Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology. More specifically, it relates to a light-preserving refrigerator and its control method. Background Technology

[0002] Fruits and vegetables continue photosynthesis after harvesting. Suitable light promotes this light reaction, extending their shelf life and improving their nutritional content and edibility. Providing adequate light during refrigerator storage can further extend the shelf life of fruits and vegetables.

[0003] In related technologies, the light source inside the refrigerator is usually set at the top or side of the refrigerator compartment. If too many items are stored in the refrigerator compartment, the items will block each other, resulting in insufficient light for fruits and vegetables. As a result, the fruits and vegetables cannot continue to carry out light reactions, and their shelf life is shorter. Summary of the Invention

[0004] This application provides a light-preservation refrigerator and its control method to extend the preservation time of fruits and vegetables.

[0005] In a first aspect, embodiments of this application provide a light-preserving refrigerator, comprising:

[0006] The enclosure is designed with a refrigeration compartment.

[0007] A shelf assembly, slidably disposed within the refrigeration room; the shelf assembly includes:

[0008] Shelves, wherein the shelves are translucent;

[0009] A light source, located at the end of the shelf, is used to provide illumination to the shelf;

[0010] The shelf also includes:

[0011] Multiple light-scattering components are disposed inside the shelf, and the density of the light-scattering components inside the shelf is negatively correlated with the distance between the light sources, so as to scatter the light emitted by the light sources onto the surface of the shelf.

[0012] In the above technical solution, the shelf emits light through light-diffusing components, providing illumination to the fruits and vegetables placed on the shelf. This effectively avoids the problem of insufficient light caused by mutual shading between fruits and vegetables, thereby improving the light-preserving effect on fruits and vegetables. At the same time, by deploying more light-diffusing components in the shelf away from the light source, more light-diffusing components diffuse the light in areas with weaker light intensity, thus offsetting the light intensity attenuation caused by the increase in propagation distance. This results in a high consistency and uniformity of light intensity scattered from all positions on the shelf surface, ensuring the preservation effect on fruits and vegetables stored in all positions.

[0013] In some embodiments, the light source includes a plurality of spaced-apart LED beads, and includes at least two different LED beads of different colors.

[0014] The above technical solution, through the design of LED beads of various colors, can provide a more suitable light environment for fruits and vegetables, further improving the preservation effect.

[0015] In some embodiments, two adjacent LEDs emit different colors.

[0016] This setup, through the complementary effect of two adjacent different colors of light, helps to improve the overall efficiency of photosynthesis, further enhancing the preservation effect.

[0017] In some embodiments, the spacing between two adjacent LEDs is related to at least one of the size of the two adjacent LEDs, the wavelength of light emitted by the two adjacent LEDs, and the bandwidth.

[0018] In some embodiments, the larger the size of two adjacent LED beads, the larger the spacing between them; and / or, the greater the wavelength difference between the light emitted by two adjacent LED beads, the larger the spacing between them; and / or, the greater the bandwidth difference between the light emitted by two adjacent LED beads, the larger the spacing between them.

[0019] In some embodiments, the light source includes red and blue LEDs spaced apart.

[0020] Since red and blue light are the most suitable light sources for photocatalysis, this setting can enhance the effect of photocatalysis.

[0021] In some embodiments, the spacing d between adjacent red LEDs and blue LEDs falls within the following range:

[0022] 1.35 mm ≤ d, and d ≤ 2.35 mm.

[0023] In some embodiments, the spacing between adjacent diffuser components is equal in a direction parallel to the direction of the light source arrangement.

[0024] In some embodiments, in the direction perpendicular to the arrangement direction of the light sources, the spacing between adjacent diffuser components is negatively correlated with the distance between the light sources.

[0025] In some embodiments, the spacing between adjacent astigmatic elements is reduced proportionally in the astigmatic direction of the light source.

[0026] In some embodiments, in the parallel direction of the light source arrangement, the spacing between adjacent diffuser components is equal to the spacing between two adjacent LED beads.

[0027] Based on the light source intensity distribution rules and scattering principles, the above settings can provide an optimal position for the light source and the diffused light structure, which can not only achieve uniform light emission from the shelves, but also maximize the preservation effect of fruits and vegetables.

[0028] In some embodiments, the light-diffusing component has a perforated structure.

[0029] In some embodiments, the aperture of the astigmatism component is less than or equal to 1 mm, and / or the aperture depth of the astigmatism component is less than 5 mm.

[0030] In some embodiments, the aperture r of the astigmatism component is within the following range:

[0031] 0.3 mm ≤ r, and r ≤ 0.7 mm;

[0032] And / or,

[0033] The aperture depth h of the light-scattering component falls within the following range:

[0034] 1 mm ≤ h, and h ≤ 3 mm.

[0035] With the above settings, the shelf can have sufficient load-bearing strength while ensuring the effect of photosynthetic preservation.

