The term "and / or" as used herein refers to at least one of the items defined by the term; for example, "A and / or B" can be implemented as "A," or as "B," or as "A and B."

[0069] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0070] This application provides an indoor unit to solve the technical problem that the traditional air conditioner grille has a single function, which limits the application scenarios of the indoor unit.

[0071] Reference Figures 1-14 The indoor unit of this application embodiment includes a housing assembly 10, a sliding door 20, and a grille 30.

[0072] The housing assembly 10 has an air duct 12 and an air outlet 11. The air duct 12 has an air outlet 121 located behind the air outlet 11. Sliding doors 20 are slidable relative to the housing assembly 10 and are configured to at least partially close the air outlet 11. A grille 30 is located between the two sliding doors 20.

[0073] In this embodiment, an inclined air guide channel 331 is provided on the grille 30. The inclined air guide channel 331, which intersects the first plane at an inclination, can change the airflow direction at the air outlet 11. The inclined air guide channel 331 can guide the airflow to be delivered at an inclination. Along the air delivery direction, when the inclined air guide channel 331 is inclined from the center near the air outlet 11 towards the side of the air outlet 11, the grille 30 can achieve a side-expanding airflow effect to achieve the function of rapid temperature control in a large space. When the inclined air guide channel 331 is inclined from the side of the air outlet 11 towards the center, it can gather the side airflow towards the front of the grille 30 through the inclined air guide channel 331, and the grille 30 can achieve a central air-gathering effect, thereby achieving the effect of localized precise air delivery. This can enhance the air-expanding or air-gathering function of the indoor unit, enabling the indoor unit of this embodiment to adapt to various usage scenarios and meet the usage needs of multiple scenarios.

[0074] Optionally, refer to Figure 4 In one embodiment, the grille 30 further includes a straight-through air guide channel 332. The grille 30 includes a first region A1 and a second region A2 located on one side of the first region A1, the straight-through air guide channel 332 is disposed in the first region A1, and the inclined air guide channel 331 is disposed in the second region A2.

[0075] In this embodiment, the straight-through air guide channel 332, which is perpendicular to the first plane, can hardly change the direction of the airflow from the air outlet 11, and has the least resistance to the airflow blown out from the air outlet 11, thereby enabling the airflow to move forward a longer distance and achieving long-distance precise air delivery.

[0076] In this embodiment, both an inclined air guide channel 331 and a straight air guide channel 332 are simultaneously provided on the same grille 30. By rationally arranging the arrangement and relative position of the inclined air guide channel 331 and the straight air guide channel 332, it can achieve both the long-distance air delivery function of the straight air guide channel 332 and the expanded airflow or concentrated airflow function of the inclined air guide channel 331. Moreover, the air delivery effects of the inclined air guide channel 331 and the straight air guide channel 332 can be superimposed, which can meet the needs of scenarios requiring local long-distance air delivery and large-area uniform air expansion, and achieve rapid temperature control in a large space. This can effectively improve the air delivery coverage and temperature uniformity of the space. Alternatively, it can meet the needs of scenarios requiring ultra-long-distance air delivery, improve the problem of excessively rapid wind speed attenuation during concentrated air delivery, and enable the indoor unit of this embodiment to adapt to diverse usage scenarios.

[0077] It should be noted that the plane where the air outlet 11 is located in the embodiments of this application refers to the plane parallel to the vertical direction at the air outlet 11, that is, the vertical plane.

[0078] In the embodiments of this application, reference is made to Figure 4 The grille 30 is divided into two areas. One area has a straight air guide channel 332, and the other area has an inclined air guide channel 331. This allows for the design of the shape of the grille 30 according to the air supply scenario, and adjustment of the air supply range and air supply effect of the indoor unit.

[0079] Optionally, refer to Figure 4 and Figure 8 The housing assembly 10 contains a cross-flow fan 70, causing the air duct 12 to be offset towards one side of the grille 30. The straight air guide channel 332 is located on the side away from the offset direction of the air duct 12, and the inclined air guide channel 331 is located on the side closer to the offset direction of the air duct 12. Thus, the inclined direction of the inclined air guide channel 331 can be set according to different air supply requirements.

[0080] For example, in one alternative implementation, continue to refer to Figure 4 and Figure 8 The inclined direction of the inclined air guide channel 331 is opposite to the offset direction of the air duct 12. As a result, part of the airflow that is biased to one side of the grille 30 can be guided towards the center of the grille 30, making the airflow blown from both sides of the grille 30 more uniform.

