From the purchase to the use of washing machine safety knowledge you should know
With the popularity of washing machines, more and more people use washing machines to wash clothes, and washing machines cause more and more accidents. In recent years, there have been reports of injuries to washing machines. Light injuries have captured the lives of people with severe finger injuries. In addition, fires, electric shocks, and water leakage caused by washing machines are also commonplace. How to prevent these security accidents from happening? In addition to manufacturers to improve product quality, the relevant government departments to strengthen supervision, consumers in the purchase and use of washing machines to understand some of the common sense of security can effectively prevent the occurrence of security incidents.

1. Protection against touching live parts
The structure of the washing machine should be such that the user should not touch the exposed live parts. The opening of the washing machine should also not allow the finger to reach the internal wiring.
This regulation relates to the product's tightness and circuit planning. A qualified electrical product must not only have a scientific circuit design, but should also have professional wiring specifications and insulation measures. In this way, the operating area and work area of ​​the electrical product are isolated and personal safety is protected.
2. Leakage current at operating temperature
At operating temperatures, leakage currents between live parts on the inside of the washing machine should not exceed 3.5 mA.
The safe voltage that the human body can endure is safe voltage is 36V, safe current is 10 milliamps, and can cause people to feel the electric current is 1 milliamperes. Therefore, the national regulation of 3.5 mA is within the scope of safety, but it is also within the scope of human perception. If there is a sense of electric shock, find the cause of the leakage as soon as possible to protect their own safety.
3, input power
The actual input power of the washing machine should not exceed 15% of its rated power at rated voltage and normal temperature.
The output power of the washing machine directly affects the power consumption. Therefore, almost all the washing machines at present have been added with the frequency conversion function, which effectively improves the utilization rate, allocates the motor frequency on demand, and saves energy.
4, 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 housing should not exceed 60 degrees.
The motor rotates under electromagnetic drive. In the motor work, the temperature generated by the motor mainly comes from two points, one is friction heat, the other is that the coil current generates heat. 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
The washing machine should have sufficient stability. In any position during use, it should be placed on an inclined plane that is 10 degrees from the horizontal plane. The washing machine should not be turned over.
6, automatic power off
In the dehydration operation of the washing machine, when the user opens the upper cover by 50 mm, the dehydration motor should be powered off.

· Risk of electric shock: Do not pull the cord to pull out the power plug; do not use wet hands to plug/unplug it.
For socket industry regulations, it is better to have a wall socket not less than 1.8 meters from the ground; concealed sockets should not be less than 0.3 meters from the ground. The socket for the kitchen and toilet should be 1.5 meters above the ground, and the outlet for air conditioning should be at least 2 meters. There are also some sockets, which lack the necessary protective measures. The splash panel or plastic baffle plate is preferably installed on the socket panel, which can effectively prevent the short circuit caused by oil and water vapor intrusion. For families with children, to prevent children from touching with their fingers or metal objects, use a safety socket with a safety flap.
Sharing a socket with multiple appliances is also a common phenomenon. This will overload the appliance and cause a fire. Air-conditioning, washing machines, range hoods and other high-power appliances are best to use a separate outlet.
Fatal danger: The old machine should handle this way — unplugging and cutting the power cord; breaking the lock on the dryer door to prevent children from trapping themselves inside and causing suffocation to die.
· Risk of suffocation: After opening the new machine, place the outer packaging, plastic film, and foam in places that children cannot touch.
· Danger of poisoning: Please place softener and detergent in a place that is not easily touched by children.
• Explosion hazard: Washing clothing containing solvents is prone to explosion hazards; if there is no special down jacket washing procedure, washing down jackets using washing machines can easily cause explosions.
· Danger of injury: During high temperature washing, the glass of the laundry dryer cabin door will be very hot, and it will be prone to scald; when the machine removes hot water, be careful scald; if the machine is still rotating, do not touch the inner cylinder; when the machine is working, please Make sure that the drain pump cover is tight enough to prevent water leakage or contact with the working parts inside the pump.

â—Thunderstorm weather safety instructions
Professional lightning protection knowledge: 1. Buildings should be protected against direct lightning by lightning protection regulations; 2. Residential power cables, telephone lines, and TV antennas should be shielded and grounded; 3. Household appliances should be maintained with the external walls of the building when installed. A certain distance; Fourth, install household appliances over-voltage protection device on the corresponding line.
For the average family, three arresters should be installed: single-phase power surge arrestors installed at the power supply line to the household power switch; TV feed line lightning arresters installed at the incoming line of the television distributor after the television feeder enters the room; telephone arrester installed in the room after On the telephone line, the telephone is connected to the telephone line through the telephone arrester. The function of these arresters is to shunt and limit the electromagnetic pulses that invade from the line, so as to protect the household appliances.
Expert Tips: Pre-thunderstorm weather, you should unplug the power cord, and broadband network lines, digital TV set-top box signal lines, fixed telephone lines and other network signal lines, is the simplest and most secure way. However, if you hear thunder coming close, don't rush to plug in the wires to avoid electric shock.
In addition, there are people installing solar water heaters on the roof, should pay attention to the lightning protection measures for water heaters. First of all, when installing a solar water heater, the water heater should be placed within the protection scope of the lightning protection device as far as possible. General solar water heaters should be at least 60 centimeters below the lightning protection device and should be kept at a distance of about 1 meter. For satellite receivers such as antennas and small ears, it must be removed when thundering, because they are more likely to be "brought about" by lightning. And when lightning strikes, it is best not to use mobile phones to answer calls.

There are detergent detergents, perfumes, plus brighteners and other ingredients, these chemicals are also harmful to the human body, easily cause skin aging, rough, and even cause skin irritation or rash.
Is soap out of date? The main ingredient of soap is sodium benzoate, which is extracted from animal and vegetable fats. It has many natural ingredients and is not harmful to the human body. Even the soap only removes some of the impurities in the soap, adding a little spice, so the soap is also a relatively natural washing product. In addition, the sewage discharged after washing with soaps has less impact on the environment.
Therefore, it is best to use soap when washing clothes, especially underwear or baby clothes. Wash your hands on weekdays. If it is not stained with special stains that are difficult to wash, you may use soap. When washing dishes or decontamination, wear rubber gloves. Hot water plus alkali with strong decontamination ability can be decontaminated; for softener, if it is not high-grade Cashmere Sweater or silk clothing, ordinary clothing can be thoroughly cleaned by rubbing it with soap.
