[0001] This application relates to the field of refrigerator technology, and in particular to a control system, method and storage medium for a fruit and vegetable preservation refrigerator. Background Technology

[0002] Refrigerators, as a common household food storage device, extend the shelf life of fruits and vegetables through a low-temperature environment. As consumers increasingly demand higher quality food, light-based preservation technology is gradually being applied to the refrigerator industry. This technology uses specific wavelengths of light to slow down nutrient loss in fruits and vegetables, inhibit bacterial growth, and improve preservation.

[0003] In existing technologies, some fruit and vegetable preservation refrigerators are equipped with a lighting module. Fixed lighting parameters are pre-stored in a storage module, and the controller controls the operation of the lighting module according to a preset program to provide basic preservation lighting for the fruits and vegetables in the preservation compartment. For example, the controller calls up a single lighting parameter and runs it continuously based on the type of fruit and vegetable selected by the user or the default settings.

[0004] However, in existing technologies, the light parameters are fixed and cannot be dynamically adjusted according to the actual storage time of fruits and vegetables in the preservation compartment. Fruits and vegetables have different physiological states and preservation requirements at different stages of storage, and fixed light parameters are difficult to adapt to the specific requirements of each stage, resulting in decreased preservation effect and accelerated nutrient loss in the later stages of storage. In addition, existing solutions cannot customize light parameters according to users' personalized needs, making it difficult to meet the preservation requirements of different fruits and vegetables or special varieties. Summary of the Invention

[0020] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0021] In the field of fruit and vegetable preservation and storage, existing refrigerator control systems often suffer from a lack of targeted lighting control and an inability to dynamically adjust according to the storage stage. These systems typically provide only fixed lighting parameters; the controller cannot adjust its operation based on the storage duration and actual needs of the fruits and vegetables, and the operating parameters of the lighting module cannot be precisely matched to the storage stage. When users place fruits and vegetables into the refrigerator's crisper compartment, existing systems cannot determine their storage stage based on the storage duration, nor can they access the corresponding lighting parameters. This results in a mismatch between the lighting module's operation and the preservation needs of the fruits and vegetables—either excessive light intensity leading to energy waste or insufficient light to meet preservation requirements. Consequently, the preservation effect is affected, hindering long-term, high-quality preservation and storage. This also increases user inconvenience and fails to meet users' demands for long-term freshness of fruits and vegetables.

[0022] To solve the above problems, see [link to relevant documentation]. Figure 1 This application provides a control system for a fruit and vegetable preservation refrigerator, including: a preservation compartment 10, a light module 20, a storage module 30, and a controller 40.

[0023] The freshness compartment 10 is located inside the refrigerator. The freshness compartment 10 is a dedicated space inside the refrigerator for storing fruits and vegetables. The freshness compartment 10 usually adopts a drawer-type structure or an independent compartment structure, which can provide a stable and airtight storage environment for fruits and vegetables, and prevent external environmental interference with the preservation of fruits and vegetables.

[0024] The light module 20 is located at the top center of the preservation compartment 10. This installation position allows the light emitted by the light module 20 to evenly cover the entire interior of the preservation compartment 10, ensuring that all fruits and vegetables in the preservation compartment 10 can receive uniform preservation light.

[0025] Specifically, the light module 20 is configured to provide light for preserving fruits and vegetables in the preservation compartment 10.

[0026] The illumination module 20 can be implemented in various ways. For example, the illumination module 20 can be multiple light-emitting diode (LED) light sources installed in a preset array layout on the top area of ​​the preservation compartment 10. LED light sources have the characteristics of low energy consumption and stable illumination, providing long-term, stable illumination for fruit and vegetables. Alternatively, the illumination module 20 can be an adjustable light source component, containing multiple light source units with different light qualities. Each light quality light source unit can independently adjust its operating state according to received control commands, adapting to the illumination requirements of different storage stages. By continuously providing appropriate illumination, the illumination module 20 delays wilting and nutrient loss in fruits and vegetables, improving their preservation effect.

