Description

Technical Field

[0001] The present application belongs to the technical field of air conditioners, and in particular relates to a mobile air conditioner. Background Art

[0002] When using a mobile air conditioner, an exhaust duct is usually required to discharge the heat generated by the mobile air conditioner body to the outside. In certain usage environments, the mobile air conditioner may not be connected to an exhaust duct. In this case, the heat generated by the lower air outlet of the mobile air conditioner cannot be discharged to the outdoor space through the exhaust duct, but is blown back to the inside of the body with air circulation or encountering obstacles, thereby affecting the ambient temperature sampling inside the body, causing a difference between the sampled temperature and the actual indoor temperature, which seriously affects the operation of the body.

[0003] In the prior art, the indoor ambient temperature and outdoor temperature of the mobile air conditioner are detected, and corresponding control is performed on the mobile air conditioner according to the temperature difference between the ambient temperature and the indoor temperature. However, for the use without connecting the exhaust duct, the control effect is not high, and even affects the operating safety of the mobile air conditioner. Summary of the invention

[0007] An indoor unit, the indoor unit comprising a first heat exchanger and a first fan, the first heat exchanger and the first fan being arranged in the indoor side air duct, the first fan driving indoor air from the first air inlet into the indoor side air duct to exchange heat with the first heat exchanger, and then being discharged from the air outlet;

[0008] An outdoor unit, the outdoor unit comprising a compressor, a second heat exchanger and a second fan, the compressor, the second heat exchanger and the second fan are arranged in the outdoor air duct, the second fan drives the airflow from the second air inlet into the outdoor air duct to exchange heat with the second heat exchanger, and then is discharged from the air outlet;

[0009] An exhaust pipe, the exhaust pipe is detachably mounted at the exhaust port;

[0010] A controller, the controller being configured to:

[0011] When the mobile air conditioner operates in a cooling mode and the compressor is turned on, obtaining a first temperature at the second air inlet;

[0012] When the compressor runs for a first start time, obtaining a second temperature at the second air inlet;

[0013] determining whether the mobile air conditioner is equipped with an exhaust duct according to the relationship between the first temperature and the second temperature;

[0014] If it is determined that the mobile air conditioner is not equipped with the exhaust duct, the distance between the mobile air conditioner and the obstacle is obtained, and the operating state of the mobile air conditioner is controlled according to the distance.

[0015] In the present application, a controller is set in the mobile air conditioner, and the temperature at the second air inlet of the mobile air conditioner is detected multiple times by the controller. According to the temperature between two detections, it is judged whether the mobile air conditioner is installed with an exhaust duct. When it is determined that the mobile air conditioner is not installed with an exhaust duct, the distance between the mobile air conditioner and the obstacle is obtained by the distance detection component. When the distance is less than the upper limit value of the distance, it indicates that the current use of the mobile air conditioner may cause damage to the body itself. Therefore, the operating time of the compressor and the temperature of the condenser are obtained, and different control logics are set according to the operating time of the compressor and the temperature of the condenser to change the operating state of the mobile air conditioner, so as to ensure that the mobile air conditioner has a better heat dissipation effect when operating in the cooling mode and without installing an exhaust duct, thereby ensuring the operating safety of the mobile air conditioner to a certain extent.

[0029] It should be noted that a mobile air conditioner refers to an air conditioner that integrates the indoor and outdoor units of an ordinary air conditioner. It does not have an outdoor unit. It uses the cooling of the compressor and the exhaust duct to discharge the hot air. It can be placed anywhere in the room to achieve the effect of cooling down a local area.

[0030] The characteristic of mobile air conditioners is that they can be moved at will. Users can adjust the indoor position of the mobile air conditioner according to their needs. When using the mobile air conditioner for cooling, an external exhaust duct is usually required. The function of the exhaust duct is to discharge the heat from the air outlet to the outside. When the mobile air conditioner is not connected to the exhaust duct, the heat generated by the air conditioning cooling cannot be discharged to the outside. It is necessary to control the operating status of the mobile air conditioner. On the one hand, it can ensure that the mobile air conditioner can operate normally, and on the other hand, it can ensure that the sampling value of the ambient temperature of the mobile air conditioner is consistent with the actual ambient temperature.

