JP 2013-234855 A

  The gas combustion heater disclosed in Patent Document 1 can release steam from the heater itself into the sauna room without installing a separate steam generation facility by installing a humidifier in the heat radiation tube. . However, a large amount of steam cannot be generated from the humidifier at a stretch, and it cannot be used as a steam generator for a roulau sauna (Finnish sauna) that envelops the body with a large amount of hot airflow (heat wave). The temperature of the sauna room varies depending on the type, and is used in a wide temperature range of 60 to 100 ° C.

  It is an object of the present invention to heat a sauna room to a temperature suitable for a roulu sauna and to release and fill a large amount of high-temperature steam in a short time into a sauna room to make the sauna room a hot air flow environment suitable for a roulu sauna. The object is to provide a roulyu sauna system. Another object of the present invention is to provide a lowry sauna system that can generate a large amount of high-temperature steam a plurality of times in a short time and can quickly make a sauna room into a lowry sauna.

  The premise of the present invention for solving the above problems is a roux sauna system that uses a combustion gas at a predetermined temperature to make a sauna room a roux sauna.

  The feature of the present invention based on the above premise is that the Roulyu sauna system is formed of a heater device that radiates heat of the combustion gas into the sauna chamber, and a steam generator that generates high-temperature steam using the heat of the combustion gas. The apparatus is a burner that produces combustion gas, a heat first radiation pipe that is connected to the burner and dissipates the heat of the combustion gas into the sauna chamber, and flows the combustion gas into the steam generator, and the combustion gas that has flowed out of the steam generator A heat second radiant tube that radiates the heat of the heat into the sauna room, an exhaust port that is connected to the heat second radiant tube and exhausts the combustion gas to the outside air, and a fan that flows the combustion gas from the burner toward the exhaust port The steam generator has a casing that is long in the vertical direction, a lid that can open and close the top opening of the casing, and a compound that is housed in the casing and heated to high temperature by combustion gas. A sauna stone, a combustion gas inlet formed at the top of the casing and connected to the heat first radiant tube, and a combustion gas outlet formed at the bottom of the casing and connected to the heat second radiant tube. In the steam generator, the combustion gas is allowed to flow from the top to the bottom of the casing while the top opening of the casing is closed, and the lid is opened to open the top opening of the casing, and then is accommodated inside the casing from the top opening. By injecting water into these sauna stones, a large amount of high-temperature steam is released from the top opening at once into the sauna room.

  As an example of the present invention, the first heat radiation tube of the heater device is accommodated in a housing having a predetermined volume and extends in a meandering manner in the vertical direction, and the combustion gas flow of the casing extends to the outside of the housing. A first exposed portion connected to the inlet, and a second radiating tube of the heater device extends to the outside of the housing and is connected to the combustion gas outlet of the casing; A second undulation portion extending in a meandering manner.

  As another example of the present invention, in the steam generator, in a state where the lid is closed and the top opening of the casing is closed, the combustion gas is caused to flow from the top to the bottom of the casing, so that the sauna stone located at the top The sauna stones are heated to a high temperature towards the sauna stones located at the bottom.

  As another example of the present invention, in the steam generator, after the release of the high-temperature steam from the top opening of the casing is finished, the lid is closed to close the top opening of the casing, and the combustion gas is directed from the top to the bottom of the casing. These sauna stones are reheated by flowing them, and in reheating these sauna stones, the sauna stone located at the top of the casing is heated before the sauna stone located in the middle part of the casing, The sauna stone located at is heated before the sauna stone located at the bottom of the casing.

  As another example of the present invention, the Roury Sauna system includes a combustion gas bypass pipe connected to the first exposed portion of the first heat radiation tube and the second exposed portion of the second heat radiation tube. When the lid is opened and the top opening of the casing is opened, the combustion gas bypass pipe is opened, the first exposed portion extending between the combustion gas inlet and the combustion gas bypass pipe is closed, and the combustion gas outlet The second exposed portion extending between the combustion gas bypass pipe and the combustion gas bypass pipe is closed, the inflow of the combustion gas from the top of the casing into the casing is blocked, and the combustion gas passes from the first exposed section through the bypass pipe to the second exposed section. Flow into.

