Description

  The present invention relates to a mist generating device of a type that makes a liquid mist using a rotating rotor, a mist generating unit having the same, and a bathroom air conditioning system having a mist generating function.

  Specific examples of the mist generating device using a rotor include those described in Patent Documents 1 and 2. Each of the mist generating devices described in these documents has a configuration in which a rotatable rotor is accommodated in a housing, and liquid supplied to the housing or toward the rotor is removed by the rotor. It is configured to scatter around. A collision wall is provided around the rotor, and mist is generated when the liquid collides with the collision wall.

  However, in the prior art, there are points to be improved as described below.

  That is, in the mist generating device of Patent Document 1, the mist generated in the housing is not immediately ejected outside the device, but passes through a predetermined flow path separately formed in the housing and then Spouts outside. For this reason, most of the mist comes into contact with the wall surface of the housing before it is ejected to the outside of the apparatus to form water droplets. Therefore, the amount of mist ejected is small and it is not suitable for applications where it is desired to increase the amount of mist.

  On the other hand, in Patent Document 2, the mist generated in the housing is immediately ejected toward the upper part of the housing. Compared with Patent Document 1, the amount of mist ejected can be increased. However, in this Patent Document 2, since the mist blowing direction is a direction against gravity, the mist is raised to a high position in the bathroom in a state where the mist generating device described in the document is installed on the floor of the bathroom, for example. It is difficult to efficiently supply a large amount of mist to the entire bathroom or a certain area. The inventors have installed a mist generating device on or near the ceiling of the bathroom as a measure to improve such a problem, and then sprayed the mist generated by the mist generating device directly into the bathroom and then downward. Inspired to make progress. However, since the mist generating device blows out toward the upper side of the housing as described above, simply installing this device on the upper part of the bathroom does not efficiently supply the mist to the lower area of the bathroom. Have difficulty. Further, when there is a bathroom side wall in the vicinity of the mist generating device, for example, a lot of mist comes into contact with the side wall to form water droplets, and there is a problem that a large amount of water droplets drips from this portion.

JP 2001-289470 A JP-A-8-182727

  The present invention has been conceived under the circumstances as described above, and increases the amount of mist ejection and appropriately suppresses the mist from being ejected to a region where mist ejection is not preferable. Provided is a mist generating device suitable for installation and use above a bathroom or other desired mist supply target area, a mist generating unit including the same, and a bathroom air conditioning system having a mist generating function That is the issue.

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

The mist generator provided by the 1st side of the present invention is arranged in the housing so that rotation is possible, and the rotor which can supply the liquid supplied in the housing to the circumference can be carried out. A plurality of collision wall portions that are positioned around the rotor and arranged in the circumferential direction of the rotor at an interval, and for generating mist by colliding liquid splashed from the rotor, The gap between the plurality of collision wall portions is a mist ejection port that opens toward the periphery of the housing, and the opening portion ejects mist around the housing, A part of the periphery of the plurality of collision walls is shielded from the mist ejected from the mist ejection port or blocked by the mist ejection port. Mist blocking wall to prevent the mist is ejected are provided on the parts, as the side portion of the housing, standing in the vertical height direction of the housing, and so as to intersect at substantially right angles in plan view A pair of side surfaces connected to each other is provided, and the mist blocking wall is provided to prevent the mist from being ejected to the outside of the housing from the region where the pair of side surfaces are formed. It is characterized by being.

