[0023] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0025] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The main solution of this application embodiment is: based on an indoor unit provided with a side air outlet and a bottom air outlet, a control method is proposed, wherein the indoor unit includes an air outlet assembly, the air outlet assembly is configured to adjust the air outlet state of the side air outlet and the bottom air outlet, and the control method of the indoor unit includes: in response to a shutdown command, controlling the air outlet assembly to operate in a first position state, the first position state being configured to open the side air outlet and close the bottom air outlet.

[0027] In this embodiment, for ease of description, the indoor unit will be used as the subject of the explanation.

[0028] Because of the limitations of the single air outlet of the indoor unit in the relevant technologies, it is difficult to meet the diverse air supply needs.

[0029] This application provides the above-mentioned solution, based on an indoor unit equipped with side air outlets and a bottom air outlet. The coordinated arrangement of the side air outlets and the bottom air outlets helps to meet diverse air supply needs. When a shutdown command is received, regardless of the position of the air supply component, it resets to the preset position. On the one hand, this ensures that the air outlet is closed when the user looks up at the indoor unit, making the indoor unit's shutdown status visible. On the other hand, when the indoor unit is turned on again, it uses the first position as the initial position for air supply component position control, which can improve the accuracy and efficiency of air supply component position control.

[0030] This application discloses an environmental control device and an indoor unit 200 applied to the environmental control device. The environmental control device is configured to regulate the air in an indoor environment. The environmental control device may include an air conditioner, etc., and the air conditioner is configured to regulate the air in an indoor environment.

[0031] In this embodiment, refer to Figures 1 to 4 The environmental control equipment includes an indoor unit 200 and an outdoor unit, and the indoor unit 200 includes at least two air outlets. In this embodiment, the different air outlets have different orientations and different air resistances.

[0032] In this embodiment, the indoor unit 200 is a ducted air conditioner. The installation height of the indoor unit 200 is higher than the height of a person.

[0033] The indoor unit 200 is equipped with an indoor air duct, and at least two air outlets are connected to the indoor air duct. An indoor heat exchanger 21 and an indoor fan 22 are installed in the indoor air duct. The indoor fan 22 can drive indoor air into the indoor air duct to exchange heat with the indoor heat exchanger 21 and then send it into the room from at least one air outlet.

[0034] In this embodiment, at least two air outlets include a side air outlet 201 located on the side and a bottom air outlet 202 located on the bottom. The indoor unit 200 includes a housing, which comprises a top plate, a bottom plate, and side plates. The top plate and the bottom plate are spaced apart vertically. The top plate is connected to the upper end of the side plate, and the bottom plate is connected to the lower end of the side plate. The bottom plate has the bottom air outlet 202, and the side plates have the side air outlets 201. Both the bottom air outlet 202 and the side air outlets 201 are connected to the indoor air duct.

[0035] The base plate is the plate located at the bottom of the casing when the indoor unit 200 is installed in the indoor space, and the side plate is the plate on the casing adjacent to the base plate. When the indoor unit 200 is installed in the indoor space, the angle between the side plate and the wall of the indoor space (e.g., 0 degrees) is smaller than the angle between the base plate and the wall of the indoor space (e.g., 90 degrees).

[0036] The air outlet surface of the lower air outlet 202 intersects with the air outlet surface of the side air outlet 201. Without the guidance of an air guiding component, the air outlet direction of the lower air outlet 202 is downward (vertically downward or at an angle less than or equal to 45° with the vertical direction), and the air outlet direction of the side air outlet 201 is horizontal (along the horizontal direction or at an angle less than or equal to 45° with the horizontal direction). In this embodiment, the air outlet surface of the lower air outlet 202 is perpendicular to the air outlet surface of the side air outlet 201.

