All of the second abutting surfaces are parallel to the side surfaces of the electrical box housing extending in the vertical direction, and all of the second abutting surfaces abut against the corresponding side surfaces of the electrical box housing and are fixedly connected by at least one screw structure.

[0010] Optionally, in some embodiments of the present application, the electrical box housing further includes a housing main body having a receiving groove and a housing cover covering the notch of the receiving groove.

[0024] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of this application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.

[0026] In addition, the descriptions involving "first", "second", etc. in this application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] In one embodiment, as Figures 1 to 4As shown in the figure, an embodiment of the present application provides an electrical box 100, which includes an electrical box housing 110, two connecting plates 120, and electrical components (not shown) installed inside the electrical box housing 110. The two connecting plates 120 are symmetrically fixed on two opposite sides of the electrical box housing 110. All the connecting plates 120 are provided with a first connecting portion 121 having a first abutting surface. All the first abutting surfaces are parallel to the front surface of the electrical box housing 110, and all the first abutting surfaces abut against the corresponding side of the frame 210 of the heat pump device 1 and are tightly connected by at least one snap structure 130.

[0028] It can be understood that the electrical box 100 mentioned in the embodiment of the present application is mainly applied in the heat pump device 1 to realize the centralized installation and electrical protection of the main electrical components in the heat pump device 1. Therefore, the electrical components may include electronic components such as a variable frequency drive board, a main control board, a fan speed regulation module, and a reactor required for the operation of the heat pump device 1, so as to realize the overall regulation and corresponding function control of the heat pump device 1 through the electrical components in the electrical box 100. Generally speaking, the electrical box housing 110 may specifically be a cubic structure. In addition to including the opposite front and back surfaces, it also includes two opposite side surfaces (specifically, the left side surface and the right side surface) that both extend in the vertical direction, which are mainly used for the installation and fixation of the two connecting plates 120, and also includes two opposite side surfaces (specifically, the top side surface and the bottom side surface) that both extend in the horizontal direction. The above-mentioned two connecting plates 120 being symmetrically fixed on two opposite sides of the electrical box housing 110 may specifically mean that the two connecting plates 120 are respectively fixed on the corresponding side surfaces of the electrical box housing 110 by a detachable fixing method (such as snap connection) or a non-detachable fixing method (such as welding).

[0029] In addition, to ensure good heat dissipation when the electrical components in the electrical box housing 110 are working, the above-mentioned electrical box housing 110 may specifically be made of a metal material with good heat conduction function. Preferably, the electrical box housing 110 may specifically be an all-aluminum housing. In this way, while having good heat conduction function, the overall structure of the electrical box 100 can be made lighter.

[0030] In this way, through the above structural arrangement, when the user installs and fixes the electrical box 100 in the corresponding heat pump device 1, only by making the first abutting surface of the first connecting portion 121 of the connecting plates 120 on both sides abut against the corresponding side frame 210 of the heat pump device 1, and then through at least one snap structure 130 for snap connection, after the first connecting portions 121 of the connecting plates 120 on both sides are installed and fixed on the corresponding side frame 210 of the heat pump device 1, the installation and fixation of the electrical box 100 in the corresponding heat pump device 1 can be completed quickly and conveniently, without the need to align the screw mounting holes in the narrow space inside the heat pump device 1, and without the need to operate the screw mounting structure in the limited operable space, which provides great convenience for the user to install and maintain the corresponding structure.

[0031] In some examples, such as Figures 1 to 4 As shown, a preset vertical distance is provided between the bottom side of the electrical box housing 110 and the chassis 220 of the heat pump device 1. In this way, through the above structural arrangement, the electrical box 100 can be integrally suspended in the corresponding heat pump device 1. Compared with the traditional electrical box 100 placed near the chassis 220, this installation method in this example can further reduce the installation difficulty by avoiding the interference of the chassis 220 on its installation space. Further, the above preset vertical distance is 45% - 50% of the reference distance, and the reference distance is the vertical distance between the top side of the frame 210 of the heat pump device 1 and the chassis 220 of the heat pump device 1. In this way, through this parameter setting, while reducing the installation difficulty, the installation position of the electrical box 100 will not affect the load-bearing and transportation of the entire heat pump device 1 due to being too high.

[0032] In some examples, such as Figures 1 to 4 As shown, the above snap structure 130 may specifically include a card hole 131 and a hook 132. The card hole 131 is opened on the surface of the corresponding side frame 210 facing the first abutting surface, and the hook 132 protrudes from the corresponding first abutting surface, and the engaging direction of the hook 132 faces the chassis 220 of the heat pump device 1. In this way, through the above structural arrangement, the electrical box 100 can be quickly and conveniently installed and fixed in the corresponding heat pump device 1 by means of hanging and buckling installation.

