Abstract (en)
[origin: EP0327936A2] In a mounting for sensors and transmitters providing a means of dust detection in vacuum cleaners, in particular in the form of light- emitting diodes and phototransistors, adjacent to the suction channel of the vacuum cleaner, it is proposed that at least one axial channel be formed in the detection area of the sensor directly adjacent to the sensor from the inside outwards, through which a stream of air is blown on the basis of the negative pressure or excess pressure prevailing in the vicinity of the sensor, continuously blowing clear the sensitive area of the sensor. <IMAGE>
