JP 2019-22127 Publication

The cooking device management system of Patent Document 1 allows the user of the cooking device to control the cooking device using an external terminal when the user is away from the cooking device. However, if the user of the heating cooker is, for example, an elderly person, it may be difficult to control the heating cooker by operating an external terminal. If an abnormality occurs in the cooking device while the elderly person is away from the cooking device, a supervisor (e.g., a family member of the elderly person) who is in a separate location from the elderly person should remove the heating device. By controlling this, accidents caused by heating cookers can be prevented.

However, in principle, the heating cooker is operated by its user (for example, an elderly person), and if the heating cooker is allowed to be controlled by an administrator in an unauthorized manner, the convenience for the user decreases. Moreover, if the heating cooker can be controlled by the administrator, there is a risk that the safety consciousness of the user who operates the heating cooker will be lowered. In this specification, by allowing the administrator to control the heating cooker only under certain conditions, safety can be improved while ensuring convenience for the user of the heating cooker. Provides a heating cooker management system.

The cooking device management system disclosed in this specification includes a cooking device operated by a user, and an external terminal configured to be able to communicate with the cooking device and operated by an administrator. The heating cooker includes a heating section that heats an object to be cooked, a control section that controls the heating section based on control information including control details for the heating section, and a control section that detects the occurrence of an abnormality in the heating section. It is equipped with an anomaly detection section for detecting. This heating cooker further includes a transmitting unit that transmits abnormality related information including information regarding the abnormality detected by the abnormality detection unit to the external terminal, and the control content included in the control information from the external terminal. a receiving unit that receives control restriction information that limits the heating; and an operation interruption time that measures an operation interruption time that is a period during which the user's operation of the heating cooker is continuously interrupted while the heating unit is heating. It is equipped with a measuring section. The control unit detects an abnormality when the abnormality detection unit detects the occurrence of the abnormality and the operation interruption time is measured by the operation interruption time measurement unit before detecting the occurrence of the abnormality. If the pre-operation interruption time exceeds a predetermined threshold time, heating of the heating section is stopped. The transmitting unit transmits the abnormality-related information to the external terminal after the control unit stops heating the heating unit. When the external terminal receives the abnormality-related information from the transmitter, the external terminal transmits the control restriction information including restrictions on the control content to the receiver in accordance with instructions from the administrator. The control unit controls the heating unit with the control content limited by the control restriction information when the receiving unit receives the control restriction information. When the external terminal does not receive the abnormality related information from the transmitter, the external terminal does not transmit the control restriction information to the receiver.

In the cooking device management system according to the above aspect, heating of the heating unit is stopped when an abnormality has occurred and furthermore, the operation of the heating unit has been interrupted for a relatively long time. In such a case, there is a high possibility that the user of the cooking device is not near the cooking device, so the cooking device management system described above first stops heating the heating section to prevent accidents from occurring. To prevent. Thereafter, the transmitter transmits the abnormality-related information to the external terminal, thereby making it possible for the administrator to recognize that an abnormality has occurred. The administrator who recognizes the occurrence of an abnormality transmits control restriction information to the receiving section using an external terminal, and controls the heating section with the control content restricted by the control restriction information. With such a configuration, the administrator who recognizes the occurrence of an abnormality based on the abnormality-related information can restrict the control of the heating unit so that the abnormality does not occur thereafter. On the other hand, if the external terminal does not receive the abnormality-related information from the transmitter, it does not transmit the control restriction information to the receiver. That is, if the administrator does not receive abnormality-related information, the administrator cannot restrict the control content of the heating section. In this way, the heating cooker system disclosed in this specification allows the administrator to limit the control content of the heating cooker only under certain conditions. Thereby, safety can be improved while ensuring convenience for the user of the heating cooker.

In the heating cooker system according to the above aspect, the transmitter is configured to detect the occurrence of the abnormality within a predetermined time in a state where the pre-abnormal operation interruption time exceeds the predetermined threshold time. The abnormality related information may be transmitted to the external terminal when the frequency of detection exceeds a predetermined threshold frequency.

If an abnormality occurs frequently, the heating section stops heating, and the transmitter sends abnormality-related information to an external terminal, making the administrator aware that abnormalities are occurring frequently. can be done. Thereby, the administrator can limit the control content of the heating cooker based on the frequent occurrence of abnormalities.

Furthermore, in the heating cooking management system according to the above aspect, the limitations on the control content in the external terminal include a heating duration time that is a heating duration time of the heating unit, and a maximum value of the heating amount of the heating unit. The heating amount may relate to at least one of the maximum heating amount, and the start of heating in the heating section.

Thereby, the administrator can limit the control content according to the state of the user of the cooking device.

Further, in the cooking device management system according to the above aspect, the restriction on the control content in the external terminal is the control content regarding the abnormality included in the abnormality related information transmitted by the transmission unit to the external terminal. It may also be about only

Thereby, it is possible to permit restrictions only on the control contents related to the abnormality included in the abnormality-related information, without allowing the administrator to impose unnecessary restrictions on the control contents.