According to such a configuration, when liquid splattered from the rotor collides with a plurality of collision wall portions and mist is generated, the mist directly serves as a mist outlet as an opening of a gap between the plurality of collision wall portions. It passes and is ejected around the housing. Therefore, unlike the prior art, the mist generated in the housing is passed through a separately formed path and then ejected to the outside of the housing to reduce the chance that the generated mist is formed into droplets, and to the outside of the housing. The amount of mist ejected can be increased. In the present invention, a part of the mist is prevented from being ejected to the outside of the housing by the mist shielding wall, but even in the case where the ejection of the part of the mist is prevented in this way, in the region other than the mist shielding wall, As a result of preventing the mist from being formed into droplets, it is possible to increase the amount of mist ejected to the outside of the housing. When the mist generating device of the present invention is installed above the mist supply target area, most of the mist ejected around the housing can be lowered toward the mist supply target area and efficiently supplied. . Accordingly, it is possible to appropriately realize that the mist supply target area is filled with many mists. On the other hand, according to the present invention, mist can be prevented from being ejected to the outer region of the mist blocking wall in the periphery of the housing. Therefore, when the mist generating device is installed near an area where it is not preferable to spray mist, the mist blocking wall is set so as to face the above-mentioned area.
Furthermore, according to the said structure, with respect to desired corner parts, such as a bathroom and the exterior case mentioned later (corner part where two surfaces crossed substantially right angle), a mist generating apparatus is in a space efficient and good-looking state. Can be installed. That is, when the pair of side surfaces intersecting at a substantially right angle of the housing face the two surfaces of the corner portion, the housing can be installed with good appearance without generating a large gap in the corner portion. Further, in such an installation state, it is possible to prevent many mists from being sprayed on the two side surfaces of the corner portion.

  In a preferred embodiment of the present invention, the mist blocking wall is provided in an arrangement spaced from the plurality of collision wall portions so as not to block the mist ejection port, and all of the plurality of collision wall portions. Alternatively, a part of the housing is spaced apart from the top or bottom of the housing in the vertical height direction of the housing, so that there is a space between the region where the plurality of collision walls are arranged and the top or bottom of the housing. An air outflow opening is formed to allow air around the rotor to flow out to the vicinity of the periphery of the plurality of collision walls when the rotor rotates.

  Although details will be described later with reference to FIG. 8, according to the above configuration, when the rotor rotates, a unique air flow is generated between the plurality of collision wall portions and the mist blocking wall. It is possible to suppress the occurrence of bias in the mist amount distribution when the mist is ejected by the action of air flowing through the air outlet opening. Also, as will be described later with reference to FIG. 8, effects such as suppression of wind noise when the rotor rotates at high speed and excellent quietness, and stabilization of mist generation and ejection can be obtained. .

  The mist generating unit provided by the second aspect of the present invention includes a mist generating device provided by the first aspect of the present invention, the housing of the mist generating apparatus, the rotor, and the driving of the rotor. A mist opening for allowing the mist sprayed around the housing from the mist outlet to directly travel to the outside of the exterior case. The mist blocking wall is provided so as to suppress the mist from being ejected toward a region other than the opening of the exterior case.

  According to such a configuration, since the housing of the mist generating device, the motor for driving the rotor, and the like are covered by the outer case, the overall appearance can be improved and the protection thereof can be achieved. Furthermore, according to the said structure, it is also avoided appropriately that many mists are sprayed toward an exterior case and it becomes a droplet.

  In a preferred embodiment of the present invention, the exterior case has a plurality of wall portions that stand in the vertical height direction of the housing and surround the periphery of the housing, and the plurality of wall portions include the mist. There are a front wall portion in which an opening for use is formed, and first and second side wall portions in which the opening for mist is not formed and one end side is connected to both end edges of the front wall portion. The other end sides of the first and second side wall portions are connected so as to intersect at a substantially right angle in plan view.

  According to such a configuration, for example, in a corner portion of a bathroom, a mist generating unit is installed in a space-efficient and good-looking state on a corner portion formed by intersecting two wall surfaces at a substantially right angle. It becomes possible to do. That is, if the first and second side wall portions of the outer case are set so as to face the two wall surfaces of the corner portion, the outer case and thus the mist are generated so that no large gap is generated in the corner portion. The unit can be installed in a style. Further, in such an installation state, it is possible to prevent a large amount of mist from being sprayed on the two wall surfaces of the corner portion.

  In a preferred embodiment of the present invention, each of the first and second side wall portions is provided with an opening that can be used for both insertion of the piping member and insertion of the electrical wiring, The drawing of the piping member for supplying the liquid into the outer case and the drawing of the electric wiring for the motor can be performed from either side of the first and second side wall portions. Yes.

  According to such a configuration, when the piping member for supplying the liquid and the electric wiring for the motor are drawn from the outside to the inside of the exterior case, the flexibility of the drawing operation is excellent. In addition, when the exterior case is installed in a corner of a bathroom or the like, if piping members and electrical wiring are drawn into the exterior case from the two wall surfaces of the corner, these are unnatural on the front of the exterior case. It is also possible not to be arranged with.

  In a preferred embodiment of the present invention, the exterior case has a plurality of wall portions that stand in the vertical height direction of the housing and surround the periphery of the housing, and the plurality of wall portions include the mist. There are provided a rear wall portion in which the opening for use is not formed, and a front wall portion that projects in front of the rear wall portion and that is formed by extending the mist opening in the circumferential direction.

  According to such a configuration, for example, it is preferable to install and use at a location other than the corner portion of the side wall portion of the bathroom or in the vicinity thereof. In this case, the back wall portion of the exterior case may be made to face the side wall portion of the bathroom, and in this way, a large amount of mist is not ejected toward the side wall portion of the bathroom, while the mist of the exterior case is Mist can be ejected from the opening for a relatively wide range.

  The bathroom air-conditioning system provided with the mist generating function provided by the third aspect of the present invention includes a bathroom air-conditioning apparatus used by being arranged above or above the bathroom, and the bathroom air-conditioning apparatus attached to the bathroom air-conditioning apparatus. Mist generating means for performing mist ejection, and the mist generating means is a mist generating device provided by the first aspect of the present invention or a mist provided by the second aspect of the present invention. The generation unit is used.

  According to such a configuration, the same effect as described for the mist generating device provided by the first aspect of the present invention or the mist generating unit provided by the second aspect of the present invention can be obtained.

  In a preferred embodiment of the present invention, the bathroom air conditioner is attached to a side wall portion of the bathroom, and air can be blown out from the air outlet in a front direction or a front obliquely downward direction of the bathroom air conditioner. The mist generating device or the mist generating unit is attached to an end surface on one end side in the width direction of the case, and is capable of ejecting mist in a substantially same direction as a front direction of the bathroom air conditioner, and an end surface of the bathroom air conditioner And it is set as the structure by which the mist ejection toward the side wall part of the said bathroom was suppressed.

  According to such a configuration, it is appropriate that the mist generating device or the mist generating unit is attached to the so-called wall-mounted bathroom air conditioner in a clean manner and the mist is sprayed onto the end face of the bathroom air conditioner or the side wall of the bathroom. The mist can be efficiently supplied to a certain area in the bathroom by using the flow of air blown out from the air outlet of the bathroom air conditioner.

  In a preferred embodiment of the present invention, the mist outlet of the mist generator or the mist generator unit is arranged at a position higher than the air outlet of the bathroom air conditioner.

  According to such a configuration, in the process in which the mist ejected from the mist ejection port descends due to gravity, the mist can be placed on the air flow blown out from the air blowing port of the bathroom air conditioner. The flow is used to more accurately supply the mist to a certain area.

  In a preferred embodiment of the present invention, there is provided means capable of switching between forward and reverse rotation directions of a motor for driving the rotor of the mist generating device or the mist generating unit.

  When the mist is ejected from the mist generating device, the mist ejection amount distribution is biased, and there is a tendency that a region where the mist amount increases and a region where the mist amount increases are generated (refer to FIGS. 8 to 10 for details). Will be described later). On the other hand, according to the above configuration, since the rotation direction of the rotor can be switched, it is possible to cause the mist to be positively biased and ejected to an area where the mist ejection amount is desired to be increased. .

  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.

