Thus, the water supply tank 36 is locked so as not to move relative to the tank holder 35.

  As shown in FIGS. 4 and 5, a discharge tube 41 extending from the lower portion of the tank holder 35 is connected to the drain port 32 shown in FIG. 2. A branch portion 42 is provided in the middle of the discharge tube 41, and an upstream end of a water supply tube 43 whose downstream side branches into a bifurcated shape is connected to the branch portion 42. Each downstream end of the water supply tube 43 is cooled by a steam generation mechanism 44 (see FIG. 6) that generates steam (warm mist) from the water supplied from the water supply tank 36 and from the water supplied from the water supply tank 36.

The steam generation mechanism 44 generates steam by boiling water supplied from the water supply tank 36 through the water supply tube 43 into the boiler chamber 47 inside the PTC heaters 46a and 46b.

  A steam guide pipe 48 for guiding the generated steam to the pair of steam nozzles 16a and 16b is connected to the upper portion of the boiler chamber 47. Therefore, the steam generated in the boiler chamber 47 is guided to the steam nozzles 16a and 16b through the steam guide pipes 48, respectively. Since the pressure in the boiler chamber 47 and the steam guide pipe 48 becomes high, steam is discharged from the discharge holes of the steam nozzles 16a and 16b with a certain degree of momentum. The inner diameter of the discharge holes of the steam nozzles 16a and 16b is set to 3.6 mm, for example.

  Further, a steam discharge portion 49 is provided in the middle of the steam guide pipe 48. The steam discharge part 49 makes the passing steam finer by its own discharge. In the steam discharge portion 49, a metal (for example, platinum) that has an anti-oxidation effect and is good for the skin is used, and the metal fine particles are generated by using discharge.

  As shown in FIG. 6, the cold mist generating mechanism 45 is disposed on the rear side of the steam generating mechanism 44, and generates a cold mist using the Venturi effect. Such a cold mist generating mechanism 45 includes a boiler block 60 that is disposed to face a heat radiation surface (rear surface in FIG. 6) 46b1 of the rear PTC heater 46b. The boiler block 60 is formed with a sterilization unit 51 that sterilizes water from the water supply tank 36 supplied through the water supply tube 43 using heat (residual heat) from the heat radiation surface 46b1 of the PTC heater 46b. . In this sterilization part 51, the water supplied through the water supply tube 43 is sterilized, for example, at 80 ° C. or higher for 30 seconds or longer.

  On the upper side of the boiler block 60, a gas-liquid separation unit 70 for temporarily storing the sterilized water is provided. In the gas-liquid separation chamber 71 in the gas-liquid separation unit 70, water supplied from the sterilization unit 51 and bubbles contained in the water are separated. Therefore, in the gas-liquid separation chamber 71, the water level is displaced downward as water containing more bubbles is supplied.

  The gas-liquid separator 70 is connected to a cylindrical water supply nozzle (protruding member) 72 that protrudes downward from the upper side of the gas-liquid separator 70. A portion below the midway in the vertical direction of the water supply nozzle 72 is located in the gas-liquid separation chamber 71.

  The upper end of the water supply nozzle 72 communicates with the inside of the foreign matter capturing part 80 disposed above via a mist joint 81. In the foreign matter catching part 80, a mist filter 83 for catching foreign matter contained in water flowing upward from the lower side (water supply nozzle 72 side) is provided. A mist tube 85 is connected to the upper end of the foreign matter catching portion 80 via a joint 84. A venturi-structured mist nozzle 17 is connected to the downstream end of the mist tube 85. As a result, the sterilized water that has passed through the mist filter 83 is supplied to the mist nozzle 17, and the mist nozzle 17 generates a cold mist that is maintained in a sanitary state suitable for beauty by a venturi effect. Such cold mist is discharged from the mist nozzle 17.

  As shown in FIGS. 6 and 7, the cold mist generating mechanism 45 is provided with a pair of pump blocks 52 so as to sandwich the water supply path from the boiler block 60 to the mist nozzle 17 from the left and right directions. . Each of these pump blocks 52 includes a pump 53 using a power source motor as a drive source, and a first air tube 54 that causes air sent from the pump 53 to flow toward the mist nozzle 17. The downstream end of each first air tube 54 is connected to a three-pronged air pipe 55. Such an air pipe 55 is connected to the mist nozzle 17 via the second air tube 56. That is, the air sent from each pump block 52 by the drive of each pump 53 is supplied to the mist nozzle 17 in a combined state.

