Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a pull-out electrical control box structure and an air conditioner. Background Technology

[0002] Currently, in commercially available air conditioning units (such as modular units), the electrical control box is typically placed vertically and fixedly in the lower space within the casing. However, modular units usually have limited casing height, and due to their numerous functional requirements, a vertically positioned design often necessitates a double-layered inverter electrical control box, resulting in the control box occupying a significant amount of lower space within the casing in terms of height (thickness). Furthermore, the fixed electrical control box is inconvenient to install and remove, affecting the production, assembly, and after-sales maintenance of the modular unit. Additionally, traditional modular units also house components such as compressors, air separators, and oil separators in the lower space within the casing, causing the large electrical control box to obstruct these components in terms of height (thickness), further hindering production, assembly, and after-sales maintenance. Moreover, the varying heights of components such as compressors, air separators, and oil separators lead to wasted space when these components are placed in the lower space within the casing.

[0003] In summary, how to provide an electrical control box structure that is easy to disassemble and maintain and avoids occupying a large amount of vertical installation space, so as to avoid the electrical control box obstructing components and facilitate the production, assembly and after-sales maintenance of air conditioners, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] This invention proposes a pull-out electrical control box structure and an air conditioner to solve the technical problem in the prior art that the lack of an electrical control box structure that is easy to disassemble and maintain and avoids occupying a large amount of vertical installation space makes it difficult to avoid the electrical control box obstructing components, which is detrimental to the production, assembly and after-sales maintenance of the air conditioner.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] This invention provides a pull-out electrical control box structure, comprising:

[0007] The bottom shell is used to connect to a fixed object. The two axial ends of the bottom shell are an open end and a closed end, respectively. The inner wall of the closed end is provided with a hinge seat and several reset parts.

[0008] A flip-top is hinged to a hinge seat. The end of the flip-top away from the hinge seat is provided with a first mating part, and the middle of the flip-top is provided with a second mating part.

[0009] A pull-out box, movably installed inside the bottom shell and connected to the reset piece, is used to house electrical components;

[0010] The latch is connected to the axial end of the pull-out box facing the closed end and matches the flip latch;

[0011] When the pull-out box is pushed along the bottom shell near the closed end, the latch is pushed up and passes over the first mating part, so that the latch is self-locked to the inside of the first mating part under the restoring action of the reset member;

[0012] When the pull-out box is pushed along the bottom shell near the closed end while in the self-locking state, the latch pushes up the second mating part, so that the latch disengages from the flip-top and unlocks under the restoring action of the reset member.

[0013] Preferably, the flap includes:

[0014] snap-on panels;

[0015] The hinge is located at one axial end of the buckle plate and is hinged to the hinge seat.

[0016] The first mating part is located at the other end of the axial direction of the buckle plate opposite the hinge part;

[0017] The second mating part is located in the middle of the buckle plate near the first mating part;

[0018] The pull-out box has a fixed seat at one axial end, and a latch is connected to the fixed seat.

[0019] Preferably, the first mating part is a fastening part that bends from the other end of the buckle plate toward the bottom wall of the bottom shell, and the two ends of the fastening part extend out of the axial sides of the buckle plate respectively. A pair of second mating parts are provided, and the pair of second mating parts are respectively connected to the ends of the corresponding parts of the fastening parts that extend out of the buckle plate toward the joint. The second mating part is an inclined plate that extends obliquely from the end of the fastening part in a direction away from the fastening part.

[0020] Preferably, the latch includes a straight section connected to the fixed base and bent sections respectively connected to both ends of the straight section and arranged facing each other. The bent section includes a connecting part connected to the straight section and a third mating part connected to the end of the connecting part away from the straight section and matching the fastening part and the inclined plate. The straight section, the connecting part and the third mating part constitute a C-shaped latch.

[0021] When the pull-out box is pushed along the bottom shell near the closed end and the reset member is compressed, the third mating part is lifted and passes over the fastening part, so that the latch is self-locked to the inside of the fastening part under the restoring action of the reset member;

[0022] When the pull-out box is pushed along the bottom shell near the closed end and the reset component is compressed while the latch is in the self-locking state, the third mating part lifts the inclined plate so that the latch disengages from the flip-top under the restoring action of the reset component.

