For example, the vehicle-mounted top-mounted air conditioner of the present application can be applied to cars, off-road vehicles, buses or trucks, etc.

[0029] In addition, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. Those skilled in the art can understand the specific meaning of the above-mentioned term in the present application according to the specific circumstances.

[0030] In order to solve the problem that the existing roof-mounted air conditioner is prone to rain and snow entering from the top air outlet and affecting the operation stability during use, the application provides a roof-mounted air conditioner and a control method thereof, which can reduce the rain and snow entering from the top air outlet and ensure the operation stability of the roof-mounted air conditioner.

[0031] The control method of the roof-mounted air conditioner will be introduced below. Figures 1 to 4 Figure 1 is the main step diagram of the control method of the roof-mounted air conditioner of the application; Figure 2 is the specific step diagram of the control method of the roof-mounted air conditioner of the first embodiment of the application; Figure 3 is the specific step diagram of the control method of the roof-mounted air conditioner of the second embodiment of the application; Figure 4 is the specific step diagram of the control method of the roof-mounted air conditioner of the third embodiment of the application.

[0032] The roof-mounted air conditioner of the application is installed on a vehicle, and the top of the roof-mounted air conditioner is provided with an air outlet, the air outlet is provided with a cover plate that opens and closes in a lifting manner, the cover plate is closed at the air outlet and closes the air outlet when it is at the lowest position, and the roof-mounted air conditioner is arranged to obtain precipitation information of the current position. Specifically, the roof-mounted air conditioner is an Internet of Things air conditioner, the controller thereof is in communication connection with the Internet and the vehicle infotainment system, so as to obtain the current position of the vehicle by means of the positioning device on the vehicle, and then obtain the precipitation information of the current position from the Internet, and the controller of the roof-mounted air conditioner is also in communication connection with the motor that drives the cover plate to rotate.

[0033] As shown in Figure 1 , the control method of the roof-mounted air conditioner mainly includes the following steps:

[0034] Step S100, during the process that the vehicle is stationary and the roof-mounted air conditioner is running, obtaining the precipitation information of the current position.

[0035] When the roof-mounted air conditioner is running, the controller of the roof-mounted air conditioner obtains the position of the vehicle from the vehicle infotainment system, and judges whether the vehicle is in a stationary state according to whether the position of the vehicle changes, when the vehicle is in a stationary state, the controller of the roof-mounted air conditioner obtains the precipitation information of the current position from the Internet (i.e. obtains the precipitation information of the current position through weather forecast).

[0036] Step S200, judging whether the current position is in a precipitation state, if yes, executing step S300, and if not, executing step S400.

[0037] Step S300, raising the cover plate to a position between the lowest position and the highest position.​

[0038] Step S400, the cover plate is raised to the highest position.

[0039] By such a control method, the cover plate can be positioned between the lowest position and the highest position in rainy and snowy weather, the distance between the air outlet and the cover plate is reduced on the basis of the air outlet being communicated with the external environment, the probability of rain and snow entering the air outlet at the peripheral position between the air outlet and the cover plate is reduced, the rain and snow entering the air outlet is reduced, thereby reducing the influence on the heat exchange performance of the heat exchanger and ensuring the operation stability of the vehicle-mounted top-mounted air conditioner.

[0040] It should be noted that in the state that the vehicle-mounted top-mounted air conditioner is not working, the cover plate is positioned at the lowest position to close the air outlet, which can also reduce the dust entering from the air outlet and falling on the heat exchanger of the external unit part, and avoid the heat exchanger surface from accumulating a large amount of dust to affect the heat exchange performance.

[0041] In the first embodiment of the present application, four linear motors are arranged at the four corners of the air outlet respectively, the telescopic shafts of the linear motors are vertically arranged, and the upper ends of the telescopic shafts of the four linear motors are connected with the four corners of the cover plate respectively. The controller of the vehicle-mounted top-mounted air conditioner is in communication connection with the four linear motors. As shown in the figure, Figure 2 The control method of the vehicle-mounted top-mounted air conditioner includes the following steps:

[0042] Step S100, in the process that the vehicle is stationary and the vehicle-mounted top-mounted air conditioner is running, the precipitation information of the current position is acquired.

[0043] Step S200, it is judged whether the current position is in the precipitation state, if yes, step S311 is executed, if not, step S400 is executed.

[0044] Step S311, the target position of the cover plate is determined according to the precipitation intensity. The height of the target position is negatively related to the precipitation intensity.

[0045] That is, the greater the precipitation intensity, the smaller the height of the target position of the cover plate.

[0046] Step S312, the cover plate is raised to the target position.

