Description

[Technical field]

[0001] The present invention relates to a ventilation system that exhausts oily smoke and the like generated during cooking using a cooking appliance to ventilate a room. Regarding. [Background technology]

[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. Such ventilation systems cook food by heating the cooking appliance, and various things can happen during cooking. For example, the heating state of the cooking appliance may become abnormal during cooking, and if the cook is not aware of this, the cooking may fail. Therefore, Patent Document 1 describes a technique for detecting and reporting abnormal combustion in a gas cooker. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5089746 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even though combustion is normal during cooking, several things happen that a cook would want to be aware of. For example, a person may perform a task other than cooking while cooking. For example, a person may prepare a different dish while cooking a stew. In addition, when cooking stews or other dishes that require long periods of heating while the cooking vessel is left on the heating section of the cooker, people may want to use the time effectively by doing something other than cooking or by taking a break in a place away from the cooker (such as the living room). However, in such cases, the person may forget that they are cooking and not realize that the cooking time has elapsed, causing the food to overcook or burn.

[0005] The present invention has been made to solve the above-mentioned problems, and its object is to provide a ventilation system that can notify a cooker who is away from a cooking appliance that cooking is in progress. [Means for solving the problem]

[0006] The ventilation system of the present invention is a ventilation system consisting of at least a cooking appliance and a range hood, the ventilation system being capable of communicating with a mobile terminal, the ventilation system comprising a heating state determination unit that determines the heating state of the cooking appliance, and a control unit, the control unit sending a notification to the mobile terminal when a condition is satisfied when the heating state determination unit determines that the cooking appliance is in a heating state.

[0007] In the ventilation system of the present invention, the ventilation system can be equipped with a kitchen timer function, and the control unit can be configured to send a timer notification to the mobile terminal when a time set by the kitchen timer function has elapsed. With this ventilation system, the cook can be notified via a mobile device when the time set by the kitchen timer has elapsed.

[0008] In the ventilation system of the present invention, the ventilation system is equipped with a temperature detection unit that detects the temperature of the food being cooked in the heating cooker, and the control unit can be configured to send an advance notification to the mobile terminal when the temperature detected by the temperature detection unit reaches a predetermined temperature. With this ventilation system, the cooker can be notified via a mobile device when the food being cooked in the cooking appliance has reached a specified temperature.

[0009] In the ventilation system of the present invention, the ventilation system is equipped with a temperature detection unit that detects the temperature of the food being cooked in the heating cooker, the heating cooker is capable of setting the heating temperature of the food, and the control unit can be configured to send an advance notification to the mobile terminal when the detected temperature of the temperature detection unit is a specified temperature lower than the set heating temperature of the food. With this ventilation system, the cook can be notified via a mobile device when the temperature of the food being cooked is a specified number of degrees lower than the set temperature. This allows the cook ample time to perform other tasks until the mobile device receives the advance notification, and then allows the cook to immediately begin cooking (the next step) once the food temperature has been reached.

[0010] In the ventilation system of the present invention, the ventilation system has an automatic cooking mode, and the control unit can be configured to send an advance notification to the mobile terminal when the heating time of the food being cooked in the automatic cooking mode is shorter than the specified time by a predetermined amount. With this ventilation system, when the heating time for the food is set as a specified time in automatic cooking mode, the cook can use a mobile device to be notified that the heating time for the food is a specified amount of time shorter than the specified time. This allows the cook to carry out other tasks at their leisure until the mobile device receives the advance notification, and once the specified time has passed after the mobile device receives the advance notification, the cook can immediately begin cooking (the next step).

[0011] In the ventilation system of the present invention, the control unit can be equipped with a counter, and the counter starts counting when the heating state determination unit determines that the heating cooker has entered a heating state, and the control unit can be configured to send a count notification to the mobile terminal when the counter's count time reaches a predetermined time. With this ventilation system, the cook can be notified via a mobile device when a predetermined time has elapsed since the start of cooking, preventing food from being overcooked or burnt.

[0012] In the ventilation system of the present invention, the count of the counter can be reset when a notification is sent to the mobile terminal. With this ventilation system, the counter is reset when a notification is sent to the mobile device, so notifications can be sent to the mobile device continuously.

[0013] In the ventilation system of the present invention, when a notification set by the cook other than a count notification is sent to the mobile terminal, the control unit can be configured to not send a count notification but to send the notification set by the cook other than the count notification if the timing to send the count notification comes before the timing to send the notification set by the cook other than the count notification. With this ventilation system, if a count notification is sent before a notification set by a cook other than the count notification, there is a possibility that the count notification will be mistaken for a notification set by a cook other than the count notification. However, by not sending a count notification, there is no risk of the cook mistaking the count notification for a notification set by a cook other than the count notification. For example, since the timer notification is not sent to the mobile device until the time set by the cook in the kitchen timer function has elapsed, it is possible to prevent unnecessary notifications from being sent before the time intended by the cook has elapsed. In other words, the time intended by the cook is the set time of the kitchen timer.

[0014] In the ventilation system of the present invention, the predetermined time can be set arbitrarily. With this ventilation system, the time interval between the start of cooking and sending the counter notification can be set to any time, and the count notification can be sent to the mobile device at an appropriate time interval depending on the type of cooking. In addition, by setting the time according to the cook's usual cooking habits and behavioral patterns, count notifications can be sent to the cook's mobile device at the optimal timing.

[0015] In the ventilation system of the present invention, the ventilation system is equipped with a human presence sensor that detects the presence or absence of a person near the range hood, and a counter that counts the time during which the human presence sensor does not detect a person, and the control unit can be configured to send a count notification to the mobile terminal when the counter has counted a predetermined time while the heating state determination unit has determined that the heating cooker is in a heating state. With this ventilation system, the mobile terminal issues a count notification when no one has been near the range hood for a specified time, so that a cook who is not near the range hood can use the mobile terminal to be notified that they have been away for a specified time during cooking.

[0016] In the ventilation system of the present invention, the ventilation system may be equipped with a distance detection means for detecting the distance between a mobile terminal and a cooking appliance or the distance between a mobile terminal and the range hood, and the control unit may be configured to send an exit notification to the mobile terminal when the heating state determination unit determines that the cooking appliance is in a heating state and the distance detected by the distance detection means exceeds a certain distance. With this ventilation system, when a cooker moves away from a cooking appliance or a range hood by more than a certain distance while holding a mobile terminal, an exit notification is sent to the mobile terminal, so that the cooker can be made aware that he or she has moved away from the cooking appliance or range hood by more than a certain distance while cooking by using the mobile terminal.