[0036] In some embodiments, the upper or lower surface of the shelf is coated with a catalyst material;

[0037] The catalyst material is used to sterilize the refrigeration chamber under the irradiation of the light source.

[0038] In some embodiments, the light source further includes:

[0039] Multiple sterilization components are disposed between two adjacent LED beads for sterilizing the refrigeration chamber.

[0040] In some embodiments, the shelf includes:

[0041] A shelf, wherein the light-diffusing component is disposed inside the shelf;

[0042] An mounting strip is provided at the edge of the shelf, and the light source is provided within the mounting strip.

[0043] With this setup, the mounting strip can protect the light source, reducing the possibility of damage to it.

[0044] In some embodiments, the mounting strip has a channel structure, which includes an optical channel portion and a plug-in channel portion;

[0045] The light source is disposed in the light channel section;

[0046] At least a portion of the shelf is inserted into the insertion channel.

[0047] This setup allows the lamp body and shelf to be assembled using mounting strips.

[0048] In some embodiments, the sidewall of the light channel portion has a reflective curved surface, the light emission direction of the light source is toward the reflective curved surface, and the reflective curved surface is configured to reflect at least a portion of the light from the light source and then obliquely direct it toward the end face of the shelf.

[0049] With this configuration, light can exit from the upper and / or lower surfaces of the shelf after it hits the shelf, reducing the light flux loss caused by light exiting from the end face of the shelf when the light enters perpendicularly to the end face of the shelf. This improves the utilization rate of light and the lighting effect on items above and / or below the shelf.

[0050] In some embodiments, the shelf further includes a light-diffusing element disposed within the channel structure and disposed on the end face of the shelf.

[0051] With this configuration, the light diffuser can scatter the light emitted by the light source, and the scattered light is directed toward the end face of the shelf, making the light distributed more evenly toward the end face of the shelf, thereby reducing glare and shadows and providing a soft and uniform lighting effect.

[0052] Secondly, embodiments of this application provide a control method for a food preservation refrigerator, the refrigerator comprising:

[0053] The enclosure is designed with a refrigeration compartment.

[0054] A shelf assembly, slidably disposed within the refrigeration room; the shelf assembly includes:

[0055] Shelves, wherein the shelves are translucent;

[0056] A light source, located at the end of the shelf, is used to provide illumination to the shelf;

[0057] The shelf also includes:

[0058] Multiple light-diffusing components are disposed inside the shelf, and the density of the light-diffusing components arranged inside the shelf is negatively correlated with the distance between the light sources;

[0059] A controller connected to the light source is configured to:

[0060] The light source is controlled to emit light so that the light emitted by the light source is scattered onto the surface of the shelf through the light-scattering component.

[0061] In some embodiments, the refrigerator further includes:

[0062] A food ingredient recognition component is installed inside the refrigeration room and connected to the controller;

[0063] The controller is configured to:

[0064] Based on the recognition result of the food ingredient recognition component, the light source is controlled to emit light, or to stop emitting light.

[0065] Thirdly, embodiments of this application provide a computer-readable storage medium storing computer-executable instructions, which, when executed by a processor, are used to implement the first aspect and / or various possible implementations of the first aspect.

[0066] Fourthly, embodiments of this application provide a computer program product, including a computer program that, when executed by a processor, implements the first aspect and / or various possible implementations of the first aspect.

[0067] The photo-preservation refrigerator and its control method provided in this application include: a refrigerator body with a refrigeration compartment; and a shelf assembly slidably disposed within the refrigeration compartment. The shelf assembly includes: a shelf that is translucent; a light source disposed at the end of the shelf for providing illumination; and multiple light-diffusing components disposed inside the shelf, wherein the density of the light-diffusing components inside the shelf is negatively correlated with the distance between the light sources, for scattering the light emitted by the light sources onto the surface of the shelf. In the above technical solution, the shelf emits light through the light-diffusing components, providing illumination to the fruits and vegetables placed on the shelf. This effectively avoids the problem of insufficient light caused by mutual shading between fruits and vegetables, thereby improving the photo-preservation effect on fruits and vegetables. Meanwhile, by deploying more light-diffusing components in the shelves at positions away from the light source, more light-diffusing components diffuse the light in areas with weaker light intensity, thereby offsetting the light intensity attenuation caused by the increase in propagation distance. This results in a higher consistency and uniformity of light intensity scattered from various positions on the shelf surface, ensuring the preservation effect of fruits and vegetables stored in each position.

[0089] Photosynthesis is a fundamental process for plant growth and development, directly affecting the accumulation of nutrients in fruits and vegetables. The effects of different wavelengths of light on the nutritional indicators of fruits and vegetables are mainly reflected in the following aspects:

[0090] 1. Blue light: Blue light can promote the synthesis of chlorophyll in plants, thereby improving the efficiency of photosynthesis. In addition, blue light can also promote the synthesis of some organic substances in plants, such as proteins and sugars, thereby improving the nutritional value of fruits and vegetables.

