However, the tent sauna set disclosed in Patent Document 1 has a structure in which smoke is generated from a stove that burns liquid fuel such as ethanol, and the smoke is exhausted from a chimney attached to the stove. This limits not only its use in the home, but also its use in the balconies and gardens of ordinary households.
Furthermore, although the tent sauna disclosed in Non-Patent Document 1 uses a 100-volt household power supply and does not have the problem of smoke exhaust, even if it is a one-person tent, the temperature can only reach about 80 to 95 degrees Celsius. There is no expected rise in temperature, making it inadequate as a sauna for enjoying the high temperature range. On the other hand, it is possible to use an electric heater with a 200-volt power supply, but it is common to use an electric heater with a 200-volt power supply, but it is common to Since it is not possible to freely decide where to install a sauna within a home, its use in general homes is similarly restricted.

FIG. 2 is an image diagram for explaining changes in room temperature inside the sauna tent 1 according to an embodiment of the present invention. It is a figure which shows the photograph of the thermometer attached to the inner side of the inner tent 20 of the sauna tent 1 based on one Embodiment of this invention. FIG. 2 is an external view of a sauna tent 1 according to another embodiment of the present invention.

Hereinafter, a tent sauna set according to an embodiment of the present invention will be described with reference to the drawings. A tent sauna set according to an embodiment of the present invention includes a sauna tent 1 that can be used indoors in a general residence or outdoors on a rooftop or in a garden, and an electric heater 2 installed inside the tent.

FIG. 1 is an external view of a sauna tent 1 according to an embodiment of the present invention. The sauna tent 1 includes an inner tent 20 that forms a closed space that is heated by an electric heater 2 after being expanded, and an outer tent 10 that is expanded outside the inner tent 20, and has an air gap inside the outer tent 10. It has a structure in which the inner tent 20 is attached while forming the inner tent 20.

In the present embodiment, the outer tent 10 has a top surface 11, a bottom surface 16, and four side surfaces 12 to 15 (in FIG. 1, side surfaces 14 and 15 are not shown because they are the back side of side surfaces 12 and 13). In this case, each tent is formed by connecting quadrilateral tent cloths to form a substantially rectangular parallelepiped or cubic shape.
The side surface of the outer tent 10 may be made of a single sheet of tent cloth, such as a cylindrical surface, or may be formed by connecting two or more sheets of tent cloth with a plurality of curved or flat surfaces. You can. The shapes of the top surface 11 and the bottom surface 16 in the case of side surfaces having such shapes are determined to be such that they can be connected to form a closed space depending on each case.

FIG. 2 is an external view of the inner tent 20 of the sauna tent 1 according to an embodiment of the present invention. In this embodiment, the inner tent 20, like the outer tent 10, has a top surface 21, a bottom surface 26, and four side surfaces 22 to 25 (in FIG. ) are formed by connecting quadrilateral tent cloths to form a substantially rectangular parallelepiped or substantially cubic shape, assuming that the tent cloths in ) are flat. The side surface of the inner tent 20 may also be constructed of a single sheet of tent cloth, such as a cylindrical surface, or may be constructed by connecting two or more sheets of tent cloth with a plurality of curved or flat surfaces. You can. Moreover, the shapes of the top surface 21 and the bottom surface 26 in the case of side surfaces having such a shape are determined to be such that they can be connected to form a closed space depending on each case. However, as will be described later, the inner tent 20 is attached to the inside of the outer tent 10, and in order to make the air layer formed in the gap between the outer tent 10 and the inner tent 20 function as a heat insulating layer, It is desirable that the shape corresponds to the shape of the outer tent 10. In this embodiment, as described above, the outer tent 10 and the inner tent 20 have a substantially rectangular parallelepiped or substantially cubic shape.

Here, four frames are arranged from the center toward the four corners on each of the top surface 11 and four side surfaces 12 to 15 of the outer tent 10, and each of the four frames It is connected to the tent cloth so that it can be folded and opened and closed like an umbrella using a connector attached to the center of the tent cloth, and is integrally formed with the tent cloth. For example, a connector 111 is integrally formed in the center of the tent cloth on the top surface 11, and four frames 112 to 115 are foldably connected to the connector 111 inside the tent (in FIG. 1, the frame 112 is (not shown) are arranged toward the four corners of the tent cloth on the top surface 11. Similarly, a connector 121 is integrally formed in the center of the tent cloth on the side surface 12, and four frames 122 to 125 which are foldably connected to the inner side of the tent are connected to the connector 121 so that the tent cloth on the side surface 12 can be folded. They are arranged towards the four corners. The same applies to the other side surfaces 13 to 15.

