Description

[Technical field]

[0001] The present invention relates to a tent sauna set and a sauna tent equipped with an electric heater. [Background technology]

[0002] In recent years, various outdoor products have been developed along with the popularity of outdoor activities. One of these products is sauna tents and sauna stoves that allow you to enjoy a sauna outdoors. Some of these sauna tents can be assembled, deployed, and carried around, and can be set up at campsites or parks, or even on the roof of a building to enjoy the feeling of being outdoors when you cannot go far away.

[0003] In order to create a high temperature sauna room of 100°C, such sauna tents often use sauna stoves equipped with combustion furnaces (Patent Document 1), or electric heaters that run on 200 volts of commercial three-phase AC power. Also, a tent sauna set has been disclosed in which a stove for heating stones is installed using a 100-volt household power source inside a one-person tent (Non-Patent Document 1).

[0004] [Patent Document 1] JP 2023-123239 A [Non-patent literature]

[0005] [Non-Patent Document 1] Niiro LLC, "Sauna at Home", [online], March 3, 2023, PR TIMES, [Searched October 25, 2023], Internet<URL:https: / / prtimes.jp / main / html / rd / p / 000000007.000078032.html> Summary of the Invention [Problem to be solved by the invention]

[0006] However, the tent sauna set disclosed in Patent Document 1 is designed so that exhaust smoke is generated from a stove that burns liquid fuel such as ethanol and is exhausted from a chimney attached to the stove, which limits its use not only inside buildings but also on the balconies and gardens of ordinary homes. 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 in a one-person tent, the temperature can only be expected to rise to about 80 to 95°C, which is insufficient as a sauna for enjoying high temperatures. In response to this, it is possible to consider using an electric heater with a 200-volt power supply, but since 200-volt power equipment is not available in ordinary homes, and even if it is available, the location is often limited, so that it is not possible to freely decide the location to set up the sauna within the ordinary home, and use in ordinary homes is also limited.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a tent sauna set and a sauna tent that can easily provide an authentic high-temperature sauna experience in an ordinary home, etc. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a tent sauna set comprising a sauna tent and an electric heater, the sauna tent comprising an inner tent that forms a closed space that is heated by the electric heater after being deployed, and an outer tent that is deployed on the outside of the inner tent, the inner tent being attached to the inside of the outer tent with a gap formed therebetween, the inner tent and the outer tent being connected so that the tent cloth on the top, bottom and at least one or more sides respectively form a closed space, each tent cloth being formed with a multi-layer structure of at least three layers consisting of an insulating sheet, a waterproof and moisture-proof sheet, and a heat-retaining layer sandwiched between the insulating sheet and the waterproof and moisture-proof sheet, the electric heater being capable of being installed inside the sauna tent, the rated power supplied from a general household 100V AC outlet being 1000 to 1500 watts, and the inner tent having an internal volume of 2.6 cubic meters or less.

[0009] In addition, in order to solve the above-mentioned problems, the present invention provides a sauna tent in which an electric heater can be installed inside, the sauna tent comprising an inner tent which forms a closed space heated by the electric heater supplied from a 100V AC outlet for general household use, and an outer tent which is stretched out on the outside of the inner tent, the inner tent being attached by forming a gap on the inside of the outer tent, the inner tent and the outer tent being connected so that the tent cloth on the top, bottom and at least one or more sides respectively form a closed space, each tent cloth being formed with a multi-layer structure of at least three layers consisting of an insulating sheet, a waterproof and moisture-proof sheet, and a thermal insulation layer sandwiched between the insulating sheet and the waterproof and moisture-proof sheet, and the internal volume of the inner tent is 2.6 cubic meters or less. Effect of the Invention

[0012] Hereinafter, a tent sauna set according to an embodiment of the present invention will be described with reference to the drawings. The tent sauna set according to an embodiment of the present invention is composed of a sauna tent 1 that can be used indoors in a general house or outdoors on a rooftop or in a garden, and an electric heater 2 that is installed inside the tent.

[0013] 1 is an external view of a sauna tent 1 according to one 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 deployed, and an outer tent 10 that is deployed outside the inner tent 20. The inner tent 20 is attached while forming an air gap inside the outer tent 10.

[0014] In this embodiment, the outer tent 10 is formed by connecting quadrilateral tent cloth pieces to form an approximately rectangular or cuboid shape, assuming that the tent cloth on the top surface 11, bottom surface 16 and four side surfaces 12 to 15 (side surfaces 14 and 15 are not shown in Figure 1 because they are the reverse side of sides 12 and 13). The side surface of the outer tent 10 may be made of a single tent cloth, such as a cylindrical surface, or may be made by connecting two or more pieces of tent cloth with multiple curved or flat surfaces. In the case of such a shape of the side surface, the shape of the top surface 11 and the bottom surface 16 will be such that they can be connected to form a closed space depending on the case.

[0015] FIG. 2 is an external view of the inner tent 20 of the sauna tent 1 according to one embodiment of the present invention. In this embodiment, the inner tent 20 is formed by connecting quadrilateral tent cloth pieces to form a substantially rectangular parallelepiped or cubic shape, assuming that the tent cloths of the top surface 21, bottom surface 26, and four side surfaces 22 to 25 (side surfaces 24 and 25 are not shown in FIG. 1 because they are the back side of the side surfaces 22 and 23) are flat, similar to the outer tent 10. The side surfaces of the inner tent 20 may also be formed of a single tent cloth piece, such as a cylindrical surface, or may be formed by connecting two or more pieces of tent cloth pieces having a plurality of curved or flat surfaces. In addition, the shapes of the top surface 21 and bottom surface 26 in the case of such shaped side surfaces are made to be shapes that can be connected to form a closed space according to each case. However, the inner tent 20 is attached to the inside of the outer tent 10 as described later, 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-retaining layer, it is desirable that the shape of the inner tent 20 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 cubic shape.

[0016] Here, four frames are arranged from the center toward the four corners on each of the tent cloths of the top surface 11 and the four side surfaces 12-15 of the outer tent 10, and the four frames are foldably connected to the tent cloths by a connector attached to the center of each tent cloth so as to open and close like an umbrella, and are formed integrally with the tent cloths. For example, a connector 111 is formed integrally with the center of the tent cloth of the top surface 11, and four frames 112-115 (frame 112 is not shown in FIG. 1) connected to the connector 111 in a foldable manner on the inside of the tent are arranged toward the four corners of the tent cloth of the top surface 11. Similarly, a connector 121 is formed integrally with the center of the tent cloth of the side surface 12, and four frames 122-125 connected to the connector 121 in a foldable manner on the inside of the tent are arranged toward the four corners of the tent cloth of the side surface 12. The same is true for the other side surfaces 13-15.

[0017] The material of the frame may be, for example, a non-metallic frame such as FRP or fiberglass, or a metallic frame such as duralumin or aluminum. The tent cloth is stretched by pulling the central portions of the tent cloths of the top surface 11 and the four side surfaces 12 to 15 of the outer tent 10 outward, and the outer tent 10 can be fixed in a stretched state by stretching all the tent cloths of the top surface 11 and the four side surfaces 12 to 15.

[0018] In addition, if the connectors 111, 121, etc. and the frame 112, etc. of the tent cloth of the top surface 11 and the four side surfaces 12 to 15 are attached to the tent cloth on the inside of the tent cloth so as not to be directly visible from the outside of the tent, the beauty of the appearance can be ensured. Also, as described later, since the outer tent cloth of the outer tent 10 is made of a sheet of Oxford cloth or the like that is durable and has waterproof and moisture-proof properties, by integrally forming the connectors 111, etc. and the frame 112, etc. on the inside of the tent cloth, the connectors 111, etc. and the frame 112, etc. are less susceptible to the effects of the external environment such as temperature, humidity, sunlight, and snowfall.

[0019] Here, when the outer tent 10 is in the expanded state, the tent cloth of the top surface 11 and the four side surfaces 12 to 15 of the outer tent 10 is pulled outward in a central portion thereof, so that the frames 112 to 115, 122 to 125, etc. unfold in the same manner as the ribs of an umbrella, and each tent cloth is expanded to form an approximately pyramidal convex surface.

[0020] For example, in this embodiment, the frame size of the top 11, sides 12-15, and bottom 16 of the outer tent 10 ("the size of the frame when the edge portions of each tent fabric are used as the frame": same below) is approximately 100 centimeters (width: W) by approximately 100 centimeters (depth: D) for the top 11 and bottom 16, and approximately 100 centimeters (width: W) by approximately 135 centimeters (height: H) for the sides 12-15. In addition, when the outer tent 10 is in an expanded state, the top surface 11 and the sides 12 to 15 each form a convex surface having an approximately quadrangular pyramid shape, and in this case, the height of the quadrangular pyramid of the top surface 11 is approximately 20 centimeters, and the height of the quadrangular pyramid of the sides 12 to 15 is approximately 10 centimeters.

