ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to roasting device, and in particular, a roasting device having a body with a heat dissipation seat at the lower portion.
(b) Description of the Prior Art
Referring to
FIGS. 1 and 2
, there is shown a conventional roasting device having a roasting chamber
11
and debris collection disc
1000
. There are numerous drawbacks found in convention device such as the front cover
2
cannot be opened and therefore cleaning is not convenient.
When the bean-roasting chamber
11
rotates, the roasting beans
8
are squeezed and the bean cover
4
may be pushed away or overflow. This is not convenient in used. The recess
12
at the lower section of the body
1
is provided with motor
13
and a protruded shaft center
131
mounted to the tray
14
. A cooling disc
10
having net hole is then connected to the cooling rod
101
. The rotation of the shaft center
131
allows cooling of the roasting bean
8
. However, the cooling disc
10
at the tray
14
and the recess
12
is not supported. After the motor
13
is rotated, there may be an engagement where the tray
14
and the cooling disc
10
are driven in the course of rotation. This will cause a failure in the cooling rod
10
and the roasting bean
8
cannot be triggered.
The conventional cooling rod
101
can have single side rotation which cannot push or stir the roasting bean
8
in the course of roasting. Besides the tray
14
and the cooling tray
10
are stacked and sealed spaced which does not allow rapid cooling. The spaced fan
100
has poor cooling effect and therefore it is time wasting which affects the quality of beans.
Further the manual control switch
6
and the single power indicator
7
are not accurate and therefore the quality and taste of the roasting beans
8
cannot be improved.
Furthermore, there is no protective device for the outside of the bean-roasting chamber and therefore there is a possibility that the user touches the high temperature bean-roasting chamber
11
.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an improved structure of a roasting device having a body, a cooling disc, a heat dissipation seat mounted below the body and a base seat provided with debris disc protruded from shaft center of the motor, characterized in that the base seat is provided with through holes and contains a fan, and the debris disc on the top portion of the fan is provided with through holes and a filter body is provided on the top of the through hole preventing object from falling, facilitating the cooling of roasted bean on the cooling disc of the roasting device.
Yet a further object of the present invention is to provide an improved structure of a roasting device, wherein the outside of the roasting chamber is provided with fastening hook having a protective frame provided with a fastener ring to prevent bum when directly in contact.
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.
