  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The mist sauna apparatus 25 of this example is installed in the ceiling part of the bathroom 10, as shown in FIG. A heat source device 6 with a hot water supply function is installed outside the bathroom 10, a wireless bathroom remote controller 19 is installed on the wall inside the bathroom 10, and a dressing room remote controller 35 is installed on the wall of the dressing room.

  The bathroom remote control 19 includes, for example, each display of operation mode, temperature, air volume, wind direction, and bathing time, a mist sauna switch for instructing the start of mist sauna operation, a mist strength switch for switching mist strength, and a target set temperature A temperature setting switch for setting (for example, 38 ° C. to 46 ° C.), a heating switch, a cool air switch, a wind direction switch, a stop switch, a start / stop switch for counting the bathing time, a reset switch, and the like are provided. The dressing room remote controller 35 is also provided with a similar operation unit. Thus, the operation before bathing can be performed with the dressing room remote controller 35 and the operation during bathing can be adjusted with the bathroom remote controller 19.

  As shown in FIG. 1, the mist sauna device 25 includes a heater body 1 that supplies hot air N into the bathroom 10, a mist spray unit 2 that sprays hot water as mist M, the heater body 1, and the mist. The control part 4 (FIG. 10) which controls the spraying unit 2 is provided. In this example, it is separated into a heater main body box 1a for housing the heater main body 1 and a mist unit box 3, which are coupled to each other with the mist unit box 3 mounted on the heater main body box 1a.

  In the heating dryer box 1a, there are a circulation fan 22, an air conditioner heat exchanger 33 for heating the air ventilated by the circulation fan 22 to the circulation ventilation path 5, and a bathroom thermistor 16 constituting a bathroom temperature sensor. Is arranged. In this example, in order to increase the heat exchange efficiency of the heat exchanger 33 for air conditioning, the vertical heat exchange section 33a and the horizontal heat exchange section 33b are divided and arranged adjacent to each other, and the forward path 7a of the hot water circulation path 7 is provided. The heat exchange units 33 a and 33 b are connected to the entrance sides of the two heat exchange units 33 a and 33 b, respectively, and the heat exchange units 33 a and 33 b are connected to the return sides 7 b of the two hot water circulation paths 7. The forward path 7 a of the hot water circulation path 7 is connected to a hot water supply side joint 20 on the hot water discharge side of the heat source machine 6, and the return path 7 b of the hot water circulation path 7 is connected to a recovery side hot water return side joint 21. Has been.

  Here, in the forward path 7a of the warm water circulation path 7, a thermal valve 8 for opening and closing the warm water circulation path 7 and a warm water thermistor 9 for detecting the warm water temperature are arranged. The hot water temperature detected by the hot water thermistor 9 is the temperature of the hot water that heats the heat exchanger 33 for air conditioning and the liquid heat exchanger 11 described later, and the ON operation of the circulation fan 22 is performed as described later according to this temperature. The mist solenoid valve 15 is opened and closed. Here, the circulation fan 22 is composed of, for example, a cross flow fan that rotates around a horizontal axis and performs both suction and exhaust of air along a direction orthogonal to the rotation axis, and is substantially in the direction of the rotation axis. The air in the bathroom 10 is sucked through the air conditioning heat exchanger 33 over a wide range over the entire width, and the air heated in the air conditioning heat exchanger 33 is ventilated so as to blow out from the hot air outlet 32 to the bathroom 10. It is configured. The ventilation fan 31 rotates around the vertical axis, for example, sucks air from the lower side of the fan case, and passes through the exhaust duct 38 (FIG. 2) through the discharge port formed on the side surface of the heater body box 1a. ).

