Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air source heat pump. Background Art

[0002] As an energy-saving and environmentally friendly energy device, air source heat pump can be connected to hot water pipes through pipes, and is the best solution to solve the problem of large-scale centralized heating. Air source heat pump includes fin heat exchanger, shell and tube heat exchanger and refrigerant circuit. Fin heat exchanger and shell and tube heat exchanger are connected in series to the refrigerant circuit. The refrigerant circulates between fin heat exchanger and shell and tube heat exchanger through the refrigerant circuit to realize energy transmission, and then heats or cools the water in the shell and tube heat exchanger, and transmits it to the room through pipes to adjust the indoor temperature.

[0003] In the related art, in order to facilitate users to use the air source heat pump, the shell and tube heat exchanger is generally installed in the shell of the outdoor unit, and the water inlet pipe and the water outlet pipe of the shell and tube heat exchanger need to be connected to the shell, so that the water inlet pipe can be connected to the water pipe that provides the water source, and the water outlet pipe can be connected to the water-using equipment.

[0004] However, since the water inlet pipe and the water outlet pipe of the shell and tube heat exchanger have a certain length, when the water inlet pipe and the water outlet pipe of the shell and tube heat exchanger are connected to the shell, the water inlet pipe and the water outlet pipe will shake and deviate, making it difficult to align the water inlet pipe and the water outlet pipe with the position on the shell for connecting the water inlet pipe and the water outlet pipe, thereby making it inconvenient to install the water inlet pipe and the water outlet pipe. Utility Model Content

[0005] An embodiment of the utility model provides an air source heat pump, which is used to solve the problem of inconvenient installation of a water inlet pipe and a water outlet pipe during the installation of the air source heat pump.

[0006] To achieve the above-mentioned object, in the first aspect of the present application, an air source heat pump is provided, comprising a housing, a first heat exchanger, a cover plate and a positioning member. The housing is formed with a receiving cavity with an opening on one side. The first heat exchanger is arranged in the receiving cavity and connected to the housing. The first heat exchanger comprises an inlet pipe and an outlet pipe, and the outlet end of the inlet pipe is connected to the inlet end of the outlet pipe. The inlet pipe is used to connect an external water source so that water from the water source enters the first heat exchanger through the inlet pipe and is heat exchanged by the first heat exchanger, and the outlet pipe is used to connect a water-using device. The cover plate is connected to the housing and is located at the opening of the receiving cavity to block the opening of the receiving cavity. A mounting hole is provided on the cover plate. The positioning member is arranged in the receiving cavity and connected to the housing. The positioning member comprises a baffle plate, which is connected to the cover plate and is located at the mounting hole. The baffle plate is formed with a first positioning hole and a second positioning hole, the inlet end of the inlet pipe passes through the first positioning hole and extends into the mounting hole, and the outlet end of the outlet pipe passes through the second positioning hole and extends into the mounting hole.

[0007] By providing the opening, the first heat exchanger can be more conveniently fixed on the partition, and then the positioning member can be installed on the shell, and the water inlet pipe passes through the first positioning hole, and the water outlet pipe passes through the second positioning hole, so that the water inlet pipe and the water outlet pipe can be positioned by the baffle on the positioning member. After the water inlet pipe and the water outlet pipe are positioned by the baffle, the cover plate can be connected to the shell, and the cover plate and the baffle are connected so that the baffle is located at the installation hole, so that the water inlet pipe and the water outlet pipe extend into the installation hole.

[0008] In this way, through the positioning effect of the first positioning hole on the baffle plate on the water inlet pipe and the positioning effect of the second positioning hole on the water outlet pipe, the water inlet pipe and the water outlet pipe can be accurately extended into the installation hole. In this way, when connecting the cover plate and the shell, it is only necessary to connect the cover plate and the baffle plate so that the cover plate can be accurately installed on the shell, which can facilitate the installation of the water inlet pipe and the water outlet pipe.

[0009] In some embodiments of the present application, the positioning member further includes a bracket, the bracket is connected to the shell, a third positioning hole is formed on the bracket, and a positioning fold is formed on the baffle, and the positioning fold extends into the third positioning hole.

[0010] In this way, when positioning the water inlet pipe and the water outlet pipe of the first heat exchanger, it is only necessary to accurately connect the bracket to the required position on the shell, and the water inlet pipe and the water outlet pipe can be positioned through the baffle. This can facilitate the setting of the baffle and the positioning of the water inlet pipe and the water outlet pipe.

[0011] In some embodiments of the present application, the accommodating cavity has a bottom wall, and the wall surface of the bottom wall is perpendicular to the plane where the opening of the accommodating cavity is located. The bracket includes a connecting portion and a supporting portion, and the connecting portion is connected to the bottom wall. The third positioning hole is opened in the connecting portion. The supporting portion is connected to the connecting portion, and the baffle is arranged on a side of the supporting portion away from the bottom wall and in contact with the supporting portion.

[0012] In this way, after the positioning folded edge on the baffle is extended into the third mounting hole on the connecting part and the baffle and the connecting part are abutted, the supporting part can contact the side of the baffle close to the bottom wall of the accommodating cavity, thereby providing support for the baffle, so that the baffle can be more stably connected to the bracket, thereby ensuring the positioning effect of the first positioning hole on the baffle on the water inlet pipe and the positioning effect of the second positioning hole on the water outlet pipe.

