[0087] When the server (3) receives information regarding operation or status from the cooking device (1) and the home appliance (10), it updates the stored information regarding operation or status of the cooking device (1) and the home appliance (10) and transmits the updated information regarding operation and status of the cooking device (1) and the home appliance (10) to the user device (2) via a network. Here, updating information may include various operations that change existing information, such as adding new information to existing information or replacing existing information with new information.

[0088] The home appliance (10) can obtain various information from a cooking device (1), other home appliances, a user device (2), or a server (3) and provide the obtained information to the user. For example, the home appliance (10) can obtain information related to the functions of the home appliance (10) (e.g., recipes, laundry methods, etc.) and various environmental information (e.g., weather, temperature, humidity, etc.) from the server (3) and output the obtained information through a user interface.

[0089] The home appliance (10) can operate according to control commands received from the cooking device (1), other home appliances, user device (2), or server (3). For example, if the cooking device (1) and the home appliance (10) have obtained prior approval from the user to operate according to control commands from the server (3) even without user input, the cooking device (1) and the home appliance (10) can operate according to control commands received from the server (3). Here, the control commands received from the server (3) may include, but are not limited to, control commands entered by the user through the user device (2) or control commands based on pre-set conditions.

[0090] The user device (2) can transmit information about the user to the cooking device (1), home appliance (10), or server (3) through a communication module. For example, the user device (2) can transmit information about the user's location, health status, preferences, schedule, etc. to the server (3). The user device (2) can transmit information about the user to the server (3) upon the user's prior approval.

[0091] A cooking device (1), a home appliance (10), a user device (2), or a server (3) may determine control commands using technology such as artificial intelligence. For example, the server (3) may receive information regarding the operation or status of the cooking device (1) or the home appliance (10), or receive information regarding the user of the user device (2), process it using technology such as artificial intelligence, and transmit the processing result or control command to the cooking device (1), the home appliance (10), or the user device (2) based on the processing result.

[0121] The light from the second light-emitting diode that is lit among the plurality of second light-emitting diodes can pass through the top plate (110). Accordingly, the user can see the light from the second light-emitting diode that has passed through the top plate.

[0122] The second output interface (123) can display the entire cooking area. The second output interface (123) can display the border of the entire cooking area of ​​the cooking device.

[0123] The second output interface (123) can display guidance information regarding the possibility of heating a container mounted in the first area of ​​the top plate (110).

[0124] The second output interface (123) can display a recommended cooking area that recommends a cooking area for a container to be cooked.

[0125] As shown in FIG. 3, a coil portion (130) may be provided in the space that is the lower part of the top plate (110) and the interior of the main body (100).

[0126] The coil section (130) may include a plurality of coils. The plurality of coils may have the same size and number of turns.

[0127] Multiple coils of the coil section (130) may differ in size and number of turns, and accordingly, their maximum power levels may differ.

[0128] Each coil of the coil section (130) forms a magnetic field when current is supplied, and the container is heated by the magnetic field formed at this time. The container heating principle of all coils that heat the container may be the same. The container heating principle of the first coil (131) is described.

[0129] The first coil (131) can receive a high-frequency current. When a high-frequency current is supplied to the wound wire of the first coil (131), magnetic field lines (ML) can be formed in the first coil (131). Here, the formation of magnetic field lines (ML) in the coil (130) includes the formation of a magnetic field passing through the inside of the first coil (131) according to Ampere's law.

[0130] The magnetic field generated in the first coil (131) by the alternating current applied to the first coil (131) also changes over time. That is, when the time-varying magnetic field passes through the interior of the first coil (131), a current rotating around the magnetic field is generated inside the bottom surface of the container (200).

[0131] Here, the current rotating around the magnetic field is a current formed by a voltage generated in a direction that opposes the change in the magnetic field of the first coil (131), and is called an eddy current (EC). The bottom surface of the container (200) can be heated by such an eddy current (EC).

[0132] In the cooking device (1), since the container (200) itself acts as a heat source, the material of the container (200) may be a metallic iron, stainless steel, nickel, etc., having a resistance of a certain level or higher. The efficiency corresponding to the heating performance of such a container (200) may vary depending on the material of the container.

[0133] In other words, when an eddy current (EC) flows through a container (200) having electrical resistance, heat is generated according to Ohm's law, and the container (200) can be heated. Here, the phenomenon in which a current is induced by a magnetic field that changes over time is called the electromagnetic induction phenomenon.

[0134] In this way, the cooking device (1) can selectively supply current to one or more of the multiple coils and heat the container (200) using the magnetic field generated by one or more of the coils.

[0135] The control parameters of each coil may include current application time, current intensity, and / or frequency.

[0136] The cooking device (1) is provided in the internal space of the main body (100) and may further include a circuit board (150) connected to a user interface (120), a second output interface (123), and a plurality of coils (130).

[0137] A circuit board (150) may include a coil driving unit (151) comprising a plurality of driving circuits connected to each of a plurality of coils, a plurality of current sensors (152) each connected to a plurality of driving circuits and detecting a current flowing through each of a plurality of driving circuits, and a control unit (160) that controls a plurality of driving circuits based on the current detected by the plurality of current sensors.

[0138] The configuration of the plurality of driving circuits of the coil driving unit (151) may be identical to one another. A first driving circuit for driving the first coil among the plurality of coils is described with reference to FIG. 4.

[0139] As shown in FIG. 4, the first driving circuit of the coil driving unit (151) can adjust the magnitude of the current applied to the first coil (131) based on the power level of the first coil (131).

[0140] The power level can be selected by the user or determined by recipe information. The higher the power level, the larger the magnetic field generated by the first coil (131), allowing the container (200) to be heated faster and to a higher temperature.

[0141] The first driving circuit can be connected to a rectifier that receives power from an external commercial power source, removes noise, and rectifies, and a smoothing section that removes ripple from the rectified power.

[0142] The first driving circuit includes a first switching unit (Q1) and a second switching unit (Q2) that receive an operation signal from a control unit (160, see FIG. 5), and first and second capacitors (C1, C2) connected in parallel with the first switching unit (Q1) and the second switching unit (Q2).

[0143] The first switching unit (Q1) and the second switching unit (Q2) each include a gate terminal connected to the control unit (160), and can be turned on by receiving a turn-on signal through this gate terminal or turned off by receiving a turn-off signal.

[0144] Here, the first switching unit (Q1) and the second switching unit (Q2) can be turned on alternately. That is, when the first switching unit (Q1) is turned on, the second switching unit (Q2) is turned off, and when the first switching unit (Q1) is turned off, the second switching unit (Q2) can be turned on.

[0145] The first coil (131) forms a resonant circuit together with the first and second capacitors (C1, C2). The current (IL1) of the first coil (131) resonates according to a constant period. The first coil (131) generates a high-frequency magnetic field using the operating frequency of the first switching unit (Q1) and the second switching unit (Q2).

[0146] The first driving circuit can supply a current with a changing direction to the first coil (131) according to the turn-on and turn-off operations of the first switching unit (Q1) and the second switching unit (Q2).

[0147] That is, when the first switching unit (Q1) is turned on and the second switching unit (Q2) is turned off, a driving current in the first direction is supplied to the first coil (131), and when the first switching unit (Q1) is turned off and the second switching unit (Q2) is turned on, a driving current in the second direction is supplied to the first coil (131).

