Description

  The present invention relates to a mist sauna device for spraying mist having different roughness on a bathroom and a bathroom heating dryer with a mist sauna function.

  Bathing has the effect of healing the fatigue of your body or relaxing and improving your mood. The bathing method preferred by the user varies depending on the season, physical condition, mood and the like. Therefore, even in the home bath, if the bathing method can be changed according to the user's preference, the daily bath time can be made more comfortable.

  In recent years, mist sauna bathing, which is excellent in water retention, sweating, heat retention, relaxation effect, etc., has attracted attention as one of the bathing methods. The mist sauna bathing is performed by spraying mist into the bathroom from the mist sauna apparatus so that the bathroom is in the mist sauna state. In mist sauna bathing, the comfort felt by the user varies depending on the particle size of the mist. Specifically, for example, in the case of a coarse mist having a large average particle size, the user receives a pleasant stimulus when the mist hits the skin, and the skin gets wet and warms from the core of the body, so that the heat retaining effect is maintained. An effect is obtained. On the other hand, for example, in the case of a fine mist having a small average particle diameter, the user can obtain an effect of perspiring sufficiently without getting wet in the bathroom or body. Therefore, conventionally, a mist sauna apparatus has been proposed in which mists having different roughness are sprayed on the bathroom.

  For example, a bathroom mist generating system described in Patent Document 1 includes a mist nozzle for generating a coarse mist having a large average particle diameter and a mist generating mechanism for generating a fine mist having a small average particle diameter.

  FIG. 10 is a cross-sectional view of a mist sauna device 211 described in Patent Document 2. For example, in the mist sauna device 211 described in Patent Document 2, the particle size of the mist sprayed from the mist nozzle 212 is changed by changing the pressurization amount of the pump 214 provided in the water supply path 213 connected to the mist nozzle 212. Is changing. The mist sprayed from the mist nozzle 212 is diffused in the bathroom 201 on the air sent from the blower 215. In the mist sauna device 211 described in Patent Document 2, even when the control unit 216 changes the directivity of the blower 215 in conjunction with the pressurization amount of the pump 214, the pressurization amount of the pump 214 is reduced. The mist is diffused in the bathroom 201 so that the spray range can be adjusted and the flow rate of the mist can be accelerated.

  However, the bathroom mist generation system described in Patent Document 1 has a large number of parts and is large because it includes a mist nozzle and a mist generation mechanism to generate mists having different particle sizes.

  The mist sauna device 211 described in Patent Document 2 changes the particle size of mist generated from the mist nozzle 212 according to the pressurization amount of the pump 214. However, a blower 215 is required to adjust the spray range and flow rate of mist. Even if the blower 215 is shared with the bathroom heater / dryer, control for interlocking the operations of the blower 215 and the pump 214 is required depending on the mode selected by the user. Therefore, the mist sauna device 211 described in Patent Document 2 requires a complicated control of the blower 215 and the pump 214 in order for the control means 216 to generate mists having different roughnesses, and has become large.

  The present invention has been made to solve the above problems, and provides a small mist sauna apparatus and a bathroom heating dryer with a mist sauna function that can adjust the roughness of mist with a simple configuration. With the goal.

One embodiment of the present invention has the following configuration.
(1) In a mist sauna apparatus that sprays mist having different roughness on a bathroom, a fluid mixing nozzle that mixes and ejects two kinds of fluids, and is connected to the fluid mixing nozzle, and hot water for mist is supplied to the fluid mixing nozzle. Hot water supply pipe for mist to be supplied, an air supply pipe connected to the fluid mixing nozzle and supplying air to the fluid mixing nozzle, and a pressure of the air connected to the air supply pipe and supplied to the fluid mixing nozzle Air pressure adjusting means for adjusting the pressure, and control means for controlling the air pressure adjusting means to change the pressure of the air supplied to the fluid mixing nozzle to generate mist having different roughness on the fluid mixing nozzle; Have

(2) In the configuration described in (1), preferably, the fluid mixing nozzle ejects the mist hot water supplied from the mist hot water supply pipe to generate the mist.

(3) In the configuration described in (1) or (2), preferably, the fluid mixing nozzle has mode switching means for switching a plurality of modes having different average particle diameters of the mist, and the control means , For each of the plurality of modes, mode storage means for storing the pressure of the air to be adjusted by the air pressure adjustment means.

