Description

Technical Field

[0001] This application relates to refrigerator technology. More specifically, it relates to a refrigerator. Background Technology

[0002] The photosynthetic preservation function of refrigerators is becoming increasingly well-known to consumers. The refrigerator simulates the light in the natural environment to promote weak photosynthesis in fruits and vegetables, thereby slowing down their spoilage and achieving better preservation. This effect has been recognized by consumers in practical applications.

[0003] Current photosynthetic preservation refrigerators all use light-emitting devices to emit fixed or time-varying light waves to uniformly irradiate all vegetables and fruits stored in the refrigerator compartment, causing them to undergo photosynthesis and achieving a preservation effect. However, different vegetables and fruits have different light requirements. For example, fungi such as mushrooms and wood ear mushrooms do not need light; lettuce, pea sprouts, and radishes are not suitable for strong light, as strong light will affect their taste (pea sprouts will produce more fiber under strong light); cucumbers, tomatoes, green peppers, apples, etc. have high light requirements and can better retain their nutrients under strong light.

[0004] However, the aforementioned method of uniform lighting inside the refrigerator is clearly insufficient to meet users' needs for preserving various fruits and vegetables. Summary of the Invention

[0005] This application provides a refrigerator that can meet users' needs for storing and preserving various fruits and vegetables.

[0006] In a first aspect, embodiments of this application provide a refrigerator, comprising:

[0007] A housing, wherein at least one compartment is defined inside the housing, and an opening is provided on one side of the housing;

[0008] A door is provided at the opening, and one side of the door is hinged to one side of the opening;

[0009] Shelves are provided in the room, and the shelves and the inner wall of the box together define multiple storage areas for placing food ingredients;

[0010] A lighting component is disposed in the room, the lighting component is used to emit light waves covering multiple storage areas, and at least one of the wavelength and light intensity of the light waves covering each storage area is different;

[0011] An image recognition device is installed in the room, and the image recognition device is used to identify the types of food stored in the multiple storage areas;

[0012] The controller, electrically connected to both the illumination component and the image recognition device, is configured to:

[0013] Obtain the types of ingredients in the storage area and the actual storage area of ​​the ingredients;

[0014] The preset storage area for the ingredients is matched according to the type of ingredients;

[0015] Determine whether the preset storage area is the same as the actual storage area;

[0016] If not, prompt the user to place the ingredients back into the preset storage area.

[0017] The refrigerator provided in this application embodiment has multiple storage zones, each with different preservation conditions. Users can store food in suitable zones according to its characteristics, thereby extending its shelf life and reducing nutrient loss. Secondly, through the combination of an image recognition device and a controller, the refrigerator can automatically identify the types of food in the storage zones and intelligently store them according to preset preservation conditions. This not only improves the refrigerator's ease of use but also better meets users' preservation needs for different foods. Furthermore, when a user places food in an unsuitable storage zone, the controller can promptly prompt the user to reposition the food. This prompting function effectively prevents food spoilage due to improper storage, enhancing the user experience. Compared to existing technologies, the refrigerator in this application embodiment can emit light waves of different wavelengths and intensities for adaptive storage of different types of food. The refrigerator can intelligently identify food and manage its storage rationally, allowing users to better plan their food usage and reduce waste caused by spoilage.

[0018] In some embodiments of this application, the storage area located at the top of the box is designated as a first preservation area, the storage area located at the bottom of the box is designated as a second preservation area, and the storage area located between the first preservation area and the second preservation area is designated as a third preservation area.

[0019] The light intensity of the light waves covering the first preservation area, the third preservation area, and the second preservation area gradually increases;

[0020] And / or, the wavelength range of the light waves covering the first preservation area, the third preservation area and the second preservation area gradually increases.

[0021] In this way, by rationally allocating light intensity according to the light requirements of different ingredients, the freshness time of the ingredients can be extended to the maximum extent and their nutritional components can be preserved. By dividing the interior of the refrigerator into multiple preservation zones and setting different wavelengths of light conditions, the preservation needs of different ingredients can be better met, thereby extending their freshness time and reducing nutrient loss.

[0022] In some embodiments of this application, the third preservation area further includes a low preservation area and a high preservation area. The light intensity of the light wave covering the first preservation area is a, the light intensity of the light wave covering the second preservation area is b, the light intensity of the light wave covering the low preservation area is c, and the light intensity of the light wave covering the high preservation area is d. The relationship between a, b, c, and d is as follows:

[0023] a < c < d < b, a ≥ 0 and b, c, d > 0.

[0024] In this way, multiple preservation zones with tiered light intensity distribution can be created based on the different characteristics of the ingredients, thus meeting the preservation needs of various foods. Through image recognition, the refrigerator can identify the placement of the food; if the user places food in an unsuitable area, the refrigerator will promptly prompt the user to reposition it, thereby ensuring optimal preservation.

[0025] In some embodiments of this application, the third preservation area further includes a low preservation area and a high preservation area;

[0026] The light waves emitted by the light-emitting component do not cover the first preservation area;

[0027] The light waves covering the low-preservation zone include blue light with a wavelength range of 420nm-480nm and red light with a wavelength range of 620nm-670nm;

[0028] The light waves covering the high-preservation zone include blue light with a wavelength range of 420nm-480nm, red light with a wavelength range of 620nm-670nm, and white light with a wavelength range of 380nm-760nm.

[0029] The light waves covering the second preservation area include violet light with a wavelength range of 200nm-420nm, blue light with a wavelength range of 420nm-480nm, red light with a wavelength range of 620nm-670nm, white light with a wavelength range of 380nm-760nm, and near-infrared light with a wavelength range of 800nm-1100nm.

[0030] In this way, multiple preservation zones with different wavelength ranges can be formed according to the different characteristics of the ingredients, thus meeting the preservation needs of different ingredients. Through image recognition devices, the placement position of the ingredients can be identified. If the user places the ingredients in an unsuitable area, the refrigerator will promptly prompt the user to reposition them, thereby ensuring the best preservation effect.

[0031] In some embodiments of this application, the illumination component includes a plurality of illumination elements, and the plurality of illumination elements are located one-to-one in the second preservation area, the high preservation area and the low preservation area;

[0032] or,

[0033] The light-emitting component is located in the second preservation area. The second preservation area, the high preservation area, and the low preservation area are all covered by light waves emitted by the light-emitting component. Filter layers are provided between the second preservation area and the high preservation area, between the high preservation area and the low preservation area, and between the low preservation area and the first preservation area.

