Definitions
- the invention relates to an electrostatic dust collector comprising a first and a second electrode and a voltage source for applying a voltage between the two electrodes.
- Such an electrostatic dust collector is known from US 2004/0163667 A1.
- the previously known Staubflinder is designed as a floor cleaning device and has a grid-shaped mat, wherein the two electrodes are components of the mat.
- the mat may for example be covered by a cleaning cloth.
- the voltage source is a battery, for example, which is arranged in the handle, wherein the output voltage is converted into a high voltage.
- the area between the electrodes is electrically charged, and the dust to be picked up has a polarity opposite to that of the electrodes and is thereby attracted.
- a charging station for the dust collector provided that the voltage source comprises a battery instead of a battery.
- the previously known Staubflinder have motion detectors to the
- the previously known dust catcher has the disadvantage that the highest field line density of the electric field and thus the greatest polarization effect on the space between the two electrodes is limited by the arrangement of the two electrodes in the grid-shaped mat. Due to the flat arrangement of the two electrodes, no appreciable force occurs on particles outside the electrodes. The particles must first pass into the space between the electrodes and then be polarized to a sufficient extent and then attracted by an electrode. Such electrode configurations and geometries are incapable of attracting dust particles over a distance of several millimeters or even centimeters from electrostatic forces. Covering the electrodes with a textile even completely prevents the possibility for the particles to reach the area of greatest electric field strength between the electrodes and further reduces the performance of the previously known device.
- the invention is based on the object to avoid the disadvantages mentioned above, wherein the dust collector despite the simplest electrode geometry should have a good effectiveness and handling during the intended use. In addition, the dust collector should be easy and inexpensive to produce.
- an electrostatic dust collector in which the first electrode is formed as a dust-collecting device and the second electrode is grounded.
- the second electrode can either be directly via an electrically conductive ground contact (eg for floor cleaning equipment) or be grounded on the user and an electrically conductive handle (eg for dust-catching handsets).
- an electrically conductive ground contact eg for floor cleaning equipment
- an electrically conductive handle eg for dust-catching handsets.
- the dust collector according to the invention is thus particularly well suited for dry removal of dust on household surfaces. Efficiency can be increased by selecting suitable electrode materials and suitable electrode geometries to optimize the electric field of the dust-exposed electrodes.
- the second electrode is preferably designed as a handle.
- the grounding of the counterelectrode over the user by a handle conductively connected to the electrode further has the advantage that the user, regardless of the operating conditions, is at ground potential and thus does not encounter any electrostatic discharge ("no electric shock") when in contact with the environment ,
- the power source can be housed in the embodiment as a floor cleaning device in the electrode holding frame, be arranged in handheld devices in the handle.
- a handle limits a sufficiently large space to accommodate the voltage source.
- the handling of such a dust collector that is particularly good because its focus is close to the body of the user and unwanted leverage, such as when using a very top-heavy cleaning device, avoided.
- the voltage source by their arrangement in the handle well against the outside Protected influences.
- Such a dust collector has a good durability with good reliability.
- the voltage source includes a battery with an output voltage, wherein as a battery in general, a rechargeable battery can be considered.
- the voltage source comprises a charging circuit with voltage divider and bridge rectifier for converting the output voltage into a high-frequency high voltage, wherein the high-frequency high voltage is converted by a rectifier into a static high voltage and applied to a capacitor with preferably small capacitance of particularly preferably 1 nF.
- the capacitor may have a capacity of 0.001 to 100 nF, preferably 0.05 to 10 nF.
- the output voltage can be 1 to 10 V, preferably 1.5 to 3 V, the static high voltage 0.5 to 10 kV.
- Such a low output voltage can be conveniently achieved by standard batteries / rechargeable batteries, which are available at low cost practically everywhere. This is a significant advantage, especially in the field of low-priced consumer goods.
- the static high voltage can be adjustable stepwise or continuously.
- the attraction force exerted by the electrodes on the dust to be absorbed depends on the magnitude of the high voltage, the magnitude of the high voltage being limited by the dielectric strength of the air.
- an adjustable high voltage especially if it is infinitely adjustable, is advantageous.
- the dust collector is independent of location and freely movable used.
- the voltage source can be switched on or off by a charging switch.
- the handle may also include a discharge switch for discharging the voltage between the electrodes.
- the charging switch and the discharging switch can be combined in a combination switch.
- the electrodes may consist of conventional, suitable materials, for example of metallic or polymeric materials.
- the first electrode exposed to the dust may be at least partially covered by a duster. More preferably, the first electrode is enclosed by a bag-shaped duster. It is advantageous that the recording of the dust can be done not only by the potential difference and the resulting attractive force of the electrodes on the dust, but also by direct contact of the dust through the duster. The cleaning performance is improved in particular when the dust on the surfaces to be cleaned not only flies loose but adheres more strongly.
- Particularly good performance properties have a duster when it is at least partially made of microfibres.
- the dust to be picked up can be absorbed in different ways by the dust collector.
- the electrodes may be coated with a smooth, electrically non-conductive material so that the dust is fixed to the material by the electrostatic charge. The dust is thereby without touching the dust from the surfaces to be cleaned by the device over a distance of attracted several centimeters. The attraction happens through influence and / or polarization.
- Influence in this context means a charge transfer in a conductor (e.g., in a conductive dust particle) through an external electric field.
- polarization in this context means that the application of an external electric field (here the electrode) produces a charge shift in a non-conductive material (here the dust particles). This creates a temporary dipole in the particle on which a force acts in the electric field.
- an external electric field here the electrode
- a non-conductive material here the dust particles
- house dust consists of a large proportion of electrically poorly conductive textile fibers, it has to do here mainly with the phenomenon of polarization, the limits of influence, influenced by the ambient conditions such as moisture, are fluid.
- the electrodes can also be coated with a more or less strongly structured, electrically non-conductive textile, such as a nonwoven fabric, a woven fabric, a knitted fabric or fibers, wherein the textile mechanically holds the dust in addition to the electrostatic effect by its porous surface structure ,
- the dust can either be taken up without direct contact of the textile with the surfaces to be cleaned by electrostatic attraction or by a direct contact of the textile with the surfaces to be cleaned, that is by a mechanical recording.
- the electrostatic effect is enhanced by the mechanical effect, which is particularly advantageous for firmly adhering, already aged dust.
- the electrode may be coated with a smooth, non-conductive plastic material such as a plastic film on which the dust particles are deposited. Such a film allows subsequent removal of the dust by easy stripping, or after discharge of the electrode by simply tapping.
- Figures 1 to 3 a first embodiment, wherein in Figure 1 a
- Figure 4 shows a second embodiment, which differs from the first embodiment of Figures 1 to 3 by the combination switch.
- FIG. 1 to 4 two embodiments of an electrostatic dust collector are shown, each of which consists essentially of the handle 4 and a dust collecting device which is attached to the handle 4.
- the dust-collecting device is formed by the first electrode 1, which is completely enclosed in the embodiment shown here by a bag-shaped duster 8.
- the duster 8 may be wholly or partially made of microfibers.
- the handle 4 is formed by the second electrode 2, wherein within the handle 4, the voltage source 3 is arranged and enclosed by the handle 4 protective.
- voltage source 3 is understood as meaning a battery or a rechargeable battery, with an output voltage and a circuit with voltage divider and bridge rectifier for converting the Output voltage in a high-frequency high voltage, wherein the high-frequency high voltage is converted by a rectifier into a static high voltage and applied to a capacitor.
- the output voltage is 1, 5 V
- the static high voltage is about 5 kV.
- the handle 4 is conductively connected to the electrode 2.
- the handle 4 is grounded.
- the second electrode 2 is grounded by the user so that there is a potential difference between the two electrodes 1 and 2 and dust is attracted to the first electrode 1 by the electrostatic dust collector.
- the handle 4 comprises in Figures 1 to 3, a charging switch 5 and a discharge switch 6, in Figure 4 is a combination switch 7, in the charging and 5 discharge 6 are summarized.
- the user picks up the electrostatic dust collector, he presses for charging an electric charge between the electrodes 1, 2, the charging switch or the combination switch 7 and thus the charging switch 5.
- the charge remains as long as the charging switch 5 / combination switch 7 is pressed ,
- the dust-laden dust collector can be stored in a cleaning station, for example. Subsequently, the discharge switch 6 is actuated or the combination switch 7 and thus the discharge switch 6.
- the pressing can be done either by the user or automatically by placing the dust collector in the
