(Embodiment 1)
As shown in FIG. 1, a device body 3 for forming a sauna device is provided in a ceiling space 2 of a sauna target room 1 made of a bathroom or the like. To the sauna target room 1. Further, a water supply pipe 6 that supplies water to the apparatus main body 3 and a drain pipe 7 that drains water discharged from the apparatus main body 3 are connected to the apparatus main body 3. The apparatus main body 3 includes the apparatus main body 3 in the ceiling back space 2 through the ceiling opening 5 of the sauna target room 1, has a panel 8 on the sauna target room 1 side, and sandwiches the ceiling 9 between the apparatus main body 3 and the panel 8. It is.

  The apparatus body 3 is surrounded by a box-shaped frame 10 having an opening toward the ceiling opening 5, and includes a water supply valve 11 and a water supply pipe 12 that form a water circuit therein, a tank 13 and a tank 13 that store the supplied water. A drain port pipe 14 and a drain valve 15 communicating with the inside of the tank 13 are provided at the lower part of the tank 13, and the tank 13 has one or a plurality of ultrasonic oscillators 17 at the bottom as the humidifying means 16, while The panel 8 is provided with a suction port 18 for sucking air and a blower port 19 for blowing air, and circulation circulation leading from the sauna target chamber 1 to the blowing means 20 through the joining portion 22 where humid air above the humidifying means 16 drifts from the suction opening 18. The air flow that has the passage 21 and is guided to the air blowing means 20 passes through the heater 23 that is the heating means and is blown into the sauna target room 1 from the air outlet 19.

  The apparatus body 3 includes a control unit 24 (not shown) electrically connected to a water supply valve 11, a drain valve 15, an ultrasonic oscillator 17, a blower unit 20, and a heater 23 which is a heating unit. Is configured to control the operation of the water supply valve 11, the drain valve 15, the ultrasonic oscillator 17, the air blowing means 20, and the heater 23 that is a heating means.

  Inside the tank 13 of the humidifying means 16 are provided a cooler 25 for cooling the water temperature, a water temperature detecting means 26 for detecting the water temperature, and a water level detecting means 27 for detecting the water level in the tank 13, and a control means 24 for instructing sauna operation. Is recognized, the water supply valve 11 is opened, and tap water is guided from the water supply pipe 6 through the water supply pipe 12 into the tank 13, and water is accumulated in the tank 13. When the water in the tank 13 exceeds a certain water level, the water level detection means 27 operates to send a signal to the electrically connected control means 24, and the control means 24 sends a “closed” signal to the water supply valve 11 to supply water. The valve 11 is closed and the water supply to the tank 13 is stopped. Further, a signal is sent from the control means 24 to the ultrasonic oscillator 17, the ultrasonic oscillator 17 is operated, and the humidifying means 16 is humidified. On the other hand, simultaneously with the operation of the ultrasonic oscillator 17, an operation signal is sent from the control means 24 to the blowing means 20, the blowing means 20 is activated, and the air that has flowed from the sauna target chamber 1 through the inlet 18 into the apparatus body 3 is It becomes humidified air and is blown from the air outlet 19 to the sauna target room 1.

  On the other hand, when the control means 24 recognizes the sauna operation instruction, an operation signal is transmitted to the heater 23 which is the heating means, and the heater 23 is heated and the blower 20 is operated. Since the air that has been passed passes through the humidifying means 16 and then passes through the heater 23, the heated humidified air is blown into the sauna target room 1.