[0031] In an embodiment of the present application, a mobile air conditioner is provided, comprising:

[0032] A housing, wherein a first air inlet, an air outlet, a second air inlet and an air outlet are provided on the housing, wherein the first air inlet and the air outlet 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;

[0033] The indoor unit includes a first heat exchanger and a first fan, the first heat exchanger and the first fan are arranged in the indoor side air duct, the first fan drives the indoor air to enter the indoor side air duct from the first air inlet to exchange heat with the first heat exchanger, and then be discharged from the air outlet;

[0034] The outdoor unit includes a compressor, a second heat exchanger and a second fan. The compressor, the second heat exchanger and the second fan are arranged in the outdoor air duct. The second fan drives the airflow from the second air inlet into the outdoor air duct to exchange heat with the second heat exchanger and then is discharged from the exhaust port.

[0035] An exhaust pipe, the exhaust pipe is detachably installed at the exhaust port;

[0036] Controller, the controller is configured as:

[0037] When the mobile air conditioner operates in a cooling mode and the compressor is turned on, obtaining a first temperature at the second air inlet;

[0038] When the compressor runs for a first start time, obtaining a second temperature at the second air inlet;

[0039] judging whether the mobile air conditioner is equipped with an exhaust duct according to the relationship between the first temperature and the second temperature;

[0040] If it is determined that the mobile air conditioner is not equipped with an exhaust duct, the distance between the mobile air conditioner and the obstacle is obtained, and the operating state of the mobile air conditioner is controlled according to the distance.

[0041] Optionally, in the embodiment of the present application, an ambient temperature sensor is provided inside the chassis of the mobile air conditioner, and a display panel is provided on the body of the mobile air conditioner. The ambient temperature sensor is used to detect the indoor temperature, and the display panel is used to display the indoor temperature.

[0042] In one embodiment of the present application, the mobile air conditioner comprises:

[0043] Distance detection component;

[0044] The distance detection component is installed at one side of the second air inlet, and is used to detect the distance between the mobile air conditioner and the obstacle.

[0045] In an embodiment of the present application, the controller in the mobile air conditioner is configured to control the mobile air conditioner. Figure 1 The figure shows the steps of controlling the mobile air conditioner. Figure 1 As shown, the method includes steps S110 to S140.

[0046] S110, when the mobile air conditioner operates in a cooling mode and the compressor is turned on, obtaining a first temperature at a second air inlet.

[0047] When it is determined that the mobile air conditioner operates in a cooling mode, it is detected whether the compressor is turned on, and when the compressor is turned on, the first temperature at the second air inlet is obtained.

[0048] The temperature at the second air inlet may be obtained by a temperature sensor disposed near the second air inlet.

[0049] The first temperature refers to the temperature at the second air inlet when the mobile air conditioner operates in a cooling mode and the compressor is turned on.

[0050] S120: When the compressor runs for a first start time, obtain a second temperature at the second air inlet.

[0051] The first opening duration is used to indicate a time node for obtaining the second temperature at the second air inlet, that is, the timing for obtaining the second temperature at the second air inlet is determined according to the operating duration of the compressor.

[0052] The first on-time can be calculated from the time when the compressor starts to start, and the second temperature is obtained after the compressor runs for the first on-time. Alternatively, the first on-time is calculated from the time when the first temperature is obtained, and the timing starts after the first temperature is obtained, and the second temperature is obtained after the first on-time.

[0053] The first temperature and the second temperature are used to distinguish the temperature of the second air inlet at different time nodes.

[0054] S130: Determine whether the mobile air conditioner is equipped with an exhaust duct based on the relationship between the first temperature and the second temperature.

[0055] According to the relationship between the first temperature and the second temperature, it refers to the relationship between the first temperature and the second temperature. As time changes, the second temperature will change compared to the first temperature, and the temperature change is related to the operating state of the mobile air conditioner. The temperature change of the structural components of the mobile air conditioner is related to whether the exhaust duct is installed. Therefore, according to the relationship between the second temperature and the first temperature, it can be judged whether the mobile air conditioner is installed with an exhaust duct.

[0056] In normal use scenarios, mobile air conditioners need to be equipped with exhaust ducts, one end of which is connected to the chassis of the mobile air conditioner and the other end is connected to the outdoors. The function of the exhaust duct is to discharge the heat generated by the mobile air conditioner during cooling to the outdoors.

