How long can a rice cooker usually last?
My rice cooker has been used for nearly 5 years, 6 years now.Well, the surface of the rice cooker is thicker and not easy to scrape.The rice cooker is made of alloy aluminum, not pure aluminum. They are anodized aluminum alloy, increasing the hardness and wear resistance of the original aluminum! The alloy is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is performed under the special conditions and the applied electric current. The anodized aluminum or its alloy is formed on the surface of alumina thin layer with a thickness of 5~20 microns and a hard anodized film of up to 60~200 microns. Anodized aluminum or aluminum alloy, improve its hardness and wear resistance, can reach 250 to 500 kg / mm2, good heat resistance, hard anodic oxidation film of high melting point of 2320K, excellent insulation, high breakdown voltage up to 2000V, enhance the corrosion resistance, salt fog after thousands of hours = 0.03NaCl no corrosion in.In fact, the general rice cooker can be used for several years, the use should pay attention to maintenance. If cooked rice is cooked, store it in other containers at night and don't put it in the pan directly. General electric rice cooker for about 5 years is no problem.
Method for prolonging service life of electric cooker:1, the bottom of the pot should avoid collision deformation. Must be kept clean between the heating plate and the inner pot, rice should not fall into the effect of thermal efficiency and even damage the heating plate.2, the pot can be washed with water, but the shell and heating plate shall not be flooded, only after cutting off the power, wipe with a damp cloth.3, should not boil acid, alkali food, also don't put in corrosive gas or damp place.4, when using, should be cooking food into the pot first, cover the lid, and then plug in the power plug; remove the food before the power plug should be pulled out to ensure safety. Packing and storage are usually placed in electric rice cooker box, lined with shockproof foam on materials, accessories in a plastic bag placed in the pot, add a large number box corrugated cartons, outer tie fastening, and requirements for marking. Each rice cooker must have a product qualification certificate and instructions for use. During transportation, the cartons should be handled with care, and the storage warehouses shall be well ventilated and free from corrosive gases.
The national standard for rice cooker is 5 years.Because of the power cord, computer motherboards, magnetic steel and other accessories in the long-term state of high temperature, long aging, prone to short-circuit and other accidents. But at present, the Chinese people in these areas is not very much attention, generally have to wait until the bad, can not be used to change the new. Conditional advice is best to use five or six years to change one.
