Description

Cleaning machine

Technical Field

The invention relates to the technical field of household appliances, in particular to a cleaning machine for cleaning dishes, fruits and vegetables.

Background

A dishwasher is an apparatus that sprays cold or hot water to dishes to remove dirt adhered to the dishes and wash the dishes. Dishes are placed in a dish frame inside a dish washing cabinet, and a general dish washing machine includes a pump and a spray head to spray washing water, a heater to generate hot water, and the like. Such a dishwasher usually requires a separate housing and separate components, so that the general dishwasher is large in volume and is not suitable for being used in some families with large population and small living area, and thus the dishwasher is not common in many families.

In order to save space and expand the application range, many designs of water tank type cleaning machines have been developed, that is, the existing water tank is modified into a cleaning machine, the water tank is directly used as a washing space, and a rotary spray arm is generally arranged at the bottom of the water tank and is generally connected with a pump body driven by a motor.
