Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an electromagnetic cooker.

[Prior art]

Conventional electromagnetic cookers do not have an automatic cooking function, but simply have a temperature control function that allows cooking such as keeping warm or frying, and also a timer type that turns off the set output when the time is up. There were just things like that.

[Problem that the invention attempts to solve]

When cooking something like the above, first put the ingredients and stock into a pot according to the amount, referring to the cooking book in the instruction manual, and heat it at near maximum output to the boiling point. After doing that, switch the output to approximately 500 to 400W and start simmering. Also, at an appropriate time, add roux to curry, stew, etc. while checking the doneness.
Furthermore, it is necessary to perform heating while adjusting the output, and it is troublesome to adjust the output each time. Also, when the power was 500 to 400 W during simmering, the continuous electricity was likely to cause browning on the bottom of the pot, making it necessary to stir occasionally.

[Means for solving problems]

The present invention adds a quantity scale corresponding to the output adjustment scale of the output adjustment volume, and also provides a mode changeover switch for the purpose of stewing cooking, and when the mode changeover switch is selected, a heating sequence corresponding to the quantity scale is set. Heating is performed using the simmer cooking mode.

[Effect]

According to the present invention, by pressing the mode changeover switch, the cooking mode is set to simmering, and at this time, when the output adjustment volume is set to a desired quantity scale, heating is performed in a heating sequence corresponding to the quantity scale. Therefore, there is no need to adjust the output as in the past, and burning is prevented.

〔Example〕

1 is a rectifier stack for full-wave rectification, 2 is a choke coil, 3 is a smoothing capacitor, 4 is a heating coil that heats the load 6 on the top plate 5, and 7 is a resonance capacitor connected in parallel to the heating coil 4. , 8 is a switching element for flowing high frequency alternating current to the heating coil 4, 9 is a damper diode connected in parallel to the switching element 8, 10
1 is a drive circuit that turns on and off the switching element 9 based on a control signal from the control circuit 11;
2 is a power supply circuit, 13 is a display circuit, 14 is a variable volume for adjusting heating output (output adjustment volume), 15 is a thermistor for detecting the temperature of load 6, and 16 is for simmering cooking. This is a mode switching switch for cooking, and by pressing the switch, the simmering cooking mode is set.
Further, corresponding to the output adjustment scale of the variable volume 14, a quantity scale for serving the stewed dish is added.

The stew cooking mode will be explained below. First of all, stew cooking refers to the cooking of curry, stew, etc., as well as oden, soup, cabbage rolls, satsuma soup, meat jiyaga, etc. The basic heating sequence is to reduce the heat from high to low as shown in Figure 2. After that, the temperature changes from simmering to keeping warm and ends.

The above-mentioned high heat means heating at about 1100W, which is close to the maximum output, and low heat means heating at about 4A with on/off control, changing the power consumption depending on the amount. Also, since simmering is a low heat and most of the cooking is done, it is done with an on/off control of about 3A. The heat retention mode is similar to the conventional heat retention mode, keeping the temperature at approximately 80 to 90 degrees Celsius.
Further, the switching from high heat to low heat is performed by detecting that the water has boiled using an automatic water boiling detection means.

The relationship between low heat time and power consumption is as shown in FIG. 3, where is the energization time for the quantity scale corresponding to the position of the adjustment knob of the variable volume 14, and is the energization rate of the output current 4A. To explain the energization rate in a little more detail, at the "weak" position on the output adjustment scale of the variable volume 14, that is, at the "for 2 people" position on the portion scale, the output is 4A, on for 40 seconds, off for 20 seconds, and then turned on for 1 minute. Heat cycle repeatedly. Also, at the quantity scale "4 people's worth", the output is 4A and the power is turned on for 47 seconds and 13 seconds off, and at the quantity scale "6 people's worth", the output is 4A and the power is turned on for 52 seconds and off for 8 seconds.

In the manner described above, heating sequences corresponding to the portion size scales "for 2 people", "for 4 people", and "for 6 people" are set (as shown in the fourth diagram). That is, by pressing the mode changeover switch 16 and setting the adjustment knob of the variable volume 14 to a desired quantity scale position, the heating sequence shown in FIG. 4 is controlled.
In addition, an alarm is activated between "low heat" and "slow heat" and between "slow heat" and "keep warm" to remind people to add "roux" and to signal the end of simmering. ing.

Therefore, according to the present invention, when you want to perform stewing cooking, first press the mode changeover switch 16 to set the stewing cooking mode, and then set the adjustment knob of the variable volume 14 to the desired quantity scale. The heating sequence (shown in the fourth figure) is automatically performed.

〔effect〕

Since the present invention is configured as described above, it is not necessary to adjust the output each time during simmering cooking, and the simmering cooking can be automatically performed with a heating sequence that suits the amount of food, and the output can also be adjusted. Since a quantity scale is added to correspond to the output adjustment scale of the cooking volume, the output adjustment volume can also be used for simmering.Furthermore, the notification device notifies you when it is time to add seasoning, so you can easily adjust the seasoning. Good cooking conditions can be obtained without delaying the timing of adding ingredients.
