  • Publication number: 20040028572
    Abstract: A deodorizing/odor removal and disinfection device designed to function in conjunction with a waste receptacle such as a garbage can. The device is equipped with an ozone/ion generator that generates an ozone/ion laden air stream and introduces the air stream into the interior of the waste receptacle without unduly interfering with the operation or seating of the lid of the receptacle. A securing mechanism such as a hook secures the deodorizing device to the exterior of the waste receptacle by engaging with the upper edge or lip of the receptacle, and preferably uses a tube to transmit the ozone laden air stream into the malodorous environment.

  • Patent number: 6571421
    Abstract: The vacuum cleaner and steamer apparatus of the present invention has a fluid assembly for generating and delivering true steam to a surface to be cleaned and a vacuum assembly for drawing deposited steam and other matter from the surface. The apparatus also includes a cleaning fluid reservoir for holding cleaning fluid and a waste reservoir for holding vacuumed matter. Preferably, both reservoirs are removable. Highly preferred embodiments have a housing 20 within which the cleaning fluid and waste reservoirs are received and retained. The fluid assembly preferably includes the cleaning fluid reservoir, a fluid pump for pumping cleaning fluid therefrom, a heater within which the cleaning fluid is turned into steam, and a sprayer head for spraying the steam upon the surface to be cleaned. The vacuum assembly preferably includes a vacuum fan driven by an electric motor, a vacuum head through which matter is drawn, and the waste reservoir.

  • Patent number: 6464760
    Abstract: The invention relates to a portable air sterilization and filtration apparatus for removing contaminants from the ambient atmosphere, having a housing with an inlet opening and an outlet opening, filter media and ultraviolet light source, and a motorized fan for maintaining a flow of air through the housing from the inlet opening to the outlet opening. The invention also includes easy access to the filter medium and to the ultraviolet light sources for periodic replacement or cleaning, and integrates a safety lock feature whereby the removal of the filter or the removal of an ultraviolet light source would open the power circuit to the ultraviolet light source, preventing accidental irradiation of the user. The ultraviolet light sources also activate an indicator light viewable by the user when the ultraviolet light sources are energized.

  • Patent number: 6443334
    Abstract: The water dispenser of the present invention preferably has a draw tube mechanism for extending and retracting a draw tube with respect to a water bottle, a water pump for pumping water therefrom through the draw tube, and a dispensing outlet through which water is dispensed. The draw tube mechanism is preferably a rack and pinion set to which the draw tube is connected for moving the draw tube with respect to the water bottle. By preferably employing a substantially rigid draw tube (as opposed to conventional flexible draw tubes), the draw tube is consistently positioned to draw water from the bottom of the water bottle, thereby drawing all water from the water bottle and reducing waste. Some preferred embodiments provide for partial or full automation of the draw tube mechanism, such as by using one or more sensors to detect water bottle position, dispenser door closure, and the like.

  • Patent number: 6363837
    Abstract: A juice extractor module includes a cover and a juice extractor fluted dome and pulp filter which filters the extracted juice. A second module is formed by a pitcher. The juice flows into the pitcher through the pulp filter of the first module. A paddle depends from a third module and is driven by a motor and gears simultaneously with the extractor, for mixing the extracted juice and other ingredients such as water, sweeteners, etc. The third module contains the motor, drive gears and switch in substantial fluid isolation from the first and second compartments, for driving the paddle and the juice extractor. Different extractors may be attached for different size fruits. A lid may be attached over the pitcher for juice/beverage storage.

  • Patent number: 6279458
    Abstract: An automatic, household drip-type coffee making machine with a main housing for receiving and holding a carafe or decanter, and having an method and apparatus for rapidly heating water to form an infused beverage such as coffee. The speed brewing system has an automatic water level sensing system with a float box, a lever and a micro-switch, which detects the level of water in the water tank and when the water reaches a pre-selected level, activates a water heater located within a water bladder, heating the water bladder to a temperature sufficient to vaporize the water passing into the water bladder. The water vapor condenses along a water outlet tube while still retaining sufficient heat to brew an infused beverage. The heated water (condensed water vapor) reaches a shower nozzle plate and is dispensed through the shower nozzle plate into a filter basket which contains a filter and material for making an infused beverage such as regular or decaffeinated coffee.
