Description

94171

This invention relates to a heating furnace arrangement for raising and maintaining the thermal space of rooms in buildings. With a slight change in the assembly of the parts of the heating furnace arrangement, it can be formed into a sauna heater.

Until now, metal-built fireplaces for heating rooms in buildings or fireplaces of this type have had the weakness of dissipating heat the most and mainly only when the fire is constantly burning. When the fire is extinguished, the metal structures give off their heat up quickly, the fireplace 1. the stove cools down and is no longer able to heat its placement (assuming, of course, that the mass of the metal structures is within some reasonable and reasonable limits so that the stove can be lifted). Maintaining a constant steady and pie-20 light fire would remedy the situation, but is often, especially when using solid fuel, an idea to be ruled out due to its practical inconvenience. Of course, by using a stove with a high heating power, it is possible to raise it yourself momentarily. The internal temperature is 25 so high that the room temperature cannot be lowered too low, e.g. within a day, when the fire is extinguished, but in such a procedure the disadvantage is, of course, that said high temperature is again too high, unpleasant. Variations in room temperature in intermittent heating with a stove are easily excessive.

Excessive variation of the room temperature 35 otherwise caused by intermittent heating is controlled by making the heat storage capacity of the fireplace or heating furnace large enough. Conventionally, this 94171 2 is obtained, for example, in shell or tile kilns by masonry them by hand from a sufficiently large number of bricks on site. Among the industrially manufactured products in which a high heat storage capacity is achieved, mention may be made, for example, of fireplaces made of soapstone or (light) concrete, which are assembled in their final location from parts which have been pre-shaped to fit each other at the factory. In the latter example, there are e.g. the following disadvantages: 10 As a general rule, masonry mortar is required in the assembly in any case to ensure the tightness and fire safety of the joints. The assembly thus still resembles masonry, being laborious and possibly unclean to its environment. Furthermore, in order for such fireplaces to remain intact year after year despite the effects of successive heating and cooling, they must be built too massive, i.e. they are not able to give off heat once after cooling 20 only after a long heating time. Excessive massiveness, of course, causes its own high demands on the foundations of the fireplace.

The weakness of hand-built or prefabricated fireplaces, which, once cooled, are ill-suited to a relatively rapid rise in room temperature, has been attempted to be improved by providing them with a separate hearth placed in the hearth of the fireplace. The function of the hearth just mentioned is to equip the fireplace with such a circulation of air that this air circulation immediately after lighting the fire in the fireplace begins to heat the air in the fireplace room. Thus, the heating effect of the fire when using a separate fireplace core is not exclusively related to raising the temperature of the fireplace, 35 so when the heating is started, the temperature of the space to be heated itself rises within a reasonable time - to the desired level. The solution just described is, of course: »H:« ir l i nt 3 94171 very expensive, because in addition to the foundations of a massive fireplace, the fireplace hearth is also mentioned.

A step in the right direction in the development of prefabricated fireplaces is represented by a type of fireplace in which the metal body of the fireplace is formed so that when assembling the fireplace, the fire bricks included in the firebox structure surrounding the firebox at the bottom and sides are placed in place. However, such a solution, in which said fire bricks are able to store some heat, has disadvantageous cost factors: the fire bricks included in the delivery package are not necessarily cheap, and the whole structural solution, which is formed solely for the 15 fireplaces in question, becomes expensive. At least the latter feature is not facilitated by the fact that there are as many different types of fireplaces on the market as possible, so that in a highly competitive environment, the production batch size will inevitably remain relatively small, which is still likely to increase manufacturing costs.

The above-mentioned disadvantages and shortcomings are remedied by the heating furnace arrangement according to the invention. This is achieved by providing the heating furnace arrangement according to the invention with the features which appear from the claims.

The heating furnace arrangement according to the invention enables the temperature of its placement space in a reasonable time, e.g.

· Lifting with solid fuel during one or two nested burns. At the same time, thermal energy is bound to the charging mass of the heating furnace arrangement, which for a rather long period of time, in this exemplary day, for example, is able to keep the temperature of its placement comfortable without maintaining the fire.

