Description

[Detailed Description of the Invention] The present invention relates to a cooking device such as a rice cooker, and particularly relates to a back cover attachment device for closing a bottom opening of an outer shell.

Embodiments of the present invention shown in the drawings will be described in detail below. Reference numeral 1 denotes an outer shell of, for example, a rice cooker, which has a circular opening 2 on the bottom surface, and a plurality of, for example, four, locking holes 3, 3, etc. are formed at the periphery of the opening 2, and are further diagonally positioned. Screw holes 4 are formed near the two locking holes 3. Reference numeral 5 denotes a back cover that closes the opening 2 of the outer body 1, and a plurality of pieces, for example 4
Fixing holes 6, 6... are formed, and small diameter through holes 7, 7 are formed on both sides of each fixing hole 6. Reference numeral 8 denotes a support leg made of synthetic resin having a fixing hole 9 that matches the fixing hole 6 of the back cover 5, and integrally molded with detent pins 10 to be inserted into the through holes 7.
When the through holes 7, 7 and the locking pins 10, 10 are fitted, it is fixed to the back cover 5 by a stopper 11, such as a rivet, that penetrates through both the fixing holes 6, 9 so as to protrude outward from the outer periphery. has been done. The support leg 8 has a hook-shaped locking protrusion 12 at a portion that protrudes outward from the back cover 5.
are integrally molded, and an insertion hole 13 is formed therein.
Reference numeral 14 denotes a mounting angle for supporting the temperature fuse 15, which is fixed onto the upper surface of the back cover 5 using the stopper 11, and is prevented from rotating by the rotation prevention pins 10 of the supporting legs 8.

The present invention has the above-mentioned configuration, and the back cover 5 is attached as follows. First, the camera back 5 has a second
As shown in the figure, attach the support leg 8 to a fastener 11 such as a rivet.
It is fixed integrally. In this state, the supporting leg 8 is fixed by one stopper 11;
Rotation is prevented by fitting the through hole 7 and the rotation stopper pin 10, and the predetermined state is reliably maintained without causing any positional deviation.

Next, the outer body 1 is attached to the back cover 5 to which the supporting legs 8 are fixed.
With the opening 2 of each support leg 8 closed and the locking protrusion 12 of each support leg 8 inserted into each locking hole 3, the outer body 1 and the back cover 5 are relatively rotated, and the locking protrusion 12 is inserted into the locking hole 3. As shown in FIG. 1, it is engaged with the inner surface of the outer shell 1. However, in this state, the supporting leg 8 (4) is inserted into the screw hole 4 of the outer shell 1.
The insertion holes 13 (two of the two) match, and screws (not shown) are screwed into the screw holes 4 through the insertion holes 13, thereby completing the installation of the back cover 5.

Incidentally, if the temperature fuse 14 is attached using the stopper 11 as in the above-mentioned embodiment, there is no need for special parts for attaching the temperature fuse 14, which reduces the number of parts and improves workability. I can do it. In addition, by narrowing the distance between the support legs 8 and 8 located on both sides of the hinge mechanism 16, which is pivotally installed at the upper end of the outer body 1 so that the top cover can be opened and closed, the device can be prevented from being unbalanced in weight when the top cover is opened. can prevent accidental falls.

As described above, according to the configuration of the present invention, there is no need to screw all the support legs to the outer shell when attaching the back cover, and the assembly work can be significantly improved by reducing the number of screw-fastening points. It becomes certain. In addition, the supporting legs are fixed in a non-rotating state with a single stopper on the back cover, so they will not shift, so when inserting the locking protrusions of all the supporting legs into the locking holes of the outer shell at once, It can be easily inserted without the need for positioning each time, and the workability is improved, which is extremely useful in practice.
