Refrigeration device and control method thereof
[0001] The present disclosure relates to a refrigeration device and a method for controlling the same.
[0002] For breast milk consumed by newborns and infants, the importance of refrigerators in safely maintaining freshness and nutrients for health management is increasing. Furthermore, while it is important to use breast milk in the order it was expressed, there are difficulties in labeling storage dates and managing the milk stored in the refrigerator in the correct sequence.
[0003] In addition, snacks that children often eat are mainly starchy foods such as bread, rice cakes, and cookies. If stored at the standard refrigerator setting of 4°C, starch retrogradation may occur, which can reduce the taste and texture of the food.
[0004] Therefore, there is a growing need for technology to control temperature to prevent damage to the quality of breast milk and starchy foods, and to efficiently manage the entry and exit of food stored in refrigerators.
[0005] A refrigeration device according to one or more embodiments of the present disclosure comprises a camera, a storage chamber, a cold air supply device, a memory storing at least one instruction, and a processor. When the at least one instruction is executed collectively or individually by the processor, the refrigeration device captures a food placed in the storage chamber through the camera to acquire an image, inputs the acquired image into an artificial intelligence model to acquire food information corresponding to the food placed in the storage chamber, identifies an operating mode of the refrigeration device based on the food information, and controls the temperature inside the storage chamber through the cold air supply device based on the identified operating mode.
[0006] The above food information may include information on the type of the food, date information on the food, location information of the food within the storage room, and information on whether the food has been opened.
[0007] When the above at least one instruction is executed collectively or individually by the processor, the refrigeration device identifies a snack storage mode when the input food corresponds to a starchy food, controls the internal temperature of the storage chamber to a first refrigeration temperature for a preset time through the cold air supply device, and controls the internal temperature of the storage chamber to a second refrigeration temperature through the cold air supply device after the preset time.
[0008] The device further includes a vacuum module, and when the at least one instruction is executed collectively or individually by the processor, the refrigeration device can control the internal temperature of the storage room through the cold supply device so that the first refrigeration temperature and the second refrigeration temperature are repeated when the food is identified as opened, and can reduce the oxygen concentration inside the storage room through the vacuum module.
[0009] When the above at least one instruction is executed collectively or individually by the processor, the refrigeration device may provide a notification based on the food information if it satisfies a preset condition corresponding to the entry / exit of the food or the consumption of the food.
[0010] When the above at least one instruction is executed collectively or individually by the processor, the refrigeration device may identify a breast milk storage mode when the food corresponds to breast milk, and upon receiving user input selecting a storage method, control the internal temperature of the storage chamber to a temperature corresponding to the selected storage method through the cold supply device.
[0011] When the above at least one instruction is executed collectively or individually by the processor, the refrigeration device may, upon receiving user input corresponding to short-term storage, control the internal temperature of the storage room to a first refrigeration temperature for a preset time and then to a preset temperature through the cold air supply device, and upon receiving user input corresponding to long-term storage, control the internal temperature of the storage room to a first freezing temperature for a preset time and then to a second freezing temperature through the cold air supply device.
[0012] When the above at least one instruction is executed collectively or individually by the processor, the refrigeration device may provide a notification based on the food information when a preset period has elapsed since the time the food was introduced.

[0091] The processor (140) can be controlled to process input data according to predefined operation rules or artificial intelligence models stored in memory (130). Alternatively, if the processor (140) is an artificial intelligence-dedicated processor, the artificial intelligence-dedicated processor may be designed with a hardware structure specialized for processing a specific artificial intelligence model. The predefined operation rules or artificial intelligence models are characterized by being created through learning.
