Description

[Technical Field]

[0001] The present invention relates to a sauna room that is easy to assemble and has high heat retention. [Background technology]

[0002] Saunas are hot air baths that are said to have a variety of benefits, such as improving oxygen intake to relieve fatigue, temperature stimulation to relieve stress, dilating blood vessels to lower blood pressure, promoting restful sleep in low-temperature saunas, improving blood circulation to relieve stiff shoulders, promoting weight loss, regulating the autonomic nervous system to strengthen blood vessels, and improving cardiac function.

[0003] There is a need to enjoy these benefits easily, for example, in an ordinary home, and small saunas that can be installed in small spaces have been proposed (see, for example, Patent Document 1).

[0004] However, the "prefabricated far-infrared sauna bathroom" described in Patent Document 1 is structured so that the four sides are formed by cover plates and doors, and heating elements made of far-infrared radiative material are installed on three of the cover plates, excluding the entrance door area.However, there is no technical idea behind giving the three cover plates insulating properties to prevent heat from moving from inside the sauna bathroom to the outside, thereby keeping the sauna bathroom warm.

[0005] Small saunas that are said to have excellent heat retention capabilities have also been proposed (for example, Patent Document 2).

[0006] However, the "hot air convection type dry sauna bath with heat retention function" described in Patent Document 2 is said to have excellent heat retention and temperature-raising properties, as the interior walls of the sauna room are constructed by attaching many interior boards at intervals on top of spaced joists, which allows the dry hot air sent from the sauna stove to be stored (heat storage chamber).However, because there are spaces (gaps) between the interior boards that allow the dry hot air to enter and exit, the effectiveness of storing the dry hot air is low.Furthermore, there is no mention of prefabricated saunas.

[0007] Small saunas that are easy to install and use heat insulating materials have also been proposed (for example, Patent Document 3).

[0008] However, the "simple mist sauna" described in Patent Document 3 is a mist sauna that can be easily set up, particularly in a home bathhouse, and has an insulating barrier that is detachably attached via temporary fasteners along the periphery of the ceiling body, with insulating material bonded integrally between the front and back waterproof cloths, and engaging devices arranged on the left and right ends of the front, allowing it to be opened and closed freely; however, the insulating material is only a foam resin sheet, and the insulating effect is low.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The sauna room of the present invention is a sauna room of approximately rectangular parallelepiped shape, and the walls forming the sides of the sauna room have multiple panels, an entrance with an opening and closing door, a ventilation opening in at least one of the panels, and an exhaust opening in at least one of the panels, and the air layers inside the panels are connected to each other via air layer passages. Below, the prefabricated sauna room (A) of the present invention will be explained based on the drawings. [Example]

[0017] Figure 1 is a photograph showing a sauna room according to the first embodiment of the present invention. Side panels 7, 8, 9, 10, 11, (3), (4), (5), and (6), including a door panel 10, are installed on top of a floor panel 2, and finally a ceiling panel 1 is placed on top. The first embodiment is a sauna room for two people.

[0018] Figure 2 is a plan view of the side panels that make up the side of the sauna room according to the first embodiment of the present invention. Nine types of side panels are connected using connecting jigs 18 and 19 that are pre-installed on the side panels. The side panels of the present invention are basically composed of an outer wall 16, an inner wall 17, support columns 23, a panel made up of an insulating layer 20 (12 and 13), and a door panel 10.

[0019] The side panels have a basic rectangular structure with at least two supporting posts and frames at the top and bottom of the posts as needed. The supporting posts and frames can be made of wood, metal, plastic, or other materials commonly used in construction, but wood is superior in terms of strength, insulation, and workability.

[0020] Windows can also be installed on the side panels, so if you install it in a room in a high-rise building, you can enjoy the sauna while looking out at the scenery below.

[0021] Figure 3 is a plan view of the assembled side panels shown in Figure 2. The side panels are connected to each other using connecting jigs 18 and 19 that are pre-installed on the side panels. In the case of a two-person sauna room, as shown in Figure 3, it is made up of nine types of side panels, including a door panel 10.

[0022] The assembly method is simple: first, place the floor panel horizontally, then place the side panel on top in the designated position and secure it to the floor panel using fixing hardware commonly used in construction. The side panels are connected to each other using connecting jigs that are pre-installed on the side panels. Once all the side panels have been connected, simply place the ceiling panel on top to complete the installation.

[0023] Figure 4 is a photograph substituting for Figure 3. Between an outer wall 16 and an inner wall 17, there are heat insulating material 12, a heat shield sheet 13, and an air layer 14, and the heat insulating layer 20 is divided by a support 23, but the air layers 14 communicate with each other through a groove-shaped air layer passage 15 provided in the support 23.

[0024] Materials that can be used as insulation include rock wool, glass wool, phenolic foam, rigid urethane foam, bead-formed expanded polystyrene foam, and extruded expanded polystyrene foam, which are commonly used in construction. Among these, Styrofoam (Styrofoam is a registered trademark of The Dow Chemical Company), a type of extruded expanded polystyrene foam, is superior in terms of insulation performance, light weight, workability, and cost.

[0025] Heat-shielding sheets can be made from materials that can reflect radiant heat, such as aluminum foil or aluminum vapor deposition sheets, which are commonly used in construction, but among them, Thermobarrier W (Thermobarrier is a registered trademark of Life Tech Co., Ltd.), which has a structure of double air caps and aluminum foil on both sides, is superior.

[0026] The heat insulating layer may be a combination of a heat insulating material and a heat shielding sheet, or may be either of them alone, but in order to enhance the heat retention effect, a combination of a heat insulating material and a heat shielding sheet is preferred.

[0027] Figure 5 is a photograph substituting for a drawing, enlarging a portion of Figure 4. Side panel d6 and side panel e7 are connected by connecting jigs 18 and 19. The insulation material 12 and the heat-shielding sheet 13 (insulation layer 20) are separated by support 23, but the air layer 14 communicates with each other through air layer passages 15 provided in the support 23. The outer wall 16 and inner wall 17 are made of approximately 10 cm wide cedar boards that have been processed into a slatted shape and nailed to the support 23.

[0028] Figure 6 is a photograph of the convex side of the connection jig. The convex part is inserted into the concave part to secure the panels together.

[0029] Figure 7 is a photograph of the air layer passage provided in the support. In this example, a groove approximately 10 mm deep and 40 mm wide is machined into the top of a wooden support, which is a square pillar, to serve as the air layer passage.

[0030] Figure 8 shows a cross-sectional view of part of a sauna room taken along the line AA. In this example, a ventilation vent and an exhaust vent are installed in the same panel, but since the air layers of each panel are connected to each other via air layer passages, the ventilation vent or exhaust vent can be installed anywhere other than the panel with the door.

[0031] When ventilation openings 21 and exhaust openings 22 that are in direct contact with the air layer 14 are installed on the side panels, the indoor air under the feet is sucked in through the ventilation openings 21 by the rising air current of the heated air layer 14 over the inner wall, resulting in agitation of the air in the sauna room. At the same time, the air layer 14 is connected by the air layer passage 15, which promotes uniform temperature of each panel and further enhances the heat retention effect. [Example]

[0032] Figure 9 shows a sauna room assembled from Example 1 by removing side panel a3 and side panel f8, making it a one-person sauna room.

[0033] In other words, the size of this sauna room can be adjusted by increasing or decreasing the side panels as appropriate. [Industrial Applicability]

[0034] The sauna room of the present invention is ideal for a so-called Finnish-style sauna, in which a loyly device is installed in the sauna room and water is poured onto the sauna stones with a ladle or the like to cause steam and vapor to rise. [Explanation of symbols]
