(Embodiment 1)
FIG. 1 illustrates an induction heating cooker as a heating cooker according to Embodiment 1 of the present invention.

  As shown in the figure, the heating cooker according to the present embodiment is a heating means composed of a heated object 102 such as a pan in which the object 101 is to be cooked, and an annular heating coil for induction heating the lower part of the heated object 102. 103, a high frequency power supply means 104 for performing induction heating using the heating means 103, a plurality of (first and second) temperature measuring means 105, 106 for measuring the temperature of the lower part of the object to be heated 102, A heating amount relative rank storage means 107 storing the heating amount relative ranks of the plurality of temperature measuring means 105 and 106 determined by the shape of the heating means 103, and a heating amount stored in the heating amount relative rank storage means 107. Bumping possibility determination means 108 that determines the possibility of bumping occurrence by examining whether or not the temperature distribution is different from the relative order, and a control means that performs heating control according to the possibility of bumping And a 09.

  Note that the first temperature measuring means 105 is disposed below the object to be heated 102 facing the heating means 103, and the second temperature measuring means 106 is located at the center of the heating means 103 (on the heating means 103). It is arrange | positioned in the lower part of the to-be-heated object 102 facing no winding.

  Here, the object to be heated 102 is a pan, the first temperature measuring means 105, the second temperature measuring means 106 is a temperature sensor such as a thermistor, the high frequency power supply means 104 is an induction heating inverter, and the heating amount relative rank. The above configuration can be easily realized by using a microcomputer for the storage unit 107, the possibility of bumping determination unit 108, and the control unit 109.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the user puts the object to be cooked 101 into the object to be heated 102 and instructs the warming of the object to be cooked 101, the control means 109 operates the high frequency power supply means 104 to supply the heating means 103 with high frequency power. When the heating means 103 generates a high-frequency magnetic field, induction heating of the object to be heated 102, and the bumping possibility determination means 108 determines that bumping may occur, the control means 109 performs heating control (for example, heating stop). If there is no determination, heating is continued.

  Here, the heating amount relative rank storage means 107 stores the heating amount relative rank from the magnetic flux density distribution used for heating generated from the winding shape of the heating means 103 under the following conditions.

First temperature measuring means 105> second temperature measuring means 106
Next, the principle that the bumping phenomenon occurs when the heating amount relative rank is out of the condition will be described with reference to FIGS.

  In FIG. 2A, the object to be heated 102 contains an object to be cooked 101, an object to be heated precipitate layer 201, and bubbles 202. For example, in the case of a water-soluble cooked food 101 composed of large-grained components such as miso, after being cooked in a heated object 102 such as a pan and left for a while, In many cases, the ingredients of the object to be cooked 101 are deposited in the lower center portion to form a layer. Here, this is referred to as a heated object precipitation layer 201. In this case, the maximum point of the heating distribution (position of the first temperature measuring means 105) determined from the shape of the heating means 103 and the vicinity of the center where the heated object precipitation layer 201 is easily formed, and a certain amount of magnetic flux is present. If there are two points that are generated and the amount of heating is secured (the position of the second temperature measuring means 106), the possibility of bumping can be determined.

  When heating is started in a state where the object to be cooked 101 is precipitated to form a layer, the heated object precipitation layer 201 becomes a thermally closed system, so the temperature in the heated object precipitation layer 201 Tends to rise. In this state, when the object to be cooked 101 and the object to be heated 102 are heated by the high-frequency power through the heating means 103, the object to be heated is as shown in (1) of FIG. Bubbles 202 due to boiling begin to be generated in the portion where the heating distribution in the precipitation layer 201 is the highest, and the generated bubbles become large without being able to go out of the heating object precipitation layer 201 in the middle stage before the bumping phenomenon occurs. As shown in (2) of 2 (b), the state becomes empty. At this time, the difference between the temperature change in the normal heating state as shown in FIG. 3A and the temperature change before the bumping phenomenon as shown in FIG. In the latter stage before the bumping phenomenon shown in (3) of FIG. 2 (b), the bubble 202 grows large enough to have a force to break the heated object precipitation layer 201. To do. And when the to-be-heated material precipitation layer 201 is broken and the bubble 202 jumps out, it will express as a big bumping phenomenon.

  In order to prevent a bumping phenomenon that occurs when the heating amount relative rank condition is not satisfied, the bumping possibility determination unit 108 performs bumping possibility determination by an operation as shown in FIG.

