An opening at the left end in the middle is configured as a steam spray port 9b.

  The water supply port 9a is connected in communication with the bottom of the water supply tank 16 via a water supply pipe 15 that forms a water supply passage therein. Therefore, liquid (water in this example) is always supplied from the water supply tank 16 to the steam generating unit 9. Is supplied. The upper half of the water supply tank 16 is exposed to the outside of the housing 3, and a plug 17 that opens and closes the water inlet of the water supply tank 16 is disposed in the exposed portion. Thereby, replenishment of the liquid to the water supply tank 16 is possible.

  The steam spray port 9b is opened toward the air blowing direction in the substantially radial center portion of the air passage, and is blocked by a moisture permeable waterproof film 11 that prevents the liquid from flowing and allows the humid air to pass therethrough.

  A steam heater 43 for heating the steam generating unit 9 is wound around the outer periphery of the steam generating unit 9. Thereby, when the liquid (water in this example) in the steam generating unit 9 is heated to become steam, the steam is ejected from the steam spraying port 9b.

The drive motor 5m of the fan 5 is connected to the DC output terminal of the bridge rectifier 41 in series.

  A contact S3 of the switch 47 is connected between the first voltage dividing resistor 43 and the second voltage dividing resistor 45, and a contact S4 of the switch 47 is connected between the diode 37 and the thermal fuse 39. The contacts S3 and S4 of these switches 47 are connected in series. The contact between the contact S3 and the contact S4 of the switch 47 and the connection between the second voltage dividing resistor 45 and the diode 37 are connected to each other.

  Here, the first voltage dividing resistor 43 of the driving motor 5m of the fan 5 is wound around the outer periphery of the steam generating unit 9 as shown in FIG. 1 and serves as a steam heater 43 for heating the steam generating unit 9. It is configured. The second voltage dividing resistor 45 is wound downstream of the steam generating unit 9 and upstream of the hot air heater 7 in the heater fixing unit 21, and does not heat the steam generating unit 9, It plays a role of assisting the warm air heater 7 by heating the air.

(Cold air blowing)
When the contact S1 of the switch 33 is turned on from the state where the contacts S1 and S2 of the switch 33 are OFF and the contacts S3 and S4 of the switch 47 are OFF, the drive motor 5m of the fan 5 is driven and the cool air is blown out from the outlet of the housing 3 It is blown out from 3c. At this time, the voltage dividing resistance of the drive motor 5m is the sum of the resistance values of the first voltage dividing resistor 43, the second voltage dividing resistor 45, and the diode 37. Since the resistance value is the highest, the blowing amount is the minimum value. It becomes.

  There are four stages of air flow including the first stage of the minimum value, and the next second stage is a state in which the contact S4 of the switch 47 is turned off and the contact S4 is turned on. The resistance is the sum of the resistance values of the first voltage dividing resistor 43 and the second voltage dividing resistor 45. The third stage is a state in which the contact S4 of the switch 47 remains OFF and the contact S3 is ON. The voltage dividing resistance of the drive motor 5m is the sum of the resistance values of the first voltage dividing resistor 43 and the diode 37. Become. The fourth stage, which is the maximum value of the blown air amount, is a state in which the contacts S3 and S4 of the switch 47 are turned on, and the voltage dividing resistance of the drive motor 5m becomes the resistance value of the first voltage dividing resistor 43.

(Hot air blowing)
When the contact S2 of the switch 33 that was OFF when the cold air is blown is turned on (that is, when both the contacts S1 and S2 of the switch 33 are turned on), the warm air heater 7 generates heat. Therefore, the air flowing through the housing 3 is warmed and blown out from the outlet 3c of the housing 3 as hot air. At this time, the first voltage dividing resistor 43 of the drive motor 5m is wound around the steam generating section 9 as shown in FIG. 1 to heat the steam generating section 9, so that the steam generating section 9 has a sufficient temperature. When it reaches, the liquid inside boils and steam is blown out from the steam spraying port 9b of the steam generating section 9. It should be noted that the air volume adjustment is the same as when the cold air is blown out even when the hot air is blown out.

The water retaining member 13 is different from the first embodiment in that the water retaining member 13 faces the outside through the steam spray port 9b.

  According to such 2nd Embodiment, in addition to the effect of 1st Embodiment, since the water retention member 13 is filled in the steam generation part 9, the volume density of the liquid in the steam generation part 9 is small. Therefore, the liquid is easily vaporized, the steam generation efficiency of the steam generating unit 9 can be improved, and the steam generation time can be shortened.

  In addition, since the water retaining member 13 is filled in the steam generating unit 9, liquid leakage can be prevented without blocking the steam spray port 9b with a moisture permeable waterproof film, and the steam generating unit 9 can be configured with a simple configuration. Can be configured.

  Furthermore, in this embodiment, since the water retaining member 13 is exposed to the outside of the steam generating unit 9 through the steam spray port 9b, the vaporization speed is particularly fast.

Eruption stops. Further, since the amount of liquid in the steam generating unit 9 can be adjusted by frequently opening and closing the slide valve 51, the amount of generated steam can also be adjusted.

  The communication portion 16b and the second tank 16c of the water supply tank 16 can be regarded as a water supply passage that allows the water supply tank 16 and the steam generating portion 9 to communicate with each other.
