| 摘要 |
<p>The invention concerns an appliance (1) for heating a fluid, comprising a reservoir (5) temporarily coupled to a base (2), said reservoir (5) being designed to contain said fluid to be heated; means (10) for heating said reservoir (5); means for controlling (17) said heating means (10) including a temperature sensor (20) capable of generating an information representing the temperature of the fluid to be heated, said temperature sensor comprising: means for transmitting (21) an electromagnetic wave beam; means for reflecting (22) said beam; means for receiving (23) said reflected beam, the transmitting (21) and the receiving (22) means being located on the base (2) of the appliance, and the reflecting means (22) being located on the reservoir (5), opposite said transmitting (21) and receiving (22) means. The invention is characterised in that the reflecting means change shape when the reservoir temperature varies.</p> |
