In addition to being a barrier, there are flammable members such as cockroaches in the vicinity of each connector, and when the flammable member ignites, a flame retardant resin or non-flammable member that covers each connector is a rice cooker A barrier against expansion fire of combustible members firing into 1 internal, it is possible to prevent failure and burning of the rice cooker main body 1. Moreover, even if the connection part 27 becomes high temperature, each connector melt | dissolves, and the case where it remove | deviates from the connection part 27 or the case where it hangs down occurs, the movement range of the connection part 27 can be controlled with the terminal cover 26, and the outline of the rice cooker main body 1 The body 2 molded with the resin member forming the heat can cut off the heat from the connecting portion 27 and the connecting portion 27 is prevented from directly contacting the body 2 molded with the resin member forming the outline of the rice cooker body 1. it can. In addition, since each connector is enclosed in a narrow space with a flame retardant member, there is a combustible member such as a cockroach near each connector housing, and self-extinguishment is possible even if ignition occurs from the combustible member. There is a high possibility of doing.
同様に、底誘導加熱コイル６と加熱制御基板２１の接続部２７であるターミナル部も、炊飯器本体１の前方向をターミナルカバー２６で、後方向を加熱制御基板２１と加熱制御基板用基板ベース２２で、左右方向をターミナルカバー２６とヒートシンク２４で、上方向を操作制御基板２１と操作制御基板用基板ベース２２で、下方向をターミナルカバー２６で全ての方向を難燃性部材で覆うことを実現し、ターミナル部２８が高温になった際、ターミナル部２８を覆う難燃性樹脂又は不燃部材が炊飯器本体の外郭を形成する樹脂部材で成形されたボディ２への熱の供給に対する障壁となると共に、ターミナル部２８近傍にゴキブリ等の可燃性部材が存在し、その可燃性部材が発火した際もターミナル部２８を覆う難燃性樹脂又は不燃部材が炊飯器本体１内部への可燃部材発火の拡大延焼に対する障壁となり、炊飯器本体１の故障及び燃焼を防止することができる。また、接続部２７が高温になり、ターミナル部を２８を支持する加熱制御基板用基板ベース２２が溶解し、接続部２７から外れるもしくは垂れる事例が発生しても、ターミナルカバー２６により接続部２
７の移動範囲を規制でき、炊飯器本体１の外郭を形成する樹脂部材で成形されたボディ２に接続部２７からの熱を遮断できると共に接続部２７が炊飯器本体１の外郭を形成する樹脂部材で成形されたボディ２に直接接触することを防止できる。また、ターミナル部２８を難燃性部材で狭い空間に囲む構成をとっているため、ターミナル部２８近傍にゴキブリ等の可燃性部材が存在し、その可燃性部材から発火が生じたとしても自己消火をする可能性が高い。
Similarly, the terminal part which is the connection part 27 of the bottom induction heating coil 6 and the heating control board 21 also has the terminal cover 26 in the front direction of the rice cooker body 1 and the heating control board 21 and the board base for the heating control board in the rear direction. 22, the left and right directions are covered with the terminal cover 26 and the heat sink 24, the upper direction is covered with the operation control board 21 and the operation control board substrate base 22, and the lower direction is covered with the terminal cover 26 and all directions are covered with a flame-retardant member. Realizing and when the terminal part 28 becomes high temperature, the flame retardant resin or the non-combustible member covering the terminal part 28 is a barrier against the supply of heat to the body 2 formed of the resin member that forms the outline of the rice cooker body; In addition, there is a combustible member such as a cockroach in the vicinity of the terminal portion 28, and even when the combustible member ignites, a flame-retardant resin or non-combustible member that covers the terminal portion 28 is cooked. A barrier against expansion fire combustible members firing into vessel body 1 inside, and hence it is possible to prevent failure and burning of the rice cooker main body 1. Even if the connection part 27 becomes hot and the heating control board substrate base 22 supporting the terminal part 28 melts, and the case where the connection part 27 comes off from the connection part 27 or hangs down occurs, the connection part 2 is connected by the terminal cover 26.

Further, since the terminal portion 28 is surrounded by a flame retardant member in a narrow space, there is a combustible member such as a cockroach in the vicinity of the terminal portion 28, and even if ignition occurs from the combustible member, self-extinguishing is possible. There is a high possibility of doing.