  As another example of the present invention, in the Ryuyu Sauna system, when the lid is closed and the top opening of the casing is closed, the combustion gas bypass pipe is closed and the first exposure extending between the combustion gas inlet and the combustion gas bypass pipe is provided. And the second exposed portion extending between the combustion gas outlet and the combustion gas bypass pipe is opened, and the combustion gas flows from the top to the bottom of the casing.

  According to the Roulyu sauna system according to the present invention, it is formed of a heater device that radiates the heat of combustion gas into the sauna chamber and a steam generator that releases high-temperature steam into the sauna chamber using the heat of the combustion gas. Therefore, by releasing the heat of the combustion gas from the first heat radiation tube and the second heat radiation tube of the heater device, the sauna room can be heated to a temperature suitable for a lowry sauna, and a large amount of high temperature is generated from the steam generator. By generating steam, a large amount of high-temperature steam can be discharged and filled in the sauna room, and the sauna room can be quickly brought into a hot air flow environment suitable for a lowry sauna. The Roulyu sauna system allows combustion gas to flow from the top to the bottom of the casing while the top opening of the casing is closed, and the sauna stone contained in the casing is immediately heated, so that a large amount of high-temperature steam is generated from the steam generator. It can be generated a plurality of times in a short time, and the sauna room can be quickly made into a lowry sauna. The Roury Sauna system allows combustion gas to flow from the top to the bottom of the steam generator, so that the sauna stone located at the top is heated to a high temperature. It can be instantly vaporized and a large amount of high temperature steam can be released from the steam generator into the sauna room at once.

  A first heat radiation tube of the heater device is housed in a housing of a predetermined volume and has a first undulation portion extending in a meandering manner in a vertical direction and a first exposed portion connected to a combustion gas inlet of the casing. A low sauna system having a second exposed portion where the second radiant tube is connected to the combustion gas outlet of the casing and a second undulating portion accommodated in the housing and extending in a vertical manner meandering is a first of the heat first radiant tube. By radiating the heat of the combustion gas from the undulation part and the second undulation part of the heat second radiant tube, the sauna chamber can be heated to a temperature suitable for the lowry sauna, and the combustion gas is transferred from the first exposed part to the steam generator. A large amount of high-temperature steam can be generated from the steam generator by heating the sauna stone by feeding and pouring water into the sauna stone. The Roury Sauna system has a sauna room heated to a temperature suitable for the Roury Sauna by heat radiated from the first undulation portion of the heat first radiant tube and the second undulation portion of the heat second radiant tube, and from the steam generator. By generating a large amount of high-temperature steam and releasing and filling a large amount of high-temperature steam in the sauna room, the sauna room can be quickly made into a low-rise sauna.

  With the lid of the steam generator closed and the top opening of the casing closed, the combustion gas flows from the top to the bottom of the casing, so that the sauna stone located at the top moves toward the sauna stone located at the bottom. The Roury Sauna system for heating these sauna stones to a predetermined temperature allows the combustion of the combustion gas from the top to the bottom of the steam generator with the top opening of the casing closed, so that the sauna stone located at the top becomes hot. By heating and pouring water into the sauna stones located at the top after opening the top opening, water is instantly vaporized in the sauna stones, and a large amount of high-temperature steam can be discharged from the steam generator into the sauna room at once.

  After the release of the high temperature steam from the top opening of the casing is finished, the lid is closed to close the top opening of the casing, and the sauna stone is reheated by flowing the combustion gas from the top to the bottom of the casing. When the sauna system pours water from the top opening and generates high-temperature steam, the temperature of the sauna stone located at the top first decreases, but the combustion gas flows from the top to the bottom of the casing to the top. The sauna stone located is heated quickly, and the sauna stone located in the middle and bottom is quickly heated. Therefore, the generation cycle of high-temperature steam in the steam generator can be shortened. Can be generated a plurality of times in a short time.

