Detergent dispensing device and washing machine

Abstract

The invention discloses a detergent dispensing device, which comprises a water box and a liquid storage box. The inner wall of the water box is provided with a boss protruding toward the inside of the water box and extending along the axial direction of the water box. The boss of the boss is The upper surface is a support surface, and the liquid storage box is placed on the support surface of the boss, and is pulled and moved along the extension direction of the support surface. The boss is provided with at least one gap through the support surface, so that the support surface Water flows into the water box from the gap. The invention provides a gap on the support surface, and leads the water flow on the support surface to the inside of the water box without affecting the pulling movement of the liquid storage box, effectively solving the problems of overflow and leakage of the water box, and improving user experience.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a detergent dispensing device, in particular to a washing machine. Background technique [0002] Most washing machines are equipped with a detergent injection device, which includes a water box and a liquid storage box that slides along the inner guide rail of the water box. In the chamber corresponding to the liquid box, the water will splash around, and a part of the water will splash on the guide rail between the liquid storage box and the water box. To the main control board, too much water will flow to the floor, causing water leakage and threatening the safety of users. [0003] In addition, the water inlet of the detergent dispensing device is connected to the water inlet valve. After the water inlet valve fails, the water flow cannot be controlled, which may cause the water flow to exceed the actual load flow of the liquid storage box, and the water in the...

Problems solved by technology

[0002] Most washing machines are equipped with a detergent injection device, which includes a water box and a liquid storage box that slides along the inner guide rail of the water box. In the chamber corresponding to the liquid box, the water will splash around, and a part of the water will splash on the guide rail between the liquid storage box and the water box. To the main control board, too much water will flow to the floor, causing water leakage and posing a threat to the safety of users

[0003] In addition, the water inlet of the detergent dispensing device is connected to the water inlet valve. After the water inlet valve fails, the water flow cannot be controlled, which may cause the water flow to exceed the actual load flow of the liquid storage box, and the water in the liquid storage box Will overflow, cause leaking faults, damage the washing machine

[0004] In response to the above problems, a flow solenoid valve is installed in the washing machine to control the water flow and reduce the impact of water, thereby solving problems such as water leakage and overflow. However, the impact of water is small, and it is impossible to wash and wash clothes. It cannot fundamentally solve the problem. Once the flow solenoid valve fails, the water leakage problem is inevitable
