Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to electric cooking appliances such as hot plates.

BACKGROUND OF THE INVENTION A conventional electric cooker of this type is, for example, the
As shown in Japanese Patent No. 166, the structure was as shown in FIG. That is, a first heater 32 that heats the entire surface of the cooking plate 31;
and a second heater 33 that is disposed inside the cooking plate 31 and heats a part of the cooking plate 31, and the two types of heaters 32
．． 33 terminal parts 34 are concentrated in a part of the outer part of the cooking plate 31, and the heat sensitive part of the temperature regulator 36 is arranged between the terminal parts 34.

Problems to be Solved by the Invention However, in such a structure, since the second heater 33 is provided inside the first heater 32, the terminal portion 34 must be concentrated in a part of the outer portion, or Alternatively, there is no choice but to arrange the terminal part 34 of the first heater 32 at the outer part and the terminal part 34 of the second heater 33 at the central part, and the first problem is that the terminal part 34 protrudes outward. For,
The problem was that the outer casing was larger.

A second problem is that the electrical wiring becomes complicated and the cost becomes high. Furthermore, in such a configuration, since the overlapping portion 36 of the two heaters 32 and 33 exists for a long time, material loss in this portion is large and the price is also high. Furthermore, during cooking, a second heater 33 is used to heat half the surface and keep the other half warm. There was a problem in that the coating layer deteriorated and only one side became stuck at an early stage.

The present invention has been made to solve such problems, and its first purpose is to provide a configuration in which the terminal portions of the two heating elements can be concentrated without being placed outside the cooking plate; Another object of the present invention is to provide an electric cooker which can have a smaller outer casing and is inexpensive in price by having a structure that eliminates overlapping parts.

The second purpose is to create a structure in which each heater installed on each half of the cooking plate can be controlled to supply electricity to each other, so that even when heating one side and keeping the other side warm, they can be used alternately to improve the surface coating. The purpose is not only to completely prevent deterioration, but also to be able to cook at different cooking temperatures simultaneously on the same cooking plate.

Means for Solving the Problems In order to achieve the above first object, the present invention provides a heating element,
The heat shield is divided into two pieces near the center, and a switch installed on the outer casing allows switching between parallel energization of both heating elements and energization of the heating element on the temperature controller side. It is something.

Furthermore, in order to achieve the second object, the present invention makes it possible to switch the energization of the heating elements between parallel energization of both heating elements and energization of each individual heating element, and the temperature controller is also compatible with each heating element. A plurality of heating elements are provided, and energization of each heating element is controlled.

Function The electric cooker of the present invention has the above-described configuration, so that the terminal of the heating element does not protrude outward from the cooking plate.
Not only can the outer casing be made smaller, but also the terminals of the two heating elements can be arranged in a concentrated manner, making wiring easier and reducing costs. Becomes cheaper. Furthermore, since there is only a small overlap between the two heating elements, there is less material loss and the product is inexpensive. In addition, since all the heating elements can be used individually, not only can cooking at different cooking temperatures be performed at the same time, but the electric cooker can have a long life without deteriorating the partial cooking plate surface coating by using it alternately during half-heat cooking. It is something that can be done.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1, 2, and 3, below the cooking plate 1, there are a first heating element 3 and a second heating element 4, each having a terminal portion 2 disposed approximately in the center of the cooking plate 1. It is provided. The heating elements 3.4 are each held by a lower heat shield plate 6. Further, the temperature regulator 6 controls the temperature of the cooking plate 1 when the first heating element 3 and the second heating element 4 are energized simultaneously, which is controlled by the changeover switch 7, and the temperature of the cooking plate 1 when only the first heating element 3 is energized. This controls the temperature of the cooking board 1 when electricity is applied. Further, the first heating element 3 is set to have a higher power than the second heating element 4, so that the feeling of firepower during half-sided heating is not impaired. Note that 8 is an outer casing that covers the outside of the heat shield plate 6.

The operation of the above configuration will be explained next.

The cooking plate 1 is heated by changing the changeover switch 7.

It is possible to perform full-surface heating by simultaneously energizing the first heating element 3 and second heating element 4 in parallel, and half-surface heating by energizing only the first heating element 3. In this case, due to the action of the temperature controller 6, , temperature control is performed according to each state. At this time, in one embodiment of the present invention, the terminal portion 2 of each heating element 3.4 can be arranged in the center of the cooking plate 1 in the form of one heating element. Therefore, the terminals do not protrude from the side surface of the outer casing 8, and the outer casing 8 can be made smaller. Further, even in such a state, the terminal portions 2 can be arranged in a concentrated manner, so that wiring processing is easy and assembly can be performed at low cost. Furthermore, with such a configuration of the heating element 3.4, there is no overlapping part 36 of the two types of heating elements, the first heating element 32 and the second heating element 33, which is conventional, so material loss is reduced. This results in an even cheaper configuration.

Next, a description will be given of the effect when each of the heating elements 3 and 4 shown in the other embodiments shown in FIGS. 4 and 5 is provided with a temperature regulator 6. That is, energization control of the heating elements 3 and 40 is controlled by a switch 9 and a temperature regulator 6 provided respectively. Therefore, even when cooking on one side and keeping warm on the other side, by switching the switch 9, you can use the switch 9 alternately each time you use it. There is no deterioration of the coating, and as a result, the sticking life can be improved. Furthermore, by changing the set temperature of each temperature controller 6, cooking at different cooking temperatures can be performed at the same time.

The effect of the invention is achieved by dividing the heat shield plate into two pieces at approximately the center, resulting in less material loss for the heat generating element and an inexpensive structure. In addition, the terminals of the heating element can be concentrated in the center, making wiring easier and cheaper, and since the terminals do not protrude outward, the outer casing can be made smaller. It is something that can be measured.

Furthermore, since it is possible to control the energization and temperature corresponding to each individual heating element, even when cooking on one side and keeping warm on the other side, the life of the surface coating can be extended by heating the cooking surfaces alternately. By changing the set temperature of each temperature controller,
It is also possible to perform cooking at different cooking temperatures at the same time.
