[0041] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0042] In the related art, the box assembly around the heat pump equipment includes multiple panels, and the multiple panels are fixedly connected with each other by screws. Since the panels are heavy, it is difficult to move the panels, which makes it difficult to accurately align the screw holes between the multiple panels during assembly of the panels, and thus it is difficult to tighten the screws to fix the multiple panels.

[0043] Based on this, referring to Figure 1 The utility model embodiment provides a box assembly 1000, mainly adopts the structure of the hook 110 and the spigot 220, first temporarily position cooperation of two panels, then again screw realization fixed, can conveniently assemble operation. It needs to be explained that the box assembly 1000 can be used in heat pump equipment, refrigeration equipment or other electrical equipment.

[0044] Referring to Figure 1 The box assembly 1000 includes at least two panels, and the number of panels can also be two or more. The multiple panels are sequentially connected and surround a housing structure, which can play a protective role. The shape surrounded by the multiple panels can be square, circular, oval or other shapes. The panels can be sheet metal parts made by bending process.

[0045] Referring to Figure 1 In the following embodiments, for convenience of description, any two adjacent panels of the box assembly 1000 are divided into a first panel 100 and a second panel 200. For example, the first panel 100 can be one of a left panel, a right panel, a rear panel and a front panel, and the second panel 200 is adjacent to the first panel 100. In some embodiments, the box assembly 1000 further includes a top cover and a bottom plate. The bottom plate is located below the multiple panels, and the top cover is located above the multiple panels, thereby forming a closed housing structure. The bottom plate and the top cover can be connected to the multiple panels by fasteners such as buckles or screws.

[0046] Referring to Figure 3 The side edge of the first panel 100 is provided with a hook 110, and the side edge of the second panel 200 is provided with a spigot 220. When the first panel 100 and the second panel 200 are arranged adjacent to each other, the hook 110 of the first panel 100 is engaged with the spigot 220 of the second panel 200, and the two panels are temporarily fixed. Figure 2As shown, the second panel 200 is provided with an opening 210 and a slot 220 which are in communication with each other and are arranged in sequence from top to bottom on the side of the first panel 100. In the first direction, the maximum width of the opening 210 is greater than the maximum width of the slot 220, or in other words, the area of the opening 210 is greater than the area of the slot 220. The hook 110 can pass into the opening 210 and move downward into the slot 220. The first direction can be understood as the horizontal direction, and the first direction is perpendicular to the up-down direction. The hook 110 is used to be clamped and fixed with the slot 220. The size of the opening 210 is relatively large, and the opening 210 is mainly used to facilitate the hook 110 to pass in the horizontal direction and facilitate the alignment of the hook 110 with the opening 210. The size of the slot 220 is relatively small, and the slot 220 is mainly used to clamp and position the hook 110. The opening 210 and the slot 220 are arranged in sequence from top to bottom because after the first panel 100 is placed later, the first panel 100 can automatically enter the slot 220 under the action of gravity and rely on gravity to keep the hook 110 clamped with the slot 220, which is more labor-saving.

[0047] Referring to Figure 3 As shown, the first panel 100 is provided with a first screw hole 140, and referring to Figure 2 As shown, the second panel 200 is provided with a second screw hole 270, and the first screw hole 140 and the second screw hole 270 are used to cooperate with the screw to fix the first panel 100 and the second panel 200.

[0048] In the process of assembling the first panel 100 and the second panel 200, the position of the second panel 200 is fixed in advance, and then the first panel 100 is moved so that the hook 110 is aligned with the opening 210. Since the maximum width of the opening 210 is greater than the maximum width of the slot 220, the alignment of the hook 110 with the opening 210 is easier than directly aligning the first screw hole 140 of the first panel 100 with the second screw hole 270 of the second panel 200 in the related art. The hook 110 can be more easily entered into the opening 210. Then, the first panel 100 is placed down, and the first panel 100 moves downward under the action of gravity, and at the same time, the hook 110 moves downward into the slot 220 and is clamped and fixed with the slot 220. At this time, the first panel 100 and the second panel 200 are positioned, the first panel 100 cannot move downward relative to the second panel 200 or move in the horizontal direction, and the first screw hole 140 of the first panel 100 and the second screw hole 270 of the second panel 200 are just aligned. The screw for fixing the first panel 100 and the second panel 200 can be conveniently tightened, thereby improving the convenience of assembling the cabinet assembly 1000.

[0049] Referring to Figure 2As shown, in some embodiments, the opening 210 and the bayonet 220 are both substantially square-shaped, and the opening 210 and the bayonet 220 extend along the up-down direction.