[0037] Without the assistance of air guiding components during the operation of the indoor fan 22, the air resistance when the air in the indoor duct exits from the lower air outlet 202 is greater than the air resistance when the air in the indoor duct exits from the side air outlet 201. In other words, when the indoor fan 22 rotates at the same speed, the air volume exiting from the lower air outlet 202 is less than the air volume exiting from the side air outlet 201. In this embodiment, the area of ​​the lower air outlet 202 is smaller than the area of ​​the side air outlet 201, and the angle between the air outlet direction of the indoor fan 22 and the air outlet surface of the side air outlet 201 is greater than the angle between the air outlet direction and the air outlet surface of the lower air outlet 202. That is, the air outlet direction of the indoor fan 22 is towards the side air outlet 201 and not towards the lower air outlet 202.

[0038] When the indoor unit 200 discharges air through the lower air outlet 202, the discharged air can not only regulate the air temperature of the indoor space, but also regulate the temperature of the indoor space's enclosure structure.

[0039] In other embodiments, at least two air outlets may be located on the side of the indoor unit 200, or the air outlets may have the same air outlet direction.

[0040] In this embodiment, the indoor unit 200 further includes an air outlet assembly 23, which is configured to adjust the air outlet state of the at least two air outlets, and can adjust the opening and / or closing of each air outlet and / or adjust the air volume.

[0041] The air outlet assembly 23 can be a single, integral structure or composed of more than one switch door. When the air outlet assembly 23 includes more than one switch door, the air outlet can correspond one-to-one with the switch door, and each switch door can adjust the air outlet state of its corresponding air outlet; or, some switch doors can simultaneously adjust the air outlet state of different air outlets.

[0042] In this embodiment, an air outlet assembly 23 is installed in the indoor air duct. The position of the air outlet assembly 23 can be changed to allow the lower air outlet 202 and the side air outlet 201 to cooperate in different air outlet states: Reference Figure 1 (a) The dashed line indicates the airflow direction. When the air outlet assembly 23 is in the first position, the lower air outlet 202 is open and the side air outlet 201 is closed. Reference Figure 1(b) The dashed line indicates the airflow direction. When the air outlet assembly 23 is in the second or fifth position, the lower air outlet 202 is closed and the side air outlet 201 is open. Reference Figure 1 (c) and Figure 1 (d) The dashed line indicates the airflow direction. When the air outlet assembly 23 is in the third or fourth position, both the lower air outlet 202 and the side air outlet 201 are open.

[0043] In this embodiment, the air outlet assembly 23 includes a first switch door 231 and a second switch door 232. Both the first switch door 231 and the second switch door 232 are located inside the indoor unit 200. The side air outlet 201 includes a first air outlet area and a second air outlet area. The first switch door 231 is configured to adjust the air volume of the first air outlet area, and the second switch door 232 is configured to adjust the air volume of the second air outlet area and the lower air outlet 202.

[0044] In this embodiment, the first air outlet area is the upper air outlet area away from the lower air outlet 202, and the second air outlet area is the lower air outlet area close to the lower air outlet 202. The first switch door 231 is rotatably installed on the upper side of the side air outlet 201, which can adjust the air volume of the upper air outlet area. The second switch door 232 is rotatably installed at the adjacent position between the lower air outlet 202 and the side air outlet 201. When the second switch door 232 rotates, it can simultaneously adjust the air volume of the lower air outlet area and the lower air outlet 202. The installation position of the first switch door 231 is closer to the top plate, and the installation position of the second switch door 232 is closer to the bottom plate.

[0045] Reference Figure 1 (a) The first position includes the first switch door 231 being in the first position and the second switch door 232 being in the second position. Both the first switch door 231 and the second switch door 232 are in the windproof position. The first switch door 231 blocks the first air outlet area, and the second switch door 232 blocks the second air outlet area. That is, the angle between the panel of the two switches and the air outlet direction of the indoor fan 22 is greater than the preset angle. The first switch door 231 and the second switch door 232 cooperate to block the side air outlet 201 and open the lower air outlet 202. The air outlet of the indoor fan 22 is blown into the room from the lower air outlet 202 under the combined guiding effect of the first switch door 231 and the second switch door 232, and stops blowing into the room from the side air outlet 201.

