Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] Currently, to prevent dust from entering the indoor unit through the air inlet when the air conditioner is not in operation, causing dust accumulation on internal components and potential malfunctions, some air conditioner indoor units will have a rotatable and openable panel at the air inlet. This panel is connected to a drive arm, which can move along its axial direction, causing the panel to rotate around the pivot. Specifically, the panel has a guide rail with a groove, and the end of the drive arm has a sliding part that can be slidably installed in the groove. When the panel is opened, the angle between the drive arm and the panel gradually increases from an initial acute angle to 90°, and exceeds 90° when fully opened. During this process, when the angle is less than 90°, the thrust of the drive arm presses the sliding part tightly against the inner wall of the groove, ensuring smooth transmission; when the angle is greater than 90°, the thrust direction reverses, causing a gap between the sliding part and the groove, which can lead to instability in the panel's movement trajectory. The sliding part collides with the non-working surface of the groove, causing the panel to jam and produce abnormal noises. Utility Model Content

[0003] In view of the above problems, this utility model is proposed to provide an air conditioning indoor unit and air conditioner that overcomes or at least partially solves the above problems.

[0004] One objective of this invention is to solve the problem that the panel of an existing air conditioner indoor unit is prone to jamming during opening.

[0005] Specifically, this utility model provides an indoor unit for an air conditioner, comprising:

[0006] The body has an air inlet formed on it;

[0007] A panel, which is rotatably mounted at the air inlet, is used to open or close the air inlet;

[0008] A guide rail is disposed on the inner wall of the panel, and a sliding part is slidably installed inside the guide rail;

[0009] A drive arm, which is movable along the inside and outside of the machine body;

[0010] A connecting rod, one end of which is fixedly connected to the sliding part, and the other end of which is rotatably connected to the drive arm; the connecting rod is inclined relative to the extension direction of the guide rail.

[0011] Optionally, the sliding part is a cuboid slider, and the length direction of the slider is parallel to the extension direction of the guide rail.

[0012] Optionally, the guide rail includes a first guide rail portion and a second guide rail portion, the first guide rail portion having a first sliding groove, the second guide rail portion having a second sliding groove, and the openings of the first sliding groove and the second sliding groove being arranged opposite to each other;

[0013] The two ends of the sliding part are respectively installed in the first sliding groove and the second sliding groove.

[0014] Optionally, the first guide rail and the second guide rail can be detachably connected.

[0015] Optionally, one end of the first guide rail is provided with a first insertion part, the extension direction of the first insertion part being parallel to the extension direction of the first slide groove; the other end of the first guide rail is provided with a second insertion part, the extension direction of the second insertion part being perpendicular to the extension direction of the first slide groove.

[0016] The second guide rail is provided with a first insertion slot and a second insertion slot. The first insertion slot is used to engage with the first insertion part, and the second insertion slot is used to engage with the second insertion part.

[0017] Optionally, one end of the guide rail is rotatably connected to the panel, and the other end of the guide rail is detachably connected to the panel.

[0018] Optionally, there are two drive arms, which are respectively disposed on both sides of the width direction of the air inlet.

[0019] Optionally, the body also has an air outlet, the air inlet and the air outlet are located on the front side of the body, and the air inlet is located above the air outlet;

[0020] The rotation axis of the panel is located at the bottom of the panel.

[0021] Optionally, the indoor unit of the air conditioner further includes:

[0022] The panel is rotatably mounted at the air inlet via at least two rotating arms; one end of each rotating arm is connected to the panel, and the other end is provided with a rotating shaft.

[0023] On the other hand, this utility model also provides an air conditioner, including an outdoor unit and an indoor unit as described in any of the above.

[0024] In this invention, an indoor air conditioning unit and air conditioner incorporate a connecting rod between the sliding part and the drive arm. This connecting rod is angled and not perpendicular to the guide rail. By adding this angled connecting rod, the force transmission path between the drive arm and the sliding part is restructured. As the drive arm moves axially, the lever action of the connecting rod continuously applies a normal component force pointing towards the inner wall of the guide rail to the sliding part, ensuring that the sliding part remains firmly against the working surface of the slide groove. This effectively eliminates the clearance that occurs when the angle between the drive arm and the panel exceeds 90 degrees in existing technologies. Therefore, this invention solves the problem of panel jamming and abnormal noise during opening, ensuring smooth operation.

[0037] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 6 This utility model embodiment provides an air conditioner indoor unit 100, which includes a body 110, a panel 120, a guide rail 130, a drive arm 141, and a connecting rod 180.

