容器内の液体を撹拌する。(5) Operation In the present invention having the above-described structure, when a moving magnetic field is generated in the stator, the rotor starts to rotate, and the liquid between the upper surface of the rotor and the upper surface of the housing is subjected to centrifugal force as the rotor rotates. However, since the gap between the inner peripheral surface of the rotor and the outer peripheral surface of the housing is small, the outflow through the gap is small and the upper surface of the rotor is transparent. Liquid flows in from the holes, and thus the liquid pressure of the liquid is increased between the upper surface of the rotor and the upper surface of the housing. As a result, the rotor generates an upward lift and floats. The liquid balances with the stirring reaction force of the stirring blades on the upper surface of the rotor, and the fluid discharged from the gap between the circumferential surface of the rotor and the housing generates a fluid bearing action in the radial direction to smoothly rotate the rotor. Stir the liquid in the container.

る。(7) Effects of the Invention As described above, the present invention rotatably covers the outer surface of a casing made of a non-magnetic material surrounding a stator with a cup-shaped rotor having stirring blades, and forms a through hole on the upper surface of the rotor. In addition, since the gap between the inner peripheral surface of the rotor and the outer peripheral surface of the housing is made small, the liquid flows between the rotor and the housing while the liquid flows in and supplied from the through holes with the rotation of the rotor. The centrifugal force causes the liquid pressure to gradually rise and flow out. Thus, the rotor rotates smoothly while floating, and the stirring in the container is smoothly performed. The process is extremely easy, and it can be used irrespective of the sealed or non-sealed container.It has a simple structure, easy to handle, and can be made small. It has the effect that it can be reduced.
