Description

本発明は、上方側が開口し、内部に貯留部を有する容器本体と、貯留部内の液体を加熱する加熱機構と、容器本体の上方開口部を開閉自在な蓋体とを備えた湯沸し器に関する。   The present invention relates to a water heater provided with a container body having an opening on the upper side and having a storage part therein, a heating mechanism for heating a liquid in the storage part, and a lid that can open and close the upper opening part of the container body.

この種の湯沸し器としては、電気ケトルや電気ポット等が例示できるが、特許文献１に開示された電気ケトルでは、上面視における電気ケトルの前後方向において、前方側に注ぎ口、後方側に把手、注ぎ口と把手との間に蒸気口を設けた構成が開示されている。
この電気ケトルでは、蓋体の内部に、貯留部と外部とを連通し、貯留部内の液体を注ぎ口を介して外部に通流させる注出流路と、貯留部と外部とを連通し、貯留部内の蒸気を蒸気口を介して外部に通流させる蒸気流路とを備えており、貯留部内で発生した蒸気が、蒸気流路を通流して、貯留部の上方に位置する蓋体の上面に開口形成された蒸気口から外部に排出されるように構成されている。 Examples of this type of water heater include an electric kettle and an electric kettle. However, in the electric kettle disclosed in Patent Document 1, a spout is provided on the front side and a handle on the rear side in the front-rear direction of the electric kettle in a top view. A configuration in which a steam port is provided between the spout and the handle is disclosed.
In this electric kettle, the storage portion and the outside are communicated with the inside of the lid, the discharge channel for allowing the liquid in the storage portion to flow to the outside through the spout, and the storage portion and the outside are communicated. A steam flow path for allowing the steam in the storage section to flow to the outside through the steam port, and the steam generated in the storage section flows through the steam flow path and is positioned above the storage section. It is configured to be discharged to the outside through a steam port formed in the upper surface.

しかしながら、蓋体の上面に蒸気口が開口形成されていると、子供等が蒸気口から排出された蒸気に触れてしまう可能性があり、好ましい構成とは言えない。
また、貯留部で発生した蒸気が、貯留部内から上昇する際の流速を維持したまま、比較的短く形成された蒸気流路を通流して蒸気口から外部に排出されるため、蒸気量が比較的多くなる傾向があり、外部（室内等）の湿度が上昇し、結露やカビ等の発生も懸念される。 However, if a steam port is formed in the upper surface of the lid, a child or the like may touch the steam discharged from the steam port, which is not a preferable configuration.
In addition, the steam generated in the reservoir is discharged to the outside through the steam channel formed through a relatively short steam channel while maintaining the flow rate when rising from the inside of the reservoir. There is a concern that the humidity of the outside (indoors, etc.) will rise, and that condensation and mold will occur.

そこで、特許文献２及び３では、蒸気流路を、貯留部と外部とを連通するのではなく、貯留部と注出流路とを連通することにより、貯留部内で発生した蒸気を、蒸気流路及び注出流路に通流させて、注ぎ口を介して外部に排出させる電気ケトルが開示されている。
これにより、蒸気が、比較的長く形成された蒸気流路及び注出流路を通流する際に結露して、注ぎ口から排出される蒸気量を低減することができ、子供等が注ぎ口から排出される蒸気に触れる可能性が低下するとともに、外部（室内等）の湿度の上昇を低減することができる。 Therefore, in Patent Documents 2 and 3, the steam flow path is not connected between the storage section and the outside, but the steam generated in the storage section is generated by connecting the storage section and the extraction flow path. There is disclosed an electric kettle that is caused to flow through a channel and a pouring channel and is discharged to the outside through a spout.
As a result, when the steam flows through the steam flow path and the discharge flow path formed relatively long, the amount of steam discharged from the spout can be reduced. The possibility of touching the steam discharged from the air is reduced, and an increase in humidity outside the room (such as indoors) can be reduced.

特開２００９−１７２１７２号公報JP 2009-172172 A 特開２００８−２１２３１５号公報JP 2008-212315 A 特開２０１２−１７０７０６号公報JP 2012-170706 A

ここで、特許文献２及び３に記載の電気ケトルでは、蒸気流路及び注出流路が蓋体の内部において、略水平方向に延出（具体的には、上面視における電気ケトルの前後方向において、後方側の把手側から前方側の注ぎ口側に向けて延出）するように設けられている。
このような場合、貯留部内から発生した蒸気は、水平方向に延出する蒸気流路及び注出流路内を通流し、注ぎ口を介して外部に排出されるが、貯留部内から上昇する際の流速を比較的維持したまま蒸気流路及び注出流路を水平方向に沿って順次通流し、その後、注ぎ口から排出されることとなる。このため、蒸気が比較的長く形成された蒸気流路及び注出流路を通流する場合であっても、当該蒸気の大部分が注ぎ口から排出されることとなる。従って、子供等が注ぎ口から排出される蒸気に触れてしまう可能性が残るとともに、外部（室内）の湿度も上昇する。
よって、注ぎ口から排出される蒸気の量を、より低減することが望まれる。 Here, in the electric kettles described in Patent Documents 2 and 3, the steam flow channel and the extraction flow channel extend in a substantially horizontal direction inside the lid (specifically, the front and rear direction of the electric kettle in a top view). In FIG. 2, the projection extends from the rear handle side toward the front spout side.
In such a case, the steam generated from the inside of the storage part flows through the steam channel and the extraction channel extending in the horizontal direction, and is discharged to the outside through the spout. The steam flow channel and the discharge flow channel are sequentially passed along the horizontal direction while maintaining a relatively high flow rate, and then discharged from the spout. For this reason, even when the steam flows through the steam channel and the extraction channel formed relatively long, most of the steam is discharged from the spout. Therefore, there is a possibility that a child or the like may come into contact with the steam discharged from the spout, and the external (indoor) humidity also increases.
Therefore, it is desired to further reduce the amount of steam discharged from the spout.

また、電気ケトルにおいて、注ぎ口から排出される蒸気の量を低減させるための構成を採用する際、蓋体の構成の複雑化を防止する観点から、簡便でコンパクトな構成を採用することが望まれる。   Further, in the electric kettle, when adopting a configuration for reducing the amount of steam discharged from the spout, it is desirable to adopt a simple and compact configuration from the viewpoint of preventing the configuration of the lid from becoming complicated. It is.

本発明は、上述の実情に鑑みて為されたものであり、その主たる課題は、できるだけ簡便且つコンパクトな構成で、注ぎ口から排出される蒸気の量を確実に低減することができる湯沸し器を提供する点にある。   The present invention has been made in view of the above circumstances, and a main problem thereof is a water heater that can reliably reduce the amount of steam discharged from the spout with a simple and compact configuration as much as possible. The point is to provide.

上記目的を達成するための本発明に係る湯沸し器は、上方側が開口し、内部に貯留部を有する容器本体と、前記貯留部内の液体を加熱する加熱機構と、前記容器本体の上方開口部を開閉自在な蓋体とを備えた湯沸し器であって、その特徴構成は、
前記蓋体の内部に、前記貯留部と外部とを連通し、前記貯留部内の液体を注ぎ口を介して外部に通流させる注出流路と、前記注出流路に設けられ、前記注出流路を開閉自在な弁機構と、前記貯留部と前記注出流路における前記弁機構の下流側とを連通し、前記貯留部内の液体から発生する蒸気を前記注出流路における前記弁機構の下流側に通流させる蒸気流路とを備え、
前記蒸気流路が、水平方向に延出し、蒸気導入口を介して前記貯留部に連通する水平向き流路と、当該水平向き流路から下方側に延出し、下流側端部に形成された蒸気導出口を介して前記注出流路における弁機構の下流側に連通する下方向き流路とを備えた点にある。 In order to achieve the above object, a water heater according to the present invention comprises: a container body having an opening on the upper side and having a storage part therein; a heating mechanism for heating the liquid in the storage part; and an upper opening part of the container body. A water heater provided with a lid that can be freely opened and closed.
An inside of the lid is provided in the pouring channel, the pouring channel for communicating the reservoir and the outside, and allowing the liquid in the reservoir to flow to the outside through a spout. A valve mechanism that can open and close the outlet channel, and the reservoir and the downstream side of the valve mechanism in the outlet channel, communicate the vapor generated from the liquid in the reservoir with the valve in the outlet channel. A steam flow path that allows the downstream of the mechanism to flow,
The steam channel extends in a horizontal direction and communicates with the storage unit via a steam inlet, and extends downward from the horizontal channel and is formed at a downstream end. There is a downward flow path that communicates with the downstream side of the valve mechanism in the extraction flow path via a steam outlet.

上記特徴構成によれば、基本的に、蓋体の内部に、貯留部と外部とを連通し、貯留部内の液体を注ぎ口を介して外部に通流させる注出流路と、注出流路に設けられ、注出流路を開閉自在な弁機構と、貯留部と注出流路における弁機構の下流側とを連通し、貯留部内の液体から発生する蒸気を注出流路における弁機構の下流側に通流させる蒸気流路とを備えているので、加熱機構による貯留部内の液体の加熱により貯留部内にて発生した蒸気を、比較的長い流路となる貯留部、蒸気流路、注出流路、注ぎ口の順に通流させ順次温度を低下させて、蒸気流路及び注出流路内で結露させることができ、注ぎ口から排出される蒸気の量をある程度低減することができる。この際、蓋体の上面に蒸気口を開口形成する必要がないので、蓋体の上面から蒸気が排出されることが無く、子供等が蒸気に触れる可能性を低減することができる。   According to the above characteristic configuration, basically, the inside of the lid body is connected to the storage portion and the outside, and the liquid in the storage portion is allowed to flow to the outside through the spout. A valve mechanism that is provided in the channel and that can freely open and close the extraction flow path, and a reservoir that communicates with the downstream side of the valve mechanism in the extraction flow path, and that generates steam generated from the liquid in the storage section. A steam flow path that allows the downstream of the mechanism to flow, so that the steam generated in the storage section due to the heating of the liquid in the storage section by the heating mechanism is a relatively long flow path. It is possible to allow the condensation to flow in the steam flow path and the discharge flow path by reducing the temperature by passing through the discharge flow path and the spout in order, and to reduce the amount of steam discharged from the spout to some extent. Can do. At this time, since it is not necessary to form a steam port on the upper surface of the lid, the steam is not discharged from the upper surface of the lid, and the possibility that a child or the like touches the steam can be reduced.

