Brief Description of the Drawings

[0008] [Figure 1] It is a schematic cross-sectional view of the sauna bath according to the present invention.< [Figure 2] It is a view for explaining the container sauna and the mobile sauna according to the present invention.<

Modes for Carrying Out the Invention

[0009] Embodiments of the sauna bath 80 according to the present invention, the container sauna 90 provided with this sauna bath 80, and the mobile sauna 100 will be described based on the drawings. Here, a transport container is used as the structure, and the sauna bath 80 provided inside this transport container is used as an example to explain the present invention. However, the installation location of the sauna bath 80 according to the present invention, that is, the structure, is not limited to the transport container, and it can also be applied to permanent buildings such as accommodation facilities, hot spring facilities, leisure facilities, sports facilities, commercial facilities, villas, temporary buildings such as prefabricated houses, and camping cars.<

[0010] Here, FIG. 1 is a schematic cross-sectional view of the sauna bath 80 according to the present invention. First, the sauna bath 80 according to the present invention has a sauna room 60 installed inside the structure and heating equipment 20 installed inside this sauna room 60.<

[0011] Furthermore, there are no particular limitations on the heating equipment 20; any equipment suitable for use as sauna heating equipment 20, such as electric heaters or gas heaters, may be used. Among these, the use of a wood-burning stove that burns firewood or charcoal is most preferable. In a configuration using this wood-burning stove as the heating equipment 20, the flames of the firewood or charcoal emit a large amount of far-infrared rays that warm the human body, resulting in a high thermal effect. In addition, the brick wall layer 36 described later can be heated efficiently. Moreover, the flames of the firewood or charcoal visible through the furnace window can provide visual relaxation to users and help relieve stress.

[0012] Furthermore, the sauna bath 80 according to the present invention can be applied to any well-known sauna, including Finnish-style saunas in which sauna stones 22 are heated by a heating device 20 and the sauna room 60 is heated through the sauna stones 22, as well as Russian-style saunas (banya), Korean-style saunas (hanjeungmak), Turkish-style saunas (hammam), dry saunas (Japanese-style saunas), mist saunas, and steam saunas. In addition, when using sauna stones 22 in the present invention, it is particularly preferable to use white bricks that are mainly composed of silicon and have an iron oxide content of less than 3.0 wt%. Here, far-infrared rays with a wavelength of 8 μm to 14 μm (hereinafter referred to as the growth band) are also called growth rays and are said to easily resonate with water molecules in the human body, warming the user's body to its core, promoting blood circulation, improving metabolism, and providing thermal benefits. Furthermore, silica (SiO2: silicon dioxide), an oxide of silicon, is known to absorb and emit far-infrared rays with a wavelength of 9 μm to 12 μm, which belongs to this growth band, the most. Therefore, the sauna stone 22 of the present invention, which has silicon as its main component, emits a large amount of far-infrared rays in the growth zone and can exert a high thermal effect on people. Iron oxide is said to absorb and emit far-infrared rays with wavelengths of 3 μm to 6 μm the most, and as the content of iron oxide increases, the amount of silica, i.e., the amount of far-infrared rays emitted in the growth zone, decreases relatively, which is undesirable. Therefore, the sauna stone 22 of the present invention uses iron oxide components with a content of less than 3.0 wt%.

[0013] Furthermore, in this invention, it is most preferable to use white bricks made from Larnage clay as the sauna stones 22. Larnage clay is a high-quality white clay (pottery clay) that is sourced from the Larnage region of France and is also used as a mud pack. It is mainly composed of silicon and has a low iron oxide content. In addition, bricks made from this Larnage clay have particularly excellent heat retention properties and are highly valued as a material for special wood-fired kilns and furnaces. In the sauna bath 80 according to the present invention, by using white bricks made from this highly heat-retaining Larnage clay as the sauna stones 22, far-infrared rays in the growth zone are emitted very effectively, providing users with an excellent thermal effect.

