[0002] As living standards improve, people have higher requirements for refrigerator preservation. Currently, some refrigerators on the market use ultraviolet sterilization to extend the shelf life of food. However, existing refrigerators usually use an alternating start-stop control method to sterilize the food in the refrigerator, which is not intelligent enough. Furthermore, when food does not need sterilization, the sterilization module in the refrigerator is still in sterilization mode, which leads to waste of electricity. Summary of the Invention

[0003] This application provides a refrigerator control method, storage medium, and refrigerator, which can solve the problem that the light adjustment of the light source component of existing refrigerators is not intelligent enough, resulting in the waste of electrical energy.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A method for controlling a refrigerator, wherein a light source assembly is provided in the storage compartment of the refrigerator, the method comprising:

[0006] When a preset item is placed in the storage room, the type and quality of the preset item are obtained and the first duration of the preset item being placed in the storage room is timed.

[0007] The first illumination intensity is determined based on the feature information and the first duration.

[0008] The light source assembly is controlled to irradiate the preset item with the first light intensity in order to sterilize the preset item.

[0009] In some embodiments, the feature information includes the quality and type of the preset item, and determining the first light intensity based on the feature information and the first duration includes:

[0010] The intensity parameter corresponding to the type of the preset item is determined according to the type of preset item and the preset parameter library. The preset parameter library includes a one-to-one correspondence between multiple item types and multiple intensity parameters.

[0011] The first illumination intensity is determined based on the intensity parameter, the mass, and the first duration.

[0012] In some embodiments, determining the first illumination intensity based on the intensity parameter, the mass, and the first duration includes:

[0013] The first light intensity is determined according to the following calculation formula:

[0014] Where I represents the first light intensity, q represents the intensity parameter, m represents the mass, and T represents the first duration.

[0015] In some embodiments, after determining the first illumination intensity according to the above formula, the method further includes:

[0016] Determine whether the first light intensity has decreased to a first preset intensity;

[0017] If the first light intensity decreases to a first preset intensity, the light intensity of the light source component is controlled to change periodically between the first preset intensity and a second preset intensity, wherein the second preset intensity is greater than the first preset intensity.

[0018] In some embodiments, controlling the light intensity of the light source assembly to periodically change between a first preset intensity and a second preset intensity includes:

[0019] If the light intensity of the light source component decreases to the first preset intensity, the light intensity of the light source component is increased by a first fixed intensity every first preset time interval until the light intensity of the light source component is increased to the second preset intensity.

[0020] If the light intensity of the light source component increases to the second preset intensity, then the light intensity of the light source component is reduced to a second fixed intensity every second preset time interval until the light intensity of the light source component is reduced to the first preset intensity.

[0021] In some embodiments, the feature information includes the mass of the preset item, and after obtaining the feature information of the preset item, it further includes:

[0022] Determine whether the mass of the preset item is lower than the first preset mass;

[0023] If the mass of the preset item is lower than the first preset mass, then the third preset intensity is used as the first light intensity, and the third preset intensity is less than the maximum light intensity of the light source component.

[0024] If the mass of the preset item is greater than or equal to the first preset mass, then the first light intensity is determined based on the characteristic information of the preset item and the first duration.

[0025] In some embodiments, after using a third preset intensity as the first illumination intensity, the method further includes:

[0026] Control the light source assembly to irradiate the preset item with the first light intensity for a third preset duration;

[0027] The illumination intensity of the light source component is controlled to change periodically between a third preset intensity and a fourth preset intensity, wherein the fourth preset intensity is greater than the third preset intensity.

[0031] A refrigerator storage medium storing a computer program, which executes the above-described refrigerator control method when the computer program is run.

[0032] A refrigerator, comprising:

[0033] Storage room;

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0048] This application provides a refrigerator control method, wherein a light source assembly is provided in the storage compartment of the refrigerator. The light source assembly is used to illuminate the storage compartment to sterilize and disinfect it. For example, please refer to [link to example]. Figure 1 , Figure 1 A first flowchart of a refrigerator control method provided in this application embodiment. The refrigerator control method includes the following steps S101-S104:

[0049] Step S101: When a preset item is placed in the storage room, obtain the feature information of the preset item and start timing the first time the preset item is placed in the storage room;

[0050] It should be noted that the characteristic information of the preset item may include its mass, type, freshness, volume, and moisture content. The type of preset item can be, for example, fruits, vegetables, seafood, meat, eggs, and other categories. The mass of the preset item refers to its weight, in units such as kilograms.

