Description

  The present invention is, for example, a mist generating device suitable for a use in which water (including hot water) is sprayed in a mist to obtain a sauna effect, a heating effect, or a shower effect by mist, and a bathroom heating device provided with the same. About.

  Conventionally, as a specific example of a mist generating apparatus that is used by being installed in a bathroom, for example, there is one described in Patent Document 1. In the mist generator described in the same document, a horizontal disk that can be driven and rotated by a motor is provided in a case installed on the floor of a bathroom, and water is provided on the disk from above. When supplied, this water is scattered around the disk by centrifugal force and collides with a plurality of collision wall portions arranged around the disk. By this collision, the water is made into fine water droplets, and mist is generated. The mist passes through an opening formed in the upper surface portion of the case and blows out above the case.

  However, the prior art has a problem to be solved as described below.

  That is, the mist is blown out above the case, but this direction is different from the direction in which water travels from the disk toward the plurality of collision walls by centrifugal force. For this reason, it is difficult to cause many mists to vigorously move upward, and most of the mist generated in the case remains trapped in the case, so that water droplets having a large particle diameter are easily formed in the case. Moreover, the blowing direction of the mist is a direction against gravity, and it is difficult to raise the mist high. For this reason, the amount of mist blown out and the height of the mist are deficient, making it difficult to fill a large amount of mist in, for example, a bathroom or a partial area of the bathroom. Furthermore, in the prior art, since the mist generating device is installed on the floor surface of the bathroom, there is a problem that it is difficult to secure the installation space in the bathroom.

  As a measure for improving the above-described problems, it is conceivable to install the mist generating device on the ceiling of a bathroom or the like and provide a duct for guiding the mist blown upward from the case downward. However, when such a means is used, the entire apparatus becomes large and complicated, and when the mist passes through the duct, the mist is brought into contact with the duct to form water droplets and into the bathroom. Mist supply is considerably reduced. In addition, there is a new problem that water droplets generated in the duct drop into the bathroom.

  Other conventional examples different from the above are described in Patent Documents 2 and 3. However, what is described in Patent Document 2 is a type that is installed on a floor surface and used in a manner similar to that described in Patent Document 1, and is not suitable for bathroom use. Moreover, since the thing described in the said literature 2 is only one mist blowing outlet formed in the surrounding wall part of a case, the mist generated in the location away from this mist blowing outlet is efficiently mist blowing. It is difficult to guide to the mouth and blow out to the outside, and the amount of mist blown out tends to be small. On the other hand, what is described in FIG. 1 of Patent Document 3 is such that the mist generated in the case is jetted out of the case from the opening provided in the side portion of the case. After colliding with this collision wall and occurring around the collision wall, the air passes through a duct-shaped passage by blowing from below and reaches the opening of the case. In this case, most of the mist becomes water droplets before reaching the opening, and the amount of mist blown out is small.

JP-A-8-182727 JP-A-6-269699 Japanese Patent Publication No. 1-101414

  The present invention has been conceived under the circumstances as described above, and includes a mist generator capable of increasing the amount of mist supplied to a desired region with a simple structure, and the same. The problem is to provide a bathroom heating device.

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

  The mist generator provided by the first aspect of the present invention includes a rotor accommodated in a case and capable of scattering supplied water around the rotor by centrifugal force, and a space between the rotor and the rotor. And a plurality of collision walls that are capable of generating mist by colliding water splashed from the rotor, wherein the plurality of collisions A plurality of mist jets that are formed in the peripheral wall portion of the case in communication with the gap between the wall portions, and that allow the mist generated by colliding with the plurality of collision wall portions to be directly jetted around the peripheral wall portion of the case. An outlet and an attachment means for attaching the case to the attachment target part, with the part located above the space part to which the mist is supplied as an attachment target. Said mounting means, the located above the plurality of mist spray port, said plurality of mist spray port is characterized by being capable disposed below the attachment target part.

