Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a ceiling-mounted air conditioner indoor unit and air conditioning equipment. Background Technology

[0002] With social development and the improvement of people's living standards, people have increasingly higher requirements for the environmental quality of the kitchen. Therefore, the kitchen air conditioning market is expanding, and more and more families are installing kitchen air conditioners. However, kitchen air conditioners are easily affected by oil fumes and moisture in the kitchen. They require more frequent maintenance and repairs compared to air conditioners in other rooms. Furthermore, maintenance often requires opening the electrical box for adjustments. The difficulty in disassembling and reassembling the electrical box significantly impacts the efficiency of repair workers. Since most kitchen air conditioner indoor units are installed on the ceiling, opening the electrical box is difficult. For integrated ceiling systems, opening the box is even more challenging, leading to both high operational difficulty and long repair times, greatly reducing the efficiency of repair workers. Utility Model Content

[0003] The present invention aims to provide a ceiling-mounted air conditioner indoor unit and air conditioning equipment to improve the problem that the electrical box of the existing air conditioner indoor unit is inconvenient to maintain.

[0004] According to one aspect of the present invention, a ceiling-mounted air conditioner indoor unit is provided, comprising: a housing having a bottom surface with an air vent; a fan disposed within the housing; and an electrical box including an opening, a bottom wall opposite the opening, and a side wall erected on the bottom wall, the electrical box being configured to be movable relative to the housing to switch between a first position located within the housing and a second position located at least partially outside the housing and below the bottom surface.

[0005] In some embodiments, when the electrical box is in the first position, the opening is located at one end of the electrical box in the horizontal direction; and / or, when the electrical box is in the second position, the opening is located at the bottom end of the electrical box or the opening is located at the same end of the electrical box in the horizontal direction as when the electrical box is in the first position.

[0006] In some embodiments, when the electrical box is in the first position, one end of the electrical box with an opening is attached to the inner surface of the housing so that the opening is sealed by the inner surface of the housing; and / or, when the electrical box is in the second position, the bottom wall of the electrical box is attached to the bottom surface of the housing, and the opening is located at the bottom end of the electrical box.

[0007] In some embodiments, the ceiling-mounted air conditioner indoor unit further includes a guide member connected to the housing and extending in a vertical direction, the guide member being configured to guide the electrical box from a first position to a second position.

[0008] In some embodiments, the electrical box is configured to rotate about a horizontal axis of rotation relative to the guide member so that it can be flipped over to the bottom surface after the electrical box has moved below the bottom surface, so that the bottom wall of the electrical box is attached to the bottom surface.

[0009] In some embodiments, the bottom of the housing is provided with a positioning structure that avoids the electrical box from flipping onto the bottom surface and restricts the rotation of the electrical box in the second position relative to the guide member. The electrical box is configured to move relative to the guide member along the bottom surface when the bottom wall is attached to the bottom surface, so that the electrical box moves to the second position where the rotation relative to the guide member is restricted by the positioning structure.

[0010] In some embodiments, the ceiling-mounted air conditioner indoor unit also includes a movable component configured to move along a guide member, and the electrical box is connected to the movable component via a hinge shaft so that the electrical box can be flipped towards the bottom surface after it has moved below the bottom surface.

[0011] In some embodiments, the electrical box is configured to move relative to the hinge axis in a direction parallel to the bottom surface and perpendicular to the hinge axis, so as to move the electrical box to a second position where rotation is restricted.

[0012] In some embodiments, a slide rail is provided on the side wall of the electrical box, which is movably and rotatably engaged with the hinge shaft. The slide rail is located at one end of the side wall near the bottom wall and extends in a direction parallel to the bottom wall.

[0013] In some embodiments, when the electrical box is in the first position, the slide extends downward from the upper end of the sidewall.

[0014] In some embodiments, a sliding member movable to the guide member is also provided on the side wall of the electrical box. When the electrical box is in the first position, both the sliding member and the slide are configured to move along the length direction of the guide member and are restricted to move along the width direction of the guide member.

[0015] In some embodiments, the ceiling-mounted air conditioner indoor unit further includes a cable connector, which includes: a first connecting portion for connecting to an electrical component in an electrical box via a first cable; and a second connecting portion for pluggable connection to the first connecting portion and for connecting to an electrical component in the housing via a second cable.