A combustion gas bypass pipe connected to the first exposed portion of the thermal first radiant tube and the second exposed portion of the thermal second radiant tube, the combustion gas bypass when the lid is opened to open the top opening of the casing The pipe is opened, the first exposed part extending between the combustion gas inlet and the combustion gas bypass pipe is closed, and the second exposed part extending between the combustion gas outlet and the combustion gas bypass pipe is closed. The inflow of combustion gas from the top of the casing to the inside of the casing is blocked, and the combustion gas flows from the first exposed portion through the bypass pipe to the second exposed portion.
For example, when the top opening of the casing is opened in a state where no bypass pipe is installed, air in the sauna room enters the inside of the casing from the top opening and air enters the second heat radiation pipe, and the first heat radiation pipe. When the top opening of the casing is opened by installing a bypass pipe, the combustion gas cannot flow smoothly from the burner toward the exhaust port. Since the combustion gas flows into the bypass pipe, air does not enter the second heat radiation pipe, the first heat radiation pipe and the burner can be held at a negative pressure, and the combustion gas is transferred from the burner to the exhaust port. It can flow smoothly. Further, when the top opening of the casing is opened without the bypass pipe being installed, the generated high-temperature steam is discharged from the exhaust port through the heat second radiation pipe to the outside of the sauna room. When the top opening of the casing is opened, the combustion gas flows into the bypass pipe, and the combustion gas does not flow from the top to the bottom of the casing. It can be reliably discharged from the opening into the sauna room. Further, when air enters the casing, the air is mixed with the combustion gas and the thermal energy of the combustion gas is reduced, and infrared radiation having high thermal energy cannot be emitted from the heat second radiation tube. Since the combustion gas flows into the second exposed portion through the bypass pipe during the opening, it is possible to prevent a decrease in the thermal energy of the combustion gas during the opening of the top opening, and sufficient heat is supplied via the heat second radiation tube. Infrared rays having energy can be radiated into the sauna room, and the temperature of the sauna room can be heated and maintained at a temperature suitable for the roulw sauna. In some cases, the combustion gas leaks from the top opening while the top opening is open and an unexpected accident may occur due to the combustion gas. Can prevent unforeseen accidents.

  When closing the lid and closing the top opening of the casing, the combustion gas bypass pipe is closed, the first exposed portion extending between the combustion gas inlet and the bypass pipe is opened, and the combustion gas outlet and bypass When the second exposed part extending between the pipes is opened and the combustion gas flows from the top to the bottom of the casing, the roll sauna system is configured so that the combustion gas is immediately discharged from the top of the casing when the top opening of the casing is closed. It can flow toward the bottom and the sauna stone can be reheated quickly. In the Roury Sauna system, when water is injected from the top opening to generate high-temperature steam, the temperature of the sauna stone located at the top decreases first, but the combustion gas flows from the top to the bottom of the casing. Because the sauna stone located at the top is heated quickly, and the sauna stone located at the middle and bottom is quickly heated, the generation cycle of high-temperature steam in the steam generator can be shortened, and steam generation A large amount of high-temperature steam can be generated several times in a short time from the apparatus.

After reheating the sauna stones 34, the lid 33 is opened to open the top opening 32 of the casing 31, and water is poured into the sauna stones 34 accommodated in the accommodation space 45 of the casing 31 from the top opening 32. A large amount of high-temperature steam can be discharged again from the opening 32 into the sauna room 11.

  The room of the sauna room 11 is heated to a temperature (about 70 to about 80 ° C.) suitable for a lowry sauna by infrared rays and convection heat radiation radiated from the first heat radiation pipe 16 and the second heat radiation pipe 17 of the heater device 12. Then, the high-temperature steam released from the steam generator 13 becomes a hot air flow environment suitable for a lowry sauna.

  The Roury sauna system 10A includes a heater device 12 that radiates the heat of combustion gas into the chamber of the sauna chamber 11 and a steam generator 13 that releases high-temperature vapor into the chamber of the sauna chamber 11 using the heat of the combustion gas. Since it is formed, from the heat first radiant tube 16 (the first undulating portion 26 and the first exposed portion 27) and the heat second radiant tube 17 (the first undulated portion 28 and the first exposed portion 29) of the heater device 12. The heat (thermal energy) of the combustion gas can be heated to a temperature (about 70 to about 80 ° C.) suitable for a lowry sauna by infrared radiation and convection heat radiation, and a large amount of high temperature is generated from the steam generator 13. By generating steam, a large amount of high-temperature steam can be discharged and filled in the sauna room 11, and the sauna room 11 can be quickly made into a lowry sauna environment. Kill.

  Since the sauna stone 34 located at the top 35 of the casing 31 is heated to a higher temperature than the sauna stone 34 located at the intermediate part 36 and the bottom 37, the water poured from the top opening 32 is at the top. It is instantly vaporized by the sauna stone 34 located at 35, and a large amount of high-temperature steam can be released from the steam generator 13 into the room of the sauna room 11 in a short time, and the sauna room 11 is a hot air environment suitable for a lowry sauna Can be.

