In the present invention, the pot is constituted of a pot and a pot, and functions to cook the food and to heat the cooked food. In addition, the dual pan is combined with a double lid made up of a multi-layered structure to facilitate quick cooking and extension of the keeping time.

In FIG. 1, the double pan 1 has a structure in which the inner pan 20 is inserted and stacked in the outer pot 10, so that the double lid 30 can be closed.

2 and 3, the surface pot 10 is formed with an open top and a space portion capable of receiving the inner pan 20 therein. Guide protrusions 11, which are inclined at a predetermined angle, protrude inward from the inner circumferential surface of the outer surface of the outer surface of the outer pot 10. [ It is preferable that the guide projection 11 is protruded from the inner surface of the outer pot 10 at least once at a predetermined slope. A pair of knobs 12 are engaged with each other at a position facing the outer circumferential surface of the outer surface of the outer pot 10. [

The inner pot 20 has a top portion thereof opened and a space portion for containing water to be cooked or food ingredients therein. And an engaging portion 21 protrudes outwardly from the inner pot 20. The engaging portion 21 is bent at the upper end to the outer lower portion and extended to the lower portion by a predetermined length, and then bent to the upper inner portion to be fixedly coupled to the outer side wall. A space portion is formed between the engaging portions 21. A sliding protrusion 22, which is inclined at a predetermined angle, protrudes outward from the upper surface of the outer circumferential surface of the engaging portion 21. A seating portion 23 is formed so that the lid 30 can be placed on the inside of the upper portion of the engaging portion 21.

The sliding protrusion 22 is screwed to the guide protrusion 11 protruding from the inner circumferential surface of the pot 10. [ In other words, the mountains and the valleys of the sliding protrusions 22 are in contact with the valleys and mountains of the guide protrusions 11, respectively, so as to be rotated. Furthermore, it is preferable that the sliding protrusions 22 are protruded from the outer peripheral surface of the inner pot 20 at least once at a predetermined slope.

The surface of the guide protrusion 11 and the surface of the sliding protrusion 22 are coated with fluorine which is resistant to scratching. However, a material having a frictional force and a high sealing force may be coated between the guide protrusion 11 and the sliding protrusion 22, It might be. A pair of knobs (24) are engaged with each other at a position facing the outer circumferential surface of the upper part (21) of the fastening pot (20). It is also preferable that the surface pot 10 has a height larger than the height of the inner pot 20 by being rotated inside the surface pot 10 by rotation. Therefore, a step is formed between the top pot 10 and the top end of the bottom pot 20.

In addition, space portions are formed between the inside of the outer pot 10 and the outside of the inner pot 20, and the air filled in the space makes the insulation between the outer pot 10 and the inner pot 20. The gap between the outer pot 10 and the inner pot 20 is determined depending on the width of the engaging portion 21 but may vary depending on the protrusion and contact distance of the guide protrusion 11 and the sliding protrusion 22. [ 5, the heat-resistant insulating material 40 may be filled in the space portion between the outer pot 10 and the inner pot 20 and the engaging portion 21.

6, the bottom of the surface pot 10 is formed with a plurality of concentric concave and convex portions 13 in a radial direction at the center thereof, and the bottom surface of the inner pot 20 contacting the floor of the surface pot 10 is also radially concentric, It is preferable that a plurality of recesses 25 are formed to increase the contact area between the bottom of the outer pot 10 and the bottom of the inner pot 20. [ This makes it possible to easily transfer the heat applied to the surface pot 10 to the bottom surface of the inner pot 20.

Next, in FIG. 4, the double lid 30 is seated on the seating part 23 formed at the upper end of the inner pot 20 so as to be covered. The double lid 30 is composed of a multi-layered structure, and a hemispherical upper plate 31 and a hemispherical lower plate 32, which are connected to each other with a space at a certain interval below the upper plate, are integrally joined. The upper plate 31 and the lower plate 32 may be made of metal, glass, enamel, or the like. Furthermore, the upper plate 31 and the lower plate 32 can be integrated by joining a rim 33 made of metal or silicon in a ring shape at the edges of the upper plate 31 and the lower plate 32. The handle 34 is engaged through the upper center portion of the upper plate 31 and the lower plate 32. [ An air layer may be formed in the space between the upper plate 31 and the lower plate 32, or the heat-resistant insulating material 40 may be embedded therein. The lower end of the double lid 30 is in contact with the seating portion 23 of the inner pot 20 to seal the space portion of the inner pot 20.

