Description

CROSS-REFERENCE TO RELATED APPLICATION
• This application claims the benefit of Korean Patent Application No. 10-2006-0083383, filed on Aug. 31, 2006, which is hereby incorporated by reference in its entirety as if fully set forth herein.
BACKGROUND OF THE INVENTION
• 1. Field of the Invention
• The present invention relates to an auxiliary dryer, and more particularly, to an auxiliary dryer that can be coupled to a general laundry machine. Also, the present invention relates to a multiple laundry machine constructed in a structure in which the auxiliary dryer is coupled to the general laundry machine.
• 2. Discussion of the Related Art
• Generally, laundry machines are electric home appliances that are capable of washing and/or drying laundry. Specifically, the respective laundry machines perform a washing operation, a drying operation, or a washing-and-drying operation. Recently, there has been increasingly used a laundry machine, including a steam supply unit, that is capable of performing a refreshing operation to remove wrinkles, smells, and static electricity from laundry.
• Based on the direction in which laundry is removed, the conventional laundry machines may be classified into a front loading type laundry machine and a top loading type laundry machine. Based on the washing method, on the other hand, the conventional laundry machines may be classified into a vertical-shaft type laundry machine, in which a pulsator or a washing tub is rotated, and a horizontal type laundry machine. A representative example of the horizontal type laundry machine is a drum type washing machine or a drum type drying machine.
• The sizes of the laundry machines have been gradually increased to satisfy consumers' demand. Specifically, the exterior sizes of the laundry machines for home use have been gradually increased.
• On the other hand, there is a washing machine having no drying function among the conventional laundry machines. In this case, it is required for a user to have an additional drying machine, when the user wishes to dry laundry. Alternatively, it is required for the user to have a washing machine including a drying function. Consequently, the expense that consumers bear to performing both the washing operation and the drying operation is increased.
• For laundry machines with drying functions, the sizes of the laundry machines have been gradually increased. However, the large-sized laundry machines are operated even to dry a small quantity of laundry, with the result that energy consumption is excessively increased. Of course, a rack may be mounted in the drum, such that shoes are placed on the rack, and the rack may be maintained horizontally during the rotation of the drum to dry the shoes. In this case, however, the user must separate the rack from the drum, if necessary, and this is very troublesome.
• Furthermore, the conventional laundry machines are constructed in a structure in which the drum is rotated, and therefore, it is difficult to perform sterilization using ultraviolet rays.
• FIG. 1 is a perspective view illustrating aconventional laundry machine1.
• As shown inFIG. 1, theconventional laundry machine1 includes amain body10 forming the external appearance of the laundry machine and acontrol panel11 mounted at the front or the top of the main body. Here, thecontrol panel11 may include a control unit for controlling the operation of the laundry machine. Consequently, a user manipulates the control panel for the laundry machine to perform a laundry treating operation, such as washing or drying.
• Here, the laundry machine may be a washing machine, a drying machine, or a washing-and-drying machine.
• On the other hand, the conventional laundry machine may further include abase20 for supporting themain body10 on the floor. Themain body10 is mounted on thebase20.
• However, thebase20 is utilized only to support the conventional washing machine or drying machine. In other words, the utilizability of thebase20 is very low.
SUMMARY OF THE INVENTION
• Accordingly, the present invention is directed to an auxiliary dryer and a multiple laundry machine that substantially obviate one or more problems due to limitations and disadvantages of the related art.
• An object of the present invention is to provide an auxiliary dryer that is capable of treating a small quantity of laundry without the operation of a relatively large-sized laundry machine, thereby accomplishing convenient use and reducing the energy consumption.
• Another object of the present invention is to provide a multiple laundry machine constructed in a structure in which a drying function is easily added to a washing machine that is capable of performing only a washing operation.
• Another object of the present invention is to provide a multiple laundry machine that is capable of easily drying laundry articles, such as shoes or hats, which are difficult to be dried through a conventional drum type drying machine.
• Another object of the present invention is to provide a multiple laundry machine constructed in a structure in which an auxiliary space, such as a base for conventional laundry machines, is utilized as an auxiliary dryer.
• A further object of the present invention is to provide an auxiliary dryer that is capable of sterilizing laundry using ultraviolet rays and a multiple laundry machine including the same.
• Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

• The auxiliary dryer may be mounted and used separately from the laundry machine. Preferably, however, the auxiliary dryer is coupled to one side of the laundry machine by the coupling unit. This is because the auxiliary dryer is an auxiliary apparatus for treating laundry, and therefore, it is preferable for the laundry treating apparatuses to be located at one place in an integrated fashion such that a series of laundry treating processes are smoothly carried out. In addition, the auxiliary dryer is preferably coupled to the laundry machine in a spatial utilization aspect.
• Of course, the laundry machine may be a washing machine that washes laundry, a drying machine that dries laundry, or a washing-and-drying machine that washes and dries laundry. However, the present invention is not limited to the above-specified machines. For example, the laundry machine according to the present invention may be a spin-drying machine that only spin-dries laundry.
• Preferably, the auxiliary dryer is a base for supporting the laundry machine on the floor. Here, the laundry receiving part is preferably constructed in the form of a drawer that can be withdrawn outward from the front of the auxiliary dryer body.
• Also, the ultraviolet ray sterilizing unit may include at least one ultraviolet light emitting diode (LED) or an ultraviolet lamp.
• In another aspect of the present invention, a multiple laundry machine includes a laundry machine that performs washing or drying laundry received in a body thereof, an auxiliary dryer body having a laundry receiving part defined therein for receiving laundry, a coupling unit for coupling the auxiliary dryer body to one side of the laundry machine, and an ultraviolet ray sterilizing unit provided at the auxiliary dryer body for sterilizing the laundry, received in the laundry receiving part, using ultraviolet rays.
• Preferably, the auxiliary dryer body has a volume and height less than those of the body of the laundry machine.
• The construction of the ultraviolet ray sterilizing unit constituting the multiple laundry machine is identical to that of the ultraviolet ray sterilizing unit constituting the auxiliary dryer.
• The multiple laundry machine may further include an air supply unit for forcibly supplying air into the laundry receiving part. The air supply unit may be provided at the auxiliary dryer body. Alternatively, the air supply unit may be configured of an air supply unit provided at the laundry machine.
• In addition, the multiple laundry machine may further include a steam supply unit for supplying steam into the laundry receiving part. The steam supply unit may be provided at the auxiliary dryer body. Alternatively, the steam supply unit may be configured of a steam supply unit provided at the laundry machine.
• According to the present invention, it is possible for a user to wash laundry or dry a large quantity of laundry through the laundry machine and to dry a small quantity of laundry through the auxiliary dryer. Consequently, the convenient use of the multiple laundry machine is accomplished, and the energy consumption is reduced. Also, it is possible to easily dry laundry articles, such as shoes or hats, which are difficult to be dried through a conventional drum type drying machine. Furthermore, it is possible to sterilize laundry or the interior of the laundry receiving part through the ultraviolet ray sterilizing unit.
• It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

DETAILED DESCRIPTION OF THE INVENTION
• Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In the present invention, a laundry machine may be a washing machine, a drying machine, or a washing-and-drying machine, and a detailed description thereof will not be given.
• FIG. 2 is a perspective view illustrating a multiple laundry machine including an auxiliary dryer according to the present invention, andFIG. 3 is a sectional view schematically illustrating the multiple laundry machine.
• Referring toFIGS. 2 and 3, themultiple laundry machine100 according to the present invention includes alaundry machine body110 forming the external appearance of the multiple laundry machine, thelaundry machine body110 being constructed to receive laundry such that the laundry is washed and dried in thelaundry machine body110, anauxiliary dryer body121 having a space defined therein for receiving laundry, and acoupling unit130 for coupling theauxiliary dryer body121 to one side of thelaundry machine body110.
• Specifically, anauxiliary dryer120 according to the present invention is coupled to thelaundry machine body110 so as to constitute themultiple laundry machine100. In this case, laundry is received in thelaundry machine body110, forming the external appearance of the laundry machine, such that the laundry is washed or dried. That is, the laundry machine may be a washing machine, a drying machine, or a washing-and-drying machine.
• In themultiple laundry machine100 according to the present invention, thecoupling unit130 couples theauxiliary dryer body121 to one side of thelaundry machine body110. Details of thecoupling unit130 will be described below with reference toFIG. 4.
