Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioners, and in particular to an electrical box assembly and an air conditioner. Background Art

[0002] At present, the functions of air-conditioning outdoor units are increasing, which leads to an increase in the number of main boards and circuit components inside the electrical box. The layout of the existing air-conditioning outdoor unit electrical box is that the main boards and circuit components are flatly distributed inside the electrical box and placed in layers. When installing the upper main board, it is necessary to install partitions on the electrical box for layered installation. This layout is very inconvenient to install, and the wiring method between the upper and lower layers is also relatively messy. When maintaining the circuit of the lower main board of the electrical box, it is often necessary to disassemble the upper electrical components and circuits, which makes the operation complicated.

[0003] At present, the heat dissipation methods of the electrical box of the air conditioner outdoor unit are mainly air cooling and refrigerant cooling. Air cooling mainly involves opening heat dissipation holes and heat dissipation windows on the electrical box to use air flow to take away the heat. The heat dissipation effect of this method is proportional to the size and number of the holes, but the holes affect the sealing of the electrical box, resulting in limited air cooling. At present, the refrigerant heat dissipation method of the outdoor unit electrical box is mainly to assemble the radiator on the electrical components and the outside of the electrical box with the refrigerant heat dissipation pipe together, and the refrigerant takes away the heat from the radiator and the surface of the electrical box to achieve the purpose of heat dissipation. The limitation of this method is that the refrigerant heat dissipation pipe is currently installed on the outside of the electrical box, and the cooling is mainly aimed at the contact part of the radiator. The heat dissipation effect on other parts inside the electrical box is not obvious, and the efficiency is low.

[0004] Due to the technical problems in the prior art such as complex assembly of the air conditioner outdoor unit electrical box, messy wiring of the air conditioner outdoor unit electrical box, inconvenient maintenance of electrical components such as the lower main board of the air conditioner outdoor unit electrical box, poor sealing and heat dissipation effect, and low heat dissipation efficiency of the air conditioner outdoor unit electrical box, the present invention studies and designs an electrical box assembly and an air conditioner.

[0061] As Figures 1 - 8b shown, the present disclosure provides an electrical box assembly, which includes:

[0062] A main board 5, a main board fixing frame 2, and a main board fixing plate 3. The main board fixing plate 3 includes a fixing plate main body 3b. The main board 5 is fixed on the plate surface of the fixing plate main body 3b, and the plate surface includes a long side and a short side;

[0063] The motherboard fixing bracket 2 is provided with a guiding portion, and the guiding portion can guide the moving direction of the motherboard fixing plate 3, so that the moving direction of the motherboard fixing plate 3 is along the direction of the long side or along the direction of the short side, and the moving direction of the motherboard fixing plate 3 is its installation direction or disassembly direction.

[0064] Through the guiding portion provided on the motherboard fixing bracket, the present disclosure can guide the movement of the motherboard fixing plate towards the long side or the short side of the board surface of the fixing plate body, so as to effectively fix the motherboard fixing plate to the motherboard fixing bracket by means of insertion. Compared with the fixing method of the laminated motherboard fixing plate in the prior art, the structural form of the present disclosure can effectively complete the assembly and disassembly between the motherboard fixing plate and the motherboard fixing bracket by insertion, making the assembly of the electrical box more convenient and solving the problem of complex assembly of the electrical box of the outdoor unit of the air conditioner at present; through the independently pullable motherboard fixing plate, each motherboard can be maintained without removing other electrical components and their circuits during maintenance, achieving the purpose of convenient maintenance and solving the problem of inconvenience in maintaining electrical components such as the lower motherboard in the electrical box of the outdoor unit of the air conditioner at present.

[0065] The present disclosure simplifies the assembly process by vertically inserting the motherboard components into the slots and only fixing them with two screws at the top; optimizes the internal wiring of the electrical box through the orderly distribution of the motherboards and the wiring grooves on the motherboard fixing plate; makes each motherboard not need to remove other electrical components and their circuits during maintenance through the independently pullable motherboard fixing plate, achieving the purpose of convenient maintenance; enhances the airtightness of the electrical box, the heat dissipation effect and the heat dissipation efficiency by canceling the air-cooled heat dissipation holes and inserting the refrigerant heat dissipation pipes into the electrical box and distributing them among the motherboard gaps.

[0066] The main structure of the present disclosure (as Figure 1 shown) includes a limiting member 1, a motherboard fixing bracket 2, a motherboard fixing plate 3, an electrical box base body 4, a motherboard 5, a refrigerant heat dissipation pipe assembly 6 and a wiring installation plate 7.

