PROCESS AND DEVICE FOR CLEANING AND DRYING THE INTERNAL SPACE BETWEEN PANES IN INSULATING WINDOWS

摘要

The invention relates to a device for cleaning the internal surfaces of insulating glass panes with the aid of a wiper unit (10) which can be inserted between the panes. This wiper unit consists at least in part of ferromagnetic material and can thus move between the panes under the action of a moving magnet situated outside the panes. The wiper unit (10) is a hollow body made of flexible material and communicating via a hose (11) with the outside. It can be expanded by pneumatic or hydraulic pressure via the hose (11) until it is in contact with both internal surfaces of the glass panes (15, 16). The invention also relates to a process and device for drying the internal space between the panes involving the supply and removal of air as a carrier medium for water. The intermediate space is incorporated into a closed air circulation system in which inlet and outlet pressures are substantially the same, and condensation occurs with separation of the condensate. In addition, an air-permeable closure device is also provided. This closure device can be inserted into the cleaning aperture of a pane, and is air-permeable but not water-permeable.