[0091] 2. Red light: Red light also promotes photosynthesis in plants. It can accelerate energy conversion within the plant and increase the efficiency of photosynthesis. Furthermore, red light can promote the synthesis of certain bioactive substances in plants, such as antioxidants, thereby improving the disease resistance and nutritional value of fruits and vegetables.

[0092] 3. Far-red light: Far-red light has an important impact on plant growth and development. It can regulate plant growth rhythms and promote flowering and fruiting. However, excessive far-red light may inhibit plant photosynthesis, thereby affecting the accumulation of nutrients in fruits and vegetables.

[0093] 4. Ultraviolet (UV) light: The effects of UV light on plants are complex. Appropriate amounts of UV light can promote the synthesis of certain bioactive substances in plants, such as phenolic compounds, thereby improving the disease resistance and nutritional value of fruits and vegetables. However, excessive UV light may inhibit photosynthesis, thus affecting the accumulation of nutrients in fruits and vegetables.

[0094] Photosynthetic growth (photosynthetic growth) refers to the ability of photosynthetic pigments on plant chloroplasts to absorb light energy of specific wavelengths and convert it into stable chemical energy through light and dark reactions within the plant, thus enabling continued growth.

[0095] Since fruits and vegetables continue to photosynthesize after harvesting, suitable light will promote this light reaction, which can not only extend their shelf life but also improve their nutritional content and edibility. If suitable light is provided during refrigerator storage after harvesting (i.e., photosynthetically preserving the fruits and vegetables), their shelf life can be further extended.

[0096] In related technologies, the light source of a refrigerator is usually located at the top or side of the refrigerator compartment. If too many items are stored in the refrigerator compartment, the mutual blocking between the items can lead to insufficient light for some fruits and vegetables, preventing them from continuing their photoreaction process and reducing their freshness and quality. At the same time, the internal lighting of the refrigerator will be affected, making it difficult for users to clearly see the items inside, resulting in a poor user experience.

[0097] In view of this, this application provides a fresh-keeping refrigerator and its control method. By setting a light source on the end side of the shelf of the fresh-keeping refrigerator (hereinafter referred to as the refrigerator) and setting a diffuser hole inside the shelf, the shelf is made to emit light through the light source and the diffuser hole, so as to provide sufficient light for the fruits and vegetables placed on the shelf, avoid insufficient light for some fruits and vegetables due to mutual blocking between items, thereby improving the freshness time of fruits and vegetables, and can provide full space lighting inside the refrigerator, improving the user experience.

[0098] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0099] It should be noted that, in the embodiments of this application, "front side" refers to the side of the refrigerator facing the user when it is in normal use. "Rear side" refers to the side opposite to the front side, that is, the side of the refrigerator facing away from the user when it is in normal use. "Left side" refers to the side of the refrigerator located on the user's left when it is in normal use. "Right side" refers to the side of the refrigerator located on the user's right when it is in normal use.

[0100] Figure 1 and Figure 2 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, a refrigerator may include:

[0101] The refrigerator includes a housing 10, which may have a cooling compartment 110. The cooling compartment 110 may have a loading / unloading opening, through which a user can place items into or remove items from the cooling compartment 110. The refrigerator may also include a door 20, which is rotatably connected to the housing 10 to open or close the cooling compartment 110. The refrigerator may also include a refrigeration unit, which may be located within the housing 10, for providing cooling to the cooling compartment 110.

[0102] In some embodiments, the cabinet 10 may include an inner liner 120 and a outer shell 130. The inner liner 120 may be configured with a cooling compartment 110. The outer shell 130 may be connected to the outside of the inner liner 120 to form the appearance of the refrigerator. The cabinet 10 may also include a heat insulation layer, which may be disposed between the inner liner 120 and the outer shell 130. The heat insulation layer can insulate the cooling compartment 110 to minimize heat exchange between the cooling compartment 110 and the outside of the refrigerator, thereby helping to ensure the cooling effect of the refrigerator.

[0103] like Figure 1 As shown, the cabinet 10 may include a front wall 121 located on the front side. An access port may be located on the front side of the cabinet 10; for example, the access port may be formed on the front wall 121. Exemplarily, the front wall 121 may be the front wall of the cabinet shell 130 located on the front side of the refrigerator. Alternatively, the front wall 121 may include the front wall of the cabinet shell 130 located on the front side of the refrigerator, and the front wall of the inner liner 120 located on the front side of the refrigerator, the inner liner front wall being adjacent to the front wall of the cabinet shell.

[0104] The cabinet 10 may also include a rear wall 122 located at the rear of the refrigerator. The rear wall 122 may be disposed opposite to the front wall 121. For example, the rear wall 122 may be a side wall of the inner liner 120 located at the rear of the refrigerator.