[0148] The first driving circuit can generate a gate signal to turn on and turn off the first switching unit (Q1) and the second switching unit (Q2) according to the command of the control unit (160).

[0149] There are multiple current sensors (152), each of which can be connected to a plurality of coils. Each current sensor (152) can detect the current flowing through the coil and transmit current information regarding the detected current to the control unit (160).

[0150] For example, the current sensor (152) may include a current transformer (CT) that decreases in proportion to the magnitude of the current supplied to the coil and an ammeter that detects the magnitude of the proportionally reduced current.

[0151] As another example, the current sensor (152) may include a shunt resistance connected to a coil and a measuring part (not shown) that measures the voltage drop occurring in the shunt resistance.

[0229] The control unit (160) can identify whether the mounted container is a heatable container or a non-heatable container based on detection information detected by the container identification sensor (140).

[0230] For example, the control unit (160) can identify whether the mounted container is a heatable container or a non-heatable container based on current information received from a plurality of current sensors (152).

[0231] More specifically, the control unit (160) controls the power level of at least one coil provided in the cooking area of ​​the container to a reference power level, and when current is received from a current sensor connected to at least one coil, recognizes whether the received current is less than the reference current, and if the received current is less than the reference current, identifies the container as a container that cannot be heated.

[0232] The control unit (160) can also identify the mounted container as a container that cannot be heated if the detected current is less than the reference current even after the time for operating at least one coil at the reference power level has reached the target time.

[0233] The control unit (160) can also identify a container as a container that cannot be heated when the number of times it is identified as a container that cannot be heated reaches a reference number.

[0234] The control unit (160) can identify a mounted container as a heatable container based on the fact that the current detected by a current sensor connected to at least one coil is greater than or equal to a reference current.

[0235] As another example, the control unit (160) may apply signals of multiple frequencies to the first switching unit and the second switching unit at regular time intervals for each driving circuit of the coil driving unit, and compare the phase of the current detected while the first switching unit and the second switching unit are operating for each driving circuit with the phase of the voltage when the first switching unit is turned on to identify whether the container can be heated for each driving circuit.

[0237] As another example, the control unit (160) can also recognize the heating potential of the container for each driving circuit based on the RMS (Root Mean Square) current rather than the peak current.

[0238] If a capacitance sensor is provided, the control unit (160) can identify whether the mounted container can be heated based on the change value of the capacitance detected by the capacitance sensor.

[0239] The control unit (160) can control the first output interface (122) to output guidance information regarding the possibility of heating the container when the container is recognized as a container capable of heating.

[0240] The control unit (160) may also transmit guidance information regarding the possibility of heating a container mounted on the top plate of the cooking device to a user device or home appliance.

[0253] As illustrated in FIG. 7, the control unit (160) can control the second display panel to display a guide image (GL) for guiding the possibility of heating the container at a position corresponding to the edge of the cooking area of ​​the container among the positions of the second display panel.

[0254] A guidance image (GL) for indicating the possibility of heating the container may be displayed around the container, that is, at a location corresponding to the cooking area of ​​the container. The guidance image (GL) for indicating the possibility of heating the container may be an image corresponding to the shape and size of the container.

[0255] When the second output interface is a plurality of second light-emitting diodes, the control unit (160) can identify at least one second light-emitting diode among the plurality of second light-emitting diodes that is located at a position in the container, and control at least one second light-emitting diode so that the identified at least one second light-emitting diode emits light.

[0257] In this way, the cooking device of the present embodiment can display guidance information regarding whether a container mounted on the cooking device can be heated through a second output interface, thereby enabling the user to easily recognize whether a container mounted on the cooking device can be heated.

[0258] The control unit (160) can recognize identification information of a container based on detection information received from the container identification sensor (140) and control the storage of the recognized identification information of the container.

[0260] The control unit (160) recognizes the location information of the container on which the container is mounted based on the detection information received from the container identification sensor (140), recognizes the cooking area of ​​the container based on the recognized location information of the container, and can store the identification information of the container by matching the recognized cooking area with the container.

[0261] The control unit (160) can acquire cooking history information by learning the identification information of the recognized cooking area and container.

[0262] The recognition configuration of the container identification information and the container location information will be explained in more detail with reference to FIGS. 8 and 9.

[0263] As shown in FIG. 8, the first region (EL) of the top plate of the cooking device may have X, Y coordinate information.

[0264] The first vertex among the vertices of the first region of the top plate may be the origin coordinates (X0, Y0) of the X, Y coordinates. The second vertex among the vertices of the first region of the top plate that is diagonally opposite to the first vertex may be the endpoint coordinates (Xn, Ym) of the X, Y coordinates. Here, n and m are natural numbers and may be the same or different.

[0265] For example, the endpoint coordinates (Xn, Ym) of the first region of the top plate may be (X100, Y100), but are not limited thereto.

[0266] An example of a configuration for recognizing identification information of a container and a cooking area (PL) of a container using multiple current sensors (152) is described.

[0267] The control unit (160) can recognize at least one current sensor that detects a current greater than a reference current based on current information received from a plurality of current sensors (152), recognize location information of at least one coil connected to the recognized at least one current sensor, recognize location information of a container based on the location information of the recognized at least one coil, and recognize a cooking area of ​​a container based on the location information of the recognized container.

[0268] Each of the multiple coils may have X and Y values ​​based on the arrangement order in which they are placed inside the main body. For example, the first coil placed closest to the origin coordinates (X0, Y0) of the top plate may have the coordinate value (X1, Y1), the second coil placed closest to the first coil in the X-axis direction may have the coordinate value (X2, Y1), the third coil placed closest to the first coil in the Y-axis direction may have the coordinate value (X1, Y2), and the p-th coil placed closest to the end point coordinates (Xn, Ym) may have the coordinate value (Xn, Ym). Here, p in the p-th coil may be a number corresponding to n×m.

[0269] The control unit (160) can recognize the X value of the X coordinate and the Y value of the Y coordinate as position information of the recognized coil. Here, the position information of the recognized coil may be position information of the container. That is, the control unit (160) can recognize coordinate information as position information of the container.

[0270] When there are multiple current sensors that detect a current greater than the reference current, the control unit (160) can obtain multiple coordinate information corresponding to each of the position information of the multiple coils, and can recognize multiple X values ​​and multiple Y values ​​from the multiple coordinate information.

[0271] The control unit (160) can recognize the shape of the container based on the position information of one recognized coil.

[0272] More specifically, the control unit (160) recognizes the minimum X value and the maximum X value among the recognized X-coordinate X values, and recognizes the minimum Y value and the maximum Y value among the Y-coordinate Y values, and can recognize the shape of the container based on the recognized minimum X value, maximum X value, minimum Y value, and maximum Y value.

[0273] Here, recognizing the minimum X value, maximum X value, minimum Y value, and maximum Y value may include recognizing coordinate information corresponding to the edge of the recognized container, and may include recognizing coordinate information corresponding to the edge of the cooking area of ​​the recognized container.

[0274] The control unit (160) recognizes the amount of change in the minimum Y value and the amount of change in the maximum Y value between the recognized minimum X value and the maximum X value, and can recognize the shape of the container based on the amount of change in the recognized minimum Y value and the amount of change in the maximum Y value.

[0275] The control unit (160) can recognize the amount of change of the minimum X value and the amount of change of the maximum X value between the recognized minimum Y value and the maximum Y value, and it is also possible to recognize the shape of the container based on the amount of change of the recognized minimum X value and the amount of change of the recognized maximum X value.

[0276] The control unit (160) may also recognize the shape of the container based on at least one of the change amount of the recognized minimum Y value, the change amount of the recognized maximum Y value, the change amount of the recognized minimum X value, and the change amount of the recognized maximum X value.

[0277] The control unit (160) can recognize the size of the container based on the recognized maximum X value, minimum X value, maximum Y value, and minimum Y value.

[0278] As illustrated in FIG. 8, the control unit (160) lists the minimum Y values ​​for each X value in order of magnitude from the minimum X value (Xa) to the maximum X value (Xb) among the coordinate values ​​for the cooking area (PL), recognizes a first change pattern for the amount of change of the minimum Y values ​​for each listed X value, lists the maximum Y values ​​for each X value in order of magnitude from the minimum X value (Xa) to the maximum X value (Xb), and recognizes a second change pattern for the amount of change of the maximum Y values ​​for each listed X value.

[0279] The control unit (160) can recognize the shape of the container as a square shape based on the fact that the first change pattern is recognized as a pattern with no change in minimum Y value and the second change pattern is recognized as a pattern with no change in maximum Y value.

[0280] The control unit (160) lists the minimum X values ​​for each Y value in order of magnitude from the minimum Y value (Ya) to the maximum Y value (Yb), recognizes a third change pattern for the amount of change of the minimum X values ​​for each listed Y value, lists the maximum X values ​​for each Y value in order of magnitude from the minimum Y value (Ya) to the maximum Y value (Yb), and recognizes a fourth change pattern for the amount of change of the maximum X values ​​for each listed Y value.

[0281] The control unit (160) can recognize the shape of the container as a square shape based on the fact that the third change pattern is recognized as a pattern with no change in minimum X value and the fourth change pattern is recognized as a pattern with no change in maximum X value.

[0282] The control unit (160) can recognize the shape of the container as a square shape based on the first, second, third, and fourth change patterns.

[0283] When the shape of the container is recognized as a square shape, the control unit (160) recognizes a first length of the container based on the difference between a minimum X value (Xa) and a maximum X value (Xb), recognizes a second length based on the difference between a minimum Y value (Ya) and a maximum Y value (Yb), and recognizes the size of the container based on the recognized first and second lengths. Here, the size of the container may include the area of ​​the container.

[0284] As illustrated in FIG. 9, the control unit (160) recognizes a first change pattern for the amount of change of the minimum Y value and a second change pattern for the amount of change of the maximum Y value among the coordinate values ​​for the cooking area (PL), and then recognizes the shape of the container as a circular shape based on the fact that the first change pattern is recognized as a parabolic pattern that rises after the amount of change of the minimum Y value decreases, and the second change pattern is recognized as a parabolic pattern that decreases after the amount of change of the maximum Y value increases.

[0285] Here, the circular shape may include a circular shape with the same diameter and an elliptical shape with different diameters. That is, the control unit (160) can recognize whether the shape of the container is circular or elliptical based on the change amount of the minimum Y value and the change amount of the maximum Y value.

[0286] The control unit (160) can recognize a third change pattern for the amount of change of the minimum X value for each Y value and a fourth change pattern for the amount of change of the maximum X value for each Y value, and then recognize the shape of the container as the original shape based on the third and fourth change patterns.

[0287] The control unit (160) recognizes a first length corresponding to the difference between a minimum X value (Xa) and a maximum X value (Xc) and a second length corresponding to the difference between a minimum Y value (Ya) and a maximum Y value (Yc) when the shape of the container is a circular shape, and can recognize the size of the container based on at least one of the first and second lengths.

[0288] Recognizing the shape and size of a container based on the maximum X value, minimum X value, maximum Y value, and minimum Y value is merely one example of recognizing the shape and size of a container, and the configuration for recognizing the shape and size of a container is not limited to this.

[0289] When container identification sensors, such as optical sensors or capacitive sensors, are installed, multiple container identification sensors may be installed inside the main body and may correspond to each of multiple coils, and may have X and Y values ​​based on the order of installation inside the main body.

[0290] For example, the first container identification sensor positioned closest to the origin coordinates (X0, Y0) of the top plate may have coordinate values ​​(X1, Y1), the second container identification sensor positioned closest in the X-axis direction may have coordinate values ​​(X2, Y1), the third container identification sensor positioned closest to the first container identification sensor in the Y-axis direction may have coordinate values ​​(X1, Y2), and the p-th container identification sensor positioned closest to the endpoint coordinates (Xn, Ym) may have coordinate values ​​(Xn, Ym).

[0291] Here, p in the p-container identification sensor can be a number corresponding to n×m.

[0292] The number of container identification sensors can be equal to the number of coils.

[0293] The control unit (160) recognizes the coordinate information of a container identification sensor that detects a container among a plurality of container identification sensors, and can recognize the shape of the container and the size of the container based on the coordinate information of the recognized container identification sensor.

[0294] A configuration for recognizing the shape and size of a container based on detection information detected by a container identification sensor (140), such as a light sensor or a capacitance sensor, may be the same as a configuration for recognizing the shape and size of a container using a current sensor, so a description thereof is omitted.

[0295] The control unit (160) can control the power level of the coil to a reference power level, recognize the efficiency of the container based on current information detected by a current sensor connected to the coil, and store information about the recognized efficiency of the container as identification information of the container.

[0296] The control unit (160) can recognize the efficiency of the container related to the heating performance of the container based on the difference between the coil current and the target current based on current information detected by the current sensor. For example, the control unit (160) can recognize the efficiency of the container based on the ratio (%) of the coil current to the target current. The efficiency of the container can correspond to the thermal conductivity of the container and the electrical conductivity of the container.

[0297] The target current may be equal to or greater than the reference current used to detect the presence or absence of the container.

[0298] The control unit (160) may receive identification information of a container from a server or a user device and store the received identification information of the container. In this case, the control unit (160) may transmit to the server the request information for the model information of the container and the identification information of the container received from the user interface of the cooking device or the user device.

[0299] The control unit (160) may receive image information from an image sensor provided in a cooking device or an image sensor provided in an external device, process the received image information, and then recognize identification information of the container based on the processed image information.

[0300] The control unit (160) can store identification information of the recognized container and information about the cooking area of ​​the container by matching them.

[0301] Information regarding the cooking area of ​​the container may include location information of the container. The location information of the container may include coordinate information of the container.

[0302] When the control unit (160) stores the location information of the container, it is possible to store the coordinate information of the center point of the container among the coordinate information of the container as representative location information, and it is also possible to store the minimum X value and minimum Y value among the coordinate information of the container as representative location information, and it is also possible to store the maximum X value and maximum Y value among the coordinate information of the container as representative location information.

[0303] Container Number Container Shape Container Size Container Efficiency Container Representative Location 1 Square A*B 70%(Xa, Ya) 2 Circle R=c 80%(Xa, Yb)

[0304] The control unit (160) may also learn information about the cooking area of ​​the container, including the X values ​​of the recognized X coordinate and the Y values ​​of the Y coordinate. Learning the cooking area of ​​the container for each container may include learning the cooking area of ​​the container preferred by the user for each container.

