[0002] 2. Description of the Related Art Conventionally, a ventilation system has been known which is composed of a cooking appliance and a range hood and which exhausts oily smoke and the like generated by cooking to ventilate a room. In such a ventilation system, children or other people may mistakenly turn on the cooking appliance, which may result in a fire. In view of this, Patent Document 1 discloses providing a child lock on a cooking device to prevent children or the like from mistakenly putting the cooking device into a heating state. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-121287 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if there is a child lock, if the child lock is forgotten to be activated, children may accidentally turn on the cooking device. If an adult is near the cooking device, the adult will immediately notice that the device is on and can turn it off, but if no adult is present, the device will remain on, which may cause a fire.

[0005] The present invention has been made to solve the above-mentioned problems, and its object is to provide a ventilation system that enables a person away from a cooking appliance to notice that the cooking appliance has entered a heating state. [Means for solving the problem]

[0006] The ventilation system of the present invention is a ventilation system including at least a cooking appliance and a range hood, the ventilation system being capable of communicating with a mobile terminal, The ventilation system is characterized in that it includes a heating state determination unit that determines the heating state of the heating cooker, and a control unit, and when the heating state determination unit determines that the heating cooker has entered a heating state, the control unit sends a notification to the mobile terminal to start heating.

[0007] In the ventilation system of the present invention, the heating state determination unit may be a ventilation system configured to determine whether the heating cooker has entered a heating state based on detection information from a temperature detection unit provided in the heating cooker or operation information from the heating cooker. With this configuration, whether the cooking appliance is in a heated state is determined based on detection information from a temperature detection unit provided in the cooking appliance or operation information from the cooking appliance, so that it is possible to accurately and quickly determine whether the cooking appliance is in a heated state. Also, when cooking with a grill, it is possible to determine whether the cooking device is in a heated state.

[0008] In the ventilation system of the present invention, the heating state determination unit may be configured to determine that the cooking appliance is in a heating state when an instruction to start operating the blower provided in the range hood is received. With this configuration, when the blower of the range hood, which is mainly used when cooking with a cooking appliance, starts operating, it is possible to determine that the cooking appliance has entered a heating state and to notify the user.

[0009] In the ventilation system of the present invention, the range hood is equipped with a range hood operation unit, and when the instruction to start operating the blower comes from the range hood operation unit, the control unit is configured not to send a notification to the mobile terminal to start heating. With this configuration, unnecessary alerts from the mobile terminal can be prevented when the range hood operating unit is operated to intentionally operate the range hood blower, that is, when the cooking appliance is being used intentionally or when the range hood blower is being operated for the purpose of ventilating the room, and the cooking appliance is not being heated by mistake.

[0010] In the ventilation system of the present invention, the heating state determination unit may be a ventilation system that determines whether the cooking appliance has entered a heating state based on detection information from a temperature detection unit that detects the temperature above the cooking appliance and is provided in the range hood. With this configuration, temperature can be detected unobstructed from above the cooking appliance, and when the detected temperature indicates that the cooking appliance is in a heating state, it can be determined that the cooking appliance is in a heating state and notified.

[0011] In the ventilation system of the present invention, an information acquisition unit is provided that acquires information about the person who operated the heating cooker, and the control unit can be configured to send information about the person who operated the heating cooker to the mobile terminal when sending a notification to the mobile terminal that heating has started. With this configuration, the person who operated the cooking appliance can be known at the same time as the cooking appliance is turned on, so that the person who knows this can take appropriate measures thereafter.

[0012] In the ventilation system of the present invention, when an operation notification of a cooking appliance is received from the mobile terminal, the control unit can be configured to operate the cooking appliance in accordance with the received operation notification. With this configuration, the cooking appliance can be operated using a mobile terminal, so that even if a person who knows that the cooking appliance is in a heating state cannot rush to the cooking appliance immediately, appropriate action can be taken.

[0013] In the ventilation system of the present invention, if no operation instruction for the heating cooker is received within a certain time after sending a notification to start heating to the mobile terminal, the ventilation system can be configured to send a notification to start heating again to the mobile terminal. With this configuration, if the user does not notice the previous notification from the mobile terminal, it becomes easier for the user to notice that the cooking appliance has entered the heating state.

