Internal circulation drying system for household dishwasher

Abstract

The invention provides an internal circulation drying system for a household dishwasher and belongs to the technical field of dishwashers. The technical problems that drying systems of existing dishwashers have complicated structures and energy cannot be saved are solved. The dishwasher includes an inner container, and the internal circulation drying system includes a circulation pipeline and a drying assembly. Both ends of the circulation pipeline can be communicated with the inner container separately to form an internal circulation passage, and the drying assembly is disposed in the middleof the circulation pipeline and can perform drying treatment on air passing through the internal circulation passage. The internal circulation drying system for the domestic dishwasher has the advantages of achieving efficient drying of bowls and chopsticks, saving energy and not causing secondary pollution to the bowls and the chopsticks.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and relates to a drying system for dishwashers, in particular to an internal circulation drying system for household dishwashers. Background technique [0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, plates, knives, and forks. Fully automatic dishwashers on the market can be divided into two types: household and commercial. Household fully automatic dishwashers are only suitable for households, mainly including cabinet type, desktop type and integrated sink type. [0003] The current dishwashers generally dry the bowls and chopsticks in the dishwasher after washing, and quickly dry the moisture on the bowls and chopsticks. The existing dishwashers are equipped with heating components to heat the air. Air to quickly dry the moisture on the tableware. For example, the dishwasher drying equipment disclosed in the Chinese patent literature...

AI Technical Summary

Problems solved by technology

Existing dishwasher heating components are mainly implemented in a way similar to air-conditioning heating. Therefore, it is necessary to introduce external air, heat the external air and transport it to the inside of the dishwasher for hot air drying. Due to the need to introduce external Air, so it is necessary to filter the air, which requires a filter system, and the existing filter system is difficult to filter the super tiny particles and bacteria, so it will cause secondary pollution to the washed dishes; enter through hot air Finally, with the evaporation of water, the air humidity in the dishwasher will increase, and the increase in humidity will reduce the evaporation efficiency of water, resulting in low drying efficiency; further, because some of the hot air will be discharged out of the dishwasher after entering. , it is necessary to continuously heat the air to ensure the high temperature of the air in the dishwasher, so the compressor needs to work continuously and intensively, resulting in high energy consumption of the dishwasher, which is not energy-saving and environmentally friendly
