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 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. For improved maneuverability and control, the body assembly of the apparatus (including both reservoirs, the fan and motor, and preferably the fluid pump and heater) is preferably connected to a base assembly for movement with respect thereto. Preferably, the base assembly carries the vacuum and sprayer heads and a rotary brush driven by a dedicated electric motor. Highly preferred embodiments permit a user to control the amount of steam produced by the fluid assembly and indicate to the user via a humidity sensor and humidity indicator how dry a surface being vacuumed is.

Vacuum cleaner and steamer apparatus

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. The invention employs a three filter media system to remove contaminants from the air stream generated within the device by the motorized fan, including a sponge filter, a HEPA type filter (high efficiency particulate air filter), which will remove 99.97% of the airborne particles of the size of 0.3 microns or larger, and an activated charcoal filter. The ultraviolet light source is disposed so as to irradiate the downstream side of the activated charcoal filter during operation of the unit to provide germicidal activity to the filter's downstream surface and to the air stream as the air stream emerges from the filter prior to its discharge through the outlet opening to return to the ambient. atmosphere.

Ultraviolet air purifier

The invention relates to an automated drip-type coffee or beverage making machine with an automatic bean grinding apparatus and an automatic cleaning apparatus. The invention also incorporates improvements and features such as a projection or boss within the device which improves the operating efficiency of the bean grinding feature, an improved blade configuration which improves grinding efficiency, including a unique blade arrangement employing a plurality of blades of different lengths, and an improved lid for the coffee or beverage container which acts as an insulator, a moving and sealing cover to prevent ground material from escaping during the grinding process, a water tank insulating compartment, a double-walled grinding basket lid to aid in insulation and spreading of hot liquid, and a damping member for reducing the vibrations associated with motor operation.

Automatic coffee maker with grinder

The invention relates to an automated drip-type coffee or beverage making machine with all automatic bean grinding apparatus and an automatic cleaning apparatus. The invention also incorporates improvements and features such as a projection or boss within the device which improves the operating efficiency of the bean grinding feature, an improved blade configuration which improves grinding efficiency, including a unique blade arrangement employing a plurality of blades of different lengths, and an improved lid for the coffee or beverage container which acts as an insulator, a moving and sealing cover to prevent ground material from escaping during the grinding process, a water tank insulating compartment, a double-walled grinding basket lid to aid in insulation and spreading of hot liquid, and a damping member for reducing the vibrations associated with motor operation.

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.

Juice extractor and beverage mixer apparatus

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. The brewing process commences inside of the filter basket and infused beverage drips into the decanter or carafe, as is common in automatic drip-type coffee making devices. Towards the end of the brewing process, the amount of water remaining in the water tank is gradually reduced, and at a pre-selected level, the float box will return to its original position, which will release a trigger on the micro-switch, causing the electric circuit to open and shut off the power to the device, thus concluding the entire brewing cycle.

Rapid brew automatic coffee maker

The invention relates to an improved automated beverage making machine combining a traditional French Press of the plunger/strainer type with an improved automatic hot water dispensing machine, the dispensing machine having a housing, a water tank and automatic electric water heater. The dispensing machine is adapted to communicate with a French Press plunger/strainer extractor where the extractor also functions as a serving carafe for hot infused beverages such as coffee and tea. The invention also employs improved heating circulation and temperature sensing system which recirculates water until the water has reached a pre-selected desired temperature.

Automatic French Press beverage maker

The invention relates to an automated drip-type coffee or beverage making machine with an automatic bean grinding apparatus and an automatic cleaning apparatus. The invention also incorporates improvements and features such as a projection or boss within the device which improves the operating efficiency of the bean grinding feature, an improved blade configuration which improves grinding efficiency, including a unique blade arrangement employing a plurality of blades of different lengths, and an improved lid for the coffee or beverage container which acts as an insulator, a moving and sealing cover to prevent ground material from escaping during the grinding process, a water tank insulating compartment, a double-walled grinding basket lid to aid in insulation and spreading of hot liquid, and a damping device for reducing the vibrations associated with motor operation.
