Description

[Technical field]

[0001] The present invention relates to a cooking system capable of displaying operating information of a cooking device that heats food to be cooked on a display unit of an information and communication terminal that is compatible with wireless communication with the cooking device, a cooking device used in the cooking system, and an application program for an information and communication terminal used in the cooking system. [Background technology]

[0002] Gas stoves, which heat food by burning a mixture of fuel gas and air in a burner, are a widely used example of a cooking appliance. It has been proposed to configure a cooking system for such gas stoves that can display operating information of the gas stove on the display of the smartphone by wirelessly connecting the gas stove to a communication terminal such as a smartphone.

[0003] For example, in the cooking system described in Patent Document 1, wireless two-way communication is established between a gas stove and a smartphone, and when transmission request information is sent from the smartphone to the gas stove, the gas stove responds by sending operation status information to the smartphone, and the operation status information received by the smartphone is displayed on the display. With this cooking system, even an inexpensive gas stove with poor human-machine interface (HMI) can provide operation status information to a user by using the user's smartphone. Bluetooth Low Energy (registered trademark) is known as a communication standard used for wireless connection between such gas stoves and smartphones. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-163537 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in a cooking system that uses wireless two-way communication between a gas stove and a smartphone as described above, a process called pairing (or bonding) is required to authenticate and remember the communication partner. This requires the gas stove to be equipped with an operation unit that the user operates when initiating pairing, and a display unit that displays the passcode. This is difficult to implement on inexpensive gas stoves that lack HMI in the first place, and even if a gas stove is equipped with an operation unit or display unit, these are often used for other functions, making pairing complicated and difficult to understand for inexperienced users.

[0006] This invention has been made in response to the above-mentioned problems in the conventional technology, and aims to provide a technology that enables operation information of a heating cooker to be displayed on the display unit of an information and communication terminal without the need for pairing between the heating cooker and an information and communication terminal of a heating cooking system. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the heating and cooking system of the present invention adopts the following configuration. <First aspect> A cooking system having a cooking device for heating food to be cooked and an information communication terminal capable of wireless communication with the cooking device, and capable of displaying operation information related to the operation of the cooking device on a display unit of the information communication terminal, The cooking appliance includes a transmitter capable of broadcasting a wireless signal including the operation information, The information communication terminal includes: a receiving unit capable of receiving the wireless signal transmitted from the transmitting unit; a storage unit that stores an application program for displaying the driving information on the display unit; A display control unit that controls the display of the display unit; Equipped with The display control unit, when the receiving unit receives the wireless signal from the transmitting unit in a state in which a dedicated screen is displayed on the display unit in accordance with the application program started by a user through a predetermined input, displays the driving information included in the wireless signal on the dedicated screen of the display unit. It is characterized by:

[0008] In the cooking system of the first aspect, the operation information is transmitted using a broadcast type wireless signal in which one-way transmission is performed from the transmitter on the cooking device to an unspecified number of other parties, and therefore, there is no need for a process of authenticating and remembering the communication partner (so-called pairing) to establish two-way communication between the cooking device and the information communication terminal, and the operation information of the cooking device can be simply displayed on a dedicated screen of the display unit and provided to the user by simply receiving the wireless signal at the receiver on the information communication terminal. Then, the operation information is displayed on the premise that the user starts an application program with a specified input and the dedicated screen is displayed on the display unit, so that the user's intention (whether or not the display of the operation information is required) can be confirmed based on whether the application program is started or not and whether or not the dedicated screen is displayed, and it is possible to prevent the operation information unnecessary for the user from being displayed arbitrarily on an unspecified number of information communication terminals capable of receiving wireless signals.

[0009] <Second aspect> In the heating and cooking system of the first aspect, The wireless signal transmitted from the transmitter includes identification information of the cooking appliance in addition to the operation information, The storage unit is capable of registering the identification information of the cooking device selected by a user, The display control unit displays the driving information on the dedicated screen of the display unit on the condition that the identification information registered in the storage unit matches the identification information included in the wireless signal received by the receiving unit. It is characterized by:

[0010] Although the operation information of the cooking appliance is transmitted to an unspecified number of parties by wireless signal, this operation information is only useful for the information communication terminal carried by the actual user of the cooking appliance, and is useless for other information communication terminals. Therefore, in the cooking system of the second aspect, in addition to starting the application program and displaying the dedicated screen, by making the matching of the identification information a condition, it is possible to check useful operation information on the information communication terminal side, and it is possible to prevent, for example, the inconvenience of the operation information of a cooking appliance of a neighboring house being displayed.

[0011] <Third aspect> In the heating and cooking system of the first or second aspect, The transmitting unit transmits the wireless signal a plurality of times regardless of whether the driving information has changed or not. It is characterized by:

[0012] Since the cooking appliance cannot determine whether the wireless signal transmitted by the broadcast method has been received by the information communication terminal, the cooking system of the third aspect transmits the wireless signal multiple times even if the operating information remains the same and the information is the same, thereby increasing the opportunities for reception at the information communication terminal and reducing missed reception.

[0013] <Fourth aspect> In the heating and cooking system of the third aspect, The transmitting unit transmits the wireless signal at a predetermined interval. It is characterized by:

[0014] In the heating and cooking system of the fourth aspect, by repeatedly transmitting a wireless signal at a predetermined interval, it is possible to provide an opportunity to periodically update the display of the operating information on the display unit of the information communication terminal as the operating information changes.