[0021] On the other hand, the inner tent 20 is attached to the inside of the outer tent using connecting devices such as the top 11 and sides 12-15 of the outer tent 10, so that the frame sizes of the top 21, sides 22-25, and bottom 26 of the inner tent 20 after attachment are approximately 100 centimeters (width: W) x approximately 100 centimeters (depth: D) for the top 21 and bottom 26, and 100 centimeters (width: W) x approximately 135 centimeters (height: H) for the sides 22-25, which are almost the same as the frame sizes of the outer tent 10.

[0022] When the inner tent 20 is attached to the expanded outer tent 10, the top surface 21 and the side surfaces 22 to 25 each form a substantially quadrangular pyramid-shaped convex surface, and in this case, the height of the quadrangular pyramid of the top surface 21 is approximately 15 centimeters, and the height of the quadrangular pyramid of the side surfaces 22 to 25 is approximately 10 centimeters. That is, in this embodiment, in the outer tent 10, the height (approximately 20 centimeters) of the substantially quadrangular pyramid portion of the tent cloth of the top surface 11 is twice the height (approximately 10 centimeters) of the substantially quadrangular pyramid portion of the tent cloth of the four side surfaces 12 to 15. In addition, in the inner tent 20, the height (approximately 15 centimeters) of the substantially quadrangular pyramid portion of the tent cloth of the top surface 21 is 1.5 times the height (approximately 10 centimeters) of the substantially quadrangular pyramid portion of the tent cloth of the four side surfaces 22 to 25. In this way, the tent fabric on the sides of both the outer tent 10 and the inner tent 20 can be spread out stably by spreading the central portion in a convex shape, but by making the convex portions of the top surfaces 11, 21 higher (specifically, at least 1.5 times the height of the approximately square pyramid on the side), not only can the tent be spread out stably, but even sauna users who are large adult men can sit comfortably in their chairs inside the sauna room and enjoy the sauna.

[0023] In this way, the shape and size of the tent cloth of the sides 22 to 25 and bottom 26 other than the top surface 21 of the inner tent 20 are approximately the same as the shape and size of the tent cloth of the sides 12 to 15 and bottom 16 of the outer tent 10. Furthermore, air layers are formed in the gaps between the outer tent 10 and the inner tent 20 due to differences in the shapes and sizes of the tent fabric of the top surface 11 and the top surface 21, and in the gaps between the outer tent 10 and the inner tent 20 due to slackness of the tent fabric of the top surface 21 and the side tents 22 to 25 of the inner tent 20. The air layers in the gaps function as heat retaining layers when using the sauna.

[0024] With the above-mentioned configuration, the sauna tent 1 according to this embodiment is easy to carry and assemble, and can be constructed with a firm and stable structure. In addition, since the inner tent 20 is attached to the inside surface of the outer tent 10 by hanging it through the mounting parts, the two tents do not come into close contact with each other, and the hanging inner tent 20 creates an air layer (for example, space 30 in FIG. 3 described later) in the slight gap between the outside surface of the inner tent 20 and the inside surface of the outer tent 10, and the air in the air layer is appropriately warmed by the insulating and heat-retaining effect of both tents, and the insulating and heat-retaining effect is further enhanced by the three layers of the inner tent 20, the air layer, and the outer tent 10.

[0025] A plurality of attachment parts (not shown) for attaching the inner tent 20 are formed in the center of the inner surface of the tent cloth of the top surface 11 and each of the four side surfaces 12 to 15 of the outer tent 10. Then, a plurality of attachment parts 211, 221, 231, etc. formed in positions corresponding to the plurality of attachment parts of the outer tent 10 on the top surface 21 and each of the four side surfaces 22 to 25 of the inner tent 20 are attached to the plurality of attachment parts, so that the inner tent 20 can be deployed. Examples of attachments that can be used include hooks, front release buckles, and side release buckles.

