Description

  The present invention provides a mist generating device configured by combining a mist generating device of a type that generates mist by splashing water using a rotor that can be driven and rotated, and a bathroom air conditioner such as a bathroom heating dryer. It relates to the bathroom air conditioning system provided.

  As a mist generator 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 (rotor) that can be driven and rotated 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.

  The mist generating device described above is configured as a floor-mounted type that is used by being installed on the bathroom floor. However, in such a type, it is difficult to fill the mist with a wide area of the bathroom, It is difficult to take a mist shower all over the body. Therefore, the present inventors attach the mist generating device as described above to the ceiling of the bathroom, or to the bathroom air conditioner installed at the upper part of the bathroom, and to the peripheral wall of the case that houses the rotor The idea is that the mist ejected from the ejection port can be smoothly supplied downward from the upper part of the bathroom.

  However, when the above-described means is employed, problems to be solved arise as described below.

  That is, since the mist generating device is configured such that the mist is ejected around the case housing the rotor, the bathroom air conditioner provided separately at the upper part of the bathroom during the mist ejection When air is blown out from the air, it is affected by this air. When affected by such air, a part of the mist ejected to the outer periphery of the case may flow toward the outer peripheral surface of the case, and many water droplets may adhere to the outer peripheral surface of the case. If such a phenomenon occurs, a water drop may fall from the case of the mist generating device toward the lower side of the mist generating device, and this may hit the bather, which may cause discomfort to the bather. Therefore, it is desirable to appropriately eliminate such a concern.

JP-A-8-182727

The present invention has been conceived under the circumstances as described above, and includes a mist generating device capable of appropriately suppressing a problem that a water droplet falls from a case of the mist generating device to the lower side thereof.

According to such a configuration, when water droplets are generated on the outer surface of the peripheral wall portion of the case of the mist generating device, most of the water droplets are received by the flange-shaped protrusions, and the received water droplets are passed through the water opening. Can be guided from the part into the case. Therefore, when mist is ejected around the case, even if water droplets are generated in the portion due to the air blowing from the bathroom air conditioner and the mist coming into contact with the peripheral wall portion of the case, the water droplet It is preferably suppressed that most of the water flows down below the case and hits the bather.
Furthermore, according to the said structure, by making water collide with a some collision wall part, the mist with a small particle diameter can be generated suitably, and this mist can be efficiently ejected from the mist outlet to the exterior of a case. . In addition, when water droplets are generated on the surfaces of the plurality of collision wall portions and flow downward, the water droplets are received by the upper surface of the flange-shaped protruding portion, and are prevented from falling below the case. Furthermore, since the area | region between several collision wall parts is made into the opening part for a mist jet nozzle and water flow, the structure is rational and can also simplify the structure of a case.

  According to such a configuration, since air is blown from the auxiliary blower port provided near the blower port of the bathroom air conditioner toward the case of the mist generator, the mist generator is caused by the action of the air blower. It is possible to obtain an effect of suppressing a large amount of mist from being ejected from the mist jet port toward the auxiliary blower port and the blower port side. Therefore, it is avoided that the mist is greatly affected by the air blowing from the blower opening, and the amount of mist that adheres to the case of the mist generating device and forms water droplets is reduced. As a result, the problem that many water drops fall from the case of the mist generator and hit the bather is suitably suppressed.

In a preferred embodiment of the present invention (not described in the claims) , the bathroom air conditioner includes a louver having the air outlet, and the auxiliary air outlet is provided on a side wall of the louver. Thus, a part of the air supplied into the louver is discharged from the auxiliary air outlet to the outside.

  According to such a configuration, it is not necessary to separately provide an air flow path for supplying air to the auxiliary air outlet, compared to the case where the auxiliary air outlet is provided in a member different from the louver of the bathroom air conditioner. The configuration can be simplified and an increase in manufacturing cost can be suppressed.

