The specific embodiment
In the accompanying drawings, numbering 1 all refers to a kind of water heater of preferably storage-type, it comprises a water tank 2 and a flange 3, it disposes one or more resistors 4, and comprises that one or more sensors 6.1 or 6.2 and 6.3 are in order to read the water temperature in the described water tank and to transmit signal to the sleeve pipe 5 (being generally a kind of electronic installation) of device 6 and anticorrosion device 7 preferably at last.
According to the present invention, during heating, the lime scale that occurs on resistor 4 can read by adopting respectively from the temperature data t6.1 of described sensor 6.1 or 6.2 and 6.3 or t6.2 and t6.3.
Best is, described sensor 6.1 or 6.2 with 6.3 with described water heater thermostat adopt the sort of identical, it is necessary for electron type in this case; Be more preferably, according to the present invention, determine a kind of single-electron device, it can be at the formation of lime scale and sends signal, also carries out such as constant temperature simultaneously and/or calculates the hot water amount and/or send the function of water temperature signal.
According to first embodiment, the layout drawing that reaches among Fig. 2 among Fig. 4 is depicted as definite a kind of single temperature sensor 6.1 that is arranged near resistor 4.
Judgement according to those skilled in the art, it should be noted that, " approaching " speech is interpreted as the distance between described resistor 4 and described single temperature sensor 6.1, it is like this, it is just begun forms, but the thickness lime scale before that arrives the damage that causes irreparability covers.
For an example, in the family expenses water heater, described distance was lacked 60mm and was more preferably and lacked 50mm, even was more preferably and lacked 40mm.
Described sensor 6.1 preferably is arranged at the height of low described resistor 4 maximum heights; Yet it can be arranged on the height that exceeds described resistor 4, and condition is that this height can begin to form in lime scale, but reaches before the damage that causes irreparability
Below will make more detailed explanation, the temperature data t6.1 that reads by sensor 6.1 can compare with the thickness relevant for the lime scale that forms on resistor 4.
For this purpose, described device 6 comprises a kind of in order to judge near the water firing rate G1f of resistor 4 and with described firing rate and reference value calculating device 6.4 (simulation or data) relatively.
Described reference value is preferably based on relevant for reference firing rate G10, and it meets the firing rate that obtains under lime scale or the low-down lime scale level not having.
Described with reference to the kind of firing rate G10, and more particularly according to water heater, be to change according to installation power and geometry.
Each described firing rate G1f surpasses described during with reference to firing rate G10 threshold value Δ G, and just this is regarded as enough thickly formed lime scale, need keep in repair.
The speed of measuring is fast more, and is just big more by being arranged at temperature t 6.1 and the gap between the actual water temperature in the described water heater measured near the temperature sensor 6.1 of resistor 4.
Therefore, the growth of lime scale is in heating during back first minute, do not having lime scale or by measuring when lime scale is very slight with meeting, and the reference firing rate G10 of the firing rate that obtains compares and calculates near the actual firing rate G1f of described resistor 4 and with this speed.
Shown in Fig. 5 being one does not have the calculus black dirt and uses water heater after 27 days, reads the example that temperature rises by the probe that approaches described resistor.
After described water heater was brought into use, lime precipitation was on described resistor subsequently in case reach, and described firing rate just can thereby increase.
Preferably also can determine to use other device to allow that with storage and/or adjustment the user presets or revise the reference firing rate G10 of described speed.
In beginning just between installation period, provide to store described device with reference to firing rate G10, described can also self-control with reference to firing rate G10.
Described threshold value Δ G changes with the type of using water heater, and during use, it can be preset or revise, and in more general type, its numerical value is between 3 to 5 ℃/minute.
According to a kind of preferable operator scheme, described firing rate is perhaps measured when water temperature reaches 30 ℃ in the predetermined time interval that is no more than 5 minutes.
In fact, have and do not have the main reading difference between the heating curves that lkd layer occurs can reach about 30 ℃ of temperature, it reached in 5 minutes basically.
When surpassing predetermined reference firing rate G10 threshold value Δ G near the firing rate G1f of described resistor, perhaps, in other words, when lime scale is enough thick when need keep in repair, predicting has vision and/or audible signal as alarm.

The first sensor 6.2 that is used to measure temperature T 1 is disposed in the heating region, perhaps with the same terms of first embodiment explanation under, be disposed in the zone of a little higher than described heating region.
Even described second sensor 6.3 is disposed at apart from the position of described resistor distance so that energy measurement has the actual temperature T2 of the heating water capacity of lime scale existence.
For this reason, described second sensor 6.3 is disposed at substantially apart from described resistor 4 100mm at least, and best 150mm at least.
By described sensor 6.2 and the 6.3 couples of thermograde T1-T2 that read can be relevant with lime scale thickness relatively.
Fig. 5 and 6 be shown as when described resistance under brand-new state, and after having used 130 days, the example that rises of the temperature that reads by described two temperatures probe and described thermograde progress T1-T2 respectively.
Use after the described water heater, and cause that also lime scale gathers on described resistor, described thermograde T1-T2 then increases thereupon.
For this purpose, described device 6 comprises calculating device 6.4 (simulation or data), and it reaches this thermograde and reference gradient Δ T0 are compared near described two sensors and accurately at one time in order to measure the thermograde T1-T2 of described water.
Described reference gradient Δ T0 becomes with the type of water heater, and specifically, become with installation power and geometrization, and give be limited with about do not have or situation that considerably less lime forms under.
For more common type, described reference gradient Δ T0 is in 20 to 30 ℃ of scopes.
Preferably provide device to be used for storing and/or regulating described reference gradient Δ T0, it can make the user preset and/or revise described gradient.
Between initial installation period, the device that can store described reference gradient is provided, described reference gradient Δ T0 can also self-control.
When at every turn the thermograde T1-T2 through measuring surpassed described predetermined reference gradient delta T0, the lime scale of formation then was enough to lower the efficient of described water heater, and therefore, described water heater just need keep in repair.
Described predetermined reference gradient is preferably at whole period of heating of measurements, and is more preferably, and is no more than in 5 minutes in heat time heating time, perhaps meets in described resistor 6.2 does not exceed time of 30 ℃.
If when the reading of described reference gradient Δ T0 surpassed, the formation of superfluous lime scale was then sent signal by the mode of vision and/or audible signal.
Propose display showing described firing rate or describedly to add how time to time change of thermal gradient, and make described user can be controlled at the formation of lime scale on the described resistor.
Except that vision and/or audible signal send the signal, described water heater can also provide a kind of system so that transfer the state of shutting to.
