Circuit principle: Turn on the switch SA1, 220V is transformed by the transformer, and becomes DC after bridge rectification, which supplies power to the computer control board . Depending
on the food being grilled, the computer control panel sets the high or low temperature. At the same time, the time is set, and the relays Kl and K2
turn on or off the heaters EH1~EH4 according to the control of the computer board . After grilling, just turn off switch SA1.