[0057] However, in some scenarios, the placement of the mobile air conditioner conflicts with the length of the exhaust duct, that is, the distance between the placement of the mobile air conditioner and the window is greater than the length of the exhaust duct, so the user will choose not to use an external exhaust duct, but to discharge the heat generated by the mobile air conditioner during cooling out of the body through the air outlet of the mobile air conditioner.

[0058] When the mobile air conditioner is not equipped with an exhaust duct, it is necessary to control the operating state of the mobile air conditioner according to the specific usage of the mobile air conditioner.

[0059] S140: If it is determined that the mobile air conditioner is not equipped with an exhaust duct, the distance between the mobile air conditioner and the obstacle is obtained, and the operating state of the mobile air conditioner is controlled according to the distance.

[0060] When it is determined that the mobile air conditioner is not equipped with an exhaust duct, the distance between the mobile air conditioner and the obstacle is obtained, and the operating state of the mobile air conditioner is controlled according to the distance.

[0061] Specifically, the distance between the mobile air conditioner and the obstacle can be obtained by a distance detection component arranged on the housing of the mobile air conditioner. The distance detection component can be an infrared sensor. The infrared sensor is a sensing device having a pair of infrared signal transmitting diodes and infrared signal receiving diodes. The infrared sensor emits a beam of infrared light, which forms a reflected light after irradiating the obstacle. The reflected light is reflected to the infrared sensor to form a reflected signal. The infrared sensor calculates the time difference between the transmitted signal and the reflected signal through a signal processor, and outputs the distance between the mobile air conditioner and the obstacle after being processed by the signal processor.

[0062] After obtaining the distance between the mobile air conditioner and the obstacle, if the distance between the mobile air conditioner and the obstacle is too close, the air outlet track of the air outlet will be affected by the obstacle, and the hot air discharged from the air outlet will hit the obstacle to produce return air, which will then blow back into the body, causing the temperature inside the body to rise. As the running time increases, the temperature inside the body becomes higher and higher, and may even endanger the operating safety of the mobile air conditioner.

[0063] If the distance between the mobile air conditioner and the obstacle meets the control condition, the operating state of the mobile air conditioner is controlled to ensure the safe operation of the mobile air conditioner.

[0064] Optionally, an ambient temperature sensor and a display panel are provided inside the mobile air conditioner, wherein the ambient temperature sensor is used to detect the indoor temperature, and the display panel is used to display the indoor temperature. When the mobile air conditioner is too close to an obstacle, the return air will affect the internal temperature of the body, and since the ambient temperature sensor is provided inside the mobile air conditioner body, the internal temperature increase will affect the sampling accuracy of the ambient temperature sensor, resulting in the indoor temperature read by the ambient temperature sensor being inaccurate and being too different from the actual indoor temperature, causing a poor user experience.

[0065] In this embodiment, by controlling the operating state of the mobile air conditioner, the sampling accuracy of the ambient temperature sensor can be guaranteed, so that the detected indoor temperature is not much different from the actual indoor temperature, which is beneficial to improving the user experience.

[0066] In the embodiment of the present application, since the installation positions of the second air inlet and the exhaust duct are close, by repeatedly detecting the temperature at the second air inlet of the mobile air conditioner and according to the temperature change at the air inlet, it is possible to determine whether the mobile air conditioner is installed with an exhaust duct. When it is determined that the mobile air conditioner is not installed with an exhaust duct, the placement of the mobile air conditioner may affect the air outlet trajectory of the exhausted hot air, causing the internal temperature of the body to be too high, affecting the operational safety of the mobile air conditioner. Therefore, the distance between the mobile air conditioner and the obstacle is obtained through the distance detection component, the operational state of the mobile air conditioner is controlled according to the distance, and the operation of the mobile air conditioner is adjusted based on the use environment of the mobile air conditioner, thereby ensuring the operational safety of the mobile air conditioner to a certain extent.

[0067] It should be noted that although the steps of the method in the present application are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.

[0068] In this embodiment, Figure 2 The figure shows the steps of judging whether the mobile air conditioner is equipped with an exhaust duct according to the temperature at the second air inlet. Figure 2 As shown, in step S130, it is determined whether the mobile air conditioner is equipped with an exhaust duct according to the relationship between the first temperature and the second temperature, including steps S210 to S230.

