[0032] The exhaust pipe 2 has an exhaust channel 21 inside. The exhaust pipe 2 can be inserted into the outer shell 1 through the positioning part. The middle part of the exhaust pipe 2 is provided with a top part 22 that can abut against the top surface of the outer shell 1 when it is inserted into the outer shell 1. The bottom of the exhaust pipe 2 is provided with a second positioning part 23 that can abut against the bottom surface of the positioning part to prevent the exhaust pipe 2 from falling off the top of the outer shell 1.

[0033] Flange cover 3, which can be snapped onto the outer shell 1, is provided with a pressing part 31 that can be inserted into the first positioning part 13 from the opening 14 and lock the exhaust pipe 2 in cooperation with the wall of the first positioning part 13.

[0034] The mounting connector 4 is connected to the flange 12. The mounting connector 4 is also provided with a locking element that can lock the mounting connector 4, the flange cover 3 and the outer shell 1.

[0035] During use, this integrated and easy-to-install water heater casing provides protection and support for each component through the receiving cavity 11 of the casing 1. The exhaust pipe 2 is aligned with the opening 14, and then the exhaust pipe is snapped into the first positioning part 13. The top part 22 and the second positioning part 23 of the exhaust pipe 2 ensure that the exhaust pipe 2 is locked in the vertical direction. The flange cover 3 is installed on the casing 1 by snap-fit, and the top pressing part 31 is used to clamp the body of the exhaust pipe 2. Finally, the flange cover 3 is connected and locked to the casing 1 by the installation connector 4 and the locking part. The modular installation is convenient.

[0036] The first positioning part 13 includes an arc-shaped plate 131 extending downward along the top surface of the outer casing 1 and connecting plates 132 extending towards the flange 12 along the left and right ends of the arc-shaped plate 131. The groove walls of the arc-shaped plate 131 and the two connecting plates 132 form a slot 133 that can accommodate the exhaust pipe 2. The opening 14 is disposed between the two connecting plates 132. The arc-shaped plate 131 is configured such that its inner side can abut against the outer side wall of the exhaust pipe, and the two connecting plates 132 are used for guiding and positioning.

[0037] The outer casing 1 has a mounting step 15 on its top surface. The flange cover 3 includes a cover plate 32 that can be connected to the mounting step 15. The cover plate 32 has a support plate 33 extending toward the flange 12. The pressing part 31 is a top plate extending downward along the cover plate 32 into the first positioning part 13. The top plate has an arc-shaped pressing surface 311 that can abut against the outer wall of the exhaust pipe. The mounting step 15 has a connecting hole 151 for connecting a locking component. The support plate 33 has a first insertion hole 331 for inserting a locking component. The locking component is a screw, which facilitates locking. The mounting step 15 facilitates positioning and snapping. The cover plate 32 can be snapped into the outer casing 1 via the mounting step 15. The support plate 33 is used to support the flange 12, providing better support. The arc-shaped pressing surface 311 of the top plate can be clamped together, making the connection more stable.

[0038] The top abutment 22 is a convex ring located in the middle of the exhaust pipe 2, and when the exhaust pipe 2 is connected in place, the bottom surface of the convex ring abuts against the top surface of the outer casing 1. The convex ring facilitates positioning and locking.

[0039] The second positioning part 23 is a clamping plate set at the bottom of the exhaust pipe 2. The upper side of the clamping plate contacts the bottom surface of the arc plate 131 and part of the bottom surface of the two connecting plates 132. This arrangement can form a top-supported state, avoid shaking, and facilitate installation.

[0040] The mounting connector 4 includes a first support plate 41 that can fit against the flange 12 and a second support plate 42 that can be bent and extended at an angle relative to the first support plate 41. Multiple locking holes 43 are provided at the connection between the first support plate 41 and the second support plate 42. The first support plate 41 has a second insertion hole 411 through which a locking component can pass. The locking holes 43 facilitate the installation of the front panel. The second insertion hole 411 facilitates the insertion of screws and positioning.

[0041] The exhaust pipe 2 is provided with multiple exhaust holes 24, which penetrate the body of the exhaust pipe 2 radially. The exhaust pipe 2 also has multiple outer edges 25 on its outer periphery, one section of which connects to the outer periphery of the exhaust holes 24. The raised outer edges 25 effectively prevent external wind and rain from entering the exhaust channel 21 through the exhaust holes 24, while the exhaust holes 24 also assist in exhaust.

[0042] The multiple exhaust holes 24 are arranged in multiple rows, with a gap between the two exhaust holes 24 arranged vertically. The outer edge 25 is located on the upper side of the exhaust hole 24 and extends outward at an angle. This arrangement allows the exhaust holes 24 to discharge gas from the exhaust channel 21 more evenly and effectively.

[0043] The outer wall of the exhaust pipe 2 is also provided with a connecting part 26, and the connecting part 26 is provided with a sliding groove 261. The water heater shell also includes a cover 5 that can close to the top of the exhaust pipe 2 to seal the exhaust channel 21. The cover 5 is provided with multiple downward-extending retaining plates 51, each of which can be engaged into the sliding groove 261 and slide up and down along the sliding groove 261. The cover 5 prevents rainwater from flowing back into the internal components through the exhaust channel 21 when the gas water heater is used outdoors, making it safer. The cover 5 is positioned by the cooperation of the retaining plates 51 and the sliding groove 261, which facilitates the installation and positioning of the cover 5.

[0044] The exhaust pipe 2 is a one-piece molded structure, which is easy to process.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
