Specifically, the plate holder 110 includes a plate bottom portion 112, a plate transition portion 114, and a plate side portion 116, which are connected in series, and may correspond to a pot bottom portion 215, a transition portion 216, and a pot side portion 217 of a pot body 214. As shown in fig. 2, a central axis of the pot body 214 is indicated by a dashed line, a boundary between the pot bottom 215 and the transition portion 216 and a boundary between the transition portion 216 and the pot side portion 217 are indicated by a dashed line, the central axis of the pot body 214 passes through the pot bottom 215, an end of the pot side portion 217 far from the pot bottom 215 forms a pot mouth of the pot body 214, and the transition portion 216 is connected between the pot bottom 215 and the pot side portion 217.

The distance between the outer edge and the inner edge of the pan side 217 in the horizontal direction is related to the inclination of the wall surface of the pan side 217 and the extension length of the pan side 217 in the vertical direction, and is not limited herein. It is understood that tray bottom 112, tray transition portion 114, and tray side 116 correspond to tray bottom 215, transition portion 216, and tray side 217 of tray body 214, respectively, meaning that tray bottom 112, tray transition portion 114, and tray side 116 correspond to tray bottom 215, transition portion 216, and tray side 217, respectively, in the up-down direction, i.e., the projection of tray bottom 112 in the horizontal plane falls within the projection of tray bottom 215 in the horizontal plane, the projection of tray transition portion 114 in the horizontal plane falls within the projection of transition portion 216 in the horizontal plane, and the projection of tray side 116 in the horizontal plane falls within the projection of tray side 217 in the horizontal plane.
