According to an embodiment of the present invention, the first detecting electrode 108 and the second detecting electrode 109 are fixedly connected to the flange of the heating device 104 in the inner container 102.

As an alternative example, the length of the first and

second detection electrodes

108 and 109 soaked in water may be 5-15mm, and the interval between the first and

second detection electrodes

108 and 109 may be 4-8 mm. The first detecting electrode 108 and the second detecting electrode 109 may be made of corrosion-resistant conductive metal, and may be made of titanium wire.

According to an embodiment of the present invention, the ends 401 of the first detecting electrode 108 and the second detecting electrode 109 are connected to a power source U1, wherein the power source U1 is used for supplying power to the first detecting electrode 108 and the second detecting electrode 109, so that the detecting device 106 detects the water quality in the inner container 102 through the first detecting electrode 108 and the second detecting electrode 109.

It should be noted that the first resistor R1 and the second resistor R2 are used to protect the current detection unit a1, prevent the current detection unit a1 from being burned out due to the excessive current generated in the current detection unit a1 caused by the excessively small resistance between the first motor 108 and the second electrode 109, and reduce the potential difference between the first detection electrode 108 and the second detection electrode 109, so as to slow down the speed of the scale generation on the first detection electrode 108 and the second detection electrode 109, and due to the potential difference between the first detection electrode 108 and the second detection electrode 109, the scale forming ions in the inner container 102 will be gathered to the low potential, so that the scale is generated on the detection electrode at the low potential, and the first resistor R1 and the second resistor R2 can reduce the current in the detection loop, so that the potential difference between the first detection electrode 108 and the second detection electrode 109 is reduced.

The working principle of the detection device 106 is explained in connection with the embodiment of fig. 4: the power source U1 supplies power to the first detecting electrode 108 and the second detecting electrode 109, a resistor with fixed resistance (such as the first resistor R1) and a current detecting unit A1 (such as an ammeter) are arranged in a loop formed by the power source U1 and the first detecting electrode 108 and the second detecting electrode 19, when the first and second detecting

electrodes

108 and 109 are placed in water, since conductive ions exist in the water, the conductive detection electrode can conduct electricity and has a resistance, when the water quality is different and the reading I of an ammeter is different when the power supply voltage of the power supply U1 is constant, at the moment, the voltage between the first detection electrode 108 and the second detection electrode 19 can be obtained by subtracting the divided voltage Uf (Uf ═ I R1) occupied by the first resistor R1 from the power supply voltage of the power supply U1, the resistance Rx of the aqueous solution tested by the testing device 106 can be calculated from R ═ U/I, (U-U1)/I, and the conductivity S and TDS values can be calculated.

Specifically, in the water quality detection stage, a direct current voltage is applied between the first detection electrode 108 and the second detection electrode 109 through the power supply U1, and the control device 107 can calculate the resistance value of the aqueous solution between the first detection electrode 108 and the second detection electrode 109 according to the power supply voltage of the power supply U1 and the current detected by the current detection unit a1, and obtain the water quality detection value of the aqueous solution in the inner container 102 according to the resistance value of the aqueous solution.

As described above, the first detecting electrode 108 and the second detecting electrode 109 are powered by the power source U1, the water in the inner container 102 generates a current, and after the current detecting unit a1 detects the current value, the resistance value of the water solution in the inner container 102 can be calculated according to the voltage between the first detecting electrode 108 and the second detecting electrode 109, wherein the partial voltage occupied between the first detecting electrode 108 and the second detecting electrode 109 is obtained by subtracting the partial voltage occupied by the first resistor R1 and/or the second resistor R2 from the voltage of the power source U1, the partial voltage occupied by the first resistor R1 is obtained by multiplying the self resistance value by the measured current value of the current detecting unit a1, and the partial voltage occupied by the second resistor R2 is obtained by multiplying the self resistance value by the measured current value of the current detecting unit a 1.

As an example, the power supply U1 may be provided integrally with the control device 107, for example, the power supply U1 may include a power conversion unit for converting an external power supply to a desired voltage.

According to an embodiment of the present invention, the control device 107 can also control the detection device 106 to intermittently perform water quality detection on the water in the inner container 102, specifically, the control device 107 can control the power source U1 to intermittently apply the dc voltage between the first detection electrode 108 and the second detection electrode 109 at a preset period, wherein the preset period includes an on time and an off time.

For example, the power-on time is T1 and the power-off time is T2 within a preset period, such that the power is applied intermittently, thereby allowing the detection device 106 to operate intermittently. If T1 is 2min and T2 is 8min, the running water quality detection can be realized for 2min, and the water quality detection is stopped for 8 min.

And the control device 107 is also used for determining that the water heater is in a non-water quality detection stage, and switching the polarities of the first detection electrode 108 and the second detection electrode 109 so that the current polarity of the first detection electrode 108 is opposite to the polarity of the first detection electrode 108 in the water quality detection stage, and the current polarity of the second detection electrode 109 is opposite to the polarity of the second detection electrode 109 in the water quality detection stage.

Specifically, the control device 107 may switch the polarities of the first detection electrode 108 and the second detection electrode 109 by the switching device during the non-water quality detection stage, so that the first detection electrode 108 is connected to the negative electrode of the power supply U1, and the second detection electrode 109 is connected to the positive electrode of the power supply U1.

It can be understood that when the polarities of the first detection electrode 108 and the second detection electrode 109 are interchanged, the second detection electrode 109, which is originally at the low potential, is at the high potential, and the scale attached to the second detection electrode 109 is decomposed and accumulated toward the first detection electrode 108, which is at the low potential, so as to perform a function of removing the scale.

In the embodiment of the present invention, the intermittent operation mode or the reverse treatment mode may be used alone, or the intermittent operation mode and the reverse treatment mode may be used simultaneously, for example, in the case of simultaneous use, the intermittent operation mode may be used in the water quality detection stage, and the reverse treatment mode may be used in the non-water quality detection stage. In other examples, assuming that the water quality detection stage uses an intermittent operation mode, a reverse processing mode may be used during the power-off time of at least one cycle.

Therefore, by adopting the intermittent operation, the possibility of scale generation is reduced, and in the time period without water quality detection, the reversed polarity treatment can be carried out, namely the polarities of the two electrodes are reversed, the scale attached to the surfaces of the electrodes is removed, the scale inhibition effect is realized, and the service life of the electrodes can be further prolonged.

The control device 107 can display the water quality detection value through the display device and send out a prompt when detecting that the water quality detection value is greater than the preset water quality threshold value. The user, upon seeing the reminder, may choose to drain.

Wherein, the control device 107 can be connected with the pollution discharge control device 602 and the water inlet control device 603 to control the pollution discharge control device 602 and the water inlet control device 603 to be opened or closed.

That is, the water inlet control device 603 and the pollution discharge control device 602 may be automatic control valves, and may be opened or closed under the control of the control device 107.

It should be understood that when the user sees the TDS value detected by the water heater and determines that the water heater needs to be cleaned by discharging sewage, the user can press the sewage discharging button, and after the sewage discharging button is pressed, the control device 107 receives the sewage discharging instruction, turns off the water inlet control device 603, and turns on the sewage discharging control device 602, so that the sewage in the liner is automatically discharged,
