[0002] At present, the heating system includes heat pump equipment. An air duct structure is provided inside the heat pump equipment, and a fan is provided in the air duct structure. When the fan fails, the fan needs to be removed for maintenance. First, the outer shell of the heat pump equipment needs to be completely disassembled to expose the air duct structure, and then the housing of the air duct structure needs to be disassembled along its height direction to remove the internal fan. In addition, if the air outlet and air inlet of the heat pump equipment are connected to the air duct, the air duct needs to be removed first before the outer shell of the heat pump equipment can be disassembled, resulting in troublesome maintenance operations. And limited by the installation environment, when the heat pump equipment is installed in a space with a small height, it is difficult to disassemble the air duct structure along the height direction.

[0048] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0049] Referring to Figure 1 and Figure 3 As shown, the heat pump device 1000 provided by the embodiment of the present utility model includes a box body 100, a cover plate 200 and a fan assembly 300. A cavity 110 is provided inside the box body 100. The box body 100 includes a peripheral wall, and an opening 111 is provided on the peripheral wall. The peripheral wall can be understood as the inner peripheral wall of the cavity 110, or can be understood as the outer peripheral wall of the box body 100. The opening 111 can be understood as being surrounded by the peripheral wall, or, alternatively, it can be understood that an opening 111 is provided on one side of the box body 100, and the opening 111 communicates with the cavity 110. The cover plate 200 is covered on the opening 111. The cover plate 200 and the opening 111 are located on the same side of the box body 100. The cover plate 200 can be opened or closed the opening 111. The cover plate 200 is detachably connected to the box body 100. Specifically, the cover plate 200 and the box body 100 can be connected together by structures such as buckles, screws or locks. The cover plate 200 can also be rotatably connected to the box body 100 through a hinge structure or a hinge structure. The fan assembly 300 is arranged in the cavity 110. Referring to Figure 1 and Figure 5 As shown, the fan assembly 300 includes a duct structure 310 and a fan body 320. The duct structure 310 includes a first housing 311 and a second housing 312. The second housing 312 is detachably connected to the first housing 311. A duct 313 is defined between the first housing 311 and the second housing 312. The fan body 320 is fixedly connected to the second housing 312. Specifically, the fan body 320 and the second housing 312 can be connected by means such as screws or buckles. The size and shape of the opening 111 can be adaptively set according to the shape of the second housing 312 and the fan body 320, ensuring that at least the fan body 320 and the second housing 312 can jointly enter or leave the cavity 110 through the opening 111. The opening 111 can specifically be a square, a rectangle or other irregular shapes.

[0050] Specifically, referring to Figure 1As shown, first define the axis X1. The axis X1 is parallel to the direction perpendicular to the opening 111. Therefore, the direction perpendicular to the opening 111 can be referenced by the axis X1, and the orientation of the opening 111 is the same as the direction of the axis X1. In the following embodiments, the direction of the axis X1 can be understood as the direction perpendicular to the opening 111.

[0051] Specifically, referring to Figure 1 As shown, the direction perpendicular to the opening 111 forms an angle with the height direction of the box body 100. It can also be understood that the axis X1 forms an angle with the height direction of the box body 100, and it can also be understood that the orientation of the opening 111 forms an angle with the height direction of the box body 100. The height direction of the box body 100 can be understood as Figure 1 the up and down direction in

[0052] In this embodiment, when it is necessary to remove the fan body 320, first remove the cover plate 200 to open the opening 111, so that the second housing 312 and the fan body 320 are exposed, and then it can be along Figure 1 the disassembly direction shown in Figure 1The reverse direction of the disassembly direction shown in the figure installs the second housing 312 directly into the box body 100 from the opening 111, and finally covers the cover plate 200 to complete the installation operation. In this embodiment, since the axis X1 is offset from the height direction of the box body 100, a certain operating space can be left. When the heat pump device 1000 is installed in an environment with a small height, the cover plate 200 can still be conveniently disassembled, and the second housing 312 and the fan body 320 can be taken out from the box body 100.

[0053] It should be noted that in this embodiment, only by disassembling the second housing 312 can the fan body 320 be disassembled. The first housing 311 can be fixedly installed in the cavity 110 of the box body 100 to ensure the stable connection between the air duct structure 310 and the box body 100.

