The electrodes (3a, 3b) are connected to an electric power unit, preferably by means of a high voltage cable (4).

Description

APPARATUS FOR IMPROVING THE AIR CONDITION OF SPACES

The invention relates to an apparatus for improving rooms by means of which the air humidification, the air humidity control and the simultaneous ion conditioning of rooms used for the stay of people in the heating season and also outside of it - i.e. all year round - can be solved effectively and efficiently.

The health effects of natural air (especially mountain and forest air and the air on the beach by water) are generally known, but are not so well known - although the population of the highly developed northern hemisphere has the majority of their lives in closed Spends clearing - that in the rooms serving the stay of people numerous effects affecting the general well-being and harmful to health come into play. The main characteristics of the natural good air are the optimal temperature, the optimal air humidity, the corresponding ion concentration and the corresponding ozone content as well as the Air cleanliness. Of these factors, only securing the corresponding temperature in a wide range (especially in the heating season) can be regarded as solved. The cleanliness of the air in the premises is largely dependent on the so-called mezclimate, ie the surrounding urban conditions, but with the poorest climatic conditions, it is by no means necessary to forego the successful improvement of the indoor climate - the so-called microclimate .

It is necessary for numerous reasons to ensure the appropriate air humidity (moisture content) in the rooms used for human residence. In particular, the low air humidity can dry out the mucous membrane of the upper respiratory tract and therefore reduce its resistance, continue to cause skin itching and thirst . These two latter phenomena can be supplemented by other causes (e.g. unfavorable ion ratios) that cause fatigue, insomnia and headaches. Children, in particular, younger than three years and old people are particularly sensitive to dry air; The cause of a permanent asthma developing into adulthood can be, for example, the fact that the patient stays permanently in a dry apartment in childhood. hold. At the same time, however, the excessively high relative moisture content of the air is also disadvantageous, since this confuses the heat balance of the human organism; however, the droplets of a liquid atomized in the air may contain pathogens that are very dangerous to health.

Recent bioclimatic research has drawn attention to the fact that the biological effects of air ions on the human organism are of paramount importance and that within them the light air and ozone ions have an especially beneficial influence on the air quality of the premises exercise. (It should be noted here that over the course of millions of years the human sex developed in an atmosphere in which air ions were always present and in the atmosphere more ozone was found than today.)

In such closed rooms, in which people reside, the amount of light ions decreases considerably over time, because some of them are bound to the surface of objects, some of them are for the human organism convert harmful heavy ions; the latter process takes place in for premises with low air humidity, which characterize the heating period, dry more quickly. The heavy positive ions which characterize the microclimate of such rooms have an unfavorable effect on general well-being, cause psychological tensions, increase blood pressure, reduce the alkaline reserve in the blood and the cilia of the respiratory tract and contribute to an increase in the feeling of air dryness. The light negative ions, on the other hand, exert the opposite of the above-described adverse influences of significant advantageous effects.

From the above, it is clear that in the interest of securing the appropriate microclimate in the premises, good general health and a healthy environment, the two most important factors are the optimal air humidity and ion concentration, and although this fact is generally known (e.g. If the air in spaceships and in atomic submarines is also ion-conditioned), no device is currently known which would be suitable for simultaneously fulfilling this dual task at a rational cost and simple construction.

The devices available on the market, which are only used for air humidification, e.g. steaming trays are, so to speak, perfect ineffective. The fairly costly electrical atomization humidifiers are effective, but there is a risk that they will humidify the air in the room to an excessive extent, being sensitive to the water quality and occasionally quite noisy.

Relatively inexpensive devices also came onto the market, but these must be arranged close to the user (for example the sleeping child, the person working at a table, they are generally attached to the lamp). Apart from this inconvenience, the fact that the ion and ozone concentration near the person's head can become larger than necessary also causes a problem, which can affect the general climate.

More expensive ionizers are also known which are not burdened by the disadvantages described above and which also contain filters for cleaning the air. Nevertheless, they do not perform the humidification task, and their price is so high that this practically prevents their spread in a wide range.

In the Hungarian patent specification

Reg. No. 195.572 describes an evaporator apparatus, in the liquid container of which vertical channels are provided to secure the thermal air flow and parallel to these are made of hygroscopic material evaporator inserts. These inserts reach up to the maximum water level of the liquid container and from the surface of which the water vapor escapes without water atomization and nevertheless intensively escapes into the upward flowing air. The vessel is closed with an aesthetically designed, perforated lid, the free cross section of the perforations (air passage openings) being at least as large as the openings of the air channels of the water tank vessel and being arranged above it. But this vaporizer is also not suitable for ion conditioning the room.

