Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating panel used in electric stoves, etc., and its purpose is to accurately control the temperature of a cooking container and improve cooking performance in boiling and grilling. It is something.

In recent years, this type of heating panel has been developed to accommodate multiple heating elements in one panel, and to selectively generate heat at the outer and inner peripheries. There is a strong desire to be able to heat objects from small diameters to small diameter objects in an optimal state. Various heating plates have been proposed to meet this demand, but it is difficult to accurately control the heating temperature, which is an extremely important characteristic of the FLJ heating plate, and obtain good cooked food. I haven't seen a solution. The heating temperature control section generally consists of a temperature sensing section and a control f■3, and in consideration of ease of control and economic efficiency, the temperature sensing section is closely attached to a part of the bottom of the container, and a single controller is installed. In many cases, the temperature was controlled by setting an arbitrary temperature using an adjustment knob or the like connected to this controller. In order to represent the temperature of the container, it is often installed in the center of the container, but this method has the drawback that the ID control temperature differs significantly between large and small diameter containers as mentioned above. was.

For example, to explain specifically when grilling meat, it is usually desirable to control the temperature of the grilling surface to around 200°C, but if you set it to 200°C when using a large container, it will be around 140"C when using a small container. The drawback was that the control was performed at a low temperature, making it unusable for practical use.The above drawback can be corrected by setting the temperature for each container by operating a temperature control knob, etc., but in this case, it is difficult to put it into practical use. There were an extremely large number of types of containers, and the operations were extremely difficult, resulting in problems such as making Ml.

The invention aims to overcome the above-mentioned drawbacks of the conventional art, and embodiments of the invention will now be described with reference to the accompanying drawings.

Figure 1: H In Figure 2, numeral 1 is a heat generating board, with a double outer heat generating part, a double inner heat generating part 3, and corresponding heat generating elements 4,
6, 6, 7, 8.9, and is made of aluminum or cast iron, and its upper surface is smoothed to ensure close contact with the cooking container. Further, a temperature sensing section 10 is provided in the center, and a U-shaped groove 11 for positioning the container is provided near the outer periphery. Next, the state of heat transfer and temperature sensing when a container is heated using this heat-generating plate 1 will be explained with reference to FIGS. 3, 4, and 6. Figures 3 and 4 show the situation with the configuration of 1 norr bundle, and Figure 3 (-1) shows the case where the small garbage container 12 is heated, and Figure 4 shows the case where the large container 13 is heated, respectively. .1 When heating the small container 12, the heating elements 6 and 7
. Therefore, the temperature of the temperature sensing part 10 increases by -F due to both of them, and the electricity supply stops at a predetermined set temperature, but the small container 12 is heated again as the temperature of the temperature sensing part 10 decreases. Hold at temperature. This situation is shown in graph 14 of FIG. Next, the case where the large container 13 is heated will be explained with reference to FIG. In this case, the heating elements 4 and 5 are energized and heat A (as shown by the arrow) is supplied to the temperature sensing section 10 in the same manner as described above, but the heat B conducted inside the heating panel 1 is different from that in the case of the small container. In comparison, the amount of heat is extremely small, and the overall amount of heat supplied to the temperature sensing portion 1o is significantly reduced, resulting in a phenomenon in which the energization is not stopped even though the temperature of the container 13 has risen. As a result, as shown in graph 16 in FIG. 6, the container temperature tends to increase at the 41st stitch compared to the case of the small container 12. FIG. 6 is an embodiment of the present invention, and this figure shows a state in which the large container 13 is being heated. This shows that in addition to the outer circumferential heating elements 4 and 6, the heating elements 9 and 7 near the temperature sensing section are energized in an auxiliary manner. In this case, the temperature sensing part 10-- is supplied with heat A and heat B in a manner similar to the case of the small container 12. Therefore, the container temperature can be controlled at approximately the same temperature as in the case of a small container, as shown in graph 16 of FIG.

As is clear from the above explanation, the present invention can provide a heating plate with extremely excellent temperature controllability regardless of the size of the container, and along with this, the practical baking performance + 7/Ii'1 degree setting can be achieved. The key is to significantly improve operability.

Although the above-mentioned heating element has a concentric shape, it may also be formed in a double-width or triple-width spiral shape. 1[10

It is possible to set the power capacity of the heating element near the kA section and the outer peripheral heating element to 14 distribution Q dimension 110h.
