[0031] Please refer to Figure 1 , Figure 1 It is a partial structural diagram of a heat pump unit 100. The embodiment of the utility model provides a heat pump unit 100 including a heat pump unit body (not shown in the figure), a frame 10, a pre-installation structure 20 and an electrical box 30; the heat pump unit body is arranged on the frame 10, the electrical box 30 is arranged on the pre-installation structure 20, the electrical box 30 is suspended and installed on the frame 10 through the pre-installation structure 20, and the electrical box 30 and the heat pump unit body are electrically connected. Among them, the heat pump unit body can realize the function of the heat pump unit, and the electrical box realizes circuit control of the heat pump unit.

[0032] In the heat pump unit 100 of this embodiment, the electrical box 30 is suspended and installed on the frame 10 through the pre-installation structure 20. When arranged in this way, the occupation of the chassis space can be reduced and the utilization efficiency of the chassis space can be improved. At the same time, when the electrical box 30 is suspended and installed, its installation position is relatively high, which is convenient for wiring of the electrical box 30 and can also improve the waterproof performance of the electrical box 30. In addition, during installation, the pre-installation structure 20 can be pre-installed, which can achieve preliminary positioning, can improve the accuracy and efficiency of the installation of the electrical box 30, and is easy to install.

[0033] It is understandable that, according to user needs, other accessories can be arranged on the rack 10 to realize the functions of the heat pump unit 100 and meet customer needs.

[0034] Please refer to Figures 2 to 4 In one embodiment, the pre-installation structure 20 includes a pre-installation plate 22 and a first connecting member (not shown in the figure); the frame 10 includes a first mounting beam 12, a positioning groove 222 is opened on the pre-installation plate 22, the electrical box 30 is arranged on the pre-installation plate 22, and the pre-installation plate 22 is clamped on the first mounting beam 12 through the positioning groove 222. The pre-installation plate 22 is also connected to the first mounting beam 12 through the first connecting member, so that the electrical box 30 is suspended and installed on the first mounting beam 12.

[0035] During installation, the positioning groove 222 and the first mounting beam 12 are first positioned relative to each other, and then the pre-installed plate 22 and the first mounting beam 12 are fixedly connected by the first connecting member, so that the electrical box 30 can be suspended and installed on the first mounting beam 12. Due to the mutual positioning of the positioning groove 222 and the first mounting beam 12, the pre-installed plate 22 can be limited to move along the width direction of the positioning groove 222, but the pre-installed plate 22 can be adjusted along the length direction of the positioning groove 222, which facilitates the connection and fixation of the first connecting member. Through the above-mentioned structural setting, the installation accuracy and efficiency of the electrical box 30 are high. Among them, the first connecting member can be a screw or a bolt.

[0036] It is understandable that the rack 10 may also include other structures, for example, the rack 10 may be a frame structure, and the frame structure includes a first mounting beam 12. The heat pump unit body is mounted on the frame structure.

[0037] In one embodiment, the heat pump unit 100 further includes a positioning member 40, which is arranged on the pre-installed plate 22. A positioning hole 122 is provided on the first mounting beam 12. The positioning hole 122 cooperates with the positioning member 40 to position the pre-installed plate 22 and the first mounting beam 12 relative to each other. After the positioning groove 222 and the first mounting beam 12 are positioned relative to each other, the positioning member 40 and the positioning hole 122 are then matched, and finally the pre-installed plate 22 and the first mounting beam 12 are fixedly connected by the first connecting member. Among them, the positioning groove 222 and the first mounting beam 12 are used to limit the front and rear positions of the pre-installed plate 22, and the positioning member 40 and the positioning hole 122 are used to limit the left and right positions of the pre-installed plate 22. Among them, the length direction of the first mounting beam 12 is the left and right direction, and the horizontal width direction of the first mounting beam 12 is the front and rear direction. Through the above-mentioned structural setting, the pre-installed plate 22 is positioned twice, and then locked and fixed, which can further improve the installation accuracy and installation efficiency.

[0038] It is understandable that, according to the user's choice or needs, the positioning member 40 is arranged on the first mounting beam 12, and a positioning hole 122 is opened in the positioning groove 222, which can also achieve the above-mentioned effect, and will not be repeated here.

