Problems solved by technology

[0005] A further problem when realizing this device is that modern household appliances must have increasingly smaller energy consumption so that the liquid separation device cannot cope with large pressure differences or flow resistances
Said pressure difference requires that the gas to be dried be conveyed in a correspondingly pressurized manner, which is again expensive

Embodiment Construction

[0029] figure 1 A first circuit 1 and a second circuit 2 for a dishwasher are shown. The first circuit 1 comprises a hygroscopic liquid, for example a lithium chloride solution. The second circuit 2 provides the air circuit.

[0030] In this case, the first circuit 1 comprises, for example, a container 3 containing a lithium chloride solution 4 . The lithium chloride solution 4 can be drawn off via the line 5 by means of a pump 6 developed as a circulation pump 6 . The solution is heated by the heating means 7 so that moisture can escape and thus escape the extraction means, ie the lithium chloride solution 4 is concentrated. The electrolyte solution 4 finally enters the contact chamber 8 in which the first circuit 1 is connected to the second circuit 2 . Thus, in the contact chamber 8 a hygroscopic liquid such as lithium chloride is brought into contact with the air to be dried.

[0031] The second circuit 2 blows drying air by means of a fan 10 into the work box 11 of t...

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.

Description

technical field [0001] The invention relates to a household appliance with a drying device according to the preamble of claim 1 , such as a dishwasher, washer-dryer, washing machine, etc. Background technique [0002] Domestic appliances of this type are described, for example, in document 102010047058A1 or DE 102011117734A1. [0003] The problem when implementing such a household appliance or drying device is, on the one hand, to provide a large contact surface between the hygroscopic liquid and the air to be dried, and, on the other hand, once the liquid has been extracted from the air and provided to the storage container, where the hygroscopic liquid can be collected again. [0004] Increasing the surface of the liquid results in smaller and smaller droplets, which can eventually form an aerosol. The smaller the droplets, the more problematic the separation of dried air. [0005] A further problem when implementing such devices is that modern household appliances must...
