[0001] This invention relates to the field of refrigerator technology, and in particular to a refrigerator control method, controller, refrigerator, and storage medium. Background Technology

[0002] Sunlight is essential for fruits and vegetables to maintain growth and synthesize various nutrients. Freshly harvested fruits and vegetables retain a certain degree of vitality, but during refrigeration, they continue to respire, consuming their own nutrients and gradually reducing their nutritional value. In recent years, however, the demand for high-quality, high-nutrient fruits and vegetables has become increasingly strong.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various implementations. Simultaneously, the steps or actions in the method description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed.

[0051] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0052] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0053] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0054] It's important to note that sunlight is essential for fruits and vegetables to maintain growth and synthesize various nutrients. Freshly harvested fruits and vegetables retain a certain degree of vitality, but during refrigeration, they continue to respire, consuming their own nutrients and gradually reducing their nutritional value. In recent years, however, the demand for high-quality, highly nutritious fruits and vegetables has become increasingly strong. Therefore, maximizing the nutritional content of fruits and vegetables while preserving their freshness is crucial.

[0055] Currently, the technology of using specific light waves for fruit and vegetable preservation has been applied in the refrigerator industry. However, most of these technologies focus on extending the shelf life and preventing nutrient loss. This solution focuses on reverse aging of harvested fruits and vegetables to enhance various nutrients, making them more nutritious. Furthermore, while tropical fruits are delicious, storage is a challenge. At room temperature, tropical fruits have a short shelf life and rot before they can be consumed, resulting in waste. If stored in ordinary refrigeration (4-5℃), unripe tropical fruits cannot complete their ripening process and are prone to chilling injury, resulting in poor taste.

[0056] Based on the above, embodiments of the present invention provide a refrigerator control method, a controller, a refrigerator, and a storage medium. The refrigerator includes a crisper drawer, which includes a light-emitting component. The light-emitting component illuminates a first color temperature and a second color temperature. The refrigerator control method includes, but is not limited to, the following steps: when the crisper drawer is closed, turning on the light-emitting component and recording the continuous operating time of the light-emitting component; wherein, the light-emitting component alternately illuminates the first color temperature and the second color temperature during the continuous operating time; and adjusting the light intensity of the light-emitting component according to the continuous operating time and preset operating conditions.

[0057] Understandably, related technologies generally use single or multiple color temperatures to continuously irradiate fruits and vegetables for preservation, which can extend the preservation time, but results in significant nutrient loss. However, the embodiments of this invention can stimulate fruit and vegetable growth through alternating irradiation at different color temperatures, thereby improving the nutritional content of the fruits and vegetables. Furthermore, by adjusting the duration of continuous irradiation, the temperature rise inside the preservation drawer can be controlled, ensuring a balance between nutrient enhancement and preservation quality.

[0058] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0059] like Figure 1 As shown, Figure 1 This is a schematic diagram of a system architecture platform for executing a refrigerator control method according to an embodiment of the present invention.

[0060] The system architecture platform 1000 of this embodiment includes one or more processors 1001 and a memory 1002. Figure 1 The example uses a processor 1001 and a memory 1002.

[0061] Processor 1001 and memory 1002 can be connected via a bus or other means. Figure 1 Taking the example of a connection between China and Israel via a bus.

[0062] Memory 1002, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory 1002 may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, memory 1002 may optionally include memory 1002 remotely located relative to processor 1001, and these remote memories can be connected to the system architecture platform 1000 via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0063] Those skilled in the art will understand that Figure 1The device structure shown does not constitute a limitation on the system architecture platform 1000 and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0064] exist Figure 1 In the system architecture platform 1000 shown, the processor 1001 can be used to call the refrigerator control program stored in the memory 1002, thereby realizing the refrigerator control method.

[0065] Based on the hardware structure of the above-mentioned system architecture platform 1000, various embodiments of the refrigerator of the present invention are proposed.

