The ultrasonic transducer 10 is a commercially available product using a disk-shaped piezoelectric ceramic as a vibration source, and vibrates the mist stock solution in the stock solution container 8 to form fine mist by applying a high frequency alternating voltage. The ultrasonic transducer 10 is fixed to the tank bottom wall in a state where its upper surface faces the vibration window 16 opened in the bottom surface of the stock solution container 8. The code | symbol 17 is seal rubber which seals the circumference | surroundings of the ultrasonic transducer | vibrator 10. As shown in FIG.

  The mist feeding path 3 is formed by a feeding cylinder 20 consisting of a divided cylindrical body in front and rear, and the cold mist generated by the ultrasonic transducer 10 is generated by the flow action of the pressurized air introduced from the air inlet 13. It is conveyed along the mist feed path 3. The feeding cylinder 20 includes a mist inlet 21 at the lower end, a mist outlet 22 at the upper end, and a heating chamber 23 provided in the middle in the vertical direction, and the entire space from the mist inlet 21 to the mist outlet 22. Functions as the mist feed path 3. In a state where the feeding cylinder 20 is mounted and fixed to the mounting port 12 of the stock solution container 8, the mist inlet 21 is positioned inside the stock solution container 8 and faces the liquid level directly above the ultrasonic transducer 10. The mist outlet 22 is exposed to the outer surface of the case at the upper part of the inclined wall on the upper surface of the body case 1. That is, the mist inlet 21 faces the mist generator 2 inside the stock solution container 8.

  The mist inlet 21 includes an inlet passage 24 continuous with the lower portion of the heating chamber 23 and a bell-mouth shaped mist introducing portion 25 gradually expanding from the inlet passage 24 toward the mist generating portion 2. The opening end of the portion 25 is located directly above the mist generating portion 2. Further, the mist outlet portion 22 includes an outlet passage 26 continuous with the upper portion of the heating chamber 23 and a bell mouth-like mist discharge portion 27 continuous with the outlet passage 26.

It can be fed into the chamber 23. Therefore, the cold mist generated by the ultrasonic transducer 10 is prevented from filling the stock solution container 8 and causing condensation and flowing down, so that all the generated cold mist can be effectively used.

  A heating body K is disposed in the heating unit 4. The heating element K is a unit body in which a commercially available PTC heater (electric heating element) 30 whose entire surface is covered with a waterproof coating and a pair of front and rear aluminum heat transfer blocks 31 sandwiching the PTC heater 30 from the front and rear are integrated. Thus, the heat of the electric heating body 30 is radiated by the heat transfer block 31, and the cold mist in the mist feed path 3 is heated to form a warm mist. As shown in FIG. 2, the PTC heater 30 is disposed in the central portion of the round cylindrical heating chamber 23, and the heat transfer block 31 is disposed on the front and back surfaces thereof. The heat transfer block 31 includes a base wall 32 in close contact with the PTC heater 30 disposed adjacent to the upper and lower sides, and seven heat transfer ribs 33 projecting in parallel from the wall 32 toward the inner surface wall of the heating chamber 23. It is configured as a heat sink. The cold mist conveyed by the pressurized air is heated and converted into a warm mist while passing through the heat transfer passages 34 between the heat transfer ribs 33.

  The previously described barb members 28 engage with the heat transfer ribs 33 adjacent to the left and right and project into the heat transfer passage 34, and a part of the cold mist is trapped by the upper and lower barb members 28, The flow direction of the cold mist is changed, and the flow velocity is further reduced to increase the contact opportunity with the heat transfer rib 33. The weir body 28 also serves as a holding projection for fixing and holding the heat transfer block 31 to the heating chamber 23, and each weir body 28 is engaged between the heat transfer ribs 33 to stop the heating body K from rotating. Support in a stable condition. The cold mist is heated by the heat conduction action when contacting the heat transfer rib 33 and the surface of the PTC heater 30, and at the same time, is also heated by the radiant heat radiated from the heat transfer rib 33 and the PTC heater 30. . In other words, regarding the heat transfer opportunity and contact time between the cold mist and the heating element K, not only the heat transfer effect due to the direct contact between the cold mist and the heating element K but also the radiant heat that does not directly contact the cold mist and the heating element K. Heat transfer opportunities and contact time can also be increased by heat transfer. As described above, the heating unit 4 heats the electric heater 30 which generates heat by electric power and the heat generator K having the heat transfer block 31 which radiates the heat of the electric heater 30 to heat the cold mist, and a part of the cold mist It is comprised with the damming body 28 which stops and changes the flow direction.

  On the rear side of the feed cylinder 20 inside the main body case 1, a blower unit 37 that generates an air flow for mist conveyance is provided. The blower 37 includes a blower fan 38 that sucks and pressurizes the outside air of the main body case 1, a motor 39 that rotationally drives the blower fan 38, an air passage 40 that flows and guides the air flow pressurized by the blower fan 38, and the like. Composed of The air passage 40 has a first passage 41 for feeding and guiding the pressurized air flow to the stock solution container 8 and a second passage for feeding and guiding the pressurized air flow to the outside of the main body case 1. 42, and a blower fan 37 is disposed in a wind tunnel 43 provided at a branch portion of both the passages 41 and 42. The first passage 41, the second passage 42, and the air channel portion 43 are formed by the air channel case 40A which is branched into two. That is, the air passage 40 is formed by the wind tunnel case 40A that accommodates the blower fan 38 and the motor 39. Reference numeral 44 denotes a filter provided in the air suction port 43 a of the air passage 40. The first passage 41 communicates with the air inlet 13 via an elbow 45, and the pressurized air blown from the air inlet 13 into the stock solution container 8 is accompanied by cold mist generated by the ultrasonic vibrator 10. Flows from the mist inlet 21 into the mist feed path 3. The motor 39 is rotationally driven by the direct current rectified by the rectifier circuit shown in FIG. The rectifier circuit includes a diode bridge 48 for full-wave rectification of the AC current of the commercial power supply, a noise prevention capacitor 49 connected in parallel with the motor 39, and a dropper resistor 50 for reducing the voltage of the drive current of the motor 39. It is The alternating current before rectification is introduced into the main body case 1 through a power cord connected to a commercial power source, and is stepped down by the dropper resistor 50 and then rectified by the diode bridge 48. The dropper resistor 50 is formed of a coil body of a resistance wire formed in a compression coil spring shape.

