Description

[Technical Field]

[0001] The present invention relates to a cooking system. [Background technology]

[0002] Patent document 1 describes a heating device that uses a human body detection sensor to detect the presence or absence of a human body in front of the cooking appliance, and controls the heat for cooking at high or high temperatures if no one is present for a specified period of time.

[0003] Patent document 2 also describes an appliance control system that uses a human body detection sensor to detect the presence or absence of a human body in the kitchen, and sets the kitchen lighting pattern when no one is present and the temperature of the cooking appliance is above a reference value. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4992553 [Patent Document 2] Patent No. 6594234 Summary of the Invention [Problem to be solved by the invention]

[0005] For example, if a person cooking food on a gas stove leaves the kitchen to greet a visitor or take care of a child, the food in the pot may continue to heat, leading to cooking failures such as burning or overheating.

[0006] To address this issue, for example, as described in Patent Document 1, a system that controls the heat of a cooking appliance based on the presence or absence of a human body in the kitchen can lead to changes in the heat even if the cook temporarily leaves the kitchen, for example, for cooking that requires a long time to heat or automatic cooking, which can lead to the inconvenience of not being able to perform the necessary cooking.

[0007] Furthermore, as described in Patent Document 2, in the case of a system that sets the kitchen lighting pattern when no one is present and the temperature of the cooking appliance is above a reference value, there is a concern that people who have left the kitchen may not be able to see the change in the lighting pattern, and may not be able to properly notify the user that the food is still being heated.

[0008] For these reasons, there is a demand for a heating and cooking system that can appropriately notify the person cooking according to the heating status when the person cooking leaves the cooking space. [Means for solving the problem]

[0009] The characteristic configuration of the heating cooking system of the present invention is that it comprises a heating cooker that is installed in a cooking space and heats a cooking appliance using a heating unit, an alarm device installed in the cooking space, and a communication unit that transmits information between the heating cooker and the alarm device, and the alarm device has an alarm output unit that outputs alarm information, an audio output unit that outputs the alarm information by voice, a human body detection unit that determines whether a person is present in the cooking space, and a judgment processing unit that sets a time-out time that is shorter the greater the amount of heating heat, based on the amount of heating heat in the heating unit as cooking status information obtained from the heating cooker via the communication unit, and the alarm output unit outputs the alarm information when the time during which a person is not detected by the human body detection unit exceeds the time-out time while heating continues in the heating cooker.

[0010] According to this characteristic configuration, if a person leaves the cooking space where cooking is being performed, the human body detection unit detects the absence of a person. The alarm is configured to set a shorter timeout period for the greater amount of heat generated by the heating unit based on cooking status information transmitted via the communication unit. As a result, for example, if a person performing cooking with a high amount of heat leaves the cooking space, even if the time spent away is short, the notification output unit outputs notification information to the audio output unit, and the audio output unit outputs the notification information by voice. Therefore, notification information can be provided regardless of the direction of the person's line of sight, such as with notification information using light or displayed on a display, enabling appropriate notification to the person performing cooking. Therefore, a heating and cooking system is configured that can appropriately notify the person cooking according to the heating status when the person cooking leaves the cooking space.

[0011] In addition to the above configuration, the judgment processing unit may perform a process of judging that the heating level is higher the greater the amount of heating heat in the heating unit, and when the heating cooker is in an automatic cooking mode in which heating is performed according to a preset routine, the judgment processing unit may set the heating level to the lowest regardless of the amount of heating heat.

[0012] According to this, when the heating cooker is heating in automatic cooking mode, the heating level is set to the lowest level, so if the person cooking leaves the cooking space, the alarm will be issued after a longer period of time has passed compared to cooking at a higher heating level, and the person cooking can, for example, do housework while cooking in automatic cooking mode without being notified of the alarm information.

[0013] In addition to the above configuration, when setting the time-up time, the judgment processing unit may set the time-up time to a shorter time if the heating heat amount in the heating unit is equal, the higher the temperature of the cooking appliance as the cooking status information.