  When the high temperature steam is generated by pouring water from the top opening 32 in the Roury sauna system 10A, the temperature of the sauna stone 34 located at the top 35 first decreases, but the combustion gas flows from the top 35 of the casing 31 to the bottom 37. Since the sauna stone 34 positioned at the top portion 35 is quickly reheated and the sauna stone 34 positioned at the intermediate portion 36 and the bottom portion 37 is quickly reheated, the steam generator 13 The generation cycle of the high-temperature steam in can be shortened, and a large amount of high-temperature steam can be generated from the steam generator 13 a plurality of times in a short time.

  In the Rouryau sauna system 10A, the length of the first undulation portion 26 of the heat first radiant tube 16 is substantially half the length of the second undulation portion 28 of the heat second radiant tube 17, and the length of the first undulation portion 26 is long. By shortening the length, the loss of the thermal energy of the combustion gas in the first undulating portion 26 is prevented, and the thermal energy of the combustion gas is fully utilized in the steam generator 13, so that the sauna stone 34 of the steam generator 13 is heated to a high temperature. Water can be instantaneously vaporized in the sauna stone 34 by pouring water into the sauna stone 34. The Roulyu sauna system 10A increases the length of the second undulation portion 28 of the second heat radiation tube 17 to generate infrared radiation and convection heat radiation sufficient to heat the sauna chamber 11 from the radiation tube 17. The temperature of the sauna room 11 can be heated and maintained at the set temperature.

  The steam generator 13 includes a casing 31 having a predetermined volume long in the vertical direction, a lid 33 (hatch) capable of opening and closing the top opening 32 of the casing 31, and a plurality of saunas housed in the housing space 45 (inside) of the casing 31. It has a stone 34, a combustion gas inlet 38 made at the top 35 of the casing 31, and a combustion gas outlet 39 made at the bottom 37 of the casing 31. Although not shown in the figure, the steam generator 13 is provided with an open / close sensor that detects the opening / closing of the lid 33 and outputs an open / close signal.

  The combustion gas inlet 38 is connected to the first exposed portion 27 of the heat first radiation pipe 16, and the first exposed portion 27 is connected to the combustion gas inlet 38 (the top portion 35 of the casing 31). The combustion gas outlet 39 is connected to the second exposed portion 29 of the second heat radiation pipe 17, and the second exposed portion 29 is connected to the combustion gas outlet 39 (the bottom 37 of the casing 31). The combustion gas bypass pipe 47 is made of a metal such as iron or stainless steel and is formed into a cylindrical shape. The bypass pipe 47 is connected to the first exposed portion 27 of the thermal first radiant tube 16 and the second exposed portion 29 of the thermal second radiant tube 17, and connects the first exposed portion 27 and the second exposed portion 29. ing.

  A first motor damper 48 is installed in the first exposed portion 27 extending between the casing 31 (combustion gas inlet 38) and the combustion gas bypass pipe 47. A second motor damper 49 is installed in the second exposed portion 29 extending between the casing 31 (combustion gas outlet 39) and the combustion gas bypass pipe 47. A third motor damper 50 is installed in the combustion gas bypass pipe 47. In addition, it can replace with these motor dampers 48-50 and a manual damper can also be used.

  The first to third motor dampers 48 to 50 control the modular roll motor, the swirling blades swirled by the driving force of the motor, the air flow path opened and closed by swirling of the swirling blades, and the control for swirling the swirling blades. Part. The control units of the first to third motor dampers 48 to 50 are connected to the controller 51 via the interface 52. The open / close sensor installed in the steam generator 13 is connected to the controller 51 via the interface 52.

  The control unit of the first to third motor dampers 48 to 50 rotates the modulated roll motor according to the opening / closing signal output from the controller 51, thereby changing the turning angle (damper opening) of the swirling blades. Open or close the flow path. When an open signal is output from the controller 51 and the air flow paths of the motor dampers 48 to 50 are opened, the combustion gas flows into the steam generator 13 or the combustion gas bypass pipe 47. When a closing signal is output from the controller 51 and the air flow paths of the motor dampers 48 to 50 are closed, the inflow of combustion gas to the steam generator 13 or the combustion gas bypass pipe 47 is blocked.

