[0045] The invention provides an indoor unit of an air conditioner.

[0046] In the embodiment of the present invention, Figures 1 to 2 , Figures 6 to 7As shown, the air conditioner indoor unit 10 includes a housing 100, an air guide device 200 and a driving mechanism 300, wherein the housing 100 has an air outlet 100a; the air guide device 200 is installed at the air outlet 100a, and the air guide device 200 includes an air guide frame 210 and an air guide assembly 220, wherein the air guide frame 210 is rotatably installed on the housing 100 along a first axis 201, and the air guide assembly 220 is rotatably installed in the air guide frame 210 along a second axis 202, wherein the first axis Line 201 intersects with the vertical projection of the second axis 202 at the air outlet 100a; the driving mechanism 300 is installed on the shell 100, and the driving mechanism 300 includes a first driving device 310 and a second driving device 320, the first driving device 310 is connected to the air guide frame 210 to drive the air guide frame 210 to rotate along the first axis 201, and the second driving device 320 is connected to the air guide assembly 220 to drive the air guide assembly 220 to rotate along the second axis 202.

[0047] Specifically, the air-conditioning indoor unit 10 can be a split floor-standing air-conditioning indoor unit, a split wall-mounted air-conditioning indoor unit, a ceiling unit, a mobile air-conditioning indoor unit or a window-type air-conditioning indoor unit. The following content will be elaborated in detail using the air-conditioning indoor unit 10 as a split floor-standing air-conditioning indoor unit as an example.

[0048] Specifically, Figure 2 As shown, the housing 100 of the air conditioner indoor unit 10 may include a panel 110 and a back plate 120, the panel 110 and the back plate 120 enclose a cavity, and the air guide device 200, the driving mechanism 300, the air duct assembly 400 and the evaporator assembly 500 are installed in the cavity. The panel 110 may be provided with an air outlet 100a, and the back plate 120 may be provided with an air inlet 100b opposite to the air outlet 100a. In order to reduce the entry of dust into the housing 100, an air inlet grille 600 may be installed at the air inlet. The air outlet 100a on the housing 100 may extend in the left-right direction or in the up-down direction. The following content will be mainly described in detail by taking the air outlet 100a extending in the up-down direction as an example.

[0049] like Figures 1 to 5 As shown, the air guide device 200 in the housing 100 can be installed at the air outlet 100a or on the air duct assembly 400. The air guide device 200 is used to guide the air flow up and down and left and right. Figures 6 to 7As shown, the air guide device 200 includes an air guide frame 210, which is rotatably mounted on the housing 100 along a first axis 201. An air guide assembly 220 is mounted in the air guide frame 210, which is rotatable along a second axis 202, and the first axis 201 and the second axis 202 intersect at the vertical projection of the air outlet 100a. The first axis 201 can extend along the up-down direction of the housing 100, or along the left-right direction of the housing 100. The following embodiments will be described by taking the first axis 201 extending along the up-down direction of the housing 100 and the second axis 202 extending along the left-right direction of the housing 100 as an example.

[0050] like Figures 6 to 10 As shown, the driving mechanism 300 in the housing 100 includes a first driving device 310 and a second driving device 320. The first driving device 310 is connected to the air guide frame 210 to drive the air guide frame 210 to rotate left and right along the first axis 201. The air guide assembly 220 in the air guide frame 210 also rotates left and right along the first axis 201 driven by the air guide frame 210, thereby causing the air guide device 200 to deliver air left and right around the first axis 201. The second driving device 320 is connected to the air guide assembly 220 to drive the air guide assembly 220 to rotate along the second axis 202. The air guide assembly 220 swings up and down, thereby causing the air guide assembly 220 to deliver air up and down around the second axis 202, and finally realizing that the air guide device 200 guides air up and down and left and right.

[0051] In the prior art, since the upper and lower air guide louvers are farther from the air outlet 100a than the left and right air guide plates, the upper and lower air guide range is limited. When heating, the hot air density is small and it keeps rising. The wind cannot blow down to the ground, and the user's feet feel cold. When cooling, it is difficult to avoid people blowing upward. Figures 1 to 7 , Fig.10 As shown, the air guide component 220 of the present invention is installed in the air guide frame 210, and the air guide component 220 and the air guide frame 210 are both located on the same plane, thereby guiding the wind, effectively increasing the upper and lower wind sweeping range of the air-conditioning indoor unit 10, and can send the wind to the bottom during heating, and can also blow upward during cooling, which greatly improves the user experience.

