[0037] FIGS. 1a to 1c are drawings for explaining the structure and operation of a microwave oven to aid in understanding the present disclosure.
[0038] Referring to FIGS. 1a to 1c, the microwave oven (1) is formed in a roughly rectangular shape with a cooking chamber (22) inside, and the outer shape of both sides and the top surface can be formed by a sub-case (10). The sub-case (10) is formed by bending a plate having a predetermined width and thickness, and can be combined with a rear plate (12) forming the outer shape of the rear of the microwave oven (1) and a lower plate (14) forming the outer shape of the bottom surface. A cavity (20) forming a cooking chamber (22), which is a space for cooking food, can be provided on the upper side of the lower plate (14). The cavity (20) can be formed in a rectangular cylindrical shape with an open front surface, sized to be accommodated inside the outer case (10). That is, the cavity (20) is formed in a cylindrical shape by joining plates forming at least one side together, and the cooking chamber (22) can be formed inside the open space.
[0039] A heater (40) for heating food contained in the cooking chamber (22) with radiant heat may be provided on the ceiling of the cooking chamber (22). A sheathe heater is generally used as the heater (40), and various types of electric heaters such as ceramic heaters and halogen heaters may be used as needed. The heater (40) may be fixed to a top cavity (24) that forms the upper surface of the cavity (20) so as to be exposed into the cooking chamber (22).
[0040] Meanwhile, a turntable (32) that supports a container holding food may be provided on the floor of the cooking chamber (22). A turntable motor (33) may be provided on the lower side of the turntable (32). The turntable motor (33) provides driving force for the rotation of the turntable (32) when food is being cooked inside the cooking chamber (22). The turntable motor (33) stops when food is being kept warm inside the cooking chamber (22) so that unnecessary power is not consumed. A cooking chamber lamp (35) may be further provided on the side of the cooking chamber (22). When food is being cooked inside the cooking chamber, the cooking chamber lamp (35) illuminates the inside of the cooking chamber (22) so that the user can know the cooking status of the food. When food inside the cooking chamber is being kept warm, the cooking chamber lamp (35) turns off so that unnecessary power is not consumed.
[0041] Additionally, a plurality of intake holes (28) for sucking in air inside the cooking chamber (22) are formed in the central part of the back cavity (26) forming the rear of the cooking chamber (22), and a plurality of discharge holes (29) for discharging heat generated by the convection heater (62) into the cooking chamber (22) can be formed on the inner edge of the back cavity (26).
[0042] Meanwhile, an electrical chamber (30) may be provided in the top cavity (24) and the back cavity (26). The electrical chamber (30) is a space equipped with electrical components for operating the microwave oven (1). The electrical chamber (30) formed in the back cavity (26) may be equipped with a magnetron (34) that generates microwaves for heating food, a high-voltage transformer and a high-voltage capacitor for supplying high-voltage current to the magnetron (34), and a convection unit (60) that heats the cooking chamber (22) by convection.
[0043] The convection section (60) may be configured to include a convection heater (62) that generates heat through electrical resistance and a convection fan (64) that forcibly convects the heat generated by the convection heater (62) into the cooking chamber (22). When the convection function of the microwave oven (1) is performed, power is applied to the convection heater (62) so that the convection heater (62) generates heat, and the heat generated by the convection heater (62) can circulate inside the cooking chamber (22) by the rotation of the convection fan (64). That is, food contained in the cooking chamber (22) can be cooked through a convection heating process in which the heat generated by the convection heater (62) is introduced into the cooking chamber (22) through the discharge port (29) and then discharged outside the cooking chamber (22) through the intake port (28).
[0044] Meanwhile, the electrical chamber (30) formed on the upper surface of the top cavity (24) may be equipped with a control unit (or processor) (50) that controls the overall operation of the heater (40) and the microwave oven (1), and a fan assembly (70) that forces air flow to cool the electrical chamber (30).
[0045] The control unit (50) can form a predetermined circuit using a number of circuit components such as resistors, capacitors, IC (Integrated Circuit) chips, and MICOMs.
[0046] The fan assembly (70) draws in external air from the microwave oven (1) by rotational force to cool a number of electrical components provided in the electrical chamber (30), and a portion of this air is introduced into the cooking chamber (22) through an inlet (27) formed on the front side of the top cavity (24) and circulates inside the cooking chamber (22). The air circulating inside the cooking chamber (22) can be discharged to the outside of the cooking chamber (22) through an intake port (28).
[0047] Meanwhile, a front plate (16) may be formed at the front of the cavity (20). The front plate (16) forms the front outer shape of the cavity (20) and can be combined with the front end of the outer case (10). A door (80) may be rotatably connected to the front plate (16). The door (80) is hinge-connected to the bottom of the front plate (16) to selectively open and close the open front of the cavity (20).
[0048] A viewing window (82) may be formed in the central part of the door (80) to allow the user to view the cooking status of the food inside the cooking chamber (22) without rotating the door (80). Additionally, a door handle (84) that is grasped by the user may be provided on the front of the door (80) to facilitate opening and closing of the door (80). Meanwhile, an operating unit (90) may be provided on the upper part of the door (80) for the user to input operation commands to cook food or keep food warm using the microwave oven (1). The operating unit (90) may be configured to include a plurality of buttons (92) for operating the microwave oven (1) and a display (94) indicating the operating status. The display (94) may show the status of the microwave oven (1) set by the buttons (92).
