Description

[Technical field]

[0001] This relates to a kitchen system equipped with a range hood and a gas stove. [Background technology]

[0002] Conventionally, there is known a technique for adjusting the flame power so that the flame does not overflow around a pot or the like placed on a gas stove. For example, Patent Document 1 discloses a flame power adjustment device for a gas stove that can automatically adjust the flame power so that the flame does not overflow around the heated object. This flame power adjustment device is equipped with an infrared image sensor that is arranged to overlook the gas stove and measures the temperature distribution in a predetermined range centered on a burner provided on the gas stove. Based on the temperature difference between the heated object on the burner and its surroundings measured by the infrared image sensor, it is determined whether the burner flame has overflowed around the heated object, and when it is determined that the flame has overflowed, the flame power of the burner is reduced. In addition, based on the temperature difference between the heated object on the burner and its surroundings measured by the infrared image sensor, the size of the heated object is determined, and the flame power of the burner is adjusted according to the determined size of the heated object to prevent the flame from overflowing around the heated object.

[0003] [Patent Document 1] JP 2010-14342 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, the pan diameter is determined after the burner is ignited, so flame overflow may occur immediately after ignition.

[0005] The present invention has been devised in consideration of the above circumstances, and provides a kitchen system that is safe, convenient, and easy to use for users, and does not cause flame overflow even immediately after ignition. [Means for solving the problem]

[0006] In order to solve the above problems, a kitchen system is provided that includes a range hood, a gas stove with an operation unit that accepts heat input from a user, and a control unit, in which the range hood has a detection means for detecting the size of a heated object placed on the gas stove, and the control unit sets the heat based on the size of the heated object detected by the detection means and in accordance with standard information that previously corresponds the size of the heated object to the heat power, and in which the gas stove ignites at the heat power set by the control unit in accordance with the standard information if the heat power specified by the operation unit exceeds the heat power set in accordance with the standard information. According to this, by setting the heat level that will not cause flame overflow according to standard information based on the detected size of the heated object and then igniting the food, it is possible to provide a safe kitchen system that will not cause flame overflow even immediately after ignition.

[0007] Furthermore, the control unit may be characterized in that it changes the reference information when a relaxation requirement for relaxing the reference information is satisfied. According to this, when the relaxation requirements are met, the standard information can be changed to control the fire power so as not to cause flame overflow, achieving both safety and convenience.

[0008] The range hood and / or gas stove may further include a user recognition unit that recognizes users who use the range hood and / or gas stove, a usage status acquisition means that acquires, for each user recognized by the user recognition unit, information including at least cooking behavior information of the user performed on heated items, and a learning unit that learns the information acquired by the usage status acquisition means as cooking information, and the control unit may be characterized in that it determines whether the relaxation requirements are satisfied based on the output of the trained model generated by the learning unit. According to this, by determining whether or not the relaxation requirements are met based on a trained model that has learned information including the cooking behavior of each user on at least the heated item, the standard information changes taking into account cooking information such as the user's level of proficiency and the cooking content, so that the heat is not uniformly limited regardless of the user or cooking information, and it is possible to control the heat without causing flame overflow, achieving both safety and convenience.

[0009] Furthermore, the control unit may be characterized in that, even if the relaxation requirements are satisfied, if the information acquired by the usage status acquisition means corresponds to a relaxation prohibition condition, the control unit sets the heating power as if the relaxation requirements are not satisfied. According to this, even if the relaxation requirements are met, if information including information on the user's cooking actions performed on the heated items falls under the relaxation prohibition conditions, the heat power can be set as if the relaxation requirements are not met, thereby providing a highly safe kitchen system.

[0010] Furthermore, the control unit may be characterized by having a non-comparison mode in which the heat level instructed by the operation unit is not compared with the heat level according to the reference information. According to this, by having a non-comparison mode that does not compare the heat level specified by the operating unit with the heat level according to the reference information, in the non-comparison mode the stove can be ignited at the heat level specified by the user, thereby providing a convenient kitchen system.

[0011] Furthermore, the device may further include an informing unit that notifies a user, and the informing unit may be configured to issue a notification to call attention when the control unit is set to the non-comparison mode. According to this, a certain level of safety can be ensured by issuing a warning alert when the non-comparison mode is set.

[0012] The device may further include a user recognition unit that recognizes users using the range hood and gas stove, a usage status acquisition means that acquires usage status of the range hood and gas stove for each user recognized by the user recognition unit, and a learning unit that learns the usage status of the range hood and gas stove acquired by the usage status acquisition means as cooking information, and the control unit may be characterized in that it sets the device to a non-comparison mode when it is determined that the user using the device satisfies the relaxation requirements for relaxing the standard information based on the output of the trained model generated by the learning unit. According to this, if it is determined that the relaxation requirements for the user to relax the standard information are met based on a trained model that has learned information including the user's cooking actions on heated items, the non-comparison mode can be set, allowing any authorized user to ignite the stove at the heat level they specify, thereby providing a convenient kitchen system while ensuring a certain level of safety. Effect of the Invention

[0013] As described above, according to the present invention, it is possible to provide a kitchen system that does not cause flame overflow even immediately after ignition, is easy for users to use, and is safe and convenient. [Brief description of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. <First Example> A kitchen system 100 in this embodiment will be described with reference to Figs. 1 to 10. The kitchen system 100 includes a range hood 10 installed on the ceiling or wall of a kitchen, a gas stove 20 installed in an opening in the top plate of a kitchen counter, a mobile terminal 30 capable of communicating with the range hood 10 and the gas stove 20, and a server 40 capable of communicating with the range hood 10, the gas stove 20, and the mobile terminal 30. The range hood 10 is installed above the gas stove 20, and uses the hood to capture oily smoke and water vapor generated from ingredients and water heated by heated objects such as pots, frying pans, and kettles placed on the gas stove 20, and exhausts the oily smoke and water vapor to the outside using a fan. The heated object includes both the pot and the ingredients heated by the pot, and the temperature of the heated object refers to a temperature including both the temperature of the pot and the temperature of the ingredients heated by the pot. Furthermore, the range hood 10 need not necessarily be installed above the gas stove 20, but may be installed diagonally above the gas stove 20 (usually on the far side of the gas stove 20).

[0016] Range hood 10 is equipped with infrared sensor 11 (RH detection means 11) that detects the size and temperature of a heated object placed on gas stove 20, and camera 12 (RH user recognition unit 12) that recognizes a user who is using either or both of range hood 10 and gas stove 20. Infrared sensor 11 is an infrared sensor (or infrared camera) that is attached to the hood of range hood 10 as shown in Fig. 2 and detects the temperature in an area that covers the upper surface of gas stove 20 below. Cameras 12 are attached to the left and right sides of the hood of range hood 10 as shown in Fig. 2 and capture images of the area where a cook stands, including the face and hands of the cook who is in front of the heating area.

[0017] The infrared sensor 11 has a detection range that is the mesh area that covers the top surface of the gas stove 20 as shown in Fig. 3, has a pixel count of 80 x 60, and has temperature analysis capabilities equivalent to a high-precision thermal imaging camera. In addition to the temperature of a pot or the like, the infrared sensor 11 can also detect the surface temperature of ingredients, the temperature of ingredients, changes in the surface of a liquid, and the like. The infrared sensor 11's ability to detect the surface temperature of ingredients, the temperature of ingredients, changes in the surface of a liquid, and the like allows the kitchen system 100 to check the doneness of ingredients, temperature changes when ingredients are added and after they are added (cooking process), and bubbles and convection on the surface of a liquid when boiling food.

[0018] For example, when the infrared sensor 11 detects the temperature of a pot placed on a trivet and the food inside it, it detects the temperature of the edge of the pot in a circular shape, detects the temperature of the food in the center of the circumference, and detects the temperature of the bottom of the pot (more precisely, the upper surface of the bottom of the pot) between the food and the edge of the pot. Therefore, the temperature detected by the infrared sensor 11 may be the maximum temperature in the detection range, or the average of the heating areas (inside the circular edge of the pot) on one or more trivets, or the temperature of each different object such as the pot and the food. In addition, the infrared sensor 11 can detect the physical size of the pot (such as the diameter of the pot) by detecting the edge of the pot on the circumference using the temperature. In addition, the infrared sensor 11 may also function as a distance measuring sensor using infrared light, which allows the kitchen system 100 to measure the distance from the range hood 10 to the top plate of the gas stove 20 and the top edge of the pot placed on it. In this embodiment, the physical size of the pot or the like is detected using the infrared sensor 11, but this is not limited to this, and for example, detection may also be performed using an optical or ultrasonic displacement sensor or a length measurement sensor using laser light.

[0019] The camera 12 is a camera capable of recognizing a user who uses the kitchen system 100, and a facial image acquired by the camera 12 is transmitted to a control unit (either the RH control unit 17, the BN control unit 27, or the MT control unit 37 of the mobile terminal 30). The kitchen system 100 thereby recognizes the cook (the user of the kitchen system 100) from the image. The kitchen system 100 uses a known technology for recognizing / identifying human faces as a method for recognizing or identifying the cook. It is also preferable that the camera 12 can capture the cook's actions, such as putting ingredients in and taking them out of a pot, stirring, and flipping them over. The camera 12 may be configured to not only acquire an image of the area where the cook is standing, including the cook's face and hands, but also to acquire an image of the top and side of a pot on the gas stove 20 diagonally below.

[0020] The range hood 10 also includes an RH display unit 13, an RH speaker 14, an RH operation input unit 15, and an RH light 16. The RH display unit 13 is attached to the front of the hood and visually notifies the user of the kitchen system 100 of various information, and is a liquid crystal display that displays messages such as the operating status and warnings as necessary. The RH speaker 14 is attached to the front of the hood and audibly notifies the user of the kitchen system 100 of various information, and is a speaker that transmits messages such as the operating status and warnings as voice as necessary. The RH operation input unit 15 is attached to the front of the hood and is composed of a touch panel and buttons that are operated by the user of the kitchen system 100. The RH operation input unit 15 accepts operations by the user to turn the range hood 10 on / off and set the air volume (for example, strong, medium, weak). The RH lighting 16 is attached to the underside of the hood (not shown) and illuminates the gas stove 20 from above, providing a certain level of illuminance to the gas stove 20, the upper surface of the object to be heated, the face of the cooker, and the like.

[0021] The range hood 10 also includes an RH control unit 17, an RH storage unit 18, an RH communication unit 19, and an RH learning unit 1A. The RH control unit 17 is typically a microprocessor that executes a program for controlling the entire range hood 10. The RH storage unit 18 is a memory in which the programs executed by the RH control unit 17 and various parameters are stored. The RH communication unit 19 has a network interface (e.g., infrared communication or Bluetooth (registered trademark)) capable of communicating with the BN communication unit 29 of the gas stove 20, and a network interface (e.g., Wifi function) capable of communicating with the MT communication unit 39 of the mobile terminal 30 and the SV communication unit 49 of the server 40 on the Internet via a wireless router, and may further have a function of a network interface (e.g., Bluetooth) capable of communicating with the MT communication unit 39 of the mobile terminal 30 without via a wireless router.

[0022] The RH learning unit 1A has a usage status acquisition means for acquiring information including at least information on the cooking behavior of the user on the heated object among image information of the content and method of cooking for each user captured by the camera 12, image information of the type and placement position of the non-heated object, and image information showing a foreign object such as the side of a pan or the like or a state in which the pan or the like is tilted, and machine-learns the information acquired by the usage status acquisition means as cooking information. In reality, some of the image information for machine learning is stored in the RH storage unit 18 immediately after capture, but most of it is transferred to the server 40 and stored in the SV information storage unit 48. Then, the SV control unit 47 of the server 40 periodically performs machine learning based on these image information, and a trained model is generated. The generated trained model is periodically downloaded and stored in the RH storage unit 18. The RH control unit 17 uses the stored trained model to perform various estimations, judgments, etc., which will be described later. The RH learning unit 1A may update the parameters of the trained model using the most recent cooking information stored in the RH storage unit 18.

[0023] The machine learning method is not particularly limited, and is appropriately selected from known methods. In this machine learning, it is preferable to generate a trained model that outputs the type of food (boiled food, fried food, stir-fried food, boiling water, etc.) from the cooking content, the cook's proficiency (efficient, slow, timely cooking intervention, accuracy of placing the pot on the trivet, etc.) from the cooking method, the cooking utensils used (pot, frying pan, kettle, etc.) from the type of heated object, and the placement accuracy of the heated object on the trivet from the placement position of the heated object. In addition, the RH storage unit 18 stores the standard information and relaxed requirements described below, and information on the users of the kitchen system 100, and may further store statistical information such as the food to be made, the cooking utensils used, and the accuracy of the placement position for each user.

[0024] The gas stove 20 includes a BN operation panel 21 (BN user recognition unit 21), a BN display unit 23, a BN heat operation unit 25, a BN control unit 27, a BN storage unit 28, and a BN communication unit 29. The BN operation panel 21 has a fingerprint sensor for recognizing the user, and a button function for setting / canceling a non-comparison mode described later and for selecting a cooking menu, and device operations other than heat operation are performed by operating the BN operation panel 21. User recognition may be performed by inputting a user ID into the BN operation panel 21. This makes it possible to know which user selected which cooking menu of the stove to cook. The BN display unit 23 is a liquid crystal display attached to the front side of the top surface of the gas stove 20 and visually notifying the user of the kitchen system 100 of various information.

[0025] The BN heat operation unit 25 is attached to the front of the gas stove 20 and is composed of buttons operated by the user of the kitchen system 100. The BN heat operation unit 25 accepts operations by the user to turn the gas stove 20 on / off and set the heat of each burner. The BN control unit 27 is typically a microprocessor that executes a program that controls the entire gas stove 20. The BN storage unit 28 is a memory in which the programs executed by the BN control unit 27 and various parameters are stored. Like the RH storage unit 18, the BN storage unit 28 may store information on the users of the kitchen system 100, and statistical information for each user, such as the contents of the dish to be made, the cooking utensils used, and the accuracy of the placement position. The BN communication unit 29 is a network interface that can communicate with the RH communication unit 19 of the range hood 10, and may further have a network interface that can directly communicate with the mobile terminal 30 and the server 40.

[0026] As a typical example of cooperation between the two, for example, when a user operates the BN fire power operation unit 25 to turn on the gas stove 20, the BN control unit 27 puts the burner in a state in which it can be ignited, and instructs the BN communication unit 29 to transmit a signal indicating that this state has been reached to the RH communication unit 19 of the range hood 10. When the RH communication unit 19 receives this signal, it transmits it to the RH control unit 17. Upon receiving this signal, the RH control unit 17 may, for example, turn on the RH lighting 16.

[0027] Also, when the user operates the BN heat power operation unit 25 to ignite one burner at a medium heat power, a signal to that effect is similarly transmitted to the RH control unit 17, and the RH control unit 17, having received the signal, rotates the fan to start exhausting at a low air volume. Also, when the infrared sensor 11 or the pot bottom sensor (not shown) detects that the frying pan placed on the trivet by the user has become hot, a signal to that effect is similarly transmitted to the RH control unit 17, and the RH control unit 17 may rotate the fan quickly to exhaust at a strong air volume. Also, when the infrared sensor 11 detects that the frying pan has become hotter than a certain temperature, the BN control unit 27 may reduce the heat power of the burner.

[0028] The mobile terminal 30 is typically a smartphone and is equipped with an MT control unit 37 consisting of a microprocessor, an MT memory unit 38 consisting of memory, an MT communication unit 39 having a network interface capable of communicating with a wireless router (e.g., Wi-Fi function), a network interface capable of close-proximity communication (e.g., Bluetooth), a network interface connectable to a telephone line, etc., an MT display unit 33 consisting of a touch panel with display function and operation input function, and an MT operation input unit 35.

[0029] Various applications can be additionally installed on the mobile terminal 30, and a dedicated application capable of operating the kitchen system 100 is installed. When the dedicated application is downloaded from an external network to the mobile terminal 30 via the MT communication unit 39, it is stored in the MT storage unit 38 and becomes executable by the MT control unit 37. When the dedicated application is activated by a user from the touch panel, it controls the range hood 10 and the gas stove 20 constituting the kitchen system 100, and acquires information from these devices and displays it on the touch panel. The dedicated application executed by the MT control unit 37 may be the control unit of the kitchen system 100. For example, the mobile terminal 30 displays the state of the heated object captured by the camera 12 as an image (or a video) on the touch panel, adjusts the heat of the gas stove 20 according to the state by the user's operation, and adjusts the air volume of the range hood 10 according to the adjusted heat. Furthermore, like the RH memory unit 18, the MT memory unit 38 may store information about users of the kitchen system 100, as well as statistical information for each user, such as the type of dish to be made, the cooking utensils used, and the accuracy of the placement position.

[0030] The server 40 is a computer system installed remotely from the kitchen, on a so-called cloud. The server 40 includes an SV control unit 47 having a calculation function and controlling the entire system, an SV information storage unit 48 consisting of a large-capacity memory and storage device, and an SV communication unit 49 accessible via the Internet, and is controlled by a control program such as a known OS (Operating System). As described above, the SV control unit 47 performs machine learning based on the data stored in the SV information storage unit 48, generates a trained model, and stores the trained model in the SV information storage unit 48.

[0031] 4 and 5, the control process of each device until the gas stove 20 is ignited will be described. Note that in this embodiment, the control unit of the kitchen system 100 will be described as the RH control unit 17 of the range hood 10, but this is not limited thereto, and a function equivalent to that of the RH control unit 17 may be realized by being executed by a dedicated application executable by the MT control unit 37 of the mobile terminal 30 or the BN control unit 27 of the gas stove 20. Note that S in the flowchart indicates a step.

[0032] In S100, when the user places a cooking utensil on the trivet while the power is on, the BN control unit 27 of the gas stove 20 detects that the cooking utensil has been placed on the trivet by a pot bottom sensor (not shown). When the cooking utensil is detected, the BN control unit 27 detects which user of the kitchen system 100 registered in the kitchen system 100 (BN storage unit 28) is about to use the cooking utensil by the fingerprint sensor of the BN operation panel 21 in S102. The detection of user information by the BN control unit 27 is not limited to detection by a fingerprint sensor, and may be detection by periodically receiving information from the RH user recognition unit and detecting this as user information. In S104, the BN control unit 27 acquires usage status information including cooking behavior information related to the detected user (for example, setting information of the cooking menu set by the user, setting information of the heat dial performed before ignition, information on heat adjustment during cooking, etc.) from the BN storage unit 28. This usage status information is used not only for the reference information setting process but also for machine learning in the RH learning unit 1A. In S106, the BN control unit 27 transmits the information acquired from the BN communication unit 29 and information that the cooking utensil has been placed from the BN communication unit 29 to the range hood 10.

[0033] In S200, the RH control unit 17 receives the information transmitted by the gas stove 20 through the RH communication unit 19. In S202, the RH control unit 17 receives the cooking utensil detection information and detects the size and type of the cooking utensil using the infrared sensor 11 (RH detection means 11). In this embodiment, the range hood 10 receives data from the gas stove 20 and detects the size and type of the cooking utensil, but it may always detect the size and type of the cooking utensil itself and perform subsequent processing without waiting for data to be received from the gas stove 20. In S204, the RH control unit 17 refers to standard information (heat setting table) corresponding to the size of the cooking utensil shown in FIG. 6 stored in the RH storage unit 18 based on the detected size of the cooking utensil, and sets the heat according to this standard information.

[0034] As shown in the figure, the reference information is preset as default values ​​such that when the size of the cooking utensil is "small" (diameter 18 cm or less), the heating power is set to 3, and as the diameter increases, the heating power increases, and when the cooking utensil is "extra large" (diameter 30 cm or more), the heating power is set to 6. In this way, the RH control unit 17 sets the heating power according to the reference information that previously associates the size of the object to be heated with the heating power, based on the size of the object to be heated (cooking utensil) detected by the RH detection means 11. Note that for cooking utensils with special shapes such as hot sandwich makers, the maximum heating power that does not cause flame overflow is set based on the size of the short side.

[0035] In S206, the RH control unit 17 refers to the relaxation requirement table stored in the RH storage unit 18 shown in FIG. 7, and checks whether the case corresponds to a case in which the relaxation requirement is satisfied, or whether the case corresponds to a case in which the relaxation requirement is satisfied but a relaxation prohibition condition is satisfied. This process will be described in detail with reference to FIG. 8. In S300, if the reference information has been changed, the RH control unit 17 clears the reference information and returns it to a default value. If the reference information has been changed, it is cleared once here. In other words, even if the reference information has been changed, it is reset for each ignition. In S302, the RH control unit 17 checks whether the relaxation requirement is satisfied.

[0036] As shown in FIG. 7, the relaxation requirements are, for example, that the user has a high level of proficiency, that the number of times the user uses the cooking utensil is a predetermined number or more (10 times in the example), that the accuracy of the placement position of the cooking utensil placed by the user on the trivet is high, and that the number of times the user cooks the same thing is a predetermined number or more (20 times in the example). The relaxation requirements may be satisfied if one specific relaxation requirement item among the relaxation requirements in FIG. 7 is satisfied, or may be satisfied if multiple relaxation requirement items are satisfied. They can be changed as appropriate. In addition, the RH control unit 17 may determine whether the relaxation requirements are satisfied based on the output of the trained model generated by the RH learning unit 1A. According to this, by determining whether the relaxation requirements are satisfied based on the trained model that has learned information including the cooking behavior information of the user performed on at least the heated object for each user, the standard information changes taking into account cooking information such as the user's level of proficiency and cooking contents, and therefore the heat is not uniformly limited regardless of the user or cooking information, and it is possible to control the heat without causing flame overflow, which is both safe and convenient.

[0037] The user's level of proficiency is learned through machine learning based on the number of times the user cooks on a daily basis, how they use the pot, and cooking interventions appropriate to the cooking process (for example, cooking ingredients to the optimum degree of browning), so the RH control unit 17 can estimate the level of proficiency of the user who is about to use it. The number of times that a user has used a cooking utensil is stored as statistical information by determining the identity of the cooking utensil from the image information of the camera 12, so that the number of times that the user is about to use the cooking utensil can be obtained. The high accuracy of the placement position of the cooking utensil placed by the user on the trivet is determined from the image information of the camera 12, and whether the cooking utensil is placed in the center of the trivet when igniting and whether the range of deviation from the center is small even during cooking is learned by machine learning, so that the placement accuracy of the user who is about to use the cooking utensil can be estimated. The number of times that the user has cooked the same thing is estimated from the settings of the automatic cooking menu input to the gas stove 20 and the image information of the camera 12. For example, it is assumed that the image data of the camera 12 recognizes that an omelet rice has been made 20 times. In this state, if an omelet rice is selected as the automatic cooking menu before the stove is ignited, the RH control unit 17 can determine that the number of times the same cooking has been performed before ignition is 20 or more times.

[0038] The skill level of a user may be determined from various actions of the user. For example, as shown in FIG. 9, user A has used a small frying pan 20 times, has high accuracy in placing cooking utensils, and has cooked omelet rice 10 times, which is more frequent and more accurate than user B. For this reason, user A may be considered to be highly skilled and user B may be considered a beginner. Based on this knowledge, since a beginner may place a pot on the trivet out of place, the initial standard information may be strict, and the standard information may be configured to change as the user gains experience. The skill level may also be determined based on whether the user performs appropriate heat control or intervention according to the dish. For example, the user may preheat the pan to an appropriate temperature before putting it in, reduce oil splashes or food splashes, and turn the food over without burning it, and may be determined to be an expert by learning these from image information, temperature information, air quality information obtained from a smoke sensor (not shown), etc.

[0039] If the relaxation requirement is satisfied, the RH control unit 17 checks in S304 whether or not there is a flag indicating that the relaxation prohibition condition is satisfied. If there is a flag indicating that the relaxation prohibition condition is satisfied, for example, when the RH control unit 17 obtains information from the camera 12 that there is paper on the side of the pot or that the pot is placed at an angle, a flag indicating that the relaxation prohibition condition is satisfied is set. If this flag is not set, the RH control unit 17 sets a flag for changing the reference information in S306. If the relaxation requirement is not satisfied and there is no flag indicating that the relaxation prohibition condition is satisfied, the RH control unit 17 sets a flag for changing to the default reference information in S308. In this way, even if the relaxation requirement is satisfied, if the information acquired by the usage status acquisition means corresponds to the relaxation prohibition condition, it is preferable to set the heat power as if the relaxation requirement is not satisfied. This makes it possible to provide a highly safe kitchen system 100.

[0040] If there is a change flag for the reference information, the RH control unit 17, for example, changes the heat from the default value in the heat setting table in Fig. 7 to a larger heat overall as shown in the rightmost column of the lower table in Fig. 8. Note that the heat before the change has a certain margin within the range where the flame does not overflow, but the heat after the change is set to the limit where the flame does not overflow. Note that if the size of the cooking utensil is small, the margin is small to begin with, so there is no need to change it even when the reference information is to be changed.

[0041] The RH control unit 17 may compare the above-mentioned mitigation requirements with the cooking information, and may determine that the mitigation requirements are met, for example, when three out of four items are met. In this way, it is preferable that the RH control unit 17 changes the reference information when the mitigation requirements that mitigate the reference information are met. This makes it possible to control the heat power so as not to cause flame overflow when igniting, while achieving both safety and convenience.

[0042] If there is a change flag and it is determined that the relaxed requirement is satisfied, the RH control unit 17 changes the reference information in S208 of FIG. 4, and sets the reference information with a higher flame power thereafter. This change in the reference information is performed each time the gas stove is ignited. In other words, it is performed each time cooking is performed, and does not rewrite the default reference information that is preset in the gas stove 20. The RH control unit 17 transmits the set reference information to the gas stove 20 in S210. The BN communication unit 29 receives the transmitted reference information in S108, and stores the reference information in the BN storage unit 28.

