Intelligent kitchen ventilation and air exchange device

Abstract

The invention relates to the technical field of intelligent kitchen regulation and control, in particular to an intelligent kitchen ventilation and air exchange device, which comprises a humidity acquisition circuit, a signal amplification circuit and a comparison control circuit which are electrically connected in sequence. The comparison control circuit comprises a first integrated operational amplifier U1. The output end of the first integrated operational amplifier is electrically connected with a humidifier; the forward input end of the first integrated operational amplifier is electrically connected with the signal amplification circuit; the reverse input end of the first integrated operational amplifier is electrically connected with the control end of a thirteenth resistor R13; thefirst end and the second end of the thirteenth resistor are electrically connected with a power supply; and a first power supply end 1 and a second power supply end 2 of the first integrated operational amplifier are electrically connected with the power supply respectively. According to the intelligent kitchen ventilation and air exchange device, by arranging the comparison control circuit, thehumidity is accurately controlled within a comfortable range suitable for work, the control precision is high, and automatic control over the humidity is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent kitchen control, in particular to an intelligent kitchen ventilation device. Background technique [0002] In the home kitchen, the range hood is usually turned on to discharge the fume and steam out of the room when cooking. In the case of low outdoor weather in the north, it is often necessary to close the doors and windows, so the room is relatively closed. In this case, gas is used to cook. When cooking, especially when using a range hood, there will often be a peculiar smell in the room. This is because the combustion of the gas itself will consume part of the oxygen, and the air pressure in the kitchen will be slightly reduced. Intensified, then, in order to maintain the balance of indoor air pressure, air compensation will inevitably occur, and the outdoor air can only enter from the only sewer that communicates with the outside world, which will increase the anti-odor of the sewer and ...
