Exhaust hood with gas leakage alarm device

Abstract

The invention discloses an exhaust hood with a gas leakage alarm device and belongs to the technical field of kitchen appliances. The exhaust hood with the gas leakage alarm device comprises an exhaust hood unit, a gas leakage protection unit and a central processing unit, wherein the exhaust hood unit comprises an exhaust hood controller used for starting lampblack discharge and a smoke ventilator; the gas leakage protection unit comprises the gas leakage alarm device; and the central processing unit is used for controlling operation of the exhaust hood unit, the gas leakage protection unit and a semiconductor refrigerating unit. The gas leakage alarm device detects the gas content in air in real time after being started. If gas leakage is detected, the gas leakage alarm device gives an alarm signal. The exhaust hood controller receives the alarm signal and transmits the alarm signal to the central processing unit. The central processing unit controls the exhaust hood controller to start. The exhaust hood controller controls the smoke ventilator to discharge gas outwards. At the same time, the gas leakage alarm device continues to detect the gas content until gas cannot be detected, and then the smoke ventilator is stopped. The exhaust hood with the gas leakage alarm device, discloses by the invention, has the advantage that the gas detection function and the refrigerating function are achieved.

Description

Technical field: [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood with a gas leakage alarm. Background technique: [0002] With the continuous improvement of people's living standards and living conditions, range hoods have become an indispensable household appliance in the kitchen. At present, the space of the kitchen in the general family is relatively small and crowded. People need to use stoves in the process of cooking, which will inevitably generate a lot of heat in the kitchen, leading to an increase in the temperature of the entire kitchen interior space, making the kitchen environment less comfortable, especially in summer, people cooking in such an environment will The heat is unbearable, which affects the mood of cooking, greatly reduces the taste of dishes, and affects people's quality of life. [0003] In addition, with the acceleration of life festivals, when people use gas stoves, due to various reasons...

Problems solved by technology

People need to use stoves in the process of cooking, which will inevitably generate a lot of heat in the kitchen, leading to an increase in the temperature of the entire kitchen interior space, which reduces the comfort of the kitchen environment, especially in summer. The heat is miserable, which affects the mood of cooking, greatly reduces the taste of dishes, and affects people's quality of life

[0003] In addition, with the acceleration of living festivals, when people use gas stoves, due to various reasons, there will be gas leakage, or the gas pipeline will be corroded, resulting in gas leakage, etc., and the concentration of carbon monoxide in a space exceeds a certain value. When it encounters an open flame, an explosion will occur, and the consequences will be disastrous
