The cooker identification unit identifies the cook based on the information about the cook. The operation instruction judgment unit judges whether an operation instruction acquired by the operation instruction acquisition unit while cooking is being performed in the cooking system is an operation instruction by the cook based on the result of the identification by the cooker identification unit. The execution control unit controls the execution of an operation on the kitchen ventilation device based on the operation instruction acquired by the operation instruction acquisition unit. When the operation instruction judgment unit determines that the operation instruction is an operation instruction by a cook, the execution control unit executes an operation on the kitchen ventilation device based on the operation instruction, but when the operation instruction judgment unit determines that the operation instruction is not an operation instruction by a cook, the execution control unit does not execute an operation on the kitchen ventilation device based on the operation instruction.

[0007] A cooking device of the present invention for achieving the above object is a cooking device of a cooking system including a kitchen ventilation device and a cooking device. The cooking device has an operation instruction acquisition unit, a cooking judgment unit, a cooker information acquisition unit, a cooker identification unit, an operation instruction judgment unit, and an execution control unit. The operation instruction acquisition unit acquires operation instructions for the cooking device from outside the cooking system. The cooking judgment unit judges whether cooking is being performed in the cooking system. The cooker information acquisition unit acquires information about a cook of the cooking system. The cooker identification unit identifies the cook based on the information about the cook. The operation instruction judgment unit judges whether an operation instruction acquired by the operation instruction acquisition unit while cooking is being performed in the cooking system is an operation instruction by the cook based on the result of the identification by the cooker identification unit. The execution control unit controls the execution of an operation on the cooking device based on the operation instruction acquired by the operation instruction acquisition unit. When the operation instruction judgment unit determines that the operation instruction is an operation instruction by a cooker, the execution control unit executes an operation on the heating cooker based on the operation instruction, but when the operation instruction judgment unit determines that the operation instruction is not an operation instruction by a cooker, the execution control unit does not execute an operation on the heating cooker based on the operation instruction.

[0008] In order to achieve the above-mentioned object, the cooking system control method of the present invention is a control method for a cooking system having at least one of a kitchen ventilation device and a cooking appliance as an externally operated device, the control method including: an acquisition step of acquiring operation instructions for the operation target device from outside the cooking system; a determination step of judging whether cooking is being performed in the cooking system; a cooker information acquisition step of acquiring information about a cook of the cooking system; an identification step of identifying the cook based on the information about the cook; a determination step of judging whether an operation instruction acquired in the acquisition step while cooking is being performed in the cooking system is an operation instruction by the cook based on a result of the identification in the identification step; and an execution control step of controlling execution of an operation on the operation target device based on the operation instruction acquired in the acquisition step, in which if it is determined in the execution control step that the operation instruction is an operation instruction by the cook, an operation is executed on the operation target device based on the operation instruction, whereas if it is determined that the operation instruction is not an operation instruction by the cook, the operation on the operation target device based on the operation instruction is not executed. Effect of the Invention

[0009] According to the cooking system, kitchen ventilation device, cooking appliance, and cooking system control method of the present invention, when an operation instruction from outside the cooking system is determined to be an operation instruction from a cook, an operation is performed on the operation target device based on the operation instruction. On the other hand, when an operation instruction from outside the cooking system is determined to not be an operation instruction from a cook, an operation is not performed on the operation target device based on the operation instruction. Therefore, during cooking, remote operation of the operation target device by a cook is enabled, while remote operation by anyone other than the cook is prevented or suppressed. As a result, execution of operations unintended by the cook can be prevented or suppressed. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiment. Note that the drawings are exaggerated for the convenience of explanation. Therefore, the dimensional ratios of each component in each drawing may differ from the actual ones. In addition, the same elements in the drawings are given the same reference numerals, and duplicated explanations in the specification are omitted.

[0012] (Cooking system configuration) Fig. 1 is a front view of the cooking system according to the present embodiment when installed in a kitchen, and Fig. 2 is a right side cross-sectional view (or side view) of the cooking system according to the present embodiment when installed in a kitchen.

[0013] As shown in Figures 1 and 2, a cooking system 400 of this embodiment has a range hood 100 and a cooking appliance 200 as kitchen ventilation devices. The cooking system 400 constitutes a cooking guide system. The range hood 100 is installed above the cooking appliance 200. The range hood 100 sucks in odors and oily smoke, including odors, smoke, and oil, generated during cooking with the cooking appliance 200, and exhausts them to the outside.

[0014] In this embodiment, the cook can use the external terminal 700 to remotely control the operation target device from outside the cooking system 400. The cooking system 400 acquires an operation instruction from the external terminal 700 and executes an operation on the operation target device based on the operation instruction. Meanwhile, a person other than the cook (e.g., the cook's family or friend) also has an external terminal 700 that can remotely control the operation target device of the cooking system 400, but the cooking system 400 does not execute an operation on the operation target device based on an operation instruction from outside by a person other than the cook. In other words, the cooking system 400 refuses to operate the operation target device based on an operation instruction from outside the cooking system 400 by a person other than the cook.