[0013] In some embodiments of the present application, the housing further comprises a positioning plate, which is arranged on the bottom wall. The bracket further comprises a positioning portion, which is connected to the connecting portion and contacts the positioning plate.

[0014] In this way, when connecting the bracket to the bottom wall of the accommodating cavity, the positioning portion and the positioning plate on the bottom wall can be abutted first, so that the positioning plate limits the positioning portion, and then the bracket is moved along the positioning plate and moved to the required position on the bottom wall, and then the bracket and the bottom wall of the accommodating cavity are connected, so that the bracket is accurately connected to the bottom wall of the accommodating cavity. In this way, the bracket can be quickly moved to the required position on the bottom wall of the accommodating cavity to facilitate the connection between the bracket and the bottom wall of the accommodating cavity.

[0015] In some embodiments of the present application, the air heat source pump further includes a partition and a connecting plate. The partition is disposed in the accommodating cavity and connected to the housing. A first connecting hole and a second connecting hole are formed on the connecting plate, and at least one of the first connecting hole and the second connecting hole extends along a first direction, and the first direction is perpendicular to the axial direction of the first connecting hole and perpendicular to the axial direction of the second connecting hole. One of the first connecting hole and the second connecting hole is connected to the partition, and the other of the first connecting hole and the second connecting hole is connected to the first heat exchanger.

[0016] In this way, the first heat exchanger is connected to the connecting plate, and the connecting plate is connected to the partition, so that the first heat exchanger and the partition are indirectly connected together, and then the first heat exchanger is indirectly connected to the shell, so that the first heat exchanger is stably arranged in the accommodating cavity.

[0017] In some embodiments of the present application, the air heat source pump also includes a compressor, and the first heat exchanger is disposed above the compressor.

[0018] Through the above-mentioned arrangement, the first heat exchanger and the compressor are arranged at intervals in the vertical direction. Compared with the first heat exchanger and the compressor being arranged at intervals in the horizontal direction, the space of the air source heat pump in the vertical direction can be reasonably utilized to reduce the space occupied by the first heat exchanger and the compressor in the horizontal direction. In this way, the space occupied by the air source heat pump in the horizontal direction can be reduced, so that more air source heat pumps can be arranged in a certain space, thereby improving the utilization rate of the space for placing the air source heat pump.

[0019] In some embodiments of the present application, the air source heat pump further includes a first fastener, through which the baffle is connected to the cover plate. And / or, the air source heat pump further includes a second fastener, through which the baffle is connected to the bracket.

[0020] In this way, since the baffle is connected to the cover plate through the first fastener, and the baffle is connected to the bracket through the second fastener, the baffle, the bracket and the cover plate can be connected to each other, which can improve the structural stability between the bracket, the baffle and the cover plate, thereby ensuring the positioning effect of the baffle on the water inlet pipe and the water outlet pipe.

[0021] In some embodiments of the present application, the housing includes a base, a top plate and a side plate, the top plate is arranged above the base, and the side plate is connected between the base and the top plate. The air source heat pump also includes a seal, which is sealed and connected to both the top plate and the side plate.

[0022] In this way, when rainwater flows to the gap between the top plate and the side plate, since the seal is sealed and connected to both the top plate and the side plate, the seal can prevent rainwater from entering between the partition plate and the cover plate from the gap between the top plate and the side plate, thereby preventing the components between the cover plate and the partition plate from being affected by rainwater, thereby ensuring the normal function of the components between the cover plate and the partition plate and ensuring the normal use of the air source heat pump.

[0023] In some embodiments of the present application, the sealing member includes a fixing member, a first sealing gasket and a second sealing gasket. The fixing member is disposed on one side of the side plate. The first sealing gasket is connected to the upper side of the fixing member. The second sealing gasket is connected to the upper side of the fixing member and is located on the side of the first sealing gasket away from the side plate. A portion of the top plate is located on the upper side of the first sealing gasket and abuts against the first sealing gasket, and a bending portion is formed at one end of the side plate away from the base, the bending portion is bent along the direction of the side plate pointing to the fixing member, and the bending portion is located above the second sealing gasket and abuts against the second sealing gasket.

[0024] Through the above arrangement, the fixing member can provide support for the first gasket and the second gasket, so that the first gasket can seal the fixing member and the top plate, thereby preventing rainwater from flowing into the accommodating cavity from between the fixing member and the top plate, and the second gasket can seal the fixing member and the side plate, thereby preventing rainwater from flowing into the accommodating cavity from between the fixing member and the side plate. In this way, the fixing member, the first gasket and the second gasket can seal the gap between the side plate and the top plate, thereby preventing the components between the cover plate and the partition plate from being affected by rainwater, thereby ensuring the normal use of the air source heat pump.

[0025] In a second aspect of the present application, an air source heat pump is provided, comprising a shell, a first heat exchanger and a positioning member. The shell is formed with a accommodating cavity. The first heat exchanger is arranged in the accommodating cavity and connected to the shell. The first heat exchanger comprises a water inlet pipe and a water outlet pipe, and the water outlet end of the water inlet pipe is connected to the water inlet end of the water outlet pipe. The water inlet pipe is used for an external water source so that water from the water source enters the first heat exchanger through the water inlet pipe and is heat exchanged by the first heat exchanger, and the water outlet pipe is used for connecting a water-using device.