(4) In the configuration described in (3), the plurality of modes include a splash mist mode having an average particle size that makes the mist generated by the fluid mixing nozzle feel against the skin, and the fluid mixing. The mist generated by the nozzle does not feel that it hits the skin, but has a silky mist mode having an average particle size enough to wet the book, and the mist generated by the fluid mixing nozzle does not feel that it hits the skin, and , A micro mist mode having an average particle size that does not wet the book.

(5) In the configuration described in (1) or (2), it has a particle size setting unit that sets a particle size of the mist generated by the fluid mixing nozzle, and the control unit includes a particle size of the mist. The particle size / pressure relationship defining data defining the relationship with the air pressure to be adjusted by the air pressure adjusting means is stored.

(6) A bathroom heating dryer with a mist sauna function, comprising the mist sauna device according to any one of (1) to (5).

The mist sauna apparatus configured as described above is a mist sauna apparatus that sprays mist having different roughness on a bathroom, and is connected to a fluid mixing nozzle that mixes and ejects two kinds of fluids, and a fluid mixing nozzle. Hot water supply pipe for mist supplying hot water, an air supply pipe connected to the fluid mixing nozzle and supplying air to the fluid mixing nozzle, an air supply pipe connected to the fluid mixing nozzle, and adjusting the pressure of the air supplied to the fluid mixing nozzle Air pressure adjusting means, and control means for controlling the air pressure adjusting means to change the pressure of the air supplied to the fluid mixing nozzle to generate mist having different roughness in the fluid mixing nozzle. If the control means controls the pressure of the air supplied from the air supply pipe to the fluid mixing nozzle, the roughness of one fluid mixing nozzle is different. It is possible to generate a mist. And since the mist is generated by mixing hot water for mist with air of a predetermined pressure, the mist can be diffused without providing a blower. Therefore, according to the mist sauna apparatus of the said structure, the roughness of mist can be adjusted with a simple structure, and apparatus size can be made small.

  Further, in the mist sauna device having the above configuration, the fluid mixing nozzle ejects the entire amount of hot water for mist supplied from the hot water supply pipe for mist to generate mist, so that the hot water for mist that has not become mist is drained. For this reason, it is possible to save the cost of drainage work for installing a dedicated drainage system and the construction of the drainage system.

  Further, the mist sauna device having the above configuration has mode switching means for switching a plurality of modes in which the average particle diameter of the mist generated by the fluid mixing nozzle is different, and the control means adjusts the air pressure adjusting means for each of the plurality of modes. Since the mode storage means for storing the air pressure is provided, the air pressure to be adjusted by the air pressure adjusting means can be quickly obtained in accordance with the mode set in the mode switching means.

  In the mist sauna apparatus having the above-described configuration, the plurality of modes include a splash mist mode having an average particle diameter that makes it feel that the mist generated by the fluid mixing nozzle hits the skin, and the mist generated by the fluid mixing nozzle. The silky mist mode has an average particle size that does not feel that it touches the skin but wets the book, and the average particle that does not feel that the mist generated by the fluid mixing nozzle hits the skin and does not wet the book Since the micro mist mode has a diameter, the user can easily change the mist sauna bathing pattern in accordance with the temperature, physical condition, mood and the like.

  Further, the mist sauna device having the above configuration has a particle size setting means for setting the particle size of the mist generated by the fluid mixing nozzle, and the control means includes a mist particle size and an air pressure to be adjusted by the air pressure adjusting means. Since the particle size / pressure relationship regulation data that defines the relationship of the air pressure is stored, the air pressure adjusting means quickly adjusts the air pressure to be adjusted according to the particle size of the mist arbitrarily set in the particle size setting means. Can be sought. Moreover, since the particle diameter of mist can be changed in a stepless manner according to the user's feeling, it is easy to realize mist sauna bathing that the user desires.

  Moreover, since the bathroom heater / dryer with a mist sauna function having the above-described configuration includes the mist sauna device having the above-described configuration, an increase in the size of the device can be suppressed even if the mist sauna function is added.

  Hereinafter, preferred embodiments according to the present invention will be described with reference to the drawings.

<Example of installation of bathroom heating dryer>
FIG. 9 is a diagram illustrating an example of the bathroom 1 in which the bathroom heater / dryer 11 with a mist sauna function according to the embodiment of the present invention is installed. The bathroom heater / dryer 11 is attached to the ceiling 2 of the bathroom 1. The bathroom heater / dryer 11 has a drying function for drying the bathroom 1, a heating function for heating the bathroom 1, a ventilation function for ventilating the bathroom 1, and the bathroom 1. It has a mist sauna function to make it a mist sauna state. The user selects the function of the bathroom heater / dryer 11 via a remote controller (an example of mode switching means) 12 provided on the wall 3 of the bathroom 1 or in the kitchen, etc., and selects a bathing method according to physical condition, temperature, mood, etc. Can be set.

