(Embodiment 1)
FIG. 1 is a block diagram of a heating cooker according to the first embodiment of the present invention.

  In FIG. 1, 101 is an object to be cooked, 102 is an object to be heated, 103 is a heating coil, 104 is a high-frequency power supply means for performing induction heating using the heating coil 103, and 105 is a temperature under the object to be heated. First temperature measuring means 106 is a bumping sign detecting means 106 that detects a sign of bumping phenomenon, 107 is a high-frequency power supply means 104 that suppresses bumping when the bumping sign detecting means 106 detects a sign of bumping phenomenon It is the control means which controls to do.

  The bumping sign detection means 106 is a sign of bumping when the temperature of the first temperature measuring means 105 is lowered even though the object to be heated 102 is heated by the heating coil 103. Is detected. A pan is used as the object to be heated 102, a temperature sensor such as a thermistor is used as the first temperature measuring means 105, an induction heating inverter is used as the high frequency power supply means 104, a microcomputer is used as the bump sign detection means 106, and the control means 107. Thus, this 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.

First, a situation where bump boiling suppression control is required will be described with reference to FIG. In FIG. 2, 201 is a cause of gas phase generation, and 202 is a gas phase. When the object to be heated 102 is heated from the high-frequency power supply means 104 through the heating coil 103 according to the user's instruction (FIG. 2A), the bottom of the object to be heated 102 such as a pan is in a clean state with no scratches. When the object to be cooked 101 is a thick viscous material or pure water, there is no core of boiling for generating bubbles, so the object to be cooked 101
Does not change from the liquid phase to the gas phase, and may be in an overheated state in which it remains in the liquid phase even if the boiling point is exceeded in the region in the vicinity of the object to be cooked 101 and the object to be heated 102 (FIG. 2 ( b)). In this state, when the object to be heated 102 such as a pan is vibrated or a powdery seasoning is introduced (FIG. 2 (c)), the overheating has the conditions for boiling at any time. The region of (2) is gas-phased at a stroke due to the occurrence, and becomes a large bubble, and the ejection bumping phenomenon occurs (FIG. 2 (d)).

  Here, FIG. 3 shows the measured temperature output of the temperature measuring means 105 over time when this bumping phenomenon occurs, and the state shown in FIGS. 2A to 2D on which the measured temperature output corresponds. Indicates what to do. While in the overheated state, the temperature measured by the first temperature measuring means 105 rises, but once the temperature drops, the temperature drops once. This is because heat of vaporization (about 540 calories per gram in the case of water) is consumed as energy for changing the liquid into a gas. That is, not only the energy input from the high-frequency power supply means 104 to the object to be heated 102 through the heating coil 103 but also the energy that the object to be heated 102 holds as the heat capacity equivalent is consumed in the gas phase and is being heated. Nevertheless, it is observed as a phenomenon that the temperature decreases.

  Here, the operation of performing bumping suppression control will be described with reference to FIG. 4, taking this temperature drop as a sign of occurrence of bumping phenomenon.

  By performing bumping suppression control that limits the energy input from the high-frequency power supply means 104, it is possible to suppress a large amount of vaporized region from being generated at once. The operation at this time will be described with reference to FIG. When the user gives an instruction to turn on the power, the control means 107 turns on the object to be heated 102 through the heating coil 103 by the high-frequency power supply means 104 (S401). The bumping sign detection means 106 confirms whether or not the measured value of the first temperature measuring means 105 is a bumping sign detection start condition (for example, 90 ° C. or higher) (S402), and starts the sign detection if the sign detection start condition is met. The bumping sign detection means 106 obtains the temperature from the first temperature measuring means 105 (S403), compares the current measurement temperature with the previous measurement temperature (the initial value of the previous measurement temperature is the temperature at the start of heating), and indicates the bumping sign. It is confirmed whether or not a certain temperature drop has occurred (S404). If no temperature drop has occurred, the sign start flag is set to 0 (S405), the current measured temperature is stored as the previous measured temperature (S411), and the temperature measurement is repeated thereafter to continue the sign detection. If a temperature decrease has occurred (S404), if the sign start flag is 0 (flag 0 = immediately after the start of decrease), the sign start temperature is updated with the current measured temperature, and the sign start flag is set to 1 (flag 1 = continuing decrease) ) (S405). Here, if (current measurement temperature−indication start temperature) is calculated and there is a temperature drop of a predetermined value (eg, 5 ° C. drop for 3 seconds) or more (S408), the bumping suppression heating control (eg, heating stop) is performed (S409). ) Continue for a predetermined time (for example, 3 seconds) (S410). Thereafter, the previous measurement temperature is overwritten with the current measurement temperature, and while the sign start flag and temperature are updated, the above-described bump boiling sign detection operation is continuously performed until the heating is completed (S412).

