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 recycling 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 motor. Each model has a maximum air delivery distance—the maximum distance a person standing directly in front of the unit 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. To maximize cooling efficiency, the lower fan unit is connected to an exhaust duct, securing it to the outside to dissipate heat. While mobile air conditioners are inherently mobile, moving them to a distant location during operation can cause the exhaust duct to become stretched, making movement difficult. To return the unit to its original position, the user must manually push it back to the designated location. Summary of the Invention

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:

[0062] 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.

[0063] 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;

[0064] 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;

[0065] An exhaust tube 10, wherein the exhaust tube 10 is detachably mounted at the exhaust port;

[0066] A first displacement sensor 13, which is installed on the left side of the exhaust cylinder 10;

[0067] A second displacement sensor 14, which is installed on the right side of the exhaust cylinder 10;

[0068] The controller is configured to, when the first detection value of the first displacement sensor 13 reaches the first initial value of the first displacement sensor 13 and the second detection value of the second displacement sensor 14 reaches the second initial value of the second displacement sensor 14, determine the size relationship between the first detection value and the second detection value; calculate the moving distance of the mobile air conditioner 100 according to the determination result, and control the mobile air conditioner 100 to move to the initial position according to the moving distance.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] The controller is configured to set the entire machine to recovery mode, and when the first detection value RealLengthLeft of the first displacement sensor 13 reaches the first initial value LengthLeft of the first displacement sensor 13, and the second detection value RealLengthRight of the second displacement sensor 14 reaches the second initial value LengthRight of the second displacement sensor 14, judge the size relationship between the first detection value RealLengthLeft and the second detection value RealLengthRight; calculate the moving distance of the mobile air conditioner 100 according to the judgment result, and control the mobile air conditioner 100 to move to the initial position according to the moving distance.

[0075] It should be noted that in this embodiment of the present invention, the initial position of the displacement sensor is preset in EEPROM, along with the preset LengthLeft and LengthRight values. These preset values ​​represent the left and right displacement sensor lengths when the exhaust duct is naturally unextended and placed horizontally. When the unit is powered on, the RealLengthLeft and RealLengthRight values ​​are measured in real time, and subsequent movement distances are calculated based on the comparison of these values.

[0076] The embodiment of the present invention detects the stretched length of the exhaust duct in real time and calculates the movable distance of the whole machine without increasing the cost, so that the whole machine automatically moves to the initial position, thereby effectively improving the user experience.

[0077] 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.

[0078] 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.

[0079] As one of the optional embodiments, the controller is further configured to:

[0080] determining whether the first detection value of the first displacement sensor 13 reaches the first initial value of the first displacement sensor 13;

[0081] 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 whether the second detection value of the second displacement sensor 14 reaches the second initial value of the second displacement sensor 14 is further determined;

[0082] 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.

[0083] Specifically, in an embodiment of the present invention, when the mobile air conditioner is in recovery mode, it is determined whether the first detection value RealLengthLeft of the first displacement sensor reaches the first initial value LengthLeft of the first displacement sensor. 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 RealLengthRight of the second displacement sensor reaches the second initial value LengthRight of the second displacement sensor. 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.

[0084] As one of the optional embodiments, the calculating the moving distance of the mobile air conditioner 100 according to the judgment result, and controlling the mobile air conditioner 100 to move to the initial position according to the moving distance specifically includes:

[0085] If the first detection value is greater than the second detection value, the left roller at the bottom of the mobile air conditioner 100 is controlled to move backward until the first detection value is equal to the second detection value, and the left and right rollers at the bottom of the mobile air conditioner 100 are controlled to move backward simultaneously;

The first moving distance of the mobile air conditioner is calculated based on the first detection value RealLengthLeft and the first initial value LengthLeft, and the second moving distance of the mobile air conditioner is calculated based on the second detection value RealLengthRight and the second initial value LengthRight; the mobile air conditioner is controlled to move to the initial position based on the first moving distance and the second moving distance.

In the embodiment of the present invention, if the first detection value RealLengthLeft is equal to the second detection value RealLengthRight, it means that the machine is already in a horizontal state.

The mobile air conditioner intelligent recycling control method includes:

[0100] S1, when a first detection value of the first displacement sensor reaches a first initial value of the first displacement sensor, and a second detection value of the second displacement sensor reaches a second initial value of the second displacement sensor, determining a magnitude relationship between the first detection value and the second detection value;

[0101] S2, calculating a moving distance of the mobile air conditioner according to the determination result, and controlling the mobile air conditioner to move to an initial position according to the moving distance.

[0102] Specifically, in the embodiment of the present invention, the entire machine is set to recovery mode. When the first detection value RealLengthLeft of the first displacement sensor reaches the first initial value LengthLeft of the first displacement sensor, and the second detection value RealLengthRight of the second displacement sensor reaches the second initial value LengthRight of the second displacement sensor, the size relationship between the first detection value RealLengthLeft and the second detection value RealLengthRight is judged; the moving distance of the mobile air conditioner is calculated based on the judgment result, and the mobile air conditioner is controlled to move to the initial position based on the moving distance.

[0103] It should be noted that in this embodiment of the present invention, the initial position of the displacement sensor is preset in EEPROM, along with the preset LengthLeft and LengthRight values. These preset values ​​represent the left and right displacement sensor lengths when the exhaust duct is naturally unextended and placed horizontally. When the unit is powered on, the RealLengthLeft and RealLengthRight values ​​are measured in real time, and subsequent movement distances are calculated based on the comparison of these values.

[0104] The embodiment of the present invention detects the stretched length of the exhaust duct in real time and calculates the movable distance of the whole machine without increasing the cost, so that the whole machine automatically moves to the initial position, thereby effectively improving the user experience.

[0105] 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.

[0106] 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.

[0107] As an optional embodiment, the method further includes:

[0110] 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.

[0111] Specifically, in an embodiment of the present invention, when the mobile air conditioner is in recovery mode, it is determined whether the first detection value RealLengthLeft of the first displacement sensor reaches the first initial value LengthLeft of the first displacement sensor. 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 RealLengthRight of the second displacement sensor reaches the second initial value LengthRight of the second displacement sensor. 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.