Furthermore, in the heating cooker management system according to the above aspect, the transmitter may transmit the abnormality-related information to the external terminal more than a predetermined threshold number of times, and then, when heating of the heating unit is started. , heating restart information indicating that the heating has been restarted may be transmitted to the external terminal. In that case, when the external terminal receives the heating restart information from the transmitting unit, the external terminal may transmit heating stop information for stopping the heating unit to the receiving unit in accordance with instructions from the administrator. . The control unit may stop heating the heating unit when the receiving unit receives the heating stop information. When the external terminal does not receive the heating restart information from the transmitter, the external terminal does not need to transmit the heating stop information to the receiver.

If the abnormality repeatedly occurs, it is presumed that the user of the heating cooker is not in a state where he or she can normally operate the heating cooker. In such a case, it is dangerous to allow the user of the cooking device to continue operating the cooking device. With the above-described configuration, when heating of the heating section is restarted after repeated abnormalities occur, the heating is stopped by the external terminal in accordance with instructions from the administrator, thereby improving safety. On the other hand, when the heating restart information is not received, convenience for the user of the heating cooker can be ensured by not having the administrator stop the heating.

The computer program according to the above aspect is configured to be able to communicate with a heating cooker operated by a user, and is used in an external terminal operated by an administrator. The heating cooker includes a heating section, a control section, an abnormality detection section, a transmitting section, a receiving section, and an operation interruption time measuring section. The heating section heats the food to be cooked. The control unit controls the heating unit based on control information including control details for the heating unit. The abnormality detection section detects occurrence of an abnormality in the heating section. The transmitter transmits abnormality related information including information regarding the abnormality detected by the abnormality detector to the external terminal. The receiving unit receives control restriction information that limits the control content included in the control information from the external terminal. The operation interruption time measuring unit measures an operation interruption time, which is a period during which the user's operation on the heating cooker is continuously interrupted while the heating unit is heating. The control unit detects an abnormality when the abnormality detection unit detects the occurrence of the abnormality and the operation interruption time is measured by the operation interruption time measurement unit before detecting the occurrence of the abnormality. If the pre-operation interruption time exceeds a predetermined threshold time, heating of the heating section is stopped. The transmitting unit transmits the abnormality related information to the external terminal after the control unit stops heating the heating unit. The computer program causes the external terminal to function as a terminal-side receiving section, a display section, an operation section, and a terminal-side transmitting section. The terminal-side receiving section receives the abnormality-related information from the transmitting section of the cooking device. The display unit displays information regarding the abnormality included in the abnormality related information. The operation unit causes the administrator to instruct restrictions on the control content based on the information regarding the abnormality displayed by the display unit. The terminal transmitting unit transmits the control restriction information including restrictions on the control content instructed by the administrator using the operating unit to the receiving unit of the cooking device. The control unit controls the heating unit with the control content limited by the control restriction information when the reception unit receives the control restriction information. The terminal side transmitting section does not transmit the control restriction information to the receiving section of the heating cooker when the terminal side receiving section does not receive the abnormality related information from the transmitting section of the heating cooker.

On the top plate 10u of the cooking device 10, a first stove 11a, a second stove 11b, a third stove 11c, and an exhaust port 17 communicating with the grill 28 are arranged. Further, a stove operation section 20 and a grill 28 are provided on the front surface 10f, which is the front side (that is, the right side in FIG. 1) of the cooking device 10. Further, on the left side of the front surface 10f of the heating cooker 10 in the drawing, there is provided a grill operation section for operating the grill burner 29a (see FIG. 2) in the grill 28, but its description will be omitted in this specification.

The first stove 11a includes a first stove burner 12a, a first sensor 14a, and a trivet 16a. A gas supply path (not shown) is connected to the first stove burner 12a. The gas supply path is provided with a flow rate adjustment valve (not shown) for adjusting the amount of gas supplied to the first stove burner 12a. The first stove burner 12a is ignited by operating an igniter (not shown) while gas is being supplied to the first stove burner 12a. The first stove 11a heats the food to be cooked, which is housed in a cooking container such as a pot or a frying pan placed above, by the first stove burner 12a that is lit. By adjusting the amount of gas supplied to the first stove burner 12a, the amount of heating of the first stove burner 12a can be adjusted. Further, by stopping the supply of gas to the first stove burner 12a, the first stove burner 12a is extinguished. In addition, the 2nd stove burner 12b with which the 2nd stove 11b is equipped, and the 3rd stove burner 12c with which the 3rd stove 11c is equipped also have the same structure as the 1st stove burner 12a.

The first sensor 14a detects the presence of a cooking container placed above the first stove 11a, and also detects the temperature of the cooking container heated by the first stove burner 12a of the first stove 11a. When the cooking container is placed on the first stove 11a, the first sensor 14a is pressed by the cooking container. When pressed by the cooking container, the first sensor 14a detects that the cooking container is placed above the first stove 11a. When no cooking container is placed on the first stove 11a, the first sensor 14a is not pressed. A thermocouple is disposed within the first sensor 14a, making it possible to measure the temperature of the cooking container that is in contact with the first sensor 14a. In addition, the 2nd sensor 14b with which the 2nd stove 11b is equipped, and the 3rd sensor 14c with which the 3rd stove 11c is equipped also have the same structure as the 1st sensor 14a. Further, the trivets 16a to 16c support the cooking containers placed above the respective stoves at a constant distance from the respective stove burners.

