Estimating the term…
In a first embodiment, a beverage brewing machine has a reservoir in which water is heated, which is arranged upstream of a brewing unit and heatable by an electric heating device. At the bottom is an outlet valve which opens only on reaching a given water temperature so that the hot water flows through an outlet pipe downstream of the outlet valve from the reservoir over the upper surface of a product, preferably ground coffee or tea-leaves, contained in a brewing unit, from which it goes to a receptacle as a beverage after extraction of the product. Hot water from the reservoir can also be taken via a pipe along paths other than over the upper surface of the product into the receptacle. The pipe takes a siphon-like path, the vertex of which is far enough above the bottom of the reservoir so that hot water also flows via the pipe to the other path and not only over the upper surface of the product only when a certain level is reached in the reservoir. In a second embodiment, the hot water is conveyed along the other path by a brewing head that has main and secondary chambers.
A beverage brewing machine comprising storing tank structure, brewing structure, supply reservoir structure, an electric heating device coupled to said supply reservoir structure, said supply reservoir structure having a bottom and being adapted to receive water to be heated by said electric heating device, outlet valve structure coupled to said supply reservoir structure for controlling flow of brewing water out of said supply reservoir structure onto the upper surface of a product, preferably ground coffee or tea leaves, contained in said brewing structure, from which, after extraction of the product, the so prepared brewed beverage finally discharges into said storing tank structure, siphon-like conduit structure coupled to said supply reservoir structure through which brewing water can propagate also along a path in said brewing structure out of said supply reservoir structure into said storing tank structure, other than through the upper surface of the product, said siphon-like conduit structure having a vertex disposed above said bottom of said supply reservoir structure, such that, only starting with a defined filling level in said supply reservoir structure, brewing water discharges also through said siphon-like conduit structure and not only through the upper surface of the product in said brewing structure.
A beverage brewing machine comprising supply reservoir structure for receiving cold water, heater structure coupled to said supply reservoir structure for heating cold water flowing out of said supply reservoir structure, distribution structure, brewing structure having an outlet opening, storing tank structure for communication with said outlet opening of said brewing structure, feed pipe structure for conveying brewing water from said heater structure to said distribution structure, said distribution structure containing partition wall structure, said partition wall structure subdividing said distribution structure into a main chamber and a secondary chamber, the entire brewing water flowing from said feed pipe structure into said main chamber, a first outlet opening in said main chamber and a second outlet opening on the opposite side of said partition wall structure from said first outlet opening in said secondary chamber, brewing water, on the one hand, flowing from said distribution structure through said first outlet opening onto the upper surface of a product, preferably tea leaves or ground coffee, contained in said brewing structure, from which, after extraction of the product, the so prepared brewed beverage finally discharges into said storing tank structure, and brewing water, on the other hand, can also flow from said distribution structure through said second outlet opening after having surmounted said partition wall structure, this portion of the brewing water propagating along a path other than through the upper surface of the product into said brewing structure, said distribution structure having closed chamber structure, and vent pipe structure for maintaining said closed chamber structure in constant communication with the atmosphere, said vent pipe structure penetrating the bottom of said closed chamber structure and having a free end which is disposed above the upper edge of said partition wall structure, said pipe vent structure being fitted in said main chamber adjacent said first outlet opening.
A beverage brewing machine comprising supply reservoir structure for receiving cold water, heater structure coupled to said supply reservoir structure for heating cold water flowing out of said supply reservoir structure, distribution structure, brewing structure having an outlet opening, storing tank structure for communication with said outlet opening of said brewing structure, feed pipe structure for conveying brewing water from said heater structure to said distribution structure, said distribution structure containing partition wall structure, said partition wall structure subdividing said distribution structure into a main chamber and a secondary chamber, the entire brewing water flowing from said feed pipe structure into said main chamber, a first outlet opening in said main chamber and a second outlet opening on the opposite side of said partition wall structure from said first outlet opening in said secondary chamber, brewing water, on the one hand, flowing from said distribution structure through said first outlet opening onto the upper surface of a product, preferably tea leaves or ground coffee, contained in said brewing structure, from which, after extraction of the product, the so prepared brewed beverage finally discharges into said storing tank structure, and brewing water, on the other hand, can also flow from said distribution structure through said second outlet opening after having surmounted said partition wall structure, this portion of the brewing water propagating along a path other than through the upper surface of the product into said brewing structure, and valve structure in said distribution structure which permits control of the discharge of brewing water along said other path, said valve structure controlling the cross-sectional size of said second outlet opening and being provided at said second outlet opening.
