Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to an outdoor unit for an air conditioner. Background Technology

[0002] An air conditioner's outdoor unit typically includes components such as a compressor, condenser, throttling element, and evaporator. The electrical box, which controls the operation of the electrical components, is usually installed on the middle partition, and its installation position is usually close to the compressor cavity.

[0003] In related technologies, the electrical boxes of outdoor air conditioning units are mostly fixed installations, mounted vertically or horizontally on the middle partition. For vertically mounted electrical boxes, the internal circuit boards are exposed from the side, making it easy for insects to enter the PCB surface, causing short circuits and damaging the electrical box. Furthermore, the ventilation systems on both sides of vertically mounted electrical boxes can trap corrosive gases and dust on the circuit board surface, increasing the risk of electrical box failure. While horizontally inverted electrical boxes can prevent insects from entering to some extent, the box needs to be connected between the middle partition and the right side panel, requiring high manufacturing precision, and often resulting in improper installation. Moreover, the controller connector of the inverted electrical box faces downwards, requiring installers to bend over to operate, increasing the difficulty of maintenance. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide an outdoor air conditioning unit that is deformable, has good sealing properties, and is easy to maintain.

[0005] To achieve the above objectives, an outdoor air conditioning unit according to an embodiment of the present invention includes: a housing; a partition plate, the partition plate being vertically disposed within the housing and separating a compressor cavity and an air duct cavity; an outdoor fan, the outdoor fan being installed within the air duct cavity; a compressor, the compressor being installed within the compressor cavity; and an electrical box assembly, the electrical box assembly being installed on the partition plate; the electrical box assembly includes: a transition bracket, the transition bracket being installed on the partition plate; and an electrical box body, the electrical box body being installed on the transition bracket, and the electrical box body being... The transition bracket is rotatable; wherein, the front and rear sides of the transition bracket are respectively constructed with vertically extending vertical rods, and the top of the vertical rods on both sides of the transition bracket are respectively constructed with horizontally extending horizontal parts. The electrical box body can be selectively connected with the vertical rods or the horizontal parts on both sides to switch between a vertical state and an inverted state. When the electrical box body is rotated to the vertical state, it is vertically fixed between the vertical rods on both sides. When the electrical box body is rotated to the inverted state, it is fixed between the horizontal parts on both sides.

[0006] The outdoor unit of the air conditioner according to an embodiment of the present invention has deformability, good sealing performance, and is easy to maintain.

[0007] According to some specific embodiments of the present invention, each of the two vertical rod portions has a vertical guide groove extending in the vertical direction on its opposite side, and each of the two horizontal portions has a horizontal guide groove on its opposite side. The vertical guide grooves on both sides are respectively connected to the horizontal guide grooves. The electrical box body has guide pins extending into the vertical guide grooves or the horizontal guide grooves on its opposite sides. The guide pins are slidably engaged with the vertical guide grooves and the horizontal guide grooves. When the electrical box body is in the vertical state, the guide pins are located in the vertical guide grooves, and when the electrical box body is flipped to the inverted state, the guide pins slide into the horizontal guide grooves.

[0008] The above technical solution has the following advantages or beneficial effects: the switching process of flipping the electrical box body is simple to operate, does not require disassembling extra parts, and facilitates the state switching.

[0009] According to some specific embodiments of the present invention, the end of the horizontal guide groove away from the air duct cavity is configured as a stop groove portion adapted to the shape of the guide pin, and the guide pin is rotatable in conjunction with the stop groove portion.

[0010] The above technical solution has the following advantages or beneficial effects: the stop groove can limit the guide pin.

[0011] According to some specific embodiments of the present invention, positioning protrusions are constructed on opposite sides of the electrical box body. When the electrical box body is in the vertical state, the positioning protrusions are lower than the guide pin and are located on the side of the guide pin facing the air duct cavity when the electrical box body is in the inverted state. A locking notch is constructed at one end of the horizontal guide groove facing the air duct cavity, and the positioning protrusions are embedded in the locking notch when the electrical box body is in the inverted state.

