Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to a zoned air control system, method, and air conditioner. Background Art

[0002] In the prior art, an air conditioner usually has only one air outlet, and the air outlet direction is adjusted within a certain range by the swing of the louver at the air outlet. Taking a wall-mounted air conditioner as an example, a wall-mounted air conditioner is suitable for a small space. A long strip-shaped air outlet is provided at the lower part of the side of the wall-mounted air conditioner, and louvers are installed in the air outlet. The louvers include one or two louvers having the same length as the air outlet. By the swing of the louvers, the air at the air outlet can be swept up and down; taking a cabinet air conditioner as an example, the old model of the cabinet air conditioner usually has a rectangular air outlet at the upper part of the side, and the air is swept up and down by multiple louvers at the air outlet. However, since the cabinet air conditioner is usually applied to a large space, more and more new models of cabinet air conditioners have a larger air outlet size and are arranged circumferentially along the side of the air conditioner to expand the air outlet range of the air outlet, and multiple louvers at the air outlet are designed to swing left and right to achieve left and right air sweeping, which is more suitable for a large space. However, for both the wall-mounted air conditioner and the cabinet air conditioner described above, all the louvers at the air outlet move synchronously, so the air can only be directed to one direction, or the air is swept within the same direction range by the swing of all the louvers. The air sweeping mode is single, especially in a large space or when there are many people in the space, it is difficult to meet the use requirements. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the present invention provides a zoned air control system, method, and air conditioner to solve the problem that all the louvers at the air outlet of the air conditioner in the prior art move synchronously, so the air can only be directed to one direction, or the air is swept within the same direction range by the swing of all the louvers, and the air sweeping mode is single.

[0004] According to an embodiment of the present invention, the following technical solutions are adopted:

[0005] The zoned air control system includes a control component and an execution component. The execution component includes a plurality of air outlets distributed on the air conditioner, multiple groups of louvers respectively corresponding to the air outlets one by one and used to open or close the air outlets, and a plurality of driving members respectively corresponding to the louvers one by one and used to drive the louvers to swing; the control component is used to open and close the driving members. The control component includes a synchronous air sweeping module, an asynchronous air sweeping module, and a unilateral air sweeping module. The synchronous air sweeping module is used to control at least two groups of louvers to swing simultaneously in the same direction. The asynchronous air sweeping module is used to control at least two groups of louvers to swing simultaneously in at least two directions. The unilateral air sweeping module is used to control a single group of louvers or the louvers at a plurality of air outlets opening towards the same side to swing.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] 1. Multiple air outlets are provided. By designing the orientation and position of the air outlets on the air conditioner, the orientation and position of the air flow can be controlled to a certain extent. And through the guidance of the swing blades, the orientation of the air flow is further controlled to expand the range of the air flow. Moreover, users can choose to open only one or several of the air outlets according to their needs, which can meet the users' needs without opening all the air outlets, and reduce the energy consumption of the swing blades to a certain extent.

[0008] 2. Multiple groups of swing blades can be controlled to swing respectively by driving components, so that multiple groups of swing blades can swing in different directions (such as forward rotation or reverse rotation), different swing ranges, different speeds, etc., further expanding the selection of the air-sweeping mode. Synchronous air-sweeping, asynchronous air-sweeping or unilateral air-sweeping can be selected, providing multiple choices for users. Especially for asynchronous air-sweeping, when the swing directions of multiple groups of swing blades are different, that is, when the air-sweeping directions are different, the indoor air can be stirred in multiple directions, so that the cold air or hot air can spread faster in the room, making the indoor temperature more balanced and obtaining better cooling or heating effects.

[0009] Furthermore, the orientation of the air outlet is horizontal or obliquely downward, and an avoidance portion for the end of the swing blade to swing is provided on the inner wall of the air outlet.

[0010] Beneficial effect: By providing the avoidance portion, the end of the swing blade can swing into the air outlet, expanding the range where the swing blade can swing, and further expanding the air guiding range.

[0011] Furthermore, the control component further includes an anti-direct-blowing module, and the anti-direct-blowing module is used to control the swing blade to swing so as to direct the air from the air outlet to be horizontal, upward or downward.

[0012] Beneficial effect: Through the setting of the anti-direct-blowing module, the swing blade is controlled to swing to a specific angle to avoid directly blowing on the human body.

