[0032] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Reference below Figure 1-Figure 4 Describing an air conditioner according to an embodiment of the present invention, Figure 2-Figure 4 The direction indicated by the arrow in the middle is the direction of air flow.

[0034] refer to Figure 1-Figure 4 The air conditioner according to the embodiment of the present invention comprises: a casing 1, a heat exchange and air supply assembly 2, an air guide plate assembly 3, a first driving mechanism 4 and a second driving mechanism 5, wherein the heat exchange and air supply assembly 2 is arranged in the casing 1.

[0035] The air conditioner housing 1 is formed with an air inlet 12, an air outlet 11 and an air outlet passage 13. The air inlet 12, the air outlet 11 and the air outlet passage 13 are connected and arranged. The external airflow of the air conditioner can enter the housing 1 through the air inlet 12, and the internal airflow of the air conditioner can flow out of the housing 1 through the air outlet 11. The heat exchange air supply component 2 is located at the upstream side of the air outlet passage 13. For example, the heat exchange air supply component 2 includes a heat exchanger component 21 and a fan component. The airflow path of the air conditioner is as follows: the indoor airflow enters the air conditioner through the air inlet 12, the airflow entering the air conditioner exchanges heat with the heat exchanger component 21 to achieve cooling or heating, and then is sent to the air outlet passage 13 through the fan component. After the airflow flows through the air outlet passage 13, it is sent to the outside of the air conditioner through the air outlet 11 and enters the room.

[0036] The air guide plate assembly 3 includes a main air guide plate 31 and at least one auxiliary air guide plate 32. The main air guide plate 31 is rotatably disposed at the air outlet 11. One end of the main air guide plate 31 is rotatably connected to the housing 1. The main air guide plate 31 can open or close the air outlet 11 by rotating around one end of the main air guide plate 31 relative to the housing 1. A through hole 311 is formed on the main air guide plate 31 and penetrates the main air guide plate 31 along the thickness direction of the main air guide plate 31. The auxiliary air guide plate 32 is movably disposed at the through hole 311. The auxiliary air guide plate 32 can open or close the through hole 311 by moving relative to the main air guide plate 31.

[0037] For example, a through opening 311 is formed on the main air guide plate 31, and the air guide plate assembly 3 includes a secondary air guide plate 32, which is movably disposed at the through opening 311. For another example, a through opening 311 is formed on the main air guide plate 31, and the air guide plate assembly 3 includes a plurality of secondary air guide plates 32, and the plurality of secondary air guide plates 32 can be movably disposed at the through opening 311. For another example, a plurality of through openings 311 are formed on the main air guide plate 31, and the air guide plate assembly 3 includes a plurality of secondary air guide plates 32, the number of the secondary air guide plates 32 is the same as the number of the through openings 311 and corresponds one to one, and each secondary air guide plate 32 can be movably disposed at a corresponding through opening 311. Wherein, when the air guide plate assembly 3 includes a plurality of secondary air guide plates 32, each of the plurality of secondary air guide plates 32 can be independently controlled.

[0038] The first driving mechanism 4 is connected to the other end of the main air guide plate 31, and the first driving mechanism 4 is used to drive the other end of the main air guide plate 31 to move. The first driving mechanism 4 controls the other end of the main air guide plate 31 to move relative to the housing 1 to open or close the air outlet 11. Optionally, the first driving mechanism 4 drives the main air guide plate 31 to rotate around one end of the main air guide plate 31 and in a direction away from the housing 1 toward the other end of the main air guide plate 31 to open the air outlet 11; optionally, the first driving mechanism 4 drives the main air guide plate 31 to rotate around one end of the main air guide plate 31 and in a direction close to the housing 1 toward the other end of the main air guide plate 31 to close the air outlet 11. By connecting the first driving structure to the other end of the main air guide plate 31, when the first driving mechanism 4 drives the main air guide plate 31 to rotate, the force application position of the first driving mechanism 4 is located at the other end of the main air guide plate 31. When the main air guide plate 31 receives the force and rotates around one end of the main air guide plate 31, the one end of the main air guide plate 31 is the rotating end of the main air guide plate 31. Since the distance between the position where the force is applied and the rotating end of the main air guide plate 31 is relatively far, the torque formed by the force of the first driving mechanism 4 is relatively large. When the main air guide plate 31 needs to rotate a certain angle, the first driving mechanism 4 only needs to apply a small force to rotate the main air guide plate 31 to the required angle, which can reduce the energy consumption of the first driving mechanism 4.

[0039] The second driving mechanism 5 is used to drive the auxiliary air guide plate 32 to move. The second driving mechanism 5 controls the auxiliary air guide plate 32 to move relative to the main air guide plate 31 to open and close the opening 311 .

