Description

Dish washing machine

Technical Field

The utility model relates to the technical field of dish washing machines, in particular to a dish washing machine capable of preventing a washing pump from trapping air.

Background

The dish washing machine has wide application in occasions such as restaurants, homes and the like, can save labor force and improve the cleaning efficiency of kitchen bowls and the like. The dish washer is provided with a shell, an inner container is arranged in the shell, a water tank and a washing pump communicated with the water tank are arranged at the bottom of the inner container, a spraying device is arranged at the top and/or the middle and/or the bottom of the inner container, and a water outlet of the washing pump is communicated with the spraying device through a water leading pipeline. When the washing machine works, water enters the water tank through the water inlet pipe, the washing pump absorbs water from the water tank after a certain amount of water is reached, water is supplied and pressurized, the pressurized water enters the water diversion pipeline after passing through the water diversion valve from the water outlet of the washing pump and is guided to the spraying device at the corresponding position, and then washing of bowls and the like is achieved.

In order to improve the washing efficiency, the demand of the dish washing machine with large capacity is increasing, and the prior art generally realizes the large capacity by increasing the space of the inner container. Under the premise that the volume of the shell of the dishwasher is fixed, the increase of the space of the inner container means that the installation space of parts such as a water tank, a washing pump and the like is reduced, and the height difference between the washing pump and the water inlet of the water tank is easily caused. In the water inlet process of the dish washing machine, along with the continuous rising of the water level of inlet water, air in the washing pump is continuously discharged, but after the water level reaches a certain liquid level, water continues to enter due to the height difference, and the air on the upper part of the washing pump cannot be discharged, so that the air trapping phenomenon occurs in the washing pump. When the washing pump works, the inside of the washing pump is in a gas-liquid mixing state, and trapped gas can cause the hydraulic performance (water volume and water pressure) of the washing pump to be greatly reduced, so that the normal operation of the washing pump is influenced, and the performance of the dish washing machine is reduced.