  The flow of combustion gas, the radiation of heat, and the release of high-temperature steam in the Lauryau sauna system 10B will be described based on FIGS. 7 to 11 as follows. When the switch is turned on on the operation panel, the control device activates the heater device 12 in accordance with the input ON signal. When the heater device 12 is activated, combustion air is supplied from the air supply port to the burner 15 by the fan 19, and fuel is supplied to the burner 15. The burner 15 ignites an air-fuel mixture obtained by mixing combustion air and fuel, and combusts the air-fuel mixture to generate combustion gas.

  The combustion gas produced by the burner 15 flows from the burner 15 into the heat first radiant tube 16 and flows through the first undulation portion 26 of the heat first radiant tube 16 as indicated by an arrow L1 in FIG. The first undulation portion 26 flows into the first exposed portion 27. In the process in which the combustion gas flows through the heat first radiant tube 16, the combustion heat (thermal energy) is transmitted to the entire surface of the heat first radiant tube 16, and the combustion heat becomes infrared rays, and the surface of the first undulation portion 26. The heat is radiated from the entire area to the front of the housing 14 and is radiated from the entire surface of the first exposed portion 27, and the thermal energy (infrared rays) of the combustion gas is radiated into the sauna chamber 11 (see FIG. 2).

  In a state where the lid 33 is closed and the top opening 32 of the casing 31 is closed, a closing signal is output from the open / close sensor to the controller 51, and the controller 51 determines that the top opening 32 is closed, and outputs the opening signal. While outputting to the control part of the 1st and 2nd motor dampers 48 and 49, a close signal is output to the control part of the 3rd motor damper 50.

  As shown in FIG. 9, the control units of the first and second motor dampers 48 and 49 that have received the open signal from the controller 51 rotate the swirl vanes to open the air flow path, or already perform the air flow path. If is open, keep that state. The control unit of the third motor damper 50 that has received the closing signal from the controller 51 turns the swirl blade to close the air flow path, or maintains the state when the air flow path that has already been closed is closed. . In addition, when using a manual damper, the damper installed in the 1st and 2nd exposure parts 27 and 29 is opened manually, and the damper installed in the bypass pipe 47 is closed manually. The display on the control panel of the controller 47 indicates that the lid is closed.

  The combustion gas that has flowed into the first exposed portion 27 in the state of FIGS. 8 and 9 does not flow into the combustion gas bypass pipe 47 but passes through the first exposed portion 27 and is formed in the top portion 35 of the casing 31. After flowing from the inlet 38 into the casing 31 (inside the steam generator 13) and flowing from the top 35 of the casing 31 toward the bottom 37, the casing 31 passes through the combustion gas outlet 39 formed at the bottom 37 of the casing 31. It flows out of 31 (outside of the steam generator 13) and flows into the second exposed portion 29. In the steam generator 13, with the lid 33 closed and the top opening 32 of the casing 31 closed, the combustion gas flows from the top 35 to the bottom 37 of the casing 31, and from the sauna stone 34 located at the top 35 to the bottom. The sauna stones 34 are heated to a high temperature toward the sauna stones 34 located at 37.

  The combustion gas that has flowed out of the combustion gas outlet 39 (steam generating device 13) of the casing 31 flows into the second exposed portion 29 of the heat second radiation pipe 17, and the second exposure as shown by the arrow L1 in FIG. After flowing from the portion 29 to the second undulating portion 28, it flows from the second undulating portion 28 into the exhaust portion 30. In the process in which the combustion gas flows through the heat second radiant tube 17, the combustion heat (thermal energy) is transmitted to the entire surface of the heat second radiant tube 17, and the combustion heat becomes infrared rays, and the surface of the second undulation portion 28. The heat is dissipated from the entire area to the front of the housing 14 and is dissipated from the entire surface of the second exposed portion 29, and the thermal energy (infrared rays) of the combustion gas is dissipated into the sauna room 11 (see FIG. 2). The combustion gas whose thermal energy has been reduced (temperature decreased) due to heat radiation or heating of the sauna stone 34 flows into the exhaust part 30 and is then exhausted from the exhaust port 18 to the outside of the sauna room 11 (outside air) through the fan 19. The

  When the high temperature steam is generated in the steam generator 13, the lid opening button displayed on the touch panel of the control panel of the controller 51 is pushed. When the lid opening button is pressed, a lid opening request signal is transferred to the controller 51. The controller 51 outputs a closing signal to the control units of the first and second motor dampers 48 and 49, and an opening signal is transmitted to the third motor damper 50. Output to the control unit. As shown in FIG. 9, the control units of the first and second motor dampers 48 and 49 that have received the closing signal from the controller 51 rotate the swirl vanes to close the air flow path. The control unit of the third motor damper 50 that has received the open signal from the controller 51 turns the swirl blade to open the air flow path.

