21


can be turned rearward from the closed position to an open position, in which a respective one of the upper halves


21


generally perpendicular to the lower grill unit


1


, as best shown in FIG.


1


. Since the particular connection between the upper halves


21


and the lower grill unit


1


is not pertinent to the claimed invention, a detailed structure of the same is omitted herein for the sake of brevity.




Each of the control switches


3


is operable in a known manner so as to control actuation and cooking temperature of a respective one of the lower cooking members


32


of the lower grill unit


1


and the upper cooking member


31


of a corresponding one of the upper halves


21


. An insulator spacer


14


is disposed between the lower cooking members


32


so as to form two isolated cooking spaces that are confined by the upper halves


21


and the lower cooking members


32


. In this embodiment, the control switches


3


are mounted on the lower grill unit

,


325


.




Preferably, the cooking surface


321


S of the cooking plate


321


inclines gradually from the rear side toward the front side of the lower grill unit

,


325


therein.




Since adjacent front ends of the second grill ribs


325


are spaced by the downwardly curved portion


3242


of the first grill rib


324


, cleansing operation therebetween is consequently facilitated.




With this invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is therefore intended that this invention be limited only as indicated in the appended claims.
