Cleaning machine

Abstract

The invention relates to a cleaning machine. The cleaning machine comprises a water tank body, a spraying arm, a motor, a motor shaft, a centrifugal impeller, a water supply mechanism and a diversionpart; the centrifugal impeller is arranged in the spraying arm, and connected with the upper end of the motor shaft; the motor shaft is through vertically; furthermore, the lower end is connected withthe water supply mechanism; the diversion part is arranged below the spraying arm, and connected with a water inlet; multiple diversion holes are arranged on the outer circumferential wall of the lower part of the diversion part at intervals; and the upper part of the diversion part is provided with a valve assembly, which can close the lower end of the water inlet when the motor shaft inputs water into the spraying arm and open the lower end of the water inlet when the centrifugal impeller is started. When in use, the water inlet is closed through the valve assembly at first; the motor shaftinputs a little water into the spraying arm, so that the centrifugal impeller is immersed; after the centrifugal impeller is started, water supply of the motor shaft is stopped; under the action of negative pressure, a water flow continuously enters the diversion part, and drives the valve assembly to open the water inlet; therefore, continuous supply of the water flow is realized; due to positive and negative rotation of the motor, bidirectional rotation of the spraying arm can be realized; and thus, the cleaning effect is increased.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine with a spray arm capable of bidirectional rotation. 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. Dishwashers currently on the market are generally divided into three types: table type, cabinet type, and tank type. Among them, the table type dishwasher is an integral independent structure, which is generally placed on the table for use; , but needs to be embedded in the kitchen cabinet for use; the sink dishwasher is combined with the sink and is generally installed in the kitchen cabinet for use. [0003] For example, according to the structure disclosed in the Chinese patent "Sink Type Cleaning Machine" (application number: CN2013749864.9) whose authorized announcement number is CN3735237B, the sink type cleaning machine include...

AI Technical Summary

Problems solved by technology

After the water touches the dishes, the impact force will be relatively attenuated. When the spray arm can only rotate in one direction, it is easy to clean one side of the dishes, but the other side is not clean.
