Abstract
The utility model discloses a high temperature resistant and incrustation resistant sun shield for a solar energy water heater. An automatic foldaway sun shield is installed above a solar energy vacuum tube. A controller is excited by a temperature sensor to fold and unfold the sun shield. The sun shield can prevent from generating incrustations resulting from over-high water temperature. The sun shield product is a square flat slab structure, belongs to an auxiliary product of solar energy field, and solves the problem that the solar energy water heater generates incrustations in summer resulting from over-high water temperature.
Description
Affiliated technical field
The present invention relates to vacuum tube and the inner incrusted problem of water tank that solar water heater causes because of water temperature is too high when summer.
Technical background
Use solar water heater commonplace in the Modern Family; and in use all there is a common shortcoming in various brand solar water heaters on the market: under the reasonable situation of sun in summer; or the user goes on business several days without hot water; the temperature of water is very high in the water heater, the situation (water temperature reaches 100 ℃) that occurs boiling through regular meeting.Common people think that this has been a phenomenon, illustrate that the water heater quality is good, and the water quick heating has but all been ignored following problem: 1. at temperature height in summer, family reduces the use amount of hot water, have more than is needed at all so many hot water.2. in the too high life-span that can reduce solar water heater of temperature, quicken the aging of parts (particularly rubber seal).3. the too high danger of being scalded that in use increased of water temperature.4. when water temperature surpassed more than 70 ℃, incrustation scale began to form, and incrustation scale has influenced the thermal conversion efficiency of solar energy, has increased the maintenance cost of solar energy.
For too high each producer of water temperature in summer without limits, feel that all water temperature is high more good more, this is wrong viewpoint in fact.And for each producer of incrustation scale problem good solution of neither one all, the anti-incrustation scale of the magnetization of minority producer propaganda, or the anti-incrustation scale of magnesium rod is just had a talk about in theory, but do not prevent the formation of incrustation scale in actual use, what have adds fixed filter when last water, but can only filter big foreign material, can not filter out the calcium ions and magnesium ions in the water, therefore various brands solar energy all is to be called to the solar energy scale removal by maintenance mans after the user uses 2--3 now, has increased cost and labor strength greatly.
Summary of the invention
In order to overcome the shortcoming of the existing too high generation incrustation scale of solar water heater water temperature in summer, the utility model is installed one above solar energy vacuum tube can self-jacked sunshading board, can control water temperature automatically below 70 ℃.
The technical scheme that its technical problem that solves the utility model adopts is: installing one above solar energy vacuum tube can self-jacked sunshade curtain, it is made up of electronic curtain draw off gear and control system, the similar electronic rear-projection curtain principle of curtain draw off gear, form by curtain, curtain box, curtain framework, fixed mount, either-rotation motor etc., drive the folding and unfolding of curtain by either-rotation motor, during the forward power connection, motor is just changeing opens curtain, solar energy vacuum tube integral body is covered, block sunlight, water temperature no longer raises.During the negative sense power connection, curtain is packed up in the motor counter-rotating, and solar energy works on.Control system is made up of temperature sensor (can use on the solar energy), automatic control switch, hand switch and line, when temperature reaches design temperature, sensor sends signal to automatic control switch, connect the forward power supply of motor, curtain is opened, solar energy vacuum tube is covered, and water temperature no longer raises; When user's a part of hot water of using up, behind water heater filling cold water, water temperature drops to design temperature when following, and controller is received the negative sense power supply of signal connection motor, and curtain is packed up, and solar energy works on.If the user goes on business or temporarily do not use hot water, can curtain be opened also that (annotate: after this device as the formal production, its control circuit can be integrated in the solar energy control panel, and switch is contained on the control panel by hand switch, with solar energy be one, make to install and use all to make things convenient for).
The beneficial effects of the utility model are that on the basis that is not influencing the normal use of solar water heater, the water temperature of control solar energy can be not too high, slows down solar energy part parts and wear out, and prevents to produce incrustation scale, reduces maintenance cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is product appearance figure of the present utility model (curtain is opened a half)
Fig. 2 is outside drawing when sunshading board is contained in that curtain is not opened on the solar energy
Fig. 3 is outside drawing when sunshading board is contained in that curtain is opened on the solar energy
1. temperature sensors among the figure, 2. temperature sensor line, 3. curtain support, 4. fixed mount, 5. curtain box, 6. either-rotation motor, 7. curtain.
The specific embodiment
Among Fig. 1, curtain box (5), curtain (7), either-rotation motor (6) are installed on the curtain support (3).
Among Fig. 2, the curtain device is installed in the solar energy vacuum tube top by fixed mount (4), and water temperature is not when reaching design temperature, and curtain is not opened, the solar energy operate as normal.
Among Fig. 3, water temperature is when reaching design temperature, temperature sensor (1) sends signal by temperature sensor line (2) to gauge tap, connect motor forward power supply, the motor-driven curtain is opened, and solar energy vacuum tube is covered, and sunshine can not shine vacuum tube, water temperature no longer continues to raise, and solar energy quits work.
When the user travels on official business or several days during without hot water, can open curtain by hand switch, solar energy is quit work when the user needs more hot water, also can the manual-lock curtain, make solar energy be in duty always.
Claims (3)
1, the anti-incrustation scale sunshading board of the anti-high temperature of a kind of solar water heater, it excites control panel to control the folding and unfolding of sunshading board by cooling-water temperature sensor, controls solar water-temperature automatically and moves in not incrusted temperature.
2, the anti-incrustation scale sunshading board of the anti-high temperature of solar water heater according to claim 1, it is characterized in that: a retractable sunshade curtain is installed above solar energy vacuum tube, it is made up of electronic curtain draw off gear and control system, automatically excite control system to send by cooling-water temperature sensor to motor, folding and unfolding by either-rotation motor drive curtain also can be exchanged into manual mode.
3, the anti-incrustation scale sunshading board of the anti-high temperature of solar water heater according to claim 1, it is shaped as the flat design of square, is fixed on the solar energy vacuum tube top by fixed mount.
