Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of air conditioners, and particularly relates to a mobile air conditioner. BACKGROUND

[0002] In the use process of the mobile air conditioner, the heat generated by the mobile air conditioner shell usually needs to be discharged to the outdoor space through the exhaust pipe. In a specific use environment, the mobile air conditioner may not be connected with the exhaust pipe. 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 pipe, but is blown back to the inside of the shell along with the air circulation or encounters an obstacle, thereby affecting the sampling of the environment temperature in the shell and causing a difference between the sampling temperature and the actual temperature in the room, which seriously affects the operation of the shell.

[0003] In the prior art, the temperature difference between the indoor environment temperature and the outdoor temperature of the mobile air conditioner is detected, and corresponding control is performed on the mobile air conditioner according to the temperature difference between the indoor environment temperature and the outdoor temperature. However, for the use condition of not being connected with the exhaust pipe, the control effect is not high, and even the operation safety of the mobile air conditioner is affected. SUMMARY

[0004] The application provides a mobile air conditioner, which improves the operation effect of the mobile air conditioner when the exhaust pipe is not connected.

[0005] A mobile air conditioner comprises:

[0006] a shell, wherein a first air inlet, an air outlet, a second air inlet and an exhaust port are arranged on the shell, the first air inlet and the air outlet are connected to form an indoor side air duct, and the second air inlet and the exhaust port are connected to form an outdoor side air duct;

[0007] an indoor unit, wherein a first heat exchanger and a first fan are arranged in the indoor side air duct, and the first fan drives indoor air to enter the indoor side air duct from the first air inlet, exchanges heat with the first heat exchanger, and then is discharged from the air outlet;

[0008] an outdoor unit, wherein a compressor, a second heat exchanger and a second fan are arranged in the outdoor side air duct, and the second fan drives airflow to enter the outdoor side air duct from the second air inlet, exchanges heat with the second heat exchanger, and then is discharged from the exhaust port;

[0009] an exhaust pipe, wherein the exhaust pipe is detachably installed at the exhaust port;

[0010] a controller, wherein the controller is configured to:

[0011] acquiring an operation mode of the mobile air conditioner;

[0012] when the operation mode is the cooling mode, judging whether the exhaust pipe is installed at the exhaust outlet;

[0013] if the exhaust pipe is not installed at the exhaust outlet, acquiring a distance between the mobile air conditioner and an obstacle;

[0014] if the distance is less than or equal to an upper limit value of the distance, acquiring a running time length of the compressor;

[0015] adjusting a running state of the compressor and / or the second fan according to the running time length.

[0016] In the present application, by configuring a controller in the mobile air conditioner, when the controller detects that the mobile air conditioner is in the cooling mode, it is detected whether the exhaust pipe is installed at the exhaust outlet of the mobile air conditioner. When the mobile air conditioner is not installed with the exhaust pipe, the distance between the mobile air conditioner and the obstacle is detected. If the distance is less than or equal to the upper limit value of the distance, the running time length of the compressor is acquired. According to the running time length of the compressor, the running state of the mobile air conditioner is adjusted. In particular, whether the mobile air conditioner is installed with the exhaust pipe and the distance to the surrounding obstacle are judged, so as to dynamically control the running state of the mobile air conditioner, to ensure that the heat dissipation effect of the mobile air conditioner in the cooling mode does not affect the running safety of the mobile air conditioner, and to further improve the control effect on the mobile air conditioner.

[0017] Other features and advantages of the present application will become apparent from the following detailed description, or will be learned by practice of the present application.

[0018] It should be understood that the general description above and the following detailed description are only exemplary and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0027] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art.

[0028] Moreover, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the

[0029] The block diagrams in the drawings show only the functionality of the features and can not imply a necessity of any particular physical or architectural arrangement. That is, the functionality of the features can be implemented in software, hardware, or a combination thereof, and can be implemented in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0030] The flow diagrams shown in the drawings are merely examples of possible flow diagrams and are not necessarily meant to include all of the steps and operations, nor are the steps and operations necessarily meant to be performed in the order shown. For example, some steps and operations can be broken down further, while some steps and operations can be combined or partially combined, and thus the actual order of performance can vary from the order shown.