[0069] S210: If the second temperature is lower than the first temperature, it is determined that the mobile air conditioner is equipped with an exhaust duct.

[0070] If the second temperature is lower than the first temperature, it means that the indoor temperature starts to drop after the first start time, and the current indoor temperature is lower than the indoor temperature when the compressor starts to run. There are no factors that will cause the temperature to rise indoors, so it can be determined that the mobile air conditioner is equipped with an exhaust duct, which can discharge the hot air generated by the mobile air conditioner to the outside, so the temperature at the second air inlet drops.

[0071] When it is determined that the mobile air conditioner is equipped with an exhaust duct, the operating state of the mobile air conditioner is not controlled, and the current operating state of the mobile air conditioner is maintained.

[0072] S220: If the second temperature is greater than the first temperature, it is determined that the mobile air conditioner is not equipped with an exhaust duct.

[0073] If the second temperature is greater than the first temperature, it means that the indoor temperature starts to rise after the first opening time. This is because the heat generated by the mobile air conditioner during cooling is discharged through the air outlet. Therefore, it is determined that the mobile air conditioner is not equipped with an exhaust duct.

[0074] Under normal circumstances, the mobile air conditioner is running in cooling mode, and the indoor temperature should be on a downward trend. Based on this phenomenon, if the second temperature is greater than the first temperature, it can be determined that the mobile air conditioner is not equipped with an exhaust duct.

[0075] S230, if the second temperature is equal to the first temperature, determine whether the mobile air conditioner is equipped with an exhaust duct based on the relationship between the third temperature and the first temperature, the third temperature being the temperature of the second air inlet after being at a preset time.

[0076] If the second temperature is equal to the first temperature, it cannot be determined whether the mobile air conditioner is equipped with an exhaust duct. This may be because the indoor area is too large, resulting in an insignificant cooling effect. In order to eliminate variables, after a preset time, the temperature at the second air inlet is re-detected to obtain a third temperature, and based on the relationship between the third temperature and the first temperature, it is determined whether the mobile air conditioner is equipped with an exhaust duct.

[0077] If it is determined that the mobile air conditioner is not equipped with an exhaust duct, the distance between the mobile air conditioner and the obstacle is detected by the distance detection component, and whether the operating state of the mobile air conditioner needs to be controlled is determined based on the distance.

[0078] If it is determined that the mobile air conditioner is equipped with an exhaust duct, the mobile air conditioner is maintained in an operating state.

[0079] In this embodiment, by comparing the first temperature and the second temperature, it is determined whether the mobile air conditioner is installed with an exhaust duct, and then according to whether the exhaust duct is installed, it is determined whether to control the mobile air conditioner to change the operating state of the mobile air conditioner, thereby achieving the effect of timely adjusting the operating state of the mobile air conditioner, and to a certain extent, can effectively guarantee the operating state of the mobile air conditioner.

[0080] As an optional implementation, when it is detected that the mobile air conditioner is running in cooling mode and the compressor is in the on state, the exhaust duct status judgment flag is read, and the exhaust duct status judgment flag is used to determine whether it is necessary to detect the temperature at the second air inlet; the exhaust duct status judgment result is read, and the operating status control process is executed on the mobile air conditioner based on the exhaust duct status judgment result.

[0081] The exhaust duct status determination flag indicates whether the operation of determining the installation status of the exhaust duct of the mobile air conditioner has been performed. If the exhaust duct status determination flag is 0, it indicates that the operation of determining the installation status of the exhaust duct of the mobile air conditioner has not been performed; if the exhaust duct status determination flag is 1, it indicates that the operation of determining the installation status of the exhaust duct of the mobile air conditioner has been performed and the exhaust duct status determination result has been obtained.

[0082] The operation of determining the installation status of the exhaust pipe of the mobile air conditioner is as follows:

[0083] When it is detected that the mobile air conditioner is operating in a cooling mode and the compressor is in an on state, detecting a first temperature at the second air inlet;

[0084] After the first opening time, detecting a second temperature at the second air inlet;

[0085] According to the relationship between the first temperature and the second temperature, it is determined whether the mobile air conditioner is equipped with an exhaust duct.