[0013] Furthermore, the control component further includes a power-off memory module.

[0014] Beneficial effect: In the case of air conditioner failure, sudden power outage, shutdown, etc., the power-off memory module memorizes the previous operating state of the swing blade. Then, after the air conditioner is restarted, it can operate according to the previously memorized operating state of the swing blade, meeting the user's usage habits.

[0015] According to the embodiments of the present invention, the following technical solutions are also adopted in the present invention:

[0016] A zoning air control method, using a zoning air control system, the axis of rotation of the swing blade is horizontal, and the swing angles of the swing blade include:

[0017] Angle a: The angle between the line connecting the end point of the swing blade facing outside the air outlet and the rotation center of the swing blade shaft and the vertical line is not greater than 35 degrees; Angle b: The swing blade closes the air outlet; Angle c: The angle between the line connecting the end point of the swing blade facing inside the air outlet and the rotation center of the swing blade shaft and the horizontal line is not greater than 5 degrees; Angle d: The included angle with Angle c is 15 - 25 degrees of positive rotation; Angle e: The included angle with Angle c is 40 - 50 degrees of positive rotation;

[0018] After obtaining the synchronous sweeping signal, at least two groups of swing blades swing simultaneously in the range between Angle a and Angle e in the same direction; after obtaining the asynchronous sweeping signal, at least two groups of swing blades swing simultaneously in at least two directions in the range between Angle a and Angle e; after obtaining the unilateral sweeping signal, a single group of swing blades or the swing blades at multiple air outlets with openings on the same side swing in the range between Angle a and Angle e.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the range between Angle a and Angle e, the swing blade can swing arbitrarily to meet various requirements such as synchronous sweeping, asynchronous sweeping, and unilateral sweeping. Since the axis of the swing blade shaft is in the horizontal direction, the swinging direction of the swing blade is the up and down direction, that is, up and down sweeping. The angular range between Angle a and Angle e is nearly 180 degrees, with a large swinging range, which can meet the requirements of various swinging modes. And after the air conditioner is turned on for a long time, the cold air sinks and the hot air rises, and it is easy to form a state of upper hot and lower cold indoors. The up and down sweeping can balance the temperature up and down in the room.

[0021] Further, when the air conditioner is in the cooling mode, after obtaining the synchronous sweeping signal or the asynchronous sweeping signal or the unilateral sweeping signal, the swing blade swings in the range between Angle c and Angle e.

[0022] Beneficial effect: In the actual use process, when the swinging angle range of the swing blade is large, the generated noise is also large. And in the cooling mode, since the cold air is easy to sink, the sweeping angle for cooling should be selected as the upward angle as much as possible, so the swinging angle range of the swing blade can be reduced.

[0023] Further, when the air conditioner is in the cooling mode, after obtaining the anti-direct-blowing signal, the swing blade swings to Angle c and remains stationary; when the air conditioner is in the heating mode, after obtaining the anti-direct-blowing signal, the swing blade swings to Angle a and remains stationary.

[0024] Beneficial effects: Since cold air tends to sink and hot air tends to rise, when the anti-direct-blow function is activated, it is necessary to consider whether the air conditioner is currently in the cooling mode or the heating mode. In the cooling mode, angle c is the smaller angle at which the swing blade opens and is basically oriented horizontally. Since the air outlet of the air conditioner is generally located at a relatively high position indoors, that is, the cold air is discharged to the upper part of the room after being discharged, and then through the sinking of the cold air, heat exchange in a large area of the room is satisfied. In the heating mode, angle a is the larger angle at which the swing blade opens downward, so that the hot air blows directly downward as much as possible to meet the heating demand in the lower part of the room.

[0025] Furthermore, when the air conditioner is in the cooling mode, after receiving the shutdown signal, it memorizes the current swing angle range, speed, and direction of the swing blade and then shuts down. When the air conditioner is restarted, if the working mode at startup is the cooling mode, the swing blade operates in the memorized state.

[0026] Beneficial effects: Since the cooling mode of the air conditioner is generally more commonly used and users have more diverse needs for cooling, in the cooling mode, the operating state of the swing blade can be memorized when shutting down, and then directly operate in the memorized state later to meet the usage habits of users.