[0034] The filter layer is configured to block some wavelengths of light and reduce the light intensity of the light waves.

[0035] This allows for precise control of lighting conditions in each area, ensuring that food in each storage zone receives optimal lighting, thereby extending its shelf life and reducing nutrient loss.

[0036] In some embodiments of this application, the controller is further configured to:

[0037] Determine whether the preset storage area is the first preservation area;

[0038] If not, then determine whether the actual storage area is the first preservation area;

[0039] If so, prompt the user to remove the food from the first preservation area and place it back in the preset storage area.

[0040] In this way, when the controller determines that food belonging to the first preservation zone is placed in its storage area, it will prompt the user to correct the incorrect placement behavior in a timely manner, so as to avoid food spoilage due to misplacement.

[0041] In some embodiments of this application, the controller is further configured to:

[0042] Determine whether the preset storage area is the first preservation area;

[0043] If so, determine whether the actual storage area is the first preservation area;

[0044] If not, prompt the user to remove the food from the actual storage area and place it back in the first preservation area.

[0045] In this way, if the controller determines that food that does not belong to the first freshness zone has been placed in the first freshness zone, it will prompt the user to remove the food from the first freshness zone and place it back. This can promptly remind the user to correct the incorrect placement behavior and avoid food spoilage due to misplacement.

[0046] In some embodiments of this application, the controller is further configured to:

[0047] Determine whether the preset storage area is the second preservation area;

[0048] If so, determine whether the actual storage area is the third preservation area;

[0049] If so, it is recommended that the user remove the food from the actual storage area and place it back in the second preservation area.

[0050] In this way, if the controller determines that the food belonging to the second preservation area has been placed in the third preservation area, it will prompt the user to remove the food and put it back in the second preservation area. This can promptly remind the user to correct the incorrect placement behavior and avoid food spoilage due to misplacement.

[0051] In some embodiments of this application, a humidification module is further provided in the second preservation area, and the humidification module is used to adjust the humidity of the second preservation area;

[0052] And / or,

[0053] At least one of the housing and the door is provided with a sensor switch, the sensor switch being electrically connected to the lighting component; the sensor switch is used to obtain the distance between the door and the housing; the controller is further configured to:

[0054] Determine whether the refrigerator is sealed based on the distance between the door and the cabinet.

[0055] If not, control the illumination component to emit white light with a wavelength range of 380nm-760nm.

[0056] so,

[0057] Secondly, embodiments of this application also provide a refrigerator, including a cabinet, a door, shelves, an image recognition device, and a controller.

[0058] The enclosure has at least one compartment, and an opening is provided on one side of the enclosure. A door is located at the opening, and one side of the door is hinged to one side of the opening. The shelves, the lighting components, and the image recognition device are all located within the compartment.

[0059] The shelf and the inner wall of the box together define a plurality of storage areas for placing food ingredients. The image recognition device is used to identify the types of food ingredients stored in the plurality of storage areas. The lighting component is used to emit light waves covering the plurality of storage areas. At least one of the wavelength and light intensity of the light waves covering each of the storage areas is different.

[0060] The controller, electrically connected to both the illumination component and the image recognition device, is configured to:

[0061] Obtain the types of ingredients in the storage area and the actual storage area of ​​the ingredients;

[0062] The preset storage area for the ingredients is matched according to the type of ingredients;

[0063] Determine whether the preset storage area is the same as the actual storage area;

[0064] If not, prompt the user to place the ingredients back into the preset storage area.

[0065] The refrigerator provided in this application embodiment has multiple storage zones, each with different preservation conditions. Users can store food in suitable zones according to its characteristics, thereby extending its shelf life and reducing nutrient loss. Secondly, through the combination of an image recognition device and a controller, the refrigerator can automatically identify the types of food in the storage zones and intelligently store them according to preset preservation conditions. This not only improves the refrigerator's ease of use but also better meets users' preservation needs for different foods. Furthermore, when a user places food in an unsuitable storage zone, the controller can promptly prompt the user to reposition the food. This prompting function effectively prevents food spoilage due to improper storage, enhancing the user experience. Compared to existing technologies, the refrigerator in this application embodiment can emit light waves of different wavelengths and intensities for adaptive storage of different types of food. The refrigerator can intelligently identify food and manage its storage rationally, allowing users to better plan their food usage and reduce waste caused by spoilage. Attached Figure Description

[0081] Related technologies include patent application number CN200610104369.2, entitled "A Refrigerator with Light-Based Preservation Function and Its Implementation Method," which discloses a refrigerator with a light-based preservation function. A light-emitting device is installed in the fruit and vegetable compartment of the refrigerator's cold storage compartment. This device emits light waves whose wavelength and intensity vary over time, with the wavelength ranging from 300 nanometers to 800 nanometers, and the intensity variation mimicking the changing patterns of sunlight. The light-emitting device includes a power supply unit, a control unit, cables, and a light source unit. The light source uses a specially designed 4-pin light-emitting diode to emit light waves with variable wavelengths. Five light waves beneficial to fruit and vegetable growth are synthesized to create a synthetic light source. The light source is controlled by the control unit to sequentially change the emitted wavelength and intensity. This invention can provide simulated sunlight illumination for fruits and vegetables placed in the refrigerator, achieving the conditions required for photosynthesis, preventing nutrient loss, and achieving fruit and vegetable preservation.

[0082] However, the refrigerators mentioned above use light emitting devices to emit fixed or time-varying light waves, which cannot meet the needs of users to keep various vegetables and fruits fresh in the refrigerator compartment.

[0083] In addition, the refrigerators mentioned above do not have the function of partitioning different types of food, and cannot meet users' needs for intelligent storage in refrigerators.

[0084] This application provides a refrigerator, which includes a cabinet, a door, shelves, an image recognition device, and a controller. The cabinet interior defines at least one compartment, and an opening is provided on one side of the cabinet. The door is located at the opening, and one side of the door is hinged to one side of the opening. Shelves are located in the compartment, and the shelves and the inner wall of the cabinet together define multiple storage areas for placing food. The preservation conditions of the multiple storage areas are different. The image recognition device is located in the cabinet and is used to identify the types of food stored in the multiple storage areas. The controller is electrically connected to both the illumination component and the image recognition device. The controller is configured to: acquire the types of food in the storage areas and the actual storage areas of the food; match the preset storage areas of the food according to the types of food; determine whether the preset storage areas are the same as the actual storage areas; if not, prompt the user to place the food back in the preset storage areas.