[0081] For example, in another alternative implementation, refer to... Figure 4 and Figure 8 The inclined direction of the inclined air guide channel 331 is the same as the offset direction of the air duct 12. As a result, the wind resistance generated by the inclined air guide channel 331 on the airflow can be reduced, thereby extending the air delivery distance.

[0082] It should be noted that the direction of the inclined air guide channel 331 being the same as the offset direction of the air duct 12 means that the direction of the inclined air guide channel 331 and the offset direction of the air duct 12 are located on the same side of the vertical plane along the front-back direction. The direction of the inclined air guide channel 331 being opposite to the offset direction means that the direction of the inclined air guide channel 331 and the offset direction of the air duct 12 are located on opposite sides of the vertical plane along the front-back direction. The specific tilt angle is not limited in this application.

[0083] Alternatively, in another embodiment, refer to Figure 5 The grille 30 includes a first region A1 and a second region A2 located on one side of the first region A1. A first inclined air guide channel 3311 is provided in the first region A1, and a second inclined air guide channel 3312 is provided in the second region A2. In this embodiment, the grille 30 only has an inclined air guide channel 331. By setting the inclination direction of the first inclined air guide channel 3311 and the second inclined air guide channel 3312 respectively, different air supply needs can be met, and the air supply scenarios of the indoor unit can be diversified.

[0084] For example, refer to Figure 5 The ends of the first inclined air guide channel 3311 and the second inclined air guide channel 3312 that are away from the air duct 12 point to the two sides of the air outlet 11, respectively. Thus, the first inclined air guide channel 3311 and the second inclined air guide channel 3312 form an outward V-shape, which can guide the airflow blown out of the air duct 12 to diffuse to both sides, expand the diffusion range of the airflow, and improve the uniformity of the mixing of cold and hot air.

[0085] For example, the ends of the first inclined air guide channel 3311 and the second inclined air guide channel 3312 furthest from the air duct 12 both point towards the center of the air outlet 11. Thus, the first inclined air guide channel 3311 and the second inclined air guide channel 3312 form an inward V-shape, which can guide the airflow blown out of the air duct 12 to converge towards the center of the grille 30 and blow it forward to achieve a wind-gathering effect, which can extend the air delivery distance and achieve precise air delivery over long distances.

[0086] Optionally, the straight air guide channel 332 and the inclined air guide channel 331 can also be arranged alternately in the left-right direction. Alternatively, as shown in the figure... Figures 4-5 The ribs 312 of the grille 30 are arranged in alternating lengths within the horizontal projection. The multiple ribs 312 have different lengths along the front-to-back direction and are arranged alternately along the left-to-right direction of the grille 30. This facilitates the cutting and dispersion of airflow at the air outlet 11, improves the gentle breeze effect of the grille 30, and makes the airflow diffusion more uniform.

[0087] Optionally, refer to Figure 6 In another embodiment, the grille 30 further includes a straight-through air guide channel 332. The grille 30 includes a first region A1 and a second region A2 located on both sides of the first region A1. An inclined air guide channel 331 is disposed in the second region A2, and a straight-through air guide channel 332 is disposed in the first region A1.

[0088] In this embodiment, the inclined air guide channels 331 of the two second regions A2 are located on both sides of the straight air guide channel 332, thereby achieving the effect of long-distance air delivery in the middle and expanding the air delivery range on both sides. Alternatively, it can achieve long-distance air delivery in the middle and air gathering on both sides to enhance the air volume of the air delivery in the middle, achieving the effect of ultra-long-distance air delivery and meeting the needs of different usage scenarios.

[0089] Optionally, refer to Figures 5-6 The inclined air guide channel 331 in the second area A2 is arranged symmetrically to the left and right along the center line of the vertical direction relative to the grille 30.

[0090] In this embodiment, the inclined air guide channel 331 adopts a left-right symmetrical structure layout, which can balance the air supply speed and air feel on both sides of the air conditioner, improve the uniformity of space temperature, avoid the situation of strong wind on one side and weak wind on one side, and thus improve the user experience.

[0091] Of course, the inclined air guide channels 331 constructed in the two second zones A2 can also be tilted to the same side, which can achieve the effect of long-distance precise air delivery and unilateral air expansion, and can further expand the application scenarios of air conditioning.

