Liquid detergent feeding device

Abstract

The invention discloses a liquid detergent feeding device, which consists of an electromagnetic water supply valve (1), a liquid detergent tank (2), a flushing valve (3), an attraction generator (4), a water box (5), a flow sensor (6) and related pipelines. A valve cavity (3014) is formed in the valve body of the flushing valve, the exterior of the valve body is provided with a water outlet nozzle (302) communicated with the valve cavity, the valve cavity is provided with a liquid inlet valve seat (30141), the valve body is provided with a guide pipe (311), an electromagnetic coil (305) is sleeved outside the guide pipe, and the inner rear part of the guide pipe is provided with a fixed iron core (306) and a movable iron core (307); the attraction generator (4) is provided with a water inlet nozzle (401), a water outlet nozzle (402) and an attraction port (404); a shrinkage port (403) is in communicated connection between the water inlet nozzle (401) and the water outlet nozzle (402); and a water outlet A (102) of the electromagnetic water supply valve is connected with a water inlet nozzle (310) of the flushing valve, and a water outlet B (103) of the electromagnetic water supply valve is connected with the water inlet nozzle (401) of the attraction generator. The device is suitable to be used as a washing equipment detergent feeding device.

Description

technical field [0001] The invention relates to a liquid distributing device, in particular to a detergent dispensing device fitted on electric washing machines such as electric washing machines and electric dishwashers. Background technique [0002] In the past, the method of adding liquid detergent (such as detergent, softener, softener, sterilizing solution, etc.) to electric washing machines such as electric washing machines and electric dishwashers using liquid detergent was that the liquid detergent that the user would put in was added in advance. Stored in the designated container, the washing equipment flushes them into the washing drum through water flushing or other mechanical methods according to the washing process. The dosage of this method depends on the operation of the user, and at the same time, detergent needs to be added to the container during each washing process. With the continuous liquefaction of detergent, a large amount of detergent is stored insid...

AI Technical Summary

Problems solved by technology

[0010] The present invention aims to solve the problems of inaccurate metering of liquid detergent in existing electrical washing equipment, and the problem that the metering device is prone to blockage or jamming and is not convenient for metering and metering. Therefore, a liquid detergent metering device of the present invention is provided. The device is equipped with a suction generator and a flushing valve. The suction generator generates a negative pressure when the washing equipment is fed into the water. Under the combined action of the flushing valve, the liquid detergent is attracted and mixed into the incoming water flow. The dosage is measured by the flow sensor and fed back to the controller. When the specified dosage is reached, the liquid inlet valve of the flushing valve is closed, and then the valve and the entire suction pipeline are flushed with tap water to prevent the detergent components inside the pipeline from becoming clogged after being concentrated;