[0039] In one embodiment, the positioning member 40 is a positioning block, and the end of the pre-installed plate 22 is bent to form the positioning block, and the positioning hole 122 is a strip hole. By bending the end of the pre-installed plate 22 to form the positioning block, the connection strength between the positioning block and the pre-installed plate 22 can be improved, the processing is more convenient, and materials can be saved. Among them, the strip hole is located on the top surface of the first mounting beam 12. Since the positioning hole 122 is a strip hole, the cooperation between the positioning block and the positioning hole 122 also has a certain directionality, which is conducive to further improving the positioning accuracy and positioning efficiency.

[0040] In one embodiment, a guide portion 42 is provided at the end of the positioning block away from the electrical box 30. By providing the guide portion 42, when the positioning block and the positioning hole 122 are installed in coordination, the installation efficiency is higher.

[0041] In one embodiment, a first connection hole 224 is formed on the pre-installation plate 22, a second connection hole 124 is formed on the first mounting beam 12, and a first connection member is inserted through the first connection hole 224 and the second connection hole 124 to connect the pre-installation plate 22 and the first mounting beam 12. When the first connection member is connected to the first connection hole 224 and the second connection hole 124, the connection between the pre-installation plate 22 and the first mounting beam 12 is achieved, and the connection efficiency is high and the connection strength is good.

[0042] In one embodiment, the number of the first connecting holes 224 is three, the number of the second connecting holes 124 is three, and the number of the first connecting members is three. The number of the first connecting holes 224, the number of the second connecting holes 124, and the number of the first connecting members are equal and correspond one to one. The center lines of at least three of the first connecting holes 224 are connected to form a first triangle, and the center lines of at least three of the second connecting holes 124 are connected to form a second triangle, and the second triangle is congruent to the first triangle.

[0043] The connection between the centers of the three first connecting holes 224 forms a first triangle, and the connection between the centers of the three second connecting holes 124 forms a second triangle. When the three first connecting members are connected between the corresponding first connecting holes 224 and the second connecting holes 124, due to the stability of the triangle, the connection strength between the pre-installed plate 22 and the first mounting beam 12 is better, thereby improving the stability and seismic resistance of the electrical box 30.

[0044] It can be understood that the number of the first connection hole 224, the second connection hole 124 and the first connection member can be greater than three.

[0045] In one embodiment, the rack 10 further includes a second mounting beam 14 and a second connecting member (not shown in the figure), the first mounting beam 12 is arranged in the horizontal direction, the second mounting beam 14 is arranged in the vertical direction, a third connecting hole 32 is opened on the electrical box 30, a fourth connecting hole 142 is opened on the second mounting beam 14, and the second connecting member is passed through the third connecting hole 32 and the fourth connecting hole 142 to connect the electrical box 30 and the second mounting beam 14. The first connecting member and the second connecting member respectively fix the pre-installed plate 22 from different dimensions, which can further improve the stability and seismic resistance of the electrical box 30.

[0046] In one embodiment, the electrical box 30 and the pre-installed structure 20 are connected by welding, threading or riveting. When the electrical box 30 and the pre-installed structure 20 are connected by welding, the connection strength is high, the load-bearing weight is large, the seismic resistance is good, the stability and durability are good, the harsh working conditions can be adapted, and the reliability is high. When the electrical box 30 and the pre-installed structure 20 are connected by threading, the same electrical box 30 can be connected with different types of pre-installed plates 22, and it has good compatibility and interchangeability. When the electrical box 30 and the pre-installed structure 20 are connected by riveting, the installation efficiency is high.

[0047] In one embodiment, the electrical box 30 includes a box body 34, a wire sheath 36 and a cover plate 38, wherein the cover plate 38 is connected to the side of the box body 34, and the wire sheath 36 and the pre-installed structure 20 are connected to the bottom of the box body 34. The cover plate 38 can be connected to the box body 34 by means of screws or other structures. Electrical components and circuit layout are arranged in the box body 34, and the cover plate 38 has a protective effect on the electrical components and circuits in the box body 34. The wire sheath 36 facilitates the passage of the circuit. The box body 34 is suspended and installed on the first mounting beam 12 and the second mounting beam 14 through the pre-installed structure 20, so that it is also very convenient for the user to perform wiring operations through the wire sheath 36.

[0048] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
