Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure cooker, and an object of the present invention is to provide a pressure cooker that can seal a pot and a lid with a simple operation.

In a conventional pressure cooker, a notch is formed in the upper end flange of the pot, and a notch is also formed in the outer periphery 7 flange of the lid, and by horizontally rotating the lid, the upper 7 flange and the outer 7 flange can be separated. engage. A sealed container was obtained by so-called bayonet engagement. However, this conventional pressure cooker has notches formed on both flanges, making the shape complicated and difficult to clean.Also, when using the cooker, the positions of the notches in the pot and the notch in the lid must be adjusted. There is a need, etc.
It was not easy to use.

In the present invention, the pot flange portion and the lid 7 lunge portion are overlapped.

The present invention attempts to solve the above-mentioned drawbacks of the conventional art by attaching an arch-shaped clamping tool having a substantially U-shaped cross section to both flanges to construct a sealed container. Examples will be described with reference to the accompanying drawings.

In the figure, 1 is an outer body, and an inner body 3 is provided inside the outer body 1 with a heat insulating material 2 interposed therebetween. 4 is a heating element disposed at the inner bottom of the inner body 3;

6 is a cylindrical pot with a bottom that is removably placed on the heating element 4. A pot flange portion 6 is formed at the upper end of the pot 5. The cover is an outer lid that covers the outer body 1, and an elastic holder 8 is attached to the center of the lower surface. Reference numeral 9 denotes a lid that covers the upper opening of the pot 6, and a mounting shaft 10 that protrudes upward in the center.
is fixed. This attachment shaft 1o is detachable from the holder 8, and when attached to the holder 8, the outer lid 7 and the lid 9 are integrated. Reference numeral 11 denotes a lid flange portion formed on the outer periphery of the lid 7, which is overlapped with the pot flange portion 6 and has a backing 10a.
to hold. Reference numeral 12 denotes a handle disposed on the outer periphery of the pot flange portion 6, and has a substantially arcuate shape.

Reference numerals 13 and 14 designate a pair of clamping tools that are horizontally rotatably supported at both ends of the handle 12, and have an approximately U-shaped cross section and an arched shape, and hold the pot flange portion 6 and the lid flange portion 11 which are stacked one on top of the other. It is something to hold. Further, 16 is an arch-shaped fixed clamp having a substantially U-shape on the road surface.

It is fixed to the inside of the handle 13 and holds the stacked pan 7 rank part 6 and lid 7 rank part 11. Reference numeral 16 denotes a contact portion with which the handle-side ends of the clamps 13 and 14 come into contact when the handle 12 is moved in a direction away from the pot 6;
It is provided on the upper surface of the internal water body 3.

In the above configuration, the clamping tools 13, 14. Fixed clamp holder 1
5, in the state shown in FIG. 2, the clamping tools 13, 14 and the fixed clamping tool 15 clamp the pan flange part 6 and the lid flange part 11 which are overlapped with each other via the backing 10a. ing.

Next, as shown in FIG. 3, when the handle 12 is pulled out and moved in the direction away from the pot 5 (in the direction of the arrow), the fixed clamping tool 15 separates from the 7 langes 6.11, and the clamping tool 13
．． The handle side end of 14 is arrow B.

It moves in the direction B, leaves both flanges 6.11, and comes into contact with the abutment part 16. Further, the end portions of the clamping tools 13 and 14 on the side opposite to the handle move in the directions of arrows C and C, but they continue to clamp both flanges 6 and 11. Next, as shown in FIG. 4, when the handle 12 is further moved in the direction indicated by the arrow, the clamping tools 13 and 14 are in contact with the abutting portion 16, so the end of the first handle moves in the direction indicated by the arrow D. 1.The end opposite to the handle is indicated by arrow E.
.

It moves in the depth direction and leaves both 7 lunges 6.11. In this state, the lid 9 can be opened.

Next, a method of attaching the clamp holders 13, 14 and the fixed clamp holder 16 to both 7 flange portions will be explained.

Cover the pot 6 with the lid 9 and attach the backing IQ to the pot flange 6.
Stack the lid flange parts 11 through a, and connect the 1 handle 12 to the pot 6.
When the clamping tools 13 and 14 are pushed toward the center, the handle-side ends of the clamping tools 13 and 14 move in the directions of arrows F and i, and the opposite ends of the gripping tools move in the directions of arrows G and G. Clamp parts 6 and 11. Further, the fixed clamp holder 16 also moves in the direction of arrow H and clamps both the 7 flange portions 6 and 11. By pulling out the handle 12 in this way, the clamping tool 13°1
4 and the fixed clamp 15 are separated from the flange portions 6° 11 of both 7 to enable the lid 9 to be opened, and conversely, when the handle 12 is pushed toward the center of the pot 6, the clamps 13° 14 and the fixed clamp 16 are released. A sealed container can be obtained by sandwiching both 7 flange parts 6° 11, and the operation is very simple. Further, the pot flange portion 6 and the lid flange portion 11 have no notches, making cleaning extremely easy.

As is clear from the above description, the pressure cooker of the present invention is extremely easy to operate as it is possible to obtain a sealed container by simply moving the handle. Since the structure is simple and cleaning is easy.