[0027] Storage module 30 is configured to: pre-store a set of fruit and vegetable light operation parameters.

[0028] The fruit and vegetable lighting operation parameter set is a data set pre-stored in the storage module 30. This set stores lighting operation parameters corresponding to at least one type of fruit and vegetable, covering the preservation lighting requirements of common fruits and vegetables. The lighting operation parameters for each type of fruit and vegetable include the lighting parameters corresponding to that fruit and vegetable at multiple storage stages.

[0029] The controller 40 is electrically connected to the light module 20 and the storage module 30. The controller 40 reads the set of fruit and vegetable light operation parameters stored in the storage module 30 and determines the light parameters that should be used at the moment based on the real-time information on the type of fruit and vegetables and the storage time. The controller 40 generates control commands based on the determined light parameters and sends the control commands to the light module 20 to control the operating status of the light module 20.

[0030] Controller 40 is configured as follows: Obtain the types of fruits and vegetables inside the refrigeration compartment 10; Based on the type of fruit and vegetable, the corresponding light operation parameters for that type of fruit and vegetable are retrieved from the set of light operation parameters for fruit and vegetable; The current storage stage is determined based on the storage time of fruits and vegetables in the preservation compartment 10; Based on the illumination parameters corresponding to the current storage stage, control the operation of the illumination module 20.

[0031] Specifically, based on the types of fruits and vegetables in the preservation compartment 10, the controller 40 retrieves the corresponding lighting parameters for that type of fruit or vegetable from the fruit and vegetable lighting parameter set in the storage module 30. These retrieved lighting parameters include the lighting parameters corresponding to that type of fruit or vegetable at multiple storage stages, covering the lighting requirements throughout the entire storage cycle. The controller 40 determines the current storage stage based on the storage time of the fruits and vegetables in the preservation compartment 10, thus identifying the preservation stage of the fruit or vegetable. Once the current storage stage is determined, the controller 40 extracts the lighting parameters corresponding to that current storage stage from the retrieved lighting parameters. The controller 40 generates corresponding control commands based on the extracted lighting parameters, and these control commands are transmitted to the lighting module 20. After receiving the control command, the illumination module 20 operates according to the operating mode indicated by the control command. As the storage time continues to increase, the controller 40 will redetermine the current storage stage based on the updated storage time. When the change in storage time causes the current storage stage to change, the controller 40 will extract the illumination parameters corresponding to the new stage from the previously called illumination operation parameters, and generate a new control command based on the new illumination parameters and send it to the illumination module 20. The illumination module 20 then switches to the operating mode corresponding to the new storage stage.

[0032] As can be seen from the above technical solution, this embodiment obtains the types of fruits and vegetables in the preservation compartment 10 through the controller 40, and calls up complete lighting operation parameters containing lighting parameters for multiple storage stages from the fruit and vegetable lighting operation parameters collection of the storage module 30 based on the types of fruits and vegetables. Then, it determines the current storage stage based on the storage time of the fruits and vegetables in the preservation compartment 10, and extracts the corresponding lighting parameters from the called lighting operation parameters according to the determined current storage stage to control the operation of the lighting module 20. This embodiment solves the problem in the prior art that the lighting parameters are fixed and cannot be dynamically adjusted according to the storage time of fruits and vegetables, ensuring that the lighting output by the lighting module 20 always adapts to the needs of different storage stages of fruits and vegetables, and improving the preservation effect of fruits and vegetables.

[0033] In some embodiments, see Figure 1 The control system of the fruit and vegetable preservation refrigerator provided in this application also includes a detection module 50. The detection module 50 is electrically connected to the controller 40. The detection module 50 is used to detect whether fruits and vegetables are placed in the preservation compartment 10, and at the same time, it is used to collect image information of the fruits and vegetables in the preservation compartment 10, providing data support for the controller 40 to obtain the types of fruits and vegetables. The detection module 50 is set in the top middle part of the preservation compartment 10. This installation position allows the detection module 50 to clearly capture images of fruits and vegetables in the preservation compartment 10, and at the same time, it can quickly detect whether fruits and vegetables are placed in the preservation compartment 10, ensuring that the detection signal of the detection module 50 is timely and accurate.

