[0041] See also Figures 1 to 3As shown, the ceiling-mounted air conditioner indoor unit of this embodiment includes a housing 1, a fan 6 and an electrical box 2. The housing 1 has a bottom surface 14 with an air outlet 12; the fan 6 is arranged in the housing 1; the electrical box 2 is mounted on the housing 1 and is configured to be movable relative to the housing 1 to switch between a first position at least partially located above the bottom surface 14 and a second position at least partially located below the bottom surface 14. Figure 1 and Figure 2 The diagram shows a three-dimensional structure of the ceiling-mounted air conditioner indoor unit when the electrical box 2 is located at the first position (normal working position). Figure 3 The schematic diagram shows the structure of the ceiling-mounted air conditioner indoor unit with the electrical box 2 located at the second position (maintenance position for easy maintenance).

[0042] When it is necessary to repair and debug the electrical box 2 of the indoor unit of the ceiling-mounted air conditioner, the electrical box 2 can be moved to a lower second position for repair and debugging. After the repair and debugging is completed, the electrical box 2 is moved to the first position, wherein the electrical box 2 is higher than the bottom surface of the housing 1 when it is in the first position, and at least partially lower than the bottom surface of the housing 1 when it is in the second position. Generally, the bottom surface 14 of the indoor unit of the ceiling-mounted air conditioner is roughly flush with the ceiling. When working normally, the electrical box 2 is hidden above the ceiling, does not occupy the indoor space, and makes the indoor space more tidy and simple. When it is necessary to repair and debug the electrical box 2, the electrical box 2 can be moved to a second position at least partially located below the ceiling for the convenience of the staff to work, which improves the problem of the electrical box of the indoor unit of the ceiling-mounted air conditioner in the prior art that it is not convenient to repair and debug. The difficulty of the staff to repair and debug the electrical components in the electrical box 2 is reduced, which is conducive to reducing the labor intensity of the staff and improving the labor efficiency.

[0043] See also Figure 1 The ceiling-mounted air-conditioning indoor unit of this embodiment further comprises a mounting structure 11 disposed on the top of the housing 1 , and the mounting structure 11 is used to connect to the roof so as to mount the air-conditioning indoor unit in the ceiling.

[0044] In some embodiments, the electrical box 2 at the second position is lower than the bottom surface 14. The electrical box 2 at the second position is located below the bottom surface 14 as a whole, that is, the electrical box 2 is located below the ceiling as a whole. After the electrical box 2 is opened, the staff can conveniently repair and debug all electrical components of the electrical box 2, which is conducive to reducing the working dead angle.

[0045] In some embodiments, the electrical box 2 includes an electrical box body 21 having an opening and an electrical box cover 22 covering the opening. Figure 1 and 2 When the electrical box 2 is located at the first position, the electrical box cover 22 is located at one end of the electrical box body 21 along the horizontal direction. Figure 3When the electrical box 2 is in the second position, the electrical box cover 22 is located at the bottom of the electrical box body 21. The electrical box body 21 in the second position is open downward, and after opening the electrical box cover 22, the staff can conveniently repair and debug the electrical components in the electrical box body 21, which reduces the difficulty of the staff to repair and debug the electrical components in the electrical box 2, and is conducive to reducing the labor intensity of the staff and improving the labor efficiency.

[0046] In some other optional embodiments, when the electrical box 2 is in the first position, the electrical box cover 22 is located at one end of the electrical box body 21 along the horizontal direction, and when the electrical box 2 is in the second position, the electrical box cover 22 is located at the same end of the electrical box body 21 along the horizontal direction as when the electrical box 2 is in the first position, and the opening of the electrical box body 21 is oriented in the horizontal direction, so that the staff can directly face the inner cavity installed in the electrical box body 21, which is convenient for observing and repairing and debugging the electrical components in the electrical box 2, and the staff can conveniently repair and debug the electrical components in the electrical box body 21, which reduces the difficulty of the staff to repair and debug the electrical components in the electrical box 2, and is conducive to reducing the labor intensity of the staff and improving the labor efficiency. Further, the switching between the first position and the second position of the electrical box 2 only requires moving the electrical box in the vertical direction, which has the characteristics of simple structure, easy implementation and low cost.

[0047] In some embodiments, when the electrical box 2 is in the first position, the electrical box 2 is attached to the outer surface of the side wall of the housing 1, and the electrical box cover 22 is arranged at the end of the electrical box body 21 away from the housing 1; arranging the electrical box 2 outside the housing 1 is conducive to solving the space inside the housing 1, and is convenient for disassembly and maintenance of the electrical box 2. When the electrical box 2 is in the second position, the electrical box 2 is attached to the bottom surface 14 of the housing 1, and the electrical box cover 22 is located at the bottom end of the electrical box body 21. The opening of the electrical box body 21 in the second position faces downward. After opening the electrical box cover 22, the staff can easily repair and debug the electrical components in the electrical box body 21, which reduces the difficulty of the staff to repair and debug the electrical components in the electrical box 2, and is conducive to reducing the labor intensity of the staff and improving the labor efficiency.