[0050] Referring to Figure 2 As shown, in some embodiments, the inner wall of the opening 210 is provided with a first guide surface 230, which is located between the opening 210 and the bayonet 220. Since the width of the bayonet 220 is small, the first guide surface 230 mainly plays a guiding role, guiding the clasp 110 in the opening 210 to enter the bayonet 220 under the action of gravity, without the need to move the first panel 100 to align the clasp 110 with the bayonet 220, the operation is more convenient. Specifically, at the position of the first guide surface 230, the width of the opening 210 gradually decreases from top to bottom in the horizontal direction. It can be understood that the width of the opening 210 gradually narrows from top to bottom at the position of the first guide surface 230. When the clasp 110 in the opening 210 moves downward under the action of gravity, the lower side of the clasp 110 abuts against the first guide surface 230, and the first guide surface 230 can guide the clasp 110 to move downward into the bayonet 220, that is, the clasp 110 slides downward along the first guide surface 230 under the action of gravity, and the clasp 110 can be automatically aligned with and clamped into the bayonet 220, and the assembly personnel do not need to move the first panel 100 along the horizontal direction to adjust the position in order to align the clasp 110 with the bayonet 220. The present embodiment arranges the first guide surface 230 to make the assembly and cooperation of the clasp 110 and the bayonet 220 more smooth, and can further improve the convenience of assembly.

[0051] It can be understood that the first guide surface 230 can be provided as an inclined surface, referring to Figure 2 As shown, in some embodiments, the first guide surface 230 includes a first inclined surface 231 and a second inclined surface 232 oppositely arranged along a first direction, and the first inclined surface 231 and the second inclined surface 232 are respectively located on opposite sides of the inner wall of the opening 210. The first direction can be the left-right direction in Figure 4 the first inclined surface 231 and the second inclined surface 232 gradually decrease from top to bottom, and in the assembly process, when the clasp 110 penetrates into the opening 210 and moves downward, the lower side of the clasp 110 can abut against the first inclined surface 231, or the lower side of the clasp 110 can abut against the second inclined surface 232. Regardless of which inclined surface abuts, the first inclined surface 231 and the second inclined surface 232 will eventually guide the clasp 110 into the bayonet 220. In other embodiments, only the first inclined surface 231 or only the second inclined surface 232 can be arranged. In the present embodiment, the first inclined surface 231 and the second inclined surface 232 are flat surfaces, and in other embodiments, the first guide surface 230 can also be provided as an arc surface or other types of curved surfaces.

[0052] Referring to Figure 3As shown in some embodiments, the hook 110 can be configured as an L shape, including a transverse portion 111 and a longitudinal portion 112 connected to each other, the transverse portion 111 extending along the horizontal direction and connected to the first panel 100 at one end thereof along the horizontal direction, and the longitudinal portion 112 connected to the other end of the transverse portion 111 along the horizontal direction, the longitudinal portion 112 extending downward, the transverse portion 111 passing through the bayonet 220 and being fixedly connected thereto, at this time, the lower end of the longitudinal portion 112 is below the bayonet 220, and the side edge of the longitudinal portion 112 abuts against the inner side of the second panel 200, thereby limiting the movement of the first panel 100 relative to the second panel 200 along the horizontal direction. The side wall of the longitudinal portion 112 near the transverse portion 111 is provided with a second guide surface 1121, at the position of the second guide surface 1121, the width of the longitudinal portion 112 in the second direction gradually decreases from top to bottom, so as to guide the longitudinal portion 112 to pass through the bayonet 220 along the second direction, the second direction can be understood as a direction perpendicular to the bayonet 220 or the opening 210, the second direction is perpendicular to the first direction, and the second direction can be the front-back direction in Figure 4 .

[0053] It should be noted that the first guide surface 230 is used to guide the hook 110 to automatically adjust the position in the first direction to enter the bayonet 220, and the second guide surface 1121 is used to guide the longitudinal portion 112 to pass through the bayonet 220 along the second direction, thereby realizing the guiding function in two perpendicular directions and further improving the assembly convenience.

