                         技术领域Technical field

本发明涉及一种滚筒式洗衣机，尤其涉及这样一种滚筒式洗衣机，其中在向上倾斜安装以使要洗涤的衣物容易地装入和取出的旋转桶的内部外围表面的周边排列的轴向伸展的提升器(lifter)具有改善的结构，因此，能够在洗涤性能上获得改善。The present invention relates to a drum type washing machine, and more particularly to a drum type washing machine in which axially extending The lifter has an improved structure, and thus, can be improved in washing performance.

                         背景技术 Background technique

传统的洗衣机一般包括：壳体，形成洗衣机的外观；柱状水桶，安装在壳体中并适于容纳洗涤水；柱状旋转桶，旋转地安装在水桶内并适于洗涤其中容纳的衣物；驱动电机，安装在水桶后面并适于使旋转桶旋转；和门，以铰链形式安装在壳体前壁。A conventional washing machine generally includes: a casing forming the appearance of the washing machine; a cylindrical water tub installed in the casing and adapted to receive washing water; a cylindrical rotating tub rotatably installed in the water tub and adapted to wash laundry contained therein; a driving motor , installed behind the bucket and adapted to rotate the rotating bucket; and a door, hingedly installed on the front wall of the housing.

不同的提升器从旋转桶的内部外围表面突出到希望的高度，绕旋转桶圆周地相互间隔地排列，并沿旋转桶的内部外围表面轴向地伸展。当旋转桶旋转时，提升器以连续的方式将旋转桶中的衣物和洗涤水提升，然后抛下，从而洗涤衣物。The different lifters protrude to desired heights from the inner peripheral surface of the rotary tub, are arranged at intervals from each other circumferentially around the rotary tub, and extend axially along the inner peripheral surface of the rotary tub. When the rotary tub rotates, the lifter continuously lifts the clothes and washing water in the rotary tub, and then throws them down, thereby washing the clothes.

在水桶和旋转桶各自的前端提供了开口，从而可以通过门将它们打开和关闭。当打开门时，可通过开口将衣物放入旋转桶或通过开口将衣物从旋转桶中取出。当关闭门时，水桶和旋转桶与门的外边是密封的。在这种状态下，可进行洗涤循环。Openings are provided at the respective front ends of the bucket and the rotary bucket so that they can be opened and closed by a door. When the door is opened, laundry can be put into the rotary tub through the opening or taken out from the rotary tub through the opening. When the door is closed, the bucket and rotating bucket are sealed to the outside of the door. In this state, a wash cycle can be performed.

在具有上述结构的滚筒式洗衣机中，通过安装在壳体前壁的门来装入和取出衣物。但是，由于上述滚筒式洗衣机的壳体典型地具有比人的平均高度低得多的高度，并且旋转桶的开口在向前的方向，所以为了在打开门之后通过旋转桶的开口装入和取出衣物，用户必须弯腰以降低姿势。因此，存在不便。In the drum type washing machine having the above structure, laundry is loaded and unloaded through a door installed on the front wall of the housing. However, since the casing of the above-mentioned drum type washing machine typically has a height much lower than the average height of a person, and the opening of the rotary tub is in the forward direction, in order to load and take it out through the opening of the rotary tub after opening the door, clothing, the user must bend over to lower the posture. Therefore, there is inconvenience.

为了消除这些不便，近来提出了改善的滚筒式洗衣机。在这种滚筒式洗衣机中，旋转桶向上倾斜从而其开口在向上的方向上，因此用户不需要太弯腰就可进行衣物的装入和取出。In order to eliminate these inconveniences, improved drum type washing machines have recently been proposed. In such a drum type washing machine, the rotary tub is inclined upward so that its opening is in an upward direction, so a user does not need to stoop too much to load and take out laundry.

在这种其中滚筒是倾斜的结构中，相对大量的衣物位于旋转桶的后端部分，而量相对小的衣物位于旋转桶的前端部分。尤其是，由于在旋转桶的内部外围表面上的提升器具有贯穿旋转桶的长度的不变的高度，所以位于旋转桶后端部分的衣物被堆在比提升器的高度相当高的水平面上，而位于旋转桶的前端部分的衣物被堆在比提升器的高度低的水平面上。In such a structure in which the drum is inclined, a relatively large amount of laundry is located at a rear end portion of the rotary tub, and a relatively small amount of laundry is located at a front end portion of the rotary tub. Especially, since the lifter on the inner peripheral surface of the rotary tub has a constant height throughout the length of the rotary tub, the laundry located at the rear end portion of the rotary tub is piled on a considerably higher level than the height of the lifter, And the clothes positioned at the front end of the rotary tub are piled on a level lower than the height of the lifter.

当旋转桶在这种状态下旋转时，提升器可能不能提升在旋转桶的后端部分位于比提升器的高度高的水平面上的衣物，因此不能有效的洗涤衣物。另一方面，在旋转桶的前端部分被提升器提升的衣物的量相对较小。结果，提升器的运行效率低。When the rotary tub is rotated in this state, the lifter may not be able to lift laundry located at a level higher than that of the lifter at a rear end portion of the rotary tub, and thus the laundry may not be effectively washed. On the other hand, the amount of laundry lifted by the lifter at the front end portion of the rotary tub is relatively small. As a result, the lifter operates inefficiently.

