[0044] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0045] refer to Figures 1 to 4 The indoor unit housing according to the first aspect of the present invention includes:

[0046] Housing 100, housing 100 having an air inlet 110;

[0047] Dustproof component 200 is movably connected to housing 100 and is used to open or block air inlet 110.

[0048] The drive assembly 300 is connected to the dustproof assembly 200 in a transmission manner. The drive assembly 300 is used to drive the dustproof assembly 200 to open or block the air inlet 110.

[0049] Understandably, when the indoor unit is not in use, the dustproof component 200 can block the air inlet 110 of the casing 100, preventing dust from falling onto the air filter at the air inlet 110, avoiding clogging of the air filter mesh, ensuring the air intake of the indoor unit, and thus ensuring the heating and cooling effects of the indoor unit. On the other hand, when the indoor unit is turned on, the drive component 300 will drive the dustproof component 200 to open the air inlet 110 on the casing 100 to ensure that the indoor unit can operate normally.

[0050] It should be explained that the air filter (not shown in the diagram) is located inside the housing 100, corresponding to the air inlet 110. This means the air filter is positioned below the air inlet 110, so that outside air must pass through both the air inlet 110 and the air filter before entering the housing 100. The air filter is a common feature in indoor units and will not be elaborated further here.

[0051] refer to Figure 1 and Figure 3The dustproof assembly 200 includes multiple dustproof plates 210, each of which is rotatably connected to the housing 100 at both ends along its length. A drive assembly 300 is connected to the multiple dustproof plates 210 and drives them to rotate synchronously, opening or blocking the air inlet 110. Understandably, when the indoor unit is not in use, the drive assembly 300 drives the multiple dustproof plates 210 to rotate synchronously, blocking the air inlet 110 on the housing 100. When the indoor unit is started, the drive assembly 300 drives the multiple dustproof plates 210 to rotate synchronously, opening the air inlet 110 on the housing 100 to ensure that outside air can pass through the air inlet 110 and the air filter into the housing 100. In the first aspect of this utility model, the length direction of the dustproof plate 210 is parallel to the length direction of the housing 100.

[0052] refer to Figure 1 and Figure 2 Each of the multiple dustproof plates 210 has a rotating shaft 211 at both ends along its length. The housing 100 has multiple shaft holes 130, and the multiple rotating shafts 211 pass through the multiple shaft holes 130 respectively. It can be understood that the inner wall of the shaft hole 130 limits the rotating shaft 211, allowing the rotating shaft 211 to rotate within the shaft hole 130, thereby allowing the dustproof plate 210 to rotate.

[0053] refer to Figure 2 and Figure 6 The indoor unit casing also includes a transmission gear set 400, which is connected to multiple dustproof plates 210. A drive assembly 300 can drive the transmission gear set 400 to rotate, causing the multiple dustproof plates 210 to rotate synchronously. The indoor unit casing also includes a rack 340, which is movably mounted on the housing 100 along its length. The teeth of the rack 340 mesh with the transmission gear set 400. The drive assembly 300 can drive the rack 340 to move, causing the rack 340 to drive the transmission gear set 400 to rotate. It can be understood that the output end of the drive assembly 300 is connected to the multiple dustproof plates 210 via the rack 340 and the transmission gear set 400. When multiple dustproof plates 210 need to be flipped, the drive assembly 300 drives the rack 340 to move along its own length. Since the teeth on the rack 340 mesh with the transmission gear set 400, the rack 340 can drive the transmission gear set 400 to rotate, thereby causing the multiple dustproof plates 210 to flip synchronously.

[0054] As another embodiment of the first aspect of this utility model, the indoor unit housing includes a gear belt, which is wound around the transmission gear set 400. The teeth on the inner side of the gear belt mesh with the transmission gear set 400. The drive component 300 drives the gear belt to rotate, so that the gear belt drives the transmission gear set 400 to rotate.

