Hood device, cooking device, and cooking control method using the same

[0001] Various embodiments of the present disclosure relate to cooking control technology, and more particularly, to a hood device, a cooking device, and a cooking control method using the same.

[0002] Technological advancements in cooking appliances and hoods have significantly improved cooking efficiency and safety in the kitchen. Cooking appliances such as induction cooktops and electric ovens can be combined with various sensor technologies to provide users with enhanced cooking options. Furthermore, hoods can maximize the functionality and effectiveness of cooking appliances by efficiently removing steam, smoke, and odors generated during the cooking process.

[0003] Recently, cooking systems have been proposed that integrate cooking devices and hoods to enhance the cooking process. For example, a cooking system can automatically adjust the hood's suction power based on the amount of heat and smoke generated by the cooking device, thereby maintaining an optimal cooking environment. By interlocking the cooking device and hood, the cooking system can increase the energy efficiency of the cooking process and enhance the user's cooking experience.

[0004] Meanwhile, food can be overcooked for a variety of reasons during the cooking process. Overcooking not only compromises the taste and nutrition of food, but can also lead to energy waste and safety issues such as fire. Therefore, there is a growing need for a method that can accurately detect overcooking during the cooking process and take appropriate preventative measures.

[0005] Various embodiments of the present disclosure can provide a hood device, a cooking device, and a cooking control method using the same, which prevent overcooking of food and improve cooking safety by sensing a cooking area and a surrounding area during a cooking process.

[0007] A cooking device for preventing overcooking according to embodiments of the present disclosure may include an input unit, a cooking unit, a communication unit, and at least one processor. The at least one processor may initiate cooking based on a user input, receive overcooking sensing data of food from a hood device, and, if the food is in an overcooked state, perform cooking control based on an overcooking prevention mode.

[0008] A cooking control method for preventing overcooking according to embodiments of the present disclosure may include an operation in which a cooking device starts cooking based on a user input, an operation in which a hood device senses whether food is in an overcooked state, an operation in which the hood device transmits overcooking sensing data of the food to the cooking device, and an operation in which the cooking device performs cooking control based on an overcooking prevention mode. The overcooking prevention mode may control at least one of a cooking speed or a cooking degree of the food based on the overcooking sensing data, thereby maintaining consistency in the cooking result of the food.

[0009] According to various embodiments of the present disclosure, the hood device, the cooking device, and the cooking control method using the same of the present disclosure can effectively prevent overcooking of food by precisely sensing changes in displacement of food during the cooking process and automatically controlling cooking of food based on the sensing data in an overcooking prevention mode.

[0010] In addition, the hood device, cooking device, and cooking control method using the same of the present disclosure can improve cooking safety by detecting abnormal operation during the cooking process and automatically controlling the cooking of food according to the risk level of the abnormal operation in a safe cooking mode.

[0043] FIG. 1 is a conceptual diagram showing a cooking control system according to one embodiment of the present disclosure, and FIG. 2 is a flowchart showing the operation of a cooking control method according to one embodiment of the present disclosure.

[0044] Referring to FIGS. 1 and 2, the cooking control system may include a hood device (100) and a cooking device (200). The cooking control system may sense the cooking area and surrounding area during the cooking process by using the hood device (100) and the cooking device (200), prevent overcooking of food, and improve cooking safety.

[0045] A hood device (100) (e.g., a range hood) may be a ventilation device that exhausts or purifies smoke or odors generated from food during cooking through an exhaust pipe connected to the outdoors. For example, the hood device (100) may be placed above a cooking device (200).

[0046] The hood device (100) can suck in smoke or odor by the suction force generated by the exhaust fan (110) that is supplied with power and rotates.

The at least one cooking burner may heat food or a cooking vessel. Depending on the embodiment, the cooking device (200) may be referred to as either a gas range or an electric range. In particular, when the cooking device (200) is implemented as an electric range that generates heat by converting electrical energy into thermal energy, the cooking device (200) may be classified into an induction range, a hot plate, and a highlight range depending on the type of the heating element.

[0048] For example, induction cooktops utilize the principle of heat generation through induction when a cooking vessel comes into contact with a magnetic material. These ranges can be electric ranges that utilize dedicated magnetic containers. For example, a hotplate can be an electric range that directly heats a metal plate containing heating wires. For example, a highlighter can be an electric range that combines both a hotplate and induction, with heating wires distributed in a circular pattern to heat a ceramic heater.

[0049] As shown in FIG. 2, the cooking control system of the present disclosure can sense whether food is overcooked (S210) and perform cooking control depending on whether the food is overcooked (S220).