[0086] In the embodiment of the present application, by setting the exhaust duct status judgment flag, the judgment process of the exhaust duct installation status is saved, which is used to repeatedly enter the process of judging whether the exhaust duct is installed, thereby improving the control efficiency of the mobile air conditioner.

[0087] In this embodiment, Figure 3 The figure shows the steps of judging whether the mobile air conditioner is equipped with an exhaust duct according to the temperature at the second air inlet. Figure 3 As shown, in step S230, if the second temperature is equal to the first temperature, it is determined whether the mobile air conditioner is equipped with an exhaust duct according to the relationship between the third temperature and the first temperature, including S310 to S320.

[0088] S310: When the compressor runs for a second start time, detect a third temperature at the second air inlet.

[0089] If the second temperature is equal to the first temperature, after the second opening time has elapsed, a third temperature at the second air inlet is detected.

[0090] The second on-time may be the total time from when the compressor is turned on to when the third temperature is detected, wherein the second on-temperature should be greater than the first on-time.

[0091] Alternatively, the second opening time length indicates the time length from the detection of the second temperature to the detection of the third temperature. The value of the second opening time length can be set according to specific circumstances.

[0092] S320: If the third temperature is less than or equal to the first temperature, it is determined that the mobile air conditioner is equipped with an exhaust duct.

[0093] If the third temperature is less than or equal to the first temperature, indicating that the indoor temperature begins to drop, it is determined that the mobile device is equipped with an exhaust duct.

[0094] In the embodiment of the present application, when the second temperature is equal to the first temperature, it is impossible to accurately determine whether the mobile air conditioner is installed with an exhaust duct. In order to improve the accuracy of the exhaust duct installation determination, when the compressor runs for the second start time, the third temperature at the second air inlet is detected, and the relationship between the third temperature and the first temperature is used to determine whether the mobile air conditioner is installed with an exhaust duct, which can improve the accuracy of determining whether the mobile air conditioner is installed with an exhaust duct to a certain extent.

[0095] In this embodiment, Figure 4 The figure shows the steps of controlling the operating state of the mobile air conditioner according to the distance between the mobile air conditioner and the obstacle. Figure 4 As shown, in step S140, if it is determined that the mobile air conditioner is not equipped with an exhaust duct, the distance between the mobile air conditioner and the obstacle is obtained, and the operating state of the mobile air conditioner is controlled according to the distance, including steps S410 to S420.

[0096] S410, detecting the distance between the mobile air conditioner and the obstacle by using a distance detection component.

[0097] S420, controlling the operating state of the mobile air conditioner according to the relationship between the distance and the upper limit value of the distance.

[0098] Specifically, the distance detection component is used to detect the distance between the mobile air conditioner and the obstacle. Optionally, the distance detection component uses an infrared sensor.

[0099] The distance detection component is arranged near the second air inlet on the outer side of the chassis. Optionally, the distance detection component and the chassis installation plane have an angle less than 90°. This arrangement can determine whether the mobile air conditioner is equipped with an exhaust duct when the distance detection component performs distance detection, which improves the convenience of exhaust duct detection to a certain extent.

[0100] The upper limit value of the distance represents the safe distance between the mobile air conditioner and the obstacle. The safe distance means that the air outlet trajectory of the air outlet of the mobile air conditioner will not be affected by the obstacle.

[0101] Based on the upper limit of the distance, according to the relationship between the distance and the upper limit of the distance, it can be concluded whether the current position of the mobile air conditioner will affect the operating safety of the mobile air conditioner body. If it affects the operating safety of the body, the operating state of the mobile air conditioner needs to be controlled.

[0102] In this embodiment, distance detection is performed by a distance detection component, and based on the relationship between the detected distance and the upper limit value of the distance, it is quickly determined whether the operating state of the mobile air conditioner needs to be adjusted, which can improve the control response efficiency of the mobile air conditioner to a certain extent.

[0103] In this embodiment, Figure 5 The figure shows the steps of controlling the operating state of the mobile air conditioner according to the relationship between the distance and the upper limit value of the distance. Figure 5 As shown, in step S420, the operating state of the mobile air conditioner is controlled according to the relationship between the distance and the upper limit value of the distance, including steps S510 to S530.

[0104] S510: If the distance is greater than the upper limit of the distance, the current operating state of the mobile air conditioner is maintained.

