[0050] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0051] In related technologies, refrigerator crisper drawers typically use a single wavelength of light source for illumination. However, in actual use, users often store a variety of fruits and vegetables together in the same drawer. Different fruits and vegetables have different light requirements. For example, vegetables usually need red light to promote growth and maintain color, while fruits are more suitable for blue light to delay ripening and decay. This results in the inability to meet the differentiated light requirements of different types of fruits and vegetables, thus affecting the refrigerator's preservation effect.

[0052] In view of this, in one aspect of the present disclosure, a refrigerator drawer is provided that can improve the preservation effect.

[0053] Figure 1 These are structural schematic diagrams of some embodiments of a refrigerator drawer according to the present disclosure. Figure 2 These are schematic diagrams of the structure of refrigerator drawers according to other embodiments of the present disclosure. Figure 3 These are optical path projection diagrams of some embodiments of the refrigerator drawer according to this disclosure. Figure 3 The dashed line in the image represents the optical path provided by light source 2. (Reference) Figures 1-3 The refrigerator drawer includes the drawer body 1, the light source 2, and the filter device 3.

[0054] The bottom of the drawer body 1 has multiple storage areas 10, the areas of which may be equal or unequal, and each storage area 10 is configured to store one type of fruit or vegetable. A light source 2 is located at the top of the drawer body 1, near the center of the top, and is configured to provide white light; there may be one or more light sources 2.

[0055] The filter device 3 is located inside the drawer body 1 and in the light path of the light source 2, and is configured to provide light of multiple colors and / or multiple light intensities to each storage area 10.

[0056] The filter device 3 is located near the top of the drawer body 1, including but not limited to being retractable, slidable or rotatable relative to the top of the drawer body 1, so that the user can flexibly adjust the position of the filter element inside the filter device 3 according to the light requirements of each storage area 10, thereby providing light of matching wavelength and / or intensity to different storage areas 10.

[0057] The refrigerator drawer may also be equipped with an image acquisition device 4, which is configured to capture images of items stored inside the drawer body 1. The image acquisition device 4 includes one or more cameras and may be located, but is not limited to, at the top or other positions inside the drawer body 1, to capture images of fruits and vegetables stored inside the drawer body 1. The image acquisition device 4 is placed near a light source 2 and a filter device 3 to improve installation convenience.

[0058] The user can determine the type of items stored in each storage area 10 based on the images captured by the image acquisition device 4, and determine the corresponding light color and intensity based on the type of items stored in each storage area 10. Then, the filter device 3 is adjusted to provide each storage area 10 with light of a color and / or intensity corresponding to the type of items stored. The types of items stored in the storage area 10 include, but are not limited to, varieties of fruits and / or vegetables.

[0059] In this embodiment, by setting up a filter device 3 to provide light of multiple colors and / or multiple light intensities to each storage area 10, the diverse preservation needs of different kinds of fruits and vegetables in the refrigerator drawer can be met, thereby improving the preservation effect of the refrigerator drawer.

[0060] Figure 4 This is a schematic diagram of the structure of a first or second filter assembly according to some embodiments of a refrigerator drawer of this disclosure. Figure 4 Only the arrangement of the first filter 311 and the second filter 321 is shown; the shape of the first filter 311 and the second filter 321 is not limited. Figure 5 This is a schematic diagram of the storage area structure according to some embodiments of a refrigerator drawer of this disclosure, with reference to... Figures 1-5 In some embodiments, the filtering device 3 includes a first filtering component 31 and a second filtering component 32 arranged along a first direction parallel to the vertical direction. The first filtering component 31 includes a plurality of first filter sheets 311 configured to allow light of a first color to pass through. The second filtering component 32 includes a plurality of second filter sheets 321 configured to allow light of a second color to pass through. The first color and the second color are different.

[0061] Each first filter 311 and each second filter 321 corresponds one-to-one with each storage area 10, and each first filter 311 and each second filter 321 is configured to extend and retract relative to the drawer body 1. When the first filter 311 or the second filter 321 is extended, the colored area 30a of the first filter 311 or the second filter 321 is located in the light path projected by the light source 2 onto the storage area 10.

[0062] The user can extend the first filter 311 or the second filter 321 at the corresponding position according to the color of light required for each storage area 10, so that the colored area 30a of the first filter 311 or the second filter 321 is located in the light path projected by the light source 2 to the storage area 10, so as to project the required light to different storage areas 10.

