(12) By means of the hinge shafts 7 that intersect, the two cooker covers 3 do not interfere with each other during opening and closing, so they are easy to open and would not be easily stuck. At the same time, only a small gap 7 is maintained between the two cooker covers when they cover the liners, not only ensuring separation of the two liners 2 without the food cooked therein affecting each other, but also reducing the volume of the cooker body 1 to the largest extent so as to save the kitchen space. In addition, the cooker body 1 is provided with two first inner cavities 11 for receiving the two liners 2. The two first inner cavities 11 are mutually separated via a thermal insulation plate 9 to allow them to separately heat the food at the same time, the cooking efficiency is therefore increased. Moreover, the cooperation between the protrusions 401 and the snapping groove 313 and the symmetrical arrangement of the two protrusions 401 can prevent incorrect assembling of the two sealing members 4. The sealing members 4 can be easily and quickly assembled after being cleaned and provide good sealing effects. This not only provides excellent ease of use, but also prevents any potential safety hazard that may be caused by the incorrect assembling.

(13) Of course, in order to better distinguish the two liners 2 and prevent misuse, the liners 2 may be arranged such that they are symmetrical relative to the center of the cooker body 1 and have a non-equilateral polygon or non-circular shape.
