Abstract

The present invention relates to a steam head of a cleaner. The present invention includes a steam head including: a body defining an exterior, and a steam generating device provided on the body to generate steam through heating water supplied through a heater, the heater including a radiator of a ceramic material, and a plurality of insulation layers for insulating the radiator, wherein the plurality of insulation layers is formed of one of or a combination of one or more of magnesium oxide (MgO), a slurry-phase insulator, and an insulation film. Thus, through the present invention, a heater'"'"'s heat radiating performance is improved to facilitate generation of steam.

Claims

1. A steam head comprising:

a body defining an exterior; and

a steam generating device provided on the body to generate steam through heating water supplied through a heater, the heater comprising a radiator of a ceramic material, and

a plurality of insulation layers for insulating the radiator, wherein the plurality of insulation layers is formed of one of or a combination of one or more of magnesium oxide (MgO), a slurry-phase insulator, and an insulation film.

2. The steam head according to claim 1, wherein the radiator is a positive temperature coefficient (PTC) ceramic.

3. The steam head according to claim 1, wherein the steam generating device comprises:

a reservoir in which water is stored;

a heating portion into which water from the reservoir flows; and

at least one or more of a heater provided to the heating portion to heat water that flows in.

4. The steam head according to claim 1, wherein the insulation layers comprise:

a first insulation layer formed through an insulation film enclosing the radiator;

a second insulation layer formed through an insulation film enclosing the first insulation layer; and

a third insulation layer formed through an insulation film enclosing the second insulation layer.

5. The steam head according to claim 4, further comprising a case provided outside the third insulation layer, according to moisture contact of the third insulation layer.

6. The steam head according to claim 5, further comprising formations on a surface of the case to increase a static surface area.

7. The steam head according to claim 1, wherein the insulation layers comprise:

a first insulation layer formed of a slurry-phase insulator in a shape enclosing the radiator; and

a second insulation layer using an insulation film and enclosing the first insulation layer.

8. The steam head according to claim 1, wherein the insulation layers comprise:

a first insulation layer formed of a slurry-phase insulator in a shape enclosing the radiator; and

a second insulation layer formed of a magnesium oxide (MgO) and enclosing the first insulation layer.

9. The steam head according to claim 1, wherein the insulation layers comprise:

a first insulation layer formed of a magnesium oxide (MgO) and enclosing the radiator; and

a second insulation layer formed using an insulation film and enclosing the first insulation layer.

10. The steam head according to claim 1, wherein the insulation layers comprise:
