(Configuration of external temperature detection means)
FIG. 4 is an external view of the external temperature detection means 30 according to the embodiment of the present invention.
FIG. 4A is a front view of the external temperature detection unit 30, and FIG. 4B is a side view of the external temperature detection unit 30.
Next, the configuration of the external temperature detection unit 30 according to the present embodiment will be described.
As shown in FIG. 4, the external temperature detection unit 30 is a sensor probe, and includes a device incorporation unit 31, a sensor unit 35, and a holding unit 37. And the to-be-heated container 10 is inserted | pinched with the sensor part 35 and the holding | suppressing part 37, and is attached. Further, the sensor unit 35 and the holding unit 37 are provided with a non-slip part 39 protruding in the direction of each other, and functions as an anti-slip when the heated container 10 is sandwiched and attached. The holding power is improved. Thus, since the external temperature detection means 30 is a structure attached to the to-be-heated container 10, since it can be used other than the specific to-be-heated container 10, it can respond to the to-be-heated container 10 of various shapes, High versatility.

  The sensor unit 35 has a rectangular shape (which may not be strictly rectangular), and is provided with a plurality of temperature sensor elements 36 in the longitudinal direction. When the sensor unit 35 is attached to the heated container 10, Temperature detection is possible. The temperature sensor element 36 detects the heat of the food in the heated container 10, and the temperature sensor element 36 in the portion where there is no food detects the heat of the heated container 10.

  The sensor unit 35 has a heat resistance up to 250 ° C. that is assumed as the temperature of the food, and is a flexible tube made of metal, silicone rubber, or the like that can be bent so as to correspond to the height direction of the container 10 to be heated. Metal shielded harnesses and silicone rubber are used. Further, silicone rubber is used for the holding portion 37 and the anti-slip portion 39 (of the sensor portion 35 and the holding portion 37). In addition, since the magnet (not shown) is provided inside the non-slip portion 39, it adheres to the metal heated container 10, and thus the holding force when the external temperature detecting means 30 is attached is improved.

  The device built-in unit 31 includes a power SW 32 for turning on / off the external temperature detecting means 30, an operation lamp 33 for displaying the on / off state of the power, and various information such as usage status and detected temperature for the user. Is displayed, and a fulcrum portion 38 that pivotally supports the holding portion 37 is provided.

  The operation lamp 33 corresponds to the “status display unit” in the present invention, and the display unit 34 corresponds to the “temperature display unit” in the present invention.

FIG. 5 is a functional block diagram of induction heating cooker 100 according to the embodiment of the present invention. In addition, the arrow in FIG. 5 has shown the flow of information.
As shown in FIG. 5, a sensor-side communication unit 301 and a sensor-side communication unit 301 that transmit temperature information detected by the temperature sensor element 36 of the sensor unit 35 to the main body-side communication unit 21 are provided inside the device incorporation unit 31. A sensor-side control unit 302 to be controlled and a power supply unit 303 for supplying power to each component unit are provided. Each of these components is sealed in a device-tight portion 31 in a watertight state.

  In addition, the device incorporating portion 31 has a structure that has heat resistance and impact resistance and does not shield radio waves. Specifically, it is formed of a material having impact resistance and a magnetic shielding effect (for example, aluminum). Further, it may be formed with a material that does not shield radio waves and has high heat resistance and high friction coefficient (for example, PPS, PC, silicone rubber, ceramics, etc.), and the surface may be coated with silicone rubber. In addition, a material that transmits radio waves other than metal may be used for at least a part of the device incorporation portion 31.

  The sensor side communication unit 301 performs bidirectional information communication with the main body side communication unit 21 arranged in the main body 1 of the induction heating cooker 100 under the control of the sensor side control unit 302. Information communication between the sensor side communication unit 301 and the main body side communication unit 21 is performed using, for example, a 2.4 GHz band wireless communication module. By using the wireless communication module, it is not necessary to provide a connector portion outside the external temperature detecting means 30, and it is possible to reduce the short circuit due to water immersion inside the external temperature detecting means 30. In addition, since the wiring is not required, it is possible to prevent the wiring from being caught by the handle of the heated container 10, and for example, the heating port 6 on the back side is easy to use, and the usability is improved. In addition, information can be transmitted to a 2.4 GHz Wi-Fi (IEEE802.11 standard) module provided in the home, and has expandability with external wireless communication devices.

  In addition, regarding a frequency band, you may use the specific low-power radio station communication module using the communication frequency band of the 900 MHz band or the frequency band below 300-500 MHz not only in 2.4 GHz band. For example, the frequency of the induction current in the induction heating cooker (IH cooking heater) uses a frequency band of 20 to 30 kHz, and the frequency of the electromagnetic wave in the microwave oven uses a frequency band of 2.45 GHz. For this reason, if it is a frequency of 900 MHz or 300-500 MHz band, it can communicate, without causing interference with other cooking appliances.

