The present invention relates to a pressure cooker for an induction stove.

In general, a pressure cooker (pressure pot) refers to a device that cooks food that is hard to be cooked at normal pressure in a short time by increasing the pressure in the cooker by sealing, and the bones of tough meat and fish become soft. Bean rice or brown rice can also be cooked easily. It is made of thick material of stainless steel or aluminum, and rigidly engaged or screwed to close the lid, and the lid is equipped with a safety valve. When the safety valve is over a certain pressure, the valve is automatically opened to release steam to maintain safety, but an auxiliary safety valve is also attached to increase safety. Some pressure gauges are also attached.

As such, the pressure cooker is heated in an airtight state to display rice or various dishes using high pressure, and the internal pressure is high, so care must be taken in handling the heat source, such as a gas fire or an electric plate. Heating in the manner of use may cause injuries caused by the user due to careless handling.

Thus, an induction range has a built-in coil for generating a magnetic field when a high voltage is applied to the induction range, and such an induction range induces a magnetic field when a high voltage is applied to the coil. There is no risk of fire because no flame or harmful gas is generated by heating only the container by heating by magnetic field. There is no occurrence, the consumption of indoor oxygen is low, there is a feature that can maintain a comfortable room.

Induction stoves do not cause burns even when the grille is touched while the container is heated.There is no spark, so there is no risk of fire or explosion, and the body does not burn even when the grille is touched while the power is on. It has been used a lot recently.

However, a container for use in such an induction stove must be made of metal with the bottom surface of the container, which is the part touching the grille, to be magnetically induced by the magnetic field generated by the induction stove. That is, the bottom surface of the cooking vessel should contain iron (Fe).

Therefore, as the induction stove can be used only a container made of a magnetic material and magnetic sensitization, a container made of a non-ferrous metal such as aluminum or stainless steel or a container made of stoneware and porcelain, which occupies most of the pressure cooker. This is an impossible drawback.

Thus, the metal plate is attached to the bottom surface of the container body of the non-ferrous metal for use in the induction stove, the container that can be used in the induction stove is made of a non-ferrous metal and a different material of the metal material.

However, although the outer layer member made of a conductive material is made of an iron-based metal so that an induced current can be generated in an electric field generated in the coil to the outside of the inner layer member made of a non-ferrous metal having excellent heat transfer and light weight, the thermal conductivity of the iron-based metal is The heat generated in the eddy current caused by the induced current is significantly reduced and the heat loss is poor in the outer layer member, which causes a problem of heat loss.

In addition, the conventional pressure cooker has a problem in that it is difficult to handle because the weight of the pot is formed by forming the outer layer member of the stainless steel based on the outside.

In addition, the conventional pressure cooker requires expensive rolling equipment for crimping dissimilar metals to form dissimilar members with non-ferrous metals and ferrous metals, which requires installation space and cost, and strain rate during compression molding of the dissimilar members. Since the difference occurs, in order to minimize the strain, it is necessary to compress slowly so that the working time is increased and the manufacturing cost is increased.

Therefore, in recent years, in order to improve the thermal conductivity, a plating layer for plating brass and gold having excellent thermal conductivity was formed on the outside, but since the thermal conductivity of the iron-based metal is very low, even when plating brass and gold having excellent thermal conductivity to the outside, There is a problem that the thickness is too thin, the effect of improving the efficiency of thermal energy is weak, the corrosion resistance is strong, difficult to brass or gold plating work, the process is increased, the productivity is reduced.

In addition, the pressure cooker is used for the electromagnetic induction heating is limited to the coil heating portion, whereas the outer layer member having an outer coating layer for improving the thermal conductivity used for electromagnetic induction is used more than necessary, There is a problem that is increased, the production cost due to processing is increased.

In addition, the stainless steel member formed of the outer layer member is excellent in corrosion resistance, but the ferrite structure and permeability, which are essential elements of the induction heating device, are significantly lower than those of the general metal, resulting in the generation of the eddy current of the electromagnetic induction method. There was a problem that the thermal efficiency is lowered.

In addition, the pressure cooker has a problem that it is difficult to uniformly manage the internal temperature as the amount of the contents during cooking of food as the whole portion of the cooker is heated.

In order to solve the above problems, the main object of the present invention is to provide a closed portion of the pot with a pressurized airtight seal formed on the upper portion of the aluminum single member, and the corrosion is prevented by a corrosion prevention layer of the coil heating portion of the induction stove which is induced to the lower side. The ferrite structure with the anti-corrosion layer to be prevented and the magnetic layer of low-carbon steel with excellent permeability are welded to the adhesive layer to reduce the manufacturing cost and improve the productivity with a single member, and to increase the thermal efficiency by improving the electron induction efficiency.

As such, the pressure cooker for induction stove of the present invention devised to achieve the object is a pressure cooker used in the induction stove for heating with an electromagnetic induction, the pressure cooker is a pressure-sealing unit provided with a closed coupling to the lower side to seal the pressure at the top. And a pressurizing part which forms a sealing handle on both sides of the pressurizing airtight seal, forms a pressurizing packing to prevent leakage of pressure on the upper part of the airtight sealing part, and forms a pressure nozzle to adjust the pressing force to the center of the pressurizing airtight opening. Handles are formed on both sides of the upper portion of the pot vessel having a pressure coupling portion at the upper portion to be coupled to the lower portion of the pressing portion, and the pot vessel is formed of a single aluminum-based member, and an inner stone layer having a stone shape inside the vessel vessel. Forming a lower heating portion at the coil heating portion contact portion of the induction stove at the lower portion of the pot vessel, A corrosion-resistant layer coated with aluminum or zinc is formed to spray the magnetic layer of a low carbon steel material having excellent permeability and permeability by melting and spraying an adhesive layer made of nium wire, aluminum bronze and nickel with electric arc. Formed

In addition, the pot portion is characterized in that it is configured to further include a thermal conductive layer to improve the thermal conductivity and thermal conductivity by applying pure silver to the outside of the magnetic layer.

In addition, the lower portion of the pot portion is provided with a heating groove in the form of a groove in the lower heating portion formed in the contact portion of the coil heating portion is characterized in that it is configured to melt by bonding the adhesive layer to form a magnetic layer inside the heating groove.
