圧するようにしている。2. Description of the Related Art As shown in FIG. 4, a lid A of a rice cooker has an inner lid 3 removably attached via a packing 4 to a mounting projection 2 provided at the center of the inner surface of the lid main body 1. Packing 4
Is composed of a seal portion 6 that is in close contact with the projection 2 and the mounting hole 5 of the inner lid 3, and a bowl-shaped elastic portion 7. The upper end of the elastic portion 7 is pressed against the inner surface of the lid body 1. By doing
The peripheral edge of the inner lid 3 is elastically pressed against the flange 9 of the pot 8.
【０００３】このため、内蓋３は中央の取付け部分にお

【発明が解決しようとする課題】上記のごとき炊飯器に
おいて、鍋８を炊飯器本体１１に収納する際、使用者は
時に鍋８を傾けたまま収納することがある。この場合、
鍋８自体が熱板１２に沿って滑ることにより正常な姿勢
に戻ることもあるが、鍋８の外周面が粗面であったり、
熱板１２が粗面であったりすると滑り難いことがあり、
必ずしも勝手に正常な姿勢に戻ることを期待できない場
合もある。鍋８が傾いたまま収納したことに使用者が気
付かずに蓋を閉めると、その鍋８に前記の内蓋３は接触
するが、前述のように内蓋３はパッキン４を介して柔軟
に取付けられているので、その内蓋３は鍋８の傾きに応
じて傾くだけであり、その鍋８の姿勢を修正する作用は
生じない。In the rice cooker as described above, when the pan 8 is stored in the rice cooker main body 11, the user sometimes stores the pan 8 with the pan 8 tilted. in this case,
The pot 8 itself may return to a normal position by sliding along the hot plate 12, but the outer peripheral surface of the pot 8 may be rough,
If the hot plate 12 is rough, it may be difficult to slip,
In some cases, it is not always possible to expect to return to a normal posture without permission. When the user closes the lid without noticing that the pot 8 is stored while being tilted, the inner lid 3 comes into contact with the pot 8, but the inner lid 3 is softened via the packing 4 as described above. Since it is attached, its inner lid 3 only tilts in accordance with the tilt of the pot 8, and no action is taken to correct the attitude of the pot 8.
【０００５】このようにして、鍋８が傾いたまま炊飯を
行うと、加熱板方式の炊飯器においては加熱板と鍋８と
の接触状態が悪くなり、加熱板の異常発熱や、各部温度
の異常の原因となる。またＩＨ方式の炊飯器において
は、磁界分布に異常を来たし、炊きムラの原因となる。[0005] When rice is cooked while the pan 8 is tilted in this manner, in a rice cooker of the heating plate type, the contact state between the heating plate and the pan 8 is deteriorated, causing abnormal heating of the heating plate and the temperature of each part. Failure to do so may result. In addition, in the IH rice cooker, the magnetic field distribution becomes abnormal, which causes uneven cooking.
【０００６】上記のごとき問題を解消するために、蓋本
体１の内面に内蓋３上面に当たる規制突起１３（図４の
２点鎖線参照）を該内蓋３外周縁の内側に沿って設ける
ことが考えられる。In order to solve the above problem, a regulating projection 13 (see a two-dot chain line in FIG. 4) is provided on the inner surface of the lid main body 1 so as to contact the upper surface of the inner lid 3 along the outer peripheral edge of the inner lid 3. Can be considered.
【０００７】しかし、この方法によると、傾いた鍋８の
フランジ９に内蓋３が強制的に押し当てられるので、剛
性の小さいアルミ板製の内蓋３が変形する可能性があ
る。However, according to this method, since the inner lid 3 is forcibly pressed against the flange 9 of the inclined pot 8, the inner lid 3 made of a rigid aluminum plate may be deformed.
【０００８】また、内蓋３を洗浄等の必要のために取外

蓋３を外し難いという問題が生じる。When removing the inner lid 3 for the necessity of cleaning or the like, a fingertip is hung on a part of the outer peripheral edge of the inner lid 3 and the part is tilted and removed. However, if the regulating projection 13 contacts the inside of the outer peripheral edge of the inner lid 3 as described above, it is difficult to cause the obliquely, and there is a problem that it is difficult to remove the inner lid 3.
【０００９】そこで、この発明はたとえ鍋８が傾いたま
ま収納されたとしても、内蓋３自体に又はその取外しに
支障を来たすことなく、蓋を閉めることにより鍋８の傾
きを修正できるようにすることを目的とする。Therefore, the present invention is designed to correct the inclination of the pot 8 by closing the pot 8 without obstructing the inner lid 3 itself or its removal even if the pan 8 is stored while being tilted. The purpose is to do.

, Set the packing in the mounting hole provided in the inner lid,
The sealing part of the packing is tightly fitted to the projection.
Detachably attached to the inner lid in the lid body by, the package
Press the elastic part of the kin against the inner surface of the lid body, and
Of the pan supported by placing the part directly on the hot plate of the rice cooker body
The inner lid and the inner surface of the lid body.
In the lid of the rice cooker that forms the required gap between ,
A regulating projection is provided on the inner surface of the lid body outside the inner lid and along the outer periphery of the inner lid, and the regulating projection is located above a flange of the pan.

ｇ（図２参照）が生じる程度に設定するのが望ましい。However, in the case of the present invention, unlike the case of the prior art, a regulating projection 13 'is provided on the inner surface of the lid body 1 outside the inner lid 3 and along the outer periphery of the inner lid 3. . The height of the regulation protrusion 13 ′ is determined by the heating plate 12 of the rice cooker main body 11.
The height is set to the height located above the flange 9 of the pan 8 when the pan 8 is stored in a normal posture in the pan storage section 19 composed of the above. However, it is desirable to set the gap g (see FIG. 2) of about 0.8 mm to such an extent that a production error is considered.

れ、蓋Ａが完全に閉まると鍋８は正常な姿勢になる。The lid of the rice cooker according to the embodiment is as described above. When the user stores the pot 8 at an angle as described above, the position of the pot 8 is not corrected by the action of the pot 8 itself. If the user closes the lid without noticing the fact, the regulating protrusion 13 'of the lid body 1 hits a part of the flange 9 of the inner lid 3 and gives a strong pressing force to the pot 8 at that part. The position of the pot 8 is gradually corrected as the lid A is closed, and when the lid A is completely closed, the pot 8 is in a normal position.

望ましい。When the inner lid 3 is detached, the inner lid 3 is restricted by the restricting projection 1 even if the inner lid 3 is lifted by hooking a fingertip on a part of the outer peripheral edge thereof.
You can tilt freely because there is no interference with 3 '
Can be easily removed. In this case, it is desirable to disperse the regulating projections 13 ′ so that the fingertip can be easily hooked.
