Beverage machine with ergonomic water management

摘要

A machine (1) for preparing a beverage has : - a reservoir (3) for containing a liquid (50) that is delimited by a see-through reservoir wall (33) such that a level (51) of this liquid is visible by a user from outside the reservoir; - a circuit for circulating a predetermined volume of said liquid from the reservoir to an outlet (4) for dispensing a beverage containing said liquid upon a user-request; and - a means for alerting a user of an available volume of liquid in the reservoir that is below this predetermined volume. The alerting means comprises a user-visible marking (35, 351, 352) on or adjacent to the see-through reservoir wall (33) at a location corresponding to a minimum level of liquid in the reservoir and visible by a user through the see-through reservoir wall, the minimum level corresponding to a level in the reservoir of this predetermined volume of liquid.
