[0044] Figure 1 and Figure 2 Some preferred embodiments of the air source heat pump of the utility model are shown. The air source heat pump can be a trigeneration or digeneration device. In some embodiments, the air source heat pump can be an outdoor unit. The air source heat pump has the advantages of strong installation stability and overall beauty.

[0045] like Figures 1 to 6 As shown, the air source heat pump may include a housing 1 and a heat pump system component 2, wherein the housing 1 may be used to accommodate the heat pump system component 2. The heat pump system component 2 may be a water tank, an outdoor heat exchanger, a compressor, a hot water jacket heat exchanger and other components, which may be connected by pipelines to realize functions such as cooling, heating, and / or hot water production.

[0046] In some embodiments, the housing 1 may include a chassis 11, a top cover 12, and a face frame assembly 13. In some embodiments, the chassis 11 and the top cover 12 may be arranged relative to each other. The face frame assembly 13 may be arranged between the chassis 11 and the top cover 12. The face frame assembly 13 may be connected and fixed to the chassis 11 and the top cover 12 by setting a screw assembly. In some embodiments, the housing 1 may also include a side panel 14, a protective net 15, etc. The side panel 14 may be arranged between the chassis 11 and the top cover 12 and located on one side of the chassis 11 and the top cover 12. The protective net 15 is arranged between the chassis 11 and the top cover 12 and is arranged relative to part of the face frame assembly 13. The chassis 11, the top cover 12, the face frame assembly 13, the side panel 14, and the protective net 15 may define a receiving cavity for receiving the heat pump system components 2.

[0047] like Figure 6 As shown, in some embodiments, the length direction of the box body 1 is the first direction, that is, the first direction is the X direction, the width direction of the box body 1 is the second direction, that is, the second direction is the Y direction, and the first direction is perpendicular to the second direction.

[0048] The accommodating cavity can be divided into a first cavity and a second cavity arranged side by side in a first direction, wherein the first cavity can be used to accommodate a water tank, a compressor, a shell and tube heat exchanger and other system components, wherein the water tank can be vertically arranged in the first cavity, and the water tank may include an inner tank and an insulation structure wrapped around the outer periphery of the inner tank.

[0049] When the air source heat pump is running and in partial heat recovery or full heat recovery mode, the refrigerant coming out of the compressor will exchange heat with water in the shell and tube heat exchanger to prepare hot water. The prepared hot water will enter the domestic hot water tank. When the user needs hot water, the hot water in the domestic hot water tank can be transported to the corresponding equipment.

[0050] The second cavity can be used to accommodate an outdoor heat exchanger and a water receiving pan, and the outdoor heat exchanger may include a fan and a fin heat exchanger.

[0051] When the air source heat pump is running, the fan runs and draws outside air and the fin heat exchanger for heat exchange, so that the refrigerant inside the fin heat exchanger absorbs the heat of the outside air.

Of course, it is understandable that in other embodiments, the wind guide rings 1315 may not be limited to two.

[0060] In some embodiments, a first through hole 1316 may be provided on the first extension portion 1313 . The first through hole 1316 may be provided near an end of the first extension portion 1313 , and may be used for a screw to pass through.

[0061] like Figures 9 and 10 As shown, in some embodiments, the second panel 132 is disposed on the first extension portion 1313 and is clamped with the first extension portion 1313. The second panel 132 may include a second main body 1321 and a second extension portion 1322. The second main body 1321 may be partially disposed opposite to the protective net 15, and may be partially bent toward the protective net 15, and disposed opposite to the side panel 14. The second extension portion 1322 is disposed on a side of the second main body 1321 facing the first panel 131, and is bent toward the middle partition 133.

[0062] Read also Figure 4 , Figure 6 and Figure 7 In some embodiments, the second extension portion 1322 may be disposed on the first extension portion 1313 and may be arranged in a stepped manner with the first extension portion 1313. The second panel 132 may be snap-fitted with the first panel 131. Specifically, the second extension portion 1322 may be snap-fitted with the first extension portion 1313. Further, a snap-fitting protrusion 1323 may be disposed on the second extension portion 1322, and the snap-fitting protrusion 1323 may be arranged in a one-to-one correspondence with the first snap-fitting groove 1314.

