Description

[Technical field]

[0001] The present invention relates to a portable sauna system that can be carried by a user, for example. [Background technology]

[0002] Traditionally, firewood-fueled saunas have been used, but because firewood-fueled saunas pose the risk of carbon monoxide poisoning from burning firewood, gas-fueled saunas, which are easier to burn completely, are also used. This gas-fuel sauna is configured to use, for example, a "sauna heater" that mixes gas with fresh air in a burner and burns the gas (for example, Patent Document 1, etc.). Regarding such gas-fueled saunas, there is a demand not only for them to be used as "stationary gas-fueled saunas" that are installed in a predetermined location, but also as portable gas-fueled saunas. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Application No. 64-34024 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even in the case of a "portable gas-fueled sauna," a gas supply is required, so there is an issue that the locations where the sauna can be installed are limited to places where city gas, etc. is available.

[0005] Therefore, an object of the present invention is to provide a portable sauna system that uses gas fuel, which is safer than firewood fuel, and that is not restricted in where it can be installed.

[0006] According to the present invention, the above-mentioned object is achieved by a portable sauna system comprising: a foldable sauna tent; a sauna gas combustion device arranged within the sauna tent; and a removable portable gas cylinder for supplying gas to the sauna gas combustion device, wherein the sauna gas combustion device comprises a cylinder attachment section for attaching the portable gas cylinder, a gas burner section for burning gas, a combustion air intake section for taking in combustion air to be mixed with the gas burner, an exhaust gas conveying section for transporting combustion gas after combustion and radiating heat into the sauna tent, and a gas exhaust section for discharging the combustion gas transported by the exhaust gas conveying section, wherein the combustion air intake section, the cylinder attachment section and the gas exhaust section are arranged facing the outside of the sauna tent, and the ventilation path between the combustion air intake section and the gas exhaust section is a closed exhaust path that has no opening toward the inside of the sauna tent.

[0007] According to the above-mentioned configuration, the portable sauna system does not use city gas or the like, but receives gas supply from a detachable portable gas cylinder. Therefore, even if city gas or the like is not available at the location where the sauna tent is set up, the portable sauna system can be used by using a portable gas cylinder. Furthermore, according to the above configuration, the sauna-like gas combustion device placed inside the sauna tent has a ventilation path between its combustion air intake section and gas exhaust section which is a closed exhaust path that has no opening toward the inside of the sauna tent. This makes it possible to prevent combustion gases and the like from flowing into the sauna tent, making it a highly safe portable sauna system. Furthermore, according to the above configuration, the cylinder attachment section is positioned facing the outside of the sauna tent, so the portable cylinder can be attached and detached outside the sauna tent, preventing gas or the like from being accidentally discharged into the sauna tent, making this a highly safe portable sauna system.

[0008] Preferably, the portable sauna system is characterized by comprising an electrically powered device and a thermoelectric unit for driving the electrically powered device.

[0009] According to the above configuration, even if the portable sauna system is equipped with electrically powered equipment such as a blower, the electrically powered equipment can be powered by the electricity generated in the thermoelectric unit without the need for an external power supply or batteries, etc. This makes it possible to install the portable sauna system anywhere without having to consider external power supplies, etc.

[0010] Preferably, the portable sauna system is characterized in that the electrically powered device is a blower, the blower being located at at least one of the combustion air intake section or the gas exhaust section.

[0011] According to the above-mentioned configuration, by disposing the blower in the combustion air intake section, the intake of air during combustion by the gas burner can be promoted, and the combustion characteristics can be improved. Furthermore, disposing a blower at the gas exhaust section promotes exhaust from the gas exhaust section, resulting in a safer exhaust system. In particular, in saunas that use gas, it is preferable to have a fan installed for forced exhaust in case of incomplete combustion of the gas, but a power source is required to operate this fan, and the fan could not be operated unless the location had access to a power source, etc. Also, if batteries were used as the power source, users had to carry the batteries with them, which was inconvenient for them. In this regard, according to the above-mentioned configuration, the blower can be used without worrying about an external power source, etc., and users can enjoy the sauna with peace of mind.

[0012] Preferably, the portable sauna system is characterized in that the electrically powered device is a blower, and the blower is positioned on the side of the sauna gas combustion apparatus facing the interior of the sauna tent.

[0013] According to the above configuration, by placing the blower on the side of the sauna gas combustion device facing the inside of the sauna tent, air inside the sauna tent can be circulated, improving the temperature uniformity inside the sauna tent.