[0054] Refer to Figure 3 and Figure 5 As shown, in some embodiments, the first housing 311 is provided with a first air inlet 3131 and a first air outlet 3132. The first air inlet 3131 faces the heat exchanger 500, the first air outlet 3132 is arranged upward, and the air duct 313 communicates the first air inlet 3131 and the first air outlet 3132. The upper side of the box body 100 is provided with a second air inlet 112 and a second air outlet 113. The second air inlet 112 communicates with the cavity 110, the second air outlet 113 is connected to the first air outlet 3132, and the second air inlet 112 and the second air outlet 113 are used to connect with the external air duct. The second air inlet 112 and the second air outlet 113 are located on the same side of the box body 100, which is convenient for connecting the air duct. The heat pump device 1000 includes a heat exchanger 500, and the fan assembly 300 covers one side of the heat exchanger 500, which is beneficial for wind gathering.

[0055] In some embodiments, the heat exchanger 500 is set as an evaporator. When the heat pump device 1000 is working, the heat exchanger 500 will absorb heat and release cold. The fan body 320 in the fan assembly 300 can generate negative pressure to suck the air from the external environment into the box body 100 through the second air inlet 112, so that the external air exchanges heat with the heat exchanger 500. The heat exchanger 500 can absorb the heat of the external air. After exchanging heat with the heat exchanger 500, the temperature of the air in the cavity 110 decreases, and the air in the cavity 110 flows out of the box body 100 through the air duct 313 of the air duct structure 310 from the second air outlet 113.

[0056] In some other embodiments, the heat exchanger 500 can also be set as a condenser or other types of heat exchangers, and the heat exchanger 500 can release heat when working.

[0057] Refer to Figure 1As shown, in some embodiments, when the heat pump device 1000 is installed in an environment with a small space in the up-down direction and also a small space in the left-right direction, and the rear side of the box body 100 leans against a wall or a mounting bracket and the rear side of the box body 100 is blocked by an object, at this time, the opening 111 can be arranged on the front side of the box body 100, and the cover plate 200 is also located on the front side of the box body 100. The second air inlet 112 and the second air outlet 113 are both located on the upper side of the box body 100. Since there is no object blocking the front side of the box body 100, the operation space is relatively sufficient. After removing the cover plate 200 at the front side position of the box body 100, the second housing 312 can be exposed, and then the second housing 312 can be removed along Figure 1 the disassembly direction of Figure 1 . Removing the second housing 312 can also remove the fan body 320. The disassembly steps are simple, facilitating maintenance or replacement operations. It can be understood that the axis X1 is arranged along the front-back direction and is perpendicular to the height direction of the box body 100, that is, the included angle between the axis X1 and the height direction of the box body 100 is a right angle. When disassembling the second housing 312, it can be understood that translating the second housing 312 forward can save operation space.

[0058] Referring to Figure 3 As shown, the fan body 320 includes a wind wheel 321 and a driving motor 322. The wind wheel 321 is located in the air duct 313, and the driving motor 322 can drive the wind wheel 321 to rotate. The wind wheel 321 is a centrifugal wind wheel and has an air inlet side and an air outlet side. Generally, the air inlet direction of the wind wheel 321 and the air outlet direction of the wind wheel 321 form an included angle with each other. Specifically, the wind wheel 321 has an axis X2, the wind wheel 321 rotates around the axis X2, the air inlet direction of the wind wheel 321 is parallel to the axis X2 of the wind wheel 321, the air outlet direction of the wind wheel 321 is arranged along the radial direction of the wind wheel 321, and the air outlet direction of the wind wheel 321 is substantially perpendicular to the axis X2. The air inlet side of the wind wheel 321 faces the first air inlet 3131, and the air outlet side of the wind wheel 321 faces the first air outlet 3132. When the wind wheel 321 rotates, the wind wheel 321 drives the air flow in the cavity 110 to first pass through the heat exchanger 500 and then enter the air duct 313 through the first air inlet 3131, and finally the air flow flows out from the first air outlet 3132. The flow direction of the air flow can refer to Figure 3 the arrow direction in Figure 3 .