[0054] Referring to Figure 2 and Figure 3 As shown in some embodiments, along the up-down direction, the maximum length of the opening 210 is greater than the maximum length of the bayonet 220, and in addition, the maximum width of the opening 210 along the horizontal direction is greater than the maximum width of the bayonet 220, which can ensure that the area of the opening 210 is greater than the area of the bayonet 220, and at the same time, the maximum length of the hook 110 along the up-down direction is less than the sum of the maximum length of the opening 210 and the maximum length of the bayonet 220, which at least ensures that the hook 110 can pass through the opening 210 and the bayonet 220 along the horizontal direction, and the hook 110 can be fixedly connected with the bayonet 220. In some embodiments, the maximum length of the hook 110 along the up-down direction is less than the maximum length of the opening 210, which ensures that the hook 110 can pass through the opening 210 along the horizontal direction alone, and the maximum length of the hook 110 along the up-down direction is greater than the maximum length of the bayonet 220, which makes the displacement of the hook 110 from the opening 210 to the bayonet 220 smaller, and facilitates the quick entry of the hook 110 into the bayonet 220 to realize the fixed connection.

[0055] In some embodiments, the length of the transverse portion 111 in the up-down direction is greater than the length of the clamping opening 220, and when the transverse portion 111 is clamped and fixed with the clamping opening 220, part of the structure of the transverse portion 111 is located in the opening 210, and the distance between the upper end of the transverse portion 111 and the inner wall of the upper end of the clamping opening 220 is small, which can shorten the distance of the upward movement of the transverse portion 111 and ensure that the transverse portion 111 is not easily loosened upward. In other embodiments, when the transverse portion 111 is clamped and fixed with the clamping opening 220, the transverse portion 111 can also be completely located in the clamping opening 220.

[0056] Referring to Figure 1 In some embodiments, the number of clamping openings 220 and clamping hooks 110 is multiple, and the multiple clamping openings 220 and clamping hooks 110 are arranged in the up-down direction.

[0057] In some embodiments, the clamping hook 110 is arranged on the inner side of the first panel 100, so that the clamping hook 110 is not exposed to the outside and can be protected.

[0058] In some embodiments, the clamping hook 110 can be a folded edge structure and is processed by a sheet metal bending process.

[0059] It should be noted that when the box assembly 1000 is applied to the heat pump equipment 2000, since the heat pump equipment 2000 has heat preservation requirements, the air leakage of the box assembly 1000 is required to be small to avoid the influence of external air on the temperature inside the heat pump equipment 2000 and ensure the normal work of the heat pump equipment 2000, so it is necessary to consider improving the sealing performance of the box assembly 1000.

[0060] Based on this, referring to Figure 2 , Figure 3 and Figure 8As shown, in some embodiments, the second panel 200 is provided with a first step 240 near one side of the first panel 100, the first step 240 can also be understood as a bent plate structure, which can be processed by a bending process, the first step 240 has a first plane 241 and a second plane 242 perpendicular to each other, the first plane 241 and the second plane 242 can be understood as constituting a step surface, which is mainly used to achieve a sealing effect, the first panel 100 is provided with a flange 150 near one side of the first step 240, the flange 150 extends into the first plane 241 and the second plane 242, since the second plane 242 is used for sealing cooperation with the flange 150, therefore, in the horizontal direction, the length of the first plane 241 is less than the length of the second plane 242, thereby shortening the distance between the second plane 242 and the flange 150, the second plane 242 faces the inner side of the first panel 100, when the inner side of the first panel 100 is a plane, the second plane 242 can be parallel to the inner side of the first panel 100, the second plane 242 is provided with a first sealing element 500, when the hook 110 and the clamping opening 220 are clamped and fixed, the flange 150 abuts and tightly cooperates with the first sealing element 500, thereby achieving a sealing effect, which can seal the gap between the first panel 100 and the second panel 200, thereby reducing the air leakage of the box assembly 1000, the air outside is not easy to enter the inside of the heat pump equipment 2000 through the gap between the first panel 100 and the second panel 200. In this embodiment, the flange 150 and the first sealing element 500 can be understood as forming a first sealing surface.

[0061] It can be understood that the first sealing element 500 can be provided as a sponge, a rubber or other sealing material, which can improve the sealing effect.