94171 4

The heating oven arrangement according to the invention can advantageously be used, in addition to raising and maintaining the temperature of its storage space, as a slurry which enables cooking operations.

5

The heating furnace arrangement according to the invention can advantageously be used as a fireplace, which in addition to heating allows the creation of an atmospheric factor in its operating space. The heating furnace arrangement according to the invention does not require any masonry operations during installation, and the installation itself does not require any special skills.

Since the heating furnace arrangement according to the invention does not include a heat storage mass installed in place in fixed masonry, the weight of the heating furnace arrangement for transport and installation remains low enough to make these operations easy to perform.

20

At the same time, the user of the heating furnace arrangement according to the invention does not necessarily have to buy the heat-storing masses available for the heating furnace arrangement, but can also obtain them in the shape and quality which is most advantageous to him.

The manufacturing costs of the heating furnace arrangement according to the invention can be reduced by the fact that with a slight change in the assembly of the parts, the heating furnace arrangement can be formed into a sauna heater.

Other advantages and features of the heating furnace system 55 listed above and in accordance with the invention will become apparent from the following detailed description of the invention.

In the different figures, corresponding parts are provided with the same reference numerals.

In Fig. 1, the operating part of the heating furnace arrangement according to the invention, e.g. The operating part 1 comprises in the middle 15 a combustion space 2, on both sides of which there are charge spaces 3 (see also Figures 2, 3 and 4). The combustions 2 comprise side walls 4 which, when continuing downwards, can approach each other at points 5 while approaching the bottom 6 of the combustion or combustion chamber 2. An opening 7 (indicated by dashed lines in Figure 3) is formed in the bottom 6 of the combustion chamber 20. see Figures 15-18). Below the base 6 (and of course below the grate 8) in Figure 1 there is an ascending front-facing open U-shaped ash box 9 extending between the firebox front plate m 10 and the firebox rear plate 11 in connection with these ends, of course the ash box 9 branches the upper edges join the base 6. For the ash box 9, an opening 12 is formed in the front plate 10, through which the ash can be pushed into place in a conventional manner; a trough 13 (the latter is not shown in Figures 1-4, but is shown, for example, in Figure 5), which trough 13 is most commonly of an upwardly open U-shape, even with its rear or stern part 35 open, without a vertical wall . The ash trough 13 is provided with a front wall 14 (see Fig. 5) which, when the trough 13 is in place, tightly closes the opening 94171 8 12, and the front wall 14 may be provided with a handle 15 bent from its material, for example. the steps at its lower edges may, as is known in the art, be provided with stiffeners supporting it during heating and cooling, which, however, are not shown in Figures 1 to 4 because of their conventionality.

The side walls 4 of the combustion chamber extend upwards, sending each other at points 16 to join at their upper edges to the lower edges of the substantially vertical side walls 18 of the firebox. It can be easily seen from Figures 1-4 that the wall portions 18, 16, 4, 5 and the base 6 (and even the plane surface 20) on both sides of the vertical plane of symmetry 19 can very well be formed by bending from one continuous plate, but said parts and the base 6 ( and the planar surface 20) can also be made considerably on the basis of the manufacturing costs, e.g. by welding 20 from suitably formed separate parts connected to each other.

In the embodiment shown in Figures 1-4, the upper edges 25 of the front panel 10, back panel 11 and firebox side walls 18 are substantially flush, the firebox 17 being closed above the plane 20 associated with the edges of the front panel 10, back panel 11 and side walls in the embodiment of Figures 1-4. Since the planar surface 20, while limiting the firebox 17 above it, heats strongly during the combustion event in the combustion chamber 2 and in the firing chamber 17 continuously, it can be advantageously used as a hob on which all heat-requiring cooking operations can be performed using various utensils. Thus, the heating oven arrangement according to the invention can be used as a slurry for cooking.