The material of the frame may be, for example, a non-metal frame such as FRP or glass fiber, or a metal frame such as duralumin or aluminum. Then, the center portion of each tent cloth on the top surface 11 and four side surfaces 12 to 15 of the outer tent 10 is stretched to the outside of the tent, and the top surface 11 and four side surfaces 12 to 15 are stretched. By stretching all the tent cloths, the outer tent 10 can be fixed in the stretched state.

In addition, the connectors 111, 121, etc. of the tent cloth on the top surface 11 and the four side surfaces 12 to 15, the frame 112, etc. are attached to the tent cloth inside the tent cloth so that they are not directly visible from the outside of the tent. This will ensure a beautiful appearance. In addition, as will be described later, the outer tent cloth of the outer tent 10 is made of a durable, waterproof and moisture-proof sheet of Oxford cloth, etc., so the connectors 111 and the like and the frame 112 are integrated inside the tent cloth. By forming such a structure, the connector 111, etc., the frame 112, etc. are less susceptible to the influence of the external environment such as temperature, humidity, sunlight, snowfall, etc.

Here, in the expanded state of the outer tent 10, each of the tent cloths on the top surface 11 and four side surfaces 12 to 15 of the outer tent 10 is attached to the frame 112 to 115 by pulling the center portion of each tent cloth to the outside of the tent. , 122 to 125, etc. are expanded in the same manner as the umbrella ribs, and each tent cloth is expanded, so that the tent cloth forms a convex surface in the shape of a substantially quadrangular pyramid.

For example, in the present embodiment, the frame size of the top surface 11, side surfaces 12 to 15, and bottom surface 16 of the outer tent 10 ("the size of the frame when the edge portion of each tent cloth is used as a frame": the same applies hereinafter) is , the frame size of the top surface 11 and bottom surface 16 is approximately 100 cm (width: W) x approximately 100 cm (depth: D), and the frame size of sides 12 to 15 is approximately 100 cm (width: W) x approximately It is 135 centimeters (height: H).
Furthermore, when the outer tent 10 is in an expanded state, the top surface 11 and the side surfaces 12 to 15 each form a substantially square pyramid-shaped convex surface, but in this case, the height of the square pyramid of the top surface 11 is approximately 20 centimeters. , the height of the square pyramid with sides 12 to 15 is approximately 10 cm.

On the other hand, since the inner tent 20 is attached to the inside of the tent using connectors such as the top surface 11 and side surfaces 12 to 15 of the outer tent 10, the top surface 21 and side surfaces 22 to 25 of the inner tent 20 after being attached are attached to the inside of the tent. , and the frame size of the bottom surface 26, the frame size of the top surface 21 and the bottom surface 26 is approximately 100 cm (width: W) x approximately 100 cm (depth: D), and the frame size of the sides 22 to 25 is 100 cm. The size is approximately 135 cm (width: W) x approximately 135 cm (height: H), which is approximately the same as the frame size of the outer tent 10.

In addition, the shape of the inner tent 20 when attached to the expanded outer tent 10 is such that the top surface 21 and the side surfaces 22 to 25 each form a substantially quadrangular pyramidal convex surface. The height of the square pyramid on the surface 21 is about 15 centimeters, and the height of the square pyramid on the sides 22 to 25 is about 10 centimeters. That is, in the present embodiment, in the outer tent 10, the height (approximately 20 centimeters) of the substantially square pyramidal portion of the tent cloth on the top surface 11 is the height of the substantially square pyramidal portions of the tent cloths on the four sides 12 to 15. (approximately 10 centimeters). In addition, in the inner tent 20, the height of the approximately square pyramid part of the tent cloth on the top surface 21 (approximately 15 cm) is the same as the height of the approximately square pyramid part of the tent cloth on the four sides 22 to 25 (approximately 10 cm). meters). In this way, the tent cloth on the sides of both the outer tent 10 and the inner tent 20 can be stretched stably by expanding the center part in a convex shape, but the convex parts of the top surfaces 11 and 21 are made higher ( Specifically, the height (at least 1.5 times the height of the square pyramid on the sides) not only allows the tent to be expanded stably, but also allows sauna users to be large adult men. Even if there is, you will be able to enjoy the sauna while sitting on a chair with plenty of time in the sauna room.

In this way, the shape and size of the tent cloth on the side surfaces 22 to 25 other than the top surface 21 and the bottom surface 26 of the inner tent 20 are almost the same as the shape and size of the tent cloth on the side surfaces 12 to 15 and the bottom surface 16 of the outer tent 10. It is.
In addition, the gap space between the outer tent 10 and the inner tent 20 based on the difference in shape and size of the tent fabrics on the top surface 11 and the top surface 21, and the difference in the tent fabrics on the top surface 21 and side tents 22 to 25 of the inner tent 20, etc. An air layer is formed in the gap space between the outer tent 10 and the inner tent 20 that occurs due to slack or the like. The air layer in the gap functions as a heat retaining layer when using the sauna.

