[0033] Currently, with the improvement of people's living standards, the popularity rate of air conditioners is getting higher and higher. However, the air supply methods of conventional air conditioners are mostly relatively single, and can only achieve simple upward air blowing or downward air blowing. For this reason, related technologies have proposed an air conditioner indoor unit, including: a heat exchange main body, including a heat exchange housing and a heat exchanger disposed in the heat exchange housing, the heat exchange housing is provided with a heat exchange air outlet for blowing out heat exchange air; an air distribution arm, disposed outside the heat exchange housing and moving relative to the heat exchange housing to change the position of the air distribution arm relative to the heat exchange air outlet; a driving mechanism, connected to the air distribution arm for driving the air distribution arm to move relative to the heat exchange main body.

[0034] Related technologies can make the heat exchange air after acting on the air distribution arm more meet the user's needs. However, when the user has an urgent air distribution demand, related technologies cannot accurately control the position of the air distribution arm to achieve the best air distribution effect.

[0035] Combined with Figure 1-2 As shown, the embodiments of the present disclosure provide an air conditioner, including: an indoor unit 10, an air distribution plate 20, and a connecting arm 30. The indoor unit 10 has an air duct 11 internally configured, and an air outlet 12 is provided at the end of the air duct 11. The air distribution plate 20 is movably disposed at the air outlet 12. The connecting arm 30 is movably connected between the air distribution plate 20 and the indoor unit 10.

[0036] By using the air conditioner provided in the embodiments of the present disclosure, a movable connecting arm 30 and an air distribution plate 20 are provided at the air outlet 12 of the indoor unit 10. Combining with the specific operation mode of the air conditioner, the embodiments of the present disclosure can control the air distribution plate 20 to move to a suitable position relative to the indoor unit 10, so that the air distribution plate 20 can perform a function matching the operation mode, thereby being able to improve the actual operation effect of the air conditioner and further being beneficial to improving the user's comfort.

[0037] Optionally, the indoor unit 10 has a bottom case 131, a top case 132, a front case 133, a rear case 134, a first side case, and a second side case. In this way, the indoor unit 10 can be protected by the above-mentioned outer case, and an internal space for accommodating the heat exchange components can be defined.

[0038] Optionally, the air duct 11 is formed by the air duct profile 111. In this way, the air duct profile 111 can be arranged inside the indoor unit 10, so that the air duct 11 can be constructed to assist in forming an air circulation inside the indoor unit 10.

[0039] Optionally, the air duct profile 111 extends outward to form an air outlet extension surface 112. Here, the air outlet extension surface 112 does not constitute a physical component of the air conditioner. It is only an extension of the air duct profile 111 in the spatial concept and is used to describe its positional relationship with physical components such as the air distribution plate 20. Thus, it can assist physical components such as the air distribution plate 20 to move to appropriate positions, which is beneficial to improving the actual operation effect of the air conditioner.

[0040] Optionally, the shape of the connecting arm 30 is J-shaped. In this way, by setting the connecting arm 30 with a J-shaped configuration, the movement range of the connecting arm 30 and the air distribution plate 20 can be increased, so that the air distribution plate 20 can move relative to the indoor unit 10 to more extreme positions. For example, in some embodiments, the air distribution plate 20 can move to directly below the bottom case 131 of the indoor unit 10 to reach the reference position when the air conditioner is in standby.

[0041] Optionally, the air distribution plate 20 has a leading edge 21, a trailing edge 22, an air distribution surface 23, and a leeward surface 24. Here, the side of the air distribution plate 20 facing the air outlet 12 is the air distribution surface 23, and the side away from the air outlet 12 is the leeward surface 24, and the air distribution surface 23 and the leeward surface 24 are parallel. At the same time, the end of the air distribution plate 20 facing the front case 133 is the leading edge 21, and the end away from the front case 133 is the trailing edge 22. When the air conditioner is turned off, the leading edge 21 of the air distribution plate 20 abuts against the lower end of the front case 133 of the indoor unit 10, and the trailing edge 22 of the air distribution plate 20 abuts against the front end of the bottom case 131 of the indoor unit 10, so as to be able to close the air outlet 12 and stop the indoor unit 10 from delivering heat exchange air to the room.

[0042] It should be understood that the air distribution plate 20 in the embodiments of the present disclosure has a different design from the air deflector in a conventional air conditioner. In some embodiments, the air distribution plate 20 can perform functions similar to those of the air deflector, such as assisting in adjusting the air outlet direction of the heat exchange air. In other embodiments, the air distribution plate 20 can perform functions that the air deflector does not have to achieve more and better effects, thereby matching the operation mode of the air conditioner. Therefore, the actual operation effect of the air conditioner can be improved, which is beneficial to improving the user's comfort.

[0043] Optionally, the air conditioner further includes a wind deflector 40. The wind deflector 40 is movably disposed at the air outlet 12. In this way, the air outlet direction of the heat exchange air in the air duct 11 can be guided by the wind deflector 40 to meet the comfort requirements of the user.

[0044] Optionally, the wind deflector 40 has a wind guiding surface 41. Here, the side of the wind deflector 40 facing the air duct surface 111 is the wind guiding surface 41. By adjusting the angle between the wind guiding surface 41 and the horizontal plane, the air outlet direction of the heat exchange air can be accurately controlled, which is beneficial to meeting the comfort requirements of the user.

