Embodiment Construction

[0044] figure 1 A schematic diagram of an embodiment of an air cleaning device 1 according to the invention is shown. It comprises a particle filter 10, a sheet resistance measuring unit 20, a humidity measuring unit 30 and a device 40 for determining the contamination status of the particle filter 10 based on the generated sheet resistance information and the generated humidity information. Optionally, the air cleaning device further includes a fan 50 for generating an air flow through the particle filter 10 .

[0045] The particulate filter 10 may be a fibrous particulate filter and may be made of a hydrophobic fibrous filter material. Sheet resistance measurement unit 20 is configured to measure the electrical sheet resistance of particulate filter 10 (which is typically a measure of the resistance of a film of uniform nominal thickness) and to generate sheet resistance information 21 which indicates or allows Determine the measured electrical sheet resistance. Sheet res...

Abstract

The present invention relates to a device and method for determining the pollution status of a particle filter (10) for an air-cleaning device (1) with increased accuracy at low extra costs. The device comprises a sheet resistance input (43) for obtaining sheet resistance information (21) indicating or allowing to determine an electrical sheet resistance of the particle filter (10); a humidity input (44) for obtaining humidity information (31) indicating the relative humidity of the filter's environment; and a processor (45) for comparing the electrical sheet resistance indicated by or determined from the obtained sheet resistance information (21) with a reference sheet resistance of a clean particle filter at the relative humidity (31) indicated by the obtained humidity information and given at the time of acquisition of said electrical sheet resistance and for generating, based on said comparison, a control signal (41) for control of the air-cleaning device and / or a status information (42) indicating the pollution status of the particle filter (10).

Description

technical field [0001] The invention relates to a device and a method for determining the contamination status of a particle filter in an air cleaning device. Furthermore, the invention relates to an air cleaning device. Background technique [0002] In addition to ventilating with outside air, portable room air cleaners are increasingly being used to at least partially clean indoor air of polluting particles and (odorous) gases. Air purifiers are popular with people living in megacities, where the outdoor air can be heavily polluted. High outdoor air pollution levels make outdoor air unsuitable for indoor air purification by ventilation. [0003] One of the tasks of the air purifier is to efficiently remove particles and gases (VOC, ozone, NO 2 ) and smell. Smoking is a particularly serious source of indoor air pollution. Air purifiers are usually equipped with pleated fibrous particle filters to capture (smoke) particles from the air, and activated carbon (AC) filters...
