AI Technical Summary
When the existing integrated stove is working, the noise generated by the fan is spread through the oil fume channel, resulting in high noise and affecting the user experience. The prior art mainly sets a noise reduction structure in the air duct system, but ignores the noise reduction problem in the smoke collecting chamber, resulting in poor noise reduction effect.
The noise reduction structure is set up in the smoke stove module of the integrated stove, which specifically includes installing a noise reduction plate at the bottom of the cover plate and setting a noise reduction hole on the noise reduction plate. The noise reduction plate can be filled with sound-absorbing materials such as sound-absorbing cotton. The noise reduction structure is located in the negative pressure chamber, close to the fan, to reduce noise propagation.
By setting up a noise reduction structure in the negative pressure chamber, the distance between the noise reduction structure and the fan is reduced, the noise reduction effect is significantly improved, and the user experience is improved.