[0040] Among them, the air guide plate assembly 3 can open the air outlet 11 by moving the main air guide plate 31 relative to the casing 1, and the air guide plate assembly 3 can also open the opening 311 on the main air guide plate 31 by moving the auxiliary air guide plate 32 relative to the main air guide plate 31. The air guide plate assembly 3 can also simultaneously move the main air guide plate 31 relative to the casing 1 to open the air outlet 11 and move the auxiliary air guide plate 32 relative to the main air guide plate 31 to open the opening 311.

[0041] For example, when the main air guide plate 31 moves relative to the casing 1 to open the air outlet 11, the air flow in the air outlet channel 13 can be blown into the room through the air outlet 11, and the main air guide plate 31 is controlled by the first driving mechanism 4 to control the air outlet angle, air outlet range, and opening ratio of the air outlet 11, thereby adjusting the air outlet.

[0042] For another example, when the auxiliary air guide plate 32 moves relative to the main air guide plate 31 to open the opening 311 on the main air guide plate 31, the air flow in the air outlet channel 13 can be blown out to the room through the opening 311, and the auxiliary air guide plate 32 is controlled by the second driving mechanism 5 to control the air outlet angle, air outlet range, and opening ratio of the air flow blown out from the opening 311, thereby adjusting the air outlet.

[0043] For another example, when the main air guide plate 31 moves relative to the casing 1 to open the air outlet 11 and the auxiliary air guide plate 32 moves relative to the main air guide plate 31 to open the opening 311 on the main air guide plate 31, part of the airflow in the air outlet channel 13 can be blown out to the room through the air outlet 11, and another part of the airflow in the air outlet channel 13 can flow into the room through the opening 311 on the main air guide plate 31, so that the airflow in the air outlet channel 13 can flow out to the room from different outlets, and the main air guide plate 31 can be controlled by the first driving mechanism 4 and the auxiliary air guide plate 32 can be controlled by the second driving mechanism 5 to control the air volume and air outlet angle of the airflow in the air outlet channel 13 from different outlets.

[0044] Compared with a single air guide plate disposed at the air outlet 11 to adjust the air outlet, the air guide plate assembly 3 of the embodiment of the present invention has more diversified air outlet adjustments.

[0045] According to the air conditioner of the embodiment of the present invention, an air guide plate assembly 3 is provided so that the air guide plate assembly 3 includes a main air guide plate 31 and at least one auxiliary air guide plate 32. The auxiliary air guide plate 32 is rotatably provided at the opening 311 of the main air guide plate 31. The main air guide plate 31 is rotatably provided at the air outlet 11. The state of the air guide plate assembly 3 can be changed by controlling the main air guide plate 31 and the auxiliary air guide plate 32. When the air guide plate assembly 3 is in different states, different air outlet adjustment functions can be formed for the air outlet 11, thereby making the air outlet adjustment of the air guide plate assembly 3 for the air outlet 11 more diversified, so as to provide users with more choices and better meet the user's usage needs.

[0046] refer to Figure 1-Figure 4According to some embodiments of the present invention, the air outlet 11 is formed at the front of the casing 1, so that the airflow in the air conditioner can enter the room through the air outlet 11 to better regulate the indoor air. The air outlet channel 13 has a first side wall 132 and a second side wall 133 which are arranged opposite to each other along the width direction of the air outlet 11. The first side wall 132 is located at the lower side of the air outlet channel 13. The airflow in the air outlet channel 13 flows to the air outlet 11 under the guidance of the first side wall 132 and the second side wall 133. One end of the main air guide plate 31 is rotatably connected to the casing 1. The connection position of one end of the main air guide plate 31 with the casing 1 is closer to the first side wall 132 than the second side wall 133, and the other end of the main air guide plate 31 is closer to the second side wall 133 than the first side wall 132. The main air guide plate 31 opens or closes the air outlet 11 by rotating relative to the casing 1 around one end of the main air guide plate 31. Furthermore, by making the main air guide plate 31 rotatable, it is convenient to control the outlet angle, outlet range, opening ratio of the air outlet 11, etc. of the air flow at the air outlet 11 by controlling the rotation angle of the main air guide plate 31, so as to better meet the use requirements of the air conditioner. By making the connection position of one end of the main air guide plate 31 and the housing 1 closer to the first side wall 132 than the second side wall 133, when the main air guide plate 31 rotates around one end of the main air guide plate 31 to open the air outlet 11, the main air guide plate 31 guides the air flow entering the room through the air outlet 11 to flow upward in the room, which can improve the comfort of the air conditioning effect of the air conditioner, for example, it can improve the cooling comfort of the air conditioner.

