Abstract

The utility model relates to a solar radiation vacuum heat-preservation water heater, which is mainly composed of a shell, an intra-cavity and a full-water auto-control system; wherein, when the sunlight radiates the intra-cavity through the shell of a water tank to heat the water in the intra-cavity and then forms second-time heating and preserve the water in the intra-cavity because the space between the shell and the intra-cavity is pumped to form vacuum and freeze-resistance speed-heating liquid is arranged in the vacuum layer. Compared with the prior art, no glass vacuum pipe is needed to heat the water in the intra-cavity and preserve the heat with foamed polyamine-ester. Due to the above characteristics, the water tank can be made into any geometric shapes. The water flowed out from an overflow pipe is used by the control system to generate induction signal and control the operation mechanism. A check valve is arranged for a cooling-water magnetic valve without checking function, and a emptying valve and a locking joint are arranged for a hot-water magnetic valve to achieve the purposes of auto-stopping after the water is filled up and auto-emptying. When the hot water is in use, an auto-locking function is added to the cooling-water magnetic valve and the emptying valve to prevent the mistaken operation of the two valves from affecting the normal using water-temperature.
