The present invention relates to an electric kettle having a spout and a steam port in the lid and a handle in the main body.

この種の電気ケトルは、「欲しい時に、欲しい分だけ」というキャッチフレーズのもとに、現在販売されているものであり、電源プレートと、その電源プレートから電力の供給を受けて、ケトル本体に注がれた水を加熱する加熱機構を備えている。加熱により得られる湯は、ケトル本体を電源プレートから持ち上げ、ケトル本体を傾けることで注口から取り出すことができる。 This type of electric kettle is currently being sold under the catchphrase of “when you want, just as much as you want”, and it receives power from the power plate and the power plate to the kettle body. A heating mechanism is provided for heating the water that has been removed. Hot water obtained by heating can be taken out from the spout by lifting the kettle body from the power supply plate and tilting the kettle body.

加熱完了の検知に関しては、例えば、湯から発生する蒸気を検知部に導き、その蒸気を検知することで、加熱を停止する構成とされている。従って、実際に蒸気が発生している沸騰状態を、簡易な構成で、正確かつ確実に検知して、「欲しい時に、欲しい分だけ」湯を供給できる。この種の電気ケトルは、今日、一般に広く販売されているものではあるが、具体的な出願例は、未だ公開例は少なく、その先行技術を文献で示すことはできない。 Regarding the detection of the completion of heating, for example, the steam generated from the hot water is guided to a detection unit, and the steam is detected to stop the heating.

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 arm portion 18b A swing arm portion 18c provided on the upper side and swingable in the vertical direction with respect to the unit main body 18a is provided.

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側部に設けられる蒸気路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 steam path 40 provided on the side of the kettle body, and accompanying the steam detection of the steam detector 19 Then, the posture holding of the swing arm portion 18c held downward is released, the swing swing 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.

〔蓋開閉〕
以下、図６から図１０に基づいて、蓋体８の開閉のための蓋体開閉操作部１１まわりの構成に関して説明する。
図６は、移動部材２５と蓋体開閉操作部１１の位置関係を示す図であり、図７は、蓋体開閉操作部１１が押入操作されて、蓋体８を揺動開操作可能な状態を示す図であり、図８は、給湯操作ボタン１４が押し込まれ、移動部材２５が注口９側へ移動した状態で、蓋体開閉操作部１１の押入操作ができない状態を説明する図面である。さらに、図９、図１０は、それぞれ蓋体開閉操作部１１まわりの構成を示す分解斜視図である。 [Open / close lid]
Hereinafter, a configuration around the lid opening / closing operation unit 11 for opening and closing the lid 8 will be described with reference to FIGS.
FIG. 6 is a diagram showing the positional relationship between the moving member 25 and the lid opening / closing operation unit 11. FIG. 7 shows a state in which the lid opening / closing operation unit 11 is pushed in and the lid 8 can be swing-opened. FIG. 8 is a diagram for explaining a state in which the lid body opening / closing operation unit 11 cannot be pushed in when the hot water operation button 14 is pushed in and the moving member 25 is moved toward the spout 9 side. . 9 and 10 are exploded perspective views showing the configuration around the lid opening / closing operation unit 11, respectively.

蓋体８の開閉は、図７に示すように、蓋体開閉操作部１１が押入操作されることで、本体ボディ７との係合部材９０の係合が外れることで可能となる。即ち、蓋体開閉操作部１１の前側（注口側）が押入操作されることで、その揺動軸１１ａ周りに揺動し、係合部材９０の係合作用部９１が後方に移動することで、係合が外れる。
但し、図８に示すように、給湯操作ボタン１４が押し込まれ、移動部材２５が注口９側へ移動した状態では、蓋体開閉操作部１１の揺動が移動部材２５の先端で阻止され、実質的な押入操作を行うことができないように構成してもよい。 As shown in FIG. 7, the lid body 8 can be opened and closed by releasing the engagement of the engagement member 90 with the main body body 7 by pushing the lid body opening / closing operation section 11. That is, when the front side (the spout side) of the lid opening / closing operation part 11 is pushed in, it swings around the swinging shaft 11a, and the engaging action part 91 of the engaging member 90 moves rearward. Then the engagement is released.
However, as shown in FIG. 8, in the state where the hot water supply operation button 14 is pushed in and the moving member 25 is moved to the spout 9 side, the swing of the lid opening / closing operation unit 11 is prevented by the tip of the moving member 25, You may comprise so that substantial push-in operation cannot be performed.