[0012] The above technical solution has the following advantages or beneficial effects: it further improves the reliability of the structure and makes the positioning and fixing effect more stable.

[0013] According to some specific embodiments of the present invention, the lower part of the vertical guide groove is provided with a stop block, and a clearance gap is formed between the stop block and the side wall of the vertical guide groove. When the electrical box body is flipped to the vertical state, the positioning protrusion passes downward through the clearance gap and the guide pin stops above the stop block.

[0014] The above technical solution has the following advantages or beneficial effects: the stop block can effectively limit the guide pin that slides down into place, preventing the guide pin from sliding down and allowing the electrical box body to remain stably in a vertical state.

[0015] According to some specific embodiments of the present invention, the top wall of the horizontal guide groove is provided with a first clearance opening and a second clearance opening, the first clearance opening being corresponding to the extension direction of the vertical guide groove, and the second clearance opening being disposed adjacent to the stop groove.

[0016] The above technical solution has the following advantages or beneficial effects: by constructing the first clearance opening and the second clearance opening, the guide pin and the positioning protrusion can be directly passed through the first clearance opening, thus facilitating installation.

[0017] According to some specific embodiments of the present invention, the transition bracket further includes: an upper pressure beam connected between the tops of the vertical rods on both sides; and a lower support platform connected between the lower parts of the vertical rods on both sides; wherein, when the electrical box body is in the inverted state, the upper pressure beam presses against the top of the electrical box body, and the lower support platform supports the bottom of the electrical box body.

[0018] The above technical solution has the following advantages or beneficial effects: it further improves the structural stability of the electrical box assembly in the inverted state. Furthermore, the electrical box body is constructed with a box body, the box body including: a flat mounting part, the flat mounting part being adapted to mount a circuit board; a heat dissipation part, the heat dissipation part being connected to one side of the flat mounting part in the thickness direction, the heat dissipation part being located below the flat mounting part when the electrical box body is in the inverted state; wherein, the lower support platform protrudes towards the air duct cavity, and after the electrical box body is flipped to the inverted state, the lower support platform is supported on the bottom of the heat dissipation part.

[0019] The above technical solution has the following advantages or beneficial effects: the heat generated by the internal components of the electrical box is quickly carried away, improving heat dissipation efficiency and ensuring better heat dissipation performance of the electrical box components.

[0020] Furthermore, the lower support platform includes: a connecting side plate, which is connected to the vertical rod portion on both sides and extends toward the air duct cavity; and an inclined plate, which is connected between the connecting side plates on both sides and is inclined, with the bottom of the inclined plate adjacent to the vertical rod portion and the top of the inclined plate extending inclinedly toward the air duct cavity.

[0021] The above technical solution has the following advantages or beneficial effects: the inclined side plate can avoid the electrical box body during the flipping process, and can also provide better support at the bottom of the electrical box body when it is inverted. According to some specific embodiments of the present invention, the partition plate is provided with vertical guide ribs, and the transition bracket is provided with outer guide grooves on both sides. The outer guide grooves extend in the vertical direction, and the vertical guide ribs cooperate with the outer guide grooves to allow the transition bracket to be detachably installed on the partition plate.

[0025] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In the description of this invention, "first feature" and "second feature" may include one or more of the features.

[0027] In the description of this invention, "a plurality of" means two or more.

[0028] The outdoor unit 1 of an air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0029] like Figures 1-10 As shown, the outdoor unit 1 of the air conditioner according to an embodiment of the present invention includes: a housing 100, a partition 200, an outdoor fan 300, a compressor 400, and an electrical box assembly 500.

[0030] The partition 200 is vertically installed inside the housing 100 and separates the compressor 400 cavity and the air duct cavity. The outdoor fan 300 is installed in the air duct cavity, the compressor 400 is installed in the compressor 400 cavity, and the electrical box assembly 500 is installed in the partition 200.