[0046] Reference Figure 1(b) The second position includes the first switch door 231 being in the third position and the second switch door 232 being in the fourth position. In the third position, the angle between the surface of the first switch door 231 and the air outlet direction of the indoor fan 22 is less than or equal to a preset angle (e.g., the surface of the first switch door 231 is parallel to the air outlet direction of the indoor fan 22), and the first switch door 231 opens the first air outlet area. In the fourth position, the angle between the surface of the second switch door 232 and the air outlet direction of the indoor fan 22 is less than or equal to a preset angle, and the second switch door 232 blocks the lower air outlet 202 and opens the second air outlet area. The first switch door 231 and the second switch door 232 cooperate to open the side air outlet 201, and the air from the indoor fan 22 is blown into the room from the side air outlet 201 under the combined guiding effect of the first switch door 231 and the second switch door 232, and stops blowing into the room from the lower air outlet 202. In some other implementations, the third position may also be the position that blocks the first air outlet area.

[0047] Reference Figure 1 (d) The third position includes the first switch door 231 being in the third position and the second switch door 232 being in the fifth position. The fifth position is located between the second position and the fourth position. In the fifth position, the second switch door 232 simultaneously opens the second air outlet area and the lower air outlet 202. At this time, the side air outlet 201 is fully opened. The air from the indoor fan 22 is blown into the room from the lower air outlet 202 and the side air outlet 201 respectively under the combined guiding effect of the first switch door 231 and the second switch door 232.

[0048] Reference Figure 1 (c) The fourth position state may include the first switch door 231 being in the third position and the second switch door 232 being in the second position, at which time the side air outlet 201 is partially open and partially blocked. The first switch door 231 and the second switch door 232 cooperate to open the lower air outlet 202 and the side air outlet 201, and the air outlet of the indoor fan 22 is blown into the room from the lower air outlet 202 and the side air outlet 201 respectively under the combined air guiding effect of the first switch door 231 and the second switch door 232.

[0049] Reference Figure 1 (e) The fifth position state may include the first switch door 231 being in the first position and the second switch door 232 being in the fourth position. At this time, the side air outlet 201 is partially open and partially blocked, and the lower air outlet 202 is closed. Then, the air outlet of the indoor fan 22 is blown into the room from the second air outlet area of ​​the side air outlet 201 under the combined air guiding effect of the first switch door 231 and the second switch door 232, and the indoor unit 200 is in the low wind mode.

[0050] Among them, combined Figure 3 When the first door 231 is in the third position, it abuts against the top plate, and when the second door 232 is in the fourth position, it abuts against the bottom plate.

[0051] It can be seen that by changing the position of the air outlet component 23, the indoor unit 200 can have at least five different air outlet modes.

[0052] In other embodiments, the air outlet assembly 23 may also include a third switch door rotatably mounted between the lower air outlet 202 and the side air outlet 201. The third switch door can switch between a first operating device, a second operating position, and a third operating position. The first operating position is the position where the lower air outlet 202 is closed and the side air outlet 201 is open. The second operating position is the position where the side air outlet 201 is closed and the lower air outlet 202 is open. The third operating position is the position where both the lower air outlet 202 and the side air outlet 201 are open simultaneously.

[0053] In one embodiment, the drive motors for the first switch door 231 and the second switch door 232 are both stepper motors. The control device 100 can control the rotation angle of the corresponding switch door by inputting pulse current to the drive motors. The rotation ratios of the two switch door drive motors are the same; that is, when the control device 100 inputs the same number of pulse currents to the two switch door drive motors, the rotation angles of the first switch door 231 and the second switch door 232 are the same.

Compared with the prior art, the beneficial effects of the environmental control device and indoor unit provided in this application are the same as those of the indoor unit control method provided in the following embodiments, and other technical features in this environmental control device are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0076] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or environmental control device capable of performing the above functions. The following description uses an environmental control device as an example to illustrate this embodiment and the subsequent embodiments.

[0077] Based on this, the embodiments of this application provide a control method for an indoor unit, referring to... Figure 5 , Figure 5 This is a flowchart illustrating the first embodiment of the control method for the indoor unit of this application.

[0078] In this embodiment, the indoor unit is provided with a side air outlet and a bottom air outlet. The indoor unit includes an air outlet assembly, which is configured to adjust the air outlet status of the side air outlet and the bottom air outlet. The control method of the indoor unit includes step S10: Step S10: In response to the power-off command, control the air outlet assembly to operate in a preset position state, wherein the preset position state is set to open the side air outlet and close the lower air outlet.

