Description

86797 The present invention relates to an electric heater frame arrangement.

5 In the past, electric heater bodies have had the disadvantage that they have been made of a large number of separate sheet metal parts which are connected to each other during screws and / or by spot welding and / or riveting at various stages.

10 It should be noted that each acceptance of parts by spot welding and / or screw / rivet joints involves a separate step 1. costs, which are further increased by the need for interim storage and transport from one work station to another for different subassemblies.

The present invention overcomes the above drawback by providing an electric heater body arrangement which can be obtained quickly and in the least number of steps, the more detailed features of which appear from the following description of the invention and the claims.

The invention will now be described in more detail with reference to the accompanying figures, in which:

The side wall as well as the front wall of the sheath part 1 comprise a plurality of cooling line openings 8, the lower edges of which are located at a distance hg from the lower edge 7 or slightly higher. Both side walls 5 of the jacket part 1 as well as the front wall comprise, near their lower edge, a r-no curve 8-13, which acts e.g. as mounting perforations for the time clock and controller and as bushings for the drive shafts. Thus, the location of the time clock and the controller can be selected as needed for either side wall 1C or front wall.

Both side walls of the jacket part 1 further comprise (in the example shown 4 pcs / wall) the mold holes 14.

Figure 4 shows how the upper edge 15 of the mold hole 14 is cut so as to form a gap 16 between the inner surface of the side wall 6 and the inwardly extending constraint 17 with respect to the casing part 1. The sheath part 1 may further comprise (in the example shown a total of 6) mounting / guide holes 18 located near the rough edges of the side walls 6 ta-20.

In Fig. 1, the number 24 denotes mounting angles which are L-shaped in cross section. The depth-oriented flange part 29 is so long that the rear wall 22 frame arrangement, assembled, is at the necessary distance from the wall of the sauna to which the stove is fastened by means of fastening screws passing through the holes 27 and 28 of the flange parts 26. It can be seen from the figure that the hole 27 is preferably in the form of a "keyhole" to facilitate attachment in a manner known in the art.

The mounting angles 24 further comprise mounting / guide holes 18. The mounting angles 24 extend in height approximately the entire length of the folds 4, moreover they may be further provided with openings 32 in their flange portions 29 (only one shown in broken lines for example 29) to further facilitate cooling air circulation and .

An embodiment of the frame arrangement, shown exploded in Figure 1, comprises reinforcement angles 29 which act as a washer for the fastening screws 30 (Fig. 3) and '-'-: further act as a rear support for fastening the outer sheath 31 (Fig. 7). The reinforcement angles 29 extend in their height direction approximately the entire length of the folds 4 and are preferably provided with fastening / guide _.

The vertical rear surface 36 is provided with openings 37 for the circulation of cooling air (2 in the pre-3 application) and holes for the passage of current and control conductors. 38 and a capillary tube lead-through hole 39. The side edges of the rear surface 36 are provided with forwardly extending folds 40, and the lower edge of the rear surface 3610 is further provided with a forwardly extending fold 41. The upper surface of the upper bottom 33 of the junction box is provided with holes 42, 43 the attachment of the heating resistors (in Figure 1 the perforations 42, 43 are provided for three separate resistors). As shown in Fig. 1, the upper surface of the upper bottom of the junction box may be provided with a rigidity-increasing netting press 44 which extends, e.g., slightly higher than said upper surface of the upper bottom. The upper sole 33 extends in the height direction approximately by notch-20 en h ^.

In Figure 1, the base profile of the stone space is indicated by the number 45 (one of the four shown in this, shown embodiment). It has a downwardly open U-shaped cross-section in its main shape (see also Fig. 6) 25 and comprises downwardly bent tongues 46 in its end portions 46. As can be clearly seen in Fig. 6, the web portion 47 of the profile is provided with a lower part 48 along its length. the down-stroke acts as a basin for storing 48 steam water, whereby the stove can humidify the sauna air even between the steam beats as the steam water gradually evaporates. from the pool. This provides a pleasant humidity throughout the sauna.
