Description
[0001] Method and system for introducing smoke into a sauna room of a sauna
[0002] TECHNICAL FIELD
[0003] The present invention relates to a method and system for introducing smoke into the sauna room of a sauna. Specifically, the present invention belongs to the field of the construction of saunas, more specifically of sauna stoves, and relates to connecting a smoke generator and sauna stove to achieve a sauna experience characteristic to a smoke sauna.
[0004] BACKGROUND ART
[0005] A traditional known smoke sauna is generally heated for relatively long time before using it and all heat needed for staying in the sauna is stored in the stones of a sauna stove. A traditional smoke sauna cannot be heated while staying in the sauna, because a smoke sauna has no chimney and the entire smoke generated during heating is released into the sauna room.
[0006] Japanese patent application JP2000140063A (published 23 / 05 / 2000) discloses a sauna heating unit equipped with an aroma generation device, which is located in the upper part of the heating unit in the steam room, and through which heated water vapor is routed. This device cannot be used for generating smoke for a smoke sauna.
[0007] DISCLOSURE OF THE INVENTION
[0008] The objective and advantage of the present invention is to enable using and enjoying smoke sauna faster and longer, as a sauna with such system can be heated while staying in the sauna. Therefore, there is no need for a large mass of stones and the present invention enables achieving an experience similar to a smoke sauna with considerably less time. An automatic sauna heating system can also be used with this solution, because automatics can be added to the smoke generator and the sauna stove. The smoke generator may be located under, adjacent, or inside the sauna room.
[0009] According to the present invention, the generated smoke is routed into the sauna room before and / or during the heating of the sauna. Before achieving the required temperature in the sauna room, the smoke generator is switched off and the sauna room is ventilated. After that, it is possible to start enjoying an experience similar to a smoke sauna. As the present invention enables continuing heating the sauna with a sauna stove, the period of use of the sauna room is unlimited. The time of use of the smoke generator and the possibility to use chips of various timber species provides to the user a suitable aroma and its intensity in the present invention.
[0010] In the method of the invention for introducing smoke into the sauna room of a sauna, smoke is generated in a smoke generator; from the smoke generator, the smoke is routed to the sauna stove; and from the sauna stove, the smoke is routed into the sauna room. Smoke is ventilated out of the sauna room with an exhaust fan, which is installed in an exhaust ventilation opening.
[0011] In the method of the invention, smoke is routed from the smoke generator into the sauna room through the stones of the sauna stove.
[0012] In the method of the invention, a system is used for routing the smoke into the sauna room of the sauna, comprising a sauna stove and a smoke generator, the smoke generated by which is routed into the sauna room through the sauna stove.
[0013] The present invention provides a system for introducing smoke into the sauna room of a sauna, where the system comprises a sauna stove and a smoke generator, the smoke generated by which is routed into the sauna room through the sauna stove.
[0014] According to the first embodiment, the smoke generator of the system is intended for installation outside the sauna room.
[0015] According to the second embodiment, the smoke generator of the system is intended for installation in the sauna room.

[0025] BRIEF DESCRIPTION OF DRAWINGS
[0026] The invention is described below with reference to the appended schematic figures, where:
[0027] Figure 1 illustrates a section of a sauna room where the sauna stove is located and into which the smoke pipe of the smoke generator is routed;
[0028] Figures 2, 3, and 4 illustrate the embodiments of the casings of the sauna stove where the inlet of the smoke pipe is from a side, from under the bottom, and laterally from under the bottom, respectively.
[0029] MODES FOR CARRYING OUT THE INVENTION
[0030] For the sake of clarity, similar details and elements on different figures have the same reference numbers.
[0031] Figure 1 illustrates sauna 1 , comprising a sauna room 2, a sauna platform 3, a sauna stove 4, a smoke generator 5, a fresh air inlet opening 6, an exhaust ventilation opening 7, a smoke pipe 8, and an exhaust fan 9.
[0032] In order to achieve the aroma of a smoke sauna, it is necessary to operate the smoke generator 5 before or during a heating of the sauna, and to route the smoke generated by the smoke generator through the smoke pipe 8 to the vicinity of the sauna stove 4, so that smoke would move through the sauna stove 4 into the sauna room.
[0033] For using the smoke sauna 1 with a smoke generator, the smoke generated by the smoke generator 5 shall be removed from the sauna room 2 before use. For this purpose, a fresh air inlet opening 6 and an exhaust ventilation opening 7 are needed, whereby an exhaust fan 9 is attached to the exhaust ventilation opening 7, which together ensure the ventilation of the sauna room 2 and a sufficient oxygen level in the sauna room 2.
[0034] Many people want to enjoy a smoke sauna, but the use of a traditional smoke sauna is inconvenient and requires much preparation. Furthermore, the time of use of a traditional smoke sauna is limited. The present invention makes using a sauna easier and the invention can be used as conveniently as a traditional Finnish sauna, without losing the characteristic aroma and steam of a smoke sauna. The possibility to use automatic heating, smoke generation, and ventilation makes the smoke sauna 1 with a smoke generator much more comfortable.
[0035] With the present invention, the type of the sauna stove is not important, i.e. if it is a electric sauna stover or a sauna stove operating with solid fuel (wood).
[0036] Figure 2 illustrates casing 4 of the sauna stove, where inlet 10 of the casing for connecting the outlet of smoke pipe 8 is located on the side of casing 4.
[0037] Figures 3 and 4 illustrate casing 4 of the sauna stove, where the inlet 10 of the casing for connecting the outlet of smoke pipe 8 is located under the bottom of the casing 4. In the embodiment illustrated on figure 4, a 90-degree bend can be connected to the inlet 10 located under the bottom of the casing 4.
[0038] As the interior construction of the sauna stove is not different from the constructions of common sauna stoves, it is not illustrated in the context of the present invention.
[0039] Prefabricated smoke generators intended, for example, for the smoking cabinets of meat and other foodstuff can also be used with the present invention. An example of this smoke generator is a fully automatic stainless steel smoke generator GDS-01 from Borniak Ltd. (https: / / borniak.co.uk / smoke-generator-stainless-steel-gds- 01.html). In these generators, smoke is generated using wood chips or chopped wood.
[0040] The method and the system of the invention can also be applied in the case of existing sauna stoves with an opening or openings in the lower part of the casing of the sauna stove, where the smoke exiting from the outlet of the smoke pipe 8 of the smoke generator 5 can be routed to the sauna stove, but which are not specially intended for connecting the mentioned outlet.
