Abstract

PURPOSE:To always secure the superior viewfield by taking out the hot-air from the outer periphery of the exhaust pipe of an engine and blowing out the hot air onto a front window and speedily melting the snow which lies on the front window. CONSTITUTION:An outer pipe 3 having a fin 7 for improving the absorption of the exhaust heat is installed on one part of the outer periphery of the exhaust pipe 2 of an engine 1, and the air introduced from an air inlet opened in the lower part of the outer pipe 3 can be heated. The heated air is taken out into a hot air pipe from a hot air taking-out port formed in the upper part of the outer pipe 3, and pressure-increased by a fan 5 and blown out towards a front window from a hot-air taking-out port 6. Therefore, the snow which lies on the front window can be speedily molten, and the superior viewfield can be secured.

（Ｂ）従来の技術これまでは、積雪時に対するフロントウィンドの対策は
ありません。(B) Conventional technology Until now, there has been no countermeasure for front windshields in case of snowfall.

（Ｃ）発明が解決しようとする問題点フロントウィンドに積雪及び、凍結した雪を熱風で融か
し、短時間でワイパーの稼働が出きることによる視界の
確保。(C) Problems to be solved by the invention Snow accumulated on the front windshield and frozen snow are melted with hot air, and wipers can be activated in a short time to ensure visibility.

（Ｄ）問題点を解決するための手段エンジンの排気管の外周に、熱効率を良くするためのフ

方を熱風の取り出し口にし、これをファンにてフロント
ウィンドに導き、積雪及び、凍結した雪を融かす。(D) Measures to solve the problem: An outer pipe with fins is installed around the outer circumference of the engine exhaust pipe to improve thermal efficiency, with the lower part serving as an air inlet and the upper part serving as an outlet for hot air. is guided to the front windshield using a fan to melt snow and frozen snow.

使用については、熱風を送るファンと電磁弁を連動させ
、ファンの回転と同時に電磁弁が熱風管のシャッターを
開き、ファンの停止で電磁弁が、熱風管のシャッターを
閉じる。In use, a fan that sends hot air is linked to a solenoid valve, and when the fan rotates, the solenoid valve opens the hot air pipe shutter, and when the fan stops, the solenoid valve closes the hot air pipe shutter.

フロントウィンド面へは、複数の吹き出し口を、扇状に
配置し効率をたかめる。Multiple air outlets are arranged in a fan shape on the front windshield to increase efficiency.

（Ｅ）発明の効果本発明の効果は、フロントウィンドに積雪した雪を融か
