Waterproof electromagnetic oven

The utility model relates to the field of household electrical appliances, in particular to a waterproof electromagnetic oven. A metal strip (301) is arranged at the periphery of a control board (305) of the waterproof electromagnetic oven, and the metal strip (301) is one of metal sheets (101). Three sides of the control board (305) are surrounded by the metal strip (301). In addition, a controller (103) and a signal processing circuit (102) are arranged on the control board (305). The metal strip (301) is connected with the controller (103) through the signal processing circuit (102). The metal sheet is arranged, and the change of the capacitance of the metal sheet is detected through the controller for judging whether water enters the electromagnetic oven or not. If yes, the controller can choose to turn off the electromagnetic oven and to alarm for achieving the purpose of protecting the electromagnetic oven. Further, the use of the electromagnetic oven is safer.