[0016] In some embodiments, the ceiling-mounted air conditioner indoor unit is a kitchen air conditioner indoor unit.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

"Vertical" is not vertical in the strict sense, but within the allowable error range. "Parallel" is not parallel in the strict sense, but within the allowable error range.

[0038] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this utility model. It should also be noted in the description of this utility model that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0039] Unless otherwise specified, the terms "comprising" and "including" in this invention can be open-ended or closed-ended. For example, "comprising" and "including" can mean that other components not listed may also be included, or that only the listed components may be included.

[0040] Unless otherwise specified, the term "or" is inclusive in this invention. For example, the phrase "A or B" means "A, B, or both A and B". More specifically, the condition "A or B" is satisfied by any of the following conditions: A is true or exists and B is false or does not exist; A is false or does not exist and B is true or exists; or both A and B are true or exist.

[0041] See Figure 1 and 2The ceiling-mounted air conditioner indoor unit of this embodiment includes a housing 1, a fan 3, and an electrical box 2. The housing 1 has a bottom surface 13 with an air vent 12. The fan 3 is disposed inside the housing 1. The electrical box 2 includes an opening 21, a bottom wall 22 opposite to the opening 21, and a side wall 23 erected on the bottom wall 22. The electrical box 2 is configured to be movable relative to the housing 1 to switch between a first position (normal operating position) located inside the housing 1 and a second position (maintenance position for easy maintenance) located at least partially outside the housing 1 and below the bottom surface 13.

[0042] When it is necessary to repair and debug the electrical box 2 of the ceiling-mounted air conditioner indoor unit, the electrical box 2 can be moved to a second position that is lower and located outside the housing 1 for repair and debugging. After the repair and debugging is completed, the electrical box 2 is moved to the first position. When the electrical box 2 is in the first position, it is higher than the bottom surface 13 of the housing 1 and located inside the housing 1.

[0043] When the electrical box 2 is in the second position, it is at least partially lower than the bottom surface of the housing 1. Generally, the bottom surface 13 of a ceiling-mounted air conditioner indoor unit is roughly flush with the ceiling. During normal operation, the electrical box 2 is hidden inside the housing 1 above the ceiling, not occupying indoor space and making the indoor space neater and simpler. When maintenance or adjustment of the electrical box 2 is 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 upon the problem of inconvenient maintenance and adjustment of the electrical box 2 in existing ceiling-mounted air conditioner indoor units. It reduces the difficulty for workers to maintain and adjust the electrical components inside the electrical box 2, thus reducing labor intensity and improving work efficiency.

[0044] 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.

[0045] In some embodiments, the electrical box 2 located in the second position is lower than the bottom surface 13. The electrical box 2 located in the second position is entirely below the bottom surface 13, 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.

[0046] In some embodiments, when the electrical box 2 is in the first position, the opening 21 is located at one end of the electrical box 2 in the horizontal direction. When the electrical box 2 is in the second position, the opening 21 is located at the bottom end of the electrical box 2, with the opening facing downwards from the housing 1.

[0047] With the opening 21 of the electrical box 2 in the second position facing downwards, after opening the cover 22 of the electrical box, the staff can easily repair and debug the electrical components inside the electrical box 2, 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.

[0048] In some alternative embodiments, when the electrical box 2 is in the first position, the opening 21 is located at one end of the electrical box 2 along the horizontal direction, and when the electrical box 2 is in the second position, the opening 21 is located at the same end of the electrical box 2 along the horizontal direction as when the electrical box 2 is in the first position.

[0049] When the electrical box 2 is in the second position, the opening 21 faces horizontally, allowing workers to directly face the inner cavity of the electrical box 2. This facilitates the observation, maintenance, and debugging of the electrical components inside the electrical box 2, reducing the difficulty of maintenance and debugging and thus reducing labor intensity and improving work efficiency. Furthermore, switching between the first and second positions of the electrical box 2 only requires moving the electrical box 2 vertically, resulting in a simple structure, ease of implementation, and low cost.