[0085] The refrigerator provided in this application embodiment has multiple storage zones, each with different preservation conditions. Users can store food in suitable zones according to its characteristics, thereby extending its shelf life and reducing nutrient loss. Secondly, through the combination of an image recognition device and a controller, the refrigerator can automatically identify the types of food in the storage zones and intelligently store them according to preset preservation conditions. This not only improves the refrigerator's ease of use but also better meets users' preservation needs for different foods. Furthermore, when a user places food in an unsuitable storage zone, the controller can promptly prompt the user to reposition the food. This prompting function effectively prevents food spoilage due to improper storage, enhancing the user experience. Compared to existing technologies, the refrigerator in this application embodiment can emit light waves of different wavelengths and intensities for adaptive storage of different types of food. The refrigerator can intelligently identify food and manage its storage rationally, allowing users to better plan their food usage and reduce waste caused by spoilage.

[0086] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0087] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0088] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0089] Reference Figure 1 , Figure 2 and Figure 3 In one aspect, embodiments of this application provide a refrigerator 10, including a cabinet 100, a door 200, a shelf 300, a lighting component, an image recognition device 400, and a controller.

[0090] Reference Figure 1Specifically, this application proposes a refrigerator 10, which includes a cabinet 100. The interior of the cabinet 100 is defined to form at least one compartment, which can be configured as a refrigerator compartment or a freezer compartment. An opening 11 is provided on one side of the cabinet 100, and a door 200 is provided at the opening 11. One side of the door 200 is hinged to one side of the opening 11 of the cabinet 100.

[0091] It should be noted that the side of the refrigerator 10 facing the user is the front side of the refrigerator 10, and the side away from the user is the rear side of the refrigerator 10.

[0092] The cabinet 100 can be configured as a refrigerator inner liner, a freezer inner liner, and an outer shell. The refrigerator inner liner encloses the refrigerator compartment, and the freezer inner liner encloses the freezer compartment.

[0093] Shelf 300, lighting components, and image recognition device 400 are all located within the room, as shown in the reference. Figure 5 The controller is electrically connected to both the lighting component and the image recognition device 400.

[0094] The shelf 300 and the inner wall of the box 100 together define multiple storage areas 110 for placing food ingredients, and the shelf 300 is used to support food ingredients.

[0095] As an optional implementation, there can be multiple shelves 300, which can be arranged at intervals. Two adjacent shelves 300 and the inner wall of the box 100 together define a storage area 110. In this way, multiple shelves 300 and the inner wall of the box 100 can jointly define multiple storage areas 110.

[0096] Understandably, the lighting components can emit light waves, such as blue light or ultraviolet light, covering multiple storage areas 110. The intensity of the light waves can be arbitrarily controlled. For example, the controller can control the lighting components to emit light beams of different wavelengths and intensities as needed to suit different ingredients.

[0097] In this system, at least one of the wavelength and intensity of the light waves covering each storage zone 110 is different, resulting in different storage conditions in each zone to accommodate ingredients with varying preservation requirements. This allows users to store ingredients in the appropriate storage zone 110 based on their specific characteristics, thereby extending their shelf life and reducing nutrient loss.

[0098] As an optional implementation, the multiple storage chambers are independent of each other and do not affect each other. These independent storage chambers can store different types of food separately, avoiding cross-contamination and odor mixing, thus improving preservation.

[0099] It is understandable that the multiple independent storage compartments refer to the door 200 being in a closed state. When the door 200 is opened, all storage compartments are connected to the outside, making it convenient for users to view and retrieve the food inside.

[0100] The image recognition device 400 is used to identify the types of food stored. For example, the image recognition device 400 includes a camera, which is used to capture photos of all the food stored in the room. By performing image recognition on the captured photos, the types of food stored can be obtained.

[0101] Furthermore, the aforementioned image recognition device 400 is a color camera. The color camera can capture images inside the preservation room more clearly and transmit the captured images to the controller. The controller determines the type of food based on the color and shape of the food.

[0102] In some embodiments, the image recognition device 400 can be located arbitrarily. For example, the image recognition device 400 can be disposed on the inside of the door 200. Another example is that the image recognition device 400 can be disposed on the inner wall of the housing 100.

[0103] In some embodiments, the controller controls the operation of the refrigerator 1010 and responds to user operations through various software control programs stored in memory. The controller controls the overall operation of the refrigerator 10, for example, responding to received user transmissions or direct operation control commands of the refrigerator 10, and performing operations related to the object selected by the control commands.

[0104] In some embodiments, the controller includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), a RAM (Random Access Memory), a ROM (Read-Only Memory), a first to an nth interface for input / output, a communication bus, etc.

[0105] Reference Figure 6 As an optional implementation, the controller is configured to:

[0106] S10. Obtain the types of ingredients in the storage area and the actual storage area of ​​the ingredients.

[0107] As can be seen from the foregoing, the image recognition device 400 can identify the types of food ingredients so as to carry out adaptive preservation for different types of food ingredients.

[0108] It should be noted that different types of food have different preservation requirements. Correspondingly, the light waves emitted by the lighting components are also relatively different.

[0109] For example, foods with added colorings, such as cheese, jam, and ham, are placed in the room. The colorings are easily decomposed by light, so these foods have a low requirement for light intensity. Another example is apples, melons, and watermelons. These foods have high inherent preservation properties, so their preservation requirements are low, meaning they have a low requirement for light intensity, but they still need some light to maintain freshness for a longer period. Yet another example is blueberries, cherry tomatoes, and green peppers. These foods have certain inherent preservation properties and require a certain intensity of composite light waves. And yet another example is spinach and strawberries. These foods have poor inherent preservation properties and require a high intensity of composite light waves.

[0110] Understandably, while determining the type of food, the controller can also control the image recognition device 400 to obtain the actual storage area of ​​the food, i.e., the actual placement location of the food, in order to determine whether the placement location of the food is appropriate.

[0111] S20. Match the preset storage area of ​​the ingredients according to the type of ingredients.

[0112] It is understandable that different types of ingredients correspond to different storage areas 110 with different preservation requirements. The preservation requirements for the same type of ingredient are fixed. Therefore, once the type of ingredient is obtained, the corresponding storage area 110 is also fixed. For example, when the image recognition device 400 detects that the ingredient is ham, the preservation performance of the preset storage area for that ingredient is low to avoid the decomposition of the ingredient's pigments; for example, when the image recognition device 400 detects that the ingredient is strawberry, the preservation performance of the preset storage area for that ingredient is high to ensure the freshness of the ingredient.