[0053] As an energy-saving and environmentally friendly energy device, air source heat pump can be connected to hot water pipes through pipes, which is the best solution to solve the problem of large-scale centralized heating. Air source heat pump includes shell and tube heat exchanger and fin heat exchanger, through the cooperation of shell and tube heat exchanger and fin heat exchanger, the indoor temperature is adjusted.

[0054] In the related art, in order to facilitate users to use the air source heat pump, the shell and tube heat exchanger is generally installed in the outdoor unit where the fin heat exchanger is located, so as to facilitate users to install and maintain the air source heat pump and reduce the footprint of the equipment.

[0055] Based on this, the present application provides an air source heat pump, such as Figure 1 As shown, the air source heat pump 01 includes a housing 1 and a first heat exchanger 2, and the housing 1 is formed with a receiving cavity 1A. Figure 1 , Figure 2As shown, the housing 1 includes a base 11, a top plate 12 and an outer shell, wherein the top plate 12 is spaced apart from the base 11 and is located above the base 11, and the plane where the top plate 12 is located is parallel to the plane where the base 11 is located. The outer shell is connected between the base 11 and the top plate 12, and extends around the arrangement direction of the base 11 and the top plate 12, and the outer shell, the top plate 12 and the base 11 together form a receiving chamber 1A.

[0056] The first heat exchanger 2 is disposed in the accommodating chamber 1A and connected to the housing 1. Specifically, Figure 1 , Figure 3 As shown, the air source heat pump 01 further includes a partition 3 and a connecting plate 4, the partition 3 is arranged in the accommodating cavity 1A and connected to the shell 1. Exemplarily, the partition 3 is fixed on the base 11, and the thickness direction of the partition 3 is perpendicular to the arrangement direction of the base 11 and the shell. Among them, the first heat exchanger 2 can be a shell and tube heat exchanger, a heat storage heat exchanger, etc.

[0057] The connecting plate 4 is formed with a first connecting hole 41 and a second connecting hole 42. At least one of the first connecting hole 41 and the second connecting hole 42 is formed along a first direction ( Figure 3 The first direction extends in an X direction (shown in FIG. 1 ), the first direction is perpendicular to the axial direction of the first connection hole 41, and is perpendicular to the axial direction of the second connection hole 42.

[0058] That is to say, the first connection hole 41 extends along the first direction, and the second connection hole 42 can be a circular hole or extend along the first direction; the second connection hole 42 extends along the first direction, and the first connection hole 41 can be a circular hole or extend along the first direction.

[0059] Exemplarily, the connecting plate 4 is a flat plate, and along the thickness direction of the connecting plate 4, one side of the connecting plate 4 contacts the partition 3, and the other side of the connecting plate 4 contacts the peripheral wall surface of the first heat exchanger 2, and the axial direction of the first connecting hole 41 and the axial direction of the second connecting hole 42 are consistent with the thickness direction of the connecting plate 4.

[0060] Exemplarily, the connecting plate 4 is an L-shaped plate, that is, it includes a first sub-connecting plate and a second sub-connecting plate, the thickness direction of the first sub-connecting plate is consistent with the thickness direction of the partition 3, and the thickness direction of the second sub-connecting plate is consistent with the vertical direction. The first connecting hole 41 is opened on the first sub-connecting plate, and the axial direction of the first connecting hole 41 is consistent with the thickness direction of the first sub-connecting plate, and the second connecting hole 42 is opened on the second sub-connecting plate, and the axial direction of the second connecting hole 42 is consistent with the thickness direction of the second sub-connecting plate. The first sub-connecting plate contacts the partition 3, and the second sub-connecting plate contacts the upper end surface of the first heat exchanger 2.

[0061] One of the first connection hole 41 and the second connection hole 42 is connected to the partition 3. For example, one of the first connection hole 41 and the second connection hole 42 can be connected to the partition 3 by a screw or a bolt.

[0062] The other one of the first connection hole 41 and the second connection hole 42 is connected to the first heat exchanger 2. For example, the other one of the first connection hole 41 and the second connection hole 42 can be connected to the first heat exchanger 2 by screws or bolts.

[0063] Exemplarily, the number of the connecting plates 4 may be one, two, three, four, etc.

[0064] In this way, by connecting the first heat exchanger 2 to the connecting plate 4 and the connecting plate 4 to the partition 3, the first heat exchanger 2 and the partition 3 are indirectly connected together, and then the first heat exchanger 2 is indirectly connected to the shell 1, so that the first heat exchanger 2 is stably arranged in the accommodating cavity 1A.

[0065] Exemplarily, the first connection hole 41 extends along the first direction, and the first connection hole 41 is connected to the partition 3, and the second connection hole 42 is a circular hole, and the second connection hole 42 is connected to the first heat exchanger 2. At this time, since the first connection hole 41 extends along the first direction, the first connection hole 41 has an adjustment space in the first direction, so that when the partition 3, the connecting plate 4 and the first heat exchanger 2 are connected together by fasteners, a fastener (such as a bolt, a screw, etc.) can be first passed through the second connection hole 42 and connected to the first heat exchanger 2, and then another fastener (such as a bolt, a screw, etc.) can be passed through the first connection hole 41, and the position of the other fastener in the first connection hole 41 can be adjusted along the first direction so that the other fastener is aligned with the connection hole on the partition 3, so that the other fastener can connect the partition 3 and the connecting plate 4, so that the connection between the first connection hole 41 and the partition 3 can be facilitated, and then the connection between the first heat exchanger 2 and the partition 3 can be facilitated.

