Description
Technical field
The invention belongs to laundry care machine field, particularly relate to prevent laundry care machine heating element electrochemical corrosion
Method and laundry care machine.
Background technology
The principle of heating of laundry care machine is the heat energy converting electrical energy into water, and it generates heat specifically by metal
Device carries out adding hot water.The metal heating element of laundry care machine in use for some time, easily generates incrustation scale,
In order to prevent the generation of incrustation scale, prior art provides following three kinds of methods:
1) ion exchange, the method specifically includes two kinds of embodiments, and a kind of mode is handed over for using sodium ion
Change resin to react with the calcium ions and magnesium ions in water, so, can be quickly by sodium ion exchange to water and adsorb
Calcium ions and magnesium ions in water, thus can reach and hard water is thoroughly softened the purpose becoming the water not having calcium ions and magnesium ions；
Another way is to use hydrogen ion exchange resin to react with the part calcium ions and magnesium ions in water, thus up to
To the appropriate purpose reducing hardness of water, which while appropriate calcium ions and magnesium ions, can make in retaining water
Boiled water will not remain incrustation scale again.
2) physical filtering method, the method is specially as motive force and to utilize choosing higher than the pressure of osmotic pressure
The selective penetrated property of selecting property film makes water pass through and makes the impervious mode of solute extract the film of fresh water from water body
Separation process.
3) method of chemical treatment, the method is specially and uses Si-P crystal or the chemical drugs such as sodium hydroxide or tertiary sodium phosphate
Agent carries out preventing incrustation scale from producing or suppressing its deposition growing.
Said method all can effectively prevent the generation of incrustation scale, but, the metal heating element of existing laundry care machine
Still suffering from weak point in a particular application, concrete embodiment is as follows: the metal heating of current laundry care machine
Device is mainly made up of the metal material that aluminum or ferrum or copper etc. are the most active, in wet condition, and aluminum or ferrum or copper
Deng metal surface can adhere to one layer conduction moisture film, so so that the metal surface of metal heating element and self
Many small galvanic elements can be constituted between impurity, thus result in metal heating element electrochemical corrosion phenomenon
Occur, and the above-mentioned measure preventing incrustation scale from generating can not prevent sending out of metal heating element electrochemical corrosion phenomenon
Raw, and then (corrosion of aluminum matter heating element is produced to make metal heating element generate substantial amounts of rust deposite within the extremely short time
Raw hydroxide, the corrosion of irony heating element produces rust, and the corrosion of copper heating element produces basic copper carbonate),
And at the use initial stage of these laundry care machines, the embroidery dirt that electrochemical corrosion produces stays after often evaporating than water
Incrustation scale even more serious, and then the life-span of metal heating element and performance are severely impacted.
Specifically, the process of aluminum matter heating element generation electrochemical corrosion is as follows:
Negative pole (Al): Al-3e-=Al3+
Positive pole (impurity): 2H++ 2e-=H2 ↑
Overall reaction: 2Al+6H2O=2Al (OH)3+3H2↑
Wherein, Al (OH)3For white flock precipitate.
The process of irony heating element generation electrochemical corrosion is as follows:
(1) gas-evolving electrodes (when steel surface adsorbed film of water acidity is stronger)
Negative pole (Fe): Fe-2e-=Fe2+
Fe2++2H2O=Fe (OH)2+2H+
Positive pole (impurity): 2H++ 2e-=H2↑
Overall reaction: Fe+2H2O=Fe (OH)2+H2↑
Owing to its corrosion process having hydrogen to release, therefore referred to as gas-evolving electrodes.
(2) oxygen uptake corrosion (when steel surface adsorbed film of water acidity is more weak)
Negative pole (Fe): Fe-2e-=Fe2+
Positive pole: O2+2H2O+4e-=4OH-
Overall reaction: 2Fe+O2+2H2O=2Fe (OH)2
Owing to its corrosion process absorbing oxygen, therefore referred to as oxygen uptake corrosion.
The Fe (OH) that gas-evolving electrodes generates with oxygen uptake corrosion2Aoxidized by oxygen, generate Fe (OH)3Dehydration generates
Fe2O3Rust, concrete reaction equation is 4Fe (OH)2+O2+2H2O=4Fe (OH)3
In concrete application, the electrochemical corrosion of irony heating element is mainly oxygen uptake corrosion.
The process of copper heating element generation electrochemical corrosion is as follows:
2Cu 4e-=2Cu2+
2H2O+O2+ 4e-=4OH-
CO2+ 2OH-=CO3 2-+H2O
Overall reaction: 2Cu+2H2O+O2+CO2=Cu2(OH)2CO3(basic copper carbonate, i.e. Aerugo).
