Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. The utility model provides an each technical feature can the interactive combination under the prerequisite of conflict each other.

With reference to fig. 1 and 2, this is an embodiment of the invention, in particular:

the utility model provides a structure of making an uproar falls, is including being first sound-proof wall 100 and the second sound-proof wall 200 that the interval set up around being be equipped with the pad frame 300 of annular frame structure between first sound-proof wall 100 and the second sound-proof wall 200, first sound-proof wall 100, second sound-proof wall 200 and pad frame 300 form inclosed air chamber 400 be equipped with first sound absorbing layer 110 on the wall of first sound-proof wall 100 be equipped with second sound absorbing layer 210 on the wall of second sound-proof wall 200, first sound absorbing layer 110, second sound absorbing layer 210 are the sound cotton of inhaling, first sound-proof wall 100 all adopts rigid plastic to make with second sound-proof wall 200. When the noise passes through the noise reduction structure from back to front, part of the noise is absorbed by the second sound absorption layer 210 to be weakened, when the rest of the noise passes through the air cavity 400, due to the change of the transmission medium, the noise can collide back and forth between the first sound insulation wall 100 and the second sound insulation wall 200, the sound wave energy is converted into mechanical energy and heat energy, the noise is weakened again, the weakened noise is continuously absorbed when passing through the first sound absorption layer 110, and then the sound absorption and sound insulation effects are realized, the coincidence effect refers to the phenomenon that the sound insulation quantity is reduced because the sound wave action caused by the incident angle of the sound wave is matched with the transmission speed of the bending wave in the partition walls, the first sound insulation wall 100 and the second sound insulation wall 200 made of rigid plastics are not easy to generate bending vibration, namely the sound insulation walls are not easy to generate the bending wave, and further are not easy to generate the coincidence effect, the sound insulation performance is improved, the rigid plastics are ABS or PS or PC or, the sound insulation wall is made of light, thin and flexible materials, because the materials easily cause the anastomosis effect, under the excitation of sound waves, the inherent free bending wave propagation speed of the materials is the same as that of the excited sound waves, a large amount of sound energy is transmitted from one side to the other side, and the sound insulation performance is greatly weakened.

Further, in a preferred embodiment, a plurality of spacers 410 are uniformly distributed in the air chamber 400, the spacers 410 are connected to the second sound-insulating wall 200 and the first sound-insulating wall 100, so that the connection between the first sound-insulating wall 100 and the second sound-insulating wall 200 can be more firm, and the spacers 410 and the cushion frame 300 are made of soft silicone rubber. The soft silicone rubber avoids the formation of acoustic bridges that would cause the air cavity 400 to fail.

In a further preferred embodiment, the first sound absorbing layer 110 is attached to the rear wall surface of the first soundproof wall 100, the second sound absorbing layer 210 is attached to the front wall surface of the second soundproof wall 200, and a heat insulating layer 220 is attached to the rear wall surface of the second soundproof wall 200, the heat insulating layer 220 being an aluminum foil, thereby preventing the high-temperature damage.

In the prior art, two adjacent sound insulation walls are arranged in a non-parallel manner, and the glass facing to the sound source side has a certain inclination angle so as to weaken the resonance effect, but the first sound insulation wall 100 and the second sound insulation wall 200 in the embodiment are parallel to each other, so that the noise keeps reflecting back and forth in the air cavity 400, the reflecting times are increased, the sound absorption effect of the first sound absorption layer 110 and the second sound absorption layer 210 is better, and the noise is prevented from being refracted between the first sound insulation wall 100 and the second sound insulation wall 200 and being transmitted from the edge of the air cavity 400.

This embodiment still provides a gas heater, and gas heater includes fall and make an uproar structure and shell 500, shell 500 is including setting up in the face lid 510 of front side, fall and make an uproar the structure and set up in the back of face lid 510, the preceding wall of first sound-proof wall 100 is hugged closely with the back of face lid 510 it installs combustion assembly 600 in the shell 500 of structure rear side to fall, combustion assembly 600 includes fan and combustor.

In the working process of the gas water heater, when the rotation noise of the fan and the combustion noise in the burner are transmitted out from the inside of the shell 500 and pass through the noise reduction structure, part of the noise is absorbed by the second sound absorption layer 210 to be reduced, when the rest of the noise passes through the air cavity 400, due to the change of the transmission medium, the noise can collide back and forth between the first sound insulation wall 100 and the second sound insulation wall 200, the sound wave energy is converted into mechanical energy and heat energy, the first sound absorption layer 110 and the second sound absorption layer 210 absorb the noise, the noise is reduced again, and the reduced noise is transmitted out only after being continuously absorbed by the first sound absorption layer 110. Break through the simple sound-proof structure of current water heater, possess simultaneously and inhale sound and syllable-dividing effect, possess good noise reduction effect, the installation of being convenient for, the cost is lower.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