[0047] refer to Figure 1-Figure 4 According to some optional embodiments of the present invention, the housing 1 includes a front panel 14, which is located on the upper side of the air outlet 11. The heat exchange and air supply assembly 2 includes a heat exchanger component 21 and an air duct assembly. For example, the air duct assembly may include a fan component, and the fan component is used to drive the airflow into the air outlet channel 13. The heat exchanger component 21 is located between the air duct assembly and the air inlet 12, and the heat exchanger component 21 is used to cool or heat the airflow entering the air conditioner through the air inlet 12. An accommodating chamber 15 is defined between the air duct assembly and the front panel 14. The first driving mechanism 4 includes a first motor 41 and a transmission mechanism 42. The first motor 41 is located in the accommodating chamber 15. The transmission mechanism 42 can drive and connect the motor shaft 411 of the first motor 41 and the other end of the main air guide plate 31. The first motor 41 is used to control the movement of the main air guide plate 31. By arranging the first motor 41 in the accommodating chamber 15, it is beneficial to reasonably utilize the space in the air conditioner and to reasonably arrange the components in the air conditioner. By setting up a transmission mechanism 42, the power output by the first motor 41 can be transmitted to the other end of the main air guide plate 31 through the transmission mechanism 42; and by enabling the transmission mechanism 42 to transmit and connect the motor shaft 411 and the other end of the main air guide plate 31, the power transmission method and structural design are simple.

[0048] refer to Figure 1-Figure 4 According to some optional embodiments of the present invention, the transmission mechanism 42 includes a transmission gear 421 and a transmission rack 422. The transmission gear 421 is arranged on the motor shaft 411 and is located in the accommodating chamber 15. The transmission rack 422 extends in the up-down direction and meshes with the transmission gear 421. The lower end of the transmission rack 422 is movably connected to the other end of the main air guide plate 31. By providing the transmission gear 421 and the transmission rack 422, the power output by the first motor 41 can be transmitted to the other end of the main air guide plate 31 through the transmission gear 421 and the transmission rack 422. This power transmission method is stable and reliable, and the movement of the main air guide plate 31 can be stably and reliably controlled by the first motor 41. By arranging the transmission gear 421 on the motor shaft 411, the design of the power transmission structure can be simplified. Through the meshing transmission of the transmission gear 421 and the transmission rack 422, the precise control of the rotation angle of the main air guide plate 31 can be achieved.

[0049] Optionally, the transmission rack 422 is partially located in the accommodating cavity 15 and the transmission rack 422 is close to the front panel 14 of the casing 1. Such an arrangement is conducive to reasonable utilization of the space inside the air conditioner.

[0050] refer to Figure 1-Figure 4 According to some optional embodiments of the present invention, a matching hole 312 extending along the width direction of the main air guide plate 31 is formed on the main air guide plate 31, and a guide column 4221 is provided at the lower end of the transmission rack 422. The guide column 4221 is penetrated through the matching hole 312 and is movable relative to the matching hole 312 along the width direction of the air guide plate. When the transmission rack 422 drives the other end of the main air guide plate 31 to move, the main air guide plate 31 will rotate around one end of the main air guide plate 31, and the guide column 4221 of the transmission rack 422 will move relative to the matching hole 312 along the width direction of the air guide plate. For example, when the transmission rack 422 moves downward under the drive of the first motor 41 and the transmission gear 421, the transmission rack 422 drives the main air guide plate 31 to rotate around one end of the main air guide plate 31 toward the direction away from the front plate of the housing 1 to open the air outlet 11, and at this time, the guide column 4221 moves relative to the matching hole 312 along the width direction of the air guide plate toward the end close to the main air guide plate 31. For example, when the transmission rack 422 moves upward under the drive of the first motor 41 and the transmission gear 421, the transmission rack 422 drives the main air guide plate 31 to rotate around one end of the main air guide plate 31 toward the direction close to the front plate of the housing 1 to close the air outlet 11. At this time, the guide column 4221 moves relative to the matching hole 312 along the width direction of the air guide plate toward the other end close to the main air guide plate 31. By providing the matching hole 312 and the guide column 4221, and making the guide column 4221 movable relative to the matching hole 312, the main air guide plate 31 can rotate around one end of the main air guide plate 31 when the transmission rack 422 moves in the up and down direction, which can prevent the transmission rack 422 and the main air guide plate 31 from getting stuck.