[0045] Optionally, the air conditioner further includes an internal blower 50. The internal blower 50 is disposed in the air duct 11. In this way, in combination with the specific operating mode of the air conditioner, the embodiments of the present disclosure can control the internal blower 50 to operate at different speeds, thereby generating a variety of appropriate wind speed gears. Therefore, the actual operating effect of the air conditioner can be improved, which is beneficial to improving the comfort of the user.

[0046] Optionally, the air conditioner further includes an indoor heat exchanger. The indoor heat exchanger is disposed in the air duct 11 relative to the internal blower 50. In this way, when the air conditioner operates in the cooling mode, the indoor heat exchanger works as an evaporator. Through the heat exchange effect, it can absorb heat and evaporate the low-temperature liquid refrigerant inside, so as to produce lower-temperature heat exchange air in the air duct 11 to achieve the purpose of cooling the indoor environment. When the air conditioner operates in the heating mode, the indoor heat exchanger works as a condenser. Through the heat exchange effect, it can release heat and condense the high-temperature gaseous refrigerant inside, so as to produce higher-temperature heat exchange air in the air duct 11 to achieve the purpose of heating the indoor environment.

[0047] Optionally, the air conditioner further includes a driving device. The driving device includes a first motor 61, a second motor 62, and a third motor 63. The first motor 61 is connected to the air distribution plate 20 and is used to drive the air distribution plate 20 to rotate. The second motor 62 is connected to the connecting arm 30 and is used to drive the connecting arm 30 to rotate. The third motor 63 is connected to the wind deflector 40 and is used to drive the wind deflector 40 to rotate. In this way, the embodiments of the present disclosure can set the driving device to drive the relevant air outlet components to rotate reasonably. Specifically, the first motor 61 can be used to drive the air distribution plate 20 to move to a suitable position, so that the function matching the operating mode can be executed. Therefore, the actual operating effect of the air conditioner can be improved, which is beneficial to improving the comfort of the user. The second motor 62 can be used to drive the connecting arm 30 to rotate to a suitable angle, and then the air distribution plate 20 connected thereto can be assisted to move to more extreme positions to achieve more and better effects, which is beneficial to matching more operating modes. The third motor 63 can be used to drive the wind deflector 40 to rotate to a suitable angle, so that the air outlet direction of the heat exchange air can be guided to meet the comfort requirements of the user.

[0048] Optionally, the operating modes of the air conditioner include one or more of a cooling mode, a heating mode, a uniform air distribution mode, a blowing mode, an embracing air mode, and a direct air blowing prevention mode. Corresponding to the above different operating modes, the working positions of the uniform air distribution plate 20 and the connecting arm 30 are different, so that the uniform air distribution plate 20 performs different functions and matches the operating mode. In addition, the working position of the air deflector 40 is also different, and / or the operating speed of the indoor fan 50 is also different, so as to meet the diverse needs of users.

Among them, the arrows show part of the air outlet path. a2 is the angle between the air distribution surface 23 of the air distribution plate 20 and the horizontal plane (at this time, the front edge 21 of the air distribution plate 20 is lower than the rear edge 22 of the air distribution plate 20); b2 is the angle between the straight line segment of the connecting arm 30 and the horizontal plane (at this time, the straight line segment facing the air distribution plate 20 is lower than the straight line segment away from the air distribution plate 20); c2 is the angle between the air guiding surface 41 of the air guiding plate 40 and the horizontal plane (at this time, the front edge of the air guiding plate 40 is lower than the rear edge of the air guiding plate 40); h2 is the vertical distance between the rear edge 22 of the air distribution plate 20 and the bottom case 131 of the indoor unit 10 (at this time, the rear edge 22 of the air distribution plate 20 is lower than the bottom case 131 of the indoor unit 10).

[0059] Combined Figure 5As shown in the figure, an embodiment of the present disclosure provides a schematic diagram of the state of an air conditioner in the surrounding air mode. Among them, the arrows show part of the air outlet path. a3 is the angle between the air distribution surface 23 of the air distribution plate 20 and the horizontal plane (at this time, the front edge 21 of the air distribution plate 20 is higher than the rear edge 22 of the air distribution plate 20); b3 is the angle between the straight line segment of the connecting arm 30 and the horizontal plane (at this time, the straight line segment facing the air distribution plate 20 is lower than the straight line segment away from the air distribution plate 20); c3 is the angle between the air guiding surface 41 of the air guiding plate 40 and the horizontal plane (at this time, the front edge of the air guiding plate 40 is higher than the rear edge of the air guiding plate 40); h3 is the vertical distance between the rear edge 22 of the air distribution plate 20 and the bottom shell 131 of the indoor unit 10 (at this time, the rear edge 22 of the air distribution plate 20 is lower than the bottom shell 131 of the indoor unit 10).

[0064] Optionally, the air conditioner further includes a control device 70 for the air conditioner. The control device 70 for the air conditioner is installed in the indoor unit 10 and is electrically connected to the air distribution plate 20 and the connecting arm 30. In this way, the embodiment of the present disclosure can execute corresponding control methods through the control device 70 to better match the operation mode of the air conditioner.

[0065] Based on the above air conditioner, combined with Figure 6As shown in the figure, an embodiment of the present disclosure provides a control method for an air conditioner, including:

[0066] S101, the processor responds to an instruction of the air distribution mode and controls the connecting arm to rotate to a first preset position.

[0067] S102, the processor controls the air distribution plate to rotate to a first target position so that the leading edge of the air distribution plate is located on the extended air outlet surface of the air duct.