[0051] Step S102: Determine the first light intensity based on the preset item's feature information and the first duration;

[0052] Understandably, different light intensities are needed for items with different characteristics. For example, fruits and vegetables, which have short shelf lives and are more prone to spoilage, require stronger light intensities, while meat and eggs can be matched with slightly lower light intensities to conserve energy. Fresh ingredients can be matched with high light intensities, while cooked or processed, less perishable ingredients such as cured meats can be matched with slightly lower light intensities. Larger or heavier ingredients can be matched with high light intensities, while smaller or lighter ingredients can be matched with slightly lower light intensities. Furthermore, when items are first placed in the refrigerator's storage compartment, they carry a higher number of microorganisms, requiring strong ultraviolet light from the light source to sterilize and disinfect them. As time passes and the amount of microorganisms on the items gradually decreases, the light intensity of the light source can be gradually reduced to avoid wasting energy and save energy.

[0053] It should be noted that as the initial duration increases, the initial light intensity will continuously change to make the light intensity of the light source component more consistent with the actual situation of the preset item.

[0054] Step S103: Control the light source component to irradiate the preset item with a first light intensity to sterilize the preset item.

[0055] The refrigerator control method provided in this application determines the irradiation intensity of the light source component based on the characteristic information of the preset items and the duration of storage in the storage compartment. This ensures that the irradiation intensity of the light source component matches the actual situation of the preset items, resulting in good sterilization effect and improved intelligent adjustment of the irradiation intensity of the light source component. This avoids energy waste of the light source component and saves energy consumption of the light source component.

[0056] For further details, please refer to Figure 2 , Figure 2 A second flowchart illustrating a refrigerator control method provided in this application embodiment. The refrigerator control method includes the following steps S201-S214:

[0057] Step S201: Check whether the door of the storage room is open;

[0058] The refrigerator may be equipped with a door opening sensor, which is used to detect the open / closed state of the storage compartment door. If the storage compartment door is detected to be open, step S202 is executed; otherwise, the process returns to step S201.

[0059] Step S202: Control the light source assembly to turn off;

[0060] It is understandable that ultraviolet rays can damage the skin, eyes, and immune system when they irradiate the human body. Therefore, turning off the light source components when the door of the storage room is detected to be open can prevent the ultraviolet rays emitted by the light source components from causing harm to the human body.

[0061] Step S203: Check whether the door of the storage room is closed;

[0062] If the door to the storage room is not closed, the light source assembly remains closed until the door to the storage room is detected to be closed. When the door to the storage room is detected to be closed, step S204 is executed.

[0063] Step S204: Determine whether a preset item has been newly placed in the storage room;

[0064] In some embodiments, the refrigerator's storage compartment is equipped with multiple temperature sensors to detect the temperature of multiple temperature zones. For example, if the temperature rise of one or more temperature zones reaches a preset value after the door is opened and closed, it is confirmed that a preset item has been placed in the storage compartment. Alternatively, in other embodiments, several image acquisition devices can be installed in the refrigerator's storage compartment to acquire images of the interior of the storage compartment. The refrigerator's processor analyzes the acquired images to determine whether a preset item has been placed in the storage compartment.

[0065] If a preset item is placed in the storage room, proceed with steps S205-S206; otherwise, proceed with steps S207-S208.

[0066] Step S205: Obtain the mass of the preset item;

[0067] The refrigerator's storage compartment may be equipped with a weighing device that automatically weighs the items placed inside to determine the mass of any newly added, preset items. Users can also input / modify the mass of newly added, preset items directly through the refrigerator's display panel.

[0068] Step S206: Determine whether the mass of the preset item is greater than or equal to the first preset mass;

[0069] If the mass of the preset item is greater than or equal to the first preset mass, then proceed to step S209 below; otherwise, proceed to steps S207-S208 below. The first preset mass is, for example, 2 kg.

[0070] Step S207: Control the light source assembly to turn on at the third preset intensity;

[0071] The third preset intensity is less than the maximum light intensity of the light source component. For example, the third preset intensity is 20%. It is understood that if the storage room door is opened and closed and no new preset items are placed in, or the new items are of small weight, then it is not necessary to turn the light intensity of the light source component too high, so as to avoid wasting the energy of the light source component.

[0072] Step S208: After the light source component irradiates the preset item with the third preset intensity for the first preset duration, the light intensity of the light source component is controlled to change periodically between the third preset intensity and the fourth preset intensity, with the fourth preset intensity being greater than the third preset intensity.