特に、蒸気流路が、水平方向に延出し、蒸気導入口を介して貯留部に連通する水平向き流路と、当該水平向き流路から下方側に延出し、下流側端部に形成された蒸気導出口を介して注出流路における弁機構の下流側に連通する下方向き流路とを備えているので、貯留部内で発生した蒸気は上昇して、まず、蒸気導入口を介して水平向き流路内を通流し、その後、水平向き流路から下方側に延出し且つ当該水平向き流路の下流側に位置する下方向き流路内を通流して、下方向き流路の下流側端部に形成された蒸気導出口を介して注出流路内を通流し、注ぎ口に到達することとなる。
従って、蒸気導入口から導入され水平向き流路内を水平方向に沿って通流する蒸気は、下方向き流路に導入される際に当該下方向き流路内を下方向に沿って通流するように強制的に方向変換させられるため、下方向き流路の入り口付近である程度の蒸気の滞留が発生する。即ち、蒸気が下方向き流路に導入される際には、比較的高温の蒸気が上昇しようとする方向（上方向）とは反対側の下方向に強制的に方向変換させられるので、当該蒸気の流速を良好に弱めることができるのである。
これにより、下方向き流路内を通流する蒸気の流速は比較的低下した状態となり、蒸気が水平向き流路及び下方向き流路内を通流する流速を低下させることができ、当該蒸気の温度低下を促進し結露を促進させることができる。更に、当該蒸気を、下方向き流路の下流側端部に形成された蒸気導出口を介して注出流路内に導出し、注ぎ口を介して外部に排出するので、注ぎ口から排出される蒸気を低減することができる。
従って、子供等が蒸気に触れる可能性を低減することができ、また、外部（室内）の湿度の上昇も低減することができる。 In particular, the steam channel extends in the horizontal direction and communicates with the storage part via the steam inlet, and extends downward from the horizontal channel and is formed at the downstream end. Since the downward flow path that communicates with the downstream side of the valve mechanism in the discharge flow path is provided via the steam outlet, the steam generated in the reservoir rises and is first leveled via the steam inlet. Flow in the downward flow path, and then extend downward from the horizontal flow path and flow in the downward flow path located on the downstream side of the horizontal flow path. It will flow through the inside of the extraction flow path through the vapor outlet formed in the part, and will reach the spout.
Therefore, the steam introduced from the steam inlet and flowing in the horizontal flow path along the horizontal direction flows in the downward flow path along the downward direction when introduced into the downward flow path. As a result, the steam is forcibly changed in the vicinity of the entrance of the downward flow path. That is, when steam is introduced into the downward flow path, the steam is forced to change in the downward direction opposite to the direction in which the relatively high-temperature steam is going to rise (upward). It is possible to satisfactorily weaken the flow rate.
As a result, the flow velocity of the steam flowing through the downward flow path becomes relatively low, and the flow velocity of the vapor flowing through the horizontal flow path and the downward flow path can be reduced. It is possible to promote a decrease in temperature and condensation. Further, since the steam is led out into the pouring channel through the steam outlet formed in the downstream end of the downward channel and is discharged to the outside through the pouring port, the steam is discharged from the pouring port. Steam can be reduced.
Therefore, it is possible to reduce the possibility that children and the like will come into contact with steam, and to reduce the increase in humidity outside the room (indoors).

また、蓋体の上下方向の厚みを利用して下方向き流路を形成することで、蓋体内における省スペース化及びコンパクト化を図ることができる。   Further, by forming the downward flow path by using the thickness in the vertical direction of the lid, it is possible to achieve space saving and compactness in the lid.

さらに、蒸気流路における水平向き流路及び下方向き流路内で結露した結露水は、蒸気導出口を介して注出流路に戻すことができるので、蒸気流路内に結露水が滞留することは良好に防止されている。   Further, the condensed water condensed in the horizontal flow path and the downward flow path in the steam flow path can be returned to the extraction flow path through the steam outlet, so that the condensed water stays in the steam flow path. That is well prevented.

よって、上述の下方向き流路を設けるという非常に簡便且つコンパクトな構成で、注ぎ口から排出される蒸気の量を確実に低減することができる湯沸し器を得ることができた。   Therefore, the water heater which can reduce reliably the quantity of the vapor | steam discharged | emitted from a spout with the very simple and compact structure of providing the above-mentioned downward flow path was able to be obtained.

本発明に係る湯沸し器の更なる特徴構成は、前記注出流路と上下方向で重なる位置に、前記水平向き流路及び前記下方向き流路の少なくとも一部を設けた点にある。   A further characteristic configuration of the water heater according to the present invention is that at least a part of the horizontal flow path and the downward flow path is provided at a position overlapping the pouring flow path in the vertical direction.

上記特徴構成によれば、水平向き流路及び下方向き流路の少なくとも一部が、注出流路と上下方向で重なる位置に設けられているので、蓋体内における上下方向及び水平方向のコンパクト性を確保した上で、水平向き流路及び下方向き流路の流路長を長くすることができる。   According to the above characteristic configuration, since at least a part of the horizontal flow path and the downward flow path is provided at a position overlapping the extraction flow path in the vertical direction, the vertical and horizontal compactness in the lid body. In addition, it is possible to increase the channel lengths of the horizontal channel and the downward channel.

本発明に係る湯沸し器の更なる特徴構成は、上面視における前記湯沸し器の前後方向において、前方側に前記注ぎ口を設け、後方側に把手を設け、
前記水平向き流路が、前記前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路を備え、
前記下方向き流路が、前記水平向き分岐流路のそれぞれから延出形成される点にある。 A further characteristic configuration of the water heater according to the present invention is that, in the front-rear direction of the water heater in a top view, the spout is provided on the front side, and a handle is provided on the rear side.
The horizontal flow path is disposed along the front-rear direction, and includes a horizontal branch flow path that branches at least in the left-right direction with respect to the front-rear direction,
The downward-facing flow path is formed by extending from each of the horizontal branch flow paths.

上記特徴構成によれば、上面視における湯沸し器の前後方向において、前方側に注ぎ口、後方側に把手を設けているので、ユーザは把手を把持して、把手に対して反対側に設けられた注ぎ口側が下方となるように傾けることにより、貯留部内の液体を注ぎ口から外部に通流させることができる。
この際、注ぎ口から通流する液体と入れ換わるように、注ぎ口を介して外部から注出流路内に空気が流入し、注ぎ口から外部に通流する液体の脈動（いわゆる息継ぎ）が発生する場合がある。
しかしながら、水平向き流路が前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路を備え、下方向き流路が水平向き分岐流路のそれぞれから延出形成されるので、下方向き流路の下流側端部に複数の蒸気導出口を配置することができ、上述のように、注ぎ口から外部に液体を通流させる場合でも、蓋体内の空気を複数の蒸気導出口の少なくとも一つから導入して、当該蒸気導出口、蒸気流路の下方向き流路及び水平向き流路、更には蒸気導入口を介して貯留部内に供給し、注ぎ口から外部に通流する液体の脈動（いわゆる息継ぎ）を良好に防止することができる。 According to the above characteristic configuration, in the front-rear direction of the water heater in a top view, the spout is provided on the front side and the handle is provided on the rear side, so that the user holds the handle and is provided on the opposite side of the handle. By tilting so that the pouring side is downward, the liquid in the reservoir can be allowed to flow from the pouring port to the outside.
At this time, air flows from the outside into the extraction flow path through the pouring spout so that the liquid flowing from the pouring spout is replaced, and pulsation (so-called breathing) of the liquid flowing from the pouring spout to the outside occurs. May occur.
However, the horizontal flow path is disposed along the front-rear direction, and includes a horizontal branch flow path that branches at least in the left-right direction with respect to the front-rear direction. As described above, a plurality of vapor outlets can be arranged at the downstream end of the downward flow path, and as described above, even when liquid is allowed to flow from the spout to the outside, Air is introduced from at least one of the plurality of steam outlets, and the steam outlet, the downward channel and the horizontal channel of the steam channel, and further supplied into the reservoir through the steam inlet, The pulsation (so-called breathing) of the liquid flowing from the spout to the outside can be satisfactorily prevented.

本発明に係る湯沸し器の更なる特徴構成は、前記下方向き流路が、前記水平向き流路の下流側端部から延出形成される点にある。   A further characteristic configuration of the water heater according to the present invention is that the downward flow path is formed to extend from the downstream end of the horizontal flow path.

上記特徴構成によれば、下方向き流路が水平向き流路の下流側端部から延出形成されるので、水平向き流路内から下方向き流路内へ通流する蒸気は、水平向き流路の下流側端部の壁面に衝突して水平方向から下方向に強制的に方向変換することとなり、当該蒸気の流速が確実に弱められた状態で、下方向き流路内を通流することとなる。
これにより、蒸気が水平向き流路及び下方向き流路内を通流する流速を一層低下させることができ、当該蒸気の温度低下を一層促進し結露を促進して、蒸気の量をより一層低減することができる。
また、蒸気流路における水平向き流路及び下方向き流路内で結露した結露水は、水平向き流路の下流側端部に残留することなく、蒸気導出口を介して注出流路に戻すことができる。 According to the above characteristic configuration, the downward flow path is formed to extend from the downstream end of the horizontal flow path, so that the steam flowing from the horizontal flow path into the downward flow path flows horizontally. It collides with the wall surface at the downstream end of the passage and forcibly changes its direction from the horizontal direction to the downward direction, and flows in the downward flow path in a state where the flow velocity of the steam is surely weakened. It becomes.
As a result, the flow rate of the steam flowing in the horizontal flow path and the downward flow path can be further reduced, further reducing the temperature of the steam and promoting condensation, further reducing the amount of steam. can do.
Further, the condensed water condensed in the horizontal channel and the downward channel in the steam channel returns to the extraction channel via the steam outlet without remaining at the downstream end of the horizontal channel. be able to.

本発明に係る湯沸し器の更なる特徴構成は、上面視における前記湯沸し器の前後方向において、前方側に前記注ぎ口を設け、後方側に把手を設け、
前記水平向き流路が、前記前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路を備え、
前記下方向き流路が、前記水平向き分岐流路において、前記前後方向に対して前記左右方向で最も離間する端部位置のそれぞれから延出形成される点にある。 A further characteristic configuration of the water heater according to the present invention is that, in the front-rear direction of the water heater in a top view, the spout is provided on the front side, and a handle is provided on the rear side.
The horizontal flow path is disposed along the front-rear direction, and includes a horizontal branch flow path that branches at least in the left-right direction with respect to the front-rear direction,
The downward flow path is formed in the horizontal branch flow path so as to extend from each of the end positions farthest in the left-right direction with respect to the front-rear direction.

上記特徴構成によれば、上面視における湯沸し器の前後方向において、前方側に注ぎ口、後方側に把手を設けているので、ユーザは把手を把持して、把手に対して反対側に設けられた注ぎ口側が下方となるように傾けることにより、貯留部内の液体を注ぎ口から外部に通流させることができる。
この際、注ぎ口から通流する液体と入れ換わるように、注ぎ口を介して外部から注出流路内に空気が流入し、注ぎ口から外部に通流する液体の脈動（いわゆる息継ぎ）が発生する場合がある。
しかしながら、水平向き流路が前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路を備え、下方向き流路が、水平向き分岐流路において、前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成されるので、下方向き流路の下流側端部に複数の蒸気導出口を配置することができ、上述のように、注ぎ口から外部に液体を通流させる場合でも、蓋体内の空気を複数の蒸気導入口の少なくとも一つから導入して、当該蒸気導入口、蒸気流路の下方向き流路及び水平向き流路、更には蒸気導入口を介して貯留部内に供給し、注ぎ口から外部に通流する液体の脈動（いわゆる息継ぎ）を良好に防止することができる。 According to the above characteristic configuration, in the front-rear direction of the water heater in a top view, the spout is provided on the front side and the handle is provided on the rear side, so that the user holds the handle and is provided on the opposite side of the handle. By tilting so that the pouring side is downward, the liquid in the reservoir can be allowed to flow from the pouring port to the outside.
At this time, air flows from the outside into the extraction flow path through the pouring spout so that the liquid flowing from the pouring spout is replaced, and pulsation (so-called breathing) of the liquid flowing from the pouring spout to the outside occurs. May occur.
However, the horizontal flow path is disposed along the front-rear direction, and includes a horizontal branch flow path that branches at least in the left-right direction with respect to the front-rear direction. Since it is formed to extend from each of the end positions that are farthest apart in the left-right direction with respect to the front-rear direction, a plurality of steam outlets can be arranged at the downstream end of the downward-facing channel, as described above In addition, even when liquid is allowed to flow from the spout to the outside, the air in the lid body is introduced from at least one of the plurality of steam inlets, and the steam inlet, the downward channel of the steam channel, and the horizontal direction It is possible to satisfactorily prevent the pulsation (so-called breathing) of the liquid that is supplied into the reservoir through the flow path and further through the steam inlet and flows from the spout to the outside.

