coffee machine

The invention relates to a coffee machine with one to one Water heater connected to the water heater for the coffee water to be fed to a filter.

Such apparatuses, known in various embodiments, are provided with a mechanism for switching the flow heater on and off Mistake. So much for these holding mechanisms are set up to let the device »*» work »automatically and depending on the presence of water Training extremely vulnerable so far * They do not function reliably. . ■.

The invention aims to provide a coffee machine with a switching

to create a mechanism that does not have the deficiencies mentioned.

For this purpose, a coffee machine according to the invention is characterized in that that in the flow path for the water to be heated a chamber with a pivotable about a fixed point Float and a stationary mercury switch arranged therein for the water heater is added. Included the float chamber can be placed directly under the water reservoir to be appropriate·

W order to clarify the 3rfindung is described with reference to the drawings, an embodiment of the coffee machine.

It shows in it:

Pig. 1 the coffee machine in a vertical longitudinal section, FIG. 2 the water container in a plan view; 3 and 4 vertical longitudinal sections of the float chamber with two different float positions.

According to the drawing, the coffee machine is provided with a base plate 1 with a warming plate 2 for a filtrate jug 3, which carries a removable filter 4. ·

On the base plate 1, a housing 5 is attached, on which a • Water tank 6 is arranged. The bottom of the water tank 6 is provided with a central column 7 and with an eccentrically located, bulged part, which is a float chamber 8 forms. The float chamber 8 is through a with

To them all the time with that Water tank 6 communicating float chamber 8 is .eine line 12 connected, the lower end of which with a Electrically or partially switchable at your choice Water heater 13 is connected to a through the Pillar 7 of the water tank going pipe is connected to a pivotable horizontal pipe 14, the outlet 15 of which is central Arranged over the filter 4 or pivoted away from this position can be.

In the float chamber 8 there is a float 16 which, through a flexible tube 17, is attached to one of the float chambers is attached and thereby between the bottom of the float chamber 8 and the covering hood 11 covering it is freely movable up and down. The float 16 contains a stationary mercury switch 18 arranged in it, its contact points 19 and 20 via lines 21 and 22 passing through the fastening tube 17 to the water heater 13 and connected to an electrical power source

When the coffee machine is started up, the line 12 and the water heater 13 should «if not already up hard under the ochwimmerkammer 8 are filled with water until to be filled to that level. Is in this position, where the float 16 rests on the bottom of the float chamber 8 and the Water heater I3 is therefore switched off (Pig. 4) a any amount of water poured into the container 6, so is
