specific Embodiment approach 1

[0037] Embodiment 1. The water inlet flow path 200 is provided with a water inlet valve 220. When the water inlet of the washing machine reaches the set water level, the control system 300 controls the water inlet valve 220 to complete the closing action for a period of time t1 to maintain the pressure value of the public flow path 210 at within a certain pressure range. When the water inlet valve 220 is suddenly closed, a large negative pressure will be generated in the public flow path 210. When the water inlet valve 220 is controlled to complete the closing action after a period of time t1, it can avoid sudden closing and cause excessive pressure fluctuations in the public flow path 210. . The value of t1 lasted is the data obtained through multiple tests before the washing machine leaves the factory and is recorded in the controller of the control system 300. The value of t1 needs to meet the requirement that the water inlet valve 220 completes the closing action without c...

specific Embodiment approach 2

[0038]The automatic dispensing system also includes a voltage stabilizing system 400, which is used to adjust the pressure value of the public flow path 210; The value is within a certain pressure range. The pressure stabilizing system 400 includes a pressure relief valve 410, and the pressure relief valve 410 is arranged on the public flow path 210; when the washing machine is fed with water to a set water level, the control system 300 controls the opening and closing of the pressure relief valve 410 to adjust the pressure of the public flow path 210. The pressure value is within a certain pressure range. The pressure stabilizing system 400 also includes a pressure detection device 420, which is used to detect the pressure value of the public flow path 210; after the pressure relief valve 410 is opened, the control system 300 determines whether to control the pressure relief valve 420 according to the detection result of the pressure detection device 420. Pressure valve 410 ...

Abstract

The invention belongs to the field of washing machines, and in particular discloses an automatic feeding system for washing machines, a washing machine and a control method thereof. The automatic feeding system for washing machines includes a pump liquid system for feeding clothes treating agents; The water flow path includes a common flow path, the liquid outlet end of the pump liquid system is communicated with the common flow path, and the pump liquid system puts the laundry treatment agent into the common flow path; the control system, the control system is in the When the water inlet of the washing machine reaches the set water level, the water inlet flow path is controlled to be disconnected and the pressure value of the common flow path is maintained within a certain pressure range. The automatic feeding system disclosed by the invention can effectively solve the problem of liquid leakage of the liquid feeding pump of the pump liquid system caused by the negative pressure generated in the flow channel when the water inlet valve is closed.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to an automatic feeding system for washing machines, a washing machine and a control method. Background technique [0002] During the continuous development of the washing machine market in recent years, the tide of consumption upgrading driven by the demand for quality life has led the washing machine industry to carry out continuous technological innovation and development for the needs of healthy washing and care. The traditional washing machine manually adds laundry detergent (or softener) into the detergent delivery device every time, and its main disadvantage is that the user cannot accurately input the amount according to the amount of clothes and the degree of turbidity. At present, some washing machines in the washing machine market have automatic delivery technology, but the delivery system is divided into two types, one is a single delivery flow path design, an...