[0014] In the ventilation system of the present invention, if no operation notification of the cooking appliance is received within a certain period of time after a notification to start heating is sent again to the mobile terminal, the control unit can automatically stop heating of the cooking appliance. With this configuration, if the user is unable to receive a notification from the mobile device for some reason, the cooking appliance can automatically stop heating, thereby preventing a fire.

[0015] In the ventilation system of the present invention, the control unit can be configured to send a notification of heating start to the mobile terminal, and then, when the heating state determination unit determines that the heating cooker is in a heating stopped state, send a notification of heating end to the mobile terminal. With this configuration, a person who knows that the cooking appliance has entered a heating state can know that the cooking appliance has entered a heating stop state, and can therefore know that action has been taken.

[0016] In the ventilation system of the present invention, the control unit can be provided with a notification mode in which a notification is sent to the mobile terminal and a non-notification mode in which a notification is not sent to the mobile terminal, and the ventilation system can be configured so that either the notification mode or the non-notification mode can be selected. With this configuration, when the non-notification mode is selected, the mobile terminal does not notify that the cooking device is in a heating state, so that when the user does not wish to be notified that the cooking device is in a heating state, the notification is not made, which is not bothersome. For example, when cooking while carrying the portable terminal, the user can be prevented from being notified that a cooking appliance is in a heating state, which is not bothersome.

[0017] The ventilation system of the present invention may have the following configuration. (1) A ventilation system consisting of at least a cooking device and a range hood, The ventilation system is capable of communicating with a mobile terminal, and the ventilation system includes a heating state determination unit that determines a heating state of the cooking appliance, and a control unit; The ventilation system according to claim 1, wherein the control unit sends a notification of starting heating to the mobile terminal when the heating state determination unit determines that the cooking appliance is in a heating state.

Effect of the Invention

[0021] According to the ventilation system of the present invention, when a cooking device is placed in a heating state, a notification that heating has started is sent to a mobile terminal, so that even a person who is away from the cooking device can notice that the cooking device has been placed in a heating state via the mobile terminal, and a quick response can be made in cases where a child or the like mistakenly places the cooking device in a heating state. [Brief description of the drawings]

[0022] [Figure 1] 1 is a schematic explanatory diagram of the overall configuration of a ventilation system of the present invention. [Diagram 2] 3 is a flowchart of the operation of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] An embodiment of the ventilation system of the present invention will be described. The overall configuration of the ventilation system of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic explanatory diagram of the overall configuration of the ventilation system of the present invention. As shown in Fig. 1, the ventilation system 1 of the present invention comprises a cooking appliance 10 and a range hood 20. Note that the ventilation system may be provided with devices other than the cooking appliance 10 and the range hood 20. That is, the ventilation system 1 of the present invention comprises at least the cooking appliance 10 and the range hood 20, and includes a control unit (a cooking appliance control unit 12 and a range hood control unit 24). The ventilation system 1 is capable of communicating with a mobile terminal 30.

[0024] The cooking device 10 includes a heating section 11, a cooking device control section 12, a cooking device operation section 13, a cooking device communication section 14, and a temperature detection section 15 on the cooking side. The range hood 20 includes a blower 21, a lighting unit 22, a range hood operation unit 23, a range hood control unit 24, a range hood communication unit 25, and a temperature detection unit 26 on the range hood side. The mobile terminal 30 includes a display unit 31 which is a first notification unit, a speaker 32 which is a second notification unit, a mobile terminal control unit 33, a mobile terminal operation unit 34, and a mobile terminal communication unit 35. The mobile terminal 30 is a device that can be easily carried by a person, such as a mobile phone such as a smartphone, or a small personal computer such as a tablet.

[0025] The operation of the heat cooking section 10 will now be described. The cooking device operation unit 13 is operated by a human and sends heating start instructions, heating stop instructions, and heating intensity adjustment instructions to the cooking device control unit 12, and the cooking device control unit 12 starts heating, stops heating, and adjusts the heating intensity of the heating unit 11. Temperature detection unit 15 on the cooking device side detects the temperature of the top plate of heating unit 11 and the temperature of the bottom of the cooking device, and can detect the temperature of the food being cooked in cooking device 10, and sends the detected temperature to cooking device control unit 12. It may also be possible to detect the temperature inside the grill. The heating start, heating stop, and heating strength refer to ignition, extinguishing, and heat strength when the cooking appliance 10 is a gas stove, and refer to heat generation start, heat generation stop, and heat strength when the cooking appliance 10 is an IH stove.

