であつた。[Prior Art] In a vehicle hot water heater that uses engine cooling water, a heater core consisting of a plurality of hot water heat exchangers is provided in the vehicle interior as necessary. Conventionally, in this case, the cooling water flow path through which the cooling water supplied from the engine's water jacket flows is separated into multiple cooling water flow paths, and a control valve is provided in the cooling water flow path leading to each heater core to adjust the flow rate of the cooling water. The heating capacity of each heater core was controlled by operating each adjustment valve. For example, if a heater core that uses engine cooling water is installed in the front and rear seats of a car, the cooling water supplied from the engine's water jacket is guided through cooling water piping, and the cooling water piping is routed halfway through. A branch path is provided to separate the cooling water between the front seat heater core and the rear seat heater core, and a front seat control valve is provided between the branch path and the front seat heater core to adjust the flow rate of the cooling water. A control valve for the rear seat is also provided between the road and the heater core of the rear seat, and an operation panel for the front seat that operates the control valve of the heater core of the front seat is installed on the instrument panel in the vehicle interior, and a control valve for the rear seat is also installed between the heater core of the rear seat. An operation panel for the rear seats was provided to operate the control valves. For this reason, one cooling water piping branch, two control valves that adjust the flow rate of the cooling water, and two operation panels that operate the two control valves, each located at a position that can be operated by the crew, are required. The above configuration has a large number of parts and high production costs, and the large number of connections between each of the parts and the cooling water piping is likely to cause water leakage, and the installation work is also difficult.

However, this control has the drawbacks of being complicated, expensive, and impractical.
