Vacuum pipe for solar water heater

Abstract

The invention discloses a vacuum pipe for a solar water heater. The vacuum pipe for the solar water heater comprises an outer glass pipe and a vertical rod, wherein an inner glass pipe is arranged atthe inner side of the outer glass pipe, and a cavity is formed in the inner side of the inner glass pipe; an electrical heating rod is installed in the cavity; water inlet ports are located in the topends of the inner glass pipe and the outer glass pipe, and a water storage chamber is formed between the inner glass pipe and the outer glass pipe; a first cleaning block is arranged in the water storage chamber, and a first magnetic block and first cleaning cotton are fixed to the first cleaning block; a fixed plate is installed on the outer glass pipe, and a slide groove is formed in the surface of the fixed plate; the end of the vertical rod is located in the slide groove; and a second cleaning block is installed on the vertical rod, and a second magnetic block and second cleaning cotton are fixed to the second cleaning block. According to the vacuum pipe for the solar water heater, regular cleaning for the inner wall of the vacuum pipe is facilitated, so that the accumulation of waterscale in the vacuum pipe is effectively prevented; and meanwhile, convenient dust cleaning can be carried out on the outer wall of the vacuum pipe, so that more reasonable design is achieved.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a vacuum tube for solar water heaters. Background technique [0002] With the development of science and technology and the improvement of people's living standards, solar water heaters have become widely used equipment in people's lives. Glass vacuum tubes are the core components of solar water heaters and play a key heating role. There is a shortcoming that long-term use is easy to accumulate and deposit scale in the vacuum tube during use, which is inconvenient to clean, and the dust deposited on the surface of the vacuum tube cannot be removed conveniently. In view of the above problems, it is urgent to carry out innovative design on the basis of the original vacuum tube. Contents of the invention [0003] The purpose of the present invention is to provide a vacuum tube for solar water heaters to solve the problems in the above-mentioned background art that sca...
