Abstract
PURPOSE: To unnecessitate the draining of water in a water heater and to prevent freezing of water with low electricity cost, by arranging an ultrasonic vibrator in the water heater so that the freezing of water in a water passage is prevented by the ultrasonic vibration.
CONSTITUTION: In a main value stop type water heater, a water flowing from an inlet 1 into the heater is stopped at a stop-cock 2. When the stop-cock 2 is opened, the water flows through a water pressure regulator 3, a water pressure responsive diaphragm chamber 4, a water temperature regulator 6, and a heat exchanger 6 to an outlet 7. On the other hand, a gas flowing in at a gas inlet 8, flows via a gas cock 10 and a water pressure responsive gas valve 11 that is opened by the action of the water pressure responsive diaphragm chamber 4, reaches burner 12 where it is burned to transmit the heat to the heat exchanger 6 and flows out from an outlet 7. In this arrangement, the ultrasonic vibrator 13 is provided whose vibrating member 14 transmits its vibrations to a part of the water passage to vibrate water molecules to prevent the water from freezing.