  According to such a configuration, the mist generated by the collision of water with the plurality of collision wall portions then passes through the gaps between the plurality of collision wall portions and the plurality of mist jets communicating therewith, and the case. Will immediately erupt around the peripheral wall. When water is splashed from the rotor in a substantially horizontal direction and collides with a plurality of collision walls, the mist proceeds in the substantially horizontal direction as it is and is ejected vigorously outside the case. For this reason, in the present invention, the mist generated in the case is less likely to come into contact with the inner surface of the case before passing through the mist ejection port to form water droplets, and the amount of mist ejected to the outside of the case is reduced. Can do a lot. In addition, as an important effect, the mist generating device of the present invention can be used in a space part to which mist is supplied, for example, a ceiling part of a bathroom or a bathroom heating device installed on the ceiling part by using an attachment means. A case can be attached to a portion located above, and mist can be suitably supplied to the space below the case. Since the plurality of mist outlets are positioned below the attachment means, it is also preferable that when the mist ejected from the mist outlet descends, the mist contacts, for example, the attachment means. Avoided. Therefore, a large amount of mist can be efficiently supplied to the lower space portion of the attachment location of the mist generator. Of course, according to the present invention, there is no need for a separate duct for supplying mist downward, and the overall configuration can be simplified. Moreover, since it is not a floor installation type, when installing in a bathroom, the trouble of having difficulty in securing the installation space is also eliminated.

  In a preferred embodiment of the present invention, the lower part of the case is a water storage part capable of storing water, and the rotor extends downward from the rotary plate and part of the water in the water storage part. Has a water pumping part that can be immersed, and when the rotor rotates, the water in the water storage part rises to the rotary plate by the pumping part and scatters from the rotary plate toward the plurality of collision walls. It is configured as follows.

  According to such a structure, the operation | movement which makes water collide with a some collision wall part at high speed can be exactly performed with a simple structure. Moreover, the water supply from the outside should just be performed with respect to a water storage part, and the water supply is also easy. Furthermore, since the lower part of the case is a water storage part, the configuration is rational, and an increase in the number of parts is suitably suppressed.

  In a preferred embodiment of the present invention, a part of the water splashed around the rotor from the periphery thereof that has not been ejected to the outside of the case is configured to return to the water reservoir.

  According to such a configuration, it is not difficult to treat water that has not been ejected outside the case among the water scattered toward the plurality of collision walls. Since the water returned to the water reservoir is used again for mist formation, the amount of water consumption is also suppressed. In addition, if water consumption is suppressed, the amount of water supplied when water is replenished to the reservoir can be reduced, so the piping for supplying water to the reservoir and the small size of its accessories Can also be achieved.

  In a preferred embodiment of the present invention, an inclined surface that is inclined so that the height is lower toward the center axis of the case is formed in the lower portion of the plurality of mist outlets of the inner surface portion of the case. Has been.

  According to such a configuration, the water that has not been ejected to the outside of the case flows along the inclined surface into the water storage section, and the water recovery operation can be performed smoothly.

  In a preferred embodiment of the present invention, a portion of the case that forms the water storage portion has an inner diameter or an inner width that is smaller than a portion where the plurality of mist outlets are provided.

  According to such a configuration, it is possible to reduce the amount of water remaining in the water storage unit when the water storage unit has a small capacity and the operation of the apparatus is stopped. It is desirable to prevent water from remaining in the case when the equipment is shut down. However, if the amount of water in the reservoir is small, it is easy and quick to dry the case by evaporating this water. The

  In a preferred embodiment of the present invention, an air circulation section is provided that allows external air to be supplied from above the upper region of the rotor rotating plate.

  According to such a configuration, the following effects can be obtained. That is, when the rotor rotates at high speed, air turbulence is generated around the rotating plate. This turbulent flow disturbs the operation of water splashing from the outer surface of the rotating plate and colliding with a plurality of collision wall portions, and becomes a factor that generates mist having a large variation in particle diameter. On the other hand, according to the said structure, since external air is supplied to the upper area | region of a rotating plate, the above-mentioned turbulent flow is relieve | moderated. As a result, it is more preferable to make the mist particle size finer and uniform.

