Fruit and vegetable cleaning machine

Abstract

The invention relates to a fruit and vegetable cleaning machine. The fruit and vegetable cleaning machine comprises a box body, a spraying arm and an impeller assembly; the impeller assembly comprisesa supporting sleeve, an inner wheel and an outer wheel; the first end of the supporting sleeve is supported on the bottom wall of the box body and provided with a second water inlet; a first water outlet connected with a first water inlet of the spraying arm is formed in the second end of the supporting sleeve; the inner wheel has a centrifugal structure and can be rotationally arranged in the supporting sleeve; and the outer wheel is arranged between the supporting sleeve and the inner wheel in a sleeving mode, and at least the upper part of the outer wheel forms a flow guide structure capable of guiding water flow upwards. The double-impeller structure is adopted; the inner wheel is a centrifugal impeller, and can convert all power of a power mechanism into centrifugal dispersion forceof the water flow; the outer wheel is fixed to the periphery of the inner wheel, and provides an upward guiding path for the water flow; and the outer wheel does not need to consume the power, so thatthe capacity loss is reduced, the acting of the impeller on the water flow is increased, the water flow speed and the water pressure at the outlet of the spraying arm are increased, the turbulence degree of the water flow is improved, and the fruit and vegetable cleaning effect is improved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a fruit and vegetable cleaning machine. Background technique [0002] At present, the cleaning of fruits and vegetables by the fruit and vegetable cleaning machine is mainly realized by the turbulent flow in the fruit and vegetable tank. The size of the turbulent flow in the fruit and vegetable tank basically determines the cleanliness of the fruit and vegetable cleaning, and the generation of turbulent flow mainly relies on the high-speed rotation of the blades to generate high-pressure water flow. , the water pressure into the spray arm determines the strength of the turbulent flow. [0003] The Chinese utility model patent "Spray Type Sink Fruit and Vegetable Cleaning Machine" (application number: CN201721886115.0) with the authorized announcement number CN208659054U discloses a fruit and vegetable cleaning machine structure, in which the structure of the impeller a...

Problems solved by technology

With this type of single impeller structure, the axial flow structure at the lower part of the impeller only provides power for the uploading of the water flow, while the flow rate and pressure of the water are provided by the centrifugal structure at the upper part of the impeller. As a result, the work done by the single impeller on the water flow is limited, and the degree of turbulence generated by the water sprayed by the spray arm is small, which limits the cleaning effect on fruits and vegetables to a certain extent.
