例である外蓋、29はハンドルで、上記外蓋28の下面
には放熱板30が固定され、外蓋28と放熱板30との
間の空間には断熱材31が充填されるとともに、放熱板
30の外周端部に設けたパツキン30 aが内なべ27
の上面に密着して内なべ27の内部を密閉している。Reference numeral 28 denotes an outer lid, which is an example of a lid that can be opened and closed with respect to the main body 21; 29, a handle; a heat sink 30 is fixed to the lower surface of the outer lid 28; The space between them is filled with a heat insulating material 31, and a gasket 30a provided at the outer peripheral end of the heat sink 30 is attached to the inner pan 27.
The inside of the inner pot 27 is sealed by closely contacting the upper surface of the inner pot 27.
放熱板30の中央には内蓋取付軸32が垂設されており
、この内蓋取付軸32にはゴム材からなる取付ブツシュ
33が摺動可能に嵌合しており、取付ブツシュ33のま
わりに内蓋34が気密性をもって取付けられている。An inner cover mounting shaft 32 is vertically installed in the center of the heat dissipation plate 30, and a mounting bush 33 made of a rubber material is slidably fitted to this inner cover mounting shaft 32. An inner cover 34 is airtightly attached to the inner cover 34.
内蓋34の外周端部は内なべ27の上面に圧接するよう
になっており、圧接時の反力により取付ブツシュ33は
上方に圧縮し、内蓋34の内なべ27への圧接力を適度
に調整している。The outer peripheral end of the inner lid 34 is brought into pressure contact with the upper surface of the inner pot 27, and the mounting bushing 33 is compressed upward by the reaction force at the time of pressure contact, and the pressure contact force of the inner lid 34 against the inner pot 27 is moderately applied. is being adjusted.
なお、35は内蓋34に設けられた蒸気孔である。Note that 35 is a steam hole provided in the inner lid 34.
外蓋28には上下に連通ずる通気孔36が設けられてお
り、この通気孔36に上記調圧装置1が取付けられてい
る。The outer cover 28 is provided with a ventilation hole 36 that communicates with the upper and lower sides, and the pressure regulating device 1 is attached to this ventilation hole 36.
すなわち、通気孔36には上面に蒸気口38を有する略
筒状の蒸気パイプ37が挿入され、蒸気パイプ37の下
端部はシールリング40を間にして放熱板30上に複数
本のビス41にて固定されており、上記シールリング4
0によって湿った空気が断熱材31を装填した外蓋28
の内部に侵入しないようになっている。That is, a substantially cylindrical steam pipe 37 having a steam port 38 on the upper surface is inserted into the ventilation hole 36, and the lower end of the steam pipe 37 is connected to a plurality of screws 41 on the heat sink 30 with a seal ring 40 in between. The above seal ring 4
The outer lid 28 loaded with the heat insulating material 31
It is designed to prevent it from entering inside.
蒸気パイプ37の下端部内側面には雌ねじ39が設けら
れており、この雌ねじ39に取付具2の筒部外側面に設
けた雄ねじ8を取付具2の把持部3を持って螺合させる
ことにより、調圧装置1は蒸気パイプ37に取付けられ
る。A female thread 39 is provided on the inner surface of the lower end of the steam pipe 37, and by screwing the male thread 8 provided on the outer surface of the cylindrical portion of the fixture 2 into this female thread 39 by holding the grip portion 3 of the fixture 2, , the pressure regulating device 1 is attached to the steam pipe 37.
そして、シールリング40の内端部下面が取付具2の把
持部3上面に圧接し、上記雌ねじ39と雄ねじ8との螺
合部から外部への空気漏れを完全になくすことができる
。The lower surface of the inner end of the seal ring 40 comes into pressure contact with the upper surface of the grip portion 3 of the fixture 2, and air leakage to the outside from the threaded portion between the female thread 39 and the male thread 8 can be completely eliminated.
外蓋28を閉鎖した状態においては、内蓋34の外周端
部が内なべ27の上面に圧接しているため、その反力で
取付ブツシュ33は上方に押し上げられている。When the outer lid 28 is closed, the outer circumferential end of the inner lid 34 is in pressure contact with the upper surface of the inner pot 27, so that the mounting bush 33 is pushed upward by the reaction force.
そして、調圧装置1のボール15はブツシュ9の弁座部
11上に載置されており、排気孔10は閉鎖されている
。The ball 15 of the pressure regulator 1 is placed on the valve seat 11 of the bush 9, and the exhaust hole 10 is closed.
いま、炊飯ヒータ25へ通電すると、内なべ27内は放
熱板30のパツキン30 aにより密閉されているため
、効率よく炊飯が行なわれる。Now, when electricity is supplied to the rice cooking heater 25, the inside of the inner pot 27 is sealed by the gasket 30a of the heat sink 30, so that rice is efficiently cooked.