[0014] This allows the time-up time to be set so that it is shorter if the temperature of the cooking appliance is higher, even if the amount of heat generated is the same, so that warning information can be issued early if the cooking appliance is at a high temperature.

[0015] In addition to the above configuration, the alarm output unit may repeatedly output the alarm information each time the time during which no person is detected by the human body detection unit exceeds the time-out time while heating continues in the heating unit, and may increase the volume of the alarm information as the number of repetitions increases.

[0016] According to this, when heating of the heating section continues, the notification information can be repeatedly output as sound, and the notification information is sound and is repeatedly output, and the volume of the notification information increases with this repetition, making it possible to reliably notify the person who was cooking.

[0017] In addition to the above configuration, the heating cooker has a heating control unit that enables heating by the heating unit to be stopped by a control signal transmitted via the communication unit, and the alarm output unit may repeatedly output the alarm information each time the time during which no person is detected by the human body detection unit exceeds the time-out time while heating continues in the heating unit, and may send a control signal via the communication unit to the heating control unit to stop heating by the heating unit when the number of repetitions reaches a predetermined number and the time during which no person is detected by the human body detection unit exceeds a predetermined time.

[0018] According to this, when the heating unit continues to heat, the alarm information can be repeatedly output as sound, and when the number of repetitions reaches a predetermined number and the time that the human body detection unit does not detect a person in the cooking space exceeds a predetermined time, the alarm output unit outputs a control signal to the heating control unit to stop heating, which causes the heating unit to stop heating and prevents excessive heating.

[Figure 5] 10 is a flowchart of a notification output routine. DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an embodiment of the cooking system according to the present invention will be described with reference to the drawings. The present embodiment is not limited to the following embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0021] [Basic configuration] As shown in Figure 1, cooking system A is configured with a cooking device 10 that is installed in kitchen 1 (cooking space) and heats a pot 14 (cooker) with a burner 12 (heating unit), an alarm device 20 that is installed in kitchen 1 and outputs information, and a communication unit 30 that transmits information between them.

[0022] In the case where the person cooking leaves the kitchen 1, the cooking system A acquires the cooking status of the cooker 10 via the communication unit 30 using the alarm device 20. When the alarm device 20 determines that the time during which no person is detected in the kitchen 1 while heating is being performed by the cooker 10 exceeds the alarm timer value T (see FIG. 5, an example of the time-out time), the alarm device 20 outputs alarm information (audio information) from the speaker 24 (an example of an audio output unit) of the alarm device 20. This audio information is information that notifies people in locations other than the kitchen 1 that cooking using the burner 12 in the cooker 10 in the kitchen 1 is continuing. Note that the speaker 24 need not be provided in the alarm device 20, but may also be provided in the kitchen 1 or a space separate from the kitchen 1.

[0023] Furthermore, in the cooking system A, the alarm 20 sets the heating level (see FIG. 4) based on cooking state information acquired from the cooker 10, and sets the alarm timer value T (time-out time) corresponding to the heating level. The heating level is set to a higher value the greater the amount of heat generated by the burner 12, and, given the same amount of heat, the higher the temperature of the pan 14. Therefore, the alarm timer value T is set to a shorter time the greater the amount of heat generated by the burner 12, and, given the same amount of heat, the higher the temperature of the pan 14.

[0024] This allows the heating and cooking system A to output warning information early if the cooking person leaves the kitchen 1 and the heating level is high, and guide the cooking person back to the kitchen 1 so that appropriate action can be taken.

[0025] In particular, if the person who was cooking does not return to the kitchen 1 before the stop timer value U (an example of a predetermined time) has elapsed after the alarm information has been output, the heating control unit 15a of the heating cooker 10 performs control to forcibly stop heating by the burner 12.

[0026] The following describes the details and control mode of this cooking system A. In this embodiment, the cooking system A is installed in a kitchen 1 of an ordinary home.