  1 to 7 show an example of a mist generating unit including a mist generating device to which the present invention is applied, and a configuration related thereto. 1 to 4, the mist generating unit U1 of the present embodiment has a configuration in which a mist generating device MG1 is accommodated in the exterior case 4. The mist generated by the mist generator MG1 is ejected from the mist opening 40 formed in the exterior case 4 to the outside.

  As clearly shown in FIG. 5, the mist generator MG <b> 1 includes a housing H, a rotor 2, and a motor M for driving the rotor 2.

  The housing H is for housing the rotor 2 therein, and includes a housing body 1 and a substantially flat cover body 10 assembled on the upper side of the housing body 1. Both the housing body 1 and the cover body 10 are made of resin. The upper surface of the bottom portion 11 of the housing body 1 is inclined so as to be lower toward the center portion, and forms a liquid storage portion 14 capable of storing hot water supplied from a water supply pipe 92 described later. . The cover body 10 plays a role of preventing mist from being ejected toward the upper side of the housing H. On the cover body 10, a motor M is mounted via a spacer portion 32 or the like. Yes. An air inflow port 33 is formed in the cover body 10, and external air can flow into the housing H through the air inflow port 33.

  The rotor 2 is supported by the drive shaft 30 of the motor M and accommodated in the housing H, and includes a disc-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 liquid storage portion 14 is filmed along the outer peripheral surface of the shaft-shaped portion 21. It can be raised as a shape. When the hot water rises along the shaft-like portion 21 and is pumped up to the lower surface of the rotating plate 20, the hot 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. Such an action of the rotor 2 itself is the same as the rotor of the apparatus described in Patent Document 1 described above.

  The housing H is provided with a plurality of collision wall portions 12, a plurality of mist ejection ports 13, an air outlet opening 19, and a mist blocking wall 18. 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 minute particle diameter is appropriately generated by the collision. It is possible to make it. The plurality of collision wall portions 12 are provided upright on the housing body 1 so as to surround the periphery of the rotor 2, and as shown in FIG. 7, ribs arranged in a circumferential manner at substantially equal intervals. It is. A gap between the collision wall portions 12 adjacent to each other is opened in a substantially horizontal direction toward the periphery of the housing H, and this opening portion is a mist ejection port 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 ejected around them.

  As shown in FIG. 5, a gap is formed between the upper end of each collision wall portion 12 and the lower surface of the cover body 10, and the region where the plurality of collision wall portions 12 are arranged side by side and the cover body 10 is formed with an air outlet opening 19. This air outflow opening 19 is formed over the entire circumference or substantially the entire circumference above the plurality of collision wall portions 12, and causes an effect of suppressing the occurrence of bias in the mist ejection amount. Details will be described later. Note that the configuration of the air outlet opening 19 may be formed between the plurality of collision wall portions 12 and the upper surface of the housing body 1, unlike the present embodiment. In this case, a plurality of collision wall portions 12 may be provided so as to protrude downward from the cover body 10, and a gap may be formed between the lower ends of the plurality of collision wall portions 12 and the upper surface of the housing body 1.

  The mist blocking wall 18 is a portion for blocking a part of the mist ejected from the plurality of mist ejection ports 13, and is located at a part of the periphery of the plurality of collision wall portions 12. As shown in FIG. 7, the mist blocking wall 18 is configured as a convex portion that is substantially L-shaped in plan view and protrudes upward from the upper surface portion of the housing body 1. When the mist is sprayed onto the mist blocking wall 18, the mist is converted into water droplets, but the water thus generated subsequently flows into the liquid storage unit 14 and is reused for the generation of mist. The cover body 10 is placed on the upper surface portion of the mist blocking wall 18, and the cover body 10 and the housing body 1 are screwed to this portion. According to such a configuration, the mist blocking wall 18 is also used as a mounting base for the cover body 10, and the configuration is reasonable.