[0026] Furthermore, for example, mounting parts for mounting the inner tent 20 inside the outer tent 10 are formed at corner portions and central portions of each connecting side that correspond to vertices of a substantially rectangular parallelepiped or substantially cube formed by the top surface 11, the four side surfaces 12-15 and the bottom surface 16 of the outer tent 10, and at corresponding portions on the outer surface of the inner tent 20. For example, the top surface 21 of the inner tent 20 is provided with a mounting part 211 in the center of the tent cloth and mounting parts 212-215 at the four corners of the tent cloth as mounting parts for mounting to the inner surface of the outer tent 10.

[0027] The sauna tent 1 according to this embodiment is provided with a window made of a transparent vinyl material. In this embodiment, a window portion 18 is formed in the shape of an inverted triangle near the upper center of the tent cloth on the side surface 13 of the outer tent 10, and the window portion 18 can be covered with a curtain 181 made of the same material as the tent cloth on the side surface 13. The curtain 181 can be rolled up and fixed on the outside of the tent, for example. In addition, 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 corresponding 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 on the inside of the tent of the window portion 28 is provided. In this embodiment, only a pair of window portions (window portions 18, 28) are provided, but there is no particular limit to the number of window portions, and there is no particular limit to the location of the window portions.

[0028] In this embodiment, the tent cloth on the bottom surface 16 of the outer tent 10 is detachably connected to the tent cloth on the four side surfaces 12 to 15 of the outer tent 10 using a fastener (not shown). Also, the tent cloth on the bottom surface 26 of the inner tent 20 is detachably connected to the tent cloth on the four side surfaces 22 to 25 of the inner tent 20 using a fastener 261. In this way, 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 can be removed using a fastener structure, so that when the sauna tent 1 is installed on a balcony or in a garden and becomes dirty due to sweat from a sauna user, the bottom sheet can be easily removed and replaced, and can be easily attached after washing. Also, the fastener can prevent water, insects, etc. from entering from the bottom of the tent.

[0029] FIG. 3 is a cross-sectional image diagram for explaining a multi-layer structure of the tent cloth of the sauna tent 1 according to one embodiment of the present invention. FIG. 3 is a cross-sectional image diagram of the tent cloth of the side 12 of the outer tent 10 of the sauna tent 1 and the tent cloth part of the side 22 of the inner tent 20. As shown in FIG. 3, the tent cloth of the side 12 of the outer tent 10 is formed in a three-layer structure of a waterproof and moisture-proof sheet 12A located on the outside of the tent, a heat insulating sheet 12B located on the inside of the tent, and a heat retaining layer 12C sandwiched between the waterproof and moisture-proof sheet 12A and the heat insulating sheet 12B. Similarly, the tent cloth of the side 22 of the inner tent 20 is formed in a three-layer structure of a waterproof and moisture-proof sheet 22A located on the outside of the tent, a heat insulating sheet 22B located on the inside of the tent, and a heat retaining layer 22C sandwiched between the waterproof and moisture-proof sheet 22A and the heat insulating sheet 22B.

[0030] Regarding the configuration of each tent fabric of the outer tent 10 and the inner tent 20 shown in Fig. 3, the waterproof and moisture-proof sheets 12A and 22A are made of, for example, Oxford cloth, which is not easily affected by temperature and humidity changes inside and outside the tent, and is very strong and durable. The heat insulating sheets 12B and 22B are aluminum-based heat insulating sheets woven with graphene material, and are used as the material on the inside of both the outer tent 10 and the inner tent 20, and the graphene material makes it possible to realize a thin sheet that is strong and has excellent thermal conductivity. In addition, since an aluminum-based material is used, a high heat shielding effect can be obtained by reflecting radiant heat from an electric heater.

[0031] The tent cloth of the outer tent 10 and the inner tent 20 is formed of a three-layer structure, with thermal insulation layers 12C, 22C filled with padding in the space between the waterproof and moisture-proof sheets 12A, 22A and the heat-insulating sheets 12B, 22B, and the tent cloth is quilted Q1 to Q4 to form a plurality of lattice-like sections. In this embodiment, the tent cloth of the outer tent 10 and the inner tent 20 is three-layered, but it may be further multi-layered in order to obtain the same or better effect. By constructing the tent cloth as described above, the tent cloth of both the inner tent 20 and the outer tent 10 can be made durable, and the heat retention effect of the entire cloth can be improved by being able to retain heat in each of the small compartments formed.