[0031] The mobile air conditioner provided by the present application will be described in detail below in conjunction with the specific embodiments.

[0032] It should be noted that the mobile air conditioner refers to an air conditioner in which an indoor unit and an outdoor unit are combined into one, without an outdoor unit, and which can be placed anywhere in a room to achieve the effect of cooling a local area through the refrigeration of a compressor and the discharge of hot air through an exhaust pipe.

[0033] The mobile air conditioner is characterized in that it can be moved at will, and a user can adjust the position of the mobile air conditioner in the room according to needs. When the mobile air conditioner is used for refrigeration, an exhaust pipe is usually connected to discharge the heat from the air outlet outside. When the mobile air conditioner is not connected to the exhaust pipe, the heat generated by the air conditioner during refrigeration cannot be discharged outside, and the operation state of the mobile air conditioner needs to be controlled, on the one hand, to ensure that the mobile air conditioner can operate normally, and on the other hand, to ensure that the sampling value of the ambient temperature of the mobile air conditioner is consistent with the actual ambient temperature.

[0034] In the embodiments of the present application, a mobile air conditioner is provided, comprising:

[0035] a housing, the housing being provided with a first air inlet, an air outlet, a second air inlet and an air exhaust, the first air inlet and the air outlet being connected to form an indoor air duct, and the second air inlet and the air exhaust being connected to form an outdoor air duct;

[0036] 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 air duct, the first fan driving indoor air to enter the indoor air duct from the first air inlet, exchange heat with the first heat exchanger, and then be discharged from the air outlet;

[0037] 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 being arranged in the outdoor air duct, the second fan driving air flow to enter the outdoor air duct from the second air inlet, exchange heat with the second heat exchanger, and then be discharged from the air exhaust;

[0038] an exhaust pipe, the exhaust pipe being detachably installed at the air exhaust;

[0039] a controller, the controller being configured to:

[0040] obtain an operation mode of the mobile air conditioner;

[0041] when the operation mode is a refrigeration mode, determine whether the exhaust pipe is installed at the air exhaust;

[0042] if the exhaust pipe is not installed at the air exhaust, obtain a distance between the mobile air conditioner and an obstacle;

[0043] if the distance is less than or equal to an upper limit value, obtain a running time of the compressor;

[0044] Adjust the operating status of the compressor and / or the second fan according to the running time.

[0045] The portable air conditioner in this embodiment of the application also includes:

[0046] The distance detection component is placed at a preset angle relative to the exhaust pipe installation position on the portable air conditioner. The distance detection component is used to detect whether the portable air conditioner is equipped with an exhaust pipe when the portable air conditioner is in cooling mode, and to detect the distance between the portable air conditioner and obstacles.

[0047] The distance detection component is used to detect whether an exhaust pipe is installed on the portable air conditioner, and to detect the distance between the portable air conditioner and surrounding obstacles.

[0048] Optionally, the distance detection component is an infrared sensor. The infrared sensor has a pair of infrared signal emitting diodes and infrared signal receiving diodes. When performing distance detection, it emits a beam of infrared light, which forms emitted light after illuminating the obstacle. By processing the time difference between the emitted and received infrared signals through a signal processor, the distance between the portable air conditioner and the obstacle can be calculated.

[0049] The distance detection component is located on the exterior of the portable air conditioner's casing, adjacent to the location where the exhaust duct is installed. To detect whether the portable air conditioner has an exhaust duct installed, the distance detection component needs to be positioned at a preset angle.

[0050] Optionally, the distance detection component has a rotation function. The controller issues a rotation command, and the distance detection component rotates to the corresponding detection angle according to the detection angle included in the rotation command, and performs distance detection at that detection angle.

[0051] Specifically, in conventional solutions, the distance detection component is placed perpendicular to the outer plane of the housing. In this embodiment, the placement of the distance detection component differs from the conventional solution in that it is not installed perpendicularly to the outside of the housing, but rather at a preset angle, and the distance detection component is positioned opposite the exhaust duct. For example, when the distance detection component is an infrared sensor, the position emitting infrared light is opposite to the installation position of the exhaust duct, and the distance between them is a fixed value.

