Therefore, it is possible to accurately and surely detect the boiling state where steam is actually generated with a simple configuration, and supply hot water “as much as you want when you want”. Although this type of electric kettle is widely sold today, there are still few published examples of specific applications, and the prior art cannot be shown in the literature.

本出願人による従来構成の電気ケトルの縦断面図を図１４に示した。
この電気ケトル１００は、本体ボディ１０３内の水を加熱する加熱機構１０１、当該加熱機構１０１を始動する始動スイッチ（加熱操作スイッチ１１５）を備えるとともに、加熱完了を検知して加熱機構１０１による加熱を停止する停止機構１１８を備えている。この電気ケトルでは、蒸気検知機構１１９を本体ボディ１０３の下部に設け、この蒸気検知機構１１９に蒸気を導く検知側蒸気路１４０を加熱操作スイッチ１１５の内側に設けている。さらに、電気ケトル１００は、上部側に開口を有する本体ボディ１０３と、本体ボディ１０３の当該開口を閉止する蓋体１０８とを備えて構成され、蓋体１０８が開口を閉止する閉止姿勢と、開口が開いた開放姿勢との間で、蓋体１０８が本体ボディ１０３に設けられる揺動軸周りに揺動可能に構成されている。
また、蓋体１０８には注口１０９及び蒸気口１１２を、本体ボディ１０３にはハンドル１１０を備えている。
さらに、従来、注口１０９の近傍に設けられた弁体１１３の開閉を行う給湯操作ボタン１１４は、電気ケトル１００の上部ほぼ中央に設けられ、加熱操作スイッチ１１５は、ハンドル１１０の上側に設けられていた。
この構造では、ハンドル１１０を握った状態で加熱開始操作を行うことは可能であるが、給湯時に、ハンドル１１０を保持したまま給湯操作ボタン１１４を、片手で操作することができない。そこで、従来、給湯操作ボタン１１４は開閉何れかの状態に択一的に操作できる開閉操作型とされており、給湯操作ボタン１１４を開状態した後ケトル本体を傾けたり、ケトル本体を傾けた状態で、もう片方の手で給湯操作ボタン１１４を開状態とする必要があり、操作性に改良の余地があった。
さらに、この種の電気ケトル１００にあっては、水の沸騰に要する時間が適切な時間に設定される必要があるが、蒸気検知機構１１９に到達する蒸気が流れる検知側蒸気路１４０との関係で、この沸騰時間を適切に設定する技術は確立されていなかった。 FIG. 14 is a longitudinal sectional view of a conventional electric kettle according to the present applicant.

In this structure, the heating start operation can be performed with the handle 110 held, but the hot water operation button 114 cannot be operated with one hand while holding the handle 110 during hot water supply. Therefore, conventionally, the hot water supply operation button 114 is an open / close operation type that can be operated selectively in either the open / close state. After the hot water supply operation button 114 is opened, the kettle body is tilted or the kettle body is tilted. Therefore, it is necessary to open the hot water supply operation button 114 with the other hand, and there is room for improvement in operability.
Furthermore, in this type of electric kettle 100, the time required for boiling of water needs to be set to an appropriate time, but the relationship with the detection-side steam path 140 through which the steam reaching the steam detection mechanism 119 flows. Thus, no technology has been established for appropriately setting the boiling time.

先にも説明したように、電源プレート２上にケトル本体３が載置された給電状態（給電姿勢）においては、給電機構４がケトル本体３内に嵌り込み、互いの電極が電気的に接続されて受電が可能となる。 As shown in FIGS. 3 and 4, the power receiving mechanism 17 is formed at the center side position of the kettle main body 3 by retreating from the bottom surface. The power receiving mechanism 17 also has an approximately cylindrical appearance. Yes. The power receiving mechanism 17 includes a center guide pin 17a, an inner diameter side annular electrode 17b provided concentrically with the center guide pin 17a, and an outer diameter side annular electrode 17c provided on the outer diameter side. These three electrodes 17a, 17b, and 17c are a pair of electrodes for power reception and an electrode for power reception posture detection.
As described above, in the power feeding state (power feeding posture) in which the kettle body 3 is placed on the power supply plate 2, the power feeding mechanism 4 is fitted into the kettle body 3 and the electrodes are electrically connected to each other. Power can be received.