[0105] The cabinet 10 may also include two side walls 123 located on the left and right sides of the refrigerator, respectively. The two side walls 123 may be arranged opposite to each other, and each side wall 123 may be connected to the front wall 121 and the rear wall 122. For example, the two side walls 123 may be the side walls located on the left and right sides of the inner liner 120 of the refrigerator, respectively.

[0106] The cabinet 10 may also include a top wall 124 located on the top side of the refrigerator. The top wall 124 may be connected to the rear wall 122, the front wall 121, and the two side walls 123. For example, the top wall 124 may be the top wall of the inner liner 120.

[0107] The cabinet 10 may also include a bottom wall 125 located on the bottom side of the refrigerator. The bottom wall 125 may be disposed opposite to the top wall 124. The bottom wall 125 may be connected to the rear wall 122, the front wall 121, and the two side walls 123. For example, the bottom wall 125 may be the bottom wall of the inner liner 120.

[0108] The top wall 124, the rear wall 122, the bottom wall 125, and the two side walls 123 of the box enclose the refrigeration chamber 110.

[0109] The number of refrigeration rooms 110 can be one or more. For example, such as... Figure 1As shown, there can be two refrigeration compartments 110. One refrigeration compartment 110 can be located in the upper part of the cabinet 10. The other refrigeration compartment 110 can be located in the lower part of the cabinet 10. For example, the refrigeration compartment 110 located in the upper part of the cabinet 10 can be configured as a refrigerator compartment. The two refrigeration compartments 110 located in the lower part of the cabinet 10 can be configured as freezer compartments.

[0110] It is understood that the number of refrigeration compartments 110 can be one, three, or more, and the refrigeration compartments 110 can be configured as refrigerator compartments or freezer compartments. In some possible implementations, the refrigeration compartments 110 can also be configured as variable temperature compartments with internal temperature variations, which will not be elaborated further in this application embodiment.

[0111] The door 20 can be rotatably connected to the housing 10 to close or open its corresponding refrigeration compartment 110. Each refrigeration compartment 110 can have one door 20. Each refrigeration compartment 110 can also have two doors 20 (e.g.,...). Figure 1 (As shown) or two or more door bodies 20, which will not be described in detail in the embodiments of this application.

[0112] A refrigeration unit can be installed inside the enclosure 10 to provide cooling capacity to the refrigerated compartment 110. Exemplarily, the refrigeration unit may include a compressor, condenser, capillary tube, and evaporator connected in a cycle. During operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor to generate high-temperature, low-pressure refrigerant liquid, which is then transported to the capillary tube. The capillary tube depressurizes the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the refrigerated compartment 110.

[0113] refer to Figure 1 and Figure 2 The refrigerator may also include a shelf assembly 30, which may include a shelf 310. The shelf 310 may be translucent; for example, the shelf 310 may be a glass shelf or a transparent plastic shelf. The shelf 310 is slidably disposed within the refrigeration compartment 110. The top of the shelf 310 has a placement surface for placing items.

[0114] The number of shelves installed in a refrigeration compartment 110 can be one or more. In the implementation where the number of shelves in the refrigeration compartment 110 is multiple, the multiple shelves can be arranged at intervals along the height direction Z of the refrigerator to improve the space utilization rate in the height direction Z of the refrigeration compartment 110.

[0115] refer to Figure 3 The shelf assembly 30 may also include a light source 320, which may be strip-shaped and may be disposed at the edge (also known as the end) of the shelf 310. Exemplarily, the light source 320 may be disposed at at least one of the following four edges: the edge of the shelf 310 away from the rear wall 122 of the box, the edge of the shelf 310 near the rear wall 122 of the box, and the edge of the shelf 310 near the side wall 123 of the box.

[0116] The light source 320 can emit light toward the shelf 310 to increase the brightness of the shelf 310, thereby improving the lighting effect on the refrigeration room 110, making it easier for users to identify the items on the shelf 310, and thus making it easier for users to take the target items.

[0117] In some possible implementations of the embodiments of this application, the light source 320 can be directly attached to the edge of the shelf 310.

[0118] refer to Figure 4 The shelf 310 may also include a plurality of light-diffusing components 311 disposed inside the shelf 310. The light-diffusing components 311 are used to scatter the light emitted by the light source 320 onto the surface of the shelf 310.

[0119] For example, the light source 320 emits light towards the shelf 310. When the light travels inside the shelf 310, it encounters the light-diffusing component 311 inside the shelf 310, causing diffuse reflection and scattering from the upper and lower surfaces of the shelf 310, thus emitting light from the upper and lower surfaces of the shelf 310. By providing illumination to the fruits and vegetables placed on the shelf 310 through the luminous shelf 310, the problem of insufficient light caused by mutual shading between fruits and vegetables can be effectively avoided, thereby improving the photo-preservation effect of fruits and vegetables.

[0120] In some possible implementations of the embodiments of this application, the light-diffusing component 311 can be arranged in the shelf 310 by laser engraving dots on the shelf 310.