[0305] For example, if the error between the representative position of the first recognized container and the representative position of the nth recognized container is within a reference error range, the control unit (160) can recognize a cooking area based on the position of the first recognized container and learn the recognized cooking area as the cooking area of ​​the container preferred by the user.

[0306] As another example, if the error between the representative position of the first recognized container and the representative position of the nth recognized container is within a reference error range, the control unit (160) may obtain an average position between the representative position of the first recognized container and the nth representative position, recognize a cooking area based on the obtained average position, and learn the recognized cooking area as the cooking area of ​​the container preferred by the user. In this case, the control unit (160) may also obtain an average position based on n positions that are within the reference error range.

[0307] Examples of recognizing the cooking area of ​​the container, the shape information of the container, and the size information of the container by the control unit are not limited to the examples described above.

[0308] In this embodiment, the configuration for recognizing the cooking area of ​​the container, the shape information of the container, and the size information of the container based on the detection information of a plurality of container identification sensors (140) has been described separately. However, the control unit (160) of this embodiment can identify the container identification sensor (140) that detects the placement of the container among the plurality of container identification sensors (140), and can recognize the cooking area of ​​the container, the shape information of the container, and the size information of the container based on the location information of the identified container identification sensor (140).

[0309] The control unit (160) can recognize efficiency information of the container based on detection information of at least one container identification sensor (140) that detects the placement of the container among a plurality of container identification sensors (140).

[0310] The control unit (160) learns cooking history information based on the identification information of the container and the cooking area of ​​the container, and can recognize the user's cooking pattern based on the cooking history information for each container.

[0311] The user's cooking patterns can be changed by learning cooking history information.

[0312] Recognizing the user's cooking patterns may include recognizing the cooking area preferred by the user for each container.

[0313] The cooking area of ​​the container preferred by the user may be an area where the container is placed at a frequency greater than the standard frequency.

[0314] The cooking area of ​​the container preferred by the user may be an area where the number of times the container is placed is greater than or equal to a standard number of times. This will be explained with reference to FIGS. 10 and 11.

[0315] As shown in FIG. 10, if the container is a rectangular container with a long handle, the user may place the container (200) on the left side of the lower part of the cooking device or on the right side of the lower part of the cooking device depending on which hand is used more frequently, the left or the right.

[0316] As shown in FIG. 11, if the container is a circular container with a short handle, the user can frequently place the container (200) in the center of the lower part of the cooking device.

[0317] As such, the cooking area of ​​a container preferred by the user can be determined based on the characteristics of the container or the user. Taking this into consideration, the cooking device can learn the container-specific cooking area corresponding to the characteristics of the container or the user.

[0318] The control unit (160) obtains the number of times each container is used and can recognize the user's preference for the container based on the obtained number of times each container is used.

[0319] The control unit (160) may determine the priority of the containers based on the number of times each container is used and store the determined priority of the containers. For example, the control unit (160) may assign a higher priority as the number of times a container is used increases.

[0320] The control unit (160) can recognize the cooking start time and cooking end time when cooking food in the container, and can store cooking time information regarding the recognized cooking start time and cooking end time.

[0321] The control unit (160) can acquire identification information of the container and the cooking area of ​​the container by cooking time, and learn cooking history information by cooking time based on the acquired identification information of the container and the cooking area of ​​the container by cooking time.

[0322] The control unit (160) obtains the number of times each container is used for each cooking time, determines the priority of the containers for each cooking time based on the obtained number of times each container is used for each cooking time, and can also store the determined priority of the containers for each cooking time.

[0323] The control unit (160) can obtain the number of times a container is recognized by each container identification sensor, and it is also possible to recognize the user's preference for a cooking area based on the number of times a container is recognized by each container identification sensor obtained.

[0324] The control unit (160) can determine the priority of cooking areas based on the number of times a container is recognized by each container identification sensor and can also store the determined priority of cooking areas.

[0325] One or more coils may be provided in a single cooking area. The two or more coils forming a single cooking area may be coils placed adjacent to each other.

[0326] One or more container identification sensors may be provided in a single cooking area. The two or more container identification sensors provided in a single cooking area may be container identification sensors placed adjacent to each other.

[0327] The control unit (160) can count the number of cooking times per cooking area each time food is cooked, determine the priority of the cooking areas based on the counted number of cooking times per cooking area, and store the determined priority of the cooking areas.

[0328] The control unit (160) can acquire operation information of the cooking area for each container and acquire cooking history information based on the acquired operation information of the cooking area for each container and identification information of the container.

[0329] The operation information of the cooking area may include information regarding the power level and operation time of the cooking area. The operation information of the cooking area may include information regarding changes in the power level of the cooking area and time per power level.

[0330] The control unit (160) can learn cooking history information based on operation information per cooking area and cooking time information per cooking area, in addition to identification information of the container and cooking area of ​​the container.

[0331] The control unit (160) can control the second output interface (123) to recognize identification information of a container based on detection information detected by the container identification sensor (140), identify a recommended cooking area based on the recognized identification information of the container and cooking history information, and output guidance information for the identified recommended cooking area.

[0332] For example, the control unit (160) can recognize the size information of the container based on the detection information detected by the container identification sensor (140) and identify a recommended cooking area corresponding to the recognized size information of the container among the cooking history information.

[0333] As another example, the control unit (160) can recognize the shape information and size information of the container based on the detection information detected by the container identification sensor (140) and identify a recommended cooking area corresponding to the recognized shape information and size information of the container among the cooking history information.

[0334] As another example, the control unit (160) can recognize the efficiency information and size information of the container based on the detection information detected by the container identification sensor (140) and identify a recommended cooking area corresponding to the recognized efficiency information and size information of the container among the cooking history information.

[0335] The control unit (160) may also transmit guidance information regarding the identified recommended cooking area to a user device or home appliance.

[0336] As illustrated in FIG. 12, the control unit (160) recognizes the identification information of the container and the current cooking area of ​​the container based on the detection information detected by the container identification sensor (140), and recognizes the learned cooking area based on the cooking history information. If the current cooking area of ​​the container and the learned cooking area are different, the control unit (160) can control the second output interface (123) to display the learned cooking area among the areas of the second output interface (123) as the recommended cooking area (GL).

[0337] The control unit (160) can recognize representative location information of the container based on detection information received from the container identification sensor, and can also recognize a cooking area based on the recognized representative location information, size information of the container, and shape information of the container.

[0338] The control unit (160) may also control the second output interface (123) to display the current cooking area as the recommended cooking area if the error between the current cooking area of ​​the container and the learned cooking area is within the reference error range.

[0339] The control unit (160) can control the second output interface (123) to display the learned cooking area among the areas of the second output interface (123) as the recommended cooking area (GL) when the error between the current cooking area of ​​the container and the learned cooking area deviates from the reference error range.

[0340] The control unit (160) can obtain an error by comparing the current representative position for the current cooking area and the learned representative position for the learned cooking area when comparing the current cooking area and the learned cooking area of ​​the container.

[0341] The control unit (160) can identify a recommended cooking area based on at least one of the following: cooking time information, cooking status information of food, recipe information, movement information of the container being cooked, and number of containers, in addition to the identification information of the container and cooking history information, and can control the second output interface (123) to display the identified recommended cooking area. This will be explained with reference to FIGS. 13 to 26.

[0342] The control unit (160) can identify that there is a possibility of the food contained in the container overflowing when it receives a selection signal for the cooking area and a selection signal for the possibility of the food overflowing from the input interface (121), and can identify whether there is a possibility of the food contained in the container overflowing during cooking based on image information received from the image sensor.