[0015] <Fifth aspect> In the heating and cooking system of the fourth aspect, As the predetermined interval, a first interval and a second interval shorter than the first interval are prepared, The transmission unit transmits the wireless signal at the first interval if the driving information does not change for a certain period of time, and transmits the wireless signal at the second interval for the certain period of time after the driving information changes. It is characterized by:

[0016] In the cooking system of the fifth aspect, if there is a change in the operation information of the cooker, a wireless signal including the changed operation information is transmitted at short intervals, so that the change in the operation information can be promptly and accurately transmitted to the information communication terminal and reflected in the display content on the display unit. On the other hand, if there is no change in the operation information of the cooker for a while, it is highly likely that the operation information has been transmitted to the information communication terminal by the previous transmission of the wireless signal, so that the power consumption of the cooker can be reduced by lengthening the interval of the transmission of the wireless signal to reduce the frequency.

[0017] <Sixth aspect> In any one of the heating and cooking systems according to the first to fifth aspects, The cooking device includes a detection unit that detects a predetermined special input, When the special input is detected by the detection unit, the transmission unit switches the content of the driving information included in the wireless signal from first information to second information different from the first information and transmits the second information. It is characterized by:

[0018] In the heating cooking system of the sixth aspect, when a special input is received, the content of the operating information displayed on the display unit of the information communication terminal switches from the first information to the second information. Therefore, for example, a worker providing maintenance services for a heating cooker can perform a special input that is not disclosed to general users, and the second information required for maintenance can be displayed on the display unit of the information communication terminal for confirmation.

[0019] In order to solve the above-mentioned problems, the cooking device of the present invention adopts the following configuration. A cooking device used in a cooking system capable of displaying operation information related to the operation of the cooking device for heating food on a display unit of an information communication terminal compatible with wireless communication with the cooking device, A transmitter capable of transmitting a radio signal including the driving information, The information communication terminal includes: a receiving unit capable of receiving the wireless signal transmitted from the transmitting unit; a storage unit that stores an application program for displaying the driving information on the display unit; A display control unit that controls the display of the display unit; There is a system in place, the display control unit, when the receiving unit receives the wireless signal from the transmitting unit in a state in which a dedicated screen is displayed on the display unit in accordance with the application program started by a user through a predetermined input, displays the driving information included in the wireless signal on the dedicated screen of the display unit; The transmitting unit transmits the wireless signal in a broadcast manner. It is characterized by:

[0020] According to the cooking device of the present invention, by transmitting the operation information using a broadcast type radio signal in which the transmitter transmits one-way to an unspecified number of parties, pairing with the information communication terminal is not required, and the operation information of the cooking device can be easily displayed on a dedicated screen of the display unit and provided to the user simply by receiving the radio signal at the receiver of the information communication terminal. Although the transmitter transmits a radio signal including the operation information to an unspecified number of parties, the operation information is displayed on the assumption that the user has started an application program with a specified input and the dedicated screen is displayed on the display unit of the information communication terminal, so that it is possible to prevent the operation information unnecessary for the user from being displayed arbitrarily on an unspecified number of information communication terminals capable of receiving the radio signal.

[0021] Furthermore, in order to solve the above-mentioned problems, the application program of the present invention employs the following configuration. An application program for a cooking system having a cooking device for heating food and an information communication terminal for wireless communication with the cooking device, the application program being stored on the information communication terminal and being activated by a predetermined input from a user, the application program being capable of displaying operating information relating to the operation of the cooking device on a display unit of the information communication terminal, a dedicated screen display step of displaying a dedicated screen on a display unit of the information communication terminal in a startup state due to the predetermined input; a receiving step of receiving a wireless signal including the operation information when the wireless signal is transmitted from the cooking appliance in a broadcast manner; a driving information display step of, when the wireless signal is received while the dedicated screen is displayed on the display unit, displaying the driving information included in the wireless signal on the dedicated screen of the display unit; The present invention is characterized by comprising:

[0022] According to the application program of the present invention, it is possible to provide the user with the operation information of the cooking appliance by simply displaying it on a dedicated screen of the display unit, without pairing the cooking appliance with the information communication terminal, by simply receiving a broadcast type wireless signal, in which the cooking appliance transmits one-way to an unspecified number of parties, on the information communication terminal side.The operation information is displayed on the premise that the user starts the application program with a specified input and the dedicated screen is displayed on the display unit, so that it is possible to prevent the operation information that is unnecessary for the user from being displayed arbitrarily on an unspecified number of information communication terminals that can receive the wireless signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] 1 is a perspective view showing the configuration of a cooking system 1 according to this embodiment. The cooking system 1 shown in the figure is composed of a gas stove 10 as an example of a cooking device that heats food to be cooked, and a smartphone 40 as an example of an information communication terminal compatible with wireless communication with the gas stove 10, and operation information related to the operation of the gas stove 10 can be displayed on a display unit 41 such as a liquid crystal display of the smartphone 40.

[0025] The illustrated gas stove 10 is a built-in type that is fitted into an open storage space in the worktop of a system kitchen (not shown), and is equipped with a box-shaped stove body 11 that is housed in the storage space, and a top plate 12 that is installed to cover the open top surface of the stove body 11.

[0026] A stove burner 13 that burns a mixture of fuel gas and air is mounted inside the stove body 11, and the upper part of the stove burner 13 protrudes from an insertion hole formed in the top plate 12. In the illustrated example, two stove burners 13a, 13b are arranged on the left and right. Trivets 14a, 14b for placing cooking containers such as pots for holding ingredients (food to be cooked) above the stove burners 13a, 13b are installed on the top plate 12, surrounding each stove burner 13a, 13b.

[0027] A grill 15 (not shown) for grilling food (food to be cooked) is built into the stove body 11. A grill door 15d is provided on the front of the stove body 11, and the front of the grill 15 can be opened and closed.

