Abstract
Description
Technical Field
[0001] This utility model relates to the field of home appliance accessories, and in particular to a detergent dispensing device and a washing machine using the same structure. Background Technology
[0002] A washing machine is a household appliance that uses electrical energy to generate mechanical action to dry clothes. As consumers' living standards improve, their demands for washing machines are also increasing.
[0003] In washing machines, a typical unit consists of a casing and a drum. The drum is located inside the casing, and the drum assembly includes an outer drum and an inner drum, with the inner drum forming a washing chamber. A water inlet box is usually located at the top of the casing, containing a detergent dispenser. When washing clothes using this equipment, the user simply adds an appropriate amount of detergent (such as laundry powder, liquid detergent, or fabric softener) to the detergent dispenser, and the washing machine, depending on its operating status, uses fluid to flush the detergent from the dispenser into the washing chamber.
[0004] Currently, in existing washing machines and other garment processing equipment, the water inlet box has low uniformity of water output, which can easily lead to detergent residue such as laundry powder, liquid detergent, or fabric softener remaining on the inner wall of the detergent dispenser after washing, resulting in incomplete rinsing.
