Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-3, an integrated cooker with noise reduction function includes an integrated cooker body 1, a burner 2 disposed on a cooking bench of the integrated cooker body 1, a smoke exhaust ventilator 3 disposed on a rear side of the cooking bench of the integrated cooker body 1, and a smoke exhaust ventilator 4 disposed on an inner side surface of the integrated cooker body 1, wherein an air inlet of the smoke exhaust ventilator 4 is connected to a smoke exhaust duct of the smoke exhaust ventilator 3, an air outlet of the smoke exhaust ventilator 4 is connected to an external smoke exhaust duct, the smoke exhaust ventilator 3 is provided with a microphone 5, a signal processing module 7 and a speaker 6, and the microphone 5 and the speaker 6 are electrically connected to the signal processing module 7.

In order to reduce noise better, the fume extractor 4 is electrically connected to the signal processing module 7. The signal processing module 7 can control and reduce the running speed of the smoke exhaust ventilator 4 according to the actual situation, so that the noise can be reduced better.

In order to make the processing of the noise more fit to the human body, the cigarette machine head 3 comprises a smoke baffle 301 at the lower part, a smoking mouth part 302 positioned above the smoke baffle 301 and a cigarette head cover 303 positioned above the smoking mouth part 302, and the signal processing module 7, the microphone 5 and the loudspeaker 6 are arranged on the cigarette head cover 303. The position is reasonable in layout, the head of the operator is close, the noise processing is more in accordance with the feeling of the human body, and the effect is better.

In order to better detect the noise, the microphone 5 is located inside the hood 303 and the head of the microphone 5 is exposed downward and opposite to the burner 2. The position orientation can better detect the noise generated by the flame inside the integrated stove body 1 and the burner 2.

For a better sound deadening feeling of the operator, the sound emitting hole of the speaker 6 is located on the front side of the hood 303. The sound outlet hole is closest to the head of an operator, and the silencing effect is good.

In order to achieve sound wave interference corresponding to the noise frequency, the speaker 6 employs a low frequency horn. Because the flame of the fume exhaust fan 4 and the burner 2 basically generates low-frequency noise of 100 plus 1000 Hz, the low-frequency horn has strong pertinence, can well realize sound wave interference and has good silencing effect.

To facilitate noise detection and achieve a better muffling effect, the mouthpiece portion 302 is tilted forward from bottom to top. Smoking effect is good to make cigarette end cover 303 more nearly from people's head, more be close directly over furnace end 2, the noise of being convenient for is surveyed, and noise cancelling effect is better.

In order to achieve targeted detection and sound attenuation, the positions and the number of the microphones 5 and the loudspeakers 6 correspond to the positions and the number of the burner 2, and the switching circuit 8 of the burner 2 is electrically connected with the signal processing module 7. The signal processing module 7 can realize the targeted detection and the sound attenuation according to the use condition of the actual furnace end 2.

During operation, signal processing module 7 is according to the actual use condition of furnace end 2, and the noise that smoke exhaust ventilator 4 and stove fire produced is listened to corresponding microphone 5 of control, and signal transmission to signal processing module 7, signal processing module 7 judges the back according to the signal of gathering, produce through speaker 6 with noise opposite phase place, the same sound wave of amplitude offsets the noise, simultaneously, according to actual conditions, the steerable 4 operating speeds that reduce smoke exhaust ventilator of signal processing module 7 can reduce the noise better, effectively realize wholly falling the noise.

The integrated cooker with noise reduction function shown in fig. 1-3 is a specific embodiment of the present invention, which embodies the substantial features and advantages of the present invention, and can be modified in the same way as the present invention in the aspects of shape and structure according to the practical needs of use, all within the scope of protection of the present solution.
