[0038] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit 100 according to an embodiment of the present utility model, as shown below. Figure 1 As shown, and refer to Figures 2 to 7 This utility model provides an indoor air conditioning unit 100, including a body 110, a panel 120, a magnetic guide rail 130, and a drive arm 141. An air inlet 160 is formed on the body 110. The panel 120 is rotatably disposed at the air inlet 160. The magnetic guide rail 130 is disposed on the inner sidewall of the panel 120. The drive arm 141 is movable along the inward and outward directions of the body 110. A magnetic roller 150 is disposed at the end of the drive arm 141. The drive arm 141 is configured to drive the magnetic roller 150 to roll along the magnetic guide rail 130, thereby opening and closing the air inlet 160 of the panel 120. During the rolling process, the magnetic roller 150 is configured to adhere to one sidewall of the magnetic guide rail 130.

[0039] The working process of this embodiment is as follows: When the air conditioner is turned on, the drive arm 141 moves from the inside to the outside along the body, driving the magnetic roller 150 at its end to roll along the magnetic guide rail 130 on the inner side of the panel 120. Under the action of magnetic attraction, the magnetic roller 150 is always in close contact with the single side wall of the guide rail, driving the panel 120 to rotate around the pivot, so that the panel 120 smoothly unfolds from the closed state to the preset opening angle to open the air inlet 160. When the air conditioner is turned off, the drive arm 141 moves in the opposite direction, the magnetic roller 150 rolls back along the guide rail, pulling the panel 120 back to the position of completely blocking the air inlet 160. Under the action of magnetic attraction, the rolling contact surface is continuously maintained without gap. Even if a gap occurs between the contact surface of the roller and the guide rail due to external vibration or other reasons during the opening and closing of the air inlet 160 of the panel 120, the magnetic attraction can quickly bring the roller and the guide rail back into contact, eliminating the gap.

[0040] The beneficial effects of this embodiment are as follows: On the one hand, by setting the magnetic guide rail 130 and magnetic roller 150 with magnetic attraction, the anti-disturbance capability of the roller and guide rail is enhanced. When it is necessary to open or close the air inlet 160, the drive arm 141 moves in the inward and outward directions of the body 110, and the drive arm 141 drives the magnetic roller 150 to roll along the magnetic guide rail 130. The side wall of the magnetic roller 150 and the magnetic guide rail 130 are tightly fitted, that is, the contact surface of the magnetic roller 150 and the magnetic guide rail 130 always maintains a stable pressing state. This ensures that the opening and closing process of the panel 120 is smooth and without jamming, effectively solving the problem of panel 120 jamming caused by the fit gap between the slide and the sliding part in the prior art.

[0041] On the other hand, compared with existing technologies, rolling friction replaces sliding friction, reducing the wear rate of rollers and guide rails and improving the smoothness and stability of the overall movement.

[0042] Therefore, this embodiment can effectively prevent the panel 120 from jamming during opening or closing by combining rolling friction and magnetic attraction. This prevents the drive motor 143 from being overloaded due to jamming, extends the service life of the drive motor 143, reduces the failure rate, and achieves more reliable and lower noise control of the panel 120.

[0043] In some optional embodiments of this utility model, the magnetic guide rail 130 includes a first guide rail 131, the first guide rail 131 has a first groove, and the magnetic roller 150 is rotatably mounted in the first groove.

[0044] like Figures 5 to 7 As shown, in some optional embodiments of this utility model, the magnetic guide rail 130 includes a first guide rail 131 and a second guide rail 132. The first guide rail 131 has a first groove. The second guide rail 132 has a second groove, and the openings of the first groove and the second groove are arranged opposite to each other. A mounting shaft 151 is fixedly provided at the end of the drive arm 141, and a magnetic roller 150 is provided at each end of the mounting shaft 151; the two magnetic rollers 150 are respectively installed in the first groove and the second groove.