[0049] FIG. 2 is a block diagram showing the configuration of a cooking device according to one embodiment.
[0050] According to one embodiment, the cooking device (100) may be implemented as a different type of device including a microwave oven (e.g., microwave oven (1) of FIGS. 1a to 1c) or an oven. According to one example, the cooking device (100) may be implemented as a device that cooks food while rotating the turntable (120, e.g., turntable (32) of FIGS. 1a to 1c) by including a turntable (120, e.g., turntable (32) of FIGS. 1a to 1c). However, for the convenience of explanation, the following description is limited to the case where the cooking device (100) is implemented as a microwave oven.
[0051] At least one sensor (110, hereinafter referred to as the sensor) may include a plurality of sensors of various types. The sensor (110) may measure physical quantities or detect the operating state of the cooking device (100) and convert the measured or detected information into an electrical signal. The sensor (110) may include a camera, and the camera may include a lens that focuses visible light or other optical signals received by being reflected by an object onto an image sensor, and an image sensor capable of detecting visible light or other optical signals. Here, the image sensor may include a 2D pixel array divided into a plurality of pixels. Alternatively, at least one sensor (110) may include a temperature sensor or an infrared sensor. According to one example, the sensor (110) may be implemented as a thermal imaging camera. Alternatively, according to one example, the sensor (110) may include a contact sensor for detecting the presence of a cooking vessel on a rotating plate by recognizing the contact surface of the rotating plate.
[0052] According to one embodiment, the turntable (120) may be provided on one side of the cooking device (100). According to one example, the turntable (120) may be provided on the floor of the cooking chamber.
[0053] At least one processor (130) (hereinafter, processor) is electrically connected to at least one sensor (110), a turntable (120), and a memory (140) to control the overall operation of the cooking device (100). The processor (130) may be composed of one or more processors. Specifically, the processor (130) may perform the operation of the cooking device (100) according to various embodiments of the present disclosure by executing at least one instruction stored in the memory (140).
[0054] According to one embodiment, the processor (130) may be implemented as a digital signal processor (DSP) that processes digital video signals, a microprocessor, a Graphics Processing Unit (GPU), an Artificial Intelligence (AI) processor, a Neural Processing Unit (NPU), or a Time Controller (TCON). However, it is not limited thereto, and may include or be defined by one or more of a central processing unit (CPU), a Micro Controller Unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a communication processor (CP), or an ARM processor. Additionally, the processor (130) may be implemented as a System on Chip (SoC) or Large Scale Integration (LSI) with a built-in processing algorithm, or may be implemented in the form of an Application Specific Integrated Circuit (ASIC) or Field Programmable Gate Array (FPGA).
[0055] The memory (140) can store data necessary for various embodiments. Depending on the purpose of data storage, the memory (140) may be implemented in the form of a memory embedded in the cooking device (100) or in the form of a memory that can be attached to and detached from the cooking device (100). For example, data for operating the cooking device (100) may be stored in a memory embedded in the cooking device (100), and data for the expansion function of the cooking device (100) may be stored in a memory that can be attached to and detached from the cooking device (100).
[0056] Meanwhile, the memory embedded in the cooking device (100) may be implemented as at least one of volatile memory (e.g., DRAM (dynamic RAM), SRAM (static RAM), or SDRAM (synchronous dynamic RAM), etc.), 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, etc.), hard drive, or solid state drive (SSD). Additionally, the memory that is detachable from the cooking device (100) may be implemented in the form of a memory card (e.g., CF (compact flash), SD (secure digital), Micro-SD (micro secure digital), Mini-SD (mini secure digital), xD (extreme digital), MMC (multi-media card), etc.), external memory connectable to a USB port (e.g., USB memory), etc. there is.
[0057] According to one embodiment, the processor (130) may acquire sensing data. According to one example, the processor (130) may acquire sensing data from the sensor (110). According to one example, the sensing data may be data related to an object (e.g., a cooking vessel) existing inside the cooking chamber. For example, if the sensor (110) is implemented as a camera sensor, the processor (130) may acquire sensing data corresponding to an image inside the cooking chamber. Alternatively, for example, if the sensor (110) is implemented as a thermal imaging camera, the processor (130) may acquire sensing data corresponding to a thermal image inside the cooking chamber. However, it is not limited thereto, and the sensing data may be data of a different type related to information about an object existing inside the cooking chamber.
[0058] According to one embodiment, the processor (130) can identify the placement state of the cooking container at the time of cooking start. According to one example, the processor (130) can identify the placement state of the cooking container on the turntable (120) at the time of cooking start based on sensing data obtained through at least one sensor (110). According to one example, the cooking container may be a container (e.g., a cup or a bowl) containing a food (or a food). According to one example, the time of cooking start may be the time when the cooking device (100) starts a cooking operation based on user input to start cooking the food. According to one example, the placement state of the cooking container may include information regarding the placement direction of the cooking container within the cooking chamber and the shape of the cooking container. According to one example, the placement direction within the cooking chamber may be the direction in which a specific part of the cooking container (e.g., a handle) is facing, but is not limited thereto.