Combining or separating the double pot 1 having the cooking and keeping function of the present invention thus constructed will be described with reference to Figs. 2 and 3. Fig.

First, in FIG. 2, the inner pot 20 is connected to the outer pot 10 by combining water into the inner pot 1 to add water to the inner pot 20 and boil or add the ingredients. That is, when the inner pot 20 is inserted into the outer pot 10, the upper end of the guide protrusion 11 having the mountain and the valley formed on the inner peripheral surface of the outer pot 10 and the mountain and the valley of the outer peripheral surface of the coupling portion 21 of the inner pot 20 are formed The lower end of the sliding projection 22 contacts. At this time, when the knob 24 of the inner pot 20 is rotated clockwise by holding the handle 12 of the outer pot 10, the guide protrusion 11 and the sliding protrusion 22 are screwed together. When the inner pot 20 is continuously rotated, the bottom of the inner pot 20 comes into contact with the bottom of the outer pot 10. At this time, it is preferable that the handle 12 of the outer pot 10 and the handle 24 of the inner pot 20 come to be at the same vertical position or in the direction of 180 degrees. The bottom of the outer pot 10 and the bottom of the inner pot 20 are in intimate contact with each other when the inner pot 20 is fully engaged with the outer pot 10. The inner pot 1 is placed on the heating device and heated The heat is heated to the bottom of the surface pot 10 and is conducted to the inner pot 20 which is in contact with the surface pot 10. [ Therefore, the foodstuff contained in the inner pot 20 is cooked. In addition, while the inner pot 20 is warmed, the heat that can be generated due to the endless heating of the side surface space between the outer pot 10 and the inner pot 20 is blown through the through holes formed in the outer pot 10, The space portion can be prevented from being expanded.

Next, in Fig. 3, when the cooking in the double pot 1 is completed, it is necessary to keep the food stored in the deep-fry pan 20 for a predetermined time. That is, when the handle 24 of the inner pot 20 is rotated counterclockwise by holding the handle 12 of the outer pot 10, the engagement of the inner pot 20 and the inner pot 20 along the guide protrusion 11 of the outer pot 10, The sliding protrusion 22 on the outer peripheral surface of the portion 21 is lifted. The bottom of the inner pot 20 is separated from the bottom of the outer pot 10 and the bottom of the inner pot 20 is spaced apart from the bottom of the outer pot 10 at regular intervals. Therefore, the inner pot 20 is formed with the space portion formed on the side surface of the outer pot 10 and the joint portion and the bottom portion respectively from the bottom so that the heat of the food in the inner pot 20 is insulated by the space portion, Insulation is made for a period of time.

Furthermore, the double lid 30 covering the double pot 1 can prevent the heat of the food contained in the deep-fry pan 20 from being released to the outside, thereby keeping the frypot 20 warm.

When cooking is performed by combining the surface pot 10 and the inner pan 20, it is possible to perform heating at a position vertically close to the position between the handle 12 of the surface pot 10 and the handle 24 of the inner pan 20 And it is possible to judge that the heating can be performed when the handle 12 of the outer pot 10 and the grip 24 of the inner pot 20 maintain a certain distance up and down.

When the outer pot 10 and the inner pot 20 are separated from each other and each of them needs to be cleaned, the handle 24 of the inner pot 20 is held in the counterclockwise direction by holding the handle 12 of the outer pot 10 The guide pot 11 can be easily separated because the guide protrusion 11 of the screw pan 10 is detached by coming into contact with the sliding protrusion 22 of the outer circumferential surface of the engaging portion 21 of the inner pot 20 .