[0048] In some embodiments, the ceiling-mounted air conditioner indoor unit further includes a guide rail 4 and a slider 7. The guide rail 4 is connected to the housing 1 and extends in the vertical direction to guide the electrical box 2 to move from the first position to the second position; the slider 7 is slidably matched with the guide rail 4 and connected to the electrical box 2. The guide rail 4 and the slider 7 guide the electrical box 2 to move in the vertical direction, which can effectively ensure that the electrical box 2 moves along the field, improve the convenience of switching the position of the electrical box 2, and help reduce the labor intensity of maintenance personnel and improve work efficiency.

[0049] The electrical box 2 is connected to the slider 7 via a hinge shaft 9 parallel to the width direction of the guide rail 4, so that the electrical box 2 can rotate toward the bottom surface 14 of the housing 1 after the slider 7 moves to the bottom end of the guide rail 4. Fig. 9 and Fig.10 When the staff needs to maintain the electrical box 2, they first move the electrical box 2 downward along the guide rail. After the electrical box 2 moves downward to the bottom end of the guide rail 4, they rotate the electrical box 2 around the hinge shaft 9 toward the bottom surface of the shell 1, so that the electrical box 2 is rotated to be attached to the bottom surface of the shell 1. At this time, the electrical box cover 22 is located at the bottom end of the electrical box body 21, and the opening of the electrical box body 21 in the second position faces downward. After opening the electrical box cover 22, the staff can easily repair and debug the electrical components in the electrical box body 21, which reduces the difficulty of the staff to repair and debug the electrical components in the electrical box 2, which is conducive to reducing the labor intensity of the staff and improving labor efficiency.

[0050] See also Figures 3 to 7 As shown, the guide rail 4 is vertically mounted on the outer surface of the side wall of the housing 1, the slider 7 is movably mounted on the guide rail 4, and the plate-like component 8 is connected to the slider 7 via a hinge shaft 9, wherein the hinge shaft 9 is parallel to the side wall of the housing 1 on which the guide rail 4 is mounted and is perpendicular to the guide rail 4. The plate-like component 8 is attached to the outer surface of the box wall of the electrical box body 21 opposite to the electrical box cover 22, that is, the electrical box cover 22 is located at the end of the electrical box body 21 away from the housing 1. Therefore, after the electrical box 2 moves in the vertical direction and then rotates to the second position toward the bottom surface of the housing 1, the electrical box cover 22 is located at the lower end of the electrical box body 21.

[0051] See also Figure 5 and 7 The ceiling-mounted air conditioner indoor unit further includes a plate-shaped component 8, which is attached to and connected to the electrical box 2. The plate-shaped component 8 is connected to the slider 7 via a hinge shaft 9. Therefore, the electrical box 2 can move up and down along the guide rail 4 with the slider 7, and can also rotate relative to the slider 7, so that the electrical box 2 can rotate toward the bottom surface of the housing 1 after moving downward to a predetermined position.

[0052] In some embodiments, the ceiling-mounted air conditioner indoor unit further includes a first connection structure 3 and a second connection structure 13. The first connection structure 3 is disposed on the electrical box 2. The second connection structure 13 is disposed on the housing 1 and is configured to be detachably connected to the first connection structure 3 to position the electrical box 2 in the first position.

[0053] See also Figure 1 and Figure 4When the electrical box 2 is in the first position, the first connecting structure 3 and the second connecting structure 13 are connected to limit the movement of the electrical box 2 relative to the shell 1, thereby positioning the electrical box 2 in the first position, which is beneficial to prevent the electrical box 2 from shaking relative to the shell 1, thereby ensuring the reliability of the electrical connection between the electrical components in the electrical box 2 and the electrical components in the shell 1.

[0054] See also Figure 2 The ceiling-mounted air conditioner indoor unit further includes a third connection structure 15 disposed on the housing 1. The third connection structure 15 is configured to be detachably connected to the first connection structure 3. The third connection structure 15 has the same structure as the second connection structure 13. When the electrical box 2 is located at the second position, the third connection structure 15 is connected to the first connection structure 3 to position the electrical box 2 at the second position, fix the electrical box 2 at the second position for maintenance and debugging, and can be shaken relative to the electrical box 2, which is conducive to reducing the difficulty of work for the staff, improving the work efficiency of the staff, and ensuring the work quality.

