[0020] In an optional embodiment, the water module assembly further includes a plate heat exchanger, and the plate heat exchanger is disposed close to the right side of the sound insulation cover.

[0021] The plate heat exchanger is arranged close to the right side of the sound insulation cover to form an intermediate space and improve the compactness of the structure.

[0022] In an optional embodiment, the integrated heat pump further comprises a bracket, wherein the bracket is erected on the front side of the second chamber, the electric heater is disposed on the bracket, and the plate heat exchanger is located below the electric heater.

DETAILED DESCRIPTION

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 FIG. 1 is a schematic diagram of the structure of the integrated heat pump 100 provided in this embodiment. Figure 2 Shown Figure 1A schematic diagram of the structure of some structures in the first perspective. Figure 3 Shown Figure 1 Schematic diagram of the structure of part of the structure under the second perspective.

[0045] The integrated heat pump 100 provided in this embodiment includes a box body 110, a fan 120, a compressor (not shown in the figure), a refrigerant side electrical control box 130, a water module pipeline 140 and a water module assembly. The water module assembly includes a water module electrical control box 151, an expansion tank 152, an electric heater 153, a water pump 154 ​​and a plate heat exchanger 155. The expansion tank 152, the electric heater 153, the water pump 154 ​​and the plate heat exchanger 155 are all arranged on the water module pipeline 140.

[0046] The integrated heat pump 100 also includes a wind-blocking plate 160 erected in the box body 110, which divides the internal space of the box body 110 into a first chamber 111 and a second chamber 112 spaced apart from left to right. The fan 120 is arranged in the first chamber 111, the compressor, the water module pipeline 140 and the water module assembly are arranged in the second chamber 112, and the refrigerant side electrical control box 130 is arranged on the top of the wind-blocking plate 160.

[0047] The box body 110 includes a bottom plate 113, a front panel, a rear side plate 114, a right side plate 115, an evaporator 116 and a top cover (not shown in the figure). The front panel, the rear side plate 114, the right side plate 115, the evaporator 116 and the wind-blocking vertical plate 160 are all arranged between the bottom plate 113 and the top cover. The front panel and the rear side plate 114 are arranged opposite to each other in the front-to-back direction, and the wind-blocking vertical plate 160 and the right side plate 115 are arranged opposite to each other in the left-right direction.

[0048] The left side of the wind-blocking plate 160, the front panel, and the evaporator 116 together form a first chamber 111, and the right side of the wind-blocking plate 160, the front panel, the rear side panel 114, and the right side panel 115 together form a second chamber 112. In this embodiment, the front panel includes a fan 120 grille that participates in the formation of the first chamber 111, and a small panel 117 that participates in the formation of the second chamber 112.

[0049] In this embodiment, the water module electrical control box 151 is arranged on the right side of the second chamber 112, the expansion tank 152 is arranged on the rear side of the second chamber 112, the compressor is arranged on the left side of the second chamber 112, the electric heater 153 is arranged on the front side of the second chamber 112, and the water module pipeline 140 is arranged in the space surrounded by the water module electrical control box 151, the expansion tank 152, the compressor and the electric heater 153.

[0050] It can be seen that the water module electric control, expansion tank 152, compressor and electric heater 153 are arranged in the second chamber 112, so as to make full use of the internal space of the second chamber 112, and form an intermediate cavity for accommodating the water module pipeline 140. The water module pipeline 140 is accommodated in the intermediate cavity, which can minimize the length of the pipeline and further improve the compactness of the structure. In other words, the integrated heat pump 100 provided in this embodiment has the characteristics of more compact structure and smaller installation space.

[0051] Specifically, the water module electric control box 151 is disposed on the upper right side of the second chamber 112, and the water pump 154 ​​is disposed on the lower right side of the second chamber 112. By arranging the water module electric control box 151 and the water pump 154 ​​in the vertical direction, the utilization rate of the internal space of the second chamber 112 is further improved. In addition, the length of the connection cable between the water pump 154 ​​and the water module electric control box 151 can be greatly reduced, further improving the compactness of the structure.

[0052] And, the water pump 154 ​​is located below the expansion tank 152. It is understandable that the water pump 154 ​​is actually located at the bottom of the right rear of the second chamber 112, and the water pump 154 ​​is actually installed on the rear side plate 114, so as to fully utilize the angle space of the right rear of the second chamber 112.