另外，当提升器随着旋转桶旋转时，在旋转桶的后端部分没有被提升器提升的衣物可能被缠住。其结果是，可能会损坏衣物。还有不便之处是，用户必须在完成洗涤过程后将缠住的衣物解开。In addition, when the lifter rotates with the rotary tub, laundry that is not lifted by the lifter at the rear end portion of the rotary tub may be caught. As a result, laundry may be damaged. There is also the inconvenience that the user has to untangle the entangled laundry after completing the washing process.

同时，在旋转桶的前端部分分布的相对较小量的衣物很容易地被提升器提升，然后向着旋转桶的后端部分移动。其结果是，衣物甚至更容易在旋转桶的后端部分揉成一团。Meanwhile, a relatively small amount of laundry distributed at the front end portion of the rotary tub is easily lifted by the lifter, and then moves toward the rear end portion of the rotary tub. As a result, the laundry is even more prone to bunching up in the rear end portion of the rotary tub.

当衣物主要位于旋转桶的后端部分时，由于相对大的负载施加于旋转桶的后端部分，而相对小的负载施加于旋转桶的前端部分，因此会产生动力不平衡。结果，旋转桶的旋转操作运行效率低。When the laundry is mainly located at the rear end portion of the rotary tub, since a relatively large load is applied to the rear end portion of the rotary tub and a relatively small load is applied to the front end portion of the rotary tub, power imbalance may occur. As a result, the rotating operation of the rotating bucket operates inefficiently.

由于传统的滚筒式洗衣机的旋转桶向上倾斜并向前伸展，并且排列在其上的提升器具有不变的高度，所以与洗涤剂混合并被引入在提升器的前端部分的旋转桶的底部的洗涤水随着提升器向上的运动被提升，然后通过设置在提升器上的喷水孔向下喷洒。然而，通过喷水口喷出的洗涤水的量很小。大量的洗涤水流向提升器的后端部分。因为这个原因，位于旋转桶前端部分的衣物不能充分地浸泡在洗涤水中，因此不能有效地洗涤衣物。Since the rotary tub of the conventional front-loading washing machine is inclined upward and stretched forward, and the lifter arranged on it has a constant height, the detergent is mixed with the detergent and introduced into the bottom of the rotary tub at the front end of the lifter. The washing water is lifted along with the upward movement of the lifter, and then sprayed downward through the water spray holes arranged on the lifter. However, the amount of wash water sprayed through the water spray port is small. A large amount of wash water flows to the rear end portion of the lifter. For this reason, the laundry at the front end portion of the rotary tub is not sufficiently soaked in the wash water, and thus the laundry cannot be effectively washed.

                       具体实施方式 Detailed ways

以下，参照附图来详细说明本发明的实施例，其例子列举在附图中，其中相同的标号始终表示相同的部件。下面参照附图描述实施例以解释本发明。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, examples of which are illustrated in the accompanying drawings, in which like reference numerals designate like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

图1是示意性地表示根据本发明的滚筒式洗衣机的结构的截面示图。如图1中所示，为了洗涤和脱水甩干装入旋转桶3中的衣物，根据本发明的滚筒式洗衣机包括：壳体1，近似于盒状，以限定洗衣机的外观；鼓形水桶2，安装于壳体1中并适于容纳洗涤水；鼓形旋转桶3，旋转地位于水桶2中并具有位于旋转桶的外围壁上的离心脱水孔4；和以使旋转桶3旋转的电机5。FIG. 1 is a sectional view schematically showing the structure of a drum type washing machine according to the present invention. As shown in Figure 1, in order to wash and spin dry the clothes loaded into therotary tub 3, the drum type washing machine according to the present invention comprises: a housing 1, which is approximately box-shaped, to limit the appearance of the washing machine; a drum-shaped bucket 2 , installed in the housing 1 and adapted to accommodate washing water; a drum-shapedrotary tub 3, rotatably positioned in the water tub 2 and having acentrifugal dehydration hole 4 positioned on the peripheral wall of the rotary tub; and a motor to rotate therotary tub 3 5.

在水桶2和旋转桶3各自的前端提供了开口2a和3a，以使得将衣物放入旋转桶3和从旋转桶3中取出。门6以铰链形式安装于壳体1的前壁上，以打开和关闭水桶2和旋转桶3的开口2a和3a。Openings 2 a and 3 a are provided at respective front ends of the water tub 2 and therotary tub 3 so that laundry is put into and taken out of therotary tub 3 . A door 6 is hingedly installed on the front wall of the housing 1 to open and close the openings 2a and 3a of the water tub 2 and therotary tub 3 .

壳体1的顶部安装了用来接收来自外部水源的洗涤水供水管7和用来容纳洗涤剂的洗涤剂容器8，并将洗涤剂和经供水管7提供的洗涤水混合。排水泵9和排水管10安装于壳体1的底部，以在完成洗衣循环后向外界排出洗涤水。A washing water supply pipe 7 for receiving from an external water source and adetergent container 8 for containing detergent are installed on the top of the housing 1, and the detergent is mixed with the washing water provided through the water supply pipe 7. A drain pump 9 and adrain pipe 10 are installed at the bottom of the casing 1 to drain the washing water to the outside after the washing cycle is completed.