[0045] Compared to the previous embodiment, this embodiment adds a second guide rail 132 and its corresponding second slide groove, allowing the two magnetic rollers 150 connected to the end of the drive arm 141 via the mounting shaft 151 to roll within the first and second slide grooves respectively. This dual-guide rail design not only further enhances the stability of the panel 120's opening and closing action but also improves the load-bearing capacity and durability of the entire drive system by distributing the force on the rollers, reducing the risk of system failure due to wear or malfunction of a single guide rail, thereby improving the overall performance and reliability of the air conditioner indoor unit 100.

[0046] like Figure 5 and Figure 6 As shown, in some optional embodiments of this utility model, the first guide rail 131 and the second guide rail 132 are detachably connected.

[0047] This embodiment employs a detachable connection design for the first guide rail 131 and the second guide rail 132, significantly improving the convenience of processing, assembly, and maintenance. Specifically, the split guide rail structure is simpler to process than the integrated type; at the same time, the easy disassembly and reassembly of the guide rail greatly facilitates daily cleaning and maintenance as well as repair and replacement work in case of failure, effectively reducing maintenance costs.

[0048] like Figure 6As shown, in some optional embodiments of this utility model, one end of the first guide rail 131 is provided with a first insertion portion 1312, the extension direction of the first insertion portion 1312 being parallel to the extension direction of the first sliding groove; the other end of the first guide rail 131 is provided with a second insertion portion 1311, the extension direction of the second insertion portion 1311 being perpendicular to the extension direction of the first sliding groove. The second guide rail 132 is provided with a first insertion groove 1322 and a second insertion groove 1321, the first insertion groove 1322 being used for insertion and engagement with the first insertion portion 1312, and the second insertion groove 1321 being used for insertion and engagement with the second insertion portion 1311.

[0049] In some optional embodiments of this utility model, the first guide rail 131 and the second guide rail 132 are fastened by a threaded connection. Specifically, threaded holes are provided at both ends of the first guide rail 131 and the second guide rail 132, and bolts or screws are screwed into these threaded holes to achieve a stable connection between the two. This connection method is firm and reliable, but requires tools for disassembly and installation.

[0050] This embodiment achieves a stable and flexible plug-in connection between the first guide rail 131 and the second guide rail 132 by providing a first plug-in portion 1312 parallel to the slide groove and a second plug-in portion 1311 perpendicular to the slide groove on the first guide rail 131, and a corresponding insertion slot on the second guide rail 132. This structure not only enhances the stability and reliability of the guide rail connection but also facilitates quick installation and disassembly, improving assembly efficiency and maintenance convenience.

[0051] like Figure 3 and Figure 4 As shown, in some optional embodiments of this utility model, one end of the magnetic guide rail 130 is rotatably connected to the panel 120, and the other end of the magnetic guide rail 130 is detachably connected to the panel 120. Specifically, a mounting base 123 is provided on the inner wall surface of the panel 120, and one end of the magnetic guide rail 130 is rotatably mounted on the mounting base 123 via a rotating shaft, the axis of which is perpendicular to the extension direction of the guide rail. The magnetic guide rail 130 and the panel 120 can be detachably connected by a snap-fit ​​connection or a threaded connection. Preferably, the magnetic guide rail 130 and the panel 120 are connected by a snap-fit ​​122. More preferably, multiple snap-fit ​​structures are provided between the magnetic guide rail 130 and the panel 120, so that the installation stability of the magnetic guide rail 130 can be ensured when the magnetic guide rail 130 and the panel 120 are fixed together.

[0052] In an embodiment, such as Figure 3 As shown, when the magnetic guide rail 130 is fixed to the panel 120, the panel 120 can only open to a preset angle, such as 35 degrees. Figure 4As shown, after separating the magnetic guide rail 130 from the panel 120, the panel 120 can be opened 90 degrees, which is more conducive to air intake at the air inlet 160 and also makes it easier to remove the filter at the air inlet 160 for easy cleaning.

[0053] In some optional embodiments of this utility model, the drive arm 141 is connected to a gear and rack mechanism, which is used to drive the drive arm 141 to move relative to the body 110 in the inward and outward directions.

