Description

一种外桶盖及洗衣机External lid and washing machine

技术领域Technical field

本发明属于洗衣机技术领域，具体涉及一种外桶盖及洗衣机。The invention belongs to the technical field of washing machines, and in particular relates to an outer tub cover and a washing machine.

背景技术Background technique

目前，具有喷淋功能的洗衣机一般都设置有循环水泵，通过循环水泵将外桶底部的水抽取至外桶盖，由外桶盖出水、形成喷淋状的水流。其中，外桶盖一般包括进水口、水腔和出水口，水流通过进水口进入外桶盖的水腔，聚集在水腔中的水从出水口出水、进行喷淋。At present, the washing machine with the spray function is generally provided with a circulating water pump, and the water at the bottom of the outer tub is extracted to the outer tub cover by the circulating water pump, and the water is formed by the outer tub to form a spray-like water flow. The outer lid generally includes a water inlet, a water chamber and a water outlet, and the water flows through the water inlet into the water chamber of the outer lid, and the water collected in the water chamber is discharged from the water outlet and sprayed.

但是，由于水腔是一个环形腔体，水从进水口进入时，大部分的水流只经过进水口附近的水腔后便从对应的出水口位置流出，不能使水流均匀地从出水口所有位置流出，喷淋覆盖面积小，即不能达到全面有效的喷淋效果。尤其，在进水水压不足或者水流缓慢的情况下，只有与进水口位置对应的出水口位置才会正常出水，喷淋效果很差，衣物洗净效果难以得到实质的改善。However, since the water chamber is an annular chamber, when water enters from the water inlet, most of the water flows only through the water chamber near the water inlet and then flows out from the corresponding water outlet, so that the water flow cannot be uniformly distributed from all positions of the water outlet. Outflow, the spray coverage area is small, that is, the full and effective spray effect cannot be achieved. In particular, in the case of insufficient water pressure or slow water flow, only the position of the water outlet corresponding to the position of the water inlet will be normal, and the spray effect is poor, and the washing effect of the clothes is difficult to be substantially improved.

有鉴于此，特提出本发明申请。In view of this, the present invention is filed.
