Q:What are the problems with electric kettles in the market?

The plastic material does not use qualified food grade products, open the lid of a plastic taste

Q:How to judge whether the electric heating pipe of electric kettle is damaged?

It's OK to use a multimeterExpress it to DCIf only it would be readyI've been studying appliance / refrigeration for 2 years

Q:How can I see the qualified product in the kettle itself?

Look at the appearance. The plastic is thick and relatively smooth and bright and beautiful appearance. The purchase should pay special attention to the seal condition, there should be no leakage phenomenon Water Leakage. If the heating element can be seen, attention to buy the heating element and the kettle body interface should be installed firmly and reliable seal, hand gently touch the heating element, the check assembly is strong, should not have loose phenomenon.

Q:Taobao sell electric kettle business a lot of ah, the price is also very chaotic, we recommend an affordable electric kettle bar, the first shopping, dare not casually start Oh ~ thank you!

To Tmall mall to buy, quality guaranteed

Q:How do you remove the water stains from the electric kettle?

Baking soda descalingGeneral electric kettle heating plate is made of aluminum, in the kettle, it is easy to form scale, we can put 1 teaspoon of baking soda, boil a few minutes apart from the scale. Or you can pour about 1% grams of soda water about 500 grams, gently shake rinse, scale can be removed.

Q:How to get rid of the kettle rust, that piece of water, there is a brush and brush off, usually

Put the vinegar on the hot water. After that, every day in the kettle, you don't have a thin gauze!

Q:Why doesn't the electric kettle open automatically when the lid is opened?

Principle of automatic power-off of electric kettle:Automatic power-off function is located inside the cup handle (upper, windpipe or the bottom of the cup, this time need a longer the temperature controller) double sheet metal in the form of implementation, and no relay, the thermistor inside, it is a feeling of steam temperature, so the indirect comparison, generally is the breaking point of water after boiling steam temperature to achieve temperature controller. So if you open the lid and boil the water, it won't automatically break.

Q:Why is the electric kettle automatically power-off after the water is opened?

According to the principle of thermal expansion and contraction of object. Thermal expansion and contraction are the general characteristics of objects, but the degree of thermal expansion and contraction of different objects is different. With metal sheet copper made into contact. Because of thermal expansion and contraction of copper sensitive so in the temperature does not reach the set value of the copper, the metal plate is a curved shape, when the contact is closed. In the water is heated to a temperature of the water when the heat conduction to the copper copper thermostat in the above because the heat will play into contact with the off state. When the temperature drop of copper restored to the original state of the contact switch into electrical heating state. Two double gold sheet is a conductor of different substances, changes in temperature due to expansion is not the same degree of the dual metal sheet bending, meet or contact the switch is set, so that the set circuit starts to work. This is more direct and timely, accurate induction of water temperature.

Q:Why doesn't an electric kettle touch an electric shock when you work?

When the kettle work is on the current through the resistance wire and heat resistance to open water so it is not very well insulated shell resistance wire and the fixed contact kettle it is some of the insulation material temperature, of course, also may shock is also called leakage but does not affect its efficiency.

Q:Electric kettle can not automatically power-off

This kind of temperature control switch is sold in the general household electrical appliance fittings shop or the electrical appliance repair point, and it is about 5-10 yuan. Purchase must buy the same switch, not higher or lower than the original temperature, otherwise the water did not open or not jump.