[0052] The technical solution of the present invention adopts the method of installing the air guide assembly 220 in the air guide frame 210, thereby reducing the volume of the air guide device 200, reducing the space occupied by the air guide device 200 in the housing 100, and further reducing the materials required for the housing 100, thereby reducing the material cost of the air conditioner indoor unit 10. In addition, the air guide frame 210 and the air guide assembly 220 are both located on the same plane, and the first driving device 310 drives the air guide frame 210 to rotate along the first axis 201, and the second driving device 320 drives the air guide assembly 220 to rotate along the second axis 202, so as to realize the up-down and left-right sweeping of the air guide device 200, effectively increasing the air supply range of the air conditioner indoor unit 10, enhancing the air guide effect of the air guide device 200, and improving the use performance of the air conditioner indoor unit 10.

[0053] The structure of the air guide assembly 220 is various, such as Figures 6 to 9 As shown, in one embodiment, the air guide assembly 220 includes a plurality of first air guide blades 221 intersecting the first axis 201, the plurality of first air guide blades 221 are arranged in parallel and at intervals, the first air guide blades 221 are rotatably connected to the side walls of the air guide frame 210, and the second driving device 320 is connected to the first air guide blades 221 to drive the first air guide blades 221 to rotate along the second axis 202.

[0054] The first wind guide blade 221 extends laterally, and multiple first wind guide blades 221 are arranged in parallel and at intervals in the wind guide frame 210. At the same time, the multiple first wind guide blades 221 are rotatably connected to the side wall of the wind guide frame 210. The second driving device 320 is connected to the multiple first wind guide blades 221. When the second driving device 320 drives the multiple first wind guide blades 221 to rotate along the second axis 202, the multiple first wind guide blades 221 deflect up and down, thereby achieving an up and down guiding effect on the wind.

[0055] There are many structures for the second device to drive the first wind guide blade 221 to rotate, such as Figure 8 and Fig.11 As shown, in one embodiment, the second driving device 320 includes a connecting rod 321 and a second motor 322 connected to the connecting rod 321, the first wind guide blade 221 is rotatably connected to the connecting rod 321, and forms a third axis (not shown), the third axis deviates from the second axis 202, and the second motor 322 is used to drive the connecting rod 321 to move along the direction of the first axis 201.

[0056] The connecting rod 321 of the second driving device 320 connects a plurality of first wind guide blades 221 and the second motor 322. A third axis is formed at the connection between the connecting rod 321 and the first wind guide blade 221. The third axis is parallel to the second axis 202. When the second electrode drives the connecting rod 321 to move downward, since the third axis deviates from the second axis 202, a torque is formed between the connecting rod 321 and the first wind guide blade, and the first wind guide blade 221 swings upward under the pull of the connecting rod 321, thereby realizing upward wind guidance. Similarly, when the connecting rod 321 moves upward, the first wind guide blade 221 swings downward under the push of the connecting rod 321, thereby realizing downward wind guidance. The connecting rod 321 has high transmission stability and good reliability.

[0057] It can be understood that the second motor 322 is used to provide a driving force for the first air guide blade 221 to rotate. The second motor 322 can be a stepping motor or a servo motor.

[0058] Since the first driving device 310 drives the air guide frame 210 to rotate left and right to guide the air left and right, and the second driving device 320 drives the first air guide blades 221 in the air guide frame 210 to rotate up and down to guide the air up and down, when the air guide frame 210 rotates left and right, the second motor 322 of the second driving device 320 can rotate left and right with the air guide frame 210, or can not rotate left and right with the air guide frame 210. Figure 8 and Fig.11 As shown, in one embodiment, the air guide frame 210 is provided with a rotating shaft 211 located on the first axis 201, and the air guide frame 210 is rotatably installed on the shell 100 through the rotating shaft 211, and the rotating shaft 211 is hollow; the second driving device 320 also includes a shaft rod 323 passing through the rotating shaft 211, and the shaft rod 323 has a first end 323a and a second end 323b, the first end 323a is connected to the second motor 322, the second end 323b passes through the rotating shaft 211 and is connected to the connecting rod 321, and the second motor 322 is used to drive the shaft rod 323 to move on the first axis 201.