<Composition of bathroom heating dryer>
FIG. 1 is a diagram showing a schematic configuration of a bathroom heater / dryer 11. The bathroom heater / dryer 11 is provided with a blower 13, a ventilation fan 19, and a mist sauna device 31 in a main body case 20.

  The bathroom heater / dryer 11 is connected to a bathroom heat exchanger 15 and a heat source machine (not shown) via a bathroom heat medium circulation pipe 22, and heat medium (for example, hot water) heated by the heat source machine is used for heat exchange for the bathroom. The bathroom heat exchanger 15 is heated by circulating in the vessel 15. The bathroom heat medium circulation pipe 22 is provided with a bathroom heat medium control valve 26 to control the circulation of the heat medium to the bathroom heat exchanger 15. When the bathroom 1 is heated, the bathroom heat exchanger 15 is preheated by opening the bathroom heat medium control valve 26 to circulate the heat medium in the bathroom heat exchanger 15. When the preheating of the bathroom heat exchanger 15 is completed, the blower 13 is driven. Then, the air in the bathroom 1 is sucked into the main body case 20 from the suction port 14, heated by the bathroom heat exchanger 15, and then sent out from the blower port 17 to the bathroom 1 through the ventilation path 16. Increase room temperature. When the room temperature of the bathroom 1 reaches the set temperature, the bathroom heater / dryer 11 sends warm air into the bathroom 1 so as to maintain the temperature.

  In addition, when drying the bathroom 1, the bathroom heater / dryer 11 drives the ventilation fan 19, sucks the air in the bathroom 1 into the main body case 20 from the exhaust port 18, and discharges it to the exhaust pipe 21.

<Configuration of mist sauna device>
The mist sauna device 31 is configured to generate mist by mixing mist hot water adjusted in temperature by the mist heat exchanger 33 with air of a predetermined pressure and ejecting the mixture from the fluid mixing nozzle 32. The fluid mixing nozzle 32 itself can diffuse the mist by the pressure of the air, but is further disposed in the vicinity of the air blowing port 17 so that the mist can be diffused to the corner of the bathroom 1. The mist sauna device 31 changes the pressure of air supplied to the fluid mixing nozzle 32 so that the fluid mixing nozzle 32 generates mist having different roughness.

  A water supply pipe 24, a mist heat medium circulation pipe 23, and a mist hot water supply pipe 34 are connected to the mist heat exchanger 33. The water supply pipe 24 is a pipe that supplies tap water to the mist heat exchanger 33 with the water pressure of the water pipe. The mist heat medium circulation pipe 23 branches from the bathroom heat medium circulation pipe 22 and is connected to a mist heat exchanger 33. The mist heat medium circulation pipe 23 heats the mist heat exchanger 33 by supplying a heat medium heated by a heat source device (not shown) to the mist heat exchanger 33, and recovers heat by the mist heat exchanger 33. This is a pipe for sending the heat medium returned to a heat source machine (not shown) through the bathroom heat medium circulation pipe 22. The mist heat medium circulation pipe 23 is provided with a mist heat medium control valve 27 to control the circulation of the heat medium to the mist heat exchanger 33. The mist hot water supply pipe 34 is a pipe that connects the mist heat exchanger 33 and the fluid mixing nozzle 32 and supplies the mist hot water adjusted in temperature by the mist heat exchanger 33 to the fluid mixing nozzle 32. A mist hot water supply pipe 34 is provided with a mist solenoid valve 35 to control the supply of mist hot water to the fluid mixing nozzle 32.

  The air supply pipe 36 is a pipe that is connected to the fluid mixing nozzle 32 and supplies air to the fluid mixing nozzle 32. Connected to the air supply pipe 36 is a compressor (an example of air pressure adjusting means) 38 that adjusts the air supplied from the air supply pipe 25 to the fluid mixing nozzle 32 via the air pressure supply pipe 36 to a predetermined pressure. An air supply proportional valve 37 is disposed upstream of the compressor 38 to control the pressure of air supplied to the compressor 38. For example, if the air can be controlled to a predetermined pressure such as a blower, the compressor 38 can be substituted.

