It should be noted that, in the present invention, the directional terms "upper" and "lower" are those directions determined based on the cooking utensil in a state in which the lid body is closed on the pot body while being placed upright.
As shown in fig. 1 and 2, the infrared heat generating component 100 mainly includes an infrared heat generating element 110, a reflection cover 120, and a heat sensitive sensor 130. The infrared heating element 110 serves to radiate infrared rays to the cooking space. The reflection cover 120 covers one side (specifically, an upper side) of the infrared heating element 110 to reflect the infrared rays radiated from the infrared heating element 110 toward the other side, that is, to reflect the infrared rays radiated from the infrared heating element 110 downward to enter into the cooking space. The heat sensor 130 is disposed on a side (specifically, an upper side) of the reflection case 120 facing away from the infrared heat generating element 110. The thermal sensor 130 includes a thermistor.
Since the material of the casing of the heating region of the infrared heating element 110 is generally quartz glass, it is inconvenient to install the thermal sensor 130.
