[Problems to be solved by the invention]
In such a conventional electric stove, two heaters are arranged symmetrically with respect to the center of the main body case, so the heat source during weak operation is only one half of the main body case and the heat generation direction changes. Has a problem that the direction of the main body case must be changed simultaneously with the weak operation switching, and heat generation from the center of the main body case is required even in weak operation.
[0005]
The present invention solves such a conventional problem, and an object of the present invention is to provide an electric stove capable of generating heat from the center of the main body case even in a weak operation.
[0006]
In addition, in a conventional electric stove having a non-red hot heater, the presence or absence of energization is only confirmed with the operation display lamp provided on the top surface of the main body case, and there is a case where it may be left energized. Therefore, it is required that the energized state can be reliably confirmed during operation.
[0007]
The present invention solves such a conventional problem, and an object of the present invention is to provide an electric heater capable of easily visually confirming an energized state.
[0008]
In addition, since the conventional electric stove has two heaters on the left and right of the center of the main body case, there is a problem that the heating range is reduced by half during weak operation with one heater energized, and strong even during weak operation. It is required to have the same heating range as in operation.
[0009]
This invention solves such a conventional subject, and it aims at providing the electric stove which does not change a heating range at the time of weak operation and strong operation.
[0012]
[Means for Solving the Problems]
In order to solve the above problems, the electric stove of the present invention energizes the reflector provided in the main body case, the red and non-red heaters provided in front of the reflector, and the red and non-red heaters. It has an operation switch that controls the strength and switches between strong and weak operation.When operating in strong or weak operation, both the red and non-red heat heaters are energized in strong operation and only the red heater is used in weak operation. The red heater is always energized so as to be energized.
[0013]
And according to this invention, the electric stove which can confirm an energization state visually is obtained by energizing a red heater during operation.
[0014]
Another means is that a red-heated heater is arranged in the center of the main body case, a non-red-heated heater is arranged symmetrically on both sides of the red-heated heater, and a reflector having a parabolic cross section with each heater as a focal point is provided behind each heater. The reflecting plate includes a first reflecting plate for the red heat heater provided behind the red heat heater, a reflecting plate for the non red heat heater provided behind the non-red heat heater, and an outer side of the reflecting plate for the non red heat heater. The second reflecting plate for the red-heat heater is used.
[0015]
And according to this invention, the electric stove which has the heating range which is not different with weak operation and strong operation is obtained.
[0017]
