  Thus, since the mist sauna apparatus of the said patent document 1 needs to drain the mist cut by the filter, the drain pipe connected to the external drainage equipment etc. is needed. In other words, the conventional mist sauna apparatus requires installation of the apparatus and further piping of this drain pipe, which is troublesome.

  Moreover, the mist sauna apparatus of the said patent document 1 had room for improvement also from a viewpoint of using water efficiently. In other words, the water cut by the filter in the generated mist is simply drained, and cannot be said to be used effectively.

  This invention is made | formed in view of the said situation, The place made into the objective makes the drain piping for draining the mist which does not pass a filter unnecessary, and utilizes the mist which does not pass a filter for a mist sauna bath. An object of the present invention is to provide a mist sauna device.

When the mist is discharged from the mist discharge port 36, most of the mist arrives at the filter 7 along the air circulated by the blower fan 80. Of the mist that has arrived at the filter 7, the mist having a size smaller than a predetermined size passes through the filter 7. On the other hand, mist of a predetermined size or larger is restricted by the filter 7 but is evaporated by being heated by the second heating means 4. Further, even if a part of the mist discharged from the mist discharge port 36 that has not arrived at the filter 7 is generated, the mist is heated and evaporated by the second heating means 4. These evaporated mists are discharged from the mist discharge port 12 together with the air in the circulating passage 2 that circulates. Thereby, the mist sauna apparatus of this invention becomes unnecessary [the drain pipe for draining the mist which does not pass filter 7]. Further, since the mist that does not pass through the filter 7 is evaporated and this water vapor is used for humidifying the mist sauna space, the mist that does not pass through the filter 7 can be used without draining.
Further, since both the first heating means 3 and the second heating means 4 are heat exchangers, the mist sauna device of the present invention has a simpler configuration.

Further, even if a part of the mist discharged from the mist discharge port 36 that has not arrived at the filter 7 is generated, the mist is also introduced to the second heating means 4 by the water introduction means 29. These waters guided to the second heating means 4 are evaporated by the warm air heated by passing through the first heating means 3 and the second heating means 4. The water vapor is discharged from the mist outlet 12 together with the air flowing through the lower passage 22 heated by the second heating means 4 and the fine mist that has passed through the filter 7. Thereby, an effective mist sauna bath can be performed.

  The first passage 27 is the upper passage 21, the second passage 28 is the lower passage 22 adjacent to the lower portion of the upper passage 21, and the water guiding means 29 is provided on the lower side surface 26 of the upper passage 21. It is preferable that the communication path 24 communicates the upper path 21 and the lower path 22.

  If comprised in this way, the water conveyance from the upper channel | path 21 of the mist which does not pass the filter 7 to the lower channel | path 22 can be performed using gravity.

  Moreover, it is preferable that the water guiding means 29 further includes an opening / closing means 290 that enables water passing or stopping of the mist that does not pass through the filter 7.

  Accordingly, if the second heating unit 4 is not operating or has not reached a predetermined temperature at the start of operation, water flow to the second heating unit 4 can be stopped. Thereby, it can reduce that the water guide | induced to the 2nd heating means 4 retains in the 2nd channel | path 28 without evaporating.

A micro mist generating nozzle 35 is connected to the side. Further, a drain electromagnetic valve 43 is connected to the downstream side of the branch portion of the micro mist generating nozzle 35.

  The heat exchanger for mist 42 uses a heat medium circulating from the heat source unit 90 as a heat source. The mist heat exchanger 42 is connected to a mist heating hot water pipe 44 as shown in FIG. The mist heating hot water pipe 44 is provided with a water proportional valve 45 upstream of the mist heat exchanger 42, and a hot water return sensor 46 is provided along the pipe downstream of the mist heat exchanger 42. Further, the heat exchanger 40 of the second heating means 4 is provided on the downstream side thereof. The water proportional valve 45 is supplied to the mist heat exchanger 42 from the mist heating hot water pipe 44 based on the temperature detected by the mist temperature sensor 49 that detects the temperature of the mist (splash mist and fine mist). The supply amount of the heat medium is adjusted, and a heat medium having a flow rate necessary for obtaining a set temperature is supplied to the heat exchanger for mist 42.

It falls to the upper end part of the exchanger 40 (specifically, near the upper edge of the metal fin 401 located on the upper side of the heat exchanger 40). The mist cut by the filter 7 flows down on the surface of the filter 7 and then collects in the water collecting section 25. Then, the mist (water) stored in the water collecting section 25 falls through the communication path 24 and falls to the upper end portion of the heat exchanger 40 of the second heating means 4. The water dropped on the upper end portion of the heat exchanger 40 flows down along the inclined fin 401 and finally evaporates while flowing down. In the present embodiment, the communication passage 24 constitutes a water introduction means 29 that guides the mist that has not passed through the filter 7 from the upper passage 21 to the second heating means 4.

