[0029] Figure 1 It is a schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the utility model, and the figure also illustrates the front and back, left and right, up and down directions of the air conditioner indoor unit 20, wherein the lateral direction of the air conditioner indoor unit 20 corresponds to its left and right direction. Figure 2 yes Figure 1 A schematic diagram of a baffle assembly 30 of an indoor unit 20 of an air conditioner is shown. Figure 3 yes Figure 1 A partial cross-sectional schematic diagram of an air conditioner indoor unit 20 is shown.

[0030] The air conditioner indoor unit 20 of this embodiment generally includes a housing 21 and a baffle assembly 30. An air inlet is provided at the top of the housing 21, and the baffle assembly 30 is rotatably disposed at the air inlet and has a rotation axis extending in the lateral direction of the air conditioner indoor unit 20 and close to the front end or rear end thereof. The baffle assembly 30 has a first position for closing the air inlet and a second position with an end away from the rotation axis being higher than the first position.

[0031] The baffle assembly 30 includes a main board portion 31, a ventilation portion 32 and two side plate portions 33. The main board portion 31 is located at the air inlet when the baffle assembly 30 is in the first position to close the air inlet. The ventilation portion 32 is located at the lower side of the main board portion 31 away from one end of the rotating shaft, and one or more ventilation holes are opened on the surface, so that the air conditioner indoor unit 20 can take in air from the ventilation holes when the baffle assembly 30 is in the second position; the two side plate portions 33 are respectively located at the lower sides of the two lateral ends of the main board portion 31, and are connected to the ventilation portion 32, so that the air conditioner indoor unit 20 can be prevented from taking in air from the lateral sides of the baffle assembly 30 when the baffle assembly 30 is in the second position.

[0032] Figure 3 The first position of the baffle assembly 30 is indicated by a dotted line, and the second position of the baffle assembly 30 is indicated by a solid line. The baffle assembly 30 rotates around its own rotation axis close to the front end or the rear end, and as indicated by the arrow, rotates from the first position indicated by the dotted line to the second position indicated by the solid line.

[0033] refer to Figure 2As shown, the baffle assembly 30 includes a main plate portion 31, a ventilation portion 32 and two side plate portions 33. The shape of the main plate portion 31 is adapted to the shape of the air inlet of the air conditioner indoor unit 20, so that when the baffle assembly 30 is located in the first position, the main plate portion 31 is as shown in FIG. Figure 1 As shown, it is located at the air inlet and blocks dust or other debris from falling into the air inlet. The ventilation part 32 is located at the lower side of the main board part 31, away from one end of the rotating shaft, so when the baffle assembly 30 rotates from the first position to the second position, the ventilation part 32 will be lifted upward. One or more ventilation holes are opened on the surface of the ventilation part 32. When the baffle assembly 30 is located at the second position, the ventilation holes are higher than the edge of the air inlet of the air conditioner indoor unit 20, so that the air conditioner indoor unit 20 can take in air from the ventilation holes.

[0034] Figure 2 The side plate portion 33 on one side of the baffle assembly 30 is shown in the figure. It can be understood that there is also a side plate portion 33 on the other side of the baffle assembly 30 that is blocked in the figure. The side plate portion 33 is located at the lower side of the two lateral ends of the main board portion 31 and is connected to the ventilation portion 32, so that when the baffle assembly 30 is located in the second position, the air conditioner indoor unit 20 is prevented from entering the air from the two lateral sides of the baffle assembly 30. The ventilation portion 32 is formed by extending in the lateral direction and its two ends are flush with the two ends of the main board portion 31, and the two side plate portions 33 are formed by extending from the lower side of the main board portion 31 to the end away from the rotation axis and are connected to the two lateral ends of the ventilation portion 32.

[0035] Generally, the baffle assembly 30 can be an integrally molded part, that is, the main board part 31 can be regarded as the basis of the baffle assembly 30, the two side plate parts 33 extend downward from the two lateral ends of the main board part 31, and the ventilation part 32 extends downward from the end of the main board part 31 away from the rotation axis.