[0032] Between the tent cloth of the outer tent 10 (e.g., the tent cloth on side 12) and the tent cloth of the inner tent 20 (e.g., the tent cloth on side 22), an air layer (e.g., space 30 between the tent cloth on side 12 and the tent cloth on side 22) is formed due to the size difference between the outer tent 10 and the inner tent 20, and the bending of the tent cloth when the inner tent 20 is attached to the outer tent 10.

[0033] In this way, the outer tent 10 and the inner tent 20 of the sauna tent 1 are connected so that the tent cloths of the top surfaces 11, 21, bottom surfaces 16, 26, and four side surfaces 12-15, 22-25 form a closed space. Each tent cloth is formed with a multi-layer structure of at least three layers, including 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. Furthermore, a gap space of an air layer that serves as a heat-retaining layer is formed between the outer tent 10 and the inner tent 20.

[0034] In this embodiment, on the side 12 of the outer tent 10, a fastener 127 is formed along two frames 124, 125 extending from a connector 121 formed on the tent cloth of the side 12 toward both ends of the connecting edge between the side 12 and the adjacent side 13, for vertically opening and closing a portion of the tent cloth to form an entrance / exit 17 for users to enter and exit the sauna tent 1. On the side 22 of the inner tent 20, a fastener 227 (not shown) is formed at a position corresponding to the fastener 127 of the outer tent 10, for vertically opening and closing a portion of the tent cloth of the side 22 to form the entrance / exit 17. This entrance / exit 17 has a dual structure consisting of an entrance / exit section 126 made of the tent cloth of the side 12 of the outer tent 10, which has an approximately triangular shape with an end that is approximately "L-shaped" around the connecting edge of side 12 and side 13 as its axis, and an entrance / exit section 226 made of the tent cloth of the side 22 of the inner tent 20, which has an approximately triangular shape with an end that is approximately "L-shaped" around the connecting edge of side 22 and side 33 as its axis. In this way, in the sauna tent 1 of this embodiment, the entrance / exit 17 is composed of entrance / exit sections 126, 127, which avoids the position of the frame that is important as the framework of the tent and has a shape that minimizes the size required for users to enter and exit, making it possible to avoid a sudden drop in the sauna temperature as users enter and exit.

[0035] FIG. 4 is an external view of the electric heater 2 of the tent sauna set according to an 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 that is commonly used in ordinary households. The rated power supplied at this time is 1000 to 1500 watts. The control panel of the electric heater 2 is provided with a temperature adjustment dial 201 for adjusting the temperature of the heater (not shown) located inside the electric heater 2 to adjust the temperature inside the sauna room, and a timer dial 202 for setting the heating time of the heater and turning off the heater when the set time has elapsed. In addition, a power cord 203 and a socket 204 are provided for connecting the power source of the sauna to a 100-volt household socket from the place where the sauna tent 1 is installed. Furthermore, a wooden decoration 205 is created on the side of the electric heater 2 to enhance the design of the heater, enhancing the sense of luxury and atmosphere compared to saunas used at home, etc.

[0036] In this embodiment, a tent sauna set is realized that can provide a full-fledged sauna experience in a high temperature range of about 95 to 105°C by heating with an electric heater 2 that uses a 100-volt outlet for general household use as described above. For this purpose, the sauna tent 1 was repeatedly prototyped and tested, and it was confirmed that a temperature of about 95 to 105°C can be achieved by limiting the size of the sauna space in the sauna tent 1, i.e., the size (internal volume) of the inner tent 20, to 2.6 cubic meters or less.

[0037] In this embodiment, as described above, the frame size of the top surface 21 and bottom surface 26 of the inner tent 20 is about 100 centimeters (width: W) x about 100 centimeters (depth: D), the frame size of the side surfaces 22 to 25 is 100 centimeters (width: W) x about 135 centimeters (height: H), the height of the approximately square pyramid portion of the tent cloth of the top surface 21 is about 15 centimeters, and the height of the approximately square pyramid portion of the tent cloth of the four side surfaces 22 to 25 is about 10 centimeters. Therefore, the volume (internal volume) of the inner tent 20 in this case is about 1.58 cubic meters. On the other hand, the height of the approximately square pyramid portion of the tent cloth of the top surface 11 of the outer tent 10 is about 20 centimeters, and the other parts are the same as the inner tent 20, so the volume (internal volume) of the outer tent 10 in this case is 1.60 cubic meters. In addition, if the frame size of the top 21 and bottom 26 of the inner tent 20 is approximately 130 centimeters (width: W) by approximately 130 centimeters (depth: D), the frame size of the sides 22 to 25 is 130 centimeters (width: W) by approximately 135 centimeters (height: H), the height of the approximately square pyramid portion of the tent cloth of the top 21 is approximately 15 centimeters, and the height of the approximately square pyramid portion of the tent cloth of the four side panels 22 to 25 is approximately 10 centimeters, the volume (internal volume) of the inner tent 20 will be approximately 2.6 cubic meters.

