Description

Technical Field

[0001] This application relates to the field of vehicle refrigerator technology, and more particularly to a defrosting method for vehicle refrigerators, vehicle refrigerators, vehicles, and storage media. Background Technology

[0002] As an important product in the automotive parts market, car refrigerators are experiencing continuous market demand growth. Car refrigerators not only provide drivers and passengers with the convenience of cold drinks and food, but also enhance the comfort of long-distance travel to some extent. Currently, to maintain the cooling efficiency of car refrigerators, regular defrosting is necessary. During defrosting, the frost on the evaporator melts into water, which is usually collected in a special evaporation dish and drained outside the car refrigerator through a drainage system.

[0016] The target defrosting heating time is determined based on the initial defrosting heating time, the vehicle's continuous running time, the first duration, and the second duration, wherein the target defrosting heating time is longer than the initial defrosting heating time.

[0017] The initial defrosting cycle of the vehicle refrigerator is determined as the target defrosting cycle.

[0018] In one embodiment, if the vehicle is in a stable driving state, determining the target defrost cycle and / or target defrost heating duration for the vehicle refrigerator includes:

[0019] If the vehicle remains in a stable driving state within the preset defrosting time, the initial defrosting cycle is determined as the target defrosting cycle of the vehicle refrigerator, and / or the initial defrosting heating time is determined as the target defrosting cycle of the vehicle refrigerator.

[0020] In one embodiment, defrosting of the vehicle refrigerator includes:

[0021] Obtain the height of the liquid medium in the evaporation dish of the vehicle refrigerator;

[0022] If the liquid level is below the set value, the operating mode of the vehicle refrigerator is determined; if the vehicle refrigerator is in defrost mode, the driving status of the vehicle is determined; if the vehicle is in a vibrating driving state, the vehicle refrigerator is controlled to switch from defrost mode to cooling mode; or...

[0023] If the liquid medium level is higher than or equal to the set value, obtain the operating mode of the vehicle refrigerator; if the vehicle refrigerator is in defrosting mode, control the vehicle refrigerator to switch from defrosting mode to cooling mode.

[0024] In one embodiment, if the vehicle refrigerator is in defrost mode, after controlling the vehicle refrigerator to switch from defrost mode to cooling mode, the method further includes:

[0025] After preset the cooling time, obtain the height of the solid medium in the evaporation dish;

[0026] If the solid medium height is higher than or equal to the set value, control the vehicle refrigerator to switch from cooling mode to defrosting mode;

[0027] Alternatively, if the solid medium height is lower than the set value, the vehicle refrigerator can be kept in cooling mode.

[0028] In one embodiment, determining the driving status of the vehicle where the in-vehicle refrigerator is located includes:

[0029] Obtain the vehicle's tilt angle and acceleration;

[0030] The vehicle's driving status is determined based on the tilt angle and acceleration.

[0037] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the defrosting method for a vehicle refrigerator as described above.

[0038] This application obtains the operating mode of the vehicle refrigerator. If the vehicle refrigerator is in defrost mode, it determines the driving status of the vehicle. If the vehicle is in a vibrating driving state, it controls the vehicle refrigerator to switch to cooling mode. Since there is a liquid medium in the evaporator dish when the vehicle refrigerator is in defrost mode, if the vehicle is in a vibrating driving state, the liquid medium in the evaporator dish may overflow due to shaking or tilting. Therefore, controlling the vehicle refrigerator to stop defrosting and switch to cooling mode when vibrating driving state is detected can mitigate the increase of new liquid medium and reduce the liquid medium in the evaporator dish. This avoids the risk of liquid medium overflowing from the evaporator dish when the vehicle is vibrating or driving unevenly, thus improving the user experience of the vehicle refrigerator.

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0050] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0051] With the increasing popularity of car travel and outdoor activities, car refrigerators, as an important product in the automotive parts market, are experiencing continuous growth in market demand. Car refrigerators not only provide drivers and passengers with the convenience of cold drinks and food, but also enhance the comfort of long-distance travel to some extent.

[0052] Currently, in order to maintain the cooling efficiency of vehicle refrigerators, regular defrosting is required. During defrosting, the frost on the evaporator melts into water, and this liquid medium is usually collected in a special evaporation dish and drained outside the vehicle refrigerator through a drainage system.

[0053] However, in actual use, especially when the vehicle is traveling and encounters frequent vibrations or uneven road surfaces causing significant tilting, the liquid medium in the evaporation dish may overflow due to shaking or tilting. Once the liquid overflows, it not only contaminates the food and beverages inside the car refrigerator but may also damage the internal electronic components, potentially causing short circuits and other safety hazards. Furthermore, liquid overflow reduces the user experience, increases customer complaints, and negatively impacts the product's market reputation and brand image. Therefore, effectively solving the problem of liquid overflow during defrosting of air-cooled car refrigerators due to vehicle vibration or tilting has become a critical issue that urgently needs to be addressed in the current research and development of car refrigerator technology.

[0054] To address the aforementioned issues, this application proposes a defrosting method for a vehicle-mounted refrigerator. The main technical solution includes: acquiring the operating mode of the vehicle-mounted refrigerator; if the vehicle-mounted refrigerator is in defrosting mode, determining the driving status of the vehicle where the refrigerator is located; if the vehicle is in a vibrating driving state, controlling the vehicle-mounted refrigerator to switch from defrosting mode to cooling mode.

