Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a ceiling-mounted air conditioning indoor unit and air conditioning equipment. Background Art

[0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the quality of the kitchen environment, so the kitchen air conditioner market is becoming more and more open, and more and more families are installing kitchen air conditioners in the kitchen. However, kitchen air conditioners are currently easily affected by the smoke and water vapor in the kitchen. The number and frequency of maintenance and repair required for kitchen air conditioners are more than those in other rooms, and the electrical box of the air conditioner often needs to be opened for debugging during maintenance and repair. Therefore, the difficulty of disassembling and assembling the electrical box of the kitchen air conditioner will greatly affect the maintenance efficiency of the staff. However, the indoor unit of the kitchen air conditioner on the market is generally installed above the ceiling, which makes it difficult to open the electrical box. It will be even more difficult to open the integrated ceiling for debugging. The operation is difficult and the maintenance time is long, which greatly reduces the maintenance efficiency of the staff. Summary of the invention

[0003] The present invention aims to provide a ceiling-mounted air-conditioning indoor unit and air-conditioning equipment, so as to improve the problem in the prior art that the electrical box of the air-conditioning indoor unit is inconvenient to maintain.

[0004] According to one aspect of an embodiment of the present invention, the present invention provides a ceiling-mounted air-conditioning indoor unit, which includes: a shell having a bottom surface provided with an air outlet; a fan disposed in the shell; and an electrical box, including an opening, a bottom wall opposite to the opening, and a side wall upright on the bottom wall, wherein the electrical box is configured to be movable relative to the shell to switch between a first position located inside the shell and a second position at least partially located outside the shell and below the bottom surface.

[0012] In some embodiments, a slideway is disposed on the side wall of the electrical box and is movably and relatively rotatably matched with the hinge shaft. The slideway is disposed at one end of the side wall close to the bottom wall and extends in a direction parallel to the bottom wall.

[0013] In some embodiments, when the electrical box is located at the first position, the slide extends downward from the upper end of the side wall.

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

[0015] In some embodiments, the ceiling-mounted air conditioner indoor unit also includes a cable connector, which includes: a first connecting part, which is connected to the electrical components in the electrical box through a first cable; a second connecting part, which is pluggably connected to the first connecting part and connected to the electrical components in the shell through a second cable.

For example, "include" and "comprising" may represent that other components not listed may also be included or may only include or comprise the listed components.

[0040] If not specifically stated, in the present invention, the term "or" is inclusive. For example, the phrase "A or B" means "A, B, or both A and B". More specifically, any of the following conditions satisfies the condition "A or B": 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 also 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 outlet 12. The fan 3 is arranged in 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 vertically arranged 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 working position) located in the housing 1 and a second position (maintenance position for easy maintenance) at least partially located 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-conditioning indoor unit, the electrical box 2 can be moved to a second position that is lower and located outside the shell 1 for repair and debugging work. After the repair and debugging work is completed, the electrical box 2 is moved to the first position, wherein the electrical box 2 is higher than the bottom surface 13 of the shell 1 and is located inside the shell 1 when it is in the first position.

[0043] When the electrical box 2 is located at the second position, at least part of it is lower than the bottom surface of the housing 1. Generally, the bottom surface 13 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 inside the housing 1 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 the second position at least partly located below the ceiling, which is convenient for the staff to work, thereby improving the problem that the electrical box 2 of the indoor unit of the ceiling-mounted air conditioner in the prior art is not convenient for repair and debugging. It 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 the labor efficiency.

[0044] 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.

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

[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 of the electrical box 2 and faces the bottom of the housing 1.

[0047] The opening 21 of the electrical box 2 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 2, which reduces the difficulty of repairing and debugging the electrical components in the electrical box 2 for the staff, and is conducive to reducing the labor intensity of the staff and improving labor efficiency.

[0048] In other optional 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 is oriented in the horizontal direction, and the staff can directly face the inner cavity installed in the electrical box 2, which is convenient for observing and repairing and debugging the electrical components in the electrical box 2, reducing the difficulty of the staff in repairing and debugging the electrical components in the electrical box 2, which is conducive to reducing the labor intensity of the staff and improving the labor efficiency. Furthermore, the electrical box 2 can be switched between the first position and the second position only by moving the electrical box 2 in the vertical direction, which has the characteristics of simple structure, easy 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 having the opening 21 is attached to the inner surface of the housing 1 so that the opening 21 is covered by the inner surface of the housing, see Figure 1 , 4 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, and the opening 21 faces the bottom of 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 in the electrical box 2 from being hit by external devices, which is beneficial to prevent various impurities from entering the interior of the electrical box 2 and affecting the normal operation of the electrical components of the electrical box 2.