[0047] The controller of the vehicle-mounted top-mounted air conditioner controls the telescopic shafts of the four linear motors to be elongated to the length corresponding to the target position, so that the cover plate reaches the target position.

[0048] Step S400, the cover plate is raised to the highest position.

[0049] The controller of the vehicle-mounted top-mounted air conditioner controls the telescopic shafts of the four linear motors to be elongated to the length corresponding to the highest position, so that the cover plate reaches the highest position.

[0050] Through the arrangement, the rain and snow can be reduced from entering the air outlet, and the influence of the cover plate on the air volume can be reduced as much as possible, so that the heat exchange performance of the heat exchanger of the external machine part of the vehicle-mounted top-mounted air conditioner is ensured.

[0051] It should be noted that the four linear motors are arranged at the four corners of the air outlet, the telescopic shafts of the linear motors are arranged vertically, and the upper ends of the telescopic shafts of the four linear motors are connected with the four corners of the cover plate. This is only one specific arrangement, and in actual application, it can be adjusted, such as in one feasible arrangement, one linear motor is arranged at one side of the air outlet, and the upper end of the telescopic shaft of the linear motor is connected with the corresponding position of the cover plate. In another feasible arrangement, a vertically sliding rack is arranged at the position where the vehicle-mounted top-mounted air conditioner is located near the air outlet, a rotary motor is arranged on the vehicle-mounted top-mounted air conditioner, a gear is arranged on the output shaft of the rotary motor, the gear is engaged with the rack, and the rotary motor drives the gear and the rack to realize the lifting movement of the cover plate.

[0052] In the second embodiment of the present application, as shown in Figure 3 The control method of the vehicle-mounted top-mounted air conditioner comprises the following steps:

[0053] In step S100, the precipitation information of the current position is obtained during the driving of the vehicle and the operation of the vehicle-mounted top-mounted air conditioner.

[0054] In step S200, it is judged whether the current position is in the precipitation state, if yes, step S321 is executed, and if not, step S400 is executed.

[0055] In step S321, the wind speed of the current position is obtained.

[0056] For example, the controller of the vehicle-mounted top-mounted air conditioner can obtain the current position of the vehicle by means of the positioning device on the vehicle, and then obtain the wind speed of the current position from the Internet (i.e. the wind speed of the current position is obtained by the wind speed level in the weather forecast).

[0057] In step S322, the target position of the cover plate is determined according to the wind speed and the precipitation intensity. The height of the target position is negatively related to the precipitation intensity, and the height of the target position is also negatively related to the wind speed.

[0058] That is, the greater the precipitation intensity, the smaller the height of the target position of the cover plate, and the greater the wind speed, the smaller the height of the target position of the cover plate.

[0059] In step S323, the cover plate is lifted to the target position.

[0060] In step S400, the cover plate is lifted to the highest position.

[0061] The greater the wind speed, the more likely it is for rain and snow to enter the air outlet at the top of the roof-mounted air conditioner. By matching the height of the target position of the cover plate to the speed of the vehicle, the amount of rain and snow entering the air outlet is reduced, and the impact of the cover plate on the air flow from the air outlet is minimized.

[0062] In a third embodiment of the present application, as shown in Figure 4 the control method of the roof-mounted air conditioner comprises the following steps:

[0063] In step S100, during the process of the vehicle being stationary and the roof-mounted air conditioner operating, obtain the precipitation information of the current position.

[0064] In step S200, determine whether the current position is in a precipitation state. If yes, execute step S331, and if no, execute step S400.

[0065] In step S331, obtain the wind speed of the current position.

[0066] In step S332, determine the target position of the cover plate according to the wind speed and the precipitation intensity. The height of the target position is negatively correlated with the precipitation intensity, and the height of the target position is also negatively correlated with the wind speed.

[0067] In step S333, raise the cover plate to the target position and increase the rotation speed of the outer fan.

[0068] In step S400, raise the cover plate to the highest position.

[0069] In rainy and snowy weather conditions, when the cover plate is raised to a position between the lowest position and the highest position, the resistance of the cover plate to the air flow from the air outlet is greater than when the cover plate is in the highest position, which has a certain impact on the air flow. By increasing the rotation speed of the outer fan when the cover plate is raised to a position between the lowest position and the highest position, the air flow can be improved, thereby eliminating the impact of the reduced air flow on the heat exchange performance of the heat exchanger.

