The blades are designed as a hollow structure with an air gap, which significantly reduces the heat transfer rate between the two sides of the blades, thus minimizing the likelihood of condensation. The swivel mechanism can also change the airflow direction: driven by a motor, the blades can swing left and right, altering the airflow direction. This not only allows for better circulation of hot and cold air but also increases airflow, resulting in a more uniform temperature within the room.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0059] Wall-mounted air conditioners typically employ a swivel mechanism composed of several blades to guide the airflow exiting the air vents. The blades are designed as a hollow structure with an air gap, which significantly reduces the heat transfer rate between the two sides of the blades, thus minimizing the likelihood of condensation. The swivel mechanism can also change the airflow direction: driven by a motor, the blades can swing left and right, altering the airflow direction. This not only allows for better circulation of hot and cold air but also increases airflow, resulting in a more uniform temperature within the room.

[0060] The existing louvered devices vibrate when the air conditioner outputs a large volume of air, causing the airflow to deviate and resulting in a poor user experience.

[0061] To address the aforementioned problems, this application provides a swivel device for an air conditioner. The air conditioner 100 generally includes an indoor unit 101 and an outdoor unit 102 connected to each other. The indoor unit 101 generally includes a housing 103 and a control device 104, with the control device 104 mounted on the housing 103. The swivel device 200 generally includes multiple swivel blades 201, a fixing mechanism 202, a transmission mechanism 203, and an anti-vibration component 229. The fixing mechanism 202 is installed inside the housing 103, and the multiple swivel blades 201 are integrally formed and rotatably mounted on the fixing mechanism 202. The transmission mechanism 203 is drive-connected to the multiple swivel blades 201 and communicatively connected to the control device 104 to control the rotation of the multiple swivel blades 201. The anti-vibration component 229 is disposed on the fixing mechanism 202 and the swivel blades 201 to prevent the multiple swivel blades 201 from vibrating.

[0062] The air conditioner swing blade device of the present invention fixes the swing blade 201 by setting the anti-vibration component 229 on the fixing mechanism 202 and the swing blade 201. When the air conditioner 100 has a large air volume, the swing blade 201 is more stable and will not vibrate, so the air outlet will not deviate, thereby improving the user experience.

[0063] The louver device for air conditioning and the air conditioner of this application are described below with reference to Figures 1 to 6.

[0064] Referring to Figures 1 to 6, a first aspect of this application provides a swivel device for an air conditioner. The air conditioner 100 generally includes an indoor unit 101 and an outdoor unit 102 connected to each other. The indoor unit 101 generally includes a housing 103 and a control device 104, with the control device 104 mounted on the housing 103. This air conditioner 100 is a conventional air conditioner; the indoor unit 101 can be a floor-standing unit or a wall-mounted unit. This application uses a wall-mounted unit as an example. It should be noted that although this application does not mention other structures of the air conditioner 100, it includes other structures of conventional air conditioners, such as compressors, condensers, and evaporators. The swivel device 200 generally includes multiple swivel blades 201, a fixing mechanism 202, a transmission mechanism 203, and an anti-vibration assembly 229. The fixing mechanism 202 is installed inside the housing 103. Multiple oscillating blades 201 are integrally formed and rotatably mounted on the fixing mechanism 202. The integrally formed blades 201 have no burrs, preventing jamming during rotation. The blades 201 are equidistant and identical in structure. The transmission mechanism 203 is connected to the multiple oscillating blades 201 and is communicatively connected to the control device 104 to control the direction of the blades 201, thus changing the wind direction. An anti-vibration component 229 is installed on the fixing mechanism 202 and the blades 201 to prevent vibration of the blades 201.

[0065] The air conditioner swing blade device of the present invention fixes the swing blade 201 by setting the anti-vibration component 229 on the fixing mechanism 202 and the swing blade 201. When the air conditioner 100 has a large air volume, the swing blade 201 is more stable and will not vibrate, so the air outlet will not deviate, thereby improving the user experience.

[0066] In this embodiment, the control device 104 is an existing controller, which is embedded inside the housing 103 and fixed to the housing 103 with screws. The control device 104 stores an existing control program. The transmission mechanism 203 and the control device 104 are connected by a connecting cable for controlling the operation of the transmission mechanism 203.

