Fully automatic beverage machine for freshly brewed hot beverages

Abstract

A fully automatic beverage machine for preparing freshly brewed hot beverages, having at least one hot-water generator (), a brewing device () to which hot water can be supplied from the hot water generator (), and a water pump () which pumps drinking water from a drinking water supply line () to the hot water generator (). The hot water generator () is a continuous flow heater and a flowmeter () for determining the volume of drinking water pumped by the water pump (). Additionally, the fully automatic beverage machine is equipped with an automatic decalcification system () for automatically decalcifying the continuous flow heater (). The decalcification system has a mixing container () for mixing a descaling solution, a receiving chamber for a storage container () for liquid decalcifier concentrate, and a metering pump () for pumping decalcifier concentrate out of the storage container () into the mixing container () in a metered manner, wherein the descaling solution is mixed from decalcifier agent concentrate and water in the mixing container. The water pump () can be connected to a removal line () of the mixing container () in a switchable manner on the suction side via a first directional valve () in order to pump the descaling solution from the mixing container () to the hot water generator () in the switched valve position of the first directional valve (), and the water pump () can be connected to a water supply line () of the mixing container () in a switchable manner on the pressure side via a second directional valve () in order to pump drinking water to the mixing container () in the switched valve position of the second directional valve ().