  In addition to the above, information communication may be performed using Bluetooth (registered trademark) or RFID (Radio Frequency Identifier). However, in the case of using RFID, since it is necessary to position the sensor side communication unit 301 and the main body side communication unit 21, a display indicating the arrangement position of the main body side communication unit 21 is performed on the top surface of the top plate 2. Information communication between the sensor side communication unit 301 and the main body side communication unit 21 is not limited to wireless communication, and may be wired communication using a cable.

  The sensor side control unit 302 controls each component of the external temperature detection unit 30. The sensor-side control unit 302 is configured by using hardware such as a circuit device that realizes the function, or is configured by an arithmetic device such as a microcomputer or a CPU and software executed thereon. The sensor-side control unit 302 performs A / D conversion on the detection signal from the temperature sensor element 36 of the sensor unit 35 and converts it to a temperature. Then, the converted temperature information is transmitted to the main body side communication unit 21 via the sensor side communication unit 301. For example, the highest temperature among the temperatures detected by the plurality of temperature sensor elements 36 is transmitted as temperature information.

  In the present embodiment, the sensor-side control unit 302 has a function of A / D-converting a detection signal from the temperature sensor element 36 of the sensor unit 35 and converting the detection signal into a temperature. A configuration provided separately from the control unit 302 may be employed.

  The temperature information transmission method is not limited to the above, and an average value of temperatures detected by the plurality of temperature sensor elements 36 may be transmitted as temperature information, or may be detected by the plurality of temperature sensor elements 36. A plurality of temperatures may be transmitted as they are as temperature information.

  When the sensor-side control unit 302 receives a state confirmation signal from the main body-side control unit 22, the sensor-side control unit 302 transmits a signal indicating that the power is on to the main body-side control unit 22 via the sensor-side communication unit 301. . The power supply unit 303 is a battery for supplying power to each component unit.

  As shown in FIG. 2, an infrared temperature sensor 25 is disposed near the heating coil 14 below the top plate 2 of the induction heating cooker 100. The infrared temperature sensor 25 detects infrared rays radiated from the bottom of the heated container 10 placed on the top plate 2 on the heating coil 14. In addition, it is desirable that a portion directly above the infrared temperature sensor 25 has a structure that does not shield infrared rays (for example, a cavity or a transmission material). The signal detected by the infrared temperature sensor 25 is input to the infrared temperature detector 250 shown in FIG. The infrared temperature detection unit 250 A / D converts the detection signal from the infrared temperature sensor 25 and converts it to a temperature. The temperature information converted by the infrared temperature detection unit 250 is input to the main body side control unit 22.

  Further, as shown in FIG. 2, a contact temperature sensor 26 such as a thermistor is in contact with the back surface of the top plate 2 on the back surface (the surface facing the heating coil 14) of the top plate 2 of the induction heating cooker 100. Is arranged. The contact-type temperature sensor 26 detects heat transferred from the heated container 10 to the top plate 2. The signal detected by the contact temperature sensor 26 is input to the contact temperature detector 260 shown in FIG. The contact-type temperature detection unit 260 performs A / D conversion on a detection signal from the contact-type temperature sensor 26 and converts it into a temperature. The temperature information converted by the contact-type temperature detection unit 260 is input to the main body side control unit 22.

  In the present embodiment, the infrared temperature detection unit 250 and the contact temperature detection unit 260 are provided separately from the main body side control unit 22, but may be provided in the same body.

The infrared temperature sensor 25 and the infrared temperature detector 250 correspond to the “second temperature detector” in the present invention, and the contact temperature sensor 26 and the contact temperature detector 260 in the present invention “the third temperature detector”. The external temperature detection means 30 corresponds to the “first temperature detection means” in the present invention.
The first temperature detection means, the second temperature detection means, and the third temperature detection means are collectively referred to as “temperature detection means”.

(Cooking operation)
Next, the heating operation of induction heating cooker 100 according to the present embodiment will be described.
The main body side control unit 22 of the induction heating cooker 100 has an automatic cooking mode in which a target temperature is set. The automatic cooking mode is a mode in which heating control of the heating coil 14 is performed so that the temperature acquired from the temperature detection means becomes the target temperature according to a control sequence set for each automatic cooking menu stored in advance in the storage unit 27. This is executed when the automatic cooking menu is selected.

  Examples of the automatic cooking menu include “boiled”, “boiled noodles”, “boiled water”, “baked food”, “fried food cooking”, and “temperature setting”. Each menu will be described in detail later, but at least one of the target temperature and the heating time is different from the other menus. In addition, the main body side control part 22 should just be the structure which performs at least 1 menu of these menus, Said automatic cooking menu is an example, It is not limited to the above.

