Abstract:
Disclosed herein is a vibration isolation gasket for mounting a food waste disposer to a sink that is at least partially molded onto a portion of the disposer, and preferably to the disposer’s container cover. The vibration isolation gasket preferably includes a rubberized and integrally formed gasket portion, sleeve portion, and over-molded portion. The gasket portion couples to the drain opening and may contain pleats to prevent food ejection from the disposer. The sleeve portion connects the gasket and over-molded portions, bears the weight of the disposer as it hangs from the sink, and acts as the primary structure for reducing vibration-induced noise. The over-molded portion is preferably molded onto the top and bottom of the container cover, which is in turns crimped to the remainder of the disposer housing.
Abstract:
A switching mechanism for a food waste disposer is provided having a plastic one-piece housing that engages an external surface of the food waste disposer by snapping thereto. The switching mechanism also contains a switch capable of enabling operation of the food waste disposer in response to an interlock device positioned within the drain opening. Also provided is a method for converting a continuous feed waste disposer into a batch feed waste disposer. The switching mechanism includes a plug having a male end and a female end that can receive the electrical plug from the continuous feed waste disposer
Abstract:
Connector assemblies for attaching a waste line to a waste disposer are disclosed. In one embodiment, the connector assembly includes a male member (120) and a female member (110). The male member (120) is coupled to the waste disposer and has one or more anchors or tabs (128). The female member (110) is coupled to the waste line (102). The female member has one or more locking members (114) adapted to lock the female member (110) to the one or more anchors (128) of the male member (120). In another embodiment, the connector assembly includes a mounting flange, a connector flange, and a locking member. The mounting flange is coupled to the disposer and has a locking portion and an anchor portion. The connector flange is coupled to the waste line and has a first portion. The anchor portion of the mounting flange holds the first portion of the connector flange adjacent the mounting flange. The locking member is attached to the locking portion and holds a second portion of the connector flange adjacent the mounting flange.
Abstract:
A back-pressure responsive, self-reversing, control valve (14) is coupled to a water powered waste disposal unit (10). The control valve includes first and second bi-directional valves (120, 124) which operate cooperatively to direct fluid from an inlet (94) to a respective first and second opening (98, 100), and facilitate drainage of fluid from one of the respective first and second openings to an outlet (104, 108). A back-pressure responsive actuator (150) is operatively coupled to the first and second valves to operate the first and second valves cooperatively in response to back-pressure at the first and second openings. A hysteretic mechanism (180) can be used to operate the first and second valves rapidly between the first and second positions upon a predetermined amount of back-pressure at either the first or second openings.
Abstract:
A food waste disposer includes a food conveying section, a grinding mechanism, and a brushless permanent magnet motor operably connected to the grinding mechanism. A discharge device is configured so as to reduce the overall height of the food waste disposer.
Abstract:
The present invention relates to a sink mounted food waste disposer. The present invention comprises of a inlet section including a first draining pipe and a second draining pipe, said second draining pipe having lots of small inlet holes, located along said first draining pipe on the lower center; a first conveying screw inside a screw cover rotated by a first motor; a second motor mounted on a bracket fixed on a plate, moving a first gear by operating a gear box; a compression/grinding section rotated by said first gear, compressing (dehydrating) and grinding food waste conveyed by a first conveying screw; and a drying/disposal section mounted beside said compression/grinding section, drying and disposing the compressed and grinded food waste. With a compact size of the present invention unit, it can be easily mounted in a sink. It can remove odor and leaching water from food waste completely Said disposer also minimize water pollution by purifying 90 % of discharged water. The new food waste disposer enables recycling of food waste to livestock food or compost by removing salt from food waste. The present invention provides a sink mountable food waste disposer with reliable quality and several outstanding features.
Abstract:
A food waste disposer (100) having devices to reduce noise is disclosed. The disposer has a food conveying section (112), a motor section (114), and a grinding section (116). To reduce the emitted noise that may result when food waste impacts the various components of the grinding section, in one embodiment, the present invention uses sound reduction layers (160) attached to the external surfaces of the food conveying section, the motor section, and/or the central grinding section. The sound reduction layers may be made of materials that absorb, block, or dampen the emitted noise. The rotating shredder plate (134) may have a first metallic layer, a second damping layer, and a third metallic layer. The stationary shredder (130) ring may be made of a high-mass material or have a high-mass ring in connection with a stationary shredder ring. These devices may be combined with various disposer inlet baffles.
Abstract:
A baffle (160) for a food waste disposer to reduce noise is disclosed. The baffle (160) has a diaphragm that allows solid and liquid waste to pass through the diaphragm, and accordingly does not substantially affect the normal operation of the disposer. However, because the baffle (160) covers the central opening in the conventional mounting gasket (150) of the prior art, a direct path from the grinding mechanism in the disposer (110) to the sink (120) is blocked, thus muffling the noise coming from the grinding mechanism. Additionally, the disclosed baffles are preferably, but not necessarily, designed so as to create a water dam on their surface by impeding the flow of water from the sink faucet in a way to create a pool of water. The disclosed baffles (160) may be installed in the drain opening (122) of a sink (120) above the conventional mounting gasket, although other embodiments are also disclosed.
Abstract:
A water powered waste disposal apparatus (10) has an adjustable valve (14) with adjustable operating pressure requirements. The disposal apparatus (10) has a plurality of cutters (34) disposed in a passageway (30) for cutting waste. A reciprocating piston (74) is driven by pressurized water in an annular chamber (58). The piston (74) is coupled to at least one rotatable cutter (54). The valve (14) has a reciprocating control piston (110) for selectively diverting the pressurized water into the annular chamber (58) on alternate sides of the drive piston (74). A reciprocating pilot piston (160) selectively conveys the pressurized water to alternate sides of the control piston (110) in response to water pressure in the annular chamber (58). A detent (208) and spring (218) apply an amount of resistance to the pilot piston (160) such that water pressure in the annular chamber (58) must reach a certain threshold pressure to overcome the resistance of the detent (208) and spring (218). An adjustment mechanism (230) has a threaded member (234) engaging the spring (218) to adjust the amount of resistance applied by the detent (208) to the pilot piston (160) as the threaded member is advanced and retracted.
