Description

Technical Field

[0001] This invention relates to air conditioners, and more particularly to a method, apparatus and air conditioner for controlling the oscillation of air guide vanes. Background Technology

[0002] like Figure 1 As shown, the air conditioner includes a first air guide vane 101 and a second air guide vane 102. Overlapping portions 103 are provided on the first air guide vane 101 and the second air guide vane 102. In the closed state, the overlapping portions 103 of the first air guide vane 101 and the second air guide vane 102 overlap, making the first air guide vane 101 and the second air guide vane 102 close more tightly, thereby enabling the air conditioner to better prevent dust or oil stains.

[0003] When a conventional air conditioner receives a command to activate the swing function, it typically controls the air deflectors to swing simultaneously to deliver air. However, when the control is as follows... Figure 1 When the first guide vane 101 and the second guide vane 102 shown swing clockwise, the overlapping part of the first guide vane 101 and the second guide vane 102 interferes with the swing process, making it difficult for them to swing normally.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0030] It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other examples obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

[0032] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] Furthermore, in the description of this application, unless otherwise stated, "several" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0034] The technical solutions disclosed in this application can be applied to air conditioners with overlapping fan blade structures, such as kitchen air conditioners installed in the ceiling. By setting overlapping fan blade structures, kitchen air conditioners can achieve seamless blades and improve the sealing performance of the blades, thereby effectively preventing kitchen oil stains from entering the interior of the kitchen air conditioner, improving the service life of the kitchen air conditioner and the user experience.

[0035] Please see Figure 2 This is a schematic diagram of the structure of an air conditioner according to one embodiment of this application. The air conditioner includes a first air guide vane 201, a second air guide vane 202, a first limiting device 204, and a second limiting device 205. The first limiting device 204 is used to limit the upper limit position of the swing of the first air guide vane 201, and the second limiting device 205 is used to limit the upper limit position of the swing of the second air guide vane 202.

[0036] Overlapping portions 203 are provided on the first air guide blade 201 and the second air guide blade 202. When the air conditioner is turned off, the first air guide blade 201 and the second air guide blade 202 are closed, and the overlapping portion 203 of the first air guide blade 201 is superimposed on the overlapping portion 103 of the second air guide blade 202, so that the first air guide blade 201 and the second air guide blade 202 can be closed more tightly, thereby better preventing dust or oil stains.

[0037] like Figure 2 As shown, when the first guide vane 201 and the second guide vane 202 swing simultaneously, the second guide vane 202 is restricted by the first guide vane 201 and the second limiting device 205, and cannot open normally, affecting the normal air supply of the air conditioner.

[0038] Therefore, for the above issues, please refer to [link / reference]. Figure 3 This invention provides a method for controlling the oscillation of air guide vanes, the method comprising the following steps:

[0039] S101: In response to the air conditioner's turn-on command, control the first air guide vane to swing along the first swing direction to the first set position;

[0040] S102: Control the second guide vane to swing along the second swing direction to a second set position; wherein the first swing direction is opposite to the second swing direction;

[0041] S103: Control the first guide vane and the second guide vane to swing to the target position;

[0042] S104: In response to the swing opening command of the air guide blade, control the first air guide blade and the second air guide blade to swing within a preset swing range.

[0043] In step S101, the air conditioner's start command can be a command issued by the user's control device (e.g., a remote control) to turn on the air conditioner. After receiving the command, the air conditioner controls the compressor to start running and adjusts the indoor ambient temperature.

[0044] It should be noted that in this embodiment of the application, after the air conditioner is turned on, the first and second air guide vanes do not swing to deliver air. Only after receiving the user's command to start swinging the air guide vanes do the first and second air guide vanes begin to swing and deliver air in different directions.

[0045] The first swing direction can be determined based on the type of air conditioner and the swing directions of the first and second air guide vanes. For example, for air conditioners like... Figure 2 The air conditioner shown can swing in a counter-clockwise direction.

