Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an air conditioner and its anti-pinch control method, device and storage medium. Background Technology

[0002] In related technologies, when an air conditioner performs left and right air sweeping, the air guide vanes and the outer air guide plates will rotate back and forth. However, due to the different rotation speeds and strokes of the air guide vanes and air guide plates, they are prone to misalignment during rotation, which poses a risk of pinching fingers when the air conditioner is running. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, the first objective of the present invention is to provide an anti-pinch control method for air conditioners to eliminate the risk of pinching fingers.

[0004] A second objective of this invention is to provide a computer-readable storage medium.

[0005] The third objective of this invention is to provide an air conditioner.

[0006] The fourth objective of this invention is to provide an anti-pinch control device for an air conditioner.

[0007] To achieve the above objectives, a first aspect of the present invention provides an anti-pinch control method for an air conditioner. The air conditioner housing defines an air outlet, and a first air guide is provided at the air outlet. The first air guide rotates around a vertical axis to change the air outlet direction. The air conditioner also includes a second air guide, which is movably disposed outside the air outlet. The second air guide includes multiple air guide plates, which are spaced apart to define a first air outlet channel. A second air outlet channel is defined between the second air guide and both sides of the air outlet, so that the air conditioner has a three-way air outlet state. The method includes: when the first air guide and the second air guide rotate in the same direction to enable the air conditioner to perform three-way air outlet, transmitting a detection signal through the first air guide to the first air outlet channel; when the detection signal is blocked by the first air guide, controlling the first air guide to stop rotating and controlling the second air guide to continue rotating.

[0008] According to the anti-pinch control method of the air conditioner according to the embodiment of the present invention, when the air conditioner is discharging air in three directions, it can determine whether the air conditioner has a risk of pinching fingers based on whether the detection signal is blocked by the first air guide component. When there is a risk of pinching fingers, the action of the first air guide component and the second air guide component is controlled to eliminate the risk of pinching fingers, thereby realizing the anti-pinch function of the air conditioner and improving the safety of the air conditioner.

[0009] According to some embodiments of the present invention, when the detection signal is not blocked by the first air guide, the method further includes: determining the rotation time of the first air guide, and when the rotation time of the first air guide reaches a first preset time, controlling the first air guide to stop rotating, and controlling the second air guide to continue rotating.

[0010] According to some embodiments of the present invention, after controlling the first air guide to stop rotating, the method further includes: determining the rotation time of the second air guide, and when the rotation time of the second air guide reaches a second preset time, controlling the first air guide and the second air guide to rotate in opposite directions simultaneously.

[0011] According to some embodiments of the present invention, the detection signal is emitted by a signal generator disposed inside the air outlet, wherein the signal generator rotates in the same direction as the first air guide and the second air guide to emit the detection signal toward the first air outlet channel.

[0012] Furthermore, the first air guide includes a plurality of air guide strips, and a signal receiver is provided on the air guide strip whose position is adapted to the signal generator. When the signal receiver receives the detection signal, it is determined that the detection signal is blocked by the first air guide.

[0013] Furthermore, the detection signal passes between two adjacent middle air guides among the plurality of air guides, and the distance S between the projection point of the signal generator on the vertical plane formed by the two adjacent middle air guides and the middle air guide satisfies the relationship: H / 3 < S < H / 2, where H is the interval between the two adjacent middle air guides.

[0014] Furthermore, the rotational angular velocity of the first air guide is greater than the rotational angular velocity of the signal generator, and the rotational angular velocity of the signal generator is greater than the rotational angular velocity of the second air guide.

[0015] To achieve the above objectives, a second aspect of the present invention provides a computer-readable storage medium storing an anti-pinch control program for an air conditioner, wherein the anti-pinch control program for the air conditioner, when executed by a processor, implements the anti-pinch control method for the air conditioner as described above.

[0016] According to the computer-readable storage medium of the present invention, the above-described anti-pinch control method can determine whether the air conditioner poses a risk of pinching fingers when the air conditioner has three air outlets, based on whether the detection signal is blocked by the first air guide. If there is a risk of pinching fingers, the action of the first air guide and the second air guide can be controlled to eliminate the risk of pinching fingers, thereby realizing the anti-pinch function of the air conditioner and improving the safety of the air conditioner.

[0017] To achieve the above objectives, a third aspect of the present invention provides an air conditioner, including a memory, a processor, and an anti-pinch control program for the air conditioner stored in the memory and executable on the processor. When the processor executes the anti-pinch control program for the air conditioner, it implements the anti-pinch control method for the air conditioner as described above.