[0092] Optionally, refer to Figure 6 In one optional embodiment, there are at least two inclined air guide channels 331 in the second region A2, and the inclination angle of each inclined air guide channel 331 in the second region A2 relative to the first plane is the same.

[0093] Alternatively, in another alternative embodiment, the inclined air guide channels 331 within the second region A2 have at least two. From the center of the grille 30 towards both sides of the grille 30, the inclination angle of the at least two inclined air guide channels 331 within the second region A2 relative to the first plane gradually decreases.

[0094] In this embodiment, the inclined air guide channel 331 in the second region A2 adopts a gradual tilt angle design. This gradient tilt angle layout can guide the airflow to gradually diffuse to both sides, effectively widening the air supply coverage range, generating a wind expansion effect in a larger range on both sides, and further improving the temperature uniformity in the space.

[0095] Optionally, refer to Figure 6 The widths of the first region A1 and the second region A2 can be set according to design needs or usage scenarios. In one optional embodiment, the sum of the widths of the two second regions A2 is equal to or approximately equal to the width of the first region A1, thereby achieving a balance in the airflow between the center and the sides and improving the user experience.

[0096] Optionally, refer to Figure 7 The grille 30 also includes at least two third regions A3, which are located on the side of the second region A2 away from the first region A1, and at least one inclined air guide channel 331 is provided in the third region A3.

[0097] The inclined air guide channel 331 in the second region A2 has a first angle with the first plane, and the inclined air guide channel 331 in the third region A3 has a second angle with the first plane, the second angle being greater than the first angle.

[0098] In this embodiment, the grille 30 can also be divided into a third region A3, so that the tilt angle of the inclined air guide channel 331 in the second region A2 and the third region A3 relative to the first plane changes, and the tilt angle of the inclined air guide channel 331 in the third region A3 relative to the first plane is smaller, thereby generating a larger range of air expansion effect.

[0099] Optionally, at least one inclined air guide channel 331 in the third region A3 also has the same inclination angle relative to the first plane.

[0100] Optionally, refer to Figures 4-7 The angle between the inclined air guide channel 331 and the first plane ranges from 60° (inclusive) to 90° (exclusive). This allows for a reduction in airflow resistance in the inclined air guide channel 331 while expanding the airflow diffusion range and improving the uniformity of airflow diffusion.

[0101] Alternatively, in one alternative embodiment, reference is made to... Figures 6-7 The grille 30 includes a frame 311 and multiple ribs 312 disposed on the frame 311. The projection of the frame 311 on the horizontal plane is arc-shaped, and the multiple ribs 312 are perpendicular to the frame 311.

[0102] In this embodiment, the multiple ribs 312 of the grille 30 are perpendicularly arranged to the frame 311, and the grille 30 is configured as an arc-shaped structure with both sides curving towards the first region A1. This allows the frame 311 to utilize its arc-shaped structure to form a straight airflow channel 332 approximately perpendicular to the first plane in the center of the grille 30, and symmetrical inclined airflow channels 331 intersecting the first plane at an angle on both sides of the grille 30. This simplifies the manufacturing cost of the grille 30. The arc-shaped structure of the grille 30 also further enhances its airflow expansion effect. Simultaneously, it further enhances the airflow concentration effect of the grille 30, further extending the air delivery distance of the air conditioner, improving the problem of excessively rapid wind speed attenuation during centralized air delivery, and meeting the needs of ultra-long-distance air delivery. This allows the grille 30 to adapt to different home scenarios.

[0103] In another alternative embodiment, the grille 30 includes a frame 311 and multiple ribs 312 disposed on the frame 311. In the horizontal plane, the ribs 312 are arc-shaped ribs inclined to one side (not shown in the figure), and the spacing between two adjacent arc-shaped ribs forms an inclined air guide channel 331.

[0104] In this embodiment, the grille 30 is a plate-shaped grille. By setting multiple ribs 312 as arc-shaped ribs that are inclined to one side, two adjacent arc-shaped ribs form an inclined air guiding channel 331, thereby achieving the effect of lateral air expansion or central air concentration.

[0105] In another alternative embodiment, the grille 30 includes a frame 311 and multiple ribs 312 disposed on the frame 311. In the horizontal plane, the ribs 312 are bent ribs with the second end inclined to one side (not shown in the figure), and the spacing between two adjacent bent ribs forms a straight air guide channel 332 and an inclined air guide channel 331. The straight air guide channel 332 is closer to the first end, and the inclined air guide channel 331 is closer to the second end.

