Description

  The present invention is directed to a mist generating system for a bathroom which is used for the purpose of mist formation (mist formation, fine particle formation) of hot water, for example, performing a mist sauna bath or taking a mist shower, and a bathroom provided with the same It relates to an air conditioner.

  Conventionally, as an example of mist generating means installed in a bathroom for a mist sauna, there is one using two types of mist nozzles (see, for example, Patent Document 1). Both of the two types of mist nozzles are so-called spray nozzles. When hot water is supplied from an external heat source device such as a hot water supply device, it can be misted and ejected into the bathroom. When the hot water mist is ejected into the bathroom, a heating effect is obtained. Bathers can also take a mist shower. The two types of mist nozzles can generate two types of mists having different particle sizes, and a bather can take a mist having a relatively small particle size relatively comfortably.

  However, the prior art has still to be improved as described below.

  That is, when a mist having a small particle size is ejected, it may be desired to make the mist have a particle size as small as possible. For example, when a bather takes a mist shower, the smaller the mist particle size, the gentler the mist acts on the bather's skin, so the bather requests such a mist shower. Can be considered. On the other hand, in the prior art, since only two types of mist nozzles are used as means for generating two types of mist having different particle sizes, mist having a very small particle size is used. It is difficult to generate. More specifically, the mist nozzle generates a high-speed swirling flow of hot water supplied toward the mist nozzle in the mist nozzle, and discharges the hot water vigorously from a small-diameter tip opening to generate hot water. Generally, it is configured to be atomized. However, with such a configuration, it is difficult to generate a mist having a minute particle size, and there is room for improvement in this respect.

  Conventionally, there are devices described in Patent Documents 2 and 3 as negative ion generators. The devices described in these documents use a centrifugal force of a rotatable rotor to scatter hot water around the rotor and cause this water to collide with a collision wall provided around the rotor. Is configured to generate. The present inventors have conceived of using such a device as a mist generating device for a bathroom. However, in the negative ion generator described in Patent Documents 2 and 3, the mist generated in the casing housing the collision wall and the rotor is not immediately ejected to the outside of the casing. After passing through a relatively long path in the casing, it is ejected to the outside of the casing. In this case, before most of the mist is ejected to the outside of the apparatus, it contacts the wall surface of the casing to form water droplets. Therefore, the amount of mist ejected is small, and it is not suitable for use in a mist sauna bath or mist shower in the bathroom.

JP 2004-245554 A JP 2003-339817 A JP 2001-289470 A

  The present invention has been conceived under the circumstances as described above, and is capable of generating mists having different roughness, and in the case of generating mists having a small particle size, It is an object of the present invention to provide a bathroom mist generation system capable of efficiently and suitably generating mist having a smaller particle diameter than when a mist nozzle is used, and a bathroom air conditioner equipped with the mist generation system.

  In order to solve the above problems, the present invention takes the following technical means.

  The bathroom mist generating system provided according to the first aspect of the present invention is arranged in the upper or upper part of the bathroom, and is capable of misting hot water supplied through a piping member and ejecting it into the bathroom. A bathroom mist generating system comprising a plurality of mist nozzles, further comprising a rotor-type mist generator disposed above or above the bathroom, and a mist jet from the rotor-type mist generator And the mist ejection from the mist nozzle can be switched, and the rotor type mist generating device is capable of scattering hot water supplied from outside the mist generating device to the surroundings, A plurality of collision walls arranged around the rotor and arranged at a distance from each other and for colliding hot water splashed from the rotor. And at least a part of the gaps between the plurality of collision wall portions is a mist jet opening opened substantially horizontally or downward, and mist generated when hot water collides with the plurality of collision wall portions. Is characterized in that it can be directly ejected from the mist ejection port into the bathroom.

  According to such a configuration, the following effects can be obtained.

  First, by using a mist nozzle and a rotor-type mist generator, mists having different particle sizes can be appropriately generated. In a rotor-type mist generator, the rotational speed of the rotor is increased, and the speed at which hot water collides with a plurality of collision walls is increased so that the mist nozzle has a small particle size that is difficult to generate with a mist nozzle. Mist can be easily generated. Therefore, satisfaction can be given to a user who desires a mist having a very small particle size.

