A foot water-spouting device includes a foot-front water spouting section for spouting water toward the front side of a user's foot and a water-spouting section direction moving mechanism for reciprocating the destination of water spouting of the foot-front water spouting section along a longitudinal direction of the foot. A plurality of spouts may be arranged side-by-side in the foot instep width direction for each of the right and left feet. The pressure of water spouting at a water arrival point may be changed based on or the water spouting amount may be changed based on movement of the water arrival point.

Foot water jetting device

A cleaning water jetting deviceformed so as to rotate a nozzle by a fluid pressure and capable of reducing the size of the drive part of a pump for feeding fluid to a chamber and an operation cost, comprising an upper side through-holeA recessedly formed in edge shape provided in the ceiling of the chamberand a bottomed concave partformed in round hole shape provided in the bottom surface thereof, wherein the nozzleis installed by inserting a reduced diameter parton a nozzle tip side at the nozzle tip side into the upper side through-holeA and the bottom portioninto the concave partand kept in such a state in the upper side through-holeA as to face a cleaning fluid jetting porttoward the outside of the through-hole, to be rotated, and to allow the position thereof to be changed in a nozzle axis O direction, and can be revolved around the center axis thereof in the tilted attitude relative to the center axis P of the upper side through-holeA.

Fluid jetting device

A novel water jetting device achieves a water jet of a wide range and an economization of water without using an electric drive device. A water jetting body is so vortex chamber with its water jetting spout confronting the outside of the force receiving member that a force receiving member can oscillate in a position inclined in the vortex chamber . A vortex flow thus established in the vortex chamber is caused to make a flow velocity difference around the force receiving member , and a force generated on the basis of the flow velocity difference is exerted upon the force receiving member to oscillate the water jetting body in the inclined position in the vortex chamber thereby to jet the cleaning water in the vortex chamber from the water jetting spout

Water discharging device

A multi-layer disk fan with blades operates quietly. The multi-layer disk fan with blades is formed by laminating a multiplicity of annular disks in a measured spaced relation, the arrangement having such a feature that a multiplicity of blades are interposed between the annular disks and the ends of the respective blades. The blades are further positioned a circumferentially measured spaced apart distance inward of the outer peripheral edges of the annular disks. Turbulent air flow caused by peeling-off at the tips of the blades through the effect of laminar flow by the disks is effectively prevented. Likewise, distortion in outlet speed at the outer peripheral edges of the annular disks is controlled, reducing noises from turbulent flow and interference and resulting in quiet operation.

Multi-stacked circular plate fan provided with blades

Rotatable circular plates are stacked apart to form thin air layers therebetween. Rotation of the circular plates moves air over an air treatment material: catalyst or adsorbent. In one embodiment, the air treatment material is affixed to the surface of the circular plates. In another embodiment, the circular plates are formed from the air treatment material. The increased velocity of air relative to the circular plates causes separation of laminar flow, promotes boundary-layer turbulence near the plate surfaces, and promotes propagating stall in the air layers. These phenomena enhance the contact between the flowing air and the air treatment material.