[0106] In this embodiment, the grille 30 is a plate-shaped grille, and the ribs 312 are configured as partially straight and partially inclined bent ribs. The air guide channel 33 formed by two adjacent bent ribs includes a partially straight air guide channel 332 and a partially inclined air guide channel 331. In the air conditioning supply state, the part of the straight air guide channel 332 is close to the air duct 12, and the part of the inclined air guide channel 331 is far away from the air duct 12. Thus, while reducing wind resistance, the inclined air guide channel 331 can be used to expand the air to one side or concentrate the air towards the center, which can increase the air supply volume per unit time and make the airflow spread quickly and evenly in the space.

[0107] Optionally, refer to Figures 1-2 ,as well as Figures 8-11 There are two sliding doors 20, which are spaced apart in the left and right direction.

[0108] In this embodiment, when the indoor unit is in the air supply state, the sliding door 20 has at least two states: one is the state where all the air outlets 11 on both sides are exposed, and the airflow flows out from the partial air outlets 11 on both sides and the air guide channel 33 of the grille 30, thereby increasing the air supply volume on both sides. The airflow in the middle of the air outlet 11 can pass through the grille 30 to achieve a gentle breeze, which can achieve rapid temperature control in a large space while avoiding direct airflow; and the other is the state where the partial air outlets 11 on both sides are closed, thereby closing the partial air outlets 11 on both sides, which can reduce the air supply volume on both sides, or stop the air supply on both sides, and only the air supply from the air guide channel 33 of the grille 30 is discharged. This can enrich the usage scenarios of the indoor unit in this embodiment and improve the multi-scenario adaptability of the indoor unit.

[0109] Optionally, refer to Figures 8-9 In the first open state of the air outlet 11, there is a gap between the sliding door 20 and the two sides of the grille 30.

[0110] In this embodiment, in the first open state of the air outlet 11, the airflow at the air outlet 11 is blown out from the air guide channel 33 of the grille 30 and from the gap between the two sides of the grille 30 and the sliding door 20. The airflow blown out from the air guide channel 33 has a gentle breeze effect, which can avoid direct airflow. The airflow blown out from the two sides of the grille 30 can quickly diffuse to both sides, which can also avoid direct airflow, and can also increase the air volume delivered by the indoor unit per unit time, which can meet the air supply requirements in a large space and expand the multi-scenario adaptability of the indoor unit.

[0111] Optionally, refer to Figure 10 In the second open state of the air outlet 11, the sliding door 20 overlaps or approaches the sides of the grille 30.

[0112] In this embodiment, when the air conditioner is turned on and in air supply mode, the user can adjust the sliding door 20 to a second open state according to the air supply requirements of another scenario, such as air supply in a small space. The air guide channel 33 of the grille 30 is connected to the air outlet 11, so that the sliding door 20 overlaps or approaches the two sides of the grille 30. At this time, most of the airflow at the air outlet 11 can only be blown out from the air guide channel 33 of the grille 30, which reduces the air volume of the air conditioner and avoids direct cold air blowing, thus meeting the air supply requirements of a small space and improving the user experience.

[0113] Optionally, when the air conditioner stops blowing air, the sliding door 20 can be adjusted to the second open state. In this state, the air guide channel 33 of the grille 30 is still connected to the air outlet 11, but no airflow is blown out. At this time, the grille surface 32 of the grille 30 with the air guide channel 33 faces outward. The grille surface 32 and the sliding door 20 together form the appearance of the indoor unit, thus creating another form of appearance display effect and realizing the multi-functional adjustment of the air conditioner to adapt to different home scenarios.

[0114] In one possible application scenario, when the user sets the overlapping state of the sliding door 20 and the grille 30 to the air conditioner's on state, it can also be set to the air conditioner's off state simultaneously. Therefore, when the indoor unit starts, there is no need to adjust the state of the sliding door 20 and the grille 30, saving energy consumption during indoor unit startup and improving startup response speed.

[0115] Optionally, refer to Figures 8-9 The grille 30 includes a grille surface 32 forming an air guide channel 33, and the grille surface 32 includes a first grille surface 321 and a second grille surface 322. The grille 30 is rotatably disposed at the air outlet 11. The grille 30 can rotate clockwise or counterclockwise relative to the first plane, so that the first grille surface 321 or the second grille surface 322 of the grille 30 faces outward, so as to quickly switch between the air supply effect of long-distance air delivery in the middle and air expansion on both sides and the ultra-long-distance precise air delivery effect.