[0066] In some examples, the partition 3 includes a first sub-partition and a second sub-partition, the thickness direction of the first sub-partition and the thickness direction of the second sub-partition are not parallel, and there are two connecting plates 4, one of which is connected between the first sub-partition and the first heat exchanger 2, and the other connecting plate 4 is connected between the second sub-partition and the first heat exchanger 2. In this way, the two connecting plates 4 can connect the first heat exchanger 2 and the partition 3 more stably, so that the first heat exchanger 2 is more stably arranged in the accommodating chamber 1A.

[0067] On the basis of the above, if Figure 4As shown, the first heat exchanger 2 includes an inlet pipe 21 and an outlet pipe 22, and the outlet end of the inlet pipe 21 is connected to the inlet end of the outlet pipe 22. The first heat exchanger 2 is a shell and tube heat exchanger. The inlet pipe 21 is used to connect to an external water source, so that water from the water source enters the first heat exchanger 2 through the inlet pipe 21 and is heat exchanged by the first heat exchanger 2, and the outlet pipe 22 is used to connect to water-using equipment.

[0068] Exemplarily, the water inlet pipe 21 and the water outlet pipe 22 are partially extended to the outside of the housing 1, so that the water inlet pipe 21 is connected to a water pipe providing a water source, and the water outlet pipe 22 is connected to a water pipe connected to a water-using device.

[0069] Exemplarily, the water pipe providing the water source and the water pipe connected to the water-using device both partially extend into the accommodating chamber 1A, so that the water inlet pipe 21 is connected to the water pipe providing the water source, and the water outlet pipe 22 is connected to the water pipe connected to the water-using device.

[0070] On the basis of the above, the air source heat pump 01 also includes a second heat exchanger and a refrigerant circuit, both of which are located in the accommodating cavity 1A. The second heat exchanger can be a fin heat exchanger, a plate heat exchanger, etc. The first heat exchanger 2 and the second heat exchanger are both connected in series to the refrigerant circuit. Refrigerant flows in the refrigerant circuit, and the refrigerant is used to transfer heat.

[0071] The air source heat pump 01 also includes a compressor 8 and a throttle valve, which are both connected in series to the refrigerant circuit. The throttle valve is used to adjust the flow rate of the refrigerant in the refrigerant circuit to adjust the heating and cooling effects of the first heat exchanger 2. The compressor 8 is used to compress the refrigerant in the refrigerant circuit and promote the refrigerant to circulate between the first heat exchanger 2 and the second heat exchanger to achieve heat transfer.

[0072] Specifically, when the air source heat pump 01 is in a cooling state, the compressor 8 will compress the refrigerant in the refrigerant circuit and push the refrigerant into the second heat exchanger (acting as a condenser). Through the cooling effect of the second heat exchanger, the heat in the refrigerant is dissipated into the air, thereby reducing the temperature of the refrigerant. When the low-temperature refrigerant continues to flow into the first heat exchanger 2 (acting as an evaporator), the low-temperature refrigerant will absorb the heat in the water in the first heat exchanger 2, thereby cooling the water in the first heat exchanger 2, and then the cooled water will be transported to the water-using equipment through the first heat exchanger 2 to realize the cooling function of the air source heat pump 01.

[0073] When the air source heat pump 01 is in the heating state, the compressor 8 will compress the low-temperature refrigerant into a high-temperature and high-pressure refrigerant, and push the high-temperature and high-pressure refrigerant into the first heat exchanger 2 (as a condenser), so that the heat in the refrigerant is dissipated into the water in the first heat exchanger 2, and the heated water is transported to the water-using equipment through the first heat exchanger 2. The refrigerant in the first heat exchanger 2 will continue to flow into the second heat exchanger (as an evaporator), absorb the heat in the air through the second heat exchanger, and then flow into the compressor 8, and be compressed into a high-temperature and high-pressure refrigerant by the compressor 8 again, thereby circulating and heating the water in the first heat exchanger 2, thereby realizing the heating function of the air source heat pump 01.

[0074] In order to facilitate the connection between the water inlet pipe 21 and the water outlet pipe 22 and the housing 1, as shown in FIG. Figure 2 , Figure 5 As shown, the air source heat pump 01 provided in the present application further includes a positioning member 5. The positioning member 5 is disposed in the accommodating cavity 1A and connected to the housing 1. Figure 6 As shown, the positioning member 5 is formed with a first positioning hole 5A and a second positioning hole 5B, the water inlet end of the water inlet pipe 21 extends into the first positioning hole 5A and is connected to the positioning member 5, and the water outlet end of the water outlet pipe 22 extends into the second positioning hole 5B and is connected to the positioning member 5.

[0075] In this way, by connecting the first positioning hole 5A to the water inlet pipe 21 and the second positioning hole 5B to the water outlet pipe 22, the positioning member 5 can position the water inlet pipe 21 and the water outlet pipe 22, so that the metal pipe and the water outlet pipe 22 can be accurately connected to the through hole on the shell 1, so that the shell 1 can be located in the correct connection position, thereby ensuring the overall aesthetics of the air source heat pump 01.

[0076] Exemplarily, the positioning member 5 may be a positioning vertical plate, which is connected to the housing 1 and has a first positioning hole 5A and a second positioning hole 5B formed thereon.

