Fruit and vegetable cleaning machine

Abstract

The invention relates to a fruit and vegetable cleaning machine which comprises a box body, a water pumping mechanism and a water storage box; the water storage box is arranged on the outer bottom wall of the box body, a water outlet is formed in the top of the water storage box, and a water passing opening corresponding to the water outlet is formed in the bottom wall of the box body; the water pumping mechanism comprises a spraying arm, an impeller assembly and a motor; the spraying arm is arranged at the bottom of the washing cavity, a water inlet corresponding to the water passing openingis formed in the bottom wall of the spraying arm, the impeller assembly is rotatably arranged in the water storage box, the upper portion of the impeller assembly penetrates through the water inlet toextend into the spraying arm, the motor is arranged at the bottom of the water storage box, and an output shaft penetrates through the bottom wall of the water storage box to be connected with the impeller assembly. An output shaft of the motor is hollow so as to form an air guide pipe for adding air into water flow in the washing cavity. The water storage box serves as a water return area, compared with an existing draining area, the size is smaller, and the water consumption for washing each time can be greatly reduced; water flow be aerated through the hollow output shaft of the motor, bubbles are entrained in the water flow, the bubbles are broken on the surface of a cleaned object, the dirt stripping force can be improved, and therefore the cleaning effect is improved.

Description

technical field [0001] The invention relates to a fruit and vegetable cleaning machine. Background technique [0002] Existing dishwashers, fruit and vegetable cleaning machines, etc., are a device that sprays cold or hot water onto dishes, fruits and vegetables, etc. to remove dirt adhering to dishes, fruits and vegetables, and dishes, fruits and vegetables usually include Pumps and nozzles that spray wash water. [0003] Common dishwashers generally use a water pump to lift water and spray it to the fruits and vegetables in the cleaning space to achieve the cleaning effect, or drive the cleaning basket to rotate and spray water into the cleaning basket from top to bottom. Fruits and vegetables can be rinsed. There is also a structure in which fruits and vegetables soaked in water are cleaned by turbulent water flow. [0004] For example, the Chinese patent application "A Spray Arm and a Cleaning Machine Using the Spray Arm" with the application number CN201710714387.0 p...

Problems solved by technology

However, for fruit and vegetable cleaning, there are often a lot of silt and residual leaves attached to the surface of fruits and vegetables, and the movement mode of pollutants such as fruit and vegetable debris is mainly with the flow movement. It is arranged eccentrically in the draining area at the bottom of the tank, and the slag is only brought into the slag basket by the natural flow of water when collecting the slag, which makes it easy for pollutants to deposit at the corners of the tank, making it difficult to clean

There are often pesticide residues on the surface of fruits and vegetables, and ordinary turbulent water flow is not thorough enough to remove pesticide residues

[0005] In addition, the drainage area is used as the backwater area, which is affected by the installation method and position of the functional components at the bottom of the sink. The volume of the drainage area is relatively large. In order to meet the required water level, the water consumption for each washing is relatively large.
