Cirulating type water flow pool

Abstract

A circulating type water flow pool having a tank portion and a circulating passage formed in a lower portion thereof. The circulating passage has a riser portion at one end which extends to an upper portion of the tank portion. A delivery port is formed in the end of the circulating passage in communication with the tank portion. At its other end, the circulating passage is formed with an intake port in communication with the tank portion, and a water flow control member is mounted on the delivery port at the riser portion of the circulating passage. A screw blade of a delivery unit is actuated by a driving motor, and it is disposed facing the delivery port. Water in the circulating passage is sucked out by the screw action of the screw blade, creating a jet flow, which is delivered toward the delivery port. The jet flow is straightened by a water flow control member mounted on the delivery port, thereby creating a powerful water flow. The water jet flows into the tank portion and is introduced into the intake port formed on the other end of the tank portion. Water introduced into the intake portion moves within the circulating passage and it is again guided to the delivery port. This is repeated to forcibly and continuously circulate the water.
