Definitions

  • the present invention relates to an arrangement for improving ventilation indoors, which allows air flow from an air device to be preheated and distributed.
  • the air devices comprise a complete unit made of sheet metal.
  • the (overall) depth of the air devices varies as does their minimum height behind the radiator.
  • radiators Since older radiators are usually fitted less than 22-30 mm from the wall and there is also often a window-sill, it is necessary to remove the radiator in order to be able to fit the outside air device. This necessitates extensive installation work.
  • An object of the present invention is to partially or entirely solve the aforementioned problems by providing an arrangement which:
  • this object is achieved by an arrangement for fitting between a wall and a radiator arranged on a wall in order to improve the indoor ventilation, which arrangement will allow an air flow to be heated and distributed and which has the characterising features specified in claim 1 below, with preferred embodiments being set forth in the dependent claims.
  • the arrangement according to the invention is characterised in that it comprises a first part and a second part which are joined by a flexible duct.
  • the air device improves indoor ventilation and allows incoming air to be heated and distributed. It is easy to fit the air devices behind a radiator without having to remove either the radiator or the window-sill, and the fact that the duct can be made to the desired length without affecting other functions makes it possible to adjust the air device to the height of the radiator.
  • the first part is a filter box for filtering said air flow from an air inlet to the duct and having a filter hatch for changing the filter.
  • the fact that the air flow contains particles such as pollutants and many different types of pollen means that for many people there is a great need to be able to filter out such substances which present problems, primarily for allergy sufferers but also for the public at large.
  • the incoming air flow is filtered at an early stage and it is very easy to change filters and when necessary to clean the filter device.
  • the second part comprises at least one expeller opening for expelling the air flow towards the radiator, the expeller opening moreover being designed to guide the air flow along the rear side of the radiator, which heats the incoming air flow and prevents cold draughts along the floor.
  • the arrangement is designed so that the incoming air flow is delivered at high velocity and is angled upwards behind the radiator.
  • a high velocity is important in order to prevent the cold air in wintertime "dropping" down below the radiator due to the high density of the air. If this should happen it results in cold draughts along the floor.
  • Another important effect achieved by a high velocity delivered air flow is that the air flow then also expels the indoor air, that is to say it entrains the indoor air in proximity to the lower parts of the radiator. This means that warm indoor air mixes effectively with the cold outside air, which means that the temperature of the mixed air flow increases. This effect is particularly important in autumn and in spring when the temperature of the outside air may be low whilst the heating system is not in operation. During the heating period the air flow is also heated by the hot radiator.
  • the air flow be allowed scope for proper warming by the radiator in that the air flow blows out towards the lower parts of the radiator. It is not effective, for example, to use an air device 230 mm behind a radiator which is 600 mm high. Since the arrangement according to the present invention allows the air flow to blow out against the lower parts of the radiator, this provides efficient heating of the outside air, since the air flow is forced to flow such a long distance along the radiator.
  • the flexible duct is a substantially airtight fabric and the second part is suspended behind the radiator in the duct and the duct is suspended behind the radiator in the first part.
  • the arrangement according to the present invention comprises three parts assembled into one unit.
  • the arrangement has a depth, also known to the person skilled in the art as the overall depth, of approximately 17 mm, which corresponds to the minimum dimension encountered between radiator and wall. Its height behind the radiator is adjusted so that the largest possible proportion of the radiator is utilised.
  • the first part 1 is referred to as a filter box. Fitted in this is a replaceable filter 10.
  • a filter hatch 6 which may be insulated against condensation, is undone, providing access to the filter.
  • a flexible and substantially airtight duct 3 is arranged in the lower edge of the filter box. The term substantially airtight means that the greater part of the air flow passes through the duct.
  • the material for the duct can also be selected so that a minor leakage is permitted, which cannot be deemed to affect the functioning of the duct, however.
  • the duct material be selected according to requirements, a flexible material preferably being chosen, that is to say a material such as textile, rubber, rubberised fabric, film, fibrous material or plastics, for example. It is also possible, however, to use material such as sheet metal, aluminium or other more rigid material, which may be combined and joined so as to provide a flexible whole.
  • a second part 2 Arranged at the other end of the flexible duct 3 is a second part 2, which may also be known to the person skilled in the art as an expeller.
  • expeller relates to a nozzle for blowing the air flow out and directing it, and which can be varied according to requirements. Other variants with equivalent characteristics may be used, however.
  • the second part 2 is designed so that the incoming air flow is delivered at high velocity and is angled upwards behind a radiator 5.