[0073] It should be noted that controlling the periodic change of the light intensity of the light source component refers to the periodic increase-decrease-increase-decrease of the light intensity of the light source component, where the highest light intensity is the fourth preset intensity and the lowest is the third preset intensity. For example, the third preset intensity is 20% and the fourth preset intensity is 30%. If the light intensity of the light source component decreases to 20%, the light intensity of the light source component is increased by 1% every 20 minutes until the light intensity of the light source component increases to 30%; if the light intensity of the light source component increases to 30%, the light intensity of the light source component is decreased by 1% every 20 minutes until the light intensity of the light source component decreases to 20%, and so on.

[0074] Understandably, by adjusting the light intensity of the light source components as described above, the energy consumption of the light source components can be reduced while ensuring their sterilization effect.

[0075] Step S209: Obtain the type of the preset item and time the first duration for the preset item to be placed in the storage room;

[0076] The identification of preset item types can be achieved using infrared recognition technology. For example, an infrared emitter emits infrared rays, which, when they illuminate food, form reflected light waves. A processor analyzes the frequency and intensity of the light waves received by the receiver and compares them with a database to identify the type of food corresponding to the frequency and intensity of the light waves. In other embodiments, image analysis and other methods can also be used to identify preset item types.

[0077] The start time of the first duration is, for example, the moment when the door closes.

[0078] Step S210: Determine the strength parameter corresponding to the type of preset item based on the type of preset item and the preset parameter library. The preset parameter library includes a one-to-one correspondence between multiple item types and multiple strength parameters.

[0079] For example, the one-to-one correspondence between multiple item types and multiple strength parameters can be seen in Table 1 below:

[0080] Table 1: Comparison of Strength Parameters

[0081] Item types Strength parameter q Fruits 1 Vegetables 1.25 Seafood and fish 1.53 meat 1.67 Eggs 1.33 Other types 1.46

[0082] Step S211: According to the formula Determine the first illumination intensity, where I represents the first illumination intensity, q represents the intensity parameter, m represents the mass, and T represents the first duration.

[0083] As can be seen from the above formula, initially, when the first duration is 0, the light intensity of the light source component is at its maximum of 100%. This means that when the preset item is first placed in the storage room, the light source component irradiates the preset item with the strongest light intensity to sterilize it. As the first duration gradually increases, the first light intensity I gradually decreases. This means that as the preset item is irradiated with ultraviolet light, the number of microorganisms it carries gradually decreases, thus eliminating the need for excessively strong ultraviolet light irradiation and avoiding energy waste. Furthermore, different types of items correspond to different intensity parameters. The larger the intensity parameter, the greater the decrease in light intensity over time; the smaller the intensity parameter, the smaller the decrease in light intensity over time. The mass of the preset item also affects the rate of decrease in light intensity; the greater the mass, the smaller the decrease in light intensity; the smaller the mass, the greater the decrease in light intensity.

[0084] Step S212: Determine whether the first light intensity is less than or equal to the first preset intensity;

[0085] If the first light intensity is less than or equal to the first preset intensity, then step S214 is executed; otherwise, step S213 is executed. The first preset intensity is, for example, 15%.

[0086] Step S213: Control the light source assembly to illuminate the preset item with a first light intensity;

[0087] Understandably, before the first light intensity gradually decreases to the first preset intensity over time, the light source component irradiates ultraviolet light according to the first light intensity calculated by the above formula to complete the initial sterilization and disinfection of the newly placed preset items. After the first light intensity decreases to the first preset intensity, the light source component is controlled to adjust the light intensity in another mode (such as the mode exemplified in step S214) to perform subsequent continuous sterilization and disinfection of the newly placed preset items.

[0088] Based on the above explanation, it is understandable that the larger the intensity parameter, the greater the decrease in light intensity over time, and the shorter the total sterilization time in the initial stage; conversely, the smaller the intensity parameter, the smaller the decrease in light intensity over time, and the longer the total sterilization time in the initial stage. The quality of the preset item also affects the rate of decrease in light intensity; the greater the quality, the smaller the rate of decrease in light intensity, and the longer the total sterilization time in the initial stage; conversely, the smaller the quality, the greater the rate of decrease in light intensity, and the shorter the total sterilization time in the initial stage. The above-described method for adjusting the light intensity of the light source component allows for a better match between the light intensity and the actual condition of the preset item, and the adjustment of the light source component is more intelligent.