  According to such a configuration, since a large amount of mist is not ejected from the mist generating device to the air outlet side of the bathroom air conditioner, it is greatly affected by the air blowing from the air blowing port ejected from the mist generating device. Can be avoided, and a phenomenon in which a large amount of mist adheres to the case of the mist generating device to form water droplets can be suppressed. As a result, it is also preferable to prevent a large number of water droplets from dropping from the case of the mist generating device downward.

  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.

[First Embodiment]
1-6 has shown an example of the structure related to the bathroom air conditioning system provided with the mist generating apparatus with which this invention was applied. As shown in FIG. 1, the bathroom air conditioning system S1 of the present embodiment includes a bathroom air conditioner A attached to a ceiling 80 of a bathroom such as a unit bath, and mist generation assembled to a panel 41 of the bathroom air conditioner A. Device MG.

  As clearly shown in FIG. 2, the mist generator MG includes a case 1, a rotor 2 having a rotating plate 20, and a motor M for driving and rotating the rotor 2.

  The case 1 is made of a synthetic resin, and its schematic shape is a cup shape having a circular shape in plan view with an upper portion opened. The case 1 is attached to the lower surface portion of the panel 41 using a plurality of screw holes 10 provided in the upper portion thereof and a screw body 90 screwed into these. In this case 1, a plurality of collision wall portions 12, a plurality of mist jets 13, a flange-like protrusion portion 17, an auxiliary peripheral wall portion 11, and a water storage portion 14 are provided.

  The plurality of collision wall portions 12 are portions for causing the water to collide when the rotor 2 rotates and the water is scattered around the rotating plate 20, and the collision generates a relatively fine mist. Can do. However, it is also possible to generate mist only by scattering water from the rotating plate 20 at a high speed without providing the collision wall portion 12. As shown in FIG. 4, the plurality of collision wall portions 12 are arranged in a radial pattern around the center of the case 1 at substantially equal intervals, and have a rib shape extending in the radial direction of the case 1. A gap between the collision wall portions 12 adjacent to each other is opened toward the periphery of the case 1, and this opening portion is a mist ejection port 13. Mist generated by water colliding with the plurality of collision wall portions 12 passes through the mist ejection port 13 and is ejected around the case 1.

  As will be described later, the flange-shaped projecting portion 17 is a portion that receives a water droplet flowing from a portion above the projecting portion 17, and is below the mist ejection port 13 in the peripheral wall portion of the case 1. And protrudes toward the periphery of the case 1. The projecting portion 17 is formed over the entire circumference of the peripheral wall portion of the case 1, and the lower surfaces of the plurality of collision wall portions 12 are connected to the upper surface thereof.

  The auxiliary peripheral wall portion 11 is a portion that guides the generated water droplets to the upper surface of the flange-shaped projecting portion 17 and other portions that will be described later, and is separated from the case 1 around the plurality of collision wall portions 12. It is provided by winding and joining a belt-shaped member. Of course, unlike the present embodiment, the auxiliary peripheral wall portion 11 can be integrally formed with the case 1. The auxiliary peripheral wall portion 11 is provided on the upper side and the lower side so that a plurality of mist jets 13 and a plurality of water-passing openings 18 are formed. The water passage opening 18 is a part for guiding water drops received by the upper surface of the protrusion 17 into the case 1, and the vertical opening width thereof is relatively small. As clearly shown in FIG. 3, the lower portion 11 a of the auxiliary peripheral wall portion 11 is located closer to the center of the case 1 than the outer peripheral edge 17 a of the protruding portion 17, and propagates downward on the surface of the auxiliary peripheral wall portion 11. Water droplets are appropriately guided onto the upper surface of the protrusion 17.

  The water reservoir 14 is formed at the bottom of the case 1 and can store an appropriate amount of water. Water for generating mist can be supplied to the water storage unit 14 from the outside through a water supply pipe 92. The water supply pipe 92 is provided with, for example, an electromagnetic on-off valve V1 as means for controlling on / off of water supply.