[0070] Preferably, in step S333, the "increasing the rotation speed of the outer fan" specifically comprises: increasing the rotation speed of the outer fan according to the target position. The increase in the rotation speed of the outer fan is negatively correlated with the height of the target position. In this way, when the height of the target position of the cover plate is different, the rotation speed of the outer fan is increased by a corresponding rotation speed, which can more effectively ensure the stability of the air flow, thereby ensuring the heat exchange performance of the heat exchanger and improving the operating stability of the roof-mounted air conditioner.

[0071] On the basis of each of the above embodiments, preferably, the step of determining the target position of the cover plate comprises: obtaining the outdoor environment temperature during the heating operation of the vehicle-mounted top-mounted air conditioner; and determining the target position of the cover plate according to the outdoor environment temperature and corresponding parameters (precipitation intensity and / or wind speed). In the case of the same precipitation intensity and wind speed, the height of the target position determined when the outdoor environment temperature is greater than a preset temperature is greater than the height of the target position determined when the outdoor environment temperature is not greater than the preset temperature, wherein the preset temperature is 0-5℃. Since the outdoor environment temperature is low during the heating operation of the vehicle-mounted top-mounted air conditioner, if rain or snow enters the air inlet at the top of the vehicle-mounted top-mounted air conditioner, it is easy to freeze, and the influence on the heat exchange performance of the heat exchanger is greater. Through such a setting, during the heating operation of the vehicle-mounted top-mounted air conditioner, the risk of rain or snow entering the air outlet is further reduced, and the operation stability of the vehicle-mounted top-mounted air conditioner is ensured.

[0072] On the basis of each of the above embodiments, preferably, the vehicle-mounted top-mounted air conditioner is further configured to obtain the wind direction of the current location, and the cover plate is further configured to be able to tilt in different directions. In addition to the step of raising the cover plate to a position between the lowest position and the highest position, the control method further comprises: making the cover plate be in a tilted state and the top surface of the cover plate be in a windward state. The controller of the vehicle-mounted top-mounted air conditioner obtains the wind direction of the current location from the Internet (i.e., obtains the wind direction of the current location through weather forecast information).

[0073] For example, four linear motors are arranged at the four corners of the air outlet, the extension shafts of the linear motors are vertically arranged, and the upper ends of the extension shafts of the four linear motors are connected to the four corners of the cover plate through ball joint hinges. The controller of the vehicle-mounted top-mounted air conditioner is in communication connection with the four linear motors. By controlling the extension shafts of the four linear motors to extend by the same length, the cover plate is raised to a position corresponding to the height, by controlling the extension shafts of two adjacent linear motors in the four linear motors to extend by a first length and controlling the extension shafts of the other two linear motors to extend by a second length, the cover plate can be in a tilted state, or the extension shafts of the four linear motors can all extend by different lengths to make the cover plate be in a tilted state. The direction in which the cover plate tilts is determined according to the wind direction of the current location, so that the top surface of the cover plate is in a windward state. Through such a setting, rain or snow can be more effectively blocked from entering the air outlet.

[0074] It should be noted that one linear motor can also be arranged on one side of the air outlet, the upper end of the extension shaft of the linear motor is fixedly connected to a first rotary motor, the output shaft of the first rotary motor is fixedly connected to a second rotary motor, and the output shaft of the second rotary motor is fixedly connected to the cover plate. The tilting direction of the cover plate is adjusted through the cooperative action of the first rotary motor and the second rotary motor.

[0075] In the above various embodiments, the controller of the vehicle-mounted top air conditioner is communicatively connected with the infotainment system of the vehicle to obtain the current location, which is only a specific setting mode, and in actual application, adjustment can be made thereto, for example, the controller of the vehicle-mounted top air conditioner can also be communicatively connected with a smart terminal (such as a smart phone, a smart watch or a smart bracelet, etc.), and the current location is obtained by means of a positioning device on the smart terminal. In addition, the vehicle-mounted top air conditioner can also not be an Internet of Things air conditioner, and a rain and snow sensor and a wind speed and direction detection device are arranged on the vehicle-mounted top air conditioner to obtain the precipitation information of the current location by means of the rain and snow sensor and to obtain the wind speed and direction by means of the wind speed and direction detection device. The rain and snow sensor and the wind speed and direction detection device are existing devices, and thus will not be described here.

[0076] In another aspect, the present application also provides a vehicle-mounted top air conditioner, which comprises a memory, a processor and a computer program, the computer program is stored in the memory and is configured to be executed by the processor to realize the control method of the vehicle-mounted top air conditioner in any one of the above embodiments.

[0077] It should be noted that the memory in the above embodiments includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register, etc., and the processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor, etc. In addition, the vehicle-mounted top air conditioner can be applied to a sedan, a cross-country vehicle, a passenger car or a truck, etc.

[0078] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will all fall within the protection scope of the present application.
