<p>PURPOSE: A solar water heating apparatus is provided to supply hot water using a hemisphere solar heat collecting plate, to enhance heat efficiency by rotating the heat collecting plate with a solar heat position sensor and to heat water at dawn by a supersonic heater using midnight electricity. CONSTITUTION: A solar water heating apparatus contains a hemisphere heat collecting plate(2) heating a water circulating pipe(1) using a concave mirror or metal having high reflectivity. The heated water is stored in a hot water storage tank(11) through water circulating pipes(4,7). A water circulating motor(8) continuously supplies water to the pipe(1). The hemisphere heat collecting plate is sealed by a glass(3) to collect solar heat even in winter. A heat sensor(5) senses the position of the sun and drives a directional rotation motor(6). A rotating plate(9) is moved along the movement of the sun with the hemisphere heat collecting plate by the directional rotation motor. A supersonic heater keeps the temperature of hot water using frictional heat and vibration from the vibrator of a supersonic wave. Then, hot water is supplied from a heating and supplying pipe(13).</p> |