[0063] The first color is, but is not limited to, red or blue, and the second color is, but is not limited to, red or blue. Each first filter 311 has a colored region 30a that allows light of the first color to pass through, while the remaining regions are light-transmitting regions 30b. The area of ​​the colored region 30a of each first filter 311 is less than or equal to the total area of ​​the first filter 311. Each second filter 321 has a colored region 30a that allows light of the second color to pass through, while the remaining regions are light-transmitting regions 30b. The area of ​​the colored region 30a of each second filter 321 is less than or equal to the total area of ​​the second filter 321.

[0064] Figure 4 The diagram shows either a first filter component 31 or a second filter component 32. The first filter component 31 and the second filter component 32 may be arranged adjacently or alternately along a first direction. The first filter elements 311 of each first filter component 31 are arranged sequentially along the first direction and / or the second direction, and the second filter elements 321 of each second filter component 32 are arranged sequentially along the first direction and / or the second direction. The number of first filter elements 311 and second filter elements 321 can be adjusted according to actual needs.

[0065] Each storage area 10 corresponds to a first filter 311 and a second filter 321. When the storage area 10 requires illumination of the first color, the user can adjust the filter device 3 so that the corresponding first filter 311 is in an extended state and the corresponding second filter 321 is in a retracted state. The light emitted by the light source passes through the colored area 30a of the first filter 311 and is projected onto the storage area 10, providing the storage area 10 with illumination of the first color. When the storage area 10 requires illumination of the second color, the user can adjust the filter device 3 so that the corresponding first filter 311 is in a retracted state and the corresponding second filter 321 is in an extended state. The light emitted by the light source passes through the colored area 30a of the second filter 321 and is projected onto the storage area 10, providing the storage area 10 with illumination of the second color.

[0066] In this embodiment, the first filter component 31 and the second filter component 32 are arranged along the first direction, and the first filter component 31 has a first filter 311 corresponding to each storage area 10, and the second filter component 32 has a second filter 321 corresponding to each storage area 10. This allows the white light provided by the light source 2 to be projected onto the bottom of the drawer body 1 through the colored area 30a of each first filter 311 and each second filter 321, so that the projection can form a one-to-one correspondence with each storage area 10, and each storage area 10 can project multiple colors of light.

[0067] In some embodiments, the filtering device 3 includes a plurality of filtering components corresponding one-to-one with each storage area 10. Each filtering component includes a first filter 311 and a second filter 321 arranged along a first direction parallel to the vertical direction. The first filter 311 is configured to allow light of a first color to pass through, and the second filter 321 is configured to allow light of a second color to pass through. The first color and the second color are different.

[0068] Each first filter 311 and each second filter 321 are configured to extend or retract relative to the drawer body 1. When the first filter 311 or the second filter 321 is extended, the colored area 30a of the first filter 311 or the second filter 321 is located in the light path projected by the light source 2 onto the storage area 10.

[0069] The user can extend the first filter 311 or the second filter 321 at the corresponding position according to the color of light required for each storage area 10, and make the colored area 30a of the first filter 311 or the second filter 321 located in the light path projected by the light source 2 onto the storage area 10.

[0070] The first color is, but is not limited to, red or blue, and the second color is, but is not limited to, red or blue. Each first filter 311 has a colored region 30a that allows light of the first color to pass through, while the remaining regions are light-transmitting regions 30b. The area of ​​the colored region 30a of each first filter 311 is less than or equal to the total area of ​​the first filter 311. Each second filter 321 has a colored region 30a that allows light of the second color to pass through, while the remaining regions are light-transmitting regions 30b. The area of ​​the colored region 30a of each second filter 321 is less than or equal to the total area of ​​the second filter 321.

[0071] The first filter 311 and the second filter 321 of each filter component are arranged adjacent to or at intervals along the first direction. Multiple filter components are arranged sequentially along the first direction and / or the second direction. The number of the first filter 311 and the second filter 321 can be adjusted according to actual needs.