  Second, mist generated by hot water colliding with a plurality of collision walls of the rotor type mist generator passes through a mist outlet as an opening of a gap between the plurality of collision walls in the bathroom. Is directly erupted. Therefore, the fact that most of the mist generated in the mist generating device becomes water droplets before being ejected into the bathroom is eliminated, and the amount of mist ejected into the bathroom can be increased.

  In a preferred embodiment of the present invention, there is provided operation means capable of selecting a mist sauna mode in which a bather takes a hot water mist shower while heating the inside of the bathroom, and using the operation means, the mist is provided. When the sauna mode is selected, in a state where mist ejection from the mist generating device is stopped, an operation of ejecting hot water mist from the mist nozzle is performed, and thereafter at least the temperature and humidity in the bathroom When one rises to a predetermined value, the mist ejection from the mist nozzle is stopped, while the ejection of hot water mist from the mist generating device is started.

  According to such a configuration, in the initial stage when the mist sauna mode is executed, the bathroom is heated using the mist ejected from the mist nozzle, but the mist has a large particle size. In addition, the heat capacity is large and the temperature is not easily lowered. Therefore, in the initial stage of the mist sauna, it is possible to appropriately prevent a problem that the bather takes a cold mist having a lowered temperature. In addition, according to the above configuration, after the bathroom has been heated appropriately, the ejection of the mist having a large particle size is stopped and the mist having a small particle size is ejected from the mist generating device. A refreshing feeling can be enhanced.

  In a preferred embodiment of the present invention, the pipe member includes a branch pipe section that allows hot water to be supplied from the pipe member to the mist generator, and hot water supply to each of the mist nozzle and the mist generator. One or a plurality of valves that can be switched on and off are provided.

  According to such a structure, the mist ejection from a mist nozzle and the mist ejection from a mist generator can be switched appropriately using a simple piping structure.

  In a preferred embodiment of the present invention, when hot water mist is ejected from the mist nozzle, hot water is supplied from the piping member to the mist generating device before the hot water mist is ejected, and An initial water discharge operation in which hot water is jetted as mist from the mist generator into the bathroom is configured to be executed in advance.

  According to such a configuration, it is possible to prevent low temperature mist from being ejected from the mist nozzle. That is, at the initial stage when the supply of hot water to the piping member is started from the outside, a relatively low temperature hot water that is insufficiently heated may be supplied to the piping member. In addition, before the mist is ejected from the mist nozzle, low-temperature hot water may remain in the piping member. It is not preferable that such low-temperature hot water is ejected vigorously from the mist nozzle into the bathroom. On the other hand, according to the said structure, the low temperature hot water which exists in a piping member is made into mist by being sent to a mist generator, and it can be made not to be ejected from a mist nozzle. . Further, according to the above configuration, although there is a possibility that a low temperature mist may be ejected from the mist generating device, the particle size of the mist is small, and the ejection is not so vigorous. It is possible to prevent a great discomfort.

  In a preferred embodiment of the present invention, when the initial water discharge operation is being performed, when hot water is fed into the piping member from the outside, the hot water temperature in the piping member becomes equal to or higher than a predetermined level. Or when the hot water supply amount or hot water supply time from the piping member to the mist generating device exceeds a predetermined value, the hot water supply to the mist generating device is stopped and the hot water supply to the mist nozzle is started. It is comprised so that.

  According to such a configuration, it becomes possible to end the initial water discharge operation early at an appropriate time, and the hot water mist is ejected from the mist nozzle while preventing a large amount of hot water from being supplied unnecessarily to the mist generator. Can be started at an appropriate timing.

  In preferable embodiment of this invention, for the main plugs which can switch on / off of the hot water supply from the exterior into the said piping member in the upstream from the branch connection location of the said branch piping part among the said piping members. When an on-off valve is provided to stop mist ejection from the mist nozzle and the mist generating device, the main plug on-off valve in the pipe member is downstream of the main plug on-off valve in a closed state. The hot water remaining in the mist is supplied to the mist generator, and is ejected from the mist generator into the bathroom as mist.

  According to such a configuration, it is possible to suitably prevent hot water from remaining in the piping member after the mist ejection ends, and to make the hot water flowing in the piping member and the piping member hygienic. Can do. Further, since a mist generator is used as a means for preventing hot water from remaining in the piping member, there is no need to separately provide a draining piping section.

