Problems solved by technology

[0007] However, in the structure of the conventional drum-type washing machine, the liquid agent may adhere to the connecting portion of the liquid tank and the liquid agent automatic injection device, causing the connecting portion to stick.
When the liquid agent is stuck to the connection part, if the liquid tank is pulled out from the liquid agent automatic injection device, there is a danger that the adhesive will enter the detergent supply water channel from the suction port of the cylinder body and cause pressure loss in the water channel.
In addition, when the adhesive adheres to the sealing member of the liquid tank and the automatic liquid injection device, it will affect the liquid tightness of the joint.
Therefore, the liquid agent automatic feeding device cannot stably discharge the required amount of detergent liquid or softener liquid
As a result, there is a possibility that washing performance and rinsing performance may decrease.

Abstract

The present invention is provided with: a detergent tank (117) which is attached to a tank housing case (114); and an automatic liquid detergent feeding device which supplies a liquid detergent in thedetergent tank (117) to a water tub. The detergent tank (117) includes a cylindrical part (123) which ejects the liquid detergent. The automatic liquid detergent feeding device is provided with a detergent-side cylindrical part which connects to the cylindrical part (123). The tank housing case (114) has: an inclined surface (114j) which is formed on a side wall and which is inclined downward toward the detergent-side cylindrical part and the cylindrical part (123); and a hole (114k) which is formed above the inclined surface (114j) and into which water is injected toward the inclined surface(114j). This allows the liquid detergent or the like, adhering to a connection part between the detergent tank (117) and the automatic liquid detergent feeding device, to be washed off with water each time water is supplied.

Description

Technical field [0001] The present invention relates to a washing machine equipped with an automatic liquid agent injection device constituting a liquid supply device. Background technique [0002] Conventionally, such a drum-type washing machine includes a detergent container, a liquid tank, and an automatic liquid agent injection device. The detergent container is fixedly coupled to the washing machine body, the liquid tank is detachably connected to the detergent container, and the liquid agent automatic injection device It is fixed to the back of the detergent container (for example, refer to Patent Document 1). [0003] The drum-type washing machine disclosed in Patent Document 1 includes a detergent container provided on the upper part of the front surface of the washing machine body. The detergent container has a suction port formed in the upper part of the rear wall surface and a discharge port formed in the lower part of the rear wall surface. The detergent container is ...
