The utility model relates to the field of a washing machine, in particular a clutch with a drainage structure and a water-saving washing machine. With a drainage structure of the clutch, including dewatering shaft, the dewatering shaft and the inner barrel of the washing machine through the flange, the sealing member is provided on the dewatering shaft, the sealing member is provided and is coaxial with the shaft in the dehydration dehydration shaft outside the seal for the hollow structure, seal the top and bottom respectively through the sealing ring and the sealing ring and the shaft is connected with a drainage dehydration; the sealing cavity is formed between the inner and the dewatering shaft, flange flange with drainage hole is arranged on the drainage channel between the drain hole and the drain flange cavity, the drainage in the side seal mouth, water outlet connected with the drain valve. The beneficial effect of the utility model is that it overcomes the problem that the drainage structure of the current water-saving washing machine is complex, the drainage components are much and the coaxality is difficult to guarantee, and at the same time, it also reduces the change of the washing machine structure, and is easy to reduce the production cost.

一种带有排水结构的离合器及节水洗衣机
本技术涉及洗衣机领域,具体地说是一种带有排水结构的离合器及节水洗衣机。
技术介绍
节水型套筒洗衣机,因为能够节水而受到广大消费者的欢迎。节水型洗衣机是仅在内桶中有水,而内桶和外桶形成的夹层中没有水;传统的套筒洗衣机是内外桶都有水,故节水型洗衣机能够实现节水。具体来说,传统的套筒洗衣机外桶与内桶是连通的,外桶上设有排水口及水位检测的气室,可以实现对水位的检测;而节水洗衣机是内桶是完全密封的,仅在内桶中有水,外桶中没有水,这种结构就会带来内桶储水、水位检测及排水时的困难。为了克服这一问题,市场上节水洗衣机的排水方式主要包括以下两种:一种是将排水结构做在外桶上,在内桶底部与离合器结合处做一个密封的金属环,外桶底部做一个排水腔和橡胶密封圈,将水部分引入到外桶的排水阀和气室,进行水位检测,并在洗涤完成后进行排水。这种结构优点是电器件通用、程序控制简单,其存在的问题是离合器装到外桶外部,橡胶密封圈装在外桶内部支撑的塑料件内,由于零件多,装配关系复杂,密封的金属环与外桶橡胶密封圈的同轴度难以保证,而同轴度偏差很容易超出橡胶密封圈所能容纳的偏差,导致密封圈的使用寿命缩短。同时由于密封圈直径很大,直径达80-120mm,其结构的固有缺陷也会带来整机可靠性差、生产困难等问题,因此这种排水结构虽然出现的时间较久,但迟迟没能推广。第二种排水方式是将内桶密封,内桶底部设有排水孔及定位装置。洗涤时,通过在外桶底部设置定位机构对内桶进行定位,同时通过外桶可伸缩阀体对内桶进行密封;在排水时,伸缩阀体落下,从内桶底部的孔排水,脱水时,要先将内桶解锁再进 ...