[0113] It should be noted that only one preset storage area is assigned to the same ingredient. However, ingredients with the same preservation properties but belonging to different categories can be assigned to the same preset storage area. For example, cheese and jam are different types of ingredients, but both contain pigments that are easily decomposed by light; their preservation properties are the same, so they can be placed in the same preset storage area. Similarly, blueberries and green peppers are different types of ingredients, but both have some preservation properties, so they can be placed in the same preset storage area.

[0114] S30. Determine whether the preset storage area is the same as the actual storage area.

[0115] Understandably, the controller can determine the type of ingredient and its placement location, i.e., its actual storage area. The controller then retrieves the preset storage area for the ingredient based on its type and compares this preset area with the actual storage area to determine if the placement is appropriate.

[0116] S40. If not, prompt the user to place the ingredients back in the preset storage area.

[0117] Understandably, when the controller determines that the preset storage area is different from the actual storage area, in order to ensure that the preservation requirements of the food and the preservation conditions of the storage area 110 are matched, the controller can prompt the user to take the food out of the actual storage area and then put it back into the preset storage area, so as to ensure that the preservation requirements of the food are the same as the preservation conditions of the actual storage area.

[0118] It should be noted that users can obtain prompts in various ways. In this embodiment, the refrigerator 10 also includes a prompting module, which is used to prompt the user.

[0119] In some embodiments, the indicator module includes an indicator light. The indicator light can illuminate the storage area 110.

[0120] For example, the controller can use an indicator light to alert the user. For instance, when the controller determines that the preset storage area is the same as the actual storage area, the indicator light is off; when the controller determines that the preset storage area is different from the actual storage area, the indicator light is on. Alternatively, for example, when the controller determines that the preset storage area is the same as the actual storage area, the indicator light is on; when the controller determines that the preset storage area 110 is different from the actual storage area, the indicator light is off.

[0121] For example, the controller can use the color of an indicator light to alert the user. For instance, the indicator light emits green light when the controller determines that the preset storage area matches the actual storage area; and it emits red light when the controller determines that the preset storage area differs from the actual storage area.

[0122] In some embodiments, the notification module includes a display screen that can display relevant information.

[0123] For example, the controller can prompt the user by controlling the content displayed on the screen. The displayed content includes, but is not limited to, text, images, etc.

[0124] In some embodiments, the prompting module includes a speaker that can play relevant sounds. For example, the controller can control the sounds played by the speaker to prompt the user.

[0125] It is understood that the prompt module may include one or more of the following: prompt light, display screen, and speaker. This application embodiment does not limit this, and the way users obtain prompt information can be adjusted according to the actual situation.

[0126] The refrigerator 10 provided in this embodiment, through the combination of an image recognition device 400 and a controller, can automatically identify the types of food in the storage area 110 and intelligently store different types of food according to preset preservation conditions. This not only improves the ease of use of the refrigerator 10 but also better meets users' needs for preserving different types of food. Furthermore, when a user places food in an unsuitable storage area 110, the controller can promptly prompt the user to reposition the food. This prompting function effectively prevents food spoilage due to improper storage, enhancing the user experience. Compared with existing technologies, the refrigerator 10 in this embodiment can emit light waves of different wavelengths and intensities to adaptively store different types of food. The refrigerator 10 can intelligently identify food and perform reasonable storage management, allowing users to better plan the use of food and reduce waste caused by food spoilage.

[0127] Reference Figure 2 and Figure 3 As an optional implementation, the storage area 110 located at the top of the box 100 is designated as the first preservation area 111, the storage area 110 located at the bottom of the box 100 is designated as the second preservation area 112, and the storage area 110 located between the first preservation area 111 and the second preservation area 112 is designated as the third preservation area 113.

[0128] It is understandable that when the storage area 110 includes the aforementioned first preservation area 111, second preservation area 112 and third preservation area 113, the preservation conditions of the first preservation area 111, second preservation area 112 and third preservation area 113 are all different.

[0129] Reference Figure 2 and Figure 3 In some embodiments, the light intensity of the light waves covering the first preservation area 111, the third preservation area 113, and the second preservation area 112 gradually increases. That is, the preservation conditions of the first preservation area 111, the third preservation area 113, and the second preservation area 112 are improved sequentially.

[0130] By adjusting the light intensity, the light requirements of different ingredients can be met.

[0131] The first preservation zone, 111, has the lowest light intensity and is suitable for light-sensitive ingredients such as apples, melons, and watermelons. The third preservation zone, 113, has moderate light intensity and is suitable for ingredients with moderate light requirements, such as apples, melons, watermelons, blueberries, cherry tomatoes, and green peppers. The bottom zone has the highest light intensity and is suitable for ingredients that require more light, such as spinach and strawberries.

[0132] By rationally allocating light intensity according to the different light requirements of various ingredients, the freshness time of the ingredients can be extended to the maximum extent and their nutritional components can be preserved.

[0133] Refer to 2 and Figure 3 In some embodiments, the wavelength range of the light waves covering the first preservation area 111, the third preservation area 113, and the second preservation area 112 gradually increases. That is, from the top to the bottom of the refrigerator 10, the wavelength range of the light waves gradually increases to adapt to the lighting needs of food in different areas.

[0134] Understandably, the wavelength of light has a significant impact on plant photosynthesis and preservation. Short wavelengths (such as blue light) help inhibit the growth of certain microorganisms, while long wavelengths (such as red light) help promote plant photosynthesis. By dividing the interior of the refrigerator 10 into multiple preservation zones and setting different wavelengths of light, the preservation needs of different foods can be better met, thereby extending their shelf life and reducing nutrient loss.

[0135] The first preservation zone 111 can use shorter wavelengths of light, which helps inhibit the growth of microorganisms; the third preservation zone 113 uses medium wavelengths of light, which are suitable for most vegetables and fruits; the second preservation zone 112 uses longer wavelengths of light, which helps promote the ripening and preservation of certain fruits.

[0136] By setting up multiple storage zones 110 with gradually increasing light wavelength ranges, suitable lighting conditions for the food in each preservation zone can be provided.