在水桶2的外面驱动电机5固定地安装在水桶2的后端。其一端连接驱动电机5的旋转轴5a的另一端固定地连接在旋转水桶3的后端，从而将旋转力从驱动电机5传送到旋转桶3，因此使得旋转桶3旋转。The drive motor 5 is fixedly installed on the rear end of the water bucket 2 outside the water bucket 2 . One end of which is connected to therotating shaft 5a of the drive motor 5 and the other end is fixedly connected to the rear end of therotary bucket 3 so as to transmit rotational force from the drive motor 5 to therotary bucket 3, thus causing therotary bucket 3 to rotate.

旋转桶3以一定的角度α(图2)向着壳体1的前壁向上地倾斜，以使用户无需弯腰就可将衣物装入和取出。类似地，水桶2以与旋转桶3的倾斜角α相等的角度向上地倾斜，并悬挂在壳体1中。当然，在某些情况下水桶2和旋转桶3可具有不同的倾斜角。Therotary tub 3 is inclined upward toward the front wall of the housing 1 at a certain angle α ( FIG. 2 ), so that the user can load and take out clothes without bending over. Similarly, the water tub 2 is inclined upward at an angle equal to the inclination angle α of therotary tub 3 and suspended in the housing 1 . Of course, the water bucket 2 and therotating bucket 3 may have different inclination angles in some cases.

其优点是旋转桶3的倾斜角可以尽可能的大，以方便地在壳体1的前面装入和取出衣物。然而，当倾斜角α过大时，位于旋转桶的3的后端部分的衣物的量也过多地增加，从而会发生洗涤性能的恶化。因此，考虑到装入和取出衣物的操作的方便和洗衣性能，最好将旋转桶3的倾斜角α确定在大约5°到15°范围内。Its advantage is that the inclination angle of therotary tub 3 can be as large as possible, so that the clothes can be loaded and taken out in front of the housing 1 conveniently. However, when the inclination angle α is too large, the amount of laundry at the rear end portion of therotary tub 3 also increases excessively, so that deterioration of washing performance may occur. Therefore, it is preferable to determine the inclination angle α of therotary tub 3 to be in the range of about 5° to 15° in consideration of convenience of loading and unloading of laundry and laundry performance.

提升器20排列在旋转桶3的内部外围表面上，从而当沿着旋转桶3轴向地伸展时围绕旋转桶3在圆周上彼此间隔均匀地排列。当旋转桶3旋转时，提升器20将旋转桶3中的衣物与洗涤水一起提升，然后在一定的水平面释放提升的衣物和洗涤水，从而抛下衣物和洗涤水。因此，洗涤了衣物。Thelifters 20 are arranged on an inner peripheral surface of therotary tub 3 so as to be evenly spaced from each other on a circumference around therotary tub 3 when extending axially along therotary tub 3 . When therotary tub 3 rotates, thelifter 20 lifts the laundry in therotary tub 3 together with the washing water, and then releases the lifted laundry and washing water at a certain level, thereby dropping the laundry and the washing water. Therefore, the laundry is washed.

由于旋转桶3向着壳体1的前壁向上倾斜的布置，与和门6连接的旋转桶3的前端部分相比，旋转桶3中容纳的衣物可能主要位于与壳体1的后壁相连的旋转桶的后端部分。为了有效地提升处于这种状态的衣物，提升器20具有随着从旋转桶3的后端向着其前端延伸而逐渐降低的高度。将在后面参照图2至5对提升器的这种结构进行描述。Due to the upwardly inclined arrangement of therotary tub 3 towards the front wall of the casing 1, compared with the front end portion of therotary tub 3 connected to the door 6, the clothes contained in therotary tub 3 may be mainly located at the rear wall connected to the casing 1. Rotate the back end part of the bucket. In order to effectively lift the laundry in this state, thelifter 20 has a gradually decreasing height extending from the rear end of therotary tub 3 toward the front end thereof. Such a structure of the lifter will be described later with reference to FIGS. 2 to 5 .

图2和3是分别表示图1中所示的排列在旋转桶的内部外围表面上的提升器的结构的截面示图和透视图。2 and 3 are a sectional view and a perspective view, respectively, showing the structure of lifters arranged on the inner peripheral surface of the rotary tub shown in FIG. 1 .

如图2所示，旋转桶3以α角朝着壳体1(图1)的前壁向上倾斜，从而旋转桶的中心轴，即中心线C₁-C₁，与水平线H₁-H₁以角度α相交。按照这种布置，与旋转桶3的前端部分相比，相对大量的衣物位于旋转桶3的后端部分。As shown in Fig. 2, therotating barrel 3 is inclined upwards towards the front wall of the housing 1 (Fig. 1) at an angle α, so that the central axis of the rotating barrel, that is, the center line C₁ -C₁ , is aligned with the horizontal line H₁ -H₁ Intersect at angle α. According to this arrangement, a relatively large amount of laundry is located at the rear end portion of therotary tub 3 compared to the front end portion of therotary tub 3 .

