TECHNICAL FIELD OF THE INVENTION
The present invention relates to a heating cooker having an electric resistance heating type heater, and more particularly to improving safety against unexpected input to the heating heater.
[0002]
[Prior art]
Conventionally, there has been a heating cooker of this type as shown in FIG. FIG. 8 shows a so-called three-port heating cooker having three heating units used in the kitchen of a general household in Japan. FIG. 9 shows details of the operation unit.
[0003]
A top plate 2 made of a heat-resistant glass is provided on a top surface of a main body 1 constituting an outer shell of the cooking device with an outer peripheral portion covered by a top frame 3. On the lower surface of the top plate 2 in the main body 1, an induction heating coil 4 for performing induction heating, and a radiant heater 5 having a nichrome wire or the like which generates heat by electric resistance are arranged. On the surface of the top plate 2, respective heating means are provided. The heating circle 6 is printed corresponding to the position where the heating circle 6 is provided. Reference numeral 7 denotes a roaster unit for baking fish and the like, which has a roaster heater that generates heat by electric resistance. At the front of the main body 1, there are provided a fixed type such as a dial type or a push button type or an opening / closing storage type operation unit 8 as shown in the figure, and a display unit 9 for displaying various states according to the operation.
[0004]
In the operation unit 8, an induction heating coil input on / off button 10, a radiant heater input on / off button 11, a roaster heater input on / off button 12, and respective heating power increase / decrease buttons are provided so that the operation of each heating means can be performed smoothly. 13 and the like are arranged.
[0005]
FIG. 10 shows one that improves the convenience of the operation. As shown in the figure, in this cooker, an operation unit 15 of an induction heater unit of a capacitance type is arranged in front of a top plate 14 (for example, see Patent Document 1).
[0006]

[Problems to be solved by the invention]
However, in such a conventional configuration, since the operation portion 8 provided on the front side surface portion and the top plate 2 for cooking are separated from each other, the cook can operate the operation portion separated from the cooking container during the operation during cooking. It was necessary to move the line of sight to 8 and operate the cut / on button 10 and the like. In addition, there is a problem in operability such that the operation unit 8 must be operated while changing its posture because it is at a low position.
[0008]
Further, in the conventional configuration in which the operation unit 15 of the induction heater unit of the capacitance type is provided in front of the top plate 14, the operation unit of the radiant heater (heat generation heater by electric resistance) becomes extremely hot as compared with the induction heating unit. Is not on the top plate 14, the risk of the start of heating due to an unexpected operation not noticed by the user is reduced. On the other hand, when the radiant heater 5 is used, the on / off button of the operation unit provided on the front side surface is operated. And it was very inconvenient to use.
[0009]
An object of the present invention is to solve the above-mentioned conventional problems and to provide a cooking device with good operability and high safety and reliability.
[0010]