[0018] According to the present invention, when the air conditioner has three air outlets, the method described above can determine whether the air conditioner poses a risk of pinching fingers by detecting whether the detection signal is blocked by the first air guide. If there is a risk of pinching fingers, the operation of the first and second air guides can be controlled to eliminate the risk of pinching fingers, thereby realizing the anti-pinch function of the air conditioner and improving the safety of the air conditioner.

[0019] To achieve the above objectives, a fourth aspect of the present invention provides an anti-pinch control device for an air conditioner. The air conditioner housing defines an air outlet, and a first air guide is provided at the air outlet. The first air guide rotates about a vertical axis to change the air outlet direction. The air conditioner also includes a second air guide, which is movably disposed outside the air outlet. The second air guide includes multiple air guide plates, which are spaced apart to define a first air outlet channel. A second air outlet channel is defined between the second air guide and both sides of the air outlet, so that the air conditioner has a three-way air outlet state. The device includes: a signal transmitting module, used to transmit a detection signal through the first air guide to the first air outlet channel when the first air guide and the second air guide rotate in the same direction to enable the air conditioner to perform three-way air outlet; and a control module, used to control the first air guide to stop rotating and control the second air guide to continue rotating when the detection signal is blocked by the first air guide.

[0020] According to the anti-pinch control device of the present invention, when the air conditioner has three air outlets, the control module can determine whether the air conditioner has a risk of pinching fingers based on whether the detection signal is blocked by the first air guide. When there is a risk of pinching fingers, the control module can eliminate the risk of pinching fingers by controlling the action of the first air guide and the second air guide, thereby realizing the anti-pinch function of the air conditioner and improving the safety of the air conditioner.

[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0042] In the description of this invention, it is understood that the terms “height,” “up,” “down,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience and simplification of describing this invention, and are not intended to indicate or imply that the elements or devices referred to must have a specific orientation, and therefore should not be construed as limiting this invention.

[0043] The following is combined with Figures 1-8 A detailed description of the anti-pinch control method for an air conditioner according to an embodiment of the present invention is provided.

[0044] Reference Figures 3-7 As shown, the air conditioner housing 1 defines an air outlet 11, which is connected to the air duct component 6 inside the housing 1. The air duct component 6 can discharge air through the air outlet 11 to regulate environmental parameters such as temperature and humidity. A first air guide 2 is provided at the position of the air outlet 11. The first air guide 2 can rotate around a vertical axis, thereby changing the air discharge direction of the air outlet 11. The first air guide 2 may include one or more air guide strips 21. The air guide strips 21 can be vertical air guide strips. The air guide strips 21 can extend along the height direction of the air conditioner. Each air guide strip 21 can rotate around its own vertical axis, thereby changing the air discharge direction of the air outlet 11 in the left and right directions. The vertical axis can be the central axis of the air guide strip 21, and the rotation of the air guide strip 21 can be a rotation around its central axis.

[0045] The air conditioner also includes a second air guide 3, which is movably disposed outside the air outlet 11. That is, in the air outlet path of the air conditioner, the second air guide 3 is located downstream of the first air guide 2. By moving the second air guide 3, the air outlet parameters after the air is discharged from the air outlet 11 can be further adjusted. That is, the second air guide 3 can adjust the final air outlet direction, air volume and other air outlet parameters of the air conditioner. The movement trajectory of the second air guide 3 can be an arc-shaped trajectory with the air guide axis a as the center. The air guide axis a is located outside the second air guide 3. That is, the movement of the second air guide 3 can be regarded as the second air guide 3 revolving around the air guide axis a within a certain angle range.

[0046] The second air guide 3 includes multiple air guide plates, which can be two, three, four, etc. The air outlet state of the air conditioner can be controlled by adjusting the movement state of the multiple air guide plates. The multiple air guide plates are spaced apart to define the first air outlet channel 13, and the second air guide 3 defines the second air outlet channel 14 between the two sides of the air outlet 11, so that the air conditioner has a three-way air outlet state. It can be understood that in the three-way air outlet state, the multiple air guide plates are divided into two groups of spaced left and right to form the first air outlet channel 13 between the two groups, and a second air outlet channel 14 is formed on the left and right sides of the two groups respectively. The air conditioner vents air through the three openings towards the air outlet channels in different directions, thereby realizing the three-way air outlet state of the air conditioner.