  The 2nd channel | path 42 is formed over the upper surface of the main body case 1 from the wind tunnel part 43, and the blowing nozzle 53 is provided in the upper end. The blowout nozzle 53 is integrally provided with a spherical shaft portion 56 that is pivotally supported by a spherical shell-shaped socket 55 at the upper end of the second passage 42 and a nozzle cylinder 57 that is formed in an upwardly expanding taper shape. By tilting the nozzle cylinder 57, the opening of the nozzle cylinder 57 can be directed in an arbitrary direction around the central axis of the second passage 42. The dropper resistor 50 described above is disposed inside the second passage 42 to cool the dropper resistor 50 with pressurized air passing through the second passage 42. In other words, with the pressurized air passing through the second passage 42 heated by the heat of the dropper resistor 50 to reduce the relative humidity of the pressurized air, the inside of the second passage on the leeward side of the dropper resistor 49 It is fed to the ion species generator 54 provided.

  The ion species generating unit 54 includes a cylindrical holder 60 made of plastic, a needle-like discharge electrode 61 disposed at the center of the interior of the holder 60, and a ring-shaped counter electrode 62 disposed around the holder 60. And the dielectric cylinder 63 etc. which insulates the space between both the electrodes 61 and 62. The discharge electrode 61 is connected to a drive circuit (not shown) that supplies a high-voltage pulse current, and the counter electrode 62 is connected to the ground lead of the drive circuit. When a pulse current is supplied between the discharge electrode 61 and the counter electrode 62, electrons are emitted from the discharge electrode 61 by corona discharge. The emitted electrons are combined with oxygen molecules in the air to become ionic species (negatively charged or positively charged molecular species). A combination of the ionic species and water molecules is an ion, and the ionic species and ions are released from the blowing nozzle 53. When the opening of the blowing nozzle 53 is directed toward the mist discharge section 27, the ionic species are brought into contact with the warm mist or cold mist discharged from the mist discharge section 27, and each mist is charged to a negative potential or a positive potential. It can be done.

  In the relationship between the first passage 41 and the second passage 42, the passage sectional area of the first passage 41 is set larger than the passage sectional area of the second passage 42. As a result, more air can be fed to the side of the mist feeding path 3 than the side of the ion species generation unit 54, and the amount of low-temperature mist can be increased. The above-described configuration is useful because the amount of mist blown out does not extremely decrease when the mist feed path 3 has the heating section 4 having a large air resistance.

  The mist inlet part 21, the mist outlet part 22, and the heating chamber 23 that constitute the mist feed path 3 are configured as follows. As shown in FIG. 5, the length H of the heating body K in the ventilation direction in the heating unit 4 is set larger than the length W of the heating body K in the direction orthogonal to the ventilation direction. Thus, by setting the length H to be larger than the length W, the contact time between the cold mist passing through the heating unit 4 and the heating body K is extended, and the heat transfer rib 33 is heated directly or indirectly Thus, it is possible to generate a warm mist with no temperature unevenness. That is, as the length H is set to be large, the heat transfer opportunity of the cold mist and the PTC heater 30 and the heat transfer block 31 can be increased to generate warm mist having a uniform temperature. In addition, since the PTC heater 30 is used as a heat source, the heater temperature does not rise more than necessary, and it is advantageous in terms of excellent safety when considering that warm mist is applied to the face skin and the like.

  As shown in FIG. 2, the cross-sectional area S1 of the virtual space occupied by the PTC heater 30 and the heat transfer block 31 in the heating chamber 23 (two-dot chain line in FIG. 2) is the cross-sectional area S of the heating chamber 23 (one point in FIG. 2). The chance of contact between the cold mist passing through the heating unit 4 and the heat transfer block 31 is increased so as to occupy more than half of the chain line). In this embodiment, the size of the virtual space occupied by the PTC heater 30 and the heat transfer block 31 is slightly smaller than the cross-sectional area S of the heating chamber 23, and the heating of the cold mist by the heat transfer block 31 having a large heat capacity Can be done effectively. The virtual space occupied by the PTC heater 30 and the heat transfer block 31 means the sum of the space occupied by the PTC heater 30 and the D-shaped space occupied by the heat transfer block 31.

  With regard to the relationship between the mist inlet 21 and the heating chamber 23, the diameter D2 of the inlet passage 24 at the mist inlet 21 is smaller than the diameter D1 of the inner surface of the heating chamber 23, and the cross-sectional area S2 of the inlet 24 is set. The cross-sectional area S of the heating chamber 23 was set smaller. Thus, by forming the inlet passage 24 so as to satisfy the inequality (S2 <S), the flow velocity of the air flow and the cold mist flowing from the mist inlet 21 to the heating chamber 23 is greatly reduced, The residence time in the heating chamber 23 can be prolonged. In addition, the air flow and the cold mist which have flowed to the heating chamber 23 can be made to flow along the base wall 32 whose temperature is higher than the tip of the heat transfer rib 33. Therefore, the cold mist and the air flow can be effectively heated by the PTC heater 30 and the heat transfer block 31, and the warm mist in the state without temperature unevenness can be generated.

  Regarding the relationship structure of the mist outlet 22 and the mist inlet 21, the diameter D3 of the outlet passage 26 at the mist outlet 22 is set larger than the diameter D2 of the inlet 24 at the mist inlet 21, and the outlet 26 is Is set to be larger than the cross-sectional area S2 of the inlet passage 24. In this way, by forming the outlet passage 26 so as to satisfy the inequality (S2 <S3), the flow rate of the warm mist immediately after being heated in the heating chamber 23 is changed to the flow rate of the cold mist passing through the inlet passage 24. The temperature is lowered from the speed, and the warm mist discharged from the mist discharge unit 27 is prevented from being vigorously blown to the face skin etc., so that the user does not feel hot.

