I always listen to people saying that "electric appliances are not afraid of being used badly, they are afraid of letting go." I still don't believe it at the beginning. How come? As a result, I went back to my hometown some time ago and found that the notebook that I lost at home couldn’t open the machine... I couldn’t open the machine... I couldn’t open the machine.../(ㄒoㄒ)/~~ However, it’s not the worst, only worse, when washing clothes, it’s quick to wash. Well, suddenly the washing machine is not powered. Calling the repairman, it is possible that the motor is not working... Scorpio, I am letting it go! I haven’t been convinced that I haven’t been home for so many months! ! !
In order to prevent the cup from happening again, the baby I seriously studied what kind of appliances would be bad if they were not used. The electrical appliances mentioned here refer to all electrical appliances, mobile phones, notebooks and other electronic products.
Then let me talk about why the appliance is not going to be bad.
Xiaobian compiled a variety of information, summed up the reasons for the destruction of electrical appliances can be as follows:
1. Insects, ants, and spiders can enter the interior, causing damage to the board, causing a short circuit to damage the appliance.
2. Dust. The electrical equipment has not been used for a long time, and the environment of the circuit board has changed. The accumulated dust will absorb the moisture in the air, corrode the pins of the circuit board and small parts (the lead wire on the chip), and accelerate the aging. Therefore, regular use is the best way to avoid damage.
3. Electrolytic capacitors. Long-term non-charge and discharge may have some impact on the capacity, and the non-energized life of the capacitor is much shorter than the energization life. Almost all appliances with intelligent circuit control have their appearance, such as TV, telephone, air conditioner, tape recorder, mobile phone, computer and so on.
4. The main reason why electrical appliances do not need to be damaged for a long time is tide. Any type of electrical appliance is most afraid of moisture. It will not only cause partial rusting of metal parts, but also electronic components, circuit boards, etc. in electrical appliances are corroded. When the appliance is used, it will be hot and can drive away the moisture.
Then the problem is coming again, so which appliances will be bad if they are not in use?
Refrigerator
In terms of the performance of the refrigerator, it is best to use it all the year round, and do not stop when it changes due to the season. Because the temperature inside the box is the same as the surrounding ambient temperature after the refrigerator is deactivated, and the temperature inside the box is quite different from that in normal operation, the long-term cold and heat will accelerate the aging of the plastic parts inside the box, and the premature crack damage . In addition, when the refrigerator is not working, the acid (alkali) trace substance remaining on the surface of the evaporator at normal temperature is liable to corrode the evaporator, which may cause the evaporator to be perforated and damaged.
2. Hard disk
Hard disk damage is generally caused by moisture and line oxidation. Moisture will gradually erode the metal parts of the board, such as pins and connectors, and the resulting rust will increase the resistance, causing poor contact to affect the normal transmission of the circuit. At the same time, the small moisture accumulated on the circuit board circuit may also cause a partial short circuit, and the pins and gold fingers of the interface portion of the hard disk are oxidized by oxygen to form a dark oxide layer, which increases the impedance and causes poor contact.
Mobile phone
Turning off the phone for a long time will not be bad, but the battery is hard to say. Because although the phone is turned off, the battery is still powering the phone to ensure that the phone's real-time clock works properly. Although this power consumption is small, too long a time will cause the battery to be over-discharged and need to be activated when it is used again.
4. Inkjet printer
Inkjet printers will not break for a long time. When the nozzle of the ink cartridge is exposed to the air for a long time or in an outdoor environment, the evaporation of the ink cartridge is accelerated, which directly affects the storage time of the ink cartridge. And the bad environment can also cause the nozzle to be blocked.
