For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0071] Reference below Figure 1-Figure 38 The air conditioner indoor unit 100 according to an embodiment of the present invention is described. The air conditioner includes the air conditioner indoor unit 100 and the air conditioner outdoor unit. The air conditioner indoor unit 100 and the air conditioner outdoor unit cooperate to achieve heating and cooling of the air conditioner. The air conditioner indoor unit 100 can be set to be a wall unit.

[0072] like Figure 1-Figure 38As shown, an air conditioning indoor unit 100 according to an embodiment of the present invention includes: a face frame 10, a front panel 20, and a first drive device 30. The face frame 10 is provided with an air outlet 11, which is located at the bottom of the face frame 10. The air conditioning indoor unit 100 supplies air into the room through the air outlet 11. The face frame 10 is provided with a first air inlet 12, which is located at the front side of the face frame 10. When the air conditioning indoor unit 100 is turned on, air outside the air conditioning indoor unit 100 can flow into the interior of the air conditioning indoor unit 100 through the first air inlet 12. The front panel 20 is movably disposed on the face frame 10. The front panel 20 can be disposed on the front side of the face frame 10. The front panel 20 can open or close the first air inlet 12. When the front panel 20 closes the first air inlet 12, the face frame 10 and the front panel 20 together form the exterior of the air conditioning indoor unit 100. In this case, the first air inlet 12 is not visible, making the air conditioning indoor unit 100 more neat and integrated. When the air conditioner is in operation, the front panel 20 is controlled to move to open the first air inlet 12, allowing air outside the air conditioning indoor unit 100 to flow into the interior of the air conditioning indoor unit 100 through the first air inlet 12. A first drive device 30 is disposed on the face frame 10, and the front panel 20 is connected to the first drive device 30. The first drive device 30 can drive the front panel 20 to move relative to the face frame 10, thereby opening or closing the first air inlet 12.

[0073] Among them, an air guide plate 14 can be provided at the air outlet 11, and the air guide plate 14 can be rotatably set at the air outlet 11, and the air guide plate 14 can open or close the air outlet 11. When the air conditioner is on standby, that is, when the air-conditioning indoor unit 100 is not turned on, the first driving device 30 drives the front panel 20 to close the first air inlet 12. At this time, the air guide plate 14 closes the air outlet 11, and the appearance of the air-conditioning indoor unit 100 is in a fully enclosed state, which can make the appearance of the air-conditioning indoor unit 100 more neat and integrated, and can also prevent dust and other objects in the indoor environment from falling into the air-conditioning indoor unit 100 from the first air inlet 12, and can also prevent dust and other objects in the indoor environment from entering the air-conditioning indoor unit 100 from the air outlet 11, can prevent the interior of the air-conditioning indoor unit 100 from being dirty and blocked, and prevent the air-conditioning indoor unit 100 from malfunctioning due to blockage, thereby ensuring the performance of the air-conditioning indoor unit 100 and ensuring the cleanliness of the interior of the air-conditioning indoor unit 100.

[0074] Further, if Figure 2 As shown, when the air conditioner is running, the air conditioner indoor unit 100 is turned on, the first driving device 30 drives the front panel 20 to move to open the first air inlet 12, and the air guide plate 14 rotates to open the air outlet 11. The gas in the indoor environment flows into the air conditioner indoor unit 100 from the first air inlet 12, and the gas flowing into the air conditioner indoor unit 100 is blown out from the air outlet 11 after heat exchange inside the air conditioner indoor unit 100.

[0075] Therefore, the first air inlet 12 is opened or closed by the front panel 20. When the air-conditioning indoor unit 100 is not turned on, the front panel 20 is controlled to close the first air inlet 12, which can prevent dust and other objects in the indoor environment from falling into the air-conditioning indoor unit 100 through the first air inlet 12, and prevent the air-conditioning indoor unit 100 from being dirty and blocked, thereby ensuring the performance of the air-conditioning indoor unit 100, and also making the appearance of the air-conditioning indoor unit 100 closed, making the air-conditioning indoor unit 100 more neat and integrated.