  As shown in FIGS. 4 and 6, the side surface of the housing H is formed with a side surface 17 a having a circular arc shape in plan view and a pair of side surfaces 17 b having a substantially planar shape. A part of the side surface portion 17a is opened to allow mist ejection from the mist ejection port 13 to the outside of the housing H. On the other hand, the pair of side surface portions 17b are side surface portions in which mist ejection is prevented by the mist blocking wall 18, and are connected so as to intersect at substantially right angles in a plan view.

  A plurality of ribs 15 c are provided upright on the bottom 11 of the housing H. These ribs 15 c prevent the air around the shaft-shaped portion 21 from becoming turbulent when the rotor 2 rotates, and the hot water in the liquid storage portion 14 is pumped up along the shaft-shaped portion 21. This helps to stabilize the movement that proceeds toward the periphery of the rotating plate 20.

  As shown in FIGS. 1 to 4, the outer case 4 has a box shape assembled using a plurality of resin members. The exterior case 4 has a front wall portion 43 in which a mist opening 40 is formed as a plurality of wall portions erected in the vertical direction, and one end side of each end of the front wall portion 43 is connected to both ends of the front wall portion 43. First and second side wall portions 41 and 42 are provided. The mist opening 40 is located in front of a region where the mist can be ejected around the housing H in the mist generating device MG1, and has a size corresponding to the region. 3 and 4, the other end sides of the first and second side wall portions 41 and 42 are connected so as to intersect at a substantially right angle in plan view. The mist generating device MG1 is housed in the outer case 4 so that the pair of side surface portions 17b of the housing H face the inner surfaces of the first and second side wall portions 41,. According to such a configuration, it is possible to prevent a large dead space from being generated between the pair of side surface portions 17b and the first and second side wall portions 41 and 42. This prevents the size of the exterior case 4 from becoming considerably large compared to the housing H, and is preferable for reducing the overall size. The front wall portion 43 of the exterior case 4 has a shape corresponding to the side surface portion 17 a of the housing H.

  The first and second side wall portions 41 and 42 are provided with openings 44a and 44b. These openings 44a and 44b can be used to insert either the water supply pipe 92 or the electric wiring L for supplying power to the motor M. According to such a configuration, when the water supply pipe 92 and the electric wiring L are drawn into the outer case 4, any one of the openings 44a and 44b may be selected and used. In FIG. 3, the water supply pipe 92 is inserted through the opening 44a and the electric wiring L is inserted through the opening 44b. However, it is also possible to arrange it in the opposite direction. In addition, both the water supply pipe 92 and the electric wiring L can be inserted into only one of the openings 44a and 44b. Since mist is not ejected from the mist generating device MG1 toward the first and second side wall portions 41 and 42, the openings 44a and 44b are provided from this portion, so that the exterior is provided from this portion. Mist does not leak out of the case 4.

  Next, the operation of the mist generating unit U1 will be described. In addition, when using the mist generation | occurrence | production unit U1 for the mist supply use in a bathroom, when it combines with a bathroom air conditioner, a more preferable effect will be acquired, but this point is mentioned later.

  First, the mist generating unit U1 is preferably used by being attached to a corner portion of a bathroom or the like in which two wall portions 95 and 96 intersect at a substantially right angle, as indicated by a virtual line in FIG. In this attachment, the first and second side wall portions 41 and 42 of the outer case 4 are made to face the wall portions 95 and 96. Thus, the mist generating unit U1 can be installed in the corner portion without causing a large dead space in the corner portion. Although not shown in the drawings, the outer case 4 may be fixed to the walls 95 and 96 using screwing means or an appropriate bracket. Since the outer case 4 covers the mist generating device MG1, the overall appearance becomes better. Further, the mist generating device MG1 can be protected by the exterior case 4, and it is possible to prevent troubles in the electric system such as the motor M and its electric wiring L in particular. At the time of construction of the mist generating unit U1, the water supply pipe 92 and the electric wiring L can be inserted into any of the two openings 44a and 44b as described above, and the construction work can be facilitated. .

