Full-automatic solar water boiler

Abstract

A full-automatic solar water boiler is mainly composed of a heat collector, a heat collector water inlet pipe, a heat collector water outlet pipe, an electromagnetic valve, a flow limiting pipe, a flow guiding pipe, a pre-heating pipe, pipe opening plugs, a communicating pipe, a heat preserving bottle plug, a heat preserving bottle, a temperature probe, an electric heating pipe, a temperature controller, a time control switch and a light-operated switch, wherein a tap water pipe is connected with the water inflow end of the electromagnetic valve; the water outflow end of the electromagnetic valve is connected with the flow limiting pipe in which a flow limiting nozzle is plugged in; the other end of the flow limiting pipe is connected with the heat collector water inlet pipe; the other end of the heat collector water inlet pipe is connected with one pipe opening plug; one end of the heat collector water outlet pipe is connected with another pipe opening plug; the pipe opening plugs where the heat collector water inlet pipe and the heat collector water outlet pipe are located and the other pipe opening plugs between the heat collector water inlet pipe and the heat collector water outlet pipe are connected in series through the communicating pipe; and after being filled and coated with structural adhesives, the pipe opening plugs connected in series are plugged into the heat collecting pipe openings correspondingly; and the time control switch, the light-operated switch and the electric heating pipe are connected in series. The full-automatic solar water boiler has the beneficial effects that boiled water reaching the drinking standard can be produced; the boiled water producing process is automatic; and the bursting problem of a heat collecting pipe is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a fully automatic solar water boiler. Background technique [0002] The technology of making water heaters from general-purpose all-glass vacuum heat-collecting tubes is relatively mature, but multiple technical problems need to be solved to make water boilers from all-glass vacuum heat-collecting tubes. First of all, it is necessary to solve the large temperature difference between tap water and boiling water, which may easily cause the heat collecting tube to burst; secondly, it is necessary to solve the problem that the boiled water produced must be boiled water, but not boiled water for a long time and repeatedly; The problem of scale deposition; to achieve fully automatic provision of boiling water, it is necessary to solve the problem of using solar energy to heat when the sun appears. When the sun should come out but not appear, the electric he...

Problems solved by technology

First of all, it is necessary to solve the large temperature difference between tap water and boiling water, which may easily cause the heat collecting tube to burst; secondly, it is necessary to solve the problem that the boiled water produced must be boiled water, but not boiled water for a long time and repeatedly; The problem of scale deposition; in order to achieve fully automatic provision of boiling water, it is necessary to solve the problem of using solar energy to heat when the sun appears, and when the sun should come out but not appear, automatically enable electric heating, and automatically distribute the produced boiled water into thermos bottles technical issues within

The patented technology of patent authorization announcement number CN103277909B provides a "solar collection device for drinking water supply", but there is a problem that the water in the heat collecting tube is boiled repeatedly for a long time and the upper part of the heat collecting tube loses water, which causes the local temperature in the tube to be too high and cause the heat collecting tube to burst.