[0046] The first preset position is a position pre-selected by the user within the range of the first guide vane's swing range. Specifically, when the first guide vane swings to the first preset position, the second guide vane can swing in any direction without contacting the first guide vane, thus ensuring that the swinging process of the second guide vane is not interfered with by the first guide vane. The first preset position can be determined based on the blade lengths and distance between the first and second guide vanes; for example, it can be set at a 90° angle perpendicular to the closed position of the first guide vane.

[0047] In step S102, the second swing direction is opposite to the first swing direction. For example, if the first swing direction can be counterclockwise, then the second swing direction can be clockwise.

[0048] The second set position can be a position that the user has selected in advance within the range of the swing position of the second guide vane. In one embodiment, when the second guide vane swings to the second set position, the first guide vane can be parallel to the second guide vane, so that the first guide vane and the second guide vane can be simultaneously controlled to swing to the target position in step S103.

[0049] In step S103, the target location can be determined based on the initial location information preset by the user, or based on the location information of the first and second air guide vanes when the air conditioner was last turned off.

[0050] If the first guide vane and the second guide vane are currently in a parallel position, controlling the first guide vane and the second guide vane to swing to the target position can be done by controlling the first guide vane and the second guide vane to swing to the target position along the same target swing direction.

[0051] The target swing direction can be determined based on the positional relationship between the target position and the first and second set positions. For example, if the target position is to the left of the first set position, the first and second guide vanes can be controlled to swing clockwise to the target position.

[0052] In step S104, the swing start command for the air guide vanes can be a command issued by the user's control device (e.g., remote control) to control the air guide vanes to start swinging. After receiving the command, the air conditioner controls the first and second air guide vanes to swing back and forth within a preset swing range.

[0053] The swing range is used to determine the upper and lower limits of the swing range for the first and second guide vanes.

[0054] The first air guide blade can be the lower blade of the air conditioner, and the second air guide blade can be the upper blade of the air conditioner. Controlling the swing of the first air guide blade and the second air guide blade can be controlling the first air guide blade and the second air guide blade to swing up and down within the swing range.

[0055] It should be noted that controlling the first guide vane and / or the second guide vane to swing to a certain position in the above steps can be achieved by controlling the corresponding drive motor of the first guide vane and / or the second guide vane to rotate the corresponding number of steps. The number of steps of the drive motor rotation can be determined according to the correspondence between the swing position and the number of steps.

[0056] like Figure 4 As shown, the following is a schematic diagram of the operation of the first air guide vane 301 and the second air guide vane 302 during the air conditioner's operation in one embodiment.

[0057] Upon receiving the air conditioner's start command, the first air guide vane 301 is controlled to swing counterclockwise to a 90° position. After the first air guide vane 301 reaches this position, the second air guide vane 302 can swing independently of the first air guide vane 301. The second air guide vane 302 is controlled to swing clockwise to a 90° position. After the second air guide vane 302 reaches this position, the first air guide vane 301 and the second air guide vane 302 are parallel. The first air guide vane 301 and the second air guide vane 302 are controlled to swing clockwise simultaneously to the target position. After the first air guide vane 301 and the second air guide vane 302 reach the target position, the first air guide vane 301 and the second air guide vane 302 are controlled to swing according to the user's air guide vane swing start command, sending air in different directions.

[0058] In this embodiment, when the air conditioner is turned on, the first air guide vane is controlled to swing along the first swing direction to the first set position to avoid the first air guide vane interfering with the normal operation of the second air guide vane, and the second air guide vane is controlled to swing along the second swing direction to the second set position. Furthermore, by controlling the first air guide vane and the second air guide vane to swing along the target swing direction to the same target position, the first air guide vane and the second air guide vane can be controlled to swing within a preset swing range according to the user's swing start command. This application can enable closed overlapping air guide vanes to open normally without interference, avoiding mutual interference between overlapping air guide vanes.

[0059] In one embodiment, the step of controlling the first guide vane and the second guide vane to swing within a preset swing range specifically includes:

[0060] Control the first guide vane and the second guide vane to swing simultaneously within a preset swing range;

[0061] If the first guide vane has swung to the first threshold position and the second guide vane has not swung to the second threshold position, the first guide vane is controlled to stop swaying until the second guide vane swung to the second threshold position.