[0089] Step S214: Control the light intensity of the light source component to change periodically between a first preset intensity and a second preset intensity;

[0090] It should be noted that the second preset intensity is greater than the first preset intensity. For example, the second preset intensity is 30%. If the light intensity of the light source component decreases to 15%, the light intensity of the light source component is increased by 1% every first preset time interval until the light intensity of the light source component increases to 30%; if the light intensity of the light source component increases to 30%, the light intensity of the light source component is decreased by 1% every first preset time interval until the light intensity of the light source component decreases to 15%, and this cycle repeats. The first preset time interval is, for example, 20 minutes.

[0091] In practical applications, when a user places a preset item into the storage compartment, the refrigerator matches different sterilization modes according to the weight of the new preset item. If the weight is heavy, the first sterilization mode is used, which calculates a suitable first light intensity based on the weight and type of the preset item and the first time it has been in the storage compartment, and controls the light source component to irradiate with the first light intensity until the first light intensity weakens to the preset value. Then, the light source component is controlled to adjust the intensity in a cycle of strong and weak changes. If the weight is light, the second sterilization mode is used. In the second sterilization mode, the light source component first irradiates with a lower preset intensity for a period of time and then adjusts the intensity in a cycle of strong and weak changes.

[0092] The refrigerator control method provided in this application matches different sterilization modes to preset items based on their quality, and adjusts the light intensity of the light source component according to the quality, type, and first duration of the preset items in the storage compartment, so as to match the preset items with a suitable sterilization intensity, resulting in good sterilization effect. Furthermore, it makes the adjustment of the light source component more intelligent and reduces the energy waste of the light source component.

[0093] This application embodiment also provides a refrigerator storage medium, on which a computer program is stored, and the computer program executes the above-described refrigerator control method when it runs.

[0094] This application also provides a refrigerator, which can be a side-by-side refrigerator, a double-door refrigerator, a French door refrigerator, a French door refrigerator, etc. For examples, please refer to... Figures 3-4 , Figure 3 This is a schematic diagram of a first structural embodiment of a refrigerator provided in this application. Figure 4 This is a second structural schematic diagram of a refrigerator provided in an embodiment of this application. The refrigerator 100 includes a storage compartment 110, a light source assembly 120, and a processor 130.

[0095] A light source assembly 120 is disposed in the storage room 110, for example, on the inner wall or top wall of the storage room 110. The light source assembly 120 may include at least one of an ultraviolet light source, an infrared light source, or other light sources with bactericidal effects. The light source assembly 120 is used to disinfect items inside the storage room 110. A processor 130 is connected to the light source assembly 120 and is used to: when a preset item is newly placed in the storage room 110, acquire characteristic information of the preset item and time a first duration of time the preset item has been placed in the storage room 110; determine a first light intensity based on the characteristic information and the first duration; and control the light source assembly 120 to irradiate the preset item with the first light intensity.

[0096] For further details, please refer to [link / reference]. Figure 5 , Figure 5 This is a schematic diagram of a third structure of a refrigerator provided in an embodiment of this application.

[0097] The door switch detection module 131 is used to detect the open / closed state of the door of the storage room 110. The item detection module 132 is connected to the door switch detection module 131. For example, when the door switch detection module 131 detects that the door is open and then closed, it sends a first signal to the item detection module 132 so that the item detection module 132 can detect whether a preset item has been newly placed inside the storage room 110.

[0098] Infrared recognition module 133 is connected to item detection module 132 and is used to identify the type of preset item when a preset item is newly placed in storage room 110. Weighing module 134 is connected to item detection module 132 and is used to obtain the mass of the preset item when a preset item is newly placed in storage room 110. Timing module 135 is connected to item detection module 132 and is used to time the first duration of the preset item being placed in storage room.

[0099] The control module 136 is connected to the infrared recognition module 133, the weighing module 134, and the timing module 135, and is used to connect to the light source assembly 120. The control module 136 is used to determine the first light intensity according to the type, quality and first duration of the preset item, and to control the light source assembly 120 to irradiate the preset item with the first light intensity.

[0100] The refrigerator provided in this application determines the irradiation intensity of the light source component based on the characteristic information of the preset items, such as type, quality, and duration of storage in the storage compartment. This ensures that the light intensity of the light source component matches the actual situation of the preset items, resulting in good sterilization effect and improved intelligent adjustment of the light intensity of the light source component. This avoids energy waste of the light source component and saves energy consumption of the light source component.