  The relationship between the cross-sectional area S2 of the inlet passage 24, the cross-sectional area S3 of the outlet passage 26, and the cross-sectional area S of the heating chamber 23 is formed to satisfy the inequality (S2 <S3 <S). Thus, if the cross-sectional area S3 of the outlet passage 26 is made smaller than the cross-sectional area S of the heating chamber 23 while making the cross-sectional area S3 of the outlet passage 26 larger than the cross-sectional area S2 of the inlet passage 24, the flow rate of warm mist at the mist outlet 22 is It is possible to prevent the hot mist from adhering to the inner surface of the mist outlet portion 22 and causing condensation.

  The mist generator configured as described above can be operated in any one of the cold mist mode, the warm mist mode, and the alternate heating / cooling mode. For this purpose, the switch panel 5 has a power switch 66, A cold mist switch 67, a warm mist switch 68, and a warm mist switch 69 are provided. Below, the operation | movement condition of the mist generation | occurrence | production part 2, the heating part 4, the ventilation part 37, and the ion species generation part 54 is demonstrated for every operation mode.

(Cold mist mode)
When the cold mist mode 67 is selected by turning on the cold mist switch 67 after the power switch 66 is turned on, the ion species generating unit 54 is activated to release the ion species toward the blowing nozzle 53 as shown in FIG. To start. Further, simultaneously with the operation of the ion species generation unit 54, the mist generation unit 2 is operated to cause the vibration of the ultrasonic transducer 10 to act on the mist stock solution in the stock solution container 8 to generate cold mist. Further, when the ultrasonic transducer 10 is actuated and a predetermined time (0.5 seconds) elapses, the blower 37 is activated to deliver pressurized air into the stock solution container 8 and simultaneously into the second passage 42. To feed. The blower fan 38 at this time is rotationally driven at a high speed (Hi state) by the output Hi of the motor 39 and supplies a larger amount of pressurized air to the stock solution container 8 and the second passage 42 than in the warm mist mode.

  The cold mist generated in the stock solution container 8 is conveyed by the flowing pressurized air, passes through the mist introduction part 25 and the inlet passage 24, flows into the heating chamber 23, and is heated in the cold mist state. The fluid flows in the chamber 23 and is discharged from the mist discharging unit 27 of the mist outlet 22 to the outside of the case. By exposing the skin to the misty mass of the cold mist released, the skin can be moistened and moisturized. In addition, by cooling the face skin immediately after bathing with cold mist, it is possible to moisturize while suppressing the burning of the face skin. At this time, since the dropper resistor 50 is disposed in the second passage 42 and the heated air after cooling the same resistor 50 is discharged into the room, the pressurized air supplied from the first passage 41 to the mist generation unit 2 Can be prevented from being heated by the heat of the dropper resistor 50. As a result, compared with the case where the cold mist is heated by the heat of the dropper resistor 50, the cold mist having a lower temperature is released from the mist outlet 22 and the cold thermal stimulation is effectively exerted on the skin surface, Can reduce the burning of facial skin.

  The pressurized air supplied to the second passage 42 side is discharged from the blowout nozzle 53 together with the ion species generated in the ion species generation unit 54 to the outside of the case and combines with the water molecules contained in the air to be ionized. Do. At this time, since air having a low relative humidity after being heated by the heat of the dropper resistor 50 disposed in the second passage 42 is supplied to the ion species generation unit 54, the space between the discharge electrode 61 and the counter electrode 62 The generation of ionic species associated with the discharge can be activated. When the opening of the blowing nozzle 53 is directed toward the mist emitting unit 27, the cold mist discharged from the mist emitting unit 27 is brought into contact with the ionic species to charge the cold mist to a negative potential or a positive potential. And can supply charged cold mist to the skin surface of the face, neck and chest.

  When a predetermined time (10 minutes) elapses after the cold mist switch 67 is turned on, the operation of the mist generation unit 2 is stopped to stop the generation of the cold mist. Further, when a predetermined time (60 seconds) elapses after the mist generation unit 2 is stopped, the operation of the ion species generation unit 54 and the blower unit 37 is stopped, and generation of ion species and supply of pressurized air are stopped. . At the same time, the heating unit 4 operates for a predetermined time (60 seconds) to heat the heat transfer block 31 by the heat of the PTC heater 30, and cool mist or condensation adhering to the inner surface of the heat transfer block 31 or the heating chamber 23. The heat transfer block 31 and the heating chamber 23 are dried by evaporation. The output of the PTC heater 30 at the time of transpiration is made lower than the output of the warm mist generation state in the warm mist mode to be described later to prevent the overheat state in the mist feeding path 3. The time from when the cold mist switch 67 is turned on to when the PTC heater 30 stops operating is 12 minutes, but the cold mist switch 67 is turned on again as shown by the broken line in FIG. In this case, after the mist generating unit 2 stops operating, the operation of the ion species generating unit 54 and the air blowing unit 37 is stopped after a certain time has elapsed. Also in this case, the operation of the mist generating unit 2, the ion species generating unit 54, and the air blowing unit 37 is stopped at the time intervals described above. Finally, the PTC heater 30 is operated at a low output for a predetermined time to perform a drying process. As described above, after the operation of the mist generating unit 2 and the blower fan 38 is stopped, when the heating unit 4 is operated for a certain period of time, the mist in the mist feed path 3 is evaporated by the heat of the heating unit 4 to be dried. Can be promoted. Therefore, it is possible to eliminate the remaining of the mist in the mist feeding path 3 to prevent the proliferation of various bacteria, and to store the mist generator in a hygienic state. If the mist generating unit 2, the blower fan 38, and the heating unit 4 are stopped every time a predetermined time elapses in the order described, the generation of cold mist is stopped and then the compressed air is supplied by the blower fan 38. Thus, the inside of the mist feeding path 3 can be predried by the heated air. Furthermore, after the preliminary drying is completed, the heating unit 4 can be operated to reliably evaporate the mist remaining in the mist feeding path 3. That is, since the mist generating device can perform the storage preparation after use by itself, it is possible to reduce the time for maintenance by the user and to improve the usability of the mist generating device.