[0036] When the air conditioner is not working, the baffle assembly 30 is located at the first position and the main board portion 31 closes the air inlet of the air conditioner indoor unit 20, thereby preventing dust from falling into the air inlet. When the air conditioner needs to take in air, the baffle assembly 30 rotates to the second position where the end away from the rotating shaft is higher than the first position, that is, the ventilation portion 32 is raised, and the vent is raised above the air inlet of the air conditioner indoor unit 20 (when the baffle assembly 30 is located at the first position, the vent is hidden below the air inlet, or inside the housing 21). When the air conditioner indoor unit 20 takes in air, the air flow flows into the baffle assembly 30 from the side where the ventilation portion 32 is located through the vent, and enters the air conditioner indoor unit 20 from the bottom of the main board portion 31. With the cooperation of the side plate portion 33, the air conditioner indoor unit 20 can only take in air from the side where the ventilation portion 32 is located.

[0037] It should be noted that "one end" or "both ends" of the main board portion 31 are not strictly limited to the ends at the extreme ends, but include positions close to the ends. The description of "one end" or "both ends" is only for ease of understanding and to make the text description more concise.

[0038] In some optional embodiments, when the baffle assembly 30 is located at the second position, the lower end of the ventilation portion 32 is close to the edge of the air inlet. Figure 3 As shown, when the baffle assembly 30 is in the second position, the ventilation portion 32 can be tilted downward and backward, and the surface of the ventilation portion 32 can be either a flat surface or a curved surface that is concave toward one end of the rotation axis. The closer the lower end of the ventilation portion 32 is to the edge of the air inlet, the smaller the gap formed therebetween, and the less air leakage at the gap of the air conditioner indoor unit 20.

[0039] In some optional embodiments, when the baffle assembly 30 is located at the second position, the lowermost end of the vent is higher than the air inlet. When there are multiple vents, the lowermost end of the vent refers to the lowermost end of any vent.

[0040] When the air conditioner indoor unit 20 is not in operation, the baffle assembly 30 can prevent dust above the air inlet from falling into the air conditioner indoor unit 20, and naturally dust will also fall onto the surface of the housing 21 around the air inlet. When the air conditioner indoor unit 20 is inletting air, the baffle assembly 30 is located at the second position, at which time the lowermost end of the vent is higher than the air inlet, which can reduce or even prevent dust falling on the surface of the housing 21 in front of the ventilation portion 32 from being sucked into the air conditioner indoor unit 20.

[0041] In some optional embodiments, the air conditioner indoor unit 20 further includes a driving device for driving the baffle assembly 30 to move between the first position and the second position.

[0042] The drive device may be a gear transmission. Figure 4 yes Figure 1 The partial schematic diagram of the air conditioner indoor unit 20 is shown. In order to show the driving device of the air conditioner indoor unit 20, the shell 21 of the air conditioner indoor unit 20 is hidden. However, it can be understood that the driving device is arranged inside the shell 21.

[0043] The gear transmission device is arranged on one or both lateral sides of the baffle assembly 30, and includes a driving gear 23 and a driving motor 24 for driving the driving gear 23 to rotate. The baffle assembly 30 also includes a transmission gear 36, which is arranged on the side plate portion 33 on the same side as the driving device and meshes with the driving gear 23. The driving device drives the transmission gear 36 to rotate through the driving gear 23, thereby driving the baffle assembly 30 to move between the first position and the second position.

[0044] The gear transmission device is preferably arranged on both lateral sides of the baffle assembly 30, and a transmission gear 36 is respectively arranged on the two side plate parts 33 of the baffle assembly 30, and each side has a driving device to drive it to rotate. The two transmission gears 36 rotate coaxially and the two driving devices rotate synchronously. In the above embodiment, the rotation axis of the baffle assembly 30 is coaxial with the transmission gear 36.

[0045] The driving device may also be an electric lifting rod, one end of which is fixed in the housing 21 and the other end is fixed on the baffle assembly 30 to drive the baffle assembly 30 to move between the first position and the second position. The number and setting position of the electric lifting rods can be flexibly adjusted.

[0046] In such embodiments, the rotation axis of the baffle assembly 30 can be located at the end of the main board portion 31, so that when the end away from the rotation axis rises and falls with the rotation, the main board portion 31 close to the rotation axis will not rise or fall, and thus the gap between the air inlet and the baffle assembly 30 on this side will not increase.