また、上面視における湯沸し器の前後方向において、前方側に注ぎ口、後方側に把手を設けているので、湯沸し器がテーブル等の上面で転倒した際には、湯沸し器の前後方向がテーブルの上面と略平行で、湯沸し器の左右方向がテーブルの上面に対して略垂直な状態となる。
この際、蒸気流路の水平向き流路内に結露水が滞留していると、当該結露水は、自重により、水平向き流路内においてテーブルの上面に対して垂直方向で最も近接する位置（下方側）に存在することとなる。即ち、当該結露水は、水平向き流路内において湯沸し器の前後方向に対して左右方向で最も離間した端部位置に存在することとなる。
そして、下方向き流路が、水平向き分岐流路において、前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成されるので、湯沸し器が転倒した際に水平向き流路内に滞留する結露水を確実に下方向き流路を介して注出流路に通流させることができ水平向き流路内に結露水が滞留することは良好に防止されている。 In addition, since the spout is provided on the front side and the handle is provided on the rear side in the front-rear direction of the water heater in a top view, when the water heater falls on the upper surface of a table or the like, the front-rear direction of the water heater is The horizontal direction of the water heater is substantially perpendicular to the upper surface of the table, being substantially parallel to the upper surface.
At this time, if the condensed water stays in the horizontal flow path of the steam flow path, the condensed water is positioned closest to the upper surface of the table in the vertical direction in the horizontal flow path due to its own weight ( Will be present on the lower side). That is, the dew condensation water is present at the end position farthest in the left-right direction with respect to the front-rear direction of the water heater in the horizontal flow path.
And since the downward flow path is formed to extend from each of the end positions farthest in the left-right direction with respect to the front-rear direction in the horizontal branch flow path, the horizontal flow path when the water heater falls Condensed water staying inside can be surely passed through the outlet flow path through the downward flow path, and it is well prevented that the dew condensation water stays in the horizontal flow path.

本発明に係る湯沸し器の更なる特徴構成は、前記下方向き流路の少なくとも一部が、前記水平向き流路の流路断面積よりも小さな流路断面積の絞り部として形成されている点にある。   A further characteristic configuration of the water heater according to the present invention is that at least a part of the downward channel is formed as a throttle portion having a channel cross-sectional area smaller than the channel cross-sectional area of the horizontal channel. It is in.

上記特徴構成によれば、下方向き流路の少なくとも一部が、水平向き流路の流路断面積よりも小さな流路断面積の絞り部とされているので、当該絞り部を通流する蒸気の通流を阻害して、当該蒸気が通流する流速を低減することができ、当該絞り部よりも上流側の箇所（絞り部よりも上流側の下方向き流路及び水平向き流路）に蒸気をある程度滞留させることができる。
これにより、絞り部の上流側の箇所での蒸気の結露を促進し、注出流路に導出される蒸気の量をより一層低減することができる。 According to the above characteristic configuration, since at least a part of the downward-facing flow path is a throttle portion having a smaller channel cross-sectional area than the horizontal-direction flow passage, the steam flowing through the throttle portion The flow velocity of the steam can be reduced, and the upstream side of the throttle part (downward and horizontal channels upstream of the throttle part) can be reduced. Steam can be retained to some extent.
Thereby, the dew condensation of the vapor | steam in the location of the upstream of a throttle part can be accelerated | stimulated, and the quantity of the vapor | steam derived | led-out by the extraction flow path can be reduced further.

本発明に係る湯沸し器の更なる特徴構成は、上面視における前記湯沸し器の前後方向において、前方側に前記注ぎ口を設け、後方側に把手を設け、
前記水平向き流路が、前記前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路を備え、
前記水平向き分岐流路及び前記下方向き流路が、前記弁機構の一部の上方側に位置し、
前記下方向き流路の下流側端部に開口形成された前記蒸気導出口が、前記弁機構の一部に対して上下方向で隙間を形成する状態で、前記注出流路における前記弁機構の下流側に開口する点にある。 A further characteristic configuration of the water heater according to the present invention is that, in the front-rear direction of the water heater in a top view, the spout is provided on the front side, and a handle is provided on the rear side.
The horizontal flow path is disposed along the front-rear direction, and includes a horizontal branch flow path that branches at least in the left-right direction with respect to the front-rear direction,
The horizontal branch flow path and the downward flow path are located above a part of the valve mechanism,
The steam outlet opening formed at the downstream end of the downward channel forms a gap in the vertical direction with respect to a part of the valve mechanism. The point is that it opens downstream.

上記特徴構成によれば、水平向き流路が前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路を備え、水平向き分岐流路及び下方向き流路が、注出流路を開閉自在な弁機構の一部の上方側に位置するので、弁機構の開閉により貯留部内の液体の注ぎ口を介する通流を良好に制御できながら、弁機構の一部と蒸気流路の水平向き分岐流路及び下方向き流路とを上下方向に重ねて配置して上下方向におけるコンパクト化を図ることができる。
また、下方向き流路の下流側端部に開口形成された蒸気導出口が、弁機構の一部に対して上下方向で対向する状態で、注出流路における弁機構の下流側の部位に開口するので、蒸気導出口から注出流路における弁機構の下流側の部位に導出された蒸気が、弁機構の一部の上部に衝突して、当該蒸気の流速が低減されることとなる。
これにより、蒸気が注出流路内を通流する流速をより一層低下させることができ、当該蒸気の温度低下をより一層促進し結露を促進して、蒸気の量をより一層低減することができる。 According to the above characteristic configuration, the horizontal flow path is disposed along the front-rear direction, and the horizontal flow path branches at least in the left-right direction with respect to the front-rear direction. Since the direction flow path is located above a part of the valve mechanism that can open and close the discharge flow path, the flow through the liquid spout in the reservoir can be controlled well by opening and closing the valve mechanism. A part of the mechanism and the horizontal branch flow path and the downward flow path of the steam flow path are arranged so as to overlap each other in the vertical direction, so that the compactness in the vertical direction can be achieved.
In addition, the steam outlet opening formed at the downstream end of the downward flow path is opposed to a part of the valve mechanism in the up-down direction, and the downstream part of the valve mechanism in the discharge flow path Since the opening is made, the steam led out from the steam outlet to the downstream part of the valve mechanism in the discharge channel collides with a part of the upper part of the valve mechanism, and the flow velocity of the steam is reduced. .
As a result, the flow rate at which the steam flows through the extraction flow path can be further reduced, the temperature decrease of the steam can be further promoted, condensation can be promoted, and the amount of steam can be further reduced. it can.

蓋体６の内部には、内容器３を臨む連通空間３０と注ぎ口９を介して外部とを連通し、内容器３内の湯水を注ぎ口９を介して外部に通流させる注出流路３１と、注出流路３１に設けられ、注出流路３１を開閉自在な弁機構Ｖと、内容器３を臨む連通空間３０と注出流路３１における弁機構Ｖの下流側とを連通し、内容器３内の湯水から発生する蒸気を注出流路３１における弁機構Ｖの下流側に通流させる蒸気流路３２とが形成されている。   The inside of the lid 6 communicates the communication space 30 facing the inner container 3 with the outside through the spout 9, and the pouring flow for flowing hot water in the inner container 3 to the outside through the spout 9. A passage 31, a valve mechanism V provided in the extraction flow path 31 and capable of opening and closing the extraction flow path 31; a communication space 30 facing the inner container 3; and a downstream side of the valve mechanism V in the extraction flow path 31.

The weight body 33 is housed in a valve housing portion (not shown) formed in the lid body member 20 so as to be recessed downward. Therefore, even if the container body 4 falls, the two weights 33 move in the valve housing portion so as to close the steam inlets 32A and 32B of the steam channel 32 and are accommodated in the inner container 3. Inflow of hot water into the steam flow path 32 is prevented. In addition, a positioning rib 20b that protrudes upward in a state of surrounding the entire periphery is formed on the outer peripheral edge portion of the valve housing portion that is formed in a substantially rectangular shape on the upper surface of the lid body member 20 when viewed from above. (See FIG. 4).

By being attached to the upper surface, the steam channel 32 extends in the horizontal direction and communicates with the inner container 3 via the steam inlets 32A and 32B, and the lower side from the horizontal channel 60. And a downward-facing flow path 61 that communicates with the extraction flow path 31 via a steam outlet 32C formed at the downstream end (see FIGS. 6, 8, and 9). ).

なお、上面視で、蓋本体部材２０の上面において円盤状本体２５ｂの上部に対応する箇所には、当該蓋本体部材２０を上下方向に貫通する一対の貫通孔２０ｃが形成されている。この一対の貫通孔２０ｃは、蓋本体部材２０において、弁軸２５ａと把手８とを結ぶ方向（前後方向）に対して左右方向で同一距離にある箇所の夫々に貫通形成され、当該一対の貫通孔２０ｃの上部周縁部の夫々には上方に突出する円形リブ（図示せず）が形成されている。当該円形リブが後述する流路形成部材４０の各水平向き分岐流路６０ｂの導出用下方向き流路６１Ａにおける下流側端部に形成された開口部６１ａの夫々に内嵌された状態で、一対の貫通孔２０ｃが当該開口部６１ａに連通するように構成されており、当該一対の貫通孔２０ｃが蒸気流路３２の導出用蒸気流路の下流側端部に形成された蒸気導出口３２Ｃとして機能する。 The valve mechanism V includes a valve seat 20 a provided on the lid body member 20, a valve body 25 that prevents outflow of hot water while being in contact with the valve seat 20 a, and the valve body 25 as an upper surface of the inner lid plate 22. And a spring 27 that urges toward the closed state (upper side), and the valve body 25 of the valve mechanism V moves in the vertical direction so that the valve body 25 and the valve seat 20a come into contact with each other. By being separated, the extraction flow path 31 is configured to be openable and closable. Specifically, the valve body 25 includes a valve shaft 25a extending in the up-down direction, a disk-shaped main body 25b extending in a generally disk shape radially outward at a lower portion of the valve shaft 25a, And a spring mounting portion 25c extending in a cylindrical shape from the lower surface of the disk-shaped main body 25b. The spring 27 is mounted between the spring mounting portion 25c and the upper surface of the inner lid plate 22, and the valve shaft 25a is moved in the vertical direction so that the upper surface of the disc-shaped main body 25b and the valve seat 20a are brought into contact with or separated from each other. The pouring channel 31 is configured to be openable and closable.
In addition, a pair of through holes 20c penetrating the lid main body member 20 in the vertical direction is formed at a position corresponding to the upper portion of the disc-shaped main body 25b on the upper surface of the lid main body member 20 when viewed from above. The pair of through-holes 20c are formed in the lid main body member 20 so as to penetrate each of the portions that are at the same distance in the left-right direction with respect to the direction connecting the valve shaft 25a and the handle 8 (front-rear direction).