  Since heated humidified air is blown from the blower outlet 19 to the sauna target chamber 1, the temperature and humidity in the sauna target chamber 1 increases with time. Since the air in the sauna target room 1 that has become hot and humid is heated and humidified again in the suction device body 3 from the suction port 18, the water temperature in the tank 13 of the humidifying means 16 located in the circulation passage 21 gradually increases. Will go. When the water temperature rises, especially when the temperature exceeds 60 ° C., the precipitation of minerals such as calcium, magnesium, silica, etc. dissolved in the water becomes remarkable and the scale ratio in the water increases, resulting in adhesion to the inner wall of the tank 13 or ultrasonic waves. It adheres to the surface of the oscillator 17. Further, when the water in the tank 13 is drained after the sauna operation is finished, the deposited scale may remain on the surface of the ultrasonic oscillator 17 or may adhere to the inner surface of the drain pipe 7 and cause drainage failure. For this reason, a water temperature detection means 26 is provided in the tank 13 to constantly detect the water temperature in the tank 13 and to detect a temperature above a certain temperature, for example, 30 ° C. or more, as a signal to the electrically connected control means 24. And a signal is sent from the control means 24 to the cooler 25 provided in the tank 13, and the operation of keeping the water temperature in the tank 13 at 20 to 30 ° C. is performed by the cooler 25. Since the life of the ultrasonic oscillator 17 is shortened when the water temperature in the tank 13 is high, managing the water temperature is effective for the maintenance frequency or the life of the humidifying means 16, that is, the apparatus main body 3. Further, when the humidifying means 16 is operated, the water level in the tank 13 for humidifying decreases. When the water level in the tank 13 falls below a certain value, the water level detection means 27 is activated, a signal is sent to the electrically connected control means 24, and a signal is sent from the control means 24 to the water supply valve 11. The valve 11 is opened and tap water is supplied from the water supply pipe 14 to the tank 13.

  When the control means 24 recognizes the sauna operation stop signal, the control means 24 sends a signal to the electrically connected blower means 20, the ultrasonic oscillator 17, and the heater 23 to stop. Further, when the cooler 25 and the water supply valve 11 are operating, the cooler 23 and the water supply valve 11 are also stopped or closed. After the water supply valve 11 is closed, the drain valve 15 is opened, and the residual water in the tank 13 is discharged from the drain pipe 7 to the outside of the apparatus body 3 through the drain port pipe 14. Therefore, it is possible to suppress the growth of various germs in the residual water when the sauna is stopped and the adhesion of the mineral component originally contained in the residual water in the residual water drying, that is, the scale component. The scale or dust adhering to the surface of the ultrasonic oscillator 17 leads to a reduction in the life or destruction of the ultrasonic oscillator 17, so that the apparatus main body 3 is concealed in the ceiling space 2 as in the embodiment of the present invention. In this case, the maintenance frequency can be reduced and the product life can be extended.

  In addition, the air in the sauna target room 1 sucked from the suction port 18 merges with the humidified air having an average particle diameter of 10 μm or less humidified by the ultrasonic oscillator 17 and the merging portion 22 located above the humidifying means 16, and enters the blades. The air is guided to a heater 23 as a heating means through a blowing means 20 having a sirocco fan 28. The humidified air is sucked into the sirocco fan 28 as the gas-liquid separation means 29, and is crushed into finer water particles by colliding with each blade of the sirocco fan 28. The humidified air that has passed through the sirocco fan 28 is It collides with the wall surface around the sirocco fan 28 that constitutes the circulation flow passage 21, and large water droplets adhere. The adhering large water droplets are collected by a self-weight in a large water droplet collection dish 30 provided at the lower part of the sirocco fan 28, and the large water droplet collection dish 30 is connected to the tank 13 of the humidifying means 16 in a water channel. Since the arrangement has a downward slope, the water collected in the large water droplet collection dish 30 is returned to the tank 13.

  On the other hand, the humidified air that has passed through the sirocco fan 28 becomes only fine water droplets having an average particle size of 1 μm or less, is heated through the heater 23, and is blown out into the sauna target room 1 through the outlet 19 as finely heated humidified air. The Rukoto. Humidity is diffusive, while fine water droplets intersect with the air current, so the heated humidified air blown into the sauna target room 1 has a uniform temperature and humidity, and a sauna apparatus that provides a uniform sauna target room 1 with no unevenness. Become.

