特許文献１において、液体の煮沸時に関すればその撹拌は自然対流に依存する。特許文献２において、渦巻き水流を発生させる板は複数の孔によるものであり、自由落下する流れの収束した排水に有効であっても、煮沸時の上昇対流を渦巻き水流に変流させる効果は低いと思われる。加熱調理容器の内側にはめ込む羽根を施した円筒状のものは、渦巻き水流に効果的であるが、容器内周の上昇対流を変流させるため低い水位では効果が小さく、バーナー式加熱器特有の対流に限定され、調理後の円筒の洗浄はその複雑な形状のため手間を要する。   In Patent Document 1, if the liquid is boiled, the stirring depends on natural convection. In Patent Document 2, the plate that generates the swirling water flow is due to a plurality of holes, and even if effective for draining the converged free-falling flow, the effect of transforming the rising convection into a swirling water flow is low. I think that the. The cylindrical shape with blades fitted inside the cooking container is effective for swirling water flow, but it is not effective at low water levels because it transforms the rising convection in the inner periphery of the cooking vessel. It is limited to convection, and the cleaning of the cylinder after cooking requires labor due to its complicated shape.

上記課題を解決するために本発明は、容器底全面の上昇対流を渦巻き水流に変流させるべく、円板をその外径が容器垂直部下端内径よりわずかに小さなものとしたうえで、円板の中央部のみを残し放射状か渦状になるよう半径方向に切り分けて複数枚の羽根を形成し、容器底に沈めるものである。羽根の切り分け部の片側に半径方向外向きの小さな仰角をつけ、もう一方側は中央部と同レベルの水平を保つようにし、羽根の半径方向片側だけを小さくねじり上げたような塑性変形をさせておく。複数枚に切り分けられた各々の羽根の外側円弧を、その一角の円板外径は維持したうえでもう一角に向けて平面的なテーパー状に切り欠いてもよく、羽根はフラットのままあるいは円板外径を維持した長めの側だけを小さくねじり上げたような塑性変形をさせておく。また、円板の中央部と外周枠を残し放射状か渦状になるよう半径方向から外側円弧にかけてのＬ字形の切り込みによる羽根を複数枚配置し、各羽根に間隔をあけて中央部と外周枠を繋げる形状としてもよく、羽根はフラットのままあるいは半径方向側を小さく折り上げる。   In order to solve the above-mentioned problem, the present invention aims to transform the upward convection on the entire surface of the container into a swirling water flow with the outer diameter of the disk slightly smaller than the inner diameter of the lower end of the vertical portion of the container. A plurality of blades are formed by cutting in the radial direction so that only the central part of the container is left in a radial or spiral shape, and is submerged in the bottom of the container. A small elevation angle outward in the radial direction is given to one side of the blade cutting part, and the other side is kept at the same level as the central part, and only one side in the radial direction of the blade is plastically deformed. Keep it. The outer circular arc of each blade cut into a plurality of sheets may be cut out into a flat taper toward the other corner while maintaining the outer diameter of one disk, and the blade remains flat or circular. Only the longer side maintaining the outer diameter of the plate is plastically deformed as if it was slightly twisted up. In addition, a plurality of blades with L-shaped cuts from the radial direction to the outer arc are arranged so that the central portion and the outer peripheral frame of the disk are left in a radial or spiral shape, and the central portion and the outer peripheral frame are spaced apart from each other. The blades may be connected to each other, and the blades are kept flat or folded up in the radial direction.

本発明において、容器底に沈められた円板は容器内径に対しあそび寸法がわずかであるので、その配置が安定する。円板は容器底ほぼ全面の上昇対流を狭い空間で受けることにより水の膨張圧力を増大させ、小さな傾斜角の羽根の内側に沿って小さな隙間からジェット水流のように噴出し容器内周がガイド役ともなり水平方向に渦巻き水流を発生させる。容器底ほぼ全面の上昇対流を変流させるため低い水位でも効果が出易く、バーナー式加熱器だけでなく、電磁式加熱器にも対応し易い。使用後の円板の洗浄は、円筒に比べ表面積が小さく、平面的な形状と羽根の円形配置により、手で洗うときは渦巻き水流の方向に押し回すようにすれば比較的手間が少ない。予め小さな傾斜角の羽根を塑性変形させているものではなく、切り分けたままのフラットな円板で羽根外側円弧をテーパー状に切り欠いている場合、一般的なプレス絞り加工容器にみられる容器底丸み角の上部に円板外径を維持した方の羽根の一角各々が点接触保持されると、薄板の場合は自重や円板中央部上側に降りてくる下降対流水圧により円板中央部がへこんだ状態に弾性変形し、同時にテーパー状の切り欠き部も下がり小さな傾斜角の羽根を形成することになる。同じ場合に、円板外径が容器底丸み角にかからず即ち容器底に全く水平に沈んだ状態でも、煮沸時の上昇対流は羽根の円板外径を維持した長めの側により強い上曲げモーメントとして作用し、暫定的にわずかな傾斜角の羽根を形成する。中央部と外周枠を繋げる形状のものは、円板の取扱いが容易となり、羽根がフラットの場合は煮沸時の上昇対流により暫定的にわずかな傾斜角の羽根を形成する。どの形状の円板においても、その外径が容器内径に近い方が容器内周の強い上昇対流を受けてより強い渦巻き水流を発生させるが、円板外径が容器内径より少々小さくとも渦巻き水流は発生するので、多少サイズの違う容器にも使用でき、容器深さの制約が無いので、加熱調理容器以外に湯沸かし容器等にも使用できる。ただし、円板外径が容器内径よりかなり小さいときは、その配置が不安定になり水流が乱れたり円板自体が回転したりするので、厚めの板材で自重を増やしたり磁石や錘で安定配置に努める必要がある。   In the present invention, the disk sunk in the container bottom has a small play size with respect to the inner diameter of the container, so that the arrangement is stable. The disk receives the rising convection of almost the entire surface of the container in a narrow space, thereby increasing the expansion pressure of the water, and the inner periphery of the ejection container is guided like a jet water stream from a small gap along the inside of the blade with a small inclination angle. It also plays a role and generates a spiral water flow in the horizontal direction. Since the rising convection on the almost entire surface of the container is transformed, it is easy to achieve an effect even at a low water level, and it is easy to deal with not only a burner type heater but also an electromagnetic type heater. Washing the disc after use has a smaller surface area than a cylinder, and it is relatively troublesome if it is swung in the direction of the swirling water flow when washed by hand due to the planar shape and the circular arrangement of the blades. The bottom of the container found in a typical press-drawn container when the blade outer arc is notched in a tapered shape with a flat disk that has been cut in advance, instead of plastically deforming a blade with a small inclination angle in advance. If each corner of the blade that maintains the outer diameter of the disk is held in point contact at the upper part of the rounded corner, in the case of a thin sheet, the center part of the disk is moved by its own weight or by downward convection water pressure that descends above the center part of the disk. At the same time, it is elastically deformed into a dented state, and at the same time, the tapered notch is lowered to form a blade having a small inclination angle. In the same case, even when the outer diameter of the disc does not reach the round bottom corner of the container, i.e., when it sinks completely horizontally on the bottom of the container, the rising convection during boiling is stronger on the longer side that maintains the outer diameter of the blade disk. It acts as a bending moment, provisionally forming a blade with a slight inclination angle. The shape connecting the central portion and the outer peripheral frame facilitates the handling of the disc. When the blade is flat, the blade with a slight inclination angle is provisionally formed by ascending convection during boiling. Regardless of the shape of the disk, the outer diameter closer to the inner diameter of the container will generate stronger swirling water flow due to strong rising convection on the inner circumference of the container. Can be used in containers of slightly different sizes, and since there is no restriction on the depth of the container, it can also be used in water heater containers as well as cooking containers. However, when the outer diameter of the disc is much smaller than the inner diameter of the container, the arrangement becomes unstable, the water flow is disturbed, and the disc itself rotates, so the thicker plate material increases its own weight or stable placement with magnets and weights. It is necessary to strive for.