[0062] Referring to Figure 2 and Figure 8As shown, in some embodiments, the second panel 200 is further provided with a second step 245, the second step 245 is connected with the first step 240, the second step 245 comprises a third plane 243 and a fourth plane 244 which are perpendicular to each other, the third plane 243 and the fourth plane 244 can be understood as constituting a step surface, the first step 240 and the second step 245 constitute two step surfaces, the first step 240 and the second step 245 can be processed by a continuous bending process, the third plane 243 connects the second plane 242 and the fourth plane 244, the third plane 243 is perpendicular to the second plane 242, the opening 210 and the bayonet 220 are opened on the fourth plane 244, the fourth plane 244 faces the first panel 100, the box assembly 1000 further comprises a first heat preservation piece 600, the first heat preservation piece 600 covers the inner side surface of the first panel 100 and has a heat preservation and insulation effect, the first heat preservation piece 600 is located between the first panel 100 and the fourth plane 244, and the third plane 243 abuts against the first heat preservation piece 600. In the embodiment, the third plane 243 and the first heat preservation piece 600 can be understood as forming a second sealing surface, the second sealing surface and the first sealing surface of the above-mentioned embodiment are perpendicular to each other, thereby forming double sealing, and the sealing effect can be further improved, so that the air outside is not easy to enter the inside of the heat pump equipment 2000 from the gap between the first panel 100 and the second panel 200.

[0063] In some embodiments, the first heat preservation piece 600 can be a foam piece, a sponge piece or other heat preservation materials, which can weaken the influence of the outside space on the temperature inside the heat pump equipment 2000.

[0064] With reference to Figure 7 As shown, the utility model embodiment further provides a heat pump equipment 2000, the heat pump equipment 2000 includes fan assembly 700, first heat exchanger 710, compressor 730, second heat exchanger 740 and the box assembly 1000 of above-mentioned embodiment, the inner chamber of first heat exchanger is divided into air inlet chamber and air outlet chamber with box assembly 1000, air inlet chamber is connected with air inlet pipe, air outlet chamber is connected with air outlet pipe, second heat exchanger 740 and compressor 730 are installed in air inlet chamber, fan assembly 700 is installed in air outlet chamber, second heat exchanger 710 is provided with the refrigerant pipeline for connecting compressor 730 and first heat exchanger 710, and second heat exchanger 710 is further provided with water flow pipeline for connecting water supply pipe. First heat exchanger 710 can be evaporator, and second heat exchanger 740 can be plate heat exchanger.

[0065] The heat pump device 2000 mainly releases energy by compressing refrigerant by the compressor 730. In the working process, the compressor 730 compresses the refrigerant in a low-temperature and low-pressure state and in a gaseous state into a high-temperature and high-pressure state. The refrigerant in the high-temperature and high-pressure state flows to the second heat exchanger 740 and releases heat. The heat is transferred to the water flow pipeline through the second heat exchanger 740, so as to heat the water in the water flow pipeline. Then, the hot water is transported out through the water supply pipe. When the refrigerant in the high-temperature and high-pressure state passes through the expansion valve or the throttling valve, the high-temperature and high-pressure liquid refrigerant becomes a low-temperature and low-pressure gas-liquid mixed state. Then, the low-temperature and low-pressure gas-liquid mixed state refrigerant passes through the first heat exchanger 710. The first heat exchanger 710 absorbs heat from the surrounding environment to vaporize the refrigerant. The refrigerant changes from a low-temperature and low-pressure liquid state to a low-temperature and low-pressure gaseous state. The low-temperature and low-pressure gaseous refrigerant returns to the compressor 730. The heat pump device 2000 can convert electrical energy into heat energy, so as to replace the traditional water heater that provides hot water by burning gas.

[0066] Referring to Figure 7 In some embodiments, the first panel 100 and the second panel 200 are located at the rear side of the heat pump device 2000, and the other two adjacent panels are divided into a third panel 300 and a fourth panel 400. The third panel 300 and the fourth panel 400 are located at the front side of the heat pump device 2000. The second panel 200, the first panel 100, the third panel 300, and the fourth panel 400 are sequentially connected along the circumference of the heat pump device 2000. Figure 9 Referring to Figure 10 The fourth panel 400 is provided with a second groove 410 near one end close to the second panel 200. The second groove 410 is provided with a third sealing piece 520. The second panel 200 is provided with a second flange 250 near one end close to the fourth panel 400. The second flange 250 abuts against the third sealing piece 520, so as to seal the gap between the second panel 200 and the fourth panel 400. In the embodiment, the sealing effect is mainly improved by arranging the first sealing piece 500 and the second sealing piece 510.

[0067] Referring to Figure 1As shown, in some embodiments, the inner side of the first panel 100 is provided with a first support 130 for fixedly mounting the first heat preservation member 600, and the box assembly 1000 further comprises a second heat preservation member 620, which can be a foam member, a sponge member or other heat preservation material, and the inner side of the second panel 200 is provided with a second support 260 for fixedly mounting the second heat preservation member 620. The first heat preservation member 600 covers the inner side of the first panel 100, and the second heat preservation member 620 covers the inner side of the second panel 200. When the box assembly 1000 is assembled, the first heat preservation member 600 and the second heat preservation member 620 wrap around the outer periphery of the heat pump device 2000, which can improve the heat preservation effect and weaken the influence of external air on the temperature of the internal structure of the heat pump device 2000. The first support 130 and the second support 260 can be sheet metal supports and can be connected to the first panel 100 and the second panel 200 respectively by fasteners or welding.

