Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a steam sauna that creates a high humidity environment within a sauna booth.

[Prior Art] A conventional steam sauna of this type is shown in FIG. 9. That is, in the conventional steam sauna 91, the exhaust passage 3 is formed in the upper part of the sauna booth 92, and the steam supply pipe 94 is opened and arranged in the lower part. The steam supply pipe 94 is
Steam generated by heating the water stored in the water tank 95 with a heater 96 and boiling it is supplied to the room 97 . On the other hand, fresh air is forcibly blown through a fan 99 to an air supply pipe 98 disposed within the steam supply pipe 94 and is discharged near the outlet side of the steam supply pipe 94 . Then, by mixing the steam and fresh air and spouting it into the indoor room 99 of the sauna booth 92, the temperature of the steam is lowered and
This creates an atmosphere of appropriate temperature and high humidity. The reason for supplying fresh air is that if only the steam generated by boiling the stored water is spouted into the room 97, the room temperature 97 will become high and there is a risk of getting burned. The air-fuel mixture injected into the chamber 97 sequentially rises to the upper part of the chamber and is discharged from the exhaust passage 93 to the outside. During use, the air-fuel mixture is continuously ejected into the interior 97.

[Problem to be solved by the invention] As described above, in the conventional steam sauna 91, steam generated by boiling and fresh air are mixed and supplied, and this is exhausted from the exhaust passage 93. However, the heat capacity of the exhausted air-fuel mixture was lost, making it impossible to effectively utilize the heat capacity.
That is, there were disadvantages in that heat loss was large and the total amount of steam used increased. In addition, since the water stored in the water tank 95 is boiled (heated to 100°C) to generate steam, a large-capacity heater 96 of 3200 W or more is usually required just to boil the stored water. This has caused an increase in the size and cost of the device.

Also, since the inside of the sauna booth is hot and humid,
If you use it for a long time, you may feel palpitations or dizziness.

[Means for Solving the Problems] The steam sauna of the present invention includes a sauna booth provided with a seat inside; the sauna is placed outside the sauna booth, and one end side is opened in a part of the sauna booth. and an air flow path whose other end side is open in another part of the sauna booth; an air flow path provided in the air flow path that directs air from the one end side to the other end side of the air flow path; a blower device for the air to flow; an electric heater provided in the air flow path for heating the air flowing in the air flow path; a container for storing water and a container provided in the container for generating steam; a steam generating means installed in the air flow path so that the generated steam is mixed with the air flowing through the air flow path; A side wall of the sauna booth is provided with an opening for blowing air outside the sauna booth toward the upper body region of the person sitting on the seat above the seat. .

[Operation] In the steam sauna of the present invention, the ultrasonic oscillator is operated to vibrate the water stored in the water tank and generate mist-like water vapor. This atomized water vapor is ejected into the room as a mixed fluid of steam and hot air and circulated. Temperature of circulating fluid with steam, normal case
The temperature is 38-45℃. Since this is a circulating steam sauna, the heat capacity of the circulating fluid does not directly escape to the outside, allowing for effective heat utilization.

In addition, since the air outside the sauna booth (hereinafter sometimes referred to as fresh air) is blown toward the sauna user, dizziness and palpitations can be prevented, allowing the sauna user to continue using the sauna in an exhilarating manner. On this occasion,
By selecting the position and direction of the blow-off opening so that fresh air blows out only towards the user's desired face and neck area, it is possible to maintain the overall hot and humid atmosphere inside the sauna booth while providing a comfortable environment for the user. It can give you a refreshing feeling.

Reference numerals 42 and 43 indicate an upper can body and a lower can body, and the flange portions 42a of these can bodies 42 and 43,
43a are overlapped and connected by bolts (not shown) to form a container 37A, in which water W is stored.

The upper can body 42 has an air inlet 44 and an air outlet 45 to which the duct 41 is connected, and is provided with a heater (sheathed heater in this embodiment) 46 as a heating means. Lower can body 43
A water supply pipe 47 is connected to the solenoid valve 48 via a solenoid valve 48, and a drain pipe 49 is connected to the solenoid valve 50 as a drainage means.
connected via.

