The date of birth of the sauna is not known, but it is believed that the so-called "warm up" in the sauna. Smoke sauna was already known during the Stone Age. At first, Saimo used to be nature caves and later land caves, huts and log buildings. The Iron Age saunas were pits raised with corner log walls. Today, there are only a few local museums and 10 private saunas for some big sauna lovers. A lot of commercial products and inventions have been made around the sauna. There are many books and publications about the sauna and its history.

Today, there are many different types of sauna available: single-heated, continuous-heating, electric sauna, smoke sauna, etc. At its best, bathing creates moments of enjoyment that have created organizations and clubs that are dedicated to maintaining and developing sauna culture. The ventilation of the sauna, the ionic content of the steam and air, the humidity and heat conditions, etc. have been studied extensively, and various technical instruments are used to measure them.

20 •. * ·: Saunas with a fireplace stove are divided into two groups: single-heated and continuous: '* heated. Too hot, especially the metal surfaces of the heater, are known to give the room so-called.

· '*' Bad ions. Therefore, the so-called "one-time" sauna. the aftermath conditions are generally considered to be 'best'. Disposable heaters have such a large amount of stones and heat capacity that, even though the heaters are no longer hot, it is still possible to cast the steam and produce a pleasant afterglow.

, * ·, Indoor heated or smoke sauna is considered the most enjoyable type of sauna. Due to the risk of fire, the amount of stones in the smoke sauna stove must be so large that the burning of the trees takes place entirely beneath the cobblestone layers. If flames were to flare through the rocks, fire would be inevitable in the log structures commonly used in smoke saunas. Smoke saunas have a rock; 'Largest heater in volume and therefore the largest volume of smoke saunas. The large amount of stone and the large volume of the sauna provide pleasant steam conditions. The large amount of 2 113837 stones also allows the steam to be thrown on already slightly cooled stones. It is well known that the cooler rocks still make a good steam, the better they feel.

However, you need to be able to throw the steam so much that you initially feel the burning heat. The burning heat of the baths for too long is perceived as unpleasant. The large volume of the smoke baths 5 is capable of reducing the burning heat moment at the beginning of the steam discharge to a pleasantly short. In saunas that are too small, especially when the sauna stones are usually hot, it seems too long to burn the steam when casting the steam. The thing that would be enjoyed for a moment becomes painful. Too short a hot period is reduced by effectively changing the sauna air to quickly reach a too-cold 10 position and having to throw the steam almost immediately. Perhaps the most attention in research and development of sauna conditions is precisely the development of ventilation. It is known that there is no need to constantly steam in the smoke sauna. Due to the volume, the entire amount of air in the sauna does not change completely immediately after the steam has been cast, so after the hot start of the hot steam, it is longer to feel pleasantly warm. Of course, the large amount of stones in the stove also radiates a pleasant warmth between the throws of the steam, and the steam sauna boards may have a long conversation with bath mates while enjoying the steam.

The difficulties of a smoke sauna, or a heated sauna, are known. Fire hazard is a dreaded feature of 20 smoke saunas. Avoid sooting and fire risk by arranging suitable wood for heating the stove. Alder wood is considered to be a paraffin • •: '* Shark firewood for its fine aroma and clean burning. It is necessary to heat the smoke sauna * · '·' so long that the rigs become hot. When the stove is forced to be large, the heat limit of the sauna is high. The smoke sauna room must therefore be made high if it is desired to have the toes above the stone surface and the thermal limit when sitting on rugs.

: _ The problem with single-heated saunas before this oven was invented has been the relatively short period of ideal sauna conditions and especially the soils containing soot in the beginning. In a traditional smoke sauna stove you have to keep the fire under control and the stove-30's water soot. In the beginning you have to throw lots of so-called. soot to clean the rocks.

Since the structures of the furnace sauna according to the invention store the heat of the combustion gases in themselves> * · and withstand high temperatures, it is recommended to heat the stove at such a high temperature that the stones of the stove are clean from the very first steam. The heat in the heat-storing sauna stove 3 113837 takes place as efficiently as possible and still takes place above the sauna stones even in the sauna room. The heating time is reduced because the maximum amount of heat is obtained from the wood to be burned. When heating known smoke saunas, a large mixture of unburned flue gases rises from their openings. In the oven sauna prototype-5 stoves, flue gas has been observed to vibrate almost clear when clean. Selected alder woods are not needed to achieve the ideal steam conditions, as in a smoke sauna, but the fireplace can also be easily heated with conifers.

The main principle of the sauna sauna invention is the heat-storing stone ceiling and walls 10, whose heat capacity and the power of the heater are designed to achieve the longest possible ideal sauna time. The stove's firebox door is outside the sauna area. During heating, it is so hot in Saimaa that it would be difficult to add trees during the indoor season.

The hot flue gases burning on the stove rise on the other side of the chimney to the chimney leaving the ceiling, while heating the wall and ceiling structures. Based on prototype tests, 15 units have been developed in which massive roof and wall structures warm to about 60 degrees Celsius, the ideal temperature. The structures smoothly cut off the early heat of 100 degree steam and shine with pleasant warmth, even though ventilation is mimicked. Steam sauna baths are ideal for the entire record-breaking sauna time, which is equivalent to 20 burns of a traditional smoke sauna. In the prototype tests, ideal steam conditions were achieved for another 24 hours after heating. Because high draft can be maintained throughout the burn, the soot limit and • · · 's * hot limit are high above the rafters. Also, due to the faster heating time of known smoke saunas «> · laude surfaces do not have too much time to heat. Heat storage oven heater. , nan boards do not become uncomfortably hot during heating.

