従来、特許文献１のように、内圧を所定の気圧未満に保つ調圧装置を備えた圧力鍋が提案されている。 Conventionally, as in Patent Document 1, there has been proposed a pressure cooker equipped with a pressure regulating device that keeps the internal pressure below a predetermined atmospheric pressure.

特開２０１１－０５６１４２号公報JP 2011-056142 A

しかし、圧力鍋が略密閉されるため、加熱を止めた後、圧力鍋の内圧を下げて、圧力鍋蓋を鍋本体から取り外すことが出来るようになるまでに時間がかかっていた。 However, since the pressure cooker is substantially sealed, it takes time to reduce the internal pressure of the pressure cooker and remove the pressure cooker lid from the pot body after heating is stopped.

したがって本発明の目的は、加熱を止めた後、早期に圧力鍋蓋を鍋本体から取り外すことが出来る圧力鍋蓋などを提供することである。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pressure cooker lid, etc., which can be quickly removed from the pot body after heating is stopped.

本発明に係る圧力鍋蓋は、ノズルと、錘とを有し、内圧が第１気圧以上の時にノズルと錘の間から蒸気を排出する調圧装置と、ノズルが取り付けられた蓋本体とを備える。調圧装置と蓋本体の少なくとも一方には、第１気圧未満の時に蒸気を排出する蒸気排出領域が形成される。 A pressure cooker lid according to the present invention has a nozzle and a weight, and includes a pressure regulator that discharges steam from between the nozzle and the weight when the internal pressure is equal to or higher than a first atmospheric pressure, and a lid body to which the nozzle is attached. Prepare. At least one of the pressure regulating device and the lid body is formed with a steam discharge area for discharging steam when the pressure is less than the first atmospheric pressure.

圧力鍋の内圧に関わらず、また、つまみを操作することなく、蒸気排出領域を介して、圧力鍋の内部の蒸気を排出させることが出来る。
このため、蒸気排出領域を設けない形態に比べて、加熱を止めた後、圧力鍋の内圧を下げて、圧力鍋蓋を鍋本体から取り外すことが出来るようになるまでの時間を、短くすることが可能になる。
圧力鍋蓋を鍋本体から取り外すことが出来るようになるまでの時間を短くすることで、煮込み過ぎを防ぎ、所望の時間で調理を行うことが容易になる。 Regardless of the internal pressure of the pressure cooker, the steam inside the pressure cooker can be discharged through the steam discharge area without operating the knob.
For this reason, compared to a form without a steam discharge area, after stopping heating, the internal pressure of the pressure cooker is lowered, and the time until the pressure cooker lid can be removed from the pot body can be shortened. becomes possible.
By shortening the time until the lid of the pressure cooker can be removed from the pot body, overcooking can be prevented and cooking can be easily performed within a desired time.

好ましくは、錘は、ノズルと接する接続部材を有する。接続部材には、蒸気排出領域を形成するための第１切り欠きが設けられる。 Preferably, the weight has a connecting member that contacts the nozzle. The connecting member is provided with a first notch for forming a vapor discharge area.

第１切り欠きを設けた接続部材を用意するだけで、蒸気排出領域を形成出来る。このため、圧力鍋蓋の接続部材以外の部材を流用して、本発明の圧力鍋蓋を用意することが出来る。 The vapor discharge area can be formed only by preparing the connection member provided with the first notch. Therefore, the pressure cooker lid of the present invention can be prepared by using members other than the connection member of the pressure cooker lid.

さらに好ましくは、接続部材は、ねじ部とニードル部とを有する。ねじ部とニードル部に、第１切り欠きが設けられる。 More preferably, the connecting member has a threaded portion and a needle portion. A first notch is provided in the threaded portion and the needle portion.

ニードル部だけでなく、ねじ部にまで第１切り欠きが設けられる。このため、ニードル部にだけ第１切り欠きが設けられる形態に比べて、ねじ部の外形寸法を確認しながら、容易に所望の切り欠き量を有する第１切り欠きを形成することが出来る。 A first notch is provided not only on the needle portion but also on the threaded portion. Therefore, compared to a configuration in which the first notch is provided only in the needle portion, it is possible to easily form the first notch having a desired notch amount while confirming the outer dimensions of the threaded portion.

さらに好ましくは、接続部材として、第１の接続部材と、第１の接続部材の第１切り欠きよりも切り欠き量が多い第１切り欠きを有する第２の接続部材が設けられる。 More preferably, as the connection members, a first connection member and a second connection member having a first cutout having a larger cutout amount than the first cutout of the first connection member are provided.

この場合には、用途に応じて、複数の接続部材のいずれかを選択して使用することが可能になる。 In this case, it becomes possible to select and use any one of the plurality of connection members according to the application.

また、好ましくは、ノズルには、蒸気排出領域を形成するための第２切り欠きが設けられる。 Also preferably, the nozzle is provided with a second cutout for forming a vapor discharge area.

また、好ましくは、蓋本体とノズルの少なくとも一方には、蒸気排出領域を形成するための貫通孔が設けられる。 Moreover, preferably, at least one of the lid body and the nozzle is provided with a through hole for forming a steam discharge area.