[0015] 1 and 2 has three heat sources 210 (a collective term for three heat sources 210A, 210B, and 210C described below) and a grill outlet 220. In this specification, the heat source means a burner or a trivet near the burner for a gas cooker, and a heater for an IH cooker.

[0016] Cooking device 200 also includes a weight sensor that detects the weight of a cooking utensil (including food to be cooked in the cooking utensil) such as a pot placed on the top surface of the trivet or heater, and a first temperature sensor that detects the temperature of the cooking utensil (for example, the temperature of the bottom of the pot) (both not shown). The first temperature sensor may be, for example, a contact-type temperature sensor. Cooking device 200 also includes operation unit 240 that includes an ignition switch for operating heat source 210, a heat adjustment knob, a display unit, and the like. The display unit displays, for example, the strength of heat for each of heat sources 210A to 210C. The first temperature sensor, weight sensor, and heat source 210 are controlled by control unit 230. Control unit 230 is composed of a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and the like, which are not shown.

[0017] The range hood 100 includes a fan 116 , a fan motor 117 , a filter 118 , a filter motor 119 , an operation panel 120 , a control unit 130 , and a second temperature sensor 300 .

[0018] The range hood 100 has a second temperature sensor 300 that detects the temperature above the cooking device 200 on the underside of the front side to the left of the center. The second temperature sensor 300 detects the temperature of the area shown by the dotted line in the figure. The second temperature sensor 300 used in this embodiment is a compound temperature sensor that has, for example, 64 pixels (8 x 8) and can separately detect the temperature of the area corresponding to each pixel. The second temperature sensor 300 can detect the temperature above the cooking device 200 by dividing it into 64 areas, and can also detect the temperature of each of the three heat sources and the temperature of the grill outlet 220 separately.

[0019] In this embodiment, a compound temperature sensor is used as the second temperature sensor 300, but a single temperature sensor may be used. When using a single temperature sensor, one single temperature sensor capable of detecting the temperature above the cooking device 200 as a whole may be provided on the underside of the range hood 100. In that case, it is preferable to provide four single temperature sensors corresponding to the three heat sources and the grill outlet so that the temperatures of each of the three heat sources and the grill outlet can be detected individually. When actually installing, a compound temperature sensor is preferable to a single temperature sensor. This is because the detection accuracy of a compound temperature sensor is better than that of a single temperature sensor. When using a compound temperature sensor, it is not limited to the compound temperature sensor having 64 pixels of 8×8 as illustrated, but a compound temperature sensor having more pixels may be used.

[0020] The range hood 100 is provided with a blower box 110 at its upper portion. The blower box 110 exhausts odors and oily smoke from the cooking appliance 200. The blower box 110 is provided with an intake port 112 for sucking in oily smoke from the cooking appliance 200, an exhaust port 114 communicating with the outdoors, and a fan 116 for exhausting the oily smoke sucked from the intake port 112 into a passage connecting the intake port 112 and the exhaust port 114. The fan 116 is driven by a fan motor 117. Between the intake port 112 and the fan 116, a filter 118 is provided that rotates to remove oil from the oily smoke sucked from the intake port 112. The filter 118 is driven by a filter motor 119. When the fan 116 is rotating, the filter 118 also rotates. The range hood 100 may be provided with a fixed filter that does not rotate, or may be a filterless range hood. The range hood 100 is provided with an operation panel 120 on the front side for instructing the operation of the range hood 100.

[0021] 3 is a front view of an operation panel 120 provided in the range hood 100 of this embodiment. The operation panel 120 includes an operation switch 121, a mode changeover switch 122, a timer switch 123, a constant ventilation switch 124, and a lighting switch 125.

[0022] The operation switch 121 is a switch for operating the range hood 100. When the operation switch 121 is pressed, an operation start signal is sent to the control unit 130, and when pressed again, a normal operation end signal is sent. In the case of this embodiment, when the operation switch 121 is pressed, operation is started in the operation mode in which operation was stopped the previous time.

[0023] The mode changeover switch 122 is a switch for changing the air volume of the fan 116 and / or the rotation speed of the filter 118 among a manual mode (low, medium, high), an auto mode, and a grill mode.

[0024] The timer switch 123 is a switch for performing a timer operation that rotates the fan 116 and / or the filter 118 for a set time. When the timer switch 123 is pressed, a normal operation end signal is sent to the control unit 130, and the timer operation set for each operation mode is performed.

[0025] The timer time in the manual mode can be set to T1, T2, T3, or any other desired timer time by operating the timer switch 123. The timer time in the auto mode can also be set to any desired time by the timer switch 123.

[0026] The constant ventilation switch 124 is a switch for starting / stopping the constant ventilation by rotating / stopping the fan 116 and / or the filter 118.

[0027] The lighting switch 125 is a switch for turning on / off an LED light bulb (lighting device) that illuminates the upper surface of the cooking device 200.

[0028] 4 is a diagram showing a schematic state of detection of the temperature above the cooking appliance 200 by the second temperature sensor 300. As described above, the second temperature sensor 300 is attached to the underside of the range hood 100. The temperature above the cooking appliance 200 is detected in an area covering the heat sources (burners and trivets or heaters near the burners) 210A, 210B, 210C of the cooking appliance 200 and the grill air outlet 220.

