Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a mobile air conditioner and an intelligent air swing control method thereof. Background Art

[0002] During operation, mobile air conditioners are limited by factors such as the ambient space, internal air ducts, and fan motors. Each model has a maximum air delivery distance—the maximum distance a person standing directly in front of the unit's air outlet can feel the air. In theory, higher fan speeds increase the air delivery distance, but this also comes with the added problem of increased noise, so product development requires a balance between these two parameters. The greatest advantage of mobile air conditioners is their mobility, allowing for a wide range of applications, with most units being moved manually. Furthermore, to improve cooling efficiency, the fan at the bottom of the unit must be connected to an exhaust duct, securing it to the outside to dissipate heat. While mobile air conditioners are inherently mobile, the air outlet typically uses a vertical oscillation mechanism during operation. While complex designs can achieve both horizontal and vertical oscillation, the structural limitations prevent wide angles, resulting in a poor user experience and a lack of comfortable airflow.

Figure 8 1 is a partial structural diagram of the back of a mobile air conditioner provided in one embodiment of the present invention. The mobile air conditioner 100 provided in the embodiment of the present invention includes:

[0056] A housing 1 is provided with a first air inlet 11, an air outlet 12, a second air inlet, and an air outlet. The first air inlet 11 and the air outlet 12 are connected to form an indoor air duct, and the second air inlet and the air outlet are connected to form an outdoor air duct.

[0057] An indoor unit, comprising a first heat exchanger 2 and a first fan 3, wherein the first heat exchanger 2 and the first fan 3 are arranged in the indoor air duct;

[0058] An outdoor unit, comprising a compressor 7, a second heat exchanger 8 and a second fan 9, wherein the compressor 7, the second heat exchanger 8 and the second fan 9 are arranged in the outdoor air duct;

[0059] An exhaust tube 10, wherein the exhaust tube 10 is detachably mounted at the exhaust port;

[0060] A first displacement sensor 13, which is installed on the left side of the exhaust cylinder 10;

[0061] A second displacement sensor 14, which is installed on the right side of the exhaust cylinder 10;

[0062] The controller is configured to, when the mobile air conditioner 100 is in the horizontal circulation swing mode, determine the size relationship between the first detection value of the first displacement sensor 13 and the second detection value of the second displacement sensor 14; calculate the target displacement distance of the first displacement sensor 13 or the second displacement sensor 14 based on the determination result and the cylinder diameter length of the exhaust duct 10, and control the mobile air conditioner 100 to rotate to a target angle based on the target displacement distance.

[0063] Specifically, the mobile air conditioner 100 in the embodiment of the present invention has an indoor unit and an outdoor unit of a heat cycle installed together in a housing. Usually, the upper half is the indoor unit and the lower half is the outdoor unit, which is usually also called an integrated air conditioner or a unitary air conditioner.

[0064] The mobile air conditioner 100 includes a refrigeration system disposed within a housing 1 of the mobile air conditioner for powering the refrigeration cycle of the mobile air conditioner 100. The refrigeration system includes a first heat exchanger 2, a first fan 3, a compressor 7, a second heat exchanger 8, a second fan 9, and a capillary tube (not shown). A first chamber 4 and a second chamber 6 are formed within the housing 1. The second chamber 6 is located below the first chamber 4. The first heat exchanger 2 and the first fan 3 are disposed within the first chamber 4. The compressor 7, the second heat exchanger 8, and the second fan 9 are disposed within the second chamber 6.

[0065] The housing 1 has a first air inlet 11 and an air outlet 12 that are connected to the first chamber 4. The air outlet 12 is tilted upward relative to the horizontal plane. The housing 1 includes a single-side shell plate and a rear shell plate adjacent to each other. The first air inlet 11 and the second air inlet are respectively provided on the single-side shell plate and the rear shell plate; correspondingly, the first heat exchanger 2 includes a first plate portion 21 and a second plate portion 22, which respectively cover the two air inlets. Based on this, the first heat exchanger 2 that covers both air inlets has a larger heat exchange area, which can improve the working efficiency of the mobile air conditioner. The single-side shell plate and the rear shell plate of the housing 1 are perpendicular to each other, and the first plate portion 21 and the second plate portion 22 of the first heat exchanger 2 are perpendicular to each other, that is, the first heat exchanger 2 is L-shaped. The first fan 3 is a horizontally arranged centrifugal fan that draws air in through the first air inlet 11, passes it through the first heat exchanger 2, and then blows it out through the air outlet 12. The first fan 3 has a fan inlet and a fan outlet, and the orientation of the fan outlet coincides with the orientation of the air outlet 12. The air outlet 12 is provided with a rotatable air guide plate 5. By rotating the air guide plate 5, the user can adjust the airflow direction of the air outlet 12 to meet usage requirements.

