とを特徴とする太陽熱温水器の凍結防止装置。In a solar water heater that is provided with a heat collecting part that heats cold water using solar heat, a hot water tank that stores hot water heated by the heat collecting part, and a water supply source that is connected to the hot water tank, the hot water tank The water supply port connected to the water supply source is opened, and an overflow tank is provided to keep the water level of the hot water tank constant. A water surface detecting section of a water surface sensing means is provided to sense and cut off the water supply from the water supply source, and the overflow tank and the hot water supply pipe for supplying hot water are connected to a delay means, a check means, or an inverted U-shaped siphon pipe. The hot water storage tank is connected to the hot water supply pipe by a branching means, and the water level sensing means connects the hot water storage tank to a circulation pipe that connects the heat collecting section and the hot water storage tank. Disposed above the water level in the overflow tank to be sensed, a drain port is formed at the bottom of the heat collecting section, and a low temperature opening/closing means is connected to this drain port to prevent the outside air from being below a certain temperature. , the low-temperature opening/closing means opens and the hot water in the heat collecting section and the circulation pipe is drained to the outside from the drain port, and at this time, the water surface sensing means does not operate and water is not supplied from the water supply port.