[0014] Preferably, the portable sauna system is characterized in that an airflow changing section is disposed within the exhaust gas conveying section.

[0015] According to the above-mentioned configuration, since an airflow changing section such as a baffle plate is disposed in the exhaust gas conveying section, the efficiency of heat recovery and heat dissipation in the exhaust gas conveying section is improved. Effect of the Invention

[0016] As described above, the present invention has the advantage of being able to provide a portable sauna system that utilizes gas fuel, which is safer than firewood fuel, and that is not restricted in where it can be installed. [Brief description of the drawings]

[Diagram 5] 2 is a schematic perspective view showing a thermoelectric module 114 of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are imposed thereon. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is limited thereto.

[0019] (Main components of portable sauna system 1) FIG. 1 is a schematic diagram showing the main configuration of a portable sauna system 1. As shown in FIG. 1, the portable sauna system 1 includes a foldable sauna tent, for example, a portable sauna tent 10, a sauna gas combustion device, for example, a sauna stove 100, that is placed within the portable sauna tent, and a detachable portable gas cylinder, for example, a cassette gas cylinder 200, for supplying gas to the sauna stove 100.

[0020] (Portable sauna tent 10) FIG. 2 is a schematic perspective view of the portable sauna tent 10 of FIG. The portable sauna tent 10 has a foldable structure, and when assembled, as shown in Figure 2, a sauna stove 100 can be placed inside and users can enjoy a sauna inside. The portable sauna tent 10 also has a door 11 that can be opened and closed on the entire surface, and users can enter the portable sauna tent 10 by opening this door 11, and the portable sauna tent 10 also has a window 12 that can be opened and closed.

[0021] The size of this portable sauna tent 10 is, for example, 180 cm wide x 180 cm deep x 170 cm high, and weighs approximately 7.2 kg. The material of the portable sauna tent 10 is selected to be, for example, a highly heat-resistant polyester or nylon material that is resistant to high temperatures and humidity and is suitable for a sauna environment. It is also preferable to provide a waterproof coating on the inside of the portable sauna tent 10.

[0022] (200 cassette gas cylinders) FIG. 3 is a schematic cross-sectional view showing the internal structure of the cassette gas cylinder 200 of FIG. As shown in FIG. 3, the cassette gas cylinder 200 contains liquefied petroleum gas (LP gas, LPG) such as butane, isobutane, or propane in both liquid and gaseous states. Since the gas pressure is higher than atmospheric pressure, gas can be extracted from the cassette gas cylinder 200. In addition, butane and propane, which are the main components of LP gas, are gases at room temperature, but have the property of becoming liquid when stored in the cassette gas cylinder 200 and subjected to high pressure.

[0023] In addition, when gas is stored in the cassette gas cylinder 200, it is not filled to the brim, but always leaves some space when filling it. When this happens, some of the liquid gas evaporates and turns into gas, filling the empty space. In the case of butane gas, at normal temperature of 20 degrees, a pressure of approximately twice the atmospheric pressure is applied from the inside to the outside.

[0024] As shown in FIG. 3, there is a thin tube at the outlet of the cassette gas cylinder 200, and this tube is bent at a right angle inside the canister, as shown in FIG. In addition, there is a notch in the top of the cassette gas cylinder 200, and when it is connected to the sauna stove 100 with this notch positioned at the top, the bent tube inside the cassette gas cylinder 200 is exposed to gaseous gas rather than liquid gas. When the outlet of the tube is opened in this state, the high internal pressure causes the LP gas to be forced out into the sauna stove 100.

[0025] In this embodiment, for example, three cassette gas cylinders 200 are used.

[0026] (Sauna Stove 100) As shown in FIG. 1, the sauna stove 100 of this embodiment has a gas cylinder mounting section 101, for example, which is a cylinder mounting section for mounting a gas cylinder 2000, and a gas combustion section . As shown in FIG. 1, the gas combustion section 102 has, for example, a gas burner 103 which is a gas burner section for burning gas, and also has an adjustment knob 104 for adjusting the output of the gas burner 103.

[0027] The sauna stove 100 also has a combustion air intake section 105 that takes in combustion air to be mixed in the gas burner 103, and this combustion air intake section 105 is equipped with an intake fan 106, which is an example of an electrically powered device or blower.