Dense stone materials are not suitable for sauna surface structures due to burning surface heat and condensation causing moist steam air. As a result, the surfaces of smoke sauna rooms are typically wood. Some of the walls of the open pit saunas have been built with lightweight stone blocks, but the ceilings are also made of wood. In the big old,.! 30 public saunas and more recent steam saunas use stone surfaces for their durability; and maintenance. Thanks to its large volume, height and wooden handrail structures, the steam conditions have been tolerated. For smaller private saunas, dense stone materials are unsuitable.

There are attempts to solve the problems of a smoke sauna, for example, in FI patent 81492. The patent only achieves fire resistance properties by using heat insulating stone materials, but the heat storage property of the structures in question. the invention does not include. The heat capacity of the heat insulating materials 5 is poor, which requires that the kilns must be large, as with traditional smoke saunas, in order to have a sufficiently long bathing time. The smoke sauna still had to be made spacious and high in order for the steam conditions to be good. The invention has not led to manufacture.

Efforts have also been made to solve the problems of a smoke sauna in utility model publications 5073 10 and 4458. Complex arrangements have not gained commercial popularity.

In order to keep the sauna heat for as long as possible, the sauna has traditionally been made very well insulated. The small stone surfaces of the heat-insulated sauna, such as the wall masonry used to protect the heaters, become hot burners during heating. Therefore, prior to the present invention, stone structures having a heat capacity have not been used to improve the properties of the sauna. When the roof and walls are made of stone and the thickness is properly dimensioned for the effective heat capacity, the heat-retaining material is present in such a way that the surface temperature of the structures does not rise to the scorching heat. Suitable surface temperatures for concrete surfaces cast from a moist concrete mass have been found to be approximately 60 degrees Celsius in a prototype 20 oven oven. In the prototype sauna sauna, the roof and wall structures of the • • * · '. * Heater above the heater have a weight of approximately 10,000 • kg, a sauna volume of 19 m3, a sauna heater weight of 320 kg and a heater weight • 1400. kg. Under normal heating, the temperature of the sauna stones rises to 300-350 and ♦ · ·, ·. . road surface temperature to 60 degrees Celsius. With these values, ideal sauna conditions were achieved for even longer than 24 hours.

Thermal insulation * of sauna structures with a continuously heated electric or wood stove. Exercise is important for maintaining and maintaining the heat of the steam. In smoke saunas, heat is reserved for a large amount of stone in the heater. At the beginning of the sauna, when the rocks are at their hottest, the steam ... 30 is too hot. Smoke sauna baths are at their best towards the end. The greater-,; pi is the amount of stone in the heater, the longer the ideal sauna temperature is stretched. Traditional ;,. that is why efforts have been made to maintain this ideal sauna temperature by building smoke saunas out of highly heat-insulating materials. The heat insulating materials have a poor thermal capacity. The idea of an oven sauna is based on the use of structures with heat capacity.

The structures seem to continue the amount of sauna stones and heat is stored in the sauna structures. With a smaller amount of sauna stones in the sauna, the heat-storing structures in the oven can achieve an ideal sauna temperature many times longer than a traditional smoke sauna.

The short sauna times of smoke saunas make them unsuitable for long-term spas or other public saunas. The sauna is well suited as a public sauna for spas and other buildings due to its long steam time and fire resistant construction.

10 Despite the enjoyment of the smoke sauna, it has not been possible to develop it into a successful market product due to known difficulties.

Too smooth roof and wall surfaces reflect the steam as an uncomfortably hot breath reflection on the bather's skin. Various steam controls have been developed for the saunas, 15 to provide a smooth and comfortable steam. The vaulted curved ceiling of the oven makes the sauna soft and even.

Because the invention is able to eliminate the known drawbacks of a smoke sauna, the kek-20 has been renamed for its purity and heat-storage properties: • new. 'Nisauna. It is also possible to make the sauna sauna small in size, as heat accumulates in the • wall and ceiling structures.

Municipal building regulations nowadays require that buildings are not blatantly visible on waterways. The underground slope sauna sauna is beautifully landscaped. A heat-insulated furnace sauna can also be constructed normally on the ground, whereby the thermal insulation is lined with known building materials such as a log structure. Due to the stone material, the new-5 whirlpool sauna is shaped like a large heat-storing oven, which does not accidentally burn like log-fired smoke saunas. The stone structure allows a higher temperature when heated and the flue gas flow rates are higher, which keeps the sauna cleaner from soot despite the smoke aromas.

10 Both the wall and ceiling structures of the oven sauna are porous stone blocks or elements that absorb the moisture of the steam air during bathing so that no disturbing condensation and dripping occurs. The same porous material dries efficiently during heating and is not damaged in the long damp Odessa. The automatic humidity and heat regulation of the structures make the bathing conditions even more pleasant for a long time.

An oven sauna allows you to build a small, soot-free, heated in-house sauna, even on a normal-sized detached house plot. When the heating of the heater is tracked from the outside of the oven sauna and a fire resistant door is used, the smoke sauna 20 can also be located in connection with the rest of the building.

Ra- ", in other types of saunas, can be heated, for example, by electric resistors or water circulation pipes such as underfloor heating.
