Fig.

1 and 2, a vacuumable pot 100 according to the present invention includes a container 200 having a cooking chamber 200a, a vacuum lid (not shown) for opening and closing the cooking chamber 200a of the container 200 300).

The container 200 is formed with a bottom 210 and a side wall 230 protruding from the edge of the bottom 210 to form a cooking chamber 200a therein as shown in FIG.

As shown in FIGS. 2 and 3, the vacuumable lid 300 includes a lid body 310, at least a portion of which is transparent or semitransparent so as to be visible inside the container 200, A packing 370 and a packing support assembly 400 for supporting the packing 370 on the rim of the lid body 310. [

The lid body 310 may be embodied as whole transparent glass or partially transparent or translucent reinforced plastic, but tempered glass is preferred.

Particularly, the check valve 350 is disposed in the lid handle 330 installed in the through hole 311 formed at the center of the lid body 310.

3, 6A, and 6B, the lid handle 330 includes a hollow core 330a disposed on the through hole 311, and a hollow core 330b coupled to the hollow core 330a to be coupled to the lid body 310 And an arm 330c protruding in the radial direction of the lid body 310 from one side of the hollow cap portion 330b. Further, the lid handle 330 is formed of a plastic material resistant to heat.

The check valve 350 is movably mounted in the hollow core 330a and the upper portion of the check valve 350 protrudes above the upper end of the hollow cap 330b.

With the configuration of the lid handle 330, a single lid handle can simultaneously satisfy the vacuum function, the overflow prevention function, and the lifting function.

As shown in FIG. 6B, the through-hole of the hollow core 330a serves as a passage for discharging the water vapor generated in the container 200.

At the lower end of the hollow core 330a, a latching flange 331a is formed which is hooked on the bottom surface of the lid body 310. [

The engaging flange 331a is caught by the lower surface of the through hole 311 when the upper end of the hollow core 330a is inserted into the through hole 311 from below.

A male screw 333a is formed on the outer peripheral surface of the hollow core portion 330a. Since this male thread 330a is formed between the engaging flange 331a and the upper end of the hollow core 330a, there is a certain height difference between the upper end of the hollow core 330a and the through hole 311.

The hollow cap portion 330b has a cylindrical or cylindrical shape penetrating up and down, and a female screw 333b fastened to the male screw 333a is formed on the inner peripheral surface.

The female screw 333b is also formed between the lower end of the hollow cap portion 330b and the upper end, particularly the lower end of the hollow cap portion 330b, between the discharge hole 320 described later.

Therefore, the height between the upper and lower ends of the hollow cap portion 330b is somewhat deep.

As shown in FIGS. 1 to 3, a discharge hole 320 is further formed at one side of the hollow cap portion 330b.

3, 6A and 6B, the discharge hole 320 is disposed above the upper end of the hollow core 330a so that when the water vapor exits the discharge hole 320, Do not disturb the top.

That is, as shown in FIG. 6B, when the water vapor is going to come out upward, the water vapor escapes to the discharge hole 320, thereby preventing condensation of water vapor due to a difference in height (depth) of the hollow cap part 330b, It is possible to prevent the water from flooding.

The discharge hole 320 is formed to pass through a rectangle having a long length from the top and the bottom to the left and right.

Further, it is preferable that the discharge hole 320 is disposed at a position facing the arm 330c.

The arm 330c protrudes in a radial direction of the lid body 310 from one side of the hollow cap part 330b when viewed from a plane and is inclined upward toward the rim from the center side of the lid body 310 when viewed from the side .

Therefore, the end of the arm 330c and the rim of the lid body 310 can stably erect the lid 300 that can be vacuumed.

Meanwhile, as shown in FIGS. 6A and 6B, the hollow cap part 330b is provided with a guide piece 340 for guiding upward the steam.

Particularly, the guide piece 340 is disposed at a position where the hollow cap 330b and the arm 330c meet, and serves as a detour for bypassing upward the water vapor directly toward the arm 330c.