  During heating, the temperature obtained from the first temperature measuring means 105 and the second temperature measuring means 106 is acquired (S401), and the heating amount relative rank stored in the heating amount relative rank storage means 107 is referred to (S402). It is monitored whether or not the above conditions stored in the heating amount relative rank storage means 107 are not met (S403). If the conditions are not met for a predetermined time (for example, 10 seconds) (S404), the control means 109 is notified. The control means 109 performs heating control (for example, heating stop) (S405), and if not deviated from the conditions, the above operation is continued until the heating is completed (S406).

  As described above, in the present embodiment, when the component of the object to be cooked 101 is in the state of forming the object to be heated precipitation layer 201, it is generated by boiling at the portion where the object to be cooked 101 is precipitated. Since the air bubbles 202 are accumulated without being able to escape from the heated object precipitation layer 201, the cooking object precipitation layer 201 becomes empty. Utilizing this increase in temperature, the heating amount relative rank is stored in advance in the heating amount relative rank storage means 107, and the temperature measurement means 105, 106 stores the heating amount relative rank stored in the heating amount relative rank storage means 107. It is possible to determine the possibility of bumping by examining whether or not the temperature distribution is different from the above, and to perform heating control according to the possibility of bumping.

  In the present embodiment, the two temperature measuring means 105 and 106 are used for the determination. However, there is a place where the cooked material precipitation layer 201 can be formed like the cooked food 101 having a high viscosity or the cooked food 101 having a large weight. Needless to say, when the temperature is not limited to the center lower part of the article to be heated 102, the accuracy of the bumping possibility determination can be improved by using three or more temperature measuring means.

(Embodiment 2)
FIG. 5 shows a cooking device according to Embodiment 2 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in the figure, in the heating cooker according to the present embodiment, the third temperature measuring means 501 is disposed below the object to be heated 101 facing the central portion of the heating means 103 (without the winding of the heating means 103). It is a thing. Other configurations are the same as those in the first embodiment.

  Note that this configuration can be easily realized by using a temperature sensor such as a thermistor for the third temperature measuring means 501.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Although the basic operation is the same as that of the first embodiment, the third temperature measuring unit 501 is located at a position where there is almost no magnetic field generated by the winding portion of the heating unit 103 and the object to be heated 102 is not directly heated. Is arranged as a temperature measuring means. Since the object to be heated 102 such as a pan is not directly heated at the position of the third temperature measuring means 501, the heating amount relative rank is the original order in the state where the heated object precipitation layer 201 is formed. When the heating proceeds in a different state, the heated object precipitation layer 201 is thermally closed. For this reason, when the third temperature measuring means 501 exceeds the boiling point while the heating amount relative order is different, the bubble 202 grows greatly, and the possibility of the bumping phenomenon becomes very high.

  Therefore, in the bumping possibility determination, as shown in FIG. 6, a state (S403) in which the heating amount relative ranks are different continues for a predetermined time (S404), and a specific temperature measuring unit (third temperature measuring unit 501). Is over the boiling point (here, 100 ° C.) (S601), and if it exceeds, heating control is executed as there is a possibility of bumping (S405).

  As described above, in the present embodiment, when the temperature of the portion having the lowest temperature distribution rises to the vicinity of the boiling point of water in a state where the food to be cooked 101 forms the food to be cooked sediment layer 201, the bubbles 202 In the situation where it can be determined that the cooked food precipitation layer 201 is formed with a temperature distribution different from the heating amount relative rank stored in the heating amount relative rank storage means 107. Thus, when the lowest portion of the temperature distribution approaches the boiling point, the bumping possibility determination means 108 determines that there is a possibility of bumping, so that reliable bumping detection can be performed.

(Embodiment 3)
FIG. 7 shows a cooking device according to Embodiment 3 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in the figure, the heating cooker in the present embodiment includes a temperature difference absolute value determination means 701 for confirming the absolute value of the temperature difference between the plurality of temperature measurement means 105 and 106, and a bump boiling possibility determination means 108. To provide judgment conditions. In addition, a timer means 702 is provided so that the electric power given to the object to be heated 102 can be changed periodically. Also, the cooking mode selection means 703 is provided, and the heating control by the bumping possibility determination means 108 is used only when the cooking mode for warming is selected. In addition, a heating restriction control cancellation selection unit 704 is provided, and it is possible to cancel the determination of the possibility of bumping by the bumping possibility determination unit 108. Furthermore, a heating control execution display unit 705 for notifying that the heating limit has been performed when the heating amount limitation by the bumping possibility determination unit 108 is performed is provided. Other configurations are the same as those in the first embodiment.