[0076] In some embodiments of the present invention, Figure 4 As shown, the air conditioner indoor unit 100 has a cooling mode. When the air conditioner indoor unit 100 turns on the cooling mode, the first driving device 30 is configured to drive the front panel 20 to move below the air outlet 11, and the rear surface of the front panel 20 forms a first air guide surface 21. However, due to the high density of the cold air, the cold air inside the air conditioner indoor unit 100 will flow downward quickly after being blown out of the air outlet 11, which will cause the air supply distance of the air conditioner indoor unit 100 to be short, resulting in poor temperature drop uniformity in the indoor environment. Figure 4 As shown, in the present application, when the air-conditioning indoor unit 100 turns on the cooling mode, the first driving device 30 drives the front panel 20 to move to the bottom of the air outlet 11. At this time, the air guide plate 14 opens the air outlet 11, and the rear end of the front panel 20 can be overlapped with the lower surface of the front end of the air guide plate 14. The inner surface of the front panel 20 is the first air guide surface 21. In the direction from the rear end to the front end of the air-conditioning indoor unit 100, the front panel 20 is inclined and extended upward. After the cold air inside the air-conditioning indoor unit 100 is blown out from the air outlet 11, under the action of the first air guide surface 21, the cold air can be blown upward and / or obliquely upward, which can increase the air supply distance of the air-conditioning indoor unit 100, thereby improving the uniformity of temperature drop in the indoor environment.

[0077] Further, if Figure 5 As shown, the air conditioner indoor unit 100 has a heating mode. When the air conditioner indoor unit 100 is in heating mode, the first driving device 30 is configured to drive the front panel 20 to move in front of the air outlet 11, and the rear surface of the front panel 20 forms a second air guide surface 22. However, due to the low density of hot air, the hot air inside the air conditioner indoor unit 100 tends to rise after being blown out of the air outlet 11, resulting in a lower temperature in the area close to the ground during user use, affecting the user's comfort. Figure 5As shown, in the present application, when the air-conditioning indoor unit 100 turns on the heating mode, the first driving device 30 drives the front panel 20 to move to the front of the air outlet 11. At this time, the air guide plate 14 opens the air outlet 11, and the front panel 20 is extended in the height direction of the air-conditioning indoor unit 100. The front panel 20 is spaced apart from the front end of the air guide plate 14, and the rear surface of the front panel 20 is the second air guide surface 22. After the hot air inside the air-conditioning indoor unit 100 is blown out from the air outlet 11, under the action of the second air guide surface 22, the hot air can be guided and blown toward the bottom of the air-conditioning indoor unit 100, and a hot air wall-adhering flow air supply mode can be realized, thereby increasing the temperature of the area close to the ground and improving the user's comfort. In addition, when the air-conditioning indoor unit 100 turns on the cooling mode, the first driving device 30 drives the front panel 20 to move in front of the air outlet 11. At this time, the air guide plate 14 opens the air outlet 11, and the front panel 20 is extended in the height direction of the air-conditioning indoor unit 100. The front panel 20 is spaced apart from the front end of the air guide plate 14, and the rear surface of the front panel 20 is the second air guide surface 22. After the cold air inside the air-conditioning indoor unit 100 is blown out from the air outlet 11, the air-conditioning indoor unit 100 can achieve a windless air supply effect, thereby realizing a variety of air supply modes of the air-conditioning indoor unit 100 and improving user comfort.

