Washing and draining integrated pump

Abstract

The invention relates to a washing and draining integrated pump which comprises a power device, a washing pump, a drain pump, a washing pump water inlet chamber and a drain pump water inlet chamber, wherein the power device comprises a motor shell, a motor and a motor shaft extending out of the motor shell; the washing pump comprises a washing pump shell, a washing pump cavity, a washing impeller and a washing water outlet; the drain pump comprises a drain pump shell, a drain pump cavity, a drain impeller and a drain outlet; the washing pump water inlet chamber is communicated with the washing pump cavity and is provided with a washing water inlet; the drain pump water inlet chamber is communicated with the drain pump cavity and is provided with a drain inlet; the motor shaft passes through the washing impeller and the drain impeller and can drive the washing impeller and the drain impeller to rotate; a crushing blade is arranged on the motor shaft and food residues are firstly crushed during draining. According to the washing and draining integrated pump, the quantity of parts and the occupied space are reduced; the cost is reduced; integration is improved; and through the functions of crushing and discharging crushed residues during draining, the problem that a user needs to clean a filter net is solved and the user experience is improved.

Description

Technical field [0001] The invention relates to the technical field of dishwashers, vegetable washing machines and the like, and more specifically to a washing and drainage integrated pump. Background technique [0002] Two centrifugal water pumps are usually used on machines such as current general-purpose dishwashers or vegetable washing machines. One centrifugal water pump is used to circulate the water flow in the machine during washing. The water flow is pressurized and sent to the sprayer in the machine, and then sprayed. The centrifugal water pump sucks in filtered water. The other centrifugal water pump is used to discharge unfiltered or simply filtered sewage and residues out of the machine, leaving larger residues behind. In the machine coarse filter, manual cleaning is required. [0003] Such as figure 1 As shown, the existing dishwasher is provided with a water tank 100 on the inner tank of the machine, and the water tank 100 is provided with a coarse filter 200 as a ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the existing technology has the following defects: 1) Two separate pumps are required for washing and drainage, which takes up a lot of space, and both pumps need to be driven by motors. The two motors not only take up a lot of space but also have high costs; The residue needs to be cleaned by the user, which is cumbersome; 3) The structure of the crushing blade is complicated when it is installed on the washing motor shaft, and the crushed food residue and water circulate together during washing and it is easy to block the sprinkler; 4) The power of the drainage motor is small, The crushing effect is poor when the blade is installed on the shaft of the drainage motor; 5) The washing pump or drainage pump is usually installed horizontally, so that sewage is easy to remain in the pump casing, which is not good for the washing effect