[0055] This application obtains the operating mode of the vehicle refrigerator. If the vehicle refrigerator is in defrost mode, the application determines the driving status of the vehicle. If the vehicle is in a vibrating driving state, the application controls the vehicle refrigerator to switch to cooling mode. Since a liquid medium exists in the evaporator dish when the vehicle refrigerator is in defrost mode, this liquid medium may overflow due to shaking or tilting if the vehicle is in a vibrating driving state. Therefore, when a vibrating driving state is detected, the application controls the vehicle refrigerator to stop defrosting and switch to cooling mode. The main purpose of cooling mode is to lower the internal temperature of the vehicle refrigerator by absorbing heat through refrigerant circulation and evaporation. When the vehicle refrigerator is in cooling mode, the temperature of the evaporator surface decreases, which reduces the formation of frost on the evaporator and thus reduces the amount of liquid medium generated during defrosting. In cooling mode, the air temperature inside the vehicle refrigerator decreases, and the humidity also decreases accordingly. If a small amount of liquid medium exists inside the vehicle refrigerator, the lower temperature and humidity help evaporate this moisture, thereby reducing the amount of liquid medium present. By switching the car refrigerator from defrosting mode to cooling mode, the risk of liquid media overflowing due to shaking during vibrating driving conditions can be avoided. This also prevents the addition of new liquid media and reduces the amount of liquid media in the evaporation dish, thus mitigating the problem of liquid media overflowing from the evaporation dish of the car refrigerator when the vehicle vibrates or is driven unevenly, thereby improving the user experience of the car refrigerator.

[0056] It should be noted that the vehicle refrigerator of this application can be an air-cooled vehicle refrigerator. The working principle of an air-cooled vehicle refrigerator mainly involves a built-in fan promoting the circulation of cold air inside the refrigerator to achieve a cooling effect. However, while this mechanism brings efficient cooling, it also presents some technical challenges. Especially during the defrosting process, frost accumulates on the evaporator inside the air-cooled vehicle refrigerator. To maintain the cooling efficiency of the vehicle refrigerator, regular defrosting is necessary. During defrosting, the frost on the evaporator melts into water, and this liquid medium is usually collected in a special evaporation dish and drained outside the vehicle refrigerator through a drainage system. The vehicle refrigerator of this application can also be other types of vehicle refrigerators, such as a direct-cooling vehicle refrigerator, which relies on natural convection cooling through the evaporator. Compared to a direct-cooling vehicle refrigerator, an air-cooled vehicle refrigerator cools faster; therefore, this application preferably uses an air-cooled vehicle refrigerator. In addition to cooling, the air-cooled vehicle refrigerator of this application also has a heating function.

[0057] The air-cooled vehicle refrigerator of this application includes a compressor, condenser, dryer filter, capillary tube, evaporator, and return pipe assembly. During the refrigeration process, the compressor is the heart of the refrigeration system, providing power to the entire system. It compresses the low-pressure gaseous refrigerant at room temperature into a high-temperature, high-pressure gaseous refrigerant. The condenser dissipates heat from the refrigeration system, condensing the high-temperature, high-pressure gas discharged from the compressor into a low-temperature, high-pressure liquid. The dryer filter absorbs moisture and impurities in the system, preventing ice blockage and dirt blockage. The capillary tube acts as a throttling and pressure-reducing element. The evaporator employs a dual-evaporator design, where the refrigerant changes from liquid to gas, absorbing heat from the interior of the refrigerator to achieve the refrigeration effect. The return pipe assembly contains the low-temperature gaseous refrigerant from the evaporator, which exchanges heat with the capillary tube and becomes a low-temperature gaseous refrigerant.

[0058] In practical applications, when the air-cooled vehicle refrigerator is in cooling mode, if the temperature sensor inside the vehicle refrigerator has not reached the stop temperature, the compressor will start and the bottom cooling fan will run to start cooling until the temperature sensor inside the vehicle refrigerator reaches the stop temperature, at which point cooling will stop.

[0059] It's important to note that after a period of operation, frost will gradually form on the evaporator surface of a frost-cooled car refrigerator. Frost has a very low thermal conductivity, making it difficult to conduct heat and increasing the thermal resistance between the evaporator surface and the air, thus reducing the evaporator's heat transfer performance. Therefore, to ensure the cooling effect of the car refrigerator, defrosting is necessary in a timely manner. Specifically, a temperature sensor can be used to detect the evaporator temperature. When the evaporator temperature drops to a certain value, the defrosting program is triggered, controlling the defrosting cycle and heating time to ensure the defrosting process occurs at the appropriate time. During defrosting, the car refrigerator's compressor will stop working, and the fan will also stop running, ceasing the circulation of cold air into the refrigerator. The defrost valve of the refrigeration cycle system will open, allowing hot refrigerant to enter the evaporator. The heater installed near the evaporator will start working, providing heat to melt the frost on the evaporator surface. The melted water will drip into an evaporation dish located below the evaporator and be drained to the outside of the car refrigerator through the drainage system, preventing water accumulation from affecting the normal operation of the refrigerator. After defrosting is complete, when the temperature sensor detects that the evaporator temperature has risen to a certain level, indicating that the frost has completely melted, the heater stops operating, thus stopping defrosting. The refrigerator then resumes its normal cooling cycle. This process switches between defrosting and cooling modes.

[0060] Based on this, this application provides a defrosting method for a vehicle refrigerator, referring to... Figure 1 , Figure 1 This is a flowchart illustrating some embodiments of the defrosting method for a vehicle-mounted refrigerator according to this application.

[0061] In some embodiments of this application, the defrosting method for a vehicle-mounted refrigerator includes steps S10 to S30:

[0062] Step S10: Obtain the operating mode of the vehicle refrigerator.

[0063] It should be noted that the operating mode of the car refrigerator can be one of the following: cooling mode, heating mode, or defrosting mode.