[0072] Each storage area 10 corresponds to a first filter 311 and a second filter 321. When the storage area 10 requires illumination of the first color, the user can pull out the corresponding first filter 311 and push the corresponding second filter 321 back into the drawer body 1. The light emitted by the light source 2 passes through the colored area 30a of the first filter 311 and is projected onto the storage area 10, providing the storage area 10 with illumination of the first color. When the storage area 10 requires illumination of the second color, the user can push the corresponding first filter 311 back into the drawer body 1 and pull out the corresponding second filter 321. The light emitted by the light source 2 passes through the colored area 30a of the second filter 321 and is projected onto the storage area 10, providing the storage area 10 with illumination of the second color.

[0073] In this embodiment, the first filter 311 and the second filter 321 of each filter component are arranged along the first direction, and each storage area 10 is respectively associated with the first filter 311 and the second filter 321, so that the white light provided by the light source 2 can be projected onto the bottom of the drawer body 1 through the colored area 30a of each first filter 311 and each second filter 321 to form a one-to-one correspondence with each storage area 10, so that each storage area 10 can project multiple colors of light.

[0074] Figure 6A This is a schematic diagram of the structure of a first or second filter element according to some embodiments of a refrigerator drawer of this disclosure. Figure 6B This is a schematic diagram of the structure of a first or second filter element according to some other embodiments of a refrigerator drawer of this disclosure. Figure 6C This is a schematic diagram of the structure of a first or second filter element according to some embodiments of a refrigerator drawer of the present disclosure, with reference to... Figures 1-6CIn some embodiments, a plurality of first filter sheets 311 are arranged in M ​​layers along a first direction and in N columns along a second direction, a plurality of second filter sheets 321 are arranged in M ​​layers along the first direction and in N columns along the second direction, and the storage area 10 is arranged in M ​​rows along a third direction and in N columns along the second direction.

[0075] Each first filter 311 and second filter 321 has a colored area 30a and a light-transmitting area 30b. With the first filter 311 and second filter 321 extended, each layer of colored areas 30a in the same column is staggered along a third direction, so that the projection of light passing through each layer of colored areas 30a in the same column onto the bottom of the drawer body 1 corresponds one-to-one with each row of storage areas 10 located in the same column. The second direction is parallel to the horizontal direction, and the third direction is perpendicular to both the first and second directions.

[0076] Figure 5 It shows 10 storage areas with M rows and N columns. Figure 5 Each square area in the filter is a storage area 10. With the second direction as the horizontal coordinate and the third direction as the vertical coordinate, each storage area 10 can correspond to a coordinate position (M, N). Correspondingly, the corresponding positions of the first filter 311 and the second filter 321 in the filter device 3 are the Mth layer and the Nth column.

[0077] For example, when the filtering device 3 includes a first filtering component 31 and a second filtering component 32, the storage area 10 with coordinates (M, N) corresponds to the first filter 311 in the Mth layer and Nth column of the first filter 311 array of the first filter 311 of the first filtering component 31 and the second filter 321 in the Mth layer and Nth column of the second filter 321 array of the second filtering component 32.

[0078] When the filtering device 3 includes multiple filtering components that correspond one-to-one with each storage area 10, the first filter 311 and the second filter 321 of the multiple filtering component array corresponding to the storage area 10 at coordinate position (M, N) are located in the Mth layer and the Nth column.

[0079] Figure 6A , 6B Figure 6C shows the distribution of the colored region 30a and the light-transmitting region 30b in the first filter 311 or the second filter 321 of the first, second and M layers of a certain column. Since the light path of the light source 2 is conical, in order to make each first filter 311 and the second filter 321 correspond one-to-one with each row of storage area 10, the colored region 30a of each first filter 311 and the second filter 321 is set to be staggered along the third direction to avoid interference and stacking of the light path after filtering by each first filter 311 and the second filter 321.

[0080] For example, each first filter 311 and second filter 321 is divided into M regions along a third direction, numbered sequentially as region 1, region 2, region 3, ..., region M. One of the M regions is a colored region 30a, and the remaining M-1 regions are light-transmitting regions. The light-transmitting regions allow any light to pass through, while the colored regions 30a only allow the first color or the second color to pass through. The colored region 30a of the first filter 311 in the first layer is located in region 1, closest to the inside of the refrigerator drawer; the colored region 30a of the first filter 311 in the second layer is located in region 2; and the colored region 30a of the first filter 311 in the Mth layer is located in region M, closest to the opening of the refrigerator drawer.

