Abstract: A filtering device for coffee, tea or the like is composed of a jug, a jug opening having thread webs, and an approximately frustoconical filter vessel which includes a circumferential supporting ring having two mutually angularly offset thread groove segments for engaging the thread webs of the jug opening.

Abstract: A method for producing aqueous extracts from ground coffee, by adding coffee to a vessel; adding heated water to the vessel; stirring the resulting coffee-water mixture during a predetermined brewing time to produce an even distribution of coffee in the mixture and to allow expulsion of gas from the mixture; and filtering the coffee-water mixture at the end of the predetermined brewing time to produce a filtered aqueous coffee extract.

Abstract: A beverage maker includes a continuous flow electric heater assembly of tubular construction adapted to be connected to a source of fresh water and is arranged for guiding fresh water therethrough for heating the fresh water to brewing temperatures, and a filtering vessel and pipe arrangement to introduce heated fresh water from the heater assembly to the filtering vessel. The heater assembly comprises at least two tubular continuous flow electric heaters each being bent into a U-shaped configuration. The heaters are arranged in a generally horizontally juxtaposed mutually nested relationship and each has a metal heater tube containing an electric heating element, a metal water pipe extending adjacent the metal heater tube parallel therewith and a heat conducting flat web connecting the heater tube with the water pipe for transferring heat from the heater tube to the water pipe. There is further provided a tubular connector coupling the water pipes of the heater assemblies to one another.

Abstract: A coffee or tea maker includes a freshwater container, a heater for heating water withdrawn from the freshwater container, a filter holder receptacle and a feed pipe extending from the heater and arranged for carrying hot water from the heater; an intermediate container into which the feed pipe opens to introduce hot water thereinto. There is further provided an arrangement for periodically emptying the hot water from the intermediate container into the filter holder receptacle.

Abstract: A coffee or tea maker for delivering hot water to a pot via a filter vessel comprising a fresh water container; an overflow device disposed for introducing the hot water into the filter vessel when the filter vessel is disposed below a portion of the overflow device, the overflow device including an intermediate vessel having first, second and third passages; a riser pipe disposed between the fresh water container and the intermediate vessel and extending through the first passage; a flow heater for heating the water in the riser pipe; a support location for the pot; a siphon extending through the second passage and disposed for periodically emptying the intermediate vessel; and a ventilation pipe extending through the third passage and having first and second ends, wherein the first end of the ventilation pipe is disposed in the intermediate vessel and the second end of the ventilation pipe is disposed outside of the intermediate vessel; and wherein the intermediate vessel is closed on all sides except for t

Abstract: A coffee maker or a tea maker includes a fresh-water container; a flow-through heater arranged for receiving water from the fresh-water container; an overflow arranged for receiving heated water from the flow-through heater; a filter holder accommodating the ground flavor carrier and arranged for receiving the heated water from the overflow; a receptacle arranged for receiving filtrate from the filter holder; and an agitating apparatus disposed in the vicinity of the overflow and the filter holder, for generating a movement of a flavor carrier located in the filter holder.

Abstract: A coffee or tea maker has a freshwater receptacle which is connected with a continuous flow heater by a freshwater intake. Heated water leaves the continuous flow heater through a riser. The freshwater intake and the riser are coupled by a conduit in which cold freshwater and heated water admix and in which a thermostat switch is disposed. The latter controls the energization of the heater as a function of the temperature changes of the water mixture in the conduit. An additional heating means arranged in heat exchange relationship with the thermostat switch maintains the heater in a deenergized state after completion of the brewing process. An adjustable throttle valve may be provided for regulating the admission of fresh water into the conduit.

Abstract: A filter vessel arranged to receive a liquid-permeable filter bag for producing a coffee or tea beverage, the filter vessel having, at its bottom, a filtrate outlet in the form of a siphon which prevents dripping after completion of the filtering process.
