Claims (23)
- A drain odor trap adapted to contain in operation a body of wastewater acting as an odor seal against sewer gasses, the trap comprising:a main container (14) having a baffle (16A, 16B) therein and having at least one entry opening (16D) through which generally all of the wastewater enters the main container; an entry compartment receiving said wastewater andcommunicating with an adjacent discharge compartment beneath said baffle (16A, 16B);a drain stand (14A), formed in the discharge compartment, having an upper edge defining an overflow level of the container and having a bottom outlet adapted to communicate with an external drain;a layer of low density sealant (20) floating on a portion of the wastewater body in said entry compartment of the trap and acting as an odor seal against odor from the contained wastewater;said entry opening (16D) and said baffle (16A, 16B) being arranged to provide a fluid flow path (22) through the trap of generally all wastewater entering the trap, andsaid main container (14) having a dimension (R) at a height at a bottom end of the baffle (16A, 16B), from the center of the container to a side thereof,
said liquid flow path (22) defines a horizontal component length (X) along which stray sealant is buoyed up and returns to the sealant layer (20), the horizontal component length (X) being the horizontal component of travel of wastewater in the flow path from the middle of the entry opening (16D) to the bottom end of the baffle (16A, 16B), wherein the horizontal component length (X) is greater than 30 % of said container dimension (R). - A drain odor trap adapted to contain in operation a body of wastewater acting as an odor seal against sewer gasses, the trap comprising:a main container (14) having a baffle (16A, 16B) therein and having at least one entry opening (16D) through which generally all of the wastewater enters the main container; an entry compartment receiving said wastewater andcommunicating with an adjacent discharge compartment beneath said baffle (16A, 162);a drain stand (14A), formed in the discharge compartment, having an upper edge defining an overflow level of the container and having a bottom outlet adapted to communicate with an external drain;a layer of low density sealant (20) floating on a portion of the wastewater body in the entry compartment and acting. as an odor seal against odor from the contained wastewater;said entry opening (16D) and said baffle (16A, 16B) beingarranged to provide a fluid flow path (22) through the trap of generally all wastewater entering the trap,
said liquid flow path (22) defines a horizontal component length (X) along which stray sealant is buoyed up and returns to the sealant layer (20), the horizontal component length (X) being the horizontal component of travel of wastewater in the flow path from the middle of the entry opening (16D) to the bottom end of the baffle (16A, 16B), wherein the horizontal component length (X) is larger than a vertical distance (Y) measured from said overflow level to the bottom end of said baffle (16A, 16B). - The odor trap of claim 1 or 2, wherein said at least one opening (16D) is formed in a top surface (16C) of the container.
- The odor trap of claim 1 or 2, wherein the baffle comprises a vertical portion (16A) extending downwardly into said container (14) from a top surface (16C) thereof and separating said container into said entry compartment and said discharge compartment.
- The odor trap of claim 4, wherein the baffle further comprises a non-vertical portion (16B) extending toward the entry compartment or toward the discharge compartment from the lower end of said vertical portion (16A).
- The odor trap of claim 1 or 2, wherein the baffle comprises a non-vertical portion (16B) extending downwardly into said container (14) from a top surface (16C) thereof and separating said container into said entry compartment and said discharge compartment.
- The odor trap of claim 1 or 2, wherein the at least one opening (16D) is provided at a central region in the top surface (16C) of the trap, the central region being intersected by the central axis (D-D')of the trap.
- The odor trap of claim 5, 6 or 7, wherein said non-vertical portion (16B) of said baffle is sloped in a manner to cause stray low density sealant droplets to rise buoyantly from said liquid flow path (22) beneath said non-vertical portion to be directed back to said layer of sealant (20).
- The odor trap of any one of the 1 to 8, wherein said horizontal component length (X) is the entire horizontal component of wastewater travel directly beneath at least one of said layer of sealant(20) and, when present, a sloped portion (16B) of said baffle.
- The odor trap of any one of the claims 3 to 9, when depending from claim 1, wherein the main container (14) is generally cylindrical and said container dimension (R) is the radius thereof.
- The odor trap of claim 10, wherein said radius (R) is in the range of 5.0 to 6.4 cm (2 to 2.5 inches).
- The odor trap of any one of claims 1 to 11, wherein said container includes a shelter region (T) in an upper portion thereof adjacent said at least one entry opening (16D), said shelter region (T) accepting low-density sealant temporarily displaced by water flushed into said trap following said flow path (22), thereby sheltering the displaced sealant and preventing sealant loss.
- The odor trap of claim 12, wherein a top cover (16C) of said container is sloped downward with said at least one entry opening (16D) at a lower end of the slope and said shelter region (T) is located below an upper region of the slope.
- The odor trap of claim 12, further including an air vent (16F) in said upper region of the top cover (16C) above said shelter region (T).
- The odor trap of any one of the claims 1 to 14, wherein said main container (14) is made of a plastic material.
- The odor trap of claim 15, wherein the container (14) is molded from a plastic material selected from a group including polyethylene, polypropylene and fiberglas-reinforced polyester.
- The odor trap of any one of the claims 1 to 16, wherein said low-density sealant (20) is an oily liquid.
- The odor trap of any one of claims 1 to 16, wherein the low-density sealant (20) is an aliphatic alcohol, in particular an aliphatic alcohol having 9 to 11 carbon atoms in the chemical chain.
- The odor trap of in any one of claims 1 to 17, wherein the low-density sealant (20) has a specific gravity not exceeding 0.9.
- A system for draining wastewater, comprising:a) an odor trap as defined in any one of claims 1 to 19,b) a draining surface member for directing wastewater into said at least one entry opening (16D) of said trap.
- The system as defined in claim 20, wherein said draining surface member is a wall mounted urinal (140).
- The system as defined in claim 20, wherein said draining surface member is a floor surface.
- The system as defined in claim 20, further including a tool member (180) having projections (183) which are engagable with said at least one entry opening (153) for carrying said trap.