[0017] In the ventilation system of the present invention, the ventilation system is equipped with a human presence sensor that detects the presence or absence of a person near a range hood, and the control unit is configured to not send a notification to the mobile terminal when the human presence sensor detects a person when sending a notification. The ventilation system can prevent notifications from being sent to mobile devices when a cook is near the range hood.

[0018] In the ventilation system of the present invention, the range hood and / or the cooking appliance can be controlled based on operation instructions sent from the mobile terminal, and the control unit can be configured to send a notification that heating is continuing and an operation notification requesting operation instructions for the range hood and / or the cooking appliance to the mobile terminal. With this ventilation system, the range hood and / or cooking appliance can be operated using a mobile terminal, allowing appropriate action to be taken even if the cook cannot immediately rush to the cooking area.

[0019] In the ventilation system of the present invention, if no operation instruction is received for the range hood and / or cooking appliance within a certain time period after sending the operation notification, the ventilation system can be configured to send a notification that heating is continuing to the mobile terminal again. With this ventilation system, if a cook does not notice that a previous notification was sent to the mobile device, it is possible to make it easier for the cook to notice that a notification has been sent to the mobile device.

[0020] In the ventilation system of the present invention, if no operation instructions are received from the range hood and / or cooking appliance within a certain period of time after a notification that heating is continuing is sent again to the mobile terminal, the control unit can automatically stop heating the cooking appliance. With this ventilation system, if for some reason the cook is unable to know that a notification has been sent to their mobile device, the cooking appliance will automatically stop heating, protecting the food being cooked and preventing a fire.

[0021] In the ventilation system of the present invention, the ventilation system can be equipped with a temperature information detection means for detecting temperature information of the food being cooked in the heating cooker, and the control unit can be configured to send a temperature notification to the mobile terminal when sending a notification to the mobile terminal, the temperature notification displaying the temperature information of the food being cooked detected by the temperature information detection means. With this ventilation system, the cook can know the cooking status from the temperature information of the food, making it easier for them to make appropriate cooking decisions.

[0022] 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. This ventilation system sends notifications only when the cook selects the notification mode, so notifications are not sent when the cook does not want them to. Therefore, the cook does not receive notifications on his / her mobile device when he / she does not want them to, so it is not bothersome for the cook. For example, when cooking while carrying a mobile terminal, it is possible to prevent notifications from being received, so that it is not bothersome.

[0023] In the ventilation system of the present invention, the ventilation system can be configured to be capable of sending a plurality of different notifications, and the control unit can be configured to send only a notification selected from the plurality of notifications in the notification mode. With this ventilation system, only notifications selected by the cook in the notification mode are sent, and unnecessary notifications that were not selected are not sent. Therefore, unnecessary notifications are not received by the mobile device, which is not bothersome for the cook. For example, by not selecting notifications that are unnecessary for the cook, the cook can avoid being notified that the unselected notifications have been received by the mobile device, which is not bothersome.

[0024] In the ventilation system of the present invention, the heating state determination unit may determine the heating state of the cooking appliance based on detection information from a temperature detection unit provided in the cooking appliance or operation information of the cooking appliance. With this ventilation system, 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 detect that the cooking device is in a heating state.

[Figure 4] 4 is a flowchart showing the operation of a portion of the ventilation system of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] 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, which will be described later). The ventilation system 1 is capable of communicating with a mobile terminal 30.

[0038] 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.

[0039] 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.

[0040] 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 detection unit 26 on the range hood side detects the temperature above the cooking appliance 10 and can detect the temperature of the food being cooked in the cooking appliance 10. The detected information (temperature) is sent to the range hood control unit 24.

[0041] The operation of the mobile terminal 30 will now be described. The display unit 31 displays characters, text, images, etc. The speaker 32 emits voice, sounds, 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.

[0042] A communication-enabling connection between the ventilation system 1 and the mobile terminal 30 will be described. 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.

[0043] Without being limited thereto, the cooker communication unit 14 and the mobile terminal communication unit 35 may be connected wirelessly (wireless communication method according to a mobile data communication standard, or WiFi) as described above to enable mutual communication between the cooker 10 and the mobile terminal 30 to be directly connected to each other to enable communication, and the cooker communication unit 14 and the range hood communication unit 25 may be connected wirelessly or with a wire to enable mutual communication between the range hood 20 and the mobile terminal 30 to be indirectly connected to each other to enable communication via the cooker 10. Also, the cooker communication unit 14 or the range hood communication unit 25 may be directly connected to the mobile terminal communication unit 35 wirelessly (wireless communication method according to a mobile data communication standard, or WiFi) to enable communication without going through the router 2. 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, respectively, 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 wirelessly connected to be able to communicate with each other as described above.

[0044] The ventilation system 1 has a heating state determination unit that determines the heating state of the cooking appliance 10. The heating state is an ignition state when the cooking appliance 10 is a gas stove, and a state in which the IH coil is energized when the cooking appliance 10 is an IH stove. A first configuration of the heating state determination unit will be described. The temperature of the cooker 10 is detected by a temperature detection unit 15 on the cooker side, and the detected temperature is sent to the cooker control unit 12, which determines the heating state of the cooker 10 based on the detected temperature. For example, if the detected temperature reaches a predetermined temperature, it is determined that the device is in a heated state, if the detected temperature does not fall below the predetermined temperature, it is determined that the device is in a heated state, and if the detected temperature falls from the predetermined temperature to below the predetermined temperature, it is determined that the device is in a heating-stop state. In other words, if the detected temperature is equal to or higher than the predetermined temperature, it is determined that the device is in a heated state.

[0045] The temperature detected by temperature detection unit 15 on the cooking appliance side may be sent to range hood control unit 24, and range hood control unit 24 may determine the heating state of cooking appliance 10. In other words, the temperature detection unit 15 and the cooking device control unit 12 provided in the cooking device 10 constitute a heating state determination unit, or the temperature detection unit 15 on the cooking device side and the range hood control unit 24 constitute a heating state determination unit. The heating state determination unit determines that the cooking appliance 10 is in a heating state if the detected temperature is equal to or higher than a predetermined temperature. That is, the heating state of the cooking appliance 10 is determined based on the temperature information of the cooking appliance 10.

[0046] In this way, since the heating state of the cooking device 10 is determined based on the temperature detected by the temperature detection unit 15 included in the cooking device 10, the heating state of the cooking device 10 can be determined accurately and quickly. 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, the heating state of the cooking device 10 can be determined even when cooking using the grill.