[0121] In some embodiments, since photosynthesis is the basis of fruit and vegetable photosynthesis, insufficient light intensity will reduce the efficiency of photosynthesis, resulting in slow photosynthesis and poor preservation. To improve the preservation effect of fruits and vegetables, it is necessary to ensure the consistency and uniformity of the light intensity scattered from all positions on the surface of the shelf 310, so that fruits and vegetables stored in all positions of the shelf 310 can receive sufficient light intensity.

[0122] Because the intensity of light decreases with increasing propagation distance, when light-diffusing components 311 are installed in the shelf 310, the density of the light-diffusing components 311 arranged inside the shelf 310 is negatively correlated with the distance between the light sources, that is, as... Figure 4As shown, the closer the light-diffusing components 311 are to the light source 320, the sparser their arrangement. By deploying more light-diffusing components 311 in the shelf 310 at positions away from the light source 320, more components 311 diffusely reflect light in areas with weaker illumination, thus offsetting the light intensity attenuation caused by increased propagation distance. This results in higher consistency and uniformity of light intensity scattered from various positions on the shelf 310 surface, ensuring better preservation of fruits and vegetables. Simultaneously, the high consistency and uniformity of light intensity scattered from various positions on the shelf 310 surface (i.e., uniform light emission from the shelf) reduces the likelihood of inconsistent lighting in different locations within the refrigeration chamber 110, enhancing the aesthetic appeal of the lighting in the refrigeration chamber 110.

[0123] In some embodiments, such as Figure 5 As shown, the light source 320 can be composed of multiple spaced-apart LED beads 321, each of which can emit light of a different color. For example, the light emitted by the LED beads 321 can include red, blue, orange, green, purple, yellow, cyan, and other colors.

[0124] In some embodiments, the photosynthesis of fruits and vegetables primarily relies on chlorophyll and other accessory pigments, which have different absorption efficiencies for different wavelengths of light. For example, chlorophyll a mainly absorbs red light, while chlorophyll b mainly absorbs blue light. Therefore, to further enhance the photopreservation effect, the light source 320 includes LEDs with at least two different light emission colors. Through the synergistic effect of multiple light sources, a more comprehensive spectral environment can be provided for fruits and vegetables, thereby improving their preservation effect.

[0125] For example, the light source 320 may be composed of red LED beads 321 and blue LED beads 321, or the light source 320 may be composed of red LED beads 321, or blue LED beads 321 and purple LED beads 321. The embodiments of this application do not limit the color of the LED beads 321 included in the light source 320.

[0126] In some embodiments, since red and blue light have the greatest impact on photosynthesis, the light source includes red and blue LEDs arranged at intervals to enhance the effect of photocatalysis.

[0127] In some embodiments, taking the light source 320 as an example, which includes LEDs of two light-emitting colors, red and blue, the arrangement of the LEDs 321 in the light source 320 can be arbitrary. For example, red LEDs 321 and blue LEDs 321 can be arranged alternately, or two red LEDs 321 and one blue LED 321 can be arranged alternately, or two blue LEDs 321 and one red LED 321 can be arranged alternately, etc. The embodiments of this application do not limit the arrangement of the LEDs 321 in the light source 320.

[0128] In some embodiments, taking a light source 320 containing LEDs of both red and blue light colors as an example, based on the light reaction mechanism and spectral absorption characteristics of photosynthesis, adding some shorter wavelength blue light in addition to long-wavelength red light can improve the quantum efficiency of photosynthesis in fruits and vegetables. Therefore, when arranging the LEDs in the light source 320, adjacent LEDs 321 emit different colors. That is, red LEDs 321 and blue LEDs 321 in the light source 320 are arranged alternately. Through the complementary effect of adjacent two different colors of light, the overall efficiency of photosynthesis is improved, further enhancing the freshness preservation effect.

[0129] In some embodiments, when arranging the LED beads 321 in the light source 320, the spacing between the LED beads 321 should not be too large or too small. If the spacing is too large, the light intensity will be insufficient, and if the spacing is too small, the complementary effect of different colors of light will be reduced, thereby affecting the effect of light preservation.

[0130] In some embodiments, the spacing between the LEDs 321 is related to at least one of the size of two adjacent LEDs, the wavelength of light emitted by two adjacent LEDs, and the bandwidth. The size of an LED can refer to its diameter.

[0131] In some embodiments, the larger the size of two adjacent LEDs, the larger the spacing between them; and / or, the greater the wavelength difference between the light emitted by two adjacent LEDs, the larger the spacing between them; and / or, the greater the bandwidth difference between the light emitted by two adjacent LEDs, the larger the spacing between them.

