Description

Cleaning machine

Technical Field

The present invention relates to a cleaning machine, and more particularly, to a cleaning machine capable of generating bubbles in a fluid to thereby enhance a cleaning effect.

Background

With the increasing level of living of people, dish washers are increasingly entering home as household electrical appliances for kitchen use. The existing dish-washing machines on the market are generally divided into three types of a desk type dish-washing machine, a cabinet type dish-washing machine and a trough type dish-washing machine, wherein the desk type dish-washing machine is of an integral independent structure and is generally placed on a desk for use; the cabinet type dish washer is also an independent structure, but needs to be embedded into a kitchen cabinet for use; the tub dishwasher is combined with a tub and is generally installed in a kitchen cabinet.

The dish washing machine of the above-mentioned various forms generally has a washing function by lifting water by a water pump and spraying the water toward dishes in a washing space. For example, the chinese patent with application number CN97236119.7, i.e. a microcomputer light-operated full-automatic dish washer, and the chinese patent with application number CN00240098.7, i.e. a dish washer, all disclose similar structures, in which the impact force of water flow sprayed to the dishes is weak and not uniform enough, and when the number of dishes is large, the water flow cannot be covered, resulting in poor cleaning effect. The chinese patent with application number CN200710306898.5, "dish washing machine, especially household dish washing machine, provided with a device for improving decontamination effect" provides a vaporizing device for generating a fluid mist that can be introduced into a dish washing machine cavity to expand the washing area of the dishes and improve the uniformity of the washing medium, but such a structure still cannot solve the problem of weak impact force of the sprayed water flow. The Chinese patent with the application number of 201610795828.X, namely a large-scale ultrasonic automatic dish washer, is provided with an ultrasonic emission head device, high-pressure air is input into a cleaning liquid at the same time, the input high-pressure air forms bubbles in the cleaning liquid by utilizing the ultrasonic emission head device, and an ultrasonic transducer is used for providing energy for the cleaning liquid, so that the bubbles in the cleaning liquid are broken to generate impact force, and the impact force of water flow is improved. However, in such a structure, the instantaneous cavitation phenomenon generated between the ultrasonic wave and the high-pressure air bubbles needs to be maintained in water, and when the water flow is lifted by the water pump and is circularly sprayed out, the high-pressure air bubbles are difficult to reach the surfaces of the dishes, and then break, so that the structure is not suitable for the structure of the water flow spraying type dish washing machine. In addition, the structure is only suitable for large-scale dish washers, and is difficult to be suitable for household dish washers.
