  (Example) FIG. 1 thru | or FIG. 8 shows the Example of the mist generator based on this invention. In the present invention, front / rear, left / right, and upper / lower follow the cross arrows shown in FIG. 1 and FIG. In FIG. 1, the mist generating apparatus has a hollow box-shaped main body case 1 in which a mist generating unit 2 that mists a mist stock solution and a mist feed that flows and guides cold mist generated in the mist generating unit 2. The supply path 3 and the heating unit 4 for heating the cold mist in the mist feed path 3 to form a warm mist are arranged. The upper surface of the main body case 1 is inclined downward toward the front surface, and the switch panel 5 is disposed below the upper surface.

  The mist generating unit 2 includes a stock solution container 8 for storing a mist stock solution, a tank 9 for replenishing the stock solution container 8 with a mist stock solution, an ultrasonic transducer 10 disposed on the bottom surface of the stock solution container 8, and the like. The stock solution container 8 is provided with a replenishing port 11 for mounting the tank 9 and a mounting port 12 for mounting a feed cylinder 20 to be described later, and for introducing pressurized air to the rear surface of the container. The air inlet 13 is open. A liquid level adjustment valve 14 is provided at the lower end of the tank 9 to keep the liquid level in the stock solution container 8 constant, and a cap 15 for opening and closing the replenishing port is attached to the upper end of the tank 9. The tank 9 can be removed from the stock solution container 8 and taken out of the main body case 1 by raising the switch panel 5 described above. The ultrasonic vibrator 10 is a commercially available product that uses a disk-shaped piezoelectric ceramic as a vibration source. By applying a high-frequency AC voltage, the mist stock solution in the stock solution container 8 is vibrated into a fine mist. The ultrasonic transducer 10 is fixed to the tank bottom wall with its upper surface facing the excitation window 16 opened at the bottom surface of the stock solution container 8. Reference numeral 17 is a seal rubber for sealing the periphery of the ultrasonic transducer 10.

  The mist feed path 3 is formed by a feed cylinder 20 composed of front and rear divided cylinders, and the cold mist generated by the ultrasonic vibrator 10 is generated by the flowing action of 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 in the mounting port 12 of the stock solution container 8, the mist inlet portion 21 is located inside the stock solution container 8 and faces the liquid surface directly above the ultrasonic transducer 10. The mist outlet portion 22 is exposed on the outer surface of the case at the upper part of the inclined wall on the upper surface of the main body case 1. That is, the mist inlet portion 21 faces the mist generating portion 2 inside the stock solution container 8.

  The mist inlet portion 21 includes an inlet passage 24 continuous to the lower portion of the heating chamber 23 and a bell mouth-like mist inlet portion 25 that gradually expands 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. The peripheral wall of the heating chamber 23 is formed in a round cylindrical shape, and a group of damming bodies 28 are provided above and below the inner surface. The weir body 28 is provided to increase the chance of contact between the cold mist passing through the heating chamber 23 and the heat transfer block 31 described later. As described above, when the bell mouth-like mist introducing portion 25 is formed in the mist inlet portion 21, the cold mist generated by the ultrasonic vibrator 10 is reliably introduced into the mist inlet portion 21 together with the pressurized air, and heated. It can be fed into the chamber 23. Therefore, the cold mist generated by the ultrasonic transducer 10 is prevented from being filled into the stock solution container 8 and condensed and flowing down, and all of the generated cold mist can be effectively utilized.

