Embodiment 1

[0037] Such as figure 2 As shown, on the basis of the above-mentioned embodiments, the maintenance method for a water purification device of a water purification washing machine according to Embodiment 1 of the present invention further includes: obtaining the membrane flow rate of the membrane module when the water purification device is purifying water. When the membrane flux of the membrane module is lower than the preset value, the water purification device receives the cleaning command and suspends the water purification; step S106, connects the water inlet of the washing machine with the membrane module, controls the cleaning water to flow into the membrane module, and executes the first Clean the membrane components.

[0038] The maintenance method of the water purifying washing machine water purifying device of the present embodiment is:

[0039] First, step 104 is executed to obtain the membrane flux of the membrane module when the water purification device purifies...

Embodiment 2

[0050] Such as Figure 1-3 As shown, as a further preferred mode of the embodiment of the present invention, on the basis of the above-mentioned implementation mode, the first time t A greater than or equal to the second time t B , preferably, t A and t B The relationship is: t A = 2t B , this is because in the first stage of water purification process before time point A, the membrane module filtered more dirt in the laundry water, and as the filtration progressed, the dirt in the laundry water was gradually filtered out and decreased, so the dirt The accumulation on the membrane module is mainly concentrated in the first water purification process before time point A, so t A The setting time is longer, which can fully wash the dirt on the membrane module and maintain the performance of the membrane module more effectively. On the other hand, t B The setting time is short, which can effectively avoid the waste of water resources, and use less water while achieving the ...

Embodiment 3

[0053] Such as Figure 4 As shown, on the basis of the above-mentioned embodiments, the embodiment of the present invention provides a washing machine adopting the above-mentioned maintenance method for the water purification device of the washing machine, including: a washing tub, a circulating water pipeline, a drainage pipeline, and a membrane module, the membrane module It has a water inlet, a water production port and a sewage discharge port. The membrane module is connected to the circulating water pipeline through the water inlet and the water production port, and the membrane module is connected to the drainage pipeline through the sewage discharge port (not shown in the figure). Inlet water cleans the flushing port of the membrane module, and the flushing port communicates with the water inlet of the washing drum. Since the membrane module is cleaned with a specially set flushing port, the flushing port and the water production port do not share the same port.

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, the water producing outlet and a sewage discharge outlet, the membrane assembly is connected to the circulating water pipeline through the water inlet and a 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 that the water purifying device receives a water purifying command; washing water is controlled to be input into a membrane component; after the water purifying device runs for one cycle, water purifying is stopped, and the washing water is controlled to be input into the membrane component. According to the water purifying washing machine and the washing machine adopting the maintenance method, 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...
