Description

The invention relates to the field of household appliances, in particular to solid fuel heating devices used to heat air and produce steam in steam rooms of small baths.

Known furnace for a bath (RF patent No. 2005263, F 24 V 1/24, bull. No. 47-48 from 12.30.93), containing a furnace with a blower, a chamber with heat storage load associated with the furnace and the chimney and equipped with a door on one from its side walls. The design drawback is the long warming up of the heat storage load and the rapid boiling of water in the water tank, which leads to the release of a large amount of wet steam, which worsens the microclimate in the steam room. In addition, the metal body of the furnace with strong heating emits an unpleasant odor of scale.

The closest technical solution, selected as a prototype, is an oven for baths (RF patent No. 2011121, F 24 V 9/04, bull. No. 7 from 04/15/94), containing a housing, a furnace with a door and a blower, a chamber equipped with a door with placed on the grill heat storage with a load, the flue and the chimney associated with the camera and separated from it by a valve.

This design has the following disadvantages. Firstly, during the operation of such a furnace, hot gases from the furnace through the gas duct pass directly through the stones located in the chamber and, as a rule, are heat storage loading. On stones, products of incomplete combustion of fuel (soot) are deposited, the particles of which, despite preliminary cleaning with several portions of water with an open valve, will still fall into the steam room, worsening the microclimate. Secondly, with this arrangement of the door of the additional chamber with heat storage loading, the kindling of the furnace must be carried out directly in the steam room. In this case, all the smoke until normal draft appears, and this can be very difficult to achieve, especially in wet weather, it will fall into the steam room, settling on the walls, ceiling, shelves. This over time will significantly worsen the microclimate in the steam room. Thirdly, the metal case of the furnace and the furnace with strong heating emits an unpleasant odor of scale, which also worsens the microclimate in the steam room. Fourthly, it is known from practice that for longer operation of metal furnaces steel is used with a thickness of 3 ... 4 mm or more. This design, taking into account double walls and partitions, is metal-intensive, heavy, with a large length of welds. Summing up the high cost of metal, cutting, the cost of welding, assembly, the furnace has low manufacturability and it cannot be installed without a foundation, and installation will be time-consuming. In addition, with strong heating (when heating wood), the stove inflates, the stones in the pockets will slip, unevenly, and when cooled, the stove will not be able to take its original shape. The metal will thin out in some places and the firebox will begin to burn through. And the last one. As you know, the transfer of thermal energy is carried out by thermal conductivity (conduction), convection and radiation. Given that the heat transfer in this design will be very low (the stones touch only a few faces), the side pockets will be heated for a very long time, which also reduces the manufacturability. In addition, the heat storage load will not be exposed to either heat or light radiation, it will not be saturated with the so-called “living” heat of fire, which will not contribute to improving the microclimate in the steam room.

The problem solved by the invention is to improve the microclimate in the steam room and increase manufacturability.

This task is carried out due to the fact that the furnace for the bath contains a housing, a furnace with a door and a blower, a door equipped with a door with a heat storage load placed on the grill, a gas duct and a chimney connected to the chamber and separated from its valve, the furnace body being made of brick and is equipped with two additional flues running in its side and rear walls and connecting the firebox to the chimney, the flues in the chimney are separated by walls and equipped with valves, a chamber with heat storage loading on the solution ke placed over the firebox door chamber is formed in the side wall of the housing, and the door of the furnace and the ash pit located outside the steam room.

The above signs are significant and, in combination, allow us to solve the problem.

The implementation of the furnace body of brick provides sufficient heat capacity of the structure necessary for long-term maintenance of high temperature in the steam room. Given the simplicity of the masonry and the relatively low cost of bricks, an increase in manufacturability is provided, and the absence of metal improves the microclimate in the steam room.

The introduction of two additional flues running in the side and rear walls of the casing and connecting the firebox to the chimney ensures not only the removal of gases emitted during combustion into the chimney and further into the atmosphere, but also the heating of the steam room. In this case, the passage of gases through the heat storage charge is excluded, which helps to improve the microclimate in the steam room.

