Ceiling electrode arrangement for electric air conditioning systems

The innovation relates to an electrode arrangement for electric air conditioning ^, especially for motor vehicles one electrode, isolated from ground, attached to the ceiling and connected to the floating pole of a DC voltage source is.

It is known to physically influence the room air by means of electrical fields. This leads to a Change in air ion density and ion balance, which has physiologically beneficial effects on humans will. In particular, symptoms of fatigue caused by climatic and physical conditions can be reduced; one occurs nervous calming and the efficiency of the affected persons is generally improved. These effects have a particularly favorable influence on the ability of a driver to react, which is in the interests of road safety is of great importance.

It is known that the entire remaining space delimitation is used as the counter electrode to use, i.e. the ceiling electrode with one pole of the DC voltage source and the remaining boundary surfaces, In the case of a motor vehicle, for example, the body with the other

Bs is already known, the space of high field strength between Ceiling electrode and room ceiling for electrostatic dedusting to use. However, rtlsfciv to generate sufficiently high field strengths for electrostatic filtering with a lower available direct voltage. aside from that the removal of the separated dirt is not easy.

In all those cases in which there is only little space available in terms of height, e.g. in a motor vehicle, an insulating material is introduced into the quay between the ceiling electrode and the ceiling, e.g. . . '■'.'-- /

The! Inflation is an object, a top electrode assembly to be created en> that allows even at a low height dimension and low Grleichspannung, in addition to air-conditioned electrical teid to achieve Elektrofliterwirkung, learner, it is striving to be able to easily clean these blankets electrode array.

This object is achieved according to the invention in that with of the electrode, a second ground electrode is combined to form a structural unit, in which the two electrodes are arranged at a distance one above the other, connected to one another by an insulator arrangement, but otherwise separated by a layer of air. ^

Using the second electrode creates above The top electrode has an air gap of a precisely defined size in which a very strong surface can develop. Since both Electrodes to form a mechanically stable unit that can be standardized connected, the mutual distance can be very small

hold, which on the one hand leads to a lower installation height, for example 30 mm and less, and on the other hand allows a very considerable field strength to be generated. The distance between the two electrodes can be selected to be so small that field strengths of more than 10,000 V / m are achieved between them despite relatively low voltages. The current for charging the electrodes can, however, be kept so low that they can be touched completely safely. The electrodes can also be removed as a unit and then easily cleaned. Since there is no electrical field between the upper electrode and the ceiling, the contamination that would otherwise occur there is largely avoided. * _ ■

In a preferred embodiment, the insulator assembly consists of one between the electrodes along a Rod-shaped or tubular insulator arranged in the center line. The unit can also be attached to the vehicle ceiling by means of this isolator be attached.

It is advantageous here if both electrodes have a cross section have a V-shape with the legs slightly inclined upwards, what. the electrodes on the one hand increased static strength there and on the other hand it makes the upper one with Ground connected electrode with a certain bias against the ceiling or some intermediate layer, e.g. Car headliner, put on / This creates a horizontal and vertical oscillation of the electrode assembly in spite of a two-point attachment largely avoided, so that there are no noticeable field changes resulting from mechanical vibrations, appear.

The unit can be fitted with the interior mirror screw connection and at the back with the middle of a separately mounted cross bracket get connected. You can then easily assemble and close Remove for cleaning purposes.

The opposing surfaces of the electrodes expediently have a metallic coating or are themselves made of metal. In this way, the highest possible field strengths can be achieved.

The hiring is shown below using one in the drawing illustrated embodiment explained in more detail. Show it:

Fig. 1 is a schematic illustration of the electrode arrangement and

Pig. 2 shows a partial schematic section through a motor vehicle with built-in electrode. - "'

The electrode assembly consists of an upper electrode EM and a lower electrode ES, which is formed by a rod-shaped Isolator SJ connected and spaced from each other being held. Both electrodes have an F-shaped cross-section, the two legs moving slightly from the longitudinal center line;

tilt upwards. The rod-shaped electrode also possesses two mounting holes A and B. ·. .

The lower electrode ES is connected to one pole of a battery V, the upper electrode EM is connected to the other pole of this battery. The latter pole is grounded, i.e. on the vehicle body. As a result, an electric field is created between the lower electrode ES and the body or the related vehicle parts and people as well as a much stronger electric field between the two Electrodes EM and ES.

The installation of such a structural unit under a vehicle roof '"<can be seen in FIG. 2. With the front fastening hole A, the insulator SJ ^{is attached via a bracket:} ν to the fastening device'" provided for the interior mirror.

At the rear end is on the fastening devices for the Handles HG a bracket SB "attached to the litte a Thread t3% t, in which a fastening hole B penetrates Knurled screw MS engages. The cross bracket consists of a steel belt, all that is needed for every type of vehicle to be produced separately; the rest of the electrode assembly can be used for almost all types of vehicles. /

It can be seen from this that the structural unit can be easily retrofitted can be mounted and that it can also be easily removed for cleaning purposes.

A simple and inexpensive capacitor is used as the battery V. Rectifier circuit, - the one with the chopped direct current is fed, the one behind the breaker contact of the ignition system can be taken. A maximum of 10-15 mA is required for this, which only insignificantly loads the "breaker contact". The well-known capacitor-aligning circuit multiplies the chopped voltage of the battery Ba and delivers the required high DC voltage without the use of additional transformers. IJe.tztere are known to generate electromagnetic vortex springs and cause additional costs. In the vehicle. are indeed on everyone, lall electromagnetic Wirbäf.eider by the ignition coil, which is why it should be turned off biological considerations do not multiply yet. The described The voltage source is two to three times as much in one housing Size of a matchbox mountable, which means no additional raises accommodation problems.