  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 arrange | positioned in the center part of the round cylindrical heating chamber 23, and the heat-transfer block 31 is arrange | positioned at the front-and-back surface. The heat transfer block 31 includes a base wall 32 that is in close contact with the PTC heater 30 that is disposed adjacent to the upper and lower sides, and seven heat transfer ribs 33 that protrude in parallel from the wall 32 toward the inner 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 damming body 28 described above is engaged with the heat transfer ribs 33 adjacent to the left and right to protrude into the heat transfer passage 34, and by blocking a part of the cold mist with the upper and lower damming bodies 28, The flow direction of the cold mist is changed and the flow rate is further lowered to increase the chance of contact with the heat transfer ribs 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. And can be supported in a stable state. 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 includes the electric heating element 30 that generates heat by the electric power, the heating element K having the heat transfer block 31 that dissipates the heat of the electric heating element 30 and heats the cold mist, and a part of the cold mist. It is comprised with the weir 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 fluidly guides the airflow pressurized by the blower fan 38, and the like Consists of. The air passage 40 includes a first passage 41 that feeds and guides a pressurized air flow toward the stock container 8 and a second passage that feeds and guides the pressurized air flow toward 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 1st channel | path 41, the 2nd channel | path 42, and the wind tunnel part 43 are formed by the wind tunnel case 40A which branches in two. That is, the air passage 40 is formed by a wind tunnel case 40 </ b> A that houses 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. Thus, the fluid flows from the mist inlet 21 into the mist feed path 3. The motor 39 is rotationally driven by a 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 AC 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, and the dropper resistor 50 is cooled by pressurized air passing through the second passage 42. In other words, in a state where the pressurized air passing through the second passage 42 is heated by the heat of the dropper resistor 50 and the relative humidity of the pressurized air is reduced, the compressed air passes into 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 generator 54 includes a cylindrical plastic holder 60, a needle-like discharge electrode 61 disposed in the center of the holder 60, and a ring-shaped counter electrode 62 disposed around the holder 60. And a dielectric cylinder 63 that insulates the space between 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. Can be made.

  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 supplied to the mist supply path 3 side than to the ionic species generation unit 54 side, and the amount of blowout 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 4 in the ventilation direction of the heating body K is set to be 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 greater than the length W, the contact time between the cold mist passing through the heating unit 4 and the heating body K is prolonged, and the heat transfer rib 33 is used to heat directly or indirectly. Thus, it is possible to generate a warm mist with no temperature unevenness. That is, the heat mist of the cold mist and the PTC heater 30 and the heat transfer block 31 can be increased by the amount that the length H is set to be large, and a warm mist with a uniform temperature can be generated. Moreover, since the PTC heater 30 is used as a heat source, the heater temperature does not rise more than necessary, and considering that the warm mist is applied to the facial skin and the like, it is advantageous in terms of excellent safety.

  As shown in FIG. 2, the cross-sectional area S1 (two-dot chain line in FIG. 2) of the virtual space occupied by the PTC heater 30 and the heat transfer block 31 in the heating chamber 23 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 so that the cold mist is heated 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.

  Regarding the structure of the relationship between the mist inlet 21 and the heating chamber 23, the diameter dimension D2 of the inlet passage 24 in the mist inlet 21 is made smaller than the diameter dimension D1 of the inner surface of the heating chamber 23, and the sectional area S2 of the inlet passage 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 rate of the air flow and the cold mist flowing from the mist inlet portion 21 to the heating chamber 23 is greatly reduced, The residence time in the heating chamber 23 can be prolonged. Further, the air flow and the cold mist that have flowed to the heating chamber 23 can be made to flow along the base wall 32, which has a higher temperature than the tips of the heat transfer ribs 33. Therefore, it is possible to effectively heat the cold mist and the air flow by the PTC heater 30 and the heat transfer block 31, and it is possible to generate a warm mist without temperature unevenness.

  Regarding the relationship structure between the mist outlet portion 22 and the mist inlet portion 21, the diameter dimension D3 of the outlet passage 26 in the mist outlet portion 22 is set larger than the diameter dimension D2 of the inlet passage 24 in the mist inlet portion 21, and the outlet passage 26 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. By reducing the speed, the hot mist discharged from the mist discharge unit 27 is prevented from being blown onto the face skin and the like, 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 so as to satisfy the inequality (S2 <S3 <S). Thus, when the sectional area S3 of the outlet passage 26 is made larger than the sectional area S2 of the heating chamber 23 while being larger than the sectional area S2 of the inlet passage 24, the flow rate of the warm mist at the mist outlet portion 22 is increased. 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 / cool 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, the mist generating unit 2 operates simultaneously with the operation of the ion species generating unit 54, and the vibration of the ultrasonic vibrator 10 is applied to the mist stock solution in the stock solution container 8 to generate cold mist. Further, when a certain time (0.5 seconds) elapses after the ultrasonic transducer 10 is activated, the air blowing unit 37 is activated to supply pressurized air into the stock solution container 8 and simultaneously into the second passage 42. To send. 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 through the chamber 23 and is discharged from the mist discharge part 27 of the mist outlet part 22 to the outside of the case. By exposing the facial skin to the mist mass of the released cold mist, the facial skin can be moistened and moistened. 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 is discharged into the room after the resistor 50 is cooled, the pressurized air supplied from the first passage 41 to the mist generating unit 2. Can be prevented from being heated by the heat of the dropper resistor 50. Thereby, compared with the case where the cold mist is heated by the heat of the dropper resistance 50, the cold mist having a lower temperature is discharged from the mist outlet portion 22, and the cold stimulation is effectively applied to the skin surface. Can reduce the burning of facial skin.