[0068] When using the control method for an air conditioner provided by the embodiment of the present disclosure, when the user has a need for air distribution, the air conditioner responds to an instruction of the air distribution mode, controls the connecting arm to rotate to a first preset position, and controls the air distribution plate to rotate to a first target position so that the leading edge of the air distribution plate is located on the extended air outlet surface of the air duct. Thus, the embodiment of the present disclosure enables the air distribution plate to draw an appropriate proportion of ambient air from the room to mix with the heat exchange air in the air duct, thereby sending out gentle air that is cool but not cold and warm but not dry. Therefore, the best air distribution effect can be achieved, which is beneficial to improving the comfort of users.

[0069] Optionally, the instruction of the air distribution mode includes one or more of a start instruction, a gear instruction, a swing instruction, and a close instruction. Among them, the start instruction is used to control the air conditioner to enter the air distribution mode. The gear instruction is used to control the air conditioner to switch to the corresponding gear of the air distribution mode. The swing instruction is used to control the air conditioner to swing the air outlet in the air distribution mode. The close instruction is used to control the air conditioner to exit the air distribution mode. In this way, precise control of the air distribution mode can be achieved through the above instructions.

[0070] Optionally, as shown in Figure 3 the figure, when the connecting arm is in the first preset position, the straight line segment of the connecting arm facing the air distribution plate is lower than the straight line segment of the connecting arm away from the air distribution plate, and the angle between the straight line segment of the connecting arm and the horizontal plane is b1.

[0071] Optionally, as shown in Figure 3 the figure, when the air distribution plate is in the first target position, the leading edge of the air distribution plate is located on the extended air outlet surface of the air duct, the vertical distance between the trailing edge of the air distribution plate and the bottom shell of the indoor unit is h1, the leading edge of the air distribution plate is lower than the trailing edge of the air distribution plate, and the angle between the air distribution surface of the air distribution plate and the horizontal plane is a1.

[0072] Optionally, after the processor controls the air distribution plate to rotate to the first target position so that the leading edge of the air distribution plate is located on the extended air outlet surface of the air duct, the following steps are further included: the processor responds to a gear command and determines the first compensation position of the air distribution plate according to the gear of the air distribution mode; the processor controls the air distribution plate to rotate to the first compensation position to maintain or reduce the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit. In this way, when it is recognized that there is also a gear command, the embodiment of the present disclosure can control the air distribution plate to rotate from the first target position to the corresponding first compensation position according to the gear of the air distribution mode, so as to adaptively adjust the air distribution ratio of the environmental air drawn from the room, thereby being able to reasonably match the air distribution effect required by the user and being beneficial to improving the user's comfort level.

[0073] Optionally, the gear of the air distribution mode is negatively correlated with the included angle between the first compensation position and the first target position. That is, in the air distribution mode, the smaller the gear, the larger the included angle between the corresponding first compensation position and the first target position. In this way, when the user's air distribution requirement is relatively weak, they may expect the actual air outlet to be closer to the heat exchange air. Therefore, the embodiment of the present disclosure can set the first compensation position with a larger included angle relative to the first target position to greatly reduce the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit, thereby being able to reduce the air distribution ratio of the environmental air drawn from the room so that the actual air outlet of the air conditioner can be closer to the heat exchange air, and thus being able to meet the air distribution effect required by the user and being beneficial to improving the user's comfort level.

[0074] Optionally, the gears of the air distribution mode include first - gear air distribution, second - gear air distribution, and third - gear air distribution. Among them, the air distribution effect of the first - gear air distribution is weaker than that of the second - gear air distribution, and the air distribution effect of the second - gear air distribution is weaker than that of the third - gear air distribution. In this way, the air distribution ratios of each gear for drawing environmental air from the room are different. When the air distribution mode is first - gear air distribution, the air distribution ratio of the environmental air drawn from the room is small, and the actual air outlet of the air conditioner is mainly the heat exchange air of the air duct. At this time, the air distribution effect is weak, but it can preferentially meet the user's rapid cooling and heating requirements. When the air distribution mode is second - gear air distribution, the air distribution ratio of the environmental air drawn from the room is slightly higher, and the actual air outlet of the air conditioner is a mixed air composed of the heat exchange air of the air duct and the environmental air in the room. At this time, the air distribution effect is medium, and thus a relatively soft and comfortable air can be sent out to slightly improve the user's comfort level. When the air distribution mode is third - gear air distribution, the air distribution ratio of the environmental air drawn from the room is the largest, and the air conditioner can mix more indoor environmental air with the heat exchange air of the air duct, thereby being able to send out a soft wind that is cool but not cold and hot but not dry to achieve the best air distribution effect, which is beneficial to better improving the user's comfort level.

[0075] Optionally, the processor determines a first compensation position of the air distribution plate according to the gear of the uniform air distribution mode, including: when the uniform air distribution mode is the first gear of uniform air distribution, determining that the included angle between the first compensation position of the air distribution plate and the first target position is a first angle; or, when the uniform air distribution mode is the second gear of uniform air distribution, determining that the included angle between the first compensation position of the air distribution plate and the first target position is a second angle; or, when the uniform air distribution mode is the third gear of uniform air distribution, determining that the included angle between the first compensation position of the air distribution plate and the first target position is a third angle. Wherein, the first angle is greater than the second angle, and the second angle is greater than the third angle.

