Description

Cookware for induction hobs

technical field

The present invention relates to a cooking container for an induction cooker, more particularly to a cooking container for an induction cooker in which a ceramic container or a glass container is combined with a metal container.

Background technique

Recently, the technological development of induction cookers using induction heating technology is actively progressing, and the market for induction heating cookers with cutting-edge technology has also expanded and widely used.

Induction heating (IH, Induction Heating) refers to a technique of applying electricity without directly contacting an object to be heated. That is, when a coil (wound copper wire, etc.) is energized, magnetic flux lines are formed in the space adjacent to the coil, and a container of a material capable of absorbing magnets is placed in the magnetic flux space, and directly heated to generate heat.

The induction cooker using the above induction heating not only has no pollutants such as sparks or smoke, but also directly heats the container that can absorb the magnet, so the risk of fire and burns is small. It is used in apartment hotels, hotel rooms, offices in office buildings, single room users, Large-scale commercial use of restaurants in buildings, etc., is gradually replacing the existing cookers using city gas.

However, in order for the cooking container used in such an induction cooker to generate magnetic induction according to the magnetic field generated in the induction cooker, the bottom surface of the container that is in contact with the grill portion needs to be made of metal. That is, the bottom surface of the cooking container needs to contain iron (Fe) components.

Therefore, the induction cooker can only use cooking containers made of metal materials that can be magnetically induced to a magnetic field. It is not allowed to use containers made of non-ferrous metals such as aluminum or stainless steel that account for most of the cooking container, or containers made of stoneware, ceramics, glass, etc. Therefore, the bottom surface of the non-ferrous metal cooking container of the part that is in contact with the coil plate of the induction cooker is sometimes attached with a ferrous metal plate of a magnetic body.

Therefore, the variety of materials and shapes of the cooking container for an induction cooker are limited, and the manufacturing process is complicated to increase the cost.

The cooking container 100 for an induction cooker according to an embodiment of the present invention is formed by inserting a metal inner plate 120 into a ceramic container or a glass container 110 .

Here, the ceramic container or glass container 110 is in the same shape as a common container and has a concave shape that can accommodate food. At this time, the inside of the ceramic container or glass container 110 may have a shape that is gradually concave like a plate, or may have a shape of a pot with a deep bottom.

The inner surface of the ceramic container or glass container 110 is protrudingly formed with a locking end 130 having a specified width and width. Preferably, the locking end is 35 mm to 50 mm above the bottom surface of the ceramic container or glass container 110. Internal faces are formed. This is because the height through which the magnetic field induction heating can pass through the upper plate of the induction cooker 200 located at the lower part of the ceramic container or glass container 110 is 35 mm to 65 mm, so the height between these is the most suitable.

Here, the locking end 130 is protrudingly formed in a strip shape over the entire inner surface of the ceramic container or the glass container 110, and may be waved and circular at predetermined intervals.

In addition, the upper surface of the locking end 130 may be gradually inclined downward from the outside to the inside.