[0053] The integrated heat pump 100 further includes a soundproof cover 170, which is disposed on the left side of the second chamber 112, and the compressor is disposed inside the soundproof cover 170. The soundproof cover 170 is actually a sandwich structure, and sound insulation material is disposed in the sandwich.

[0054] In actual applications, the compressor will generate relatively large noise when in operation. In this embodiment, an additional soundproof cover 170 is configured to house the compressor, thereby effectively shielding the compressor noise, thereby significantly improving the user experience.

[0055] In this embodiment, the plate heat exchanger 155 is disposed close to the right side of the soundproof cover 170. In other words, the plate heat exchanger 155 and the other water module components actually enclose an intermediate space for accommodating the water module pipeline 140.

[0056] The integrated heat pump 100 further includes a bracket 180 , which is vertically disposed at the front side of the second chamber 112 . The electric heater 153 is disposed on the bracket 180 , and the plate heat exchanger 155 is located below the electric heater 153 .

[0057] In fact, the bracket 180 is erected on the bottom plate 113, and the inner surface of the small panel 117 is connected to the bracket 180. The bracket 180 plays the role of installing the electric heater 153 on the one hand, and plays the role of supporting and strengthening the structure of the small panel 117 on the other hand. In this embodiment, a mounting member 1151 structure is also provided on the bracket 180 below the electric heater 153 and near the soundproof cover 170, and the electric heater is installed at the mounting structure.

[0058] It can be understood that the installation of the plate heat exchanger 155 fully utilizes the angle space formed by the bracket 180 and the sound insulation cover 170, and the plate heat exchanger 155 is located below the electric heater 153, which realizes the rational utilization of the front lower space of the second chamber 112, further improves the space utilization rate of the second chamber 112, and makes the overall structure more compact.

[0059] Please refer to Figure 4 , Figure 4 Shown is a schematic structural diagram of the wind-blocking vertical plate 160 .

[0060] Regarding the installation of the refrigerant side electrical control box 130 on the wind shielding plate 160, in the present embodiment, a mounting notch 161 is provided at the top of the wind shielding plate 160, and the refrigerant side electrical control box 130 is embedded in the mounting notch 161. A support plate 162 which forms an angle with the vertical direction is provided at the bottom of the mounting notch 161, and the support plate 162 supports the refrigerant side electrical control box 130.

[0061] It is understandable that, since the refrigerant side electric control box 130 is embedded in the installation notch 161 opened at the top of the windproof vertical plate 160, the refrigerant side electric control box 130 does not occupy too much vertical space, further improving the compactness of the structure. In addition, the support plate 162 provided at the bottom of the installation notch 161 is actually parallel to the horizontal plane, which can provide reliable support for the refrigerant side electric control box 130, thereby ensuring that the refrigerant side electric control box 130 is stably installed on the windproof vertical plate 160.

[0062] The water module electric control box 151 is located on the inner side of the right side plate 115. In this embodiment, the water module electric control box 151 is arranged between the bracket 180 and the rear side plate 114 in the front-to-back direction. Specifically, one side of the water module electric control box 151 cooperates with the bracket 180, and one side of the water module electric control box 151 away from the bracket 180 is rotatably connected to the box body 110, and the rotation centerline extends in the vertical direction.

[0063] In fact, the cooperation between the water module electric control box 151 and the bracket 180 realizes the positioning of the water module electric control box 151, so as to establish a connection between the water module electric control box 151 and the rear side plate 114, thereby completing the installation of the water module electric control box 151. After the water module electric control box 151 is installed on the rear side plate 114, the water module electric control box 151 can be rotated relative to the rear side plate 114 to a state of cooperation with the bracket 180 and a state of discoupling.

[0064] Please refer to Figure 5 and Figure 6 , Figure 5 It is a schematic diagram of the matching structure of the bracket 180 and the water module electric control box 151. Figure 6 Shown Figure 5 A magnified schematic diagram of area A in the middle.

[0065] A positioning portion 181 is provided on the bracket 180 , and a matching portion 156 is provided on a side of the water module electric control box 151 away from the rear side plate 114 , and the matching portion 156 matches with the positioning portion 181 .

