Description

本発明は、貯留している湯水を加熱する加熱手段と、
加熱停止位置と加熱作動位置とに移動操作自在で且つ前記加熱作動位置から前記加熱停止位置に復帰付勢された操作具を備えて、その操作具が前記加熱作動位置に位置する状態で前記加熱手段を加熱作動させ且つ前記操作具が前記加熱停止位置に位置する状態で前記加熱手段の加熱作動を停止させるように構成されたスイッチ手段とが設けられた電気ケトルに関する。 The present invention comprises a heating means for heating the stored hot water,
An operating tool that can be moved and operated between a heating stop position and a heating operation position and that is biased back to the heating stop position from the heating operation position is provided, and the heating tool is positioned in the heating operation position. The present invention relates to an electric kettle provided with switch means configured to heat the means and stop the heating operation of the heating means in a state where the operation tool is located at the heating stop position.

かかる電気ケトルは、「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、操作具が加熱作動位置に位置されると、加熱手段が加熱作動して貯留されている湯水が加熱され、操作具が加熱停止位置に位置されると、加熱手段の加熱作動が停止するように構成されているものである。
このような電気ケトルは、今日、一般に広く販売されているものであるが、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にて示すことができない。 Such an electric kettle is currently sold under the catch phrase “when you want, just as much as you want.” When the operation tool is located at the heating operation position, the heating means is heated and stored. When the hot water being heated is heated and the operation tool is positioned at the heating stop position, the heating operation of the heating means is stopped.
Such an electric kettle is generally widely sold today, but there are still few published examples of specific application examples, and the prior art cannot be shown in the literature.

ところで、使用者が操作具を移動操作するときに操作具に過度に力が加えられたり、電気ケトルを移動させるときに操作具が他物に当たる等により、操作具に対して加熱停止位置と加熱作動位置との間の正常移動範囲の外部に移動させるように力が印加される場合がある。
そして、このように操作具に対して正常移動範囲の外部に移動させるように力が印加されると、スイッチ手段が故障する虞があるが、従来では対策が講じられておらず、スイッチ手段の寿命を向上するうえで改善の余地があった。 By the way, when the user moves the operating tool, excessive force is applied to the operating tool, or the operating tool hits another object when moving the electric kettle. A force may be applied to move outside the normal movement range between the operating positions.
And when force is applied to the operating tool to move outside the normal movement range in this way, there is a risk that the switch means will break down, but conventionally no countermeasure has been taken and the switch means There was room for improvement in improving the service life.

本発明は、かかる実情に鑑みてなされたものであり、その目的は、スイッチ手段の寿命を向上し得る電気ケトルを提供することにある。 This invention is made | formed in view of this situation, The objective is to provide the electric kettle which can improve the lifetime of a switch means.

本発明の電気ケトルは、貯留している湯水を加熱する加熱手段と、
加熱停止位置と加熱作動位置とに移動操作自在で且つ前記加熱作動位置から前記加熱停止位置に復帰付勢された操作具を備えて、その操作具が前記加熱作動位置に位置する状態で前記加熱手段を加熱作動させ且つ前記操作具が前記加熱停止位置に位置する状態で前記加熱手段の加熱作動を停止させるように構成されたスイッチ手段とが設けられたものであって、
第１特徴構成は、貯留している湯水の加熱が完了する加熱完了条件が満たされない状態において、前記操作具を前記加熱作動位置に保持する保持手段と、
前記加熱完了条件が満たされると、前記操作具が前記保持手段により前記加熱作動位置に保持される状態を解除する解除手段と、
前記操作具が前記加熱停止位置と前記加熱作動位置との間の正常移動範囲の外部に移動されるのを制限するストッパ手段とが設けられている点にある。 The electric kettle of the present invention includes a heating means for heating the stored hot water,
An operating tool that can be moved and operated between a heating stop position and a heating operation position and that is biased back to the heating stop position from the heating operation position is provided, and the heating tool is positioned in the heating operation position. Switch means configured to heat the means and stop the heating operation of the heating means in a state where the operation tool is located at the heating stop position,
The first feature configuration is a holding means for holding the operation tool at the heating operation position in a state where the heating completion condition for completing the heating of the stored hot water is not satisfied,
When the heating completion condition is satisfied, a release unit that releases the state where the operation tool is held at the heating operation position by the holding unit;
Stopper means for restricting movement of the operation tool to the outside of the normal movement range between the heating stop position and the heating operation position is provided.