[0031] The electrical box assembly 500 includes a transition bracket 510 and an electrical box body 520, wherein the transition bracket 510 is mounted on the partition plate 200. The electrical box body 520 is mounted on the transition bracket 510 and is rotatable relative to the transition bracket 510.

[0032] The transition bracket 510 has vertically extending vertical rods 511 on its front and rear sides, and horizontally extending horizontal parts 512 on the top of the vertical rods 511 on both sides. The electrical box body 520 can be selectively connected to either the vertical rods 511 or the horizontal parts 512 on both sides to switch between a vertical and an inverted state. When the electrical box body 520 is flipped to the vertical state, it is fixed by the vertical rods 511 on both sides. When the electrical box body 520 is flipped to the inverted state, it is fixed by the horizontal parts 512 on both sides.

[0033] For example, the transition bracket 510 is parallel to the mounting surface of the partition 200. When the electrical box body 520 is in a vertical position, it remains vertical along with the side of the partition 200 and the transition bracket 510. When the electrical box assembly 500 is initially installed, the electrical box body 520 is in an inverted position. When maintenance is required, the electrical box body 520 can be flipped to a vertical position. The electrical box assembly 500 contains components such as a circuit board 51 and a radiator 52, which control the air conditioner. The vertical rods 511 on both sides of the transition bracket 510 are symmetrically arranged, and the horizontal parts 512 on both sides of the transition bracket 510 are symmetrically arranged. The electrical box body 520 remains fixed when flipped to a vertical position and in an inverted position.

[0034] According to an embodiment of the present invention, the outdoor unit 1 of the air conditioner can achieve corresponding functional optimization in different usage scenarios by flexibly switching between vertical and inverted states of the electrical box body 520. During normal installation and use, the electrical box body 520 remains in an inverted state, which can completely enclose the internal circuit board 51 within the box body 53, effectively preventing various crawling insects from entering, and significantly reducing the accumulation of dust and corrosive gases floating in the air duct cavity on the surface of the circuit board 51, thereby reducing the possibility of electrical box malfunction due to pollution or corrosion, and improving its overall sealing and protection performance.

[0035] When inspection and maintenance are required, the electrical box body 520 can be simply flipped back to a vertical position, providing a more convenient inspection view for installers or operators without the need to bend over or adopt an inconvenient posture, greatly reducing the difficulty of maintenance work. Furthermore, the electrical box body 520 is fixedly installed on the middle partition 200 via a transition bracket 510, eliminating the need for additional connection to the right side panel. This design reduces the stringent requirements for dimensional accuracy during the overall manufacturing process and avoids problems with the electrical box assembly 500 not being properly assembled due to poor installation fit, further enhancing the reliability of the structure and the ease of installation.

[0036] Therefore, the outdoor unit 1 of the air conditioner according to the embodiment of the present invention has deformability, good sealing performance, and is easy to maintain.

[0037] In some specific embodiments of the present invention, such as Figure 5 and Figure 6 As shown, each of the vertical rod portions 511 on both sides has a vertical guide groove 513 extending in the vertical direction on the opposite side, and each of the horizontal portions 512 on both sides has a horizontal guide groove 514 on the opposite side, and the vertical guide grooves 513 on both sides are connected to the horizontal guide grooves 514 respectively.

[0038] The electrical box body 520 has guide pins 521 on its opposite sides that extend into the vertical guide groove 513 or the horizontal guide groove 514. The guide pins 521 are slidably engaged with the vertical guide groove 513 and the horizontal guide groove 514. When the electrical box body 520 is in a vertical state, the guide pins 521 are located in the vertical guide groove 513. When the electrical box body 520 is flipped to an inverted state, the guide pins 521 slide into the horizontal guide groove 514.

[0039] For example, the guide pins 521 are symmetrically arranged on both sides along the width direction of the electrical box body 520. By cooperating with the vertical guide groove 513 or the horizontal guide groove 514, the guide pins 521 on both sides can stably guide and fix the flipping and switching process of the electrical box body 520, making the state switching process smoother and more stable. At the same time, the electrical box body 520 can be reliably limited in both states.

