Range hood external temperature variable module and range hood

Abstract

Disclosed are an external range-hood temperature-varying module and a range hood. The temperature-varying module comprises: a module shell including a hollow chamber and heat-exchanging air inlets, and heat-exchanging air outlets; and a semiconductor temperature-varying device including a semiconductor chilling plate arranged in the module shell and first and second heat-exchanging systems contacting first and second temperature-varying surfaces of the semiconductor chilling plate, wherein the first heat-exchanging system is at least partially arranged between the heat-exchanging air inlets and outlets, and the second heat-exchanging system includes a plurality of second heat pipes contacting the second temperature-varying surface and a first heating panel. The first heating panel extends out of the module shell and contacts a housing of the range hood and a plurality of third heat pipes; the third heat pipes contact two second heating panels; and the two second heating panels contact the housing of the range hood. The temperature-varying module is integrated in the housing of the range hood to form the range hood. The temperature-varying module is simple in structure and low in cost, can be integrated in the housing of the range hood without affecting an inner structure of the housing of the range hood, and is easy to clean, maintain, and assemble and disassemble.

Description

technical field [0001] The invention relates to a range hood, in particular to an external temperature-variable module of a range hood and a range hood using semiconductor refrigeration and heating. Background technique [0002] Cooking beside the kitchen stove is a hard housework, especially in summer. The hot weather and the heat from the stove make the working environment in the kitchen very harsh. [0003] In order to solve the problem of overheating in the kitchen, some people install fans or air conditioners in the kitchen. However, the cooling effect of fans is average, and it will affect the normal operation of the gas stove, and there are also potential safety hazards. Due to the special lampblack environment in the kitchen, after the fan has been used for a period of time, a large amount of putty is attached to the fan, which is difficult to clean and also causes pollution to the kitchen environment. [0004] The installation of air-conditioning equipment in the k...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of high temperature in the kitchen, some people install fans or air conditioners in the kitchen. However, the cooling effect of the fan is not good, and it will affect the normal operation of the gas stove, and there are also potential safety hazards.

Due to the special oil fume environment in the kitchen, after the fan is used for a period of time, a large amount of putty will adhere to the fan, which is difficult to clean and will also cause pollution to the kitchen environment

[0004] Installing air-conditioning equipment in the kitchen, on the one hand, has the problem of cost, on the other hand, there will also be the problem that it is difficult to clean. After the oil fume is attached to the surface of the air-conditioning heat exchanger, there is also the problem that the cooling effect will decrease.