[0060] The sensor unit (120) may be configured to sense the cooking area and the surrounding area. For example, the sensor unit (120) may determine whether food is overcooked and the degree of overcooking by sensing the cooking area. For example, the sensor unit (120) may determine an abnormal operation of at least one of the cooking area or the surrounding area by sensing the cooking area and the surrounding area. The sensor unit (120) may include at least one of a LiDAR sensor, an IR sensor, a thermal imaging camera, and an RGB camera.

[0063] In one embodiment, the processor (140) may store commands or data received from another component (e.g., a communication unit (130)) in volatile memory, process the commands or data stored in the volatile memory, and store resulting data in non-volatile memory as at least part of data processing or calculation.

[0064] In one embodiment, the processor (140) may include a main processor (e.g., a central processing unit or an application processor) or a secondary processor (e.g., a graphics processing unit, a neural processing unit (NPU), or a communication processor) that can operate independently or in conjunction with the main processor. For example, the processor (140) may include at least one of a central processing unit (CPU), an application processor (AP), or a microprocessor.

[0065] According to one embodiment, the processor (140) can sense whether food is in an overcooked state and control the cooking device (200) to prevent overcooking of food by transmitting a control signal to the cooking device (200). For example, the processor (140) can recognize the start of cooking of the cooking device (200). The processor (140) can sense whether food is in an overcooked state using the sensor unit (120). When the processor (140) senses that the food is in an overcooked state, the processor (140) can control the cooking device (200) based on an overcooking prevention mode.

[0066] Meanwhile, the processor (140) may control the communication unit (130) to transmit status information of the hood device (100) to the cooking device (200). Here, the status information of the hood device (100) may include information on the driving status of the exhaust fan (110), the driving strength level of the exhaust fan (110), etc. In addition, as another embodiment of the present invention, the hood device (100) may further include a lighting unit (not shown), and in this case, the status information of the hood device (100) may further include information on the driving status (ON / OFF status) of the lighting unit.

[0067] Meanwhile, the hood device (100) according to another embodiment of the present invention may further include an input unit (210) and a display unit. The input unit (210) is configured to receive a control command for controlling the hood device (100), and may receive control commands such as driving the exhaust fan (110), the driving intensity level of the exhaust fan (110), driving the lighting unit, and pairing connection with the cooking device (200).

The communication unit (230) includes a communication circuit, and the communication circuit may include at least one hardware component (e.g., a modulator, a demodulator, an antenna, a transceiver) for supporting transmission and / or reception of a signal between the cooking device (200) and an external electronic device (e.g., the hood device (100)). The communication unit (230) may include a wireless communication unit (230) (e.g., a cellular communication module, a short-range wireless communication module, or a GNSS (global navigation satellite system) communication module) or a wired communication unit (230). For example, the wireless communication unit (230) may communicate with at least one external server or hood device (100) via a network (e.g., a long-distance communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). Additionally, the communication unit (230) can communicate with an external server or hood device (100) using at least one communication method among NFC, Wi-Fi, Wi-Fi Direct, and Bluetooth.

[0073] However, the communication method between the cooking device (200) and the hood device (100) is not limited to the above-described embodiment, and the cooking device (200) and the hood device (100) can communicate with each other using various communication methods such as wired communication or wireless communication.

[0074] The processor (240) may, for example, execute software (e.g., a program) to control at least one other component (e.g., a hardware or software component) of a display device connected to the processor (240) and perform various data processing or calculations. For example, the processor (240) may control at least one of the input unit (210), the cooking unit (220), and the communication unit (230).

[0077] In one embodiment, the processor (240) may perform cooking control to prevent overcooking of food based on sensing data received from an external sensor (e.g., hood device (100)). For example, the processor (240) may initiate cooking based on a user input. For example, the processor (240) may receive overcooking sensing data of food from an external sensor. For example, if the food is overcooked, the processor (240) may perform cooking control based on an overcooking prevention mode.

[0078] FIG. 5 is a diagram showing a hood device (100) for preventing overcooking according to one embodiment of the present disclosure, FIG. 6 is a flowchart showing the operation of the hood device (100) according to one embodiment of the present disclosure, FIG. 7 is a diagram showing a cooking area (CA) and a surrounding area (SA) according to one embodiment of the present disclosure, FIG. 8 is a diagram showing an operation of the hood device (100) according to one embodiment of the present disclosure to sense whether food is in an overcooked state, and FIG. 9 is a diagram showing an operation of the hood device (100) according to one embodiment of the present disclosure to control the cooking device (200) based on an overcooking prevention mode.