[0026] The operation of the range hood 20 will now be described. The range hood operation unit 23 is operated by a person and sends instructions to start and stop the operation of the blower 21, to adjust the airflow volume, to turn on and off the lighting unit 22, etc. to the range hood control unit 24, and the range hood control unit 24 starts the operation of the blower 21, stops the operation of the blower 21, adjusts the airflow volume of the blower 21, turns on the lighting 22, and turns off the lighting 22. The temperature detector 26 on the range hood side detects the temperature above the cooking appliance 10, and the detected temperature (information) is sent to the range hood control unit 24.

[0027] The operation of the mobile terminal 30 will now be described. The display unit 31 displays characters, text, etc. The speaker 32 emits voice, sound, etc. The mobile terminal operation unit 34 sends various instructions to the mobile terminal control unit 33, and the mobile terminal control unit 33 controls the display unit 31 and the speaker 32 to perform a notification operation. The mobile terminal operation unit 34 may be an independent operation unit on the mobile terminal 30, or may be an operation unit that operates a screen like a smartphone.

[0028] The range hood communication unit 25 and the mobile terminal communication unit 35 are connected wirelessly to be able to communicate with each other, and the range hood 20 and the mobile terminal 30 are connected to be able to communicate directly. For example, the range hood communication unit 25 is connected wirelessly (WiFi) to a network 3 such as the Internet via a router 2, the mobile terminal communication unit 35 is connected to the network 3 wirelessly (wireless communication method according to a mobile data communication standard, or WiFi), and the mobile terminal 30 is connected wirelessly to the network 3 and the router 2 to be able to communicate directly with the range hood 20. The cooking appliance communication unit 14 and the range hood communication unit 25 are connected to each other wirelessly (Bluetooth (registered trademark)) or via a wired connection so that they can communicate with each other, and the cooking unit 10 and the mobile terminal 30 are indirectly connected to each other so that they can communicate with each other via the range hood 20.

[0029] Without being limited to this, the cooking appliance communication unit 14 and the mobile terminal communication unit 35 may be connected wirelessly (wireless communication method based on mobile data communication standards, or WiFi) as described above to communicate with each other, thereby directly connecting the cooking appliance 10 and the mobile terminal 30 to communicate with each other, and the cooking appliance communication unit 14 and the range hood communication unit 25 may be connected wirelessly or with a wire as described above to communicate with each other, thereby indirectly connecting the range hood 20 and the mobile terminal 30 to communicate with each other via the cooking appliance 10. Alternatively, the mobile terminal communication unit 35 may be wirelessly connected to the range hood communication unit 25 and the cooking appliance communication unit 14 so as to be able to communicate with each other, as described above, and the cooking appliance communication unit 14 and the range hood communication unit 25 may be communicatively connected to each other as described above. Also, the cooking appliance communication unit 14 or the range hood communication unit 25 may be directly wirelessly connected to the mobile terminal communication unit 35 so as to be able to communicate with each other (a wireless communication method based on a mobile data communication standard, or WiFi) without going through the router 2.

[0030] The ventilation system 1 has a heating state determination unit that determines the heating state of the cooking appliance 10. The heating state determination unit is composed of a control unit that performs determination and an information acquisition unit for determination, and determines whether the cooking appliance 10 has changed from a heating-stopped state to a heating state (hereinafter referred to as determining whether it has changed to a heating state), whether it is in a heating state, whether it is in a heating-stopped state, and whether it has changed from a heating state to a heating-stopped state. Then, either the heating cooker control unit 12 or the range hood control unit 24 sends a notification based on the judgment result of the heating state judgment unit from either the heating cooker communication unit 14 or the range hood communication unit 25 via the mobile terminal communication unit 35 to the mobile terminal control unit 33, and the mobile terminal control unit 33 is configured to control the display unit 31 and / or speaker 32 to make an alert based on the received notification.

[0031] For example, an application that issues an alert based on a notification from the cooking appliance control unit 12 or the range hood control unit 240 is set in the mobile terminal control unit 33, and the display unit 32 and / or speaker 32 are controlled to issue an alert based on the notification received by the mobile terminal control unit 33. The heating state is an ignition state if the cooking appliance 10 is a gas stove, and a heat generation state if the cooking appliance 10 is an IH stove. The heating stop state is an extinguished state if the cooking appliance 10 is a gas stove, and a state in which the flow of electricity to the IH coil is stopped if the cooking appliance 10 is an IH stove.

