Glass——Metal Vacuum Top Water Solar Collector Ball Water Heater

Abstract

The invention relates to a glass-metal vacuum water upward push-out solar heat collection ball water heater. The water heater is provided with a double-layer spherical shell, wherein the outer layer is made of glass, the inner layer is made of metal, and the space between the inner layer and the outer layer is vacuumized; a protective cap of an exhaust nozzle is arranged at the upper portion of the double-layer spherical shell; a displacement ball is arranged in the double-layer spherical shell; an outer conical neck is arranged at the lower portion of the double-layer spherical shell and inserted in a conical cylinder; the opening of the neck is sealed through a spiral sealing plug, and each end face of the sealing plug is provided with three through holes; the two through holes in the upper end face of the sealing plug are connected with a water supply pipe and a water drain pipe, and the other through hole in the upper end face is a water scale discharge hole; three inserting and sealing pipes are arranged at the orifice edges of the through holes in the lower end face, and four guide posts are arranged on the periphery of the through holes and inserted into inserting and sealing pipe connectors and guide holes of a connecting disk. The glass-metal vacuum water upward push-out solar heat collection ball water heater can accurately track diurnal motion and annual apparent motion of the sun without a moving part, and maintenance is not needed; during annual apparent motion, the northern hemisphere of a heat collection ball can acquire solar energy provided during half-year daytime; hot water acquired during one day can be completely discharged for use; the water heater can be mounted on the roof or the wall of a building or the ground; the water heater can be connected with a fast heating electric water heater or a gas water heater in series for use; the water scale can be stored in a neck tube and can be discharged regularly.

Description

technical field [0001] The invention relates to a solar heat utilization device, in particular to a glass-metal vacuum-topped solar heat-collecting bulb water heater. Background technique [0002] A Chinese patent discloses an invention patent of "Glass Vacuum Solar Collector Ball Water Heater" (Patent No. ZL200410026080·4). figure 1 Namely the structure of its heat collecting ball. [0003] The heat-collecting ball has a spherical double-layer casing formed by sealing the outer glass bulb 1 and the inner glass bulb 2, and a glass spherical shell-shaped displacement device 4 is arranged inside the double-layer casing. The lower end of the outer glass bulb 1 has an open tapered neck, and the lower end of the inner glass bulb 2 has an open straight neck. The two necks are sealed into one neck by using crystalline solder glass. There is a closed conical tube at the top of the inner glass bulb 2, and a conical tube with a through hole at the top of the outer glass bulb 1, the ...
