The nozzle 20 jets the hot water J into the duct 11 at high speed in the form of a mist. As shown in FIGS. 3 and 4, a plurality of nozzles 20 are provided on the hot water header 21 in the longitudinal direction of the duct 11. Are mounted side by side. As shown in FIG. 5 (a), the empty conical nozzle 22 jets hot water J as a radial mist flow J1 substantially along a conical surface, and is well known. This empty conical nozzle 22 also has a mist flow J1 inside the conical surface as shown in FIG.
Has the advantage that the particle size of the mist can be made smaller than that of the charged conical nozzle 23, but has the disadvantage that the contact time of the mist flow J1 with the air K is shorter than that of the charged conical nozzle 23. have. In addition, the particle size of the mist generally decreases as the amount of hot water J injected from one nozzle decreases.

Therefore, the nozzle 20 uses the empty conical nozzle 22 and reduces the injection amount of the hot water J from one empty conical nozzle 22 by using a plurality of the empty conical nozzles. By making the mist particle diameter of the injected hot water J sufficiently small, and simultaneously injecting the hot water J from a plurality of hollow cone nozzles 22 arranged side by side,
The shape of the mist flow J1 can be approximated to the shape of the mist flow J1 of the charged conical nozzle 23, and the contact time between the mist flow J1 and the air K can be kept relatively long.

Here, the reason why the air can be sucked into the duct 11 by the mist flow J1 of the hot water J jetted from the nozzle 20 at high speed is the same as that by the ejector. Kinetic energy is applied to the air, and the air moves through the duct 11 to generate a negative pressure around the suction portion 11b of the duct 11. In this case, if the particle size of the mist is small, the contact area between the mist flow J1 and the air K increases,
The energy of the mist flow J1 is sufficiently transmitted to the air K side, and more air K can be sucked into the duct 11. In addition, mist flow J1 and air K
If the contact time with the mist flow J is long, the energy of the mist flow J1 is sufficiently transmitted to the air K side, so that much air K can be sucked into the duct 11.

If the particle size of the mist is reduced and the contact area between the mist flow J1 and the air K is increased, the amount of heat transfer from the mist to the air K is increased, and the air K is heated accordingly. When the contact time between the mist flow J1 and the air K becomes longer, the amount of heat transfer from the mist to the air K also increases.

Next, the operation of the sauna device 7 will be described. When the electromagnetic valve 32c of the hot water supply facility 30 is opened and the pressurizing pump 32a is operated, hot water J of a predetermined temperature and a predetermined pressure passes through the hot water supply pipe 31 and the air heater 40,
High-speed mist is injected into the duct 11 from the nozzle 20. Since the mist flow J1 of the hot water J moves the air in the duct 11 to the discharge unit 11c side, a negative pressure is generated on the suction unit 11b side of the duct 11, and the air is sucked into the duct 11 from around the suction unit 11b. . For this reason, the mist of the hot water J mixes with the air sucked into the duct 11 and flows through the duct 11 while giving heat to the air. Through the bathroom space W.

That is, the air K in the bathroom space W is sucked into the duct 11 and mixed with the mist of the hot water J to become the heated air L, and then is jetted out again into the bathroom space W. Heat inside. Then, the injection amount of the hot water J from the nozzle 20 is controlled, and the temperature in the bathroom space W is controlled to be, for example, 40 ° C., so that the sauna user in the bathroom space W gets warm. At the same time, the sweating action is promoted.

In this case, of the heated air L descending in the duct 11, the mist having a large particle diameter moves to the liquid reservoir 11d side and is removed, and the remaining mist from which the mist having the large particle diameter is removed ( The heated air L) is repelled by the staying air in the staying space R above the liquid reservoir 11d of the duct 11,
The direction of the flow is changed by about 90 degrees toward the discharge section 11c. Then, the heated air L is blown out of the discharge section 11c through the outlet horizontal guide plate 13 and the outlet vertical guide plate 14 in a desired direction of the bathroom space W. Further, the air K in the bathroom space W is sucked into the duct 11 from a desired vertical direction by the inlet guide plate 12.

Here, the air K is heated when it comes into contact with the mist, and the saturated vapor pressure rises. Then, the heated air L contains water vapor by an amount corresponding to the saturated vapor pressure of the air due to evaporation of the mist. In this case, the latent heat of vaporization of the mist is obtained by, for example, lowering the temperature of the other mist. Then, the heated air L injected into the bathroom space W mixes with the air K in the bathroom space W to produce new air K whose temperature has increased.
However, as shown in FIG. 7, since the saturated vapor pressure of the heated air L is significantly higher than that of the air K or the new air K ′, when the new air K ′ is formed, Then, dew condensation of water vapor occurs, and the new air K 'is sufficiently heated by the latent heat of evaporation of the water generated at this time. That is, the temperature of the new air K ′ is further increased by the amount of latent heat of evaporation of the condensed water from the temperature of the air obtained by simply mixing the heated air L and the air K.