  In a preferred embodiment of the present invention, among the cases, the case is provided below the plurality of mist outlets, and external air can be supplied from the lower side to the lower region of the rotating plate of the rotor. An air inlet is provided.

  According to such a configuration, as in the case where external air is supplied to the upper region of the rotating plate, the turbulent flow of air around the rotating plate is mitigated, and the mist particle size is made finer and uniform. It becomes suitable for promoting.

  The bathroom heating device provided with the mist generating device provided by the second aspect of the present invention includes a case installed in the upper part of the bathroom, the air in the bathroom sucked into the case, and the air blower A bathroom heating device comprising: a fan blown out into the bathroom; and heating means capable of heating the air sucked into the case by driving of the fan, provided by the first aspect of the present invention. The mist generator is attached to the bathroom heater so that the plurality of mist outlets are located below the bottom of the case of the bathroom heater. It is characterized by.

  According to such a configuration, an effect similar to that described for the mist generator provided by the first aspect of the present invention can be obtained. Also, the bathroom heating device serves as a bracket for the mist generating device, and the construction work of the mist generating device can be omitted or simplified. Multiple mist outlets of the mist generator are located below the bottom of the case of the bathroom heating device, so that the mist generated by the mist generator falls on the case of the bathroom heating device. Is also preferably avoided.

  In preferable embodiment of this invention, the 1st aspect which guides the mist ejected from these mist ejection openings using the ventilation from the said ventilation opening, and the case of the said mist generating apparatus from the said ventilation opening The second mode of promoting drying of the case by sending heated air can be selectively executed.

  According to such a structure, in the case of the said 1st aspect, mist can be efficiently supplied to the desired area | region of a bathroom using the ventilation from a bathroom heating apparatus. On the other hand, in the case of the second mode, in the state where the operation of the mist generating device is stopped, the evaporation of the water remaining in the case of the mist generating device or the water adhering to the wall surface is promoted. Can be dried early.

  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 4 show an example of a mist generating apparatus to which the present invention is applied and a configuration related thereto. As clearly shown in FIG. 1, the mist generator MG of the present embodiment includes a case 1, a rotor 2, and a motor M.

  The case 1 is made of a synthetic resin, and the overall schematic shape thereof is a cup shape having a circular shape in plan view with an upper portion opened. The case 1 has a plurality of screw holes 10 provided in the upper portion, a plurality of rib-shaped collision wall portions 12, a plurality of mist ejection ports 13, a water storage portion 14, and a plurality of air inlets 15.

  The plurality of screw holes 10 are portions for attaching the case 1 to a desired location, and correspond to an example of attachment means in the present invention. As shown in FIG. 4, the screw holes 10 are provided in the ring-shaped upper portion of the case 1 at, for example, three locations at regular intervals. In this embodiment, the attachment object of case 1 is made into the panel 41 of bathroom heating apparatus H1, H2 mentioned later with reference to FIGS. The case 1 is attached to the panel 41 by bringing the upper surface of the case 1 into contact with the lower surface of the panel 41 and screwing the screw body 90 into the screw hole 10 from above the panel 41.

  The plurality of collision wall portions 12 are portions for causing the water to collide when the rotor 2 rotates and water splashes from the rotor 2 to the outer periphery thereof. As shown in FIGS. The ribs are arranged radially at substantially equal intervals around the central axis. Each collision wall portion 12 has a uniform thickness and extends in the radial direction of the case 1. The plurality of mist outlets 13 communicate with the gaps 11 between the adjacent collision wall portions 12 and open to the peripheral wall portion of the case 1. More specifically, the case 1 is configured such that the upper side and the lower side thereof are connected via a plurality of rib-shaped collision wall portions 12. Of the gaps 11 between the collision wall portions 12, the case 1 The portion closest to the outer periphery of 1 is open as it is. This opening portion is a mist jet 13.