[0052] It should be noted that when the distance detection component detects the distance between the portable air conditioner and an obstacle, what is actually detected is the distance between the distance detection component and the obstacle. However, since the distance detection component is set on the portable air conditioner and the size difference between the distance detection component and the portable air conditioner is too large, it is equivalent to detecting the distance between the portable air conditioner and the obstacle.

[0053] That is, when a portable air conditioner is equipped with an exhaust duct, the exhaust duct is the closest obstacle to the detection component, and the distance between the exhaust duct and the distance detection component is a fixed value. If the distance obtained by the distance detection component is a fixed value or falls within a fixed range, then the portable air conditioner is considered to be equipped with an exhaust duct.

[0054] In this embodiment, by improving the portable air conditioner, it is possible to control the portable air conditioner in specific scenarios to adjust its operating status and ensure its safe operation.

[0055] In one embodiment of this application, a controller in a portable air conditioner is configured to control the portable air conditioner. The controller executes a control method for the portable air conditioner, such as... Figure 1 The method shown includes steps S110 to S150.

[0056] S110, obtain the operating mode of the portable air conditioner.

[0057] S120, when the operating mode is cooling mode, determines whether an exhaust pipe is installed at the exhaust vent.

[0058] When a portable air conditioner is running in cooling mode, the heat generated inside the casing needs to be exhausted outdoors through the exhaust pipe to ensure that no heat remains inside the casing, thus preventing the internal structure of the casing from overheating and affecting normal operation.

[0059] Portable air conditioners are typically used in living rooms, bedrooms, or kitchens, requiring an external exhaust duct to expel heat outdoors and ensure safe and reliable operation of the system. However, in certain scenarios, due to duct length limitations, users may be unable to connect the exhaust duct to the outside, resulting in the portable air conditioner operating without an exhaust duct.

[0060] To ensure the normal operation of portable air conditioners, it is necessary to adjust the operating status of the portable air conditioner according to whether an exhaust pipe is installed at the exhaust vent.

[0061] In this embodiment, if the portable air conditioner is in the start-up state, the current operating mode is detected. When the portable air conditioner is in cooling mode, it is determined whether an exhaust pipe is installed at the exhaust vent of the portable air conditioner. Optionally, if the portable air conditioner performs an operating mode switching operation during operation, it is detected whether it has switched to cooling mode. When it has switched to cooling mode, it is detected whether an exhaust pipe is installed at the exhaust vent of the portable air conditioner.

[0062] One way to detect whether a portable air conditioner has an exhaust duct installed is to install a sensor at the exhaust duct and use the sensor to detect the installation status of the exhaust duct.

[0063] S130, if no exhaust pipe is installed at the exhaust vent, obtain the distance between the portable air conditioner and the obstacle.

[0064] When a portable air conditioner is not equipped with an exhaust duct, the heat generated inside the casing is expelled through the air outlet. If there are obstacles around the portable air conditioner and the distance between the air conditioner and these obstacles is too close, the airflow trajectory of the outlet may be affected. The hot air expelled from the outlet may be obstructed by the obstacles, causing backflow that is then blown back into the casing. This results in a change in the internal temperature of the casing, causing the temperature sensor inside the casing to register an increase. As the operating time increases, the temperature value collected by the temperature sensor becomes increasingly higher, which differs from the actual indoor ambient temperature and can negatively impact the user experience to some extent.

[0065] Optionally, by installing an infrared sensor on the portable air conditioner, the distance between the portable air conditioner and surrounding obstacles can be obtained through distance detection. An infrared sensor is a sensing device with a pair of infrared signal emitting diodes and infrared signal receiving diodes. The infrared sensor emits a beam of infrared light, which, upon hitting an object, forms a reflected signal that is reflected back to the infrared sensor. A signal processor calculates the time difference between the emitted and received signals, and after processing, outputs the distance between the portable sensor and the obstacle.

[0066] The timing of detecting the distance between the portable air conditioner and obstacles can be set according to the actual application scenario. Optionally, a detection cycle can be set to periodically detect the distance between the portable air conditioner and obstacles.

[0067] S140, if the distance is less than or equal to the upper limit of the distance, obtain the running time of the compressor.