• According to the present invention, theauxiliary dryer body121 is mounted to one side of thelaundry machine body110. Specifically, theauxiliary dryer body121 may be mounted to the bottom of thelaundry machine body110, as shown inFIG. 2. Alternatively, theauxiliary dryer body121 may be mounted to the top of thelaundry machine body110. In the latter case, a control unit, especially acontrol panel111, of the laundry machine is preferably mounted at the front of thelaundry machine body110.
• On the other hand, theauxiliary dryer120 may be disposed at the side of the laundry machine. However, theauxiliary dryer120 is preferably located at the top or the bottom of thelaundry machine body110, in consideration of a spatial utilization aspect or a design aspect.
• Theauxiliary dryer120 has a laundry receiving part for performing an auxiliary function for laundry treatment. The laundry receiving part may be constructed in the form of adrawer122 that can be withdrawn outward from the front of theauxiliary dryer body121. Also, theauxiliary dryer120 includes anair supply unit140 mounted in theauxiliary dryer body121 for forcibly supplying air into the laundry receiving part.
• Preferably, theauxiliary dryer body121 has a volume and height less than that of thelaundry machine body110, to which theauxiliary dryer body121 is coupled.
• Also, theauxiliary dryer120 further includes asteam supply unit150 mounted in theauxiliary dryer body121 for supplying steam into the laundry receiving part. Thesteam supply unit150 includes a spray port (not shown), through which the steam is sprayed into the laundry receiving part from the upper part or the rear part of theauxiliary dryer body121.
• The operation of theair supply unit140 and thesteam supply unit150 is controlled by a control unit123. The control unit123 is preferably mounted at the front of theauxiliary dryer body121. Here, the control unit123 may includes a control panel for allowing a user to manipulate the control unit123.
• On the other hand, the control unit123 may control the operation of the auxiliary dryer separately from thecontrol panel111 of the laundry machine.
• Of course, it is possible to control the operation of the auxiliary dryer through thecontrol panel111 of the laundry machine. In this case, the omission of the control unit123 is possible.
• Theair supply unit140 includes a blowingfan141 for blowing air and a heater142 for heating air. When the blowingfan141 is operated, external air is introduced into thedrawer122, and is then discharged out of thedrawer122. The external air is heated by the heater142, and is then introduced into thedrawer122.
• The heater142 may be an electric heater or a gas heater. Preferably, however, the heater142 is an electric heater in consideration of the installation space of the auxiliary dryer.
• Consequently, theauxiliary dryer120 according to the present invention may perform a drying function through theair supply unit140. Specifically, when both the blowingfan141 and the heater142 are operated, theauxiliary dryer120 according to the present invention performs a drying function using hot air. When only the blowingfan141 is operated, theauxiliary dryer120 according to the present invention performs a drying function using room-temperature air. Here, the heater142 is preferably a heater having a capacity adjustable to change the temperature of air heated by the heater142. This is because specific clothes have a low heat resistance, and rubber products, such as shoes, have a lower heat resistance.
• Thesteam supply unit150 supplies steam into thedrawer122. The steam is brought into contact with clothes received in thedrawer122 to sterilize the clothes and remove wrinkles from the clothes. Consequently, theauxiliary dryer120 according to the present invention performs a refreshing function through thesteam supply unit150. Of course, the above-described drying function may be performed in addition to the refreshing function.
• On the other hand, theauxiliary dryer body121 is preferably provided at the upper part of the rear wall thereof with an inlet port171, through which air is introduced. Also, theauxiliary dryer body121 is preferably provided at the lower part of the rear wall thereof with anoutlet port172, through which air is discharged. The upper part of the rear wall of thedrawer122 communicates with the inlet port171, and the lower part of the rear wall of thedrawer122 communicates with theoutlet port172. Consequently, external air is introduced into thedrawer122 through the upper part of the rear wall of theauxiliary dryer body121 and the upper part of thedrawer122, and is then discharged out of thedrawer122 through the lower part of thedrawer122 and the lower part of the rear wall of theauxiliary dryer body121.
