ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an electric roaster, particularly to one having two roaster trays mounted respectively on a base and a cover which are connected pivotally together.
2. Description of the Related Art
FIG. 1
shows an electric roaster
1
of the above-described type which includes a base
10
supporting a rectangular roaster tray
12
and a cover
20
holding another rectangular roaster tray
22
. The roaster tray
12
has an oil-collecting hole
121
adjacent to one side thereof, a plurality of parallel ribs confining grooves
122
, and an upwardly and laterally extending rim
123
. The surface of the roaster tray
12
is slanted downward to the oil-collecting hole
121
. A heating element
13
is attached to the roaster tray
12
at the bottom side thereof, and an oil-collecting receptacle
14
is provided below the hole
121
of the roaster tray
12
so as to collect the liquids such as oil and water, released from the food roasted on the roaster tray
12
.
The roaster tray
22
is also formed with a plurality of parallel grooves
221
and a rectangular rim
222
. In use, food is placed on the roaster tray
12
and the cover
20
is turned to the base
10
to close the roaster tray
12
with the roaster tray
22
. The rim
222
of the roaster tray
22
extends outwardly of the rim
123
of the roaster tray
12
when the roaster tray
12
is closed so that an enclosed space is formed between the roaster trays
12
and
22
for heating the food. The heating element
13
is energized by turning on a control unit
110
incorporating a timing device and mounted on the base
10
.
A disadvantage encountered in the aforesaid conventional roaster is that the roaster tray
22
cannot be used individually for roasting food as it is not provided with any means for heating and for collecting liquid released from roasted food. After the roasted tray
22
is open and turned away from the roaster tray
12
upon completion of roasting, the liquids, such as oil and water, emitted from the roasted food is accumulated in an indented part of the roaster tray
22
and has to be removed therefrom by rubbing off with a piece of oil absorbing cloth or tilting the roaster to cause the liquid to flow out. To clean the roaster tray
22
in such a manner is inconvenient.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a roaster of the above-mentioned type with an improved arrangement by which a roaster tray mounted on a cover of the roaster can perform a roasting operation independently of a roaster tray supported on a base housing and by which the liquids produced in the roaster trays held by both the base housing and the cover can be removed conveniently.
According to the present invention, an electric roaster comprises a base housing including a first roaster tray mounted thereon, and a first heating element attached to a bottom side of the first roaster tray. The first roaster tray includes a surface slanting downward in a first direction from one end to the other end of the first roaster tray, and an oil collecting hole formed in the first roaster tray adjacent to the other end of the first roaster tray. A collecting receptacle is disposed in the base housing below the oil collecting hole. A cover housing includes a second roaster tray mounted herein. One of the cover housing and the second roaster tray is connected pivotally to one of the base housing and the first roaster tray so that the first roaster tray is covered by the second roaster tray when the cover housing is turned to cover the base housing. The second roaster tray includes a surface slanting downward in a second direction parallel to the first direction from one end to the other end of the second roaster tray, an indented part disposed adjacent the other end of the second roaster tray, and an oil spout communicated with the indented part and extending into the base housing to communicate with the collecting receptacle.