  In the automatic cooking mode, when heating control is performed by linking the external temperature detection means 30 and the induction heating cooker 100, the heated container 10 to which the external temperature detection means 30 is attached is disposed on the heating port 6 to be heated. Otherwise, the temperature of the heated container 10 to be heated cannot be detected, and incorrect heating control will be performed. Then, the main body side control part 22 which concerns on this Embodiment determines whether the external temperature detection means 30 is arrange | positioned on the heating port 6 of heating object before performing automatic cooking mode. I do.

FIG. 6 is an example of temperature detection transition according to the embodiment of the present invention.
6A is a graph showing an example of the transition of the detected temperature of the infrared temperature sensor 25, and FIG. 6B is a graph showing an example of the transition of the detected temperature of the external temperature detecting means 30. 6 (c) is a graph showing an example of the transition of the power supplied to the heating coil 14.
Here, when the external temperature detecting means 30 is attached to the heated container 10 on the heating port 6 to be heated, that is, the external temperature detecting means 30 is arranged on the heating port 6 to be heated. In this case, the temperature detected by the infrared temperature sensor 25 and the temperature detected by the external temperature detection means 30 increase with the passage of time as shown in FIGS. 6 (a) and 6 (b). When the temperature difference after the preset time is within the preset allowable range, it is determined that the external temperature detecting means 30 is disposed on the heating port 6 to be heated.

FIG. 7 is a threshold table for sensor determination processing according to the embodiment of the present invention.
FIG. 7 is a table showing an example of a determination result based on the temperature difference ΔT_ir or ΔT_pro and an operation according to the determination result.
As shown in FIG. 7, when the temperature difference ΔT_ir_1 is greater than 10 ° C. and less than or equal to 25 ° C., or when the temperature difference ΔT_pro_1 is greater than 15 ° C. and less than or equal to 30 ° C., that is, the temperature after the elapse of a preset time (Time_1) When the change is within the allowable range, it is determined that the external temperature detection means 30 is disposed on the heated heating port 6.

  On the other hand, if the temperature difference ΔT_ir_1 is 10 ° C. or less, or if the temperature difference ΔT_pro_1 is 15 ° C. or less, that is, if the temperature change after the elapse of a preset time (Time_1) is smaller than the allowable range, The heated container 10 is not disposed on the opening 6 or the external temperature detecting means 30 is not attached to the heated container 10 on the heated opening 6 to be heated, and the heated opening 6 to be heated It is determined that the external temperature detection means 30 is not disposed on the top.

In addition, when the temperature difference ΔT_ir_1 is greater than 25 ° C., or when the temperature difference ΔT_pro_1 is greater than 30 ° C., that is, when the temperature change after a preset time (Time_1) elapses is larger than the allowable range, Although the external temperature detection means 30 is attached to the heated container 10 above the opening 6 and the external temperature detection means 30 is disposed on the heating opening 6 to be heated, the heated container 10 is heated. There is no object and it is determined that it is in an baked state.
For this reason, when the temperature difference after the preset time is not within the preset allowable range, the heating is stopped and the determination result is notified.

FIG. 8 is a flowchart showing a flow of sensor determination processing according to the embodiment of the present invention.
This process is started by the main body side control unit 22 when the power source of the induction heating cooker 100 is turned on.
In this process, it is first determined whether or not the automatic cooking mode has been selected (S1). The automatic cooking mode is selected by pressing the automatic cooking menu key 3b of the operation / display unit 3 corresponding to the heating port 6 to be heated.
When the automatic cooking mode is not selected (S1: No), this process is terminated, and heating control according to the operation of the operation / display unit 3 is performed.

  On the other hand, when the automatic cooking mode is selected (S1: Yes), a state confirmation signal is transmitted from the main body side communication unit 21 to the external temperature detection means 30 (S2). When the power supply of the external temperature detection unit 30 is on, the sensor side communication unit 301 receives a state confirmation signal, and the sensor side control unit 302 is turned on via the sensor side communication unit 301. Is returned to the main body side communication unit 21.

And it is judged by the main body side control part 22 whether the signal which shows that the power supply is an ON state was returned from the external temperature detection means 30 (S3).
When there is no response from the external temperature detection means 30 indicating that the power is on (S3: No), the notification means 28 of the main body 1 is used to indicate that the power supply of the external temperature detection means 30 is off. Notification is made by sound or light (S4).

  After that, when a status confirmation signal is transmitted and no reply is received even after a preset time has elapsed (S5: Yes), it is determined that the external temperature detection means 30 cannot be used for heating control (S6). The heating control is performed using temperature detection means other than the external temperature detection means 30 suitable for the selected automatic cooking menu. That is, the automatic cooking mode is started, and heating control is performed using either one or both of the infrared temperature sensor 25 and the contact temperature sensor 26 arranged below the top plate 2 (S13).