[0059] In some embodiments, the axis X2 of the wind wheel 321 can be parallel to the height direction of the box body 100. It can be understood that the axis X2 of the wind wheel 321 is parallel to the up-down direction, and the wind wheel 321 is placed horizontally. At this time, the axis X1 can be arranged along the radial direction of the wind wheel 321. When taking out the second housing 312, the second housing 312 together with the horizontally placed wind wheel 321 can pass through the opening 111. The second air inlet 112 can be arranged on the upper side or the lower side of the box body 100, and the second air outlet 113 can be arranged on the left side or the right side of the box body 100.

[0060] In some embodiments, due to the structural characteristics of the wind wheel 321, generally speaking, the thickness of the wind wheel 321 along the axis X2 is less than the diameter of the wind wheel 321, and the shape of the second housing 312 is adapted to the wind wheel 321, which will cause the length of the second housing 312 along the axis of the wind wheel 321 to be less than the length of the second housing 312 along the direction perpendicular to the axis of the wind wheel 321, so as to Figure 1 illustrate by way of example. It can be understood that the length of the second housing 312 in the left-right direction is less than the length of the second housing 312 in the front-back direction or the up-down direction. Based on this, the axis X2 of the wind wheel 321 and the height direction of the box body 100 are set to form an angle with each other. It can be understood that the axis X2 of the wind wheel 321 forms an angle with the up-down direction, and the wind wheel 321 is inclined or vertically arranged. At the same time, the axis X1 and the axis X2 of the wind wheel 321 form an angle. When the second housing 312 is disassembled, the second housing 312 is taken out substantially along the radial direction of the wind wheel 321. Since the thickness of the wind wheel 321 in the axial direction is small, the space occupied by the second housing 312 in the left-right direction is small, which can save more operating space and is beneficial to taking out the second housing 312. It can also be understood that compared with the scheme where the axis X1 is parallel to the axis X2 of the wind wheel 321, the size requirement for the opening 111 in this embodiment is lower. Even if the opening 111 is small, the wind body and the second housing 312 can pass through together, which saves more space.

[0061] In some embodiments, referring to Figure 1 as shown, the axis X1 can be set perpendicular to the axis X2 of the wind wheel 321. At the same time, the axis X2 of the wind wheel 321 is perpendicular to the height direction of the box body 100. When the second housing 312 is disassembled, the second housing 312 is taken out along the radial direction of the wind wheel 321. Since the thickness of the wind wheel 321 is small, the space occupied by the second housing 312 in the left-right direction is small, which saves more operating space and is beneficial to taking out the second housing 312.

[0062] In some other embodiments, the axis X1 can be parallel to the axis X2 of the wind wheel 321. When the second housing 312 is taken out, it can be understood that the second housing 312 is taken out along the axis X2 of the wind wheel 321.

[0063] Referring to Figure 3 and Figure 5As shown, in some embodiments, the first housing 311 includes a first side plate 3111 and an air outlet nozzle 3112. The first side plate 3111 faces the heat exchanger 500. The first side plate 3111 extends in the up and down direction. The air outlet nozzle 3112 is connected to the side of the first side plate 3111 facing away from the heat exchanger 500. It can be understood that the air outlet nozzle 3112 is connected to the left side of the first side plate 3111, and the heat exchanger 500 is located on the right side of the first side plate 3111. The air outlet nozzle 3112 is a tubular structure, and the air outlet nozzle 3112 is used to guide the air flow in the air duct 313 to flow upward out of the second air outlet 113. The second housing 312 covers the side of the first side plate 3111 facing away from the heat exchanger 500. It can also be understood that the second housing 312 and the air outlet nozzle 3112 are respectively located on the left side of the first side plate 3111. The upper end of the second housing 312 is connected to the lower end of the air outlet nozzle 3112. The height of the second housing 312 is less than the height of the first housing 311. The second housing 312 is located below the air outlet nozzle 3112. It can also be understood that an installation position is defined between the air outlet nozzle 3112, the first side plate 3111 and the box body 100, and the second housing 312 is located in the installation position. Such a setting can make the height of the second housing 312 smaller, thereby reducing the size of the second housing 312 in the height direction. The height dimension of the opening 111 can also be set relatively small accordingly, making it easier for the second housing 312 to pass through the opening 111, facilitating the disassembly operation. When the second housing 312 is removed, the second housing 312 is not likely to interfere with other structures.

