DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a lid opening and closing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a cooking vessel 1, for example a pot, is joined between an inner vessel 10 and an outer vessel 30, and between a inner vessel and an outer vessel. A heat-resistant handle 32 is mounted on the side surface of the outer container 30.

The inner vessel (10) is opened at its upper end and a space portion is formed therein. A seating part 11 is formed at the upper end of the inner container 10 to contact the bottom edge of the lid 40 with the cup 31. At least one through hole (12) is formed in the seating part (11). The inner container 10 is made of chrome and a nickel alloy, for example, stainless steel, and is excellent in heat resistance, corrosion resistance, and decorative property. Further, the inner container 10 preferably has a smaller coefficient of thermal expansion due to the applied heat.

The heat insulating member 20 is joined to the bottom surface of the inner container 10. The heat insulating member 20 is preferably made of a material having excellent heat conductivity and heat insulation. For example, aluminum or an aluminum alloy may be applied to the heat insulating member 20. Further, the thermal insulation member 20 preferably has a larger thermal expansion coefficient with respect to the applied heat.

The outer container 30 is opened at its upper end and a space portion is formed therein. Then, the insulating member 20 and the inner container 10 are integrally joined to each other inside the outer container 30. The outer container 30 is preferably made of chrome and a nickel alloy, for example, stainless steel, and is excellent in heat resistance, corrosion resistance and decorative property. Further, the outer container 30 should have a smaller coefficient of thermal expansion due to the applied heat.

3, the expansion member 21 is configured to extend from the edge of the insulating member 20 to the through-hole 12. [ A guide hole 22 is formed between the inner container 10 and the outer container 30 and connected to the through hole 12 formed in the seating part 11. The guide hole 22 is provided with an expansion member 21 Is inserted into the through hole (12) and is provided as a space in which the expanding member (21) is expanded and contracted. The expanding member 21 may be made of a different material or the same material as the insulating member 20. For example, the expansion member 21 is made of aluminum or an aluminum alloy. Further, the expansion member 21 preferably has a larger coefficient of thermal expansion due to the applied heat. Therefore, when heat is applied to the expanding member 21, the expanding member 21 is expanded and stretched, and the expanded member 21 is protruded from the through hole 12 along the guide hole 22. The heated expansion member 21 is contracted along the guide hole 22 while being cooled, and is positioned on a plane substantially parallel to the through hole 12. [ Furthermore, it is preferable that the expansion member 21 be manufactured so as to be located at the same position as the horizontal plane of the through hole 12 at room temperature when the cooking container 1 is manufactured. It is preferable that one to five guide holes 22 and the through holes 12 formed between the inner container 10 and the outer container 30 are formed. It is also preferable that the guide hole 22 is formed at the same temperature as the diameter of the expanding member 21 or larger than the diameter of the expanding member 21.

On the other hand, the expansion member 21 can be formed such that a certain space is formed between the outer circumferential surface of the inner container 10 and the inner circumferential surface of the outer container 30, and the expansion member 21 is joined to this space. That is, the expansion member 21 has substantially the same shape as that of the inner container 10 and the outer container 30, and exposes the end portion of the expansion member 21 through the through-hole 12.

The lid 40 is in a hemispherical shape and the edge bottom is brought into contact with the surface of the seating portion 11 of the inner container 10 to seal the space portion of the inner container 10. At least one receiving groove (41) is formed in the bottom edge of the lid (40). The receiving groove 41 is formed at a position corresponding to the through hole 12 formed in the seating part 11. [ Furthermore, when a plurality of through holes 12 are formed in the seating portion 11, the receiving grooves 41 are also formed at the same position.

7, the cooking container 1 is provided with a marking visible on at least one of the outer circumferential surface of the outer container 30 on which the through hole 12 is formed or the surface on which the receiving groove 41 formed on the bottom edge of the lid 40 is located. . This is because the first marking 43 engraved on the surface of the lid 40 is where the receiving groove 41 is located and the second marking 33 engraved on the outer circumferential surface of the outer container 30 is located where the through hole 12 is located, So that the user of the container 1 does not check the position of the receiving groove 41 by lifting the lid 40. Therefore, if the first mark 43 of the lid 40 and the second mark 33 of the outer container 30 do not coincide with each other, the cooking container 1 is heated and the expanding member 21 rises, So that the first mark 43 of the lid 40 and the second mark 33 of the outer container 30 coincide with each other so that the lid 40 is automatically opened by pushing up the bottom surface of the cooking container 1 The end of the expansion member 21 is inserted into the receiving groove 41 so that the lid 40 is not opened irrespective of the temperature rise of the cooking container 1 even if the expanding member 21 is heated. At this time, the diameter of the receiving groove 41 is formed to be larger than the diameter of the end of the expanding member 21, and the depth of the receiving groove 41 is set so that the expanding member 21 can sufficiently accommodate the extended length by thermal expansion. .

