In the present invention, the cooking vessel used in the induction range can be manufactured and used in various material, and an inexpensive vessel can be provided by manufacturing in a simple process, and the present invention has an advantageous point in that energy efficiency is high and there is no danger of burns as radiant heat, which is generated outside of the cooking vessel as the cooking vessel is heated, is low.

Description

Cooking container for induction stove

The present invention relates to a cooking container for induction stove, and more particularly, to an induction stove cooking container in which a metal container is combined inside a container of porcelain and glass.

Recently, the development of induction stove using induction heating technology (誘導加熱技術) has been actively developed, and the interest in the high-tech induction heating cooker market has been widely used.

Induction Heating (IH) is a technology that allows an induction current to flow without directly contacting an object to be heated. In other words, when electricity is supplied to a coil (a coil wound on a copper wire), a magnetic force line is formed in a space near the coil, and a magnetic container is placed in the magnetic force line space, and heat is generated by direct heating.

Induction stoves are free from flames and smoke, and also directly heat only containers that can hold magnets, thus reducing the risk of fire and burns. Condo, hotel rooms, offices in office buildings, studio furniture, large-scale commercial It is being used by gradually replacing the cooker using the existing city gas mainly on restaurants in buildings.

However, cooking vessels for use in such induction stoves must be made of metal with the bottom surface of the vessel, which is the part touching the grille, in order 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, the induction stove can be used only cooking containers made of magnetic materials and magnetic sensitization, and made of non-ferrous metals such as aluminum or stainless steel, stoneware, porcelain, glass, etc., which occupy most of the cooking containers. Since the container is not usable, a ferrous metal plate of magnetic material may be attached to the bottom surface of the non-ferrous metal cooking vessel at the portion in contact with the grill of the induction stove.

Therefore, the induction stove cooking container has a limitation in the variety and form of the material, and the manufacturing process is also complicated, there was a problem such as a rise in cost.

First, there is no particular limitation on the shape and structure of the induction stove applied to the present invention, such as an induction stove fixed to a table, a movable induction stove, and an induction stove installed below the table. Say.

Induction stove cooking container 100 according to an embodiment of the present invention is made of a metal inner plate 120 is inserted into the interior of the magnetic or glass container 110.

Here, the magnetic or glass container 110 is formed in a concave shape to accommodate food as in a general container. At this time, the inside of the magnetic or glass container 110 may form a gently concave shape in the form of a plate, it will be obvious that the bottom may be formed deep in the form of a pot.

On the inner surface of the magnetic or glass container 110, the locking end 130 is formed to protrude with a predetermined width and width, preferably formed at a height between 35 mm and 50 mm from the bottom of the magnetic or glass container 110. It is preferable that the height between them is 35 mm to 65 mm in height that allows magnetic field induction heating transmission from the top plate of the induction stove 200 positioned below the magnetic or glass container 110.

In this case, the locking end 130 may be formed to protrude in the form of a strip on the entire inner surface of the magnetic or glass container 110, and may be formed in a circular shape at a predetermined interval in a waveform form.

In addition, the locking end 130 may be inclined so that the upper surface is lowered in the lower direction toward the inner side from the outer side.

In addition, the support end 140 may be bent in a horizontal form in the outer direction on the upper edge of the magnetic or glass container 110.

Herein, the metal inner plate 120 is inserted into the magnetic or glass container 110 and mounted on the upper surface of the locking end 130 protruding from the inner surface of the magnetic or glass container 110.

In this case, the recess 121 may be formed in the center of the metal inner plate 120 to be concave downward. This is to narrow the distance from the lower induction stove 200 top plate.

In addition, a plurality of water passages 122 may be formed at predetermined intervals in the middle portion and the edge of the metal inner plate body 120. This is to allow oil or the like flowing down from the central side of the inner metal plate body 120 to be discharged to the magnetic or glass container 110.

On the other hand, in the case of a container such as a pot deep in the bottom of the magnetic or glass container 110, it is preferable to fill the water so that the metal inner plate 120 mounted on the locking end 130 is submerged in water. In this case, it will be possible to provide a separate lid 140.

Cooking vessel 100 for cooking food on the cooking vessel 100 of the induction stove of the present invention configured as described above, in order to use as a fire plate for roasting meat, the bottom is shallow and wide plate-shaped porcelain or glass The container 110 may be used, and for cooking, such as boiling or boiling food, the container 110 may use a porcelain or glass container 110 having a deep bottom and a narrow width.

A metal inner plate 120 is inserted into the magnetic or glass container 110 so as to be mounted on an upper surface of the locking end 130. Therefore, the metal inner plate 120 is spaced apart from the bottom surface of the magnetic or glass container 110 at predetermined intervals.

Then, the bottom of the porcelain or glass container 110 is filled with water to a predetermined height, the bottom of the porcelain or glass container 110 is filled with water to a lower height than the metal inner plate 120, the bottom deep porcelain Alternatively, the glass container 110 is filled with water such that the metal inner plate 120 is wound.

When the magnetic field is generated through the top plate by operating the induction stove 200 on which the cooking vessel 100 is placed, the metal inner plate 120 coupled to the inside of the magnetic or glass container 110 is heated to generate heat. do.

At this time, the magnetic container or the glass container 110, which is an external container while the food is cooked, is not directly heated, but the inner metal inner plate 120 is heated to a temperature at which cooking is possible, and thus, the cooking container 100 of the present invention. Touching will reduce the risk of burns and other injuries.

Table 1 below is a value obtained by measuring the temperature and power of the magnetic or glass container 110 after a predetermined time has passed since the induction stove 200 is operated. Before operating the induction stove 200, the temperature of the metal inner plate 120 coupled to the inside of the magnetic or glass container 110 was 21.5 ° C.

Therefore, foods such as meat may be placed on the metal inner plate 120 coupled to the inside of the porcelain or glass container 110 having a shallow bottom and a wide dish, and cooking may be performed. The porcelain or glass container 110 heated by induction heating is heated and cooked by raising meat, etc. At this time, the oil generated while heating flows down to the edge of the porcelain or glass container 110 while passing through the water port 122. Through the magnetic or glass container 110 bottom. When the oil flowing down is lowered inclined downward in the downward direction it is easily flowed into the interior of the magnetic or glass container 110.

In addition, water vapor generated while the water filled in the magnetic or glass container 110 is heated prevents the meat from being hardened as it is baked. In addition, the cooked meat, etc. may be placed on the upper support end 140 of the magnetic or glass container 110 to prevent further heating.

Meanwhile, as the metal inner plate 120 coupled to the inside of the porcelain or glass container 110 having a deep bottom and a narrow pot is heated by induction heating, the food material placed on the upper surface of the porcelain or glass container 110 is cooked. Will be.
