VACUUM CLEANER COMPRISING A SIMPLE SIGNAL TRANSMISSION DEVICE ARRANGED BETWEEN THE HANDLE AND/OR ATTACHMENT AND THE BASE PART

摘要

The invention relates to a vacuum cleaner (1) comprising a base part (2) provided with an electric motor, and a handle (6) that can be inserted into the base part and has an operating grip (7) and/or an attachment (9) with an adjusting unit for controlling the power of the electric motor. A signal required to control the power of the electric motor is conducted from the handle (6) and/or attachment (9) to the base appliance (2), a signal receiver being arranged in the base appliance. The aim of the invention is to improve one such vacuum cleaner, especially in terms of the signal transmission between the base part and a handle that can be inserted into the base part and/or an attachment (9), with as simple a structure as possible. To this end, a light source (10) is arranged in the base part (2) as a signal emitter, the signal is generated by the influence of a light wave emitted by the base part (2), and the signal receiver is a light wave sensor (12).
