Water tank of solar water heater

Abstract

The invention discloses a water tank of a solar water heater. The water tank comprises a shell, an inner container and a heat insulating material, wherein the inner container is arranged in the shell; the heat insulating material is filled between the inner container and the shell; the water tank is characterized in that a jacket for covering an orifice of a vacuum tube is also arranged in the inner container; and the top of the jacket is provided with an opening, and the bottom of the jacket is hermetically connected with the inner wall of the inner container. According to the water tank, water in the jacket and the vacuum tube is separated from water outside the jacket in the water tank through the jacket which is additionally arranged in the inner container for covering the orifice of the vacuum tube, so that scales produced by deposition and heating of the water outside the jacket is prevented from polluting the vacuum tube, thereby effectively preventing scaling, prolonging the service life of the vacuum tube and meanwhile preventing the vacuum tube from cracking due to quenching. A fine tube which is arranged on the top of the jacket is lower than the water line; and when water leaks in the jacket, serious water leakage of the water tank can be prevented to save the water resource.

Description

technical field [0001] The invention belongs to the field of solar water heaters, in particular to a solar water heater water tank. Background technique [0002] In existing solar water heaters, the structure of the water tank is usually mainly composed of an outer shell, an inner tank installed in the outer shell, an insulating material filled between the inner tank and the outer shell to form a box body, and an overflow pipe arranged on the box body, Composed of water inlet pipe and water outlet pipe. However, existing water tanks often have the problems of serious scaling, water leakage, and vacuum tube bursting due to large temperature changes when adding water. [0003] In order to overcome the above problems, workers in the art have also made relevant adjustments and improvements to the structure of the water tank. For example, the Chinese utility model patent No. CN201220074049.8 discloses a "solar water heater water tank". The water inlet and outlet pipes are arran...