• Here, the blowingfan141, which moves air, and the heater142, which heats air, may be mounted between the rear wall of thedrawer122 and the rear wall of theauxiliary dryer body121. However, the present invention is not limited to the above-specified position, and therefore, theair supply unit140, including the blowingfan141 and the heater142, may be mounted at any position on a channel along which air is introduced and discharged.
• FIG. 3 illustrates a structure in which air is introduced through the upper part of the drawer and is discharged through the lower part of the drawer. However, it is also possible to provide a structure in which air is introduced through the lower part of the drawer and is discharged through the upper part of the drawer.
• As shown inFIG. 3, on the other hand, ashelf160, on whichlaundry162 is placed, is mounted in thedrawer122. Theshelf160 divides the inner space of thedrawer122 into upper and lower spaces such that the upper and lower spaces communicate with each other. Theshelf160 is provided to smoothly discharge air supplied to thelaundry162 out of thedrawer122.
• Preferably, theshelf160 is provided with a plurality of through-holes160a,through which air is introduced from the upper part to the lower part of thedrawer122.
• Also, theshelf160 may be mounted in an inclined fashion. In this case, it is preferable for theshelf160 to be inclined downward toward the region where air is introduced. As a result, air is uniformly supplied to the laundry placed on theshelf160.
• Preferably, the drawer is provided at the upper part of the rear wall thereof with anair guide161. Theair guide161 serves to guide air such that the air can be smoothly supplied toward the front of thedrawer122, and, at the same time, to divide the air introduction channel and the air discharge channel from each other. Consequently, the collision between the introduced air and the discharged air is minimized, and therefore, the drying efficiency is improved.
• Theauxiliary dryer120 according to the present invention further includes an ultravioletray sterilizing unit180. The ultravioletray sterilizing unit180 is mounted in theauxiliary dryer body121 for sterilizing the interior of the laundry receiving part12 and thelaundry162 placed in the laundry receiving part12. The ultravioletray sterilizing unit180 emits ultraviolet rays having a predetermined wavelength band to perform a sterilizing operation.
• The ultravioletray sterilizing unit180 may include at least one ultraviolet light emitting diode (LED) or an ultraviolet lamp. The installation of the ultraviolet LED is easier than that of the ultraviolet lamp. Furthermore, it is easy to mount a plurality of ultraviolet LEDs in theauxiliary dryer body121, whereas it is difficult to mount a plurality of ultraviolet lamps in theauxiliary dryer body121. In addition, it is easy to manufacture the ultraviolet LED such that the ultraviolet LED emits ultraviolet rays having a specific wavelength most effective in sterilization as compared to the ultraviolet lamp.
• Also, the installation space of the ultraviolet LED is less than that of the ultraviolet lamp. Furthermore, the ultraviolet LED has advantages in that the energy consumption of the ultraviolet LED is relatively low, and the life span of the ultraviolet LED is relatively long. Consequently, the ultraviolet LED is more preferably used than the ultraviolet lamp as the ultravioletray sterilizing unit180.
• Although not shown inFIG. 3, on the other hand, the ultraviolet LED may be mounted to a rotary blade (not shown) that is rotated at the upper part of thelaundry receiving part122. In this case, the ultraviolet LED may uniformly irradiate ultraviolet rays into the interior space of the laundry receiving part during the rotation of the rotary blade. At the same time, the movement of air is caused by the rotation of the rotary blade, and therefore, the ultraviolet ray sterilization effect is further improved.
• On the other hand,FIG. 3 illustrates the ultravioletray sterilizing unit180 mounted at the top of thelaundry receiving part122; however, the present invention is not limited to the above-specified position. For example, the ultravioletray sterilizing unit180 may be mounted at the side or the bottom of thelaundry receiving part122.
• The auxiliary dryer according to the present invention may perform the ultraviolet ray sterilizing operation together with the drying operation. Of course, only the ultraviolet ray sterilizing operation may be individually performed by the auxiliary dryer according to the present invention.
• It is possible to perform various kinds of drying modes through the auxiliary dryer according to the present invention.
• First, a user withdraws thedrawer122 and places a small quantity of clothes, shoes, or hats, on theshelf160. For the clothes, it is preferable for the user to spread the clothes on the shelf.
• Subsequently, the user selects a desired operation mode based on the kind of the laundry through the control unit123, including the control panel. The operation mode may include various drying modes and a refreshing mode.
