Abstract

PROBLEM TO BE SOLVED: To eliminate the generation of failure by a beginner and, furthermore, a skillful person so as to safely make a fryed egg by forming an egg frying par for electromagnetic cooker a magnetic metal material having a Curie temperature in a specified temperature range and a non-magnetic metal material. SOLUTION: A side of an egg frying pan 1 for a material to be cooked is made of cooper 1a as a non-magnetic metal, material, and a plating layer 1b of tin is formed in a surface thereof. A magnetic metal material 1c, which is formed of temperature sensitive stainless steel having a Curie temperature at 140-180 deg.C, is connected to a top-plate 3 side of the egg frying pan 1. A heating coil 2 is built in an electromagnetic cooker. Since this egg frying pan is operated by the maximum output till the temperature achieves the set temperature, rising time (pre-heating time) can be shortened, and since the egg frying pan is not heated to a temperature more than the set temperature, generation of burning of the material to be cooked can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg fryer used in an electromagnetic cooker.

[0002]

2. Description of the Related Art Conventionally, when cooking fried eggs using an electromagnetic cooker, a method has been adopted in which an fried egg made of iron or stainless steel is used and cooking is performed under optimum set temperature conditions.

[0003]

However, in the electromagnetic cooker, the temperature of the egg-burning machine is controlled by the thermistor installed on the back surface of the top plate. It was difficult to determine the accuracy of the heating set temperature. In particular, in the case where the warp at the bottom of the pot of the fried egg cooker used was large, the above tendency was more remarkably observed, and it became more difficult.

[0004] Since the heating temperature is not stable in this way, especially for beginners and experienced persons, when they cook for the first time with an electromagnetic cooker or when they purchase a new fried egg cooker, they often burn the fried egg. There was a problem.

[0005] It is an object of the present invention to provide an egg cooker for an electromagnetic cooker, which can be used for beginners as well as skilled workers to safely fry eggs without failure.

[0006]

In order to achieve the above-mentioned object, the present invention provides an egg cooker for an electromagnetic cooker, which has a temperature of 140.degree.
It is composed of a magnetic metal material having a Curie temperature of 80 ° C. and a non-magnetic metal material.

Further, a temperature-sensitive stainless steel is used as a magnetic metal material, and copper is used as a non-magnetic metal material.

[0008]

DETAILED DESCRIPTION OF THE INVENTION
A magnetic metal material made of a temperature-sensitive stainless steel having a Curie temperature and a non-magnetic metal material made of a non-magnetic metal material with an excellent heat conductor such as copper. Because there is no
It has the effect of preventing the scorching of the fried egg and stabilizing the quality of the fried egg.

By the way, an egg fryer used in a cooker other than the electromagnetic cooker is generally made of copper having good heat conductivity, and has an inner surface plated with tin. Therefore, basically, copper cannot be used as a pan for an electromagnetic cooker. However, by joining the magnetic metal material to the bottom surface as described above, it can be used for an electromagnetic cooker. In addition, since a temperature-sensitive stainless steel having a Curie temperature is used as the magnetic metal material, the heating temperature does not rise above the set temperature, and the tin plating (melting point: 232 ° C.) applied to copper is almost deteriorated. do not do. Furthermore, since it has excellent corrosion resistance, it does not rust. On the other hand, the use of copper as the non-magnetic metal material has excellent thermal conductivity, stabilizes the workmanship of cooking, and has the effect of making it relatively easy to join the copper and the temperature-sensitive stainless steel in contact.

[0010]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a state in which an egg cooker for an electromagnetic cooker (hereinafter, egg cooker) is placed on a top plate. In the figure, reference numeral 1 denotes an egg fryer, and reference numeral 2 denotes a heating coil built in an electromagnetic cooker. Reference numeral 3 denotes a top plate installed above the electromagnetic cooker.

The cooking side of the fried egg cooker 1 is made of copper 1a, and a plating layer 1b of tin is provided on the surface thereof. A magnetic metal material 1c made of temperature-sensitive stainless steel having a predetermined Curie temperature is joined to the top plate 3 side.

Here, the Curie temperature is from 100 ° C. to 20 ° C.
Each egg fryer was prepared by using one changed in the range of 0 ° C. Egg fry cooking was evaluated using this egg fryer. For the fried egg cooking, an electromagnetic cooker was used to cook the food ten times in a row, and the situation where the fried egg was scorched and the condition of fire were examined. The results are shown in Table 1.

As shown in Table 1, the Curie temperature is 140 ° C.
In the fried egg cooker described below, although no scorch occurred, the fire was poor and was not a favorable result. On the other hand, at 180 ° C. or higher, burning was good, but burning occurred, and a problem was observed.

However, the temperature of 140 ° C. to 180 °
In the case of ° C., there was no problem in both burning and burning, and a favorable result was obtained.

[0015]

[Table 1]

The Curie temperature is 160 for reference.
The change in the temperature of the egg fryer in ° C. will be described with reference to the graph of FIG.

When the heating of the fried egg is started at the timing a, the heating is performed with the maximum power until the Curie temperature of 160 ° C. is reached (b). After reaching the Curie temperature, the output of induction heating decreases, and the temperature of the fried egg is kept at 160 ° C. When the egg solution is added at the timing of c, the temperature of the fried egg falls, but the heat automatically rises and rises toward the Curie temperature. This egg liquid is coagulated by heat and wound around one side of the fried egg cooker, and then re-injected into the egg liquid (d). Try to keep the vessel temperature as constant as possible.

From this, a cook can produce a stable and well-made fried egg without manipulating the heat setting of the electromagnetic cooker.

[0019]

As described above, according to the present invention, the following effects can be obtained.

(1) Since heating is performed at the maximum output until the set temperature is reached, the rise time (preheating time) can be minimized.

(2) Since the food is not heated to a temperature higher than the set temperature, it is possible to prevent the food from being excessively scorched.

(3) In response to a decrease in the temperature of the fried egg cooker when the egg liquid is supplied, the maximum heating is automatically performed until the temperature reaches the set temperature.
Since the temperature accuracy with respect to the set temperature is extremely good, stable workmanship can be obtained.

(4) If this fried egg cooker is used, even when cooking with a different electromagnetic cooker, the temperature of the fried egg cooker at the time of heating is stabilized, so that the same quality can be obtained.