[0066] The fan inlet of the first fan 3 faces the first heat exchanger 2, and the first heat exchanger 2 covers the first air inlet 11 from within the housing 1, ensuring that new air entering the first chamber 4 through the first air inlet 11 can immediately pass through the first heat exchanger 2, enhancing its heat exchange efficiency. The first fan 3 has a partition 31 extending from the periphery of its fan inlet to the first heat exchanger 2, separating the first fan 3 from the first heat exchanger 2. New air entering the first chamber 4 through the first air inlet 11, after passing through the first heat exchanger 2, is guided by the partition 31 and then enters the fan inlet of the first fan 3, thereby increasing the ventilation volume of the first fan 3. The compressor 7 is connected to the first heat exchanger 2 and the second heat exchanger 8 via pipelines. The second fan 9 is a vertically arranged centrifugal fan that draws external air into the second chamber 6 and allows it to flow through the second heat exchanger 8 before being discharged outside the housing 1. The second fan 9 drives the air flow from the second air inlet into the outdoor air duct to exchange heat with the second heat exchanger 8, and then discharged from the exhaust port.

[0067] During use, the mobile air conditioner requires an external exhaust duct 10, which is removably mounted at the exhaust port. This duct 10 discharges heat generated by the mobile air conditioner through the second fan 9 and is extendable, but its maximum length cannot exceed 170 cm. Displacement sensors, namely a first displacement sensor 13 and a second displacement sensor 14, are mounted on the left and right sides of the exhaust duct 10, respectively, to detect the extended length of the exhaust duct 10 in real time.

[0068] The controller is configured to, when the mobile air conditioner 100 is in the horizontal circulation swing mode, determine the magnitude relationship between the first detection value RealLengthLeft of the first displacement sensor 13 and the second detection value RealLengthR of the second displacement sensor 14. Based on the determination result and the cylinder diameter length LengthR of the exhaust cylinder 10, the controller calculates a target displacement distance for the first displacement sensor 13 or the second displacement sensor 14, and controls the mobile air conditioner 100 to rotate to a target angle based on the target displacement distance.

[0069] It should be noted that, because the air outlet design of the mobile air conditioner in the embodiment of the present invention is to swing wind up and down, that is, longitudinally swing wind, but cannot realize the left and right swing wind function, that is, horizontally swing wind, the embodiment of the present invention adds a horizontal swing wind mode, which requires the user to preset this mode.

[0070] The embodiment of the present invention controls the movable trajectory distance of the entire machine by real-time detection of the stretched length of the exhaust duct without increasing the cost, increases the air supply angle of the mobile air conditioner, and effectively improves the user experience.

[0071] As one of the optional embodiments, the first displacement sensor 13 and the second displacement sensor 14 are both pull-rope displacement sensors, one end of the pull-rope displacement sensor is installed at one end of the exhaust duct 10, and the other end of the pull-rope displacement sensor is installed at the other end of the exhaust duct 10 through a hook.

[0072] For details, please refer to Figure 7 and Figure 8 In the embodiment of the present invention, the first displacement sensor and the second displacement sensor are both rope displacement sensors. One end of the rope displacement sensor is installed at one end of the exhaust duct, and the other end of the rope displacement sensor is installed at the other end of the exhaust duct through a hook. When the machine body moves, the rope will stretch or contract, changing the length of the rope. The device on the pulley will detect the change in the rope, and then transmit the signal to the measurement circuit inside the sensor, and finally output the measurement result through the output interface. During use, the user must first install the exhaust duct and connect the rope hook of the displacement sensor to the other end of the exhaust duct. If the user does not connect the exhaust duct during use, the displacement state will not be determined at this time, and the cooling effect of the entire machine will be affected because the heat cannot be discharged to the outdoor side.

