Abstract
The utility model belongs to an automatic draining freezing-proof solar water heater of a solar water heater. An upper and a lower water pipelines are inserted into the side wall of a hot water tank with a heat preservation layer. An air inlet valve of a special pipeline is arranged at a vertically bending bottom which is abutted to a tank body in an inner chamber of the water tank. Air can enter the upper and the lower water pipelines after a bath is completed. Accumulated water can be automatically discharged. Thus, the utility model has the advantages of freezing prevention in winter, pipeline blocking prevention, normal utilization of the solar water heater in winter, convenient installation, time saving and material saving.
Description
The utility model belongs to apparatus for heating water by solar energy, particularly a kind of automatic emptying freezing-proof type solar water heater.
Traditional solar water heater all is to insert upper and lower water from water tank bottom or bottom, water tank two ends, takes the method for falling into water to use.To be that the intubate silica gel sealing ring is easily aging leak its shortcoming, and upper and lower waterpipe jointing adopts riveted joint or welding, easily twists bad solar water heater tank inner container during installation, and cold season, upper and lower waterpipe easy freezing or block caused water heater not use.
The purpose of this utility model provides a kind of automatic emptying freezing-proof type solar water heater, takes direct insertion upper and lower water pipe, and automatic exhaust-valve is installed, upper and lower waterpipe can not freeze winter, and hot and cold water is unimpeded, the vacuum heat-collecting tubular type, simple installation is saved mounting material.
The purpose of this utility model is achieved like this: a kind of automatic emptying freezing-proof type solar water heater, form by boiler, upper and lower waterpipe.Described boiler is for being filled with heat-insulation layer 5 between inner water tank 1 and water tank foreskin 2, described upper and lower waterpipe 7 passes water tank foreskin 2 from the upper right side, heat-insulation layer 5 vertically bends towards inner water tank 1 bottom, also be connected to pipe special exhaust-valve 6 in water tank foreskin 2 exits, two ends at the lower end of upper and lower waterpipe 7 three-way pipe 11, one termination running water control valve, 10, one termination hot water control valves 8 and shower 9; Being inserted with air inlet and exhaust piper 4 at the top of boiler, inserting overflow pipe 3 at sidewall, is water-temperature water-level alarm socket 12 in overflow pipe 3 terminations.
Described pipe special exhaust-valve 6 leaves air admission hole 6.1 for to be pasted with rubber tip 6.2 in the lower end of electromagnet 6.3 in the bottom, rubber tip 6.2 gets lodged on the air inlet 7.1.
The heat-insulation layer 5 of described boiler is A, B expanded material.
A mechanical vent valve can also be installed by described pipe special exhaust-valve place, its handle rotating mechanism is connected to indoor, manually control.
The utility model is compared with prior art: the automatic emptying freezing-proof type of the utility model solar water heater is the vacuum tube heat collecting type, owing on upper and lower waterpipe, be connected to the pipe special exhaust-valve, make the automatic emptying of this pipeline, no water in the upper and lower waterpipe, it is low because of the yard piping environment temperature to have solved four seasons type solar water heater, the out of use problem of the freezing pipeline of ice up in winter, and outdoor upper and lower conduit road does not need insulation, save the water heater mounting material, also reduced installation procedure.
Below in conjunction with description of drawings, the utility model is further specified.
Fig. 1 is automatic emptying freezing-proof type solar water heater structure schematic diagram.
Fig. 2 is Figure 1A portion structural representation.
By automatic emptying freezing-proof type solar water heater structure schematic diagram shown in Figure 1.Its boiler by inner water tank 1 outer wrap one deck heat-insulation layer 5 after, wrap by water tank foreskin 2 again, on the boiler left surface, insert overflow pipe 3, insert inlet and outlet intubate 4 at the top, insert upper and lower waterpipe 7 on the boiler right side, in inner water tank 1, vertically bend towards the bottom, pipe special exhaust-valve 6 is housed in the boiler outside.When using the water heater bathing, as long as Open valve 8, because the effect of siphonage and potential energy, hot water in inner bag 1 will automatically gush out from shower 9, when bathing complete, when not needing hot water, can press the push button of pipe special exhaust-valve, electromagnet 6.3 inhales rubber 6.2 from air inlet 7.1, and air side enters automatically, sewer pipe 7, to go up, waters in the sewer pipe 7 are pressed into inner water tank 1 and from valve 8, shower 9 is discharged, and keeps no waters in the upper and lower conduit road 7, even in winter of cold, on, sewer pipe 7 is not afraid of freezing yet, block, vacuum tube thermal-arrest solar water heater can be used in the same old way.
In addition, the pipe special exhaust-valve can also be controlled with mechanical valve, just turning handle is caused by a long draw indoor, by Artificial Control.