[0079] The shutdown command can be sent by the user or generated when the indoor unit runs until the shutdown conditions are met.

[0080] When a shutdown command is received, if the air outlet component is in a preset position, the air outlet component will maintain the preset position. If the air outlet component is in a position other than the preset position when a shutdown command is received, the air outlet component will switch from the other position to the preset position.

[0081] In the preset position state, the air outlet component abuts against the fixed structural component on the indoor unit.

[0082] In this embodiment, the air outlet assembly includes the first and second opening / closing doors described above. The preset position state is the second position state described above, which includes the first opening / closing door being in a third position and the second opening / closing door being in a fourth position. Specifically, when the first opening / closing door is in the third position, it is configured to abut against a first structural member of the indoor unit; when the second opening / closing door is in the fourth position, it is configured to abut against a second structural member of the indoor unit.

[0083] The first switch door is rotatably installed on the indoor unit via a rotating shaft. The end of the first switch door opposite to the rotating shaft is a movable end. The first switch door abuts against the first structural member, including the movable end of the first switch door abutting against the first structural member. The second switch door is rotatably installed on the indoor unit via a rotating shaft. The end of the second switch door opposite to the rotating shaft is a movable end. The second switch door abuts against the second structural member, including the movable end of the second switch door abutting against the first structural member.

[0084] It should be noted that the first structural component and the second structural component here are both fixed structural components (i.e., non-moving components) other than the first and second opening and closing doors.

[0085] The second position state here is the most stable position state among all the allowed operating positions of the air outlet assembly, with both doors abutting against the fixed structure; in other position states of the air outlet assembly, at least one of the first and second doors is not abutting against the fixed structure.

[0086] This embodiment provides a control method for an indoor unit. Based on an indoor unit equipped with side and bottom air outlets, the coordinated arrangement of the side and bottom air outlets helps to meet diverse air supply needs. Upon receiving a shutdown command, regardless of the position of the air supply component, it resets to a preset position. This ensures that the air outlets are closed when the user looks up at the indoor unit, making the shutdown status visible. Furthermore, the next time the indoor unit is turned on, it uses the first position as the initial position for air supply component position control, improving the accuracy and efficiency of air supply component position control. Specifically, when both the first and second doors are abutting against their corresponding structural components in the preset position, unnecessary displacement of the air supply component during shutdown is reduced. In particular, the moving ends of the first and / or second doors do not experience unnecessary movement, which improves the stability of the air supply component's position during shutdown and ensures the accuracy of the initial position upon subsequent startup. This allows the air supply component to accurately switch to the desired target position based on its initial position.

[0087] In other embodiments, the air outlet assembly may also include the aforementioned third switch door, which controls the opening and closing states of the side air outlet and the lower air outlet through a switch door. The preset position states here include the aforementioned first operating position.

[0088] In one feasible implementation, when the air outlet assembly includes the aforementioned first and second opening / closing doors, the indoor unit includes a top plate, a bottom plate, and a side plate. The top plate and the bottom plate are spaced apart in the vertical direction. The top plate is connected to the upper end of the side plate, and the bottom plate is connected to the lower end of the side plate. The side air outlet is located on the side plate, and the lower air outlet is located on the bottom plate. The first structural component includes the top plate, and the second structural component includes the bottom plate.

[0089] The top and / or bottom plate here can be a flat plate structure, or a structure with grooves or protrusions on the flat plate base to cooperate with the opening and closing of the door.

[0090] Based on this, in the preset position state, the first switch door can be limited to the top plate, and the second switch door can be limited to the bottom plate, thereby effectively improving the structural stability of the air outlet assembly in the shutdown state.

[0091] In one feasible implementation, the preset position state includes the first switch door being in a third position and the second switch door being in a fourth position. When the first switch door is in the third position, it is configured to abut against a first structural component of the indoor unit, and when the second switch door is in the fourth position, it is configured to abut against a second structural component of the indoor unit. The step of controlling the air outlet assembly to operate in the preset position state includes: When the first switch door is in the third position, control the first switch door to rotate toward the first structural member; When the second switch door is in the fourth position, control the second switch door to rotate toward the second structural member.

