Definitions

  • the present invention relates to an air room ventilator comprising an air inlet for leading replacement air into an air channel of the ventilator, an air outlet for leading the air to a room, and a housing.
  • Air ventilators are known which can be used to input replacement air from outside to a room to improve the air quality in the room.
  • Such air ventilators can usually be installed on the wall which requires that a hole has to be made through the wall, wherein the air ventilator is installed in or on the hole.
  • Walls of a building can be made e.g. of concrete or tiles which are hard materials. Hence, it is not easy to make holes through such walls.
  • air ventilators which can be installed above a window, either in the frame of the window or in a narrow space just above the frame of the window.
  • These kind of air ventilators may have an internal channel for guiding the incoming air to a certain direction when the air leaves the air ventilator. The direction is e.g. partly upwards and partly sidewards from the window so that the air flow is not perpendicular to the plane of the window.
  • the space above the window frame is not always high enough to that this kind of slid-like air ventilator could be installed above the window frame.
  • the publication EP 0 204 864 discloses an air ventilator which is mounted inside a room, on a window frame.
  • the window frame has a hole via which air can flow from outside to the inlet of the air ventilator.
  • the air ventilator has an electric blower to improve air flow in the air ventilator. This kind of structure is very complicated and because the air ventilator has to be installed on the frame it sticks out from the window frame. Further, a hole has to be made through the window frame to form an air passage.
  • An aim of the present invention is to provide an air ventilator which can be installed beside a door frame or a window frame. This makes it usually easier to find a proper place for the installation of the air ventilator and usually no holes need to be made for the air ventilator.
  • the air ventilator of the present invention is primarily characterised in that the air ventilator is adapted to be installed in a slit beside a window frame or a door frame.
  • An advantageous embodiment of the present invention is characterised in that the air ventilator comprises an air flow regulating element.
  • the air ventilator comprises a channelling element which defines a wall of the air channel inside the air ventilator, and said channelling element is also adapted to lead water out from the air channel.
  • the air ventilator according to the present invention has advantages compared to air ventilators of prior art.
  • the air ventilator can be installed in the quite narrow slit between a side frame of a window or a door and the wall on which the window or door is to be installed. Therefore, no holes need to be bored through the wall or though the frame. Further, the position of the air ventilator is not very critical so the height at which the air ventilator can be installed can vary in different situations. It is also quite easy to stack two or more air ventilators i.e. one air ventilator can be installed on top of another air ventilator if e.g. the air supply capacity of one air ventilator is not enough for a room.
  • the air ventilator of the present invention with an air flow regulating element by which it is possible to change the amount of air which can flow through the air channel of the air ventilator.
  • the air ventilator 1 comprises a housing 2, which is formed of one or more parts.
  • the housing has side walls 2.1, 2.2, a lower end 2.3, an upper end 2.4, an inlet side wall 2.5, and an outlet side wall 2.6.
  • the inlet side wall 2.5 comprises an opening 2.5.1 which functions as an air inlet 3.1.
  • fresh air can enter the air ventilator through the opening 2.5.1.
  • the outlet side wall 2.6 has an opening 2.6.1 which functions as an air outlet 3.2 letting air flow out from the air ventilator into the room.
  • the air ventilator 1 has also one or more air channels 3 inside the housing 2.
  • the air channel is limited (defined) advantageously by the side walls 2.1, 2.2 and the channelling elements 4.1, 4.2. It is also possible that the upper end 2.3 and/or the lower end 2.4 of the casing form a part of the walls of the air channel 3.
  • the first channelling element 4.1 is positioned at the lower part of the housing 2 and the second channelling element 4.2 is positioned at the upper part of the housing.
  • the first channelling element 4.1 is advantageously curved at one side so that the air flow can be better directed upwards when the air leaves the air channel.
  • the second channelling element 4.2 can also be partly curved or straight.
  • the channelling elements 4.1, 4.2 can be made of e.g. a foamy material like foam plastic which may improve the attenuation of sounds inside the air ventilator. It is also possible that the channelling elements 4.1, 4.2 are made of a sheet which is bent to a form appropriate for the walls of the air channel (i.e. curved, straight). In Fig. 2 an advantageous embodiment of the channelling elements 4.1, 4.2 is shown but it is obvious that the form of the channelling elements can differ from that.
  • the air ventilator also comprises an air flow regulating element 5 which can be used to regulate the air flow inside the air channel 3.
  • the air regulating element 5 comprises a sheet 5.1 which can be rotated or tilted by the knob or other handle 5.2.
  • the cross sectional area of the air channel 3 changes. If the cross sectional area of the air channel 3 decreases, the air flow usually decreases and vice versa. Therefore, by using the air regulating element 5 the incoming air flow can be better adjusted to correspond the need at a time. For example, if air is taken out from a room by an air pump the air flow through the air ventilator 1 can be adjusted according to the suction force of the air pump at a time. It should be mentioned here that the adjustment of the airflow regulating element 5 can also be made by a different way from rotating or tilting.
