Claims

[Scope of utility model registration request]

A hot water piping route that supplies water to the heat exchanger of the combustor to heat and heat the water into the bathtub of the bathroom, and a reheating system that circulates the hot water in the bathtub through the heat exchanger of the combustor. In the automatic water heater, the water level detection mechanism is installed in the hot water supply piping route to open and close the hot water supply piping route. An inner cylinder to which hot water is supplied with the hot water supply piping route facing the provided upper water receiving part, and an overflow port provided around the inner cylinder and at its upper end side, and hot water is supplied from the lower end opening of the inner cylinder. It consists of a water receiving hopper that forms a double cylinder shape with an outer cylinder that supplies water into the bathtub, and the lower end opening of the inner cylinder of this water receiving hopper extends downward from the water level detection position in the bathtub. It has a structure in which a branch pipe is branched from the outer cylinder at a position corresponding to the lower end opening of the inner cylinder, and a pressure detector is provided in this branch pipe, and the heat exchanger of the combustor is installed in this water level detection mechanism. A hot water supply device characterized by circulating hot water in a reheating piping route passing through.
