[0002] As people's living standards continue to improve, the air conditioning market is expanding, and more and more families are installing kitchen air conditioners. Due to the effects of oil fumes and moisture in the kitchen, kitchen air conditioners require frequent maintenance. Maintenance often requires opening the electrical box for adjustments. However, kitchen air conditioner indoor units are generally installed on the ceiling (called ceiling-mounted indoor units), making the electrical box difficult to open. For integrated ceiling units, this is even more challenging. Furthermore, after-sales repairs are inconvenient for technicians, resulting in increased difficulty and time, significantly reducing repair efficiency. Utility Model Content

[0041] See 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 vent 12; the fan 6 is disposed inside the housing 1; the electrical box 2 is mounted on the housing 1 and configured to be movable relative to the housing 1 to switch between a first position at least partially above the bottom surface 14 and a second position at least partially below the bottom surface 14. Figure 1 and Figure 2 A three-dimensional structural diagram of the ceiling-mounted air conditioner indoor unit is shown when the electrical box 2 is in the first position (normal working position). Figure 3 A schematic diagram of the structure of a ceiling-mounted air conditioner indoor unit with the electrical box 2 located in the second position (a maintenance position for easy maintenance) is shown.

[0042] When maintenance and adjustment of the electrical box 2 of the ceiling-mounted air conditioner indoor unit are required, the electrical box 2 can be moved to a lower second position for maintenance and adjustment. After the maintenance and adjustment are completed, the electrical box 2 can be moved back to the first position. In the first position, the electrical box 2 is higher than the bottom surface of the casing 1. In the second position, the electrical box 2 is at least partially lower than the bottom surface of the casing 1. Generally, the bottom surface 14 of the ceiling-mounted air conditioner indoor unit is roughly flush with the ceiling. During normal operation, the electrical box 2 is hidden above the ceiling, does not occupy indoor space, and makes the indoor space neater and simpler. When maintenance and adjustment of the electrical box 2 are required, it can be moved to a second position, at least partially below the ceiling, which is convenient for workers to work in. This improves the problem of inconvenient maintenance and adjustment of the electrical box of the ceiling-mounted air conditioner indoor unit in the existing technology. It reduces the difficulty for workers to maintain and adjust the electrical components inside the electrical box 2, which helps to reduce the labor intensity of workers and improve labor efficiency.

[0043] See Figure 1 The ceiling-mounted air conditioner indoor unit of this embodiment also includes a mounting structure 11 disposed on the top of the housing 1. The mounting structure 11 is used to connect to the roof so as to install the air conditioner indoor unit in the ceiling.

[0044] In some embodiments, the electrical box 2 in the second position is lower than the bottom surface 14. The electrical box 2 in the second position is entirely below the bottom surface 14, that is, the electrical box 2 is entirely below the ceiling. After the electrical box 2 is opened, the staff can easily repair and adjust all the electrical components of the electrical box 2, which helps to reduce blind spots in the work area.

[0045] In some embodiments, the electrical box 2 includes an electrical box body 21 with an opening and an electrical box cover 22 covering the opening. See also Figure 1 and 2 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. See also 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. With the opening of the electrical box body 21 facing downwards in the second position, after opening the electrical box cover 22, the staff can easily repair and debug the electrical components inside the electrical box body 21, which reduces the difficulty of repairing and debugging the electrical components inside the electrical box 2, and helps to reduce the labor intensity of the staff and improve labor efficiency.

[0046] In some alternative 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. 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. The opening of the electrical box body 21 faces horizontally, allowing the operator to directly face the inner cavity installed in the electrical box body 21. This facilitates the observation, maintenance, and debugging of the electrical components inside the electrical box 2. The operator can easily maintain and debug the electrical components inside the electrical box body 21, reducing the difficulty of maintenance and debugging, thus reducing the labor intensity and improving labor efficiency. Furthermore, switching between the first and second positions of the electrical box 2 only requires moving the electrical box vertically, which is simple in structure, easy to implement, and low in cost.

[0047] In some embodiments, when the electrical box 2 is in the first position, it is attached to the outer surface of the side wall of the housing 1, and the electrical box cover 22 is located at the end of the electrical box body 21 away from the housing 1. Placing the electrical box 2 outside the housing 1 helps to solve the space problem inside the housing 1 and facilitates the disassembly and maintenance of the electrical box 2. When the electrical box 2 is in the second position, it 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 adjust the electrical components inside the electrical box body 21, reducing the difficulty of repairing and adjusting the electrical components inside the electrical box 2, and helping to reduce the labor intensity and improve the labor efficiency of the staff.