[0028] On the front of the stove body 11, to the right of the grill door 15d, there are provided a power switch 17 operated by the user when turning the gas stove 10 on and off, and stove operation buttons 18a, 18b that correspond to each of the two stove burners 13a, 13b and that the user operates when igniting, extinguishing, or adjusting the flame power. On the other hand, on the left of the grill door 15d, there is provided a grill operation button 19 that the user operates when igniting, extinguishing, or adjusting the flame power of the grill burner 15a, which burns a mixture of fuel gas and air as the heat source for the grill 15.

[0029] In the gas stove 10 of this embodiment, when a user presses an operation button (one of the stove operation buttons 18a, 18b and the grill operation button 19) backward, the pressed operation button 18a, 18b, 19 protrudes forward and the corresponding burner (one of the stove burners 13a, 13b and the grill burner 15a) is ignited and combustion begins. In addition, by rotating the protruding operation buttons 18a, 18b, 19, it is possible to adjust the flame power of the corresponding burners 13a, 13b, 15a. Then, by pushing the protruding operation buttons 18a, 18b, 19 backward, the corresponding burners 13a, 13b, 15a are extinguished.

[0030] 2 is an explanatory diagram showing a schematic diagram of the fuel gas supply path in the gas stove 10. The gas stove 10 of this embodiment is equipped with the above-mentioned three burners (burner burners 13a, 13b and grill burner 15a), and correspondingly, the gas passage 20 that supplies the fuel gas is branched into three. That is, it is divided into a left branch passage 21a corresponding to the left burner burner 13a, a right branch passage 21b corresponding to the right burner burner 13b, and a grill branch passage 21g corresponding to the grill burner 15a, and fuel gas is supplied to each of them.

[0031] The left branch passage 21a is provided with an on-off valve 22a for opening and closing the left branch passage 21a, a flow rate control valve 23a for controlling the flow rate of the fuel gas in the left branch passage 21a downstream of the on-off valve 22a, and a nozzle 24a for spraying the fuel gas from the end of the left branch passage 21a. When the on-off valve 22a is opened, the fuel gas is sprayed from the nozzle 24a at a flow rate according to the opening degree of the flow rate control valve 23a, and the mixed gas mixed with the primary air for combustion is supplied to the left stove burner 13a. This mixed gas is sprayed from the multiple flame ports of the left stove burner 13a, and the mixed gas starts to burn when a spark is generated by the ignition plug 25a, heating the ingredients (food to be cooked) in the cooking container above.

[0032] Thermocouple 26a is provided as a flame detector for detecting the combustion flame in left burner 13a, and it is possible to detect ignition and extinction based on the electromotive force of thermocouple 26a. In addition, pot bottom temperature sensor 27a is provided, which protrudes from the center of left burner 13a and abuts against the bottom surface of the cooking vessel above, and it is possible to detect the temperature of the cooking vessel.

[0033] Similarly, the right branch 21b is provided with an on-off valve 22b, a flow rate control valve 23b, and a nozzle 24b, and is provided with an ignition plug 25b, a thermocouple 26b, and a pan bottom temperature sensor 27b corresponding to the right stove burner 13b. The grill branch 21g is also provided with an on-off valve 22g, a flow rate control valve 23g, and a nozzle 24g. An ignition plug 25g and a thermocouple 26g corresponding to the grill burner 15a are provided, and a grill temperature sensor 28 is provided inside the grill 15, making it possible to detect the temperature inside the grill 15.

[0034] In the gas stove 10 of this embodiment, it is possible to burn one of the two burner burners 13a, 13b and the grill burner 15a alone, or to burn multiple burners simultaneously. In addition, each burner 13a, 13b, 15a can adjust the heat during combustion by controlling the opening (flow rate of fuel gas) of the corresponding flow rate control valve 23a, 23b, 23g.

[0035] 3 is a block diagram for controlling the combustion in the burners 13a, 13b, and 15a of the gas stove 10 and controlling the display of operation information on the display unit 41 of the smartphone 40. First, the gas stove 10 is equipped with a controller 30 that controls the entire gas stove 10, and the controller 30 is electrically connected to operation buttons 18a, 18b, and 19 corresponding to the two stove burners 13a and 13b and the grill burner 15a, respectively, opening and closing valves 22a, 22b, and 22g, flow rate control valves 23a, 23b, and 23g, ignition plugs 25a, 25b, and 25g, thermocouples 26a, 26b, and 26g, temperature sensors 27a, 27b, and 28, and the like.

[0036] When any of the operation buttons 18a, 18b, 19 is pressed and protrudes forward, the controller 30 opens the corresponding on-off valves 22a, 22b, 22g and causes the ignition plugs 25a, 25b, 25g to emit sparks. When any of the protruding operation buttons 18a, 18b, 19 is rotated, the controller 30 changes the opening degree of the corresponding flow rate control valves 23a, 23b, 23g in accordance with the amount of operation (rotation angle). When any of the protruding operation buttons 18a, 18b, 19 is pushed back backward, the controller 30 closes the corresponding on-off valves 22a, 22b, 22g.

[0037] In addition, when the corresponding thermocouple 26a, 26b, 26g does not detect ignition (detects extinguishing) even though any of the on-off valves 22a, 22b, 22g is in an open state, the controller 30 determines that an abnormality occurs in which ignition is not possible (ignition error) or that the fire has gone out during combustion (flame-out error), and closes the corresponding on-off valve 22a, 22b, 22g. Also, when the temperature detected by any of the temperature sensors 27a, 27b, 28 exceeds a specified temperature, the controller 30 determines that an abnormality occurs in which the temperature is too high (high temperature error), and closes the corresponding on-off valve 22a, 22b, 22g.

[0038] Furthermore, a transmitter 31 capable of transmitting a wireless signal including operation information of the gas stove 10 is connected to the controller 30. This transmitter 31 is configured to perform one-way transmission to an unspecified number of parties by broadcasting. In this embodiment, an advertisement signal of Bluetooth Low Energy (registered trademark) is used as such a wireless signal by broadcasting.

