Benefits of technology

[0018]Still another feature of the invention is an environmentally sensitive, i.e. “green” waterless, non-flush urinal system that is closed in the non-use mode to eliminate odor release, a problem associated with conventional systems relying on oil seals.

Problems solved by technology

The system is environmentally sensitive in that it does not consume the water required by conventional flush toilet systems, and the adverse effects of oil being transferred to the waste treatment facilities.

first embodiment

[0032]The present invention, which is illustrated in the FIGS. 2-4, 5A, 5B, 6A and 6B, will show how these various shortcoming are overcome. From these Figures, where common reference numerals represent like components or features throughout the various views, the advantages hereof will become evident.

[0033]FIG. 2 is a side view of the waterless urinal system 30 of this invention, where the system consists of an upstanding housing 32 that may be fabricated of a stainless steel or porcelain body 34. Additionally, the housing 32 includes a central concave portion 40 containing a deep recess 16, for reasons to become apparent hereinafter. The base of the recess 40 includes a central opening 42 in fluid communication with a drain line 17 and air relief line 46. Finally, unlike the commercial prior art system, the system hereof has two operating modes, namely, an “opened” or use mode, and a “closed” or non-use mode. These operating modes are controlled by a motion control system 36, as k...

second embodiment

[0036]FIGS. 6-7 show details for the cartridge and housing of the second embodiment according to this invention. The cartridge includes a generally circular housing body 72 having a central opening 74 and an off-set opening 76, as later discussed. Additionally, about the inside wall 78 thereof, a flexible strip containing a series of LED's may be provided. These LED's, as later explained, may be lighted to designate a ‘target’ for the user, where a preferred color is green. Finally, the upper peripheral edge 81 includes an annular recess 80 for sliding receipt of a cover member 82.

[0037]The cover member 82 is characterized by an annular rim 84 that overrides the upper peripheral edge 81 to form a unitary structure. The cover member 82 is further characterized by a central recess 84 having a downwardly tapered wall 86 terminating in a central opening 88 that may include a female key to maintain its position, i.e. not spin. The tapered wall 86 may be fabricated of a translucent or tra...

Abstract

An electronic, dual valve normally closed, mechanical sealed waterless urinal system, free of oil sealing, where the system may be mounted to the wall of a restroom facility. The system includes a bowl portion that features a central recess in communication with a drain or sewer line. A circular housing, sized for sliding receipt within the central recess, mounts a cartridge containing first and second chambers. A first chamber includes a latching solenoid piston rod vertically movable into sealing engagement with the top drain opening in the housing. Further, the first chamber includes a flexible, one-way valve to allow the passage of fluid therethrough, while preventing gases from entering the first chamber. The second chamber includes a solenoid operable to move the piston rod to an opened position, where the latching solenoid is automated by a motion sensor control mechanism, and mechanical means to return the piston rod to a closed position. In a second embodiment, the system includes a latching hybrid solenoid mechanism. Finally, the system may include a series of LED's, preferably emitting a continuous or intermittent green light, and a UV light source to help sanitize the cartridge.

Description

RELATED APPLICATION[0001]This application relates to and claims priority of Provisional Application, Ser. No. 60 / 932,700, filed Jun. 1, 2007, under the title, Waterless Urinal, by the inventor hereof, where the contents are incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention is directed to the field of waterless or non-flush urinals for use in commercial, residential and public facilities, more particularly for an electronic replacement cartridge that relies upon a pair of mechanical seals for such urinals that does not require oil seals for odor trapping of fluids. The cartridge hereof can be designed to fit all existing waterless urinal housings with liquid sealant or Duck Bill flexible membranes.BACKGROUND OF THE INVENTION[0003]This invention is directed to a dual mechanical drain seal cartridge for use in a “green” waterless or non-flush urinal, particularly for reception within a cartridge housing associated with the urinal bowl. W...
