When the monitoring sensor 21 is equipped with, for example, an infrared sensor that detects the temperature of the surface of the food instead of the camera 31, the comparison unit 34 determines the surface temperature of the food before cooking and the surface of the food after cooking starts. The temperature is compared with the temperature, and temperature change data indicating the temperature change of the food material is output.
[0025]
FIG. 6 is a configuration diagram showing the inside of the control circuit 17. In the figure, reference numeral 41 denotes a pattern setting unit that stores a color change pattern for each dish and receives designation of a dish to be cooked this time from a user; A progress grasping section 43 for comparing the color change pattern of the dish received by the above with the color change data output from the monitoring sensor 21 to grasp the progress of the dish, 43 is a magnetic field generating coil 16 according to the progress of the dish. The controller 44 controls the intensity of the high-frequency current supplied to the IH cooker, and when the cooking by the IH cooker reaches a certain stage, activates the microwave oven 50 connected to the IH cooker via a network. When receiving a signal indicating that no human body is present, the count value is incremented at predetermined time intervals, while the presence of a human body from the human body detection sensor 23 is detected. When the count value is reset, the count value is reset. When the count value reaches a count value corresponding to a preset period, the count unit that outputs a high-frequency current supply stop command is provided by a microwave oven (others). Is a server that holds a color change pattern of various dishes and a thermal power adjustment pattern.
When the pattern setting unit 41 stores, for example, a temperature change pattern for each dish instead of a color change pattern for each dish and receives temperature change data from the monitoring sensor 21, the temperature change pattern and the temperature change data are compared. The progress of cooking may be grasped by comparison.
[0026]
Next, the operation will be described.
The monitoring sensor 21 is equipped with an infrared sensor for detecting the temperature of the surface of the food, a camera for imaging the surface of the food, and the like. As shown in FIG. If so, the camera image of the food before cooking is compared with the camera image of the food after the start of cooking, the color change of the food is monitored, and color change data indicating the color change of the food is output.
When the power is turned on, the pattern setting unit 41 acquires a plurality of predetermined color change patterns of cooking from the server 51 via the network, and sets them in a storage area (not shown).
When the pattern setting unit 41 does not have the cooking color change pattern designated by the user, the pattern setting unit 41 acquires the corresponding color change pattern from the server 51 via the network and sets the pattern in the storage area.
[0027]
When receiving the color change data from the monitoring sensor 21 after the pattern setting unit 41 receives the designation of the dish to be cooked this time from the user, the progress situation grasping unit 42 of the control circuit 17 receives the color change data and the dish to be cooked this time. And grasp the progress of cooking by comparing the color change patterns.
Then, when the progress situation grasping section 42 grasps the progress situation of the dish, the control section 43 of the control circuit 17 controls the high-frequency current supplied to the magnetic field line generating coil 16 according to the progress situation of the dish. For example, the heating power is adjusted according to the heating power adjustment pattern set according to the progress of the cooking.
[0028]
If the color change pattern corresponding to the current dish is not set, the progress grasping unit 42 detects the occurrence of scorching when the color of the food approaches black, and the control unit 43 generates the magnetic field lines. The supply of the high-frequency current to the coil 16 may be stopped. At this time, the progress situation grasping unit 42 may generate an alarm indicating occurrence of burning. Here, the color change of the food is monitored. However, if an odor sensor (for example, gas chromatography) is mounted as the monitoring sensor 21, the odor sensor monitors the change in odor and detects the occurrence of burning. You may make it detect.
If the color change pattern corresponding to the current dish is not set, the pattern setting unit 41 transmits the color change pattern or the heat power adjustment pattern corresponding to the current dish from the server 51 via a network such as the Internet. May be collected.
[0029]
Further, the control unit 43 of the control circuit 17 may activate another cooking appliance when the progress of the dish grasped by the progress grasping unit 42 reaches a preset situation.
For example, when cooking by the IH cooker reaches a certain stage, when the microwave oven 50 connected to the IH cooker and connected to the network is activated, if the cooking can be performed efficiently, at that time, When it reaches, the control unit 43 of the control circuit 17 starts the microwave oven 50. Note that such a situation may be set, for example, in a color change pattern.
[0030]
On the other hand, when receiving the data indicating, for example, the temperature of the surface of the food from the monitoring sensor 21, the control unit 43 determines that the higher the temperature of the surface of the food is, the more the exhaust accompanying cooking is increased, and The air purifier 13 is controlled so as to adjust the suction amount.
This makes it possible to efficiently purify exhaust gas accompanying cooking without using wasteful electric power.
[0031]
In the IH cooker according to the second embodiment, a CCD camera 22 for photographing food is provided in addition to the monitoring sensor 21, and an image of the CCD camera 22 is output to the display unit 18.
As a result, the image of the food is displayed on the display unit 18, but the display unit 18 is removably stored inside the wall surface 12a of the self-supporting gantry 12, and even when the display unit 18 is detached from the wall surface 12a. When the operation content of the operation unit 15 or the display of the image of the CCD camera 22 is received (for example, the display unit 18 is configured to be able to receive a display signal from the operation unit 15 or the CCD camera 22 in a wireless manner) That is, when the operation unit 15, the CCD camera 22, and the display unit 18 are equipped with a wireless device as shown in FIG. 7), if the user takes the display unit 18 away from the IH cooker, , The state of foods, etc. can be grasped. Incidentally, the wall surface 12a of the free-standing gantry 12 is provided so as not to have irregularities, for example, to facilitate cleaning of oil stains and the like.
[0032]
In addition, from the viewpoint of ensuring safety, the control unit 43 of the control circuit 17 supplies the high-frequency current to the magnetic flux generating coil 16 when the human body detection sensor 23 does not continuously detect the presence of the human body for a preset period or more. Try to stop.
That is, when the count value of the count unit 44 reaches the count value corresponding to the preset period and receives the high frequency current supply stop command from the count unit 44, the control unit 43 Stop supplying.
[0033]
In the second embodiment, an example is described in which the progress of cooking is grasped by comparing the color change of the food with the color change pattern. However, the present invention is not limited to this. If it is installed, the progress of cooking may be grasped by monitoring the temperature change of the food. When a sound sensor is mounted as the monitoring sensor 21, the sound sensor collects cooking sounds and monitors an arbitrary frequency component constituting the cooking sounds to grasp the progress of the cooking. Is also good.