9 94171

Figure 2 clearly shows how flame guide plates 21 and 22 can be arranged in the firebox 17, preferably by attaching them close to the side walls 18, which ensure that the combustion of fuel 5 takes place efficiently in the combustion chamber 2 and firebox 17 without unnecessary heat energy entering the flue. The flame guide plates 21 and 22 thus improve the efficiency of the flame furnace arrangement according to the invention. It is very advantageous if the flame guide plates 21 and 22 are arranged as shown in Fig. 2 so that the flame guide plate 21 is located vertically in such a way that part of its lower area extends below the joining area of the side walls 18 and 16, creating openings or passages. for combustion / flue gases 23, while the flame guide plate 22 is preferably provided with a notch 24 at its rear / bottom edge, creating an opening or passageway for flames and combustion / flue gases 25. The flow directions indicated by arrows 23 and 25 cause a favorable vortex in addition to the main flow direction 26, whereby combustion is enhanced and the necessary heat transfer from the flames and combustion / flue gases to the walls of the combustion chamber 2 and the fire chamber 17 is ensured. As shown in Fig. 2, it is furthermore advantageous to place the guide plates 21 and 25 22 in an oblique position so that any ash and / or soot which settles on the plates can fall back to the combustion chamber 2 by gravity. This creates a self-cleaning effect.

Figures 1-4 show how both the planar surface 20 and the back plate 11 are provided with a flue gas opening 27, 28, either of which is selected for use as a flue gas outlet 29 depending on the installation and connection possibility of the flue gas flue. The flue gas opening 35 which is not in use is covered with a cover plate 30 which is fixed in place, e.g. by screws 31 (see Figures 11 and / 22), while the flue gas opening which is in use is secured, e.g. by screws 32, in place with screws 32. with a connecting piece 33, which may comprise, for example, a piece of annular connecting pipe 34 to which the flue gas flue can be easily connected (see Figures 20 and 21).

We have discussed above a planar surface 20 which is connected at its edges to the upper edges of the parts 18, 10, 11. This just mentioned arrangement can also be considered in this context to include a modification of a planar surface 20 made of, for example, cast iron, machined flat on its upper surface and provided on its lower surface with a rib extending into the firebox 17, which acts as a large heat receiving surface and can be tightly mounted, e.g. that, for example, a seal can be arranged between the edge parts of the parts 18, 10, 11 15, or the surfaces of the edge areas of the parts 18, 10, 11, the fastening / support plates arranged in the parts 18, 10, 11 and then the edge parts of the planar surface 20, for example, in terms of heat resistance, correspond to the properties of the asbestos tape 20.

It can be seen from Figures 1-4 that the operating part 1 comprises, on both sides, vertically extending profiles of cross-section in the form of 0. 35; The lower ends 25, which in the embodiment shown in Figures 1 and 4 in the example extend slightly lower than the lower edges of the front plate 10 and the back plate 11 with a stiffening fold 36, may be provided with base plates 37 through which the heating furnace arrangement rests on its placement base and distributes the weight of the arrangement . The longest, middle sides of the section across the C-profiles 35 form the vertical side sides 38 of the operating part 1, while the shorter sides 35 39 and 40 of the C-profile associated with the side sides 38 form extensions of the front and rear plates 10, 11 acting as part of the walls 3 and expanding the storage space. in an appropriate way. The marginal small folds 41 of the C-profiles 35 act as stiffeners in the application example shown in Figures 1-4.

By providing the arrangement according to the invention with side edges C-profiles 35, the sides 39, 40 of which form the extensions of the front and rear plates 10, 11 and the middle sides of the side parts 38 of the operating part 1, it is provided that the G-profile material is not in direct contact with puncture "there is no risk of burns, it may be thinner than, for example, the material of parts 20, 18, 16, 4, 5, 6 and 10, 11. Of course, if desired, the front and rear plates 10, 11 can be extended sideways to such an extent that they partially or completely replace the walls 39, 40 of the C-profiles 35, whereby the remaining 15 parts of the C-profiles can be replaced by U-profiles or straight plates (last said forming lateral sides 38). On the other hand, the C-profiles 35 can also be replaced by U-profiles (folds 41 are omitted, see application example in Fig. 8), or if desired 20 the area of the side sides 38 can be provided with stiffening profiling or additional stiffening folds corresponding to folds 41, in the latter case C -profiles 35 as a whole would consist of more than one; 25 parts. Furthermore, although the continuation of the C-profiles 35 below the folds 36 of the front and rear plates 10, 11 (the latter of which are by no means necessary when using a thick plate) naturally leaves a free gap suitable for airflow between the lower edge folds 30 36 and the placement base. not necessary. With the C-profiles 35 extending only to the level of the lower edges 36, in this case the non-resulting slits can be replaced by openings formed in the front / rear plate 10, 11 and / or in the walls 38, 39, 40 35, finally the front and rear wall walls 10, 11 and C- the profiles 35 can also be replaced by a structural arrangement in which, as deliberately, 94171 12 a uniform casing plate of the functional part replaces the walls 10, 11, 58, 39, 40, the casing plate being formed e.g. from its corner areas by welding together joined rectangular plate sections or corner folds and the plate portion (s) joined together by vertical seam (s).

