Water removal device

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.

What is claimed is: 
     
         1 . A water removal device to withdraw water from the horizontally disposed elongated trough of a drain formed in the bottom of a swimming pool comprising a horizontally disposed elongated lower suction or vacuum housing disposed adjacent the bottom of the swimming pool and configured to be at least partially disposed within the length of the horizontally disposed elongated trough, said horizontally disposed elongated lower suction or vacuum housing including a plurality of perforations or holes formed along the length thereof to receive water from the elongated trough and a separate upper suction or vacuum source independent of the pool pump to create a suction or vacuum to draw water from the bottom of the swimming pool upwardly from the elongated trough through said perforations or holes into and through said horizontally disposed elongated lower suction or vacuum housing to remove the water from the swimming pool, said horizontally disposed elongated suction or vacuum housing comprises a horizontally disposed elongated lower suction or vacuum chamber cooperatively formed by a horizontally disposed elongated arcuate or convex bottom wall having a plurality of intake perforations or holes formed therethrough, a substantially vertical flat side wall extending upwardly from each side of said horizontally disposed elongated arcuate or convex bottom wall, a substantially vertical flat end wall extending between corresponding ends of said substantially vertical flat side walls and a top wall having an outlet port formed therethrough extending over the upper portions of said substantially vertical flat side walls and said substantially vertical flat end walls. 
     
     
         2 . The water removal device of  claim 1  wherein each said substantially vertical flat end wall includes a plurality of intake perforations or holes. 
     
     
         3 . The water removal device of  claim 1  wherein said upper suction or vacuum source is detachable coupled to said horizontally disposed elongated lower suction or vacuum housing by an intermediate hollow coupling sleeve including a lower wall. 
     
     
         4 . The water removal device of  claim 3  wherein each said substantially vertical flat end wall includes a plurality of intake perforations or holes. 
     
     
         5 . The water removal device of  claim 3  wherein a flow aperture is formed in said lower wall of said intermediate hollow coupling sleeve disposed in alignment with said outlet port formed in said top wall of said horizontally disposed elongated lower section or vacuum housing to drain water from the trough through said intake perforations or holes through said outlet port and said flow port to said intermediate hollow substantially cylindrical coupling sleeve. 
     
     
         6 . The water removal device of  claim 5  wherein a sealing ring or flange is disposed between the lower portion of said upper suction or vacuum and said intermediate hollow coupling sleeve to form a seal therebetween to maintain the suction or vacuum between the trough of the drain and said upper suction or vacuum source. 
     
     
         7 . The water removal device of  claim 1  wherein said horizontally disposed elongated lower suction or vacuum housing and said upper suction or vacuum source comprise a single unitized device or unit. 
     
     
         8 . The water removal device of  claim 1  wherein a substantially horizontal lip or support shelf is formed on the upper portion of each said substantially vertical flat side wall and said lower vacuum housing intake or outside drain, said outside diameter of the lower vacuum housing being greater than the distance between said substantially vertical flat side walls such that said intermediate coupling sleeve rests on said lips or support shelves to hold said water removal device in spaced relationship relative to the bottom of the trough. 
     
     
         9 . A water removal device to withdraw water from the horizontally disposed elongated trough of a drain formed in the bottom of a swimming pool comprising a horizontally disposed elongated lower suction or vacuum housing disposed adjacent the bottom of the swimming pool and configured to be at least partially disposed within the length of the horizontally disposed elongated trough, said horizontally disposed elongated lower suction or vacuum including a plurality of perforations or holes formed along the length thereof to receive water from the elongated trough and a separate upper suction or vacuum source to create a suction or vacuum independent of the pool pump to draw water from the bottom of the swimming pool upwardly from the elongated trough through said perforations or holes into and through said horizontally disposed elongated lower suction or vacuum housing to remove the water from the swimming pool, said horizontally disposed elongated suction or vacuum housing comprises a horizontally disposed elongated lower suction or vacuum chamber cooperatively formed by a horizontally disposed elongated arcuate or convex bottom wall having a plurality of intake perforations or holes formed therethrough, a substantially vertical flat side wall extending upwardly from each side of said horizontally disposed elongated arcuate or convex bottom wall, a substantially vertical flat end wall extending between corresponding ends of said substantially vertical flat side walls and a top wall having an outlet port formed therethrough extending over the upper portions of said substantially vertical flat side walls and said substantially vertical flat end walls. 
     
     
         10 . The water removal device of  claim 9  further including a plurality of protrusions extending from said horizontally disposed elongated lower section or vacuum housing to engage the trough to support the water removal in spaced relation thereto. 
     
     
         11 . A water removal device to withdraw water from the horizontally disposed elongated trough of a drain formed in the bottom of a swimming pool comprising a horizontally disposed elongated lower suction or vacuum housing disposed adjacent the bottom of the swimming pool and configured to be at least partially disposed within the length of the horizontally disposed elongated trough, said horizontally disposed elongated suction or vacuum housing comprises a horizontally disposed elongated lower suction or vacuum chamber cooperatively formed by a horizontally disposed elongated arcuate or convex bottom wall, a side wall extending upwardly from each side of said horizontally disposed elongated arcuate or convex bottom wall, an end wall formed on each opposite end portion of said water removal device said horizontally disposed elongated suction vacuum housing having at least one hole formed therein to receive water from the horizontally disposed elongated trough drain by an upper suction or vacuum. 
     
     
         12 . The water removal device of  claim 11  wherein each said end wall includes at least one hole. 
     
     
         13 . The water removal device of  claim 12  wherein said elongated arcuate or convex bottom wall includes at least one intake hole formed therethrough. 
     
     
         14 . The water removal device of  claim 13  wherein said elongated arcuate or convex bottom wall includes a plurality of intake holes. 
     
     
         15 . The water removal device of  claim 14  wherein each said end wall includes a plurality of intake holes. 
     
     
         16 . The water removal device of  claim 12  wherein each said end wall includes a plurality of intake holes.
