Abstract

This heating blower has a housing 1, a fan 2, a heater 3, and an electrostatic atomizing device 5. The electrostatic atomizing device 5 is provided in the housing 1 and discharges nanometer-size ion mist to the outside. The electrostatic atomizing device 5 comprises a discharging electrode 50, an opposed electrode 52 disposed opposite the discharging electrode 50, a cooling part 53 which cools the discharging electrode 50 to generate moisture from ambient air near the discharging electrode, and a high voltage applying part 55 which applies a high voltage between said discharging electrode and the opposed electrode to atomize water generated near the discharging electrode. Therefore, this heating blower can discharge nanometer-size ion mist to the outside without replenishment of water.

Claims

1. A heating blower with an electrostatic atomizing device comprising:

a housing with an air passage therein;

a fan disposed in said air passage to aspirate external air from an air inlet formed at an upstream portion of said air passage and discharge aspirated air to outside from an air outlet formed at a downstream portion of said air passage;

a heater disposed in said air passage to heat air to be discharged from said air outlet; and

an electrostatic atomizing device provided in said housing to discharge atomized water to outside,

wherein said electrostatic atomizing device comprises;

a discharging electrode,

an opposed electrode disposed opposite said discharging electrode,

a cooling part which cools said discharging electrode to generate moisture from ambient air near said discharging electrode, and

a high voltage applying part which applies a high voltage between said discharging electrode and said opposed electrode to atomize water generated near said discharging electrode.

2. The heating blower as set forth in claim 1, wherein

said fan is disposed at the upstream portion of said air passage and said heater is disposed at the downstream portion of said air passage,

said housing having a cooling passage branched from said air passage between said fan and said heater,

said discharging electrode being disposed in said cooling passage.

3. The heating blower as set forth in claim 1, wherein

said housing has a mist outlet for discharging the atomized water to outside,

said mist outlet being formed so that a discharging direction of the atomized water discharged from said mist outlet becomes parallel to a discharging direction of air discharged from said air outlet.

4. The heating blower as set forth in claim 1, wherein

said electrostatic atomizing device has a radiator for dissipating heat absorbed when said cooling part cools said discharging electrode,

said fan being disposed at the upstream portion of said air passage and said heater being disposed at the downstream portion of said air passage,

said radiator being disposed in said air passage between said fan and said heater.

5. The heating blower as set forth in claim 4, wherein

said radiator has a function of rectifying air flowing through said air passage.

6. The heating blower as set forth in claim 5, wherein

a cross section of said radiator which faces a pathway of the air flowing through said air passage has a uniform shape along the pathway of the air.

7. The heating blower as set forth in claim 1, wherein

said electrostatic atomizing device has a radiator for dissipating heat absorbed when said cooling part cools said discharging electrode,

said fan being disposed at the upstream portion of said air passage and said heater being disposed at the downstream portion of said air passage,

said housing having a heat radiation passage branched from said air passage between said fan and said heater,

said radiator being disposed in said heat radiation passage.
