Description
Technical field
The utility model relates to technical field of solar, is specifically related to the upper and lower waterpipe temperature controller of a kind of solar water heater.
Background technology
Solar water heater product is with the feature of its green, energy-saving and environmental protection, safety, and the parent being more and more subject to consumers in general looks at., northern China extremely frigid zones due to winter colder, even minimum temperature reaches less than-20 DEG C.This just makes this area people use in winter solar water heater receive restriction.The blank in this field domestic has been filled up in the invention of solar water heater upper and lower waterpipe temperature controller.Although current solar water heater exempts from play antifreeze effect by force in northern area extremely frigid zones antifreezing measures 1, this measure of tube emptying, emptier is very complicated, brings very burden to user operation.2, self limiting heating cables is incubated because self limiting heating cables is a kind of power-controlled material, namely heating tape power is larger when the temperature is low, temperature is higher, along with the continuous rising of pipe temperature, heating tape power reduces gradually, temperature also decreases, until equalized temperature, reaches the object of pipe insulation.But heating tape power supply cuts off never, therefore bring many troubles to user.(1) take electricity, even summer has been forgotten power-off by certain customers, causes long-term energising, brings financial burden to user.(2) be energized for a long time, easily make heating tape tired, decrease the service life of heating tape.(3) because pipe insulation material is most of inflammable, the easy breaking out of fire of long-term energising.
Summary of the invention
The purpose of this utility model overcomes above shortcoming, provides that a kind of structure is simple, the upper and lower waterpipe temperature controller of solar water heater of power saving.
For achieving the above object, the technical scheme that the utility model is taked is:
The upper and lower waterpipe temperature controller of solar water heater, comprise contactor, indicator lamp, relay, temperature detector and heating tape composition, described heat detector accesses power supply after connecting with relay; Described contactor accesses power supply after connecting with heating tape, accesses power supply after described indicator lamp is in parallel with heating tape; Described relay is solid-state relay; Described heat detector is WDF20-L type heat detector, adjustable temperature scope be 0 ° ~ 5 ° namely 0 ° time close, open when 5 °.
When northern area extremely frigid zones temperature is lower than 0 DEG C, temperature-sensing element is connected, control relay adhesive, main circuit power is connected, heating tape is energized, and temperature raises, when temperature rises to 5 DEG C, temperature-sensing element disconnects, relay disconnects, the power-off of heating tape major loop, so repeatedly, pipeline is made to reach 0---5 DEG C of temperature, to reach the object of insulation.
The utility model utilizes temperature-sensing element, controls solid-state relay break-make, to realize heating tape interrupter duty, to reach safety, power saving, extends the object in heating tape life-span.
Accompanying drawing explanation
Fig. 1 is the utility model circuit theory diagrams.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the upper and lower waterpipe temperature controller of solar water heater, comprise contactor 1, indicator lamp 2, relay 3, temperature detector 4 and heating tape 5 and form, described heat detector 4 accesses power supply after connecting with relay 3; Described contactor 1 accesses power supply after connecting with heating tape 5, and after described indicator lamp 2 is in parallel with heating tape 5, the relay 3 accessed described in power supply is solid-state relay; Described heat detector 4 is WDF20-L type heat detector, adjustable temperature scope be 0 ° ~ 5 ° namely 0 ° time close, open when 5 °.
One, experimentation
1, temperature-sensing element is selected:
In order to select a kind ofly exactly at the temperature-sensing element that 0---5 DEG C of scope can control flexibly, to have finally chosen WDF20-L type temperature detector, this is a kind of adjustable device, is regulated by carefulness, it can be made to close 0 DEG C time, open when 5 DEG C.
2, controller makes:
After Fig. 1 circuit connection, by whole components and parts part, be contained in plastic casing, carry out sealing, waterproof, insulation, and power supply input, output and temperature-sensing element line are drawn.
3, temperature controller is put into refrigerator or refrigerator-freezer, regulate refrigerator temperature, meticulous inspection pilot bulb break-make situation.
Two, experimental result
Through experiment, record data, when refrigerator-freezer is adjusted to 0 DEG C, indicator lamp is bright, illustrates that power supply is connected, and when refrigerator-freezer temperature is adjusted to 5 DEG C, indicator lamp goes out, and power supply disconnects, and repetition test is all very successful.