[0034] The detection module 50 can be implemented in various ways. For example, the detection module 50 can be a camera component integrating image acquisition and object detection functions. The camera component can capture images of the inside of the preservation compartment 10 in real time, capturing image information of fruits and vegetables, and can detect whether fruits and vegetables have been placed in the preservation compartment 10 by changes in the image. Alternatively, the detection module 50 can be a combination of an image sensor and an infrared detection sensor. The infrared detection sensor is used to detect whether an object has been placed in the preservation compartment 10, and the image sensor is used to acquire image information of the object after it has been detected, ensuring that the detection module 50 can stably complete the detection and image acquisition work. This embodiment does not limit the implementation method of the detection module 50.

[0035] The controller 40 is configured to retrieve the types of fruits and vegetables inside the preservation compartment 10. In response to the detection module 50 detecting that fruits and vegetables have been placed in the preservation compartment 10, the detection module 50 acquires the image information of the fruits and vegetables collected by the detection module 50. Based on image information, the types of fruits and vegetables can be identified.

[0036] Specifically, the detection module 50 monitors the state inside the fresh-keeping compartment 10 in real time. When a user places fruits and vegetables into the fresh-keeping compartment 10, the detection module 50 detects the presence of these items and collects image information of the fruits and vegetables inside. The detection module 50 transmits the collected image information to the controller 40, which receives the image information. The controller 40 processes the received image information, extracting features such as shape and color using image recognition technology. Combined with the pre-stored fruit and vegetable type feature information in the storage module 30, the controller identifies the types of fruits and vegetables inside the fresh-keeping compartment 10. This embodiment achieves automatic acquisition of fruit and vegetable types by adding a detection module 50 to the control system of the fruit and vegetable fresh-keeping refrigerator.

[0037] In some embodiments, see Figure 1 The control system of the fruit and vegetable preservation refrigerator provided in this application also includes an interactive module 60, which is electrically connected to the controller 40. The interactive module 60 is located on the outside of the refrigerator door or on the refrigerator's control panel. This installation location is convenient for users to operate, and users can input relevant information at any time through the interactive module 60 without opening the refrigerator door, thus not affecting the storage environment inside the preservation compartment 10.

[0038] The interactive module 60 can be implemented in several ways. For example, the interactive module 60 can be a touch-screen control panel, which is convenient to operate and has a clear display. Users can input information about the types of fruits and vegetables and the corresponding lighting parameters through touch operation. Alternatively, the interactive module 60 can be a combination of a button-type control panel and a display screen. The button-type control panel is used for user input, and the display screen is used to display the user's input and the system's operating status, ensuring that the user can accurately input the required information.

[0039] The controller 40 is also configured to: receive fruit and vegetable type information and corresponding light operation parameters input by the user through the interaction module 60; and associate and store the received fruit and vegetable type information and corresponding light operation parameters in the storage module 30 to update or supplement the fruit and vegetable light operation parameter set.

[0040] Specifically, when a user encounters a type of fruit or vegetable that the detection module 50 cannot recognize, or when a user needs to customize the lighting parameters for a certain type of fruit or vegetable, the user can input the fruit or vegetable type information through the interaction module 60, along with the corresponding lighting parameters. These lighting parameters include the lighting parameters corresponding to the fruit or vegetable at multiple storage stages. The interaction module 60 synchronously transmits the user-inputted fruit or vegetable type information and the corresponding lighting parameters to the controller 40. The controller 40 receives the fruit or vegetable type information and the corresponding lighting parameters input by the user through the interaction module 60. The controller 40 performs association processing on the received fruit or vegetable type information and the corresponding lighting parameters, establishing a one-to-one correspondence between the fruit or vegetable type information and the corresponding lighting parameters to avoid parameter errors. Afterward, the controller 40 stores the associated fruit or vegetable type information and lighting parameters in the storage module 30, enabling updates or supplements to the fruit or vegetable lighting parameter set within the storage module 30.

