[0041] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0042] In this application, the air conditioner performs a refrigeration cycle in its indoor unit using a compressor, condenser, expansion valve, and indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, supplying refrigerant to conditioned and heat-exchanged air. The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it at a high temperature and high pressure. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The indoor heat exchanger evaporates the refrigerant that has expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The indoor heat exchanger achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner's indoor unit can regulate the temperature of the indoor space. The outdoor unit of an air conditioner indoor unit refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner indoor unit includes an indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit. The indoor and outdoor heat exchangers function as either condensers or indoor heat exchangers. When the indoor heat exchanger functions as a condenser, the air conditioner indoor unit acts as a heater in heating mode; when it functions as an indoor heat exchanger, the air conditioner indoor unit acts as a cooler in cooling mode.

[0043] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0044] As attached Figure 1 To be continued Figure 4As shown, in an illustrative embodiment of the indoor unit of the air conditioner of the present invention, the indoor unit includes: a casing, a first air guide plate 100, a first driving component 200, a second air guide plate 300, a second driving component, and a controller, wherein an air outlet is provided thereon; the first air guide plate 100 is disposed at the air outlet, and the first air guide plate 100... The unit has multiple ventilation holes 101. A first air guide plate 100 is used to adjust the lateral air outlet direction. A first driving member 200 drives the first air guide plate 100 to rotate. A second air guide plate 300 is located on the side of the first air guide plate 100 away from the casing. The second air guide plate 300 is used to adjust the longitudinal air outlet direction. A second driving member drives the second air guide plate 300 to rotate. The controller is configured to: when the air conditioner is turned on and running in a uniform and comfortable air supply mode, control the first driving member 200 to rotate the first air guide plate 100 to close the air outlet, so that the airflow is output through the ventilation holes 101; after the first air guide plate 100 closes the air outlet, control the second driving member to rotate the second air guide plate 300 to change the direction of the breeze output through the ventilation holes.

[0045] When enhanced comfort is required, the system enters a uniform and comfortable airflow mode. The controller activates the first drive unit 200, which rotates the first air guide plate 100 to close the air outlet. Air can only exit through the vent 101, resulting in a gentle breeze that reduces airflow intensity and improves comfort. Simultaneously, the controller controls the second drive unit to rotate the second air guide plate 300. The second air guide plate 300 directs the gentle breeze passing through the first vent 101, changing the direction of the gentle breeze output from the indoor unit's air outlet and preventing prolonged airflow in one direction, thus increasing user comfort.

[0046] In some embodiments, when the indoor unit of the air conditioner enters a uniform and comfortable air supply mode, the first air guide plate 100 is in the working position when the multiple first air guide plates 100 close the air outlet.

[0047] Please continue to refer to Figures 1 to 4 In some embodiments, the housing includes a casing and a panel. The casing is horizontally positioned along its length, and the panel is located on the front of the casing. An air outlet is located on the panel and communicates with the interior of the casing. A fan and a heat exchanger are installed inside the casing. The heat exchanger heats or cools the air, and the fan then directs the airflow through the air outlet.

[0048] In some embodiments, the panel is equipped with buttons, which can be used to turn the uniform and comfortable airflow mode on and off. In other embodiments, the uniform and comfortable airflow mode can be turned on or off by an air conditioner remote control.

[0049] In some embodiments, the air outlet is rectangular, and the length direction of the air outlet is set along the length direction of the panel.

[0050] In some embodiments, there are multiple first air guide plates 100, and the multiple first air guide plates 100 are spaced apart along the length direction of the air outlet. In some embodiments, the spacing between any two adjacent first air guide plates 100 is the same. The first driving member 200 can drive all the first air guide plates 100 to rotate, and the multiple first air guide plates 100 remain parallel to each other during the movement. When all the first air guide plates 100 are on the same plane, the first air guide plates 100 are in a closed air outlet state, and the air is output through the vent holes 101 on each first air guide plate 100.

[0051] In some embodiments, the first air guide plate 100 is a rectangular plate, and the length direction of the first air guide plate 100 is arranged along the width direction of the air outlet. The two ends of the length direction of the first air guide plate 100 are respectively rotatably connected to the two inner sidewalls corresponding to the air outlet.

[0052] In some embodiments, a first rotating shaft is provided at both ends of the first air guide plate 100 along its length. The two first rotating shafts on each first air guide plate 100 are coaxially arranged, and the axial direction of the first rotating shaft is the same as the length direction of the first air guide plate 100. Multiple first insertion holes are provided on the two inner sidewalls corresponding to the air outlet, and the number of multiple first insertion holes on the two inner sidewalls of the air outlet is the same as the number of first air guide plates 100. The first rotating shaft is inserted into the corresponding first insertion hole one by one, and the first rotating shaft rotates within the corresponding first insertion hole.

[0053] Please continue to refer to Figures 1 to 4 In some embodiments, the first insertion holes are respectively opened at both ends of the length direction of the first air guide plate 100. The first insertion holes are circular holes, and the two first insertion holes on the first air guide plate 100 are coaxially arranged. Multiple first rotating shafts are respectively arranged on the two side walls corresponding to the air outlet. The first rotating shafts are corresponding to the first insertion holes, and the first rotating shafts rotate in the corresponding first insertion holes.

