Abstract
A dehumidifying device for a housing, in particular an electronics housing of an electromotor with a dehumidifying chamber includes a wall inside of which a hygroscopic material is received which is designed to bind air moisture from the dehumidifying chamber. The wall of the dehumidifying chamber includes at least one inner membrane permeable to vapor which can be brought into an active connection with an inner receiving space of the housing and an outer membrane which can be brought into an active connection with the outside environment of the housing. The at least one inner membrane and the outer membrane are permeable to vapor at least in a direction in which a transport of air moisture out of the inner receiving space of the housing through the dehumidifying chamber into an outside environment can be ensured.