[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 vertically to guide the electrical box 2 from a first position to a second position; the slider 7 is slidably engaged with the guide rail 4 and connected to the electrical box 2. By guiding the electrical box 2 to move vertically through the guide rail 4 and the slider 7, the movement of the electrical box 2 along the ground can be effectively ensured, improving the convenience of switching the position of the electrical box 2, and helping to reduce the labor intensity of maintenance personnel and improve work efficiency.

[0049] The electrical box 2 and the slider 7 are connected by a hinge shaft 9 parallel to the width direction of the guide rail 4, so that after the slider 7 moves to the bottom end of the guide rail 4, the electrical box 2 can rotate toward the bottom surface 14 of the housing 1. See also Figure 9 and Figure 10 When maintenance is required on electrical box 2, the staff first moves electrical box 2 downward along the guide rail. After electrical box 2 is moved to the bottom of guide rail 4, electrical box 2 is rotated around hinge shaft 9 toward the bottom surface of housing 1, thereby rotating electrical box 2 to be attached to the bottom surface of housing 1. At this time, electrical box cover 22 is located at the bottom of electrical box body 21, and the opening of electrical box body 21 in the second position faces downward. After opening electrical box cover 22, the staff can easily repair and debug the electrical components inside electrical box body 21, which reduces the difficulty of repairing and debugging electrical components inside electrical box 2, and helps to reduce the labor intensity of the staff and improve labor efficiency.

[0050] See 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. The plate-shaped 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 perpendicular to the guide rail 4. The plate-shaped 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 vertically and then rotates to the bottom surface of the housing 1 to the second position, the electrical box cover 22 is located at the lower end of the electrical box body 21.

[0051] See Figure 5 and 7 The ceiling-mounted air conditioner indoor unit also 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 after the electrical box 2 moves down to a predetermined position, it can rotate towards the bottom surface of the housing 1.

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

[0053] See 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 restrict the movement of the electrical box 2 relative to the housing 1, thereby positioning the electrical box 2 in the first position. This helps to prevent the electrical box 2 from shaking relative to the housing 1, and thus ensures the reliability of the electrical connection between the electrical components in the electrical box 2 and the electrical parts in the housing 1.

[0054] See Figure 2 The ceiling-mounted air conditioner indoor unit also includes a third connecting structure 15 disposed on the housing 1. The third connecting structure 15 is configured to be detachably connected to the first connecting structure 3, and the third connecting structure 15 has the same structure as the second connecting structure 13. When the electrical box 2 is in the second position, the third connecting structure 15 is connected to the first connecting structure 3 to position the electrical box 2 in the second position, fixing the electrical box 2 in the second position for maintenance and debugging. The electrical box 2 can be wobbled relative to itself, which helps to reduce the difficulty of the workers' work, improve the workers' work efficiency, and ensure the quality of work.

[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 in the first position, and it can also be connected to the third connecting structure 15 to position the electrical box 2 in the second position. By using the same first connecting structure 3 to position the electrical box 2 in both positions, the structure of the air conditioner indoor unit is simplified and the production cost is reduced.

[0056] One of the first connecting structure 3 and the second connecting structure 13 is a snap-fit, and the other is located in a snap-fit ​​structure that matches the snap-fit. In this embodiment, the electrical box 2 is positioned in the first or second position by means of a snap-fit ​​connection. The snap-fit ​​has the advantages of simple structure, low cost and high reliability.

[0057] In some embodiments, the latch includes a cantilever portion 31 and a latching 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 latching portion 32 is connected to the free end of the cantilever portion 31 and extends toward the fixed end. The latching portion 32 is spaced apart from the cantilever portion 31. The latching portion 32 includes a latching protrusion 321 facing away from the cantilever portion 31. The latching portion 32 is configured to approach the cantilever portion 31 under the action of an external force to disengage from the latching structure. The latching portion 32 has the elasticity to return to a predetermined distance from the cantilever portion 31.

[0058] See Figure 5 and Figure 9The fixed end of the cantilever portion 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 channel that allows the insertion of the end of the buckle away from the fixed end of the cantilever portion 31. The channel has a stop portion that cooperates with the stop of the snap-fit ​​protrusion 321. The stop portion is recessed relative to the channel wall to allow the snap-fit ​​protrusion 321 to be inserted. When the buckle is inserted into the channel of the snap-fit ​​structure, the snap-fit ​​protrusion 321 moves closer to the cantilever portion 31. After the buckle is inserted into the snap-fit ​​structure, due to the aforementioned elasticity, the snap-fit ​​portion 32 returns to a position spaced a predetermined distance from the cantilever portion 31 and cooperates with the stop portion of the snap-fit ​​structure. In this embodiment, the buckle is used to connect the electrical box 2 and the housing 1, thereby positioning the electrical box 2 in a first position or a second position. The buckle has the advantages of simple structure, low cost, easy operation, and high reliability.