Function.

弁操作具２６は、注ぎ口９と把手８との間に設けられ、主として第１操作具２６Ａ及び第２操作具２６Ｂを備える。
第１操作具２６Ａは、一端側（前後方向における後側）が蓋カバー２１の上面から露出し、他端側（前後方向における前側）が蓋カバー２１内に収容されており、一端側及び他端側が左右方向に延びる揺動軸２６ａ周りで上下方向に揺動するように構成されている。
第２操作具２６Ｂは、蓋カバー２１内において、一端側（前後方向における後側）の下部が第１操作具２６Ａの他端側の上部と係合し、他端側（前後方向における前側）が弁機構Ｖの弁体２５の弁軸２５ａの上端の上方に位置するように構成されている。第２操作具２６Ｂは、ばね部材２６Ｃにより、一端側が下方側に、他端側が上方側に付勢されており、これに伴って、第２操作具２６Ｂの一端側に係合する第１操作具２６Ａも、一端側が上方側に、他端側が下方側に付勢されている。 The valve operating tool 26 is provided between the spout 9 and the handle 8 and mainly includes a first operating tool 26A and a second operating tool 26B.
One end side (rear side in the front-rear direction) of the first operation tool 26A is exposed from the upper surface of the lid cover 21, and the other end side (front side in the front-rear direction) is accommodated in the lid cover 21. The end side is configured to swing up and down around a swing shaft 26a extending in the left-right direction.
The second operation tool 26B has a lower end on one end side (rear side in the front-rear direction) engaged with an upper part on the other end side of the first operation tool 26A, and the other end side (front side in the front-rear direction). Is configured to be located above the upper end of the valve shaft 25a of the valve body 25 of the valve mechanism V. The second operation tool 26B is biased by the spring member 26C at one end side downward and the other end side upward, and accordingly, the first operation is engaged with one end side of the second operation tool 26B. The tool 26A is also urged with one end side upward and the other end side downward.

従って、弁操作具２６を操作しない自然状態では、ばね部材２６Ｃの付勢力により、第２操作具２６Ｂの他端側は弁体２５の弁軸２５ａに当接せず、弁機構Ｖの弁体２５の円盤状本体２５ｂの上面は弁座２０ａと当接したままとなり、注出流路３１は閉鎖された状態となる。この閉鎖状態では、ケトル本体２を傾けても、注ぎ口９から内容器３内の湯水が漏出することはない。
一方で、第１操作具２６Ａの一端側をばね部材２６Ｃの付勢力に抗して下方側に押圧することにより、第２操作具２６Ｂの他端側が下方側に移動して弁体２５の弁軸２５ａの上端を下方側に押圧移動させ、弁体２５の円盤状本体２５ｂの上面が弁座２０ａから離間して、注出流路３１は開放された状態となる。この開放状態で、注ぎ口９が下側となるように傾けることにより、内容器３内の湯水を注ぎ口９を介して外部に通流させることができる。 Therefore, in a natural state where the valve operating tool 26 is not operated, the other end side of the second operating tool 26B does not contact the valve shaft 25a of the valve body 25 due to the biasing force of the spring member 26C, and the valve body of the valve mechanism V The upper surface of the disc-shaped main body 25b of 25 remains in contact with the valve seat 20a, and the dispensing flow path 31 is closed. In this closed state, even if the kettle body 2 is tilted, hot water in the inner container 3 does not leak from the spout 9.
On the other hand, by pressing one end of the first operating tool 26A downward against the urging force of the spring member 26C, the other end of the second operating tool 26B moves downward and the valve of the valve body 25 The upper end of the shaft 25a is pressed and moved downward, the upper surface of the disc-like main body 25b of the valve body 25 is separated from the valve seat 20a, and the dispensing flow path 31 is opened. By tilting so that the pouring spout 9 is on the lower side in this open state, the hot water in the inner container 3 can be allowed to flow outside through the pouring spout 9.

次に、図２〜図９に基づいて、本願の特徴的構成である蒸気流路３２について説明する。

Inside the member 40, a flow path in which only the steam inlets 32A and 32B and the opening 61a are opened is formed.

具体的には、図４、図６及び図７に示すように、蒸気流路形成部材４０内には、主として上部材４１の突出内壁４１ｃの内側及び板状部材と、下部材４２の突出内壁４２ｃの内側及び板状部材と、パッキン部材４４の嵌合部４４ｂの底部及び貫通孔４４ｃの内周面と、温度検知具４３のキャップ４３ａの底壁部とにより囲繞される水平向き空間が形成される。この水平向き空間は、前後方向（水平方向）に沿って延出し、蒸気導入口３２Ａ、３２Ｂから導入された蒸気の温度を検知する温度検知具４３が配設され、蒸気導入口３２Ａ、３２Ｂを介して連通空間３０に連通する検知用水平向き流路６０Ａとして機能する。検知用水平向き流路６０Ａは、前後方向に沿う略直線状流路として形成され、当該直線状流路において蒸気導入口３２Ｂ、３２Ａと温度検知具４３とが上流側から下流側（前側から後側）に向かって記載順に配設されている。なお、検知用水平向き流路６０Ａの下流側は、温度検知具４３のキャップ４３ａにより閉鎖されている。   Specifically, as shown in FIGS. 4, 6, and 7, the steam flow path forming member 40 mainly includes an inner side of the protruding inner wall 41 c of the upper member 41 and a plate-like member, and a protruding inner wall of the lower member 42. A horizontal space surrounded by the inner side of 42c and the plate-like member, the bottom of the fitting portion 44b of the packing member 44 and the inner peripheral surface of the through hole 44c, and the bottom wall of the cap 43a of the temperature detector 43 is formed. Is done. The horizontal space extends in the front-rear direction (horizontal direction), and a temperature detector 43 that detects the temperature of the steam introduced from the steam inlets 32A and 32B is disposed, and the steam inlets 32A and 32B are connected to each other. It functions as a horizontal flow path for detection 60 </ b> A communicating with the communication space 30. The detection-oriented horizontal channel 60A is formed as a substantially linear channel along the front-rear direction, and the steam inlets 32B, 32A and the temperature detector 43 are connected from the upstream side to the downstream side (from the front side to the rear side). Are arranged in the order of description. The downstream side of the detection-oriented horizontal flow path 60 </ b> A is closed by a cap 43 a of the temperature detection tool 43.

また、蒸気流路形成部材４０内には、主として上部材４１の突出内壁４１ｃの外側及び突出外壁４１ａの内側及び板状部材と、下部材４２の突出内壁４２ｃの外側及び突出外壁４２ａの内側及び板状部材と、パッキン部材４４の嵌合部４４ｂの底部とにより囲繞される水平向き空間が形成される。この水平向き空間は、略前後方向（水平方向）に沿って延出し、検知用水平向き流路６０Ａと連通する導出用水平向き流路６０Ｂとして機能する。   Further, in the steam flow path forming member 40, mainly the outer side of the protruding inner wall 41c of the upper member 41 and the inner side of the protruding outer wall 41a and the plate-like member, the outer side of the protruding inner wall 42c of the lower member 42 and the inner side of the protruding outer wall 42a and A horizontally oriented space surrounded by the plate member and the bottom of the fitting portion 44b of the packing member 44 is formed. This horizontal space extends substantially along the front-rear direction (horizontal direction) and functions as a derivation horizontal flow channel 60B communicating with the detection horizontal flow channel 60A.

検知用水平向き流路６０Ａと導出用水平向き流路６０Ｂとは接続部６２を介して接続されており、接続部６２は、検知用水平向き流路６０Ａの直線状流路における蒸気導入口３２Ａ、３２Ｂの下流側で且つ温度検知具４３の上流側の箇所と導出用水平向き流路６０Ｂとが接続される箇所に形成されている。この接続部６２は、上述の上部材４１の突出内壁４１ｃにおける開口部４１ｄを形成する端部のうち他端側（下面視で、前後方向に沿って後側から前側に向かって右側）の端部が、開口部４１ｂの左右方向における中央部近傍に向かって延出し、開口部４１ｂを形成する突出外壁４１ａの両端部（下面視で、前後方向に沿って後側から前側に向かって右側及び左側の端部）よりも注ぎ口９側に引退した位置にまで延出されていること、及び、下部材４２の突出内壁４２ｃにおける開口部４２ｄを形成する端部のうち他端側（上面視で、前後方向に沿って後側から前側に向かって左側）の端部が、開口部４２ｂの左右方向における中央部近傍に向かって延出し、開口部４２ｂを形成する突出外壁４２ａの両端部（上面視で、前後方向に沿って後側から前側に向かって右側及び左側の端部）よりも注ぎ口９側に引退した位置にまで延出されていることにより、所定の流路断面積（図６及び図８では流路断面積Ｂで示す）を備えるように連通形成されている。なお、当該接続部６２は、開口部６０ａがパッキン部材４４の嵌合部４４ａ等により密着状態で閉鎖されるが、嵌合部４４ａの底部とこれら他端側の両端部との間には所定の隙間が形成されており、所定の流路断面積（図６及び図８では流路断面積Ｂで示す）となるように構成されている。   The detection horizontal flow path 60A and the derivation horizontal flow path 60B are connected via a connecting portion 62, and the connection portion 62 is a steam inlet 32A in the linear flow path of the detection horizontal flow path 60A. , 32B and the upstream side of the temperature detector 43 and the outlet horizontal flow path 60B are connected to each other. This connecting portion 62 is the end on the other end side (the right side from the rear side to the front side in the front-rear direction in the bottom view) of the end portion that forms the opening 41d in the protruding inner wall 41c of the upper member 41 described above. Part extends toward the vicinity of the central portion in the left-right direction of the opening 41b, and both ends of the projecting outer wall 41a forming the opening 41b (on the right side from the rear side to the front side in the front-rear direction in the bottom view) It extends to a position retreated to the spout 9 side from the left end portion, and the other end side (viewed from above) of the end portion forming the opening 42d in the protruding inner wall 42c of the lower member 42. Thus, the end portions on the left side from the rear side to the front side along the front-rear direction extend toward the vicinity of the central portion in the left-right direction of the opening 42b, and both end portions of the protruding outer wall 42a forming the opening 42b ( Back along the front-rear direction in top view Is extended to a position retracted from the right side and the left side toward the front side toward the spout 9 side, so that a predetermined channel cross-sectional area (the channel cross-sectional area B in FIGS. 6 and 8). The communication is formed so as to include. In addition, although the opening part 60a is closed in a close contact state by the fitting part 44a of the packing member 44 or the like, the connection part 62 has a predetermined gap between the bottom part of the fitting part 44a and both end parts on the other end side. Are formed so as to have a predetermined channel cross-sectional area (indicated by a channel cross-sectional area B in FIGS. 6 and 8).

