Description
Technical field
The utility model relates to a kind of water heater, particularly a kind of water heater that possesses anode stub consumption warning deixis.
Background technology
For electric heater, the consumption degree of anode stub, consumption speed are to influence water heater service life and user's important hidden danger safe in utilization always.The magnesium rod is a kind of of anode stub, and the magnesium rod uses as sacrificial anode in water heater.Because the metal active of magnesium is than iron height, under the situation that magnesium rod and general steel plate expose simultaneously, the magnesium rod at first replaces steel plate corrosion to fall, thereby reaches the purpose of protection inner bag.How effectively to solve the problem that anode stub consumption brings, become the important problem directly perceived of electric heater development.When magnesium rod approach exhaustion, it is particularly serious that the fouling of water heater just becomes, in case and fouling, damage that water heater is caused and the potential safety hazard of bringing are very serious.Dirt is hard as calculus, and it is very poor to transmit the ability of heat, only reach irony or glass 1% less than, these dirts can be on the increase, can the many adverse consequences of generation in the use of water heater:
A makes the caloric receptivity deficiency of water, and the temperature of water is difficult to raise, the electricity charge of waste about 30%.By the 30 yuan of calculating of need of heating up water in every month, about 10 yuan were wasted.
B is difficult to detect the signal of water temperature and water level because probe is wrapped up by incrustation scale, easily causes maloperation.
The electrothermal tube efficiency of heating surface of the auxiliary heating of c reduces.Because electrothermal tube is wrapped up by incrustation scale, heat distributes and does not go out, and heat is too high in causing, and often blows heating wire or hardening cracks the electric heating pipe box, causes danger easily, has to often change.Anode stub also can make metal covering enrichment and produce the chemical attack reaction under dirt such as some corrosion component in the water such as H+, OH-, Cl-, Mg2+, S2-.The result of corrosion is that localized metallic is damaged attenuate, and corrosion can reach and penetrate the equipment steel plate, the degree that makes equipment leakage, breakage even lost efficacy.Thereby the maintenance of equipment expense is increased.During seriously corroded, equipment is scrapped in advance.
The d internal diameter of the pipeline attenuates.Because the incrustation scale of knot stops in the pipeline, makes current not smooth.All above-mentioned faults can make the serviceability of water heater have a greatly reduced quality, and cause great inconvenience and trouble to the user.
The e incrustation scale is to the harm of health.Tartar, periodontitis often are to be caused by incrustation scale.Can cause the people desperately still do not have the preventible Legionella bacteria of vaccine so far, just conceal in incrustation scale, annual in the world about 150,000 people die from this germ, anode stub also is very serious for the injury of user's human body.

In the more further preferred version that the utility model provides: described single-chip microcomputer IC is in each cycle, repeatedly read water quality signal and temperature compensation signal, average by described accumulation computing module after the temperature compensated computing, described accumulation computing module is accumulated stack to the mean value in each cycle, the signal that the output of described single-chip microcomputer will be accumulated stack exports described warning indicator to, by the form demonstration accumulation stack amount of described warning indicator, come the accumulation of the anode stub of display water heater to consume situation with this with block diagram or cake chart.
Described accumulation computing module is provided with a reference value, when described accumulation superposition value during more than or equal to described a reference value, the output of described single-chip microcomputer outputs control signals to described warning indicator, makes the block diagram of described warning indicator or cake chart by red display, and/or sends sound and light alarm.When described accumulation superposition value during more than or equal to described a reference value, the accumulation stack computing of next round is carried out in described single-chip microcomputer IC zero clearing.
Single-chip microcomputer repeatedly reads the water quality signal in each cycle, and averages, and accumulates stack with the mean value in each cycle then.Cycle can be 1 month, can divide in 1 month cycle and read the water quality signal 4 times, gets the mean value of 4 water quality signals during to the end of month, and every month mean value is accumulated stack.Make dynamic monitoring more accurate like this, avoid water quality environment to change the detection error of bringing, make the consumption monitoring of anode stub more accurate.Can come the adjustment cycle time according to the situation of various places, 1 month or 1 season or half a year are one-period.Cycle is short more, and the error that change of water quality is caused is just more little, and the monitoring accuracy that water quality detection and anode stub consume is just higher.
The utility model also provides another kind of scheme, described single-chip microcomputer IC also comprises comparison module, value and the preset reference value of described comparison module after to compensation operation compares: the value relatively is greater than a, then timing module started for first time-count cycle, and the timing time of described first time-count cycle is J; Or the value relatively more than or equal to b smaller or equal to a, then timing module started for second time-count cycle, the timing time of described second time-count cycle is K; Or the value relatively is less than b, then timing module started for the 3rd time-count cycle, the timing time of described the 3rd time-count cycle is L, described J＞K＞L, output by described single-chip microcomputer after described first time-count cycle or second time-count cycle or timing the 3rd time-count cycle are finished outputs control signals to described warning indicator startup work, reminds the anode stub of user's water heater to consume situation.
