Portable siphon effect vacuum cleaning device for liquid filled vessels

Abstract

The present invention is a portable siphon effect vacuum cleaning device for the collection and removal of debris from liquid filled vessels. The invention comprises a handle structure to grip and control the invention in combination with at least one priming conduit and associated liquid communication path to direct the flow of liquid and debris to a desired discharge location, where priming conduit includes a suction end, discharge end, and a restricting valve positioned between, and through the action of gripping the handle and pushing and pulling in the axial direction, one can incrementally fill the liquid communication path until a continuous siphon flow of liquid begins, in turn realizing the benefits of creating a continuous flow of liquid to provide a continuous suction effect for continuous collection and expulsion of debris without any need for continual manual or powered pumping of that liquid.

Description

FIELD OF INVENTION[0001]The present invention relates to portable vacuum cleaning devices for liquid filled vessels, more particularly to portable siphon effect vacuum cleaning devices for liquid filled vessels that include water filled spas, hot tubs and swimming pools.BACKGROUND AND OBJECTS OF THE PRESENT INVENTION[0002]There are many known portable vacuum cleaning devices that generate suction for cleaning liquid filled vessels, however such known devices either require substantial or continual manual pumping to provide the suction needed for cleaning, such as the Goble U.S. Pat. No. 4,944,101, or ones that require a pressurized liquid supply to generate the suction, such as the Templin U.S. Pat. No. 10,267,536, or alternatively, the use of an unpowered siphon flow of liquid using the liquid within the vessel for the siphon and in turn a suction effect for cleaning as taught in the Lynch U.S. Pat. No. 4,797,206.[0003]The present invention preferably utilizes the unpowered siphoni...

AI Technical Summary

Benefits of technology

The present invention is an improved vacuum cleaning device for use in liquid-filled vessels. It allows operators to pre-locate and pre-arrange the debris discharge area before generating a siphon. It simplifies the process of generating a siphon and allows for continuous vacuum cleaning without the need for continuous pumping. It also allows for suspension of sediment and debris to settle for a more efficient and thorough cleaning. The invention provides the ability to vacuum clean a vessel with or without a pumping system. It allows for attachment of a debris capturing device to prevent unwanted debris from being left behind or retrieval of lost objects. The invention increases vacuuming power and allows for a more desirable or required location for debris discharge. Overall, the invention improves the efficiency and effectiveness of vacuum cleaning operations.

Problems solved by technology

With siphon cleaning devices such as these, requiring the submersion and filling of components, difficulty can occur when air becomes trapped within the higher areas of the components being submerged in turn requiring the operator to push, tip and adjust the components in an attempt to force the trapped air out through one of the openings in the device to eventually allow for sufficient filling of the components with a liquid volume sufficient enough to enable the start of a siphon.

Then to initiate the siphon, even more difficulty can occur because the operator must now attempt to remove and relocate the discharge end of the downstream liquid communication conduit to the desired or even required discharge location outside the vessel plus at an elevation below liquid level while at the same time retaining the sufficient amount of captured liquid volume within the components to be able to initiate the siphon, all while keeping the suction end fully submerged within the vessel liquid.

This can be difficult to perform and can require multiple attempts or even multiple operators to execute, and may be too difficult to accomplish by one limited in flexibility or mobility.