[0073] As one of the optional embodiments, the controller is further configured to:

[0074] When the mobile air conditioner 100 is in the horizontal circulation swing mode, determining whether the first detection value of the first displacement sensor 13 is greater than zero;

[0075] If not, it is determined that the first displacement sensor 13 is not installed in place or the exhaust duct 10 is not installed; if so, it is determined that the first displacement sensor 13 is installed in place, and the second detection value of the second displacement sensor 14 is further determined to be greater than zero;

[0076] If not, it is determined that the second displacement sensor 14 is not installed in place or the exhaust duct 10 is not installed; if so, it is determined that the second displacement sensor 14 is installed in place.

[0077] Specifically, in an embodiment of the present invention, when the mobile air conditioner is in the horizontal circulation swing mode, it is determined whether the first detection value RealLength Left of the first displacement sensor is greater than zero (greater than 0 indicates that the hook of the pull-cord displacement sensor has been hooked to the end of the air duct). If not, it is determined that the first displacement sensor is not installed in place or the exhaust duct is not installed, and the display panel digital tube displays "EE", indicating that the exhaust duct is not installed (the exhaust duct is not fixed), and the entire machine stops moving; if so, it is determined that the first displacement sensor is installed in place, and it is further determined whether the second detection value RealLength Right of the second displacement sensor is greater than zero; if not, it is determined that the second displacement sensor is not installed in place or the exhaust duct is not installed, and the display panel digital tube displays "EE", indicating that the exhaust duct is not installed (the exhaust duct is not fixed), and the entire machine stops moving; if so, it is determined that the second displacement sensor is installed in place.

[0078] As one of the optional embodiments, the step of calculating a target displacement distance of the first displacement sensor 13 or the second displacement sensor 14 based on the judgment result and the diameter of the exhaust duct 10, and controlling the mobile air conditioner 100 to rotate to a target angle based on the target displacement distance, specifically includes:

[0079] If the first detection value is equal to the second detection value, calculating the first target displacement distance of the first displacement sensor or the second displacement sensor according to the cylinder diameter length of the exhaust cylinder;

[0080] The mobile air conditioner is controlled to rotate until the first detection value or the second detection value is equal to the first target displacement distance, and then the mobile air conditioner is rotated to a target angle.

[0081] Specifically, in this embodiment of the present invention, when the mobile air conditioner 100 is in horizontal circulation swing mode, the magnitude relationship between the first detection value RealLength (left) of the first displacement sensor 13 and the second detection value RealLength (right) of the second displacement sensor 14 is determined. If the first detection value RealLength (left) equals the second detection value RealLength (right), it indicates that the exhaust duct is positioned perpendicular to the back of the air conditioner body and is not bent. The first target displacement distance of the first displacement sensor or the second displacement sensor is calculated based on the exhaust duct diameter length LengthR. For example, the target displacement distance calculation formula is:

[0082] Length target = Length R * 2 * π) * 1 / 4.

[0083] After calculating the first target displacement distance for the first or second displacement sensor, the mobile air conditioner is controlled to rotate until the first detection value (RealLength Left) or the second detection value (RealLength Right) equals the first target displacement distance, at which point the mobile air conditioner is rotated to the target angle. It should be noted that the Length target limits the maximum left-right rotation angle of the entire unit to no more than 90°. Exceeding 90° can cause severe deformation due to the exhaust duct's inherent material, so this maximum rotation angle limit is implemented.

[0084] For example, when the exhaust duct is perpendicular to the back of the machine, the calculated target Length value is 1 / 4 of the circumference. Assuming the machine starts at point A, with the left side of the chassis roller moving forward and the right side stationary, when the machine rotates 90°, the exhaust duct bends, causing the detection distance RealLength Left of the first displacement sensor on the left to equal the target Length value. Similarly, starting from point B, the detection distance RealLength Right of the second displacement sensor on the right should equal the target Length value.