[0068] The upper limit of distance indicates the safe distance between the portable air conditioner and obstacles. When the portable air conditioner is not connected to an exhaust duct, if the distance between the portable air conditioner and the obstacle is greater than the upper limit of distance, the hot air discharged from the vent will not be affected by the obstacle and will not be blown back into the casing. The compressor is located inside the portable air conditioner. When the distance between the air conditioner and the obstacle is less than or equal to the upper limit of distance during movement, the compressor's operating time is recorded.

[0069] It should be noted that when the compressor is not turned on, the compressor's operating time is 0.

[0070] In this embodiment, the compressor's runtime refers to the duration of a single continuous operation of the compressor. When the portable air conditioner is powered off or stops operating, or when the compressor stops running, the compressor's runtime is reset to zero. When the compressor starts up again, the timing program restarts.

[0071] S150, adjusts the operating status of the compressor and / or the second fan according to the running time.

[0072] After obtaining the compressor's runtime, the operating status of the compressor and / or the second fan is adjusted according to the runtime. In this embodiment, corresponding adjustments need to be made based on the runtime to achieve the desired control effect.

[0073] The second fan is installed in the outdoor unit, which includes a compressor, a second heat exchanger, and a second fan. The compressor, the second heat exchanger, and the second fan are installed in the outdoor side duct. The second fan drives the airflow to enter the outdoor side duct from the second air inlet and exchange heat with the second heat exchanger before being discharged from the exhaust outlet.

[0074] By setting a preset upper limit for runtime, the operating status of the portable air conditioner is dynamically adjusted based on the relationship between the runtime and the upper limit.

[0075] In this embodiment, if the portable air conditioner is detected to be operating in cooling mode, it checks whether the portable air conditioner has an exhaust duct installed. When it is detected that the portable air conditioner does not have an exhaust duct installed, the operating state of the portable air conditioner is controlled by the detected distance between the portable air conditioner and the obstacle. If the distance is less than or equal to the upper limit, the compressor's operating time is obtained, and the operating state of the portable air conditioner is changed according to the compressor's operating time; if the distance is greater than the upper limit, the current operating state of the portable air conditioner is maintained. This embodiment sets corresponding control conditions for the usage scenario of the portable air conditioner, thereby dynamically controlling the operating state of the portable air conditioner, which improves the control effect of the portable air conditioner to a certain extent. In addition, while ensuring that the portable air conditioner has a good heat dissipation effect, it does not affect the operational safety of the portable air conditioner, further improving the operational safety of the portable air conditioner.

[0076] It should be noted that although the steps of the method in this application are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.

[0077] In this embodiment, Figure 2 The procedure for checking the installation of exhaust ducts is shown. For example... Figure 2 As shown, in step S120, when the operating mode is cooling mode, the method for determining whether an exhaust pipe is installed at the exhaust vent includes steps S210 to S230.

[0078] S210, set the angle of the distance detection component to the initial angle, which is the angle between the distance detection component and the mounting plane on the portable air conditioner.

[0079] Optionally, the distance detection component is a ranging component installed on the portable air conditioner, including but not limited to infrared sensors.

[0080] In this embodiment, the distance detection component and the mounting plane of the portable air conditioner have an angle not equal to 90°. The initial angle refers to the angle between the distance detection component and the mounting plane when the portable air conditioner leaves the factory; optionally, the initial angle is set to 30°.

[0081] When the distance detection component is installed on the portable air conditioner at an initial angle and the portable air conditioner is equipped with an exhaust pipe, the distance detection component performs distance detection to obtain the distance between the distance detection component and the exhaust pipe, and this distance is maintained within a fixed range.

[0082] By setting the installation angle of the distance detection component to the initial angle, it is possible to quickly detect whether a portable air conditioner is equipped with an exhaust pipe, thereby enabling the rapid execution of subsequent processes.

[0083] S220, distance detection is performed by the distance detection component to obtain the relative distance between the distance detection component and the obstacle.

[0084] S230, if the relative distance is greater than the upper limit of the distance, it is determined that the portable air conditioner is not equipped with an exhaust pipe.

