Description

Cleaning machine and cleaning method thereof

Technical Field

The invention relates to a cleaning machine and a cleaning method thereof, wherein the cleaning method is particularly suitable for cleaning fruits and vegetables.

Background

With the increasing living standard of people, the dish washing machine is used as a kitchen household appliance and is more and more introduced into families. The dish-washing machines on the market at present are generally divided into a table type dish-washing machine, a cabinet type dish-washing machine and a trough type dish-washing machine, wherein the table type dish-washing machine is an integral independent structure and is generally placed on a table top for use; the cabinet type dish washing machine is also an independent structure, but needs to be embedded into a kitchen cabinet for use; the sink dishwasher is combined with a sink and is generally installed in a kitchen cabinet for use.
