Air purifier to be placed on convection radiators

The invention relates to a convection heater to be placed on Air cleaner.

It is known that, especially in winter, when the house rezers are in operation, the number of pollutant particles contained in the air increases. In heated interiors, this air is kept in constant circulation by convection radiators, namely, the air heated by the convection radiators flows upwards, generally up to the ceiling deflected there and then flows down somewhere inside the room and comes back into the catchment area of the convection radiator. The well-known, very intensive dirt deposits on the wall and ceiling in the area above the radiator clearly show that in this area by the enhanced

609323/0150

Air movement on the one hand, on the other hand through the lowering of the relative humidity of the air, which results from the heating on the radiator, and through a kind of "roasting process", especially with radiators operated with high flow temperatures, the possibility of adhesion of the dirt particles is increased. To ^; Trouble of those who have to keep the rooms clean, e.g. the housewives, these dirt particle deposits are practically inevitable up to now, radiators are mostly located below the windows in the usual buildings, so that blinds and curtains that are in front of the windows are right need to be washed frequently or even replaced. In addition, wallpapers, plaster, etc. in the area above the radiators require constant maintenance or even renewal. Due to the strong convection effect, even window dirt particles are kept in circulation until they have deposited themselves everywhere in the room, so that considerable cleaning and maintenance work is required in the other areas of the heated room.

It is therefore the object of the invention to create an air cleaner that can be attached to a convection heater and that is as large as possible Part of the air that is heated by the radiator. rises, traps contained dirt and dust particles. at The solution to this problem must take into account the fact that such an air cleaner work with the lowest pressure drop!

must, because the pure convection flow of the!

Radiator air did not produce any noticeable overhead;

pressure or in the presence of excessive flow resistance of the device would not flow through this device but by it. There are therefore fine filters, their passage openings are smaller than the dirt particles to be collected are out of the question. Such fine filters with their strong Flow resistance would greatly reduce the heating effect of the convection heater because then the flow along the heater No more air up to the top along the radiator surfaces but would break out in all directions. This would make the effective heat exchange area of the radiator strong degraded. In addition, such a fine filter would be practically ineffective because only a negligibly small amount of air would pass through this filter.

Devices that can be placed on convection radiators are now already available known, the main task of which is to increase the humidity in the heated room. These devices, also called humidifiers, contain most of the; flat sheet made of absorbent cardboard Element that is either completely flat or bent once by 90 ° for reasons of water absorption. The absorbent cardboard takes water from a water storage box through capillary action and is therefore always moist. On the damp surface this flat element, which faces the convection radiator, is of course also some in the upstream Dirt particles contained in the air are retained, but the proportion of these particles retained is compared with the Total amount of dirt particles contained in the outflowing air, extremely small, and once this surface has been removed

6 09829/015 Cl

If dirt particles are occupied, there is no retention at all of dirt particles more. Therefore, the air cleaning effect attributed to some of these devices is practically the same Zero.

Taking into account the basic physical conditions described is therefore the underlying task of the invention, a real, i.e. really effective air purifier to create that can be placed on convection radiators, using flat elements that form part of the Hold smear particles on their surface as the heated air exiting at the top of the radiator flows along, solved according to the invention in that the flat elements are formed by tracks or strips with rows of holes, the are offset from the adjacent rows of holes, made of a flat material with an outer surface that binds dirt particles (without With the help of permanent moistening of these flat elements), whereby these tracks or strips along horizontal, Glued together transverse lines running in the direction of the radiator depth and possibly parallel to the glue lines are folded, in such a way that when pulling apart a package formed in this way in the longitudinal direction at least two superimposed, each other by half their pitch staggered and nested rows of in vertical and transverse closed chambers arise.

609829/01 BfI

The chambers \ formed in the inventive air cleaners have a relatively large internal surface area, and in them \ results in a strong air turbulence at relatively low air resistance. The air flowing upward through a flat element of the air cleaner according to the invention first passes through the;

'Holes in the lower chamber into the interior of the chamber and can only move upwards by flowing laterally within the chamber into an adjacent chamber. From there the air comes out again, with transverse movement, through the perforations of the nested chamber above it flat element. In doing so, there is inevitably a vortexing of the outflowing air at the entry as well as at the Exit from the lower chamber and again at the entrance! and when the air emerges from the chamber above. At ; This alternating acceleration, swirling and deceleration of the flowing air removes the dirt particles from the overall direction of flow carried out by the air and come into contact with the surfaces of the flat element, which is a dirt particle has binding outer surface. In the design and arrangement of the planar element according to the invention, both of these come

! External surfaces in contact with the air flowing through, and not jonly, as with the known humidifiers, the one outer surface.

iThis increases the degree of utilization of the flat elements, which yes,

! as with humidifiers, thrown away and replaced with new ones ! Items are replaced, increased by 100%.

