• connection hole 41 allows to create the depression inside the cooking chamber 30 because it connects the latter with the vacuum pump 14H.
• a ninth embodiment of a cooking apparatus according to the invention is described, denoted in its entirety by the reference number 101.
• the cooking apparatus 101 comprises the optical sensor 21 B for the remote detection of the temperature inside the cooking container 12.
• the optical sensor 2 1 B is located in a suitable seating 43 B made on the base I I .
• the seating 43 B is made in a portion of the base 1 1 which faces the cooking container 12 and adjacent to the zone in which the interface means 24 and the control and command unit are positioned.
• the cooking apparatus can comprise, instead of the optical sensor 21 B, an optical sensor 21C analogous to the optical sensor 21 B but located in a respective seating 43 C made on the lid 17.
• the optical sensor 21 C associated with the lid 17 is therefore facing the cooking chamber 30 and the food 50 contained therein, so as to be able to effectively detect the temperature thereof.
• the heating means 13 can comprise any of the heating means 13B, 13C, 13D, 13E, 13F described with reference to figs. 2-6.