[0064] It should be noted that with reference to Figure 5 As shown, in some embodiments, the first air inlet 3131 is provided on the first side plate 3111. The first air inlet 3131 can be set as a circle, which is relatively matched with the shape of the air impeller 321. The axis of the first air inlet 3131 is parallel to the axis X2 of the air impeller 321. The first air outlet 3132 is formed at the upper end of the air outlet nozzle 3112. The first air outlet 3132 can be set as a circle to facilitate docking with the second air outlet 113. The air outlet side of the air impeller 321 faces the air outlet nozzle 3112. The air outlet nozzle 3112 can be understood as a horn-shaped structure. An air outlet channel is formed inside the air outlet nozzle 3112, and the cross-sectional area of the air outlet channel gradually increases from top to bottom, which can play a role in accelerating the air flow.

[0065] With reference to Figure 3 As shown, in some embodiments, the heat exchanger 500 extends in the up and down direction. The heat exchanger 500 divides the cavity 110 into a first cavity 114 and a second cavity 115. The first cavity 114 is communicated with the second air inlet 112, and the second cavity 115 is communicated with the second air outlet 113. The flow direction of the air flow can be referred to Figure 3In the direction of the arrow, the air in the first chamber 114 needs to pass through the heat exchanger 500 before entering the second chamber 115, which can avoid air leakage and ensure that the air entering the cabinet 100 is fully heat-exchanged with the heat exchanger 500 before flowing out of the cabinet 100. The heat pump device 1000 includes a compressor 700 and an electric control box 800. The compressor 700 is connected to the heat exchanger 500. The electric control box 800 is used to install electrical components or connection lines for controlling the compressor 700. The compressor 700 and the electric control box 800 are located in the first chamber 114, and the fan assembly 300 is located in the second chamber 115, which can make full use of the internal space of the cabinet 100 and is beneficial to the miniaturization of the heat pump device 1000. In addition, during operation, the compressor 700 and the electric control box 800 will generate heat, which can increase the temperature of the air in the second chamber 115. The heated air can be heat-exchanged with the heat exchanger 500, which is beneficial to increasing the temperature of the heat exchanger 500.

[0066] Referring to Figure 1 As shown, in some embodiments, the size and shape of the opening 111 can be set to allow components such as the heat exchanger 500, the compressor 700, and the electric control box 800 to enter or leave the cavity 110 through it. After removing the cover plate 200, components such as the heat exchanger 500, the compressor 700, and the electric control box 800 can be exposed, which facilitates maintenance operations on components such as the heat exchanger 500, the compressor 700, and the electric control box 800.

[0067] Referring to Figure 14 As shown, in some embodiments, the second housing 312 includes a volute 3121 and a second side plate 3122. The second side plate 3122 can be understood as a motor bracket. The fan body 320 is connected to the second side plate 3122. The volute 3121 and the wind wheel 321 are connected to the same side of the second side plate 3122. The volute 3121 and the wind wheel 321 are both located between the first side plate 3111 and the second side plate 3122. The volute 3121 is a plate structure that generally surrounds the wind wheel 321. It can be understood that the volute 3121 generally extends around the axis X2 of the wind wheel 321, and the volute 3121 extends along the axis X2 of the wind wheel 321. The side of the volute 3121 facing away from the second side plate 3122 is connected to the first side plate 3111. The upper end of the volute 3121 is connected to the lower end of the air outlet nozzle 3112. The volute 3121 mainly functions to guide air and divert air. The side of the volute 3121 close to the first side plate 3111 is open, which can be understood as forming an opening. The wind wheel 321 can be separated from the second housing 312 along the axis X2 of the wind wheel 321.