  FIG. 2 shows the blown particle size distribution of the ultrasonic oscillator 17, and FIG. 3 shows the blown particle size distribution of the outlet 19. This test is performed with a phase Doppler laser particle analyzer. As can be seen from FIG. 2, the average particle diameter is 2 to 5 μm when the ultrasonic oscillator 17 is humidified. The average particle generated from the humidifying means 16 because the particle size varies depending on the frequency and the particle size peak value may actually be 0.75 μm or less because the particle size of 0.75 μm or less cannot be measured as a measuring device. The diameter was set to 10 μm or less. When the particle size is large, when heated by a heater after that, the latent heat of vaporization causes an unnecessarily reduced temperature of the air flow, while large water droplets are not heated and are only heated and blown out from the outlet 19. Immediately after being blown out into the space 1, it falls to the floor surface due to its own weight and is drained, so that the heating / humidification contribution of the sauna target room 1 is remarkably reduced. Further, it is desirable that the humidified air blown into the sauna target room 1 does not feel bodily or water-cooled. For this reason, the particle diameter is made fine at the time of the suction side of the heater 23, and the water droplets are heated by the heater 23 or heated by the heater 23. It is necessary to blow out humidified air having no water-cooling feeling to the sauna target room 1 by heating with the air flow heated by 23. Further, since the passing particle diameter is reduced through the gas-liquid separation means 29, the humidified air is blown out into the sauna target chamber 1 (FIG. 3), and the inside of the sauna target chamber 1 is effectively heated and humidified. It will be. In FIG. 3, the particle size peak is at 0.75 μm. However, as described above, since the particle size of 0.75 μm or less cannot be measured with the measuring instrument, the particle size peak is at a finer particle size. Can easily be expected.

  As a result, it is possible to provide the sauna target room 1 which is a space that does not give the user troublesomeness due to water droplets, so that reading in the sauna target room 1 is possible and the range of use of the sauna target room 1 is expanded. In addition, since hot water is not used, the life of the apparatus body 3 itself can be extended.

  In the embodiment of the present invention, the sirocco fan 28 of the blowing means 20 is used as the gas-liquid separating means 29. However, a separate gas-liquid separating means 29 may be provided between the humidifying means 16 and the blowing means 20, By providing the separating means 29 on the suction side of the air blowing means 20, the water droplets present in the humidified air guided to the air blowing means 20 are already in a fine state, so that large water droplets are formed on each blade of the sirocco fan 28. And the electric motor (not shown) that drives the sirocco fan 28 can prevent the deterioration due to the ingress of large water droplets, thereby improving the durability of the blowing means 20.

  Further, although the ultrasonic oscillator 17 is used as the humidifying means 16, the gas-liquid separating means 29 may be used on the leeward side of the high-pressure spray humidifying system or the centrifugal humidifying system. By changing the performance of the liquid separating means 29, the air blowing means 20, and the humidifying means 16, that is, the high pressure spray humidifying system or the centrifugal humidifying system, the same diameter can be obtained, so there is no difference in action and effect.

  The high-pressure spray humidification method refers to a method of pressurizing feed water and spraying water or water and compressed air from the injection port to humidify, and the centrifugal humidification method is by supplying water to a rotating disk that rotates at high speed. The water is a thin film on the disk and flows out from the edge of the disk, and the water that flows out sprays and humidifies when it collides with the eliminator around the disk. The ultrasonic humidification system is installed on the lower surface of the ultrasonic transducer surface. Then, a fountain-like water is formed on the surface of the water by ultrasonic vibration, and water is atomized and humidified from the formed underwater tip.

A second embodiment will be described. Note that the same parts as those in Embodiment 1 are denoted by the same symbols, and the description thereof is omitted.

  As shown in FIG. 4, the apparatus body 3 is surrounded by a box-shaped frame 10 having an opening toward the ceiling opening 5, and the panel 8 as an air circuit includes a suction port 18 for sucking air and a blower port 19 for blowing air, The first circulation flow passage 21a that passes through the suction port 18 from the sauna target chamber 1 and is blown to the merging portion 22 by the blowing means 20, and the humidification that is disposed on the leeward side by the blowing means 31 that passes through the suction port 18 and is humidified. It has the 2nd circulation flow path 21b which becomes humidified air via the means 16, and guides it to the confluence | merging part 22, passes the heater 23 which is a heating means from the confluence | merging part 22, becomes heating humidified air from the blower outlet 19 to a sauna object room 1 is blown out.

