[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0039] In the description of the present application, it should be understood that the orientation description, such as the orientation or position relationship indicated by up, down, etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0040] In the description of the present application, the plural refers to two or more. If there is a description of first, second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0041] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0042] In order to effectively provide the necessary air flow for the combustion chamber, the fan is usually installed on the bottom side of the combustion chamber for air supply to the combustion chamber to ensure sufficient combustion of gas and normal operation of the water heater. During maintenance or replacement of the fan, the disassembly mode is often performed along the left and right directions of the gas water heater. However, since the fan is arranged adjacent to the side wall of the shell, and other devices are also arranged on the side of the fan away from the side wall of the shell, the side wall of the shell and the devices around the fan limit the operation space for disassembling the fan.

[0043] The traditional fan disassembly usually first disassembles the whole shell of the gas water heater, and then disassembles the fan, the whole operation process is complicated and difficult to operate, and a long time is needed, which reduces the disassembly efficiency of the fan. In addition, frequent disassembly of the shell of the gas water heater can easily expose other devices, increase the risk of misoperation or accidental damage, and also cause the device connection inside the gas water heater to be loose, causing the stability of the overall structure of the gas water heater to decrease.

[0044] To this end, referring to Figure 1 Some embodiments of the utility model provide a gas equipment 1000, which is suitable for a gas water heater 2000. Wherein, the gas water heater 2000 includes a shell 2100, and the shell 2100 is provided with a cavity 2110 for accommodating a fan 300, a combustion chamber 100, an electric control panel and the like. Referring to Figures 1 to 8 The gas equipment 1000 is described.

[0045] For the convenience of description, the following content is referred to the installation of the gas water heater 2000 to the use environment, the user stands towards the gas water heater 2000, the side of the gas water heater 2000 towards the user is front, the side away from the user is back, the side corresponding to the left hand of the user is left, the side corresponding to the right hand of the user is right, the side close to the ground is down (bottom), and the side away from the ground is up (top).

[0046] Referring to Figure 2 And Figure 3 In the embodiment of the utility model, the gas equipment 1000 includes a combustion chamber 100 and a fan 300, wherein the combustion chamber 100 can be installed with a burner, a heat exchanger and the like, and the gas can be combusted in the inner cavity of the combustion chamber 100 through the burner, so as to release heat. Specifically, the combustion chamber 100 is in the form of a box as a whole, and is fixed in the cavity 2110. In this embodiment, the combustion chamber 100 includes a side plate and a bottom plate 200, the side plate is surrounded to form a frame body, and the bottom plate 200 is connected to the bottom of the frame body. The bottom plate 200 is provided with an air inlet 210, which communicates with the inner cavity of the combustion chamber 100. Based on this, air can flow into the inner cavity of the combustion chamber 100 from the air inlet 210 to make the gas fully burn.

[0047] Continuing to refer to Figure 2 And Figure 3 In the embodiment of the utility model, the fan 300 is arranged on the lower side of the combustion chamber 100, and the fan 300 is provided with an air outlet 310. Based on this, it can be known from Figure 4 That when the fan 300 is connected to the bottom plate 200, the air outlet 310 communicates with the air inlet 210, and the fan 300 can deliver air to the inner cavity of the combustion chamber 100 through the air outlet 310.

[0048] To achieve detachable connection of the fan 300 and the bottom plate 200, with reference to Figure 2 and Figure 4 In the embodiment of the utility model, the bottom plate 200 is equipped with the first clamping part 220 and the positioning part 230, the fan 300 is equipped with the second clamping part 410 and the connecting part 420, the first clamping part 220 cooperates with the second clamping part 410, and the positioning part 230 cooperates with the connecting part 420. Specifically, the first clamping part 220 is arranged at intervals with the air inlet 210 along the front-back direction of the gas equipment 1000, and in one example, the first clamping part 220 is located at the rear side of the air inlet 210. The positioning part 230 is arranged at intervals with the air inlet 210 along the left-right direction of the gas equipment 1000, and in one example, the positioning part 230 is located at the right side of the air inlet 210.

