[0024] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0025] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0026] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0027] The embodiment of the present invention provides a fan assembly, such as Figure 1 and Figure 2 As shown, the fan 100 and the air guide base 200 are provided with an air guide channel 210. The air guide channel 210 has an inlet end and an outlet end. The inlet end of the air guide channel 210 is connected to the air outlet 110 of the fan 100. The air flow blown out by the fan 100 will enter the air guide channel 210. The air guide channel 210 is used to guide the air flow to be blown out evenly from the outlet end of the air guide channel 210. Therefore, the air outlet 110 of the fan 100 of this embodiment does not blow air directly outward. The air guide channel 210 allows the air blown out by the fan 100 to enter the combustion chamber relatively evenly, so that the gas can be burned fully and evenly.

[0028] In some embodiments, the air outlet 110 of the fan 100 and the inlet end of the air guide channel 210 are both arranged horizontally, and the outlet end of the air guide channel 210 is arranged vertically. The air guide channel 210 has an air guide wall 211 opposite the air outlet 110 of the fan 100, and the airflow blown out of the air outlet 110 will face the air guide wall 211. The air guide wall 211 gradually bends upward from a horizontal state to a vertical state, thereby guiding the airflow to be blown out evenly from the outlet end of the air guide channel 210, thereby playing a role in guiding the air.

[0029] At the same time, since the air outlet 110 of the fan 100 is arranged horizontally, the entire fan 100 is also arranged horizontally. Compared with the vertically arranged fan, the height of the entire fan assembly can be reduced, thereby reducing the space occupied in the height direction, making the height of the entire gas water heater smaller.

[0030] Furthermore, the cross-sectional shape of the air guide wall 211 is a quarter circle, so the air guide wall 211 can be tangent to the horizontal wall at the inlet end of the air guide channel 210 and the vertical wall at the outlet end of the air guide channel 210. The transition of the wall of the air guide channel 210 is smoother, so the airflow can be blown out from the outlet end of the air guide channel 210 more smoothly along the wall of the air guide channel 210, thereby improving the air guiding effect and reducing noise.

[0031] In some embodiments, the air outlet 110 of the fan 100 is plugged into the inlet end of the air guide channel 210, and the air flow is not easily blown out from the gap between the air outlet 110 and the air guide channel 210, thereby reducing air flow leakage. At the same time, the air flow at the two side walls of the air outlet 110 is directly blown into the air guide channel 210 without being blocked by the side walls of the air guide channel 210. Compared with plugging the inlet end of the air guide channel 210 into the air outlet 110 of the fan 100, noise can also be reduced.

[0032] In some embodiments, as Figure 3 and Figure 4 As shown, the fan assembly of this embodiment also includes a mounting plate 300, the fan 100 and the air guide seat 200 are both fixed to the bottom of the mounting plate 300, and the mounting plate 300 is provided with a through opening 301, the opening 301 is connected to the outlet end of the air guide channel, so that the airflow blown out from the outlet end of the air guide channel is blown out outward through the opening 301.

[0033] When installing the fan assembly, the installation of the fan 100 and the air guide seat 200 can be completed by fixing the mounting plate 300 to the bottom of the combustion chamber, which facilitates overall assembly.

[0034] Furthermore, downwardly extending support plates 310 are provided on both sides of the mounting plate 300. Air inlets 311 are provided through the support plates 310. The support plates 310 can stably support the mounting plate 300. At the same time, the support plates 310 can lift the fan 100 and the air guide seat 200 to a certain height, preventing the bottoms of the fan 100 and the air guide seat 200 from interfering with other structures inside the gas water heater, thereby providing sufficient air intake space for the air inlet at the bottom of the fan 100. Furthermore, the air inlet 311 on the support plates 310 allows outside air to pass through, allowing more air to enter the fan 100 from the air inlet at the bottom of the fan 100, thereby providing an adequate air supply.

[0035] Furthermore, the lower ends of the two support plates 310 are provided with laterally extending flanges 320. The flanges 320 can increase the contact area with the installation position, thereby more stably supporting the entire fan assembly. At the same time, the flanges 320 have a larger area and are easier to install.

[0036] Furthermore, a mounting hole 321 is provided on the flange 320 , and a connecting piece such as a screw can be passed through the mounting hole 321 and then fixed to the mounting position to achieve the installation of the entire fan assembly.

[0037] In some embodiments, the fan 100 and the air guide seat 200 are both fastened to the bottom of the mounting plate 300 by screws. Screw fixation has the advantages of easy assembly and convenient disassembly.

[0038] An embodiment of the present invention provides a gas water heater comprising a combustion chamber and a fan assembly according to any of the above-described embodiments. For a detailed description of the fan assembly, reference can be made to the above-described embodiments and will not be repeated here. The fan assembly is fixed to the bottom of the combustion chamber, and the outlet end of the air guide channel is connected to the combustion chamber. Thus, air blown by the fan enters the combustion chamber relatively evenly, allowing the gas in the combustion chamber to be fully and evenly burned.

[0039] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