[0343] The image sensor may be an image sensor provided in an external device or an image sensor provided in a cooking device.

[0344] If the control unit (160) identifies that there is a possibility of food overflow before the start of cooking, it can identify a recommended cooking area based on safety area, container identification information, and cooking history information, and control the second output interface (123) to display the identified recommended cooking area.

[0345] The safety zone may be an area (FZ) of the first area of ​​the top plate (110) that is far from the user interface (120). The safety zone may be a preset area.

[0346] The safety area may include an area of ​​the first area of ​​the top plate (110) where the user's usage frequency is less than the reference frequency.

[0347] As illustrated in FIG. 13, when the container (200) has a square shape and the learned cooking area is the left side of the bottom of the top plate, the control unit (160) can identify the left side of the safe area as the recommended cooking area (RZ) based on the identification that there is a possibility of food overflow in the container, and control the second output interface (123) to display the identified recommended cooking area.

[0348] The control unit (160) can also identify the possibility of food overflow based on vibration information detected by a vibration sensor (not shown) provided in the cooking device during the cooking of food.

[0349] The control unit (160) can monitor the cooking status of the food based on image information received from an image sensor during cooking of the food, and can also identify the possibility of the food overflowing based on the monitoring status.

[0350] The control unit (160) can control the first output interface (122) to identify whether the cooking area of ​​the container is a safe area when it is identified that there is a possibility of food overflow during cooking, and to output guidance information suggesting the movement of the container based on the fact that the cooking area of ​​the container is not identified as a safe area.

[0351] When controlling the output of guidance information for a container movement suggestion, the control unit (160) can control the second output interface (123) to identify a recommended cooking area within the safe area based on the safe area, container identification information, and cooking history information, and to display the identified recommended cooking area.

[0352] As illustrated in FIG. 14a, when the mounting of the container (200) is recognized, the control unit (160) can identify a recommended cooking area (RZ1) within the intervention area (NZ) based on the intervention area, the identification information of the container, and the cooking history information, and control the second output interface (123) to display the identified recommended cooking area (RZ1).

[0353] The intervention area is a region where user intervention in food preparation is easy and frequent, and it may be a region (NRNZ) where the usage frequency exceeds the reference usage frequency. The intervention area may be a region set by learning.

[0354] The intervention area may include an area close to the user interface (NRNZ).

[0355] When the control unit (160) recognizes the placement of the container (200), it is possible to identify the area with the highest usage frequency by the user and identify the identified area as a recommended cooking area.

[0356] Information regarding the area with the highest usage frequency by the user may be information acquired and stored through learning.

[0357] As illustrated in FIG. 14b, the control unit (160) identifies whether the current cooking area of ​​the container is a safe area when it is identified that there is a possibility of food overflow during cooking, and if the current cooking area is not identified as a safe area, it identifies a recommended cooking area (RZ2) based on the safe area, the identification information of the container and the cooking history information, and can control the second output interface (123) to display the identified recommended cooking area (RZ2).

[0358] The control unit (160) can monitor the cooking status of the food during cooking, identify the end of the food overflow based on the monitored cooking status of the food, and when the end of the food overflow is identified, identify a recommended cooking area based on the intervention area, container identification information and cooking history information, and control the second output interface (123) to display the identified recommended cooking area.

[0359] The control unit (160) can also lower the power level of the cooking area when it is identified that the food has started to overflow during cooking.

[0360] When the control unit (160) identifies a recommended cooking area, it identifies a cooking-unavailable area among the first areas of the top plate (110) and can identify a recommended cooking area in the cooking-available area excluding the cooking-unavailable area.

[0361] An area that cannot be cooked may be an area that is already being cooked by another container.

[0362] As illustrated in FIG. 15, the control unit (160) can identify the recommended cooking area of ​​the first container (201), recognize it as an intervention area, recognize whether the second container (202) is placed within the intervention area, and if it is recognized that the second container (202) is placed within the intervention area, identify the other cooking area where the second container (202) is placed as an area where cooking is not possible, identify the recommended cooking area (RZ3) based on the area excluding the identified area where cooking is not possible among the intervention areas (NZ), and control the second output interface (123) to display the identified recommended cooking area.

[0363] If the control unit (160) identifies that there is no cooking area in the intervention area, it is also possible to identify a recommended cooking area in an area adjacent to the intervention area.

[0364] The area adjacent to the intervention area may be the area between the safety area and the intervention area.

[0365] The control unit (160) recognizes whether multiple containers are mounted based on detection information detected by the container identification sensor (140), and when it is recognized that multiple containers are mounted on the top plate of the cooking device, recognizes the identification information of the containers based on the detection information detected by the container identification sensor (140), recognizes the priority of each container based on the recognized identification information of the containers, identifies the cooking area with a high priority starting from the container with a high priority as a recommended cooking area based on the recognized priority of each container and the learned priority of each cooking area, and controls the second output interface (123) to display the recommended cooking area for each container.

[0366] The control unit (160) can determine the priority of each container in order of largest size based on the identification information of a plurality of containers, identify the cooking area with the highest priority starting from the container with the highest priority as the recommended cooking area based on the determined priority of each container and the learned priority of each cooking area, and control the second output interface (123) to display the recommended cooking area for each container.

[0367] As illustrated in FIG. 16, a first container (201) having a first size and a second container (202) having a second size smaller than the first size are mounted, and when the priority of the cooking area on the right side of the bottom of the top plate is 1st and the priority of the cooking area on the left side of the bottom of the top plate is 2nd, the control unit (160) identifies the cooking area with the 1st priority as the recommended cooking area (RZ1) of the first container (201) and identifies the cooking area with the 2nd priority as the recommended cooking area (RZ2) of the second container (202), and determines the size and shape of each recommended cooking area based on the size information and shape information of the first and second containers, and controls the second output interface (123) to display the recommended cooking area based on the determined size and shape of each recommended cooking area.

[0368] When image information regarding an image of a cooking device is received from an image sensor while multiple containers are mounted on a cooking device, the control unit (160) can recognize whether there is a container with a possibility of food overflow based on the received image information.

[0369] The control unit (160) controls the first output interface to display position information of the multiple containers while the multiple containers are mounted on the cooking device, and it is also possible to receive a selection signal for a container that has a possibility of overflowing food through the input interface (121).

[0370] As illustrated in FIG. 17, when the first and second containers are mounted on the cooking device and there is a possibility of the food in the first container overflowing, the control unit (160) can identify a recommended cooking area (RZ1) of the first container (201) within a safe area based on the identification information and cooking history information of the first container (201), and identify a recommended cooking area of ​​the second container within an intervention area based on the identification information and cooking history information of the second container (202).

[0371] The control unit (160) periodically recognizes the identification information of the container and the cooking area of ​​the container while cooking food, identifies whether the cooking area has changed based on the identification information of the container and the cooking area of ​​the container, and recognizes the movement of the container based on the change in the cooking area. The identification information of the container may include at least one of the size of the container, the shape of the container, and the efficiency of the container.

[0372] The control unit (160) can recognize whether the container is moving based on image information received from the image sensor.

[0373] The control unit (160) can recognize the movement of the container based on the temperature information of the cooking area detected by a plurality of temperature sensors (not shown) being detected in another cooking area.

