Description
FIELD OF THE INVENTION
[0001] The present invention relates to steam oven doors, and more
particularly to a hinge device of a steam oven door capable of
capable of preventing interference between the oven door and the
water tray, wherein the oven door of the present invention will not
interfere with the water tray. The oven door and the outer lateral
wall of the water tray can be on the same plane, making the outlook
of the present invention more visually appealing.
BACKGROUND OF THE INVENTION
[0002] Referring to FIG. 1, a steam oven of the prior art has a
boxy case 10 having a bottom water tray 11. To open the boxy case
10, the oven door 12 is rotated downward about the pivotal side
along the bottom thereof, so that the food inside the boxy case 10
can be taken out. However, the oven door 12 being rotated will
inevitably interfere with the water tray 11; therefore, the outer
edge of the water tray 11 is located under the boxy case 10 with a
distance from the pivotal side of the oven door 12. This
configuration is inconvenient to people who want to reach the water
tray 11. Further, since the interface between the water tray 11 and
the oven door 12 is recessed, the outlook of the steam oven will be
negatively influenced.
SUMMARY OF THE INVENTION
[0003] Accordingly, the primary objective of the present invention
is to provide a hinge device of a steam oven door capable of
preventing interference between the oven door and the water
tray.
[0004] A hinge device of a steam oven door comprises a mount
provided with a slide slot thereon, which is installed on an inner
lateral wall of an oven case. A roller wheel is slidably mounted in
the slide slot. One side of the mount is pivotally installed with a
rotary beam provided with a spring; the free end of the spring is
fixed on the lateral wall of the oven case. The opposite side of
the mount is provided with a push beam with one end pivotally
connected to the roller wheel and the rotary beam. The rotary beam
is pivotally connected to a link beam with second end pivotally
connected to a curved element, whose one end is in turn pivotally
connected to the mount. The other end of the curved element is
pivotally connected to a transmission beam. One end of the push
beam is pivotally connected to the transmission beam, and the other
end is connected to the inner wall of the oven door. Thereby, the
oven door is mounted on the front side of the steam oven.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] The various objects and advantages of the present invention
will be more readily understood from the following detailed
description when read in conjunction with the appended
drawings.
[0013] Referring to FIGS. 2, 3, and 4, a hinge device of a steam
oven door accordingly to the present invention comprises a mount
20, a rotary beam 3, a push beam 4, a link beam 5, a curved element
6, a transmission beam 7 and an oven door 8. The mount 20 is
provided with a slide slot 21 in which a roller wheel 24 is
slidably mounted. The mount 20 is further provided with a pair of
through holes 22, 23. The rotary beam 3 is pivotally connected to
the roller wheel 24 on a first side of the mount 20 by inserting a
pivot piece 30 through a through hole 31 on the rotary beam 3 and
the through hole 22. The rotary beam 3, having three through holes
31, 32, 33 and an upper ear part 34, is linked to a first end of a
spring 35 hooked at the ear part 34. A second end of the spring 35
is fixed on a lateral inner wall of the oven case 2. The push beam
4, having a pair of through holes 40, 41, is pivotally attached on
a second side of the mount 20 by inserting a pivot piece 36 through
the through hole 33, the roller wheel 24 and the through hole 40. A
first end of the push beam 4 is pivotally connected to the roller
wheel 24 and the rotary beam 3. The link beam 5 has a first end
pivotally connected to the bottom end of the rotary beam 3 by
inserting a pivot piece 50 through a through hole 51 and the
through hole 33. The curved element 6 has a first end pivotally
connected to a second end of the link beam 5 by inserting a pivot
piece 60 through a through hole 61 and the through hole 23, so that
the curved element 6 is attached to the mount 20. The transmission
beam 7 is pivotally connected to a second end of the curved element
6 by inserting a pivot piece 63 through a through hole 70 and
another through hole 64. The transmission beam 7 is further
pivotally connected to a second end of the push beam 4 by inserting
a pivot piece 71 through a through hole 72 and the through hole 41.
The oven door 8 to which a main section of the transmission beam 7
is attached.
[0014] To use a steam oven door equipped with the present
invention, as shown in FIGS. 5 and 6, when the oven door 8 is being
opened, the transmission beam 7 attached on the inner wall of the
oven door 8 will drive the curved element 6 to rotate about the
pivot piece 60, and the push beam 4 is pulled by the transmission
beam 7, thereby driving one end of the rotary bean 3 and the roller
wheel 24 to slide along the slide slot 21. Accordingly, the rotary
beam 3 will urge the link beam 5 to stretch the spring 35, and the
other end of the link beam 5 will be driven by the curved element
6. When the oven door 8 is opened slightly, it will be supported by
the push beam 4 and the curved element 6 to be lifted upward, as
shown in FIG. 6, whereby the bottom side of the oven door 8 will
not collided with the water tray 25 disposed on the bottom of the
oven case 2. As the oven door 8 is further opened and extended
outward, the transmission beam 7 will continue to drive the curved
element 6 and the push beam 4, whereby the rotary beam 3, the
curved element 6 and the push beam 4 will move in accordance with
the curve defined by the slide slot 21. Therefore, the outward flip
of the oven door 8 will also follow the curve defined by the slide
slot 21 and will not interfere with the water tray 25. The bottom
side of the oven door 8 and the outer side of the water tray 25 can
be designed to be close together, achieving a better outlook of the
steam oven.
[0015] According to the above description, the present invention
has the advantages as follows.
[0016] 1. The oven door of the present invention will not interfere
with the water tray.
[0017] 2. The oven door and the outer lateral wall of the water
tray can be on the same plane, making the outlook of the present
invention more visually appealing.
[0018] The present invention is thus described, and it will be
obvious that the same may be varied in many ways. Such variations
are not to be regarded as a departure from the spirit and scope of
the present invention, and all such modifications as would be
obvious to one skilled in the art are intended to be included
within the scope of the following claims.
