Pump of washing device

Abstract

The invention discloses a pump of a washing device. The pump comprises a pump body, wherein a pump cavity used for containing a liquid is arranged in the pump body; the pump body is provided with a liquid inlet and a liquid outlet, wherein the liquid inlet and the liquid outlet communicate with the pump cavity; and an impeller connected with a motor is arranged in the pump cavity. The pump also comprises a heating component and a pressure induction part, wherein the heating component extends from the outer part of the pump body into the pump cavity and heats the liquid in the pump cavity; thepressure induction part is arranged on the pump body for inducing a liquid level in the pump cavity; the impeller divides the pump cavity into a first cavity which is near the liquid inlet, and a second cavity which is far away from the liquid inlet; and the heating component is arranged in the second cavity. By use of the pump of the washing device, the volume of the pump body is reduced, a washing and containing space of the washing device is enlarged, meanwhile, a situation of a drainage area in the pump cavity is improved through the improvement of the structure of the impeller, so that aflow rate is even, an impact on a cavity wall is reduced, in addition, a thermal field in the pump cavity becomes even through the structure change of the heating component, and a problem brought by thermal force coupling is avoided.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a pump of a washing device. Background technique [0002] With the improvement of living standards, consumers have higher and higher requirements for quality of life, and thus higher and higher requirements for product quality, performance, user-friendly use, and intelligent operation. As an excellent product, dishwashers have gradually entered people's lives. At present, dishwasher technology generally uses a heat pump with integrated washing and heating functions. The pump body with heating function usually includes the upper and lower pump casings, installation The impeller in the pump casing, the motor used to drive the impeller to rotate, and the heating body used to heat the fluid, etc. Several existing heat pumps require a compact liquid-driven and heating component in the application scenario of a type of household appliance that is applied to li...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned prior art has proposed a technical solution for preventing dry heating of the heat pump and the large volume and efficiency of the pump body, it still exists. When the liquid circulates in the pump body, the efficiency is low and the flow uniformity is poor; The installation in the body takes up too much space; there are technical defects in the installation of the heating tube of the heating component, which leads to uneven heating or excessive local stress due to thermal coupling, which affects the life of the heating tube, etc.