• The various drying modes may be classified based on drying time or drying temperature. This may be different depending upon the kinds of laundry to be dried. For example, a drying mode having a short drying time and a high drying temperature may be selected to dry a small quantity of clothes made of cotton. On the other hand, a drying mode having a long drying time and a lower drying temperature may be selected to dry shoes.
• Specifically, air is forcibly supplied into the laundry receiving space based on the operation mode selected by the user; however, the air temperature or the air supply time may be changed.
• When the operation mode is the refreshing mode, on the other hand, high-temperature steam is supplied to the laundry. Consequently, the laundry is refreshed by the steam. Specifically, smells or wrinkles are removed from the laundry, or the laundry is sterilized. Subsequently, air may be supplied to dry the laundry, if necessary.
• FIG. 4 is an exploded perspective view of the auxiliary dryer according to the present invention.
• Referring toFIG. 4, theauxiliary dryer120 according to the present invention includes anauxiliary dryer body121 having a space defined therein for receiving clothes, and acoupling unit130 mounted to the upper part of theauxiliary dryer body121 for coupling thelaundry machine body110 and theauxiliary dryer body121 to each other. Here, theauxiliary dryer120 supports thelaundry machine body110 on the floor.
• Also, theauxiliary dryer120 is provided at the top thereof withleg supporters125 for supportinglower legs116 and117 of the laundry machine.
• Eachleg supporter125 includes a panel having a firstfitting hole126, in which acorresponding leg116 of a washer is fitted, and a secondfitting hole127, in which thecorresponding leg117 of a dryer is fitted. Therespective leg supporters125 are fixed to the top of theauxiliary dryer body121 by screws. Here, the washer and the dryer are examples of the laundry machine. The washer has an exterior size greater than that of the dryer.
• Specifically, theleg supporters125 are fixed to the top of theauxiliary dryer body121 at the respective corners of theauxiliary dryer body121. The firstfitting holes126 and the second fitting holes127 formed in the two leg supporters fixed to the front corners of theauxiliary dryer body121 are connected to each other. On the other hand, the firstfitting holes126 and the second fitting holes127 formed in the two leg supporters fixed to the rear corners of theauxiliary dryer body121 are separated from each other. This is to accomplish easy and convenient fitting of thelegs116 and117 in the corresponding fitting holes of theleg supporters125.
• Also, the firstfitting holes126 are positioned outside the corresponding second fitting holes127 on diagonal lines at the bottom of thelaundry machine body110. This is because the size of the main body of the washer is generally greater than that of the main body of the clothes dryer.
• Thecoupling unit130 includes a plurality ofcoupling members138 mounted to the lower part of the side of the washer or the clothes dryer and to the side of theauxiliary dryer body121, and a plurality of fixingmembers135 for fixing thecoupling members138 to the side of the washer or the clothes dryer and to the side of theauxiliary dryer body121.
• As shown inFIG. 3, thecoupling members138 may be provided such that twocoupling members138 fix theauxiliary dryer body121 and thelaundry machine body110 to each other at each lateral side of theauxiliary dryer body121 and thelaundry machine body110, especially at the interface between theauxiliary dryer body121, which is constructed in a hexahedral shape, and thelaundry machine body110, which is constructed in a hexahedral shape.
• In addition, additional coupling members (not shown) may be mounted to the rear of theauxiliary dryer body121 and to the rear of thelaundry machine body110 for fixing theauxiliary dryer body121 and thelaundry machine body110 to each other.
• Thecoupling unit130 may be modified depending upon the change in height of thelegs116 of the washer or thelegs117 of the clothes dryer.
• Each fixingmember135 includes a first fixingmember136 for fixing the upper part of the correspondingcoupling member138 to the lower part of the washer or the clothes dryer at each lateral side of the washer or the clothes dryer, and asecond fixing member137 for fixing the lower part of the correspondingcoupling member138 to the upper part of theauxiliary dryer body121 at each lateral side of theauxiliary dryer body121.
• Here, at least one of the first fixingmember136 and the second fixingmember137 may be a member having an adhesive material applied to opposite major surfaces thereof, for example, a double-sided adhesive tape.