[0077] For example, Figure 5 , Figure 7 As shown, the positioning member 5 includes a baffle 51, and one side of the accommodating cavity 1A formed by the housing 1 has an opening ( Figure 5 Specifically, the opening is located between the base 11 and the top plate 12.

[0078] By setting the opening, the first heat exchanger 2 can be more conveniently fixed on the partition 3, and then the positioning member 5 can be installed on the shell 1, and the water inlet pipe 21 passes through the first positioning hole 5A, and the water outlet pipe 22 passes through the second positioning hole 5B, so that the water inlet pipe 21 and the water outlet pipe 22 can be positioned by the baffle 51 on the positioning member 5.

[0079] Under the above conditions, the air source heat pump 01 further includes a cover plate 6, which is connected to the housing 1 and is located at the opening of the accommodating chamber 1A to block the opening of the accommodating chamber 1A. Figure 7 As shown, a mounting hole 6A is formed on the cover plate 6. A baffle plate 51 is connected to the cover plate 6 and is located at the mounting hole 6A, and a first positioning hole 5A and a second positioning hole 5B are formed on the baffle plate 51. The water inlet end of the water inlet pipe 21 passes through the first positioning hole 5A and extends into the mounting hole 6A, and the water outlet end of the water outlet pipe 22 passes through the second positioning hole 5B and extends into the mounting hole 6A.

[0080] For example, the cover plate 6 and the housing 1 may be connected together by screwing or clamping, or by welding or riveting.

[0081] Through the above-mentioned arrangement, after the water inlet pipe 21 and the water outlet pipe 22 are positioned by the baffle 51, the cover plate 6 can be connected to the shell 1, and the cover plate 6 and the baffle 51 are connected so that the baffle 51 is located at the mounting hole 6A, so that the water inlet pipe 21 and the water outlet pipe 22 extend into the mounting hole 6A.

[0082] Specifically, the air source heat pump 01 further includes a first fastener, and the baffle 51 is connected to the cover plate 6 via the first fastener.

[0083] Exemplarily, the first fastener may be a screw, and the baffle plate 51 and the cover plate 6 are connected together by the screw, thereby facilitating the connection between the baffle plate 51 and the cover plate 6 .

[0084] Alternatively, the first fasteners may also be bolts and nuts, which can also facilitate the connection between the baffle plate 51 and the cover plate 6 .

[0085] In this way, through the positioning effect of the first positioning hole 5A on the baffle plate 51 on the water inlet pipe 21 and the positioning effect of the second positioning hole 5B on the water outlet pipe 22, the water inlet pipe 21 and the water outlet pipe 22 can be accurately extended into the mounting hole 6A. In this way, when connecting the cover plate 6 and the shell 1, it is only necessary to connect the cover plate 6 and the baffle plate 51, so that the cover plate 6 can be accurately installed on the shell 1, which can facilitate the installation of the water inlet pipe 21 and the water outlet pipe 22.

[0086] Furthermore, since the baffle 51 is provided, when the first heat exchanger 2 is installed in the shell 1, it is only necessary to first connect the water inlet pipe 21 and the water outlet pipe 22 to the baffle 51, and then connect the baffle 51 to the cover plate 6. Compared with directly connecting the positioned water inlet pipe 21 and the water outlet pipe 22 to the shell 1, there is a larger operating space around the baffle 51, which can further facilitate the installation of the water inlet pipe 21 and the water outlet pipe 22.

[0087] In addition, through the positioning function of the baffle 51, the cover plate 6 can be more accurately connected to the shell 1. Therefore, after the first heat exchanger 2 is installed, the cover plate 6 and the baffle 51 can more accurately block the opening of the accommodating cavity 1A to improve the overall aesthetics of the air source heat pump 01.

[0088] Specifically, Figure 2 As shown, the housing includes a side plate 13 and a surrounding plate, the side plate 13 is connected between the base 11 and the top plate 12, the side plate 13 and the surrounding plate are respectively connected to both ends of the cover plate 6 in the second direction, the second direction is perpendicular to the arrangement direction of the base 11 and the top plate 12, and perpendicular to the thickness direction of the cover plate 6, and the side plate 13 is connected to the surrounding plate. The side plate 13 and the surrounding plate are connected in sequence to enclose the accommodating cavity 1A together with the base 11 and the top plate 12, and the cover plate 6 blocks the opening of the accommodating cavity 1A.

[0089] In some examples, such as Figure 2 As shown, the enclosure includes an air outlet plate 14, a side wall plate 16, and a rear wall plate 15 connected in sequence, and the air outlet plate 14 is connected to the side plate 13, and the rear wall plate 15 is connected to the cover plate 6. Exemplarily, the plane where the air outlet plate 14 is located is parallel to the plane where the side plate 13 is located, and the air outlet plate 14 is located on the side of the side plate 13 away from the cover plate 6, the second heat exchanger corresponds to the air outlet plate 14, and a fan is provided on the air outlet plate 14 to dissipate heat for the second heat exchanger. The plane where the side wall plate 16 is located is parallel to the plane where the cover plate 6 is located, and is located on the side of the air outlet plate 14 away from the cover plate 6. The rear wall plate 15 is connected to the base 11, the top plate 12, the cover plate 6 and the side wall plate 16, and is spaced from the air outlet plate 14, and the plane where the rear wall plate 15 is located is parallel to the plane where the air outlet plate 14 is located. The base 11, the top plate 12, the side plate 13, the air outlet plate 14, the rear wall plate 15 and the side wall plate 16 are connected to form an accommodating chamber 1A.