By having the above configuration, the sauna tent 1 according to the present embodiment is easy to carry and assemble, and can have a firm and stable structure. In addition, since the inner tent 20 is attached to the inner surface of the outer tent 10 via the attachment part so as to be suspended, the two tents do not come into close contact with each other, and the hanging of the suspended inner tent 20 causes the outer surface of the inner tent 20 and the outer tent to hang. An air layer (for example, the space 30 in FIG. 3, which will be described later) is created in a slight gap between the inner surfaces of the tent 10, and the air in the air layer is suitably warmed by the heat insulation effect of both tents, and the inner tent 20 and The three layers of the air layer and the outer tent 10 further enhance the heat insulation effect.

A plurality of attachment portions (not shown) for attaching the inner tent 20 are formed at the center of the inner surface of the tent cloth of the top surface 11 and four side surfaces 12 to 15 of the outer tent 10. The plurality of attachment portions are formed at positions corresponding to the plurality of attachment portions of the outer tent 10 on the outer surface of each tent cloth of the top surface 21 and four side surfaces 22 to 25 of the inner tent 20. The inner tent 20 can be expanded by attaching a plurality of attachment parts 211, 221, 231, etc. Examples of attachments that can be used include hooks, front release buckles, or side release buckles.

Further, for example, on the inner tent surface of the top surface 11, four side surfaces 12 to 15, and bottom surface 16 of the outer tent 10, a substantially rectangular parallelepiped or a substantially cube formed by the top surface 11, four side surfaces 12 to 15, and the bottom surface 16 may be formed. Attachment portions for attaching the inner tent 20 inside the outer tent 10 are also formed at the corner portions corresponding to the apexes of the inner tent 10 and at the central portions of the connecting sides, and at corresponding portions on the outer surface of the inner tent 20. There is. For example, the top surface 21 of the inner tent 20 includes a mounting section 211 at the center of the tent cloth and mounting sections 212 to 215 at the four corners of the tent cloth as mounting sections for attaching to the inner surface of the outer tent 10. has been done.

Further, the sauna tent 1 according to this embodiment is equipped with a window made of transparent vinyl material. In this embodiment, an inverted triangular window 18 is formed near the center top of the tent cloth on the side surface 13 of the outer tent 10, and the window portion 18 is covered with a curtain 181 made of the same material as the tent cloth on the side surface 13. I'm trying to do that. The curtain 181 can be rolled up and fixed to the outside of the tent, for example. Further, a window portion 28 made of a transparent vinyl material is provided at a position on the side surface 23 of the inner tent 20 that corresponds to the window portion 18 on the side surface 13 of the outer tent 10. Furthermore, a curtain 281 that can be rolled up and fixed in a roll manner is provided inside the tent of the window section 28. In this embodiment, only one pair of windows (windows 18 and 28) is provided, but there is no particular restriction on the number of windows, and there is no particular restriction on the location where the windows are formed. .

Here, in this embodiment, the tent cloth on the bottom surface 16 of the outer tent 10 is removably connected to the tent cloths on the four side surfaces 12 to 15 of the outer tent 10 using a fastener (not shown). . Further, the tent cloth on the bottom surface 26 of the inner tent 20 is removably connected to the tent cloths on the four side surfaces 22 to 25 of the inner tent 20 using a fastener 261. In this way, by making the tent cloth on the bottom surface 16 of the outer tent 10 and the tent cloth on the bottom surface 26 of the inner tent 20 removable with a zipper structure, the sauna tent 1 can be easily installed on a balcony, garden, etc. The bottom sheet can be easily removed and removed in the event of stains due to the user's sweat, and can be easily reattached after washing. The zipper also prevents water and insects from entering through the bottom of the tent.

FIG. 3 is a cross-sectional image diagram for explaining the multi-layer structure of the tent cloth of the sauna tent 1 according to an embodiment of the present invention. As an example, FIG. 3 is a diagram illustrating a cross section of the tent cloth on the side surface 12 of the outer tent 10 of the sauna tent 1 and the tent cloth portion on the side surface 22 of the inner tent 20. As shown in FIG. 3, the tent cloth on the side surface 12 of the outer tent 10 is sandwiched between a waterproof and moisture-proof sheet 12A located outside the tent, a heat insulation sheet 12B located inside the tent, and the waterproof and moisture-proof sheet 12A and the heat insulation sheet 12B. It has a three-layer structure including a heat retaining layer 12C. Similarly, the tent cloth on the side surface 22 of the inner tent 20 consists of a waterproof and moisture-proof sheet 22A located on the outside of the tent, a heat insulation sheet 22B located on the inside of the tent, and a heat retention layer 22C sandwiched between the waterproof and moisture-proof sheet 22A and the heat insulation sheet 22B. It is formed with a three-layer structure.