[0076] In this way, when the uniform air distribution mode is the first gear of uniform air distribution, the embodiment of the present disclosure can make the air distribution plate rotate a relatively larger first angle based on the first target position, thereby greatly reducing the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit, so as to significantly reduce the uniform air distribution ratio of the environmental air drawn from the room. At this time, the actual air output of the air conditioner is mainly the heat exchange air of the air duct, and the uniform air distribution effect is weak, but it can preferentially meet the user's rapid cooling and heating needs. When the uniform air distribution mode is the second gear of uniform air distribution, the embodiment of the present disclosure can make the air distribution plate rotate a slightly larger second angle based on the first target position, thereby appropriately reducing the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit, so as to slightly reduce the uniform air distribution ratio of the environmental air drawn from the room. At this time, the actual air output of the air conditioner is a mixed air composed of the heat exchange air of the air duct and the environmental air in the room, and the uniform air distribution effect is medium, so that a relatively soft and comfortable air can be sent out, thereby slightly improving the user's comfort. When the uniform air distribution mode is the third gear of uniform air distribution, the embodiment of the present disclosure can make the air distribution plate rotate a very small third angle based on the first target position, or not rotate to maintain the first target position, so as to maintain a relatively high level of the uniform air distribution ratio of the environmental air drawn from the room. At this time, the air conditioner can mix more indoor environmental air with the heat exchange air of the air duct, so as to send out a soft wind that is cool but not cold and hot but not dry, so as to achieve the best uniform air distribution effect, which is beneficial to better improving the user's comfort.

[0077] Preferably, the first angle is 40°. At this time, the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit is 3 mm, and only a very small amount of indoor environmental air can be mixed with the heat exchange air of the air duct through the uniform air distribution surface of the air distribution plate. Therefore, the actual air output is mainly the heat exchange air of the air duct. The first angle can also be adjusted according to the actual needs of the user, and can also be set to other arbitrary reasonable values such as 38° or 42°.

[0078] Preferably, the second angle is 20°. At this time, the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit is 21 mm, and part of the indoor environmental air can be mixed with the heat exchange air of the air duct through the uniform air distribution surface of the air distribution plate to send out a relatively soft and comfortable air. The second angle can also be adjusted according to the actual needs of the user, and can also be set to other arbitrary reasonable values such as 18° or 22°.

[0079] Preferably, the third angle is 0°. At this time, the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit is 42 mm. A relatively large amount of indoor ambient air can be mixed with the heat exchange air in the air duct through the air distribution surface of the air distribution plate, so as to send out gentle air that is cool but not cold and warm but not dry. The third angle can also be adjusted according to the actual needs of the user, and can also be set to other arbitrary reasonable values such as 1° or 2°.

[0080] Optionally, the air distribution mode in the embodiments of the present disclosure may further include more gears, not limited to the above three gears. The working positions of the air distribution plate, the connecting arm and the air guide plate can be reasonably set according to the various gears of the above air distribution mode, and will not be listed one by one here. At the same time, based on the various gears of the above air distribution mode, the air conditioner can make corresponding function adjustments to match the air distribution effect required by the user, thereby improving the comfort of the user.

[0081] Optionally, after the processor controls the air distribution plate to rotate to the first target position so that the leading edge of the air distribution plate is located on the air outlet extension surface of the air duct, it further includes: the processor responds to the swing instruction and controls the air distribution plate to periodically rotate within the first angle range with the first target position as the middle position. In this way, when it is recognized that there is also a swing instruction, the embodiments of the present disclosure can control the air distribution plate to periodically rotate within the first angle range with the first target position as the middle position, so as to realize swing air distribution in the air distribution mode and send out more gentle and comfortable air.

[0082] Optionally, the first angle range can be set in combination with the difference between the indoor ambient temperature and the air conditioner set temperature. Preferably, the first angle range can be set to [-5°, 5°], and the air distribution plate is controlled to periodically rotate with the first target position as the middle position. It should be understood that the first angle range refers to the set of included angles between the multiple positions where the air distribution plate periodically rotates and the first target position. For example, when the air distribution plate swings to the first target position, the included angle is 0°. Further, when the absolute value of the difference between the indoor ambient temperature and the air conditioner set temperature is greater than the first preset temperature difference, the first angle range can be appropriately increased, for example, adjusted to [-8°, 8°], so as to continuously adjust the air distribution ratio of the ambient air drawn from the room, so as to reasonably optimize the air distribution effect when the indoor temperature difference is large, so as to avoid the air outlet being too gentle to meet the user's rapid cooling and heating needs. The first angle range can also be adjusted according to the actual needs of the user, and can also be set to other arbitrary reasonable ranges.

[0083] Optionally, after the processor responds to an instruction for the uniform air distribution mode, it further includes: the processor controls the air deflector to rotate to a target air deflector position, so that the air guiding surface of the air deflector is parallel to the extended air outlet surface of the air duct. In this way, when an instruction for the uniform air distribution mode is received, the embodiments of the present disclosure control the air deflector to rotate to the target air deflector position, thereby being able to reasonably guide the air outlet direction of the heat exchange air in the air duct. By making the air guiding surface of the air deflector parallel to the extended air outlet surface of the air duct, the embodiments of the present disclosure can increase the air supply distance of the air conditioner to achieve a better air supply effect, which is beneficial to improving the comfort of users.