[0132] In some embodiments, the larger the size of two adjacent LEDs and the greater the difference in the light bandwidth between two adjacent LEDs, the larger the spacing between two adjacent LEDs; and / or, the greater the difference in the light bandwidth between two adjacent LEDs and the greater the difference in the light wavelength between two adjacent LEDs, the larger the spacing between two adjacent LEDs; and / or, the larger the size of two adjacent LEDs and the greater the difference in the light wavelength between two adjacent LEDs, the larger the spacing between two adjacent LEDs.

[0133] For example, when the light source 320 includes two types of LEDs emitting different colors, and each LED is the same size, the distance d (in millimeters) between two adjacent LEDs can satisfy the following formula:

[0134]

[0135] Wherein, λ1 is the longer wavelength of two adjacent LED beads (unit: nanometers), λ2 is the shorter wavelength of two adjacent LED beads (unit: nanometers), D is the diameter of the LED bead, S1 is the bandwidth of light wave λ1, S2 is the bandwidth of light wave λ2, and a is a correction constant.

[0136] When the light source includes LED beads with two colors spaced apart, setting the spacing according to the above formula can maximize the light-based freshness preservation effect.

[0137] In some embodiments, if the light source includes LED beads of three or more colors, their spacing can be set based on experience, and this application embodiment does not limit this.

[0138] In some embodiments, when the light source is arranged with red and blue LEDs spaced apart, based on experimental and simulation verification, the optimal effect on preserving the freshness of fruits and vegetables is achieved when the spacing d between adjacent red and blue LEDs is within the range shown below.

[0139] 1.35 mm ≤ d, and d ≤ 2.35 mm.

[0140] For example, the spacing d between adjacent red and blue LED beads can be any value among 1.35 mm, 1.45 mm, 1.55 mm, 1.65 mm, 1.75 mm, 1.85 mm, 1.95 mm, 2.05 mm, 2.15 mm, 2.25 mm, and 2.35 mm, or any value between any two of the above spacings.

[0141] In some embodiments, reference Figure 6 In the direction parallel to the arrangement of the light source 320, the number of light-diffusing components 311 is the same as the number of lamp beads 321 (the number of light-diffusing components 311 in each column is the same as the number of lamp beads 321), and the spacing d1 between adjacent light-diffusing components 311 is equal.

[0142] In some embodiments, reference Figure 6 In the direction perpendicular to the arrangement of the light sources 320, the spacing d2 between adjacent diffuser components 311 is negatively correlated with the distance between the light sources 320; that is, the farther the diffuser component 311 is from the light source 320, the larger the spacing d2 between adjacent diffuser components. It should be understood that in the direction perpendicular to the arrangement of the light sources 320, the number of diffuser components 311 (the number of diffuser components 311 per row) is determined based on the size of the shelf 310 and the spacing d2 between adjacent diffuser components.

[0143] Optionally, the arrangement of the astigmatism component 311 in layer 310 can be as follows: Figure 6 As shown, the dots are arranged in a linear pattern. To enhance the aesthetics of the shelf lighting, the arrangement of the diffused light components 311 in the shelf 310 can present a specific pattern, such as a fruit and vegetable pattern.

[0144] In some embodiments, the relationship between light intensity and distance (the distance between the observation point and the light source) can be described by the inverse square law, that is, if the distance is doubled, the light intensity will decrease to one-quarter of the original, and if the distance is halved, the light intensity will increase to four times the original.

[0145] Therefore, when setting the astigmatism component 311, refer to Figure 7 In the scattering direction of the light source 320, the spacing between adjacent scattering components 311 decreases proportionally. For example, the spacing between the first and second columns of scattering components 311 away from the light source is d2, the spacing between the second and third columns of scattering components 311 away from the light source is 2*d2, and the spacing between the first and second columns of scattering components 311 away from the light source is 3*d2.

[0146] By proportionally reducing the spacing between the light-diffusing components 311, the uniformity of light intensity on the shelf can be effectively improved.

[0147] In some embodiments, reference Figure 7 The spacing d2 between adjacent diffuser components can be equal to the spacing d between two adjacent LEDs. For example, in the vertical direction of the light source 320, the spacing between the first and second columns of diffuser components 311 away from the light source is d, the spacing between the second and third columns of diffuser components 311 away from the light source is 2*d, and the spacing between the first and second columns of diffuser components 311 away from the light source is 3*d.

[0148] In some embodiments, reference Figure 7 The spacing d1 between adjacent diffuser components 311 can be equal to the spacing d between two adjacent LED beads. That is, in the parallel direction of the light source 320, the spacing between adjacent diffuser components 311 is d.

[0149] In some embodiments, in the parallel direction of the light source 320 arrangement, the position of the light-diffusing component 311 can be on the same horizontal line as the corresponding lamp bead 321. Optionally, the lamp bead 321 can also be positioned at any position between the two nearest light-diffusing components 311. By reasonably setting the positions of the light source and the light-diffusing structure, an optimal preservation environment can be provided for fruits and vegetables.

[0150] In some embodiments, the power of each LED 321 can be set based on actual needs; for example, the power of the red and blue LEDs can be set between 5 watts and 10 watts.

