Mobile air conditioner and intelligent air supply control method thereof

Abstract

The present invention discloses a mobile air conditioner and an intelligent air supply control method thereof. The mobile air conditioner includes a housing, an indoor unit, an outdoor unit, an exhaust duct, a displacement sensor, and a controller. The controller is configured to control the mobile air conditioner to move rightward when the mobile air conditioner is in a horizontal air supply mode. If the detection value of the displacement sensor reaches the maximum stretch length of the displacement sensor, the controller stops moving rightward and starts moving leftward until the detection value reaches the maximum stretch length and stops moving leftward. When the mobile air conditioner is in a longitudinal air supply mode, the controller controls the mobile air conditioner to move forward. If the detection value reaches the maximum stretch length, the controller stops moving forward and starts moving backward until the detection value reaches the initial minimum distance of the displacement sensor and stops moving backward. Without increasing costs, the present invention controls the movable trajectory distance of the entire unit by real-time detecting the stretch length of the exhaust duct, thereby increasing the air supply distance and air supply angle of the mobile air conditioner and effectively improving the user experience.

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 supply 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 can feel the air blown. In theory, higher fan speeds increase the air delivery distance, but this also comes with the added problem of increased noise. Therefore, product development requires a balance between these two parameters. The greatest advantage of mobile air conditioners is their mobility, which allows for a wide range of applications, with most units being moved manually. Furthermore, to improve cooling efficiency, the lower fan of the unit must be connected to an exhaust duct, secured to the outside, to dissipate heat. While mobile air conditioners are inherently mobile, the exhaust duct must be connected to the outside during operation. Due to the duct's length, this prevents true mobility and requires movement within a safe range. Otherwise, the duct could be damaged. Furthermore, if the room is large, exceeding the air conditioner's maximum air delivery distance and angle will result in a poor user experience and a lack of comfortable airflow. Summary of the Invention

Figure 7 1 is a schematic diagram of the back structure 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 displacement sensor 13 is mounted on the exhaust cylinder 10 and is used to detect the telescopic length of the exhaust cylinder 10;

[0061] The controller is configured to, when the mobile air conditioner 100 is in the horizontal air supply mode, control the mobile air conditioner 100 to move to the right and obtain the detection value of the displacement sensor 13 in real time; if the detection value reaches the maximum stretching length of the displacement sensor 13, control the mobile air conditioner 100 to stop moving to the right and start moving to the left until the detection value reaches the maximum stretching length, and control the mobile air conditioner 100 to stop moving to the left; when the mobile air conditioner 100 is in the longitudinal air supply mode, control the mobile air conditioner 100 to move forward and obtain the detection value of the displacement sensor 13 in real time; if the detection value reaches the maximum stretching length, control the mobile air conditioner 100 to stop moving forward and start moving backward until the detection value reaches the initial minimum distance of the displacement sensor 13, and control the mobile air conditioner 100 to stop moving backward.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] During use, the mobile air conditioner requires an external exhaust duct 10, which is removably mounted at the exhaust port. This duct 10 is used to discharge heat generated by the mobile air conditioner body outdoors along with the second fan 9. The duct is retractable, but its maximum length cannot exceed 170 cm. A displacement sensor 13 is mounted above the duct 10 to detect the extended length of the duct 10 in real time.

[0067] The controller is configured to, when the mobile air conditioner 100 is in horizontal air supply mode (where the unit moves left and right), detect the displacement sensor value and save it in RealLengthBACKUP1. It then controls the mobile air conditioner 100 to move rightward (four rollers are located at the bottom of the unit, driven by a motor. The motorized rollers can move in four directions, namely, forward, backward, left, and right). The controller also obtains the RealLength value detected by the displacement sensor 13 in real time. If the RealLength value reaches the maximum extension length (LengthMAX) of the displacement sensor 13, indicating that the current displacement distance has reached the maximum extension length of the exhaust duct, the mobile air conditioner 100 is controlled to stop moving rightward and begin moving leftward. This is repeated until the RealLength value reaches LengthMAX, indicating that the current displacement distance has reached the maximum extension length of the exhaust duct. The mobile air conditioner 100 is then controlled to stop moving leftward. When the mobile air conditioner 100 is in longitudinal air supply mode (where the unit moves forward and backward), the controller controls the mobile air conditioner 100 to move forward and obtains the RealLength value detected by the displacement sensor 13 in real time. If the detection value RealLength reaches the maximum stretching length LengthMAX, it means that the current displacement distance has reached the maximum stretching distance of the exhaust duct, and the mobile air conditioner 100 is controlled to stop moving forward and start moving backward until the detection value RealLength reaches the initial minimum distance RealLengthBACKUP2 of the displacement sensor 13, which means that the current displacement distance has reached the initial minimum distance of the exhaust duct, and the mobile air conditioner 100 is controlled to stop moving backward.

