With reference to Fig. 3 and Fig. 4, cleaning brush 33, cleaning brush 33 is located at position corresponding with chute 311 on slide block 32, and cleaning brush 33 from chute 311 stretch out and with the contact internal walls of urceolus 2, wherein, realizing cleaning brush 33 has multiple from the mode that chute 311 stretches out, such as: position corresponding with chute 311 on slide block 32 arranges connector (not shown), described connector stretches out chute 311, and cleaning brush 33 is fixed on described connector, and described connector can be one-body molded with slide block 32; Or being directly fixed on by cleaning brush 33 is positioned on the slide block 32 of column 31, cleaning brush 33 is through after chute 311 and the contact internal walls of urceolus 2.
In addition, the mode be fixed on by column 31 on the sidewall of inner core 1 specifically can be: be fixed on the outer wall of inner core 1 by column 31 by welding, the bonding or mode such as to be threaded, water inlet 312 is between inner core 1 and urceolus 2, or can column 31 be fixed on the inwall of inner core 1 by welding, the bonding or mode such as to be threaded, and opening (not shown) is offered in position corresponding with column 31 on inner core 1, cleaning brush 33 stretches out the contact internal walls with urceolus 2 after chute 311 and described opening.
Operationally, described impeller and inner core 1 rotate with contrary direction, column 31 rotates along with inner core 1, current in urceolus 2 can tangentially enter water inlet 312 along inner core 1, the current entering water inlet 312 upwardly slide block 32 in column 31, slide block 32 drives cleaning brush 33 to move up along chute 311, due to cleaning brush 311 and urceolus 2 contact internal walls, thus in the process of rotating along with inner core 1, upwards can clean urceolus 2 inwall, when inner core 1 rotates backward, current also reverse immediately, namely current dorsad water inlet 312 flow, hydraulic pressure in column 31 declines, density due to slide block 32 is greater than the density of water, slide block 32 can move down under the effect of self gravitation, cleaning brush 33 is driven to clean the inwall of urceolus 2 downwards, thus by the rotating with inner core 1 that moves up and down of cleaning brush 33, clean the inwall of urceolus 2, soak with cleaning agent and current flushing compared to simple, cleaning brush 33 is directly exerted pressure to the inwall of urceolus 2, thus scrub effect is better, and utilize the rotation of inner core 1 can realize cleaning, do not need extra power source, the cleaning to described outer tube inner wall can be realized while washing, thus special cleaning need not be carried out again, save the time of user.Thus, achieve the automatic cleaning to outer tube inner wall, meanwhile, improve the cleaning performance to outer tube inner wall.
With reference to Fig. 3, slide block 32 can be solid construction or hollow structure, if but slide block 32 is entity structure, then weight is large compared with hollow structure, is unfavorable for that current are by slide block 32 jack-up, therefore, for the ease of current by slide block 32 jack-up, slide block 32 can be hollow structure, and the upper end closed of slide block 32, lower end is provided with opening 321, opening 321 is communicated with water inlet 312, make current can enter the inside of slide block 32, expand the contact surface of current and slide block 32, be conducive to slide block 32 jack-up.
Because slide block 32 moves up and down in the hollow structure of column 31, therefore, the length of slide block 32 in the vertical direction is less than the length of the hollow structure in the vertical direction of column 31, and the width of column 31 internal chute 311 can be made to be less than the width of slide block 32, the width of chute 311 is mated with the width of cleaning brush 33, thus meet under cleaning brush 33 stretches out chute 311 condition, the width of chute 311 is minimized, after reducing slide block 32 rising, from the current that chute 311 overflows, thus improve current to the active force of slide block 32, also can deviate from from chute 311 by anti-limited slip block 32, simultaneously, the outer wall of slide block 32 and the inwall of column 31 also can be made to fit, prevent current from flowing from the gap between the outer wall of slide block 32 and the inwall of column 31, current are maximized the active force of slide block 32.
With reference to Fig. 2 and Fig. 4, rotary drum washing machine described in the present embodiment is when dewatering, water in urceolus 2 is drained, inner core 1 rotates, thus the clothing in inner core 1 is dried, now, if cleaning brush 33 still with the contact internal walls of urceolus 2, owing to there is no water in urceolus 2, cleaning brush 33 can produce noise with the inwall of urceolus 2 because of friction, therefore, baffle plate 34 can be set in the lower end frame of chute 311, baffle plate 34 is fixedly connected with column 31 or one-body molded, between the inwall of baffle plate 34 and urceolus 2, there is gap, when slide block 32 drops to the extreme lower position in column 31, cleaning brush 33 drops to the position corresponding with baffle plate 34 and is extruded covering by baffle plate 34, separated with the inwall of urceolus 2 and cleaning brush 33 by baffle plate 34, now, baffle plate 34 intercepts between cleaning brush 33 and the inwall of urceolus 2, make when dewatering, cleaning brush 33 does not contact with the inwall of urceolus 2, thus prevent from producing noise when dewatering because of wall friction in cleaning brush 33 and urceolus 3.