[0047] A second configuration of the heating state determination unit will be described. When a heating start instruction is input to the heating cooker control unit 12 by operation of the heating cooker operation unit 13, the heating cooker control unit 12 determines that the heating cooker 10 is in a heating state, and determines that the heating cooker 10 is in a heating state until a heating stop instruction is input to the heating cooker control unit 12 by operation of the heating cooker operation unit 13, and when the heating stop instruction is input, the heating cooker control unit 12 determines that the heating cooker 10 is in a heating stop state. That is, the cooking device operation unit 13 and the cooking device control unit 12 constitute a heating state determination unit, which continues to determine that the heating state is in progress from when a heating start instruction is input until when a heating stop instruction is input. That is, the heating state of the cooking appliance 10 is determined based on the operation information of the cooking appliance 10.

[0048] Since the determination is made based on the operation information of the cooking device 10 in this manner, the heating state of the cooking device 10 can be determined accurately and quickly. That is, since the determination is made based on the operation of cooking device operation unit 13, there is no error and the determination is made quickly, so that the determination can be made accurately and quickly. Also, the heating state of the cooking device 10 can be determined even when cooking with a grill. The heating state determination unit is not limited to the first and second configurations, but may have the following configuration.

[0049] A third configuration in which the detected temperature of the temperature detection unit 26 on the range hood side is input to the range hood control unit 24, and the range hood control unit 24 determines the heating state of the cooking appliance 10 based on the input detected temperature in the same manner as the heating state determination unit of the first configuration. A fourth configuration in which, 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, it is determined that the cooking appliance 10 has entered a heating state, the cooking appliance 10 is determined to be in a heating state until an instruction to stop operation is input from the range hood operation unit 23, and when an instruction to stop operation is input, it is determined that the cooking appliance 10 is in a heating-stop state.

[0050] The ventilation system 1 includes a control unit that sends a notification to the mobile terminal 30 when a condition is satisfied while the heating state determination unit determines that the cooking appliance 10 is in a heating state. In the following description, this control unit is referred to as the cooking appliance control unit 12 or the range hood control unit 24, but a control unit may be provided separately from the cooking appliance control unit 12 and the range hood control unit 24. With this configuration, when the heating state determination unit determines that the cooking appliance 10 is in a heating state and the condition is satisfied, that is, when the condition is satisfied during cooking, the control unit sends a notification to the mobile terminal 30. When the mobile terminal 30 receives the notification, it issues a report according to the received notification.

[0051] For example, when the cooking device control unit 12 determines the heating state of the cooking device 10, an application that issues a notification in response to a notification from the cooking device control unit 12 is installed in the mobile terminal control unit 33. Then, the cooking appliance control unit 12 outputs a notification, which is sent from the cooking appliance communication unit 14 via the range hood communication unit 25 and 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 make an announcement according to the received notification, and makes an announcement according to the received notification. Therefore, when the conditions are met during cooking, the mobile terminal 30 notifies the user, so that the user can be informed that cooking is in progress. In addition, since the notification is made via the mobile terminal 30, even a cooker who is away from the cooking appliance 10 can notice the notification, and can also inform a cooker who is away from the cooking appliance 10 that cooking is in progress.

[0052] A first embodiment of the ventilation system of the present invention will be described. As shown in FIG. 1, a kitchen timer 27 is provided in the range hood 20, so that the range hood 20 has a kitchen timer function. The kitchen timer 27 may be provided in the cooking appliance 10 so that the cooking appliance 10 has a kitchen timer function. In other words, the ventilation system 1 may have a kitchen timer function. In addition, the kitchen timer 27 may be configured to be operated by the mobile terminal 30. The heating state determination unit is of a first configuration, and the heating cooker control unit 12 is configured to output a timer notification when time-up information of the kitchen timer 27 is received while it is determined that the heating cooker 10 is in a heating state.

[0053] The configuration will be explained together with the operation. A set time (cooking time, heating time, etc.) is set in kitchen timer 27 and cooking begins. When cooking is started, the temperature detected by temperature detector 15 on the cooking appliance side reaches a predetermined temperature, and cooking appliance controller 12 determines that cooking appliance 10 is in a heating state, as explained above. Then, when kitchen timer 27 times out (the set time has elapsed), it sends time-up information to range hood control unit 24. Range hood control unit 24 sends the time-up information to cooking appliance control unit 12 via range hood communication unit 25 and cooking appliance communication unit 14. When the heating cooker control unit 12 determines that the heating cooker 10 is in a heating state, it receives time-up information and outputs a timer notification. The timer notification is sent 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.

[0054] The mobile terminal control unit 33 controls the display unit 31 and / or the speaker 32 to give a timer notification. The timer notification is a notification in response to a timer notification that the time on the kitchen timer 27 is up. In other words, the condition is satisfied when kitchen timer 27 times out. With this ventilation system, a notification can be given at the set time by the kitchen timer 27, so that the cook can know that the set time has elapsed. Furthermore, by notifying the user via the mobile terminal 30, even a cooker who is away from the cooking appliance 10 can know that the set time has elapsed. Therefore, a cooker who is away from the cooking appliance 10 can immediately return to the cooking appliance 10 and perform the next cooking task.

[0055] A second embodiment of the ventilation system of the present invention will be described. The cooking device 10 is provided with a temperature detection unit that detects the temperature of the food being cooked in the cooking device 10. The temperature detection unit 15 on the cooking device side is a temperature detection unit that detects the temperature of the food being cooked, but a temperature detection unit that detects the temperature of the food may be provided separately from the temperature detection unit 15. Also, a temperature detection unit that detects the temperature of the food may be provided in the range hood 20. In other words, the ventilation system 1 may be provided with a temperature detection unit that detects the temperature of the food being cooked in the cooking device 10. The heating state judgment unit is of a first configuration, and the heating cooker control unit 12 is configured so that when it is determined that the heating cooker 10 is in a heating state, the heating cooker control unit 12 outputs a prior notification if the detected temperature sent from the temperature detection unit 15 is a predetermined temperature. The predetermined temperature is a temperature just below the temperature commonly used in cooking.

[0056] The configuration will be explained together with the operation. When cooking is started, the temperature detected by temperature detector 15 on the cooking appliance side reaches a predetermined temperature, and cooking appliance controller 12 determines that cooking appliance 10 is in a heating state, as explained above. Then, when the detected temperature of the temperature detection unit 15 reaches a predetermined temperature, the heating cooker control unit 12 outputs an advance notification, and the advance notification is sent 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 controls the display unit 31 and / or the speaker 32 to give an advance notification that is a notification in response to the advance notification. In other words, the condition is satisfied when the temperature detected by temperature detection unit 15 is a predetermined temperature.