[0014] Next, the configuration of the sauna bath 80 according to the present invention will be explained. First, the sauna bath 80 according to the present invention is constructed inside a structure having side walls 52a, a bottom surface 52b, and a top surface 52c. If the structure is a permanent building or a prefabricated building, the side walls 52a, bottom surface 52b, and top surface 52c are the side walls, underside of the floor, and roof (or underside of the floor of the upper floor) of that structure. If it is a shipping container, then the sides, bottom, and top surfaces are those of the container. In the case of a shipping container, the side walls 52a, bottom surface 52b, and top surface 52c are basically all made of metal.

[0015] Inside the side walls 52a, bottom surface 52b, and top surface 52c, the side wall insulation layer 32a, floor insulation layer 32b, and top surface insulation layer 32c, which constitute the sauna bath 80 of the present invention, are provided. These side wall insulation layers 32a, floor insulation layer 32b, and top surface insulation layer 32c have the function of preventing the heat of the sauna bath 80 from being released to the outside (side walls 52a, bottom surface 52b, top surface 52c), and well-known building insulation materials such as glass wool, rock wool, polyurethane foam, polyethylene foam, and Styrofoam (registered trademark) can be used. In particular, it is preferable to use a plate-shaped building insulation board made of these well-known materials for the floor insulation layer 32b. Furthermore, there are no particular limitations on the thickness of these side wall insulation layers 32a, floor insulation layer 32b, and top surface insulation layer 32c, but it is preferable that they be about 30 mm to 100 mm thick.

[0016] Furthermore, flame-retardant, plate-shaped heat storage layers 34a and 34c are provided inside the side wall insulation layer 32a and the top surface insulation layer 32c. In addition to their fire-prevention function, these heat storage layers 34a and 34c store heat from within the sauna room 60, suppressing heat outflow to the insulation layers 32a and 32c, and also transfer heat emitted from the heating equipment 20 to the walls and ceiling of the sauna room 60. Therefore, it is preferable to use materials for the heat storage layers 34a and 34c that have a high specific heat and relatively high thermal conductivity for a ceramic material, specifically materials with a specific heat of 0.8 kJ / Kg·K to 1.5 kJ / Kg·K and a thermal conductivity of 0.4 W / m·K to 1.8 W / m·K. ru. Examples of such heat storage layers 34a and 34c include well-known plate-like members mainly composed of inorganic materials such as cement board and calcium silicate board, and among these, it is particularly preferable to use cement board that does not use organic fibers such as wood wool. There are no particular limitations on the thickness of the heat storage layers 34a and 34c, but a thickness of about 4 mm to 20 mm is preferred, and when using well-known cement board, it is preferable to use one that is 6 mm or 11 mm thick. Furthermore, in this invention, the heat storage layer 34c installed on the upper surface constitutes the ceiling of the sauna room 60. ru.

[0017] Furthermore, it is preferable to form a curved section at the boundary between the wall and ceiling of the sauna room 60, and to form this curved section, it is preferable to provide an arc-shaped heat storage layer 34ac that connects the heat storage layer 34a on the wall side and the heat storage layer 34c on the ceiling side. In addition, a well-known building material such as a bendable cement board can be used as this curved heat storage layer 34c. Furthermore, it is preferable to provide an insulating layer 32ac made of the same material as the insulating layers 32a, 32b, and 32c on the back side of the heat storage layer 34ac.

[0018] Furthermore, a side wall brick layer 36, which constitutes the wall surface of the sauna room 60, is provided inside the heat storage layer 34a of the side wall. This side wall brick layer 36 is made of bricks that are mainly composed of silicon and have an iron oxide content of less than 3.0 wt%. In addition, in the configuration of the sauna room 60 which has a curved section, it is preferable to also provide a side wall brick layer 36 in the heat storage layer 34ac of this curved section. Examples of bricks that are mainly composed of silicon and have an iron oxide content of less than 3.0 wt% include the aforementioned white bricks (including white bricks made from Larnage white clay), as well as yellow ochre bricks, firebricks, silica bricks, etc. Furthermore, it is preferable to use bricks with an apparent porosity of 10% to 28% for this side wall brick layer 36, from the viewpoint of performing löyly on the wall surface, as will be described later. Furthermore, there are no particular limitations on the thickness of the side wall brick layer 36, but it is preferably about 10 mm to 60 mm, and it is especially preferable to use relatively thin plate-like material of 10 mm to 20 mm. Brick tiles may also be used. In this invention, it is most preferable to make the entire wall surface of the sauna room 60 the side wall brick layer 36, but it is sufficient if at least a part of the wall surface has this configuration.

