Description

Technical Field

[0001] The invention relates to a detergent dispenser for a washing machine, belonging to the field of clothing cleaning, and also relates to a washing machine equipped with the detergent dispenser. Background Art

[0002] A washing machine is a frequently used household appliance. The washing machine is provided with a detergent dispenser, which mainly includes a water box connected to the water inlet pipe of the washing machine and a liquid storage box contained in the water box. The liquid storage box is usually configured to be retractable in the water box, so that the user can pull out the liquid storage box from the water box and add detergent, and / or softener, and / or disinfectant and other additives into the liquid storage cavity in the box.

[0003] Existing detergent dispensers are generally equipped with a suction pump structure, which uses the suction force generated by the suction pump structure to draw the detergent stored in the liquid storage chamber into the water path, mix it with the incoming water in the water path to form a detergent mixture, and then dispense it outward; however, the suction pump is expensive, which will lead to an increase in the cost of the washing machine.

[0004] In order to solve the above-mentioned problem, the applicant has previously proposed a dispensing device that utilizes the negative pressure generated by the incoming water flow to extract the detergent. However, in order to utilize the incoming water flow to form negative pressure in the waterway of the above-mentioned device, it is generally necessary to set a negative pressure structure such as a Venturi tube section on the waterway, which not only complicates the waterway structure; but also because the negative pressure structure requires not only negative pressure extraction but also flushing, otherwise the detergent and the like retained in the waterway will cause the waterway to be blocked. Therefore, it is necessary to add a suction waterway and a flushing waterway to the waterway of the dispensing device, and some control valve bodies must be installed, which also leads to the problem of complicated waterways and increased costs of the dispenser.

[0005] Therefore, providing a low-cost automatic detergent dispensing device has become a technical problem that those skilled in the art urgently need to solve.
