ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a backing oven with a movable up-and-down cover, particularly to one having a cover movable up-and-down according to the size of an object to be baked by pressing a press button in an immovable grip to press inward an insert member positioned in a side wall of the cover so that the cover may be raised up or lowered down to close up a housing. Thus, the interior space of the baking oven can be adjusted to suit the size of food to be baked, saving baking time needed and electric power used.
A known conventional baking oven shown in
FIG. 1
, generally has a housing
10
of a case shape, and a front cover
11
provided to open or close up a front side, a hollow chamber in the housing
10
, plural electric heating tubes
12
fixed in the housing
10
, and a support rod
13
for pricking through food to be baked. As the conventional baking oven has a constant inner size for baking, whether the food is large or small, almost the same baking time and almost the electric power is needed, resulting in waste of time and electric power.
SUMMARY OF THE INVENTION
The objective of the invention is to offer a baking oven with a movable up-and-down cover to adjust an inner hollow chamber of a baking oven according to the size of food to be baked, so as to save baking time and electric power used.
The feature of the invention is a movable up-and-down cover to open or close up an open upper side of a housing, an immovable grip fixed respectively to two side walls of the cover, and a press button provided in each grip, and a connect rod connected to one end of the press button, and a coil spring positioned in each grip to push the press button back after being pressed. The other end of the connect rod has two pushers of a sloped surface and a insert hole are bored between the two pushers, an insert member positioned in each of two opposite side walls of the cover and extending to engage one of plural position insert holes of the position means fixed on two opposite side walls of the housing. Then the insert members may be pushed inward to disengage from one of the plural position insert holes by pressing the press buttons to let the cover move up and down. The height of the cover is adjusted by moving up or down relative to the housing and then release the press button, then the insert members are pushed outward to engage another position insert hole of the position means, securing the cover in its position, altering the size of the inner hollow chamber of the baking oven for placing food therein.