  As a result, the air volume of air sent to the mist nozzle 17 is increased as compared with the case where there is one pump, and more cold mist is discharged from the mist nozzle 17. Therefore, in the present embodiment, the mist generating unit configured to mist the water sterilized in the sterilizing unit 51 by the mist nozzle 17, each pump block 52, the air pipe 55, and the second air tube 56 and discharge the mist to the outside. Is done.

Next, the boiler block 60 will be described. In the following description, the vertical direction corresponds to the vertical direction when the facial device 10 is installed on a horizontal plane.
As shown in FIGS. 6 and 8, a sterilization part 51 for sterilizing water and a communication path 61 located above the sterilization part 51 are formed in the boiler block 60. The communication path 61 is a path for guiding water sterilized by the sterilization unit 51 to the gas-liquid separation unit 70.

  Water is supplied from the water supply tank 36 to the sterilization unit 51 using the height between the water surface in the sterilization unit 51 and the water surface in the water supply tank 36, that is, the water head difference. The sterilizing unit 51 is disposed such that the upper end thereof is located below the lower end P1 of the storage space (liquid storage space) 36A for storing water in the water supply tank 36. In the present embodiment, the upper end of the sterilizing unit 51 is located at substantially the same position in the vertical direction as the lower end (that is, the bottom) P2 of the tank holder 35 positioned below the lower end P1 of the accommodation space 36A.

  As shown in FIG.8 and FIG.9, in the sterilization part 51, the inflow port 62 is formed in the lower end side, and the outflow port 63 is formed in the upper end side. Then, water from the water supply tube 43 flows into the sterilization unit 51 through the inflow port 62. Further, water in the sterilization unit 51 flows out from the outlet 63 to the communication path 61 and is supplied into the gas-liquid separation chamber 71 through the communication path 61.

  In such a sterilization part 51, a plurality (five in the present embodiment) of plates extending in a direction intersecting a virtual line S1 extending in a direction connecting the inlet 62 and the outlet 63 in a straight line (left and right in FIG. 9). The part (turbulent flow generation part) 64 is provided. These plate portions 64 are arranged at substantially equal intervals in the vertical direction. The plate portions 64 are a plate portion 64A, a plate portion 64B, a plate portion 64C, a plate portion 64D, and a plate portion 64E in order from the bottom. The plate portions 64 form a meandering path from the inlet 62 to the outlet 63 in the sterilizing portion 51.

  That is, the water that has flowed into the sterilization unit 51 through the inflow port 62 flows to the left in FIG. 9 through the first path 651 between the lower wall 51A of the sterilization unit 51 and the plate portion 64A. The water that has reached the downstream end (the left end in FIG. 9) of the first path 651 flows to the right in FIG. 9 through the second path 652 between the plate portion 64A and the plate portion 64B. The water that has reached the downstream end (the right end in FIG. 9) of the second path 652 flows through the third path 653 between the plate portion 64B and the plate portion 64C to the left in FIG. The water that has reached the downstream end (the left end in FIG. 9) of the third path 653 flows to the right in FIG. 9 through the fourth path 654 between the plate part 64C and the plate part 64D. Water that has reached the downstream end of the fourth path 654 (the right end in FIG. 9) flows to the left in FIG. 9 through the fifth path 655 between the plate portion 64C and the plate portion 64D. The water that has reached the downstream end (the left end in FIG. 9) of the fifth path 655 flows to the right in FIG. 9 through the sixth path 656 between the plate portion 64D and the upper wall 51B of the sterilization unit 51. Then, the water that has passed through the fifth path 655 flows out of the sterilization unit 51 through the outlet 63.

  At this time, a turbulent flow of water occurs in a portion 66 (a portion surrounded by a one-dot chain line in FIG. 9) where the flow direction of water is changed in the sterilization unit 51. As a result, water having a low temperature is mixed with water having a high temperature, so that the water temperature is made uniform in the sterilization unit 51.

Next, the effect | action of the sterilization part 51 of this embodiment is demonstrated.
Now, when the water of the sterilization part 51 is supplied to the gas-liquid separation part 70 side, water substantially equivalent to the supply amount is supplied from the water supply tank 36 through the water supply tube 43. And in the sterilization part 51, the water in the sterilization part 51 is sterilized by the residual heat of the PTC heater 46b.