[0066] Specifically, the positioning portion 181 is provided with a connector 1811 extending in the left-right direction, and the matching portion 156 is provided with a slot 1561 . The slot 1561 penetrates the matching portion 156 in the front-back direction, and the connector 1811 is plugged into the slot 1561 .

[0067] It is understandable that before installing the water module electric control box 151, the bracket 180 and the rear side plate 114 have been erected on the bottom plate 113 in advance and have established a connection with the bottom plate 113. When installing the water module electric control box 151, first plug the slot 1561 provided on the matching portion 156 on the water module electric control box 151 into the plug-in connector 1811 provided on the positioning portion 181 of the bracket 180. After the plug-in is completed, the plug-in connector 1811 plays a role in supporting and positioning the water module electric control box 151. At this time, the side of the water module electric control box 151 away from the matching portion 156 is connected to the rear side plate 114 to ensure the accuracy of the connection position.

[0068] In order to ensure that the connector 1811 firmly supports the water module electrical control box 151 and accurately positions it, in this embodiment, there are multiple connectors 1811, and the multiple connectors 1811 are arranged in sequence in the vertical direction; there are multiple slots 1561, and the multiple slots 1561 are arranged in sequence in the vertical direction, and the multiple connectors 1811 are connected to the multiple slots 1561 in a one-to-one correspondence.

[0069] In order to further enhance the positioning effect of the bracket 180 on the water module electrical control box 151, in this embodiment, the positioning portion 181 has a positioning wall 1812, and the connector 1811 is protruded on the positioning wall 1812; the mating portion 156 has a mating wall 1562, and the slot 1561 is penetrated and arranged on the mating wall 1562, and the positioning wall 1812 and the mating wall 1562 are arranged opposite to each other.

[0070] It can be understood that when the multiple connectors 1811 protruding from the positioning wall 1812 are plugged into the multiple slots 1561 penetrating through the matching wall 1562 in a one-to-one correspondence, the positioning wall 1812 corresponds to the matching wall 1562, that is, the two are almost in contact.

[0071] In this state, on the one hand, the connection between the connector 1811 and the slot 1561 supports the water module electrical control box 151, and on the other hand, the positioning wall 1812 also limits the matching wall 1562 to a certain extent, preventing the matching wall 1562 from deflecting on the surface of the positioning wall 1812, thereby improving the positioning accuracy of the water module electrical control box 151 and obtaining a better positioning effect.

[0072] In addition, in this embodiment, the matching portion 156 further has a connecting wall 1563 , and the matching wall 1562 is connected to the water module electric control box 151 via the connecting wall 1563 , and the matching wall 1562 and the connecting wall 1563 form an angle.

[0073] The mating wall 1562 and the connecting wall 1563 are both sheet metal. The mating wall 1562 is connected to the water module electrical control box 151 via the connecting wall 1563. The state of the mating wall 1562 can be adjusted by adjusting the angle between the connecting wall 1563 and the water module electrical control box 151, and between the mating wall 1562 and the connecting wall 1563, including the distance between the mating wall 1562 and the water module electrical control box 151, the angle between the mating wall 1562 and the water module electrical control box 151, etc., to adapt to different assembly conditions.

[0074] In this embodiment, the connector 1811 is in a sheet shape, the plane where the connector 1811 is located is parallel to the vertical direction, and the slot 1561 is a strip-shaped slot whose length direction is parallel to the vertical direction.

[0075] Since the slot 1561 is a strip groove parallel to the length direction and the vertical direction, when the connector 1811 is plugged into the slot 1561, the connector 1811 can not only support the water module electrical control box 151, but also prevent the water module electrical control box 151 from deflecting in the vertical plane, thereby ensuring positioning accuracy.

[0076] It can be seen that the integrated heat pump 100 provided in this embodiment has the characteristics of convenient installation and high installation precision of the water module electric control box 151.

[0077] Please refer to Figure 7 and Figure 8 , Figure 7 Shown Figure 1 A schematic diagram of the structure of some structures in the third perspective. Figure 8 Shown Figure 7 A magnified schematic diagram of area B.

[0078] Considering that in actual applications, there is a situation where the amount of water in the water module pipeline 140 is too large and some of the water needs to be discharged. When draining water, the products currently on the market need to extend the external pipe into the interior of the box 110 because the drain valve 141 is set inside the box 110, so as to connect with the joint reserved in the water module pipeline 140 inside the box 110, so as to discharge some of the water in the water module pipeline 140 into the external pipe.

