Description
Technical field
The present invention relates to washing machine field, specifically inner barrel structure of washing machine, hermetically-sealed construction at the bottom of especially a kind of washing machine inner tub.
Background technology
Existing pulsator washing machine, as shown in Figure 1, generally comprises the impeller 1 ' set gradually from the inside to the outside, interior bucket 2 ', outer barrel 3 ' and casing 4 ', wherein, impeller 1 ' be arranged on interior bucket 2 ' bottom center and can by drive unit 94 ' driven rotary.The top of interior bucket 2 ' is provided with gimbal 6 ', the sidewall of interior bucket 2 ' is vertically arranged with multiple row dewatering hole 21 ', interior bucket 2 ' bottom is provided with spilled water hole 22 ', and this spilled water hole 22 ' also supplies the output shaft 51 ' of drive unit 94 ' to run through simultaneously.As shown in Figure 2, outer barrel 3 ' sidewall bottom is provided with air chamber 31 ' and level sensor (not shown), top is provided with gap 32 ', bottom is provided with water discharge outlet 7 ', air chamber 31 ' and level sensor are for detecting outer barrel 3 ' water level, when gap 32 ' damages for level sensor, water inlet is too much discharged from this gap 32 '.
Washing machine is started working, draining valve 8 ' cuts out, in water inlet to interior bucket 2 ', current are when being full of interior bucket 2 ', also the dewatering hole 21 ' on interior bucket 2 ' sidewall and be full of whole outer barrel 3 ', also namely, outer barrel 3 ' bottom with interior bucket 2 ' bottom between, be all filled with water between outer barrel 3 ' sidewall and interior bucket 2 ' sidewall; The water level in bucket is detected by air chamber 31 ' and level sensor, after water in interior bucket 2 ' reaches designated water level, stop water inlet, washing machine starts washing, and particularly, drive unit 94 ' drives impeller 1 ' reciprocating rotary, under the rotarily driving of impeller 1 ', water in interior bucket 2 ' and clothing can roll thereupon, the mutual friction of clothing phase, and the clothing simultaneously rolled produces friction repeatedly with the sidewall of impeller and interior bucket and reaches the object of washing again; Wash complete, washing machine needs the current in bucket to discharge, then by clothes dewatering, particularly, during draining, open draining valve 8 ', current between outer barrel 3 ' and interior bucket 2 ' are discharged outside casing 4 ' by the water discharge outlet 7 ' bottom outer barrel 3 ', draining valve 8 ', drainpipe 9 ' successively, simultaneously, water in interior bucket 2 ' is discharged by dewatering hole 21 ' and is kept liquid level consistent with outer barrel 3 ', until the current direction current downflow in last in bucket 2 ', flow into outer barrel 3 ' from the spilled water hole 22 ' of interior bucket 2 ' bottom, and then discharge from the water discharge outlet 7 ' of outer barrel 3 ' bottom; During dehydration, bucket 2 ' High Rotation Speed in drive unit 94 ' drives, moisture in clothing under the influence of centrifugal force, be discharged to outer barrel 3 ' from the spilled water hole 22 ' of the dewatering hole 21 ' interior bucket 2 ' sidewall and bottom, then discharge washing machine outer (consulting Fig. 1) by water discharge outlet 7 ', drainpipe 9 '.
Due to existing pulsator washing machine, during laundry, all need between interior bucket and the sidewall of outer barrel to be full of water, therefore interior barrel structure does not need sealing, especially at the bottom of interior bucket, in order to Quick drainage, at the bottom of interior bucket and between interior bucket ring flange, also there is space, even ensure in the bottom strength basis on, can apopore be increased.But the rotary drum washing machine of this structure, this part water between interior outer barrel does not participate in washing, and the real water participating in washing is only the part in interior bucket, and this makes water resource waste larger, in addition, too much between interior outer barrel water also can reduce the concentration of washing agent/washing powder in cleaning solution.
Meanwhile, because current frequently pass in and out between interior bucket, outer barrel, after continuing to use, region between interior bucket and the sidewall of outer barrel has also become the space of sheltering evil people and countenance evil practices, and the dust that the incrustation scale in running water, the educt of washing powder, the cellulose of clothing, the organic matter of human body and clothing are brought into and bacterium are very easily trapped between interior bucket and the sidewall of outer barrel.These moulds be used washing machine internal savings of a specified duration a large amount of dirts, grow breeding because can not effectively remove, if the dirt that these users can't see will not be removed, so after upper once washing, bacterium can be attached on clothing again and bring human body, causes the problem of laundry cross infection.
In addition, because during washing of drum type washing machine, line bits swim in water, adopt existing drainage pattern, water is discharged from interior bucket bottom, finally can remain on clothing by line bits, affect laundry washing effects.
In view of this special proposition the present invention.
Summary of the invention
