What You Should Know About Washing Machine Safety From Purchase To Use

Washing machines are popular in more and more families, but more and more accidents are caused by washing machines. In recent years, there have been reports of washing machine wounding incidents, with minor injuries to fingers and serious injuries taking people's lives. In addition, fires, electric shocks, and water leaks caused by washing machines are not uncommon. How to prevent these security incidents from happening? In addition to improving product quality by manufacturers and strengthening supervision by relevant government departments, consumers can effectively prevent safety accidents by knowing some safety common sense when choosing and using washing machines.

1. Protection for washing machine touching live parts

The structural enclosure of the washing machine should be such that exposed live parts should not be accessible by the user. Openings in the washing machine should also not allow fingers to reach internal wiring. This regulation involves the tightness of the product and the planning of the circuit. A qualified electrical product should not only have a scientific circuit design, but also have professional wiring specifications and insulation measures. Thereby, the operation area and the work area of the electrical products are isolated to protect personal safety.

2. Leakage current at the operating temperature of the washing machine

The leakage current between live parts on the inner casing of the washing machine should not exceed 3.5 mA at operating temperature. The safe voltage that the human body can withstand is 36V, the safe current is 10 mA, and the current that can be felt by people is 1 mA. Therefore, the 3.5 mA stipulated by the state is within the safe range, but also within the range of human perception. If there is an electric shock sense, find the cause of the leakage as soon as possible to protect your own safety.

3. Input power of washing machine

At rated voltage and normal temperature, the actual input power of the clothes washer brands should not exceed 15% of its rated power. The output power of the washing machine directly affects the power consumption, so almost all washing machines at present have added the frequency conversion function to effectively improve the utilization rate, allocate the motor frequency on demand, and save power.

4. Washing machine temperature rise

When the washing machine is working normally, the temperature rise of its motor winding should not exceed 75 degrees, and the temperature rise of the outer casing should not exceed 60 degrees. The motor rotates under the electromagnetic drive. In the operation of the motor, the temperature generated by the motor mainly comes from two points, one is the frictional heat generation, and the other is the heat generated by the coil current. If the temperature is too high, it will affect the life of the motor, and even affect the normal use of electrical products.

5. Stability of washing machine

The clothes washer brands should have sufficient stability, and the washing machine should not tip over when placed on an inclined plane 10 degrees from the horizontal in any position during use.

6. The washing machine automatically shuts down

When the washing machine is dehydrating, when the user opens the upper cover by 50 mm, the dehydration motor should be powered off.