[0055] refer to Figures 5 to 8 The housing 100 has a receiving groove 120, the length direction of which is parallel to the length direction of the rack 340. The rack 340 is movably disposed within the receiving groove 120. The transmission gear set 400 is disposed within the receiving groove 120. A guide block 343 is provided on the side of the rack 340 away from the air inlet 110, the length direction of which is parallel to the length direction of the rack 340. A guide groove 121 is formed on the bottom wall of the receiving groove 120, the length direction of which is parallel to the length direction of the rack 340. The guide block 343 extends into the guide groove 121. It can be understood that the inner wall of the guide groove 121 can abut against the guide block 343 on the rack 340, that is, the inner wall of the guide groove 121 guides the movement of the guide block 343 and the rack 340, so that the rack 340 can move smoothly along its own length direction.

[0056] refer to Figure 3 The indoor unit casing also includes a cover plate 140, which is detachably connected to the inner wall of the storage slot 120 so that the cover plate 140 can cover the storage slot 120. Due to the high airflow velocity in the housing 100 area, the rapidly flowing air can damage the surface protective layer of the transmission gear set 400 and rack 340, exposing them to oxygen, moisture, and other corrosive substances. This accelerates the aging of the transmission gear set 400 and rack 340 and affects their transmission stability. Understandably, the cover 140 can conceal the opening of the storage slot 120, preventing the rack 340 and transmission gear set 400 inside the storage slot 120 from being exposed to rapidly flowing air. This prevents the surface protective layer of the rack 340 and transmission gear set 400 from being damaged by the rapidly flowing air, thereby delaying the aging of the rack 340 and transmission gear set 400 and helping to ensure the transmission stability of the rack 340 and transmission gear set 400. On the other hand, the cover 140 conceals the rack 340 and transmission gear set 400 inside the storage slot 120, preventing them from being directly exposed, making the indoor unit more aesthetically pleasing.

[0057] When the rack 340 and transmission gear set 400 inside the storage slot 120 need to be inspected, the maintenance personnel can remove the cover plate 140, which improves the convenience of maintenance personnel in maintaining the rack 340 and transmission gear set 400. As an embodiment of the first aspect of this utility model, the inner sidewall of the storage slot 120 is provided with multiple buckle holes, and the cover plate 140 is provided with multiple buckle blocks, which can be respectively fastened into the multiple buckle holes.

[0058] refer to Figures 4 to 7 and Figure 12 The transmission gear set 400 includes multiple transmission gears 410, which are respectively connected to multiple dustproof plates 210. All transmission gears 410 mesh with a rack 340, enabling the rack 340 to simultaneously drive the multiple transmission gears 410 to rotate. In the first aspect embodiment of this utility model, a storage groove 120 is disposed in the middle of the air inlet 110, dividing the air inlet 110 into a first air inlet and a second air inlet. Each of the multiple dustproof plates 210 includes a first half and a second half. The multiple first half is used to open or block the first air inlet, and the multiple second half is used to open or block the second air inlet. The first half and the second half are connected by transmission gears 410. The rack 340 can simultaneously drive the multiple transmission gears 410 to rotate synchronously, enabling the multiple first half and the multiple second half to rotate synchronously. In this embodiment of the utility model, the multiple dustproof plates 210 are all parallel to the left-right direction, that is, both the first half and the second half are parallel to the left-right direction. The rack 340 is parallel to the front-to-back direction, and the storage slot 120 is also parallel to the front-to-back direction.

[0059] A receiving slot 120 is located in the middle of the air inlet 110, dividing the air inlet 110 into a first air inlet and a second air inlet. The portion of the air inlet 110 on the left side of the receiving slot 120 is the first air inlet, and the portion of the air inlet 110 on the right side of the receiving slot 120 is the second air inlet. Multiple first halves are rotatably connected to the housing 100 at both ends, and multiple second halves are rotatably connected to the housing 100 at both ends. Each of the first halves is used to open or block the first air inlet, and each of the second halves is used to open or block the second air inlet. The number of transmission gears 410 is the same as the number of first halves, and the multiple first halves and multiple second halves are connected to each other via transmission gears 410.

[0060] Understandably, the drive assembly 300 drives the rack 340 to move in its own direction. Since the rack 340 meshes with multiple transmission gears 410, and the multiple first halves and multiple second halves are connected by transmission gears 410, the rack 340 can drive the multiple transmission gears 410 to rotate synchronously, so that the multiple first halves and multiple second halves can rotate synchronously, thereby enabling the multiple first halves and multiple second halves to open or block the first air inlet and the first air vent simultaneously.

