AI Technical Summary

Benefits of technology

"The swimming pool cleaning device is a device that can be used to clean a swimming pool by drawing water from the pool and cleaning the floor. It includes two suction tubes that are connected to a pump to create a vacuum to clean the pool. A flapper valve controls the water flow and allows the device to move along the pool surface without needing further user assistance. The device also has a base plate that reduces turbulence and an outer housing for protection. Additionally, a buoyant member is attached to the housing to make it easier for the device to move on the pool floor. Overall, the swimming pool cleaning device provides an efficient and effective way to keep a swimming pool clean."

Problems solved by technology

Such systems, however, are inefficient and their multiplicities of moving parts cause them to be vulnerable to misalignments and other mechanical failures.
Further, such systems tend to create vortices, turbulence and other negative fluid flow effects, which will obstruct the movement of the cleaning head and can cause the cleaning head to become dislodged from the floor of the swimming pool.

Embodiment Construction

[0016]The swimming pool cleaning device 10, shown in FIG. 1, cleans and purifies water contained within a large, manmade receptacle, such as a swimming pool, and further cleans the submerged surfaces of the receptacle. The upper end of the swimming pool cleaning device 10 includes a connector 240 for connection with a pressurized tube or hose. The tube or hose is connected to a conventional pump and purification system, as is often associated with the cleaning of swimming pools. The water is drawn out of the swimming pool by the pump, delivered to the purification system, and then returned to the swimming pool, once cleaned. Preferably, connector 240 is threaded, for connection to a conventional threaded hose, although any suitable connector may be utilized, dependent upon the nature of the tube or hose.

[0017]Water from the swimming pool is drawn through the lower portion of device 10, as indicated by directional arrows 270. As will be described in greater detail below, the water is...

Abstract

The swimming pool cleaning device is a submergible structure for drawing water from a tank, such as a swimming pool, to be cleaned, and further for cleaning a submerged surface of the tank, such as the swimming pool floor. The swimming pool cleaning device includes a pair of suction tubes, which communicate with a pressurized source, such as a pump, to suck water from the swimming pool for cleaning and later return to the swimming pool. A flapper valve controls entry of water into the suction tubes, alternating water flow between one tube and the other. The oscillatory flow between the two suction tubes imparts horizontal momentum to the swimming pool cleaning device, allowing the swimming pool cleaning device to travel along a surface of the pool without further user-provided motive force.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 759,618, filed Jan. 18, 2006.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to devices for cleaning tanks, pools, and other large water reservoirs, and particularly to a swimming pool cleaning device that provides a submergible structure for drawing water from the swimming pool while cleaning the swimming pool floor.[0004]2. Description of the Related Art[0005]A wide variety of systems have been utilized for cleaning swimming pools. Such systems typically include some sort of cleaning head, which is submerged within the swimming pool and rests on the pool bottom. An upper portion of the system is connected to an external pump, which provides suction to remove water from the pool for filtration and subsequent reentry into the swimming pool. The head of the device not only provides a suction head for the remov...
