Internal circulation drying system for dish washing machine

Abstract

The invention discloses an internal circulation drying system for a dish washing machine. The system comprises: an inner container, wherein a wind outlet is formed in the side wall of the inner container; a water cup provided with a water collecting cavity and a water chamber, wherein the water collecting cavity is communicated with the inner container, the water chamber is provided with a gas inlet hole and a gas permeable hole which are respectively communicated with the water chamber, and the gas permeable hole is communicated with the inner container and / or the water collecting cavity; and a wind channel assembly comprising a condensation wind channel and a gas conveying device, wherein the two opposite ends of the condensation wind channel communicate with the gas outlet and the gas inlet hole correspondingly, and the gas conveying device is arranged on the condensation wind channel or arranged between the condensation wind channel and the gas inlet hole. According to the invention, wet and hot gas is internally circulated, and a water chamber is additionally arranged in the circulating drying system for ventilation to condense water vapor of the wet and hot gas, so that the drying function is achieved while the problem that condensed water appears when the gas is exhausted out of the inner container is solved.

Description

technical field [0001] The invention relates to the technical field of dishwashers, in particular to an internal circulation drying system for dishwashers. Background technique [0002] In order to improve the tableware drying effect of the dishwasher after washing, some dishwashers have been equipped with a ventilation system. The air is sucked into the inner tank, which can effectively promote the drying effect of the tableware. However, this drying system has the following problems: [0003] 1. Since the exhaust is hot and humid gas rich in steam, it is easy to condense into water droplets at the air outlet, and a large number of water droplets drip from the air outlet, which not only affects the user's experience, but may also cause water leakage to the user misunderstanding; [0004] 2. The temperature of the external air pumped into the inner tank is relatively low, which will mix with the hot and humid gas near the air inlet, instead causing some steam to condense ...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the exhaust is hot and humid gas rich in steam, it is easy to condense into water droplets at the air outlet, and a large number of water droplets drip from the air outlet, which not only affects the user's experience, but may also cause water leakage to the user misunderstanding;

[0004] 2. The temperature of the external air pumped into the inner tank is relatively low, which will mix with the hot and humid gas near the air inlet, instead causing some steam to condense on the side wall of the inner tank, bowl basket and tableware, affecting the drying efficiency;

[0005] 3. In order to increase the temperature of the air intake, a heater is added in the air intake duct, but heating the air will generate higher energy consumption, which is not conducive to energy saving;

[0006] 4. The air inlet is connected to the external atmosphere, and to a certain extent, some bacteria or viruses floating in the air may be brought in when the air enters, which will cause secondary pollution of the tableware
