The utility model provides a cover body and a cooking appliance. The cooking appliance according to the present invention may be an electric rice cooker, an electric pressure cooker or other cooking appliances, and may have various functions such as cooking porridge, cooking soup, etc. in addition to the function of cooking rice.
The cooking appliance mainly includes a pot body (not shown) and a cover 100, and the cover 100 is openably and closably disposed above the pot body. An inner pot (not shown) is provided in the pot body, and a cooking space may be formed between the cover body 100 and the inner pot when the cover body 100 is closed over the pot body. The pot body is substantially in the shape of a rounded rectangular parallelepiped and has a cylindrical-shaped receiving portion. The inner pot may be configured to be freely put into or taken out of the receiving part to facilitate cleaning of the inner pot, or may be configured to be fixed in the pot body so as not to be taken out of the pot body. The inner pot is generally made of a metal material for containing a material to be heated, such as rice, soup, etc.
In addition, a heating device is also arranged in the cooker body, and the heating device can be positioned below the inner pot to heat the food in the inner pot. It should be noted that, in the present invention, the directional terms "upper" and "lower" are those determined based on the cooking utensil in a state of being placed upright with the lid body 100 covering the pot body.
As shown in fig. 1 to 3, the cover body 100 mainly includes a face cover 110, a control circuit board 120, an infrared heating element 130, a reflection cover 140, and a heat insulation board 150.
The control circuit board 120 is disposed on the face cover 110 for controlling a cooking operation of the cooking appliance.

The projections of the cover main body portion 141 and the control circuit board 120 on the same horizontal reference plane at least partially overlap.
Since the infrared heating element 130 generates a large amount of heat and infrared rays when operating, the temperature rise of the control circuit board 120 is high when the infrared heating element 130 operates, and the control circuit board 120 may be damaged. In the present invention, by disposing the thermal insulation board 150 between the infrared heating element 130 and the control circuit board 120, the temperature of the control circuit board 120 can be prevented from being high.