[0059] The air guide frame 210 is rotatably connected to the housing 100 through the rotating shaft 211, and the housing 100 supports the air guide frame 210. The rotating shaft 211 is provided with a shaft rod 323 to limit the shaft rod 323. When the air guide frame 210 rotates left and right, the rotating shaft 211 rotates left and right on the housing 100, and the shaft rod 323 can rotate left and right along with the rotating shaft 211. Therefore, the second motor 322 does not move in the housing 100, thereby preventing the second motor 322 from interfering with other components in the housing 100 and causing damage. The first end 323a of the shaft rod 323 is connected to the second motor 322, and the second end 323b of the shaft rod 323 is connected to the connecting rod 321. When the second motor 322 drives the shaft rod 323 to move in the up and down direction, the connecting rod 321 also moves up and down, realizing the up and down rotation of the first air guide blade 221, and realizing the up and down wind guiding.

[0060] When the wind guiding device 200 guides the wind left and right, the second motor 322 can rotate along the first axis 201 or can remain stationary. Figures 6 to 8 , Fig.11 As shown, in one embodiment, the connecting rod 321 deviates from the first axis 201 , and the connecting rod 321 is connected to the shaft rod 323 via a transmission rod 324 .

[0061] By deviating from the first axis 201 through the connecting rod 321, the transmission rod 324 connects the connecting rod 321 and the shaft rod 323 respectively. When the air guide frame 210 rotates left and right, the first air guide blade 221 in the air guide frame 210 also rotates left and right, and the connecting rod 321 connecting the first air guide blade 221 also rotates left and right. The transmission rod 324 connecting the connecting rod 321 and the shaft rod 323 can rotate left and right. At this time, the second motor 322 can rotate left and right, or it can remain stationary.

[0062] On the basis of the above embodiment, the transmission rod 324 includes a first transmission part 324 a and a second transmission part 324 b , the first transmission part 324 a is rotatably connected to the shaft 323 , and the second transmission part 324 b is connected to the connecting rod 321 .

[0063] Since the first transmission part 324a is rotatably connected to the shaft 323, when the connecting rod 321 drives the transmission rod 324 to rotate left and right, the transmission rod 324 moves around the shaft 323, and the shaft 323 and the second motor 322 remain stationary, thereby achieving that no matter whether the air guide device 200 guides the air up and down or left and right, the second motor 322 is always stationary, and the second motor 322 can be fixed in the shell 100 to prevent the air guide frame 210 from shaking during movement and causing noise.

[0064] There are many structures for realizing the rotational connection between the first transmission part 324a and the shaft 323. The first transmission part 324a may be provided with a receiving groove, and the shaft 323 may be rotatable in the receiving groove, or the first transmission part 324a may be installed with other structures, and the shaft 323 may be rotatable on the first transmission part 324a. In one embodiment, a cover plate 325 is rotatably installed on the first transmission part 324a, and the cover plate 325 and the first transmission part 324a are used to clamp or release the second end 323b.

[0065] The cover plate 325 and the first transmission part 324a may be provided with grooves. When the cover plate 325 is covered on the first transmission part 324a, the two grooves enclose to form a receiving groove for accommodating the second end 323b of the shaft rod 323, and the shaft rod 323 can rotate in the receiving groove. When the wind is guided left and right, the connecting rod 321 drives the transmission rod 324 to rotate around the shaft rod 323, so that the shaft rod 323 and the second motor 322 are stationary. When the wind is guided up and down, the second motor 322 drives the shaft rod 323 to move up and down, thereby driving the transmission rod 324 and the connecting rod 321 to move up and down, and then pushing or pulling the first wind guide blade 221 to rotate up and down, that is, the transmission rod 324 moves up and down together with the shaft rod 323 in the up and down direction.

[0066] It should be noted that there are multiple ways for the cover plate 325 and the first transmission part 324a to clamp and release the shaft rod 323. One end of the cover plate 325 may be rotatably connected to one end of the first transmission part 324a, and the other end of the cover plate 325 may be connected to the other end of the first transmission part 324a via a snap-fit, thereby realizing the operation of quick installation and disassembly of the shaft rod 323.