[0039] Meanwhile, the smartphone 40 includes, in addition to the display unit 41 such as the liquid crystal display described above, a receiving unit 42 capable of receiving a wireless signal (advertisement signal) transmitted from the transmitting unit 31 of the gas stove 10, a memory unit 43 that stores an application program (hereinafter referred to as an "operation information display application") for displaying the operation information of the gas stove 10 on the display unit 41, and a display control unit 44 that controls the display of the display unit 41. Note that these units are conceptually classified based on their functions, and each unit does not necessarily need to exist physically, and can be configured by various devices, electronic components, integrated circuits, computers, or a combination thereof.

[0040] The display unit 41 of this embodiment is equipped with a touch panel, and in accordance with an operation information display application started by a user through a predetermined input (for example, tapping an icon), the display control unit 44 displays a dedicated screen (hereinafter referred to as an "application screen") that displays operation information of the gas stove 10 on the display unit 41. In this state, when the receiving unit 42 receives an advertising signal from the transmitting unit 31, the operating information included in the advertising signal is displayed on the application screen of the display unit 41. Also, in the memory unit 43, it is possible to register identification information of the gas stove 10, which will be described later.

[0041] FIG. 4 is a flow chart showing a transmission control process executed by the controller 30 of the gas stove 10 to control the transmission of an advertising signal from the transmitter 31. This transmission control process is repeatedly executed at a predetermined cycle when the power supply of the gas stove 10 is turned on. When the transmission control process is started as shown in the figure, first, it is determined whether or not the maintenance flag is ON (STEP 1). In this embodiment, as the operation information of the gas stove 10, it is possible to transmit either operation state information related to the current operation state of the gas stove 10 or maintenance information related to the operation history to be confirmed in the maintenance of the gas stove 10, and the maintenance flag is a flag indicating that the maintenance mode is set to transmit the maintenance information. Note that a storage area for the maintenance flag is secured in the memory (not shown) of the controller 30. Also, the operation state information of this embodiment corresponds to the "first information" of the present invention, and the maintenance information of this embodiment corresponds to the "second information" of the present invention.

[0042] If the maintenance flag is OFF (STEP 1: no), it is next determined whether or not a special input has been detected (STEP 2). This special input is not disclosed to general users and is mainly performed by a maintenance service worker. In this embodiment, it is performed by switching a dip switch provided on a control board (not shown) built into the gas stove 10. The special input is an opportunity to switch from a normal use mode in which the current operating state information of the gas stove 10 is transmitted to a maintenance mode, so if the special input is not detected (STEP 2: no), the normal use mode remains. The above-mentioned dip switch in this embodiment corresponds to the "detection unit" of the present invention. The special input is not limited to switching the dip switch, and various modes such as an operation that is not usually performed by general users, for example, a combination of the operation of the operation buttons 18a, 18b, and 19 and the operation of an additional function button (not shown) can be adopted.

[0043] If it is in the normal use mode, it is then determined whether or not it is a certain period (30 seconds in this embodiment) after the operation state of the gas stove 10 has changed (STEP 3). In this embodiment, the advertising signal including the operation state information is repeatedly transmitted, and two types of transmission intervals are provided: a first interval (500 ms in this embodiment) and a second interval (100 ms in this embodiment) shorter than the first interval. If 30 seconds have passed since the change in the operation state of the gas stove 10 (STEP 3: no), the transmission interval is set to 500 ms (STEP 4), and if it is within 30 seconds since the change in the operation state of the gas stove 10 (STEP 3: yes), the transmission interval is set to 100 ms (STEP 5). It should be noted that the operation state is considered to have changed immediately after the power of the gas stove 10 is turned on, and if it is within 30 seconds, the transmission interval is set to 100 ms.

[0044] After setting the transmission interval in this way, it is determined whether the set interval (100 ms or 500 ms) has elapsed since the previous transmission of the advertising signal (STEP 6). If the set interval has not yet elapsed since the previous transmission of the advertising signal (STEP 6: no), the advertising signal is not transmitted and the process returns to STEP 1 in the transmission control process of FIG.

[0045] On the other hand, if the set interval has passed since the previous transmission of the advertising signal (STEP 6: yes), the operating status information is acquired (STEP 7). Note that, when the gas stove 10 is turned on and the advertising signal is transmitted for the first time, it is assumed that the set interval (100 ms) has already passed since the previous transmission. As described above, the operating status information is related to the current operating status of the gas stove 10, and for example, whether each burner 13a, 13b, 15a is burning or stopped, whether an error has occurred, and the contents of the error that has occurred are acquired.

[0046] Furthermore, the acquired operating state information is compared with the previous operating state information to determine whether or not there is a change in the operating state of the gas stove 10 (STEP 8). If there is a change in the operating state of the gas stove 10 (STEP 8: yes), the time measurement is started again starting from the change in the operating state (STEP 9). In the process of STEP 3 described above, based on this time measurement, it is determined whether or not it is a certain period (30 seconds) after the operating state has changed. On the other hand, if there is no change in the operating state of the gas stove 10 (STEP 8: no), the process of STEP 9 is omitted. After that, when an advertising signal including the acquired operating state information is transmitted (STEP 10), the process returns to STEP 1 in the transmission control process of FIG. 4. In addition to the operating information of the gas stove 10, the advertising signal of this embodiment includes identification information such as the serial number and address of the gas stove 10.

[0047] The above describes the process when the maintenance flag is OFF (STEP 1: no) and no special input is detected (STEP 2: no), i.e., the process is executed in the normal use mode. In contrast, if a special input is detected in the determination in STEP 2 (STEP 2: yes), the maintenance flag is turned ON to set the maintenance mode (STEP 11). The ON maintenance flag returns to the OFF state when the power to the gas stove 10 is turned OFF.