[0051] According to some optional embodiments of the present invention, a evacuation hole is formed on the second side wall 133, and the transmission rack 422 is movably disposed in the evacuation hole. For example, the first driving mechanism 4 is disposed near the middle of the air conditioner in the width direction of the air conditioner, the first motor 41 and the transmission gear 421 are disposed in the accommodating chamber 15, and the transmission rack 422 is connected to the other end of the main air guide plate 31 through the evacuation hole on the second side wall 133 to control the movement of the main air guide plate 31. The transmission rack 422 is connected to the other end of the main air guide plate 31 through the evacuation hole, and when the transmission rack 422 receives the power output from the first motor 41 through the transmission gear 421, the transmission rack 422 can move in the up and down direction relative to the evacuation hole, and then the transmission rack 422 drives the main air guide plate 31 to rotate.

[0052] According to some optional embodiments of the present invention, a guide rail extending in the up-down direction is provided on the front panel 14, and the transmission rack 422 can slide with the guide rail. By providing the guide rail, under the guidance of the guide rail, the transmission rack 422 receives the power from the first motor 41 through the transmission gear 421 and slides relative to the guide rail in the up-down direction; and the guide rail can stably connect the transmission rack 422 between the transmission gear 421 and the other end of the main air guide plate 31.

[0053] refer to Figure 1-Figure 4 According to some embodiments of the present invention, the auxiliary air guide plate 32 is rotatable, and the auxiliary air guide plate 32 is rotated relative to the main air guide plate 31 to open or close the opening 311 of the main air guide plate 31. By making the auxiliary air guide plate 32 rotatable, it is convenient to control the air outlet angle, air outlet range, opening ratio of the airflow at the opening 311 by controlling the rotation angle of the auxiliary air guide plate 32, so as to better meet the use requirements of the air conditioner.

[0054] refer to Figure 1-Figure 4 According to some embodiments of the present invention, the second driving mechanism 5 is mounted on the main air guide plate 31 and connected to the auxiliary air guide plate 32. For example, the second driving mechanism 5 may include a second motor. By mounting the second driving mechanism 5 on the main air guide plate 31, when the main air guide plate 31 opens the air outlet 11 by movement, the second driving mechanism 5 and the auxiliary air guide plate 32 may move together with the main air guide plate 31, so that the structural design between the second driving mechanism 5 and the auxiliary air guide plate 32 can be simplified.

[0055] refer to Figure 1-Figure 4According to some optional embodiments of the present invention, the main air flow plate 31 includes a main air flow plate body 314 and a fixing plate 313, the fixing plate 313 is arranged on the inner side of the main air flow plate body 314, and the second driving mechanism 5 is installed on the fixing plate 313, so that the second driving mechanism 5 can be installed on the main air flow plate 31. When the main air flow plate 31 is located at a position closing the air outlet 11, the side of the main air flow plate body 314 facing the inside of the casing 1 is the inner side of the main air flow plate body 314. By making the main air flow plate 31 include the main air flow plate body 314 and the fixing plate 313, the second driving mechanism 5 can be installed on the main air flow plate 31 through the fixing plate 313, thereby improving the installation stability and reliability of the second driving mechanism 5.

The main air guide plate body 314 is formed with a through opening 311. When the auxiliary air guide plate 32 is located at a position to close the through opening 311, the auxiliary air guide plate body 321 covers the through opening 311, and the outer surface of the auxiliary air guide plate body 321 is flush with the outer surface of the main air guide plate body 314. When the main air guide plate 31 is located at a position to close the air outlet 11, the surface of the main air guide plate 31 facing the outside of the housing 1 is the outer surface of the main air guide plate 31; when the auxiliary air guide plate 32 is located at a position to close the through opening 311, the surface of the auxiliary air guide plate 32 facing the outside of the housing 1 is the outer surface of the auxiliary air guide plate 32. By arranging the outer surface of the auxiliary air guide plate body 321 flush with the outer surface of the main air guide plate body 314, the covering effect of the auxiliary air guide plate body 321 on the opening 311 can be improved. When the opening 311 is not opened, the airflow through the opening 311 is prevented from flowing toward different angles or positions, thereby reducing or avoiding the impact on the air conditioning effect of the air conditioner.

[0058] refer to Figure 1-Figure 4According to some embodiments of the present invention, the main air guide plate 31 includes a main air guide plate body 314, and the auxiliary air guide plate 32 includes an auxiliary air guide plate body 321. The main air guide plate body 314 is formed with a through opening 311. When the auxiliary air guide plate 32 is located at a position closing the through opening 311, the auxiliary air guide plate body 321 covers the through opening 311, and the inner surface of the auxiliary air guide plate body 321 is flush with the inner surface of the main air guide plate body 314. When the main air guide plate 31 is located at a position closing the air outlet 11, the side surface of the main air guide plate 31 facing the inside of the housing 1 is the inner surface of the main air guide plate 31; when the auxiliary air guide plate 32 is located at a position closing the through opening 311, the side surface of the auxiliary air guide plate 32 facing the inside of the housing 1 is the inner surface of the auxiliary air guide plate 32. By arranging the inner surface of the auxiliary air guide plate 321 flush with the inner surface of the main air guide plate 314, the covering effect of the auxiliary air guide plate 321 on the opening 311 can be improved. When the opening 311 is not opened, the airflow at the air outlet 11 is prevented from flowing toward different angles or positions through the opening 311, so as to reduce or avoid the impact on the air conditioning effect of the air conditioner.