• On the other hand, at least one of the first fixingmember136 and the second fixingmember137 may be a connecting member, such as a screw.
• When the fixing member is the screw, connection holes are preferably formed at thecorresponding coupling member138 while the connection holes are spaced a predetermined distance from each other.
• Unlike the above description, on the other hand, the means for coupling between thelaundry machine body110 and theauxiliary dryer body121 may be modified in various forms.
• According to the present invention, the volume of theauxiliary dryer body121 is preferably less than that of thelaundry machine body110, to which theauxiliary dryer body121 is fixed. Also, the height of theauxiliary dryer body121 is preferably less than that of thelaundry machine body110. This is because the auxiliary dryer according to the present invention is constructed to perform an auxiliary function of the laundry machine.
• In consideration of the safety and the external design of themultiple laundry machine100, it is preferable that at least one of the left-to-right width and the front-to-rear width of theauxiliary dryer body121 be equal to or greater than the left-to-right width or the front-to-rear width of thelaundry machine body110, when the auxiliary dryer serves as a base for supporting the laundry machine. When the auxiliary dryer is fixed to the top of the laundry machine, on the other hand, it is preferable that at least one of the left-to-right width and the front-to-rear width of theauxiliary dryer body121 be equal to or less than the left-to-right width or the front-to-rear width of thelaundry machine body110.
• Hereinafter, a multiple laundry machine according to another embodiment of the present invention will be described with reference toFIG. 5.
• In the previously described embodiment, theair supply unit140, which forcibly supplies air into thelaundry receiving part122 of theauxiliary dryer120, is mounted in theauxiliary dryer body121. In this embodiment, on the other hand, an air supply unit is mounted in thelaundry machine body110. Specifically, this embodiment is characterized in that air is forcibly supplied into thelaundry receiving part122 of theauxiliary dryer120 by the operation of the air supply unit mounted in thelaundry machine body110.
• As shown inFIG. 5, the air supply unit is mounted in thelaundry machine body110 for forcibly supplying air into adrum40 of the laundry machine. The air supply unit includes aheater90 for heating air and a blowingfan60 for blowing air. In addition, the air supply unit further includes a dryingchannel44 for guiding air such that the air is introduced into thedrum40 and adischarge channel80 for guiding air such that the air is discharged from thedrum40.
• The air supply unit supplies air into thedrum40, and, in addition, air into the interior space of the auxiliary drier120, i.e., thelaundry receiving part122. To this end, the air supply unit further includes anauxiliary drying channel45 and anauxiliary discharge channel81.
• Theauxiliary drying channel45 may diverge from the dryingchannel44. One end of theauxiliary drying channel45 is connected to a through-hole271 formed at one side of abase212. The through-hole271 communicates with anintroduction port128 formed at the top of theauxiliary dryer body121 such that dried air is introduced into the interior space of the drawer.
• Theauxiliary discharge channel81 may diverge from thedischarge channel80. One end of theauxiliary discharge channel81 is connected to a through-hole272 formed at the other side of thebase212. The through-hole272 communicates with adischarge port129 formed at the top of theauxiliary dryer body121 such that air is discharged from the interior space of the drawer, i.e., thelaundry receiving part122.
• However, thedischarge port129 may not be connected to the through-hole272. Specifically, air may be directly discharged from the interior space of thelaundry receiving part122 through thedischarge port129. In this case, the omission of theauxiliary discharge channel81 is possible.
• On the other hand, theheater90 is preferably mounted in the dryingchannel44 at a position where theauxiliary drying channel45 does not diverge from the dryingchannel44. In this case, it is possible to supply hot air into the,drum40 and thedrawer122 by the provision of only a single heater. Of course, room-temperature air is supplied into thedrum40 and thedrawer122, when the heater is not operated.
• Also, the blowingfan60 is preferably mounted in thedischarge channel80 at a position where theauxiliary discharge channel81 diverges from thedischarge channel80. In this case, it is possible to supply air into thedrum40 and thelaundry receiving part122 by the provision of only a single blowing fan.