[0066] Specifically, the food preservation drawer of the present invention includes a light-illuminating component. This drawer is used in a refrigerator and is placed in the refrigerator's crisper compartment. The refrigerator can refer to a broad range of refrigeration and storage devices, such as refrigerators, freezers, and freezers. More specifically, the refrigerator in this embodiment includes, but is not limited to, a food preservation drawer, a crisper compartment, and a controller. The food preservation drawer is placed in the crisper compartment and includes a light-illuminating component. The color temperature irradiated by the light-illuminating component includes a first color temperature and a second color temperature. The controller may include, for example, […]. Figure 1 The processor 1001 and memory 1002 are shown. It should be noted that the lighting component can be a single light source or an integrated set of multiple light sources. If it is a single light source, the color temperature of the illumination is changed by altering the illumination frequency of the light source. If it is multiple light sources, such as two light sources, each light source corresponds to a specific color temperature. Color temperatures include red, orange, blue, or other color temperatures.

[0067] It should be noted that, in the embodiments of the present invention, red and blue are optimal for the first and second color temperatures. In a specific example, the lighting component is a dual-core LED red and blue light panel.

[0068] In another embodiment, the food preservation drawer includes a light-illuminating component; a food preservation shell with a sealable receiving space; a ventilation device disposed on the food preservation shell, which enables the receiving space to communicate with or isolate from the refrigerator compartment. In another embodiment, the food preservation drawer includes a light-illuminating component; a food preservation shell with a sealable receiving space; a ventilation device disposed on the food preservation shell, which enables the receiving space to communicate with or isolate from the refrigerator compartment; and a temperature sensor. Specifically, to achieve communication or isolation between the receiving space and the refrigerator compartment, the ventilation device can be an electrically controlled one-way valve or a mechanically controlled device. For example, in some embodiments, the mechanically controlled device can be a damper driven by a drive device, which can controllably open or close the communication between the receiving space and the refrigerator compartment.

[0069] Based on the modular hardware structure of the refrigerator described above, various embodiments of the refrigerator control method of the present invention are proposed.

[0070] First, it should be noted that color temperature is a unit of measurement indicating the color components contained in light. This invention uses color temperature to represent different colors of light. For example, the first color temperature represents red light, and the second color temperature represents blue light. Theoretically, blackbody temperature refers to the color of an absolute blackbody after being heated from absolute zero (-273°C). When heated, a blackbody gradually changes from black to red, then to yellow, then to white, and finally emits blue light. When heated to a certain temperature, the spectral composition of the light emitted by the blackbody is called the color temperature at that temperature, measured in "K" (Kelvin). If the light emitted by a certain light source has the same spectral composition as the light emitted by a blackbody at a certain temperature, it is called a color temperature of that K. For example, if the color of the light emitted by a 100W light bulb is the same as the color of an absolute blackbody at 2527°C, then the color temperature of the light emitted by this light bulb is: (2527 + 273) K = 2800 K.

[0071] like Figure 2 As shown, Figure 2 This is a flowchart of a refrigerator control method according to an embodiment of the present invention. The refrigerator control method of the present invention includes, but is not limited to, steps S100 and S200.

[0072] Step S100: When the freshness drawer is in freshness enhancement mode and closed state, turn on the light component and record the continuous running time of the light component; wherein, the light component alternately irradiates the first color temperature and the second color temperature during the continuous running time.

[0073] Specifically, the operating modes of the refrigeration drawer include a freshness-enhancing mode and a ripening mode, and the drawer's closing status includes a closed state and an open state. When the refrigeration drawer is in the freshness-enhancing mode or the closed state, it indicates that the drawer is in freshness-enhancing working condition and the light-emitting component needs to be turned on for irradiation. Taking fruits and vegetables placed in the refrigeration drawer as an example, irradiating the fruits and vegetables can promote photosynthesis and improve their nutritional content. In addition, this embodiment of the invention further stimulates the growth of fruits and vegetables by alternating between a first color temperature and a second color temperature during continuous operation of the light-emitting component, thereby improving the nutritional content of the fruits and vegetables.