[0038] FIG. 5 is an image diagram for explaining the transition of room temperature in a sauna tent according to one embodiment of the present invention. In FIG. 5, the applicant measures the temperature in a sauna room (inside the inner tent 20, which is a closed space) of a sauna tent 1 in a room or on a rooftop of a general home or the like under a room temperature (here, about 15 to 25° C.) environment, 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 of 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 a sauna tent according to one embodiment of the present invention. As shown in FIG. 6, the inner surface of the inner tent 20 is an aluminum-based heat insulating sheet woven with a graphene material as described above, and it can be seen that a plurality of lattice-shaped sections are formed by quilting.

[0039] As shown in Figure 5, the temperature inside the sauna rose to 100°C in approximately 20 to 30 minutes at room temperature. Even within the room temperature range, the higher the outside temperature, the faster the temperature reached 100°C. Even when the outside temperature was low (for example, about 15°C), the temperature inside the sauna rose to 100°C in approximately 30 minutes. It was also confirmed that after reaching 100°C, the temperature inside the sauna rose to approximately 105°C at room temperature (see Figure 6).

[0040] That is, the tent sauna set consisting of the sauna tent 1 and electric heater 2 according to this embodiment has the above-mentioned structure of the inner tent 20 and outer tent 10, and the inner tent 20 has an internal volume of 2.6 cubic meters or less, so it is easy to assemble and transport, and can be easily deployed, installed, and powered in an ordinary home, providing users with a suitable high-temperature sauna experience. With this easily disassembled and portable home sauna for 1 to 2 people, a high-temperature sauna room of 95 to 105°C can be created in about 20 to 30 minutes at room temperature with an electric heater that uses a home 100 volt power source.

[0041] Furthermore, a larger sauna space is better for two adults to comfortably enjoy the sauna, but a smaller sauna space is preferable in order to create a high temperature sauna room of 95°C or higher using an electric heater 2 that uses a household 100-volt power source. In addition, by installing a temperature sensor directly on or near the thermometer and linking it to the electric heater 2, it is possible to automatically adjust the heating time and temperature of the electric heater 2, allowing users to maintain a constant temperature inside the sauna room.

[0042] 7 is an external view of a sauna tent 1 according to another embodiment of the present invention. In the sauna tent 1 according to this embodiment, the inner tent 20 is the same as that of the above embodiment, but the tent cloth of the bottom surface 16 of the outer tent 10 is not connected to the sides 12 to 15 by a fastener, but the tent cloth of the bottom surface 16 is connected to the tent cloth of the four sides 12 to 15 of the outer tent 10 in a roll-up manner. In this case, the tent cloth of the bottom surface 16 is detachably connected to the tent cloth of the sides 12 to 15 by a connector such as a front release buckle or a side release buckle. For example, the bottom surface 16 of the outer tent 10 is connected to the side surfaces 12 and 13 at a corner (first corner) by connectors 16a and 16e, to the side surfaces 11 and 12 at a corner (second corner) by connectors 16c and 16d, and to the vicinity of the middle between the first corner and the second corner by connector 16b. 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 easily removable, when the sauna tent 1 is set up on a balcony or in a garden and becomes dirty due to sweat from sauna users, the bottom sheet can be easily removed and replaced, and can be easily attached after washing. Also, by making it a roll-up type, it is possible to prevent water, insects, etc. from entering from the bottom of the tent.

[0043] In addition, the waterproof and moisture-proof sheets of the outer tent 10 and the inner tent 20 of the sauna tent 1 in this embodiment are made of Oxford fabric, but polyester fiber or other types of sheets can be used as long as they provide similar waterproof, moisture-proof, or water-repellent properties.