[0019] The side wall brick layer 36 absorbs far-infrared rays, particularly those in the growth band, emitted from the heating equipment 20, causing its temperature to rise. In this configuration, where white bricks are used for the sauna stones 22, the sauna stones 22 themselves emit a large amount of far-infrared rays in the growth band, resulting in high heat (far-infrared) transfer between them and the side wall brick layer 36, allowing for efficient heating of the side wall brick layer 36. Furthermore, the heat from a portion of the heated side wall brick layer 36 is stored and conducted in the heat storage layers 34a, 34c, and 34ac, and then transmitted and supplied to the entire side wall brick layer 36 within the sauna room 60. The side wall brick layer 36 then emits an amount of far-infrared rays corresponding to its temperature. As mentioned above, bricks, which are mainly composed of silicon, emit more far-infrared rays in the growth band with wavelengths of 9 μm to 12 μm, which warm the human body deeply, than other bands. Therefore, in the sauna bath 80 according to the present invention, in addition to far-infrared rays from the heating equipment 20 and sauna stones 22, far-infrared rays in the growth zone are emitted from the side wall brick layer 36 of the sauna room 60 wall surface. As a result, the user's body is warmed not only from the heating equipment 20 side but also from the side wall brick layer 36 on the back and sides, allowing the entire body to experience the warming effect. Furthermore, in configurations where the side wall brick layer 36 is also provided in the curved section, far-infrared rays in the growth zone are radiated from this side wall brick layer 36 in the curved section diagonally downwards towards the sauna room 60. Therefore, for example, far-infrared rays in the growth zone are radiated to areas where far-infrared rays from the wall surface do not easily reach, such as the upper part of the user's shoulders, allowing these areas to experience the same warming effect as other areas. Moreover, the amount of far-infrared rays from these side wall brick layers 36 is less than that from the heating equipment 20 side, and they contain more far-infrared rays in the growth zone, resulting in a gentler warming effect that penetrates deep into the user's body.

[0020] As mentioned earlier, iron oxide (FeO, Fe2O3) is said to absorb and emit far-infrared rays with wavelengths of 3 μm to 6 μm most readily. Therefore, typical red bricks containing a large amount of iron oxide (usually 4% to 8%) absorb and emit far-infrared rays across a wide wavelength range of 3 μm to 12 μm, including the growth band. Far-infrared rays outside the growth band heat the surface layer (skin) of the human body, causing the user to feel heat, and if this is excessive, pain receptors react, resulting in painful heat.

[0021] In this regard, the sauna bath 80 according to the present invention uses bricks with silicon as the main component and an iron oxide content of less than 3.0 wt% for the side wall brick layer 36, so that the amount of far-infrared radiation in the growth zone is large, and in addition to the heating equipment 20 and sauna stones 22, the entire wall surface of the sauna room 60 can provide gentle heat that warms the user's body thoroughly.

[0022] Thus, the sauna bath 80 according to the present invention provides heating through far-infrared rays in the growth zone of the entire sauna room 60, resulting in a higher thermal effect on the human body compared to conventional saunas with only heating equipment 20. Even if the temperature of heating equipment 20 is lowered, sufficient thermal effect can still be obtained. As a result, users can enjoy the sauna for extended periods.

