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.

  As an example of a conventional mist generator, a case having a water storage portion for storing water therein, a rotor rotated by a motor, and a collision wall portion provided around the rotor, and When the rotor rotates, there is one in which the rotor sucks up water in the water storage part and then scatters to the collision wall part by centrifugal force (for example, see FIG. 1 of Patent Document 1). According to such a structure, when the water splashed from the rotor collides with the collision wall portion, the water is made into fine water droplets to generate mist, and the mist flows out of the case.

  However, the mist generator as described above has a problem to be solved as described below.

  In other words, water is stored in the water storage unit, but from the viewpoint of preventing the growth of mold and germs in this water storage unit and maintaining hygiene, water remains stored in the water storage unit when the mist generator is stopped. It is requested that it does not become. In particular, when the mist generating device is installed in a bathroom and used for obtaining a mist shower effect or the like, it is necessary to clean the mist, and the above-described demand is stronger. However, in the past, no actual means has been taken to actively deal with such a situation.

  As a means for responding to the above-mentioned demand, for example, a drain pipe provided with an opening / closing valve is connected to the water storage part, and when the operation of the mist generating device is stopped, the opening / closing valve is opened and the drain pipe is used. Thus, it is conceivable that the water in the water reservoir is discharged to the outside. However, if such a means is employed, the structure of the entire apparatus becomes complicated and large, and the manufacturing cost is increased.

Japanese Patent Publication No. 1-101414

  The present invention has been conceived under the circumstances as described above, and it is possible to appropriately prevent a large amount of water from remaining in the apparatus when the operation is stopped by a simple means. An object of the present invention is to provide a mist generator and a bathroom heater provided with the mist generator.

  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 has a case where it has a collision wall part for making water collide, and generating a mist, and a mist spout for ejecting the generated mist outside And a water storage section that is provided integrally or separately in the case and that can store water supplied from the water supply means, and is rotatable by driving a motor, and generates the mist during rotation. A rotor that scatters water in the water reservoir toward the collision wall, an operation-on state in which the motor is driven while water is supplied from the water supply means to the water reservoir, and an operation off in which they are stopped An operation means capable of turning the operation on and off to switch between the states. Even after the water supply operation to the water storage unit is stopped when the operation is performed, the water of the water storage unit is reduced by reducing the amount of water in the water storage unit by generating the mist by continuing the driving of the motor. It is characterized by comprising control means for executing a process for stopping driving.

  According to such a configuration, when the mist generating device is changed from the operation-on state to the operation-off state, a period is provided in which the motor is continuously driven and the rotor rotates in a state where water supply to the water storage unit is stopped. . During this period, mist continues to be generated, and since this mist is ejected to the outside of the case, the water in the water reservoir is consumed and the amount of water in the water reservoir is reduced. Therefore, after the operation of the mist generating apparatus is stopped, it is possible to avoid that a large amount of water remains in the water storage unit, and to appropriately prevent or suppress this portion from becoming unsanitary. Further, in the present invention, it is not necessary to separately provide a piping member or the like for draining water from the water storage section, and it is possible to suitably avoid the complication and enlargement of the structure of the entire apparatus.

  In a preferred embodiment of the present invention, the control means includes a timer, and the motor is operated when a predetermined time has elapsed since the operation was turned off or the water supply operation to the water storage unit was stopped. Is configured to stop driving.

According to such a configuration, the driving of the motor can be stopped at an appropriate time with a simple configuration using a timer.
Of course, in the present invention, unlike the above, a sensor for detecting the water level of the water storage section is used, and the motor is driven when the water level of the water storage section has been lowered to a predetermined level. It is also possible to adopt means such as stopping. Further, when the water level in the water storage section decreases, the load on the motor becomes small. Therefore, it is possible to employ means for stopping the driving of the motor when the current value corresponding to the load on the motor decreases to a predetermined value. Further, instead of such means, the driving of the motor can be stopped when a predetermined operation (for example, a dedicated switch operation for turning off the driving of the motor) is performed by the operating means. .

