The electronic device 100 is a device for storing food and is a device for keeping warm or cold by adjusting the internal temperature, and includes a plate 101 and a cover 102 in the form of a lid, and includes a plate 101 and a cover 102 . ) may include a housing 103 that is an internal space formed by.

In general, food may be accommodated in the housing 103 , and the electronic device 100 may adjust the internal temperature of the housing 103 according to the type of food.

Specifically, the electronic device 100 may adjust the temperature inside the housing 103 by adjusting the temperature of the plate 101 including the Peltier element.

Hereinafter, a specific embodiment of adjusting the temperature inside the housing 103 and an embodiment in which the electronic device 100 is controlled through a Bluetooth or Wi-Fi communication method with an external device will be described in detail. do.

According to FIG. 2 , the electronic device 100 includes a weight sensor 110 , a camera 120 , a vacuum pump 130 , and a processor 140 .

The weight sensor 110 is provided on the lower side of the housing 103 and is a sensor for detecting the weight of an object placed on the plate 101 .

The weight sensor 110 includes all means for recognizing a weight when an object applies pressure on the weight sensor 110 by gravity, and may be implemented as a sensor capable of recognizing more than a preset weight. .

When more than a preset weight is detected, the weight sensor 110 may transmit a signal indicating that the weight has been detected to the processor 140 . Alternatively, the weight detection sensor 110 may transmit the detected weight level or detected weight information to the processor 140 .

The weight sensor 110 may measure a weight other than a preset weight of the plate. For example, when the preset weight of the plate is 500 g and the weight measured by the weight sensor 110 is 800 g, the weight sensor 110 may transmit weight information of 300 g to the processor 140 . Accordingly, the electronic device 100 can distinguish between a case in which food is placed on the plate and a case in which only the plate is placed on the plate 101 without food on the plate.

The camera 120 is disposed on the upper side of the housing 103 and is configured to photograph the plate 101 . The camera 120 may be disposed at a position that can secure a viewing angle to photograph the entire area of the plate 101 .

When it is identified that an object exists inside the housing 103 under the control of the processor 140 , the camera 120 may photograph the interior of the housing 103 and transmit the captured image to the processor 140 . Alternatively, the processor 140 may identify whether an object exists in the housing 103 from the image captured by the camera 120 .

An embodiment in which the processor 140 identifies the type of object based on the received captured image will be described in detail below.

The vacuum pump 130 is a device for removing gas molecules inside the housing 103 . Specifically, the vacuum pump 130 may increase the degree of vacuum inside the housing 103 by sucking, compressing, and releasing the gas inside the housing 103 to the atmosphere.

The vacuum pump 130 is a volumetric pump that uses the principle of extracting the gas in the chamber into the atmosphere by repeatedly expanding the volume of the cavity in the pump, and realizes the vacuum in the chamber by speeding up the dense fluid or rotating the blades at high speed It can be implemented as one of the adsorption type pumps that adsorb the gas in the chamber using an adsorbent material, etc.

When it is identified that an object is present in the housing 103 under the control of the processor 140 , the vacuum pump 130 may perform an operation of making the interior of the housing 103 a vacuum state. Here, the vacuum state may include not only a complete vacuum state in which gas does not exist in the housing 103 , but also a case in which the housing 103 is in a low pressure state less than or equal to a preset value.

The processor 140 controls the overall operation of the electronic device 100 .

According to an embodiment of the present disclosure, the processor 140 may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON) for processing a digital signal. Without limitation, a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), or a communication processor ( Communication processor (CP)), ARM processor, AI (Artificial Intelligence) processor may include one or more of, or may be defined by a corresponding term In addition, the processor 140 is a SoC (System on Chip) in which a processing algorithm is embedded. ), LSI (large scale integration), may be implemented in the form of a field programmable gate array (FPGA) The processor 140 may be implemented in the form of computer executable instructions (computer executable instructions) stored in a memory (not shown) By executing it, various functions can be performed.

According to an embodiment of the present disclosure, the processor 140 may identify whether an object exists in the housing 103 based on sensing data acquired through the weight detection sensor 110 .

According to an embodiment, when a weight greater than or equal to a preset value is detected, the weight detection sensor 110 may transmit a preset signal informing it to the processor 140 . When a predetermined signal is received from the weight detection sensor 110 , the processor 140 may identify that an object exists in the housing 103 .

