Description

Water-saving spray washing system for double-tub washing machine

technical field

The utility model relates to a water circulation system of a double-tub washing machine.

Background technique

Double-tub washing machines have a very wide range of users. Its structure and function are relatively simple. The following problems exist in actual use:

1. When the water volume in the washing tub is not high enough, or some lighter clothes are difficult to immerse in water, the washing effect is affected;

2. In the washing process, only rely on a net bag arranged on the side wall to collect the fluff in the washing water, but the collection effect is not ideal, and a large amount of fluff often adheres to the clothes.

3. Due to the limited washing capacity of the washing machine, users often need to wash two or even three buckets of clothes at a time. The water from the dehydration bucket of the double-tub washing machine is directly discharged through the dehydration outer bucket through the three-way valve and the drain pipe, which makes the large amount of detergent-containing water that comes out of the clothes unable to be recycled and reused. When the previous bucket of clothes is dehydrated after washing, the clothes take away a lot of water, so that a lot of water must be added when washing the last bucket of clothes, and a certain amount of detergent must be put in again, which causes a lot of waste. The waste of water and detergent also increases environmental pollution.

Detailed ways

In this embodiment, the water-saving spray washing method of the double-tub washing machine includes:

During the washing process, the water in the washing bucket is circulated in the washing bucket to be washed by spraying; in order to enhance the filtration of fluff, the water in the washing bucket is filtered and circulated in the washing bucket to spray Washing in this way has a significant effect in improving the washing effect.

The water taken out of the dehydration tub from the previously washed clothes is returned to the washing tub to be used as the washing water for washing the clothes in the next washing tub. In a specific implementation, the return of the water extracted from the dehydration bucket includes the return of washing water and the return of rinsing water.

Referring to Fig. 1, Fig. 2 and Fig. 3, the water-saving spray washing system of the double-tub washing machine in this embodiment is provided with a multifunctional valve body 8 including a circulation valve E and a drain valve F, and the water path communicated by the multifunctional valve body 8 Including:

The outlet water of the washing tub interface B is connected to the water pump 6 through the circulation valve E in the multi-function valve body 8, the water outlet D of the circulation valve, the inner connecting pipe 7, and the inner connecting pipe interface G in turn, and the water outlet H of the water pump 6 passes through the spray hose 3 It communicates with the spray head 4, and the spray head 4 is arranged in the washing bucket 5 to form a spray washing system;

The outlet water from the interface B of the washing tub is connected to the drain pipe 11 through the circulation valve E and the drain valve F in turn, forming a straight drainage system of the washing tub;

After the outlet water of the dehydration bucket 2 passes through the inner cavity of the functional body valve body 8, the inner connecting pipe 7, the inner connecting pipe interface G, the water pump 6, and the spray hose 3, it communicates with the spray head 4 arranged in the washing bucket 5 to form a Dehydration reuse system;