[0067] In some embodiments, the guiding portion includes a first sliding groove 2a provided on the motherboard fixing bracket 2, and a first sliding rail 3a is provided on the motherboard fixing plate 3. The first sliding rail 3a can be clamped in the first sliding groove 2a and slide along the extending direction of the first sliding groove 2a, and the extending direction of the first sliding groove 2a is along the direction of the long side or along the direction of the short side;

[0068] Alternatively, the guiding portion includes a second sliding rail (not shown) provided on the main board fixing bracket 2, and a second sliding groove (not shown) is provided on the main board fixing plate 3. The second sliding rail (not shown) can be clamped in the second sliding groove (not shown) and slide along the extending direction of the second sliding groove (not shown), and the extending direction of the second sliding groove (not shown) is along the direction of the long side or the short side.

[0069] These are two different preferred structural forms of the guiding portion of the present disclosure. The first structural form is as Figures 1 - 4d , by providing a first sliding groove on the main board fixing bracket and simultaneously opening a first sliding rail on the main board fixing plate, the first sliding rail can be effectively clamped into the first sliding groove and slide along the extending direction of the first sliding groove, so as to realize the movement of assembling or disassembling the main board fixing plate. And the extending direction of the first sliding groove is along the long side direction or the short side direction of the board surface of the assembled main board, which enables the main board fixing plate to be inserted and pulled out along the long side or short side direction to complete the assembly and disassembly of the main board fixing plate. Compared with the prior art of stacked placement (the main board fixing plates are stacked in sequence along the thickness direction of the main board fixing plate), it can realize convenient disassembly and assembly, and is convenient for repairing the underlying main board, improving the disassembly and assembly efficiency and the repair efficiency.

[0070] Similarly, for the second structural form, a second sliding rail is opened on the main board fixing bracket, and correspondingly, a second sliding groove is opened on the main board fixing plate, so that the second sliding rail can be effectively clamped into the second sliding groove and slide along the extending direction of the second sliding groove, so as to realize the movement of assembling or disassembling the main board fixing plate. And the extending direction of the second sliding groove is along the long side direction or the short side direction of the board surface of the assembled main board, which enables the main board fixing plate to be inserted and pulled out along the long side or short side direction to complete the assembly and disassembly of the main board fixing plate. Compared with the prior art of stacked placement (the main board fixing plates are stacked in sequence along the thickness direction of the main board fixing plate), it can realize convenient disassembly and assembly, and is convenient for repairing the underlying main board, improving the disassembly and assembly efficiency and the repair efficiency.

[0071] The processing material of the main board fixing bracket 2 of the present disclosure is an injection molding material, and its main structure (as Figures 3a - 3c shown) includes a first sliding groove 2a, a first hole 2b (preferably a screw hole), a circuit baffle 2c, and a third sliding groove 2d (preferably an oval sliding groove). The first sliding groove 2a corresponds to the outer contour of the limiting member 1 and the outer contours of the sliding rails on both sides of the main board fixing plate 3 so that it can slide in the first sliding groove; the first hole 2b is used to fix the main board fixing plate and the main board fixing bracket; the main function of the circuit baffle 2c is to cooperate with the circuit channel on the main board fixing plate 3 for wire routing in the electrical box; the oval sliding groove cooperates with the third buckle 1e on the limiting member 1 so that the limiting member 1 can slide within a certain range.

[0072] The processing material of the main board fixing plate 3 of the present disclosure is an injection molding material, and its main structure (as Figures 4a - 4d shown) includes a first slide rail 3a (preferably a T-shaped slide rail), a fixing plate main body 3b, a wire fixing hook 3c, a second buckle 3d, a wire tie fixing hole 3e, and a mounting portion 3f (i.e., a limiting plate). The main function of the T-shaped slide rail is to enable the main board fixing plate 3 to slide up and down in the first chute of the main board fixing frame 2. At the same time, the T-shaped slide rail cooperates with the circuit baffle 2c of the main board fixing frame 2 to form a square wire routing groove for fixing and connecting the circuits between the main boards, achieving the effect of optimizing the internal wire routing of the electrical box; the main function of the fixing plate main body 3b is to fix the main board; the function of the wire fixing hook 3c is to fix the incoming and outgoing lines on the main board; the second buckle 3d cooperates with the rotating buckle (the first buckle 1c) on the limiting member 1 to drive the main board fixing plate to rotate synchronously around the axis of the rotating buckle; the function of the wire tie fixing hole 3e is to fix the passing lines in cooperation with a wire tie; the function of the mounting portion 3f is to fix the main board fixing plate 3 on the main board fixing frame 2 to achieve the fixation of the main board.