  The pressurized air supplied to the second passage 42 side is discharged from the blow nozzle 53 together with the ionic species generated by the ionic species generator 54, and is ionized by being combined with water molecules contained in the air. To 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 ionic species generator 54, the discharge electrode 61 and the counter electrode 62 are 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. It is possible to supply charged cold mist to the skin surface such as the facial skin, neck, and chest.

  When a certain time (10 minutes) elapses after the cold mist switch 67 is turned on, the operation of the mist generating unit 2 is stopped and the generation of the cold mist is stopped. When a certain time (60 seconds) elapses after the mist generating unit 2 is stopped, the operation of the ion species generating unit 54 and the air blowing unit 37 is stopped, and the generation of the ion species and the supply of pressurized air are stopped. . At the same time, the heating unit 4 operates for a certain time (60 seconds), heats the heat transfer block 31 with the heat of the PTC heater 30, and removes cold mist and dew condensation adhering to the inner surface of the heat transfer block 31 and 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 lower than the output in the warm mist generation state in the warm mist mode to be described later to prevent an overheating state in the mist feed 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 prevent the mist from remaining in the mist feed path 3 and prevent the propagation of germs, and the mist generating device can be stored 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 feed path 3 can be preliminarily dried with 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 feed path 3. In other words, since the mist generating device can prepare for storage after use, it is possible to reduce the user's care and 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 certain time (5 seconds) elapses after the ionic species generation unit 54 and the heating unit 4 start to operate, the mist generation unit 2 operates, and vibration of the ultrasonic vibrator 10 is applied to the mist stock solution in the stock solution container 8. Cold mist is generated by acting. Further, when a certain time (0.5 seconds) elapses after the ultrasonic transducer 10 is activated, the air blowing unit 37 is activated to supply pressurized air into the stock solution container 8 and simultaneously into the second passage 42. To send. 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 passage 42.

  As shown in FIG. 7, when the heating unit 4 is in a preheating state from when the warm mist switch 68 is turned on until the blower fan 38 of the blower unit 37 is activated, and after the blower fan 38 is activated, 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. In order to make it possible to generate the warm mist earlier, the output in the preheating state can be set higher than the output of the heating unit 4 in the warm mist generating state. Moreover, the output of the heating part 4 at the time of transpiration after the blower fan 38 stops is made lower than the output of the heating part 4 in the preheating state or the warm mist generation state. This is to prevent the heating unit 4 that is already in a high temperature state from being overheated by stopping the blower fan 38, and accompanying this, the inside of the apparatus such as the mist feed path 3 is not overheated. Therefore, drying can be promoted by evaporating the mist and water in the mist feed path 3 with the heat of the heating unit 4 while avoiding the inside of the apparatus from being overheated, and propagation of germs can be prevented.

  As described above, in this embodiment, after a predetermined time has passed since the ionic species generation unit 54 and the heating unit 4 are operated, the mist generation unit 2 is operated, and the mist generation unit 2 is operated for a predetermined time. After the passage, since the blower fan 38 of the blower unit 37 is activated, when the switch is operated and used in the warm mist mode, the cold mist is released at the beginning of use, which causes discomfort to the user. It can be surely prevented. Further, when the heating unit 4, the mist generating unit 2 and the blower fan 38 are operated every time a predetermined time elapses in the order of description, the heating unit 4 is heated to a sufficient temperature, and a sufficient amount of cold mist is generated. 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, it is not necessary for the user to check the discharge amount or temperature state of the warm mist, and the skin surface can be processed at the same time as the warm mist is discharged. 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. It can also be controlled. Also in this case, since the cold mist can be fed to the mist feed path 3 after the heating unit 4 is sufficiently heated, the cold mist is released when the switch is operated and used in the warm mist mode. It is possible to reliably prevent the user from feeling uncomfortable.