类似地，每个提升器20具有随着其从旋转桶3的后端向前端延伸具有逐渐减小的高度，从而分别沿着提升器的顶部和底部21和22延伸的线以角度α相交。根据这种结构，当提升器20位于旋转桶3的最低水平面时，提升器20的顶部21与水平线H₁-H₁平行。Similarly, eachriser 20 has a gradually decreasing height as it extends from the rear end to the front end of therotary tub 3 so that lines extending along the top and bottom 21 and 22 of the riser, respectively, intersect at an angle α. According to this structure, when thelifter 20 is located at the lowest level of therotary tub 3, the top 21 of thelifter 20 is parallel to the horizontal line_H1 -_H1 .

这里，每个提升器20的底部22是与旋转桶3的内部外围表面接触的提升器部分，而每个提升器20的顶部21是与旋转桶3的内部外围表面离开最大距离的提升器部分。Here, the bottom 22 of eachlifter 20 is the lifter portion that is in contact with the inner peripheral surface of therotary tub 3, and the top 21 of eachlifter 20 is the lifter portion that is separated from the inner peripheral surface of therotary tub 3 by the greatest distance. .

按照其这种结构，当位于旋转桶3的最低水平面时，提升器20在其具有相对大的高度的后端部分可以提升起相对大量的衣物，而在起具有相对小的高度的后端部分提升相对小量的衣物。因此，旋转桶3被维持在动态平衡状态。所以可以在平稳旋转时均匀的洗涤所有的衣物。According to its structure, when located at the lowest level of therotary tub 3, thelifter 20 can lift a relatively large amount of clothing at its rear end portion with a relatively large height, and at the rear end portion with a relatively small height. Lift relatively small quantities of laundry. Therefore, therotary tub 3 is maintained in a dynamic equilibrium state. So all laundry can be washed evenly while spinning smoothly.

由于在洗涤过程中，相对小量的衣物分布在具有相对小的高度的提升器20的前端部分，因此不会发生位于提升器20的前端部分的衣物向着旋转桶3的后端部分的移动。Since a relatively small amount of laundry is distributed at the front end portion of thelifter 20 having a relatively small height during washing, the laundry located at the front end portion of thelifter 20 does not move toward the rear end portion of therotary tub 3 .

如图3中所示，提升器20围绕着旋转桶3排列，当从旋转桶3的后端向其前端轴向延伸时，即贯穿于旋转桶3的整个长度，它们在圆周上彼此均匀的隔开。因此，提升器20可以有效地提升容纳在旋转桶3中的所有衣物。As shown in Figure 3, thelifters 20 are arranged around therotating bucket 3, and when extending axially from the rear end of therotating bucket 3 to its front end, that is, throughout the entire length of therotating bucket 3, they are uniformly aligned with each other on the circumference. separated. Therefore, thelifter 20 can effectively lift all the laundry contained in therotary tub 3 .

每个提升器20的顶部21具有不变的宽度，且具有喷水孔23。喷水孔23纵向排列为几行。The top 21 of eachriser 20 has a constant width and has water spray holes 23 . The spray holes 23 are vertically arranged in several rows.

每个提升器20还具有用以喷洒洗涤水的结构。即，每个提升器20具有向下敞开的中空结构以在其内部接收洗涤水。另外，在旋转桶3与提升器20中的一个相连的部分提供了开口27。此外，每个提升器20的底部22是敞开的以和与其连接的开口27连通。当提升器20位于其最低水平面时，可通过与其相连的开口27和其打开的较低端22将洗涤水引入提升器20的内部。Eachlifter 20 also has a structure to spray wash water. That is, eachlifter 20 has a hollow structure opened downward to receive wash water inside. In addition, anopening 27 is provided at a portion where therotary tub 3 is connected to one of thelifters 20 . Furthermore, the bottom 22 of eachlifter 20 is open to communicate with anopening 27 connected thereto. When theriser 20 is at its lowest level, wash water can be introduced into the interior of theriser 20 through theopening 27 associated therewith and its openlower end 22 .

因此，经在旋转桶3的底端的敞开的提升器的底部22引入各提升器20内部的洗涤水通过在旋转桶3的顶部的喷水孔23向下喷洒。因此，与洗涤剂混合的洗涤水可以渗透衣物，从而可以快速地洗涤衣物。Therefore, the wash water introduced into the inside of eachlifter 20 through the bottom 22 of the open lifter at the bottom end of therotary tub 3 is sprayed downward through thewater spray hole 23 at the top of therotary tub 3 . Therefore, the washing water mixed with the detergent can permeate the clothes, so that the clothes can be washed quickly.

尽管没有在图中表示，但是可以在各提升器20的对应端部分提供喷水孔，以从侧面喷洒洗涤水。Although not shown in the drawings, water spray holes may be provided at corresponding end portions of eachlifter 20 to spray wash water from a side.

如图4和5中所示，在每个提升器20的内部提供了一对凸台24从而使它们和提升器成为一体。凸台24从提升器20的顶部21的内部表面向下凸出。在每个凸台24的凸出端形成螺纹连接孔25。因此，可以在旋转桶3的外边通过将连接螺钉26穿过备个连接孔25将提升器20安装在旋转桶3上。As shown in Figures 4 and 5, a pair ofbosses 24 are provided inside eachlifter 20 so that they are integral with the lifter.Bosses 24 protrude downward from the inner surface of the top 21 of thelifter 20 . A threadedconnection hole 25 is formed at the protruding end of eachboss 24 . Therefore, thelifter 20 can be installed on therotary tub 3 by passing the connectingscrew 26 through the first connectinghole 25 outside therotary tub 3 .

