Description

A exhaust subassembly and cleaning machine for cleaning machine

Technical Field

The utility model belongs to the technical field of household washing, and particularly relates to an exhaust assembly for a cleaning machine and the cleaning machine.

Background

A washing machine, which is a household appliance for automatically washing tableware, is popular with consumers, and generally performs at least two washing processes during which at least one washing process uses hot water for washing the tableware. This results in a significant amount of water vapor remaining in the wash chamber after cleaning, which condenses and collects on the surface of the dishes, although drying is accomplished by the waste heat of the liner and dishes. However, as the residual water in the inner container is more and the inner container is cooled faster, the residual heat in the inner container is insufficient to evaporate the residual water, so that the inner container still has more water in a long time after the bowl is washed, and the peculiar smell in the dish washing machine is heavier and bacteria are easy to breed under the condition that the door body of the dish washing machine is tightly closed for a long time.

In order to solve the above technical problems, for example, chinese patent application No. ZL201820048307.2 (grant publication No. CN 208435585U) discloses a drying module, which includes: the first air duct is provided with a first air inlet and a first air outlet; the second air duct is provided with a second air inlet and a second air outlet, and the second air outlet is positioned at the bottom of the dish washer; the airflow driving piece is used for driving airflows in the first air duct and the second air duct; the refrigerating piece is provided with a cold end and a hot end, the cold end of the refrigerating piece exchanges heat with the first section of the first air duct, the hot end of the refrigerating piece exchanges heat with the second section of the first air duct and the second air duct, and air flow flowing in through the second air inlet flows out to the outside through the second air outlet.

The second air outlet (air outlet) is arranged at the bottom of the dish washer, and has the following defects:

1. in the initial stage of drying, the heat of the discharged gas is high, and potential safety hazards exist for users;

2. in the drying process, a large amount of hot and humid gas is discharged downwards, so that water marks are easily formed on the ground in front of the exhaust port, the ground becomes wet and slippery, and potential safety hazards exist;

3. in the drying process, water drops can be condensed in the exhaust assembly (the second air duct) and drop to a cabinet or the ground along the exhaust port.

Accordingly, there is a need for further improvements to existing exhaust assemblies.
