Technical Field

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

[0002] In related technologies, the air guide plate of the air conditioner is directly driven by a drive motor to rotate, which results in a limited rotation angle of the air guide plate. This causes the air guide plate to form a large opening with the bottom of the air conditioner when it is open, which affects the aesthetics. At the same time, because the air guide plate has a certain width, it will block the wind and affect the cooling and heating effect of the air conditioner. Utility Model Content

[0043] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] The following is for reference. Figures 1-10 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0045] Reference Figure 1 and Figure 2 According to an embodiment of the present utility model, the air conditioner 100 includes an air conditioner body 10. The length of the air conditioner body 10 extends in the left-right direction, and the height of the air conditioner body 10 extends in the up-down direction. That is, the air conditioner 100 is a wall-mounted air conditioner.

[0046] Specifically, the air conditioner body 10 has an air duct 121 and an air outlet 1012. The air outlet 1012 is located at the lower part of the air conditioner body 10 and is connected to the outlet of the air duct 121.

[0047] Reference Figure 3 and Figure 4 The air conditioner 100 also includes an air guide assembly 20, which is disposed on the air conditioner body 10. The air guide assembly 20 includes a drive motor 21, a transmission mechanism 22, and an air guide plate 23. The drive motor 21 is connected to the air guide plate 23 through the transmission mechanism 22. When the drive motor 21 is working, the drive motor 21 can drive the transmission mechanism 22 to move, and the transmission mechanism 22 can drive the air guide plate 23 to move between a first position and a second position.

[0048] Specifically, such as Figure 3 As shown, when the air guide plate 23 is in the first position, the air guide plate 23 closes the air outlet 1012; as Figure 4 As shown, when the air guide plate 23 is in the second position, the air guide plate 23 opens the air outlet 1012, and the air guide plate 23 is located below the bottom of the air conditioner body 10. In a plane perpendicular to the height direction, the projection of the air guide plate 23 is located behind the projection of the air outlet 1012.

[0049] For example, when the air conditioner 100 is turned off, the air guide plate 23 is in the first position. At this time, the air guide plate 23 covers the air outlet 1012. On the one hand, it can prevent foreign objects from entering the air conditioner body 10 from the air outlet 1012. On the other hand, it can make the appearance of the air conditioner 100 more flat and beautiful. Of course, in the example where the air guide plate 23 is provided with a diffuser hole 231, when the air conditioner 100 is in the windless mode, the air guide plate 23 is in the first position, and most of the airflow in the air duct 121 can be discharged from the diffuser hole 231, making the airflow more gentle and achieving a windless effect.

[0050] When the air conditioner 100 is turned on, the drive motor 21 drives the air guide plate 23 from the first position to the second position through the transmission mechanism 22, thereby opening the air outlet 1012. At this time, the air guide plate 23 is located below the bottom of the air conditioner body 10. When the air conditioner 100 is viewed from below, the air guide plate 23 does not exceed the air outlet 1012, and the air guide plate 23 does not block the wind at the air outlet 1012.

[0051] According to the air conditioner 100 of this utility model embodiment, the drive motor 21 can drive the air guide plate 23 to move between a first position and a second position through the transmission mechanism 22. When the air guide plate 23 is in the second position, it can be located below the bottom of the air conditioner body 10. Compared with the related technology where the drive motor 21 directly drives the air guide plate 23, on the one hand, the opening size between the air guide plate 23 and the air conditioner body 10 can be reduced, which is beneficial to improving the appearance of the air conditioner 100. On the other hand, since the air guide plate 23 is located at the bottom of the air conditioner body 10 and the air outlet when it is in the second position, it is more aesthetically pleasing. The air guide plate 23 is located behind the air outlet 1012, so it does not obstruct the airflow at the air outlet 1012. Especially when the air conditioner 100 is heating, the hot air blown out from the air outlet 1012 will rise due to its physical properties, while the user needs the hot air to sink as much as possible. If the air guide plate 23 forms an obstruction at the air outlet 1012, it will aggravate the rising of the hot air. However, the air guide plate 23 of the air conditioner 100 in this embodiment of the utility model does not form an obstruction at the air outlet 1012, thus reducing the rising of the hot air and making the cooling and heating effect of the air conditioner 100 more excellent.

