Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heated dish for an electromagnetic cooker using a general ceramic material.

[0002]

2. Description of the Related Art A known safe electromagnetic cooker has a magnetic force generating coil arranged under a top plate, and an eddy current is generated in a pot on the top plate and a bottom surface of the plate by magnetic lines generated by the magnetic force generating coil. This causes heat to be generated, and has recently come into wide use.

[0003] A heating cooker for an electromagnetic cooker used in such an electromagnetic cooker is: (i) a cooker made of iron, stainless steel or the like made of a magnetic metal material; (A) A material in which iron that generates heat due to electromagnetic induction by high frequency is spray-coated on the back surface of aluminum and heat-resistant coating is applied thereon. (C) A heat-resistant soil with a silver heating element baked on the back of the pot. (D) A heat-resistant soil sprayed with a nickel film on the outside or inside of the pot. (E) Heat resistant soil made of a carbon material adhered to the outside or inside of a pot made of adhesive with an adhesive. Although many things are used, the basic structure is only a thing with a heating part closely attached, and there is no thing made of general pottery in consideration of the characteristics of metal and pottery .

[0004]

(F) Metals and the like are easily rusted and burnt. (G) Because the heating time is too early, it is not suitable for simmering slowly. (H) The heat is easy to cool. (K) Special heat-resistant pots require the latest attention in handling and have high unit prices. (U) Pottery, glass, stone, synthetic resin, etc. that does not generate magnetic force cannot be used. (B) There are few types of shapes and decorative designs, and there are few utensils that can be enjoyed. The present invention has been made to solve these disadvantages.

[0005]

A ventilation hole (4) is made to penetrate an arbitrary place on the bottom surface of a tray (3) made of a non-conductive material. A space (2) is provided on the tray (3), and heat is generated by electromagnetic induction by high frequency.
A heating section (5) is provided in which the heating plate (1) is fixed without being fixed. The heating unit (5) is attached to the outer bottom of the main body (6) formed of a non-conductive material. The present invention is a heated tableware for an electromagnetic cooker having the above configuration.

[0006]

When the present invention is used, a cooker, which is a ceramic cookware, is placed on a top plate of a known electromagnetic cooker and a power switch is turned on. An eddy current is generated by reacting with (1), and the heat generating plate (1) generates heat, and the heat is transmitted to the main body (6) to heat the entire cooking utensil.

As a result, the heat rise is slightly inferior to that of a cookware made of a magnetic metal material. Was.

At this time, the heating plate (1) is subjected to a horizontal pushing force due to a rapid temperature rise. For this reason, in the case of a heated tableware formed by integral molding, there is no place for the force to escape, and the tableware is broken or broken.

[0009] In addition, if there is air in the pottery clay, the pottery explodes due to the thermal expansion of the air at the firing stage.

In order to solve this problem, it is necessary to provide a freely movable space (2) and a ventilation hole (4) to absorb the expansion energy.

[0011] In addition, the pottery cookware has a smooth and hard surface, and can be used with a cleanser or a metal spatula even when sticking, so that cooking can be performed with confidence.

[0012]

Embodiments of the present invention will be described below. (S) A saucer (3) molded of clay. (S) 1-3 mmφ at an arbitrary place on the bottom of the tray (3)
Through the vent hole (4). (C) Porcelain clay is made up of a mixture of water and various soils, and shrinks by about 10 to 20% at each stage of drying and firing.
A heating plate (2-3 mm thick) made of a magnetic metal material and made of iron, stainless steel, etc., having a melting point of 1300 ° C. or more while providing a space (2) in consideration of the above shrinkage inside the saucer (3). A heating section (5) in which 1) is inserted without fixing. (S) Homogeneous clay on the bonding surface (7b) of the heating unit (5)
The resulting glue (8) is applied and adhered to the main body adhesive surface (7a) on the bottom outside of the main body (6) molded of porcelain clay 700 to 800
Unglazed at ℃. (T) Decorate the heated tableware after unglazing, apply glaze, and bake at 1200 to 1300 ° C. The present invention has the above configuration.

When the present invention is used, a ceramic heating dish is placed on the top plate of a known electromagnetic cooker and the switch is turned on, so that the magnetic force lines generated from the magnetic force generating coil are connected to the heating plate (1). An eddy current is generated by the reaction, and the heating plate (1) generates heat. The heat is transmitted and heats the ceramic heating tableware.

At this time, a force is applied to the heat generating plate (1) so that the heat generating plate (1) expands in the horizontal direction due to a rapid rise in temperature. Also,
If there is a space (2) between the ceramic tableware and the heating plate (1), the air also thermally expands.

[0015] For this purpose, ceramic cookware and a heating plate (1)
When integrally molded or hermetically molded, the ceramic heating tableware and the heating plate (1) are broken or split by the force that can be spread in the horizontal direction due to a rapid temperature rise and the air thermal expansion. I will. Therefore,

(H) A ventilation hole (4) for allowing thermal expansion of the air to pass through was formed at an arbitrary position on the bottom of the tray (3) molded of clay. (T) A space (2) is provided between the saucer (3) molded of clay and the heating plate (1) to absorb the force of the heating plate (1) spreading horizontally due to a rapid temperature rise. .

[0017] The air thermal expansion of the space (2), which is generated when the ceramic heating tableware is heated by the above method, escapes through the ventilation hole (4), so that the air pressure of the space (2) is reduced. Disappears.

Further, the force that can be expanded in the horizontal direction due to the rapid rise in temperature of the heating plate (1) can be freely changed in the space (2), so that the energy due to expansion can be absorbed and the problem can be solved. Was done.

Further, there is a space (2) between the heating plate (1) and the main body (6), and this space (2) can serve to uniformize the heat distribution to the cookware.

Further, since the pottery is difficult to cool once it has heat, it is sandwiched between the saucer (3) and the heat of the main body (6), and the heat of the heating plate (1) and the space (2) is reduced. It was kept for a long time and helped keep warm.

The position of the air holes (4) can be applied not only to the bottom surface but also to the lateral surface, and the number of air holes (4) can be applied according to the situation.

The method of attaching the main body (6) and the heating section (5) can be applied in various ways, such as making the bonding surfaces of both surfaces different from each other, such as uneven or uneven surfaces so as to prevent the bonding displacement.

Further, by changing the thickness of the heating plate (1) and the thickness of the heated tableware, differences in the heating time and the cooling time can be applied to various cooking utensils such as cooked dishes, sukiyaki, and grilled meat.

If the heat-generating plate (1) is made of a perforated or wire-meshed material, it can be easily processed and reduced in weight.

Further, the heating section (5) can be applied in various ways such as a round type, a square type, a rectangular type and a donut type according to the cooking utensil.

Various materials such as glass, stone, and synthetic resin can be applied to the material of the heated tableware in addition to ceramics.

[0027]

According to the present invention, a general ceramic material can be used for an electromagnetic cooker by utilizing a general ceramic material, so that a conventional manufacturing method and a design decoration method can be used as it is. As a result, a wide range of technologies, such as traditional techniques cultivated over many years, can be applied to products.
