Therefore, the steam generated in the boiler chamber 37 is separated from the branch portion 42 and guided to the steam nozzles 21a and 21b through the first guide pipe 41a and the second guide pipe 41b. Since the pressure in the boiler chamber 37 and the steam guide pipe 41 is high, steam is discharged from the discharge holes of the steam nozzles 21a and 21b with a certain degree of momentum. Note that the inner diameters of the discharge holes of the steam nozzles 21a and 21b are set to 3.6 mm, for example.

  Further, a steam discharge portion 43 having a discharge electrode 43 a is provided at a position slightly before the branch portion 42 of the steam guide conduit 41. The steam discharge portion 43 is for further miniaturizing the steam passing through the discharge portion 43 by its own discharge.

Steam is branched. The inner diameter of the cylindrical portion 44a is set to, for example, 4.5 mm, which is larger than the inner diameter of the discharge holes of the steam nozzles 21a and 21b and 1.5 times or less the inner diameter of the discharge holes.

  The mist generating unit 32 is provided on the rear side of the steam generating unit 31 and generates a cold mist using the venturi effect. The water in the water supply pipe 19 extending from the water supply tank 18 is used not only as the steam generation but also as a cold mist, and a pipe member for feeding a part of the water from the water supply pipe 19 to the mist nozzle 22. The water supply pipeline 51 is provided. The water supply pipe 51 is a pipe arranged so as to meander (bend) three times in the plane (heat radiating surface) direction of the heat radiating surface (vertical surface) 36a of the rear PTC heater 36 and to come into contact with the heat radiating surface 36a. A contact pipe 51a as a path member is provided. The laminar flow of the liquid is suppressed in the contact pipe 51a by meandering the contact pipe 51a.

  As shown in FIG. 2, the contact pipe 51a of the water supply pipe 51 is pressed and fixed to the heat radiating surface 36a side by a separation preventing member RB so that the whole is not separated from the heat radiating surface 36a. Further, as shown in FIG. 2, the contact pipe 51 a of the water supply pipe 51 has an elliptical cross section in the radial direction, and the water supply pipe 51 is arranged in the plane (heat radiating surface) direction of the heat radiating surface 36 a of the PTC heater 36. They are arranged so that the longitudinal direction of the cross section (the vertical direction in FIG. 2) is along. A predetermined amount of water (for example, a larger amount of water than the amount of mist released during a predetermined course) is held inside the contact pipe 51a configured as described above, and the PTC heater 36 on the rear side at the time of the steam generation is retained. With this heat (residual heat), the water for cold mist is sterilized at 80 degrees for 30 seconds or more, for example. Therefore, the cold mist discharged from the mist nozzle 22 is maintained in a sanitary state suitable for beauty.

  Further, a filter 52 as a filtration mechanism is mounted in the pipe immediately before the mist nozzle 22 in the water supply pipe 51. This filter 52 is a mist of dirt, debris, debris generated in the water supply line 51 or the contact line 51a as a duct member, and dust or debris contained in the liquid (water) itself for generating mist. This prevents the mist nozzle 22 from clogging, so that the clogging of the mist nozzle 22 can be suppressed, so that the mist is stably discharged from the mist nozzle 22. Therefore, a mist can be comfortably applied to the user's skin (face) when using the apparatus 10 to enhance the beauty effect (skin care effect).

  Also, as the mist generating unit 32, a pneumatic feeding path 53 is provided in the facial body 12 and air is fed into the pneumatic feeding path 53 by the operation of a pump 54 using an electric motor as a drive source. Is called. This pumped air is supplied toward the discharge hole of the mist nozzle 22, and a venturi effect is produced by joining the water in the water supply pipe 51 before the discharge hole, and the water in the water supply pipe 51 is sucked out together with the pumped air. As a result, cold mist is generated and discharged.

  The negative ion production | generation part 33 is provided in the nozzle part 13 as shown in FIG.2 and FIG.4, generates a corona discharge, and produces | generates a negative ion. The ion generation unit 33 is configured such that a unitized negative ion discharge unit 61 is accommodated and held in an accommodation recess 23 a formed in the ion nozzle 23 of the nozzle unit 13. In the ion discharge portion 61, the needle electrode 63 is supported with respect to the electrode holder 62 having a predetermined shape so as to be accommodated and held in the accommodation recess 23a, and on the axis of the needle electrode 63 on the distal end side of the needle electrode 63. An annular counter electrode 64 is supported and configured so that the annular center is located. The needle electrode 63 and the counter electrode 64 are each connected to a control circuit board 71 in the vicinity of the upper surface of the facial body 12 through a lead wire 65 connected thereto and led out from the electrode holder 62.

