2)項に記載の自動車の排気熱利用式暖房装置。[Scope of Claim for Utility Model Registration] (1) A heater cock is opened in the cooling water circulation path where the cooling water after cooling the engine radiates heat in a radiator and then flows into the engine again. An exhaust heat exchanger installed in the engine exhaust pipe is provided with a heating circulation path for cooling water, which is further heated by an exhaust heat exchanger installed in the exhaust pipe, and then flows through the heater core of the heating unit and flows back into the engine. A bypass exhaust pipe that bypasses the exhaust heat exchanger is configured to branch, and a switching valve is provided at the branch, and the switching valve is operated so that when the heater stock is opened and the heater blower switch is turned on, the exhaust pipe provided with the exhaust heat exchanger is opened. a circuit that operates the switching valve to open the bypass exhaust pipe when the engine cooling water temperature exceeds a set value, and a warm-up detection switch that detects when the engine is warming up. A circuit that operates a switching valve to open the exhaust pipe equipped with a heat exchanger is provided, and the warm-up detection switch is connected to the EG
A heating device using exhaust heat for a vehicle, characterized in that the switch is used in common with a switch for controlling energization to an R solenoid and for controlling lighting of a lighting warning lamp. (2) The warm-up detection switch has one terminal that remains on while the engine is not warmed up and the other terminal that remains on after the engine has warmed up. The energizing circuit and the energizing circuit for the member that operates the switching valve to open the exhaust pipe provided with the exhaust heat exchanger are respectively connected to one terminal of the warm-up detection switch via a current backflow prevention element. , a heating system using exhaust heat for a vehicle according to claim (1) of the utility model registration, characterized in that the circuit for supplying electricity to the lighting lamp is connected to the other terminal of the warm-up detection switch. Device. (3) The circuit that operates the switching valve to open the exhaust pipe equipped with the exhaust heat exchanger when the heater stock is opened and the heater blower switch is turned on is equipped with a current backflow prevention element. Scope of claims for utility model registration, paragraph (1) or (
The automobile exhaust heat utilization type heating device described in item 2).
