Description

[Detailed description of the invention] The present invention relates to an electric cooking device such as a hot plate, and particularly an electric cooking device that improves the efficiency of using the cooking surface by configuring the cooking surface into multiple temperature zones, and also improves the ease of use. It is an attempt to provide a vessel.

As shown in FIG. 6, a conventional electric cooker of this kind is equipped with a sheathed heater 2 that heats the entire cooking surface almost uniformly on a plate 1 having a cooking surface, and a terminal of this sheathed heater 2 is attached to the plate 1 having a cooking surface. A temperature regulator 3 for controlling the energization of the sheathed heater 2 was detachably provided in the section.

In this configuration, the cooking surface of plate 1 has a nearly uniform temperature over the entire surface as described above, which is convenient when cooking food repeatedly by arranging the food on the entire cooking surface, but when cooking food with different cooking temperatures at the same time. It is not possible to keep cooked food warm while cooking it again.

The present invention solves the drawbacks of the conventional electric cooking appliances mentioned above, and one embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In Figures 1 to 4, 4 is a plate constructed by die-casting a good thermal conductor such as an aluminum alloy.The surface of this plate 4 is coated with fluororesin, and there are two large and small plates. Sheathed heaters 5 and 6 are buried.

The first sheathed heater 5 heats the entire cooking surface of the plate 4, and the second sheathed heater 6 is provided inside the first sheathed heater 5 and heats a part of the center of the plate 4. do.

Here, as shown in FIG. 3, the first sheathed heater 5 and the second sheathed heater 6 have a width a of the conductive part A that is built up on the sheathed heater 5, and a conductive part B that is built up on the sheathed heater 6. is provided on the back surface of the plate 4 with a reduced width.

That is, the heat 5a generated by the sheathed heater 5 spreads over a wide range, but the heat 6a generated by the sheathed heater 6 is transmitted only to a narrow range.

Reference numeral 7 denotes a temperature regulator electrically connected to the terminals of the sheathed heaters 5 and 6 in a detachable manner. control.

FIG. 5 shows another embodiment of the present invention. In FIG. 5, 24 is a plate, 25 is a first sheathed heater that heats the entire cooking surface, and 26 is a first sheathed heater. This is a second sheathed heater that is disposed inside the cooker 25 and heats a part of the cooking surface of the cooker.

Both the first sheathed heater 25 and the second sheathed heater 26 are configured to be bonded to the plate 24 with good heat conductivity. The junction width F, which is the conductive part of the sheathed heater 26, is configured as E>F.

In the above configuration, when cooking many foods at once, the changeover switch 8 is switched between the first sheathed heaters 5 and 2.
Switch to energize 5.

As previously described, these sheathed heaters 5 and 25 are placed at a position that roughly bisects the center of the cooking surface of play 1-4.24 and the end surface of the cooking surface, and heats the entire cooking surface almost uniformly. .

In this case, start cooking by arranging the food on almost the entire cooking surface.

On the other hand, when cooking a small amount of food such as a light meal, or when cooking food that has progressed through the above-mentioned full-surface heating process and is keeping the cooked food warm and preparing new food, the central part 6' of the cooking surface of the selector switch 8 is turned off. Switch to energize the second sheathed heater 6.26.

That is, the width of the conductive portion of the second sheathed heater 6.26 is narrower than the width of the conductive portion of the first sheathed heater 5, 25.

Therefore, the heating range of the cooking surface by the second sheathed heater 6.26) 4.24 does not extend as widely as the heating range of the first sheathed heater, but only a part 6' which is the center of the cooking surface. This makes it possible to heat almost uniformly at an appropriate temperature.

In addition, the peripheral portion of the cooking surface that is not heated can be kept warm by some heat conduction by the second sheathed heater.

In addition, when families with children have meals, they have to check to see if the yarn is properly twisted, and there is a risk of getting burned at the edge of the plate, and there is also the disadvantage of putting it on a plate, etc. The temperature is not very high, so if you move the food cooked in the center of the cooking surface to the heat-retaining area around the cooking surface, you can freely eat whatever you like and always enjoy it.

Furthermore, the electric capacity of the second sheathed heater is set to
Even if the wattage is set to be as low as the cooking area heated by the second sheathed heater relative to the cooking area heated by the second sheathed heater, the heat generated by the second sheathed heater will be distributed over the center of the cooking surface as described above. It heats the food at an appropriate temperature, making it possible to save electricity when cooking small amounts.

As described above, according to the present invention, the plate I having a cooking surface
- providing a first heater that heats the entire cooking surface;
A second heater that heats a part of the cooking surface is disposed inside the first heater, and the width of the conductive portion of each heater to the plate is set so that the second heater Because of its small size, the first heater can heat the entire cooking surface, and the second heater can heat the center of the cooking surface almost uniformly at an appropriate temperature. It is expensive, easy to use, and has great practical value.
