Integrated cooker with active noise reduction function

Abstract

The invention provides an integrated cooker with an active noise reduction function. The integrated cooker comprises an integrated cooker main body, a controller, a sound acquisition device and a loudspeaker, wherein the integrated cooker main body comprises a gas cooking bench and an air inlet cavity formed in the gas cooking bench, a negative pressure cavity is formed below the air inlet cavity,the air inlet cavity is communicated with the negative pressure cavity through a smoke exhaust pipeline, a centrifugal fan system is arranged in the negative pressure cavity, oil fume generated at the gas cooking bench enters the smoke exhaust pipeline through the air inlet cavity, passes through the centrifugal fan system and is exhausted outdoors through an external flue channel, the loudspeaker is in communication connection with the controller, the sound acquisition device is in communication connection with the controller, is mounted on the integrated cooker main body and is used for collecting sound waves on the outer side of the integrated cooker main body and sending the sound waves to the controller, and the controller is used for determining a target sound wave according to thesound wave and controlling the loudspeaker to sound according to the target sound wave. By adopting the integrated cooker, the noise of the integrated cooker during working is effectively reduced, anda quieter and more comfortable living environment is brought to users.

Description

technical field [0001] The invention relates to the technical field of integrated stoves, in particular to an integrated stove with an active noise reduction function. Background technique [0002] Noise is a serious source of pollution, which has a great impact on people's daily work and life. With the improvement of living standards, people's tolerance for noise is getting smaller and smaller. It is urgent to reduce noise in daily life and work. . [0003] At present, the integrated stove is a kitchen appliance that integrates the two main functions of the range hood and the gas stove. It has the advantages of energy saving, environmental protection, and high oil absorption rate. However, when the integrated stove is working, the fan will generate noise. , Passive noise reduction methods such as adding sound-absorbing cotton cannot effectively reduce low-frequency noise, but they cannot achieve a good balance between performance improvement and noise reduction, and the no...

[0003] At present, the integrated stove is a kitchen appliance that integrates the two main functions of the range hood and the gas stove. It has the advantages of energy saving, environmental protection, and high oil absorption rate. However, when the integrated stove is working, the fan will generate noise. , adding passive noise reduction methods such as sound-absorbing cotton cannot effectively reduce low-frequency noise, but it cannot achieve a good balance between performance improvement and noise reduction, and the noise reduction effect is poor