[0041] This embodiment solves the problem in the prior art that the set of fruit and vegetable lighting operation parameters cannot be flexibly updated and cannot adapt to users' personalized needs. Through the cooperation of the interaction module 60, the controller 40, and the storage module 30, users can supplement or update the lighting operation parameters according to actual needs, which expands the system's adaptability and ensures that the controller 40 can call up more comprehensive and user-friendly lighting operation parameters, providing more accurate data support for subsequent control of the lighting module 20 and improvement of fruit and vegetable preservation.

[0042] In some embodiments, see Figure 1 The controller 40 is configured to obtain the types of fruits and vegetables in the preservation compartment 10 based on the information on the types of fruits and vegetables entered by the user through the interaction module 60.

[0043] Specifically, after a user places fruits and vegetables into the preservation compartment 10, the user can input the type of fruit and vegetables through the interaction module 60. The interaction module 60 transmits the input type of fruit and vegetables to the controller 40. Based on the type of fruit and vegetables input by the user through the interaction module 60, the controller 40 uses this information as the obtained type of fruit and vegetables in the preservation compartment 10 for subsequent use in calling up lighting operation parameters and determining the current storage stage. After the user inputs the type of fruit and vegetables through the interaction module 60, the controller 40, based on this type of fruit and vegetables information, calls up the corresponding lighting operation parameters from the fruit and vegetables lighting operation parameter set in the storage module 30, determines the current storage stage based on the storage duration, and controls the operation of the lighting module 20.

[0044] This embodiment, through the cooperation of the interaction module 60 and the controller 40, provides users with a way to obtain fruit and vegetable types based on user input. This solves the problem that users cannot obtain type information when the detection module 50 cannot identify certain fruit and vegetable types. It ensures that the controller 40 can obtain the types of fruits and vegetables in the preservation compartment 10 under any circumstances, thereby improving the applicability of the system and the user experience.

[0045] In some embodiments, see Figure 1 The control system of the fruit and vegetable preservation refrigerator provided in this application also includes a timing module 70, which is electrically connected to the controller 40. The timing module 70 is set on the circuit board of the controller 40 or installed as an independent module inside the refrigerator. The timing module 70 is used to accurately record the storage time of fruits and vegetables in the preservation compartment 10, providing time data support for the controller 40 to determine the current storage stage.

[0046] There are several ways to implement the timing module 70. For example, the timing module 70 can be a timer circuit integrated inside the controller 40, which has the characteristics of fast response and does not occupy extra space. Alternatively, the timing module 70 can be an independent real-time clock chip, which can continuously keep time and retain time data even after power failure, ensuring accurate and reliable timing.

[0047] The controller 40 is also configured to: in response to the detection module 50 detecting that fruits and vegetables are placed in the preservation compartment 10, control the timing module 70 to start timing and record the storage time of the fruits and vegetables in the preservation compartment 10.

[0048] Specifically, when a user places fruits and vegetables into the preservation compartment 10, the detection module 50 detects the placement and sends a placement signal to the controller 40. In response to the detection module 50's detection, the controller 40 sends a start command to the timing module 70, instructing the timing module 70 to begin timing. Upon receiving the start command from the controller 40, the timing module 70 begins timing and continuously records the storage time of the fruits and vegetables within the preservation compartment 10. The timing module 70 stores the real-time recorded storage time data in an internal register, which the controller 40 can read at any time for subsequent determination of the current storage stage.

[0049] This embodiment provides the controller 40 with accurate storage duration data through the setting of the timing module 70, which solves the problem that the controller 40 cannot obtain the storage duration of fruits and vegetables and cannot determine the storage stage. This ensures that the controller 40 can determine the current storage stage based on accurate duration data, laying the foundation for light control adapted to subsequent stages.