同时，因为由于提升器20具有向着旋转桶3的前端逐渐减小的高度，根据运动提升器20的前端部分比提升器20的后端部分位于更高的水平面，随着提升器从旋转桶3的底部向其顶部移动，经在旋转桶3的底部的提升器20的敞开的底部22引入各个提升器20的内部的洗涤水可能向着提升器20的后端部分流动。结果，相对小量的洗涤水通过在提升器20的前端部分的喷水孔23喷洒。相反，洗涤水主要通过在提升器20的后端部分的喷水孔23喷洒。Simultaneously, because the front end portion of thelifter 20 is located at a higher level than the rear end portion of thelifter 20 according to the motion due to thelifter 20 having a height that gradually decreases toward the front end of therotary bucket 3, as the lifter moves from therotary bucket 3 The bottom of eachlifter 20 moves toward its top, and the wash water introduced into the interior of eachlifter 20 through theopen bottom 22 of thelifter 20 at the bottom of therotary tub 3 may flow toward the rear end portion of thelifter 20 . As a result, a relatively small amount of wash water is sprayed through thewater spray hole 23 at the front end portion of thelifter 20 . On the contrary, the wash water is mainly sprayed through the water spray holes 23 at the rear end portion of thelifter 20 .

为了避免这种现象，每个提升器具有排列其内部的分隔板。以下将参照显示了一个提升器的内部结构的图4和5描述这种结构。In order to avoid this phenomenon, each riser has partition plates lining its interior. This structure will be described below with reference to Figures 4 and 5 showing the internal structure of a lifter.

参照图4和5，根据本发明的提升器20包括：第一和第二分隔板31和32，排列在提升器20的内部，以当纵向地彼此隔开一定距离时横向伸展。提升器20的内部被分隔板31和32分为第一到第三室41至43。Referring to FIGS. 4 and 5 , thelifter 20 according to the present invention includes first andsecond partition plates 31 and 32 arranged inside thelifter 20 to extend laterally while being longitudinally spaced from each other by a certain distance. The interior of thelifter 20 is divided into first tothird chambers 41 to 43 by thepartition plates 31 and 32 .

由于第一分隔板31，当关联的提升器20位于旋转桶3的顶端时，位于相对高的水平面的第一室41容纳的洗涤水不会流向第二室42。同样，由于第二分隔板32，第二室42容纳的洗涤水不会流向第三室43。Due to thefirst partition plate 31 , when the associatedlifter 20 is located at the top end of therotary tub 3 , the wash water contained in thefirst chamber 41 located at a relatively high level does not flow to thesecond chamber 42 . Also, the wash water contained in thesecond chamber 42 does not flow to thethird chamber 43 due to thesecond partition plate 32 .

因此，在提升器20的前端的第一室41容纳的洗涤水只喷洒在旋转桶3的前端部分，而在提升器20的中部的第二室42容纳的洗涤水只喷洒在旋转桶的中部。同样，在提升器20的后端部分的第三室43容纳的洗涤水只喷洒在旋转桶3的后端部分。Therefore, the washing water contained in thefirst chamber 41 at the front end of thelifter 20 is sprayed only at the front end portion of therotary tub 3, and the washing water contained in thesecond chamber 42 at the middle of thelifter 20 is sprayed only at the middle of the rotary tub. . Also, the wash water contained in thethird chamber 43 at the rear end portion of thelifter 20 is sprayed only on the rear end portion of therotary tub 3 .

为了从第一至第三室41至43中分别喷洒出大约等量的洗涤水，排列第一和第二分隔板31和32以适当地分隔提升器20的内部，从而第一至第三室41至43具有大约相等的容积。为此，第一和第二分隔板31和32向着提升器20的前端倾斜，从而每个分隔板的上端比分隔板的下端离提升器20的前端更近。另外，第一和第二分隔板31和32分别具有不同的倾角。In order to spray approximately equal amounts of wash water from the first tothird chambers 41 to 43, respectively, the first andsecond partition plates 31 and 32 are arranged to properly partition the inside of thelifter 20 so that the first tothird chambers Chambers 41 to 43 have approximately equal volumes. For this, the first andsecond partition plates 31 and 32 are inclined toward the front end of thelifter 20 such that the upper end of each partition plate is closer to the front end of thelifter 20 than the lower end of the partition plate. In addition, the first andsecond partition plates 31 and 32 have different inclination angles, respectively.

根据这种安排，第一和第二分隔板31和32将提升器20的顶部21分为三个分别具有不同但大约相等的长度的部分。第一和第二分隔板31和32的较低端将提升器20的底部22分为三部分，从而相应于第一室41的部分具有最大的长度，相应于第三室43的部分具有最小的长度。因此，第一至第三室41至43分别具有大约相等的容积。According to this arrangement, the first andsecond partition plates 31 and 32 divide the top 21 of thelifter 20 into three sections each having different but approximately equal lengths. The lower ends of the first andsecond dividing plates 31 and 32 divide the bottom 22 of thelifter 20 into three parts, so that the part corresponding to thefirst chamber 41 has the largest length, and the part corresponding to thethird chamber 43 has the largest length. Minimum length. Therefore, the first tothird chambers 41 to 43 have approximately equal volumes, respectively.