[0092] The refrigeration device (100) can identify the operating mode of the refrigeration device (100) based on food information (S330). Specifically, the refrigeration device (100) can identify an operating mode corresponding to the type of food introduced. At this time, the operating mode of the refrigeration device (100) may be a mode for controlling the temperature inside the storage room (120) according to the food introduced. The operating mode of the refrigeration device (100) may include a snack storage mode and a breast milk storage mode. The snack storage mode may be a mode for controlling the temperature inside the storage room (120) to store starchy food when the food introduced corresponds to starchy food. At this time, the snack storage mode may be referred to as a first operating mode, a snack mode, or a kids mode. The breast milk storage mode may be a mode for controlling the temperature inside the storage room (120) to store breast milk (20) when the food introduced corresponds to breast milk. At this time, the breast milk storage mode may be referred to as a second operating mode, a breast milk mode, or a baby mode.
[0093] The refrigeration device (100) can identify a snack storage mode if the input food corresponds to a starchy food (S340). A starchy food may be a food containing starch as a main ingredient. For example, a starchy food may include rice cakes, cookies, bread, etc. The starchy food is at a set temperature of 0 to 5 of the refrigeration device (100). If stored in such conditions, starch retrogradation occurs, which may reduce the taste and texture of the food. In addition, starchy foods 10 If stored at above, microbial growth may be promoted, which may reduce food safety.
[0094] The refrigeration device (100) can control the internal temperature of the storage room (120) to a temperature corresponding to the snack storage mode (S350). Specifically, the refrigeration device (100) can control the internal temperature of the storage room (120) to a first refrigeration temperature for a preset time. The first refrigeration temperature may be a temperature corresponding to a sub-zero temperature for reducing the temperature of the food in a short period of time. By controlling the internal temperature of the storage room (120) to the first refrigeration temperature for a preset time, the refrigeration device (100) can lower the temperature of the food in a short period of time and minimize the deterioration of quality.
[0095] The refrigeration device (100) can control the internal temperature of the storage chamber (120) to a second refrigeration temperature after a preset time. The second refrigeration temperature may be a temperature that minimizes starch aging while inhibiting the growth of microorganisms. The second refrigeration temperature may be a temperature higher than the preset temperature. At this time, the preset temperature may be the internal temperature of the storage chamber (120) when refrigerating general food that is not a starchy food. For example, the preset temperature is 0 to 5 It may be a temperature corresponding to a ℃ temperature. According to one embodiment, the second refrigeration temperature is 5 to 10 It may be a temperature corresponding to. When the food introduced into the refrigeration device (100) corresponds to a starchy food, the internal temperature of the storage room (120) is controlled to a second refrigeration temperature, thereby minimizing starch aging and ensuring the same storage stability as in the case of refrigeration.
[0096] That is, the first refrigeration temperature may be lower than the second refrigeration temperature. The refrigeration device (100) can lower the temperature of the food in a short period of time by controlling the internal temperature of the storage room (120) to the first refrigeration temperature for a preset time before controlling the internal temperature of the storage room (120) to the second refrigeration temperature.
[0097] FIG. 4 is a graph showing the control temperature inside the storage room (120) when a starchy food is introduced into a refrigeration device (100) according to at least one embodiment of the present disclosure.
[0098] Referring to FIG. 4, when a starchy food at room temperature is introduced into the storage room (120), the refrigeration device (100) can control the internal temperature of the storage room (120) to a first refrigeration temperature (410) for a preset time. The section (430) during which the refrigeration device (100) controls the internal temperature of the storage room (120) to the first refrigeration temperature (410) may be referred to as a "rapid cooling section" or a "cold shock section." In the rapid cooling section (430), the temperature of the food can be reduced in a short period of time to minimize the deterioration of quality. After the rapid cooling section (430), the refrigeration device (100) can control the internal temperature of the storage room (120) to a second refrigeration temperature (420). The section (440) during which the refrigeration device (100) controls the internal temperature of the storage room (120) to the second refrigeration temperature (420) may be referred to as a "storage section." The storage section (440) can minimize starch aging of starchy food by maintaining the second refrigeration temperature (420).
[0099] Meanwhile, when the refrigeration device (100) identifies that the food has been opened, it can control the internal temperature of the storage room (120) to alternate between the first refrigeration temperature and the second refrigeration temperature.
[0100] The refrigeration device (100) can identify whether the food inserted is opened. According to one embodiment, the refrigeration device (100) can identify whether the food is opened by inputting an image of the food inserted into an artificial intelligence model. In another embodiment, the refrigeration device (100) can identify whether the food is opened based on a symbol or pattern marked by a user on the packaging or outer surface of the container of the food inserted. In this case, the refrigeration device (100) can identify that the food inserted is opened if the food inserted is stored in a container without a lid or if the packaging is opened.
[0101] When the refrigeration device (100) identifies that the food has been opened, it can control the internal temperature of the storage room (120) to alternate between a first refrigeration temperature and a second refrigeration temperature. Specifically, when the refrigeration device (100) identifies that the food inserted has been opened, it can control the internal temperature of the storage room (120) to alternate between a period during which the internal temperature is controlled to a second refrigeration temperature for a preset time and a period during which the internal temperature of the storage room (120) is controlled to a first refrigeration temperature for a preset time. Since the spoilage of food may be accelerated when the food is opened, the refrigeration device (100) can improve shelf life by controlling the internal temperature of the storage room (120) to a second refrigeration temperature and then reducing it to a first refrigeration temperature at preset intervals.
[0102] FIG. 5 is a graph showing the control temperature inside the storage room (120) when an opened starchy food product according to at least one embodiment of the present disclosure is introduced.
[0103] Referring to FIG. 5, when an opened food item at room temperature is introduced, the refrigeration device (100) can control the internal temperature of the storage room (120) to a first refrigeration temperature (510) for a preset time. Afterward, the refrigeration device (100) can control the internal temperature of the storage room (120) to a second refrigeration temperature (520). At this time, the refrigeration device (100) can control the internal temperature of the storage room (120) to the first refrigeration temperature (510) at preset time intervals, rather than maintaining it at the second refrigeration temperature (520) continuously. That is, the refrigeration device (100) can repeat a rapid cooling section (530) in which the internal temperature of the storage room (120) is controlled to the first refrigeration temperature (510) for a preset time, and a storage section (540) in which the internal temperature is controlled to the second refrigeration temperature (520) for a preset time. For example, the refrigeration device (100) can repeat the interval of controlling the internal temperature of the storage room (120) to a first refrigeration temperature (510) for 1 hour and the interval of controlling the internal temperature of the storage room (120) to a second refrigeration temperature (520) for 23 hours.
[0104] Additionally, the refrigeration device (100) can reduce the oxygen concentration inside the storage room (120). Specifically, the refrigeration device (100) can reduce the oxygen concentration inside the storage room (120) by removing some of the air inside the sealed storage room (120) or by removing only some of the oxygen inside the storage room (120). In one embodiment, the refrigeration device (100) can discharge air to the outside by utilizing the pressure difference between the inside and outside of the sealed storage room (120). In another embodiment, the refrigeration device (100) can reduce the oxygen concentration by removing oxygen inside the storage room (120) using a chemical reaction with an oxygen absorbent or by physically adsorbing it to an oxygen adsorbent. In yet another embodiment, the refrigeration device (100) can reduce the oxygen concentration by injecting carbon dioxide gas into the sealed storage room (120).
[0105] The refrigeration device (100) can identify the breast milk storage mode if the food introduced corresponds to breast milk (S360). The refrigeration device (100) can identify that the food introduced corresponds to breast milk through an image taken of a baby bottle or breast milk storage pack. The refrigeration device (100) can obtain information about the date and time the breast milk was obtained by identifying the date information written by the user on the baby bottle or breast milk storage pack.
[0106] The refrigeration device (100) may receive user input selecting a storage method (S370). At this time, the storage method may include short-term storage or long-term storage. Short-term storage may refer to storing breast milk within a few days. Long-term storage may refer to storing breast milk for several months. When the refrigeration device (100) identifies the breast milk storage mode, it may display a UI on the display that allows selection of short-term storage or long-term storage and receive input from the user regarding the UI corresponding to short-term storage or long-term storage. Alternatively, the refrigeration device (100) may receive user input selecting a storage method through an external device (200) connected to the refrigeration device (100).
[0107] When the refrigeration device (100) receives user input selecting a storage method, it may provide information about a storage room corresponding to the selected storage method. When the refrigeration device (100) receives user input corresponding to short-term storage, it may provide information about a first storage room corresponding to short-term storage. At this time, the first storage room may refer to a storage room in which food can be stored by controlling the internal temperature to a set temperature (e.g., 0 to 5°C). Breast milk can be stored while maintaining its quality for up to several days at the set temperature.
[0108] Additionally, when the refrigeration device (100) receives user input corresponding to long-term storage, it may provide information about a second storage room corresponding to long-term storage. At this time, the second storage room may refer to a storage room in which food can be frozen by controlling the internal temperature to a freezing temperature (e.g., minus 15 to minus 18°C). Breast milk can be stored while maintaining its quality for several months at freezing temperatures.
[0109] Meanwhile, the refrigeration device (100) can provide a guide notification to the user to store breast milk in the storage room, along with information about the storage room corresponding to the selected storage method.
[0110] When the refrigeration device (100) receives user input selecting a storage method, it can control the internal temperature of the storage room (120) to a temperature corresponding to the selected storage method (S380). Specifically, when the refrigeration device (100) receives user input corresponding to short-term storage, it can control the internal temperature of the storage room (120) to a first refrigeration temperature for a preset time and then control it to a set temperature. At this time, the set temperature may be the internal temperature of the storage room (120) when refrigerating general food that is not starchy food. For example, the set temperature may be a temperature corresponding to 0 to 5°C. By controlling the internal temperature of the storage room (120) to the first refrigeration temperature for a preset time, the refrigeration device (100) can lower the temperature of breast milk in a short period and minimize the deterioration of quality. After the preset time, the refrigeration device (100) can control the internal temperature of the storage room (120) to a set temperature.
[0111] On the other hand, when the refrigeration device (100) receives input from a user corresponding to long-term storage, it can control the internal temperature of the storage room (120) to a first freezing temperature for a preset time and then to a second freezing temperature. At this time, the first freezing temperature may be a temperature for freezing the food introduced in a short period. For example, the first freezing temperature may be a temperature corresponding to minus 30°C. The section in which the internal temperature of the refrigeration device (100) is controlled to the first freezing temperature for a preset time may be referred to as the rapid freezing section. By controlling the internal temperature of the storage room (120) to the first freezing temperature for a preset time, the refrigeration device (100) can freeze the temperature of the breast milk in a short period, thereby forming small ice crystals and minimizing the deterioration of quality. After the preset time, the refrigeration device (100) may control the internal temperature of the storage room (120) to a second freezing temperature. At this time, the second freezing temperature may be the internal temperature of the storage room (120) when freezing and storing the food. For example, the second freezing temperature may be a temperature corresponding to minus 18°C.
[0112] Meanwhile, the refrigeration device (100) divides the interior of the storage room into sections corresponding to short-term storage and sections corresponding to long-term storage.
[0113] The refrigeration device (100) may provide a notification when a preset condition corresponding to the entry / exit of food or the consumption of food is satisfied (S390). At this time, the preset condition corresponding to the entry / exit of food may include cases where food is introduced or released, or cases where a preset period has elapsed after food is introduced. The preset condition corresponding to the consumption of food may include cases where the location of at least one external device (200) connected to the refrigeration device (100) corresponds to the space where the refrigeration device (100) is located. When the refrigeration device (100) satisfies the preset condition corresponding to the entry / exit of food or the consumption of food, it may provide a notification corresponding to the preset condition based on food information.
