Classification of electric iron

Electric iron is a tool for ironing wrinkled clothes and cloth with heat. The power is generally between 300-1000W. Its types can be divided into: ordinary type, temperature adjustment type, steam spray type, etc. The iron is simple in structure, cheap in price, and easy to manufacture and maintain. The temperature-adjustable electric iron can automatically adjust the temperature in the range of 60-250°C and can automatically cut off the power. It can be ironed at a suitable temperature according to different clothing, which is better than the ordinary type. Electricity saving; the steam spray type electric iron not only has the function of temperature adjustment, but also generates steam, and some are also equipped with a spray device, which avoids the trouble of manual water spray, and the medical wetting is more uniform and the ironing effect is better. Next, the editor of Xianji.com will explain the classification, working principle, usage skills, attention to use, cleaning methods, selection techniques and maintenance methods of the iron.
Classification of electric iron

1. Ordinary type

The most basic form of the electric iron has a simple structure and is mainly composed of a bottom plate, an electric heating element, a pressing plate, a cover, a handle and the like. Since it cannot adjust the temperature, it has gradually been eliminated.

2. Temperature regulation type

The temperature control device is added to the ordinary electric iron. The temperature control element adopts a bimetallic sheet. The temperature adjustment knob is used to change the initial distance and pressure between the static and moving contacts on the bimetallic sheet to obtain the desired ironing. Temperature, temperature adjustment range is generally 60 ~ 250 ℃.

3. Steam type

The steam generator and the steam controller are added on the basis of the temperature-adjustable electric iron, which has the dual functions of temperature adjustment and steam injection, without manual water spray.

Working principle of electric iron

The temperature of the tool converted from electrical energy to heat is determined by its own power and the length of the energizing time. The large wattage is long and the energizing time is long. The temperature rises quickly and the temperature is high. Conversely, the temperature is slow and the temperature is low. The heating element of the iron has There are two types of mica skeleton heating elements and metal tube heating elements. The electric iron made of mica skeleton heating elements has simple structure, easy manufacturing, relatively uniform heating, and convenient maintenance. The disadvantage is that the heating wire is exposed to the air and oxidizes quickly at high temperatures. , Short life, easily affected by humid air, poor insulation performance, electric iron made of metal tube electric heating element has good mechanical strength, long life, high thermal efficiency, good moisture resistance, safety and reliability, but the manufacturing process is more complicated.
