Description

Technical Field

[0001] This utility model relates to the technical field of electrical control boxes, and more specifically, to a split-type electrical control box and a heat pump water heater. Background Technology

[0002] In existing technologies, electrical control boxes adopt an integrated design, with electronic components such as control boards and power modules sharing the same open space with wiring terminals. When installing or maintaining wiring terminals, the control board is fragile and easily damaged by accidental contact, leading to equipment failure and potentially causing safety hazards such as electric shock or short circuits. Utility Model Content

[0003] The first objective of this utility model is to provide a split-type electrical control box to solve the technical problem that the control board is easily damaged by accidental contact when installing or maintaining the wiring terminals.

[0004] The present invention provides a split-type electrical control box, including a box body, an isolation bracket, a first box cover, and a second box cover. The isolation bracket is disposed in the box body and divides the space inside the box body into a first space and a second space. A control board is disposed in the first space, and a terminal board is disposed in the second space. The first box cover is disposed on the opening of the first space, and the second box cover is disposed on the opening of the second space.

[0005] The split-type electrical control box provided by this utility model can produce the following beneficial effects:

[0006] The modular electrical control box provided by this utility model divides the internal space of the box into two independent spaces by setting an isolation bracket inside the box. Each space has an independent cover, which allows components in one space to be installed first and the corresponding cover to be closed, and then components in the other space to be installed and the corresponding cover to be closed. This effectively avoids accidental contact with the control board located in the other space when installing the terminal block or wiring. Alternatively, when maintenance is required on the components in one space, such as when maintaining the terminal block in the second space, only the cover of the second space (the second cover) needs to be opened, without opening the cover of the first space (the first cover). This effectively avoids accidental contact with the control board in the first space, and thus effectively avoids damage to the control board in the first space.

[0007] In other words, the split-type electrical control box provided by this utility model not only separates the control board and the wiring terminals into different functional areas in space, but also achieves physical isolation between the control board and the wiring terminals in space by setting up an isolation bracket and two box covers. This can fundamentally avoid the situation where the control board is accidentally touched and damaged during the installation and maintenance of the wiring terminals. Correspondingly, it also eliminates the risk and safety hazards of electric shock to the operator and short circuits, significantly improving the safety and convenience of operation for staff and users, and optimizing the after-sales maintenance experience.

[0008] Furthermore, a mounting bracket is detachably installed within the first space, and the mounting bracket is used to install the terminal block. With this configuration, workers can remove the mounting bracket before wiring, ensuring connection reliability and providing flexible wiring layout space, thus significantly improving the convenience of wiring operations. In other words, this design ensures electrical isolation safety while also considering the convenience needs of actual construction.

[0009] Furthermore, the isolation bracket is provided with a wiring channel, through which the wiring of the control board connected to the terminals in the second space passes.

[0010] Furthermore, an electrical control module is also provided in the second space, and the electrical control module includes a power transformer.

[0011] Furthermore, the first space is located below the housing, and the second space is located above the housing. In this configuration, the second space containing the wiring terminals is located at the top, which is not too low, thus facilitating operation.

[0012] Furthermore, a limiting groove is provided at the bottom of the box body, and the bottom edge of the first box cover is inserted into the limiting groove; the top of the first box cover is fixedly connected to the box body, and / or, the first box cover is fixedly connected to the outer edge of the isolation bracket. When installing the first box cover, first insert the bottom edge into the limiting groove of the box body, and then fix the top of the first box cover to the box cover and the isolation bracket.

[0013] Furthermore, the top edge of the first lid is provided with an outwardly extending first positioning flange, which has a positioning hole; the bottom edge of the second lid is provided with an outwardly extending second positioning flange, which has a positioning buckle inserted into the positioning hole; the top of the second lid is fixedly connected to the box body. With this configuration, after the first lid is installed, the first lid positions and limits the second lid during installation. Compared to the second lid being connected to the isolation bracket at its bottom edge, the second lid is directly installed above the first lid, effectively reducing the gap between the two lids and thus reducing the possibility of external dust and moisture entering the internal space of the box.