[0057] With this ventilation system, the cooker can know when the food being cooked in the cooking device 10 has reached a predetermined temperature. For example, if the specified temperature is set to 80°C, which is the temperature before water boils, the cook can know that the water will boil a little after the advance notification from the mobile terminal 30, and can move on to the next cooking step with plenty of time after the notification from the mobile terminal 30. The predetermined temperature is preset, and the cook does not need to set it each time cooking is performed, or the cook may be allowed to set the predetermined temperature.

[0058] A third embodiment of the ventilation system of the present invention will be described. As in the second embodiment, the ventilation system 1 is provided with a temperature detector that detects the temperature of the food being cooked in the cooking device 10. The cooking device 10 allows the heating temperature of the food to be set. For example, the cooking device operation unit 13 can be operated to set the heating temperature of the food in the cooking device control unit 12, the temperature can be set in an automatic cooking mode, in a water boiling mode, or by a notification from the mobile terminal 30. The heating state determination unit is of a first configuration, and the heating cooker control unit 12 is configured to output a prior notification when the detected temperature sent from the temperature detection unit 15 when the heating cooker 10 is determined to be in a heating state is a specified temperature lower than the set heating temperature of the cooking item.

[0059] The configuration will be explained together with the operation. When the heating temperature of the food to be cooked is set and cooking begins, the temperature detected by the temperature detection unit 15 on the cooking appliance side reaches a predetermined temperature, and as explained above, the cooking appliance control unit 12 determines that the cooking appliance 10 is in a heating state. The cooking appliance control unit 12 then compares the detected temperature of the temperature detection unit 15 with the set temperature, and when the detected temperature of the temperature detection unit 15 becomes a temperature that is lower than the set heating temperature of the food by a specified temperature, the cooking appliance control unit 12 outputs an advance notification, and this advance notification is sent to the mobile terminal control unit 33 via the cooking appliance communication unit 14, the range hood communication unit 25, and the mobile terminal communication unit 35. The mobile terminal control unit 33 controls the display unit 31 and / or the speaker 32 to give an advance notification that is a notification in response to the advance notification. In other words, the condition is met when the temperature detected by temperature detection unit 15 is lower by a specified temperature than the set heating temperature of the food to be cooked.

[0060] With this ventilation system, the mobile terminal 30 issues an advance warning when the actual temperature of the food being cooked is a specified temperature lower than the set temperature, allowing the cook to carry out other tasks with plenty of time until the advance warning is issued by the mobile terminal 30, and then, once the temperature reaches the heating temperature, cooking (the next step) can begin immediately. The difference between the actual temperature of the food and the set temperature is preferably such that there is enough time for the cook to move on to the next step from the time the advance notification from the mobile terminal 30 is made until the temperature reaches the heating temperature, and it is preferable that the time difference is set to a temperature that allows a margin of, for example, about 3 minutes. Also, this specified temperature may be set by the cook.

[0061] A fourth embodiment of the ventilation system of the present invention will now be described. The ventilation system 1 has an automatic cooking mode. The automatic cooking mode is set by the cooker 10, but can also be set by the mobile terminal 30. By setting the automatic cooking mode, the cooking device 10 may perform automatic cooking by itself, or the range hood 20 may perform ventilation operation in conjunction with the automatic cooking of the cooking device 10. In the automatic cooking mode, the heating time for the food to be cooked is set as a specified time. The heating state determination unit has the first configuration, and the cooking device control unit 12 has a configuration for performing the operation described below.

[0062] The configuration will be explained together with the operation. When cooking in the automatic cooking mode, a specified time determined in the automatic cooking mode and a predetermined time are set in the cooking device control unit 12. When cooking starts, the temperature detected by the temperature detector 15 on the cooking device side reaches a predetermined temperature, and the cooking device controller 12 determines that the cooking device 10 is in a heating state as described above, and starts counting the time since the determination. The counted time is the heating time of the food to be cooked. Then, when the time difference between the counted time and the specified heating time reaches a predetermined time, that is, when the counted time reaches a time shorter than the specified time by a predetermined time, the cooking device control unit 12 outputs a prior notification.

[0063] The advance notice output from the cooking appliance control unit 12 is sent to the mobile terminal control unit 33 via the cooking appliance communication unit 14, the range hood communication unit 25, and the mobile terminal communication unit . The mobile terminal control unit 33 controls the display unit 31 and / or the speaker 32 to give an advance notification that is a notification in response to the advance notification. In other words, the condition is met when the difference between the cooking time and the specified time for the cooking food is a predetermined time.

[0064] With this ventilation system, when the heating time of the food to be cooked is set as a specified time in the automatic cooking mode, an advance warning is given on the mobile terminal 30 when the heating time of the food to be cooked is a specified time shorter than the specified time, so that the cook can perform other tasks with plenty of time until the advance warning on the mobile terminal 30, and can immediately begin cooking (the next process) when the specified time arrives after the advance warning on the mobile terminal 30. The predetermined time is preferably set to a time that allows the cook to move on to the next step with ease between the time when the mobile terminal 30 notifies the cook and the time when the specified time has elapsed, and is preferably about 3 minutes. The predetermined time may also be set by the cook.

[0065] A fifth embodiment of the ventilation system of the present invention will now be described. The ventilation system of this embodiment is a ventilation system in which a counter is added to the ventilation systems of the first to fourth embodiments. A counter for counting time is provided in the control unit constituting the heating state determination unit, and a predetermined time is set. The heating state determination unit has the first configuration, and a counter for counting time is provided in the cooking device control unit 12, and the predetermined time is set.

[0066] The configuration will be explained together with the operation. After cooking is started in the cooking device 10, the cooking device control unit 12 starts counting the counter when it determines that the cooking device 10 is in a heating state. The count time of the counter is the time from the start of cooking. The cooking device control unit 12 compares the count time of the counter with the set predetermined time, and when the count time matches the predetermined time, the cooking device control unit 12 outputs a count notification. In other words, the condition is satisfied when the cooking time of the food reaches the predetermined time. The count notification is sent from cooking appliance communication unit 12 to mobile terminal control unit 33 via range hood communication unit 25 and mobile terminal communication unit 35. Mobile terminal control unit 33 controls display unit 31 and / or speaker 32 to give a count notification, which is a notification in response to the count notification. For example, it may give a notification that the cooking time by cooking appliance 10 has reached a predetermined time. With this ventilation system, the cook can be made aware that a certain time has elapsed since the start of cooking, and can therefore prevent the food from being overcooked or burned. The certain time is preferably a time that can be notified before the food is overcooked or burned, and is preferably about 15 minutes, for example. The certain temperature may also be set by the cook.