Regarding the structure of each tent fabric of the outer tent 10 and the inner tent 20 shown in FIG. 3, in more detail, the waterproof and moisture-proof sheets 12A and 22A are made of, for example, oxford fabric, and are resistant to temperature changes and humidity changes inside and outside the tent. In addition to being less susceptible to damage, it is also extremely strong and resistant. In addition, the heat insulating sheets 12B and 22B are aluminum heat insulating sheets woven with graphene material, and are used as the material inside the tent for both the outer tent 10 and the inner tent 20, and the graphene material has strong strength and heat conduction. It is possible to create thin sheets with excellent properties. In addition, since it uses an aluminum material, it can achieve a high heat shielding effect by reflecting radiant heat from the electric heater.

The tent cloth of the outer tent 10 and the inner tent 20 has a three-layer structure, with heat-retaining layers 12C and 22C filled with batting in the space sandwiched between the waterproof and moisture-proof sheets 12A and 22A and the heat-insulating sheets 12B and 22B. is formed, and the tent cloth is subjected to quilting processes Q1 to Q4 to form a plurality of lattice-like sections. In this embodiment, the tent fabrics of the outer tent 10 and the inner tent 20 each have a three-layer structure, but may have a multi-layer structure in order to obtain similar or better effects.
By structuring the tent cloth as described above, both the tent cloth of the inner tent 20 and the outer tent 10 can be made durable, and by being able to retain heat in each of the small sections formed, the entire cloth can be kept warm. The effect can be increased.

There are differences in size between the outer tent 10 and the inner tent 20, and differences between the tent cloth of the outer tent 10 (for example, the tent cloth of the side surface 12) and the tent cloth of the inner tent 20 (for example, the tent cloth of the side surface 22). Due to the bending of the tent cloth caused by attaching the outer tent 20 to the outer tent 10, an air layer in the gap (for example, a space 30 between the tent cloth on the side surface 12 and the tent cloth on the side surface 22) is formed.

In this way, in the outer tent 10 and inner tent 20 of the sauna tent 1, the top surfaces 11 and 21, the bottom surfaces 16 and 26, and the four tent cloths of the side surfaces 12 to 15 and 22 to 25 each form a closed space. are connected so that Moreover, each tent cloth is formed with a multilayer structure of at least three layers: a heat insulating sheet, a waterproof and moisture-proof sheet, and a heat-retaining layer sandwiched between the heat-insulating sheet and the waterproof and moisture-proof sheet. Further, an air gap space serving as a heat insulating layer is formed between the outer tent 10 and the inner tent 20.

In the present embodiment, on the side surface 12 of the outer tent 10, two wires extend from the connector 121 formed on the tent cloth on the side surface 12 toward both ends of the connecting side with the side surface 13 adjacent to the side surface 12. A fastener 127 is formed along the frames 124 and 125 to open and close a portion of the tent cloth up and down to form an entrance 17 through which a user enters and exits the sauna tent 1. Further, on the side surface 22 of the inner tent 20, a fastener 227 (not shown) is provided at a position corresponding to the fastener 127 of the outer tent 10 for opening and closing a part of the tent cloth on the side surface 22 up and down to form the entrance/exit 17. is formed. This entrance/exit 17 is an entrance/exit made of a tent cloth formed on the side surface 12 of the outer tent 10 and has a substantially triangular shape having an approximately "dog-shaped" end portion around the connecting side of the side surface 12 and the side surface 13 as an axis. portion 126, and an entrance/exit portion made of a tent cloth having a substantially triangular shape having a substantially “dog-shaped” end portion with the connecting side of the side surfaces 22 and 33 as an axis among the tent cloths of the side surface 22 of the inner tent 20. It has a double structure of 226.
In this way, in the sauna tent 1 according to the present embodiment, the entrance/exit 17 is configured by the entrance/exit parts 126, 127, so that the position of the frame, which is important as the framework of the tent, is avoided, and the position necessary for the user's access is avoided. By minimizing the size, it is possible to avoid a sudden drop in the sauna temperature as users come in and out.