[0027] Furthermore, when the air conditioner is in the heating mode, it obtains the rotation speed of the indoor fan of the air conditioner. When the fan speed is not less than the set value of the air conditioner, the swing blade swings within the range between angle c and angle e; when the fan speed is less than the set value of the air conditioner, the swing blade swings within the range between angle a and angle e.

[0028] Beneficial effects: The rotation speed of the fan is regarded as the wind speed of the air outlet. When the wind speed set by the user is less than the factory set value of the air conditioner itself, it generally means that the wind speed is below the gentle breeze state. In the heating mode, a larger range of agitation is required in the gentle breeze state to make the indoor temperature more uniform, so a larger swing angle range of the swing blade is needed; while when the wind speed is relatively high, a smaller range of swing angles can meet the uniformity of the air flow.

[0029] According to the embodiments of the present invention, the present invention also adopts the following technical solutions:

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings of the specification, and specific implementation modes will be given.

[0039] Embodiment 1

[0040] As Figure 1 shown, an air conditioner includes a zoned air control system. The zoned air control system includes a control component and an execution component. The execution component includes a plurality of air outlets 3 distributed on the housing 1 of the air conditioner, a plurality of groups of swinging blades 2 respectively corresponding to the air outlets 3 one by one and used to open or close the air outlets 3, and a plurality of driving parts respectively corresponding to the swinging blades 2 one by one and used to drive the swinging blades 2 to swing. Specifically, Figure 1 taking a wall-mounted air conditioner as an example, two juxtaposed air outlets 3 along the length direction of the housing 1 are opened in the lower part inside the side surface of the air conditioner housing 1, and there are two groups of swinging blades 2. Taking Figure 1 as an example, each group of swinging blades 2 only includes one swinging blade 2. In the actual design process, multiple swinging blades 2 can also be set to jointly open or close the air outlet 3. In the actual design process, the middle parts of the two air outlets 3 can also be communicated, and only the two groups of swinging blades 2 are used to separate the two communicated air outlets 3. Connecting blocks are fixed at both ends of the swinging blade 2, a rotating shaft 4 is fixed between the two connecting blocks, and the driving part includes a motor for driving the rotating shaft 4 to rotate. Specifically, the motor and the rotating shaft 4 are directly fixedly connected or the motor drives the rotating shaft 4 to rotate through other conventional transmission methods in the prior art.

[0041] The orientation of the air outlet 3 is horizontal or obliquely downward. Taking a wall-mounted air conditioner as an example, since a wall-mounted air conditioner is usually installed on the upper part of an indoor wall, the orientation of the air outlet 3 is preferably obliquely downward. Taking Figure 2Taking the direction shown as an example, the air outlet 3 faces right downward. Correspondingly, taking a floor-standing air conditioner as an example, the orientation of the air outlet 3 is preferably horizontal. The axis of the rotating shaft 4 of the swing blade 2 is horizontal. Since the two air outlets 3 are arranged side by side, the air outlet range is extended in the length direction (i.e., horizontally), so the rotation direction of the swing blade 2 is the up and down direction, and the air outlet direction can be adjusted vertically by sweeping up and down. An avoidance part 5 for the end part of the swing blade 2 to swing is arranged on the inner wall of the air outlet 3, so that the end part of the swing blade 2 can rotate into the air outlet 3, and the rotatable angle of the swing blade 2 is enlarged.

[0042] The control component is used to open and close the driving part. The control component includes a synchronous sweeping module, an asynchronous sweeping module and a unilateral sweeping module. The synchronous sweeping module is used to control at least two groups of swing blades 2 to swing in the same direction at the same time. The asynchronous sweeping module is used to control at least two groups of swing blades 2 to swing in at least two directions at the same time. The unilateral sweeping module is used to control a single group of swing blades 2 or the swing blades 2 at multiple air outlets 3 opening towards the same side to swing.