[0050] In some embodiments, when the electrical box 2 is in the first position, one end of the electrical box 2 with the opening 21 is attached to the inner surface of the housing 1, so that the opening 21 is sealed by the inner surface of the housing. See [reference needed]. Figure 1 , 4 And 5. When the electrical box 2 is in the second position, the bottom wall 22 of the electrical box 2 is attached to the bottom surface 13 of the housing 1, and the opening 21 is located at the bottom end of the electrical box 2, with the opening 21 facing downwards from the housing 1. See Figure 2 and 10 .

[0051] When the electrical box 2 is in the first position, the opening 21 is covered by the inner surface of the shell to prevent the electrical components inside the electrical box 2 from being bumped by external devices. This helps to prevent various impurities from entering the interior of the electrical box 2 and affecting the normal operation of the electrical components in the electrical box 2.

[0052] When the electrical box 2 is in the second position, the opening 21 faces downwards, allowing staff to easily repair and adjust the electrical components inside the electrical box 2. This reduces the difficulty of repairing and adjusting the electrical components inside the electrical box 2, and helps to reduce the labor intensity of staff and improve labor efficiency.

[0053] In some embodiments, the ceiling-mounted air conditioner indoor unit further includes a guide member 4 connected to the housing 1 and extending in a vertical direction, the guide member 4 being configured to guide the electrical box 2 from a first position to a second position.

[0054] By guiding the electrical box 2 to move vertically through the guide component 4, it is possible to effectively ensure that the electrical box 2 moves along the ground, improve the convenience of switching the position of the electrical box 2, and help reduce the labor intensity of maintenance and debugging personnel and improve work efficiency.

[0055] In some embodiments, the electrical box 2 is configured to rotate about a horizontal axis of rotation relative to the guide member 4, so that after the electrical box 2 moves below the bottom surface 13, it can be flipped toward the bottom surface 13 so that the bottom wall of the electrical box 2 is attached to the bottom surface 13.

[0056] With the electrical box 2 attached to the bottom surface 13 of the housing 1 and its opening 21 facing downwards, workers can easily repair and adjust the electrical components inside the electrical box 2. This reduces the difficulty of repairing and adjusting the electrical components inside the electrical box 2, thereby reducing the labor intensity and improving work efficiency. Furthermore, attaching the electrical box 2 to the bottom surface 13 of the housing 1 also facilitates the fixation of the electrical box 2. For example, the electrical box 2 can be connected to the bottom surface 13 using snap-fit ​​connections, hook connections, or other methods that facilitate easy separation and connection. Fixing the electrical box 2 in the second position for repair and adjustment allows it to move slightly, which helps reduce the difficulty of the worker's work, improves work efficiency, and ensures work quality.

[0057] In some embodiments, the bottom of the housing 1 is provided with a positioning structure 14 that avoids the electrical box 2 from flipping toward the bottom surface 13 and restricts the rotation of the electrical box 2 relative to the guide member 4 in the second position. The electrical box 2 is configured to move along the bottom surface 13 relative to the guide member 4 when the bottom wall 22 is attached to the bottom surface 13, so that the electrical box 2 moves to the second position where the rotation relative to the guide member 4 is restricted by the positioning structure 14.

[0058] In this embodiment, simply moving or rotating the electrical box 2 is sufficient to switch it from the first position hidden inside the housing 1 to the second position fixed below the housing 1. This simple operation improves the efficiency of maintenance and debugging of the electrical box 2.

[0059] During the process of switching the electrical box 2 from the first position to the second position, firstly, the electrical box 2 is moved downward along the guide member 4 to a predetermined position at the lower end of the guide member 4, see [link to relevant documentation]. Figures 4 to 6 Then, flip the electrical box 2 towards the bottom surface 13 of the housing 1 (see...). Figure 7 The bottom wall 22 of the electrical box 2 is attached to the bottom surface 13 of the housing 1 (see...). Figure 8 and 9 Next, move the electrical box 2 along the bottom surface 13 of the housing 1 to a position that mates with the positioning structure 14 (see...). Figure 10 and Figure 11 ).

[0060] Furthermore, the positioning structure 14 can be the bottom surface 13 of the housing 1, the side of the housing 1, or other components of the air conditioner indoor unit. Preferably, the positioning structure 14 is a component that is not higher than the bottom surface 13 of the housing 1, so as to improve the compactness of the air conditioner indoor unit.