[0151] In some embodiments, the light-diffusing component 311 has a hole-like structure, such as a round hole, a square hole, or other hole-like structure.

[0152] In some embodiments, the light-diffusing component 311 is disposed inside the shelf 310. Generally speaking, in a refrigerator, the thickness of the shelf 310 is less than or equal to 5 mm. Since heavier items may be stored on the shelf 310, considering the load-bearing strength of the shelf 310, the aperture of the light-diffusing component 311 is less than or equal to 1 mm, and / or the aperture depth of the light-diffusing component is less than 5 mm.

[0153] In some embodiments, the aperture r of the astigmatism component is within the following range:

[0154] 0.3 mm ≤ r, and r ≤ 0.7 mm.

[0155] For example, the aperture r of the astigmatism component can be any value among 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, and 0.7 mm, or any value within any two of the above aperture ranges.

[0156] In some embodiments, the aperture depth h of the astigmatism component is within the following range:

[0157] 1 mm ≤ h, and r ≤ 3 mm.

[0158] For example, the aperture depth h of the astigmatism component can be any value among 1 mm, 1.5 mm, 2 mm, 2.5 mm, and 3 mm, or any value within any two of the above aperture depth ranges.

[0159] By setting appropriate aperture and depth of the light-diffusing component 311, the shelf 310 can have sufficient load-bearing strength while ensuring the effect of photosynthetic preservation.

[0160] In some embodiments, the surface of the shelf 310 may also be coated with a catalyst material, such as titanium dioxide, zinc oxide, silver nanoparticles, etc. When the catalyst material is irradiated by a light source 320 (e.g., red light, purple light, etc.), it can generate strong oxidizing ions to sterilize the refrigeration chamber 110.

[0161] In some embodiments, reference Figure 8 The light source 320 may also include a sterilization component 322, which is disposed between two adjacent lamp beads 321. After being powered on, the sterilization component 322 can sterilize the refrigeration chamber 110. For example, the sterilization component can be an ultraviolet lamp.

[0162] In some other possible implementations of the embodiments of this application, reference is made to Figure 9 and Figure 10The shelf may also include a shelf plate 312 and a mounting strip 313. The light-diffusing component 311 is disposed inside the shelf plate 312, and the mounting strip 313 is disposed at the edge of the shelf plate 312. The light source 320 may be disposed within the mounting strip 313. The mounting strip 313 can protect the light source 320 to reduce the possibility of damage to the light source 320.

[0163] For example, refer to Figure 11 The mounting strip 313 may have a channel structure 331, which may include a plug-in channel portion 334. At least a portion of the shelf 312 may be plugged into the plug-in channel portion 334 to assemble the light source 320 and the shelf 312 via the mounting strip 313.

[0164] refer to Figure 11 and Figure 12 The insertion channel portion 334 may have an upper channel wall and a lower channel wall, and the upper channel wall and / or the lower channel wall may be provided with a protrusion 337, which protrudes toward the shelf 312. For example, the protrusion 337 may be semi-cylindrical or hemispherical. The upper surface and / or lower surface of the shelf 312 abuts against the protrusion 337, which can reduce the gap between the shelf 312 and the insertion channel, thereby reducing the wobbling of the shelf 312 relative to the mounting strip 313.

[0165] The channel structure 331 may further include an optical channel portion 333. The light source 320 may be disposed within the optical channel portion 333. For example, see reference... Figure 12 A first limiting recess 336 may be constructed on the channel wall of the light channel portion 333, and a portion of the light source 320 is inserted into the first limiting recess 336 to fix the light source 320 within the mounting strip 313. The light channel portion 333 and the insertion channel portion 334 may be connected so that the light emitted by the light source 320 can be directed onto the shelf 312, thereby illuminating the shelf 312. By positioning the light source 320 at the edge of the shelf 312 through the mounting strip 313, the mounting strip 313 can shield and protect the light source 320, extending its service life and improving the refrigerator's aesthetics.

[0166] refer to Figure 12The sidewall of the light channel portion 333 may have a reflective curved surface 335, which is recessed in a direction away from the light channel portion 333. One end of the reflective curved surface 335 extends close to the insertion channel portion 334, and the other end extends close to the light source 320. The light emission direction of the light source 320 can be directed toward the reflective curved surface 335. The reflective curved surface 335 is used to reflect at least part of the light from the light source 320 and then obliquely direct it toward the end face 311 of the shelf 312. The oblique direction of the light toward the end face 311 of the shelf 312 means that the angle between the light and the end face 311 of the shelf 312 is greater than 0° and less than 90°, so that the light can be emitted from the upper and / or lower surfaces of the shelf 312 after it is directed toward the shelf 312. This reduces the light flux loss caused by the light emitting from the end face 311 of the shelf 312 when the light enters perpendicularly to the end face 311 of the shelf 312, thereby improving the utilization rate of light and the illumination effect on the objects above and / or below the shelf 312.