The bathroom air conditioner provided by the second aspect of the present invention is a bathroom air conditioner that is used by being attached to the ceiling or side wall of the bathroom, and for the bathroom provided by the first aspect of the present invention. It is equipped with a mist generating system.
The bathroom air conditioner can be configured such that, for example, the bathroom air can be heated by a heating means such as a heat exchanger and then blown out from the blower opening into the bathroom by a fan.
Preferably, the mist nozzle and the mist generating device are provided in an arrangement in which mist can be ejected in a region where air is blown from a blower port of a bathroom air conditioner or in the vicinity thereof.

  According to such a configuration, the same effect as described for the bathroom mist generating system provided by the first aspect of the present invention can be obtained. In addition, if the bathroom air-conditioning apparatus is provided with a bathroom mist generating system, construction work when the system is installed in the bathroom can be facilitated.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

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

  FIGS. 1-6 has shown an example of the bathroom air conditioner provided with the mist generating system for bathrooms to which this invention was applied, and the structure relevant to this. The bathroom air conditioner A shown in FIG. 1 is configured as a bathroom heating / drying apparatus having a mist generating function, and is attached to a ceiling 80 of a bathroom 8 such as a unit bath having a bathtub 81. The panel 41 provided at the lower part of the bathroom air conditioner A is provided with a mist nozzle 6 and a rotor type mist generating device MG. The mist nozzle 6 and the mist generating device MG are used for the bathroom mist. A generation system SY is configured.

  As shown in FIG. 2, the bathroom air conditioner A includes a case 4, a fan 50, a heat exchanger 51 as a heating unit, and a control unit 7. The case 4 has a lower opening shape that houses the fan 50 and the heat exchanger 51 and is installed on the upper surface side of the ceiling plate 80 of the bathroom. The lower opening of the case 4 is blocked by the panel 41. ing. The panel 41 is provided with an air supply port 41a and a louver 42 having a blower port 41b.

  In the bathroom air conditioner A, when the fan 50 is driven, air is sucked into the case 4 from the air supply port 41 a, and this air is heated by the heat exchanger 51. The heat exchanger 51 is configured using, for example, a plurality of finned tubes to which hot water is supplied from a heat source device 91 such as a hot water supply device installed outside the bathroom 8 via a pipe portion (not shown). The intake air from the fan 50 is heated when passing between the plurality of finned tubes. The heated air is guided to the louver 42 and blown out from the air blowing port 41b. The louver 42 can swing in the direction indicated by the arrow N1, and can be fixed at a desired angle in the swing direction. The flow of air blown out from the blower port 41b can be used to efficiently supply the mist blown from the mist nozzle 6 or the mist generating device MG to a desired region.

  The mist nozzle 6 is located in the vicinity of the air blowing port 41b and is attached to the panel 41 so as to eject mist downward. Of course, the mist nozzle 6 can be configured such that its direction can be changed to a direction desired by the user, such as obliquely below. Further, in the drawing, only one mist nozzle 6 is provided, but a configuration in which a plurality of mist nozzles 6 are provided may be employed. The structure of the mist nozzle 6 can be the same as that conventionally known. For example, when hot water is supplied, a swirling flow of the hot water is generated inside the mist nozzle 6, and this is the same as that of the mist nozzle 6. It is a structure sprayed from the tip opening.

  The mist nozzle 6 is connected to a piping member 60 connected to the heat source unit 91 by piping, and selectively supplies either hot water heated by the heat source unit 91 or non-heated water to the mist nozzle 6. Is possible. The piping member 60 is used to turn on / off the hot water supply to the mist nozzle 6 and the mist generating device MG, and the branch piping portion 60a that can supply the hot water in the piping member 60 to the mist generating device MG. Open / close valves V1 and V2 are provided. In addition, a main plug opening / closing valve V3 is provided in the piping member 60 at a position upstream of the branch connection portion of the branch pipe portion 60a. An air vent valve V4 is also provided on the downstream side of the main plug opening and closing valve V3.

  The mist generating device MG can generate a mist having a finer particle diameter than the mist generated by the mist nozzle 6, and is disposed in the vicinity of the mist nozzle 6. As shown in FIG. 3, the mist generator MG includes a casing 1, a rotor 2 accommodated in the casing 1, and a motor M for rotating the rotor 2.