これら図からも判明するように、係合作用部９１は、揺動軸１１ａより前側で、かつ、揺動軸１１ａより下側に配置されている。従って、電気ケトル１の上部がスッキリとした構成となるとともに、蓋体８の開閉を良好に行える。
さらに、係合部材９０に対しては、この係合部材９０を係合側に付勢する係合部材付勢機構９２が設けられているが、図９等からも判明するように、前記係合作用部９１は、上面視、注口９の位置を挟む形態で一対設けられており、それらの後方に同軸（同一直線上）に、前記係合部材付勢機構９２を成す一対のスプリング９２ａが設けられている。結果、係合部材９０が前後方向に均等に付勢できる。同時に、前記蓋体開閉操作部１１の係合部材９０に対する作用部位１１ｂも、前記係合作用部９１に対応して一対設けられるとともに、上面視、同一直線上に重なる位置とされている。結果、係合部材９０のスムーズな動作が可能である。
この係合部材９０は、上面視では、概略、井桁状に構成されており、移動に伴ってゆがみ等が発生しにくい構成が採用されている。 As can be seen from these drawings, the engaging action portion 91 is disposed on the front side of the swing shaft 11a and on the lower side of the swing shaft 11a. Therefore, the upper portion of the electric kettle 1 has a clean structure, and the lid 8 can be opened and closed satisfactorily.
Further, an engagement member urging mechanism 92 that urges the engagement member 90 toward the engagement side is provided for the engagement member 90. As can be seen from FIG. A pair of the action portions 91 are provided in a form sandwiching the position of the spout 9 when viewed from above, and a pair of springs 92a forming the engaging member urging mechanism 92 coaxially (colinearly) behind them. Is provided. As a result, the engaging member 90 can be equally biased in the front-rear direction. At the same time, a pair of action portions 11b of the lid opening / closing operation portion 11 with respect to the engagement member 90 are also provided corresponding to the engagement action portion 91 and overlapped on the same straight line when viewed from above. As a result, the engaging member 90 can be smoothly operated.
The engagement member 90 is generally configured in a cross beam shape when viewed from the top, and a configuration in which distortion or the like hardly occurs with movement is employed.

〔残水量の低減〕
本願に係る電気ケトル１では、弁機構２０を極力、注口９側に寄せることで、給湯開始の迅速化及び残水量の低減が図られているが、蓋本体の形状構成に関しても工夫が成されている。即ち、図５、図６に示すように、弁機構２０のハンドル１０側の下面には、弁機構２０に近づくに従って内容器７０側、即ち、電気ケトル１において下側となる傾斜面２８が備えられている。このような傾斜面２８を設けることでも、水切れを良好なものとし、残水量を減らすことができる。 [Reduction of remaining water]
In the electric kettle 1 according to the present application, the valve mechanism 20 is moved to the spout 9 side as much as possible to speed up the start of hot water supply and reduce the amount of remaining water. Has been. That is, as shown in FIGS. 5 and 6, the lower surface of the valve mechanism 20 on the handle 10 side is provided with an inclined surface 28 that becomes the inner container 70 side, that is, the lower side in the electric kettle 1 as it approaches the valve mechanism 20. It has been. Providing such an inclined surface 28 can also improve water drainage and reduce the amount of residual water.

〔注口下部の集水〕
以下、図５、図１１、図１２に基づいて、蓋体８の開閉のための蓋体開閉操作部１１まわりの構成に関して説明する。
湯沸し前に使用者が水を内容器７０に入れた際、内容器の７０のフランジ付近（容器用パッキン８２の外側）に水が残ったままとなることがある。湯沸し後、これに気づかず、ケトル本体３を給湯のため傾けてしまうと、蓋体８と本体ボディ７との隙間から、湯が漏れることがある。さらに、容器パッキン８２が劣化すると、給湯時に、同じ箇所から湯が漏れる可能性がある。 [Catchment at the bottom of the spout]
Hereinafter, a configuration around the lid opening / closing operation unit 11 for opening and closing the lid 8 will be described with reference to FIGS. 5, 11, and 12.
When the user puts water into the inner container 70 before boiling, the water may remain near the flange of the inner container 70 (outside the container packing 82). If the kettle body 3 is tilted for hot water supply without being noticed after boiling, the hot water may leak from the gap between the lid body 8 and the body body 7. Furthermore, if the container packing 82 deteriorates, hot water may leak from the same location during hot water supply.