  Incidentally, in this ion generation part 33 (ion discharge part 61), the space X2 around the needle electrode 63 is only opened to the outside, and the space X2 around the needle electrode 63 and the space X1 in the facial body 12 are partitioned. It has been. This is because, when a member using a silicon material (for example, a part of the water supply conduit 51) provided in the space X1 in the face body 12 is heated by a heat source such as the PTC heaters 35 and 36, the space X1 This is because if silicon floats and the floating silicon adheres to the needle electrode 63, corona discharge is hindered and the amount of negative ions generated is reduced, and adhesion of the floating silicon to the needle electrode 63 is prevented in advance. Yes.

  The control circuit board 71 is supplied with power from the outside by a power cord 70 (see FIG. 1), and based on the control of the control circuit 72 composed of various circuit components mounted on the board 71, the steam generation unit 31, Operation power is supplied to each of the mist generation unit 32 and the ion generation unit 33. As shown in FIG. 5, the control circuit 72 switches between the operable state and the stopped state of the facial device 10 based on the on / off operation of the power switch 25, and the operation control switch 26 and the course selection switch in the operable state. Based on the setting of various use courses by 27 combination operations, the operation of the steam generating unit 31 (PTC heaters 35, 36, the steam discharge unit 43, etc.) and the mist generating unit 32 (pump 54, etc.) is controlled. In addition, the ion generation unit 33 (ion discharge unit 61) is operated together with the operations of the previous generation units 31 and 32. Therefore, the beauty effect by a negative ion and steam (warm mist) and the beauty effect by a negative ion and mist (cold mist) can be acquired.

  When a high voltage is applied to the needle electrode 63 during negative ion generation, a corona discharge is generated around the tip of the needle electrode 63 due to a potential difference with the counter electrode 64, and negative ions are generated. The generated negative ions are attracted to the counter electrode 64 having a potential lower than that of the needle electrode 63 and are discharged to the outside from the ion nozzle 23.

Next, characteristic effects of the present embodiment will be described.
(1) The mist generating unit 32 as a mist generating mechanism is provided with a function as a sterilizing mechanism for sterilizing a liquid that generates mist, and uses a residual heat of the PTC heater 36 as a heating device for generating steam to sterilize the mechanism. Is configured. That is, by using the PTC heater 36 that generates steam to constitute the sterilization mechanism, it is possible to sterilize the mist (liquid that generates mist) without the need to separately provide a heating device (heater) for sterilization, and the number of parts is increased. Therefore, the overall size of the apparatus 10 can be reduced.

  (2) The sterilization mechanism is configured so that the contact pipe 51a as the pipe member through which the liquid for generating mist flows and the PTC heater 36 (heat radiation surface 36a) as the heating device come into contact with each other. Thereby, since heat (residual heat) from the PTC heater 36 that generates steam is easily transmitted to the contact pipe line 51a side, the mist (liquid that generates mist) can be sterilized more suitably.

  (3) One or more contact pipes 51a meander (bend) in the surface direction of the heat radiating surface 36a of the PTC heater 36 to constitute a sterilization mechanism. Thereby, since the contact pipe 51a can be disposed relatively long in the surface direction of the heat dissipation surface 36a of the PTC heater 36, the surface area and volume of the contact pipe 51a increase in the surface direction of the heat dissipation surface 36a. Heat from the heater 36 can be efficiently received by the contact pipe 51a. Therefore, a large amount of liquid for generating sterilized mist can be stored.

  (4) The sterilization mechanism is configured such that the longitudinal direction of the cross section of the contact pipe 51a is along the plane (surface) direction of the heat radiation surface 36a of the PTC heater 36 (the vertical direction in FIG. 2). That is, the heat transmitted from the heat radiating surface 36a of the PTC heater 36 can be received in the longitudinal direction of the cross section of the contact pipe 51a by keeping the cross-sectional longitudinal direction of the contact pipe 51a in the plane direction of the heat radiating surface 36a. It is possible to efficiently transfer heat to the contact pipe 51a and the liquid for generating mist.

  (5) The sterilization mechanism is configured by providing the separation preventing member RB so that the contact pipe 51a is not separated from the PTC heater 36. Thereby, since the contact state in which the PTC heater 36 and the contact pipe 51a contact each other is stably maintained, the mist can be more stably heated and sterilized.

  (6) Since the water supply pipe 51 as the pipe line member is provided with the filter 52 as the filtration mechanism, it is possible to prevent the water scale, dust, debris and the like generated in the water supply pipe 51 from flowing into the mist nozzle 22. Thereby, since clogging of the mist nozzle 22 can be suppressed, the mist can be stably discharged. Moreover, it can also suppress that dust etc. flow in into the water supply pipe line 51 from the mist nozzle 22. Furthermore, since a filter 52 as a filtration mechanism is disposed immediately before the mist nozzle 22, it is possible to more suitably suppress water scale, dust, debris, and the like generated in the water supply pipe 51 from flowing into the mist nozzle 22. It becomes possible to discharge mist more stably.