[0014] The second objective of this utility model is to provide a heat pump water machine to solve the technical problem that the control board is easily damaged by accidental contact during installation or maintenance of the wiring terminals.

[0015] The heat pump water heater provided by this utility model includes a housing and the aforementioned split-type electrical control box, wherein the split-type electrical control box is disposed within the housing. The heat pump water heater provided by this utility model possesses all the advantages of the aforementioned split-type electrical control box, and therefore will not be elaborated further here.

[0016] Furthermore, the split-type electrical control box is located behind the front panel of the enclosure, with its first and second covers facing the front panel. With this configuration, maintenance of the wiring terminals and other components is readily available; only the front panel of the enclosure and the second cover of the electrical control box need to be opened, making it very convenient.

[0017] Furthermore, one side of the box is rotatably mounted to one side panel of the housing via a hinge, and the other side of the box is fixedly connected to another side panel of the housing. With this configuration, when maintenance is required on the components behind the control box, it is only necessary to disconnect the fixed connection between the control box and the housing and rotate the control box to expose the components behind it, without having to remove the control box itself, which is very convenient.

[0039] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0040] This embodiment provides a split-type electrical control box 200, such as Figure 2 as well as Figure 5 and Figure 6 As shown, the split-type electrical control box 200 includes a box body 210, an isolation bracket 220, a first box cover 230, and a second box cover 240. The isolation bracket 220 is disposed inside the box body 210 and divides the space inside the box body 210 into a first space and a second space. A control board 260 is disposed in the first space, and a terminal board 280 is disposed in the second space. The first box cover 230 covers the opening of the first space, and the second box cover 240 covers the opening of the second space.

[0041] The split-type electrical control box 200 provided in this embodiment divides the space inside the box 210 into two independent spaces by setting an isolation bracket 220 inside the box body 210, and setting an independent box cover for each space. This allows the components in one space to be installed first and the corresponding box cover to be closed, and then the components in the other space to be installed and the corresponding box cover to be closed. This effectively avoids the situation where the terminal board 280 where the wiring terminals are located is accidentally touched or the control board 260 located in the other space is accidentally touched or touched during wiring. Alternatively, when it is necessary to maintain the components in one space, such as when maintaining the terminal board 280 in the second space, only the box cover of the second space, i.e., the second box cover 240, can be opened, without opening the box cover of the first space, i.e., the first box cover 230. This effectively avoids the situation where the control board 260 in the first space is accidentally touched or touched, and thus effectively avoids the situation where the control board 260 in the first space is damaged.

[0042] That is, the split-type electrical control box 200 provided in this embodiment not only makes the control board 260 and the wiring terminals belong to different functional areas in space, but also achieves physical isolation between the control board 260 and the wiring terminals in space by setting the isolation bracket 220 and two box covers. This can fundamentally avoid the situation where the control board 260 is accidentally touched and damaged when installing and maintaining the wiring terminals. Correspondingly, it also eliminates the risk and safety hazards of electric shock to the operator and short circuits, significantly improves the safety and convenience of operation for staff and users, and optimizes the after-sales maintenance experience.

[0043] Specifically, such as Figure 5 and Figure 8 As shown, in this embodiment, a mounting base 250 is detachably installed in the first space, and the mounting base 250 is used to install the terminal block 280. With this configuration, the worker can remove the mounting base 250 to operate when wiring, which not only ensures the reliability of the connection, but also provides the worker with flexible wiring layout space, thereby greatly improving the convenience of wiring operations. In other words, this design ensures electrical isolation safety while taking into account the convenience needs of actual construction.

[0044] More specifically, such as Figure 7 and Figure 8 As shown, in this embodiment, the fixing base 250 includes an angled mounting plate 251 and a transition plate 252, and the terminal plate 280 is mounted on the mounting plate 251; the end of the transition plate 252 away from the mounting plate 251 is provided with a fixing flange 253 extending in a direction away from the mounting plate 251, and the fixing flange 253 is fixedly connected to the bottom wall of the box body 210; the end of the mounting plate 251 away from the transition plate 252 is provided with an outwardly extending snap-fit ​​flange 254, and the side wall of the box body 210 is provided with a snap-fit ​​groove 212, and the snap-fit ​​flange 254 snaps into the snap-fit ​​groove 212. When installing the mounting base 250, first insert the snap-fit ​​flange 254 into the snap-fit ​​groove 212. At that time, the mounting plate 251 is parallel to the side wall of the box body 210. Then rotate the mounting base 250 until the mounting plate 251 is parallel to the bottom wall of the box body 210, and make the fixing flange 253 fit against the bottom wall of the box body 210. Finally, fix the fixing flange 253 to the bottom wall of the box body 210.