[0059] refer to Figure 1-Figure 4 According to some embodiments of the present invention, the air guide plate assembly 3 is in different states by controlling the main air guide plate 31 and the auxiliary air guide plate 32. In different states of the air guide plate assembly 3, the air conditioner has at least one of the first working mode, the second working mode and the third working mode.

[0060] Among them, the air conditioner has at least one of the first working mode, the second working mode and the third working mode, including the following situations: for example, the air conditioner has any one working mode among the first working mode, the second working mode and the third working mode; for example, the air conditioner has any two working modes among the first working mode, the second working mode and the third working mode; for example, the air conditioner has three working modes: the first working mode, the second working mode and the third working mode.

[0061] In the first working mode, the main air guide plate 31 is at a position closing the air outlet 11, and the auxiliary air guide plate 32 opens the opening 311. For example, the auxiliary air guide plate 32 rotates counterclockwise relative to the main air guide plate 31 to open the opening 311, and the airflow flowing through the air outlet channel 13 in the housing 1 enters the room through the opening 311.

[0062] In the second working mode, the main air guide plate 31 opens the air outlet 11, and the auxiliary air guide plate 32 is located at a position to close the opening 311. For example, the main air guide plate 31 rotates clockwise relative to the housing 1 to open the air outlet 11, and the airflow flowing through the air outlet channel 13 in the housing 1 enters the room through the air outlet 11.

[0063] In the third working mode, the main air guide plate 31 opens the air outlet 11, and the auxiliary air guide plate 32 opens the passage 311. For example, the main air guide plate 31 rotates clockwise relative to the housing 1 to open the air outlet 11, and the auxiliary air guide plate 32 rotates counterclockwise relative to the main air guide plate 31 to open the passage 311. At this time, the air conditioner has two different air outlet paths under the guidance of the main air guide plate 31 and the auxiliary air guide plate 32. The airflow flowing through the air outlet channel 13 in the housing 1 can directly enter the room through the air outlet 11, or the airflow flowing through the air outlet channel 13 in the housing 1 can enter the room through the air outlet 11 and the passage 311.

[0064] By providing the air conditioner with at least one of the first working mode, the second working mode and the third working mode, it is convenient for users to select different working modes according to their needs, so as to better meet the user's usage needs and improve the user experience.

[0065] refer to Figure 1-Figure 4 According to some optional embodiments of the present invention, the air outlet channel 13 has a first side wall 132 and a second side wall 133 that are arranged opposite to each other along the width direction of the air outlet 11, and the second side wall 133 is located above the first side wall 132. The main air guide plate 31 can rotate around the first rotation axis, for example, the main air guide plate 31 can rotate around the first rotation axis in a clockwise direction. The auxiliary air guide plate 32 can rotate around the second rotation axis, for example, the auxiliary air guide plate 32 can rotate around the second rotation axis in a counterclockwise direction, or the auxiliary air guide plate 32 can rotate around the second rotation axis in a clockwise direction. The first rotation axis and the second rotation axis are spaced apart along the width direction of the main air guide plate 31, and the first rotation axis is closer to the first side wall 132 than the second rotation axis. By making the main air guide plate 31 rotatable around the first rotation axis and making the first rotation axis closer to the first side wall 132 relative to the second rotation axis, when the air outlet 11 is opened by rotating the main air guide plate 31, the air flow can be guided by the main air guide plate 31 to flow more toward the upper part of the room, and the air outlet angle and air outlet range at the air outlet 11 can be adjusted by the rotation angle of the main air guide plate 31. By making the auxiliary air guide plate 32 rotatable around the second rotation axis and making the first rotation axis closer to the first side wall 132 relative to the second rotation axis, when the passage 311 is opened by rotating the auxiliary air guide plate 32, the air flow can be guided by the auxiliary air guide plate 32 to flow more toward the lower part of the room, and the air outlet angle and air outlet range at the passage 311 can be adjusted by the rotation angle of the auxiliary air guide plate 32.

[0066] Optionally, when the air conditioner is in heating mode, the auxiliary air guide plate 32 can be rotated counterclockwise around the second rotating axis to adjust the air conditioner to the first working mode, so that the airflow entering the room through the opening 311 flows more toward the indoor direction to optimize the heating comfort of the air conditioner.