[0043] Specifically, the control component includes a controller applied to an air conditioner in the prior art. The controller is signal-connected to the motor. The synchronous sweeping module includes a synchronous sweeping signal transmitting part and a synchronous sweeping signal receiving part. Specifically, the control of an air conditioner in the prior art is generally realized by remote control or control buttons arranged on the air conditioner. The synchronous sweeping signal transmitting part can be a synchronous sweeping button arranged on the remote control or a synchronous sweeping button arranged on the air conditioner (hereinafter, the synchronous sweeping signal transmitting circuit arranged on the remote control chip is taken as an example for description). The synchronous sweeping signal receiving part is a synchronous sweeping signal receiving circuit arranged on the controller. That is, after the synchronous sweeping signal receiving circuit in the controller receives the synchronous sweeping signal sent by the remote control, the signal output end of the controller controls the motors corresponding to the two groups of swing blades 2 to start synchronously and rotate in the same direction to complete synchronous sweeping.

[0044] Correspondingly, taking Figure 1Taking the two groups of swing blades 2 shown in the figure as an example, the unilateral air-sweeping module includes a left air-sweeping signal transmitter, a left air-sweeping signal receiver, a right air-sweeping signal transmitter, and a right air-sweeping signal receiver. The left air-sweeping signal transmitter is the left air-sweeping button set on the remote control (i.e., the left air-sweeping signal transmitting circuit set on the remote control chip), and the left air-sweeping signal receiver is the left air-sweeping signal receiving circuit set on the controller. After the left air-sweeping signal receiving circuit in the controller receives the left air-sweeping signal sent by the remote control, the signal output end of the controller controls the motor corresponding to the left swing blade 2 to start and controls the motor corresponding to the right swing blade 2 to turn off, so that only the left swing blade 2 starts to swing. The right air-sweeping signal transmitter is the right air-sweeping button set on the remote control (i.e., the right air-sweeping signal transmitting circuit set on the remote control chip), and the right air-sweeping signal receiver is the right air-sweeping signal receiving circuit set on the controller. After the right air-sweeping signal receiving circuit in the controller receives the right air-sweeping signal sent by the remote control, the signal output end of the controller controls the motor corresponding to the right swing blade 2 to start and controls the motor corresponding to the left swing blade 2 to turn off, so that only the right swing blade 2 starts to swing.

[0045] The asynchronous air-sweeping module includes an asynchronous air-sweeping signal transmitter and an asynchronous air-sweeping signal receiver. The asynchronous air-sweeping signal transmitter is the asynchronous air-sweeping button set on the remote control (i.e., the asynchronous air-sweeping signal transmitting circuit set on the remote control chip), and the asynchronous air-sweeping signal receiver is the asynchronous air-sweeping signal receiving circuit set on the controller. After the asynchronous air-sweeping signal receiving circuit in the controller receives the asynchronous air-sweeping signal sent by the remote control, the signal output end of the controller controls the motors corresponding to the two groups of swing blades 2 to start, and controls the motors on both sides to drive the swing blades 2 to swing to an included angle state of 180° (see Figure 1 the state shown). Then, it controls the motor on one side to drive the rotating shaft 4 of the swing blade 2 on that side to rotate clockwise, and controls the motor on the other side to drive the rotating shaft 4 of the swing blade 2 on that side to rotate counterclockwise to complete asynchronous air-sweeping. In addition, the above-mentioned asynchronous air-sweeping signal transmitter is an asynchronous air-sweeping button separately set on the remote control. In the actual use process, the asynchronous air-sweeping signal can also be emitted by means of a combination button. For example, the signal frequencies emitted by pressing the left air-sweeping button alone or pressing the right air-sweeping button alone are set as A / B, and after continuously pressing the left air-sweeping button and the right air-sweeping button, a C signal frequency can be emitted, that is, an asynchronous air-sweeping signal is emitted. The above design can be selected according to the actual situation.

[0046] The swing angle of the swing blade 2 includes: as Figure 2 shown, angle a: the included angle between the connection line between the end point of the swing blade 2 facing outside the air outlet 3 and the rotation center of the rotating shaft 4 of the swing blade 2 and the vertical line is not greater than 35 degrees. At this time, the chord line of the swing blade 2 is basically in a vertical state (according to Figure 2 the direction shown in the figure, it means that the included angle between the connection line between the lower end point of the swing blade 2 and the rotation center of the rotating shaft 4 and the vertical line is not greater than 35 degrees). AsFigure 3 As shown, angle b: The swinging blade 2 closes the air outlet 3. As Figure 4 shown, angle c: The included angle between the connection line between the end point of the swinging blade 2 facing the air outlet 3 and the rotation center of the rotation shaft 4 of the swinging blade 2 and the horizontal line is not greater than 5 degrees. At this time, the chord line of the swinging blade 2 is basically in a horizontal state (according to Figure 4 the direction shown in Figure 5 , it means that the included angle between the connection line between the left end point of the swinging blade 2 and the rotation center of the rotation shaft 4 and the horizontal line is not greater than 5 degrees). As Figure 5 shown, angle d: The included angle with angle c is a positive rotation of 15 - 25 degrees (according to Figure 6 the direction shown in Figure 6 , it means that the swinging blade 2 rotates 15 - 25 degrees clockwise from the position where angle c is located to obtain angle d). At this time, it is the angle with the largest air volume output from the air outlet 3. As

