Description

A circulating water-saving drum washing machine

technical field

The utility model relates to a washing machine, in particular to a circulating water-saving drum washing machine. the

Background technique

Washing machine is one of indispensable household appliances in people's life, along with the development of technology and people's higher and higher requirement to laundry, drum washing machine more and more occupies important position. The drum washing machine is driven by the motor to rotate the inner drum, and the clothes in the drum are brought to a certain height by the lifting ribs to generate a beating force, which effectively removes the stains attached to the clothes and achieves the purpose of washing. In order to improve the cleanliness of the clothes, it is necessary to add washing powder to remove the dirt on the clothes when washing the clothes. the

At present, when washing clothes, the drum washing machine first dissolves the detergent in water, and then fully soaks the clothes in it through a large amount of water, so as to finally achieve the purpose of washing and rinsing the clothes, and its water consumption is relatively large; The activity of active enzymes in washing powder promotes the ability of washing powder to wash dirt. Most drum washing machines have the function of heating water, which also increases power consumption. the

Utility model content

The utility model aims to solve the above-mentioned shortcomings, and provides a circulating water-saving drum washing machine, which realizes the recycling of washing water and achieves the purpose of water saving. the

In order to achieve the above effects, the utility model provides a circulating water-saving drum washing machine, which includes an outer tub and an inner tub. A water storage tank is provided at the drain outlet at the bottom of the outer tub. The water end is connected, and the water outlet end of the two-way pump is respectively connected with a drainage pipe and a circulating water pipe, and the water outlet end of the circulating water pipe is located at the top of the inner barrel. the

Further, in order to achieve the purpose of fully wetting the clothes, the water outlet end of the circulating water pipe is connected to the water inlet end of the solenoid valve, and the two water outlet ends of the solenoid valve are fixedly connected with a first nozzle and a second nozzle respectively; the solenoid valve It is electrically connected with the controller of the washing machine. the

Further, the water outlet end of the water storage tank is provided with a filtering device. The water storage tank can effectively collect the water in the inner barrel, and its built-in detachable filter device can effectively filter the sundries in the water to prevent the one-way valve, two-way pump, nozzle and other devices behind from being blocked; The device is flexibly connected with the water storage tank, is detachable, simple and convenient, easy to clean, and is not conducive to the growth of bacteria. the

Furthermore, a one-way valve is provided on the connecting water pipe between the filtering device and the two-way pump. the

The one-way valve in the utility model is to prevent the sewage in the water pipe from flowing back into the inner bucket due to incomplete drainage after the drainage is completed, thereby causing secondary pollution of the inner bucket. the

The solenoid valve located on the top of the inner bucket can effectively control the opening and closing of the two nozzles, which fully improves the efficiency of spraying the clothes. the

The utility model is equipped with a two-way pump at the bottom of the outer barrel of the drum washing machine. The water in the inner barrel is collected in the water storage tank and then filtered by the filter device, and then passes through a one-way valve to reach the water inlet of the two-way pump. The rotation direction of the two-way pump is fixed, and the passage of the conduction and the circulating water pipe makes the water reach the solenoid valve located on the upper part of the inner bucket from the circulating water pipe, and then the solenoid valve controls the opening of the two nozzles, and then sprays on the surface of the clothes, so that only a small amount is needed The water can fully moisten the clothes to achieve the purpose of water saving. the

Due to the different rotation directions of the inner tub, the concentration positions of the clothes are different. The utility model opens the left and right nozzles located on the top of the inner barrel according to the rotation direction of the inner barrel through the electromagnetic valve electrically connected with the controller of the washing machine. That is, when the inner tub rotates clockwise, the clothes are piled up on the left side of the inner tub, the controller of the washing machine controls the electromagnetic valve to open the water outlet hole connected to the first nozzle, and the other water outlet hole is closed, and the circulating water is sprayed out over a large area through the first nozzle Soak the clothes; when the inner bucket rotates counterclockwise, the solenoid valve communicates with the second nozzle, and the circulating water is sprayed out through the second nozzle to soak the clothes in a large area. In this way, the water in the bucket can be recycled to repeatedly moisten the clothes, so as to save water and ensure the spraying efficiency of the circulating water at the same time. the

When the washing machine finishes washing and discharges water, the two-way pump rotates in the opposite direction, so that the water in the inner barrel flows to the drain through the two-way pump, so that the washing or rinsing sewage in the inner barrel is directly discharged through the drain. the

So the utility model has the following beneficial effects:

1. Since there is a two-way pump at the bottom of the outer tub of the drum washing machine, the forward and reverse rotation of the two-way pump can realize the recycling or discharge of water.

2. When the water in the inner bucket of the washing machine reaches a certain water level, it enters the circulating water pipe through the two-way pump, and then sprays it on the top of the clothes through the nozzle, so as to fully wet and moisten the clothes, save water and clean the clothes at the same time Purpose. the

3. There is a one-way valve on the water pipe at the drain of the washing machine to prevent the sewage in the water pipe from flowing back into the inner tub due to incomplete drainage after the drainage is completed, thereby causing secondary pollution of the inner tub. the

4. The outlet end of the water storage tank is equipped with a filter device, which can effectively remove particles or flocs in the circulating water, and prevent blockage of the one-way valve, two-way pump and nozzle behind. In addition, the filter device and the water storage tank are movably connected, detachable, simple, convenient, easy to clean, and are not conducive to the growth of bacteria. the

5. According to the rotation direction of the inner bucket, the two nozzles are controlled by the solenoid valve to spray water alternately, so that the water can soak the clothes as much as possible, and the spraying efficiency of circulating water is improved. the