[0048] When the maintenance flag is thus turned ON, or when the determination in STEP 1 indicates that the maintenance flag is already ON (STEP 1: yes), it is then determined whether or not a predetermined interval (100 ms in this embodiment) has elapsed since the previous transmission of the advertising signal (STEP 12). In this embodiment, the advertising signal including the maintenance information is repeatedly transmitted at a predetermined interval. Therefore, if 100 ms has not yet elapsed since the previous transmission of the advertising signal (STEP 12: no), the advertising signal is not transmitted, and the process returns to STEP 1 in the transmission control process in FIG. 4.

[0049] On the other hand, if 100 ms has passed since the previous transmission of the advertising signal (STEP 12: yes), the maintenance information is acquired (STEP 13). Note that, when the advertising signal is transmitted for the first time after the maintenance flag is turned ON, it is assumed that 100 ms has already passed since the previous transmission. In addition, as the maintenance information, for example, the number of combustions in each burner 13a, 13b, 15a, the history of error occurrence, the contents of the error that occurred, etc. are acquired. Such maintenance information is stored in the memory (not shown) of the controller 30. Then, when the advertising signal including the acquired maintenance information is transmitted (STEP 14), the process returns to STEP 1 in the transmission control process of FIG. 4.

[0050] 5 is a flowchart showing a display control process executed by the display control unit 44 of the smartphone 40 to control the display of the operation information of the gas stove 10 on the display unit 41. This display control process is executed repeatedly at a predetermined cycle according to the operation information display application when the user starts the operation information display application by a predetermined input (for example, tapping an icon). When the display control process is started as shown in the figure, it is first determined whether or not a dedicated application screen for displaying the operation information of the gas stove 10 is being displayed on the display unit 41 (STEP 20). Even if the operation information display application is running, the home screen of the smartphone 40 or another screen corresponding to another application program running at the same time may be displayed on the display unit 41, and the application may be running in the so-called background.

[0051] If the application screen is not displayed on the display unit 41 (STEP 20: no), it is next determined whether the display condition for the application screen is satisfied (STEP 21). The display condition may include a user selecting the driving information display application from a list of application programs running in the background, or a user making a predetermined input (tapping an icon) to start the driving information display application. If the display condition is not satisfied (STEP 21: no), the process returns to STEP 20 in the display control process of FIG. 5.

[0052] On the other hand, if the display condition for the application screen is met (STEP 21: yes), the application screen is displayed on the display unit 41 (STEP 22). In this embodiment, the condition is that the application screen is displayed on the display unit 41, and the receiver unit 42 is set to a scan state in which the advertising signal can be received. Since power consumption increases during the scan state, when the application screen is not displayed on the display unit 41 (when the driving information display application is running in the background), the power consumption of the smartphone 40 can be reduced by canceling the scan state.

[0053] In this way, the application screen is displayed on the display unit 41, or if it is determined in STEP 20 that the application screen is already being displayed on the display unit 41 (STEP 20: yes), it is then determined whether or not an operation to register the identification information of the gas stove 10 has been performed (STEP 23). In this embodiment, identification information such as the serial number and address of the gas stove 10 is written on the top plate 12, etc., and the identification information of the gas stove 10 selected by the user (for use by the user) is registered in advance in the smartphone 40. As a registration operation, for example, the user directly inputs the serial number and address on a registration screen displayed on the display unit 41. Alternatively, a two-dimensional code containing the serial number and address may be displayed on the top plate 12, etc., and the user may read the two-dimensional code with a camera mounted on the smartphone 40.

[0054] Then, if the registration operation of the identification information of the gas stove 10 has been performed (STEP 23: yes), the identification information is registered in the storage unit 43 (STEP 24). On the other hand, if the registration operation has not been performed (STEP 23: no), the processing of STEP 24 is omitted. Note that if the identification information of the gas stove 10 has already been registered, there is no need to perform the registration operation again.

[0055] Thereafter, it is determined whether or not an advertising signal transmitted from the transmitting unit 31 of the gas stove 10 has been received (STEP 25). As described above, if the application screen is displayed on the display unit 41, the receiving unit 42 is in a scanning state in which the advertising signal can be received. If an advertising signal has not been received (STEP 25: no), the process returns to STEP 20 in the display control process of FIG.

[0056] On the other hand, if an advertising signal is received (STEP 25: yes), it is determined whether the identification information of the gas stove 10 registered in the memory unit 43 matches the identification information of the gas stove 10 included in the received advertising signal (STEP 26). As described above, the advertising signal transmitted from the transmitter 31 of the gas stove 10 includes identification information in addition to the operation information of the gas stove 10. For example, if the received advertising signal is not the gas stove 10 selected by the user but is transmitted from the gas stove 10 of a neighboring house, and the identification information does not match (STEP 26: no), the operation information included in the advertising signal is not adopted and the process returns to STEP 20 in the display control process of FIG. 5.

[0057] On the other hand, if the identification information of the gas stove 10 matches (STEP 26: yes), it is determined whether the operation information of the gas stove 10 included in the received advertising signal is maintenance information (STEP 27). As described above, the operation information of the gas stove 10 includes operation status information on the current operation status of the gas stove 10 and maintenance information on the operation history to be checked during maintenance of the gas stove 10. If the gas stove 10 is in normal use mode, operation status information is transmitted, and if the gas stove 10 is in maintenance mode, maintenance information is transmitted.