[0079] When such products are draining water, the space for pipe connection operation is extremely limited due to the arrangement of internal components of the housing 110, which makes pipe connection extremely difficult and the drainage operation is time-consuming and laborious. In order to solve this problem, the integrated heat pump 100 provided in this embodiment further includes a drain pipe 190, a drain valve 141 is provided on the water module pipe 140, and a drain nozzle 118 is provided on the housing 110. One end of the drain pipe 190 is connected to the drain valve 141, and the other end is connected to the drain nozzle 118.

[0080] In actual application, when the water module pipeline 140 needs to be drained, it is only necessary to open the drain valve 141. After the drain valve 141 is opened, the water in the water module pipeline 140 flows into the drain pipeline 190 through the drain valve 141, and flows out to the outside through the drain pipeline 190 and the drain nozzle 118. If it is necessary to collect the discharged water through an external pipe, it is only necessary to connect the external pipe to the drain nozzle 118 provided on the box body 110. Since the drain nozzle 118 is provided on the box body 110, the pipe operation is not blocked by internal components, which is convenient and quick.

[0081] In this embodiment, one end of the drain pipe 190 away from the drain valve 141 is plugged into one end of the drain nozzle 118, and the other end of the drain nozzle 118 extends to the outside of the box 110. In other embodiments, in order to ensure the reliability and sealing of the connection between the drain pipe 190 and the drain nozzle 118, a variety of connection methods including threaded fitting, welding, etc. can be used between the two.

[0082] Please refer to Fig. 9 , Fig. 9 Shown is a schematic structural diagram of the drain pipe 190.

[0083] In this embodiment, a connecting piece 191 is provided at one end of the drain pipe 190 away from the drain valve 141 , and the connecting piece 191 is connected to the box body 110 .

[0084] In fact, one end of the drain pipe 190 plugged with the drain nozzle 118 passes through the connecting piece 191, and the connecting piece 191 is penetrated with a plurality of through holes distributed around the drain pipe 190. The box body 110 is correspondingly provided with a plurality of threaded holes distributed around the drain nozzle 118.

[0085] When connecting the drain pipe 190 to the drain nozzle 118, it is only necessary to insert the end of the drain pipe 190 away from the drain valve 141 into the drain nozzle 118 until the connecting piece 191 contacts the box body 110. At this time, the position of the drain pipe 190 is adjusted so that the multiple through holes on the connecting piece 191 correspond to the multiple threaded holes on the box body 110. Finally, the connection and fixation of the connecting piece 191 to the box body 110 are achieved by passing the multiple through holes through the multiple threaded connectors and screwing them into the multiple threaded holes, thereby completing the locking of the drain pipe 190 and the drain nozzle 118.

[0086] In this embodiment, the box body 110 also includes an expansion tank mounting plate 119, please refer to Fig.10 , Fig.10 It is a schematic structural diagram of the expansion tank mounting plate 119.

[0087] The expansion tank mounting plate 119 is arranged on the inner surface of the rear side plate 114 , and the expansion tank 152 is mounted on the expansion tank mounting plate 119 . A through hole 1141 is penetrated through the rear side plate 114 , and the drain nozzle 118 passes through the through hole 1141 , that is, extends to the outside of the box body 110 .

[0088] It can be understood that, through the plug-in cooperation between the drain nozzle 118 and the through hole 1141, the expansion tank mounting plate 119 is positioned on the rear side plate 114, ensuring that the expansion tube mounting plate can be quickly installed on the rear side plate 114, reducing the difficulty of assembly.

[0089] In other embodiments, the drain nozzle 118 may be disposed at other locations of the box body 110 according to actual application conditions.

[0090] In fact, in this embodiment, the drain valve 141 is disposed on the pipe section between the water pump 154 ​​and the electric heater 153 on the water module pipeline 140. In the left-right direction, the water module electric control box 151 corresponds to the drain valve 141, and the water module electric control box 151 can be rotated relative to the rear side plate 114 to open the second chamber 112 to expose the drain valve 141.

[0091] It is understandable that in actual application, it is only necessary to open the right side panel 115 of the box body 110 and rotate the water module electrical control box 151 to open the second chamber 112. The user can then put his hand into the second chamber 112 and directly reach the drain valve 141 without being blocked by other components in the middle, making the operation convenient and quick.

