Description

The technical field to which the utility model belongs.

The utility model relates to the construction of stoves when equipping baths. The utility model relates to heat engineering, namely to household bath stoves, and is intended for heating a room, heating water and generating steam.

State of the art

In the case of well-known sauna stoves, the following are not provided: the durability of the combustion unit, the absence of rust entering the steam room, proper shielding from hard infrared radiation. For example, there is a known stove for a bath (RU 2598274 C1), which includes a metal body with a firebox, an ash pan, a grate, a chimney and a stove made in the form of a metal container isolated from the firebox, filled with lumpy heat-consuming material, equipped with a pipe for supplying water to the layer heat-capacious material and a door for steam outlet, and the branch pipe is connected through a dropper with a water tank. A technical problem is the creation of a device design that avoids thermal deformation of the metal and thereby extends the life of the furnace, increases the heating rate of the steam room and its fire safety, as well as the comfort of receiving procedures when supplying steam.

Disclosure of the essence of the utility model

The purpose of the utility model is to create such a design for a sauna stove, which will ensure a long service life of the combustion apparatus at an increased heating rate of the steam room due to controlled convection, the presence of controlled convection allows you to connect a duct system to the furnace, with which you can heat several rooms, no rust entering the steam room, fastening a closed stove allows you to significantly relieve the load from the metal (due to the fact that it is welded only in one place, but the entire weight of the stove falls on the heat transfer plates) proper shielding from hard infrared radiation, the presence of facing plates and facing bricks allows you to quickly replace it in case of damage, the presence of a grid detached from the cladding holding stones (which cannot destroy the cladding in case of thermal destruction). The system of fastening the plates to the metal frame allows the cladding to be rigidly fixed, but at the same time not to destroy it during thermal expansion. The stove contains a chimney pipe 1, a funnel for water supply 2, turning into a corrugated pipe with transverse slots for dispersing water, a stainless steel mesh 3. A closed stove with a convex bottom 4 is attached to the stove body 6 by means of heat transfer plates 5. Fuel channel 7 and cast-iron door of the firebox 8 attached to the furnace body from the side. Under them there is an ash box 9 with a grate 15. In the lower part of the furnace body there is a protective casing 10, as well as furnace supports 11. There is a strengthening of the combustion chamber 12. In the upper part of the closed heater there is a channel for laying stones 13, as well as a hatch for cleaning the chimney 14.

Implementation of the utility model

To solve the problem, a furnace design is proposed, in which the closed stove of the stove is made of stainless steel, which significantly extends its service life, and in order to avoid metal deformation, the closed stove is welded to the furnace body only in the upper part by a branch pipe through which loading and unloading occurs stones, as well as the release of steam. The lower part of the stove has a convex shape and is supported by four plates that are welded into the body through. In addition to the fact that these plates hold the stove, which significantly relieves stress from the metal, they are heat transfer plates that transfer heat both to the closed stove and to the outside. Since they are located in the corners of the furnace lining, the air in the formed channels heats up much faster and faster heating of the steam room is provided. The lower part of the furnace has bevels at 45 degrees, which does not allow coal to accumulate on the metal surface, and it rolls into the ash pan. Additional protection in case of metal burnout - underneath there is a furnace body, 6 mm thick boiler steel. Thus, the service life of the combustion unit is increased several times, since this is one of the most thermally loaded places in the furnace. The furnace has a very wide ash pan, which is much larger than the grate, and this greatly simplifies the cleaning of the furnace, since the ash does not wake up and is an additional element of fire safety. The funnel for supplying water to the heater has an original shape and design. The platform, which covers the closed heater, has several useful functions, it does not allow water to splash back from the closed heater in case of excessive flow. But at the same time, its not tight fit allows the steam-air mixture to escape freely and emit a characteristic surf sound. A narrow tube in the funnel launches dosed water into the closed stove, which ensures a very even flow of the steam-air mixture into the steam room, and the presence of a stainless steel mesh in the tube heats the water before it enters the stove, which does not allow the stones and the stove body to cool too much, and means it removes unnecessary stress from stones and metal and allows you to quickly restore the temperature in the stove, this makes it possible to take procedures more evenly and to more people. All elements of the closed heater are made of stainless steel, which prevents rust from entering the steam room along with steam. A brick lining of the oven is also used, which is unique in that it allows the placement of convection channels where necessary, taking into account the configuration of the paired space. Convection in this oven is controlled by a plug that can be opened to activate the convective flow or close and stop it. The mass of the stove and stone is very serious, but thanks to its correct placement, this stove can be installed in mobile and transportable baths, and the brickwork can be mounted after the bath is installed in place. The presence of a large volume of stone dries out the bath, even if the stove is no longer heated. It also allows you to create a lot of regimes in the bath, both dry (Finnish sauna) and humid atmosphere (light brown bath), and, subject to certain rules, and hammam. One of the differences from the closest analogs in addition is that it is used that allows such an implementation to be carried out.

Although the present utility model has been described with reference to a specific embodiment of the present utility model, the present utility model is not limited to this embodiment. Those skilled in the art will appreciate that the following modifications are possible. The stove can be lined with soapstone bricks, such a lining completely removes infrared radiation from the stove. Another option is also possible: a rigid and durable metal frame, gives reliability and durability, and facing plates-screens made of porcelain stoneware, give the stove an excellent look, additional heat capacity, excellent strength characteristics and shielding from hard PC radiation, as well as maintainability. Not an unimportant moment, this is the system of fastening porcelain stoneware slabs to metal, since metal and stone have different linear expansion, the slabs are not rigidly attached and gaps are left to compensate for the expansions. A simple but reliable system for fixing the plates allows you to quickly assemble and disassemble the stove, which is very important in mobile baths, and in any other baths. Another advantage of this cladding is its adjustable convection and the ability to heat adjacent rooms.

In addition, instead of lining with bricks or facing slabs, it is possible to use a mesh that is filled with chipped stone, and this design significantly reduces the cost of the furnace. The grid (with a cross section of 50 mm and a bar thickness of 5 mm) on a metal frame (30 * 30 * 2 mm) does not allow the filled-in chipped stone (between the grid and the furnace) to break or deform the outer plate. Filling the chipped-sawn stone greatly reduces the cost of the structure, but at the same time there remains an excellent reserve of stone mass, which is very good for bath procedures and drying the bath.

Industrial applicability

This utility model is proposed for household and professional use for heating baths.
