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

Embodiment 1

[0035] refer to figure 1 , this embodiment provides an internal circulation drying system for a dishwasher, including an inner container 1, a water cup 2, an air duct assembly (not shown in the figure) and a controller (not shown in the figure). The side wall of the inner liner 1 is provided with an air outlet 11 through which hot and humid gas passes. The water cup 2 is arranged at the bottom of the inner container 1 and is provided with a water collection chamber 21 and a water chamber 22 , and the water collection chamber 21 is connected to the inner container 1 . The water chamber 22 has an air intake hole 221 and a vent hole 222 respectively communicating with it, the vent hole 222 is used for air and / or water to pass through, and the vent hole 222 communicates with the inner tank 1 and / or the water collection chamber 21, that is, the water chamber 22 The vent hole 222 of the water chamber 22 can directly only communicate with the inner bag 1, or the vent hole 222 of the...

Embodiment 2

[0059] refer to Image 6 , The difference between this embodiment and Embodiment 1 is that a water vapor isolation structure 8 is provided in the water chamber 22 , and the water vapor isolation structure 8 is located above or below the vent hole 222 . Thus, through the water vapor isolation structure 8, the water content of the gas flowing from the vent hole 222 to the inner container 1 can be reduced, and the drying effect can be further improved.

[0060] Specifically, the water vapor isolation structure includes a water vapor isolation net 81, and the water vapor isolation net 81 can be arranged in the water chamber 22 and between the air inlet 221 and the air vent 222, or attached to the bottom of the air vent 222, or arranged on the air vent 222. Between the hole 222 and the liner 1 .

[0061] When the water vapor isolation net 81 is arranged in the water chamber 22, the water vapor isolation net 81 is arranged in the water chamber 22, and it divides the water chamber 2...

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 ...
