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 washing machine includes: a detergent tank (117), which is installed in the tank storage box (114); and a liquid agent automatic feeding device, which supplies the liquid agent of the detergent tank (117) to the sink. The detergent tank (117) has a cylinder portion (123) that discharges the liquid agent. The liquid agent automatic injection device includes a detergent-side cylinder connected to the cylinder (123). The tank storage box (114) has an inclined surface (114j) formed on the side wall and inclined downward toward the cylinder part (123) and the detergent side cylinder part, and a hole (114k). 114k) is formed above the inclined surface (114j), and injects water toward the inclined surface (114j). Thereby, the liquid agent etc. adhering to the connection part of the detergent tank (117) and the automatic liquid agent injection device can be washed away with water every time water is supplied.

Description

technical field [0001] The present invention relates to a washing machine equipped with an automatic liquid injection device constituting a liquid supply device. Background technique [0002] In the past, this type of drum-type washing machine includes a detergent container, a liquid tank, and an automatic liquid injection device. It is fixed to the rear 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 front surface of the main body of the washing machine. 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 has a storage room for storing the liquid tank. The liquid tank stores liquid detergent or liquid softener. The liquid tank has a liquid agent supply port formed on the rear wall surface for ...
