Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric cooking device such as a hot plate for general household use.

BACKGROUND OF THE INVENTION A conventional electric cooker of this type is, for example, the
As shown in Publication No. 232, the structure was as shown in FIG. 3. That is, a heat generating element 2 provided on the back surface of the cooking board 1, a heat sensitive block 6 provided between the terminals 3 of this heat generating element 2 and having a heat sensitive hole 4, and a temperature sensing element 6 inserted into the heat sensitive hole 4. , and a temperature regulator 7 which controls the temperature of the cooking plate 1 and has a connection terminal (not shown) electrically connected to the terminal 3 of the heating element 2.

Furthermore, recently, an electric cooker having a configuration as shown in FIGS. 4 and 5 has been proposed. That is, the cooking plate 1 is constructed by a heating element 2 provided on four sides of the cooking plate 1, a heat-sensitive block 5 provided on the outside of the heating element 2, and a temperature sensing element 6 in contact with the lower surface of the heat-sensitive block 6. An electric cooking device has also been proposed, which includes a temperature cooking device that performs temperature control.

Problems to be Solved by the Invention However, in the conventional example shown in FIG.
In order to improve the temperature distribution of the cooking plate 1, a connecting terminal (not shown) electrically connected to the terminal 3 of the heating element 2 protruding to a position near the outer periphery of the cooking plate 1 is connected to a temperature sensor having a temperature sensing element 6. Since it is provided integrally with the regulator 7, it is difficult to position the temperature regulator 7 on the inside of the cooking plate 1 on the wiring, and as a result, it is difficult to accurately sense the temperature near the center of the cooking plate 1. In addition, the temperature regulator 7 protrudes from the cooking plate 1, resulting in an unsightly appearance.

Furthermore, in the conventional examples shown in FIGS. 4 and 6, as in the conventional example shown in FIG. As a result, since only the temperature of the cooking plate 1 outside the heating element 2 is sensed, there is a problem that accurate temperature sensing is difficult, and the amount of protrusion of the temperature regulator 7 from the cooking plate 1 is reduced. Therefore, when the temperature regulator 7 is located inward of the cooking plate 1, the heating element 2 is also located inward at the same time, resulting in a problem that the temperature distribution on the cooking plate 1 becomes poor. Was.

An object of the present invention is to provide an electric cooker that solves these problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a cooking plate with a heating element provided on the back surface, and a cooking plate provided on at least one end of both sides of the heating element, and a heating element provided on the bottom surface of the heating element. It is composed of a heat-sensitive block having a heat-sensitive hole at the bottom, and a temperature regulator in which a temperature-sensing element is inserted into the heat-sensitive hole and controls the temperature of the cooking plate.

According to the above configuration, the temperature sensing element can be inserted to the inner position of the heating element, so the temperature sensing position can be set near the center of the cooking plate, and as a result, accurate temperature sensing is possible, Not only does this reduce the amount that the temperature regulator protrudes from the cooking plate, improving its appearance, but it also allows the position of the temperature sensing element to be determined regardless of the position of the heating element. Due to the temperature distribution of the cooking plate,
It can be set at the optimum position.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, reference numeral 11 denotes a cooking plate, and a heating element 12 is integrally provided on the back surface of this cooking plate 11. 13 is a terminal of the heating element 12, and this terminal 13 is connected to an external electrical connection member (not shown). 14 is a heating element 12
The heat-sensitive block 14 is fixed to the cooking plate 11 with a fixing member 16 such as silver solder. A heat-sensitive hole 16 is provided. 17
is a heat insulating layer interposed between the heat generating element 12 and the heat sensitive block 14, and this heat insulating layer 1 is provided to prevent the heat of the heat generating body 12 located below the heat sensitive block 14 from being supplied to the heat sensitive block 14 in excess. It is. -118 is a temperature sensing element that is inserted into the heat sensitive hole 16 of the cooking plate 11 and senses the temperature of the cooking plate 11, and a switch (not shown) that controls the temperature of the cooking plate 11 in conjunction with the temperature sensing of the temperature sensing element 18. ) are integrally provided to constitute the temperature regulator 19. The amount of insertion of the temperature sensing element 18 into the heat sensitive hole 16 is set such that the temperature sensing element 18 is inserted at least to the inside of the outer wall of the heat generating element 12 and the heat sensitive block 14 is influenced by the heat on the inner wall side of the heat generating element 12. ing.

The operation in the above configuration will be explained. electrically connecting the terminal of the heating element 12, the external electrical connection member, and the temperature regulator 19;
When electricity is applied, the heating element 12 generates heat, and the cooking plate 11 is heated. In this case, the electric cooker according to the embodiment of the present invention is provided with a heat-sensitive hole 16 that is located below the heat-generating element 12 and into which the temperature-sensing element 18 can be inserted up to the inside of the heat-generating element 12. The amount by which the cooking plate 19 protrudes from the cooking plate 11 is reduced, resulting in an excellent appearance. Further, the heat-sensitive hole 16 is located on the cooking plate 1 inside the heating element 12.
Since the temperature sensing element 18 is provided in the heat-sensitive block 14 which can absorb heat from 1, the temperature sensed by the temperature sensing element 18 can sense the temperature at a more central position of the cooking plate 11, and as a result, it is more accurate. Not only is temperature sensing possible, but since cooking is usually done at the center of the cooking plate 11, the temperature of the food to be cooked is also good. Also heat sensitive - block 1
Since the heat insulating layer 17 is provided between the heating element 12 and the heating element 12, the temperature rise of the heat sensitive block 14 is less affected by the heating element 12, and as a result, the temperature of the cooking plate 11 can be sensed more accurately. be able to. Furthermore, as described above, since the insertion position of the temperature sensing element 18 is not on the same plane as the heating element 12, the position of the heating element 12 can be set regardless of the position of the temperature sensing element 18, and as a result, The heating element 12 is placed at an optimal position with good temperature distribution relative to the cooking plate 11.
can be set.

In the above embodiment, the heat-sensitive block 14 is provided by fixing a separate member, but it may be formed integrally with the cooking plate 11, and the heat-sensitive block 14 is fixed to both sides of the heating element 12. However, either one can be fixed to the other. Further, although the heat insulating layer 1a is provided over the entire surface between the heat generating element 12 and the heat sensitive block 14, the same effect can be obtained even if a portion thereof comes into contact with the heat insulating layer 1a.

Effects of the Invention As is clear from the above description, according to the present invention, a heat-sensitive block provided at at least one end of both sides of a heat-generating element provided on a cooking board and having a heat-sensitive hole below the bottom surface of the heat-generating element, Since the temperature sensing element of the temperature controller is inserted, the temperature sensing element can be inserted regardless of the heating element, and by inserting the temperature sensing element deeply, the amount of protrusion of the temperature controller from the cooking plate can be reduced. This makes it possible to reduce the number of heating elements, resulting in a good appearance, and the position of the heating element can be set at any position on the cooking board, so it is possible to reduce the number of heating elements when inserting the temperature sensing element. It is possible to obtain a device that does not have a drop in temperature distribution due to position determination.

Furthermore, the heat sensing element can sense the temperature of the cooking plate inside the heating element, so it not only can accurately sense the temperature, but also adapts to the cooking condition of the food and has a good thermal response. It is something that can be controlled.