[0105] S520: If the distance is less than or equal to the upper limit of the distance, the current operating time of the compressor and the temperature of the condenser are obtained.

[0106] S530, controlling the operating state of the mobile air conditioner according to the operating time and the temperature.

[0107] The upper limit of the distance indicates the safe distance between the mobile air conditioner and the obstacle. If the distance between the mobile air conditioner and the obstacle is greater than the upper limit of the distance, the operation state of the mobile air conditioner does not need to be controlled, and the current operation state of the mobile air conditioner is only maintained.

[0108] If the distance between the mobile air conditioner and the obstacle is less than or equal to the upper limit of the distance, the operating state of the mobile air conditioner needs to be adjusted accordingly according to the operating time of the compressor and the temperature of the condenser to achieve a precise control effect.

[0109] In this embodiment, the current operating condition of the mobile air conditioner is obtained based on the distance between the mobile air conditioner and the obstacle, the operating time of the compressor and the temperature of the condenser. The operating state of the mobile air conditioner is adjusted according to different operating conditions to ensure that the operating condition of the mobile air conditioner is not too extreme, which is conducive to the safe operation of the mobile air conditioner.

[0110] In this embodiment, Figure 6 The figure shows the steps of controlling the operating state of a mobile air conditioner according to the operating time and temperature. Figure 6 As shown, in step S530, the operating state of the mobile air conditioner is controlled according to the operating time and temperature, including steps S610 to S620.

[0111] S610: If the running time is greater than the upper limit of the running time, the compressor is controlled to stop running.

[0112] S620: If the operating time is less than or equal to the upper limit of the operating time, the temperature of the condenser is obtained, and according to the temperature of the condenser, the compressor is controlled to stop running and the second fan is controlled to rotate at a preset speed.

[0113] The running time refers to the length of time the compressor runs continuously. If the running time is greater than the upper limit of the running time, the compressor will be controlled to stop running to reduce the heat generated by the compressor and try not to let the temperature inside the machine body rise too quickly.

[0114] If the operating time is less than or equal to the upper limit of the operating time, the temperature of the condenser is acquired, and it is determined whether the operating state of the mobile air conditioner needs to be adjusted according to the temperature of the condenser.

[0115] It should be noted that the operating time of the compressor refers to the total time of continuous operation of the compressor. The first on-time and the second on-time of the compressor refer to the current operating time of the compressor meeting the condition for detecting the temperature at the second air inlet.

[0116] The running time is greater than the first on time and the second on time.

[0117] As an optional implementation, the first on-time and the second on-time can be timed together with the running time. Assuming that the time from detecting the third temperature to obtaining the running time of the compressor is the third time, the total running time of the compressor is equal to the first on-time plus the second on-time plus the third time.

[0118] Optionally, the timing process of the operating time is separated from the timing processes of the first on time and the second on time, and the operating time of the compressor refers to the duration of the process from turning on the compressor to obtaining the operating time of the compressor.

[0119] In this embodiment, corresponding adjustment strategies are set for different situations according to the running time of the compressor. The mobile air conditioner is controlled according to specific situations, which can improve the control effect of the mobile air conditioner and avoid damage to the internal body of the air conditioner.

[0120] In this embodiment, in step S620, if the running time is less than or equal to the upper limit of the running time, the temperature of the condenser is obtained, and according to the temperature of the condenser, the compressor is controlled to stop running and the second fan is controlled to rotate at a preset speed. The method further includes:

[0121] The stop time of the compressor is timed, and if the stop time is greater than the first stop time upper limit, the compressor is controlled to start.

[0122] Specifically, when the running time is greater than the upper limit of the time, the compressor is forced to stop running, and the stop time of the compressor is counted. If the stop time is greater than the upper limit of the stop time, the compressor is controlled to start.

[0123] After the compressor is turned on, the stop time is reset to zero.

[0124] In this embodiment, by timing the stop time of the compressor, if the compressor stops running for a period of time that reaches the upper limit of the stop time, the compressor is forced to start, ensuring that the mobile air conditioner can operate the cooling mode normally, ensuring the cooling effect, and improving the user experience.

