The first heat exchanging part 300 may be a heat pump heat exchanging part, and the first joint 301 and the second joint 302 are used for communicating with an external cold source/heat source. The cold/heat source may include any one of the following: air source heat pump, ground source heat pump, water source heat pump. In the embodiments of the present specification, the heat sink/source is mainly exemplified by an air source heat pump.

In the embodiment provided in the present specification, the wall-hanging stove integrates at least the combustion heat exchanging portion 200 and the first heat exchanging portion 300, so that the size of the whole stove can be reduced, the pipelines can be shortened, the cost can be reduced, the installation can be simplified, the reliability of the product can be improved, and the convenience of maintenance and repair in the using process of the product can be improved.

In the present embodiment, the combustion heat exchanging part 200 and the living water heat exchanging part 250 constitute core components of a conventional wall-hanging stove. For a conventional wall-mounted boiler, the combustion heat exchange part 200 and the domestic water heat exchange part 250 are generally installed in a single housing, and then different joints are led out from the housing to connect heating inlet water and return water and domestic water inlet water and return water. In the wall-hanging stove according to the embodiment of the present invention, the combustion heat exchanging portion 200, the first heat exchanging portion 300, and the domestic water heat exchanging portion 250 are rearranged, so that the limited installation space can be more efficiently used.

Further, the living water heat exchanging part 250 may be located at a lower portion of the combustion heat exchanging part 200 and/or the first heat exchanging part 300 in the height direction Z.

The domestic water heat exchanger 250 may be located below the combustion heat exchanger 200, the domestic water heat exchanger 250 may be located below the first heat exchanger 300, or the domestic water heat exchanger 250 may be located below both the combustion heat exchanger 200 and the domestic water heat exchanger 250. The specific position of the domestic water heat exchanging part 250 may be reasonably arranged according to the distribution of the installation space left below after the combustion heat exchanging part 200 and the first heat exchanging part 300 are arranged side by side.

As shown in fig. 2, 3 or 4, when the wall-hanging stove is applied to a heat exchange system, the first heat exchanging part 300 can be communicated with the heat exchange end 400 through a first water outlet pipe 310 and a first water return pipe 320, and the combustion heat exchanging part 200 is communicated with the water path connection module through a second water outlet pipe 201 and a second water return pipe 202.

The first water outlet pipe 310 may be configured to guide a fluid with a relatively high temperature (in the following embodiments, the fluid is mainly described by taking water as an example) flowing out from the first heat exchanging part 300 to the heat exchanging end 400, and after the heat exchanging end 400 performs heat dissipation and temperature reduction, the high-temperature water flows back to the first heat exchanging part 300 through the first water return pipe 320 to perform heat exchange and temperature increase, and then the above process is repeated.

The second water outlet pipe 201 may partially guide the higher temperature fluid (mainly, water is taken as an example, in the following embodiment, the temperature of the fluid in the second water outlet pipe 201 is generally higher than that of the first water outlet pipe 310) flowing out from the combustion heat exchanging part 200 to the water path connection module, then the higher temperature water may be mixed with the water flowing out from the water path connection module and the first water outlet pipe 310 to raise the temperature of the water flowing out from the first water outlet pipe 310, then part of the mixed water returns to the combustion heat exchanging part 200 through the second water return pipe 202 to perform heat exchange and temperature rise, and the other part of the mixed water is supplied to the heat exchanging end 400 through the first water outlet pipe 310, exchanges heat with the heat exchanging end 400, and then returns to the first heat exchanging part 300 through the first water return pipe 320.

Wherein, a first circulating pump 305 for providing power for circulating water can be arranged on the first water outlet pipe 310 or the first water return pipe 320.

For example, a certain installation space is formed between the first heat exchanging part 300 and the combustion heat exchanger, and the first circulation pump 305 and corresponding pipes can be installed in the space using the installation space to achieve a high utilization of the space in the casing 110.

The second water outlet pipe 201 or the second water return pipe 202 may also be provided with a second circulation pump 203 for providing power for circulating the water. The above heat exchange process is repeated by circulating the water flow in the pipes of the heat exchange system by the first circulation pump 305 and the second circulation pump 203.

