When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] In the related art, the fan of the gas equipment is inserted into the burner assembly axially inward along the air inlet of the burner assembly, which requires the peripheral edge of the air outlet end of the fan to be fully inserted into the air inlet, resulting in problems of great assembly difficulty and low assembly efficiency.

[0051] To this end, the present invention proposes a gas appliance that aims to reduce the installation difficulty of the fan 3 and the burner assembly 1 and improve assembly efficiency. It is understandable that the gas appliance is not limited to a specific type of appliance, for example, it can be a gas water heater, a gas wall-mounted boiler, or other types of gas appliances.

[0052] In the embodiment of the present utility model, Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, the gas appliance includes a burner assembly 1, a mounting frame 2, and a fan 3. The burner assembly 1 is provided with an air inlet 101; the mounting frame 2 is fixedly connected to the burner assembly 1 and is disposed around the periphery of the air inlet 101; the mounting frame 2 is provided with a slot 21; the fan 3 has an air outlet 301 and a connecting flange 311 disposed around the periphery of the air outlet 301, and the connecting flange 311 is provided with a snap-fit ​​portion 3111. The snap-fit ​​portion 3111 is inserted into the slot 21 along a first direction, so that the connecting flange 311 is mated and assembled with the mounting hole 2; the first direction forms an angle with the axial direction of the air inlet 101.

[0053] In this embodiment, the air inlet 101 of the burner assembly 1 is used to connect to the air outlet 301 of the fan 3. The fan 3 can blow external air into the burner assembly 1 to mix with the gas in the burner assembly 1 for combustion. It can be understood that the burner assembly 1 can include a combustion chamber housing 11 and a burner body disposed within the combustion chamber housing 11. The air inlet 101 is opened on the wall of the combustion chamber housing 11. Optionally, the air inlet 101 can be disposed at the top or bottom of the combustion chamber housing 11.

[0054] The mounting frame 2 is fixedly connected to the burner assembly 1 and is disposed around the periphery of the air inlet 101, connecting the fan 3 to the combustion chamber housing 11. Optionally, the mounting frame 2 is a frame-shaped structure adapted to the shape of the air inlet 101. The mounting frame 2 can be secured to the outer wall of the combustion chamber housing 11 by welding, screwing, or riveting. The mounting frame 2 has a communication port that communicates with the air inlet 101, thereby facilitating communication between the air inlet 101 and the air outlet 301 when docked and assembled with the connection flange 311 of the fan 3. Optionally, the mounting frame 2 can be constructed of sheet metal, stainless steel, or the like.

[0055] The fan 3 has a connecting flange 311 disposed around the periphery of the air outlet 301. It is understood that the connecting flange 311 is equivalent to the outlet port of the fan 3 volute. Optionally, the connecting flange 311 is integrally formed with the fan 3 volute. This can reduce the number of intermediate components connecting the fan 3 to the burner assembly 1, simplifying the assembly steps and saving costs. In actual application, the connecting flange 311 can be configured as a frame-shaped structure that adapts to the shape of the air outlet 301. When the connecting flange 311 is assembled with the mounting frame 2, the connecting flange 311 can be substantially the same shape as the mounting frame 2.

[0056] The fixing part 3111 is fixed to the fixing portion 3111 so as to prevent the loosening of the fixing portion 3111 and the loosening of the fixing portion 3112.

[0057] It should be noted that the first direction in this embodiment is not limited to a specific direction. Taking the air inlet 101 located at the top or bottom of the burner housing 11 as an example, the first direction can be the front-to-back direction, the left-to-right direction, the oblique front-to-back direction, the oblique left-to-right direction, or some other direction. As an example, to further enhance assembly convenience, the first direction is preferably perpendicular to the axial direction of the air inlet 101. The installation direction of the fan 3 can be parallel to the wall surface where the air inlet 101 is located, which further facilitates the installation operation.

[0058] In practical applications, the specific structure of the slot portion 21 can be determined based on actual conditions, such as a hook structure, a socket slot structure, or some other structure. The location of the slot portion 21 can also be determined based on actual conditions, such as being located in front of, on the left side, on the right side, or on the rear side of the air inlet 101. The number of slot portions 21 can also be determined based on actual conditions, such as being one, two, or more. The slot portion 21 can be a separate structure or an integrally formed structure with the mounting frame 2.