[0068] Specifically, referring to Figure 14As shown, the volute 3121 includes an arc section 3125 and a volute tongue section 3126 that are connected to each other. The arc section 3125 surrounds the outer periphery of the wind wheel 321. The arc section 3125 is arranged to extend approximately around the axis X2 of the wind wheel 321. The volute tongue section 3126 is connected to the upper end of the arc section 3125. The volute tongue section 3126 is connected to the air outlet nozzle 3112. The arc section 3125 can guide the air flow upward to the position of the volute tongue section 3126. The air outlet side of the wind wheel 321 faces the air outlet nozzle 3112. When the drive motor 322 drives the wind wheel 321 to rotate, the air flow flowing out from the air outlet side of the wind wheel 321 is guided by the arc section 3125 and the volute tongue section 3126 to the air outlet nozzle 3112, and finally the air flow flows out from the air outlet nozzle 3112 through the second air outlet 113.

[0069] In some embodiments, the first housing 311 and the second housing 312 can be made of plastic by an integral injection molding process, or the first housing 311 and the second housing 312 can also be made of a metal material by processes such as integral forming, bending, or welding.

[0070] In some embodiments, the volute 3121 can be made of a foam material, which can play a heat preservation role. In some embodiments, sheet metal can be added at the weak part of the foam thickness to strengthen the structural strength of the volute 3121.

[0071] It should be noted that since the air duct structure 310 is divided into the first housing 311 and the second housing 312, it is necessary to consider how to seal and connect the first housing 311 and the second housing 312. Based on this, referring to Figure 14 As shown, in some embodiments, a first seal 330 is provided between the volute 3121 and the first side plate 3111. The first seal 330 is arranged along the extending direction of the side wall of the volute 3121 close to the first side plate 3111. It can also be understood that the first seal 330 is arranged along the extending curve of the volute 3121 to ensure good sealing at the mating position between the volute 3121 and the first side plate 3111. It can be understood that the volute 3121 and the first side plate 3111 squeeze the first seal 330 to reduce the gap between the volute 3121 and the first side plate 3111. At the same time, a second seal 340 is provided between the volute 3121 and the air outlet nozzle 3112. The second seal 340 is arranged to extend along the axis X2 to ensure good sealing at the mating position between the volute 3121 and the air outlet nozzle 3112. It can be understood that the upper end of the volute 3121 and the lower end of the air outlet nozzle 3112 squeeze the second seal 340 to reduce the gap between the volute 3121 and the air outlet nozzle 3112. The first seal 330 and the second seal 340 can play a sealing role and relieve the air leakage phenomenon. The first seal 330 and the second seal 340 can be made of materials such as sponge, rubber, or silica gel to improve the sealing performance. The first seal 330 and the second seal 340 can be connected to the volute 3121 by means of pasting or screws.

[0072] It can be understood that when the space in the cavity 110 is small, the gap between the second housing 312 and the box body 100 is small, and it is not easy to apply force to the second housing 312 to remove the second housing 312 during the process of removing the second housing 312. Based on this, referring to Figure 12 and Figure 14 As shown, in some embodiments, the second housing 312 includes a third side plate 3123. The third side plate 3123 and the volute 3121 are respectively connected to the same side of the second side plate 3122. The third side plate 3123 extends along the height direction of the box body 100. The third side plate 3123 faces the cover plate 200. A handle portion 3124 is provided on the side of the third side plate 3123 facing the cover plate 200. It can be understood that the handle portion 3124 is located on the front side of the first housing 311. After the cover plate 200 is removed, the operator can immediately see the handle portion 3124. At this time, the handle portion 3124 can be held to pull the second housing 312 out of the box body 100. The handle portion 3124 can facilitate the operator to apply force to pull out the second housing 312. In some embodiments, the handle portion 3124 can be configured as a convex handle-like structure, which is convenient for the operator's palm to hold the handle portion 3124 and can facilitate the application of force. In order to save occupied space, the handle portion 3124 can also be configured as a groove, and the fingers can be inserted into the groove to facilitate the fingers to apply force to pull the second housing 312 out of the box body 100. In addition, the occupied space of the third side plate 3123 is small, which saves the internal space of the box body 100 relatively.