[0084] Optionally, in combination with Figure 3 As shown, when the air deflector is in the target air deflector position, the leading edge of the air deflector is lower than the trailing edge of the air deflector, and the included angle between the air guiding surface of the air deflector and the horizontal plane is c1.

[0085] Optionally, after the processor controls the air deflector to rotate to the target air deflector position so that the air guiding surface of the air deflector is parallel to the extended air outlet surface of the air duct, it further includes: the processor responds to a swing instruction and controls the air deflector to periodically rotate within a third angle range with the target air deflector position as the intermediate position. In this way, when it is recognized that there is also a swing instruction, the embodiments of the present disclosure can control the air deflector to periodically rotate within a third angle range with the target air deflector position as the intermediate position, thereby being able to achieve swing air guiding in the uniform air distribution mode to avoid discomfort caused by long-term direct blowing to users. Furthermore, it can cooperate with the swing of the air deflector to simultaneously send out a more gentle and comfortable air flow to better improve the comfort of users.

[0086] Optionally, the third angle range can be set in combination with the difference between the indoor ambient temperature and the air conditioner set temperature. Preferably, the third angle range can be set to [-5°, 5°] to control the air deflector to periodically rotate with the target air deflector position as the intermediate position. It should be understood that the third angle range refers to the set of included angle angles between the multiple positions where the air deflector periodically rotates and the target air deflector position. For example, when the air deflector swings to the target air deflector position, the included angle angle is 0°. Further, when the absolute value of the difference between the indoor ambient temperature and the air conditioner set temperature is greater than the second preset temperature difference, the third angle range can be appropriately reduced, for example, adjusted to [-3°, 3°], so that the air outlet direction of the heat exchange air is relatively concentrated, thereby being able to reasonably optimize the air supply effect when the indoor temperature difference is large to avoid the user's cold and hot feelings being not obvious due to overly dispersed air supply. The third angle range can also be adjusted according to the actual needs of users and can also be set to any other reasonable range.

[0087] Optionally, after the processor responds to the instruction of the air uniform distribution mode, it further includes: the processor controls the internal fan to operate at a first target speed. In this way, when receiving the instruction of the air uniform distribution mode, the embodiment of the present disclosure controls the internal fan to operate at the first target speed, so that the air outlet speed of the air conditioner can be reasonably set to match the current air uniform distribution mode, which is beneficial to better ensuring the air uniform distribution effect and improving the user's comfort.

[0088] Preferably, the first target speed is 1000 r / min to correspond to the air uniform distribution mode of the air conditioner, so as to be able to send out soft air that is cool but not cold and warm but not dry. The first target speed can also be adjusted in combination with the gear instruction of the air uniform distribution mode, and can also be set to other reasonable values such as 900 r / min or 800 r / min.

[0089] Optionally, after the processor controls the internal fan to operate at the first target speed, it further includes: the processor responds to the gear instruction, determines the first corrected speed of the internal fan according to the gear of the air uniform distribution mode; the processor controls the internal fan to operate at the first corrected speed. Wherein, the first corrected speed is less than or equal to the first target speed. In this way, when it is recognized that there is also a gear instruction, the embodiment of the present disclosure can determine the corresponding first corrected speed according to the gear of the air uniform distribution mode, and control the speed of the internal fan to decrease from the first target speed to the first corrected speed, so as to adaptively adjust the air outlet speed of the air conditioner, and thus can reasonably match the actual air uniform distribution effect of the air conditioner, which is beneficial to ensuring the user's comfort.

[0090] Optionally, the gear of the air uniform distribution mode is negatively correlated with the speed difference between the first target speed and the first corrected speed. That is, in the air uniform distribution mode, the smaller the gear, the larger the speed difference between the corresponding first target speed and the first corrected speed. In this way, when the gear of the air uniform distribution mode is small, the actual air outlet of the air conditioner is mainly the heat exchange air in the air duct. At this time, the air uniform distribution effect is weak, and it is difficult to send out relatively soft and comfortable air. Therefore, the embodiment of the present disclosure can set a first corrected speed lower than the first target speed to greatly reduce the air outlet speed of the air conditioner, so as to avoid the unsoftened heat exchange air blowing towards the user quickly and causing discomfort to the user, and thus is beneficial to ensuring the user's comfort.

[0091] Specifically, the processor determines the first corrected speed of the internal fan according to the gear of the uniform air distribution mode, including: when the uniform air distribution mode is the first gear of uniform air distribution, determining the first corrected speed of the internal fan to be 800 r / min; or, when the uniform air distribution mode is the second gear of uniform air distribution, determining the first corrected speed of the internal fan to be 900 r / min; or, when the uniform air distribution mode is the third gear of uniform air distribution, the first corrected speed of the internal fan is 1000 r / min. In this way, when the uniform air distribution effect is poor, the actual air output of the air conditioner is mainly the heat exchange air in the air duct. Therefore, the internal fan is controlled to operate at a smaller first corrected speed, so as to avoid the unsoftened heat exchange air blowing towards the user quickly and causing discomfort to the user by reducing the air output speed of the air conditioner. Therefore, it is beneficial to ensure the comfort of the user. When the uniform air distribution effect is good, the air conditioner can send out soft air that is cool but not cold and warm but not dry, and then the internal fan is controlled to operate at a larger first corrected speed, which is beneficial to better ensure the uniform air distribution effect and improve the comfort of the user.

[0092] Based on the above air conditioner, combined with Figure 7 As shown, another control method for an air conditioner provided by an embodiment of the present disclosure includes:

[0093] S201, the processor responds to the instruction of the air supply mode and controls the connecting arm to rotate to the second preset position.