The stove operation section 20 includes a power switch 24 of the cooking device 10, a first heating amount operation section 20a, a second heating amount operation section 20b, a third heating amount operation section 20c, and a panel operation section 22.

The first heating amount operation section 20a corresponds to the first stove 11a. Similarly, the second heating amount operation section 20b corresponds to the second stove 11b, and the third heating amount operation section 20c corresponds to the third stove 11c. The first heating amount operation unit 20a is an alternate type switch for igniting and extinguishing the first stove burner 12a and adjusting the heating amount of the first stove burner 12a. The second heating amount operating section 20b and the third heating amount operating section 20c also have the same structure as the first heating amount operating section 20a.

The operating state of each stove burner (ie, the first stove burner 12a, the second stove burner 12b, and the third stove burner 12c) and the grill burner 29a (see FIG. 2) is displayed on the panel operation section 22. The user can use the panel operation unit 22 to set an extinguishing timer that extinguishes each stove burner and grill burner 29a after a predetermined period of time has elapsed. In addition, below, each stove burner and grill burner 29a may be collectively called all burners.

The heating cooker 10 houses a control device 40 therein. The control device 40 is a computer for automatically controlling the first stove 11a, the second stove 11b, the third stove 11c, and the grill burner 29a in the grill 28 (see FIG. 2).

The mobile terminal 30 is a terminal owned and operated by an administrator different from the user of the cooking device 10. Although details will be described later, the address, telephone number, etc. of the mobile terminal 30 can be registered in the cooking device 10 as the administrator's contact information. In addition, in this specification, in order to facilitate understanding, the user of the cooking device 10 may be simply referred to as a user, and the user of the mobile terminal 30 may be referred to as an administrator.

The control device 40 of the cooking device 10 can communicate with the mobile terminal 30 via the Internet 100. That is, the mobile terminal 30 is an external terminal configured to be able to communicate with the cooking device 10 via the Internet 100. Note that the cooking device 10 and the mobile terminal 30 may communicate with each other via an external network constituted by another public communication network or the like.

With reference to FIG. 2, the control configuration included in the cooking device management system 2 will be described. In addition, in FIG. 2, only the 1st stove burner 12a of the 1st stove 11a is described, and the description of the 2nd stove burner 12b and the 3rd stove burner 12c is abbreviate|omitted. Similarly, in FIG. 2, only the first sensor 14a of the first stove 11a is shown, and the description of the second sensor 14b and third sensor 14c is omitted. When the power switch 24 is turned on, the stove operation section 20, the panel operation section 22, the control device 40, etc. are activated.

The control device 40 includes a CPU (Central Processing Unit) that is a hardware processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The control device 40 also includes an external interface that is an interface for communicating with external equipment. When the stove operation unit 20 is operated, the control device 40 adjusts the thermal power of the first stove burner 12a based on the operation. The control device 40 is configured by, for example, an ECU (Electronic Control Unit).

The control device 40 develops a program stored in the ROM in advance into the RAM. The control device 40 uses a CPU to interpret and execute a program developed in the RAM to control each component. As a result, as shown in FIG. 2, the control device 40 is a computer equipped with a control section 40c, an abnormality detection section 40d, a storage section 40m, a transmission section 40s, a reception section 40r, and an operation interruption time measurement section 40i as software modules. Constructed as.

For example, when the first stove burner 12a is being heated, the control unit 40c controls the amount of heating of the first stove burner 12a by adjusting the amount of gas supplied to the first stove burner 12a. Further, the control unit 40c stops the heating of the first stove burner 12a by stopping the supply of gas to the first stove burner 12a. In this way, the control unit 40c controls the first stove burner 12a based on the control information.

The abnormality detection unit 40d detects the occurrence of an abnormality in all burners. For example, the abnormality detection unit 40d detects that the burner has forgotten to turn off when the continuous heating duration of all burners exceeds a predetermined upper limit time (for example, 2 hours). Further, the abnormality detection unit 40d detects that the heating of the first stove burner 12a has stopped (that is, the first stove burner 12a has stopped heating even though the first heating amount operation unit 20a has not been operated, as described with reference to FIG. 1). 12a misfires), it is detected that the food being heated has boiled over. Furthermore, when the temperature of the cooking container measured by the first sensor 14a described with reference to FIG. Detects the occurrence of dry cooking, burnt food, etc. Further, the abnormality detection unit 40d detects that the food to be cooked has burnt or the like even when the detected value of the internal temperature of the grill 28 has increased excessively. These abnormalities occur or become more likely to occur as the continuous heating duration time in each of all burners becomes longer.