[0052] According to some embodiments of this utility model, refer to Figure 4When the air guide plate 23 is in the second position, in a plane perpendicular to the left and right direction, the projected front end of the air guide plate 23 is close to the bottom of the air conditioner body 10 and not lower than the rear side of the projected air outlet 1012. That is, the front end of the air guide plate 23 is higher than the rear end of the air guide plate 23, or the front end and the rear end of the air guide plate 23 are set at the same height.

[0053] In the above technical solution, by limiting the air guide plate 23 to the second position, the front end of the air guide plate 23 is close to the bottom of the air conditioner body 10 and not lower than the rear end. On the one hand, the front end of the air guide plate 23 can block the rear end of the air guide plate 23. In this way, when the air conditioner 100 is viewed from the front, only the outer side of the air guide plate 23 can be seen, and the inner side of the air guide plate 23 will not be exposed, making the air conditioner 100 more aesthetically pleasing. On the other hand, it can reduce the opening between the front end of the air guide plate 23 and the bottom of the air conditioner body 10, which not only makes the air conditioner 100 more aesthetically pleasing, but also reduces the problem of air leakage from the air outlet 1012 through the gap between the front end of the air guide plate 23 and the bottom of the air conditioner body 10, thus making the cooling and heating effects of the air conditioner 100 better to a certain extent.

[0054] In some embodiments, refer to Figure 4 The air outlet 1012 is located on the lower front side and the bottom front side of the air conditioner body 10. In a plane perpendicular to the left and right directions, the projected shape of the air guide plate 23 is arc-shaped.

[0055] In the above technical solution, by limiting the projection shape of the air guide plate 23 in the plane perpendicular to the left and right directions to an arc shape, the air guide plate 23 can better avoid the air conditioner body 10 during the movement between the first position and the second position, thereby improving the operational reliability of the air conditioner 100.

[0056] In some embodiments, in the second position, the distance between the front and rear ends of the air guide plate 23 projected in a plane perpendicular to the left and right directions and the bottom of the air conditioner body 10 is less than or equal to 5 mm.

[0057] For example, the distance between the front end of the air guide plate 23 projected in a plane perpendicular to the left and right direction and the bottom of the air conditioner body 10 is L1, which can be 1mm, 3mm, 5mm, etc. The distance between the rear end of the air guide plate 23 projected in a plane perpendicular to the left and right direction and the bottom of the air conditioner body 10 is L2, which can be 1mm, 3mm, 5mm, etc.

[0058] Therefore, by limiting the distance between the front and rear ends of the air guide plate 23 projected in a plane perpendicular to the left and right directions and the bottom of the air conditioner body 10 to meet the above range, the problem of air leakage from the air outlet 1012 through the gap between the front end of the air guide plate 23 and the bottom of the air conditioner body 10 is reduced when the air conditioner 100 is running, thereby improving the cooling and heating effect of the air conditioner 100.

[0059] In some embodiments, refer to Figures 5-9 The transmission mechanism 22 of the air conditioner 100 includes a rack and pinion mechanism. That is, the drive motor 21 drives the air guide plate 23 to move between a first position and a second position through the rack and pinion mechanism.

[0060] In related technologies, the drive motor 21 is used to directly drive the air guide plate 23. This requires the drive motor 21 to be fixed close to the air guide plate 23. On the one hand, this limits the opening angle of the air guide plate 23. On the other hand, it requires a fixed assembly method during installation, resulting in low integration and affecting assembly efficiency.

[0061] Compared with the aforementioned related technologies, in the embodiments of this application, a gear and rack mechanism is used to drive the drive motor 21 and the air guide plate 23. By selecting a suitable gear and rack mechanism, on the one hand, the drive motor 21 does not need to be set close to the air guide plate 23, so the drive motor 21 is more flexible in spatial layout and can also achieve large-angle rotation of the air guide plate 23. On the other hand, the drive motor 21 and the gear and rack mechanism can be modularly designed, which is convenient for installation and improves assembly efficiency to a certain extent.

[0062] In some specific embodiments, reference is made to Figures 3-5 , Figure 8 The transmission mechanism 22 of the air conditioner 100 includes a gear 221 and a rack 222 that mesh with each other. The drive motor 21 is connected to the gear 221, and the air guide plate 23 is connected to the rack 222.

[0063] Among them, rack 222 is an arc-shaped rack, and the center of the circle containing the arc-shaped rack and gear 221 are located on the same side of the arc-shaped rack.

