The heat insulating member 160 is disposed above the infrared heating element 141, and more particularly, above the reflecting member 143, to prevent heat of the infrared heating element 141 from being radiated to other heat-labile portions of the cover body 100, such as the printed circuit board PCB. The reflector 143 may be mounted to the thermal shield 160 by means such as snap fit, fastener fastening, etc. In the illustrated embodiment, the reflection member 143 may be provided with a plurality of locking legs, and the heat insulator 160 may be provided with locking holes corresponding to the locking legs. The clip is bent after passing through the clip hole to fix the reflecting member 143. The insulation 160 may be mounted to the liner 110 by means such as snaps, fastener securing, or the like.

In the present embodiment, the insulation panel 150 can be assembled between the liner 110 and the thermal insulation 160. Therefore, the liner 110 can provide an upward supporting force to the isolation plate 150, and the heat insulator 160 can press the isolation plate 150 downward, thereby limiting the movement of the isolation plate 150 in the vertical direction, enabling the isolation plate 150 to be firmly and reliably mounted in the cover body 100, and having a simple fixing manner and high assembly efficiency.

The outer circumference of the heat insulator 160 may be provided with a pressing part 161 protruding downward. The pot opening sealing ring 130 includes a sealing ring top 133 above the outer circumference of the isolation plate 150, and the pressing part 161 can press the sealing ring top 133 of the pot opening sealing ring 130. Thus, the pressing part 161 can press the isolation plate 150 and the pan opening sealing ring 130 downwards at the same time, so that the pan opening sealing ring 130 is more firmly and reliably mounted on the isolation plate 150 and cannot be separated from the isolation plate 150 due to deformation after long-term use.

As shown in fig. 6, the cover body 100 may further include a steam seal ring 170 for forming a steam passage. The steam sealing ring 170 is closer to the rear end of the cover body 100 than the infrared heating element 141. A temperature measuring device can be arranged in the steam channel.