[0137] Reference Figure 2 and Figure 3 As an optional implementation, the third preservation area 113 further includes a low preservation area 115 and a high preservation area 114. The light intensity of the light wave covering the first preservation area 111 is a, the light intensity of the light wave covering the second preservation area 112 is b, the light intensity of the light wave covering the low preservation area 115 is c, and the light intensity of the light wave covering the high preservation area 114 is d. The relationship between a, b, c, and d is as follows:

[0138] a < c < d < b, a ≥ 0 and b, c, d > 0.

[0139] That is, the light intensity of the first preservation zone 111 is the lowest, the light intensity of the second preservation zone 112 is the highest, and the light intensity of the low preservation zone 115 and the high preservation zone 114 of the third preservation zone 113 is between the two.

[0140] By subdividing the third preservation zone 113 into a low preservation zone 115 and a high preservation zone 114, and setting different light intensities, the preservation needs of different ingredients can be met more precisely, thereby extending their preservation time and reducing nutrient loss.

[0141] Light intensity has a significant impact on plant photosynthesis and preservation. Lower light intensities (e.g., a) help inhibit the growth of certain microorganisms, while higher light intensities (e.g., b) help promote plant photosynthesis and maturation.

[0142] By setting the light intensity a < c < d < b, suitable lighting conditions can be provided for the food in different preservation zones. For example, the first preservation zone 111 can use a lower light intensity (a), which helps inhibit the growth of microorganisms and is suitable for foods such as cheese, jam, and ham; the second preservation zone 112 uses a higher light intensity (b), which helps promote the ripening and preservation of certain foods, such as spinach and strawberries; the low preservation zone 115 and the high preservation zone 114 use medium light intensities (c and d) respectively, which are suitable for most vegetables and fruits. The low preservation zone 115 is suitable for foods such as apples, melons, and watermelons, while the high preservation zone 114 is suitable for foods such as blueberries, cherry tomatoes, and green peppers.

[0143] It should be noted that the light intensity of the light waves in each storage area 110 can be adjusted according to the actual situation. This application embodiment does not limit the light intensity of the light waves in each storage area 110.

[0144] Through the above settings, multiple preservation zones with tiered light intensity distribution can be created based on the different characteristics of the ingredients, thus meeting the preservation needs of various foods. The image recognition device 400 can identify the placement of the ingredients; if the user places the ingredients in an unsuitable area, the refrigerator 10 will promptly prompt the user to reposition them, thereby ensuring optimal preservation.

[0145] As an optional implementation, the third preservation zone 113 also includes a low preservation zone 115 and a high preservation zone 114.

[0146] The light waves emitted by the light-emitting component do not cover the first preservation area 111, that is, the first preservation area 111 is a light-free area, which is suitable for some foods that do not require light, such as cheese, jam, ham, etc. By illuminating the first preservation area 111 without covering it, the unnecessary light can be avoided from affecting these foods.

[0147] It should be noted that light waves of different wavelengths have different functions. For example, blue light (420nm-480nm) helps inhibit the growth of microorganisms, while red light (620nm-670nm) helps promote photosynthesis and ripening in plants. Violet light (200nm-420nm) helps kill bacteria. White light is used to provide illumination. Near-infrared light (800nm-1100nm) helps promote the ripening and preservation of certain fruits.

[0148] The light waves covering the low-freshness zone 115 include blue light with a wavelength range of 420nm-480nm and red light with a wavelength range of 620nm-670nm. That is, the light waves in the low-freshness zone 115 are a composite of blue and red light, suitable for foods such as apples, melons, and watermelons. By providing blue and red light to the low-freshness zone 115, the growth of microorganisms can be effectively inhibited, while promoting photosynthesis in the food, thus extending its shelf life.

[0149] The light waves covering the high-preservation zone 114 include blue light with wavelengths ranging from 420nm to 480nm, red light with wavelengths ranging from 620nm to 670nm, and white light with wavelengths ranging from 380nm to 760nm. In other words, the light waves in the high-preservation zone 114 are a composite of blue, red, and white light, suitable for ingredients such as blueberries, cherry tomatoes, and green peppers. By providing blue, red, and white light in the high-preservation zone 114, an optimal preservation environment can be provided for ingredients that require more comprehensive lighting conditions, further extending their shelf life and reducing nutrient loss.

[0150] The light waves covering the second preservation zone 112 include violet light (200nm-420nm), blue light (420nm-480nm), red light (620nm-670nm), white light (380nm-760nm), and near-infrared light (800nm-1100nm). In other words, the light waves in the second preservation zone 112 are a composite of violet, blue, red, white, and near-infrared light, suitable for ingredients such as spinach and strawberries. By providing comprehensive illumination from ultraviolet to near-infrared in the second preservation zone 112, an optimal preservation environment can be provided for ingredients requiring the most comprehensive light conditions, significantly extending their shelf life and reducing nutrient loss.

[0151] Through the above settings, multiple preservation zones with different wavelength ranges can be formed according to the different characteristics of the ingredients, thus meeting the preservation needs of different ingredients. The image recognition device 400 can identify the placement of the ingredients; if the user places the ingredients in an unsuitable area, the refrigerator 10 will promptly prompt the user to reposition them, thereby ensuring optimal preservation.

[0152] Reference Figure 2 and Figure 3In some embodiments, the first preservation area 111, the low preservation area 115, the high preservation area 114, and the second preservation area 112 can simultaneously satisfy the aforementioned embodiments of light intensity and wavelength range. That is, in the embodiments of this application, the first preservation area 111 has no light wave coverage, the lowest light intensity, and the smallest light wave range; the low preservation area 115 has a relatively low light intensity and a small light wave range; the high preservation area 114 has a relatively high light intensity and a large light wave range; and the second preservation area 112 has the highest light intensity and the largest light wave range.

[0153] As an optional implementation, the lighting assembly includes multiple lighting elements, which are located one-to-one in the second preservation zone 112, the high preservation zone 114, and the low preservation zone 115.

[0154] Understandably, different storage zones 110 have different lighting requirements. By distributing lighting elements one-to-one within each storage zone 110, the lighting conditions in each zone can be precisely controlled to ensure that the food in each storage zone 110 receives optimal lighting conditions, thereby extending its shelf life and reducing nutrient loss. For example, the lighting elements in the low-preservation zone 115 can provide blue and red light, the lighting elements in the high-preservation zone 114 can provide blue, red, and white light, while the lighting elements in the second preservation zone 112 can provide comprehensive lighting from ultraviolet to near-infrared.

