Abstract: A beverage dispenser, in which a filter is arranged between the lower end of a brewing chamber and the upper end of a fluid receptacle, and a beverage brewed by supplying a raw material and water to the chamber and filtered by the filter is received in the fluid receptacle, and is thereafter delivered to a cup along a beverage path. The beverage dispenser includes a pump arranged partway along the beverage path, and that reduces a pressure in the fluid receptacle to draw the beverage from the chamber, and delivers it to the cup. A predetermined quantity of the raw material and a first quantity of water are supplied to the chamber, and thereafter, during the delivering of beverage, a second quantity of water is supplied to the chamber, so that without interruption, the beverage is delivered to and served in the cup C.

Abstract: A beverage dispenser, in which a filter is arranged between the lower end of a brewing chamber and an upper end of a fluid receptacle. A beverage brewed by supplying a raw material and water to the chamber is forced to drip into the fluid receptacle through the filter F, and delivered to a cup along a beverage path. The beverage dispenser includes: a pressure difference generator for generating a pressure difference between the chamber and the fluid receptacle to force the beverage to drip into the fluid receptacle, and to deliver the beverage to the cup; a pressure sensor for measuring the pressures in the fluid receptacle or in the chamber; and a controller that sequentially determines an interval average for pressure measured by the pressure sensor, and halts, based on results of the interval averages, a drip-brewing and delivering operation for the beverage.
