Abstract
A toilet bowl deodorizing, disinfecting and washing apparatus. In one variation, the apparatus includes a flexible enclosure that contains a bellows, a high-pressure reservoir, a liquid reservoir, and a plurality of nozzles. The bellows, liquid reservoir, and nozzles are selectively placed in fluid communication with the high-pressure reservoir. In use, the flexible enclosure is disposed beneath a toilet seat (or is itself a toilet seat). Deodorizing/disinfecting/washing liquid, which is contained in the liquid reservoir, is admitted to the high-pressure reservoir. When a person sits on the flexible enclosure, the bellows compresses air that is admitted to the high-pressure reservoir, thereby pressurizing the deodorizing/disinfecting/washing liquid that is contained therein. As the person gets off the flexible enclosure, the high-pressure reservoir is connected to the nozzles such that pressurized deodorizing/disinfecting/washing liquid is dispensed.
Description




FIELD OF THE INVENTION




The present invention relates generally to a deodorizing and disinfecting device for bathrooms. More particularly, the present invention relates to a deodorizing and disinfecting device for use with toilets.




BACKGROUND OF THE INVENTION




Toilets are known to be sources of unpleasant odors. To this end, a variety of toilet-deodorizing devices have been proposed.




Existing toilet-deodorizing devices typically include a pump that circulates odoriferous air through odor-adsorbing material. These devices vary in effectiveness and usually have some shortcomings.




SUMMARY OF THE INVENTION




A toilet bowl deodorizing, disinfecting and washing apparatus is disclosed. In one variation, the apparatus includes a flexible enclosure that contains a flexible air chamber or bellows, a high-pressure reservoir, a liquid reservoir, and a plurality of nozzles. The bellows, liquid reservoir, and nozzles are selectively placed in fluid communication with the high-pressure reservoir by the action of an actuating/valving system.




In use, the flexible enclosure is disposed beneath a toilet seat (or is itself a toilet seat). Deodorizing/disinfecting/washing liquid, which is contained in the liquid reservoir, is admitted to the high-pressure reservoir. When a person sits on the flexible enclosure, the bellows compresses air. The compressed air is admitted, by the action of the actuating/valving system, to the high-pressure reservoir, thereby pressurizing the deodorizing/disinfecting/washing liquid that is contained therein. The actuating/valving system prevents the pressurized liquid from being delivered to the nozzles.




As the person gets off the flexible enclosure, the actuating/valving system places the high-pressure reservoir in fluid-communication with the nozzles such that pressurized deodorizing/disinfecting/washing liquid is dispensed.

DETAILED DESCRIPTION




For context,

FIG. 1

depicts a standard toilet including bowl


101


and toilet seat


102


(tank and seat cover not shown). Seat


102


includes hinge


104


, by which the seat is pivotally connected to toilet bowl


100


. In a variation of the illustrative embodiment that is depicted in

FIG. 2

, toilet bowl deodorizing and disinfecting apparatus


206


is inserted between seat


102


and bowl


100


. In another variation, toilet bowl deodorizing and disinfecting apparatus


206


is itself the toilet seat. The configuration of either of these variations of apparatus


206


is substantially the same.





FIG. 3

depicts a view of the exterior of toilet bowl deodorizing and disinfecting apparatus


206


. As depicted in

FIG. 3

, apparatus


206


includes flexible enclosure


308


that has a shape that is substantially in the form of a toilet seat. In the variation depicted in

FIG. 3

, flexible enclosure


308


is “pleated,” accordion style, to assure flexibility. Other configurations known to provide flexibility can suitably be used. Brackets


310


depending from the rear of flexible enclosure


308


are used to attach it to toilet bowl


100


.




A plurality of orifices


312


are located along inner circumference


314


of flexible enclosure


308


. Deodorizing liquid, washing liquid or disinfecting liquid (hereinafter collectively referred to in this Specification as “deodorizing liquid”) is dispensed from the interior of flexible enclosure


308


through orifices


312


.





FIG. 4

depicts a view of the interior of toilet bowl deodorizing and disinfecting apparatus


206


. Inside of flexible enclosure


308


are liquid reservoir


420


, flexible air chamber or bellows pump


424


, high-pressure reservoir


428


, and nozzles


434


, interconnected as shown.




Liquid reservoir


420


receives and stores deodorizing liquid. Liquid reservoir


420


is charged with deodorizing liquid via filling orifice


416


. Conduit


418


(e.g., tubing, etc.) carries the deodorizing liquid to liquid reservoir


420


. Conduit


422


(e.g., tubing, etc.) carries deodorizing liquid from liquid reservoir


420


to high-pressure reservoir


428


.




When flexible air chamber or bellows pump


424


is compressed, such as when a person sits on flexible enclosure


308


(or a toilet seat that rests on top of flexible enclosure


308


), air within flexible air chamber


424


is compressed. The compressed air is directed to high-pressure reservoir


428


via conduit


426


(e.g., tubing, etc.), thereby pressurizing the deodorizing liquid within.




Pressurized, deodorizing liquid from high-pressure reservoir


428


is delivered, via conduit


432


(e.g., tubing, etc.) to nozzles


434


. The nozzles, which align with orifices


312


, produce a fine, directional mist


436


from the pressurized deodorizing liquid. Mist


436


is directed through orifices


312


towards the bottom of the toilet bowl. Nozzles suitable for creating a directional mist are available from Misty Mate Company of Gilbert, Ariz. (see, www.Mistymate.com). Nozzles


434


are advantageously directionally adjustable to accommodate various types and shapes of toilet bowls. This directional adjustability can be implemented, for example, by introducing a small pliable tube inside conduit


432


that leads to nozzle


434


or in other ways known to those skilled in the art. A screw-type in-line “choker” can be used to provide flow regulation.