[0116] In one alternative implementation, refer to Figure 6 and Figure 8 In the first or second open state of the air outlet 11, the first grille surface 321 of the grille 30 is close to the air duct outlet 121, and the inclined air guide channel 331 is inclined from the middle of the air outlet 11 to both sides along the front and rear direction of the grille 30.

[0117] Therefore, the inclined air guide channel 331 here can serve as an air expansion channel that diffuses the airflow to both sides.

[0118] Optionally, the grille 30 can be configured as an arc-shaped structure that bends in the front-to-back direction, which can further enhance the air expansion effect of the grille 30, expand the air expansion range, improve the temperature uniformity of the space, and meet the needs of rapid temperature control in large spaces.

[0119] In another alternative implementation, refer to Figure 9 In the first or second open state of the air outlet 11, the second grille surface 322 of the grille 30 is close to the air duct outlet 121, and the inclined air guide channel 331 is inclined from both sides of the air outlet 11 towards the center along the front and rear direction of the grille 30.

[0120] Therefore, the inclined air guide channel 331 here can serve as an air gathering channel that concentrates the airflow toward the center.

[0121] Optionally, the grille 30 can be configured as an arc-shaped structure that bends in the front-to-back direction, which can further enhance the wind gathering effect of the grille 30, further extend the air delivery distance of the air conditioner, improve the problem of excessive wind speed attenuation during centralized air delivery, and meet the needs of ultra-long-distance air delivery.

[0122] Optionally, refer to Figure 10 In the second open state of the air outlet 11, the second grille surface 322 of the grille 30 and the sliding door 20 form a continuous transition appearance surface.

[0123] Furthermore, in this embodiment, the grille 30 is designed as an arc-shaped structure, which allows the grille 30 and the sliding door 20 to form a continuous transition surface when the sliding door 20 is in the middle state, thereby improving the appearance and consistency of the indoor unit and meeting the needs of different home scenarios.

[0124] Optionally, refer to Figure 11 With the grille 30 rotatable, and the sliding door 20 closed, the grille 30 can rotate to the side wall of the grille 30 to block the air outlet 11, so that the side wall of the grille 30 and the surface of the sliding door 20 form another form of appearance with a continuous transition.

[0125] Optionally, based on the rotatability of the grille 30, any grille surface 32 of the grille 30 forming the air guide channel 33 can not only be set directly in front of the air outlet 11, but can also be deflected to the left or to the right relative to the first plane by a set angle, so as to deliver air to any area on either side of the indoor unit in a targeted manner, which is suitable for the application scenario of delivering air to any side of the indoor unit over a long distance.

[0126] Optionally, in addition to the rotatability of the grille 30, the grille 30 can also swing left and right to deliver air, making the airflow more evenly diffused.

[0127] Optionally, refer to Figures 12-14 In other alternative embodiments, the grille 30 includes an air guide duct, which includes a first grille plate 34 and a second grille plate 35 arranged at intervals. At least one of the first grille plate 34 and the second grille plate 35 is provided with an inclined air guide channel 331.

[0128] Compared to the single-layer grille in the above embodiments, in this embodiment, the grille 30 includes a double-layer grille plate, which can enhance the structural support performance of the grille 30 and reduce the risk of deformation during long-term use. Airflow passing through the air guide channel 33 of the first grille plate 34 and the second grille plate 35 enhances the softening effect of the grille 30 on the airflow.

[0129] Furthermore, by providing an inclined air guide channel 331 in at least one of the first grille plate 34 and the second grille plate 35, the air guide can have a lateral air guiding or central air gathering effect.

[0130] In one example, both the first grille plate 34 and the second grille plate 35 have inclined air guide channels 331, and the inclined air guide channels 331 on both sides are symmetrically arranged with respect to the center line of the grille 30 in the vertical direction, so that the air guide has the function of double soft wind and double side air expansion, or the air guide has the function of double soft wind and central air gathering.

[0131] In another example, with the first grille 34 facing the air duct 12, the first grille 34 is provided with a straight air guide channel 332, and the second grille 35 is provided with an inclined air guide channel 331 that is inclined to both sides or inclined to the center, which can reduce some wind resistance while achieving air expansion on both sides or air concentration in the center.