[0038] An air inlet 160 is formed on the body 110. A panel 120 is rotatably mounted at the air inlet 160 and is used to open or close the air inlet 160. A guide rail 130 is disposed on the inner wall of the panel 120, and a sliding part 150 is slidably mounted inside the guide rail 130. The guide rail 130 has a groove. A drive arm 141 is movably disposed along the inward and outward directions of the body 110. One end of a connecting rod 180 is fixedly connected to the sliding part 150, and the other end is rotatably connected to the drive arm 141; the connecting rod 180 is inclined relative to the extending direction of the guide rail 130.

[0039] When the air conditioner is turned on, the drive arm 141 moves from the inside to the outside along the body 110, driving the sliding part 150 to slide along the guide rail 130 via the connecting rod 180, thereby driving the panel 120 to rotate around the rotating shaft 1211 to open the air inlet. When the air conditioner is turned off, the drive arm 141 moves in the opposite direction, and the connecting rod 180 drives the sliding part 150 to slide in the opposite direction along the guide rail 130, pulling the panel 120 back to the position where it completely blocks the air inlet 160.

[0040] This embodiment reconstructs the force transmission path between the drive arm 141 and the sliding part 150 by adding an inclined connecting rod 180. When the drive arm 141 moves inward and outward along the body 110, the inclined design of the connecting rod 180 decomposes the driving force into two components: tangential component: the sliding part 150 pushes the panel 120 to rotate around the axis along the guide rail direction, realizing the opening and closing of the air inlet; normal component: the lever effect of the connecting rod continuously presses the sliding part 150 against the inner wall of the slide groove. Even if the angle between the drive arm and the panel exceeds 90°, the connecting rod 180 still maintains the direction of the normal pressing force through its inclined angle, forming an adaptive compensation mechanism. This mechanism forcibly eliminates the fit gap between the sliding part and the slide groove, avoiding the motion instability and panel jamming problems of traditional structures at critical angles. In addition, the reduction of frictional resistance further improves the transmission efficiency and the smoothness of panel movement.

[0041] like Figures 2 to 4As shown, in some optional embodiments of this utility model, the angle between the extending direction of the connecting rod 180 and the extending direction of the guide rail 130 is not equal to 90 degrees. For example, when the air inlet is provided on the front shell 111 of the body, the rear end of the connecting rod 180 is hinged to the front end of the drive arm 141, and the front end of the connecting rod 180 is fixedly connected to the sliding part 150. The front end of the connecting rod 180 is close to the upper edge of the panel 120, and the rear end of the connecting rod 180 is away from the upper edge of the panel 120. The rotation axis of the panel is located at the bottom of the panel. Further, the slider part is located in front of the connecting rod 180.

[0042] like Figure 5 As shown, in some optional embodiments of this utility model, the sliding part 150 is a cuboid slider, and the length direction of the slider is parallel to the extension direction of the guide rail 130. This arrangement increases the contact area between the slider and the groove of the guide rail 130, thereby facilitating the stable rotation of the panel 120. In alternative embodiments, the sliding part 150 can also have other shapes.

[0043] In some optional embodiments of this utility model, the guide rail 130 includes a first guide rail portion 131, the first guide rail portion 131 having a first sliding groove, and a sliding portion 150 installed in the first sliding groove. The sliding portion 150 is a pulley or a slider.

[0044] like Figure 6 As shown, in some optional embodiments of this utility model, each guide rail 130 includes a first guide rail portion 131 and a second guide rail portion 132. The first guide rail portion 131 has a first sliding groove. The second guide rail portion 132 has a second sliding groove, and the openings of the first and second sliding grooves are arranged opposite to each other. The two ends of the sliding portion 150 are respectively installed in the first and second sliding grooves.

[0045] Specifically, each sliding part 150 includes a first sliding part installed in a first sliding groove and a second sliding part installed in a second sliding groove. The first sliding part and the second sliding part can be either a slider or a pulley. When both the first sliding part and the second sliding part are slider structures, they can be fixedly connected or integrally set, and together they can form a cuboid slider structure. When the first sliding part and the second sliding part are pulleys, a mounting shaft is fixedly provided at the end of the connecting rod 180, and the two pulleys are respectively located at both ends of the axial direction of the mounting shaft.