On the other hand, the mist sprayed from the nozzle 20 mixes with the air in the duct 11.
1 is attached to and removed from the inner wall of
Large particles passing through the center of the
It adheres to and is removed. Therefore, of the mist ejected from the nozzle 20, most of the mist having a large particle diameter is stored in the duct 11, and the small mist is ejected into the bathroom space W as the heated air L. . The mist adhering to the inner surface of the duct 11 flows down along the inner surface of the duct 11 and is collected in the liquid reservoir 11 d of the duct 11.

The recovered hot water M in the liquid reservoir 11d is transferred to the bathtub 2 by operating the recovery pump 52a and can be used for bathing. Is a coupler with check valve 54b
After connecting a hose or the like, the reuse pump 54a is operated, so that it can be variously used as water for a washing machine, bathroom cleaning, and garden watering. The recovered hot water M
Also, the water may be discharged into the bathroom drain pit via the three-way valve 52c, or may be discharged from the bathtub 2 to the drain pit.

The heated air L flowing in the duct 11 is heated by the air heater 40 in the duct 11, but the temperature of the hot water J is reduced accordingly. The -40 seems to play no role for the sauna device 7. However, this air
Since the heater 40 decreases the temperature of the hot water J supplied to the nozzle 20, the temperature of the recovered hot water M discharged to the outside also decreases by that amount, so that the temperature of the bathroom space W is increased. Accordingly, the thermal efficiency of the sauna device 7 can be increased.

Since the air K and the mist flow J1 are parallel flows flowing in the same direction, the amount of heat transferred from the mist to the air K gradually decreases. However, since the flow of the hot water J in the air heater 40 and the flow of the heated air L in the duct 11 are opposed to each other, the heated air L flows toward and away from each other. The heat is efficiently heated by the air heater 40, and the thermal efficiency of the sauna device 7 can be increased accordingly.

As described above, in the sauna device 7, the air K is sucked into the duct 11 by utilizing the negative pressure generated by the high-speed injection of hot water in the form of a mist into the duct 11. Since the heated air L is formed by mixing K and mist, a large fan is not required for heating the air, which reduces the size and cost of the device, and reduces the operating and maintenance costs. Can be planned.

In the sauna device 7, the duct 11
Is installed vertically along the wall surface of the bathroom, and the nozzle 20 is arranged downward on the upper side of the duct 11 to inject the hot water J from above to below, so that the acceleration of gravity is also applied. The high-speed mist flow J1 is obtained, and the negative pressure of the suction portion 11b of the duct 11 can be sufficiently increased accordingly. In this case, since the mist adhering to the inner surface of the duct portion 11 becomes a liquid film and flows downward, the suction portion 1 of the duct 11 is also caused by the flowing down of the liquid film mist.
1b, the heating and humidification of the air K can be performed, and the flow resistance of the heated air L to the duct 11 can be reduced by the flow of the liquid film mist. .

Further, in the sauna device 7, the mist of the hot water J is jetted in the duct 11, the mist having a large particle diameter is adhered to the inner surface of the duct 11, and is removed. Since the mist in the heated air L is removed by attaching to the liquid reservoir 11d by changing the flow direction by approximately 90 degrees, the ratio of the mist having a large particle diameter in the heated air L jetted into the bathroom space W Can be reduced. For this reason, the inconvenience that the mist having a large particle diameter touches the body of the sauna user and gives an unpleasant feeling can be sufficiently solved.

Further, in the sauna device 7, since the vertically long duct 11 from the vicinity of the ceiling panel 9 to the counter 5 is used, heating and humidification of the air J by the mist of the hot water J are sufficiently performed. Mist duct 11
By the adhesion to the inner surface, the mist of the warm water J having a large particle diameter is sufficiently removed.

Further, in this sauna device 7, the liquid reservoir 1
A stagnant space R is formed between the upper surface of the collected hot water M of 1d and the lower end of the discharge portion 11c, and the heated air L in the duct 11 repels the stagnant air in the stagnant space R, so that the bathroom space W The heated air L is prevented from strongly colliding with the recovered hot water M in the liquid reservoir 11d, and is recovered after the heated air L collides with the recovered hot water M in the liquid reservoir 11d. It is possible to prevent the hot water M from being spouted into the bathroom space W with a part of the hot water M.