[0073] Referring to Figure 12As shown, on the basis of the above embodiments, a connecting plate 3010 is provided on one side of the first side plate 3111 close to the first housing 311. The connecting plate 3010 extends in the up and down direction. The connecting plate 3010 faces the third side plate 3123. It can be understood that the connecting plate 3010 is located at the rear side of the third side plate 3123. The connecting plate 3010 is mainly used to connect with the first side plate 3111. The first side plate 3111 and the connecting plate 3010 are connected by fasteners 3012, so as to fix and install the first housing 311 and the second housing 312 together. Specifically, the fasteners 3012 can be structures such as screws or rivets. Fastening holes can be provided on the connecting plate 3010, and the fastening holes can be threaded holes or rivet holes. In some embodiments, the first side plate 3111 and the connecting plate 3010 can achieve positioning and fitting through a positioning member 3011. Specifically, the positioning member 3011 can be a positioning pin. Both the first side plate 3111 and the connecting plate 3010 are provided with positioning holes. First, the positioning member 3011 is inserted into the positioning holes of the first side plate 3111 and the connecting plate 3010 to achieve positioning, and then the above-mentioned fasteners 3012 are fixedly installed, which can ensure that the fasteners 3012 are accurately aligned with the fastening holes of the connecting plate 3010. In some embodiments, in order to reduce the occupied space, the height of the connecting plate 3010 can be less than the height of the third side plate 3123, so as to reduce the size of the connecting plate 3010 in the up and down direction.

[0074] Refer to Figure 5 and Figure 6As shown, in some embodiments, a first plate body 350 is provided on the side of the air outlet 3112 away from the first side plate 3111. It can be understood that the first plate body 350 is connected to the left side of the air outlet 3112, the first plate body 350 is connected to the lower end of the air outlet nozzle 3112, the first plate body 350 is extended along the axis of the opening 111, and a second plate body 360 is provided at the upper end of the second shell 312. The second plate body 360 is extended along the axis of the opening 111, and a flange 351 is provided at the end of the first plate body 350 close to the opening 111. It can be understood that the flange 351 is located on the front side of the first plate body 350, and the flange 351 is inclined toward the side away from the second plate body 360. It can also be understood that the flange 351 is inclined to the left, and the flange 351 is formed by bending part of the structure at the front end of the first plate body 350 to the left. The second plate 360 ​​is located on the right side of the first plate 350. The cooperation between the first plate 350 and the second plate 360 ​​can limit the second shell 312 from deviating to the left, which plays a limiting role. The second shell 312 can also be kept pressing the first seal 330 to the right to improve the sealing effect. During the installation of the second shell 312, the first plate 350 needs to be inserted into the right side of the second plate 360. Since the flange 351 is tilted to the left, during the installation process, the first plate 350 can be against the surface of the flange 351. The flange 351 can guide the first plate 350 to enter the right side of the second plate 360 ​​and slide with the second plate 360. The flange 351 plays a guiding role, which can facilitate the installation operation.

[0075] In some embodiments, a third seal is provided between the first plate body 350 and the second plate body 360. The third seal extends along the length direction of the first plate body 350. The third seal can be connected to the side of the first plate body 350 close to the second plate body 360 by gluing or screws, or connected to the side of the second plate body 360 close to the first plate body 350. It can also be understood that the first plate body 350 and the second plate body 360 clamp the third seal, which can reduce the gap between the first plate body 350 and the second plate body 360, thereby sealing the air duct 313 inside the air duct structure 310. The third seal can play a sealing role. The third seal can be made of materials such as sponge, rubber or silicone to improve the sealing performance.

Refer to Figure 12 and Figure 13 As shown, after the second housing 312 and the first housing 311 are installed together, the horizontal section 382 of the third plate body 370 overlaps on the third plate body 370, so as to limit the highest position of the third plate body 370 to be higher than the highest position of the guide plate 380, which can avoid the misalignment of the second housing 312 and the first housing 311 in the up and down direction. In addition, the inclined section 381 of the guide plate 380 can abut against the third plate body 370, preventing the second housing 312 from moving backward, and avoiding the misalignment of the second housing 312 and the first housing 311 in the front and back direction.

In some embodiments, the guide rail 400 can be an L-shaped structure, and the guide rail 400 can support and limit the second shell 312.

[0080] In this embodiment, when the second housing 312 is removed along the axis of the opening 111, the second housing 312 slides along the guide rail 400, which can play a guiding role and facilitate the removal of the second housing 312. When installing the second housing 312, after the connecting structure 440 is aligned with the slide groove 430 of the guide rail 400, the second housing 312 can be directly pushed into the box body 100, which can facilitate the installation operation.