  On the other hand, the mist spraying unit 2 supplies the water supply solenoid valve 17 that opens and closes the water supply path 12 connected to the water pipe 36 (FIG. 2) via the water supply joint 26 and the water supplied from the water supply path 12 from the heat source unit 6. A liquid-to-heat exchanger 11 for heating with hot water, and a plurality of (for example, two) mist nozzles 13 (13a, 13b) for spraying water heated by the liquid-to-heat exchanger 11 in a mist form, A pair of mist solenoid valves 15 for individually opening and closing each mist nozzle 13 and a mist temperature thermistor 30 for detecting the mist spray temperature are provided. In the example of FIG. 1, the liquid heat exchanger 11 is disposed in the mist unit box 3, and the mist nozzle 13 and the mist electromagnetic valve 15 are disposed in the heater main body box 1a. The mist ejection amount of the mist nozzles 13a and 13b is, for example, 0.5 liter / min, and is designed to eject both in strong operation and in one operation in weak operation.

  Here, the liquid heat exchanger 11 is composed of, for example, a plate heat exchanger in which a plurality of corrugated plate-like heat transfer plates are stacked at intervals. The primary side water channel of the liquid heat exchanger 11 communicates with the water supply channel 12, and the secondary side water channel communicates with the hot water branch circuit 23. An upstream of the hot water branch circuit 23 is connected to the forward path 7a of the hot water circuit 7 on the front side of the thermal valve 8 via a water proportional valve 14 that allows the supply amount of hot water to be changed and adjusted. The other end of the branch circulation path 23 is connected to the return path 7 b of the hot water circulation path 7.

  Further, one end of a drainage channel 24 is connected between the liquid heat exchanger 11 in the water supply channel 12 and the mist solenoid valve 15. The other end of the drainage channel 24 is connected to a drainage joint 27 and a drainage pipe 37 (FIG. 2) via a drainage electromagnetic valve 18. For example, the drainage channel 24 is opened with the mist solenoid valve 15 closed before the mist sauna operation is started, and is accumulated in the liquid heat exchanger 11 and the water supply channel 12 through the drainage channel 24. It will be possible to drain the water that is outside. The drainage channel 24 communicates with the air inflow channel 29 via a vacuum breaker (not shown) provided in the drainage solenoid valve 18, and the drainage solenoid valve is made to be in an atmospheric pressure state during drainage. Dirty water drained from 18 prevents backflow into the drainage channel 24.

  Each detection signal from the bathroom thermistor 16, the hot water thermistor 9, and the mist temperature thermistor 30 is sent to the control unit 4 (FIG. 10) realized by a microcomputer. The control unit 4 performs various operations such as mist sauna operation, cool air operation, and heating operation.

  The control operation of the control unit in the mist sauna operation is shown in the flowcharts of FIGS. 4 to 8 and the time chart of FIG. In addition, t1 of FIG. 9 is a time when the mist sauna switch is turned on, t2 indicates a bath temperature (temperature detected by a bath thermistor), respectively, t3 to t7 when the hot water temperature reaches 60 ° C. t3 is 24 ° C. or higher, t4 is 42 ° C., t5 is 42 ° C. or higher, t6 is 48 ° C., t7 is 45 ° C. or lower, and t8 is a timer count-up or stop switch ON.

  First, the bathroom temperature is set to a desired temperature with the bathroom remote controller 19 or the dressing room remote controller 35. For example, it sets in the range of 38 degreeC, 40 degreeC, 42 degreeC, 44 degreeC, and 46 degreeC. FIG. 9 shows a case where the bathroom temperature is set to 42 ° C.

  When the mist sauna switch is turned on (t1 in FIG. 9), the start of the mist sauna operation is commanded, the mist sauna operation mode lamp of the remote control is turned on, the heat source unit 6 is operated, and the thermal valve 8 is proportional to water. The valve 14 is opened to open the louver of the hot air outlet 32 (steps N1, N2, and N3). At this time, when 1 hour or more has elapsed since the previous mist sauna operation and the mist temperature thermistor detects 40 ° C. or less, the drain electromagnetic valve 18 and the water supply electromagnetic valve 17 are opened, and the purge operation is performed for about 30 seconds (steps N4 to N4). N11).

  Thereafter, when the detected temperature of the hot water thermistor becomes 60 ° C. or higher (t2 in FIG. 9), the circulation fan 22 is rotated (steps N15 to N17). Thereby, the hot air N is blown out into the bathroom 10. That is, the operation of the circulation fan 22 causes the air in the bathroom 10 to pass through the filter portion of the intake grille and be sucked into the heater body 1, to pass through the heat exchanger 33 for air conditioning to become hot air N, and from the hot air outlet 32 to the bathroom. 10 is blown out.

