Liquid detergent feeding device and feeding method thereof

Abstract

The invention discloses a liquid detergent feeding device which comprises a detergent storage box, a sponge body, an extrusion part and a detergent inlet pipeline, wherein the detergent storage box isused for storing liquid detergent; the sponge body is fixedly connected with a rotating shaft and can rotate around the axis of the rotating shaft, the lower end of the sponge body is in contact withthe liquid detergent to adsorb the liquid detergent; the extrusion part is used for extruding partial surface of the sponge body to separate out the liquid detergent; the detergent inlet pipeline isobliquely arranged downwards, the upper port of the detergent inlet pipeline is in butt joint with partial surface of the sponge body, and the lower port of the detergent inlet pipeline is communicated with a water inlet pipe. The invention also discloses a liquid detergent feeding method, and according to the method, the sponge body adsorbing the detergent in the detergent storage box is controlled to rotate by specific number of turns, the sponge body is extruded by the extrusion part to separate out the detergent, the separated-out detergent flows into the detergent inlet pipeline located at the extruded part of the sponge body and is gathered into the water inlet pipe under the action of gravity, so as to accurately control the feeding amount by controlling the sponge body rotation number of turns or speed.

Description

technical field [0001] The invention relates to a liquid dispensing device, in particular to a detergent dispensing device and a dispensing method for electric washing machines such as electric washing machines and electric dishwashers. Background technique [0002] When adding liquid additives (such as detergent, softener, softener, sterilizing liquid, etc.) to washing equipment such as electric washing machines and electric dishwashers that use liquid detergent, the user generally stores the liquid agent to be injected in a designated place in advance. Inside the container, the washing equipment flushes it 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. In order to reduce the user's troublesome operation, and even to automatically adjust the dosage of deter...
