Description

The utility model relates to thermal engineering and can be used in bathhouses for individual or collective use to produce superheated steam and create a comfortable bathing atmosphere for taking bath procedures.

Known superheater installed in the oven for a bath according to the patent of the Russian Federation No. 2359173 F24B 1/24 F22G 1/10 IPC publ. 06/20/2009, which is a steam generator. equipped with a moisture-falling device and a chamber with a heat-accumulating load located above the furnace, containing a steam swirler in the form of a volute located in the chamber with a heat-accumulating load and a pipe connected at one end to the volute and located in the furnace or above the furnace with the possibility of steam escaping through an opening in it into the room baths.

The disadvantage of this superheater is the use of heat storage load to produce superheated steam, which leads to more complex and expensive design. Superheaters with heat storage load have low efficiency, since a large amount of heat is spent on maintaining the high temperature of the stones, which results in a long process of steam formation. Non-removable design prevents it from being used in other ovens

Known superheater installed in the furnace for baths according to the patent of the Russian Federation No. 154892 F24B 9/00 IPC publ. 01/09/2013, which is a superheater connected by a channel to a cavity for water evaporation, formed by walls, part of which are the furnace surfaces heated to the boiling point of water.

The disadvantage of this superheater is the complexity of the design, the long process of steam generation, low efficiency, since evaporation occurs from the surface of the water, it is necessary to wait until the water heats up and begins to evaporate. In addition, when water evaporates, salts are formed that cannot be removed. The superheater is heated only from one side, respectively, the steam moves between the heated wall and the conditionally cold wall, which does not provide sufficient superheating of the steam.

The closest analogue of the claimed invention is an electric steam generator according to the patent of the Russian Federation No. 87912 A61H 33/06 F24C 13/00 IPC publ. October 27, 2009, made in the form of a metal water evaporation chamber containing several consecutive cavities, each of which is formed by a wall associated with a heat source that provides heating of said wall to a temperature not lower than the boiling point of water, and a profiled element installed on said wall , moreover, the cavities are sequentially connected to each other so that water from the previous cavity enters the subsequent cavity, while each cavity has holes for steam to escape, and the upper cavity of the evaporation chamber is made open for supplying water to the chamber. The steam generator is additionally equipped with a carrier panel, a protective and decorative convector and a water tank, and an electric heating element is installed as a heat source, tightly adjoining the named heated walls of the evaporation chambers, closed from above by a perforated wall, and forming a steam generation unit with them, which is placed in a housing and closed with a protective mesh, the water tank, equipped with one dosing tap, is installed above the steam generation unit and separated from it by a screen with holes for water to flow, forming a niche with a protective mesh and a protective and decorative convector, with a window for steam outlet, and a carrier panel made with the possibility of attaching a housing, a water tank and a protective and decorative convector on it.

The disadvantage of the steam generator is the insufficient quality of the superheated steam, since additional superheating of the steam occurs in the space where the heating element is installed, where the superheated steam mixes with the heated convection air passing through the body of the steam generator and exits into the niche. Due to the lack of a closed space, steam does not linger there for a long time and, accordingly, does not overheat enough.

Also, the disadvantage is the high metal content of the steam generator design, which leads to its rise in price. The steam generator is used only as an independent product, therefore, additional devices are required in the bath room, for example, a hot water tank, which limits its functional use.

The objective of the proposed utility model is to create a simple, inexpensive and easy-to-use superheater design, which is universal for any type of furnace, which allows to reduce the heating time of the bath room and obtain high-quality superheated steam that is comfortable for the user.

The problem is solved due to the fact that the superheater for bath rooms, containing a metal chamber for evaporating water, containing successively located cavities formed by a metal wall and a profiled element, and the cavities are sequentially connected to each other so that water from the previous cavity enters the next cavity, with At the same time, each cavity has openings for steam outlet, according to the formula, the water evaporation chamber additionally contains a metal wall forming, together with the water evaporation chamber, a steam overheating chamber in the form of a closed space, while the device is made with nozzles for water inlet and outlet of superheated steam into the room and is made with the possibility of installation in the furnace furnace.

The problem is also solved due to the fact that the superheater is made of stainless steel and is installed in the furnace furnace in such a way as to ensure the maximum heat transfer rate of the flame.

The superheater is made removable.

The specified set of features is significant and new, since the design of the device case assumes contact with water of all surfaces of the case and provides heating of the entire surface of the case to a temperature sufficient for water evaporation and steam overheating. Evaporation of water from a metal surface occurs intensively due to the high thermal conductivity. In the proposed superheater, the evaporation of water occurs precisely from the metal surface.

Simplicity of execution and low material consumption is ensured by the design and is a device consisting of a water evaporation chamber and a steam overheating chamber.

The water evaporation chamber and the steam overheating chamber are formed by dividing the internal space of the device with a profiled element connected to one of the walls of the device by welding.

The profiled element contains sequentially located cavities that ensure the sequential flow of water from the previous cavity to the next one until complete evaporation.

Each cavity has openings for steam to exit into a closed space, which is a steam overheating chamber. The closed space of the steam superheat chamber ensures that the steam is retained for superheating and is directed to the steam outlet.

For ease of use, the superheater is made with a pipe for water inlet.

The device is made of stainless steel, which reduces the presence of iron ions in the steam.

For the fastest possible heating of the metal surface from all sides to high temperatures, the superheater is installed in the furnace furnace in such a way as to ensure the maximum heat transfer rate of the flame.