[0045] Preferably, the included angle between the mounting plate 251 and the transition plate 252 is greater than or equal to 90°. More preferably, the included angle between the two is greater than 90°. In this way, when the flange 253 and the bottom wall of the box 210 are connected and fixed by fasteners such as screws, the operating space is larger and more convenient.

[0046] In this embodiment, the terminal block 280 includes a power terminal block 281, a ground terminal 282, a signal terminal block 283, etc., wherein the signal terminal block 283 is mounted on the mounting base 250, while the power terminal block 281 and the ground terminal 282 are directly mounted on the bottom wall of the housing 210. Of course, in other embodiments of this application, the terminal block 280 is not limited to the above types, and the layout of each terminal block 280 is not limited to the above layout, as long as it is convenient for disassembly and maintenance.

[0047] Specifically, such as Figure 6 As shown, in this embodiment, the isolation bracket 220 is provided with a wire passage 221, through which the wires of the control board 260 connected to the terminals in the second space pass.

[0048] Furthermore, it should be noted that in this embodiment, the number of control boards 260 is not limited to one, but can be multiple. In addition to the control boards 260, the second space also contains an electrical control module, which includes a power transformer 270. Since both the control boards 260 and the power transformer 270 are not frequently touched during maintenance, placing them in the same space, but in a different space from the wiring terminals, provides effective protection for them.

[0049] In this embodiment, the height of the electrical control box is significantly greater than its width, and it is vertically oriented. The first space is located below the box body 210, and the second space is located above the box body 210. With this configuration, the second space containing the wiring terminals is located at the top, ensuring it is not too low and thus facilitating operation. Furthermore, before leaving the factory, the manufacturer can connect all the wiring terminals of the control board 260 at the bottom of the electrical control box to the power transformer 270. Before use, the user only needs to connect the upper power terminals. That is, when performing wiring operations in a home environment, the user only needs to open the second cover 240 of the electrical control box to complete the operation.

[0050] It should be noted that in other embodiments of this application, the layout of the second space and the first space is not limited to vertical distribution. For example, if the width of the box 210 is significantly greater than its height and the whole is in a horizontal position, the first space can also be located on the left side of the box 210, while the second space is located on the right side of the box 210.

[0051] Specifically, such as Figure 7 As shown, and in combination Figure 5 and Figure 9As shown, in this embodiment, a limiting groove 211 is provided at the bottom of the box body 210, and the bottom edge of the first box cover 230 is inserted into the limiting groove 211; the top of the first box cover 230 is fixedly connected to the outer edges of the box body 210 and the isolation bracket 220. When installing the first box cover 230, first insert the bottom edge into the limiting groove 211 of the box body 210, and then fix the top of the first box cover 230 to the box body 210 and the isolation bracket 220.

[0052] More specifically, such as Figure 7 As shown, in this embodiment, the outer edges of the two side walls of the box body 210 are respectively provided with a first fixing ear 213 and a second fixing ear 214 extending towards the first space. The outer edge of the isolation bracket 220 is centrally provided with a fifth fixing ear 222 extending towards the first space. The top of the first box cover 230 is fixed to the above three fixing ears by three screws. Of course, in other embodiments of this application, the first box cover 230 may only be fixedly connected to the box body 210, or only to the isolation bracket 220, as long as the reliability of the connection can be guaranteed.

