[0052] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0053] Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0054] Reference Figure 1-Figure 5 An air conditioner according to an embodiment of the present invention includes a housing 10, a heat exchanger assembly 20, an air duct assembly 21, an air outlet frame assembly 30, and a negative ion generator 60. The housing 10 is formed with an air inlet 13 and an air outlet 14. The heat exchanger assembly 20 and the air duct assembly 21 are disposed within the housing 10. During operation of the air conditioner, air outside the air conditioner enters the interior of the air conditioner through the air inlet 13 of the housing 10, undergoes heat exchange processing in the heat exchanger assembly 20, and flows out through the air outlet 14 of the housing 10. After the outflowing air has been heat exchanged in the heat exchanger assembly 20, it has the function of regulating the air temperature, thereby realizing the cooling or heating function of the air conditioner.

[0055] The air outlet frame assembly 30 includes an air outlet frame 31 and an air guide assembly 50. The air outlet frame 31 is arranged in the casing 10 and has an air outlet channel 32 connected to the air outlet 14. The air guide assembly 50 is arranged in the air outlet channel 32 and includes a rotatable air guide plate 51. The air outlet frame 31 is provided with an axis support seat 33, and the axis support seat 33 is located in the air outlet channel 32. The air guide plate 51 is provided with a rotating shaft 58. The rotating shaft 58 of the air guide plate 51 is passed through the axis support seat 33 and the rotating shaft 58 of the air guide plate 51 is rotatable relative to the axis support seat 33, so that the air guide plate 51 is rotatable relative to the air outlet frame 31 and the axis support seat 33. Air entering the air conditioner undergoes heat exchange processing in the heat exchanger assembly 20, then flows through the outlet duct 32 of the air outlet frame 31 and out of the air outlet 14 of the housing 10. A rotatable air guide plate 51 is provided within the air outlet duct 32. This air guide plate 51 can adjust the direction of the airflow from the air outlet 14, enabling the air conditioner to deliver air at multiple angles, thereby improving the air conditioning effect. Furthermore, by providing an axis support 33 on the air outlet frame 31 and a rotating shaft 58 on the air guide plate 51, which extends through the axis support 33 and is rotatable relative to the axis support 33, the stability and smoothness of the air guide plate 51 during rotation can be improved.

[0056] Optionally, the shaft support seat 33 can be integrally formed with the air outlet frame 31 to simplify the assembly process and reduce the difficulty of assembly.

[0057] The negative ion generator 60 is disposed within the housing 10 and includes a negative ion emitter head 61. The negative ion emitter head 61 is mounted on the shaft support seat 33. The shaft support seat 33 is located within the air outlet duct 32 connected to the air outlet 14. Since the negative ion emitter head 61 is mounted on the shaft support seat 33, the negative ion emitter head 61 is located within the air outlet duct 32. The negative ions emitted by the negative ion emitter head 61 can be blown out with the airflow in the air outlet duct 32 and diffused into the room, thereby enhancing the sterilization and purification effects of the negative ion generator 60. In addition, the negative ion emitter head 61 is mounted on the shaft support seat 33, and the rotating shaft 58 of the air guide plate 51 is disposed through the shaft support seat 33 and is rotatable relative to the shaft support seat 33, thereby preventing the air guide plate 51 from interfering with the negative ion emitter head 61 during movement.

[0058] According to the air conditioner of the embodiment of the present invention, the air outlet frame 31 of the air conditioner is provided with a shaft support seat 33, and the air guide plate 51 of the air conditioner is provided with a rotating shaft 58, which is provided through the shaft support seat 33 and is rotatable relative to the shaft support seat 33. The negative ion emission head 61 of the air conditioner is installed on the shaft support seat 33, which can prevent the air guide plate 51 from interfering with the negative ion emission head 61 during movement. In addition, the negative ion emission head 61 is installed on the shaft support seat 33, and the shaft support seat 33 is located in the air outlet channel 32 connected to the air outlet 14. The negative ions emitted by the negative ion emission head 61 can be blown out with the air flow in the air outlet channel 32 and diffused into the room, thereby enhancing the sterilization and purification effect of the negative ion generator 60.

[0059] Reference Figure 7-10 According to some embodiments of the present invention, the negative ion emitter head 61 is located in the middle of the air outlet channel 32 in the width direction of the air outlet 14. The negative ion emitter head 61 is located in the middle of the air outlet channel 32, so that the negative ion emitter head 61 is far away from both ends of the air outlet channel 32 in the width direction of the air outlet 14. This can reduce or prevent the negative ions emitted by the negative ion emitter head 61 from being adsorbed by the air outlet frame 31 and other components disposed in the air outlet channel 32, such as the air guide plate 51, so that the negative ions emitted by the negative ion emitter head 61 can be blown out of the air outlet 14 more smoothly and diffuse into the room.