(Warm mist mode)
When the power mist switch 68 is turned on and then the temperature mist switch 68 is turned on to select the temperature mist mode, the ion species generator 54 operates to release the ion species toward the blowing nozzle 53 as shown in FIG. At the same time, the PTC heater 30 of the heating unit 4 is activated to heat the heat transfer block 31. When a predetermined time (5 seconds) elapses after the ion species generation unit 54 and the heating unit 4 start to operate, the mist generation unit 2 operates to vibrate the ultrasonic vibrator 10 with the mist stock solution in the stock solution container 8. Activate to produce a cold mist. Further, when the ultrasonic transducer 10 is actuated and a predetermined time (0.5 seconds) elapses, the blower 37 is activated to deliver pressurized air into the stock solution container 8 and simultaneously into the second passage 42. To feed. At this time, the output of the motor 39 becomes low, the blower fan 38 is driven to rotate at a low speed (Lo state), and a lower amount of compressed air is supplied to the stock solution container 8 and the second liquid at a lower pressure than in the cold mist mode. Feed to aisle 42

  As shown in FIG. 7, in the preheating state of the heating unit 4 from the ON operation of the warm mist switch 68 to the activation of the blower fan 38 of the blower unit 37, and after the blower fan 38 operates, The output of the PTC heater 30 when the heating unit 4 is in the warm mist generating state until the operation is stopped is set to be the same. This is for heating the heating unit 4 in a temperature state substantially the same as room temperature at an early stage so that a warm mist can be generated. The output of the preheating state can be set higher than the output of the heating unit 4 in the warm mist generation state in order to generate the warm mist more quickly. Moreover, the output of the heating unit 4 at the time of transpiration after the blower fan 38 is stopped is lower than the output of the heating unit 4 in the preliminary heating state or the warm mist generation state. This is to prevent the heating unit 4 already in a high temperature state from being overheated by stopping the blower fan 38 and to prevent the inside of the apparatus such as the mist feeding passage 3 from being overheated accordingly. Therefore, it is possible to evaporate the mist and the water in the mist feeding path 3 by the heat of the heating unit 4 while avoiding the overheating of the inside of the device and to promote the drying, and to prevent the proliferation of various bacteria.

  As described above, in the present embodiment, after a predetermined time has passed since the ion species generation unit 54 and the heating unit 4 are operated, the mist generation unit 2 is operated to operate the mist generation unit 2 for a predetermined time After the passage, since the blower fan 38 of the blower unit 37 is operated, the cold mist is released at the beginning of use when the switch is operated and used in the warm mist mode, giving the user a sense of discomfort. It can be prevented reliably. Further, when the heating unit 4, the mist generating unit 2 and the blower fan 38 are operated in the described order each time a predetermined time elapses, the heating unit 4 is heated to a sufficient temperature, and the generation amount of cold mist is sufficient The cold mist can be transported to the mist feed path 3 by the pressurized air and heated by the heating unit 4 only after reaching the point. That is, it is possible to accurately generate the warm mist in a state where all the preparation work is complete, and to release the warm mist from the start of use of the mist generating device. Therefore, the user does not have to confirm the release amount of the warm mist and the temperature condition one by one, and can process the skin surface and the like simultaneously with the release of the warm mist. In this example, after a predetermined time has elapsed since the ionic species generation unit 54 and the heating unit 4 were operated, the mist generation unit 2 was operated, and after a predetermined time had elapsed since the mist generation unit 2 was operated, The blower fan 38 of the blower unit 37 is actuated, but after a predetermined time has passed since the heating unit 4 is actuated, the ionic species generator 54, the mist generator 2 and the blower fan 38 are simultaneously actuated. Can be controlled. Also in this case, since the cold mist can be fed to the mist feeding path 3 after the heating unit 4 is sufficiently heated, cold mist is released at the beginning of use when the switch is operated and used in the warm mist mode. The user can be reliably prevented from feeling uncomfortable.

  The cold mist generated in the stock solution container 8 is transported by the flowing pressurized air, and flows into the heating chamber 23 through the mist introducing unit 25 and the inlet passage 24. The cold mist that has reached the inside of the heating chamber 23 comes into contact with the base wall 32 and the heat transfer rib 33 of the heat transfer block 31 having a large heat capacity, is heated by heat conduction action, and is further heated by the radiant heat of the heat transfer block 31. Part of the cold mist is directly heated by the heat of the PTC heater 30. Furthermore, while flowing while bypassing the upper and lower wedge members 28, the cold mist and the warm mist in the process of heating contact the base wall 32 and the heat transfer rib 33 and are heated. Accordingly, the cold mist is sufficiently heated while passing through the heating chamber 23 to become a warm mist, and is discharged from the mist outlet portion 22 to the outside of the case. The temperature of the warm mist at this time is 40 to 45 ° C. By exposing the face skin to the misty mass of the released warm mist, it is possible to increase the moisture of the skin surface while giving the face skin moisture. At this time, if the opening of the blowing nozzle 53 is directed toward the mist emitting section 27, the ionic species is brought into contact with the warm mist discharged from the mist emitting section 27, and the warm mist is set to a negative potential or a positive potential. It can be charged, and the charged warm mist can be supplied to the skin surface such as the face skin, neck, and chest.

  As shown in FIG. 7, the output of the motor 39 of the blower unit 37 in the warm mist mode is low, and the blower fan 38 is rotationally driven at a low speed. As a result, the moving speed of the cold mist is reduced compared to that in the warm mode, and the contact time of the cold mist passing through the heating unit 4 with the heating unit 4 becomes longer. Therefore, the cold mist can be uniformly heated, and the warm mist can be generated uniformly without temperature unevenness.

  The time from when the warm mist switch 68 is turned on to when the PTC heater 30 stops operating is 12 minutes, but the warm mist switch 68 is turned on again as shown by the broken line in FIG. In this case, the operation stop of the mist generation unit 2 and the operation stop of the ion species generation unit 54 and the blower unit 37 are performed at the same time intervals as in the cold mist mode, and further until the fixed time elapses. The heater 30 is operated to perform a drying process.

