A signal is sent to the circulation means 13 and the blower means 10, the water supply opening / closing means 18 performs an operation of stopping the water supply operation, and the drainage opening / closing means 21 performs an operation of opening the drainage closing valve 23 which is a drainage mode, while the hot water circulation means 13 and the blowing means 10 are stopped.

  FIG. 3 is an explanatory diagram schematically illustrating the configuration of the humidifying unit 9 in the sauna device according to Embodiment 1 of the present invention. As shown in FIG. 3, the humidifying unit 9 has a moisture permeable membrane 26 having water vapor permeability interposed therebetween, and a hot water path 27 for circulating hot water on one side of the membrane and an air channel 28 for circulating air on the opposite side are formed. It has been configured.

  The basic operation of the sauna device of the present embodiment having the above-described configuration is as follows.

  Hot water in the water circulation circuit 11 is circulated in the humidification unit 9 by the pump 14, and heat is exchanged with the hot water in the humidification primary hot water circuit 4 in the heat exchanger 12 to be heated to a predetermined temperature. The temperature at this time is about 70 ° C. when the temperature of the hot water in the humidifying primary hot water circuit 4 is about 80 ° C. The warm water inside the water circulation circuit 11 thus heated is supplied to the humidifying unit 9 and passes through the warm water path 27. At this time, only the water vapor passes through the moisture permeable membrane 26 having water vapor permeability and diffuses to the opposite side across the moisture permeable membrane 26, that is, the air path 28 side. The remaining warm water passes through the humidifying unit 9 and circulates in the water circulation circuit 11 as it is. On the other hand, the intake air is supplied to the humidifying unit 9 by the blowing means 10 and passes through the air flow path 28. At this time, the air is humidified by the water vapor transmitted from the hot water passage 27 and heated by heat exchange with the hot water. Then, the heated and humidified air is blown out into a bathroom or a shower room as a heated humidified space. Thus, the air in the bathroom or shower room is heated and humidified, and the indoor temperature and humidity conditions suitable for the sauna bath, that is, the temperature is maintained at about 40 to 50 ° C. and the relative humidity is maintained at about 70% or more.

  In the sauna apparatus of the present embodiment, only steam from the hot water circulating in the water circulation circuit 11 in the humidifying unit 9 is supplied to the air through the moisture permeable membrane 26, and the remaining hot water circulates again in the water circulation circuit 11 to form a heat exchanger. After being heated at 12, it is supplied to the humidifier 9 again. For this reason, the energy which the remaining warm water holds can be reused effectively, and efficient humidification is possible. As a result, the amount of hot water used and the amount of heating for raising the temperature of the hot water to a predetermined temperature are reduced, and the running cost can be suppressed.

  Moreover, it is the structure which supplies only the water vapor | steam which permeate | transmitted the moisture-permeable film 26 to air instead of ejecting warm water in the air. For this reason, fine water droplets are not blown into the bathroom and do not touch the bather's body, which makes the body feel comfortable.

  The humidifying means 1 is electrically connected to the operation remote controller 6, and is instructed to operate by the operation remote controller 6, so that water is supplied from the water supply circuit 16 to the water storage unit 14 and is circulated in the water circulation circuit 11 by the pump 13. Become. The number of bacteria in the city water immediately after the water is supplied is below the standard stipulated in the Water Supply Law, but with the passage of time, the chlorine component in the circulating water will jump and the bacteria will easily propagate. The humidifying means 1 includes a water residence time control means and a sterilization mode as bacteria generation suppression means. The water residence time control means, which is one of the bacteria generation suppression means, will be described below.

  When the water supply opening / closing means 18 of the water supply circuit 16 is opened, the water storage section 14 is supplied with water and the electrically connected control circuit 24 is notified that the water supply opening / closing means 18 is opened. When the water level supplied to the water storage unit 14 reaches the position of the water level sensor 17, the water supply opening / closing means 18 is closed and the water supply is ended. The supplied water is circulated when the hot water circulation means 13 is operated inside the water circulation circuit 11 including the water reservoir 14 as a part. During operation, a part of the water becomes steam from the humidifying unit 9 and is released into the bathroom 101, so that the water level in the water storage unit 14 gradually decreases, but the warm water circulating means 13 is the lowest position where air does not bleed ( When it comes to (not shown), the water supply opening / closing means 18 is opened again to supply water to the water storage section 14. On the other hand, when the sauna operation is stopped, that is, when the hot water circulating means 13 and the air blowing means 10 stop operating, the circulating water stays in the water circulation circuit 11. Since the water storage part 14 has a partly open part (not shown), airborne bacteria enter the residual water remaining in the water circulation circuit 11 through the water storage part 14 from the open part. On the other hand, the control circuit 24 is electrically connected as water retention time control means after a certain time after the water supply opening / closing means 18 is opened, that is, before the residual chlorine concentration in the water suitable for breeding within 24 hours becomes low. An open signal is sent to the drain stop valve, and when the signal is received, the drain stop valve 23 is opened, and the residual water in the water circulation circuit 11 is discharged outside the apparatus through the drain circuit 22 which is the drain opening / closing means 21. For this reason, propagation of underwater bacteria is suppressed, and the humidifier 9 serves as a sauna device in which the discharge of bacteria is suppressed.

FIG. 4 shows an internal structure diagram of heating means and humidifying means of the sauna apparatus in the second embodiment of the present invention. Note that the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the sauna apparatus is stopped, that is, when the humidifying means 1 and the heating means 2 are stopped, the delayed drainage means 30 starts to accumulate the stop time as water residence time control. The delay drainage means 30 sends an open signal to the drainage shutoff valve 23 electrically connected to the delay drainage means 30 after a predetermined time has elapsed, and the drainage shutoff valve 23 opens in response to the signal to remove residual water in the water circulation circuit 11. It drains out of the apparatus through a drain circuit 22 which is a drain opening / closing means 21.

  After a certain period of time, the chlorine in the water is within the time to suppress the growth of bacteria in the water, and although it depends on the water temperature, generally, if it is within 24 hours at room temperature, the bacteria will propagate due to residual chlorine in the tap water. Because it is suppressed, it is within 24 hours at the longest. On the other hand, the hot water stored in the water storage section 14 is high temperature of 60 to 70 ° C., so the drain pipe constructed on the drain opening / closing means 21 is not heat resistant. Because of problems such as cracks in the drainage pipe, it is necessary to leave the hot water stored in the water storage unit 14 for about 3 to 10 minutes after it has been kept at about 50 ° C. or less for a certain period of time. Within 24 hours after water supply from the time until the water temperature drops.

  A water temperature detection unit 29 is provided in the water circulation circuit 11, and the water temperature detection unit 29 detects the water temperature in the water circulation circuit 11. The water temperature detection unit 29 is electrically connected to the control circuit 24 as water residence time control means, and after the sauna device is stopped, that is, after the humidification means 1 and the heating means 2 are stopped, the temperature of the water in the water circulation circuit 11 is below a certain temperature, For example, when the water temperature detection unit 29 detects that the temperature is 45 degrees or less, the control circuit 24 sends an open signal to the drainage shutoff valve 23, and the drainage shutoff valve 23 is opened in response to the signal to remove residual water in the water circulation circuit 11. It drains out of the apparatus through a drain circuit 22 which is a drain opening / closing means 21. As a result, the drainage can be drained at an early timing after the sauna is shut down, and the residual water can be drained before the aquatic bacteria breed. The drainage water temperature is not high, so even a general-purpose drainpipe can be drained sufficiently. There are no restrictions on sex. Also, even if water leaks out from the drainage route, it will not cause burns.