[0092] The rotation of the first door toward the first structural member and the rotation of the second door toward the second structural member can be performed simultaneously or sequentially, and the order of execution is not limited.

[0093] In this scenario, the first switch door is in the third position, and the second switch door is in the fourth position. This is determined by obtaining the drive parameters of the corresponding drive motors for the first and second switches door. Due to wear of the drive motors and resistance encountered when the air outlet assembly switches positions, the position of the first switch door determined by the drive parameters may deviate from its actual position. Similarly, the position of the second switch door determined by the drive parameters may deviate from its actual position. Therefore, when the first switch door is in the third position, the following two situations may occur in the actual scenario: the actual position of the first switch door is abutting against the first structural component, or the actual position of the first switch door is spaced apart from the first structural component. When the second switch door is in the third position, the following two situations may occur in the actual scenario: the actual position of the second switch door is abutting against the second structural component, or the actual position of the second switch door is spaced apart from the second structural component.

[0094] When a shutdown command is received, if the first switch door is in the third position, the first switch door can be directly controlled to rotate toward the first structural member; if the first switch door is in a position other than the third position, the first switch door can be controlled to switch from the current position to the third position, and then the first switch door can be controlled to rotate toward the first structural member.

[0095] When a shutdown command is received, if the second switch door is in the fourth position, the second switch door can be directly controlled to rotate toward the second structural component; if the second switch door is in a position other than the fourth position, the second switch door can be controlled to switch from the current position to the fourth position before rotating toward the second structural component.

[0096] The step of controlling the first switch door to rotate toward the first structural member includes: controlling the first switch door to rotate toward the first structural member by a first angle, or controlling the first switch door to maintain rotation toward the first structural member for a first duration.

[0097] The step of controlling the second switch door to rotate toward the second structural member includes: controlling the second switch door to rotate toward the second structural member by a second angle or controlling the second switch door to maintain rotation toward the second structural member for a second duration.

[0098] In this embodiment, both the first angle and the second angle are preset fixed angles. In other implementations, the first angle and the second angle can also be determined based on the actual operating conditions of the indoor unit. For example, the first angle and the second angle can be determined based on the number of times the position state of the air outlet component switches during the start-up phase before receiving the stop signal, and / or the initial position state of the air outlet component when receiving the stop signal, and / or the indoor fan speed when the air outlet component switches between the initial position state and the preset position state after receiving the stop signal. The first duration and the second duration can be determined analogously to the first angle and the second angle, and will not be elaborated here.

[0099] In this embodiment, when the air outlet component is in the preset position, the air outlet component continues to rotate toward the fixed structure of the indoor unit. Based on this, the gap between the air outlet component and the fixed structure can be effectively eliminated, ensuring that the actual position of the air outlet component can abut against the fixed structure of the indoor unit. This further improves the positional stability of the air outlet component in the shutdown state, thereby further improving the position switching efficiency and accuracy of the air outlet component when the unit is turned on.

[0100] In one feasible implementation, after the steps of controlling the first switch door to rotate toward the first structural member and the second switch door to rotate toward the second structural member, the method further includes: obtaining the current first real-time position of the first switch door and the current second real-time position of the second switch door; determining the first real-time position as the new third position and the second real-time position as the new fourth position to obtain a new preset position state; and controlling the air outlet assembly to operate according to the new preset position state after the indoor unit is turned on.

[0101] The first real-time position can be determined based on the real-time drive parameters (such as the real-time drive angle) of the drive motor corresponding to the first door opening and closing.

[0102] The second real-time position can be determined based on the real-time drive parameters (such as the real-time drive angle) of the drive motor corresponding to the second door opening / closing.