  • Fig. 7a depicts some details of an example embodiment of the regulating element 5 and Fig. 7b shows an example of a hole into which one end of the regulating element 5 can be positioned.
  • the regulating element 5 comprises the sheet 5.1 having a facet 5.3 at one end and a handle 5.2 at another end.
  • the facet 5.3 is e.g. a planar, triangular part as shown in Fig. 7a, a planar, curved part, or has some other suitable form to keep the sheet 5.1 of the regulating element in the hole or recess 2.5.2 made to the inlet side wall 2.5 as shown in Fig. 7b.
  • the outlet side wall 2.6 comprises a hole 2.6.2 (round or square or rectangular) through which the handle 5.2 of the regulating element 5 can be installed.
  • a spring 5.4 or other resilient material between the outlet side wall 2.6 and the sheet 5.1. The purpose of the spring 5.4 can be seen from the following functional description.
  • the position of the sheet 5.1 of the regulating element 5 can be moved between two or more positions.
  • the sheet 5.1 is in a first position in which the sheet is in the direction of the air flow in the air channel 3.
  • the larger sides of the sheet 5.1 are substantially parallel to the air flow.
  • the facet 5.3 is positioned in the recess 2.5.2 so that the facet rest against the up most and lowermost corners of the recess 2.5.2 (the position is shown with the dotted line x in Fig. 7b).
  • the handle When the regulating element 5 should be changed to a second position, the handle is slightly pulled out from the outlet side wall 2.5 until the facet 5.3 does not rest against the corners of the recess 2.5.2, and then the handle 5.2 is rotated to a second position which in this embodiment means a rotation of 90 degrees. Then, the handle can be released and the spring 5.4 pushes the facet 5.3 against the recess 2.5.2. Now the facet 5.3 rests against the other two corners of the recess 2.5.2 (shown with the dotted line y in Fig. 7b). In the second position the sheet 5.1 of the regulating element 5 is substantially perpendicular to the air flow thus decreasing the free cross-sectional area of the air channel 3. This restricts the air flow in the air channel 3.
  • the air ventilator 1 especially the form of the recess 2.5.2, can be constructed in such a way that more than two different positions for the sheet 5.1 are selectable. It is also obvious that other structures can be used for the regulating element 5 and for the adjustment of the regulating element 5.
  • the air ventilator 1 of the present invention can also comprise one or more filters 6 for filtering small particles out from the incoming air.
  • the filter 6 can be attached e.g. on the side wall(s) 2.1, 2.2 of the housing, near the air inlet or the air outlet.
  • the air ventilator comprises two different kind filters of which a first filter 6.1 is attached near the air inlet and the second filter 6.2 is attached near the air outlet.
  • the first filter 6.1 is advantageously designed for filtering larger particles than the second filter 6.2.
  • Many materials are known to an expert in the field for implementing the filters to achieve desired filtering properties. In this application it is not necessary to provide more details on filtering materials.
  • the filter 6 Due to the impurities in the outside air the filter 6 will become dirty when air flows through the filter 6. Therefore, it is necessary to change or clean the filter 6 from time to time. This can be done by removing either the inlet side wall 2.5 or the outlet side wall 2.6, depending on which of the side walls 2.5, 2.6 are arranged removable. It is also possible that both side walls 2.5, 2.6 are removable.
  • the opening 2.5.1 of the inlet side wall 2.5 and/or the opening 2.6.1 of the outlet side wall 2.6 can comprise one or more holes in the side wall 2.5, 2.6.
  • both openings 2.5.1, 2.6.1 can be formed as a lattice having narrow, parallel slits through which air can flow.
  • the wall 7 of the wall has an opening for one or more doors 8 and/or windows 9.
  • the opening is a little bit larger than the frame 8.1 of the door(s) and, respectively, the frame 9.1 of the window(s). Therefore, there will be a narrow slit around the window frame 9.1 and on both sides of the door frame as well as above the door frame.
  • the air ventilator 1 can usually be installed in any of the vertical slit i.e. on either side of the door frame 8.1 or the window frame 9.1.
  • the installation height of the air ventilator 1 can also be quite freely adjusted in the slit.
  • the incoming air may be rather cold wherein if fresh air enters the room near the ceiling the air has more time to become warmer before the air falls down in the room. This might have the effect that people in the room feel less draught compared to a situation in which the air ventilator 1 were installed near the floor of the room.
  • the behaviour of the incoming air can also be at least slightly affected by the air channel 3 of the air ventilator 1. If the air channel 3 is directed upwards near the outlet, the air flow is also directed upwards. To achieve this, especially the upper i.e. the second channelling element 4.2 is designed so that it gives the air flow the desired direction at the outlet 3.2 of the air ventilator 1.