  On the other hand, when a signal indicating that the power is on is returned from the external temperature detection unit 30 (S3: Yes), the detection detected by the external temperature detection unit 30 as the initial temperature from the external temperature detection unit 30 The temperature T_pro_0 is acquired (S7), and heating of the heating port 6 to be heated by the heating coil 14 is started with a preset power amount (W_0) (S8). Thereafter, it is determined whether or not a preset time has elapsed (S9). If the preset time has not elapsed (S9: No), heating with a preset electric energy (W_0) is performed. Will continue. On the other hand, when the preset time has elapsed (S9: Yes), the detected temperature T_pro_1 detected by the external temperature detection means 30 after the preset time has elapsed is acquired (S10).

  The detected temperature T_pro_0 corresponds to the “initial temperature” of the present invention, and the detected temperature T_pro_1 corresponds to the “elapsed temperature” of the present invention.

Then, it is determined whether or not the difference ΔT_pro between the detected temperature T_pro_1 and the detected temperature T_pro_0 is within a preset range (S11). The preset range is an allowable range shown in FIG. 7, for example.
When the difference ΔT_pro between the detected temperature T_pro_1 and the detected temperature T_pro_0 is within a preset range (S11: Yes), it is determined that the external temperature detecting means 30 can be used for heating control (S12). And automatic cooking mode is started and heating control is performed using the external temperature detection means 30 (S13). In the heating control using the external temperature detection unit 30, the sensor side control unit 302 of the external temperature detection unit 30 transmits the temperature information detected by the temperature sensor element 36 of the sensor unit 35, for example, at a cycle of 1 second. It transmits to the main body side communication unit 21 via the unit 301.

  The main body side communication unit 21 of the main body 1 receives temperature information from the external temperature detection means 30, and the main body side control unit 22 acquires the temperature information received by the main body side communication unit 21. The main body side control unit 22 controls the high-frequency inverter 24 toward a preset target temperature, and repeats the stop and start of heating or changes the input power so that the temperature information becomes the target temperature.

  On the other hand, if the difference ΔT_pro between the detected temperature T_pro_1 and the detected temperature T_pro_0 is not within a preset range (S11: No), it is determined that the external temperature detecting means 30 cannot be used for heating control (S11: No). S6). And automatic cooking mode is started and heating control is performed using either one or both of the infrared temperature sensor 25 and the contact-type temperature sensor 26 which are arrange | positioned under the top plate 2 (S13).

  As described above, in the present embodiment, it is determined whether or not the external temperature detection means 30 can be used for heating control, and if it can be used, the external temperature detection means 30 causes the inside of the container 10 to be heated. By detecting the temperature of the stored food, it is possible to improve the detection accuracy and the followability of detection. As a result, highly accurate temperature control in the automatic cooking mode is possible, cooking failure due to excessive temperature rise can be suppressed, and cooking suitable for foods can be performed without the user performing a heating power changing operation. Therefore, it is possible to improve convenience, to suppress the temperature rise due to spilling or emptying, and to suppress unnecessary heating.

  Further, when the external temperature detection means 30 is not turned on, and when the external temperature detection means 30 is turned on but the food temperature is not detected, the external temperature suitable for the selected automatic cooking mode is selected. By using the temperature detected by the temperature detection means other than the temperature detection means 30, cooking can be continued without causing the user to perform complicated work.

FIG. 9 shows an automatic cooking menu and a reference sensor table according to the embodiment of the present invention.
Here, the operation when it is determined that the external temperature detection means 30 cannot be used for the heating control because the power supply of the external temperature detection means 30 described in the flow S4 is in an off state. This will be specifically described with reference to FIG.
For example, among the automatic cooking menus, any of the “boiled” menu, “boiled noodles” menu, and “boiled water” menu is selected, and it is determined that the external temperature detection means 30 cannot be used for heating control. In the case of a failure, the heating control is performed with reference to the contact-type temperature sensor 26 arranged below the top plate 2.

  In this case, since the control method changes depending on the installation state of the container 10 to be heated and the amount of ingredients to be added, the use of the external temperature detection means 30 for the user further improves the cooking property, and the contact temperature sensor 26 is used. It may be notified that the temperature is detected. Note that a control method performed when the temperature detection means to be referred to is changed will be described later and compared with a control method using the external temperature detection means 30.