[0073] In some embodiments, when the first chute 2a is included, the extending direction of the first chute 2a is in the vertical direction; or, when a second chute (not shown) is included, the extending direction of the second chute (not shown) is in the vertical direction. This is the preferred extending direction of the first chute of the present disclosure. As Figure 1 shown, the internal structure of the electrical box can be seen. The main board fixing plate 3 is fixed by inserting it into the main board fixing frame in the inward direction, and this direction is preferably the vertical direction. Usually, the electrical box assembly is placed flat on the ground or a base with the opening facing up to facilitate the assembly of the main board fixing plate and the main board, the disassembly of the main board and the main board fixing plate, and the separate maintenance of the main board.

[0074] In some embodiments, when the first chute 2a is provided on the main board fixing frame 2, the electrical box assembly further includes a limiting member 1, and the limiting member 1 is also disposed in the first chute 2a and can limit the movement of the main board fixing plate 3 in the disassembly direction. The present disclosure can also limit the main board fixing plate in its disassembly direction through the setting of the limiting member, preventing the main board fixing plate from being directly disassembled and disengaged from the first chute.

[0075] The processing material of the limiting member 1 is an injection molding material, which mainly plays a role in restricting the rotation position of the main board. Its main structure (as Figures 2a - 2dAs shown, it includes an L-shaped slider 1a, an elastic limiting member 1b (preferably a limiting spring), a first buckle 1c (preferably a rotating buckle), a third fastener 1d (preferably a pin), and a third buckle 1e (preferably a pin). The main function of the L-shaped slider 1a is to cooperate with the third fastener 1d to limit the axial movement of the rotating buckle, and cooperate with the third buckle 1e to enable the L-shaped slider to slide within a certain range in the first chute of the main board fixing frame 2. The limiting spring mainly functions to reset the rotating buckle.

[0076] In some embodiments, the limiting member 1 includes a first buckle 1c, and the main board fixing plate 3 further includes a second buckle 3d. The first buckle 1c is located on the movement path of the second buckle 3d. When the main board fixing plate 3 moves along the disassembly direction, the first buckle 1c can block the second buckle 3d. This is the preferred structural form of the limiting member of the present disclosure. Through the setting of the first buckle and the second buckle provided on the main board fixing plate, the first buckle can effectively block the second buckle, thereby effectively limiting and stopping the main board fixing plate in the disassembly direction.

[0077] In some embodiments, the first buckle 1c has a rotation central axis, so that the first buckle 1c can rotate around the rotation central axis. The first buckle 1c includes a first arc portion, and the second buckle 3d includes a second arc portion. The second arc portion can be combined with the first arc portion. Through the guidance of the arc surface of the first arc portion, the second buckle 3d can also rotate around the rotation central axis, and then drive the first slide rail 3a of the main board fixing plate 3 to withdraw from the first chute 2a and flip around the rotation central axis. The present disclosure also enables the first buckle to rotate around the rotation central axis by providing the first buckle with a rotation central axis. The first arc portion of the first buckle is effectively engaged with the second arc portion of the second buckle, so that the second buckle can also rotate around the rotation central axis, effectively realizing the limitation of the main board fixing plate along the disassembly direction, but can rotate around the rotation center, so as to flip the main board fixing plate to Figure 7 a position (horizontal position) for effective maintenance, which is more convenient for maintenance. The main board fixing plate can be independently pulled out through the chute and the limiting buckle, making it convenient for maintenance.

[0078] In some embodiments, the limiting member 1 further includes a slider 1a, the slider 1a is clamped in the first chute 2a and can slide in the first chute 2a. A rotating shaft 1f is provided on the slider 1a, the first buckle 1c is clamped on the rotating shaft 1f, and the rotation center axis is located on the central axis of the rotating shaft 1f. This is a preferred structural form of the limiting member of the present disclosure. Through the arrangement of the slider, it can effectively slide in the first chute, and can slide a certain distance along the disassembly direction with the main board fixing plate. The rotating shaft 1f provided on the slider can effectively clamp the first buckle, so that the rotation center axis of the first buckle is located on the central axis of the rotating shaft, and the first buckle rotates around the rotating shaft.

[0079] The assembly process of the present disclosure is to first assemble the main board fixing plate to the first chute, and then assemble the slider of the limiting member to the first chute, so that the first buckle of the limiting member can effectively limit the disassembly direction of the main board fixing plate and prevent it from coming out during the working process and other situations.