[0062] or,

[0063] If the second guide vane has swung to the second threshold position and the first guide vane has not swung to the first threshold position, control the second guide vane to stop swaying until the first guide vane swung to the first threshold position.

[0064] The first threshold position can refer to the upper or lower limit position of the first guide vane's swing, and the second threshold position can refer to the upper or lower limit position of the second guide vane's swing.

[0065] Controlling the first guide vane and the second guide vane to swing simultaneously within a preset swing range can be controlled by controlling the first guide vane and the second guide vane to swing within their corresponding swing ranges. The swing range can include an upper limit position for upward swing and a lower limit position for downward swing. The swing range of the first guide vane can be the same as that of the second guide vane, or the swing range of the first guide vane can be different from that of the second guide vane.

[0066] When the swing range of the first guide vane is different from that of the second guide vane, the guide vane that swings to the threshold position first stops swinging and waits for the other guide vane to reach the threshold position before the two guide vanes swing synchronously.

[0067] The first and second guide vanes can swing up and down between the upper limit position and the lower limit position. When the guide vane swings upward, the highest position of the swing does not exceed the corresponding upper limit position. When the guide vane swings downward, the lowest position of the swing does not exceed its corresponding lower limit position.

[0068] In this embodiment, the first and second air guide vanes are controlled to swing synchronously in the same direction. To avoid asynchrony caused by the different swing ranges of the first and second air guide vanes, this embodiment stops swinging when either the first or second air guide vane reaches the upper or lower limit position first, and waits for the other air guide vane to reach the same upper or lower limit position before swinging together. This ensures that the first and second air guide vanes can swing synchronously, avoids mutual interference between the first and second air guide vanes affecting the normal operation of the air conditioner, and improves the user experience.

[0069] During the operation of the air conditioner, the user can turn off the air conditioner according to the actual operating needs. After turning off the air conditioner, the user can control the first air guide blade and the second air guide blade to swing to their corresponding closed positions, so that the overlapping part of the first air guide blade is superimposed on the overlapping part of the second air guide blade, so as to achieve seamless closure of the first air guide blade and the second air guide blade, thereby ensuring the airtightness of the air conditioner.

[0070] When controlling the first and second air guide vanes to swing to their corresponding closed positions, the first and second air guide vanes can be directly controlled to swing to their corresponding closed positions along a certain swing direction. However, in the above process, the first and second air guide vanes may still interfere with each other's swing. Or, during the operation of the air conditioner, the air guide vanes may be obstructed or manually bent, causing their swing positions to become abnormal. Since the air conditioner lacks a detection device, it cannot detect the abnormal position of the air guide vanes, thus affecting the normal operation of the air conditioner.

[0071] Therefore, in order to ensure that the air guide vanes can close normally, after receiving the air conditioner's shutdown command, the first and second air guide vanes can be instructed to perform a closing reset action, so that the first and second air guide vanes can close normally, thereby ensuring that the air guide vanes can operate normally when they are turned on again.

[0072] Therefore, please refer to Figure 5 In a preferred embodiment, the guide vane oscillation control method further includes the following steps:

[0073] S105: In response to the air conditioner's shutdown command, control the first air guide vane to swing along the first swing direction to the second set position;

[0074] S106: Control the second guide vane to swing along the first swing direction to the second closed position;

[0075] S107: Control the first guide vane to swing along the second swing direction to the first closed position.

[0076] The second set position can be determined based on the blade length and distance of the first and second guide vanes. For example, the second set position can be set to a 90° position perpendicular to the closed position of the first guide vane.

[0077] The first closed position refers to the position when the first guide vane is in a closed state, and the second closed position refers to the position when the second guide vane is in a closed state. For example, in the embodiments of this application, the first closed position and the second closed position can be horizontal positions parallel to the ground.