[0064] In the embodiments of this application, by setting the rack 222 as an arc rack and setting the center of the circle containing the arc rack and the gear 221 on the same side of the arc rack, the rotation axis of the air guide plate 23 is located above the air guide plate 23. On the one hand, during the rotation of the air guide plate 23 between the first position and the second position, the outer side of the air guide plate 23 always serves as the appearance surface of the air conditioner 100, avoiding the exposure of the inner side of the air guide plate 23 as much as possible, making the air conditioner 100 more aesthetically pleasing during operation. On the other hand, the gear 221 and the rack 222 are arranged more compactly, reducing the space occupied by the transmission mechanism 22 during the movement.

[0065] In some embodiments, refer to Figure 3 and Figure 4 The air guide plate 23 of the air conditioner 100 rotates between a first position and a second position around a rotation axis that extends in the left-right direction. The center of the circle containing the arc-shaped rack is located on the rotation axis. This arrangement allows the air guide plate 23 and the arc-shaped rack to rotate around the same rotation axis during the movement of the air guide assembly 20, ensuring that the movement trajectory of the air guide plate 23 meets the design requirements.

[0066] In some specific embodiments, reference is made to Figures 2-4 The air conditioner body 10 includes a housing 11, an air duct component 12, a fan wheel 13, and a heat exchanger 14. The housing 11 is provided with an air inlet 1011 and an air outlet 1012. The air duct component 12 is located inside the housing 11 and defines an air outlet duct 121. The fan wheel 13 is located at the inlet of the air duct 121. In the direction of air flow, the heat exchanger 14 is located between the air inlet 1011 and the fan wheel 13.

[0067] When the air conditioner 100 is running, the fan wheel 13 rotates, which allows air outside the casing 11 to enter the casing 11 through the air inlet 1011. As the air flows through the heat exchanger 14, it can exchange heat with the heat exchanger 14 and finally be discharged from the air outlet 1012, thereby enabling the air conditioner 100 to achieve the effect of cooling or heating.

[0068] In this configuration, the centers of the circles containing the impeller 13 and the arc-shaped rack are located on the same side of the arc-shaped rack. This arrangement allows the impeller 13 and the arc-shaped rack to be more compactly arranged during the movement of the transmission mechanism 22, reducing the space occupied by the transmission mechanism 22 during operation.

[0069] In some specific embodiments, reference is made to Figure 3 and Figure 4 and further refer to Figure 5 The air conditioner 100 also includes a connector 24, through which the air guide plate 23 is connected to the rack 222.

[0070] The connector 24 itself or between the connector 24 and the rack 222 has a clearance groove 240 to avoid the lower edge of the air outlet 1012.

[0071] In the above technical solution, by setting the connector 24, while ensuring the connection between the rack 222 and the air guide plate 23, the distance between the rack 222 and the air guide plate 23 can be increased, making the rack 222 more flexible in spatial layout and facilitating the large-angle rotation of the air guide plate 23.

[0072] In addition, by setting the clearance groove 240, the lower edge of the air outlet 1012 can be avoided, preventing the connecting piece 24 from colliding with the lower edge of the air outlet 1012 during the rotation of the air guide plate 23. This allows the air guide plate 23 to rotate at a larger angle and move smoothly to the set second position.

[0073] In some specific embodiments, reference is made to Figure 5 Connector 24 is a sheet metal part.

[0074] It is understandable that during the movement of the air guide plate 23 in the first and second positions, the connecting member 24, as the connecting structure between the air guide plate 23 and the rack 222, needs to pass through the assembly gap on the air conditioner body 10. Since the sheet metal part has high structural strength and can withstand a large load, in this embodiment of the application, by setting the connecting member 24 as a sheet metal part, the size of the connecting member 24 in the left and right directions can be appropriately reduced while ensuring the structural strength of the connecting member 24, so as to reduce the assembly gap and make the appearance of the air conditioner 100 more beautiful and compact.

[0075] In some specific embodiments, reference is made to Figure 5 The connector 24 includes a body part 241, a first connecting part 242, and a second connecting part 243. The two ends of the body part 241 are respectively connected to the first connecting part 242 and the second connecting part 243. The first connecting part 242 is snapped into the air guide plate 23. The second connecting part 243 is connected to the connecting lug 2221 on the rack 222 by a fastener 244.