  Thereafter, when the bathroom thermistor detection temperature becomes 24 ° C. or higher (t3 in FIG. 9), the drain electromagnetic valve 18 is closed, the water supply electromagnetic valve 17 and the mist electromagnetic valve 15 are opened, and mist spraying is started (steps N12, N13a). , N13b, N14). In parallel with this, room temperature control including mist temperature setting is performed (steps N22 to N26).

  Here, only when the bathroom thermistor detection temperature is 15 ° C. or lower at the start of the mist sauna operation, the mist spray setting is set to 70 ° C. and the hot dash operation mode is executed (steps N18, N19, N20). The hot dash operation mode is a mode in which high-temperature mist at 70 ° C. is sprayed into the bathroom 10.

  Thereafter, when the bath thermistor detection temperature reaches 41 ° C. [set temperature T1 (42 ° C.) − 1 ° C.] (t4 in FIG. 9), the hot dash operation mode is terminated (step N22). That is, the value from the bathroom thermistor 16 is read, and the hot dash operation mode is automatically terminated when the bathroom thermistor detection temperature reaches the set temperature T1. In order to ensure safety management, if the detected temperature of the bathroom thermistor does not reach the set temperature T1 within 30 minutes from the start of hot dash operation, the hot dash operation mode is automatically terminated when 30 minutes have elapsed (step N21).

  When the hot dash operation mode ends, the mist sauna operation is performed in the temperature range of mist spraying (65 ° C. to 45 ° C.) in normal room temperature control. In the mist sauna operation of this example, the temperature range of mist spraying can be adjusted stepwise within a range of, for example, 65 ° C to 45 ° C. As a result, the body is warmed, a large amount of perspiration is promoted, fatigue and stress are relieved, a refreshing feeling is obtained, and further, blood flow promotion, metabolism enhancement, and in some cases, an effect useful for weight loss can be obtained.

  In this mist sauna operation, the bathroom temperature is controlled to a constant temperature by controlling the number of revolutions of the circulation fan 22 per unit time in accordance with the temperature detected by the bathroom thermistor, but the number of revolutions of the circulation fan 22 is temporarily changed. If the detected temperature of the bathroom thermistor rises, the opening of the water proportional valve 14 is adjusted to change the mist spray temperature stepwise. That is, after the bathroom temperature reaches the set temperature T1, the bathroom temperature is controlled by the circulation fan 22 by changing the air flow level of the circulation fan 22 (t5 to t8 in FIG. 9, step N23).

  Generally, as the air flow level of the circulation fan 22 is reduced, the heating output decreases, but the temperature of the blown air rises so that the heat of the hot air N is trapped in the vicinity of the ceiling in the bathroom 10. Since the bathroom thermistor 16 detects the temperature near the ceiling, the air flow level is gradually reduced and heated at a temperature higher than the set temperature in consideration of the temperature difference between the vicinity of the ceiling and the lower part of the bathroom 10 where the bather is present. By lowering the output, the temperature in the vicinity of the lower part of the bathroom 10 where the bather is present can be set to the set temperature as a result. Therefore, in this example, when the temperature deviation K (= bathroom temperature-set temperature) is in the range of −1 to +2, the air flow level of the circulation fan 22 is changed from the maximum air flow A1 according to the temperature deviation K as shown in FIG. It is changed in five steps (A1> A2> A3> A4> A5) up to the minimum airflow A5 (step N23). Specifically, when the temperature deviation K is 0, the air flow level is lowered by one step from A2 to A3, and when the temperature deviation K is +1, it is lowered by one step from A3 to A4. When the temperature deviation K is +2, it is lowered by one step from A4 to A5. When the temperature deviation K becomes +5 in the state finally lowered to the A5 stage, the heat valve 8 is fully closed to stop the heating of the heat exchanger 33 for air conditioning. The fan 22 rotates with a slight air volume of A5.

