程度であった。As can be seen from this, in the comparative example, the surface temperature of the mirror is lower.
It takes about 10 minutes to reach 25 ° C. However, in the case of this embodiment, the central part of the heating element is continuously energized in advance, the surface of the mirror is warmed to a certain temperature, and the outer part is heated by one changeover switch. Because of the heat generation, the rise time was about 1/2, that is, about 5 minutes.
また、消費電力は常時通電した場合について比較する

施例のものは連続通電用の一回路のみであるため1/7の5
Wである。Also, comparing the power consumption in the case where the power is always supplied, the conventional power supply is 35 W because it is composed of one circuit, and the power consumption in this embodiment is only 1/7 because it is only one circuit for continuous power supply.
W.
このように、本考案による防曇鏡は、発熱体の中央部
だけで曇りを防止できるうちは中央部にのみ通電させ、
曇りがひどくなった場合は外側部にも通電し、両発熱部