With the development of the present invention, the object was to provide a device which is simple in its construction and mode of operation and which is relatively inexpensive and which at the same time is able to ensure the optimal humidification and also the ionization of the air in the room.

The invention is based on the knowledge that in the event that the ionization is carried out directly in the vapor-enriched air stream, so-called hydrated ions can be generated, which are much more stable than the normal ions (formed in dry air) and are therefore more biologically favorable than this are, so that the required amount of ions can be secured even with small device dimensions and low energy consumption. According to further knowledge, the aforementioned vaporizer apparatus, which corresponds to the Hungarian patent specification Reg. No. 195,572, can be combined extremely simply and advantageously with ionizer components, so that a combined apparatus which is hydrated by the generation can be realized at minimal cost Ione-secured ion conditioning approaches the ionic conditions of the area in question to a high-quality natural state (eg alpine mountain climate). On the basis of the above findings, the object was achieved in the sense of the invention by means of such an apparatus, which is a vessel which can be locked with a lid, a water space, is carried out through the water space, but is separated from it, is open at the top and in the has several air guiding ducts opening under the cover and hygienic or absorbent properties that can be used between the various types of inserts, which can be used to extend massively up to the cover over the upper edge of the ducts, and in the cover - advantageously in the Line of channels - air vents are provided, the essential feature of The apparatus consists in that it has one or more pairs of electrodes which reach into the space located under the cover and are arranged above the water space and serve for ionization, the electrodes - appropriately by means of a high-voltage cable - with an electrical power supply device are connected.

According to an advantageous embodiment, the cable and the electrodes are attached to the inner edge of the cover.

It is also expedient if the apparatus is equipped with a negative polarity, high voltage, low-power electrical discharge, which can be expediently connected to a mains socket, to a mains connection device.

Finally, it is characteristic of another advantageous embodiment of the invention that it has an auxiliary apparatus which is provided with a housing for receiving a fan and is delimited at the top and bottom by a perforated plate; in the housing there is a removable air filter insert under the upper perforated plate, next to the fan there are guide plates for the air flow directed upwards and inwards and above the perforated plate there is a plate for holding the Vessel supporting part arranged. The invention is further described on the basis of the attached drawings, which contain an advantageous exemplary embodiment of the same. On the drawings are in

to see.

The apparatus of Fig. 1 and Fig. 2 has a tergefäß designated as a whole with the reference number 1, which can be completed with a removable and re-attachable lid.

Through the water space 18 of the vessel 1 - in which the maximum water level was designated with the reference number 11 in FIG. 2 - pass channels 10, 10a open and open at the bottom and top, but not connected to this water space, which allow the air to flow through. whose inlet openings 20 are arranged in the base plate of the vessel 1, their outlet openings 21, on the other hand, are arranged above the maximum water level 11, since the channels 10, 10a reach beyond this water level. The elongated openings 10, 10a 'formed in the lid 2 (see also FIG. 1) are in register with the channels 10, 10a when the lid 2 occupies its best (operational) place on the vessel 1.

The outer channels of the channel groups formed by four channels were designated with the reference numbers 10, the two inner channels with the reference numbers 10a.

The hygroscopic inserts 9 are pressed into the gaps, which are open on both sides and communicate with the water space 18, between the adjacent elongated channels 10, 10a, which extend to the profiled lower surface of the cover 2 and their upper end inserts a recess designed for this purpose (Fig. 2). 2 that the majority of the inserts 9 are exposed in the space delimited by the cover 2, as a result of which they can come into contact with corresponding surfaces with the warm air flowing up through the channels 10, 10a.

In the cover 2, a shielded high-voltage cable 4, which is arranged along the inside of the cover, is embedded in an electrically insulating material. The cable 4 is with its free end led out of the cover to a Metzger 5 connected, which contains the voltage multiplier electronics and the contact protection components. The ionization is carried out by the electrode pairs 3a, 3b arranged under the openings 10 'of the cover 2, reaching into the space delimited by the cover and located above the vessel 1 and connected to the aforementioned cable 4 - in the case of the present exemplary embodiment A total of four electrode pairs - secured, at which a negative polarity, high voltage (expedient approx. 6 kV) and low power (approx. 0.1 W) exhibiting electrical discharge takes place. The electrodes 3a, 3b are fastened with the aid of the inserts 6 formed from glass fiber-reinforced printed circuit boards, the breakdown protection of which is secured by an insulating layer made of synthetic resin. The above can also be realized in a different arrangement and embodiment, for example 4 x 2 electrodes can be arranged on one side at the two extreme openings 10 '. In this case, the inner part of the entire cover 2 must not be poured out with insulating resin, but only a printed circuit board 6 carrying the electrodes must be prefabricated and insulated.