[0155] By equipping each storage zone 110 with a dedicated lighting unit, the light intensity and wavelength can be flexibly adjusted according to the different needs of the ingredients to meet the preservation requirements of different types of ingredients. For example, some ingredients that require lower light intensity can be placed in the low preservation zone 115, while ingredients that require higher light intensity can be placed in the high preservation zone 114. The comprehensive lighting in the second preservation zone 112 is suitable for ingredients that require the most comprehensive lighting conditions.

[0156] Through an image recognition system and controller, the lighting conditions of each light source can be automatically adjusted after detecting the type of food to suit the needs of food in different storage zones 110. This improves the ease of use of the refrigerator 10 and effectively prevents food spoilage caused by improper lighting conditions. For example, when a user places a food that requires a specific wavelength of light in a storage zone 110, the light source can automatically adjust the lighting conditions to ensure optimal preservation.

[0157] By equipping each storage area 110 with a dedicated light source, the light intensity and duration can be adjusted according to actual needs, avoiding unnecessary energy waste. This can significantly reduce the energy consumption of the refrigerator 10, extend the lifespan of the light source, and reduce the impact on the environment.

[0158] Reference Figure 2 and Figure 3As an optional implementation, the lighting components are located in the second preservation area 112. By centrally arranging the lighting components in the second preservation area 112, the number of lighting components can be reduced, simplifying the design and lowering costs. The centralized light source design can improve the utilization rate of the lighting components and ensure that light waves can cover multiple preservation areas, thereby achieving efficient lighting management.

[0159] The second preservation zone 112, the high preservation zone 114, and the low preservation zone 115 are all covered by light waves emitted from the lighting component. By ensuring that the light waves emitted by the lighting component cover the second preservation zone 112, the high preservation zone 114, and the low preservation zone 115, it can be ensured that all preservation zones receive adequate lighting. This uniform light source coverage design simplifies the structure of the lighting system, ensures that each preservation zone receives the required lighting conditions, thereby extending the shelf life of food and reducing nutrient loss.

[0160] A light filter layer is provided between the second preservation zone 112 and the high preservation zone 114, between the high preservation zone 114 and the low preservation zone 115, and between the low preservation zone 115 and the first preservation zone 111. The light filter layer is configured to block some wavelengths of light and reduce the light intensity. The light filter layer can block some wavelengths of light and reduce the light intensity, thereby providing suitable lighting conditions for different preservation zones.

[0161] By placing filter layers between the second preservation zone 112 and the high preservation zone 114, between the high preservation zone 114 and the low preservation zone 115, and between the low preservation zone 115 and the first preservation zone 111, fine-tuning of light waves can be achieved. For example, the filter layers can block certain unwanted wavelengths while reducing light intensity to suit the needs of different zones. This design ensures that each preservation zone receives optimal lighting conditions, thereby extending the shelf life of food.

[0162] In some embodiments, in order to ensure the smooth propagation of light waves, the shelf 300 can be made of transparent material, and a filter layer is covered on the surface of the shelf 300.

[0163] It is understood that the material used to prepare the shelf 300 can be arbitrary. This application does not limit the specific material of the shelf 300. The following description uses glass shelf 300 as the shelf.

[0164] It is understandable that different filter layers can have different filtering effects.

[0165] In some embodiments, the illumination component may emit a composite light wave including white light, red light, blue light, near-infrared light, and violet light.

[0166] For example, the second preservation area 112 is covered by white light, red light, blue light, near-infrared light and violet light emitted by the light irradiation component.

[0167] For example, the filter layer between the second preservation zone 112 and the high preservation zone 114 is used to block near-infrared light and violet light, and has a light transmittance of 80%-100%, so that the high preservation zone 114 is covered by red light, white light and blue light.

[0168] For example, the filter layer between the high preservation zone 114 and the low preservation zone 115 is used to block white light and has a light transmittance of 60%-80%, so that the low preservation period is covered by red and blue light with reduced light intensity.

[0169] For example, the filter layer between the low preservation zone 115 and the first preservation zone 111 has a light transmittance of 0-20%, so that the first preservation zone 111 is covered by the weakest red and blue light, or even without light wave coverage.

[0170] By using a light filter layer, the lighting conditions of each preservation zone can be flexibly adjusted without the need for additional lighting components, significantly improving the adaptability and ease of use of the refrigerator 10. For example, when a certain preservation zone requires a specific wavelength of light, the light filter layer can block other wavelengths of light, thereby providing optimal lighting conditions. This design not only enhances the functionality of the refrigerator 10 but also effectively prevents food spoilage caused by improper lighting conditions.

[0171] Reference Figure 7 As an optional implementation, the controller is also configured to:

[0172] S21. Determine whether the preset storage area is the first preservation area; Step S21 is executed after step S20, that is, after matching the preset storage area of ​​the ingredients according to the type of ingredients. Based on step S21, continue to determine:

[0173] If not, proceed to step S22, namely:

[0174] S22. Determine whether the actual storage area is the first preservation area;

[0175] If so, proceed to step S23A, that is:

[0176] S23A, prompting the user to remove the food from the first preservation area and place it back in the preset storage area.

[0177] As can be seen from the above, the first preservation zone 111 has the lowest preservation conditions. When foods with high preservation requirements, such as apples, melons, watermelons, blueberries, cherry tomatoes, green peppers, spinach, and strawberries, are placed in the first preservation zone 111, they are prone to spoilage due to insufficient preservation conditions.

[0178] The controller determines whether the preset storage area is the first preservation area 111. If food that does not belong to the first preservation area 111 is placed in the first preservation area 111, the user is prompted to take the food out of the first preservation area 111 and put it back. This can promptly remind the user to correct the wrong placement behavior and avoid food spoilage caused by misplacement.

[0179] Based on this, the controller can control the operation of the prompt module, such as controlling the prompt light to emit a red light to warn the user of incorrect placement, controlling the speaker to emit a warning sound, and controlling the display screen to display warning content, to prompt the user to adjust the position of the ingredients.

[0180] Based on the foregoing, refer to Figure 8 As an optional implementation, after step S21, the following determination is made:

[0181] If so, proceed to step S22, that is:

[0182] S22. Determine whether the actual storage area is the first preservation area;

[0183] If not, proceed to step S23B, namely:

[0184] S23B, prompting the user to remove the food from the actual storage area and place it back in the first preservation area.

