Description

Pot of double structure {Air-core Pan}

The present invention relates to a dual-pot pan that allows for good heat preservation during cooking.

In order to prevent heat damage and improve the taste of food by uniformly conducting heat during cooking, a double-pot has been proposed.

The idea of such a pot structure is 10 October 10, 1985. It is disclosed in the published Utility Model Publication No. 85-7307, which proposes a structure in which a paraffin is melt-filled in a double structure space and an air fin is installed at the circumferential edge.

In addition, Japanese Laid-Open Patent Publication No. 56-169825, published on December 15, 1981, discloses a double-pot and a pot (heating container) in which operating fluid is injected into the double-walled void.

In addition, the structure of filling and sealing the heat medium oil instead of the paraffin was disclosed in Utility Model Publication No. 97-4035 published on April 25, 1997.

The conventional dual structure pot is an idea that the heat medium is filled in the gap of the dual structure to have an even distribution and heat retention of heat transfer, but the heat medium material should be filled after the double structure is made and sealed to prevent leakage. There were difficulties in manufacturing and there were problems that harmed the cooked food when the heat medium leaked out.

Accordingly, an object of the present invention is to provide a heating vessel (eg, a pan) having a dual structure having a uniform heat distribution and good heat preservation, which is devised to solve the problems of the conventional apparatus described above.

The present heating container (hereinafter referred to as a "pot") is a double-shaped pan having a space in which the outer shell and the inner shell are spaced from the side, the first being inserted between the lower bottom surface of the inner shell and the inner bottom surface of the outer shell. A heat transfer plate, a second heat transfer plate attached to the bottom bottom surface of the outer shell, a reinforcement plate attached to the lower surface of the second heat transfer plate, and having an edge portion joined to the outer shell of the pot while surrounding the second heat transfer plate, It includes a rhombus made by rolling the outer surface of the pan and the inner edge of the pan so that the lateral space is completely sealed including air, a pot lid covering the pot body, and a heat insulating cover covering the odor lid with a certain space at the top. The pot lid is made of tempered glass disc with stainless steel ring attached to the edge, and the insulation cover is stainless steel dome cover. desirable.

Hereinafter, specific embodiments of the present invention will be described with reference to FIG.

Pot of the present invention is a cooking utensil made to cover the lid 20 and the insulating cover 30 to the pot body 10 to be used.

Lid 20 is a hole in the center of the domed disc 21 made of Tempered Glass (21) attached to the handle or ring 23, and surrounded by the bowlight frame 22 made of stainless steel around the disc . Insulating cover 30 is made of a stainless steel plate 31 in a dome shape, the handle 32 is attached to the center. Therefore, when the pot is not required to keep the pot contents warm, only the pot lid 20 made of tempered glass is used. By covering the heat insulating cover 30 on the top to form an air layer between the pot lid 20 and the heat insulating cover 30 to prevent heat emitted to the top of the pot to keep warm. And, the pot lid 20 is preferably prevented from being damaged by the attachment of the beam of the stainless steel ring to the edge.

The pot body 10 is formed by the end of the outer shell (1) and the inner shell (Inner shell: 2) to form a space (air layer: 6) by rolling the end of the shell and the endothelial (7). In the lower part of the space 6, a first heat transfer plate 4 made of aluminum is provided between the outer shell 1 of the pot and the inner shell 2 so that the bottom inner surface of the outer shell 1 and the bottom lower surface of the inner shell 2 are provided. The second heat transfer plate 5 made of aluminum is bonded to the outer lower surface of the outer shell 1, and is joined to the lower surface of the second heat transfer plate, thereby being completely connected to the side surface of the second heat transfer plate. The reinforcement board which is joined to the outer shell 1 while enclosing easily is provided.

It is more preferable if the pot shell 1, the inner shell 2 and the reinforcing plate 3 are made of stainless steel plates, and the first heat cutting plate 4 and the second heat transfer plate 5 are made of aluminum plates.

When a heat source is supplied to the lower part of the pot having such a structure, the heat transferred to the reinforcement plate 3 is transferred to the second heat transfer plate 5, which is an aluminum plate, and then the outer shell 1-> first heat transfer plate 4. )-> Endothelial (2) is delivered to heat the contents contained in the endothelial (2).

Most of the heat applied by the heat source (not shown) at the bottom of the pot has an uneven heat distribution. When such non-uniform heat is applied to the reinforcing plate 3, heat is dispersed by heat conduction, and when the heat reaches the aluminum plate, which is the second heat transfer plate 5, it is further dispersed and transferred to the bottom of the shell. Most of the heat transferred to the bottom of the shell is conducted to the first heat transfer plate 4 to the inner skin, and part of the heat is conducted to the side of the shell to heat the air layer 6 and to the air layer 6. Is delivered to the endothelium and can heat the contents inside the pan in contact with the sides of the pan. The heat transmitted through the various layers is distributed evenly so that the heat distribution of the endothelium is more even than that of the heat source. The air layer 6 contains air which is naturally present during operation without filling a special heat medium. The air layer 6 allows heat to be transferred to the side of the pot from the bottom of the pot during cooking. In addition, the contents of the pot should be heated and cooked on the side other than the bottom of the pot. And, after cooking serves to delay the heat transfer between the endothelial (2) and the outer shell (1) of the side of the pot also serves to keep warm.

The evenly distributed endothelial heat evenly heats the contents contained in the pot, and the heated contents are not easily cooled through the side even if the heat source in the lower part is weak or disappeared, and the heat is preserved for a long time.

In addition, the lid 20 and the insulating cover 30 also prevents the heat released to the top of the pot to facilitate the heat preservation inside the pot.

The pot of the present invention heats the food evenly, so that only a portion of the food is burned or heated too much to prevent the food from spoiling, and the heat is well preserved to improve the taste of the food. And the thermal efficiency of the pot is also good.
