Abstract

An appliance for making coffee, tea and the like comprises an automatic adjustment unit (22) for adjusting the desired quantity ratio between the quantity of water in a water reservoir (2) and the quantity of substance in a filter holder (4). The adjustment unit (22) can adjust the loadable length of a resilient element (50a) in response to the level of the water in the reservoir 2. The resilient element (50a) is pivotally attached to a lever (5) of the filtering system (3). The rotation of the lever (5) is indicated on a strength indicating scale (10, 11, 12).

Description

technical field [0001] The present invention relates to an apparatus for making coffee, tea etc. comprising a housing, a water reservoir and a filtering device. Background technique [0002] A device for making coffee and the like is known from US-A 4055114. In order to obtain good results, the ratio between the amount of water and the substance to be filtered is important. In US-A 4055114 an apparatus is disclosed aimed at brewing coffee etc., wherein the correct amount of substance to be filtered can be determined for any amount of water. In addition, one of the US-A 4055114 devices comprises a housing, a reservoir fixed relative to the housing, a movable element in the form of a float responsive to the water level in the reservoir, a lever and a filtering device. An end of the lever is rotatably connected to the housing at a first pivot. The filter device is rotatably suspended from the lever at the second pivot by means of the carrying cam. The float is connected to ...