[0090] In some examples, fixing plates are provided on the outer peripheral walls of the water inlet pipe 21 and the outer peripheral walls of the water outlet pipe 22, and the baffle 51 is screwed together with the fixing plates on the water inlet pipe 21 and the water outlet pipe 22, so that the water inlet pipe 21 and the water outlet pipe 22 can be more stably connected to the shell 1.

[0091] In some examples, such as Figure 2 , Figure 8 As shown, the air source heat pump 01 further includes a reinforcing plate 7. One end of the reinforcing plate 7 is connected to the partition 3, and the other end of the reinforcing plate 7 is connected to the cover plate 6 and the baffle 51, thereby improving the stability of the cover plate 6 being arranged at the opening and enabling the baffle 51 to be more stably connected to the mounting hole 6A.

[0092] The air source heat pump 01 is usually placed on the roof or on the ground outdoors, and for centralized heating environments or large buildings, multiple air source heat pumps 01 are usually required. Multiple air source heat pumps 01 are arranged at intervals in the horizontal direction, which will result in the air source heat pump 01 occupying a larger horizontal space.

[0093] Based on this, in order to reasonably utilize the space in the accommodating cavity 1A, as Figure 8 As shown, the first heat exchanger 2 is arranged above the compressor 8.

[0094] Through the above-mentioned arrangement, the first heat exchanger 2 and the compressor 8 are arranged at intervals in the vertical direction. Compared with the first heat exchanger 2 and the compressor 8 being arranged at intervals in the horizontal direction, the space of the air source heat pump 01 in the vertical direction can be reasonably utilized to reduce the space occupied by the first heat exchanger 2 and the compressor 8 in the horizontal direction. In this way, the space occupied by the air source heat pump 01 in the horizontal direction can be reduced, so that more air source heat pumps 01 can be arranged in a certain space, thereby improving the utilization rate of the space for placing the air source heat pump 01.

[0095] In order to facilitate the baffle 51 to position the water inlet pipe 21 and the water outlet pipe 22, in some embodiments, such as Fig. 9 , Fig.10 As shown, the positioning member 5 also includes a bracket 52, and the bracket 52 is connected to the housing 1. Fig.10 , Fig.11 As shown, a third positioning hole 52A is formed on the bracket 52, and a positioning folded edge 511 is formed on the baffle 51, and the positioning folded edge 511 extends into the third positioning hole 52A.

[0096] Through the above arrangement, after the first heat exchanger 2 is connected to the shell 1, the bracket 52 can be connected to the shell 1 first, and then the positioning fold 511 on the baffle 51 is extended into the third positioning hole 52A on the bracket 52, and the baffle 51 and the bracket 52 are abutted, and the baffle 51 is positioned through the third positioning hole 52A, and then the water inlet pipe 21 and the water outlet pipe 22 of the first heat exchanger 2 are positioned through the baffle 51.

[0097] Exemplarily, the positioning fold 511 may be formed by bending one end of the baffle 51 , or may be formed by connecting the end of the baffle 51 to a plate body.

[0098] In this way, when positioning the water inlet pipe 21 and the water outlet pipe 22 of the first heat exchanger 2, it is only necessary to accurately connect the bracket 52 to the required position on the shell 1, and the water inlet pipe 21 and the water outlet pipe 22 can be positioned through the baffle 51. This can facilitate the setting of the baffle 51 and facilitate the positioning of the water inlet pipe 21 and the water outlet pipe 22.

[0099] Specifically, the air source heat pump 01 further includes a second fastener, and the baffle 51 is connected to the bracket 52 via the second fastener.

[0100] Exemplarily, the second fastener may be a screw, and the baffle 51 and the bracket 52 are connected together by the screw, thereby facilitating the connection between the baffle 51 and the bracket 52 .

[0101] Alternatively, the second fasteners may also be bolts and nuts, which can also facilitate the connection between the baffle 51 and the bracket 52 .

[0102] For example, the bracket 52 and the housing 1 may be connected together by screwing or clamping, or by welding or riveting.

[0103] Exemplarily, the bracket 52 may be connected to the housing or to the base 11 .

[0104] Specifically, Fig.12 As shown, the bracket 52 also includes a screw plate 523, a fourth positioning hole 52B is formed on the screw plate 523, and the screw plate 523 is connected to one end of the connection portion 521 close to the bottom wall N of the accommodating chamber 1A, the plane where the screw plate 523 is located is parallel to the plane where the bottom wall N of the accommodating chamber 1A is located, and the connecting plate 4 is in contact with the bottom wall N of the accommodating chamber 1A. A screw hole is formed on the bottom wall N of the accommodating chamber 1A, and the air source heat pump 01 also includes a third fastener, which passes through the fourth positioning hole 52B and is connected to the corresponding screw hole.

[0105] Exemplarily, the third fastener may be a screw that passes through the fourth positioning hole 52B and is threadedly connected to the corresponding screw hole, or may be a bolt and a nut that cooperate to connect the bracket 52 to the bottom wall N.