[0078] In some embodiments of the present invention, Figure 6 As shown, the first drive device 30 may include a first swing arm 31, a first driving member 32, a second swing arm 33, and a second driving member 34. The first end of the first swing arm 31 is disposed on the face frame 10 and is rotatably connected to the face frame 10. The first swing arm 31 is connected to the first driving member 32, which can be configured as a stepping motor and can drive the first end of the first swing arm 31 to rotate relative to the face frame 10. The second swing arm 33 has two ends rotatably connected to the front panel 20 and the second end of the first swing arm 31, respectively. It should be noted that one end of the second swing arm 33 can be rotatably connected to the front panel 20, or one end of the second swing arm 33 can be fixedly connected to the front panel 20, and the other end of the second swing arm 33 can be rotatably connected to the second end of the first swing arm 31. The second swing arm 33 is connected to the second driving member 34, which can be configured as a stepping motor and can drive the second swing arm 33 to rotate relative to the first swing arm 31. Among them, the front panel 20 can be installed on the end of the second swing arm 33 away from the first swing arm 31 by screws or bolts, but the present invention is not limited to this. The front panel 20 can also be installed on the end of the second swing arm 33 away from the first swing arm 31 by clipping.

[0079] Furthermore, the first swing arm 31 and the second swing arm 33 can be connected via a second drive 34, allowing the second swing arm 33 to perform circular motion around the center of the connection between the second swing arm 33 and the first swing arm 31. The first swing arm 31 and the face frame 10 can be connected via a first drive 32, allowing the first swing arm 31 to perform circular motion around the center of the connection between the first swing arm 31 and the face frame 10. By cooperating with the first drive 32 and the second drive 34 to adjust the angle between the first swing arm 31 and the second swing arm 33, the position of the front panel 20 relative to the air outlet 11 and the angle between the front panel 20 and the air outlet 11 can be controlled. This allows the front panel 20 to serve as an air guide structure for the air conditioner indoor unit 100, enabling the air conditioner indoor unit 100 to have multiple different air supply modes, thereby increasing the user comfort of the air conditioner indoor unit 100.

[0080] In some embodiments of the present invention, Figure 7 As shown, a windshield strip 35 may be provided at the bottom of the front panel 20. When the first driving device 30 drives the front panel 20 to open the first air inlet 12 and the front panel 20 is located above the air outlet 11, the windshield strip 35 abuts against the face frame 10. Furthermore, the windshield strip 35 may be provided on the rear surface of the bottom of the front panel 20. When the front panel 20 opens the first air inlet 12 and the lower end of the front panel 20 is located above the air outlet 11, the windshield strip 35 abuts against the front surface of the face frame 10. Among them, when the air conditioner is working in cooling mode, the air outlet 11 blows cold air toward the room. At this time, the air outlet temperature of the air outlet 11 is low, and the indoor temperature is lower than the air outlet temperature of the air outlet 11. When the indoor gas flows into the air conditioner indoor unit 100 from the first air inlet 12, condensation is easily caused at the first air inlet 12 due to uneven temperature. Therefore, by arranging a wind shield 35 on the rear surface of the bottom of the front panel 20, when the wind shield 35 stops on the front surface of the face frame 10, the return air heat exchange at the air outlet 11 can be isolated, thereby avoiding the formation of condensation at the first air inlet 12 due to uneven temperature.

[0081] Furthermore, the windshield strip 35 can be set as a silicone strip, the windshield strip 35 can be set as a brush, or the windshield strip 35 can be set as a sponge. The specific type of windshield strip 35 can be selected according to actual needs. Such a setting can simplify the structure of the windshield strip 35, facilitate the production and manufacturing of the windshield strip 35, thereby improving the production efficiency of the windshield strip 35, and can also reduce the production cost of the windshield strip 35.

[0082] In some embodiments of the present invention, Figure 8As shown, the face frame 10 may be provided with a second air inlet 13, which may be provided on the top wall of the face frame 10. Air outside the air conditioning indoor unit 100 may flow into the interior of the air conditioning indoor unit 100 through the second air inlet 13. The air conditioning indoor unit 100 may further include: a first purification component 40, which is provided corresponding to the second air inlet 13. The first purification component 40 may be provided directly below the second air inlet 13. In the height direction of the air conditioning indoor unit 100, the first purification component 40 covers the second air inlet 13. An air inlet grille may be provided at the second air inlet 13. The first purification component 40 may be provided as a purification net with a purification function. When the first driving device 30 drives the front panel 20 to close the first air inlet 12, indoor air flows into the interior of the air conditioning indoor unit 100 from the second air inlet 13. After passing through the first purification component 40, the air is blown out from the air outlet 11. The first purification component 40 can be equipped with different types of filters based on user needs. For example, if the user needs to remove formaldehyde, the first purification component 40 can be equipped with a manganese filter for formaldehyde removal. If the user needs to remove particulate matter, dust, and odor, the first purification component 40 can be equipped with a HEPA (High Efficiency Particulate Air Filter) filter and / or a carbon-coated HEPA filter. If the user needs sterilization, the first purification component 40 can be equipped with a plasma filter. This configuration can provide the air conditioning indoor unit 100 with a purification function.

