Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure jar rice cooker equipped with a pressure cooking function and a long-term heat retention function. In other words, a pressure vessel consisting of a pot and a pressure lid housed in a heat insulating container consisting of a main body and a lid having an insulated structure, when the internal pressure is rising or is in a state where the internal pressure can rise, the lid can be removed from the heat insulating container. It was made so that it could not be opened. Conventionally, when the internal pressure of the pressure vessel is in a rising state, the pot and pressure lid are airtightly connected, so when the lid is opened, the pressure lid fitted with the lid is lifted by unscrewing the pot. There was fear. Therefore, in such cases, if vibrations etc. are applied to the pressure vessel, the internal steam may suddenly blow out from the pressure valve for adjusting the internal pressure, or the pressure vessel may come off the lid due to the weight of the pot and fall. There were drawbacks. In the present invention, the pressure lid can be opened by opening the lid only when the pressure lid is not connected to the pot, and the lock prevents the lid from being opened when the pressure lid is connected to the pot. The purpose is to provide a mechanism.

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

Reference numeral 1 denotes a protective frame with a rice cooking heater attached to the inner bottom, and a heat-retaining heater 2 for keeping the rice warm at the outer upper part. 3 is an upper frame made of a ring-shaped resin material integrally molded with a fitting part 3a and a hinge part at the other end; a protective frame 1 is attached to the upper part of the inner periphery, and a body 4 is fitted to the lower part of the outer periphery. Heavy structure body 6
A cylindrical pot 6 with a bottom is removably housed inside. Reference numeral 7 denotes a pressure lid that airtightly covers the upper opening of the pot 6 via a pot gasket 8, and as shown in FIG. On the other hand, the upper opening of the pot 6 is provided with a notch 6b corresponding to the locking part 7b, and the other part is formed with a fitting part 6a having a cross-sectional shape that holds the locking part 7b. are doing. When the locking part 7b overlaps with the lower surface of the fitting part 6a, the pot 6 is sealed by the pressure lid 7, thereby forming a pressure vessel. A nozzle 9 is provided on the pressure lid 7 in order to blow out the steam inside the pot 6 and adjust the internal pressure when the internal pressure of the pot 6 rises too much, and the tip of this nozzle 9 is normally blocked by a weight 1o. ing.

In addition, the pressure lid 7 has a holding shaft 11 on the upper center surface of the pressure lid 7.
It is connected to the connecting shaft 12 via the connecting shaft 12.
An inner lid 14 is provided at the bottom of the pressure lid 7, and an inner lid gasket 13, which is removably fitted to the lower end of the pot, is inserted in the center thereof.

It is supported by the outer peripheral wall of the inner lid 14 at the lower peripheral edge under the pressure lid. ：S・15 is an outer cover made of a resin material with a handle part integrally molded.
- A hook lever 18 is rotatably supported at 6 and has a hook button 17 fixed to the other end. Reference numeral 19 denotes a heat dissipation plate provided on the inner surface of the outer lid 16, a lid heater 20 for heat retention is pasted on the top surface, a flexible holder 21 is inserted into the central through hole, and a holding shaft is fastened to the pressure lid 7. 11 is mounted on this holder 21 in a detachable and rotatable manner.

In this way, the lid body 22 has a double structure including the outer lid 15 and the heat sink 19. Reference numeral 23 denotes a lock shaft provided below the hook button 17, which has a buckle 23a in the center, the upper part of which is inserted into a through hole of the outer cover 15 and pivoted so as to be movable up and down, and comes into contact with the lower surface of the hook lever 18. The lower part is roughly bowl-shaped and comes into pressure contact with the lower surface of buckwheat 23a, and is slidably inserted into a through hole in the center of a lock gasket 24 made of silicone rubber, flexible plastic, or the like. Above, the lock gasket 24 is inserted into the through hole of the heat dissipation plate "11-19, and the lock shaft 23 is moved upward.
The effect.

It is something that is pressing down.