  The casing 1 has a cup shape with an upper portion opened, and is attached to the lower surface portion of the panel 41 using a plurality of screw holes 10 provided in the upper portion and screw bodies 90 screwed into these. The casing 1 is provided with a plurality of collision wall portions 12 and a plurality of mist jets 13, and the bottom portion of the casing 1 is a water storage portion 14 capable of storing an appropriate amount of hot water. (See also FIG. 5). The branch piping part 60a is provided so that hot water can be supplied to the water storage part 14.

  The rotor 2 is supported by the drive shaft 30 of the motor M and accommodated in the casing 1, and includes a disk-shaped rotating plate 20 and a shaft shape for pumping hot water that protrudes downward from the center of the rotating plate 20. Part 21. The shaft-like portion 21 has a conical shape or a truncated cone shape having a larger diameter toward the upper part. When the shaft-shaped portion 21 has such a shape, when the shaft-shaped portion 21 is rotated at a high speed, the hot water stored in the water storage portion 14 is film-shaped along the outer peripheral surface of the shaft-shaped portion 21. It is possible to generate a lifting force. When the hot water rises along the shaft-like portion 21 and is pumped up to the lower surface of the rotating plate 20, this water is accelerated from the region near the center of the rotating plate 20 toward the outer periphery by centrifugal force, and the rotating plate 20 Spatter around. The action of the rotor 2 is the same as that of the negative ion generator described in Patent Document 3 described above.

  The lower portion of the shaft-like portion 21 is inserted through a drainage hole 16 provided at the bottom of the casing 1. A gap of about 1 to 3 mm, for example, is formed between the drain hole 16 and the outer peripheral surface of the shaft 21. The water present in the gap is always pumped upward by the above-described force (the force that raises the water along the outer peripheral surface of the shaft-like portion 21). As a result, the hot water in the water storage portion 14 leaks downward from the hole portion 16. There is no. Of course, when the rotation of the rotor 2 is stopped, the hot water in the water storage section 14 leaks out of the casing 1 from the hole 16. If the hole 16 is provided, when the operation of the mist generator MG is stopped, for example, when shower water is applied to the casing 1 and this shower water enters the casing 1, this water is supplied from the hole 16 to the casing 1. Can be discharged outside. Therefore, drying in the casing 1 is promoted, which is preferable for maintaining a hygienic state.

  The plurality of collision wall portions 12 are portions for causing the water to collide when the rotor 2 rotates and water is scattered from the rotating plate 20 to the periphery thereof, and a mist having a small diameter is appropriately generated by the collision. It is possible. As shown in FIG. 4, the plurality of collision wall portions 12 are in the form of ribs arranged radially at substantially equal intervals around the central axis of the casing 1. A gap between the collision wall portions 12 adjacent to each other opens toward the inside of the bathroom 8 so as to face in the horizontal direction and downward, and this opening portion is the mist outlet 13. Mist generated when water collides with the plurality of collision wall portions 12 passes through the plurality of mist outlets 13 as they are from the gaps between the plurality of collision wall portions 12 and is directly ejected around the casing 1. It has become.

  As shown in FIGS. 3 and 6, a cylindrical portion 15 a erected upward is provided at the bottom of the casing 1 or in the vicinity thereof, and external air is introduced into the casing 1 from the hole 15 of the cylindrical portion 15 a. Can flow in. When the rotor 2 rotates at high speed, the surrounding air tends to be turbulent, but this turbulent flow disturbs the operation of generating mist and causes variation in the mist particle size. On the other hand, according to the configuration described above, the turbulent flow can be suppressed by supplying external air into the casing 1. The motor M is mounted on the panel 41 using appropriate members 31 and 32. Preferably, an air inflow path for allowing external air to flow into the casing 1 also at the mounting portion of the motor M. Is formed. If such an air inflow path is formed, external air is also supplied to the upper region of the rotor 2, so that turbulence can be more unlikely to occur around the rotor 2.

  In FIG. 2, the control unit 7 of the bathroom air conditioner A is configured using, for example, a microcomputer, and performs operation control of each part of the bathroom mist generation system SY in response to an operation command from the operation remote controller 70. To do. However, in the present embodiment, the control unit 7 and the operation remote controller 70 are also used for controlling the bathroom heating using the fan 50 and the heat exchanger 51 of the bathroom air conditioner A. The operation remote controller 70 can transmit data to the control unit 7 by transmitting infrared rays to an infrared light receiving unit (not shown) of the bathroom air conditioner A, for example, for switching on / off of mist ejection. An operation and an operation for selecting the type of mist to be ejected (coarse mist, fine mist) are possible. Further, as the mist ejection mode, a mist sauna mode in which a bather takes a hot water mist shower while heating the inside of the bathroom 8 can be selected.

