A laundry dryer includes a drying chamber, a process air channel having a supply air opening for drawing in process air, an exhaust air opening for expelling process air, an exhaust air channel through which process air is conducted to the exhaust air opening, and a nebulizer that distributes condensate in process air. The dryer further includes a fan in the process air channel for driving process air through the drying chamber, and a heat exchanger that extracts heat from process air flowing out from the drying chamber, supplies heat to process air flowing into the drying chamber, and separates the condensate from the process air for the nebulizer.

1. A laundry dryer comprising: a drying chamber;a process air channel with a supply air opening for drawing in process air,an exhaust air opening for expelling process air,an exhaust air channel through which process air is conducted from the drying chamber to the exhaust air opening, anda nebulizer that distributes condensate into the process air in the exhaust air channel;a fan in the process air channel for driving process air through the drying chamber; anda heat exchanger that extracts heat from process air flowing out from the drying chamber, supplies heat to process air flowing into the drying chamber, and separates the condensate from the process air for routing to the nebulizer. 2. The laundry dryer of claim 1, wherein the nebulizer comprises an ultrasonic nebulizer. 3. The laundry dryer of claim 1, wherein the heat exchanger has a heat sink and a heat source of a heat pump circuit. 4. The laundry dryer of claim 3, wherein the heat pump circuit comprises an inherently closed line system for circulating a cooling agent, the line system includes the heat sink as an evaporator for the cooling agent, a compressor for compressing the evaporated cooling agent, the heat source as a condenser for the compressed cooling agent and a throttle valve for decompressing the condensed cooling agent. 5. The laundry dryer of claim 1, wherein the exhaust air channel stores the condensate. 6. The laundry dryer as claimed in claim 5, wherein the exhaust air channel comprises a collecting vessel for collecting the condensate. 7. The laundry dryer of claim 6, wherein the collecting vessel includes a depression in the exhaust air channel. 8. The laundry dryer of claim 7, wherein the exhaust air channel has a wall region angled to the depression. 9. The laundry dryer of claim 6, wherein the collecting vessel is below the heat exchanger. 10. The laundry dryer of claim 9, wherein the collecting vessel comprises: a first opening on an incoming side relative to the process air flow to the exhaust air channel; anda second opening on an outgoing side relative to the process air flow to the exhaust air channel and that bridges the heat exchanger at least partially in the exhaust air channel. 11. The laundry dryer of claim 6, further comprising a fill level sensor associated with the collecting vessel. 12. The laundry dryer of claim 1, wherein the process air channel is an open channel leading from the supply air opening to the exhaust air opening. 13. The laundry dryer of claim 1, wherein the process air channel has a heater. 14. A method for operating a laundry dryer comprising: driving process air with a fan through a process air channel and a drying chamber;extracting heat from process air flowing from the drying chamber with a heat exchanger;supplying heat to the process air flowing into the drying chamber with the heat exchanger;drawing process air into a supply air opening;expelling process air from an exhaust air opening, the exhaust air opening opening into an environment of the laundry dryer that is external to the laundry dryer;conducting process air exiting from the drying chamber through an exhaust air channel to the exhaust air opening;separating a condensate from the process air with a heat exchanger; andnebulizing the condensate into process air flowing through the exhaust air channel. 15. The method of claim 14, wherein the nebulizing uses ultrasound. 16. The method of claim 14, wherein the extracting heat and the supplying heat is by a heat pump in the heat exchanger. 17. The method of claim 14, wherein the conducting comprises conducting the process air through the exhaust air channel from the drying chamber to the exhaust air opening. 18. The method of claim 17, wherein the nebulizing distributes condensate into the process air in the exhaust air channel. 19. The method of claim 18, wherein the condensate is routed to a nebulizer for the nebulizing. 20. The method of claim 19, wherein the condensate is stored in the exhaust air channel prior to the nebulizing. 21. The laundry dryer of claim 1, wherein the exhaust air opening opens into an environment of the laundry dryer that is external to the laundry dryer.
