Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an outdoor unit. Background Technology

[0002] In existing outdoor units, the electrical control box is usually connected to the inside of the casing by screws. When maintenance is required on the pipes or other components inside the outdoor unit, the electrical control box usually needs to be removed after the casing is opened. This requires removing many screws on the electrical control box, which is not only cumbersome to disassemble and assemble, but also carries the risk of screw damage or loss, resulting in unstable installation of the electrical control box and abnormal noise during the operation of the outdoor unit.

[0003] Therefore, how to simplify the installation of the electrical control box and improve the efficiency of disassembly and assembly is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] The problem solved by this invention is that the electrical control box in existing outdoor units is cumbersome to disassemble and assemble.

[0005] To address the above problems, embodiments of the present invention provide an outdoor unit, which includes:

[0006] Back panel;

[0007] The front panel and the back panel are positioned opposite each other at a distance.

[0008] An electric heating bracket is located on the inside of the panel, and the electric heating bracket is provided with raised ribs;

[0009] The electrical control box has one side hinged to the back panel, and the other side is detachably connected to the electric heating bracket by screws. The electrical control box also has a locking hole that engages with the protruding rib.

[0010] The beneficial effects of the outdoor unit provided in this embodiment of the invention include:

[0011] 1. The control box is connected to the back panel via a hinge, avoiding the need for the control box to be directly connected to the back panel with screws. When maintenance is required on the internal pipes or other components of the outdoor unit, simply remove the screws connecting the control box to the panel, and then flip the control box around the hinge to expose the internal pipes or other components of the outdoor unit. This makes disassembly and assembly simple and efficient, avoids repeated disassembly and assembly of the control box, and improves the stability of the control box installation.

[0012] 2. The electrical control box is connected across the electric heating bracket and the back panel, which not only improves the installation stability of the electrical control box, but also improves the structural strength of the outdoor unit;

[0013] 3. During the assembly of the electrical control box onto the back panel and the electric heating bracket, the locking holes on the electrical control box first engage with the protruding ribs on the electric heating bracket. This serves as a pre-positioning mechanism, facilitating subsequent screw-driving operations, reducing assembly difficulty, and improving the stability of the electrical control box installation during the assembly process.

[0014] In an optional implementation, the backplate includes:

[0015] Back panel main body;

[0016] The back panel is vertically connected to the edge of the back panel body. One end of the hinge is connected to the back panel with screws, and the other end of the hinge is connected to the electrical control box with screws.

[0017] This avoids the hinges being directly screwed to the back panel body, reducing the number of screws on the back panel body and improving the aesthetics of the outdoor unit. In addition, the back panel can provide a larger installation area for the hinges, which is beneficial for stable installation of the hinges.

[0018] In an optional implementation, the electrical control box includes:

[0019] Support plate;

[0020] The box body is connected to the support plate, and the other end of the hinge is connected to the box body by screws.

[0021] In an optional implementation, when the control box is connected to the electric heating bracket, the support plate is perpendicular to the back plate body.

[0022] When the electrical control box is rotated to its furthest position relative to the electric heating bracket, the side of the box overlaps with the back panel, and the support plate is parallel to the main body of the back panel.

[0023] In this way, the rotation range of the control box is 90°, that is, between the support plate being perpendicular to the back plate body and the support plate being parallel to the back plate body. The electric heating bracket panel and the back side plate respectively act as limiting parts for the control box to rotate to the two extreme positions, ensuring that the rotation process of the control box will not interfere with other parts or occupy the internal space of the housing (the rotation movement area of ​​the control box is basically located on the outside of the housing). In an optional embodiment, the control box further includes:

[0024] A connecting plate is located on the side of the box body near the electric heating bracket. The connecting plate has a first screw hole, and the electric heating bracket has a second screw hole. The first screw hole and the second screw hole are connected by screws.

[0025] Thus, by adding a connecting plate to the support plate for screw connection with the electric heating bracket, the connecting plate and the electric heating bracket can be in close overlapping contact, improving the stability of the screw connection. In an optional embodiment, the electric heating bracket includes:

[0026] The main body of the bracket is located on the inside of the panel;

[0027] The bracket side plate is connected to the edge of the bracket body, and the second screw hole is opened on the bracket side plate.

[0028] This allows the bracket side plate to contact (overlap) with the connecting plate surface and be connected by screws, improving the stability of the electrical control box installation.

[0029] In an optional embodiment, the rib is provided on the side plate of the bracket, and the engaging hole is provided on the connecting plate.

[0030] In an optional implementation, the outdoor unit further includes:

[0031] The base plate includes a base plate body and an annular upright plate. The annular upright plate is vertically connected to the edge of the base plate body. The back plate body, back side plate, support body and support side plate are all supported on the base plate body and are located on the inner side of the annular upright plate.