そこで、本願に係る電気ケトル１では、注口９の下部の本体ボディ７の形状に関しても一定の工夫がされている。この部位は、注口９の下部に位置し、本体ボディ７の外郭よりは内側に位置する部位である。先にも示したように、本願に係る電気ケトル１は、内容器７０を備えた構成を採用しており、その上面外径部にフランジが備えられている。さらに、このフランジを、本体ボディ７に設けられた支持部７ａより支持する構造が採用されている。従って、この構造では、前記支持部７ａの上側に容器用パッキン８２に対して外部となる空間７２が存在する。本願においては、この空間７２に残留した水が問題なのであるが、この水を注口９の下部に集める構成を採用している。 Therefore, in the electric kettle 1 according to the present application, a certain contrivance is made with respect to the shape of the main body body 7 below the spout 9. This part is located in the lower part of the spout 9 and is located inside the outer body of the main body 7. As previously indicated, the electric kettle 1 according to the present application employs a configuration including the inner container 70, and a flange is provided on the outer surface of the upper surface thereof. Furthermore, the structure which supports this flange from the support part 7a provided in the main body body 7 is employ | adopted. Accordingly, in this structure, a space 72 that is external to the container packing 82 exists above the support portion 7a. In the present application, although water remaining in the space 72 is a problem, a configuration is adopted in which this water is collected at the bottom of the spout 9.

そこで、本願に係る電気ケトル１では、本体ボディ７の注口９の下部域に、図１１に示す傾斜凹部７３を形成している。この傾斜凹部７３の上面視形状は、注口９センタに近接する程、傾斜凹部の先端が注口側（先端側）に出るように構成されている。図１１に示す例では、上面視形状が円弧状に張り出した例であり、図１２に示す例は、注口９の幅方向のセンタにおいて、注口９の下部で最も張り出した受け口形状とする例である。この傾斜凹部の７３の両側に、先に説明した係合作用部９１が係合する被係合部７４が一対設けられている。
このように、傾斜凹部７３を注口９下部の本体ボディ７部位に設けることで、本体ボディ７を傾けた状態で、フランジ上の湯を、注口下部（幅方向のセンタ）に集めて、外部へ放出することができる。このような傾斜凹部としては、円弧状、受け口状に構成する他、上面視幅方向センタ振り分けの直線状辺を備えた構成としても良い。 Therefore, in the electric kettle 1 according to the present application, the inclined recess 73 shown in FIG. 11 is formed in the lower region of the spout 9 of the main body 7. The shape of the inclined concave portion 73 as viewed from above is configured such that the tip of the inclined concave portion protrudes toward the spout side (the front end side) as it approaches the center of the spout 9. In the example shown in FIG. 11, the shape of the top view projects in an arc shape, and the example shown in FIG. 12 has a receptacle shape that projects most at the lower part of the spout 9 at the center in the width direction of the spout 9. It is an example. On both sides of the inclined recess 73, a pair of engaged portions 74 with which the engaging action portion 91 described above is engaged are provided.
Thus, by providing the inclined recess 73 in the body body 7 part below the spout 9, hot water on the flange is gathered at the spout lower part (center in the width direction) while the main body body 7 is tilted to the outside. Can be released. Such an inclined concave portion may be configured in a circular arc shape or a receptacle shape, or may have a linear side that is centered in the width direction in the top view.

〔別実施形態〕
（イ）これまで説明してきた実施形態では、沸騰状態を検知して加熱完了状態を検知するものとしたが、湯水の温度を直に検知したり、予測検知したりして、加熱完了を検知し、停止機構を働かせるものとしてもよい。
(ロ) 上記の実施形態においては、弁体に補強リブを設けた構成を示したが、材料選択、他の部位の寸法選択等により、弁体の剛性が充分確保できるのであれば、この補強リブを設ける必要は必ずしもない。また、案内孔に設けられる凹部、中心移動軸に設けられる
凸部に関しても、回り止めが確保できれば同様である。 [Another embodiment]
(B) In the embodiments described so far, the boiling completion state is detected and the heating completion state is detected. However, the completion of heating is detected by directly detecting the temperature of hot water or predicting it. However, a stop mechanism may be used.
(B) In the above embodiment, the structure in which the valve body is provided with the reinforcing rib is shown. However, if the rigidity of the valve body can be sufficiently secured by selecting the material, selecting the dimensions of other parts, etc., this reinforcement It is not always necessary to provide ribs. Further, the same applies to the concave portion provided in the guide hole and the convex portion provided in the central movement shaft as long as the rotation stopper can be secured.

以上説明したように、ケトル本体を傾けて注湯する給湯時に、片手で容易に操作を行うことができ、さらに、弁機構を注口側に寄せたので、迅速に給湯が始まる電気ケトルを得ることができた。 As described above, when supplying hot water by tilting the kettle body, it can be easily operated with one hand, and since the valve mechanism is moved to the spout side, an electric kettle that starts hot water supply quickly is obtained. I was able to.
