Disclosure of the invention.

According to FIG. 1-10 stove for a bath with separate steam room, sink and a waiting room contains a single-wall metal rectangular case in which the furnace 9 is placed with loading door 5, with a grate 8 and ashpit 6. Above the furnace 9 a container (heater) 3 for heat storage elements (stones ) 14. The cavity of the furnace 9 is connected through a system of air ducts to the chimney 2. On the side of the furnace 9, a tank 1 is installed to heat the washing water. The furnace 9 with the heater 3 is designed to be placed in the steam room (steam room) bath, and adjacent to the furnace 9 tank 1 for heating the washing water - in the washing room (sink) bath.

In addition to the heat-accumulating elements 14 of the stove, the heat-accumulating furnace is equipped with a block of collapsible heat accumulators (СРТА) and seats for them. The SRTA unit includes a frontal heat accumulator (FTA) 10 for heating a waiting room, a longitudinal heat accumulator (PTA) 11 for heating a steam room and a sink, and also a conventional heat energy accumulator (KATE) 15 for additional heating of a steam room. FTA 10 is made in the form of a collapsible rectangular panel with a landing opening, and its seat 12 is in the form of a loading tunnel installed between the loading door 5 and the entrance to the furnace 9 of the furnace. PTA 11 is made in the form of an L-shaped panel, partially separating in the vertical plane of the sauna room and washing room, and the seat 13 for it is in the form of a rectangular metal plate installed on the upper side of the body of the furnace 9 parallel to its longitudinal axis. KATE 15 is made in the form of two collapsible panels with ventilation windows 16, installed perpendicular to each other along the free sides of the furnace 9 of the furnace and with a gap between their inner walls and the furnace body. To increase the heat accumulating ability of KATE 15, its heat-accumulating panels are installed at a distance of 8-10 cm from the free sides of the furnace.

Collapsible panels of heat accumulators 10, 11, 15 are made of heat-accumulating elements in the form of bricks or figured blocks with a facing ceramic coating and assembly locks. The heat-accumulating elements 14 of the heater 3 are made in the form of oval natural stones and / or their fragments, and the heat-accumulating elements of the battery panels 10, 11, 15 are made of fireclay material, clay and / or quartz sand by the method of cold or hot pressing. While the rectangular metal plate 13 for landing PTA 11 is made of a thickness (3-5 mm), long (300-700 mm) and a width (80-200 mm). The boot tunnel 12 is made long 100-400 mm and with transverse dimensions of 300-600 mm, 300-500 mm in height and width, respectively. Kamenka 3 of the furnace is additionally equipped with a steam generator 7, made in the form of a dispenser (funnel for water) with a pipeline. The funnel - a steam generator 7 dispenser is installed in the upper part of the heater, and the end of its pipeline is placed in its lower part under the heat-accumulating elements of the heater (not shown in the figures).

Heat-accumulating furnace for a bath works as follows.

The fuel is loaded into the furnace 9, the furnace is loaded from the waiting room (Fig. 10) through the door 5 of the furnace and the loading tunnel 12. Next, the fuel is ignited in the furnace 9. When the fuel burns, the metal walls of the furnace 9 heat up. Thermal energy of the upper surface of the furnace 9 is transferred to heat storage elements (stones ), located above the firebox in the heater 3, which accumulate heat for the steam room. At the same time, the front part of the firebox 9, which is in contact with the front battery 10, heats it and transfers part of the accumulated energy to the waiting room. The longitudinal accumulator PTA 11, located on the upper side of the furnace 9 through the landing plate 13, accumulates its heat, the heat of the heater 3 and the chimney 2 for subsequent slow return by the walls of the accumulator 11 to the accumulated heat to the air in the steam room and the washing room. At the same time, water located in tank 1 additionally accumulates heat from the furnace for the washing room. KATE 15, located on the sides of the furnace, at the expense of the convention effect, draws in the cold air of the steam room through the ventilation windows 16 located in its lower part, and drives the air of the steam room in the space between the heated side walls of the furnace and the inner walls of the battery 15. The heated conventional air heats the air in the steam room and some of its heat gives off to the KATE 15 battery and its heat-accumulating panels in contact with the air of the steam room. To adjust the humidity in the steam room, use steam generator 7. To do this, water is poured into the funnel dispenser of the generator 7, which slowly penetrates into the lower layers of the stones of the heater through the appropriate calibrated pipe. Due to the elevated temperature of the lower layers of stones 14 of the heater 3, the water evaporates quickly and the steam room air is saturated with fine water vapor.

Industrial Applicability.

The invention was developed at the level of a prototype. A test of the prototype in Russian wooden baths with separate steam baths, a sink and a waiting room showed the possibility of preserving heat in the indicated rooms with an acceptable residual temperature for soaring at least 60 ° C, washing at least 25 ° C and changing rooms at least 20 ° C for 3 hours after stoking the furnace at an external ambient temperature not lower than “-10 ° C”.