[0061] In some embodiments not shown, the bottom surface 13 of the housing 1 is provided with an outlet that is adapted to the size of the electrical box 2. The electrical box 2 extends downward from the outlet of the housing 1 and flips to be attached to the bottom surface 13 of the housing 1. After it moves or rotates relative to the outlet, the outer edge of the outlet of the bottom surface 13 can restrict the electrical box 2 from rotating again, thereby fixing the electrical box 2 relative to the housing 1.

[0062] In some embodiments, the ceiling-mounted air conditioner indoor unit also includes a movable component 5 configured to move along the guide component 4, and the electrical box 2 is connected to the movable component 5 via a hinge shaft 6 so that the electrical box 2 can be flipped toward the bottom surface 13 after it moves below the bottom surface 13.

[0063] With the electrical box 2 attached to the bottom surface 13 of the housing 1 and the opening 21 facing downwards, workers can easily repair and adjust the electrical components inside the electrical box 2. This reduces the difficulty of repairing and adjusting the electrical components inside the electrical box 2, and helps to reduce the labor intensity and improve work efficiency. Furthermore, attaching the electrical box 2 to the bottom surface 13 of the housing 1 also facilitates the fixing of the electrical box 2, for example, by connecting the electrical box 2 to the bottom surface 13.

[0064] The cooperation between the moving part 5 and the guiding part 4, as well as the rotatable connection achieved through the hinge shaft 6, are all mature, stable, and reliable connection structures. The simple structure allows the electrical box 2 to be flipped to the bottom surface 13, which helps to simplify the structure of the air conditioner indoor unit and improve the reliability and stability of the air conditioner indoor unit.

[0065] In some embodiments, the electrical box 2 is configured to move relative to the hinge shaft 6 in a direction parallel to the bottom surface 13 and perpendicular to the hinge shaft 6, so that the electrical box 2 moves to a second position where rotation is restricted.

[0066] The hinge shaft 6 is used to both flip the electrical box 2 and move the electrical box 2 along the bottom surface of the housing 1 to the bottom of the positioning structure 14, which simplifies the structure of the air conditioner indoor unit and helps to improve assembly efficiency and reduce costs.

[0067] See Figure 3As shown in sections 6 to 9, the indoor unit of the air conditioner includes two guide components 4 spaced apart along a first direction. The two guide components 4 are respectively arranged on both sides of the electrical box 2, with the electrical box 2 located between the two guide components 4. Each guide component 4 is provided with a moving component 5, and each moving component 5 is connected to a hinge shaft 6. The two hinge shafts 6 extend from the corresponding moving component 5 toward two opposite side walls 23 of the electrical box 2, and are hinged to the two opposite side walls 23 of the electrical box 2. The axial directions of the two hinge shafts 6 are both parallel to the first direction, and the two hinge shafts 6 are coaxial.

[0068] In some embodiments, after the electrical box 2 is flipped toward the bottom surface of the housing 1, it moves along a second direction perpendicular to the hinge axis 6, so that one end of the electrical box 2 along the second direction is located below the positioning structure 14, and is restricted from rotating upward by the positioning structure 14, thereby achieving a state where it is fixed in the housing 1. This facilitates the maintenance and adjustment of the electrical box by the operator. See [reference needed]. Figure 8 .

[0069] The side wall 23 of the electrical box 2 is provided with a slide 24 that is movably engaged with the hinge shaft 6 and can rotate relatively low. The slide 24 is located at one end of the side wall 23 near the bottom wall 22 and extends in a direction parallel to the bottom wall 22.

[0070] The slide 24 does not have a structure to restrict the rotation of the hinge shaft 6. The hinge shaft 6 can move relative to the slide 24 and can also rotate relative to the slide 24, thereby realizing the flipping of the electrical box 2 and its movement in the second direction. It has the advantages of simple structure and high reliability.

[0071] Furthermore, the slide 24 is located at one end of the bottom wall 22. During the flipping process of the electrical box 2 towards the housing 1, it experiences less constraint, making it easier to achieve the fit between the bottom wall 22 of the electrical box 2 and the bottom surface 13 of the housing 1. (See [reference]) Figure 7 and 8 .

