Electric blankets, also known as electric mattresses, are contact electric heaters. It will be specially manufactured, and the insulating performance reaches a standard soft cable -type electric heating element in a disk or sewed into the blanket.The working principle and structure are similar to the electric blanket, as well as warm blankets, electric mattresses and electric pads.
What are the types of electric blankets
Without signal line type
For ordinary electric blankets.The electric heating alloys used are straight, but they are more spiral -shaped wrapped in the heat -resistant core, and a layer of heat -resistant resin is coated outside.
Signal line
Used for temperature -tone electric blankets.The core is compiled with glass fiber or polyester, with a flexible electrical alloy wire (or foil belt) wrapped on it.The line is around the sensing layer and coats a layer of heat -resistant resin at the outermost layer.When the temperature at any point on the electric blanket exceeds the predetermined value, the sensing layer on the corresponding electric heating wire is changed from the insulator to a good conductor, which makes the control circuit connect.Purpose.
Using ordinary electric blankets without signal wire -type electric heating elements, if you want to achieve temperature control, there are generally two types of temperature control components: one is an overheated safety heximal insulation, which takes about 8-9 electric blankets per bed.On the electric heating element, it plays a safe protection effect; the other is the constant thermostat controller, which is set on the bed or hand to regulate the temperature of the temperature.Electric blankets with signal wires only require a constant temperature controller.
Introduction to electric blanket purchase tips
In modern life, the fire is basically gone. How can you enjoy the happiness of the fire? Electric blankets! Many people think of it.Indeed, sleeping in the electric blanket in winter is like sleeping on the hot hoe.Electric blankets are already necessary for winter supplies in some areas with unsatisfactory heating.So how to buy electric blankets, lets take a look at the electric blanket to buy tips.
1. Look at the logo. This is the prerequisite for purchasing electric blankets, and also the safety guarantee of using electric blankets.Electric blankets must be a product that is qualified by relevant departments or units, and must have a qualified certificate and an online checked production license number.
2. Look at the power and use it on demand, both energy saving and good health.The power of the electric blanket is not bigger, the better, it is best to determine it according to the number of people. Single people should not exceed 60W, and double people should not exceed 120W.
3. Relying on the quality, the quality.The quality of the electric blanket is flat and soft, and the fabric has no leakage needle. The internal electricity heating line should be arranged for neat rules. There is no overlap and knotting.
4. Look at the appearance.The power controller should be complete, smooth, and non -defective. It is flexible and has a clear switch mark.
5. Select intelligent energy -saving models.Select automatically controlled, save power, save trouble, safe and reliable.
6. Test before election.When powering, the sound of rustling should not be made in the mattress; after a few minutes, the hand touching the electric blanket should feel calories.