[0043] Next, the burner control process of the gas stove 20 will be described with reference to Fig. 5. In S150, the BN control unit 27 waits for the user to perform an ignition operation from the BN fire power operation unit 25. When an ignition operation is performed, in S152, the BN control unit 27 checks whether or not the non-comparison mode is set, which does not compare the fire power instructed by the user from the BN fire power operation unit 25 with the fire power according to the reference information.

[0044] Here, the setting process of the non-comparison mode will be described with reference to FIG. 10. In S400, the BN control unit 27 clears the current mode when the power is turned on and sets it to the normal mode (a mode using the reference information that proceeds to No in S152 of FIG. 5). That is, the default value when the gas stove 20 is turned on is the normal mode. Next, in S402, the BN control unit 27 recognizes the user by the fingerprint sensor of the BN operation panel 21, and then checks whether or not the user has entered a change input to set the non-comparison mode on the BN operation panel 21. In addition, the BN control unit 27 may set the non-comparison mode if it is determined that the user who is using the system satisfies the relaxation requirement for relaxing the reference information based on the output of the generated trained model. According to this, if a recognized person is able to ignite the stove with the heat power that he or she specifies, a certain level of safety can be guaranteed and a convenient kitchen system 100 can be provided.

[0045] When there is an input to change to the non-comparison mode, the BN control unit 27 checks in S404 whether the user who inputs the change satisfies the permission conditions. The permission conditions are, for example, based on the proficiency of the user determined by machine learning, and if the proficiency is high, the permission conditions are satisfied. If the user satisfies the permission conditions for changing the mode, the BN control unit 27 issues a notice to call attention in S406, and the BN display unit 23 issues a notice to that effect. According to this, by issuing a notice to call attention when the non-comparison mode is set, a certain level of safety can be guaranteed. Thereafter, the BN control unit 27 transitions to the non-comparison mode in S408. The BN control unit 27 may set the non-comparison mode when it is determined in S402 that the user who is using the device satisfies the relaxation requirement for relaxing the reference information based on the output of the generated trained model. In this case, whether or not the mode change permission conditions are met may be determined not only based on proficiency but also, for example, on the correlation between the cooking content and the pot used (large frying pans are frequently used to boil pasta, and there is no data showing flame overflow in this case).

[0046] 5, the BN control unit 27 checks whether the non-comparison mode set as described above is active, and if the non-comparison mode is active, the BN control unit 27 sets the fire power instructed by the BN fire power operation unit 25 to the burner fire power in S160. Next, the BN control unit 27 ignites at that fire power in S158. In this way, by having a non-comparison mode that does not compare the fire power instructed by the BN fire power operation unit 25 with the fire power according to the reference information, it is possible to ignite at the fire power instructed by the user in the non-comparison mode, and therefore a convenient kitchen system 100 can be provided.

[0047] If the non-comparison mode is not set, the BN control unit 27 checks in S154 whether the fire power instructed by the BN fire power operation unit 25 is equal to or lower than the fire power previously associated with the size of the heated object in the reference information. If the instructed fire power exceeds the fire power according to the reference information, the BN control unit 27 sets the fire power of the reference information to the burner fire power in S156. Then, the BN control unit 27 ignites with that fire power in S158. In this way, even if the user instructs a high fire power, a fire power that does not cause flame overflow according to the reference information based on the detected size of the heated object is set and then ignited, thereby providing a safe kitchen system 100 that does not cause flame overflow even immediately after ignition. Note that if the instructed fire power is equal to or lower than the fire power in the reference information, the BN control unit 27 sets the fire power instructed by the BN fire power operation unit 25 to the burner fire power in S162. Then, the BN control unit 27 ignites with that fire power in S158.

[0048] As described above, the present invention can provide a kitchen system 100 that does not cause flame overflow when ignited, is easy to use for the user, and is safe and convenient.

[0049] The present invention is not limited to the illustrated examples, and may be implemented in any configuration that does not deviate from the scope of the claims. That is, the present invention has been particularly illustrated and described mainly with respect to specific embodiments, but those skilled in the art may make various modifications to the above-described embodiments in terms of the number and other details of the configuration without departing from the scope of the technical idea and purpose of the present invention.