  According to the above configuration, since the air blowing means 20 and the air blowing means 31 for the humidifying means are arranged on the windward side from the humidifying means 16 or the merging portion 22, they can be directly exposed to high humidity or large droplets of humidified air from the humidifying means 16. Therefore, it is possible to suppress the deterioration with time due to the collision of the large water droplets with the blades, and it becomes easy to select the electric motor used for each blowing means.

  Moreover, since it has the 1st circulation flow path 21a which performs only ventilation, and the 2nd circulation flow path 21b which ventilates humidified air, it is a blower outlet by the combination of the operation / stop of the ventilation means 20 and the ventilation means 31 for humidification means. The relative humidity of the blown-out air blown out from 19 can be easily operated, and can meet the needs of a wide range of users from users who prefer high temperature and high humidity to users who prefer medium temperature and low humidity.

  In this embodiment, the gas-liquid separation means 29 is not provided. However, the large water droplets are separated from the humidification means 16 of the second circulation flow passage 21b on the leeward side, and the large water droplets are collected and the fine water drops are collected. A gas-liquid separation means 29 that allows only the water to pass therethrough may be provided, and since only fine water droplets are supplied to the merging portion 22, precipitation of scale contained in the water droplets on the surface of the heater 23 is reduced and the life of the heater 23 is ensured. There is an effect that it is easy to do.

(Embodiment 3)
A third embodiment will be described. The same parts as those in the first and second embodiments are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIGS. 5 and 6, the tank 13 of the humidifying means 16 is provided with a cooler 25 for cooling the water temperature, a water temperature detecting means 26 for detecting the water temperature, and a water level detecting means 27 for detecting the water level in the tank 13. When the control means 24 recognizes the sauna operation instruction, the water supply valve 11 is opened, and tap water passes through the water supply pipe 12 through the water supply pipe 6 and is introduced into the tank 13, and water is collected in the tank 13. It will be. When the water in the tank 13 exceeds a certain water level, the water level detection means 27 operates to send a signal to the electrically connected control means 24, and the control means 24 sends a “closed” signal to the water supply valve 11 to supply water. The valve 11 is closed and the water supply to the tank 13 is stopped. Further, a signal is sent from the control means 24 to the ultrasonic oscillator 17, the ultrasonic oscillator 17 is operated, and the humidifying means 16 is humidified. On the other hand, simultaneously with the operation of the ultrasonic oscillator 17, an operation signal is sent from the control means 24 to the blowing means 20, the blowing means 20 is activated, and the air that has flowed from the sauna target chamber 1 through the inlet 18 into the apparatus body 3 is It becomes humidified air and is blown from the air outlet 19 to the sauna target room 1. The ultrasonic oscillator 17 attached to the lower portion of the tank 13 may break down when it is idled in the absence of water, and the ultrasonic oscillator 17 generally attaches a ring-shaped packing material 17a to the tank 13. Since a method of sealing with a structure that touches the bottom surface is common, the oscillator itself of the ultrasonic oscillator 17 is positioned at the lowermost part of the tank 13. On the other hand, the tank 13 is provided with a rotation support means 32 and a rotation drive means 33 at both end faces, and the rotation support means 32 is a rod-like one located at the center of the end face of the tank 13, while the opposite end face is provided at the center position. A rod-like rotation support means 32 and a rotation drive means 33 for rotating the rod of the rotation support means 32 are provided. The rotation driving means 33 is electrically connected to the control means 24.

