The gaps 10C and 10D for arranging the flexible flat cable 30 extending straight from the lower part to the gap 10F between the cord reel 65 and the outer case 7 are formed.

<About the electrical connection between the microcomputer board 50 on the lid 2 side and the control board 60 on the rice cooker body 1 side by the flexible flat cable 30: see FIGS. 2 to 5>
In this embodiment, as the electrical wiring material, for example, a flexible flat cable 30 in which the middle of the wiring portion is completely folded in half is used as shown in FIG. 4, for example, as shown in FIGS. 2 and 3. One end side 30a is arranged on the microcomputer board 50 side in the lid 2, while the other ends 30e and 30f are arranged on the control board 60 side in the rice cooker main body 1.

That is, the flexible flat cable 30 is configured as shown in FIG. 4, and one end side 30a thereof is the lower surface of the upper plate 21 in the lid 2, specifically, the steam cap storage groove. It is arranged between 21b and the frame member 26 and the lower plate 22 (poly cover), and between the electrical component storage groove 21a and the lower plate (poly cover) 22, and a connector portion (not shown) on the tip side thereof is arranged. It is connected to the connector 16 at the bottom of the electrical component storage groove 21a side. In FIG. 2, a portion 30a on one end side of the flexible flat cable 30 is drawn in a state of being extended straight in the horizontal direction, but this may be to some extent depending on the shape of the upper and lower members in the lid 2. Of course, it is displaced up and down.

On the other hand, the rear end side 30b portion of the flexible flat cable 30 extends in an arc shape to the rear space 10c portion beyond the upper portion of the hinge unit 9, and then the back cover 19 and the outer wall 8a of the shoulder member 8 It extends straight through the gaps 10D and 10E between the two, and extends straight to the gap 10F between the cord reel 65 on the lower side and the outer case 7. The straight portion extending downward is indicated by reference numeral 30c.

The straight portion 30c is surely folded back in two at the gap 10F portion between the cord reel 65 and the outer case 7 described above to form a V-shaped folded-back portion 30d, and the slightly short folded-back piece 30e portion is formed. In a state of being curved in a gentle arc shape convex upward, the upper end side edge portion 61a of the control board cover 61 is passed through, and the tip end side 30f portion is slightly curved toward the lower side to the tip end. The connector portion (not shown) is connected to the connector 17 on the upper end side of the control board 60.

As a result, as shown in FIG. 4, the flexible flat cable 30 is transferred from the connector 16 portion (gap 10A portion) at the lower portion of the electrical component storage groove 21a in the lid body 2 to the lower portion of the steam cap storage groove 21b as shown in FIG. Passing through (gap 10B portion), the rice cooker main body 1 enters the rice cooker main body 1 through the gap 10c portion between the hinge unit 9 (the back plate 19 thereof) of the rice cooker main body 1 and the outer wall of the shoulder member 8, and then the control board cover 61 and the outside. It reaches the gap 10E between the case 7 and the gap 10F between the cord reel 65 and the outer case 7, and is surely folded back in two at the gap 10F between the cord reel 65 and the outer case 7 to form a V shape. The shape of the folded-back portion 30d is formed, and the folded-back piece 30e portion of the folded-back portion 30d is bent upward into a gentle arc shape that is convex upward, and the upper portion of the upper end side edge portion 61a of the control board cover 61 is formed. As you can see, the 30f portion on the tip end side is bent toward the lower side and connected to the connector 17 on the control board 60 side.

In this case, the flexible flat cable 30 (30a) in the lid 2 is basically arranged using the gaps 10A and 10B of the upper and lower members, but is simply arranged in the gaps 10A and 10B. If this is done, the cable may move in the gap when the lid 2 is opened and closed, and the brittle member may be damaged or the cable itself may be damaged. Therefore, for example, as shown in FIGS. 2 and 3, at least the front steam cap storage groove 21b pulled out to the rice cooker main body 1 side is attached with tape 35 to the bottom of the steam cap storage groove 21b. It is firmly fixed. As a result, slack in the lid 2 and interference with other members do not occur.

Therefore, according to such a configuration, the movement of each part of the flexible flat cable 30 that occurs when the lid 2 is opened and closed is shown in FIG. 2. In the state shown in FIG. 4, when the lid 2 is opened from the same state as shown in FIG. 5 and conversely closed in the state shown in FIG. 2, (a) to (c) of FIG. As shown in (a), the lid 2 side simply follows the opening / closing direction of the lid 2 freely, and the straight portion 30c and the folded portion 30d portion are controlled as described in (b). The gap 10E behind the board cover 61 and the gap 10F between the cord reel 65 and the outer case 7 are simply moved up and down straight up and down, and the fold-back portion 30d is gently convex upward toward the control board 60. The folded-back piece 30e, which is bent into an arc shape, only moves up and down in the vertical direction on the folded-back side while maintaining a large bent state as shown in (c).

Therefore, the conventional local deformation that repeatedly stresses the wiring portion itself does not occur, the durability is greatly improved, and there is no risk of disconnection due to opening and closing of the lid 2.

As described above, the folded piece 30e bent in a gentle arc shape convex upward from the folded portion 30d toward the control board 60 side is in a large bent state as shown in FIG. 4 (c). The folded side goes up and down in the vertical direction. Therefore, it is preferable that the introduction port portion 15 of the folded piece 30e to the control board 60 side is formed in a predetermined wide space. Therefore, in the case of this embodiment, the introduction space 15 portion is made into a space having an effective deformation space up and down, and the folded piece 30e can be freely moved up and down.

In the case of a flexible flat cable, it can be used without any functional problem even if it is folded back in two as described above. Since it is more effective to improve the durability of the folded-back portion 30d portion if it does not spread to each other, it means that the portion is within the narrow gap 10F between the cord reel 65 and the outer case 7 as described above. But it is preferable. Therefore, it is also effective to join the folded-back portions 30d to each other with tape.

Further, the straight portion 30c following the folded-back portion 35 also serves to discharge the water generated on the lid 2 side from the bottom case 12 to the outside by utilizing the space on the back side of the cord reel 65.

Further, in the above embodiment, the case where the flexible flat cable (FFC) is adopted has been described, but the above-described configuration of the present invention includes various similar electrical wirings such as an FPC and a wire harness formed by etching. Needless to say, it can be applied in exactly the same way when a material is used.
