Abstract
The invention discloses a plunger type emptying defroster for a suction pipe of a solar water heater. The defroster comprises a solar insulating water tank, the suction pipe and a return pipe. The defroster is characterized in that the upper end of the suction pipe extends into the solar insulating water tank, water inlet and outlet and gas inlet and outlet are arranged on a plunger type controller and controlled by a micro low speed motor, and meanwhile, upper hot water is just used by control of a floating ball. According to the plunger type emptying defroster for the suction pipe of the solar water heater, as an emptying device in the suction pipe is arranged in the water tank, the defroster is emptied completely, so that the defrosting effect is improved. In anti-freezing seasons or under normal application, the micro low speed motor is not started, so that the electric consumption is saved. As the floating ball is used to position during water release, water released every time is the hottest water in the water tank, so that the defroster can be widely applied to solar water heaters.