[0059] In practical applications, the specific structure of the clamping portion 3111 can be determined based on actual circumstances, for example, it can be a hook structure, an insert structure, or some other structure. The position of the clamping portion 3111 can be determined based on the position of the clamping slot 21. Accordingly, the number of clamping portions 3111 can also be determined based on the number of clamping slots 21, and the number of the two can be the same or different. The clamping portion 3111 can be a separate structure or an integrally formed structure with the connecting flange 311.

[0060] In summary, in the gas equipment of the technical solution of the present invention, a mounting frame 2 is provided on the periphery of the air inlet 101 of the burner assembly 1, and the mounting frame 2 is provided with a slot portion 21. A snap-fit ​​portion 3111 is provided on the connecting flange 311 on the periphery of the air outlet 301 of the fan 3. The snap-fit ​​portion 3111 can be inserted into the slot portion 21 along a first direction that is angled with the axial direction of the air inlet 101, and when the snap-fit ​​portion 3111 is snap-fitted with the slot portion 21, the connecting flange 311 is docked and assembled with the mounting frame 2. Therefore, during assembly, the fan 3 only needs to be moved along the first direction outside the burner assembly 1 so that the snap-fit ​​portion 3111 is inserted into the slot portion 21 of the mounting frame 2, and the connecting flange 311 can be docked and assembled with the mounting frame 2 without inserting the entire air outlet end of the fan 3 into the air inlet 101, thereby simplifying the insertion difficulty and improving the assembly efficiency.

[0061] To further enhance assembly convenience, Figures 1 to 4 as well as Figure 8 In one embodiment, the air inlet 101 is located at the top or bottom of the burner assembly 1; the first direction is the front-to-back direction of the burner assembly 1, and the clamping portion 3111 is inserted into the clamping slot 21 from front to back.

[0062] It can be understood that the air inlet 101 is located at the top or bottom of the burner assembly 1, and the axial direction along the air inlet 101 is the up and down direction of the burner assembly 1. Optionally, the combustion chamber housing 11 includes a bottom frame and a cover plate, and the front side of the bottom frame is open. During assembly, the cover plate is placed on the open position and installed with the bottom frame. It can be understood that the cover plate is the front side of the burner assembly 1, and the side opposite to the cover plate is the rear side of the burner assembly 1. In this embodiment, the first direction is the front-to-back direction of the burner assembly 1, and the clamping portion 3111 is inserted into the clamping slot portion 21 from front to back, so that the fan 3 is assembled to the burner assembly 1 along the front-to-back direction. Its assembly direction is consistent with the assembly direction of the cover plate. When the whole machine is assembled, the burner assembly 1 and the fan 3 can be assembled without additional flipping operation, which simplifies the assembly steps and is more conducive to automated assembly.

[0063] It should be noted that the directions (up-down, front-back, and left-right) mentioned in this embodiment refer to the directions of the gas appliance during normal use. However, during assembly, the gas appliance is in a horizontal position. In this case, the front-back direction refers to the up-down direction during the assembly process, and the up-down direction refers to the front-back direction during the assembly process. That is, during assembly, the engaging portion 3111 is inserted into the engaging slot 21 from top to bottom, which facilitates assembly and reduces assembly difficulty.

[0064] Furthermore, if Figures 1 to 4 as well as Figure 8 The card slot portion 21 is a hook structure with the slot opening facing the front. Optionally, the card slot portion 21 includes a connecting arm 211 and a holding arm 212. One end of the connecting arm 211 is connected to the mounting frame 2, and the other end is extended away from the burner assembly 1; the holding arm 212 is connected to the end of the connecting arm 211 away from the mounting frame 2, and is arranged opposite to the mounting frame 2 to form a clamping space for holding the clamping portion 3111. Among them, the connecting arm 211 is arranged opposite to the slot opening to abut against the limiting clamping portion 3111 to prevent the clamping portion 3111 from being over-inserted and causing the connecting flange 311 to be misaligned with the mounting frame 2. The holding arm 212 is opposite to the mounting frame 2 and plays a role in supporting and lifting the clamping portion 3111, so that the flange surface of the connecting flange 311 abuts and cooperates with the surface of the mounting frame 2 to ensure the reliability of the connection between the two.

[0065] In order to ensure the connection reliability between the connecting flange 311 and the mounting frame 2, as shown in FIG. Figures 1 to 4 as well as Figures 7 to 9 In one embodiment, the slot portion 21 is integrally connected to the side of the mounting frame 2 facing away from the burner assembly 1 and is located on the outside of the air inlet 101; the clamping portion 3111 protrudes from the side edge of the connecting flange 311. When the clamping portion 3111 is inserted into the slot portion 21, the flange surface of the connecting flange 311 abuts against the surface of the mounting frame 2 facing away from the burner assembly 1.