The separation of the flues in the chimney with the walls and the supply of their valves provides the ability to control the technological processes of heating the furnace and maintaining high temperature in the steam room.

Placing a lattice with a heat storage load above the furnace provides fast and deep heating of the heat storage load with all types of heat transfer, which reduces the preparation time and fuel consumption, i.e. increases manufacturability, and heating by radiation from a flame improves the quality of the steam obtained in the future, which helps to improve the microclimate in the steam room.

The execution of the chamber door in the side wall provides the possibility of arranging the furnace door and the blower in the wall facing the steam room, for example, in the dressing room. This eliminates the ingress of smoke when the furnace is melted into the steam room, which improves the microclimate in it, and the heat generated by the front wall of the case warms up the outdoor room.

The proposed technical solution provides the removal of gases of combustion products from the heat storage charge, its quick and deep heating, uniform and deep heating of the furnace body, eliminates soot settling in the heat storage charge, eliminates the appearance of smoke in the steam room, and improves manufacturability. Thus, the set of features characterizing the claimed object, determines the appearance of such a technical result, which provides a solution to the problem of the proposed technical solution.

The analysis of the prior art shows that the furnace for the bath is not known, which has inherent features identical to all the essential features of this technical solution, which indicates its unknownness and, therefore, novelty. As for the features that distinguish the proposed object from the closest analogues, although some signs are found in other known solutions, however, the influence of these signs on the above technical result is unknown, which allows us to conclude that the proposed solution meets the inventive step.

When carrying out the invention, the presence of the proposed object is really realized, which indicates the industrial applicability of the invention.

Figure 1 shows a General view of the furnace for a bath in isometric projection. Dashed lines show the flues. The second additional duct, laid symmetrically to the first, is not shown; figure 2 is a profile section.

The furnace for the bath (figure 1, 2) contains a housing 1 made of masonry. The furnace 2 with two additional flues 3 and 4 is connected to the chimney 5, also folded of brick. The flues 3 and 4 pass along the side 6 and rear 7 walls of the housing 1 and can be laid both with a slope (Fig. 1) and with rectangular bends of any configuration. The gas duct 8 connects the chimney 5 to the chamber 9. All three gas ducts 3, 4 and 8 in the chimney 5 are equipped with valves 10 and 11, which are designed to control the furnace process, and are separated by the walls 12. The chamber 9 is separated from the furnace 2 by a grill 13, on which through the hole with the door 14 is stacked heat storage load 15. In the front wall of the furnace body 1 there is a loading hole for solid fuel (wood) with a door 16 and a blow hole (blow) 17 with a door 18. Firewood is burned on the grate 19.

The device operates as follows.

The furnace is heated by conventional burning of firewood or any other solid fuel on the grate 13, loaded into the furnace 2 through the hole with the door 16. During the heating of the furnace, the valves 10 are open and gas with harmful combustion products through additional flues 3 and 4 is discharged into the pipe 5 and further into the atmosphere. The valve 11 during the heating of the furnace is closed, thereby preventing the passage of gas and smoke through the heat storage load 15, placed above the flues 3 and 4. During the firewood heating, the heating of the furnace body 1 and heat storage load 15 is carried out by all types of heat transfer. The duration of the preparation period of the steam room for receiving procedures depends on the wall design, the dimensions of the room, the intensity of the furnace process and other factors. After the wood burns out, the gate 10 closes and the gate 11 opens. By periodically opening (during irrigation) and closing the door 14, particles of harmful substances that have fallen on the heat-accumulating charge 15 are washed off with several portions of water, and, given the strong draft in the heated chimney 5, together with the steam through the gas duct 8 are carried into the atmosphere. The valve 11 closes.

The operation of the prototype showed that a furnace heated in a full array maintains a high temperature in the steam room for a long time, and the steam obtained by periodically watering the heat-accumulating charge 15 through an opening in the chamber turns out to be dry, clean with a pleasant spirit of living heat of stones. The furnace is convenient in operation and efficient in operation, technologically advanced and provides improved microclimate and cleanliness in a steam room.
