Description

[Detailed Description of the Invention] “Industrial Field of Application The present invention relates to a gas-fired infrared radiation sauna device.

Prior Art and Problems Recently, sauna bathing has become widespread for the purpose of improving health, and is becoming popular not only for commercial use but also for home use.

Conventional sauna equipment is generally a convection type using an electric heater, but infrared radiation sauna heaters are being installed in some saunas.

Furthermore, sauna devices that heat the human body by generating infrared rays using gaseous fuel have become known in Japanese Patent Publication No. 59-21913, Japanese Patent Publication No. 59-21927, etc., and are gradually being used.

However, all of the above-mentioned systems are aimed at relatively large-scale sauna equipment that is used to construct a sauna room and install equipment at a construction site.

In response, there is a need to develop a gas-fired infrared radiation sauna device with a structure that allows the sauna room to be manufactured in a factory and easily assembled at the installation site, like a small home sauna that uses electricity as a heat source. If such a device could be developed, gas-fired infrared radiation sauna devices would become even more popular due to the simplification of on-site construction and reduction of construction costs. The equipment installed outside the sauna room, such as the supply of fuel and air to the burner, the exhaust system, and various control equipment, is complicated.
The problem was that it was difficult to summarize it compactly.

The present inventor first developed a gas-fired infrared radiation device that addresses the above-mentioned conventional problems and published Utility Model Application No. 59-162174 (see Utility Model Application No. 61-77030).
However, this invention has been further improved to make it more effective for the human body, and irradiates a larger amount of infrared rays to the parts of the human body that require heating, and to the parts that require sweating. It is a more comfortable and energy-saving sauna device that allows sufficient sweating to be achieved in areas that require sweating even if the temperature of the room is lower than conventional ones, and it also makes the sauna outdoor equipment, which is unique to sauna devices that use gaseous fuel, safer. It is an object of the present invention to provide a sauna device having a structure that can be stored in a smaller space and that can simplify on-site construction at the installation site.

Means for Solving the Problems The present invention is a sauna room in which multiple people (2 or more
A seat for up to 6 people) is provided, an entrance is provided on either the left or right side walls, and an infrared emitting device is provided on the wall facing the seat. A horizontal infrared radiation tube that communicates a plurality of substantially horizontal metal tubes arranged at a height position that emits infrared rays between approximately the waist and shoulders of a person, and one or both of the left and right horizontal infrared radiation tubes. It consists of a rising infrared radiation tube whose upper end is connected to the end and which rises from near the floor surface, and the lower part of the horizontal infrared radiation tube installation location is insulated and partitioned from the sauna room, and this partition is used for the combustion of gaseous fuel. It is characterized by a machine room that stores various types of equipment inside.

Effect: As a result of the above, those who need to irradiate infrared rays intensively from their waist to shoulders, etc., can stand up and irradiate infrared rays directly to their lower limbs using an infrared radiation tube, without raising the air temperature in the sauna room too much. In addition to being able to obtain sufficient sweating effect,
By separating the space below the horizontal infrared radiation tube from the sauna room into a heat-insulating section and creating a machine room that houses various equipment necessary for combustion of gaseous fuel, such as fuel and air supply, exhaust, and control equipment, the overall size can be reduced. Can be summarized compactly.

Light mainly composed of infrared rays is generated from the outer surface of seat 2, and the infrared rays are mainly radiated in the direction of seat 1 by the action of reflector 17a and the like.

The combustion gas in the metal tube combustion chamber 22 gradually lowers its temperature while passing through the second metal tube 24 and the third metal tube 25.
In the order of

Unlike other infrared radiation tubes, the infrared radiation emitted from the outer surface of the lower part 26b of the fourth metal tube heats the lower part of the seat 1 and the drainboard 9.

The seat 1 in this example has a length that can accommodate three people.
A bather sits facing the infrared radiation device 10 through the burn prevention shelf 28 shown in FIG.

c is 90cm from the floor.

Therefore, the amount of infrared rays radiated in the direction of the seat 1 is greatest at a height between 50 cm and 90 cm above the floor surface.