[0374] The control unit (160) recognizes the cooking time of the food and whether the container is moved while the food is being cooked in the container, recognizes the second cooking area of ​​the moved container based on the fact that the container is moved to a different location from the first cooking area, recognizes the power level and operating time in the first cooking area and the power level and operating time in the moved second cooking area, respectively, and acquires cooking history information for the first container based on the recognized power level and operating time in the first cooking area and the power level and operating time in the second cooking area, and it is also possible to store the acquired cooking history information.

[0375] The cooking time may include the time of movement when the container was moved.

[0376] The control unit (160) can recognize whether another container is placed in the first cooking area based on detection information detected by the container identification sensor (140), and if it is recognized that another container is placed in the first cooking area, it can also store the identification information of the other container and the power level and operating time of the first cooking area as cooking history information.

[0377] The control unit (160) can recognize whether another container is placed in the first cooking area before reaching a preset time from the time the container is moved, based on detection information detected by the container identification sensor (140).

[0378] The control unit (160) can learn cooking history information for the first container based on the identification information of the first container, the movement information of the first container, the cooking time, and the second cooking area.

[0379] The control unit (160) checks the current time and recognizes the identification information of the container when the container is placed, and can control the second output interface (123) to identify the recommended cooking area of ​​the container and display the identified recommended cooking area of ​​the container based on the confirmed current time, the identification information of the container, and the cooking history information. This will be explained with reference to FIGS. 18a, 18b, and 19.

[0380] As illustrated in FIGS. 18a and 18b, the control unit (160) can acquire cooking history information by starting to cook food in the first container at 7:00 AM for at least 5 days, moving the first container (201) to a second cooking area adjacent to the first cooking area at 7:20 AM, and then placing the second container in the first cooking area, and can learn the user's cooking pattern based on the acquired cooking history information.

[0381] When the first container is moved, the control unit (160) recognizes whether the first container has moved to a second cooking area that includes a part of the first cooking area based on the position information of the first container, and if it is recognized that the first container has moved to a second cooking area that includes a part of the first cooking area, it can recognize that the first container has moved to a second cooking area adjacent to the first cooking area.

[0382] As illustrated in FIG. 19, the control unit (160) learns the user's cooking pattern, and when the placement of the first container is recognized at 7:00 AM, it identifies a recommended cooking area of ​​the first container based on the identification information of the first container and the cooking time, and can control the second output interface (123) to display the recommended cooking area (RZ1) of the identified container.

[0383] By doing so, the area where the second container can be placed (i.e., the first cooking area) can be secured in advance at 7:20, thereby preventing the inconvenience of the user having to move the first container to another location while cooking food.

[0384] The control unit (160) controls the power level and operating time of the second cooking area based on the identification information and cooking history information of the first container, and when the second container is placed in the first cooking area, it is also possible to control the power level and operating time of the first cooking area based on the identification information and cooking history information of the second container.

[0385] The control unit (160) recognizes whether the first container is moved while cooking food in the first container, and if the first container is moved to another location that is not adjacent to the first cooking area, it recognizes the second cooking area of ​​the moved first container and can learn cooking history information for the first container based on the first cooking area and the second cooking area.

[0386] As illustrated in FIG. 20a and FIG. 20b, the control unit (160) recognizes whether the first container (201) is moved while cooking food in the first container (201), and if the first container (201) is moved to a different location from the first cooking area, recognizes the second cooking area of ​​the moved first container (201), and if the placement of the second container (202) is recognized, recognizes the identification information of the second container (202) and the cooking area of ​​the second container based on the detection information detected by the container identification sensor (140), and can learn cooking history information for the first and second containers (201, 202) based on the recognized first and second cooking areas of the first container (201) and the recognized cooking area of ​​the second container (201).

[0387] As illustrated in FIG. 21, the control unit (160) can control the second output interface (123) to identify a recommended cooking area of ​​the first container based on the identification information and cooking history information of the first container and to display the identified recommended cooking area (RZ1) of the first container (201) when the movement of the first container (201) is recognized and the placement of the second container is recognized during the cooking of food in the first container (201).

[0388] As illustrated in FIG. 22, the control unit (160) can control the second output interface (123) to identify a recommended cooking area of ​​the second container based on the identification information and cooking history information of the second container and to display the recommended cooking area (RZ2) of the identified second container (202) when the movement of the first container (201) is recognized and the placement of the second container is recognized during the cooking of food in the first container (201).

[0389] Here, the second container may be a container newly installed in the cooking device, or a container that was performing cooking in the third cooking area of ​​the cooking device.

[0390] The control unit (160) can control the second output interface (123) to identify a recommended cooking area based on container identification information, cooking history information, and recipe information, and to output guidance information for the identified recommended cooking area, if the cooking mode of the food is recipe mode. This will be explained with reference to FIGS. 23 to 26.

[0391] Recipe information may include information on the recipe name, the number of notifications related to food preparation, cooking time, power level, and operating time per power level, and may further include information on the possibility of food overflowing during cooking.

[0392] The control unit (160) can identify a recommended cooking area based on at least one of a recipe name, the number of notifications related to cooking food, the cooking time, and the power level.

[0393] The control unit (160) can also recognize whether there is a possibility of food overflowing during cooking based on recipe information.

[0394] As illustrated in FIG. 23, the control unit (160) can recognize whether there is a possibility of food overflow during cooking based on recipe information, and if it is recognized that there is a possibility of food overflow, it can identify a recommended cooking area based on container identification information, cooking history information and safety area, and control the second output interface (123) to display the identified recommended cooking area (RZ1).

[0395] As illustrated in FIG. 24, the control unit (160) identifies whether user intervention is required during automatic cooking of food based on recipe information, and if user intervention is identified, identifies a recommended cooking area (RZ1) based on container identification information, cooking history information and intervention area, and can control the second output interface (123) to display the identified recommended cooking area (RZ1).

[0396] When the control unit (160) identifies that user intervention is unnecessary when cooking food in recipe mode, it can identify a recommended cooking area (RZ1) in the safe area.

[0397] The control unit (160) can also identify a recommended cooking area based on the number of times the user intervenes and the priority of each cooking area when cooking food in recipe mode.

[0398] For example, the control unit (160) can identify a cooking area with a high priority as a recommended cooking area if the number of user interventions is greater than or equal to the standard number of interventions, and identify a cooking area with a low priority as a recommended cooking area if the number of user interventions is less than the standard number of interventions.

[0399] The high-priority cooking area and the low-priority cooking area may be areas acquired through learning.

[0400] A high-priority cooking area may be a cooking area where the user's usage frequency exceeds a reference frequency. A high-priority cooking area may be an area close to the user interface.

[0401] A low-priority cooking area may be a cooking area where the user's usage frequency is below the standard frequency. A low-priority cooking area may be an area far from the user interface.

[0402] As illustrated in FIG. 25, when a first container (201) for cooking food in recipe mode and a second container (202) for cooking food manually are mounted on a cooking device, the control unit (160) recognizes whether there is a possibility of the food in the first container (201) overflowing based on recipe information, and if there is a possibility of the food in the first container (201) overflowing, it identifies the first container (201) as a recommended cooking area based on the identification information, cooking history information, and safety area of ​​the first container (201), and identifies the second container (202) as a recommended cooking area based on the identification information, cooking history information, and intervention area of ​​the second container (202).