[0064] In one feasible implementation, the timing of acquiring the operating mode of the vehicle refrigerator can be timed, real-time, or when set conditions are met, such as when the liquid medium height in the evaporation dish of the vehicle refrigerator is higher than or equal to a set value, or when the duration of the vehicle refrigerator in defrosting mode reaches a set duration, so as to promptly perform subsequent defrosting control of the vehicle refrigerator based on the acquired operating mode.

[0065] In another feasible implementation, the method for obtaining the operating mode of the vehicle refrigerator includes, but is not limited to, one or more of the following methods:

[0066] The operating mode of the car refrigerator can be determined through its control panel. Specifically, most car refrigerators have indicator lights or displays on the control panel to show the current operating mode. You can directly observe the information on these indicators or displays to determine the operating mode. Alternatively, you can switch between different operating modes by pressing specific buttons on the panel and view the currently selected mode on the display.

[0067] The operating mode of the in-car refrigerator is also obtained through the vehicle's central control system. Specifically, if the in-car refrigerator is integrated with the vehicle's central control system, its operating mode can be viewed and controlled via the central control screen. The central control screen includes a menu or option to display the refrigerator's status and settings. Alternatively, the operating mode can be remotely viewed and controlled via a mobile application. Users need to download and install the corresponding in-car app and connect to the refrigerator via Bluetooth or Wi-Fi. The refrigerator's operating mode can then be viewed within the application.

[0068] The operating mode of the in-vehicle refrigerator can also be found on the vehicle information display screen. Specifically, some models will display the operating mode of the in-vehicle refrigerator on the vehicle's information display screen, such as the instrument panel or head-up display system. Users can find out the operating mode of the in-vehicle refrigerator by observing the information display screen.

[0069] Step S20: If the vehicle refrigerator is in defrost mode, determine the driving status of the vehicle where the vehicle refrigerator is located.

[0070] It's important to note that defrosting mode is a special operating mode inside a car refrigerator designed to remove frost that forms on the evaporator surface due to cooling. During operation, the evaporator surface temperature is low, causing water vapor in the air to easily condense and form frost. As the frost thickens, the evaporator's heat transfer performance decreases, leading to reduced cooling efficiency. Therefore, car refrigerators need to periodically enter defrosting mode to remove frost and maintain cooling efficiency. When a car refrigerator enters defrosting mode, the cooling cycle is temporarily stopped, and the defrosting heater is activated. The defrosting heater is typically installed near the evaporator and melts the frost on its surface into water. The melted water drips into an evaporation dish located below the evaporator and is drained through the refrigerator's drainage system, preventing water accumulation inside. During defrosting, the car refrigerator may temporarily stop supplying cold air, causing the internal temperature to rise slightly. After defrosting mode ends, the car refrigerator automatically resumes the cooling cycle, continuing to supply cold air to the interior.

[0071] The defrosting mode can be triggered in several ways: Car refrigerators typically have a temperature sensor inside to monitor the temperature of the evaporator surface. When the temperature sensor detects that the evaporator surface temperature is too low or the frost is too thick, the defrosting mode is automatically triggered. Alternatively, a defrosting timer can be set to control the defrosting cycle and heating duration. The timer will automatically start the defrosting mode at preset time intervals, regardless of whether there is frost on the evaporator surface. The defrosting mode can also be determined based on the vehicle's driving status or the height of the solid medium in the evaporator dish inside the car refrigerator.

[0072] It should be noted that driving status refers to the state of a vehicle during travel due to road conditions. Road conditions include road surface smoothness, slope, and curvature. By determining the road conditions encountered by the vehicle carrying the car refrigerator, the vehicle's driving status can be determined. Driving status can be categorized into two types: smooth driving status and vibrating driving status. When a vehicle is in a smooth driving status, it indicates that the road surface is relatively smooth or has no slope. When a vehicle is in a vibrating driving status, it indicates that the road surface is uneven or has a significant slope.

[0073] If the car refrigerator is in defrost mode, the frost on the evaporator surface melts into water. This melted water drips into the evaporation dish located below the evaporator and is drained through the refrigerator's drainage system, preventing water accumulation inside the refrigerator. Because the evaporation dish contains a liquid medium when the car refrigerator is in defrost mode, if the vehicle is vibrating or shaking, the liquid medium in the evaporation dish may overflow due to shaking or tilting. Therefore, it is necessary to obtain the driving status of the vehicle containing the car refrigerator to further assess whether there is a risk of liquid medium overflowing from the evaporation dish.

[0074] In one feasible implementation, the vehicle's driving status can be determined by the on-board terminal and sent to the on-board refrigerator, enabling the on-board refrigerator to obtain the vehicle's driving status and switch subsequent operating modes. Alternatively, the vehicle's driving status can be determined directly by the on-board refrigerator after processing the data collected by the sensors.

[0075] Step S30: If the vehicle is in a vibrating driving state, control the vehicle refrigerator to switch from defrosting mode to cooling mode.

[0076] If the vehicle is vibrating while driving, there is a risk of liquid overflow from the evaporator. In this case, the car refrigerator should be switched to cooling mode. The main purpose of cooling mode is to lower the internal temperature of the car refrigerator by absorbing heat through refrigerant circulation and evaporation. When the car refrigerator is in cooling mode, the surface temperature of the evaporator will decrease, which will reduce the formation of frost on the evaporator and thus reduce the amount of liquid generated during defrosting. In cooling mode, the air temperature and humidity inside the car refrigerator will also decrease. If there is a small amount of liquid inside the car refrigerator, the lower temperature and humidity will help evaporate this moisture, thereby reducing the amount of liquid. By switching the car refrigerator from defrosting mode to cooling mode, the risk of liquid overflow due to shaking during vibrating driving can be avoided. This prevents the addition of new liquid and reduces the amount of liquid in the evaporator, mitigating the problem of liquid overflow from the evaporator when the vehicle is vibrating or driving unevenly, thus improving the user experience of the car refrigerator.