<Schematic configuration of mist nozzle>
The fluid mixing nozzle 32 is configured by a well-known fluid mixing nozzle that mixes and ejects a gas and a liquid. Known fluid mixing nozzles include those described in JP-A-2002-126585, those described in JP-A-2011-98284, and those described in JP-A-2011-62583. It has been.

  FIG. 2 is a cross-sectional view showing a schematic configuration of the fluid mixing nozzle 32. The fluid mixing nozzle 32 includes a gas supply unit 321 that supplies gas, a gas supply passage 322 that distributes gas from the gas supply unit 321 to the gas orifice 323 of the gas injection unit, and a liquid that flows into the fluid orifice 325 of the liquid injection unit. The fluid orifice 325 circulates, and the fluid orifice 325 is disposed inside the gas orifice 323. In the fluid mixing nozzle 32, an air supply pipe 36 is connected to the gas supply part 321, and a hot water supply pipe 34 for mist is connected to the fluid circulation part 324.

  FIG. 3 is a diagram showing the relationship between the air pressure and the estimated mist average particle diameter when tap water supply piping is connected to the fluid mixing nozzle 32 shown in FIG. The vertical axis represents the estimated mist average particle diameter (μm), and the horizontal axis represents the air pressure (kPa). When air is not supplied to the fluid mixing nozzle 32 (when the air pressure is 0 kPa), the average particle diameter of the mist to be ejected is estimated to be 100 μm. In addition, when the fluid mixing nozzle 32 is supplied with 34 kPa of air, the average particle diameter of the mist to be ejected is estimated to be 10 μm, and when supplied with 66 kPa of air, the average particle diameter of the mist is estimated to be 1 μm. The Thus, the fluid mixing nozzle 32 is considered to have a smaller average particle diameter of mist as the supplied air has a higher pressure.

  The fluid mixing nozzle 32 ejects tap water from the fluid orifice 325 toward the center of the air ejected from the gas orifice 323. When the tap water is sprayed from the fluid orifice 325, the tap water is finely granulated, and further refined by the force of the air ejected from the gas orifice 323. Therefore, the fluid mixing nozzle 32 can generate mist having a smaller average particle diameter as the pressure of supplied air is higher. Then, the fluid mixing nozzle 32 spreads and diffuses the fine mist on the air ejected from the fluid orifice 323.

  FIG. 4 shows the relationship between the water pressure / flow rate, the air pressure / flow rate, the sensitivity test result, and the estimated average particle size of the mist when the mist is ejected from the fluid mixing nozzle 32 at room temperature of 20 ° C. FIG. The inventors further provide a sensor for measuring the pressure and flow rate of water ejected from the fluid mixing nozzle 32 and a sensor for measuring the pressure and flow rate of air ejected from the fluid mixing nozzle 32 upstream of the fluid mixing nozzle 32. Attached to the side, an experimental device was made. Then, in an environment of room temperature of 20 ° C., tap water is supplied to the fluid circulation part 324 of the fluid mixing nozzle 32 with the water pressure of the water pipe, and the air supplied to the fluid mixing nozzle 32 without controlling the pressure of the tap water. The mist was ejected from the fluid mixing nozzle 32 while changing only the pressure.

  As a result, when air is not supplied to the fluid mixing nozzle 32 (when the air pressure is 0 kPa and the flow rate is 0 l / min), the tap water pressure is 0.09 MPa and the tap water flow rate is 47.5 ml / min. It was. The result of the sensitivity test was that the mist felt that it touched the skin. The average particle size of the mist at this time is estimated to be greater than 10 μm and not greater than 100 μm.

  When the air pressure was controlled to 34 kPa, the tap water pressure was 0.05 MPa, the tap water flow rate was 40.0 ml / min, and the air flow rate was 1.8 l / min. The result of the sensitivity test was that the mist did not feel the skin but the book was wet. The average particle size of the mist at this time is estimated to be greater than 1 μm and 10 μm or less.

  When the air pressure was controlled to 66 kPa, the tap water pressure was 0.06 MPa, the tap water flow rate was 31.7 ml / min, and the air flow rate was 4.8 l / min. The result of the sensitivity test was that the mist did not feel the skin and the book did not get wet. The average particle diameter of the mist at this time is estimated to be 1 μm or less.

