Plumbing fixtures, namely, architectural drain cartridges and related components

Abstract

The inventive subject matter provides apparatus, systems, and methods in which a valve mechanism is incorporated into a drain to reduce or prevent noise or food fragments from emitting out of an operating garbage disposal. The valve mechanism is generally a skirt valve biased to a closed position, disposed within a housing, and inserted into a drain such that food or fluid passes through the valve into a downstream grinding device. Once the food or fluid has passed through the valve, the valve closes.

IPC Classes  ?

• B02C 23/36 - Adding fluid, other than for crushing or disintegrating by fluid energy the crushing or disintegrating zone being submerged in liquid
• E03C 1/266 - Arrangement of disintegrating apparatus in waste pipes or outletsDisintegrating apparatus specially adapted for installation in waste pipes or outlets
• B02C 18/00 - Disintegrating by knives or other cutting or tearing members which chop material into fragmentsMincing machines or similar apparatus using worms or the like

Abstract

A drain insert is described that provides a valve that prevents backflow of objects and materials through the drain inlet and which has an internal wall with a convex curvature. This convex curvature, which can be elliptical, provides improved fluid flow rates relative to straight walled, cylindrical configurations, permitting small diameter drains to utilize the drain insert while meeting IAPMO flow rate requirements.

• E03F 5/042 - Arrangements of means against overflow of water, backing-up from the drain
• F16K 15/14 - Check valves with flexible valve members

Abstract

Sliding skirt valves for waterless urinals and method of controlling fluid flow through the sliding skirt valve are presented. The sliding skirt valve has a valve body, which includes an inlet, an outlet and a sealing surface. The sliding skirt valve also has a central shaft with an upper stop and a lower stop and a barrier interface. Between the upper and the lower stops, a conical barrier is slidingly engaged with the barrier interface. In a normal pressure state, the conical barrier lies against the lower stop of the central shaft. In a back pressure state, the conical barrier moves upwardly to lie against the upper stop of the central shaft and block the vent to upward fluid flow from the downstream of the sliding skirt valve.

• A47K 11/12 - Urinals without flushing
• E03D 13/00 - Urinals

Abstract

A treatment device for a drain is presented to reduce at least one of odor, insect, uric acid, and grease and oil problems. The treatment comprises a dispenser that is configured to couple a stem from a drain extending into a drain pipe. At least a portion of the dispenser is composed of the active agent and thereby dispenses the active agent. The active agent includes at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. Thus, problems associated with drains are substantially reduced using the treatment device.

IPC Classes  ?

• E03F 5/04 - Gullies with or without odour seals or sediment traps
• E03C 1/26 - Object-catching inserts or similar devices for waste pipes or outlets
• A01M 1/20 - Poisoning, narcotising, or burning insects
• A61L 9/00 - Disinfection, sterilisation or deodorisation of air

Abstract

Various embodiments of a device for regulating a fluid flow are described that can include first and second downwardly-sloping valves that are biased in a closed position to prevent odors from escaping the device. The device can also include first and second downwardly-sloping valve seats, and configured such that an end portion of the first valve can be seated beneath the first valve seat and an end portion of the second valve can be seated beneath the second valve seat when the first and second valves are in a closed position, respectively.

Abstract

Various embodiments of a cartridge for regulating a fluid flow are described that include an upper housing, and an insert that is user-removable from the upper housing. The cartridge can include one or more valves that are biased in a closed position to prevent odors from escaping the cartridge. The cartridge can also include a fluid trap that is at least partially disposed within the cartridge or fluidly coupled thereto. An ultraviolet light can be inserted within the cartridge to disinfect a fluid passageway of the cartridge.