[0114] According to one embodiment of the present disclosure, when food is introduced, the refrigeration device (100) may provide an incoming notification indicating that food has been introduced based on food information. The refrigeration device (100) may obtain food information when food is introduced. For example, when food is introduced, the refrigeration device (100) may obtain the type of food introduced. Additionally, the refrigeration device (100) may obtain date information regarding the food (for example, the date and time when the food was introduced). When food is introduced, the refrigeration device (100) may provide an incoming notification including the type of food introduced and the date information of the food.
[0115] According to one embodiment of the present disclosure, the refrigeration device (100) may provide a release notification based on food information indicating that food has been released when food is released. The refrigeration device (100) may obtain the date and time of release when food is released. The refrigeration device (100) may provide a release notification including the type of food released, the location of the food released within the storage room (120), the quantity of food remaining after the food is released, and the date and time of release.
[0116] According to one embodiment of the present disclosure, when food is introduced and a preset period has elapsed, the refrigeration device (100) may provide a time-limited notification indicating that the storage period of the food is imminent based on food information. At this time, the preset period may be a period during which the food can be stored in the refrigeration device (100) without spoilage. The preset period may vary depending on the type of food and the storage method. When a preset period corresponding to the type of food introduced has elapsed, the refrigeration device (100) may provide a time-limited notification including the type of food, the location of the food within the food storage room (120), and the date and time the food was introduced.
[0117] Meanwhile, the refrigeration device (100) can store food in a first-in, first-out manner. The refrigeration device (100) can provide a notification to the food that entered first, based on the time the food was inserted and the location of the food within the storage room (120). For example, if multiple breast milk storage packs or baby bottles are inserted, the refrigeration device (100) can provide a notification to the breast milk storage pack or baby bottle that entered first, so that it is released first.
[0118] The refrigeration device (100) may provide a notification of consumption for food stored in the storage room (120) based on food information when a preset condition corresponding to the consumption of food is satisfied. At this time, the consumption notification may include a notification guiding the user to consume the stored food. The refrigeration device (100) may provide a notification of consumption for food stored in the storage room (120) when the location information of at least one external device (200) connected to the refrigeration device (100) corresponds to the space where the refrigeration device (100) is located. For example, when a user is located in the space where the refrigeration device (100) is located, the location information of the user's external device (200) connected to the refrigeration device (100) may correspond to the space where the refrigeration device (100) is located. At this time, the refrigeration device (100) may provide a notification of consumption for food stored in the storage room (120) to the user. In addition, the refrigeration device (100) can also provide a release notification when the user releases food stored in the storage room (120).
[0119] Meanwhile, the refrigeration device (100) can provide a direct notification, or it can provide a notification through at least one external device (200) connected to the refrigeration device (100). The refrigeration device (100) can provide a notification through an output interface. For example, the refrigeration device (100) can output a voice notification through a speaker. Another example is that the refrigeration device (100) can display a notification through a display. The refrigeration device (100) can output a voice notification through a speaker and simultaneously display a notification through a display.
[0120] Additionally, the refrigeration device (100) can provide notifications through at least one external device (200) connected to the refrigeration device (100). The refrigeration device (100) transmits food information to the external device (200) through a communication interface, and the external device (200) can provide notifications based on the food information.
[0121] FIG. 6 is a drawing showing a notification provided by a refrigeration device (100) when a starchy food is stored in a refrigeration device (100) according to at least one embodiment of the present disclosure.
[0122] As described above, the refrigeration device (100) may provide a direct notification or provide a notification through at least one external device (200) connected to the refrigeration device (100), but the drawing is illustrated as providing a notification through at least one external device (200).
[0123] Referring to FIG. 6, an arrival notification (610) stating "Food has been received in the Kids Zone" is displayed on an external device (200) connected to a refrigeration device (100). At this time, the Kids Zone may be a name referring to a space inside a storage room (120) where starchy food is stored. However, the Kids Zone is merely one example of a name for a space inside the storage room (120) and is not limited thereto.
