Structure of a dishwasher water pump

Abstract

The invention relates to a water pump structure of a dish washing machine. The water pump structure is characterized in that a lower cover clings to a motor, a water inlet, a water spray opening and a drain outlet are formed in an upper cover, the water inlet and the water spray opening are formed side by side, and the drain outlet is perpendicular to the water inlet; a flow guide plate is arranged on a side wall of the upper cover and is positioned between the water inlet and the water spray opening, and a non-return plate is arranged at the tail end of the flow guide plate in an extending manner and is opposite to the water inlet; a drain valve is arranged at the drain outlet and can reciprocate in the drain outlet. The water pump structure has the advantages that water spraying, draining and spraying force increasing effects mainly can be realized by means of guiding water flow, and backflow can be reduced; the drain valve is arranged at the drain outlet and mainly can be opened and closed by the aid of impact force of the water flow, and accordingly the water spraying and draining effects can be realized by the simple structure.

Description

technical field [0001] The invention relates to a dishwasher water pump structure. Background technique [0002] The traditional dishwasher water pump generally needs to add complex structures such as baffles. The complex structure has a small injection force, and the water inlet, water spray and drainage need to be controlled by solenoid valves, which greatly increases the cost. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical solution for a dishwasher water pump structure. [0004] The structure of a dishwasher water pump includes a motor and a pump body. The impeller provided at the output end of the motor rotates and fits in the pump body. The pump body is composed of an upper cover, a lower cover and a silicone gasket, and is characterized in that the lower The cover is attached to the motor, and the upper cover is provided with a water inlet, a water spray port and a wa...
