[0033] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0034] Reference below Figure 1-Figure 7 The air conditioner indoor unit 100 according to an embodiment of the present invention is described. The air conditioner indoor unit 100 can be a wall-mounted air conditioner indoor unit. In the following description of the present application, the air conditioner indoor unit 100 is taken as an example to be described as a wall-mounted air conditioner indoor unit. Of course, the air conditioner indoor unit 100 can also be other types of air conditioner indoor units, and is not limited to wall-mounted air conditioner indoor units.

[0035] like Figure 1-Figure 7 As shown, the indoor unit 100 of the air conditioner according to the embodiment of the present invention includes a body 1, an air guide plate 2 and an air sweeping structure 3.

[0036] Specifically, the machine body 1 is formed with an air outlet 11, and the air guide plate 2 is provided on the machine body 1 to open and close the air outlet 11. Figure 1-Figure 7 In the example, the air guide plate 2 can be located in front of the air outlet 11. Here, it should be noted that in the description of the present application, the direction of the air conditioner indoor unit 100 facing the user is referred to as "front", and conversely, the direction away from the user is referred to as "rear". When the air conditioner indoor unit 100 is working, the air guide plate 2 opens the air outlet 11, and the air flow can be sent out through the air outlet 11 to adjust the indoor temperature. When the air conditioner indoor unit 100 stops working, the air guide plate 2 closes the air outlet 11 to prevent external dust, debris, insects, etc. from entering the body 1.

[0037] like Figure 1 and Figure 2 As shown, the wind sweeping structure 3 includes a plurality of wind sweeping blades 31. In the description of the present invention, "plurality" means two or more. The plurality of wind sweeping blades 31 are arranged on a side surface of the wind guide plate 2 adjacent to the center of the body 1 at intervals along the length direction of the wind guide plate 2, and each wind sweeping blade 31 is rotatable. When the air conditioner indoor unit 100 is working, the wind guide plate 2 opens the air outlet 11, and the plurality of wind sweeping blades 31 can swing left and right relative to the wind guide plate 11 to achieve left and right wind sweeping. Therefore, compared with the wind sweeping blades in the related art that are located in the air duct attached to the air outlet, the plurality of wind sweeping blades 31 are arranged on a side surface of the wind guide plate 2 adjacent to the center of the body 1 at intervals, so that the wind sweeping blades 31 are closer to the air outlet 11 of the air conditioner indoor unit 100, and there is no shielding on the air duct, which can effectively ensure the air outlet area of ​​the air outlet 11, and at the same time ensure that when the wind sweeping blades 31 sweep the air, the air volume of the air outlet 11 of the air conditioner indoor unit 100 will not be affected, thereby improving the performance of the air conditioner indoor unit 100.

[0038] According to the air conditioner indoor unit 100 of the embodiment of the present invention, a plurality of sweeping blades 31 are arranged at intervals on a side surface of the air guide plate 2 adjacent to the center of the body 1. Compared with the related art in which the sweeping blades are located in the air duct near the air outlet, the sweeping blades 31 are closer to the air outlet 11 of the air conditioner indoor unit 100 and do not block the air duct, which can effectively ensure the air outlet area of ​​the air outlet 11, thereby ensuring the air outlet volume of the air outlet 11 of the air conditioner indoor unit 100 and improving the performance of the air conditioner indoor unit 100.

