It is known in the art to provide a shield over a stone space in a sauna heater. The main purpose of the shield is to prevent objects that could present a fire hazard from being placed near / on the rocks. On the other hand, however, the shield 15 must allow the water thrown into the heater to reach the rocks. Such protections are described, inter alia, in Internet references [1] and [2].

However, the prior art sauna heater shields even attract 20 to place objects under the heat of the heater. Due to the relative position of the well-known shelters and sauna heaters, bathers may have the impression that the sauna heater heater guard • ·· is specifically designed for drying towels or clothes in general above the sauna heater.

• ·; In this case, the true function of the shield will completely turn over.

• · ·. , ·) This is really dangerous especially for the sauna fire • · ·. !! safety.

• · • · ·· ·. The object of the present invention is to provide an improved safety • ♦ · * ”delta heater, a protective structure suitable for a stove and a method to improve the fire safety of a steam room. The features of the invention are described in the patent. The characteristics of the method for improving the fire safety of a steam room are set out in claim 8.

The sauna heater according to the invention has several advantages. First, the mutual positioning of the sensor means and the protective structure with respect to the overheating of the heater results in the heater being automatically switched off if additional objects are placed on the protective structure so as to create a fire hazard. This is achieved by the fact that, when covering the protective structure, it forms an airflow space into which the airflow space, or generally the area of influence of the airflow space, is provided with sensor means.

10

According to one embodiment, the protective structure may have been configured such that placing objects too close to the sauna stones is difficult in all respects. However, the user-friendliness of the heater will not deteriorate. In addition, the protective structure itself may also provide a construction such that the articles remain poorly supported on the protective structure. When the protective structure is uncovered, ie without hanging, the heater normally operates, releasing heat to the steam room. Covering the protective structure restricts airflow. As a result, the effect of the air flow caused by the heater is more focused and at the same time the sauna stones are sufficiently isolated from the steam room itself. The result of the alignment is that the upward flow of the stove to the steam room is limited and more focused on the sensor means which are in the airflow state resulting from the covering:, ·. 25 or at least within its immediate range.

• · · ·· * · • · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · According to a preferred embodiment, the protective structure forms a · · oblique rising continuous structure which starts from the • front edge of the heater and rises towards the rear edge of the heater. This type of construction is suitable, for example, for wall mounting the stove. According to another embodiment of ♦ · ***, the protective structure may form a cross-section of the heater ··· • · · ϊ. *, Which is high relative to the heater, which is mainly outside the heater stones. Here, too * *: * ··, the 35 airflow space formed during concealment can still be talked about, since the interior defining area of the protective structure is, however, always more spacious than, for example, • · 3 118560 the protective structure without even a single cover.

Other features of the invention will be apparent from the appended claims, and other advantages of the invention are mentioned more fully in the specification.

The heater, the protection structure and the method according to the invention, which are not limited in any way by the following embodiments, will be further described with reference to the accompanying drawings, in which:

Figure 1 shows a first example of a sauna heater according to the invention as a wall-mounted installation,

Fig. 2 shows another example of a 15 heater according to the invention as a wall arm assembly,

Figure 3 shows a third example of a heater according to the invention as a central floor installation,

Figure 4 shows a fourth example of a sauna heater according to the invention as a wall arm installation and Figure 5 shows an example for opening a protective structure in the sauna heater according to Figure 1.

Y: Figures 1-4 show some examples of the heater 10 according to the invention 10. The heat source of the heater 10 may in its basic form be an electric heater 25. The electric heater 25 has a jacket · · ♦ ·: Surrounded by a stone room with resistors (not shown) 15 ···. ***. for sauna stones 17. The stove 25 can be set up against the floor · * · 29 as shown in Figure 3 and / or attached to its sides. structures such as wall 21 in Figures 1, 2 and 4.

• · · · »·. ···. 30 • The stove 25, also mounted against the wall 21 or generally near the wall 21, can lean against the floor 29.