[0083] In some embodiments of the present invention, Figure 9 As shown, when the first driving device 30 drives the front panel 20 to open the first air inlet 12, the air-conditioning indoor unit 100 exposes the first air inlet 12 in front. Because the first purification component 40 is arranged at the second air inlet 13, the indoor gas will preferentially enter the interior of the air-conditioning indoor unit 100 from the first air inlet 12 with low wind resistance. At this time, the air conditioner can achieve the cooling or heating function with maximum efficiency.

[0084] In some embodiments of the present invention, Figure 10As shown, the air conditioning indoor unit 100 may further include a second purification assembly 50, which may be mounted on the front frame 10. The air conditioning indoor unit 100 has a first operating state. When the air conditioning indoor unit 100 is in the first operating state, the first driving device 30 drives the front panel 20 to open the first air inlet 12, and the second purification assembly 50 is positioned at the first air inlet 12 to purify the air. The first operating state may be a purification mode or a low-demand cooling / heating mode. By cooperating with the first and second driving members 32 and 34 to adjust the angle between the first and second swing arms 31 and 33, indoor air passes through the second purification assembly 50 and enters the interior of the air conditioning indoor unit 100. The air inside the air conditioning indoor unit 100 is then blown out of the air outlet 11, achieving a circulating purification of the indoor air. Furthermore, the second purification assembly 50 may be configured as a filter. The type of filter can be selected based on user needs. For example, a manganese filter can be used to remove formaldehyde. When users need to remove particulate matter, dust and odor, they can use HEPA filter and / or carbon HEPA. When users need sterilization, they can use plasma filter.

[0085] Further, if Figure 14 As shown, the first operating state can be when the air conditioner is in purification mode or low-demand cooling and heating mode. The front panel 20 is opened to a certain angle, and the indoor air passes through the second purification component 50 and enters the interior of the air conditioner indoor unit 100. The air inside the air conditioner indoor unit 100 is then blown out from the air outlet 11, achieving a circulating purification of the indoor air. The second purification component 50 can be configured as a manganese mesh for formaldehyde removal, an IFD purification mesh for particulate matter purification, or a high-resistance HEPA mesh. It can also be configured as a plasma-type ion generating filter for sterilization and purification.

[0086] In some embodiments of the present invention, Figure 20-24 As shown, the second purification assembly 50 may include: a mounting bracket 51 and a purification member 52. The mounting bracket 51 is retractably mounted on the face frame 10, and the purification member 52 is mounted on the mounting bracket 51. The purification member 52 is detachably mounted on the mounting bracket 51. The purification member 52 may be configured as a filter. When the purification member 52 needs to be replaced, the mounting bracket 51 can be pulled out from the face frame 10 and then the purification member 52 can be removed from the mounting bracket 51. This arrangement facilitates the replacement or removal of the purification member 52, achieving the technical effect of the replaceable purification member 52.