[0023] Next, the floor side of the sauna bath 80 according to the present invention will be described. As mentioned above, in the sauna bath 80 according to the present invention, a floor insulation layer 32b is installed inside the bottom surface 52b of the structure. Inside this floor insulation layer 32b, a heat storage and heat insulation layer 40 having heat storage and heat insulation properties is provided. It is preferable to use silica blocks as firebricks for this heat storage and heat insulation layer 40, with silicon as the main component, an iron oxide content of less than 3.0 wt%, and a specific heat of 0.8 kJ / Kg·K to 1.5 kJ / Kg·K.

[0024] Furthermore, a natural stone layer 42, which forms the floor surface of the sauna room 60, is provided inside this thermal insulation layer 40. It is preferable to use processed natural stone for this natural stone layer 42, which has a low water absorption rate and high thermal conductivity, particularly one with a water absorption rate of 0.2% to 0.5%, a thermal conductivity of 2 W / m·K to 4 W / m·K, and a density of 2.0 g / cm³. 3 ~3.0g / cm 3 It is particularly preferable to use granite such as Mikage stone. Furthermore, the thickness of the natural stone layer 42 is preferably about 10 mm to 50 mm from the standpoint of weight.

[0025] Furthermore, unlike the side wall brick layer 36, this granite emits far-infrared rays in a broad band of 4 μm to 100 μm. As mentioned above, far-infrared rays outside the growth band of 8 μm to 14 μm have the property of warming the surface layer (skin) of a person. In a typical sauna, the upper body may get hot, but the lower body may not get very warm. In this respect, in the sauna bath 80 according to the present invention, the natural stone layer 42 provided on the floor surface emits broad-band far-infrared rays, so the user's feet are warmed from the surface layer of the skin, stimulating the heat receptors and preventing them from feeling cold. In addition, because granite has a high thermal conductivity as a natural stone, the natural stone layer 42 of the present invention can quickly transfer heat from the heating equipment 20 to the entire floor surface and effectively warm the soles of the user's feet. Moreover, the natural stone layer 42 warms the air at the bottom of the sauna room 60, creating convection and making it possible to warm the entire air in the sauna room 60. Furthermore, users can also perform a bedrock bath within the sauna room 60 by lying down on the natural stone layer 42. Since there is an insulating layer 40 beneath the natural stone layer 42, the heat from the natural stone layer 42 is less likely to escape, allowing the heat from the natural stone layer 42 to be effectively used to warm the users.

[0026] Furthermore, the natural stone layer 42 has a low water absorption rate of 0.2% to 0.5%, providing waterproofing and preventing sweat and water from seeping into the floor. This prevents moisture from penetrating to the storage insulation layer 40, floor insulation layer 32b, and bottom surface 52b beneath the natural stone layer 42, thereby reducing the amount of cleaning and maintenance work required inside the sauna room 60.

[0027] Furthermore, the sauna bath 80 according to the present invention may also be equipped with a water injector 70 that sprays water toward the side wall brick layer 36. There are no particular limitations on the water injector 70, and any mechanism may be used. Specifically, for example, a water injection pipe with multiple injection holes arranged on the side wall brick layer 36 side may be installed, and an on-off valve and a water supply pipe may be connected to this water injection pipe so that the user can spray water by opening and closing the on-off valve. Alternatively, a compressor may be connected to the water tank, and the user may operate the compressor and spray water by turning on a start switch provided in the sauna room 60. Furthermore, a manual pressure pump may be installed in the sauna room 60 so that the user can spray water from the water tank using the pressure of pressurized air. When water is sprayed onto the side wall brick layer 36 heated by the heating equipment 20 using the water injector 70, this water instantly evaporates due to the heat of the side wall brick layer 36 and generates steam. In this case, by spraying water over a wide area of ​​the side wall brick layer 36, steam is emitted in a planar manner from the entire surface of the side wall brick layer 36, allowing for a highly entertaining löyly experience where the side wall brick layer 36 is treated as a sauna stone.