[0047] In some embodiments of the present invention, reference is made to... Figures 3-7 As shown, the second air guide 3 includes a left air guide plate 31 and a right air guide plate 32. In the three-way air outlet state, the left air guide plate 31 and the right air guide plate 32 can move back and forth synchronously around the air guide axis a outside the air outlet 11 to achieve left and right air sweeping of the air conditioner. The distance between the left air guide plate 31 and the right air guide plate 32 remains unchanged. That is, when the left air guide plate 31 and the right air guide plate 32 move to the left synchronously around the air guide axis a outside the air outlet 11, the opening size of the first air outlet channel 13 formed between the left air guide plate 31 and the right air guide plate 32 remains unchanged. The opening of the second air outlet channel 14 formed between the left and right sides of the air outlet 11 becomes smaller, and the opening of the second air outlet channel 14 formed between the right guide plate 32 and the right side of the air outlet 11 becomes larger. When the left guide plate 31 and the right guide plate 32 move to the right around the guide axis a outside the air outlet 11, the opening size of the first air outlet channel 13 formed between the left guide plate 31 and the right guide plate 32 remains unchanged, the opening of the second air outlet channel 14 formed between the left guide plate 31 and the left side of the air outlet 11 becomes larger, and the opening of the second air outlet channel 14 formed between the right guide plate 32 and the right side of the air outlet 11 becomes smaller.

[0048] Figure 1 The flowchart of the anti-pinch control method according to an embodiment of the present invention is shown below. Figure 1 As shown, the method includes:

[0049] Step S1: When the first air guide and the second air guide rotate in the same direction to make the air conditioner perform three-way air outlet, a detection signal is transmitted through the first air guide to the first air outlet channel.

[0050] The detection signal b can be emitted by the signal generator 5 located inside the first air guide 2. The emission direction of the detection signal b can always be towards the middle position of the first air outlet channel 13. When the first air guide 2 and the second air guide 3 rotate in the same direction, the first air guide 2 can guide air towards the first air outlet channel 13.

[0051] Step S2: When the detection signal is blocked by the first air guide, control the first air guide to stop rotating and control the second air guide to continue rotating.

[0052] Understandably, referring to Figures 3-6 As shown, when the direction of the detection signal b is parallel to the air guiding direction c of the first air guide 2 or the included angle α is less than the preset angle, the detection signal b can pass through the rotational movement area of ​​the first air guide 2, indicating that the misalignment between the first air guide 2 and the second air guide 3 is small and there is no risk of the air conditioner pinching your hand.

[0053] Reference Figure 7 As shown, when the angle α between the direction of the detection signal b and the air guiding direction c of the first air guide 2 is greater than or equal to the preset angle, the first air guide 2 blocks the detection signal b from passing through. This indicates that the first air guide 2 rotates too fast and the misalignment between the first air guide 2 and the second air guide 3 is large. If the first air guide 2 and the second air guide 3 continue to move, there is a risk of pinching a hand. Therefore, the first air guide 2 stops rotating, while the second air guide 3 continues to rotate, in order to reduce the misalignment between the first air guide 2 and the second air guide 3, thereby eliminating the risk of pinching a hand.

[0054] In some embodiments of the present invention, the preset angle ranges from 0° to 30°, for example, 10° or 22°.

[0055] According to the anti-pinch control method of the air conditioner according to the embodiment of the present invention, when the air conditioner is discharging air in three directions, it can determine whether the air conditioner has a risk of pinching fingers based on whether the detection signal b is blocked by the first air guide 2. When there is a risk of pinching fingers, the action of the first air guide 2 and the second air guide 3 is controlled to eliminate the risk of pinching fingers, thereby realizing the anti-pinch function of the air conditioner and improving the safety of the air conditioner.

[0056] In some embodiments of the present invention, when the detection signal b is not blocked by the first air guide 2, the method further includes: determining the rotation time t1 of the first air guide 2, and when the rotation time t1 of the first air guide 2 reaches a first preset time t 10 At that time, the first air guide 2 is controlled to stop rotating, while the second air guide 3 is controlled to continue rotating.

[0057] Understandably, assuming no risk of pinching fingers, the rotation time t1 of the first air guide 2 can be used to determine whether the first air guide 2 has rotated to its current rotational limit position. If the rotation time t1 of the first air guide 2 is greater than or equal to t... 10 This means that when the first air guide 2 rotates to the limit position in the current rotation direction, the rotation of the first air guide 2 can be stopped to prevent the first air guide 2 from rotating in the opposite direction after rotating to the limit position in the current rotation direction, and to prevent the first air guide 2 from rotating in the opposite direction to the second air guide 3, thereby avoiding the risk of pinching hands.

[0058] In some embodiments of the present invention, after controlling the first air guide 2 to stop rotating, the method further includes: determining the rotation time t2 of the second air guide 3, and determining the rotation time t2 of the second air guide 3 to reach a second preset time t. 20 At the same time, the first air guide 2 and the second air guide 3 are controlled to rotate in opposite directions simultaneously.