  When the control means 24 recognizes the sauna operation stop signal, the control means 24 sends a signal to the electrically connected blower means 20, the ultrasonic oscillator 17, and the heater 23 to stop. When the cooler 25 and the water supply valve 11 are operating, the cooler 25 and the water supply valve 11 are also stopped or closed. The heater 23, the ultrasonic oscillator 17, the cooler 25, the water temperature detection means 26, and the water level detection means 27 are connected to the control means 24 so as to be extendable or slack. After the water supply valve 11 is closed, the control means 24 sends a signal to the rotation drive means 33 to drive the rotation drive means 33, and the tank 13 rotates around the rotation support means 32 positioned facing the tank 13. The tank 13 is rotated 180 ° from the initial position, so that all the remaining water in the tank 13 is dropped to the lower part. A pan 34 is provided at a position below the tank 13 at a sufficient distance for the tank 13 to rotate 180 °. The pan 34 has a box shape with an upper surface opened, and has a hole communicating with the drain pipe 14 on the bottom surface. The capacity depends on the rotation speed of the rotation driving means 33. In other words, if the rotation speed of the rotation drive means 33 is high, a capacity almost equal to that of the tank 13 is required, while the rotation speed of the rotation drive means 33 is slow and the amount of water falling from the tank 13 and the bottom of the pan 34 are provided. If the amount drained from the hole to the drain pipe 14 is equal, the capacity of the pan 34 can be reduced. Further, the rotation drive means 33 starts driving and a signal is transmitted from the control means 24 to the drain valve 15, and the drain valve 15 opens and the residual water recovered from the pan 34 by dropping from the tank 13 is provided at the bottom of the pan 34. By passing through the hole and discharging it from the drain pipe 7 to the outside of the apparatus main body 3 through the drain port pipe 14, no residual water remains in the tank 3 and the pan 34, and in particular, the tank 13 is upside down. Due to the fall of the residual water, the residual water of the oscillator itself located at the lower part of the packing material 17a is completely eliminated, and the minerals originally contained in the residual water in the residual water in the residual water proliferation and the residual water drying when the sauna is stopped. In other words, adhesion of scale components can be suppressed. The scale or dust adhering to the surface of the ultrasonic oscillator 17 leads to a reduction in the life or destruction of the ultrasonic oscillator 17, so that the apparatus main body 3 is concealed in the ceiling space 2 as in the embodiment of the present invention. In this case, the maintenance frequency can be reduced and the product life can be extended. The rotation drive means 33 is driven in a direction opposite to the direction of rotation again after a certain time after the rotation drive means 33 has rotated 180 °, and stops when the tank returns to the original position. Thereafter, the air blowing means 20 is operated, and the air flow flows on the surface of the tank 13 so that the inner surface of the tank 13 is completely dried.

(Embodiment 4)
A fourth embodiment will be described. The same parts as those in the first to third embodiments are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 7, the apparatus main body 3 is surrounded by a box-shaped frame 10 having an opening toward the ceiling opening 5, and the panel 8 as an air circuit has a suction port 18 for sucking air and a first blower port 19a for blowing air. A first circulation flow passage 21a that passes from the sauna target chamber 1 through the suction port 18 and is blown to the merging portion 22 by the blowing means 20, and a second circulation through the suction port 18 and the humidification means 16 It has a flow passage 21b. The second circulation flow passage 21b is provided with an air passage switching damper 36 for switching between the air passage leading to the joining portion 22 of the first circulation flow passage 21a and the air passage leading to the second outlet 19b on the leeward side of the humidifying means 16. I have. When the air path switching damper 36 is switched to the merging portion 22 side of the first circulation flow passage 21a, the air flowing through the second circulation flow passage 21b is humidified by the humidifying means 16, and then the sauna target room 1 in the merging portion 22. The air that has been sucked from the air is combined into air containing only fine water droplets by the gas-liquid separation means 29, and then passes through the heater 23 to become heated humidified air containing only fine water droplets from the first air outlet 19a. It is blown out to the sauna target room 1. On the other hand, when the air path switching damper 36 is switched so that an air flow flows through the second circulation flow passage 21, the air flow passing through the second circulation flow passage 21b is not guided to the merging portion 22 but from the outlet 19b. It is divided into an air passage that blows out into the chamber 1 and an air passage that heats the air sucked from the sauna target chamber 1 by the heater 23 and blows out from the air outlet 19a. For this reason, the air flow passing through the second circulation flow passage 21 b is blown out from the second air outlet 19 b while being humidified by the humidifying means 16, and the humidifying means 16 is ultrasonically applied to the lower part of the tank 13. The air humidified from the humidifying means 16 includes a fine one to visible water droplets at a soot level because of the system provided with the oscillator 17, and the humidified air blown out from the second outlet 19b is visually observed. It will contain dripping water droplets that can be made.