尽管提升器被描述为具有被两个隔板31和33所限定的三个室41至43的结构，但是可以通过在提升器内部排列更多数目的分隔板来限定更多数目的室。在这种情况下，可通过在提升器顶部形成的所有喷水孔来更均匀地喷洒与洗涤剂混合的洗涤水。Although the riser is described as having a structure of threechambers 41 to 43 defined by twopartitions 31 and 33, a greater number of chambers may be defined by arranging a greater number of partitions inside the riser. In this case, the wash water mixed with detergent can be sprayed more uniformly through all the water spray holes formed on the top of the lifter.

现在，将描述通过具有根据本发明的上述结构的滚筒式洗衣机洗涤衣物的过程。Now, a process of washing laundry by the drum type washing machine having the above structure according to the present invention will be described.

首先，用户打开门6，将衣物放入向上倾斜的旋转桶3中。此时，用户可以无需降低其姿势方便地进行这些操作。衣物分布在旋转桶3中，从而相对大量的衣物位于旋转桶3的后端部分，而相对小量的衣物位于旋转桶3的前端部分。First, the user opens the door 6 and puts the laundry into the upwardly inclinedrotary tub 3 . At this time, the user can conveniently perform these operations without lowering his posture. The laundry is distributed in therotary tub 3 such that a relatively large amount of laundry is located at a rear end portion of therotary tub 3 and a relatively small amount of laundry is located at a front end portion of therotary tub 3 .

其后，用户关上门6，并操作控制板(未表示)以运转洗衣机。随着洗衣机的运转，开始供水循环。即，经供水管7和洗涤剂容器8引入混合有洗涤剂的洗涤水，从而充注旋转桶2的底部。当供给了和衣物量相应的希望的水量时，供水循环完成。供水循环完成后，驱动电机5与旋转轴5a一起以顺时针和逆时针方向交替旋转。因此，洗涤了旋转桶3中容纳的衣物。Thereafter, the user closes the door 6, and operates a control panel (not shown) to operate the washing machine. With the washing machine running, the water supply cycle begins. That is, wash water mixed with detergent is introduced through the water supply pipe 7 and thedetergent container 8 to fill the bottom of the rotary tub 2 . When a desired amount of water corresponding to the amount of laundry is supplied, the water supply cycle is completed. After the water supply cycle is completed, the drive motor 5 rotates clockwise and counterclockwise alternately together with therotating shaft 5a. Accordingly, the laundry contained in therotary tub 3 is washed.

尽管在洗涤循环过程中相对大量的衣物位于旋转桶3的后端部分，由于其具有其后端部分比其前端部分较高的高度，提升器20可以毫无问题地提升起衣物，从而有效地洗涤衣物。此外，旋转桶3可以在动态平衡状态下旋转。Although a relatively large amount of laundry is located at the rear end portion of therotary tub 3 during the washing cycle, since it has a higher height of its rear end portion than its front end portion, thelifter 20 can lift the laundry without any problem, thereby effectively Wash clothes. In addition, therotary barrel 3 can rotate in a dynamic equilibrium state.

当提升器20提升衣物按照旋转桶的旋转，连续移动到与旋转桶3的顶部连接的水平面时，衣物被从提升器20释放，然后抛下，从而被洗涤。同时，通过在旋转桶3的底端的提升器的底部22引入混合有洗涤剂的洗涤水，然后通过在提升器20的顶部21提供的喷水孔23向下喷洒，从而浸入衣物。When the lifter 20 lifts the laundry to continuously move to a level connected to the top of therotary tub 3 according to the rotation of the rotary tub, the laundry is released from thelifter 20 and then dropped to be washed. Meanwhile, washing water mixed with detergent is introduced through the bottom 22 of the lifter at the bottom end of therotary tub 3, and then sprayed downward through the water spray holes 23 provided at the top 21 of thelifter 20, thereby soaking into the clothes.

此时，由于分别具有大约相等体积的第一至第三室41至43在提升器20的内部通过第一和第二分隔板31和32是相互分离的，因此，洗涤水不从提升器20的前端部分流向其后端部分。At this time, since the first tothird chambers 41 to 43 respectively having approximately equal volumes are separated from each other by the first andsecond partition plates 31 and 32 inside thelifter 20, the wash water does not flow from thelifter 20. The front portion of 20 flows to its rear portion.

即，容纳在第一室41的洗涤水只通过形成于提升器20前端部分的喷水孔23喷洒，而容纳在第二室42的洗涤水只通过形成于提升器20的中间部分的喷水孔23喷洒。同样，容纳在第三室43中的洗涤水只通过形成于提升器20的后端部分的喷水孔23喷洒。That is, the wash water contained in thefirst chamber 41 is sprayed only through thespray hole 23 formed at the front end portion of thelifter 20 , and the wash water contained in thesecond chamber 42 is sprayed only through thespray hole 23 formed at the middle portion of thelifter 20 .Hole 23 sprays. Also, the wash water contained in thethird chamber 43 is sprayed only through thewater spray hole 23 formed at the rear end portion of thelifter 20 .