[0067] A sixth embodiment of the ventilation system of the present invention will now be described. The ventilation system of this embodiment is a ventilation system in which a counter is added to the ventilation system of the fifth embodiment, to which a counter is added, and a function of resetting the counter is added. Cooking device control unit 12, which is a control unit constituting the heating state determination unit, is configured to reset the count of the counter when it sends a count notification. The count may be reset only when the count is notified, but the count may also be reset when other notifications are made. In this ventilation system, the counter is reset by sending a notification to the mobile terminal 30, so notifications can be sent to the mobile terminal 30 continuously.

[0068] A seventh embodiment of the ventilation system of the present invention will be described. The ventilation system of this embodiment is a ventilation system in which a function is added to the ventilation system of the fifth embodiment in which a counter is added. The heating state determination unit is configured as the first configuration, and the cooking device control unit 12 is configured to output a count notification and a notification set by the cooker other than the count notification. The notifications set by the cooker other than the count notification include a timer notification based on a time set by a timer function in the ventilation system of the first embodiment, an advance notification based on the temperature of the food in the ventilation systems of the second and third embodiments, and an advance notification based on the heating time of the food in the automatic adjustment mode in the ventilation system of the fourth embodiment.

[0069] The heating cooking unit control unit 12, which is a control unit that constitutes the heating status determination unit, has a function of recognizing the timing to send the count notification and the timing to send a notification set by the cook other than the count notification, and is configured to not send the count notification and to send the notification set by the cook other than the count notification if the timing to send the count notification comes earlier than the timing to send a notification set by the cook other than the count notification, i.e., if the count notification is to be sent first, it is configured to not send the count notification and to send the notification set by the cook other than the count notification.

[0070] In a ventilation system of this configuration, if a count notification is sent before a notification other than the count notification set by the cook, there is a possibility that the count notification will be mistaken for an alert due to a notification other than the count notification set by the cook. However, by not sending the count notification, there is no risk that the cook will mistakenly mistake an alert due to the count notification for an alert due to a notification other than the count notification set by the cook. For example, the mobile terminal 30 will not notify the user of the count until the time set by the cook in the kitchen timer function has elapsed, so that it is possible to prevent unnecessary notifications from being made before the time intended by the cook has elapsed. In other words, the time intended by the cook is the set time of the kitchen timer 27.

[0071] An eighth embodiment of the ventilation system of the present invention will now be described. The ventilation system of this embodiment is configured such that the predetermined time to be compared with the counted time of the counter in the ventilation system of the fifth embodiment in which a counter is added can be set arbitrarily. For example, the predetermined time set in the cooking device control unit 12 can be changed by operating the cooking device operation unit 13 . With this ventilation system, the time interval between the start of cooking and the sending of the counter notification can be set to any time, and the count notification can be sent at an appropriate time interval depending on the type of cooking.In addition, by setting the time according to the cook's usual cooking habits and behavioral patterns, the counter notification can be optimally sent to the cook.

[0072] A ninth embodiment of the ventilation system of the present invention will be described. As shown in Fig. 1, range hood 20 is provided with a human presence sensor 28 that detects the presence or absence of a person near range hood 20, and a counter 29 that counts the time during which human presence sensor 28 does not detect a person. Human presence sensor 28 may be provided in a location other than range hood 20, such as in a wall near cooker 10 or range hood 20. In other words, ventilation system 1 is provided with human presence sensor 28 and counter 29. Counter 29 can also serve as the counter that counts a set predetermined time, as explained above. Also, instead of counter 29, a configuration may be adopted in which a control unit (cooker control unit 12 or range hood control unit 24) has a counting function. The heating state determination section is configured as the first configuration, and human detection information from the human sensor 28 is input to the cooking device control section 12, which is a control section constituting the heating state determination section, and a predetermined time is set.

[0073] The configuration will be explained together with the operation. When cooking starts and the temperature detected by the temperature sensor 15 reaches a predetermined temperature, the cooking device control unit 12 determines that the cooking device 10 is in a heating state. When this determination is made, the counter 29 starts counting. When the human presence sensor 28 detects a person near the range hood 20, that person detection information is sent to the cooking appliance control unit 12, and the count time of the counter 29 is reset. If the human presence sensor 28 does not detect a person near the range hood 20 thereafter, the counter 29 starts counting again. By repeating this operation, when the count time of counter 29 reaches the set predetermined time, cooking device control unit 12 outputs a count notification. This count notification is sent to mobile terminal 30 in the same manner as described above, and mobile terminal 30 issues a count notification in response to the count notification in the same manner as described above. In other words, the condition is met when no one is present near the range hood 20 for a predetermined period of time.

[0074] In this way, the mobile terminal 30 issues a count notification when no one has been near the range hood 20 for a specified time, so that the count notification can be sent to a cook who is not near the range hood 20, to inform the cook that he or she has been away for a specified time during cooking. It is also possible for counter 29 to continue counting even when human presence sensor 28 detects a person, store the count time of counter 29 when human presence sensor 28 no longer detects a person, and when the count time from that point reaches a predetermined time, determine that the predetermined time has passed since there was no person near range hood 20, and send a count notification to mobile terminal 30. In this case, if a person is detected near range hood 20 before the predetermined time has passed since there was no person near range hood 20, the memory of the count time of counter 29 when it no longer detected a person is deleted, and when it no longer detects a person again, store the count time of counter 29, and determine whether the predetermined time has passed.

[0075] The operation of the ventilation system in which the ventilation systems of the fifth, sixth, seventh and ninth embodiments are combined will be described with reference to the flow chart shown in FIG. The temperature of the cooking device 10 is detected by the temperature detection unit 15 on the cooking device side, and the detected temperature is sent to the cooking device control unit 12. When a predetermined temperature is reached (YES in step 101), it is determined that the cooking device is in a heating state (step 102), and a counter starts counting (step 103). If the cooking appliance 10 is not in a heating state (NO in step 104), it is determined that the cooking appliance 10 is in a heating stop state (step 105), and the operation ends. If the cooking device 10 is in a heating state (YES in step 104) and the human presence sensor 28 detects a person (YES in step 106), the count time of the counter is reset (step 107).

[0076] If the human presence sensor 28 does not detect a person (NO in step 106), it continues counting, and when the counter's count time reaches a predetermined time (YES in step 108), it outputs a notification, and if that notification is later than other set notifications (NO in step 109), it sends the notification to the mobile terminal 30, sends the notification to the mobile terminal 30 (step 110), and resets the counter's count time (step 111). If the notification is before other set notifications (YES in step 109), sending of the notification to the mobile terminal 30 is stopped (step 112), and the count time of the counter is reset (step 111).