即ち、操作具を加熱停止位置から加熱作動位置に移動させると、湯水の加熱完了条件が満たされるまで、保持手段によって操作具が加熱作動位置に保持されて加熱手段が加熱作動することになり、貯留している湯水が加熱されることになる。
湯水の加熱が進行して湯水の加熱完了条件が満たされると、操作具が加熱作動位置に保持される状態が解除手段によって解除されるので、加熱手段の加熱作動が自動的に停止されることになる。
そして、操作具を移動操作するときに操作具に過度に力が加えられる等により、以下に説明する例の如く操作具に対して正常移動範囲の外部に移動させるように力が印加されても、ストッパ手段により、操作具が正常移動範囲の外部に移動されるのが制限されることになるので、スイッチ手段の故障を防止することができる。 That is, when the operating tool is moved from the heating stop position to the heating operating position, the operating tool is held at the heating operating position by the holding means until the heating completion condition of the hot water is satisfied, and the heating means is heated. The stored hot water is heated.
When the hot water heating progresses and the hot water heating completion condition is satisfied, the state in which the operation tool is held at the heating operation position is released by the release means, so that the heating operation of the heating means is automatically stopped. become.
Even when a force is applied to the operation tool so that the operation tool is moved outside the normal movement range as in the example described below due to excessive force applied to the operation tool when the operation tool is moved. Since the stopper means restricts the operation tool from being moved outside the normal movement range, it is possible to prevent a failure of the switch means.

操作具に対して正常移動範囲の外部に移動させるように力が印加されるときの例を説明する。ちなみに、操作具を正常移動範囲の外部に移動させるとは、操作具が加熱停止位置に位置する状態のときにその加熱停止位置から加熱作動位置へ向かう方向とは異なる方向に移動させることや、操作具が加熱作動位置に位置する状態のときにその加熱作動位置から加熱停止位置へ向かう方向とは異なる方向に移動させることや、操作具が加熱停止位置と加熱作動位置との間に位置する状態のときに加熱停止位置や加熱作動位置に向かう方向とは異なる方向に移動させることを意味する。
即ち、操作具を加熱停止位置への復帰付勢力に抗して加熱作動位置に移動させると、操作具が保持手段によって加熱作動位置に保持される構造であるので、使用者は、操作具を加熱停止位置から加熱作動位置に移動させるときに過度に力を加え易く、操作具に対して正常移動範囲の外部に移動させるように力が印加され易いものである。
又、操作具が加熱停止位置に位置する状態のときに、操作具に対して加熱停止位置から加熱作動位置に向かう方向とは異なる方向に移動させるように力が加えられる場合があり、このような場合も、操作具に対して正常移動範囲の外部に移動させるように力が印加されることになる。
従って、上記の場合等であっても、加熱完了条件が満たされると加熱手段の加熱作動が自動的に停止される構成として使い勝手を向上させながら、スイッチ手段の寿命を向上し得る電気ケトルを提供することができるようになった。 An example when a force is applied to the operation tool so as to move it outside the normal movement range will be described. By the way, to move the operating tool outside the normal movement range is to move the operating tool in a direction different from the direction from the heating stop position to the heating operation position when the operating tool is in the heating stop position, When the operation tool is in the heating operation position, the operation tool is moved in a direction different from the direction from the heating operation position to the heating stop position, or the operation tool is positioned between the heating stop position and the heating operation position. It means moving in a direction different from the direction toward the heating stop position or the heating operation position in the state.
That is, when the operating tool is moved to the heating operating position against the biasing force to return to the heating stop position, the operating tool is held at the heating operating position by the holding means. When moving from the heating stop position to the heating operation position, an excessive force is easily applied, and the force is easily applied to the operating tool so as to move outside the normal movement range.
In addition, when the operating tool is in the heating stop position, a force may be applied to the operating tool to move in a direction different from the direction from the heating stop position to the heating operation position. Even in such a case, a force is applied to the operation tool so as to move it outside the normal movement range.
Therefore, even in the above case, an electric kettle that can improve the usability and improve the life of the switch means is provided as a configuration in which the heating operation of the heating means is automatically stopped when the heating completion condition is satisfied. I was able to do that.

第２特徴構成は、上記第１特徴構成に加えて、
前記操作具が、前記加熱停止位置及び前記加熱作動位置のうちの一方に対応する上方側の揺動端部位置と他方に対応する下方側の揺動端部位置との間における上下方向での揺動により、前記加熱停止位置と前記加熱作動位置とに移動操作自在に構成され、
前記ストッパ手段が、前記操作具が前記上方側の揺動端部位置から前記外部への移動として、上側、左右側、前後側のいずれかの方向へ移動されるのを制限する第１ストッパ、又は、前記操作具が前記下方側の揺動端部位置から前記外部への移動として、下側、左右側、前後側のいずれかの方向へ移動されるのを制限する第２ストッパの少なくとも１つを備えて構成されている点にある。 In addition to the first feature configuration, the second feature configuration is
The operation tool is vertically movable between an upper swing end position corresponding to one of the heating stop position and the heating operation position and a lower swing end position corresponding to the other. By swinging, it is configured to be movable between the heating stop position and the heating operation position,
A first stopper that restricts movement of the operating tool in any of the upper side, the left and right sides, and the front and rear sides as the movement of the operating tool from the upper swing end position to the outside; Alternatively, at least one of the second stoppers that restricts movement of the operation tool in any of the lower side, the left and right sides, and the front and rear sides as the movement from the position of the lower oscillating end to the outside. It is in the point comprised with one.

即ち、操作具を加熱停止位置及び加熱作動位置のうちの一方に対応する上方側の揺動端部位置と他方に対応する下方側の揺動端部位置との間で揺動させることにより、操作具を加熱停止位置と加熱作動位置とに移動操作する。
そして、ストッパ手段が第１ストッパを備えて構成される場合には、その第１ストッパにより、操作具が上方側の揺動端部位置から上側、左右側、前後側のいずれかの方向へ更に移動されるのを意図的に制限することができるので、スイッチ手段の故障を適切に防止することができる。
又、ストッパ手段が第２ストッパを備えて構成される場合には、その第２ストッパにより、操作具が下方側の揺動端部位置から下側、左右側、前後側のいずれかの方向へ更に移動されるのを意図的に制限することができるので、スイッチ手段の故障を適切に防止することができる。
従って、操作具が上下方向での揺動により加熱停止位置と加熱作動位置とに移動操作される構成において、スイッチ手段の寿命を適切に向上することができるようになった。 That is, by swinging the operating tool between the upper swing end position corresponding to one of the heating stop position and the heating operation position and the lower swing end position corresponding to the other, The operation tool is moved to a heating stop position and a heating operation position.
When the stopper means is configured to include the first stopper, the first stopper further causes the operating tool to move further upward, left and right, and in the front-rear direction from the upper swing end position. Since the movement can be intentionally restricted, the failure of the switch means can be appropriately prevented.
Further, when the stopper means is configured to include the second stopper, the operation tool is moved from the position of the swinging end portion on the lower side to the lower side, the left and right sides, or the front and rear sides by the second stopper. Furthermore, since it can restrict | limit intentionally to move, failure of a switch means can be prevented appropriately.
Therefore, in the configuration in which the operating tool is moved to the heating stop position and the heating operation position by swinging in the vertical direction, the life of the switch means can be appropriately improved.