(Hot and cold alternate mode)
When the power switch 66 is turned on and then the warm / cool switch 69 is turned on to select the alternate heating / cooling mode, the ion species generator 54 is actuated as shown in FIG. At the same time, the PTC heater 30 of the heating unit 4 is activated to heat the heat transfer block 31. When a predetermined time (5 seconds) elapses after the ion species generation unit 54 and the heating unit 4 start to operate, the mist generation unit 2 operates to vibrate the ultrasonic vibrator 10 with the mist stock solution in the stock solution container 8. Activate to produce a cold mist. Further, when the ultrasonic transducer 10 is actuated and a predetermined time (0.5 seconds) elapses, the blower 37 is activated to deliver pressurized air into the stock solution container 8 and simultaneously into the second passage 42. To feed. At this time, the blower fan 38 is rotationally driven at a low speed (Lo state). In this state, since the cold mist is heated by the PTC heater 30 and the heat transfer block 31, the heated warm mist is discharged from the mist outlet 22 to the outside of the case.

  When 2 minutes have passed since the air blower 37 is activated, the operation of the PTC heater 30 is stopped, and at the same time, the air blower fan 38 is rotationally driven at a high speed (Hi state), and a large amount of pressurized air is supplied to the stock solution container 8 and the second container. 2 Feed to aisle 42 Therefore, the mist discharged from the mist outlet portion 22 becomes a cold mist. The supply of the cold mist is continuously performed for one minute after the PTC heater 30 stops operating, and when one minute elapses, the PTC heater 30 operates again to heat the heat transfer block 31, and at the same time, the blower fan 38 is simultaneously operated. Is driven to rotate at a low speed (Lo state) to generate warm mist and discharge it from the mist outlet 22. Thereafter, the generation of the warm mist is alternately performed for 2 minutes and the generation of the cold mist is alternately performed for 1 minute, and when the generation of the warm mist reaches the fourth time, the operation of the mist generation unit 2 is stopped and the ion species generation unit 54 And the operation stop of the ventilation part 37 is performed at the same time interval as the time of cold mist mode. Further, the heat transfer block 31 and the heating chamber 23 are dried while continuing the operation of the PTC heater 30 continuously to the last generation of the warm mist, and the total of 12 minutes of the cold alternate mode is completed. Do. As described above, in the heating / cooling alternate mode, the energized state of the PTC heater 30 is turned on / off at predetermined time intervals, and the rotational speed of the blower fan 38 is increased / decreased at predetermined time intervals to Supply alternately. If necessary, cold mist may be generated first.

  According to the mist generating apparatus configured as described above, the PTC heater 30 provided in the heating chamber 23 is used as a heat source to heat the mixture of cold mist and pressurized air in the heat transfer block 31 having a large heat capacity. Not only cold mist at normal temperature, but also sufficiently generated warm mist can be generated with certainty. Further, the pressurized air is used as a medium for transporting cold mist, and while the both pass through the heating chamber 23, the mixture of the cold mist and the pressurized air is forcibly heated by the PTC heater 30 and the heat transfer block 31. Therefore, unlike the conventional apparatus, it is possible to generate and discharge warm mist in a uniform temperature state.

  Further, in both cases of generating cold mist and warm mist, the mist generating unit 2 and the mist feeding path 3 are used in common, and the mist feeding path 3 is used only when the warm mist is generated. Since the provided heating unit 4 is operated, the overall structure of the mist generating device can be simplified and the manufacturing cost can be reduced as compared with the conventional device. Warm mist can be produced by boiling, that is, the mist stock solution can be heated by electric heating. In that case, hot water droplets and boiling droplets are generated by the bumping phenomenon, and the boiling droplets are released from the mist discharge part by steam pressure. There is a risk of safety. Moreover, since a long time is required until the mist undiluted solution is sufficiently heated and water vapor is generated, the response to mist generation tends to be slow. However, when the ultrasonic vibrator 10 generates cold mist, the ultrasonic vibrator 10 generates a cold mist within a short time when the ultrasonic vibrator 10 is operated, and a cold mist with a small heat capacity is further converted into a heat conductive material with a large heat capacity. Since the heat transfer block 31 made of aluminum is excellent in heat resistance, warm mist can be generated quickly and responsively. Since no hot water balls or boiling droplets are generated at the time of the formation of the cold mist, the safety can be remarkably improved as compared with the case where the warm mist is generated by heating the undiluted mist solution with electric heat.

  By adjusting the output of the PTC heater 30, the amount of heat when heating the cold mist can be adjusted, so the temperature of the warm mist can be freely changed as needed. Further, by changing the output state of the ultrasonic transducer 10, the amount of cold mist generated can be changed. Furthermore, since the particle size of the cold mist generated by the ultrasonic vibrator 10 or the centrifugal atomization method is smaller than the particle size of the warm mist generated by the boiling method and the heat capacity is small, the heating unit 4 can quickly heat the cold mist. To create a warm mist quickly. In order to operate the electrical components such as the PTC heater 30, the motor 39, and the ultrasonic transducer 10, a power supply unit that can output power of 30 to 50 W is required. By setting the power supply unit as an external structure, The main body case 1 can be made compact by avoiding enlargement.

