(1) Field of the Invention
The present invention relates generally to valving mechanisms. More particularly, the invention concerns a device for use in waste lines and the like which permits fluids to flow freely into the drain of the waste line, but positively prevents gases.
(2) Background
Human excrement smells unpleasant and, unless carefully disposed of, transmits diseases. A major development in the disposal of human excrement was Sir Thomas Crapper's water closet, which has hardly changed unto this day.
Essentially, excrement is deposited into a bowl of water coupled to a sewage pipe by a U shaped tube. The sudden emptying of a large quantity of water into the bowl causes the contents thereof to be flushed through the U tube into the sewage pipe. The U tube remains full of water and prevents noxious smells from the sewage pipe from permeating back into the water closet.
Unfortunately, users of water closets or toilets, themselves, may release quantities of gases together with waste products. Additionally, if the toilet is not flushed frequently, as may be the case during water shortages, and the like, or until flushed, the contents thereof may release foul smells into the air within the generally small confines of the toilet.
Preferably, toilet rooms should be well ventilated with a window to the outside. In practice, this is not always possible, and often, to save space, toilets are positioned under staircases and in other places, where windows are not possible. An alternative solution is to provide a duct to the outside, and to use an extractor fan to pump air into such a duct. Such a duct is usually positioned in or near the ceiling. For privacy, toilet windows are usually small and positioned high up as well. The problem with both windows and such extractor fans is that the gases have to diffuse, typically by Brownian motion, throughout the small confines of the toilet. In consequence thereof, such gases may be inhaled by users. Particularly in public places where the number of users of toilets is large, windows or extractor fans of the types discussed here above are not ideal solutions.
A technology describes a toilet ventilating system for use with a bowl incorporating a sewer line connection and including an upstanding vent conduit leading from the bowl rim outlets to an elevated cross over in the water storage tank and then dropping downwardly to form an exhaust conduit connected with the sewer connection. A centrifugal fan having a flow rate of 60 cubic feet per minute is incorporated in the vent conduit and a trap valve is incorporated in the cross over for selectively opening and closing communication between the vent conduit and the exhaust conduit. The trap valve incorporates a floating cylinder, the positioning of which is controlled by water pumped from an elevated reservoir through a positive displacement pump. A controller is provided for controlling the positive displacement pump to open the trap valve, actuation of the centrifugal fan and closure of the trap valve, deactivation of the fan and actuation of the flush valve.
The system is designed for use with mono-block type toilets, and has a relatively complicated mechanism for venting odors to the sewage line after the u shaped trap.
Another, describes a toilet assembly having an automatic ventilation system which includes a high-powered suction member, an innovative motion sensor, a siphonic action member, and discharging member for objectionable odor. While the user sits on the toilet seat ring, the objectionable odor is effectively ventilated. When the user stands up and pushes a flush push button, the toilet assembly is effectively flushed.
The mechanism described includes sensors and electromagnets and is complicated and not too reliable.
The solution described is advantageous in that everything is coupled to the toilet seat and can be retrofitted onto a wide range of standard toilets. However, the solution is complicated and inherently unreliable. An air treatment assembly box is provided to the side and below the position where the bowl and tank are joined. Conduit pipes run along the seam coupling the bowl and tank. Urine from males with poor aim will tend to run along the outside of the conduits to the box. cl BRIEF SUMMARY OF THE INVENTION
Primarily the invention is a trap assembly for draining waste water toward sewer pipes while blocking back flow of odors.
In a preferred embodiment the trap assembly comprises of a housing having a hollow interior, open, upper and lower ends. The housing is connected to a drain pipe at the lower end and extending outwardly therefrom into a substantially vertical orientation, a valve member formed of buoyant material; a retainer assembly connected to said housing in an at least partially supporting relation to a valve member. Further the valve member disposable into and out of sealing engagement with the valve seat dependent on direction of liquid flow along a flow path.
Further the housing of the trap assembly for draining waste water toward sewer pipes while blocking back flow of odors further comprises of a head assembly removably secured within the upper end of the housing, the head assembly includes a hollow interior and open proximal and distal ends.
Also, according to the invention the valve member is movably contained within the housing and along the flow path. Further, the retainer assembly is disposed to normally retain said valve member out of said flow path.