[0077] A tenth embodiment of the ventilation system of the present invention will now be described. The heating state determination unit has a first configuration. The heating cooker control unit 12 of the heating cooker 10 is provided with a position information memory unit that stores the position of the heating cooker 10, and the mobile terminal 30 is provided with a position information detection unit 36 ​​that detects position information by GPS, and a distance detection means is configured to detect the distance between the heating cooker 10 and the mobile terminal 30 from the position of the heating cooker 10 stored in the position information memory unit and the position information of the mobile terminal 30 detected by the position information detection unit 36. In addition, the distance detection means may be configured to provide a position information memory unit in the range hood control unit 24 of the range hood 20 that stores the position of the range hood 10, and detect the distance between the range hood 20 and the mobile terminal 30 from the position of the range hood 10 stored in the position information memory unit and the position information of the mobile terminal 30 detected by the position information detection unit 36.

[0078] The distance detection means is not limited to this configuration, and can be configured to communicatively connect the mobile terminal communication unit 35 of the mobile terminal 30 and the range hood communication unit 25 of the range hood 20, and estimate the distance between the range hood 10 and the mobile terminal 30 from the communication strength between the mobile terminal 30 and the range hood 20. In addition, the mobile terminal communication unit 35 of the mobile terminal 30 and the heating cooker communication unit 14 of the heating cooker 10 can be communicatively connected, and the distance between the heating cooker 10 and the mobile terminal 30 can be estimated from the communication strength between the mobile terminal 30 and the heating cooker 10.

[0079] The configuration will be explained together with the operation. A fixed distance is set in the heating cooker control unit 12, which is a control unit that constitutes the heating state determination unit, and the distance detected by the distance detection means is input to the heating cooker control unit 12, so that the fixed distance set by the heating cooker control unit 12 can be compared with the detected distance. When the cooking device control unit 12 determines that the cooking device 10 is in a heating state, the cooking device control unit 12 outputs an exit notification when the detected distance exceeds a set certain distance. The exit notification output by the cooking appliance control unit 12 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. The mobile terminal control unit 33 controls the display unit 31 and / or the speaker 32 to issue an exit notification that is a notification in response to the exit notification. In other words, the condition is satisfied when the mobile terminal 30 is moved away from the cooking appliance 10 and the range hood 20 by one distance or more.

[0080] For example, when the distance detection means detects the distance between the cooking appliance 10 and the mobile terminal 30, an exit notification is given to the mobile terminal 30 that is more than a certain distance away from the cooking appliance 10, and when the distance detection means detects the distance between the range hood 20 and the mobile terminal 30, an exit notification is given to the mobile terminal 30 that is more than a certain distance away from the range hood 20. To summarize the ventilation system of this embodiment, the ventilation system is equipped with a distance detection means for detecting the distance between the mobile terminal 30 and the cooking appliance 10 or the distance between the mobile terminal 30 and the range hood 20, and the control unit constituting the heating state determination unit is configured to send an exit notification to the mobile terminal 30 when the heating state determination unit determines that the cooking appliance 10 is in a heating state and the distance detected by the distance detection means exceeds a certain distance.

[0081] With this ventilation system, when a cook moves a certain distance or more away from the cooking appliance 10 or the range hood 20 while holding the mobile terminal 30, the mobile terminal 30 notifies the cooker of the departure, so that the cooker can realize that he or she has moved a certain distance or more away from the cooking appliance 10 or the range hood 20 during cooking. The fixed distance is preferably the distance at which the cook leaves the house, and is about 10 m. However, since the structure and size of houses are different, and the distance at which the cook leaves the house also differs, the fixed distance may be set by the cook at will.

[0082] An eleventh embodiment of the ventilation system of the present invention will now be described. The heating state determination unit has a first configuration. The range hood 20 is provided with a human presence sensor that detects the presence or absence of a person near the range hood 20. The human presence sensor may be provided in the cooking appliance 10, or may be provided around the cooking appliance 10 or around the range hood 20. In other words, it is sufficient that the ventilation system 1 is provided with a human presence sensor. The human presence sensor is a camera, an infrared sensor, or the like. Human detection information from the human sensor is input to the cooking device control unit 12, which is a control unit that controls the heating state determination unit.

[0083] The heating cooker control unit 12 is configured to notify the mobile terminal 30 when a condition is met (i.e., when notifying the mobile terminal 30) when it is determined that the heating cooker 10 is in a heating state, and when no human detection information is input from the human presence sensor. The condition being satisfied is the same as any one of the ventilation systems of the first to fifth embodiments, the ninth and the tenth embodiments. When sending a notification to the mobile terminal 30, if information on human detection is input from the human presence sensor, the notification may be sent to the cooking appliance 10 or the range hood 20 so that the cooking appliance 10 or the range hood 20 issues an alert, or no notification may be sent and no alert may be issued. With this configuration, when the cook is near the range hood, the mobile terminal 30 will not issue a notification. In order for the cooking appliance 10 and the range hood 20 to give an alert, a function similar to that of an alert unit, similar to that of the mobile terminal 30, is provided in the cooking appliance 10 and the range hood 20 so that an alert is given when a notification is made.

[0084] The operation of the ventilation system combining the fifth, sixth and tenth embodiments will be described with reference to the flow chart of FIG. The temperature of the cooking device 10 is detected by the temperature detection unit 15 on the cooking device side, and the detected temperature is sent to the cooking device control unit 12. When a predetermined temperature is reached (YES in step 201), it is determined that the cooking device is in a heating state (step 202), and a counter starts counting (step 203). If the cooking appliance 10 is not in a heating state (NO in step 204), it is determined that the cooking appliance 10 is in a heating stop state (step 205), and the operation ends.

[0085] If the cooking device 10 is in a heating state (YES in step 204), the counter count time is the same as the predetermined time (YES in step 206), and the human presence sensor does not detect a person (NO in step 207), a notification is sent to the mobile terminal 30 (step 208), and the counter count time is reset (step 209). If the human sensor detects a human (YES in step 207), the range hood 20 is notified and the range hood 20 issues an alarm (step 210), and the count time of the counter is reset (step 209).

