The main components of scale are calcium carbonate and magnesium hydroxide, which can undergo chemical changes with acids. According to this principle, Pour some edible citric acid or citric acid scale remover into the kettle（Cooking vinegar can also be used）. Heating treatment, You can see many small bubbles, The scale quickly dissolved. The method of using vinegar to remove scale from stainless steel electric kettles is quite common. Because the main component in scale is calcium carbonate, It can react chemical

Currently, there are two types of materials for the body of electric kettle on the market: Stainless steel and polypropylene materials. The materials used in electric kettles are only inspected and certified by authoritative institutions, Those that meet these two inspection standards, It can be considered as a "healthy material". In addition, it can also be judged through the methods of "seeing" and "smelling". Food grade stainless steel generally has good glossiness, It doesn't s

Heating element    If the electric water heater is not heating, it may be due to a problem with the heater components. Domestic water heaters typically have upper and lower heating elements. If the water is not heated, It is likely that there is a problem with the upper heating element, And if there is some hot water present but not a lot, So the lower heating element is likely a problem. Multiple heating elements can be used to test the functions of heaters and instruments.Turn off the power to the wate

Structure of adjustable thermostat The adjustable thermostat includes a large body bracket, as well as a cam temperature adjustment shaft, positioning spring, large body shell, and a ceramic column. The large body shell is riveted to the large body and forms a limit cavity with the large body bracket. The cam temperature adjustment shaft is set above the limit cavity and passes down through the large body shell, and its bottom is set inside the limit cavity. One end of the ceramic column is sleeved at the bottom o

Temperature switches have the characteristics of small size, insulated housing, sensitive action, and long service life. Widely used for dual protection against overheating and overcurrent of various motors, induction cookers, vacuum cleaners, coils, transformers, electric heaters, ballasts, electric heating appliances, fluorescent lamp ballasts, automotive motors, integrated circuits, and general electrical equipment.    Matters needing attention: When using contact temperature sensing installation,

The KSD301 temperature switch is also a jump type temperature switch that we often talk about. It is mainly used to control the use process of products, and is widely used in household appliances, For example, electric rice cookers, egg cookers, coffee pots, water heaters, etc., have a simple structure and high sensitivity to temperature sensing. However, temperature switches can also fail during use. Today, we will discuss the failure of temperature control switches.   There are many reasons for t

With the gradual development of technology, household appliances are becoming increasingly diverse and intelligent, and the ultimate requirement for any type of household appliance is always safety. The temperature control switch is an important electronic component in electrical equipment, which can also be started or closed as the temperature changes during operation. The temperature control switch is directly connected in series to the electrical equipment to control the electrical equipment, So how to use the s
