Example Embodiment
[0029] Example 1
[0030] This embodiment provides a noise reduction structure, such as figure 1 and figure 2 As shown, it includes a sound channel 1 and a sound-absorbing layer 2; both ends of the sound channel 1 are open, and both ends can extend outwards, so as to adjust the length of the sound channel 1 according to the wavelength of the noise. The sound-absorbing layer 2 is arranged in the sound channel 1 and is at least one layer.
[0031] In this way, both ends of the sound channel 1 are open, and the noise enters from both ends of the sound channel 1, resulting in a standing wave effect and resonance noise reduction, that is, the sound channel 1 forms a resonant standing wave structure, thereby achieving noise reduction;
[0032] At the same time, both ends of the sound channel 1 can extend outward, that is, the length of the sound channel 1 can be adjusted, and can be adjusted according to the wavelength of the noise. The noise entering at both ends of channel 1 p...
Example Embodiment
[0058] Example 2
[0059] This embodiment provides a gas water heater, such as Figure 5 and Image 6 As shown, the gas water heater includes the noise reduction structure of Embodiment 1, a water heater main body 5, a fan assembly 6 and a control assembly 7, the fan assembly 6 is arranged in the water heater main body 5, the sound channel 1 and the drive The component 4 is arranged on the water heater main body 5, and the control component 7 is electrically connected with the fan component 6 and the driving component 4, at least for obtaining the maximum noise wavelength according to the rotational speed of the fan component 6, and passing the The driving component 4 adjusts the length of the sound channel 1 to be 1 / 4 of the maximum noise wavelength.
[0060] Specifically, the fan assembly 6 is arranged in the water heater main body 5, the control assembly 7 is arranged on the water heater main body 5, the extension body 12 in the sound channel 1 is connected to the water h...