  When the “baked goods” menu is selected in the automatic cooking menu, cooking is performed using a frying pan as the heated container 10, and the frequency of pot-shaking and mixing of ingredients is increased. It may be difficult. In addition, although the set temperature is a high temperature of 140 ° C. or higher, since the infrared temperature sensor 25 can sufficiently detect the temperature, the control without using the external temperature detecting means 30 is fundamental. Therefore, when the “baked goods” menu is selected, it is not necessary to determine whether or not the external temperature detection means 30 can be used for heating control. Although the infrared temperature sensor 25 is mainly referred to in FIG. 9, the contact temperature sensor 26 is also referred to for determining the placement state of the heated container 10, determining the emissivity, and correcting the infrared temperature sensor 25. May be. Thus, when the “baked goods” menu is selected, the use of temperature detection means other than the external temperature detection means 30 can avoid difficulty in cooking and improve usability.

  In the automatic cooking menu, when the “fried food” menu is selected and it is determined that the external temperature detection means 30 cannot be used for heating control, the infrared temperature sensor 25 and the contact temperature sensor 26 are used in combination. To control the temperature. Although the set temperature of the deep-fried food becomes a high temperature of 140 ° C. or higher, the infrared temperature sensor 25 can sufficiently detect the temperature. Further, the contact-type temperature sensor 26 can accurately detect the temperature of the bottom of the heated container 10 as long as the heated container 10 is placed in contact with the top plate 2. Such a temperature detection method will be described in detail later, but the viscosity coefficient of oil changes depending on the temperature, and when the viscosity is low and the temperature is low, the temperature gradient tends to occur.

  Therefore, if the external temperature detecting means 30 is used, it is less susceptible to the oil viscosity change than the method of detecting the temperature of the bottom of the heated container 10, and it is possible to apply a high heating power from the beginning, and preheating. The time can be advanced, and it is possible to accurately grasp the temperature return after the food is added. For this reason, it is possible to maintain a temperature suitable for food in fried food cooking for a long time, and to cope with changes in temperature when the container 10 is heated, a small amount of oil is cooked, and a large amount of food is added. Disappear.

  However, since the temperature of the bottom portion of the heated container 10 can be accurately captured by using the infrared temperature sensor 25 and the contact temperature sensor 26 as described above, the external temperature detection means 30 is not necessarily used. In addition, it is possible to reduce the burden on the user who feels troublesome to clean by putting it in oil.

  Further, in the automatic cooking menu, when the “temperature setting” menu is selected and it is determined that the external temperature detection means 30 cannot be used for heating control, the contact-type temperature sensor 26 and Which of the infrared temperature sensors 25 is used is determined and switched.

  In addition, heating is performed with a constant heating power for a preset time (for example, about 60 seconds) from the start of heating, and the installation state and emissivity of the container to be heated 10 are determined based on the temperature increase detected by the contact temperature sensor 26 at that time. May be used for determining the correction ratio of the infrared temperature sensor 25. For example, if the set temperature is 140 ° C. or less, heating control is performed using the contact temperature sensor 26, and if the set temperature is higher than 140 ° C., the infrared temperature sensor 25 is mainly used to perform heating control.

  Here, in the automatic cooking menu, any of the above-mentioned “boiled” menu, “boiled noodles” menu, and “boiled water” menu is selected, and heating control is performed using the external temperature detection means 30; A detailed description will be given by comparing the case where the temperature control means 30 is not used and the heating control is performed using the contact temperature sensor 26 instead.

  First, in the automatic cooking menu, when the “boiled” menu is selected and the external temperature detection means 30 is used, it is possible to perform heating using a temperature sequence that matches the food in the “boiled” mode. For example, there are many dishes that stew, such as oden, pumpkin simmered, curry, pork simmered, etc., but when using the external temperature detection means 30, the optimum temperature for the ingredients used for each cooking It can be done continuously. For example, if you want to cook vegetables such as pumpkin boiled foods, curry potatoes and onions so that they do not boil, maintain a preset time at a temperature of 50 ° C to 70 ° C, preferably around 60 ° C at the beginning of heating. By doing so, it is known that even if it is boiled for a long time, it does not easily boil.

  Here, vegetable ingredients such as vegetables and fruits tend to soften and soften when heated. Therefore, when it is desired to soften the ingredients, it is necessary to heat (boil) the ingredients for a long time. And although the one where the temperature to heat is high can make a foodstuff soft quickly, there is a possibility that it may boil. Therefore, when foods such as vegetables are boiled in a temperature range of 50 ° C. to 70 ° C. in the initial stage of heating, a hardening phenomenon occurs due to the action of a substance called pectin contained in cell walls and cell intervals of vegetables, and then heating at a high temperature. Even if it becomes hard to become soft even if it raises to the preset temperature after that and simmers for a long time after that, it will become difficult to boil. And the temperature of the heating initial stage where the effect by the said hardening phenomenon becomes most remarkable is 60 degreeC.

