Embodiment Construction

[0021] figure 1 A suction cleaning device 1 is shown, here as a hand-held guided device, which is designed with a base device 8 and a suction nozzle 2 connected to the base device. The suction nozzle 2 is detachably arranged on the base unit 8 in the manner of an add-on unit. The base station device 8 has a handle 9 which is telescopically designed so that the user of the suction cleaning device 1 can adjust the length of the handle 9 to suit his height. Also arranged on the handle 9 is a handle 10 on which the user can guide the suction cleaning device 1 during normal working operation, that is to say move it over the surface to be cleaned. During working operation, the user generally guides the suction cleaning device 1 in opposite directions of movement over the surface to be cleaned. In this case, the user alternately pushes and pulls the suction cleaning device 1 away and back. For example, a switch 11 is arranged on the handle 10 in this case, which is used, for examp...

Abstract

The invention relates to a suction cleaning device (1) having a suction nozzle (2), a suction fan and a suction channel (4) opening into a suction mouth (3), which provides a flow connection from thesuction mouth (3) to the suction fan, wherein the suction channel (4 ) has a sensor (5) for detecting electrically charged particles flowing through the suction channel (4), the sensor (5) being assigned an evaluation device (6) for determining a particle concentration and / or quantity on the basis of the detection result of the sensor (5) is. In order to reliably determine the determined particle concentration and / or amount, it is proposed that the evaluation device (6) is set up to apply a correction value and / or an evaluation method when determining the particle concentration and / orquantity, which environmental parameters influence the detection result, operating parameters and / or device parameters represent.

Description

technical field [0001] The invention relates to a suction cleaning device with a suction nozzle, a suction fan and a suction channel leading into the suction nozzle, the suction channel providing a flow connection from the suction nozzle to the suction fan , wherein the suction channel has a sensor for detecting charged particles flowing through the suction channel, wherein the sensor is equipped with an evaluation device for determining the particle concentration and / or the amount of particles based on the detection results of the sensor . Background technique [0002] Suction cleaning devices of the above-mentioned kind are known in the prior art. [0003] The suction cleaning device has a suction channel which, on the one hand, has a flow connection to a fan and, on the other hand, opens into a suction nozzle. When the fan is in operation, the surface to be cleaned is subjected to a negative pressure via the suction nozzle, so that dust and / or dirt lying on the surface ...