[0023] Preferably, the hinged base includes:

[0024] A support plate is installed on the inner wall of the closed end;

[0025] A pair of bearings are spaced apart on the side of the support plate facing the open end;

[0026] The hinge shaft is fixedly mounted on a pair of bearings;

[0027] The hinge part is a bushing that is hinged to the hinge shaft.

[0028] Preferably, the end of the bushing away from the first mating part is provided with a limiting right angle. The limiting right angle, by cooperating with the inner wall of the closed end, limits the flipping stroke range of the hinge seat to between a straight posture parallel to the bottom wall of the bottom shell and an upward flipping posture tilted and flipped near the top opening of the bottom shell.

[0029] Preferably, the fixing base is a pipe clamp installed at one axial end of the pull-out box, and the straight section is tubular and fixedly installed on the pipe clamp.

[0030] Preferably, the inner wall of at least one side of the bottom shell is provided with a guide structure, and the outer wall of at least one side of the pull-out box is provided with a sliding structure that cooperates with the guide structure.

[0031] Preferably, the reset element is a reset spring connected between the inner wall of the closed end facing the open end and the axial end of the pull-out box facing the closed end.

[0032] The present invention also provides an air conditioner, including an air conditioning unit and the above-mentioned pull-out electrical control box structure. The bottom shell is installed on a fixed object inside the casing of the air conditioning unit, with the open end facing the outside of the casing. When the latch is unlocked, the pull-out box can extend or be pulled out from the open end along the bottom shell away from the closed end.

[0033] Preferably, the interior of the housing is divided into an upper space and a lower space by a shelf located in the middle of the housing, and the pull-out electrical control box structure is located at the bottom of the upper space on the back of the shelf and placed in the lower space.

[0034] Preferably, the shelf has a hollow structure, and a water receiving tray is embedded in the hollow structure. The top edge of the bottom shell is installed on the bottom perimeter of the hollow structure. The water receiving tray serves as the top cover of the pull-out electrical control box structure, covering the top opening of the bottom shell and forming a closed space with the bottom shell and the machine housing to enclose the pull-out box.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The pull-out electrical control box structure provided by this invention allows for quick assembly and disassembly of the pull-out box and its internal electrical components from the bottom shell, facilitating the production, assembly, and after-sales maintenance of the electrical control box. Furthermore, it allows the bottom shell and pull-out box to be placed horizontally at the top of the middle or lower space within the air conditioning unit's casing. This enables a single-layer structure in the vertical direction for the bottom shell and pull-out box, replacing the traditional double-layer layout of a vertical electrical control box. This fully utilizes the significant amount of wasted horizontal space within the casing of traditional air conditioners for installing the electrical control box structure. This also frees up a significant amount of height space in the lower part of the modular unit's casing for installing the vertical electrical control box. Since the oil and gas separators in air conditioners typically have a small vertical dimension, they can be compactly and stacked in the lower part of the casing. This avoids the horizontal bottom shell and pull-out box located in the middle or lower part of the casing from obstructing the oil and gas separator components in the lower part, thus facilitating the production, assembly, and after-sales maintenance of the modular unit, improving the unit's space utilization, and reducing the unit's maintenance costs.

[0066] To make the technical problem to be solved, the technical solution and the beneficial effects of the present invention clearer, the following description is provided in conjunction with the appendix. Figure 1-20 The present invention will be further described in detail below with reference to the embodiments.

[0067] Please refer to the following: Figure 1-20 The pull-out electrical control box structure provided by the present invention includes:

[0068] The bottom shell 1 is used to connect with a fixed object. The two axial ends of the bottom shell 1 are an open end 11 and a closed end 12, respectively. The inner wall of the closed end 12 facing the open end 11 is provided with a hinge seat 2 and several reset parts 3.

[0069] Flip buckle 4 is hinged to hinge seat 2. The end of flip buckle 4 away from hinge seat 2 is provided with a first mating part 43. The middle part of the flip buckle 4 between the hinge point of flip buckle 4 and hinge seat 2 and the first mating part 43 is provided with a second mating part 44.

