Abstract

The utility model relates to an improved solar water heater. The water up-flow pipe orifice and the water down-flow pipe orifice of a water tank are connected on a controller, the controller shell is provided with a valve rod guide pipe and an evacuation vent pipe which are paratactic; the water up-flow and down-flow pipe orifices, water supply and discharge pipe orifices, the pipe orifice of guide pipe and the pipe orifice of the vent pipe are respectively connected on a four-way pipe piece that is arranged at the bottom of the controller; the lower end valve head of the valve rod fits the pipe orifice, the top part of the vent pipe is provided with a sealed valve head, the pull rods of the valve rod and the sealed valve head are respectively connected with the two ends of a permanent magnet, electromagnets with the opposite current directions are arranged above and below the permanent magnet respectively, and a circuit control connecting wire that is used to connect the electromagnets is connected inside a switch box through a connection box. The utility model has reliable performance, easy use and control, which can supply the hot water directly by opening the valve, as well as the instant on and easy use, especially when in use in winter, the utility model can avoid the frost-crack of the water pipes fundamentally caused by no water in the water up-flow and down-flow pipes, thus the solar water heater can be used normally in winter with the good performance.

Description

Improved solar water heater

Technical field

The utility model relates to a kind of improved solar water heater.

Background technology

Solar water heater is with energy-conservation, outstanding advantage such as environmental protection has obtained popularization and application widely, in normal use, all the time be full of water in its upper and lower conduit, at need during with the hot water in the solar water heater, open valve after, what at first emit is water in the upper and lower conduit, be cold water, be only emitting of hot water then, use inconvenience, and season in the winter time, water in the upper and lower conduit is frozen easily, water pipe appears by the bursting by freezing phenomenon, even water tank is through the insulation processing, also because be subjected to the problem of upper and lower conduit bursting by freezing, and cause winter in cold, solar water heater can not normally be used, and serviceability is poor, and is very unfortunate.It is 200520081151.0 antifreeze, instant-heating solar water heater that the applicant had once designed a kind of patent No., easy to use, can obtain hot water at any time fast, has avoided upper and lower conduit by the problem of bursting by freezing.But, to find in the application still to have unsatisfactory place, valve rod has inconvenience in water tank inside more, influences performance.

Summary of the invention

The purpose of this utility model is to provide a kind of improved solar water heater, and dependable performance uses control convenient, can obtain hot water at any time fast, and avoid upper and lower conduit by the problem of bursting by freezing.

Improved solar water heater described in the utility model, comprise water tank, water pipe and valve, water tank is provided with exhaust outlet, the backwater mouth of pipe and upper and lower conduit mouth, its water tank upper and lower conduit mouth is connected on the controller, be provided with stem guiding pipe arranged side by side and emptying breather pipe in the housing of controller, the upper and lower conduit mouth, the water supply and sewage mouth of pipe, the guide pipe mouth of pipe and the breather pipe mouth of pipe are connected on the four-way pipe fitting of controller bottom, the lower end valve head and the mouth of pipe of valve rod adapt, the top of breather pipe is fitted with the sealing valve head, the pull bar of valve rod and sealing valve head is connected to the two ends of permanent magnet, the upper and lower of permanent magnet is respectively equipped with the electromagnet of current opposite in direction, and the circuit control wiring that connects electromagnet is connected in the switch enclosure by terminal box.

In controller housing, be lined with insulation material,, avoid being frozen as polyurethane heat insulation material etc.

Above controller, preferably establish sky shade, strengthen protective action, prevent to expose to the sun and rain, prolong the service life of each parts.

In the utility model, can do some adjustment or increase some corresponding components, can improve serviceability better, as increasing a plurality of controlled valves, increase diversion pipeline etc. according to actual instructions for use and conventional general knowledge and experience.

Controller of the present utility model is independent of outside the water tank, guaranteed the reliability of solar water heater integrated performance, automatically control by high-speed double electromagnet, easy to use, and be provided with the emptying facility, no cold water stores in the pipeline, when needing hot water, open valve and get final product direct hot-water supply, instant-heating, easy to use, when particularly using in the winter time,, fundamentally avoided the water pipe from freezing crack problem owing to do not have water in the upper and lower conduit, make the solar water heater use that can do as usual in the winter time, serviceability is good.

Description of drawings