[0092] In this embodiment, the water inlet and outlet of the water module pipeline 140 are arranged on the side of the box body 110 where the drain nozzle 118 is located, and in the vertical direction, the drain nozzle 118 is located above the water inlet and outlet. In other words, the water inlet and outlet of the water module pipeline 140 are arranged on the rear side plate 114 of the box body 110 at a position below the drain nozzle 118.

[0093] In order to facilitate the connection between the drain nozzle 118 and the external connecting pipe, in this embodiment, a connecting pipe structure 1181 is provided on the outer surface of the drain nozzle 118, and the connecting pipe structure 1181 is used to cooperate with the external connecting pipe to connect the drain nozzle 118 with the external connecting pipe.

[0094] Preferably, the connecting pipe structure 1181 is an external thread. In other embodiments, the connecting pipe structure 1181 can be adjusted according to actual application conditions. For example, it can be adjusted to a concave-convex structure that is convenient for plugging with an external connecting pipe.

[0095] It can be seen that the integrated heat pump 100 provided in this embodiment has the characteristic of convenient water discharge from the water module pipeline 140, and the water discharge operation saves time and effort.

[0096] Please refer to Fig.11 and Fig.12 , Fig.11 is a schematic diagram of the connection structure between the small panel 117 and the bracket 180, Fig.12 for Fig.11 Enlarged schematic diagram of area C in the middle.

[0097] In this embodiment, in order to facilitate the connection between the right side plate 115 and the small panel 117 and ensure that the connection between the two is stable and reliable, the bracket 180 is used as the supporting structure of the small panel 117 in advance to ensure that the small panel 117 is erected on the bottom plate 113 in a stable state.

[0098] Specifically, a mounting fold 1171 is provided on the right edge of the small panel 117 , and the mounting fold 1171 is used to establish a connection with the right side panel 115 . A positioning wall 1812 provided on the right edge of the bracket 180 is attached to and connected with the mounting fold 1171 .

[0099] It is understandable that since the small panel 117 is a plate-like structure with a certain height in the vertical direction, even if the bottom of the small panel 117 is connected to the bottom plate 113, it may still shake left and right when connected to the right side plate 115, resulting in increased difficulty in installing the right side plate 115 and unreliable fixation of the right side plate 115 after completion.

[0100] In the present embodiment, the bracket 180 is erected on the base plate 113, and the positioning wall 1812 arranged on the right edge of the bracket 180 is affixed and connected to the mounting fold 1171 of the small panel 117, which is equivalent to the bracket 180 playing a role of structural reinforcement and support for the mounting fold 1171 of the small panel 117, ensuring that the small panel 117 remains stable during the process of assembling the right side plate 115 to the small panel 117.

[0101] In this embodiment, the installation flange 1171 is connected to the positioning wall 1812 by screws. In other embodiments, according to actual application conditions, the installation flange 1171 and the positioning wall 1812 can also be connected by other connection methods including welding and bonding.

[0102] Please refer to Fig.13 , Fig.14 and Fig.15 , Fig.13 It is a schematic diagram of the connection structure of the small panel 117, the bracket 180 and the right side panel 115. Fig.14 Shown Fig.13 The enlarged schematic diagram of the D area in the middle. Fig.15 for Fig.13 A magnified schematic diagram of area E in the middle.

[0103] In this embodiment, a mounting groove 1172 is provided through the mounting fold 1171, and a mounting member 1151 is provided on the front edge of the right side plate 115, and the mounting member 1151 is plugged into the mounting groove 1172. It can be understood that before the right side plate 115 is assembled, the bracket 180 has been erected on the bottom plate 113, and the small panel 117 has been connected to the bracket 180, that is, the small panel 117 is already in a state of being supported by the bracket 180.

[0104] Therefore, when transferring the right side panel 115 to the small panel 117, it is only necessary to align and plug the mounting piece 1151 set on the front edge of the right side panel 115 with the mounting groove 1172 set on the mounting fold 1171 of the small panel 117. During this process, the small panel 117 and the mounting fold 1171 are in a stable state, the plug-in operation can be easily completed, and the plug-in structure is stable and reliable.