[0087] In some embodiments of the present invention, Figures 20-33As shown, the air conditioning indoor unit 100 may further include: a guide rail assembly 60, and the guide rail assembly 60 may include: a first guide rail 61 and a second guide rail 62. The first guide rail 61 may be provided on the face frame 10. The second guide rail 62 may be provided on the mounting bracket 51, and the first guide rail 61 and the second guide rail 62 may be pulled together. A disassembly positioning member 63 may be provided on the second guide rail 62, and the disassembly positioning member 63 may be slidably engaged with the first guide rail 61. A trigger hole 64 may be provided on the first guide rail 61, and a portion of the structure of the disassembly positioning member 63 may be moved to extend into the trigger hole 64. After the portion of the structure of the disassembly positioning member 63 extends into the trigger hole 64, the position of the second guide rail 62 relative to the first guide rail 61 can be positioned, as shown in FIG. Figure 30 As shown, a positioning column 65 can be provided on the disassembly positioning member 63. When the positioning column 65 moves to a position corresponding to the trigger hole 64, under the action of the elastic force of the disassembly positioning member 63 itself, the positioning column 65 extends into the trigger hole 64, and the position between the second guide rail 62 and the first guide rail 61 is fixed. The second guide rail 62 cannot be pulled out. At this time, the purification component 52 on the mounting bracket 51 can be removed and replaced, or the purification component 52 can be installed in the mounting bracket 51.

[0088] Furthermore, by pressing the disassembly positioning member 63 through the trigger hole 64, disengaging the positioning post 65 of the disassembly positioning member 63 from the trigger hole 64, the second guide rail 62 can be pulled out and separated from the first guide rail 61. When the mounting bracket 51 needs to be installed into the face frame 10, the user can press the positioning post 65 of the disassembly positioning member 63 to disengage the positioning post 65 from the trigger hole 64, and then push the second guide rail 62 into the first guide rail 61 to install the mounting bracket 51 into the face frame 10. Furthermore, when the second guide rail 62 needs to be removed from the first guide rail 61, the user can press the positioning post 65 of the disassembly positioning member 63 to disengage the positioning post 65 from the trigger hole 64, and then pull the second guide rail 62 to remove it from the first guide rail 61.

[0089] Further, if Figure 30As shown, the guide rail assembly 60 may further include: a third guide rail 66, the third guide rail 66 is connected between the first guide rail 61 and the second guide rail 62, the third guide rail 66 is pulled together with the first guide rail 61, and the third guide rail 66 is pulled together with the second guide rail 62, the first guide rail 61 is sleeved on the outside of the third guide rail 66, and the third guide rail 66 is sleeved on the outside of the second guide rail 62, the end of the third guide rail 66 that cooperates with the first guide rail 61 is provided with a disassembly positioning member 63, the disassembly positioning member 63 slides with the first guide rail 61, the end of the second guide rail 62 that cooperates with the third guide rail 66 is provided with a disassembly positioning member 63, the disassembly positioning member 63 slides with the third guide rail 66, the third guide rail 66 is provided with a trigger hole 64, and the positioning column 65 of the disassembly positioning member 63 provided on the second guide rail 62 is suitable for extending into the trigger hole 64 of the third guide rail 66. Furthermore, a sealing cover 67 is provided at the end of the second guide rail 62 away from the third guide rail 66, and the sealing cover 67 is connected to the mounting bracket 51. By pulling and coordinating the first guide rail 61, the second guide rail 62 and the third guide rail 66, the purification component 52 can be easily replaced.

[0090] Further, if Figure 25 As shown, the mounting bracket 51 may be provided with a mounting groove 55, and the mounting groove 55 may be provided in plurality. The side wall of the mounting groove 55 may be provided with a spring buckle 54, and the spring buckle 54 may be provided in plurality. Through interference fit between the plurality of spring buckles 54 and the purification component 52, the purification component 52 can be reliably installed in the mounting groove 55 of the mounting bracket 51, thereby preventing the purification component 52 from falling from the mounting bracket 51.

[0091] Further, if Figure 21 、 Figure 25 and Figure 36 As shown, the air-conditioning indoor unit 100 may further include: a pressure cover 68. After the purification component 52 is installed in the mounting groove 55 of the mounting bracket 51, the pressure cover 68 is covered to firmly mount the purification component 52 in the mounting bracket 51, and then the second guide rail 62 and the third guide rail 66 are pushed to install the mounting bracket 51 into the face frame 10. Finally, the relative positions of the first guide rail 61, the second guide rail 62 and the third guide rail 66 are fixed, and the mounting bracket 51 will not slide out of the face frame 10.