The storage unit 40m stores the address and the like of the administrator's mobile terminal 30. For example, when the heating cooker 10 is purchased, the address, etc. of the administrator's mobile terminal 30 is stored in the storage unit 40m by communicating with the heating cooker 10 and the administrator's mobile terminal 30 using Bluetooth (registered trademark). be remembered. Note that the address and the like of the administrator's mobile terminal 30 may be stored in the storage unit 40m of the cooking device 10 by communicating via Wi-Fi (registered trademark). Furthermore, the address and the like of the administrator's mobile terminal 30 may be directly input into the cooking device 10. Further, abnormality information of a second embodiment, which will be described later with reference to FIG. 4, and abnormality-related information transmission history of a third embodiment, which will be described later with reference to FIG. 5, are also stored in the storage unit 40m.

The transmitting unit 40s transmits various information via the Internet 100 to the administrator's mobile terminal 30 stored in the storage unit 40m. The transmitting unit 40s transmits first abnormality-related information and second abnormality-related information including information regarding the abnormality detected by the abnormality detection unit 40d to the mobile terminal 30 via the Internet 100. Note that details of the first abnormality-related information and the second abnormality-related information will be described later.

The receiving unit 40r receives information transmitted from the mobile terminal 30 via the Internet 100. The receiving unit 40r receives control restriction information instructed by the administrator from the mobile terminal 30 via the Internet 100. Note that details of the control restriction information will be described later.

The operation interruption time measurement unit 40i measures an operation interruption time, which is the time during which the operation of the cooking device 10 is continuously interrupted after heating is started by any one of all the burners. The operation interruption time is the time during which the stove operation section 20 (see FIG. 1) and the grill operation section of the cooking device 10 are not continuously operated by the user. For example, when heating is started with the first stove burner 12a, the operation interruption time corresponds to the period from the start of heating until the user changes the heating amount of the first stove burner 12a using the first heating amount operation section 20a. do. In addition, when heating is started with the first stove burner 12a, if the user further starts heating with the second stove burner 12b, after the heating of the first stove burner 12a is started, the heating of the second stove burner 12b is The period until the start corresponds to the operation suspension time. That is, the operation interruption time is the time during which the user does not operate the cooking device 10, and if the operation interruption time is long, it is estimated that the user is not near the cooking device 10. Ru.

Next, the mobile terminal 30 will be explained. The mobile terminal 30 includes a CPU, RAM, ROM, etc., which are hardware processors, and is configured to perform various information processing based on programs and data. As a result, the mobile terminal 30 includes a display section 30d, an operation section 30о, a control section 30c, a terminal-side receiving section 30r, a terminal-side transmitting section 30s, and a storage section 30m. The display unit 30d is a display for displaying various information. The display section 30d may function as a so-called touch panel (that is, the operation section 30о). The operation unit 30о includes a plurality of keys. The administrator (that is, the user of the mobile terminal 30) can input various instructions into the mobile terminal 30 by operating the operation unit 30о. The mobile terminal 30 can be connected to the Internet 100 via a terminal-side receiving section 30r and a terminal-side transmitting section 30s. The terminal side receiving section 30r receives the above-described first abnormality related information and second abnormality related information from the transmitting section 40s of the cooking device 10. The terminal-side transmitter 30s transmits the control restriction information to the receiver 40r of the cooking device 10. The control unit 30c controls the operation of the mobile terminal 30. A management application 30a is stored in the storage unit 30m. The management application 30a is installed on the mobile terminal 30 from a server (not shown) on the Internet 100, for example. The management application 30a is an application for receiving various information regarding the cooking device 10 and transmitting various instructions to the cooking device 10.

With reference to FIG. 3, the process executed by the control device 40 of the cooking device management system 2 (see FIG. 1) of the first embodiment will be described. When the user of the cooking device 10 turns on the power switch 24 (see FIG. 1), the process shown in FIG. 3 is started. Note that in FIGS. 3 to 5, as an example, a case will be described in which the user is heating the food to be cooked using the first stove burner 12a (see FIG. 1). However, the control device 40 performs similar processing when heating the food with other stove burners and grill burners 29a.

When the user turns on the power switch 24 (see FIG. 1) and presses the first heating amount operation section 20a (see FIG. 1), the control device 40 starts heating the first stove burner 12a (step S2). After starting the first cooking stove burner 12a, the control device 40 starts measuring the operation interruption time Ti using the operation interruption time measurement unit 40i described with reference to FIG. 2 (step S4).

Next, the control device 40 monitors whether or not the user's operation of the cooking device 10 continues to be interrupted by the operation interruption time measuring unit 40i (step S6). Specifically, as described above, the operation interruption time measuring section 40i controls the operation of changing the heating amount of the first stove burner 12a by the first heating amount operation section 20a, and the heating of the other stove burners and the grill burner 29a. Monitor whether the user performs an operation to start, etc. If the user's operation described above is confirmed (step S6: NO), the control device 40 checks whether heating of all burners has stopped (step S10). If the heating of all the burners has stopped (step S10: YES), that is, if the user has stopped the heating of the first stove burner 12a before the occurrence of an abnormality, the control device 40 allows the user to restart any of all the burners. Wait until it starts heating.