FIG. 4 is an external view of the electric heater 2 of the tent sauna set according to one embodiment of the present invention. The electric heater 2 can be installed inside the sauna tent 1, and uses a 100 volt AC power source commonly used in general households. Further, the rated power supplied at this time is 1000 to 1500 watts. The operation panel of the electric heater 2 includes a temperature control dial 201 for adjusting the temperature in the sauna room by adjusting the temperature of a heating heater (not shown) located inside the electric heater 2, and a temperature control dial 201 for adjusting the temperature inside the sauna room. A timer dial 202 is provided to set the heating time and turn off the heater when the set time has elapsed. Further, a power cord 203 and an outlet 204 are provided for connecting the sauna power source from the place where the sauna tent 1 is installed to a household 100 volt outlet. Further, a wooden decoration 205 is made on the side of the electric heater 2 to enhance the design of the heater, thereby enhancing the sense of luxury and atmosphere compared to a sauna used at home or the like.

In this embodiment, a tent sauna set is realized that can provide a full-fledged sauna experience at a high temperature range of approximately 95 to 105° C. by heating with the electric heater 2 using a 100-volt outlet for general household use as described above. Therefore, we repeatedly produced and tested the sauna tent 1, and by limiting the size of the sauna space in the sauna tent 1, that is, the size (inner volume) of the inner tent 20, to 2.6 cubic meters or less, we achieved a temperature of approximately 95 to 105 °C. It was confirmed that this could be achieved.

In this embodiment, as described above, the frame size of the top surface 21 and bottom surface 26 of the inner tent 20 is approximately 100 cm (width: W) x approximately 100 cm (depth: D), and the frame sizes of the side surfaces 22 to 25 are The frame size is 100 cm (width: W) x approximately 135 cm (height: H), the height of the approximately square pyramid portion of the tent cloth on the top surface 21 is approximately 15 cm, and the four side surfaces The height of the substantially quadrangular pyramid part in tent fabrics 22 to 25 is about 10 centimeters. Therefore, the volume (inner volume) of the inner tent 20 in this case is approximately 1.58 cubic meters. On the other hand, in the outer tent 10, the height of the substantially square pyramid part of the tent cloth of the top surface 11 is about 20 cm, and the other parts are the same as the inner tent 20, so the volume of the outer tent 10 in this case is (Inner volume) is 1.60 cubic meters.
In addition, the frame size of the top surface 21 and bottom surface 26 of the inner tent 20 is approximately 130 cm (width: W) x approximately 130 cm (depth: D), and the frame size of the sides 22 to 25 is approximately 130 cm (width: W) x approximately 130 cm (depth: D). : W) x approximately 135 cm (height: H), the height of the approximately quadrangular pyramid part of the tent cloth on the top surface 21 is approximately 15 cm, and the height of the approximately square pyramid portion of the tent cloth on the four sides 22 to 25 is approximately When the height of the square pyramid part is about 10 centimeters, the volume (inner volume) of the inner tent 20 is about 2.6 cubic meters.

FIG. 5 is an image diagram for explaining changes in room temperature inside a sauna tent according to an embodiment of the present invention. In FIG. 5, the applicant has installed the sauna inside the sauna tent 1 (the inside of the inner tent 20, which is a closed space) in an environment of room temperature (approximately 15 to 25 degrees Celsius in this case) in the room or rooftop of a general household, etc. The temperature inside the sauna was measured when the electric heater 2 was installed and the power was turned on, and the temperature change over time is shown in a simplified graph. As shown in FIG. 6, the thermometer was installed on the tent side at the center of the top surface 21 inside the inner tent 20, which is the highest position in the sauna room, and the sauna temperature was measured. FIG. 6 is a diagram showing a photograph of a thermometer attached to the inside of the inner tent of the sauna tent according to an embodiment of the present invention. As shown in FIG. 6, the inner surface of the inner tent 20 is, as mentioned above, an aluminum heat insulating sheet woven with graphene material, and is quilted to form a plurality of lattice-like sections. I can see what's going on.

As shown in FIG. 5, the temperature in the sauna room rose to 100° C. in about 20 to 30 minutes at room temperature. Note that even if the outside temperature is within the normal temperature range, the higher the outside temperature, the faster the temperature will reach 100°C, and even if the outside temperature is low (for example, about 15°C), the temperature inside the sauna will reach 100°C in about 30 minutes. It rose to Furthermore, it was confirmed that after reaching 100°C, the temperature inside the sauna room rose to approximately 105°C at room temperature (see Fig. 6).

That is, the tent sauna set composed of the sauna tent 1 and the electric heater 2 according to the present embodiment has the structure of the inner tent 20 and the outer tent 10 as described above, and the inner volume of the inner tent 20 is 2.