[0046] Compared to the previous embodiment, this embodiment adds a second guide rail 132 and its corresponding second sliding groove, allowing the first sliding part and the second sliding part to slide within the first sliding groove and the second sliding groove, respectively. This dual guide rail 130 design not only further enhances the stability of the opening and closing action of the panel 120, but also improves the load-bearing capacity and durability of the entire drive system by distributing the force on the sliding part 150, reducing the risk of system failure due to wear or malfunction of a single guide rail 130, thereby improving the overall performance and reliability of the air conditioner indoor unit 100.

[0047] like Figure 6 As shown, in some optional embodiments of this utility model, the first guide rail portion 131 and the second guide rail portion 132 are detachably connected.

[0048] This embodiment employs a detachable connection design for the first guide rail section 131 and the second guide rail section 132, significantly improving the convenience of processing, assembly, and maintenance. Specifically, the split guide rail 130 structure is simpler to process than the one-piece structure; at the same time, the easy disassembly and reassembly of the guide rail 130 greatly facilitates daily cleaning and maintenance as well as repair and replacement work in case of failure, effectively reducing maintenance costs.

[0049] In some optional embodiments of this utility model, the first guide rail portion 131 and the second guide rail portion 132 are fastened by a threaded connection.

[0050] like Figure 6 As shown, in some optional embodiments of this utility model, one end of the first guide rail portion 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 slide groove; the other end of the first guide rail portion 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 slide groove. The second guide rail portion 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.

[0051] This embodiment achieves a stable and flexible plug-in connection between the first guide rail section 131 and the second guide rail section 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 section 131, and a corresponding insertion slot on the second guide rail section 132. This structure not only enhances the stability and reliability of the guide rail 130 connection but also facilitates quick installation and disassembly, improving assembly efficiency and maintenance convenience.

[0052] like Figure 4As shown, in some optional embodiments of this utility model, one end of the guide rail 130 is rotatably connected to the panel 120, and the other end of the 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 guide rail 130 is rotatably mounted on the mounting base 123 via a rotating shaft, the axis of which is perpendicular to the extending direction of the guide rail 130. The guide rail 130 and the panel 120 can be detachably connected by a snap-fit ​​connection or a threaded connection. Preferably, the guide rail 130 and the panel 120 are connected by a snap-fit ​​122. More preferably, multiple snap-fit ​​structures are provided between the guide rail 130 and the panel 120, so that the installation stability of the guide rail 130 can be ensured when the guide rail 130 and the panel 120 are fixed together.

[0053] In this embodiment, when the guide rail 130 is fixed to the panel 120, the panel 120 can only open to a preset angle, such as 35 degrees. Figure 5 As shown, after separating the 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, thus facilitating the cleaning of the filter.

[0054] In some optional embodiments of this utility model, there are at least two drive arms 141, and each drive arm 141 is arranged at intervals.

[0055] like Figure 3 and Figure 4 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.

[0056] 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.

[0057] In some alternative embodiments of this invention, each drive arm 141 is inclined relative to the plane where the air inlet is located.

[0058] 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.

[0059] like Figure 5As 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 drive motor 143 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 141 ensures the stability and reliability of the drive arm 141's movement.

[0060] 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.

[0061] like Figure 3 and Figure 4 As shown, in some optional embodiments of this utility model, the indoor unit of the air conditioner further includes at least two rotating arms 121. The panel 120 is rotatably mounted at the air inlet via the at least two rotating arms. One end of the rotating arm 121 is fixedly connected to or integrally mounted with the panel 120, and the other end is rotatably mounted on the body 110 via a rotating shaft 1211. The body 110 has clearance holes for the rotating arms 121 to pass through, so that the two ends of the rotating arms 121 are located on the inner and outer sides of the body 110, respectively. In this embodiment, by providing two rotating arms, it is more conducive to the smooth movement of the panel 120.

[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 rotation axis of the panel 120 is disposed at the bottom of the panel 120. The drive arm 141 is inclined upward relative to the front shell 111 from front to back. Specifically, the panel 120 is rotatably mounted on the body 110 via the rotating arm 121, which is disposed at the bottom of the panel 120. The body 110 includes a front shell 111, on which an air inlet 160 and an air outlet 170 are formed. 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 indoor unit 100 is a recessed air conditioning indoor unit, a wall-mounted air conditioning indoor unit, a floor-standing air conditioning indoor unit, or other air conditioning indoor units.

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

[0066] An embodiment of this utility model also provides an air conditioner, which includes an outdoor unit and an indoor unit 100 as described in any of the above embodiments.

[0067] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