[0067] Referring to Figures 3 and 6, in the preferred embodiment of the louver device for the air conditioner described above, the anti-vibration assembly 229 includes a louver insertion hole 230 and a plurality of insertion posts 231. Specifically, a louver insertion hole 230 is provided inside the lower end of each louver 201, and the plurality of insertion posts 231 are constructed on the fixing mechanism 202 for corresponding to and inserting into the louver insertion hole 230, thereby preventing the louver 201 from vibrating when the air conditioner 100 has a large airflow.

[0068] In this embodiment, the leaf insertion hole 230 is a circular hole, and the insertion post 231 is a cylinder. Of course, it can also be other shapes, such as a rectangular hole and a rectangular post.

[0069] In the preferred embodiment of the air conditioner louver device described above, the multiple louver blades 201 have the same structure. Each louver blade 201 generally includes a blade 204, a louver base 205, and a connecting portion 206. The louver base 205 and the connecting portion 206 are integrally formed on the edge of the blade 204. Each louver blade 201 can be driven by the connecting portion 206.

[0070] Specifically, the blade base 205 is integrally formed on the rear part of the lower edge of the blade 204, and the connecting part 206 is integrally formed on the middle part of the lower edge of the blade 204.

[0071] Optionally, the blade 204 is generally rectangular with rounded corners and multiple through slots (not marked in the figure) to reduce resistance and improve airflow.

[0072] Referring to Figure 3, in the preferred embodiment of the air conditioner louver device described above, the louver base 205 generally includes a column 207 and a sliding engagement structure 208. The upper end of the column 207 is integrally formed on the edge of the blade 204, and the lower end of the column 207 has a louver insertion hole 230. The sliding engagement structure 208 is integrally formed on the column 207 and is used for sliding engagement with the engagement portion 213 of the fixing mechanism 202.

[0073] It should be noted that the present invention does not impose any restrictions on the specific dimensions of the column 207, and those skilled in the art can set them according to the actual situation.

[0074] Referring to Figure 3, in the preferred embodiment of the louver device for an air conditioner described above, the sliding engagement structure 208 generally includes a protrusion 209, a first gap 210, a convex ring 211, a first notch, a second notch, and a protrusion 214. The protrusion 209 is integrally formed on the upper part of the column 207, the convex ring 211 is formed in the middle of the column 207, the first gap 210 is located between the protrusion 209 and the convex ring 211, the first notch is formed on one side of the convex ring 211, and the second notch is formed on the other side of the convex ring 211 and symmetrically arranged with the first notch. The protrusion 214 is formed on the lower side of the column 207 and is located below the convex ring 211. By providing the protrusion 209, the first gap 210, the convex ring 211, the first notch, the second notch, and the protrusion 214, it is used to engage with the engagement part 213 and is rotatable.

[0075] Specifically, the protrusion 209 is arranged in a way that semi-encloses the upper rear side of the column 207, and the top surface of the protrusion 209 forms a slope shape from back to front. The protrusion ring 211 is circular, and the protrusion 214 is a rectangular block. The protrusion 214 is used to rotate the oscillating blade 201 to the left, and when it rotates to 60°, it serves as the zero point, which facilitates the stepper motor to find the zero position.

[0076] Referring to Figures 1 and 4, in the preferred embodiment of the air conditioner louver device described above, the fixing mechanism 202 generally includes a fixing plate 228, a cover plate 212, and multiple snap-fit ​​parts 213. The fixing plate 228 is installed inside the housing 103, multiple insertion posts 231 are constructed on the top of the fixing plate 228, the cover plate 212 is fastened to the fixing plate 228, and the multiple snap-fit ​​parts 213 are constructed on the cover plate 212, corresponding one-to-one with the multiple louvers 201. The multiple snap-fit ​​parts 213 are provided for connection and engagement with the sliding snap-fit ​​structure 208.

[0077] In this embodiment, the fixing plate 228 is installed on the air outlet duct of the housing 103 by screws, and the length of the fixing plate 228 is determined according to actual needs.