[0167] refer to Figure 11 and Figure 12 A light-diffusing element 332 can be provided within the channel structure 331. The light-diffusing element 332 can be a light-diffusing plate, a light-diffusing sheet, or other components that can reflect light; in the accompanying drawings, the light-diffusing element 332 is shown as a light-diffusing plate. The light-diffusing element 332 can be separated between the light channel portion 333 and the insertion channel portion 334. The plate surface of the light-diffusing element 332 can extend vertically or be tilted relative to the vertical direction. The light-diffusing element 332 can scatter the light emitted by the light source 320, and the scattered light is directed towards the end face 311 of the layer plate 312, making the light distribution towards the end face 311 of the layer plate 312 more uniform, thereby reducing glare and shadows and providing a soft and uniform lighting effect.

[0168] In some embodiments, the refrigerator may also include a main light source disposed on the top or side wall of the refrigerator for illuminating the refrigerator.

[0169] Based on the above embodiments, this application also provides a control method for a fresh-keeping refrigerator, which is applied to the fresh-keeping refrigerator shown in any of the above embodiments.

[0170] Figure 13 This is a flowchart illustrating the control method for a food-preserving refrigerator provided in an embodiment of this application, as shown below. Figure 13 As shown, it includes:

[0171] S1301. Detect the opening and closing status of the refrigerator's cooling compartment door.

[0172] The execution entity in this application embodiment can be the refrigerator controller, which controls the operation of the refrigerator.

[0173] In some embodiments, the refrigerator's cooling compartment includes an open state and a closed state. In the open state, the user can take or place food items inside the cooling compartment. The controller can detect the open / closed state of the cooling compartment using existing detection methods, which will not be elaborated here.

[0174] S1302. Based on the door opening / closing status, control the refrigerator's light source to emit light or stop emitting light.

[0175] In some embodiments, the refrigerator's light source may include a main light source for illuminating the refrigerator and light sources disposed in the shelves.

[0176] In some embodiments, S1302 may include the following sub-steps:

[0177] S1. After the controller detects that the refrigerator compartment is open, it can control the main light source of the refrigerator lighting to emit light, as well as the light source set in the shelf to emit light, so as to provide sufficient lighting for the refrigerator interior and make it easier for users to take out and put in food.

[0178] S2, after the controller detects that the refrigerator door is open for a preset time (e.g., 5 minutes), the controller can confirm that the refrigerator is in an abnormal open state, control the main light source of the refrigerator lighting to stop emitting light, and control the light source set in the shelf to stop emitting light, and issue an open door alarm.

[0179] S3. After the controller detects that the refrigerator compartment is closed, it can stop the main light source for refrigerator lighting and control the light sources installed on the shelves to illuminate, so that the refrigerator enters the freshness preservation mode. This mode allows the fruits and vegetables placed on the shelves to photosynthesize and preserve their freshness, thereby extending their shelf life. Entering the freshness preservation mode can mean controlling the LEDs in the light sources to illuminate in a preset manner, such as turning red and blue LEDs on or off according to a preset cycle and duration.

[0180] In some embodiments, the refrigerator further includes a food identification component (e.g., a camera), disposed within the refrigeration compartment and connected to the controller, for identifying food items stored on the shelves. Exemplarily, the food identification component may be disposed on the side wall, top, or surface of the shelves of the refrigerator; this application embodiment does not limit the placement of the food identification component.

[0181] In some embodiments, after the controller detects that the refrigeration compartment is closed, it can determine whether to control the light source in the corresponding shelf to emit light and enter the freshness preservation mode by following the steps below.

[0182] S31. The controller can control the food identification component to identify the food on the shelf and identify whether there is any food on the shelf that needs to be photosynthesized for preservation.

[0183] The controller can compare the food identification results of the food identification component with preset foods that require light and preservation. If the identification results include at least one preset food that requires light and preservation, then it is determined that there are foods that need photosynthetic preservation. It should be understood that the food identification component can identify the foods on the shelf in accordance with existing technologies, and will not be described in detail here.

[0184] S32. If present, control the light source in the corresponding shelf to emit light and enter the freshness preservation mode.

[0185] S33. If it does not exist, control the light source in the corresponding shelf to stop emitting light in order to reduce the power consumption of the refrigerator.

[0186] The control method for the fresh-keeping refrigerator provided in this application embodiment not only turns on the main light when the user opens the cooling compartment, but also simultaneously turns on the light sources installed on the shelves. This not only enhances the sensory experience of refrigeration lighting, but also illuminates food while shielding corners, making it more convenient for the user to retrieve and place ingredients. After the user closes the cooling compartment, the system determines whether to enter the fresh-keeping mode based on the identification results of the food. This not only allows for photosynthetic freshness preservation of the food, extending its shelf life, but also reduces the refrigerator's power consumption.