  As shown in FIG. 1, when the anode electrode 35 and the cathode electrode 36 are immersed in tap water (mist stock solution) and a voltage of 10 to 20 volts is applied to both electrodes 35 and 36, the neutral region is caused by electrolysis. Chlorine-based electrolyzed water (hypochlorous acid-containing water) is produced. At this time, since hypochlorous acid is generated on the side of the anode electrode 35, a large amount of hypochlorous acid-containing water having a high concentration is present in the vicinity of the electrode 35. Therefore, the anode electrode 35 and the cathode electrode 36 are separated and arranged right and left immediately above the ultrasonic transducer 10, and the anode electrode 35 is disposed in the vicinity of the mist generating portion, so that the hypochlorous acid-containing water having a high concentration is misted. To produce a mist with a high bactericidal effect. More specifically, as shown in FIG. 1, the anode electrode 35 and the cathode electrode 36 are projected at positions other than just above the ultrasonic transducer 10 and in the axial direction (vertical direction) of the mist inlet 21. It arrange | positions so that it may be settled in the internal diameter of the mist inlet part 25 in vision. In FIG. 1, a part of the anode electrode 35 and the cathode electrode 36 overlap each other above the edge portion of the ultrasonic transducer 10, but in reality, a mist generating unit that swells the mist stock solution to generate mist. However, since it is not above the edge portion of the ultrasonic transducer 10, there is no particular problem in mist generation. In addition, since the obtained chlorine-based electrolyzed water has a bactericidal action, the inside of the tank can be bred. Furthermore, the chlorine-based electrolyzed water is misted and discharged from the mist discharger 27, whereby the air in the surrounding space where the mist device is installed can be disinfected.

  In the embodiment according to FIGS. 1 to 8, the wedging member 28 is integrally protruded from the inner surface of the heating chamber 23 toward the center of the chamber, and the wedging member 28 is a plate-like member in the direction orthogonal to the ventilation direction. It was made to be formed. However, the weir body 28 does not need to be orthogonal to the ventilation direction, and may be structured to be inclined at a large angle (for example, 45 degrees) as long as the structure is capable of retaining the cold mist and changing its flow direction. Good. That is, the plate-like barb member 28 may be disposed in a direction intersecting the ventilation direction. Further, the weir body 28 need not be provided integrally with the heating chamber 23, and may be formed as a separate independent part. Furthermore, the wedging body 28 may be formed integrally with the heat transfer rib 33. When the weir body 28 is arranged near the inner wall of the heating chamber 23, the cold mist passing through a portion far from the electric heating body 30 is guided to flow toward the electric heating body 30 arranged in the center of the heating chamber 23, It can be effectively heated.

  In the above embodiment, the virtual space sectional area S1 occupied by the PTC heater 30 and the heat transfer block 31 in the heating chamber 23 is slightly smaller than the sectional area S of the heating chamber 23, but this is not necessary. It is sufficient that the area S1 is at least half of the cross-sectional area S. For example, as shown in FIG. 9, when one heat transfer block 31 is disposed only on one side of the PTC heater 30, a total of the space occupied by the PTC heater 30 and the D-shaped space occupied by the heat transfer block 31. The cross-sectional area S1 (two-dot chain line in FIG. 9) may be at least half of the cross-sectional area S (one-dot chain line in FIG. 9) of the heating chamber 23.

  In addition, as shown in FIG. 10, when the heat source is composed of the PTC heater 30 and the heat transfer block 31 that are slightly smaller than the PTC heater 30 and the heat transfer block 31 described in the previous embodiment, the heat transfer block 31 is used. The two D-shaped spaces occupied by and the cross-sectional area S1 of the virtual space occupied by the PTC heater 30 (two-dot chain line in FIG. 10) are two of the cross-sectional area S of the heating chamber 23 (one-dot chain line in FIG. It is good if there is more than one minute. If the cross-sectional area S1 of the virtual space occupied by the PTC heater 30 and the heat transfer block 31 is less than half of the cross-sectional area S of the heating chamber 23, it is difficult to sufficiently heat the cold mist passing through the heating chamber 23. become. In addition, if the length of the heating chamber 23 in the ventilation direction is increased in order to make the heating temperature of the warm mist sufficient, the size of the mist generating device can not be avoided. The other parts are the same as in the previous embodiment, so the same reference numerals are given to the same members and the description thereof will be omitted. The same applies to the following embodiments.

  11 and 12 show still another embodiment of the heating unit. In this case, two insulating plates 72 are assembled in a cross shape, and the electrical heating elements 30 are arranged in a spiral along the winding grooves 73 formed stepwise in each of the insulating plates 72. Further, in this embodiment, the wedge members 28 are formed in a spiral shape, and disk-shaped wedge members 29 are disposed in a multistage manner in the central portion of the insulating plate 72 to cross each other. It was made possible to improve the contact opportunity. In this case, the electric heater 30 is provided with a waterproof function by applying an insulating silicon coating to the outer surface of the heater wire (nichrome wire), so that the adjacent heater coil is not short-circuited by mist. The heating element K provided in the heating section 4 in this embodiment comprises an insulating plate 72 assembled in a cross shape and an electric heater (heater wire) 30 wound around the insulating plate 72. In this embodiment, since the length H of the heating direction of the heating body K in the heating unit 4 is set larger than the length W of the heating body K in the direction perpendicular to the ventilation direction, the cold mist passing through the heating chamber 23 Can be heated by the electric heater 30 to reliably generate warm mist in a sufficient temperature state. In addition, the cross-sectional area S1 of the virtual space occupied by the heating body K (two-dot chain line in FIG. 12) is substantially the same as the cross-sectional area S of the heating chamber 23 (one-dot chain line in FIG. 12). As described above, the heating unit 4 in this embodiment is a part of the cold mist and the heating body K having the electric heating body 30 formed of a heater wire generating heat by electric power and the insulating plate 72 on which the electric heating body 30 is wound. And a barb 28 for changing the flow direction.

  FIG. 13 shows another embodiment of the mist generation unit. There, a cold mist was generated using a centrifugal atomization structure instead of ultrasonic vibration. The centrifugal atomization structure includes a conical pumping body 76 that is immersed in the mist stock solution, a rotating substrate 77 that is fixed to the upper end of the pumping body 76, and a group that is arranged in a multiple manner in the radial direction of the lower surface of the rotating substrate 77. And a motor 79 for rotationally driving the rotating substrate 77. When the motor 79 is activated, the pumping body 76 and the rotating substrate 77 are rotationally driven, and the mist stock solution crawls up from the immersion part along the surface of the pumping body 76 by the action of centrifugal force and flows to the lower surface of the rotating substrate 77. The mist stock solution that has reached the rotating substrate 77 is also subjected to centrifugal force and splashed in the radial direction, and repeatedly collides with the collision wall 78 on the lower surface of the rotating substrate 77 to become a fine cold mist. The generated cold mist is conveyed to the heating chamber 23 with the pressurized air fed into the stock solution container 8.