[0094] S202, the processor controls the uniform air distribution plate to rotate to the second target position so that the uniform air distribution surface of the uniform air distribution plate is located on the extended air outlet surface of the air duct.

[0095] By using the control method for an air conditioner provided by an embodiment of the present disclosure, when the user has an air supply demand, the air conditioner responds to the instruction of the air supply mode, controls the connecting arm to rotate to the second preset position, and controls the uniform air distribution plate to rotate to the second target position so that the uniform air distribution surface of the uniform air distribution plate is located on the extended air outlet surface of the air duct. Thus, the uniform air distribution surface of the uniform air distribution plate in the embodiment of the present disclosure can be used as an extension of the air duct, so as to increase the effective air supply distance of the air conditioner, and further achieve the best air supply effect, which is beneficial to improving the comfort of the user.

[0096] Optionally, the instruction of the air supply mode includes one or more of a start instruction, a gear instruction, a swing instruction, and a close instruction. Among them, the start instruction is used to control the air conditioner to enter the air supply mode. The gear instruction is used to control the air conditioner to switch to the corresponding gear of the air supply mode. The swing instruction is used to control the air conditioner to swing the air output in the air supply mode. The close instruction is used to control the air conditioner to exit the air supply mode. In this way, precise control of the air supply mode can be achieved through the above instructions.

[0097] Optionally, combined with Figure 4As shown, when the connecting arm is in the second preset position, the straight line segment of the connecting arm facing the air equalizing plate is lower than the straight line segment of the connecting arm away from the air equalizing plate, and the angle between the straight line segment of the connecting arm and the horizontal plane is b2.

[0098] Optionally, in combination with Figure 4 As shown, when the air equalizing plate is in the second target position, the air equalizing surface of the air equalizing plate is on the extended air outlet surface of the air duct. The vertical distance between the trailing edge of the air equalizing plate and the bottom case of the indoor unit is h2. The leading edge of the air equalizing plate is lower than the trailing edge of the air equalizing plate, and the angle between the air equalizing surface of the air equalizing plate and the horizontal plane is a2.

[0099] Optionally, after the processor controls the air equalizing plate to rotate to the second target position so that the air equalizing surface of the air equalizing plate is on the extended air outlet surface of the air duct, it further includes: the processor responds to the gear position instruction, and determines the second compensation position of the air equalizing plate according to the gear position of the air supply mode; the processor controls the air equalizing plate to rotate to the second compensation position to maintain or increase the vertical distance between the trailing edge of the air equalizing plate and the bottom case of the indoor unit. In this way, when it is recognized that there is also a gear position instruction, the embodiments of the present disclosure can control the air equalizing plate to rotate from the second target position to the corresponding second compensation position according to the gear position of the air supply mode, so as to adaptively adjust the effective air supply distance of the air conditioner, thereby being able to reasonably match the air supply effect required by the user and being beneficial to improving the comfort of the user.

[0100] Optionally, the gear position of the air supply mode is negatively correlated with the angle between the second compensation position and the second target position. That is, in the air supply mode, the smaller the gear position, the larger the angle between the corresponding second compensation position and the second target position. In this way, when the user's air supply demand is relatively weak, it may not be necessary for the air conditioner to achieve a long-distance air supply. Therefore, the embodiments of the present disclosure can set a second compensation position with a larger angle relative to the second target position to greatly increase the vertical distance between the trailing edge of the air equalizing plate and the bottom case of the indoor unit, so as to be able to reduce the effective air supply distance of the air conditioner and enable the air conditioner to achieve comfortable air supply at a short distance, thereby being able to meet the air supply effect required by the user and being beneficial to improving the comfort of the user.

[0101] Optionally, the gears of the air supply mode include first - gear air supply, second - gear air supply, and third - gear air supply. Among them, the air supply distance of the first - gear air supply is less than that of the second - gear air supply, and the air supply distance of the second - gear air supply is less than that of the third - gear air supply. In this way, the effective air supply distances corresponding to each gear are different. When the air supply mode is the first - gear air supply, the part of the air - distributing plate facing the front edge is lifted significantly, and at this time, the effective air supply distance of the air conditioner is significantly reduced, so as to meet the user's short - distance air supply demand. When the air supply mode is the second - gear air supply, the part of the air - distributing plate facing the front edge is lifted moderately, and at this time, the effective air supply distance of the air conditioner is slightly reduced, so as to meet the user's medium - distance air supply demand. When the air supply mode is the third - gear air supply, the part of the air - distributing plate facing the front edge is lifted slightly or not lifted, and at this time, the air - distributing surface of the air - distributing plate can be used as an extension of the air duct, so that the effective air supply distance of the air conditioner remains at a relatively large level, so as to meet the user's long - distance air supply demand, and further achieve the best air supply effect, which is beneficial to improving the user's comfort level.

[0102] Optionally, the processor determines the second compensation position of the air - distributing plate according to the gear of the air supply mode, including: in the case where the air supply mode is the first - gear air supply, determining that the angle between the second compensation position of the air - distributing plate and the second target position is the fourth angle; or, in the case where the air supply mode is the second - gear air supply, determining that the angle between the second compensation position of the air - distributing plate and the second target position is the fifth angle; or, in the case where the air supply mode is the third - gear air supply, determining that the angle between the second compensation position of the air - distributing plate and the second target position is the sixth angle. Among them, the fourth angle is greater than the fifth angle, and the fifth angle is greater than the sixth angle.