[0053] In this embodiment, as Figure 4 As shown, the top edge of the first lid 230 is provided with an outwardly extending first positioning flange 231, and the first positioning flange 231 is provided with a positioning hole 232; the bottom edge of the second lid 240 is provided with an outwardly extending second positioning flange 241, and the second positioning flange 241 is provided with a positioning buckle 242, which is inserted into the positioning hole 232; the top of the second lid 240 is fixedly connected to the box body 210. With this configuration, after the first lid 230 is installed, during the installation of the second lid 240, the first lid 230 serves to position and limit the second lid 240. Compared to the second lid 240 having its bottom edge connected to the isolation bracket 220, the second lid 240 is directly installed above the first lid 230, which effectively reduces the gap between the two lids, thereby reducing the possibility of external dust and moisture entering the internal space of the box body 210.

[0054] Specifically, such as Figure 7 As shown, and in combination Figure 3 As shown, in this embodiment, the outer edges of the two side walls of the box body 210 are respectively provided with a third fixing ear 215 and a fourth fixing ear 216 extending toward the second space, and the top of the second box cover 240 is fixed to the above two fixing ears by two screws.

[0055] In summary, the split-type electrical control box 200 provided in this embodiment allows for the following installation steps: first, the control board 260 and power transformer 270 in the first space are installed, and then the first cover 230 is sealed; next, the terminal board 280 in the second space is installed, and finally the second cover 240 is sealed. During maintenance, such as when the user is wiring, only the second cover 240 needs to be removed, fundamentally solving the problem of accidentally touching the control board 260 during wiring. While ensuring basic functions, it significantly improves the safety performance of household electrical equipment installation and maintenance. Furthermore, the optimized layout can greatly reduce the difficulty of operation and maintenance time costs, taking into account both reliability and maintenance convenience, and fully meeting the needs of modern electrical equipment.

[0056] This embodiment also provides a heat pump water machine, such as Figure 1 As shown, the heat pump water heater includes a housing 100 and the aforementioned split-type electrical control box 200, which is disposed within the housing 100. The heat pump water heater provided in this embodiment has all the advantages of the aforementioned split-type electrical control box 200, and therefore will not be described in detail here.

[0057] Specifically, in this embodiment, the split-type electrical control box 200 is located behind the front panel of the enclosure 100, and the first cover 230 and the second cover 240 of the split-type electrical control box 200 face the front panel. With this arrangement, when maintenance is required on the wiring terminals, it is only necessary to open the front panel of the enclosure 100 and the second cover 240 of the electrical control box, which is very convenient.

[0058] Specifically, in this embodiment, one side of the box 210 is rotatably mounted to one side plate of the housing 100 via a hinge 201, and the other side of the box 210 is fixedly connected to another side plate of the housing 100. With this configuration, when maintenance is required on the components behind the control box, it is only necessary to disconnect the fixed connection between the control box and the housing 100 and rotate the control box to expose the components behind it, without having to remove the control box itself, which is very convenient.

[0059] More specifically, such as Figure 1 As shown, in this embodiment, the left side of the box body 210 is rotatably connected to the left side plate 130 of the box body 100 by three hinges 201 arranged vertically. The right side of the box body 210 is provided with two connecting ears 202 extending to the right, and two screws fix the two connecting ears 202 to the right side plate 140 of the box body 100 respectively.

[0060] In addition, such as Figure 2 As shown, and in combination Figure 7 and Figure 10As shown, the top cover plate 120 of the enclosure 100 is provided with a hook 121; the top of the box 210 is also provided with a hook 217, which has a first hook hole 218; the top of the second box 240 is also provided with a hook flange 243, which has a second hook hole 244. The box 210 and the second box cover 240 are respectively hooked to the hook 121 through the first hook hole 218 and the second hook hole 244. When installing the electrical control box 200 into the enclosure 100, the electrical control box 200 can be first hung on the top cover plate 120 of the enclosure 100 through the first hook hole 218 and the second hook hole 244, and then the hinge 201 and the fixing connecting ear 202 can be installed, which is very convenient.

[0061] Of course, in other embodiments of this application, the connection between the control box and the housing 100 is not limited to the above connection method. For example, the control box can also be rotatably connected to the right side plate 140 of the housing 100 via a pivot on the right side, fixedly connected to the left side plate 130 of the housing 100 on the left side, and not connected to the top cover plate 120 of the housing 100 on the top.

[0062] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
