Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lid opening/closing device for a cooking appliance in which a lid is pivotally attached to one side of a cooking appliance body so as to be openable and closable.

Conventional technology A conventional electric cooker of this type is, for example, the
As shown in Publication No. 56580, it had a configuration as shown in FIG. In the figure, 1 is the main body of the cooker, 2 is a lid provided on the main body 1 of the cooker so that it can be opened and closed, 3 is an upper frame provided on the upper part of the main body 1 of the cooker, 4
5 is an upper frame hinge provided on one side of the upper frame 3, 5 is a lid hinge provided on the lid 2 to correspond to the upper frame hinge 4, and 6 is a lid cover that covers the lid hinge 5. , 7 is a hinge cover that covers the upper frame hinge part 4, 8
12 is a rod-shaped hinge rod consisting of a shaft head 9, a shaft portion 10, and a shaft screw portion 11; and 12 is a nut that is fitted into a non-circular hole 13 of the lid hinge portion 5. Further, the upper frame hinge portion 4 is provided with an upper frame through hole 14, and the lid hinge portion 5 is provided with a lid through hole 15.

Problems to be Solved by the Invention However, in the above conventional configuration, the nut 12 is assembled into the non-circular hole 13 of the lid hinge portion 5, the cover 6 is attached to the lid 2, and the lid 2 is placed on top. When setting in frame 3, cover through hole 15
It must be set after accurately aligning the hole position of the upper frame through hole 14. In addition, the hinge shaft 8 must be inserted from the side opposite to the storage side of the nut 12, passed through the lid through hole 15 and the upper frame through hole 14, and then tightened onto the nut 12 that fits into the non-circular hole 13. However, the work was complicated and extremely time consuming. Further, since the cover 6 is provided with a cover through hole 16 that is larger in diameter than the shaft head 9, the through hole 16 and the shaft head 9 are visible from the outside, which causes the problem of poor appearance. It was hot.

The present invention solves these problems,
To provide a lid opening/closing device capable of improving workability by eliminating complicated work and having an excellent appearance by making a hinge shaft invisible from the outside.

Means for Solving the Problems In order to solve the above problems, the present invention incorporates a rod-shaped hinge shaft into the lid body in advance, and then attaches it with an outer lid that covers the upper part of the hinge shaft fixing part of the lid body. The hinge shaft is attached to a notch provided in the upper frame hinge portion, and is configured to be pivotally supported by a hinge cover.

Function: According to this configuration, there is no need to accurately align and set the through holes in the upper frame and the lid as in the past, and since the rod-shaped hinge shaft is pre-assembled in the lid, tightening work etc. As a result, work efficiency is improved, and since the hinge shaft is no longer visible from the outside, the appearance is also excellent.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 4.

In the figure, 21 is a lid provided on the cooker main body 22 so as to be openable and closable, 23 is an upper frame provided on the upper part of the cooker main body 22, 24 is an upper frame hinge provided on one side of the upper frame 23, and 25 is an upper frame. This is a lid hinge portion provided on one side of the lid body 21 so as to correspond to the frame hinge portion 24.
26 is a hinge cover that covers the upper frame hinge portion 24 and the lid hinge portion 25; 27 is a hinge cover 2;
A dew tray 28 is detachably attached to 6, and 28 is a rod-shaped hinge shaft provided in the lid through hole 29 of the lid hinge portion 25. Reference numeral 30 denotes an outer cover that covers the entire cover 21, and when attached to the cover 21, the outer cover 30 covers both end surfaces of the hinge shaft 28 and both sides of the cover through hole 29, and 31 is an upper frame hinge. This is a notch provided in the portion 24.

To explain the operation in the above configuration, the rod-shaped hinge shaft 28 inserted into the lid through hole 29 of the lid hinge part 25 and fixed by the outer lid 30 is connected to the notch 31 provided in the upper frame hinge part 24. inserted into
Since the hinge shaft 28 is completely supported by the hinge cover 26, the hinge shaft 28 will not come off the notch 31 even if a force is applied to the hinge shaft 28 in any direction.

Effects of the Invention As described above, according to the present invention, after the rod-shaped hinge shaft is assembled in the lid body in advance, this hinge shaft is attached to the notch provided in the upper frame hinge portion, and is pivotally supported by the hinge cover. Because of this structure, conventional tightening parts such as nuts are no longer necessary, and as a result, the number of parts can be reduced, and there is no tightening work, which improves work efficiency.
In addition, since there is no need to provide a through hole in any part of the outer lid, the hinge shaft and the like are not visible, and as a result, an excellent appearance can be obtained. Furthermore, since the hinge shaft of the lid can be attached by covering it with the outer lid, there is no need to tighten nuts or the like, and the ease of assembly can be improved.