For example, when the user performs an operation to change the heating amount of the first stove burner 12a (step S6: NO), the heating of the first stove burner 12a is not stopped. In this case (step S10: NO), the control device 40 determines that the interruption of the operation of the first stove burner 12a has ended, and resets the operation interruption time Ti that has been measured from the start of heating of the first stove burner 12a. (Step S12). After that, the control device 40 causes the operation interruption time measurement unit 40i to start measuring the operation interruption time Ti again (step S6). In this way, the control device 40 measures the status of the user's operation on the cooking device 10 based on the operation interruption time Ti, and determines that the user is near the cooking device 10 and that the cooking device 10 operates normally. 10 is being operated.

If the user does not operate the heating cooker 10 and the operation continues to be interrupted (step S6: YES), the control device 40 continues to measure the operation interruption time Ti by the operation interruption time measurement unit 40i. At the same time, the abnormality detection unit 40d monitors the occurrence of an abnormality (step S8). When the abnormality detection unit 40d cannot detect the occurrence of an abnormality (step S8: NO), the control device 40 causes the operation interruption time measurement unit 40i to continue measuring the operation interruption time Ti (step S6). When the abnormality detection section 40d detects the occurrence of an abnormality (step S8: YES), the control device 40 ends the measurement of the operation interruption time Ti by the operation interruption time measuring section 40i (step S14). As a result, the pre-abnormal operation interruption time Ta, which is the operation interruption time before the abnormality detection unit 40d detects the occurrence of an abnormality, is calculated.

Next, the control device 40 compares the pre-abnormal operation interruption time Ta and the threshold time Tth (step S16). The threshold time Tth is a time long enough to estimate that there is no user near the cooking device 10. The threshold time Tth is, for example, 30 minutes.

If the pre-abnormal operation interruption time Ta exceeds the threshold time Tth (step S16: YES), the control device 40 causes the control unit 40c described with reference to FIG. (step S18). The control device 40 stops heating the first stove burner 12a when the abnormality detection unit 40d detects an abnormality and the pre-abnormality operation interruption time Ta exceeds the threshold time Tth. Accordingly, when an abnormality occurs and it is estimated that there is no user near the heating cooker 10 (that is, when the user of the heating cooker 10 does not recognize the occurrence of the abnormality), the control device 40 ), the heating can be stopped first. After that, the control device 40 transmits the first abnormality related information to the administrator's mobile terminal 30 using the transmitter 40s described with reference to FIG. 2 (step S20).

Here, with reference to FIG. 6, the abnormality related information displayed on the administrator's mobile terminal 30 will be explained. When the transmitting unit 40s transmits the first abnormality-related information to the mobile terminal 30 in step S20 of FIG. 3, the mobile terminal 30 receives the first abnormality-related information by the terminal-side receiving unit 30r described with reference to FIG. . As a result, as shown in FIG. 6(A), the display unit 30d of the mobile terminal 30, which was explained with reference to FIG. Show what happened. Thereby, the administrator can recognize that the user of the cooking device 10 has caused the abnormality of forgetting to turn off the cooking device. Note that, as described above, the first abnormality related information includes abnormalities other than forgetting to turn off. The name of the abnormality displayed on the abnormality name display section 3a of the first abnormality related information is changed depending on the type of abnormality that has occurred in the first stove burner 12a (see FIG. 1).

When the administrator recognizes that an abnormality has occurred in the user's cooking device 10 and taps the OK button shown in FIG. 30d displays a control content selection screen. The control content selection screen includes a heating continuation time limiter 3c, a maximum heating amount limiter 3d, a heating start limiter 3e, and a restriction refusal button 3f. The heating continuation time limiter 3c can limit the heating continuation time when the user starts heating the object to be cooked again using any of the burners of the cooking device 10. For example, the administrator selects the heating continuation time limiter 3c and inputs the continuation time as "0.5 hour". Thereby, when the user starts heating again, for example, with the first cooking stove burner 12a, the heating is automatically stopped after 30 minutes. Even when the user heats the stove again using the second stove burner 12b (see FIG. 1), the heating is automatically stopped after 30 minutes.

Further, the maximum heating amount limiting section 3d can limit the maximum heating amount, which is the maximum value of the heating amount in the heating, when the user starts heating the food again using all the burners of the cooking device 10. can. For example, the administrator selects the maximum heating amount limiting section 3d and inputs "weak" as the maximum heating amount. As a result, when the user starts heating again, for example, with the third stove burner 12c (see FIG. 1), the heating is limited to a weak heating amount or less.

Furthermore, the heating start restriction section 3e restricts the user from starting heating of the object to be cooked in all the burners of the cooking device 10. As a result, even if the user attempts to heat up the grill burner 29a again using the grill burner 29a (see FIG. 1), the grill burner 29a will not be ignited. Furthermore, if the administrator does not want to select the control details, he or she may press the restriction refusal button 3f.

In this way, by including the heating continuation time limiter 3c, maximum heating amount limiter 3d, and heating start limiter 3e on the control content selection screen, the administrator can select a limit from among them according to the user's condition. The content can be selected and instructed to the control device 40. The restriction content selected by the administrator is transmitted as control restriction information to the receiving unit 40r of the control device 40 of the cooking device 10 by the terminal side transmitting unit 30s described with reference to FIG.