  A sensor Sa for detecting hot and cold water temperature is provided in the vicinity of a portion of the piping member 60 where the branch piping portion 60a is branched and connected. A sensor Sb for detecting the temperature and humidity of the intake air is provided in the vicinity of the air supply port 41a. The control unit 7 executes open / close control of the open / close valves V1 to V3, drive control of the motor M, and the like based on signals from the sensors Sa and Sb, a signal from the operation remote controller 70, and the like. However, the specific content will be described later.

  Next, the operation of the bathroom air conditioner A will be described.

  First, the basic operation of the bathroom air conditioner A will be described. In this bathroom air conditioner A, by operating the operation remote controller 70, it is possible to selectively eject coarse mist having a large particle diameter and fine mist having a very small particle diameter. More specifically, when coarse mist is selected, the on-off valves V1 and V3 are open, the on-off valve V2 is closed, and mist is ejected from the mist nozzle 6. The mist ejected from the mist nozzle 6 has a relatively large particle size, as in the description of the prior art described above. On the other hand, when the fine mist is selected, the opening and closing valve V1 is closed, the opening and closing valves V2 and V3 are opened, and the motor M is turned on. Is made. As described above, the mist generating device MG is a system that generates hot water and water splashed from the rotating plate 20 of the rotor 2 by colliding with the plurality of collision walls 12, so that the rotational speed of the rotor 2 is increased. By increasing the collision speed of the hot water with respect to each collision wall portion 12, it is possible to suitably generate a mist having a minute particle size that is difficult with the mist nozzle 6. Therefore, the user can appropriately eject both the coarse mist and the fine mist according to his / her preference and the like, and the user-friendliness can be improved. Of course, in the bathroom mist generating system SY of the present embodiment, the mist can be ejected from both the mist nozzle 6 and the mist generating device MG to increase the total amount of mist ejected into the bathroom 8. .

  When mist is generated using the mist generating device MG, when hot water collides with the plurality of collision wall portions 12 from the rotor 2, a lot of mist is generated in the region of the gap between the plurality of collision wall portions 12. The mist passes through the mist outlet 13 as it is and is jetted into the bathroom 8 (see FIG. 4). Therefore, most of the mist generated in the periphery of the plurality of collision walls 12 is efficiently ejected into the bathroom 8. It is possible to suppress the phenomenon that water droplets are formed in the casing 1 without much of the mist generated in the casing 1 being jetted into the bathroom 8. For this reason, when the mist generating device MG is operated alone, it is possible to suitably avoid that the amount of mist ejected is insufficient, such as taking a mist shower or a mist sauna mode described later. It will be suitable for executing.

  In the bathroom air conditioner A, a mist sauna mode can also be executed. Prior to the details of the mist sauna mode, the outline thereof will be described. Under this mode, first, hot air blowing from the air blowing port 41b and hot water mist from the mist nozzle 6 are carried out, and the bathroom 8 is quickly To be heated. Next, when the bathroom 8 reaches a predetermined temperature or humidity, instead of the mist jet from the mist nozzle 6, hot water mist is jetted from the mist generator MG, and the mist sauna mode is continued.

  More specifically, the mist sauna mode described above is executed by an operation process of the control unit 7 as shown in FIG.

  First, when the mist sauna mode is selected using the operation remote controller 70, the control unit 7 drives the fan 50 and the heat exchanger 51 to start blowing hot air from the air blowing port 41 b, and the mist nozzle 6. Starts the ejection of hot water mist (S1: YES, S2, S3). This hot water mist is ejected by opening the on-off valves V1 and V3 while keeping the on-off valve V2 in the closed state. In this case, hot water having a predetermined temperature is supplied from the heat source device 91 into the piping member 60. According to the operation process described above, in the initial stage of heating, hot water mist having a large particle size and a large heat capacity is ejected from the mist nozzle 6 into the bathroom 8, so that a cold feel is felt when the mist contacts the bather. It is possible to quickly heat the bathroom 8 without giving it. That is, unlike this embodiment, in the early stage of heating when the temperature of the bathroom 8 is low, if a hot water mist having a small particle size and a small heat capacity is ejected, this mist is likely to cause a temperature drop at an early stage. There is a risk of giving a cold feel to the body. In addition, when the mist reaches the floor surface of the bathroom 8, the temperature of the mist is likely to be lowered, so that the floor surface or the like is easily felt cold. On the other hand, according to this embodiment, such a fear can be eliminated appropriately.