[0076] For example, the air guide plate 23 has a buckle 231 on the side facing the connector 24, and the first connecting part 242 has a slot 2421. The buckle 231 and the slot 2421 engage with each other, thereby connecting the first connecting part 242 with the air guide plate 23.

[0077] For example, the second connecting part 243 has a connecting hole, the connecting lug 2221 on the rack 222 has a mating hole, and the fastener 244 passes through the connecting hole and the mating hole, so that the second connecting part 243 is connected to the rack 222, thereby connecting the rack 222 to the air guide plate 23 through the connector 24.

[0078] In some examples, the body portion 241, the first connecting portion 242, and the second connecting portion 243 are integrally formed parts; or, as... Figure 5 As shown, one of the first connecting part 242 and the second connecting part 243 is integrally formed with the main body part 241, which helps to reduce the number of parts and eliminate some connection steps, thereby improving the assembly efficiency of the air conditioner 100 and also improving the structural strength of the connector 24.

[0079] In other examples, the main body 241, the first connecting part 242, and the second connecting part 243 are each molded separately. This arrangement allows for flexible design and processing of the structure of each component.

[0080] like Figure 8 As shown, in some examples, the inner side of the air guide plate 23 is provided with a detachable connecting block 232, and the air guide plate 23 is connected to the first connecting part 242 through the connecting block 232. The connecting block 232 and the first connecting part 242 can be connected by fasteners, and the connecting block 232 and the air guide plate 23 can be connected by fasteners or by snap-fit.

[0081] In some alternative embodiments, refer to Figure 5 The transmission mechanism 22 further includes: a first housing 223, the first housing 223 includes a body 2231 and a cover 2232, the body 2231 and the cover 2232 are detachably connected and define a first receiving cavity 223a between them, and the gear 221 and the rack 222 are disposed in the first receiving cavity 223a.

[0082] The first housing 223 has a first opening 223c, and the connector 24 passes through the first opening 223c to connect the air guide plate 23 and the rack 222.

[0083] In other words, the transmission mechanism 22 includes a first housing 223, a gear 221, and a rack 222. The first housing 223 defines a first receiving cavity 223a. The gear 221 and the rack 222 are disposed in the first receiving cavity 223a, so that the first housing 223 encloses the gear 221 and the rack 222. On the one hand, it can protect the gear 221 and the rack 222, making their movement less susceptible to external interference. On the other hand, it can realize the modular design of the transmission mechanism 22, which facilitates the installation, disassembly, and maintenance of the transmission mechanism 22.

[0084] In the embodiments of this application, by providing a first opening 223c on the first housing 223, it is convenient for the connector 24 to connect the air guide plate 23 and the rack 222, and it can also play a role in avoiding collisions, allowing the connector 24 to rotate within a certain angle range, thereby allowing the air guide plate 23 to move between the first position and the second position.

[0085] For example, the housing body 2231 is provided with a latching protrusion 22311, and the housing cover 2232 is provided with a latching hole 22321. The latching protrusion 22311 and the latching hole 22321 are engaged to achieve a detachable connection between the housing body 2231 and the housing cover 2232.

[0086] For example, there can be multiple locking protrusions 22311 and locking holes 22321. Multiple locking protrusions 22311 and multiple locking holes 22321 are engaged in a one-to-one manner, thereby improving the connection reliability between the housing 2231 and the cover 2232.

[0087] In some specific embodiments, reference is made to Figure 5 The cavity wall of the first receiving cavity 223a is provided with a first arc-shaped sliding groove 223b, and the rack 222 is movably disposed in the first arc-shaped sliding groove 223b.

[0088] The cavity wall of the first receiving cavity 223a is provided with a first arc-shaped sliding groove 223b, which can both limit and guide the rack 222, so that the rack 222 can slide along the first arc-shaped sliding groove 223b under the drive of the gear 221. This ensures that the air guide plate 23 can rotate between the first position and the second position according to the preset trajectory, preventing the rack 222 from falling off or deviating, which would result in the air guide plate 23 not moving into place and causing the wind to be blocked.

[0089] The air conditioner body 10 includes a face frame 111, a first housing 223 is disposed inside the face frame 111 and near the side wall of the face frame 111, and a drive motor 21 is disposed in the first housing 223 and is located on the side of the first housing 223 away from the side wall of the face frame 111 in the left-right direction.