  • the first channelling element 4.1 may also be curved to decrease the flow resistance of the air channel.
  • the first channelling element 4.1 can also have the effect that water, which may enter the air channel outside e.g. when it rains, or which may be due to humidity condensing on the walls of the air channel 3, can flow outside from the air ventilator 1.
  • Fig. 5 a cross-sectional view of the installation of the air ventilator 1 according to the present invention is depicted in a simplified manner. It can be seen that the air ventilator 1 is attached to the wall by some kind of attaching means (not shown) such as screws, adhesive, foam, rivets etc.
  • attaching means such as screws, adhesive, foam, rivets etc.
  • U-shaped beams 12 in the opening of the wall which are fixed to the wall 7. The beams are meant inter alia to fix the frames of the doors and the frames of the windows to the wall. If such U-shaped beams are used, it may be necessary to make a hole to the beam for the air ventilator 1, or the air ventilator 1 can be installed on the beam as shown in Fig. 5. It can also be seen from Fig.
  • the depth of the housing of the air ventilator 1 is advantageously the same or almost the same than the thickness of the wall 7.
  • the frame 8.1, 9.1 is narrower than the thickness of the wall 7, also the depth d of the air ventilator 1 can be smaller than the thickness of the wall 7.
  • the depth of the air ventilator 1 is preferably the same or almost the same than the thickness t of the frame 8.1, 9.1.
  • air ventilators 1 it may be necessary to install two or more air ventilators 1 for a room. This can be done, for example, in such a way that another air ventilator is installed on top of one air ventilator 1, or on both sides of the window 9 or the door 8, and/or one air ventilator 1 is installed beside a window 9 and another air ventilator is installed beside a door 8.
  • the air ventilator 1 of the present invention can be manufactured by using a sheet-like material like metal, plastics, etc. It is also possible to use some kind of moulds in the manufacturing process. As an example the so called injection moulding can be used to form the housing or parts of it of plastics.
  • the side walls 2.1, 2.2, the lower end 2.3, the upper end 2.4, the inlet side wall 2.5, and then outlet side wall 2.6 are cut from the sheet and bent at appropriate locations to achieve the desired structure. In some cases most of the walls can be made by bending one sheet which is first cut to a desired shape.
  • the inlet side wall 2.5 or the outlet side wall 2.6 should be made as a separate part, which can be fixed to the housing by screws, clips or by other kind of attaching means. It is also possible that the inlet side wall 2.5 and/or the outlet side wall 2.6 is two-part. Hence, one part can fixed to the housing while the other part is removable. The fixed part can then be made in such a manner that it gives more rigidity to the housing of the air ventilator 1.
  • FIG. 6 an example installation of the air ventilator 1 according to the present invention is depicted.
  • the air ventilator 1 is installed beside a window frame 8.1, in the slit 13.
  • the slit 13 and the air ventilator 1 are covered by a list 14 to make the appearance of the installation neat.
  • the list has an opening 14.1 at the location of the outlet 3.2 of the air ventilator 1.
  • the opening 14.1 can be covered with a lattice 14.2 having narrow slits to allow the flow of the incoming air from the air ventilator 1 to the room.
  • part of the outlet side wall 2.6 may remain visible when the air ventilator 1 has been installed beside a frame. Therefore, to make the outlook of the installation concise an additional element 10 can be installed below the air ventilator 1 as shown in Fig. 1.
  • the structure of the additional element 10 is substantially similar to the structure of the housing of the air ventilator except that the additional element does not have any air channels or openings for air passage. Those sides of the additional element 10 which remain visible when installed in the slit is uniform and preferably have similar outlook than the corresponding side of the air ventilator 1. Further, the thickness of the additional element 10 should be substantially the same than the thickness of the air ventilator 1.
  • the height of the additional element 10 is adjusted to be such that the total height of the additional element 10 and the air ventilator 1 substantially corresponds the height of the frame on which the air ventilator 1 and the additional element 10 will be installed.
  • the additional element 10 can also be manufactured by using a sheet-like material from which an appropriate part(s) is/are cut and bent to a desired shape.
  • the additional element 10 is formed e.g. as a rectangular housing inside of which can be filled with a filling material like foam etc.
  • the additional element 10 can also be used even if parts of the air ventilator were covered by a list 11 as shown in Fig. 6.
  • the list 11 also covers the additional element 10.
  • the purpose of the additional element 10 is to fill the remaining part of the slit between the frame 8.1, 9.1 and the wall 7 or the beam 12.
  • the housing of the air ventilator 1 as well as the optional additional element 10 can be painted to protect the housing against humidity, dirty air etc. and for giving the housing a desired outlook.
