Benefits of technology

The present invention is about a device that removes water from a swimming pool. It consists of a trough in the bottom of the pool and a vacuum device to remove the water from there. The vacuum device has a housing with intake holes and an outlet port to drain the water from the pool through the intake holes and out through the outlet port. The device can be easily attached to the pool's drain using a coupling sleeve. The technical effect of this invention is to provide a simple and efficient way to remove virtually all water from a swimming pool.

Problems solved by technology

Unfortunately there are no such devices capable of removing virtually all the water from a swimming pool with acceptable efficiency.

Embodiment Construction

[0024]As shown in FIGS. 3 through 7, the present invention relates to a water removal device generally indicated as 10 to withdraw virtually all the water W from the pool drain generally indicated as 12 formed in the bottom 14 of a swimming pool 16. As shown in FIGS. 1 and 2, the pool drain 12 comprises a trough 18 including a side wall 20 extending upwardly from each side of an arcuate or concave bottom wall 22 terminating in a lip or support shelf 24 formed on the upper position thereof to removably support a grate 26 thereon.

[0025]As shown in FIGS. 3 and 7, the water removal device 10 comprises an elongated lower suction or vacuum housing generally indicated as 28 configured to be at least partially disposed within the trough 18 during operation of the water removal device 10 and an upper suction or vacuum source generally indicated as 30 in fluid communication with the trough 18 through the elongated lower suction or vacuum housing 28 to selectively create a suction or vacuum wi...

Abstract

A water removal device to withdraw virtually all the water from the drain in the bottom of a swimming pool comprising an elongated lower suction or vacuum housing including a plurality of perforations or holes formed therein to receive water from a pool drain and an upper suction or vacuum source to create a suction or vacuum to draw water from the pool drain through the perforations or holes into and through the lower suction or vacuum housing to remove the water from the pool drain.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]A water removal device to withdraw the water from a drain in the bottom of a swimming pool.[0003]2. Description of the Prior Art[0004]Numerous devices have been designed to aid in removing water from bottom of a swimming pool. Unfortunately there are no such devices capable of removing virtually all the water from a swimming pool with acceptable efficiency. Several examples of vacuum devices are discussed below.[0005]U.S. Pat. No. 1,601,774 shows a vacuum tool comprising a hollow cylinder closed at each end having a channel suction member disposed therein.[0006]U.S. Pat. No. 4,443,899 relates to a vacuum cleaning system for a therapeutic tub that utilizes an aerating intake for jet nozzles located around the tub. A vacuum hose is connected to the air intake to draw in air. A vacuum head connected at the other end of the hose is moved along the bottom and sides of the tub to draw in the water as well as leaves and debris...
