  • [0024]
    In this preferred embodiment, the stop members 52 are mounted movably in the socket casing 33, and are disposed rearwardly of the lathes 51, respectively. Each of the stop members 52 has opposite first and second ends 522,521. The temperature sensor 43 of the plug 4 moves along a sensor passage during insertion of the plug 4 into the plug hole 333 in the socket casing 33 to come close to the tray unit 3. When the tray unit 3 is detached from the base member 2, as shown in FIG. 9, the stop members 52 are disposed at a stopping position, in which the first ends 522 of the stop members 52 overlap each other and are disposed at a position within the sensor passage, thereby preventing extension of the temperature sensor 43 through the sensor passage to come close to the tray unit 3. Upon mounting of the tray unit 3 on the base member 2, as shown in FIG. 8, the engaging parts 22 extend respectively through the apertures 334 in the side walls 332 of the socket casing 33 and push the second ends 521 of the stop members 52 such that the stop members 52 move in the transverse direction from the stopping position to an open position, in which the first ends 522 of the stop members 52 are disposed at a position outside the sensor passage, thereby permitting extension of the temperature sensor 43 of the plug 4 through the sensor passage to come close to the cooking tray 31. Two second urging members 520 are mounted respectively on the stop members 52, and are coupled to the socket casing 33 in such a manner as to urge, respectively, the stop members 52 to the stopping position (see FIGS. 5 and 9).
  • [0025]
    Each of the stop members 52 preferably has a U-shaped end segment that includes a bight portion 523 (see FIGS. 4 and 5) defining the first end 522 of a respective one of the stop members 52, and two opposite arm portions 523″ extending from two opposite sides of the bight portion 523 and defining a gap 5230 therebetween. The gaps 5230 between the arm portions 523″ of the U-shaped end segments of the stop members 52 are disposed outside of the sensor passage when the stop members 52 are disposed at the stopping position, and are disposed within the sensor passage to permit extension of the temperature sensor 43 therethrough when the stop members are disposed at the open position.
  • [0026]
    With the inclusion of the latches 51 and the stop members 52 of the safety device 5 in the cooking assembly of the present invention, undesired removal of the tray unit 3 from the base member 2 can be prevented when the plug 4 is inserted into the plug hole 333 in the socket casing 33, and insertion of the plug into the plug hole 333 in the socket casing 33 is prevented when the tray unit 3 is removed from the base member 2, thereby eliminating the aforesaid drawback associated with the prior art.
  • [0027]
    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.
