Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention is related to an oven and in particular to one having a roasting cage which can be taken out of the casing as required thereby facilitating the removal of the food on the roasting cage and preventing the user from being injured by the hot casing of the oven.




2. Description of the Prior Art




Referring to

FIGS. 1 and 2

thereof, the conventional oven generally includes a casing


3


, a stick


1


and a pair of forked members


2


. The stick


1


is formed with a first recess


11


at one end and a second recess


12


at the other. The forked member


2


has a tubular body and a wing-like member


21


mounted on the tubular body. The tubular body of the forked member


2


is fitted over the stick


1


and fixedly mounted on the stick


1


by a screw


22


extending through the tubular body to bear against the stick


1


. The stick


1


together with the forked members


2


is mounted within the casing


3


, with its two ends engaged with two fixed seats


31


and


33


. The fixed seat


33


is drivingly connected with a motor


30


. The stick


1


cannot be taken out of the casing


3


after the oven is assembled. Hence, one will easily be injured by the hot casing


3


when taking out a hot roasted chicken from an oven. Furthermore, it is difficult to take out or mount a chicken on the stick within the casing


3


thereby often causing the forked member


2


from disengaging from the chicken


10


and dropping down the chicken


10


and therefore making the chicken directly contact the heater to cause a fire accident. In addition, it will be very inconvenient to clean the interior of the oven so that the food residue will allure cockroaches, ants, mice, . . . etc. to enter into the oven thereby often spreading diseases inadvertently.




Therefore, it is an object of the present invention to provide an improvement in the structure of an oven which can obviate and mitigate the above-mentioned drawbacks.




SUMMARY OF THE INVENTION




This invention is related to an improvement in the structure of an oven.




According to a preferred embodiment of the present invention, an oven includes a housing, two supporting plates mounted at two opposite inner sides of the housing, each of the supporting plates having an upper edge formed with a first recess at an intermediate portion of the upper edge and a second recess close to an outer end of the upper edge, a roasting cage having two circular discs at two opposite sides thereof, each of the circular discs provided with an outwardly extending axle at a center thereof and a plurality of slots at a circumferential edge thereof, and a plurality of sticks each being fitted between two aligned slots, the axle being configured to be received in any one of the first and second recesses, a driven gear fixedly mounted on an axle of one of the circular discs, a motor mounted on an inner side of the housing and provided with an output shaft on which is mounted a driving gear meshed with the driven gear, a heater fixedly mounted on an inner side of the housing, and a lid openably engaged with the housing.




It is the primary object of the present invention to provide an improved oven of which the roasting stick can be taken out of the casing as required thereby facilitating the removal of the food on the roasting stick and preventing the user from being injured by the hot casing.




It is another object of the present invention to provide an improved oven which can be easily cleaned and kept sanitary.