The lower can body 43 is provided with an ultrasonic oscillator 52, a water temperature sensor 53, a float switch 54, and an overflow pipe 55.

Reference numeral 56 denotes a partition plate, which is provided substantially horizontally so as to partition the interior of the container 37A made up of the can bodies 42 and 43 into upper and lower sections. This partition plate 56
The air introduced from 4 is directly blown onto the water surface of the water W to prevent the water surface from rippling. That is, if the surface of the water W ripples excessively, the atomization effect of the water W by the ultrasonic oscillator 52 may be inhibited, and the amount of steam generated may decrease. Therefore, in this embodiment, the partition plate 56 is configured to prevent the airflow from the inlet 44 from being blown directly onto the water surface. The partition plate 56 is provided with an opening 57 above the ultrasonic oscillator 52, and is configured to facilitate the flow of atomized water vapor toward the channel opening 45.

The partition plate 56 is configured to surround the lower portion of the heater 46 so that the radiant heat of the heater 46 is not absorbed by the water W. With this configuration, the radiant heat radiated downward from the heater 46 is absorbed or reflected by the partition plate 56,
It is used to heat the air flowing above the partition plate 56, improving heating efficiency.

A side plate 58 and a ceiling plate 59 are provided on the sides and above the heater 46 , and a gap is interposed between the side plate 58 and the ceiling plate 59 and the upper case body 42 . These side plates 58 and ceiling plate 59 also function to prevent the radiant heat from being transmitted from the upper can body 42 to the outside by absorbing or reflecting the radiant heat from the heater 46, thereby improving heating efficiency. Further, if the partition plate 56 and the side plate 58 are provided as in this embodiment, the water vapor atomized from the water W passes through the opening 57 and is mixed with the circulating air flow in the zone downstream from the heater 46. . Therefore, water vapor does not come into direct contact with the heater 46, and water scale is prevented from adhering to the surface of the heater 46. As a result, the heat dissipation characteristics of the heater 46 are high over a long period of time. In addition, ceiling board 5
9 is fixed to the ceiling surface of the can body 42 with bolts (not shown), and the side plate 58 and the partition plate 56 are attached to the ceiling plate 5.
It is suspended at 9.

Reference numeral 60 indicates a can temperature sensor attached to the upper can body. Further, reference numeral 61 indicates a heater terminal.

As shown in FIGS. 4 and 6, a flexible duct 62 is connected to the outlet 45 of the upper can body 42, and the duct 62 is connected to the outlet 19 provided in the inner panel 14 of the booth 2. Therefore, in this embodiment, the ducts 39, 41, 62 and the steam generator 37 constitute a flow path for circulating the air in the booth interior 11.

As shown in FIG. 3, the inner panel 14 is provided with a fresh air outlet (hereinafter sometimes referred to as "fresh air") 63 for introducing fresh air from outside the booth 2 into the booth interior 11. There is. The fresh air port 63 is provided at approximately the height of the head, neck, or chest of the user seated on the seat portion 8. The fresh air port 63 is provided with a vent member 63a so that the blowing direction can be changed freely. It is set up. As shown in FIG. 4, the fresh air port 63 can communicate with the outside of the booth via a duct 64 and a damper device 65. Further, as shown in FIG. 1, the exhaust fan 26 also communicates with the outside of the booth via a duct 66, a damper device 67, and a duct 68.

When the exhaust fan 26 is operated with the damper devices 65 and 67 open, the air is exhausted from the booth interior 11, and fresh air is introduced into the booth interior 11 from the fresh air port 63, causing the seat section 8 to be seated. Since fresh air is blown toward the face of the user, the user is prevented from getting hot while using the sauna, and can enjoy a refreshing sauna experience.