[0085] It should be noted that the distance detection component is installed adjacent to the exhaust duct, and the two are placed in a relative relationship. When the exhaust duct is installed on the portable air conditioner, the straight-line distance between the exhaust duct and the distance detection component is a fixed value or falls within a fixed range.

[0086] When the distance detection component starts detecting the distance between the portable air conditioner and the obstacle, the actual distance detected is the distance between the distance detection component and the obstacle. Since the distance detection component is installed on the portable air conditioner, it is assumed that the detected distance is the distance between the portable air conditioner and the obstacle.

[0087] When the portable air conditioner is in cooling mode, if the exhaust duct is installed on the portable air conditioner, the exhaust duct is the closest obstacle to the distance detection component.

[0088] When the distance detection component starts performing distance detection, if the relative distance obtained is greater than the upper limit of the distance, it is determined that no exhaust pipe is installed at the exhaust vent of the portable air conditioner.

[0089] The upper limit of distance refers to the maximum distance between the exhaust duct and the exhaust duct detected by the distance detection component when the exhaust duct is installed.

[0090] In this embodiment, the distance detection component is installed on the portable air conditioner at an initial angle. Based on the characteristic that the distance between the distance detection component and the exhaust duct is a fixed value when the portable air conditioner is equipped with an exhaust duct, the distance detection component can quickly detect whether the portable air conditioner has an exhaust duct installed. This allows subsequent control processes to be executed based on the exhaust duct installation result, thus accelerating the control speed of the portable air conditioner to some extent. Furthermore, by setting the installation angle of the distance detection component, the installation of the exhaust duct can be intelligently detected without requiring modifications to the exhaust duct installation method.

[0091] In this embodiment, Figure 3 A flowchart illustrating the steps involved in detecting the distance between a portable air conditioner and an obstacle is shown. Figure 3 As shown, in step S130, if no exhaust pipe is installed at the exhaust vent, the distance between the portable air conditioner and the obstacle is obtained, including steps S310 to S320.

[0092] S310, when no exhaust pipe is installed at the exhaust vent, a periodic timer with a preset detection cycle is set.

[0093] S320: When the timing node of the periodic timer reaches the preset detection period, the distance between the portable air conditioner and the obstacle is obtained.

[0094] Specifically, when it is detected that no exhaust pipe is installed at the exhaust vent of the portable air conditioner, a periodic timer is set. The periodic timer counts according to a preset detection period. When the periodic timer reaches the timing node, the distance between the portable air conditioner and the obstacle is detected again. After the distance is obtained, the timing timer is reset to zero and the timing program is restarted.

[0095] Optionally, the preset detection period is set to 20 min. When the period timer reaches 20 min, the distance detection is repeated.

[0096] In this embodiment, by setting a preset detection cycle, the distance between the portable air conditioner and the obstacle is periodically detected. During operation, this prevents the portable air conditioner from being moved by humans, which could cause changes in the distance between the portable air conditioner and the obstacle and affect the heat dissipation effect of the portable air conditioner.

[0097] In this embodiment, Figure 4 A flowchart illustrating the process of detecting the distance between a portable air conditioner and an obstacle is shown. Figure 4As shown, in step S130, if no exhaust pipe is installed at the exhaust vent, the distance between the portable air conditioner and the obstacle is obtained, including the following steps S410 to S430.

[0098] S410: Set multiple detection angles and obtain the diagonal distance between the portable air conditioner and the obstacle at each detection angle. The detection angle represents the relative relationship between the portable air conditioner and the obstacle.

[0099] In this embodiment, the device for performing distance detection is mounted on the portable air conditioner at a fixed angle, which is set as the initial angle.

[0100] Figure 5 A diagram showing the relative positions of the portable air conditioner and obstacles is provided. Figure 5 As shown, taking right triangle ABC as an example, ∠C is the right angle, point A is the placement position of the portable air conditioner 500, and line BC is the plane where the obstacle 510 is located. ∠A represents the initial angle at which the distance detection component is installed on the portable air conditioner. Therefore, the actual distance obtained by the portable air conditioner 500 during distance detection is the length of the hypotenuse of ∠A, i.e., line AB. However, the length of line AB is not the actual distance between the portable air conditioner 500 and the obstacle 510. Mathematical calculations are needed to obtain the actual distance between the portable air conditioner and the obstacle.