[0039] According to some embodiments of the present invention, the wind guide plate 2 includes a first wind guide plate 21 and a second wind guide plate 22, the second wind guide plate 22 is connected to a side of the first wind guide plate 21 away from the center of the body 1, and a receiving space 23 is defined between the second wind guide plate 22 and the first wind guide plate 21, wherein a plurality of wind sweeping blades 31 are arranged on the first wind guide plate 21, and the wind sweeping structure 3 further includes a driving mechanism 32, the driving mechanism 32 is arranged in the receiving space 23, and the driving mechanism 32 is connected to the plurality of wind sweeping blades 31 to drive the plurality of wind sweeping blades 31 to rotate. For example, referring to Figure 1-Figure 3, a plurality of sweeping blades 31 are arranged on a side surface of the first air guide plate 21 adjacent to the center of the body 1 and spaced apart from each other along the length direction of the first air guide plate 21. Compared with the related art in which the sweeping blades 31 are located in the air duct of the air outlet, the convenience of cleaning the sweeping blades 31 is improved, and the air outlet area of ​​the air outlet 11 is guaranteed. The first air guide plate 21 and the second air guide plate 22 can be buckled together by a snap-fit ​​structure to define a receiving space 23. The driving mechanism 32 is installed in the receiving space 23 and drives the plurality of sweeping blades 31 to swing left and right, so as to realize automatic sweeping of the indoor unit 100 of the air conditioner. At the same time, the space between the first air guide plate 21 and the second air guide plate 22 is reasonably utilized, and the interference between the driving mechanism 32 and other surrounding parts can be effectively avoided, so as to ensure the cleanliness of the driving mechanism 32 and extend the service life of the driving mechanism 32.

[0040] Furthermore, if Figure 4 and Figure 7 As shown, a plurality of mating shafts 221 are provided on a side surface of the second air guide plate 22 adjacent to the first air guide plate 21 and spaced apart along the length direction of the second air guide plate 22. A mating column 311 is provided at the bottom of each wind sweeping blade 31. A first mating hole 3111 is formed on the mating column 311. The mating column 311 passes through the first air guide plate 21 and the corresponding mating shaft 221 is mated in the first mating hole 3111. For example, Figure 4 and Figure 7 In the example, the mating column 311 is located at the bottom of the corresponding wind sweeping blade 31, and the mating column 311 may include a plurality of arc segments arranged at circumferential intervals, and the plurality of arc segments jointly define a first mating hole 3111, thereby making the mating column 311 have a certain elastic deformation amount, which is convenient for installation, while ensuring that the mating column 311 can be tightly attached to the mating shaft 221 on the second air guide plate 22 during installation, thereby ensuring that the mating column 311 can rotate around the central axis of the mating shaft 221, and effectively ensuring that the deflection angle of the wind sweeping blade 31 is accurate during operation and is not prone to deviation.

[0041] Optionally, combined Figure 7 The outer side surface of the arc segment can be provided with reinforcing ribs, so as to improve the structural strength of the matching column 311 while ensuring the elastic deformation of the matching column 311.

[0042] A connecting shaft 312 is provided on the radial outer side of the matching column 311. The driving mechanism 32 includes a connecting rod 321, which is arranged in the accommodating space 23 and extends along the length direction of the air guide plate 2. In this way, by arranging the connecting rod 321 in the accommodating space 23, the influence of the connecting rod 321 on the air outlet 11 can be reduced, and the cleaning workload of the user can be reduced. A plurality of connecting holes 3211 are formed on the connecting rod 321, and the plurality of connecting holes 3211 can be arranged at intervals along the length direction of the connecting rod 321. The connecting shafts 312 of the plurality of wind sweeping blades 31 are respectively matched in the plurality of connecting holes 3211. When the connecting rod 321 moves along the length direction of the air guide plate 2, the plurality of wind sweeping blades 31 are driven to rotate around the central axis of the corresponding matching shaft 221 through the matching of the connecting shaft 312 and the connecting hole 3211. When the wind sweeping blade 31 is installed, the matching column 311 of the wind sweeping blade 31 passes through the first wind guide plate 21 and cooperates with the corresponding matching shaft 221. At this time, the connecting shaft 312 passes through the first wind guide plate 21 together with the matching column 311 and cooperates with the corresponding connecting hole 3211 on the connecting rod 321. When the connecting rod 321 moves along the length direction of the wind guide plate 2, the connecting hole 3211 on the connecting rod 321 drives the connecting shaft 312 to rotate around the central axis of the matching shaft 221, thereby driving the wind sweeping blade 31 to swing left and right around the central axis of the matching shaft 221, thereby realizing the left and right wind sweeping of the wind sweeping blade 31.