[0050] In some embodiments, see Figure 1The control system for the fruit and vegetable preservation refrigerator provided in this application includes at least a first storage stage, a second storage stage, and a third storage stage. The first, second, and third storage stages correspond to different periods in the fruit and vegetable preservation process, and each stage has different preservation requirements and light requirements.

[0051] Controller 40 determines the current storage stage based on the storage time of fruits and vegetables in the preservation compartment 10, specifically configured as follows: The storage time of fruits and vegetables in the preservation compartment 10 is recorded by the timing module 70. When the storage duration is less than or equal to the first preset duration, the current storage stage is determined as the first storage stage; When the storage duration is greater than the first preset duration and less than or equal to the second preset duration, the current storage stage is determined to be the second storage stage; When the storage duration exceeds the second preset duration, the current storage stage is determined to be the third storage stage.

[0052] Specifically, the controller 40 acquires the storage time of fruits and vegetables in the preservation compartment 10, as recorded by the timing module 70. The timing module 70 continuously records the time from when the fruits and vegetables are placed in the preservation compartment 10 to the current moment. The storage module 30 pre-stores a first preset duration and a second preset duration, where the first preset duration is shorter than the second preset duration. The first preset duration can be set to 3 days, and the second preset duration can be set to 6 days.

[0053] When the storage period is less than or equal to 3 days, the controller 40 determines the current storage stage as the first storage stage. This situation corresponds to a storage period of 0 to 3 days, that is, the first three days after the fruits and vegetables are placed in the preservation chamber 10. At this time, the fruits and vegetables are in the initial stage of storage and need to be adapted to the preservation light of the first storage stage.

[0054] When the storage period is greater than 3 days and less than or equal to 6 days, the controller 40 determines that the current storage stage is the second storage stage. This situation corresponds to a storage period of 4 to 6 days, at which point the fruits and vegetables are in the middle of storage and need to be switched to the light parameters corresponding to the second storage stage.

[0055] When the storage period exceeds 6 days, the controller 40 determines that the current storage stage is the third storage stage. This situation corresponds to a storage period of more than 6 days, at which point the fruits and vegetables are in the later stage of storage and need to be adapted to the lighting scheme of the third storage stage.

[0056] This embodiment divides multiple storage stages into a first storage stage, a second storage stage, and a third storage stage, and sets a first preset duration and a second preset duration as stage switching thresholds. This provides the controller 40 with a clear basis for stage determination, ensuring that the controller 40 can accurately determine the current storage stage based on the storage duration, and providing accurate stage information for subsequent staged illumination control.

[0057] In some embodiments, see Figure 1 In the control system of the fruit and vegetable preservation refrigerator provided in this application, the illumination module 20 includes multiple adjustable light sources with different light qualities. Multiple adjustable light sources with different light qualities refer to the illumination module 20 containing multiple light source units capable of emitting light of different wavelengths, each with a different light quality. In this embodiment, the illumination module 20 specifically includes a red light source, a blue light source, and an ultraviolet light source. The red light source emits red-band light, the blue light source emits blue-band light, and the ultraviolet light source emits ultraviolet-band light. Each adjustable light source with different light qualities can independently adjust its operating state according to the control commands sent by the controller 40, including turning it on or off, adjusting the light intensity, and controlling the illumination time.

[0058] The illumination parameters include the illumination intensity and illumination time corresponding to each adjustable light source of each light quality. These illumination parameters are specific values ​​pre-stored in the storage module 30, used to define the operating mode of each light source in the illumination module 20. For example, for a red light source, the illumination parameters specify the illumination intensity value and duration of continuous illumination that it should output during the current storage phase; similarly, blue light sources and ultraviolet light sources have their own corresponding illumination intensities and illumination times.

[0059] Controller 40 executes the control of the lighting module based on the lighting parameters corresponding to the current storage stage, specifically configured as follows: When the current storage stage is the first storage stage, the operation of each adjustable light source is controlled based on the light intensity and light duration of each adjustable light source corresponding to the first storage stage. When the current storage stage is the second storage stage, the operation of each adjustable light source is controlled based on the light intensity and light duration of each adjustable light source corresponding to the second storage stage. When the current storage stage is the third storage stage, the operation of each adjustable light source is controlled based on the light intensity and light duration of each adjustable light source corresponding to the third storage stage.

