Embodiment 1

[0036] Embodiment 1: In this embodiment 1, a device for detecting the concentration of oil fume from a range hood, such as figure 1 As shown, comprise: audio processing module 2, comprise audio collection unit 21 and audio processing unit 22, the sound that audio collection unit produces when being used for collecting cooking and is converted into audio signal, and audio processing unit is used for the output of audio collection unit The audio signal is intelligently processed to form a signal of the amount of oil fume;

[0037] The range hood control module 3 is connected to the audio processing module and receives the signal of the amount of oil fume, and compares it with the built-in oil fume reference signal to form a fan control signal and output it to the fan drive module for driving the fan 11;

[0038] The fan drive module 4 is used to receive the fan control signal and drive and adjust the fan on the range hood;

[0039] The button and indication module 5 is connected ...

Embodiment 2

[0054] Embodiment 2: A device for detecting the concentration of oil fume in a range hood according to Embodiment 2, including an audio processing module, a range hood control module, a fan drive module, buttons and an indication module, the audio processing module is installed on the range hood, and the audio processing module The output signal of the amount of cooking fume is transmitted to the control module of the range hood by wire. The other parts of the second embodiment are similar to the corresponding parts of the first embodiment, and will not be repeated here.

Abstract

The invention discloses a device and a method for detecting the oil smoke concentration of a range hood. The device comprises an audio processing module, a range hood control module, a fan driving module and a button and instruction module, wherein the audio processing module comprises an audio acquisition unit and an audio processing unit. According to the device and the method, a cooking sound is acquired and is taken as the basis of oil smoke concentration after being processed by the audio processing module; the processed cooking sound is compared with a reference oil smoke signal in the range hook control module to judge the oil smoke concentration, the rotating speed of a fan can be further controlled, the air suction amount of the range hood is adjusted, and the air amount of the range hood can be automatically controlled; as being not arranged in an oil smoke suction and exhaust channel, a detection element does not be easily wrapped by oil stains to have failure, and thus the device and the method are high in detection accuracy and reliability.

Description

technical field [0001] The invention relates to a range hood, in particular to a device and a detection method for detecting the concentration of the range hood capable of judging the concentration of the range hood with high accuracy and reliability by collecting sounds during the cooking process. Background technique [0002] With the advancement of current technology, the degree of intelligence of home appliances is getting higher and higher, and it has gradually evolved from manual control to automatic control. For range hoods, there is an urgent need for a reliable and effective method to detect the concentration of lampblack. In order to realize the automatic control of the air volume, there are several methods for detecting the concentration of oil fume in the range hood. For example, the Chinese invention patent with the application number of 200810028649.9 discloses a method of placing a light source emitting device and a photoelectric conversion device at the oil fu...