[0079] Referring to FIGS. 5 to 9, the hood device (100) for preventing overcooking of the present disclosure may include an exhaust fan, a sensor, a communication unit, and at least one processor. The hood device (100) may recognize the start of cooking of the cooking device (200) (operation 610), sense whether food is in an overcooked state (operation 620), and determine whether food is in an overcooked state (operation 630). As the food is sensed to be in an overcooked state, the hood device (100) may transmit (640) a control signal for controlling the cooking device (200) to the cooking device (200) in an overcooking prevention mode. In addition, the hood device (100) may determine whether cooking of the food (1) is completed (operation 650).

[0080] According to an example, in operation 610, the hood device (100) can recognize the start of cooking of the cooking device (200). For example, the hood device (100) can sense a cooking area (CA) and a surrounding area (SA) using the sensor unit (120). As shown in FIG. 7, the cooking area (CA) is an area where food (1) is cooked and may be an upper area of ​​the cooking device (200). For example, the cooking area (CA) may include a cooking zone (CZ) including at least one cooking burner (CB), and a control panel (CP) including a user input unit. The surrounding area (SA) may be an area within a predetermined distance from the cooking device (200) in addition to the cooking area (CA).

[0081] Specifically, the hood device (100) can recognize the start of cooking of the cooking device (200) by sensing the cooking area (CA) and the surrounding area (SA). For example, the hood device (100) can recognize the start of cooking by identifying the user's approach in the surrounding area (SA) and the user's operation of turning on the power of the operation panel in the cooking area (CA). For example, the hood device (100) can recognize the start of cooking by sensing a temperature rise of the food (1) or a temperature rise of the cooking area (CA). For example, the hood device (100) can recognize the start of cooking by sensing a change in displacement (CiD) of the food (1) in the cooking area (CA). For example, the hood device (100) can recognize the start of cooking by receiving a cooking start signal from the cooking device (200).

[0082] In one example, in operation 620, the hood device (100) can sense whether the food is overcooked. For example, the hood device (100) can sense whether the food is overcooked using the sensor unit (120). The sensor unit (120) can include at least one of a LiDAR sensor, an IR sensor, a thermal imaging camera, and an RGB camera.

[0083] For example, the hood device (100) can precisely measure the distance to food (1) in the cooking area (CA) using a lidar sensor. The hood device (100) can sense overcooking by sensing physical changes in food (1) inside a cooking container (2) or a lid on the cooking container (2) using a lidar sensor.

[0084] For example, the hood device (100) can precisely measure the temperature of a cooking vessel (2) or food (1) in a cooking area (CA) using an IR sensor. The hood device (100) can sense whether the food is overcooked by sensing a change in the temperature of the cooking vessel (2) or food (1) using an IR sensor.

[0085] For example, the hood device (100) can visually capture the heat distribution of the cooking area (CA) using a thermal imaging camera. The hood device (100) can sense whether the food is overcooked by monitoring the heat distribution of the cooking container (2) or food (1) using the thermal imaging camera.

[0086] For example, the hood device (100) can precisely measure color changes in food (1) in the cooking area (CA) using an RGB camera. The hood device (100) can sense whether the food is overcooked by sensing color changes in the food (1) being cooked using an RGB camera.

[0087] For example, in operation 630, the hood device (100) can determine whether food is overcooked. As shown in FIG. 8, the hood device (100) can determine whether food is overcooked based on a change in displacement (CiD) of the food (1) or the container lid (3).

[0088] For example, the hood device (100) can capture the initial state of the food (1) when cooking starts. The hood device (100) can monitor the change in displacement (CiD) of the food (1) by comparing the cooking state of the food (1) being cooked with the initial state. For example, the hood device (100) can continuously sense the change in displacement (CiD) of the food (1) contained in the cooking container (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera. The hood device (100) can determine that the food (1) is overcooked when the change in displacement (CiD) of the food (1) contained in the cooking container (2) increases by more than a reference change amount.

[0089] For example, the hood device (100) can capture the initial displacement of the container lid (3) when cooking starts. The hood device (100) can monitor the change in displacement (CiD) of the container lid (3) by comparing the cooking displacement of the container lid (3) during cooking with the initial displacement. For example, the hood device (100) can continuously sense the change in displacement (CiD) of the container lid (3) on the cooking container (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera. The hood device (100) can determine that the food (1) is overcooked when the change in displacement (CiD) of the container lid (3) on the cooking container (2) increases by more than a reference change amount.

[0090] According to an example, in operation 640, when it is sensed that the food is in an overcooked state, the hood device (100) can transmit a control signal to the cooking device (200) in an overcooking prevention mode to control the cooking device (200). The overcooking prevention mode can maintain consistency in the cooking result of the food (1) by controlling at least one of the cooking speed or the cooking degree of the food (1) based on the overcooking sensing data.

