Description

[Technical Field]

[0001] The present invention relates to a sauna device that can be used in a home bathroom. [Background technology]

[0002] Conventional sauna equipment includes sauna stoves that use firewood or fuel.

[0003] As an example of a stove that does not use fire, there is a stove that uses an electric heater, as shown in Patent Document 1.

[0004] There are also private saunas for home use, such as those in Patent Document 2.

[0005] Patent Document 3 discloses an example of a heat generating agent that uses the same thermal reaction of calcium oxide, aluminum powder, and water as in the present invention. However, its volume and flat shape make it unsuitable for use in a sauna, where the goal is to release a large amount of high-temperature steam. Its use is limited to heating water, food, and beverages enclosed in a heating container along with a heat generating agent.

[0006] Other common home heating agents include those that use iron powder or oxidizable metals, such as hand warmers and those in Patent Document 4. However, these are not suitable for sauna use due to the amount of heat generated and steam generated, and are therefore different from heating agents that use calcium oxide.

[0008] To provide a sauna stove that secures space by utilizing the space of a bathroom, does not use fire or emit smoke so that it can be used safely in a bathroom, and does not use electricity so that there is no risk of electric shock even when it is placed near water. We also offer a heat generating pack that functions as a sauna stone, generates a large amount of steam, and is easy to handle with tongs when heated. [Means for solving the problem]

[0009] The thermal reaction between calcium oxide and water, which is a thermal reaction used in a heat generating agent such as a bento box, is utilized, the heat generating agent is packaged in a filter capable of filtering water and steam, and the heat generating agent pack is placed on a sauna stove having a tray with holes for pouring water over it, and the heat generating agent is generated in the bathroom. [Effects of the Invention]

[0010] By utilizing the space of the bathroom, no new space is required, and by not using fire, there is no need to worry about fire or carbon monoxide poisoning, or getting dirty with charcoal or soot, and there is no need to install a chimney.In addition, since no electricity is used, there is no need to worry about electric shock or malfunction due to water, and there is no need to have an outlet or electrical cable, so you can enjoy a sauna in your own bathroom at home. [Brief explanation of the drawings]

[0011] [Figure 1] 1 is an overall schematic diagram of the present invention; [Figure 2] An explanatory diagram of the sliding tray in the sauna stove of the present invention. [Figure 3] 1 is a schematic diagram of a heating pack of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] The main material of the heat generating pack (1) is calcium oxide, which is used in devices to warm bento boxes at train stations and in rice warmers used as disaster prevention goods. By mixing in aluminum powder, the rate and temperature of the heat reaction when it reacts with water becomes suitable for a sauna.

[0013] In order to react calcium oxide and aluminum powder with water, the calcium oxide and aluminum powder are wrapped in a filter that filters out water and water vapor (8), and by packaging it with a filter, the substance inside that mixes with water is less likely to leak out of the package, and therefore is less likely to flow down a drain, etc. This is the exothermic agent pack of the present invention.

[0014] When calcium oxide reacts with water, the volume inside the packaging increases, so a stretchable filter is even better. If the filter's effectiveness is impaired by expansion, leave a margin (9) to allow for expansion, or stack the filters without sewing them together and wrap them in a stretchable material even if it does not have a filtering effect.

[0015] The heat generating pack has a three-dimensional structure that mimics sauna stones, making it easy to grasp with tongs even when heated. A triangular shape like rice balls (Figure 3) is even more preferable, as it makes it easier to pack multiple packs in a staggered arrangement in a box when the product is made. Also, a three-dimensional shape reduces the contact area between the base and the tray, increasing the surface area for steam release and making it easier for steam to escape through the gaps when several packs are stacked on top of each other.With a flat shape, there is more surface area facing the tray or other packs, which means there is no place for the steam to escape and it becomes difficult for it to liquefy and be released into the air.

[0016] It is also possible to create a depression towards the center of the heat generating pack to make it easier for water to reach the center of the pack, or to create a shape that increases the surface area for emitting steam.

[0017] Use thermochromic dyes or thermochromic materials that change color with heat to visually determine whether the temperature is high. This allows you to visually confirm when it has cooled down and put it away. It is preferable to use a material that is black or gray to mimic sauna stones when it is at room temperature, and red when it is at a high temperature.

[0018] This heat generating pack reacts with water, causing it to heat up through a thermal reaction and generate high-temperature steam, thus acting as an actual sauna stone.

[0019] It would be nice to have types that mix flavors such as mugwort into the heat generating pack or packaging filter so that you can enjoy the aroma.

[0020] In addition, hydrogen is generated by the reaction of calcium hydroxide and aluminum, and breathing it in can be expected to have an antioxidant effect on the human body. However, there is a risk of explosion if hydrogen is brought close to a fire, so care must be taken to ensure the amount of hydrogen generated.

[0021] It would be even better if there was a system in place to collect these heat generating packs after use and recycle them by using the calcium aluminate in cement or by heating the calcium hydroxide at high temperatures to turn it back into calcium oxide.

[0022] For sauna stoves for heat generating packs, place an appropriate number of heat generating packs on the tray (2) and pour water over them like a loyly to induce a thermal reaction. Warm water is preferable to cold water in order to minimize the temperature drop of the heat generating packs.

[0023] The tray (2, 7) has numerous holes that allow water poured from above to drain downwards. The tray also has a box (5) that surrounds it on all four sides, preventing the heat pack from falling and allowing water to accumulate.

[0024] The tray with holes has a double structure, so that by pulling the sliding handle (4), one side can be slid to close all the holes (10). This allows the holes to be closed to prevent drainage and to distribute water throughout the pack. It can also be used to soak the pack in water to cool it down after use.

[0025] By incorporating germanium into materials such as the tray (2) of the sauna stove for the heat generating pack, the germanium will receive heat from the heat generating pack and emit far infrared rays, which is expected to warm the human body more effectively. The heat generating pack of the present invention may also contain germanium.

[0026] The sauna stove should have legs (6) and be tall enough to allow for easy handling of the heating packs, and this will allow the tray to be raised off the ground, allowing for smooth drainage and preventing the ground from overheating. It is also preferable for the stove to be foldable when not in use.

[0027] Sauna stoves are intended to be placed in the bathroom wash area, but care must be taken when placing them so as not to block the bathroom door or emergency evacuation routes.

[0028] It is advisable to install a handle (3) made of a highly insulating material so that the device can be moved even when the exothermic agent is heated.

[0029] If you fill the bathtub with water and use it as a cold bath, you can take a bath after the sauna, and you can respond calmly if you get burned or the bathroom becomes hotter than expected.

[0030] It is also advisable to divide the space with a shower curtain or other device to efficiently heat the sauna space. It is also a good idea to turn off or weaken the bathroom exhaust fan to prevent steam from escaping. [Example]

[0031] Use the heat pack and sauna stove for the heat pack in your home bathroom. [Example]

[0032] The heat generating pack and sauna stove for heat generating pack of the present invention can be used in sauna tents for outdoor use, etc. [Example]

[0033] This can be used as an alternative to mugwort steaming by closing the holes in the saucer of the sauna stove or by placing the heat pack in a large amount of water in a separate container such as a pot and heating it together with Chinese medicine or herbs. [Industrial Applicability]

[0034] The heat generating pack and sauna stove for heat generating pack of the present invention can be sold as products. They can also be rented along with sauna tents at outdoor facilities. [Explanation of symbols]