[0072] In this embodiment, when the electrical box 2 is in the first position, the slide 24 extends downward from the upper end of the side wall 23. After the electrical box 2 moves downward below the bottom surface of the housing 1, see... Figure 5 and 6 The hinge shaft 6 is connected to the side wall 23 of the electrical box 2 at one corner of the side wall 23. During the process of the electrical box 2 flipping towards the housing 1, it is subject to less constraint, making it easier to make the bottom wall 22 of the electrical box 2 fit with the bottom surface 13 of the housing 1.

[0073] See Figure 5 and Figure 6The side wall 23 of the electrical box 2 is also provided with a sliding member 25 that is movable with the guide member 4. When the electrical box 2 is in the first position, both the sliding member 25 and the slide rail 24 are configured to move along the length direction of the guide member 4 and are restricted to move along the width direction of the guide member 4. The width direction of the guide member 4 is consistent with the direction (second direction) in which the electrical box 2 moves along the bottom surface of the housing 1.

[0074] When the electrical box 2 is in the first position, the sliding component 25 and the slide rail 24 work together to restrict the electrical box 2 from shaking along the second direction of the guide component 4. The guide components 4 at both ends of the electrical box 2 along one direction restrict the electrical box 2 from shaking along the first direction, thereby fixing the electrical box 2 and preventing damage to the electrical components inside the electrical box 2 and the cables connected to it due to shaking. This helps to ensure the stable operation of the indoor unit of the air conditioner.

[0075] The lower end of the guide member 4 is configured to allow the sliding member 25 to disengage from the guide member 4. When the electrical box 2 is in the first position, the sliding member 25 is located below the slide rail 24. During the downward movement of the electrical box 2, the sliding member 25 disengages from the lower end of the guide member 4.

[0076] See Figure 1 The electrical box 2, which is in the first position, is also connected to the housing 1 via a threaded connector 7 to prevent the electrical box 2 from moving downwards due to gravity.

[0077] See Figure 3 In this embodiment, the guide component 4 includes an annular component with a longitudinal section parallel to the length direction of the guide component 4. The moving component 5 includes a columnar component perpendicular to the guide component 4. The columnar component is fitted inside the annular component and configured to move along the length direction of the guide component 4. A strip-shaped opening 41 extending along the length direction of the annular component is provided in the middle of the width direction of the annular component. The hinge shaft 6 is connected to the columnar component and extends out of the strip-shaped opening to cooperate with the slide rail 24 of the electrical box 2. The hinge shaft 6 and the columnar component form a T-shaped component. The strip-shaped opening 41 extends to the lower end face of the annular component to facilitate the disengagement of the sliding component 25 from the annular component.

[0078] The ceiling-mounted air conditioner indoor unit also includes a cable connector, which includes a first connecting part and a second connecting part. The first connecting part is connected to the electrical components in the electrical box 2 via a first cable; the second connecting part is pluggably connected to the first connecting part and is connected to the electrical components in the housing 1 via a second cable.

[0079] The integrated cable uses a plug-in structure (cable connector) 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.

[0080] The ceiling-mounted air conditioner indoor unit also includes a panel covering the bottom surface 13 of the housing 1. The panel is detachably connected to the housing 1. When the electrical box 2 needs to be repaired or adjusted, the panel needs to be removed, and then the electrical box 2 can be moved to the outside of the housing 1 by moving the electrical box 2, which helps to improve work efficiency and reduce labor intensity.

[0081] To address these issues, we propose a solution and design to overcome the difficulty of opening the electrical box. This innovative approach to opening the electrical box, utilizing guide component 4, facilitates easy opening during air conditioner maintenance and adjustments. Furthermore, once opened, the electrical box faces the staff, allowing for easier maintenance and adjustments from below, significantly improving staff efficiency.

[0082] In some embodiments, the ceiling-mounted air conditioner indoor unit is a kitchen air conditioner 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.

[0083] The ceiling-mounted air conditioner indoor unit of this embodiment helps to solve the problems of kitchen air conditioner indoor units requiring frequent maintenance and upkeep, as well as the difficulty in opening the electrical box.