[0103] In this way, when the air supply mode is the first - gear air supply, the embodiments of the present disclosure can make the air - distributing plate rotate a relatively larger fourth angle based on the second target position, thereby significantly increasing the vertical distance between the trailing edge of the air - distributing plate and the bottom case of the indoor unit, so that the part of the air - distributing plate facing the front edge is lifted significantly, and at this time, the effective air supply distance of the air conditioner is significantly reduced, so as to meet the user's short - distance air supply demand. When the air supply mode is the second - gear air supply, the embodiments of the present disclosure can make the air - distributing plate rotate a slightly larger fifth angle based on the second target position, thereby appropriately increasing the vertical distance between the trailing edge of the air - distributing plate and the bottom case of the indoor unit, so that the part of the air - distributing plate facing the front edge is lifted moderately, and at this time, the effective air supply distance of the air conditioner is slightly reduced, so as to meet the user's medium - distance air supply demand. When the air supply mode is the third - gear air supply, the embodiments of the present disclosure can make the air - distributing plate rotate a very small sixth angle based on the second target position, or not rotate to remain at the second target position, so that the air - distributing surface of the air - distributing plate can be used as an extension of the air duct, so that the effective air supply distance of the air conditioner remains at a relatively large level, so as to meet the user's long - distance air supply demand, and further achieve the best air supply effect, which is beneficial to improving the user's comfort level.

[0104] Preferably, the fourth angle is 20°. At this time, the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit is 23 mm. The effective air supply distance of the air conditioner is relatively small, which can meet the user's short-distance air supply requirements. The fourth angle can also be adjusted according to the actual needs of the user, and can also be set to other reasonable values such as 18° or 22°.

[0105] Preferably, the fifth angle is 10°. At this time, the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit is 13 mm. The effective air supply distance of the air conditioner is medium, which can meet the user's medium-distance air supply requirements. The fifth angle can also be adjusted according to the actual needs of the user, and can also be set to other reasonable values such as 8° or 12°.

[0106] Preferably, the sixth angle is 0°. At this time, the vertical distance between the trailing edge of the air distribution plate and the bottom case of the indoor unit is 3 mm. The effective air supply distance of the air conditioner is relatively large, which can meet the user's long-distance air supply requirements. The sixth angle can also be adjusted according to the actual needs of the user, and can also be set to other reasonable values such as 1° or 2°.

[0107] Optionally, the air supply mode in the embodiments of the present disclosure may further include more gears, not limited to the above three gears. The working positions of the air distribution plate, the connecting arm and the air guide plate can be reasonably set according to the various gears of the above air supply mode, which will not be listed one by one here. At the same time, based on the various gears of the above air supply mode, the air conditioner can make corresponding function adjustments to match the air supply distance required by the user, thereby improving the comfort of the user.

[0108] Optionally, after the processor controls the air distribution plate to rotate to the second target position so that the air distribution surface of the air distribution plate is located on the air outlet extension surface of the air duct, it further includes: the processor responds to the swing instruction and controls the air distribution plate to periodically rotate within the second angle range with the second target position as the limit position. In this way, when it is recognized that there is also a swing instruction, the embodiments of the present disclosure can control the air distribution plate to periodically rotate within the second angle range with the second target position as the limit position, so as to realize the swing air supply in the air supply mode and avoid discomfort caused by long-term direct blowing to the user.

[0109] Optionally, the second angle range can be set in combination with the difference between the indoor ambient temperature and the air conditioner set temperature. Preferably, the second angle range can be set to [0°, 10°] to control the uniform air distribution plate to rotate periodically with the second target position as the upper limit position. It should be understood that the second angle range refers to the set of included angles between the multiple positions where the uniform air distribution plate rotates periodically and the second target position. For example, when the uniform air distribution plate swings to the second target position, the included angle is 0°. The reason for setting the second target position as the upper limit position here is to prevent the uniform air distribution plate from interfering with the bottom case of the indoor unit when it swings further upward, thus ensuring the reliability of the swinging air supply of the air conditioner. Further, when the absolute value of the difference between the indoor ambient temperature and the air conditioner set temperature is greater than the third preset temperature difference, the second angle range can be appropriately reduced, for example, adjusted to [0°, 5°], so that the actual air supply distance of the air conditioner is relatively stable, which is beneficial to the concentrated air supply to the area where the user is located, and thus can reasonably optimize the air supply effect when the indoor temperature difference is large to avoid the user's unclear cold and heat feelings caused by overly scattered air supply. The second angle range can also be adjusted according to the actual needs of the user and can be set to any other reasonable range.

[0110] Optionally, after the processor responds to the instruction of the air supply mode, it further includes: the processor controls the air deflector to rotate to the target air deflector position so that the air deflector surface is parallel to the extended air outlet surface of the air duct. In this way, when receiving the instruction of the air supply mode, the embodiment of the present disclosure controls the air deflector to rotate to the target air deflector position, thereby being able to reasonably guide the air outlet direction of the heat exchange air in the air duct. By making the air deflector surface parallel to the extended air outlet surface of the air duct, the embodiment of the present disclosure can increase the air supply distance of the air conditioner to achieve a better air supply effect, which is beneficial to improving the comfort of the user.