The use of C-profiles 55 as part of the structure of the operating part 1 naturally allows, if desired, also an application of the structure of the operating part 1 in which the C-profiles 55 are connected, e.g. by welding, to the side edges of the front and rear plates 10, 11 from the edges of the outermost folds 41. -spaces 5 can, if desired, be increased in the depth-15 direction of the heating furnace arrangement.

Figures 1-4 (and particularly clearly Figures 5, 6, 8) also show fasteners 42, which are formed by way of example of a U-shaped bent body piece 20 and which are fastened (e.g. by welding) from the edges of their U-shaped branches to the operating part 1. on the outer surface in the necessary places. The fasteners 42 fasten the outer jacket plates of the heating furnace arrangement according to the invention at the required distance from the operating part 1 itself, so that the outer jacket plates and thus the outer surface of the heating furnace arrangement remain sufficiently cool and non-hazardous during use despite heating of the operating part surfaces. In order also for the fasteners 42 to function as little as possible as thermal bridges 30 from the operating part 1 to the outer jacket plates, it is necessary to brochure: ·. In this embodiment, the actual attachment point areas of the fasteners 42 themselves are partially punched out of their location with a punch to create a gap 43 for further air flow to be cooled in the immediate vicinity of the attachment point (see Fig. 8). Of course, the fasteners 42 can be modified with the most numerous known in the art

Il lii l Ml. I I I UI I

13 94171, and the shape of the fasteners shown here is nothing more than an exemplary solution.

In the application example shown in Figures 1-4 (see

5 also Figures 5 and 6) the filling opening 44 of the combustion chamber 2 formed in the front plate 10 is provided with a circumferential stiffener 45 which helps to maintain the shape of its edge, which in this example has a profile bent in an L-shape in cross section.

Figures 5 and 6 show in more detail an application example of the combustion chamber door of the heating furnace arrangement according to the invention. In this example, the hatch is equipped with a glass 46 that is resistant to thermal stresses and mechanical effects as necessary. Using glass 46 as part of the hatch allows flames and combustion to be seen through the atmosphere creatively, which is important when using a furnace arrangement, but also ensures fire safety by preventing sparks from escaping. In the embodiment shown in Figures 5 and 6, the structure of the hatch further comprises a frame 47 to which an additional frame 48 is attached, which, when the hatch is closed, rests on the outer surface of the stiffener 45. Between the frame 47 and the additional frame 48, a loose space is received for receiving the glass 46, so that when the door deforms due to thermal stresses, such deformation cannot break the glass. The glass 46 is compressed toward the additional frame 48 by a plurality of spring members 49, sealing the door and centering the glass. At the top of the door, the frame 47 is left open (marked with reference numeral 50 in Figure 5), which allows the glass 46 to be installed and, if necessary, replaced or replaced.

As is known from the oven doors and as shown in Fig. 6, e.g. the upper hinge 51 may comprise an elongate hole for the hinge pin 52 so that the elongate hole allows the side of the door further away from the hinge pin 52 to be raised and lowered to the stiffener or frame 45. a corresponding recess in the tongue 54 attached to the additional frame 48 may be attached to the attached pin 53. Naturally, the door structure si-5 also includes a handle 55.

