Abstract
A household appliance having a drying apparatus, such as a dishwasher, a washer-drier, a washing machine or the like, is shown according to the invention, wherein a contact zone is provided in a contact chamber for extracting moisture out of the air, which originates from a working chamber of the household appliance, by means of contact between the air and a hygroscopic liquid and wherein a separating element is present for separating hygroscopic liquid out of the air, characterized in that a separating surface is formed downstream of the contact chamber in the direction of flow by the surface of the wall of an air duct.
Claims18
In a household appliance having a drying apparatus, having a primary circuit with a hygroscopic liquid and a secondary circuit, the secondary circuit having a contact chamber with a contract zone for extracting moisture out of air, which originates from a working chamber of the household appliance, and provides contact between the air and the hygroscopic liquid to separate the moisture out of the air, wherein the improvement comprises a separator element with a separating surface disposed outside the contact chamber and downstream from the contact chamber in the direction of flow to separate liquid droplets from air flow from the contact chamber and return the liquid droplets to the contact chamber in the primary circuit.
A household machine with a moisture extractor comprising:
- (a) a primary circuit having a hygroscopic liquid container connected to a pump and a contact chamber with a return line to the hygroscopic liquid container;
- (b) a secondary circuit having a working chamber connected at one end to the contact chamber and connected at the other end to a separator device disposed in the secondary circuit outside the contact chamber and downstream from the contact chamber;
- and
- (c) an air flow drive to move air in the secondary circuit through the working chamber, the contact chamber and the separator device.