  Next, the bathroom 8 is heated to some extent, and when the temperature and humidity of the bathroom 8 become equal to or higher than a predetermined value and this is detected via the sensor Sb, the control unit 7 causes the mist generation from the mist generator MG. Start (S4: YES, S5). This mist ejection is performed by driving the motor M and opening the on-off valve V2. Accordingly, the control unit 7 closes the opening / closing valve V1 and terminates the mist ejection from the mist nozzle 6 (S6). By such a thing, the mist ejected in the bathroom 8 becomes only a mist with a small particle size, and it can be set as a comfortable atmosphere for a bather. As described above, since the mist generated by the mist generator MG has a very small particle size and can increase the amount of spray into the bathroom 8, a comfortable mist sauna bath is possible. Become.

  Thereafter, when an operation to end the mist sauna mode is performed using the operation remote controller 70 (S7: YES), the control unit 7 ends the blowing of hot air from the air blowing port 41b (S8). ). Moreover, the mist ejection from the mist generator MG is also terminated (S9). The mist ejection is terminated by stopping the motor M and closing the open / close valve V2. However, before the motor M is stopped or the opening / closing valve V2 is closed, the main plug opening / closing valve V3 is closed in advance so that the hot water existing in the piping member 60 on the downstream side of the main plug opening / closing valve V3 is removed. The mist may be generated by the mist generator MG and discharged into the bathroom 8. In this way, hot water can be prevented from remaining in the piping member 60.

  The control unit 7 is configured to also perform operation control as shown in FIGS. 8 and 9 when the mist nozzle 6 is turned on / off from the mist nozzle 6.

  First, when an operation to eject coarse hot water mist is performed using the operation remote controller 70, the control unit 7 does not immediately eject mist from the mist nozzle 6, but prior to this, the initial water discharge operation is performed. (S11: YES, S12). This initial water discharge operation is executed by driving the motor M of the mist generator MG with the open / close valves V2 and V3 opened while the open / close valve V1 is closed. According to this initial water discharge operation, the hot water remaining in the piping member 60 or the initial hot water newly supplied from the heat source unit 91 toward the piping member 60 (this initial hot water is a relatively low temperature). Is supplied to the mist generating device MG, and becomes a mist having a small particle diameter and is ejected into the bathroom 8. Therefore, it is avoided that the relatively low temperature hot water is ejected from the mist nozzle 6 into the bathroom 8 and is bathed by the bather. Although a mist of relatively low temperature is ejected from the mist generator MG, the mist has a small particle size and the momentum of ejection is relatively weak, so this mist may cause great discomfort to the bather. Is small.

  Thereafter, when hot water appropriately heated is sent from the heat source device 91 into the piping member 60, the temperature detected by the sensor Sa becomes equal to or higher than a predetermined temperature (S13: YES). Then, the control part 7 makes the on-off valve V1 open, and ejects mist from the mist nozzle 6 (S14). If the mist is ejected from the mist nozzle 6 at such timing, the warm water mist having a large particle size is heated in the bathroom 8 at a relatively early timing while almost no low temperature mist is ejected from the mist nozzle 6. Can be supplied appropriately. Note that the timing at which the mist is ejected from the mist nozzle 6 is, for example, the amount of hot water supplied from the piping member 60 to the mist generator MG or the time when the hot water temperature detected using the sensor Sa becomes a predetermined value or more. The hot water supply time can also be a point in time when the predetermined value is reached.

  When starting the mist ejection from the mist nozzle 6, the control unit 7 closes the open / close valve V2 and stops the hot water supply to the mist generator MG (S15). However, the motor M of the mist generator MG is still driven without being immediately stopped. The reason is that even if the on-off valve V2 is closed, hot water still remains in the branch pipe 60a and in the water storage part 14 of the casing 1, and it is preferable to consume this as a mist. is there. For the motor M, the drive current of the motor M is detected by the control unit 7, and the water level in the water storage unit 14 decreases to reduce the torque of the motor M for driving and rotating the rotor 2. What is necessary is just to stop this motor M when a value becomes below a predetermined value (S16: YES, S17). Of course, instead of this, the motor M may be stopped by a timer setting or the like.