Here, with reference to FIG. 3 again, the processing executed by the control device 40 will be described. The control device 40 determines whether the receiving unit 40r has received the control restriction information selected (i.e., instructed) by the administrator on the restriction content selection screen shown in FIG. 7 (step S22). When the control restriction information is received (step S22: YES), the control device 40 checks whether heating of all burners has stopped (step S24). If the heating of all the burners has not stopped (step S24: NO), the heating of the burner that is currently being heated is stopped (step S28). As a result, if the user starts heating again with the first stove burner 12a or other stove burners and grill burners 29a after the control device 40 stops heating the first stove burner 12a in step S18, the corresponding Burner heating can be stopped.

If heating of all burners has been stopped in step S24 (step S24: YES), or after heating of all burners has been stopped in step S28, the control device 40 sets the control limit selected by the administrator. (Step S26). Thereby, the control unit 40c controls the subsequent operations of all burners in accordance with the administrator's instructions.

As shown in FIG. 8, when the control restrictions are set in step S26, the contents of the set control restrictions are displayed on the mobile terminal 30. Thereby, the administrator recognizes that the control limit specified by the administrator has been set (that is, in the example of FIG. 8, the heating duration time is limited to 0.5 hours). Furthermore, a restriction release button 3g is also displayed on the mobile terminal 30 at the same time as the details of the set control restriction. As a result, the administrator can check the user's situation afterwards, and can cancel the control restrictions if he or she determines that there is no problem.

Note that if the user attempts to use the cooking device 10 beyond the control limit while the control limit is set, a message "Used by administrator" will be displayed on the panel of the stove operation section 20 (see FIG. 1). "Restrictions have been placed." message is displayed. Furthermore, the user may be informed by voice that usage is restricted. Thereby, the user can recognize that control restrictions have been set for the cooking device 10 by the administrator. In that case, the user may contact the administrator directly and request the administrator to cancel the control restriction settings.

On the other hand, if the operation interruption time Ti is shorter than the threshold time Tth in step S16 (step S16: NO), even if an abnormality has occurred in the first stove burner 12a, the user can Since it is located near the cooking appliance 10, it is possible for the user to take action. Therefore, the control device 40 does not transmit the first abnormality related information to the administrator's mobile terminal 30.

Further, if the receiving unit 40r does not receive the control restriction information in step S22 (step S22: NO), the control device 40 waits for a predetermined period of time until receiving the control restriction information (step S23). If the predetermined time has not elapsed (step S23: NO), the control device 40 determines whether control restriction information has been received (step S22). If the control restriction information is not received even after the predetermined period of time has elapsed (step S23: YES), it is presumed that the administrator did not send the control restriction information. Finish the process. This allows control even in cases where the administrator did not instruct the setting of control restrictions, such as when the administrator who received the first abnormality-related information was able to confirm the user's situation by contacting the user directly. Limits can be prevented from being set.

As described above, in the cooking device management system 2 (see FIG. 1) of the first embodiment, an abnormality occurs in the first cooking stove burner 12a during heating, and the operation interruption time Ta before the abnormality is a threshold time. If it exceeds Tth, the first abnormality related information is transmitted to the administrator's mobile terminal 30. That is, when an abnormality has occurred and it is estimated that the user of the cooking device 10 is not present in the vicinity of the cooking device 10 for a long time, the heating cooking device management system 2 controls the administrator's mobile terminal 30. The first abnormality related information is transmitted to. Moreover, in the cooking device management system 2, when control restriction information is received from the administrator's mobile terminal 30, control restrictions are set. That is, the cooking device management system 2 allows the administrator to restrict control of the cooking device 10 only under the conditions described above. Thereby, the cooking device management system 2 can improve safety by recognizing control restrictions according to instructions from the administrator while ensuring convenience for the user of the cooking device 10.

(Second example)
With reference to FIG. 4, the process executed by the control device 40 of the cooking device management system 2 of the second embodiment will be described. The flow shown in FIG. 4 is a process added and executed between step S16 and step S22 of the flow of the first embodiment shown in FIG. When the pre-abnormal operation interruption time Ta exceeds the threshold time Tth (step S16: YES), the control device 40 of the second embodiment provides information regarding the abnormality detected by the abnormality detection unit 40d in step S8. The abnormality information is stored in the storage unit 40m (step S30). Here, the abnormality information includes the type of abnormality that has occurred, the frequency of abnormality occurrence, which is the number of times the abnormality has been detected within a predetermined period, and the like. Next, the control device 40 of the second embodiment calculates an abnormality occurrence frequency number Nw, which is the number of times an abnormality occurs within a predetermined time, from the abnormality information in the storage unit 40m (step S32). Then, the control device 40 of the second embodiment compares the abnormality occurrence frequency number Nw and the threshold frequency number Nth (step S34). The threshold frequency number Nth is the frequency of occurrence of an abnormality that is estimated to indicate that the user is not able to operate the cooking device 10 normally, and its value can be changed by the administrator. Note that the abnormality information may include the date and time of occurrence of the abnormality. In that case, the abnormality information may include the number of times an abnormality occurs instead of the frequency of abnormality occurrence described above. The control device 40 of the second embodiment may calculate the abnormality occurrence frequency number Nw using the date and time of abnormality occurrence and the number of times the abnormality has occurred.