[0070] The pull-out box 5 is movably installed inside the bottom shell 1 and connected to the reset piece 3, and is used to accommodate electrical components.

[0071] Lock 6 is connected to one axial end of the pull-out box 5 facing the closed end 12, and lock 6 matches the flip 4;

[0072] When the user pushes the pull-out box 5 along the bottom shell 1 near the closed end 12, it causes the latch 6 to be lifted and pass over the first mating part 43, while compressing the reset part 3, so that the latch 6 self-locks to the inside of the first mating part 43 under the restoring action of the reset part 3.

[0073] When the user pushes the pull-out box 5 along the bottom shell 1 near the closed end 12 while the latch 6 is in the self-locking state, it causes the latch 6 to lift the second mating part 44 and compress the reset part 3 at the same time, so that the latch 6 disengages from the flip 4 and unlocks under the restoring action of the reset part 3.

[0074] Therefore, the pull-out electrical control box structure provided by the present invention adopts a horizontally arranged bottom shell 1 and a horizontally pull-out box 5 movably installed inside the bottom shell 1. The user can push and pull the pull-out box 5 to drive the locking buckle 6 at its end to act with the flip buckle 4 and the reset member 3 inside the bottom shell 1, thereby driving the pull-out box 5 to quickly self-lock or unlock inside the flip buckle 4 through the locking buckle 6.

[0075] Therefore, the pull-out electrical control box structure provided by this invention not only enables the quick disassembly and assembly of the pull-out box 5 and its contained electrical components (such as frequency converters) from the bottom shell 1, facilitating the production, assembly, and after-sales maintenance of the electrical control box, but also allows the bottom shell 1 and pull-out box 5 of the pull-out electrical control box structure to be placed horizontally (overall horizontally) at the top of the middle or lower space within the casing 71 of the air conditioning unit 7. This allows the bottom shell 1 and pull-out box 5 to adopt a single-layer structure in the height direction instead of the traditional double-layer layout of the vertical electrical control box, thereby making full use of the large amount of space within the casing 71 of traditional air conditioners (especially modular units). The wasted horizontal space is used to install the electrical control box structure, and a large amount of height space in the lower space inside the modular unit's casing 71 can be freed up for installing the vertical electrical control box. Since the oil separator and gas separator of the air conditioner usually adopt a structural layout with small dimensions in the vertical direction, the oil separator and gas separator can be compactly concentrated and stacked in the lower space inside the casing 71. This avoids the horizontal bottom shell 1 and pull-out box 5 located in the middle space or the top of the lower space inside the casing 71 from blocking the oil separator, gas separator and other components in the lower space. This facilitates the production, assembly and after-sales maintenance of the modular unit, improves the unit's space utilization and reduces the unit's maintenance costs.

[0076] Please refer to the following: Figure 1-5 In one embodiment of the pull-out electrical control box structure provided by the present invention, the flip-top 4 includes:

[0077] 41-inch panel;

[0078] The hinge part 42 is provided at one axial end of the buckle plate 41 and is hinged to the hinge seat 2.

[0079] The first mating part 43 is provided at the other end of the buckle plate 41 opposite to the hinge part 42 in the axial direction;

[0080] The second mating part 44 and the first mating part 43 are located in the middle of the buckle plate 41 near the first mating part 43;

[0081] The pull-out box 5 has a fixed seat 51 at one axial end, and the latch 6 is connected to the fixed seat 51.

[0082] Therefore, this embodiment defines the preferred structural layout of the flip-top 4 and the preferred connection form between the pull-out box 5 and the latch 6.

[0083] Please refer to the following: Figure 1-5 In one embodiment of the pull-out electrical control box structure provided by the present invention, the first mating part 43 is a fastening part that bends from the other end of the axial direction of the buckle plate 41 toward the bottom wall of the bottom shell 1. The two ends of the fastening part extend out of the axial sides of the buckle plate 41 respectively. A pair of second mating parts 44 are provided. The pair of second mating parts 44 are respectively connected to the ends of the corresponding parts of the fastening parts that extend out of the buckle plate 41 toward the connecting part. The second mating part 44 is an inclined plate that extends obliquely from the end of the fastening part in a direction away from the fastening part.