  The water reservoir 14 is formed at the bottom of the case 1, and an appropriate amount of water can be stored in the water reservoir 14. For example, as shown in FIG. 3, a water supply tube (not shown) is inserted into a hole 410 provided in the panel 41, and water is supplied into the case 1 from this tube. Can be used. Of course, other means can be used. Of the peripheral wall portion of the case 1, at least a portion near the bottom portion is formed such that its inner diameter becomes smaller as it approaches the bottom portion, thereby reducing the capacity of the water storage portion 14. Accordingly, most of the inner surface of the peripheral wall portion of the case 1 ranging from the vicinity of the formation location of the mist ejection port 13 to the water storage portion 14 is an inclined surface, and water droplets attached to the inner surface enter the water storage portion 14. It is configured to flow smoothly. A part of the inward surface of the collision wall portion 12 (a surface facing the center direction of the case 1) is also an inclined surface for water droplet guide.

  The plurality of air inlets 15 are portions for allowing external air to flow into the case 1 from below. In the present embodiment, the inside of the cylindrical portion 15 a that stands up from the bottom of the case 1 or the vicinity thereof is the air inlet 15. According to such a configuration, the upper part of the air inlet 15 can be made higher than the water surface of the water reservoir 14, so that the water in the water reservoir 14 does not flow down from the air inlet 15 to the bottom of the case 1. Further, since the upper part of the air inlet 15 approaches a rotating plate 20 (described later) of the rotor 2, external air can be reliably and sufficiently supplied to the lower region of the rotating plate 20.

  The rotor 2 is supported by the shaft portion 30 of the motor M and is rotatable in the case 1, and includes a hollow disk-shaped rotating plate 20 and a tubular pumping portion 21 protruding downward from the central portion of the rotating plate 20. And have. The lower end of the pumping unit 21 has a height that can be immersed in the water of the water storage unit 14. When the rotor 2 rotates at a high speed, the water present in the internal space 21 a of the pumping unit 21 rises as a water film along the inner peripheral surface of the pumping unit 21 by centrifugal force and is raised to the upper surface of the rotating plate 20. Then, the water is accelerated from the region near the center of the rotating plate 20 toward the outer peripheral direction by a centrifugal force when the rotating plate 20 rotates at a high speed, and is scattered around the rotating plate 20. It collides with a plurality of collision walls 12.

  The motor M is mounted on the panel 41 and is arranged outside the case 1. The panel 41 also plays a role of partitioning between the motor M and the case 1. However, an air circulation portion 33 for allowing external air to flow into the case 1 from the upper side is formed in a portion where the motor M is attached to the panel 41. The air circulation part 33 includes a gap 33a formed by interposing a spacer 32 between the plate part 31 supporting the motor M and the panel 41, and external air formed in the panel 41 and passing through the gap 33a. And an opening 33b that flows into the case 1. The opening 33 b is located above the rotating plate 20 of the rotor 2.

  Next, the operation of the mist generator MG will be described. In addition, the detailed effect | action at the time of combining this mist generator MG with a bathroom heating apparatus is mentioned later.

  First, in order to generate mist, the rotor 2 is rotated at a high speed in a state where water is stored in the water storage section 14 of the case 1. Thus, as described above, after the water in the water storage unit 14 is pumped up to the upper surface of the rotating plate 20 by the pumping unit 21 of the rotor 2, the water is scattered around the rotating plate 20 at a high speed, and a plurality of collision wall portions 12 hits. As a result, mist is generated. The direction in which the water scatters from the rotating plate 20 is a substantially tangential direction of the rotating plate 20, whereas the plurality of collision wall portions 12 are rib-shaped extending in a direction substantially orthogonal to the collision wall portion 12. Water can be efficiently collided with the wall portion 12.