  The rotor 2 is supported by the drive shaft 30 of the motor M and accommodated in the case 1. In addition to the rotating plate 20 described above, the shaft portion for pumping water that protrudes downward from the center portion of the rotating plate 20. 21. Each part of the rotor 2 is made of, for example, a synthetic resin, but is not limited thereto. The shaft portion 21 has a conical shape or truncated cone shape with a larger diameter toward the upper portion, and the lower portion thereof is located in the water storage portion 14. During the rotation of the rotor 2, the water in the water reservoir 14 rises as a water film along the outer peripheral surface of the shaft-like portion 21 and is raised to the lower surface of the rotating plate 20 according to the principle described later. Then, the water is accelerated from the region near the center of the rotating plate 20 toward the outer periphery by centrifugal force, and is scattered around the rotating plate 20.

FIG. 6 is a diagram for explaining the principle of the operation described above. With reference to the figure, the principle that a water film is formed on the outer peripheral surface of the shaft-shaped portion 21 and rises will be described.
Considering the minute element ΔW of the water film on the outer peripheral surface of the shaft-shaped portion 21, the adhesive force F of water to the outer peripheral surface of the shaft-shaped portion 21 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 shaft-shaped portion 21, it is sufficient if there is a balanced relationship of the following expression (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 2 and increasing the angular speed ω, for example. Therefore, the above formula (2) can also be satisfied.
Thus, if the rotor 2 is rotated at a high speed so as to satisfy the above-described formulas (1) and (2), a pumping action for raising the water in the water storage section 14 along the outer peripheral surface of the shaft-shaped section 21 is obtained. be able to.

  A cylindrical portion 15 a is provided at the bottom of the case 1, and a plurality of air inlets 15 for allowing external air to flow into the case 1 are also provided. When the rotor 2 rotates at high speed, the air around the rotating plate 20 becomes a turbulent flow, and this turbulent flow disturbs the operation of generating the mist and causes a variation in the particle size of the mist. On the other hand, if external air is supplied to the lower part of the rotating plate 20 from the plurality of air inlets 15, the above-described turbulent flow can be suppressed.

  The motor M is mounted on the panel 41 and is controlled by the control unit 7 (see FIG. 1) configured using a microcomputer or the like, similar to the on-off valve V1. Preferably, an air flow passage 33 through which external air can flow into the case 1 from above is provided at the mounting position of the motor M. For example, the air circulation portion 33 includes a gap 33a formed by interposing a spacer 32 between the plate portion 31 supporting the motor M and the panel 41, and an external portion formed in the panel 41 and passing through the gap 33a. And an opening 33 b through which air flows into the case 1. Since external air is also supplied to the upper region of the rotating plate 20 via the air circulation portion 33, turbulent flow is also prevented from occurring in the peripheral air.

  As shown in FIG. 1, the bathroom air conditioner A includes a case 4, a fan 50, and a heat exchanger 51 as heating means. The case 4 accommodates the fan 50 and the heat exchanger 51 therein, and includes a case body 40 having a lower opening shape installed on the upper surface side of the ceiling plate 80 of the bathroom, and a panel 41 separate from this. Have. 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 a louver 42 having an air supply port 41a and 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 in which heated hot water can flow, and the intake air from the fan 50 is heated when passing between the plurality of tubes. . The heated air is guided into the louver 42 and blown out from the air blowing port 41b. The case 1 of the mist generator MG is located on the side of the louver 42.

  Next, the operation of the bathroom air conditioning system S1 including the mist generator MG described above will be described.

  First, when operating the mist generator MG, the on-off valve V1 is opened, water supply to the water storage unit 14 is started, and the motor M is driven. As described above, a part of the water stored in the water storage part 14 rises to the lower surface of the rotating plate 20 along the outer peripheral surface of the shaft-like part 21 by the rotating action of the shaft-like part 21 of the rotor 2. To the surroundings and collide with a plurality of collision wall portions 12. Mist generated by the collision passes through the plurality of mist outlets 13 and is jetted around the peripheral wall portion of the case 1.