Wherein said a reference value is constant according to the area and the relative distance of first detecting electrode in the water quality sensor and second detecting electrode, under the constant situation of the resistance of first resistance R 1, and the data that draw by test of many times, test.This a reference value has reflected benchmark that anode stub consumption in the water heater is whether serious, when the value after the temperature compensated computing and this a reference value relatively after, its result's difference has then been reacted the actual water quality quality and the consumption degree of water heater anode stub accordingly.Different correspondences as a result different timing circuits, start the timing circuit timing, after timing is finished, start warning indicator and remind the present water quality situation of user, and consume degree at the present anode stub of this water quality situation lower water-heater.In the present embodiment, the value after the temperature compensated computing and described a reference value result relatively, if its voltage below 1V, then timing module started for first time-count cycle, the timing time of described first time-count cycle is between 2 years to 3 years; If or its voltage is between 1V to 2V, then timing module started for second time-count cycle, and the timing time of described second time-count cycle is between 1 year to 2 years; If or its voltage is more than 2V, then timing module started for the 3rd time-count cycle, and the timing time of described the 3rd time-count cycle is in 1 year.
As shown in Figure 3, described signal pre-processing circuit comprises the water quality detection circuit, temperature-compensation circuit, described water quality detection circuit detects the resistance signal of water and changes voltage signal into by water quality sensor R and inputs to described signaling conversion circuit, and described temperature-compensation circuit detects the temperature signal of water and changes voltage signal into by described temperature sensor RT and inputs to described signaling conversion circuit.
Described testing circuit also comprises first resistance R 1, one end ground connection of described first resistance R 1, the end of described water quality sensor R is connected with Vcc, and the other end of the other end of described first resistance R 1 and described water quality sensor R together inserts No. 1 input port of described single-chip microcomputer IC.Described temperature-compensation circuit also comprises second resistance R 2 and first capacitor C 1, described second resistance R 2 and 1 parallel connection of described first capacitor C, and the end after the parallel connection links to each other with Vcc, common No. 2 input ports that insert described single-chip microcomputer IC of the end of the other end and described temperature sensor RT, the other end ground connection of described temperature sensor RT.Described alert circuit comprises light-emitting diode display, and described light-emitting diode display and described single-chip microcomputer IC No. 3, No. 4 link to each other with No. 5 output ports.
When water quality was good, the resistance of water quality sensor R was bigger, and Vcc is by the dividing potential drop of the water quality sensor R and first resistance R 1, and is lower at the voltage of single-chip microcomputer IC1 input port; When water quality bad time, the resistance of water quality sensor R is less, and Vcc is by the dividing potential drop of the water quality sensor R and first resistance R 1, and is higher at the voltage of No. 1 input port of single-chip microcomputer IC.The i.e. lower voltage of water quality correspondence preferably, the corresponding higher voltage of relatively poor water quality.When water temperature was higher, the resistance of temperature sensor RT was less, and Vcc is by the dividing potential drop of second resistance R 2 and temperature sensor RT, and is less at the voltage of No. 2 input ports of single-chip microcomputer IC; When water temperature was low, the resistance of temperature sensor RT was bigger, and Vcc is by the dividing potential drop of second resistance R 2 and temperature sensor RT, and is bigger at the voltage of No. 2 end inbound ports of single-chip microcomputer IC.First capacitor C 1 is done filtering and is used.The higher lower voltage of temperature correspondence.Analog to digital conversion circuit among the single-chip microcomputer IC carries out analog-to-digital conversion to the signal of No. 1 input port and No. 2 input port inputs, the temperature-compensating computing is carried out by temperature compensation module in the conversion back, the value after the temperature-compensating computing and a reference value of setting are compared by comparison module, start corresponding timing circuit timing according to different comparative results, start led pipe corresponding in the alert circuit after timing is finished and light, remind the anode stub of the present water heater of user to consume degree.
When water quality was relatively poor, in the short period of time such as 2 years, the full level of single-chip microcomputer delivery outlet 3 that makes after 2 years of timing was uprised by low, extinguishes (or lighting) first LED pipe; After first LED pipe extinguished (or lighting), the single-chip microcomputer zero clearing was relatively judged again, if relatively the water quality as a result of Pan Duaning is still relatively poor, then extinguished (or lighting) second LED such as 1 year in the short period of time and managed; After second LED pipe extinguished (or lighting), single-chip microcomputer is zero clearing once more, relatively judged again, if water quality is also relatively poor, then extinguished (or lighting) the 3rd LED pipe in the short period of time within 1 year.When three LED pipes all extinguish (or lighting), illustrate that the anode stub consumption degree of water heater liner is very serious, face anode stub with the wind direction that runs out of, the caution user need change anode stub, and needs to clean water heater.Better when water quality, such as 3 years, the full level of single-chip microcomputer delivery outlet 3 that makes after 3 years of timing was uprised by low, extinguishes (or lighting) first LED pipe in the long time; If water quality still is relatively good, the level that then makes single-chip microcomputer delivery outlet 4 from low to high, in the long time such as 2 years, full (or lighting) second the LED pipe that extinguish after 2 years of timing, and the like, until extinguishing (or lighting) the 3rd LED pipe, compare water quality relatively poor use water environment, time limit, degree that anode stub consumes are all longer relatively, reduce the waste of manpower and financial resources.Make the consumption operating position of the present water heater anode stub of the clearer understanding of user, and whether need to change anode stub.