In order to function as a detour, a guide piece 340 is provided on a part of the upper surface of the hollow cap part 330b as if it surrounds the wall.

The check valve 350 is made of a silicone material which is elastically deformable and harmless to the human body and has an opening and closing flange 351 placed on the upper face 337a of the opening and closing hole 335a formed in the hollow core portion 330a as shown in Figs. 6A and 6B, A hollow flange 355 attached to the lower surface 338a of the opening and closing hole 335a and a hollow flange 355 formed in the upper portion of the opening and closing flange 351, And a flange 359 formed between the stem 353 and the opening and closing flange 351. The flange 359 is formed of a metal plate.

The connection portion 357 is implemented as a plurality of connection strips 357 provided at predetermined intervals to form the discharge space S along the periphery of the hollow flange 355.

The shape of the stopper 353 may be hand-held.

The opening and closing flange 351 is of a flange type protruding outward from the lower side of the stem portion 353 so as to have a larger diameter than the diameter of the opening and closing hole 335a.

The hollow flange 355 has a disk shape and a through hole 356 is formed at the center thereof.

With this configuration, the check valve 350 forms a flow path through which the pressure inside the cooking chamber 200a is discharged to the outside through the through hole 336 and the discharge space S of the hollow flange 335c, The flow path is a one-way valve that blocks.

On the other hand, the diameter of the flange 359 is larger than that of the opening / closing flange 351 to function as an umbrella again and to be smaller than the diameter of the through-hole of the hollow cap portion 330b so that water vapor or the like is released into the edge gap c desirable.

In other words, the flange 359 functions as an umbrella for minimizing overflow when the foreign object overflows through the opening / closing flange 351.

On the other hand, as shown in Figs. 6A and 6B, it is preferable that a plurality of holes 359a are formed in the flange 359. Fig.

Since the clearance (c) is very narrow, water vapor that is discharged becomes a bottleneck and drips with time. When water droplets are formed, when the water vapor is continuously discharged, the water droplets are fried outward due to the pressure, resulting in dirty or burning.

Therefore, the hole 359a serves as an exhaust passage for water vapor as shown in FIG. 6B, thereby relieving the discharge bottleneck of water vapor and preventing water droplets from forming in the clearance c.

The packing 370 is an integral ring of a closed loop and includes a rim packing 371 that is largely fitted to the rim 312 of the lid body 310 as shown in Figs. 3, 3A, and 4, And a vacuum packing 373 placed on the upper end 231 of the vacuum chamber 200.

3 and 3A, the rim packing 371 includes an upper flange 371a, a lower flange 371b, and an upper flange 371a disposed on the upper and lower surfaces of the rim 312 of the lid body 310, And a web 371c connecting one end of the lower flange 371b.

The vacuum packing 373 includes a blade piece 373a placed on the upper end 231 of the container 200 as shown in Figs. 3, 3A, 4 and 5, and a blade piece 373a on the other end of the lower flange 371b, And a connecting piece 373b connecting the other ends of the connecting pieces 373b.

When the lid 300 is pushed downward when the lid 300 is later placed on the upper end 231 of the container 300, the air inside the container 200 is separated from the lid 373a and the upper end 231) to create a vacuum state.

A projecting rib 375 is formed on the upper surface of the blade piece 373a.

As shown in Fig. 5, the projecting ribs 375 are formed at predetermined intervals along the periphery of the blade piece 373a.

Therefore, the projecting rib 375 is formed so that the blade piece 373a abuts on the lower surface of the base 411 by reducing the contact area by line contact or point contact instead of surface contact with the entire lower surface of the base 411 .

Further, as shown in Fig. 5, it is preferable that the protruding ribs 375 have different heights at both ends.

That is, the outer height h of the protruding rib 375 is set to be lower than the inner height H, and the height is increased from the outer side to the inner side of the blade piece 373a.

Since the inner protruding rib 375 first touches the bottom surface of the base 411 and the resilient repulsive force is much larger than the outer protruding rib 375, when the external force is removed, So as to be more easily detached from the lower surface of the base 411.