[0027] [Heating cooker] As shown in Fig. 1, cooking device 10 is configured as a gas stove with burner 12 (heating unit) on the top surface of case 11 and operation unit 13 for adjusting combustion on the front surface of case 11. Cooking device 10 achieves heating using (cooking appliances) such as pot 14 or frying pan by burning city gas or LP gas with burner 12.

[0028] As shown in FIGS. 1 and 2, the cooking appliance 10 includes a heating control unit 15 that enables control based on a program, such as a CPU (Central Processing Unit) or an MCU (Micro Controller Unit).

[0029] Cooking device 10 further includes a flow rate sensor 12FS that detects the amount of gas supplied to burner 12, and a temperature sensor 12TS that detects the temperature of an object to be heated, such as a pot 14 or a frying pan. Cooking device 10 also includes a mode button 16 that selects a heating mode, and an electromagnetic on-off valve 17 that enables the gas supply to burner 12 to be stopped.

[0030] The flow rate sensor 12FS makes it possible to determine the heating power by detecting the amount of gas supplied to the burner 12. Note that in order to detect the heating power during heating, it is also possible to use a flame sensor that optically detects the size and color of the flame produced by the burner 12 during combustion. Furthermore, in order to detect the heating power during heating, for example, a configuration may be used in which the gas flow rate is detected from the operating position of the operating unit 13.

[0031] Temperature sensor 12TS may be an infrared sensor that determines the temperature of the object to be heated, a sensor that measures radiant heat from the object to be heated, a sensor that detects the temperature of the air near the object to be heated, or a direct contact sensor. In this embodiment, direct contact temperature sensor 12TS is used, which has a temperature detection part that protrudes upward from the center of burner 12, and when pot 14 is placed on the trivet and the temperature detection part retracts downward, it comes into direct contact with the bottom of pot 14 to detect the temperature of the bottom of pot 14.

[0032] The mode button 16 allows the user to select between heating in a manual mode (manual cooking mode) and heating in an automatic mode (automatic cooking mode). When the manual mode is selected with the mode button 16, the cooking device 10 allows the user to adjust the heat level by manually operating the operation unit 13 when cooking with a pot 14, frying pan, or the like. In this embodiment, the amount of heat generated by the burner 12 can be adjusted in stages (e.g., eight stages) by operating (rotating) the operation unit 13, with the higher stage representing high heat and the lower stage representing low heat relative to the median value of the amount of heat within the adjustable range. The amount of heat generated by the burner 12 may also be adjusted continuously. The operation unit 13 can also be operated (pressed) to switch between ignition and extinguishing.

[0033] On the other hand, when the automatic mode is selected with the mode button 16, cooking is possible in which, for example, cooking rice using a pot 14 or steaming food using a steamer, heating is performed at a set temperature and heat for a set time, and the fire is automatically turned off after the cooking is completed.

[0034] When the automatic mode is selected, the cooking device 10 executes a plurality of heating routines corresponding to the cooking methods by the heating control unit 15a shown in Fig. 2. In this heating routine, the heating temperature, heating power, heating time, etc. are automatically set corresponding to the plurality of cooking methods.

[0035] [Alarm] The alarm device 20 is provided with a housing 21 and an alarm control unit 22 that enables control based on a program, such as a CPU (Central Processing Unit) or MCU (Micro Controller Unit).

[0036] 1 and 2, the alarm device 20 comprises a presence sensor 23 (human body detection unit) that detects the presence or absence of people in the kitchen 1, a notification output unit 22b that outputs notification information, and a speaker 24 (audio output unit) that outputs the notification information by voice. The notification output unit 22b outputs the notification information to the speaker 24.

[0037] The alarm device 20 is also configured to be able to notify people of the occurrence of abnormal conditions such as gas leaks, incomplete combustion, fires, etc. as notification information from the notification output section 22b. To this end, the alarm device 20 is equipped with a methane sensor that detects methane concentration, a CO sensor that detects carbon monoxide concentration, a heat sensor that detects indoor temperature, and a smoke sensor that detects smoke. Furthermore, the alarm device 20 can receive communication information such as weather information and shopping information sent from the alarm center via the communication network, and can also output warning information to alert people as alarm information from the alarm output unit 22b.