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

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

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

[0062] During the process of inserting the buckle into the hole of the snap-fit ​​structure, the outer edge of the hole abuts against the guide slope 322 and, as the buckle gradually moves into the snap-fit ​​structure, pushes the snap-fit ​​part 32 towards the cantilever part 31 so that the buckle is inserted into the snap-fit ​​structure to achieve connection with the snap-fit ​​structure. When the operator 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 provided at the end of the snap-fit ​​protrusion 321 away from the guide slope 322, so that the operator can press the snap-fit ​​part 32 toward the cantilever part 31 to disengage the snap-fit ​​protrusion 321 from the snap-fit ​​structure.

[0064] When it is necessary to disconnect the buckle from the snap-fit ​​structure, the operator presses the snap-fit ​​part 32 toward the cantilever part 31 by pressing the pressing structure 323, so that the snap-fit ​​protrusion 321 disengages from the stop of the stop part of the snap-fit ​​structure, thereby allowing the buckle to be pulled out from the hole of the snap-fit ​​structure. It 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 electrical components in the electrical box 2 via a first cable; the second connecting portion is pluggably connected to the first connecting portion and is connected to electrical components in the housing 1 via a second cable.

[0066] The integrated cable uses a plug-in structure (cable connector 5) to facilitate quick plugging and unplugging before moving the electrical box 2, so as to avoid breaking the cable when moving the electrical box 2.

[0067] In some embodiments, the electrical box 2 is provided with a wire-passing hole, and a flexible member 23 is installed on the wire-passing hole. The flexible member 23 has a through hole that allows the first cable to pass through. The flexible member 23 can be made of rubber. This helps to prevent the first cable from being damaged due to friction with a hard component.

[0068] In some embodiments, the ceiling-mounted air conditioner indoor unit is a kitchen indoor unit. Due to the effects of oil fumes and moisture in the kitchen, kitchen air conditioners require frequent maintenance and upkeep. This often necessitates opening the electrical box for adjustments; however, kitchen air conditioner indoor units are typically installed on the ceiling, making the electrical box difficult to access. The ceiling-mounted air conditioner indoor unit of this embodiment effectively solves the problems of frequent maintenance and upkeep required for kitchen air conditioners and the difficulty in opening the electrical box.

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

[0070] First, separate the first and second connecting parts of the cable connector 5 to prevent damage to the cable during the movement of the electrical box 2. See [link / reference]. Figure 2 .

[0071] Then, the connection between the first connecting structure 3 (snap fastener) and the second connecting structure 13 (clamping structure) is released, thereby releasing the electrical box 2 from its first position. Specifically, press the pressing structure 323 of the snap fastener on both sides of the electrical box 2 with both hands, so that the snap fastener is deformed and the clamping protrusion 321 disengages from the stop part of the clamping structure. Then rotate the electrical box 2 and the snap fastener (flip it upwards), so that the snap fastener is disengaged from the slot (second connecting structure 13) provided on the side wall of the housing 1, thereby releasing the electrical box 2 from its first position.

[0072] Then, the electrical box 2 is moved relative to the housing 1. For example... Figure 8 , Figure 9 , Figure 10As shown: The bottom of the electrical box 2 is connected to the guide rail 4 via 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. Limiting components are fixed at both ends of the guide rail 4 to limit the range of movement of the hinge. Since the electrical box 2 is connected to the hinge, the electrical box 2, together with the hinge, moves up and down on the guide rail 4, and is limited at both ends of the guide rail 4. When the hinge and the electrical box 2 move to the lowest limiting block, the hinge and the electrical box 2 will stop moving down. At the same time, the electrical box 2, together with the hinge, is rotated 90 degrees clockwise. After the electrical box 2 is rotated, the two buckles on the side can be engaged into the third connecting part 15 (slot) located on the bottom surface of the housing. Figure 3 , Figure 10 As shown, the electrical box 2 is securely fixed. At this time, 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 for the staff and greatly improve the maintenance efficiency.

[0073] This embodiment provides a novel way to open 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. This makes it convenient to open the electrical box 2 from the bottom when the air conditioner is being repaired and debugged. This will make it easier for staff to carry out repairs and debugging from the bottom, greatly reducing the difficulty of repairs and greatly improving repair efficiency.

[0074] This embodiment achieves the following technical effects:
