Swimming Pool Cleaner

摘要

Disclosed herein are a steering system for a suction cleaning device, a locomotion system for a pool cleaner, and a turbine for use in an automatic cleaner. The steering system includes a fluid driven turbine that rotates a cam gear that is interconnected with a cam wheel for directing a drive pinion. The drive pinion is positionable in a plurality of positions to drive a nose cone that steers the suction cleaning device. The locomotion system includes first and second A-frame arms that respectively engage first and second bearings about first and second eccentrics of a turbine. Rotation of the turbine causes the first and second A-frame arms to rotate back and forth driving associated walking pod assemblies. The turbine includes a turbine rotor and a plurality of vanes connected to the turbine rotor. The plurality of vanes including lateral edges having lateral open regions to facilitate debris-removing efficiency.

1. In an automatic pool cleaner of the type motivated by flow of water therethrough to move along a pool surface to be cleaned, the flow of water being established by pumping action of a remote pump communicating with the pool-cleaner body through a hose connected thereto, the pool cleaner including a steering system connected to the hose to direct movement of the pool cleaner with respect to the hose, the improvement comprising:
a steering drive mechanism secured with respect to the cleaner body and including a main rotatable member; a steering drive train from the main rotatable member to a steering mechanism which is secured with respect to the hose and steers the cleaner body in a plurality of directions with respect to the hose, the steering mechanism including first and second gear tracks for steering movement of the cleaner body with respect to the hose; and a cam drive train from the main rotatable member to a cam mechanism which includes a cam wheel rotatably secured with respect to the cleaner body and operatively connected to the steering mechanism, the cam wheel having outer-profile regions of greater and lesser radii each corresponding to one of the directions of the steering mechanism.