[0068] It should be noted that this embodiment of the present invention drives the entire device to move horizontally or vertically. When moving horizontally or horizontally, the horizontal wind mode is set as the starting point, and then the horizontal movement is carried out. Therefore, only the RealLength and LengthMAX values ​​need to be determined. When moving vertically, the longitudinal wind mode is also set as the starting point, and then the forward and backward movement is carried out. However, the difference is that when moving forward, the RealLength and LengthMAX values ​​are determined, while when moving backward, RealLengthBACKUP2 is used as the minimum value for backward movement, so RealLength and RealLengthBACKUP2 are used for logical judgment.

[0069] 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, thereby increasing the air supply distance and air supply angle of the mobile air conditioner and effectively improving the user experience.

[0070] As one of the optional embodiments, the displacement sensor 13 is a pull-wire displacement sensor, one end of which is installed at one end of the exhaust duct 10, and the other end of which is installed at the other end of the exhaust duct 10 through a hook.

[0071] For details, please refer to Figure 7 In the embodiment of the present invention, the displacement sensor is a pull-wire displacement sensor, 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. 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 pull-wire 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.

[0072] As one of the optional embodiments, the controller is further configured to:

[0073] When the mobile air conditioner 100 is in the horizontal air supply mode or the vertical air supply mode, determining whether the detection value of the displacement sensor 13 is greater than zero;

[0074] If yes, it is determined that the displacement sensor 13 is installed in place;

[0075] If not, it is determined that the displacement sensor 13 is not installed in place or the exhaust tube 10 is not installed.

[0076] Specifically, when the mobile air conditioner is in horizontal or vertical air supply mode, the embodiment of the present invention determines whether the displacement sensor's detection value, RealLength, is greater than zero. If so, the hook of the pull cord displacement sensor is determined to be attached to the end of the fan, indicating that the displacement sensor is properly installed. If not, the displacement sensor is determined to be inadequately installed or the exhaust fan is not installed. The display panel digital tube displays "EE," indicating that the exhaust fan is not installed (not secured), and the entire unit stops moving.

[0077] As one of the optional embodiments, the controller is further configured to:

[0078] After controlling the mobile air conditioner 100 to move rightward, determining whether the first timer is equal to zero;

[0079] If so, the first timer is controlled to start timing. When the first timer reaches the first preset time, it is determined whether the initial value of the displacement sensor 13 is equal to the detection value; if it is equal, it is determined that the displacement sensor 13 is not installed in place or the exhaust duct 10 is not installed; if not, it is determined that the displacement sensor 13 is installed in place;

[0080] If not, there is no need to determine again whether the displacement sensor 13 is installed in place.

[0081] For details, please refer to Figure 8 , Figure 8 This is a first working flow diagram of a controller in a mobile air conditioner provided by an embodiment of the present invention. After controlling the mobile air conditioner to move to the right, the embodiment of the present invention first determines whether the first timer TIMER1 is equal to zero. If the first timer TIMER1 is equal to zero, it means that the logic is executed for the first time, and a hook position judgment is required. The first timer TIMER1 is controlled to start timing. When the first timer TIMER1 times to the first preset time, for example, 2s, it is determined whether the initial value RealLengthBACKUP1 of the displacement sensor is equal to the detection value RealLength; if RealLengthBACKUP1 is equal to the detection value RealLength, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed; if RealLengthBACKUP1 is not equal to the detection value RealLength, it is determined that the displacement sensor is installed in place. If the first timer TIMER1 is not equal to zero, it means that the hook position judgment has been made before, and there is no need to determine again whether the displacement sensor is installed in place.

