Definitions

  • the invention relates to an improved electrode of the type used in air conditioning apparatus for generating an electrostatic field, wherein at least one electrode is formed as a plate shaped carrier on which an insulating layer is disposed, an electrically conducting adhesive material being connected to one terminal of a direct current high voltage source and also serving to attach the insulating layer to the carrier.
  • the invention relates to an improved electrode used in air conditioning apparatus generating an electrostatic field, for example in vehicles, as described in US. Pat. No. 3,583,754.
  • Electrodes which use an electrically conductive layer superimposed on an insulated carrier, the conductive layer being protected by an additional insulating layer, e.g. from German Pat. DT-l 630 187.
  • This insulating layer can be either protective, decorative, or may be simply used so that the electrodes can be cleaned more easily.
  • the insulating layer need not change the electrostatic field markedly; it can be very thin or even cover the conductive layer only partially.
  • the invention relates to an air conditioning apparatus of the type where an electrostatic field is established between two electrodes, one electrode being connected to a positive terminal and the other electrode being connected to a negative terminal of a dc. high voltage source.
  • either or both of the electrodes will be composed of a plate shaped carrier with an insulating layer superimposed on that carrier, with a layer of electrically conducting adhesive material serving to attach the insulating layer to the carrier and being itself connected with one terminal of the high voltage source.
  • FIG. 1 is adiagrammatic vertical section through a motor vehicle provided with an electrode construction according to the invention
  • FIG. 2 is an enlarged fragmentary section taken on the line A-A of FIG. 1;
  • FIG. 3 shows a fragmentary bottom plan view of the electrode construction depicted in FIG. 2;
  • FIG. 4 shows a fragmentary perspective view of a self-adhesive foil for use in constructing an electrode according to the invention.
  • the objective of the invention is accomplished by using as the electrically conductive layer of the electrode an electrically conductive adhesive layer, by
  • the electrically conductive adhesive layer then serves two functions, is. adhering to the carrier and also being electrically conductive, it is then merely necessary to attach the insulating layer to the carrier by means of the electrically conductive adhesive layer; this simplifies the manufacturing process for the electrodes. Since the currents in electrodes used for electrostatic air conditioning apparatus of the kind described are exceedingly small, no great demands are made on the electrical conductivity of the adhesive material.
  • the type of construction adopted according to this invention has the further advantage that the electrically conductive layer is attached to the insulating layer without any additional interposed attachment means.
  • the invention has the further advantage that it is no longer necessary to provide additional attachment means between a contact connected to the voltage source, and the electrically conductive layer. It is merely necessary to adhere the contact to the electrically conducting adhesive layer, which automatically ensures an electrical connection therebetween.
  • a contact is provided on the surface of the carrier and adhered to the electrically conductive adhesive layer. Since the carrier is relatively stable with respect to deformation, it can therefore also serve as a carrier for the contact.
  • the insulating layer is a selfadhesive foil provided with an electrically conductive adhesive layer.
  • Such self-adhesive foils can be provided with a cover sheet to protect the adhesive until the time of use. The user need only detach the cover sheet and adhere the remaining self-adhesive foil via the adhesive onto the desired location of the carrier having previously interposed a contact. If such a foil is not used, then it is of cause also possible to apply the electrically conductive adhesive layer to the carrier, and then to adhere the insuulating layer to;the adhesive layer.
  • FIG. 1 shows a car 1, the interior 2 of which is provided with a seat 3 for the driver 4. Within the region of roof 5 there will be seen a roof electrode configura tion 6 with a roof electrode 7. If the positive terminal of a high voltage d.c. source 8 is attached to roof electrode 7, and the negative terminal of that source is connected to the chassis of the car, an electrostatic field arises having lines of force 9.
  • the lines of force 9 are concentrated in the region of the head of the driver, the exact configuration of the lines of force 9 depending on the position of the electrodes, the size and form of the intervening space between the electrodes, and other factors.
  • the novel electrode construction includes an insulated carrier 10, an electrically adhesive layer 11 and an insulating layer 12. Contact 13 is simply placed on the carrier 10 and adhered thereto with the adhesive layer 11 which adheres to carrier 10.
  • adhesive layer 11 acts as the electrode 7 as well as an attachment means for both the carrier 10 and the insulating layer 12. It also holds contact 13 in place and assures electrical contact between adhesive layer 11 and connecting contact 13.
  • FIG; 4 shows a self-adhesive foil 14, which is comprised of an insulating protective layer 12 and an electrically conductive adhesive layer 11, being addition.- ally covered by protective sheet 15. Part of selfadhesive foil 14, corresponding to the desired size of the electrode, is cut off, the protective sheet 15 is peeled off, and the self-adhesive foil 14 is finally applied to the carrier 10, after previously interposing the connecting contact 13.
  • Electrically conductive adhesive layers are available commercially.
  • an air conditioning apparatus comprising, in combination, first and second electrode means; a high-voltage DC. voltage source having terminals of opposite polarity respectively connected to said first and second electrode means for establishing therebetween a steady electrostatic field in the interior of said substantially enclosed habitable compartment, at least one of said electrode means comprising a carrier of electrically insulating material, a protective cover layer of insulating material facing the interior of said substantially enclosed habitable compartment, and a layer of electrically conductive adhesive material intermediate said cover layer and said carrier holding said cover in place on said carrier by adhesive force and being electrically connected to one of said terminals to serve as the electrode for said one of said electrode means.
  • said layer of electrically conductive adhesive material has two major surfaces and is adhesive at both said major surfaces and is held in place on said carrier by adhesive contact between said carrier and one of said major surfaces, and wherein said protective cover layer is held in place on said layer of electrically conductive adhesive material by adhesive contact with the other of said major surfaces.
  • an air conditioning apparatus as defined in claim 1, said compartment being bounded by at least one boundary wall structure, and wherein said one of said electrode means is mounted on said boundary wall structure, and wherein said carrier of electrically insulating material is mounted on but discrete from said boundary wall structure.
  • an air conditioning apparatus as defined in claim 1, wherein said protective cover layer and said layer of electrically conductive adhesive material are discrete from each other and have facing major surfaces which are in contact with each other substantially all over said facing major surfaces.
  • said one of said electrode means further includes an electrical contact member at least a portion of which is interposed between said carrier and said layer of electrically conductive adhesive material, said portion of said electrical contact member being covered by said layer of electrically conductive adhesive material and being electrically connected to the latter and serving to connect the latter to the respective one of said terminals.
  • said one of said electrode means includes a self-adhesive foil comprised of first and second adjoining parts respectively constituting said protective cover layer and said layer of electrically conductive adhesive material.
