Tørreskab med varmepumpe

The household appliance such as oven, extractor hood, clothes dryer, clothes drying cabinet and/or laundry refresher unit and washing machine or dishwasher comprises a photocatalyst, a light source for activating the photocatalyst, a catalyst section between a starting point and an end point, along which the photocatalyst is arranged, a process air circuit for guiding drying air through a drum, a vapor generator for steaming and/or refreshing clothes, a process water circuit, into which the process water is cyclically pumped, a conveying unit for conveying the liquid, and a filter. The household appliance such as oven, extractor hood, clothes dryer, clothes drying cabinet and/or laundry refresher unit and washing machine or dishwasher comprises a photocatalyst, a light source for activating the photocatalyst, a catalyst section between a starting point and an end point, along which the photocatalyst is arranged, a process air circuit for guiding drying air through a drum, a vapor generator for steaming and/or refreshing clothes, a process water circuit, into which the process water is cyclically pumped, a conveying unit for conveying the liquid, and a filter and/or a tank. The catalyst section is disposed in the process air circuit. The photocatalyst is disposed in the process water circuit. The household appliance is designed to convey a liquid from the starting point to the end point through the catalyst section, to guide along the liquid repeatedly to the photocatalyst in a cycle and to guide along an air mixture to the photocatalyst. A path of the liquid through the catalyst section is longer than a distance between the starting point and the end point, where a part of the catalyst section runs in meander-like, spiral-like or helical-like manner. The oven has a muffle and is designed to guide along the air from the muffle to the photocatalyst and then deliver to the environment, where the air from the muffle is circulated for heating by a heating chamber and is disposed in the heating chamber in the catalyst section. The extractor hood is designed to guide along the sucked air to the photocatalyst. The laundry refresher unit has a chamber for receiving the laundry for washing. A cooling device and a heating device are arranged in the process air circuit, where the catalyst section in the process air circuit is arranged between the heating device and the chamber. A product to be cleaned is admitted into the washing machine or dishwasher with process wat