[0028] As shown in FIG. 1, the sauna stove 100 has a heat storage material 107 and a steam structure 108, and also has an exhaust gas transport section, such as an exhaust duct 109, which transports the combustion gas after combustion and dissipates heat into the portable sauna tent 10. The exhaust duct 109 is provided with a plurality of baffle plates 110, for example, which are airflow changing sections.

[0029] The sauna stove 100 has a gas exhaust section, for example, a gas exhaust section 111, which exhausts the combustion gas transported by the exhaust duct 109, and the gas exhaust section 111 is equipped with an exhaust fan 112, which is an example of an electrically powered device or a blower.

[0030] In addition, the sauna stove 100 has an internal tent fan 113, which is an example of an electrically powered device or blower, a thermoelectric unit for driving the internal tent fan 113, for example a thermoelectric module 114, and sauna stones 115, etc.

[0031] Below, each component of the sauna stove 100 will be explained in order. (Cassette gas cylinder attachment part 101) As shown in FIG. 1, the cassette gas cylinder mounting portion 101 according to this embodiment is configured so that three cassette gas cylinders 200 can be mounted at the same time. This makes it possible for the temperature to change as shown in FIG. However, the present invention is not limited to the case where three can be attached, and four may be attached, or a single number or any other multiple number may be attached.

[0032] In addition, since the cassette gas cylinder attachment section 101 is positioned facing the outside of the portable sauna tent 10, the cassette gas cylinder 200 can be attached and detached outside the portable sauna tent 10, preventing gas or the like from being accidentally discharged into the portable sauna tent 10, making the portable sauna system 1 highly safe.

[0033] (Combustion air intake 105) As shown in FIG. 1, the combustion air intake section 105 has an intake opening facing the outside of the portable sauna tent 10 to supply air to the gas combustion section 102 in which the gas burner 103 is arranged. In addition, as shown in FIG. 1, the combustion air intake section 105 of this embodiment is equipped with an intake fan 106, and is configured to promote air intake during combustion by the gas burner 103 and improve the combustion characteristics of the gas burner 103.

[0034] (Gas combustion section 102) As shown in FIG. 1, the gas combustion section 102 includes a gas burner 103 connected to the cassette gas cylinder mounting section 101 therein. (Gas Burner 103) The gas burner 103 is configured to receive gas from, for example, three cassette gas cylinders 200 and air from a combustion air intake section 105, mix these and perform combustion. In this embodiment, for example, there are three gas burners 103, and the combustion amount of each gas burner 103 is 2,000 Kcal / Hr, with the total of the three being a maximum of 6,000 Kcal / Hr.

[0035] FIG. 4 is a graph showing the temperature change inside the portable sauna tent 10 when one (2,000 Kcal / Hr) to three (6,000 Kcal / Hr) gas burners 103 according to this embodiment are used. As shown in FIG. 4, when three gas burners 103 are used, the sauna's target temperature of 80 degrees is reached in just 15 minutes. In this way, as shown in FIG. 1, when the cassette gas cylinder 200 and the three gas burners 103 are used, the portable sauna system 1 becomes extremely user-friendly for the user.

[0036] (Adjustment knob 104) The inside of the portable sauna tent 10 of the sauna stove 100 is provided with an “adjustment knob 104” for adjusting the output of the gas burner 103. By operating this adjustment knob 104 , the user can adjust the output of the gas burner 103 .

[0037] (Heat storage material 107) As shown in FIG. 1, the heat storage material 107 is arranged in the gas combustion section 102 and is configured to store heat from the gas burner 103, thereby improving the temperature rise efficiency inside the portable sauna tent 10.

[0038] (Steam Structure 108) As shown in FIG. 1, the steam structure 108 is disposed in the gas fuel section 102, and the water contained in the steam structure 108 is heated by the heat in the gas fuel section 102 to become water vapor, thereby generating so-called "steam."

[0039] (Exhaust Duct 109) The exhaust duct 109 shown in FIG. 1 is configured to transport the air heated by the gas burner 103 and to recover and dissipate heat. In this embodiment, in order to optimize heat recovery, heat dissipation, and the like, exhaust duct 109 has an S-shape, but the present invention is not limited to this and other shapes may be used.