  And the upper end of the sterilization part 51 is located below the lower end P1 of the accommodation space 36A in the water supply tank 36 (refer FIG. 8). Therefore, in the water supply path from the water supply tank 36 to the gas-liquid separation chamber 71, the water level fluctuates downstream from the sterilization unit 51 (that is, above the sterilization unit 51) due to the fluctuation of the water level in the water supply tank 36. To do. As a result, the amount of water stored in the sterilization unit 51 is substantially constant regardless of whether the amount of water stored in the water supply tank 36 is large or small. That is, regardless of the amount of water stored in the water supply tank 36, the amount of water supplied into the sterilization unit 51 is substantially constant. Therefore, if there is no change in the heating performance by the PTC heater 46b, the degree of variation in the sterilization action in the sterilization unit 51 is reduced.

Therefore, in this embodiment, the following effects can be obtained.
(1) The upper end of the sterilization unit 51 is located below the lower end P1 of the accommodation space 36A in the water supply tank 36. Therefore, if water is stored in the water supply tank 36, the amount of water stored in the sterilization unit 51 is constant. Regardless of the amount of water stored in the water supply tank 36, the amount of water supplied into the sterilization unit 51 is substantially constant. Therefore, compared with the case where the upper end of the sterilization part 51 is located below the lower end P1 of the accommodation space 36A, the variation in the sterilization effect of water in the sterilization part 51 can be reduced.

  (2) In the present embodiment, the upper end of the sterilizing unit 51 is located at substantially the same position as the lower end P2 of the tank holder 35 in the vertical direction. Therefore, even if there is no water stored in the water supply tank 36, the amount of water stored in the sterilization unit 51 is substantially constant as long as water is stored in the tank holder 35. Therefore, even when the facial device 10 is used with no water in the water supply tank 36, variation in the sterilization effect of water in the sterilization unit 51 can be reduced.

  (3) The sterilization unit 51 generates turbulent flow in the water. Therefore, the low-temperature water that has just flowed into the sterilization unit 51 and the high-temperature water that has already been heated in the sterilization unit 51 are mixed together. Therefore, the water temperature in the sterilization unit 51 can be made uniform, and the water sterilized in the sterilization unit 51 can be supplied to the gas-liquid separation unit 70 side. That is, cold mist kept in a hygienic state suitable for beauty can be discharged from the mist nozzle 17.

  (4) In the sterilization part 51 of this embodiment, by providing the some board part 64, water flows along the heat radiating surface 46b1 of the PTC heater 46b so that it may meander. That is, the water in the sterilization part 51 is heated uniformly by each part of the heat radiating surface 46b1 of the PTC heater 46b. Therefore, in the sterilization part 51, water can be sterilized suitably.

  (5) Moreover, the sterilization part 51 of this embodiment is sterilizing water using the residual heat from the PTC heater 46b which comprises the steam production | generation mechanism 44. FIG. Therefore, compared with the case where the heating apparatus only for sterilization is provided separately from the PTC heater 46b, it is possible to contribute to downsizing, cost reduction, and power saving of the facial beauty apparatus 10 as a whole.

  (6) Further, the heat released from the heat radiation surface 46b1 of the PTC heater 46b is absorbed by the water in the sterilization unit 51. That is, compared with the case where the sterilization part 51 is arrange | positioned in the position spaced apart from the thermal radiation surface 46b1, the thermal radiation efficiency from the thermal radiation surface 46b1 can be improved. As a result, the steam generation efficiency in the steam generation mechanism 44 can be improved.

In addition, you may change this embodiment into another embodiment as follows.
In the embodiment, in the communication passage 61 located between the sterilization unit 51 and the gas-liquid separation unit 70, as shown in FIG. The part 61A may be provided. In this case, in the communication passage 61, the passage cross-sectional area of the downstream portion of the throttle portion 61A (that is, the upper portion of the throttle portion 61A) can be reduced. Thereby, the inflow per unit time of the water from the water supply tank 36 side to the sterilization part 51 becomes small compared with the case where the throttle part 61A is not provided. As a result, the amount of decrease in the water temperature in the sterilization unit 51 due to the inflow of water from the water supply tank 36 side to the sterilization unit 51 can be reduced.

Note that a connecting pipe line may be provided between the communication passage 61 including the throttle portion 61A and the gas-liquid separation portion 70.

Further, the plate portion 64 may have any configuration other than the configuration extending in one direction (for example, a configuration having an arc shape).

  -In embodiment, if a turbulent flow generation part is the structure which can generate turbulent flow in water within the sterilization part 51, arbitrary structures may be sufficient as it.