The openings 8 (FIG. 1) formed in the central region of the lid 2 are provided for filling water into the vessel.

1 and 2 radio- works in the following way:

The vessel 1 is filled with water up to the maximum water level 11 and placed on a radiator (not shown) and the mains connection device 5 is plugged into the electrical mains socket. The low-ion, dry, warning air flows upward in the channels 10 and 10a in accordance with the arrows a drawn in FIG. 2, and these air currents tear the water particles sucked out of the vessel 1 through the inserts 9 with the arrows b. The air flowing up through the intermediate channels 10a and exiting the apparatus through the openings 10a 'into the room already ensures the required or optimal or approximately optimal moisture content of the air. (The water transfer or wetting area of the inserts 9 works independently of the maximum water level 11.)

Not only does moisture enter the air flowing upwards through the outer air passage channels 10 in accordance with the arrows b mentioned, but the ionizing electrodes 3a, 3b (pairs of electrodes) also ionize the air flowing upwards (the ions are in one in FIG. 2) rough enlargement illustrated and designated with the reference number 22), ie that the air flowing out of the apparatus according to the arrows e is not only humidified but also ionized. Because the humidification and If the ionization takes place at the same time, so-called hydrated ions occur, which is much cheaper from a biological point of view than if the air in the room were humidified or ionized with independent devices.

The ionizing power of the apparatus according to the invention can be, for example, approximately 4x10 ¹³ ions / sec, which ensures an ionic climate in the rooms which is characteristic of the alpine mountain air. In this way, the oxygen uptake of the people in the room increases, which improves general well-being and thermal tolerance, increases physical and mental performance, insomnia and sensitivity to the effects of the weather and generally reduces the nervousness that The organism's resistance to numerous diseases increases. The number of germs floating in the air is falling and with it the number of contagious diseases. The ozone ions that are created also destroy and neutralize some of the airborne pollutants.

The above-described embodiment of the apparatus corresponding to the utility model is operated mounted on the radiator, on the other hand it is conceivable that another embodiment for air conditioning of unheated rooms, to a small extent to regulate the air humidity (in some cases to reduce the moisture content). In this case, the inserts 9 have no hygroscopic but absorbent properties, their material can be, for example, zeolite or a mixture based on zeolite, and these inserts can also be changed daily. The air flow required in this case is shown in FIG.

has standing on the feet 12a housing 12 in which a ventilator 13 is arranged. In terms of construction, this ventilator 13 is a so-called ventilator ventilator, which is equipped with a speed-controlled (not specifically shown) cross-flow drive motor. Arc-shaped guide plates are installed in the housing 12, the housing 12 is closed at the bottom by the perforated plate 15a and at the top by the perforated plate 15b. A removable air filter insert is installed under the upper perforated plate 15b, which can be cleaned and / or replaced. The supporting part 17 is arranged above the perforated plate 15b, into which the apparatus according to FIGS. 1 and 2 can be inserted by simply connecting but nevertheless airtight, by means of which the device labeled k drew - filtered, cleaned - air flow which - if the inserts have 9 absorbing properties - removes the superfluous or desired part of the excessively high moisture content from the room air and at the same time ensures the required ion concentration of the air.

The greatest advantage of the utility model described above is that it is at the same time able to ensure the optimum moisture content in an extremely effective manner, and on the other hand to ensure ion conditioning in the room. In the heating season, the device can be operated on the radiator or convector, but outside of the heating period it should be conveniently arranged close to the center of the room (e.g. on a shelf or wall bracket) so that the free access or Implementation of the vertically upward air flow is guaranteed. In this way, the uniform ion concentration - the uniform distribution of the ions - in the given space can be ensured by using the thermal air flow coming from the radiator or convector during the heating period. (In the case of known ionizers with a similar determination, the transfer to people based on the polarity difference has not proven itself.) A major advantage The invention is the simultaneous air humidification and ion formation or the combination of these functions, since consequently on the one hand the hydration ions which have already been mentioned several times and which are extremely beneficial for health can be produced, and on the other hand the production price in such a mass by rational combination of the two functions it is reduced that a widespread distribution and a corresponding distribution of the apparatus can be achieved.
