PURPOSE: A high temperature steam spraying device for cleaning a vehicle is provided to improve the reliability of products by increasing heat resistance, crack resistance, and durability and to prevent water leakage with a firm connection structure. CONSTITUTION: A high temperature steam spraying device for cleaning a vehicle comprises a head gun(10), a hose(50), and a connector(20). The head gun sprays high temperature steam. The hose transfers the steam to the head gun. The connector connects the head gun and the hose. A first Teflon layer(51), a reinforcement layer(55), and the first Teflon layer are successively laminated on the hose inner surface. The reinforcement layer is composed of a stainless steel braid(52) and a thread braid coated on the outer surface of the stainless steel braid. A nipple coupling part(57) on which the first Teflon layer and the reinforcement layer are laminated is formed on the front end of the hose. |