  The cold mist generated in the stock solution container 8 is transported by the flowing pressurized air, passes through the mist introduction part 25 and the inlet passage 24 and flows into the heating chamber 23. 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. A part of the cold mist is directly heated by the heat of the PTC heater 30. Further, the cold mist and the warm mist in the middle of heating are heated in contact with the base wall 32 and the heat transfer rib 33 while flowing while bypassing the upper and lower weir bodies 28. 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 40-45 degreeC. By exposing the facial skin to the mist mass of the released warm mist, the moisture of the skin can be increased while moistening the facial skin. 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. Thereby, the moving speed of cold mist will fall compared with the time of temperature mode, and the contact time to the heating part 4 of the cold mist which passes the heating part 4 becomes long. Accordingly, the cold mist can be heated uniformly, and the warm mist can be uniformly generated 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 such a case, the operation stop of the mist generating unit 2 and the operation stop of the ionic species generating unit 54 and the air blowing unit 37 are performed at the same time interval as in the cold mist mode, and further, the PTC until a certain time elapses. The heater 30 is operated to perform a drying process.

(Alternating heating / cooling 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 certain time (5 seconds) elapses after the ionic species generation unit 54 and the heating unit 4 start to operate, the mist generation unit 2 operates, and vibration of the ultrasonic vibrator 10 is applied to the mist stock solution in the stock solution container 8. Cold mist is generated by acting. Further, when a certain time (0.5 seconds) elapses after the ultrasonic transducer 10 is activated, the air blowing unit 37 is activated to supply pressurized air into the stock solution container 8 and simultaneously into the second passage 42. To send. 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 portion 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 is fed to the passage 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 1 minute after the operation of the PTC heater 30 is stopped, and when 1 minute elapses, the PTC heater 30 is operated again to heat the heat transfer block 31 and at the same time the blower fan 38. Is rotated at a low speed (Lo state) to generate a 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 Further, the operation of the blower 37 is stopped at the same time interval as in the cold mist mode. Furthermore, after the last warm mist generation, the heat transfer block 31 and the heating chamber 23 are dried while the PTC heater 30 is in operation, and the warm / cool alternate mode for 12 minutes is completed. To 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 Are supplied alternately. If necessary, cold mist may be generated first.

  According to the mist generator configured as described above, the PTC heater 30 provided in the heating chamber 23 is used as a heat source, and the mixture of cold mist and pressurized air is heated by the heat transfer block 31 having a large heat capacity. Not only cold mist at room temperature, but also warm mist that has been sufficiently heated can be generated reliably. In addition, the compressed air is used as a cold mist carrier medium, and while both of them pass through the heating chamber 23, the PTC heater 30 and the heat transfer block 31 forcibly heat the mixture of the cold mist and the pressurized air. Therefore, unlike the conventional apparatus, it is possible to generate and release a warm mist having 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. Further, since it takes a long time for the mist stock solution to be sufficiently heated to generate water vapor, the response until the mist is generated 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 excellent in heating is used, a warm mist can be generated quickly and with good response. Since no hot water balls or boiling droplets are generated when the cold mist is generated, safety can be significantly improved as compared with the case where the mist stock solution is heated by electric heating to generate the warm mist.

  By adjusting the output of the PTC heater 30, the amount of heat when the cold mist is heated can be adjusted, so that the temperature of the warm mist can be freely changed as necessary. In addition, the amount of cold mist generated can be changed by changing the output state of the ultrasonic transducer 10. 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. The warm mist can be generated 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 an anode electrode 35 and a 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 generated by electrolysis. Chlorinated electrolyzed water (water containing hypochlorous acid) is produced. At this time, since hypochlorous acid is generated on the anode electrode 35 side, a large amount of hypochlorous acid-containing water having a high concentration exists 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 antibacterial effect. More specifically, as shown in FIG. 1, the anode electrode 35 and the cathode electrode 36 are projected at a position other than directly above the ultrasonic transducer 10 and in the axial direction (vertical direction) of the mist inlet 21. It is arranged so as to fit within the inner diameter of the mist inlet portion 25 when viewed. 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 generating mist. Moreover, since the obtained chlorinated electrolyzed water has an antibacterial action, it is possible to control the bacteria in the tank. Furthermore, sterilization of the air in the surrounding space where the mist device is installed can be performed by converting the chlorinated electrolyzed water into a mist and releasing it from the mist discharge section 27.

