[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure for a rice cooker .

[0002]

2. Description of the Related Art Lead wires are attached to the main electric components of a rice cooker such as a heater, a sensor, a control board, and a code reel, and the lead wires are wired between the electric components and connected to each other. It is way.

[0003]

As described above, the conventional
In a rice cooker , since the lead wires of each electric component are individually routed and wired, the wiring work is complicated, and it is difficult to automate without relying exclusively on manual work.

[0004] Therefore, an object of the present invention is to provide a wiring structure using a wiring board, which enables the assembling operation of a rice cooker to be automated.

[0005]

In order to achieve the above object, the present invention provides a sub-wiring board for each of a plurality of component blocks and a main wiring board corresponding to each of the sub-wiring boards. The main wiring board has a plurality of connectors connected to the connector terminals of the sub-wiring board, and each of the connectors includes a connector terminal electrically connected to an electric component of each component block by a required internal wiring. In a wiring structure of a rice cooker having required internal wiring for connecting to a power supply terminal,
The board is a control board provided in front of the outer body of the rice cooker
And a relay wiring board provided at the rear of the exterior body
The control board is provided at a front portion of the exterior body.
The above-mentioned relay wiring board is inserted into the
Hinge pin on the outer lid
It is rotatably connected and installed at the rear of the above exterior body.
It is configured to be inserted into a closed storage room .

[0006]

When assembling a rice cooker having the above-mentioned wiring structure, the wiring between the electric component of each component block and the sub-wiring board, and the internal wiring of the sub-wiring board and the main wiring board must be processed in another process in advance. In the assembly process, while attaching the sub-wiring board and the main wiring board,
The connector terminal of each sub-wiring board is connected to the connector of the main wiring board, and the connector of the main wiring board is connected to the power supply terminal.

DETAILED DESCRIPTION FIG 1 shows a cooking Jia chromatography as Example. In this rice cooker, a pot 2 is housed in an exterior body 1 so as to be able to be taken in and out freely. .

A heating plate 7 is mounted on the bottom heat shield plate 6 inside the exterior body 1 and a heater 8 is cast inside the heating plate 7.

An inner shell 9 is mounted on the outer peripheral edge of the heating plate 7, and the upper end of the inner shell 9 has a side heat shield plate 1 surrounding the inner shell 9.
1 is attached.

A control board case 1 is provided at the front of the exterior body 1.
Two storage chambers 13 are provided, and the control board case 12 is inserted into the storage chamber 13 from the upper end opening as shown in FIG. The control board case 12 has a control board 14 provided therein. The control board 14 comprises a microcomputer and other control component blocks and a printed wiring circuit for electrically connecting the components to each other, and constitutes a sub-wiring board referred to in the claims.

The control board 14 has a connector terminal 15, and the connector terminal 15 is provided with a screw 16 at the bottom of the exterior body 1.
18 of the main wiring board 17 attached by
Be inserted into.

At the rear part of the exterior body 1, a storage room 21 for the relay wiring board 19 is provided. As shown in FIG. 3, the relay wiring board 19 is rotatably connected to the outer lid 4 by the hinge pin 3, and is connected to each component constituting a component block such as a lid heater 22 and a sensor of the outer lid 4. The connected lead wire 23 is connected to the connector terminal 25 of the relay wiring board 19 via the hinge portion. This relay wiring board 19
This also constitutes one sub-wiring board, and its connector terminal 25 is connected to the connector 26 of the main wiring board 17. Note that this relay wiring board 19 is
Is fixed to the exterior body 1.

Around the inner body 9, the lead wires 3 connected to the parts constituting the part block, such as the body heater 28, the side sensor 29, and the temperature fuse 31, are provided.
2 is connected to the inner body wiring board 33 fixed to the inner body 9.
The inner wiring board 33 also constitutes one sub-wiring board, and its connector terminals 34 are connected to the connectors 35 of the main wiring board 17.

Further, both ends of the heater 8 cast into the heating plate 7 are directly connected to the connector terminals 36, and the connector terminals 36 are connected to the connectors 37 of the main wiring board 17. In this case, the heating plate 7 itself constitutes one sub-wiring board.

Further, a screw 39 is provided in the recess 38 on the lower surface of the bottom body 5.
Thus, the code reel 41 is attached (see FIG. 4).
The cord reel 41 is provided with two connector terminals 42 connected to the cords inside the reel.
Is inserted upward into the connector 43 of the main wiring board 17 from the lower surface thereof to perform connection.

The rice cooker of the embodiment is as described above, and the above-mentioned respective sub-wiring boards are supplied to the assembling process in a state where the assembling is completed in advance. That is, the control board 14 is manufactured in advance and assembled to the control board case 12. Further, the relay wiring board 19 is also attached to the outer lid 4,
In addition, the wiring of the lead wire 23 has been completed. The same applies to the inner barrel 9, the heating plate 7, and the code reel 41.

The main wiring board 17 is also connected to the lead wires 44.
Thus, internal wiring such as printed wiring or lead wire is performed between the connectors 18, 26, 35, 37, and 43 in advance, and connected to the connector terminal 42 of the code reel 41, which is a power supply terminal.

In the assembling process, the outer heat sink 1 is turned upside down, the side heat shield 11, the inner shell 9, the heating plate 7, and the bottom heat shield 6 are assembled. Fix it. At this time, the connector terminals 34 of the inner body wiring board 33 and the connector terminals 36 of the heating plate 7 are connected to the connectors 35 and 37 of the main wiring board 17, respectively.

Further, the bottom body 5 is attached to the exterior body 1, and at this time, the connector terminals 42 of the code reel 41 are connected to the connectors 43 of the main wiring board 17.

Next, after the exterior body 1 is inverted and erected, the control board case 12 is moved to the storage room 13 at the front of the exterior body 1.
The connector terminal 15 of the control board 14 is connected to the connector 18 of the main wiring board 17. Also, the relay wiring board 19 integrated with the outer lid 4 is inserted into the rear storage room 21,
The connector terminal 25 is connected to the connector 26 of the main wiring board 17. At this time, the outer lid 4 is put on the upper surface of the exterior body 1. Also, the relay wiring board 19 is fixed to the exterior body 1 with the screws 27, and the assembly is completed.

[0021]

As described above, according to the present invention, since the sub-wiring board is provided for each of several component blocks, the internal wiring between each component and the sub-wiring board can be completed in another process other than the assembling process. I can put it.

Since each sub-wiring board has connector terminals, it is only necessary to connect each connector terminal to the connector of the main wiring board in the assembling process. No need to do. Therefore, the work of the assembling process is significantly simplified, and a robot can be used.
