Description
Technical field
The invention belongs to laundry care machine field, particularly relate to the method and laundry care machine that prevent the galvanic corrosion of laundry care machine calorifier.
Background technology
The principle of heating of laundry care machine is the heat energy converting electrical energy into water, and it carries out heating water specifically by metal calorifier.The metal calorifier of laundry care machine in use for some time, easily generates incrustation scale, and in order to prevent the generation of incrustation scale, prior art provides following three kinds of methods:
1) ion exchange method, the method specifically comprises two kinds of embodiments, a kind of mode is adopt the calcium ions and magnesium ions in sodium ion exchange resin and water to react, like this, can fast by the calcium ions and magnesium ions in sodium ion exchange to water and in planar water, thus can reach the hard water thoroughly softening object becoming the water not having calcium ions and magnesium ions; Another kind of mode is adopt the part calcium ions and magnesium ions in hydrogen ion exchange resin and water to react, thus can reach the appropriate object reducing water hardness, and which while appropriate calcium ions and magnesium ions, can make can not remain incrustation scale again in boiled water in reservation water.
2) physical filtering method, the method be specially using the pressure higher than osmotic pressure as impellent and utilize the selective penetrated property of selective membrane make water through and make the impervious mode of solute from water body, extract the membrane separating process of fresh water.
3) method of chemical treatment, the method is specially and adopts Si-P crystal or the chemical agent such as sodium hydroxide or tertiary sodium phosphate to carry out preventing incrustation scale from producing or suppressing its deposition growing.
Aforesaid method all effectively can prevent the generation of incrustation scale, but, the metal calorifier of existing laundry care machine still Shortcomings part in a particular application, particular embodiment is as follows: the metal calorifier of current laundry care machine is made primarily of aluminium or the comparatively active metallic substance such as iron or copper, in wet condition, the moisture film of one deck conduction can be adhered in aluminium or the metallic surface such as iron or copper, like this, make between the metallic surface of metal calorifier and self impurity, to form many small galvanic cells, thus result in the generation of metal calorifier galvanic corrosion phenomenon, and the above-mentioned measure preventing incrustation scale from generating can not prevent the generation of metal calorifier galvanic corrosion phenomenon, and then (corrosion of aluminium matter calorifier produces oxyhydroxide to make metal calorifier generate a large amount of rust deposites within the extremely short time, the corrosion of irony calorifier produces iron rust, copper calorifier corrosion produces ventilation breather), and at use initial stage of these laundry care machines, the embroidery dirt that galvanic corrosion produces is often even more serious than the incrustation scale stayed after water evaporation, and then the life-span of metal calorifier and performance are had a strong impact on.
