Abstract

1. Sauna furnace containing a furnace with a grate, blown, bed for stones and a chimney, an air duct connecting the internal cavity of the blow with space under the floor, characterized in that the duct is equipped with a horizontal perforated section located under the floor. Sauna furnace according to claim 2, characterized in that the end part of the perforated section of the duct is made of a smaller section than the perforated section itself.

Description

The invention relates to systems for furnace heating - to furnaces that provide both heating and steam generation, is used in individual baths.

Known metal Kugkin furnace according to the patent for utility model of the Russian Federation No. 70562. F24B 1/24, publ. 01/27/2008, including a housing, a screen having at least one vertical section, a firebox with a door, wherein the width of the firebox is less than the width of the housing, an air-heating chamber located between the side walls of the firebox and the vertical sections of the screen, a metal container filled with a vapor storage hole filled with heat storage material placed above the firebox and having a common wall with it, and a chimney. A part of the furnace body connecting the container with the heat storage material and the screen is sealed, and an air intake element is located between the metal tank with the heat storage material and the air-heating chamber.

The disadvantage of this sauna stove is the low efficiency of heating the floor, as well as the bathhouse itself.

Also known is the bathhouse furnace according to the patent for a utility model of the Russian Federation No. 93500, F24B 1/24, publ. 04/27/2010, containing a housing, a firebox having an increased height, a chimney, an insulated closed heater having a lid for giving water to stones, a protective casing equipped with shutters for regulating the flow of hot air.

The disadvantage of this sauna stove is the low efficiency of heating the floor, as well as the bathhouse itself.

The closest solution to the technical nature and the set of essential features is a bath stove with an air duct under the hearth according to the patent for the invention of the Russian Federation No. 2291999, F24B 1/24, publ. January 20, 2007, containing an ash pan and a furnace with a cast-iron stone box placed above it, made so that the pocket of the box is at the level of the furnace and is the guiding surface of the chimney. The blower air intake is located below floor level and connects the blower to the underground. Under the hearth of the furnace there is a metal partition separating the duct from the chimney. An air duct for the steam bath entering the outside of the building and passing into the room between the metal partition and the furnace foundation is located between the metal partition and the furnace foundation.

The disadvantage of this sauna stove is the low efficiency of heating the floor, as well as the bathhouse itself, due to air entering the blower from the same place under the floor.

The technical result of the proposed utility model is to increase the heating efficiency of both the floor and the bath itself.

The technical result is achieved by the fact that in the bathhouse furnace containing a grate with a grate, it is blown, a bed for stones and a chimney, an air duct connecting the internal cavity is blown with a space under the floor, the duct is provided with a horizontal perforated section located under the floor, while the end part of the perforated section of the duct is made of a smaller cross section than the perforated section itself.

Figure 1 schematically shows the proposed bath furnace.

The sauna stove contains a firebox 1, with a grate 2, blown 3. a bed for stones (not shown in the drawing - it can be done by any known method), a chimney 4, an air duct 5 connecting the internal cavity of the blower with the space under the floor. The duct 5 is provided with a horizontal perforated section 6 (perforation is not shown in the drawing). The furnace can be installed either, as shown in the drawing, on the foundation 7 or on the floor 8 with appropriate thermal insulation of the floor from the furnace (this option is not shown in the drawing). The floor is equipped with ventilation openings 9. The end part of the perforated section 6 of the duct 5 is made smaller than the perforated section itself. This will ensure uniform intake of air from under the floor throughout the location of the perforated section of the duct 5.

Sauna stove operates as follows.

When the furnace is kindled, the blower 3 intensively starts to receive cold air from under the floor 8 through the duct 5 (its perforation). Under the floor 8, air from the bath enters through the ventilation openings 9. Due to this, there is an intensive movement of air from the space of the bath under the floor, and from there into the blower, which ensures good accelerated heating of the floor and the internal cavity of the bath.

The high heating efficiency of both the floor and the bath itself is the advantage and advantage of the proposed technical solution compared to the prototype.