  In a preferred embodiment of the present invention, the collision wall portion and the mist outlet are provided on a peripheral wall portion of the case, and the water storage portion is formed on a bottom portion of the case, Among these, the inner diameter or the inner width of the portion forming the water storage portion is made smaller than the portion where the collision wall portion and the mist ejection port are provided.

  According to such a configuration, since the inner diameter or inner width of the water storage unit is reduced to reduce the capacity, the amount of water remaining in the water storage unit is reduced when the operation of the apparatus is stopped, and thereafter In addition, it is possible to shorten the time required for discharging water from the water storage section. Moreover, since the said water storage part is formed in the bottom part of the case which forms the collision wall part and the mist jet nozzle, it becomes suitable also for simplifying the whole structure and reducing manufacturing cost.

  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. And a mist generating device.

  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. Moreover, it becomes possible to utilize a bathroom heating apparatus as a bracket of a mist generator, and the construction work of a mist generator can also be abbreviate | omitted or simplified.

  In a preferred embodiment of the present invention, when the operation means is operated to turn off the mist generating device, the air is blown from the air outlet of the bathroom heating device toward the case of the mist generating device. It is configured.

  According to such a structure, evaporation of the water in this case and the water adhering to the outer surface of the case is promoted by the action of blowing air from the air outlet of the bathroom heater to the case. Therefore, for example, an effect of sufficiently drying the case in a state where no water is attached inside and outside the case and an effect that the drying is performed in a short time are obtained, and it is more preferable to keep the mist generating device in a hygienic state. Become.

  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 and 2 show an example of a bathroom heating device provided with a mist generator to which the present invention is applied. The bathroom heating device H of this embodiment is attached to a ceiling 80 of a bathroom such as a unit bath, and a mist generating device MG is attached to the panel 41 of the bathroom heating device H. Prior to the description of the bathroom heating device H, the configuration of the mist generating device MG will be described with reference to FIGS.

  As clearly shown in FIG. 3, the mist generator MG 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 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. The case 1 has 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 inflow ports 15.

  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 rotor 2 to the periphery thereof, and mist is generated by the collision. As shown in FIGS. 4 and 6, the plurality of collision wall portions 12 are configured as ribs arranged radially at substantially equal intervals around the central axis of the case 1. 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 ejection port 13, and mist generated by water colliding with the plurality of collision wall portions 12 passes through the mist ejection port 13 as it is and is ejected around the case 1.

  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. As a means for supplying water to the water storage section 14, for example, as shown in FIG. 3, a relatively small diameter pipe body 92 for water supply is inserted into a hole 410 provided in the panel 41, and the inside of the case 1 is inserted from the pipe body 92. Means for supplying water to the bottom can be used. The tube body 92 is provided with, for example, an electromagnetic on-off valve V1. The pipe body 92 provided with the on-off valve V1 corresponds to an example of the water supply means referred to in the present invention. 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. Along with this, 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 jet 13 to the water storage portion 14 is an inclined surface, and water droplets adhering to the inner surface enter the water storage portion 14. It is configured to flow smoothly.

  The plurality of air inlets 15 are portions for allowing external air to flow into the case 1 from below. When the rotor 2 rotates at a high speed, air around the rotating plate 20 described later becomes turbulent, and this turbulent flow disturbs the operation of generating mist, which causes variation in the mist particle size. 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. A cylindrical portion 15 a erected upward is provided at the bottom of the case 1 or in the vicinity thereof, and the inside is an air inlet 15. According to such a configuration, the upper part of the air inlet 15 can be made higher than the water surface level of the water reservoir 14, and the water in the water reservoir 14 can be prevented from flowing down from the air inlet 15 to the lower part of the case 1. . Further, the upper part of the air inlet 15 can be brought close to the rotating plate 20 of the rotor 2.

  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 the plurality of collision wall portions 12 and mist is generated. Preferably, the dimension s1 of the gap between the lower end of the pumping unit 21 and the bottom surface of the water storage unit 14 is made as small as possible, and is configured to generate mist even when the water level of the water storage unit 14 is quite low. Yes.

  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. Since the external air is also supplied to the upper region of the rotating plate 20 through the air circulation portion 33, turbulence in the air around the rotating plate 20 is more thoroughly suppressed.

  As shown in FIG. 1, the mist generating device MG also includes an operation remote controller 6 and a control unit 7. However, in the present embodiment, the operation remote controller 6 and the control unit 7 are also used for the bathroom heating device H. Of course, the operation remote controller and the control unit may have a configuration in which a mist generator MG and a bathroom heater H are separately provided. The operation remote controller 6 corresponds to an example of the operation means in the present invention. For example, data can be transmitted to the control unit 7 by performing infrared transmission to an infrared light receiving unit (not shown) provided in the bathroom heating device H. It is possible to perform a command operation such as turning on / off the operation of the mist generator MG. The control part 7 is comprised using the microcomputer, for example, and performs operation control of each part of the mist generating apparatus MG and the bathroom heating apparatus H. However, the specific control content will be described later.

  Next, the configuration of the bathroom heating device H will be described.

  As shown in FIG. 1, the bathroom heating device H includes a case 4, a fan 50, and a heat exchanger 51 as an example of a heating unit. 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 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 H, 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 through which heated hot water can flow, and the intake air by the fan 50 is heated when passing between the plurality of tubes. . The heated air is guided to the louver 42 and blown out. The case 1 of the mist generator MG is located on the side of the louver 42.

  Next, the operation of the bathroom heating device H provided with the mist generator MG will be described. An example of the operation procedure of the control unit 7 when the operation of the mist generator MG is turned off will be described with reference to the flowchart of FIG.

  First, when the operation remote control 6 is operated and an operation on command is given, the on-off valve V1 is opened and water supply to the water storage section 14 of the mist generator MG is started. Further, driving of the motor M is also started. As a result, as described above, 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, then scatters around it and collides with the plurality of collision wall units 12. Mist is generated. The mist generated in this way 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.

  When the mist is ejected, for example, as shown in FIG. 1, when heated air is blown out from the blower opening 41 b of the bathroom heating device H toward the lower part of the case 1 or near the lower part thereof, the mist is ejected around the case 1. Is heated by the heated air and 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, unheated mist can be bathed. Further, unlike these, it is also possible to stop the operation of the bathroom heating device H 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 such a manner is also rich in taste.

  When mist is generated in the mist generator MG, a part of the mist is converted into 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.

  On the other hand, when the operation remote controller 6 is operated to turn off the mist generator MG as described above, the control unit 4 first closes the on-off valve V1 and supplies the water storage unit 14 to the water storage unit 14. Water supply is stopped (S1: YES, S2). However, the driving of the motor M is not stopped, and the rotor 2 is kept rotating. As a result, the operation in which the water in the water storage unit 14 is made mist and discharged to the outside of the case 1 is continued, and the amount of water in the water storage unit 14 decreases.

  The controller 4 immediately sets a timer when the on-off valve V1 is closed (S3). Moreover, as shown in FIG. 2, the control which makes warm air blow from the ventilation opening 41b of the bathroom heating apparatus H with respect to the case 1 of the mist generator MG is also performed (S4). When the bathroom heating apparatus H is already in an operating state as shown in FIG. 1, for example, it is possible to set the state shown in FIG. 2 is set in the state shown in FIG. 2 after the operation of the bathroom heating device H is started. As described above, when the hot air is blown to the case 1, the case 1 is heated and water remaining in the case 1 or water adhering to the outer surface of the case 1 is positively evaporated. be able to.