  On the downstream side of the filter 7 in the circulation passage 2, the upper passage 21 and the lower passage 22 join as described above, and the joined circulation passage 2 communicates with the outlet 16.

The splash mist generating nozzle 50 has a splash mist spray port 51 at the front end, and as shown in FIG. 2, the rear end is connected to a splash mist conduit 47 branched from the mist water supply pipe 38. ing. The splash mist conduit 47 is provided with a nozzle opening / closing valve 48. The splash mist pipe 47 is provided with the mist temperature sensor 49 described above for detecting the temperature of hot water flowing through the pipe 47.

  The bathroom heater / dryer A with a mist sauna function of the present embodiment is provided with a ventilation fan 81 inside the apparatus main body 1. As shown in FIGS. 1 and 3, the ventilation fan 81 is provided in a ventilation path 82 that connects the air suction port 11 and a ventilation port 83 that faces the outside, and the air in the ventilation path 82 is converted into air. The air is circulated from the suction port 11 toward the ventilation port 83.

  In the bathroom heating / drying machine A with a mist sauna function of the present embodiment, various operation controls are performed by the control unit. This control unit is constituted by a microcomputer and receives signals from the remote control operation unit 91 and detection signals from the bathroom temperature sensor 33, the hot water going-out temperature sensor 34, the mist temperature sensor 49, and the hot water return sensor 46. Based on each detection signal, each valve is opened and closed and the blower fan 80 and the ventilation fan 81 are driven. For example, the control unit controls the blower fan 80 based on the bathroom temperature sensor 33 to keep the temperature in the bathroom at a predetermined temperature, or to open the drain electromagnetic valve 43 for a certain time at the start of the mist operation. The residual water having a low temperature accumulated in the heat exchanger 42 for water and the water supply pipe 38 for mist is discharged to the outside.

  The bathroom heater / dryer A with the mist sauna function configured as described above operates as follows.

  When performing a mist sauna with a fine mist having a particle size smaller than that of the splash mist, the micro mist sauna operation switch of the remote control operation unit 91 is pressed. Then, a signal instructing the start of the micro mist sauna is sent from the remote control operation unit 91 to the control unit. The control unit sends a command to the heat source unit 90, and the heat source unit 90 that has received the command starts operating. At the same time, the control unit opens the thermal valve 32 and the water proportional valve 45. When the thermal valve 32 is opened, a high-temperature heat medium (hot water of about 80 ° C.) sent from the heat source device 90 starts to circulate through the heating hot water conduit 31, and when the water proportional valve 45 is opened, this high-temperature heat The medium begins to circulate through the mist heating hot water pipe 44. When the warm water going temperature sensor 34 detects a predetermined temperature (for example, 60 ° C.) or higher, the control unit drives the blower fan 80 and simultaneously opens the outlet 16. Then, the air in the bathroom is taken into the apparatus main body 1 through the air inlet 11, and hot air is blown out from the outlet 16. Thereafter, when the bathroom temperature sensor detects a predetermined temperature (for example, 25 ° C.) or higher, the control unit opens the micro mist electromagnetic valve 37 to release the mist from the micro mist generating nozzle 35. Most of the mist arrives at the filter 7 along the air flowing through the circulation passage 2, and only the mist having a predetermined particle diameter passes through the filter 7 and the air flowing through the lower passage 22 downstream thereof. It merges and is discharged from the outlet 16.

  At this time, the mist whose passage is restricted by the filter 7 flows downward along the filter 7 and falls to the water collecting portion 25 provided on the partition plate 23. Even if a part of the mist discharged from the mist discharge port 36 that has not arrived at the filter 7 is generated, the mist falls into the water collecting section 25. These fallen mists move into the lower passage 22 through the communication passage 24 provided in the water collecting portion 25 and fall to the upper end portion of the heat exchanger 40 of the second heating means 4. The water droplets falling on the upper end of the heat exchanger 40 flow down along the inclined metal fin 401 and finally evaporate while flowing down. The evaporated mist (water) is blown into the bathroom together with air flowing through the lower passage 22 as steam.