第３特徴構成は、上記第２特徴構成に加えて、
前記操作具が、少なくとも前後両側が仕切られる形態で上方側に凹入する凹入部を備えるように構成され、
前記第１ストッパ及び第２ストッパが、前記操作具の凹入部内にその下方側から入り込む上向き突起部を備えて、前記操作具の凹入部の内面が前記上向き突起部に当接することにより、少なくとも前記下方側の揺動端部位置から前後側への前記操作具の移動、及び、前記上方側の揺動端部位置から前側への前記操作具の移動を制限するように構成されている点にある。 The third feature configuration is in addition to the second feature configuration,
The operation tool is configured to include a recessed portion that is recessed upward in a form in which at least the front and rear sides are partitioned,
The first stopper and the second stopper each include an upward protruding portion that enters the recessed portion of the operating tool from the lower side thereof, and the inner surface of the recessed portion of the operating tool is in contact with the upward protruding portion, so that at least It is configured to limit movement of the operation tool from the lower swing end position to the front-rear side and movement of the operation tool from the upper swing end position to the front side. It is in.

即ち、操作具に対し下方側の揺動端部位置から前後側へ移動させるように力が印加されても、操作具の凹入部の内面が上向き突起部に当接することにより、下方側の揺動端部位置から前後側への操作具の更なる移動を意図的に制限することができる。
又、操作具に対して上方側の揺動端部位置から前側へ移動させるように力が印加されても、操作具の凹入部の内面が上向き突起部に当接することにより、上方側の揺動端部位置から前側への操作具の更なる移動を意図的に制限することができる。
つまり、上向き突起部を、操作具が正常移動範囲の外部に移動されるのを制限する第１ストッパ及び第２ストッパとして機能させることができるものとなり、ストッパ手段を構成する部材を削減することができる。
従って、ストッパ手段の構成の簡略化により低廉化を図りながら、スイッチ手段の寿命を向上することができるようになった。 In other words, even when a force is applied to the operation tool so as to move from the lower swing end position to the front-rear side, the inner surface of the recessed portion of the operation tool comes into contact with the upward projection, thereby causing the lower swing. Further movement of the operation tool from the moving end position to the front-rear side can be intentionally limited.
Even if a force is applied to the operating tool so that the operating tool is moved from the upper swing end position to the front side, the inner surface of the recessed portion of the operating tool comes into contact with the upward projecting portion, thereby causing the upper swinging motion. Further movement of the operating tool from the moving end position to the front side can be intentionally limited.
That is, the upward protrusion can function as a first stopper and a second stopper that restrict the operation tool from moving outside the normal movement range, and the number of members constituting the stopper means can be reduced. it can.
Therefore, the life of the switch means can be improved while the cost is reduced by simplifying the structure of the stopper means.

第４特徴構成は、上記第１〜第３特徴構成のいずれか１つに加えて、
加熱対象の湯水を貯留する貯留部を内部に備えた本体ボディの側部に、上下方向に延びる状態で棒状のハンドルが設けられ、
前記操作具が、前記ハンドルの下方側である前記本体ボディの側部下方部位に設けられている点にある。 The fourth feature configuration is in addition to any one of the first to third feature configurations,
A bar-like handle is provided in a state extending in the vertical direction on the side portion of the main body provided with a storage portion for storing hot water to be heated.
The operation tool is provided at a lower side portion of the main body, which is a lower side of the handle.

即ち、操作具が、ハンドルの下方側である本体ボディの側部下方部位に設けられているので、使用者がハンドルを握ったり離したりするときに、誤って操作具を移動操作するのを防止することができ、しかも、ハンドルを手前側に向けた姿勢で本体ボディをテーブル等に置くと、その本体ボディの姿勢を変えることなく、ハンドルの持ち離しと操作具の操作を行うことができる。
従って、ハンドルの持ち離し及び操作具の操作における操作性を低下させることなく、操作具の誤操作を防止することができるようになった。 In other words, since the operating tool is provided in the lower part of the side of the main body, which is the lower side of the handle, it is possible to prevent the user from moving the operating tool by mistake when holding or releasing the handle. In addition, when the main body is placed on a table or the like with the handle directed toward the front, the handle can be released and the operation tool can be operated without changing the posture of the main body.
Accordingly, it is possible to prevent erroneous operation of the operation tool without deteriorating the handleability of the handle and the operation of the operation tool.

図６及び図７に示すように、前記受電機構１７、前記スイッチ手段Ｓ、前記保持手段Ｋ及び前記解除手段Ｒは、連動ユニット１８として一体的に構成されている。
この連動ユニット１８は、電気ケトル１において広く使用されているものであり、詳細な説明を省略して簡単に説明すると、底部側に前記給電機構嵌め込み用凹部１８ｄが形成されたユニット本体１８ａと、そのユニット本体１８ａから横方向に延びる固定腕部１８ｂと、その固定腕部１８ｂの上方にその固定腕部１８ｂに対向する状態で上下方向に揺動自在に設けられた揺動腕部１８ｃとを備えて構成され、その揺動腕部１８ｃの遊端に、その揺動腕部１８ｃと一体的に揺動操作自在なように前記操作具１５が連結されている。 As shown in FIGS. 6 and 7, the power receiving mechanism 17, the switch means S, the holding means K, and the release means R are integrally configured as an interlocking unit 18.
This interlocking unit 18 is widely used in the electric kettle 1, and will be described briefly without detailed description. A unit main body 18a in which the power supply mechanism fitting recess 18d is formed on the bottom side; A fixed arm portion 18b extending laterally from the unit main body 18a, and a swing arm portion 18c provided above the fixed arm portion 18b and swingable in the vertical direction in a state of facing the fixed arm portion 18b. The operating tool 15 is connected to the free end of the swing arm portion 18c so as to be swingable integrally with the swing arm portion 18c.

揺動腕部１８ｃは、上方に復帰付勢された状態で上下方向に揺動自在に設けられており、その揺動腕部１８ｃに連結された前記操作具１５は、加熱停止位置に対応する上方側の揺動端部位置と加熱作動位置に対応する下方側の揺動端部位置との間における上下方向での揺動により、加熱停止位置と加熱作動位置とに移動操作自在に構成されていることになる。 The swing arm portion 18c is provided so as to be swingable in the vertical direction in a state where the swing arm portion 18c is returned upwardly biased, and the operation tool 15 connected to the swing arm portion 18c corresponds to the heating stop position. It is configured to be movable between the heating stop position and the heating operation position by swinging in the vertical direction between the upper swing end position and the lower swing end position corresponding to the heating operation position. Will be.

そして、操作具１５が復帰付勢力により上方側の揺動端部の加熱停止位置に位置する状態では、スイッチ手段Ｓがオフ状態であって電気ヒータ１６の加熱作動を停止させる状態であり、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にて、操作具１５を下方側に移動させて下方側の揺動端部の加熱作動位置に位置させると、スイッチ手段Ｓがオン状態に切り換えられて電気ヒータ１６を加熱作動させる状態となる。 When the operating tool 15 is positioned at the heating stop position of the upper swing end by the return biasing force, the switch means S is in the off state and the heating operation of the electric heater 16 is stopped. When the operation tool 15 is moved downward in the power supply state in which the kettle body 3 is placed on the plate 2 and is positioned at the heating operation position of the swinging end portion on the lower side, the switch means S is turned on. The electric heater 16 is heated and activated.

