Description

[0001] The present invention relates to an induction cooking apparatus,

The present invention relates to an induction range in which the convenience of cooking is improved, and more particularly, to an induction range in which the induction heating principle is applied to perform various kinds of cooking, Heat-resistant synthetic resin (ie, thermoplastic resin PBT, PPS, or PET series) based on a high-heat-resistant composite polymer that is not a tempered glass or melamine resin being used and having a heat-dissipating function by mixing a heat- It is possible to reduce the production cost of the top plate and the product itself, minimize the scratches on the surface during use, and reduce the heat loss It is possible to reduce the noise caused by the fan, To the invention to be able to.

Generally, an induction cooker or an induction range, which is an induction heating cooker, generates magnetic lines of force when a high frequency current is applied to a working coil, generates a large number of eddy currents at the center of the magnetic force lines, Is heated by induction heating so that various kinds of food contained in the container or the heating plate are heated and cooked by heating the cooking vessel or the heated plate by induction heating.

Such an induction range has no danger of fire because it does not generate flame or harmful gas due to incomplete combustion, and it does not generate carbon monoxide which is inevitably generated when gas is used as a heat source, There is a maintainable feature.

Such an induction range has recently been used in many cases because it has no fear of burning even if the grill touches the hand while heating the container and there is no risk of fire and explosion because there is no flame.

Meanwhile, most of the conventional induction range top plates are formed by attaching heat-resistant tempered glass to the upper surface of the upper cover which is formed by injection molding in the form of a rectangular frame. When the upper plate is provided with heat-resistant tempered glass, However, after the heat-resistant tempered glass having a predetermined thickness is cut to a desired area, it is necessary to perform post-processing such as curving processing for the corner portion, thereby increasing the labor cost and the manufacturing cost, causing many scratches on the surface of the glass during long- Since there is no separate anti-slip function, when the container slides on the top plate during cooking and there is soup or water on the top surface, the bottom surface of the container having the flat shape is attached due to the surface tension, In the process of forcibly lifting the container, Is liable to cause an accident, there are also issues short life of the roof than the various components installed in the body.

In addition, there is a risk that the heat generated in the container being cooked is conducted to the heat-resistant tempered glass and the heat is transmitted to the components located in the lower portion of the upper plate in the main body. To prevent this, To increase the amount of heat dissipation, thereby causing unnecessary fan noise.

In some cases, melamine resin, which is a thermosetting resin which is formed by reacting melamine with formaldehyde as a top plate of a conventional induction range, is integrally formed with the top cover. This melamine resin is strong against heat, acids and solvents, It is not only expensive but also less expensive than heat-resistant tempered glass. However, it has problems such as discoloration or fading due to curing due to high temperature during long use, Problems such as a short life span, a slip of the container, a noise of a fan, and the like, which are inherent in the heat-resistant tempered glass, and furthermore, environmental hormones are generated at the time of heating or disposal.

There is also a configuration in which a ceramic upper plate having a shape obtained by processing and molding a base metal or an inorganic material at a high temperature with a top plate of a certain induction range is fixedly mounted on the upper surface of the upper cover having a rectangular frame shape. The heat resistance and abrasion resistance are superior to those of the above two materials. However, the cost of the raw material itself is high as well as the cost of processing and molding, and thus the cost of the product itself is greatly increased. (For example, the container slips and the fan noise is generated).
