Abstract

The invention discloses a clothes washing water recycling device, a water-saving clothes washing control method and a washing method of the clothes washing water recycling device. The clothes washing water recycling device comprises a washing cylinder, a circulation water pipeline, a drainage pipeline and an ultrafiltration membrane assembly. The water inlet end of the circulation water pipeline is communicated with a water outlet of the washing cylinder, and the water outlet end of the circulation water pipeline is communicated with a water inlet of the washing cylinder. The ultrafiltration membrane assembly is provided with a water inlet end, a first water outlet end and a second water outlet end. The ultrafiltration membrane assembly is connected to the circulation water pipeline through the water inlet end and the first water outlet end, and a gas conveying device is connected to the water inlet of the ultrafiltration membrane assembly. The circulation water pipeline is further provided with a liquid conveying device, and the drainage pipeline is communicated with the second water outlet end of the ultrafiltration membrane assembly. When much dirt is retained on an ultrafiltration membrane, gas washing is performed on the ultrafiltration membrane, and then water is used for washing. Compared with the manner that only water washing is used, washing water can be saved, and cleaning is better and more thorough.

Description

technical field [0001] The invention relates to a washing machine, in particular to a laundry water recycling device, a cleaning method thereof, and a water-saving laundry control method. Background technique [0002] The washing device of the existing washing machine cannot recycle the water in the washing process, and multiple times of rinsing are required after washing. Regardless of whether the clothes are clean or not in each process, a large amount of clean water needs to be replaced, resulting in a large waste of clean water. When the rinsing water is purified and recycled by using ultrafiltration membrane modules, a large amount of clean water can be saved without affecting the washing effect, which is of great significance to the reduction of wastewater discharge. In the prior art, the ultrafiltration membrane module is mostly washed with water, which has the disadvantages of using a large amount of water and not being able to clean it.