[0060] Specifically, when the controller 40 determines that the current storage stage is the first storage stage, the controller 40 extracts the lighting parameters corresponding to the first storage stage from the previously called lighting operation parameters. The lighting parameters corresponding to the first storage stage include the light intensity and lighting time corresponding to the red light source, blue light source, and ultraviolet light source, respectively, in the first storage stage. Based on these light intensities and lighting times, the controller 40 sends control commands to the red light source, blue light source, and ultraviolet light source, respectively, to control each adjustable light source to operate according to its corresponding light intensity and lighting time.

[0061] When controller 40 determines that the current storage stage is the second storage stage, it extracts the corresponding lighting parameters for the second storage stage from the previously called lighting operation parameters. The lighting parameters for the second storage stage include the light intensity and illumination time for the red, blue, and ultraviolet light sources, respectively, under the second storage stage. These parameters may differ from those of the first storage stage. Based on the light intensity and illumination time of the second storage stage, controller 40 controls the red, blue, and ultraviolet light sources to switch to the new operating states.

[0062] When controller 40 determines that the current storage stage is the third storage stage, it extracts the corresponding lighting parameters for the third storage stage from the previously called lighting operation parameters. These lighting parameters include the light intensity and duration for the red, blue, and ultraviolet light sources, respectively, under the third storage stage. Based on these parameters, controller 40 controls the red, blue, and ultraviolet light sources to operate according to the requirements of the third storage stage.

[0063] The following is an example of a specific operation process. In one embodiment, a user places a group of mushrooms into the preservation compartment 10. The controller 40 obtains that the type of fruit and vegetable is mushrooms and retrieves the corresponding light operation parameters for the mushrooms from the storage module 30. Among the light operation parameters for the mushrooms, the first storage stage corresponds to the first 3 days after they are placed in the preservation compartment 10 (i.e., storage time from 0 to 3 days), the second storage stage corresponds to the 4th to 6th day, and the third storage stage corresponds to a storage time of more than 6 days.

[0064] During the first storage stage, the lighting parameters for the mushrooms are as follows: red and blue light sources operate simultaneously, while the ultraviolet light source operates intermittently. The light intensity of the red light source is 150 lux, the light intensity of the blue light source is 200 lux, and the light intensity of the ultraviolet light source is 50 lux. The illumination time for the red and blue light sources is 10 minutes per hour, and the illumination time for the ultraviolet light source is 10 minutes per day. Based on the lighting parameters for the first storage stage, the controller 40 controls the red light source to operate at a light intensity of 150 lux and an illumination time of 10 minutes per hour, controls the blue light source to operate at a light intensity of 200 lux and an illumination time of 10 minutes per hour, and controls the ultraviolet light source to operate at a light intensity of 50 lux and an illumination time of 10 minutes per day.

[0065] In the second storage stage, the light parameters for the mushrooms are adjusted as follows: the illumination time for red and blue light sources is reduced to 85% of the illumination time in the first storage stage, the illumination time for ultraviolet light source is extended by 25%, and the light intensity of each light source remains unchanged. Based on the light parameters of the second storage stage, controller 40 adjusts the illumination time of red and blue light sources to 8.5 minutes per hour and the illumination time of ultraviolet light source to 12.5 minutes per day.

[0066] In the third storage stage, the light parameters for the mushrooms are further adjusted as follows: the illumination time for red and blue light sources is reduced to 65% of the illumination time in the first storage stage, while the illumination time for ultraviolet light sources is extended by 50%. Based on the light parameters of the third storage stage, controller 40 controls the illumination time of red and blue light sources to 6.5 minutes per hour and the illumination time of ultraviolet light sources to 15 minutes per day.