In one embodiment, the waterway connection module may include any one or a combination of the following: coupling tank 351, a three-way structure.

In this embodiment, the waterway connection module may include various forms of coupling tanks 351, a tee structure, etc., or a combination thereof. The following description will be developed in conjunction with the accompanying drawings.

As shown in fig. 2, in one embodiment, the combustion heat exchanger 200 connects the second water outlet pipe 201 to the first water outlet pipe 310 through a first three-way structure 352, the combustion heat exchanger 200 connects the second water return pipe 202 to the first water outlet pipe 310 through a second three-way structure 353, and the first three-way structure 352 is upstream of the second three-way structure 353 in the water flow direction along the first water outlet pipe 310; alternatively, the first tee structure 352 is downstream of the second tee structure 353.

In this embodiment, the waterway connection module may include two tee structures, namely a first tee structure 352 and a second tee structure 353. The combustion heat exchanging part 200 may connect the second water outlet pipe 201 and the second water return pipe 202 to the first water outlet pipe 310 through the first three-way structure 352 and the second three-way structure 353.

Generally, the temperature of the water heated by the combustion heat exchanging part 200 is high, and when the high-temperature water enters the first water outlet pipe 310 through the second water outlet pipe 201, the high-temperature water can be mixed with the water flowing out of the first water outlet pipe 310, so as to raise the temperature of the water flowing out from the first water outlet pipe 310 to the heat exchanging end 400.

The first tee structure 352 may be located upstream of the second tee structure 353, and at this time, the water flowing out from the first water outlet pipe 310 and the water flowing out from the second water outlet pipe 201 flow in the same direction. In addition, the first three-way structure 352 may be located downstream of the second three-way structure 353, and at this time, the water flowing out from the first water outlet pipe 310 and the water flowing out from the second water outlet pipe 201 flow in opposite directions.

Further, the ratio of the length of the pipeline between the first tee structure 352 and the second tee structure 353 to the diameter of the pipeline is not less than 4.

In this embodiment, when the ratio of the length L of the pipeline between the first three-way structure 352 and the second three-way structure 353 to the diameter is greater than or equal to 4, the water flowing out of the second water outlet pipe 201 can be fully mixed with the water flowing out of the first water outlet pipe 310, so as to reliably ensure that the two fluids with different temperatures can fully exchange heat.

In another embodiment, as shown in fig. 3, the waterway connection module includes a coupling tank 351, the coupling tank 351 is provided with a first end and a second end opposite to each other, the combustion heat exchanging part 200 is communicated with the first end of the coupling tank 351 through the second water outlet pipe 201, and the combustion heat exchanging part 200 is communicated with the second end through the second water return pipe 202.

In this embodiment, the waterway connection module may include a coupling tank 351. The coupling tank 351 may be a hollow tank body, which may include opposite first and second ends along a lengthwise extension direction. The combustion heat exchanging part 200 may be connected to a first end of the coupling tank 351 through a second water outlet pipe 201, and connected to a second end of the coupling tank through a second water return pipe 202.

Specifically, the coupling tank 351 may be disposed in the first water outlet pipe 310, and of course, the coupling tank 351 may be disposed at other positions, for example, in the first water return pipe 320, or between the first water outlet pipe 310 and the first water return pipe 320. Taking the example that the coupling tank 351 is disposed in the first water outlet pipe 310, the water flowing out of the first water outlet pipe 310 enters the coupling tank 351 from one end of the coupling tank 351, is mixed with the water provided by the second water outlet pipe 201, and then a part of the mixed water flows out of the other end of the coupling tank 351 and is supplied to the heat exchange terminal 400.

In one embodiment, an isolated cavity 103 is further disposed in the housing 110, and the combustion heat exchanging part 200 is located in the isolated cavity 103.

In the present embodiment, an isolation chamber 103 for isolating the combustion heat exchanging part 200 may be provided in the case 110. The size of the isolation chamber 103 may be matched according to the size and configuration of the combustion heat exchanging part 200, and the specific application is not limited thereto. The isolation cavity 103 can be made of high-temperature-resistant sheet metal parts.