[0078] Specifically, the step of controlling the second guide vane to swing along the first swing direction to the second closed position includes:

[0079] Control the drive motor corresponding to the second guide vane to rotate one step, so that the second guide vane swings along the first swing direction to the second closed position;

[0080] The drive motor is used to drive the second guide vane to swing. One end of the second guide vane can be fixedly mounted on the shaft of the drive motor. When the drive motor rotates, the second guide vane swings under the drive of the drive motor.

[0081] Preferably, when controlling the second guide vane to swing to the second closed position along the first swing direction, the number of the first step can be greater than the maximum number of swing steps of the second guide vane, wherein the maximum number of swing steps is the maximum number of swing steps within the swing range of the second guide vane.

[0082] By making the first step number greater than the maximum number of swing steps of the second guide vane, it is ensured that the second guide vane can swing completely to the closed position, thus ensuring the normal closure of the second guide vane.

[0083] The steps of controlling the first guide vane to swing along the second swing direction to the first closed position specifically include:

[0084] The drive motor corresponding to the first guide vane is controlled to rotate a second number of steps, so that the first guide vane swings along the second swing direction to the first closed position; wherein the second number of steps is greater than the maximum number of swing steps that the first guide vane can swing.

[0085] The drive motor is used to drive the first guide vane to swing. One end of the first guide vane can be fixedly mounted on the shaft of the drive motor. When the drive motor rotates, the first guide vane swings under the drive of the drive motor.

[0086] Preferably, when controlling the first guide vane to swing along the second swing direction to the first closed position, the second step number is made greater than the maximum swing step number of the first guide vane, wherein the maximum swing step number is the maximum number of swing steps within the swing range of the first guide vane.

[0087] By making the second step number greater than the maximum swing number of the first guide vane, it is ensured that the first guide vane can swing completely to the closed position, thus ensuring the normal closure of the first guide vane.

[0088] Please see Figure 6 This is a schematic diagram illustrating the closing and resetting action of the first guide vane 301 and the second guide vane 302 in one embodiment. Figure 6 As shown, during the operation of the air conditioner, the second air guide vane 302 was manually bent to the position shown. Figure 6At the angle shown, the air conditioner cannot know that the second air guide vane 302 has not yet been reset. Furthermore, since the first air guide vane 301 is already in the closed position, the second air guide vane is obstructed by the first air guide vane 301 and cannot swing to the closed position to close.

[0089] In this embodiment, the first guide vane 301 is first swung counterclockwise to a 90° position so that it does not affect the swaying of the second guide vane 302. Then, the second guide vane 302 is controlled to sway counterclockwise, and the number of swaying steps of the second guide vane 302 is greater than the maximum number of swaying steps within its swaying range, so that the second guide vane 302 can fully reach the closed position. After the second guide vane 302 reaches the closed position, the first guide vane 301 is controlled to sway clockwise, and the number of swaying steps of the first guide vane 301 is greater than the maximum number of swaying steps within its swaying range, so that the first guide vane 301 can fully reach the closed position, thereby achieving the closed reset of the first guide vane 301 and the second guide vane 302.

[0090] In this embodiment of the application, when the air conditioner is turned off, the first air guide blade is first controlled to swing along the first swing direction to the second set position to avoid interfering with the closing of the second air guide blade. After the second air guide blade swings along the first swing direction to the second closed position, the first air guide blade is then controlled to swing along the second swing direction to the first closed position, thereby ensuring that both the first and second air guide blades can close normally, ensuring that the air guide blades can operate normally when turned on next time, and improving the user experience.

[0091] During the operation of the air conditioner, the user can control the air guide blades to stop swinging as needed. If the user receives a command to turn off the swing of the air guide blades during the swinging process of the first and second air guide blades, the first and second air guide blades will stop swinging and remain at their current positions. If the user receives a command to turn on the swing of the air guide blades again, the first and second air guide blades will start swinging again from their current positions.

