Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device that can cook cooked rice under pressure, keep it warm for a long time, and cook delicious rice.

BACKGROUND ART Rice cookers with a jar, which have an integral structure of a container for cooking rice and a container for keeping it warm for a long time, are now widely used.

Conventional rice cookers with a jar of this type have two methods: one that cooks rice while keeping the heat constant, one that incorporates a timer or microcomputer to adjust the heat, and one that restricts the steam outlet to prevent steam and heat. There was a method of cooking rice by reducing the amount of water escaping, increasing thermal efficiency, and increasing the internal pressure.

The present invention relates to the last of the three methods described above, and has a structure in which rice is cooked by increasing the pressure inside the pot and can be kept warm for a long time.

An embodiment of the present invention will be described in detail below.

Double structure body 2 with insulation material 1 interposed inside
A cylindrical pot 3 with a bottom is removably housed inside.

The opening of this pot 3 is covered with a pressure lid 4 via a packing 5. A flange 6 formed at the opening of the pot 3 is intermittently provided with notches 7 to form claws 8, and a flange 9 formed at the periphery of the pressure lid 4 is intermittently provided with notches 7. 10 is provided to form a claw portion 11. By superimposing the claw part 11 on the lower surface of the claw part 8, the pot 3 is sealed by the pressurizing lid 4 to form a pressure vessel, and the internal pressure of the pot 3 increases.

A nozzle 12 is provided on the pressurizing lid 4 to adjust the internal pressure by blowing out steam inside the pot 3 when the internal pressure of the pot 3 rises and becomes dangerous. It's blocked.

A double-structure outer lid 14 that covers the main body 2 to form a heat-retaining container is rotatably supported on the main body 2 by a hinge shaft 15. A holder 16 is provided at the center of the back surface of the outer lid 14, and a mounting shaft 17 provided on the pressure lid 4 is detachably and rotatably attached to this holder 16, so that the upper surface of the pressure lid 4 is attached to the outer lid 14. covered with.

When the main body 2 is covered with the outer lid 14, the lock claw formed at the lower end of the seesaw-shaped foot lever 18 is locked with the main body 2, and the foot lever 18 is locked.
When the foot lever button 19 fixed to the upper end is pushed against the elasticity of the spring 25, the foot lever 18 rotates around the fulcrum shaft 20, and the lock claw portion moves away from the main body 2, and the outer cover is closed. 14
can be opened. The combination of the pot 3 and the pressure lid 4 by the overlapping of the claws 8 and 11 and the separation of the pot 3 and the pressure lid 4 by separation of the claws 8 and 11 are achieved by protruding the pressure lid 4 from the outer lid 14. This is done by rotating the handle 21. Note that the outer cover 14 is provided with a through hole 26 through which the nozzle 12 protrudes and moves.

The pot 3 is heated by a heater 22, which is controlled by a controller 23.

Therefore, by overlapping the claws 8 and 11, the pot 3 is sealed by the pressure lid 4 and pressure cooking becomes possible;
are each covered by an outer lid 14, and since the main body 2 and the outer lid 14 are locked and integrated, they are shielded from heat and can be kept warm for a long period of time. Note that by providing the heater 24 on the outer lid 14, the heat retention effect becomes better.

The rotation of the pressurizing lid 4 is controlled by the holder 16 and the mounting shaft 1.
7 and the handle 21 is located away from the center of rotation, the rotation torque can be reduced and the rotation is stabilized so that the flange portion 9 of the pressurizing lid 4 can be rotated in the direction of the pot 3. Smooth rotation can be achieved without contacting the flange portion 6.

As described above, the present invention constitutes a heat insulating container with a main body having a heat insulating structure and an outer lid having a heat insulating structure covering the main body, and inside this heat insulating container, a pot having a claw portion at the opening and a pot having a claw portion in the opening portion are provided. A pressure vessel formed by a pressurizing lid having an overlapping claw portion is housed, and the pressurizing lid is rotatably attached to the outer lid by fitting the holder and the mounting shaft. If the pressure lid is to be connected to the pot by the overlapping of the claws or separated by separation of the claws, the handle should protrude outside of the heat-insulating container. Since the handle is located away from the center of rotation of the pressure cover and outer cover, the rotation torque is small and the pressure cover can rotate smoothly. The pressure lid and the outer lid are integrated by fitting the holder and the mounting shaft, so when the outer lid is closed, the pressure lid is naturally positioned and fitted into the pot. It is effective.