  As described above, when the temperature deviation K increases (in this example, the steps of +3 to +4) even if the air flow level of the circulation fan 22 is reduced, as shown in FIG. By narrowing the opening of the proportional valve 14, the mist spray temperature is changed in three steps [(B1 (65 ° C)> B2 (55 ° C)> B3 (45 ° C)), for example, in increments of 10 ° C. The opening of the water proportional valve 14 is adjusted so that the mist spray temperature becomes the target level by looking at the temperature level from the mist temperature thermistor 30. For example, when the temperature deviation K is +3, the opening of the water proportional valve 14 is adjusted. To reduce the mist spray temperature (mist spray temperature) from B1 to B2 by one step (step N23), and when the temperature deviation K is +4, the mist spray temperature is lowered by one step from B2 to B3. Even if K increases, B3 The mist spray 45 ° C.) are carried out. Such stepwise control of the rotational speed control and the mist spray temperature of the circulating fan 22, comprising a rise too or fall too temperature bath 10 can be prevented as much as possible.

  Thereafter, when the timer time ends (or when the stop switch is pressed), the mist sauna operation ends (t8 in FIG. 9, step N29). At this time, the mist sauna operation mode lamp is turned off, the heat source unit 6 is stopped, and the water supply electromagnetic valve 17, the heat valve 8 and the water proportional valve 14 are closed (step N30).

  When the operation is stopped due to the end of the timer time (t8 in FIG. 9), the drain electromagnetic valve 18 is opened for about 0.5 seconds to perform drain purge (steps N31 to N33). Further, pressure release control is performed for about 2 minutes until the hot water temperature becomes 60 or less (steps N34 and N35). Finally, the circulation fan 22 is stopped and the louver is closed (step N36).

  Thus, by executing the hot dash operation mode in which the high temperature mist of 70 ° C. is sprayed only when the bathroom thermistor detection temperature is low at the time of starting the mist sauna operation, the bathroom 10 can be quickly heated even in the cold winter season, Bath preparation time can be shortened. Even when a person enters the bathroom 10 during hot dash operation, the temperature of the mist and water droplets on the human body may increase due to the heat in the mist being taken away by the air in the bathroom 10 because the bathroom temperature is low. There is no worry that the bather feels uncomfortable with the heat. After that, when the bathroom temperature rises, the hot dash operation mode ends and the original mist sauna operation is performed, and switching to a low temperature mist of 65 ° C. or less is performed. There is no feeling of pleasure, and the elderly can enjoy a mist sauna bath with peace of mind. In other words, whether or not to execute the hot dash operation mode at the start of mist sauna operation is determined by the temperature detection temperature of the bathroom thermistor, so that the bather does not feel hot or uncomfortable and does not worry about burns Since the mist spraying temperature is adjusted with respect to the bathroom temperature at the start of mist sauna operation, it is possible to obtain a bathing environment in which a mist sauna bath can be enjoyed comfortably and safely in a short time. Since it is not necessary to raise or lower the mist spray temperature, the operability is excellent and safety can be sufficiently secured.

  In addition, by supplying hot air N during the hot dash operation mode, even when the bathroom temperature at the start of mist sauna operation is considerably low, such as in winter, high temperature mist and hot air of 70 ° C are used. Thus, the bathroom temperature can be rapidly increased, and a comfortable mist sauna space can be obtained in a short time. Therefore, it is effective for a mist sauna using both warm air N and mist spraying, and the bathroom 10 is heated by the warm air N, so that there is an advantage that the bathroom temperature can be increased efficiently even with a small amount of mist.

  Further, in this example, in normal room temperature control after the end of the hot dash operation mode, a method for adjusting the air flow level of the circulation fan 22 in a stepwise manner according to the bathroom thermistor detection temperature, and a method for adjusting the mist spray temperature in a stepwise manner. Therefore, it is possible to prevent the bathroom temperature from becoming too high or too low during the mist sauna bath as much as possible, and there is an advantage that the mist sauna bath becomes more comfortable.

  The mist sauna apparatus of the present invention can be widely applied to mist spraying on a shower unit partitioned from a bathtub in the bathroom 10 or mist spraying on a sauna room independent of the bathroom 10.