[0061] For details, please refer to Figure 11 Both ends of the first and second halves along their length are provided with rotating shafts 211. The indoor unit casing also includes multiple splined shafts 220, the number of which is the same as the number of transmission gears 410. Splined holes are provided on the rotating shafts 211 opposite to the first and second halves, and splined holes are also provided on the transmission gears 410. The splined shafts 220 pass through the splined holes on the transmission gears 410, the first and second halves, so that the transmission gears 410, the first and second halves are mutually connected through the splined shafts 220. Further details are omitted here.

[0062] In another embodiment of the first aspect of this utility model, the storage slot 120 is located on the left or right side of the air inlet 110, and both ends of the dustproof plate 210 are rotatably connected to the housing 100. The transmission gear set 400 includes multiple transmission gears 410, the number of which is the same as the number of dustproof plates 210. The multiple transmission gears 410 are respectively connected to the rotating shaft 211 on the left or right end of the dustproof plate 210, and all of the multiple transmission gears 410 mesh with the teeth of the rack 340, that is, all of the multiple transmission gears 410 mesh with the first tooth 341 of the rack 340. It can be understood that the rotation drive 310 drives the drive gear 320 to rotate, causing the rack 340 to move in its own direction. Since the rack 340 meshes with multiple drive gears 320 and multiple dustproof plates 210 are respectively connected to multiple drive gears 320, the rack 340 can drive multiple transmission gears 410 to rotate, so that multiple dustproof plates 210 can rotate synchronously, thereby enabling multiple dustproof plates 210 to open or block the air inlet 110.

[0063] refer to Figure 9 and Figure 10The drive assembly 300 includes a rotary drive member 310 and a drive gear 320. The rotary drive member 310 is mounted on the housing 100, and its output end is connected to the drive gear 320. The drive gear 320 meshes with the teeth of the rack 340. The rotary drive member 310 drives the drive gear 320 to rotate, thereby causing the drive gear 320 to move the rack 340. It can be understood that the rotary drive member 310 drives the drive gear 320 to rotate, and because the drive gear 320 meshes with the rack 340, the drive gear 320 can drive the rack 340 to move along its own length. In one embodiment of the first aspect of this utility model, the drive assembly 300 further includes a driven gear 330 and a gear housing. The gear housing is disposed on the housing 100, and the driven gear 330 is rotatably disposed within the gear housing. The driven gear 330 meshes with the teeth of the rack 340 and with the driving gear 320, such that the driving gear 320 is connected to the rack 340 via the meshing of the driven gear 330 and the teeth of the rack 340. In another embodiment of the first aspect of this utility model, the rotary drive member 310 can be a motor, and the output shaft of the motor is connected to the driving gear 320.

[0064] For details, please refer to Figure 8 The rack 340 has a first tooth 341 and a second tooth 342. The first tooth 341 is located on the side of the rack 340 near the air inlet 110 and meshes with the transmission gear set 400. The second tooth 342 is located on the side of the rack 340 away from the air inlet 110 and meshes with the drive gear 320. It can be understood that the upper side of the rack 340 has the first tooth 341, and the lower side of the rack 340 has the second tooth 342. This design makes more efficient use of the installation space of the housing 100, allowing the transmission gear set 400 to be located above the rack 340 and the drive assembly 300 to be located below the rack 340, making the drive assembly 300 easier to install. Specifically, the driven gear 330 meshes with the second tooth 342 of the rack 340.

[0065] An air conditioner according to a second aspect embodiment of the present invention includes an indoor unit casing. The air conditioner also includes an outdoor unit, an indoor unit, a compressor, and an expansion valve. A refrigerant flow circuit is formed between the outdoor unit, the indoor unit, the compressor, and the expansion valve. The outdoor unit, the indoor unit, the compressor, and the expansion valve are all common components in air conditioners and will not be described further here. The air conditioner possesses all the beneficial effects brought by the aforementioned indoor unit casing, which will not be described further here.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] Of course, this utility model is not limited to the above-described embodiments.