[0106] Through the above arrangement, the third fastener passes through the fourth positioning hole 52B and is connected with the corresponding screw hole, so that the bracket 52 can be positioned, so that the bracket 52 can be accurately connected to the required position on the bottom wall N of the accommodating chamber 1A, thereby facilitating the bracket 52 to position the baffle 51, and then facilitating the first positioning hole 5A and the second positioning hole 5B on the baffle 51 to position the water inlet pipe 21 and the water outlet pipe 22. In addition, since the screw plate 523 is in contact with the bottom wall N of the accommodating chamber 1A, the screw plate 523 can also support the connecting portion 521, so that the connecting portion 521 can be more stably connected to the bottom wall N of the accommodating chamber 1A.

[0107] The baffle 51 and the cover plate 6 are connected together by a first fastener, wherein the first fastener can be a screw; the baffle 51 and the bracket 52 are connected together by a second fastener, wherein the second fastener can also be a screw. In this way, since the baffle 51 is connected to the cover plate 6 by the first fastener, and the baffle 51 is connected to the bracket 52 by the second fastener, the baffle 51, the bracket 52 and the cover plate 6 can be connected to each other, so that the structural stability between the bracket 52, the baffle 51 and the cover plate 6 can be improved, thereby ensuring the positioning effect of the baffle 51 on the water inlet pipe 21 and the water outlet pipe 22.

[0108] In addition, since a bracket 52 is provided, the bracket 52 is connected to the bottom wall N, and since the water inlet pipe 21 and the water outlet pipe 22 are connected to the baffle 51, and the baffle 51 is connected to the bracket 52, the bottom wall N can support the bracket 52, and then the bracket 52 supports the baffle 51, so that the baffle 51 supports the water inlet pipe 21 and the water outlet pipe 22. In this way, the bracket 52 and the connecting plate 4 can jointly support the first heat exchanger 2, so that the first heat exchanger 2 can be more stably connected to the shell 1, and then more stably arranged in the accommodating cavity 1A.

[0109] In order to enable the bracket 52 to support the baffle 51 more stably, so as to position the water inlet pipe 21 and the water outlet pipe 22 through the baffle 51, in some embodiments, as Fig. 9 , Fig.13 As shown, the accommodating chamber 1A has a bottom wall N, and specifically, the bottom wall N can be a base 11. The wall surface of the bottom wall N is perpendicular to the plane where the opening of the accommodating chamber 1A is located. The bracket 52 includes a connecting portion 521 and a supporting portion 522, and the connecting portion 521 is connected to the bottom wall N. The third positioning hole 52A is opened in the connecting portion 521. The supporting portion 522 is connected to the connecting portion 521, as shown in FIG. Fig.13 , Fig.14 As shown, the baffle 51 is disposed on a side of the support portion 522 away from the bottom wall N, and is in contact with the support portion 522 .

[0110] Exemplarily, the connecting portion 521 and the supporting portion 522 may be plate-shaped or column-shaped.

[0111] Exemplarily, the support portion 522 and the connection portion 521 may be an integrally formed structure, which can increase the overall structural strength of the two and avoid secondary processing.

[0112] Alternatively, the support portion 522 and the connection portion 521 may also be separate structures, and the support portion 522 and the connection portion 521 may be processed separately, and then connected together by any suitable means such as welding or screwing.

[0113] In this way, after the positioning folded edge 511 on the baffle 51 is extended into the third mounting hole 6A on the connecting portion 521, and the baffle 51 and the connecting portion 521 are abutted, the supporting portion 522 can contact the side of the baffle 51 close to the bottom wall N of the accommodating chamber 1A, thereby providing support for the baffle 51, so that the baffle 51 can be more stably connected to the bracket 52, thereby ensuring the first positioning hole 5A on the baffle 51 has a positioning effect on the water inlet pipe 21 and the second positioning hole 5B has a positioning effect on the water outlet pipe 22.

[0114] On the basis of the above, in order to facilitate the connection of the bracket 52 to the required position on the bottom wall N of the accommodating chamber 1A, in some embodiments, such as Fig.12 , Fig.15 As shown, the housing 1 further includes a positioning plate 9 , which is disposed on the bottom wall N. The bracket 52 further includes a positioning portion 524 , which is connected to the connecting portion 521 and contacts the positioning plate 9 .

[0115] Exemplarily, the thickness direction of the positioning plate 9 may be perpendicular to the arrangement direction of the top plate 12 and the base 11 , or may intersect with the arrangement direction of the top plate 12 and the base 11 .

[0116] Exemplarily, the positioning portion 524 can be an abutment plate, wherein the abutment plate can directly abut against the positioning plate 9, or one end of the abutment plate close to the positioning plate 9 can be bent along the direction of the top plate 12 away from the base 11 to form an abutment folded edge, and the plane where the abutment folded edge is located is parallel to the plane where the positioning plate 9 is located, and abuts against the positioning plate 9.

[0117] Alternatively, the positioning portion 524 may also be a positioning block, and a surface of the positioning block close to the positioning plate 9 abuts against the positioning plate 9 .

[0118] In this way, when connecting the bracket 52 to the bottom wall N of the accommodating chamber 1A, the positioning portion 524 can be abutted against the positioning plate 9 on the bottom wall N so that the positioning plate 9 limits the positioning portion 524, and then the bracket 52 is moved along the positioning plate 9 and moved to the required position on the bottom wall N, and then the bracket 52 is connected to the bottom wall N of the accommodating chamber 1A, so that the bracket 52 is accurately connected to the bottom wall N of the accommodating chamber 1A. In this way, the bracket 52 can be quickly moved to the required position on the bottom wall N of the accommodating chamber 1A to facilitate the connection between the bracket 52 and the bottom wall N of the accommodating chamber 1A.