[0132] In another example, with the first grille 34 facing the air duct 12, the first grille 34 is provided with an inclined air guide channel 331 that tilts towards the center, and the second grille 35 is provided with an inclined air guide channel 331 that diffuses to both sides. This allows the airflow to gather in the cavity of the air duct through the inclined air guide channel 331 of the first grille 34, and then diffuse to both sides through the inclined air guide channel 331 of the second grille 35, thereby increasing the air volume when expanding to both sides and achieving rapid temperature control in the space.

[0133] Optionally, refer to Figure 14 With the air outlet 11 closed, the two sliding doors 20 and the side wall 36 of the air duct together seal the air outlet 11.

[0134] In this embodiment, with the air outlet 11 closed, the air guide tube rotates so that one sidewall 36 faces outwards and is close to the air duct outlet 121, causing the two sliding doors 20 to approach the sidewall 36 of the air guide tube, thus jointly sealing the air outlet 11. The outer surfaces of the sidewall 36 of the air guide tube and the two sliding doors 20 transition continuously, serving as the exterior surface of the indoor unit, which can improve the appearance and consistency of the indoor unit.

[0135] Optionally, refer to Figures 8-11 The indoor unit of this application also includes multiple sets of air guide plates 40, which are arranged at intervals in the left and right directions. A grille 30 is set in front of the air guide plates 40. The airflow blown out along the air duct 12 passes through the gap formed by two adjacent air guide plates 40 to reach the grille 30 in front of the air outlet 11, and then blows out from the air guide channel 33 of the grille 30.

[0136] Optionally, multiple sets of air guide vanes 40 are rotatably arranged inside the air outlet 11. When the sliding door 20 is closed, the multiple sets of air guide vanes 40 overlap sequentially in the left-right direction; when the sliding door 20 is open, the multiple sets of air guide vanes 40 are spaced apart in the left-right direction.

[0137] In this embodiment, when the air outlet 11 is closed, multiple sets of air guide plates 40 can rotate to the same side, so that the multiple sets of air guide plates 40 are stacked in sequence, which can shorten the space occupied by the air guide plates 40 in the front-back direction.

[0138] When the indoor unit is supplying air, the user can set the air guide plate 40 to be positioned at a set angle, or control the air guide plate 40 to swing back and forth within a certain angle range, so as to achieve the beneficial effects of uniform air supply, ensuring uniform mixing of indoor hot and cold air and expanding the air supply range.

[0139] Optionally, multiple sets of air guide vanes 40 are symmetrically arranged relative to the centerline of the grille 30 in the vertical direction. When the indoor unit is supplying air, and when the first grille surface 321 of the grille 30 is close to the air duct outlet 121, allowing the grille 30 to expand the airflow to both sides, the ends of the multiple sets of air guide vanes 40 near the grille 30 can be pointed to both sides of the grille 30 respectively, which can further promote the airflow blown out of the air duct 12 to diffuse to both sides and further expand the airflow diffusion range.

[0140] Moreover, when the indoor unit is supplying air, and when the second grille surface 322 of the grille 30 is close to the air duct outlet 121, allowing the grille 30 to concentrate air towards the center, the ends of the multiple sets of air guide plates 40 near the grille 30 can all point towards the center of the grille 30, which can concentrate the airflow blown out of the air duct 12 towards the center, further improving the air concentration effect of the indoor unit, extending the air supply distance, and meeting the needs of ultra-long distance air supply scenarios.

[0141] Optionally, refer to Figures 8-11 The indoor unit of this embodiment also includes up-and-down sweeping blades 60 and a dust filter 50. The dust filter 50 is disposed at the air duct outlet 121, the up-and-down sweeping blades 60 are located inside the dust filter 50, and the air guide plate 40 is located in front of the dust filter 50. The up-and-down sweeping blades 60 can swing up and down synchronously to deliver air. By enabling the up-and-down sweeping blades 60 to swing up and down, the concentrated airflow in the air duct 12 can be divided and guided, making the airflow diffusion more uniform.

[0142] Optionally, refer to Figures 8-11 Multiple upper and lower sweeping blades 60 are arranged along the vertical spacing, and at least one upper and lower sweeping blade 60 has a through hole. While the upper and lower sweeping blades 60 swing up and down to sweep the air, a gentle breeze effect can be achieved.

[0143] This application embodiment Figure 10This is used to illustrate an embodiment where some of the upper and lower sweeping blades 60 have through holes, while some of the upper and lower sweeping blades 60 do not have through holes.

[0144] Based on the same inventive concept, this application provides an air conditioner including the indoor unit of the above embodiments.
