Problems solved by technology

[0005] In view of this, the object of the present invention is to provide a noise reduction structure, by providing a sound channel with openings at both ends and the end can be extended outwards, and setting a sound attenuation layer in the sound channel, the noise can be reduced from the left and right sides of the sound channel. Entering at both ends produces a standing wave effect, resonates and eliminates noise, and at the same time, the anechoic layer absorbs sound and reduces noise, and the noise reduction effect is good, which effectively solves the noise problem generated by the existing gas water heater when it is working

Embodiment 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; the sound channel 1 has openings at both ends, and both ends can be extended outwards, which is used 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, resonance and noise elimination, that is, the sound channel 1 forms a resonant standing wave structure, thereby achieving noise reduction;

[0032] At the same time, the two ends of the sound channel 1 can be extended outward, that is, the length of the sound channel 1 can be adjusted, and can be adjusted according to the wavelength of the noise. For example, the length of the sound ch...

Embodiment 2

[0059] This embodiment provides a gas water heater, such as Figure 5 and Figure 6 As shown, the gas water heater includes the noise reduction structure of Embodiment 1, the water heater body 5, the fan assembly 6 and the control assembly 7, the fan assembly 6 is arranged in the water heater body 5, the sound channel 1 and the drive The component 4 is arranged on the water heater body 5, the control component 7 is electrically connected with the fan component 6 and the drive component 4, at least for obtaining the maximum noise wavelength according to the rotation speed of the fan component 6, and through The driving assembly 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 with the water heater main body 5, the driving assembly...

Abstract

The invention discloses a noise reduction structure and a gas water heater applying the same. The noise reduction structure comprises a sound channel and a noise elimination layer. The two ends of thesound channel are open, can extend outwards, and are used for adjusting the length of the sound channel according to the wavelength of noise. The silencing layer is arranged in the sound channel, andthe number of the silencing layer is at least one. By arranging the sound channel with the two open ends and the ends capable of extending outwards and arranging the silencing layer in the sound channel, noise can enter the sound channel from the left end and the right end of the sound channel to generate the standing wave effect, and resonance silencing is achieved; the length of the sound channel can be adjusted according to the wavelength of the noise, so that the sound absorption frequency is adjusted, and the noise reduction effect is ensured; meanwhile, the silencing layer can be simplein structure, similar to a mass spring system and good in resonance silencing, sound absorption, noise reduction and noise reduction effects, the noise problem generated when an existing gas water heater works is effectively solved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of noise reduction structures, and in particular relates to a noise reduction structure and a gas water heater using the same. Background technique [0002] Gas water heater refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through the heat exchanger through combustion heating to achieve the purpose of preparing hot water; gas water heaters are popular among consumers for their energy saving and environmental protection advantages. Granted, it's also annoyingly noisy when it's running. [0003] It is understood that the national standard requires that the noise of gas water heaters be no more than 65 decibels when they are burning, while the noise emitted by ordinary gas water heaters when they are running is generally above 55 decibels. If the noise level is too high, it will affect people's hearing. According to medical experiment data, the noise value of more than ...
