Laundry treating apparatus and method for controlling feed water valve

Abstract

The invention relates to a laundry treating apparatus and method for controlling a feed water valve. The laundry treating apparatus may include: a plurality of cleaning nozzles provided at a circulation path which is used for circulating air in a tub and configured to inject water; a plurality of water supply passages having one side connected to a water supply source and having another side connected to the plurality of cleaning nozzles; a plurality of water supply valves configured to open and close the water supply passages; and a controller for sequentially controlling the water supply valves such that at least one of the water supply valves is open and another water supply valve is closed, such that at least one of the plurality of cleaning nozzles is open to allow water to be continuously supplied from the water supply source. Therefore, the laundry treating apparatus is capable of preventing occurrence of a water hammer due to water supply for cleaning and preventing damage and noise of a component resulting from water hammer.

Description

technical field [0001] The invention relates to a laundry treatment device and a water supply valve control method thereof. Background technique [0002] As is well known, a laundry treating device is a type of device that processes (washes) clothes or laundry through a washing process and a rinsing process. [0003] The laundry refers not only to clothing, but also to items that can be washed, such as bedding such as futons, curtains, and dolls. [0004] The laundry treating apparatus has a dehydration function for rotating washed clothes or laundry at a preset speed to remove moisture. [0005] Some of the laundry processing apparatuses have not only a washing function but also a drying function for supplying heated air to washed clothes or laundry for drying. [0006] A part of the laundry processing device having the washing function and the drying function includes: a water tank; and a circulation flow path for drawing air in the water tank to the outside of the water...

AI Technical Summary

Problems solved by technology

[0015] However, in such a conventional laundry treating device, the water supply valve is opened and closed a preset number of times so that water can be selectively supplied to each nozzle, and there is a problem that, when the water supply valve is closed, The pressure changes, so the water supply flow path is impacted, resulting in a water hammer effect called WATER HAMMERING

[0016] In the case where water hammer is generated by selectively opening and closing the water supply valve, there is a problem that the forced deterioration of the water supply channel is promoted and the life is shortened.
