Method and control system for automatically controlling range hood through infrared temperature induction

Abstract

The invention relates to a method and a control system for automatically controlling the range hood through infrared temperature induction. According to the method, a temperature rise value of a gas stove is detected in real time; segmented circulation processing is carried out through a single chip microcomputer chip, the temperature rise value read in real time in the last section is stored, andthen the real-time temperature rise value is read in the next section and is compared with the temperature rise value read in the last section to form circulation; and the range hood is controlled tobe started, adjusted speed and closed according to the number of times when the temperature rise value reaches a program setting value within a set time period. The invention further discloses a control system for automatically controlling the range hood through the infrared temperature induction using the control method. The method and the control system for automatically controlling the range hood through the infrared temperature induction have the advantages that the processing speed is high, the adjustability is high, the cleaning is easy, the detection range is large, the power consumption is low, the stability is high, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a method for automatically controlling a range hood by infrared temperature sensing and a control system. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the healthy and energy-saving range hood stove in the kitchen. It can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. [0003] With the improvement of automation level, existing range hoods have also begun to add elements of automatic control. At present, the range hood that is automatically opened on the market is composed of a gas sensor and a processing drive circuit. It mainly relies on the gas sensor to output a signal to the pr...

Problems solved by technology

At present, the range hood that is automatically opened on the market is composed of a gas sensor and a processing drive circuit. It mainly relies on the gas sensor to output a signal to the processing drive circuit when it senses gas smoke. When there is no gas, it will be closed with a delay. In this system, the gas sensor is easy to be polluted by oil fumes, and it is difficult to clean the gas sensor (the gas sensor needs to pass the gas or smoke to the inner layer through the filter screen on the surface for induction), and the sensitivity of the outgoing line is reduced. And the service life is shortened, the automatic control function is seriously lost, and there are defects; and because there is a certain distance between the fume collecting hood of the range hood and the heater, when the amount of fume is small, the fume cannot reach in time and trigger the fume sensor , and then there is a phenomenon that the range hood does not start when the lampblack is generated