[0058] If the operation information of the gas stove 10 included in the received advertising signal is operation status information (STEP 27: no), the operation status information included in the advertising signal is displayed on the application screen of the display unit 41 (STEP 28), and the process returns to STEP 20 in the display control process of FIG. 5. On the other hand, if the operation information of the gas stove 10 included in the received advertising signal is maintenance information (STEP 27: yes), the application screen of the display unit 41 is changed to one for maintenance (STEP 29). In this embodiment, since the display contents of the application screen are different between the normal use mode (operation status information) and the maintenance mode (maintenance information), the maintenance information included in the advertising signal is displayed on the application screen for maintenance (STEP 30). Then, the process returns to STEP 20 in the display control process of FIG. 5.

[0059] 6 is a time chart showing an example of displaying the operation information of the gas stove 10 on the display unit 41 of the smartphone 40. In the figure, the left side shows the processing in the gas stove 10, and the right side shows the processing in the smartphone 40. First, on the smartphone 40 side, a dedicated application screen is displayed on the display unit 41 according to the operation information display application started in response to a predetermined input (tapping an icon) by the user, and the receiver unit 42 enters a scanning state in which it can receive an advertising signal. Also, when the user performs an operation to register the identification information of the gas stove 10, the identification information is registered.

[0060] On the other hand, when the gas stove 10 is turned on, an advertising signal including operating state information A relating to the current operating state of the gas stove 10 is transmitted from the transmitting unit 31. As described above, the advertising signal is a broadcast type wireless signal transmitted in one direction to an unspecified number of parties. The smartphone 40 receives this advertising signal at the receiving unit 42, and after confirming that the identification information of the gas stove 10 included in the advertising signal matches the registered identification information, displays the operating state information A included in the advertising signal on the application screen of the display unit 41.

[0061] In addition, the gas stove 10 is configured to transmit the advertising signal including the operating state information A from the transmission unit 31 multiple times, not just once, and repeatedly at intervals of 100 ms. In this embodiment, bidirectional communication is not established between the gas stove 10 and the smartphone 40, and the gas stove 10 side cannot know whether the transmitted advertising signal has been received by the smartphone 40 side. Therefore, by transmitting the advertising signal multiple times, the smartphone 40 side can increase the chances of receiving the signal, thereby suppressing missed reception. Note that the smartphone 40 side may receive the advertising signal including the same operating state information A multiple times, but of course, there is no change in the display content on the application screen of the display unit 41.

[0062] Then, when 30 seconds have passed without any change in the operating state of gas stove 10, the interval for transmitting the advertising signal is increased from 100 ms to 500 ms. If there is no change in the operating state of gas stove 10 for a certain period of time (here, 30 seconds), it is highly likely that the operating state has been conveyed to smartphone 40 by the previous transmission of the advertising signal, so by lengthening the interval for transmitting the advertising signal to reduce the frequency, it is possible to reduce the power consumption of gas stove 10.

[0063] Thereafter, when the operating state changes on the gas stove 10 side, the advertising signal is switched to operating state information B after the change and transmitted from the transmitting unit 31. Then, on the smartphone 40 side, as the receiving unit 42 receives the advertising signal including the operating state information B, the display content on the application screen of the display unit 41 is updated to operating state information B.

[0064] In addition, for 30 seconds after the change in the operating state of the gas stove 10, the interval for transmitting the advertising signal is returned to 100 ms, and the transmission is repeated. By transmitting the advertising signal including the changed operating state information B at short intervals in this manner, the change in the operating state can be quickly and accurately conveyed to the smartphone 40, and reflected in the display content on the application screen of the display unit 41. Then, when 30 seconds have passed since the change in the operating state of the gas stove 10, the interval for transmitting the advertising signal is expanded again to 500 ms.

[0065] Furthermore, when a special input that is not disclosed to general users is made on the gas stove 10 side by a maintenance service worker or the like, the normal use mode is switched to a maintenance mode, and an advertising signal including maintenance information related to the operation history of the gas stove 10 is transmitted from the transmitting unit 31. On the smartphone 40 side that receives this advertising signal at the receiving unit 42, the application screen on the display unit 41 is changed to one for maintenance, and the maintenance information included in the advertising signal is displayed on the application screen for maintenance.

[0066] In addition, the transmitting unit 31 of the gas stove 10 transmits the advertising signal including the maintenance information not just once, but multiple times, and transmits it repeatedly at intervals of 100 ms.

[0067] FIG. 7 is an explanatory diagram showing an example of a display on the display unit 41 of the smartphone 40 that has received an advertising signal including operating state information. As an example, FIG. 7(a) conceptually shows the data structure of an advertising signal including operating state information A. As shown in the figure, the advertising signal first includes transmission mode information of the gas stove 10 (normal use mode or maintenance mode), and operating state information A regarding the current operating state of the gas stove 10 is transmitted in the "normal use mode". Next, the serial number is included as identification information of the gas stove 10. In the illustrated example, the serial number is expressed as a six-digit number "12-3456", and the same serial number is written on the top plate 12, etc.

[0068] Next, the operation status information A includes the operation status of the three burners (left burner 13a, right burner 13b, and grill burner 15a) and the contents of the error that has occurred. In the illustrated example, the left burner 13a is stopped, and the right burner 13b and grill burner 15a are burning. In addition, no error has occurred in any of the three burners 13a, 13b, and 15a. In addition, the advertising signal can transmit other data as long as it is up to 31 bytes in one transmission.

[0069] FIG. 7(b) shows an example of a display on the display unit 41 of the smartphone 40 that has received the advertising signal of FIG. 7(a). The display unit 41 displays an application screen for the normal use mode, and the upper part of the screen shows the serial number of the registered gas stove 10. As described above, on condition that the registered serial number matches the serial number included in the received advertising signal, the operating information included in the advertising signal (here, operating state information A) is displayed on the application screen of the display unit 41. Note that an edit button is provided on the application screen, and the user can tap this edit button to newly register or change the serial number of the gas stove 10 that he or she uses.