The isolation cavity 103 may be a sealed cavity or a non-sealed cavity. When the insulating cavity 103 is a non-sealed cavity, the insulating cavity 103 can be used at least for insulating the combustion heat exchanging part 200, so as to prevent high-temperature radiation from having an adverse effect on other components in the housing 110, particularly on temperature-sensitive electronic components, when the combustion heat exchanging part 200 is in operation.

When the isolation chamber 103 is a sealed chamber, it may be used to insulate the combustion heat exchange portion 200, and may also improve the safety of the product in use for some condensing furnace type combustion heat exchange portions 200. Specifically, the combustion heat exchanging part 200 may include any one of the following: coil heat exchanger, parallel tube heat exchanger.

When the combustion heat exchanging part 200 is in the form of the coil heat exchanger, the parallel tube heat exchanger, or the like, since the first heat exchanging part 300 and the combustion heat exchanging part 200 are disposed in the same casing 110, in case of leakage of the refrigerant in the first heat exchanging part 300, the refrigerant may be sucked into the combustion heat exchanging part 200, and further, safety accidents such as explosion may occur. In summary, in order to improve the reliability and safety of the product during use, the isolation cavity 103 may be a sealed cavity to prevent the refrigerant in the first heat exchanging part 300 from entering the combustion heat exchanging part 200 when leakage occurs, which may cause safety accidents.

In one embodiment, the combustion heat exchanging portion 200 takes the form of a coil heat exchanger, the thickness direction of which extends along the width direction X.

In the present embodiment, when the combustion heat exchanging portion 200 employs a coil heat exchanger, the coil heat exchanger has opposite thickness directions. As shown in fig. 1, the outer profile of the coil heat exchanger along the thickness direction may be circular, or elliptical, or other regular or irregular shapes, and the circular shape is taken as an example for illustration. When the diameter of the coil heat exchanger is larger than the thickness of the coil heat exchanger, in order to be able to mount the combustion heat exchanging portion 200 and the first heat exchanging portion 300, which are arranged side by side, in the same housing 110 without increasing the size of the housing 110 as much as possible, the coil heat exchanger may be rotated by 90 ° with respect to a conventional mounting manner, i.e., such that the thickness direction of the coil heat exchanger extends in the width direction X of the housing 110.

When the thickness of the coil heat exchanger is larger than the outer dimension (e.g., diameter), the coil heat exchanger can be flexibly set according to the dimension of the coil heat exchanger and the dimension of the first heat exchanger, and the overall dimension of the housing 110 is ensured to be as small as possible (particularly, the height dimension and the width dimension of the housing 110 are not increased).

In one embodiment, the first heat exchanging part 300 includes a plate heat exchanger including a first flow passage 330 and a second flow passage 340 which are separated from each other. The first joint 301 and the second joint 302 communicate with the second flow path 340. The housing 110 is provided with a third joint 303 communicated with the first flow passage 330 and used for providing heating outlet water and a fourth joint 304 for receiving heating return water.

In this embodiment, the first heat exchanging part 300 may include a plate heat exchanger, and the first flow channel 330 and the second flow channel 340, which are separated from each other, may be provided inside the plate heat exchanger. In the case that the first heat exchanging part 300 is a heat pump heat exchanging part, the first flow channel 330 is used for flowing heating water, and the second flow channel 340 is used for flowing cooling/heating medium. The casing 110 is provided with a first joint 301 and a second joint 302 for communicating the second flow channel 340 with the heat pump outdoor unit 600.

Referring to fig. 1 and 4 in combination, in one specific embodiment, the plate heat exchanger extends lengthwise along a length direction, and the plate heat exchanger has a first end and a second end opposite to each other along the length direction, and the first end is higher than the second end. The plate heat exchanger has a first port 311 for receiving an external medium, a second port 312 for letting out the external medium; a third port 313 for providing heating outlet water and a fourth port 314 for receiving heating return water, wherein the first port 311 and the third port 313 are arranged near the first end, and the second port 312 and the fourth port 314 are arranged near the second end.