検知用水平向き流路６０Ａと導出用水平向き流路６０Ｂとは、接続部６２により相互に１８０度程度屈曲した状態で接続されている。即ち、検知用水平向き流路６０Ａでは、蒸気が前後方向における前側から後側に向かって通流し、その後、接続部６２により略１８０度Ｕターンして導出用水平向き流路６０Ｂに流入し、導出用水平向き流路６０Ｂでは、前後方向における後側から前側に向かって通流するように構成されている。   The detection horizontal channel 60 </ b> A and the derivation horizontal channel 60 </ b> B are connected to each other in a state of being bent by about 180 degrees by the connection part 62. That is, in the detection horizontal flow path 60A, the steam flows from the front side to the rear side in the front-rear direction, and then flows approximately 180 degrees U-turn through the connection portion 62 and flows into the derivation horizontal flow path 60B. The derivation horizontal flow path 60B is configured to flow from the rear side to the front side in the front-rear direction.

従って、蒸気流路形成部材４０の開口部形成筒部４０Ａ及び幅広部４０Ｂにおいては、検知用水平向き流路６０Ａと導出用水平向き流路６０Ｂとは接続部６２により接続されることで概略のの字形状に形成され、導出用水平向き流路６０Ｂが検知用水平向き流路６０Ａの左右側に配置されることとなる。なお、上面視で、前後方向における後側から前側に向かって右側の導出用水平向き流路６０Ｂ（概略のの字形状の行き止まり部分）は閉塞空間６０Ｃとなるように形成されており、閉鎖空間６０Ｃ内に流入した蒸気の通流を阻害して流速を低下できるとともに、蒸気が閉鎖空間６０Ｃに滞留して、蒸気の温度低下を促進して結露を促進することができるように構成されている。   Therefore, in the opening forming cylinder portion 40A and the wide portion 40B of the steam flow path forming member 40, the detection horizontal direction flow path 60A and the derivation horizontal direction flow path 60B are connected by the connecting portion 62. The lead-out horizontal channel 60B is disposed on the left and right sides of the detection horizontal channel 60A. In addition, when viewed from the top, the right-side lead-out horizontal flow path 60B from the rear side to the front side in the front-rear direction (schematic square-shaped dead end portion) is formed to be a closed space 60C, and is a closed space. The flow of steam that has flowed into the 60C can be inhibited and the flow rate can be reduced, and the steam can be retained in the closed space 60C to promote the temperature drop of the steam and promote condensation. .

蒸気流路形成部材４０の筒部４０Ｃにおいては、導出用水平向き流路６０Ｂは略直線状流路として形成され、その後、二股分岐部４０Ｄにおいては、導出用水平向き流路６０Ｂは、筒部４０Ｃから斜め前方向（前後方向に対して左右方向にそれぞれ４５度程度傾斜する方向）に分岐する水平向き分岐流路６０ｂとして機能するように形成される。なお、二股分岐部４０Ｄにおける注ぎ口９側の突出外壁４１ａ及び突出外壁４２ａの外側は、弁体２５の弁軸２５ａを囲繞するように概略円弧状に形成されている。従って、各水平向き分岐流路６０ｂは、上面視で、弁機構Ｖの弁体２５の弁軸２５ａの径方向外方に形成された円盤状本体２５ｂの上方側に位置するとともに、注出流路３１における弁機構Ｖの下流側の部位の上方側に位置することとなる。即ち、各水平向き流路６０ｂは、円盤状本体２５ｂ及び当該円盤状本体２５ｂの下流側（上方側）の注出流路３１の一部に対して、上下方向で重なる位置に設けられていることとなる。   In the cylinder part 40C of the steam flow path forming member 40, the derivation horizontal flow path 60B is formed as a substantially straight flow path, and then, in the bifurcated branch part 40D, the derivation horizontal flow path 60B is formed of a cylinder part. It is formed so as to function as a horizontal branch flow path 60b that branches obliquely forward from 40C (a direction inclined by about 45 degrees in the left-right direction with respect to the front-rear direction). In addition, the outer side of the protruding outer wall 41a and the protruding outer wall 42a on the spout 9 side in the bifurcated branching portion 40D is formed in a substantially arc shape so as to surround the valve shaft 25a of the valve body 25. Accordingly, each horizontal branch flow path 60b is located above the disk-shaped main body 25b formed radially outward of the valve shaft 25a of the valve body 25 of the valve mechanism V in a top view, and is poured out. It will be located above the downstream side of the valve mechanism V in the passage 31. That is, each horizontal flow path 60b is provided at a position overlapping in the vertical direction with respect to the disc-shaped main body 25b and a part of the extraction flow path 31 on the downstream side (upper side) of the disc-shaped main body 25b. It will be.

また、蒸気流路形成部材４０内には、主として、下部材４２の一対の管部４２ｅの内壁面により囲繞される下方向き空間が形成される。この下方向き空間は、略上下方向（鉛直方向）に沿って延出し、水平向き分岐流路６０ｂのそれぞれの下流側端部から下方側に延出し、下流側端部に開口部６１ａを備え、当該開口部６１ａ及び蒸気導出口３２Ｃを介して注出流路３１に連通する導出用下方向き流路６１Ａの一部として機能する。なお、導出用下向き流路６１Ａの他部は、蓋本体部材２０の上面に貫通形成された一対の貫通孔２０ｃにより構成され、当該貫通孔２０ｃが蒸気導出口２０Ｃとして機能する。各導出用下方向き流路６１Ａは、上面視で、前後方向に対して左右方向で最も離間した端部位置のそれぞれから延出形成されている。各導出用下方向き流路６１Ａは、弁機構Ｖの弁体２５の弁軸２５ａの径方向外方に形成された円盤状本体２５ｂの上方側に位置するとともに、注出流路３１における弁機構Ｖの下流側の部位の上方側に位置することとなる。即ち、各導出用下方向き流路６１Ａは、円盤状本体２５ｂ及び当該円盤状本体２５ｂの下流側（上方側）の注出流路３１の一部に対して、上下方向で重なる位置に設けられていることとなる。
また、各導出用下方向き流路６１Ａの下流側端部に設けられた開口部６１ａ及び蓋本体部材２０に設けられた一対の貫通孔２０ｃ（蒸気導出口３２Ｃ）は、弁機構Ｖの弁体２５の円盤状本体２５ｂ及び弁座２０ａに対して上下方向に対向する状態で、注出流路３１における弁機構Ｖの上流側（上方側）の部位に開口される。なお、本実施形態では、各導出用下方向き流路６１Ａは、水平向き分岐流路６０ｂ（水平方向）に対して略９０度屈曲するように垂直方向（鉛直下方）に延出するように形成されているが、この屈曲角度は、例えば、±３０度程度の範囲内で適宜調整することも可能である。また、水平向き分岐流路６０ｂの角度を水平方向に対して若干程度（例えば、±１０度程度傾斜）させることもできる。 Further, a downward space surrounded by the inner wall surfaces of the pair of pipe portions 42 e of the lower member 42 is mainly formed in the steam flow path forming member 40. This downward facing space extends substantially along the vertical direction (vertical direction), extends downward from each downstream end of the horizontal branch flow path 60b, and has an opening 61a at the downstream end, It functions as a part of the downward flow path 61A for extraction that communicates with the extraction flow path 31 via the opening 61a and the steam outlet 32C. The other part of the outlet downward channel 61A is constituted by a pair of through holes 20c formed through the upper surface of the lid body member 20, and the through holes 20c function as the vapor outlet 20C. Each lead-out downward flow path 61A is formed to extend from each of the end positions that are farthest in the left-right direction with respect to the front-rear direction when viewed from above. Each lead-out downward flow path 61A is positioned above the disc-shaped main body 25b formed radially outward of the valve shaft 25a of the valve body 25 of the valve mechanism V, and the valve mechanism in the dispensing flow path 31. It will be located above the downstream site of V. In other words, each of the derivation downward flow paths 61A is provided at a position overlapping the disk-shaped main body 25b and a part of the extraction flow path 31 on the downstream side (upper side) of the disk-shaped main body 25b in the vertical direction. Will be.
In addition, the opening 61a provided at the downstream end of each downward flow passage 61A and the pair of through holes 20c (steam outlet 32C) provided in the lid main body member 20 are provided in the valve body of the valve mechanism V. In the state which opposes the disk-shaped main body 25b of 25 and the valve seat 20a to an up-down direction, it opens to the site | part of the upstream (upper side) of the valve mechanism V in the extraction flow path 31. FIG. In the present embodiment, each of the derivation downward channel 61A is formed to extend in the vertical direction (vertically downward) so as to be bent approximately 90 degrees with respect to the horizontal branch channel 60b (horizontal direction). However, the bending angle can be appropriately adjusted, for example, within a range of about ± 30 degrees. In addition, the angle of the horizontal branch flow path 60b can be slightly increased (for example, inclined by about ± 10 degrees) with respect to the horizontal direction.

ここで、上記のように構成された検知用水平向き流路６０Ａ及び導出用水平向き流路６０Ｂを備えた水平向き流路６０と、下方向き流路６１と、水平向き流路６０と下方向き流路６１とを接続する接続部６２とにより、蒸気流路３２の一部が形成されるが、図６〜図８に示すように、接続部６２の流路断面積Ｂは、検知用水平向き流路６０Ａの流路断面積Ｃよりも小さな流路断面積の狭部として機能するように形成されている。また、下方向き流路６１の流路断面積Ａは、蒸気流路３２の流路断面積（検知用水平向き流路６０Ａの流路断面積Ａ、導出用水平向き流路６０Ｂの流路断面積（図示せず）、接続部６２の流路断面積Ｂなど）よりも小さな流路断面積の絞り部として機能するように形成されている。   Here, the horizontal flow channel 60 including the detection horizontal flow channel 60A and the derivation horizontal flow channel 60B configured as described above, the downward flow channel 61, the horizontal flow channel 60, and the downward flow. A part of the steam flow path 32 is formed by the connection portion 62 that connects the flow path 61. As shown in FIGS. It is formed so as to function as a narrow portion of a channel cross-sectional area smaller than the channel cross-sectional area C of the direction channel 60A. Further, the channel cross-sectional area A of the downward channel 61 is the channel cross-sectional area of the steam channel 32 (the channel cross-sectional area A of the detection horizontal channel 60A, the channel cross-section of the derivation horizontal channel 60B). It is formed so as to function as a throttle portion having a channel cross-sectional area smaller than an area (not shown) and a channel cross-sectional area B of the connecting portion 62.

次に、上記のように構成された電気ケトルを用いて、内容器３内の湯水を加熱して、蒸気が蒸気流路３２を通流する際の状態について説明する。   Next, the state when steam flows through the steam flow path 32 by heating the hot water in the inner container 3 using the electric kettle configured as described above will be described.