  Next, the mist generated as described above passes through the gap 11 between the collision wall portions 12 and the mist outlet 13 as it is, and is jetted around the peripheral wall portion of the case 1. The direction of water scattering from the rotor 2 is the horizontal direction, but the direction of the mist generated in the case 1 to the outside also coincides with it. Therefore, the mist is ejected vigorously. Most of the mist is generated in the gap 11 of the collision wall 12, but the path from the gap 11 to the mist outlet 13 is straight and the distance is short. Therefore, the mist generated in the case 1 is easily ejected to the outside of the case 1, and the ratio of water droplets before reaching the mist ejection port 13 is reduced. For this reason, the amount of mist ejection can be increased.

  The mist ejected around the case 1 then descends due to gravity, but there is no portion that prevents the mist from descending, such as the motor M or a part of the case 1, immediately below the ejection region of the mist. Therefore, in the process in which the mist ejected to the outside of the case 1 descends, it is possible to reduce the possibility of contact with a part of the mist generating device MG and forming water droplets. For this reason, it is possible to supply a large amount of mist to the lower region of the mist generating device MG, and when this mist generating device MG is disposed, for example, on the ceiling of the bathroom or in the vicinity thereof, A large amount of mist can be supplied and filled in the bathroom or some areas of the bathroom.

  Even when mist is generated in the mist generating device MG, some mist also forms water droplets in the case 1. Moreover, although it collides with the some collision wall part 12, the water which is not mist-ized can also generate | occur | produce. Such water is returned to the water reservoir 14 along the inner wall surface of the case 1. Since the wide area of the inner surface of the case 1 is an inclined surface, water can flow smoothly toward the water storage unit 14. As described above, when the water that has not been ejected to the outside of the case 1 is returned to the water storage unit 14, the water is sucked up again by the rotor 2 and then repeatedly used for generating mist. Therefore, the trouble that it is difficult to treat the water that has not been ejected to the outside as mist can be avoided appropriately. Moreover, the consumption of water can be suppressed and the amount of water supplied from the outside to the water storage unit 14 can also be reduced.

  As described above, the water storage unit 14 has a smaller diameter than that of the upper region of the water storage unit 14 of the case 1 to reduce the capacity. According to such a configuration, the amount of remaining water when the operation of the mist generator MG is stopped can be reduced. From the viewpoint of hygiene, it is not preferable that much water remains in the case 1 when the operation of the mist generator MG is stopped, and it is desirable to dry the inside of the case 1 at an early stage. On the other hand, according to the present embodiment, such a request can be accurately met.

  When the rotor 2 is rotated at a high speed, the air around the rotating plate 20 swirls to generate turbulent flow. This turbulent flow disturbs the water film on the surface of the rotating plate 20 or disturbs the collision operation of water against the collision wall portion 12 and causes the mist particle diameter to become non-uniform. On the other hand, in the present embodiment, air outside the case 1 is supplied to the upper and lower regions of the rotating plate 20 via the air circulation part 33 and the air inlet 15. This suppresses the surrounding air of the rotating plate 20 from becoming turbulent, and an effect of generating a large amount of mist having a fine and uniform particle diameter is obtained. Even if only one of the air circulation part 33 and the air inlet 15 is provided, the effect of suppressing the turbulent flow described above can be obtained, but both of them are provided. As a result, the effect of suppressing the above-described turbulent flow becomes higher.

  Next, an example of a bathroom heating device provided with the above-described mist generating device MG will be described with reference to FIG.

  A bathroom heating device H1 shown in FIG. 5 is attached to a ceiling plate 80 of a bathroom such as a unit bath, and includes a case 4, a fan 50, and a heat exchanger 51 as an example of a heating unit. The case 4 houses the fan 50 and the heat exchanger 51 inside, and has a lower opening-like case main body 40 installed on the upper surface side of the ceiling plate 80, and a panel 41 separate from this. ing. The panel 41 corresponds to an example of a bottom portion of the case of the bathroom heating device referred to in the present invention. The panel 41 is attached to the ceiling plate 80 so as to close the opening 80 a formed in the ceiling plate 80 and the lower opening of the case main body 40. The panel 41 is provided with an air supply port 41a and a blower port 41b. The air outlet 41b is provided with a louver 42 that can change the air blowing direction.