[0082] As one of the optional embodiments, the controller is further configured to:

[0083] After controlling the mobile air conditioner 100 to move forward, determining whether the second timer is equal to zero;

[0084] If so, the second timer is controlled to start timing. When the second timer reaches the second preset time, it is determined whether the initial value of the displacement sensor 13 is equal to the detection value; if it is equal, it is determined that the displacement sensor 13 is not installed in place or the exhaust duct 10 is not installed; if not, it is determined that the displacement sensor 13 is installed in place;

[0085] If not, there is no need to determine again whether the displacement sensor 13 is installed in place.

[0086] For details, please refer to Figure 9 , Figure 9This is a second working flow diagram of a controller in a mobile air conditioner provided by an embodiment of the present invention. After controlling the mobile air conditioner to move forward, the embodiment of the present invention first determines whether the second timer TIMER2 is equal to zero. If the second timer TIMER2 is equal to zero, it means that the logic is executed for the first time, and a hook position judgment is required. The second timer TIMER2 is controlled to start timing. When the second timer TIMER2 times to the second preset time, for example, 2s, it is determined whether the initial value RealLengthBACKUP2 of the displacement sensor is equal to the detection value RealLength; if RealLengthBACKUP2 is equal to the detection value RealLength, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed; if RealLengthBACKUP2 is not equal to the detection value RealLength, it is determined that the displacement sensor is installed in place. If the second timer TIMER2 is not equal to zero, it means that the hook position judgment has been made before, and there is no need to determine again whether the displacement sensor is installed in place.

[0087] It should be noted that the embodiment of the present invention performs two hook position judgments. The first is to determine whether the hook is stretched and hung in a fixed position, and the second is to determine whether the telescopic length can be detected normally after the hook is hung in a fixed position. The two judgment purposes are different. The first time is when the horizontal or vertical wind mode is set to judge whether the RealLength is greater than 0. If it is equal to 0, it means that the hook is not placed in the specified position or is not connected to the exhaust duct, which ultimately causes the subsequent logic to be unable to judge. The second time is when the horizontal or vertical mode is set, first let the whole machine move for a period of time. The time is set to 2s. After the end of 2s, compare the rope displacement sensor values ​​2s before and 2s after to see if they are equal. If they are equal, it means that the hook is not hung in the correct position, resulting in the rope sensor being unable to detect the telescopic length, or the rope sensor body is faulty and causes the length to be detected. If they are not equal, it means that the rope sensor can detect the telescopic length normally after a 2s delay.

[0088] See also Figure 10 , Figure 10 The figure is a flow chart of a mobile air conditioner intelligent air supply control method provided by one embodiment of the present invention. The mobile air conditioner intelligent air supply control method provided by the embodiment of the present invention is applied to a mobile air conditioner including a housing, an indoor unit, an outdoor unit, an exhaust duct, and a displacement sensor. The exhaust duct is detachably mounted at the exhaust port. The displacement sensor is mounted on the exhaust duct and is used to detect the extension and retraction length of the exhaust duct. The mobile air conditioner intelligent air supply control method includes:

[0089] S1, when the mobile air conditioner is in a horizontal air supply mode, controlling the mobile air conditioner to move rightward and acquiring a detection value of the displacement sensor in real time; if the detection value reaches a maximum stretching length of the displacement sensor, controlling the mobile air conditioner to stop moving rightward and start moving leftward, until the detection value reaches the maximum stretching length, at which point controlling the mobile air conditioner to stop moving leftward;

[0090] S2, when the mobile air conditioner is in the longitudinal air supply mode, control the mobile air conditioner to move forward and obtain the detection value of the displacement sensor in real time; if the detection value reaches the maximum stretching length, control the mobile air conditioner to stop moving forward and start moving backward until the detection value reaches the initial minimum distance of the displacement sensor, and control the mobile air conditioner to stop moving backward.

[0091] Specifically, in this embodiment of the present invention, when the mobile air conditioner is in horizontal air supply mode (the body moves left and right), the displacement sensor value is detected and saved in RealLengthBACKUP1. The mobile air conditioner is controlled to move rightward (four rollers are placed at the bottom of the body, and the rollers can be driven by a motor to move in four directions, namely front, back, left, and right). The displacement sensor detection value RealLength is obtained in real time. If the detection value RealLength reaches the maximum stretch length LengthMAX of the displacement sensor, it indicates that the current displacement distance has reached the maximum stretch distance of the exhaust duct. The mobile air conditioner is controlled to stop moving rightward and begin moving leftward until the detection value RealLength reaches the maximum stretch length LengthMAX. This indicates that the current displacement distance has reached the maximum stretch distance of the exhaust duct. The mobile air conditioner is controlled to stop moving leftward. When the mobile air conditioner is in longitudinal air supply mode (the body moves forward and backward), the mobile air conditioner is controlled to move forward, and the displacement sensor detection value RealLength is obtained in real time. If the detection value RealLength reaches the maximum stretching length LengthMAX, it means that the current displacement distance has reached the maximum stretching distance of the exhaust duct, and the mobile air conditioner is controlled to stop moving forward and start moving backward until the detection value RealLength reaches the initial minimum distance RealLengthBACKUP2 of the displacement sensor, which means that the current displacement distance has reached the initial minimum distance of the exhaust duct, and the mobile air conditioner is controlled to stop moving backward.

[0092] It should be noted that this embodiment of the present invention drives the entire device to move horizontally or vertically. When moving horizontally or horizontally, the horizontal wind mode is set as the starting point, and then the horizontal movement is carried out. Therefore, only the RealLength and LengthMAX values ​​need to be determined. When moving vertically, the longitudinal wind mode is also set as the starting point, and then the forward and backward movement is carried out. However, the difference is that when moving forward, the RealLength and LengthMAX values ​​are determined, while when moving backward, RealLengthBACKUP2 is used as the minimum value for backward movement, so RealLength and RealLengthBACKUP2 are used for logical judgment.

[0093] 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, thereby increasing the air supply distance and air supply angle of the mobile air conditioner and effectively improving the user experience.

[0094] As one of the optional embodiments, the displacement sensor is a pull-wire displacement sensor, 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.

[0095] Specifically, the displacement sensor in the embodiment of the present invention is a pull-wire displacement sensor, 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 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 pull-wire 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.

[0096] As an optional embodiment, the method further includes:

[0097] When the mobile air conditioner is in a horizontal air supply mode or a vertical air supply mode, determining whether a detection value of the displacement sensor is greater than zero;

[0098] If so, it is determined that the displacement sensor is installed in place;

[0099] If not, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed.

[0100] Specifically, when the mobile air conditioner is in horizontal or vertical air supply mode, the embodiment of the present invention determines whether the displacement sensor's detection value, RealLength, is greater than zero. If so, the hook of the pull cord displacement sensor is determined to be attached to the end of the fan, indicating that the displacement sensor is properly installed. If not, the displacement sensor is determined to be inadequately installed or the exhaust fan is not installed. The display panel digital tube displays "EE," indicating that the exhaust fan is not installed (not secured), and the entire unit stops moving.

[0101] As an optional embodiment, the method further includes:

[0102] After controlling the mobile air conditioner to move rightward, determining whether the first timer is equal to zero;

[0103] If so, the first timer is controlled to start timing, and when the first timer reaches a first preset time, it is determined whether the initial value of the displacement sensor is equal to the detection value; if it is equal, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed; if it is not equal, it is determined that the displacement sensor is installed in place;

[0104] If not, there is no need to determine again whether the displacement sensor is installed in place.

