Abstract

The utility model relates to a device for cleaning fouling between an internal cylinder and an external cylinder of a washing machine. A radial slide groove is arranged on the outer bottom surface of the bottom of the internal cylinder. A movable slide block is arranged in the slide groove. The slide block is provided with brush hair pointing to the inner bottom surface of the external cylinder. The brush hair can be located close to the center contacting with the inner bottom surface of the external cylinder and can also be located away from the center separating from the inner bottom surface of the external cylinder. When in washing, the brush hair is relatively still to the inner bottom surface of the external cylinder. When in water splash, the brush hair and the inner bottom surface of the external cylinder transmit quickly from the state of contact to that of separation in accompany with relative movement towards each other. Thus the utility model realizes cleaning fouling, and at the same time, the brush hair is unlikely to be worn heavily so that the device is provided with long service life.

Description

The washing machine automatic cleaning apparatus

Technical field

The utility model relates to the washing machine field, specifically is the dirt removal device between the inside and outside bucket of washing machine.

Technical background

Washing machine be Modern Family life than the domestic electric appliances product that is equipped with, its effect is conspicuous, promptly it helps people to be engaged in to free in the loaded down with trivial details home laundry, bring many convenience to people.Washing machine in use for some time, accumulation has dirt between inside and outside bucket, this residual dirt is among the moist environment for a long time, causes the breeding of bacterium easily, have in addition give off an unpleasant smell.Like this,, can cause the secondary pollution when doing washing inevitably, thereby influence people's health if can not in time remove.

Technology contents

The purpose of this utility model provides the healthy washing machine of a kind of self-cleaning, in time removes the dirt of retaining in the washing machine course of work automatically by set cleaning device.

For achieving the above object, the technical solution adopted in the utility model is: a kind of washing machine automatic cleaning apparatus, it is characterized in that: the outer bottom at the bucket end of washing machine inner tub is provided with the chute of radially arranging, chute inside is provided with transportable slide block within it, slide block is provided with the bristle of the inner bottom surface that points to outer bucket, and above-mentioned bristle can be near the inner bottom surface contact of center position and outer bucket and be in away from center position and separate two states with the inner bottom surface of outer bucket.

As shown from the above technical solution, bristle is placed in the outside of washing machine inner tub bottom, and can be in contact and separate two states with the inner bottom surface of outer bucket, promptly when washing usually, bristle is relative static with the inner bottom surface of outer bucket, and both separate rapid transition towards each other from contacting and being accompanied by to relatively move when dehydration, thereby have realized the purpose with soil release, simultaneously be unlikely to the heavy wear bristle again, make device have long service life.

The utility model mainly is to be used for removing the inner accumulation dirt of the washing machine course of work, the secondary pollution when avoiding doing washing, and it can in time remove the dirt of retaining in the washing machine course of work automatically, guarantees the cleaning of washing machine self.

The specific embodiment

Embodiment 1

Referring to 1,2, the outer bottom at the bucket end 11 of washing machine inner tub 10 is provided with the chute of radially arranging 20, chute 20 inside are provided with transportable slide block 30 within it, slide block 30 is provided with the bristle 40 of the inner bottom surface that points to outer bucket, and above-mentioned bristle 40 can be near inner bottom surface 51 contacts of center position and outer bucket 50 and be in away from center position and separate two states with the inner bottom surface 51 of outer bucket 50.

It is high that described slide block 30 is in the level height summary of being partial to center position than being in the external position place, is provided with back-moving spring 60 between described chute 20 and the slide block 30.One end of back-moving spring 60 links to each other with slide block 30, and the other end is fixed on the centre of gyration place near interior bucket 10.

Described chute 20 is along having the upward to setting of an angle with level, and the about two ends of described chute 20 have been provided with the block of position-limiting action.The cross section of described chute 20 be T or , shown in Fig. 9 or 10.

Below sketch operation principle of the present utility model:

Interior bucket 10 inactive states, initial action because of back-moving spring 60, back-moving spring 60 among Fig. 1, Fig. 2 is the extension spring structure, bristle 40 is keeping contacting with outer bucket 50 bottom interior surfaces, when washing machine is in the washing duty, interior bucket 10 does not rotate, no additional radial active force, and bristle 40 is static does not relatively work; When washing machine is in the dehydration duty, bristle 40 rotates with interior bucket, centrifugal force is radially had an effect, this active force improves and increases along with rotating speed, when rotating speed is low, as to design the control rotating speed be 200rpm, contacts because of bristle 40 still has with outer bucket 50 surfaces, automatically the dirt that precipitates of cleaning.Usually outer bucket 51 water discharge outlet positions, 50 bottom surfaces are concave shape, and dirt cleaned through bristle 40, concentrate on water discharge outlet depression position, and dirt will flow out outside the drainpipe along with water afterwards like this.After the dehydration barrel rotating speed improves, because of centrifugal action, quality slide block 30 outwards moves along chute 20 together with bristle 40, back-moving spring 60 stress deformations increase, its active force and centrifugal force tend to balance, bristle 40 upwards promotes simultaneously along chute 20, and with outer bucket 50 surface isolation, thereby do not work, played the effect that takes out stains so on the one hand, guaranteed 40 service lifes of bristle and reliability simultaneously, avoided in addition under the situation of running up, the additional electrical energy loss that bristle 40 causes with contacting of outer bucket.Be decelerated to halted state when dehydration finishes, centrifugal force is gradually reduced to disappearance, and bristle 40 is subjected to back-moving spring 60 effects, gets back to the original state position automatically.

Embodiment 2

Referring to Fig. 3,4, the present embodiment difference from Example 1 is that an end of back-moving spring 60 links to each other with slide block 30, back-moving spring 60 is a stage clip, and the other end is fixed on the outer rim bucket wall place near interior bucket 10, also is provided with at the about two ends of chute 20 to be used for

spacing block

21,22.

Embodiment 3

Referring to Fig. 5,6, described chute 20 is horizontal near the stroke of center, near deep outer end the upwards lifting section 23 of lifting is arranged, its bottom is provided with permanent magnet 231, be used to produce slide block 30 the suction-combining forces to making with ferrimagnet, the about two ends of described chute 20 can be provided with

positive stop

21,22 referring to embodiment 2.The cross section of described chute 20 can be referring to embodiment 1.

For interior, the washing machine that the outer barrel bottom spacing dimension is less, can adopt Fig. 7, the structure that provides in 8, the outer end of the slide block 30 that links to each other with bristle 40 is connected with a flexible cable 70, it walks around runner 80, after 90sly link to each other with centrifugal slider 100, slide block 100 is positioned at chute 110, back-moving spring 60,120 effect be with bristle 40 keep when the original state with outside barrels 50 inner bottom surface 51 contact, when interior bucket 10 dehydrations are rotated, under centrifugal action, overcome back-moving spring 60,120 elastic force, bristle 40 all moves and separates with outer bucket 50 in the bucket wall place of inside bucket 10 with slide block 100, and when rotating speed lowered, bristle 40 and slide block 100 resetted again.
