Problems solved by technology

[0003] However, in cold weather, when the installed air outlet does not need to work, due to the temperature difference between indoor and outdoor, the outdoor cold air will enter the room, thereby causing heat loss in the house and affecting people's daily life.
Especially in the northern cold regions, the impact is particularly obvious, and it does not meet the requirements of emerging energy-saving houses for indoor heat loss

Abstract

The invention discloses an exhaust hood air supplement linkage device comprising an exhaust hood body, an electric air valve, a linkage controller, a starting switch and a power supply circuit; the linkage controller comprises a sensor, a signal processing circuit and a controllable switch; the sensor is arranged on an exhaust hood power supply circuit, and the sensor is used for sensing electricsignals generated on the exhaust hood power supply circuit and outputting the electric signals after sensing the electric signals; the signal processing circuit is separately connected with the sensorand the controllable switch, and the signal processing circuit is used for receiving the signals outputting from the sensor and controlling the controllable switch according to the signals; the controllable switch is arranged on an electric air valve power supply circuit and is controlled by the signal processing circuit, and the controllable switch is used for controlling the electric air valvepower supply circuit in a closed or disconnected state. The linkage controller is adopted, when the exhaust hood works normally, the electric air valve is opened in a linkage mode to provide fresh airfor indoors, moreover, when the exhaust hood stops working, the electric air valve is closed in a linkage mode to prevent fresh air from entering the room.

Description

technical field [0001] The present application relates to a range hood, in particular to a range hood supplementary wind linkage device. Background technique [0002] When the kitchen range hood is working, a large amount of air needs to be exhausted from the exhaust outlet. Therefore, it is necessary to set up an air supply port in the kitchen to guide the outdoor fresh air to the kitchen, so that the air circulation is formed and exhausted outside through the range hood. [0003] However, in cold weather, when the range hood does not need to work due to the temperature difference between indoor and outdoor, the cold air outside will enter the room due to the temperature difference between the indoor and outdoor, thereby causing heat loss in the house and affecting people's daily life. Especially in the cold regions of the north, it is particularly affected by this, which does not meet the requirements of emerging energy-saving houses for indoor heat loss. Contents of the...
