に運転することができる。Since the heat storage material 21 in the heat exchanger 2 and the crystal nucleation material 41 in the seed crystal container 4 come into contact with each other, crystallization of the heat storage material progresses all at once, the supercooled state collapses, and a large amount of solidification occurs. The latent heat is released and the temperature of the heat storage material 21 increases. At this time,
After a predetermined time has elapsed, the delay timer 15 energizes the small motor 62 to drive the washer pump 63. The washer fluid 60 passing through the large-diameter portion 67 of the washer fluid hose 66 absorbs the latent heat held by the heat storage material 21, and the washer fluid 60 is heated. Heated washer fluid 60 (discharge pressure car 1 kg f/ct
A, discharge flow rate -10cc/sec) is the washer
The liquid is sprayed from the liquid spray nozzles 64, 65, and the ice that has formed on the front windshield of the vehicle A can be efficiently and instantaneously thawed. Therefore, when the outside air temperature is low and ice has formed on the front window B of the vehicle, such as early in the morning in winter, the washer fluid 60 is instantly heated by the latent heat held by the heat storage material 21. A desired field of view can be secured in a short time, and the driver can drive the vehicle A safely.
凝固の潜熱を放出して結晶状態となった蓄熱物質２１に
再び熱エネルギーを蓄えさせるためには、上述した操作
を繰り返せば良い。また潜熱の放出も同様に反復して行
なうことができる。In order to cause the heat storage material 21 that has become crystalline by releasing the latent heat of solidification to store thermal energy again, the above-described operations may be repeated. The release of latent heat can also be repeated in the same way.
冬期以外はメインスイッチ１４を開成しておくことによ
り、消費電力を減少できる。Power consumption can be reduced by leaving the main switch 14 open except during winter.

The valve is closed and the supply of engine cooling water to the heat exchanger 2 is stopped, so that loss of heat from the heat storage material 21 can be prevented. The delay timer 18 is replaced by a thermistor, and the solenoid valve 73 can be controlled to open or close depending on the temperature inside the heat exchanger 2.
