dens of the inner shell, a motor-driven ventilation to form a heat restoration space that is supported by the

terrad is arranged. the air passing through the furnace is largely unaffected

If the motor drive of this fan is used to heat the contents of the stone container, radcs designed to be adjustable, so you can also use the aprons from Advantage that the furnace is more efficient 5 extensions of the side walls of the stone container receives and that the desired sauna temperature is formed and the side walls of the stone container only can be regulated more precisely. Provided with openings in the upper area thanks to the motor-driven The driven fan wheel in the bottom of the inner shell is also part of the heating elements In addition, a reduction in the temperature gradient - the heat storage space below the stone container, les between the upper and lower lying areas on the one hand with regard to the risk of fire achieved in the sauna cabin. Otherwise only for security reasons and on the other hand to achieve Concentrating hot air in the upper area, which is at as uniform an air temperature as possible in the naturally only with cooling down sauna cabins are in further training of the event, is due to the increased suction in the lower manure in the upper area of the stone container and The area of the furnace is pulled down more quickly, so that the space between the inner shell and the shell is measured The sauna bathing temperature sensor for temperature control is also located in deeper areas becomes possible. and limitation are used, with these Another important design feature temperature sensors, the fresh air supply, the motorider The invention consists in that at least one internal drive of the fan wheel and / or the control system can be controlled within the outer shell and / or the intermediate 20 of the heating elements, shell opening fresh air duct is provided. In the following, the invention can now be used to supply fresh air from outside the sauna room using the example shown in the drawing. The particular advantage is that manure is explained in more detail.

the fresh air supplied through this fresh air duct. The drawing represents a vertical section air is fed directly into the heater and immediately heated there 25 represents a sauna heater shown in perspective. before entering the sauna room itself. The jacket forming the furnace housing has a in this way drafts of air are avoided. It is cubic in shape and consists of an outer shell 1. above all it ensures that the fresh air is also in the upper part of an intermediate shell 2, an inner shell 3 areas of the sauna cabin that are present enclose the interior space 4 vertically on all sides, and is not only close to the ground, like the outer shell I and the intermediate shell 2 as well as the two is known to the previously known sauna systems. Schcnschalc2 and Inncnschale 3 are each in horibci which the fresh air arranged through wall openings of the zontal distance from each other, so that Sauna cabin is led inside, where air shafts 5 and 6 are formed between them, Due to its lower temperature, it is equal to that of a cream cap 7 on top. The Zwiden Floor sloping. "35 schcnschalc 2 ends at a distance below the Another advantage of this measure is the framing 7, so that the air ducts 5 and 6 is achieved, consists in the fact that the temperature of the upper part of the jacket with each other in the outer shell of the furnace jacket are still further under the bond. The outer shell of the furnace jacket Temperature of the cabin air surrounding it gc- has several air inlet openings near the floor can be when the fresh air is at least 40 to 8. The inner shell 3 is slightly behind give away in part between the outer shell and the bottom 9, which is arched at the top, which is a central shell of the furnace shell is supplied. has opening 10. In this central opening bcfin-F.iue preferred embodiment of the invention de! the fan wheel !! an axial fan, which is characterized in that the intermediate shell can be driven by a controllable electric motor 12. at a distance from the bottom of the inner shell a 45. The intermediate shell 2 has a bottom 13. in the closed Has bottom, in which below sen center 14 a fresh air duct 15 opens. in the the opening of the bottom of the inner shell is a fresh upper part of the furnace there is a stone container air duct opens. The fresh air duct 16, the side walls of which are separated from the inner shell 3, can thereby be completely or partially closable, so that the certain horizontal distance have, so that Oven does not constantly suck in cold fresh air and 50 results in a gap 17 through the top its heat output thereby unnecessarily \ crreduced sheet metal 18 with a number of air outlet openings, z.
