ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a roasting device, and in particular, to a roasting device comprising a body, a bean-roasting chamber, a bean-entering cover, a front frame board, a front cover, connecting members, rear cover, fan, control panel, cooling device.
(b) Description of the Prior Art
Referring to
FIGS. 1 and 2
, there is shown a conventional roasting device comprising a body having a bean-roasting chamber
11
with a front cover
2
. A fixed filtering board
3
and a bean-entering cover
4
are also provided to the chamber
11
. The lower section of the chamber
11
is provided with manual control switch
6
and indicator
7
. The lower section of the chamber
11
is also provided with a collecting tray
1000
for collecting residue in the course of bean roasting. The bottom section of the collecting tray
1000
is provided with a fan
100
for quench the roasted bean
8
. A cooling device
15
with a cooling tray
10
provided at the cooling rod
101
is provided to the recessed region
12
of the body
1
. The central of the recessed region
12
is provided with a motor
13
such that the axle
131
protruded out of the recessed region. There are drawbacks with respect to the conventional roasting device structure.
For instance, the front cover
2
cannot be rapidly removed or opened and the chamber
11
therefore cannot be cleaned effectively. Secondly the oil fume cannot be reduced and the fume will cause pollution. In other words the conventional roasting device does not provide with an effective filtering apparatus to filter polluted flume. Thirdly, the cooling tray
10
is not secured between the tray
14
and the recessed region
12
and therefore the rotating of the axle
131
will drive the tray
14
and the cooling tray
10
. This will cause the cooling rod
101
to be ineffective and the roasted bean
8
cannot be stirred. In other words the cooling rod
101
can only be rotated but cannot stir the roasted bean
8
. The cooling effect is not significant. Accordingly it is an object of the present invention to provide an improved structure of a roasting device, which mitigates the above drawbacks.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a structure of a roasting device, wherein the bean-roasting chamber can be quickly cleaned and the exhausted gas within the chamber can be forced out and the oil fume particles can be filtered. Thus, the environment pollution is minimized, and the quality of bean roasting can be improved.
The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