[0052] When the electrical box 2 is in the second position, the opening 21 faces downward, and the staff can conveniently repair and debug the electrical components in the electrical box 2, which reduces the difficulty of repairing and debugging the electrical components in the electrical box 2 for the staff, and is conducive to reducing the labor intensity of the staff and improving labor efficiency.

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

[0054] By guiding the electrical box 2 to move in the vertical direction through the guide component 4, the electrical box 2 can be effectively ensured to move along the field, which improves the convenience of switching the position of the electrical box 2, is conducive to reducing the labor intensity of maintenance and debugging personnel and improving work efficiency.

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

[0056] The electrical box 2 is attached to the bottom surface 13 of the housing 1 with the opening 21 facing downward, so that the staff can easily repair and debug the electrical components in the electrical box 2, 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 the labor efficiency. Further, attaching the electrical box 2 to the bottom surface 13 of the housing 1 is also conducive to fixing the electrical box 2, for example, the electrical box 2 is connected to the bottom surface 13, and the connection between the electrical box 2 and the bottom surface 13 can be a snap connection, a hook connection, etc., which is easy to separate and connect. The electrical box 2 is fixed in 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 the staff's work, improving the staff's work efficiency, and ensuring the quality of work.

[0057] In some embodiments, a positioning structure 14 is provided at the bottom of the shell 1 to prevent the electrical box 2 from flipping toward the bottom surface 13 and to limit the rotation of the electrical box 2 at the second position relative to the guide component 4. The electrical box 2 is configured to be able to move along the bottom surface 13 relative to the guide component 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 it is limited by the positioning structure 14 from rotating relative to the guide component 4.

[0058] In this embodiment, the electrical box 2 can be switched from the first position hidden in the shell 1 to the second position fixed below the shell 1 only by moving or rotating it, which has the characteristics of simple operation and is conducive to improving the maintenance and debugging efficiency of the electrical box 2.

[0059] In the process of switching the electrical box 2 from the first position to the second position, first, the electrical box 2 is moved downward along the guide member 4 to a predetermined position along the lower end of the guide member 4, see Figures 4 to 6 Then, the electrical box 2 is turned toward the bottom surface 13 of the housing 1 (see Figure 7 ) to the bottom wall 22 of the electrical box 2 attached to the bottom surface 13 of the housing 1 (see Figure 8 and 9 ), and then, move the electrical box 2 along the bottom surface 13 of the housing 1 to a position that matches the positioning structure 14 (see Fig.10 and Fig.11 ).

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

[0061] In some embodiments not shown, an outlet adapted to the size of the electrical box 2 is provided on the bottom surface 13 of the shell 1. After the electrical box 2 extends downward from the shell 1 from the outlet and is flipped over to be attached to the bottom surface 13 of the shell 1, and then moves or rotates relative to the outlet, the outer edge of the outlet on the bottom surface 13 can limit the rotation of the electrical box 2, thereby fixing the electrical box 2 relative to the shell 1.

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

[0063] By attaching the electrical box 2 to the bottom surface 13 of the housing 1 with the opening 21 facing downward, the staff can conveniently repair and debug the electrical components in the electrical box 2, which reduces the difficulty of the staff in repairing and debugging the electrical components in the electrical box 2, and is conducive to reducing the labor intensity of the staff and improving labor efficiency. Furthermore, attaching the electrical box 2 to the bottom surface 13 of the housing 1 is also conducive to fixing the electrical box 2, for example, connecting the electrical box 2 to the bottom surface 13.

[0064] The cooperation between the moving part 5 and the guide part 4 and the rotatable connection achieved through the hinge shaft 6 are both connection structures with high maturity, good stability and reliable operation. The electrical box 2 can be flipped toward the bottom surface 13 through a simple structure, which is conducive to simplifying the structure of the air-conditioning indoor unit and improving the reliability and stability of the air-conditioning indoor unit.

[0065] In some embodiments, the electrical box 2 is configured to be movable relative to the hinge shaft 6 in a direction parallel to the bottom surface 13 and perpendicular to the axis of 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 realize the flipping of the electrical box 2 and to realize the movement of the electrical box 2 along the bottom surface of the shell 1 to the bottom of the positioning structure 14, which simplifies the structure of the air conditioner indoor unit, helps to improve assembly efficiency and reduce costs.

[0067] See also Figure 3And 6 to 9, the air conditioner indoor unit includes two guide components 4 arranged at intervals along the first direction, the two guide components 4 are arranged on both sides of the electrical box 2, the electrical box 2 is located between the two guide components 4, each guide component 4 is provided with a moving component 5, each moving component 5 is connected with a hinge shaft 6, the two hinge shafts 6 are respectively extended from the corresponding moving components 5 toward the two opposite side walls 23 of the electrical box 2, and the two hinge shafts 6 are respectively hinged to the two opposite side walls 23 of the electrical box 2. Among them, the axial directions of the two hinge shafts 6 are 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 the second direction perpendicular to the hinge shaft 6, and then one end of the electrical box 2 along the second direction is located below the positioning structure 14, so that it is restricted by the positioning structure 14 to rotate upward, thereby reaching a state where it is fixed to the housing 1, achieving the effect of facilitating the maintenance and debugging of the electrical box by the staff, see Figure 8 .