[0059] According to one example, the processor (130) can identify the arrangement state of the cooking vessel at the start of cooking based on a preset image analysis algorithm. For example, at least one sensor may be implemented as a camera sensor for acquiring an image of the cooking chamber. The processor (130) can identify the arrangement state of the cooking vessel, including the position of the handle (or the direction the handle is facing), at the start of cooking by inputting the sensing data acquired through the camera sensor into a preset image analysis algorithm.
[0060] According to one example, the pre-configured image analysis algorithm may be an algorithm that extracts feature points of an identified object when an object included in an image is identified (e.g., Generalized Hough Transform algorithm), but is not limited thereto, and the pre-configured image analysis algorithm may, of course, be implemented as a different type of algorithm that extracts the shape of an object included in an image and identifies the relative position of a handle included in a cooking container. The processor (130) can identify the arrangement state of the cooking container using the pre-configured image analysis algorithm.
[0061] According to one embodiment, the processor (130) can calculate a rotational speed. According to one example, if a first placement direction that facilitates the removal of a cooking container is identified based on an identified placement state, the processor (130) can calculate a rotational speed for the cooking container to be placed in the first placement direction at the time of completion of cooking. According to one example, the first placement direction may mean a direction in which a specific part of the cooking container (e.g., a handle) faces toward the door (e.g., the door (80) in FIGS. 1a to 1c), but is not limited thereto. According to one example, the first placement direction may be the placement direction of the cooking container at the time of start of cooking. This will be explained in detail through FIGS. 11a and 11b.
[0062] According to one example, the rotation speed may refer to the speed at which the turntable (120) rotates during the time the food is cooked (or, cooking time). According to one example, the rotation speed for the cooking vessel to be placed in the first placement direction at the time the cooking is completed may be various values depending on the amount of rotation. For example, the amount of rotation for the cooking vessel to be placed in the first placement direction at the time the cooking is completed (or the amount of rotation of the turntable (120) during the cooking time) may be multiple values (e.g., 0.6 times, 1.6 times, and 2.6 times, etc.), and a rotation speed corresponding to each amount of rotation may be calculated. However, the rotation speed for placement in the first placement direction may be a rotation speed at which the error with the rotation speed corresponding to the basic operation mode is minimized in order to maintain the performance of the cooking device (100). This will be described later.
[0063] According to one example, the cooking vessel may be a directional vessel. For example, if the cooking vessel is implemented as a cup having at least one handle, the cooking vessel may have a directional quality. If the cooking vessel has at least one handle, the processor (130) can calculate a rotational speed for the handle to be positioned at a preset position (e.g., a position where the handle faces the door).
[0064] According to one example, the cooking start time may be the time when the cooking device begins the cooking operation. According to one example, the cooking completion time may be the time when the cooking device ends the cooking operation. According to one example, the cooking time may be the time from the cooking start time to the cooking completion time. According to one example, the cooking device may perform the cooking operation from the cooking start time to the cooking completion time. According to one example, the turntable may rotate during the cooking time, but is not limited thereto, and the turntable may rotate for a shorter time than the cooking time. This will be explained in detail through FIG. 7.
[0065] However, this is not limited thereto, and depending on the example, the cooking container may be a container that does not have a directionality. For example, if the cooking container is implemented as a cup that does not include a handle, the cooking container may not have a directionality. In this case, the processor (130) may identify the temperature at each location of the cooking container and identify the rotation speed so that the location with the relatively lowest temperature is positioned toward the door. This will be described later.
[0066] According to one embodiment, the processor (130) can control the turntable (120) based on the calculated rotation speed. According to one example, if the cooking time is 2 minutes and the amount of rotation is calculated to be 5.6 times, the processor (130) can rotate the turntable (120) at a rotation speed of 2.8 times per minute. According to one example, the processor (130) can control a drive unit (e.g., the turntable motor (33) of FIGS. 1a to 1c) to rotate the turntable (120) based on the calculated rotation speed.
[0067] According to the example described above, the cooking device (100) can adjust the rotation speed of the turntable (120) so that, considering the arrangement of the cooking container, the user can easily remove the cooking container from the cooking device (100) after the cooking operation is completed. Accordingly, user convenience can be improved.
[0068] FIG. 3 is a flowchart illustrating the operation method of a cooking device according to one embodiment.
[0069] According to FIG. 3, according to one embodiment, the operation method may include an operation (S310) of identifying the placement state of a cooking vessel on a rotating plate included in a cooking device at the time of cooking start based on sensing data obtained through at least one sensor.
[0070] According to one example, the cooking device may acquire sensing data through at least one sensor. According to one example, the cooking device may identify the arrangement state of a cooking vessel on a rotating plate included in the cooking device based on the acquired sensing data. According to one example, the cooking device may identify the arrangement state of the cooking vessel at the start of cooking when user input for cooking food is received after the cooking vessel is inserted into the cooking chamber.