  Next, in order to end the operation of the micro mist sauna from this state, the operation stop switch of the remote control operation unit 91 is pressed. Then, the control unit closes the micromist electromagnetic valve 37 and the water supply electromagnetic valve 41. At this time, the control unit maintains the state in which the thermal valve 32 is opened, and maintains the state in which the blower fan 80 is driven. Then, after a predetermined time (5 minutes in the present embodiment) has elapsed since the electromagnetic valve 37 for micromist is closed, the thermal valve 32 is closed and the blower fan 80 is stopped.

  Thus, since the 2nd heating means 4 which evaporates the mist which does not pass the filter 7 is provided in the bathroom heating dryer A with a mist sauna function of this embodiment, in order to drain the mist which does not pass the filter 7. No drain pipe is required. Further, since the mist (water droplets) not passing through the filter 7 is evaporated and the water vapor is used for humidifying the mist sauna space, the mist not passing through the filter 7 can be used without draining.

  In addition, since the first heating means 3, the second heating means 4, and the blower fan 80 are operated for a predetermined time from the time when the supply of mist is stopped, the second heating means 4 and the Even if water droplets remain in the circulation passage 2, the water droplets can be evaporated and dried. Thereby, generation | occurrence | production of mold | fungi in the circulation channel | path 2 or the 2nd heating means 4 can be prevented.

  In addition, the bathroom heater / dryer A with a mist sauna function of the present embodiment is provided so that the heat exchanger 40 of the second heating means 4 covers the lower passage 22 and is inclined, so that the lower passage 22 is provided. While effectively heating the circulating air, the water that does not pass through the filter 7 passing through the surface can slowly flow down and reliably evaporate.

  Further, since the water guiding means 29 is constituted by the communication path 24, the mist that does not pass through the filter 7 can be guided to the second heating means 4 by using gravity. This provides a more compact configuration. Further, since the water introduction means 29 is provided with the opening / closing means 290, if the heat exchanger 40 of the second heating means 4 is not operating or has not reached a predetermined temperature, etc. The water introduction to the second heating means 4 can be stopped. Thereby, it can reduce that the water guide | induced to the 2nd heating means 4 does not evaporate, but stays in the 2nd channel | path 28, and generation | occurrence | production of mold | fungi etc. can be prevented.

  Next, when performing the mist sauna by the splash mist, the splash mist sauna operation switch of the remote control operation unit 91 is pushed. Then, the same control as the above-described operation is performed, and warm air blows out from the outlet 16 to raise the temperature in the bathroom. When the bathroom temperature sensor detects 25 ° C. or more, the control unit opens the nozzle opening / closing valve 48 to release the splash mist from the splash mist nozzle 50.

  When performing the heating operation, the heating operation switch of the remote control operation unit 91 is pressed. Then, the control unit opens the thermal valve 32 and the water proportional valve 45. Thereafter, when the warm water going-out temperature sensor 34 detects 60 ° C. or more, the control unit drives the blower fan 80 and simultaneously opens the blowout port 16 and blows warm air from the blowout port 16. And after raising the temperature of a bathroom to predetermined | prescribed temperature, based on the detection signal of the bathroom temperature sensor 33, rotation of the ventilation fan 80 is controlled and the inside of a bathroom is kept at a constant temperature.

  When performing the ventilation operation, the ventilation operation switch of the remote control operation unit 91 is pressed. Then, the control unit drives the ventilation fan 81 to discharge the air in the bathroom to the outside.

  When performing the drying operation, the drying operation switch of the remote control operation unit 91 is pressed. Then, the control unit opens the thermal valve 32 and the water proportional valve 45 and drives the blower fan 80 and the ventilation fan 81. Thereafter, the rotation of the blower fan 80 is controlled based on the bathroom temperature sensor 33, and drive control is performed so that the room temperature becomes a predetermined set value.

  As described above, in the present embodiment, the heat exchanger 40 of the second heating unit 4 is arranged in series on the downstream side of the heat exchanger 42 for mist, and the heat for mist that has been exhausted in the past has been used. Since the amount of heat from the exchanger 42 is used, energy can be used with high efficiency.

  According to such a configuration, the heat exchangers 30, 40, and 42 can be accurately controlled. For example, the operation of only the heat exchanger that is not used is stopped, or the flow rate of the heat medium for each heat exchanger. The amount of heat to be supplied can be adjusted, and the amount of heat supplied can be adjusted, so that efficient operation control can be performed.

  As mentioned above, although the mist sauna apparatus of this invention was demonstrated based on the bathroom heating dryer A with a mist sauna function, the mist sauna apparatus of this invention should just have the function of a mist sauna, and is an operation | movement only of heating.