As indicated above, various charging and dispensing operations occur during use of toilet bowl deodorizing and disinfecting apparatus


206


. These operations are controlled by an actuating/valving system, such as system


538


, which is depicted in

FIGS. 5-7

. Illustrative actuating/valving system


538


includes actuating element


430


, cylindrical body


540


, piston


542


having passageway


544


, check valve


546


and spring


550


, interrelated as shown.




Actuating/valving system


538


advantageously provides the following functionality:




Selectively admits deodorizing liquid to enter high-pressure reservoir


428


.




Selectively admits pressurized air into high-pressure reservoir


428


.




Selectively releases pressurized deodorizing liquid to nozzles


434


. Illustrative actuating/valving system


538


is configured as a combined actuating/valving element. In other variations of deodorizing and disinfecting apparatus


206


, the actuating/valving system can be implemented as discrete actuating elements and valve elements, in known fashion.





FIG. 5

depicts actuating/valving system


538


in a state before a user has sat on flexible enclosure


308


. Actuating element


430


, which is rigidly linked to piston


542


, is in its top or un-depressed position or state. In this state, passageway


544


, which can be implemented as a groove that is disposed near the surface of piston


542


, places liquid reservoir


420


in fluid communication with high-pressure reservoir


428


. More particularly, in the illustrative embodiment, passageway


544


places the portion of conduit


422


that is located upstream of actuating/valving system


538


(i.e., portion


422




a


) in fluid communication with the portion of conduit


422


that is located downstream of actuating/valving system


538


(i.e., portion


422




b


). Consequently, deodorizing liquid from liquid reservoir


420


flows through passageway


544


, past optional check valve


552


and into high-pressure reservoir


428


.




When a downward-directed force is applied to actuating element


430


, such as is the result of a user sitting on flexible enclosure


308


, actuating element


430


and piston


542


moves downwardly in cylindrical body


540


. Since check valve


546


opens fully, piston


542


drops quickly. Actuating element


430


and piston


542


are depicted in a bottom or fully-depressed position or state in FIG.


6


.




The action of a user sitting down on flexible enclosure


308


also depresses flexible air chamber


424


. This compresses the air within chamber


424


. When piston


542


is at its bottom position, passageway


544


places flexible air chamber


424


in fluid communication with high-pressure reservoir


428


. More particularly, in the illustrative embodiment, passageway


544


places the portion of conduit


426


that is located upstream of actuating/valving system


538


(i.e., portion


422




a


) in fluid communication with the portion of conduit


422


that is located downstream of actuating/valving system


538


(i.e., portion


426




b


). Consequently, pressurized air from flexible air chamber


424


flows through passageway


544


, past optional check valve


554


and into high-pressure reservoir


428


.




As piston


542


drops, passageway


544


briefly places portions


432




a


and


432




b


of conduit


432


in fluid communication. Consequently, a very small amount of pressurized deodorizing liquid leaves high-pressure reservoir


428


. The amount of liquid escaping is so small that it is barely sufficient, at best, to prime conduit


432


. As shown in

FIG. 6

, when piston


542


is at its bottom position, liquid flow from liquid reservoir


420


is blocked, pressurized liquid flow to nozzles


434


is blocked, and spring


550


is compressed.




When the downward-directed force is withdrawn from actuating element


430


, spring


550


expands, moving actuating element


430


and piston


542


upward through cylindrical body


540


, as depicted in FIG.


7


. Piston


542


moves slowly upward, due to small orifice


548


in check valve


546


. With continued upward movement, passageway


544


places high-pressure reservoir


428


in fluid communication with nozzles


434


. More particularly, in the illustrative embodiment, passageway


544


places the portion of conduit


432


that is located upstream of actuating/valving system


538


(i.e., portion


432




a


) in fluid communication with the portion of conduit


432


that is located downstream of actuating/valving system


538


(i.e., portion


432




b


). Consequently, pressurized deodorizing liquid from high-pressure reservoir


428


is expelled through passageway


544


and to nozzles


434


where it is dispensed as fine, directional mist


436


.




The amount of time that the deodorizing liquid sprays from nozzles


434


, depends, in part, on the amount of time that portions


432




a


and


432




b


of conduit


432


are aligned. That amount of time is dependent upon the rate at which piston


542


rises. The rise rate of the piston is dependent upon the size of orifice


548


in check valve


546


(in addition to properties of spring


550


). It is within the capabilities of those skilled in the art to determine orifice size and spring properties to obtain a desired spray time.




When pressurized deodorizing liquid is dispensing from high-pressure reservoir


428


, check valves


552


and


554


, in addition to the position of passageway


544


, prevents pressurized deodorizing liquid from backing up into liquid reservoir


420


or flexible air chamber


424


.




It is to be understood that the above-described embodiments are merely illustrative of the invention and that many variations may be devised by those skilled in the art without departing from the scope of the invention and from the principles disclosed herein. For example, in embodiments in which cylindrical body is appropriately dimensioned, check valves


552


and


554


are probably not required. Furthermore, in yet additional embodiments, one or more additional liquid reservoirs can be included in deodorizing and disinfecting apparatus


206


. For example, in addition to the first liquid reservoir, which might contain a deodorizing liquid, a second liquid reservoir contains a disinfecting liquid. A third liquid reservoir might contain a cleaning liquid, etc. Modifying the illustrative embodiment to accommodate extra liquid reservoirs is within the capabilities of those skilled in the art. It is therefore intended that such variations be included within the scope of the following claims and their equivalents.