[0032] As a specific example, when the heating state determination unit determines that the heating cooker 10 has entered a heating state, either the heating cooker control unit 12 or the range hood control unit 24 sends a notification of the start of heating to the mobile terminal 30 as described above, and when the mobile terminal 30 receives the notification, the display unit 31 and / or speaker 32 of the mobile terminal 30 notifies that the heating cooker 10 has entered a heating state. This allows even a person who is away from the cooking appliance 10 to notice that the cooking appliance 10 has been turned on due to the notification from the mobile terminal 30, and allows for a quick response in cases where a child or the like mistakenly turns on the cooking appliance 10.

[0033] A first embodiment of this operation will be described with reference to the flow chart shown in FIG. The temperature of the cooking appliance 10 is detected by the temperature detection unit 15 on the cooking appliance side, and the detected temperature is sent to the cooking appliance control unit 12. If the temperature is a predetermined temperature (YES in step 101), it is determined that the appliance is in a heating state (step 102), and heating operator information is obtained (step 103). The cooking appliance control unit 12 outputs a notification of the start of heating, and the notification is sent from the cooking appliance communication unit 12 to the mobile terminal control unit 33 via the range hood communication unit 25 and the mobile terminal communication unit 35 (step 104). The mobile terminal control unit 33 controls the display unit 31 and / or the speaker 32 to notify that the cooking appliance 10 has entered a heating state.

[0034] The heating state determination unit continues to determine that the heating cooker control unit 12 is in a heating state unless the temperature detected by the temperature detection unit 15 on the heating cooker side falls below a predetermined temperature, and when the detected temperature drops from the predetermined temperature to below the predetermined temperature, the heating cooker control unit 12 determines that the heating cooker 10 has entered a heating stop state. In addition, the detected temperature of the temperature detection unit 15 on the cooking appliance side may be sent to the range hood control unit 24, and the range hood control unit 24 may determine whether the cooking appliance 10 has entered a heating state and send a notification of the start of heating to the mobile terminal control unit 33. To summarize the first embodiment, the temperature detection unit 15 and the cooker control unit 12 provided in the cooker 10, or the temperature detection unit 15 on the cooker side and the range hood control unit 24, constitute a heating state determination unit. The heating state determination unit determines that the cooker 10 is in the heating state when the temperature is a predetermined temperature, determines that the cooker is in the heating state while the temperature does not drop below the predetermined temperature, and determines that the cooker 10 is in the heating stopped state when the temperature drops from the predetermined temperature to below the predetermined temperature. That is, it determines whether the cooker 10 is in the heating state based on the temperature information of the cooker 10.

[0035] According to the first embodiment, whether the cooking appliance 10 has entered a heated state is determined based on the temperature detected by the temperature detection unit 15 provided in the cooking appliance 10, so that it is possible to accurately and quickly determine whether the cooking appliance 10 has entered a heated state. That is, since the temperature of the cooking device 10 is directly detected, there is no error between the actual cooking device temperature and the detected temperature, and the temperature can be determined quickly, so that the temperature can be determined accurately and quickly. In addition, by providing a temperature detector 15 for detecting temperature inside the grill of the cooking device 10, it is possible to detect the temperature of the grill, which is difficult to detect from above the cooking device 10. In other words, it is possible to determine whether the cooking device 10 is in a heated state even when cooking using the grill.

[0036] A second embodiment will now be described. When a heating start command is input to the heating cooker control unit 12 by operating the heating cooker operation unit 13, the heating cooker control unit 12 starts heating the heating unit 11 and determines that the heating cooker 10 is in a heating state. When a heating stop instruction is input to the heating cooker control unit 12 by operating the heating cooker operation unit 13, the heating cooker control unit 12 stops heating of the heating unit 11 and determines that the heating cooker 10 has entered a heating stop state. The other configuration is similar to that of the first embodiment.