[0077] In this embodiment, by acquiring the operating mode of the vehicle refrigerator, if the vehicle refrigerator is in defrost mode, the driving status of the vehicle where the refrigerator is located is determined; if the vehicle is in a vibrating driving state, the vehicle refrigerator is controlled to switch to cooling mode. Since there is a liquid medium in the evaporation dish when the vehicle refrigerator is in defrost mode, if the vehicle is in a vibrating driving state, the liquid medium in the evaporation dish may overflow due to shaking or tilting. Therefore, when the vehicle is detected to be in a vibrating driving state, controlling the vehicle refrigerator to stop defrosting and switch to cooling mode can alleviate the increase of new liquid medium and reduce the liquid medium in the evaporation dish. This avoids the risk of liquid medium overflowing from the evaporation dish of the vehicle refrigerator when the vehicle is vibrating or driving unevenly, thus improving the user experience of the vehicle refrigerator.

[0078] Reference Figure 2 In some embodiments of this application, if the vehicle is in a vibrating driving state, after controlling the vehicle refrigerator to switch from defrosting mode to cooling mode, the method further includes:

[0079] Step S110: If the vehicle is in a stable driving state, determine the target defrost cycle and / or target defrost heating time of the vehicle refrigerator.

[0080] When a car refrigerator is in cooling mode, the temperature of the evaporator surface decreases, reducing frost formation and consequently reducing the amount of liquid medium produced during defrosting. Frost buildup on the evaporator causes the liquid medium in the evaporation dish to gradually solidify, affecting the refrigerator's subsequent cooling efficiency and effect. Therefore, after switching the car refrigerator to cooling mode, it's necessary to reassess the vehicle's driving status to determine whether to switch to defrosting mode or continue in cooling mode.

[0081] In one feasible implementation, the driving status of the vehicle containing the in-vehicle refrigerator can be re-determined after a preset cooling time has elapsed in cooling mode. Alternatively, the driving status of the vehicle containing the in-vehicle refrigerator can be determined periodically or in real-time after the in-vehicle refrigerator has entered cooling mode.

[0082] If the vehicle is in a stable driving state, it means that there is no risk or a low risk of the liquid medium in the evaporator of the car refrigerator overflowing. In order not to affect the subsequent cooling efficiency and cooling effect of the car refrigerator, it is necessary to defrost the car refrigerator to melt the solid medium into a liquid medium. Therefore, it is necessary to determine the target defrost cycle and / or target defrost heating time of the car refrigerator.

[0083] The target defrost cycle refers to the time interval between two defrost operations. Specifically, it refers to the time interval after the vehicle refrigerator has been running continuously for a period of time before automatically entering defrost mode to remove the frost accumulated on the condenser or evaporator. The target defrost heating time refers to the time required to complete one defrost operation. Specifically, it refers to the time required for the vehicle refrigerator to melt the frost on the condenser or evaporator through heating devices such as heaters or heating wires after entering defrost mode.

[0084] Step S120: Control the vehicle refrigerator to defrost according to the target defrost cycle and / or target defrost heating duration.

[0085] After determining the target defrost cycle, control the vehicle refrigerator to defrost according to the target defrost cycle. Alternatively, after determining the target defrost heating time, control the vehicle refrigerator to defrost according to the target defrost heating time. Or, after determining both the target defrost cycle and the target defrost heating time, control the vehicle refrigerator to defrost according to both.

[0086] In this embodiment of the application, if the vehicle is in a stable driving state, it means that there is no risk of the liquid medium in the evaporation dish of the vehicle refrigerator overflowing or the risk of overflowing is low. By determining the target defrosting cycle and / or target defrosting heating time of the vehicle refrigerator, the vehicle refrigerator is controlled to defrost according to the target defrosting cycle and / or target defrosting heating time, thereby improving the subsequent cooling efficiency and cooling effect of the vehicle refrigerator.

[0087] Reference Figure 3 In some embodiments of this application, determining the target defrost cycle for the vehicle-mounted refrigerator includes:

[0088] Step A111: Obtain the initial defrosting cycle of the vehicle refrigerator, the continuous running time of the vehicle, the first duration of the vehicle in a vibrating driving state, and the second duration of the vehicle in a stable driving state.

[0089] The initial frost cycle can be a value preset at the factory according to different models of vehicle refrigerators and stored in the memory; or it can be a value set by the user according to the actual situation during use and can be directly obtained.

[0090] The vehicle's continuous operating time is the total duration from engine start to the current moment. This continuous operating time includes the first duration of the vehicle in a vibrating driving state, the second duration of the vehicle in a stable operating state, and the sum of the durations in other states. It should be noted that these other states can include the vehicle's stationary waiting state. In this stationary waiting state, although the vehicle is not moving, the engine remains running; therefore, the time spent in this state is considered part of the vehicle's continuous operating time.

[0091] The first duration is the duration during which the vehicle is in a vibrating driving state, specifically the total duration from when the vehicle begins to enter the vibrating driving state to when it exits the vibrating driving state.

[0092] The second duration is the duration during which the vehicle is in a stable driving state, specifically the total time from when the vehicle begins to enter a stable driving state to when it exits the stable driving state.

