Description
Technical Field
The invention belongs to the technical field of washing machines, and particularly relates to a washing machine drainage control method and a washing machine.
Background
In order to save water resources, the current washing machine is provided with a water recycling structure to reuse washing and rinsing water in a washing process, and in order to enable the washing and rinsing water to meet the reuse condition, a water purifying device is required to be arranged to remove impurities and the like in the water so as to improve the cleanliness of the water.
In the process of using the circulating water of the washing machine, lint in the water needs to be filtered and then the water needs to be further purified.
In the washing and rinsing water recycling, lint and the like in the water also need to be removed to prevent the lint from remaining in the laundry. Most of thread scraps collectors of the existing washing machine are arranged at the front end of a drainage pump or a drainage valve, the main function of the existing washing machine is to intercept large foreign matters such as hairs and hairpins, clip, coins and the like in water, and the main purpose of the existing washing machine is to prevent the large foreign matters from blocking the drainage valve or the drainage pump and being difficult to achieve the effect of intercepting thread scraps in water. The discharge of the thread scraps in the water is mainly discharged together with the waste water discharged from the washing machine. In each drainage process of the washing machine, most of thread scraps are adhered to the clothes and cannot be removed due to the interception effect of the clothes. The main solution is to increase the rinsing times and the rinsing water amount, thereby achieving the purpose of reducing the thread scraps, and thus, the waste of time and water resources is inevitably caused.
The existing thread scrap filtering device adopts a chemical fiber screen, the interception effect is better, but the thread scrap filtering device needs to be taken out for manual cleaning, the self-cleaning of the filtering device cannot be realized, and the use is inconvenient.
