【発明の属する技術分野】本発明は電気炊飯器のように
鍋内の圧力を高めて調理を実行する圧力調理器に関す
る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure cooker, such as an electric rice cooker, for performing cooking by increasing the pressure in a pot.
【０００２】[0002]
【従来の技術】鍋内の圧力を高くして炊飯や、煮物等の
調理を行うと短時間に、且つ美味しく炊き上り、出来上
がることが知られている。2. Description of the Related Art It is known that cooking rice, boiled food, and the like by increasing the pressure in a pot results in a short and delicious cooked food.

弁が設けられている。A pressure regulating valve for keeping the inside of the pot at a predetermined pressure and a valve which opens when the inside of the pot becomes abnormally high pressure to open and communicate the inside of the pot with the atmosphere. A safety valve is provided.

目参照）However, apart from the above-mentioned valve, Japanese Unexamined Patent Publication No.
As shown in Japanese Patent No. 6957, a switching valve for communicating the inside of the pot with the atmosphere by an external operation is provided. The original purpose of this switching valve is to switch between cooking rice at normal pressure and cooking rice at high pressure, as described in the description of the prior art. When the lid is opened during the pressure cooking, the switching button is pressed to release the pressure in the pan, and then the locking button is pressed to release the locked state of the lid. (See page 4, line 5, line 41 to line 6, column 4, line 4)
【０００６】[0006]
【発明が解決しようとする課題】この様に圧力調理器の
場合は、鍋内の圧力を大気中に逃がして常圧状態にしな
いと蓋の開放ができないが、蓋の開放は圧力調理中より
も保温中の場合が多い。As described above, in the case of the pressure cooker, the lid cannot be opened unless the pressure in the pot is released to the atmosphere and brought to a normal pressure state. Is also often kept warm.
【０００７】圧力調理器の様に圧力調理が終了した後で
は、自然には短時間に圧力が下がらないため、切替弁を
操作するわけであるが、この操作が面倒であった。[0007] After the pressure cooking is completed, as in a pressure cooker, the switching valve is operated because the pressure does not naturally decrease in a short time, but this operation is troublesome.
【０００８】特に調理終了後は蓋の開閉回数が多く、開
放の都度、切替弁を操作して鍋内の圧力を大気に逃がす
必要があり使い勝手の悪いものである。これは、圧力調
理器の場合は、蓋の構成が他の常圧調理器に比べて異な
ることから、仮に保温時のような調理終了後であっても
鍋の密閉度が高いからである。In particular, after cooking is completed, the lid is frequently opened and closed, and every time the lid is opened, it is necessary to operate the switching valve to release the pressure in the pot to the atmosphere, which is inconvenient. This is because, in the case of a pressure cooker, the lid configuration is different from that of other normal-pressure cookers, so that the degree of sealing of the pot is high even after the completion of cooking, such as during warming.
【０００９】従って、前記切替弁は調理終了後のように
必要な時に自動的に鍋内の圧力を逃がすような構成が望
ましいが、全ての使用状態を想定して自動的に圧力を逃
がすことは無理であり、このために切替弁は使用者の意
思に基づいて外部操作をすることができるようにする必
要がある。Therefore, it is desirable that the switching valve be configured to automatically release the pressure in the pot when necessary, for example, after the completion of cooking. However, it is not possible to automatically release the pressure in all usage states. It is not possible, and for this reason, the switching valve needs to be able to be operated externally based on the user's intention.
【００１０】この様な種々の要素を加味して鍋内の圧力
を最低限の必要な時に自動的に大気に逃がし、使用者が
必要な時に外部操作で圧力を逃がし、それぞれの機能を
有効に、且つ使い勝手をよくしたものはなかった。In consideration of such various factors, the pressure in the pot is automatically released to the atmosphere when required at a minimum, and the pressure is released by an external operation when the user needs it, so that each function is effectively performed. Nothing was more convenient.

れぞれの機構を共通化して簡素化し、さらに機構の作動
をスムースにしたものである。According to the present invention, the pressure in the pot is automatically released to the atmosphere at a minimum when necessary, and the pressure is released by an external operation as required to facilitate opening of the lid. The mechanism is shared and simplified, and the operation of the mechanism is smoothed.

鍋内の圧力を逃がして蓋体を開放することができる。As described above, the present invention relates to a pressure release button pivotally supported, and a pressure release button disposed below the pressure release button and located at a position opposite to the operation button that allows the cover to be opened. A rotatable operation plate provided with a pivot portion, a drive motor that operates after cooking is completed, and a slide plate that is moved by the drive motor to rotate the operation plate, wherein the pressure release button and the slide plate move to move the inside of the pan. Can be released to the atmosphere. That is, the pressure in the pot can be automatically released and the lid can be opened, depending on the user's intention and at the minimum necessary time.
