While dryers offer convenience, the high temperatures that may be generated on their surfaces do pose a risk of burns. However, modern dryers have been designed through a variety of technical means to prevent this problem. Here's a closer look at these anti-heat designs and how to use the dryer safely.

(1)、 dryer insulation layer

The Dryer's multi-layer insulation is a big part of the reason it doesn't burn.

1. Internal insulation material: in the dryer liner and between the external shell, usually filled with rock wool, glass wool and other efficient insulation material. These materials are filled with air voids, which are poor conductors of heat and effectively block the transfer of heat from the inside to the outside.

2. Metal shell and anti-hot design: the outer shell (usually metal material) itself also plays a certain role in heat dissipation and isolation. Some models of dryer in the door body and other key parts will also use special anti-hot net or heat insulation coating, to further reduce the surface temperature.

3. The importance of seal structure: Good Door Seal and shell sealing, to ensure that hot air is confined to the machine internal circulation, rather than leakage to the shell, which is essential to control the shell temperature.

(2)、Intelligent temperature control and cooling system

In addition to passive insulation, modern dryers use active controls to improve safety.

1. Temperature sensor and control system: most dryer built-in temperature sensor, real-time monitoring of internal temperature. When the temperature is too high, the control system will automatically adjust the heating power or stop heating, to prevent excessive accumulation of heat.

2. Cooling program: many dryers automatically run a cooling program for a period of time before the program ends. This process can effectively reduce the temperature of the inner cylinder and the clothing, so that it is safer and more comfortable when taken out.

3. Efficient cooling air duct: reasonable design of cooling air duct can ensure that the heat generated by the motor and other heat source components are quickly discharged, to avoid its impact on the shell temperature.

(3)、daily use of anti-hot matters needing attention

After understanding the machine design, the correct use of habits is also important.

1. Do not open the door immediately after the procedure: even after the procedure, there may still be residual heat inside the machine. It is recommended to wait a few minutes before opening the hatch to let the hot air dissipate naturally.

2. Pay attention to special procedures: drying such as rubber sole insole, waterproof fabric clothing and other items not easy to dissipate heat, it is recommended to choose low temperature drying mode, and pay attention to the program after the end of the machine temperature.

3. Keep the vents open: make sure there is enough space around the dryer, especially near the exhaust port, without debris accumulation to ensure smooth heat dissipation.

4. Special people need to be vigilant: there are children in the home or people with mobility difficulties, it is best to install the dryer is not easy to touch the location, and tell them the machine at work surface may be hot.

(4)、long-term security maintenance points

Regular maintenance is the key to ensure the continued effectiveness of the anti-burn design.

1. Clean the filter screen: clean the wool on the filter screen after each drying, which can not only improve the drying efficiency and protect the clothes, but also avoid the heat accumulation caused by the poor air duct.

2. Check the door seal: check the door seal regularly for aging, damage or contamination to ensure good sealing performance.

3. Pay attention to abnormal fever: if the machine shell temperature is abnormally high, or accompanied by burnt smell, should immediately stop using and contact the professional maintenance.

Conclusion

To sum up, modern dryers use layers of insulation, smart temperature control systems, and cooling designs to prevent their surfaces from overheating. And we users, it is mainly through the end of the process to wait until the door, to maintain ventilation and regular maintenance to further ensure safety.