[0092] Further, if Figure 25 As shown, the inner surface of the side wall of the mounting groove 55 may be provided with a support platform 69 for supporting the pressure cover 68 . This arrangement can prevent the pressure cover 68 from excessively squeezing the purification component 52 , thereby avoiding damage to the purification component 52 .

[0093] In some embodiments of the present invention, Figure 12 and Figure 16As shown, the second purification component 50 is movable relative to the face frame 10. The air conditioning indoor unit 100 may further include: a second driving device 70, the second purification component 50 being connected to the second driving device 70, and the second driving device 70 being capable of driving the second purification component 50 to move. The air conditioning indoor unit 100 has a second operating state. In the second operating state, the first driving device 30 drives the front panel 20 to open the first air inlet 12, and the second driving device 70 drives the second purification component 50 to avoid the first air inlet 12. When the air conditioning indoor unit 100 is operating in the second operating state, the air conditioner requires a larger circulating air volume. The second driving device 70 drives the second purification component 50 to avoid the first air inlet 12, so that the indoor air can flow directly from the first air inlet 12 into the air conditioning indoor unit 100 without passing through the second purification component 50, thereby increasing the air intake volume of the air conditioning indoor unit 100 per unit time, thereby achieving a stronger blowing effect.

[0094] Further, if Figure 13 As shown, when the air-conditioning indoor unit 100 is working in the second working state, the second driving device 70 drives the second purification component 50 to avoid the first air inlet 12. The air conditioner needs to supply air over a wider area and needs to take into account the blowing comfort of users near the air outlet 11. By adjusting the position of the air guide plate 14 and the second purification component 50, a more comfortable wide-area air supply can be achieved.

[0095] In some embodiments of the present invention, Figure 16 As shown, when the air conditioner indoor unit 100 is in the second working state, the second driving device 70 drives the second purification component 50 to be attached to the rear surface of the front panel 20. Figure 16 As shown, when the air conditioner requires strong cooling or heating, the second drive device 70 drives the second purification component 50, and the first drive device 30 drives the front panel 20 to open outward at a certain angle, and the indoor circulating air directly enters the air conditioner indoor unit 100 through the opened first air inlet 12, thereby realizing low wind resistance heat exchange of the air conditioner indoor unit 100. Users can achieve rapid cooling or heating through this mode.

[0096] In some embodiments of the present invention, Figure 14-17As shown, the air-conditioning indoor unit 100 may further include: a support frame 80, a second driving device 70 connected to the support frame 80, the second driving device 70 may drive the support frame 80 to move, a disassembly port 81 may be provided below the support frame 80, and the second purification component 50 may be detachably provided in the support frame 80 through the disassembly port 81. In this embodiment, the front panel 20 may be connected to the face frame 10 through a first connecting plate 23 and a second connecting plate 24, one end of the first connecting plate 23 is connected to the front panel 20, the other end of the first connecting plate 23 is connected to the second connecting plate 24, the second connecting plate 24 is connected to the face frame 10, a guide groove 25 may be provided on the second connecting plate 24, and the other end of the first connecting plate 23 may be slidably provided in the guide groove 25. As shown Figure 17 As shown, when the user needs to replace the second purification component 50, the user pushes the front panel 20 upward, at which time the first connecting plate 23 slides upward in the guide groove 25, exposing the disassembly opening 81 below the support frame 80. The user can easily remove the second purification component 50 from the disassembly opening 81 to clean and replace the second purification component 50. In addition, when the second purification component 50 does not need to be replaced, the other end of the first connecting plate 23 is controlled to slide in the guide groove 25 so that the front panel 20 blocks the disassembly opening 81, and the second purification component 50 cannot be removed from the disassembly opening 81, thereby preventing the second purification component 50 from falling from the disassembly opening 81.

