Fresh air linkage controller and range hood using same

Abstract

The invention relates to a fresh air linkage controller and a range hood using the same. When the range hood is turned on, a current inductive circuit automatically senses the working current of the range hood and outputs an electric signal to start a drive and control circuit; the drive and control circuit is started to automatically open a fresh air electrically operated valve; the fresh air electrically operated valve is enabled to perform forward rotation to open a fresh air valve, at the moment under negative pressure suction of the range hood, fresh air enters indoor from outdoor through the fresh air valve, the kitchen is timely supplemented with the fresh air, the range hood is more labor-saving in suction and discharge, the inlet air of the range hood is increased, the diffusion of exhaust gas and cooking fume is reduced, and the purpose of improving the air quality of the kitchen is achieved; besides, the design is reasonable and ingenious, high safety and reliability are achieved, the use is convenient, the cost is low, and the popularization and application are facilitated.

Description

technical field [0001] The invention relates to a fresh air linkage controller and a range hood using the fresh air linkage controller. Background technique [0002] With the continuous improvement of people's living standards, the pursuit of quality of life is getting higher and higher, especially the health awareness is becoming stronger and stronger. In the kitchen, most of the exhaust gas generated by the combustion of the stove and the oil fume generated by cooking are sucked and exhausted outside by the range hood, but it is always difficult to discharge cleanly, and the escaped exhaust gas and oil fume will float in the room space. If there is not enough fresh air to fill in and only rely on air leakage from doors and windows, the escape of oil fume will be more serious, and the air pollution in the kitchen will be more serious, which will affect people's health. Contents of the invention [0003] The purpose of the invention is to improve the air quality of the ki...