[0055] Furthermore, the third connecting structure 15 has the same structure as the second connecting structure 13. The first connecting structure 3 can be connected to the second connecting structure 13 to position the electrical box 2 at the first position, and can also be connected to the third connecting structure 15 to position the electrical box 2 at the second position. The same first connecting structure 3 is used to achieve the two positions of the electrical box 2, which simplifies the structure of the air-conditioning indoor unit and reduces the production cost.

[0056] One of the first connection structure 3 and the second connection structure 13 is a buckle, and the other is a buckle structure adapted to the buckle. In this embodiment, the electrical box 2 is positioned at the first position or the second position by a buckle connection, which has the advantages of simple structure, low cost and high reliability.

[0057] In some embodiments, the buckle includes a cantilever portion 31 and a clamping portion 32. One end of the cantilever portion 31 is a fixed end connected to the electrical box 2 or the housing 1, and the other end is a free end. The clamping portion 32 is connected to the free end of the cantilever portion 31 and extends toward the fixed end. The clamping portion 32 is spaced apart from the cantilever portion 31. The clamping portion 32 includes a clamping protrusion 321 facing away from the cantilever portion 31. The clamping portion 32 is configured to be close to the cantilever portion 31 under the action of an external force to disengage from the clamping structure. The clamping portion 32 has elasticity to recover to a predetermined distance from the cantilever portion 31.

[0058] See also Figure 5 and Fig. 9The fixed end of the cantilever part 31 is connected to the electrical box 2, and the free end of the buckle 3 protrudes from the electrical box 2. The snap-fit ​​structure includes a hole that allows the insertion of the end of the buckle away from the fixed end of the cantilever part 31. The hole has a stopper that cooperates with the snap-fit ​​protrusion 321. The stopper is recessed relative to the hole wall to allow the snap-fit ​​protrusion 321 to be embedded. When the buckle is inserted into the hole of the snap-fit ​​structure, the snap-fit ​​protrusion 321 moves closer to the cantilever part 31. After the buckle is inserted into the snap-fit ​​structure, due to the above-mentioned elastic effect, the snap-fit ​​part 32 has the function of restoring to a position spaced a predetermined distance from the cantilever part 31 and cooperating with the stopper of the snap-fit ​​structure. In this embodiment, the snap-fit ​​is used to realize the connection between the electrical box 2 and the housing 1 so as to position the electrical box 2 at the first position or the second position. The snap-fit ​​has the advantages of simple structure, low cost, easy operation and high reliability.

[0059] In some embodiments, the snap-fit ​​structure includes a snap-fit ​​slot provided in the shell 1. After one end of the snap-fit ​​is inserted into the snap-fit ​​slot, the snap-fit ​​protrusion 321 is hooked on the inner surface of the shell 1 under the action of elastic force, thereby realizing the connection between the snap-fit ​​and the snap-fit ​​structure.

[0060] In some embodiments, a mounting hole 36 for connecting to the electrical box 2 is provided at the fixed end of the cantilever portion 31 .

[0061] In some embodiments, the clamping portion 32 further includes an introduction slope 322 and a pressing structure 323. The introduction slope 322 is provided on one side of the clamping protrusion 321 adjacent to the free end of the cantilever portion 31, and the distance between the introduction slope 322 and the cantilever portion 31 gradually decreases in the direction close to the free end of the cantilever portion 31.

[0062] When the buckle is inserted into the hole of the snap-fit ​​structure, the outer edge of the hole abuts against the introduction slope 322 and as the buckle gradually moves toward the inside of the snap-fit ​​structure, the snap-fit ​​portion 32 is pushed toward the cantilever portion 31 so that the buckle is inserted into the snap-fit ​​structure to achieve connection with the snap-fit ​​structure. When the staff positions the electrical box 2 on the housing 1, they only need to push the electrical box 2 to connect the buckle with the snap-fit ​​structure, which has the advantages of simple operation and high work efficiency.

[0063] The pressing structure 323 is disposed at one end of the clamping protrusion 321 away from the introduction inclined surface 322 , so that a worker can press the clamping portion 32 toward the cantilever portion 31 to disengage the clamping protrusion 321 from the clamping structure.

[0064] When it is necessary to release the connection between the buckle and the snap-fit ​​structure, the staff presses the snap-fit ​​part 32 toward the cantilever part 31 through the pressing structure 323 to disengage the snap-fit ​​protrusion 321 from the stopper cooperation with the stopper of the snap-fit ​​structure, thereby allowing the buckle to be pulled out from the hole of the snap-fit ​​structure, which has the advantages of simple operation and high work efficiency.