[0067] Optionally, when the air conditioner is in cooling mode, the main air guide plate 31 can be rotated clockwise around the first rotation axis, and the air conditioner can be adjusted to the second working mode, so that the air flow entering the room through the air outlet 11 flows more toward the indoor ceiling, so as to optimize the cooling comfort of the air conditioner.

[0068] Optionally, when the air conditioner is in cooling mode or heating mode, the main air guide plate 31 can be rotated in a clockwise direction around the first rotation axis, and the auxiliary air guide plate 32 can be rotated in a counterclockwise direction around the second rotation axis, and the air conditioner is adjusted to the third working mode, so that part of the airflow in the air outlet channel 13 directly enters the room through the air outlet 11, and another part of the airflow in the air outlet channel 13 enters the room through the air outlet 11 and the passage 311 under the joint guiding action of the main air guide plate 31 and the auxiliary air guide plate 32. The airflow speed at the air outlet 11 and the passage 311 of the air conditioner can be reduced, thereby avoiding discomfort to the user due to the airflow directly blowing on the human body, thereby improving the comfort of the air conditioner.

[0069] According to some optional embodiments of the present invention, the air outlet passage 13 has a first side wall 132 and a second side wall 133 which are arranged opposite to each other along the width direction of the air outlet 11, and the first working mode includes an air volume increasing mode. In the air volume increasing mode, the auxiliary air guide plate 32 is located at the downstream side of the first side wall 132 or the second side wall 133 to extend the air outlet length of the first side wall 132 or the second side wall 133. By making the auxiliary air guide plate 32 located at the downstream side of the first side wall 132 or the second side wall 133, the auxiliary air guide plate 32 can guide the airflow in accordance with the flow direction of the airflow in the air outlet passage 13 to extend the air outlet length of the first side wall 132 or the second side wall 133, and the air volume of the airflow entering the room through the through hole 311 can be increased, thereby further improving the air conditioning effect of the air conditioner.

[0070] According to some optional embodiments of the present invention, the first side wall 132 and the second side wall 133 are respectively located at the upper and lower sides of the air outlet channel 13, and the second side wall 133 is located above the first side wall 132. For example, by rotating the auxiliary air guide plate 32 counterclockwise relative to the dominant wind, the auxiliary air guide plate 32 can be located on the downstream side of the second side wall 133 to extend the air outlet length of the second side wall 133, and the airflow can be guided to flow toward the air outlet 11 through the second side wall 133. When the air conditioner is in the air volume increase mode of the first working mode, the auxiliary air guide plate 32 can guide the airflow to flow more toward the lower part of the room (such as the wall) to improve the heating comfort of the air conditioner. For example, the auxiliary air guide plate 32 is rotated in a clockwise direction relative to the dominant wind so that the auxiliary air guide plate 32 is located on the downstream side of the first side wall 132 to extend the air outlet length of the first side wall 132. The airflow can be guided to flow toward the air outlet 11 through the first side wall 132. When the air conditioner is in the air volume increase mode of the first working mode, the auxiliary air guide plate 32 can guide the airflow to flow more toward the upper part of the room (such as the ceiling) to improve the cooling comfort of the air conditioner.

[0071] refer to Figure 1-Figure 4 According to some optional embodiments of the present invention, the air outlet channel 13 has a first side wall 132 and a second side wall 133 which are arranged opposite to each other along the width direction of the air outlet 11, and the second side wall 133 is located above the first side wall 132. The airflow in the air outlet channel 13 flows to the air outlet 11 under the guidance of the first side wall 132 and the second side wall 133. One end of the main air guide plate 31 is rotatably connected to the housing 1, and the connection position of one end of the main air guide plate 31 to the housing 1 is closer to the first side wall 132 than the second side wall 133. In the third working mode, the main air guide plate 31 rotates around one end of the main air guide plate 31, the main air guide plate 31 opens the air outlet 11, the auxiliary air guide plate 32 opens the passage 311, and the auxiliary air guide plate 32 is located in front of the first side wall 132 and is spaced apart from the first side wall 132. The main air guide plate 31 can guide the airflow to flow upward in the room, and the auxiliary air guide plate 32 can guide the airflow to flow downward in the room. Under the guiding effect of the main air guide plate 31 and the auxiliary air guide plate 32, the airflow in the air outlet channel 13 flows into the room through different air outlet paths. Part of the airflow directly enters the room through the air outlet 11; the other part of the airflow enters the room through the air outlet 11 and the through hole 311, which can reduce the airflow speed at the air outlet 11 and the through hole 311 of the air conditioner, avoid the discomfort caused to the user by the airflow directly blowing on the human body, and improve the comfort of the air conditioner.