[0093] The continuous running time, first duration and second duration of the vehicle can be collected by different timers. Each timer can send the collected continuous running time, first duration and second duration of the vehicle to the controller of the vehicle refrigerator for processing. At the same time, it can also send it to the display screen connected to the vehicle refrigerator, such as the vehicle terminal display screen, the display screen of the vehicle refrigerator itself, or the application installed on the user's mobile phone for display, so as to realize the data visualization effect.

[0094] Step A112: Determine the target defrosting cycle of the vehicle refrigerator based on the initial defrosting cycle, the vehicle's continuous running time, the first duration, and the second duration, wherein the target defrosting cycle is shorter than the initial defrosting cycle.

[0095] The target defrost cycle is the defrost cycle redefined after the vehicle transitions from a vibrating driving state to a stable driving state. The target defrost cycle differs from the initial defrost cycle; it is shorter. Normally, vehicle refrigerators defrost according to a fixed initial defrost cycle. When the vehicle is in a vibrating driving state, the refrigerator stops defrosting and enters cooling mode, causing a change in the initial defrost cycle. When the vehicle returns to a stable driving state, the defrost cycle needs to be redefined to improve defrosting efficiency and compensate for the time lost during the vibrating driving state. Due to the influence of vehicle vibration, the redefined target defrost cycle is shorter than the initial defrost cycle. After determining the target defrost cycle, the initial defrost cycle is updated using the redefined target defrost cycle, and the vehicle refrigerator is controlled to defrost according to the updated target defrost cycle. This allows for rapid defrosting within a shorter defrost cycle, improving the defrosting speed of the vehicle refrigerator.

[0096] In a feasible implementation, determining the target defrosting cycle of the vehicle refrigerator based on the initial defrosting cycle, the vehicle's continuous running time, the first duration, and the second duration includes: firstly, obtaining the sum of the first duration and the second duration; then, determining the ratio between this sum and the vehicle's continuous running time, which reflects the duration of the vehicle's vibration driving state and smooth driving state in the entire vehicle's operating state; after determining this ratio, multiplying the ratio by the initial defrosting cycle to obtain the multiplication result, thereby adjusting the initial defrosting cycle using this ratio, which reflects the degree of influence or relative importance of the vehicle's vibration driving state and smooth driving state on the vehicle's overall operating state; finally, subtracting the initial defrosting cycle from the multiplication result obtained above to obtain the target defrosting cycle of the vehicle refrigerator. Specifically, the target defrosting cycle of the vehicle refrigerator can be calculated using the following formula (1):

[0097] T1=T0-T0*((t1+t2) / t) formula (1);

[0098] Where T1 represents the target defrosting cycle, T0 represents the initial defrosting cycle, t1 represents the first duration, t2 represents the second duration, and t represents the continuous running time of the vehicle. It should be noted that (t1+t2) / t is less than 1.

[0099] In another feasible implementation, since vehicle acceleration / deceleration, vehicle ascent / descent, and vehicle travel on rough roads are all categorized as vehicle vibration driving states, the duration of the vehicle vibration driving state includes the sum of the duration of vehicle acceleration / deceleration, vehicle ascent / descent, and vehicle travel on rough roads. Since vehicle acceleration / deceleration, vehicle ascent / descent, and vehicle travel on rough roads may be discontinuous, it is necessary to separately obtain the duration t11 of vehicle acceleration / deceleration, the duration t12 of vehicle ascent / descent, and the duration t13 of vehicle travel on rough roads, and then add the obtained durations of each part to obtain the first duration t1. Therefore, in the above formula (1), t1 = t11 + t12 + t13.

[0100] It should be noted that in this case, the target defrosting heating time can be the initial defrosting heating time.

[0101] In this embodiment, the target defrost cycle of the vehicle refrigerator is re-determined based on the initial defrost cycle, the vehicle's continuous running time, the first duration, and the second duration. This ensures that the determined target defrost cycle takes into account the effects of both vibrating and stable driving conditions, making the determined target defrost cycle more accurate. Furthermore, controlling the vehicle refrigerator to defrost according to the updated target defrost cycle enables rapid defrosting within a shorter cycle, thus improving the defrosting speed of the vehicle refrigerator.

[0102] Reference Figure 4 In some embodiments of this application, determining the target defrost cycle and target defrost heating duration for the vehicle-mounted refrigerator includes:

[0103] Step B111: Obtain the initial defrosting heating duration of the vehicle refrigerator, the continuous running duration of the vehicle, the first duration of the vehicle in a vibrating driving state, and the second duration of the vehicle in a stable driving state.

[0104] The initial defrost heating time can be a value preset at the factory according to different models of car refrigerators and stored in the memory; or it can be a value set by the user according to the actual situation during use and can be directly obtained.

[0105] The methods for obtaining the vehicle's continuous running time, the first duration of the vehicle in a vibrating driving state, and the second duration of the vehicle in a stable driving state can refer to the above embodiments, and are the same as those in the above embodiments, so they will not be repeated here.

[0106] Step B112: Determine the target defrosting heating time based on the initial defrosting heating time, the vehicle's continuous running time, the first duration, and the second duration, wherein the target defrosting heating time is longer than the initial defrosting heating time.

