いものとなってしまう。2. Description of the Prior Art The lid of a gas rice cooker is shown in FIG.
As shown in FIG. 2, a connecting shaft (13), which is composed of an upper lid (11) and a dish-shaped inner lid (12) and is provided at the center of the lower surface of the upper lid (11), is attached to the inner lid (12). The knob bearing (14) formed at the center is integrated with the knob bearing (14), and through holes (6) and (6) are formed in the vicinity of the knob bearing (14). Further, as the structure of the conventional rice cooker, as shown in FIG. 3, the heat insulating layer (3) provided in the tubular inner body is housed in the outer case (2),
The rice cooker (20) is removably housed in the heat insulating layer (3), and the intake air to the combustion chamber below the rice cooker (20) is introduced from below the exterior case (2) to the exterior. It reaches the upper part of the front of the case, and from this part it descends along the outer surface of the heat retaining layer (3) to reach the combustion chamber, and exhausts between the rice cooker (20) and the inner wall (30) of the heat retaining layer. The inner peripheral wall (30) of the heat retaining layer (3) or the brim portion of the rice cooker (20), which is configured as a passage (22) and projects upward by a predetermined height from the upper end of the heat retaining layer (3). (K) has a structure in which the outlet of the exhaust passage (22) is opened to either of the top plate (35) which is continuously provided on the upper end of the inner peripheral wall (30). is there. Above the exterior case (2), the lid body is pivotally supported at its rear end portion to the rear end portion of the exterior case (2) so that it can be opened forward. The inner lid (12) constituting the lid body closes the upper part of the rice cooker (20) in a hermetically sealed state. Then, the steam generated in the rice cooker during the rice cooking is fed from the through holes (6) (6) formed in the inner lid (12) to the upper lid (11) and the inner lid (1) as shown in FIG.
The steam that has escaped to the space (S) with 2) and that has escaped to this space (S) is exhausted to the outside from the steam vent (60) formed at the upper end of the upper lid (11). Will be done. The upper open part of the rice cooker (20) is closed by the inner lid (12) as described above, but the steam that has escaped to the space between the upper lid (11) and the inner lid (12) is However, there is an inconvenience of leaking out from the peripheral portion of the space. If the steam leaks out from the peripheral portion of the space, it will be left as dew on the peripheral portion of the upper lid (11) and will be unsightly.

がある。Therefore, conventionally, as shown in FIG. 2, the rice cooker (20) is cooked so that the upper end of the brim (K) and the lower surface of the upper lid (11) are reliably sealed. Kettle (20)
An annular packing seal (1) made of an elastic material was provided in a predetermined area of the lower surface of the upper lid (11) facing the upper end of the. As a result, the vapor in the space between the upper lid (11) and the inner lid (12) will not be leaked from the peripheral portion of the upper lid (11) and will be exhausted to the outside from the vapor venting portion (60) of the upper lid (11). Become. However, with this structure,
Since the outlet of the exhaust passage (22) coincides with the vicinity of the upper edge of the rice cooker (20), that is, the position where the packing seal (1) is arranged, the packing seal (1) is overheated by combustion exhaust. . Since the packing seal (1) is made of an elastic material as described above, it is easily damaged when overheated, and if the packing seal (1) is damaged, reliable sealing performance cannot be expected. There is the inconvenience that steam leaks to the outside from the peripheral edge of the upper lid (11).

The rice cooker body used in the embodiment of the present invention may have the same structure as the conventional one, and the rice cooker (20) is provided with a substantially L-shaped brim (K) at the upper peripheral edge. Cage,
A top plate (3) provided with the brim (K) on the upper end of the inner peripheral wall (30) of the heat retaining layer (3) housed in the outer case (2).
The rice cooker (20) is removably accommodated in the heat retaining layer (3) by being locked to the heat retaining layer (3), and an exhaust passage (22) is provided between the heat retaining layer (3) and the rice cooker (20). In particular, in this embodiment, as shown in FIG. 1, the inner peripheral wall (3) formed higher than the heat retaining layer (3) is formed.
The structure in which the outlet of the exhaust passage (22) is provided in 0) is adopted. As the inner lid (12), the same one as the conventional one can be adopted, and the vicinity of its peripheral portion is in the shape of a dish protruding upward from its central portion, and the peripheral portion is the rice cooker (20). ), The upper opening of the rice cooker (20) is closed. That is, the upper end of the brim (K) has the inner lid (1
It will be located further outside than the peripheral portion of 2).

によって気密状態にシールされることとなる。The packing seal (1) used in this embodiment is an annular body made of an elastic material and having a substantially ⊂-shaped cross section. The height of the packing seal (1) is the upper surface of the peripheral portion of the inner lid (12) and the upper lid facing the upper surface. It is set to be slightly larger than the height between the lower surface of (11). The packing seal (1) is attached to the lower surface of the upper lid (11) by an annular pressing plate (15) screwed to the lower surface of the upper lid (11) facing the vicinity of the peripheral edge of the inner lid (12). Between the pressing plate (15) and the mounting piece (10) of the packing seal (1),
It is attached by pressing it all over. Then, in a state where the connecting shaft (13) of the upper lid (11) is fitted to the knob bearing (14) of the inner lid (12), the lower surface of the packing seal (1) is a peripheral edge of the inner lid (12). It comes into contact with the upper surface in the vicinity of the portion and the elastic force presses it slightly downward. When the lid body is closed in the rice cooker body in this state, the peripheral edge portion of the inner lid (12) is attached to the brim portion (K) of the rice cooker (20) by the packing seal (1) as shown in FIG. While being pressed down, the packing seal (1) is sandwiched between the lower surface of the upper lid (11) and the upper surface of the inner lid (12) while being slightly elastically deformed. As a result, the upper opening of the rice cooker (20) is reliably sealed by the inner lid (12) and the packing seal (1) is also provided between the inner lid (12) and the upper lid (11).
Will be hermetically sealed.

Since the air is exhausted from the outlet formed in the inner peripheral wall (30) of the heat retaining layer (3), the upper region of the rice cooker body is easily overheated, but the packing seal (1) of this embodiment is The combustion exhaust does not directly affect the packing seal (1) because it is provided inward of the upper end of the flange (K) of 20). In this embodiment, the outlet of the exhaust passage (22) is formed in the inner peripheral wall (30), but the same effect can be expected when the outlet is formed in the top plate (35). Further, a weight (17) for adjusting the pressure inside the rice cooker (20) is externally fitted to the knob bearing (14) so as to be able to move up and down, which opens the through holes (6) and (6) due to an increase in the internal pressure. Then, the steam and the steam are discharged into the space (S).
