Description
1~)61414 The invention relates to an apparatus for the ionization of the air in closed spaces, having a blower and an ion generator which are disposed in an air duct through whose discharge orifice a substantially unipolar air stream having preferably negative ions is delivered into the room.
It has been found that a person dwelling in an atmosphere enriched with unipolar ions experiences a positive influence on his well-being, on his capacity for work and on his health. Especially the breathing of air containing negative ions arouses the activity of numerous functions of the body. It is therefore known to aspirate the air in a living room by means lo of a blower, ionize it, and then reintroduce the ionized air stream into the room.
~ For many reasons it is not possible to remain throughout the day in rooms ionized in this manner. The invention is therefore addressed to the task of making it possible for virtually any person to be supplied with a sufficient number of ions in a manner that will be found to be pleasant.
This objective is accomplished by the invention through the association of an apparatus of the kind described above with a television receiver such that the discharge orifice disposed adjacent the picture screen will face in approximately the same direction as the picture screen.
The inventor set out from the consideration that even a brief exposure to ionized air produces the known positive effects if the inhalation of ions is intensive and ~miform. As it is known, most people sit daily for 30 minutes to 3 hours or longer before a television receiver. Each person, be he alone or in a group, has a more or less established position. If ionized air is blown into the room from the direction of the picture screen, a high concentration of ions is assured in the area of the seats. Further-more, the television viewer has his head turned to face the screen. The air the viewer breathes is aspirated, therefore, directly from the ionized air stream, and by and large he will absorb a large amount of ions.
1C)6~4~4 For the intended effect it matters little whether the ionizing apparatus is built into a television receiver so that the air discharge orifice is in the housing of the receiver, or whether two separate units are involved whose housings are placed adjacent one another. In particular, the possibility exists of equipping an available television receiver with an ionizing apparatus.
An apparatus which can be purchased separately from the television receiver in this manner is distinguished especially by the fact that one wall of the housing of the ionizing apparatus, which is disposed perpendicul-arly to the discharge orifice is matched to a wall of the television receiver which is perpendicular to the picture screen. In particular, this housing can form a base or a cap for the television receiver. In this method of combination the discharge orifice is above or below the picture screen, and therefore the distribution of the air can be symmetrical to both sides like the picture viewing angle, to serve a single viewer or a group of viewers.
Even so, the housing can be shallow, and it can have a horizontal width that is great in comparison to its height. Consequently, the space occupied by the ionizing apparatus is very small. Nevertheless, the apparatus can produce a very good distribution of the air.
The air duct can advantageously have a constriction in which the ion generator is disposed. This makes it possible for most of the blown air to pass through the active ionization zone which, as a rule, is not so very large. Since the air duct broadens again after the constriction, all of the air that emerges will have an approximately uniform degree of ionization.
The constriction can be followed by baffles for the lateral deflection of the emerging air stream? so as to distribute the ionized air among a plurality of persons seated together.
To special advantage, the ion generator has a small glow discharge lamp having a wire carrying high voltage direct current adjacent its glass wall. Such an ion generator, which is known from German Patent 2,260,521, has the advantage that neither o~one nor nitrogen oxide is formed, and that furthermore it requires little space in spite of its high ion yield. It can therefore be contained in even very shallow housings.
Television picture tubes operate at a relatively high anode voltage of, for example, 25 kV in the case of a color television tube. As a rule, therefore, an electric field previals directly in front of the picture screen, through which negative ions in the air are very intensely attracted. Normally, therefore, rooms in which a television receiver is operating are decidedly poor in ions. An additional advantage of the invention lies not only in the fact that its production of ions will increase the total ion content of the room, but also in the fact that, since the ionized air is flowing away from the picture tube, the ions are under the influence of a force which is opposed to the attractive force of the picture tube field, so that the ions actually do reach the viewer. If the force of this flow should be insufficient, air baffles can be provided to block the flow of air from the viewing screen, or shielding means can be provided to shield the negative ions emerging from the orifice from the picture tube field.
