Description

Technical Field

[0001] This utility model relates to the field of wall-hung boiler technology, and in particular to a high-efficiency, noise-reducing gas wall-hung boiler. Background Technology

[0002] When a wall-hung boiler is in use, a fan draws in air and gas, mixes them, and then sends the mixture to the burner for combustion. During the air intake process, due to the pressure difference between the air and gas and the pipework, significant noise is easily generated, severely impacting the user experience. Existing technologies have incorporated numerous noise reduction devices, such as those at the air inlet of the casing or the fan inlet, but these generally suffer from poor noise reduction and are excessively large. Therefore, existing technologies cannot meet our needs. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a high-efficiency noise-reducing gas wall-hung boiler that can reduce noise.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A high-efficiency, noise-reducing gas wall-hung boiler includes:

[0006] The outer casing has an installation cavity, in which a main heat exchanger is installed. The air inlet of the main heat exchanger is connected to a fan capable of drawing in air. The first air inlet of the fan is connected to a silencer pipe. The silencer pipe includes a first channel capable of air intake and a second channel adjacent to the first air inlet. A silencer cavity is provided between the first channel and the second channel. The diameter of the silencer cavity is larger than that of the first channel and the second channel, and a first sound-absorbing cotton is provided inside the silencer cavity.

[0007] The first sound-absorbing cotton is cylindrical in shape so that it forms a ventilation channel when installed in place.

[0008] The silencer pipe also has a second air inlet, which is located on one side of the first channel. The diameter of the first channel gradually increases from the second air inlet to the second air inlet, so that the second air inlet is funnel-shaped.

[0009] The first channel and the inner wall adjacent to the silencing cavity are provided with multiple air guide plates. The air guide plates are arranged in an arc shape and are spaced apart from each other.

[0010] The silencer pipe also has a third air inlet, which is located on the side of the second channel adjacent to the first air inlet, and the diameter of the second channel gradually increases from the third air inlet.

[0011] The silencer pipe is also provided with a connecting groove that can be fitted onto the fan. One end of the connecting groove is connected to the third air inlet, and the silencer pipe is also fitted with a fixing component that can connect and fix the silencer pipe to the fan.

[0012] The silencer tube includes a first tube body and a second tube body that are detachably connected. When the first tube body and the second tube body are connected to each other, they form the first channel, the second channel, and the silencer cavity. The first tube body is provided with a protruding connecting protrusion, and the second tube body is provided with a connecting slot into which the connecting protrusion can be engaged.

[0013] The outer wall of the first tube is provided with multiple locking blocks, and the outer wall of the second tube is provided with multiple buckles that can be engaged by the locking blocks.

[0014] The outer casing includes a base frame, and side plate frames are provided on both sides of the base frame. A second sound-absorbing cotton plate is provided on the side plate frames.

[0015] The outer casing also includes a top plate connected to the base frame, and the top plate is provided with a flue pipe seat, which is connected to the air outlet of the main heat exchanger.

[0016] Compared with existing technologies, this utility model has the following advantages: The first air inlet of the fan is connected to a silencer pipe, the inner diameter of which is arranged in a "small-large-small" pattern, that is, the first channel, the silencer cavity, and the second channel are arranged in sequence, and the diameter of the silencer cavity is larger than that of the first and second channels. When air flows through the silencer pipe, the airflow speed slows down after entering the silencer cavity due to the sudden expansion of the space, and the sound in the airflow is reduced. At the same time, the first sound-absorbing cotton set in the silencer cavity further absorbs and blocks sound waves, which greatly reduces the noise of the airflow entering the fan, thereby effectively reducing the noise generated by the gas wall-hung boiler during operation. Users will not be disturbed by a lot of noise when using the gas wall-hung boiler, improving the comfort during use. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] like Figures 1 to 7 As shown, a high-efficiency noise-reducing gas wall-hung boiler includes: a shell 1, wherein the shell 1 is provided with an installation cavity 11, wherein a main heat exchanger 2 is provided in the installation cavity 11, wherein an air inlet of the main heat exchanger 2 is connected to an air-drawing fan 3, wherein a first air inlet 31 of the fan 3 is connected to a silencer pipe 4, wherein the silencer pipe 4 includes a first air-drawing channel 41 and a second channel 42 adjacent to the first air inlet 31, wherein a silencer cavity 43 is provided between the first channel 41 and the second channel 42, wherein the diameter of the silencer cavity 43 is larger than that of the first channel 41 and the second channel 42, and wherein a first sound-absorbing cotton 44 is provided in the silencer cavity 43.

[0027] The first air inlet 31 of the fan is connected to a silencer pipe 4. The inner diameter of the silencer pipe 4 is arranged in a "small-large-small" pattern, that is, the first channel 41, the silencer cavity 43, and the second channel 42 are arranged in sequence, and the diameter of the silencer cavity 43 is larger than that of the first channel 41 and the second channel 42. When air flows through the silencer pipe 4, the airflow speed will slow down after entering the silencer cavity 43 due to the sudden expansion of the space, and the sound in the airflow will be reduced. At the same time, the first sound-absorbing cotton 44 installed in the silencer cavity 43 further absorbs and blocks sound waves, which greatly reduces the noise of the airflow entering the fan 3, thereby effectively reducing the noise generated by the gas wall-hung boiler during operation. Users will not be disturbed by a lot of noise when using the gas wall-hung boiler, improving the comfort during use.