[0072] Next, we will refer to Figure 1-Figure 4 Air conditioners according to some embodiments of the present invention are described.

[0073] like Figure 1-Figure 4As shown, in this embodiment, the air conditioner is a split wall-mounted air conditioner, and the air conditioner includes an air-conditioning indoor unit 100 and an air-conditioning outdoor unit. The air-conditioning indoor unit 100 includes the above-mentioned casing 1, a heat exchange and air supply component 2, an air guide plate component 3, a first drive mechanism 4 and a second drive mechanism 5. The casing 1 is formed with an air inlet 12, an air outlet 11 and an air outlet channel 13. The heat exchange and air supply component 2 is arranged in the casing 1, and the heat exchange and air supply component 2 is arranged on the upstream side of the air outlet channel 13. The air guide plate component 3 is arranged at the air outlet 11 of the casing 1.

[0074] The air inlet 12 is located at the upper part of the casing 1, and the indoor air flow can enter the air conditioner through the air inlet 12. The air outlet 11 is located at the front side of the casing 1 near the lower part, and the air flow in the air conditioner can enter the room through the air outlet 11. The air outlet channel 13 has a first side wall 132 and a second side wall 133 that are arranged opposite to each other along the width direction of the air outlet 11, and the second side wall 133 is located above the first side wall 132, and the first side wall 132 and the second side wall 133 are used to guide the air flow toward the air outlet 11. The heat exchange and air supply assembly 2 includes a heat exchanger component 21 and an air duct component. The heat exchanger component 21 is located on the upstream side of the air duct component. The air duct component also includes a fan component. The airflow entering the air conditioner through the air inlet 12 flows through the heat exchanger component 21 and exchanges heat with the heat exchanger component 21, thereby achieving the effect of cooling or heating the airflow; then the airflow will flow through the fan component, and under the drive of the fan component, it will flow into the air outlet channel 13, and then flow to the air outlet 11 through the air outlet channel 13, and can enter the room through the air outlet 11.

[0075] The air guide plate assembly 3 includes a main air guide plate 31 and an auxiliary air guide plate 32. The main air guide plate 31 is disposed at the air outlet 11, and the main air guide plate 31 can cover the air outlet 11. A through hole 311 is formed on the main air guide plate 31, which penetrates along the thickness direction of the main air guide plate 31. The auxiliary air guide plate 32 is disposed at the through hole 311, and the auxiliary air guide plate 32 can cover the through hole 311. The main air guide plate 31 includes a main air guide plate body 314 and a fixing plate 313. The fixing plate 313 is located at the other end of the main air guide plate body 314 in the width direction of the main air guide plate 31. One end of the main air guide plate 31 is rotatably connected to the housing 1, and the connection position of one end of the main air guide plate 31 with the housing 1 is closer to the first side wall 132 than the second side wall 133, and the other end of the main air guide plate 31 is closer to the second side wall 133 than the first side wall 132. The other end of the main air guide plate 31 is formed with a matching hole 312 extending in the width direction of the main air guide plate 31. The main air guide plate 31 is rotatable around a first rotation axis, and the auxiliary air guide plate 32 is rotatable around a second rotation axis. The first rotation axis and the second rotation axis are spaced apart in the width direction of the main air guide plate 31, and the first rotation axis is closer to the first side wall 132 than the second rotation axis.

[0076] The first driving mechanism 4 includes a first motor 41 and a transmission mechanism 42. The transmission mechanism 42 includes a transmission gear 421 and a transmission rack 422. The transmission gear 421 is arranged on the motor shaft 411 of the first motor 41, and the transmission rack 422 is meshed with the transmission gear 421. An accommodating cavity 15 is defined between the air duct assembly and the front panel 14 of the housing 1. The first motor 41 and the transmission gear 421 are arranged in the accommodating cavity 15. The transmission rack 422 extends along the upper and lower defense lines and is arranged close to the front panel 14 of the housing 1. A guide column 4221 is provided at the lower end of the transmission rack 422. The guide column 4221 is penetrated through the matching hole 312, and the guide column 4221 is movable relative to the matching hole 312 along the width direction of the guide plate. The transmission rack 422 is connected to the main air guide plate 31 through the guide column 4221. When the first motor 41 outputs power, the transmission gear 421 rotates driven by the motor shaft 411, and the transmission rack 422 moves in the up and down directions driven by the transmission gear 421. The transmission rack 422 drives the other end of the main air guide plate 31 to move, so that the main air guide plate 31 can rotate around the first rotation axis.