[0091] The hood device (100) can divide the change in displacement (CiD) into predetermined sections based on at least one of the cooking vessel (2), the recipe of the food (1), or the burner in use. For example, the hood device (100) can divide the change in displacement (CiD) into a first section (e.g., overcooking expected), a second section (e.g., overcooking starting), a third section (overcooking in progress), and a fourth section (e.g., severe overcooking). The hood device (100) can determine the degree of overcooking of the food based on the sections of the change in displacement (CiD).

[0092] In one embodiment, the hood device (100) can divide the change in displacement (CiD) of the food (1) or the container lid (3) into predetermined sections based on at least one of the type, material, and shape of the cooking container (2). For example, the hood device (100) can identify at least one of the type, material, and shape of the cooking container (2), and determine the degree of overcooking of the food by considering the influence of at least one of the type, material, and shape of the cooking container (2) on the change in displacement (CiD).

[0093] In one embodiment, the hood device (100) can divide the change in displacement (CiD) of the food (1) or the container lid (3) into predetermined sections based on the recipe of the food (1). For example, the hood device (100) can receive the recipe of the food (1) and determine the degree of overcooking of the food by considering the effect of the recipe of the food (1) on the change in displacement (CiD).

[0094] In one embodiment, the hood device (100) can divide the change in displacement (CiD) of the food (1) or the container lid (3) into predetermined sections based on at least one of the number, arrangement, and movement of the burners in use. For example, the hood device (100) can identify at least one of the number, arrangement, and movement of the burners in use, and determine the degree of overcooking of the food by considering the effect of at least one of the number, arrangement, and movement of the burners in use on the change in displacement (CiD).

[0095] The hood device (100) can control the cooking device (200) in response to the degree of overcooking of the food in the overcooking prevention mode. Specifically, as shown in FIG. 9, the hood device (100) can transmit a control signal (CONT) to the cooking device (200) in the overcooking prevention mode.

[0096] The hood device (100) can control the cooking device (200) to provide an overcooking notification (910) corresponding to the degree of overcooking of the food. For example, the hood device (100) can control the cooking device (200) to provide an overcooking prediction notification (910) (e.g., “food (1) starts boiling”) when the change in displacement (CiD) is in the first section (e.g., overcooking prediction).

[0097] The hood device (100) can control the cooking device (200) so that the cooking device (200) adjusts the cooking temperature (920) in response to the degree of overcooking of the food. For example, the hood device (100) can control the cooking device (200) so that the cooking device (200) adjusts the cooking temperature (920) (e.g., lowers it from 15 to 5) when the change in displacement (CiD) is in the second section (e.g., starts overcooking).

[0098] The hood device (100) can control the cooking device (200) so that the cooking device (200) adjusts the cooking time (930) in response to the degree of overcooking of the food. For example, the hood device (100) can control the cooking device (200) so that the cooking device (200) adjusts the cooking time (930) (e.g., ends after 5 minutes) when the change in displacement (CiD) is in the third section (overcooking in progress).

[0099] The hood device (100) can cut off the power (940) of the cooking device (200) in response to the degree of overcooking of the food. For example, the hood device (100) can control the cooking device (200) to cut off the power (940) (e.g., turn off) when the change in displacement (CiD) is in the fourth section (e.g., severe overcooking).

[0100] According to an example, in operation 650, the hood device (100) can determine whether cooking of the food (1) is complete. For example, the hood device (100) can sense whether cooking of the food (1) is complete using the sensor unit (120). If cooking of the food (1) is not complete, the hood device (100) can continuously sense whether the food is overcooked. If cooking of the food (1) is complete, the hood device (100) can control the cooking device (200) to cut off power to the cooking device (200).

[0101] In this way, the hood device (100) of the present disclosure can effectively prevent overcooking of food by precisely sensing the change in displacement (CiD) of food (1) during the cooking process and automatically controlling the cooking of food (1) based on the sensing data in the overcooking prevention mode.

[0102] FIG. 10 is a flowchart showing the operation of a hood device (100) according to one embodiment of the present disclosure, FIG. 11 is an exemplary diagram showing the hood device (100) according to one embodiment of the present disclosure detecting an abnormal operation, FIG. 12 is an exemplary diagram showing the hood device (100) according to one embodiment of the present disclosure detecting an abnormal operation, and FIG. 13 is a diagram explaining the operation of the hood device (100) according to one embodiment of the present disclosure controlling the cooking device (200) based on a safe cooking mode.