[0028] The first sound-absorbing cotton 44 is cylindrical, so that when the first sound-absorbing cotton 44 is installed, it forms a ventilation channel 441. The ventilation channel 441 ensures smooth airflow within the sound-absorbing cavity 43, effectively reducing noise. The cylindrical first sound-absorbing cotton 44 can better fit the inner wall of the sound-absorbing cavity 43, making full use of the space of the sound-absorbing cavity 43 and avoiding wasted space, thus making the overall structure of the sound-absorbing pipe 4 more compact.

[0029] In one embodiment, the first sound-absorbing cotton 44 is integrally formed; in another embodiment, a long strip of the first sound-absorbing cotton 44 is bent and rolled into a cylindrical shape.

[0030] The silencer pipe 4 also has a second air inlet 45, which is located on one side of the first channel 41. The diameter of the first channel 41 gradually increases from the second air inlet 45 to make the second air inlet 45 funnel-shaped. The funnel-shaped second air inlet 45 can more effectively guide outside air into the first channel 41, making the air intake smoother.

[0031] Multiple air guide plates 411 are provided on the inner wall of the first channel 41 adjacent to the silencing cavity 43. The air guide plates 411 are arc-shaped and spaced apart from each other. The arc-shaped air guide plates 411 can effectively guide the airflow from the first channel 41 to the silencing cavity 43 smoothly, reducing turbulence and impact when the airflow enters the silencing cavity 43, making the airflow enter the silencing cavity 43 more evenly, avoiding excessive local airflow concentration, and reducing noise.

[0032] The silencer pipe 4 also has a third air outlet 46, which is located on the side of the second channel 42 adjacent to the first air inlet 31. The diameter of the second channel 42 gradually increases from the third air outlet 46. The horn-shaped third air outlet 46 can more effectively guide the airflow from the second channel 42 to the first air inlet 31 of the fan 3. As the diameter gradually increases, the resistance to the airflow decreases, and the discharge is smoother.

[0033] The silencer pipe 4 is also provided with a connecting groove 47 that can be fitted onto the fan 3. One end of the connecting groove 47 is connected to the third air outlet 46, and the silencer pipe 4 is also fitted with a fixing member 5 that allows the silencer pipe 4 to be connected and fixed to the fan 3. The setting of the fixing member 5 ensures that the connection between the silencer pipe 4 and the fan 3 is firm and reliable, avoiding loosening or falling off due to vibration or airflow impact. The design of the connecting groove 47 makes the connection between the silencer pipe 4 and the fan 3 more precise.

[0034] The silencer pipe 4 includes a first pipe body 48 and a second pipe body 49 that are detachably connected. When the first pipe body 48 and the second pipe body 49 are connected to each other, they form the first channel 41, the second channel 42, and the silencer cavity 43. The first pipe body 48 is provided with a protruding connecting protrusion 481, and the second pipe body 49 is provided with a connecting groove 491 into which the connecting protrusion 481 can be engaged. The detachable design of the first pipe body 48 and the second pipe body 49 makes maintenance and replacement more convenient and quick. Users or maintenance personnel can easily separate the first pipe body 48 and the second pipe body 49 to inspect, clean, or replace internal components such as the sound-absorbing cotton 44 and the air guide plate 411. The engaging design of the connecting protrusion 481 and the connecting groove 491 ensures that the connection between the first pipe body 48 and the second pipe body 49 is firm and reliable, avoiding loosening or detachment due to vibration or airflow impact, and improving the structural stability of the entire silencer pipe 4.

[0035] The outer wall surface of the first tube 48 is provided with multiple locking blocks 482, and the outer wall surface of the second tube 49 is provided with multiple snap fasteners 492 that can be engaged with the locking blocks 482. The engaging design of the locking blocks 482 and the snap fasteners 492 makes the connection between the first tube 48 and the second tube 49 more secure and reliable, and the connection is also faster.

[0036] The outer casing 1 includes a base frame 12, with side panel frames 13 on both sides of the base frame 12. Second sound-absorbing cotton panels 14 are mounted on the side panel frames 13. The second sound-absorbing cotton panels 14 further absorb and block the noise generated during the operation of the gas-fired wall-hung boiler, providing noise reduction from the side of the outer casing 1. In conjunction with the silencer pipe 4, this design fully utilizes the side space of the outer casing 1 without adding excessive space, making the overall structure of the gas-fired wall-hung boiler more compact.

[0037] The outer casing 1 also includes a top plate 15 connected to the base frame 12. The top plate 15 is provided with a flue pipe seat 16, which is connected to the air outlet of the main heat exchanger 2.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