ユーザが、ケトル本体２を電源プレート１上に載置し、内容器３内の湯水を加熱するために操作部１０の湯沸し用の運転スイッチ１０Ａを押圧すると、給電機構１Ａから受電機構２Ａを介して電熱ヒータ５に電力が供給され、電熱ヒータ５により内容器３内の湯水が加熱される。
当該加熱に伴って内容器３内の湯水から蒸気が発生すると、当該蒸気は順次上昇して内蓋板２２に貫通形成された蒸気流通孔を介して連通空間３０内に導入され、蒸気流路３２を通流することとなる。即ち、当該蒸気は、蒸気流通孔、連通空間３０、転倒止水弁Ｑ、蒸気導入口３２Ａ、３２Ｂ、水平向き流路６０（検知用水平向き流路６０Ａ、接続部６２、導出用水平向き流路６０Ｂ（水平向き分岐流路６０ｂを含む）、下方向き流路６１、蒸気導出口３２Ｃの順に通流し、注出流路３１内に導出される。 When the user places the kettle body 2 on the power supply plate 1 and presses the operation switch 10A for boiling water of the operation unit 10 to heat the hot water in the inner container 3, the power feeding mechanism 1A through the power receiving mechanism 2A. Then, electric power is supplied to the electric heater 5, and the hot water in the inner container 3 is heated by the electric heater 5.
When steam is generated from the hot water in the inner container 3 with the heating, the steam rises sequentially and is introduced into the communication space 30 through a steam flow hole formed in the inner lid plate 22 so as to penetrate the steam flow path. 32 will flow. That is, the steam flows through the steam flow hole, the communication space 30, the overturn stop valve Q, the steam inlets 32A and 32B, the horizontal flow path 60 (the horizontal flow path for detection 60A, the connecting portion 62, the horizontal flow for derivation. The path 60B (including the horizontal branch flow path 60b), the downward flow path 61, and the steam outlet 32C flow in this order and are led into the extraction flow path 31.

この際、蓋体６の内部に、内容器３と外部とを連通し、内容器３内の湯水を注ぎ口９を介して外部に通流させる注出流路３１と、注出流路３１に設けられ、注出流路３１を開閉自在な弁機構Ｖと、内容器３と注出流路３１における弁機構Ｖの下流側とを連通し、内容器３内の湯水から発生する蒸気を注出流路３１における弁機構Ｖの下流側に通流させる蒸気流路３２とを備えているので、電熱ヒータ５による内容器３内の湯水の加熱により内容器３内にて発生した蒸気を、比較的長い流路となる内容器３、蒸気流路３２、注出流路３１、注ぎ口９の順に通流させ順次温度を低下させて、蒸気流路３２及び注出流路３１内で結露させることができ、注ぎ口９から排出される蒸気の量をある程度低減することができる。この際、蓋体６の上面に蒸気口を開口形成する必要がないので、蓋体６の上面から蒸気が排出されることが無く、子供等が蒸気に触れる可能性を低減することができる。   At this time, the inside of the lid 6 is connected to the inner container 3 and the outside, and a pouring channel 31 for allowing the hot water in the inner container 3 to flow to the outside through the spout 9, and the pouring channel 31. The steam generated from the hot water in the inner container 3 is communicated with the valve mechanism V that can freely open and close the pouring flow path 31 and the inner container 3 and the downstream side of the valve mechanism V in the pouring flow path 31. Since the steam flow path 32 is provided in the extraction flow path 31 to the downstream side of the valve mechanism V, steam generated in the inner container 3 due to heating of the hot water in the inner container 3 by the electric heater 5 is supplied. The inner vessel 3, the steam channel 32, the pouring channel 31, and the spout 9 that are relatively long channels are passed through in this order to lower the temperature in order, and in the steam channel 32 and the pouring channel 31. Condensation can be performed, and the amount of steam discharged from the spout 9 can be reduced to some extent. At this time, since it is not necessary to form a steam port on the upper surface of the lid body 6, the steam is not discharged from the upper surface of the lid body 6, and the possibility that a child or the like touches the steam can be reduced.

特に、蒸気流路３２が、水平方向に延出し、蒸気導入口３２Ｃを介して内容器３に連通する水平向き流路６０と、水平向き流路６０から下方側に延出し、下流側端部に形成された蒸気導出口３２Ｃを介して注出流路３１における弁機構Ｖの下流側に連通する下方向き流路６１とを備えているので、内容器３内で発生した蒸気は上昇して、まず、蒸気導入口３２Ａ、３２Ｂを介して水平向き流路６０内を通流し、その後、水平向き流路６０から下方側に延出し且つ当該水平向き流路６０の下流側に位置する下方向き流路６１内を通流して、下方向き流路６１の下流側端部に形成された蒸気導出口３２Ｃを介して注出流路３１内を通流し、注ぎ口９に到達することとなる。
従って、蒸気導入口３２Ａ、３２Ｂから導入され水平向き流路６０内を水平方向に沿って通流する蒸気は、下方向き流路６１に導入される際に当該下方向き流路６１内を下方向に沿って通流するように強制的に方向変換させられるため、下方向き流路６１の入り口付近である程度の蒸気の滞留が発生する。即ち、蒸気が下方向き流路６１に導入される際には、比較的高温の蒸気が上昇しようとする方向（上方向）とは反対側の下方向に強制的に方向変換させられるので、当該蒸気の流速を良好に弱めることができるのである。
これにより、下方向き流路６１内を通流する蒸気の流速は比較的低下した状態となり、蒸気が水平向き流路６０及び下方向き流路６１内を通流する流速を低下させることができ、当該蒸気の温度低下を促進し結露を促進させることができる。更に、当該蒸気を、下方向き流路６１の下流側端部に形成された蒸気導出口３２Ｃを介して注出流路３１内に導出し、注ぎ口９を介して外部に排出するので、注ぎ口９から排出される蒸気を低減することができる。
よって、子供等が蒸気に触れる可能性を低減することができ、また、外部（室内）の湿度の上昇も低減することができる。 In particular, the steam flow path 32 extends in the horizontal direction and communicates with the inner container 3 via the steam inlet 32C, and extends downward from the horizontal flow path 60 to the downstream end. The steam generated in the inner container 3 rises with the downward-facing channel 61 communicating with the downstream side of the valve mechanism V in the extraction channel 31 via the steam outlet 32C formed in First, it flows through the horizontal channel 60 through the steam inlets 32 </ b> A and 32 </ b> B, and then extends downward from the horizontal channel 60 and is located downstream of the horizontal channel 60. It flows through the flow path 61, flows through the pour-out flow path 31 through the steam outlet 32 </ b> C formed at the downstream end of the downward flow path 61, and reaches the spout 9.
Therefore, when the steam introduced from the steam inlets 32A and 32B and flowing through the horizontal channel 60 along the horizontal direction is introduced into the downward channel 61, the steam flows downward in the downward channel 61. Since the direction is forcibly changed so as to flow along the flow path, a certain amount of vapor stays near the entrance of the downward flow path 61. That is, when the steam is introduced into the downward flow path 61, the direction is forced to be changed in the downward direction opposite to the direction in which the relatively high-temperature steam is going to rise (upward direction). The steam flow rate can be satisfactorily reduced.
Thereby, the flow rate of the steam flowing through the downward flow path 61 is relatively lowered, and the flow rate of the steam flowing through the horizontal flow path 60 and the downward flow path 61 can be reduced. Condensation can be promoted by promoting the temperature drop of the steam. Further, since the steam is led out into the pouring channel 31 through the steam outlet 32C formed at the downstream end of the downward channel 61 and discharged to the outside through the pouring port 9, Steam discharged from the port 9 can be reduced.
Therefore, the possibility that children and the like will come into contact with steam can be reduced, and an increase in humidity outside the room (indoors) can also be reduced.

また、蓋体６の上下方向の厚みを利用して下方向き流路６１を形成することで、蒸気流路３２の水平向き流路６０を長くしなくても蒸気を低減することができるので、蓋体６内の水平方向における省スペース化及びコンパクト化を図ることができる。
蒸気流路３２における水平向き流路６０及び下方向き流路６１内で結露した結露水は、蒸気導出口３２Ｃを介して注出流路３１に戻すことができるので、蒸気流路３２内に結露水が滞留することは良好に防止されている。
よって、上述の下方向き流路６１を設けるという非常に簡便且つコンパクトな構成で、注ぎ口９から排出される蒸気の量を確実に低減することができる。 Further, by forming the downward flow path 61 using the vertical thickness of the lid 6, steam can be reduced without increasing the horizontal flow path 60 of the steam flow path 32. Space saving and compactness in the horizontal direction in the lid 6 can be achieved.
Since the dew condensation water condensed in the horizontal flow path 60 and the downward flow path 61 in the steam flow path 32 can be returned to the extraction flow path 31 via the vapor outlet 32C, the dew condensation is formed in the steam flow path 32. The retention of water is well prevented.
Therefore, the amount of steam discharged from the spout 9 can be reliably reduced with a very simple and compact configuration in which the downward flow path 61 is provided.

さらに、下方向き流路６１が水平向き流路６０の下流側端部から延出形成されるので、水平向き流路６０内から下方向き流路６１内へ通流する蒸気は、水平向き流路６０の下流側端部の壁面に衝突して水平方向から下方向に強制的に方向変換することとなり、当該蒸気の流速が確実に弱められた状態で、下方向き流路６１内を通流することとなる。
これにより、蒸気が水平向き流路６０及び下方向き流路６１内を通流する流速を一層低下させることができ、当該蒸気の温度低下を一層促進し結露を促進して、蒸気の量をより一層低減することができる。また、蒸気流路３２における水平向き流路６０及び下方向き流路６１内で結露した結露水は、水平向き流路６０の下流側端部に残留することなく、蒸気導出口３２Ｃを介して注出流路３１に戻すことができる。 Furthermore, since the downward flow path 61 is formed to extend from the downstream end of the horizontal flow path 60, the steam flowing from the horizontal flow path 60 into the downward flow path 61 It collides with the wall surface of the downstream end portion of 60 and forcibly changes its direction from the horizontal direction to the downward direction, and flows through the downward flow path 61 in a state where the flow velocity of the steam is surely weakened. It will be.
As a result, the flow rate of the steam flowing through the horizontal flow path 60 and the downward flow path 61 can be further reduced, further reducing the temperature of the steam and promoting condensation, thereby further increasing the amount of steam. Further reduction can be achieved. Further, the condensed water condensed in the horizontal channel 60 and the downward channel 61 in the steam channel 32 does not remain at the downstream end of the horizontal channel 60 and is injected through the steam outlet 32C. It can be returned to the outlet channel 31.