For example, the discharge orifice can be provided, on the side nearest the picture screen, with a baffle or shielding plate. It has been found that, when the discharge orifice is in the same plane as the picture screen, the baffle or shield plate must have a length of at least 20 cm, and preferably a length of 30 to 40 cm, to achieve optimum results. Also, the baffle or shield can be made retractable, so that it will not have to protrude beyond the plane of the picture screen when it is not in use.
A similar effect can be achieved by making the discharge orifice , protrude beyond the plane of the picture screen. This can especially be 1~61414 achieved by constructing the orifice such that it can be retracted telescope-wise within the housing. In this case it is desirable that the ion generator be located in the projecting or extensible part of the duct, so as to be at a fixed but not too remote distance from the discharge orifice, so that the emerging air will be intensively ionized.
It is especially advantageous for the shielding means, such as a shielding plate or prolongation of the duct, to be made at least in part of an electrically insulating material. A variety of plastics have proven suitable, such as, for example, phenol plastics in the form of fiberboard, or polyacrylic esters. If electrically conductive shielding means are used, they should be connected to a potential that is selected such that the negative ions will not be attracted to them.
If ion generators are used in which a high negative direct-current voltage is used, the emerging negative ions will be attracted by the ground potential; consequently, after they have left the discharge orifice they follow a slightly downwardly curved path. In order nevertheless to enable the ions to reach the level of the viewer's head, it is desirable that a field electrode be provided in the room in front of the television receiver and above same, and that this field electrode be connected to a high direct-current voltage that is positive with respect to ground. This direct-current field prevailing in front of the television receiver will exert an upwardly directed component of force on the negative ions.
Also, if provision is made to keep the television viewer himself at ground potential- for example by providing the seats in front of the television receiver with conductive coverings that are grounded--the downwardly directed portion of the ground field can be partially compensated.
It is also desirable for the air stream to be warmable by means of a heating system. The heating should be such that ~he air stream will not be felt as an unpleasant draft. As a rule, a temperature increase of 1 to 3C will suffice. Parts of the television receiver that develop heat can serve, for example, as the air heating means.
This can be accomplished in a simple manner by constructing the air ionizing housing for installation on top of the television receiver and locating the air intake orifice above the back part of the television receiver.
In a further development, provision is made for the housing of the ion generator to extend downwardly in the area at the rear of the television receiver to provide space for the accommodation of the blower. If the housing is too shallow to accommodate the blower, the free space which is as a rule available in television receivers in this rear area can be utilized for the purpose of providing the housing with sufficient space to accommodate the blower.
The rotatory speed of the blower can furthermore be adjustable so as to provide control over the delivery of ions to the room.
The housing can also contain a background lighting source, such as is recommended for television viewing; a separate light source can then be eliminated. If the blower motor and the background light source are connected in parallel, the light source can serve as an indicator of the blower speed.
The ion generator and blower are controlled remotely to special advantage, for example by ultrasonic pulses. The hand control device for the remote control can also contain an ion detector. A television viewer will then be able without leaving his chair not only to turn the ionizing apparatus on and off, but also to adjust it such that the ion detector will indicate sufficient ionization.
Thus, in accordance with the invention, there is ~ -5-provided apparatus for ionizing air in closed spaces, comprising a blower and ion generator which are disposed in an air duct through whose discharge orifice a substantially unipolar air stream having preferably negative ions is delivered into the room, in association with a television receiver, wherein the discharge orifice is disposed in the vicinity of the viewing screen of the television receiver and faces approximately in the same direction as the viewing screen.
The invention will now be explained with the aid of the embodiments represented in the drawing, wherein Figure 1 is a diagrammatic representation of a room containing an ionization apparatus in accordance with the invention, which is associated -5a-~061414 with a television receiver.
Figure 2 is a front elevational view of the ionization apparatus with television receiver, Figure 3 is a top plan view of the ionization apparatus with its top cover partially cut away, Figure 4 is an electrical diagram of the ionization apparatus in accordance with the invention, and Figure 5 is a side elevational view of another embodiment.