[0103] Referring to FIGS. 10 to 13, the hood device (100) can detect an abnormal operation of at least one of the cooking area (CA) and the surrounding area (SA) (operation 1010) and control the cooking device (200) based on a safe cooking mode (operation 1020).

[0104] In one example, at operation 1010, the hood device (100) may detect an abnormal operation in at least one of the cooking area (CA) and the surrounding area (SA). For example, the abnormal operation may include at least one of an object approaching the cooking device (200), overflow of the food (1), movement of the cooking vessel (2), or an unintended input.

[0105] As shown in Fig. 11, the hood device (100) can identify an object (e.g., an animal or a child) approaching the cooking device (200) by sensing the surrounding area (SA). For example, the hood device (100) can identify the type of object based on at least one of the object's size, shape, movement path, and movement pattern. For example, the hood device (100) can identify the type of object using an artificial intelligence model that has learned the type of object.

[0106] In one embodiment, the hood device (100) can identify overflow of food (1) or movement of a cooking vessel (2) by sensing a cooking zone (CZ) of a cooking area (CA). For example, the hood device (100) can identify overflow of food (1) in a cooking vessel (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera. For example, the hood device (100) can identify movement of a cooking vessel (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera.

[0107] As shown in Fig. 12, the hood device (100) can determine an unintended input by sensing the surrounding area (SA) and the cooking area (CA). For example, the hood device (100) can sense the operation panel (CP) in the cooking area (CA) when a new user input is received when there is no user in the surrounding area (SA). The hood device (100) can determine whether the new user input is an unintended input (e.g., input by water, input by a cooking tool).

[0108] For example, in operation 1020, the hood device (100) may control the cooking device (200) based on a safety cooking mode. For example, the safety cooking mode may be a control mode for preventing malfunction of the cooking device (200) due to abnormal operation.

[0109] The hood device (100) can classify the risk level of the abnormal operation into at least one of Level 1, Level 2, Level 3, or Critical. For example, Level 1 may be a level where the risk of the abnormal operation to the cooking process is minor. For example, Level 2 may be a level where the risk of the abnormal operation to the cooking process is at a level where it must be eliminated. For example, Level 3 may be a level where the risk of the abnormal operation to the cooking process is serious. For example, the Critical level may be a level where the risk of the abnormal operation to the cooking process is critical.

[0110] The hood device (100) can control the cooking device (200) in the safe cooking mode so that the cooking device (200) performs at least one of providing a notification, adjusting the heat, pausing cooking, or cutting off power in response to the risk level. For example, as shown in FIG. 13, the hood device (100) can control the cooking device (200) in the first step so that the cooking device (200) provides a notification of abnormal operation. For example, the hood device (100) can control the cooking device (200) in the second step so that the cooking device (200) adjusts the heat. For example, the hood device (100) can control the cooking device (200) in the third step so that the cooking device (200) pauses cooking. For example, the hood device (100) can control the cooking device (200) in the emergency step so that the cooking device (200) cuts off power.

[0111] In this way, the hood device (100) of the present disclosure can improve cooking safety by detecting abnormal behavior during the cooking process and automatically controlling the cooking of food (1) according to the risk level of the abnormal behavior in a safe cooking mode. Accordingly, the hood device (100) of the present disclosure can improve the cooking quality of food (1), minimize energy use, and ensure kitchen safety.

[0112] FIG. 14 is a drawing showing a cooking device (200) for preventing overcooking according to one embodiment of the present disclosure, FIGS. 15a and 15b are drawings showing an external sensor (300) of the cooking device (200) according to one embodiment, FIG. 16 is a flowchart showing the operation of the cooking device (200) according to one embodiment of the present disclosure, FIG. 17 is a drawing showing a cooking area (CA) and a surrounding area (SA) according to one embodiment of the present disclosure, FIG. 18 is a drawing showing an operation of the external sensor (300) according to one embodiment of the present disclosure to sense whether food is in an overcooked state, and FIG. 19 is a drawing showing an operation of the cooking device (200) according to one embodiment of the present disclosure to perform cooking control based on an overcooking prevention mode.

[0113] Referring to FIGS. 14 to 19, a cooking device (200) for preventing overcooking of the present disclosure may include an input unit, a cooking unit, a communication unit, and at least one processor. The cooking device (200) may start cooking based on a user input (1610), receive overcooking sensing data of food from an external sensor (300) (1620), and determine whether the food is overcooked (operation 1630). If the food (1) is overcooked, the cooking device (200) may perform cooking control based on an overcooking prevention mode (operation 1640). In addition, the cooking device (200) may determine whether cooking of the food (1) is completed (operation 1650).

