Description

 The invention relates to the design of furnaces and can be used in bath equipment.

 Known furnaces for baths, comprising a housing, a furnace with holes in the vault, an ash pan, a heat exchanger with an accumulating nozzle (heater) located above the furnace, a gas duct connected to the furnace, the heat exchanger equipped with a pipe with a check valve for supplying water (ed. St. N 998822, C. F 24 B 9/02, 1973). In these furnaces, steam passing into the steam room through the doors in the housing is formed as a result of evaporation of water supplied to the heater, heated by flue gases passing from the furnace to the heater through openings in the furnace vault.

 The disadvantage of this furnace is the possibility of flue gases entering the steam room, as well as the content of a large amount (with a relative humidity of 60-70%) of droplets heated to the boiling point of water in the steam, which can have a negative impact on people's health.

 Closest to the claimed invention, the technical solution is a bath furnace containing a metal housing in which a firebox, an ash pan, a chimney and a stove are placed, made in the form of a container insulated from the firebox, filled with heat-resistant material (ed. St. N 1633233, class F 24 B 1/02, 1991).

 The disadvantage of this furnace is that it can only work in the Finnish bath mode with a low moisture content in dry steam, which is a heated gas mixture of ionized particles, which are an environmentally harmful factor and their systematic effect even on a healthy body can have negative consequences.

The technical result is to eliminate the above disadvantages, namely: increasing the positive impact on human health by supplying superheated steam to a steam room with a temperature significantly higher than the boiling point of water at a relative humidity of 30-50%
The technical result is achieved by the fact that in a furnace for a bathhouse containing a metal body, in which a firebox, an ash pan, a chimney and a stove are placed, made in the form of a container insulated from the furnace, filled with heat-resistant material and having a door for steam output, in a tank filled with heat-resistant material , there is a pipe for supplying liquid, made in the form of a pipe with holes at the end passing into the heat-intensive material. If the chimney pipe passes through a layer of heat-sensitive material, the pipe for supplying fluid has a section made in the form of a coil covering the chimney. Partitions with offset can be made in the heater, providing a zigzag passage of steam from the holes in the nozzle to the doors.

 Figure 1 presents the oven; figure 2 is the same, top view.

 The furnace for the bath contains a metal casing 1, in which a furnace 2, an ash pan 3, a chimney 4 and a stove are placed, made in the form of a container 5 insulated from the furnace 4, filled with heat-resistant material 6, and having a door 7 for steam output. In the tank 5 there is a pipe 8 for supplying fluid from the tank 9 to the holes 10 at the end of the pipe 8 extending deep into the heat-absorbing material 6. The pipe 8 has a section made in the form of a coil 11 covering the chimney 4. Partitions 12 are displaced in the heater relative to each other so that for steam coming from the openings 10 to the door 7, a zigzag passage is formed. Over the heater can be installed capacity 13 for hot water.

 The furnace operates as follows.

 The flue gas obtained from burning fuel in the furnace 2, located in the metal housing 1, passing through the chimney 4, heats the heater, made in the form of a container 5 isolated from the furnace, filled with lumpy heat-resistant material 6. From the tank 9, a liquid is supplied through the pipe 8, which being heated by the heat coming from the heat-intensive material 6, and passing along the coil 11 surrounding the chimney pipe 4, it passes through the hole 10 into the interior of the heat-resistant material 6. From contact with the heated heat-resistant material, the liquid evaporates and steam passing through a zigzag passage formed by partitions 12, and between pieces of a heat-consuming material, it overheats and overheats through the door 7 into the space of the bath. Ashpit 3 serves for the deposition of ash and air for combustion.

 The furnace of the proposed design allows you to submit to the steam room environmentally friendly optimally dry (with a relative humidity of 30-50%) superheated steam, which has a beneficial effect on the human body.
