Why does the electric blanket get hotter and hotter the more you use it? Getting hotter and hotter e

It is estimated that it is the problem of the ambient temperature, not the problem of your electric blanket.

1. The component is damaged

If you encounter this kind of problem, you should first check whether the power cord is good, ensure that the plug and the power socket are in good contact, and the power switch has been turned on.

If there is no problem with the above, it is necessary to check whether the heating element is damaged, you can use the universal meter to check the end point of the power switch connected to the heating element, if the resistance value is , it means that the components in it are damaged.

2. The luminous lamp is damaged

If you open the electric blanket switch button and find that the electric blanket can heat normally, but the indicator light is not on, then it is often the step-down resistance of the light-emitting diode that is damaged.

3. The heating wire is broken

Then check the indicator light of the electric blanket, people who understand physics know that the heating wire and the indicator light of the electric blanket are a parallel circuit, when you connect the electric blanket to the power supply, the current passes through the indicator light and the heating wire of the electric blanket respectively, if only the indicator light is on, it means that the heating wire of your electric blanket is broken, and the circuit cannot be formed, and the electric blanket cannot be heated.

How to choose an electric blanket.

1. Choose according to the specific actual function.

According to whether you need a single or double person, the power of the electric blanket and the budget to buy an electric blanket** to choose, if you want to have a strong sense of experience, you can choose an electric blanket with automatic temperature control, and then ask the store according to your own needs, and learn to distinguish between the truth and the falsehood of the sales staff when the store recommends the electric blanket to us, and you can't decide casually.

2. Look at the label of the electric blanket.

After carefully reading the electric blanket, remember to see if the electric blanket manufacturer, certificate and anti-counterfeiting label are available, and the electric blanket of the big brand should be checked to see if it is a counterfeit and shoddy product, if it is a miscellaneous brand, there will be problems in quality.

The electric blanket not heating may be due to damaged components, damaged lights, or broken electricity.

1. If you encounter this problem, you should first check whether the power cord is in good condition, make sure that the plug and the power socket are in good contact, and the power switch has been turned on. If none of the above is a problem, then the component is broken.

Workaround: Just replace one part and it will continue to work.

2. The light-emitting diode is damaged. If you turn on the switch button of the electric blanket and find that the electric blanket is heating normally, but the indicator light is not on, the step-down resistor of the light-emitting diode is often damaged.

Solution: Replace the light-emitting diode with the same specification. Pay attention to series or parallel connection to determine the resistance value and avoid failure again.

3. The heating wire is brokenWhen the electric blanket is connected to the power supply, the current passes through the indicator light and heating wire of the electric blanket.

Solution: Open the blanket and replace it with a new resistance wire.

This is a temperature-regulating electric blanket, which is generally equipped with two types of temperature control elements: one is an overheating safety thermostat, which requires about 8 9 electric blankets per bed, which are connected in series on the electric heating elements to play a role in safety protection; The other type is the thermostat controller, which is located at the head of the bed or at hand and plays the role of regulating the temperature.

Just adjust the thermostat.

It should be a current issue.

The electric blanket is heated by the resistance wire after it is energized, and if it goes through the process of folding and heavy pressure, the resistance wire is likely to break, so that the current is not passed, and of course it cannot be heated. It is recommended to use an electricity meter to measure whether the resistance wire is well connected, if it is well connected, it is a problem with the power switch.

The electric blanket will produce high temperatures, and a large amount of water in the body will evaporate, making the already dry ** in winter even drier, and the mouth will be dry. You can make some chrysanthemum tea to drink, drink more water, eat more fruits, such as pears and the like A good way to prevent it is to turn on the heat before entering the quilt, turn off the power after entering the quilt, and then strengthen physical exercise and enhance physical fitness to reduce the dependence on electric blankets.

The electric blanket indicator indicates that the electric blanket has been plugged into the 220V power supply, and does not mean that the circuit after the electric blanket is switched on and off is not faulty.

Check whether the electric blanket connection and heating wire are broken.

The diagram below shows a typical temperature-regulated electric blanket circuit. As you can see from the figure, the electric blanket is composed of a temperature control switch, an electric blanket resistance wire (electric heating wire), and a connection between the switch and the heating wire. When the connection or heating wire is broken at any point (shown by the red x in the circuit), the electric blanket will not have current passing through it, and it is impossible to generate heat.

However, none of these breakpoints will affect the illumination of the power indicator, and the current shown in pink will still flow through the indicator unless the power supply is disconnected.