The above-described structure of the combustion chamber filling hatch is only exemplary, and a myriad of hatch solutions are already known which can of course be used and applied in connection with the heating furnace arrangement according to the present invention. One desirable feature of the hatch is (in the case of a one-piece hatch), e.g., that its manual handling (i.e., opening from the right or left edge) can still be freely selected and changed at the disposal site. An example of the implementation of such a feature is presented e.g. in Finnish advertisement publication No. 77571.

In such cases of use of the heating furnace arrangement 20 according to the invention, e.g. when using the arrangement as a sauna heater or a stove with only cooking facilities, where no door transparency is required or the glass door (s) are considered too expensive by the user, the door (s) can be replaced simply; 25 with a more direct structure. An example of this is shown in Figures 7 and 8. The door now simply consists of a plate 56 with edge folds with hinges 51, handles 55 and locking tongues 54. Figures 7 and 8 show the door with a further 30 shields 57 which prevent glowing balls from coming into direct contact with the outside.

In the embodiment of Figures 7 and 8, the stiffener or frame 45 flanking the combustion chamber filling opening is further shown to be displaced some distance away from the front plate 10, allowing the hatch to remain cooler during the combustion process, and also the danger of the frame 45 being deformed. ii Hl 1 15 94171 don distortion decreases. However, it is a desirable feature that the closed hatch of Figures 7, 8 be directly interchangeable with the glass hatch of Figures 5, 6, which is of course possible by choosing the dimensions of the parts to be operated and in contact to be equal.

In the embodiment of the operating part 1 of the heating furnace arrangement according to the invention shown in Figures 1-4, which is intended for fireplace and stove use with cooking facilities, the base plates 58 of the storage space 3 are shown extending outwards from the lower corner areas of the ash box 9 and obliquely upwards towards the side walls. 38 to steps 15 of the latter inner surfaces. The base plates 58 may be provided with suitable openings or notches 59 (see Figures 1 and 2) which allow air to pass through if necessary (indicated by arrows 60 in Figure 1). The base plates 58 are placed in an oblique position 20 as shown in Figures 1 and 4 because it can be thought that the oblique e.g. facilitates the filling of the charge spaces 3 as tightly as possible with heat-accumulating bodies such as stones. Within the scope of the invention, the base plates 58 can of course also be located e.g. in a horizontal position and at a different height than shown in Figures 1 and 4, so that the base plates 58, when lower, form one unitary base plate extending from the inner surface 38 of the second side 38 to the opposite side 38 . In the latter case, the volume of the charging spaces 3 and thus the number of suitable heat-storing pieces can be maximized. If, on the other hand, the base plates 58 are placed higher than in the position shown in Figs. 1 and 4, the space-35 of the charging spaces 3 and thus the maximum heat-storage capacity of the heat-storing bodies contained therein decreases. On the other hand, when more 94171 16, e.g. from the outer surface of the wall parts 5 of the combustion chamber 2, come into contact with external air currents, the heating effect of the heating furnace arrangement during its maintenance of fire is enhanced.

5

To summarize the above considerations regarding the exact location of the base plates 58 and its effect on the size of the charge compartments 3, for example: Once the room volume 10 in which the heating furnace arrangement is designed to be selected is selected, the size of the charge compartments 3 is selected so that the heat storage capacity at a comfortable level of the room volume temperature for a planned period of time, e.g. one to 15 hours after the heating period and so that during the heating period itself the room volume temperature does not rise too high. The fulfillment of the above-mentioned conditions for the size of the charge spaces 3 (and thus also for the exact placement of the base plates 58) is still influenced by the chosen dimensions of section 20 (height x width x depth), which can and undoubtedly be influenced by purely visual and design aspects of the final product. that the efficiency of the heating furnace arrangement is not compromised 1 '25 both in the use of fireplaces and stoves and in the use of sauna heaters (features and aspects related to the latter will be discussed later).

Figures 5 and 6 show an embodiment of the outer jacket plates (see also Figures 9-12) to be connected outwards to the furnace arrangement (see also Figures 9-12) and their attachment. Since the use of outer casing plates in connection with various heating furnaces and heaters is a well-known and conventional technique, the detailed embodiment of the outer casing sheets will not be considered in more detail in this context. It is noted only that in the application example shown in Figures 5, 6 and 9-12, the cat outer sheath plates consist essentially of four parts: two mutually symmetrical side sheath plates 61, a rear sheath plate 62 and a front sheath plate 63. and further plates can be arranged between the operating part 1 (marked in part and by way of example in broken lines the plates 64, 65 shown in Figs. 9 and 12), which can be made, for example, of an aluminum plate highly reflective of heat radiation.

However, it is necessary to consider some of the functional features or requirements of the outer jacket plates which are specific to the heating furnace arrangement according to the invention. Since it is desired that the heating furnace arrangement heat up its location during the heating period in a situation similar to the use of the stove and / or fireplace 15, the vertical slots 13 between the front jacket plate 63 and the rear jacket plate 62 and the front plate 10 and the back plate 11 are also provided at their upper end. and 14), which 20 may be provided with a perforation 67 which, in a controlled manner, allows heated air to pass through in its undercut. In addition, of course, during the heating cycle, the planar surface 20 transfers heat directly to the placement space of the heating furnace arrangement.

25

On the other hand, since the heat storage mass arranged in the charge compartments 3 is desired to transfer its heat to the location of the heating furnace arrangement relatively evenly and slowly, a direct alternating air flow past and along the walls of the charge compartments 3 must be prevented sufficiently effectively.

B

ti. The flow through the fire and fire compartment at the end of the heating period is, of course, prevented by closing the smoke damper included in the flue, but e.g. the air flow through the space between the walls 38, 39, 40 and the outer envelope plates must also be prevented sufficiently. si well. In the embodiment shown in Figures 5 and 6, a gap flow (indicated by arrow 70 in Figure 6) can be generated, for example, through the intermediate space 69 between the front plate 10 and the end edge of the sheath plate 61 near the front plate or fold 68 68, but this can also be effectively prevented e.g. in the manner shown in Fig. 8. In this example, the edge or fold 68 of the sheath plate 61 closest to the front plate 10 or side 39 is brought as close to the surface of the front plate 10 or side 39 as possible to eliminate slit flow, but the edge or fold 68 is provided with bumps 71 at a suitable distance from each other, e.g. which prevent the edge or fold 68 from continuing to contact the wall 10 or the side 39, which would otherwise result in the formation of a thermal bridge that interferes with operation.

15

As shown in Figs. 9-14, the charging spaces 3 as well as the vertical spaces between the outer jacket plates and the outer surfaces of the operating part 1 are closed at their tops by two mutually symmetrical cover plates 72. The cover plates 72 close tightly to the plate edges. said vertical intermediate spaces from above. Of course, under the lid plates 72, at least at the storage spaces 3, e.g. glass or mineral wool insulation can be provided, which prevents the above-mentioned lid plate 72 from overheating, whereby the lid plates 72 can be used preferably as a receptacle for cooking, e.g.

30: ·. The arrangement shown with reference to Fig. 8 to prevent or minimize the crack flow and at the same time the occurrence of a thermal bridge (fold near the hot surface or edge 68 with protrusions 71) or the like can also be used in connection with edges near cover plates 72, as well as near front and end plates 66. the edges of the back plate 10, 11.

Il IM I llll I: l Hl I

19 94171. The closure plates 66 may further be provided with a sliding plate sliding against the surface containing the perforation 67, with a perforation approximately corresponding to the perforation 67, which can be moved to adjust the air flow through the perforation 67 or to close it completely.

In Fig. 12, the charging spaces 3 of the above-described embodiment are still shown in broken lines for clarity. When the heating furnace arrangement 10 according to the invention has been lifted into place and installed, the charging spaces 3 can be filled with heat-storing mass with the removable cover plates 72 removed. The heat-storing mass may simply consist of e.g. crushed stone blocks or pieces 74 (as shown in broken lines shown to the right in Figure 12) of suitable size, the quality of which is such that they are able to store a large amount of heat for themselves and are long-lasting and resistant to temperature changes. against the tendency of weathering or crumbling-20. Stones of this type are commonly used and available for use as sauna stove stones. There is nothing to prevent the purchaser and user of the heating furnace arrangement from collecting and placing in place as a storage mass the stones they find and are suitable, e.g., found in nature. There is also nothing to prevent him, if he so wishes, from masonry or masonry the heat-storing mass inside the charging spaces 3.