  When the mist is ejected, for example, as indicated by an arrow N1 in FIG. 1, when heated air is blown out from the air blowing port 41b of the bathroom air conditioner A toward the lower part of the case 1 or near the lower part thereof, the case 1 is surrounded. The ejected mist is heated by the heated air and is sent to a certain area in the bathroom along the flow of the heated air. Therefore, the user can concentrate on the warm mist. If the heating operation of the heat exchanger 51 is stopped, a non-heated mist can be taken, and a refreshing feeling can be obtained in summer and the like. Unlike these, it is also possible to stop the operation of the bathroom air conditioner A and use the mist generator MG alone in a state where the air blowing from the air blowing port 41b is stopped. In this case, the mist ejected around the case 1 only falls spontaneously, but the mist supply in this manner is also rich in taste.

  When a part of the mist comes into contact with the outer surface of the peripheral wall portion of the case 1 at the time of mist ejection, water droplets are generated in that part. As shown by the arrow N1 in FIG. 1, when air blowing is performed downward (including obliquely downward, the same applies hereinafter), the mist ejected around the case 1 is affected by the air blowing, and the arrows N2, N3 As shown in FIG. 4, a phenomenon of descending along the periphery of the case 1 occurs, so that water droplets are easily generated on the outer surface of the peripheral wall portion of the case 1. However, water droplets generated at a position higher than the flange-shaped projecting portion 17 in the peripheral wall portion of the case 1 are received by the upper surface of the projecting portion 17 when flowing downward thereafter, and the water-passing opening portion 18 is formed. Into the case 1. As a result, it is possible to reduce the amount of water droplets flowing toward the bottom of the case 1 and to reduce the amount of water dropped from the case 1 downward.

  The auxiliary peripheral wall portion 11 serves to guide water droplets adhering to the plurality of collision wall portions 12 to the upper surface of the flange-like projecting portion 17 and, as will be described below, below the flange-like projecting portion 17. It also serves to suppress the generation of water droplets in the area. That is, the phenomenon that the mist ejected from the mist ejection port 13 forms water droplets on the outer surface of the peripheral wall portion of the case 1 is likely to occur near the lower edge of the mist ejection port 13. For this reason, unlike the present embodiment, for example, when the auxiliary peripheral wall portion 11 is not provided and the flange-like projecting portion 17 is provided close to the mist outlet 13, the lower portion is lower than the projecting portion 17. There is a high possibility that mist is generated in the region. This makes it difficult to collect water droplets using the protrusion 17. On the other hand, in the present embodiment, since the auxiliary peripheral wall portion 11 is interposed between the mist ejection port 13 and the protruding portion 17, mist water droplets are likely to occur on the surface of the auxiliary peripheral wall portion 11. This water droplet can be appropriately guided to the upper surface of the protrusion 17.

  Further, as the mist generated in the case 1, there is a mist that proceeds in the direction of the outer peripheral edge 17 a of the flange-shaped protrusion 17 as indicated by an arrow N <b> 4 in FIG. 3. On the other hand, in the present embodiment, such mist can be blocked by the auxiliary peripheral wall portion 11 so as not to reach the outer peripheral edge 17a. When the mist reaches the outer peripheral edge 17a, many water droplets are generated in this portion and dropped downward, but according to the present embodiment, such a situation is also appropriately prevented. For this reason, it is possible to further prevent water droplets from dropping below the case 1.

  Some of the water scattered from the rotor 2 toward the collision wall portion 12 is not sprayed outside the case 1. Such water travels along the inner wall surface of the case 1 and is returned to the water reservoir 14 (the same applies to the water droplets received by the flange-shaped protrusion 17). Then, such water is pumped to the lower surface of the rotating plate 20 by the shaft-like portion 21 of the rotor 2 and then reused 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 utilization factor of water increases and the effect that the consumption is suppressed is also acquired.