[0078] Referring to Figure 4, in the preferred embodiment of the air conditioner louver device described above, the multiple locking portions 213 have the same structure. Each locking portion 213 generally includes a recessed groove 215, a first through hole 216, a sliding groove 217, a second gap, a third gap, a first baffle 220, and a second baffle 221. Specifically: The recessed groove 215 is formed on the cover plate 212, allowing the protruding ring 211 to abut against the top surface of the recessed groove 215. The first through hole 216 is formed in the middle of the recessed groove 215 to allow the lower end of the column 207 to be inserted. The sliding groove 217 is constructed on one side of the top surface of the recessed groove 215, allowing the protrusion 214 to be inserted into the sliding groove 217. The first baffle 220 is constructed on one side wall of the recessed groove 215 and has a second gap between it and the top surface of the recessed groove 215, allowing one side of the protruding ring 211 to be inserted, thus restricting the protruding ring 211. The second baffle 221 is constructed on the other side wall of the sinking groove 215 and corresponds to the first baffle 220. There is a third gap between the second baffle 221 and the top surface of the sinking groove 215 so that the other side of the protruding ring 211 can be inserted to restrict the protruding ring 211.

[0079] Specifically, the recessed groove 215 is circular, and the size of the first through hole 216 is adapted to the size of the lower end of the column 207. The slide groove 217 is arc-shaped, and its depth is greater than the height of the protrusion 214 so that the protrusion 214 can slide along the slide groove 217 when the column 207 rotates.

[0080] Referring to Figures 3 and 5, in the preferred embodiment of the air conditioner louver device described above, the connecting portion 206 generally includes a third baffle 222, a connecting post 223, and a plug 224. The third baffle 222 is integrally formed on the edge of the blade 204, the upper end of the connecting post 223 is integrally formed in the middle of the third baffle 222, and the lower end of the connecting post 223 and the plug 224 are integrally formed. The third baffle 222, connecting post 223, and plug 224 are provided for connection with the connecting rod 226 of the transmission mechanism 203.

[0081] In this embodiment, the third baffle 222 is circular, and the plug 224 is conical.

[0082] Referring to Figures 2 and 5, in the preferred embodiment of the air conditioner louver device described above, the transmission mechanism 203 includes a motor 225 and a connecting rod 226. The connecting rod 226 has third through holes 227 corresponding to the louvers 201, allowing the connecting post 223 to be inserted into the third through holes 227 and abut against the plug 224. The motor 225 is mounted to one end of the fixing mechanism 202 by screws and connected to one of the multiple louvers 201, driving one of the louvers 201 to drive the connecting rod 226, causing the other louvers 201 to rotate. The motor 225 and the control device 104 are communicatively connected via a connecting cable to control the operation of the motor 225.

[0083] As one possible implementation, the louver device 200 also includes a temperature sensor 218, which is mounted on the fixing plate 228, typically using screws. The temperature sensor 218 is communicatively connected to the control device 104, typically via a connecting cable, to obtain the air outlet temperature value of the air conditioner 100, and to determine whether the air outlet temperature of the air conditioner 100 is abnormal based on the air outlet temperature value.

[0084] Specifically, for example, when air conditioner 100 is turned on in cooling mode, it draws in indoor air, cools it through the condenser, and then returns it to the room. At this time, the air supply temperature of air conditioner 100 is usually lower than the set 25°C, generally between 14°C and 16°C. When the temperature obtained by the first temperature sensor 218 is 12°C and remains at 12°C, it is determined that the air supply temperature of air conditioner 100 is abnormal. The control device 104 sends a prompt message to the remote control so that the user can check the cause of the abnormal air supply temperature, facilitating customer repair or filter cleaning, and improving the user experience.

[0085] As one possible implementation, the louver device 200 also includes a camera 219, which is mounted on the housing 103, typically embedded and fixed with screws, and is used to detect whether there are users near the air conditioner 100. The camera 219 is communicatively connected to the control device 104, typically via a connecting cable, so as to adjust the airflow direction according to the location of the person.

[0086] Specifically, the camera 219 detects whether there is a user near the air conditioner 100. When a user is near the air conditioner 100, the camera determines the user's position. The control device 104 controls the motor 225 to work based on the user's position. The motor 225 drives the connecting rod 226 to rotate multiple swing blades 201 to the opposite position to the user's position, thus avoiding direct airflow onto the user.

[0087] In a second aspect, the present invention provides an air conditioner, the air conditioner 100 including the louver device for air conditioning as described in the first aspect. The air conditioner 100 of this technical solution includes the louver device 200 for air conditioning as described in any technical solution of the present invention, and therefore has all the technical effects of the louver device for air conditioning of any technical solution of the present invention.