[0090] During installation, gear 221 and rack 222 can be installed onto housing 2231. Then, drive motor 21 is fixed to the side of housing 2231 away from gear 221, and the motor shaft of drive motor 21 is connected to gear 221. Connecting piece 24 is then connected to rack 222. Finally, housing cover 2232 is fastened onto housing 2231, completing the assembly of transmission mechanism 22, drive motor 21, and connecting piece 24. The combined structure of drive motor 21, transmission mechanism 22, and connecting piece 24 can be directly installed into face frame 111. Finally, connecting piece 24 is connected to air guide plate 23, completing the assembly of air guide assembly 20. Installation is convenient and operation is simple.

[0091] Therefore, in this embodiment, the air guide assembly 20 and the face frame 111 are integrated into one unit to achieve a modular design, which can effectively improve the assembly efficiency of the air conditioner 100.

[0092] It should be noted that, in this embodiment of the application, the air guide assembly 20 may include two drive motors 21, two transmission mechanisms 22 and two connectors 24. The two transmission mechanisms 22 may be installed inside the face frame 111 and are respectively close to the left and right side walls of the face frame 111. The two drive motors 21 are respectively arranged on the side of the two transmission mechanisms 22 that are close to each other in the left and right direction. The racks 22 of the two transmission mechanisms 22 are respectively connected to the inner side of the air guide plate 23 through the two connectors 24, so that the air guide plate 23 can be driven to move simultaneously by the two drive motors 21.

[0093] In some alternative embodiments, refer to Figures 6-9 The air conditioner body 10 includes a face frame 111, which includes a main body 1111 and a side plate 1112. The side plate 1112 is detachably disposed at one end of the main body 1111 in the left-right direction.

[0094] The transmission mechanism 22 also includes a second housing 224, which is located between the side plate 1112 and the main body 1111 and is detachably connected to the main body 1111. A second receiving cavity 224a is defined between the second housing 224 and the main body 1111, and the gear 221 and the rack 222 are disposed in the second receiving cavity 224a.

[0095] The main body 1111 has a second opening 224c between the main body 1111 and the second housing 224, and the connector 24 passes through the second opening 224c to connect the air guide plate 23 and the rack 222.

[0096] In this embodiment of the application, by providing a second opening 224c, it is convenient for the connector 24 to connect the air guide plate 23 and the rack 222, and it can also have an avoidance effect, allowing the connector 24 to rotate within a certain angle range, thereby allowing the air guide plate 23 to move between the first position and the second position.

[0097] For example, the second housing 224 can be connected to the main body 1111 by a snap-fit ​​connection, thereby enclosing the gear 221 and rack 222 between the second housing 224 and the main body 1111.

[0098] In some specific embodiments, reference is made to Figures 6-8 The cavity wall of the second receiving cavity 224a is provided with a second arc-shaped sliding groove 224b, and the rack 222 is movably disposed in the second arc-shaped sliding groove 224b.

[0099] The cavity wall of the second receiving cavity 224a is provided with a second arc-shaped sliding groove 224b, which can both limit and guide the rack 222, so that the rack 222 can slide along the second arc-shaped sliding groove 224b under the drive of the gear 221. This ensures that the air guide plate 23 can rotate between the first position and the second position according to the preset trajectory, preventing the rack 222 from falling off or deviating, which would result in the air guide plate 23 not moving into place and causing the wind to be blocked.

[0100] The drive motor 21 is located in the second housing 224 and is situated between the side of the second housing 224 away from the main body 1111 and the side plate 1112 in the left-right direction.

[0101] During installation, gear 221 and rack 222 can be installed on one side of the main body 1111. Then, the second housing 224 is installed on the main body 1111 to cover gear 221 and rack 222. The drive motor 21 is installed on the second housing 224 with fasteners (e.g., screws) and the fasteners are connected to the main body 1111, thereby fixing the second housing 224 and drive motor 21 to the main body 1111. Finally, the side plate 1112 is covered on the main body 1111, so that gear 221, rack 222 and the second housing 224 are all enclosed between the main body 1111 and the side plate 1112. The installation is convenient and the operation is simple.

[0102] When maintenance is required, simply remove the side plate 112 to expose the drive motor 21 and the second housing 224, making maintenance more convenient.