[0074] It should be noted that the operating mode can be specified by the user. For example, the user places the fruits and vegetables to be preserved in the refrigeration drawer and selects the freshness enhancement mode. Alternatively, the operating mode can be determined by identifying the fruits and vegetables inside the refrigeration drawer without user specification. The closure status can be detected by sensors to determine whether the refrigeration drawer is closed or open. The embodiments of this invention do not specifically limit the method for detecting the closure status of the refrigeration drawer.

[0075] Step S200: Adjust the light intensity of the lighting component according to the continuous running time and preset operating conditions.

[0076] Specifically, the preset operating conditions can refer to a runtime threshold, and the light intensity of the lighting component can be adjusted based on the comparison between the continuous runtime and the preset operating conditions. For example, if the continuous runtime is less than or equal to the runtime threshold, the light intensity of the lighting component is increased or maintained. If the continuous runtime is greater than the runtime threshold, the light intensity of the lighting component is decreased to reduce the heat generated by irradiation, thereby reducing the temperature rise inside the preservation drawer. Therefore, this embodiment of the invention can control the temperature rise inside the preservation drawer by adjusting the light intensity through the continuous runtime of the light, ensuring a balance between nutrient enhancement and preservation quality of fruits and vegetables. It is understood that fruits and vegetables continuously lose nutrients due to respiration after harvesting. This embodiment of the invention can achieve nutrient enhancement of fruits and vegetables after harvesting: by alternately turning on the first color temperature (red light) and the second color temperature (blue light), the anthocyanins, polyphenols, chlorophyll, soluble solids, and other nutrients in fruits and vegetables are enhanced. At the same time, by adjusting the light intensity through the continuous runtime of the light, the temperature rise inside the preservation drawer can be controlled to be less than the temperature rise threshold (0.5℃), ensuring a balance between nutrient enhancement and preservation quality of fruits and vegetables.

[0077] In one specific example, if the continuous runtime exceeds a runtime threshold, the light intensity of the illumination component is adjusted to be lower than a preset first light intensity threshold, and maintained for at least a preset first dwell time. It should be noted that the crisper drawer is placed in the refrigerator compartment, where the temperature is approximately 4 to 5 degrees Celsius. Within the runtime threshold after activation, the illumination component experiences a certain temperature rise. However, after the continuous runtime exceeds the runtime threshold, the heat generated by the illumination component under the first light intensity threshold and during the first dwell time is insufficient to raise the temperature of the crisper drawer. That is, the crisper drawer will continue to cool down under the first light intensity threshold until it reaches the preset refrigerator temperature of the refrigerator compartment. In one specific example, the runtime threshold is 10 minutes, the first light intensity threshold is zero, and the first dwell time is 50 minutes.

[0078] It should be noted that during the first dwell time, if the refrigerator drawer is detected to change from an open state to a closed state, the lighting component is restarted. After the first dwell time ends, if the refrigerator drawer is still closed, the lighting component is restarted. In this embodiment of the invention, the ambient temperature rise refers to the temperature increase within the refrigerator drawer. For example, if the refrigerator drawer has a containment space, the ambient temperature rise refers to the temperature increase within that containment space.

[0079] like Figure 3 As shown, the duration of continuous operation in step S100 is obtained through the following steps:

[0080] Step S210: During the continuous illumination of the light-emitting component, record the first running time of the light-emitting component illuminating the first color temperature and the second running time of the light-emitting component illuminating the second color temperature.

[0081] Step S220: Obtain the continuous runtime based on the first runtime and the second runtime.

[0082] Specifically, after the lighting component is turned on, it continuously emits light. During the light emission process, the first color temperature and the second color temperature alternately illuminate the area, and the continuous operating time is obtained by summing the first operating time and the second operating time. The first operating time and the second operating time can be equal or unequal. In a specific example, after the lighting component is turned on, it first illuminates the area with the first color temperature for the first operating time, and then illuminates the area with the second color temperature for the second operating time.