[0085] See also Figure 9 , Figure 9 This is a first workflow diagram of a controller in a mobile air conditioner provided by one embodiment of the present invention. For example, when the first detection value, RealLength Left, equals the second detection value, RealLength Right, i.e., the exhaust duct is perpendicular to the back of the machine body, the first target displacement distance, Length Target, of the first displacement sensor or the second displacement sensor is calculated based on the exhaust duct diameter length, Length R. The right roller on the entire chassis moves forward (four rollers are placed at the bottom of the machine body, driven by a motor that can move in two directions, namely forward and backward). The displacement sensor detection values, RealLength Left and RealLength Right, are acquired in real time. ChaValue Right = RealLength Right - RealLengthBackup Right (calculating the difference between the right displacement sensor at the current right shift and the initial value) is calculated. A determination is made as to whether ChaValue Right is greater than or equal to Length Target. If so, the right roller stops moving forward. The right roller moves backward. When RealLength Right is less than or equal to RealLengthBackup Right, the right roller stops moving, and the machine returns to its initial state. Continue to move the left single roller forward, calculate ChaValue left = RealLength left - RealLengthBackup left, when ChaValue left is greater than or equal to the target Length, stop the left single roller moving forward, and move the left single roller backward. When RealLength left is less than or equal to RealLengthBackup left, stop the left single roller moving, and the entire machine returns to its initial state.

[0086] As one of the optional embodiments, the step of calculating a target displacement distance of the first displacement sensor 13 or the second displacement sensor 14 based on the judgment result and the diameter of the exhaust duct 10, and controlling the mobile air conditioner 100 to move to a target angle based on the target displacement distance, specifically includes:

[0087] If the first detection value is not equal to the second detection value, determining whether the first detection value is greater than the second detection value;

[0088] If so, the second detection value is used as an initial starting point, and a second target displacement distance of the first displacement sensor 13 or the second displacement sensor 14 is calculated according to the cylinder diameter length of the exhaust cylinder 10, and the mobile air conditioner 100 is controlled to rotate until the first detection value or the second detection value is equal to the second target displacement distance, and the mobile air conditioner 100 is rotated to the target angle;

[0089] If not, the first detection value is used as the initial starting point, and the third target displacement distance of the first displacement sensor 13 or the second displacement sensor 14 is calculated according to the cylinder diameter length of the exhaust duct 10, and the mobile air conditioner 100 is controlled to rotate until the first detection value or the second detection value is equal to the third target displacement distance, and the mobile air conditioner 100 rotates to the target angle.

[0090] Specifically, in this embodiment of the present invention, when the mobile air conditioner 100 is in horizontal circulation swing mode, the magnitude relationship between the first detection value RealLength Left of the first displacement sensor 13 and the second detection value RealLength Right of the second displacement sensor 14 is determined. If the first detection value RealLength Left is not equal to the second detection value RealLength Right, it indicates that the exhaust duct is not perpendicular to the back of the air conditioner body and is bent. In this case, it is necessary to first determine which side of the exhaust duct is closer to the air conditioner body and then determine whether the first detection value RealLength Left is greater than the second detection value RealLength Right.

[0091] If the first detected value, RealLength Left, is greater than the second detected value, RealLength Right, this indicates that the right side of the exhaust duct has been stretched closer to the machine body. Using the second detected value, RealLength Right, as the initial starting point, set RealLength Right = RealLength Left, and pull the right side back to a level with the left side, restoring the machine body to a point where the exhaust duct is perpendicular to the back of the machine body. The second target displacement distance of the first or second displacement sensor is calculated based on the exhaust duct diameter, Length R, and the mobile air conditioner is controlled to rotate until the first detected value, RealLength Left, or the second detected value, RealLength Right, equals the second target displacement distance, at which point the mobile air conditioner rotates to the target angle.

[0092] If the first detected value, RealLength Left, is less than the second detected value, RealLength Right, it indicates that the stretched length of the left side of the exhaust duct is closer to the machine body. Using the first detected value, RealLength Left, as the initial starting point, set RealLength Left = RealLength Right, and pull the left side back to a level with the right side, restoring the machine body to a point where the exhaust duct is perpendicular to the back of the machine body. The third target displacement distance of the first or second displacement sensor is calculated based on the exhaust duct diameter, LengthR, and the mobile air conditioner is controlled to rotate until the first detected value, RealLength Left, or the second detected value, RealLength Right, equals the third target displacement distance, at which point the mobile air conditioner rotates to the target angle.