[0059] Understandably, after the first air guide 2 stops at its current rotational limit position, the rotation time t2 of the second air guide 3 is used to determine whether the second air guide 3 has reached its current rotational limit position. If the rotation time t2 of the second air guide 3 is ≥ t 20 This means that when the second air guide 3 rotates to the limit position of the current rotation direction, the first air guide 2 and the second air guide 3 can rotate in opposite directions at the same time, so as to achieve left and right sweeping of three-way air outlet while avoiding the risk of pinching hands.

[0060] In some embodiments of the present invention, reference is made to... Figures 3-8 As shown, a detection signal b is emitted by a signal generator 5. The signal generator 5 can be located inside the air outlet 11. The signal generator 5 can change the emission direction of the detection signal b by rotating around its own axis. When the air conditioner is venting air in three directions, the signal generator 5, the second air guide 3, and the first air guide 2 rotate in the same direction, so that the detection signal b is emitted towards the first air outlet channel 13. When the first air guide 2 and the second air guide 3 have a large misalignment, the first air guide 2 will block the detection signal b, thereby timely identifying the risk of pinching fingers.

[0061] In some specific embodiments of the present invention, the transmission direction of the detection signal b is always toward the middle position of the first air outlet channel 13. That is, when the detection signal b passes through the first air outlet channel 13 between the left air guide plate 31 and the right air guide plate 32, the distance between the detection signal b and the left air guide plate 31 is equal to the distance between the detection signal b and the right air guide plate 32.

[0062] In some embodiments of the present invention, reference is made to... Figures 3-7 As shown, the first air guide 2 includes multiple air guide strips 21. A signal receiver is provided on the air guide strip 21 that is adapted to the position of the signal generator 5. When the detection signal b emitted by the signal generator 5 falls into the signal receiver, the signal receiver can receive the detection signal b, thereby determining that the detection signal b is blocked by the first air guide 2.

[0063] It should be noted that the signal receiver can be located on the middle air guide strip 21 that guides airflow towards the center of the first air outlet duct 13. For example, the first air guide 2 includes first to fifth air guide strips arranged sequentially from left to right, and the signal receiver can be located on the third air guide strip located in the middle. When there is three-way airflow and no risk of pinching, if the airflow direction c of the air guide strip 21 with the signal receiver is parallel to the direction of the detection signal b emitted by the signal generator 5 or the angle α is less than a preset angle, the detection signal b fails to fall on the air guide strip 21 with the signal receiver, and the signal receiver does not receive the detection signal b. When there is three-way airflow and a risk of pinching, if the angle α between the airflow direction c of the air guide strip 21 with the signal receiver and the direction of the detection signal b emitted by the signal generator 5 is greater than or equal to a preset angle, the detection signal b falls on the air guide strip 21 with the signal receiver, and the signal receiver receives the detection signal b. The signal receiver can be located on one side of the air guide strip 21.

[0064] In some embodiments of the present invention, reference is made to... Figure 3 As shown, the detection signal b passes through the middle two adjacent air guides 21 among the multiple air guides 21, and the distance S between the projection point of the signal generator 5 on the vertical plane formed by the middle two adjacent air guides 21 and the middle air guide 21 satisfies the relationship: H / 3 < S < H / 2, where H is the interval between the middle two adjacent air guides 21, for example, S = 5H / 12, and a signal receiver is provided on the middle air guide 21.

[0065] If the distance S between the signal generator 5 and the intermediate air guide 21 is greater than or equal to H / 2, the signal generator 5 is prone to failure. Even if the misalignment between the first air guide 2 and the second air guide 3 is too large, the signal receiver will not be able to receive the signal, resulting in the anti-pinch function being insensitive. If the distance S between the signal generator 5 and the intermediate air guide 21 is less than or equal to H / 3, the signal receiver is prone to misjudgment. Even if the misalignment between the first air guide 2 and the second air guide 3 is small, the signal receiver will still receive the signal, causing the anti-pinch function to give false alarms. This will cause the first air guide 2 to frequently stop rotating, affecting the air guiding effect and user experience.

[0066] In some embodiments of the present invention, the rotational angular velocity ω1 of the first air guide 2 is greater than the rotational angular velocity ω3 of the signal generator 5, and the rotational angular velocity ω3 of the signal generator 5 is greater than the rotational angular velocity ω2 of the second air guide 3. Since the rotational axes around which the first air guide 2, the second air guide 3, and the signal generator 5 move are different, when the air conditioner is discharging air in three directions, in order to ensure that the misalignment between the first air guide 2 and the second air guide 3 is small, and that the transmission direction of the detection signal b is always towards the middle position of the first air outlet channel 13, ω1 > ω3 > ω2. It can be understood that the closer the rotational axis around which the first air guide 2, the second air guide 3, and the signal generator 5 move is to the rear of the air conditioner, the smaller their rotational angular velocity is.