  In the bathroom heating device H1, when the fan 50 is driven, air is sucked into the case 4 from the air supply port 41a, and this air is heated by the heat exchanger 51. The heat exchanger 51 is configured by using, for example, a plurality of finned tubes in which heated hot water can flow, and the air is heated when passing between the plurality of tubes. The heated air is guided to the louver 42 and blown out. The mist generating device MG is attached to the side of the louver 42 in the panel 41.

  Next, the operation of the bathroom heating device H1 provided with the mist generator MG will be described.

  First, as shown in FIG. 5, when heated air is blown out from the air blowing port 41b toward the lower part of the mist generator MG or near the lower part thereof, the mist generated by the mist generator MG is heated by the heated air. At the same time, it is sent to a certain area in the bathroom by riding this heated air flow. Therefore, the user can take a warm mist. If the heating operation of the heat exchanger 51 is stopped, unheated mist can be bathed.

  Next, when stopping the mist generator MG, for example, as shown in FIG. 6, the angle of the louver 42 is changed so that the heated air blown from the blower port 41 b hits the case 1 of the mist generator MG. To do. If it does in this way, case 1 will be heated and the water which remain | survives in this case 1 or the water adhering to the outer surface of case 1 can be positively evaporated, and the drying can be accelerated | stimulated. Thereby, it can prevent suitably that the inside of case 1 becomes unsanitary.

  The state shown in FIG. 7 is a state in which the operation of the bathroom heating device H1 is stopped and the air blowing port 41b is closed. Even in such a state, the mist can be supplied into the bathroom by operating the mist generator MG alone. In this case, the mist ejected around the case 1 of the mist generator MG only falls spontaneously, but the mist supply in such a manner is also rich in taste.

  Thus, when the mist generating device MG is assembled to the bathroom heating device H1 attached to the upper part of the bathroom, the mist can be efficiently supplied from the upper part of the bathroom toward the lower area. Since the panel 41 of the bathroom heating device H1 serves as a bracket for mounting the mist generating device MG, a dedicated bracket for the mist generating device MG is not required, and installation work is simplified. . Furthermore, as described above, in addition to guiding the mist using the air blowing from the bathroom heating device H1, the effect of being able to dry the case 1 of the mist generating device MG at an early stage is obtained, which is excellent in practicality. .

  8 to 10 show other embodiments 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. 8, the bathroom heating device H <b> 2 is configured as a so-called wall-mounted type that is attached to a position near the ceiling of the bathroom side wall 81. More specifically, in the bathroom heating device H2, when the fan 50 is driven, the bathroom air flows into the case 4 from the air supply port 41a at the top of the case 4 and is heated by the heat exchanger 51. It is comprised so that it may blow out to the bathroom from the ventilation opening 41b of 4 front or side. The mist generator MG is attached to the bottom 41A having the lowest height in the case 4 of the bathroom heater H2.

  In the present embodiment, for example, as shown in the figure, when the blast from the louver 42 passes in the vicinity of the mist generator MG, the mist rides on the blast and is guided to a certain region. In that case, it is also possible to heat the said mist as needed. In this embodiment, it is difficult to directly apply the air blown from the louver 42 to the case 1 of the mist generator MG as compared with the previous embodiment shown in FIGS. Other than that, the same effects as described in the previous embodiment can be obtained.

  The mist generator of the embodiment shown in FIG. 9 includes an auxiliary case 70 that surrounds and supports the motor M. The auxiliary case 70 corresponds to a specific example of the attachment means referred to in the present invention, and the case 1 is connected to the lower portion via a screw body 90. The auxiliary case 70 has, for example, a flange 70b provided with a plurality of holes 70a for screw body insertion in the upper portion thereof, and bolts and nuts 91a and 91b are provided on the lower surface of the wall portion 41B to be attached. It can be attached using a screw member such as.

