Abstract

The present invention relates to a vacuum pot which can be kept in a vacuum state by a simple structure. The vacuum pot comprises: a pot container (500) which accommodates food; a lid (100) covering the pot container (500); a handle (200) mounted on the lid (100); an edge packing member (400) for sealing the pot container (500) and the lid (100) to each other; and a check valve (300) which is opened when an expansion pressure is generated while food in the pot container (500) boils and closed when a contraction pressure is generated while the food in the pot container (500) cools down. The expansion pressure that is generated while food boils during cooking simply pushes up the check valve and the vacuum packing member of the handle so that steam is discharged. The contraction pressure generated when a heating power is cut off and the food cools down pulls the check valve and the vacuum packing member of the handle so that the pot is kept in a vacuum state.

Description

vacuum pot {VACUUM POT}

The present invention relates to a vacuum pot, and more particularly, to a vacuum pot for boiling food so that it can be stored in a vacuum state.

In general, a pot consists of a container and a lid and is used to boil or cook food, and has a structure in which water vapor is discharged through a gap between the container and the lid or a steam hole provided on the lid when boiling or cooking food.

In the conventional registered utility model No. 20-0152284, the synthetic resin material body (1) has an annular indentation on the outer periphery of the body and inserts the body (1) into the binding hole (H) of the lid (C) for coupling. (2) and; The lid (C) is integrally formed on the upper surface of the insertion groove (2) so as to have only the function of evacuating the air inside the lid (C), and the annular non-return flange part (3) having a thickness reduced downward and inclined downward; a plurality of concave grooves for exhaust (4) formed in the vertical surface and the lower surface of the insertion groove (2) to form a passage through which the air inside the pot (B) is discharged; It is known that the display unit 5 integrally formed on the upper surface of the main body 1 so as to be able to be contracted and eluted so as to visually measure whether the pot B is sealed is configured to be combined with each other.

In a pot configured to cook food by placing a lid 20 assembled with a tap 30 on an upper part of a container 10 with an open top as an embodiment of a conventional design in Registered Utility Model Room No. 0132659, when heating The high pressure generated is automatically evacuated, and at the same time, it is automatically sealed so that outside air is not introduced during cooling, and the sealed state can be easily identified from the outside and sealed on the lid 20 to minimize the overflow of food. The present invention is that the structure 70 is installed, the elastic opening and closing part 40 is installed between the lid 20 and the faucet, and the elastic sealing part 50 is provided between the container 10 and the lid 20 at the same time. is the main characteristic of

The packing 510 is made of an elastic synthetic resin or rubber material that can sufficiently withstand high heat. And, by placing the back-out blocking flange 60 to block the direct movement of the boiling contents to the edge of the container 10, it plays a role of enclosing and confining the boiling broth in a bubble state, etc. to prevent overflowing by boiling. .

However, a general pot is easy to boil or cook food, but because it is stored with a lid simply covered on the container, the food is easily spoiled or changed.

Therefore, conventionally, a pot equipped with a check valve for sealing the pot and discharging steam generated when cooking food by heating the pot has emerged. A phenomenon in which food is easily spoiled or changed because it is not completely sealed is still required, so a technology of a pot that is sealed with a packing member formed on a handle and a rim is required.

The present invention makes it possible to seal the inner space between the container and the lid by the rim packing member, and the expansion pressure generated when food boils during cooking simply pushes up the check valve and the vacuum packing member, and steam is discharged, When the heat is cut off and the food cools, the contracting pressure that is generated pulls the check valve and the vacuum packing member to keep the pot in a vacuum state. It is to provide a vacuum pot that can eliminate the pouring state by preventing the pot from being opened due to a shock or the like when the pot becomes a vacuum when transported in a vehicle.

The present invention provides a pot container (500) for accommodating food, a lid (100) covered on the pot container (500), a handle (200) mounted on the lid (100), a pot container (500) and a lid (100) ) Check that the rim packing member 400 for sealing each other and the pot container 500 are opened when the food in the pot container 500 boils and expansion pressure is generated, and closed when the food in the pot container 500 cools and a contractile pressure is generated. It is composed of a valve 300, and the expansion pressure generated when food boils during cooking simply pushes up the check valve and the vacuum packing member of the handle, and the steam is discharged, and when the heat is cut off and the food cools, the contraction pressure generated is reduced. Pull the check valve and the vacuum packing member of the handle to keep the pot in a vacuum state.

The present invention is composed of a pot container in which food to be cooked is stored and a lid that seals the upper part of the container, is mounted on the lid of a cooking container used to cook food by a heating action, and discharges pressure generated during heating to the outside. When heating is completed at the same time, the present invention relates to a vacuum pot that allows the freshness of cooked food to be maintained for a long time by vacuuming the inside of the container.

In addition, the present invention makes it possible to seal the inner space between the container and the lid by the rim packing member, and is opened and closed according to the expansion and contraction pressure by the check valve and the vacuum packing member to discharge the pressure and the vacuum state. By making it possible to maintain, it is possible to discharge steam and maintain a vacuum state by a simple structure, while the check valve and handle are detachable, so there is a hygienic and clean effect due to the ease of cleaning.

In addition, the vacuum pot is effective even during transport, which can eliminate the pouring state by preventing the lid from being opened due to impact or the like during transport in a vehicle as the pot becomes vacuum.
