  • Patent number: 10258185
    Abstract: A system produces a brew from an infusible brew substance using a combination of a mug and a brewer housed within the mug. The mug includes a vessel inside the mug that holds the water used to brew the brew. The vessel has an exit port below its upper rim. A removable stopper closes the vessel. A siphon tube fits through the exit port and extends downward within the vessel to the siphon's suction end. A heating element is immersed in water within the vessel. When electrically energized, the heating element vaporizes the water, which rises to the top and pushes the water downward into the suction end. A mesh filter holds the infusible brew substance or the substance is placed in the bottom of the mug. The mesh filter is located below the siphon sticking out of the exit port. Water flows through the filter into the mug outside the vessel.

  • Patent number: 9125521
    Abstract: A combined multiple beverage brewing apparatus is capable of brewing an individual serving of at least two different beverages such as coffee or tea. The apparatus generally includes a removable brewing basket with separate brewing sections, which are usable in different brewing positions and have separate spouts such that different beverages may be brewed and dispensed without contacting the same spout. The brewing basket is configured to receive a first reusable filter that holds a first brewing material and filters as water passes through and a second reusable filter that holds a second brewing material while hot water contained in the brewing basket steeps the second brewing material. At least one of the brewing sections further includes a valve to hold hot water in the brewing basket until a brewing release mechanism actuates the valve to release the brewed beverage through the dispensing spout.

  • Patent number: 8061263
    Abstract: A sensor head/brew cup with liquid level sensor probes which rotate down into the server to avoid damage to the probes by the server. The sensor head/brew cup moves as a unit, thereby eliminating any gap between the brew cup and the sensor head through which the brewed liquid must pour, thereby preventing spillage. The moveable sensor head/brew allows beverage brewing devices to use servers of various heights. Raising the sensor head/brew cup causes the level sensor probes to rotate upward out of the server, thereby protecting the probes from impact by the server when it is removed from the brewing device. When the level sensor probes are in the upward position they touch electrical contacts completing a self-test circuit confirming electrical continuity through the level sensor probes.

The filtration tank includes a stopper on a bottom, an overflow outlet on a side wall, a filtration mesh having a hot-water duct of silicone rubber, and a lid pivotally connected to a top. When the hot beverage maker is activated to heat, cold water in the water container flows into heating tubes of a heating device via a first connective tube to be heated. Then, hot water flows upwards via a second connective tube into the filtration tank from the bottom of the filtration tank. Thus, the coffee powder/tea leaves inside of the filtration mesh is/are sufficiently infused. The stopper can be pressed upwards to be opened so as to cause the sufficiently infused coffee/tea to drip.

  • Patent number: 6817280
    Abstract: Systems and methods for brewing beverages in accordance with the present invention can improve the flavor of brewed beverages and reduce the vertical space required for a system using suction. One such assembly comprises a brewing chamber adapted to hold a filter having an intake duct for receiving fluid for brewing, and an output duct for expelling a brewed beverage. The brewing chamber is positioned above a pressurizable container, or carafe, having an adjustable standpipe and containing the fluid. The carafe has a heated base, which when heated causes pressure to build up, forcing the fluid up the standpipe, through a check valve, through the intake duct and into the filter. Once substantially all of the fluid has been urged into the brew chamber, the heat is removed, creating a partial vacuum that pulls the brewed beverage back into the carafe. This description is not intended to be a complete description of, or limit the scope of, the invention.

  • Publication number: 20040065209
    Abstract: A device for brewing hot beverages, such as coffee, tea, herbal tea, comprises a lower container for receiving water, an upper container for receiving brewed beverages, and a grounds holder assembly with an injector differential system, into which coffee grounds, tea leaves and herbs are placed. The grounds are subjected to high temperature water and steam, to extract essences and produce a beverage, such as espresso coffee, tea, chamomille and others. The injector differential system has an injector nozzle and a floating piston in the lower portion of the stem. Pressurized hot water and steam from the lower container flow through the injector nozzle, lifting floating piston, at predermined high temperature and pressure, through the holes of lower perforated plate, and then into the grounds for brewing process. The water and steam extract of the grounds pass through inverted funnel and it is collected into the upper cylindrical container.

  • Patent number: 6536331
    Abstract: A device for preparing beverages of the type having a closed compartment, an open compartment, an ascension pipe connecting the two compartments and a location for a filtering device between the ascension pipe and the open compartment. The closed compartment has a bottom that has at least a first and a second area which are at different levels and has a member for separating the two areas. The first area is larger than the second area, is heated, and is at a higher level than the second level and than the end of the ascension pipe. The second, smaller area is unheated and is located near the ascension pipe, but at a level that is below the end of the ascension pipe. In one embodiment the separating member is a rim and in a second embodiment the separating member is an inclined bottom.

  • Patent number: 6393968
    Abstract: With respect to a filter with a fastening device for a coffee-making apparatus of the type where water is brought to a boil in a closed container, whereupon the water is pressed through a riser pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet of the funnel, where the filter is fastened by means of a fastening device which reaches through the riser pipe, the objective is to to provide a filter where the aroma and flavour of the ground coffee is exploited as well as possible and where the filter offers a comparatively large filter surface for the finished coffee, and where the filter can easily be removed from the funnel and cleaned with a view to further coffee-making. Moreover, the filter must be easily replaceable by dismantling the handle and locking clip and fitting these on a new filter.

  • Patent number: RE45476
    Abstract: An improved coffee brewer and brewing method are provided for producing brewed coffee with improved flavor. The coffee brewer includes a brew basket having jet ports connected to a source of heated water and positioned to deliver hot water streams into the brew basket at a location beneath the level of coffee grounds contained therein. These hot water streams turbulently agitate and stir the coffee grounds to produce a substantially fluidized bed of water-borne coffee grounds for improved flavor extraction and enhanced aroma. This fluidized bed is directed against one or more mesh filter elements forming a wall portion of the brew basket for outward passage of the thus-brewed coffee which is then directed into an underlying carafe or the like. In one preferred form, a portion of the brew basket may incorporate a window to permit visual observation of the fluidized bed therein.
