Description

[Technical Field]

[0001] The present invention relates to an oxygen supply device, and more particularly to an oxygen supply device for supplying oxygen to a sauna room. [Background technology]

[0002] Conventionally, various configurations have been proposed for increasing the oxygen concentration in a sauna room in order to avoid the stuffiness felt in a sauna room where the temperature becomes relatively high. For example, in Patent Document 1, The structure of the sauna room is disclosed, which is equipped with a supply means for oxygen etc., so that the oxygen concentration is 21 to 30 vol %.

[0003] The document states that by using an oxygen concentration meter to accurately adjust the oxygen concentration in the sauna room to 21 to 30 vol%, stuffiness can be alleviated and the occurrence of fires caused by combustible materials can be effectively suppressed.

[0004] Furthermore, in Patent Document 2, A sauna room and an oxygen supply device for supplying oxygen into the sauna room; An oxygen concentration measuring device for measuring the oxygen concentration in the sauna room; An oxygen concentration control device that controls the oxygen concentration in the sauna room to 31 vol% or more by adjusting the amount of oxygen supplied by the oxygen supply device based on the oxygen concentration measured by the oxygen concentration measurement device. A sauna comprising:

[0005] The document states that increasing the oxygen concentration in a sauna room can increase the fat burning effect and improve the diet effect. In addition, in the example of this document, an oxygen cylinder is used as the oxygen supply device.

[0006] However, in these documents, although the oxygen concentration in the sauna room may be properly controlled, there is a risk that the humidity in the sauna room will decrease excessively if dry oxygen is supplied to the sauna room. In particular, in the example of Patent Document 2, the oxygen concentration is high and an oxygen cylinder is used as the oxygen supply device, so the decrease in humidity is thought to be more significant.

[0007] In this regard, Patent Document 1 takes some measures by providing a separate steam supply means for supplying mist-like steam, but this complicates the overall system configuration of the sauna, and inevitably increases costs. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-236765 [Patent Document 2] Registered Utility Model No. 3110472 Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made to solve the above problems, and aims to provide an oxygen supply device that can maintain the humidity in a sauna room with a simple configuration. [Means for solving the problem]

[0010] According to the present invention, the oxygen supply device comprises an oxygen production device for producing oxygen, and a container filled with water and having an opening at the top. Here, the container is placed in a sauna room, and oxygen is supplied from the bottom, and oxygen is also supplied to the sauna room from the opening.

[0011] Oxygen is supplied from the bottom of the container and also from the opening into the sauna room. The oxygen supplied from the bottom of the container passes upward as bubbles through the water filled inside. Therefore, the oxygen released from the opening contains water vapor.

[0012] In other words, by bubbling the water in the container with oxygen as a carrier gas, the oxygen carries water vapor from the opening into the sauna room. As a result, the oxygen supply device can maintain the humidity in the sauna room with a simple configuration. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, the mode for carrying out the invention will be described based on examples. [Example]

[0015] [Configuration of the Example] An oxygen supply device 1 according to an embodiment of the present invention is shown in FIGS. It should be noted that the following examples are merely illustrative and the present invention is not limited to the following examples.

[0016] The oxygen supply device 1 includes an oxygen production device 2 that produces oxygen, and a container 3 that is filled with water W inside. The container 3 is installed inside the sauna room, but the oxygen production device 2 may be installed inside or outside the sauna room.

[0017] The oxygen production device 2 is not particularly limited as long as it produces oxygen, and an optimum device can be used depending on the mode of use. As the oxygen production device 2, for example, a pressure swing adsorption type oxygen concentrator, a cryogenic separation type oxygen concentrator, a water electrolysis cell stack, or the like can be used.

[0018] The container 3 is cylindrical and has a bottom, and the upper end is sealed with a lid 7 having a number of openings 5 ​​. The container 3 is approximately 90 cm high and 25 cm in diameter and is made of a transparent material. Here, the material of the container 3 is not particularly limited, and may be made of resin such as polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyvinyl chloride (PVC), etc., or may be made of glass.

[0019] The container 3 is fixed on a rectangular base 8 having sides of approximately 35 cm. At the bottom of the container 3, there are provided a water supply valve 10 for supplying water to the container 3, a drainage valve 11 for draining water from the container 3, and an oxygen supply valve 12 for supplying oxygen into the container 3. The water supply valve 10 , the drain valve 11 , and the oxygen supply valve 12 are exposed to the inside of the base 8 .

[0020] Here, the water supply valve 10 is connected to a water supply pipe 14, the drain valve 11 to a drain pipe 15, and the oxygen supply valve 12 to the oxygen supply device 1 via an oxygen supply tube 16, respectively. Although FIG. 1 shows a state in which only the oxygen supply tube 16 is connected, it is possible for the oxygen supply device 1 to function as such by using a container 3 that is filled with water W in advance.

