1. A vacuum-operated sanitary device for an aircraft, wherein the vacuum-operated sanitary device comprises a bowl and a flushing device, with the flushing device comprising: a nozzle arrangement with a nozzle inlet of a first cross section;a nozzle outlet of a second cross section; anda nozzle duct of a third cross section;a first delivery device connected to the nozzle inlet;a second delivery device opening into the nozzle duct; andan air nozzle directed onto an interior wall of the bowl;wherein the nozzle outlet is directed onto the interior wall of the bowl;wherein the nozzle duct connects the nozzle inlet to the nozzle outlet;wherein the third cross section is smaller than both the first cross section and the second cross section;wherein the first delivery device is configured to deliver a first flushing medium;wherein the second delivery device is configured to deliver a second flushing medium;wherein the air nozzle comprises a nozzle inlet connected to the first delivery device, such that a first partial quantity of the first flushing medium is delivered to the nozzle arrangement and mixed with the second flushing medium, and a second partial quantity of the first flushing medium is delivered to the air nozzle;wherein the air nozzle is aligned such that a mixture of the first and second flushing medium leaves the nozzle arrangement in closer proximity to the interior wall of the bowl than the second partial quantity. 2. The vacuum-operated sanitary device of claim 1, wherein the flushing device further comprises: a third delivery device opening into the nozzle duct, wherein the third delivery device is configured to deliver a third flushing medium. 3. The vacuum-operated sanitary device of claim 1, wherein at least one of the delivery devices is connected to a reservoir in such a way as to deliver flushing medium present in the reservoir to the nozzle duct. 4. The vacuum-operated sanitary device of claim 1, wherein at least one of the second and third delivery devices is led through the nozzle inlet. 5. The vacuum-operated sanitary device of claim 1, wherein at least one of the second and third delivery devices is led through a sidewall of the nozzle duct. 6. The vacuum-operated sanitary device of claim 1, wherein an outlet opening of at least one of the second and third delivery devices is directed in the direction of a flow direction in the nozzle duct. 7. The vacuum-operated sanitary device of claim 1, wherein an outlet opening of at least one of the second and third delivery devices comprises a spray nozzle. 8. The vacuum-operated sanitary device of claim 2, wherein the first delivery device is configured to deliver air, andat least one of the second and third delivery devices is configured to deliver a liquid. 9. The vacuum-operated sanitary device of claim 1, comprising a plurality of nozzle arrangements, wherein the nozzle arrangements are at least in part aligned along the rim of the bowl towards the interior wall. 10. The vacuum-operated sanitary device of claim 1, wherein at least one of the first, second and third cross sections of a nozzle arrangement is oval. 11. The vacuum-operated sanitary device of claim 1, wherein the nozzle outlet is aligned at a specific angle in relation to the interior wall of the bowl. 12. The vacuum-operated sanitary device of claim 1, wherein the vacuum-operated sanitary device is a vacuum toilet. 13. An aircraft comprising a vacuum-operated sanitary device, the vacuum-operated sanitary device comprising: a bowl and a flushing device, with the flushing device comprising:a nozzle arrangement with a nozzle inlet of a first cross section; a nozzle outlet of a second cross section; and a nozzle duct of a third cross section;a first delivery device connected to the nozzle inlet;a second delivery device opening into the nozzle duct; andan air nozzle directed onto an interior wall of the bowl;wherein the nozzle outlet is directed onto the interior wall of the bowl;wherein the nozzle duct connects the nozzle inlet to the nozzle outlet;wherein the third cross section is smaller than both the first cross section and the second cross section;wherein the first delivery device is configured to deliver a first flushing medium;wherein the second delivery device is configured to deliver a second flushing medium;wherein the air nozzle comprises a nozzle inlet connected to the first delivery device, such that a first partial quantity of the first flushing medium is delivered to the nozzle arrangement and mixed with the second flushing medium, and a second partial quantity of the first flushing medium is delivered to the air nozzle;wherein the air nozzle is aligned such that a mixture of the first and second flushing medium leaves the nozzle arrangement in closer proximity to the interior wall of the bowl than the second partial quantity.
