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, an exhaust passage 9 is formed in the upper part of a sauna booth 92, and a 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.

[Problems to be solved by the invention] While using a steam sauna, the user's body is placed in a high-temperature atmosphere, which may cause physical problems such as dizziness and palpitations. In conventional steam saunas, users had to go out of the sauna booth by themselves even in the event of this abnormality.

In addition, as mentioned above, the conventional steam sauna 91
In this case, the steam generated by boiling and fresh air are mixed and supplied, and this is exhausted from the exhaust passage 93, so that the heat capacity of the exhausted mixture is lost and sufficient heat capacity is effectively utilized. I couldn't figure it out. That is, there were disadvantages in that heat loss was large and the total amount of steam used increased.
In addition, the water stored in the water tank 95 is boiled (100
℃) to generate steam, a large-capacity heater 96 of 3200W or more is required just to boil the stored water, which increases the size and cost of the device.

[Means for Solving the Problems] The steam sauna according to claim 1 of the present invention includes a sauna booth; the steam sauna is arranged outside the sauna booth, one end thereof is opened in a part of the sauna booth, and the other end is opened in a part of the sauna booth; an air flow path whose side is open in another part of the sauna booth; and an air blower provided in the air flow path to flow air from the one end side to the other end side of the air flow path; a device; 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 an electric heater provided in the container for generating steam. a steam sauna equipped with a sonic oscillator and installed in the air flow path so that the generated steam is mixed with the air flowing through the air flow path; A switch for generating an emergency alarm signal is provided in the booth, and a control means is provided for stopping the blower and the air heater when the switch is operated.

The steam sauna according to claim 2 is the steam sauna according to claim 1, wherein the electric heater is provided in the container and above the ultrasonic oscillator, and the control means is configured such that when the switch is operated, the electric heater is provided above the ultrasonic oscillator. At times, the electric heater is stopped and the ultrasonic oscillator is operated for a predetermined period of time in order to cool the electric heater.

[Operation] In the steam sauna of the present invention, an ultrasonic oscillator is operated to vibrate the water stored in the container and generate a mist of water vapor. This atomized water vapor is ejected into the room as a mixed fluid of steam and hot air and circulated. The temperature of the circulating fluid with steam is usually between 38 and 45°C. 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 the steam sauna according to claim (1), a switch for generating an emergency alarm signal is provided in the sauna booth, and a control means is provided for stopping the blower and the electric heater when the switch is operated. Therefore, when a user who is using the sauna in the sauna booth becomes aware of physical abnormalities such as palpitations or dizziness, by operating this switch, the blowing of hot air will be stopped and the user will also be able to call for family members etc. An emergency alarm signal is generated for this purpose.

In the steam sauna of claim (2), the ultrasonic oscillator is operated even after the electric heater and the blower are stopped, and a mist of water vapor is generated. The electric heater is cooled by contacting the atomized water vapor with the electric heater. As a result, overheating of the electric heater and its surroundings is prevented.

This operation panel 32 includes main switches for electrical equipment in the sauna booth, switches for heating and humidifying, and lights 33 on the ceiling.
A switch for ON and OFF is provided.

A ceiling panel 35 is provided above the frame 13, and a lighting 33 for illuminating the booth interior 11 and a fan 26 for exhausting air from the booth interior 11 are installed. Further, a blower 36 is provided at the top of the booth 2 as a ventilation means. A steam generator 37 is installed below the seat portion 8 of the waterproof pan 4, as shown in an enlarged view in FIG. Blower 3
6 is connected to the inner panel 1 through the duct 39.
The discharge port 40 of the blower 36 is connected to the steam generator 37 via a flexible duct 41.

The structure of the steam generator 37 will now be described with reference to FIGS. 7 and 8.