[0066] In this embodiment, the slot portion 21 is located on the side of the mounting frame 2 facing away from the burner assembly 1. It can be understood that the slot portion 21 is located on the outer surface of the mounting frame 2 and outside the air inlet 101, so that the slot portion 21 does not interfere with the air inlet 101. The clamping portion 3111 protrudes from the side edge of the connecting flange 311, so the clamping portion 3111 is located outside the air outlet 301. In other words, the assembly of the clamping portion 3111 and the slot portion 21 does not interfere with the air outlet 301.

[0067] During assembly, when the clamping portion 3111 is inserted into the clamping slot portion 21 along the first direction, the flange surface of the connecting flange 311 will move along the first direction against the surface of the mounting frame 2 until the clamping portion 3111 and the clamping slot portion 21 are clamped in place, so that the flange surface of the connecting flange 311 abuts against the surface of the mounting frame 2, thereby ensuring the strength of the fit between the two and preventing air leakage.

[0068] In order to further improve the assembly reliability of the fan 3 and the burner assembly 1, as Figures 7 and 8 In one embodiment, the mounting frame 2 is provided with a card slot portion 21 on both the left and right sides of the air inlet 101; the left and right sides of the connecting flange 311 are respectively provided with a card connection portion 3111, and the two card connection portions 3111 are respectively inserted into the corresponding card slot portion 21.

[0069] With such an arrangement, during assembly, the connecting flange 311 can simultaneously drive the clamping parts 3111 on both sides and the two slot parts 21 to be inserted, so that the force on the fan 3 is more balanced during the insertion process, which can improve the insertion stability and prevent skewing; after being inserted into place, the connection force distribution between the connecting flange 311 and the mounting frame 2 is more balanced, and the assembly reliability of the two can be improved.

[0070] Furthermore, if Figures 5 to 9 The mounting frame 2 is provided with a limiting groove portion 22 at the rear side of the air inlet 101 ; when the clamping portion 3111 is inserted into the clamping groove portion 21 , the limiting groove portion 22 clamps the rear edge of the limiting connecting flange 311 .

[0071] In this embodiment, the limiting groove 22 is located at the rear side of the air inlet 101. It is understandable that during the assembly process, the limiting groove 22 is located below the air inlet 101. When the connecting flange 311 drives the left and right clamping portions 3111 to insert into the clamping grooves 21 on both sides, the rear edge of the connecting flange 311 is clamped in the limiting groove 22. At this time, the limiting groove 22 can play a supporting and limiting role for the connecting flange 311, preventing the connecting flange 311 from moving too far and being misaligned with the installation frame 2. Optionally, the structure of the limiting groove 22 can be the same as or different from that of the clamping groove 21.

[0072] It can be understood that the two slot portions 21 are located on the left and right sides of the mounting frame 2, and the limit slot portion 22 is located on the rear side of the mounting frame 2, so that the connecting flange 311 and the mounting frame 2 are connected through three connection positions, thereby improving the connection strength between the connecting flange 311 and the mounting frame 2, and thereby improving the assembly reliability of the fan 3 and the burner assembly 1.

[0073] To facilitate insertion, Figures 5 to 8 In one embodiment, the slot portion 21 is provided with a guide portion 213 at its slot opening for guiding the insertion of the engaging portion 3111. Optionally, the guide portion 213 is a guide plate, which forms an "inverted eight" shape at the slot opening of the slot portion 21 to facilitate insertion of the engaging portion 3111. Optionally, the guide portion 213 is connected to the free end of the holding arm 212.

[0074] In order to further improve the assembly strength of the fan 3 and the burner assembly 1, as Figures 1 to 4 as well as Figures 7 to 9In one embodiment, the mounting frame 2 is provided with a first mounting plate 23 extending away from the burner assembly 1, and the first mounting plate 23 is located in front of the air inlet 101; the first mounting plate 23 is provided with a first mounting hole 231 extending along the first direction; the front edge of the connecting flange 311 is provided with a second mounting hole 3112; when the clamping portion 3111 is inserted into the clamping groove portion 21, the first mounting plate 23 is located in the air outlet 301 and is abutted against the front edge of the connecting flange 311, and the connecting flange 311 and the first mounting plate 23 are locked and fixed by fasteners passing through the second mounting hole 3112 and the first mounting hole 231.