[0093] For example, if the exhaust duct is not perpendicular to the back of the machine, it is necessary to first determine which side of the exhaust duct is closer to the machine. Once the closer side is determined, the closer side is used as the initial starting point to calculate the target Length value. The machine is then restored to the point where the exhaust duct is perpendicular to the back of the machine, and a 90° left and 90° right swing is performed. The swing process follows the same logic as when RealLengthLeft equals RealLengthRight.

[0094] See also Figure 10 , Figure 10This is a second workflow diagram for a controller in a mobile air conditioner provided by one embodiment of the present invention. For example, when the first detection value, RealLength Left, is not equal to the second detection value, RealLength Right, meaning the exhaust duct is not positioned perpendicular to the back of the air conditioner and is bent, it is necessary to first determine which side of the exhaust duct is closer to the air conditioner by its stretched length, and then determine whether the first detection value, RealLength Left, is greater than the second detection value, RealLength Right. If RealLength Left is greater than RealLength Right, the subsequent control logic is the same as when RealLength Left is equal to RealLength Right. If RealLength Left is less than RealLength Right, the control logic for roller movement is essentially the same as when RealLength Left is equal to RealLength Right, with the difference being that the left roller is first moved forward, then backward, then the left roller is moved forward, then the right roller is moved backward (the left side is moved first because RealLength Right is greater than RealLength Left during the initial movement, indicating that the right side is closer to the front on the X-axis horizontal line, so the left roller is moved first to the target distance).

[0095] See also Figure 11 , Figure 11 The figure is a flow chart of a method for intelligent air swing control for a mobile air conditioner according to one embodiment of the present invention. The method is applied to a mobile air conditioner comprising a housing, an indoor unit, an outdoor unit, an exhaust duct, a first displacement sensor, and a second displacement sensor. The exhaust duct is detachably mounted at an exhaust port, the first displacement sensor is mounted on the left side of the exhaust duct, and the second displacement sensor is mounted on the right side of the exhaust duct. The method comprises:

[0096] S1, when the mobile air conditioner is in a horizontal circulation swing mode, determining a magnitude relationship between a first detection value of the first displacement sensor and a second detection value of the second displacement sensor;

[0097] S2, calculating a target displacement distance of the first displacement sensor or the second displacement sensor according to the judgment result and the diameter of the exhaust tube, and controlling the mobile air conditioner to rotate to a target angle according to the target displacement distance.

[0098] Specifically, in this embodiment of the present invention, when the mobile air conditioner is in horizontal circulation swing mode, a magnitude relationship between a first detection value (RealLength Left) of the first displacement sensor and a second detection value (RealLength Right) of the second displacement sensor is determined. A target displacement distance of the first displacement sensor or the second displacement sensor is calculated based on the determination result and the exhaust cylinder diameter length (LengthR). The mobile air conditioner is then controlled to rotate to a target angle based on the target displacement distance.

[0099] It should be noted that, because the air outlet design of the mobile air conditioner in the embodiment of the present invention is to swing wind up and down, that is, longitudinally swing wind, but cannot realize the left and right swing wind function, that is, horizontally swing wind, the embodiment of the present invention adds a horizontal swing wind mode, which requires the user to preset this mode.

[0100] The embodiment of the present invention controls the movable trajectory distance of the entire machine by real-time detection of the stretched length of the exhaust duct without increasing the cost, increases the air supply angle of the mobile air conditioner, and effectively improves the user experience.

[0101] As one of the optional embodiments, the first displacement sensor and the second displacement sensor are both pull-wire displacement sensors, one end of the pull-wire displacement sensor is installed at one end of the exhaust duct, and the other end of the pull-wire displacement sensor is installed at the other end of the exhaust duct through a hook.

[0102] Specifically, in the embodiment of the present invention, the first displacement sensor and the second displacement sensor are both rope displacement sensors, one end of the rope displacement sensor is installed at one end of the exhaust duct, and the other end of the rope displacement sensor is installed at the other end of the exhaust duct via a hook. When the machine body moves, the rope will stretch or contract, changing the length of the rope. The device on the pulley will detect the change in the rope, and then transmit the signal to the measurement circuit inside the sensor, and finally output the measurement result through the output interface. During use, the user must first install the exhaust duct and connect the rope hook of the displacement sensor to the other end of the exhaust duct. If the user does not connect the exhaust duct during use, the displacement state will not be determined at this time, and the cooling effect of the entire machine will be affected because the heat cannot be discharged to the outdoor side.

