Operation according to the vacuum cleaner with wet method cleaning function and said structure 1 of the embodiment of the invention is described in detail with reference to Fig. 1 to 9.

At first, will the situation of carrying out wet cleaning according to the vacuum cleaner 1 of the embodiment of the invention be described.

When carrying out wet cleaning, power turn-on switch 15, the mode switch 16 of handle 11 is switched to the wet cleaning pattern.Like this, switch pump 17 closes, water is discharged to the front ofbrush assembly 20 from two draining nozzles 74.When switch pump 17 closes, air pump 72 operations.Air pump 72 will mix from the water and air of water supply hose 71 and discharge by scupper hose 73.Like this, the water that mixes with air is discharged by two draining nozzles 74.At this moment, water or air alternately flow in scupper hose 73.Therefore, when air pump 72 operations, water is discharged continuously.Yet when air pump 72 stopped, the air in thescupper hose 73 prevented that water from flowing, thereby remaining water can be prevented from discharging by drainingnozzle 74 between drainingnozzle 74 and the air pump 72.Necessary, the discharge rate that can regulate air pump 72 is suitably to control the water yield of discharging by drainingnozzle 74.

When water was discharged on theclean surface 2 ofbrush assembly 20 fronts, the user moved forward and backwardbrush assembly 20 with handle 11.Like this, 62 operations of the motor of preceding andback stop member 40 and 50, motor sub-assembly and the motor of brush unit 60 have the water of dirt and are collected in the dirt collection vessel with suction.

Operation with before describing in detail and backstop member 40 and 50.

Whenbrush assembly 20 was positioned on theclean surface 2, bottom 41b, the 52b of preceding and backstop member 40,50 was because of the deadweight pressurized of brush assembly 20.Whenbrush assembly 20 when first direction A moves forward,rotation projection 43 contacts withclean surface 2, precedingstop member 40 is rotated counterclockwise (direction among Fig. 8 shown in the arrow C) based on rotating shaft 42.Like this, the number of degrees thatcurrent stop member 40 rotates increase when tight, the bottom 41b ofbarrier plate 41 and the increase of the interval between the clean surface 2.When aside 44 ofrotation projection 43 was vertical withclean surface 2 as shown in Figure 8, owing to the bottom 41b ofbarrier plate 41 is positioned at the highest position, the anteriordirt suction passage 3 of the front ofdirt suction inlet 22 was opened fully.Whenbrush assembly 20 when first direction A moves forward, back stop member 50 has the back barrier plate 52 to the rear side bending of brush assembly 20.Because theflat surface 53 of back barrier plate 52 is positioned at the front portion, the rear portiondirt suction passage 4 ofdirt suction inlet 22 is blocked.Therefore, can prevent that dirt from sucking from the rear portion of dirt suction inlet 22.As mentioned above, whenbrush assembly 20 when first direction A moves forward, anteriordirt suction passage 3 is opened by precedingstop member 40, and rear portiondirt suction passage 4 is stopped up by back stop members 50.Therefore, the water that has air that can suck wet dirt effectively and be discharged tobrush assembly 20 fronts according to the vacuum cleaner of the embodiment of the invention.

As user during along the backwardmobile brush assembly 20 of second direction B,rotation projection 43 contacts with clean surface 2 (referring to Fig. 9), and precedingstop member 40 is based on rotatingshaft 42 turn clockwise (direction shown in the arrow D among Fig. 9).Along with the increase of degree of rotation, the bottom 41b ofstop member 41 becomes lower, to stop up anterior dirt suction passage 3.As shown in Figure 9, whenbarrier plate 41 andclean surface 2 were vertical, anteriordirt suction passage 3 was blocked fully.Whenbrush assembly 20 when second direction B moves forward, back stop member 50 has the back barrier plate 52 to the front curvature of brush assembly 20.At this moment, because back barrier plate 52 hasprotrusion surface 54 at rear side, the rear portion ofdirt suction inlet 22 is communicated withdirt suction inlet 22 fluid ground by the space 56 between a plurality of projections 55 of protrusion surface 54.Therefore, rear portiondirt suction passage 4 is opened.As mentioned above, when mobile backward, althoughbrush assembly 20 moves forward, dust catcher 1 main the suction also removed water remaining on theclean surface 2 tobrush assembly 20 along second direction B.

When power switch 15 closes, 62 rotations of brush motor.When brush motor 62 rotation,brush 61 is accepted by pulley 64 and 65 and the revolving force and the rotation of the brush motor 62 that transmits of conveyer belt 66 (referring to Fig. 3).When brush 61 rotations,bristle 61b rotation, the wet dirt of self-cleaning surface 2 is come on wipedclean surface 2 with effective removal.Becausebristle 61b is the structure of circular arc, is the shape of spill such as the direction of rotation E along brush 61 (referring to Fig. 4), therefore dirt and the water of removing from the clean surface can be advanced to thedirt suction inlet 22 effectively.

As mentioned above, along with moving forward or backward ofbrush assembly 20, front and reardirt suction passage 3 and 4 is opened or stopped up to precedingstop member 40 and back stop member 50 selectively, andbrush 61 rotations, wipedclean surface 2 is so dirt and water can 2 removings from the clean surface effectively.

Next, the situation when describing vacuum cleaner 1 according to the embodiment of the invention and carry out common cleaning.

The user switches to common cleaning mode with the mode switch 16 of handle 11.Like this, when pressing power switch, the operation of the motor sub-assembly of main body 10 has produced suction like this.The dirt that comes self-cleaning surface 2 is inhaled into the dirt suction inlet 22 of brush assembly 20 and is collected in the dirt collection vessel under the effect of suction.At this moment, brush motor 62 also starts, and is used to rotate the brush 61 of dirt suction inlet 22.In other words, the dirt according on the vacuum cleaner 1 suction clean surface 2 of the embodiment of the invention cleans with the same with general vacuum cleaner.Yet only difference is that preceding and back stop member 40,50 is operated when brush assembly 20 is mobile forward or backward selectively.Specifically, when brush assembly 20 when first direction A moves forward, preceding stop member 40 rotates to an angle, to open anterior dirt suction passage 3, and back barrier plate 52 is along the opposite direction bending of dirt suction inlet 22, to stop up rear portion dirt suction passage 4.On the contrary, when brush assembly 20 is mobile backward along second direction B, before stop member 40 along rotating to an angle in the opposite direction stopping up anterior dirt suction passage 3 with above-mentioned side, and back barrier plate 52 is used to open rear portion dirt suction passage 4 to 22 bendings of dirt suction inlet.

In addition, ifbrush body 21 has ultraviolet lamp 90 at basal surface, along with moving ofbrush assembly 20, because ultraviolet ray can be radiated on theclean surface 2,clean surface 2 can be sterilized.

Although the present invention is illustrated and describes with reference to some embodiment, yet those skilled in the art will appreciate that and to carry out the change of various forms and details to the present invention, and do not break away from of the present invention as spirit and scope that claim limits.