[0083] In another specific example, the first and second running times are obtained by irradiating each color temperature for multiple intermediate durations, and then the first running time and the second running time are obtained by summing the multiple intermediate durations.

[0084] like Figure 4 As shown, after turning on the illumination component in step S100, the control method of this embodiment of the invention further includes, but is not limited to, steps S310 to S320.

[0085] Step S310: Obtain the ambient temperature rise value of the food storage drawer;

[0086] Step S320: Adjust the light intensity of the light-emitting component according to the ambient temperature rise value.

[0087] Specifically, when the light-emitting component is turned on, the light can stimulate the increase of nutrients in fruits and vegetables. However, the light generates heat, causing the ambient temperature inside the fresh-keeping drawer to rise. Excessively high ambient temperatures can negatively impact the preservation of fruits and vegetables. Therefore, this embodiment of the invention adjusts the light intensity of the light-emitting component based on the ambient temperature rise to manage the increased heat, thereby controlling the ambient temperature of the fresh-keeping drawer and ensuring optimal preservation.

[0088] In step S320, when the ambient temperature rise exceeds a preset temperature rise threshold, the lighting component is turned off. In one example, after turning off the lighting component, the duration of the shutdown is recorded. The shutdown duration must be at least a preset shutdown duration threshold. If the refrigeration drawer is closed after the shutdown duration threshold, the lighting component is restarted.

[0089] like Figure 5 As shown, the ambient temperature rise value in step S310 is obtained through the following steps, including:

[0090] Step S410: Obtain the first color temperature light intensity of the first color temperature and the second color temperature light intensity of the second color temperature;

[0091] Step S420: Obtain the first increase in heat based on the first color temperature light intensity and the first running time;

[0092] Step S430: Obtain the second increase in heat based on the second color temperature light intensity and the second running time;

[0093] Step S440: Obtain the ambient temperature rise value based on the first increase in heat and the second increase in heat.

[0094] Specifically, the product of light intensity and operating time determines the increased heat, and the sum of the first and second increased heat can be used to determine the total increased heat, which in turn determines the ambient temperature rise. Furthermore, determining the ambient temperature rise based on the total increased heat also needs to consider parameters such as the volume of the food storage drawer; a larger volume results in a smaller ambient temperature rise. Therefore, in one embodiment, the ambient temperature rise is determined based on 50% or 60% of the total increased heat.

[0095] In one embodiment, the food preservation drawer further includes a temperature sensor. The ambient temperature rise value in step S310 can also be obtained through the following steps: detecting the initial ambient temperature and the current ambient temperature using the temperature sensor; calculating the temperature difference between the current ambient temperature and the initial ambient temperature; and obtaining the ambient temperature rise value based on the temperature difference. Specifically, the initial ambient temperature refers to the ambient temperature before or immediately after the light-emitting component is turned on, and the current ambient temperature is the real-time ambient temperature after the light-emitting component is turned on. The ambient temperature rise value is determined based on the difference between the initial ambient temperature and the current ambient temperature.

[0096] like Figure 6 As shown, Figure 6 This is a flowchart of a refrigerator control method provided in another embodiment of the present invention. The refrigerator control method of the present invention includes, but is not limited to, steps S510 and S530.

[0097] Step S510: When the food preservation drawer is in ripening mode and closed, obtain the initial ambient temperature of the food preservation drawer.

[0098] Step S520: If the initial ambient temperature is less than the preset first ripening temperature threshold, turn on the light component.

[0099] Step S530: Obtain the current ambient temperature of the preservation drawer, and adjust the light intensity of the light component according to the current ambient temperature and the preset second ripening temperature threshold; wherein, the second ripening temperature threshold is greater than the first ripening temperature threshold.