[0038] The presence sensor 23 may be a distance sensor using ultrasonic waves or microwaves, or a sensor that uses infrared rays to detect the presence or absence of a human body. Note that the presence sensor 23 may also be a sensor that uses a camera that takes pictures of the interior space of the kitchen 1 and processes the images taken by the camera to determine the presence or absence of a human.

[0039] [Communications Department] As shown in FIG. 2, the communication section 30 has a communication interface 31 connected to the heating control unit 15 and a communication cable 32 formed between the communication interface 31 connected to the notification control unit 22 .

[0040] The communication unit 30 is not limited to a configuration using a communication cable 32, but may use, for example, a communication standard that enables communication by radio waves, such as Bluetooth (registered trademark), or a wireless LAN.

[0041] [Control configuration] As shown in FIG. 2, heating control unit 15 includes heating control section 15a, heating power determination section 15b, temperature determination section 15c, and heating mode determination section 15d.

[0042] Each of the heating control unit 15a, the heating power determination unit 15b, the temperature determination unit 15c, and the heating mode determination unit 15d is configured by software, but may also include hardware in part.

[0043] Heating control unit 15a controls the overall combustion of gas in burner 12. In addition to controlling artificial heating through operation of operation unit 13, heating control unit 15a also controls heating at a set temperature and heat power for a set time when automatic mode is selected with mode button 16, as partially described above, and automatically extinguishes the flame after this heating. Heating control unit 15a is configured to be able to control the start (ignition) and stop (extinguishing) of gas combustion in burner 12, adjustment of the amount of heat generated by burner 12, and the like, based on operation of operation unit 13.

[0044] The heat power determination unit 15b determines the heat power (amount of heat generated per unit time: cooking state information) of the burner 12 based on the amount of operation of the operation unit 13. In other words, high or low heat can be selected depending on the amount of operation of the operation unit 13. Note that the heat power determination unit 15b may obtain the gas flow rate per unit time from the detection result of the flow rate sensor 12FS and determine the heat power from the amount of gas combusted by the burner 12. The temperature determination unit 15c determines the temperature (cooking state information) of the pot 14 or frying pan from the detection result of the temperature sensor 12TS. A high temperature is assumed to be a detected temperature above 100°C, and a low temperature is assumed to be a detected temperature below 100°C. Note that the cooking appliance 10 may be controlled to automatically return to low heat if the temperature becomes abnormally high after a set time has elapsed from high or high heat.

[0045] Heating mode determination unit 15d determines whether cooking device 10 is heating in manual mode or in automatic mode, based on the operation status of mode button 16. The determination result is also cooking state information.

[0046] The heating control unit 15a closes the on-off valve 17 based on the determination of the notification control unit 22, and realizes the stopping of combustion in the burner 12 (extinguishing).

[0047] As shown in FIG. 2, the notification control unit 22 includes a human body presence determining section 22a, a notification output section 22b, a determination processing section 22c, and a timer section 22d.

[0048] Each of the human body presence determining unit 22a, the notification output unit 22b, the determination processing unit 22c, and the timer unit 22d is configured by software, but may also include hardware in part.

[0049] The human presence determination unit 22a determines whether or not a person is present in the kitchen 1 based on the detection result of the presence sensor 23. The notification output unit 22b outputs audio notification information to the speaker 24 when the notification conditions are met. This notification information is intended to be an electronic sound, but human speech may also be used. The notification information is output in accordance with the control shown in the flowchart of FIG. 3.

[0050] Determination processor 22c determines the heating level based on information about the heating power (amount of heat) (low heat, high heat), information about the temperature of pot 14 (low temperature, high temperature), and information about the cooking mode (manual mode, automatic mode) transmitted via communication unit 30 from heating controller 15a, temperature determination unit 15c, and heating mode determination unit 15d of heating control unit 15. In this embodiment, four heating levels, L1 to L4, are set. In order to set the heating level in this manner, determination processor 22c has a table (not shown) for referencing the heating levels.