  It is estimated that the fluid mixing nozzle 32 ejects a mist larger than 10 μm and not larger than 100 μm even without air pressure. In addition, when the fluid mixing nozzle 32 is increased to 34 kPa from a state in which no air is supplied (when the air pressure is 0 kPa), the flow rate of air increases from 0 l / min to 1.8 l / min by about a factor of two. The water pressure is almost halved from 0.09 MPa to 0.05 MPa, and the flow rate of tap water is reduced by about 15% from 47.5 ml / min to 40.0 ml / min. In addition, when the fluid mixing nozzle 32 increases the air pressure from 34 kPa to 66 kPa approximately twice, the air flow rate increases approximately 1.8 times from 1.8 l / min to 4.8 l / min. Is slightly increased from 0.05 MPa to 0.06 MPa, and the flow rate of tap water is decreased by about 20% from 40.0 ml / min to 31.7 ml / min.

  Thus, since the size of the gas orifice 323 is determined in the fluid mixing nozzle 32, the flow rate of tap water decreases as the air pressure increases. However, the fluid mixing nozzle 32 has a smaller decrease amount of the tap water flow rate than the increase amount of the air pressure / flow rate. For this reason, it is considered that the fluid mixing nozzle 32 can change the average particle diameter of the mist without changing much the amount of mist ejected even if the pressure of the supplied air fluctuates.

  Therefore, if the mist sauna apparatus 31 uses the fluid mixing nozzle 32 to control only the pressure of the air supplied to the fluid mixing nozzle 32 without controlling the pressure of hot water for mist, the amount of mist sprayed can be reduced. The average particle size of the mist can be changed without much change.

  By the way, the fluid mixing nozzle 32 is controlled so that the pressure of the supplied air is within a low pressure range of 0 kPa to 100 kPa, preferably 0 kPa to 80 kPa, and more preferably 0 kPa to 70 kPa. The diameter can be changed. On the other hand, the reason why the mist sauna device 31 changes the roughness of the mist is to change the effect given to the user when taking a mist sauna bath. Human sensitivity is inferior to precision machines. Therefore, the average particle diameter of the mist generated by the mist sauna device 31 does not need to be strictly managed as in car painting. Therefore, a commercially available small compressor can be used as the compressor 38 for adjusting the pressure of the air supplied to the fluid mixing nozzle 32, which contributes to the miniaturization of the mist sauna device 31. In the present embodiment, a small hobby compressor used when spraying paint on a plastic model is applied to the compressor 38.

  The operation of the bathroom heater / dryer 11 and the mist sauna device 31 is controlled by the control means 41 shown in FIG. 1 in accordance with the operation of the remote controller 12 shown in FIGS.

<Configuration of remote control>
5 and 6 are front views of the remote controller. The remote controller 12 includes a liquid crystal display screen 12a, a remote control power ON / OFF switch 12b, a determination operation button 12c, an upper operation button 12d, a lower operation button 12e, a left operation button 12f, and a right operation. A button 12g is provided. The liquid crystal display screen 12a displays the operation content of the operation buttons 12c to 12g, the setting content of the bathroom heating dryer 11, and the like. By operating the operation buttons 12c to 12g, the user can select the function of the bathroom heater / dryer 11, and can set / change room temperature, hot water temperature, and the like. Further, the user can switch between a plurality of modes in which the average particle diameter of the mist generated by the fluid mixing nozzle 32 is different by operating the operation buttons 12c to 12g. In the present embodiment, the plurality of modes are a splash mist mode having an average particle size that makes it feel that the mist generated by the fluid mixing nozzle 32 hits the skin, and the mist generated by the fluid mixing nozzle 32 hits the skin. The silky mist mode has an average particle size that does not feel that it wets the book, and the average particle size that does not make the mist generated by the fluid mixing nozzle 32 touch the skin and does not wet the book. It has a micro mist mode.

<Block configuration of control means>
FIG. 7 is a block diagram of the control means 41. The control means 41 is a known microcomputer, and includes a central processing unit (CPU) 42 for processing and calculating data, a memory 43 for storing data and programs, an input / output interface 44 for controlling input / output of data, and the like. Is provided.

  The input / output interface 44 includes a remote control 12, a blower 13, a ventilation fan 19, a bathroom heat medium control valve 26, a mist heat medium control valve 27, a mist electromagnetic valve 35, a supply proportional valve 37, a compressor 38, and the like. It is connected so that electric signals can be transmitted and received.