[0103] After the indoor unit is turned on, controlling the operation of the air outlet component according to the new preset position state may include: after the indoor unit is turned on, determining the first target motor control parameters of the drive motor corresponding to the air outlet component required for the air outlet component to switch from the new preset position state to the first target position state, and controlling the drive motor to drive the air outlet component according to the first target motor control parameters, so that the air outlet component switches from the new preset position state to the first target position state; and / or, after the indoor unit is turned on, determining the second target motor control parameters of the drive motor corresponding to the air outlet component required for the air outlet component to switch from the second target position state to the new preset position state, and controlling the drive motor to drive the air outlet component according to the second target motor control parameters, so that the air outlet component switches from the second target position state to the new preset position state; and / or, after the indoor unit is turned on, executing step S10. Here, the first target position state and the second target position state can be the first position state, the third position state, the fourth position state, or the fifth position state described above. Furthermore, other position states besides the preset position state can be corrected according to the position deviation parameter between the new preset position state and the original preset position state, thereby further achieving precise control of the air outlet component position.

[0104] In this embodiment, the first real-time position after the first switch door rotates toward the first structural member can be considered as the position where the first switch door abuts against the first structural member, and the second real-time position after the second switch door rotates toward the second structural member can be considered as the position where the second switch door abuts against the second structural member. Based on this, the preset position state updated based on the first and second real-time positions can ensure that the indoor unit can accurately control the position of the air outlet component based on the new preset position state after it is turned on, ensuring that the air outlet component accurately reaches the required position state, so as to further ensure that the air outlet of the indoor unit is accurately matched with the needs of the indoor user.

[0105] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 6 Step S10 includes: Step S11: In response to the power-off command, when the air outlet assembly is currently in the first position state, control the first switch door to rotate toward the first structural member to the third position, and control the second switch door to rotate toward the second structural member to the fourth position; wherein, in the first position state, the first switch door blocks the first air outlet area, and the second switch door blocks the second air outlet area and opens the lower air outlet; In this embodiment, the first position state includes the first switch door being in a first position and the second switch door being in a second position. Based on the first and third positions, a first driving parameter for the drive motor corresponding to the first switch door is determined. During the process of controlling the first switch door to rotate toward the first structural member to the third position, the drive motor can be controlled according to the first driving parameter to drive the first switch door to operate, thereby switching the first switch door from the first position to the third position. Based on the second and fourth positions, a second driving parameter for the drive motor corresponding to the second switch door is determined. During the process of controlling the second switch door to rotate toward the second structural member to the fourth position, the drive motor can be controlled according to the second driving parameter to drive the second switch door to operate, thereby switching the second switch door from the second position to the fourth position.

[0106] In this embodiment, the angle between the first position and the third position is a first preset angle, and the angle between the second position and the fourth position is a second preset angle. The steps of controlling the first switch door to rotate toward the first structural member to the third position and controlling the second switch door to rotate toward the second structural member to the fourth position include: controlling the first switch door to rotate toward the first structural member by the first preset angle, and controlling the second switch door to rotate toward the second structural member by the second preset angle. Here, the first driving parameter can be determined based on the first preset angle, and the second driving parameter can be determined based on the second preset angle. The first angle is smaller than the first preset angle described here, and the second angle is smaller than the second preset angle described here.

[0107] Step S12: When the first switch door is in the third position, control the first switch door to rotate toward the first structural member; when the second switch door is in the fourth position, control the second switch door to rotate toward the second structural member.

[0108] In this embodiment, when a shutdown command is received, and the air outlet assembly is in the first position state, the first and second opening and closing doors switch to their respective positions in the preset position states, and then continue to rotate toward their respective fixed structural components. Based on this, it is ensured that the air outlet assembly can be accurately reset to the preset position state of the fixed structural component abutting against the indoor unit when the unit is stopped, thereby improving the structural stability of the air outlet assembly in the shutdown state, as well as improving the accuracy and efficiency of the air outlet assembly position control.

