  • the swimming pool cleaner 400 includes a drive member 406 which rotates about a drive member axle/shaft 414, a single motor 404 and a filter 408 at least partially within the housing 402.
  • swimming pool cleaner 400 can include a drive mechanism (e.g., similar to drive mechanism 310, etc.) driven by the motor 404 to regulate the direction of motion of at least one wheel (e.g., a wheel associated with a belt, rollers, and the like).
  • the single motor 404 provides power for both the drive member 406 and the wheel(s), thus reducing the cost and/or maintenance associated with the swimming pool cleaner 400.

Abstract

La présente invention concerne des mécanismes améliorés d'entraînement d'appareil de nettoyage de piscine et des procédés associés. Plus particulièrement, l'invention concerne un mécanisme amélioré d'entraînement d'appareil de nettoyage de piscine qui comprend un moteur qui alimente : (i) une ou plusieurs roues et (ii) un élément d'entraînement de l'appareil de nettoyage de piscine. Un appareil de nettoyage de piscine possède un boîtier, un mécanisme d'entraînement, une ou plusieurs roues et un élément d'entraînement. Le mécanisme d'entraînement comprend une transmission par engrenage et un moteur associés au boîtier. Le moteur alimente la ou les roues pour un déplacement dans une direction vers l'avant ou une direction vers l'arrière et permet d'orienter les roues. Le moteur alimente également l'élément d'entraînement (par exemple, un élément d'entraînement rotatif tel qu'une hélice, une roue à ailettes, un ventilateur, un rotor, un ventilateur aspirant) vers une position/un état MARCHE et ARRÊT pour propulser l'appareil de nettoyage de piscine. Des modes de réalisation concernent également des systèmes/procédés d'entraînement d'un appareil de nettoyage de piscine.