図３に示すように、前記受電機構１７と前記加熱操作スイッチ１５とは、電気ケトル１において広く使用されている連動ユニット１８で連結されている。この連動ユニット１８の構成を説明すると、ケトル本体３側に受電機構１７を備えるとともに、この受電機構１７と一体に外周方向に延びる固定腕部１８ｂを備えたユニット本体１８ａと、その固定腕部１８ｂの上部側に設けられ、ユニット本体１８ａに対して上下方向に揺動自在な揺動腕部１８ｃとを備えて構成されている。 As shown in FIG. 3, the power receiving mechanism 17 and the heating operation switch 15 are connected by an interlocking unit 18 widely used in the electric kettle 1. The structure of the interlocking unit 18 will be described. The power receiving mechanism 17 is provided on the kettle main body 3 side, and the unit main body 18a including a fixed arm portion 18b extending integrally with the power receiving mechanism 17 in the outer peripheral direction, and the fixed arm portion 18b. Is provided with a swinging arm portion 18c that is swingable in the vertical direction with respect to the unit main body 18a.

前記固定腕部１８ｂの外周側端には、ケトル本体上部から導かれる蒸気検知具１９（具体的には蒸気感応板からなり、蒸気に感応して変形する）が備えられている。前記揺動腕部１８ｃの先端は、先に説明した加熱操作スイッチ１５が連結されている。
ケトル本体３に設けられる受電機構１７が、電源プレート２に設けられる給電機構４から電気の供給を受けられる状態で、且つ、蒸気検知具１９が蒸気を検知していない状態で、加熱操作スイッチ１５は、実線で示すその待機姿勢に保たれる。加熱操作スイッチ１５が押し下げ操作されると、前記揺動腕部１８ｃは下方に揺動され加熱維持姿勢に維持されるとともに、加熱機構１６への給電を行う。従って、水の加熱が開始される。
加熱によりケトル本体３内の水が沸騰すると、その湯から発生する蒸気がケトル本体内側部に設けられる検知側蒸気路４０を介して蒸気検知具１９に到達し、この蒸気検知具１９の蒸気検知に伴って、下方に揺動姿勢保持されていた前記揺動腕部１８ｃの姿勢保持が解除され、上方に揺動復帰されるとともに、加熱機構１６への給電が停止される。同時に、加熱操作スイッチ１５は、加熱維持姿勢から待機姿勢に復帰する。 A steam detector 19 (specifically, a steam sensitive plate that deforms in response to steam) is provided at the outer peripheral side end of the fixed arm 18b. The above-described heating operation switch 15 is connected to the tip of the swing arm portion 18c.
The heating operation switch 15 is in a state in which the power receiving mechanism 17 provided in the kettle body 3 is supplied with electricity from the power feeding mechanism 4 provided in the power supply plate 2 and the steam detector 19 is not detecting steam. Is kept in its standby position shown by the solid line. When the heating operation switch 15 is pushed down, the swing arm portion 18c swings downward and is maintained in the heating maintenance posture, and supplies power to the heating mechanism 16. Therefore, heating of water is started.
When the water in the kettle body 3 boils by heating, the steam generated from the hot water reaches the steam detector 19 via the detection-side steam path 40 provided in the inner part of the kettle body, and the steam detection of the steam detector 19 Along with this, the posture holding of the swinging arm portion 18c held in the downward swinging posture is released, the swinging is returned upward, and the power supply to the heating mechanism 16 is stopped. At the same time, the heating operation switch 15 returns from the heating maintenance posture to the standby posture.