  The memory 43 is provided with a storage area for mode storage means 45. The mode storage means 45 stores an air pressure setting table for storing air pressure to be adjusted by the compressor 38 for each mode. The air pressure setting table is provided for each room temperature of the bathroom 1. This is because the average particle diameter of the mist sprayed from the fluid mixing nozzle 32 becomes finer as the room temperature of the bathroom 1 is higher. In other words, even if the hot water for mist and the pressure of air are constant, the average particle diameter of the mist sprayed from the fluid mixing nozzle 32 differs depending on the room temperature of the bathroom 1.

  FIG. 8 is a diagram showing an example of an air pressure setting table at a room temperature of 20 ° C. When the room temperature of the bathroom 1 is 20 ° C., if the user sets the splash mist mode on the remote controller 12, the air is not supplied to the fluid mixing nozzle 32 (the air pressure is set to 0 kPa). When the room temperature of the bathroom 1 is 20 ° C., when the user sets the silky mist mode on the remote controller 12, the pressure of the air supplied to the fluid mixing nozzle 32 is set to 34 kPa. When the room temperature of the bathroom 1 is 20 ° C., when the user sets the micro mist mode on the remote controller 12, the pressure of the air supplied to the fluid mixing nozzle 32 is set to 66 kPa.

<Description of operation>
Then, operation | movement of the bathroom heating dryer 11 is demonstrated. As shown in FIG. 5, the user operates the operation buttons 12c to 12g while viewing the liquid crystal display screen 12a of the remote controller 12, and selects the mist sauna function. Then, as shown in FIG. 6, the user operates the operation buttons 12c to 12g to switch the mode.

  When the mode of the mist sauna function is set, the control means 41 switches the bathroom heat medium control valve 26 and the mist heat medium control valve 27 from the valve closed state to the valve open state. Thereby, the heat medium circulates in the heat exchanger 15 for bathroom and the heat exchanger 33 for mist, and is preheated. When the preheating of the bathroom heat exchanger 15 and the mist heat exchanger 33 is completed, the control means 41 drives the blower 13. Then, the bathroom heating dryer 11 sucks the air in the bathroom 1 from the suction port 14, warms it with the heat exchanger 15 for the bathroom, and sends it out from the blower port 17 to the bathroom 1. Thereby, the room temperature of the bathroom 1 rises.

  The control means 41 reads out the air pressure from the mode storage means 45 using the temperature of the bathroom 1 and the mode set by the remote controller 12 as arguments, and controls the supply proportional valve 37 and the compressor 38 so as to obtain the read air pressure. While controlling the operation, the mist solenoid valve 35 is opened to supply hot water for mist to the fluid mixing nozzle 32.

  Specifically, when the user sets the splash mist mode on the remote controller 12, the control means 41, for example, when the temperature of the bathroom 1 is 20 ° C., the splash mist is based on the air pressure setting table shown in FIG. The air pressure corresponding to the mode is determined to be 0 kPa. Then, the control means 41 switches the mist electromagnetic valve 35 from the valve closed state to the valve open state with the air supply proportional valve 37 closed and the compressor 38 not driven. The fluid mixing nozzle 32 ejects only the hot water for mist adjusted to the set temperature by the heat exchanger 33 for mist from the fluid orifice 325 to the bathroom 1 through the gas orifice 323. Since the hot water for mist is ejected only at the flow velocity accelerated by the fluid orifice 325, it becomes a coarse mist having an average particle size larger than 10 μm and not larger than 100 μm, and diffuses into the bathroom 1. When the user bathes in the splash mist mode, the mist is stimulated when it falls on the skin, a pleasant massage effect is obtained, and the body is firmly wet and warmed from the core.

  When the user sets the silky mist mode in the remote controller 12, for example, when the temperature of the bathroom 1 is 20 ° C., the control unit 41 sets the air corresponding to the silky mist mode based on the air pressure setting table shown in FIG. Is determined to be 34 kPa. The control means 41 switches the mist solenoid valve 35 and the air supply proportional valve 37 from the valve closed state to the valve open state, and pressurizes the air supplied from the air supply pipe 25 to the compressor 38 to 34 kPa. 38 is driven. The fluid mixing nozzle 32 ejects hot water for mist adjusted to a set temperature by the heat exchanger 33 for mist together with air pressurized to 34 kPa by the compressor 38. The hot water for mist is pulverized by being entrained in an air stream, becomes a fine mist having an average particle size of more than 1 μm and not more than 10 μm, and diffuses into the bathroom 1 as if wrinkled. When the user takes a bath under the silky mist mode, a massage effect that is less irritating than the splash mist mode is obtained, and the body is moistened to obtain a moisturizing effect.

