RADIATOR RECEIVABLE IN A WALL RECESS Filed NOV. 7, 1958 u 8 E 9 n u U A u M In INVENTOR THOM LAGE HENNINGSSON United States Patent F Claims priority, application Sweden Nov. 12, 1957 1 Claim. (Cl. 257-136) The present invention refers to a radiator having a solid front plate and a rear plate which is receivable in a Wall recess, the front plate facing the edge parts of the wall recess and being provided with an opening for the circulation of hot air.
Known radiators of the above-mentioned type have many disadvantages, for example the need for connecting the radiator at its upper part to a supply pipe and at its bottom part to a return pipe, which involves the inconvenience that the supply pipe must be drawn to one of the upper edges of the radiator. Another disadvantage consists in that the space behind the radiator is difficult to reach so that dust will gather at the rear side and Will be removable only with difliculty. A further disadvantage consists in that the fine adjustment of the radiator is inconvenient. It is of course easy to turn off a radiator by means of its valve or to open the valve completely, but it is difficult to throttle the valve in such a manner that the radiator emits a required smaller heat quantity, owing to the fact that the radiator has a certain heat inertia so that the heat regulation effected by the valve will be perceived only after some time.
These disadvantages are eliminated by the invention, with a simultaneous reduction in manufacturing cost, by a construction in which a hot-water pipe passes through the bottom part of a radiator and is provided near its inlet end with a stream distributor acting as an injector, the pipe for this purpose being formed with an opening from which a stream-deflecting member extends slopingly into the pipe. Moreover, the pipe is provided near its outlet end with a further similar stream deflecting member functioning as an aspirator, the two stream-deflecting members being arranged in such a manner that the water entering the radiator is divided into a first part which passes through the interior of the radiator behind the front plate and a second part which passes through the middle portion of the pipe between the stream-distributing members; the front plate is preferably provided with an adjustable register for controlling the circulation of hot air behind the rear wall of the radiator.
The invention is described in detail in connection with the accompanying drawing which shows an embodiment of the invention as an example. FIG. 1 shows a radiator of the invention in front view. FIG. 2 is a section of the radiator of FIG. 1 along the line IIII.
The radiator shown in the drawing comprises a front plate of rectangular form which covers a recess 12 in a wall. To the lower edge 14 of the front plate 10 there is fastened by welding a heat-conducting pipe 16, extending from an inlet pipe 40 straight towards an outlet pipe 42 aligned with pipe 40. Behind the front plate 10 is placed a rear plate 18 parallel to the front plate. The upper edge 20 of the rear plate is fastened by welding to the front plate 10 at a certain distance from the upper edge of the latter. Both the side edges 22, 24 of the rear plate are fastened in the same manner to the front plate, the lower edge 26 being welded to the pipe 16. In order to insure a sufficient rigidity of both plates 10 and 18, they are likewise connected to each other by means of round depressions 28 pressed into the rear plate which is fastened to the front plate 10 at these depressions by spot welding. The two plates 10 and 18 together with the pipe 16 form a chamber which communicates with the pipe and, at its upper part, is provided with a safety valve 29. This chamber is traversed by hot water from a boiler (not shown), the pipe 16 being provided for this purpose with two lateral openings 30', 32'. These openings are produced by slitting the pipe near its ends to form tongues 30 and 32 which are then depressed towards the axis of the pipe into a sloping position pointing generally towards the center of the radiator. The tongues 30, 32 thus form stream-dividing members which divide the water quantity passing through the radiator into a first part which flows through the opening 30 into the container 10, 18 and a second part which passes below the stream dividing members 30, 32 through the middle portion of the pipe 16. The stream-dividing members 30, 32 act thus as an injector and an aspirator respectively. Both ends of the pipe 16 are provided with packing sleeves 34, 36 in which annular gaskets 38 of elastic material such as rubber or plastic are placed in order to seal the junctions of pipe 16 with inlet pipe 40 and outlet pipe 42 against the atmosphere. This mode of connection affords easy and inexpensive assembly and insures that the heat expansion of the radiator and of the associated conduits will not cause undue mechanical stress in the pipes. Besides, this connection constitutes a pivotable coupling.
At its upper part the front plate 10 is provided with a number of holes 44 behind which a bar formed as a flat strip 46 is slidably arranged. The strip 46 is pro vided with holes 48 corresponding in size, number and spacing to the holes 44 in the plate 10. The strip 46 can be actuated by means of a knob 50 which is connected with this strip through a slot 52 in the front plate 10. When the strip 46 is moved to the right by means of the knob 50, the holes 44 will be opened so that the heated air rises between the rear plate 18 and the recess wall can escape through the holes 44 and 48. By sliding the strip 46 to the left, the holes 44 can be closed so that any escape of hot air will be prevented and the heat emission of the radiator is diminished. This arrangement makes it possible to reduce the radiator output to about 20 or 30% of its maximum, as established by practical tests, without any control of the water flow.
The opening formed by the pipe 16 and the lower edge of the wall recess 12 suitably is covered by a base panel 52 in the form of a ledge provided with a slot-shaped opening 56.
In order further to increase the heat transfer from the rear plate 18 to the air rising in the space between this plate and the wall, there is disposed in that space a corrugated plate 58 abutting with its vertical round edges or ridges against the rear plate 18 and the recess wall, the elasticity of the corrugated plate enabling a compensation of irregularities in the distance between the rear plate 18 and the wall. The corrugated plate 58 can either be fastened to the rear plate 18 or loosely abut against the same, the plate resting on a support 59 mounted on the wall.
The entire radiator is tiltable downwards by tipping it about the inlet and outlet pipes 40, 42. For this purpose the central part of the base panel 54, located before the radiator and separated from the rest of the panel by cuts 60, 62 is designed as a downwardly tiltable leaf as illustrated in dot-dash lines in FIG. 2. The upper edge part of the radiator is detachably fastened on the wall by means of, for example, one or more screws. The rear side of the radiator thus can easily be freed of dust which as gathered thereon.
' What I claim is:
