Description

Manufacturing method for induction stove and its article {manufacturing method for INDUCTION RANGE and cooker}

The present invention relates to a method for manufacturing pots for induction stoves and articles thereof, and more particularly to inserting a magnetic metal plate between aluminum plates to more efficiently use the magnetic force lines emitted from the induction stove. The present invention relates to a method for producing pots for induction stoves having high thermal conductivity and to articles thereof.

In general, a conventional kitchen container is made by joining aluminum to the bottom surface of the kitchen to increase the thermal conductivity from the heat source by the indirect heating gas stove, etc., by using a stainless steel material provided with rust prevention, but the corrosion of the aluminum As a measure to prevent damage, kitchen plates having a triple bottom or a five bottom structure, in which stainless steel plates are sequentially pressurized by a pressurizing device or joined by a high frequency heating method using a solvent such as powder or flux, are well known. .

However, such a kitchen vessel has been pointed out as a waste of stainless material and thus a cost increase, and there is a problem of power consumption because it can not efficiently use the magnetic lines emitted to the induction stove when using the induction stove.

Here, the induction stove is a cooking appliance that implements a direct heating method that generates heat by applying an efficient magnetic wire induction technology to generate magnetic force by generating magnetic force on the bottom of the bowl (container itself). It is a cooking utensil with higher safety, economy and convenience than indirect heating method (gas stove, other heating utensil).

As shown in FIG. 3, the heat transfer method by the induction stove generates magnetic force lines 5 in the solenoid device 4, and the magnetic force lines 5 are in contact with the upper ceramic plate 3. At the bottom of the panel, an electric current (2) is generated to generate heat. Here, the basic operation principle is to cook food by the heat generated by the magnetic force line 5. The induction stove selects an appropriate temperature in the temperature sensor 6, generates heat by magnetic induction, and cooks food.

Therefore, in order to generate an eddy current at the bottom of the kitchen utensil, a container such as aluminum material having a relatively high thermal conductivity used in the indirect heating method cannot pass magnetic lines emitted from an induction stove due to the physical properties of aluminum. Therefore, there is a problem that can not be used in induction stove with the same type of aluminum material only.

Therefore, the conventional kitchen container used for the induction stove is a bottom surface of the stainless steel bottom exposed to the lower portion of the ordinary container on a simple plane of the same material, the magnetic force of the induction stove in contact with the bottom surface is made of the same material or stainless steel And a planar bottom surface of a dissimilar material such as aluminum.

In addition, since the conventional kitchen containers continue to be heated depending on the magnetic force of the induction stove, they not only cause significant waste of heat and loss of combustion heat, but also in the case of a container made of a material such as stainless steel, which is partially pressed or burned out. There is a problem.

The present invention has been invented to solve the above problems, by inserting a magnetic metal plate between the aluminum plate to more efficiently use the magnetic force lines emitted from the induction stove to enable induction cooking and thermal conductivity To provide a high and beautiful method for manufacturing pots for induction stove and its object, there is a purpose.

The above object is achieved by inserting a magnetic metal magnetically in part or all of the flooring material of the aluminum pots in order to use the pots of which the flooring material of the induction stove that emits magnetic lines is made of aluminum according to the present invention. .