さらに好ましくは、蒸気排出領域の開口面積は、ノズルにおける錘と対向する領域の開口部の開口面積よりも小さい。 More preferably, the opening area of the steam discharge region is smaller than the opening area of the opening of the region facing the weight in the nozzle.

また、好ましくは、圧力鍋蓋は、錘の上部を空けた状態で、錘の側部の少なくとも一部を囲む蒸気受け部を更に備える。蒸気排出領域は、ノズルと錘の少なくとも一方に設けられる。ノズルと錘の間から排出された蒸気が、蒸気受け部と蓋本体の間から外部に排出されるように、蒸気受け部と蓋本体の間には、蒸気誘導領域が形成される。 Moreover, preferably, the pressure cooker lid further includes a steam receiver surrounding at least a portion of the side portion of the weight with the upper portion of the weight left open. A vapor discharge area is provided in at least one of the nozzle and the weight. A steam guiding region is formed between the steam receiving part and the lid body so that the steam discharged from between the nozzle and the weight is discharged to the outside from between the steam receiving part and the lid body.

蒸気は、蒸気受け部と蓋本体の間から排出されるため、錘と蒸気受け部の間からは殆ど排出されない。
このため、つまみなどを介して錘を操作する使用者に蒸気が当たりにくく出来る。
また、蒸気誘導領域を通過する際に、蒸気の発生音の音質を変えることが出来る。
蒸気排出領域の形状、及び蒸気受け部と蓋本体の隙間の形状などを変えることにより、上記の発生音の音質を調整することも出来る。
このため、蒸気受け部を設けない形態に比べて、音量を下げたり、音質を変えたりした状態で、蒸気を排出することが可能になる。 Since the steam is discharged from between the steam receiving portion and the lid body, it is hardly discharged from between the weight and the steam receiving portion.
For this reason, it is possible to prevent steam from hitting the user who operates the weight via a knob or the like.
In addition, when passing through the steam induction area, the sound quality of the sound generated by the steam can be changed.
By changing the shape of the steam discharge region and the shape of the gap between the steam receiver and the lid body, the sound quality of the generated sound can be adjusted.
Therefore, steam can be discharged while the volume is lowered or the sound quality is changed, compared to a form in which no steam receiving portion is provided.

また、蒸気受け部は、錘の上部を覆わないので、錘が外部から見える状態が維持され、錘の上部が蒸気受け部などによって覆われる形態に比べて、錘の状態が視認しやすくなる。 In addition, since the steam receiving part does not cover the upper part of the weight, the weight is kept visible from the outside, and the state of the weight is easier to visually recognize than when the upper part of the weight is covered with the steam receiving part or the like.

本発明に係る圧力鍋は、ノズルと、錘とを有し、内圧が第１気圧以上の時にノズルと錘の間から蒸気を排出する調圧装置と、ノズルが取り付けられた蓋本体と、蓋本体が着脱可能な状態で取り付けられる鍋本体とを備える。調圧装置と蓋本体の少なくとも一方には、第１気圧未満の時に蒸気を排出する蒸気排出領域が形成される。 A pressure cooker according to the present invention has a nozzle and a weight, a pressure regulator that discharges steam from between the nozzle and the weight when the internal pressure is equal to or higher than a first atmospheric pressure, a lid body to which the nozzle is attached, and a lid. A pot main body to which the main body is attached in a detachable state is provided. At least one of the pressure regulating device and the lid body is formed with a steam discharge area for discharging steam when the pressure is less than the first atmospheric pressure.

以上のように本発明によれば、加熱を止めた後、早期に圧力鍋蓋を鍋本体から取り外すことが出来る圧力鍋蓋などを提供することができる。 As described above, according to the present invention, it is possible to provide a pressure cooker lid that can be quickly removed from the pot body after heating is stopped.

However, the connection member 35b having the first notch 35b3 may be formed by a method other than cutting.
For example, a configuration in which the threaded portion 35b1 including the first notch 35b3 and the needle portion 35b2 are formed by a mold is conceivable.