[0028] Furthermore, as mentioned above, the sauna bath 80 according to the present invention may be installed in a fixed structure such as a building or prefabricated structure, but it may also be installed inside a transport container to form a unitized container sauna 90. In this case, as shown in Figure 2, the container sauna 90 has a water supply system 12 that functions by connecting to an external water supply pipe, a power supply system 14 that functions by connecting to an external power source (commercial power supply or power generation equipment), and a drainage system 13 that functions by connecting to an external drainage pipe such as a sewer. In addition, a propane gas cylinder may be installed inside the container sauna 90 or connected from the outside to make gas usable inside the container sauna 90. Furthermore, when the container sauna 90 is used as a mobile sauna 100 as described later, in accordance with vehicle regulations, it is preferable to use attachment connectors 12a, 13a, and 14a that can be attached and detached without the use of tools for connecting the water supply system 12, power supply system 14, and drainage system 13 to the outside. Furthermore, the sauna bath 80 according to the present invention is heavy because it uses bricks or the like. Therefore, it is preferable to use a shipping container with a large maximum load capacity, corresponding to the total weight of the sauna bath 80 and its ancillary equipment. Furthermore, if there is sufficient weight and space, a toilet, shower, cold bath, kitchen, living room, bedroom, etc. may be provided inside the container as needed, in addition to the sauna room 60.

[0029] Alternatively, this container sauna 90 may be mounted on a container transport chassis 10 having a coupler 16 for connecting to a towing vehicle and wheels 18, making it a mobile sauna 100 that can be moved. This mobile sauna 100 can then be moved by connecting it to a towing vehicle as needed, and installed in tourist spots, campgrounds, private land, accommodation facilities, leisure facilities, commercial facility grounds and parking lots, vacant lots in urban areas, construction sites, temporary housing sites and evacuation sites, etc., and connected to the above-mentioned water supply equipment 12, drainage equipment 13 and power supply equipment 14, making it possible to use it as a sauna in any of these locations.

[0030] As described above, the sauna bath 80 according to the present invention is provided with a side wall brick layer 36 on the wall surface, which is mainly composed of silicon that emits a large amount of far-infrared rays in the growth zone that have a high thermal effect on the human body, and has an iron oxide content of less than 3.0 wt%. In addition, heat storage layers 34a, 34c, and 34ac are installed on the back surface of this side wall brick layer 36, and these heat storage layers 34a, 34c, and 34ac transmit and supply heat from the heating equipment 20 to the entire side wall brick layer 36 in the sauna room 60. As a result, the sauna bath 80 according to the present invention can provide heating from far-infrared rays in the growth zone from the entire sauna room 60, resulting in a high thermal effect on the human body, and sufficient thermal effect can be obtained even if the temperature of the heating equipment 20 is lowered. As a result, users can enjoy the sauna comfortably for a long time.

[0031] Furthermore, by providing a natural stone layer 42 on the floor of the sauna bath 80 according to the present invention, a wide range of far-infrared rays are emitted. As a result, the user's feet are warmed from the surface of the skin, stimulating the heat receptors and preventing them from feeling cold. In addition, when granite is used for the natural stone layer 42, it has a high thermal conductivity for a natural stone, allowing users to perform a bedrock bath within the sauna room 60 by lying on the natural stone layer 42. Moreover, by installing a heat-storage layer 40 on the back of the natural stone layer 42, the heat from the natural stone layer 42 can be effectively used to warm the user.

[0032] Furthermore, in a configuration equipped with a water injector 70, water can be sprayed onto the heated side wall brick layer 36 by the water injector 70, allowing for a highly entertaining löyly experience where steam erupts in a planar manner from the entire wall.

[0033] Furthermore, the container sauna 90 incorporating the sauna bath 80 according to the present invention, and the mobile sauna 100 with the container sauna 90 mounted on a chassis 10, can be moved by connecting them to a towing vehicle, allowing them to be installed in various locations and used as saunas in any location. In addition, saunas can be installed even in areas where the construction of permanent buildings is restricted.

[0034] It should be noted that the configurations of the sauna bath 80, container sauna 90, and mobile sauna 100 shown in this example are merely examples, and the shape, dimensions, mechanisms, design, materials used, etc. of each part can be modified without departing from the spirit of the present invention.