  When stopping the operation of the mist generating device MG, after stopping the water supply to the water storage unit 14, the rotor 2 is set so that substantially the entire amount of water remaining in the water storage unit 14 is misted and consumed. What is necessary is just to drive continuously for an appropriate time. As a result, the fact that much water remains in the case 1 is eliminated, and the case 1 can be made sanitary. Moreover, the case 1 and the rotor 2 can also be dried at an early stage by setting the louver 42 of the bathroom air conditioner A in a predetermined direction and blowing air to the case 1 from the air blowing port 41b.

  In the said embodiment, although the flange-shaped protrusion part 17 is provided over the perimeter of the surrounding wall part of case 1, this invention is not limited to this. For example, when air is blown from the air blowing port 41b in the state shown in FIG. 1, water droplets tend to be most likely to occur in a portion near the air blowing port 41b in the peripheral wall portion of the case 1. For this reason, it can also be set as the structure which provided the flange-shaped protrusion part 17 only in such a part. The same applies to the auxiliary peripheral wall portion 11, and a configuration in which the auxiliary peripheral wall portion 11 is partially provided on a part of the peripheral wall portion of the case 1 may be employed.

[Second Embodiment]
FIG. 7 shows a second embodiment of the present invention. In FIG. 7 and subsequent figures, the same or similar elements as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and detailed description thereof is omitted.

  In the bathroom air conditioning system S2 shown in FIG. 7, an auxiliary air outlet 43 is provided on the side wall of the louver 42 of the bathroom air conditioner A. When the louver 42 is set to an angle at which the louver 42 blows air downward from the blower port 41b as indicated by an arrow N11, the auxiliary blower port 43 faces the case 1 of the mist generator MG and, as indicated by an arrow N13, Air can be blown from one side of the case 1 toward the peripheral wall. Air blowing from the auxiliary air blowing port 43 is performed by guiding a part of the air supplied from the fan 50 into the louver 42 by the guide 44. For example, the guide 44 has a configuration in which a part thereof is positioned in the louver 42 and extends in a substantially horizontal direction. In the drawing, the guide 44 is integrally formed with the louver 42, but the present invention is not limited to this. For example, the guide 44 can be provided movably using a separate member, and the guide 44 can be normally closed, and the auxiliary air outlet 43 can be opened only when necessary.

  About the mist generating apparatus MG, Preferably, the flange-shaped protrusion part 17 is provided in the surrounding wall part of the case 1 similarly to the said 1st Embodiment. In this case, the lower region of the gap between the plurality of collision wall portions 12 corresponds to the opening 18 for water flow. In the drawing, the auxiliary peripheral wall portion 11 is not provided, but a configuration in which the auxiliary peripheral wall portion 11 is provided is also possible. These points are the same in the third embodiment described later.

  In the present embodiment, mist is generated in the mist generator MG, and air is blown from the auxiliary blower port 43 to the peripheral wall portion of the case 1 when air is blown from the blower port 41b to the lower part of the bathroom. Can be done. When such air blowing is performed, the air blowing becomes resistance, so that it is difficult for a large amount of mist to be ejected from the case 1 toward the auxiliary air blowing port 43, and the amount of mist ejected to a region near the louver 42 is small. Become. As a result, the amount of water droplets generated at the portion of the peripheral wall portion of the case 1 near the louver 42 is also reduced. As described above, when air is blown downward from the air blowing port 41b, water droplets are likely to be generated in a portion of the peripheral wall portion of the case 1 near the air blowing port 41b. By reducing the amount of water droplets generated at such a portion, it is possible to suitably suppress the drop of water droplets from the case 1 downward.