[0040] Further, in order to optimize heat recovery and radiation, not only the structure of exhaust duct 109 itself but also the surface of exhaust duct 109 may be coated with a heat radiation paint. Furthermore, as shown in FIG. 1, a baffle plate 110 may be disposed inside the exhaust duct 109. By adopting these configurations, heat dissipation can be improved and the temperature inside the portable sauna tent 10 can be raised in a shorter period of time.

[0041] (Gas exhaust section 111) As shown in FIG. 1, the gas exhaust section 111 has an opening at one end that is positioned facing outside the portable sauna tent 10, and the other end is connected to the exhaust duct 109 so as to exhaust the exhaust gas in the exhaust duct 109 outside the portable sauna tent 10. Moreover, gas exhaust section 111 of this embodiment is provided with exhaust fan 112, which promotes exhaust and provides a safer exhaust system.

[0042] (Inner tent fan 113) As shown in FIG. 1, the tent interior fan 113 is installed on the surface of the gas stove 100 or the surface of the gas exhaust part 111 arranged inside the portable sauna tent 10. By installing this tent interior fan 113, intake air circulation within the portable sauna tent 10 is promoted, improving the temperature uniformity within the portable sauna tent 10.

[0043] (Thermoelectric module 114) FIG. 5 is a schematic perspective view showing the thermoelectric module 114 of FIG. As shown in FIG. 5, a thermoelectric module 114 that generates power includes a thermoelectric conversion element 114a and a power supply cord 114b that transmits the power generated by the thermoelectric conversion element 114a. As shown in FIG. 5, the thermoelectric conversion element 114a has a high temperature portion (hot surface) 114aa and a low temperature portion (cold surface) 114ab.

[0044] The thermoelectric conversion element 114a includes a Seebeck element (semiconductor element) that generates a thermoelectromotive force by utilizing the Seebeck effect. Such a thermoelectric conversion element 114a is formed by bonding an n-type semiconductor and a p-type semiconductor together, and when heated, carriers move across the boundary between the different semiconductors, generating an electromotive force.

[0045] In this case, if the potential difference of the current is V and the temperature difference between the high temperature and low temperature parts is ΔT, then V=aΔT (a is the Seebeck coefficient) holds, and the greater the temperature gradient between the high temperature portion 114aa and the low temperature portion 114ab, the greater the generated electromotive force.

[0046] Therefore, by using the thermoelectric module 114, it is possible to use electric power without relying on an external power supply, a battery, or the like. Specifically, the tent internal fan 113, etc. can be used even in places where there are no power facilities, etc., making the portable sauna tent 10 safer to use.

[0047] In this embodiment, a thermoelectric module 114 shown in FIG. 5 is disposed in the gas combustion section 102 as shown in FIG. Specifically, the high temperature section 114aa is disposed inside the gas combustion section 102, and the low temperature section 114ab is disposed outside the gas combustion section 102. By being arranged in this manner, the thermoelectric module 114 can generate power efficiently and supply driving power to the intake fan 106, the tent interior fan 113, and the exhaust fan 112 in FIG.

[0048] (Sauna Stone 115) The sauna stones 115 are volcanic rocks that are absorbent and have the effect of generating steam. When a user pours water onto the sauna stones 115 inside the portable sauna tent 10, the humidity inside the portable sauna tent 10 increases, allowing the user to enjoy this condition.

[0049] The above is an explanation of each component of the sauna stove 100 in FIG. 1. Below, the "self-supply and exhaust system" that is a feature of the sauna stove 100 of this embodiment will be explained. In other words, the sauna stove 100 has a ventilation path between the combustion air intake section 105 and the gas exhaust section 111, which is a closed exhaust path that does not have an opening toward the inside of the portable sauna tent 10, for example, a self-supply and exhaust type. Air taken in through the combustion air intake 105 for combustion is led to the gas combustion section 102, where it is mixed with gas and burned in the gas burner 103, and the heated air is radiated into the portable sauna tent 10 through the exhaust duct 109. The gas after combustion is then exhausted to the outside through the gas exhaust section 111, but the ventilation path from the intake to the exhaust is a "closed system," with no openings toward the inside of the portable sauna tent.

[0050] Because the sauna stove 100 of this embodiment has this type of "self-supply and exhaust system" configuration, it is possible to prevent combustion gases and the like from flowing into the portable sauna tent 10, resulting in a highly safe portable sauna system 1.

[0051] (Example of portable sauna system 1 in operation) The operation will be explained below using an example in which a user folds up the portable sauna tent 10 of the portable sauna system 1 of this embodiment and uses the portable sauna system 1 in a location where city gas, power supply, etc. are not available.