[0086] A twelfth embodiment of the ventilation system of the present invention will now be described. In the ventilation system of this embodiment, the cooking appliance 10 and / or the range hood 20 can be controlled by operation instructions transmitted from the mobile terminal 30, and thus can be operated by the mobile terminal 30. The heating state determination unit has a first configuration, and the heating cooker control unit 12, which is the control unit of the heating state determination unit, has a function of counting the elapsed time from when it is determined that the heating cooker 10 has entered a heating state, and a predetermined time is set.The unit is configured to output a notification that heating is continuing and an operation notification when the elapsed time from when it is determined that the heating cooker 10 has entered a heating state reaches the set predetermined time. The notification that heating is continuing is issued when a condition is satisfied while the cooking appliance 10 is determined to be in a heating state. The operation notification is a notification requesting an operation for outputting an operation instruction for the range hood 20 and / or the cooking appliance 10 from the mobile terminal 30.

[0087] The mobile terminal 30 is configured to be capable of outputting operation instructions for the range hood 20 and / or the cooking appliance 10, and to be able to operate the range hood 20 and / or the cooking appliance 10 using the mobile terminal 30. For example, a range hood operation app and / or a cooking appliance operation app can be installed on the mobile terminal 30, so that operation notifications for the range hood 20 and / or cooking appliance 10 can be input to the mobile terminal control unit 33 by operating the mobile terminal operation unit 34. Operation instructions for the range hood 20 and / or cooking appliance 10 inputted to the mobile terminal control unit 33 are sent from the mobile terminal communication unit 35 via the range hood communication unit 25 and / or cooking appliance communication unit 14 to the range hood control unit 24 and / or cooking appliance control unit 12, and the range hood control unit 24 operates the range hood 20 and / or the cooking appliance control unit 12 operates the cooking appliance 10.

[0088] The operation instructions for the range hood 20 include maintaining the current state, changing the air volume of the blower 21, stopping the blower 21, setting a timer, and the like. The operation instructions for the cooking device 10 include maintaining the current state, changing the heating intensity, stopping the heating state, setting a timer, and the like. Next, the operation will be described. When cooking starts and the temperature detected by the temperature sensor 15 reaches a predetermined temperature, the cooking device control unit 12 determines that the cooking device 10 is in a heating state. When this determination is made, counting of the elapsed time is started. After the counted elapsed time reaches a set predetermined time, the cooking appliance control unit 12 outputs a notification that heating is continuing and an operation notification requesting operation of the range hood 20 and / or the cooking appliance 10.

[0089] This notification that heating is continuing and the operation notification are sent from the heating cooker communication unit 14 via the range hood communication unit 25 and 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 speaker 32 to notify that heating is continuing and to give an alert in response to the operation notification. For example, a notification that cooking is in progress, and a notification to operate the range hood 20 and / or the cooking unit 10 are given. To summarize the ventilation system of this embodiment, the cooking appliance control unit 12, which is the control unit of the heating state determination unit, is configured to send a notification that heating is continuing and an operation notification to operate the range hood 20 and / or the cooking appliance 10 to the mobile terminal 30 a predetermined time after the heating state determination unit determines that the cooking appliance 10 has entered a heating state.

[0090] With a ventilation system having this configuration, the range hood and / or cooking appliance can be operated using the mobile terminal 30, so that appropriate measures can be taken even if a cook cannot immediately rush to the cooking area. For example, when a cook leaves the cooking appliance 10 during cooking to clean the house or take a break in the living room, the cook can become aware that cooking is still in progress because a notification that heating is continuing is issued after a predetermined time has elapsed since the start of cooking. This makes it possible for a user to become aware of the passage of time if they are concentrating on cleaning and have not noticed that time has passed, and also serves as a reminder that cooking has been in progress if they have forgotten that cooking has been in progress. This allows the cooker to take appropriate action by operating the mobile terminal 30 to operate the range hood 20 and / or the cooking appliance 10 from a remote location without rushing to the cooking appliance 10. Furthermore, the operation notification may be sent to the mobile terminal 30 not only as a notification that heating is continuing when the counted elapsed time reaches a set predetermined time, but also together with other notifications that heating is continuing.

[0091] A thirteenth embodiment of the ventilation system of the present invention will now be described. Even if the range hood 20 and / or cooking appliance 10 can be operated and instructed by the mobile terminal 30, as in the ventilation system of the twelfth embodiment, if the user forgets to operate the range hood 20 and / or cooking appliance 10 or does not notice the notification that the cooking appliance 10 is still heating, the cooking appliance 10 will remain in a heating state. The ventilation system of the 13th embodiment is made to solve this problem by adding to the cooking appliance control unit 12 in the ventilation system of the 12th embodiment a function for determining whether an operation instruction for the range hood 20 and / or cooking appliance 10 has been received, and a function for notifying the mobile terminal 30 that heating is continuing again when no operation instruction has been received from the mobile terminal 30 a certain time has elapsed since sending an operation notification for the range hood 20 and / or cooking appliance 10 to the mobile terminal 30.

[0092] For example, the heating cooker control unit 12 is configured to have a counting function that counts the time after notifying the mobile terminal 30, a function that determines whether an operation instruction has been received from the mobile terminal 30, and a function that notifies that heating is continuing when it is determined that no operation instruction has been received after counting a certain amount of time. As a result, if the heating cooker control unit 12 does not receive an operation instruction from the mobile terminal 30 even after a certain time has elapsed since sending a notification that heating is continuing and an operation notification to the mobile terminal 30, the heating cooker control unit 12 sends a notification that heating is continuing to the mobile terminal 30 again. With a ventilation system of this configuration, if a cook has not noticed the previous notification, it can be made easier for the cook to notice it.

[0093] A fourteenth embodiment of the ventilation system of the present invention will now be described. As in the ventilation system of the thirteenth embodiment, even if the portable terminal 30 notifies the cooker that heating is continuing again, if the cook does not notice that heating is continuing, the heating cooking 10 remains in the heating state. The ventilation system of the 14th embodiment is made to solve this problem by adding to the cooking appliance control unit 12 in the ventilation system of the 13th embodiment a function of counting the time since the notification that heating is continuing is sent again, and a function of automatically stopping the heating of the cooking appliance 10, so that the ventilation system automatically stops the heating of the cooking appliance 10 if no operation instructions for the range hood 20 and / or cooking appliance 10 are received from the mobile terminal 30 within a certain period of time after the notification that heating is continuing is sent again.

[0094] In the ventilation system of this configuration, if the cooker is unable to know the notification due to some factor, the heating of the cooking device 10 is automatically stopped, so that the food to be cooked can be protected and a fire can be prevented. In addition, after the heating of the cooking device 10 is stopped, a notification that the heating has been stopped can be sent to the mobile terminal 30. This allows the cooker to be informed that the heating has already been stopped, for example, when he or she notices that the notification has been made later. In the twelfth to fourteenth embodiments, the certain time for making the notification or stopping the heating can be the same time or different times. For example, the time can be shortened in the order of the time until the first notification that heating is continuing, the time from the first notification that heating is continuing to the second notification that heating is continuing, and the time from the second notification that heating is continuing to the automatic stopping of heating.