In a closed space 1 there is provided on a table 2 a television receiver 3 with a viewing screen 4. At a distance of 2.5 to 5 meters in fro~t of the viewing screen 4 there are provided seats 5 for one or more television viewers 6. Such an arrangement is found in virtually all homes.
In the television receiver 3 an ionization apparatus 7 is arranged such that a discharge orifice 8 for the ionized air is adjacent the viewing screen 4 and faces in the same direction as the viewing screen. In the embodiment represented in Figure 1, the housing 9 of the ionization apparatus is constructed as a bottom rest for the television receiver 3, its top side 10 being fitted to the bottom side of the television receiver 3, in the sense especially that it is of sufficient size, but it can also be fitted as regards its shape. For example, a step-like thickening 11 is provided in the rear portion of the television receiver, where adequate space exists for it. The housing 9 is shallow. The discharge orifice 8 has a great horizontal width in respect to its height. Between the discharge orifice 8 and the viewing screen 4 there is a shielding or baffle plate 12 which can be extended out of the housing 9 to a distance of 40 cm.
The internal construction of the ionization apparatus 7 can be seen diagrammatically in Figure 3. Within the housing 9 there are side walls 13 and 14 which define an air duct 15. In this air duct the following are arranged successively between the intake orifice 16 and the discharge 1061~14 orifice 8: a blower 17 with its corresponding motor 18, a heater 19 and, in a constricted portion 20, an ion generator 21. me ion generator has a small glow discharge lamp 22 on whose circumference a fine wire 23 lies which is supplied by a high-voltage source 24 with a negative high voltage -Ul of, for example, -3 kV. Furthermore, baffles 25 can additionally be provided between the constriction 20 and the discharge orifice 8 to spread out the air being discharged.
Furthermore, in the housing 9, within the step-like thicker portion 11, there is provided a light source 26. Also, a receiver 27 is provided which has a receiving aperture 28 which responds to an ultrasonic remote control pulse. An ultrasonic remote controller 29 operates similarly to a television receiver remote control device. It has transmitting devices with corresponding keys for turning on and off the blower 17, the heater 19 and the ion generator 21, and also, if desired, for changing the blower speed and the heater output. Also provided in this remote controller 29 is an ion detector 30 which indicates when a sufficient amount of ions is present in the vicinity of the viewer 6.
In the circuit given in Figure 4 it can be seen that the ionizing device can be turned on by means of a main switch S. This also activates the receiver 27, with which three switches 27a, 27b and 27c are associated, which can be actuated by various ultrasonic pulses. By means of switch 27a, the glow discharge lamp 22 and simultaneously the high voltage power supply 24 are connected to the mains voltage which lights the glow discharge lamp.
The high voltage power supply 24, which has, for example, a cascade rectifier circuit, produces a negative voltage -Ul of such a magnitude-~ - 3kV for example -that on a fine wire 23 a field strength will prevail which is not quite sufficient to produce a brush discharge. Under the influence of the ultraviolet radiation of the glow discharge lamp, however, the energy level at the fine wire is raised to such an extent that ions are produced.
Virtually naught but negative ions are produced in this manner, since positive ions are hardly able to escape the strongly negative potential of the wire 23. By means of switch 27b, the blower motor 18, and parallel thereto the background light 26, are energized. By means of input resistances 31a and 31b, different speeds of the blower 17 can be set, which simultaneously results in different levels of brightness of the background light. Switch 27c selectively energizes one or two heating resistances l9a and l9b.
The peripheral surfaces 32 of the room 1 are grounded. me chair 5 has a covering 33 which is also grounded. In front of and above the television receiver 3 there is provided a ceiling electrode 34 which is mounted on the ceiling by means of an insulator 35. This electrode is maintained at a positive voltage +U2, amounting for example to 8 kV.
mis results in the following manner of operation. Air is aspirat-ed from the room by the blower 17 through the air intake orifice 16, and it is heated by the heater 19 and charged with negative ions in the ion generator 21. A variety of forces act upon the ions. Mechanical driving forces act on them in the horizontal direction due to the air stream.
Insofar as the field between the ground and the wire 23 charged with negative high voltage reaches, the ions are attracted downwardly by the floor of the room, which is at ground potential, and horizontally toward the viewers 6 who are also maintained at ground potential due to the grounded covering 33. The influence of the field prevailing between the ceiling electrode 34 and the grounded walls 32 defining the room gives the negative ions an upward attraction. The shield plate 12 prevents the field at the picture tube 4 from exerting an undesirable influence on the negative ions.
The overall effect, therefore, will be an area of maximum ion concentration .
as indicated approximately by the broken line 36. W~hereas normally virtually no negative ions at all are to be found at a distance of 5 meters from the 10614~4 viewing screen, ion concentrations of at least 10,000 ions per cubic centi-meter have been determined at a conventional distance of the viewer 6 from the television receiver 3 when the apparatus of the invention was in use.
In the embodiment represented in Figure 5, the ionization apparatus 37 is in the form of a top-mounted attachment for the television receiver 3. In this case the bottom 38 of housing 39 is matched to the television receiver~ A duct portion 40 in which the ion generator 21 is located at a fixed distance from the discharge orifice 8 is adapted for extension from the housing 39. The air intake orifice 41 is provided on the underside of a step-like thickened portion 43 such that the air, as indicated by the broken lines, is aspirated from the interior of the television receiver 3. In this manner a special heating means is unnecessary. The air is blown not by an axial fan as in Figure 3 but by a tangential blower 43. The high voltage is fed to the ion generator 21 from the tap 44 of a voltage divider consisting of the high-ohmic resistors 45 and 46, which is connected between the output of an alien high-voltage power supply, e.g., one which is present for other reasons, but which is not shown in detail, and the ground. The telescoping duct portion 40 consists, like the baffle or shielding plate 12, of an electrically insulating material. Preferably, the housings 9 and 39 are also made of such a material.
Instead of the blower represented in the drawing, a radial blower can be used, which is advantageous especially in conjunction with the constriction 20, because the output is affected to a lesser extent by resistances in the air duct.
It will be understood that the specification and examples are illustrative but not limitative of the present invention and that other embodiments within the spirit and scope of the invention will suggest themselves to those skilled in the art.

W~hereas normally virtually no negative ions at all are to be found at a distance of 5 meters from the 10614~4 viewing screen, ion concentrations of at least 10,000 ions per cubic centi-meter have been determined at a conventional distance of the viewer 6 from the television receiver 3 when the apparatus of the invention was in use.
In the embodiment represented in Figure 5, the ionization apparatus 37 is in the form of a top-mounted attachment for the television receiver 3. In this case the bottom 38 of housing 39 is matched to the television receiver~ A duct portion 40 in which the ion generator 21 is located at a fixed distance from the discharge orifice 8 is adapted for extension from the housing 39. The air intake orifice 41 is provided on the underside of a step-like thickened portion 43 such that the air, as indicated by the broken lines, is aspirated from the interior of the television receiver 3. In this manner a special heating means is unnecessary. The air is blown not by an axial fan as in Figure 3 but by a tangential blower 43. The high voltage is fed to the ion generator 21 from the tap 44 of a voltage divider consisting of the high-ohmic resistors 45 and 46, which is connected between the output of an alien high-voltage power supply, e.g., one which is present for other reasons, but which is not shown in detail, and the ground. The telescoping duct portion 40 consists, like the baffle or shielding plate 12, of an electrically insulating material. Preferably, the housings 9 and 39 are also made of such a material.
Instead of the blower represented in the drawing, a radial blower can be used, which is advantageous especially in conjunction with the constriction 20, because the output is affected to a lesser extent by resistances in the air duct.
It will be understood that the specification and examples are illustrative but not limitative of the present invention and that other embodiments within the spirit and scope of the invention will suggest themselves to those skilled in the art.