従って、連動ユニット１８は、受電機構１７と連動して、生成される湯から発生する蒸気を検知して、加熱機構１６による加熱を停止する停止機構として働く。 Therefore, the interlocking unit 18 operates as a stop mechanism that detects steam generated from the generated hot water in conjunction with the power receiving mechanism 17 and stops heating by the heating mechanism 16.

蒸気口１２は、転倒止水弁２８（錐体収納空間２８ｂ）と給湯操作ボタン１４との間に設けられている。 As shown in FIG. 5, in the electric kettle 1 according to the present application, as the overturn stop water valve 28, a pair of fall stop water valves 28 having different water stop speeds are linearly formed between the spout 9 and the hot water supply operation button 14. Are arranged side by side. Further, as can be seen from FIG. 6, a moving member 25 is provided between the valve mechanism 20 and the hot water supply operation button 14, which is movable in the longitudinal direction of the main body according to the position of the hot water operation button 14. A bifurcated portion 25b is provided on the hot water operation button 14 side of the moving member 25, and the bifurcated portion 25b can be brought into contact with the hot water supply operation button 14 through the side portions of the overturn stop water valve 28 and the common steam chamber 29a. .
The steam port 12 is provided between the overturn stop water valve 28 (cone housing space 28 b) and the hot water supply operation button 14.

先に説明した上下の挟持部材８４ａ及び８４ｂにより、主に二股部２５ｂを上下から挟む構成が採用されている。そして、図１１に示すように、二股部２５ｂを上下の挟持部材８４ａ及び８４ｂにより、その上下左右から挟むことにより、移動部材２５にがたが発生するのを極力、回避している。 A configuration is adopted in which the bifurcated portion 25b is mainly sandwiched from above and below by the above-described upper and lower clamping members 84a and 84b. Then, as shown in FIG. 11, rattling of the moving member 25 is avoided as much as possible by sandwiching the bifurcated portion 25b between the upper and lower clamping members 84a and 84b.

さらに、図９、図１０に示すように、蓋本体８０と下側の挟持部材８４ｂとの間には、一対の転倒止水弁２８（錐体収納空間２８ｂ）を囲む形態で、蓋本体８０側に長円形の補助リブ８５が備えられ、その外周に止水弁用パッキン８６が備えられている。この止水弁用パッキン８６は、補助リブ８５より大きく形成されており、止水弁用パッキン８６が補助リブ８５に当接して強制変形されることはない。 Furthermore, as shown in FIGS. 9 and 10, the lid body 80 is configured so as to surround the pair of fall-off water valves 28 (cone housing space 28 b) between the lid body 80 and the lower clamping member 84 b. An oblong auxiliary rib 85 is provided on the side, and a water stop valve packing 86 is provided on the outer periphery thereof. The water stop valve packing 86 is formed larger than the auxiliary rib 85, and the water stop valve packing 86 does not contact the auxiliary rib 85 and is not forcibly deformed.

さて、図６に示すように、前記給湯操作ボタン１４は、移動部材２５側が二股に構成されている。この二股部位１４ａは、蓋本体８０に設けられた一対の侵入孔８０ａに侵入するが、この侵入孔８０ａは上下方向に長い、長孔として構成されている。このように長孔として構成している理由は、図７、図８に対比して示すように、蓋体８の開閉操作に拘らず、最大押し込み時でも、給湯操作ボタン１４の二股部位１４ａが、蓋本体８０と干渉するのを避けるためである。 Now, as shown in FIG. 6, the hot water supply operation button 14 is configured to be bifurcated on the moving member 25 side. The bifurcated portion 14a enters a pair of intrusion holes 80a provided in the lid body 80. The intrusion hole 80a is configured as a long hole that is long in the vertical direction. The reason why the long hole is configured as described above is that, as shown in FIGS. 7 and 8, the bifurcated portion 14a of the hot water supply operation button 14 is not limited to the opening / closing operation of the lid body 8 even when the lid 8 is fully pushed. This is to avoid interference with the lid body 80.