[0067] In another embodiment, a user places a thumb-sized watermelon into the preservation compartment 10. Since there is no thumb-sized watermelon sample information in the fruit and vegetable database, the user activates the custom mode through the interaction module 60 and enters the corresponding lighting operation parameters for the thumb-sized watermelon. The lighting operation parameters set by the user are: alternating operation of blue light source and ultraviolet light source, no operation of red light source, light intensity of blue light source of 300 lux, light intensity of ultraviolet light source of 70 lux, light duration of blue light source of 5 minutes per hour, light duration of ultraviolet light source of 5 minutes per hour, with no overlap between the two. The controller 40 receives these lighting operation parameters input by the user and associates the fruit and vegetable type information of the thumb-sized watermelon with the lighting operation parameters and stores them in the storage module 30. When the user puts in a thumb-sized watermelon again, the controller 40 retrieves the corresponding lighting operation parameters from the storage module 30 based on the fruit and vegetable type and controls the operation of the lighting module 20 according to the above-described phased control logic.

[0068] This embodiment uses three adjustable light sources of different light qualities—red, blue, and ultraviolet—and refines the lighting parameters to the light intensity and duration corresponding to each light quality. This allows the controller 40 to independently control each light source, achieving more precise lighting management. Different combinations of light intensity and duration are used at different storage stages, accurately adapting to the physiological needs of fruits and vegetables at each stage and further improving preservation. The specific embodiments for mushrooms and watermelons in the technical disclosure verify the feasibility and effectiveness of the technical solution presented in this application.

[0069] In some embodiments, see Figure 1 In the control system of the fruit and vegetable preservation refrigerator provided in this application, the controller 40 is further configured as follows: In response to the detection module 50 detecting that the fruits and vegetables have been removed, the controller 40 controls the timing module 70 to stop timing and clears the storage information of the fruits and vegetables in the preservation compartment 10.

[0070] Specifically, the detection module 50 continuously monitors the state inside the preservation compartment 10. When a user removes fruits and vegetables from the preservation compartment 10, the detection module 50 detects that the fruits and vegetables have been removed and immediately sends a removal signal to the controller 40. In response to the detection module 50 detecting the removal, the controller 40 first sends a stop timing command to the timing module 70, controlling the timing module 70 to stop timing and prevent the timing module 70 from continuously recording invalid durations of removed fruits and vegetables. Simultaneously, the controller 40 clears the stored information of the fruits and vegetables in the preservation compartment 10, including the type of fruit and vegetable, the activated light operation parameters, and the recorded storage duration data. After clearing the stored information, the controller 40 releases memory space, preparing for the next time fruits and vegetables are placed into the preservation compartment 10.

[0071] In this embodiment, the controller 40 responds to the removal of fruits and vegetables by stopping the timer and clearing the stored information, thereby realizing the timely release of system resources, avoiding invalid data from occupying storage space and controller processing resources, and ensuring that the system can start working in a brand new state the next time fruits and vegetables are put in, thus improving the system's operating efficiency and stability.

[0072] In some embodiments, see Figure 2 This application also provides a control method for a fruit and vegetable preservation refrigerator, applied to the control system of the fruit and vegetable preservation refrigerator provided in the above embodiments, including: S100: Obtain the types of fruits and vegetables inside the cold storage compartment 10; S200: Based on the type of fruit and vegetable, call the corresponding light operation parameters for that type of fruit and vegetable from the set of light operation parameters for fruit and vegetable; S300: Determine the current storage stage based on the storage time of fruits and vegetables in the preservation compartment 10; S400 controls the operation of the lighting module based on the lighting parameters corresponding to the current storage stage.

[0073] In some embodiments, this application also provides a computer-readable storage medium, including: at least one computer instruction, the computer instruction being used to cause a computer to perform the steps of the control method for the fruit and vegetable preservation refrigerator provided in the above embodiments.

