Fireplace insert made of sheet steel BSBBnasasBansBisaiBBBBSsa

The innovation concerns a fireplace insert made of sheet steel according to the preamble of the main claim.

Such fireplace units are generally known according to DE-OS 2923 593, CH-PS 4o7 474, GB-PS 77o271.

In all of these known inserts, the loading openings are provided in a cross-sectional size which is practical the full opening size of the combustion chamber cross-section corresponds in this area.

With such a large cross-section, however, a disproportionate amount of air can enter the combustion chamber and thus also directly get into the chimney.

In addition, the fact that the Einaatz through the large Loading opening practically no heat-emitting devices Has more front surface, apart from the radiation from the hearth, no front surface heat radiation occurs

• ·

For this reason, it has already been proposed that opening panels be installed in the upper area of the loading opening to be arranged to reduce the disproportionately large air supply. To also for a certain To ensure front surface radiation, one has to use the water-bearing Front surface areas widened to the side in order to form larger radiation areas. Ee lies on It is clear that in both cases it is relatively expensive Measures.

The innovation is therefore based on the task of creating a fireplace insert of the type mentioned at the beginning. to improve that on the one hand there can be no disproportionately high air supply and that on the other hand a certain amount of front surface radiation is guaranteed is.

This task is with a fireplace insert from the beginning mentioned type according to the invention solved by daa in the identifier dee Hauptanapruchea recorded. Advantageous further developments result from the UnteraneprOcheii.

Due to this novel design, which means neither an opening panel with corresponding attachment requirements requires additional measures to be more heat-effective Front surface enlargement, so by the simple Measure to reduce the size of the loading opening (reduction in relation to the actual cross-section of the combustion chamber in this area) the air supply conditions are adapted to improve, among other things then to a certain extent inevitably to an effective enlargement of the front surface It has to be taken into account that normally such non-radiation-effective front surfaces at all are not present in such fireplace inserts.

The novel fireplace insert is illustrated below with the aid of the graphic representation of an exemplary embodiment explained in more detail.

It show echematically 1 shows a front view of the insert; Fig. 2 is a section through the insert without Lings-

line H-II in Fig. 1 and Fig. 3 shows a section through the insert about l & nga

The cross-section 2 of the furnace 3, i.e. the cross-section The loading opening is in the immediate area 1 is indicated by dashed lines in FIG.

As can be seen from FIG. 1, this loading opening 1 is significantly reduced in size in relation to this cross section, with the lower edge k of the loading opening 1 being arranged at the level of the bottom surface 5 of the furnace 3.

This reduction in cross-section results in uiSrmeabatstrahlungawirkeame Areas (roughly hatched in FIG. 1) of the front surface 6 of the housing 7, daa with water-bearing Double-sided includes the combustion chamber 3 and the exhaust chamber 3 '.

The Fig. 2,3 correspond to the section lines II-II bzu. IXZ-III in Fig. 1, but not the frame 8 contains.

This frame 8 is on the front surface 6 of the housing 7 ex. arranged to run roughly along the dashed cross-sectional line Z of the furnace 3 (ex. welded), whereby, as can be seen from Fig. 2, 3,

the lateral frame surface 9 and the upper frame surface Io more or less distanced from the Rndern 11 of the loading opening 1 are attached.

lilia of FIG. 3 can be seen, while the lateral surfaces 9 i frame obliquely to the front surface 6 extend, that is arranged to converge to the combustion chamber 3.

In addition, all of the frame surfaces 9, Io are flanged 12, behind the complete Einaatzea depending on the type of installation, if necessary, a suitable facing can be arranged for the whole chimney.

The construction measures described lead, apart from the resulting technical effects, in addition to the optical effect of a large chimney opening, as is usually the case with known ones open chimneys is given, although the actual loading opening 1 is sometimes smaller.

The dash-dotted frame in Fig. 1 is intended to show the actual outer contours only in etbia clad housing 7 illustrate.