[0403] As illustrated in FIG. 26, when the control unit (160) recognizes that the food in the first container (201) has finished overflowing during cooking in recipe mode, it identifies the first container (201) as a recommended cooking area based on the identification information, cooking history information, and intervention area of ​​the first container (201), and controls the second output interface (123) to display the identified recommended cooking area (RZ1).

[0404] The control unit (160) identifies whether the cooking area is changed due to the movement of the first container based on detection information detected by the container identification sensor, and if it is identified that the cooking area of ​​the first container has changed, it can continuously control the automatic cooking of food by controlling the power level and operating time of the moved cooking area based on recipe information.

[0405] If the control unit (160) recognizes that there is no possibility of the food in the first container overflowing based on recipe information and that user intervention is unnecessary, it can identify the first container as a recommended cooking area based on the first container's identification information, cooking history information, and safety area, and identify the second container as a recommended cooking area based on the second container's identification information, cooking history information, and intervention area.

[0406] The control unit (160) recognizes the priority of the first container and the second container based on recipe information, and if it recognizes that there is no possibility of the food in the first container overflowing and user intervention is required, it can identify the recommended cooking area for the first container and the second container based on the priority of the first and second containers and the priority of the cooking areas.

[0407] If the control unit (160) recognizes that there is no possibility of the food in the first container overflowing based on recipe information and that user intervention is required, it is also possible to identify recommended cooking areas for the first container and the second container based on identification information of the first container, identification information of the second container, and cooking history information.

[0408] The control unit (160) can identify the possibility of food overflow and whether user intervention is required based on the course of food received through the input interface (121), and can also identify a recommended cooking area of ​​the container based on the identified possibility of food overflow, whether user intervention is required, container identification information, and cooking history information.

[0409] The control unit (160) can control the first output interface (122) to output guidance information for user intervention when it recognizes that user intervention is required.

[0410] When the control unit (160) identifies a recommended cooking area of ​​a container, it can identify the recommended cooking area of ​​the container based on the container identification information in the remaining area excluding the cooking area where another container is mounted. Here, the container identification information used when identifying the recommended cooking area may include container size information and container shape information.

[0411] The control unit (160) may also control the first output interface to output information regarding the recommended cooking area of ​​the container through the first output interface. Although this configuration corresponds to the configuration of other embodiments, it can also be implemented through this embodiment.

[0412] The control unit (160) can control the first output interface (122) to output guidance information suggesting the execution of a display mode for a recommended cooking area when the learning of the cooking area of ​​the container for each container is completed.

[0413] The control unit (160) may also transmit guidance information suggesting the performance of a display mode for a recommended cooking area to a user device or home appliance. In this case, the user device or home appliance may display guidance information suggesting the performance of a display mode for a recommended cooking area.

[0414] When the control unit (160) receives an approval command for the performance of the recommended cooking area display mode through the input interface (121), it can perform the recommended cooking area display mode.

[0415] The control unit (160) can control the second output interface to display the identified recommended cooking area based on the performance of the recommended cooking area display mode.

[0416] When a rejection command for a suggestion to display a recommended cooking area is received through the input interface (121), the control unit (160) can control the second output interface to identify a cooking area based on the priority of preset cooking areas and display the identified cooking area. Here, the priority of the preset cooking areas may be information stored during the manufacture of the cooking device.

[0417] The control unit (160) may include at least one processor (161) for controlling the operation of the cooking device (1) and at least one memory (162) for storing a program and data for controlling the operation of the cooking device (1).

[0418] At least one processor (161) may include an algorithm for controlling the operation of components within the cooking device (1), at least one memory for storing data in the form of a program, and one or more processor chips that perform the aforementioned operation using the data stored in at least one memory, or one or more processing cores.

[0419] At least one processor (161) can process various data and various signals using instructions, data, programs and / or software stored in memory.

[0420] At least one processor (161) may include one or more of a CPU (Central Processing Unit), GPU (Graphics Processing Unit), APU (Accelerated Processing Unit), MIC (Many Integrated Core), DSP (Digital Signal Processor), NPU (Neural Processing Unit), hardware accelerator, or machine learning accelerator.

[0421] The memory (162) can store cooking history information and can store identification information of each container.

[0422] The memory (162) can store information about the priority of the containers and the priority of the cooking areas.

[0423] The memory (162) can also store information about the priority of containers by cooking time.

[0424] The memory (162) can also store information about the number of times a container is recognized by each container identification sensor.

[0425] Memory (162) can store recipe information.

[0426] The memory (162) can store identification information and location information for each of the plurality of coils. The location information for each of the plurality of coils may include coordinate information.

[0427] The memory (162) can store coordinate information of the second output interface of the user interface that is matched to the position information of each of the multiple coils.

[0428] The memory (162) can store identification information of a current sensor that matches the identification information of each of the multiple coils.

[0429] The memory (162) can store information about a reference current for recognizing whether or not there is a container.

[0430] The memory (162) can store location information of multiple container identification sensors.

[0431] The location information of multiple container identification sensors may include coordinate information.

[0432] The memory (162) can store data necessary for various embodiments.

[0433] The memory (162) may be implemented in the form of a memory embedded in the cooking device (1) or in the form of a memory that can be attached to and detached from the cooking device (1), depending on the purpose of data storage. For example, data for operating the cooking device (1) may be stored in a memory embedded in the cooking device (1), and data for the expansion function of the cooking device (1) may be stored in a memory that can be attached to and detached from the cooking device (1).

[0434] Meanwhile, the memory embedded in the cooking device (1) may be implemented as at least one of volatile memory (e.g., DRAM (dynamic RAM), SRAM (static RAM), or SDRAM (synchronous dynamic RAM), non-volatile memory (e.g., OTPROM (one time programmable ROM), PROM (programmable ROM), EPROM (erasable and programmable ROM), EEPROM (electrically erasable and programmable ROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash), hard drive, or solid state drive (SSD).

[0436] The memory (162) may include one or more memory chips or one or more memory blocks.

[0437] Functions related to artificial intelligence according to the present disclosure may be operated through a processor and memory. The processor may be composed of one or more processors. In this case, the one or more processors may be general-purpose processors such as CPUs, APs, and DSPs (Digital Signal Processors), graphics-dedicated processors such as GPUs and VPUs (Vision Processing Units), or artificial intelligence-dedicated processors such as NPUs. The one or more processors control the processing of input data according to predefined operation rules or artificial intelligence models stored in memory. Alternatively, if the one or more processors are artificial intelligence-dedicated processors, the artificial intelligence-dedicated processors may be designed with a hardware structure specialized for processing a specific artificial intelligence model.

[0438] The predefined rules of operation or artificial intelligence models are characterized by being created through learning. Here, being created through learning means that a basic artificial intelligence model is trained using a number of training data by a learning algorithm, thereby creating predefined rules of operation or artificial intelligence models configured to perform desired characteristics (or objectives). Such learning may be performed on the device itself where the artificial intelligence according to the present disclosure is executed, or it may be performed through a separate server and / or system. Examples of learning algorithms include supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but are not limited to the examples described above.