[0071] According to one embodiment, the method of operation may include an operation (S320) of calculating a rotational speed for the cooking container to be placed in the first placement direction at the time of completion of cooking, when a first placement direction is identified that makes it easy to remove the cooking container based on the identified placement state.
[0072] According to one example, when the cooking device identifies the placement state of the cooking vessel at the start of cooking, it can identify a first placement direction based on the identified placement state. For example, the first placement direction may be a direction in which the handle of the cooking vessel faces the door. According to one example, when the first placement direction is identified, the cooking device can calculate a rotational speed for the cooking vessel to be placed in the first placement direction at the time of completion of cooking, based on the identified placement state and the identified first placement direction. For example, the rotational speed may identify a rotational speed among at least one rotational speed at which the cooking vessel is placed in the first placement direction at the time of completion of cooking, such that the error with the rotational speed corresponding to the basic operation mode is minimized.
[0073] According to one embodiment, the operation method may include an operation (S330) of controlling a turntable based on a calculated rotational speed.
[0074] According to one example, when a rotational speed is calculated for a cooking vessel to be positioned in a first positioning direction at the time of completion of cooking, the cooking device can control a turntable based on the calculated rotational speed. For example, the cooking device can control a drive unit to rotate the turntable based on the calculated rotational speed.
[0075] FIG. 4 is a flowchart illustrating a method for controlling a rotating plate to rotate at different rotational speeds according to one embodiment.
[0076] According to FIG. 4, according to one embodiment, the operation method may include an operation (S410) of controlling the turntable to rotate at a first rotational speed for a first time from the time of cooking start.
[0077] According to one example, when a user input for performing a cooking operation is received, the cooking device may control the turntable so that the turntable rotates at a first rotational speed for a first time period from the start of cooking. According to one example, the first time period may be the time from the start of cooking until a time period prior to a preset time (e.g., 3 seconds) prior to the completion of cooking. For example, the first time period may mean the time from the start of cooking until 3 seconds prior to the completion of cooking.
[0078] According to one example, the cooking device may control the turntable to rotate at a first rotational speed corresponding to a basic operation mode during a first time period. However, it is not limited thereto, and the first rotational speed may vary based on user input. For example, when user input is received to operate in an operation mode other than the basic operation mode (e.g., an operation mode corresponding to a specific food type), the cooking device may control the drive unit to rotate the turntable at a rotational speed corresponding to the identified operation mode based on the received user input.
[0079] According to one embodiment, the operation method may include an operation (S420) of controlling the turntable to rotate at a second rotational speed during a second time from the time when the first time has elapsed until the time when cooking is completed.
[0080] According to one example, the cooking device may control the drive unit so that the turntable rotates at a second rotational speed for a second time after a first time has elapsed from the time cooking begins. According to one example, the second time may be a preset time (e.g., 3 seconds) from the time cooking is completed.
[0081] According to one example, the second rotational speed may be a rotational speed for the cooking vessel to be positioned in a first positioning direction. According to one example, the second rotational speed may be a rotational speed calculated based on the first positioning direction and a second time. For example, the cooking device may identify the rotational speed for the cooking vessel to be positioned in the first positioning direction as the second rotational speed after performing an operation corresponding to the first rotational speed during a first time.
[0082] According to one example, the cooking device may identify a second rotational speed based on the arrangement direction of the cooking vessel at a point in time after a first time has elapsed. For example, the cooking device may identify the arrangement direction of the cooking vessel at a point in time after a first time has elapsed based on sensing data obtained through at least one sensor, and identify a first amount of rotation for the cooking vessel to be arranged in the first arrangement direction based on the identified arrangement direction. The cooking device may calculate a second rotational speed based on the identified first amount of rotation.
[0083] Alternatively, according to one example, the cooking device may identify a second rotation speed based on the amount of rotation of the turntable at the first time. This will be explained through FIG. 5.
[0084] FIG. 5 is a flowchart illustrating a method for calculating a second rotational speed according to one embodiment.
[0085] According to FIG. 5, according to one embodiment, the operation method may include an operation (S510) of calculating a second rotation amount for the cooking vessel to be placed in a first placement direction based on a first rotation amount during a first time.
[0086] According to one example, the cooking device can calculate a first amount of rotation of the turntable during a first time period. According to one example, if the first amount of rotation is calculated based on the first rotation speed of the turntable during the first time period, the cooking device can calculate a second amount of rotation corresponding to the amount of rotation of the turntable during a second time period. For example, the cooking device can calculate an amount of rotation (or total amount of rotation) for the cooking vessel to be positioned in a first positioning direction at the time of cooking completion, based on the positioning state of the cooking vessel at the time of cooking start. According to one example, the cooking device can calculate the amount of rotation that minimizes the error with the amount of rotation corresponding to the basic operation mode (or the amount of rotation corresponding to the basic operation mode during the cooking time) as the total amount of rotation. Based on the total amount of rotation and the first amount of rotation, the cooking device can calculate a second amount of rotation corresponding to the second time period.
[0087] According to one embodiment, the operation method may include an operation (S520) of calculating a second rotational speed based on a calculated second rotational amount and a second time.