[0047] shown, angle e: The included angle with angle c is a positive rotation of 40 - 50 degrees (according to

[0048] the direction shown in

[0049] , it means that the swinging blade 2 rotates 40 - 50 degrees clockwise from the position where angle c is located to obtain angle e). At this time, it is the angle with the largest air output range from the air outlet 3.

[0047] Specifically in use, first turn on the air conditioner by remote control. When initially turning on the air conditioner, the swinging blade 2 swings to the default angle d, or according to the functions of the air conditioner in the prior art, the user can adjust the swinging blade 2 to swing to other angles by themselves.

[0048] When the user needs the swinging blade 2 to perform sweeping ventilation, if synchronous sweeping ventilation is selected, the user selects the synchronous sweeping ventilation button on the remote control. After the controller receives the synchronous sweeping ventilation signal, the motors corresponding to the two groups of swinging blades 2 are both started synchronously and rotate within the range between angle a and angle e in the same direction (specifically, rotate clockwise from angle a to angle e, and then rotate counterclockwise from angle e back to angle a, repeating the cyclic swing) to complete synchronous sweeping ventilation.

[0049] If left - side swinging blade 2 sweeping ventilation is selected, the user selects the left - sweeping ventilation button on the remote control. After the controller receives the left - sweeping ventilation signal, the motor corresponding to the left - side swinging blade 2 is started and drives the left - side swinging blade 2 to rotate within the range between angle a and angle e, while the motor corresponding to the right - side swinging blade 2 is turned off and the right - side swinging blade 2 remains at the current angle without moving. Correspondingly, if right - side swinging blade 2 sweeping ventilation is selected, the user selects the right - sweeping ventilation button on the remote control. After the controller receives the right - sweeping ventilation signal, the motor corresponding to the right - side swinging blade 2 is started and drives the right - side swinging blade 2 to rotate within the range between angle a and angle e, while the motor corresponding to the left - side swinging blade 2 is turned off and the left - side swinging blade 2 remains at the current angle without moving.

[0050] If asynchronous air sweeping is selected, the user selects the asynchronous air sweeping button on the remote control (or the combined button of the left air sweeping button and the right air sweeping button). After the controller receives the asynchronous air sweeping signal, it controls the motor corresponding to the left swing blade 2 to drive the left swing blade 2 to rotate to angle c, and controls the motor corresponding to the right swing blade 2 to drive the right swing blade 2 to rotate to a position 180 degrees from angle c, as shown in Figure 1 the state shown. Then the two motors drive the swing blades 2 on both sides to swing in the opposite direction and swing within the range between angle a and angle e (specifically, the left swing blade 2 first rotates clockwise from angle c to angle e, and then rotates counterclockwise from angle e back to angle a, repeating this cycle; while the right swing blade 2 first rotates counterclockwise from its initial angle back to angle a, and then rotates clockwise from angle a to angle e, repeating this cycle).

[0051] Preferably, on the basis of Embodiment 1, the control component further includes an anti-direct-blowing module. The anti-direct-blowing module is used to control the swing blade 2 to swing to direct the wind from the air outlet 3 horizontally, upward or downward. Specifically, the anti-direct-blowing module includes an anti-direct-blowing signal transmitter and an anti-direct-blowing signal receiver. The anti-direct-blowing signal transmitter is the anti-direct-blowing button set on the remote control (i.e., the anti-direct-blowing signal transmitting circuit set on the remote control chip), and the anti-direct-blowing signal receiver is the anti-direct-blowing signal receiving circuit set on the controller. After the anti-direct-blowing signal receiving circuit in the controller receives the anti-direct-blowing signal sent by the remote control, the signal output end of the controller controls the motors corresponding to the two groups of swing blades 2 to drive the swing blades 2 to rotate to angle a or angle c, as shown in Figure 2 and Figure 4 shown. Angle a is the direction to direct the wind from the air outlet 3 downward, and angle c is the direction to direct the wind from the air outlet 3 horizontally and slightly upward.