The connecting portion 1332 is arranged on two opposite sides of the partition portion 1331 in the width direction, and can be used to connect with the first panel 131 or the second panel 132. In some embodiments, the second panel 132 can be snapped with the connecting portion 133, specifically, a second snap-in groove 1333 can be arranged on the connecting portion 133, and the second snap-in groove 1333 is arranged one-to-one with the first snap-in groove 1314 and the snap-in convex portion 1323. The snap-in convex portion 1323 can pass through the first snap-in groove 1314 and snap-in into the second snap-in groove 1333, so that it can replace the screw fixation, simplify the installation process, and save the installation cost. In some embodiments, a second through hole 1334 may be provided on the connecting portion 1332 , and the second through hole 1334 may be provided corresponding to the first through hole 1316 , and may be threadedly connected with a screw.

[0064] like Fig.12 and Fig.13As shown, in some embodiments, the air guide plate 134 may include a substrate 1341 and a plurality of convex strips 1342 disposed on the substrate 1341. The convex strips 1342 may protrude toward the side of the substrate 1341 that is disposed opposite to the first panel 131. In some embodiments, the maximum thickness of the air guide plate 134 is less than or equal to the height difference between the first panel 131 and the second panel 132 in the second direction. Specifically, the sum of the thickness of the substrate 1341 and the height of the convex strips 1342 protruding in the second direction is less than or equal to the height difference between the first panel 131 and the second panel 132 in the second direction, thereby ensuring the overall flatness and aesthetics of the face frame assembly and preventing the air guide plate 134 from being damaged by friction during transportation. The convex strips 1342 may protrude toward the side of the substrate 1341 that is disposed opposite to the first panel 131. In some embodiments, a plurality of convex strips 1342 may be arranged on the air guide port 1312 in a direction away from the first panel 131, which may play a role in guiding wind and silencing, thereby improving heat exchange efficiency while reducing noise. The wind deflector 134 is provided with a third extension 1343, which is formed on the substrate 1341 and can extend toward the first panel 131. The third extension 1343 can be connected and fixed to the first panel 131 by setting a connection structure. In some embodiments, it can be connected to the first panel 131 by setting a screw assembly. In some embodiments, a vent 1344 can be provided on the wind deflector 134, and the vent 1344 can be arranged in a one-to-one correspondence with the wind guide port 1312 and communicate with the wind guide port 1312. A plurality of convex strips 1342 can be arranged on the vent 1344. In some embodiments, a third through hole 1345 can be provided on the third extension 1343, and the third through hole 1345 is arranged corresponding to the first through hole 1316, and can be used for screws to pass through.

The first side wall 1351 may be parallel to the third extension portion 1343 and spaced apart. A fourth through hole 1352 may be disposed on the first side wall 1351, and the fourth through hole 1352 may be disposed corresponding to the third through hole 1345, the first through hole 1316, and the second through hole 1334, and the screw may be screwed through the fourth through hole 1352, the third through hole 1345, the first through hole 1316, and the second through hole 1334 in sequence. The two second side walls 1353 may extend toward the third extending portion 1343 and be bent with the first side wall 1351 .

[0066] For example Figure 4 As shown, in some embodiments, a groove 130 may be formed between the protrusion 1342 and the second panel 132, and the decorative piece 135 may be embedded and installed in the groove 130, and its thickness may be equal to or less than the depth of the groove 130, so that the decorative piece 135 can be flush with the first panel 131 and the air guide plate 134, or be set lower than the first panel 131 and the air guide plate 134, thereby preventing the decorative piece 135 and the air guide plate 134 from being damaged by friction during transportation.

[0067] In some embodiments, the snap-fitting protrusion 1323 of the second panel 132 can also be snap-fitted with the decorative member 135 for fixing, which can save the screw fixing process and achieve an aesthetic effect. In some embodiments, the second side wall 1353 of the decorative member 135 can also be fixed with the third extension portion 1343 by setting a snap-fitting structure, thereby saving the screw fixing process and simplifying the installation process.