[0037] To summarize the second embodiment, a heating state determination unit is constituted by the heating cooker operation unit 13 and the heating cooker control unit 12, which determines that a heating state has been entered when a heating start instruction is input, determines that the heating state is in progress while the instruction is being input, and determines that the heating stop state is in progress when a heating stop instruction is input. That is, it is determined based on the operation information of the cooking appliance 10 whether the cooking appliance 10 is in a heating state. According to this configuration, it is possible to accurately and quickly determine that the cooking device 10 has entered the heating state. That is, since the determination is made based on the operation of the cooking device operation unit 12, there is no error and the determination is made quickly, so that the determination can be made accurately and quickly. Also, even when cooking with a grill, it is possible to determine whether the cooking device 10 is in a heating state.

[0038] A third embodiment will now be described. When a command to start operation of the blower 21 is input from the range hood operation unit 23 to the range hood control unit 24, the range hood control unit 24 starts operation of the blower 21 and determines that the cooking appliance 10 has entered a heating state. The range hood control unit 24 sends a notification of the start of heating from the range hood communication unit 25 via the mobile terminal communication unit 35 to the mobile terminal control unit 33, and the mobile terminal control unit 33 controls the display unit 31 and / or speaker 32 to notify that the heating cooker 10 has entered a heating state. When an instruction to stop operation of the blower 21 is input from the range hood operation unit 23 to the range hood control unit 24, it is determined that the cooking appliance 10 has entered a heating stop state.

[0039] The instruction to start operation of the blower 21 is not limited to being given from the range hood operation unit 23 . For example, if an instruction to start the operation of the blower 21 is input to the range hood control unit 24 in conjunction with the start of the heating state of the cooking appliance 10, so that the blower 21 starts operating, it may be possible to determine that the cooking appliance 10 has entered the heating state based on the instruction to start operation. In addition, if a heating start instruction from the heating cooker operation unit 13 is sent from the heating cooker communication unit 14 via the range hood communication unit 25 to the range hood control unit 24, and input into the range hood control unit 24 as an instruction to start operation of the blower 21 to start operation of the blower 21, it may be possible to determine that the heating cooker 10 has entered a heating state based on the operation start instruction. In addition, when a heating start instruction from the heating cooker operation unit 13 is input to the heating cooker control unit 12, it may be determined that a heating cooker 10 has entered a heating state by assuming that a heating cooker operation unit 13 has input an instruction to start operation of the blower 21.

[0040] To summarize the third embodiment, the range hood operation unit 23 and the range hood control unit 24 constitute a heating state determination unit, or the cooking appliance operation unit 13 and the cooking appliance control unit 12 constitute a heating state determination unit, which determines that the cooking appliance 10 has entered a heating state when an instruction to start the operation of the blower 21 is input, and determines that the cooking appliance 10 has entered a heating stop state when an instruction to stop the operation of the blower 21 is input. In other words, it determines that the cooking appliance 10 has entered a heating state when an instruction to start the operation of the blower 21 is input. Since the operation of the blower 21 of the range hood 20 is performed when cooking is performed using the cooking appliance 10, there is no problem if the mobile terminal 30 notifies the user that the cooking appliance 10 is in a heating state in response to an instruction to start the operation of the blower 21 of the range hood 20. This makes it possible to detect without fail the state in which the cooking device 10 is in the heated state. More preferably, by receiving an instruction to start cooking with the cooking device 10 and instructing the blower 21 to start operation, it is possible to eliminate notification when the cooking device 10 is not in the heated state.

[0041] A fourth embodiment will now be described. The heating state determination unit determines that the device is in a heated state as in the third embodiment, and notifies the mobile terminal 30 of the start of heating when an instruction to start operation of the blower 21 is input to the range hood control unit 24 in conjunction with the start of the heating state of the heating cooker 10 in the third embodiment, when a heating start instruction from the heating cooker operation unit 13 is input to the range hood control unit 24 as an instruction to start operation of the blower 21, and when an instruction to start operation of the blower 21 is input when the heating start instruction from the heating cooker operation unit 13 is input to the heating cooker control unit 12, that is, when an instruction to start operation of the blower 21 is input from other than the range hood operation unit 23. In this embodiment, when an instruction to start operation of the blower 21 is input from the range hood operation unit 23 to the range hood control unit 24, the range hood control unit 24 does not notify the mobile terminal 30 of the start of heating. Therefore, the mobile terminal 30 does not notify that the cooking appliance 10 has entered a heating state. With this configuration, it is possible to prevent the mobile terminal 30 from making an unnecessary notification that the cooking appliance 10 is in a heating state.

