Description

A washing machine inner cover with a spray structure and a washing machine with the inner cover

technical field

The invention relates to the field of washing machines, in particular to an inner cover of a washing machine, in particular to an inner cover of a washing machine with a spray structure.

Background technique

At present, there are endless development types of washing machines all over the world. In response to the needs of people's lives in the market, designers have developed washing machines with various functions from different angles, such as: washing machines with spray devices.

But, there is following shortcoming in the spray washing machine of the prior art:

1) When the centrifugal method is used to form a waterfall spray, there are certain requirements for the water level and the speed of the inner bucket, and if the water level is too low or the speed of the inner bucket is not enough, the effect of the waterfall spray cannot be achieved;

2) The spray water sprayed by the spray device is in an uncertain position in the front and rear of the barrel, and the water flow is unstable from time to time.

Application number is that the Chinese patent of 200410004726.9 discloses a kind of inner circulation spraying washing machine, adopts the washing method of circulating spraying, and a spraying device is set on the washing machine outer bucket cover, reaches the effect of spraying and washing. The spraying device includes: a water injection pipe, a water cavity, a waterfall forming part, and a limit baffle, and the water cavity is composed of an upper water cavity and a lower water cavity. The washing water is pressed into the spray device through the circulation pipe by the water pump, and first enters the water cavity, where the water is temporarily stored. The wash water then reaches the place where the waterfall is formed, where it is "compressed" to form the rudiment of the waterfall. Finally, the waterfall is limited by the limit baffle and sprayed in the inner bucket.

The Chinese patent with the application number of 200710129867.7 is an outer barrel cover with a spray function and a washing machine using the outer barrel cover. It discloses an outer barrel cover with a spray function and a washing machine using the outer barrel cover. The washing machine includes : It is equipped with a washing inner tub for holding laundry, a washing outer tub for placing washing inner tub to accommodate washing water, a driving device and a drainage device are provided at the bottom of the washing outer tub, and a circulation pipe is provided at the output end of the drainage device. The barrel wall reaches the water flow input port of the spray device arranged on the outer barrel cover, and the spray device is arranged on the side wall of the outer barrel cover, including an inclined water injection port and a waterfall forming part connected with the water injection port, the circulation pipe and the injection port The mouth of the water is connected.

Although the above-mentioned spraying device can achieve the effect of spraying and rinsing, the process is complicated, the structure is relatively complicated, and the cost is high.

The dehydration side of the existing double-tub washing machine sprays and rinses the water into the dehydration bucket through the water distribution tank or the joint. When the water flow is concentrated into the dehydration bucket, it becomes a waterfall. Larger, resulting in uneven spray rinsing, low utilization rate of spray water and waste of water.

In view of this, the present invention is proposed.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an inner cover of a washing machine that directly connects with the spray port of the existing washing machine when the inner cover is closed.