[0125] In this embodiment, Figure 7 The figure shows the steps of controlling the operating state of the mobile air conditioner according to the temperature of the condenser. Figure 7 As shown, in step S620, if the operating time is less than or equal to the upper limit of the operating time, the temperature of the condenser is obtained, and according to the temperature of the condenser, the compressor is controlled to stop running and the second fan is controlled to rotate at a preset speed, including steps S710 to S720.

[0126] S710: Obtain the temperature of the condenser.

[0127] S720: If the temperature is greater than the first temperature upper limit, the compressor is controlled to stop running and the second fan is controlled to rotate at a preset speed.

[0128] Specifically, when the temperature of the condenser is greater than the first temperature upper limit value, the compressor is controlled to stop running and the second fan is controlled to rotate at a preset speed.

[0129] When the compressor stops running, it will stop generating heat. The rotation of the second fan can dissipate the remaining heat inside the machine body, which is helpful to quickly reduce the temperature inside the machine body.

[0130] In this embodiment, the operating state of the mobile air conditioner is adjusted by the temperature of the condenser, which is beneficial to lowering the temperature inside the mobile air conditioner, ensuring the normal operation of the internal components of the body, and ensuring the operating safety of the body to a certain extent.

[0131] In this embodiment, Figure 8 The figure shows the steps of controlling the operating state of the mobile air conditioner according to the temperature of the condenser. Figure 8 As shown, in step S720, if the temperature is greater than the first temperature upper limit value, the compressor is controlled to stop running and the second fan is controlled to rotate at a preset speed. The method further includes steps S810 to S820.

[0132] S810, after a preset time, detecting the current temperature of the condenser.

[0133] S820: If the current temperature is lower than the second temperature upper limit, the current operating state of the mobile air conditioner is maintained.

[0134] After the compressor stops running for a preset time, the current temperature of the condenser is detected. If the current temperature is less than the second temperature upper limit value, it means that the temperature inside the body has dropped and the mobile air conditioner can run normally, and the current running state of the mobile air conditioner is maintained.

[0135] Optionally, an operation instruction from a user is received, and the mobile air conditioner is controlled to perform a corresponding operation according to the operation instruction from the user.

[0136] In the embodiment of the present application, the second upper temperature limit is set and whether the current state of the mobile air conditioner can operate normally is detected to ensure the safe operation of the mobile air conditioner.

[0137] Reference Fig. 9 , combined with the specific implementation of the control method of the mobile air conditioner, the technical solution of the present application is described in detail.

[0138] S910, the mobile air conditioner operates in cooling mode and the compressor is turned on;

[0139] When it is detected that the mobile air conditioner is running in cooling mode and the compressor is turned on, step S920 is executed. If the mobile air conditioner is not running in cooling mode or the compressor is not turned on, the current operating state of the mobile air conditioner is maintained.

[0140] S920, obtaining a first temperature at a second air inlet;

[0141] It is determined that the mobile air conditioner operates in a cooling mode and the compressor is turned on, and a first temperature at a second air inlet of the mobile air conditioner is obtained.

[0142] S930, obtaining a second temperature at a second air inlet;

[0143] When the compressor runs for a first start time, a second temperature at the second air inlet is obtained.

[0144] The first on-time is used to distinguish the time difference between the first temperature and the second temperature. The first on-time can be the operating time of the compressor from the time the first temperature is obtained to the time the second temperature is obtained, and the first on-time can be set to 3 minutes; or, the first on-time represents the operating time of the compressor from the time the compressor is turned on to the time the second temperature is obtained; for example, let the operating time of the compressor from the time the compressor is turned on to the time the first temperature is obtained be X, and the operating time from the time the first temperature is obtained to the time the second temperature is obtained be Y. It can be understood that the first operating time is equal to X+Y, and Y can be set to 3 minutes.

[0145] It should be noted that after obtaining the second temperature at the second air inlet, three results can be obtained according to the relationship between the first temperature and the second temperature. The first result is that the second temperature is less than the first temperature, corresponding to step S940. The second result is that the second temperature is equal to the first temperature, corresponding to step S950. The third result is that the second temperature is greater than the first temperature, corresponding to step S960. According to the above three results, it is determined whether the mobile air conditioner is equipped with an exhaust duct.

[0146] Based on the first result, the step of determining whether the mobile air conditioner is equipped with an exhaust duct includes S940 to S942.