因此，洗涤水可以在提升器的整个长度上均匀地喷洒。从而，混合有洗涤剂的洗涤水不仅充分地喷洒在位于旋转桶3后端的衣物上，而且充分喷洒在位于旋转桶3中部和前端的衣物上，因此所有部分的衣物被洗涤水均匀浸湿。Therefore, wash water can be evenly sprayed over the entire length of the lifter. Thus, the washing water mixed with detergent is fully sprayed not only on the clothes at the rear end of therotary tub 3, but also on the clothes at the middle and front of therotary tub 3, so that all parts of the clothes are evenly wetted by the washing water.

洗涤循环完成后，通过漂洗和脱水循环将衣物漂洗干净并甩干。因此，完成衣物的洗涤。在漂洗循环中，根据第一和第二分隔板31和32的功能和效果，所有的衣物也可以被均匀地漂洗。After the wash cycle is complete, rinse and spin dry the laundry with the rinse and spin cycle. Thus, the washing of the laundry is completed. In the rinsing cycle, according to the functions and effects of the first andsecond partition plates 31 and 32, all the laundry may also be evenly rinsed.

衣物的洗涤完成后，用户再次打开门6，并从旋转桶3中取出衣物。此时，由于旋转桶3向上倾斜，用户可以不用太弯腰就可以方便地进行这些操作。After the washing of the clothes is completed, the user opens the door 6 again and takes out the clothes from therotary tub 3 . At this time, since therotating barrel 3 is inclined upward, the user can conveniently perform these operations without bending too much.

图6至8分别表示根据本发明另一实施例的提升器的结构。图6表示排列在旋转桶的内部表面上的提升器。图7表示在其顶部具有波形表面的提升器。图8表示排列在提升器内部的分隔板。6 to 8 respectively show the structure of a lifter according to another embodiment of the present invention. Figure 6 shows lifters arranged on the inner surface of the rotating tub. Figure 7 shows a riser with a corrugated surface at its top. Figure 8 shows the divider panels arranged inside the riser.

参照图6和7，除了其表面即其顶部21具有包括交替排列并分别具有圆弧表面的凹槽和凸起的波形结构外，提升器20a具有与图3中所示的提升器相似的结构。Referring to FIGS. 6 and 7, except that its surface, that is, its top 21 has a corrugated structure including grooves and protrusions arranged alternately and respectively having arcuate surfaces, the lifter 20a has a structure similar to that of the lifter shown in FIG. 3 .

即，提升器20a的顶部21具有向着旋转桶3的前端逐渐减小的高度的倾斜结构。脊部21a和槽底21b也在提升器21a的顶部21上以一定的间距交替排列。此外，在波形顶部21上提供了喷水孔23从而纵向地排列为几行。在各行中相应的喷水孔在各脊部21a和各槽底21b中横向地排列。That is, the top 21 of the lifter 20 a has an inclined structure with a gradually decreasing height toward the front end of therotary tub 3 . Ridges 21a and groove bottoms 21b are also arranged alternately at a certain interval on the top 21 of the lifter 21a. In addition, water spray holes 23 are provided on the corrugated top 21 so as to be longitudinally arranged in several rows. Corresponding spray holes in each row are arranged laterally in each ridge 21a and each groove bottom 21b.

由于提升器在其顶部21上具有包括脊部21a和槽底21b的波形结构，引入提升器20a内部的洗涤水停留在提升器20a的内部由脊部21a所限定的空间中，而不会立即从提升器20a的前端部分流向其后端部分，并通过喷水孔23向着旋转桶3的底部连续地喷洒。因此，即使在提升器20a的前端部分也有足够量的洗涤水可以喷洒。Since the lifter has a wave structure including ridges 21a and groove bottoms 21b on its top 21, the wash water introduced into the inside of the lifter 20a stays in the space defined by the ridges 21a inside the lifter 20a without immediately It flows from the front end portion of the lifter 20 a to its rear end portion, and continuously sprays toward the bottom of therotary tub 3 through thewater spray hole 23 . Therefore, a sufficient amount of wash water can be sprayed even at the front end portion of the lifter 20a.

另外，由于喷水孔23沿着脊部21a和槽底21b按行纵向地排列，还没有通过处于比另一脊部21a高的水平面的喷水孔23被排出的洗涤水，流向下一个水平的脊部21a，并通过下一个水平面的脊部21a的喷水孔23排出。In addition, since the water spray holes 23 are longitudinally arranged in rows along the ridge 21a and the groove bottom 21b, the wash water that has not been discharged through the water spray holes 23 at a level higher than the other ridge 21a flows to the next level. ridge 21a of the next horizontal plane, and is discharged through thespray hole 23 of the ridge 21a of the next horizontal plane.

因此，洗涤水不会从提升器20a的前端立即流向其后端，从而不是被主要地只喷洒在提升器20a的后端。Therefore, the wash water does not immediately flow from the front end of the lifter 20a to the rear end thereof, so as not to be mainly sprayed only on the rear end of the lifter 20a.

