Swimming pool cleaning vehicle

Abstract

Disclosed herein is a swimming pool cleaning vehicle including a housing having an outer shell and defining a hollow interior. The housing having at least one intake port and at least one outlet port. The intake port(s) being located adjacent the drive mechanism. The pool cleaning vehicle includes a drive mechanism which in different embodiments has pairs of wheels and / or rollers and various combinations thereof for moving the vehicle. The vehicle includes a bottom and the bottom is concaved inwardly toward the interior.

Description

FIELD OF THE INVENTION[0001]This invention relates to the field of swimming pool cleaning vehicles, and more particularly the invention relates to improvement on its bottom design for preventing the swimming pool cleaning vehicle from becoming stuck or hung as it runs along the floor of the swimming pool from various floor obstacles.BACKGROUND OF THE INVENTION[0002]Existing swimming pool cleaners can be classified by the means for moving the cleaner along the pool, for example wheel, roller, belt or hydraulic propulsion type. Prior art construction is illustrated in FIG. 1 which consists of the following: an exterior body (100) which forms a hollow interior (110), at least one intake port (120) located on the said body (100); at least one filter bag (130) filtering water receiving from intake port (120). The filter bag is located inside the hollow interior (110) of the body (100); at least one outlet port (140) located on the body (100) and at least one water pump (150) placed under...

AI Technical Summary

Benefits of technology

[0018]It is an advantage of the swimming pool cleaning vehicle in accordance with invention to overcome obstacles on the pool surface while operating without affecting the partial vacuum and water flow required at water inlet port.

[0019]It is another advantage of the swimming pool cleaning vehicle in accordance with invention to efficiently suck up dirt and debris into the swimming pool cleaning vehicle filter bag.

Problems solved by technology

Since swimming pool cleaner has to suck water in through this intake port, the intake port cannot have floor clearance which is too high.

If it is too high, debris set at swimming pool floor cannot be picked up by the limited partial vacuum and water flow generated by the water pump.

Swimming pools of such construction naturally have an uneven pool floor causing the typical swimming pool cleaner to become stuck or at least not run normally or cause extra drive motor wear caused because of slippage, which prevents the swimming pool cleaner from operating normally, and even running the risk of being hit and damaged, causing higher defective rate and higher maintenance cost.

One drawback to such a skirt is that it could be caught by uneven swimming pool floor.

On the other hand, a non-closed skirt cannot limit the water flow and therefore cannot generate enough partial vacuum and flow rate to bring debris and segregated dirt up to be filtered.