圧力鍋の内圧が第１気圧Ｐ１以上の場合は、圧力鍋の内部の圧力が錘３５（錘本体３５ａが取り付けられた接続部材３５ｂの下端部）を押し上げ、圧力鍋の内部の蒸気が、ノズルフィルター３１を介し、ノズル３３と錘３５（錘本体３５ａが取り付けられた接続部材３５ｂの下端部）の間から排出される（図７参照）。
圧力鍋の内圧が第１気圧Ｐ１未満の場合は、錘３５（錘本体３５ａが取り付けられた接続部材３５ｂの下端部）がノズル３３の先端の間の領域の一部を閉じるため、ここから圧力鍋の内部の蒸気は殆ど排出されない（図６参照）。
ただし、接続部材３５ｂに第１切り欠き３５ｂ３によって、接続部材３５ｂの下端部とノズル３３の先端の間の領域の残り部分（蒸気排出領域）が開口するので、ここから圧力鍋の内部の蒸気が排出される。
錘本体３５ａの重さと第１切り欠き３５ｂ３で形成される蒸気排出領域の大きさの少なくとも一方を変えることにより、第１気圧Ｐ１が調整される。 When the internal pressure of the pressure cooker is equal to or higher than the first atmospheric pressure P1, the pressure inside the pressure cooker pushes up the weight 35 (the lower end of the connection member 35b to which the weight body 35a is attached), and the steam inside the pressure cooker is released into the nozzle. It is discharged from between the nozzle 33 and the weight 35 (the lower end of the connection member 35b to which the weight body 35a is attached) through the filter 31 (see FIG. 7).
When the internal pressure of the pressure cooker is less than the first atmospheric pressure P1, the weight 35 (the lower end of the connection member 35b to which the weight body 35a is attached) closes a part of the region between the tips of the nozzles 33. Almost no steam inside the pan is discharged (see Figure 6).
However, the first notch 35b3 in the connecting member 35b opens the remaining portion (steam discharge region) of the region between the lower end of the connecting member 35b and the tip of the nozzle 33, so the steam inside the pressure cooker is discharged from here. Ejected.
The first air pressure P1 is adjusted by changing at least one of the weight of the weight body 35a and the size of the steam discharge area formed by the first notch 35b3.

錘３５を構成する錘本体３５ａと接続部材３５ｂは、別体構成であってもよいし、一体的に形成される形態であってもよい。 The weight main body 35a and the connection member 35b that constitute the weight 35 may be configured separately or integrally.

（つまみ３７）
つまみ３７は、シリコンゴムなどで構成され、接続部材３５ｂの上部を覆う。
つまみ３７を上下方向に動かすことで、錘３５（錘本体３５ａと接続部材３５ｂ）が上下方向に移動し、これにより、ノズル３３と錘３５の距離が変動し、ノズル３３と錘３５の間から、圧力鍋の内部の蒸気を排出させることが出来る（図７参照）。
第１実施形態では、つまみ３７が接続部材３５ｂと別体で構成される形態を説明するが、一体的に構成される形態であってもよい。 (Knob 37)
The knob 37 is made of silicone rubber or the like, and covers the upper portion of the connection member 35b.
By moving the knob 37 in the vertical direction, the weight 35 (the weight body 35a and the connection member 35b) is moved in the vertical direction, thereby changing the distance between the nozzle 33 and the weight 35, and the pressure from between the nozzle 33 and the weight 35 is changed. , the steam inside the pressure cooker can be discharged (see Fig. 7).
In the first embodiment, a mode in which the knob 37 is configured separately from the connecting member 35b is described, but a mode in which the knob 37 and the connecting member 35b are configured integrally is also possible.

The safety device 50 discharges the steam inside the pressure cooker when the internal pressure is equal to or higher than a second atmospheric pressure P2 (for example, 2.4 atmospheric pressure) that is greater than the first atmospheric pressure P1.
The safety device 50 functions when the pressure regulating device 30 does not operate normally and the internal pressure increases.
The safety device 50 has a valve 51 and a discharge portion (cover portion including a discharge port) 53 and is detachably attached to the lid body 10 .

バルブ５１の上端はねじ切りされていて、蓋本体１０に設けられた孔（バルブ孔１２ｃ）に螺着される。

圧力鍋の内圧が第２気圧Ｐ２未満の場合は、弁体が閉じるため、ここから圧力鍋の内部の蒸気は排出されない。 The upper end of the valve 51 is threaded and screwed into a hole (valve hole 12c) provided in the lid body 10 .
The discharge portion 53 is screwed to the upper end of the valve 51 , and the valve 51 and the discharge portion 53 sandwich the lid body 10 .
When the internal pressure of the pressure cooker is equal to or higher than the second atmospheric pressure P2, the pressure inside the pressure cooker opens a valve body (not shown) provided in the valve 51, and the steam inside the pressure cooker is discharged through the valve body. It is discharged from the discharge port provided in the portion 53 .
When the internal pressure of the pressure cooker is less than the second atmospheric pressure P2, the valve body closes, so the steam inside the pressure cooker is not discharged from here.

安全装置５０は１つだけ設けられる形態であってもよいが、２つ以上設けられる形態であってもよい。
第１実施形態では、２つの安全装置５０が設けられ、一方は第２気圧Ｐ２以上の時に、圧力鍋の内部の蒸気を排出させ、他方は第２気圧Ｐ２よりも大きい第３気圧Ｐ３（例えば、２．６気圧）以上の時に、圧力鍋の内部の蒸気を排出させる例を示す。 Only one safety device 50 may be provided, or two or more safety devices 50 may be provided.
In the first embodiment, two safety devices 50 are provided, one for discharging the steam inside the pressure cooker when the pressure is equal to or higher than the second pressure P2, and the other for discharging the steam inside the pressure cooker at a third pressure P3 (for example, , 2.6 atm), an example of discharging the steam inside the pressure cooker is shown.

（蒸気受け部７０）
蒸気受け部７０は、調圧装置３０から排出された蒸気、及び安全装置５０から排出された蒸気が拡散するのを防止するために使用される。
蒸気受け部７０は、蓋本体１０の上面であって、錘本体３５ａの側部の少なくとも一部を囲む位置に配置される。
蒸気受け部７０は、フェノール樹脂などの耐熱性樹脂若しくは金属で構成され、蓋本体１０と別体で構成される。 (Steam receiver 70)
The steam receiver 70 is used to prevent the steam discharged from the pressure regulator 30 and the steam discharged from the safety device 50 from diffusing.
The steam receiving portion 70 is arranged on the upper surface of the lid body 10 at a position surrounding at least part of the side portion of the weight body 35a.
The steam receiver 70 is made of heat-resistant resin such as phenolic resin or metal, and is separate from the lid body 10 .

蒸気受け部７０は、下面が開口し、外側側面部７１、内側側面部７３、上面部７５、リブ７６、突出部７９を有する。 The steam receiving portion 70 has an open lower surface and has an outer side surface portion 71 , an inner side surface portion 73 , an upper surface portion 75 , ribs 76 and a projecting portion 79 .

（外側側面部７１、内側側面部７３、上面部７５）
外側側面部７１は、下面が上面よりも大きい中空の略円錐台形状を有する。
内側側面部７３は、外側側面部７１の内側に設けられ、略円筒形状を有する。
内側側面部７３の上下方向の寸法は、外側側面部７１よりも短い。
上面部７５は、略ドーナツ形状を有し、外側の周縁部の下側に外側側面部７１の上端が接続され、内側の周縁部の下側に内側側面部７３の上端が接続される。 (outer side surface portion 71, inner side surface portion 73, upper surface portion 75)
The outer side surface portion 71 has a hollow truncated cone shape with a lower surface larger than an upper surface.
The inner side surface portion 73 is provided inside the outer side surface portion 71 and has a substantially cylindrical shape.
The vertical dimension of the inner side surface portion 73 is shorter than that of the outer side surface portion 71 .
The upper surface portion 75 has a substantially donut shape, and the upper end of the outer side surface portion 71 is connected to the lower side of the outer peripheral edge portion, and the upper end of the inner side surface portion 73 is connected to the lower side of the inner peripheral edge portion.

従って、蒸気受け部７０は、錘３５の上部を空けた状態で、錘３５の側部（錘本体３５ａの側部）の少なくとも一部を囲む。
すなわち、圧力鍋蓋１、及び圧力鍋蓋１と鍋本体９０を含む圧力鍋は、錘３５の上部の少なくとも一部が露出した状態で使用される。 Therefore, the steam receiver 70 surrounds at least a portion of the side portion of the weight 35 (the side portion of the weight body 35a) while leaving the upper portion of the weight 35 open.
That is, the pressure cooker lid 1 and the pressure cooker including the pressure cooker lid 1 and the pot main body 90 are used with at least a portion of the upper portion of the weight 35 exposed.

（リブ７６）
リブ７６は、外側側面部７１の内周面と内側側面部７３の外周面と接続し、上面部７５の下面に設けられる。
また、後述する突出部７９と内側側面部７３の外周面と接続する箇所にもリブ７６が設けられる。 (Rib 76)
The rib 76 connects the inner peripheral surface of the outer side surface portion 71 and the outer peripheral surface of the inner side surface portion 73 and is provided on the lower surface of the upper surface portion 75 .
Further, a rib 76 is also provided at a location where a projecting portion 79 (to be described later) is connected to the outer peripheral surface of the inner side surface portion 73 .

（カバー部７７、突出部７９）
上面部７５の下側には、外側側面部７１と内側側面部７３と上面部７５とリブ７６で囲まれた領域が複数（第１実施形態では４つ）形成される。
リブ７６などで囲まれた領域の幾つかには、安全装置５０の蓋本体１０から上方に露出した領域を上方から覆うカバー部７７が形成される。
リブ７６などで囲まれた領域のうち、カバー部７７が形成される領域とは別の領域には、上面部７５の下面から延び、外側側面部７１の下端よりも下方に突出し、蓋本体１０の凹部１２ａと接触する突出部７９が設けられる。
ただし、突出部７９は、外側側面部７１から下方に突出する形態であってもよいし、内側側面部７３から下方に突出する形態であってもよい。 (Cover portion 77, projecting portion 79)
A plurality of regions (four in the first embodiment) surrounded by the outer side surface portion 71 , the inner side surface portion 73 , the upper surface portion 75 , and the ribs 76 are formed below the upper surface portion 75 .
Some of the regions surrounded by the ribs 76 and the like are formed with cover portions 77 that cover the regions of the safety device 50 exposed upward from the lid body 10 from above.
Among the regions surrounded by the ribs 76 and the like, a region different from the region in which the cover portion 77 is formed extends from the lower surface of the upper surface portion 75 and protrudes below the lower end of the outer side surface portion 71, and the lid body 10 A protrusion 79 is provided for contacting the recess 12a.
However, the protruding portion 79 may protrude downward from the outer side surface portion 71 or may protrude downward from the inner side surface portion 73 .

外側側面部７１の下端よりも下方に突出する突出部７９が蓋本体１０の凹部１２ａに取り付けられることにより、外側側面部７１の下端（の少なくとも一部）と、内側側面部（の少なくとも一部）が、蓋本体１０と接しない状態で、蒸気受け部７０は、蓋本体１０の上部に取り付けられる。 The projecting portion 79 projecting downward from the lower end of the outer side surface portion 71 is attached to the recess 12a of the lid body 10, so that (at least a portion of) the lower end of the outer side surface portion 71 and (at least a portion of) the inner side surface portion ) is not in contact with the lid body 10 , the steam receiver 70 is attached to the upper portion of the lid body 10 .

リブ７６などで囲まれた領域のうちカバー部７７が形成されるものと、突出部７９が設けられるものとは、下方からみて円周方向に交互に配置される。
第１実施形態では、リブ７６などで囲まれた領域として、第１領域７０ａ、第２領域７０ｂ、第３領域７０ｃ、第４領域７０ｄが設けられ、第１領域７０ａと第３領域７０ｃにカバー部７７が形成され、第２領域７０ｂと第４領域７０ｄに突出部７９が設けられる例を示す。 Of the areas surrounded by the ribs 76 and the like, the areas where the cover portions 77 are formed and the areas where the projecting portions 79 are provided are alternately arranged in the circumferential direction when viewed from below.
In the first embodiment, a first region 70a, a second region 70b, a third region 70c, and a fourth region 70d are provided as regions surrounded by the ribs 76 and the like, and the first region 70a and the third region 70c are covered. An example is shown in which a portion 77 is formed and protrusions 79 are provided in the second region 70b and the fourth region 70d.

蒸気受け部７０は、蓋本体１０の上面であって土台部１２の上に取り付けられる。
内側側面部７３の内側に、ノズル３３と錘本体３５ａが配置される。
蒸気受け部７０の土台部１２への取り付けは、上方から突出部７９に設けられたネジ孔７９ａを貫通するネジ８０をネジ受け１２ｄと螺合させることにより行われる。 The steam receiving part 70 is attached on the top surface of the lid body 10 and on the base part 12 .
The nozzle 33 and the weight body 35a are arranged inside the inner side surface portion 73 .
The steam receiving portion 70 is attached to the base portion 12 by screwing a screw 80 passing through a screw hole 79a provided in the projecting portion 79 from above into the screw receiving portion 12d.

外側側面部７１の下端、及び内側側面部７３の下端は、土台部１２と接しない。
ノズル３３と錘３５の間から排出された蒸気が、内側側面部７３と蓋本体１０（土台部１２）の間、蒸気受け部７０の下部を通って、外側側面部７１と蓋本体１０（土台部１２）の間から外部に排出されるように、蒸気受け部７０と蓋本体１０の間には、蒸気誘導領域１００が形成される。 The lower end of the outer side surface portion 71 and the lower end of the inner side surface portion 73 do not contact the base portion 12 .
Steam discharged from between the nozzle 33 and the weight 35 passes between the inner side surface portion 73 and the lid body 10 (base portion 12), passes through the lower portion of the steam receiving portion 70, and flows between the outer side surface portion 71 and the lid body 10 (base portion 12). A steam guiding area 100 is formed between the steam receiving part 70 and the lid body 10 so that the steam is discharged to the outside from between the parts 12).

つまみ３７を動かした時に錘本体３５ａを動かすことができるように、内側側面部７３の内径は、錘本体３５ａの外径よりも大きい。
すなわち、錘本体３５ａと蒸気受け部７０との間に隙間が形成される。 The inner diameter of the inner side surface portion 73 is larger than the outer diameter of the weight body 35a so that the weight body 35a can be moved when the knob 37 is moved.
That is, a gap is formed between the weight main body 35a and the steam receiving portion 70. As shown in FIG.

圧力鍋の内圧が第１気圧Ｐ１以上に高くなると、ノズルフィルター３１を介してノズル３３に流れる蒸気の圧力で錘３５（錘本体３５ａと接続部材３５ｂ）が押し上げられ、当該蒸気の一部が、ノズル３３と錘３５の間から排出される（図７の太い破線矢印参照）。
蒸気が排出されることにより、内圧は下がり、一旦ノズル３３の先端は錘３５によって閉じられるが、再び内圧が第１気圧Ｐ１以上に高くなると、錘３５が押し上げられて蒸気の排出が行われる。
従って、加熱中は、ノズル３３と錘３５の間が開口した状態と閉口した状態が繰り返される。
また、圧力鍋の内圧が第１気圧Ｐ１未満の場合でも、第１切り欠き３５ｂ３によって、ノズル３３と接続部材３５ｂの間に形成された蒸気排出領域を介して、圧力鍋の内部の蒸気が排出される。 When the internal pressure of the pressure cooker becomes higher than the first atmospheric pressure P1, the pressure of the steam flowing through the nozzle filter 31 to the nozzle 33 pushes up the weight 35 (the weight body 35a and the connection member 35b), and part of the steam is It is discharged from between the nozzle 33 and the weight 35 (see the thick dashed arrow in FIG. 7).
As the steam is discharged, the internal pressure decreases, and the tip of the nozzle 33 is temporarily closed by the weight 35. When the internal pressure again rises above the first atmospheric pressure P1, the weight 35 is pushed up to discharge the steam.
Therefore, during heating, the state in which the nozzle 33 and the weight 35 are open and the state in which they are closed are repeated.
Further, even when the internal pressure of the pressure cooker is less than the first atmospheric pressure P1, the steam inside the pressure cooker is discharged through the steam discharge region formed between the nozzle 33 and the connection member 35b by the first notch 35b3. be done.

ノズル３３と錘３５の間から排出された蒸気は、蓋本体１０の土台部１２と蒸気受け部７０の間で冷却されて一部が液化し、凹部１２ａに貯まる。空気及び液化しなかった蒸気は、外側側面部７１と土台部１２の間から排出される（図７などの細い破線矢印参照）。 The steam discharged from between the nozzle 33 and the weight 35 is cooled between the base portion 12 of the lid body 10 and the steam receiving portion 70, partially liquefied, and accumulated in the concave portion 12a. Air and unliquefied vapor are discharged from between the outer side surface portion 71 and the base portion 12 (see thin dashed arrows in FIG. 7, etc.).

（効果）
圧力鍋の内圧に関わらず、また、つまみ３７を操作することなく、蒸気排出領域を介して、圧力鍋の内部の蒸気を排出させることが出来る。
このため、蒸気排出領域を設けない形態に比べて、加熱を止めた後、圧力鍋の内圧を下げて、圧力鍋蓋１を鍋本体９０から取り外すことが出来るようになるまでの時間を、短くすることが可能になる。
圧力鍋蓋１を鍋本体９０から取り外すことが出来るようになるまでの時間を短くすることで、煮込み過ぎを防ぎ、所望の時間で調理を行うことが容易になる。 (effect)
Regardless of the internal pressure of the pressure cooker, the steam inside the pressure cooker can be discharged through the steam discharge area without operating the knob 37.
For this reason, compared to a form in which no steam discharge area is provided, the time until the pressure cooker lid 1 can be removed from the pot body 90 by lowering the internal pressure of the pressure cooker after stopping heating is shortened. it becomes possible to
By shortening the time until the pressure cooker lid 1 can be removed from the pot body 90, overcooking can be prevented and cooking can be easily performed within a desired time.

また、第１切り欠き３５ｂ３をねじ部３５ｂ１とニードル部３５ｂ２に設けた接続部材３５ｂを用意するだけで、蒸気排出領域を形成出来る。このため、圧力鍋蓋１の接続部材３５ｂ以外の部材を流用して、第１実施形態の圧力鍋蓋を用意することが出来る。 Further, the steam discharge area can be formed only by preparing the connection member 35b having the first notch 35b3 provided on the threaded portion 35b1 and the needle portion 35b2. Therefore, the pressure cooker lid of the first embodiment can be prepared by using the members other than the connection member 35b of the pressure cooker lid 1.

また、ニードル部３５ｂ２だけでなく、ねじ部３５ｂ１にまで第１切り欠き３５ｂ３が設けられる。このため、ニードル部３５ｂ２にだけ第１切り欠き３５ｂ３が設けられる形態に比べて、略円柱形状で構成されたねじ部３５ｂ１の外形寸法を確認しながら、容易に所望の切り欠き量を有する第１切り欠き３５ｂ３を形成することが出来る。
ただし、ねじ部３５ｂ１に第１切り欠き３５ｂ３を設けずに、ニードル部３５ｂ２にだけ第１切り欠き３５ｂ３を設ける形態であってもよい。 A first notch 35b3 is provided not only to the needle portion 35b2 but also to the threaded portion 35b1. For this reason, compared to the configuration in which the first notch 35b3 is provided only in the needle portion 35b2, the first notch having the desired notch amount can be easily obtained while checking the external dimensions of the substantially cylindrical thread portion 35b1. A notch 35b3 can be formed.
However, the first notch 35b3 may be provided only in the needle portion 35b2 without providing the first notch 35b3 in the threaded portion 35b1.

（切り欠き量が異なる複数種類の接続部材３５ｂ）
また、第１切り欠き３５ｂ３の切り欠き量が異なる接続部材３５ｂを複数設けてもよい。
この場合には、用途に応じて、複数の接続部材３５ｂのいずれかを選択して使用することが可能になる。
例えば、切り欠き量が少ない第１切り欠き３５ｂ３を有する第１の接続部材３５ｂが選択された場合には、蒸気排出領域を介して排出される蒸気が少なくなる。このため、短い加熱時間で調理を行いやすい。
また、例えば、切り欠き量が多い第１切り欠き３５ｂ３を有する第２の接続部材３５ｂが選択された場合には、蒸気排出領域を介して排出される蒸気が多くなる。このため、第１の接続部材３５ｂを用いる場合に比べて、加熱を止めた後、早期に圧力鍋の内圧を下げて、早期に圧力鍋蓋１を鍋本体９０から取り外すことが出来る。 (Plural types of connection members 35b with different notch amounts)
Further, a plurality of connection members 35b having different cutout amounts of the first cutouts 35b3 may be provided.
In this case, it becomes possible to select and use any one of the plurality of connection members 35b according to the application.
For example, when the first connection member 35b having the first cutout 35b3 with a small cutout amount is selected, less steam is discharged through the steam discharge region. Therefore, it is easy to cook in a short heating time.
Further, for example, when the second connection member 35b having the first cutout 35b3 with a large cutout amount is selected, the amount of steam discharged through the steam discharge region increases. Therefore, compared to the case of using the first connection member 35b, the pressure cooker lid 1 can be removed from the pot body 90 early after the heating is stopped by lowering the internal pressure of the pressure cooker earlier.

また、圧力鍋の内部から排出された蒸気の一部を液化して凹部１２ａに貯めておくことが出来るので、外部に排出される蒸気の量を少なく出来る。このため、高温の蒸気が使用者に触れる可能性を低く出来る。
また、液化した水が蓋本体１０の上面に流れるのを抑制することも出来る。 Further, since part of the steam discharged from the inside of the pressure cooker can be liquefied and stored in the recess 12a, the amount of steam discharged to the outside can be reduced. Therefore, it is possible to reduce the possibility that the high-temperature steam comes into contact with the user.
Also, it is possible to suppress the liquefied water from flowing to the upper surface of the lid body 10 .

また、蒸気受け部７０は、錘３５の錘本体３５ａの上部を覆わないので、錘本体３５ａが外部から見える状態が維持され、錘本体３５ａの上部が蒸気受け部７０などによって覆われる形態に比べて、錘本体３５ａを含む錘３５の状態が視認しやすくなる。 In addition, since the steam receiver 70 does not cover the upper portion of the weight body 35a of the weight 35, the weight body 35a remains visible from the outside. Therefore, the state of the weight 35 including the weight body 35a can be easily visually recognized.

液化しなかった蒸気は、外側側面部７１と蓋本体１０の土台部１２の間から排出されるため、錘本体３５ａと蒸気受け部７０の間からは殆ど排出されない。
このため、つまみ３７を介して錘３５を操作する使用者に蒸気が当たりにくく出来る。 Since the steam that has not been liquefied is discharged from between the outer side surface portion 71 and the base portion 12 of the lid body 10 , it is hardly discharged from between the weight body 35 a and the steam receiving portion 70 .
For this reason, the user who operates the weight 35 via the knob 37 is less likely to be exposed to the steam.

また、蒸気受け部７０と土台部１２の間の蒸気誘導領域１００を通過する際に、蒸気の発生音の音質を変えることが出来る。
蒸気排出領域の形状、及び蒸気受け部７０の外側側面部７１と蓋本体１０の土台部１２の隙間の形状などを変えることにより、蒸気の発生音の音質を調整することも出来る。
このため、蒸気受け部７０を設けない形態に比べて、音量を下げたり、音質を変えたりした状態で、蒸気を排出することが可能になる。 Further, when passing through the steam guiding region 100 between the steam receiving portion 70 and the base portion 12, the sound quality of the generated steam can be changed.
By changing the shape of the steam discharge region and the shape of the gap between the outer side surface portion 71 of the steam receiving portion 70 and the base portion 12 of the lid body 10, the sound quality of the steam generation sound can be adjusted.
Therefore, steam can be discharged while the volume is lowered or the sound quality is changed, compared to a form in which the steam receiver 70 is not provided.

また、蒸気受け部７０に設けられたカバー部７７が安全装置５０の上部を覆うため、調圧装置３０が正常に動作せずに、安全装置５０を介して圧力鍋の内部の蒸気が排出される場合に、圧力鍋の内圧によって安全装置５０の上部の螺着が外れても、当該上部の部材（排出部５３）が飛び散るのを防止する。 In addition, since the cover part 77 provided in the steam receiving part 70 covers the upper part of the safety device 50, the pressure regulator 30 does not operate normally, and the steam inside the pressure cooker is discharged through the safety device 50. In this case, even if the upper part of the safety device 50 is unscrewed due to the internal pressure of the pressure cooker, the upper member (discharge part 53) is prevented from scattering.

また、調圧装置３０と、安全装置５０と、蒸気受け部７０が着脱可能な状態で蓋本体１０に取り付けられるため、蒸気受け部７０に相当する部分などが蓋本体１０と一体的に構成される形態に比べて、掃除などのメンテナンスが容易に行える。 In addition, since the pressure regulator 30, the safety device 50, and the steam receiver 70 are detachably attached to the lid body 10, the portion corresponding to the steam receiver 70 and the like are configured integrally with the lid body 10. Maintenance such as cleaning can be easily performed compared to the form of