It can be understood that when the fan 300 moves from front to back, the cooperation of the connecting part 420 and the positioning part 230 can play a role in left-right positioning on the one hand, which facilitates the alignment of the second clamping part 410 to the first clamping part 220, so that the second clamping part 410 can accurately clamp and cooperate with the first clamping part 220, and on the other hand, the cooperation of the connecting part 420 and the positioning part 230 can stop the fan 300 from continuing to move backward, thereby playing a role in front-back positioning, improving the assembly accuracy of the fan 300. The clamping and cooperation of the second clamping part 410 and the first clamping part 220 realize the fixation of the fan 300 and the bottom plate 200, making the disassembly and installation of the fan 300 very simple.

[0050] It should be noted that in the embodiment of the utility model, one of the first clamping part 220 and the second clamping part 410 is a buckle, and the other is a buckle position, and the buckle and the buckle position are buckled to realize the fixation of the fan 300. In this embodiment, the positioning part 230 can be a positioning protrusion, a positioning groove or other positioning structure, and the connecting part 420 can be set according to the specific form of the positioning part 230, for example, the positioning part 230 can be a positioning groove, and the connecting part 420 can be a positioning buckle matched with the positioning groove to realize buckling positioning. Specifically, the positioning part 230 and the connecting part 420 can be selected and set according to actual conditions.

[0051] It can be understood that, in the embodiment of the utility model, through the clamping of the second clamping part 410 and the first clamping part 220 and the positioning cooperation of the connecting part 420 and the positioning part 230, the disassembly operation of the fan 300 can be carried out along the front-back direction of the gas equipment 1000, avoiding the hindrance of the sidewall of the shell 2100 of the gas water heater 2000 and other devices to the disassembly process of the fan 300, when disassembling the fan 300, only the front side panel of the gas water heater 2000 needs to be opened to carry out the disassembly operation of the fan 300, realizing the disassembly of the fan 300 without disassembling the whole shell 2100, simplifying the disassembly process of the fan 300, not only reducing the disassembly difficulty, but also improving the disassembly efficiency of the fan 300.

[0052] In addition, based on the fact that the shell 2100 does not need to be disassembled when the fan 300 is disassembled, the disassembly frequency of the shell 2100 of the gas water heater 2000 is reduced, the risk of structural stability decline caused by frequent disassembly of the shell 2100 is effectively reduced, and the stability and durability of the overall structure of the gas water heater 2000 are improved.

[0053] Referring to Figure 3 and Figure 6 It can be understood that, in the embodiment of the utility model, the positioning part 230 is a first lug 231, and the first lug 231 is arranged towards the fan 300.

[0070] Correspondingly, with reference to Figure 4 , Figure 6 and Figure 7 In the embodiment of the utility model, the housing 400 is provided with an air outlet portion 440, and the air outlet 310 is formed at the central position of the air outlet portion 440. Specifically, the projection of the air outlet portion 440 and the projection of the mounting area 260 overlap in the up-down direction of the gas equipment 1000, and the projection shapes of both are rectangular. When the fan 300 is connected to the bottom plate 200, the air outlet portion 440 covers the mounting area 260, so that the air outlet 310 and the air inlet 210 are in communication. The air outlet portion 440 is arranged around the connection between the air outlet 310 and the air inlet 210, thereby reducing the possibility of air leakage and ensuring the air-tightness of the connection between the fan 300 and the combustion chamber 100. Wherein, Figure 6 The position shown by the dashed box in

[0071] With reference to Figure 7As shown in the utility model embodiment, the second lug 421 and the fourth lug 430 are located at two sides of the air outlet part 440, and the second clamping part 410 is formed on the air outlet part 440. Specifically, the shell 400 is a volute, the second lug 421 is protruded and formed on the right side surface of the air outlet part 440, the fourth lug 430 is protruded and formed on the surface of the volute, and the clamping tongue 411 is protruded and formed on the rear side surface of the air outlet part 440. It can be understood that the second lug 421, the fourth lug 430 and the clamping tongue 411 make the air outlet part 440 be effectively fixed in three different directions, thereby enhancing the stability and firmness of the installation of the fan 300.

