Description

The technical field to which the utility model belongs.

The device relates to the field of heat engineering, in particular to the design of a heat engineering device designed for heating and steam generation, and can be used for equipment of baths and saunas. The level of technology.

A device "Bath furnace" is known (patent for utility model of the Russian Federation No. 52983, class MPK F24B 7/00 (2006.01), publ. 04/27/2006), containing a combustion chamber, which is a steel milling tube, which is mounted in the pipe for the exit of flue gases , to the back side of which a sheet of steel is welded, which is simultaneously the wall of the combustion chamber and the furnace frame, and another sheet of steel is welded to the front part, in which the door for loading fuel is mounted, and a traction power regulator. Along the furnace pipe, on both sides, backing away from it by a certain distance, two more steel sheets are vertically welded, forming a box for laying stones. On the main structure are specially made panels for the distribution of heated air, onto which guide metal plates are welded. The device has a hinged water tank, which can be mounted on either side of the structure.

The disadvantage of this device is the slow heating of the water tank, uneven heating of stones and water in the tank, the cumbersome design of the mounted water tank and guide plates, insufficient protection of the user from hard infrared radiation from the front and back of the device.

The closest solution to the technical nature and the set of essential features, which is adopted as a prototype, is the device "Sauna stove with hot water capacity" (patent for utility model of the Russian Federation No. 47494, IPC classes F24H 1/00 (2000.01), F24H 1/14 ( 2000.01), F24H 1/32 (2000.01), published on 08.27.2005), which is a furnace with a water cylinder located on top and rigidly fixed with it in the form of two cylinders, the inner of which serves as a chimney for the furnace and a heater for water entering outer cylinder.

The device contains a base, a housing, inside which a firebox and a stove are located, a grate or grate for accommodating firewood or wood briquettes, a door for loading fuel, an ash pan, a chimney passing through a hot water tank, an upper nozzle for discharging heated water, and a lower nozzle for pouring cold water.

The disadvantage of this device is the lack of user protection from hard infrared radiation from the furnace, the bulkiness of the design, a significant difference in the speed of heating water and stones over time. Since the release of hot water is carried out through the upper pipe, there is no possibility of operational preparation of a small volume of hot water. Rigid fastening of the hot water tank with the furnace does not allow for the withdrawal of hot or pouring cold water from the right side.

The technical task is to improve the design of the furnace with an additional device for heating water. Disclosure of the essence of the utility model.

The proposed device is a metal housing made in the form of a compact vertically oriented cylinder and acting as a protective casing. Inside the protective casing, in its lower part there is a firebox with a fuel channel protruding above the outer surface of the casing, with a door at its end. The length of the fuel channel allows the furnace to be fired both from the inside and from an adjacent room. Below the fuel channel is an ash channel with an ash drawer. In the upper part of the casing above the furnace there are concentrically located: boiler nozzle, pipe for heat-accumulating material, for example stones (internal heater), a layer of insulating non-combustible material, a tank for heating water. The gap between the protective casing and the internal heater in the upper part of the device is closed with a metal skirt in the form of a truncated cone, the base pointing upward, rigidly fastened to the casing and serving as a stone bowl (decorative outdoor heater). The design of the device provides the optimal ratio of the number of stones and the volume of the tank for water. There are openings for the funnel on the skirt and on the top cover of the water tank. The funnel is inserted into the tank through the hole on the skirt and serves to fill the water.

The presence of insulating material between the internal heater and the tank prevents premature boiling of water, and also eliminates the removal of heat from the stones by the water tank, thereby increasing the heating temperature of the stones in the internal heater.

On the casing of the device, at the top of the furnace, on the sides there are rows of narrow convection holes that are longitudinal in height.

A hot water outlet system to either side of the furnace can be connected to the device’s tank. The water tank can be rotated around its axis, and on the casing of the device from two sides there are caps in the form of a circle or an ellipse formed by narrow slots in the form of arcs, between which narrow strips of metal of at least two are left.

