Description

A flocculation filter and a flocculation washing machine

technical field

The invention relates to a washing machine which performs flocculation treatment on washing water for recycling, and particularly relates to a flocculation filter for filtering the washing water after the flocculation treatment.

Background technique

With the improvement of people's living standards, washing machines have now become one of the main household appliances in people's daily life. The laundry process of the washing machine mainly includes several stages of washing, rinsing, and drying. During the washing stage, the washing machine enters water and detergent to wash the clothes. , after entering the rinsing stage, in order to rinse the stains and residual detergent, it is necessary to enter more water or perform more rinsing times to rinse the clothes, which will inevitably consume a lot of water resources, even for a water-saving front-loading washing machine, in order to Rinse clothes also need to be rinsed at least twice, and this process consumes at least 30L of tap water. Sometimes there are fewer stains on the clothes or less detergent is put in, and it may be rinsed twice. However, because the user chooses 3 rinses, it will inevitably lead to waste of water resources. For example, a 6Kg fully automatic washing machine usually takes two rinses. The basic water consumption of rinsing water is about 100 liters. How to save water and electricity while washing clothes has always been one of the focuses of consumers.

So far, there is no water purification and recycling device for household washing machines. Even the so-called washing machines with water-saving functions generally install a water storage tank on the side of the washing machine, and use a water pump for water injection and drainage. Rinse 3 times to save water. However, the water after washing cannot be preserved, and at the same time, the structure of the washing machine itself is complicated and bulky, which is not conducive to transportation, recycling, and the like. Due to the limitations of volume, structure and flexibility, the original function of the washing machine and the function of the water-saving tank itself are affected. And the water saving efficiency of this technology is low.

At the same time, based on the existing laundry methods, in order to better save water resources, washing and/or rinsing water is purified by technical means, and recycled during the washing process to achieve the purpose of water saving. The washing water is treated by flocculation, and the treated water is used for rinsing. The flocculant reacts with the stains and detergents in the washing water to form flocs, which settle or float, so that the water and pollutants are separated to achieve the purpose of purification.

However, in the process of flocculating the washing water, the washing water after the flocculation treatment needs to be filtered. Since each washing process of the washing machine requires at least one flocculation treatment, the filter element of the filter device needs to be disassembled frequently. to clean or replace the filter element. For the filter in the prior art, the disassembly of the filter element is complicated, and the cleaning process of the filter element is complicated.