[0101] The detection angle is used to distinguish the relative positions of the portable air conditioner 500 and the same obstacle at different locations.

[0102] In this embodiment, an initial angle is preset, wherein the initial angle is ≥1°. At the initial angle, the diagonal distance between the portable air conditioner 500 and the obstacle 510 is detected.

[0103] The detection angle is based on the initial angle and increases by a fixed value clockwise. For example, if the initial angle is set to 30° and the fixed increase is 90°, then detection angle 1 is 120°, detection angle 2 is 210°, and detection angle 3 is 300°. Optionally, the detection angle can decrease gradually by a fixed value counterclockwise.

[0104] In this embodiment, optionally, the distance detection is performed 4 times. If a distance detection is performed at the initial angle, then 3 detection angles are set, gradually increasing by 90°.

[0105] Distance is detected at each detection angle to obtain the corresponding diagonal distance. For example, detection angle 1 corresponds to diagonal distance 1, and detection angle 2 corresponds to diagonal distance 2.

[0106] S420, perform trigonometric function calculations on the diagonal distance to obtain the straight-line distance between the portable air conditioner and the obstacle.

[0107] Reference Figure 5 As stated above, point A is the portable air conditioner 500, the plane containing BC is the plane containing the obstacle 510, the diagonal distance is the length of the hypotenuse AC, and the actual distance between the portable air conditioner 500 and the obstacle 510 is the length of the adjacent side AB of ∠A.

[0108] For each detection angle, trigonometric functions are used to calculate the diagonal distance to obtain the straight-line distance. The straight-line distance is the perpendicular distance between the portable air conditioner 500 and the obstacle 510.

[0109] S430 sums up all straight-line distances and calculates the average value, using the average value as the distance between the portable air conditioner and the obstacle.

[0110] The straight-line distances for all detection angles are calculated, and all straight-line distances are summed. The average value is then calculated based on the sum and used as the distance between the portable air conditioner and the obstacle.

[0111] As an alternative implementation, all straight-line distances are compared, the largest and smallest straight-line distances are removed, the sum of all remaining straight-line distances is calculated, and the average value is calculated based on this sum. The final average value is used as the distance between the portable air conditioner and the obstacle.

[0112] For example, as an optional implementation, distance detection is performed four times: once at the initial angle, once at detection angle 2, once at detection angle 3, and once at detection angle 4. This yields four diagonal distances, which, after trigonometric function calculations, result in four straight-line distances: straight-line distance 1, straight-line distance 2, straight-line distance 3, and straight-line distance 4. Straight-line distance 1 corresponds to the initial angle, straight-line distance 2 corresponds to detection angle 2, straight-line distance 3 corresponds to detection angle 3, and straight-line distance 4 corresponds to detection angle 4.

[0113] Let the straight-line distance 1 be the largest and the straight-line distance 4 be the smallest. Then remove the straight-line distances 1 and 4 and calculate the average value L = (straight-line distance 2 + straight-line distance 3) / 2. Use the average value as the distance between the portable air conditioner and the obstacle.

[0114] In this embodiment, by setting multiple detection angles and performing distance detection at the corresponding angles, the possibility of the portable air conditioner having an obstacle only in a certain direction is eliminated. Unlike conventional methods, an initial angle is set, and multiple detection angles are used to detect and calculate the straight-line distance at each detection angle. Extreme data among the multiple straight-line distances are eliminated through statistical methods, making the final distance more consistent with the real environment and further improving the accuracy of the detected distance.

[0115] In this embodiment,Figure 6 A flowchart illustrating the steps involved in controlling the operation of a portable air conditioner is provided. Figure 6 As shown, in step S150, the operating status of the compressor and / or the second fan is adjusted according to the running time, including steps S610 to S620.

[0116] S610: If the runtime exceeds the upper limit, the compressor will be stopped.

[0117] 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 the running speed of the second fan is changed according to the temperature.