[0114] In one example, at operation 1610, the cooking device (200) may start cooking based on a user input. For example, the cooking device (200) may receive a user input through an input unit and start cooking based on the user input.

[0115] In one example, at operation 1620, the cooking device (200) may receive overcooking sensing data of food from an external sensor (300). For example, the external sensor (300) may be placed on top of the cooking device (200).

[0116] In one embodiment, as shown in FIG. 15A, the external sensor (300) may be attached to a support structure (SS) formed horizontally with the cooking device (200). The external sensor (300) may be attached to the support structure by a support member. For example, the external sensor (300) may be arranged on the upper portion of the cooking device (200) and parallel to the cooking device (200). In this case, the external sensor (300) may accurately sense the cooking area (CA) of the cooking device (200).

[0117] In one embodiment, as shown in FIG. 15b, the external sensor (300) may be attached to a support structure (SS) formed by extending from an object (e.g., a wall) in contact with the cooking device (200). The external sensor (300) may be attached to the support structure by a support member. For example, the external sensor (300) may be positioned on top of the cooking device (200) at a predetermined angle with respect to the cooking device (200). In this case, the external sensor (300) may be capable of widely sensing the surrounding area (SA) of the cooking device (200).

[0118] In one embodiment, the external sensor (300) may be a hood device (e.g., hood device (100) of FIG. 1). For example, the external sensor (300) may be a sensor unit included in the hood device (e.g., sensor unit (120) of FIG. 3). For example, the cooking device (200) may receive food overcooking sensing data from the hood device (100).

[0119] For example, the external sensor (300) can sense the cooking area (CA) and the surrounding area (SA) at the top of the cooking device (200). As shown in FIG. 17, the cooking area (CA) is an area where food (1) is cooked and may be an upper area of ​​the cooking device (200). For example, the cooking area (CA) may include a cooking zone (CZ) including at least one cooking burner (CB) and a control panel (CP) including a user input unit. The surrounding area (SA) may be an area within a predetermined distance from the cooking device (200) in addition to the cooking area (CA).

[0120] In one example, at operation 1620, the cooking device (200) may receive overcooking sensing data of food from an external sensor (300). For example, the external sensor (300) may sense whether the food is overcooked. The external sensor (300) may include at least one of a LiDAR sensor, an IR sensor, a thermal imaging camera, and an RGB camera.

[0121] For example, the external sensor (300) can precisely measure the distance to food (1) in the cooking area (CA) using a lidar sensor. The external sensor (300) can sense whether food is overcooked by sensing physical changes in the food (1) inside the cooking container (2) or the lid on the cooking container (2) using a lidar sensor.

[0122] For example, the external sensor (300) can precisely measure the temperature of a cooking vessel (2) or food (1) in the cooking area (CA) using an IR sensor. The external sensor (300) can sense whether the food is overcooked by sensing a change in the temperature of the cooking vessel (2) or food (1) using an IR sensor.

[0123] For example, the external sensor (300) can visually capture the heat distribution of the cooking area (CA) using a thermal imaging camera. The external sensor (300) can sense whether the food is overcooked by monitoring the heat distribution of the cooking container (2) or food (1) using a thermal imaging camera.

[0124] For example, an external sensor (300) can precisely measure color changes in food (1) in a cooking area (CA) using an RGB camera. The external sensor (300) can sense color changes in food (1) being cooked using an RGB camera, thereby sensing whether the food is overcooked.

[0125] As shown in Fig. 18, an external sensor (300) can sense whether food is overcooked and transmit overcooking sensing data (SENS) to a cooking device (200). The cooking device (200) can receive overcooking sensing data (SENS) of food from the external sensor (300).

[0126] For example, in operation 1630, the cooking device (200) can determine whether food is overcooked. As shown in FIG. 18, the cooking device (200) can determine whether food is overcooked based on the change in displacement (CiD) of the food (1) or the container lid (3) included in the overcooking sensing data (SENS).

[0127] For example, the external sensor (300) can capture the initial state of the food (1) when cooking starts. The external sensor (300) can monitor the change in displacement (CiD) of the food (1) by comparing the cooking state of the food (1) being cooked with the initial state. For example, the external sensor (300) can continuously sense the change in displacement (CiD) of the food (1) contained in the cooking container (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera. The cooking device (200) can determine that the food (1) is overcooked when the change in displacement (CiD) of the food (1) contained in the cooking container (2) increases by more than a reference change amount.

