Description

Technical field

The claimed solution relates to the field of thermal technology and can be used to produce steam in individual and collective baths.

State of the art

Known utility model RU 176778 U1 “Steam-generating furnace with an aerodynamic heat exchanger” containing a furnace, a chimney, a water tank, the heat exchanger is made in the form of a hollow tank formed by the wall of the chimney and the heat exchanger body, at least one aerodynamic element is installed in the heat exchanger cavity, and the tank for water contains at least one hole connecting the cavity of the water tank with the cavity of the heat exchanger.

Intensive heat flow from the furnace and from the walls of the chimney pipe bring the water inside the tank to a boil. The filler cap is tightly closed and an excess pressure of moist steam is created inside the water tank. Due to this, wet steam is forced through slotted openings into the cavity of the aerodynamic heat exchanger, which is formed by the outer surface of the chimney and the inner surface of the aerodynamic heat exchanger body. The rectilinear (laminar) movement of wet steam along the surface of the chimney along the shortest path to the exit is prevented by an aerodynamic element in the form of a spatial spiral and makes wet steam move around the chimney. Having made several turns, wet steam receives enough thermal energy so that at the exit from the upper part of the aerodynamic heat exchanger dry superheated steam enters the steam room atmosphere.

A disadvantage of the known solution is that the heating area of the upper base of the boiler and the flue pipe is small compared to the volume of feed water, which leads to a rather slow heating of the water to a boil, and requires constant maintenance of the temperature inside the furnace.

Known utility model RU 172122 U1 “Removable heater for a bathhouse” made in the form of a tank without a bottom, equipped with a closed removable lid with a funnel, and a pair of opposite side walls of the tank is made elongated. The removable closed heater is preferably located inside the open heater. Water is dosed in a metering way into a removable closed heater through a funnel and evaporates, steam passes through an open heater. Steam and excess water, which did not have time to evaporate, leave through the provided slots formed between the side walls of the heater and the surface of the furnace.

The disadvantages of the known solution is that the steam leaves through the cracks formed between the side walls of the heater and the surface of the furnace, which is insufficient. In addition, the supply of feed water to the heater is carried out pointwise in one place, which is not effective since only a small area is involved in the generation of steam. Another disadvantage is the heating of stones only due to their contact with the surface of the upper base of the furnace, which slows down the heating process and the formation of steam. Another drawback is the removable cover equal in area to the upper base of the heater, which increases the likelihood of steam leakage.

Disclosure of the invention

The objective of the claimed solution is to develop the design of a closed heater more efficiently generating steam and more quickly saturating the room with steam.

The claimed task is achieved due to the design of the closed heater which has a device for supplying feed water to the stones supplying water at several points.

The connection of the tank (1) with the channel (3) can be carried out by a weld, or through connecting elements.

In the case of the connection of the container (1) with the channel (3) through the connecting elements, such a connection can be made through the fitting (2) including a threaded connection.

The fitting (2) can be mated to the container (1) with a welded seam or, in the particular case of execution, the container (1) can have a pipe (1.4) with a thread on the bottom on which the fitting (2) is mounted.

By type of fitting (2), at least the tee of FIG. 2-3 or its type which allows you to connect the tank (1) with at least one channel and loop it FIG. 4.

In the particular case of execution, a fitting (2) can be used that allows you to connect the container with several channels while looping them.

Channel (3) of FIG. 4, 5 is an element having an internal cavity for the passage of feed water (6) and at least two holes (3.1) in the walls.

The channel (3) is looped through the connection with the tank (1).

In the particular case of execution, the channel (3) may have turns and / or loops. The length of the channel is determined by the size of the space inside the heater and the demands of the user.

The holes (3.1) can be located both in the same plane and in different ones.

Channel (3) can be flexible, which allows you to place it randomly in the heater.

It should be noted that the feed water supply device for generating steam of FIG. 2 is mounted on the lid (4.4) in such a way that a container (1) is located on the outside and a channel (3) on the heater side.

The heater is filled with stones placing a channel (3) in it, so that as many stones as possible subsequently receive water to form steam.

It should be noted that the channel (3) can be located above the stones (5) and / or under the stones and / or around the chimney (4.1).

In the particular case of execution, the feed water supply device can be additionally equipped, through the fitting under the tank (1) with an additional tank, for continuous steam formation and condensate collection when the heater cools down.

As a result, the claimed design of the closed heater generates steam more efficiently by distributing the feed water over the heated stones, faster creates excess steam pressure inside the closed heater, and the openings at the bottom of the casing make it possible to saturate the bath room with superheated steam faster. At the same time, due to the design, it is not necessary to manually pour water on the stone laying in order to receive water vapor, since the feed water supply device independently for a long time, while there is a supply of water in the tank, it allows to fill the bath with steam.