[0065] In some embodiments, the ceiling-mounted air conditioner indoor unit further includes a cable connector 5, which includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the electrical components in the electrical box 2 through a first cable; the second connecting portion is pluggably connected to the first connecting portion, and is connected to the electrical components in the housing 1 through a second cable.

[0066] The integrated cables use a plug-in connector structure (cable connector 5), which is convenient for quick plugging and unplugging before moving the electrical box 2 to avoid breaking the cables when moving the electrical box 2.

[0067] In some embodiments, the electrical box 2 is provided with a wire hole, and a flexible component 23 is installed on the wire hole. The flexible component 23 is provided with a through hole for allowing the first cable to pass through. The material of the flexible component 23 can be rubber. It is helpful to prevent the first cable from being damaged by friction with a hard component.

[0068] In some embodiments, the ceiling-mounted air conditioner indoor unit is a kitchen indoor unit. Due to the influence of oil smoke and water vapor in the kitchen, the kitchen air conditioner needs frequent maintenance and repair. During maintenance and repair, it is often necessary to open the electrical box of the air conditioner for debugging. However, the indoor unit of the kitchen air conditioner is generally installed above the ceiling, and the electrical box is not easy to open. The ceiling-mounted air conditioner indoor unit of this embodiment is conducive to solving the problem that the kitchen air conditioner needs frequent maintenance and repair and the electrical box is not easy to open.

[0069] The specific process of switching the electrical box 2 from the working position (first position) to the second position (maintenance position) of this embodiment is as follows:

[0070] First, separate the first connecting portion and the second connecting portion of the cable connector 5 to prevent the cable from being damaged during the movement of the electrical box 2. Figure 2 .

[0071] Then, the connection between the first connection structure 3 (clip) and the second connection structure 13 (clip structure) is released, thereby releasing the state in which the electrical box 2 is aligned in the first position. Specifically, both hands press the pressing structures 323 of the clips on both sides of the electrical box 2, so that the clips are deformed and the clip projections 321 are separated from the stopper of the clip structure, and then the electrical box 2 and the clips are rotated (flipped upwards), so that the clips are disengaged from the slots (second connection structure 13) provided on the side walls of the housing 1, thereby releasing the electrical box 2 from being positioned in the first position.

[0072] Then, the electrical box 2 is moved relative to the housing 1. Figure 8 , Fig. 9 , Fig.10As shown: the bottom of the electrical box 2 is connected to the guide rail 4 through a hinge (including a hinge shaft 9 and a plate-shaped component 8), the hinge can move up and down along the guide rail 4, and the limit components are fixed at both ends of the guide rail 4 to limit the movement range of the hinge. Since the electrical box 2 is connected to the hinge, the electrical box 2 moves up and down on the guide rail 4 together with the hinge, and is limited at both ends of the guide rail 4. When the hinge and the electrical box 2 move to the lowest limit block, the hinge and the electrical box 2 will stop moving down, and at the same time, the electrical box 2 and the hinge are turned clockwise 90 degrees. After the electrical box 2 is turned over, the two side buckles can be inserted into the third connecting part 15 (card slot) provided on the bottom surface of the shell. Figure 3 , Fig.10 As shown, the electrical box 2 is fixed intact, and the staff can open the electrical box cover 22 under the air conditioner indoor unit for maintenance and debugging, which will greatly reduce the maintenance difficulty of the staff and can greatly improve the maintenance efficiency.

[0073] The present embodiment provides a novel way of opening the electrical box. With the help of the guide rail 4, the electrical box 2 can be moved and flipped to the bottom of the housing 1 of the air conditioner indoor unit, so that the electrical box 2 can be conveniently opened from the bottom when performing maintenance and debugging of the air conditioner. This will facilitate the staff to perform maintenance and debugging from the bottom, greatly reduce the difficulty of maintenance for the staff, and can greatly improve the maintenance efficiency.

[0074] This embodiment achieves the following technical effects:

[0075] 1. The guide rail 4 and the slider 7 enable the electrical box 2 to be moved to the bottom of the air conditioner indoor unit, making it easier for the staff to perform maintenance and debugging;

[0076] 2. The new hinge mechanism can realize the movement of the electrical box 2 on the guide rail 4, and can also realize the electrical box to be flipped 90 degrees, so that the electrical box 2 can be flipped to a direction that is convenient for maintenance, which is convenient for maintenance and debugging;

[0077] 3. The integrated cables use a pluggable cable connector 5, which is convenient for quick plugging and unplugging before moving the electrical box 2, so as to avoid breaking the cables when moving the electrical box 2;

[0078] 4. The new buckle design allows the staff to easily remove the electrical box when repairing, and it can be fixed again after the repair and debugging is completed;

[0079] 5. The structure of the electric box is simple, which makes maintenance easy and does not occupy the original space structure of the air conditioner.