Here, the main body 6 is covered with the lid body 22 and the pressure is
1. When enabling rice cooking, the pot 6 is housed in a regulated position within the protective frame 1, and a holder 2 is inserted into the bottom surface of the lid body 22.
1 to fit the holding shaft 11 of the pressure lid 7. When the pressure lid 7 is locked to the lid body 22 at the position where the locking part 7b of the pressure lid 7 corresponds to the notch part 6b of the pot 6 and the lid is covered with the main body 6, a hook lever 18 formed at the lower end of the scene-shaped hook lever 18 is inserted. Lock claw part 19a
When the pressure lid 7 is engaged with the fitting part 3a of the upper frame 3 and locked, the engagement part 7b of the pressure lid 7 is accommodated in the notch 6b of the pot 6.

Next, when the pressure knob 25 directly connected to the pressure lid 7 and located on the outside of the main body 5 is rotated in the closing direction, the locking portion 7a of the pressure lid 7 enters the fitting portion 6a of the pot 6 and is overlapped. The container is sealed and becomes a pressure vessel, allowing pressure cooking. At this time, when attempting to open the lid body 22, the upper and lower ends of the lock shaft 23 pressed by the lock gasket 24 come into contact with the lower surface of the hook lever 18 and the upper surface of the pressure lid 7, making it impossible for the hook button 17 to move. Therefore, when the pressure lid 7 is connected to the pot 6, the lid body 22 cannot be opened.

Conversely, when opening the lid body 22, rotate the pressure knob 26 in the opening direction to return the pressure lid 7 to the position before fitting, and press the hook button 17. The lock shaft 23 that was in contact with the top surface descends into the recess 7c provided on the top surface under the pressure cover, and as a result, the hook button 17 moves, and the hook lever 18 rotates around the fulcrum shaft 26 to release the
The claw portion 18a moves in a direction away from the upper frame 3, and is disengaged from the fitting portion 3a, allowing the lid 22 to be opened. When the hook button 17 is released, the lock shaft 23 is moved from its original upper position by the lock gasket 24 and is always in contact with the lower surface of the hook lever 18.

Therefore, in this embodiment, the main body housing the pot covered by the pressure lid and the lid covering this main body can be opened only when the pot is not sealed, and the outer cover and the heat sink are double-layered. A seesaw-type hook lever that is connected to the main body is attached to the lid, and a lock is attached below a hook button fixed to one end of the hook lever, which abuts the lower surface of the hook lever and protrudes downward from the heat sink. position the axis,
The upper portion of the collar formed in the center of this lock shaft is inserted into the through hole of the outer cover so as to be able to move up and down, and has a through hole in the center in which the lower part of the lock shaft slides, and is pressed into contact with the lower surface of the sleeve. Since the lid locking mechanism of the cooker is constructed by inserting a roughly bowl-shaped flexible locking gasket into the heat sink, the following effects can be achieved.

In other words, the locking mechanism of the lid takes into consideration the safety of the pressure vessel housed in the heat-insulating container consisting of the main body and the lid, so the lock shaft located below the hook button that serves as the lid lock release button is used to dissipate heat. A roughly bowl-shaped flexible lock gasket inserted into the plate normally brings the hook button into contact with the lower part of the fixed hook bar, and the lock shaft that protrudes downward from the through hole of the lock gasket controls the movement of the hook lever. By interlocking and movable up and down, and providing good airtightness to prevent steam from entering the lid between the through hole and the lock shaft, this will impede the insulation and lifespan of the lid heater inside the lid. The heat retention performance can be maintained at □・11°, and the outer lid made of resin material will not be deformed.

The lid can be opened only when the trench pressure vessel is not sealed, making it impossible to accidentally open the lid when the internal pressure of the pot is rising, further improving safety, performance, quality, reliability, etc. be able to.

As described above, the present invention has a hook button fixed to one end of a hook lever that connects a main body housing a pressure vessel consisting of a lid and a pot to a lid covering the main body, and the upper end of the hook button is fixed to one end of the hook lever. To provide a cooker with good safety by locating a lock shaft that contacts a button and is biased upward so that the lid can be opened only when the lid and the pot are not connected. It is a valuable dog.
