A device for preparing beverages of the type having a closed compartment (c2), an open compartment (c1), an ascension pipe (23) connecting the compartments, and a filtering device (f1) between the ascension pipe (23) and the open compartment (c1), has some disadvantages in that an external heating s
A device for preparing beverages of the type having a closed compartment (c2), an open compartment (c1), an ascension pipe (23) connecting the compartments, and a filtering device (f1) between the ascension pipe (23) and the open compartment (c1), 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 (c2) has at least two levels (H1, H4), one level of diminished elevation (H4) in a relatively small area around the lower orifice of the ascension pipe (23), the level (H3) of which is at least below the other elevated level (H1) of a relatively large area, the large area being equipped with electrical heating members (he1, he2) 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 (25) for holding a residual of liquid.

[ What is claimed is:] [1.] A device for preparing beverages of the type having a closed compartment, an open compartment, an ascension pipe connecting the compartments and having a lower orifice, and a filtering device between the ascension pipe and the open compartment,whereby said closed compartment includes a bottom, said bottom comprises:a large area having a bottom portion which defines a first level, anda small area smaller than said large area and having a bottom portion which defines a second level, said small area being around the lower orifice of the ascension pipe, said second level being at least below said first level of said large area, and said ascension pipe lower orifice defines a third level, said third level being below said first level,said closed compartment further includes a rim surrounding said large area and defining a reservoir for holding a residual of liquid,said large area further comprising at least a first and a second electrical heater capable of providing a differentiated heating supply to said closed compartment, said at least first and second electrical heater each being controlled by corresponding ones of a switch connected to said at least first and second electrical heater and at least one temperature sensor that controls said switch, wherein said temperature sensor is functionally connected to said switch and said switch is electronically operated; andwherein said ascension pipe is arranged eccentrically in relation to said large area.