[0084] Therefore, this embodiment defines the preferred structural layout and connection form of the first mating part 43 and the second mating part 44.

[0085] Please refer to the following: Figure 1 , 6 10. In one embodiment of the pull-out electrical control box structure provided by the present invention, the latch 6 includes a straight section 61 connected to the fixed base 51 and a bent section connected to both ends of the straight section 61 and arranged facing each other. The bent section includes a connecting part 621 connected to the straight section 61 and a third mating part 622 connected to the end of the connecting part 621 away from the straight section 61 and matching the fastening part and the inclined plate. The straight section 61, the connecting part 621 and the third mating part 622 constitute a C-shaped latch 6.

[0086] Please refer to the following: Figure 10-14 When the user pushes the pull-out box 5 along the bottom shell 1 near the closed end 12 and compresses the reset member 3, the third mating part 622 first pushes the fastening part upward (driving the buckle plate 41 to flip upward around the hinge seat 2 away from the bottom wall of the bottom shell 1 through the hinge part 42 and push the fastening part upward). Then, as the user continues to push the pull-out box 5 near the closed end 12, the third mating part 622 moves along the surface of the fastening part near the hinge part 42 and continues to push the fastening part until the third mating part 622 completely passes over and disengages from the fastening part. At this time, the user releases the pull-out box 5 so that the fastening part flips down and returns to its original position near the bottom wall of the bottom shell 1 under its own weight. The latch 6 moves close to the fastening part under the action of the reset member 3 pushing the pull-out box 5 away from the closed end 12 (near the open end 11) by its restoring action until the latch 6 abuts and self-locks to the inside of the fastening part.

[0087] Please refer to the following: Figure 15-17When the user pushes the pull-out box 5 in the self-locking state of the latch 6 to move along the bottom shell 1 near the closed end 12 and compress the reset member 3, the third mating part 622 first pushes the inclined plate upward (driving the latch plate 41 to flip upward around the hinge seat 2 away from the bottom wall of the bottom shell 1 through the hinge part 42 to push the inclined plate). Then, as the user continues to push the pull-out box 5 near the closed end 12, the third mating part 622 moves along the inclined surface of the inclined plate near the hinge part 42 and continues to push the inclined plate until the third mating part 622 reaches the bottom end of the inclined plate (away from the end of the fastening part) and the height of the fastening part raised by the latch plate 41 exceeds a certain height range of the highest point of the latch 6, or the mating part completely exceeds and disengages from the inclined plate.

[0088] Please refer to the following: Figure 18-19 At this time, the user releases the pull-out box 5, and the latch 6 rebounds quickly under the action of the reset member 3 pushing the pull-out box 5 away from the closed end 12 (close to the open end 11) until the latch 6 directly disengages from the flip latch 4 (when the third mating part 622 reaches the bottom of the inclined plate) or pushes the inclined plate upwards to release it due to its own weight (when the mating part completely passes the inclined plate) and disengages from the flip latch 4. The pull-out box 5 then switches to the unlocked state where it can be freely pulled out.

[0089] Please refer to the following: Figure 1-10 In one embodiment of the pull-out electrical control box structure provided by the present invention, the hinge seat 2 includes:

[0090] Support plate 21 is installed on the inner wall of the closed end 12;

[0091] A pair of bearings 22 are spaced apart on the side of the support plate 21 facing away from the open end 11;

[0092] The hinge shaft 23 is fixedly mounted on a pair of bearings 22.

[0093] The hinge part 42 is a bushing that is hinged to the hinge shaft 23.

[0094] Therefore, this embodiment provides a preferred structural layout and preferred connection method for the hinge seat 2 and the hinge part 42.

[0095] Please refer to the following: Figure 1-3 In one embodiment of the pull-out electrical control box structure provided by the present invention, the end of the bushing away from the first mating part 43 is provided with a limiting right angle 421. The limiting right angle 421, by cooperating with the inner wall of the closed end 12, limits the flipping stroke range of the flip buckle 4 around the hinge seat 2 to between a straight posture parallel to the bottom wall of the bottom shell 1 and an upward flipping posture tilted and flipped near the top opening of the bottom shell 1.

