Insect repulsion and/or barrier arrangement and method for repelling insects

Abstract

Disclosed is an insect repulsion and / or barrier arrangement (10) and a method for repelling insects (2) and / or for preventing the passage of insects (2) through a defined opening (12) or surface (9).The insect repulsion and / or barrier arrangement (10) comprises at least one opening (12) located within a wall (8) or a surface which is largely permeable to ambient air. The insect repulsion and / or barrier arrangement (10) is equipped with devices (16) for preventing insects from passing through the opening (12) and / or for repelling insects when approaching the opening (12) and / or the devices (16). The devices (16) have at least two electrodes (18), whereby different electrical potentials are applied to or can be applied to the at least two electrodes (18), which are arranged within and / or onthe edge and / or outside of the opening (12) and in proximity to the opening (12) in a definable distance from each other. The at least two electrodes (18) are arranged in such a way that an electrical field (28) is formed between the at least two electrodes (18), which electrical field (28) is either permanently or cyclically increasing and decreasing or which is present at intervals of time withinterruptions. The permanent electrical field (28) or cyclically increasing and decreasing electrical field (28) or the electrical field (28) which is present at intervals with interruptions, rejectsand / or repels insects approaching the electrical field (28) and / or prevents insects approaching the electrical field (28) from passing through the opening (12).

Description

technical field [0001] The present invention relates to an insect repelling and / or barrier device having the features of independent claim 1 or 2 and a device for repelling insects and / or preventing insects from passing through defined openings or surfaces having the features of method claim 17 method. Background technique [0002] To prevent insects or other vermin from passing through largely air-permeable openings in walls or surfaces, especially insects attracted to human odors, such as flying insects and / or vermin, especially mosquitoes, sand flies, midges , black flies, other flies etc., such openings are usually provided with so-called fly screens, frames or doors, which may be equipped with fine mesh polyester or nylon mesh. The opening can be, for example, a room window or a door that can be opened or closed. Likewise, the openings may also be permanent openings in the wall, such as ventilation shafts or slots, for example, and in many cases fly guards prevent ins...

Problems solved by technology

However, since the grid has low conductivity, the voltage applied to the grid via the electrodes decreases with increasing distance from the electrodes

Another disadvantage of the process and device according to WO 99 / 44418 A1 is that the small mesh size impairs the air exchange in the space covered by the mesh, thus seriously disturbing the air circulation