[0040] When it is necessary to switch the electrical box body 520 from a vertical state to an inverted state, the electrical box body 520 can be lifted first so that the guide pin 521 slides upward along the vertical guide groove 513. When it slides to the position of the horizontal guide groove 514, it can continue to slide along the horizontal guide groove 514. During the guiding sliding process, the electrical box body 520 connected to the guide pin 521 performs a flipping action, so that it flips from a vertical state to a horizontal inverted state. The switching process of flipping the electrical box body 520 is simple to operate, does not require disassembling extra parts, and is convenient to complete the state switching. The structural design is simple and ingenious.

[0041] Similarly, when it is necessary to switch the electrical box body 520 from an inverted state to a vertical state, push the guide pin 521 to slide along the horizontal guide groove 514 toward the vertical guide groove 513. After sliding to the entrance position of the vertical guide groove 513, drive the electrical box body 520 to flip downward, so that the guide pin 521 slides into the vertical guide groove 513 and moves downward along the groove to the position, thus fixing the electrical box body 520 in a vertical state. The operation is equally simple and smooth.

[0042] Furthermore, such as Figure 5 and Figure 6 As shown, the end of the horizontal guide groove 514 away from the air duct cavity is configured as a stop groove 515 that matches the shape of the guide pin 521, and the guide pin 521 can rotate in conjunction with the stop groove 515.

[0043] When the electrical box body 520 is flipped to an inverted state, it can move a certain distance along the horizontal guide groove 514, allowing the transition bracket 510 to avoid the electrical box body 520 from flipping. When the guide pin 521 moves into the stop groove 515, the stop groove 515 can limit the guide pin 521 and generate a certain angle of rotation, assisting the flipping of the electrical box body 520. In addition, the stop groove 515 can also prevent the guide pin 521 from dislodging from the horizontal guide groove 514 when moving horizontally, improving the structural stability of the electrical box body 520 in the inverted state.

[0044] In some specific embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the electrical box body 520 has positioning protrusions 522 on opposite sides. When the electrical box body 520 is in a vertical state, the positioning protrusions 522 are lower than the guide pin 521, and when the electrical box body 520 is in an inverted state, they are located on the side of the guide pin 521 facing the air duct cavity. The end of the horizontal guide groove 514 facing the air duct cavity has a locking notch 516, and the positioning protrusions 522 are embedded in the locking notch 516 when the electrical box body 520 is in an inverted state.

[0045] For example, the positioning protrusions 522 protrude symmetrically on both sides of the electrical box body 520. When the electrical box body 520 is in an inverted state, the positioning protrusions 522 fit precisely into the corresponding engagement notches 516, while the guide pins 521 are also within the horizontal guide grooves 514. Thus, the positioning protrusions 522 and guide pins 521, at different positions in the horizontal direction, can provide bidirectional positioning for the electrical box body 520, preventing the electrical box body 520 from shifting during inverted operation, further improving the reliability of the structure, and making the positioning and fixing effect more stable.

[0046] Furthermore, such as Figure 8 As shown, the lower part of the vertical guide groove 513 has a stop 519, and a clearance gap is formed between the stop 519 and the side wall of the vertical guide groove 513. When the electrical box body 520 is flipped to the vertical state, the positioning protrusion 522 passes downward through the clearance gap and the guide pin 521 stops above the stop 519.

[0047] For example, the stop 519 is located on one side of the adjacent air duct cavity within the vertical guide groove 513, while the clearance is formed on the side of the vertical guide groove 513 away from the air duct cavity. The stop 519 can effectively limit the guide pin 521 as it slides downwards, preventing it from sliding down and allowing the electrical box body 520 to remain stably in a vertical position. At the same time, the clearance provides sufficient space for the positioning protrusion 522 to move, preventing the positioning protrusion 522 from interfering with the guide pin 521 as it slides down into position. This ensures that the electrical box body 520 can be smoothly switched and fixed in a vertical position. The structure is compact and reasonable, and the flipping process is smooth.