[0103] As an optional embodiment, the method further includes:

[0104] When the mobile air conditioner is in a horizontal circulation swing mode, determining whether a first detection value of the first displacement sensor is greater than zero;

[0105] If not, it is determined that the first displacement sensor is not installed in place or the exhaust duct is not installed; if so, it is determined that the first displacement sensor is installed in place, and the second detection value of the second displacement sensor is further determined to be greater than zero;

[0106] If not, it is determined that the second displacement sensor is not installed in place or the exhaust duct is not installed; if so, it is determined that the second displacement sensor is installed in place.

[0107] Specifically, in an embodiment of the present invention, when the mobile air conditioner is in the horizontal circulation swing mode, it is determined whether the first detection value RealLength Left of the first displacement sensor is greater than zero (greater than 0 indicates that the hook of the pull-cord displacement sensor has been hooked to the end of the air duct). If not, it is determined that the first displacement sensor is not installed in place or the exhaust duct is not installed, and the display panel digital tube displays "EE", indicating that the exhaust duct is not installed (the exhaust duct is not fixed), and the entire machine stops moving; if so, it is determined that the first displacement sensor is installed in place, and it is further determined whether the second detection value RealLength Right of the second displacement sensor is greater than zero; if not, it is determined that the second displacement sensor is not installed in place or the exhaust duct is not installed, and the display panel digital tube displays "EE", indicating that the exhaust duct is not installed (the exhaust duct is not fixed), and the entire machine stops moving; if so, it is determined that the second displacement sensor is installed in place.

[0108] As one of the optional embodiments, calculating a target displacement distance of the first displacement sensor or the second displacement sensor based on the judgment result and the diameter length of the exhaust duct, and controlling the mobile air conditioner to rotate to a target angle based on the target displacement distance specifically includes:

[0109] If the first detection value is equal to the second detection value, calculating the first target displacement distance of the first displacement sensor or the second displacement sensor according to the cylinder diameter length of the exhaust cylinder;

[0110] The mobile air conditioner is controlled to rotate until the first detection value or the second detection value is equal to the first target displacement distance, and then the mobile air conditioner is rotated to a target angle.

[0111] Specifically, in an embodiment of the present invention, when the mobile air conditioner is in horizontal circulation swing mode, the magnitude relationship between the first detection value RealLength (left) of the first displacement sensor and the second detection value RealLength (right) of the second displacement sensor is determined. If the first detection value RealLength (left) equals the second detection value RealLength (right), it indicates that the exhaust duct is positioned perpendicular to the back of the air conditioner body and is not bent. The first target displacement distance of the first displacement sensor or the second displacement sensor is calculated based on the exhaust duct diameter length LengthR. For example, the target displacement distance calculation formula is:

[0112] Length target = Length R * 2 * π) * 1 / 4.

[0113] After calculating the first target displacement distance for the first or second displacement sensor, the mobile air conditioner is controlled to rotate until the first detection value (RealLength Left) or the second detection value (RealLength Right) equals the first target displacement distance, at which point the mobile air conditioner is rotated to the target angle. It should be noted that the Length target limits the maximum left-right rotation angle of the entire unit to no more than 90°. Exceeding 90° can cause severe deformation due to the exhaust duct's inherent material, so this maximum rotation angle limit is implemented.

[0114] For example, when the exhaust duct is perpendicular to the back of the machine, the calculated target Length value is 1 / 4 of the circumference. Assuming the machine starts at point A, with the left side of the chassis roller moving forward and the right side stationary, when the machine rotates 90°, the exhaust duct bends, causing the detection distance RealLength Left of the first displacement sensor on the left to equal the target Length value. Similarly, starting from point B, the detection distance RealLength Right of the second displacement sensor on the right should equal the target Length value.

