Q:Where does the standard of the power cord length of electric kettle be measured?

First of all, teach you a little common sense of using electricity:1, household appliances are generally single-phase power supply, that is, 220v;2, the so-called single-phase power supply by a phase line L (commonly known as FireWire), a zero line N, a ground wire composition, but also by the phase line and zero line composed of two single-phase power supply;3, some household appliances have required grounding wire, such as washing machines, etc.;4, the so-called ground wire is to prevent leakage of the accident release, in the electrical shell connected to a wire into the ground, now multi-purpose leakage protector.

Q:Stainless steel electric kettle how to remove scale ah?

Vinegar descalingThis method is the most simple and practical, is the scale of the main components such as calcium carbonate carbonate, acetic acid in vinegar will reacts to produce water-soluble substances minerals and carbon dioxide gas, the general supermarkets can buy white vinegar into the kettle scale 10% white vinegar, then with water, boil a an hour, and then wash it, vinegar can also, but the effect is not good vinegar vinegar.

Q:Principle of preventing dry boil of electric kettle

The principle of bimetallic plate is that 2 different temperature coefficients of metal processing together, the higher the temperature, the 2 metal deformation difference is bigger, deformation to a certain extent, the pressure to the circuit switch.

Q:What is the structure of an electric kettle?

The electric kettle is energized after about 5 minutes, the water temperature gradually increased to 100 degrees, the water begins to boil, the bimetal steam steam impingement on the switch, due to thermal expansion and contraction function, double sheet metal expansion deformation, the top opening of the switch contacts disconnect the power supply. If the steam switch failure, the water in the kettle will always burn down, until the water is boiled, the sharp rise in the temperature of the heating element, heating plate at the bottom of the two double metal sheet, because of the effect of heat conduction temperature rise sharply, swelling deformation, disconnect the power supply. Therefore, the electric kettle safety protection device is designed, very scientific and reliable. This is the electric kettle three heavy safety protection principle.

Q:Must the electric kettle be filled with water?

Proper use and maintenance of electric kettles(1) the liquid injected into the pot shall be at least several millimeters higher than the top surface of the heater, but shall not exceed the required maximum water level.(2) when using, must install water first, after electrify, must not electrify first, after installing water.(3) do not use electric kettle to boil things with acid, alkali and salt so as not to corrode kettle body and heater.(4) when using, often remove the scale or other stains on the electric heater, otherwise it will affect the thermal efficiency and life of the electric heater.

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:A five hole socket, a socket, computer, electric kettle, electric heater can be together with you

Socket is not important, it is important that your line says how thick, the outlet should have the maximum power, the line will also have, but China's hardware and electrical appliances, many things are virtual, not credible.

Q:Electric kettle boil water, hot forgot to take after, and so on after the water cool and automatic heating, what is the matter?

Normal, general electric kettle has a steam switch and the bottom of the kettle inside a temperature control switch, when the water is boiling steam switch off automatically, if the water is dried and the water temperature drops to a certain temperature under the pot temperature control switch will automatically power off and open.

Q:Electric kettle of food grade stainless steel and 304 stainless steel kind?

Food grade stainless steel which are consistent with the "People's Republic of China national standard / stainless steel sanitary standards" provisions of GB 9684 stainless steel material, the lead content of chrome is much lower than the general to stainless steel.304 stainless steel is a very common stainless steel, the industry is also called 18/8 stainless steel. Its corrosion resistance is better than 430 stainless iron, corrosion resistance, high temperature resistance, good processing performance, so widely used in industry and furniture decoration industry and food and medical industry.

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.
