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.

BACKGROUND TECHNOLOGY Conventionally, this type of electric cooker
As shown in Publication No. 56580, it had a configuration as shown in FIG. That is, in FIG. 5, 1 is the cooking device main body, 2 is a lid provided on the cooking device main body 1 so as to be openable and closable, 3 is an upper frame provided on the upper part of the cooking device main body 1, and 4 is one side of the upper frame 3. 5 is a lid hinge portion located on both sides of the upper frame hinge portion 4; 6 is a lid cover that covers the lid hinge portion 5; 7 is a hinge cover that covers the upper frame hinge portion 4; 8
12 is a hinge shaft consisting of a shaft head 9, a shaft portion 10, and a shaft screw portion 11, and 12 is a non-circular hole 1 in the lid hinge portion 5.
It is a nut that fits into 3. 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 1
2 into the non-circular hole 13 of the lid hinge part 5,
In addition, the lid body cover 6 must be attached to the lid body 2, and the lid body 2 must be set after accurately aligning the hole positions of the lid body through hole 15 and the upper frame through hole 14 to the upper frame 3, and The hinge shaft 8 is inserted from the side opposite to the housing side of the nut 12, and is inserted into the lid through hole 15 and the upper frame through hole 14.
It is necessary to penetrate the nut 12 into the non-circular hole 13 and tighten the nut 12, which is a very complicated and time-consuming process. Furthermore, since the lid cover 6 is provided with a cover through hole 16 that is larger in diameter than the shaft head 9, this through hole 16 and the shaft head 9 are visible from the outside, resulting in a problem that the appearance is poor. Ta.

The present invention solves the above conventional problems,
To provide a lid opening/closing device which improves workability by eliminating complicated work and has an excellent appearance by making a hinge shaft invisible from the outside.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a rod-shaped hinge shaft that pivotally supports the lid on the cooker body, in the lid hinge located on one side of the lid. The outer cover is inserted into the through hole, and the outer cover is fitted onto the cover body from above, and the rod-shaped hinge shaft is fixed by sandwiching both end surfaces of the rod-shaped hinge shaft between the inner wall surface of the outer cover.

Effects According to this configuration, there is no need to accurately align and set the through-hole in the upper frame and the through-hole in the lid as in the past, and the rod-shaped hinge shaft can be inserted into the through-hole in the lid hinge. Moreover, since the outer cover is fitted onto the cover body from above and fixed by sandwiching both end surfaces of the hinge shaft between the inner wall surfaces of the outer cover, there is no need for tightening work as in the past. As a result, work efficiency can be improved, and since the hinge shaft is no longer visible from the outside, the appearance is also improved.

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 face 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;
6 is a dew tray detachably attached to the lid body hinge portion 25, and 28 is a rod-shaped hinge shaft provided in a through hole 29 of the lid hinge portion 25. Reference numeral 30 denotes an outer lid that covers the entire lid 21, and this outer lid 30 is attached to the lid 21 when attached to the hinge shaft 2.
8 is fixed. 31 is an L-shaped notch provided in the upper frame hinge portion 24, and 32 is an L-shaped notch provided in the upper frame hinge portion 24;
This is a protrusion provided on the top of 6.

To explain the operation in the above structure, the rod-shaped hinge shaft 28 is inserted into the through hole 29 of the lid hinge part 25, and the outer lid 30 is fitted onto the lid 21 from above to form an inner wall surface of the outer lid 30. The hinge shaft 28 is fixed by sandwiching both end surfaces of the hinge shaft 28 between the two ends. The hinge shaft 28 is inserted into the L-shaped notch 31 provided in the upper frame hinge portion 24 and is completely supported by the protrusion 32 provided on the upper part of the hinge car 26.
8 is the hinge axis 28 no matter what direction force is applied.
will not come off from the L-shaped cut portion 31.

Effects of the Invention As described above, according to the present invention, the rod-shaped hinge shaft that pivotally supports the lid on the cooking device main body is inserted into the through hole provided in the lid hinge located on one side of the lid, The outer cover is fitted onto the cover body from above and fixed by inserting both ends of the rod-shaped hinge shaft between the inner wall of the outer cover, so there is no need for conventional tightening parts such as nuts. Therefore, the number of parts can be reduced, and the tightening work can be eliminated, making it possible to significantly reduce the number of work steps. Also, in terms of appearance,
Since there is no need to provide a through hole in any part of the outer cover, the hinge shaft, through hole, etc. are not visible at all, and as a result, an excellent appearance can be obtained.
