To provide a vehicle anti-fogging device enhancing heating efficiency in a vehicle under low temperature environment, and efficiently suppressing fogging on a window glass while suppressing electricity consumption.SOLUTION: An anti-fogging device is provided with a desiccant type dehumidifier, a glass heating device and a control device. The dehumidifier performs a dehumidifying operation adsorbing moisture in a vehicle cabin to a moisture adsorbing part, and a regeneration operation making the moisture adsorbed by heating the dehumidifying part. The glass heating device heats a window glass via a heating wire. The control device controls the operations of the dehumidifier and the glass heating device. When suppressing fogging of the window glass under the situation where the temperature in the vehicle cabin is equal to or lower than a prescribed temperature, the control device operates both the glass heating device and the dehumidifier during a temperature in the vehicle cabin reaches a threshold value temperature, stops the glass heating device at a time when the temperature in the vehicle cabin, and exceeds the threshold value temperature or reduces output of the glass heating device.SELECTED DRAWING: Figure 2

    【課題】低温環境下における車室内の暖房効率を高め、かつ、電力消費を抑制した状態で窓ガラスの曇りを効率良く抑制することができる車両の防曇装置を提供する。【解決手段】防曇装置は、デシカント式の除湿装置と、ガラス加熱装置と、制御装置と、を備える。除湿装置は、車室内の水蒸気を吸湿部に吸着させる除湿運転と、吸湿部を加熱して吸着した水蒸気を脱離させる再生運転を行う。ガラス加熱装置は、電熱線で窓ガラスを加熱する。制御装置は、除湿装置とガラス加熱装置の作動を制御する。制御装置は、車室内の温度が所定温度以下の状況で窓ガラスの曇りを抑制する場合に、車室内の温度が閾値温度に達するまでの間、ガラス加熱装置と除湿装置をともに作動させ、車室内の温度が閾値温度を超えた時点でガラス加熱装置を停止させ、若しくは、ガラス加熱装置の出力を低下させる。【選択図】図2