[0052] During actual use, when the air conditioner is in the cooling mode, after the controller obtains the anti-direct-blowing signal, the signal output end of the controller controls the motors corresponding to the two groups of swing blades 2 to drive the swing blades 2 to rotate to angle c and stay still; when the air conditioner is in the heating mode, after the controller obtains the anti-direct-blowing signal, the signal output end of the controller controls the motors corresponding to the two groups of swing blades 2 to drive the swing blades 2 to rotate to angle a and stay still.

[0053] Preferably, on the basis of Embodiment 1, the control component further includes a power-off memory module. The power-off memory module refers to the reference design of air conditioners with power-off memory function in the prior art. In the case of air conditioner failure, sudden power outage, shutdown, etc., the power-off memory module memorizes the previous operating state of the swing blade 2. Then, after the air conditioner is restarted, it can operate according to the previously memorized operating state of the swing blade 2 to meet the user's usage habits.

[0054] Embodiment 2

[0055] Taking the air conditioner starting the cooling mode as an example, the zoned air control method is as follows:

[0056] When the air conditioner is in the on state, obtain the operating mode of the air conditioner, and determine whether the air conditioner is starting the cooling mode for the first time. If it is starting the cooling mode for the first time, the controller controls the swing blade 2 to rotate to the default angle d. If it is not starting the cooling mode for the first time, the controller controls the swing blade 2 to operate in the memory state.

[0057] When the user has a need for air sweeping, after the controller obtains the synchronous air sweeping or asynchronous air sweeping or left air sweeping or right air sweeping signal, according to the corresponding air sweeping signal, the controller controls the swing blade 2 to swing. Specifically, after the controller obtains the synchronous air sweeping signal, it controls the two side swing blades 2 to swing back and forth within the range between angle c and angle e at the same speed and in the same direction (specifically, rotating clockwise from angle c to angle e, and then rotating counterclockwise from angle e back to angle c, repeating the cyclic swing). After the controller obtains the asynchronous air sweeping signal, it controls the two side swing blades 2 to swing back and forth in the opposite direction within the range between angle c and angle e (specifically, the left swing blade 2 first rotates clockwise from angle c to angle e, and then rotates counterclockwise back to angle c, repeating the cyclic swing; while the right swing blade 2 first rotates counterclockwise back to angle c from its initial angle, and then rotates clockwise from angle c to angle e, repeating the cyclic swing). After obtaining the left air sweeping signal, it controls the left swing blade 2 to swing back and forth within the range between angle c and angle e, while the right swing blade 2 remains stationary at the current angle; after obtaining the right air sweeping signal, it controls the right swing blade 2 to swing back and forth within the range between angle c and angle e, while the left swing blade 2 remains stationary at the current angle.

[0058] After the user no longer needs air sweeping, after the controller obtains the stop air sweeping signal (the control component includes a stop air sweeping module, specifically including a stop air sweeping signal transmitting circuit provided on the remote control chip and a stop air sweeping signal receiving circuit provided in the controller), it controls the two side swing blades 2 to remain stationary at the current angle.

[0059] When the user needs to prevent direct blowing, the controller obtains the anti-direct-blowing signal and controls the two side swing blades 2 to rotate to angle c and remain stationary until the anti-direct-blowing signal is obtained again, and then controls the two side swing blades 2 to resume the operating state before anti-direct-blowing.

[0060] When the controller obtains signals such as the air conditioner entering a fault, protection shutdown, or shutdown, it memorizes the current swing angle range, direction, speed, and other operating states of the swing blade 2. When the controller obtains signals such as the air conditioner exiting the fault and restarting, it restores the operating state of the swing blade 2 memorized by the air conditioner.

