[0036] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0037] The utility model provides a combustion chamber system for preventing power attenuation, which includes: a water heater shell 10, a top of which is provided with an air outlet 110; a combustion assembly 20, which is arranged in the water heater shell 10; the combustion assembly 20 includes a combustion component 210, a heat exchange component 220 and a smoke hood 230; an air inlet channel 30 is formed between the combustion assembly 20 and the water heater shell 10, and the air inlet channel 30 is connected to the air outlet 110; the combustion assembly 20 is provided with an air inlet 211 and an air outlet 231110, and the air inlet 211 is connected to the air inlet channel 30; a smoke exhaust component 40, which is arranged in the water heater shell 10 and is connected to the air outlet 231110.

[0038] Specifically, the smoke exhaust assembly 40 is powered and generates suction, so that the air outside the water heater shell 10 enters the water heater shell 10 through the air port 110, and then enters the air inlet channel 30 and moves downward under the action of the smoke exhaust assembly 40. The air finally enters the combustion assembly 210 through the air inlet 211 at the bottom of the combustion assembly 20, mixes with the gas in the combustion assembly 210 and burns, heating the water in the heat exchange assembly 220. The smoke generated during the combustion process will enter the smoke hood 230 and be discharged outside the water heater shell 10 through the air outlet 231110 and the smoke exhaust assembly 40. The heat generated during the combustion process of the combustion assembly 210 will be transferred to the air inlet channel 30 by heat transfer, preheating the air in the air inlet channel 30 to improve the combustion efficiency, thereby preventing power attenuation, saving energy and reducing emissions.

[0039] Compared with the prior art, in the present application, under the action of the smoke exhaust component 40, the air outside the water heater shell 10 enters the water heater shell 10 through the air port 110, and the air flows to the air port 211 below the combustion assembly 20 through the air inlet channel 30, and finally mixes with the gas in the combustion component 210 to burn and release heat, thereby heating the water in the heat exchange component 220; wherein, the air inlet channel 30 is arranged between the combustion assembly 20 and the water heater shell 10, and can use the heat emitted by the combustion assembly 20 to preheat the air in the air inlet channel 30, so as to solve the problem of power attenuation encountered by the combustion chamber system during use, so that the attenuation rate is reduced to less than 1%, thereby greatly improving the service life and quality of use of the product.

[0040] In one embodiment, the water heater housing 10 includes a back plate 101. In this embodiment, the air inlet channel 30 is arranged between the combustion assembly 20 and the back plate 101 so as to reasonably utilize the space in the water heater housing 10, thereby avoiding the layout design of the air inlet channel 30 affecting the installation of other components and avoiding obstruction of work when repairing and replacing other components.

[0041] In one embodiment, the air inlet duct 30 includes a first air inlet section 310 and a second air inlet section 320. The first air inlet section 310 is provided corresponding to the smoke hood 230, and the second air inlet section 320 is provided corresponding to the combustion assembly 210. Through the above-described arrangement, this embodiment can gradually preheat the air in the air inlet duct 30 by utilizing the smoke hood 230 and the combustion assembly 210, thereby rationally utilizing the heat emitted by the smoke hood 230 and the combustion assembly 210.

[0042] Furthermore, the smoke hood 230 includes a hood body 232 and two hood side panels 233, the two hood side panels 233 being respectively disposed on the left and right sides of the hood body 232. A first mounting portion 234 is provided on the rear side of each of the hood side panels 233. The first mounting portion 234 is mounted and connected to the water heater housing 10, so that a first air inlet section 310 is formed between the hood body 232 and the water heater housing 10. Taking the combustion assembly 20 mounted to the back plate 101 as an example, this embodiment, by mounting the first mounting portion 234 to the back plate 101, not only secures the smoke hood 230 but also enables the smoke hood 230 to be raised by means of the first mounting portion 234, thereby forming the first air inlet section 310 between the hood body 232 and the water heater housing 10.

[0043] Furthermore, the combustion assembly 210 includes a combustion chamber 212 and a burner 213 disposed within the combustion chamber 212; the combustion chamber 212 is connected to the smoke hood 230; and the heat exchange assembly 220 is disposed between the combustion chamber 212 and the smoke hood 230. In this embodiment, by connecting the combustion chamber 212 to the smoke hood 230, the combustion assembly 210, the heat exchange assembly 220, and the smoke hood 230 are combined into a single unit, namely, the combustion assembly 20, for ease of installation.

[0044] Furthermore, the combustion chamber 212 includes a combustion chamber back plate 2121, a combustion chamber cover plate 2122 and two combustion chamber side plates 2123, and the two combustion chamber side plates 2123 are respectively arranged on the left and right sides of the combustion chamber back plate 2121, and the combustion chamber cover plate 2122 is arranged corresponding to the combustion chamber back plate 2121 and is connected to the smoke hood 230; the rear sides of the two combustion chamber side plates 2123 are provided with a second mounting portion 2124, and the second mounting portion 2124 is installed and connected to the water heater shell 10 to form the second air inlet section 320 between the combustion chamber back plate 2121 and the water heater shell 10. Taking the installation of the combustion assembly 20 to the back plate 101 as an example, this embodiment installs the second mounting portion 2124 to the back plate 101, thereby not only achieving the installation and fixation of the combustion chamber 212, but also enabling the combustion chamber 212 to be lifted with the help of the second mounting portion 2124, so that the second air inlet section 320 is formed between the combustion chamber back plate 2121 and the water heater shell 10.

[0045] Furthermore, the air inlet 211 is provided at the bottom of the combustion chamber 212 , so that the air in the air inlet channel 30 enters the combustion chamber 212 through the air inlet 211 at the bottom of the combustion chamber 212 .

[0046] In one embodiment, the smoke exhaust assembly 40 is provided with a smoke exhaust pipe 410, and the smoke exhaust pipe 410 extends from the air outlet 110 to the outside of the water heater shell 10. The smoke exhaust pipe 410 of this embodiment is arranged in the air outlet 110 and extends from the air outlet 110 to the outside of the water heater shell 10, and the space layout is rationally utilized by sharing the air outlet 110.

[0047] Furthermore, the exhaust pipe 410 is coaxially arranged with the air outlet 110 , and an air inlet area is reserved between the exhaust pipe 410 and the air outlet 110 so that air outside the water heater housing 10 enters the water heater housing 10 from the air inlet area.