According to another embodiment, the weight detection sensor 110 transmits the sensed data including the sensed weight information to the processor 140, and if the weight included in the received sensing data is greater than or equal to a preset value, the processor 140 may It can be identified that an object exists inside the housing 103 .

According to another embodiment, the processor 140 may identify whether an object exists in the housing 103 based on the captured image captured by the camera 120 without using the weight detection sensor 110 . there is.

When it is identified that an object exists inside the housing 103 , the processor 140 may control the vacuum pump 130 so that the inside of the housing 103 is in a vacuum state. Specifically, the vacuum pump 130 removes the gas inside the housing 103 by sucking and compressing the gas inside the housing 103 under the control of the processor 140 and releasing it into the atmosphere to remove the gas inside the housing 103 . can be brought into a vacuum. Here, the vacuum state may include not only a complete vacuum state in which gas does not exist in the housing 103 , but also a case in which the housing 103 is in a low pressure state less than or equal to a preset value. In the case of vacuum, since the gas density inside the housing 103 is low, it becomes an environment in which microorganisms are difficult to reproduce, so that the freshness of the food can be maintained relatively high.

The processor 140 may identify the type of object existing in the housing 103 based on the captured image acquired through the camera 120 . Specifically, the processor 140 may determine the type of food by performing object detection from the captured image obtained through the camera 120 . Specifically, the processor 140 may detect a feature point of an object in a captured image, analyze a distribution of the feature points, and perform object detection by analyzing an edge of the object. Here, the object detection includes detection of the object type as well as the existence of the object.

For example, the processor 140 may identify whether the type of the object existing inside the housing is noodles, bread, rice, or the like.

In addition, the processor 140 may control the communication interface (not shown) to transmit information about the type of the object and the captured image acquired through the camera 120 to the user terminal (not shown). When feedback information on the type of object is received from the user terminal, the processor 140 may adjust the temperature inside the housing based on the received feedback information. In other words, the processor 140 may receive the type of the object identified by the processor 140 from the user by receiving feedback information on the type of the object. Accordingly, accuracy of object type information may increase. However, the present invention is not limited thereto, and the processor 140 may perform the following procedure without receiving user feedback information.

The processor 140 may adjust the temperature inside the housing 103 based on the type of the identified object. Specifically, the processor 140 controls the temperature of the Peltier element included in the plate 101 provided on the lower side of the housing 103 based on the type of the identified object, thereby controlling the temperature inside the housing 103 . Can be adjusted. The Peltier device is a device in which two different types of metal are joined, and then the junction is cooled or heat is generated when an electric current is passed through it, and it can be used to adjust the temperature. In other words, the adjustment of the temperature inside the housing 103 means that the temperature of the plate 101 is adjusted.

On the other hand, the plate 101 may be implemented with a conductive material, and accordingly, the changed temperature of the Peltier element may be transmitted to the plate 101 . The Peltier element may be disposed under the plate 101, but is not limited thereto. In addition, it is preferable that the plate for holding food is also implemented with a conductive material. Accordingly, the changed temperature of the Peltier element is transmitted to the plate, and the food can be warm or cold.

Since the internal state of the housing 103 is a vacuum state in which gas molecules are small, the processor 140 may bring the internal temperature of the housing 103 to the target temperature relatively quickly compared to a non-vacuum state.

Meanwhile, the processor 140 may be communicatively connected to an external device (not shown) and may adjust the internal temperature of the housing 103 based on a signal received from the external device.

Specifically, when a signal is received from the external device through the communication interface, the processor 140 may identify the type of the external device. For example, the processor 140 may receive a signal from an external device through a Wi-Fi module or a Bluetooth module. The received signal may include not only a control command but also identification information of an external device. Here, the identification information may include at least one of an IP address, a MAC address, a serial number, a product number, a product name, and manufacturer information of the external device. Accordingly, the processor 140 may identify the type of the external device based on identification information included in the signal received from the external device.

The processor 140 may predict the type of object to be accommodated in the housing 103 based on the identified type of the external device, and may adjust the temperature inside the housing 103 based on the predicted type of the object.

For example, it is assumed that the type of the external device is an oven or a microwave oven. In general, since an oven or microwave oven is a device used to increase the temperature of food, the processor 140 predicts that the type of object requiring warmth will be accommodated in the housing 103 when receiving a signal from the oven or microwave oven. and increase the temperature inside the housing 103 .