  When the air flow paths of the first and second motor dampers 48 and 49 are closed, the first exposed portion 27 extending between the combustion gas inlet 38 and the bypass pipe 47 is closed, and the combustion gas outlet 39 The second exposed portion 29 extending between the bypass pipe 47 and the bypass pipe 47 is closed, and the inflow of combustion gas from the top portion 35 of the casing 31 to the accommodating space 45 (inside) is blocked. When the combustion gas bypass pipe 47 is opened, the combustion gas flows from the first exposed part 27 through the bypass pipe 47 into the second exposed part 29. In addition, when using a manual damper, the damper installed in the 1st and 2nd exposure parts 27 and 29 is closed manually, and the damper installed in the bypass pipe 47 is opened manually.

  When the air flow paths of the first and second motor dampers 48 and 49 are closed and the air flow path of the third motor damper 50 is opened, the lid of the controller 51 is displayed. After confirming the lid openable message, the foot pedal 46 is stepped on to open the lid 33 and the top opening 32 of the casing 31 is opened. In addition, when the lid 33 is an automatic opening / closing type, the lid 33 is automatically opened. When the lid 33 is opened and the top opening 32 of the casing 31 is opened, an open signal is output from the open / close sensor to the controller 51. The controller 51 determines that the top opening 32 has been opened, and displays on the display that the lid is being opened and also indicates that the lid can be closed.

  After opening the top opening 32 of the casing 31, water is poured from the top opening 32 to the sauna stones 34 accommodated in the accommodation space 45 of the casing 31 using a handle. When water is injected, the burner 15 and the fan 19 of the heater device 12 are operated, combustion gas is generated, and the combustion gas flows from the heat first radiation pipe 16 through the bypass pipe 47 into the heat second radiation pipe 17. The heat is radiated from the radiation tubes 16 and 17 (including the bypass tube 47). When water is poured into the sauna stone 34, the sauna stone 34 located at the top 35 of the casing 31 is heated to a high temperature, so that water instantly vaporizes at the top 35 of the casing 31, and as shown by an arrow L3 in FIG. A large amount of high-temperature steam is released from the top opening 32 into the sauna room 11 at a stretch, and the high-temperature steam fills the room of the sauna room 11.

  After the release of the high-temperature steam from the top opening 32 of the casing 31 is completed, the depression of the pedal 46 is released, the lid 33 is closed, and the top opening 32 is closed. When the lid 33 is closed and the top opening 32 of the casing 31 is closed, a closing signal is output from the open / close sensor to the controller 51. The controller 51 determines that the top opening 32 is closed, and the opening signal is the first signal. In addition, the control signal is output to the control unit of the second motor dampers 48 and 49 and the close signal is output to the control unit of the third motor damper 50. When the lid 33 is an automatic opening / closing type, a lid closing button is displayed on the touch panel, and the closing button is pressed. When the close button is pressed, the lid 33 is automatically closed.

  The control units of the first and second motor dampers 48 and 49 that have received the open signal from the controller 51 rotate the swirl vanes to open the air flow path and the third motor damper 50 that has received the close signal from the controller 51. The controller turns the swirl vane to close the air flow path. In addition, when using a manual damper, the damper installed in the 1st and 2nd exposure parts 27 and 29 is opened manually, and the damper installed in the bypass pipe 47 is closed manually. The display on the control panel of the controller 47 indicates that the lid is closed.

  When the combustion gas bypass pipe 47 is closed, the inflow of combustion gas from the first exposed portion 27 to the bypass pipe 47 is blocked. When the air flow paths of the first and second motor dampers 48 and 49 are opened, the first exposed portion 27 extending between the combustion gas inlet 38 and the bypass pipe 47 is opened and the combustion gas outlet 39 is opened. The second exposed portion 29 extending between the bypass pipe 47 and the bypass pipe 47 is opened, and the combustion gas flows from the top portion 35 of the casing 31 into the accommodating space 45 through the first exposed portion 27, and from the bottom portion 37 of the casing 31 to the casing 31. And flows into the second exposed portion 29 (see FIG. 9).

