Maintenance of electric blankets 4 ways to easily troubleshoot electric blanket failures
1. Maintenance of electric blankets
The maintenance of the electric blanket should pay attention to the following points: ① It is forbidden to fold the electric blanket when it is not in use. When storing, it should be folded gently and placed on top of other items to prevent the resistance wire in the electric blanket from being pressed. ②When cleaning the electric blanket, never wash it with a washing machine, use water and washing powder to gently brush it, do not rub it with your hands, and use it after drying; ③When drying, it should not be exposed to the sun, let alone For drying treatment, it should be placed in a cool and ventilated place and let it dry naturally; ④The electric blanket should not be placed on a sofa or a Simmons bed, but on a hard bed.
Second, the use of electric blankets
The following points should be paid attention to when using electric blankets: ① The power supply voltage should be consistent with the allowable rated voltage of the electric blanket; ② If the electric blanket is stored or used for the first time, the electric blanket should be lightly stacked several layers and energized for 10 minutes for a preheating test, because the folded electric blanket will heat faster. If it is hot, it means that the electric blanket is normal; if it does not, it should be stopped and repaired; ③ The electric blanket should be laid flat under the sheets when in use, and it is forbidden to fold it and use it to avoid accidents caused by overheating; ④ Do not put the pillow when using it. Put it on the electric blanket; ⑤ Children or people who cannot take care of themselves are prohibited from using electric blankets, let alone unqualified electric blankets; ⑥ It should be used according to the high temperature block first and then the heat preservation block.
3. Repair of the electric blanket
①The electric blanket does not heat up after it is powered on: this fault is a common fault of the electric blanket, and you should check whether the power cord is in good condition ; Whether the power plug is in good contact with the power supply; whether the power switch is in good condition; whether the heating element is damaged. Use a multimeter to check the terminal connected to the heating element in the power switch. If the resistance value is ∞, the heating element is broken and the heating element should be replaced.
② Diode temperature adjustment electric blanket temperature adjustment failure: If this fault is manifested in the low temperature block and the temperature is still high, it means that the temperature control diode is broken down; if it is only high temperature block without low temperature block, it means that the The temperature diode is open circuit, the two cases can be eliminated by replacing the diode with the same specification.
③ Capacitor step-down temperature adjustment electric blanket temperature adjustment failure: If this fault shows that the temperature of the high and low gears are the same, it means that the capacitor is short-circuited; Indicates that the capacitor is open circuit, in these two cases, it is necessary to replace the capacitor of the same specification.
④The indicator light of the electric blanket is not on but can heat normally: the cause of the failure may be that the LED or neon bulb is damaged, replace it; (Note: The resistance value of the series or parallel type is very different, so you should pay attention to it when replacing); if the wiring is vacant or full, you can re-weld it.
Safety usage of electric blankets
①When using electric blankets, lay them flat on the pad tire, and add a sheet on the blanket to avoid soiling the electric heater blanket. Never put batting or other fabrics between the sheets and the electric blanket. Switches should be placed within easy reach.
②Turn on the high temperature gear before going to bed, and let it warm up to the required temperature in a short time. After going to bed, adjust to low temperature to keep warm or turn off the switch.
③The temperature of the electric blanket should be controlled at about 38°C, and the maximum temperature should not exceed 40°C.
④ Sharp metal objects and heavy and hard objects should not be placed on the electric blanket. Children should not jump and play on the electric blanket, so as not to damage the heating wire and cause an electric shock accident.
⑤ Always check whether the electric blanket is piled and pleated to avoid local overheating. In order to flatten the electric blanket, the four corners can be sewn with cloth strips, the blanket can be leveled, and then the cloth strips can be fixed to the legs of the bed.
⑥Do not use electric blankets with hot water bottles and soup pots. The partial overheating of the electric blanket is a harbinger of failure. It should be stopped immediately and checked and repaired.
Maintenance method of electric blanket
①Rolling blanket: When the electric blanket is not in use, it should be rolled into a cylindrical shape. Reduce the insulation performance of the heating wire, and avoid placing heavy objects on it.
②Dehumidification: Before storing the electric blanket, spread it out flat, plug in the power supply, and let it cool down naturally after 20-30 minutes of electrification to remove moisture from the heating wire and electrical components.
③Bag: After dehumidification, pat the dust off, put the power cord and switch inside, then roll it into a tube and put it in a plastic bag for storage.
④Ventilation: The electric blanket that has not been used for a long time should be ventilated frequently, the electric blanket should be laid flat, and then energized for half an hour, which not only removes moisture but also kills insects, and can prolong the life of the electric blanket.