  According to the centrifugal atomization structure configured as described above, the amount of undiluted mist solution flowing from the pump body 76 toward the rotating substrate 77 is changed by changing the driving rotational speed of the motor 79 to a large or small size. The amount of cold mist that can be made can be increased or decreased. Therefore, for example, a large amount of cold mist can be generated in the cold mist mode, and the generation amount of cold mist can be set to be somewhat suppressed in the warm mist mode.

  14 and 15 show still another embodiment of the heating unit. In that case, the heating element K was formed by fixing the heat transfer block 31 made of aluminum to each of the front and rear surfaces of the electric heating element 30 by a Peltier element (thermoelectric conversion element). Of the pair of heat transfer blocks 31, one heat transfer block 31 is accommodated in the heating chamber 23, and the other heat transfer block 31 is exposed to the outside of the feeding cylinder 20. Reference numeral 82 denotes a holder for the electric heater 30 and is fixed to the cylindrical wall of the feeding cylindrical body 20.

  In the case of generating the warm mist, the cold mist passing through the heating chamber 23 is heated with the heat conducted to the heat transfer block 31 fixed to the heat radiating surface by supplying a driving current to the electric heating element 30 to warm the mist. Turn At this time, the heat transfer block 31 on the heat absorbing surface side outside the feed cylinder 20 releases cold heat. In the case of generating cold mist, a driving current having a reverse polarity is supplied to the electric heating body 30 so that the heating chamber 23 side is an endothermic surface, and the cold heat of the endothermic surface is transferred to the heat transfer block 31 in the heating chamber 23. Conduct. The cooled heat transfer block 31 can forcibly cool the cold mist in the heating chamber 23 to a temperature below room temperature. In addition, when it is not necessary to make the temperature of cold mist below room temperature, it is good to stop energization to the electric heating body 30. FIG.

  In this embodiment, the cross-sectional area S1 of the virtual space occupied by the heating body K (two-dotted chain line in FIG. 15) is substantially the same as the cross-sectional area S of the heating chamber 23 (one-dotted chain line in FIG. 15). The cross-sectional area S2 of the inlet passage 24, the cross-sectional area S3 of the outlet passage 26, and the cross-sectional area S of the heating chamber 23 are formed to satisfy the equation (S2 = S3 = S). The heat transfer block 31 disposed outside the feed cylinder 20 can be omitted. In that case, when the electric heating body 30 is energized, the heat transfer block 31 in the heating chamber 23 is heated to generate a warm mist, and when the energization to the electric heating body 30 is stopped, the cold mist can be fed. Let's do it.

  In addition to the above embodiment, the feeding cylinder 20 may be configured by a square cylinder, an oval cylinder, or the like, in addition to being formed in a cylindrical shape having a circular cross section. The mist introduction part 25 does not need to have a bell mouth structure, and may have a tapered cylindrical shape or a funnel shape that expands toward the mist generation part 2. If necessary, it may be configured in the form of a ventilating hood, as long as it is a structure capable of collecting and guiding cold mist toward the inlet passage 24. The heat transfer block 31 does not have to be formed in a heat sink shape, and can be formed, for example, by a block in which the inside of the round cylinder is formed in a honeycomb shape. The heater 30 may be arranged, or the heater wire 4 may be spirally wound around the round cylinder to form the heating unit 4. The heat transfer rib 33 described with reference to FIG. 2 can be inclined on a spiral other than being formed vertically. In that case, the surface area of the heat transfer rib 33 can be increased, and the contact opportunity and contact time of the cold mist and the heating body K can be further increased.

The mist generating apparatus of the said Example can be implemented with the following aspects.
Inside the main body case 1 are provided a mist generation unit 2 for forming a mist undiluted solution into mist, and a mist supply path 3 for guiding flow of cold mist generated by the mist generation unit 2,
The mist feeding path 3 is formed from the mist inlet 21 facing the mist generating unit 2 to the mist outlet 22 facing the outer surface of the main body case 1,
A mist generating device characterized in that a heating unit 4 for heating cold mist is provided in the mist feed path 3.
As described above, the heating unit 4 is provided in the mist feeding path 3 and the cold mist in the mist feeding path 3 is directly heated by the heating unit 4, so that the heat capacity that is finely misted by the heating air having a small heat capacity is large. Compared with the conventional apparatus which heats steam, the heating of cold mist can be performed reliably and a warm mist can be produced | generated effectively. Therefore, it is possible to provide a mist generator that can effectively generate cold mist and warm mist, respectively. Further, in both cases of generating cold mist and warm mist, the mist generating unit 2 and the mist feeding path 3 are used in common, and the mist feeding path 3 is used only when the warm mist is generated. Since the heating unit 4 provided is operated, the entire structure of the mist generating device can be simplified and the manufacturing cost can be reduced, as compared with the conventional device in which the spray device and the steam generating device need to be provided separately. There is also an advantage that the mist generator can be miniaturized as much as the overall structure is simplified.

In the above aspect,
The heating unit 4 includes a heating body K including an electric heating body 30,
The mist feed path 3 is provided with a heating chamber 23 that accommodates the heating element K,
The mist generator which the cross-sectional area S1 of the virtual space which the heating body K occupies in the heating chamber 23 occupies half or more of the cross-sectional area S of the heating chamber 23. FIG.
As described above, according to the heating unit 4 including the heating body K including the electric heater 30, the cold mist in the mist feeding path 3 can be heated in a short time. Further, in the heating chamber 23, the cross-sectional area S <b> 1 of the virtual space occupied by the heating body K occupies more than half of the cross-sectional area S of the heating chamber 23, thereby providing a heat transfer opportunity between the cold mist and the heating body K. Further, it is possible to uniformly generate a warm mist with no temperature unevenness.

