Embodiment Construction

[0029] figure 1 A schematic diagram showing an embodiment of the appliance 1 for drying laundry according to the present invention.

[0030] The appliance 1 has an appliance housing 2 in which an open process air system 3 is arranged, and the open process air system 3 has a drying chamber 4 that contains not shown to be dried Of washing. The process air system 3 has a process air blower 5 which can be activated by means of the control electronics 6 of the appliance 1 to perform a drying process.

[0031] Furthermore, the appliance 1 has a heat pump 7 thermally coupled to the process air system 3, which heat pump 7 is configured as a compressor-heat pump. The heat pump 7 has a liquefier 8, an evaporator 9, a compressor 10, an expansion unit 11, and a refrigerant pipeline 12, thereby forming a refrigerant circuit of the heat pump 7, wherein the liquefier 8 is connected to the process air system 3 The ambient air in the heat pump 7 is heated, the evaporator 9 cools and dehumidifies ...

Abstract

The invention relates to an device (1, 14) for drying laundry, comprising at least one open process air system (3, 15) having at least one drying chamber (4) accommodating laundry to be dried and having at least one heat pump (7) thermally coupled to the process air system (3, 15). The aim of the invention is to reduce the energy content of process air at the outlet of the open process air system(3, 15) and to increase the dehumidification power of the device (1, 14). The device (1, 14) has at least one cooling unit (13) thermally coupled to a refrigerant line (12) between a liquefier (8) andan expansion unit (11) of the heat pump (7) for cooling a refrigerant flowing through the refrigerant line (12).