[0185] As can be seen from the foregoing, the first preservation zone 111 has the lowest preservation conditions. When ingredients such as cheese, jam, and ham that are suitable for storing in the first preservation zone 111 are placed in other storage zones 110 with higher light intensity, the pigments of these ingredients are easily decomposed by light, which in turn causes the ingredients to spoil.

[0186] The controller determines whether the preset storage area is the first preservation area 111. When it is determined that the food belonging to the first preservation area 111 is placed in its storage area 110, the user is prompted to take out the food and put it back in the first preservation area 111. This can promptly remind the user to correct the incorrect placement behavior and avoid food spoilage due to misplacement.

[0187] Based on this, the controller can control the operation of the prompt module, such as controlling the prompt light to emit a red light to warn the user of incorrect placement, controlling the speaker to emit a warning sound, and controlling the display screen to display warning content, to prompt the user to adjust the position of the ingredients.

[0188] Reference Figure 9 As an optional implementation, the controller is also configured to:

[0189] S24. Determine whether the preset storage area is the second preservation area; Step S24 is executed after step S20, that is, after matching the preset storage area of ​​the ingredients according to the type of ingredients. Based on step S24, continue to determine:

[0190] If so, proceed to step S25, that is:

[0191] S25. Determine whether the actual storage area is the third preservation area;

[0192] If so, proceed to step S26, that is:

[0193] S26. It is recommended that users remove the ingredients from the actual storage area and place them back in the second preservation area.

[0194] As described above, the second preservation zone 112 offers the highest preservation conditions, while the third preservation zone 113 offers lower preservation conditions. Therefore, the second preservation zone 112 can also be used to store ingredients suitable for the third preservation zone 113, and vice versa. For example, when ingredients suitable for storing in the second preservation zone 112, such as apples, melons, watermelons, blueberries, cherry tomatoes, and green peppers, are placed in the second preservation zone 112, short-term preservation of these ingredients can be achieved. Similarly, when ingredients suitable for storing in the third preservation zone 113, such as spinach and strawberries, are placed in the third preservation zone 113, short-term preservation of these ingredients can also be achieved.

[0195] However, the mismatch between the preservation requirements of food ingredients and the preservation conditions of actual storage areas can affect the long-term storage of food ingredients.

[0196] Therefore, when the controller determines that food belonging to the second preservation area 112 has been placed in the third preservation area 113, it prompts the user to remove the food and put it back in the second preservation area 112. This can promptly remind the user to correct the incorrect placement behavior and avoid food spoilage caused by misplacement.

[0197] Based on this, the controller can control the operation of the prompt module, such as controlling the prompt light to emit an orange light to warn the user of incorrect placement, controlling the speaker to emit a warning sound, and controlling the display screen to display warning content, to prompt the user to adjust the position of the ingredients.

[0198] In another example, when the controller determines that food belonging to the third preservation area 113 is placed in the second preservation area 112, it prompts the user to remove the food and place it back in the third preservation area 113. This can immediately prompt the user to correct the incorrect placement behavior and avoid food spoilage caused by misplacement.

[0199] Based on this, the controller can control the operation of the prompt module, such as controlling the prompt light to emit blue light to warn the user of incorrect placement, controlling the speaker to emit a warning sound, and controlling the display screen to display warning content, to prompt the user to adjust the position of the ingredients.

[0200] Understandably, since the preservation conditions of the second preservation zone 112 are higher than those of the third preservation zone 113, when food suitable for the third preservation zone 113 is placed in the second preservation zone 112, the second preservation zone 112 can better maintain the freshness of the food, but this will result in a waste of the preservation capacity of the refrigerator 10, without affecting the storage of the food.

[0201] Reference Figure 3 As an optional implementation, a humidification module 500 is also provided in the second preservation zone 112, which is used to adjust the humidity of the second preservation zone 112.

[0202] Humidity is one of the most important factors affecting the preservation of food. Precise humidity control can significantly improve the preservation effect. The humidification module 500 can increase the humidity in the second preservation zone 112, preventing food from losing moisture and drying out, thus maintaining its freshness and taste. For example, fruits can retain moisture in a high-humidity environment, preventing them from drying out and losing flavor.

[0203] By installing a humidification module 500 in the second preservation zone 112, the humidity in this zone can be precisely controlled, ensuring that food is stored under optimal humidity conditions, thereby extending its shelf life and reducing nutrient loss. For example, leafy vegetables can stay fresh for longer in a high-humidity environment, while fruits can avoid dehydration and drying out under appropriate humidity.

[0204] It should be noted that the humidification module 500 can automatically adjust the humidity according to the needs of the food in the second preservation zone 112 to ensure the best preservation effect. For example, some foods that require a high humidity environment can stay fresh for a longer time in the second preservation zone 112, while foods that do not require high humidity can avoid spoilage caused by excessive moisture.

[0205] Through the intelligent control system, the working status of the humidification module 500 can be automatically adjusted according to the different needs of the ingredients to provide a suitable humidity environment.

[0206] Reference Figure 2 and Figure 3As an optional implementation, to ensure humidity maintenance, the shelf 300 that surrounds the second preservation area 112 can be a drawer 600 with a certain sealing capability. The drawer 600 has an opening 11, and adjacent shelves 300 are used to cover the opening 11. The drawer 600 can slide to open or close the opening 11. The drawer 600, the adjacent shelves 300, and the inner wall of the box body 100 together form the second preservation area 112.

[0207] In some embodiments, a humidity sensor is also provided inside the drawer 600 to monitor the humidity of the second preservation zone 112. The humidity sensor is electrically connected to the controller, which can acquire the humidity information sensed by the humidity sensor to adjust the power of the humidification module 500 according to the humidity information, thereby adjusting the humidity in the second preservation zone 112.

[0208] As an optional implementation, at least one of the housing 100 and the door 200 is provided with a sensor switch (not shown in the figure), which is electrically connected to the lighting component; the sensor switch is used to obtain the distance between the door 200 and the housing 100.

[0209] The sensor switch can automatically control the on / off state of the lighting component based on the distance between the door 200 and the refrigerator body 100. For example, when the refrigerator door 10 is opened, the sensor switch detects an increase in the distance between the door 200 and the refrigerator body 100 and automatically turns off the lighting component to save energy; when the refrigerator door 10 is closed, the sensor switch detects a decrease in the distance and automatically turns on the lighting component to provide suitable lighting conditions. This automatic control method not only improves the ease of use of the refrigerator 10 but also effectively saves energy.