一方で、下方向き流路６１の流路断面積Ａが、蒸気流路３２の流路断面積（例えば、水平向き流路６０における流路断面積Ｂ及び流路断面積Ｃ）よりも小さな流路断面積の絞り部とされているので、当該絞り部を通流する蒸気の通流を阻害して、当該蒸気が通流する流速を低減することができ、当該絞り部よりも上流側の箇所（絞り部よりも上流側の下方向き流路６１及び水平向き流路６０）に蒸気をある程度滞留させることができる。
これにより、絞り部の上流側の箇所での蒸気の結露を促進し、注出流路３１に導出される蒸気の量をより一層低減することができる。 On the other hand, the flow path cross-sectional area A of the downward flow path 61 is smaller than the flow path cross-sectional area of the steam flow path 32 (for example, flow path cross-sectional area B and flow path cross-sectional area C in the horizontal flow path 60). Since it is the throttle section of the road cross-sectional area, it is possible to inhibit the flow of steam flowing through the throttle section, and to reduce the flow velocity through which the steam flows, and to the upstream side of the throttle section Steam can stay to some extent in the locations (downward flow path 61 and horizontal flow path 60 upstream of the throttle).
Thereby, the dew condensation of the vapor | steam in the location of the upstream of a throttle part can be accelerated | stimulated, and the quantity of the vapor | steam derived | led-out to the extraction flow path 31 can be reduced further.

また、水平向き流路６０の各水平向き分岐流路６０ｂ及び下方向き流路６１が、注出流路３１と上下方向で重なる位置に設けられているので、蓋体６内における上下方向及び水平方向のコンパクト性を確保した上で、水平向き流路６０及び下方向き流路６１の流路長を長くすることができる。
さらに、水平向き流路６０の各水平向き分岐流路６０ｂ及び下方向き流路６１が、注出流路３１を開閉自在な弁機構Ｖの弁体２５の円盤状本体２５ｂの下流側（上方側）に位置するので、弁機構Ｖの開閉により内容器３内の湯水の注ぎ口９を介する通流を良好に制御できながら、弁機構Ｖの弁体２５の円盤状本体２５ｂと蒸気流路２３の各水平向き分岐流路６０ｂ及び下方向き流路６１とを上下方向に重ねて配置して上下方向におけるコンパクト化を図ることができる。
また、下方向き流路６１の下流側端部に開口形成された蒸気導出口３２Ｃが、弁機構Ｖの弁体２５の円盤状本体２５ｂに対して上下方向で対向する状態で、注出流路３１における弁機構Ｖの下流側（上方側）の部位に開口するので、蒸気導出口３２Ｃから注出流路３１における当該円盤状本体２５ｂの下流側（上方側）の部位に導出された蒸気が、当該円盤状本体２５ｂの上部に衝突して、当該蒸気の流速が低減されることとなる。 In addition, since each horizontal branch flow path 60b and the downward flow path 61 of the horizontal flow path 60 are provided at positions that overlap the extraction flow path 31 in the vertical direction, the vertical direction and the horizontal direction in the lid body 6 are provided. The channel lengths of the horizontal channel 60 and the downward channel 61 can be increased while ensuring the compactness of the direction.
Furthermore, each horizontal branch flow path 60b and the downward flow path 61 of the horizontal flow path 60 are provided on the downstream side (upper side) of the disc-shaped body 25b of the valve body 25 of the valve mechanism V that can open and close the extraction flow path 31. ), The flow of the hot water in the inner container 3 through the spout 9 can be controlled well by opening and closing the valve mechanism V, while the disc-like main body 25b of the valve body 25 of the valve mechanism V and the steam channel 23 The horizontal branch flow paths 60b and the downward flow paths 61 are arranged so as to overlap each other in the vertical direction, so that downsizing in the vertical direction can be achieved.
In addition, in the state where the steam outlet 32C formed in the downstream end of the downward channel 61 is opposed to the disc-like body 25b of the valve body 25 of the valve mechanism V in the vertical direction, the extraction channel 31 opens to the downstream side (upper side) of the valve mechanism V, so that the steam led out from the steam outlet 32C to the downstream side (upper side) of the disc-shaped main body 25b in the extraction channel 31. Then, it collides with the upper part of the disk-shaped main body 25b, and the flow velocity of the steam is reduced.

よって、できるだけ簡便且つコンパクトな構成で、注ぎ口９から排出される蒸気の量を確実に低減することができる電気ケトルを提供できた。   Therefore, the electric kettle which can reduce reliably the quantity of the vapor | steam discharged | emitted from the spout 9 with the simple and compact structure as much as possible was able to be provided.

その後、水平向き流路６０の検知用水平向き流路６０Ａにおいて、蒸気導入口３２Ａ、３２Ｂから導入され温度検知具４３に導かれた蒸気の温度が検知され、温度検知具４３が所定の蒸気の温度を検知すると、内容器３内の湯水が所定の温度に到達しているものとして、制御部が電熱ヒータへの電力の供給を遮断する。   Thereafter, in the horizontal flow channel 60A for detection of the horizontal flow channel 60, the temperature of the steam introduced from the steam inlets 32A and 32B and guided to the temperature detector 43 is detected, and the temperature detector 43 detects the predetermined steam. When the temperature is detected, it is assumed that the hot water in the inner container 3 has reached a predetermined temperature, and the control unit cuts off the supply of electric power to the electric heater.

そして、内容器３内の湯水を注ぎ口９を介して外部に排出する際には、ユーザは把手８を把持しながら弁操作具２６を操作し、把手８に対して反対側に設けられた注ぎ口９側が下方となるように傾けることにより、内容器３内の湯水を注ぎ口９から外部に通流させることができる。   When the hot water in the inner container 3 is discharged to the outside through the spout 9, the user operates the valve operating tool 26 while holding the handle 8 and is provided on the opposite side to the handle 8. By tilting the pouring spout 9 side downward, the hot water in the inner container 3 can flow from the pouring spout 9 to the outside.

この際、注ぎ口９から通流する湯水と入れ換わるように、注ぎ口９を介して外部から注出流路３１内に空気が流入し、注ぎ口９から外部に通流する湯水の脈動（いわゆる息継ぎ）が発生する場合がある。
しかしながら、水平向き流路６０が前後方向に沿って配設されるとともに、当該前後方向に対して少なくとも左右方向に分岐する水平向き分岐流路６０ｂを備え、下方向き流路６１が水平向き分岐流路６０ｂのそれぞれから延出形成されるので、下方向き流路６１の下流側端部に複数の蒸気導出口３２Ｃを配置することができ、上述のように、注ぎ口９から外部に湯水を通流させる場合でも、蓋体６内の空気を複数の蒸気導出口３２Ｃの少なくとも一つから導入して、当該蒸気導出口３２Ｃ、蒸気流路３２の下方向き流路６１及び水平向き流路６０、更には蒸気導入口３２Ａ、３２Ｂを介して内容器３内に供給し、注ぎ口９から外部に通流する湯水の脈動（いわゆる息継ぎ）を良好に防止することができる。 At this time, air flows from the outside into the pouring channel 31 through the pouring spout 9 so as to replace the hot water flowing from the pouring spout 9, and the pulsation of hot water flowing from the spout 9 to the outside ( So-called breathing) may occur.
However, the horizontal flow path 60 is disposed along the front-rear direction, and includes a horizontal branch flow path 60b that branches at least in the left-right direction with respect to the front-rear direction, and the downward flow path 61 is a horizontal branch flow. Since it is formed extending from each of the channels 60b, a plurality of steam outlets 32C can be arranged at the downstream end of the downward channel 61, and hot water is passed from the spout 9 to the outside as described above. Even in the case of flowing, the air in the lid body 6 is introduced from at least one of the plurality of steam outlets 32C, the steam outlet 32C, the downward channel 61 of the steam channel 32, and the horizontal channel 60, Furthermore, pulsation (so-called breathing) of hot water that is supplied into the inner container 3 through the steam inlets 32A and 32B and flows from the spout 9 to the outside can be satisfactorily prevented.

また、ケトル本体２がテーブル等の上面で転倒した際には、ケトル本体２の前後方向がテーブルの上面と略平行で、ケトル本体２の左右方向がテーブルの上面に対して略垂直な状態となる。
この際、蒸気流路３２の水平向き流路６０内に結露水が滞留していると、当該結露水は、自重により、水平向き流路６０内においてテーブルの上面に対して垂直方向で最も近接する位置（下方側）に存在することとなる。即ち、当該結露水は、水平向き流路６０内においてケトル本体２の前後方向に対して左右方向で最も離間した端部位置に存在することとなる。
そして、下方向き流路６１が、水平向き分岐流路６０ｂにおいて、前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成されるので、ケトル本体２が転倒した際に水平向き流路６０内に滞留する結露水を確実に下方向き流路６１を介して注出流路３１に通流させることができ、水平向き流路６０内に結露水が滞留することは良好に防止されている。 Further, when the kettle body 2 falls on the upper surface of the table or the like, the front-rear direction of the kettle body 2 is substantially parallel to the upper surface of the table, and the left-right direction of the kettle body 2 is substantially perpendicular to the upper surface of the table. Become.
At this time, if the condensed water stays in the horizontal channel 60 of the steam channel 32, the condensed water is closest to the upper surface of the table in the horizontal channel 60 by its own weight in the vertical direction. It exists in the position (lower side) to do. That is, the dew condensation water is present in the end position farthest in the left-right direction with respect to the front-rear direction of the kettle body 2 in the horizontal channel 60.
And since the downward direction flow path 61 is extended and formed from each of the edge part position most spaced apart in the left-right direction with respect to the front-back direction in the horizontal direction branch flow path 60b, when the kettle main body 2 falls down, it is horizontal. Condensed water staying in the direction flow path 60 can be reliably passed through the discharge flow path 31 via the downward direction flow path 61, and it is favorable that the dew condensation water stays in the horizontal direction flow path 60. It is prevented.

〔別実施形態〕
（Ａ）上記実施形態では、図１０（ａ）に模式的に示すように、蒸気流路形成部材４０の二股分岐部４０Ｃ内に形成される一対の水平向き分岐流路６０ｂを、前後方向に対して左右方向にそれぞれ４５度程度傾斜するように斜め前方に直線状に延出形成し、下方向き流路６１を、各水平向き分岐流路６０ｂの下流側端部において前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成するように構成したが、例えば、下記（Ａ−１）〜（Ａ−６）に示すように、その他の構成に適宜変更することができる。 [Another embodiment]
(A) In the above embodiment, as schematically shown in FIG. 10 (a), the pair of horizontal branch channels 60b formed in the bifurcated branch section 40C of the steam channel forming member 40 are arranged in the front-rear direction. On the other hand, it is formed to linearly extend diagonally forward so as to incline about 45 degrees in the left-right direction, and the downward-facing flow channel 61 is formed to the left and right with respect to the front-rear direction at the downstream end of each horizontal branch flow channel 60b. Although it has been configured so as to extend from each of the end positions farthest in the direction, for example, as shown in the following (A-1) to (A-6), it can be appropriately changed to other configurations. .

（Ａ−１）例えば、図１０（ｂ）に模式的に示すように、一対の水平向き分岐流路６０ｂのそれぞれを概略Ｌ字形状に形成することもできる。即ち、一対の水平向き分岐流路６０ｂを、それぞれ左右方向に分岐させ、その後、前後方向の前側に延出するように構成し、下方向き流路６１を、各水平向き分岐流路６０ｂの下流側端部において前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成するように構成することもできる。 (A-1) For example, as schematically shown in FIG. 10B, each of the pair of horizontal branch channels 60b can be formed in a substantially L shape. That is, the pair of horizontal branch channels 60b is configured to branch in the left-right direction and then extend to the front side in the front-rear direction, and the downward channel 61 is provided downstream of each horizontal branch channel 60b. The side end portion can also be configured to extend from each of the end portion positions that are farthest in the left-right direction with respect to the front-rear direction.