[0088] According to one example, when a second rotation amount is calculated based on a total rotation amount and a first rotation amount, the cooking device can calculate a second rotation speed such that the rotation amount of the turntable during the second time becomes the second rotation amount. According to one example, the cooking device can control a drive unit so that the turntable rotates during the second time at the calculated second rotation speed.
[0089] FIG. 6 is a flowchart illustrating a method for controlling a rotating plate to rotate at a third rotational speed according to one embodiment.
[0090] According to FIG. 6, according to one embodiment, the operation method may include an operation (S610) of calculating a third rotation speed for the cooking container to be positioned in a first positioning direction at the time of completion of cooking based on the cooking time when a user input for setting the cooking time of the cooking device is received.
[0091] According to one example, the cooking device may receive user input related to the cooking time for performing a cooking operation. According to one example, when the cooking device receives user input corresponding to the cooking time, it may calculate a third rotational speed for the cooking container to be positioned in a first positioning direction at the time of cooking completion. According to one example, the third rotational speed may be the rotational speed of the turntable from the time of cooking start to the time of cooking completion. According to one example, unlike as disclosed in FIGS. 4 and 5, the cooking device may rotate the turntable without changing the rotational speed while the food is being cooked.
[0092] According to one example, the cooking device can calculate a third rotational speed for positioning the cooking vessel in a first positioning direction based on the cooking time. According to one example, the rotational speed at which the cooking vessel is positioned in the first positioning direction at the time of completion of cooking may have multiple values depending on the amount of rotation.
[0093] For example, it can be assumed that 0.6 rotations are required for the cooking vessel to be placed in the first placement direction. Even when an integer number of rotations is added to the aforementioned 0.6 rotations (e.g., 1.6, 2.6, or 3.6, etc.), the cooking vessel can be placed in the first placement direction. Accordingly, a plurality of values corresponding to each rotation amount can be calculated for the rotation speed corresponding to the first placement direction. Among the plurality of calculated values, the cooking device can calculate the rotation speed that minimizes the error with the rotation speed corresponding to the basic operation mode as the third rotation speed.
[0094] However, this is not limited thereto, and according to one example, the cooking device may calculate a third rotational speed at which the error with the rotational speed corresponding to the specific operation mode is minimized, based on user input for the cooking device to operate in a specific operation mode (e.g., an operation mode corresponding to a specific type of food).
[0095] According to one embodiment, the operation method may include an operation (S620) of controlling the turntable to rotate at a calculated third rotational speed from the time of cooking start to the time of cooking completion.
[0096] According to one example, the cooking device can control the drive unit so that the rotating plate rotates at a calculated third rotational speed during the cooking time (or, the time from the start of cooking to the completion of cooking).
[0097] FIG. 7 is a flowchart illustrating a method for changing the time a turntable rotates according to one embodiment.
[0098] According to FIG. 7, according to one embodiment, the operation method may include an operation (S710) of identifying a third time during which the rotating plate rotates based on a first rotational speed corresponding to a basic operation mode and an identified first arrangement direction.
[0099] According to one example, when a first placement direction is identified based on sensing data acquired through at least one sensor, the cooking device can identify an amount of rotation for a cooking vessel to be placed in the first placement direction based on the identified first placement direction.
[0100] According to one example, when there are multiple values for the amount of rotation for being arranged in a first arrangement direction, the cooking device can calculate the time required for each of the multiple values when the rotating plate rotates at a first rotation speed.
[0101] For example, it may be assumed that 0.6 rotations are required for the cooking vessel to be placed in the first placement direction. The amount of rotation required for the cooking vessel to be placed in the first placement direction may be a plurality of values, including cases where an integer number of rotations is added to the aforementioned 0.6 rotations (e.g., 1.6, 2.6, or 3.6, etc.). According to one example, the cooking device may calculate the time required for the turntable to rotate at the first rotation speed for each of the aforementioned plurality of values.
[0102] According to one example, when the cooking device calculates the time required when the turntable rotates at a first rotational speed, it can identify the time with the minimum error from the cooking time entered by the user as the third time among the calculated times. According to one example, the third time may differ from the cooking time entered by the user, and according to one example, the third time may be a smaller value than the cooking time entered by the user.
[0103] However, this is not limited thereto, and it goes without saying that, depending on one example, the cooking device may also identify a third time based on a rotational speed corresponding to a specific operating mode (e.g., an operating mode corresponding to a specific type of food).
[0104] According to one embodiment, the operation method may include an operation (S720) of controlling the turntable to rotate at a first rotational speed for a third time period from the start of cooking. According to one example, the cooking device may control the drive unit to rotate the turntable at a first rotational speed for a third time period from the start of cooking.
[0105] According to one embodiment, the operation method may include an operation (S730) of controlling the turntable to stop during a fourth time period from the time when the third time has elapsed until the time when cooking is completed. According to one example, when the time when the third time has elapsed from the time when cooking starts is reached, the cooking device may control the drive unit so that the turntable no longer rotates during the fourth time period until the time when cooking is completed. According to one example, the cooking operation may still be performed during the fourth time period from the time when the third time has elapsed until the time when cooking is completed.