[0060] Reference Figure 7-10 According to some embodiments of the present invention, the rotation axis of the air guide plate 51 extends along a first direction (for example, the first direction can be referred to as the up-down direction in the accompanying drawings), the air outlet 14 and the air outlet channel 32 both extend along the first direction, and the negative ion emitter 61 is adjacent to one end of the air outlet channel 32 along the first direction and faces the other end of the air outlet channel 32 along the first direction. The rotation axis of the air guide plate 51, the air outlet 14, and the air outlet channel 32 all extend along the first direction, allowing the air guide plate 51 to better adjust the direction of the airflow blown out from the air outlet 14, thereby improving the air conditioning effect of the air conditioner. The negative ion emitter head 61 is adjacent to one end of the air outlet channel 32 along the first direction and faces the other end of the air outlet channel 32 along the first direction. The negative ions emitted by the negative ion emitter head 61 can be emitted along one end of the first direction to the other end of the air outlet channel 32 along the first direction, and can be blown out from the air outlet 14 along the air flow in the air outlet channel 32 and diffuse into the room, so that the negative ions emitted by the negative ion emitter head 61 have a larger diffusion range and a wider radiation range, thereby improving the sterilization and purification effect of the negative ion generator 60.

[0061] Reference Figure 7-10According to some embodiments of the present invention, the first direction is the up-down direction, and the negative ion emission head 61 is disposed adjacent to the upper end of the air outlet channel 32 and facing downward. During operation of the negative ion generator 60, the negative ions emitted by the negative ion emission head 61 can be emitted from the upper end of the air outlet channel 32 to the lower end of the air outlet channel 32, and can be blown out from the air outlet 14 along with the air flow in the air outlet channel 32 and diffuse into the room. This allows the negative ions emitted by the negative ion emission head 61 to have a larger diffusion range and a wider radiation range, thereby enhancing the sterilization and purification effects of the negative ion generator 60.

[0062] Reference Figure 11-13 According to some embodiments of the present invention, a mounting hole 34 is provided on the shaft support base 33, and the mounting hole 34 passes through the shaft support base 33 along the first direction. The negative ion emitter 61 is mounted in the mounting hole 34. The mounting hole 34 passes through the shaft support base 33 along the first direction, so that the negative ion emitter 61 can be positioned adjacent to one end of the air outlet channel 32 along the first direction and toward the other end of the air outlet channel 32 along the first direction. This has a relatively simple structure and is relatively easy to install.

[0063] Reference Figure 11-13 According to some embodiments of the present invention, a wiring groove 35 is formed on the shaft support base 33. The negative ion output wiring harness 62 connected to the negative ion emission head 61 is adapted to be routed along the wiring groove 35. The mounting hole 34 is formed on the bottom wall of the wiring groove 35. By providing the wiring groove 35 on the shaft support base 33, the negative ion output wiring harness 62 connected to the negative ion emission head 61 is routed along the wiring groove 35. This facilitates the layout of the negative ion output wiring harness 62 and reduces or avoids the occurrence of excessively cluttered layout of the negative ion output wiring harness 62. Furthermore, the wiring groove 35 also provides protection for the negative ion output wiring harness 62.

[0064] Reference Figure 12-13 According to some embodiments of the present invention, a wiring limit buckle 351 is provided on the side wall of the wiring groove 35. The wiring limit buckle 351 is opposite to and spaced from the bottom wall of the wiring groove 35 to limit the position of the negative ion output harness 62. The wiring groove 35 is formed on the shaft support seat 33. The negative ion output harness 62 is routed along the wiring groove 35. The negative ion emission head 61 is mounted in the mounting hole 34 formed on the bottom wall of the wiring groove 35. The wiring limit buckle 351 is provided on the side wall of the wiring groove 35 to limit the negative ion output harness 62, thereby ensuring the stability and reliability of the installation of the negative ion generator 60.

[0065] Optionally, there may be multiple routing limit buckles 351 , and the multiple routing limit buckles 351 may be arranged at intervals along the extension direction of the routing groove 35 . The multiple routing limit buckles 351 may better limit the negative ion output harness 62 .

[0066] It should be noted that the term “plurality” in the present invention refers to two or more.

[0067] Reference Figure 14 According to some embodiments of the present invention, the shaft support seat 33 is further covered with a support seat cover 40, which is arranged on the side of the shaft support seat 33 where the wiring groove 35 is provided, and the support seat cover 40 is detachably connected to the shaft support seat 33. By providing the support seat cover 40, which is arranged on the side of the shaft support seat 33 where the wiring groove 35 is provided, the support seat cover 40 can protect the wiring groove 35 and the negative ion output harness 62 that runs along the wiring groove 35. In addition, the support seat cover 40 is detachably connected to the shaft support seat 33, and the connection method is relatively flexible, which can facilitate maintenance, repair, and other operations on the negative ion emission head 61 and the negative ion output harness 62.

