Claims

[Scope of Claim for Utility Model Registration] 1. A gas supply path for hot water supply and reheating is branched from a common gas introduction path, and a solenoid valve for hot water supply, etc. is provided in the gas supply path for hot water supply to face the air supply path. ,
and hot water temperature control means for hot water supply comprising a burner attached to a heat exchanger for hot water supply, and a solenoid valve for reheating provided in the gas supply path for reheating and facing the air supply path, and for reheating. A bathtub with hot water supply having hot water temperature control means with a burner attached to the heat exchanger, and a fan provided at one end of the air supply path to generate an air volume for promoting combustion to each of the burners. In the hot water temperature adjustment device, a proportional control valve for hot water supply and a proportional control valve for reheating are provided in the hot water supply gas supply path and the reheating gas supply path, respectively, and a hot water temperature measurement value and a hot water temperature setting value. Outputs control signals to each of the proportional control valves above based on input signals such as
A water temperature control device for a bathtub with hot water supply, further comprising: a proportional control valve drive section that outputs a drive signal to the fan according to the combustion amount of each of the burners. 2 The proportional control valve for hot water supply and reheating controlled by the proportional control valve drive unit consists of one proportional control valve provided at a branch point of the gas introduction path, and a solenoid valve in the gas introduction path for hot water supply. 2. The water temperature control device for a bathtub with hot water supply according to claim 1, wherein a control signal is outputted from the proportional control valve driving section so that the proportional control valve is fully opened when the proportional control valve is in the closed state.