[0051] [Control mode] In this cooking system A, a program stored in the notification control unit 22 executes control according to the flowchart of Fig. 3. In this control, the notification control unit 22 acquires information about the cooking appliance 10, such as the combustion state of the burner 12, via the communication unit 30, thereby achieving control.

[0052] As shown in the flowchart of FIG. 3, in the cooking system A, the human presence determining unit 22a detects the presence of a person in the kitchen 1 based on detection by the presence sensor 23 (step #01).

[0053] Furthermore, even in a situation where the human presence determining unit 22a does not detect a person in the kitchen 1, if combustion of the burner 12 cannot be detected (No in step #02), control is performed not to proceed to the next step.

[0054] In contrast, when the human presence determination unit 22a does not detect a person in the kitchen 1 and determines in step #02 that the burner 12 of the cooking appliance 10 is burning (yes in step #02), the process proceeds to the cooking level determination routine (step #100), and after this process, the process proceeds to the notification output routine (step #200).

[0055] As shown in the flowchart of FIG. 4, in the cooking level determination routine (step #100), if the heating mode determined by heating mode determination unit 15d is "manual mode," the cooking level determination routine obtains the heating power (amount of heating heat) during combustion from heating power determination unit 15b, obtains the temperature of pot 14 (cooking appliance) from temperature determination unit 15c, and proceeds to processing to set the heating level (steps #101 to #103).

[0056] Also, if it is determined in step #101 that the heating mode is the "automatic mode," the process proceeds to step #103, where the heating level is set (steps #101 and #103).

[0057] In the process of setting the heating level (step #103), the heating level is set to one of L1 (level 1) to L4 (level 4) based on the acquired heating temperature and heat power. Specifically, high heat and strong heat are determined as L1 (level 1), low heat and strong heat are determined as L2 (level 2), and weak heat are determined as L3 (level 3). As explained above, in the heating level setting (step #103), automatic mode is determined as L4 (level 4).

[0058] Next, the alarm timer value T is set based on L1, L2, L3, and L4 (step #104). That is, the alarm timer value T is set to a larger value (length of time) in the order of L1, L2, L3, and L4. Therefore, when the high heat is set to L1 (level 1) and the temperature is high, the alarm timer value T is set to the shortest value.

[0059] The notification output routine (step #200) proceeds to a process (step #203) in which the timer unit 22d activates the notification timer (starts counting) and, when it determines that the count value of the notification timer has reached the notification timer value T (time has expired) (steps #201, #202).

[0060] In the process of outputting the notification information (step #203), a notification sound is output from the speaker 24 at set intervals, and the volume of the notification sound is increased as the number of times the notification sound is output increases.

[0061] After the notification output routine has completed the process of outputting the notification information, it returns to the main control shown in the flowchart of FIG.

[0062] As shown in this flowchart, after the processing of the notification output routine (step #200) is completed, the timer unit 22d activates the stop timer (starts counting, step #03), and if the human presence determination unit 22a determines that a person is present in the kitchen 1 based on the detection by the presence sensor 23 (yes in step #04), the process proceeds to step #01. At this time, the counting stops and the notification timer value T is cleared.

[0063] Furthermore, if the human presence / absence determination unit 22a determines in step #04 that there continues to be no one in the kitchen 1 (No in step #04), and determines that the count value of the stop timer has reached the stop timer value U (predetermined time) (time up) (yes in step #05), the heating control unit 15a stops the combustion of the burner 12 by closing the on-off valve 17, except for when the heating level is L4 (level 4) (step #06).

[0064] In this heating cooking system A, when the heating level is L4 (level 4), heating is performed in automatic mode, so if there is no one in kitchen 1, alarm information is output, but since the automatic mode automatically extinguishes the fire after the heating required by the automatic mode is performed, no forced extinguishing is performed.