[0043] Furthermore, if Figure 4 and Figure 5 As shown, the driving mechanism 32 also includes a motor 322, a screw 323 and a nut 324. The motor 322 is fixed in the accommodating space 23, and the motor 322 has an output shaft 3221. One end of the screw 323 is fixedly connected to the output shaft 3221. The screw 323 extends along the length direction of the air guide plate 2. The nut 324 is sleeved outside the screw 323 and is threadedly matched with the screw 323. The nut 324 is connected to the connecting rod 321. Since the nut 324 and the screw 323 are self-locking, the wind sweeping blade 31 connected to the connecting rod 321 is self-locking, which can effectively prevent the user from accidentally changing the deflection angle of the wind sweeping blade 31, and facilitate the user to clean the wind sweeping blade. When the motor 322 is working, the nut 324 moves axially along the screw rod 323 to drive the connecting rod 321 to move along the length direction of the air guide plate 2. The connecting rod 321 drives the connecting shaft 312 of the wind sweeping blade 31 to rotate around the central axis of the matching shaft 221, thereby driving the wind sweeping blade 31 to swing left and right around the central axis of the corresponding matching shaft 221.

[0044] In some optional embodiments, a second mating hole 3212 is formed on one of the nut member 324 and the connecting rod 321, and the second mating hole 3212 is an elongated hole extending in the width direction of the connecting rod 321, and a mating tongue 3241 is provided on the other of the nut member 324 and the connecting rod 321. The mating tongue 3241 cooperates with the second mating hole 3212 to drive the connecting rod 321 to move along the length direction of the air guide plate 2 when the nut member 324 moves along the axial direction of the screw rod 323. The nut member 324 may be provided with a second mating hole 3212, and the connecting rod 321 may be provided with a mating tongue 3241 (not shown); or, the nut member 324 may be provided with a mating tongue 3241, and the connecting rod 321 may be provided with a second mating hole 3212 (such as Figure 4 and Figure 6 As shown). By setting the second matching hole 3212 as a long strip hole, when the second matching hole 3212 is matched with the matching tongue 3241, it can be ensured that the connecting rod 321 has a certain degree of freedom when moving, and the connecting rod 321 can move along the length direction of the air guide plate 2 while also moving along the width direction of the air guide plate 2. Such a setting has a simple structure and is easy to process.

[0045] According to some embodiments of the present invention, two slide grooves 222 are arranged in the accommodation space 23 at intervals along the width direction of the air guide plate 2, and slide grooves 2221 are formed on the surfaces of the two slide grooves 222 facing each other. Two slide rails 3242 are provided on the nut member 324, and the two slide rails 3242 can be slidably matched in the two slide grooves 2221. For example, referring to Figure 5 and Figure 6 Two slide grooves 222 are provided on the surface of the second air guide plate 22 facing the first air guide plate 21. The two slide grooves 222 are spaced apart from each other along the width direction of the second air guide plate 22. Each slide groove 222 is provided with a slide groove 2221. The slide groove 2221 extends along the length direction of the second air guide plate 22. Slide rails 3242 are provided on both sides of the bottom of the nut member 324 in the width direction. When the nut member 324 moves along the length direction of the air guide plate 2, the slide rails 3242 slide along the length direction of the slide groove 2221. The slide groove 222 guides the movement of the nut member 324.

[0046] In some optional embodiments, a first stop member 2222 is provided at one end of at least one slide groove portion 222 away from the motor 322, a second stop member 3243 is provided on the nut member 324, and a third stop member 325 is provided at one end of at least one slide groove portion 222 adjacent to the motor 322, the second stop member 3243 is suitable for abutting against the first stop member 2222 so that the motor 322 reverses to drive the nut member 324 to move toward the direction of the motor 322, and the third stop member 325 is suitable for abutting against the second stop member 3243 so that the motor 322 rotates forward to drive the nut member 324 to move away from the motor 322.

