【産業上の利用分野】本発明は圧力をかけて炊飯や煮物
等の調理を行う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 for cooking rice or boiled food by applying pressure.
【０００２】[0002]
【従来の技術】水と米を収容した鍋内の圧力を高めて美
味しい御飯を炊くことや調理することは古くから知られ
ている。2. Description of the Related Art It has long been known to cook and cook delicious rice by increasing the pressure in a pot containing water and rice.
【０００３】炊飯器の場合には、前述の圧力は大気圧以
上の例えば１.１Ｋｇｆ／ｃｍ2の圧力で炊飯を行うと，
特に美味しい御飯になることが解明されている。In the case of a rice cooker, if the rice is cooked at a pressure higher than the atmospheric pressure, for example, at a pressure of 1.1 kgf / cm 2 ,
It has been elucidated that it will be particularly delicious.
【０００４】この様な先行技術として本出願人による出
願の特開平６−４６９５６号公報を提示する。As such prior art, Japanese Patent Application Laid-Open No. 6-46956 filed by the present applicant is presented.
【０００５】そして、圧力炊飯や圧力調理を行うと鍋内

保持する所謂、圧力調整弁と、この圧力調整弁が異物に
より詰まった場合における鍋内の高圧時に鍋内と大気と
を連通して圧力を抜く圧力安全弁を設けている。[0005] Since pressure inside the pot becomes high when pressure cooking or pressure cooking is performed, a pressure responsive valve is provided on a lid that covers the opening of the pot. This pressure responsive valve is a so-called pressure regulating valve that opens when the inside of the pot is at a predetermined pressure or higher and communicates with the inside of the pot and the atmosphere to maintain a predetermined pressure value. A pressure relief valve is provided to release pressure by communicating between the inside of the pot and the atmosphere when the pot is at high pressure.
【０００６】ところが、前述の先行技術の場合でも、他
の圧力式調理器の場合でも同様であるが、圧力を高めて
炊飯を行う場合には鍋は勿論のこと、この鍋の開口部を
密閉する蓋にも大きな圧力が加わり、この蓋が押し上げ
られて開放する様な力が働くことになる。[0006] However, the same applies to the case of the above-mentioned prior art and other pressure cookers, but when cooking rice by increasing the pressure, not only the pot but also the opening of the pot is sealed. A large pressure is also applied to the lid, which acts as if the lid is pushed up and opened.

くいものとなった。As a result, a reinforcing plate made of an iron plate or the like is placed inside the lid to prevent the lid from being deformed or damaged, but the thickness of the reinforcing plate is reduced. If the thickness is thin, the reinforcing plate itself will be deformed and the lid will be deformed. Conversely, if the thickness of the reinforcing plate is increased, the deformation of the lid can be prevented, but the weight of the entire lid will be increased and the hinge portion and the locking device It was necessary to increase the strength of the material, and it became difficult to handle.
【０００８】本発明は、蓋体の重量を重くすることなく

This application example utilizes the fact that the locking plate (33) rotates from the state shown in FIG. 1 to the state shown in FIG. 4 with an increase in pressure, and a magnet (49) is attached to the locking plate (33). The normally open reed switch (50) is fixed to the lamp substrate (48).

A reinforcing plate disposed in the space of the lid, the reinforcing plate extending toward the hinge portion and a locking plate provided on a side opposite to the hinge portion, and having a parallel edge. Since the upper part has a horizontal piece bent horizontally to form a parallel bent piece bent upward, the strength of the reinforcing plate is sufficiently increased by the bent piece, and the lid body is formed by the pressure in the inner pot. The lifting force applied to the cover is prevented by the reinforcing plate. In particular, the bent piece serves as a reinforcing material for the entire lid to prevent deformation and breakage of the lid, and the horizontal piece serves as a strength for the entire locking plate, especially for the pivot portion. Enhance. For this reason, it is not necessary to increase the thickness of the reinforcing plate, and the weight of the lid can be increased, and the strength of the hinge portion and the lock device is prevented from being excessively increased.
Handling of opening / closing and cleaning of the lid is simplified.

装置の動作が正確となる。A pressure responsive valve is provided on the inner lid for covering the opening of the inner pot housed in the main body of the cooker to make the inner pot communicate with the atmosphere by an external operation. The pressure relief valve is operated by a pressure relief device, and since the pressure relief device is fixed between opposed bent pieces on the upper surface of the reinforcing plate, the pressure relief device has strength. The device is stably fixed to the reinforcing plate with the least deformation, and the operation of the device becomes accurate even if the pressure in the inner pot increases.