The basic equipment of the stoves 10 according to Figs. 1-4 includes the following:: · *: also the protective structure 18 and the sensor means 14 for the ovens 10 in case of overheating (for example, High Limit-Control). for observation and treatment. The protective structure 18 is located between the stone space 15 and the steam room 12 118560, whereby it separates them. Here, the steam room 12 is defined as the space defined by the walls, floor and ceiling where the benches and the stove 10 are usually located. However, the protection structure 18 allows for undisturbed access of water to the stove stones 17 which can be arranged in the stone space 15 5 and also to the air space 12 for the steam room 12. Furthermore, the shielding device 18 which also forms part of the stove 10 in an identified overheating situation and / or a corresponding alarm is given. In this case, the sensor means include at least one overheat sensor 14 connected to control electronics (not shown) of the heater 10 known per se. The control electronics known per se can either be in the electric stove 25 itself and / or may also be located outside the steam room 12.

In the heater 10 according to the invention, the protective structure 18 is, when covered, arranged to form an airflow space 19. The airflow space 19 and the airflow are illustrated by the arrows 20 shown in Figures 1, 4 and 5. By covering the protective structure 18 herein it is meant, for example, that the protective structure 18 closes at least locally at some point. As a result, the access of airflow from inside the containment structure 18 to the steam room 12 at the relevant *: ** covered point is more limited compared to at least: * * 25 than if that point were uncovered. As a result of the obstruction, the air flow increases at another point.

··· • · · · · · ···

At least sensor devices adapted to sense overheating • · *. 14 is relative to the protective structure 18 such that, when covered by ·· * 30, the protective structure 18 is located in the resulting airflow · »· background area 19. More generally, as a result of the covering, J ·« * ..! the area of influence of the formed airflow space 19. In this case, the sensor 14 may be located, for example, inside the guard 18. On the other hand, the sensor 14 may also be outside the guard 18 (e.g., · · *. **: 35 above it). The effect of the resulting airflow effect is clearly also exerted on the outside of the shield 18, with the sensor 14 mounted near the shield 188560, which means that the airflow effect on the sensor 14 can then be said to be sufficiently perceptible relative to the airflow 18 masking.

In the embodiment of Fig. 1, the sauna heater 10 according to the invention is shown as a wall arm or generally near the wall 21. Now the protective structure 18 may be at least on one side 20 adjacent the structures 21 defining the steam room 12, which structure is now at least one wall 21. The protective structure 18 an inclined structure for covering the stones 17 in the stone space 15. The structure begins at the leading edge of the stove 15, from where it rises steeply towards the wall 21. At both edges, the structure is vertical and inclined horizontally to an oblique front. The steepness of the elevation is adapted such that the distance of the article placed over the shield 18, such as Textile, from the heater stones 17 or a similar heat source, does not cause immediate article carbonation or, at least, ignition. In Figure 1, the article is a towel P hung on a rib 24 on the oblique plane portion of the shield 18.

Y; On the other hand, the steepness of the front plane of the shield 18 also achieves the fact that the article P is poorly oblique on the wall, which makes it substantially difficult to place it on it.

· »* · • · ♦ • · M ·

As an example of the steepness, 45 to 90 degrees, and even more than 90 degrees may be mentioned, as in the embodiment of Figure 3. . ·. can be seen. In other words, the height of the protective structure 18 can be said to be in this case multiplied by the width or length of the heater 25 t or the stone space 15. A sufficient height of the protective structure 18 provides a sufficient degree of stiffness. In this case, the protective structure 18 consists of transverse ribs 24 disposed at a distance from each other and attached to the frame structure 23. In addition to or instead of the transverse and vertical ribs 24, the oblique ribs are also suitable. The arrangement of the fins 24 relative to one another is such that it does not hinder the water being thrown onto the heater 25.

6 118560 5 The safety net 18 need not even be very steep. Up to 45 degrees can also be considered. If the sensor 14 is within the protective screen 18 and the protective screen 18 is covered with a towel P, the sensor 14 easily detects a closed airflow (heating) and interrupts the power supply to the heater 25. 10 It should be understood that the invention is not intended to be limited to any particular steepness.

The screen 18 is now secured to the wall 21 by the frame members 23 facing the wall. The screen 18 may also be supported by its lower part 15 on the heater 25. The top of the screen 18 has a cover plate 27 under which the overheat detector 14 is now secured 14.1 heater 25 for electronics, which may be known per se. The actual overheat reset switch 20 may be located, for example, at the bottom of the stove 25, from which the overheating can be "reset" and the stove 25 can be reset.

