| 摘要 |
The invention relates to a hair-dryer (10), having a housing (12) which has an air inlet opening (16) and an air outlet opening (18) for an air flow. Arranged in the housing (12) are a fan (21) and a heater (27), and a filter element (20) is assigned to the air inlet opening (16). Provided in the housing are recording means (32; 34) which generate an output signal, which is dependent at least on a temperature in the housing (12), and to which a signalling device (40) is assigned which can be actuated when a predeterminable threshold value level of the output signal has been reached. By means of the signalling device (40), the user of the hair-dryer (10) is shown that cleaning or exchange of the filter element (20) is required. <IMAGE> |