[0067] Since the first air guide blade 221 is rotatably connected to the side wall of the air guide frame 210, when the first air guide blade 221 rotates upward or downward, the connecting rod 321 is driven to move toward the outside of the air outlet 100a, that is, the distance between the connection between the first air guide blade 221 and the air guide frame 210 and the connecting rod 321 becomes smaller. In order to make the first air guide blade 221 rotate up and down smoothly, in one embodiment, a sliding groove (not shown) extending from the air inlet side toward the air outlet side is provided on the second transmission part 324b, and the connecting rod 321 can slide in the sliding groove.

[0068] By providing a sliding groove on the second transmission part 324b, the connecting rod 321 has a certain movable space on the second transmission part 324b. When the first air guide blade 221 rotates up and down, the connecting rod 321 slides on the second transmission part 324b and approaches the first air guide blade 221, thereby achieving smooth rotation of the first air guide blade 221 in the up and down directions, avoiding the connection between the first air guide blade 221 and the air guide frame 210 and the connecting rod 321 from being unadjustable, and preventing the connecting rod 321 from breaking when pushing and pulling the first air guide blade 221, thereby increasing the service life of the connecting rod 321.

[0069] There are many ways for the second motor 322 to drive the shaft 323 to move up and down, such as Figure 8 and Fig.11 As shown, in one embodiment, the first end 323a of the shaft 323 is provided with a rack, and the second driving device 320 also includes a gear 326 installed on the second motor 322, and the gear 326 is engaged with the rack. The second motor 322 is used to drive the gear 326 to rotate to drive the shaft 323 to move along the direction of the first axis 201.

[0070] Since a certain push-pull force is required to drive the first air guide blade 221 to rotate, a gear 326 is installed on the second motor 322, and the gear 326 is meshed with the rack on the shaft 323. When the second motor 322 drives the gear 326 to rotate, the gear 326 stably drives the shaft 323 to rise or fall, thereby driving the connecting rod 321 to rise or fall stably, and then pulling or pushing the first air guide blade 221 on the connecting rod 321 to rotate, ensuring the stability of the lifting movement of the gear 326 driving the rack, and also ensuring the stable movement of the first air guide blade 221, avoiding insufficient force to push the shaft 323 to rise, resulting in a small rotation angle of the first air guide blade 221, limiting the upper and lower air supply range of the air conditioner indoor unit 10. At the same time, the second motor 322 is not in the air outlet 100a, and the second motor 322 will not block the air flow, thereby improving the air outlet efficiency.

[0071] The first driving device 310 that drives the air guide frame 210 to rotate left and right has various structures, such as Figure 6 , Figure 8 and Fig.12 As shown, in one embodiment, the first driving device 310 includes an adapter 311 and a first motor 312, the adapter 311 includes a sleeve 311a and a latch 311b, the air guide frame 210 has a first side plate 212 intersecting the first axis 201, and the first side plate 212 is clamped between the sleeve 311a and the latch 311b; the first motor 312 is connected to the sleeve 311a to drive the sleeve 311a to drive the air guide frame 210 to rotate along the first axis 201.

[0072] The adapter and the first motor 312 are installed at one end of the air guide frame 210, and the rotating shaft 211 is installed at the other end. The first side plate 212 of the air guide frame 210 is fixed between the shaft sleeve 311a and the latch 311b through the shaft sleeve 311a and the latch 311b. When the first motor 312 drives the shaft sleeve 311a to rotate left and right, the air guide frame 210 also rotates left and right to ensure that the connecting rod 321 does not interfere with other components when the air is guided left and right. It can be understood that the first motor 312 is used to provide a driving force for the rotation of the air guide frame 210, and the first motor 312 can be a stepping motor or a servo motor.

[0073] Furthermore, if Fig.12 As shown, in one embodiment, a through hole (not shown) is formed on the first side plate 212, and the latch 311b passes through the through hole to be connected to the shaft sleeve 311a.

[0074] By opening a through hole on the first side plate 212, when installing the air guide device 200, the latch 311b can pass through the through hole and quickly connect with the shaft sleeve 311a, which is easy to disassemble and assemble, greatly improves the assembly efficiency, and is also convenient for users to disassemble and wash. It can be understood that there are many ways to connect the shaft sleeve 311a and the latch 311b, which can be a snap connection between the shaft sleeve 311a and the latch 311b, or a threaded connection between the shaft sleeve 311a and the latch 311b, as long as the first side plate 212 of the air guide frame 210 can be fixed between the shaft sleeve 311a and the latch 311b.

