That is, the inlet and the outlet of the first noise reduction cavity 178 are the same structure, and the sound wave is transmitted into the resonance cavity 182 through the first pipe 180 and then transmitted out through the first pipe 180.

Through reasonable arrangement of the matching structures of the first pipeline 180 and the resonance chamber 182, the flow cross-sectional area of the first pipeline 180 is smaller than that of the resonance chamber 182, that is, the first pipeline 180 and the resonance chamber 182 are jointly constructed into a resonance cavity structure, when sound waves are transmitted to the resonance chamber 182, the part of the sound waves close to the natural frequency of the resonance cavity structure causes resonance of the resonance cavity structure, in the vibration process, the sound waves in the resonance cavity structure rub against the inner walls of the first pipeline 180 and the resonance chamber 182, mechanical energy is converted into heat energy, and therefore sound energy is consumed, and the effects of sound absorption and noise reduction can be effectively achieved.

Further, as shown in fig. 25, the plurality of noise reduction cavities includes a second noise reduction cavity 184, and the second noise reduction cavity 184 is a wave tube, and the wave tube communicates with the first communicating portion 176.

Wherein, through the structure that rationally sets up a plurality of chambeies of making an uproar for a plurality of chambeies of making an uproar include that the second makes an uproar the chamber 184 of making an uproar, and wherein, the chamber 184 of making an uproar is the wavelength pipe for the second, and makes wavelength pipe and first intercommunication portion 176 intercommunication. The size of the wave tube has a correlation with the target noise reduction frequency of the food processor 100. When the food processor 100 operates, the sound waves in the second air duct 174 are transmitted into the wavelength tube through the first communicating portion 176 and then transmitted out through the first communicating portion 176. That is, the wavelength tube has only one opening, and the sound wave is transmitted into the wavelength tube from the first communicating portion 176, a part of the sound wave is absorbed, and a part of the sound wave is transmitted from the same first communicating portion 176.

When the food processer 100 works, the noise frequency characteristic is kept unchanged, and the size of the wave pipe has relevance to the target noise reduction frequency of the food processer 100, so that the purpose of eliminating the noise corresponding to the target noise reduction frequency can be achieved. Through setting up the wavelength pipe that frequency corresponds with the target noise reduction, can have corresponding ground to reduce cooking machine 100's operation noise, and noise reduction effect is good.

Specifically, the sound wave is transmitted into the wave tube through the first communicating portion 176, reaches the bottom of the wave tube, and is reflected, the reflected wave and the incident wave are superposed to form a standing wave, the node of the standing wave is located at the bottom of the wave tube, and when the antinode of the standing wave is located at the first communicating portion 176, resonance occurs, at which the particle amplitude is the largest, and the consumed sound energy is also the largest, so that a significant sound absorption effect is achieved at the resonance frequency.

Specifically, the plurality of noise reduction cavities includes at least one first noise reduction cavity 178 and at least one second noise reduction cavity 184; or the plurality of noise reduction cavities includes a plurality of first noise reduction cavities 178; alternatively, the plurality of noise reduction cavities may include a plurality of second noise reduction cavities 184, with one second noise reduction cavity 184 being used to remove a band of noise and one first noise reduction cavity 178 being used to remove a band of frequency noise. That is, the number of the first noise reduction cavity 178 and the second noise reduction cavity 184 can be set according to the actual use requirement, so as to achieve the purpose of noise of the target frequency.

For example, the broadband sound absorption is realized by utilizing the matching relationship between the first noise reduction cavities 178 with different specifications and the second noise reduction cavities 184 with different specifications.

Specifically, the first noise reduction cavity 178 includes a first pipe 180 and a resonance cavity 182, and the target noise reduction frequency is determined according to the volume size of the resonance cavity 182, the length of the first pipe 180 and the flow cross-sectional area of the first pipe 180. The first noise reduction cavity 178 belongs to a narrow band muffler. The muffling frequency of the second chamber 184 (i.e., the wavelength tube) is related to the length of the wavelength tube, and the longer the wavelength tube is, the lower the muffling frequency is, so that the first chamber 178 and the second chamber 184 cooperate with each other to increase the muffling bandwidth and reduce the noise in a wide frequency range.

Further, the sound velocity c2, the length L2 of the wavelength tube, and the target noise reduction frequency f2 of the food processor 100 satisfy:

when the food processor 100 is in operation, the target noise reduction frequency characteristic is kept unchanged, and the sound velocity c2, the length L2 of the wavelength tube and the target noise reduction frequency f2 of the food processor 100 satisfy the following conditions:

that is, the sound velocity c2 and the length L2 of the wave tube have a relationship with the target noise reduction frequency f2 of the food processor 100. The length of the wavelength tube is inversely related to the target noise reduction frequency. The longer the length of the wave length tube is, the lower the target noise reduction frequency is; the shorter the length of the wave length tube, the higher the target noise reduction frequency.

Specifically, the flow cross-sectional area of the waveguide tube is positively correlated with the amount of noise reduction. The larger the flow cross-sectional area of the wave tube is, the larger the noise elimination quantity is; the smaller the flow cross-sectional area of the wave tube is, the smaller the noise elimination amount is.

Furthermore, the target noise reduction frequencies corresponding to any two noise reduction cavities in the plurality of noise reduction cavities are different. Therefore, the noise reduction treatment can be carried out on the noise corresponding to the target noise reduction frequencies by utilizing the plurality of noise reduction cavities, and effective and reliable structural support is provided for realizing broadband sound absorption.

Specifically, the target noise reduction frequencies corresponding to any two of the plurality of noise reduction cavities are different, and the size of the noise reduction cavity is related to the target noise reduction frequency, so that the size of any two of the plurality of noise reduction cavities can be understood as different.