[0061] Through the control of the above synchronous air sweeping, the air conditioner can achieve synchronous air sweeping throughout the house in the cooling mode, which is suitable for the use environment where the whole house needs to be quickly cooled; through the control of unilateral air sweeping, it can achieve separate air supply control for different areas when the indoor environmental temperature is uneven, the indoor personnel distribution is uneven, or the refrigeration requirements of indoor users are different; through the control of asynchronous air sweeping, the two side swing blades 2 sweep the air simultaneously in opposite directions, which can quickly stir the indoor air and is conducive to uniform and rapid cooling of the whole house.

[0062] Embodiment 3

[0063] Taking the air conditioner starting the heating mode as an example, the zoning air control method is as follows:

[0064] When the air conditioner is in the on state, the controller obtains that the air conditioner is in the heating mode and controls the swing blade 2 to rotate to the default angle d.

[0065] When the user has a demand for air sweeping, after the controller obtains the synchronous air sweeping or asynchronous air sweeping or left air sweeping or right air sweeping signal, according to the corresponding air sweeping signal, the controller controls the swing blade 2 to swing. Specifically, after the controller obtains the synchronous air sweeping signal, it controls the two side swing blades 2 to swing back and forth within the range between angle c and angle e at the same speed and in the same direction. In the heating mode, the synchronous air sweeping angle should be as large as possible. In the actual use process, it can be set to swing back and forth within the range between angle a and angle e. However, since large-angle air sweeping will also cause a certain amount of noise, therefore, by default, the swing blade 2 swings back and forth within the range between angle c and angle e during synchronous air sweeping, that is, the same as the air sweeping angle range in the cooling mode. And since in the cooling mode, the cold air is easy to sink, large-angle air stirring is not conducive to the cold air flow effect. Therefore, in the cooling mode, whether it is synchronous air sweeping, asynchronous air sweeping or unilateral air sweeping, the swing blade 2 swings back and forth within the range between angle c and angle e.

[0066] After the controller obtains the asynchronous air sweeping signal, it controls the two side swing blades 2 to swing back and forth in opposite directions within the range between angle a and angle e; after obtaining the left air sweeping signal, it controls the left swing blade 2 to swing back and forth within the range between angle a and angle e, while the right swing blade 2 remains stationary at the current angle; after obtaining the right air sweeping signal, it controls the right swing blade 2 to swing back and forth within the range between angle a and angle e, while the left swing blade 2 remains stationary at the current angle. During asynchronous air sweeping and unilateral air sweeping, the swing blade 2 swings at a large angle, expanding the stirring effect on the air and achieving more rapid uniform heating of the whole house.

[0067] After the user does not need air sweeping, after the controller obtains the stop air sweeping signal (the control component includes a stop air sweeping module, specifically including a stop air sweeping signal transmitting circuit arranged on the remote control chip and a stop air sweeping signal receiving circuit arranged in the controller), it controls the two side swing blades 2 to remain stationary at the current angle.

[0068] When the user needs to prevent direct blowing, the controller obtains the anti-direct-blowing signal and controls both side swing blades 2 to rotate to angle a and remain stationary until the anti-direct-blowing signal is obtained again, at which point the controller controls the two side swing blades 2 to resume the operating state before anti-direct blowing.

[0069] After the controller obtains signals such as the air conditioner entering a fault, protecting and shutting down, or entering the defrosting state, it memorizes the operating states of the swing blade 2, such as the current swinging angle range, direction, and speed. After the controller obtains signals such as the air conditioner exiting a fault or ending the defrosting state, it restores the operating state of the swing blade 2 memorized by the air conditioner.

[0070] In the heating mode, it is not necessary to memorize the current operating state of the swing blade 2 when shutting down. Because in the heating mode, in order to achieve better heating effect after starting up, it is necessary to make as much hot air blow out as possible, so it is default that the swing blade 2 is directly swung to angle d when starting up, and there is no need to memorize the operating state of the swing blade 2 when shutting down.

[0071] Preferably, on the basis of Embodiment 3, when the air conditioner is in the heating mode, the controller obtains the rotation speed of the indoor fan of the air conditioner. When the fan speed is not less than the factory-set value of the air conditioner itself, it controls the swing blade 2 to swing within the range between angle c and angle e; when the fan speed is less than the factory-set value of the air conditioner itself, the swing blade 2 swings within the range between angle a and angle e.