  As described above, in the present embodiment, the sign that the phase transition from the liquid to the gas is rapidly progressed, the heat of the object to be heated is lowered by the heat of vaporization, despite the heating. As a phenomenon to be performed, the bumping sign detection unit 106 uses the temperature measurement unit 105 to detect the bumping occurrence by performing heating control that adjusts the electric power supplied by the high-frequency power supply unit 104.

  It should be noted that in this embodiment, an explanation was given using a sudden temperature drop as the bumping sign detection operation, and FIG. A sudden temperature rise after observing such a sudden temperature drop may be detected to detect a bump sign.

FIG. 5 shows a block diagram of a heating cooker according to the second embodiment of the present invention. In FIG. 5, reference numeral 501 denotes a second temperature measuring means. This configuration can be easily realized by using a thermistor for the second temperature measuring means 501.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. In the drawings, the same reference numerals are given to portions showing the same operations as those in the first embodiment.

  As shown in FIG. 5, in the present embodiment, the second temperature measuring means 501 is arranged at a position different from the first temperature measuring means 105. In the induction heating cooker, when the high-frequency power supply means 104 generates heat to the heated object 101 through the heating coil 103, it is difficult to make the distribution of heat generation completely uniform. When cooking is performed on a food having a high viscosity and a non-uniform temperature distribution, convection starts from a location with a large amount of heat generation. In such a case, the portion of the cold cooking object that has not yet been heated is mixed by convection, and the temperatures of the first temperature measuring means 105 and the second temperature measuring means 501 are greatly reduced locally. In such a case, the temperature measured by the first temperature measuring means 105 and the second temperature measuring means 501 heats the object to be heated 102 by the heating coil 103 in order to prevent erroneous detection of the bumping sign by the bumping sign detection means 106. In the case where it falls, the bumping sign detection means 106 determines that it is a sign of bumping and performs bumping suppression control to prevent erroneous detection.

  By the operation as described above, when both the first temperature measuring means 105 and the second temperature measuring means 501 are lowered in temperature, the bumping sign detection means 106 determines the bumping sign and performs bumping suppression control. Thus, it is possible to provide a heating cooker capable of detecting bumpy signs more accurately.

(Embodiment 3)
FIG. 6 shows a block diagram of a heating cooker according to the third embodiment of the present invention. In FIG. 6, reference numeral 602 denotes cooking mode selection means, 603 denotes bumping suppression control execution display means, and 604 denotes bumping suppression control release selection means. The cooking mode selection means 602 uses a microcomputer, the cooking mode selection means 602, the bumping suppression control release selection means 604 uses a switch and a microcomputer, and the bumping suppression control execution display means 603 uses an LED to facilitate this configuration. Can be realized.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. In the drawings, the same reference numerals are given to portions showing the same operations as those in the first and second embodiments.

  Upon detection of a sign of bumping by the bumping sign detection means 106, the control means 107 periodically (for example, every 3 seconds) changes power (duty control), for example, ± By waking up at 200 W, turbulent flow can be caused while maintaining the user instruction power on average, and gentle boiling can be promoted without abrupt fluctuations in the amount of heating.

  Further, when the user starts cooking, when cooking fried food, fried food, etc., warming is performed using the cooking mode selection means 602 so that sudden boiling suppression control is not performed unintentionally. By allowing the user to select the cooking mode, bump boiling suppression control using the bump sign detection means 106 can be performed only when necessary.

Further, the bumping suppression control execution display unit 603 displays that the bumping sign detection unit 106 has detected the sign, thereby prompting the user to stir effectively for bumping suppression. Further, by performing the suppression control execution display, it is possible to inform the user of the heated object 102 that is likely to cause bumping.

  In addition, when the user does not want to automatically adjust the heating power and requests a constant power input, the bumping suppression control release selection unit 604 can be selected not to operate the suppression control using the bumping sign detection unit 106. And Thereby, although automatic heating control is normally performed so that bumping does not occur, it can be intentionally prohibited according to a user's request.