If the abnormality occurrence frequency number Nw exceeds the threshold frequency number Nth (step S34: YES), the control device 40 of the second embodiment stops heating the first stove burner 12a (step S18). . Thereafter, the control device 40 of the second embodiment transmits the second abnormality-related information using the transmitter 40s instead of the first abnormality-related information described with reference to step S20 of FIG. 3 and FIG. 6(A). It is transmitted to the terminal 30 (step S36). The second abnormality related information includes not only the type of abnormality that has occurred in the heated first cooking stove burner 12a (see FIG. 1), but also the number of times that the abnormality has occurred within a predetermined period of time. When the mobile terminal 30 receives the second abnormality-related information, the display unit 30d indicates that forgetting to turn off has occurred three times within a predetermined period of time, as shown in the frequency of occurrence display unit 3b in FIG. 6(B). Display. Thereby, the administrator can recognize that the user of the cooking device 10 has forgotten to turn off the heating device 10 three times within a predetermined period of time. This allows the administrator to better understand the user's situation. As a result, the administrator can select control restriction instructions that are more suitable for the user's situation.

Note that the second abnormality related information may be transmitted to the mobile terminal 30 when the number of abnormality occurrence frequencies Nw of the same type exceeds the threshold frequency number Nth, or the second abnormality related information may be transmitted to the mobile terminal 30 when the abnormality occurrence frequency number Nw of the same type exceeds the threshold frequency number Nth, or the second abnormality related information may be transmitted to the mobile terminal 30 when the abnormality occurrence frequency number Nw of the same type exceeds the threshold frequency number Nth. It may be transmitted to the mobile terminal 30 when the number Nw exceeds the threshold frequency number Nth. In that case, the frequency of occurrence may be displayed on the mobile terminal 30 for each type of abnormality.

On the other hand, if the abnormality occurrence frequency number Nw is smaller than the threshold frequency number Nth (step S34: NO), even though the operation interruption time Ti is relatively long, an abnormality occurs in the first stove burner 12a during heating. The frequency of occurrence is low. In these cases, there is a high possibility that the user of the cooking device 10 normally recognizes that the first stove burner 12a is being heated. Therefore, in such a case, the control device 40 of the second embodiment first stops heating the first stove burner 12a (step S18), and then ends the process. That is, the control device 40 of the second embodiment does not transmit the second abnormality-related information to the administrator's mobile terminal 30, since there is no need to notify the administrator of information regarding the occurrence of an abnormality. In this way, in the cooking appliance management system 2 of the second embodiment, in addition to the pre-abnormal operation interruption time Ta of the first embodiment, when the abnormality occurrence frequency number Nw exceeds the threshold frequency number Nth, The second abnormality related information is transmitted to the mobile terminal 30. This reduces the number of times the second abnormality related information is transmitted, improving the convenience of the user of the heating cooker 10, and also notifying the administrator when abnormalities occur frequently. Can be done. Note that, if the abnormality occurrence frequency number Nw is smaller than the threshold frequency number Nth (step S34: NO), the control device 40 of the second embodiment terminates the process after stopping the heating of the first stove burner 12a. did. However, in the control device of the modification, after stopping the heating of the first stove burner 12a, the process of step S20 in FIG. 3 may be executed and the first abnormality related information may be transmitted to the mobile terminal 30.

(Third example)
With reference to FIG. 5, the process executed by the control device 40 of the cooking device management system 2 of the third embodiment will be described. The flow shown in FIG. 5 is a process added and executed between step S2 and step S4 of the flow of the first embodiment shown in FIG. In the cooking device management system 2 of the third embodiment, after transmitting the first abnormality-related information to the mobile terminal 30 in step S20 of FIG. 3, the storage unit 40m stores the abnormality-related information transmission history. Thereafter, in step S2, when heating of the first cooking stove burner 12a (see FIG. 1) is started, as shown in FIG. The number of transmissions Rs is calculated (step S40). Here, the number of times Rs of abnormality-related information transmission is the number of times the first abnormality-related information is transmitted to the mobile terminal 30 within a predetermined time period before heating all burners.

After calculating the number of abnormality-related information transmissions Rs in step S40, the control device 40 of the third embodiment compares the number of abnormality-related information transmissions Rs with the threshold number of times Rth (step S42). Here, the threshold number of times Rth is the number of times it is estimated that the user is unable to operate the heating cooker 10 normally when it occurs within a predetermined time, and the value can be changed by the administrator. .

