Do household appliances need to be unplugged when they are not in use? Will it cost electricity if y

You don't need to unplug the home appliances when you don't use them, if you want to say that there is no consumption at all, it will definitely not, there will be a little bit, but this consumption is almost negligible. Because all the household appliances in the house are plugged in when they are not running, the energy consumption it produces is very weak, and it is not as good as lighting the light bulb at home. <>

Now the light bulbs in the house are energy-saving lamps.

20 watts is already very bright, the energy consumption in this area is very little, because a day has to be 10 hours, 5 days in a row to consume one kilowatt-hour of electricity, a month only consumes 6 kilowatt-hours of electricity, three dollars can meet your one-month proof needs, very few families light up, need to be connected to the point for 10 hours, the day is not at home, the time at home at night is also limited, all kinds of household appliances themselves are only on electricity when they are not operating, and the consumption it produces will be a little bit. But this little bit is that all the household appliances at home together are not as good as this bulb for an hour, and it is noted that all the household appliances together are silently consumed for a month. <>

The concept of the older generation is sometimes wrong, including some people think that the refrigerator at home has been cooled, so it is better to unplug it and plug it in when it is almost dissolved. In this way, the refrigerator works for a short time, won't it save electricity? Let's not talk about the damage to the refrigerator itself, which will greatly shorten the service life of the refrigerator, let's talk about the impact on refrigeration power consumption.

When the temperature inside reaches a certain standard, the refrigerator will not be refrigerated all the timeWhen the energy consumption is not cooling, it is very small, but if it is almost melted, the refrigerator will enter a strong cold state, and it will consume a lot more energy. <>

The usual electricity consumption at home is relatively large, and the electricity bill is more than 100 yuan per month, in addition to the special situation of the heater used by the air conditioner in winter and summer, there is such a high consumption, that is, the electrical appliances at home are used too much, and the number is too large to a certain extent, for example, the electric wok, which is basically 3 kilowatts, and regular use will naturally consume electricity, which is unavoidable. But when ordinary electrical appliances are plugged into the socket, there is really no consumption, and there is no need to waste this time and energy to unplug it again.

There is no need to unplug it at all,My professional electronic R&D engineer,Design circuits every day,The power consumption of electrical appliances in standby state is reduced to more than 1/100,000 of the original,Take TV as an example, it only consumes one kilowatt-hour of power in the standby state for ten years,Is it necessary to unplug the socket? We should believe in science and not be blind and diligent.

It must be needed, otherwise it is easy to cause a fire, in recent years, a lot of news is caused by a fire caused by not pulling out the bolt, and secondly, if you don't pull it out, it will definitely cost electricity, because it has been used!

I think it needs to be unplugged, otherwise there will be certain safety hazards, and it will definitely cost electricity if you don't pull it out.

Plugging is power-hungry.

Just turn off the power of the appliances and do not unplug the power plugs, the power supply part of these appliances is still working, this state is also known as the standby state, although the power consumption is not much, but the power consumption accumulated for a long time is not small! Those high-power household appliances with remote control switches, such as air conditioners and televisions, are still in standby mode after they are turned off, and they are still charging to receive signals.

In particular, after some TVs are turned off, the CRT is still in the state of filament preheating and standby, and in the standby state, there are still watts of power consumption. This type of appliance does not unplug for a long time, not only does it consume electricity, but it is also prone to fire.

In addition to this, here are a few things to keep in mind:

1. Don't just turn off the remote control switch. Like TVs, set-top boxes, automatic washing machines, etc., be sure to turn off the mechanical switches.

2. There is no mechanical switch for the air conditioner, plugging in the plug is standby, it will consume electricity, and it is best to unplug the power supply when not in use. The air conditioner with remote control function has a standby power consumption of about 8 watts, and the power should be cut off when the air conditioner is not used for a long time.

3. Although the power consumption of the computer in the sleep state is less than half of that after it is turned on, there will still be watts of energy consumption. Therefore, the best way to reduce the energy consumption of computers and monitors is to unplug them without turning them off in time.

Be. Because the power of the household appliance is turned off after use, but the plug is still plugged in the socket, and the inside is still energized, which is equivalent to a standby state. In the standby state, if the motor components inside the electrical appliance have a short-circuit fault, and the leakage switch at home does not act in time, then the result is to burn the electrical appliance and seriously cause the circuit.

And when the electrical appliance is in standby, that is, in the live state, that is to say, the electrical appliance will consume electricity in the standby state, and the power consumption of some electrical appliances is quite amazing.

General household appliances, such as computers, TVs, microwave ovens, induction cookers, electric water heaters, rice cookers, electric pressure cookers, water dispensers, TV set-top boxes, range hoods, automatic washing machines, routers, air conditioners, etc., are standby power consumption. Because the appliance plug is still connected to the socket, the internal circuit board is still in working condition, so it consumes power.

So, how much power will it consume?

The most power-consuming TV set-top box,The measured normal starting power is,Standby power is,It's about the same as daily use! Based on the power consumption of 15 watts per hour, the power consumption of a set-top box in a month has reached the degree.

Let's look at other appliances:

standby power of gas water heater; Air conditioner standby power; range hood standby power; rice cooker standby power; Front-loading washing machine standby power.

Surveys have shown that the standby power consumption of households in some cities in China has accounted for about 10% of the total electricity consumption of households.

Second, not pulling the plug not only consumes electricity, but also has potential safety hazards.

Many appliances that do not unplug for a long time are not only as simple as consuming electricity, but also have safety risks.

1) Electrical appliances in the long-term energized state, under overload work, will cause the aging of electrical appliances and the accelerated aging of the circuit. In order to avoid the unsafe factors caused by aging, it is not recommended that household appliances be in standby mode for a long time.

2) If the electrical appliance is in a long-term power-on state, it may cause the socket to heat up, or even smoke**, and there will be vicious accidents such as leakage and fire.

3) During the thunderstorm season, once lightning invades the power supply line, household appliances in standby mode may be damaged or even cause fire.

In addition, even if the mobile phone charger is not unplugged, there is still power consumption. If the charger is not unplugged for a long time, overheating of the power supply device for a long time can cause damage or cause a fire. And the long-term charging of the mobile phone will also affect the life of the electric board, many of the news of mobile phone charging, many of them are caused by the long-term charging time is too long, and we must pay attention to it.

Does an appliance consume electricity if it is not unplugged? In particular, these 3 types consume a lot of electricity in a year.

After using the TV, washing machine, air conditioner and other electricity, press the power off button casually, and do not pull the plug. These power supplies are not unplugged, and over time, a lot of electricity will be wasted.

High-power household appliances with remote control switches, such as air conditioners, water dispensers, vacuum cleaners, etc., are still in standby state after being turned off, and are still charging and receiving signals. In particular, after some TVs are turned off, the CRT is still in the state of filament preheating and standby, and in the standby state, it still has wattage power consumption.

Yes, but when it is not in use, it is a standby power, which is very small.

Electricity. For example, air conditioners are generally turned on in the summer when it feels very hot or when it is so cold that you cry in the winter, and they are not used at other times. If you don't pull the plug when the air conditioner is not in use, it will cause waste.

Moreover, the air conditioner is a high-power electrical appliance, which is very prone to phenomena such as **, and if you don't pay attention, there will be potential safety hazards.