[0111] Optionally, in combination with Figure 4 As shown, when the air deflector is in the target air deflector position, the leading edge of the air deflector is lower than the trailing edge of the air deflector, and the included angle between the air deflector surface and the horizontal plane is c2.

[0112] Optionally, after the processor controls the air deflector to rotate to the target air deflector position so that the air deflector surface is parallel to the extended air outlet surface of the air duct, it further includes: the processor responds to the swing instruction and controls the air deflector to rotate periodically within the fourth angle range with the target air deflector position as the limit position. In this way, when it is recognized that there is also a swing instruction, the embodiment of the present disclosure can control the air deflector to rotate periodically within the fourth angle range with the target air deflector position as the limit position, thereby being able to achieve the swinging air deflection in the air supply mode to avoid discomfort caused by long-term direct blowing to the user. Furthermore, it can cooperate with the swing of the uniform air distribution plate to simultaneously send out a more uniform swinging air to better improve the comfort of the user.

[0113] Optionally, the fourth angular range can be set in combination with the difference between the indoor ambient temperature and the air conditioner set temperature. Preferably, the fourth angular range can be set to [0°, 10°] to control the periodic rotation of the air deflector with the target air deflector position as the upper limit position. It should be understood that the fourth angular range refers to the set of included angles between the multiple positions of the periodic rotation of the air deflector and the target air deflector position respectively. For example, when the air deflector swings to the target air deflector position, the included angle is 0°. Further, when the absolute value of the difference between the indoor ambient temperature and the air conditioner set temperature is greater than the fourth preset temperature difference, the fourth angular range can be appropriately reduced, for example, adjusted to [0°, 5°], so that the actual air supply distance of the air conditioner is relatively stable, which is beneficial to the concentrated air supply to the area where the user is located, and thus can reasonably optimize the air supply effect when the indoor temperature difference is large to avoid the user's unclear hot and cold feelings caused by overly scattered air supply. The fourth angular range can also be adjusted according to the actual needs of the user and can also be set to any other reasonable range.

[0114] Optionally, after responding to the instruction of the air supply mode, it further includes: the processor controls the internal fan to operate at the second target speed. In this way, when receiving the instruction of the air supply mode, the embodiment of the present disclosure controls the internal fan to operate at the second target speed, so as to be able to reasonably set the air outlet speed of the air conditioner to match the current air supply mode, which is beneficial to better ensuring the air supply effect and improving the comfort of the user.

[0115] Preferably, the second target speed is 1900 r / min to correspond to the air supply mode of the air conditioner, so as to be able to meet the user's long-distance air supply requirements. The second target speed can also be adjusted in combination with the gear instruction of the air supply mode and can also be set to other reasonable values such as 1700 r / min or 1500 r / min.

[0116] Optionally, after the processor controls the internal fan to operate at the second target speed, it further includes: the processor responds to the gear instruction and determines the second corrected speed of the internal fan according to the gear of the air supply mode; the processor controls the internal fan to operate at the second corrected speed. Among them, the second corrected speed is less than or equal to the second target speed. In this way, when it is recognized that there is also a gear instruction, the embodiment of the present disclosure can determine the corresponding second corrected speed according to the gear of the air supply mode and control the speed of the internal fan to decrease from the second target speed to the second corrected speed to adaptively adjust the air outlet speed of the air conditioner, so as to be able to reasonably match the actual air supply effect of the air conditioner and is beneficial to ensuring the comfort of the user.

[0117] Optionally, the gear of the air supply mode is negatively correlated with the rotational speed difference between the second target rotational speed and the second corrected rotational speed. That is, in the air supply mode, the smaller the gear, the larger the rotational speed difference between the corresponding second target rotational speed and the second corrected rotational speed. In this way, when the gear of the air supply mode is small, the actual air supply distance of the air conditioner is small. Since it is applied to short-distance air supply, the wind speed decreasing effect is not obvious at this time. Therefore, the wind speed felt by the user is close to the wind speed at the air outlet. Therefore, the second corrected rotational speed lower than the second target rotational speed can be set in the embodiments of the present disclosure to significantly reduce the air outlet wind speed of the air conditioner, so as to avoid discomfort caused by excessive air outlet wind speed to the user, and thus is beneficial to ensuring the comfort of the user.

[0118] Specifically, the processor determines the second corrected rotational speed of the internal fan according to the gear of the air supply mode, including: when the air supply mode is the first gear air supply, determining that the second corrected rotational speed of the internal fan is 1500 r / min; or, when the air supply mode is the second gear air supply, determining that the second corrected rotational speed of the internal fan is 1700 r / min; or, when the air supply mode is the third gear air supply, the second corrected rotational speed of the internal fan is 1900 r / min. In this way, when the air supply is at a short distance, the wind speed decreasing effect is not obvious, and the wind speed felt by the user is close to the wind speed at the air outlet. Therefore, the internal fan is controlled to operate at a smaller second corrected rotational speed, so as to appropriately reduce the air outlet wind speed of the air conditioner, avoid discomfort caused by excessive air outlet wind speed to the user, and thus is beneficial to ensuring the comfort of the user. When the air supply is at a long distance, the wind speed decreasing effect is more obvious, and the wind speed felt by the user is quite different from the wind speed at the air outlet. Therefore, the internal fan is controlled to operate at a larger second corrected rotational speed, so as to better meet the user's long-distance air supply requirement, avoid the wind speed after decrease being too small to cause the user to feel obvious cold or heat, and thus is beneficial to improving the comfort of the user.