  It should be noted that a temperature difference absolute value determination means 701 and a timer means 702 use a microcomputer, a cooking mode selection means 703, a heating restriction control release selection means 704 use a switch and a microcomputer, and a heating control execution display means 705 uses an LED. Thus, the above configuration can be easily realized.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Here, the temperature difference absolute value determination means 701 utilizes the fact that the absolute value of the temperature difference between the temperature measuring means 105 and 106 is large for the object to be heated (pot) 102 having low thermal conductivity and easily causing bumping, The temperature difference absolute value between the plurality of temperature measuring means 105 and 106 at the initial stage of heating is determined, and it is determined whether or not the temperature difference absolute value is a predetermined value (for example, 30 [deg]) or more. If the heated object 102 is prone to bumping, it is possible to reliably detect bumping by performing a bumping possibility determination by the bumping possibility determination means 108. it can.

  In addition, periodic processing is performed using the timer unit 702, and the high-frequency power supply unit 104 periodically (for example, once every 5 seconds) from the high-frequency power supply unit 104 in the initial stage of heating is 1.5 times the set heating power. ) Is supplied to the object to be heated 102 for a certain time (for example, 1 second), thereby giving a fluctuation in the object to be heated precipitation layer 201 and increasing the possibility that the bubble 202 breaks through the object to be heated precipitation layer 201. It is possible to prevent the occurrence of bumping.

  In addition, when the user starts cooking, when cooking fried food, fried food, etc., cooking is performed using the cooking mode selection means 703 so that the heating restriction is not unintentionally performed. By allowing the user to select the mode, the bumping possibility determination heating control can be performed only when necessary.

  In addition, when the user does not want to automatically adjust the heating power, the heating control canceling selection unit 704 can select the heating control using the bumping possibility determination unit 108 not to operate. Thereby, although automatic heating control is normally performed so that bumping does not occur, a user who hates misjudgment can also intentionally prohibit it.

  Further, when the bumping possibility determination means 108 performs the bumping possibility determination and performs the heating amount restriction, the heating control execution display means 705 is used to notify the user of the fact that the restriction has been made, so that the bumping boiling possibility is determined. Encourage the execution of heating while stirring so as not to occur.

  As described above, in the present embodiment, the object to be heated (pot) 102 having low thermal conductivity and prone to bumping utilizes the fact that the absolute value of the temperature difference between the temperature measuring means 105 and 106 is large. The temperature difference absolute value determination means 701 can determine the possibility of bumping more accurately in consideration of the characteristics of the heated object 102 such as a pan. In addition, the timer means 702 periodically applies high power to the object to be heated 102 such as a pan and generates strong bubbles from time to time, thereby fluctuating the internal state in which the bubbles 202 are accumulated in the cooking object precipitation layer 201. By giving the bubbles 202 confined in the precipitation layer little by little, it is possible to prevent the concentration of energy that causes bumping and to reduce the possibility of bumping. In addition, the heating control using the bumping possibility determination unit 108 is operated only when the user selects the cooking mode in which the cooking mode is selected by the cooking mode selection unit 703, so that the heating control is performed only when necessary. be able to. In addition, the user who hates erroneous determination can be intentionally prohibited by the heating restriction control release selection means 704. Further, when the bumping possibility determining means 108 limits the heating amount by heating control, it is possible to prompt the execution of heating while stirring so that bumping does not occur by notifying the fact that the electric power necessary for heating is limited. .

  In addition, the means described in the first to third embodiments are used for hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electric / information device including an I / O, a computer, a server, You may implement in the form of the program made to cooperate. In the case of a program, the program can be distributed / updated and installed easily by recording it on a recording medium such as magnetic media or optical media, or by distributing it through a communication line such as the Internet.

  In addition, in said each Embodiment 1-3, although the induction heating cooking appliance was illustrated as a heating cooking appliance, it is not restricted to this. That is, the heating means 103 may be a sheathed heater, gas, or the like in addition to the heating coil.

(Embodiment 4)
FIG. 8 illustrates an induction heating cooker as the heating cooker according to the fourth embodiment of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in the figure, the heating cooker in the present embodiment includes an inner heating coil 801, an outer heating coil 802, and a convection mode changing unit 803, and the convection mode changing unit 803 allows the inner cooking coil 801 and the inner heating coil 801 in the outer convection mode. The outer heating coil 802 is heated by a heating coil connected in series to the high-frequency power supply means, and is heated by the coil of the outer heating coil 802 in the inner convection mode. Other configurations are the same as those in the first embodiment.

  Note that this configuration can be easily realized by using switching by a switch for the convection mode changing means 1003.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the user puts the object to be cooked 101 into the object to be heated 102 and instructs the warming start of the object to be cooked 101, the control means 109 causes the convection mode changing means 803 to widely cover the lower surface of the object to be heated 102. Instruct. Here, the convection mode changing means 803 sets the following heating coil configuration for each convection mode. In the outward convection mode (FIG. 9A), the inner heating coil 801 and the outer heating coil 802 are connected in series to the high frequency power supply means 104 for heating, and in the inward convection mode (FIG. 9B). Heat with outer heating coil. With this heating coil configuration, convection control can be performed in which the convection direction is set inward and outward (FIG. 9). Next, the control means 109 operates the high-frequency power supply means 104 to supply high-frequency power to the heating coil configuration prepared by the convection mode changing means 803, thereby generating a high-frequency magnetic field in the heating coil, and Induction heating is performed. Here, the bumping possibility determination means 108 determines the possibility of bumping occurrence based on the operation described in the first embodiment. If there is no possibility of bumping occurrence, heating is continued, and it is determined that there is a possibility. For example, the following convection control is performed.

  Convection is a phenomenon that continues as the cycle of water rises because the specific gravity becomes lighter when the water is warmed, and then rises and enters the vacant space, so if you want to obtain a large convection, Rather than the whole lower part generating heat, it can be said that when the lower heating part is biased, it is easy to generate a large circulation because the moving fluid rises and falls.

  On the other hand, in order to reduce the possibility of bumping, it is necessary to break the heated object precipitation layer 201 shown in FIG.

  Therefore, when it is determined that there is a possibility of bumping, the convection mode changing unit 803 switches the configuration of the heating coil to the inward convection mode (FIG. 9B) that is the configuration of the outer heating coil 802, so By generating a large convection in the object 102, a flow for breaking the heated object precipitation layer 201 is generated to reduce the possibility of bumping.

  If there is a possibility of bumping even after a predetermined time (for example, 5 seconds), the inward convection mode and the outward convection mode are alternately switched at predetermined time intervals (for example, every 5 seconds) to be heated. An operation of shaking the state of the material precipitation layer 201 is performed.

  As described above, in the present embodiment, when the bumping possibility determination unit 108 determines that there is a possibility of bumping, the convection mode changing unit 803 performs convection control, and the heated object precipitation layer that is the cause of bumping By performing the operation for breaking 201, the possibility of occurrence of bumping can be reduced.

  In the outward convection mode, the inner heating coil 801 and the outer heating coil 802 are connected to the high-frequency power supply means 104 in series and heated. In the inward convection mode, heating is performed by the outer heating coil. In the mode, heating may be performed by the inner heating coil 801, and in the inward convection mode, heating may be performed by the outer heating coil.

  Furthermore, in the present embodiment, when it is determined that there is a possibility of bumping in the cooker that is first controlled in the outward convection mode, the convection mode changing means 803 is switched to the inward convection mode. When it is determined that the cooker controlled in the convection mode is likely to bump, the convection mode changing unit 803 may be switched to the outward convection mode.

(Embodiment 5)
FIG. 10 shows a block diagram of a heating cooker in the fifth embodiment of the present invention.

  The basic operation of the heating cooker in the fifth embodiment is the same as that in the fourth embodiment.

  Here, when the user starts cooking, when cooking fried food, fried food, etc., the cooking mode selection hand 703 is set so that convection control by the convection mode changing means 803 is not performed unintentionally. By using it and allowing the user to select a cooking mode for warming up, convection control using the bumping possibility determining means 108 and the convection mode changing means 803 can be performed only when necessary.

  As described above, in the present embodiment, the cooking mode selection unit 703 performs the heating control using the bumping possibility determination unit 108 and the convection mode change unit 803 only when the user selects a cooking mode in which warming is performed. By making it operate, heating control can be performed only when necessary.

  As described above, the heating cooker and the program thereof according to the present invention can perform heating control according to the possibility of bumping, can suppress bumping phenomenon, and can eliminate spilling and the like. It can be applied to all cooking devices regardless of the heat source. For example, even in an apparatus that heats by applying a flame generated by burning gas to an object to be heated, it can be applied by appropriately setting the heating amount relative rank according to the size of the flame.