  In addition, when air is blown downward from the blower opening 41b as indicated by an arrow N11, the airflow is essentially on the side of the case 1 opposite to the louver 42 as indicated by an arrow N12 in FIG. The air in the area is also drawn into the air blowing area. Such a phenomenon is not preferable because it promotes the formation of water droplets in the mist. On the other hand, according to the present embodiment, the air blown out from the auxiliary air blowing port 43 bypasses the periphery of the case 1 or passes through the case 1, so that the louver 42 around the case 1 is It is possible to reach the opposite area. In this way, the phenomenon that mist is drawn in the direction indicated by arrow N12 is suppressed, and the occurrence of water droplets in case 1 is further prevented.

  The auxiliary air outlet 43 is provided in the louver 42 having the air outlet 41b, and a part of the air supplied into the louver 42 is used as the air. For this reason, the structure for providing the auxiliary air outlet 43 is simple, and it is possible to suppress an increase in manufacturing cost. However, the present invention is not limited to this, and the auxiliary air outlet 43 can be provided in a member or a part different from the louver 42.

[Third Embodiment]
In the bathroom air-conditioning system S3 shown in FIG. 8, a part of the peripheral wall portion of the case 1 of the mist generating device MG near the louver 42 is a wall portion 19 in which the mist outlet 13 is not opened, The mist outlet 13 is configured to be provided in the other part of the peripheral wall portion of the case 1. As shown in FIG. 9, the circumferential width of the wall portion 19 is, for example, about 1/4 to 1/3 of the entire circumferential length of the case 1. The plurality of collision wall portions 12 are also provided inside the wall portion 19, and are arranged at substantially constant intervals over the entire circumference of the peripheral wall portion of the case 1. In the present embodiment, the wall portion 19 is integrally formed with the other part of the case 1. However, instead of this, the wall portion 19 is a separate member from the case 1, and the mist outlet 13 is formed by this separate member. You may comprise so that it may block.

  According to the present embodiment, when the mist is ejected from the case 1 of the mist generator MG, the mist is not ejected toward the air outlet 41b side of the bathroom air conditioner A in the periphery of the case 1. Therefore, the mist does not come into contact with the peripheral wall portion of the case 1 on the air blowing port 41b side due to the influence of the downward air blowing from the air blowing port 41b, and water drops are reduced. As a result, also in the present embodiment, as in the above-described embodiments, it is appropriately suppressed that many water droplets fall from the case 1 downward.

  Moreover, in this embodiment, since the several collision wall part 12 is provided also inside the wall part 19, many mists can be generated. In the present invention, for example, as shown in FIG. 10, it is possible to adopt a configuration in which the collision wall portion 12 is not provided inside the wall portion 19, but in such a configuration, the amount of mist generated is reduced. . On the other hand, according to this embodiment, such a thing can also be eliminated.

  The present invention is not limited to the embodiment described above. The specific configuration of each part of the bathroom heating system provided with the mist generator according to the present invention can be varied in design in various ways.

  For example, the rotor 2 as shown in FIG. 11 can be used as the rotor of the mist generating device MG. The rotor 2 has a pipe shape in which the shaft-shaped portion 21 has a hole 210. When the rotor 2 rotates, the water located in the hole 210 of the shaft-shaped part 21 rises in a film shape along the inner peripheral surface of the hole 210 by the action of centrifugal force and reaches the upper surface of the rotating plate 20. To do. Next, this water is accelerated by centrifugal force on the upper surface of the rotating plate 20 to form a water film, and is scattered toward the periphery of the rotating plate 20 to generate mist. The mist generator in the present invention basically has only to have a function of generating mist by scattering water around the rotor by the rotation of the rotor, and has a specific shape such as a rotor or a case. The material can be changed as appropriate.

  The bathroom air conditioner may be a so-called wall-mounted type that is attached to the side wall of the bathroom, for example, instead of the ceiling-mounted type as in the above-described embodiment. Moreover, if the mist generating device is assembled to the bathroom air conditioner, the overall structure and the like can be simplified and the space can be saved. However, the configuration is not limited to this. The bathroom air conditioning system according to the present invention may be configured to be installed in the bathroom in a state where the bathroom air conditioner and the mist generating device are separated. Further, the bathroom referred to in the present invention includes a shower room.