[0068] With reference to Figure 7 As shown, in some embodiments, a recess 720 is formed between the fan assembly 700 and the first heat exchanger 710. The size of the first panel 100 and the second panel 200 can be adjusted so that the abutment between the first panel 100 and the second panel 200 corresponds to the position of the recess 720, so that the clamping hook 110 is located in the recess 720. Since the clamping hook 110 is located on the inner side of the first panel 100, the clamping hook 110 will not interfere with the internal structure of the heat pump device 2000, and the clamping hook 110 will not affect the thickness of the first heat preservation member 600. If the clamping hook 110 is arranged at a position outside the recess 720, in order to give the clamping hook 110 space, the thickness of the first heat preservation member 600 at the local position may

[0069] As shown, in some embodiments, a recess 720 is formed between the fan assembly 700 and the first heat exchanger 710. The size of the first panel 100 and the second panel 200 can be adjusted so that the abutment between the first panel 100 and the second panel 200 corresponds to the position of the recess 720, so that the clamping hook 110 is located in the recess 720. Since the clamping hook 110 is located on the inner side of the first panel 100, the clamping hook 110 will not interfere with the internal structure of the heat pump device 2000, and the clamping hook 110 will not affect the thickness of the first heat preservation member 600. If the clamping hook 110 is arranged at a position outside the recess 720, in order to give the clamping hook 110 space, the thickness of the first heat preservation member 600 at the local position may Figure 11As shown, in the related art, a rear panel 1 with a large volume is directly arranged on the rear side of the internal structure of the heat pump equipment. Due to the large weight of the rear panel 1, a crane needs to be used to lift the rear panel 1 to complete the assembly, which is high in cost. In addition, the front end of the rear panel 1 is provided with a flange 2 for connecting with the front panel. When the rear panel 1 is sleeved on the rear side of the internal structure of the heat pump equipment, the flange 2 needs to be pried open in the horizontal direction to the two sides to avoid interference between the flange 2 and the internal structure of the heat pump equipment, which will cause inconvenient assembly operation.

[0070] In order to solve the technical problems in the related art, in some embodiments of the utility model, the first panel 100 and the second panel 200 are configured as L-shaped and can be made by sheet metal bending process. The first panel 100 is located at the right rear side of the internal structure of the heat pump equipment 2000, and the second panel 200 is located at the left rear side of the internal structure of the heat pump equipment 2000. This embodiment can be understood as dividing the above-mentioned rear panel into the first panel 100 and the second panel 200, which can reduce the weight of the panel moved at one time. The weight of the single first panel 100 or the second panel 200 is small, and it is easy to move. The crane does not need to be used, and the cost can be reduced. In addition, the first panel 100 covers the right rear side of the internal structure of the heat pump equipment 2000, and the second panel 200 covers the right rear side of the internal structure of the heat pump equipment 2000. Compared with the scheme of arranging three panels on the left side, the rear side and the right side of the internal structure of the heat pump equipment 2000, the number of panels in this embodiment is smaller, and the gap between the multiple panels can be reduced to improve the sealing performance.

[0071] In the process of assembling the box assembly 1000, the second panel 200 is moved first, and the second panel 200 is assembled with the internal structure of the heat pump equipment 2000 from left to right and can be fixedly connected by screws and the like. Then, the first panel 100 is moved from rear to front, so that the clamping hook 110 of the first panel 100 enters the opening 210, and then the first panel 100 is lowered. Under the action of gravity, the first panel 100 moves downward, and the clamping hook 110 also enters the clamping opening 220 downward to realize clamping and fixing. Then, the screws connecting the first panel 100 and the second panel 200 can be tightened to fix the first panel 100 and the second panel 200 together. In this process, the flange does not need to be pried open to the two sides as in the related art, and the assembly operation can be facilitated. Finally, the third panel 300 and the fourth panel 400 are assembled.

[0072] In other embodiments, the first panel 100 and the second panel 200 can also be configured as a circular arc shape, an elliptical shape or other arc shape, which is matched with the shape of the internal structure of the heat pump equipment 2000.