When the user sets the micro mist mode in the remote controller 12, for example, when the temperature of the bathroom 1 is 20 ° C., the control unit 41 sets the air corresponding to the micro mist mode based on the air pressure setting table shown in FIG. Is determined to be 66 kPa. The control means 41 switches the mist solenoid valve 35 and the air supply proportional valve 37 from the valve closed state to the valve open state, and pressurizes the air supplied from the air supply pipe 25 to the compressor 38 to 66 kPa. 38 is driven. The fluid mixing nozzle 32 ejects hot water for mist adjusted to a set temperature by the heat exchanger 33 for mist together with air pressurized to 66 kPa by the compressor 38. Since the pressure of the air is higher than the pressure in the silky mist mode, the hot water for mist is blown into the gas blown out from the gas orifice 323 more vigorously than the silky mist mode, and the average particle size is 1 μm or less. Become a micro mist. The micro mist rides on the warm air sent out from the blower port 17 and diffuses softly throughout the bathroom 1. At this time, since the mist is fine, the user's field of view is good. When the user takes a bath under the micro mist mode, sweating is promoted without getting wet in the bathroom 1 or the body, and the user can take a bath while relaxing by reading in the bathroom 1.

  When the mist sauna function is terminated due to the operation of the remote controller 12 or the mist sauna bathing set time, the control means 41 changes the bathroom heat medium control valve 26 and the mist heat medium control valve 27 from the valve open state to the valve closed state. The heating of the bathroom heat exchanger 15 and the mist heat exchanger 33 is completed. Then, the mist ejection is finished by closing the mist solenoid valve 35 and the air supply proportional valve 37 and stopping the compressor 38. And the air blower 13 is stopped and sending out of warm air is complete | finished.

  Here, the role of the mist in the mist sauna bath is to obtain a water retention effect, a moisture retention effect, a sweat effect, a massage effect, and the like. Therefore, the average particle diameter of the mist may be more varied than that of the car coating apparatus. Therefore, the control means 41 of the mist sauna device 31 does not perform feedback control by detecting the pressure of hot water or air for mist supplied to the fluid mixing nozzle 32 with a sensor, but controls the operation of the compressor 38 to control the air. The average particle diameter of the mist is changed only by changing the pressure.

  In addition, in the said description, although the case where the bathroom 1 was heated was demonstrated, when bathing the mist sauna with room temperature without heating the bathroom 1, leaving the bathroom heat medium control valve 26 in a valve-closed state, The mist heat medium control valve 27, the mist electromagnetic valve 35, and the air supply proportional valve 37 are switched from the valve closed state to the valve open state, the compressor 38 is driven, and the mist is sprayed from the fluid mixing nozzle 32. good.

  When the mist is bathed without heating the tap water, the tap water in the water supply pipe 24 is passed through the mist electromagnetic valve 35 while the mist heat medium control valve 27 is closed. What is necessary is just to make it supply to the fluid mixing nozzle 32. FIG.

<Effect>
As described above, the mist sauna device 31 according to the present embodiment includes the fluid mixing nozzle 32 that mixes and ejects two types of fluid in the mist sauna device 31 that sprays mist having different roughness on the bathroom 1, and the fluid A hot water supply pipe 34 for mist that is connected to the mixing nozzle 32 and supplies hot water for mist to the fluid mixing nozzle 32; an air supply pipe 36 that is connected to the fluid mixing nozzle 32 and supplies air to the fluid mixing nozzle 32; A compressor (an example of an air pressure adjusting means) 38 that is connected to the supply pipe 36 and adjusts the pressure of the air supplied to the fluid mixing nozzle 32, and changes the pressure of the air supplied to the fluid mixing nozzle 32 by controlling the compressor 38. Control means 41 for generating mist with different roughness at the fluid mixing nozzle 32, the compressor 38 is supplied with air supply and distribution. By controlling the control unit 41 to adjust the pressure of air supplied to the fluid mixing nozzle 32 from 36, it is possible to generate a roughness different mist from one fluid mixing nozzle 32. And since hot water for mist is mixed with air of a predetermined pressure to generate mist, the mist can be diffused into the bathroom 1 without providing the blower 215 as in the conventional mist sauna device 211 shown in FIG. Can do. Therefore, according to the mist sauna apparatus 31 of the said structure, the roughness of mist can be adjusted with a simple structure, and apparatus size can be made small.

