Description

Technical Field

[0001] This utility model relates to the field of wall-hung boiler technology, and in particular to a wall-hung boiler. Background Technology

[0002] A wall-hung boiler is a type of water heater that uses natural gas as its energy source. It has a powerful home heating function and is gradually becoming more popular.

[0003] Typically, the air inlet duct and exhaust duct of a wall-hung boiler are coaxially arranged and extend outdoors. Air enters the boiler through the air inlet duct, and flue gas is discharged through the exhaust duct. Rainwater or condensation formed between the air inlet and exhaust ducts can flow into the air inlet duct and potentially back into the boiler casing, damaging components and even affecting its safe operation. Current wall-hung boilers are equipped with a water collection tray to collect water flowing back into the boiler casing from the air inlet duct. A drain pipe is usually connected to the bottom or side of the water collection tray to drain the water and prevent it from flowing onto the internal components. However, the existing water collection tray with a connected drain pipe has a complex installation structure and is costly.

[0004] Therefore, it is necessary to propose a wall-hung boiler to solve at least one of the above problems. Utility Model Content

[0051] In the wall-mounted boiler 1 provided in this embodiment, the air inlet connector 402 and the exhaust connector 401 are coaxially arranged. The air inlet connector 402 is sleeved on the outside of the exhaust connector 401 to form a single component. Thus, only one component needs to be installed when installing on the top plate 30. Correspondingly, the air inlet pipe 60 and the exhaust pipe 50 are also coaxially arranged and connected to the air inlet connector 402 and the exhaust connector 401. The water collection tray 10 is provided with a through hole 106. The part of the exhaust connector 401 that extends into the housing 100 passes through the through hole 106 of the water collection tray 10 and connects to the exhaust part 701 of the heat exchanger 70. The gap between the water collection tray 10 and the air inlet connector 402 and the exhaust connector 401 is opposite, and the water is collected at the lower part of the air inlet connector 402.

[0059] In this embodiment, the side wall 102 of the water collection tray 10 is provided with at least one straight edge section 105, and the drainage part 103 is disposed on the straight edge section 105. When the water collection tray 10 is installed, the straight edge section 105 is positioned close to the side of the surrounding plate 1001, which facilitates the positioning of the drainage part 103 close to the surrounding plate 1001. When water is discharged from the drainage part 103, it contacts the surrounding plate 1001 and then flows downward along the surrounding plate 1001 and is discharged. Specifically, the straight edge section 105 of the side wall 102 of the water collection tray 10 is positioned close to the back plate 80 of the surrounding plate 1001, so that when water is discharged from the drainage part 103, it contacts the back plate 80 and then flows downward along the back plate 80 and is discharged.

A drainage gap 902 is provided at the connection between the back plate 80 and the bottom shell 90. Water discharged from the water collection tray 10 flows downward along the back plate 80 to the connection between the back plate 80 and the bottom shell 90, and is discharged from the casing 100 of the wall-hung boiler 1 through the drainage gap 902 at the connection. The bottom shell 90 is also provided with a mounting boss 901, such as a boss formed by stamping the bottom shell 90. Some components on the bottom shell 90 that need to be installed can be mounted on the boss to prevent water flowing down the back plate 80 from not being able to drain out of the drainage gap 902 in time and flowing onto the bottom shell 90 and contacting the components installed inside the casing 100. The bottom shell 90 is also provided with a drainage hole to further drain water from the bottom shell 90.