由于提升器20a的顶部21具有波形结构，在旋转桶3以顺时针和逆时针交替旋转的过程中，摩擦力施加于衣物。Since the top 21 of the lifter 20a has a wave structure, frictional force is applied to the laundry during the rotation of therotary tub 3 alternately clockwise and counterclockwise.

同时，如图8中所示，提升器20a可包括：在其顶部21上的圆弧形脊部21a和圆弧形槽底21b，同时还包括在其内部的分隔板，例如，图4和5的分隔板31和32。Meanwhile, as shown in FIG. 8, the lifter 20a may include: a circular arc-shaped ridge 21a and a circular arc-shaped groove bottom 21b on its top 21, while also including a partition plate inside it, for example, FIG. 4 and 5partition plates 31 and 32.

采用提升器20a的这种结构，在提升器20a中接收的洗涤水主要停留在由脊部21a在提升器20a的内部所限定的空间中，减慢了洗涤水从而向着提升器20a的较低水平面部分的流动。此外，由于第一和第二分隔板31和32，洗涤水不再流向提升器20a的较低水平面部分。因此，可以更有效地防止洗涤水从提升器20a的前端部分流向其后端部分。With this structure of the lifter 20a, the wash water received in the lifter 20a mainly stays in the space defined by the ridge 21a inside the lifter 20a, slowing down the wash water so as to flow toward the lower portion of the lifter 20a. Flow in the horizontal section. In addition, due to the first andsecond partition plates 31 and 32, the wash water no longer flows to the lower level portion of the lifter 20a. Therefore, it is possible to more effectively prevent wash water from flowing from the front end portion of the lifter 20a to the rear end portion thereof.

从上述的描述显然可知，在根据本发明的一方面的滚筒式洗衣机中，旋转桶向着壳体的前壁向上地倾斜，从旋转桶的内部外围表面突出的每个提升器具有当其位于旋转桶的最低水平面时其顶部维持水平的结构。因此，即使当相对大量的衣物分布于旋转桶的后端部分时，也可能毫无问题地提升衣物，从而快速并有效地洗涤衣物。As apparent from the above description, in the drum type washing machine according to an aspect of the present invention, the rotary tub is inclined upward toward the front wall of the housing, and each lifter protruding from the inner peripheral surface of the rotary tub has a The lowest level of the bucket is when its top maintains a horizontal structure. Therefore, even when a relatively large amount of laundry is distributed in the rear end portion of the rotary tub, it is possible to lift the laundry without any problem, thereby washing the laundry quickly and efficiently.

由于在根据本发明的滚筒式洗衣机中的这种结构，可通过提升器稳定地提升衣物。因此，旋转桶可在动态稳定的状态下旋转。Due to this structure in the drum type washing machine according to the present invention, laundry can be stably lifted by the lifter. Therefore, the rotary tub can rotate in a dynamically stable state.

另外，衣物不会缠绕或结块。因此，在脱水过程中旋转桶在平衡状态下旋转。也没必要将被洗涤的衣物解开缠绕。Plus, laundry won't tangle or clump. Therefore, the rotary tub rotates in a balanced state during the dehydration process. There is also no need to untangle the laundry being washed.

在根据本发明的另一方面的滚筒式洗衣机中，分隔板被排列于每个提升器中，以在提升器的内部限定分别具有大约相等容积的室。由于这种结构，混合有洗涤剂的洗涤水可以在提升器的整个长度上均匀的喷洒。因此，快速地并有效地洗涤甚至分布在位于相对高的水平面的旋转桶的前端部分的衣物成为可能。In a drum type washing machine according to another aspect of the present invention, a partition plate is arranged in each lifter to define chambers respectively having approximately equal volumes inside the lifter. Due to this structure, the washing water mixed with detergent can be evenly sprayed over the entire length of the lifter. Therefore, it becomes possible to quickly and efficiently wash even the laundry distributed at the front end portion of the rotary tub located at a relatively high level.

在根据本发明的另一方面的滚筒式洗衣机中，每个提升器在其顶部具有波形结构。喷水孔在波形结构的脊部和槽底中按行排列。只使用这种结构或与多个分隔板一起使用，在提升器的整个长度上均匀地喷洒混合有洗涤剂的洗涤水，同时对衣物施加摩擦力是可能的。因此，可以更快和更有效地洗涤衣物。In the drum type washing machine according to another aspect of the present invention, each lifter has a wave structure at its top. The water spray holes are arranged in rows in the ridges and groove bottoms of the corrugated structure. Using this structure alone or in combination with a plurality of partition plates, it is possible to uniformly spray wash water mixed with detergent over the entire length of the lifter while applying friction to the clothes. Therefore, laundry can be washed more quickly and efficiently.

尽管已表示和描述了本发明的一些实施例，但是本领域的技术人员应该理解，在不脱离本发明的原理和精神，以及由权利要求和其等同物所限定的范围的情况下，可对实施例进行改动。Although some embodiments of the present invention have been shown and described, it should be understood by those skilled in the art that, without departing from the principle and spirit of the present invention and the scope defined by the claims and their equivalents, the Examples are modified.