[0118] Specifically, runtime refers to the length of time the compressor runs continuously. When the runtime exceeds the upper limit, the compressor is stopped to adjust the operating status of the portable air conditioner; when the runtime is less than or equal to the upper limit, the condenser temperature is obtained, and the operating speed of the second fan is adjusted according to the condenser temperature to change the operating status of the portable air conditioner.

[0119] Optionally, in this embodiment, the maximum duration is set to 10 minutes.

[0120] The compressor's function is to compress the refrigerant in the air conditioner's refrigerant circuit, transforming the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gaseous refrigerant. When the compressor is forcibly stopped, it ceases heat generation, allowing previously generated heat to dissipate from the interior of the unit without affecting its internal structure.

[0121] High-temperature, high-pressure gaseous refrigerant enters the condenser, where heat exchange occurs, dissipating the heat from the gaseous refrigerant into the air. The temperature of the condenser is then measured, and its operating status is determined based on this temperature. When the condenser temperature exceeds the upper limit, the heat dissipation rate is adjusted by changing the operating speed of the second fan, which to some extent ensures the safe operation of the portable air conditioner.

[0122] In this embodiment, by adjusting the compressor's operating time, corresponding adjustment strategies are set for different situations, and the portable air conditioner is controlled for specific situations, thereby improving the control effect of the portable air conditioner and avoiding damage to the internal casing.

[0123] In this embodiment, Figure 7 A flowchart illustrating the steps involved in controlling the operation of a portable air conditioner is shown. Figure 7 As shown, in step S610, if the runtime exceeds the upper limit, the compressor is controlled to stop running, including steps S710 to S720.

[0124] S710 times the compressor's stop time to obtain the stop duration.

[0125] S720: If the stop time exceeds the upper limit of the stop time, control the compressor to start and reset the stop time.

[0126] When the runtime exceeds the maximum duration, the compressor is forcibly stopped, and the compressor's stop time is timed. When the stop duration exceeds the maximum stop duration, the compressor is restarted, and the stop duration is reset.

[0127] In this embodiment, optionally, the upper limit of the stop time is set to 60 seconds. After the compressor has stopped running for 60 seconds, the compressor is controlled to start and the stop time is reset.

[0128] In this embodiment, by timing the compressor's stop time, when the compressor's stop time reaches the upper limit, the compressor is forcibly turned on to ensure that the portable air conditioner can operate normally in cooling mode.

[0129] In some implementations of 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 the running speed of the second fan is changed according to the temperature, including:

[0130] The temperature of the condenser is obtained. If the temperature is greater than the upper limit, the compressor is stopped and the second fan is controlled to run at the preset speed.

[0131] Specifically, when the compressor's stop time is less than or equal to the upper limit of the stop time, the condenser temperature is obtained. When the temperature exceeds the upper limit, the compressor is stopped, and the second fan is controlled to run at a preset fan speed. In this embodiment, optionally, the upper limit of the temperature is set to 70°C. When the condenser temperature exceeds 70°C, the compressor is stopped, and the second fan runs at its highest speed, thereby enabling rapid heat dissipation and ensuring that the temperature inside the casing is somewhat consistent with the ambient temperature.

[0132] In this embodiment, when the compressor's running time is less than the upper limit of the running time, the portable air conditioner is controlled by another control logic. Specifically, the temperature of the condenser is obtained to determine whether the operating status of the portable air conditioner needs to be adjusted. This enables control of the portable air conditioner in various scenarios, which improves the control effect of the portable air conditioner to a certain extent and ensures the safe operation of the portable air conditioner.

[0133] In some optional embodiments of this example, after adjusting the operating state of the portable air conditioner according to the running time in step S140, the method includes:

[0134] If the distance is greater than the upper limit, the portable air conditioner will maintain its current operating status.

[0135] When the portable air conditioner is running in cooling mode and no exhaust pipe is installed, after distance detection, if the distance between the portable air conditioner and the obstacle is greater than the upper limit, it means that the air outlet trajectory of the portable air conditioner will not be affected by the obstacle. Maintaining the operation of the portable air conditioner under the current conditions can ensure its normal operation and, to a certain extent, guarantee the user experience.

[0136] In some optional embodiments of this example, after adjusting the operating status of the compressor and / or the second fan according to the runtime in step S150, the method includes:

[0137] The ambient temperature is sampled and displayed using a temperature sensor.