[0042] In other words, operating the range hood operating unit 23 to start operating the blower 21 is considered to be an intentional operation, for example, a state in which the cooking appliance 10 is being used intentionally for cooking, etc., or a state in which the blower 21 of the range hood 20 is being operated for another reason, for example, to ventilate the room, and therefore, at that time, it is meaningless and unnecessary for the mobile terminal 30 to notify that the cooking appliance 10 has entered a heating state.

[0043] A fifth embodiment will now be described. The range hood control unit 24 is configured to determine whether the cooking appliance 10 is in a heating state based on the temperature above the cooking appliance 10 detected by the temperature detection unit 26 on the range hood side. For example, if the detected temperature is a predetermined temperature, it is determined that the cooking appliance 10 is in a heating state, if the detected temperature does not drop below the predetermined temperature, it is determined that the cooking appliance 10 is in a heating state, and if the detected temperature drops below the predetermined temperature, it is determined that the heating has stopped. If it is determined that the heating state has been reached, the range hood control unit 24 sends a notification of the start of heating from the range hood communication unit 25 via the mobile terminal communication unit 35 to the mobile terminal control unit 32, and under the control of the mobile terminal control unit 33, the display unit 31 and / or speaker 32 notify that the cooking appliance 10 has entered the heating state.

[0044] In summary, the temperature detection unit 26 on the range hood side and the range hood control unit 24 constitute a heating state determination unit, which determines whether the heating state has been reached based on the temperature above the cooking appliance 10, and if it is determined that the heating state has been reached, the range hood control unit 24 notifies the start of heating and the mobile terminal 30 notifies the user that the heating state has been reached. That is, the heating state determination unit is configured to determine whether the cooking appliance 10 is in a heating state based on the detection information from the temperature detection unit 26 on the range hood side.

[0045] A sixth embodiment will now be described. As shown in FIG. 1, a camera 27 is provided on the range hood 20 so that a person who operates the cooker 10 by operating the cooker operating section 13 of the cooker 10 can be photographed. The image captured by the camera 27 is transmitted to the judgment unit 28, which compares it with a database or the like to determine, through an authentication system, whether the person who performed the heating operation is a person who has been registered in advance or an unregistered person (e.g., a child). The decision of the decision unit 28 is sent to the range hood control unit 24 , and then to the mobile terminal control unit 33 via the range hood communication unit 25 and the mobile terminal communication unit 35 .

[0046] When the mobile terminal control unit 33 receives the notification of the start of heating, it controls the display unit 31 and / or the speaker 32 to notify the user that the cooking appliance 10 has entered a heating state and whether the person who performed the heating operation of the cooking appliance 10 is a registered person or a person to be registered. If the person is a registered person, it may also notify the user of who performed the heating operation. In summary, the camera 27 and the judgment unit 28 constitute an information acquisition unit that acquires information about the person who performed the heating operation of the heating cooker 10, and the mobile terminal 30 notifies the user that the heating cooker 10 has entered a heating state along with information about the person who performed the heating operation on the heating cooker 10. With this configuration, the person who operated the cooking appliance 10 for heating can be known at the same time that the cooking appliance 10 is in a heating state, so that the person who knows this can take appropriate measures thereafter.

[0047] For example, if the person who cooked using the cooking appliance 10 is a registered person, there is no problem and the cooking appliance 10 is left as is, but if the person is not registered (a child), the cooking appliance 10 is stopped from heating by some means. Also, the image captured by the camera 27 can be displayed as it is as an image on the mobile terminal 30 as information about the person who performed the heating operation of the cooking appliance 10. In this case, the camera 27 constitutes an information acquisition unit that acquires information about the person who performed the heating operation. The camera 27 may be installed not only on the range hood 20 but also on a wall surrounding the range hood 20 . The means for determining the person who performed the heating operation of the cooking device 10 is not limited to a camera. For example, the GPS location information of the registered mobile terminal 30 at the time the heating operation was performed may be acquired to determine that the person who performed the heating operation was a person who was near the cooking device 10, or if there is no registered mobile terminal 30 nearby, it may be determined that the heating operation was performed by a child or the like. It may also be determined whether the mobile terminal 30 belongs to a registered person or an unregistered person (child). In this case, the mobile terminal 30 constitutes an information acquisition unit that acquires information about the person who performed the heating operation.