[0106] According to the example described above, the cooking device identifies the time during which the turntable rotates to position the cooking vessel in a first placement direction, and by rotating the turntable during the identified time, the cooking vessel can be positioned in the first placement direction at the time of cooking completion. In this case, even if the turntable is stopped, the cooking operation is continuously performed until the time of cooking completion, and accordingly, the user can easily remove the cooking vessel from the cooking device without any degradation in cooking performance.
[0107] FIG. 8 is a flowchart illustrating a method of operation of a cooking device when the cooking time of the cooking device is changed while performing a cooking operation according to one embodiment.
[0108] According to FIG. 8, according to one embodiment, the operation method may include an operation (S810) of updating the cooking completion time based on the received user input when a user input to change the cooking time of the cooking device is received while performing a cooking operation.
[0109] According to one example, while a cooking device is performing a cooking operation on food at a first rotational speed, it may receive user input to change the cooking time of the cooking device. For example, while a cooking device is performing a cooking operation based on user input to perform a cooking operation for a first cooking time, it may receive user input to perform a cooking operation for a second cooking time different from the first cooking time.
[0110] According to one example, when a cooking device receives user input to change the cooking time, it can update the cooking completion time based on the received user input. For example, the cooking device can identify a cooking completion time corresponding to a second cooking time.
[0111] According to one embodiment, the operation method may include an operation (S820) of calculating a fourth rotation speed for the cooking container to be positioned in a first placement direction at the time of updated cooking completion.
[0112] According to one example, the cooking device may calculate a fourth rotation speed based on the second cooking time when the cooking time is updated to a second cooking time. According to one example, the amount of rotation (or the amount of rotation of the turntable (120) during the cooking time) for the cooking vessel to be placed in the first placement direction at the time of completion of cooking may be a plurality of values (e.g., 0.6 times, 1.6 times, and 2.6 times, etc.) regardless of the cooking time. According to one example, the cooking device may calculate at least one rotation speed based on each amount of rotation and the second cooking time.
[0113] According to one example, the cooking device may calculate a fourth rotational speed among at least one calculated rotational speed such that the error with the rotational speed corresponding to the basic operation mode is minimized. However, it is not limited thereto, and according to one example, the cooking device may calculate a fourth rotational speed such that the error with the rotational speed corresponding to a specific operation mode is minimized.
[0114] According to the example described above, the cooking device may change the rotation speed so that the cooking container is positioned in the first placement direction at the time of completion of cooking when a user input changing the cooking time is changed during the cooking operation. Accordingly, even when food is cooked with the changed cooking time, the user can easily remove the cooking container when cooking is completed.
[0115] Returning to FIG. 2, according to one embodiment, the processor (130) can update the first placement direction. According to one example, if contamination of the cooking container is identified during a cooking operation based on acquired sensing data, the processor (130) can update the first placement direction based on the location of contamination within the cooking container and the placement state. For example, the processor (130) can continuously monitor the cooking container even during a cooking operation. Based on acquired sensing data, the processor (130) can identify contamination of the cooking container caused by food within the cooking container during a cooking operation. According to one example, if contamination of the cooking container is identified, the processor (130) can update the placement direction to the first placement direction in which a second part of the cooking container that is not contaminated is placed toward the door.
[0116] According to one example, the processor (130) can identify a rotational speed for the cooking vessel to be placed in an updated first placement direction at the time of completion of cooking. According to one example, when the first placement direction is updated, the processor (130) can identify a fifth rotational speed for the cooking vessel to be placed in an updated first placement direction at the time of completion of cooking, based on a fifth time from the time of update to the time of completion of cooking. For example, the amount of rotation for the cooking vessel to be placed in an updated first placement direction at the time of completion of cooking (or the amount of rotation of the turntable (120) during the cooking time) may be a plurality of values (e.g., 0.8 times, 1.8 times, and 2.8 times, etc.), and a rotational speed corresponding to each amount of rotation may be calculated. The processor (130) can identify a rotational speed corresponding to each amount of rotation based on the fifth time, and among the identified rotational speeds, identify a rotational speed that has the minimum error with the first rotational speed corresponding to the basic operation mode as the fifth rotational speed. According to one example, the processor (130) can control the drive unit so that the rotating plate (120) rotates at a fifth rotational speed during the fifth time.
[0117] FIG. 9 is a flowchart illustrating a method for identifying a first arrangement direction according to one embodiment.
[0118] According to FIG. 9, according to one embodiment, the operation method may include an operation (S910) of identifying a first part with a relatively low temperature within the cooking container based on sensing data obtained through a thermal imaging camera included in at least one sensor when it is identified that the handle of the cooking container is not present.
[0119] According to one example, the cooking device can identify whether a handle is present in a cooking container inserted into the cooking device. For example, the cooking device can identify whether the cooking container includes a handle based on sensing data acquired through at least one sensor.
[0120] According to one example, at least one sensor may include a thermal imaging camera. According to one example, if the cooking device identifies that the handle of the cooking vessel is not present, it may identify a first portion within the cooking vessel that has a relatively low temperature based on sensing data acquired through the thermal imaging camera. For example, if the cooking device acquires a thermal image corresponding to the cooking vessel through the thermal imaging camera, it may identify a pixel region with a relatively low temperature among the acquired image. The cooking device may identify a first portion within the cooking vessel corresponding to the identified pixel region.