[0072] Referring to Figure 3 and Figure 6 As shown in the utility model embodiment, the bottom surface of the bottom plate 200 is provided with the mounting plate 500. Specifically, the mounting plate 500 can be connected to the bottom plate 200 through screws, can be welded to the bottom plate 200, and can also be fixed to the bottom plate 200 through other fixed connection modes. The mounting plate 500 is provided with the through hole 510, the through hole 510 is communicated between the air inlet 210 and the air outlet 310, and the flange 250, the first lug 231 and the third lug 240 are all formed on the mounting plate 500. The mounting plate 500 is specifically a sheet metal part, and the sheet metal part can form the through hole 510, the flange 250, the first lug 231 and the third lug 240 through an integral molding process.

[0073] It can be understood that the fan 300 of the gas equipment 1000 supports multiple specifications, and based on this, the mounting plate 500 can be provided in multiple ways, so that the fan 300 of each specification has a corresponding mounting plate 500. When it is necessary to replace the fan 300 of different specifications, only the mounting plate 500 corresponding to the fan 300 needs to be replaced to realize the installation of the fan 300, thereby improving the flexibility and universality of the gas equipment 1000.

[0074] Referring to Figure 5 As shown in the utility model embodiment, the upper end surface of the clamping hook 2312 is in abutment with the second lug 421 to support the second lug 421. Specifically, in the embodiment, the upper end surface of the clamping hook 2312 can extend along the front-rear direction of the gas equipment 1000 to form a horizontal plane, thereby providing stable supporting force to the second lug 421.

[0075] Referring to Figure 8As shown, in the embodiment of the utility model, the clamping hook 2312 extends towards the front side of the gas equipment 1000. It can be understood that the inventor has known through experiments that if the width of the clamping hook 2312 along the front-rear direction of the gas equipment 1000 is too small, it will be difficult to support the second lug 421, and the second lug 421 is prone to dislocation. Therefore, in this embodiment, the width of the clamping hook 2312 along the front-rear direction of the gas equipment 1000 is w, which satisfies: w≥2mm, thereby ensuring that the clamping hook 2312 can support the second lug 421, and reducing the possibility of dislocation of the second lug 421.

[0076] The embodiment of the utility model further proposes a gas water heater 2000, which comprises the gas equipment 1000 of the above embodiment.

[0077] It can be understood that the gas water heater 2000 of the embodiment can make the disassembly operation of the fan 300 along the front-rear direction of the gas equipment 1000 by adopting the gas equipment 1000 of the above embodiment, avoiding the obstruction of the side wall of the shell 2100 and other devices of the gas water heater 2000 to the disassembly process of the fan 300. When disassembling the fan 300, only the front side cover plate of the gas water heater 2000 needs to be opened to perform the disassembly operation of the fan 300, realizing the disassembly of the fan 300 without disassembling the entire shell 2100, simplifying the disassembly process of the fan 300, not only reducing the disassembly difficulty, but also improving the disassembly efficiency of the fan 300, and improving the maintainability of the gas water heater 2000. In addition, by reducing the disassembly frequency of the shell 2100 of the gas water heater 2000, the risk of structural stability decline caused by frequent disassembly of the shell 2100 is effectively reduced, thereby improving the stability and durability of the overall structure of the gas water heater 2000.

[0078] Since the gas water heater 2000 adopts all the technical solutions of the gas equipment 1000 of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0079] The above describes the embodiments of the utility model in detail in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the utility model.
