Which appliances need to be unplugged when they are not needed?

Before you go out, you may remember to turn off the water, turn off the lights, turn off the air conditioning, turn off the **, but there is one thing you probably won't do — unplug the appliance. You may think that shutting down the power supply is safe, but in reality it is not the case. As long as the plug is not plugged in, the appliance is in standby mode, and it is still quietly consuming electricity. As a result, the electricity cost of a family for more than one year may even be as high as several hundred thousand yuan. ! Not only that, there is still a hidden danger of not pulling the plug, which may cause fire. Therefore, when not using electrical appliances, it is better to unplug the plug and completely power off.

Is it true that all household appliances need to be unplugged?

Electric remote control is still charged

When asked about the disadvantages of appliances without plugs, many people still know that they will waste electricity, but most people do not agree with this. Even small series will not unplug electric plugs, such as televisions, air conditioners, set-top boxes, etc., all of which are directly controlled by the remote control. (It would be too much trouble to pull the plug every time. Of course, there are many people who do not care about money.)

Many people think that it's fine to turn off the appliance with a remote control. In fact, they are still in the standby state, that is, live state. In other words, electrical appliances consume power in standby mode, and some appliances consume a lot of power. "Besides, in the fire caused by electrical appliances, there are many cases of electrical appliances waiting for ignition, especially air conditioning.

Xiao Bian will simply help you count: For example, if the air conditioner is not used, but the outlet is still not powered, if the standby power is 1.11 watts, even if it is not used throughout the year, it will consume 9.7236 kWh. 0.5 yuan calculation, a year wasted 4.8 yuan; if the washing machine standby power at 2 watts, even if not used throughout the year, it will consume 17.5 degrees, with an average of 0.5 yuan per kilowatt-hour calculation, a year to waste 8.8 yuan; The standby power of the computer host is 4.8 watts. Even if it is not used for the whole year, it will consume 42 degrees. Calculating at an average cost of 0.5 yuan per kWh, it will waste 21 yuan a year.

Although the power consumption of each appliance in the home does not seem to have much power for one year, when the cost of all the appliances in the home is added up, the number for one year is quite terrible. If the Shanghai resident population is estimated at about 4.5 million, this year's costs are staggering.

Most Power Consumption in Standby State: Set Top Box

How much electricity is consumed in the standby mode for common electrical appliances such as TVs, air conditioners, and laptops? In fact, you can buy a power display socket yourself. The power of the set-top box was detected to be 15.4W. After turning off the set-top box, the power is 15.2W. It can be seen that the set-top box is definitely a master of stealing electricity.

Do not underestimate the set-top box, standby power consumption is very alarming, especially now a lot of set-top boxes are false standby, if you open the remote control, immediately enter the TV screen without delay, then this is mostly false standby, small series After accounting for an account, such a false standby state consumes more than 100 kWh of electricity a year, and costs an additional 50 yuan in electricity.

Most electrical appliances consume electricity without knowing it. I don't see much standby power, but if I multiply it by 24 hours and multiply it by 365 days, I believe the data will be very amazing. In addition, taking a computer host as an example, if a power-saving outlet is not used, even if the computer is not used for 365 days a year, as long as the plug is not unplugged, the entire year will still consume 42 degrees.

Do not pull the power who is most dangerous: air conditioning, drinking fountains

At present, the quality of outlets, patch panels, and connection lines on the market is quite different. If the appliance is not used for a long time and it is not unplugged, it can easily cause a fire. According to experts, although some appliances have automatic stop function, as long as the power switch is not turned off, the power part of the machine is in working condition and emits heat. When the ventilation is poor and heat accumulates to a certain extent, it may burn the insulation layer to form a short circuit. Fire caused.

Among household appliances, air conditioners and drinking fountains are the most dangerous when they are not plugged. The power of air conditioners is high, especially in the absence of people in the home, and it is very easy to have a fire. “The hidden dangers of water dispensers are less likely to attract everyone’s attention. Its structure is relatively simple. At the top is to use a 'smart seat' to seal the water. Once this “smart seat” leaks and the plug is not pulled, it may cause fire. Experts explained this way.

Which appliances must be unplugged in the end

Of course, some electrical appliances with a power switch will not have to be unplugged after power off, and almost no power consumption, such as blowing wind, fans, ovens, etc... also include televisions (not just turning off the remote control, it is Turn off the onboard power switch)

However, all appliances with remote controls, such as air conditioners, Blu-ray players, stereos, set-top boxes, etc., are remotely powered off and the remote receiving part is still working, waiting for you to use the next operation of the remote controller at any time. The remote control receiving part has little power, but the standby time will be very long, and power consumption cannot be ignored.

So, if a troubled friend can also replace the socket with a controllable socket, in order to turn off the power at any time. Going out on the go can save you unnecessary costs. Why not? (Small series really is not selling outlets!) Of course, thunderstorms must remember to pull out the plug to prevent electrical and personal injury caused by the invasion of lightning with the signal line.
