Abstract
A device for preparing beverages of the type having a closed compartment (c,), an open compartment (c,), an ascension pipe (,) connecting the compartments, and a filtering device (f,) between the ascension pipe (,) and the open compartment (c,), has some disadvantages in that an external heating source is needed, thereby increasing the risk of fire and burning the operating persons. Further, the infusion time is either fixed, being decided by the distance between the lower orifice of the ascending pipe and the bottom of the closed compartment or left to the user to estimate. In order to avoid these problems the bottom of the closed compartment (c,) has at least two levels (H,, H,), one level of diminished elevation (H,) in a relatively small area around the lower orifice of the ascension pipe (,), the level (H,) of which is at least below the other elevated level (H,) of a relatively large area, the large area being equipped with electrical heating members (he,, he,) controlled by a switch and at least one temperature sensor (v) for controlling the switch, the large area of the bottom being surrounded by a rim (,) for holding a residual of liquid.