  In the embodiment according to FIGS. 1 to 8, the weir body 28 is integrally projected from the inner surface of the heating chamber 23 toward the center of the chamber so that the weir body 28 is a plate-like body in a direction orthogonal to the ventilation direction. 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 weir body 28 may be disposed in a direction intersecting with 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 weir 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 heated effectively.

  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 arranged only on one side of the PTC heater 30, the 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 cross-sectional area S1 (two-dot chain line in FIG. 10) of the two D-shaped spaces occupied by and the virtual space occupied by the PTC heater 30 is 2 of the cross-sectional area S (one-dot chain line in FIG. 10) of the heating chamber 23. It only needs to be 1 / min or more. 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. Further, 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, it is inevitable that the mist generating device is enlarged. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted. The same applies to the following embodiments.

  11 and 12 show still another embodiment of the heating unit. There, the two insulating plates 72 are assembled in a cross shape, and the electric heating elements 30 are arranged in a spiral shape along the winding grooves 73 formed in steps on the respective insulating plates 72. Further, in this embodiment, the damming body 28 is formed in a spiral shape, and the disk-shaped damming bodies 29 are arranged in multiple stages at the center of the intersecting insulating plates 72 so that the cold mist and the electric heating element 30 are arranged. 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. In this embodiment, the heating body K provided in the heating unit 4 includes an insulating plate 72 assembled in a cross shape and an electric heating body (heater wire) 30 wound around the insulating plate 72. In this embodiment, the length H in the ventilation 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 orthogonal to the ventilation direction, so that the cold mist passing through the heating chamber 23 Can be heated by the electric heating element 30 to reliably generate a warm mist in a sufficient temperature state. In addition, the cross-sectional area S1 (two-dot chain line in FIG. 12) of the virtual space occupied by the heating body K is made substantially the same as the cross-sectional area S (one-dot chain line in FIG. 12) of the heating chamber 23. As described above, the heating unit 4 in this embodiment includes the heating body K including the electric heating body 30 formed of a heater wire that generates heat by electric power and the insulating plate 72 around which the electric heating body 30 is wound, and a part of the cold mist. And a weir body 28 that changes the flow direction.

  FIG. 13 shows another embodiment of the mist generating 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. The collision wall 78 and the motor 79 that rotationally drives the rotary substrate 77 are included. 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 mist stock solution flowing from the pumping body 76 toward the rotating substrate 77 is changed by changing the drive rotation speed of the motor 79 to a larger or smaller value. The amount of cold mist that can be produced can be increased or decreased. Therefore, for example, a larger amount of cold mist can be generated in the cold mist mode, and the amount of cold mist generated can be set somewhat less in the warm mist mode.

  14 and 15 show still another embodiment of the heating unit. There, the electric heating element 30 was constituted by Peltier elements (thermoelectric conversion elements), and the heating element K was constituted by fixing aluminum heat transfer blocks 31 on the front and rear surfaces thereof. 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 outside the feed cylinder 20. Reference numeral 82 denotes a holder for the electric heating body 30, which is fixed to the cylinder wall of the feeding cylinder 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 into. At this time, the heat transfer block 31 on the side of the heat absorption surface outside the feed cylinder 20 releases cold. 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 (two-dot chain line in FIG. 15) of the virtual space occupied by the heating element K is made substantially the same as the cross-sectional area S (one-dot chain line in FIG. 15) of the heating chamber 23. Further, 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 were formed so as 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. Like that.