1. It means that the electric blanket has been plugged into the 220V power supply, which does not mean that the circuit after the electric blanket switch is not faulty. Check whether the electric blanket connection and heating wire are broken.

2. It may be that the power is not turned on. Some electric blanket controllers have a power switch on the panel, instead of a temperature control switch, check whether it is turned on. It may also be that the connection between the controller and the hair ** is not in good contact.

3. It may be a fuse protection. If you have been using it and there is no problem with the power supply, plugging in the blanket, and the turning on status indicator does not light up, it means that the fuse is protected, do not replace it by yourself, because the line is protected, it means that there is a short circuit somewhere.

Precautions for the use of electric blankets:

1. The electric blanket should not be in direct contact with **.

The heating parts of the electric blanket are metal tubes, these metal tubes can easily lead to uneven heating if they are in direct contact with the human body, so that the local temperature of the human body increases, and if the electric blanket is turned on overnight, it may increase the chance of burns, so it is best to spread a blanket on top of the electric blanket.

2. The electric blanket cannot be folded repeatedly.

If the electric blanket is folded repeatedly, the heating wire will be broken, resulting in excessive local resistance, which is easy to induce fire and the risk of blanket leakage.

3. In addition, for some special patients, pregnant women, children and other people, it is not advisable to use electric blankets, so as not to affect their health.

(1) The power cord plug of the electric blanket is not in good contact with the power socket.

Replace the plug or socket.

2) If the power switch of the electric blanket is not touched well, modify the moving contact of the power switch.

When the moving contact is damaged, replace the moving contact.

3) The static contact of the power switch is desoldered from the solder joint of the power line.

Open the power switch case and solder the power cord from scratch with an electric soldering iron.

4) Open circuit of electric heating element.

At the two ends of the electric heating element connected in the power switch, the resistance value of the electric heating element is detected with a multimeter ohm, and when the pointer is " ", it indicates that the electric heating element has been disconnected, and the electric heating element is replaced.

Replace the plug or socket.

At the two ends of the electric heating element connected in the power switch, the resistance value of the electric heating element is detected with a multimeter ohm, and when the pointer is " ", it indicates that the electric heating element has been disconnected, and the electric heating element is replaced.

When the power supply of the electric blanket is turned on, the current passes through the indicator light of the electric blanket and the electric blanket respectively, if only the indicator light is on, it means that the heating wire of the electric blanket is burned out and cannot form a circuit of the circuit. The electric blanket is pressed under the bed for a long time and is damp, which will also affect the normal circuit of the current and will not generate heat.

Another is not the right way you laid the groundwork.

Bedding method: from top to bottom, bedding, sheets, thin blankets, >electric blankets, cotton wool, mattresses. There is also the need to drain moisture for the first time! Moisture discharge method: Turn on the electric blanket to the heating mode, spread the futon for two hours, and lift the futon to dissipate the moisture to restore the heat effect.

I bought a new sheep dual-control electric blanket (70 yuan) in the supermarket, what is written on the double helix thickening or something, after I went home, I opened the high temperature for an hour according to the instructions, but it is not very hot, I remember that the little sheep electric blanket I used to use was very hot at high temperature for a while, is there a problem with my newly bought electric blanket?

If there is no temperature blessing of the electric blanket in the cold winter, it is too cold at night, it is difficult to sleep, for newcomers who have just used the electric blanket, they are not clear about a lot of knowledge about the electric blanket, let me explain to you, such as how long can the electric blanket be hot? Why is the high temperature of the electric blanket not too hot?

The electric blanket can be heated in about 20 minutes. According to the brand and power of the electric blanket, the speed of heat will also be different, generally in twenty minutes, but some electric blankets heat faster, a few minutes can be, some electric blankets are relatively slow, it takes half an hour, so you can power on the electric blanket half an hour before going to bed, the temperature setting should not be too high, the medium range can be, and adjust to low gear after sleeping.

The electric heat is not very hot, and it may be that the electric blanket is damaged. The weather in the south is humid, and if you accidentally spill water on the electric blanket, it will cause this situation, so you need to pay attention to this when using the electric blanket, and try to keep the water source away from the electric blanket.

The electric blanket can not touch the water, so when cleaning the electric blanket in the mu, you can choose to use a brush to clean the limbs, and then put it in a ventilated place to dry, do not put the electric blanket in a dark and damp place, nor can you use electricity to dry, do not often use the electric blanket when it is hot, do not fold the electric blanket, roll it into a cylinder and store it so that it will not be hot after powering.
