Description
Technical field
The present invention relates to washing machine field, specifically automatic washing machine, especially a kind of interior bucket has the automatic washing machine of the function that is filled with water.
Background technology
Traditional pulsator washing machine, as it is shown in figure 1, generally comprise the impeller 1 ' set gradually from the inside to the outside, interior bucket 2 ', outer barrel 3 ' and casing 4 ', wherein, impeller 1 ' is arranged on the bottom center of interior bucket 2 ' and can be rotated by driving device 5 '. Being provided with balance ring 6 ' on the top of interior bucket 2 ', 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 driving device 5 ' 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 discharge outlet 7 ', air chamber 31 ' and level sensor are used 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, drain valve 8 ' is closed, water inlet is in interior bucket 2 ', current be full of in bucket 2 ' time, also the dewatering hole 21 ' on interior bucket 2 ' sidewall and be full of whole outer barrel 3 ', that is, between outer barrel 3 ' bottom and interior bucket 2 ' bottom, be filled with water between outer barrel 3 ' sidewall and interior bucket 2 ' sidewall; By the water level in air chamber 31 ' and level sensor detection bucket, after water in bucket reaches designated water level, stop water inlet, washing machine starts washing, and specifically, driving device 5 ' drives impeller 1 ' reciprocating rotary, under the rotarily driving of impeller 1 ', water and medicated clothing in interior bucket 2 ' can roll therewith, medicated clothing phase mutual friction, and the medicated clothing simultaneously rolled produces friction repeatedly with the sidewall of impeller and interior bucket again and reaches the purpose washed; Wash complete, washing machine needs to discharge the current in bucket, then by clothes dewatering, specifically, during draining, open drain valve 8 ', current between outer barrel 3 ' and interior bucket 2 ' are successively by outside the discharge outlet 7 ' of outer barrel 3 ' bottom, drain valve 8 ', drain pipe 9 ' discharge casing 4 ', simultaneously, water in interior bucket 2 ' is discharged by dewatering hole 21 ' and is kept liquid level consistent with outer barrel 3 ', until current in bucket 2 ' flow downward in last, flow into outer barrel 3 ' from the spilled water hole 22 ' of interior bucket 2 ' bottom, then discharge from the discharge outlet 7 ' of outer barrel 3 ' bottom again; During dehydration, driving device 5 ' drives interior bucket 2 ' high speed rotating, moisture in medicated clothing is under the influence of centrifugal force, it is discharged to outer barrel 3 ' from the spilled water hole 22 ' of the dewatering hole 21 ' interior bucket 2 ' sidewall and bottom, then is discharged washing machine outer (consulting Fig. 1) by discharge outlet 7 ', drain pipe 9 '.
Due to existing pulsator washing machine, and this part water being full of between interior bucket and outer barrel sidewall is not involved in washing, the real water participating in washing is only the part in interior bucket, this makes water resource waste bigger, it addition, water too much between interior outer barrel also can reduce the concentration of detergent/detergent in cleaning mixture.
Meanwhile, owing to current frequently pass in and out between interior bucket, outer barrel, after persistently using, region between interior bucket and the sidewall of outer barrel has also become the space sheltered evil people and countenance evil practices, and dust and antibacterial that incrustation scale in tap water, the educt of detergent, the cellulose of medicated clothing, the Organic substance of human body and medicated clothing are brought into are very easily trapped between interior bucket and the sidewall of outer barrel. These mycetes are a large amount of dirts of the washing machine internal savings having used of a specified duration, grow breeding because can not effectively remove, if the dirt that these user be can't see not is removed, so after upper once washing, antibacterial can be attached to again on medicated clothing and bring human body, the problem causing cross infection.
Part manufacturer have developed barrel washing machine in a kind of atresia, and in namely, bucket has the function that is filled with water, and draining then utilizes interior bucket high speed rotating centrifugal force that from the apopore on interior bucket top, water is expelled to outer barrel, is then discharged out washing machine. As shown in Figure 3, this washing machine includes casing 1 ", be located at casing 1 " in outer barrel 2 "; be located at outer barrel 2 " in interior bucket 3 " and be located at interior bucket 3 " in impeller 4 ", wherein, outer barrel 2 " bottom be provided with drive in bucket 3 " and impeller 4 " driving device 5 that rotates "; Interior bucket 3 " for steel ladle, it is provided with apopore 6 on top ", meet when washing, the current of stirring can not from this apopore 6 " discharge.
Washing machine is started working, interior bucket 3 is arrived in water inlet " in, after water in interior bucket reaches suitable amount of water, stop water inlet, washing machine starts washing, specifically, driving device 5 " drive impeller 4 " reciprocating rotary, at impeller 4 " rotarily driving under, interior bucket 3 " in water and medicated clothing can roll therewith, medicated clothing phase mutual friction, the medicated clothing simultaneously rolled produces friction repeatedly with the sidewall of impeller and interior bucket again and reaches the purpose washed, wash complete, washing machine need by interior bucket 3 " in current discharge, then by clothes dewatering, specifically, driving device 5 " drive interior bucket 3 " in set point, improve rotating speed, interior bucket 3 " in water and water in medicated clothing rise through the apopore 6 on interior bucket top under the influence of centrifugal force along interior bucket spiral inner wall " be discharged to outer barrel 2 ", again by outer barrel 2 " discharge outlet 7 of bottom " discharge.
Although said structure has made improvement relative to conventional washer, water is not had between interior outer barrel, make interior bucket as steel ladle, overcome the defect of conventional washer so that improve washing machine and there is the feature of water saving, and owing to washings do not enter back between inside and outside bucket, avoid breed bacteria between interior outer barrel, the problem solving medicated clothing cross-contamination, but, there is also following defect: draining can only rely on bucket rotation in driving that water is discharged from top apopore, and water discharge time is long; It addition, in drainage procedure, it is necessary to driving device works, and power consumption is relatively high; Finally, using for a long time, deposition dirt such as sand grain etc. cannot be discharged, and saves bit by bit in interior bucket, saved bit by bit at most easily breed bacteria secondary pollution medicated clothing, and the parts worn and torn in medicated clothing or interior bucket even, such as impeller shafts seal member etc.
In view of this special proposition present invention.