[0107] The target defrosting heating time is the redefined defrosting heating time after the vehicle transitions from a vibrating driving state to a stable driving state. The target defrosting heating time differs from the initial defrosting heating time; it is longer. Normally, the vehicle refrigerator defrosts according to a fixed initial defrosting heating time. When the vehicle is in a vibrating driving state, the refrigerator stops defrosting and enters cooling mode, causing the initial defrosting heating time to change. When the vehicle returns to a stable driving state, the defrosting heating time needs to be redefined. Due to the influence of the vehicle's vibrating driving state, the redefined target defrosting heating time is longer than the initial defrosting heating time. After determining the target defrosting heating time, the initial defrosting heating time is updated using the redefined target defrosting heating time, and the vehicle refrigerator is controlled to defrost according to the updated target defrosting heating time. This ensures that the frost inside the vehicle refrigerator melts completely, improving the defrosting effect.

[0108] In a feasible implementation, determining the target defrosting heating time based on the initial defrosting heating time, the vehicle's continuous running time, the first continuous time, and the second continuous time includes: firstly, obtaining the sum of the first continuous time and the second continuous time; then, determining the ratio between the sum and the vehicle's continuous running time, which reflects the duration of the vehicle's vibration driving state and smooth driving state in the entire vehicle's operating state; after determining the ratio, multiplying the ratio by the initial defrosting heating time to obtain the multiplication result, thereby adjusting the initial defrosting heating time using the ratio, which reflects the degree of influence or relative importance of the vehicle's vibration driving state and smooth driving state on the vehicle's overall operating state; finally, adding the initial defrosting heating time to the multiplication result obtained above to obtain the target defrosting heating time of the vehicle refrigerator. Specifically, the target defrosting heating time of the vehicle refrigerator can be calculated using the following formula (2):

[0109] K1=K0+K0*((t1+t2) / t) formula (2);

[0110] Wherein, K1 represents the defrosting heating time, K0 represents the initial defrosting cycle, t1 represents the first duration, t2 represents the second duration, and t represents the continuous running time of the vehicle. It should be noted that (t1+t2) / t is less than 1.

[0111] In another feasible implementation, since vehicle acceleration / deceleration, vehicle ascent / descent, and vehicle travel on rough roads are all categorized as vehicle vibration driving states, the duration of the vehicle vibration driving state includes the sum of the duration of vehicle acceleration / deceleration, vehicle ascent / descent, and vehicle travel on rough roads. Since vehicle acceleration / deceleration, vehicle ascent / descent, and vehicle travel on rough roads may be discontinuous, it is necessary to separately obtain the duration t11 of vehicle acceleration / deceleration, the duration t12 of vehicle ascent / descent, and the duration t13 of vehicle travel on rough roads, and then add the obtained durations of each part together to obtain the first duration t1. Therefore, in the above formula (2), t1 = t11 + t12 + t13.

[0112] Step B113: Determine the initial defrost cycle of the vehicle refrigerator as the target defrost cycle.

[0113] While increasing the defrosting heating time, the initial defrosting cycle can be used as the target defrosting cycle, and defrosting can be performed according to the initial defrosting cycle and the updated target defrosting heating time.

[0114] In other embodiments, while increasing the defrosting heating time, the defrosting cycle can also be shortened, which not only improves defrosting efficiency but also enhances defrosting effect.

[0115] In this embodiment, the target defrosting heating time of the vehicle refrigerator is re-determined based on the initial defrosting cycle, the vehicle's continuous running time, the first duration, and the second duration. This ensures that the determined target defrosting heating time takes into account the effects of both vibrating and stable driving conditions, making the determined target defrosting heating time more accurate. Furthermore, controlling the vehicle refrigerator to defrost according to the updated target defrosting heating time and the initial defrosting cycle ensures that the frost inside the vehicle refrigerator melts completely, improving the defrosting effect.

[0116] In some embodiments of this application, if the vehicle is in a stable driving state, determining the target defrost cycle and / or target defrost heating duration for the vehicle refrigerator includes:

[0117] Step C111: If the vehicle remains in a stable driving state within the preset defrosting time, the initial defrosting cycle is determined to be the target defrosting cycle of the vehicle refrigerator, and / or the initial defrosting heating time is determined to be the target defrosting cycle of the vehicle refrigerator.

[0118] The preset defrosting time refers to the duration for the car refrigerator to defrost after the vehicle is in a stable driving state. This preset defrosting time can be determined based on the target defrosting cycle. For example, it can be the sum of two target defrosting cycles. That is, when the vehicle is in a stable driving state for two consecutive target defrosting cycles, the initial defrosting cycle is determined as the target defrosting cycle of the car refrigerator, and / or the initial defrosting heating time is determined as the target defrosting cycle of the car refrigerator. This allows the car refrigerator to resume defrosting at the initial defrosting cycle and initial defrosting heating time. The initial defrosting cycle and initial defrosting heating time can maintain a stable internal temperature of the car refrigerator, thereby providing a better user experience.

[0119] It should be noted that if the vehicle remains in a stable driving state within the preset defrost time, the vehicle refrigerator can defrost according to the shortened target defrost cycle and / or the increased defrost heating time during this period. If the vehicle remains in a stable driving state within the preset defrost time, the initial defrost cycle is then determined as the target defrost cycle for the vehicle refrigerator, and / or the initial defrost heating time is determined as the target defrost cycle for the vehicle refrigerator, and the vehicle refrigerator is controlled to defrost according to the initial defrost cycle and / or the initial defrost heating time.

[0120] In this embodiment, if the vehicle is continuously in a stable driving state within the preset defrosting time, the initial defrosting cycle is determined as the target defrosting cycle of the vehicle refrigerator, and / or the initial defrosting heating time is determined as the target defrosting cycle of the vehicle refrigerator. This allows the vehicle refrigerator to maintain a stable internal temperature when defrosting according to the initial defrosting cycle and / or the initial defrosting heating time, thereby providing a better user experience.