[0128] For example, the external sensor (300) can capture the initial displacement of the container lid (3) when cooking starts. The external sensor (300) can monitor the change in displacement (CiD) of the container lid (3) by comparing the cooking displacement of the container lid (3) during cooking with the initial displacement. For example, the external sensor (300) can continuously sense the change in displacement (CiD) of the container lid (3) on the cooking container (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera. The cooking device (200) can determine that the food (1) is overcooked when the change in displacement (CiD) of the container lid (3) on the cooking container (2) increases by more than a reference change amount.

[0129] According to an example, in operation 1640, when it is sensed that the food is in an overcooked state, the cooking device (200) can perform cooking control based on an overcooking prevention mode. The overcooking prevention mode can maintain consistency in the cooking result of the food (1) by controlling at least one of the cooking speed or cooking degree of the food (1) based on overcooking sensing data.

[0130] The cooking device (200) can divide the change in displacement (CiD) into predetermined sections based on at least one of the cooking vessel (2), the recipe of the food (1), or the burner in use. For example, the cooking device (200) can divide the change in displacement (CiD) into a first section (e.g., overcooking expected), a second section (e.g., overcooking start), a third section (overcooking in progress), and a fourth section (e.g., severe overcooking). The cooking device (200) can determine the degree of overcooking of the food based on the sections of the change in displacement (CiD).

[0131] In one embodiment, the cooking device (200) can divide the change in displacement (CiD) of the food (1) or the container lid (3) into predetermined sections based on at least one of the type, material, and shape of the cooking container (2). For example, the cooking device (200) can identify at least one of the type, material, and shape of the cooking container (2), and determine the degree of overcooking of the food by considering the influence of at least one of the type, material, and shape of the cooking container (2) on the change in displacement (CiD).

[0132] In one embodiment, the cooking device (200) can divide the change in displacement (CiD) of the food (1) or the container lid (3) into predetermined sections based on the recipe of the food (1). For example, the cooking device (200) can receive the recipe of the food (1) and determine the degree of overcooking of the food by considering the effect of the recipe of the food (1) on the change in displacement (CiD).

[0133] In one embodiment, the cooking device (200) can divide the change in displacement (CiD) of the food (1) or the container lid (3) into predetermined sections based on at least one of the number, arrangement, and movement of the burners in use. For example, the cooking device (200) can identify at least one of the number, arrangement, and movement of the burners in use, and determine the degree of overcooking of the food by considering the effect of at least one of the number, arrangement, and movement of the burners in use on the change in displacement (CiD).

[0134] The cooking device (200) can perform cooking control based on an overcooking prevention mode in response to the degree of overcooking of the food. Specifically, as shown in FIG. 19, the cooking device (200) can perform at least one of an overcooking notification, cooking temperature adjustment, cooking time adjustment, or power cutoff in the overcooking prevention mode.

[0135] The cooking device (200) may provide an overcooking notification (1910) corresponding to the degree of overcooking of the food. For example, the cooking device (200) may provide an overcooking prediction notification (1910) (e.g., “food (1) begins to boil”) when the change in displacement (CiD) is in the first section (e.g., overcooking prediction).

[0136] The cooking device (200) can adjust the cooking temperature (1920) in response to the degree of overcooking of the food. For example, the cooking device (200) can adjust the cooking temperature (1920) (e.g., lowering it from 15 to 5) when the change in displacement (CiD) is in the second section (e.g., the start of overcooking).

[0137] The cooking device (200) can adjust the cooking time (1930) in response to the degree of overcooking of the food. For example, the cooking device (200) can adjust the cooking time (1930) (e.g., end after 5 minutes) when the change in displacement (CiD) is in the third section (overcooking in progress).

[0138] The cooking device (200) can cut off the power supply (1940) in response to the degree of overcooking of the food. For example, the cooking device (200) can cut off the power supply (1940) (e.g., turn it off) when the change in displacement (CiD) is in the fourth section (e.g., severe overcooking).

[0139] For example, in operation 1650, the cooking device (200) can determine whether cooking of the food (1) is complete. For example, the cooking device (200) can sense whether cooking of the food (1) is complete using an external sensor (300). If cooking of the food (1) is not complete, the cooking device (200) can continuously sense whether the food is overcooked using the external sensor (300). If cooking of the food (1) is complete, the cooking device (200) can cut off the power.

[0140] In this way, the cooking device (200) of the present disclosure can effectively prevent overcooking of food by precisely sensing the change in displacement (CiD) of food (1) during the cooking process and automatically controlling the cooking of food (1) based on the sensing data in the overcooking prevention mode.