[0032] This improves the positional accuracy of the back panel, back side panel, bracket body, and bracket side panel, thereby enhancing the installation accuracy of the electrical control box and preventing inaccurate resetting during the flipping process.

[0033] In an optional embodiment, a reinforcing plate is provided at the bottom of the support side plate, the reinforcing plate being parallel to the base plate body and connected to the base plate body by screws.

[0034] This increases the installation strength of the bracket side plate, making it sufficient to withstand the impact on the bracket side plate during the flipping of the electrical control box.

[0035] In an optional embodiment, the outdoor unit also includes a side panel, which is connected to the back panel, the bracket side panel and the annular vertical panel by screws, wherein a connecting plate is clamped between the side panel and the front panel.

[0036] In this way, the back panel, bracket side panel, and annular upright panel are all connected to the side panel, which can improve the positional accuracy of each panel, thereby improving the installation positional accuracy of the electrical control box; the connecting plate clamped between the side panel and the bracket side panel can further improve the stability of the electrical control box installation.

Detailed Implementation

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] It is worth noting that the terms "front," "back," "left," "right," "up," and "down" used in this embodiment refer to the outdoor unit under normal operating conditions and are also the terms commonly used by those skilled in the art. Figure 1 As indicated by the arrow in the center.

[0046] Please refer to Figure 1 This embodiment provides an outdoor unit 100, which includes a back panel 1, a front panel 3, a base plate 4, an electrical control box 2, fan blades 6, and an electric heating bracket 7.

[0047] The front panel 3 and the back panel 1 are spaced apart and opposite to each other. One side of the electrical control box 2 is hinged to the back panel 1 via a hinge 5. In this embodiment, two hinges 5 are connected to the electrical control box 2, and the two hinges 5 are spaced apart vertically. The other side of the electrical control box 2 is detachably connected to the electric heating bracket 7 via screws. In this way, the electrical control box 2 spans across the electric heating bracket 7 and the back panel 1, which not only improves the installation stability of the electrical control box 2, but also improves the structural strength of the outdoor unit 100.

[0048] More importantly, the control box 2 is connected to the back panel 1 via the hinge 5, avoiding the direct connection of the control box 2 to the back panel 1 via screws. When maintenance is required on the internal pipes or other components of the outdoor unit 100, it is only necessary to remove the screws connecting the control box 2 to the electric heating bracket 7, and then flip the control box 2 around the hinge 5 to expose the internal pipes or other components of the outdoor unit 100. The disassembly and assembly are simple and efficient, avoiding repeated disassembly and assembly of the control box 2 and improving the stability of the installation of the control box 2.

[0049] The outdoor unit 100 has a fan blade 6 inside, and a vent 31 is opened on the panel 3, with the fan blade 6 facing the vent 31.

[0050] Please see Figure 2 and Figure 3 The back panel 1 includes a back panel body 11 and a back side panel 12. The back side panel 12 is vertically connected to the edge of the back panel body 11. One end of the hinge 5 is connected to the back side panel 12 by screws, and the other end of the hinge 5 is connected to the electrical control box 2 by screws. In this way, the hinge 5 is avoided from being directly screwed to the back panel body 11, reducing the number of screws on the back panel body 11 and improving the aesthetics of the outdoor unit 100. Moreover, the back side panel 12 can provide a larger installation area for the hinge 5, which is conducive to the stable installation of the hinge 5.

[0051] The back panel body 11 and the back side panel 12 are integrally formed or formed by stamping from a single sheet of material to ensure the connection strength between the back panel body 11 and the back side panel 12.

[0052] Please see Figure 4 The electrical control box 2 includes a support plate 21 and a box body 22. The box body 22 is connected to the support plate 21, and the other end of the hinge 5 is connected to the box body 22 by screws. When the electrical control box 2 is connected to the electric heating bracket 7 (e.g.) Figure 1 As shown in the diagram, the support plate 21 is perpendicular to the back plate body 11; when the electrical control box 2 is flipped to its furthest position relative to the electric heating bracket 7 (as shown in the diagram), the support plate 21 is perpendicular to the back plate body 11; Figure 4 As shown in the diagram, the side of the box 22 overlaps with the back panel 12, and the support plate 21 is parallel to the back panel body 11. Thus, the rotation range of the control box 2 is 90°, that is, between the support plate 21 being perpendicular to the back panel body 11 and the support plate 21 being parallel to the back panel body 11. The electric heating bracket 7 and the back panel 12 respectively act as limiting parts for the control box 2 to rotate to the two extreme positions, ensuring that the rotation process of the control box 2 does not interfere with other parts or occupy the internal space of the housing (the rotation movement area of ​​the control box 2 is basically located outside the housing).

