Cleaning machine

Abstract

The cleaning machine comprises a water tank body and a spraying arm, wherein a water falling opening is formed in a bottom wall of the water tank body, a water storage tank is arranged below the water tank body, an opening communicated with the water falling opening is formed in the top wall of the water storage tank, and a water pumping assembly used for pumping water into the spraying arm from the water storage tank is further arranged on the water tank body; and a filtering piece capable of filtering water entering the water storage tank and the spraying arm is connected between the water falling opening and the water inlet of the spraying arm. When water flow is drawn upwards, bubbles carried in the water flow can be discharged from the edge of the water falling opening, a large number of bubbles are prevented from being pumped into the spraying arm along with water, the water pumping assembly keeps high power and lift, and the cleaning effect is improved; only one water falling opening is formed in the bottom wall of the water tank body, so a bottom structure of the water tank body is greatly simplified, and disassembly, assembly and later maintenance are facilitated; meanwhile, the food residues can be adsorbed on the peripheral wall of the filter part, so food residues are prevented from being retained at other parts of the water tank body, and centralized collection and cleaning are facilitated.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a washing machine for washing dishes, fruits and vegetables. Background technique [0002] With the increasing improvement of people's living standards, dishwashers, as a kitchen appliance product, are increasingly entering the family. At present, dishwashers on the market are generally divided into three types: desktop type, cabinet type, and tank type. Among them, the desktop dishwasher is an integral independent structure, which is generally placed on the countertop for use; the cabinet type dishwasher is also an independent structure. , but it needs to be embedded in the kitchen cabinet; the trough dishwasher is combined with the sink and is generally installed in the kitchen cabinet. [0003] The structure of the sink type washing machine currently on the market is mainly the structure mentioned in the applicant's previous application CN201310750968.1 "Sink Type ...

AI Technical Summary

Problems solved by technology

[0004] The concave draining area on the above-mentioned sink body needs to be obtained by secondary drawing on the bottom of the sink body during production, and the forming process is extremely complicated; moreover, the liquid level of the washing machine fluctuates greatly during the cleaning process, and the liquid containing detergent The water flow is very easy to foam, and the draining area is used as the return area of ​​the washing machine. When the liquid level is lower than the draining plate, the gas will enter the draining area, and as the water continues to flow into the draining area, the air bubbles will also be trapped under the draining plate. Elimination, which makes the gas-liquid exchange in the draining area strong, and the air bubbles easily enter the pump cavity with the water flow, resulting in a rapid drop in pump power, a rapid decrease in the water head of the spray arm, and even unable to meet the basic cleaning needs; heating plate, water pump, drain Distributed isolated on the bottom of the sink body, difficult to install and maintain

In addition, because the slag basket in the existing sink type washing machine is arranged on the side of the central part of the sink body, and close to the gravity of the water, the concentration effect of the food residues is poor, and some food residues tend to stay in the sink body Difficult to clean at the output shaft of the water pump in the center of the bottom
