| Full Text | TECHNICAL FIELD The present invention relates to an electronic air cleaner of the land that includes an electron generator that has a pointed head, a collector element, and an electric circuit mcluded in the electronic generator for generating a negative potential on the pointed head and a positive potential on the collector element. DESCRIPTION OF THE BACKGROUND ART An air cleaner of the aforesaid land is apparent, for instance, from Swedish Patent Specification 512 282. In the case of the air cleaner illustrated in this prior publication, the pointed head is disposed so as to point out towards the centre of tiie space in which air shall be cleaned. Moreover, the collector element is comprised of a plate which is positioned so that the pomted head will be directed away from the plate, wliich has a surface area of at least 150 cm2 and a convex shape as seen from the pointed head. Although this air cleaner has been found to fulfil high demands on the cleanmg of ah" m a space in practice, customers have found it somewhat difficult to position the cleaner m rooms of different kinds and configurations as a result of its design. One object of the present invention is to eliminate this drawback. SUMMARY OF THE INVENTION According to the present invention, the pomted head of an air cleaner of the aforedescribed land is mounted on the free end of a cylinder comprised of electrically non-conducthig material, wherein said cyhnder mcludes the electric circuit and the collector element is mcluded m its remaining end, said element being cylindrical in shape and comprised of electrically conductive material. BRIEF DESCRIPTIOlN OF THE DEAWING The mvention will now be described in more detail with reference to the accompanying drawing, winch iliustes examples of embodiments according to the invention, wherein Fig. 1 illustrates an embodiment for suspension from a ceiling; Fig. 2 illustrates an embodiment for placement on a table or floor; and Fig. 3 is a view from above of an alternative embodiment of a collector included in an inventive air cleaner. DESCRIPTION OF A PEEFERRED EMBODIMENT The air cleaner illustrated in Fig. 1 includes an electron generator 12-13 that has a pomted head 12, a collector element 14, and an electric circuit 14 included m the electron generator 12-13 for generating a negative potential on the pointed head 12, via a short conductor, and a positive potential on the collector element 14, via a conductor 18. The pointed head 12, which is comprised of corona points (carbon fibre bristles), (alternatively special steel needles), is mounted on the free end 111 of a cylinder 11 comprised of an insulating material, e.g. ABS plastic. The cylinder 11 includes said elechic circuit 13 at one end thereof whereas the other end 112 extends fully or partially through the collector element 14, which is cylindrical and open both at its top and bottom and comprised of electrically conductive material, e.g. aluminium. In tire illustrated embodimenl, the collector element 14 has an all-round and double-sided collector fimction (inwards and outwards). The cylinder 11 is held centred in the collector element 14 by means of spacers on the inner wall of said collector element. (By cylindrical is not necessaril}' meant a circular-cylinder, but a shape that occurs when a straight generatrix is displaced parallel along a closed path). The air cleaner can be hung by a suspension device 15 from a ceiling 16 for example, alternatively with a line fastened in the cylinder 112. The shortest distance to the ceiling 16 and to a wall 17 should be at least 20 cm. The distance between the collector element ] 4 and the pointed head 12 will preferably be at least 12 cm and at most 300 cm. The air cleaner may be powered from the mains (220 volts} via a ceiling-mounted electric fitting 161 and conductor 191 leading to an adapter (transformer) 19, (alternatively fastened to the ceiling or to a fixed mains connection in the wall), which converts the mains voltage to a low-voltage DC voltage (12 volts). This is delivered via a conductor 192 to tiie electron generator 12-13, whic produces an extremely high DC voltage of very low current about 5 pA. The air cleaner illustrated in Fig. 2 is principly of the same construction as that shown in Fig. 1, comprising cylinder 11, pointed head 12 and collector element 14. However, the components are placed in reverse in this case, so tirat tlie pointed head 12 faces upwards. Furthermore, the air cleaner includes a foot 21-22, which can be placed freely on a floor (or a table). The foot 21-22 consists of an outwardly extended plastic part 21 of the Cylinder 11 and an iron foot plate 22 (alternatively a foot plate comprised of acryhc resin) fastened to the lower end of the part: 21. The alternative embodiment of the collector 14 shown from above in Fig. 3 includes a number of mutually identical bulges 341, 342, ... 34n around the cylinder 11. These bulges have softly or gently rounded transitions so as to avoid tire point effect. The described inventive air cleaner differs from other, conventional air cleaners by vdrtue of the following properties, among other things: • as an electronic air cleaner/ioniser, does not create static fields; • functions in the absence of movable parts (e.g. fans/blowers); • also collects ultrafine panicles (smaller than 0,1 mµ)/?/ in the absence of expensive filters; and is • energy-lean, silent and draught-free. WE CLAIM: 1. An air cleaner having an electron generator (12-13) that has a pointed head (12), a collector element (14) and an electric circuit (13) has in the electron generator (12-13) for generating a negative potential on the pointed head (12) and a positive potential on the collector element (14), characterized in that the pointed head (12) is mounted at the free end (111) of a cylinder (11) comprised of electrically non-conductive (insulating) material; and in that the cylinder(ll) has the electric circuit (13) at one end whereas its remiaining end (112) passes into the collector element (14), which is cylindrical and comprised of electrically conductive material. |
