The invention claimed is: 1. A device for producing milk foam, comprising a mixing chamber (13), a milk supply line (11) for supplying milk to the mixing chamber, an air supply line (20) for supplying air to the mixing chamber, and a rinsing medium supply line (21) for supplying rinsing medium to t
The invention claimed is: 1. A device for producing milk foam, comprising a mixing chamber (13), a milk supply line (11) for supplying milk to the mixing chamber, an air supply line (20) for supplying air to the mixing chamber, and a rinsing medium supply line (21) for supplying rinsing medium to the mixing chamber, the air supply line (20) having an end segment (20a) connected to the mixing chamber (13), the end segment being selectively connectable via a first valve (22) to a rinsing medium line (23), and a rinsing line (15) supplied with rinsing medium being connectable to the milk supply line (11) by a connection (14), such that the rinsing medium can be supplied to the mixing chamber at least partially via the milk supply line (11) and at least partially via the air supply line (20), wherein the first valve (22) is arranged at a distance from the mixing chamber (13) and at a higher level than the mixing chamber. 2. The device according to claim 1, wherein the first valve (22) selectively connects at least the end segment (20a) of the air supply line (20) to an air source or to the rinsing medium. 3. The device according to claim 2, wherein the rinsing medium supply line (21) is a water/steam supply line. 4. The device according to claim 1, wherein the first valve (22) is a double valve (22, 24) connected to a common actuating element (25). 5. The device according to claim 1, wherein the milk supply line (11) and at least the end segment (20a) of the air supply line (20) are connectable to the same rinsing medium. 6. The device according to claim 1, wherein the rinsing medium comprises first a liquid and thereafter a gas. 7. The device according to claim 6, wherein the gas comprises a compressed gas. 8. The device according to claim 1, wherein the first valve (22) is connected at least to a time controller for triggering a rinsing process. 9. The device according to claim 1, further comprising a check valve (26) arranged in the end segment (20a) of the air supply line (20) downstream from the first valve (22). 10. The device according to claim 1, wherein the device is part of an automatic coffee machine. 11. A method for rinsing a device for producing milk foam, the device comprising a mixing chamber (13) and supply lines (11, 20, 21) for respectively supplying at least milk, air, and rinsing medium to the mixing chamber, wherein the air supply line (20) has an end segment (20a) connected to the mixing chamber, the end segment being selectively connectable via a valve (22) to a rinsing medium line (23), wherein the valve (22) is arranged at a distance from the mixing chamber (13) and at a higher level that the mixing chamber, and a rinsing line (15) supplied with rinsing medium being connectable to the milk supply line (11) by a connection 14 the method comprising supplying the rinsing medium to the mixing chamber (13) at least partially via the milk supply line (11), and subjecting at least the end segment (20a) to a rinsing operation. 12. The method according to claim 11, wherein the rinsing operation for at least the end segment (20a) begins with liquid and ends with blowing the end segment clear with steam and/or compressed air. 13. The method according to claim 11, further comprising rinsing the milk supply line (11) and the air supply line (20) at least partially simultaneously. 14. The device according to claim 1, wherein the connection (14) is a double-acting check valve in which valve elements are biased against inlets of the milk supply line and the rinsing line.
