[0021] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0023] As shown in the figure, a new type of gas water heater includes a housing 1. A quiet sound box 2 is arranged inside the housing 1. A burner 3 and a heat exchanger 4 are respectively installed at the bottom and top of the quiet sound box 2. The quiet sound box 2 includes a quiet outer shell 5 and a quiet inner shell 6. A quiet cavity is formed between the quiet outer shell 5 and the quiet inner shell 6. A quiet component 7 is also arranged inside the quiet inner shell 6. An exhaust component is also arranged at the top of the heat exchanger 4.

[0024] A gas inlet pipe 23 connected to the burner 3 is arranged at the bottom of the housing 1. When the gas water heater works, gas enters the burner 3 from the gas inlet pipe and burns inside, and burns fully inside the quiet sound box 2. The generated hot gas rises and passes through the heat exchanger 4 to carry out the heating work. During the working process, the double-layer quiet sound box 2 and the quiet component 7 inside it can effectively reduce the noise during the combustion process to improve the use comfort.

[0025] The quiet component 7 includes two groups of sound insulation boards 8 arranged in left-right mirror symmetry. The sound insulation board 8 includes a vertically arranged vertical board 81. Inclined boards 82 inclined towards the outside are arranged at the top and bottom of the vertical board 81. The bottom and top of the quiet component 7 are open-mouthed and respectively cover the top of the burner 3 and the bottom of the heat exchanger 4. The hot gas generated by combustion can fully enter between the two sound insulation boards 8. Sealing cavities 9 are opened inside the two sound insulation boards 8. Inert gas, specifically argon, is filled in the sealing cavities 9 to further play a sound insulation role.

[0026] Between two inclined plates 82 of the sound insulation board 8, two vertically arranged support plates 10 are fixedly connected. On the front and rear sides of the two support plates 10, between the two inclined plates 82, there are sealing plates 11. The two sealing plates 11 and the two inclined plates 82 form a sealed cavity 12. Inside the cavity 12, there is sound insulation material (not shown in the figure), specifically high-temperature resistant sound insulation cotton. By setting the sound insulation material, the sound insulation effect can be further improved.

[0027] Between the two sound insulation boards 8, there are several partition plates 13. The partition plates 13 divide the interior of the silent part 7 into several independent spaces. When the burner 3 burns, the hot gas generated does not directly contact the sound insulation inner shell. While the hot gas plays a role in sound insulation, it can reduce the loss of heat, and the hot gas can rise in several separate spaces, which can evenly heat the heat exchanger 4 and ensure the heat exchange effect of the heat exchanger 4.

[0028] The heat exchanger 4 includes mounting plates 14 arranged at the left and right ends of the top of the silent box 2. Between the two mounting plates 14, there is a heat exchange tube 15 arranged in an S shape. At its two ends, there are a water inlet pipe 16 and a water outlet pipe 17. On the heat exchange tube 15, there are several heat exchange fins 18. At the top of the front and rear sides of the silent outer shell 5, there are covering parts 19 covering both sides of the heat exchanger 4. The heat exchange tube 15 and the heat exchange fins are placed in the sealed space formed by the mounting plates 14 and the covering parts 19 to ensure its heat exchange effect.

[0029] The exhaust air assembly includes a smoke collecting hood 20 fixedly connected to the top of the covering part 19 and the mounting plate 14. At the outlet end of the smoke collecting hood 20, there is an exhaust fan 21 and an exhaust duct 22, which can effectively discharge the smoke generated by combustion.

[0030] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