（第２実施形態、ノズル３３の第２切り欠き３３ａ）
また、第１実施形態では、蒸気排出領域を形成するために接続部材３５ｂに第１切り欠き３５ｂ３が設けられる例を説明した（図５～図１１参照）。
ただし、蒸気排出領域を形成するためにノズル３３に第２切り欠き３３ａが設けられる形態であってもよい（第２実施形態、図１２～図１４参照）。
この場合、ノズル３３の先端で接続部材３５ｂのニードル部３５ｂ２が接する領域に第２切り欠き３３ａが設けられる。
第２切り欠き３３ａにより、ノズル３３と接続部材３５ｂの間には蒸気排出領域が形成される。
第２切り欠き３３ａにより、ノズル３３と接続部材３５ｂの間に形成される蒸気排出領域の開口部ａ２（図１４参照）の開口面積が、ノズル３３における接続部材３５ｂと対向する領域の開口部ｂ１（図１３参照）の開口面積よりも小さくなるように、第２切り欠き３３ａが形成される。
当該蒸気排出領域を介して、圧力鍋の内部の蒸気が排出される。 (Second embodiment, second notch 33a of nozzle 33)
Further, in the first embodiment, an example in which the connecting member 35b is provided with the first notch 35b3 in order to form the steam discharge area has been described (see FIGS. 5 to 11).
However, the nozzle 33 may be provided with a second notch 33a to form the steam discharge area (second embodiment, see FIGS. 12 to 14).
In this case, a second notch 33a is provided at the tip of the nozzle 33 in a region where the needle portion 35b2 of the connecting member 35b contacts.
A steam discharge area is formed between the nozzle 33 and the connecting member 35b by the second notch 33a.
The opening area of the opening a2 (see FIG. 14) of the steam discharge region formed between the nozzle 33 and the connection member 35b is reduced by the second notch 33a to the opening b1 of the region of the nozzle 33 facing the connection member 35b. The second notch 33a is formed so as to be smaller than the opening area of (see FIG. 13).
Steam inside the pressure cooker is discharged through the steam discharge area.

（第２切り欠き３３ａの形成方法）
第２切り欠き３３ａを有するノズル３３は、第２切り欠き３３ａを有しないノズル３３から削り出しなどにより形成される。
ただし、第２切り欠き３３ａを有するノズル３３は、削り出し以外の他の方法で形成されてもよい。
例えば、第２切り欠き３３ａを含むノズル３３を金型で形成する形態が考えられる。 (Method of Forming Second Notch 33a)
The nozzle 33 having the second notch 33a is formed by cutting out from the nozzle 33 having no second notch 33a.
However, the nozzle 33 having the second notch 33a may be formed by a method other than cutting.
For example, a form in which the nozzle 33 including the second notch 33a is formed by a mold is conceivable.

（第１切り欠き３５ｂ３と第２切り欠き３３ａ）
接続部材３５ｂの第１切り欠き３５ｂ３と、ノズル３３の第２切り欠き３３ａは、いずれか一方だけが設けられてもよいし、両方が設けられてもよい。
ただし、第１切り欠き３５ｂ３と第２切り欠き３３ａの両方が設けられる場合には、第１切り欠き３５ｂ３と第２切り欠き３３ａにより、ノズル３３と接続部材３５ｂの間に形成される蒸気排出領域の開口部の開口面積が、ノズル３３における接続部材３５ｂと対向する領域の開口部の開口面積よりも小さくなるように、第１切り欠き３５ｂ３と第２切り欠き３３ａが形成される。 (First cutout 35b3 and second cutout 33a)
Either one of the first notch 35b3 of the connecting member 35b and the second notch 33a of the nozzle 33 may be provided, or both may be provided.
However, when both the first notch 35b3 and the second notch 33a are provided, the steam discharge region formed between the nozzle 33 and the connecting member 35b by the first notch 35b3 and the second notch 33a The first notch 35b3 and the second notch 33a are formed such that the opening area of the opening of the nozzle 33 is smaller than the opening area of the opening of the region of the nozzle 33 facing the connection member 35b.

（第３実施形態、蒸気排出領域を形成する他の形態）
第１実施形態と第２実施形態では、調圧装置３０（ノズル３３若しくは接続部材３５ｂの少なくとも一方）に蒸気排出領域を形成するための切り欠き（第１切り欠き３５ｂ３、第２切り欠き３３ａ）が設けられる例を説明した。
しかしながら、圧力鍋蓋１における蓋本体１０など、調圧装置３０以外の領域に、蒸気排出領域を形成するための貫通孔１５が設けられる形態であってもよい（第３実施形態、図１５参照）。
この場合、蒸気排出領域を形成するための貫通孔１５の開口面積が、ノズル３３における接続部材３５ｂと対向する領域の開口部ｂ１の開口面積よりも小さくなるように、当該貫通孔１５が形成される。
また、貫通孔１５は、ノズル３３に設けられてもよい。 (Third embodiment, another form of forming a steam discharge area)
In the first and second embodiments, cutouts (first cutout 35b3, second cutout 33a) for forming a steam discharge region in the pressure regulator 30 (at least one of the nozzle 33 and the connection member 35b) has been described.
However, there may be a configuration in which a through hole 15 for forming a steam discharge region is provided in a region other than the pressure regulator 30, such as the lid body 10 of the pressure cooker lid 1 (third embodiment, see FIG. 15). ).
In this case, the through hole 15 for forming the steam discharge region is formed such that the opening area of the through hole 15 is smaller than the opening area of the opening b1 of the region facing the connection member 35b in the nozzle 33. be.
Also, the through hole 15 may be provided in the nozzle 33 .