[0121] However, this is not limited thereto, and according to one example, the cooking device may identify a first part within the cooking container based on sensing data obtained through a thermal imaging camera even when the cooking container does not have directionality.
[0122] According to one embodiment, the operation method may include an operation (S920) of identifying a first placement direction based on the position and placement state of the identified first part within the cooking container.
[0123] According to one example, when a first part is identified, the cooking device can identify a first placement direction based on the position and arrangement state of the identified first part within the cooking container. For example, the cooking device can identify a first placement direction as a first placement direction for the first part to be placed at a preset position (e.g., a position where the first part faces the door) based on the current arrangement state of the cooking container.
[0124] According to one example, the cooking device can identify an amount of rotation for the cooking vessel to be positioned in the first positioning direction at the time of completion of cooking, based on the identified first positioning direction. According to one example, the cooking device can calculate the rotation speed of the turntable based on the identified amount of rotation and the cooking time.
[0125] FIG. 10 is a flowchart illustrating the operation of controlling a rotating plate according to one embodiment.
[0126] According to FIG. 10, according to one embodiment, the operation method may include an operation (S1010) of identifying whether the door is opened when a cooking operation stop event occurs during the cooking operation.
[0127] According to one example, the cooking device can identify whether a cooking operation stop event occurs during a cooking operation. According to one example, the cooking device may include a door. According to one example, the cooking operation stop event may include a user input corresponding to a cooking operation stop or a user input corresponding to a cooking operation end, but is not limited thereto. Alternatively, according to one example, the cooking operation stop event may include an event in which the door is opened. According to one example, the cooking device can identify whether the door is opened when a cooking operation stop event occurs.
[0128] According to one embodiment, the operation method may include an operation (S1020) of controlling a turntable so that a cooking vessel is positioned in an identified first positioning direction when it is identified that the door is not open.
[0129] According to one example, when a cooking device detects that a cooking operation stop event has occurred and that the door is not open, it may control a turntable so that a cooking vessel is placed in an identified first placement direction. In this case, no separate cooking operation may be performed, and only the rotation of the turntable may be performed. The cooking device may control a drive unit so that the turntable rotates with a minimum amount of rotation required for the cooking vessel to be placed in the first placement direction. In this case, the cooking device may control the door so that it does not open for a preset time, even when a user's door opening input is received. According to one example, the preset time may be the time required for the turntable to rotate with a minimum amount of rotation.
[0130] According to the example described above, even if a sudden cooking operation stop event occurs, the cooking device can rotate the turntable with a minimum amount of rotation to position the cooking container in the first placement direction, provided the door is not open. Accordingly, the user can easily take out the cooking container.
[0131] Alternatively, according to one example, the cooking device may control the drive unit to rotate the turntable when a user's body part is not identified within the cooking chamber even when a cooking operation stop event occurs and the door is opened. For example, the cooking device may determine whether a user's body part (e.g., a hand) is identified within the cooking chamber based on sensing data obtained through at least one sensor when a cooking operation stop event occurs and the door is open. If a user's body part is not identified within the cooking chamber for a preset time, the cooking device may rotate the turntable by a minimum amount of rotation to position the cooking container in a first placement direction.
[0132] FIGS. 11a and FIGS. 11b are drawings for explaining the operation of a cooking device according to one embodiment.
[0133] According to FIG. 11a, according to one embodiment, a cooking device (1100) can identify the placement state of a cooking container (1101) at the time of cooking start. According to one example, as shown in the left drawing (1110) of FIG. 11a, when a cooking container (1101) is inserted into the cooking device (1100), the cooking device (1100) can identify the placement state of the cooking container (1101) based on sensing data obtained through at least one sensor. According to one example, if the cooking container (1101) is implemented as a cup including a handle, the cooking device (1100) can identify the placement state including the direction of the handle.
[0134] According to one example, the cooking device (1100) can identify a first placement direction that facilitates the removal of the cooking container (1101) based on the identified placement state. According to one example, the cooking device (1100) can calculate a rotational speed for the cooking container (1101) to be placed in the identified first placement direction at the time of completion of cooking. For example, as shown in the left drawing (1110) of FIG. 11a, if the handle is located in the direction of the door, the first placement direction that facilitates the removal of the cooking container (1101) may be the same as the placement state of the cooking container (1101) at the time of start of cooking. In this case, the amount of rotation of the turntable can be identified as an integer. The cooking device (1100) can identify a rotational speed based on the identified amount of rotation.
[0135] According to one example, the cooking device (1100) can perform a cooking operation when user input for performing a cooking operation is received. According to one example, the cooking device (1100) can perform a cooking operation by rotating a turntable at a calculated rotational speed. According to one example, the cooking device (1100) can terminate the cooking operation when it reaches the point of completion of cooking. According to one example, when it reaches the point of completion of cooking, the cooking container (1101) may be in a position that is easy for the user to take out, as shown in the right drawing (1120) of FIG. 11a.
