  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.

  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.

  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.

  In order to carry out the present invention, a plurality of blades are formed by cutting in the radial direction so that only the central portion of the disk is left in a radial or spiral shape, and plastic deformation is performed such that only one side in the radial direction of the blade is slightly twisted up. Then, it is submerged in the bottom of a heating cooking vessel or a kettle, and the rising convection at the bottom of the vessel is transformed into a spiral water flow during boiling.

  Dividing in the radial direction so that only the central part of the disk is left in a radial or spiral shape, multiple blades are formed, and the outer circular arc of each blade is maintained at the outer diameter of the disk and directed to the other corner. The blades are cut into a flat taper shape, and the blades remain flat or are plastically deformed by slightly twisting only the longer side that maintains the outer diameter of the disc, and then submerged in the bottom of the cooking or watering vessel. When boiling, the rising convection at the bottom of the container is transformed into a spiral water flow.

  A shape in which a plurality of blades with L-shaped cuts from the radial direction to the outer arc are arranged to leave a central portion of the disc and the outer peripheral frame, and the central portion and the outer peripheral frame are connected with a space between each blade. The blades are flat or folded up in the radial direction and are submerged in the bottom of the heating cooking vessel or the kettle, and the rising convection at the bottom of the vessel is transformed into a spiral water flow during boiling.

  The embodiment will be described with reference to the drawings. FIG. 1 shows a plurality of blades that are radially divided so that only the central portion of the disk remains in a radial shape, and FIG. It is formed and plastically deformed such that only one side in the radial direction of the blade is slightly twisted up. Fig. 3 shows a radial shape leaving only the central portion of the disc, while Fig. 4 shows a plurality of blades cut in a radial direction leaving only the central portion of the disc and forming a spiral shape. While maintaining the outer diameter of one disk, it was cut out into a flat taper 1 toward the other, and the blades were flat or only the longer side that maintained the outer diameter of the disk was slightly twisted up. It causes plastic deformation. FIG. 5 shows a plurality of blades with L-shaped cuts from the radial direction to the outer arc so as to form a vortex, leaving the central portion of the disc and the outer peripheral frame 2 and leaving a central portion of the disc and the outer peripheral frame 2 in FIG. The blades are arranged so that each blade is spaced from each other so that the central portion and the outer peripheral frame 2 are connected to each other, and the blades are flat or folded up in the radial direction.

  FIG. 7 is a side view of the embodiment shown in FIG. 3, in which the blade is plastically deformed as if it is slightly twisted up. 8 and 9 show a state in use of the embodiment of FIG. 3, and the outer diameter of the disk is formed on the upper part of the container bottom rounding corner 3 by the taper 1-shaped notch of the outer arc of the blade even when the blade remains flat. Each corner of the blade is maintained in point contact, and elastically deforms into a state where the central part of the disk is dented due to its own weight or the downward convection water pressure descending to the upper part of the central part of the disk, and at the same time a notch with a taper 1 shape. The part also falls to form a blade with a small inclination angle.

  It is expected that the convenience of the swirling water flow generating plate during boiling will be enhanced by a simple shape.