However, in the portion facing the vertical fourth metal pipe, infrared rays are irradiated onto the seat 1 not only above but also below the drainboard surface.

Effects of the invention A gas-fired infrared radiation sauna heater that converts the combustion heat of gaseous fuel into infrared rays and irradiates the human body with the heat is already known from Japanese Patent Application Laid-open No. 59-21913 and Japanese Patent Application Laid-Open No. 59-21927.

Furthermore, there is Utility Application No. 59-162174, and the present invention aims to further improve the invention and obtain a gas-fired infrared radiation sauna heater that is more effective and effective for the human body without reducing the effects of the invention. It is.

The effects of the present invention will be explained below in comparison with the effects of Utility Model Application No. 162174/1982.

The present invention and Utility Model Application No. 59-162174 are intended to obtain various effects by devising the arrangement and combination of sauna interior components such as seats and infrared radiation.

The gist of the arrangement combination in Utility Model Application No. 59-162174 is to arrange a plurality of infrared emitting tubes horizontally in a position that almost faces the abdomen of the bather, and in a position closer to the bather than conventional gas-fired sauna devices. The space below the group of infrared radiation tubes, that is, the space facing the lower limbs of the bather, is used as a machine room for storing various equipment necessary for combustion of gaseous fuel, and is basically similar to the arrangement combination of the present invention. However, the difference is that in the present invention, a part of the space facing the lower limbs is used as an extension part for the infrared radiation tube, and the remaining space is used as a machine room.

Due to these differences, the following new effects were obtained in the present invention.

1 The infrared radiation tube extension can irradiate infrared rays to the lower limbs of the bather, so the lower limbs can be warmed more quickly, or for people with lower limb disabilities, the infrared radiation effect can warm the lower limbs. Since blood circulation is promoted, it can also be applied to rehabilitation, etc.

2 As the floor surface is heated by infrared rays, the air near the floor surface is heated and creates an upward flow, resulting in counterclockwise convection in Figure 4, which reduces the temperature difference between the top and bottom of the entire sauna room. , giving you a more comfortable bathing experience.

3. By adding more infrared radiation tubes, the heat transfer area increases, and since the added part is in the lower part of the sauna room where the temperature is lowest, the amount of heat transfer increases.

Both of these effects increase thermal efficiency and increase energy efficiency.

This will be explained in more detail below.

One of the features of Utility Model Application No. 59-162174 is that it shortens the distance between the infrared radiation device and the human body, and directs the infrared rays to the parts of the human body that require heating or are prone to perspiration, thereby making it possible to Enhances the infrared radiation effect from gas-fired sauna bath equipment,
It lowers the temperature of the sauna room compared to conventional saunas, making it more comfortable and more energy-saving, allowing even the elderly and children to take a bath with peace of mind.

After making a prototype of the invented device and conducting various experiments, it was found that even when the temperature of the sauna room was around 70°C, sufficient perspiration was obtained due to the infrared radiation effect.

40 for a conventional air convection sauna.
It has been proven that this sauna device has an energy saving effect of more than 30% compared to gas-fired infrared radiation devices that are already in practical use, and that even the elderly and children can safely take a bath.

However, problems arose in that the feet were cold or it took a long time for the toes to warm up.

Fig. 7 is a schematic diagram of the inside of the device of Utility Application No. 59-162174 as seen from the non-exit side, and the dotted arrow in the figure indicates the main direction of infrared rays irradiated. Infrared rays are not emitted.

As a result, even if the temperature in the upper part of the sauna room rose to about 70 degrees Celsius, the air temperature near the drainboard 9 only rose to an initial temperature of about 30 to 40 degrees Celsius.

Of course, if the temperature is over 30℃, you won't feel cold; you will warm up after a while after taking a bath, and you will even feel hot, so in general, this may not be a particularly serious disadvantage, but especially if it is cold When bathing with a cold body in the ground, many bathers want to warm up quickly.

If you think about the human body when it's cold, when the temperature is low, in order to reduce the amount of heat radiated from the human body, the human body constricts blood vessels and reduces the flow of blood, lowering the temperature of the skin and increasing the temperature with the outside air. I'm trying to keep the difference small.

