Electric chafing dish circuit diagram

The overtemperature fuse RF 1 in the circuit is a kind of temperature fuse tube, which looks like ordinary gray or black-gray carbon film resistor and mainly plays the role of overheating protection. When the electric chafing dish is in the state of being electrified, heated and dry-burned for a long time due to the failure of the thermostat, the temperature in the chafing dish will continue to rise after reaching the value that should have been cut off. If the temperature is too high, it will burn out the electric hot pot and even ignite the surrounding objects, resulting in a fire accident.

After setting RF 1, when the temperature rises to the rated value, RF 1 will fuse, and the power supply of the heating plate EH 1 will be cut off, so that the temperature will not continue to rise and gradually decrease, thus preventing the electric hot pot from burning out or fire accidents to some extent. Generally, the rated temperature of RF 1 is 150℃ ~ 250℃, and the specifications used by different electric hot pots are different, among which the specifications of 200℃ ~ 250℃ are more widely used.

Matters needing attention in the use of electric hot pot:

1. As the electric chafing dish is a high-power appliance, a grounded wall socket must be used, and the plug should be plugged tightly. Never use the universal socket with other electrical appliances at the same time. It's the first time to use electric hot pot, and finally see if the power supply can be reused by distributing plug.

2. Before use, be sure to wipe the water drops and sundries on the surface of the pot and the electric heating plate with a dry cloth, and then put the inner pot into the pot body to gently determine the position, so as to ensure that the inner pot is placed smoothly and has good contact with the electric heating plate. Otherwise, it will cause poor heat transfer and affect the normal temperature rise.

3. The position of electric hot pot is very important when it is used. Don't put it near an open flame, put it in a horizontal place. Otherwise, it is easy to burn out the electric hot pot or cause abnormal fever.
