Problems solved by technology

[0003] Known vacuum cleaners have the disadvantage that the maximum field line density of the electric field is limited to the space between the two electrodes and thus the maximum polarization effect due to the arrangement of the two electrodes in a grid-like pad The space between these two electrodes
The covering of the electrodes with fabric even completely prevents the possibility of particles reaching in the region of maximum field strength between the electrodes and further reduces the effective power of the known device

Embodiment Construction

[0028] exist Figures 1 to 4 Two embodiments of electrostatic cleaners are shown in , each of which is mainly composed of a handle 4 and a dust collection device fixed on the handle 4 . The dust collecting device is formed by a first electrode 1 which, in the exemplary embodiment shown here, is completely surrounded by a bag-shaped dust cloth 8 . The dust cloth can consist entirely or partly of microfibres.

[0029] The handle 4 is formed by the second electrode 2 , wherein a voltage source 3 is arranged inside the handle 4 and is protectively surrounded by the handle 4 . In the present invention, the voltage source 3 is a battery or a rechargeable accumulator with an output voltage, and a circuit with a voltage divider and a bridge rectifier for converting the output voltage into a high-frequency high voltage, wherein the high-frequency high The voltage is converted to a static high voltage by a rectifier and applied to a capacitor. In this embodiment, the output voltage is...

Abstract

The invention relates to electrostatic dust catcher comprising a first (1) and a second electrode (2) and a voltage source (3) for applying an electrical voltage between the two electrodes (1, 2), characterized in that the first electrode (1) is designed as a dust catching device and the second electrode (2) is grounded.

Description

technical field [0001] The invention relates to an electrostatic cleaner comprising first and second electrodes and a voltage source for applying a voltage between the two electrodes. Background technique [0002] One such electrostatic cleaner is disclosed in US2004 / 0163667A1. The known vacuum cleaner is designed as a floor cleaning device and has a grid-shaped pad, the two electrodes being a component part of the pad. The pad can be covered, for example, with a cleaning cloth. The voltage source is eg a battery provided in the handle, where the output voltage is converted to a high voltage. The region between the electrodes is electrically charged, wherein the dust to be collected has an opposite polarity with respect to the electrodes and is thus attracted. Furthermore, charging stations for vacuum cleaners are known if the voltage source includes accumulators instead of batteries. Furthermore, known vacuum cleaners can have motion detectors. [0003] Known vacuum cl...