[0121] Reference Figure 5 In some embodiments of this application, the defrosting method for a vehicle-mounted refrigerator further includes:

[0122] Step S210: Obtain the height of the liquid medium in the evaporation dish of the vehicle refrigerator.

[0123] An evaporating dish can be placed below the evaporator of a car refrigerator to collect the liquid medium dripping from the melted frost on the evaporator during defrost mode.

[0124] The liquid medium can be defrosting water.

[0125] The liquid medium height refers to the height of the defrosting water in the evaporating dish.

[0126] In one feasible implementation, a sensor for detecting height information can be installed at a preset height inside the evaporating dish. This sensor, for example, can be an infrared sensor, which detects the height of the liquid medium inside the evaporating dish of the car refrigerator. The principle of the infrared sensor measuring the height of the liquid medium is mainly based on the reflection and absorption characteristics of infrared light. When infrared light shines on the liquid medium, some of the infrared light is reflected back by the liquid medium, while the rest is absorbed. By measuring the intensity and time difference of the reflected infrared light, or by detecting changes in the refraction and reception intensity of the light, it is possible to calculate whether the height of the liquid medium has reached the preset height. The preset height can be set to 85% of the height of the evaporating dish.

[0127] Specifically, an infrared sensor is fixed at a preset height position on the evaporating dish, ensuring it accurately points towards the interior of the container. The sensor's installation position should be determined based on the container's dimensions and measurement requirements. After installation, the infrared sensor is calibrated to ensure accurate measurement of the liquid medium's height. The calibration process may include adjusting the sensor's sensitivity and setting a reference distance. When the liquid medium rises and contacts the sensor, it reflects infrared signals, which the sensor receives. If the liquid medium's height has not reached the preset height, the sensor may receive a reflected signal from the container wall or other objects, or the light may be directly refracted back to the receiver, resulting in a high reception intensity, or no reflected signal at all. The sensor converts the received signal into an electrical signal, which is then amplified and processed by circuitry. The processed signal can be converted into a digital signal for recording, storage, and display. Based on the processed signal, it can be determined whether the liquid medium's height has reached the preset height. If the sensor receives a strong reflected signal or a strong refracted light signal, it indicates that the liquid medium's height has not reached the preset height; if it receives a weak reflected signal or a weakened refracted light signal, it indicates that the liquid medium's height is close to or has reached the preset height.

[0128] In another feasible implementation, the principle of water pressure change can be utilized to measure the height of the liquid medium using a pressure sensor.

[0129] In another feasible implementation, the principle of ultrasonic reflection can be used to measure the distance between the surface of the liquid medium and the sensor, thereby calculating the height of the liquid medium.

[0130] If the liquid medium level is lower than the set value, execute step S10 to obtain the working mode of the vehicle refrigerator; step S20, if the vehicle refrigerator is in defrost mode, determine the driving status of the vehicle where the vehicle refrigerator is located; and step S30, if the vehicle is in a vibrating driving state, control the vehicle refrigerator to switch from defrost mode to cooling mode.

[0131] If the liquid level is below the set value, the operating mode of the vehicle refrigerator is further determined. If the vehicle refrigerator is in defrost mode, it indicates that the liquid level in the evaporator is rising. At this point, the driving status of the vehicle needs to be further determined. If the vehicle is driving smoothly, defrosting can proceed according to the normal defrosting procedure, and there is no risk of liquid overflow from the evaporator. If the vehicle is vibrating, there is a risk of liquid overflow from the evaporator. In this case, defrosting needs to be stopped and the system switched to cooling mode to avoid adding more liquid and to reduce the existing liquid level in the evaporator, thereby reducing the risk of liquid overflow, until the liquid level in the evaporator is below the set value.

[0132] Alternatively, if the liquid medium height is higher than or equal to the set value, execute step S10 to obtain the working mode of the vehicle refrigerator; and in step S220, if the vehicle refrigerator is in defrosting mode, control the vehicle refrigerator to switch from defrosting mode to cooling mode.

[0133] If the liquid level is higher than or equal to the set value, the operating mode of the vehicle refrigerator is further determined. If the vehicle refrigerator is in defrost mode, it means that the liquid level in the evaporator is increasing. At this time, regardless of whether the vehicle is driving smoothly or vibrating, there is a risk of the liquid level in the evaporator overflowing. In this case, defrosting should be stopped and the refrigerator switched to cooling mode to avoid adding more liquid and to reduce the existing liquid level in the evaporator, thus reducing the risk of overflow, until the liquid level in the evaporator is lower than the set value.

[0134] In this embodiment, the liquid medium level in the evaporation dish of the vehicle refrigerator is obtained; if the liquid medium level is lower than a set value, the operating mode of the vehicle refrigerator is obtained; if the vehicle refrigerator is in defrost mode, the driving status of the vehicle where the vehicle refrigerator is located is determined; if the vehicle is in a vibrating driving state, the vehicle refrigerator is controlled to switch from defrost mode to cooling mode; or, if the liquid medium level is higher than or equal to a set value, the operating mode of the vehicle refrigerator is obtained; if the vehicle refrigerator is in defrost mode, the vehicle refrigerator is controlled to switch from defrost mode to cooling mode; this reduces the risk of liquid medium overflow in the evaporation dish under different scenarios.

[0135] Reference Figure 6 Based on the above embodiments, in some embodiments of this application, if the vehicle refrigerator is in defrost mode, after controlling the vehicle refrigerator to switch from defrost mode to cooling mode, the method further includes:

[0136] Step S230: After preset cooling time, obtain the height of the solid medium in the evaporation dish.