  After the top opening 32 is closed, the sauna stones 34 are reheated by allowing combustion gas to flow from the top 35 to the bottom 37 of the casing 31. In the reheating of the sauna stones 34, the sauna stone 34 positioned at the top 35 of the casing 31 is heated before the sauna stone 34 positioned at the intermediate portion 36, and the sauna stone 34 positioned at the intermediate portion 36 of the casing 31 is heated. The sauna stone 34 located at the bottom 37 is heated before the sauna stone 34 located at the top 35, and the sauna stone 34 located at the top 35 is heated to a temperature higher than the sauna stone 34 located at the intermediate part 36 and the bottom 37. After reheating the sauna stones 34, the lid 33 is opened to open the top opening 32 of the casing 31, and water is poured into the sauna stones 34 accommodated in the accommodation space 45 of the casing 31 from the top opening 32. A large amount of high-temperature steam can be discharged again from the opening 32 into the sauna room 11.

  The interior of the sauna room 11 is heated to a temperature (about 70 to about 80 ° C.) suitable for a low-temperature sauna by heat radiation from the first heat radiation pipe 16 and the second heat radiation pipe 17 of the heater device 12, and the steam generation device 13. The hot steam released from the water creates a hot air environment suitable for lowry saunas.

  In addition to the effects that the system 10A of FIG. 1 has, the Lauryau sauna system 10B has the following effects. When the top opening 32 of the casing 31 is opened in the state where the combustion gas bypass pipe 47 is not installed, for example, the air (outside air) is transferred from the top opening 32 to the accommodation space 45 (inside) of the casing 31. As the air enters, the air enters the second heat radiation tube 17 and the first heat radiation tube 16 and the burner 15 cannot be held at a negative pressure, and the combustion gas smoothly flows from the burner 15 toward the exhaust port 18. Although it becomes impossible to cause the combustion gas to flow into the bypass pipe 47 when the top opening 32 of the casing 31 is opened by installing the bypass pipe 47, air (outside air) flows into the heat second radiation pipe 17. Does not enter, the heat first radiation tube 16 and the burner 15 can be held at a negative pressure, and the combustion gas is circularly directed from the burner 15 toward the exhaust port 18. It can be made to flow in.

  Further, when the top opening 32 of the casing 31 is opened without the bypass pipe 47 being installed, the generated high-temperature steam is discharged from the exhaust port 18 to the outside of the sauna room 11 through the heat second radiation pipe 17. However, by installing the bypass pipe 47, the combustion gas flows into the bypass pipe 47 when the top opening 32 of the casing 31 is opened, and the combustion gas flows from the top 35 of the casing 31 toward the bottom 37. The generated high-temperature steam can be reliably discharged from the top opening 32 of the casing 31 into the sauna room 11.

  Further, when air enters the housing space 45 of the casing 31, the air is mixed with the combustion gas, the thermal energy of the combustion gas is reduced, and high heat energy cannot be radiated from the heat second radiation pipe 17. Since the combustion gas flows into the second exposed portion 29 through the bypass pipe 47 during the opening of the opening 32, it is possible to prevent a decrease in the thermal energy of the combustion gas during the opening of the top opening 32, and the second heat radiation tube Sufficient heat energy can be radiated into the room of the sauna room 11 via the heat source 17, and the temperature of the sauna room can be heated and maintained at about 70 to about 80 ° C. suitable for a low-temperature sauna. Although the combustion gas may leak from the top opening 32 during the opening of the top opening 32 and an unexpected accident may occur due to the combustion gas, there is a concern that the combustion gas may leak from the top opening 32 during the opening of the top opening 32. In addition, unexpected accidents caused by combustion gas can be prevented.

  When the lid 33 is closed and the top opening 32 of the casing 31 is closed, the bypass sauna 47 is closed, and the first exposed portion 27 extending between the combustion gas inlet 38 and the bypass pipe 47 is opened. In addition, the second exposed portion 29 extending between the combustion gas outlet 39 and the bypass pipe 47 is opened, and the combustion gas immediately flows from the top portion 35 of the casing 31 toward the bottom portion 37. After 32 is closed, the combustion gas can flow into the accommodation space 45 of the casing 31 and the sauna stone 34 can be reheated quickly.
