[0002] A wall-hung boiler is a device that uses gas to heat domestic water and provide heating. At present, more and more people begin to use wall-hung boilers. However, the existing conventional wall-hung boilers only utilize the heat of the combustion chamber once, and the high-temperature flue gas generated by combustion carries a large amount of heat that is not fully utilized and is discharged. Such wall-hung boilers have low energy utilization efficiency, high losses, high exhaust gas emissions, and large pollution. Therefore, wall-hung boilers with waste heat recovery functions have also emerged on the market.

Combining its specification and drawings, its scheme includes a gas inlet pipe, a proportional valve, a burner, a heat exchanger, and a blower. A heat exchanger is provided above the burner, and a blower is provided above the heat exchanger. The heat exchanger includes a heat exchanger housing, a shell-side inlet pipe, a shell-side outlet pipe, a water inlet, a water outlet, and multiple heat exchange tubes. However, if the heat exchanger housing is integrally formed, it will lead to poor internal processing accuracy, thus affecting the yield rate during mass production. Moreover, it is particularly difficult to add a structure to one end face inside the heat exchanger housing. Summary of the Invention

Detailed implementation manners

[0023] The present utility model will be further described below in conjunction with the embodiments shown in the drawings:

[0024] As Figures 1 to 2As shown, in the first embodiment of the present utility model, a housing for the water circuit and air circuit inside a wall-mounted boiler includes a support housing main body 1 that allows gas to pass through. A water circuit circulation component 2 is provided inside the support housing main body 1. The support housing main body 1 can be split into several housing parts, and the several housing parts are connected by welding or secondarily connected by encapsulation. Specifically, the support housing main body 1 includes a first air circuit housing 11, a second air circuit housing 12, and a water circuit housing 13. The first air circuit housing 11, the second air circuit housing 12, and the water circuit housing 13 are connected by welding or secondarily connected by encapsulation. The water circuit housing 13 includes a water circuit main housing 134 and a water circuit housing side plate 135, and the water circuit main housing 134 and the water circuit housing side plate 135 are also connected by welding or secondarily connected by encapsulation. One end of the first air circuit housing 11 is provided with a circular air guide port 111, and the other end of the first air circuit housing 11 is adapted to one end of the water circuit housing 13. One end of the second air circuit housing 12 is provided with a rectangular air guide port 121, and the other end of the second air circuit housing 12 is adapted to the other end of the water circuit housing 13. A number of first fixing seat bosses 131 are provided on one side of the water circuit housing 13. A first water inlet 132 and a first water outlet 133 are provided on the other side of the water circuit housing 13. The ends of the first water inlet 132 and the first water outlet 133 are both connected to an external water circuit pipeline. It should be noted that the materials of the first air circuit housing 11, the second air circuit housing 12, and the water circuit housing 13 are plastic materials. The secondary connection by encapsulation can complete the integration of multiple components at one time, reducing subsequent assembly steps, shortening the production cycle, helping to reduce waste and lower the defective rate. Moreover, the combination of encapsulation and the base material is completed simultaneously during the injection molding process, avoiding additional bonding or welding steps, reducing the assembly cost, and also reducing the need to use additional adhesives or other connection materials. The aforementioned welding method is specifically hot plate welding. Selecting hot plate welding has advantages in forming the entire support housing main body 1 because hot plate welding can be applied to workpieces of different sizes without area limitations and can be applied to any welding surface without special requirements. The welding strength is high: the welding surface can allow plastic margin compensation to ensure the welding strength; the flexibility is high: the welding program can be adjusted according to the requirements of various materials to meet different production needs; the equipment cost is low: the cost of hot plate welding equipment is relatively low, suitable for cost-sensitive production environments; the operation is simple: hot plate welding supports manual operation, making the operation process more flexible and simple.

[0025] As Figures 3 to 4 shown, in the second embodiment of the present utility model, the only difference from the first embodiment is that the circular air guide port 111 at the end of the first air circuit housing 11 is split into individual parts, and the circular air guide port 111 and the first air circuit housing 11 are also connected by hot plate welding or secondarily connected by encapsulation.

[0026] As Figures 5 to 6 shown, the water circulation component inside the first embodiment and the second embodiment of the present utility model, the water circulation component 2 includes a water guiding tank 21 and a honeycomb panel 22. The surface of the water guiding tank 21 is provided with a second water inlet 211, a second water outlet 212 and a plurality of rectangular through holes 213. The honeycomb panel 22 covers the entire water guiding tank 21. One end of the honeycomb panel 22 is provided with a plurality of second fixing bosses 221 adapted to the inside of the first fixing seat boss 131. The other end of the honeycomb panel 22 is provided with a third water inlet 222 and a third water outlet 223 respectively adapted to the second water inlet 211 and the second water outlet 212. After such a setting, the water circuits of the wall-mounted boiler are respectively connected to the ends of the first water inlet 132 and the first water outlet 133. Water flows into the inside of the water guiding tank 21 from the first water inlet 132. The wind generated by the wall-mounted boiler will flow into the inside of the water circuit housing 13 after passing through the first air path housing 11 or the second air path housing 12. The honeycomb panel 22 warms the water guiding tank 21, and the warmed water is then discharged through the second water outlet 212.

[0027] Working principle and usage method of the present utility model:

[0028] During the processing, the support shell main body 1 can be split into the first air path housing 11, the second air path housing 12, the water circuit main housing 134 and the water circuit housing side plate 135, or the circular air guide opening 111 at the end of the first air path housing 11 can be split into individual parts. After such splitting, the factory can adjust the internal structure of each part according to requirements. Compared with the integrally formed support shell main body 1, the accuracy of each part after processing is higher after splitting, and it can also be adjusted according to requirements.

[0029] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