[0075] With this design, in addition to the clamping connection between the clamping portion 3111 and the slot portion 21, the connecting flange 311 and the mounting frame 2 are also supported and limited by the first mounting plate 23 and locked with fasteners, further strengthening the connection strength between the fan 3 and the burner assembly 1.

[0076] In addition, in this embodiment, the first mounting plate 23 is arranged on the front side of the air inlet 101. During the assembly process, the first mounting plate 23 is located above the air inlet 101, and the first mounting hole 231 is extended up and down, so that the fastener can be assembled from top to bottom, reducing the difficulty of assembly; at the same time, the assembly direction of the fastener is consistent with the insertion direction of the clamping portion 3111, and there is no need to perform multiple flipping operations, so that both the insertion operation and the fastener assembly operation are performed from top to bottom, which is more conducive to assembly automation and improves assembly efficiency.

[0077] Optionally, the number of the first mounting hole 231 and the second mounting hole 3112 is two, so as to improve the locking strength.

[0078] Optionally, the fastener is a screw or a bolt.

[0079] In order to improve the sealing performance of the connection between the connecting flange 311 and the mounting frame 2, as shown in FIG. Figure 4 and Figure 9 In one embodiment, a flange surface of the connecting flange 311 is provided with a mounting groove 3113, and the mounting groove 3113 is arranged around the air outlet 301; the gas equipment also includes a sealing member installed in the mounting groove 3113 to seal the connecting flange 311 and the mounting frame 2.

[0080] In actual application, a sealing member can be provided in the mounting groove 3111. When the clamping portion 3111 is inserted into the clamping groove portion 21, the connecting flange 311 is docked with the mounting frame 2. At this time, the sealing member is compressed by a certain amount by the connecting flange 311 and the mounting frame 2 to achieve sealing, thereby preventing the air volume of the fan 3 from leaking out.

[0081] Optionally, the sealing member is a rubber member and is fixed in the mounting groove 3111 by bonding.

[0082] In one embodiment, if Figure 1 、 Figure 5 as well as Figure 9 The fan 3 includes a fan casing 31, an impeller 32 and an air inlet ring 33. The fan casing 31 is provided with an air outlet 301. The fan casing 31 forms a connecting flange 311 on the periphery of the air outlet 301; the clamping portion 3111 and the connecting flange 311 are an integral structure; the impeller 32 is arranged in the fan casing 31; and the air inlet ring 33 is installed on the fan casing 31.

[0083] In this embodiment, the fan housing 31 is an integrated housing structure. The connecting flange 311 is the air outlet end of the fan housing 31. The clamping portion 3111 is integrally formed with the connecting flange 311. When the connecting flange 311 is connected to the mounting frame 2, the fan housing 31 of the fan 3 is actually directly mounted on the mounting frame 2, eliminating the need for additional connecting structures and simplifying the assembly process. Optionally, the fan housing 31 can be integrally injection molded.

[0084] In actual use, the fan housing 31 has an open opening on one axial side. After the fan housing 31 is integrally formed, the impeller 32 is installed in the fan housing 31 through the open opening. The air inlet ring 33 is then installed in the open opening and fastened to the fan housing 31 by screws. The impeller 32 drives the airflow, while the air inlet ring 33 is installed in the fan housing 31 to allow air in.

[0085] In one embodiment, if Figure 1 、 Figure 5 as well as Figure 9 The gas equipment further includes a bottom shell 6 and a fixing bracket 5 , the burner assembly 1 is mounted on the bottom shell 6 , and the fixing bracket 5 fixedly connects the fan housing 31 and the bottom shell 6 .

[0086] As will be understood, the bottom shell 6 serves as the outer shell of the gas equipment, and is used to house internal components of the gas equipment, such as the burner assembly 1, the fan 3, and the heat exchanger. The rear sidewall of the combustion chamber housing 11 of the burner assembly 1 is mounted to the rear sidewall of the bottom shell 6, and the fan 3 is mounted to the bottom shell 6 via a fixing bracket 5.

[0087] The fixing bracket 5 is fixed to the integrated fan casing 31 by screws, which is stronger than fixing it on the air inlet ring 33 in the related art, and will not cause deformation and air leakage caused by pulling the air inlet ring 22 during transportation.

[0088] Optionally, the fixing bracket 5 is a sheet metal part or a stainless steel structure.

[0089] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
