Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a gas water heater shell and a gas water heater. Background Art

[0002] Gas water heaters require an air intake structure on the housing, typically located on the back or sides. However, in practice, there may be a lack of air intake space on the back or sides of the water heater. For example, a gas water heater is installed between a cabinet and a wall, integrated with the cabinet to achieve an integrated effect. This installation method does not meet the requirements for gas water heater use because the left, right, and back sides of the water heater are against the wall, leaving no air intake space on these three sides. Furthermore, gas water heaters generate a loud noise when the gas is burning, which can be a negative experience for users.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a gas water heater shell, which can supply gas to the gas water heater from the bottom and reduce the noise of the gas water heater when in use.

[0005] Another object of the present invention is to provide a gas water heater, which includes the above-mentioned gas water heater shell, which can take in air from the bottom and reduce the noise of the gas water heater when in use.

[0016] Compared with the prior art, the advantages and beneficial effects of the embodiments of the present invention are:

[0017] The gas water heater shell and the gas water heater provided by the embodiment of the present invention can take in air through the second air inlet provided at the bottom of the shell. The air enters the air inlet channel along the first air inlet and flows into the shell from the air outlet at the top of the air inlet channel to supply air to the burner of the gas water heater. The gas water heater shell and the gas water heater provided by the embodiment of the present invention can adapt to situations where air cannot be taken in from the back or the sides, such as embedded gas water heaters. In addition, when the gas water heater is running, the internal noise has only one path to be transmitted outward, that is, it enters the air inlet channel from the top air outlet of the air inlet channel, and then is transmitted out from the first air inlet and the second air inlet at the bottom of the air inlet channel. In this process, the noise sound waves lose a lot of energy over a long time and a long distance in the air inlet channel, and then are transmitted to the outside of the machine, which can achieve a significant noise reduction function.

For the convenience of description, the definition Figure 1 The upward arrow is in the upward direction, and the opposite direction is downward; the direction away from the page is forward, and the opposite direction is backward. A combustion chamber is provided within the housing 1, and a vertical air inlet channel 2 is provided on at least one side of the combustion chamber. In this embodiment, the air inlet channel 2 is provided on both sides of the housing 1 to increase the amount of air entering. The top of the air inlet channel 2 is provided with an air outlet 20 that communicates with the combustion chamber, and the bottom of the air inlet channel 2 is provided with a first air inlet 21. The bottom of the housing 1 is provided with a second air inlet 22 that is connected to the first air inlet 21.

[0029] The gas water heater housing provided by the embodiment of the present invention can take in air through the second air inlet 22 provided at the bottom of the housing 1, and the air flow direction is as follows: Figure 3 As shown by the arrow in the figure, air enters the air inlet channel 2 along the first air inlet 21 and flows into the housing 1 from the air outlet 20 at the top of the air inlet channel 2 to supply gas to the burner of the gas water heater. The gas water heater housing provided by the embodiment of the utility model can adapt to the situation where there is no air intake on the back or both sides, such as embedded gas water heaters (such as Figure 5Furthermore, when the gas water heater is operating, internal noise has only one outward transmission path: entering the air inlet duct 2 from the top air outlet 20, and then exiting through the first air inlet 21 and the second air inlet 22 at the bottom of the air inlet duct 2. During this process, the noise waves experience significant energy loss over a long period of time within the air inlet duct 2 before being conducted out of the device, achieving significant noise reduction.

[0030] In one embodiment of the present invention, the air inlet channel 2 is provided inside one side or both sides of the housing 1 , that is, is integrally formed with the housing 1 .

[0031] For manufacturing convenience, Figure 1-Figure 3 As shown, in another embodiment of the present invention, the housing 1 includes a main board 11, a top plate 12 extending forward from the top of the main board 11, a bottom plate 13 extending forward from the bottom of the main board 11, and side plates 14 extending forward from both sides of the main board 11. The main board 11, top plate 12, bottom plate 13, and side plates 14 form an opening on the front side of the housing 1. The opening on the front side of the housing 1 is covered by a front panel (not shown), which is used to enclose the functional components of the gas water heater within the housing 1 and to install the display and control components of the gas water heater. Side inner plates 15 are provided inside the side plates 14 that provide the air inlet duct 2. In this embodiment, these side inner plates 15 are provided inside both side plates 14. A sealed air inlet duct 2 is formed between the side inner plates 15 and the side plates 14. The side inner plates 15, the main board 11, the bottom plate 13, the top plate 12, and the front panel enclose the combustion chamber. Furthermore, a first raised portion 151 protruding toward the combustion chamber is provided on the inner side of the top of the side inner panel 15. The first raised portion 151 is provided with a plurality of through holes, forming the air outlet 20 to achieve uniform air discharge. Furthermore, the bottom of the side inner panel 15 abuts against the top of the bottom panel 13. A second raised portion 152 protruding toward the combustion chamber is provided on the bottom of the side inner panel 15. The first air inlet 21 is formed between the second raised portion 152 and the bottom of the side panel 14. The first raised portion 151 and the second raised portion 152 can increase the amount of air entering. The bottom panel 13 is provided with a plurality of through holes, forming the second air inlet 22. The position of the second air inlet 22 corresponds to that of the first air inlet 21.
