ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a toaster oven, particularly to one having a door placed under a housing of the roaster oven after opened, and a rotating frame horizontally placed in and taken out of the housing for rotating food on the frame, convenient to handle, not taking much space for roasting food in a balanced way, and extremely safe to use.
A common conventional roaster oven generally has a door pivotally connected to a front side of a housing and pivotally opened outward for putting in or taking out food to be toasted and then the door is closed in using. This simple structure has been in use for conventional roaster ovens for long. However, the conventional roaster ovens shown in
FIGS. 1 and 2
have an disadvantage that when the door
20
is opened for putting in or taking out food for roasting, the door
20
may automatically swing toward the front side of the roaster oven
10
as shown in
FIG. 1
, striking on an elbow of a user. In case of taking out just roasted food, the elbow may be burned by the highly hot door
20
and roasted food may fall down by sudden jerking of the arm of the user if worse. In case of the door swings open the most outward, it may take much space in a kitchen as shown in
FIG. 1
, possible to collide with a person passing by, and if the collide force is too great, the door may be pushed back to the front side of the oven
10
. But if the push force against the door
20
should be excessively large, a pivotal shaft of the door may break, letting the door
20
fall off the oven
10
.
In addition, the conventional roaster ovens have a semicircular support frame
101
, a non-circular insert groove
103
formed in one side, and a cylindrical base
102
formed in opposite side and rotated by a motor
104
. Then a rotating frame
30
(or a single pricking rod) for holding or pricking food is provided in the oven as shown in
FIG. 2
, having two rotating discs
301
located at two opposite sides and some pricking rods
302
. A first rotating disc
301
at one side of the supporting frame
101
has a circular postal member
303
and a second rotating disc
301
at one side of the cylindrical base
102
has a non-circular insert rod
304
formed to extend horizontally outward from a center. Then if the rotating frame
30
is to be put in the oven
10
, the rotating frame has to be inclined a little to be pushed in the oven
10
, with the insert rod
304
fitting in the insert groove
102
of the cylindrical base
102
, and then with the post member
303
placed down flatly on the support frame
101
. If the rotating frame
30
is to be taken out of the oven, is has to be handled with the action reverse to that just mentioned.
The structure of the conventional roaster oven cannot be said to be convenient to handle with no lighting and a narrow interior space, and in addition, the insert groove
103
of the cylindrical base
102
and the insert rod
304
of the rotating discs
301
are not circular not easy to be aligned to each other for inserting, and moreover, the insert hole
103
is not large, often needing much time in inserting the insert rod
304
. Further, a heater in the oven
10
may collide the rotating frame
30
in an inclined angle, if carelessly moved, and in taking out food roasted on the rotatable frame
30
, the post
303
of the rotatable disc
301
has to be pushed up a little, causing danger of a hand touch the still hot heater and burned, even if the heater is cut off.
Another disadvantage of the conventional roaster oven is that the all pricking rods
302
are fixed between the two rotatable discs
30
, and food of large dimensions such as a whole chick or a whole duck and food of small dimensions such as cut meat, corn, etc. are pierced through the pricking rods
302
. Then the inside of food is always farther away from the heater even if the rotating discs
30
are rotating, so the outside of food is always roasted better than the inside of food that is not directly roasted. Then food may have different color in the outside portion and the inside portion owing to unbalanced roasting. Then the main reason is the pricking rods
302
not self rotating between the two rotating discs
301
.
SUMMARY OF THE INVENTION
A first objective of the invention is to offer a roaster oven having a door placed under a housing after opened, preventing the door from swinging with a pivot so as to avoid accidents, and reducing the space for using the oven with big convenience.
A second objective of the invention is to offer a roaster oven having rotating frame for placing food therein possible to be put in and taken out of the oven, not touching a hot heater in handling and having high safety in use.
A third objective of the invention is to offer a roaster oven having plural piercing rods able to rotate between two rotating discs so as to let every portion of food pierced on the piercing rods face the heater alternately to get roasted in a balanced way.
The feature of the invention is a housing, two support bases at two sides of the housing bottom, a pair of auxiliary rollers located in the inner side of the front end of the two support bases, a pair of slide rail made integral in the interior of the two support bases, and a slide roller pivotally connected to the two sides of the bottom of the door and laid on the pair of the slide rails. When the door is closed, the slide rollers of the door is located at the front end of the slide rails, and when the door is swung open with the slide rollers as fulcrums, with the two side edges laid on the auxiliary rollers and the slide rollers sliding along the slide rail to the bottom of the housing to let the door move to under the housing by means of the movement of the auxiliary rollers.
