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,

two conductive plates connected to the radiator to supply power to the radiator; 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,

wherein the plurality of insulation layers comprise a first insulation layer that surrounds the radiator and at least a portion of each conductive plate, and a second insulation layer that entirely surrounds the first insulation layer.

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
