Definitions
- the present invention relates to a convector intended to reduce the fall of cold air in front of a window or the like, and which convector preferably is designed as a window sill or a part thereof, heated by at least one heating element, wherein the convector is provided with at least one surface stretching along and through the same, said surface being designed to guide an air stream directed towards the window.
- the object of the present invention is to eliminate said disadvantages and to provide a heating device which is cheap and simple, and which can add enough heating power to a room in an efficient way.
- a further object is to provide a heating device which requires very little space and does not make the fur ⁇ ituring of the room more difficult, and which counteracts the so called fall of cold air from windows.
- This is according to the invention provided by arrranging the element/ elements in direct contact with the guiding surface, which is made of a heat conducting material, and by that the convector substantially in parallel to the guiding surface is provided with a heat insulation at least on one side.
- Figure 1 shows a diagram that describes how the need of heat in a room is covered.
- Figure 2 shows in a inclined upper view a heating device formed as a window sill according to the invention.

- Figure 6 shows a heating device in a view from the short side.
- Figure 7 shows in a cross section a part of a heating window- sill.
- Figure 8 shows further a window-sill provided with a channej .. . in which a heat emitter is arranged.
- Figure 9 and 10 show window-sills in different places at windows according to the invention.
- Figure 11 shows an alternative device for heating placed behind a cable pit at a window.
- Figure 12 shows a horizontal cross section through the heating device according to figure 11.
- Figure 14 is a cross section through the line XIV-XIV in figure 13.
- FIG 2 is shown an embodiment of a window-sill 1 with a heating element according to the invention.
- At least two brackets 2 are fixed on the wall 3 and are provided with mounting devices 4, here formed as a strip, for arresting of the window sill 1.
- the window sill 1 is provided with a groove 5 in which the edge 4 engages.
- the window sill is made of a heat insulation material such as perstorp, plastic, wood or the like and can for example be pressed or moulded.
- the window sill 1 is provided with a metal plate 6, for example of aluminium, which serves as a heating surface/transmitting surface, for a preferably electrical heating element which is 7 positioned thereon.
- the heating element 7 is preferably a so called foil element, a tube element or the like.
- a foil element is often very thin and totally encapsulated, and normally built up in a laminate of one or more insulating materials and one or more metallic conductive materials.
- insulating materials polyester, silicon rubber or mica ⁇ ite can be used, and the conductive material can be rustless steel, kanthal or another resistant alloy.
- An important advantage with foil-elements is that the heat is uniformly distributed over a ⁇ large surface. They are also flexible, thin and easy to apply.
- Tube elements mainly consist of a threadlike resistor encapsulated in an electrically insulating tube. If tube elements are used in the window sill, these can be mounted either in the sill 1 or in special grooves arranged in a metal plate, positioned under the sill 1.
- the board is preferably mounted with the side where the hot air streams out close to a wall or a window. In the case with a window the advantageous effect is provided, that the cold air stream, directed downwards from the window is eliminated or couneracted.
- FIG 3 an embodiment of a heating device formed as a window-sill, which mainly consisits of a metal profile 9 which forms two spaces 10,11.
- the first space is an air channel 10 between the front and back side of the window-sill.
- Air holes 12 are made along the long sides of the metal profile on the front side, on the back side, lower side and upper side, which causes the air to stream inside the profile from the front side of the window-sill to the back side thereof when the heating element is connected.
- an insulat ng or stabilizing material 13 is pressed in together with an heat transmitter 14, for example a foil element.
- the window sill is preferably mounted on a wall at a window by means of brackets (not shown) and the element is connected to the line voltage by cables (not s own) .
- FIG 4 is shown further an alternative heat window sill, which consists of two parts, one solid lower part and one upper part made of plate.
- the lower part is preferably extruded and has threadlike heating elements 15 which are encapsulated by an insulating material.
- an air channel is arranged where the air is heated from beneath and is brought to stream from the front edge of the heat window sill towards the back edge.
- Figure 5 shows the window board form one long side, whereby a control panel comprising thermostate and regulating devices are shown.
- FIG 6 is shown further an embodiment of the heating window sill according to the invention, where a sheet element 17 is positioned between two plates which are bent in their front and back edges.
- This window board is very thin and easy to place and it radiates heat in all directions.
- FIG 7 a cross section of a part of a heating window sill, wherein the upper surface 18 can be made of wood, a laminate or a plate, and which surface is substantially cold.
- the upper layer Under this upper layer a thick insulating layer 19 is disposed to stop heat from passing upwards to the upper surface of the window board.
- a heating element 20, for example formed by a foil element, and thereunder aluminium plate 21 is positioned as a protection for the foil r element. The aluminium plate conducts the heat from the sheet element to the surrounding air and is thus quite hot.
- Figure 8 shows a further example of how a window-sill can be built up and it is substantially made of three parts, one upper and one lower insulating part 22 and 23, between them is an air channel, and in this channel a heating unit is arranged, mainly consisting of an aluminium plate 24 and a foil element 25 mounted thereon. The parts are joined together by screws 27 and/or distance elements 28.
- a protector 26 can be positioned, which stops objects from falling into the channel and guides the air from the channel, for example towards a window.
- the upper surface of the window-sill is hard in order to make cleaning easier .
- FIG. 9 shows two possible positions for a window-sill according to the invention.
- Figure 9 shows that it is possible to place a window sill directly onto the window frame if the window is placed near the facade.
- the window-sill has been mounted on a bracket 2 because the window is located near the inside of the wall.
- FIG 11 shows a further embodiment of a heating device 29 according to the invention.
- a heating device 29 it is vertically placed behind a cable pit 30 or the like, and in figure 12 in a cross section through the heating device is shown that two insulating layers 31 ,32 with distance means form air channels in which an aluminium plate 3 with a foil element 34 fixed thereon is placed.
- the heating element can of cource also be tube elements or the like. The air streams in this case through the heating device from beneath and is heated when it is passing the element 34 and the plate 33.
- the electric connection between the incoming cable and the foil element is for example provided by means of a connection terminal board 35.
- an embodiment of the convector according to the invention comprises a beam 36 which is made by light metal, which extends centrally through the convector and in a cross section is I-shaped, the beam isin its cross flanges provided with grooves 37 for recieving S-Vid arresting two profiles 38, 39, mainly C-f ⁇ rmed, which profiles together form the cover of the convector, and grooves 40 for recieving brackets 41 which supports the convector.
- a passage 42 for a tube-formed heating element 43 which is in heat-conductive contact with the I-beam 36.
- the electrical connection between in-coming cable and the heating element is provided by for example a connection terminal board 35 which is brought against a holder 44, which is fixed onto the I-beam 36.
- a number of feed-through openings 45 are made, which are formed by inwards bent tongues 46.
- the air will thereby stream through the convector from beneath and is heated when i ⁇ .is passing the I-beam 36, which is in heat-conductive contact with the heating element 43.
- the tongues 46 are also arranged to the insulations 47, 48 which are placed against the insides of the C-profiles.
- the cover formed by the C-profiles 38, 39, is at the ends closed by end caps 49, 50, which are fixed to the I-beam 36.