[0137] Since refrigeration causes the liquid medium in the evaporating dish to transform into a solid medium, the height of the solid medium in the evaporating dish is obtained after the car refrigerator switches to refrigeration mode and has undergone a preset refrigeration period. The method for obtaining the height of the solid medium in the evaporating dish is similar to that for obtaining the height of the liquid medium; please refer to the method for obtaining the height of the liquid medium for details, which will not be repeated here.

[0138] Step S240: If the solid medium height is higher than or equal to the set value, control the vehicle refrigerator to switch the cooling mode to the defrosting mode.

[0139] If the solid medium height is higher than or equal to the set value, it indicates that, within a certain design margin, some large ice crystals are blocking the height detection sensor. In this case, defrosting heating is activated until the solid medium height falls below the set value, at which point normal cooling mode operation resumes. This method avoids the problem of ice buildup inside the car refrigerator hindering cold air circulation and reducing cooling efficiency when the refrigerator is in cooling mode for extended periods.

[0140] Alternatively, in step S250, if the solid medium height is lower than the set value, control the vehicle refrigerator to maintain the cooling mode.

[0141] If the solid medium height is lower than the set value, it means that the vehicle refrigerator can continue to maintain the cooling mode, so the vehicle refrigerator will continue to cool to meet the cooling demand.

[0142] In this embodiment, the height of the solid medium inside the evaporation dish is measured. If the solid medium height is higher than or equal to a set value, the vehicle refrigerator is controlled to switch to defrost mode. If the solid medium height is lower than the set value, the vehicle refrigerator is controlled to maintain the defrost mode. This control method not only meets the cooling needs of the vehicle refrigerator but also avoids the problem of ice buildup inside the vehicle refrigerator hindering the circulation of cold air and reducing cooling efficiency when the refrigerator is in defrost mode for a long time, thus improving cooling efficiency and cooling effect.

[0143] Reference Figure 7 In some embodiments of this application, determining the driving status of the vehicle where the in-vehicle refrigerator is located includes:

[0144] Step S21: Obtain the vehicle's tilt angle and acceleration.

[0145] The tilt angle of the vehicle is collected by a tilt sensor installed on the vehicle, and the acceleration of the vehicle is collected by an acceleration sensor installed on the vehicle. The collected tilt angle and acceleration are analyzed to obtain the driving status of the vehicle where the car refrigerator is located.

[0146] A tilt sensor is a sensor used to measure the tilt angle of a vehicle. It uses technologies such as gyroscopes or accelerometers to monitor the vehicle's tilt angle in real time, whether the vehicle is moving or stationary. When a vehicle is traveling on rough roads or engaging in off-road activities—that is, when the vehicle is in a vibrating driving state—the tilt sensor helps the driver or vehicle control system understand the vehicle's current state, thereby improving the vehicle's driving stability and safety.

[0147] Accelerometers are used to measure changes in a vehicle's acceleration. They are typically used in conjunction with tilt sensors to detect changes in acceleration in various directions, reflecting the vehicle's vibration and tilt. Accelerometers provide real-time acceleration data, helping vehicle control systems determine the vehicle's dynamic state and take appropriate measures to maintain stability.

[0148] It should be noted that the vehicle's tilt angle and acceleration can be considered as the tilt angle and acceleration of the evaporator of the car refrigerator. By determining the vehicle's tilt angle and acceleration, the tilt angle and acceleration of the evaporator of the car refrigerator can be reflected, which facilitates subsequent assessment of whether there is a risk of spillage of the liquid medium in the evaporator.

[0149] Step S22: Determine the vehicle's driving state based on the tilt angle and acceleration.

[0150] The vehicle's driving status includes either vibrating driving status or smooth driving status.

[0151] In one feasible implementation, a mapping relationship between different tilt angles and accelerations and the vehicle's driving state can be pre-established, and the vehicle's driving state can be determined through this mapping relationship and the current vehicle tilt angle and acceleration.

[0152] In another feasible implementation, if the tilt angle is greater than or equal to a preset angle and the acceleration is greater than or equal to a preset acceleration, the vehicle is determined to be in a vibrating driving state; if the tilt angle is less than a preset angle and the acceleration is less than a preset acceleration, the vehicle is determined to be in a stable driving state.

[0153] In another feasible implementation, if the tilt angle is greater than or equal to a preset angle and the acceleration is greater than or equal to a preset acceleration for a first duration greater than a first preset duration, the vehicle is determined to be in a vibrating driving state; if the tilt angle is less than a preset angle and the acceleration is less than a preset acceleration for a second duration greater than a second preset duration, the vehicle is determined to be in a stable driving state. By determining that the vehicle is in a vibrating driving state when the first duration is greater than the first preset duration, and determining that the vehicle is in a stable driving state when the second duration is greater than the second preset duration, misjudgment of the vehicle's driving state can be avoided, and the accuracy of the vehicle's driving state judgment can be improved.

[0154] The preset angle, preset acceleration, first preset duration, and second preset duration mentioned above can be set according to actual conditions.

[0155] In this embodiment, the vehicle's tilt angle and acceleration are obtained; based on the tilt angle and acceleration, the vehicle's driving state is determined, thereby improving the accuracy of the vehicle's driving state judgment.

[0156] In other embodiments, determining the driving status of the vehicle containing the in-vehicle refrigerator includes analyzing images acquired by image sensors installed on the vehicle to obtain the driving status of the vehicle. During image analysis and processing, a pre-trained large language model combined with corresponding prompt text can be used to analyze and process the images, thereby improving the processing efficiency of the vehicle's driving status and enabling rapid determination of the vehicle's driving status. Other methods can also be used to determine the driving status of the vehicle containing the in-vehicle refrigerator.