[0075] In order to obtain better left and right wind guiding effect, such as Figures 6 to 9 As shown, in one embodiment, the wind guide assembly 220 further includes a plurality of second wind guide blades 222 intersecting the second axis 202 , and the second wind guide blades 222 are connected to the plurality of first wind guide blades 221 .

[0076] The second air guide blade 222 extends vertically, and by providing a plurality of second air guide blades 222, the air flow is dispersed, so that the overall air output is uniform, soft and comfortable, and the left and right air guide directions are ensured at the same time, thereby improving the left and right air guide effect of the air guide assembly 220. In addition, each second air guide blade 222 is connected to a plurality of first air guide blades 221, and when the first air guide blade 221 rotates left and right under the drive of the air guide frame 210, the second air guide blade 222 also rotates left and right, thereby guiding the wind left and right. While the plurality of second air guide blades 222 play the role of guiding the wind, the occupied space is reduced, the space in the housing 100 is saved, and the structure of the air conditioner indoor unit 10 can be more compact.

[0077] Since the first air guide blade 221 is connected to the second air guide blade 222, the connecting rod 321 is used to push or pull the first air guide blade 221 to rotate up and down, so the connecting rod 321 can be connected to the first air guide blade 221 or the second air guide blade 222. Figures 6 to 7 , Fig.13 As shown, in one embodiment, an extension portion 223 is formed at one end of the second air guide blade 222 close to the air inlet side, and the extension portion 223 is rotatably connected to the connecting rod 321 .

[0078] The connecting rod 321 is rotatably connected with the extension part 223. When the connecting rod 321 rises or falls, the extension part 223 is pushed upward or pulled downward, driving the second air guide blade 222 to move, so that the first air guide blade 221 connected to the second air guide blade 222 rotates up and down to guide the airflow. Since the first air guide blade 221 is extended horizontally, the first air guide blade 221 and the connecting rod 321 are arranged to intersect. If the first air guide blade 221 is connected to the connecting rod 321, when the connecting rod 321 moves up and down, the connecting rod 321 has a pulling force in the thickness direction of the first air guide blade 221, which easily causes the first air guide blade 221 to bend and deform. It should be noted that the first air guide blade 221 and the second air guide blade 222 can be arranged in an integrated manner, which greatly improves the assembly efficiency.

[0079] In order to obtain better wind guiding effect, Figures 1 to 8 As shown, in one embodiment, the air guide assembly 220 is arranged in a frame shape. The air guide assembly 220 in the air guide frame 210 is arranged in a frame shape, and may be a plurality of first air guide blades 221 connected with a plurality of second air guide blades 222 to form an air guide inner frame, so that the overall air outlet of the air guide device 200 is softer and more comfortable, thereby ensuring the left and right and up and down air guide directions, and improving the air guide effect of the air guide assembly 220. It is understandable that the number of air guide inner frames may be multiple, and the multiple air guide inner frames are arranged at intervals in the air guide frame 210. A plurality of reinforcing ribs may be provided on the air guide frame 210 to enhance the strength of the air guide frame 210 and ensure the stability of the air guide frame 210 when it moves. The reinforcing ribs may separate the air guide inner frames.

[0080] In order to obtain a larger wind guide range in the up and down directions, such as Figures 6 to 7 As shown, in one embodiment, the first air guide blade 221 is provided with a avoiding notch 221a corresponding to the connecting rod 321. By providing the avoiding notch 221a on the first air guide blade 221, it is ensured that when the first air guide blade 221 rotates up and down to the maximum angle, an avoiding space is provided for the first air guide blade 221, and the first air guide blade 221 does not interfere with the connecting rod 321.

[0081] Considering that hot air has a low density and rises continuously, in order to make the hot air blow to the user's feet during heating, Fig.10 , Fig.13 As shown, in one embodiment, the end of the first air guide blade 221 near the air outlet side is bent downward. This bending arrangement increases the downward air supply range of the air guide device 200. When the hot air flow is blown out from the housing 100 through the air guide device 200, it blows downward first, which can warm the user's feet and improve the user's experience. It should be noted that the multiple first air guide blades 221 at the lower part of the housing 100 can be bent downward to specifically supply air to the user's feet.

[0082] The present invention further provides an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit 10, wherein the air conditioner outdoor unit is connected to the air conditioner indoor unit 10 via a refrigerant pipe. The specific structure of the air conditioner indoor unit 10 refers to the above embodiment, and since the air conditioner indoor unit 10 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0083] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
