Water pumping mechanism for cleaning machine

Abstract

The invention relates to a water pumping mechanism for a cleaning machine, which comprises a spraying arm, an impeller assembly and a water guide box, wherein a first water inlet is formed in the lower wall face of the spraying arm, the water guide box is provided with an upper cavity and a lower cavity which are vertically communicated, a second water inlet is formed in the bottom of the lower cavity, a first water outlet communicated with the first water inlet of the spraying arm is formed in the top of the upper cavity, the upper part of the impeller assembly is rotatably arranged on the lower part of the lower cavity and the lower part of the upper cavity, a space guide impeller capable of guiding water in the lower cavity upwards is further arranged in the upper cavity, and a second water outlet for water output is formed in the side portion of the lower cavity. The impeller assembly is used for pumping water into the water guide box and providing power for water flow to be pumped into the spraying arm and directly pumped out from the side part of the water guide box, and the side part of the water guide box can be connected with a water spraying structure guiding upwards, so that upper-lower-layer double-layer spraying is achieved, the spraying range is enlarged, and the cleaning effect is improved; and the space guide impeller can reduce energy loss in the upward flowing process of water flow, and large and stable water flow of the upper layer is kept.

Description

technical field [0001] The invention relates to a pumping mechanism for a washing machine. Background technique [0002] Along with improving day by day of people's living standard, dishwasher more and more enters family as a kind of kitchen appliance product.
