Abstract

The utility model discloses an automatic-discharge solar water heater which comprises a water tank case, a polyurethane foamed insulating layer, a stainless steel water tank inner core, a gas intake/exhaust hole, a detecting probe, an electric heater, a hot water outlet, a control instrument and a hot water supply valve. The automatic-exhaust solar water heater is characterized in that: a polystyrene foamed heat-insulating layer is arranged between the polyurethane foamed heat-insulating layer of the water tank and the stainless steel water tank inner core, a polyethylene air isolating layer is arranged between the two heat-insulating layers. The high-level segment of a water delivery pipe communicates with the hot water outlet via an outlet water low-pressure solenoid valve, the middle-level segment of the water delivery pipe communicates with a shower spray via the hot water supply valve, and the low-level segment of the water delivery pipe communicates with a tap water pipe via a water-injection low-pressure solenoid valve. When the water heater is turned off, the water pipe is automatically emptied. Additionally, the water heater has the advantages of no use of the electrically-heating tape for heat insulation on the pipe wall, instant heat upon turning-on, long-lasting heat-insulating effect and low power and water consumption.

Description

A kind of solar water heater of automatic emptying

Affiliated technical field

The utility model relates to a kind of solar water heater of automatic emptying, belongs to machinery manufacturing technology field.

Background technology

Solar energy, as a kind of cleaning, environmental protection, the cost free energy, utilized by human extensive exploitation, solar water heater is wherein a kind of, still, can't emptying after the water pipe of existing solar water heater is closed, water temperature descends rapidly in the pipe, especially in the winter of northern low-temperature cold, can cause water pipe to freeze even spalling is scrapped, for addressing this problem, to when being installed, water heater the water pipe winding be wrapped up, in order to antifreeze with the ribbon heater, insulation, heat up, also have the people on product, to design the magnetic valve emptying, but, because low temperature also can influence the magnetic valve serviceability, damage easily and lost efficacy, need the electric power support equally, therefore, this product also is not really the solar product on the pure meaning at present, simultaneously, and the individual layer insulation, heat is lost fast, and water heater is lowered the temperature rapidly.

Summary of the invention

The utility model provides a kind of solar water heater of automatic emptying at the problems referred to above, and it can make water heater after closing, water pipe just is drained in passing, need not twine the ribbon heater insulation on the tube wall, instant-heating, make insulation more lasting, thereby reach economize on electricity, water saving, purpose of energy saving.

Task of the present utility model is finished as follows: it is by tank shell, polyamine fat insulating foam layer, the stainless steel water tank inner bag, the air intake-exhaust hole, detection probe, electric heater (making to replenish the energy when not having sunlight), hot water outlet, control instrument and hot water use valve to constitute, adopt on the structure: between water tank polyamine fat insulating foam layer and stainless steel water tank inner bag, set up one deck foamed polystyrene heat-insulation layer, and between two heat-insulation layers, set up the polyethylene air barrier, high position in water-supply-pipe is communicated with hot water outlet by the water outlet low-voltage solenoid valve, meta uses valve to be communicated with shower head by hot water, and low level is communicated with running water pipe by the water filling low-voltage solenoid valve.

During the utility model work operation, when detection probe detection water tank was anhydrous, control instrument was opened the water filling low-voltage solenoid valve and is injected cold water by water-supply-pipe to water tank, and air is discharged by the air intake-exhaust hole in the water tank, reaches predetermined water level water filling low-voltage solenoid valve and closes; Open the use switch of control instrument when using hot water, water outlet low voltage electromagnetic opening of valves, hot water is delivered to the hot water use side by water-supply-pipe, opens hot water and uses valve can use hot water; The use switch of closing control instrument, the water outlet low-voltage solenoid valve is closed, the water-supply-pipe emptying; In water tank, replenish air by the air intake-exhaust hole when water tank and water-supply-pipe draining, go round and begin again, can realize the energy-saving and water-saving purpose of energy saving.