[0124] Additionally, FIG. 6 illustrates an intake notification (620) displayed on an external device (200) connected to a refrigeration device (100), which reads, "OOO has arrived home. Would you like to send a notification to the kids zone to consume food?" At this time, the refrigeration device (100) may provide a notification asking a second user whether to provide a notification to the first user ('OOO') who has entered the space where the refrigeration device (100) is located to consume food.
[0125] Additionally, FIG. 6 shows that the refrigeration device (100) can provide a dispatch notification (630) stating, "Food received in the kids zone on 9 / 25, 07:00 AM has been dispatched." When food is dispatched, the refrigeration device (100) can provide a dispatch notification including date information (9 / 25, 07:00 AM) for the food.
[0126] Through this, the user of the refrigeration device (100) can easily manage the consumption of starchy food for themselves as well as for other users.
[0127] FIG. 7 is a drawing showing a notification provided by a refrigeration device (100) when breast milk is stored in a refrigeration device (100) according to at least one embodiment of the present disclosure.
[0128] FIG. 7 illustrates an expiration date notification (710) displayed on an external device (200) connected to a refrigeration device (100), stating, "Breast milk received at location O on [Month] [Day] has passed [Day]. Please consume or freeze it." The refrigeration device (100) can provide an expiration date notification indicating that a preset period ('[Day] has passed') has elapsed, including location information ('Location O') within the breast milk storage chamber (120) and date information ('Month] [Day') regarding the breast milk. When a baby bottle or breast milk storage pack is placed into the storage chamber (120), the refrigeration device (100) can obtain food information corresponding to the breast milk through an image of the baby bottle or breast milk storage pack. At this time, the food information corresponding to the breast milk may include the storage location of the breast milk, the date of insertion, the quantity of breast milk, etc. Additionally, the refrigeration device (100) can identify the storage method of the breast milk by receiving user input. The refrigeration device (100) can provide an expiration date notification (710) based on food information corresponding to breast milk.
[0129] The notifications illustrated in FIGS. 6 and 7 are merely examples, and the food information and wording of the notifications included in the notifications are not limited thereto.

The food information may include information about the type of food, date information about the food, location information within the food storage room (120), and information about whether the food has been opened. The artificial intelligence model may be a model trained to identify food information corresponding to the food included in the image when an image of the food is input.
[0133] The refrigeration device (100) can identify the operating mode of the refrigeration device based on food information (S830). The operating mode may be a mode for controlling the temperature inside the storage room (120) according to the food introduced. The operating mode of the refrigeration device (100) may include a snack storage mode and a breast milk storage mode. The snack storage mode may be a mode for controlling the temperature inside the storage room (120) when the food introduced corresponds to a starchy food. The breast milk storage mode may be a mode for controlling the temperature inside the storage room (120) when the food introduced corresponds to breast milk.
[0134] The refrigeration device (100) can control the temperature inside the storage room (120) based on the identified operating mode (S840).
[0135] The refrigeration device (100) can control the internal temperature of the storage room (120) to a temperature corresponding to the snack storage mode. Specifically, the refrigeration device (100) can control the internal temperature of the storage room (120) to a first refrigeration temperature for a preset time. The first refrigeration temperature may be a temperature corresponding to a sub-zero temperature for reducing the temperature of the food in a short period of time.
[0136] When the refrigeration device (100) identifies a breast milk storage mode, it may receive user input selecting a storage method. The storage method may include short-term storage or long-term storage. When the refrigeration device (100) receives user input selecting a storage method, it may control the internal temperature of the storage chamber (120) to a temperature corresponding to the selected storage method. When the refrigeration device (100) receives user input corresponding to short-term storage, it may control the internal temperature of the storage chamber (120) to a first refrigeration temperature for a preset time and then to a preset temperature. When the refrigeration device (100) receives user input corresponding to long-term storage, it may control the internal temperature of the storage chamber (120) to a first freezing temperature for a preset time and then to a second freezing temperature.