  Further, in Japanese-style soups such as kelp, fish stock and soy sauce used in stewed oden and vegetables, umami components such as sodium glutamate and glutamic acid can be extracted at higher temperatures. However, the higher the temperature, the more the volatile scent flies away, and when it is boiled with kelp, ingredients that are not desirable for cooking such as stickiness and odor may be eluted. It is known to take out before boiling. In cooking to take such soup stock, it is possible to notify before boiling, or to stew while maintaining around 80-90 ° C. so as not to boil.

  On the other hand, stewed meat such as stewed pork and stewed beef meat tend to be soft and mellow when simmered at high temperature for a long time. In this case, the collagen contained in the meat protein is involved, shrinks from 65 ° C. and becomes hard, and begins to soften at 75 to 85 ° C. For this reason, when you want to finish meat softly, it is ideal to boil at a temperature higher than 85 ° C, and in the case of cooking at normal pressure, if the temperature is raised to 100 ° C or higher, the juice will evaporate, Since it may burn, it is necessary to boil at 85-95 degreeC.

  As described above, it is possible to maintain the temperature and heating time suitable for the food and the cooking menu, and it is possible to perform heating control that is not affected by the installation state of the heated container 10 and the amount of food.

  The selection of the cooking method suitable for the ingredients and the cooking menu may be made by selecting / displaying “dashi”, “vegetables”, “meat”, etc. on the operation / display unit 3 when the automatic cooking menu is selected. A frequently used cooking menu such as “oden”, “curry”, and “pig simmered pork” may be displayed. In addition, in an environment where the home LAN and the induction heating cooker 100 are connected, it is possible to link with a mobile terminal or the like that is linked to the home LAN. The operation method and display method used in the selection method described above are merely examples, and the present invention is not limited to this.

  On the other hand, when the external temperature detection means 30 is not used, heating control is performed using the contact temperature sensor 26 as described above. When the contact-type temperature sensor 26 is used, the temperature at the bottom of the container 10 to be heated is detected by the temperature transmitted to the top plate 2. Therefore, if the container 10 to be heated is deformed or floats, external temperature detection means is used. The temperature cannot be detected with the same detection accuracy as 30. Therefore, a process for confirming whether the installation state of the container 10 to be heated is at a level at which heating control is possible is provided. When it is determined that heating control is possible, the heating control suitable for the above-described food is performed, and the heating control is performed. When it is determined that it is not possible, heating is performed at the initial target temperature and heating time.

  Specifically, as a means for determining whether the heating control is possible, the temperature rise when a preset power is input for a preset time (for example, the temperature rise when a 1500 W is supplied for 30 seconds is 20). The primary determination is made based on whether or not (˜50 ° C.) is within a preset range. Then, as a next step, heating control is performed so that the temperature of the contact-type temperature sensor 26 becomes constant at 55 ° C. before the cooking-curing temperature 60 ° C. that prevents vegetables from collapsing.

  Note that the temperature detection time of the contact-type temperature sensor 26 is delayed if the mounted state of the heated container 10 is deformed or floats due to the stability of output (hunting width and cycle time) with respect to the 55 ° C. setting. However, when the temperature detected by the contact-type temperature sensor 26 reaches 55 ° C., the actual temperature of the heated container 10 greatly exceeds 55 ° C., so that the sensor output overshoot increases.

  In this way, when the temperature can be accurately detected by the contact temperature sensor 26, the heating control is performed, and when the heating control is difficult, the heating control is performed under the initial setting conditions.

  Next, the “noodle boiled” menu will be described. The “noodle boiled” menu consists of a noodle boiled preheating step and a noodle boiled step, and the noodle boiled preheated step boils water for boiling the noodles. When it is detected that at least two of the plurality of temperature sensor elements 36 of the sensor unit 35 are preset temperatures (temperatures in water), the heating power is increased to a preset first temperature higher than the preset temperature. A process of heating at A (for example, 3 kW), and the noodle boiling process is 92 ° C. or higher which is lower than the first temperature at a thermal power B (for example, 2 kW) lower than the thermal power A after the noodles are charged. In this step, the noodles are boiled in the range of ℃ or lower.

  In the automatic cooking menu, when the “noodle boiled” menu is selected and the external temperature detecting means 30 is used, an accurate temperature can be detected regardless of the amount of water, so that the boiling temperature is reached (100 ° C.) in the noodle boiled preheating step. Notification will be given later. After that, noodles such as udon and somen are introduced into the noodle boiling process, but the filmed material such as starch contained in the noodles is formed on the hot water surface, and the water vapor evaporated by boiling the hot water forms the film. The phenomenon of pushing up and spilling occurs.