During operation of the device, the plug is squeezed out, and through the hole formed, the hot water outlet system is connected from the desired side.

The design of the device was created on the basis of experiments and is optimal for ensuring the efficiency of the heat transfer process, ensuring the manufacturability of production, fuel economy due to high efficiency and the level of convection of hot air. The simplicity of the design can significantly reduce the installation time of the device, its maintenance and repair.

The design of the device is compact: the height of the furnace together with the water tank is not more than 1500 mm, the overall diameter is not more than 600 mm, the weight without heat storage material is not more than 80 kg; it allows heating a partially filled tank with water and provides protection against hard infrared radiation due to the presence of a protective casing around the furnace.

Effect: improving the design by reducing the size of the furnace and the compact arrangement of its parts, the optimal combination of the amount of heat-accumulating material and the volume of the water tank, the movable connection of the water tank to the main device.

A brief description of the drawings.

The proposed device is illustrated by the drawings shown in FIG. 1, FIG. 2. In FIG. 1 is a side elevational view; FIG. 2 is a sectional view of the front view. The metal protective casing 1 (Fig. 1), made in the form of a cylinder, covers both the upper and lower parts of the device. From the lower part of the casing 1, where the furnace of the furnace 2 is located (Fig. 2), a fuel channel 3 (Fig. 1) with a door 4 (Fig. 1) at its end protrudes, and an ash channel with an ash box 5 ( Fig. 1). Air convection between the furnace 2 and the protective casing 1 is carried out through the narrow convection openings 6 (longitudinal in height) (Fig. 1), as well as through the gap between the casing 1 and the top plate of the furnace 7 (Fig. 2). In the center of the device there is a boiler pipe 8 (Fig. 2), on which a chimney is installed to remove flue gases from the furnace of the furnace. Between the protective casing 1 and the outer surface of the inner heater 9 (Fig. 2) is a tank 10 (Fig. 2), designed to heat water. Between the outer surface of the inner heater 9 and the water tank 10 is a layer of insulating non-combustible material 11 (Fig. 2). In the upper part of the device, the gap between the protective casing 1 and the inner heater 9 is closed by a metal skirt 12 (Fig. 2) in the form of a truncated cone directed upward, rigidly fastened to the casing 1 and serving as a bowl for stones forming an outer heater. In the metal skirt 12 in the upper part of the water tank 10 there are holes for installing a funnel for filling the water 13 (Fig. 2). On the protective casing 1 from two sides are two plugs 14 (Fig. 1), which allow you to connect to the water tank 10 a hot water outlet system from one of the selected sides. Implementation of a utility model.

The device operates as follows. As a result of fuel combustion in the furnace 2, water is heated in the tank 10, as well as heat-accumulating material in the internal heater 9, the external heater is a decorative element and does not significantly heat up. The device can operate in intense combustion during kindling and temperature selection and in an economical mode during normal operation.

Through the boiler pipe 8, hot flue gases pass through the inner heater 9, and, due to the fact that the outer surface of the inner heater is protected from the water tank by a layer of insulating non-combustible material 11 and heat transfer to the water tank 10 is practically not carried out, the inner heater 9 forms a powerful steam generator in which the stones can heat up to 400 ° C and above. The water tank 10 performs heat removal only from the upper convection plate 7 of the furnace furnace. All this allows you to combine the high temperature in the inner heater 9 (to obtain finely dispersed "light" steam) and eliminates premature boiling of water in the tank 10. The casing 1 and the water tank 10 do not have a rigid connection with the furnace, the tank 10 is supported and heated only from the top firebox plates 7. When dismantling the casing 1, the tank 10 can be turned in the necessary (right or left) side to withdraw hot water.

The protective cover 1 protects the user from hard infrared radiation. The compact cylindrical shape of the device saves steam room and fuel, requires a short heating time of the room and the device, provides ease of transportation and operation. A rotating water tank allows you to improve the functionality of the device for supplying water to the tank and removing water in any quantity.