In the sauna device 7, the duct 11
A liquid reservoir 11d is provided therein, and mist adhering to the inner surface of the duct 11 (the inner surface of the duct 11 or the liquid reservoir 11d) flows into the liquid reservoir 11d, so that it does not contribute to the heating of the air K. The recovered hot water J can be sufficiently recovered, and resources can be effectively used. In this case, since the splash water prevention filter 16 is provided on the liquid reservoir 11d, even if the heated air L collides with the liquid reservoir 11d,
The collected hot water M in the liquid reservoir 11d is not scattered, and no collision noise is generated.

Further, in the sauna apparatus 7, since the recovery pump 52a is provided to transfer the recovered hot water M in the liquid reservoir 11d to the bathtub 2 side, the recovered hot water M can be immediately used as hot water for bathing. And recovered hot water M
Is stored in the bathtub 2 to facilitate the use of the recovered hot water M. In particular, this sauna device 7
In the embodiment, since the recovered hot water M in the bathtub 2 can be transferred to another place by providing the reuse pump 54a, the use of the recovered hot water M can be further facilitated.

In the sauna device 7, the nozzle 20
However, since a plurality of empty conical nozzles 22 are provided side by side in the longitudinal direction of the duct 11, the particle size of the mist can be reduced, and the mist flow J1
Can be brought into contact with the air K for a relatively long time. Therefore, a large negative pressure is generated in the suction portion 11b of the duct 11, so that a sufficient amount of air K can be sucked into the duct 11, and the sucked air K can be sufficiently heated.

Further, in this sauna device 7, the duct 1
Since the air heater 40 is provided near the first discharge portion 11c to lower the temperature of the hot water J supplied to the nozzle 20, the temperature of the recovered hot water M discharged to the outside can be lowered, Accordingly, the thermal efficiency of the sauna device 7 can be improved, and the heated air L is heated by the heated water J by causing the heated water J and the heated air L to flow in opposite directions by the air heater 40. So that
As compared with the case of the parallel flow, the thermal efficiency of the sauna device 7 can be increased accordingly.

In the sauna device 7, the duct 11
A plurality of horizontal and vertical guide plates 14 and 15

Further, since a plurality of entrance guide plates 12 are provided in the suction portion 11b of the duct 11, the direction of the air K sucked into the duct 11 can be changed in the vertical direction.

Further, in the sauna device 7, since the nozzle 20 serving as a sound oscillating source is housed in the duct 11, noise in the bathroom space W can be suppressed and the outer surface of the duct 11 can be controlled. Because the vibration material is attached,
Accordingly, noise in the bathroom space W can be suppressed.

In the sauna device 7, the duct 11

As described above, in the sauna apparatus 7 as well, the air K is sucked into the duct 70 by utilizing the negative pressure generated by high-speed injection of hot water in a mist state in the duct 70, Since the heated air L is formed by mixing K and mist, a large fan is not required for heating the air, which reduces the size and cost of the device, and reduces the operating and maintenance costs. Can be planned.

In the sauna device 7, the duct 70
Is installed vertically along the wall surface of the bathroom, and the nozzle 20 is arranged downward in the duct 70 to inject the hot water J downward from above, so that the acceleration of gravity is also applied. The mist flow J1 is obtained, and accordingly, the negative pressure of the suction part 70a of the duct 70 can be sufficiently increased. In this case, since the mist adhering to the inner surface of the duct 70 flows down in the form of a liquid film, the negative pressure of the suction portion 70a of the duct 70 can be increased by the flow of the liquid film-like mist. The heating and humidification of the air K can be performed, and the flow resistance of the heated air L to the duct 70 can be reduced by the flow of the liquid film mist.

Further, in this sauna device 7, the duct 7
In addition to providing the suction portion 70a at the upper end of the nozzle 0 and installing the nozzle 20 in the vicinity of the suction portion 70a so as to inject the hot water J from above to below, the heating and humidification of the air K is substantially ducted. 70, the duct 70 and the like can be effectively used, and the air K

Further, in the sauna device 7, the mist of the hot water J is injected into the main duct 71, and the mist having a large particle diameter is attached to the inner surface of the main duct 71 to be removed.
By changing the flow direction of the heated air L by the separator 73,
Since the mist in the heated air L is removed by adhering to the liquid reservoir 70b, the ratio of the mist having a large particle diameter in the heated air L jetted into the bathroom space W can be reduced. For this reason, the inconvenience that the mist having a large particle diameter touches the body of the sauna user and gives an unpleasant feeling can be sufficiently solved. Note that the mist of the hot water J may also hit the upper wall
However, since the hot water flow path F communicating with the liquid reservoir 70b is formed on the outer surface side of the separator 73, the mist adhering to the upper wall 73b flows to the opening H2 side. As a result, it does not move to the ejection section 70c side.