[0092] If the system receives a user's command to turn off the air conditioner after the air guide vanes have stopped oscillating, it can memorize the current positions of the first and second air guide vanes and use these positions as the target positions. This allows the air conditioner to automatically control the first and second air guide vanes to move to the positions they were in when it was last turned off, and automatically deliver air according to the airflow direction adjusted by the user last time, thereby improving the user experience.

[0093] Specifically, such as Figure 7 As shown, the method further includes the following steps:

[0094] S201: In response to the wind deflection shut-off command of the wind deflector blades, control the first wind deflector blades and the second wind deflector blades to stop swinging;

[0095] S202: In response to the air conditioner's shutdown command, record the swing position information of the first air guide vane and the second air guide vane, and update the target position based on the swing position information of the first air guide vane and the second air guide vane.

[0096] The swing position information of the first and second guide vanes is used to determine the swing position of the first and second guide vanes when they stop swinging.

[0097] Updating the target position can replace the original target position with the swing position of the first and second air guide vanes when the swing stops, so that when the air conditioner is started again, steps S101-S103 can be executed automatically, so that the first and second air guide vanes can deliver air according to the wind direction position set by the user last time.

[0098] In this embodiment of the application, after controlling the first and second air guide vanes to stop swinging, if a shutdown command for the air conditioner is received, the current positions of the first and second air guide vanes are memorized and used as the target positions for the next startup, so that the air conditioner can automatically deliver air according to the air direction position adjusted by the user last time, thereby improving the user experience.

[0099] If the air conditioner encounters a power outage or is shut down without controlling the air guide vanes to stop swinging during operation, the air conditioner has not had time to memorize the previous swing position information. In this case, the target position can be determined based on the preset initial position information. Specifically, after controlling the first air guide vane to swing along the second swing direction to the first closed position, the method further includes the following steps:

[0100] The target position is updated according to the preset initial position information.

[0101] Alternatively, if the power supply to the air conditioner is detected to be disconnected, the target position is updated according to the preset initial position information.

[0102] The initial position information is used to determine the initial position of the air conditioner's air guide vanes. After updating the target position according to the preset initial position information, the first and second air guide vanes move to the initial position for standby after the unit is turned on. After receiving the user's air guide vane swing start command, they start swinging and blowing air from the initial position.

[0103] If the power supply is disconnected during the operation of the air conditioner, the air conditioner will stop all operations due to power failure. The air guide blades will maintain the swing position when the power was lost. If the air conditioner is powered on and turned on, when the start-up action of steps S101-S104 is performed, the first and second air guide blades that are not properly closed are prone to mutual interference, which will prevent the air conditioner from starting normally.

[0104] Therefore, to address the aforementioned problems, this application embodiment, before controlling the first air guide vane to swing along the first swing direction to the first preset position in response to the air conditioner's turn-on command, further includes the following steps:

[0105] If the power supply to the air conditioner is detected to be turned on, the first air guide blade is controlled to swing along the first swing direction to the second set position.

[0106] Control the second guide vane to swing along the first swing direction to the second closed position;

[0107] Control the first guide vane to swing along the second swing direction to the first closed position.

[0108] When the air conditioner is detected to be powered on, the first and second air guide vanes are automatically controlled to perform a reset action, so that the first air guide vane is in the first closed position and the second air guide vane is in the second closed position. This allows the first and second air guide vanes to open normally in response to the air conditioner's start command, avoiding affecting the normal operation of the air conditioner.

[0109] like Figure 8 As shown, this application also provides a guide vane oscillation control device. The air conditioner includes a first guide vane and a second guide vane, with overlapping portions on the first and second guide vanes. The first guide vane is in a first closed position, and the second guide vane is in a second closed position. The overlapping portion of the first guide vane is superimposed on the overlapping portion of the second guide vane. The device includes:

[0110] The first swing module 401 is used to control the first air guide blade to swing along the first swing direction to a first set position in response to the air conditioner's turn-on command.

[0111] The second swing module 402 is used to control the second air guide vane to swing along the second swing direction to a second set position; wherein the first swing direction is opposite to the second swing direction.

[0112] The third swing module 403 is used to control the first guide vane and the second guide vane to swing to the target position;