[0047] For example, combined with Figure 2 and Figure 3 The ends of the two slide grooves 222 away from the motor 322 are provided with a first stopper 2222, and the ends of the two slide grooves 222 facing the motor 322 are provided with a third stopper 325. The two side surfaces in the width direction of the nut member 324 are provided with second stoppers 3243 respectively. When the nut member 324 moves to the corresponding position along the length direction of the air guide plate 2, the second stopper 3243 abuts against the first stopper 2222. At this time, the motor 322 originally rotating forward turns to reverse rotation, so that the nut member 324 moves toward the direction of the motor 322, until the second stopper 3243 of the nut member 324 abuts against the third stopper 325. At this time, the reverse motor 322 turns to forward rotation, so that the nut member 324 moves in the direction away from the motor 322. Therefore, through the alternation of forward and reverse rotation of the motor 322, the nut member 324 is driven to move along the length direction of the screw rod 323, so that the wind sweeping blade 31 swings left and right.

[0048] According to some embodiments of the present invention, a mounting seat 223 is provided in the accommodation space 23, a limiting hole 2231 is formed on the mounting seat 223, and the other end of the screw rod 323 (for example, Figure 5 The left end of the 2231 is fitted into the limiting hole 2231. Figure 4 and Figure 5 As shown, a mounting seat 223 is provided at one end of the slide groove portion 222 away from the motor 322, and the mounting seat 223 is located between the two slide groove portions 222, and the screw rod 323 is installed between the two slide groove portions 222. A circular limiting hole 2231 is provided in the middle of the mounting seat 223 so that the end of the screw rod 323 away from the motor 322 can fit in the limiting hole 2231, thereby effectively ensuring the stability of the installation of the screw rod 323 and preventing the screw rod 323 from detaching from the mounting seat 223 when rotating.

[0049] In some optional embodiments, the other end of the screw rod 323 is formed with a positioning hole 3231, a positioning seat 224 is provided on the side of the mounting seat 223 away from the motor 322, and a positioning portion 2241 is provided on the side of the positioning seat 224 facing the screw rod 323, and the positioning portion 2241 is fitted in the positioning hole 3231. Figure 5The end of the screw rod 323 facing the mounting seat 224 is provided with a positioning hole 3231, and the positioning seat 224 is installed on the side of the mounting seat 223 away from the motor 322. The positioning seat 224 is provided with a positioning portion 2241 on a side surface of the mounting seat 223 and opposite to the limiting hole 2231. The positioning portion 2241 is generally conical. When the screw rod 323 is installed, the above-mentioned end of the screw rod 323 passes through the mounting seat 223, and the positioning hole 3231 of the screw rod 323 cooperates with the positioning portion 2241 on the positioning seat 224, so as to further enhance the reliability of the installation of the screw rod 323 and improve the stability of the rotation of the screw rod 323.

[0050] According to some embodiments of the present invention, Figure 4 As shown, an opening 211 is formed at a position of the first air guide plate 21 corresponding to the motor 322, and a detachable cover plate 212 is provided at the opening 211. When the cover plate 212 is removed, the motor 322, the nut member 324, a part of the connecting rod 321 and a part of the screw rod 323 are exposed at the opening 211, thereby effectively improving the convenience of inspecting and repairing the driving mechanism 32.

[0051] The assembly method of the air sweeping structure 3 of the indoor unit 100 of the air conditioner according to the embodiment of the present invention is as follows: the two ends of the air guide plate 2 in the length direction are movably connected to the two air guide plate driving devices 4 through horizontal rotating shafts respectively; after the air sweeping blade 31 passes through the first air guide plate 21, the first matching hole 3111 of the air sweeping blade 31 is sleeved on the matching shaft 221 of the second air guide plate 22; the second matching hole 3212 of the connecting rod 321 is sleeved on the matching tongue 3241 of the nut member 324; the screw rod 323 is screwed Screw in the nut member 324, and the slide rail 3242 of the nut member 324 is installed in the slide groove 2221 of the second air guide plate 22. At the same time, the screw rod 323 passes through the limiting hole 2231 of the mounting seat 223 of the second air guide plate 22, and the positioning hole 3231 of the screw rod 323 cooperates with the positioning portion 2241 of the positioning seat 224; the output shaft 3221 of the motor 322 is inserted into the screw rod 323, and the motor 322 is fixed on the second air guide plate 22, and finally the cover plate 212 is installed on the first air guide plate 21.
