Preferably, the height of the turnover pins is equal to that of the pins, the pins are provided with a round hole for connecting a ground wire, the width of each pin is equal to that of the turnover pin, the pin is close to one of the turnover pins, a gap is reserved between the pin and one of the turnover pins, and the width of the turnover pin close to the pin is smaller than that of the other turnover pins.

Preferably, the end edge of the turnover leg is bent to form a bent portion, the bending direction is the middle part of the heat insulation plate, and the central angle of the bent portion is greater than or equal to 90 degrees. The end edge of the turnover leg is in contact with the sealing ring, when the heat preservation plate is installed, the turnover leg can be bent by pressure to further compress the sealing ring, the end edge of the turnover leg is in a bent shape, so that a guide structure for bending the turnover leg is formed, the guide structure is in arc surface contact with the sealing ring, and the sealing ring cannot be damaged.

Preferably, the exhaust window is circular, and the circle center of the exhaust window is deviated to one side of the opening relative to the circle center of the heat insulation plate.

Preferably, the diameter of the vent window is larger than the width of the opening.

The utility model has the advantages that: the exhaust window is used for installing an exhaust valve and communicated with the opening, so that the aluminum plate is convenient to form, the flange is arranged on the periphery of the pulling plate, the flange is provided with a turnover pin, and the edge of the flange at the high part of the turnover pin is connected with the electric cooker cover; set up a ground pin on the turn-ups, ground pin is used for connecting the earth connection, avoids taking place electric leakage, electric shock danger.