[0084] This embodiment provides a solution and design to address the difficulty in opening the electrical box 2. It innovates the opening method of the electrical box 2 and utilizes the guide component 4 to facilitate opening the electrical box 2 during air conditioner maintenance and debugging. Furthermore, once opened, the electrical box 2 faces the workers, allowing for easier maintenance and debugging from below, greatly improving maintenance efficiency. The specific implementation method is as follows:

[0085] The indoor unit of an air conditioner includes a housing 1, a fan 3 housed within the housing 1, an electrical box 2, a guide component 4, a threaded connector 7, and a mounting structure 11. The electrical box 2, guide component 4, threaded connector 7, and mounting structure 11 are as follows: Figure 1 and Figure 3 As shown.

[0086] Figure 1 This is a schematic diagram of the installation position of the electrical box 2 in the indoor unit of the air conditioner. The indoor unit of the air conditioner is mainly composed of a housing 1, a fan 3, an electrical box 2, a guide component 4, a threaded connector 7 (e.g., screws), and an installation structure 11 (e.g., hooks). At this time, the two threaded connectors 7 are used to fasten the electrical box 2.

[0087] Figure 4This diagram illustrates the process of releasing the electrical box 2 from its fixed position. After removing the two threaded connectors 7, the electrical box 2 can be pulled out of the indoor air conditioner unit. This diagram shows the electrical box 2 moving downwards along the guide member 4. The two sliding parts 25 at the bottom of the electrical box 2 disengage from the guide member 4. For detailed structural information, please refer to [link to diagram]. Figures 5 to 6 ;

[0088] Figure 5 and Figure 6 This is a schematic diagram showing the electrical box 2 moving downwards along the guide component 4. Additionally... Figure 5 and Figure 6 The guide mechanism of the electrical box 2 is also partially shown, revealing the structural details of the guide component 4. (See also...) Figure 3 The guiding mechanism of the guide component 4 consists of a guide component 4, a T-shaped component, a sliding component 25, and a slide rail 24. The guide component 4 is fixed inside the housing 1 of the indoor unit of the air conditioner. The slide rail 24 is set on both sides of the electrical box 2. The slide rail 24 and the guide component 4 are connected by the T-shaped component. Therefore, the entire electrical box 2 is connected and guided by the slide rail 24, the T-shaped component, and the guide component 4. The T-shaped component can move up and down in the guide component 4 and the slide rail 24 respectively. The guide component 4 and the slide rail 24 will limit the movement range of the T-shaped component, and at the same time limit the movement range of the electrical box 2. After the electrical box 2 moves to below the guide component 4, due to the cooperation of the T-shaped component and the guide component 4, the electrical box 2 will be restricted from moving downward.

[0089] Figure 3 The diagram shows the details of the T-shaped component moving within the guide component 4 and explains the principle by which the sliding component can disengage from the guide component 4. The sliding component is guided along the inner side of the guide component 4 and can disengage from the opening at the lower end of the guide component 4. In addition, the T-shaped component is guided along the annular inner side of the guide component 4 and will be restricted to move within the annular component.

[0090] Figure 7 This is a schematic diagram of the electrical box 2 rotating clockwise, where the slides 24 on both sides of the electrical box 2 will cooperate with the T-shaped component to enable the electrical box 2 to rotate around the hinge axis 6 of the T-shaped component.

[0091] Figure 8 and 9 This is a schematic diagram of the electrical box 2 after it has been rotated 90 degrees clockwise. At this time, the electrical box 2 and the slides 24 on both sides of the electrical box 2 will cooperate with the T-shaped component to enable the electrical box 2 to move to the left.

[0092] Figure 10 and 11This is a schematic diagram showing the electrical box 2 after it has moved to the left. At this point, the electrical box 2 is at its leftmost position, and its movement is restricted by the slide rail 24. Furthermore, since the bottom of the electrical box 2 is pressed against the indoor unit of the air conditioner, it is fixed in this position. This state allows for maintenance by personnel. Note: Figure 1 The indoor unit of the air conditioner is shown with the mounting structure 11 facing downwards. This is to facilitate the demonstration of the electrical box 2's structure. However, in actual installation, the indoor unit is suspended from above by the mounting structure 11. The actual suspended state of the indoor unit can be seen in the image below. Figure 2 .