[0439] An artificial intelligence model may be composed of multiple neural network layers. Each of the multiple neural network layers has multiple weight values ​​and performs neural network operations through operations between the results of previous layers and the multiple weights. The multiple weights possessed by the multiple neural network layers can be optimized based on the learning results of the artificial intelligence model. For example, the multiple weights may be updated so that the loss value or cost value obtained from the artificial intelligence model during the learning process is reduced or minimized. Artificial neural networks may include deep neural networks (DNNs), such as Convolutional Neural Networks (CNNs), Deep Neural Networks (DNNs), Recurrent Neural Networks (RNNs), Restricted Boltzmann Machines (RBMs), Deep Belief Networks (DBNs), Bidirectional Recurrent Deep Neural Networks (BRDNNs), or Deep Q-Networks, but are not limited to the examples mentioned above.

[0440] At least one component may be added or removed in response to the performance of the components of the cooking device (1) illustrated in FIG. 5. Additionally, it will be readily understood by those skilled in the art that the relative positions of the components may be changed in response to the performance or structure of the cooking device.

[0441] Meanwhile, each component illustrated in Fig. 5 refers to a software and / or hardware component such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0442] FIG. 27 is a control flowchart of a cooking device according to one embodiment.

[0443] The cooking device identifies whether the first container is mounted based on detection information detected by the container identification sensor (140), and if it is identified that the first container is mounted, it recognizes the identification information of the first container based on the detection information detected by the container identification sensor (140) and stores the recognized identification information of the first container.

[0444] The container identification sensor (140) may include at least one of a plurality of current sensors, capacitance sensors, image sensors, and light sensors, but the container identification sensor is not limited thereto.

[0445] Recognizing identification information of the first container may include recognizing at least one of size information of the first container, shape information of the first container, and efficiency information of the first container.

[0446] Recognizing identification information of the first container may include recognizing coordinate information of an area on which the first container is mounted and recognizing size information and shape information of the first container based on the recognized coordinate information (see FIGS. 8 and 9).

[0447] Recognizing identification information of the first container may include recognizing efficiency information of the container based on the current flowing through the coil placed in the area where the first container is mounted and the target current.

[0448] When the cooking device receives the power level of the cooking area where the first container is mounted through the input interface (121), it recognizes that the cooking area of ​​the first container has been determined, controls the power level of the cooking area of ​​the first container, and stores the location information of the recognized cooking area of ​​the first container by matching it with the identification information of the first container, and can store it as cooking history information.

[0449] The cooking device recognizes container-specific identification information for the second container, the third container, and the nth container, and recognizes location information for the cooking area of ​​each container (301), and can store the container-specific identification information and the location information for the cooking area of ​​each container as cooking history information.

[0450] The location information for the cooking area of ​​each container may include multiple coordinate information. The cooking device may store any one of the multiple coordinate information of each container as representative location information for the cooking area of ​​each container.

[0451] The cooking device learns cooking history information to learn the cooking area of ​​each container and learns it more than a standard number of times for each container (302). When it learns more than a standard number of times for each container, it can obtain a recommended cooking area for each container based on the learned information (303). This will be explained in more detail.

[0452] Whenever the cooking device identifies that the first container is mounted on the top plate based on detection information detected by the container identification sensor (140), it identifies whether the identification information of the first container is included in the cooking history information, and if the identification information of the first container is included in the cooking history information, it recognizes the current location information for the current cooking area and recognizes the stored location information for the stored cooking area, and can obtain a recommended cooking area for the first container based on the current location information and the stored location information of the first container.

[0453] For example, the cooking device recognizes first representative location information for the current cooking area and second representative location information for the stored cooking area, and if the error between the first representative location information and the second representative location information is within a reference error range, it can obtain a recommended cooking area of ​​the first container based on the second representative location information.

[0454] As another example, if the error between the first representative position information and the second representative position information is within a reference error range, the cooking device can obtain the average position information of the first representative position information and the second representative position information, and obtain the recommended cooking area of ​​the first container based on the obtained average position information.

[0455] If the error between the first representative position information and the second representative position information exceeds the reference error range, the cooking device can store the first representative position information and the second representative position information as information regarding the cooking area of ​​the first container.

[0456] Afterwards, whenever the cooking device identifies that the first container is mounted on the top plate, it recognizes the current representative location information of the first container, checks the stored representative location information among the stored first representative location information and the stored second representative location information that is within the reference error range of the current representative location information, and can obtain a recommended cooking area of ​​the first container based on the confirmed representative location information and the current representative location information.

[0457] The cooking device recognizes the number of times a recommended cooking area for a first container is acquired, and if the recognized number of acquisitions is greater than or equal to a reference number, the acquired recommended cooking area can be acquired as a cooking area by learning.

[0458] The cooking device can store recommended cooking areas that have acquired more than a standard number of times per container as cooking areas based on container-specific learning.

[0459] The cooking device can acquire cooking history information for each container through learning and recognize the user's cooking patterns based on the cooking history information for each container.

[0460] Recognizing the user's cooking pattern may include recognizing the cooking area preferred by the user for each container. The cooking area of ​​the container preferred by the user may be an area where the frequency of placing the container is greater than or equal to a reference frequency. The cooking area of ​​the container preferred by the user may be an area where the number of times the container is placed is greater than or equal to a reference number of times.

[0461] When the cooking device completes learning of the cooking area of ​​each container, it outputs guidance information suggesting the performance of the display mode of the recommended cooking area through the first output interface (122) (304).

[0462] The cooking device may also transmit guidance information suggesting the execution of the recommended cooking area display mode to a user device or home appliance. In this case, the user device or home appliance may display guidance information suggesting the execution of the recommended cooking area display mode.

[0463] When the cooking device receives an approval command for the performance of the recommended cooking area display mode through the input interface (121) (305), it performs the recommended cooking area display mode (306).

[0464] The cooking device identifies whether a container is mounted based on the performance of the display mode of the recommended cooking area (307), and if it is identified that the container is mounted, it identifies a recommended cooking area based on the container's identification information and cooking history information (308) and can display the identified recommended cooking area through the second output interface (309).

[0465] More specifically, when the first container is placed, the cooking device recognizes the identification information of the first container based on the detection information detected by the container identification sensor (140), identifies the recommended cooking area of ​​the first container based on the recognized identification information of the first container and the cooking history information, and can display the identified recommended cooking area through the second output interface.

[0466] Identifying a recommended cooking area of ​​a first container may include identifying a recommended cooking area corresponding to the identification information of the first container in the cooking history information.

[0467] The cooking device can display the border of the recommended cooking area at a position corresponding to the border of the recommended cooking area within the area of ​​the second output interface.

[0468] The cooking device may also receive an approval command for the performance of the display mode of the recommended cooking area received from the user device or home appliance via the communication interface (170).

[0469] The cooking device can perform the display mode of the recommended cooking area when an approval command for performing the display mode of the recommended cooking area is received through the input interface (121).

[0470] It is also possible to identify a recommended cooking area based on at least one of the container identification information and cooking history information, as well as recipe information, food cooking status information, cooking course, number of containers, and cooking time information, and to display the identified recommended cooking area through a second output interface. A specific explanation of this is described in FIG. 13 and FIG. 26, so a specific explanation here is omitted.

[0471] When a cooking device receives a rejection command for a suggestion to display a recommended cooking area through an input interface (121), it can identify a cooking area based on the priority of preset cooking areas and display the identified cooking area through a second output interface (310).

[0472] The priority of the preset cooking area may be information stored during the manufacture of the cooking device.

[0473] FIG. 28 is an exemplary diagram of a cooking device according to another embodiment.