When blood flow is reduced, the feet, which are farthest from the heart, are most affected.

Therefore, when you enter a sauna room with a cold body, it is natural that you want to warm up your feet as quickly as possible, since the temperature is lowest at your feet.

If the abdomen, chest, etc. are heated by infrared rays,
This heat is transmitted to the whole body by the blood, but it takes time for the heat to be transmitted by the blood to the feet, which are located farthest from the heart.

Infrared rays are directly radiated to the lower limbs of the person sitting on the seat facing the infrared radiation tube extension part 26b of the device of the present invention, so that the lower limbs can be heated more quickly.

In the non-infrared emitting tube extension section, the floor surface of the extension section is directly heated by infrared rays, so the air near the floor surface is warmed, and when the warmed air rises, the air near the machine room section 13 is heated to fill the void. The air moves, and after the air moves, the air at the top descends, resulting in counterclockwise air convection when viewed from the seat side, which also warms the air near the non-infrared emitting floor, reducing the temperature difference between the top and bottom of the sauna room. 162174
Your feet will be warmed up faster than the No. 1 device.

Next, to explain the effect of increasing thermal efficiency,
If more infrared radiation tubes are installed, the heat transfer area will increase, and naturally the amount of heat transfer will increase, leading to an increase in thermal efficiency.

In particular, the amount of heat transfer is proportional to the difference between the surface temperature of the infrared radiation tube and the air temperature near the surface in convection heat transfer, and is proportional to the fourth power of the absolute temperature of the surface of the infrared radiation tube in radiation heat transfer. Since it is proportional to the difference between the absolute temperature of the drainboard surface facing the infrared radiation tube and the air, etc. to the fourth power, the amount of heat transferred by the additional infrared radiation tube that exchanges heat with the floor near the lowest temperature in the sauna room is It has relatively more efficiency and energy saving effect than other infrared radiation tubes.

In particular, in the first embodiment shown in FIG. 4, the radiation tube 26b of the infrared radiation tube extension part is located at the most downstream part where the combustion gas temperature decreases the most, and the combustion gas with the lowest temperature and the floor with the lowest temperature in the sauna room. Since heat exchange occurs with the air near the surface, the amount of heat transfer increases.

As mentioned above, the present invention is an improvement on the device of Utility Model Application No. 162,174/1985, which heats the abdomen of the human body, which tends to sweat, so that it can warm the feet more quickly and improve thermal efficiency. The present invention is not limited to the embodiments described above, but can be modified in various ways.

For example, FIG. 8 is a front view of an infrared radiation device 10 according to a second embodiment, which corresponds to FIG. 4 of the first embodiment. The metal tube extension part of the radiation tube storage box 17, that is, the storage part for the vertical metal tube 26b, was used, but in the second embodiment, on the contrary, the lower right side was used as the compartment 13, and it rose up inside the infrared radiation tube storage box 17 on the left side. A metal tube is provided, and the rising metal tube is used as the metal tube combustion chamber 22. Since the surface temperature of the metal tube is higher than in the first embodiment, more infrared rays can be irradiated toward the lower limbs of the human body.

FIG. 9 is a front view of the infrared ray emitting device 10 of the third embodiment, in which a section 13 is provided at the lower center, a vertical metal tube 26 is provided on the right side as in the first embodiment, and a second section is provided on the left side.
This embodiment is provided with the raised metal tube combustion chamber 22 of the embodiment, and has the effects and features of the first embodiment and the second embodiment.

While the first and second embodiments are devices that can accommodate about three people, this embodiment is suitable for devices that can accommodate four to five or more people.

Air convection in this embodiment is directed toward the left metal combustion tube 2.
An upward air current is generated in the second part, and a downward air current is generated in the central part, so that the air rotates clockwise, and on the right side, the air rotates and flows counterclockwise.

FIG. 10 is a front view of the infrared radiation device 10 of the fourth embodiment.

In this embodiment, the infrared radiation tube storage box 17 of the embodiment device of Utility Application No. 59-162174 is installed at an angle, and all the metal tubes are inclined tubes, but the lower right side is heated. This embodiment has the same effect as each of the embodiments in that the lower limbs of the human body can be heated.