[0210] It is understandable that frequent opening and closing operations may shorten the lifespan of the lighting components. Intelligent control via a sensor switch can reduce unnecessary opening and closing operations. The sensor switch can intelligently control the on / off state of the lighting components based on the distance between the door 200 and the cabinet 100, reducing unnecessary opening and closing operations and thus extending the lifespan of the lighting components. For example, when the refrigerator door 10 is closed for an extended period, the lighting components can remain on; when the refrigerator door 10 is frequently opened, the lighting components can automatically turn off within a short time, avoiding wear and tear caused by frequent opening and closing.

[0211] It should be noted that users may need to operate the refrigerator 10 with the door open. The intelligent control via the sensor switch can automatically adjust the lighting conditions when the refrigerator door is opened, improving the user experience.

[0212] Reference Figure 10 As an optional implementation, the controller is also configured to:

[0213] S50. Determine whether the refrigerator is sealed based on the distance between the door and the cabinet.

[0214] Understandably, the airtightness of refrigerator 10 has a significant impact on its preservation effect and energy consumption. By obtaining the distance between the door 200 and the cabinet 100 through a sensor switch, the controller can determine whether the refrigerator 10 door is fully closed, thereby determining whether refrigerator 10 is airtight.

[0215] By using a controller to determine whether the refrigerator 10 is sealed, it can promptly detect situations where the refrigerator door is not fully closed, thus preventing temperature fluctuations and increased energy consumption caused by poor sealing. For example, when the controller detects that the distance between the door 200 and the cabinet 100 is greater than a preset value, it can determine that the refrigerator 10 is not sealed and take appropriate measures.

[0216] Based on step S50, continue the judgment:

[0217] If not, proceed to step S60, namely:

[0218] S60, controls the lighting component to emit white light with a wavelength range of 380nm-760nm. The white light is used to illuminate the storage compartment of the refrigerator 10.

[0219] Understandably, the controller can activate the lighting component to emit white light when it detects that the refrigerator 10 is not sealed. This serves two purposes: firstly, it promptly alerts the user to check and close the refrigerator 10 door, ensuring its airtightness. For instance, if a user sees white light emanating from inside the refrigerator 10, they will realize that the door is not fully closed and can take timely measures to prevent food spoilage and increased energy consumption due to poor sealing.

[0220] On the other hand, when the refrigerator 10 is not sealed, it may be that the user is using the refrigerator 10. For this reason, the controller controls the lighting component to emit white light, which can illuminate the inside of the refrigerator 10 for the user's convenience.

[0221] Reference Figure 1 , Figure 2 and Figure 3 Secondly, embodiments of this application also provide a refrigerator 10, including a cabinet 100, a door 200, a shelf 300, a lighting component, an image recognition device 400, and a controller. The cabinet 100, door 200, shelf 300, lighting component, image recognition device 400, and controller have all been described above and will not be repeated here.

[0222] As an optional implementation, the controller is configured to:

[0223] S10. Obtain the types of ingredients in the storage area and the actual storage area of ​​the ingredients.

[0224] As can be seen from the foregoing, the image recognition device 400 can identify the types of food ingredients so as to carry out adaptive preservation for different types of food ingredients.

[0225] It should be noted that different types of food have different preservation requirements. Correspondingly, the light waves emitted by the lighting components are also relatively different.

[0226] For example, foods with added colorings, such as cheese, jam, and ham, are placed in the room. The colorings are easily decomposed by light, so these foods have a low requirement for light intensity. Another example is apples, melons, and watermelons. These foods have high inherent preservation properties, so their preservation requirements are low, meaning they have a low requirement for light intensity, but they still need some light to maintain freshness for a longer period. Yet another example is blueberries, cherry tomatoes, and green peppers. These foods have certain inherent preservation properties and require a certain intensity of composite light waves. And yet another example is spinach and strawberries. These foods have poor inherent preservation properties and require a high intensity of composite light waves.

[0227] Understandably, while determining the type of food, the controller can also control the image recognition device 400 to obtain the actual storage area of ​​the food, i.e., the actual placement location of the food, in order to determine whether the placement location of the food is appropriate.

[0228] S20. Match the preset storage area of ​​the ingredients according to the type of ingredients.

[0229] It is understandable that different types of ingredients correspond to different storage areas 110 with different preservation requirements. The preservation requirements for the same type of ingredient are fixed. Therefore, once the type of ingredient is obtained, the corresponding storage area 110 is also fixed. For example, when the image recognition device 400 detects that the ingredient is ham, the preservation performance of the preset storage area for that ingredient is low to avoid the decomposition of the ingredient's pigments; for example, when the image recognition device 400 detects that the ingredient is strawberry, the preservation performance of the preset storage area for that ingredient is high to ensure the freshness of the ingredient.

[0230] It should be noted that only one preset storage area is assigned to the same ingredient. However, ingredients with the same preservation properties but belonging to different categories can be assigned to the same preset storage area. For example, cheese and jam are different types of ingredients, but both contain pigments that are easily decomposed by light; their preservation properties are the same, so they can be placed in the same preset storage area. Similarly, blueberries and green peppers are different types of ingredients, but both have some preservation properties, so they can be placed in the same preset storage area.

[0231] S30. Determine whether the preset storage area is the same as the actual storage area.

[0232] Understandably, the controller can determine the type of ingredient and its placement location, i.e., its actual storage area. The controller then retrieves the preset storage area for the ingredient based on its type and compares this preset area with the actual storage area to determine if the placement is appropriate.

[0233] S40. If not, prompt the user to place the ingredients back in the preset storage area.

[0234] Understandably, when the controller determines that the preset storage area is different from the actual storage area, in order to ensure that the preservation requirements of the food and the preservation conditions of the storage area 110 are matched, the controller can prompt the user to take the food out of the actual storage area and then put it back into the preset storage area, so as to ensure that the preservation requirements of the food are the same as the preservation conditions of the actual storage area.

[0235] It should be noted that users can obtain prompts in various ways. In this embodiment, the refrigerator 10 also includes a prompting module, which is used to prompt the user. The prompting module has also been described above and will not be repeated here.

[0236] The refrigerator 10 provided in this embodiment, through the combination of an image recognition device 400 and a controller, can automatically identify the types of food in the storage area 110 and intelligently store different types of food according to preset preservation conditions. This not only improves the ease of use of the refrigerator 10 but also better meets users' needs for preserving different types of food. Furthermore, when a user places food in an unsuitable storage area 110, the controller can promptly prompt the user to reposition the food.
