Dishwasher condensation drying system, condensation drying method and dishwasher

Abstract

The invention relates to the field of dishwashers, in particular to a dishwasher condensation drying system, a condensation drying method and a dishwasher. The dishwasher has an inner container enclosing a washing chamber. The condensation drying system comprises an air exhaust device and a collection chamber used for collecting air in the washing chamber. The collection chamber is provided with an air outlet, the air exhaust device comprises a housing and a fan arranged in the housing, one end of the shell is communicated with atmospheric air and the other end is communicated with a condensation chamber. An air outlet of the collection chamber is communicated with the housing, and the fan is arranged at one end of the housing distant from the condensation chamber and the air outlet. An openable air separator is arranged in the air outlet. When the air separator is opened, the collection chamber is communicated with the housing, and the fan can guide external air and humid air in the washing chamber into the condensation chamber. Cold drying air outside and hot humid air can enter the condensation chamber to significantly improve drying and condensation efficiency. In addition, humid air has no need to pass the fan and thereby has no damage to the electric control system of the fan.

Description

technical field [0001] The invention relates to the field of dishwashers, in particular to a dishwasher condensation drying system, a condensation drying method, and a dishwasher. Background technique [0002] In recent years, with the improvement of living standards, dishwashers have become popular in people's daily life and have gradually become an indispensable electrical appliance in the kitchen. However, due to the increase in the variety and quantity of dishwashers on the market, consumers have higher and higher quality requirements for dishwashers. [0003] After the dishwasher has cleaned the tableware, it needs to dry the tableware, which requires removing the humid air in the inner container. Therefore, in the drying stage, it is necessary to change the humid air in the washing chamber (inner tank) into dry air, so as to achieve the purpose of drying the tableware. [0004] In the prior art, there are three main solutions for changing the humid air in the washing...

AI Technical Summary

Problems solved by technology

Specifically, the humid hot air convected in the condensing chamber exchanges heat with the outside air through the condensing chamber wall, and the incoming hot humid air will be condensed into water droplets and flow back to the bottom of the washing chamber to achieve the purpose of drying , but this method has a disadvantage: using natural convection, the drying efficiency is very low, and the second is that heat exchange is required across the condensation chamber wall, which further reduces the drying efficiency

But this method only accelerates the convection, and still exchanges heat through the wall of the condensation chamber, and the humid air in the tank needs to pass through the fan, which will damage the electric control system of the fan and affect the life of metal and electronic components.

[0008] Based on the above description, there is an urgent need for a new condensation drying system and its dishwasher to solve the problem in the prior art that the humid air needs to pass through the fan and damage the electric control system of the fan.