[0080] In some embodiments, the limiting member 1 further includes an elastic limiting member 1b. The first buckle 1c includes an annular structure. The annular structure is sleeved on the outer periphery of the rotating shaft 1f, and the elastic limiting member 1b is sleeved between the rotating shaft 1f and the annular structure, and can generate an elastic restoring force on the torsion of the first buckle 1c. The present disclosure also includes an elastic limiting member in the limiting member, which can generate a damping restoring force on the rotation direction of the first buckle, so that the first buckle can return to the original position, which is convenient for the main board fixing plate to return to the position in the first chute after the main board repair is completed. The elastic limiting member is preferably a spring (preferably a torsion spring).

[0081] In some embodiments, a third fastener 1d is further included. The third fastener 1d can pass through the annular structure to fix the first buckle 1c to the rotating shaft 1f along the direction of the rotation center axis. The third fastener 1d is preferably a pin. The present disclosure also can fasten the first buckle to the rotating shaft through the arrangement of the third fastener, thereby fixing the first buckle to the slider and completing the assembly between the first buckle and the slider.

[0082] In some embodiments, the mainboard fixing frame 2 is further provided with a third slide groove 2d, the third slide groove 2d is connected with the first slide groove 2a, the limiting member 1 further includes a third buckle 1e, one end of the third buckle 1e is connected with the slider 1a, and the other end can extend into the third slide groove 2d, the third slide groove 2d can limit the third buckle 1e in its movement direction, so as to limit the movement of the limiting member 1 in the first slide groove 2a. The third buckle is preferably a second pin. The present disclosure can make the third buckle slide in the third slide groove through the third slide groove provided on the mainboard fixing frame and the third buckle provided on the limiting member, and can limit the third buckle along the assembly direction or disassembly direction of the mainboard fixing plate through the third slide groove, and limit the mainboard fixing plate from coming out while limiting the limiting member from coming out, so that the mainboard fixing plate can only rotate in this extreme position for maintenance, but cannot come out directly.

[0083] In some embodiments, the third slide groove 2d is a waist hole, and its length direction is along the movement direction of the mainboard fixing plate 3. This is the preferred structural form of the third slide groove of the present disclosure, and the waist hole can effectively accommodate and guide the movement of the third buckle, and limit the movement of the third buckle, and the third buckle is preferably a pin.

[0101] The present disclosure also provides an air conditioner, which includes the electrical box assembly described in any one of the preceding items.

[0102] After the vertical insertion type electrical box of the present disclosure is assembled as a whole, as Figure 1 shown, the electrical box base body 4 is a carrier for other components and mechanisms; the main board fixing frame 2 is fixed inside the electrical box base body 4 by screws; the limiting member 1 slides up and down in the first chute 2a of the main board fixing frame 2 through the L-shaped slider 1a, and the upper and lower sliding of the third buckle 1e in the third chute 2d (waist-shaped chute) controls the upper and lower limit positions of the main board fixing frame 2 rising and falling; the T-shaped slide rails (first slide rails 3a) at both ends of the main board fixing plate 3 slide up and down in the first chutes 2a of the two main board fixing frames 2 respectively. When the main board fixing plate 3 rises to the limit position, as Figure 7As shown, the second snap 3d and the first snap 1c (rotating snap) are engaged with each other and can rotate synchronously around the rotating snap; the main board 5 is embedded in the corresponding main board fixing plate 3 and moves synchronously with the main board fixing plate 3; the refrigerant heat dissipation tube assembly 6 is fixed to the electrical box base body 4 by screws.

The mounting part 3f fits with the upper end surface of the main board fixing frame 2, and the two parts are fixed together with screws, so as to achieve the effect of fixing the main board; the refrigerant flows into the refrigerant heat dissipation tube 6d through the pipe joint 6b on the refrigerant heat dissipation tube 6 assembly, flows through the entire refrigerant heat dissipation tube 6d, and dissipates heat inside the electrical box; finally, it flows out through the pipe joint 6b at the outlet position of the refrigerant heat dissipation tube assembly 6 to complete the heat dissipation process.

[0105] When it is necessary to maintain the main board wiring or remove the main board, first remove the screws fixing the main board fixing plate 3, lift the main board fixing plate 3 upward so that it slides upward along the first chute 2a of the main board fixing frame 2. When the second snap 3d on the main board fixing plate 3 is engaged with the first snap 1c (rotating snap) on the limiting member 1, the main board fixing plate 3 will drive the limiting member 1 to slide upward together until the third snap 1e on the limiting member 1 moves to the uppermost end of the third chute 2d on the main board fixing frame 2 and then stops sliding. At this time, the bottom end of the main board fixing plate has disengaged from the first chute 2a of the main board fixing frame 2. At this time, lay down the main board fixing plate 3 to make it in a lying state (as Figure 7 shown), and at this time, the main board and other maintenance work can be carried out. After completion, lift the main board and insert it back to the original position, and fix it with screws again to complete the maintenance work.