  Thereafter, when the first set time predetermined by the timer is counted, the control unit 7 stops driving the motor M at that time (S5: YES, S6). According to such control, the rotor 2 is rotating during the first set time period even after the water supply to the water storage unit 14 is stopped, and the amount of water in the water storage unit 14 during this period. Can be sufficiently reduced. The first set time can be set to an appropriate value by conducting a test or the like in advance so that such an effect can be appropriately obtained.

  If the dimension s1 of the gap between the lower end portion of the rotor 2 and the bottom surface of the water storage portion 14 shown in FIG. 3 is set to zero or a value close to this, the amount of water in the water storage portion 14 is brought close to almost zero only by the rotational operation of the rotor 2. It is possible. Further, as described above, since the water storage unit 14 is smaller in diameter than the upper region of the water storage unit 14 of the case 1 and has a reduced capacity, the operation of the mist generator MG is stopped. The amount of water in the water storage section 14 to be discharged to the outside by the rotation of the rotor 2 is small. Therefore, there is an advantage that it is possible to shorten the time (first set time) for which the motor M is driven after the water supply to the water storage unit 14 is stopped.

  Thereafter, when the second set time set in advance by the timer is counted, the control unit 7 stops hot air blowing from the blower opening 41b of the bathroom heating device H toward the case 1 at that time (S7). : YES, S8). Preferably, the second set time is longer than the first set time. By blowing hot air to the case 1, all the water remaining in the water storage unit 14 can be evaporated, and water attached to other parts such as the inner surface and outer surface of the case 1 and the rotor 2 can also be evaporated, The case 1 and the rotor 2 can be sufficiently dried. Therefore, such a problem that mold and germs easily propagate due to moisture remaining on the case 1 and the rotor 2 is preferably avoided. In addition, when drying case 1, although it is preferable to utilize a warm air, it is not limited to this. Non-warm air (non-heated air) may be blown from the air blowing port 41b to the case 1. In this case, the case 1 cannot be heated, but drying of the case 1 can be promoted by a blowing action.

  FIG. 8 shows another embodiment of the present invention. In the figure, the same or similar elements as those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the embodiment shown in FIG. 8A, 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 that a water film is formed on the outer peripheral surface of the pumping portion 21A and rises 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 the rotor 2 of the previous embodiment, since the outer peripheral surface of the pumping section 21 has a larger diameter toward the upper side, the water in the water storage section 14 is increased by increasing the rotational speed of the rotor 2. It is also possible to advance from the outer peripheral surface of 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.

  When the operation of the mist generator is turned off, it is preferable to reduce the amount of water remaining in the reservoir as much as possible, but the amount of water does not necessarily have to be zero or close to zero. Even within the technical scope of the present invention. In the present invention, after the water supply to the water storage unit is stopped, the motor may be continuously driven to reduce the amount of water in the water storage unit. If the amount of water in the reservoir is reduced in this way, compared with the case where such a decrease in the amount of water is not caused, for example, the subsequent natural drying of the reservoir is performed at an early stage, and an advantage of excellent hygiene is obtained. It is done.

  The water storage part may be configured using a member separate from the case in which the collision wall part and the mist ejection port are formed. The specific shape, arrangement, number, and the like of the collision wall portion and the mist outlet are not limited. The operation means referred to in the present invention does not need to be a remote control capable of wireless communication, and can be of a type connected to the control means, for example. Of course, as described above, it may also be used for a bathroom heating device, or may be used for other devices (for example, a hot water supply device).

  The mist generator according to the present invention can be used by being attached to a so-called wall-mounted bathroom heater attached to a bathroom side wall, for example, instead of the ceiling-mounted bathroom heater as in the above embodiment. . Moreover, it may replace with a bathroom heating apparatus, for example, may be directly attached to the ceiling part (ceiling panel etc.) of a bathroom, for example, irrespective of the presence or absence of a bathroom heating apparatus. 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.