[0052] First, when the user arrives at his / her destination, he / she assembles the "portable sauna tent 10" that he / she has brought folded, as shown in FIG. 2, and installs the "sauna stove 100" inside it. In this case, the opening of the combustion air intake section 105 of the sauna stove 100 in FIG. 1, the opening of the cassette gas cylinder mounting section 101, and the opening of the gas exhaust section 111 are positioned so as to protrude from the portable sauna tent 10.

[0053] Next, the user loads the three cassette gas cylinders 200 he or she has brought with him or her into the cassette gas cylinder loading section 101 . In this way, the portable sauna system 1 according to the present embodiment allows one to enjoy a sauna even in places where city gas or the like cannot be used. Furthermore, in this embodiment, since the gas cylinder attachment section 101 is positioned facing the outside of the portable sauna tent 10, the cassette gas cylinder 200 can be attached and detached outside the portable sauna tent 10, and gas or the like will not be accidentally discharged into the portable sauna tent 10, making the portable sauna system 1 highly safe.

[0054] Next, the gas burner 103 is ignited to combust the gas in the cassette gas cylinder 200 . Then, by using three gas burners 103 with 2000 Kcal / Hr each, the target temperature of 80 degrees is reached in 15 minutes as shown in FIG. In this way, by using the cassette gas cylinder 200 instead of city gas or the like, the temperature inside the portable sauna tent 10 can be quickly raised to a temperature suitable for sauna use.

[0055] In addition, while the gas burner 103 is burning in the gas combustion section 102 of the sauna stove 100, the intake fan 106 provided in the combustion air intake section 105 operates. This can promote air intake during combustion by the gas burner 103, and improve the combustion characteristics of the gas burner 103.

[0056] The intake fan 106 is powered by the power from the thermoelectric module 114, so no external power supply or batteries are required, and users can enjoy the sauna anywhere without having to worry about the power source.

[0057] Next, the air heated by the gas burner 103 in the gas combustion section 102 is stored in the "heat storage material 107" arranged in the gas combustion section 102, thereby improving the temperature rise efficiency inside the portable sauna tent 10. In addition, a "steam structure 108" is also disposed in the gas combustion section 102, so that steam can be generated more effectively within the portable sauna tent 10.

[0058] The air heated by the gas combustion section 102 is guided to the exhaust duct 109. The exhaust duct 109 is bent in an S-shape and has a baffle plate 110 disposed therein, so that the heat dissipation can be improved more efficiently and the temperature inside the portable sauna tent 10 can be raised in a shorter time.

[0059] In addition, in this embodiment, an internal tent fan 113 is arranged on the outer surface of the portable sauna tent 10 side corresponding to the exhaust duct 109 of the sauna stove 100. As a result, the fan 113 promotes intake air circulation within the portable sauna tent 10, improving the temperature uniformity inside the tent 10.

[0060] The fan 113 inside the tent is powered by the power from the thermoelectric module 114, so no external power supply or batteries are required, and users can enjoy the sauna anywhere without having to worry about the power source.

[0061] In addition, while the gas burner 103 is burning in the gas combustion section 102 of the sauna stove 100, the exhaust fan 112 provided in the gas exhaust section 111 operates. The exhaust fan 112 promotes exhaust, making the exhaust system safer. The exhaust fan 112 is driven by power from the thermoelectric module 114, so no external power supply or batteries are required, and users can enjoy the sauna anywhere without having to worry about the power source.

[0062] As described above, the sauna stove 100 of this embodiment is of the "self-supply and exhaust type," so that users inside the portable sauna tent 10 can enjoy a sauna in safety. In addition, in this embodiment, users can easily enter and exit the portable sauna tent 10 by opening and closing the door 11, and users inside the portable sauna tent 10 can adjust the output of the gas burner 103 by operating the adjustment knob 104.

[0063] Additionally, users can use "sauna stones 115" to increase the humidity inside the portable sauna tent 10 as needed.

[0064] As described above, the portable sauna system 1 according to the present embodiment allows one to safely and easily enjoy a sauna even in places where city gas, an external power source, or the like cannot be used.

[0065] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or arbitrarily combined in a manner different from the above. For example, in the present embodiment, the thermoelectric module 114 or the like is used as the power source, but the present invention is not limited to this, and for example, a portable power source such as a small battery may be used.
