What should we pay attention to when the weather is wet?

Instructions for the use of electrical appliances in wet weather

It's best to turn on the dehumidifier to extract indoor moisture and keep the appliances dry.

Avoid placing TV sets and audio-visual equipment in damp places.

Avoid putting water containers such as vases or cups on TV sets or audio-visual equipment.

Wait at least 3 seconds after starting up before turning off, and wait 3 seconds after turning off before turning on.

If abnormal phenomena are found in TV sets and audio-visual equipment, stop using them immediately and hire qualified personnel for maintenance.

Humidity is easy to cause electrical short circuit.

When the weather is wet, the probability of electrical short circuit is greatly increased. If the TV is turned on continuously, it will also be short-circuited due to the impact of tens of millions of currents.

Experts say that wet weather can easily lead to electrical problems, and humidity will increase the probability of electrical short circuit. The situation is like pouring a cup of boiling water on an electrical appliance, and there is a possibility of short circuit immediately.

In addition, if the TV switch is too frequent, there will be a chance of electric shock, and overload will burn out the circuit and smoke. If a serious short circuit is caused, there will be a chance of explosion.

Even in dry weather, people should not turn on and off the TV too often. They should wait at least 3 seconds after turning on the computer and at least 3 seconds after turning off the computer. In wet weather, they should turn on the dehumidifier to reduce the indoor humidity.

During this time, the wet and cloudy weather made the general public feel very uncomfortable. This kind of weather is not only bad for health, but also has hidden dangers for home appliances. A few days ago, a friend of the reporter complained to the reporter that the computer monitor at home automatically went black in less than three minutes. Later, I checked it. It turned out that the weather was wet and the picture tube was wet. Yao Wenzhen, president of Guangzhou Electrical Appliance Maintenance Industry Association, said that in wet days, household appliances such as color TV sets, refrigerators, washing machines and DVD players are very susceptible to moisture. President Yao specially reminded that digital cameras, digital video cameras and other products should not be put in leather cases for a long time, but should be put in a drying box with silica gel to prevent moisture. Then, how do large household appliances such as color TVs and air conditioners prevent moisture? Please see the following introduction one by one.

1, color TV is moistureproof

First of all, we should pay attention to the maintenance of color TV and put it in a ventilated position.

Secondly, when the weather is wet, the color TV can enter the standby state. Because the internal transformer and other working parts will heat up during standby, the water in the body can be emitted in this way.

In addition, there are many small holes in the back shell of color TV, and dust will enter the TV through these holes after a long time. When the weather is wet, condensation will condense with dust, which will lead to "leakage" of TV. Therefore, users can use the hair dryer to move the hair dryer up and down, left and right through the small hole on the back of the TV to "expel" the dust and moisture inside the TV.

Finally, for color TVs that have been used for a certain number of years, you can ask professional maintenance personnel to come to the door for maintenance and clean up the internal dust.

The washing machine is moisture-proof.

Many citizens will think that the washing machine itself is dealing with water, and there is no need to prevent moisture. In fact, this view is wrong, especially for circuit-controlled washing machines. According to relevant experts, it is best for qualified users not to place the washing machine in places with high water vapor density such as toilets. In addition, the washing machine can also be placed on a raised platform. In addition, the electric control components should be protected from water, and should be stopped immediately when there is a fault, waiting for professional maintenance personnel to come to the door for maintenance.

3, air conditioning moistureproof

Although the air conditioner has the function of dehumidification, it also needs to be maintained when wet days come to prevent dampness. Due to the obvious temperature difference between outdoor temperature and indoor temperature, water dew and dust will be produced in the air conditioning pipeline, which will have an impact on human health if it is used for a long time. If the air conditioner is not used for a long time, the product parts will age and the plastic material will become hard. After three or four months in winter, turn on the air conditioner irregularly to ensure that the air conditioner is in good condition.

4, computer moistureproof

Computers especially need moisture protection, because excessive humidity will short-circuit the internal circuit of the computer, thus causing machine failure.

Moreover, when the weather is wet, if the computer is not properly grounded, it is easy to cause the fuselage to be charged.

Therefore, you can turn on the computer for at least one hour every day to dissipate the moisture in the computer case through the heat generated during the operation of the computer. When the weather is too humid, two packages of desiccant can be placed in the computer case, and the case and monitor can be covered with dust-proof and moisture-proof cloth.
