COFFEE MACHINE
A coffee machine has a container for coffee beans, a grinder to which coffee beans can be fed from the container, a filter holder into which ground coffee can be fed from the grinder via a shaft, and a supply device for hot water which can be introduced into the filter holder. In the shaft between the grinder and the filter holder a closing device is provided with a rotatable flap which is movable between an open and a closed position. The flap is rotatable about an axis which extends substantially parallel to a plane of the flap and has a seal arranged on the outer periphery. This allows the shaft to be effectively opened and closed.
1 . A coffee machine comprising:
a) a container configured for holding coffee beans;
b) a grinder configured for receiving coffee beans fed from the container;
c) a filter holder configured for receiving ground coffee from the grinder fed via a shaft;
d) a supply device configured for introducing hot water into the filter holder; and
e) a closing device with a rotatable flap, the flap being disposed in a shaft between the grinder and the filter holder, which flap is movable between an open and a closed position,
wherein the flap is rotatable about an axis substantially parallel to a plane of the flap, and wherein the flap has a seal disposed on an outer periphery of the flap.
2 . The coffee machine according to claim 1 , wherein the plane of the flap corresponds to a sealing plane in the closed position of the flap.
3 . The coffee machine according to claim 1 , wherein the flap in the closed position has an upper side arranged at least partially in the shaft and wherein the upper side of the flap in the open position forms a wall portion facing an inner side of the shaft.
4 . The coffee machine according to claim 1 , wherein the axis of the flap is arranged outside the shaft.
5 . The coffee machine according to claim 1 , wherein the flap is rotatable between the opening and closing positions at an angle between 60° to 120°.
6 . The coffee machine according to claim 1 , wherein the axis extends in a horizontal plane.
7 . The coffee machine according to claim 1 , wherein a downwardly open receiving chamber is formed next to the shaft, into which the flap is insertable in the open position.
8 . The coffee machine according to claim 7 , wherein the flap in the closed position closes the shaft and the downwardly open receiving chamber.
9 . The coffee machine according to claim 1 , wherein the flap, in the closed position, has an underside which, in the open position, faces the outside of the shaft.
10 . The coffee machine according to claim 1 , wherein the shaft below the flap is designed to spread open.
11 . The coffee machine according to claim 1 , wherein a stop is formed on the flap, which stop is configured to be placed against a wall of the shaft.
12 . The coffee machine according to claim 1 , wherein an integrally formed bearing for receiving the axis is formed on the flap.
13 . The coffee machine according to claim 1 , wherein the seal has an outwardly projecting flexible sealing lip.
14 . The coffee machine according to claim 1 , wherein the flap is rotatable by means of a motor which is connected to the axis of the flap by means of a gear.
15 . The coffee machine according to claim 1 , wherein the shaft between the grinder and the filter holder is angular.