[0048] A seventh embodiment will now be described. A cooking appliance operation application is installed on the mobile terminal 30 , and the like, so that the mobile terminal operation unit 33 can input operation instructions for the cooking appliance 10 to the mobile terminal control unit 32 . Operation instructions for the cooking appliance 10 input to the mobile terminal control unit 32 are sent from the mobile terminal communication unit 35 via the range hood communication unit 25 and the cooking appliance communication unit 14 to the cooking appliance control unit 12, and the cooking appliance control unit 12 operates the cooking appliance 10. In summary, the mobile terminal operation unit 34 is configured to be able to input operation instructions for the cooking appliance 10 to the mobile terminal 30, and to be able to operate the cooking appliance 10 via the mobile terminal 30.

[0049] With this configuration, the cooking device 10 can be operated using the mobile terminal 30, so that a person who receives a notification that the cooking device 10 is in a heating state can take appropriate action even if he or she cannot immediately rush to the cooking device 10. The operation contents of the cooking device 10 include stopping heating (extinguishing), maintaining, child lock, and the like.

[0050] An eighth embodiment will now be described. Even if the seventh embodiment is configured to allow operation instructions for the cooking device 10 to be given by the mobile terminal 30, if the user forgets to operate the cooking device 10 or does not notice that the cooking device 10 has entered a heating state, the cooking device 10 will remain in a heating state. The eighth embodiment is configured to solve this problem. A control unit that notifies a mobile terminal 30 such as a cooking device control unit 12 and a range hood control unit 24 is configured to have a function of counting the time since a heating start notification was sent, a function of detecting whether or not a cooking device 10 operation notification has been received, and a function of sending the heating start notification again when a cooking device 10 operation notification has not been received even after a certain time has passed since the notification was sent.

[0051] For example, the range hood control unit 24 is configured to have a counting function that counts the time after sending a notification to start heating to the mobile terminal 30, a function that determines whether an operation instruction for the heating cooker 10 has been received from the mobile terminal 30, and a function that sends the notification to start heating again if no operation instruction is received after counting a certain amount of time. As a result, if the range hood control unit 24 does not receive an operation instruction for the cooking appliance 10 from the mobile terminal 30 even after a certain time has elapsed since sending the notification of the start of heating, the range hood control unit 24 can send the notification of the start of heating again to the mobile terminal 30. With this configuration, if the user does not realize that cooking appliance 10 has entered a heating state due to a previous notification, it is easier for the user to realize that cooking appliance 10 has entered a heating state.

[0052] This operation is explained using the flowchart in Figure 2. If there is no instruction to operate the heating and cooking device 10 after notifying the mobile terminal 30 (step 104) (NO in step 105), counting continues, and if a certain period of time has elapsed (YES in step 106), a notification is sent again to the mobile terminal 30 (step 107). If there is an instruction to operate the cooking appliance 10 (YES in step 105), the cooking appliance 10 is operated (step 108).

[0053] A ninth embodiment will now be described. As in the eighth embodiment, if the notification of the start of heating is sent again to the mobile terminal 30 but is not noticed, the cooking device 10 remains in the heating state. The ninth embodiment is configured to solve this problem. The range hood control unit 24 resets the count of the count function by sending the notification of the start of heating again, so that the count function starts counting again. If no operation instruction for the cooking appliance 10 is received before the time counted again reaches a certain time, the range hood operation unit 23 sends an instruction to stop heating the cooking appliance 10 from the range hood communication unit 25 via the cooking appliance communication unit 14 to the cooking appliance control unit 12, and the cooking appliance control unit 12 controls the heat generating unit 11 to stop heating, thereby putting the cooking appliance 10 into a heating-stopped state.

[0054] When the cooking device control unit 12 sends the notification of the start of heating, the above operations can be performed by the cooking device control unit 12 alone. In summary, if the range hood control unit 24 or the cooking appliance control unit 12 does not receive any operation instructions for the cooking appliance 10 from the mobile terminal 30 within a certain period of time after sending another notification to start heating, the cooking appliance control unit 12 automatically stops heating the cooking appliance 10. With this configuration, if for some reason the user is unable to receive notification that the cooking device 1 has entered a heating state, the cooking device 10 is automatically stopped from heating, thereby preventing a fire from breaking out. The fixed time in the eighth embodiment and the fixed time in the ninth embodiment may be the same time or may be different times.