[0065] In the cooking system A, the control mode may be set so that open information is not output when the heating level is L4 (level 4).

[0066] Furthermore, if the human presence determination unit 22a determines in step #04 that no one is present in the kitchen 1 (No in step #04), but does not determine that the count value of the stop timer has reached the stop timer value U (predetermined time) (time-up) (No in step #05), the process returns to the notification output routine (step #200). Thus, in the notification output routine (step #200), a process of outputting notification information (step #203) is performed each time the count value of the notification timer reaches the notification timer value T (steps #201 and #202). Then, when the number of repetitions reaches the predetermined number (the count value of the stop timer exceeds the stop timer value U) (step #5), combustion is stopped (step #06).

[0067] [Effects of the embodiment] In this way, in the heating cooking system A, when the person cooking leaves the kitchen 1 while heating is being performed continuously by the heating cooker 10 and the time during which no person is detected in the kitchen 1 exceeds the alarm timer value T, the alarm device 20 outputs alarm information (audio information) from the kitchen 1.

[0068] The alarm timer value T is set by the alarm device 20 to a value corresponding to the heating level (L1 to L4) that is set based on the acquired cooking state information. The heating level (L1 to L4) is set to a higher value as the heating power (amount of heating heat) increases, and when the heating power is the same, the higher the temperature, the higher the value is set, and the alarm timer value T is set to a shorter value as the heating level increases.

[0069] As a result, cooking system A outputs notification information early when no person is detected in kitchen 1 and the heating level is high. This audio notification information is output repeatedly at set intervals, making it easy to recognize people, and the volume of the notification information increases as the number of times it is output increases, ensuring reliable recognition of people. While the burner 12 continues to heat, the alarm information can be repeatedly output as sound, and the volume of the alarm information increases as the information is repeated, ensuring a reliable alarm to the person who was cooking. Furthermore, while the burner 12 continues to heat, the alarm information can be repeatedly output as sound, and if the number of repetitions reaches a predetermined number and the time during which no person is detected in the kitchen 1 by the human presence determination unit 22a exceeds a predetermined time, the alarm output unit 22b outputs a control signal to the heating control unit 15a to stop heating. This causes the burner 12 to stop heating, preventing excessive heating.

[0070] By outputting such notification information, the person who was cooking is guided to the kitchen 1 to take appropriate action, reducing cooking mistakes and making it possible to prevent excessive heating during cooking.

[0071] In particular, if the person who was cooking does not return to the kitchen 1 before the stop timer value U has elapsed after the notification information has been output, excessive heating is reliably prevented by controlling the cooking device 10 to forcibly stop heating.

[0072] [Another embodiment] The present invention may be configured as follows in addition to the above-described embodiments (common numbers and symbols as in the embodiments are used to designate components having the same functions as in the embodiments).

[0073] (a) The cooking appliance 10 may be an induction heating (IH) cooking heater. When an IH cooking heater is used, it is reasonable to set the processing mode so that the heating power determination unit 15b determines the heating power based on the electric power supplied for heating.

[0074] (b) The audio output of the alarm device 20 may be a combination of human speech and an alarm sound. The alarm device 20 may also be equipped with a display on which the content of the notification is displayed as text or images such as illustrations, and may also output audio information.

[0075] (c) The heating levels are not limited to the four levels L1 to L4 shown in the embodiment, and may be any number other than 4. As partially explained above, even if the cooking device 10 is controlled to automatically return to low heat when the temperature becomes abnormally high after a set time has elapsed in a high / high heat state, the heating level may be set according to the heat intensity in the high / high heat state.

[0076] Furthermore, the configurations disclosed in the above embodiments (including other embodiments, the same applies below) can be applied in combination with configurations disclosed in other embodiments, as long as no contradictions arise. Furthermore, the embodiments disclosed in this specification are examples, and the embodiments of the present invention are not limited to these, and can be modified as appropriate within the scope that does not deviate from the purpose of the present invention.