[0029] In this embodiment, a compound temperature sensor having pixels (Tij (i = 1 to 8, j = 1 to 8)) divided into, for example, 64 of 8 × 8 is used. Therefore, the temperatures of the heat sources 210A, 210B, 210C and the grill outlet 220 of the cooking device 200 are detected as the maximum temperatures of the regions of the divided pixels corresponding to the heat sources 210A, 210B, 210C and the grill outlet 220, respectively, as shown in FIG. 4. On the other hand, when the second temperature sensor 300 is a monocular temperature sensor, four monocular temperature sensors are provided corresponding to the heat sources 210A, 210B, 210C and the grill outlet 220 of the cooking device 200, respectively. Therefore, the temperature above the cooking device 200 is detected for each of the heat sources 210A, 210B, 210C and the grill outlet 220 of the cooking device 200.

[0030] The control unit 130 is composed of a CPU, RAM, ROM, etc. (not shown). The control unit 130 realizes various functions by the CPU executing a program loaded in the RAM. Specific functions of the control unit 130 will be described later.

[0031] The imaging unit (image sensor) 140 is installed in a position overlooking the cooking appliance 200 under the range hood 100, and captures an image of a predetermined shooting area including the upper surface of the cooking appliance 200. The images captured by the imaging unit 140 may include still images and moving images.

[0032] The human presence sensor 150 has a detection range including the room in which the cooking system 400 is installed, and detects a cook in the vicinity of the target device. The human presence sensor 150 may be of any type, such as infrared, ultrasonic, or visible light.

[0033] The microphone 160 is installed, for example, on the blower box 110, and collects sounds generated around the device to be operated, such as the sounds of cooking operations, sounds from cooking utensils, the sounds of opening and closing a refrigerator installed in the kitchen, the sounds of opening and closing a water tap, etc.

[0034] The wind speed sensor 170 is installed, for example, in the blower box 110 and measures the airflow (wind speed) in the blower box 110.

[0035] (Control system of cooking system 400) FIG. 5 is a functional block diagram illustrating the functions of the control system of the cooking system 400.

[0036] (Functions of control unit 130) The control unit 130 functions as a range hood communication unit 131, a range hood operation unit 132, a second temperature detection unit 133, an image detection unit 134, an airflow control unit 136, an illumination control unit 137, a range hood control unit 138, and a range hood storage unit 139. The second temperature detection unit 133 and the image detection unit 134 constitute a second cooking state detection unit 135. The second cooking state detection unit 135 detects the cooking state of the food. In this specification, the cooking state may be the total amount of heat applied to the food (ingredients) heated at n° C. for t minutes. The cooking state may also refer to any of the cooking history, such as whether the mixing operation was performed appropriately, the temperature at the end or start of the cooking process, or the cooking result, such as a change in color of the food.

[0037] The range hood communication unit 131 transmits and receives control signals and data to and from the cooking system control unit 500. The control signals include, for example, an instruction to start or stop blowing air by the fan 116, an instruction to start or stop rotation of the filter 118, an instruction to turn on / off a lighting device, and the like. The range hood communication unit 131 may also transmit and receive data related to the air volume of the fan 116 and / or the rotation speed of the filter 118. The instructions and data received by the range hood communication unit 131 are stored in the range hood storage unit 139.

[0038] Range hood operation unit 132 receives switching information from operation switch 121, mode changeover switch 122, timer switch 123, constant ventilation switch 124, and lighting switch 125 of operation panel 120. The switching information received by range hood operation unit 132 is stored in range hood storage unit 139.

[0039] The second temperature detection unit 133 controls the second temperature sensor 300 to perform detection at a predetermined second sampling interval, and receives the detection result from the second temperature sensor 300. The received detection result is stored in the range hood storage unit 139.

[0040] The image detection unit 134 receives an image captured by the imaging unit 140. The captured image (hereinafter also simply referred to as a "captured image") is stored in the range hood storage unit 139. The captured image may also be stored in another storage unit or may be directly transmitted.

[0041] The air blowing control unit 136 controls the fan motor 117 of the fan 116 and / or the filter motor 119 of the filter 118 in accordance with instructions from the range hood control unit 138 .

[0042] The lighting control unit 137 controls the lighting devices according to instructions from the range hood control unit 138.

[0043] Range hood control unit 138 comprehensively controls each of range hood communication unit 131, range hood operation unit 132, second temperature detection unit 133, image detection unit 134, air supply control unit 136, and lighting control unit 137. Based on the switch state of constant ventilation switch 124 and the control signal and data received from the cooking system control unit 500, range hood control unit 138 outputs instructions to air supply control unit 136 regarding the rotation of fan 116 and / or filter 118.

[0044] (Functions of the control unit 230) The control unit 230 functions as a cooking device communication unit 231, a cooking device operation unit 232, a first temperature detection unit 233, a weight detection unit 234, a heating control unit 236, a cooking device control unit 237, and a cooking device memory unit 238. The first temperature detection unit 233 and the weight detection unit 234 configure a first cooking state detection unit 235.

[0045] The cooking device communication unit 231 transmits and receives control signals and data to and from the cooking system control unit 500. The control signals include, for example, instructions to start or end heating by the heat source 210. The cooking device communication unit 231 can also transmit and receive data related to the heating power of the heat source 210. The instructions and data received by the cooking device communication unit 231 are stored in the cooking device storage unit 238.

[0046] Cooking device operation unit 232 receives input information from an ignition switch, a heat adjustment knob, etc. of operation unit 240 (see FIG. 1) of cooking device 200. The input information received by cooking device operation unit 232 is stored in cooking device memory unit 238.

[0047] The first temperature detection unit 233 controls the first temperature sensor to perform detection at a predetermined first sampling interval, and receives the detection result from the first temperature sensor. The received detection result is stored in the cooking device storage unit 238.

[0048] The weight detection unit 234 controls the weight sensor to perform detection at a predetermined third sampling interval, and receives the detection result from the weight sensor. The received detection result is stored in the cooking device storage unit 238.

[0049] The heating control unit 236 controls the heat source 210 according to instructions from the cooking device control unit 237 .

[0050] Cooking device control unit 237 comprehensively controls each of cooking device communication unit 231, cooking device operation unit 232, first temperature detection unit 233, weight detection unit 234, and heating control unit 236.

[0051] (Cooking system control unit 500) The cooking system control unit 500 is composed of a CPU, RAM, ROM, etc. (not shown). The cooking system control unit 500 realizes various functions by the CPU executing a control program loaded in the RAM.

[0052] The cooking system control unit 500 functions as an operation instruction acquisition unit 510, a cooking judgment unit 511, a cooker information acquisition unit 512, a cooker information memory unit 513, a cooker identification unit 514, a terminal information acquisition unit 515, a terminal information memory unit 516, an operation instruction judgment unit 517, an execution control unit 518, a cooking data acquisition unit 519, a cooking data memory unit 520, a cooking data execution unit 521, and an execution confirmation unit 522.

[0053] The operation instruction acquisition unit 510 acquires an operation instruction for the operation target device by receiving it from outside the cooking system 400. The operation target device from outside the cooking system 400 may be at least one of the range hood 100 and the cooking appliance 200. For example, the operation instruction acquisition unit 510 receives an operation instruction for the operation target device from an external terminal 700 outside the cooking system 400 through the cooking system communication unit 620. For example, if the operation target device is the range hood 100, the operation instruction may be to start the operation of the fan 116 and / or the filter 118, change the air volume, etc.

[0054] The cooking determination unit 511 determines whether cooking is being performed in the cooking system 400. The cooking determination unit 511 determines whether cooking is being performed in the cooking system 400, i.e., whether cooking is in progress, based on information such as the operation of the range hood, the operation of the cooking appliance, the presence or absence of food to be cooked, the presence or absence of cooking operations, and the presence or absence of people. In this embodiment, "cooking in progress" includes not only cooking operations, but also preparations such as washing and cutting ingredients by the cook, and intermediate operations. A specific method for determining whether cooking is in progress will be described later.

[0055] [How to determine whether the range hood 100 is working or not] Whether the range hood 100 is operating or not can be determined, for example, by whether an operation signal is output from the cooking system control unit 500 to the range hood 100 or not.

[0056] Furthermore, whether or not range hood 100 is operating can be determined based on whether or not a control signal is being output from range hood control unit 138 to lighting control unit 137 and air supply control unit 136. For example, when a control signal to turn on the illuminator is being output from range hood control unit 138 to lighting control unit 137, it is determined that range hood 100 is operating.

[0057] Furthermore, whether the range hood 100 is operating can be determined based on changes in the detection results (e.g., carbon monoxide or carbon dioxide concentrations, odor levels, temperature, humidity, etc.) of the air quality detection unit 610. For example, if the carbon monoxide or carbon dioxide concentrations, odor levels, temperature, or humidity around the cooking system 400 are decreasing, it is determined that the range hood 100 is operating.

[0058] Furthermore, whether or not the range hood 100 is operating can be determined based on the measurement results of the air speed sensor 170, ie, the airflow in the fan box 110 of the range hood 100.

[0059] In addition, whether or not the range hood 100 is operating can be determined based on a combination of at least two of the operation signal for the range hood 100, the control signals for the lighting control unit 137 and the air flow control unit 136, the detection result of the air quality detection unit 610, and the measurement result of the wind speed sensor 170.

[0060] [Method of determining whether cooking device 200 is operating] Whether or not the cooking appliance 200 is operating can be determined, for example, by whether or not an operation signal is output from the cooking system control unit 500 to the cooking appliance 200.

[0061] Furthermore, whether or not the cooking appliance 200 is operating can be determined based on whether or not a control signal is output from the cooking appliance control unit 237 to the heating control unit 236. For example, when a control signal to turn on the heat source 210 is output from the cooking appliance control unit 237 to the heating control unit 236, it is determined that the cooking appliance 200 is operating.

[0062] Furthermore, whether or not the cooking appliance 200 is operating can be determined based on changes in the detection results (e.g., carbon monoxide or carbon dioxide concentrations, odor levels, temperature, humidity, etc.) of the air quality detection unit 610. For example, when the carbon monoxide or carbon dioxide concentrations, odor levels, temperature, or humidity around the cooking system 400 are increasing, it is determined that the cooking appliance 200 is operating.

[0063] Moreover, the presence or absence of operation of the cooking appliance 200 can be determined based on the captured image.

[0064] Furthermore, whether or not the cooking appliance 200 is operating can be determined based on a combination of at least two of an operation signal for the cooking appliance 200, a control signal for the heating control unit 236, the detection result of the air quality detection unit 610, and a captured image.

[0065] [How to determine whether or not food is cooked] The presence or absence of food can be determined based on the captured image, for example. For example, the presence or absence of food is determined to be present when ingredients or food are included in the captured image.

[0066] [How to determine whether cooking is in progress] The presence or absence of a cooking operation can be determined based on sounds and / or captured images collected by the microphone 160. Sounds collected by the microphone 160 include, for example, cooking operation sounds (e.g., the contact sound of a knife and a cutting board, the sound of frying ingredients, the sound of the contents of a pot or frying pan boiling), the sound of opening and closing a refrigerator, the sound of opening and closing a water tap, etc.

[0067] [How to determine whether or not someone is present] The presence or absence of a person can be determined based on a combination of at least two of the detection results of the person detection unit 630 described below, sounds collected by the microphone 160, captured images, measurement results of the wind speed sensor 170, an area sensor whose detection area is around the cooking system 400, and temperature and vibrations around the cooking system 400.

[0068] The cook information acquisition unit 512 acquires information about a cook who is cooking using the cooking system. There may be one cook or multiple cooks. The information about the cook may be, for example, an image of the cook, biometric authentication, authentication code input, etc. The biometric authentication may be, for example, a fingerprint, face, vein, iris, voiceprint, etc. The cook information acquisition unit 512 receives an image captured by the imaging unit 140, for example, at the start of cooking in the cooking system 400, and registers the image of the cook by storing the image of the cook in the cooker information storage unit 513 as information about the cook.

[0069] Cook identification unit 514 identifies a cook based on information about the cook acquired by cook information acquisition unit 512. Cook identification unit 514 determines whether or not the person appearing in the captured image is a cook, for example, by performing a comparison (matching) process between an image of a cook registered in advance in cook information storage unit 513 and a captured image in which a person is detected by person detection unit 630.

[0070] The terminal information acquisition unit 515 acquires terminal information of an external terminal that transmits an operation instruction to an operation target device from outside the cooking system 400. The terminal information may be, for example, an International Mobile Equipment Identifier (IMEI), a serial number, a model number, etc. For example, when an operation instruction is acquired by the operation instruction acquisition unit 510 during cooking in the cooking system 400, the terminal information acquisition unit 515 acquires terminal information (first terminal information) of the external terminal that transmitted the operation instruction and stores it in the terminal information storage unit 516. The terminal information storage unit 516 also stores in advance terminal information (second terminal information) of the cook's external terminal 700.

[0071] The operation instruction determination unit 517 determines whether or not the operation instruction acquired by the operation instruction acquisition unit 510 during cooking in the cooking system 400 is an operation instruction by a cook. For example, the operation instruction determination unit 517 compares the first terminal information with the second terminal information. If the first terminal information and the second terminal information match, the operation instruction determination unit 517 determines that the operation instruction is an operation instruction by a cook. On the other hand, if the first terminal information and the second terminal information do not match, the operation instruction determination unit 517 determines that the operation instruction is not an operation instruction by a cook. By identifying the cook using the terminal information, it is possible to more reliably identify whether the sender of the operation instruction from outside the cooking system 400 is a cook.

[0072] The execution control unit 518 controls the execution of an operation on the target device based on the operation instruction acquired by the operation instruction acquisition unit 510. When the operation instruction acquired by the operation instruction acquisition unit 510 is an operation instruction from a cook, the execution control unit 518 executes the operation on the target device based on the operation instruction. For example, when the operation instruction is to start the operation of the fan 116 of the range hood 100, the execution control unit 518 outputs an instruction to the range hood control unit 138 to start the operation of the fan 116.

[0073] When the operation instruction determination unit 517 determines that the operation instruction acquired by the operation instruction acquisition unit 510 is an operation instruction by a cook, the execution control unit 518 executes an operation on the operation target device based on the operation instruction regardless of whether cooking is in progress. On the other hand, when the operation instruction determination unit 517 determines that the operation instruction acquired by the operation instruction acquisition unit 510 is not an operation instruction by a cook, the execution control unit 518 does not execute an operation on the operation target device based on the operation instruction as a general rule. An exception to the case where an operation is executed on the operation target device based on the operation instruction even when it is determined that the operation instruction is not an operation instruction by a cook will be described later.

[0074] The cooking data acquisition unit 519 acquires the cooking data by receiving it through the cooking system communication unit 620. Details of the cooking data will be described later.

[0075] The cooking data storage unit 520 stores the cooking data acquired by the cooking data acquisition unit 519. The cooking data storage unit 520 has a storage area large enough to simultaneously store multiple pieces of cooking data.

[0076] The cooking data execution unit 521 reads out and executes cooking data stored in the cooking data storage unit 520. More specifically, the cooking data execution unit 521 controls the range hood 100 and the cooking appliance 200 according to the operation details of the range hood and the cooking appliance of the cooking data. The range hood 100, for example, starts / ends the operation of the fan 116 and / or the filter 118, or turns on / off the lighting, according to the instruction from the cooking data execution unit 521. Also, the cooking appliance 200, for example, starts / ends the operation of the heat source 210, according to the instruction from the cooking data execution unit 530.

[0077] When the operation instruction judgment unit 517 judges that the operation instruction acquired during cooking in the cooking system 400 is not an operation instruction from the cook, the execution confirmation unit 523 confirms with the cook whether or not to allow the cook to perform an operation on the target device based on the operation instruction.

[0078] (Third cooking state detection unit 600) The third cooking state detection unit 600 detects the cooking state of the food. The third cooking state detection unit 600 has, for example, an air quality detection unit 610. The air quality detection unit 610 can be a sensor that detects substances that make up the air (e.g., oxygen, carbon monoxide, carbon dioxide, etc.), substances contained in the air (e.g., moisture, oil, dust, odorous substances, etc.), temperature, and humidity.

[0079] Hereinafter, at least one of the first cooking state detection unit 235, the second cooking state detection unit 135, and the third cooking state detection unit 600 will be simply referred to as a "cooking state detection unit." Also, at least one of the first temperature detection unit and the second temperature detection unit 133 will be simply referred to as a "temperature detection unit."

[0080] The cooking system communication unit 620 is a communication interface for transmitting and receiving data between the cooking system control unit 500 and the range hood 100, the cooking appliance 200, the external terminal 700, an external server, and the like.

[0081] The human detection unit 630 detects a person around the operation target device of the cooking system 400 based on the detection result of the human presence sensor 150. The human detection unit 630 may be configured to use not only the detection result of the human presence sensor 150 but also an image captured by the imaging unit 140. The human detection unit 630 may be configured to detect a person around the operation target device based on the on / off of the illuminator of the range hood 100, the sound collected by the microphone 160, the GPS location information of the external terminal 700, etc.

[0082] (External terminal 700) 6 is a schematic block diagram illustrating a configuration of an external terminal 700. The external terminal 700 may be, for example, a mobile terminal such as a smartphone, a personal digital assistant, or a notebook personal computer, a smart speaker terminal, etc. The external terminal 700 has a light-emitting unit 710, a sound output unit 720, a display unit 730, an external terminal operation unit 740, an external terminal communication unit 750, and an external terminal control unit 760.

[0083] In this embodiment, the cook can use the external terminal 700 to perform various operations on the target devices from outside the cooking system 400. The external terminal 700 executes a specific application software and accepts input operations by the cook corresponding to the operations of each of the target devices. The external terminal 700 outputs operation instructions corresponding to the operations of each of the target devices to the target devices from outside the cooking system 400. The external terminal 700 transmits data of the operation instructions to the cooking system 400 using known network technologies such as a LAN (Local Area Network), a WAN (Wide Area Network), and the Internet, wireless communication technologies, and the like. The cooking system 400 receives the operation instructions from the external terminal 700 and performs operations on the target devices based on the operation instructions. The cook can also use the external terminal 700 to download cooking data from an external server and view cooking guides.

[0084] The light emitting unit 710 includes, for example, an LED (Light Emitting Diode), and is used, for example, to emit various warnings and the like.

[0085] The sound output unit 720 includes, for example, a speaker, and outputs warning sounds and cooking guides.

[0086] The display unit 730 includes, for example, a liquid crystal display, and displays various information including cooking guides.

[0087] The external terminal operation unit 740 is equipped with a touch pad and accepts input from the cook.

[0088] The external terminal communication unit 750 transmits and receives control signals and data to and from the cooking system 400.

[0089] The external terminal control unit 760 comprehensively controls the light emitting unit 710 , the sound output unit 720 , the display unit 730 , the external terminal operation unit 740 , and the external terminal communication unit 750 .

[0090] (Cooking data) FIG. 7 is a schematic diagram illustrating the configuration of cooking data. The cooking data of this embodiment is a set of data including a recipe for a specific dish and various data corresponding to the recipe. Cooking data is created for each recipe of the dish. For example, a range hood manufacturer creates cooking data for recipes of multiple dishes in advance and stores the data in a storage device such as an external server (not shown). The cooking data may be pre-stored (preset) in the cooking data storage unit 520. The cooking system 400 may be configured so that a cook inputs cooking data to the cooking system 400 through, for example, an external terminal 700, and stores the cooking data in the cooking data storage unit 520. Furthermore, cooking data created by an unspecified number of creators of cooking data may be stored in an external server.

[0091] 7, the cooking data may include, for example, recipe information 11, range hood operation details 12, cooking device operation details 13, and task details 14. The cooking data may include data other than these data, or may not include some of these data.

[0092] The recipe information 11 is information about a recipe for a specific dish. The recipe information 11 includes, for example, information about ingredients, the quantity or amount of each ingredient, work content, cooking steps, utensils to be used, etc., for the specific dish.

[0093] The cooking data includes a number of steps that are ordered in advance according to the cooking steps of the recipe information 11. In this specification, the process (the smallest step) performed in each cooking step of the recipe information 11 is also referred to as a sub-step (or simply a "step"). Also, from the viewpoint of the cooking state of the food, a group of sub-steps that are performed consecutively is referred to as a step (major step). The cooking data includes eight steps (major steps), from step 1 to step 8. The classification of steps (sub-steps and major steps) is set in advance by the creator of the cooking data.

[0094] The range hood operation details 12 include, for example, information regarding the operation of the fan 116 and / or the filter 118 in accordance with the recipe information 11. The range hood operation details 12 include, for example, the start of exhaust (start of operation of the fan 116), air volume, set time, etc. The output value and rate of change of the air volume at each time from the start time may be stored in a table. The range hood operation details 12 may also include information regarding the operation of the filter 118, lighting, etc. The range hood operation details 12 may also include information regarding the audio output operation in accordance with the recipe information 11. The audio includes cooking guide audio and warning sounds.

[0095] The operation details 13 of the cooker include, for example, information regarding the operation of the heat source 210 in accordance with the recipe information 11. The operation details 13 of the cooker include, for example, the start of heating (start of operation of the heat source 210), heating power, set time, etc. The output value and rate of change of the heating power at each time from the start time may be stored in a table. The operation details 13 of the cooker may also include information regarding the output operation of the display unit of the operation unit 240 of the cooker 200. The operation details 13 of the cooker may include information regarding the audio output operation in accordance with the recipe information 11. The audio includes cooking guide audio and warning sounds.

[0096] The work content 14 includes information about the work of the cook. The work content 14 may be, for example, the content of the work required of the cook (or the appliance, if the appliance is used), such as mixing, turning, shaking the pot, putting on / removing the lid, and adding / removing something. The work content 14 is not the operation of the range hood 100 and the cooking appliance 200 themselves. The work content 14 may also be used as data for generating a cooking guide, for example.

[0097] The recipe data execution unit 521 executes each step (each sub-step) in order according to the recipe procedure of the recipe data.

[0098] (Control method of cooking system 400) Fig. 8 is a flowchart for explaining the processing procedure of the control method of the cooking system 400 of this embodiment. The processing shown in the flowchart in Fig. 8 is realized by executing a control program by the CPU of the cooking system control unit 500. Fig. 9 is a diagram for explaining a method for determining whether cooking is in progress in the cooking system 400.

[0099] 8, first, the operation instruction acquisition unit 510 receives an operation instruction for the device to be operated (step S101). For example, the operation instruction acquisition unit 510 acquires the operation instruction for the range hood 100 by receiving it from the external terminal 700 outside the cooking system 400 through the cooking system communication unit.

[0100] Next, the cooking judgment unit 511 judges whether cooking is in progress in the cooking system 400 (step S102). The cooking judgment unit 511 judges whether cooking is in progress in the cooking system 400 based on judgment information such as whether the range hood is operating, whether the cooking appliance is operating, whether an object is to be cooked, whether a cooking operation is being performed, and whether a person is present. Fig. 9 shows judgment results of whether cooking is in progress for typical combinations of judgment information. Note that nine combinations, No. 1 to 9, are illustrated in the figure, but the present invention is not limited to these combinations.

[0101] For example, when the cooking appliance 200 is operating (whether the cooking appliance is operating: yes), the cooking judgment unit 511 judges that the cooking system 400 is “cooking” regardless of the operation of the range hood, the presence or absence of food to be cooked, the presence or absence of cooking operation, and the presence or absence of people.

[0102] In addition, the cooking judgment unit 511 judges that the cooking system 400 is “cooking” when the heating cooker 200 is not operating (whether the heating cooker is operating: no), when the range hood is operating, and when there is food to be cooked, regardless of whether cooking is being performed or whether people are present.

[0103] Furthermore, the cooking determination unit 511 determines that the cooking system 400 is "cooking" when there is food to be cooked and a cooking operation is being performed, and when there is food to be cooked and someone is present, regardless of whether the range hood is in operation or not, and whether the heating cooker is in operation or not. Although not shown in the figure, the cooking system 400 also determines that it is "cooking" when there is food to be cooked, a cooking operation, and someone is present.

[0104] If cooking is not in progress in the cooking system 400 (step S102: NO), the execution control unit 518 executes the operation on the operation target device based on the operation instruction (step S106), and ends the process (END).

[0105] On the other hand, if cooking is in progress in the cooking system 400 (step S102: YES), the cooker information acquisition unit 512 acquires information about the cook who is cooking (step S103). For example, when cooking begins in the cooking system 400, the cooker information acquisition unit 512 acquires an image captured by the imaging unit 140 and stores the image of the cook in the cooker information storage unit 513 as information about the cook, thereby registering the cook. It is also possible to change the registration of a cook during cooking. When the cook is changed, a new image of the cook is acquired by the imaging unit 140, and the image of the cook is stored in the cooker information storage unit 513 as information about the cook, thereby updating the registration of the cook.

[0106] Next, the cook identifying unit 514 identifies the cook (step S104). The cook identifying unit 514 identifies the cook by, for example, performing a comparison process between the image of the cook and the image captured by the imaging unit 140.

[0107] Next, the operation instruction determination unit 517 determines whether the acquired operation instruction is an operation instruction by a cook (step S105). As described above, the operation instruction determination unit 517 determines whether the operation instruction acquired by the operation instruction acquisition unit 510 is an operation instruction by a cook, depending on whether the person in the captured image corresponds to a cook. If the operation instruction acquired by the operation instruction acquisition unit 510 is an operation instruction by a cook (step S105: YES), the execution control unit 518 executes the operation of the target device based on the operation instruction (step S106), and ends the process (END).

[0108] On the other hand, if the operation instruction acquired by the operation instruction acquisition unit 510 is not an operation instruction from a cook (step S105: NO), the execution control unit 518 terminates the process without executing the operation on the target device based on the operation instruction, with the exceptions described below.

[0109] In step S107, the human detection unit 630 detects a person around the operation target device. The cook identification unit 514 identifies whether the person detected by the human detection unit 630 is a cook. As an exception, when a cook is around the operation target device, the execution control unit 518 executes an operation on the operation target device based on the operation instruction even if the operation instruction acquired by the operation instruction acquisition unit 510 is determined not to be an operation instruction by the cook. When a cook is around the operation target device, even if an operation unintended by the cook is executed by remote operation by someone other than the cook, the cook can immediately notice and take appropriate action.

[0110] Furthermore, the execution confirmation unit 522 confirms with the cook whether or not to permit the cook to execute the operation on the operation target device based on the operation instruction. As an exception, when the cook permits the cook to execute the operation on the operation target device based on the operation instruction, the execution control unit 518 executes the operation on the operation target device.

[0111] As such, as an exception, if a cook is present around the target device and / or the cook has permitted execution of an operation on the target device (step S107: YES), the process proceeds to step S106. On the other hand, if a cook is not present around the target device and the cook has not permitted execution of an operation on the target device (step S107: NO), the execution control unit 518 proceeds to step S108.

[0112] In step S108, the execution control unit 518 judges whether automatic cooking is in progress or cooking guide is being output. If automatic cooking is not in progress and cooking guide is not being output (step S108: NO), the execution control unit 518 proceeds to the process of step S106. On the other hand, if automatic cooking is in progress and / or cooking guide is being output (step S108: YES), the execution control unit 518 ends the process without performing an operation on the operation target device based on the operation instruction (END). In this way, the execution control unit 518 does not perform an operation on the operation target device based on the operation instruction only during the automatic operation of the operation target device or while the cooking guide is being performed. Here, the automatic operation includes, for example, a function of keeping a constant temperature in the cooking appliance 200 and a temperature tracking type automatic operation in the range hood 100.

[0113] In addition, the execution control unit 518 does not execute operations on the target device based on operation instructions only during automatic operation of the target device based on the cooking data acquired by the cooking data acquisition unit 519, or while cooking guidance based on the cooking data is being performed.

[0114] The cooking system 400, the range hood 100, the cooker 200, and the control method for the cooking system 400 of the present embodiment described above have the following advantages.

[0115] When it is determined that the operation instruction from outside the cooking system 400 is an operation instruction from the cook, the operation of the operation target device based on the operation instruction is executed. On the other hand, when it is determined that the operation instruction from outside the cooking system 400 is not an operation instruction from the cook, the operation of the operation target device based on the operation instruction is not executed. Therefore, while maintaining the remote operation of the operation target device by the cook, it is possible to prevent or suppress remote operation by anyone other than the cook. As a result, it is possible to prevent or suppress the execution of an operation unintended by the cook.

[0116] The cooking system, range hood, cooking appliance, and cooking system control method of the present invention have been described above using the embodiments. However, the technical scope of the cooking system, range hood, cooking appliance, and cooking system control method of the present invention is not limited to the scope described in the embodiments. For example, inventions that are constructed by a person skilled in the art by simply replacing each element of the present embodiment are included in the technical scope of the present invention.

[0117] For example, in the embodiment, a part or all of the processes executed by the control program may be replaced with hardware such as a circuit.

[0118] In addition, the above-mentioned flowchart may include steps other than those shown in the flowchart, or may not include some steps. The order of the steps is not limited to the above-mentioned embodiment. Furthermore, each step may be combined with other steps and executed as one step, may be included in other steps and executed, or may be divided into multiple steps and executed.

[0119] In the above embodiment, the cooking system control unit 500, the third cooking state detection unit 600, and the cooking system communication unit 620 are installed independently of the range hood 100 and the cooker 200. However, the range hood 100 or the cooker 200 may be configured to include the cooking system control unit 500, the third cooking state detection unit 600, and the cooking system communication unit 620.

[0120] In addition, the function of determining whether an operational instruction from outside the cooking system 400 is an operational instruction from a cook may be configured to be possessed by an external server or external terminal 700. [Explanation of symbols]