[0069] The side wall 23 of the electrical box 2 is provided with a slideway 24 that is movably and relatively rotatably matched with the hinge shaft 6 . The slideway 24 is provided at one end of the side wall 23 close to the bottom wall 22 and extends in a direction parallel to the bottom wall 22 .

[0070] There is no structure in the slideway 24 to limit the rotation of the hinge shaft 6. The hinge shaft 6 can move relatively along the slideway 24 and can also rotate relatively in the slideway 24, thereby realizing the flipping of the electrical box 2 and moving along the second direction, which has the advantages of simple structure and high reliability.

[0071] Furthermore, the slideway 24 is disposed at one end of the bottom wall 22, and during the flipping process of the electrical box 2 toward the housing 1, the electrical box 2 is less constrained, and it is easy to achieve the fit between the bottom wall 22 of the electrical box 2 and the bottom surface 13 of the housing 1, see Figure 7 and 8 .

[0072] In this embodiment, when the electrical box 2 is located at the first position, the slideway 24 extends downward from the upper end of the side wall 23. After the electrical box 2 moves downward to the bottom 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 a corner of the side wall 23. During the flipping process of the electrical box 2 toward the shell 1, there are fewer constraints, and it is easy to achieve the fit between the bottom wall 22 of the electrical box 2 and the bottom surface 13 of the shell 1.

[0073] See also Figure 5 and Figure 6A sliding member 25 movable with the guide member 4 is also provided on the side wall 23 of the electric box 2. When the electric box 2 is in the first position, the sliding member 25 and the slideway 24 are both 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 electric 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 24 cooperate to limit the electrical box 2 from shaking in the second direction of the guide component 4, and the guide components 4 at both ends of the electrical box 2 along one direction limit the electrical box 2 from shaking in the first direction, thereby fixing the electrical box 2 and preventing the electrical components in the electrical box 2 and the cables connected thereto from being damaged due to shaking, which is beneficial to ensuring the stable movement of the air conditioner indoor unit.

[0075] The lower end of the guide component 4 is configured to allow the sliding component 25 to detach from the guide component 4. When the electrical box 2 is in the first position, the sliding component 25 is located below the slide 24. When the electrical box 2 moves downward, the sliding component 25 detaches from the lower end of the guide component 4.

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

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

[0078] The ceiling-mounted air conditioner indoor unit also includes a cable connector, 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.

[0079] The integrated cables use a plug-in connector structure (cable connector), 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.

[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 and debugged, 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 is beneficial to improving work efficiency and reducing labor intensity.

[0081] In order to solve these problems, we proposed a solution and design to solve the problem of difficulty in opening the electrical box, innovated the way of opening the electrical box, and used the guide component 4 to guide the electrical box, so that the electrical box is easy to open when repairing and debugging the air conditioner. After the electrical box is opened, it can face the staff, which will facilitate the staff to carry out repairs and debugging below, greatly improving the maintenance efficiency of the staff.

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

[0083] The ceiling-mounted air-conditioning indoor unit of this embodiment is helpful in solving the problem that the kitchen air-conditioning indoor unit needs frequent care and maintenance and the electrical appliance box is difficult to open.

[0084] This embodiment provides a solution and design to solve the problem of difficulty in opening the electrical box 2, innovates the opening method of the electrical box 2, and uses the guide component 4 to guide, so that the electrical box 2 is easy to open when the air conditioner is repaired and debugged, and the electrical box 2 can face the staff after opening, which will facilitate the staff to perform maintenance and debugging below, greatly improving the maintenance efficiency of the staff. The specific implementation method is as follows:

[0085] The air conditioner indoor unit comprises a housing 1, a fan 3 arranged in the housing 1, an electrical box 2, a guide component 4, a threaded connector 7, a mounting structure 11, an electrical box 2, a guide component 4, a threaded connector 7 and a mounting structure 11, as shown in FIG. Figure 1 and Figure 3 shown.