It can also be understood that the fourth plate body 411, the fifth plate body 421 and the sixth plate body 422 enclose a generally concave-shaped space. It can also be understood that the connection structure 440 is inserted between the fourth plate body 411 and the fifth plate body 421, which can limit the up-and-down movement of the second housing 312. The sixth plate body 422 is located on the left side of the connection structure 440, which can limit the leftward movement of the second housing 312, ensuring that the second housing 312 is closely attached to the first housing 311 on the right side. The guide rail 400 plays a supporting role and a limiting role for the second housing 312.

[0082] Referring to Figure 5 As shown, in some embodiments, the heat pump device 1000 includes a water receiving tray 900. The water receiving tray 900 is located in the cavity 110 of the box body 100. The chassis 600 is installed in the water receiving tray 900.

[0083] Referring to Figure 4As shown, on the basis of the above embodiments, the limiting portion 420 further includes a seventh plate body 423 and an eighth plate body 424. The seventh plate body 423 extends in the vertical direction, and the eighth plate body 424 extends in the horizontal direction. The lower end of the seventh plate body 423 is connected to the fifth plate body 421, and the upper end of the seventh plate body 423 is connected to the eighth plate body 424. Both the seventh plate body 423 and the eighth plate body 424 are located on the left side of the connecting structure 440, which can increase the contact area between the limiting portion 420 and the connecting structure 440. The supporting portion 410 includes a ninth plate body 412, a tenth plate body 413, and an eleventh plate body 414. The tenth plate body 413 extends in the horizontal direction and is located below the fourth plate body 411. The tenth plate body 413 abuts against the chassis 600.

[0084] In this embodiment, the guide rail 400 can be understood as being bent into a substantially bow-shaped structure. The guide rail 400 can be made by a multi-step bending process. Such a setting can make the contact area between the guide rail 400 and the connecting structure 440 larger, and the supporting and limiting effects on the second housing 312 are better. Since the guide rail 400 is composed of multiple plate bodies, the guide rail 400 can generate a certain amount of deformation, which can improve the buffer impact ability of the guide rail 400, and the structural strength of the guide rail 400 is also improved. In addition, since there is a certain distance between the fourth plate body 411 and the bottom wall of the chassis 600, and there is a distance between the fourth plate body 411 and the bottom wall of the water receiving tray 900, and the connecting structure 440 is located above the fourth plate body 411, it can be understood that the guide rail 400 holds up the second housing 312, so that there is a distance between the second housing 312 and the bottom wall of the chassis 600, and there is a distance between the second housing 312 and the bottom wall of the water receiving tray 900. The second housing 312 will not come into contact with the defrosting water in the water receiving tray 900, which plays a protective role for the second housing 312.

[0085] In some embodiments, the guide rail 400 is provided as a sheet metal part and is made by a bending process or a stamping process, which can facilitate the manufacture of the structure of the guide rail 400, and the sheet metal part has a high structural strength and a low cost.

[0086] Some embodiments of the present utility model further provide a heating system, which includes the heat pump device 1000 of the above embodiments. In some embodiments, the heating system further includes a water tank for storing water. A condenser is provided in the water tank, and the condenser is connected to the heat exchanger 500. The heat exchanger 500 is configured as an evaporator, and the condenser is disposed outside the box body 100 of the heat pump device 1000. During operation, the compressor 700 compresses the low-pressure and low-temperature gaseous refrigerant, and the low-pressure gaseous refrigerant becomes a high-pressure and high-temperature gaseous refrigerant. The high-pressure and high-temperature gaseous refrigerant enters the condenser and releases heat in the condenser. The heat is transferred to the water tank, raising the water temperature in the water tank. Then the gaseous refrigerant passes through the heat exchanger 500, and the heat exchanger 500 absorbs the heat from the external environment, converting the liquid refrigerant into a gaseous refrigerant. Finally, the gaseous refrigerant flows into the compressor 700 to complete a cycle of circulation.

[0087] It should be noted that in some other embodiments, the heat pump device 1000 may not include a water tank. The heat pump device 1000 is configured as a split heat pump, and the heat pump device 1000 can be connected to an external water tank.
