Description

[Detailed Description of the Invention] The present invention relates to an electric cooker such as a so-called electric jar rice cooker, and in particular, an auxiliary lid is provided on the lid for opening and closing the pot.

A regular electric jar rice cooker consists of a lid that opens and closes the opening of the inner pot that is housed in a detachable manner, and a lid body with an iron lid that can be attached freely and pivoted to the frame body so that it can be opened and closed. The steam generated during rice cooking passes through a small hole provided approximately in the center of the lid and is released to the outside at a steam vent provided in the lid and in communication with the outside air.

At this time, the slime in the steam accumulates on the top surface of the lid, and only the steam is released to the outside through the steam release part.
The lid communicates with the outside air only through the small hole as described above, and has the disadvantage that steam cannot be effectively released into the inner pot, which has a relatively high internal pressure.

In other words, the steam generated during the rice cooking operation flows to the upper surface of the small hole, forms bubbles, and blocks the hole.The bubbles burst and are released from the steam release part, causing steam and sticky water to flow out. The separation was incomplete.

The present invention was developed in view of the various points mentioned above, and will be explained below based on the drawings. 1 is a cylindrical frame, 2 is an outer pot housed in the frame 1, and 3 is a pot inside the outer pot 2. The inner pot 4, which is housed in a detachable manner, has a step 5 on the outer periphery, and is an inner lid for opening and closing the upper opening of the inner pot 3, and has a bulge 6 projecting upward in the center. A knob 7 provided on the bulge protruding upward, a plurality of small holes 8, 8 bored on the outer side of the bulge 6, and a trident-shaped shielding plate partially cut out upward to the road edge. A guide tube 11 is provided which is located inside the shielding plate 9 from the inner circumferential surface of the steam outlet hole 10 and is lower than the upper end of the shielding plate 9 and protrudes upward. It is fixed, and a play hole 12 is bored in a part.

13 is placed with its outer peripheral edge on the stepped portion 5, has a through hole 14 for the knob 7 in the center thereof, and further has a part thereof attached to the shielding plate 9.
The auxiliary lid is placed on the inner lid provided with a through hole 15, and is provided with a protruding pin 16 which is fixed and protrudes downward in correspondence with the play hole 12.

The outer peripheral edges of the inner lid 4 and the auxiliary lid 13 are in close contact with each other to form a space layer S.

Reference numeral 17 denotes an outer cover located above the auxiliary cover 13, which is composed of an upper plate 18, a lower plate 19, and a heat insulating material 20 interposed between them, and is pivotally supported on the frame 1 so as to be openable and closable. The steam guide tube 21 is equipped with a pressure device 22 in the center thereof, which is configured to press the center portion of the auxiliary lid 13 downward.

This pressure device 22 includes a pressure plate 24 having an elastic body 23 such as silicone rubber loosely fitted into the center of the lower plate 19;
It consists of a presser metal fitting 25 provided above the press plate 24 and a spring 26 that presses the presser metal fitting 25 downward.

27 is a frame cover that fixes the upper periphery of the frame 1 and the outer pot 2; 28 is a heater fixed to the upper surface of the lower plate 19; and 29 is a bundle integrally formed with the outer plate 18.

Next, to describe the function and effect, first, the through hole 14 of the auxiliary lid 13 is inserted into the knob 7 of the inner lid 4, and the hole 15 is penetrated into the shielding plate 9, and the protruding pin 16 is inserted into the play hole 12 of the inner lid 4.
Insert it inside.

In this case, the auxiliary lid 13 is prevented from rotating by the protruding pin 16, and the outer peripheral edges of the auxiliary lid 13 and the inner lid 4 are brought into close contact with each other. It is desirable to make the curling portion C2 of the auxiliary lid 13 detachable so that the fitted auxiliary lid 13 can be attached and detached.

Then, push the knob 7 of the inner lid 4 onto the elastic body 23 of the pressure device 22.
By fitting and inserting the auxiliary lid 13 into the inner pot 3, the spring 26 presses the auxiliary lid 13 through the pressing metal fitting 25 and the pressing plate 24, and transmits the pressure to the inner lid 4 at its outer periphery. Close it to 5.

At this time, the upper part of the shielding plate 9 is located in the steam guide cylinder 21 through the hole 15 of the auxiliary lid 13, and the upper end of the guide cylinder 9 is located below the lower surface of the auxiliary lid 13.

Therefore, when rice and water are stored in the inner pot 3 and a rice cooking switch (not shown) is operated, the steam generated due to the rice cooking operation rises in pressure inside the inner pot 3 and flows out of the guide cylinder 11. The relatively heavy sticky material that rises from the hole 10 as indicated by the arrow in FIG.

In addition, the steam containing soot that has risen vigorously hits the upper end of the shielding plate 9, and the heavy soot is scattered and accumulates at the upper part of the inner lid 4, while the relatively light steam hits the shielding plate 9 and the inner lid of the shielding plate. The auxiliary lid 13 is
The steam flows upward, rises further, and is discharged to the outside through the steam guide tube 21.

That is, the guide cylinder 11 attached to the inner lid 4 and the shielding plate 9 completely separate the sticky substance and steam.

When the rice cooking operation is finished and the pressure inside the inner pot 3 decreases, the rice cake accumulated on the top surface of the inner lid 4 is returned to the inner pot 3 through the small hole 8, and the nutrients fall onto the plate. .

As described above, the present invention stores an inner pot in an outer pot housed in a frame, and provides a shielding plate with a guide cylinder inside the inner lid that opens and closes the opening of the inner pot, and the upper surface of the inner lid An auxiliary lid is placed on the auxiliary lid, and the shielding plate is penetrated above the auxiliary lid to form a space layer between the auxiliary lid and the inner lid, and the steam in the inner pot is applied to the shielding plate through the guide cylinder. Since it separates relatively light steam and soot, the separation of steam and soot is more reliable than in the conventional case where the steam is discharged to the outside air through a small hole in the inner lid and a space layer.

That is, since all the steam in the inner pot hits the shielding plate through the guide cylinder, the separation effect such as the steam passage being blocked by air bubbles generated on the upper surface of the small hole is not reduced by half.

In addition, since the shielding plate is penetrated by the auxiliary lid, the light (separated) steam flows back into the space layer and immediately flows out above the auxiliary lid without suppressing the waste flowing out from the guide tube. In addition, since the shielding plate and the guide tube are each provided on the inner cover, their mutual dimensional relationship is always constant even if the inner cover is removed.

The lid is equipped with a guide cylinder and a shielding plate dedicated to releasing steam from the inner pot, as well as multiple small holes for returning rice, so the small holes are blocked by rice during the cooking process. In addition to this, the steam release is effective, and its operation is more reliable than the conventional small hole which serves both as a steam escape and a return of steam.

The bulging part of the inner cover is to make it easier to pull the knob downward when attaching the inner cover to the outer cover, and also to collect the slime to the small hole side, and the steam passing through the guide cylinder is relatively heavy. Therefore, there is no possibility of forming a sticky film on the upper opening end surface of the guide tube.

Furthermore, the space layer formed by the auxiliary lid and the inner lid is for storing steam and prevents the scum from falling suddenly when the outer lid is opened and closed, and the auxiliary lid prevents steam from adhering to the inner wall surface of the outer lid. .
