A noise-proof integrated stove

Abstract

The invention relates to the technical field of integrated stoves, and aims to provide a noise reduction mechanism for an integrated stove, wherein the noise reduction mechanism for the integrated stove can reduce noise pollution effectively. According to the adopted technical scheme, the noise reduction mechanism for the integrated stove comprises a mounting plate and a plurality of noise reduction units which are arranged on the mounting plate; the mounting plate is matched with a smoke inlet, and a plurality of mounting holes are formed in the mounting plate corresponding to the noise reduction units in number; the noise reduction units are arranged in the mounting holes and comprise columnar shells, wherein the front ends of the shells are closed, and the rear ends of the shells are opened; resonance tubes are arranged in the shells, and resonance cavities are constituted in the resonance tubes; the front ends of the resonance tubes communicate with the rear ends of connecting pipes, and the front ends of the connecting pipes extend to the front end faces of the shells and communicate with the outside; and airflow holes communicating with inner cavities of the shells are formedin the resonance tubes. Airflow noise of the smoke inlet of the integrated stove can be effectively reduced, and the kitchen environment is improved.

Description

technical field [0001] The invention relates to the technical field of integrated stoves, in particular to a noise-proof integrated stove. Background technique [0002] Integrated stove, also known as environmental protection stove or integrated environmental protection stove in the industry, integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the effect of saving space and extracting oil fume Good, energy saving, low consumption and environmental protection. [0003] The integrated stove smoke exhaust system generally includes a hollow smoke collection hood arranged on the rear side of the top of the integrated stove main body. The front surface of the smoke collection hood is provided with a smoke inlet. . During the working process of the integrated stove, its smoke exhaust system is a major part of the noise. When the airflow enters the smoke collection hood from th...

AI Technical Summary

Problems solved by technology

However, there are defects in the above two methods: in the first method, the holes on the stencil are too large, and the effect of improving the noise spectrum is poor, resulting in unsatisfactory noise reduction effect

If the hole is too small, it will affect the smoking effect of the smoke exhaust system

In the second way, because the collected sound feedback information contains other complex multiple noises besides the noise, the speaker cannot emit the corresponding sound waves stably and accurately, which also affects the noise reduction effect.
