Abstract
Provided is a heater assembly for a hand-held appliance. The assembly includes a ceramic heater substrate having a heated region that includes heater elements for converting electrical energy to heat, and an unheated region adjacent to the heated region. The assembly includes a heat sink for dissipating heat from the heater elements, where the heat sink extends from the heated region of the ceramic heater substrate. The assembly includes electronic control devices for controlling electrical energy supply to the heater elements, and which are mounted at the unheated region of the ceramic heater device. The assembly includes heat dissipation means to dissipate heat from the heater elements to maintain the unheated region at a lower temperature than the heated region.
Claims20
A heater assembly, comprising:
- a ceramic heater substrate having a first region that includes one or more heater elements for converting electrical energy to heat, and a second region adjacent to the first region;
- a heat sink for dissipating heat from the heater elements, the heat sink extending from the first region of the ceramic heater substrate,
- one or more electronic control devices for controlling electrical energy supply to the one or more heater elements, the one or more electronic control devices being mounted at the second region of the ceramic heater device;
- and,
- heat dissipation means arranged to dissipate heat from the heater elements to maintain the second region at a lower temperature than the first region.