At this time, the fresh air is a local wind blown out only from the fresh air port 63, and the overall high temperature and humidity atmosphere in the booth interior 11 is maintained as it is. In order to maintain a hot and humid atmosphere below the neck, it is preferable that the fresh air port 63 be provided at a height slightly below the neck so that the fresh air is blown diagonally upward. be.

In this embodiment, fresh air can be reliably blown around the user's face and neck by manually adjusting the direction of the vent member 63a according to the user's height and posture.

Note that when the exhaust fan 26 is operated to suck fresh air into the booth interior 11 as in this embodiment, no humid air leaks from the booth interior 11 to the outside. For this reason, booth 2
This prevents dew condensation from occurring near the area. Incidentally, when fresh air is forced into the booth interior 11 by a fan, there is a risk that humid air will leak outside the booth, causing dew condensation and making the surrounding area humid. When configured as in this embodiment, the area near the installation location of the sauna booth can be maintained in a good environment.

Further, in this embodiment, the damper device 65,
67, it is possible to reliably prevent outside air from flowing into the booth interior 11 when unnecessary.

An electric circuit box 70 is installed below the waterproof pan 4 as shown in FIG.
A circuit for controlling electrical equipment of the steam sauna such as a blower 36, an ultrasonic oscillator 52, and a heater 46 based on signals from the box 62 is built into the box 62. A panel 71 is detachably attached to the side surface of the waterproof pan 4.

In the steam sauna configured in this way, a user opens the door 30 to enter and exit. According to the normal usage method, before entering the booth room 11, the heating/humidifying switch provided on the external operation panel 32 is pressed. As a result, the blower 36, heater 46, and ultrasonic oscillator 52 are activated, and the booth interior 11 becomes warm and sufficiently humid. After this, I went inside the booth to warm up and take a shower.

In the booth room 11, the user operates the blower 36 by operating the switch on the indoor operation panel 27.
The rotation of the airflow outlet 19 can be controlled to adjust the flow rate of the airflow blown out from the air outlet 19. Further, by operating a switch on the operation panel 27, the output of the air heating heater 46 can be controlled to adjust the temperature of the blown air stream, and the output of the ultrasonic oscillator 52 can be controlled to adjust the air stream temperature. Similarly, the output of the far-infrared heater 28 can be adjusted and the exhaust fan 26 can be turned on and off. Note that output adjustment also includes turning off the device.
In this steam sauna, while staying in the booth room 11, the temperature and humidity inside the booth can be controlled by the far infrared heater 2.
8 operations, allowing booth users to create the most comfortable environment.

During this use, fresh air is blown out from the fresh air port 63 as described above, making it possible to use the sauna in a refreshing manner.

In the embodiment shown, the fresh air opening 63
Although only one is provided, a plurality of may be provided. In this case, the saunas may be installed at different heights, and fresh air may be blown out from fresh air ports at an appropriate height depending on the height of the sauna user. Further, the electric circuit box 70 may be installed on the upper surface of the ceiling of the booth 2. In this way,
Since the upper surface of the ceiling has good ventilation, heat radiation from the electric circuit box 70 can be promoted.

Note that the far-infrared heater 28 allows a sufficiently comfortable steam sauna to be used even without the use of the far-infrared heater 28. Furthermore, by operating the blower 36 and heater 46 without operating the ultrasonic oscillator 52,
It can also be used as a hot air sauna.

[Effects] According to the present invention, steam to make the room humid can be obtained using an ultrasonic device, and there is no need to heat the stored water to 100° C. and boil it as in the conventional method.
Therefore, the heating source only needs to be of a small capacity to heat indoor air to an appropriate temperature, and it is possible to significantly reduce the thermal energy used compared to the conventional case. In addition, the circulating fluid, which is a mixture of steam and hot air, repeatedly circulates in a closed flow path, so the thermal energy of the circulating fluid does not directly escape to the outside as in the past, which improves thermal efficiency. Are better.

Furthermore, with the steam sauna of the present invention, fresh air can be applied to the face, neck, etc. while using the sauna, making it extremely refreshing to use the sauna.