[0147] S940, the second temperature is lower than the first temperature;

[0148] S942, determining whether the mobile air conditioner is equipped with an exhaust duct;

[0149] If the second temperature is lower than the first temperature, it means that the indoor temperature has started to drop. Under the premise that the mobile air conditioner is already running in cooling mode, there are no other factors indoors that may cause the indoor temperature to rise. It can be concluded that the hot air generated by the mobile air conditioner's cooling is not discharged indoors but is discharged outdoors through the exhaust duct. Therefore, it is determined that the mobile air conditioner is equipped with an exhaust duct.

[0150] Based on the second result, the step of determining whether the mobile air conditioner is equipped with an exhaust duct includes S950 to S954 and S942.

[0151] S950, the second temperature is equal to the first temperature;

[0152] S952, obtaining a third temperature at the second air inlet;

[0153] S954, the third temperature is less than or equal to the first temperature;

[0154] S942, determining whether the mobile air conditioner is equipped with an exhaust duct;

[0155] If the second temperature is equal to the first temperature, it is still impossible to determine whether the mobile air conditioner is equipped with an exhaust duct. In order to reduce irrelevant variables, after the compressor runs for the second start-up time, the third temperature at the second air inlet is obtained. According to the relationship between the third temperature and the first temperature, if the third temperature is less than or equal to the first temperature, it is determined that the mobile air conditioner is equipped with an exhaust duct.

[0156] The second on-time is set to distinguish the time difference between the second temperature and the third temperature. The second on-time can be the operating time of the compressor from the time the second temperature is obtained to the time the third temperature is obtained, so the second on-time can be set to 2 minutes; or the second on-time can be the operating time of the compressor from the time the second temperature is turned on to the time the third temperature is obtained.

[0157] Based on the third result, the step of determining whether the mobile air conditioner is equipped with an exhaust duct includes S960 to S970.

[0158] S960, the second temperature is greater than the first temperature;

[0159] S970, determining that the mobile air conditioner is not equipped with an exhaust duct;

[0160] If the second temperature is greater than the first temperature, it means that the indoor temperature begins to rise. Under the premise that the mobile air conditioner is running in cooling mode, there are still factors that cause the temperature to rise indoors. Based on the current situation, it is believed that the mobile air conditioner is not equipped with an exhaust duct, causing the heat generated by refrigeration to be discharged along with the hot air. Therefore, it can be determined that the mobile air conditioner is not equipped with an exhaust duct.

[0161] S980, detecting the distance between the mobile air conditioner and the obstacle by a distance detection component;

[0162] S981, the distance is less than or equal to the upper limit of the distance;

[0163] The distance detection component installed on the mobile air conditioner detects the distance between the mobile air conditioner and the obstacle. If the distance is less than or equal to the upper limit value, step S982 is executed. The upper limit value of the distance can be set to 1m.

[0164] S982, the operating time of the compressor is greater than the upper limit of the operating time;

[0165] The operation time of the compressor is obtained. If the operation time is greater than the upper limit of the operation time, steps S990 to S996 are executed; if the operation time is less than or equal to the upper limit of the operation time, steps S983 to S900 are executed.

[0166] The operating time refers to the length of time the compressor runs continuously from the time it is turned on. The upper limit of the operating time can be set to 10 minutes.

[0167] Specifically, if the operating time of the compressor is greater than the operating time, steps S990 to S996 are executed.

[0168] S990, control the compressor to stop running;

[0169] S992, timing the stop time;

[0170] S994, the stop duration is greater than the first stop duration upper limit;

[0171] S996, control the compressor to start;

[0172] After the compressor is controlled to stop running, the stop time of the compressor is timed, and if the stop time is greater than the first stop upper limit value, the compressor is controlled to start.

[0173] Among them, the first stop upper limit value can be set to 1 minute.

[0174] Optionally, the stop time is 45 seconds, and the current indoor temperature is read by the ambient temperature sensor and displayed on the display panel of the mobile air conditioner.

[0175] Specifically, if the operating time of the compressor is less than or equal to the upper limit of the operating time, steps S983 to S900 are executed.

[0176] S983, obtaining the temperature of the condenser;

[0177] S984, the temperature is greater than the first temperature upper limit;

[0178] S985, controlling the compressor to stop running and controlling the second fan to rotate at a preset speed;
