Abstract
The invention provides a full-automatic pipeline emptying solar water heater, and relates to a high-efficiency freeze-proofing solar water heater with a simple structure, wherein a control part is not arranged in a water tank, cold and hot water pipes can be emptied automatically in the whole course. When a user requires showering, the use of hot water can be completed as long as a start button on a computer control display is pressed; when the water tank is full of water, water feeding can be automatically closed by virtue of the computer control display; and after the user finishes showering and leaves, a computer control display can automatically drain the water which is in the water outlet and feed pipes of the water tank into a water holding barrel for daily water use of the user, and the emptied water delivery pipes can resist server cold weather, and cannot be frozen or blocked, and power insulation is not required in winter. The full-automatic pipeline emptying solar water heater is an energy-saving solar water heater with simple structure, freeze proofing, power saving, safe use and small daily maintenance workload.
Description
Technical field the present invention relates to a kind of solar energy that utilizes with the solar water heater of cool water heating, particularly the high efficient antifreeze solar water heater of the automatic complete emptying mode of a kind of water-supply-pipe.
The existing solar water heater of background technology all is that the heat that utilizes vacuum tube or heat pipe to absorb the sun is transmitted to the attemperater energy storage again, and the output of hot water depends on the quantity of thermal-collecting tube, and the hot water amount of actual output is determined by the capacity of attemperater.Main Problems is: aqueduct very easily frozen block bursting by freezing in the situation of not doing the ribbon heater protection; Existing solar water heater, after the water in the attemperater is drained, a small amount of water of storing in the vacuum tube, logical being exposed to the sun and drying in a few days then caused the anhydrous air drying of vacuum tube, makes the vacuum tube state that reaches a high temperature, at this moment, if user's water filling in the attemperater, current can flow down along fervid tube wall, shine into vacuum tube tube wall be heated inequality and explosion; Solar water heater need add the protection of ribbon heater and insulating sponge because of its aqueduct, has namely wasted electric power energy since like this, and it is attractive in appearance to have affected again building.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, and aqueduct does not need the auxiliary insulation of electricity, booster not, uncongealable energy-saving and high efficient automatic solar water heater.
Realize that the technical scheme that purpose of the present invention is taked is: comprise the overflow-type attemperater, aqueduct, the water level temp probe, computer control display instrument, upper water solenoid valve door, the emptying solenoid valve door, mixing valve, it is characterized in that: running water pipe is connected respectively to mixing valve behind the door through upper water solenoid valve, emptying solenoid valve door and water tank upper hose, radiator drain is connected with mixing valve with the emptying solenoid valve door respectively, computer control display instrument respectively with the water level temp probe, upper water solenoid valve is connected with the emptying solenoid valve door, described computer control display instrument is by start button, start-up circuit, the human body sensing holding circuit, the water level temp probe, the emptying solenoid valve controller, upper water solenoid valve controller, display screen and control circuit form, described emptying solenoid valve door is the open type three-way magnetic valve, and valve is open mode when uncontrolled; Described upper water solenoid valve door is normal-closed electromagnetic valve, and valve is closed condition when uncontrolled; Described mixing valve is the shower mixer valve door.When the water level temp probe monitored warning line, computer control display instrument can be controlled separately the water solenoid valve door is closed.The overflow-type attemperater is the 201020523799X patent that adopts, and upper hose enters inside at water tank bottom, upper hose after arriving tank top under be bent to water tank bottom, and the place apart from water pipe highest point 1-5cm below the water pipe crooked position arranges an emptying air admission hole, the numerical value of 1-5cm generally can be considered according to water tank capacity and local temperature Change, this numerical value should be slightly larger than the height of hot water static expanding in the water tank, guarantees can not flow into behind the hot water expansion in the water-supply-pipe after emptying.The setting of this emptying air admission hole also is for fear of when water-supply-pipe is emptying water tank being found time.
The present invention is simple in structure, and is simple to operate, and antifreeze not consuming electric power uses safety, and the user need not worry about frozen pipe, booster, overflow and other regular maintenance, has greatly improved the effect of solar water heater, is the typical energy-conservation efficient solar water heater of saving worry.
Description of drawings
Fig. 1 is system construction drawing of the present invention
Fig. 2 is the principle framework figure of computer control display instrument
Among the figure: 1-overflow-type attemperater, 2-water level temp probe, 3-water tank upper hose, 4-radiator drain, 5-emptying solenoid valve door, 6-mixing valve, the upper water solenoid valve door of 7-, 8-running water pipe, 9-air admission hole.
The specific embodiment: as shown in Figure 1: running water pipe 8 is connected respectively to mixing valve 6, emptying solenoid valve door 5 and water tank upper hose 3 through behind the upper water solenoid valve door 7, radiator drain 4 is connected with mixing valve with emptying solenoid valve door 5 respectively and is connected, computer control display instrument is connected with the emptying solenoid valve door with water level temp probe 2, upper water solenoid valve door 7 respectively and is connected, mixing valve 6 is also connecting shower nozzle, and a steel ladle is set under the delivery port of emptying solenoid valve door 5.
When needing bathing, the user presses the start button on the computer control display instrument, computer control display instrument starts and begins to show, the interior human inductor of computer control display instrument this moment detects the human body existence and makes and starts continuity, computer control display instrument output control signal, the emptying solenoid valve door is controlled and closes; Upper water solenoid valve door is controlled and opens, and running water enters respectively in attemperater and the mixing valve, and hot water enters the mixing valve from the radiator drain overflow in the attemperater, and regulate mixing valve and can obtain suitable hot water this moment.
When user's bathing is complete leave after, human inductor detects human body and does not exist and control circuit is quit work, upper water solenoid valve door is out of hand and close running water; The emptying solenoid valve door is out of hand and open, the interior water of this moment radiator drain and water tank upper hose all is discharged in the steel ladle by the emptying solenoid valve door, behind the tube emptying, liquid level remains on the position of air admission hole 9 in the water tank, this position is lower than water-supply-pipe mouth of pipe place, so also can not flow in the water-supply-pipe behind the hot water expansion.Water-supply-pipe after emptying namely can be resisted severe cold weather., the water-supply-pipe after emptying namely can be resisted severe cold weather.
