FIG. 1 is a diagram showing an embodiment of the present invention. First, to explain the configuration, a water jacket 1 for cooling an engine has a water jacket 1 for circulating hot water heated by cooling the engine. Circulation route 2
A heater core 3 is interposed in this circulation path 2. The heater core 3 is made up of a tube and fins, and the hot water passing through the inside of the tube heats the air 4 passing through the surfaces of the tube and fins, and the heated warm air heats the interior of the vehicle. A combustion type heater 5 is interposed on the upstream side of the heater core 3 in the circulation path 2, and this heater 5 is designed to further heat the hot water that has been heated to some extent by the engine by the combustion heat of the fuel. A three-way valve 6 is interposed between the heater core 3 and the heater 5 in the circulation path 2, and this three-way valve 6
A first flow path 6a that connects to the heater core 3 via a hot water pot 7 that adjusts the hot water flow rate, and a second flow path 6 that connects to the heater core 3 by bypassing the hot water pot 7.
b, and a third flow path 6c that bypasses the hot water pot 7 and the heater core 3 and connects to the return path of the circulation path 2. An output terminal of a controller 8 is connected to the switching operation section 6d of the three-way valve 6, and a combustor 5a of the heater 5 is connected to another output terminal of the controller 8. Three temperature sensors T 1 , T 2 , and T 3 are connected to the input terminal of the controller 8, respectively. The first sensor T 1 measures the temperature on the return path of the circulation path 2, and the second sensor T 2 measures the temperature on the return path of the circulation path 2. The third sensor T3 detects the temperature on the upstream side of the heater 5 of No. 2, and the temperature of the oil that lubricates the engine.
It is now possible to input .
次に作用を説明する。 Next, the action will be explained.

When the third sensor T3 detects a temperature lower than the set value, the controller 8 outputs a switching signal to the operating part 6d of the three-way valve 6, causes the three-way valve 6 to open the third flow path 6c, and at the same time , the controller 8 activates the heater 5 to supplementally heat the hot water. As a result, the entire amount of hot water heated by the heater 5 bypasses the water tank 7 and the heater core 3 and returns to the water jacket 1, rapidly warming the engine. Therefore, the engine quickly warms up and reaches the required power operating condition.

い。 Next, when the car is idling, the third
When the sensor T 3 detects a temperature higher than the set value and the first sensor T 1 detects a temperature higher than the set value, the controller 8 outputs a switching signal to the operation part 6 d of the three-way valve 6 to turn the three-way valve 6 on. The second flow path 6b is opened, and at the same time, the controller 8 causes the combustor 5a of the heater 5 to continue operating to supplementally heat the hot water. As a result, hot water that has not been heated to a temperature sufficient for heating by the engine is auxiliary heated by the heater 5 to reach an appropriate temperature, and the entire amount flows to the heater core 3 bypassing the water tap tank 7. In the heater core 3, the air is heated with this hot water to maintain the required heating. Furthermore, a third sensor T 3 , a second sensor T 1 , a second sensor
When both sensors T 2 detect temperatures above the set value,
The controller 8 outputs a command signal to the operating section 6d of the three-way valve 6, and the three-way valve 6 opens the first flow path 6a. Therefore, the hot water passes through the hot water tank 7, passes through the heater core 3, returns to the water jacket 1, and circulates, and the air is heated in the heater core 3 to perform predetermined heating. Temperature adjustment of heating air is done with Hot Water Kotoku 7.
This is done by adjusting the hot water flow rate. At this time, the combustor 5a of the heater 5 is stopped by the controller 8, and auxiliary heating of the hot water is not performed.

定めてある。 The relationship between each of the sensors T 1 to T 3 and the passage through which hot water flows and the ON/OFF status of the heater is as follows. However, the set temperature is determined according to the relationship T 3 < T 1 < T 2 .

Although the case where the heater is used has been described, the heater is not limited to this, and may be, for example, an electric heater or the like. Further, the set temperature value of each temperature sensor can be appropriately selected.