[0077] The second driving structure is installed on the main air guide plate 31 , and the second driving mechanism 5 is fixedly connected to the fixing plate 313 . The second driving mechanism 5 can drive the auxiliary air guide plate 32 to rotate relative to the main air guide plate 31 around the second rotation axis.

[0078] like Figure 1 , Figure 3 As shown, the first driving mechanism 4 can drive the main air guide plate 31 to rotate around the first rotating shaft in a clockwise direction to open the air outlet 11; the first driving mechanism 4 can drive the main air guide plate 31 to rotate around the first rotating shaft in a counterclockwise direction to close the air outlet 11.

[0079] like Figure 1-Figure 2 As shown, the second driving mechanism 5 is disposed at one end of the main air guide plate 31 close to the second side wall 133 of the air outlet channel 13, and the second driving mechanism 5 drives the auxiliary air guide plate 32 to rotate around the second rotation axis, and the second rotation axis is also close to the first side wall 132 of the air outlet channel 13. The second driving mechanism 5 can drive the auxiliary air guide plate 32 to rotate around the second rotation axis in a clockwise direction or in a counterclockwise direction. Figure 2 As shown, when the main air guide plate 31 is located at the position of closing the air outlet 11, the second driving mechanism 5 can drive the auxiliary air guide plate 32 to rotate counterclockwise around the second rotation axis to open the opening 311, and the second driving mechanism 5 can drive the main air guide plate 31 to rotate clockwise around the second rotation axis to close the opening 311. Figure 4 As shown, when the dominant wind is at the position to open the air outlet 11, the second driving mechanism 5 can drive the auxiliary air guide plate 32 to rotate counterclockwise around the second rotating axis to open the opening 311, and the second driving mechanism 5 can drive the main air guide plate 31 to rotate clockwise around the second rotating axis to close the opening 311.

[0080] By controlling the air guide plate assembly 3 through the first drive mechanism 4 and the second drive mechanism 5, the working state of the air guide plate assembly 3 can be changed, and the air outlet adjustment of the air guide plate assembly 3 to the air outlet 11 can be made more diversified, so that the air conditioner has a first working mode, a second working mode and a third working mode.

[0081] Next, we will refer to Figure 1-Figure 4 The states of the air guide plate assembly 3 in different working modes of the air conditioner are described.

[0082] like Figure 1 As shown, the air conditioner is in the off mode, the main air guide plate 31 is in the position of closing the air outlet 11, and the auxiliary air guide plate 32 is in the position of closing the opening 311.

[0083] like Figure 2 As shown, the auxiliary air guide plate 32 is driven by the second driving mechanism 5 to rotate counterclockwise around the second rotating shaft to open the through hole 311, and the air conditioner is switched to the first working mode. At this time, the airflow in the air outlet channel 13 will enter the room through the through hole 311, and the airflow will flow toward the lower part of the room. In the first working mode, when the auxiliary air guide plate 32 rotates to a position that conforms to the extension direction of the second side wall 133, the auxiliary air guide plate 32 is located on the downstream side of the second side wall 133, which can extend the air outlet length of the second side wall 133 and enhance the flow rate of the airflow discharged through the through hole 311. At this time, the air conditioner is in the air volume increase mode of the first working mode.

[0084] like Figure 3 As shown, the first driving mechanism 4 drives the main air guide plate 31 to rotate around the first rotating shaft toward the direction away from the air outlet channel 13 to open the air outlet 11. Specifically, the first motor 41 outputs power, the transmission gear 421 rotates under the drive of the motor shaft 411, the transmission rack 422 moves downward under the drive of the transmission gear 421, the transmission rack 422 drives the other end of the main air guide plate 31 to move, and the guide column 4221 of the transmission rack 422 moves relative to the matching hole 312 along the width direction of the main air guide plate 31 toward the end close to the main air guide plate 31, so that the main air guide plate 31 rotates around the first rotating shaft in the clockwise direction to open the air outlet 11. The air conditioner switches to the second working mode, at which time the airflow in the air outlet channel 13 enters the room through the air outlet 11, and the airflow flows toward the upper part of the room.

[0085] like Figure 4As shown, the main air guide plate 31 is driven by the first driving mechanism 4 to rotate in a clockwise direction around the first rotating axis, and the auxiliary air guide plate 32 is driven by the second driving mechanism 5 to rotate in a counterclockwise direction around the second rotating axis, and the air conditioner is switched to the third working mode. At this time, under the common guiding effect of the main air guide plate 31 and the auxiliary air guide plate 32, the airflow in the air outlet channel 13 enters the room through different air outlet paths, wherein part of the airflow enters the room directly through the air outlet 11, and another part of the airflow enters the room through the air outlet 11 and the passage 311.