[0096] Therefore, in this embodiment, the flip 4 is limited to rotating counterclockwise around the hinge seat 2 to ensure the self-locking and unlocking of the pull-out box 5.

[0097] Please refer to the following: Figure 1-3 6. In one embodiment of the pull-out electrical control box structure provided by the present invention, the fixing seat 51 is a pipe clamp installed on one axial end of the pull-out box 5, and the straight section 61 is tubular and fixedly installed on the pipe clamp.

[0098] Therefore, this embodiment provides a preferred structural layout for the fixed base 51 and a preferred connection method between it and the straight section 61.

[0099] Please refer to the following: Figure 2 , 6 9. In one embodiment of the pull-out electrical control box structure provided by the present invention, the inner wall of the bottom shell 1 on at least one side in the axial direction is provided with a guide structure 13, and the outer wall of the pull-out box 5 on at least one side in the axial direction is provided with a sliding structure 52 that cooperates with the guide structure 13.

[0100] Therefore, in this embodiment, the stability is improved by the cooperation of the guide structure 13 and the sliding structure 52 between the bottom shell 1 and the pull-out box 5.

[0101] Please refer to the following: Figure 2 , 6 9. In a preferred embodiment of the pull-out electrical control box structure provided by the present invention, the guide structure 13 is a guide groove, and the sliding structure 52 is a sliding rib that matches the guide groove.

[0102] Therefore, this embodiment provides an economical and reliable structural layout and connection method for the guide structure 13 and the sliding structure 52.

[0103] Please refer to the following: Figure 2 , 6 9. In a more preferred embodiment of the pull-out electrical control box structure provided by the present invention, the sliding rib extends through the entire pull-out box 5 along the axial direction (length direction), and the guide groove length L = sliding rib L1 + latch 6 width B, where latch 6 width B is the distance between the third mating part 622 and the corresponding outer side of the straight section 61.

[0104] Therefore, this embodiment can ensure that the sliding stroke of the pull-out box 5 is redundant, so that the pull-out box 5 can be completely closed within the bottom shell 1.

[0105] Please refer to the following: Figure 1-2 In one embodiment of the pull-out electrical control box structure provided by the present invention, the reset member 3 is a reset spring connected between the inner wall of the closed end 12 facing the open end 11 and the axial end of the pull-out box 5 facing the closed end 12.

[0106] Therefore, this embodiment provides a structural form for the reset component 3 that offers reliable and economical reset action.

[0107] Please see Figure 20 The present invention also provides an air conditioner, including an air conditioning unit 7 and the above-mentioned pull-out electrical control box structure. The bottom shell 1 is installed on a fixed object inside the housing 71 of the air conditioning unit 7, and the open end 11 faces the outside of the housing 71. The pull-out box 5 can extend or be pulled out from the open end 11 along the bottom shell 1 away from the closed end 12 when the latch 6 is unlocked.

[0108] Please see Figure 20 In one embodiment of the air conditioner provided by the present invention, the interior of the housing 71 is divided into an upper space 73 and a lower space 74 by a shelf 72 located in the middle of the housing 71. A pull-out electrical control box structure is located on the back of the shelf 72, at the bottom of the upper space 73, and placed in the lower space 74.

[0109] Please see Figure 20 In a preferred embodiment of the air conditioner provided by the present invention, the shelf 72 is provided with a hollow structure 721, and a water receiving tray 75 is embedded in the hollow structure 721. The top edge of the bottom shell 1 is installed on the bottom periphery of the hollow structure 721. The water receiving tray 75 serves as the top cover of the pull-out electrical control box structure, covering the top opening of the bottom shell 1, and together with the bottom shell 1 and the casing 71, forms a closed space that encloses the pull-out box 5.

[0110] Therefore, when the pull-out electrical control box structure provided by the present invention is applied to air conditioners (especially modular units), there is no need to set an additional cover for the electrical control box. Instead, the water receiving tray 75 inside the casing 71 of the air conditioning unit 7 can be used directly as the cover of the electrical control box, avoiding the cumbersome screw sealing and opening of the electrical control box. The opening and closing is simple and easy to observe.

[0111] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art should understand that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