  In addition to the above-described embodiment, the feeding cylinder 20 may be formed of a square cylinder or an elliptic cylinder other than 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 shape of a ventilation hood. In short, any structure that can collect and guide the cold mist toward the inlet passage 24 may be used. The heat transfer block 31 does not need to be formed in a heat sink shape. For example, the heat transfer block 31 can be formed by a block in which the inside of the round tube is formed in a honeycomb shape. In this case, PTC is formed at a plurality of locations on the peripheral surface of the round tube. 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 in addition to 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.
A mist generating section 2 that mists the mist stock solution and a mist feed path 3 that flows and guides the cold mist generated by the mist generating section 2 are provided in the body case 1.
The mist feed path 3 is formed from the mist inlet part 21 facing the mist generating part 2 to the mist outlet part 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 the warm mist can be 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 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 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 embodiment,
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,
A mist generator in which the cross-sectional area S1 of the virtual space occupied by the heating body K in the heating chamber 23 occupies more than half of the cross-sectional area S of the heating chamber 23.
Thus, according to the heating part 4 provided with the heating body K containing the electric heating body 30, the cold mist in the mist feed 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. Further, it is possible to uniformly generate a warm mist with no temperature unevenness.

In the above embodiment,
A mist generating apparatus in which the length H of the heating body K in the ventilation direction of the heating unit 4 is set to be larger than the length W of the heating body K in a direction orthogonal to the ventilation direction.
Thus, if the length H of the heating body K in the ventilation direction is set to be larger than the length W of the heating body K in the direction orthogonal to the ventilation direction, the heating unit 4 is increased by the length H. By extending the contact time between the cold mist passing through the heating element K and the heating element K, the heat transfer opportunity between the cooling mist and the heating element K can be increased, and a warm mist with a uniform temperature can be more reliably generated.

In the above embodiment,
A weir body 28 that changes the flow direction of the cold mist is provided on the inner surface of the heating chamber 23.
A mist generating apparatus in which the cold mist passing through the heating chamber 23 is received by the weir body 28 to increase the chance of contact between the cold mist and the heating body K.
When the weir body 28 that changes the flow direction of the cold mist is provided on the inner surface of the heating chamber 23 in this way, a part of the cold mist that passes through the heating body K is blocked by the weir body 28, and the cold mist and the heating 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 embodiment,
A mist generating device in which the cross-sectional area S2 of the inlet passage 24 in the mist inlet section 21 of the mist feeding path 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 that have flowed to the heating chamber 23 are caused to flow along the center of the heating body K, so that the cold mist and the air flow can be effectively heated by the heating body K. A warm mist can be generated in the absence of this.

In the above embodiment,
A mist generating device in which the cross-sectional area S3 of the outlet passage 22 in the mist outlet portion 22 of the mist feed path 3 is set larger than the cross-sectional area S2 of the inlet passage 24 in the mist inlet portion 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 of the warm mist discharged from the mist outlet portion 22 in the air can be eased, and the hot mist discharged from the mist outlet portion 22 can be prevented from being sprayed on the face skin and the like. The user who touched the hot mist can eliminate the hot feelings.

In the above embodiment,
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 do.
Thus, 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 set to satisfy the inequality (S2 <S3 <S). Then, while making the flow rate of the warm mist at the mist outlet portion 22 smaller than the flow rate of the mist inlet portion 21, it is made larger than the flow rate of the cold mist or warm mist in the heating chamber 23 so that the warm mist becomes the mist outlet portion 22. It is possible to prevent condensation from adhering to the inner surface. 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 embodiment,
A mist generating device in which a mist introducing portion 25 that gradually expands from the inlet passage 24 toward the mist generating portion 2 is formed in the mist inlet portion 21.
As described above, when the expanded mist introduction part 25 is formed at the mist inlet part 21, the cold mist generated by the mist generation part 2 is flow-guided and aggregated by the mist introduction part 25, and then continues to the mist introduction part 25. Can be fed from the inlet passage 24 to the heating chamber 23. At this time, since the cold mist that has passed through the inlet passage 24 flows toward the center of the heating body K, the cold mist in the heating chamber 23 can be heated 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. In the warm mist mode, the passage area is reduced, and in the cold mist mode, the passage area is enlarged to The air volume in the mist mode and the air volume in the warm mist mode can be made different. 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, the cold mist concept includes a cold mist that is heated to a temperature lower than the warm mist by limiting the electric heat source 30 of the heating unit 4 without completely 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. It is included in the concept of

  In the above embodiment, the mist feed path 3 is formed by the feed cylinder 20 composed of the front and rear divided cylinders, and the air passage 40 on the rear side of the feed cylinder 20 accommodates the blower fan 38 and the motor 39. The wind tunnel case 40A is formed by a continuous tubular feed body in which the feed cylinder body 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. You can also. 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.