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 container 37A consisting of the can bodies 42 and 43 into upper and lower parts. This partition plate 56 is connected to the inlet 44
The air introduced from the tank is directly blown onto the surface of the water W, thereby preventing the water surface from undulating. That is,
If the water surface of the water W ripples excessively, the atomization effect of the water W by the ultrasonic oscillator 52 is inhibited, and there is a risk that the amount of steam generated may decrease, or the float switch 54 may not be able to accurately detect the water surface. . Therefore, in this embodiment, the partition plate 56 allows
It is configured so that the airflow from the inlet 44 is not blown directly onto the water surface. The partition plate 56 is provided with an opening 57 above the ultrasonic oscillator 52 so that atomized water vapor can easily flow toward the discharge port 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 can body 42 . These side plates 58 and ceiling plate 59 also absorb or reflect the radiant heat from the heater 46, thereby preventing the radiant heat from being transferred from the upper can body 42 to the outside, 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,
This prevents water scale 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. The ceiling plate 59 is fixed to the ceiling surface of the can body 42 with bolts (not shown), and the side plates 58 and the partition plate 56 are suspended from the ceiling plate 59.

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 port 63 for introducing fresh air from outside the booth 2 into the booth interior 11. A vent member 63a is provided in the fresh air port 63 so that the blowing direction can be changed freely.
In this embodiment, a is provided toward the vicinity of the face of the user sitting on the seat portion 8. As shown in FIG. 4, the fresh air port 63 is connected to a duct 64 and a damper device 65.
It is possible to communicate with the outside of the booth via. 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 sauna user, it is possible to prevent hot flushes while using the sauna.

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.

A switch 72 is provided within the booth 2, and the output of this switch 72 is also input to the electric circuit box 70. Electric circuit box 7
A signal line is wired between 0 and a buzzer 73 attached to the outer peripheral surface of the booth 2. Note that the switch 72 is provided at a relatively low position so that the user can reach it even when crouching down. Further, the buzzer 73 is provided at the front of the booth 2 so that its sound can be propagated well.

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 33 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.

When a sauna user feels physical abnormality such as dizziness or palpitations in the booth 2, he or she presses a switch 72. This activates the buzzer 73,
Family members and others can rush to sauna booth 1 and rescue the person.

Further, when the switch 72 is pressed, the blower 36 and the heater 46 are stopped, and the blowing of hot and humid air into the booth room 11 is stopped. In this case, if the exhaust fan 26 has been stopped, the exhaust fan 26 starts operating, and fresh air is introduced into the booth interior 11.

Further, when the switch 72 is pressed, the ultrasonic oscillator 52 is operated for a predetermined period of time. As a result, the generated mist water vapor comes into contact with the heater 46,
The heater 46 and its surrounding area are cooled,
Overheating of the component is prevented. In this case, the blower 36
Since the water vapor is stopped, the mist of water vapor generated from the water W fills the container 37A and comes into contact with the heater 46. Note that since this switch 42 is operated very infrequently, even if water vapor comes into contact with the heater 46 in this way, water scale hardly dries up or adheres to the surface of the heater 46.

In the above description, a buzzer is used to generate the emergency signal, but various sound generating means such as a bell can be used. Further, an emergency light signal generating means such as an alarm lamp may be used, and a light signal and a sound signal may be generated simultaneously. Of course, the configuration may be such that an emergency signal is transmitted to an external security company or a manager's office.

In the present invention, the door 30 may be provided with an actuator for opening and closing, so that the door 30 is forcibly opened when the switch 72 is pressed. Also, the electrical circuit box 70 is located in booth 2.
It may be installed on the top of the ceiling. In this way, the upper surface of the ceiling has good ventilation, so that heat dissipation 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] As described above, in the steam sauna of the present invention, when the user becomes aware of a physical abnormality, he or she can notify the outside of the abnormality by operating the switch. Further, at this time, the blowing of hot and humid air into the booth room is stopped, so the user can be protected.

In the steam sauna of claim (2), it is possible to prevent the electric heater and its surroundings from overheating during the above-mentioned emergency stop.

Furthermore, according to the present invention, the 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 past. 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.