  • a high velocity is important in order to prevent the cold air in wintertime "dropping" down below the radiator 5 (due to the high density of the air). If this should happen it results in cold draughts along the floor.
  • Another important effect achieved by a high velocity of the delivered air flow is that the air flow then also expels the indoor air. This means that warm indoor air mixes effectively with the cold outside air, which means that the temperature of the mixed air flow increases. This effect is particularly important in autumn and in spring when the temperature of the outside air may be low whilst the heating system is not in operation. During the heating period the air flow is naturally also heated by the hot radiator 5
  • the design of the air device makes it possible to adjust the height of the air device so that the outside air is at all times delivered to the lower edge of the radiator 5.
  • the duct 3 has an elongated cross-section.
  • the duct 3 can be cleaned or replaced with a new one.
  • the filter box 1 and the second part 2 can also be cleaned, for example, in a dishwasher, manually or by any other suitable method, so as to thereby clean the affected parts.
  • the first part 1, the filter box comprises a box, the front side of which has an opening 7 in order to permit installation and changing of filters.
  • the filter box 1 further more has a rear side which bears against a house wall which is provided with holes for the incoming air.
  • In the rear wall of the filter box 1 there are holes 13 for fitting the filter box 1 to the house wall.
  • the sealing strip prevents air from percolating out between the filter box 1 and the house wall.
  • the opening 8 at the rear of the filter box 1 is somewhat over-dimensioned, the opening 8 being extra wide and high, in order to make the filter box 1 easier to install and adjust to the holes made in the house wall. It is possible to open up a number of holes in the house wall and the holes are not restricted to a particular size. However, the holes must be accommodated within the boundary of the rear opening 8 of the filter box.
  • the filter hatch 6 for closing the front opening 7 of the filter box 1 is arranged at the front of the filter box 1. This means that the incoming air coming from the holes in the house wall is guided downwards towards the duct 3 and on to the second part 2.
  • the filter hatch 6 also allows the filter 10 to be replaced or cleaned, as required.
  • the filter box 1 is furthermore open at the bottom, where the duct 3 is intended to be fixed.
  • the opening at the bottom allows the incoming air to flow towards the duct 3 and onwards to the second part 2, which is fixed to the other end of the duct 3.
  • two of the longitudinal sides of the filter box 1 are preferably angled towards the front and rear side respectively of the filter box 1, which allows the duct 3 to be fixed to the filter box 1.
  • Two grooves with rails reinforcing the grooves are correspondingly formed on the duct 3.
  • the reinforced grooves of the duct 3 are bent backwards and pressed into the hooks formed by the backward angled parts 12 of the filter box 1.
  • the first opening of the duct 3 is fixed to the lower opening of the filter box 1 and the second part 2 is accordingly fixed to the second opening of the duct 3 in the same way, using the same technique with which the duct 3 and the filter box 1 are connected to one another. It is possible to vary the height of the duct 3, that is to say the distance between the filter box 1 and the second part 2, so that the overall height of the filter device according to the present invention is adjusted according to the varying radiator heights encountered. Certain heights of radiators 5 are more common than others, however, which means that a standard height of air device will suffice for most radiator heights. For special designs of radiators 5 it is consequently very easy to adapt the air device to the height of the radiator 5 by using a suitable height for the duct 3.
  • the ends of the duct 3 are respectively pulled or pushed towards the filter box or the second part 2.
  • the reinforced grooves are bent outwards making it possible to pull the duct 3 free from the filter box 1 and the second part 2.
  • the second part 2 has an opening 11 to the duct 3 and said backward angled parts 9 for fixing the second part 2 to the duct 3.
  • the second part 2 also comprises at least one opening 4, an expeller, which is angled in order to allow the air flow from the duct 3 to be discharged towards the radiator 5 away from the floor and upwards. In this way the air flow is guided for a longer distance along the radiator 5, so that it is heated to the desired temperature and assumes a reduced velocity when the air flow leaves the radiator upwards and out into the room in which the air device and the radiator 5 are located.
  • the second part 2 preferably comprises two or more openings 4, so as to be able to guide the air flow between the panels of radiators having double panels or triple panels. It is also possible to use collapsible expellers so as to be able to adjust the angles at which the air flow is guided and also to allow an opening 4 to be completely closed.
  • radiator 5 If the radiator 5 is to be removed because there is not space to make holes above the radiator 5:
  • the embodiment can be varied in different ways without departing from the idea of the invention. It is possible, for example, for the duct 3 and the second, lower part 2 to comprise one integral unit, preferably made from one and the same material.
