Problems solved by technology

[0003] A disadvantage of this known coffee maker is that the cut-off time varies from device to device, which makes the determination of the puffing phase or the holding phase very unreliable and inconvenient for the user

Embodiment Construction

[0017] figure 1 Represents a mobile coffee maker. Cold water 4 in the water container 2 is drawn through a flow tube 6 to the outlet opening 8 which opens into a filter holder 10 containing ground coffee. The brewed coffee is received in the coffee maker 12 . During the flow phase or the suction phase, the flow tube 6 is heated by means of the heating element 14 which also keeps the coffee pot 12 warm when all the water 4 has been suctioned off. As long as there is still water in the flow tube 6, heating by means of the heating element 14 will cause the water 4 to be drawn into the outlet opening 8 and cause hot water to drip into the coffee pot 12 through the ground coffee in the filter holder 10 . As soon as the water 4 in the water container 2 is used up, the holding phase starts immediately and the flow tube 6 is no longer cooled, with the result that the temperature of the flow tube 6 starts to rise. This temperature rise is detected by a thermostat 16 thermally coupl...

Abstract

An apparatus for making beverages, such as a coffee machine, has means for measuring the time period during which the heating element is switched off and on by a thermostatic device (16) connected in series with the heating element (14). Calculate the ratio between the off period and the on period. If the off period is smaller than the on period, an indication is given that there are lumpy coffee deposits in the water pipe (6). If the off period is greater than the on period, an indication is given that the coffee has been brewed and the heating element (14) is preferably permanently disconnected.

Description

technical field [0001] The invention relates to a device for making beverages, comprising: a container for holding water, an electric heating element for heating the water, delivery means for delivering the heated water to the outlet opening, a device for switching on and off Automatic thermoregulation of the heating element, and measuring means for measuring the off-period of the heating element. Background technique [0002] Such a device, in particular a coffee maker, is disclosed by European patent application EP0171619. Such a known coffee maker is of the flow type, the water container of which is connected to the outlet opening via a flow tube, said flow tube being heated by a heating element. Cold water from the water container is heated by the heating element within the flow tube and forced to the outlet opening where hot water enters a coffee pot through a filter holder with ground coffee. After the water container has been filled with cold water and the heating e...
