In the present embodiment, material used in the water inlet pipe 10 of water heater is based on phosphorized copper (TP2).Made of the material
Water lines are easy that electrochemical corrosion occurs with the bold and vigorous ion of the ratio work in copper in tap water in use, while each area water
The various metals and nonmetallic ion contained in matter are more and more, such as Cl-、Ca2+、Mg2+、Na-、SO4 2-、NO3-Plasma accelerates
The electrochemical corrosion of the inlet pipeline component of water heater, seriously will lead to the inlet pipeline leak of water heater, makes water heater not
It can use, influence service life of a machine.
The present embodiment, water flow sensor 20 is arranged on water inlet pipe 10, for monitoring flow of inlet water.Water flow enters water flow
The path that water inlet pipe 10 is continued on after quantity sensor 20, which is flowed and enters the heat exchanging pipe of heat exchanger 40, to be heated, most final temperature
Degree, which increases, becomes hot water outflow water heater.Magnesium metal structure 21 is built-in in water flow sensor 20, detection device 30 is electrically connected
Between magnesium metal structure 21 and water inlet pipe outer wall.It is appreciated that the side connecting pin of magnesium metal structure 21 is worn after sealing
The tube wall of water inlet pipe 10 is crossed, and is electrically connected with outer lead, then is electrically connected by detection device 30 with the outer wall of water inlet pipe 10.
Specifically, increase the magnesium metal structure 21 stronger than copper metal activity in the water flow sensor 20 of water heater,
The outer wall of magnesium metal structure 21 and water inlet pipe 10 is electrically connected, water inlet pipe 10, magnesium metal structure 21 and water three made of copper can be made
Person forms primary battery device.Using the metal activity of magnesium metal structure 21 characteristic stronger than the metal activity of copper, in former electricity
So that magnesium metal structure 21 is lost electronics in pool device, oxidation reaction occurs and protects copper, reduction reaction occurs for copper, reduces water inlet pipe 10
Be etched electrochemically the risk of leak, to promote reliability and the service life of water heater.In addition, in magnesium metal structure 21
The current potential of magnesium is usually -2.34V, and the current potential of the copper for pipe outer wall of intaking is usually 0.34V, magnesium metal structure 21 and water inlet pipe outer wall
Between potential difference can also provide power supply and electric signal for water flow sensor 20.
On the other hand, in primary battery device, magnesium metal structure 21 is equivalent to anode, and water inlet pipe 10 is that copper pipe road is equivalent to
Cathode, it is substantially to lose electronics i.e. consumable anode that oxidation reaction, which occurs, for magnesium metal structure 21, wherein anode: Mg-e-=Mg3+, copper
It is the electronics for obtaining magnesium metal and losing that reduction reaction, which occurs, for pipeline, wherein cathode: Cu2++e-=Cu.In this way, magnesium loses as anode
De-electromation, copper pipe road obtain the electronics that magnesium loses as cathode, the copper pipe road of water heater can be made not to be corroded, to protect hot water
The copper pipe road of device can operate normally for a long time, increase water heater service life.However, oxidation reaction occurs for magnesium metal structure 21
Essence is to lose electronics i.e. consumable anode, and 21 long-time of magnesium metal structure may face the case where being depleted after being consumed, this
When just need replacing magnesium metal structure 21, otherwise influence water heater service life.

Often be 0.34V, magnesium metal structure 21 and water inlet pipe outer wall between potential difference make magnesium metal structure 21 and intake pipe outer wall it
Between have electric current flowing, specifically, electric current flows to magnesium metal structure 21 by resistance 31 from water inlet pipe outer wall.Amplifier module 32 and electricity
Resistance 31 is in parallel, flows through a certain amount of electric current on the path of resistance 31 in parallel, and the amplifier module 32 in device 30 is amplified after testing
After current signal can be obtained.It is appreciated that the current signal for flowing through resistance 31 that amplifier module 32 obtains substantially is amplifier module
32 pairs of current signals for flowing through resistance 31 amplify rear acquired current signal.Amplifier module 32 is by the amplified electric current
Signal is transmitted to processing module 33.
It should be noted that the current potential of magnesium metal structure 21 increases after magnesium metal structure 21 is with lasting consumption is used,
Potential difference between water inlet pipe outer wall is smaller and smaller, and the current signal for flowing through resistance 31 accordingly is smaller and smaller.By convection current
The detection of the size of current signal through resistance 31 may determine that the Expenditure Levels of magnesium metal structure 21.Specifically, detection device
Minimal Protective current value is provided in 30, which, which is magnesium metal structure 21, needs more reaching threshold value
The current signal of resistance 31 is flowed through when changing, Minimal Protective current value can pass through test of many times according to the material and length of inlet pipeline
Determine size.
Wherein, when the current signal that amplifier module 32 obtains is less than Minimal Protective current value, illustrate that magnesium metal structure 21 needs
It replaces, if replacing not in time, the effect on protection copper pipe road will not be played；Amplifier module 32 obtain current signal be greater than or
When equal to Minimal Protective current value, illustrate that no replacement is required for magnesium metal structure 21, continues to consume magnesium metal structure 21, be still able to
To the effect on protection copper pipe road.Based on this, processing module 33 can detect the current signal of the transmission of amplifier module 32, and detect
Replacement magnesium information is generated when current signal is less than Minimal Protective current value and is exported, and magnesium metal structure is needed replacing after to inform
21.Such detection device 30 realizes the detection to magnesium metal structure 21.It should be noted that processing module 33 can be integrated in inspection
It surveys in device 30, can also be integrated in the main controller of water heater, as long as can be realized the function of processing module 33, not limit place
Manage the setting position of module 33.
In the present embodiment, the detection device of water heater is connected electrically between magnesium metal structure and water inlet pipe outer wall；Detection dress
Set resistance, amplifier module and processing module including being connected on magnesium metal structure between pipe outer wall of intaking.In the present embodiment, inspection
It surveys device and the current signal for flowing through resistance is obtained and amplified by amplifier module, whether its current signal is judged by processing module
Less than Minimal Protective current value, and when detecting that current signal is less than Minimal Protective current value, determine that magnesium metal structure needs
Replacement.In the present embodiment, the structure of detection device is simple and practical function, does not increase the structure of water flow sensor, realizes
Detection to the Expenditure Levels of magnesium metal structure.
Illustratively, based on the above technical solution, optionally, amplifier module 32 as shown in Figure 3 includes that filtering is single
Member.Filter unit is usually used in filtering off the ripple in rectifier output voltage.In the present embodiment, amplifier module 32 is used for current signal
It is transmitted to processing module 33, wherein there are current ripples, interference electric current signal.Based on this, increase filtering in amplifier module 32
Unit, the current signal for being transmitted to processing module 33 to amplifier module 32 are filtered, and eliminate the electric current line in current signal
Wave enhances anti-interference of the amplifier module 32 into 33 transmission process of processing module, avoids the current signal distortion of output, mentions
High testing result reliability.
It should be noted that shown in Fig. 3 be only a kind of amplifier module 32 with filter unit, amplifier mould in the present invention