[0081] The number of filter devices 3 may include, but is not limited to, one or more, and the specific number and distribution can be adjusted according to actual conditions. When there are multiple filter devices 3, the multiple filter devices 3 correspond one-to-one with the M rows and N columns of storage areas 10 at the bottom of the drawer body 1. For example, Figure 2 Two filtering devices 3 are shown arranged along a third direction. One filtering device 3 corresponds to the storage area 10 at the bottom of the drawer body 1, from the 1st row and Nth column to the / 2nd row and Nth column. The other filtering device 3 corresponds to the storage area 10 at the bottom of the drawer body 1, from the M / 2+1th row and Nth column to the Mth row and Nth column.

[0082] In this embodiment, by setting each layer of colored area 30a in the same column to be staggered along the third direction, interference and stacking of the light paths after filtering by the first filter 311 and the second filter 321 in each layer can be avoided, so that the light provided by each first filter 311 and the second filter 321 can form a precise correspondence with each storage area 10.

[0083] Figure 7 This is a top view of a first or second filter located in the same column according to some embodiments of a refrigerator drawer of this disclosure, with reference to... Figure 7 In some embodiments, the width of each first filter 311 and second filter 321 in the same column gradually decreases from the middle layer to both ends along the second direction; and / or the width of each colored region 30a in the same column gradually decreases from the middle layer to both ends along the third direction. The width variation of each first filter 311 and second filter 321 in the same column along the second direction is not shown in the figure.

[0084] Since the light path of the light source 2 is conical, in order to make the light provided by each first filter 311 and second filter 321 present a more accurate and reliable correspondence with each storage area 10, the width of the first filter 311 and second filter 321 located in the first layer and the Mth layer along the second direction is set to be smaller than the area of ​​the width of the first filter 311 and second filter 321 located in the M / 2th layer along the second direction.

[0085] Figure 7 This shows a top view with the first filter 311 or the second filter 321 of each layer in the same column extended, from Figure 7 The colored areas 30a of all layers can be seen. Since the light path of the light source 2 is conical, in order to make the light provided by each colored area 30a correspond more accurately and reliably to each storage area 10, the width of the colored area 30a of the first filter 311 located in the first layer and the Mth layer along the third direction is smaller than the width of the colored area 30a of the first filter 311 located in the M / 2th layer along the third direction.

[0086] In this embodiment, in order to enable the light provided by each first filter 311 and second filter 321 to present a more accurate and reliable correspondence with each storage area 10, the width of each layer of first filter 311 and second filter 321 in the same column gradually decreases from the middle layer to both ends along the second direction and / or the width of each layer of colored area 30a in the same column gradually decreases from the middle layer to both ends along the third direction. So that when the multiple layers of first filter 311 or second filter 321 in the same column need to extend, each layer of first filter 311 and second filter 321 can accurately project the required light into the corresponding storage area 10.

[0087] In some embodiments, the filtering device 3 further includes a neutral filtering component having a plurality of neutral filter sheets corresponding one-to-one with each storage area 10. The neutral filter sheets have multi-layered filtering elements that are retractably disposed relative to the drawer body 1, and the number of neutral filter sheets, first filter sheet 311 and second filter sheet 321 are equal.

[0088] The neutral density filter is configured to adjust the light intensity of the transmitted light. When the neutral density filter is thicker, the light intensity allowed to pass through is lower, and when the neutral density filter is thinner, the light intensity allowed to pass through is higher.

[0089] Users can adjust the thickness of the neutral filter by adjusting the expansion and contraction of each filter element in the neutral filter according to the light intensity required for the items stored in each storage area 10.

[0090] The thickness of the neutral filter can be adjusted by adjusting the number of layers of multi-layered filter elements extending from each neutral filter, thereby adjusting the light intensity supplied to the storage area 10.

[0091] For example, if storage area 10 requires lower light intensity, the user can reduce the thickness of the neutral density filter at the corresponding position of storage area 10, that is, reduce the number of layers of multi-layer filter elements extending from the neutral density filter.

[0092] In this embodiment, by setting a neutral filter component, the light intensity provided to the storage area 10 can be adjusted, thereby improving the preservation effect of each type of fruit and vegetable stored in each area of ​​the refrigerator drawer.

