Home appliance manufacturers have their own standards. According to the regulations of the relevant state departments, except for special ones (such as inductive direct fluorescent lamps), the inductive electrical equipment should be above 0.8. The stress rate of resistive electrical equipment is 1.0.
Different electrical appliances have different power factors. However, in general, high-power electrical appliances will pay attention to power factor control when designing, so that the power factor can reach a larger value (for example, above 0.8). In addition, the power factor of the same electrical appliance is different under different working conditions, for example, the power factor is lower when the washing machine is spin-dried, and higher when there are more clothes inside (the power factor is higher when the motor is rated).

Matters needing attention in the use of household appliances:
1, TV is most afraid of being turned on and off without restraint. Every time the machine is turned on, the filament of the picture tube should be preheated to accelerate aging.
2. TV is most afraid of strong magnetic interference. If you move a magnetic object in front of the screen, it will lead to color disorder.
3. The washing machine is most afraid of splashing boiling water. Because boiling water is easy to cause deformation of plastic boxes or plastic parts, the impeller shaft is poorly sealed.
4. When in use, the laundry amount at a time cannot exceed the specified amount of the washing machine. Take coins and sundries out of your pocket before washing. For clothes with metal buttons, fasten the metal buttons and turn the clothes over so that the metal buttons are not exposed, so as to prevent hard objects such as metal from damaging the washing tub and pulsator during washing.