[0053] Please see Figures 4 to 6The electrical control box 2 also includes a connecting plate 23, which is located on the side of the box body 22 near the electric heating bracket 7. The connecting plate 23 has a first screw hole 231, and the electric heating bracket 7 has a second screw hole 75. The first screw hole 231 and the second screw hole 75 are connected by screws. By adding a connecting plate 23 to the support plate 21 for screw connection with the electric heating bracket 7, the connecting plate 23 and the electric heating bracket 7 can be tightly overlapped and contacted, improving the stability of the screw connection. The electric heating bracket 7 includes a bracket body 72 and a bracket side plate 73. The bracket body 72 is located inside the panel 3; the bracket side plate 73 is connected to the edge of the bracket body 72, and the second screw hole 75 is located on the bracket side plate 73. This allows the bracket side plate 73 to contact (overlap) with the connecting plate 23 and be connected by screws, improving the installation stability of the electrical control box 2.

[0054] The bracket side plate 73 is provided with a protruding rib 71, and the connecting plate 23 is provided with a locking hole 24, which engages with the protruding rib 71. In this way, during the assembly of the electrical control box 2 onto the back plate 1 and the electric heating bracket 7, the locking hole 24 on the electrical control box 2 engages with the protruding rib 71 on the electric heating bracket 7, which can play a role in pre-positioning, making it easier to perform subsequent screwing operations, reducing assembly difficulty, and improving the stability of the electrical control box 2 during the assembly process.

[0055] Please see Figure 1 The base plate 4 includes a base plate body 41 and an annular upright plate 42. The annular upright plate 42 is vertically connected to the edge of the base plate body 41. The back plate body 11, back side plate 12, bracket body 72, and bracket side plate 73 are all supported on the base plate body 41 and are located inside the annular upright plate 42. This improves the positional installation accuracy of the back plate body 11, back side plate 12, bracket body 72, and bracket side plate 73, thereby improving the installation accuracy of the electrical control box 2 and preventing inaccurate reset during the flipping process of the electrical control box 2.

[0056] A reinforcing plate 74 is provided at the bottom of the bracket side plate 73. The reinforcing plate 74 is parallel to the base plate body 41 and is connected to the base plate body 41 by screws. In this way, the installation strength of the bracket side plate 73 is improved, which is sufficient to withstand the impact on the bracket side plate 73 during the flipping of the electrical control box 2.

[0057] The outdoor unit 100 also includes a side panel (not shown in the figure), which is connected to the back panel 12, the bracket side panel 73, and the annular vertical plate 42 by screws. A connecting plate 23 is clamped between the side panel and the bracket side panel 73. In this way, the back panel 12, the bracket side panel 73, and the annular vertical plate 42 are all connected to the side panel, which improves the positional accuracy of each panel, thereby improving the installation positional accuracy of the electrical control box 2. The connecting plate 23 clamping between the side panel and the bracket side panel 73 further improves the installation stability of the electrical control box 2.

[0058] The beneficial effects of the outdoor unit 100 provided in this embodiment include:

[0059] 1. The electrical control box 2 is connected to the back plate 1 via the hinge 5, avoiding the direct connection of the electrical control box 2 to the back plate 1 via screws. When it is necessary to maintain the internal pipes or other components of the outdoor unit 100, it is only necessary to remove the screws connecting the electrical control box 2 and the electric heating bracket 7, and then flip the electrical control box 2 around the hinge 5 to expose the internal pipes or other components of the outdoor unit 100. The disassembly and assembly are simple and efficient, avoiding repeated disassembly and assembly of the electrical control box 2 and improving the stability of the electrical control box 2 installation.

[0060] 2. The electrical control box 2 is connected across the electric heating bracket 7 and the back plate 1, which not only improves the installation stability of the electrical control box 2, but also improves the connection strength of the shell;

[0061] 3. The rotation range of the electrical control box 2 is 90°, that is, between the support plate 21 being perpendicular to the back plate body 11 and the support plate 21 being parallel to the back plate body 11. The bracket side plate 73 and the back side plate 12 respectively act as limiting parts for the electrical control box 2 to rotate to the two extreme positions, so that the rotation process of the electrical control box 2 will not interfere with other parts or occupy the internal space of the shell.

[0062] 4. During the process of assembling the electrical control box 2 onto the back plate 1 and the electric heating bracket 7, the engaging hole 24 on the electrical control box 2 and the protruding rib 71 on the electric heating bracket 7 first engage with each other, which can play a role in pre-positioning, making it easier to perform subsequent screwing operations, reducing assembly difficulty, and improving the stability of the electrical control box 2 installation during the assembly process.

[0063] 5. A reinforcing plate 74 is provided at the bottom of the bracket side plate 73 used to connect the electrical control box 2, which improves the installation strength of the bracket side plate 73 and is sufficient to withstand the impact on the bracket side plate 73 during the flipping of the electrical control box 2.

[0064] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