[0105] Specifically, after controlling the mobile air conditioner to move to the right, the embodiment of the present invention first determines whether the first timer TIMER1 is equal to zero. If the first timer TIMER1 is equal to zero, it indicates that this logic is being executed for the first time and a hook position determination is required. The first timer TIMER1 is controlled to start timing. When the first timer TIMER1 reaches a first preset time, such as 2 seconds, it is determined whether the initial value RealLengthBACKUP1 of the displacement sensor is equal to the detection value RealLength. If RealLengthBACKUP1 is equal to the detection value RealLength, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed. If RealLengthBACKUP1 is not equal to the detection value RealLength, it is determined that the displacement sensor is installed in place. If the first timer TIMER1 is not equal to zero, it indicates that the hook position determination has been made previously and there is no need to determine whether the displacement sensor is installed in place again.

[0106] As an optional embodiment, the method further includes:

[0107] After controlling the mobile air conditioner to move forward, determining whether the second timer is equal to zero;

[0108] If so, the second timer is controlled to start timing, and when the second timer reaches a second preset time, it is determined whether the initial value of the displacement sensor is equal to the detection value; if it is equal, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed; if it is not equal, it is determined that the displacement sensor is installed in place;

[0109] If not, there is no need to determine again whether the displacement sensor is installed in place.

[0110] Specifically, after controlling the mobile air conditioner to move forward, the embodiment of the present invention first determines whether the second timer TIMER2 is equal to zero. If the second timer TIMER2 is equal to zero, it indicates that this logic is being executed for the first time and a hook position determination is required. The second timer TIMER2 is controlled to start timing. When the second timer TIMER2 reaches a second preset time, such as 2 seconds, it is determined whether the initial value RealLengthBACKUP2 of the displacement sensor is equal to the detection value RealLength. If RealLengthBACKUP2 is equal to the detection value RealLength, it is determined that the displacement sensor is not installed in place or the exhaust duct is not installed. If RealLengthBACKUP2 is not equal to the detection value RealLength, it is determined that the displacement sensor is installed in place. If the second timer TIMER2 is not equal to zero, it indicates that the hook position determination has been made previously and there is no need to determine whether the displacement sensor is installed in place again.

[0111] It should be noted that the embodiment of the present invention performs two hook position judgments. The first is to determine whether the hook is stretched and hung in a fixed position, and the second is to determine whether the telescopic length can be detected normally after the hook is hung in a fixed position. The two judgment purposes are different. The first time is when the horizontal or vertical wind mode is set to judge whether the RealLength is greater than 0. If it is equal to 0, it means that the hook is not placed in the specified position or is not connected to the exhaust duct, which ultimately causes the subsequent logic to be unable to judge. The second time is when the horizontal or vertical mode is set, first let the whole machine move for a period of time. The time is set to 2s. After the end of 2s, compare the rope displacement sensor values ​​2s before and 2s after to see if they are equal. If they are equal, it means that the hook is not hung in the correct position, resulting in the rope sensor being unable to detect the telescopic length, or the rope sensor body is faulty and causes the length to be detected. If they are not equal, it means that the rope sensor can detect the telescopic length normally after a 2s delay.

[0112] An embodiment of the present invention provides a mobile air conditioner and an intelligent air supply control method thereof. A displacement sensor is installed on the exhaust duct to detect the exhaust duct's telescopic length in real time. When the mobile air conditioner is in horizontal air supply mode, the mobile air conditioner is controlled to move rightward and the displacement sensor's detection value is acquired in real time. If the detection value reaches the displacement sensor's maximum telescopic length, the mobile air conditioner is controlled to stop moving rightward and begin moving leftward until the detection value reaches the maximum telescopic length, at which point the mobile air conditioner is controlled to stop moving leftward. When the mobile air conditioner is in longitudinal air supply mode, the mobile air conditioner is controlled to move forward and the displacement sensor's detection value is acquired in real time. If the detection value reaches the maximum telescopic length, the mobile air conditioner is controlled to stop moving forward and begin moving backward until the detection value reaches the displacement sensor's initial minimum distance, at which point the mobile air conditioner is controlled to stop moving backward. This embodiment of the present invention, by real-time detection of the exhaust duct's telescopic length, controls the movable trajectory of the entire unit, increases the air supply distance and angle of the mobile air conditioner, and effectively improves the user experience.
