  • Patent number: 6827004
    Abstract: A drip coffee maker having a horizontal spray of heated water into a brew basket. Much of the effect of gravity is removed and the spread of heated water may be increased. The horizontal spray shower head may be used to expose the top layer of coffee grinds in the brew basket to an equal amount of hot water within a few seconds of brewing start time. By immersing the coffee grinds in hot water at the same level, the coffee grinds are all subjected to the same water pressure. The water then filters down evenly over the coffee grinds in the brew basket. Thus, the coffee grinds within the brew basket are given maximum exposure to the heated water. This exposure allows more coffee to be extracted from fewer grinds, thus conserving coffee and avoiding overcooking of the grinds.

    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.

  • Patent number: 6220147
    Abstract: A method and apparatus for brewing tea is disclosed which utilizes heated water from a boiler of an espresso machine. A porta-filter having a brewing chamber therein is attachable to a group head of the espresso machine such that heated water is directed out of the espresso machine and into the brewing chamber. A drain from the brewing chamber leads to an outlet tube which has a lower end discharging a brewed beverage, such as tea, therefrom. An outlet valve restricts outflow from the brewing chamber to a rate less than inflow of heated water from the boiler so that the heated water is provided with residence time within the brewing chamber. This residence time facilitates infusion of the heated water with soluble flavor particles from a brewable substance such as tea leaves before the heated water is discharged from the brewing chamber in the form of a brewed beverage.
