Also, insulating cotton may cover the first via 41 to reduce heat from entering the insulating region 40 through the first via 41.

Further, a through hole (not shown) may be formed at the bottom of the heat insulation area 40, so that heat in the heat insulation area 40 can be dissipated through the through hole to further avoid temperature rise of the power connector 21 and the electric control board 22, and when condensed water is generated in the heat insulation area 40, the condensed water can be timely discharged through the through hole to avoid the influence of the condensed water remained in the heat insulation area 40 on normal use of the power connector 21 and the electric control board 22.

As shown in fig. 1, the cooking appliance may be configured as an appliance for heating the pot body 200 through the heating member 10 of the base assembly 100, such as an electric hot pot, an electric steamer, an electric stewpot, an electric rice cooker, etc., and the embodiment of the present utility model is not particularly limited herein.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