Meanwhile, the external device may transmit a preset signal to the electronic device 100 at a time such as when the external device operates or when the operation of the external device ends. Here, the preset signal may be a signal including identification information of an external device as described above. For example, when the user presses the operation button of the microwave oven, the microwave oven may transmit a preset signal to the electronic device 100 , and the processor 140 may increase the temperature inside the housing 103 .

According to an embodiment, when the user presses the operation button of the microwave oven, the microwave oven may inquire whether to use the electronic device 100 . For example, the microwave oven may provide an inquiry “Would you like to use a smart plate (an example of an electronic device product name)?” through the provided speaker or display. When user feedback for this is input to the microwave oven, the microwave oven may transmit the input user feedback information to the electronic device 100 . The electronic device 100 may determine whether to adjust the temperature inside the housing 103 based on the received user feedback information.

However, the present invention is not limited thereto, and when the user presses the operation button of the microwave oven, the microwave oven transmits a signal to the user terminal (eg, a smartphone), and the user terminal transmits a signal to the “smart plate (electronic Would you like to use an example of the device product name)?” Even when an external device such as a microwave oven is not provided with a speaker or a display, the user terminal may inquire whether to use the electronic device 100 to the user.

As another example, it is assumed that the processor 140 receives a preset signal from a refrigerator rather than an oven or a microwave oven, and the refrigerator is a model that includes a camera to identify the type of an object stored in the refrigerator. In this case, when the user takes out food from the refrigerator, the refrigerator may identify which food has been moved to the outside. The refrigerator may transmit information about the food moved to the outside, that is, information on the type of the object to the electronic device 100 . The electronic device 100 may adjust the temperature inside the housing 103 based on the received information on the type of the object.

As described above, when food stored in the refrigerator is moved to the outside, the refrigerator may inquire whether to use the electronic device 100 . For example, the refrigerator may provide an inquiry “Would you like to use a smart plate (an example of an electronic device product name)?” through the provided speaker or display. When user feedback for this is input to the refrigerator, the refrigerator may transmit the input user feedback information to the electronic device 100 . The electronic device 100 may determine whether to adjust the temperature inside the housing 103 based on the received user feedback information.

Information on whether a warming function or a cooling function for each type of external device may be stored in the memory, and the processor 140 may determine whether to increase or decrease the internal temperature of the housing 103 based on such information. there is. Meanwhile, such information may be pre-stored in a memory or received from an external server.

Meanwhile, the processor 140 may control an Ultra Violet (UV) LED device provided on the upper side of the housing 103 to sterilize the object based on the identified object type.

Specifically, the processor 140 may sterilize food by turning on a UV lamp provided with a plurality of UV LED elements, and may adjust the amount of ultraviolet light according to the type of food. For example, the processor 140 may control the UV LED device to increase the amount of UV light in the case of a food type that is relatively easily perishable, and may increase the time the UV light is emitted. On the other hand, the processor 140 may control the UV LED device to relatively reduce the amount of UV light in the case of a food type that is relatively less perishable, and may also reduce the time for which UV light is emitted. Information on the degree of spoilage corresponding to the type of food may also be stored in the memory, and the processor 140 may adjust the amount of UV light using the stored information.

In addition, the processor 140 may control the UV LED device to emit ultraviolet rays at a preset period.

Meanwhile, the processor 140 may adjust the internal temperature of the housing 103 based on a control signal received from the user terminal even when an object is not identified on the plate 101 .

Specifically, when the control information for adjusting the temperature inside the housing 103 is received from the user terminal through the communication interface while the object inside the housing 103 is not identified, the processor 140 receives the control information based on the received control information. Thus, the temperature inside the housing 103 can be adjusted.

For example, when it is required to quickly keep food warm, the user may turn on the electronic device 100 through the user terminal and set the target temperature inside the housing 103 . In this case, the processor 140 may receive a turn-on command and control information including target temperature information from the user terminal, and adjust the temperature inside the housing 103 based on the received target temperature information. After the temperature inside the housing 103 is adjusted, the user may place the food on the plate 101 of the electronic device 100 to keep the food warm. In this case, after food is placed on the plate 101, the type of food is identified through a process such as photographing, and the temperature inside the housing 103 is adjusted based on the identified food type. The temperature inside can be adjusted. Accordingly, the temperature of the food may also reach the intended target temperature relatively quickly.

On the other hand, when the type of the object is identified based on the captured image obtained through the camera 120, the processor 140 determines the type of the identified object based on target temperature information for each type of object stored in the memory (not shown). A corresponding target temperature may be identified. Thereafter, the processor 140 may adjust the internal temperature of the housing 103 based on the target temperature.