[0054] Specifically, when the air inlet 160 is located on the front side of the housing 110, the drive arm 141 can move along the front-back direction of the housing. When the air inlet 160 is located on the upper side of the housing 110, the drive arm 141 can move along the vertical direction of the housing.

[0055] like Figures 3 to 6 As shown, the gear and rack mechanism includes a gear 142, a rack, and a drive motor 143. A transmission box 144 is provided inside the machine body 110, and the drive motor 143 and gear 142 are installed inside the transmission box 144. The rack is mounted on the drive arm 141, and the gear 142 meshes with the rack. The output end of the drive motor 143 is connected to the gear 142. The motor is configured to drive the gear 142 to rotate, thereby driving the drive arm 141 to move in the inward and outward directions of the machine body 110. In other words, the drive arm 141, gear 142, rack, and drive motor 143 constitute the drive mechanism of the panel 120. In this embodiment, the gear and rack mechanism has the advantages of high transmission accuracy, long service life, and stable and reliable operation. Using a gear and rack mechanism to drive the drive arm ensures the stability and reliability of the drive arm 141's movement.

[0056] In some alternative embodiments of this utility model, the drive arm 141 is connected to the piston rod of the cylinder, and the drive arm 141 is driven to make linear motion by the cylinder.

[0057] like Figure 2 and Figure 3 As shown, in some optional embodiments of this utility model, there are two drive arms 141, which are respectively disposed on both sides of the width direction of the air inlet 160.

[0058] In other words, the panel 120 is equipped with two drive mechanisms, which are respectively located on both sides of the air inlet 160 in the width direction. Compared with the embodiment with only one drive arm 141, this embodiment can further improve the stability of the panel 120 operation by setting two drive arms 141.

[0059] like Figure 2 and Figure 4As shown, in some optional embodiments of this utility model, the panel 120 is rotatably mounted on the body 110 via a rotating arm 121. Specifically, one end of the rotating arm 121 is connected to the panel 120, and the other end is rotatably mounted on the body 110 via a rotating shaft. The body 110 has a first clearance hole for the rotating arm 121 to pass through, so that the two ends of the rotating arm 121 are located on the inner and outer sides of the body 110, respectively.

[0060] like Figure 3 As shown, in some optional embodiments of this utility model, the rotation axis of the panel 120 is parallel to the lateral direction of the body 110. That is, the rotation shaft on the rotating arm 121 is arranged along the lateral direction of the body 110. This embodiment is particularly suitable for situations where the air conditioner indoor unit 100 is a wall-mounted indoor unit or a horizontally recessed indoor unit.

[0061] In some embodiments of this utility model, the rotation axis of the panel 120 is parallel to the vertical direction of the body 110. That is, the rotation shaft on the rotating arm 121 is arranged along the vertical direction of the body.

[0062] like Figure 2 and Figure 3 As shown, in some optional embodiments of this utility model, an air outlet 170 is also formed on the body 110, and the air inlet 160 and the air outlet 170 are disposed on the front side of the body 110, with the air inlet 160 located above the air outlet 170. The panel 120 is rotatably mounted on the body 110 via a rotating arm 121, which is disposed at the bottom of the panel 120. Specifically, the body 110 includes a front shell, on which an air inlet 160 and an air outlet 170 are formed, and a heat exchange air duct is formed inside the body 110, connecting the air inlet 160 and the air outlet 170; the air inlet 160 and the air outlet 170 are distributed in the vertical direction.

[0063] In this embodiment, both the air inlet 160 and the air outlet 170 are located on the front side of the unit, which facilitates the embedded installation of the indoor unit in a cabinet or wall to meet the diverse usage needs of users. Furthermore, the rotating arm 121 is located at the lower edge of the panel 120, which can prevent the intake airflow and the blower airflow from interfering with each other.

[0064] In some embodiments of this utility model, the air conditioner indoor unit 100 is a recessed air conditioner indoor unit, a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, or other types of air conditioner indoor units.

[0065] Preferably, the indoor unit 100 is a recessed indoor unit.