Figures 2-4 illustrate some other embodiments of the invention ♦ · ·; ··; Figures 2 and 4 show another •: *; 25 example of a wall arm design. In them, the sensor 14 is in the wall 21.

· «· · • j *. Figure 3 shows an example of a central floor design where sensor 14 can * ··. ***. to be on the ceiling or inside the shield 18 as it is now. As can be seen in Figure 2, the ribs 24 may also be vertical. . ·. SIA. Vertical lining 24 is equally applicable to Figure 1. ···. 30 wall arm application. The vertical wrapping alone · · · 24 makes it even more difficult to hang towels P in the • · · * ..! * Safety net. On the other hand, in horizontal wrapping, the length of ribs • ♦ * ·; · * can also be shortened by making the frame structure ♦ * · * “dense (mesh), which makes it difficult, for example, to place a towel on horizontal wrapping. The protective cage 18 may now extend, for example, above a person's height, for example 200 to 250 cm from the floor level. On the other hand, the safety net 18 can always be limited from above to the ceiling of the steam room 12. In this case, the heater 10 as a whole always forms a floor-to-ceiling structure.

7 118560 5 As can be seen from the towel P projected in Figure 2, the towel P is no longer above the stones 17. Again, the towel P suspended in the shield 18 can be said to constitute an airflow space 19 even when only one and only one side of the net 18 is hung. Despite the remaining open sides of the shield 18, the protective structure 18 is even more spacious than at least one side. towel P or the like on any one of the 18 sides of the protective structure.

In the embodiment shown in Figure 4, the angle between at least a portion of the cross-sectional plane defined by the stove 25 and the vertical walls of the safety net 18 is greater than 90 degrees. This is achieved, for example, by the fact that the cross-sectional profile of the safety net 18 is higher at the top than at the bottom (d2> di). The measurement differences between the profiles 20 need not be large. This downwardly narrowing cross-sectional profile of the safety net 18 results in j * · .. that, when hanging towel P on transverse rib 24, it: V · hangs down directly due to gravity. Thus, due to the downward flowing mesh structure 18, towel P hangs •; * · 25 detached from the mesh 18. Risk of carbonization / ignition of towel P • ® · t • · *. is now even smaller. Also, the now freely hanging # ··. * ”» Textile P hanging on the protective screen 18 provides an airflow space 19, whereby the thermal effect of the heater stones 17 is directed to the sensor line, · ·, line 14, being the wall 21 or • · · ·· *. * ·. 30 ceiling mounted sensor 14.

···· · · · ♦ • · * The application of Figure 5 illustrates one way to access your handheld stones, for example, stove stones 17. This may be necessary when changing or tune stones, for example:: ** on the rocks, for example, various scent vaporizers, "the spirit of the steam." Now at least part of the protective structure 18 is arranged so that it can be opened or generally moved away from the heater stones 17. In an embodiment, the oblique planar ribs 24 are movably disposed in frames 23 at their ends, whereby they are lowered and assembled into a bundle at the front edge 5 of the stove 25. In other words, the frames 23 here form the rails 24 on the ribs 24, more generally, the opening-closing mechanism 28. The ribs 24 at their ends may be connected to each other by, for example, a pleated cable (not shown). It defines the distance between the fins 24 as they outline the bevelled front face of the protective structure 18.

Of course, the ribs 24 of the front of the cage 18 may alternatively also be fixed in the frames 23. In this case, the frames 23 may consist, for example, of a plurality of telescopically attached members 15. The telescopic arrangement enables the front 18 of the shield 18 to be lowered to the front edge of the stove 25 or raised up to the cover plate 27 (not shown).

As can be easily seen from the above embodiments 20, all of the above protective structures 18 are vertically unfolded. In the embodiments of Figure 3, there are four horizontal folds, each at 25 angles. In other embodiments, there are only two horizontal folds, each with a 25 · front edge of the stove. Since the folds are not vertical,:. 25, there is no plane or brush on which the safety net 18 could be formed
