Laundry treatment device and method for controlling water supply valve thereof

Abstract

The invention relates to a laundry processing device and a method for controlling a water supply valve thereof. The laundry processing device has: a plurality of cleaning nozzles arranged in a circulation flow path for circulating air in a water tank for spraying water; a water supply flow path, one side is connected to a water supply source, and the other side is connected to the plurality of cleaning nozzles respectively; a plurality of water supply valves respectively open and close the plurality of the water supply flow paths; In a state where at least one of the plurality of water supply valves is opened, the other is closed, and the plurality of water supply valves are sequentially controlled so that at least one of the plurality of cleaning nozzles is opened, and the water supply source is opened. water can flow out continuously. Thereby, it is possible to suppress the water hammer action that occurs when water is supplied for cleaning, and it is possible to suppress damage to components and noise due to the water hammer action.

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.