  In the mist generating device MG1, when water is supplied from the water supply pipe 92 to the liquid storage unit 14 and the rotor 2 is rotated by driving the motor M, a part of the water stored in the liquid storage unit 14 is as described above. In addition, the rotating action of the shaft-like portion 21 of the rotor 2 raises to the lower surface of the rotating plate 20 along the outer peripheral surface of the shaft-like portion 21, and then scatters around it and collides with the plurality of collision wall portions 12. Due to this collision, a large amount of mist is generated in the gaps between the plurality of collision wall portions 12, and this mist passes through the mist outlet 13 as it is. In a place where the mist blocking wall 18 is not provided, the mist is directly discharged to the outside of the outer case 4. If the mist is ejected through such a path, the rate at which the mist forms water droplets in the housing H is very small, and the amount of mist ejected to the outside of the exterior case 4 can be increased. Further, the mist is ejected toward the front direction (substantially horizontal direction) of the mist opening 40. Therefore, if the mist generating unit U1 is disposed, for example, in the upper part of the bathroom, the mist can be efficiently supplied to substantially the entire area or a fixed area of the bathroom by, for example, lowering the mist by gravity. Therefore, when a bather takes a mist shower, for example, many mists can be taken and it becomes comfortable.

  On the other hand, the mist blocking wall 18 appropriately prevents mist from being ejected from the region where the pair of side surface portions 17b of the housing H is formed. For this reason, there is no problem that mist is blown from the pair of side surface portions 17b to the inner surface of the outer case 4 so that many water droplets are generated on the inner surface of the outer case 4. Of course, in the mist generating unit U1 of the present embodiment, it is also possible to prevent a large amount of mist from being sprayed on the two wall portions 95 and 96 shown in FIG. Therefore, a large amount of water droplets are not generated in those portions.

  As will be described below, the mist blocking wall 18 becomes a factor that causes a bias in the distribution of the mist ejection amount. However, such a bias is also alleviated by providing the air outflow opening 19 in the mist generator MG1. In this regard, first, the proportionality shown in FIG. 8B (this proportionality is also included in the present invention) will be described. In this comparison, when the rotor 2 rotates, a high-speed air flow indicated by an arrow N1 swirling in the rotation direction of the rotor 2 is generated around the rotor 2. The air existing between the plurality of collision wall portions 12 and the mist blocking wall 18 is also strongly influenced by the rotation of the rotor 2 and has a flow similar to the air flow indicated by the arrow N1. As a result, an air flow as shown by an arrow N4 is generated between the plurality of collision wall portions 12 and the mist blocking wall 18. When this air flow flows out of the housing H, the peripheral mist is attracted by the negative pressure action in this region, and a phenomenon occurs in which the mist is biased in a partial region indicated by reference numeral n1. On the other hand, in the mist generator MG1, as shown by an arrow N3 in FIG. 5A, the air in the housing H passes through the air outlet opening 19 and the outer periphery of the plurality of collision walls 12 Or it flows out to the vicinity. For this reason, the volume of the air flow indicated by the arrow N4 shown in FIG. As a result, it is possible to alleviate the mist bias that has occurred in proportion.

  In the present invention, unlike the present embodiment, a mist blocking wall is provided so as to close the mist ejection port 13, thereby preventing the mist from being ejected to a certain region around the housing H. is there. With such a configuration, the air flow indicated by the arrow N4 described above, that is, the air flow passing through the gaps between the mist blocking wall 8 and the plurality of collision wall portions 12 in a fixed direction is not generated. However, when such a configuration is adopted, air turbulence is generated in the housing H because the air outflow is not made uniformly from each of the plurality of mist outlets 13 when the rotor 2 rotates, and this is caused by this. Mist generation tends to be unstable. On the other hand, in this embodiment, it becomes a thing preferable for suppressing such a thing.