[0033] In some examples, such as Figures 1 to 4As shown, between all the first abutting surfaces and the corresponding side of the frame 210 of the heat pump device 1, there is also a further fastening connection through at least one screw structure 140. In this way, through the above structural arrangement, the connection between the first connecting portion 121 and the corresponding side of the frame 210 can be made more firm. In addition, since the electrical box 100 has been preliminarily fixed by the snap structure, when installing the screw structure 140 in this example, there is no need to align the screw installation holes anymore. And since the positions for installing these screw structures 140 are the first connecting portions 121 of the connecting plate 120, rather than the electrical box housing 110, the operating space will not be affected by the structure of the electrical box housing 110.

[0034] In some examples, as Figures 1 to 4 shown, all the connecting plates 120 are also provided with second connecting portions 122 having second abutting surfaces. All the second abutting surfaces are parallel to the side surfaces of the electrical box housing 110 extending in the vertical direction, and all the second abutting surfaces abut against the corresponding side surfaces of the electrical box housing 110 and are fastened and connected through at least one screw structure 140. In this way, through the above structural arrangement, it can be ensured that all the connecting plates 120 are firmly fixed on the corresponding side surfaces of the electrical box housing 110.

[0035] In some examples, as Figures 1 to 4 shown, all the connecting plates 120 are also provided with third connecting portions 123. The third connecting portions 123 are L-shaped structures to transition and connect between the corresponding first connecting portions 121 and second connecting portions 122. In this way, through the structural arrangement of the third connecting portions 123, while effectively enhancing the connection strength of the connecting plates 120, corresponding avoidance spaces are formed between the two opposite sides of the electrical box housing 110 and the corresponding sides of the frame 210 to avoid the flip-open operation mentioned below.

[0036] In some examples, as Figures 1 to 4 shown, the electrical box housing 110 further includes a housing main body 111 having a receiving groove 1111 and a housing cover 112 covering the notch of the receiving groove 1111. One side of the housing cover 112 is hingedly connected to the outer edge along the notch through at least one hinge structure 113, and the other side of the housing cover 112 is locked and connected to the inner edge along the notch through at least one electrical cabinet lock 114. In this way, through the above structural arrangement, the flip-open operation of the electrical box housing 110 can be realized, so as to facilitate the installation and maintenance of the electrical components inside it. At the same time, through the structural arrangement of the electrical cabinet lock 114, its safety protection is taken into account.

[0037] It can be understood that the hinge structure 113 and the electrical cabinet lock 114 mentioned in this example can both adopt the common hinge structure 113 and electrical cabinet lock 114 on the market.

[0038] In some examples, such as Figure 4 and Figure 5 As shown, a water-retaining folding edge 1112 is convexly provided along the inner side of the notch, and the water-retaining folding edge 1112 is extended along the circumference of the notch. The water-retaining folding edge 1112 includes a first folding edge portion 11 and a second folding edge portion 12, the first folding edge portion 11 is parallel to the opening direction of the notch, the second folding edge portion 12 is connected to the first folding edge portion 11, and the second folding edge portion 12 and the first folding edge portion 11 are arranged at an angle of a preset angle. In this way, through the above-mentioned structural arrangement, when the electrical box cover is opened, the water-retaining folding edge 1112 can effectively prevent rainwater from entering the interior of the electrical box 100 (i.e., the accommodating groove 1111), and compared with an ordinary water retaining plate, the water-retaining folding edge 1112 in this example is double shielded and protected by the structural combination of the first folding edge portion 11 and the second folding edge portion 12, and its waterproof ability is stronger. Furthermore, the preset angle mentioned above may specifically be 140° to 160°, preferably 150°, so that the best waterproof effect can be achieved through this parameter setting.

[0039] In some examples, such as Figure 4 As shown, the side wall of the accommodating groove 1111 is also provided with at least one wiring port 1113, and the opening of each wiring port 1113 is arranged toward the chassis 220 of the heat pump device 1. Thus, through the above-mentioned structural arrangement, the electrical connection between the electrical components and the outside is achieved while ensuring that it has a strong waterproof performance.

[0040] In one embodiment, Figure 4 As shown, an embodiment of the present application provides a heat pump device 1, which includes a heat pump unit 300 and an electrical box 100, and the electrical components are electrically connected to the heat pump unit 300.

[0041] It is understandable that the structure and function of the electrical appliance box 100 in this embodiment are completely the same as the structure and function of the electrical appliance box 100 in the above-mentioned embodiment, and will not be described in detail here.

[0042] In this way, the heat pump device of the present application has the same technical effect as the electrical box 100 having the same structure and function as in the above-mentioned embodiment, and thus will not be described in detail here.

[0043] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the utility model concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