For example, when the type of object is identified as noodles, the processor 140 may identify a target temperature corresponding to the noodles from target temperature information for each type of object stored in the memory. Thereafter, the processor 140 may adjust the temperature inside the housing 103 to reach a target temperature corresponding to the noodles.

In addition, the processor 140 may identify the target temperature based on the type of the object, and when the internal temperature of the housing 103 reaches the target temperature, the processor 140 may perform a constant temperature operation to maintain the target temperature. For example, when the target temperature corresponding to the noodle is 30 degrees, the processor 140 controls the Peltier element so that the temperature inside the housing 103 reaches 30 degrees, and the temperature inside the housing 103 is 30 degrees. Once reached, a constant temperature operation can be performed to maintain the temperature at 30 degrees without further increasing the temperature.

Meanwhile, the processor 140 may identify whether the temperature inside the housing 103 has reached 30 degrees based on sensing data sensed through the temperature sensor provided in the electronic device 100 .

Specifically, the processor 140 may adjust the internal temperature of the housing 103 so that the internal temperature of the housing 103 reaches a target temperature based on the sensed data acquired by the temperature sensor. For example, when the temperature obtained by the temperature sensor is equal to or less than the target temperature, the processor 140 may increase the internal temperature of the housing 103 . Alternatively, when the temperature obtained by the temperature sensor is the target temperature, the processor 140 may perform a constant temperature operation without increasing the internal temperature of the housing 103 any longer.

Meanwhile, the electronic device 100 may include a built-in battery. Accordingly, the electronic device 100 may receive power through the outlet or may receive power from the built-in battery. For example, even in an outdoor environment in which power cannot be supplied through an outlet, the electronic device 100 may be operated by receiving power from the built-in battery.

Referring to FIG. 3 , the electronic device 100 includes a weight sensor 110 , a camera 120 , a vacuum pump 130 , a processor 140 , a communication interface 150 , a memory 160 , and a temperature sensor 170 . includes A detailed description of the portion overlapping with the configuration shown in FIG. 2 among the configuration shown in FIG. 3 will be omitted.

The processor 140 controls the overall operation of the electronic device 100 using various programs stored in the memory 160 .

The processor 140 includes a RAM, a ROM, a main CPU, first to n interfaces, and a bus. In this case, the RAM, ROM, main CPU, first to n interfaces, etc. may be connected to each other through a bus.

The ROM stores an instruction set for booting the system, and the like. When a turn-on command is input and power is supplied, the main CPU copies the O/S stored in the memory 160 to the RAM according to the command stored in the ROM, and executes the O/S to boot the system. When booting is completed, the main CPU copies various application programs stored in the memory 160 to the RAM, and executes the application programs copied to the RAM to perform various operations.

The main CPU accesses the memory 160 and performs booting using the O/S stored in the memory 160 . In addition, the main CPU performs various operations using various programs, contents, data, etc. stored in the memory 160 .

The first to n interfaces are connected to the various components described above. One of the interfaces may be a network interface connected to an external device through a network.

The communication interface 150 including circuitry is a component capable of communicating with an external device or a user terminal. Specifically, the identification information and control signal of the external device may be received from the external device through the communication interface 150 , or the identification information and control signal of the user terminal may be received from the user terminal. Also, the communication interface 150 may receive target temperature information for each type of object from an external server.

In this way, the Internet of Things may be performed by transmitting and receiving control commands through the device-to-device network.

The memory 160 may be implemented in the form of a memory embedded in the electronic device 100 or may be implemented in the form of a memory that is detachable from the electronic device 100 according to the purpose of data storage. For example, data for driving the electronic device 100 is stored in a memory embedded in the electronic device 100 , and data for an extended function of the electronic device 100 is detachable from the electronic device 100 . It can be stored in any available memory. Meanwhile, in the case of a memory embedded in the electronic device 100 , a volatile memory (eg, dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM), etc.), non-volatile memory (non-volatile memory) ( Examples: one time programmable ROM (OTPROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (such as NAND flash or NOR flash, etc.) ), a hard drive, or a solid state drive (SSD), and in the case of a removable memory in the electronic device 100, a memory card (eg, compact flash (CF), SD ( secure digital), Micro-SD (micro secure digital), Mini-SD (mini secure digital), xD (extreme digital), MMC (multi-media card), etc.), external memory that can be connected to the USB port (e.g., USB memory) and the like.