[0138] In this embodiment, a temperature sensor is installed inside the portable air conditioner to sample the ambient temperature. Optionally, a display panel can be provided on the portable sensor to display the ambient temperature.

[0139] In some alternative implementations, the temperature sensor is set to sample and update within a preset time period. During this process, the temperature inside the casing can be reduced after the portable air conditioner is controlled, so that the sampled ambient temperature tends to be consistent with the actual ambient temperature, ensuring the accuracy of the ambient temperature detected by the temperature sensor for a certain period of time.

[0140] Optionally, the preset time period is set to 15 seconds. The temperature sensor samples the ambient temperature periodically at 15-second intervals to accurately update the current ambient temperature.

[0141] In this embodiment, the ambient temperature is sampled and displayed by a temperature sensor. Users can adjust the operation status or placement of the portable air conditioner according to their needs based on the displayed ambient temperature, which can improve the user experience to some extent.

[0145] S803, timing T0 = 0;

[0146] T0 refers to the time during which the portable air conditioner operates in cooling mode. When T0 = 0, it indicates that the portable air conditioner has entered cooling mode for the first time. Specifically, this means that the portable air conditioner starts operating in cooling mode or switches from other modes to cooling mode.

[0147] S805, Check whether an exhaust pipe is installed at the exhaust vent of the portable air conditioner;

[0148] Distance detection is performed using a distance detection component. If the detected distance is less than or equal to the upper limit of the relative distance, it indicates that the portable air conditioner is not equipped with an exhaust pipe. The upper limit of the distance is set to 1m.

[0149] S807, obtain the distance between the portable air conditioner and obstacles;

[0150] S809, the distance is greater than the maximum distance limit;

[0151] If the obtained distance is less than or equal to the upper limit of distance, the compressor's running time is obtained. If the detected distance is greater than the upper limit of distance, the current operating state of the portable air conditioner is maintained.

[0152] S811, T0 ≥ preset detection cycle time node;

[0153] Time T0 is set, and when T0 reaches the timing node of the preset detection cycle, T0 is reset and the distance between the portable air conditioner and the obstacle is re-detected. The detection cycle can be set to 20 min.

[0154] S813, obtain the compressor's runtime;

[0155] When T0 is less than the preset detection cycle node, the compressor's running time is obtained.

[0156] S815, runtime exceeds the maximum duration limit;

[0157] When the runtime exceeds the upper limit, the compressor is stopped and the stop time is timed. The upper limit is set to 10 min. When the runtime is less than or equal to the upper limit, the temperature of the condenser is obtained.

[0158] S851, obtains the temperature of the condenser;

[0159] When the runtime is less than or equal to the upper limit, obtain the temperature of the condenser.

[0160] S853, temperature exceeds the upper temperature limit;

[0161] The temperature of the condenser is obtained, and subsequent steps are performed based on the temperature of the condenser. When the temperature of the condenser is greater than the upper temperature limit, the compressor is stopped and the operating speed of the second fan is changed. The upper temperature limit of the condenser is set to 70°. Optionally, the second fan is controlled to run at the highest wind speed.

[0162] S855 controls the compressor to stop and changes the operating speed of the second fan;

[0163] When the temperature of the condenser exceeds the upper temperature limit, the stationary compressor stops and the operating speed of the second fan is changed.

[0164] S861 controls the compressor to stop running and times the duration of compressor stoppage;

[0165] When the compressor's running time exceeds the upper limit, the compressor is controlled to stop running, and the stop time of the compressor is timed.

[0166] S863, the stop duration is greater than the maximum stop duration value;

[0167] If the stop time is less than or equal to the upper limit of the stop time, the compressor will continue to be controlled to stop running.

[0168] S865 controls the compressor to start and reset the stop duration;

[0169] When the stop duration exceeds the maximum stop duration value, the compressor is controlled to start and the stop time is reset. The maximum stop duration value is set to 60 seconds.

[0170] S800, maintains the operation of the portable air conditioner;

[0171] If the operating status of the portable air conditioner does not meet the judgment conditions, then the current operating status of the portable air conditioner shall be maintained.