[0086] Figure 1 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 mainly consists of a housing 1, a fan 3, an electrical box 2, a guide component 4, a threaded connector 7 (such as a screw), a mounting structure 11 (such as a hook), etc. At this time, two threaded connectors 7 are used to fasten the electrical box 2;

[0087] Figure 4This is a schematic diagram of releasing the fixing of the electrical box 2. After removing the two threaded connectors 7, the electrical box 2 can be pulled out of the air conditioner indoor unit. This figure shows the process of the electrical box 2 moving downward along the guide component 4, in which the two sliding components 25 at the bottom of the electrical box 2 are disengaged from the guide component 4. The specific structural details are shown in Figures 5 to 6 ;

[0088] Figure 5 and Figure 6 is a schematic diagram of the electrical box 2 moving downward along the guide member 4. Figure 5 and Figure 6 The guide mechanism of the electrical box 2 is also partially shown, and the structural details of the guide component 4 are shown. Figure 3 The guide mechanism of the guide component 4 is composed of a guide component 4, a T-shaped component, a sliding component 25, and a slide 24, wherein the guide component 4 is fixed to the inner side of the housing 1 of the air-conditioning indoor unit, and the slide 24 is arranged on both sides of the electrical box 2. The slide 24 and the guide component 4 are connected by the T-shaped component, so the entire electrical box 2 is connected and guided by the slide 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 24 respectively. The guide component 4 and the slide 24 will limit the moving range of the T-shaped component, and will also limit the moving range of the electrical box 2. After the electrical box 2 moves to the bottom of 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 figure shows the details of the T-shaped component moving in the guide component 4, and introduces the principle that the sliding component can escape from the guide component 4, wherein the sliding component is guided along the inner side of the guide component 4, and the sliding component can escape 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 the T-shaped component will be restricted from moving in the annular component.

[0090] Figure 7 It is a schematic diagram of the electrical box 2 turning clockwise, wherein the slideways 24 on both sides of the electrical box 2 will cooperate with the T-shaped component to enable the electrical box 2 to turn around the hinge shaft 6 of the T-shaped component.

[0091] Figure 8 and 9 This is a schematic diagram of the electrical box 2 after being turned 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] Fig.10 and 11This is a schematic diagram of the electrical box 2 after it moves to the left. At this time, the electrical box 2 is moved to the leftmost position. At this moment, the electrical box 2 is restricted by the slide 24, and because the bottom surface of the electrical box 2 is close to the air conditioner indoor unit, the electrical box 2 will be fixed here. In this state, the electrical box 2 can be repaired by the staff. Figure 1 The direction of the air conditioner indoor unit is shown as the mounting structure 11 in the downward direction, which is to facilitate the display of the structure of the electrical box 2. When the air conditioner indoor unit is actually installed, it is suspended from the upper part by the mounting structure 11. The actual hanging state of the air conditioner indoor unit is shown in FIG. Figure 2 .

[0093] Figure 2 This is a schematic diagram of looking upward at the indoor unit of the air conditioner. It can be seen that the opening of the electrical box 2 is downward at this time, which is convenient for the 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 air conditioner indoor unit is as follows: Figure 4 As shown: remove the two threaded connectors 7, the electrical box 2 will be released and can be moved. At this time, the electrical box 2 is pulled out from the air-conditioner indoor unit. This figure shows the process of the electrical box 2 moving upward along the guide component 4, in which the two sliding components at the bottom of the electrical box 2 are disengaged from the opening below the guide component 4.

[0096] The process of moving the electrical box 2 from the air conditioner indoor unit is as follows: Figures 4 to 6 As shown: the guide component 4 is fixed on the inner side of the housing 1 of the air conditioner indoor unit, 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, so 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 will also 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 turning over the electrical box 2 on the indoor unit of the air conditioner is as follows: Figures 7 to 9 As shown: the slideways 24 on both sides of the electrical box 2 will cooperate with the T-shaped component, so that the electrical box 2 can be turned around the hinge shaft 6 of the T-shaped component, and the electrical box 2 can be turned 90 degrees clockwise.

[0098] The process of fixing the electrical box 2 on the air conditioner indoor unit is as follows: Figures 9 to 11As shown: after the electrical box 2 is flipped 90 degrees, it is moved to the left. When the electrical box 2 moves to the leftmost state, the electrical box 2 will be restricted by the slide 24 because the upward movement direction of the electrical box 2 will be restricted by the guide component 4 at this time, and the downward movement direction is also restricted because the bottom surface of the electrical box 2 is close to the housing 1 or other components of the air-conditioning indoor unit. In this state, the electrical box 2 is in a state where the staff can perform maintenance.

[0099] The electrical box 2 is fixed intact, and the staff can open the cover of the electrical box 2 at the lower air-conditioning indoor unit for maintenance and debugging, which will greatly reduce the maintenance difficulty of the staff and can greatly improve the maintenance efficiency.

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

[0101] 1. By arranging the slideway 24 and the guide component 4 on the electrical box 2, the electrical box 2 hidden in the indoor unit of the air conditioner can be pulled out, and the electrical box 2 is opened to face the maintenance personnel, so that the maintenance personnel can perform maintenance and debugging conveniently;

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

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

[0104] 4. The structure for realizing movement, flipping and self-fixation of the electrical box 2 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 folded, it can continue to hide the interior of the air conditioner indoor unit, thereby not changing the original appearance.