[0105] In order to improve the reliability of the connection structure between the small panel 117 and the right side panel 115, in this embodiment, there are multiple mounting grooves 1172, and the multiple mounting grooves 1172 are arranged in sequence in the vertical direction. There are multiple mounting members 1151, and the multiple mounting members 1151 are arranged in sequence in the vertical direction, and the multiple mounting members 1151 are plugged into the multiple mounting grooves 1172 in a one-to-one correspondence.

[0106] It is understandable that, in addition to the small panel 117, the right side panel 115 also needs to be connected to the rear side panel 114 to complete the right side cover of the second chamber 112. In this embodiment, the rear edge of the right side panel 115 is also provided with a mounting member 1151, and the mounting member 1151 disposed on the rear edge of the right side panel 115 is plugged into the rear side panel 114.

[0107] In fact, a folded edge is also provided on the right edge of the rear side panel 114, and a plurality of mounting grooves 1172 are also penetrated through the folded edge. The plurality of mounting parts 1151 provided on the rear edge of the right side panel 115 are also plugged into the plurality of mounting grooves 1172 on the folded edge of the rear side panel 114 one by one.

[0108] In this embodiment, the mounting groove 1172 is a strip-shaped groove whose length direction is parallel to the vertical direction, the mounting member 1151 is in a sheet shape, and the plane where the mounting member 1151 is located is parallel to the vertical direction.

[0109] It can be understood that since the installation groove 1172 is a strip groove whose length direction is parallel to the vertical direction, when the sheet-like installation member 1151 is plugged into the installation groove 1172, the installation member 1151 is limited by the groove wall of the installation groove 1172, which can prevent the right side plate 115 from rotating relative to the small panel 117.

[0110] In addition, a retaining notch 1152 is provided on the upper edge of the mounting member 1151 , and the upper groove edge of the mounting groove 1172 is embedded in the retaining notch 1152 .

[0111] In fact, when the mounting member 1151 is inserted into the mounting groove 1172, the top of the mounting member 1151 is actually below the upper groove edge of the mounting groove 1172, that is, the mounting member 1151 is completely within the range surrounded by the mounting groove 1172 to ensure that the mounting member 1151 can be smoothly inserted. After the mounting member 1151 passes through the mounting groove 1172, the right side plate 115 is lifted up, and the mounting member 1151 moves upward in the mounting groove 1172 until its clamping notch 1152 clamps the upper groove edge of the mounting groove 1172. In this state, the state of the right side plate 115 is fixed by configuring other connecting structures, and the installation of the right side plate 115 can be completed, and the water module electric control box 151 is blocked inside it.

[0112] Since the retaining notch 1152 and the upper groove edge of the installation groove 1172 remain in a retaining state, the mounting member 1151 cannot horizontally exit the installation groove 1172 to the right, that is, there is an additional locking structure between the right side plate 115 and the small panel 117, which can further enhance the stability of the connection structure between the right side plate 115 and the small panel 117.

[0113] In order to further ensure the reliability of the plug-in structure between the mounting member 1151 and the mounting groove 1172 , in this embodiment, reinforcing ribs are provided on the mounting member 1151 to ensure the strength of the mounting member 1151 .

[0114] It is understandable that, since a plurality of mounting grooves 1172 are arranged on the mounting fold 1171 in the vertical direction, and the positioning wall 1812 of the bracket 180 is in contact with the inner side of the mounting fold 1171, it is inevitable that the positioning wall 1812 will cover part of the mounting grooves 1172, thereby blocking the corresponding mounting member 1151 from being plugged in. To solve this problem, in this embodiment, an avoidance groove 1814 is provided through the position corresponding to the mounting groove 1172 on the positioning wall 1812, and the projection of the mounting groove 1172 on the plane where the positioning wall 1812 is located is within the range surrounded by the avoidance groove 1814.

[0115] In fact, there are multiple installation slots 1172, some of which are arranged opposite to the positioning wall 1812, and the remaining installation slots 1172 are arranged offset from the positioning wall 1812. For the installation slots 1172 arranged opposite to the positioning wall 1812, after the corresponding installation member 1151 passes through the installation slot 1172, it continues to pass through the avoidance slot 1814 provided through the positioning wall 1812, and the plugging can be successfully completed.

[0116] It can be seen that the integrated heat pump 100 provided in this embodiment has the characteristics of convenient and quick installation of the right side plate 115 and a stable and reliable installation structure.

[0117] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