Figures 15-18 show an embodiment 101 of the operating part of the heating furnace-30 arrangement according to the invention, which is otherwise similar and consists of the same parts as the embodiment 1 shown in Figures 1-4, but now the parts forming the fire and firebox 2, 17 are fixed in height lower than the corresponding ones. in Figures 1-4.

35 Corresponding to the height calculation, of course, the combustion space filling opening formed in the front plate 10 - * 44 3a the ash box opening 12 and the flue gas opening 28 formed in the rear plate 11 have been reduced by the same amount. In the exemplary embodiment shown above, the bottom plates 58 of the storage space 3 'have been moved so high that the lower edge of the bottom plates 58 with notches 59 (the latter 5 now acting as excess water drainage holes) is at the junction of the combustion space wall parts 4, 16. Further, the walls 38 of the C-profiles 35 are now provided with openings 75 (shown in broken lines in Figure 16) which allow a strong air flow 10 indicated by arrows 76 to pass through. As shown in Figs. 19 to 22, the aforementioned cover portions 72 have now been omitted and replaced by a light profile 77 having a cross-section, e.g. L-shaped, circulating along the upper edge of the jacket plates 61, 62, 63.

It is just as described in the procedure is provided in Figure 22 by dashed lines yet to view a contingency reserve space 3 'which is just saunas characteristic 20 and the characteristic of the stone shaped and sized to permit the stones 74 (only the right side of the stones 74 is drawn visible to Figure 22) for laying therein and upon such that the firebox 17 can be completely covered on at least three sides with a sufficiently thick layer of stove stones 74 to provide good steam absorption capacity. A strong air flow 76 through the slots between the front and back plates 10, 11 or the folds 36 and the placement base (which can be replaced by perforation as mentioned above) and the openings 75 can now effectively heat the interior of the sauna, as the flow 76 can freely touch the walls 5, 4 of the combustion chamber 2 during combustion in the fire and fire compartments.

35 The openings 75 shown in Fig. 16 can be easily punched into the walls 38 with a punching tool, so that the punching takes place e.g. at the depth of the plate 38 and mainly along the circumference of the opening 75, but e.g. the insertion tool does not have a cutting edge at the parts in question), so that the "waste piece" of the opening 5 75, which has not yet come off, remains tightly in place. Said retention can be left permanent in the case of the application example shown in Figures 1-4 (the stationary "waste pieces" are denoted by the number 78 in Figure 1), and the pieces 78 mentioned in the application example-10 of Figures 15-18 are simply knocked out. In this way, if desired, the C-profiles 35 can be made completely identical in all applications, except that in the case of a stove, the "waste pieces" are knocked out and otherwise not. Of course, the procedure just described is not necessary, since perforating the openings 75 in the walls 38 in the case of the operating part 101 is in itself a very simple and inexpensive operation and does not pour out the cost savings otherwise provided by common parts suitable for different applications. Furthermore, in the embodiment 101 shown in Figs. 15-18, it is not necessary to use exactly the same and shaped shapes of the charge space 3 'base plates 58 as used in the charge space 3 embodiment shown in Figs. 1-4, but for both applications its own base plates 58 can be formed. , because these are insignificant in terms of cost, dimensions, raw materials and the work involved. Furthermore, the profile 77 surrounding the upper edge of the outer jacket plates shown in Figs. 19-22 is not a necessity if e.g. the upper edges of the outer jacket plates 30 are already provided with a stiffening and neat fold 79 (Figs. 5, 13 and 14), which also prevents dangerous sharp edges. presence of plate edge edges.

The previously described procedure of leaving the "waste piece" of the hole made with the insertion tool partially in place. By not cutting, the 94171 22 can also be advantageously used to provide the rear jacket plate 62 with a hole that may be needed by the flue connection. In Fig. 12, when the flue gas opening 28 is in use, the "waste piece" has been knocked out to provide the opening 80, while in Fig. 22, the "waste piece" 81 has been left in place.