On the other hand, the projecting ribs 375 may be discontinuously formed. That is, one protruding rib 375 may be disposed in a plurality of protruding ribs.

The protruding ribs may be formed continuously or discontinuously along the circumference of the blade piece 375a.

This packing 370 is supported by a rim 312 of the lid body 310 by the packing support assembly 400.

The packing support assembly 400 has an annular shape as shown in Figs. 3, 3A, and 4 and includes a lower frame 410 that supports the bottom surface of the lower flange 371b, and a lower frame 410 that supports the upper surface of the upper flange 371a A frame 430 and a fixing part 450 for supporting and fixing the lower frame 410 by the upper frame 430.

The lower frame 410 is composed of a base 411 for supporting the bottom surface of the lower flange 371b and a lower upwardly extending piece 413 extending upward from the upper surface of the base 411 so as to face the web 371c.

Accordingly, the lower frame 410 is formed of a ring of 'b' letters.

The upper frame 430 includes a ceiling 431 for pressing the upper surface of the upper flange 371a and an upper downward extending piece 433 extending downward from the outside of the ceiling 431 to face the lower upwardly extending piece 413 Consists of.

The inner portion of the ceiling 431 has a length extending over the upper surface of the lid body 310.

As shown in FIG. 3A, the fixing part 450 is bent inward from the upper downward extending piece 433 to support and fix the lower frame 410.

That is, the upper portion of the fixing portion 450 bent inward from the upper downward extending piece 433 is supported by an edge portion where the base 411 and the lower upward extending piece 433 meet.

The lower frame 410 and the lower frame 410 are fixed to each other so that the lower frame 410 is pulled downward by the fixing portion 450 ≪ / RTI >

In order to bend the fixing part 450, the upper frame 430 is formed of a stainless steel material having high corrosion resistance in this embodiment.

The stainless steel upper frame 430 also protects the lower frame 410 (for example, protects against scratches or shocks).

Like the upper frame 430, the lower frame 410 is preferably made of metal, preferably stainless steel.

When the upper frame 430 is made of stainless steel, as shown in FIG. 3A, when the folded portion 431a curled inward is formed in the inner portion of the ceiling 431, the edges of the metal are rounded to form a rounded shape, And serves as a finishing portion for preventing a step difference with the upper flange 371a and preventing foreign matter from entering from the outside.

It is also preferable that a folded portion 433a is formed at the lower end of the upper-side downward extending piece 433.

In particular, it is preferable that the lower end of the upper-side downward extending piece 433 is located at the same position as or lower than the lower end of the blade piece 373a by? Y.

The difference is that when the lid 300 is placed on the container 200, the lower end of the upper downward extending piece 433 does not rest on the upper end 231 of the container 200 but lies on the outer side thereof, .

6B). When the pot 100 is not boiled, the inner pressure of the container 200 is expanded while the inner pressure of the container 200 is lowered (see FIG. 6B) The inner pressure is contracted while the vacuum-enabled lid 300 and the check valve 350 are pulled.

That is, when the vacuum-enabled lid 300 is pulled, the inside air of the container 200 is evacuated between the blade piece 373a and the upper end 231 to evacuate the inside.

Therefore, the blade piece 373a and the check valve 350 do not allow external air to flow, so that the cooking chamber 200a of the pot is formed in a vacuum state (see FIG. 6A).

The release of the vacuum state may be boiled or held by holding the stem 353 of the check valve 350 and then lifted up.

On the other hand, with the configuration of the check valve 350, the lid 300 which can be vacuumed when cooking is boiled overflows to the upper end 231 of the container 200 while it is heard.

To prevent this, it is preferable that a lid locking member 700 is further installed on the container handle 500 provided in the container 200.

The container handle 500 is screwed to the side wall 230 of the container 200.

The lid locking member 700 is composed of a locking slider 710 and a guide member 730 for guiding the locking slider 710 in the radial direction with respect to the container handle 500 as shown in Fig.

Further, it is preferable that an elastic clip (not shown) for determining the position of the locking slider 710 is further provided on the guide member 730.