[0074] When computer instructions are loaded and executed by the computer, the steps of the control method for the fruit and vegetable preservation refrigerator that enable the computer to perform include, but are not limited to: obtaining the types of fruits and vegetables in the preservation compartment 10; calling the corresponding light operation parameters from the fruit and vegetable light operation parameter set based on the types of fruits and vegetables; determining the current storage stage based on the storage time of the fruits and vegetables in the preservation compartment 10; and controlling the operation of the light module 20 based on the light parameters corresponding to the current storage stage.

[0075] Specifically, the computer-readable storage medium can be a USB flash drive, external hard drive, read-only memory, random access memory, magnetic disk, or optical disk, or any other medium capable of storing program code. When the processor or microcontroller in the computer, such as the refrigerator controller 40, loads and executes the aforementioned computer instructions, the computer obtains the types of fruits and vegetables in the preservation compartment 10. Based on the obtained types of fruits and vegetables, the computer retrieves the corresponding lighting parameters from the fruit and vegetable lighting operation parameter set in the storage module 30. The retrieved lighting operation parameters include the lighting parameters corresponding to the fruit and vegetable type at multiple storage stages. Based on the storage time of the fruits and vegetables in the preservation compartment 10, the computer determines the current storage stage. Based on the determined lighting parameters corresponding to the current storage stage, the computer controls the operation of the lighting module 20. Once the current storage stage is determined, the computer extracts the lighting parameters corresponding to the current storage stage from the retrieved lighting operation parameters, generates corresponding control instructions based on the extracted lighting parameters, transmits the control instructions to the lighting module 20, and the lighting module 20 operates according to the operating mode indicated by the control instructions. As the storage duration continues to increase, the computer redetermines the current storage stage based on the updated storage duration. When the change in storage duration causes a change in the current storage stage, the computer extracts the lighting parameters corresponding to the new stage from the previously called lighting operation parameters and generates new control commands based on the new lighting parameters, which are then sent to the lighting module 20. The lighting module 20 then switches to the operation mode corresponding to the new storage stage.

[0076] For example, when the fruit and vegetable placed in the preservation compartment 10 is blueberries, the computer identifies the fruit and vegetable as blueberries. Based on this, the computer retrieves the corresponding light operation parameters for blueberries from the fruit and vegetable light operation parameter set in the storage module 30. These parameters include the light parameters corresponding to the first, second, and third storage stages. Based on the storage duration of the blueberries in the preservation compartment 10, if the storage duration is less than a first preset duration (e.g., 3 days), the computer determines the current storage stage as the first storage stage. The computer extracts the light parameters corresponding to the first storage stage from the retrieved blueberry light operation parameters and generates control commands based on these parameters, sending them to the light module 20. The light module 20 then operates according to the light parameters corresponding to the first storage stage. If the storage duration is greater than 3 days but less than or equal to 6 days, the computer determines the current storage stage as the second storage stage, extracts the corresponding light parameters from the retrieved blueberry light operation parameters, and controls the light module 20 to switch to the second storage stage. When the storage duration exceeds 6 days, the computer determines that the current storage stage is the third storage stage and controls the lighting module 20 to operate according to the lighting parameters corresponding to the third storage stage.

[0077] By executing the aforementioned computer instructions, the computer can perform the control method of the fruit and vegetable preservation refrigerator according to preset logic, completing the preservation operation by dynamically matching light parameters based on the type of fruit and vegetable and the storage duration. This process ensures that fruits and vegetables receive appropriate preservation light at different storage stages, avoiding a decline in preservation effect due to fixed light parameters.

[0078] As can be seen from the above technical solution, the computer-readable storage medium provided in this embodiment stores a computer program or instruction that implements the above control method. When the processor executes the program or instruction, it can call the corresponding light operation parameters based on the type of fruit and vegetable, determine the current storage stage based on the storage duration, and control the operation of the light module 20 according to the light parameters corresponding to the current storage stage. This solves the problem in the prior art that the light parameters are fixed and cannot be dynamically adjusted according to the storage duration of the fruit and vegetable, ensuring that the light output by the light module 20 always adapts to the needs of different storage stages of the fruit and vegetable, and improving the preservation effect of the fruit and vegetable.

The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