Figures 23-25 show another embodiment forming the operating part 1 or 101 (the former is on the left side of the plane of symmetry 19 of Figure 23 and the latter on the right side 10). The application shown in Figures 23-25 differs from the previous ones in that the bottom 6 of the combustion chamber 2 is now formed flat between the wall parts 4, the bottom 2 being lined with a refractory brick or a special refractory mass formed by a volcanic liner 82. also some distance upwards along the walls of the combustion chamber. In this case, the arrangement will certainly withstand the 1. continuous long-term incineration of unusually heavy use.

However, it is possible to use a solution which is a combination or intermediate form of the application methods shown in Fig. 23 and Figs. 1-4, 15-18 in the bottom area of the combustion chamber 2 and in the area of connection to its walls 4.

Fig. 23 shows a modified embodiment for placing the base plates 83 of the charging space 3, 3 'in place. In the case of fireplace or fireplace use, with cooking facilities (left in Fig. 23), for example, support pieces 84 made of angular profile are fastened to the inner surface of the profile 35 in the height direction of the firebox base 6 or 30, on which the base plate 83 is simply placed without any additional fastening measures. Correspondingly, in the use of the sauna heater (Fig. 35 to 23 on the right), the support pieces 84 are attached to the profiles 35 higher so that when the base plate 83 is placed to rest on the support pieces 84, it settles at a height 23 94171 (base plate 83) such a strong air flow (which heats the interior of the sauna) past at least part of the combustion chamber wall 4 is possible. The support pieces 84 can be replaced by tabs formed in the walls of the profile 35 with a stabbing tool projecting inwards from the wall of the profile 35. The tabs or even the knobs replacing the operation of the tabs as well as the support pieces 84 may, if desired, always be formed in the walls of the profile 35 for both locations of the base plate 83 shown in Fig. 23, as the lower position tabs or the like can be bypassed.

The heating furnace arrangement according to the invention has been described above, which, with the fire and fire compartment in one position suitable for a) fireplace and h) fireplace use, and the c and sauna space in another position suitable for c) sauna stove use. In cooking stoves and fireplaces with cooking facilities, the heating furnace arrangement according to the invention includes a heat storage mass which dissipates heat evenly over a relatively long period of time to its storage room, the arrangement being such that the storage room temperature rises sufficiently rapidly even during the fire maintenance period. The possibility of equipping the combustion chamber filling opening of the arrangement with a transparent hatch tends to increase the comfort of the rear operation. In the use of a sauna heater, the arrangement acts as a continuously heated heater.

It is clear from the previous detailed description and it can be concluded that the method included in the arrangement according to the invention forming the functional part 1, 101 of the arrangement intended for both uses a) and h) and purpose c) only mainly by changing the attachment point brings significant savings in manufacturing costs.

94171 24

The savings to be achieved, taking into account the entire manufacturing process, are not greatly reduced by the fact that the filling opening 44 in the front plate 10 and the ash opening 12 and the flue opening 5 in the back plate 11 have to be located at a height corresponding to the attachment point (two different heights, instead change). Even the difference just mentioned can in principle be eliminated by choosing an altitude position of approximately 10 between the altitudes of the previously described uses a), b) and application c), but this is not desired, as it would easily have to compromise on the properties required for different uses.

15

The aforementioned saving effect on manufacturing costs is not the only and not necessarily the greatest. From the previous description of the heating furnace arrangement according to the invention, it is found that in the described application examples 20 the outer casing plates 61, 62, 63 of the arrangement also give the final appearance and shape and properties are substantially identical in their different uses a), b) and c). Of course, the identity also applies to possible additional insulation or reflective panels (e.g. 64, 65). Since durable consumables such as the one in question are required to be of high quality and flawless in their finishing sack, the arrangement of the outer sheath plates with all the work steps has a significant effect on the manufacturing cost. When the outer 30 sheath plate system remains constant from product to product, savings are automatically achieved.

The described heating furnace arrangement according to the invention is particularly advantageous in terms of manufacturing costs, even when the stove is formed for larger sauna spaces. In this case, the external dimensions specified by the heating • power requirement are well matched to the external dimensions
