Description

SAUNA DAY FURNACE AND BATH

The utility model relates to stoves used in saunas, steam baths to create a certain temperature-humidity mode in them.

A well-known stove for baths (autorecor certificate of the USSR No. 1812391, M.Kl; 5: P24S7 / 00, Eg4N7 / 00, bull. 16,1993), containing a container with heat-cumulative loading, container support, electric heaters with current leads and a casing installed around the container with the formation of a through air-heating channel between their side walls, the casing is made below with a bend, and current leads are placed in the hollow support of the container.

A disadvantage of the known furnace is the low efficiency of heating the premises of the sauna or bath.

The closest in technical essence and the achieved result is a heating device comprising a housing made of a number of pipelines of the same cross section connected by means of plates; pipelines are made in a curved shape and are open at the ends and are located in one line parallel to each other. (Patent SM # 4230090, cl. 126-72.1980.)

The room air heating occurs in two planes, and this circumstance allows us to conclude that the heating efficiency of the sauna room is low.

The technical result of creating a utility model is fitfs- improving operational capabilities, increasing the efficiency and reliability of the furnace during operation.

M.C. 6: F24C7 / 00 Rd4ST7 / 00

The technical result is achieved by the fact that in a furnace for a sauna and baths containing a housing with a pressure accumulating load and current leads, the housing is made in the form of two rows of vertically mounted coaxial pipelines arranged in closed loops, which are electric heating elements and fastened by metal frame plates rigidly connected to the supports, to which the pipelines of the inner row of the furnace are made using brackets, made in length shorter than the pipelines of the outer row, dielectric gaskets are installed between pipelines and metal frame plates, as well as between external and internal pipes of coaxial pipelines, the inner pipe of each pipeline in its upper part is made with a bend welded to the external pipe of this pipeline, a grille with a on it a heat storage load, while each pair of adjacent pipelines of the outer row is electrically connected by buses connected to to the running pipes of these pipelines, and to each other, these pairs of pipelines are electrically connected by tires connected to the external pipes of the 2nd pipeline of the first pair and the 1st pipeline of the second pair, then to the external pipes of the 2nd pipeline of the second pair and the 1st pipeline of the third pairs, etc., forming a closed electrical circuit consisting of pipelines of the outer row of the furnace, which, with its midpoints dividing the outer row into two equal parts by the number of pipelines, is connected between two halves of the inner row of the pipe horseflies, connected to current-supplying variable transformer and is electrically connected to each other, similarly to compound vruboprovodov outer row furnace.

An analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed utility model, made it possible to establish that the applicant did not find an analogue “characterized by signs that are identical (identical) to all the essential features of the claimed utility model.

The definition from the list of identified analogues of the prototype "allowed us to identify a set of essential distinguishing features of the claimed utility model with respect to the technical result.

Therefore, "the claimed utility model meets the criterion of novelty1.

The criterion of industrial applicability is confirmed by the fact that the claimed utility model — stoves for saunas and baths — can be successfully used in saunas and baths, with significant increases in energy and material costs in its manufacture, and it has high reliability and electrical safety during operation.

Figure 1 presents a General view of the furnace for saunas and baths; figure 2 is a top view of figure I;

Fig. 3 - connection of pipelines to each other; in Fig.4 is a section along aa of Fig.Z;

in Fig. b is an electrical diagram of the connection of pipelines of the outer and inner rows of the furnace.

The furnace for saunas and baths contains a housing made in the form of two rows "placed one in the other, vertically mounted along closed loops of coaxial pipelines 1 (Fig. I).

rigidly connected with the supports 3. To the supports 3 with the help of brackets 4 are attached pipelines i of the inner row, which are shorter in length than the pipelines I of the outer row. Dielectric gaskets L are installed between the pipelines 1 of the inner and outer rows of the furnace and the metal frame plates 2, since the pipelines act as electric heating elements of the furnace. Each row has an even number of coaxial pipelines 1.

The inner pipe 6 of each coaxial pipe 1 B of its upper part is made with a limb 7 welded to the outer pipe 8 of the pipe 1 (Fig. Y). Above the upper part (figure 2) of the pipeline I of the inner row, a grill 9 is installed, on which, if necessary, a heat storage load is placed

(for example, cobblestone, stones, etc.) (not shown in FIG.).

The current leads 10 (Fig. 5) from a step-down adjustable transformer (for example, a welding machine of the TDM-401 U2 type) installed outside the sauna are connected to the inner pipes 6 of two adjacent pipelines of the inner row II of the furnace. Between the two halves of the inner II row of pipelines electrically connected in series with each other, it is connected by its midpoints A and B. Separating the outer 12 row of pipelines I ne-4i into two equal parts by the number of pipelines, a closed electrical circuit of the outer row of 12 pipelines of the furnace.

The electrical connection of the pipelines of the outer 12 row of the furnace is as follows (figure 5).

Each pair (I, D or F, etc.) of adjacent pipelines I of the outer 12 row is electrically connected by buses connected to the inner b pipes of pipelines I. Between themselves, these pairs (1, P, W, etc.) of pipelines are electrically connected by tires connected to the external 8 pipes (Fig. 5) of the 2nd pipeline of the first

pairs I and 1 of the pipeline of the second pair I. Next - to the external 8 pipes of the Ј-th pipeline of the second pair of I or of the 1st pipeline of the third pair of Zh, etc.

Thus, the electrically series-connected coaxial pipelines I of the outer 12 row of the furnace form a closed electrical circuit.

Similarly, the electrical connection of the coaxial pipelines “being the electric heating elements of the furnace, the inner row AND pipelines through their internal 6 and alternately external 6 pipes of the coaxial pipelines I. The device operates as follows. Electricity from an adjustable (step-down) transformer (for example, a welding machine of the TDM-401U2 type) installed outside the sauna via a conductor (bus) (Fig. 5) from current leads 10 (Fig. 5) is supplied to electric heating elements — coaxial pipelines I “electrical connection which are shown in figure 5. The current passing through the pipelines I heats them. In connection with this, free-convective movement of air from the bottom up through the pipelines of the inner // and outer rows of the furnace occurs, which leads to the heating of the sauna room to the desired temperature.

The heating of the sauna room, with a volume of 20 m3, to T20 ° C at the maximum transformer mode (current 50A) is achieved within I hour 15 minutes. To increase the production of steam, water is sprayed onto a stone heat storage load placed on a grate 9 (Fig. E). The design mode is achieved when the stone load is heated to 200-550 ° C, while the air is heated

to tso ° e.

The proposed furnace for saunas and baths is electrically safe, easy to manufacture and does not require debugging; during operation, the furnace does not burn oxygen, and the implementation of its pipelines and other connecting parts and units made of stainless steel allows us to judge its durability.