According to an embodiment, the memory 160 may store target temperature information for each type of object, information on a degree of corruption according to the type of object, and the like.

The temperature sensor 170 is a sensor for measuring the temperature inside the housing 103 . Specifically, the temperature sensor 170 may be provided around the plate to measure the temperature of the plate. In addition, the temperature sensor 170 may be provided on the upper end of the housing 103 (eg, provided on the cover 102) to measure the temperature of the upper end of the housing 103. The temperature sensor 170 is measured temperature information may be transmitted to the processor 140 .

The display 180 is configured to display various contents or information. In particular, the display 180 may display information such as a target temperature and a current temperature.

The display 180 is a liquid crystal display (LCD), an organic light-emitting diode (OLED), a liquid crystal on silicon (LCoS), a digital light processing (DLP), a quantum dot (QD) display panel, a quantum dot light- (QLED) emitting diodes) and micro light-emitting diodes (LEDs) may be implemented in various types of displays.

The display 180 may be implemented in the form of a touch screen that forms a layer structure with the touch pad. Here, the touch screen may be configured to detect a touch input position and area as well as a touch input pressure.

The weight sensor 110 is a lower side of the housing 103 and may be disposed above the plate 101 . Accordingly, the weight sensor 110 may detect the weight of the food placed on the plate 101 .

The camera 120 is an upper side of the housing 103 , and may be disposed above the cover 102 . Accordingly, the camera 120 can secure a viewing angle for photographing the food in the plate on the plate 101 as a whole.

The vacuum pump 130 is an upper side of the housing 103 , is disposed on the upper side of the cover 102 , and has a configuration included in the cover 102 .

Although the display 180 is illustrated as being provided on the lower side of the electronic device 100 according to FIG. 4 , this is only an example.

Meanwhile, the display 180 may display information such as a currently operating mode, including an icon for changing the current state and mode.

For example, the display 180 may include a power button, a mode change button, a keep warm mode icon, a cool mode icon, a UV mode icon, a lock mode icon, a Wi-Fi and Bluetooth mode icon, a battery icon, and the like. Here, the mode change means a change of the keep warm mode, the cool mode, and the UV mode.

The warm mode icon, the cool mode icon, and the UV mode icon may be implemented as icons of different colors to be easily distinguished by the user. For example, the warm mode icon may be displayed in red, the cool mode icon may be displayed in blue, and the UV mode icon may be displayed in green.

The Wi-Fi and Bluetooth mode icon may be an icon indicating that a current Wi-Fi or Bluetooth connection is possible.

Also, the battery icon may be an icon indicating a charging state of a built-in battery included in the electronic device 100 .

Meanwhile, it goes without saying that the description of the physical location of the configuration shown in FIG. 4 is only an example and may be changed in various ways to implement the electronic device 100 . Likewise, it goes without saying that icons included in the display 180 may also be reduced or added differently from FIG. 4 .

Referring to FIG. 5 , it is assumed that the electronic device 100 in the home, the oven, and the induction are connected to one access point and are connected to the network. In this case, it is possible to transmit and receive a mutual control signal between a plurality of devices by the access point.

For example, when the user presses an operation button of the oven or when the operation of the oven ends, the oven may transmit a preset signal to the electronic device 100 . Here, the preset signal may include information indicating that the operation of the oven has started or ended and identification information of the oven.

The electronic device 100 may identify that the external device is an oven based on the received preset signal, and may increase the internal temperature of the housing 103 . Since the characteristic of an oven device is that it is used to increase the temperature of food, the electronic device 100 may increase the internal temperature of the housing 103 when it is identified that the external device is an oven.

Information on whether a warming function or a cooling function is used for each type of external device may be stored in the memory 160, and the electronic device 100 determines whether the temperature inside the housing 103 is increased or decreased based on such information. can decide whether

As another example, when the user presses the operation button of the induction or when the operation of the induction is terminated, the induction may transmit a preset signal to the electronic device 100 . Here, the preset signal may include information indicating that the operation of the induction has started or ended and identification information of the oven.

The electronic device 100 may identify that the external device is induction based on the received preset signal and increase the temperature inside the housing 103 .

Meanwhile, the electronic device 100 may receive a signal from the user terminal.

Specifically, the electronic device 100 receives control information for adjusting the temperature inside the housing 103 from the user terminal through the communication interface 150 even while the object is not identified inside the housing 103 , The temperature inside the housing 103 may be adjusted based on the obtained control information.

For example, when it is required to quickly keep food warm, the user may turn on the electronic device 100 through the user terminal and set the target temperature inside the housing 103 . For example, the user may purchase food from the outside and allow the electronic device 100 to reach the target temperature in advance through the user terminal.

In this case, the electronic device 100 may receive a turn-on command and control information including target temperature information from the user terminal, and may adjust the internal temperature of the housing 103 based on the received target temperature information. After the temperature inside the housing 103 is adjusted, the user may place the food on the plate 101 of the electronic device 100 to keep the food warm. In this case, after food is placed on the plate 101, the type of food is identified through a process such as photographing, and the temperature inside the housing 103 is adjusted based on the identified food type. The temperature inside can be adjusted. Accordingly, the temperature of the food may also reach the intended target temperature relatively quickly.

Referring to FIG. 6 , the electronic device 100 may set the temperature of the plate 101 based on a preset signal received through a user terminal or an external device such as an oven ( S610 ). In other words, it is assumed that the electronic device 100 is turned on and the plate 101 is set based on an external signal.

Thereafter, when food is placed on the plate 101 ( S620 ), the electronic device 100 may identify the food by the weight sensor 110 and the camera 120 and further determine the type of food.

The electronic device 100 may determine whether to perform the HOT function or the COOL function based on target temperature information for each type of food stored in the memory 160 . Accordingly, the electronic device 100 may operate a HOT or COOL function (S640).

The electronic device 100 may identify whether the temperature of the plate 101 has reached the target temperature based on the temperature data sensed by the temperature sensor 170 (S640).

When it is identified that the temperature of the plate 101 has not reached the target temperature (S640-N), the electronic device 100 performs a HOT or COOL function to determine whether the temperature of the plate 101 has reached the target temperature again. can be identified.

When the temperature of the plate 101 reaches the target temperature (S640-Y), the electronic device 100 may perform a constant temperature operation to maintain the target temperature (S650).

The electronic device 100 may identify whether an object exists in the housing 103 ( S710 ). Specifically, the electronic device 100 may identify whether an object exists in the housing 103 through the weight sensor 110 .

When it is identified that an object exists inside the housing 103 , the electronic device 100 may control the inside of the housing 103 to be in a vacuum state ( S720 ). Specifically, the electronic device 100 may control the vacuum pump so that the inside of the housing is in a vacuum state. Here, the vacuum state may include not only a complete vacuum state in which gas does not exist in the housing 103 , but also a case in which the housing 103 is in a low pressure state less than or equal to a preset value.

The electronic device 100 may identify the type of object existing inside the housing 103 ( S730 ).

According to an example, the electronic device 100 may identify the type of object by performing object detection based on a captured image captured by the camera 120 .

Thereafter, the electronic device transmits the captured image of the object and information on the type of the object to the user terminal, and when feedback information on the type of the object is received from the user terminal, compares the detected object type with the received feedback information, Finally, the type of object can be determined.

Meanwhile, the electronic device 100 may control an Ultra Violet (UV) LED device provided on the upper side of the housing 103 to sterilize the object based on the type of the object.

The electronic device 100 may adjust the temperature inside the housing 103 based on the identified type of object ( S740 ). Specifically, the electronic device 100 may control the temperature of the Peltier element included in the plate 101 provided on the lower side of the housing 103 based on the identified object type.

For example, when the type of the object is identified based on the captured image of the object, the electronic device 100 identifies a target temperature corresponding to the type of the identified object based on previously stored target temperature information for each type of object, The temperature inside the housing 103 may be adjusted based on the temperature.

Specifically, the electronic device 100 may adjust the internal temperature of the housing 103 so that the internal temperature of the housing 103 reaches a target temperature based on the sensed temperature data.

Thereafter, when the temperature inside the housing 103 reaches the target temperature, the electronic device 100 may perform a constant temperature operation to maintain the target temperature.

On the other hand, when the electronic device 100 receives control information for adjusting the temperature inside the housing 103 from the user terminal even when an object is not identified inside the housing 103, based on the received control information, the housing ( 103) The internal temperature can be adjusted.

Also, when a signal is received from the external device, the electronic device 100 identifies the type of the external device, predicts the type of object to be accommodated in the housing 103 based on the identified external device type, and predicts the predicted type of the external device. The temperature inside the housing 103 may be adjusted based on the type of object.

The electronic device 100 may operate by receiving power from a built-in battery provided in the electronic device 100 . However, the present invention is not limited thereto, and of course, it may be operated by receiving power through an outlet.
