Embodiment Construction

[0022] first with the help of figure 1 The description shows a suction cleaning device S consisting of a vacuum cleaner 1 , in particular a household vacuum cleaner designed as a manually guided handle device, and an additional device 10 in the form of a suction nozzle for hard floors. However, the features of the attachment 10 described below can also be taken into account in attachments with rotating brushes for cleaning carpets.

[0023] The vacuum cleaner 1 firstly has a basic unit 2 with an electric motor (not shown) for the extractor. A gas-permeable filter box 3 designed to accommodate the suctioned dust is attached to the base unit 2 . The filter cassette contains filter bags 4 .

[0024] The electric motor integrated in the basic unit 2 is supplied via the cable 5 .

[0025] Furthermore, the basic device 2 has a gooseneck-shaped projection which extends over the region of the filter box 3 . A socket for the handle 6 of the vacuum cleaner 1 is formed in the region ...

Abstract

The vacuum cleaner (S) has a suction port (15) and a suction channel (14), where a capacitive humidity sensor (17) is arranged in the suction channel. The suction channel opens during detection of humidity in a secondary air opening that is spatially attached to the humidity sensor. Monitoring and / or cleaning agents in contact with the humidity sensor proceed during opening movement of the air opening. The air opening is obtained by opening a part of a suction channel wall (21). A locking position of the air opening is secured by magnets (36).

Description

technical field [0001] The invention relates to a motor-operated suction cleaning device with a suction nozzle and a suction channel, wherein a humidity sensor is also arranged in the suction channel. Background technique [0002] Suction cleaning devices of the described type are known, in particular as household vacuum cleaners, in particular also as manually controlled vacuum cleaners, but also in the form of autonomously operating, motor-driven floor cleaning devices, such as suction robots and / or cleaning robots. A moisture sensor arranged in the suction channel detects the liquid sucked in by the suction nozzle of the suction cleaning device. A corresponding signal that is generated when moisture is applied leads to the deactivation of the suction motor generating the suction flow in the known state of the art. However, the motor-driven aspirator coasts after it has been disconnected, continuing to produce a corresponding suction flow albeit continuously falling, so ...