When the plate heat exchanger is mounted, the longitudinal direction of the plate heat exchanger may be aligned with the height direction Z of the housing 110, so that a space saved in the width direction X may be saved by rotating the combustion heat exchanging part 200 by 90 degrees. The first end of the plate heat exchanger is an upper end, and the second end is a lower end.

The first port 311 for receiving the external medium and the third port 313 for providing heating water can be arranged near the upper end, the second port 312 for flowing the external medium and the fourth port 314 for receiving heating water can be arranged near the lower end, so that when the heat pump is in a heating state, the heating water flows from bottom to top, the refrigerant flows from top to bottom, convection is formed, sufficient heat exchange is facilitated, and meanwhile, the gaseous refrigerant can be liquefied along the refrigerant flowing direction in the process of condensing to form liquid and flows back to the heat pump outdoor unit 600 again.

Referring to fig. 1 and 5, further, the housing 110 has a top wall 101 and a bottom wall 102 opposite to each other, the domestic water heat exchanging part 250 is provided with a fifth joint 251 and a sixth joint 252, the domestic water inlet joint and the domestic water outlet joint are arranged on the bottom wall 102, and the first joint 301, the second joint 302, the third joint 303 and the fourth joint 304 are arranged on the top wall 101.

In this embodiment, the domestic water heat exchanging part 250 may be in the form of a domestic water plate, and the domestic water plate is provided with a fifth joint 251 and a sixth joint 252 for respectively serving as a domestic water inlet and a domestic water outlet. Since the domestic water heat exchanging part 250 is disposed near the bottom wall 102 of the housing 110, the fifth joint 251 and the sixth joint 252 may be disposed on the bottom wall 102, so that piping in the housing 110 may be reduced. Further, the first and third joints 301 and 303, and the second and fourth joints 302 and 304 may be provided on the top wall 101.

For example, as shown in fig. 4, the relief valve 502 may be connected to the second return pipe 202. Since the second water return pipe 202 is connected to the first water outlet pipe 310 and the second water outlet pipe 201 via a water path connection module (e.g. a coupling tank 351), when the pressure in the whole system is unstable, for example, suddenly increases to exceed the set value of the pressure relief valve 502, the pressure relief valve 502 opens, and the system is depressurized.

In a specific embodiment, a water replenishing valve 503 is connected to the second water outlet pipe 201 or the second water return pipe 202.

In the present embodiment, since the heating water of the entire system is communicated with each other, the water replenishment valve 503 of the first heat exchanging part 300 may be omitted and only the water replenishment valve 503 of the combustion heat exchanging part 200 may be left. The water replenishing valve 503 may be connected to the water inlet side of the domestic water heat exchanging part 250. In addition, the water replenishment valve 503 may be disposed between the domestic water heat exchange part 250 and the heating water returning water (e.g., the second water returning pipe 202).

In a specific embodiment, the wall-hanging stove may further include a water receiving tray (not shown) positioned below the combustion heat exchanging part 200 and the first heat exchanging part 300.

In this embodiment, the wall-hanging stove may include a drain pan, which may be disposed below the combustion heat exchanging part 200 and the first heat exchanging part 300 to collect condensed water generated by the combustion heat exchanging part and the first heat exchanging part during operation.

It should be noted that: for the case that the isolation cavity 103 is disposed outside the combustion heat exchanging portion 200, a diversion hole may be formed at the bottom of the isolation cavity 103, and the diversion hole directs the condensed water to a water pan, and at this time, the water pan may not be completely located below the combustion heat exchanging portion 200, and may even be staggered from the combustion heat exchanging portion 200.

In a specific embodiment, the wall-hanging stove may further include a three-way structure for combining the fluid discharged from the pressure relief valve 502 and the fluid discharged from the water receiving tray and guiding the combined fluid to the same discharge port.

In this embodiment, in order to shorten the pipeline in the wall-hanging furnace and reduce the number of holes in the housing 110, the fluid discharged from the pressure release valve 502 and the fluid discharged from the water pan may be first combined by using a three-way structure, and then the combined fluid may be discharged to the discharge port through the same pipeline.
