Infra red sensor assembly, to monitor dust particle flow through a collection channel to a container in a robot vacuum cleaner, registers the dust particle volume and/or a channel blockage |
摘要 |
<p>The sensor assembly to establish the amount of dust passing through the dust collection channel (SK) to the collection container (SB), especially in a robot vacuum cleaner, has an infra red light emitter (LI) and a receiver (FO) to give a measurement signal as an alternating voltage or pulse voltage to show the volume of dust particles (ST). A direct voltage establishes the operation of the sensor and/or a blockage in the channel.</p> |