[0048] In some specific embodiments of the present invention, such as Figure 8 As shown, the top wall of the horizontal guide groove 514 is constructed with a first clearance opening 501 and a first clearance opening 501. The first clearance opening 501 corresponds to the extension direction of the vertical guide groove 513 and is disposed adjacent to the stop groove portion 515.

[0049] When the electrical box body 520 needs to be installed on the transition bracket 510 and kept in a vertical position, by constructing the first clearance opening 501, the guide pin 521 and the positioning protrusion 522 can be directly passed through the first clearance opening 501, so that the electrical box body 520 can be vertically installed into the transition bracket 510.

[0050] When it is necessary to install the point switching body on the transition bracket 510 and keep it in the inverted position, such as Figure 10 As shown, the positioning protrusion 522 can first pass downward through the first clearance opening 501 into the connection between the vertical guide groove 513 and the horizontal guide groove 514. Then, the electrical box body 520 is rotated so that the guide pin 521 passes through the first clearance opening 501 into the horizontal guide groove 514. At this time, both the positioning protrusion 522 and the guide pin 521 are in the horizontal guide groove 514. Then, the electrical box body 520 is moved horizontally along the horizontal guide groove 514 so that the positioning protrusion 522 engages with the engagement notch 516 and can be installed in place.

[0051] Understandably, the first clearance opening 501 and the second clearance opening 501 provide clearance convenience for the installation of the electrical box body 520 and the transition bracket 510. However, the electrical box body 520 can also be installed without relying on the second clearance notch. When the electrical box body 520 is in a vertical state, the guide pin 521 can switch between the vertical guide groove 513 and the horizontal guide groove 514, and can also complete the flipping switch between the vertical state and the inverted state of the electrical box body 520.

[0052] In some specific embodiments of the present invention, such as Figure 9 As shown, the transition bracket 510 further includes an upper pressure beam 517 and a lower support platform 518. The upper pressure beam 517 connects the tops of the vertical rods 511 on both sides, and the lower support platform 518 connects the lower parts of the vertical rods 511 on both sides. When the electrical box body 520 is in an inverted state, the upper pressure beam 517 presses against the top of the electrical box body 520, and the lower support platform 518 supports the bottom of the electrical box body 520.

[0053] When the electrical box body 520 is in an inverted state and operating normally, the upper pressure beam 517 and the lower support platform 518 can respectively limit and fix the electrical box body 520 from the top and bottom, preventing the electrical box body 520 from shaking or shifting during the operation of the outdoor unit 1 of the air conditioner. This further improves the structural stability of the electrical box assembly 500 in the inverted state and also ensures that the relative position of the heat dissipation part 540 and the air duct cavity remains stable, ensuring that the heat dissipation effect is not affected. At the same time, the inverted electrical box body 520 can also prevent crawling insects from entering the electrical box body 520, further improving the protection of the electronic components inside the electrical box body 520.

[0054] Furthermore, such as Figure 8 As shown, the electrical box body 520 is constructed with a box body 53, which includes a flat mounting part 530 and a heat dissipation part 540. The flat mounting part 530 is suitable for mounting the circuit board 51, and the heat dissipation part 540 is connected to one side of the flat mounting part 530 in the thickness direction. When the electrical box body 520 is in an inverted state, the heat dissipation part 540 is located below the flat mounting part 530.

[0055] The lower support platform 518 protrudes towards the air duct cavity. After the electrical box body 520 is flipped to an inverted state, the lower support platform 518 is supported on the bottom of the heat dissipation part 540.