  As will be described below, the air outflow opening 19 further reduces the wind noise when the mist generator MG1 is operated and further stabilizes the generation of mist. That is, in the comparison of FIG. 8B, a part of the high-speed air flow indicated by the arrow N1 generated when the rotor 2 rotates flows into the gaps between the plurality of collision wall portions 12 as indicated by the arrow N2. To do. As a result, wind noise is generated. On the other hand, in the mist generator MG1 shown in FIG. 5A, the air flow indicated by the arrow N3 is generated as described above, and thus the volume of the air flow indicated by the arrow N2 is reduced. Since the gaps between the plurality of collision walls 12 and the opening 19 communicate with each other, the volume of the air flow indicated by the arrow N2 is more accurately reduced. As a result, the wind noise described above is reduced.

  The plurality of collision wall portions 12 serve as an air flow resistance indicated by an arrow N2. For this reason, in the comparison of FIG. 8B, air turbulence tends to occur in the vicinity of the plurality of collision wall portions 12. Such a turbulent flow makes the generation of mist unstable and causes a large variation in the particle diameter of the mist. On the other hand, in the mist generating device MG1, since the volume of the air flow indicated by the arrow N2 is reduced due to the air flow indicated by the arrow N3, the resistance of each of the collision wall portions 12 with respect to this air flow is reduced. Turbulence is less likely to occur. Therefore, mist can be generated stably and the particle size of the mist can be made uniform.

  FIG. 9 shows an example of a bathroom air conditioning system having a mist generating function to which the present invention is applied. The bathroom air conditioning system S1 of this embodiment includes the mist generating unit U1 and the bathroom air conditioner A described above.

  The bathroom air-conditioning apparatus A is a wall-hanging type that is attached to a side wall 97 standing upright in the bathroom. As the bathroom air conditioner A, a conventionally known one can be used, and the details of the structure are omitted. However, a heat exchanger (not shown) as a fan and heating means is accommodated in the case 80. When the fan is driven, the bathroom air is sucked into the case 80 from the air supply port 81 on the upper surface of the case 80 and heated by the heat exchanger. It is possible to blow out from the blower opening 82 toward the front face or obliquely below the front face.

  The mist generating unit U1 is attached to the end surface 80a on the one end side in the width direction of the bathroom air conditioner A. This attachment is made such that the second side wall 42 of the outer case 4 faces the end face 80a and the first side wall 41 faces the side wall 97 of the bathroom. Since the end surface 80a and the surface of the side wall portion 97 form a corner portion that intersects at a substantially right angle, the outer case 4 can be placed in this portion with good appearance. A part of the mist opening 40 opens in a direction substantially the same as the front direction of the bathroom air conditioner A, and mist can be ejected in the vicinity of the air blowing area from the blower opening 82. In addition, each mist outlet 13 is arranged higher than the air outlet 82 by an appropriate height h1. Therefore, in the mist generating unit U1, mist can be effectively ejected in the vicinity of the air flow region from the air blowing port 82. Such mist is attracted to the air flow region by a negative pressure action, and then efficiently carried to a predetermined region in the bathroom along the air flow.

  The electric wiring L for the motor M is drawn out from the bathroom air conditioner A to the outside, and is drawn into the exterior case 4 through the opening 44b. As a power source for the motor M, for example, a power circuit of a bathroom air conditioner A is used. On the other hand, the water supply pipe 92 is drawn into the exterior case 4 from the back side of the side wall 97 of the bathroom through the opening 44a.

  The bathroom air-conditioning system S1 includes means capable of switching the rotation direction of the motor M between forward and reverse. This means is realized as a changeover switch such as a dip switch attached to a power circuit board in the bathroom air conditioner A, for example. In the present embodiment, the rotation direction of the motor M (also the rotation direction of the rotor 2) is the direction indicated by the arrow N10 in FIG. Contrary to the present embodiment, when the rotation direction of the motor M is the direction indicated by the arrow N11 in FIG. 10, as described with reference to FIG. 8B, the reference numeral n1 ′ in FIG.
