Air amount adjusting device and method of extractor hood

Abstract

The invention relates to an air amount adjusting device of an extractor hood and a control method of the air amount adjusting device of the extractor hood. The air amount adjusting device comprises a main control unit of the extractor hood, and a fan motor connected with the main control unit of the extractor hood and used for driving a fan to work. The air amount adjusting device is characterized by also comprising a temperature sensor for detecting the temperature of the bottom of a pot arranged on a gas stove, a pot bottom temperature detection circuit connected with the temperature sensor, a main control unit of the gas stove, a wireless signal transmitting module connected with the main control unit of the gas stove, and a wireless signal receiving module connected with the main control unit of the extractor hood, wherein the main control unit of the gas stove is connected with the pot bottom temperature detection circuit. The main control unit of the gas stove can be used for calculating smoke amounts according to the pot bottom temperature detected by the pot bottom temperature detection circuit; then the main control unit of the gas stove transmits smoke amount information to the wireless signal receiving module through the wireless signal transmitting module; the wireless signal receiving module then transmits the smoke amount information to the main control unit of the extractor hood; and the main control unit of the extractor hood controls the fan motor to work at different rotating speeds according to the smoke amounts.

Description

technical field [0001] The invention relates to a device and method for adjusting the air volume of a range hood. Background technique [0002] The range hood is one of the indispensable electrical appliances in the home kitchen, and it is mainly used to suck the oil fume produced during cooking. The Chinese patent application number 200510048587.4 discloses a system for controlling the range hood by detecting the gas concentration. When the gas concentration exceeds a certain value, the system turns on the range hood. However, when the gas combustion is relatively sufficient, the gas concentration in the kitchen is very low. , the system will not work properly. [0003] The main function of the range hood is to ventilate, that is, to draw the air containing oil fume in the kitchen into the smoke pipe, and discharge it through the flue, so as to achieve the purpose of exhausting oil fume and improving the air. The exhaust air volume of the existing range hoods is realized ...

Problems solved by technology

In this solution, it is necessary to set up a complex smoke detection unit and smoke volume analysis unit, and the camera collects the image of the range hood stove in the kitchen, and the range hood stove is mostly uneven, and during the cooking process, the ingredients will change. Constant flipping, so the background after shooting is more complicated, which is not conducive to the analysis and judgment of the subsequent smoke detection unit and subsequent smoke volume analysis unit, the cost is high, and the judgment is not accurate