[0068] Reference Figure 13-14 According to some embodiments of the present invention, the support seat cover 40 is connected to the shaft support seat 33 by fasteners, a positioning column 36 is formed on the shaft support seat 33, and a positioning hole 41 that cooperates with the positioning column 36 is formed on the support seat cover 40. The support seat cover 40 is connected to the shaft support seat 33 by fasteners. The connection method is relatively simple and can make the connection between the support seat cover 40 and the shaft support seat 33 more stable, and can also facilitate the disassembly of the support seat cover 40. For example, a first connecting column 37 is provided on the shaft support seat 33, and a first connecting hole 43 corresponding to the first connecting column 37 is provided at a corresponding position of the support seat cover 40. Fasteners are respectively inserted into the first connecting column 37 of the shaft support seat 33 and the first connecting hole 43 of the support seat cover 40, which can complete the connection between the support seat cover 40 and the shaft support seat 33. The connection method is relatively simple and the connection is relatively stable.

[0069] By setting a positioning column 36 on the shaft support seat 33 and a positioning hole 41 on the support seat cover 40, the positioning column 36 cooperates with the positioning hole 41 to play a positioning role during the connection process of the support seat cover 40 and the shaft support seat 33, so that the connection between the support seat cover 40 and the shaft support seat 33 is more accurate.

[0070] Reference Figure 13-14According to some embodiments of the present invention, a limiting rib 38 is formed on the side of the shaft support seat 33 close to the air outlet 14, and the support seat cover 40 is located on the side of the limiting rib 38 away from the air outlet 14 and abuts against the limiting rib 38. By providing the limiting rib 38 on the side of the shaft support seat 33 close to the air outlet 14, and the support seat cover 40 is located on the side of the limiting rib 38 away from the air outlet 14 and abuts against the limiting rib 38, during the installation process of the support seat cover 40, the support seat cover 40 abuts against the limiting rib 38, and the limiting rib 38 can play a limiting role, which can make the installation of the support seat cover 40 more accurate. In addition, the support seat cover 40 is located on the side of the limiting rib 38 away from the air outlet 14 and abuts against the limiting rib 38, which makes the structure more compact and can effectively utilize space.

[0071] Reference Figure 13 According to some embodiments of the present invention, a guide rib 352 is provided at the entrance end of the wiring trough 35.

[0072] Reference Figure 13-14 According to some embodiments of the present invention, the shaft support seat 33 is further covered with a support seat cover 40. The support seat cover 40 is provided on the side of the shaft support seat 33 where the wiring groove 35 is provided. The shaft support seat 33 is formed with an avoidance groove 42 for avoiding the guide rib 352. By providing the support seat cover 40, which is provided on the side of the shaft support seat 33 where the wiring groove 35 is provided, the support seat cover 40 can protect the wiring groove 35 and the negative ion output bundle 62 running along the wiring groove 35. In addition, the avoidance groove 42 formed on the shaft support seat 33 for avoiding the guide rib 352 can prevent the support seat cover 40 from interfering with the guide rib 352 during installation.

[0073] Reference Figure 7-Figure 8According to some embodiments of the present invention, the air guide assembly 50 includes a plurality of air guide louvers 53 arranged along a first direction, and each air guide louver 53 may be rotatable. For example, the rotation axis of the air guide louver 53 may extend in the width direction of the air outlet 14. The shaft support seat 33 is located between two adjacent air guide louvers 53. The air guide louver 53 adjacent to the negative ion emitter 61 and facing opposite to the negative ion emitter 61 is an opposing air guide louver 54. The distance between the negative ion emitter 61 and the opposing air guide louver 54 is greater than 20 mm. By providing a plurality of air guide louvers 53 arranged along the first direction, the air guide louvers 53 can guide the airflow blown out by the air outlet channel 32, thereby realizing the multi-angle air supply function of the air conditioner, thereby improving the temperature regulation effect of the air conditioner. The shaft support seat 33 is located between two adjacent air guide louvers 53, which can make full use of the space between the two air guide louvers 53 and improve space utilization. The distance between the negative ion emission head 61 and the opposite air guide louver 54 is greater than 20 mm, which can reduce the distance between the negative ion emission head 61 and the opposite air guide louver 54, resulting in the negative ions emitted by the negative ion emission head 61 being adsorbed by the opposite air guide louver 54, thereby ensuring the sterilization and purification effect of the negative ion generator 60.

[0074] Reference Figure 7-Figure 8 According to some embodiments of the present invention, when the opposing air guide louvers 54 are in a state perpendicular to the first direction, the distance L between the negative ion emission head 61 and the opposing air guide louvers 54 (refer to Figure 8 ) is greater than 50mm. When the opposing air guide louver 54 is swung to the maximum limit position in the direction close to the negative ion emission head 61, the spacing between the negative ion emission head 61 and the opposing air guide louver 54 is greater than 20mm, so that there is a certain safety distance between the negative ion emission head 61 and the opposing air guide louver 54, which can avoid the interference of the opposing air guide louver 54 with the negative ion emission head 61 when swinging in the direction close to the negative ion emission head 61.
