Noise-lowering type kitchen refrigeration extractor hood

Abstract

A noise-lowering type kitchen refrigeration extractor hood comprises a case, a lampblack suction opening and a lampblack exhaust opening. A lampblack suction channel communicating with the lampblack suction opening and the lampblack exhaust opening is arranged in the case, and a fan is arranged in the lampblack suction channel. An air outlet is formed in the case, and a refrigeration device for cooling air blown out of the air outlet is arranged in the case. The refrigeration device comprises a refrigeration assembly with a cold end and a hot end, the cold end is located outside the lampblacksuction channel, and the hot end is arranged in the lampblack suction channel. A microporous heat radiation plate is mounted at the hot end. According to the refrigeration extractor hood, the hot endof the refrigeration assembly of the refrigeration device is arranged in the lampblack suction channel, a fan system can be utilized for effectively cooling the hot end of the refrigeration device, and an outdoor unit does not need to be additionally arranged. The structure is compact, the integration level is high, and cost is reduced. In addition, the microporous heat radiation plate is mountedat the hot end, so that the heat radiation area in contact with air is increased, the heat radiation effect is greatly enhanced, and the function of micropore noise lowering can be achieved.

Description

technical field [0001] The invention relates to a range hood, in particular to a noise reduction type kitchen refrigeration range hood. Background technique [0002] With the improvement of material living standards, people have higher and higher requirements for the kitchen environment. During the cooking process, the use of the stove will generate a lot of heat in the kitchen, resulting in an increase in the temperature of the entire kitchen space and a decrease in the comfort of the environment. . At present, most families solve this problem by temporarily adding fans, but this method is not only inconvenient, but also takes up the kitchen area. To solve this problem, in the prior art, a refrigeration module is generally added to the range hood to realize the purpose of delivering cold air to the kitchen and improving the comfort of the environment. The refrigeration module of existing products either adopts semiconductor refrigeration, or adopts a refrigeration cycle s...

AI Technical Summary

Problems solved by technology

Although the air curtain range hood can effectively deliver cold air to the kitchen, its semiconductor refrigeration system has a complex structure, especially the hot-end heat dissipation part, which needs to be equipped with a hot-end air duct and a fan for heat dissipation, which not only limits the heat dissipation, but also increases energy consumption. consumption, but also increases the volume of the smoke exhaust duct of the range hood, and the relative cost is relatively high, and this hot-end heat dissipation structure has no effect on reducing the noise of the range hood

In addition, the existing air conditioners cannot be widely used in the kitchen, because the greasy environment in the kitchen is likely to cause the blockage of the cooling air duct, and the internal circulation air conditioner cannot achieve a good cooling effect when the hood is turned on, and the If you install an air conditioner indoors, you must face the trouble of installing an outdoor unit