  In the above configuration, by switching the air path switching damper 36, it is possible to switch from the blowout port 19 to a mode in which heated humidified air containing only fine water droplets and humidified air containing visually visible soot-level water droplets are blown out. The mode can be selected according to the user's needs. In addition, it is difficult for the user to know that the humidified air that contains only fine water droplets is humidified unless the instrument is used. Because it is difficult for people who plan to use the equipment before purchasing the equipment to experience a sauna bath with fine water droplets, moisturizing and humidifying can be used for advertisements that appeal only to the visual sense, such as flyers. A very large effect can be expected.

  In the embodiment of the present invention, when the soot is generated, the heated air is blown from the first circulating flow passage 21a to the sauna target chamber 1, but a new damper is provided in the first circulating flow passage 21a. In the mode for generating the air, it may be configured so that air does not flow through the first circulation flow passage 21a. In the case of the above-described configuration, the air flow is blown out only from the second outlet 19b without passing through the heater 23. There is an effect that water droplets are not evaporated by heating, and more soot can be blown out into the sauna target chamber 1.

An attached oscillator fixing means 37 is provided. A water level detection means 27 for detecting the water level in the tank 13 is provided inside the tank 13, and the water level detection means 27 is a position where the surface of the ultrasonic oscillator 17 provided in the oscillator fixing means 37 is completely immersed in water. It is provided at a position where a signal is transmitted to the control means 24.

Become. When the water in the tank 13 exceeds a certain water level, the water level detection means 27 operates to send a signal to the electrically connected control means 24, and the control means 24 sends a “closed” signal to the water supply valve 11 to supply water. The valve 11 is closed and the water supply to the tank 13 is stopped. Further, a signal is sent from the control means 24 to the ultrasonic oscillator 17 so that the ultrasonic oscillator 17 operates. The wave generated from the ultrasonic oscillator 17 is reflected by the reflecting plate 38 provided on the bottom surface of the tank 13, and the water surface stored in the tank 13 is vibrated and humidified.

  When the control means 24 recognizes the sauna operation stop signal, it sends a signal to the electrically connected ultrasonic oscillator 17 and stops. Further, when the water supply valve 11 is operating, the water supply valve 11 is also stopped or closed. After the water supply valve 11 is closed, the drain valve 15 is opened, and the residual water in the tank 13 is discharged from the drain pipe 7 to the outside of the apparatus body 3 through the drain port pipe 14. In particular, since the scale or dust adhering to the surface of the ultrasonic oscillator 17 leads to a reduction in the life or destruction of the ultrasonic oscillator 17, the apparatus main body 3 is placed in the ceiling space 2 as in the embodiment of the present invention. In the case of installation that conceals light, maintenance frequency can be reduced and product life can be extended.

The angle of the ultrasonic oscillator 17 is a sufficient angle for removing air lumps remaining when water is supplied to the surface of the ultrasonic oscillator 17. Further, a water level detection means 27 for detecting the water level in the tank 13 is provided inside the tank 13, and the water level detection means 27 is a position where the surface of the ultrasonic oscillator 17 provided in the oscillator fixing means 37 is completely immersed in water. At a position to transmit a signal to the control means 24. When the control means 24 recognizes the sauna operation instruction, the water supply valve 11 is opened, and tap water is guided from the water supply pipe 6 through the water supply pipe 12 into the tank 13, and water is accumulated in the tank 13. Become. As the water in the tank 13 accumulates, the ultrasonic oscillator 17 provided in the oscillator fixing means 37 is immersed. However, since the ultrasonic oscillator 17 is attached obliquely, the surface of the ultrasonic oscillator 17, that is, Since the air dam that has lost the place of accumulation on the bottom surface side of the tank 13 of the oscillator fixing means 37 is directed toward the water surface of the water stored in the tank 13, the ultrasonic oscillator 17 is completely immersed in water. In addition, no air lumps remain on the surface of the ultrasonic oscillator 17. Thereafter, when the water level exceeds a certain level, the water level detecting means 27 operates to send a signal to the electrically connected control means 24, and the control means 24 sends a “closed” signal to the water supply valve 11 so that the water supply valve 11 is closed and the tank is closed.