[0100] Specifically, when the refrigeration drawer is in ripening mode or closed, it indicates that the drawer is in ripening operation mode and requires the light component to be turned on for irradiation. Taking tropical fruit placed in the drawer as an example, irradiating the tropical fruit can promote photosynthesis and increase its nutritional content. Furthermore, the continuous irradiation by the light component provides heat, keeping the ambient temperature inside the drawer between the first and second ripening temperature thresholds, thus preserving and ripening the tropical fruit. In addition, the light intensity is adjusted according to the current ambient temperature and the second ripening temperature threshold to prevent the ambient temperature inside the drawer from becoming too high, which would affect the preservation effect of the tropical fruit. It is understood that the storage and ripening process of tropical fruit has high temperature requirements, which existing refrigeration environments cannot meet. This invention can satisfy the storage and ripening needs of tropical fruit: by utilizing the temperature rise generated by the red and blue light emitted by the light component and a temperature sensor, the ambient temperature of the refrigeration drawer is controlled between the first ripening temperature threshold (9℃) and the second ripening temperature threshold (14℃) for tropical fruit storage, which can extend the storage period and ensure preservation, while also ensuring normal ripening and improving taste.

[0101] like Figure 7 As shown, the illumination component has a first illumination intensity and a second illumination intensity, wherein the first illumination intensity is greater than the second illumination intensity; step S530 includes, but is not limited to, steps S610 to S620.

[0102] Step S610: If the current ambient temperature is less than the preset second ripening temperature threshold, control the light component to operate at least at the first light intensity.

[0103] Step S620: If the current ambient temperature is greater than the preset second ripening temperature threshold, control the light component to operate at the second light intensity, and after the light component has been operating for a preset light duration, adjust the light intensity of the light component to be less than the preset second light intensity threshold, and maintain it for at least the preset second dwell time; the second light intensity threshold is less than the second light intensity.

[0104] Specifically, in the ripening mode, the ambient temperature inside the refrigerator drawer is ideally between the first ripening temperature threshold and the second ripening temperature threshold. Therefore, if the current ambient temperature is lower than the second ripening temperature threshold, the light component can be controlled to continue providing light at the first light intensity, at which point the ambient temperature inside the refrigerator drawer will either rise or at least remain unchanged. If the current ambient temperature is higher than the second ripening temperature threshold, the light component is controlled to provide light at the second light intensity. Since the refrigerator drawer is located in the refrigeration room, the ambient temperature inside the refrigerator drawer will gradually decrease, and after a preset light exposure time, the light intensity of the light component will be further reduced, for example, by turning off the light component to reduce the light intensity to zero, i.e., no longer providing light, and maintaining the second dwell time. After the second dwell time ends, the initial ambient temperature of the refrigerator drawer is re-acquired.

[0105] It should be noted that in step S620, if the current ambient temperature is greater than the second ripening temperature threshold, the light component can be directly turned off to stop providing light, and this makes it easier to control the ambient temperature inside the refrigeration drawer. However, considering that the refrigeration drawer is located in a cold storage room, directly reducing the light intensity to zero, i.e., stopping the provision of light, would affect the ripening effect of tropical fruits. Therefore, in this embodiment of the invention, even if the current ambient temperature is greater than the second ripening temperature threshold, the light component is first operated at the second light intensity, and after a preset light exposure time, the light intensity of the light component is reduced to below the second light intensity threshold to prevent the ambient temperature inside the refrigeration drawer from becoming too high, thus preserving the ripening and preservation effects under the ripening mode.

[0106] By controlling the refrigerator's control process through the above steps, in the freshness-enhancing mode, alternating irradiation with different color temperatures stimulates the growth of fruits and vegetables, thereby improving their nutritional content. Furthermore, adjusting the light intensity by controlling the duration of continuous light exposure controls the temperature rise within the crisper drawer, ensuring a balance between nutrient enhancement and preservation quality. In the ripening mode, the temperature rise generated by the light source and a temperature sensor are used to control the ambient temperature of the crisper drawer between the first and second ripening temperature thresholds. This is suitable for storing tropical fruits, extending the storage period to ensure preservation while also guaranteeing normal ripening and improving taste.

[0107] The control method of the present invention will be illustrated below through four practical examples.

[0108] Example 1: Turning on the refrigerator (refer to...) Figure 8 Therefore, the refrigerator control methods in Example 1 include:
