Maintenance method of water purifying device of water purifying washing machine and washing machine adopting maintenance method

Abstract

The invention provides a maintenance method of a water purifying device of a water purifying washing machine and a washing machine adopting the maintenance method. The washing machine comprises a washing drum, a circulating water pipeline, a drainage pipeline and a membrane assembly. The membrane assembly is provided with a water inlet, a water producing outlet and a sewage discharge outlet, the membrane assembly is connected to the circulating water pipeline through the water inlet and the water producing outlet, the membrane assembly is connected to the water discharge pipeline through the sewage discharge pipeline, the membrane assembly is further provided with a washing inlet used for inputting intake to washing the membrane assembly, and the washing outlet is communicated to the water inlet of the washing machine. The maintenance method of the water purifying device comprises the steps of running the water purifying device for one cycle, executing membrane assembly washing twice, wherein the time length of executing first membrane assembly washing is related to the time in the water purifying running cycle of first membrane assembly washing. According to the water purifying device of the water purifying washing machine and the washing machine thereof, the washing problem of a filter membrane component in the existing water purifying washing machine is solved, meanwhile, the washing method of the filter membrane component is simplified, the water consumption of washing the filter membrane component is saved, and the production of the water purifying washing machine is reduced.

Description

technical field

[0001] The invention relates to a washing machine, in particular to a maintenance method for a water purification device of a water purifying washing machine and the washing machine. Background technique

[0002] The working process of the existing washing machine usually includes water intake, washing-spin-drying-drainage, multiple rinsing-spin-drying-drainage, etc. During the working process, the laundry wastewater is generally discharged directly out of the washing machine, and a large amount of water is re-injected. Clean water rinses the clothes multiple times, resulting in a large water consumption throughout the laundry process.

[0003] In order to achieve the purpose of saving water in the washing machine, the prior art proposes to use filter membrane modules to purify and recycle the used laundry water, for example, to filter and recycle the laundry water discharged after the rinsing process. However, the filter membrane module used to circulate an...

Examples

Embodiment 1

[0036] On the basis of the above-mentioned embodiments, the maintenance method of a water purification device of a water purification washing machine according to Embodiment 1 of the present invention, wherein a cycle of operation of the water purification device includes at least three time periods, and the first cleaning of the membrane module is performed When the time point of the water purification device is running in different time periods, the time for cleaning the membrane components for the first time is different.

[0037]For washing water with different levels of dirt, in order to facilitate the determination of the different durations for performing the first cleaning of the membrane module, the method provided by Embodiment 1 of the present invention is to divide the operation cycle of the water purification device into several time stages, in different The first cleaning of the membrane components is carried out in the time period of , indicating that the degree ...

Embodiment 2

[0041] On the basis of the above embodiments, the second embodiment of the present invention provides a maintenance method for a water purification device of a washing machine, wherein the durations t1, t2 and t3 for cleaning the membrane module are sequentially decreased. After a lot of experiments, the inventor preferred that the operation cycle of the water purification device be the first time period, the second time period and the third time period in sequence. When the membrane module is cleaned for the first time in the first time period, it means that the degree of dirtiness of the washing water is the highest, and the time t1 required for cleaning the mold module is the longest; when the membrane module is cleaned for the first time in the third time period, it means that the laundry water The degree of contamination of the water is the lowest, and the time t3 needed to clean the module is the shortest; therefore, the time t1, t2 and t3 for cleaning the membrane module...

Embodiment 3

[0044] On the basis of the above-mentioned embodiments, the maintenance method for a water purification device of a washing machine according to Embodiment 3 of the present invention, wherein the membrane flux of the membrane module is automatically detected and obtained during the water purification of the water purification device, and pre-set Set a membrane flux value. As the water is purified, the dirt intercepted by the membrane module increases, and the membrane flux gradually decreases. When it is automatically detected that the membrane flux of the membrane module decreases to the preset membrane flux value, Perform the first cleaning of the membrane module, which can effectively maintain the performance of the membrane module.

[0045] Further, automatically detect and obtain the membrane flux of the membrane module and preset a membrane flux value when the water purification device purifies water, or it can be replaced by automatically detecting and obtaining the wate...
