装置。In an automobile heating system using engine cooling water as a heat source, an engine cooling water outlet 1a, a heater opening/closing valve 9, and a radiator 6
, water passage 178-17g passing through the engine cooling water inlet 1b
A heat storage water tank 8 is connected in parallel to the water passages 17b to 17C between the engine cooling water outlet 1a and the heater on-off valve 9.
Water passages 182 to 18C connected to the radiator 6 and water passages 19 bypassing the hot water inlet and outlet of the radiator 6 are provided, respectively, and water passages 173 to 17C between the engine cooling water outlet 1a and the heater opening/closing valve 9 are provided. A waterway opening/closing valve 10 that opens and closes, and a parallel switching valve 11 that switches the main water passages of the heat storage water tank outlet side passage 18b1, the heater on/off valve inlet side passage 18C1, and the bypass passage 19 are provided, and the water temperature in the heat storage water tank and engine cooling are adjusted. The waterway opening/closing valve 10 and the three-way switching valve 11 according to the comparison with the water temperature and the comparison between the water temperature in the thermal storage tank and the set value.
When the water temperature in the heat storage water tank is higher than the engine cooling water temperature and the water temperature in the heat storage water tank is equal to or higher than a set value, the heat storage water tank 8, the radiator 6, and the engine cooling water inlet 1b are connected in series by a control circuit 14 that opens, closes, and switches between the When the water temperature in the heat storage water tank is higher than the engine cooling water temperature (and the water temperature in the heat storage water tank is below a set value), the heat storage water tank 8 bypasses the radiator 6 and is directly connected to the engine cooling water inlet 1b. A hot water heating device for an automobile, characterized by forming a water passage.
