SAUNA FURNACE Russian patent published in 2016 - IPC F24B1/02 F24B9/00 

FIELD: heating.

SUBSTANCE: invention relates to designs of furnaces when equipping saunas. Furnace comprises metal body 1 with built-in heater 6. Between the walls of the heater 6 body and body 1 of the furnace flue ducts 8 are made binding furnace 2 with chimney 5 along all the sides of heater 6 and with its upper side. Heater 6 is equipped with loading recess 9 with door 10. At the bottom of recess 9 there is funnel 11 for water with dropper 12 and branch pipe 13, free end of which extends into the lower part of heater 6 into the thickness of its heat capacity material 7. On the outer side body 1 of the furnace is coated with heat insulated jacket 14. Jacket 14 is installed above body 1 of the furnace with a clearance forming convector 15 for air heating between walls of body 1 and jacket 14 walls. For heat exchange of convector 15 with heated air with ambient medium of the steam room of the sauna in the lower side parts of jacket 14 there are inlet holes 16 for cold air, and in the upper part of the jacket - holes 17 with gate valves 18 for dosed discharge of heated air in the steam room of the sauna. Convector 15 cavity is connected through rotating knee 19, ash pit 3 and grate 4 with furnace 2 chamber.

EFFECT: higher rate of heating, higher quality of steam, reduced capacity of rigid infrared radiation and the possibility of controlling temperature of heated air.