前記保持手段Ｋは、図示を省略するが、操作具１５の加熱作動位置への移動によりスイッチ手段Ｓがオン状態に切り換えられて電流が流れることにより発生する磁気力により、加熱停止位置への復帰付勢力に抗して、操作具１５を加熱作動位置に、即ち、スイッチ手段Ｓをオン状態に保持するように構成されている。 Although not shown, the holding means K is returned to the heating stop position by the magnetic force generated when the switch means S is turned on by the movement of the operation tool 15 to the heating operation position and current flows. The operating tool 15 is held at the heating operation position, that is, the switch means S is kept in an on state against the urging force.

この実施形態では、前記加熱完了条件は、貯留部６に貯留している湯水が沸騰する条件に設定され、解除手段Ｒは、湯水が沸騰することにより発生する蒸気に感応して変形する蒸気感応板１９にて構成されている。
そして、蒸気感応板１９は、蒸気に感応して変形すると、加熱作動位置に位置している揺動腕部１８ｃの底面に当接してその揺動腕部１８ｃを押し上げるように、連動ユニット１８に設けられている。 In this embodiment, the heating completion condition is set to a condition in which the hot water stored in the storage unit 6 is boiled, and the release means R is a steam sensitive that deforms in response to the steam generated by boiling the hot water. It consists of a plate 19.
When the steam sensitive plate 19 is deformed in response to steam, the steam sensitive plate 19 contacts the bottom surface of the swing arm portion 18c positioned at the heating operation position and pushes up the swing arm portion 18c. Is provided.

そして、貯留部６内の湯水が沸騰すると、その湯から発生する蒸気が蒸気路２０を通して蒸気感応板１９に導かれることになって、その蒸気感応板１９が変形して揺動腕部１８ｃが上方に押し上げられて、操作具１５が加熱作動位置に保持されている状態が解除されて加熱停止位置に復帰するので、スイッチ手段Ｓがオフ状態に切り換えられて電気ヒータ１６の加熱作動が停止することになる。 That is, when the operating tool 15 is pushed down to the heating operation position as shown by a one-dot chain line in FIG. 7 with the kettle body 3 placed on the power supply plate 2, the hot water in the storage unit 6 is not boiling. Then, since the steam is not guided to the steam sensitive plate 19 and the steam sensitive plate 19 is not deformed, the operation tool 15 is held in the heating operation position and the switch means S is held in the ON state. The electric heater 16 is heated and the hot water in the reservoir 6 is heated.
And when the hot water in the storage part 6 boils, the vapor | steam which generate | occur | produces from the hot water will be guide | induced to the vapor | steam sensitive plate 19 through the vapor | steam path 20, and the vapor | steam sensitive plate 19 will deform | transform and the rocking | fluctuation arm part 18c will become. The state in which the operation tool 15 is held at the heating operation position is released by being pushed upward, and returns to the heating stop position, so that the switch means S is switched off and the heating operation of the electric heater 16 is stopped. It will be.

Even if a force is applied to the operation tool 15 in a state of moving between the stop position and the heating operation position of the lower oscillating end portion so as to move it to the left side or the right side, Further movement to the left side or the right side is restricted by the right movement restriction columnar portion 36.