Concrete, cleaning brush 33 can adopt various ways, such as: described cleaning brush can be loop configuration (not shown), the loop configuration of described cleaning brush is set in beyond the entirety of described column and the formation of described inner core, the position that the inner side of described cleaning brush is corresponding with described chute is connected with described slide block, the external diameter of this loop configuration and the diameter matches of described outer tube inner wall, make the contact internal walls of the outside of described cleaning brush and described urceolus, the cleaning brush of described loop configuration can be moved up and down with described slide block, thus the cleaning completed described outer tube inner wall, further also, can in this ring type structure, outer both sides all arrange bristle (not shown), the bristle of inner side and the wall contacts of described inner core, the bristle in outside and the contact internal walls of described urceolus, thus not only can clean described outer tube inner wall but also described inner tank theca can be cleaned, or cleaning brush 33 can be and is directly fixed on region corresponding with chute 3 on slide block 32, namely cleaning brush 33 entirety is the bar shaped matched with chute 311, the cleaning brush size of loop configuration is larger, when material is identical, its weight is also larger, thus may there is hydraulic pressure is not enough to the situation of the cleaning brush jack-up of loop configuration, or the height of jack-up is lower, be difficult to the inwall fully cleaning urceolus, therefore, cleaning brush 33 preferably adopts the strip structure matched with chute 311, and be directly fixed on region corresponding with chute 3 on slide block 32, to ensure that cleaning brush 33 can normally rise.
Concrete, cleaning brush 33 can embed slide block 32, thus is fixed on slide block 32, also can be adhered on slide block 32 by adhesive.
Flow for the ease of guiding on current direction, position that can be relative with water inlet 312 in column 31 arranges an inclined-plane 313, inclined-plane 313 away from one end of water inlet 312 higher than near one end of water inlet 312, after current enter water inlet 311 and inclined-plane 313 collides, and upwards flow, current can be avoided to enter water inlet 312 inwall collision rift that is rear and column 31 rebound to water inlet 312, thus be conducive to current further by slide block 32 jack-up.
In order to ensure that current have enough thrust by slide block 32 jack-up to slide block 32, in the vertical direction, the lower end of chute 311 can be made higher than water inlet 312, thus can prevent current from namely flowing out from chute 311 at the beginning of entering water inlet 312, hydraulic pressure is reduced, be unfavorable for slide block 32 jack-up, thus ensure that current can not flow out after entering column 31 immediately, be conducive to ensureing that slide block 32 can normally rise.
With reference to Fig. 1, in order to improve cleaning performance, multiple cleaning device 3 can be set, and multiple cleaning device 3 can be made to be uniformly distributed along the circumference of inner core 1, be cleaned by the inwall of multiple cleaning devices 3 pairs of urceolus 2, remove the spot on the inwall of urceolus 2 better.
Wherein, the water inlet 312 of multiple cleaning device 3 can simultaneously along clockwise tangential or counterclockwise tangential towards urceolus 2, according to this kind of structure, operationally, the water inlet 312 of each cleaning device 3 can simultaneously in face of water movement or water movement dorsad, and thus slide block 32 can rise simultaneously or decline; Or part water inlet 312 is along clockwise tangential towards urceolus 2, another part water inlet 312 is along counterclockwise tangential towards urceolus 2, and according to this kind of structure, operationally, part slide block 32 rises, and another part slide block 32 declines.
Because described impeller is positioned at the bottom of inner core 1, described impeller is larger for the active force of these place's current, the kinetic energy making current is herein comparatively large, can maximum jack-up slide block 32, therefore, the one end that column 31 can be made to be provided with water inlet 312 is positioned at the bottom of inner core 1 outer wall, when entering water inlet 312, by slide block 32 farthest jack-up, thus the stroke of cleaning brush 33 can be extended when current and water inlet 312 relative motion, be conducive to expanding clean range, improve cleaning performance.
In order to avoid because slide block 32 is caused the scouring scope of cleaning brush 33 to reduce by the height of jack-up deficiency further, with reference to Fig. 5, the second embodiment of Fig. 5 position rotary drum washing machine provided by the invention, specifically please refer to the first embodiment above-mentioned, unlike, in second in embodiment, cleaning device 3 comprises the first cleaning device 3a and the second cleaning device 3b, first cleaning device 3a is substantially identical with the structure of the second cleaning device 3b, first cleaning device 3a comprises: column 31a, slide block 32a and cleaning brush 33a, column 31a is provided with the chute 311a vertically extended, water inlet 312a is provided with bottom column 31a, in column 31a, the position relative with water inlet 312a arranges an inclined-plane 313a, second cleaning device 3b comprises: column 31b, slide block 32b and cleaning brush 33b, column 31b is provided with the chute 311b vertically extended, water inlet 312b is provided with bottom column 31b, in column 31b, the position relative with water inlet 312b arranges an inclined-plane 313b, detailed construction and principle are with reference to above-mentioned first kind of way, wherein, with reference to Fig. 6 and Fig. 8, in the vertical direction, chute 311a lower end in first cleaning device 3a and the distance between water inlet 312a are greater than the distance of chute 311b lower end in the second cleaning device 3b and water inlet 312b, and with reference to Fig. 7 and Fig. 9, cleaning brush 33a in first cleaning device 3a is positioned at the upper end of slide block 32a, cleaning brush 33b in second cleaning device 3b is positioned at the lower end of slide block 32b, that is, the extreme lower position of the slide block 32a of the first cleaning device 3a is higher than the extreme lower position of the slide block 32b of the second cleaning device 3b, during work, current enter column 31a by water inlet 312a, column 31b is entered by water inlet 312b, when hydraulic pressure deficiency, the distance that cleaning brush 33a and cleaning brush 33b can rise is limited, now, because the distance between chute 311a lower end and water inlet 312a is greater than the distance of chute 311b lower end and water inlet 312b, make cleaning brush 33a can increase from higher position, cleaning brush 33b can rise from lower position, the upper section of 33a urceolus 2 capable of washing inwall, the lower part of cleaning brush 33b urceolus 2 capable of washing inwall, thus can when hydraulic pressure is less, namely hydraulic pressure only can make slide block 32a rise comparatively short distance, can ensure all can realize cleaning to the upper and lower of the inwall of urceolus 2.