[0021] When supplying water, the drain valve 11 and the oxygen supply valve 12 are closed and the water supply valve 10 is opened, thereby starting the pouring of water W into the container 3 from the water supply pipe 14. Then, when the liquid level WL reaches a predetermined position in the container 3, the water supply valve 10 is closed, thereby maintaining the position of the liquid level WL.

[0022] During drainage, the water supply valve 10 and the oxygen supply valve 12 are closed and the drain valve 11 is opened, thereby starting drainage of water W from the container 3 to the drain pipe 15. When the liquid level WL reaches a predetermined position in the container 3, the position of the liquid level WL is maintained by closing the drain valve 11.

[0023] Furthermore, when oxygen is supplied, oxygen production device 2 is started, water supply valve 10 and drain valve 11 are closed, and oxygen supply valve 12 is opened, thereby supplying oxygen into container 3. The supplied oxygen is then released into the sauna room from opening 5.

[0024] The position of the liquid surface WL is not particularly limited, and can be set to an appropriate position depending on the situation. If the position of the liquid level WL is too low, the amount of water vapor released may be insufficient. Therefore, the height of the liquid level WL is preferably 50% or more of the height of the container 3. On the other hand, if the liquid level WL is too high, the liquid level WL may come into contact with the lid 7 when oxygen is released into the sauna room. Therefore, the height of the liquid level WL is preferably 90% or less of the height of the container 3.

[0025] The oxygen supply tube 16 has a portion that is higher than the liquid level WL in the container 3. The material of the oxygen supply tube 16 is not particularly limited, and an optimum material can be selected as appropriate. That is, the material of the oxygen supply tube 16 may be either a soft material or a hard material.

[0026] [Effects of the Example] The oxygen supply device 1 includes an oxygen production device 2 that produces oxygen, and a container 3 that is filled with water W and has an opening 5 at the top. Here, the container 3 is placed in a sauna room, and oxygen is supplied from the bottom, and oxygen is also supplied from the opening 5 into the sauna room.

[0027] Oxygen is supplied from the bottom of the container 3 and also from the opening 5 into the sauna room, so the oxygen supplied from the bottom of the container 3 passes upward as bubbles through the water filled inside. Therefore, the oxygen released from the opening 5 contains water vapor.

[0028] In other words, by bubbling the water W in the container 3 with oxygen as a carrier gas, the oxygen carries water vapor from the opening 5 into the sauna room. As a result, the oxygen supplying device 1 can maintain the humidity in the sauna room with a simple configuration even when oxygen is supplied.

[0029] Furthermore, the container 3 has a transparent portion through which the water W can be seen. This allows the supply of oxygen to be confirmed by the presence of bubbles, so even if the supply of oxygen stops, it can be immediately confirmed that the supply of oxygen has stopped.

[0030] Further, oxygen is supplied to the container 3 from the oxygen production device 2 via an oxygen supply tube 16, and the oxygen supply tube 16 has a portion that is higher than the liquid level WL in the container 3. As a result, the water W in the container 3 does not exceed the position corresponding to the liquid level WL of the oxygen supply tube 16, so that backflow of the water W into the oxygen supply device 1 can be prevented.

[0031] [Variations] Various modifications of the present invention are possible without departing from the spirit of the invention. In the embodiment, there is one container 3, but as shown in FIG. 3, there may be a plurality of containers 3. This allows for multiple oxygen supply positions, thereby reducing unevenness in the oxygen concentration distribution within the sauna room.

[0032] In the embodiment, the lid portion 7 is provided, but the lid portion 7 may not be provided. This allows water W to be poured from the upper end opening of the container 3 as well. Furthermore, the evaporation of water vapor is promoted, making it possible to maintain the humidity inside the sauna room.

[0033] In the embodiment, a water supply valve 10, a drain valve 11, and an oxygen supply valve 12 are used, but these valves can also be electromagnetic valves, and a control device can be used to configure the water W in the container 3 to be automatically replaced.

[0034] In the embodiment, oxygen is supplied from the bottom of the container 3, but it may be configured so that oxygen is supplied from the lower side of the container 3. The lower part of the container 3 refers to a portion that is 20% or less of the height of the container 3 from the bottom.

[0035] In the embodiment, the container 3 is cylindrical with a bottom, but this is not restrictive. The container 3 may have a polygonal shape with a bottom. In addition, although the entire container 3 is made of a transparent material in the examples, this is not a requirement. The entire container 3 may be made of metal, or may have only a partial transparent portion. [Explanation of symbols]