また、図４の（ａ）、（ｂ）に示すように、ターミナルカバー２６の方端を各接続部２７から離れたヒートシンク２４で保持することができ、各接続部２７が高温になった際も接続部からの熱の影響を受ける事がなく、ターミナルカバー２６の位置を規制することができる。同時にターミナルカバー２６の両端にヒートシンク２４を挟み込む構成により、冷却ファン２５から炊飯器本体１内部に供給される風の向きも変更することができ、炊飯器本体１内部の冷却性能も向上することができる。また、底センサー８に流れる風の向きもターミナルカバー２６の形状を変更することで調整でき、底センサー８の検知精度の向上を実現することができ、このことにより、炊飯性能の向上も実現することができる。ターミナルカバー２６の配置位置、形状は不燃化構成を実現し得る物であれば、求める効果により臨機応変に変更することで合理的な設計を実現することができる。 Further, as shown in FIGS. 4A and 4B, the end of the terminal cover 26 can be held by the heat sink 24 separated from each connecting portion 27, and when each connecting portion 27 becomes hot. Also, the position of the terminal cover 26 can be regulated without being affected by the heat from the connecting portion. At the same time, the structure in which the heat sink 24 is sandwiched between both ends of the terminal cover 26 can change the direction of the wind supplied from the cooling fan 25 to the inside of the rice cooker body 1, and the cooling performance inside the rice cooker body 1 can be improved. it can. In addition, the direction of the wind flowing through the bottom sensor 8 can be adjusted by changing the shape of the terminal cover 26, and the detection accuracy of the bottom sensor 8 can be improved, thereby improving the rice cooking performance. be able to. As long as the arrangement position and shape of the terminal cover 26 can realize a non-combustible configuration, a rational design can be realized by changing the terminal cover 26 according to the desired effect.
上述の本発明の実施の形態１の炊飯器の構成は、複数個の接続部２７を１つの難燃性樹脂及び不燃性部材により形成される１つ空間に収納するという合理的な構成であり、各接続部毎に難燃性樹脂もしくは不燃部材で覆う構成を設ける必要がなく、構成部品の増加や設計の複雑化という問題を未然に防止することができ、その結果として炊飯器のコンパクト化にも寄与することができる。上記記載の接続部２７以外に多数接続部２７を有する炊飯器においても、同様に１つの収納部に収めるのが好ましいが、構成上、１つの箇所に収納不可能な際は別途その他の箇所に同様な構成を有することで上記構成と同様な効果が得られる。 The configuration of the rice cooker according to Embodiment 1 of the present invention described above is a rational configuration in which a plurality of connection portions 27 are accommodated in one space formed by one flame-retardant resin and a non-flammable member. In addition, it is not necessary to provide a structure to cover each connection part with a flame-retardant resin or non-combustible material, and it is possible to prevent problems such as an increase in the number of components and complicated design, resulting in a compact rice cooker. Can also contribute. In the rice cooker having a large number of connection portions 27 other than the connection portion 27 described above, it is preferable that the rice cooker is similarly stored in one storage portion. However, when it cannot be stored in one location, it can be stored separately in other locations. By having the same configuration, the same effect as the above configuration can be obtained.
また、製品組立時においてターミナルカバー２６を装着する工程は、製品の組立上、必然的に全ての配線処理終了後に行われる。そのため、接続部２７を含めた配線を一括してターミナルカバー２６内部に収納することができるので、組立時の配線バラケを減少することができ、ターミナルカバー２６装着後のボディ２装着時にボディ２と上枠３の間での配線噛み込み等の不具合も改善でき、組立性の向上を実現することができる。更には、複雑な配線処理をする必要がないため、配線処理が容易となり組立工数の削減も実現することができる。 Further, the step of attaching the terminal cover 26 at the time of product assembly is inevitably performed after completion of all the wiring processes in terms of product assembly. Therefore, since the wiring including the connecting portion 27 can be collectively stored in the terminal cover 26, the wiring variation at the time of assembly can be reduced, and when the body 2 is mounted after the terminal cover 26 is mounted, Problems such as wiring biting between the upper frames 3 can be improved, and an improvement in assemblability can be realized. Furthermore, since it is not necessary to perform complicated wiring processing, wiring processing is facilitated and the number of assembly steps can be reduced.
また、製品組立後、市場に出る過程もしくは市場にて、移送時の振動、持ち運び時の製品落下等の様々な要因で製品内部の配線がバラケる要因が存在するが、それならの事象が発生してもターミナルカバー２６により配線部の位置規制が確実にできていることから、前記不具合で配線がバラケる可能性が減少するため、設計どおりの配線を出荷後にも実現でき、より安全性の高い製品を市場に提供することができる。 In addition, there are factors that cause the wiring inside the product to be scattered due to various factors such as vibration during transportation and product dropping during transportation after the product is assembled, or in the market. However, since the position of the wiring portion can be surely regulated by the terminal cover 26, the possibility of the wiring being scattered due to the above-mentioned defect is reduced, so that the wiring as designed can be realized even after shipment, and the safety is higher. Products can be offered to the market.
