1. Apparatus for automatically dissolving instant powder in hot water and comprising flow generation means for generating a flow of the hot water impinging onto said instant powder with a circular component, wherein a vertical frothing chamber is provided which includes a cylindrical interior wall into which opens a nozzle, said nozzle being connected with a hot water pressure duct,said vertical frothing chamber has an inlet opening into which opens an inlet funnel which is symmetrical, at the inside, about a vertical middle axis of the apparatus including the vertical frothing chamber,said vertical frothing chamber has a bottom including an outlet opening,said vertical frothing chamber comprises an upper horizontal cover wall including said inlet opening which is a powder inlet opening,the upper cover wall of the vertical frothing chamber arranged between the vertical frothing chamber and the inlet funnel passes smoothly via the powder inlet opening into the inlet funnel, which is disposed above the vertical frothing chamber,an interior wall of said inlet funnel expands outward in a parabolic shape starting at the powder inlet opening, andthe powder inlet opening and the upper cover wall of the vertical frothing chamber are arranged in a same plane. 2. Apparatus according to claim 1, characterized in that above said inlet funnel a conveying powder conveyor device is disposed. 3. Apparatus according to claim 2, characterized by a worm conveyor is provided as said powder conveyor device. 4. Apparatus according to claim 1, characterized in that a free outflow area of said outlet opening is smaller than a free inflow area of said powder inlet opening. 5. Apparatus according to claim 4, characterized in that the area ratio of the free inflow area to the free outflow area amounts to about 4:1. 6. Apparatus according to claim 1, characterized in that said powder inlet opening is round and that the ratio of an interior diameter of said frothing chamber relative to the diameter of said powder inlet opening amounts to about 3:1. 7. Apparatus according to claim 1, characterized in that said outlet opening passes over into a vertical hollow-cylindrical discharge passage. 8. Apparatus according to claim 7, characterized in that a centering rod extends into a lower end of said discharge path. 9. Apparatus according to claim 1, characterized in that said inlet funnel together with said powder inlet opening of said frothing chamber, said frothing chamber, said outlet opening of said frothing chamber and a discharge passage are arranged about a common middle axis. 10. Apparatus according to claim 1, characterized in that a hot water pressure duct is connected to a continuous flow heater which is fed via a water pump. 11. Apparatus according to claim 2, characterized in that a single drive for each of said conveying powder conveying device and of a water pump is coupled to one another by a coupling means. 12. Apparatus according to claim 1, characterized in that a frothing unit comprising said frothing chamber including said nozzle, a water inlet into said nozzle and a discharge passage including a centering rod is designed as a throw-away part that is exchangeable and connected to a hot water pressure duct. 13. Apparatus according to claim 12, characterized in that said throw-away part is designed as one piece. 14. Apparatus according to claim 1, characterized in that that a closable air passage opens into the hot water pressure duct upstream of a water inlet of said nozzle for frothing up.
