Abstract | A haircare appliance 100 comprises drive circuitry 110, 112, a controller 114 in communication with the drive circuitry for controlling a drive current output by the drive circuitry, and a temperature sensor 118 for supplying a temperature signal to the controller. The temperature signal is indicative of a temperature of an electronic circuit within the haircare appliance. The controller is configured to estimate an ambient temperature at least partly based on the temperature signal, and to prevent the drive circuitry from outputting the drive current when the estimated ambient temperature is lower than an ambient temperature threshold. The electronic circuit may comprise a processor, and the temperature sensor may be integrated into the processor. The drive circuitry may comprise a motor driver 110 and/or a heater driver 112. The controller may be configured to estimate the ambient temperature at least partly based on the drive current or a power related to the drive current. The temperature sensor may be housed in a second housing (134, fig. 3), separate from the heating element housing. The invention helps prevent condensation forming which can damage the components. |