  As described above, in the present embodiment, when the sign of bumping detection is detected by the bumping sign detection unit 106, power fluctuation (duty control) is caused by the control unit 107 to promote gentle boiling, and the heating amount is rapidly increased. The bumping suppression control can be performed gently without fluctuation. Further, by detecting the bumping sign by the bumping sign detection unit 106 only when the cooking mode to be heated is selected by the cooking mode selection unit 602, the bumping suppression control operation is performed only when cooking that requires bumping suppression is performed. be able to. In addition, by notifying the fact that the suppression control has been performed by the bump boiling suppression control execution display unit 603, it is possible to not only execute the suppression control but also agitate by the user's hand effective in bump bump suppression. Further, when the user requests heating with a constant power by the bump boiling suppression control release selection means 604, the bump boiling sign detection means 106 does not detect the bump boiling sign detection so that the heating is performed in accordance with the user's intention. Control can be performed.

  In addition, the means described in the first to third embodiments are provided with hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electrical / information device including an I / O, a computer, a server, and the like. You may implement in the form of the program made to cooperate.

FIG. 9 illustrates an induction cooking device as a cooking device in Embodiment 4 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 according to the present embodiment includes an inner heating coil 901, an outer heating coil 902, and a convection mode changing unit 903, and the convection mode changing unit 903 and the inner heating coil 901 in the outer convection mode. The outer heating coil 902 is connected in series to the high-frequency power supply means, and the outer heating coil 902 is configured 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 903.

  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 to start heating the object to be cooked 101, the control means 109 causes the convection mode changing means 903 to widely cover the lower surface of the object to be heated 102. Instruct. Here, the convection mode changing means 903 sets the following heating coil configuration for each convection mode. In the outward convection mode (FIG. 10A), a heating coil configuration in which the inner heating coil 901 and the outer heating coil 902 are connected in series to the high-frequency power supply means 104 is used, and the inward convection mode (FIG. 10B). Then, the heating coil structure of an outer side heating coil is provided. With this heating coil configuration, convection control can be performed in which the convection direction is set inward and outward (FIG. 10).

  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 bump boiling sign detection means 106 performs bump bump sign detection based on the operation described in the first embodiment. If no sign of bump boiling is detected, heating is continued. If the sign is detected, the following convection is performed. Take control.

  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 eliminate the overheating state shown in FIG.

  Therefore, when a sign of bumping is detected, the convection mode changing means 903 switches the inward convection mode (FIG. 10B) heated by the outer heating coil 902 so that a large convection is generated in the heated object 102. And a large flow for eliminating the overheating state is generated to reduce the possibility of bumping.

  In order to reduce the possibility of bumping, not only the inward convection mode, but also the inward convection mode and the outward convection mode are alternately switched at a predetermined time period (for example, every 30 seconds). Fluctuation may be given to the bottom of the object to be heated.

  As described above, in the present embodiment, when the bumping sign detection means 106 detects the sign of bumping, the convection mode changing means 903 performs convection control to eliminate the overheating state that causes bumping. By performing the operation, the possibility of bumping can be reduced.

  In the outward convection mode, the inner heating coil 901 and the outer heating coil 902 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 901, and in the inward convection mode, heating may be performed by the outer heating coil 902.

  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 unit 903 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 903 may be switched to the outward convection mode.

FIG. 11 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 602 is set so that convection control by the convection mode changing means 903 is not performed unintentionally. By using it and allowing the user to select a cooking mode for warming up, convection control using the bump sign detection means 106 and the convection mode change means 903 can be performed only when necessary.

  As described above, in the present embodiment, the cooking mode selection means 602 operates the heating control using the bump boiling sign detection means 106 and the convection mode change means 903 only when the user selects a cooking mode for warming up. By doing so, heating control can be performed only when necessary.

As described above, the cooking device according to the present invention is such that heating of an object to be cooked such as water in the object to be heated such as a pan is performed quietly, and there is no trigger for phase transition from liquid to gas. Phase transition is promoted when a physical impact is applied to the pan that is to be heated or a powder seasoning that is the core of boiling is added when the overheating state exceeds the boiling point of In response to a bumping phenomenon in which boiling rapidly progresses and a large bubble is suddenly generated, the bumping sign detection means is deprived of heat by the heat of vaporization. It is possible to suppress the occurrence of bumping by capturing the decrease in the temperature of the heated object by using the temperature measuring means and performing the heating control to adjust the electric power supplied by the high frequency power supply means.

  This operation can achieve the same effect by changing the size of the flame even in an apparatus that heats the object to be heated by applying a flame generated by burning the gas.