  In order to suppress this spill, the boiling temperature is not raised and continued to boil, and the noodles are boiled firmly, causing convection and transferring heat to the noodles with bubbles generated from the bottom of the container 10 to be heated. Things are necessary. In order to control such heating, when the noodle boil process is started, the noodle boil temperature is changed in a range of 92 ° C. or more and 100 ° C. or less, and the noodle boil is performed. At this time, temperature detection in the height direction of the container 10 to be heated is performed, and heating control is performed so that the temperature difference in the height direction does not deviate more than a preset value. Also, the boiled time of noodles changes depending on the thickness and preference, so input the specified time from the user at the initial stage, make noodle throwing judgment (temperature drop), and then notify when the specified time is over Things are also possible.

  On the other hand, when the external temperature detection means 30 is not used, temperature control is performed using the contact-type temperature sensor 26 as in the above-described “boiled” function. When the contact type temperature sensor 26 is used, it is determined whether the heating control is possible. When it is determined that the heating control is possible, the heating control using the contact type temperature sensor 26 is performed. At that time, the temperature range of the noodle boil in the noodle boiling step was 92 ° C. or more and 100 ° C. or less in the external temperature detection means 30 in consideration of the effect of delaying the heat conduction of the top plate 2. 26, the temperature is in the range of 92 ° C. or higher and 96 ° C. or lower. By doing so, the boiling time can be prolonged due to overshoot, and the occurrence of spilling can be prevented.

  On the other hand, if it is determined that the heating control is not possible, the input power is also sequentially reduced each time the temperature detected by the contact temperature sensor 26 is increased, and the power is turned on / off every time period when the temperature is in the vicinity of 90 ° C. To heat. In addition, regarding the boiled time of noodles, the user may set the boiled time from the timer setting key 3d of the operation / display unit 3.

  Next, in the automatic cooking menu, when the “boiling water” menu is selected and the external temperature detecting means 30 is used, it is possible to turn on electric power close to the maximum heating power, and immediately after boiling (100 ° C.). It is possible to notify, and power consumption can be suppressed by turning off the power immediately after boiling, or by reducing the power and maintaining it at a preset temperature. In the “boiling water” menu, water (hot water) is heated with a thermal power C (for example, 3 kW) until a preset temperature (100 ° C.) is reached, and a thermal power D lower than the thermal power C when the preset temperature is exceeded. Water (hot water) is heated at (for example, 750 W).

On the other hand, when the external temperature detecting means 30 is not used, it is determined whether or not the heating control is possible as in the above-mentioned “noodle boiled” menu. Here, the process in the “boiled water” menu corresponds to the process before the noodle boil process in the “noodle boil” mode.
And if it judges that heating control is possible, it will heat using the contact-type temperature sensor 26, but the influence which the heat conduction of the top plate 2 was overdue was considered, and it was 100 degreeC in the external temperature detection means 30. However, the contact-type temperature sensor 26 notifies when the temperature reaches about 95 ° C., or turns off or reduces the power.

  On the other hand, if it is determined that heating control is not possible, the input power is also decreased sequentially each time the temperature detected by the contact-type temperature sensor 26 is increased, and the amount of water and the floating state of the heated container 10 are determined from the inclination of the temperature rise. When it is determined that the estimated temperature has reached boiling, a notification is made, and the power that is initially set by the amount of water determined from the temperature rise is also input as the heat retaining power.

Next, in the automatic cooking menu, the “fried food” menu is selected, and a detailed description will be given regarding a control method when the external temperature detection means 30 is not used.
In the “fried food” menu, in order to perform cooking using oil, control is performed to maintain a constant temperature at a set temperature of 140 to 200 ° C. Therefore, as described above, the infrared rays radiated from the bottom of the heated container 10 pass through the top plate 2, and the infrared temperature sensor 25 can detect the temperature. For this reason, since the temperature of the oil itself is measured when the external temperature detection means 30 is used, preheating is performed with high thermal power and the return after the introduction of the food is quick as described above. Even if the means 30 is not used, it is possible to perform temperature control using the temperature detected by the infrared temperature sensor 25.

As a temperature detection method using the infrared temperature sensor 25, grasping the ratio of the amount of infrared energy due to the difference in emissivity at the bottom of the container 10 to be heated, that is, the infrared rays that are emitted when the top plate 2 is heated, and illumination It is necessary to separate from ambient light such as sunlight.
First, as a method for detecting the emissivity, although not shown, a light projecting unit that emits light toward the bottom of the heated container 10 and a light receiving unit that receives the reflected light reflected by the bottom of the heated container 10. The emissivity level is judged by providing means. Alternatively, the determination can also be made by comparing the temperature rise degrees of the infrared temperature sensor 25 and the contact-type temperature sensor 26 when the preset power is applied at the preset time.