（Ａ−２）例えば、図１０（ｃ）に模式的に示すように、一対の水平向き分岐流路６０ｂのそれぞれを概略円弧形状に形成し、下方向き流路６１を、各水平向き分岐流路６０ｂの下流側端部において前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成するように構成することもできる。 (A-2) For example, as schematically shown in FIG. 10 (c), each of the pair of horizontal branch channels 60b is formed in a substantially arc shape, and the downward channel 61 is connected to each horizontal branch flow. The downstream end portion of the path 60b may be configured to extend from each of the end portion positions that are the farthest in the left-right direction with respect to the front-rear direction.

（Ａ−３）例えば、図１０（ｄ）に模式的に示すように、一対の水平向き分岐流路６０ｂのそれぞれを概略円弧形状に形成し、下方向き流路６１を、各水平向き分岐流路６０ｂの下流側端部のそれぞれから延出形成させるが、各下方向き流路６１を、前後方向に対して左右方向で最も離間する端部位置から下方側に延出形成させる構成とせず、当該端部位置よりも左右方向で相互に近接する箇所にそれぞれ延出形成する構成とすることもできる。 (A-3) For example, as schematically shown in FIG. 10 (d), each of the pair of horizontal branch channels 60b is formed in a substantially circular arc shape, and the downward channel 61 is connected to each horizontal branch flow. Although it is formed to extend from each of the downstream side end portions of the path 60b, each downward-facing flow path 61 is not configured to extend downward from the end position that is farthest in the left-right direction with respect to the front-rear direction, It can also be set as the structure extended and formed in the location which mutually adjoins in the left-right direction rather than the said edge part position.

（Ａ−４）例えば、図１０（ｅ）に模式的に示すように、一対の水平向き分岐流路６０ｂのそれぞれを概略円弧形状に形成し、下方向き流路６１を、各水平向き分岐流路６０ｂの上流側端部と下流側端部との中間位置において前後方向に対して左右方向で最も離間する端部位置のそれぞれから延出形成するように構成することもできる。 (A-4) For example, as schematically shown in FIG. 10 (e), each of the pair of horizontal branch channels 60b is formed in a substantially arc shape, and the downward channel 61 is connected to each horizontal branch flow. It can also be configured to extend from each of the end positions farthest in the left-right direction with respect to the front-rear direction at an intermediate position between the upstream end and the downstream end of the path 60b.

（Ａ−５）例えば、図１０（ｆ）に模式的に示すように、一対の水平向き分岐流路６０ｂのそれぞれを概略円弧形状に形成し、下方向き流路６１の一方を、一方側の水平向き分岐流路６０ｂの上流側端部と下流側端部との中間位置において前後方向に対して右方向で最も離間する端部位置から延出形成し、下方向き流路６１の他方を、他方側の水平向き分岐流路６０ｂの上流側端部と下流側端部との間の上流側端部に近接する位置において前後方向に対して左右方向で最も離間する端部位置よりも左右方向で一方の下方向き流路６１に近接する箇所に延出形成する構成とすることもできる。 (A-5) For example, as schematically shown in FIG. 10 (f), each of the pair of horizontally-oriented branch flow paths 60b is formed in a substantially arc shape, and one of the downward-facing flow paths 61 is connected to one side. Extending and forming from the end position farthest rightward with respect to the front-rear direction at an intermediate position between the upstream end and the downstream end of the horizontal branch flow path 60b, the other of the downward flow path 61 is In the position close to the upstream end between the upstream end and the downstream end of the other horizontally oriented branch flow path 60b, the left and right direction is farther than the end position farthest in the left and right direction with respect to the front and rear direction. Thus, it may be configured to extend and form at a location close to one of the downward flow paths 61.

（Ａ−６）例えば、図示しないが、水平向き分岐流路６０ｂを一対設ける構成とするのではなく、左右方向の一方側のみに水平向き分岐流路６０ｂを設ける構成としてもよく、また、左右方向の両側のそれぞれに、単数又は複数の水平向き分岐流路６０ｂを設ける構成（例えば、右側に二つ、左側に二つ設ける構成）としてもよい。 (A-6) For example, although not shown, the horizontal branch flow path 60b may be provided only on one side in the left-right direction instead of the pair of horizontal branch flow paths 60b. It is good also as a structure (For example, the structure which provides two on the right side and two on the left side) which provides the horizontal direction flow path 60b of 1 or several horizontally on both sides of a direction.

（Ｂ）上記実施形態では、下方向き流路６１を、水平向き流路６０の流路断面積よりも小さな流路断面積の絞り部として形成したが、絞り部として形成する箇所を下方向き流路６１の一部分のみに形成してもよく、また、当該絞り部を省略する構成としてもよい。 (B) In the above embodiment, the downward flow path 61 is formed as a throttle portion having a flow path cross-sectional area smaller than that of the horizontal flow path 60. It may be formed only in a part of the path 61, and the throttle part may be omitted.

（Ｃ）上記実施形態では、導出用水平向き流路６０Ｂの一部（水平向き分岐流路６０ｂ）及び下方向き流路６１を、弁機構Ｖの弁座２０ａ及び弁体２５の円盤状本体２５ｂの上方側に配置するとともに、注出流路３１における弁機構Ｖの下流側の部位の上方側に配置する構成とし、下方向き流路６１の下流側端部に開口形成された蒸気導出口３２Ｃを、弁機構Ｖの弁体２５の円盤状本体２５ｂに対して上下方向で対向する状態で、注出流路３１における弁機構Ｖの下流側の部位に開口するように構成したが、このような構成に限らず、導出用水平向き流路６０Ｂの一部（水平向き分岐流路６０ｂ）、下方向き流路６１及び蒸気導出口３２Ｃのうちの少なくとも一つを弁機構Ｖの弁体２５の円盤状本体２５ｂに対して上下方向で重なる位置に配設するように構成し、その他を当該円盤状本体２５ｂの上方側に位置させず、注出流路３１における弁機構Ｖの下流側の部位の上方側に配置する構成としてもよい。また、これらの全てを、当該円盤状本体２５ｂに対して上下方向で重ならない位置に配置したり、注出流路３１における弁機構Ｖの下流側の部位の上方側に配置しない構成とすることもできる。
例えば、水平向き分岐流路６０ｂ、下方向き流路６１及び蒸気導出口３２Ｃを、円盤状本体２５ｂよりも径方向外方側に位置させて、注出流路３１における弁機構Ｖの下流側の部位の上方側に位置させるように構成することもできる。このように構成しても、蓋体６内における上下方向及び水平方向のコンパクト性を確保した上で、水平向き流路６０及び下方向き流路６１の流路長を長くすることができる。 (C) In the above-described embodiment, a part of the derivation horizontal flow path 60B (horizontal branch flow path 60b) and the downward flow path 61 are separated from the valve seat 20a of the valve mechanism V and the disc-shaped main body 25b of the valve body 25. And a steam outlet 32C formed at the downstream end of the downward-facing flow passage 61 so as to be disposed above the downstream portion of the valve mechanism V in the extraction flow passage 31. Is configured to open to a downstream portion of the valve mechanism V in the extraction flow path 31 in a state of facing the disc-shaped main body 25b of the valve body 25 of the valve mechanism V in the vertical direction. Not only the configuration but also at least one of the part of the derivation horizontal channel 60B (horizontal branch channel 60b), the downward channel 61 and the steam outlet 32C of the valve body 25 of the valve mechanism V. Arranged so as to overlap with the disc-shaped body 25b in the vertical direction. To configured to, others not positioned on the upper side of the disc-shaped body 25b, may be disposed on the upper side of the portion of the downstream side of the Note overhead stream passage 31 in the valve mechanism V. Moreover, all of these should be arranged at a position that does not overlap with the disk-shaped main body 25b in the vertical direction, or not arranged above the downstream portion of the valve mechanism V in the extraction flow path 31. You can also.
For example, the horizontal branch flow path 60b, the downward flow path 61, and the steam outlet 32C are positioned on the radially outer side of the disc-shaped main body 25b, and the downstream side of the valve mechanism V in the extraction flow path 31. It can also comprise so that it may be located above the site | part. Even if comprised in this way, the flow path length of the horizontal direction flow path 60 and the downward direction flow path 61 can be lengthened, ensuring the compactness of the up-down direction and horizontal direction in the cover body 6. FIG.

（Ｄ）上記実施形態では、蒸気路形成部材４０は、上部材４１、下部材４２、温度検知具４３及びパッキン部材４４を組み付けることで構成したが、内部に蒸気流路３２の一部を形成できる構成であれば、蒸気路形成部材４０の構成を変更することができ、例えば、上部材４１と下部材４２とを一体物として構成したり、上部材４１や下部材４２の構成を更に分割した構成とすることができる。 (D) In the above embodiment, the steam path forming member 40 is configured by assembling the upper member 41, the lower member 42, the temperature detector 43 and the packing member 44, but forms a part of the steam channel 32 therein. If possible, the configuration of the steam path forming member 40 can be changed. For example, the upper member 41 and the lower member 42 can be configured as a single body, or the configurations of the upper member 41 and the lower member 42 can be further divided. Can be configured.

（Ｅ）上記実施形態では、水平向き流路６０を、電気ケトルの前後方向において接続部６２を介して略１８０度屈曲するように構成したが、接続部６２により適宜角度に屈曲させることができ、好ましくは９０度以上の角度、より好ましくは、１８０度程度に屈曲させることができる。また、水平向き流路６０の屈曲は、電気ケトルの左右方向に屈曲する構成とすることもできる。そして、これら屈曲は、一回屈曲するものに限らず、複数回ジグザグに屈曲するように構成することもでき、この場合、より一層蒸気の温度低下を促進して結露を促進することができる。 (E) In the above embodiment, the horizontal flow path 60 is configured to be bent approximately 180 degrees via the connection portion 62 in the front-rear direction of the electric kettle. However, the connection portion 62 can be bent at an appropriate angle. It can be bent at an angle of preferably 90 degrees or more, more preferably about 180 degrees. Further, the horizontal channel 60 can be bent in the left-right direction of the electric kettle. These bends are not limited to bend once but can be configured to be bent zigzag a plurality of times. In this case, condensation can be further promoted by further promoting the temperature drop of the steam.

A single-structure electric kettle that is not provided, that is, a configuration in which liquid is directly stored in the container body 4 (an example of a storage unit) may be used.

（Ｇ）上記実施形態では、湯沸し器の一例としての電気ケトルに本発明を適用したが、湯沸し器であれば、その他の機器であってもよく、例えば、電気ポットであってもよい。 (G) In the said embodiment, although this invention was applied to the electric kettle as an example of a water heater, if it is a water heater, another apparatus may be sufficient, for example, an electric kettle may be sufficient.
