Definitions
- Sanitation codes require urinals to provide an odor seal to contain gasses and odors which develop in the drain system: this function is conventional performed by the well known P-trap or S-trap in which the seal is formed by a residual portion of the flushing water.
- This seal effectively locks in sewer odors from the drain-pipe beyond the trap, however the upward-facing liquid surface communicates freely with the user environment, so that the crap must be kept free of residual urine by copious flushing to prevent unacceptable odor levels from the liquid in the crap; therefore a large amount of water is consumed in flushing these conventional urinals.
- conventional flushing type urinals and wafer-wasteful toilets held an unchallenged monopoly.
- threatened and real water shortages have aroused new environmental concerns and heightened conservation awareness as evidenced by the introduction of low flush toilets.
- a key parameter of oil-sealed odor traps for waterless urinals is the amount of sealant depletion that takes place under normal service conditions over periods of time and frequency of usage. Related to this is the possible partial or complete loss of sealant due to the abnormal condition of unnecessary but unavoidable high pressure flushing with water. While some modem oil-sealed odor traps are considerably improved over early versions, there remains an unfulfilled need for further improvements in the above-described aspects of sealant preservation.
- the odor trap is preferably configured such that it can be economically made from two molded plastic parts, i.e., a main compartment part and a cap/baffle part, that can be molded from plastic and joined by thermal bonding into a unit configured as a replaceable cylindrical cartridge that can be charged with sealant and sealed with a sticker for shipment so that upon Installation it is necessary only to install the cartridge and remove the sticker.
- FIG. 1 is a mid cross-sectional view of an odor trap 10A of the edge-entry trap configuration of known type for example as disclosed in DE 2 816 597 , configured as a cylindrical cartridge.
- urine from above near the outer edge separates into droplets that permeate through the layer of sealant 20 and then join the main body of urine 18 .
- additional urine enters the body of urine 18 , it overflows the stand pipe 14A and the over-flow portion gravitates down the drain.
- the component X labelled in the FIGS. Is an approximate average of the horizontal vector components X of the wastewater flow, extending from the middle of the entry opening (e.g. the point of average entry of the wastewater into the sealant) to a furthest point along the flow path (e.g, around the baffle) in which sealant recovery can occur.
- the invention contemplates a value X based on the approximate average, generally all of the wastewater will follow a flow path having a component X , e.g. any wastewater not following such a flow path would be insubstantial enough to effect the proper functioning of the invention -- such as if extraneous openings were provided allowing a minimal volume flow rate therethrough.
- a vertical vector component Y of the flow path can be approximately defined as the vertical distance from the top of stand pipe 14A to the bottom of baffle 16A . Accordingly, an alternative feature can be based on a ratio X/Y, which can be used to estimate an effective slope of the flow path - for example, X/Y ⁇ 1 indicating a predominantly vertical flow path and X/Y > 1 indicating a predominantly horizontal flow path.
- FIG. 5 depicts a center-antry odor trap 10E wherein the baffle is configured with a vertical upper portion 16A and a horizontal lower portion 16B flanged outwardly as shown. This creates a folded liquid path having upper portion 22A above and lower portion 22B as shown. Only the upper portion 22A will be effective in returning stray sealant because the baffle 16B is not sloped. Thus, stray sealant in the portion 22B will tend to get swept along to the right and escape to the drain along with the effluent.
- the horizontal recovery dimension X will be as indicated, derived from the upper flow path portion 22A .
- the enclosure can be, for example, dimensioned about 11.4 cm (4 1/2") in diameter and 7.0 cm (2 3/4") in height.
- the size of the trap is to be limited.
- the diameter of the trap is preferably between 5.0 to 6.4 cm (2 to 2 1 ⁇ 2 inches).
- It is preferably molded from polyethylene, or from another suitable plastic material such as polypropylene, ABS or polystyrene, to provide a smooth stain-resistant surface.
- the material can also include a fiberglass reinforced polyester. Other suitable materials can also be utilized.
- the main container 14 and cap/partition part 16 are molded as separate parts and then bonded together to form an integral enclosure, sines access to the interior is not normally required.
- the inlet and outlet locations and the baffle configuration, etc. result in a predominantly horizontal flow
- the preferred embodiments of the present invention yield values of X/R > 30%, as distinguished, for example, from predominantly vertical flow of known art in the above table.
- the present invention can even yield values greater than 50%, allowing for a wide margin above the 15% estimated for the noted prior art.
- the present invention provides values of X/Y of greater than 1.0, while the above-noted estimate of the noted prior art achieves a value substanlially less than 1.0.
- a tubular drain stand 14C is provided which extends upward at the right hand side of the floor 14B .
- the top edge of the drain stand 14C defines the overflow level of the container.
- the two liquid flow paths 22A and 22B shown provide a corresponding recovery path dimension X similar to that shown in FIG. 12 -- e.g., the sum X1 + X2 from the paths 22A and 22B , respectively.
- a body of wastewater 18 has a sealant layer 18 buoyantly floating thereon.
- the bottom member 170 includes a perimeter wall 171 , a bottom wall 172, and a upwardly extending drain stand 173.
- the drain stand preferably is a cylindrical tube extending above the wall 171 with an upper opening 175 and a lower opening 176 .
- the lower edge of the bottom member can, for example, as shown include a tapered wall 174.