[0097] It should be noted that in Figures 14-19 In the embodiment shown, the second drive device 70 can be configured as a stepper motor to directly drive the second purification component 50. The second drive device 70 can also be configured as a gear set 73 and a third drive member. The third drive member can be configured as a stepper motor. The gear set 73 is engaged between the third drive member and the second purification component 50. By configuring the gear set 73 to drive, electronically controlled automatic opening and closing with greater torque can be achieved. Figures 14-19 In the embodiment shown, the first drive device 30 can also be set to a stepper motor to directly drive the front panel 20 to move. The first drive device 30 can also be set to a gear set 73 and a fourth drive member. The fourth drive member can be set to a stepper motor. The gear set 73 is engaged between the fourth drive member and the front panel 20. By setting the gear set 73 to drive, electronically controlled automatic opening and closing with greater torque can be achieved.

[0098] In some embodiments of the present invention, Figure 4-Figure 6 、 Figure 10-13As shown, the second purification assembly 50 is rotatably connected to the face frame 10. Specifically, the lower end of the second purification assembly 50 is rotatably connected to the face frame 10. In this embodiment, the second drive device 70 may include a motor 71 and a swing arm 72. The motor 71 is disposed on the face frame 10, and the ends of the swing arm 72 are connected to the second purification assembly 50 and the motor 71, respectively. In other words, one end of the swing arm 72 is connected to the second purification assembly 50, and the other end of the swing arm 72 is connected to the motor 71. The motor 71 can drive the swing arm 72 to rotate, and when the swing arm 72 rotates, it can drive the second purification assembly 50 to rotate relative to the face frame 10. Among them, when the motor 71 drives the rocker arm 72 to rotate, the rocker arm 72 drives the second purification component 50 to rotate around the connection between the second purification component 50 and the face frame 10, so that the second purification component 50 can be rotated to different positions. Through the cooperation of the front panel 20 and the second purification component 50, multiple operating modes of the air-conditioning indoor unit 100 are realized, solving the problem that the air volume requirement of the normal operation of the air-conditioning indoor unit 100 cannot be met when the high wind resistance second purification component 50 is configured.

[0099] In some embodiments of the present invention, Figure 12 As shown, when the air-conditioning indoor unit 100 is working in the second working state, the air conditioner requires a larger circulating air volume, the motor 71 rotates clockwise, and the motor 71 drives the swing rod 72 to swing clockwise. At this time, the second purification component 50 rotates counterclockwise outward by a certain angle, exposing the first air inlet 12, so that the cooling and heating circulating air of the air conditioner can enter the air-conditioning indoor unit 100 without passing through the second purification component 50, thereby achieving stronger cooling or heating.

[0100] In some embodiments of the present invention, Figure 6 and Figure 15 As shown, the second purification component 50 may include a plasma filter 53. The air conditioner 100 has a third operating state. When the air conditioner 100 is in the third operating state, the front panel 20 opens the first air inlet 12, the air guide plate 14 closes the air outlet 11, and the plasma filter 53 is located at the first air inlet 12. When the plasma filter 53 is located at the first air inlet 12, by closing the air outlet 11, indoor air flows into the air conditioner 100 through the plasma filter 53. The air carries active ions emitted by the plasma, which circulate within the air conditioner 100, thereby achieving sterilization and purification within the air conditioner 100, for example, sterilizing the evaporator fins and the impeller and air duct surfaces.

[0101] It should be noted that the air conditioner indoor unit 100 of the present application opens and closes through the movement of the front panel 20 and the second purification assembly 50, resulting in a fully enclosed appearance of the air conditioner indoor unit 100. This prevents dust from falling and causing internal clogging when the air conditioner indoor unit 100 is not in operation. Furthermore, through the movement of the second purification assembly 50 and the front panel 20, both the purification mode and the air conditioning function are not affected, and full power operation is possible. Through structural optimization, the removal and installation of the filter is more convenient and quick, and by utilizing the front panel 20 as an air guide mechanism, the air conditioner achieves a variety of comfortable air supply.
