Description
BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention relates to a structure of a grill and cage for an electric oven, and more particularly to one adapted to the oven with a turning grill/cage driven by a motor.

[0003] (b) Description of the Prior Art

[0004] Whereas the prior art of a grill/cage of an electric oven, such as disclosed in U.S. Pat. Nos. 6,076,453, 6,1402,065, 6,173,645, 6,240,838, 6,250,214 and 6,253,665, is essentially composed of a grill including two pans and one or two insertion rod. Said pans are combined with the insertion rod with a turning shaft provided to the outer side of the pan or at both ends of said insertion rod to turn around inside the oven. When in use, food is pierced through with the insertion rod before combining the pans and the insertion rod. However, they share the same defective that the food is not secured enough by the insertion rod, thus a consistent rotation is prevented. An even greater flaw is that if a cage is used, the grill must be inserted into the cage for use. Usually, more than one type of food is prepared, the operation of the cage and grill becomes not so convenient. In addition, the cage is not fixed in relation to the grill, resulting in insufficient strength of the cage and the grill as a whole, the rotation is vulnerable to be deflected. Lateral sliding of the cage also creates unnecessary noise. The absence of a partition in the case makes the food of smaller size receives uneven heats or gets overdone.

SUMMARY OF THE INVENTION

[0005] The primary purpose of the present invention is to provide a grill and cage structure for an electric oven. A gear is fixed to one side of the grill or cage and a turning shaft is each fixed to the outer side of the gear and that of the other side on the grill or the cage. Said turning shafts are inserted inside the oven and said grill comprises two turntables. An insertion rod is provided to the center of one turntable and a corresponding insertion hole is provided in the center of the other turntable. A wing bolt is connected to the outer side of the other turntable to secure both turntables in position when incorporated with the insertion rod placed into the insertion hole. Furthermore, a partition is provided inside the cage protruding toward the center of the cage to eliminate restriction to the variety of the food when the oven is in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Referring to FIGS. 1 and 2, a preferred embodiment of the grill (1) of the present invention is composed of two turntables (11, 12) and two rods (111, 121) respectively provided to the two turntables (11, 12). Both side panels of an oven (4) are each provided with a guide groove (41) at a certain inclination.

[0013] An insertion rod (112) is provided at the center of the turntable (11) penetrating through the turntable (11) and fixed to a gear (113). Two turning shafts (114, 115) are each respectively fixed to the outer side of the gear (113) and to the other end of the insertion rod (112). An insertion hole (122) corresponding to the insertion rod (112) is provided in the center of the turntable (12). A bracket (123) is provided to the outer side of the turntable (12). A hole (124) in the bracket (123) is provided to receive a wing bolt (125). The bracket (123) extends downward a bending plate (126) with an insertion hole (127) corresponding to the insertion rod (112). The insertion rod (112) from the turntable (11) is inserted into the insertion hole (127) and secured in place by tightening up the wing bolt (125) through the bracket (123) for both turntables (11, 12) to fix to each other. In practice, the rods (111, 121) and the insertion rod (112) with the food on are put together and the turning shafts (114, 115) are placed into the guide grooves (41) of the oven (4).

[0014] As illustrated in FIGS. 3 and 4, a cage of the present invention can be made in square and in circular. The square cage (2) comprises a main portion (21) and a cover (22). The cover (22) is fixed to the main portion (21) with a snap (221) and a handle (222). A turning shaft (211) is fixed to the one side of the main portion (21) and a gear (212) is fixed to the other side of the turning shaft (211). Another turning shaft (213) is fixed to the outer side of the gear (212). In use, the turning shafts (211, 213) are inserted into the guide grooves (41) in the oven (4).

[0015] FIGS. 5 and 6 show another preferred embodiment of the circular cage (3).

[0016] The circular cage (3) comprises a main portion (31) and a cover (32). The main portion (31) is covered up by the cover (32), and a turning shaft (312) is fixed to the outer side of the main portion (31). A turning shaft (312) is fixed to the outer side of the main portion (31) and a bolting ring (311) is provided on the edge of the opening end of the main portion (31) opposite to the turning shaft (312). A partition (313) protruding toward the center inside the main portion (31) is provided on the inner wall of the main portion (31). A snap (321) provided on the outer edge of the cover (32) locks up the bolting ring (311) for the cover (32) to cover up the main portion (31). A gear (322) is fixed to the outer side of the cover (32) and a turning shaft (323) is fixed to the outer side of the gear (322). In practice, both of the turning shafts (312, 323) are inserted into the guide grooves (41) of the oven (4).

[0017] As disclosed above, either in the grill (1), square cage (2) or circular cage (3), the present invention has provided turning shafts on both ends of the main portion, and a gear on one side. Said cage and grill can be separately used. The structure offers better strength as a whole because that the relative locations among all members are fixed without restricting the practical use of the oven. It also warrants consistent rotation of the grill and cage, and the partition (313) in the circular cage (3) helps even distribution of heats to the food.