[0141] FIG. 20 is a flowchart showing the operation of a cooking device (200) according to one embodiment of the present disclosure, FIG. 21 is an example diagram showing an external sensor (300) according to one embodiment of the present disclosure detecting an abnormal operation, FIG. 22 is an example diagram showing an external sensor (300) according to one embodiment of the present disclosure detecting an abnormal operation, and FIG. 23 is a diagram explaining an operation of a cooking device (200) according to one embodiment of the present disclosure performing cooking control based on a safe cooking mode.

[0142] Referring to FIGS. 20 to 23, the cooking device (200) can receive abnormal motion sensing data of at least one of the cooking area (CA) and the surrounding area (SA) from an external sensor (300) (operation 2010) and perform cooking control based on a safe cooking mode (operation 2020).

[0143] In one example, in operation 2010, the external sensor (300) may detect an abnormal operation in at least one of the cooking area (CA) and the surrounding area (SA). For example, the abnormal operation may include at least one of an object approaching the cooking device (200), overflow of the food (1), movement of the cooking vessel (2), or an unintended input.

[0144] As shown in Fig. 21, the external sensor (300) can sense an object (e.g., an animal or a child) approaching the cooking device (200) by sensing the surrounding area (SA). For example, the cooking device (200) can identify the type of the object based on at least one of the object's size, shape, movement path, and movement pattern. For example, the cooking device (200) can identify the type of the object using an artificial intelligence model that has learned the type of the object.

[0145] In one embodiment, the external sensor (300) can sense overflow of food (1) or movement of the cooking vessel (2) by sensing the cooking zone (CZ) of the cooking area (CA). For example, the external sensor (300) can sense overflow of food (1) in the cooking vessel (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera. For example, the external sensor (300) can sense movement of the cooking vessel (2) using at least one of a lidar sensor, an IR sensor, a thermal imaging camera, and an RGB camera.

[0146] As shown in Fig. 22, the cooking device (200) can determine unintended input from abnormal motion sensing data. For example, the external sensor (300) can sense the operation panel (CP) in the cooking area (CA) when a new user input is received when there is no user in the surrounding area (SA). The cooking device (200) can determine whether the new user input is an unintended input (e.g., input by water, input by a cooking tool).

[0147] For example, in operation 2020, the cooking device (200) may perform cooking control based on a safety cooking mode. For example, the safety cooking mode may be a control mode for preventing malfunction of the cooking device (200) due to abnormal operation.

[0148] The cooking device (200) may classify the risk level of the abnormal operation into at least one of a first level, a second level, a third level, or an emergency level. For example, the first level may be a level where the risk of the abnormal operation to the cooking process is minor. For example, the second level may be a level where the risk of the abnormal operation to the cooking process is at a level where it must be eliminated. For example, the third level may be a level where the risk of the abnormal operation to the cooking process is serious. For example, the emergency level may be a level where the risk of the abnormal operation to the cooking process is critical.

[0149] In the safe cooking mode, the cooking device (200) may perform at least one of providing a notification, adjusting the heat, pausing cooking, or cutting off power in response to the risk level. For example, as shown in FIG. 23, the cooking device (200) may provide a notification of abnormal operation in the first stage. For example, the cooking device (200) may adjust the heat in the second stage. For example, the cooking device (200) may pause cooking in the third stage. For example, the cooking device (200) may cut off power in the emergency stage.

[0150] In this way, the cooking device (200) of the present disclosure can improve cooking safety by detecting abnormal behavior during the cooking process and automatically controlling the cooking of food (1) according to the risk level of the abnormal behavior in a safe cooking mode. Accordingly, the cooking device (200) of the present disclosure can improve the cooking quality of food (1), minimize energy use, and ensure kitchen safety. However, since this has been described above, a redundant description thereof will be omitted.

[0151] A hood device for preventing overcooking according to embodiments of the present disclosure may include an exhaust fan, a sensor, a communication unit, and at least one processor. The at least one processor may recognize the start of cooking of a cooking device, sense whether food is in an overcooked state, and, when the food is sensed to be in an overcooked state, transmit a control signal to the cooking device for controlling the cooking device in an overcooking prevention mode.

[0152] In one embodiment, the overcooking prevention mode can maintain consistency in the cooking result of the food by controlling at least one of the cooking speed or the cooking degree of the food based on the overcooking sensing data.

[0153] In one embodiment, the at least one processor can capture an initial state of the food when the cooking starts, compare the cooking state of the food being cooked with the initial state, monitor a change in displacement of the food, and determine whether the food is overcooked based on the change in displacement.

[0154] In one embodiment, the at least one processor can divide the change in displacement into predetermined sections based on at least one of the cooking vessel, the recipe of the food, or the burner in use, and determine the degree of overcooking of the food based on the predetermined sections.