[0093] In some embodiments, each neutral filter is arranged along a first direction with a corresponding first filter and second filter, where corresponding refers to the neutral filter, first filter and second filter corresponding to the same storage area 10.

[0094] When the filtering device 3 includes a first filtering component 31 and a second filtering component 32, a neutral filtering component is disposed adjacent to the first filtering component 31 and / or the second filtering component 32 along a first direction. The neutral filtering component can be arranged in any order with the first filtering component 31 and the second filtering component 32 along the first direction. Since the neutral filter, the first filter 311, and the second filter 321 are very thin, the arrangement order of the neutral filter, the first filter 311, and the second filter 321 along the first direction affects the projection effect.

[0095] When the filtering device 3 includes multiple filtering components corresponding one-to-one with each storage area 10, each filtering component may include a neutral filter, a first filter 311, and a second filter 321. Each neutral filter is arranged adjacent to the first filter 311 and / or the second filter 321 along a first direction, and the neutral filter, the first filter 311, and the second filter 321 are arranged in any order along the first direction. Since the neutral filter, the first filter 311, and the second filter 321 are very thin, the arrangement order of the neutral filter, the first filter 311, and the second filter 321 along the first direction affects the projection effect.

[0096] Furthermore, each neutral filter also includes a neutral-colored area and a light-transmitting area, and in the extended state of the neutral filter, each layer of neutral-colored areas in the same column is staggered in the third direction so that the projection of neutral light allowed to pass through each layer of neutral-colored areas in the same column onto the bottom of the drawer body 1 corresponds one-to-one with each row of storage areas 10 in the same column.

[0097] For example, each neutral density filter is divided into M regions along a third direction, numbered sequentially as region 1, region 2, region 3, ..., region M. One of the M regions is a neutral-colored region, and the remaining M-1 regions are light-transmitting regions. The light-transmitting regions allow any light to pass through, while the neutral-colored regions only allow neutral colors to pass through. The neutral-colored region of the neutral density filter in the first layer is located in region 1, closest to the inside of the refrigerator drawer; the neutral-colored region of the neutral density filter in the second layer is located in region 2; and the neutral-colored region of the neutral density filter in the Mth layer is located in region M, closest to the opening of the refrigerator drawer.

[0098] In this embodiment, by arranging the neutral filter component adjacent to the first filter component 31 and / or the second filter component 32 along the first direction, or by arranging each neutral filter sheet adjacent to the first filter sheet 311 and / or the second filter sheet 321 along the first direction, each neutral filter sheet can form a one-to-one correspondence with each storage area 10.

[0099] refer to Figure 1 and Figure 2 In some embodiments, the top of the drawer body 1 has a mounting groove 11, and the filter device 3 is configured to extend and retract relative to the mounting groove 11 in the horizontal direction.

[0100] In this embodiment, by providing an installation slot 11 on the top of the drawer body 1 to accommodate the filter device 3, the first filter 311 and the second filter 321 of the filter device 3 are completely accommodated in the installation slot 11 when they are in the retracted state. This will not interfere with the image acquisition operation of the image acquisition device 4, nor will it affect the user's storage of items. When the storage area 10 has corresponding lighting requirements, the user can push the first filter 311 and the second filter 321 out of the installation slot 11 for convenient and flexible operation.

[0101] refer to Figure 1 and Figure 2 In some embodiments, the refrigerator drawer also includes a humidity regulating device 6, which is disposed on the top of the drawer body 1, has a moisture-permeable membrane, and is configured to regulate the humidity inside the drawer body 1.

[0102] The number of humidity regulating devices 6 can be one or more. The humidity regulating device 6 may include a moisture-permeable membrane groove. The moisture-permeable membrane is clipped into the moisture-permeable membrane groove through a mask to regulate the humidity in the room. It can keep the humidity in the room stable within 92%-97% to prevent condensation from occurring and causing the stored food to rot.

[0103] In this embodiment, by setting the humidity regulating device 6 and the filter device 3 together, the humidity in the room is maintained, which can further improve the preservation ability of the refrigerator drawer and keep the fruits and vegetables in a relatively fresh state.

[0104] In another aspect of this disclosure, a refrigerator is provided, including a refrigerator drawer as described in any of the above embodiments.

[0105] In this embodiment, the refrigerator can provide light of various colors and intensities into the compartment to meet diverse preservation needs and achieve better preservation results.
