Description

The invention relates to sanitary and hygienic structures, in particular to sauna stoves in urban baths and health complexes.

A metal furnace is known (see RF patent No. 2359173, 2009), containing a body, a firebox, a chimney, and an additional chamber with a heat-accumulating load located above the firebox. The steam generator contains a steam vortex generator, for example, in the form of a volute, located in a chamber with a heat-accumulating load, and a pipe located in the firebox or above the firebox and connected at one end to the volute, and the other to an additional chamber with a heat-accumulating load.

The disadvantage of this furnace is the location of the heat-accumulating load above the firebox. This arrangement does not provide complete and comprehensive heating. A steam vortex generator in the form of a snail does not sufficiently superheat the saturated steam, since the snail is located in the heat-accumulating load zone, separate from contact with the heating element, and the steam, when passing through a short pipe located in the firebox or above the firebox, is connected at one end to the snail and the other to an additional chamber with a heat-accumulating load does not have time to overheat to the required temperatures.

The “Geyser” sauna stove is known (see RF patent No. 2250417, 2005), which contains a metal body with a firebox, a chimney and an open container with heat-exchange heat-storing material. The specified open container is located in the upper part of the firebox on the side of the heated room. The firebox contains a high-pressure container with a heat-exchange heat-accumulating material and a moisture distribution device installed in its upper part, connected to a tank for vapor-generating liquid through a dispenser. A throttle pipe is built into said container from bottom to top, passing through the heat exchange and heat storage material into said open container. The above-mentioned pipe provides additional superheating of the steam formed in the high-pressure tank in the upper part of the furnace and due to recuperative heat exchange with the heat-storing material.

The disadvantage of this stove is the location of an open container with heat-accumulating material above the firebox, which is ineffective for a Russian bath due to the impossibility of all-round heating of the container. With this design, heat storage materials are located in an open container, heating occurs largely by convection through or around the heat storage materials and can overheat the steam room. With a constant dosage of liquid onto heat-storing materials, they cool and the steam turns into a wet state and can create breathing discomfort. Heating steam in a bathhouse using a high-pressure container is also undesirable, since it creates additional danger in the event of an increase in steam pressure.

The closest solution (prototype) in terms of technical essence and set of essential features is the Kutsenko aquastove (RU patent No. 2499957, 2013), made in the form of a metal cylinder with double walls, with the ability to fill the space between the walls with water or other coolant. The outer walls of the aqua furnace are equipped with a hole for supplying and discharging water and steam.

The aquastove contains a main chimney, a firebox with a blower, above which there is a closed-type heater, in the upper part of which there are holes for supplying water and removing water vapor, the walls of the aquastove are made double with the possibility of filling the space between the walls with water or other coolant, while the outer walls of the aquastove equipped with a device for supplying and removing coolant, the aquastove is additionally equipped with an air supply system to the upper combustion zone of the first bell and an internal chimney, and they are made in the form of a pipe and/or several pipes located parallel to the walls of the aquastove in such a way that the additional air supply system to the upper the combustion zone in its lower part is located in the ash pit, and its upper part is located in the upper combustion zone of the first hood, the internal chimney in its lower part is as close as possible to the firebox, and in its upper part it minimally protrudes above the surface of the first hood, and the main chimney is located in the second hood in such a way that its lower part is as close as possible to the partition between the first and second hoods, while the firebox is lined.

The disadvantage of this stove is the uncontrolled supply of wet steam in the steam room, large heat loss through the chimney, since the chimney in its lower part is as close as possible to the firebox, and increased humidity of the steam, which creates problems for the respiratory system of users, rapid premature wear of building structures and finishing steam room

The technical result is an increase in the efficiency of the device during its use due to improved design.

It is achieved by the fact that in a known device containing a metal body, a main chimney, a firebox with a blower, above which a closed-type heater is placed, the walls of the aquastove are made double, with the ability to fill the space with water, while the outer walls of the aquastove are equipped with a device for supplying and discharging coolant , the aquastove is equipped with several holes for air supply in its lower part, and the firebox is equipped with a hole for installing a gas burner, the body of the aquastove is made rectangular, an additional superheater is installed, consisting of two cylinders filled with heat-accumulating material with high thermal conductivity - cast iron cores, interconnected by a horizontal pipe and two vertical pipes, one of which is connected to a pipe on the furnace body for removing and supplying steam, and the other is connected by a pipe to a perforated L-shaped pipe, which also has a pipe for removing and supplying steam, the pipes are fixed on the top panel of the furnace, the lower part the heater and the superheater are close and located above the horns of the gas burner, the heater has a neck with a hole in the upper part, rigidly connected to the top panel of the stove, equipped with a square metal lid, fixed on hinges, a metal handle with a wooden insert for regulating the water supply and steam removal, the heater installed with a gap in relation to the body for better heating of the heat-accumulating material on all sides and the passage of released gases, on the outer side walls of the furnace on both sides of the furnace body there are pipes for supplying and discharging water and steam, the combustion tunnel of the aqua furnace and the gas burner are made remote, with In this case, the top panel, heater, combustion tunnel, and superheater are designed to be dismantled.

The proposed aquastove produces three types of steam: superheated steam with a temperature of 360°C from a superheater, this steam gently and gradually fills the steam room with heat without over-humidifying it; finely dispersed steam from the heater is generated at the user’s request when water is supplied to the stones; saturated steam with a temperature of 110°C enters the adjacent room and heats it (Turkish steam room - hammam), this type of steam can also be used for hot water supply: heating through a boiler heat exchanger, heating water in a swimming pool, heating a water heated floor. The aquastove saves energy, in this case natural gas, thanks to stable flame combustion, automatic adjustment depending on the set temperature and the presence of a superheater. The aquastove is safe because it is made of stainless steel and the parts are welded together using argon welding, the perimeter of the firebox between the walls is filled with water, and the chimney heats up no higher than 100°C, combustion products pass through the space between the heater and the body along the entire height of the aquastove and give off their heat to the heater, the walls of the stove body and water. The aqua stove does not overheat the steam room, since the water between the walls of the stove prevents the body from overheating.

The drawing shows the proposed aqua furnace (Fig. 1 - rear view, Fig. 2 - front view, Fig. 3 - side view)