  The above-described operation control shown in FIG. 8 can be applied to any case when the hot water mist is ejected from the mist nozzle 6. Therefore, when performing step S3 of the mist sauna mode shown in FIG. 7, it is possible to perform the operation control shown in FIG.

  When the operation control shown in FIG. 8 is executed and the hot water mist is ejected from the mist nozzle 6, an operation for terminating the mist ejection is performed using the operation remote controller 70 (step S18 in FIG. 9). : YES), the controller 7 closes the on-off valves V1 and V3 and immediately terminates the mist ejection from the mist nozzle 6 (S19). However, the controller 7 opens the open / close valve V2 accordingly, and drives the motor M of the mist generator MG (S20). As a result, the hot water present downstream of the main plug opening / closing valve V <b> 3 and the hot water present in the water storage section 14 of the casing 1 are misted by the mist generator MG and consumed. In addition, it is possible to prevent hot water from remaining in the water reservoir 14. The motor M may be stopped when the hot water storage amount in the water storage section 14 is reduced and the driving current of the motor M becomes equal to or less than a predetermined value, similarly to steps S16 and S17 described above ( S21: YES, S22).

  10 and 11 show another embodiment of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the embodiment shown in FIG. 10, a drain hole is not provided in the bottom portion of the casing 1, and the lower end portion of the shaft-like portion 21 of the rotor 2 does not penetrate the bottom portion of the casing 1. Even with such a configuration, it is possible to obtain the intended effect of the present invention.

  In the embodiment shown in FIG. 11, the shaft-like portion 21 of the rotor 2 has a hole 210. In this embodiment, when the rotor 2 rotates, the water located in the hole 210 of the shaft-like part 21 out of the water in the water storage part 14 is in a film form along the inner peripheral surface of the hole 210 by centrifugal force. And then reaches the upper surface of the rotating plate 20. Next, the water is accelerated by centrifugal force on the upper surface of the rotating plate 20 to form a film, and scatters around the rotating plate 20. Therefore, a rotor provided with the shaft-like portion 21 having such a configuration can also be used.

  The present invention is not limited to the embodiment described above. The concrete structure of each part of the bathroom mist generating system according to the present invention and the bathroom air conditioner equipped with the system can be changed in various ways.

  For example, as the rotor of the mist generating device, it is also possible to employ a rotor in which water is directly supplied on its upper surface using a water supply pipe or the like, and this water is directly scattered around the rotor by centrifugal force. The plurality of collision wall portions do not necessarily have a rib shape with a constant thickness. For example, the thickness may be non-uniform, and the gap between the plurality of collision wall portions may be formed so as to be wider or narrower as the portion approaches the mist ejection port. In addition, from the viewpoint of increasing the amount of mist ejection, it is preferable to provide the plurality of collision walls and mist ejection ports over the entire circumference of the rotor, but do not provide them in some areas. The mist can be prevented from being ejected from the portion. For example, when the mist generating device is disposed in the vicinity of the side wall of the bathroom, it is preferable that a large amount of mist is not applied to the side wall. In such a case, mist is not ejected toward the side wall. Thus, it can be set as the structure which does not provide a mist jet nozzle in the location which faces the said side wall.

  The mist nozzle and the mist generating device of the bathroom mist generating system according to the present invention are attached to a location close to the ceiling portion of the side wall of the bathroom, for example, instead of the ceiling-mounted bathroom air conditioner as in the above-described embodiment. It can also be set as the structure attached to the wall-hanging type bathroom air conditioner. Also, unlike this, the bathroom mist generation system is installed above or above the bathroom using devices / equipment other than the bathroom air conditioner or an appropriate member such as a bracket. Regardless, it may be used alone. The mist nozzle and the mist generating device may be separately attached to separate devices / devices or members separated from each other.

  A plurality of mist nozzles can be used as the mist nozzle. In this case, the roughness of the mist ejected from each of the plurality of mist nozzles may be the same or non-identical. The bathroom mist generating system according to the present invention can be used not only to eject hot water mist but also to eject unheated water mist. Since such a mist is relatively low in temperature, it is suitable for obtaining a refreshing feeling in summer and the like. The bathroom referred to in the present invention is a concept including a bathroom for a sauna bath in which a bathtub is not installed, a shower room, and the like in addition to a general bathroom in which a bathtub is installed.
