OVEN FOR BATH Russian patent published in 2006 - IPC F24B9/00 

FIELD: domestic stoves or ranges for solid fuels.

SUBSTANCE: oven comprises furnace with solid roof, stone-cover above the roof, water tank above the stone-cover, gas duct that passes through the stone-cover and tank, and hollow chamber. The hollow chamber abuts against the roof of the furnace or the bottom of the water tank and furnace roof and chimney. The axes of the passages are shifted toward the opposite sides of the oven, and cross-section of the chamber is greater than that of the gas duct to provide generation of vortices due to the flow velocity drop in the chamber. The vortices propagate toward the other gas duct.

EFFECT: enhanced efficiency.