[0067] Figure 2 A flowchart of an anti-pinch control method according to another embodiment of the present invention is shown below. Figure 2 As shown, the method includes the following steps:

[0068] Step S11: Switch the air conditioner to three-way airflow mode.

[0069] Step S12: Determine whether the first air guide and the second air guide are in their default positions. If yes, proceed to step S14; otherwise, proceed to step S13.

[0070] Among them, reference Figure 3 As shown, in the default position, the air guiding direction c of the first air guide 2 is towards the front of the air conditioner, and the first air outlet duct 13 can discharge air to the front of the air conditioner.

[0071] Step S13: Control the first air guide and the second air guide to rotate to the default position.

[0072] In step S14, the first air guide component rotates in the same direction with a rotational angular velocity of ω1, the second air guide component rotates with a rotational angular velocity of ω2, and the signal generator rotates with a rotational angular velocity of ω3.

[0073] Step S15: Determine whether the signal receiver on the first air guide has received the detection signal emitted by the signal generator. If yes, proceed to step S17; otherwise, proceed to step S16.

[0074] Step S16: Determine if the rotation time t1 of the first air guide component is greater than or equal to t. 10 If yes, proceed to step S17; otherwise, return to step S14.

[0075] Among them, t 10 =θ1 / ω1,t 10 For the first preset time, θ1 is the maximum rotation angle of the first air guide 2 on one side, and ω1 is the rotational angular velocity of the first air guide 2. When t1≥t 10 At that time, the first air guide 2 moves to the limit position of the current rotation direction.

[0076] In step S17, the first air guide stops rotating, while the second air guide continues to rotate in the same direction with a rotational angular velocity of ω2 and the signal generator with a rotational angular velocity of ω3.

[0077] Step S18: Determine if the rotation time t2 of the second air guide is greater than or equal to t. 20 If yes, proceed to step S19; otherwise, return to step S15.

[0078] Among them, t 20 =θ2 / ω2,t 20For the second preset time, θ2 is the maximum rotation angle of the second air guide 3 on one side, and ω2 is the rotational angular velocity of the second air guide 3. When t2≥t 20 At that time, the second air guide 3 moves to the limit position of the current rotation direction.

[0079] In step S19, the first air guide component rotates in opposite directions simultaneously with a rotational angular velocity of ω1, the second air guide component rotates with a rotational angular velocity of ω2, and the signal generator rotates with a rotational angular velocity of ω3, and then returns to step S15.

[0080] According to the anti-pinch control method of the air conditioner according to the embodiment of the present invention, when the air conditioner is discharging air in three directions, it can determine whether the air conditioner has a risk of pinching fingers based on whether the detection signal b is blocked by the first air guide 2. When there is a risk of pinching fingers, the operation of the first air guide 2 and the second air guide 3 is controlled to avoid large misalignment between the first air guide 2 and the second air guide 3, and to prevent the first air guide 2 and the second air guide 3 from rotating in opposite directions, thereby eliminating the risk of pinching fingers, and thus realizing the anti-pinch function of the air conditioner and improving the safety of the air conditioner.

[0081] The following is combined with Figures 3-8 A detailed description of an air conditioner with anti-pinch function according to an embodiment of the present invention.

[0082] Reference Figures 3-8 As shown, the air conditioner includes a housing 1, a first air guide 2, a second air guide 3, a first air guide drive device, a second air guide drive device 4, a signal generator 5, and a signal receiver, wherein:

[0083] The air conditioner can be a cabinet air conditioner. The housing 1 is provided with an air outlet 11 and an air inlet 12. The air outlet 11 and the air inlet 12 are connected by a duct component 6. A heat exchanger 7 is also provided between the duct component 6 and the air inlet 12. The duct component 6 includes a fan wheel 61 and a swing blade 62. The fan wheel 61 can be a cross-flow fan wheel 61. The fan wheel 61 can be used to provide air pressure. The swing blade 62 can be used to adjust the air outlet direction in the vertical direction.

[0084] The first air guide 2 is movably disposed at the air outlet 11. That is to say, the first air guide 2 can be disposed at the outlet of the air duct component 6. The first air guide 2 can be used to adjust the air outlet direction in the left and right directions.

[0085] The first air guide drive device works in conjunction with the first air guide component 2. The first air guide drive device can drive the first air guide component 2 to rotate around the vertical axis. The first air guide drive device can be a motor gear mechanism.