[0095] A fifteenth embodiment of the ventilation system of the present invention will now be described. The ventilation system of this embodiment is configured to send a temperature notification displaying cooking food temperature information when sending a notification to the mobile terminal 30, like the ventilation systems of the first to fourteenth embodiments. The heating system 1 is provided with a temperature information detection means for detecting temperature information of the food being cooked in the cooking device 10. Temperature detector 15 on the cooking device side detects the temperature of the food being cooked, and is therefore temperature information detection means. The temperature detector 26 on the range hood side detects the temperature above the cooking appliance 10 and is therefore capable of detecting the temperature of the food being cooked, and is therefore a temperature information detector. In addition to the temperature detector 15 on the cooking device side and the temperature detector 26 on the range hood side, a device for detecting the temperature of the food to be cooked may be provided as the temperature information detector.

[0096] The heating state determination section is of the first configuration, and cooking food temperature information detected by the temperature information detection section is input to cooking device control section 12, which is the control section of the heating state determination section. The configuration will be explained together with the operation. As described above, the cooking device control unit 12 determines that the cooking device 10 is in a heating state, and sends a notification to the mobile device 30 when the conditions are met, as in the ventilation systems of the other embodiments, and when sending the notification, sends a temperature notification that displays the input cooking food temperature information. The method of sending the notification to the mobile device 30 is the same as in the ventilation systems of the other embodiments. The mobile terminal 30 issues a notification according to the received notification and a notification according to the received temperature information. The method of notification is the same as in the ventilation systems of the other embodiments. If the temperature information is a temperature, the temperature is displayed numerically on the display unit 31 to notify the user. With a ventilation system of this configuration, the cook can know the cooking status from the temperature information of the food being cooked, making it easier for the cook to make appropriate cooking decisions.

[0097] The operation of the ventilation system obtained by combining the ventilation systems of the twelfth to fifteenth embodiments will be described with reference to the flow chart of FIG. The temperature detection unit 15 on the cooking appliance side detects the temperature of the cooking appliance 10 and sends the detected temperature to the cooking appliance control unit 12. When a predetermined temperature is reached (YES in step 301), it is determined that the cooking state has been reached (step 302). If the conditions are met (YES in step 303), cooking item temperature information is obtained (step 304) and, after a predetermined time has elapsed, a notification that heating is continuing, an operation notification, and cooking item temperature information are sent to the mobile terminal 30, and the mobile terminal 30 notifies the user that heating is continuing, the operation notification, and the cooking item temperature status (step 305). If there is no instruction to operate the cooking appliance 10 (NO in step 306), after a certain time has elapsed (YES in step 307), a notification that heating is continuing is sent again to the mobile terminal 30 (step 308), and the mobile terminal 30 notifies again.

[0098] If there is no instruction to operate the cooking appliance 10 after the mobile terminal 30 issues the notification again (NO in step 309) and a certain time has elapsed (YES in step 310), an instruction to stop heating the cooking appliance 10 is issued (step 311), and heating of the cooking appliance 10 is stopped. If there is an instruction to operate the cooking device 10 (YES in step 306, YES in step 309), the cooking device operation section 13 is operated to carry out the operation of the cooking device 10 (step 312).

[0099] A sixteenth embodiment of the ventilation system of the present invention will now be described. The ventilation system of this embodiment is a ventilation system of each embodiment to which is added a function that allows a control unit (heating cooker control unit 12 or range hood control unit 24) to select whether or not to send a notification to a mobile terminal. The heating state determination unit has a first configuration, and the heating cooker control unit 12, which is the control unit of the heating state determination unit, is provided with a notification mode in which a notification is sent to the mobile terminal 30 and a non-notification mode in which no notification is sent to the mobile terminal 30, so that either the notification mode or the non-notification mode can be selected. For example, by operating the cooking device operation unit 13, a notification mode or a non-notification mode can be selected.

[0100] By selecting the non-notification mode, even if the cooking device 10 is in a heating state and satisfies the conditions, no notification is sent to the mobile terminal 30, and the mobile terminal 30 does not report the situation. This prevents the cook from receiving any notification that the cook does not want, which is not bothersome for the cook. For example, when cooking while carrying the mobile terminal 30, the notification can be prevented, so that it is not bothersome. If the notification mode is selected, a notification can be sent to the mobile terminal 30 as described above, and the mobile terminal 30 can then notify the user.

[0101] A seventeenth embodiment of the present invention will now be described. The ventilation system of this embodiment is a ventilation system similar to the 16th embodiment, but capable of sending multiple different notifications, and when a notification mode is selected, only the notification selected from the multiple notifications is sent. That is, the ventilation system is configured to be capable of sending a plurality of different notifications, and in the notification mode, sends only a notification selected from the plurality of notifications. The heating state determination unit has a first configuration, and a notification mode and a non-notification mode are set in the heating cooker control unit 12, which is the control unit of the heating state determination unit, and multiple control patterns for sending notifications are set in the notification mode, making it possible to send multiple notifications. The cook can select either a notification mode or a non-notification mode, and if the cook selects the notification mode, a control pattern is selected and only the selected notification is sent from a number of notifications.

[0102] The notifications include notifications based on a kitchen timer, notifications based on cooking temperature, notifications based on the heating temperature of the food, notifications based on automatic cooking mode, notifications based on cooking time using a counter, notifications based on the presence or absence of people near the range hood using a human presence sensor, and notifications based on the distance between the mobile device and the cooking appliance or range hood. The control patterns include control for sending notifications in the first, second, third, fourth, fifth, ninth, tenth, eleventh, twelfth and fifteenth embodiments of the present invention. That is, the ventilation system of this embodiment is configured to be capable of performing a plurality of notification operations of each embodiment of the present invention, and is configured to select one of the operations and send a notification.

[0103] The selection of the notification is made by a cook or the like sending a notification selection instruction to the cooking device control unit 12, and the cooking device control unit 12 notifies the mobile terminal 30 when it determines to make the selected notification. In a ventilation system having this configuration, the mobile terminal 30 issues a notification using the selected notification, but does not issue notifications using other notifications that are not selected, so that the cook does not receive unnecessary notifications and can receive only necessary notifications. 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 that control unit. Furthermore, 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. Furthermore, a plurality of embodiments may be arbitrarily combined to form one embodiment. [Explanation of symbols]