In the above aspect,
The mist generating device in which the length H of the ventilation direction of the heating body K in the heating part 4 is set larger than the length W of the heating body K in the direction orthogonal to the ventilation direction.
As described above, when the length H of the heating body K in the aeration direction is set larger than the length W of the heating body K in the direction perpendicular to the aeration direction, the heating portion 4 is set as much as the length H is set large. The contact time between the cold mist and the heating body K passing through can be extended to increase the heat transfer opportunity of the cold mist and the heating body K, and the warm mist of uniform temperature can be generated more reliably.

In the above aspect,
A weir body 28 that changes the flow direction of the cold mist is provided on the inner surface of the heating chamber 23.
The mist generating apparatus which receives the cold mist which passes the heating chamber 23 by the cage | basket body 28, and the contact opportunity of cold mist and the heating body K is increased.
Thus, when the weir stopper 28 for changing the flow direction of the cold mist is provided on the inner surface of the heating chamber 23, a part of the cold mist passing through the heating member K is weired by the weir stopper 28, The flow direction of the warm mist on the way can be changed, and the flow rate can be further reduced to increase the heat transfer opportunity with the heating element K. Therefore, the cold mist passing through the heating unit 4 can be more reliably heated, and a warm mist with no temperature unevenness can be accurately generated.

In the above aspect,
A mist generating device in which the cross-sectional area S2 of the inlet passage 24 at the mist inlet 21 of the mist feeding passage 3 is set smaller than the cross-sectional area S of the heating chamber 23.
Thus, if the cross-sectional area S2 of the inlet passage 24 is set smaller than the cross-sectional area S of the heating chamber 23, the flow rate of the air flow and the cold mist flowing from the inlet passage 24 to the heating chamber 23 can be greatly reduced. it can. Further, the air flow and the cold mist flowing to the heating chamber 23 are made to flow along the center of the heating body K so that the heating of the cold mist and the air flow by the heating body K can be effectively performed. It is possible to generate warm mist in the absence state.

In the above aspect,
A mist generating device in which the cross-sectional area S3 of the outlet passage 22 at the mist outlet 22 of the mist feeding passage 3 is set larger than the cross-sectional area S2 of the inlet passage 24 at the mist inlet 21.
Thus, when the cross-sectional area S3 of the outlet passage 22 of the mist outlet portion 22 is set larger than the cross-sectional area S2 of the inlet passage 24 in the mist inlet portion 21, the flow rate of the warm mist immediately after being heated in the heating chamber 23 is set. The flow rate of the cold mist passing through the inlet passage 24 can be lowered. Therefore, the penetration degree in the air of the warm mist discharged from the mist outlet 22 can be alleviated, so that the warm mist discharged from the mist outlet 22 can be prevented from being vigorously sprayed on the face skin etc. The user who touched the hot mist can eliminate the hot feelings.

In the above aspect,
The cross section S2 of the inlet passage 24 in the mist inlet section 21, the cross section S3 of the outlet passage 26 in the mist outlet section 22, and the cross section S of the heating chamber 23 satisfy the inequality (S2 <S3 <S). Mist generator set to
Thus, the relationship among the cross-sectional area S2 of the inlet passage 24, the cross-sectional area S3 of the outlet passage 26, and the cross-sectional area S of the heating chamber 23 is set to satisfy the inequality (S2 <S3 <S). Then, while making the flow velocity of the warm mist at the mist outlet 22 smaller than the flow velocity of the mist inlet 21, make the warm mist larger than the flow velocity of the cold mist or the warm mist in the heating chamber 23. Can be prevented from adhering to the inner surface of the Therefore, most of the warm mist generated in the heating chamber 23 can be effectively discharged out of the main body case 1.

In the above aspect,
A mist generating device in which a mist introducing unit 25 is formed in the mist inlet 21 so as to gradually spread from the inlet passage 24 toward the mist generating unit 2.
As described above, when the expanded mist introduction portion 25 is formed in the mist inlet portion 21, the cold mist generated in the mist generation portion 2 is flow-guided and concentrated by the mist introduction portion 25, and then continuous to the mist introduction portion 25. Can be fed from the inlet passage 24 to the heating chamber 23. At this time, since the cold mist having passed through the inlet passage 24 flows toward the center of the heating body K, the heating of the cold mist in the heating chamber 23 can be performed more accurately.

  In the above embodiment, the air volume in the cold mist mode and the air volume in the warm mist mode are made different by changing the rotational speed of the blower fan 38. However, the present invention is not limited to this. The wind tunnel case 40A is provided with a valve capable of adjusting the passage area and a drive unit such as a motor for driving the valve, the passage area is narrowed in the warm mist mode, and the passage area is enlarged in the cold mist mode. The air volume in the mist mode and the air volume in the warm mist mode can be made to differ in size. In this embodiment, the rotational speed of the blower fan 38 is set to be the same in the warm mist mode and the cold mist mode.

  The cold mist is not limited to the room temperature, and is included in the concept of cold mist as long as it is lower than the heated warm mist. For example, even if it is physically warm, it is included in the cold mist. In other words, cold mist heated to a temperature lower than warm mist is also included in the concept of cold mist, without limiting the electric heat source 30 of the heating unit 4 completely without turning it off. In addition, after the electric heat source 30 of the heating unit 4 is completely turned off, a cold mist cooled to a temperature lower than normal temperature by a Peltier element (thermoelectric conversion element) provided in the mist feed path 3 is also a cold mist. Shall be included in the concept of

  In the above embodiment, the mist feeding passage 3 is formed by the feeding cylinder 20 composed of the front and rear divided cylinders, and the air passage 40 on the rear side of the feeding cylinder 20 accommodates the blower fan 38 and the motor 39. Although it is formed by the wind tunnel case 40A, it can be configured by a continuous cylindrical feeding body in which the feeding cylinder 20 and the wind tunnel case 40A are integrally formed. A configuration in which the heating unit 4, the mist generating unit 2, the motor 39 and the blower fan 38 are arranged in the order of description from the mist outlet unit 22 to the outside air intake unit (wind tunnel unit 43) is adopted in the continuous cylindrical feeder. It can also be done. In this case, the mist generating part 2 shall unitize an ultrasonic element and a tank, and shall mount | wear with this from the side part of a feed body so that attachment or detachment is possible.