[0047] The driving device may naturally also be other electric devices, which is not limited here.

[0048] In some optional embodiments, the rotation axis is close to the front end of the baffle assembly 30, that is, when the baffle assembly 30 rotates to the second position, the air inlet is toward the rear side of the air conditioner indoor unit 20. The advantage of this arrangement is that the air inlet is not directed toward the front of the air conditioner indoor unit 20, resulting in the air conditioner indoor unit 20 opening "openings" at the same time on both the upper and lower sides when working, so it is more beautiful.

[0049] However, taking practicality into consideration, for some air conditioner indoor units 20 whose rear end of the air inlet is close to the rear end of the shell 21 (wall position), the rotating axis is preferably close to the rear end of the baffle assembly 30, that is, the air inlet part faces the front side of the air conditioner indoor unit 20, thereby ensuring that the air conditioner indoor unit 20 has a more stable air intake volume.

[0050] In some optional embodiments, reference Figure 2 As shown, the baffle assembly 30 also includes a bottom plate portion 34, which is connected to the lower side of the main plate portion 31, the lower ends of the two side plates 33 and the lower end of the ventilation portion 32, and has one or more openings on the surface. When the baffle assembly 30 is located at the second position, the air flow sucked into the indoor unit 20 of the air conditioner will successively pass through the vents on the ventilation portion 32 and the openings on the bottom plate portion 34, and then enter the indoor unit 20 of the air conditioner.

[0051] The shapes of the opening on the bottom plate portion 34 and the vent on the vent portion 32 can be flexibly set as needed, and can be as follows: Figure 2As shown, multiple rows are evenly distributed in the horizontal direction, and multiple rows are arranged. It can also form a strip, a grid, a mesh, etc. extending horizontally. The ventilation part 32 can be set as a detachable structure. For example, a slide groove can be set up and down so that the ventilation part 32 can be pulled horizontally relative to other parts of the baffle assembly 30, or it can be fixed with a buckle. If needed, an air freshener or activated carbon can be placed on the bottom plate part 34 to improve the air quality.

[0052] In some optional embodiments, when the opening on the bottom plate portion 34 is in the shape of a strip extending in the transverse or front-to-back direction, the solid portion of the bottom plate portion 34 may not be directly connected to the main plate portion 31 , the ventilation portion 32 and the two side plate portions 33 .

[0053] The bottom plate portion 34 forms an angle with the surface of the main plate portion 31, and the rotation angle of the baffle assembly 30 between the first position and the second position can usually be set to be equal to the angle. That is, when the baffle assembly 30 is in the first position, the main plate portion 31 is located at the air inlet of the air conditioner indoor unit 20, and when the baffle assembly 30 is in the second position, the bottom plate portion 34 is located at or parallel to the air inlet.

[0054] In some optional embodiments, a dust filter is provided at the vent. The dust filter can filter the airflow passing through and can replace the dust filter provided inside the air conditioner indoor unit 20. When the number of vents is small (e.g., one to three) and the size of each vent is large, a detachable dust filter can be provided at each vent to facilitate the user to clean the dust filter. The dust filter can be detachable by sliding a chute, fixing with a buckle, or other setting methods.

[0055] When there are a large number of ventilation openings, a dust filter can be provided to cover each ventilation opening, or the dust filter can be fixedly provided at each ventilation opening.

[0056] The baffle assembly 30 itself can also be detachably arranged relative to the shell 21. The baffle assembly 30 and the shell 21 are mainly fixed at the rotation axis position. Therefore, an upwardly opened snap-on structure can be set at the top of the shell 21 and the rotation axis position of the baffle assembly 30 to facilitate disassembly, assembly and cleaning of the baffle assembly 30.

[0057] Figure 5 is a schematic block diagram of an air conditioner 10 according to an embodiment of the present invention.

[0058] refer to Figure 5 As shown, the air conditioner 10 generally includes an air conditioner indoor unit 20 disposed indoors and an air conditioner outdoor unit 40 disposed outdoors, and the two are connected by a refrigerant pipeline. Among them, the air conditioner indoor unit 20 is usually a wall-mounted air conditioner indoor unit 20.

[0059] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
