Description

Washing machine water inlet box assembly and washing machine

Technical field

The invention belongs to the technical field of washing machines, and in particular relates to a water inlet box assembly of a washing machine and a washing machine having the water inlet box assembly.

Background technique

The washing machine is a cleaning appliance that people invented to save labor by using electrical energy to produce clothes. With the improvement of living standards, the washing machine has spread over millions of families, which provides convenience for people's lives.

The water inlet box assembly is an important component of the pulsator washing machine. Before the pulsator washing machine is filled with water, a liquid detergent such as a solid detergent or a washing liquid such as washing powder may be added to the detergent box in the water inlet box assembly. When the water enters, the water flows through the water inlet box assembly, flushes the inner cavity of the detergent box, dissolves the detergent quickly, and causes the detergent to flow to the washing machine inner cylinder along with the water flowing through the gap between the water inlet box and the detergent box.

The water inlet box assembly of the existing pulsator washing machine can be roughly divided into two types according to the manner of discharging the detergent. One is a pullable detergent box, and the detergent box will be washed after being pulled out a certain distance. The agent is added; the other is the top opening of the inlet box assembly, and the detergent is added to the inner chamber through the top. During the use of the washing machine, the water inlet box assembly, especially the gap between the detergent box and the water inlet box, may have detergent residue, splashing, and easy to breed bacteria; however, the current detergent box cannot be conveniently cleaned. It is easy to cause secondary pollution.

In addition, the water inlet box assembly currently on the drum washing machine can be used for placing a solid detergent such as washing powder, or a liquid detergent such as a washing liquid. Generally, a washing powder accommodating chamber and a washing liquid accommodating chamber are respectively disposed on the detergent box. It is more conducive to the dissolution and flushing of the detergent. It is also necessary to set a corresponding water path for each accommodating cavity, so that the structure of the detergent box and the waterway is complicated; however, the space of the water inlet box assembly can be set on the pulsator washing machine. Small, there is no space to separate the washing powder and the detergent accommodating cavity, and only the accommodating cavity of the washing powder structure is used, which leads to insufficient dissolution when using the detergent, and some detergent residue is attached to the bottom surface of the accommodating cavity.