If the number of abnormality-related information transmissions Rs exceeds the threshold number of times Rth (step S42: YES), the user starts heating again even though the user is not in a state where he or she can normally operate the cooking device 10. It is possible that you are trying to do so. In this case, the control device 40 of the third embodiment transmits heating restart information to the mobile terminal 30 (step S44). The mobile terminal 30 that received the heating restart information informs the administrator that the user (i.e., Mr. A) should try heating again using the heating cooker 10 (see FIG. 1), as shown in FIG. Notify you of your presence. The administrator transmits heating stop information to the cooking device 10 by tapping the heating stop instruction section 3h shown in FIG. Thereby, the control device 40 of the third embodiment determines whether the receiving unit 40r has received the heating stop information (step S46). If the control device 40 of the third embodiment has not received the heating stop information (step S46: NO), it waits for a predetermined period of time until it receives the heating stop information (step S47). If the predetermined time has not elapsed (step S47: NO), the control device 40 of the third embodiment determines whether heating stop information has been received again (step S46). If the control restriction information is not received even after the predetermined period of time has elapsed (step S47: YES), the control device 40 of the third embodiment determines that the heating stop information has not been sent from the administrator, and performs the steps shown in FIG. Processing from S4 is executed.

Similarly, if the administrator selects the heating stop refusal unit 3i shown in FIG. 9 and the receiving unit 40r does not receive heating stop information in step S46 (step S46: NO), the control device of the third embodiment 40 executes the processing from step S4 in FIG. Furthermore, even when the number of abnormality-related information transmissions Rs is smaller than the threshold number of times Rth (step S42: NO), the control device 40 of the third embodiment executes the processing from step S4 in FIG. 3. In these cases, it is considered that the administrator has determined that there is no need to stop heating, or that the number of times Rs of abnormality-related information transmission is small. The control device 40 of the third embodiment can ensure user convenience by not stopping heating in such a case.

When the receiving unit 40r receives the heating stop information (step S46: YES), the control device 40 of the third embodiment stops heating the burner heated by the user (step S48). Thereby, the administrator prevents the heating from being restarted by a user who is not in a state where he or she can normally operate the cooking device 10. Further, at this time, a message "Heating has been stopped by the administrator" is displayed on the panel of the stove operation unit 20 (see FIG. 1). Furthermore, the user may be informed by voice that the heating has been stopped. This allows the user to recognize that the administrator has stopped heating.

For example, if a user who has attempted to restart heating using the first cooking stove burner 12a but had the heating stopped by the administrator now attempts to restart heating using the second cooking stove burner 12b, the flow of FIG. 5 will be repeated. is executed, and the heating restart information is sent to the administrator's mobile terminal 30 again. With such a configuration, the administrator can recognize that the user is repeatedly attempting to restart heating.

(Correspondence) Each stove burner and grill burner 29a of the heating cooker 10 are examples of a "heating section". The mobile terminal 30 is an example of an "external terminal."

Although the embodiments have been described in detail above, these are merely illustrative and do not limit the scope of the claims. The techniques described in the claims include various modifications and changes to the specific examples illustrated above. Modifications of the above embodiment are listed below.

(Modification 1) The control content selection screen (see FIG. 7) of the above-described embodiment includes a heating duration limiter 3c, a maximum heating amount limiter 3d, and a heating start limiter 3e. . However, in a modified example, only information related to the abnormality included in the first abnormality related information may be displayed on the mobile terminal 30. For example, when the first abnormality related information includes an abnormality of "forgetting to turn off", the control content selection screen may include only the heating duration time limiter 3c. This makes it possible to limit the content of control restrictions granted to the administrator to those related to the abnormality that has occurred.

(Modification 2) The transmitter 40s of the control device 40 in the embodiment described above transmits the first and second abnormality related information to one mobile terminal 30, but in the modification, it transmits the first and second abnormality related information to a plurality of mobile terminals. These pieces of information may be transmitted at the same time. This allows a plurality of administrators to monitor the user's operations on the cooking device 10. Further, in that case, one of the plurality of administrators may be registered as the main administrator, and the control contents may be restricted preferentially based on instructions from the registered administrator.

(Modification 3) Furthermore, after the heating stop process has been executed by the administrator, the control device 40 of the third embodiment described above sends the administrator's mobile terminal 30 a message to restart the heating every time the user attempts to restart the heating. Information has been sent. Instead, in a modified example, once the heating stop process is executed, heating of all burners may be stopped for a predetermined period of time. In that case, as shown in FIG. 10, a display indicating that heating is being stopped may be displayed on the administrator's mobile terminal 30. Further, a heating stop release button 3j for releasing the heating may also be displayed together. Thereby, the number of times heating restart information is transmitted to the administrator's mobile terminal 30 can be reduced.

(Modification 4) The heating cooker 10 described above is a gas combustion type built-in stove that is used by being incorporated into a system kitchen. Instead, in a modified example, an electromagnetic induction cooking device (IH cooking device) may be used, or an electric heating device (IH cooking device) that heats the food by heating the built-in heating wire with electricity. For example, it may be an electric stove.

Although specific examples of the present invention have been described in detail above, these are merely illustrative and do not limit the scope of the claims. The techniques described in the claims include various modifications and changes to the specific examples illustrated above. The technical elements described in this specification or the drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims as filed. Furthermore, the techniques illustrated in this specification or the drawings can achieve multiple objectives simultaneously, and achieving one of the objectives has technical utility in itself.