〔別実施形態〕
次に別実施形態を説明する。
（１）操作具１５が加熱停止位置と加熱作動位置との間の正常移動範囲の外部に移動されるのを制限するための操作具１５及びストッパ手段Ｇの具体構成は、上記の実施形態において例示した構成に限定されるものではない。
例えば、操作具１５に備える凹入部１５ｅを、前後左右の四方が仕切られた穴状に形成し、上向き突起部３１を、操作具１５が上方側の揺動端部の加熱停止位置、下方側の揺動端部の加熱作動位置及びそれらの間のいずれに位置する状態においても、操作具１５の凹入部１５ｅ内に入り込むように構成する。
そして、操作具１５が上方側の揺動端部の加熱停止位置、下方側の揺動端部の加熱作動位置及びそれらの間のいずれに位置する状態においても、前後、左右方向に力が印加された場合に、操作具１５の凹入部１５ｅの内面が上向き突起部３１のいずれかの部分に当接するように構成して、操作具１５が前後左右に移動するのを制限することもできる。この場合、上記の実施形態において設けた後側移動制限用柱状部３３、左側移動制限用柱状部３５及び右側移動制限用柱状部３６を省略することができる。 [Another embodiment]
Next, another embodiment will be described.
(1) The specific configurations of the operation tool 15 and the stopper means G for restricting the operation tool 15 from being moved outside the normal movement range between the heating stop position and the heating operation position are as described in the above embodiment. The configuration is not limited to the exemplified configuration.
For example, the recessed portion 15e provided in the operation tool 15 is formed in a hole shape in which the front, rear, left and right sides are partitioned, and the upward projection 31 is formed at the heating stop position of the swinging end on the upper side, the lower side. The oscillating end portion of the operating tool 15 is configured to enter the recessed portion 15e of the operating tool 15 in any of the heating operation positions and the state between them.
A force is applied in the front-rear and left-right directions regardless of whether the operation tool 15 is positioned at the heating stop position of the upper swing end, the heating operation position of the lower swing end, or any position therebetween. In this case, the inner surface of the recessed portion 15e of the operation tool 15 can be configured to abut against any portion of the upward projection 31 to restrict the operation tool 15 from moving back and forth and from side to side. In this case, the rear side movement limiting columnar part 33, the left side movement limiting columnar part 35, and the right side movement limiting columnar part 36 provided in the above embodiment can be omitted.

又、上記の実施形態においては、ストッパ手段Ｇを第１ストッパＧ１及び第２ストッパＧ２の両方を備えて構成したが、いずれか一方を備えて構成しても良い。 In the above embodiment, the stopper means G is configured to include both the first stopper G1 and the second stopper G2, but may be configured to include either one.

（２）操作具１５における加熱停止位置と加熱作動位置との間の移動形態は、上記の実施形態において例示した上下方向での揺動による移動形態に限定されるものではない。
例えば、横方向での揺動による移動形態や、横方向の軸心周りでの揺動による移動形態でも良い。 (2) The movement mode between the heating stop position and the heating operation position in the operation tool 15 is not limited to the movement mode by swinging in the vertical direction exemplified in the above embodiment.
For example, a moving form by swinging in the lateral direction or a moving form by swinging around the axis in the lateral direction may be used.

（３）加熱完了条件が満たされたか否かの検出は、湯水の沸騰による蒸気を検知する構成に限らず、湯水の温度を直に検知したり、予測検知することで検出する構成とすることもできる。この場合は、例えば、貯留部６内の湯水の温度を検出する温度センサを設け、解除手段Ｒを、操作具１５が保持手段Ｋにより加熱作動位置に保持される状態を解除するように作動するアクチュエータを備えて構成して、前記温度センサの検出温度が加熱目標温度に達すると前記アクチュエータを作動させる制御手段を設けることもできる。
ちなみに、前記加熱目標温度は、１００℃に限らず、１００℃より低い温度でも良い。 (3) The detection of whether or not the heating completion condition is satisfied is not limited to the configuration for detecting steam due to boiling of hot and cold water, but is configured to detect by detecting the temperature of hot water directly or by predicting it. You can also. In this case, for example, a temperature sensor that detects the temperature of the hot water in the storage unit 6 is provided, and the release unit R operates to release the state in which the operation tool 15 is held at the heating operation position by the holding unit K. An actuator may be provided to provide a control means for operating the actuator when the temperature detected by the temperature sensor reaches the heating target temperature.
Incidentally, the heating target temperature is not limited to 100 ° C., and may be a temperature lower than 100 ° C.