[0054] In some embodiments, all the first air guide vanes 100 have the same shape.

[0055] In some embodiments, the vent 101 is a circular hole, and there are multiple vent 101s arranged in an array on the first air guide plate 100. The vent 101s penetrate the first air guide plate 100 along its thickness direction. The multiple vent 101s are distributed along the length and width directions of the first air guide plate 100. The spacing between any two adjacent vent 101s is the same.

[0056] In some embodiments, the vent 101 is a square hole, and there are multiple vent 101s arranged in an array on the first air guide plate 100. The vent 101s penetrate the first air guide plate 100 along its thickness direction. The multiple vent 101s are distributed along the length and width directions of the first air guide plate 100. The spacing between any two adjacent vent 101s is the same.

[0057] In some embodiments, when it is necessary to adjust the airflow direction, a signal is sent to the controller via the control panel or remote control. The controller controls the first drive member 200 to rotate, and the first drive member 200 drives the first air guide plate 100 to flip. The air is guided by the first air guide plate 100, thereby realizing the lateral adjustment of the output airflow.

[0058] In some embodiments, the panel has multiple air outlets, and each air outlet is provided with a first air guide plate 100 and a second air guide plate 300.

[0059] Please continue to refer to Figures 1 to 4 In some embodiments, the second air guide plate 300 is horizontally arranged, and there are multiple second air guide plates 300 arranged along the width direction of the air outlet. Both ends of the second air guide plate 300 are rotatably connected to the air outlet of the panel. When multiple second air guide plates 300 are located on the same plane, the multiple second air guide plates 300 close the air outlet.

[0060] In some embodiments, a support member is further provided inside the air outlet, the support member being arranged along the width direction of the air outlet, and both ends of the support member being connected to the panel. The second air guide plate 300 is also rotatably connected to the support member. The support member supports the second air guide plate 300, improving the stability of the second air guide plate 300 when rotating.

[0061] In some embodiments, the second air guide plate 300 has three connecting plates on the side facing the first air guide plate 100, two of which are respectively located at both ends of the second air guide plate 300, and the third connecting plate is located in the middle of the second air guide plate 300 and on any side of the support member. Second rotating shafts are respectively provided on both side walls along the length of the air outlet, and a second rotating shaft is also provided on the side of the support member facing the corresponding connecting plate. The second rotating shafts pass through the corresponding connecting plates, and when the second air guide plate 300 rotates, the second air guide plate 300 drives the connecting plates to rotate around the second rotating shafts. In some embodiments, among the three connecting plates of the second air guide plate 300, one of the second rotating shafts is fixedly connected to the corresponding connecting plate, and this second rotating shaft is connected to the output shaft of the second drive member. The second drive member is activated to drive the corresponding second air guide plate 300 to rotate.

[0062] In some embodiments, the second driving element is a second stepper motor.

[0063] Please refer to Figures 5 to 7In some embodiments, the second air guide plate 300 is provided with a first position, a second position and a third position. The minimum angle between the second position and the horizontal direction is smaller than the minimum angle between the first position and the horizontal direction, and the minimum angle between the third position and the horizontal direction is smaller than the minimum angle between the second position and the horizontal direction. The controller controls the second driving member to drive the second air guide plate 300 to switch between the first position, the second position or the third position to change the direction of the breeze output from the air outlet.

[0064] In some embodiments, the second air guide plate 300 is further provided with an initial position. When the second air guide plate 300 is in the initial position, the air guide plate is in a horizontal state; when the indoor unit of the air conditioner is turned on, the second air guide plate 300 enters the initial position. The second air guide plate 300 first enters the initial position to facilitate the reset of the second driving component and ensure the accuracy of the angle of subsequent operation.

[0065] In some embodiments, a vertical baseline is provided, which is perpendicular to the horizontal plane, and the top of the vertical baseline is located on the axis of the second rotating shaft. The angle between the width direction of the second air guide plate 300 and the vertical baseline is 90°.

[0066] Please refer to Figures 5 to 7 In some embodiments, after the first air guide plate 100 closes the air outlet, the second air guide plate 300 enters the first stage, and the second air guide plate 300 sequentially enters the first position, the third position, and the first position; after the first stage is completed, it enters the second stage, and the second air guide plate 300 sequentially enters the second position, the first position, and the second position; after the second stage is completed, it enters the third stage, and the second air guide plate 300 sequentially enters the third position, the second position, the third position, and the first position; after the third stage is completed, it enters the first stage again.

[0067] In some embodiments, after the indoor unit of the air conditioner enters the uniform and comfortable air supply mode, the controller controls the first driving component 200 to drive the first air guide plate 100 to flip and close the air outlet, and the second air guide plate 300 enters the initial position. After the second air guide plate 300 enters the initial position, it enters the first stage.

[0068] In some embodiments, the second air guide vane 300 has a normal position, which is reached after the uniform and comfortable air supply mode is deactivated. Pressing the end button deactivates the uniform and comfortable air supply mode. The second air guide vane 300 disengages from any of the actions in the first, second, and third stages, and returns to its normal position.