[0136] According to FIG. 11b, according to one embodiment, the cooking device (1100) can identify the arrangement state of the cooking container (1101) at the time of cooking start. According to one example, the cooking device (1100) can identify the arrangement state of the cooking container (1101) at the time of cooking start based on a preset image analysis algorithm. For example, the cooking device (1100) may include a camera sensor for acquiring an image of the cooking chamber. The cooking device (1100) can identify the arrangement state of the cooking container (1101), including the position of the handle at the time of cooking start, by inputting the sensing data acquired through the camera sensor into a preset image analysis algorithm.
[0137] According to one example, the pre-set image analysis algorithm may be implemented as a different type of algorithm that extracts the shape of an object included in the image and identifies the relative position of a handle included in the cooking container (1101). The cooking device (1100) can identify the arrangement state of the cooking container (1101) using the pre-set image analysis algorithm.
[0138] According to one example, the cooking device (1100) can identify a first placement direction based on the placement state. According to one example, as illustrated in the left drawing (1130) of FIG. 11b, if the handle is not located in the door-side direction, the first placement direction that makes it easy to remove the cooking container (1101) may differ from the placement state of the cooking container (1101) at the start of cooking. For example, the first placement direction may be a placement direction in which the handle is located in the door-side direction. According to one example, when the first placement direction is identified, the cooking device (1100) can calculate a rotation speed for the cooking container (1101) to be placed in the identified first placement direction at the time of completion of cooking. For example, the cooking device (1100) can identify the position of the handle based on the placement state of the cooking container (1101) at the start of cooking, and when the first placement direction corresponding to the position of the handle at the time of completion of cooking is identified, it can calculate a rotation speed based thereon.
[0139] According to one example, the cooking device (1100) can perform a cooking operation by rotating a turntable at a calculated rotational speed. According to one example, the cooking device (1100) can terminate the cooking operation when it reaches the point of completion of cooking. According to one example, when it reaches the point of completion of cooking, the cooking container (1101) may be in a position that is easy for the user to take out, as shown in the right drawing (1140) of FIG. 11b.

[0141] According to FIG. 12, the cooking device (100') may include at least one sensor (110), a turntable (120), at least one processor (130), a memory (140), a door (150, e.g., the door (80) of FIG. 1a to 1c), a user interface (160), a communication interface (170), a speaker (180), a microphone (190), and a driving unit (195, e.g., the turntable motor (33) of FIG. 1a to 1c). A detailed description of configurations shown in FIG. 12 that overlap with configurations shown in FIG. 1a to 1c and FIG. 2 will be omitted.
[0142] The user interface (160) is configured for the cooking device (100') to perform interaction with the user. For example, the user interface (160) may include at least one of a touch sensor, a motion sensor, a button, a jog dial, a switch, a microphone, or a speaker, but is not limited thereto.
[0143] The communication interface (170) can input and output various types of data. For example, the communication interface (170) can transmit and receive various types of data to and from an external device (e.g., source device), an external storage medium (e.g., USB memory), an external server (e.g., web hard drive) through communication methods such as AP-based Wi-Fi (Wi-Fi, Wireless LAN network), Bluetooth, Zigbee, wired / wireless LAN (Local Area Network), WAN (Wide Area Network), Ethernet, IEEE 1394, HDMI (High-Definition Multimedia Interface), USB (Universal Serial Bus), MHL (Mobile High-Definition Link), AES / EBU (Audio Engineering Society / European Broadcasting Union), Optical, Coaxial, etc.
[0144] According to one example, the communication interface (170) may include a Bluetooth Low Energy (BLE) module. BLE refers to Bluetooth technology capable of transmitting and receiving low-power, low-capacity data in a 2.4 GHz frequency band with a range of about 10 m. However, it is not limited thereto, and the communication interface (170) may include a Wi-Fi communication module. That is, the communication interface (170) may include at least one of a Bluetooth Low Energy (BLE) module or a Wi-Fi communication module.

[0147] According to one embodiment, the speaker (180) can output an acoustic signal to the outside of the cooking device (100'). The speaker (180) can output multimedia playback, recording playback, various notification sounds, voice messages, etc. The cooking device (100') may include an audio output device such as the speaker (180), but may include an output device such as an audio output terminal. In particular, the speaker (180) can provide acquired information, information processed or produced based on the acquired information, response results to user voice or operation results, etc., in the form of voice.
[0148] The microphone (190) may refer to a module that acquires sound and converts it into an electrical signal, and may be a condenser microphone, ribbon microphone, moving coil microphone, piezoelectric element microphone, carbon microphone, or MEMS (Micro Electro Mechanical System) microphone. Additionally, it may be implemented in omnidirectional, bidirectional, unidirectional, subcardioid, supercardioid, or hypercardioid modes. According to one embodiment, the cooking device (100') may include a microphone (190) and an inner microphone, and the microphone (190) may be a microphone located relatively outside the body. According to one example, the cooking device (100') may acquire an audio signal including external noise through the microphone (190). According to one embodiment, the microphone (190) may be positioned in a direction opposite to the direction in which the speaker (180) emits sound.
[0149] According to the example described above, the cooking device (100') can adjust the rotation speed of the turntable (120) so that, considering the arrangement of the cooking container, the user can easily remove the cooking container from the cooking device (100') after the cooking operation is completed. Accordingly, user convenience can be improved.