  By using the auxiliary case 70, the mist generating device of the present embodiment can be used by being attached to, for example, the bottom of a bathroom heating device or the ceiling of a bathroom. Therefore, it is convenient when installing in a bathroom where the bathroom heating device is not installed, or when installing a mist generating device after the bathroom heating device.

  In the embodiment shown in FIG. 10A, the pumping portion 21A of the rotor 2A is non-tubular, and is formed in an inverted truncated cone shape or an inverted cone shape whose outer diameter increases toward the upper end. According to such a configuration, when the rotor 2 </ b> A is rotated at a high speed, the water in the water storage unit 14 becomes a film along the outer peripheral surface of the pumping unit 21 </ b> A and rises to the lower surface of the rotating plate 20. Then, due to the centrifugal force when the rotating plate 20 rotates at a high speed, the water is accelerated on the lower surface of the rotating plate 20 to form a film and scatters around.

The principle of rising by forming a water film on the outer peripheral surface of the pumping portion 21A will be briefly described with reference to FIG. Considering the minute element ΔW of the water film on the outer peripheral surface of the pumped portion 21A, the adhesive force F of water to the outer peripheral surface of the pumped portion 21A is generated in the direction orthogonal to the outer peripheral surface. If the mass of the minute element ΔW is m, mg acts downward in the vertical direction, but this can be broken down into component forces mg _n and mg _t . In the horizontal direction, centrifugal force C (C = mrω ² , r: eccentric distance, ω: angular velocity) acts, but this can be broken down into component forces C _n and C _t . In order to prevent the minute element ΔW from being blown off from the outer peripheral surface of the pumping section 21, it is sufficient if there is a balanced relationship of the following equation (1).
F = C _n + mg _n Formula (1)
Here, since the mass m of the minute element ΔW is m≈0, mg _n is small, and the centrifugal force C and its component force C _n are also small to satisfy the above formula (1). Is possible.
Further, in order for the minute element ΔW to increase, the relationship of the following equation (2) is sufficient.
C _t > mg _t formula (2)
Here, while mg _n is small, the value of C _t can be increased by increasing the rotational speed of the rotor 2A and increasing the angular speed ω, for example. Therefore, the above formula (2) can also be satisfied.

  Also in the present embodiment, it is possible to appropriately generate mist by scattering the water in the water reservoir 14 toward the plurality of collision walls 12. In addition, also in the rotor 2 of embodiment shown in FIGS. 1-4, since the outer peripheral surface of the pumping-up part 21 becomes large diameter upwards, by increasing the rotational speed of this rotor 2, a water storage part 14 water can be advanced from the outer peripheral surface of the pumping portion 21 to the lower surface portion of the rotating plate 20. If it does in this way, the amount of the water which scatters toward the collision wall part 12 can be increased, and the effect which increases mist generation amount further can be anticipated.

  The present invention is not limited to the embodiment described above. The specific configuration of each part of the mist generating device according to the present invention and the bathroom heating device including the mist generating device can be varied in design in various ways.

  For example, as the rotor, 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 scattered as it is 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 as the portion approaches the mist ejection port. Further, although it is preferable to provide the plurality of collision wall portions and the mist outlets over the entire circumference of the periphery of the rotor, they are not provided in some areas, and mist injection from these portions is prevented. It can also be configured. Although it is preferable that the case has a shape with a smaller diameter or width at the lower part, it is not limited to this.

  As the attachment means in the present invention, various other means can be used instead of or in addition to means such as a screw body such as a bolt and a nut, a screw body insertion hole, or a screw hole. The mist generating apparatus according to the present invention is suitable for generating mist in a bathroom (including a shower room), but can also be installed and used in other locations. The purpose of using the mist is not questioned.