[0070] In addition, the illustrated application screen shows an illustration of the gas stove 10, and the parts of the illustration that correspond to the right burner 13b and grill burner 15a, which are burning, are labeled "burning" based on the operating state information A. On the other hand, no label is attached to the part of the illustration that corresponds to the left burner 13a, which is stopped. By showing the operating state of each burner 13a, 13b, 15a using an illustration that resembles the gas stove 10 in this way, it is easy for the user to understand.

[0071] After that, when the operating state of the gas stove 10 changes, an advertising signal including the changed operating state information B is transmitted as shown in Fig. 7(c). In the illustrated operating state information B, the right stove burner 13b has stopped due to an error, and the error is a high temperature error (the temperature detected by the pot bottom temperature sensor 27b exceeds the specified temperature). There is no change in the left stove burner 13a and the grill burner 15a.

[0072] Then, on the display unit 41 of the smartphone 40 that has received the advertising signal including the changed operating state information B, as shown in Fig. 7(d), a "high temperature error stopped" label is attached to the location corresponding to the right burner 13b of the illustration imitating the gas stove 10. It is desirable for the label indicating the occurrence of this error to have a different background and text color from the normal "burning" label; for example, if the background of the "burning" label is white, the background of the "high temperature error stopped" label is red to draw the user's attention.

[0073] Fig. 8 is an explanatory diagram showing an example of a display on the display unit 41 of the smartphone 40 that has received an advertising signal including maintenance information. Fig. 8(a) conceptually illustrates the data structure of an advertising signal including maintenance information. The advertising signal including maintenance information also includes transmission mode information of the gas stove 10 and a serial number as identification information, as in Fig. 7(a), and maintenance information related to the operating history to be checked during maintenance of the gas stove 10 is transmitted in "maintenance mode."

[0074] Next, the maintenance information includes the number of combustions performed on the three burners (left burner 13a, right burner 13b, and grill burner 15a) and the history of errors that have occurred. In the illustrated example, the number of combustions performed on the left burner 13a is "100 times", the number of combustions performed on the right burner 13b is "200 times", and the number of combustions performed on the grill burner 15a is "300 times". In addition, the left burner 13a has a history of ignition errors (an abnormality in which ignition cannot be detected by the thermocouple 26b at the time of ignition), the right burner 13b has a history of high temperature errors (an abnormality in which the temperature detected by the pot bottom temperature sensor 27b exceeds a specified temperature), and the grill burner 15a has no history of errors. The maintenance information may also include the cumulative combustion time of each burner 13a, 13b, and 15a. The error occurrence history may be configured to display a history of multiple errors, for example, by displaying the past 10 errors in chronological order starting from the most recent error.

[0075] 8(b) and 8(c) show examples of displays on the display unit 41 of the smartphone 40 that has received the advertising signal of FIG. 8(a). In this case, it is assumed that the smartphone 40 is carried by a worker or the like who provides maintenance services for the gas stove 10. The display unit 41 displays a maintenance application screen, and as shown in the figure, a number of combustions button and an error history button are provided below a display field for the serial number of the registered gas stove 10.

[0076] When the burn count button is tapped, the burn count is displayed on the app screen based on the maintenance information. That is, in the example shown in Fig. 8(b), in the illustration of the gas stove 10, the part corresponding to the left burner 13a is labeled "100 times", the part corresponding to the right burner 13b is labeled "200 times", and the part corresponding to the grill burner 15a is labeled "300 times".

[0077] On the other hand, when the error history button is tapped, the display on the app screen switches to the error history based on the maintenance information. That is, in the example shown in Fig. 8(c), in the illustration of the gas stove 10, the part corresponding to the left burner 13a, which has a history of ignition errors, is labeled "ignition error," and the part corresponding to the right burner 13b, which has a history of high temperature errors, is labeled "high temperature error." Note that no label is attached to the part corresponding to the grill burner 15a, which has no history of errors.

[0078] As described above, in the heating and cooking system 1 of this embodiment, an advertising signal (broadcast type wireless signal) including operating status information is transmitted from the transmitting unit 31 on the gas stove 10 side, and on the smartphone 40 side, when the receiving unit 42 receives the advertising signal while a dedicated app screen is displayed on the display unit 41 in accordance with an operating information display app that the user has activated by a specified input (tapping an icon), the operating status information included in the advertising signal is displayed on the app screen of the display unit 41.

[0079] In this way, by transmitting the operating state information using the advertising signal that transmits one-way from the transmitting unit 31 on the gas stove 10 side to an unspecified number of other parties, a process of authenticating and remembering the communication partner to establish two-way communication between the gas stove 10 and the smartphone 40 (so-called pairing) is not required, and the operating state information of the gas stove 10 can be easily displayed on the application screen of the display unit 41 and provided to the user simply by receiving the advertising signal at the receiving unit 42 on the smartphone 40 side. Then, the operating state information is displayed on the premise that the user starts the operating information display application with a specified input and a dedicated application screen is displayed on the display unit 41, so that the user's intention (whether or not the display of the operating state information is necessary) can be confirmed based on whether the operating information display application is started or not and whether or not the application screen is displayed, and it is possible to prevent the operating state information that is unnecessary for the user from being displayed arbitrarily on an unspecified number of smartphones 40 that can receive the advertising signal.

[0080] Furthermore, in the cooking system 1 of this embodiment, the advertising signal transmitted from the transmitter 31 on the gas stove 10 side contains the identification information (serial number) of the gas stove 10 in addition to the operating state information, and the identification information of the gas stove 10 selected by the user can be registered in the memory unit 43 on the smartphone 40 side. Then, on condition that the identification information of the registered gas stove 10 matches the identification information of the gas stove 10 contained in the received advertising signal, the operating state information contained in the advertising signal is displayed on the application screen of the display unit 41.

