The utility model has the advantages of low cost, good linearity degree, good reliability, good interchangeability, simple art and rapid reflecting speed.
Description
The utility model relates to a kind of solar water heater water-temperature water-level display control device.
Solar water heater spread to huge numbers of families in recent years as a kind of environment-friendly type energy-saving product of safe and cleaning, and generally reflection is good, rising from now on, no matter be that city or rural demand amount are very big.Water-temperature water-level display control device matched with it, manufacturer is also quite a lot, but will accomplish reliablely, easy to maintenance, and technology is simple, and cheap person does not so far as I know also have now.And whether they control it with water tank middle water level height and intake, no matter water tank temperature how, till your the given setting value of intaking always.I think can not intake when water temperature is low in the water tank or few water inlet, and the cloudy day can not intake, and fine day can be intake more, can make full use of solar energy like this.
The purpose of this utility model provides a kind of reliable, and is easy to maintenance, and technology is simple, cheap solar water heater water-temperature water-level display control device.
In order to achieve the above object, the utility model is taked following measures:
The solar water heater water-temperature water-level display control device be electric potential signal with cooling-water temperature sensor output behind amplification and rectification circuit, by water temperature display displays temperature, simultaneous temperature setting apparatus output signal is succeeded electrical equipment through on-off circuit; The electric potential signal of level sensor output by the water level indicator light indicated water level, is reported to the police by water level alarm behind comparison circuit, by relay control magnetic valve or booster pump, regulates water level range by the water level settings device simultaneously.Water-temperature water-level sensor has voltage-stabilized power supply, its anodal series connection is connected to first, second current-limiting resistance, first current-limiting resistance is connected and is connected to first to the n proportion resistor, first links to each other with height level sensor contact in the water tank respectively to the n proportion resistor, second current-limiting resistance links to each other the voltage-stabilized power supply minus earth with temperature sensing element in the water tank.
The utility model has the advantages that:
1) price is low, and element is easily bought: only need several 1% the metalfilmresistor and the PN junction of silicon diode or triode as water-temperature water-level sensor, the electronic component expense amounts to 0.2 yuan and just can accomplish;
2) linearity is good: is linear relationship at 0～100 ℃ with interior its variation as make temperature sensor of the silicon PN junction, does not need temperature curve to proofread and correct and just can use, and error can be in 1 ℃, so circuit is simple;
3) good reliability, long service life: the temperature coefficient of this PN junction changes because of the time is long hardly, can be described as semi-permanently, destroys so long as not the artificial origin, can use for a long time.Being placed on the open air also is difficult for being worn by thunderbolt, because of the direct ground connection of his negative pole, improved his reliability, if any use thermistor, its annual gradient is big, have with integrated temperature sensors such as AD590 or LM35, price height not only, because of being placed on the open air, being easy to make moist influences precision, is struck by lightning to wear and can not use;
4) interchangeability is good: what this machine was used is resistive element and amplifier, and its linear relationship is fine, and every instrument can cooperate arbitrarily with sensor and not influence use, and this gives and produces and maintenance brings a lot of convenience;
5) technology is simple: water-temperature water-level sensor can directly be put into water does not need specially treated just available, as need add the PROCESS FOR TREATMENT of waterproof with AD590 or LM35, comparatively complicated;
6) response speed is fast: because of being directly puts into water, reaction is directly contact just, so can spread out of the signal of telecommunication soon;
7) transmission performance is good: only needing three little leads just can transmit multiple spot water level and temperature, is electric potential signal because of what transmit, and electric current can be accomplished microampere order, can transmit hundreds of rice and does not influence precision, and can be easy to accomplish and computer joins guiding principle;
8) it is complete to control function automatically, simple to operate: as to set automatic loading water, stop into water automatically by temperature, water intaking valve can be used magnetic valve, or booster pump, and its function can satisfy the automation requirement of present household solar energy water heater fully, and it is simple to operate, install the back only need to connect power supply will automatic loading water, water is cut off the water after completely automatically, less than cold water in the not meeting of design temperature, making the water in the water tank all is hot water, again can automatic loading water after water uses up.
9) use the digital watch displays temperature, clear directly perceived, the resolution ratio height.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the square frame electrical schematic diagram of solar water heater water-temperature water-level display control device;
Fig. 2 is the water-temperature water-level sensor electrical schematic diagram.
The solar water heater water-temperature water-level display control device is that electric potential signal with cooling-water temperature sensor output is behind amplification and rectification circuit, by water temperature display displays temperature, simultaneous temperature setting apparatus output signal, succeed electrical equipment through on-off circuit, the electric potential signal of level sensor output is behind comparison circuit, by the water level indicator light indicated water level, go to report to the police by water level alarm, simultaneously by relay control magnetic valve or booster pump, regulate water level range by the water level settings device, water-temperature water-level sensor has voltage-stabilized power supply U, its anodal series connection has current-limiting resistance R01, R02, current-limiting resistance R01 be the proportional resistance R 1 of series connection again, R2 ... Rn, proportion resistor R1, R2 ... Rn links to each other with height level sensor contact in the water tank respectively, current-limiting resistance R02 links to each other voltage-stabilized power supply U minus earth with temperature sensing element Rt in the water tank.
Aforementioned proportion resistance R 1, R2 ... Rn is ± 1% metalfilmresistor.Temperature sensing element is silicon diode or triode PN junction.
Principle of the present utility model is: when water in the water tank and the connection of certain contact, " R1, R2 ... Rn " changes with the ratio of R01 line, the R01 line just can be exported different potential difference signals, this signal and water level become corresponding relation after relatively amplifying, and the water level value that therefore can convert correspondence to shows.When the temperature in the water tank changed, the Rt temperature sensor can produce the signal of telecommunication with temperature line relationship, and this signal of telecommunication can show corresponding temperature value after shaping is amplified in the output of R02 line.