途中で内なべ27内の蒸気圧が所定圧以上に上昇したと
きには、その蒸気圧によって調圧装置1のボール15が
弁座部11から若干浮き上り、内なべ27内の蒸気は内
蓋34の蒸気孔35、調圧装置1の排気孔10および蒸
気パイプ37の蒸気口38を介して外部に排気され、内
なべ27内の蒸気圧は過度に上昇する心配がない。When the steam pressure in the inner pot 27 rises to a predetermined pressure or higher on the way, the ball 15 of the pressure regulator 1 rises slightly from the valve seat 11 due to the steam pressure, and the steam in the inner pot 27 rises above the inner lid 34. The steam is exhausted to the outside through the steam hole 35, the exhaust hole 10 of the pressure regulator 1, and the steam port 38 of the steam pipe 37, so there is no fear that the steam pressure in the inner pot 27 will rise excessively.
上記蒸気圧の調整はボール15の重量によって行なうこ
とができ、たとえば排気孔10の直径を6mmとし、ボ
ール15として直径lQmmのステンレス鋼球を用いた
場合には、蒸気圧が水柱200 mmとなったときにボ
ール15が動作する。The above steam pressure can be adjusted by the weight of the ball 15. For example, if the diameter of the exhaust hole 10 is 6 mm and the ball 15 is a stainless steel ball with a diameter of 1Q mm, the steam pressure will be 200 mm of water column. When the ball 15 moves, the ball 15 moves.
また、飯が炊き上った状態で長時間放置しておくと、内
なべ27内は自然冷却し、温度低下とともに内なべ27
内は負圧となり、外蓋28は炊飯ジャ一本体21に対し
て容易に開くことができなくなる。Additionally, if the cooked rice is left for a long time, the inside of the inner pot 27 will naturally cool down, and as the temperature drops, the inner pot 27 will cool down naturally.
The pressure inside becomes negative, and the outer lid 28 cannot be easily opened relative to the rice cooker main body 21.
ところが、この負圧が所定圧(例えば水柱20mm)以
上になったとき、ブツシュ9の弁体12が下方に撓んで
吸気孔5を開き、外気を内なべ27内に取り入れるため
、内なべ27内の負圧は解消され、外蓋28を容易に開
くことができる。However, when this negative pressure exceeds a predetermined pressure (for example, 20 mm of water column), the valve body 12 of the bushing 9 bends downward to open the intake hole 5 and take outside air into the inner pot 27. The negative pressure is eliminated, and the outer cover 28 can be opened easily.

気パイプ37の内側面に圧接する。In the above embodiment, a male thread 8 is provided on the outer surface of the cylindrical portion of the fixture 2, and a female thread 39 is provided on the inner surface of the steam pipe 37, and the pressure regulator 1 is attached to the vent hole 36 by screwing these together. However, the present invention is not limited to this, and as shown in FIG. By providing the protrusion 43 and forcing the fitting 2 into the steam pipe 37 from below, the small sea member 42 rides over the protrusion 43 with its own elasticity and comes into pressure contact with the inner surface of the steam pipe 37.
これによって、調圧装置1は空気漏れなく取付けられる
。Thereby, the pressure regulator 1 can be installed without air leakage.
なお、第5図中、第4図と同一部品には同一番号を付し
て説明を省略する。In FIG. 5, parts that are the same as those in FIG. 4 are given the same numbers and their explanations will be omitted.
また、調圧装置1は外蓋28ばかりでなく、調理器本体
の側壁に通気孔を設けた場合には、この通気孔に調圧装
置を取付ければよい。Moreover, when the pressure regulating device 1 is provided with a vent hole not only in the outer lid 28 but also in the side wall of the cooking device main body, the pressure regulating device may be attached to this vent hole.
以上のように、本考案によれば調圧装置を蓋体あるいは
側壁に設けた通気孔に取付けることにより、調理器内部
の圧力を容易に調整することができる。As described above, according to the present invention, the pressure inside the cooking appliance can be easily adjusted by attaching the pressure regulating device to the vent provided in the lid or the side wall.
すなわち、ボールの重量により調理器内の正圧を調整し
、ブツシュの弁体の弾性力により調理器内の負圧を調整
することができる。That is, the positive pressure inside the cooking device can be adjusted by the weight of the ball, and the negative pressure inside the cooking device can be adjusted by the elastic force of the valve body of the bush.
しかも、調圧装置は取付具にブツシュとボールとボール
キャップとを一体に組込んであるので、運搬時等におい
て部品を紛失することなく取扱いが極めて容易となり、
また調圧装置が汚れたときでも、調圧装置を通気孔から
適宜取外して洗浄することができる。Moreover, since the pressure regulating device has the bushing, ball, and ball cap integrated into the mounting fixture, it is extremely easy to handle without losing any parts during transportation.
Further, even when the pressure regulating device becomes dirty, the pressure regulating device can be removed from the vent hole and washed.