[0115] As one of the optional embodiments, calculating a target displacement distance of the first displacement sensor or the second displacement sensor based on the judgment result and the diameter length of the exhaust duct, and controlling the mobile air conditioner to move to a target angle based on the target displacement distance specifically includes:

[0116] If the first detection value is not equal to the second detection value, determining whether the first detection value is greater than the second detection value;

[0117] If so, taking the second detection value as an initial starting point, calculating a second target displacement distance of the first displacement sensor or the second displacement sensor according to the cylinder diameter length of the exhaust cylinder, and controlling the mobile air conditioner to rotate until the first detection value or the second detection value is equal to the second target displacement distance, and then rotating the mobile air conditioner to a target angle;

[0118] If not, the first detection value is used as the initial starting point, and the third target displacement distance of the first displacement sensor or the second displacement sensor is calculated according to the cylinder diameter length of the exhaust duct, and the mobile air conditioner is controlled to rotate until the first detection value or the second detection value is equal to the third target displacement distance, and the mobile air conditioner rotates to the target angle.

[0119] Specifically, in this embodiment of the present invention, when the mobile air conditioner is in horizontal circulation swing mode, the magnitude relationship between the first detection value (RealLength Left) of the first displacement sensor and the second detection value (RealLength Right) of the second displacement sensor is determined. If the first detection value (RealLength Left) is not equal to the second detection value (RealLength Right), it indicates that the exhaust duct is not positioned perpendicular to the back of the air conditioner body and is bent. In this case, it is necessary to first determine which side of the exhaust duct is closer to the air conditioner body and then determine whether the first detection value (RealLength Left) is greater than the second detection value (RealLength Right).

[0120] If the first detected value, RealLength Left, is greater than the second detected value, RealLength Right, this indicates that the right side of the exhaust duct has been stretched closer to the machine body. Using the second detected value, RealLength Right, as the initial starting point, set RealLength Right = RealLength Left, and pull the right side back to a level with the left side, restoring the machine body to a point where the exhaust duct is perpendicular to the back of the machine body. The second target displacement distance of the first or second displacement sensor is calculated based on the exhaust duct diameter, Length R, and the mobile air conditioner is controlled to rotate until the first detected value, RealLength Left, or the second detected value, RealLength Right, equals the second target displacement distance, at which point the mobile air conditioner rotates to the target angle.

[0121] If the first detected value, RealLength Left, is less than the second detected value, RealLength Right, it indicates that the stretched length of the left side of the exhaust duct is closer to the machine body. Using the first detected value, RealLength Left, as the initial starting point, set RealLength Left = RealLength Right, and pull the left side back to a level with the right side, restoring the machine body to a point where the exhaust duct is perpendicular to the back of the machine body. The third target displacement distance of the first or second displacement sensor is calculated based on the exhaust duct diameter, LengthR, and the mobile air conditioner is controlled to rotate until the first detected value, RealLength Left, or the second detected value, RealLength Right, equals the third target displacement distance, at which point the mobile air conditioner rotates to the target angle.

[0122] For example, if the exhaust duct is not perpendicular to the back of the machine, it is necessary to first determine which side of the exhaust duct is closer to the machine. Once the closer side is determined, the closer side is used as the initial starting point to calculate the target Length value. The machine is then restored to the point where the exhaust duct is perpendicular to the back of the machine, and a 90° left and 90° right swing is performed. The swing process follows the same logic as when RealLengthLeft equals RealLengthRight.

[0123] An embodiment of the present invention provides a mobile air conditioner and an intelligent air swing control method thereof. A first displacement sensor and a second displacement sensor are installed on the left and right sides of the exhaust duct, respectively, to detect the stretched length of the exhaust duct in real time. When the mobile air conditioner is in horizontal circulation swing mode, the magnitude relationship between the first detection value of the first displacement sensor and the second detection value of the second displacement sensor is determined. The target displacement distance of the first displacement sensor or the second displacement sensor is calculated based on the determination result and the diameter of the exhaust duct, and the mobile air conditioner is controlled to rotate to a target angle based on the target displacement distance. Without increasing costs, the embodiment of the present invention controls the movable trajectory distance of the entire unit by detecting the stretched length of the exhaust duct in real time, thereby increasing the air supply angle of the mobile air conditioner and effectively improving the user experience.