  In the mist sauna device 31 configured as described above, since the fluid mixing nozzle 32 ejects the entire amount of hot water for mist supplied from the hot water supply pipe 34 for mist to generate mist, hot water for mist that has not become mist. It is possible to save the cost of drainage work for installing a dedicated drainage system for draining water and the construction of the drainage system.

  The mist sauna device 31 having the above-described configuration includes a remote controller (mode switching unit) 12 that switches a plurality of modes in which the average particle diameter of the mist generated by the fluid mixing nozzle 32 is different. Since the mode storage means 45 for storing the air pressure to be adjusted by the compressor 38 is provided, the air pressure to be adjusted by the compressor 38 can be quickly obtained according to the mode set in the remote controller 12.

  In the mist sauna device 31 having the above-described configuration, the plurality of modes include a splash mist mode having an average particle size that makes it feel that the mist generated by the fluid mixing nozzle 32 hits the skin, and the fluid mixing nozzle 32 generates. The mist generated by the fluid mixing nozzle 32 does not feel that the mist generated by the fluid mixing nozzle 32 touches the skin and does not wet the book. Since it is a micro mist mode having an average particle size, the user can easily change the mist sauna bathing pattern according to the temperature, physical condition, mood and the like.

  Moreover, since the bathroom heater / dryer 11 with the mist sauna function having the above-described configuration includes the mist sauna device 31 having the above-described configuration, an increase in the size of the device can be suppressed even if the mist sauna function is added.

  In addition, this invention is not limited to the said embodiment, Various application is possible.

(1) For example, in the said embodiment, although the mist sauna apparatus 31 was integrated in the bathroom heating dryer 11, you may make it assemble the mist sauna apparatus 31 in the bathroom 1 independently. In this case, the mist sauna device 31 may be retrofitted to the ceiling 2 of the bathroom 1 or the wall surface 3 of the bathroom 1. When the mist sauna device 31 is retrofitted to the wall surface 3 of the bathroom 1, for example, the mist sauna device 31 is mounted at a height that can be reached by a user sitting on a chair and the mist sauna device 31 descends to the user. It is better to generate mist as if it is applied. This is because the mist can be sprayed on the user at a shorter distance than the case where it is installed on the ceiling 2 and the effectiveness of the mist sauna bath such as heat retention, moisture retention, sweating, and relaxation can be enhanced.

(2) For example, in the above embodiment, the air pressure is controlled stepwise according to the mode set in the remote controller 12. On the other hand, the average particle size of the mist generated by the fluid mixing nozzle is set in the remote controller 12, and the control means 41 defines the relationship between the particle size of the mist and the air pressure adjusted by the compressor. It is good to store the prescribed data. The particle size / pressure relationship regulation data may be constituted by, for example, data shown in FIG. In this case, when the user arbitrarily sets the average mist particle size in the remote controller 12, the control means 41 quickly reads out the air pressure from the particle size / pressure relationship defining data and controls the compressor 38. According to this, it is possible to quickly obtain the air pressure according to the particle size of the mist arbitrarily set in the remote controller 12. Moreover, since the particle diameter of mist can be changed in a stepless manner according to the user's feeling, it is easy to realize mist sauna bathing that the user desires.

(3) In the above embodiment, a plurality of modes in which the average particle diameter of mist is fixed are provided. However, a mode in which the average particle diameter of mist is automatically changed may be set. In this case, it is possible to change the stimulation when the mist hits the user and obtain a higher massage effect.

(4) In the above embodiment, the plurality of modes are the splash mode, the silky mode, and the micro mist mode. However, two or more modes may be used.

(5) In the above-described embodiment, the mode is divided according to the sensitivity. However, the mode may be divided based on another standard such as an average particle diameter of mist.

(6) In the above embodiment, the roughness of the fluid mixing nozzle 32 differs by controlling the pressure of the air supplied to the fluid mixing nozzle 32 by controlling only the compressor 38 without controlling the pressure of the hot water for mist. Control means 41 for generating mist is provided. On the other hand, the control means 41 may cause the fluid mixing nozzle 32 to generate mists having different roughnesses by controlling both the hot water for mist and the pressure of the air.

(7) In the above embodiment, the nozzle for mixing and ejecting the gas and the fluid is the fluid mixing nozzle 32. However, if the hot water for mist can be misted and ejected, the gas and the gas or the liquid and the liquid can be ejected. A nozzle that is mixed and ejected may be applied to the fluid mixing nozzle 32.
