Generally, the electrical appliances that directly use 220 V alternating current and are larger than 1200W are called high-power electrical appliances, so as to distinguish the electrical appliances whose step-down mains electricity is converted into DC, and the washing machine belongs to the range of high-power electrical appliances.

Extended data

1, most students' safety management regulations indicate that heating is fast, and the power of electric stoves, electric cookers, rice cookers, electric heaters, electric blankets, electric cups, curling irons and hair dryers exceeds 1000W, and electric irons, induction cookers and microwave ovens are all high-powered and are prohibited.

2. The standard of high-power electrical appliances in dormitory is different in different schools. General high-power TV mainly refers to electric cookers, electric cups, induction cookers, rapid heating and so on. Generally, the electricity consumption in dormitories is limited to about 450 watts, and those exceeding these watts become high-power appliances.

3. The allowable temperature of wire insulation is generally 60℃. If it is fully loaded and overloaded for a long time, the heating value of the line will increase and the insulation layer will accelerate aging. When the temperature is higher than 250℃, the insulating layer will spontaneously ignite, resulting in short circuit and fire accident. The power of electric appliances such as rice cookers, induction cookers, heaters, hair dryers, etc. is above 500 W. If they are used in dormitories for a long time, it will easily lead to overheating and short circuit of wires, which will lead to fire.