[0069] Please refer to Figures 5 to 7 In some embodiments, pressing the end button deactivates the uniform and comfortable air supply mode of the indoor air conditioner. After completing the first, second, and third stages of this cycle, the second air guide 300 returns to its normal position.

[0070] In some embodiments, the time from the entry of the second air guide plate 300 into the first stage to the end of the third stage is 45 to 60 seconds.

[0071] In some embodiments, the time from the entry of the second air guide plate 300 into the first stage to the end of the third stage is 50 seconds.

[0072] In some embodiments, the minimum angle between the second air guide plate 300 and the horizontal direction when the second air guide plate 300 is in the first position is 50° to 70°; the minimum angle between the second air guide plate 300 and the horizontal direction when the second air guide plate 300 is in the second position is 20° to 35°; and the minimum angle between the second air guide plate 300 and the horizontal direction when the second air guide plate 300 is in the third position is 5° to 20°.

[0073] In some embodiments, in the uniform and comfortable air supply mode, the minimum angle between the second air guide plate 300 and the horizontal direction when it is in the first position is 50° to 60°; the minimum angle between the second air guide plate 300 and the horizontal direction when it is in the second position is 20° to 25°; and the minimum angle between the second air guide plate 300 and the horizontal direction when it is in the third position is 5° to 10°.

[0074] In some embodiments, the indoor unit of the air conditioner also has an air supply mode, a dehumidification mode, and a cooling mode. When the indoor unit of the air conditioner is in the air supply mode, dehumidification mode, and cooling mode, the controller controls the second drive unit to drive the second air guide plate 300 to cycle through the first stage, the second stage, and the third stage, and the flipping angle and sequence of the second air guide plate 300 are the same as in the uniform and comfortable air supply mode.

[0075] In some embodiments, the indoor unit of the air conditioner also has a heating mode. After the indoor unit enters the heating mode, the controller controls the second drive component to drive the second air guide plate 300 to cycle through the first stage, the second stage, and the third stage. When the second air guide plate 300 is in the first position, the minimum angle with the horizontal direction is 60° to 70°; when the second air guide plate 300 is in the second position, the minimum angle with the horizontal direction is 30° to 35°; and when the second air guide plate 300 is in the third position, the minimum angle with the horizontal direction is 15° to 20°.

[0076] Please refer to Figures 8 to 10 In some embodiments, a connecting rod 400 is provided inside the housing, and the first air guide plate 100 is rotatably connected to the housing; one side of the first air guide plate 100 is rotatably connected to the connecting rod 400; the first driving member 200 drives the connecting rod 400 to move along the length direction to cause each first air guide plate 100 to rotate. Multiple first air guide plates 100 can be rotated synchronously by one first driving member 200, saving costs.

[0077] In some embodiments, each of the first air guide plates 100 is provided with a guide shaft 500 on the side facing the connecting rod 400; the connecting rod 400 is provided with a number of bushings 600 that are the same as the number of guide shafts 500 and correspond one-to-one; the guide shaft 500 is rotatably connected to the corresponding bushing 600. The shaft rotates stably within the corresponding bushing 600.

[0078] In some embodiments, one side of the bushing 600 is open, allowing the guide shaft 500 to be directly pressed into the bushing 600. During assembly, the bushing 600 undergoes elastic deformation. The diameter of the guide shaft 500 is L3, and the opening width of the bushing 600 is L4; therefore, L3 - L4 = 0.5 mm - 0.8 mm. This design ensures that the guide shaft 500 will not detach from the bushing 600, guaranteeing the reliability of the assembly between the guide shaft 500 and the bushing 600.

[0079] In some embodiments, the width of the first air guide plate 100 is L1, and the axial distance between any two adjacent guide shafts 500 is L2, where L2-L1≤5mm. Air can also be output from the gap between any two adjacent first air guide plates 100. Because the distance between the two first air guide plates 100 is less than 5mm, the airflow intensity output through the gap between the two first air guide plates 100 is also reduced to a light breeze. This further reduces discomfort when airflow blows towards the user and improves comfort.

[0080] In some embodiments, the first drive member 200 is a first stepper motor; the air conditioner also includes a first crank 700 and a second crank 800, one end of the first crank 700 is rotatably connected to the output shaft of the first stepper motor; one end of the second crank 800 is hinged to the end of the first crank 700 away from the first stepper motor, and the other end of the second crank 800 is hinged to the connecting rod 400.

[0081] Please refer to Figures 8 to 10 In some embodiments, the second crank 800 and the connecting rod 400 are connected by a third crank 900, one end of which is hinged to the housing or panel, and the other end of which is hinged to the end of the connecting rod 400. The end of the second crank 800 away from the first crank 700 is hinged to the middle section of the third crank 900, and the range of motion of the connecting rod 400 can be adjusted by the third crank 900.

[0082] In some embodiments, a fixing member 110 is provided on the panel, and a guide groove 111 is provided through the fixing member 110. One end of the first crank 700 and the second crank 800 is hinged and limited to the guide groove 111 to achieve guidance and improve the stability of the structure operation.

[0083] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