[0093] Figure 2 The diagram shows the indoor unit of the air conditioner viewed from below. As you can see, the opening of the electrical box 2 is facing downwards, making it easier for staff to perform maintenance from below.

[0094] The specific process of moving the electrical box 2 is as follows:

[0095] The process of removing the electrical box 2 from the indoor unit of the air conditioner is as follows: Figure 4 As shown: Remove the two threaded connectors 7. At this time, the electrical box 2 will be released from its fixed position and can be moved. Then, pull the electrical box 2 out of the air conditioner indoor unit. This figure shows the process of the electrical box 2 moving upward along the guide component 4. The two sliding parts at the bottom of the electrical box 2 come out from the opening below the guide component 4.

[0096] The process of moving electrical box 2 from the indoor unit of the air conditioner is as follows: Figures 4 to 6 As shown: the guide component 4 is fixed inside the housing 1 of the indoor unit of the air conditioner, and the slide 24 is fixed on both sides of the electrical box 2. The slide 24 and the guide component 4 are connected by a T-shaped component. Therefore, the entire electrical box 2 is connected and guided by the slide 24, the T-shaped component and the outer guide component 4. The T-shaped component can move up and down in the guide component 4 and the slide 24 respectively. The guide component 4 and the slide 24 will limit the movement range of the T-shaped component, and at the same time limit the movement range of the electrical box 2. After the electrical box 2 moves above the guide component 4, due to the cooperation of the T-shaped component and the guide component 4, the electrical box 2 will be restricted from moving upward.

[0097] The process of flipping electrical box 2 on the indoor unit of the air conditioner is as follows: Figures 7 to 9 As shown: The slides 24 on both sides of the electrical box 2 will cooperate with the T-shaped component, enabling the electrical box 2 to rotate around the hinge axis 6 of the T-shaped component, and the electrical box 2 to rotate 90 degrees clockwise.

[0098] The process of fixing the electrical box 2 to the indoor unit of the air conditioner is as follows: Figures 9 to 11As shown: After the electrical box 2 is rotated 90 degrees, the electrical box 2 is moved to the left. When the electrical box 2 is moved to the leftmost position, the movement of the electrical box 2 will be restricted by the slide 24. This is because the upward movement of the electrical box 2 will be restricted by the guide component 4, and the downward movement will also be restricted because the bottom surface of the electrical box 2 is close to the housing 1 of the air conditioner indoor unit or other components. The electrical box 2 is in a state where it can be maintained by the staff.

[0099] With the electrical box 2 securely fixed, staff can now open the cover of the electrical box 2 on the indoor air conditioner unit below for repairs and adjustments. This will greatly reduce the difficulty of repairs and significantly improve repair efficiency.

[0100] The indoor air conditioner unit of this embodiment achieves the following technical effects:

[0101] 1. By setting a slide rail 24 and a guide component 4 on the electrical box 2, the electrical box 2 hidden inside the air conditioner indoor unit can be pulled out, and the electrical box 2 is opened to face the maintenance personnel, which is convenient for the maintenance personnel to carry out maintenance and debugging.

[0102] 2. Through the guiding mechanism composed of the new type of guide component 4, slide 24 and T-shaped component, the electrical box 2 can be pulled out from the housing 1 and can be rotated 90 degrees, so that the electrical box 2 can be rotated to a direction that is convenient for maintenance and debugging.

[0103] 3. Through the innovative design of the slide 24, the electrical box 2 can be self-fixed after being pulled out, without the need for additional fasteners. Moreover, the installation is firm, which will greatly facilitate maintenance personnel in maintenance and debugging and improve maintenance efficiency.

[0104] 4. The structure that enables the electrical box 2 to move, flip, and self-fix is ​​simple and reliable, and the structure is ingenious and flexible. When the electrical box is opened, it can be flipped to the bottom of the air conditioner indoor unit for easy maintenance; when the electrical box is retracted, it can continue to hide the interior of the air conditioner indoor unit, thus not changing the original appearance.

[0105] According to another aspect of this application, an air conditioning device is also provided, which includes the above-described ceiling-mounted air conditioning indoor unit.

[0106] The above description is only an exemplary embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