[0103] In the above technical solution, the drive motor 21 is placed between the second housing 224 and the side plate 1112, which can protect the drive motor 21 and help extend the service life of the drive motor 21. When it is necessary to maintain the drive motor 21, the drive motor 21 can be exposed by simply removing the side plate 1112, making maintenance more convenient.

[0104] Therefore, in this embodiment, the air guide assembly 20 and the face frame 111 are integrated into one unit to achieve a modular design, which can effectively improve the assembly efficiency of the air conditioner 100.

[0105] It should be noted that the air guide assembly 20 may include two drive motors 21, two transmission mechanisms 22 and two connecting parts 24. The two drive motors 21 and the two transmission mechanisms 22 are respectively installed on the left and right ends of the main body 1111 of the face frame 111. The two side plates 1112 of the face frame 111 cover the left and right ends of the main body 1111 respectively. The racks 22 of the two transmission mechanisms 22 are respectively connected to the inner side of the air guide plate 23 through the two connecting parts 24, so that the air guide plate 23 can be driven to move simultaneously by the two drive motors 21.

[0106] like Figure 10 As shown, in some examples, the transmission mechanism 22 has a first buffer portion 2251 and a second buffer portion 2252 arranged on the active path of the connector 24, with the connector 24 located between the first buffer portion 2251 and the second buffer portion 2252.

[0107] Specifically, when the air guide plate 23 is in the first position, the first buffer part 2251 can stop on one side of the connector 24, and when the air guide plate 23 is in the second position, the second buffer part 2252 can stop on the other side of the connector 24.

[0108] In the above technical solution, by setting the first buffer part 2251 and the second buffer part 2252 on the moving path of the connector 24, the connector 24 can be limited, thereby limiting the sliding range of the rack 222. On the other hand, the first buffer part 2251 and the second buffer part 2252 have a buffering effect, which can reduce the sound of the connector 24 colliding, thereby reducing the operating noise of the air conditioner 100.

[0109] In some specific examples, the first buffer part 2251 and the second buffer part 2252 can be a ring structure. For example, the first buffer part 2251 and the second buffer part 2252 can both be rubber sleeves or sponge sleeves. The first buffer part 2251 and the second buffer part 2252 can be sleeved on the fixing post 226 at the corresponding position to realize the positioning and installation of the first buffer part 2251 and the second buffer part 2252.

[0110] like Figure 5 and Figure 10 As shown, in this embodiment, the first buffer part 2251 and the second buffer part 2252 are disposed in the first housing 223 and located on one side of the first arc-shaped groove 223b.

[0111] When the air guide plate 23 is in the first position, the first buffer part 2251 can stop on one side of the connector 24. At this time, there can be a small gap between one end of the rack 222 and one end wall of the first arc-shaped slide groove 223b. When the air guide plate 23 is in the second position, the second buffer part 2251 can stop on the other side of the connector 24. At this time, there can be a small gap between the other end of the rack 222 and the other end wall of the first arc-shaped slide groove 223b. This ensures that the rack 222 will not collide with the two end walls of the first arc-shaped slide groove 223b when it moves to the two extreme positions, further reducing the operating noise of the air conditioner 100.

[0112] like Figure 8 and Figure 9As shown, in this embodiment, the first buffer portion 2251 and the second buffer portion 2252 are disposed on the first main body portion 1111 or the second housing 224 and are located on one side of the second arc-shaped groove 224b.

[0113] When the air guide plate 23 is in the first position, the first buffer part 2251 can stop on one side of the connector 24. At this time, there can be a small gap between one end of the rack 222 and one end wall of the second arc-shaped slide 224b. When the air guide plate 23 is in the second position, the second buffer part 2251 can stop on the other side of the connector 24. At this time, there can be a small gap between the other end of the rack 222 and the other end wall of the second arc-shaped slide 224b. This ensures that the rack 222 will not collide with the two end walls of the second arc-shaped slide 224b when it moves to the two extreme positions, thereby reducing the operating noise of the air conditioner 100.

[0114] According to some embodiments of the present invention, the air guide plate 23 is provided with a plurality of air dispersing holes 23a. When the air guide plate 23 is in the first position and the air conditioner 100 is working, the airflow in the air duct 121 can be discharged from the plurality of air dispersing holes 23a, making the airflow more gentle, achieving a windless effect, and improving the user's comfort.