The effect of binding the dirt particles on the outer surface of the flat element, so to speak the adhesive effect, can be achieved in a variety of ways. One possibility is that the flat element is on both sides is coated or soaked with a material capable of creeping as a film. This then has the effect that at Impact of a dirt particle on this surface this also covered with a film due to the creeping property of the material applied or soaked as a film will. This means that particles that are already adhering, which then belong to the outer layer of the flat material, become additional Surfaces that can absorb dirt particles. The receiving surface of the flat material is then not reduced by the impact and retention of dirt particles, but rather increased.

It is, as an example, also possible, the flat element on both sides with a material that flows through the Air experiences an electrostatic charge, to be coated as a film or to be soaked with this material.

The prerequisite for the two options listed is the achievement of an adhesive property on the flat Elements that bind dirt particles flowing past to the flat material. Materials

609829/0150

of the appropriate type, both creepable materials and materials causing an electrostatic charge known, so that there is no need to give examples.

It now depends on the main part of the invention Air purifier, and that is the "flat element", and also to be able to manufacture the carrier for it as cheaply as possible, because it is supposed to be one of everyone's homes with central heating, and that is the main part today of all apartments, bargain affordable items. For this reason, it is necessary to manufacture processes for the flat elements according to the idea of the invention through as possible to be able to produce economical manufacturing processes. There are a number of ways to do this; two of them should in the following, i.e. examples, are described.

A method of manufacture proposed by the invention of the flat element of the air purifier according to the invention in that one panel, one row of holes in succession, then a fold line with a crest pointing upwards, then two rows of holes, then an adhesive strip on the underside, then a row of holes, then a fold line with a comb down, then two Rows of holes, then an adhesive strip on the top, and this then repeated in the same order, by folding over around the fold lines, in the specified direction, meandering or folded in a bellows shape, then pressed together and after the bonded joints have solidified on the adhesive strips

609829/0150

is pulled apart. In this production method results a double stacking system of stacked, with the exception of the side outlets, closed chambers with two rows of holes each.

In this process, the adhesive strips must be attached alternately to the top and bottom of the web. It is also possible to manufacture the flat element of the air cleaner according to the invention in such a way that the adhesive strips only attached to one side of a continuously manufactured web Need to become. In this production method, according to the invention, a web is successively a first Adhesive strip, then two rows of holes, then a second adhesive strip on the same side as the first adhesive strip, and then a row of holes, and this is then repeated in the same order, in each case between the individual row of holes and the edge of the next adhesive strip facing this cut in the transverse direction; the resulting After every second strip has been pivoted through 180 ° in its own plane, strips are pressed against one another, and the package thus formed is after solidification of the adhesive bonds on the adhesive strips in pulled apart to the faces of the strips perpendicular to the direction. This creates, without the need for Fold lines (these are replaced by the adhesive points) create a flat structure that is practically the one described above Process created structure corresponds exactly.

609829 / 01S0

Those according to these] procedures, or according to other comparable ones Flat elements produced by a method are created by pulling them apart in the transverse direction. They exist, as a basic substance, made of paper or cardboard and therefore have a certain elasticity. It is therefore necessary to somehow use these elements to be fixed in the desired end position. In addition, you have to attach these elements to the conventional radiator in some way and also fix them. To this end a receiving frame for the flat element of the air cleaner is proposed according to the invention, which is characterized is that it is formed in the form of a rectangular box in plan view from two short and two long sides is. The two short sides have a length at least equal to the depth of the radiator, so that they can be pushed onto the radiator, and have at their upper edges pins for pushing at least one part of the holes of the outermost row of holes of the flat element. This will make this flat element in the desired Fixed apart in this mounting frame. There can be tenons for each hole in the outermost row of holes, however also only pins for every second, third, fourth hole, etc. can be provided. The two long sides that are in the Length have a selected standard size for the device (for example, a standard size of 50 cm is possible), are more prominent below About the resting on the top of the radiator

609829/0150

Bottom edges of the short sides of the rectangle of the mounting frame considerably before. This causes the rising air in the convection heater at least is largely prevented from flowing laterally past the air purifier. The frame is with a corner diagonally and / or obliquely between its two long sides, preferably parallel to the diagonals,

running support strips for the flat element and for supporting the entire frame on the top of the radiator Mistake. This ensures that the mounting frame and thus the entire air cleaner without tilting, Inclined seating or the like. Can be placed on radiators of any pitch, rib size, etc.

In winter, when there is a low relative humidity in heated rooms, but a high one Convection on and above each radiator, the entire indoor air is several times within a day Air purifier and is transported through the

Retention of dirt particles cleaned. A clear one Reduction of pollution in the area of the radiators, especially above them, but also a significant one Reduction of pollution at all in the concerned

Objects located in the room is the result.

In the two manufacturing processes described for the flat Elements of the air cleaner can be the application of the dirt particle-binding outer surface either before or after gluing take place. The folded package is packed airtight in appropriately welded bags and brought to the consumer. the Width of this package is the customary depth dimensions of the usual Adapted radiators. The length to which the package is drawn out is not fixed; but it should be chosen so that when taking off an opening angle of no more than 90 ° is created on the folding combs and on the adhesive strips. Appropriately, one becomes one Choose a standard length, for example 50 cm. With wider radiators you can then, if necessary, several air purifiers after the Provide invention.

The air cleaner according to the invention has one per unit area very large passage cross-section, and therefore a low flow resistance, but a very large outer surface, which is used as an adhesive surface serves to hold on to dirt particles. The less the package is pulled apart, the more the relationship shifts of the passage cross-section per unit area to the adhesive area per unit area in favor of the adhesive area, so that with only small Upper pressure of the incoming air, as it is with low or with only enters at a low temperature heated radiator, the package can be pulled apart longer and thus more passage cross-section offers. Conversely, if the radiators are operated with a high flow temperature or a fairly high flow temperature, a higher Offer air pressure, the package will be less pulled apart.

The degree of soiling of the flat element of the air cleaner can be determined optically. After reaching a certain Soiling degree, after which the cleaning effect then decreases, the used flat element is thrown away and replaced by a new element.

In the manufacturing processes described, it was assumed that that each chamber in the flat element is two on top of each other! should have legendary rows of holes. It goes without saying It is possible to provide chambers with more rows of holes, with appropriate shifting of the folding and / or adhesive strips.

In the drawing are exemplary embodiments of the invention shown.

In the sheet-like starting material according to Figure 1, a row of holes 1, then a fold row F, with a comb upwards, then two rows of holes 2, then an adhesive strip K ₂ on the underside, then a row of holes 3, then a fold line ? 2 ^{with a} comb follow one another at the bottom, then two rows of holes 4, then an adhesive strip K ^ on the top, and this is then repeated in the same order in the strip. The successive rows of holes are offset from one another by half their pitch. After the corresponding folds have been carried out on the fold lines F 1 and F 1, the web is folded in a meandering or bellows shape to form a package, which is then compressed. After the adhesive bonds on the adhesive strips K 1 and K 2 have solidified, the web is then pulled apart and then attains the shape shown in FIG. In this form, the flat element then has the form of two superposed, nested rows of vertically and transversely closed chambers, of which the chambers of the lower row are denoted by 5 and the chambers of the upper row are denoted by 6. The chambers 5 and 6 of this flat element are open on the sides, but are practically closed by being inserted into the receiving frame, which will be described in more detail below with reference to FIGS. 6 and 7.

The method according to FIGS. 3, 4 and 5 is based on a path that is shown in FIG. This has successively an adhesive strip K ^ on the top, then two rows of holes 2, then again a second adhesive strip K ₁ also on the top and then a row of holes 1. This web is then cut in the transverse direction in each case between the individual row of holes 1 and the edge 7 of the next following adhesive strip K facing it. Each of the resulting individual strips, three of which are shown in FIG

ο second pivoted by 180 in its own plane. Through this the strips then move into the position shown in FIG. The strips are now pressed together until the adhesive bonds are solidified on the adhesive strips Kj. Afterward the package formed in this way is then in the direction perpendicular to the surfaces of the strips, i.e. in the transverse direction in FIG. pulled apart. This creates a flat element according to FIG. 5.

The mounting frame shown in Figures 6 and 7 for flat Elements, regardless of how they have now been produced, have the shape of an edge that is rectangular in plan view from two short sides 8 and two long sides 9. The two short sides 8 have at least the depth of the radiator corresponding length and have pins 10 on their upper edges

The two long sides, which have a selected standard size of, for example, 5ocm in length, protrude downwards over the on the Upper side of the radiator resting lower edges 11 of the short sides 8 in front. : Oer frame consisting of parts 8 and 9 is with diagonally running support strips 12 and in addition with support strips 13 running obliquely between the two long sides, specifically parallel to the diagonals 12 Mistake. The inclined angle of the diagonal support strips 12 and the cross connecting strips 13 to the frame sides 8 and 9, respectively is 45 °. With these support strips, the frame 8, 9 is placed on the top of the radiator, so that it is safe comes into an exactly horizontal position when placed, regardless of the division and shape of the radiator ribs.