• Themultiple laundry machine100 according to the present invention supplies air into the drum, and, in addition, air into thelaundry receiving part122. According to circumstances, it is possible to supply air into the drum or the drawer. Of course, it is possible to supply air into the both the drum and the drawer. To this end, channel opening and closing members, such asdampers280, may be mounted in the dryingchannel44 and theauxiliary drying channel45 for selectively opening and closing the dryingchannel44 and theauxiliary drying channel45.
• On the other hand, themultiple laundry machine100 according to the present invention may further include asteam supply unit300 mounted in thelaundry machine body110 for supplying steam into thedrum40 and thelaundry receiving part122. Specifically, this embodiment is characterized in that steam is supplied into thelaundry receiving part122 by thesteam supply unit300 mounted in thelaundry machine body110.
• Thesteam supply unit300 includes asteam spray port350 for spraying steam into the drum and a steam spray port (not shown) for spraying steam into the drawer. Consequently, it is possible to supply steam into the drum or the drawer through the steam spray ports.
• Unlike the above description, on the other hand, only a singlesteam spray port355 may be provided to supply steam into the drum and thelaundry receiving part122. In this case, thesteam spray port355 sprays steam into the dryingchannel44 at a position where theauxiliary drying channel45 does not diverge from the dryingchannel44. Specifically, when steam is sprayed into the dryingchannel44, the sprayed steam is supplied into the drum and the laundry receiving part through the dryingchannel44 and theauxiliary drying channel45, respectively. In this case, thefan60 is also preferably operated. Furthermore, it is not necessary to form an introduction port, through which steam is supplied into theauxiliary dryer body121, at theauxiliary dryer body121. This is because the steam is supplied through theauxiliary drying channel45.
• According to the present invention, the supply of steam into the drum and the drawer is to refresh laundry. Specifically, high-temperature steam is supplied to the drum and the laundry receiving part to remove wrinkles from the laundry, prevent the generation of static electricity, remove smells from the laundry, and sterilize the laundry. Consequently, it is preferable to supply heated dried air into the drum and the drawer after the supply of the steam. This is to remove moisture, which may remain in some clothes, from the clothes, such that a user can immediately wear the clothes.
• According to the present invention, the operation of theheater90, the blowingfan60, thedampers280, and thesteam supply unit300 is controlled by a control unit (not shown). The control unit is preferably mounted at the front of thelaundry machine body110. Here, the control unit may include acontrol panel111 for allowing a user to manipulate the control unit.
• Consequently, it is possible to selectively supply air into the drum and the laundry receiving part under the control of the control unit. Also, it is possible to control the temperature of the air and the supply time of the air. Furthermore, it is possible to selectively supply steam into the drum and the laundry receiving part under the control of the control unit.
• According to the present invention, theheater90 is preferably a heater having a capacity adjustable to change the temperature of air heated by theheater90. This is because specific clothes have a low heat resistance, and especially rubber products, such as shoes, have a lower heat resistance. The adjustment of the capacity of theheater90 may be controlled by the control unit.
• On the other hand, the multiple laundry machine according to this embodiment includes an ultraviolet ray sterilizing unit identical to that of the previously described embodiment.
• In this embodiment, a discharge type drying machine is illustrated and described as the laundry machine according to the present invention. However, the present invention is not limited to the above-specified type drying machine. For example, the present invention is applicable to a condensation type drying machine.
• As apparent from the above description, the present invention provides an auxiliary dryer that is capable of treating a small quantity of laundry without the operation of a relatively large-sized laundry machine. Consequently, the present invention has the effect of accomplishing convenient use and reducing the energy consumption.
• Also, the present invention provides a multiple laundry machine constructed in a structure in which a drying function is easily added to a washing machine that is capable of performing only a washing operation.
• Furthermore, the present invention provides a multiple laundry machine that is capable of easily drying laundry articles, such as shoes or hats, which are difficult to be dried through a conventional drum type drying machine. Also, the multiple laundry machine is constructed in a structure in which an auxiliary space, such as a base for conventional laundry machines, is utilized as an auxiliary dryer.
• Consequently, the present invention has the effect of manufacturing the multiple laundry machine at low costs, and maximizing the spatial utilization of the multiple laundry machine, thereby accomplishing convenient use of the multiple laundry machine.
• In addition, the present invention has the effect of sterilizing laundry using ultraviolet rays, thereby improving the sterilizing efficiency.
• It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