[0119] Since components such as the compressor 8 and the first heat exchanger 2 are arranged between the partition 3 and the cover plate 6, and since the side plate 13 is connected between the base 11 and the top plate 12, rainwater and the like may drip onto the components between the partition 3 and the cover plate 6 through the gap between the side plate 13 and the top plate 12, thereby affecting the normal functions of the components.

[0120] In order to avoid the above problems, in some embodiments, Fig.16 As shown, the air source heat pump 01 further includes a seal 10 , which is sealedly connected to both the top plate 12 and the side plate 13 .

[0121] In this way, when rainwater flows to the gap between the top plate 12 and the side plate 13, since the seal 10 is sealed and connected to both the top plate 12 and the side plate 13, the seal 10 can prevent rainwater from entering between the partition plate 3 and the cover plate 6 from the gap between the top plate 12 and the side plate 13, thereby preventing the components between the cover plate 6 and the partition plate 3 from being affected by rainwater, thereby ensuring the normal function of the components between the cover plate 6 and the partition plate 3 and ensuring the normal use of the air source heat pump 01.

[0122] Exemplarily, the sealing member 10 may be a sealing strip, which is bonded between the top plate 12 and the side plate 13 .

[0123] For example, Fig.17 , Fig.18 As shown, the sealing member 10 includes a fixing member 101, a first sealing gasket 102 and a second sealing gasket 103. The fixing member 101 is arranged on one side of the side plate 13. The first sealing gasket 102 is connected to the upper side of the fixing member 101. The second sealing gasket 103 is connected to the upper side of the fixing member 101 and is located on the side of the first sealing gasket 102 away from the side plate 13. A portion of the top plate 12 is located on the upper side of the first sealing gasket 102 and abuts against the first sealing gasket 102. A bending portion is formed at one end of the side plate 13 away from the base 11. The bending portion is bent along the direction of the side plate 13 pointing to the fixing member 101. The bending portion is located above the second sealing gasket 103 and abuts against the second sealing gasket 103.

[0124] Through the above-mentioned arrangement, the fixing member 101 can provide support for the first sealing gasket 102 and the second sealing gasket 103, so that the first sealing gasket 102 can seal the fixing member 101 and the top plate 12, thereby preventing rainwater and the like from flowing into the accommodating cavity 1A from between the fixing member 101 and the top plate 12, and the second sealing gasket 103 can seal the fixing member 101 and the side plate 13, thereby preventing rainwater and the like from flowing into the accommodating cavity 1A from between the fixing member 101 and the side plate 13.

[0125] In this way, the fixing member 101, the first sealing gasket 102 and the second sealing gasket 103 can seal the gap between the side plate 13 and the top plate 12, thereby preventing the components between the cover plate 6 and the partition plate 3 from being affected by rainwater, thereby ensuring the normal use of the air source heat pump 01.

[0126] In some examples, the fixing member 101 is screwed together with the side plate 13 and the top plate 12 so that the fixing member 101 can provide stable support for the first sealing gasket 102 and the second sealing gasket 103, so that the first sealing gasket 102 seals the top plate 12 and the fixing member 101, and the second sealing gasket 103 seals the side plate 13 and the fixing member 101.

[0127] Exemplarily, a side of the first sealing gasket 102 close to the second sealing gasket 103 abuts against a side of the second sealing gasket 103 close to the first sealing gasket 102 .

[0128] For example, Fig.19 , Fig. 20 As shown, the first sealing gasket 102 and the second sealing gasket 103 are arranged at intervals, a plurality of vertical plates 104 are arranged on the fixing member 101, the planes where the plurality of vertical plates 104 are located are all perpendicular to the second direction, and the plurality of vertical plates 104 are arranged at intervals along the first direction.

[0129] A groove is formed between two adjacent vertical plates 104, so that a plurality of grooves are formed between the plurality of vertical plates 104 at intervals along the first direction. The first sealing gasket 102 is disposed in one groove and abuts against the inner wall of the groove. The second sealing gasket 103 is disposed in another groove and abuts against the inner wall of the groove. At least one groove is disposed between the groove where the first sealing gasket 102 is located and the groove where the second sealing gasket 103 is located, and at least one groove between the groove where the first sealing gasket 102 is located and the groove where the second sealing gasket 103 is located forms a water guide groove 105.

[0130] Through the above arrangement, the plurality of vertical plates 104 can fix a sealing gasket and a second sealing gasket 103, so that the first sealing gasket 102 and the second sealing gasket 103 can be arranged at intervals on the fixing member 101, so that when rainwater flows onto the sealing member 10, it will flow from the first sealing gasket 102 and the second sealing gasket 103 into the water guide groove 105, and finally flow out from the water guide groove 105. In this way, the water guide groove 105 can remove rainwater from the air source heat pump 01, and prevent rainwater from accumulating above the air source heat pump 01, so as to further reduce the probability of rainwater flowing from the gap between the side plate 13 and the top plate 12 into the gap between the cover plate 6 and the partition plate 3, and ensure the normal use of the air source heat pump 01.