  The infrared energy radiated from the top plate 2 is separated by using the output of the contact temperature sensor 26, and disturbance light due to illumination, sunlight or the like is shielded from the top plate 2 so as not to enter the infrared temperature sensor 25 as much as possible. It is controlled by paint, infrared temperature sensor casing, etc., and the control is performed by offsetting the output value at the beginning of heating.

  An example of a specific control method using the above judgment is as follows. Heating is performed at 1500 W for 60 seconds, and the temperature rising from the initial temperature of the infrared temperature sensor 25 and the contact temperature sensor 26 for 60 seconds is measured. Depending on the temperature, the state of the heated container 10 is placed (if the rising temperature of the contact temperature sensor 26 is small, it is determined that the gap distance from the top plate 2 is large), and the emissivity of the bottom of the heated container 10 ( Simultaneously with the determination of the size of the gap distance with the top plate 2 described above, the gap distance is large, and the temperature detected by the contact temperature sensor 26 and the temperature rise detected by the infrared temperature sensor 25 are set in advance. If it is greater than the value, it is determined that the emissivity is high).

Thus, when the mounting state of the heated container 10 and the emissivity of the bottom of the heated container 10 are determined, the correction coefficient 見 corresponding to the conditions is multiplied by the detected temperature of the infrared temperature sensor 25, and the contact temperature A temperature estimated value (T _obj ) of the bottom of the heated container 10 is obtained using a value obtained by multiplying the detected temperature of the sensor 26 by the correction coefficient と し て as the temperature of the bottom of the heated container 10.
When the detected temperature of the infrared temperature sensor 25 is T _ir , the detected temperature of the contact temperature sensor 26 is T _th , the correction coefficient Α is α, and the correction coefficient Β is β, the following relational expression is derived.
T _obj = T _ir × α−T _th × β (1)
With reference to the temperature calculation formula of the heated container 10 obtained by the above formula (1), heating control is performed so that the temperature estimated value T _obj matches the set temperature.

  In the above-mentioned “baked goods” menu, it is described that the heating control without using the external temperature detecting means 30 is performed, but the method is the same as the heating control method when the external temperature detecting means 30 is not used in the “fried food” menu. It is.

Next, a detailed description will be given regarding a control method in the case where the “temperature setting” menu that allows the user to set the temperature that the user wants to set individually is selected and the external temperature detection means 30 is used.
When the “temperature setting” menu is selected and it is determined that the external temperature detection unit 30 can be used for heating control, the set temperature input by the user through the operation / display unit 3 and the external temperature detection unit 30 Thermal power control is performed so that the detected temperature becomes the same. Then, when the set temperature and the detected temperature of the external temperature detecting means 30 are the same (when the detected temperature of the external temperature detecting means 30 reaches the set temperature), the notification means 28 of the main body 1 notifies.

  Control when the external temperature detection means 30 is not used is based on whether the temperature is higher than 140 ° C., the heating control described in the “boiled water” menu, and the heating described in the “fried food” menu. The control unit provided in the device determines whether to control. The basis for the switching target temperature of 140 ° C. is defined because the amount of transmission in principle is small when the infrared light transmitted through the top plate 2 is lower than 140 ° C. You may change suitably according to the material of the plate 2. FIG.

  The aforementioned control method is an example, and is not limited to this control method. While maintaining the interpolation relationship using the detected temperatures of the external temperature detection means 30, the contact temperature sensor 26, and the infrared temperature sensor 25 as appropriate, Heating control is performed.

As described above, the induction heating cooker 100 according to the present embodiment includes the infrared temperature sensor 25, the contact temperature sensor 26, and the external temperature detection means 30, and the main body side control unit 22 includes the operation / display unit. The temperature detection means to be used is determined according to the automatic cooking menu selected in 3, and the heating coil 14 is controlled based on the temperature detected by the determined temperature detection means and the control sequence of the selected automatic cooking menu. Therefore, it is easy to use and the temperature can be accurately detected according to the situation, so that optimum heating control can be performed.
Moreover, since the external temperature detection means 30 is the structure attached to the to-be-heated container 10, since it can use other than the specific to-be-heated container 10, and can respond to the to-be-heated container 10 of various shapes, versatility high.
In addition, since the temperature detecting means to be used is automatically determined according to the selected automatic cooking menu, the user does not have to select himself / herself and the troublesome work for the user can be reduced.

  In addition, although the induction heating cooking appliance 100 which concerns on this Embodiment was set as the structure provided with the infrared temperature sensor 25, the contact-type temperature sensor 26, and the external temperature detection means 30 as a temperature detection means, it is not limited to it, What is necessary is just to provide at least one among the external temperature detection means 30, the infrared temperature sensor 25, and the contact-type temperature sensor 26. FIG. Moreover, you may provide temperature detection means other than the said three temperature detection means.
