Embodiment 1
[0011] Such as figure 1 As shown, the scale-proof solar water heater of the present embodiment includes a vacuum tube 1 and an insulated water tank 2. An airtight container 3 is placed in the insulated water tank 2, and the top of the airtight container 3 extends out of the top surface of the insulated water tank 2. A piston 4, the piston rod 5 of the piston 4 stretches out from the top surface of the airtight container 3, and is connected with a shielding sheet 6 through a transmission mechanism, and the shielding sheet 6 can completely or partially cover the vacuum tube when the piston rod 5 rises.
[0012] The above-mentioned transmission mechanism includes a bracket 7 installed on the top surface of the insulating water tank 2, a connecting rod 9 installed on the bracket 7 through a pin shaft 8, and the shielding sheet 6 and the piston rod 5 are respectively connected to the two ends of the connecting rod 9. When the piston rod 5 When lifting, the connecting rod 9 can be r...

The invention aims to provide an incrustation-scale-proof solar water heater, and can guarantee the using effect of the solar water heater. The incrustation-scale-proof solar water heater comprises a vacuum tube and a heat preservation water box, wherein a sealed container is arranged in the heat preservation water box, and the top end of the sealed container stretches out the top surface of the heat preservation water box; a piston is arranged in the sealed container, and a piston rod of the piston stretches out the top surface of the sealed container so as to be connected with a shielding piece through a transmission mechanism; and the shielding piece can shield the whole or part of the vacuum tube when the piston rod is lifted. When the water temperature in the heat preservation water box rises, the air temperature in the sealed container rises and the sealed container expands, the expanding gas is upward lifted by the means that the piston pushes the piston rod, so that the whole or part of the shielding piece shields the vacuum tube, and the irradiation of sunshine to the vacuum tube is reduced, and the inner water temperature is prevented from being overhigh; and the incrustation scale only can be generated when the temperature is above 70 DEG C, therefore, the generation of incrustation scale can be prevented only if the water temperature is enabled to be below 70 DEG C by virtue of the action of the shielding piece.
Description
technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a scale-proof solar water heater. Background technique [0002] The earth's solar energy is rich in resources, which can be used for free, without transportation, and without any pollution to the environment. Therefore, it is a popular energy source and represents the trend of future energy sources. Now solar water heaters have become more and more popular, but after existing solar water heaters have been used for a period of time, there will be scale problems inside. If scale cannot be prevented or cleaned in time, the use effect of solar water heaters will be seriously affected. Contents of the invention [0003] The purpose of the present invention is to propose a scale-proof solar water heater to ensure the use effect of the solar water heater. [0004] The anti-scaling solar water heater of the present invention comprises a vacuum tube...