The operation of the lid opening / closing device of the cooking container according to the cooking temperature of the present invention will be described with reference to Figs. 4 to 6. Fig.

4, the positions where the receiving grooves 41 of the lid 40 and the through holes 12 of the outer container 30 do not coincide with each other, that is, the first marking 43 and the second marking 33 coincide with each other The cooking vessel 1 is placed on a heating source in a state where the cooking vessel 1 containing the food is placed at a position where the food is not placed and the heat is heated by the heating vessel 20 through the outer vessel 30 and the inner vessel 10) to warm the food contained in the inner container (10). At this time, aluminum which is excellent in thermal conductivity and warming property is preferably applied to the warming member 20 and the expansion member 21, and stainless steel which is an alloy of chromium and nickel is applied to the inner container 10 and the outer container 30 . The thermal expansion coefficient of the thermal insulating member 20 and the thermal expansion coefficient of the thermal expansion member 21 is larger than that of the inner container 10 and the outer container 30. While the cooking vessel 1 is being heated, the heat insulating member 20 is thermally expanded, that is, is linearly expanded. The expansion member 21 coupled with the heat insulating member 20 is also thermally expanded. For example, when the length of the heat insulating member 20 made of aluminum and the expansion member 21 is about 500 mm, and when heated at about 300 캜, stretching is performed by thermal expansion of about 3 mm or more.

5, the expansion member 21 is extended along the guide hole 22 and protrudes through the through hole 12 by the thermal expansion of the insulating member 20 and the thermal expansion of the expansion member 21. As shown in Fig. At this time, the bottom surface of the lid 40, which has been in contact with the surface of the seating portion 11 of the outer container 30, is raised by the projecting expanding member 21. When the lid 40 is heard, a space is formed between the outer container 30 and the lid 40 so that the pressure formed inside the cooking container 1 is reduced and the food is not boiled due to a decrease in pressure. Therefore, the expansion member 21 is further stretched in accordance with the temperature rise of the cooking container 1 to push up the lid 40, so that the food does not boil over.

When the cooking vessel 1 is gradually cooled after the cooking is completed, the expansion member 21 which has been stretched through the through hole 12 and the guide hole 22 is contracted. When the expanding member 21 is contracted, the edge of the lid 40 received from the cooking container 1 is lowered to be brought into contact with the seating part 11. [

Next, in Fig. 6, the lid 40 of the cooking utensil 1 is not automatically opened. This is a position where the receiving groove 41 of the lid 40 coincides with the through hole 12 of the outer container 30, that is, the position where the first marking 43 and the second marking 33 coincide with each other When the cooking vessel 1 is placed on the heating source while the cooking vessel 1 is covered and the bottom surface is heated, the heat is conducted to the warming member 20 and the inner vessel 10 via the outer vessel 30, (10). The first marking 43 and the second marking 33 may be applied with a temperature label whose color changes according to the temperature of the cooking container 1 and the lid 40, respectively.

The expansion member 21 is extended along the guide hole 22 and protrudes through the through hole 12 by the thermal expansion of the insulating member 20 and the thermal expansion of the expansion member 21. [ At this time, the end of the expansion member 21 is inserted into the receiving groove 41 formed at the bottom of the edge of the lid 40 which has been in contact with the surface of the seating portion 11 of the outer container 30, . When the cooking vessel 1 is gradually cooled after the cooking is completed, the expansion member 21 which has been stretched through the through hole 12 and the guide hole 22 is contracted. When the expansion member 21 is retracted, the end portion of the expansion member 21 inserted into the receiving groove 41 comes out of the receiving groove 41.

In the present invention, the thermal insulation member and the expansion member are made of a metal having a thermal expansion coefficient higher than that of the inner container and the outer container, but a gas or liquid having excellent expansion force can be applied or included by the applied heat.

As described above, according to the cooking temperature of the cooking lid of the present invention, the lid opening / closing device of the cooking container can automatically open the lid by heating the cooking lid according to the user's selection or can select the same function as the lid of the general cooking lid, There is an advantage that convenience for use is enhanced.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who has it will know it easily.

The present invention relates to a cooking apparatus and a method of manufacturing the same, and more particularly, to a cooking apparatus and a cooking apparatus having the same. home