[0081] Although the operating status information of the gas stove 10 is transmitted to an unspecified number of parties by the advertising signal, this operating status information is only useful for the smartphone 40 owned by the actual user of the gas stove 10, and is not necessary for other smartphones 40. Therefore, by setting a condition of matching the identification information of the gas stove 10 in addition to starting the operating information display app or displaying a dedicated app screen, useful operating status information can be confirmed on the smartphone 40 side, and it is possible to prevent the inconvenience of displaying, for example, the operating status information of a neighboring gas stove 10.

[0082] In addition, in the cooking system 1 of this embodiment, the advertising signal is transmitted multiple times regardless of whether or not there is a change in the operating state information of the gas stove 10. As described above, the gas stove 10 cannot know whether the transmitted advertising signal has been received by the smartphone 40, so by transmitting the advertising signal multiple times even for the same operating state information, it is possible to increase the chances of reception by the smartphone 40 and prevent missed reception.

[0083] In particular, in the cooking system 1 of this embodiment, the advertising signal is transmitted at a predetermined interval. By repeating the transmission of the advertising signal at a predetermined interval in this manner, it is possible to provide an opportunity to periodically update the display of the operating state information on the display unit 41 of the smartphone 40 in accordance with a change in the operating state information.

[0084] In addition, in the cooking system 1 of this embodiment, two types of intervals for transmitting the advertising signal are prepared, 500 ms and 100 ms. If the operating state of the gas stove 10 does not change for a certain period (30 seconds), the interval for transmitting the advertising signal is set to 500 ms, and for a certain period after the operating state of the gas stove 10 changes, the interval for transmitting the advertising signal is set to 100 ms. If there is a change in the operating state of the gas stove 10, the advertising signal including the operating state information after the change is transmitted at short intervals, so that the change in the operating state can be quickly and accurately transmitted to the smartphone 40 and reflected in the display content on the display unit 41. On the other hand, if there is no change in the operating state of the gas stove 10 for a while, it is highly likely that the operating state has been transmitted to the smartphone 40 by the transmission of the advertising signal up to that point, so that the power consumption of the gas stove 10 can be reduced by lengthening the interval for transmitting the advertising signal and reducing the frequency.

[0085] Furthermore, in the cooking system 1 of this embodiment, when a special input that is not disclosed to general users is made on the gas stove 10 side, the operation information included in the advertising signal transmitted from the transmission unit 31 is switched from operation state information about the current operation state of the gas stove 10 to maintenance information about the operation history of the gas stove 10. For this reason, for example, a maintenance service worker for the gas stove 10 can make a special input and have the maintenance information displayed on the display unit 41 of the smartphone 40 for confirmation.

[0086] Although the cooking system 1 according to the embodiment has been described above, the present invention is not limited to the above embodiment, and can be embodied in various forms without departing from the gist of the present invention.

[0087] For example, in the above-mentioned embodiment, a gas stove 10 that burns a mixture of fuel gas and air has been described as an example of a cooking device that heats food to be cooked. However, the cooking device is not limited to the gas stove 10, and may be an electromagnetic induction heating stove (so-called IH stove) that includes a magnetic force generating coil and heats a metal cooking vessel by passing electricity through the coil.

[0088] In the above-described embodiment, the smartphone 40 has been described as an example of an information communication terminal compatible with wireless communication with a cooking appliance. However, the information communication terminal is not limited to the smartphone 40, and may be a tablet or the like as long as it has the same functions as the display unit 41, the receiving unit 42, the storage unit 43, and the display control unit 44 described above.

[0089] In the above-described embodiment, the smartphone 40 is set to a scan state in which the receiving unit 42 can receive the advertising signal on the condition that the application screen is displayed on the display unit 41 of the smartphone 40. However, a scan stop button and a scan start button may be provided on the application screen, and when the user taps the scan stop button, the scan state is temporarily cancelled, and when the user taps the scan start button, the scan state may be set again. In this way, the user can switch the scan state ON / OFF while the application screen is displayed on the display unit 41, and it is possible to reduce the power consumption of the smartphone 40 by turning it OFF when it is not necessary. In addition, when all three burners 13a, 13b, and 15a are stopped, the advertising signal transmitted from the transmitting unit 31 of the gas stove 10 may include an instruction to cancel the scan state, and the smartphone 40 that receives this advertising signal at the receiving unit 42 may temporarily cancel the scan state. Thereafter, when the user resumes combustion on any of the three burners 13a, 13b, and 15a, the user may tap the scan start button on the application screen of the smartphone 40 to resume the scan state.

[0090] In the above-mentioned embodiment, the operating state of each burner 13a, 13b, 15a (whether it is burning or stopped) and the contents of the error that has occurred are included in the advertising signal as the operating state information of the gas stove 10. However, the operating state information included in the advertising signal is not limited to these. For example, in the gas stove 10 having a timer function that allows the burning time (time until the fire is extinguished) of each burner 13a, 13b, 15a to be set on a timer, the advertising signal may include whether the timer is set or not and the remaining time of the timer as the operating state information. In addition, the flame power (for example, large, medium, small) during burning for each burner 13a, 13b, 15a may be included in the advertising signal as the operating state information.

[0091] Furthermore, in the above-mentioned embodiment, when a special input that is not disclosed to general users is detected, the operation information included in the advertisement signal (radio signal of the broadcast method) is switched from the operation state information to the maintenance information. However, the switching of the operation information included in the advertisement signal is not limited to this. For example, there are many types of information to be transmitted as the operation state information, and one operation state information may not be able to transmit all the information. In such a case, the operation state information may be divided into the first operation state information and the second operation state information, and a switching button (not shown) may be prepared on the gas stove 10, and based on the operation of the switching button, the operation state information may be switched from the first operation state information to the second operation state information and the advertisement signal may be transmitted.