[0109] In one feasible implementation, in the first position state, the first overlapping portion on the first switch door and the second overlapping portion on the second switch door overlap, and the first overlapping portion is located inside the second overlapping portion. The reference direction is from the outside of the indoor unit towards the inside of the indoor unit, and the direction from the second overlapping portion to the first overlapping portion is the first direction, which is the same as the reference direction. Based on this, the steps of controlling the first switch door to rotate toward the first structural member by the first preset angle and controlling the second switch door to rotate toward the second structural member by the second preset angle include: The second switch door is controlled to maintain operation in the second position, and the first switch door is controlled to rotate toward the first structural member by a first starting angle. When the rotation angle of the first switch door reaches the first starting angle, the second switch door is controlled to rotate toward the second structural member by the second preset angle, and the first switch door is controlled to rotate toward the first structural member until the rotation angle reaches the first preset angle; wherein, the first starting angle is less than the first preset angle.

[0110] In this embodiment, the first starting angle is greater than or equal to the reference angle. The reference angle is the minimum angle required for the first opening / closing door to rotate from the first position to the third position while the first overlapping portion and the second overlapping portion are in a separated state during the rotation of the second opening / closing door from the second position to the fourth position.

[0111] The first starting angle can be a preset fixed angle, or it can be determined based on the actual situation of the indoor unit. For example, the first starting angle can be determined based on the current speed of the indoor fan, and the first starting angle is positively correlated with the current speed.

[0112] In this embodiment, the angular velocity of the first door when it rotates is equal to the angular velocity of the second door when it rotates.

[0113] In this embodiment, during the process of the air outlet assembly switching from the first position state to the preset position state, the first switch door first rotates toward the first structural member by a starting angle, and then the second switch door starts to rotate toward the second structural member. Based on this, interference between the first overlapping part and the second overlapping part can be avoided during the position state switching process, ensuring that the first switch door and the second switch door can be accurately switched to the preset position state, while avoiding damage to the switch door.

[0114] Based on any of the above embodiments, in the third embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 7 Step S100 includes: Step S13, in response to the power-off command, when the air outlet assembly is currently in the third position state, control the first switch door to rotate toward the first structural member, and control the second switch door to rotate toward the second structural member to the fourth position. The third position state includes the first switch door being in the third position and the second switch door being in the fifth position. In the third position state, the first switch door opens the first air outlet area, and the second switch door opens the second air outlet area and opens the second air outlet. When a shutdown command is received, the air outlet assembly is in the third position, and the first switch door is in the third position. At this time, the first switch door is directly controlled to rotate toward the first structural member, thereby ensuring that the actual position of the first switch door is in contact with the first structural member. At the same time as the first switch door rotates toward the first structural member, the second switch door is controlled to rotate toward the second structural member to the fourth position.

[0115] In this embodiment, the angle between the fifth position and the fourth position is a third preset angle. The process of controlling the second switch door to rotate toward the second structural member to the fourth position is as follows: controlling the second switch door to rotate toward the second structural member by a second starting angle; controlling the second switch door to rotate toward the second structural member by the third preset angle. In this embodiment, both the second starting angle and the aforementioned second angle are smaller than the third preset angle, and the second starting angle is larger than the second angle. Since the second switch door is in the middle position in the third position state, its movable end is not supported. The force of the fan, etc., can easily cause a deviation between the actual position of the second switch door in the third position state and the fifth position corresponding to the third preset angle. After the second switch door is rotated according to the third preset angle, a large gap will be generated between the actual position of the second switch door and the second structural member, causing the second switch door to be unable to abut against the second structural member. Here, the second switch door first rotates a certain starting angle and then rotates the third preset angle to ensure that the gap between the second switch door and the second structural member is small or even non-existent after the second switch door rotates, thereby ensuring that the second switch door can abut against the second structural member when it continues to rotate toward the second structural member by a second angle.

[0116] Step S14: When the second switch door is in the fourth position, control the second switch door to rotate toward the second structural member.

[0117] In this embodiment, during the process of the air outlet assembly switching from the third position state to the preset position state, the operation of the first and second opening and closing doors is controlled by the above method. This avoids interference between the first and second overlapping parts during the position state switching process, and ensures that the first and second opening and closing doors can be accurately and quickly switched to the preset position state, while also preventing damage to the opening and closing doors.

[0118] In other embodiments, controlling the second switch door to rotate toward the second structural member to the fourth position can also ensure that the second switch door rotates toward the second structural member by a third preset angle.

[0119] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the control method of the indoor unit of this application.