[0055] This operation is explained using the flowchart in Figure 2. If no instruction to operate the cooking device 10 is received after sending a notification again to the mobile terminal 30 (step 107) (NO in step 109), the counting continues, and if a certain time has elapsed (YES in step 110), the range hood control unit 24 instructs the cooking device 10 to stop heating (step 111). If there is a notification of operation of the cooking appliance 10 (YES in step 109), the operation of the cooking appliance 10 is executed (step 108).

[0056] A tenth embodiment will now be described. This embodiment is configured such that the mobile terminal 30 can notify the user that the cooking appliance 10 has automatically been put into a heating stop state, as in the ninth embodiment. When the heating cooker 10 is in a heating state (after the heating state determination unit has determined that it is in a heating state), if the detected temperature of the temperature detection unit 15 on the heating cooker side drops below a predetermined temperature, the heating cooker control unit 12 determines that the heating cooker 10 has entered a heating stop state, and sends a notification of the end of heating to the mobile terminal control unit 33 via the heating cooker communication unit 14, the range hood communication unit 25, and the mobile terminal communication unit 35. The mobile terminal control unit 33 is configured to control the display unit 31 and / or the speaker 32 to notify the user that the cooking appliance 10 has automatically stopped heating.

[0057] The range hood control unit 24 can determine that the heating cooker 10 has entered the heating stopped state when, for example, an instruction to stop operation of the blower 21 is received, or when the detected temperature of the temperature detection unit 26 on the range hood side drops below a predetermined temperature. In summary, after the control unit sends a notification of the start of heating to the mobile terminal 30, if the heating state determination unit determines that the heating cooker 10 has entered a heating stop state, the control unit sends a notification of the end of heating to the mobile terminal 30, and the mobile terminal 30 notifies the mobile terminal 30 that the heating cooker 10 has automatically entered a heating stop state. With this configuration, a person who receives a notification that the cooking appliance 10 is in a heating state can know that a measure has been taken by knowing that the cooking appliance 10 has automatically stopped heating. Also, even if the heating state is stopped after a notification to start heating is sent, for example, if the heating state is stopped by someone else, a notification that the heating state has been stopped may be sent to the mobile terminal 30, and the mobile terminal 30 may notify the user.

[0058] This operation is explained using the flowchart in Figure 2. After the heating cooker 10 issues a notification to stop heating (step 111), if the heating state determination unit determines that the heating cooker 10 has entered a heating stopped state (YES in step 112), it sends a notification of the end of heating to the mobile terminal 30, and the mobile terminal 30 notifies the user that the heating cooker 10 has automatically entered a heating stopped state (step 113).

[0059] An eleventh embodiment will now be described. The control unit (heating cooker control unit 12 or range hood control unit 24) is configured to set a notification mode in which notifications such as notification of heating start or heating stop are sent, and a non-notification mode in which notifications such as notification of heating start or heating stop are not sent, and the user can select either the notification mode or the non-notification mode. In summary, the control unit is configured to have a notification mode in which notifications such as a notification that heating has started or stopped are sent to the mobile terminal 30, and a non-notification mode in which notifications such as a notification that heating has started or stopped are not sent to the mobile terminal 30, allowing the user to select either the notification mode or the non-notification mode.

[0060] With this configuration, by selecting the non-notification mode, the mobile terminal 30 does not notify the user that the cooking device 10 is in a heating state or a heating stopped state, so that such notifications can be suppressed when such notifications are not desired, and are not bothersome. For example, when cooking while carrying the mobile terminal 30, it is possible to prevent the user from being notified that the cooking appliance 10 is in a heating state, which is not bothersome. In the above embodiment, the heating state determination unit is configured by the heating cooker control unit 12 and the range hood control unit 24, but a control unit may be provided separately from the heating cooker control unit 15 and the range hood control unit 24, and the control in this embodiment may be performed by the control unit. In addition, the combination of the control unit and the determination information constituting the heating state determination unit is not limited to the embodiment, and various combinations are possible. In addition, a plurality of embodiments can be arbitrarily combined to form one embodiment. For example, by combining the second embodiment and the eleventh embodiment, an exhaust system can be configured in which a notification mode and a non-notification mode can be selected, the heating state is determined by the operation of the heating cooker operation unit 13, and a notification is sent to the mobile terminal 30.