[0056] It is understood that the flat mounting portion 530 and the heat dissipation portion 540 are an integral structure. The heat dissipation portion 540 protrudes from the flat mounting portion 530. When the electrical box body 520 is in an inverted state, the heat dissipation portion 540 protrudes downward to contact the flowing air for heat dissipation. At the same time, the flat mounting portion 530 conforms to the contour of the top of the housing 100, which can reduce the overall space occupied by the electrical box body 520 and avoid interference with the arrangement of other components inside the housing 100.

[0057] When the electrical box body 520 is in a vertical position, the heat dissipation part 540 protrudes towards the air duct cavity. The protruding heat dissipation part 540 can extend into the air duct cavity through the outer guide groove 211 on the partition plate 200 and directly contact the flowing air in the air duct cavity. This can quickly carry away the heat generated by the internal components of the electrical box body 520, improve heat dissipation efficiency, ensure better heat dissipation performance of the electrical box assembly 500, avoid performance degradation of the electrical box due to heat accumulation, and improve the stability of the electronic components.

[0058] In some specific embodiments of the present invention, such as Figure 9As shown, the lower support platform 518 includes a connecting side plate 54 and an inclined plate 55. The connecting side plates 54 are respectively connected to the vertical rod portions 511 on both sides and extend towards the air duct cavity. The inclined plate 55 is connected between the connecting side plates 54 on both sides and is inclined, with the bottom of the inclined plate 55 adjacent to the vertical rod portion 511 and the top of the inclined plate 55 extending inclinedly towards the air duct cavity.

[0059] For example, the connecting side plate 54 is constructed in a triangular or trapezoidal shape, wider at the top and narrower at the bottom. The inclined plate 55 is connected to the long side of the connecting side plate 54 and adapts to the contour of the heat sink 52. The width between the two connecting side plates 54 is wider than the width of the electrical box body 520. By constructing the connecting side plate 54 and the inclined plate 55, when the electrical box body 520 flips between a vertical and inverted state, the inclined plate 55 can avoid obstructing the electrical box body 520 during the flipping process. Furthermore, the inclined side plate can also provide better support at the bottom of the electrical box body 520 when it is inverted, without unnecessarily obstructing the heat sink 540 extending into the air duct cavity, ensuring that air can flow smoothly over the surface of the heat sink 540 without affecting the heat dissipation effect.

[0060] In some specific embodiments of the present invention, such as Figure 4 As shown, the partition plate 200 is constructed with vertical guide ribs 210, and the transition bracket 510 is constructed with outer guide grooves 211 on both sides. The outer guide grooves 211 extend in the vertical direction. The vertical guide ribs 210 and the outer guide grooves 211 cooperate to allow the transition bracket 510 to be detachably installed on the partition plate 200.

[0061] For example, the vertical guide rib 210 is constructed as a strip extending vertically, and the top of the outer guide groove 211 is closed, thus maintaining a stop and fixation with the outer guide groove 211 when the vertical guide rib 210 is installed in place. The tight fit between the vertical guide rib 210 and the outer guide groove 211 provides effective guidance for the installation process of the transition bracket 510, thereby significantly improving the speed and accuracy of installation positioning. This design not only realizes the detachable connection between the transition bracket 510 and the middle partition 200, but also brings great convenience to production assembly and subsequent maintenance disassembly. The entire installation structure design is simple and clear, with accurate and reliable positioning, effectively reducing the operational difficulty in the assembly process and greatly improving the efficiency and smoothness of the overall assembly.

[0062] Furthermore, when the electrical box assembly 500 needs maintenance, the electrical box body 520, along with the transition bracket 510, can be removed from the outer guide groove 211 of the partition plate 200. Alternatively, when installing the electrical box assembly 500, the electrical box body 520 and the transition bracket 510 can be pre-assembled, and then the electrical box body 520, along with the transition bracket 510, can be installed in the outer guide groove 211 of the partition plate 200. After the vertical guide rib 210 is installed in conjunction with the outer guide groove 211, the transition bracket 510 can be firmly fixed in the preset position of the partition plate 200 without the need for additional fixing connectors, simplifying the overall assembly process.
