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。   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.

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いる。
この蒸気流路は、貯留部の上部に当該貯留部と連通する共通蒸気室と、共通蒸気室と蒸気口とを連通する蒸気導出用流路と、共通蒸気室と蒸気の温度を検知する検知部とを連通する蒸気検知用流路とを備えている。蒸気検知用流路は、共通蒸気室の後側（把手側）に延出し、貯留部の後側から下方側に延出して、貯留部の下部に位置する検知部に到達するように構成されている。
これにより、貯留部内で発生した蒸気の一部が、蒸気導出用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、当該蒸気の他部が、蒸気検知用流路を通流して検知部に到達するように構成されている。 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. And a steam flow path for allowing the steam in the storage portion to flow to the outside through the steam port.
This steam flow path has a common steam chamber in communication with the storage section at the upper part of the storage section, a steam outlet flow path in communication with the common steam chamber and the steam port, and detection for detecting the temperature of the common steam chamber and steam. And a steam detection flow path communicating with the portion. The steam detection flow path is configured to extend to the rear side (the handle side) of the common steam chamber, extend from the rear side of the storage unit to the lower side, and reach the detection unit located below the storage unit. ing.
As a result, a part of the steam generated in the storage part flows through the steam outlet channel and is discharged to the outside from the steam port formed in the upper surface of the lid located above the storage part. The other part is configured to flow through the steam detection flow path and reach the detection part.

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導出用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 from the steam outlet through the steam outlet passage formed relatively short while maintaining the flow rate when rising from inside the reservoir. However, there is a concern that the humidity of the outside (indoors, etc.) will increase, and condensation and mold will occur.

そこで、特許文献２では、蒸気流路の蒸気導出用流路を、貯留部と注出流路とを連通するように設けることにより、貯留部内で発生した蒸気を蒸気導出用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構成の電気ケトルが開示されている。
また、特許文献３では、蒸気流路の蒸気導出用流路と蒸気検知用流路とを兼用して、蒸気流路の流路の一部に検知部を設けるとともに、当該蒸気流路における検知部の下流側を貯留部及び蓋体の外部に連通することにより、貯留部内で発生し蒸気流路を通流した蒸気を、貯留部に還流させたり、蓋体の外部に排出させる構成の電気ポットが開示されている。 Therefore, in Patent Document 2, by providing a steam outlet channel of the steam channel so that the storage unit and the extraction channel communicate with each other, the steam generated in the storage unit is removed from the steam outlet channel and the extraction channel. An electric kettle is disclosed that is configured to flow through a flow path and to be discharged to the outside through a spout.
Further, in Patent Document 3, a detection section is provided in a part of the flow path of the vapor flow path, and the detection in the vapor flow path is combined with the vapor flow path for the vapor flow path and the flow path for the vapor detection. By connecting the downstream side of the storage part to the outside of the storage part and the lid body, the steam generated in the storage part and flowing through the steam flow path is returned to the storage part or discharged to the outside of the lid body. A pot is disclosed.

これにより、特許文献２及び３に記載の電気ケトル等では、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ある程度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）の湿度の上昇を防止することができる。   Thereby, in the electric kettles and the like described in Patent Documents 2 and 3, steam is condensed when the steam flows through the steam channel and the extraction channel formed relatively long, and the steam is discharged from the spout. The amount can be reduced to some extent, and the possibility that a child or the like will come into contact with the steam discharged from the spout decreases, and an increase in the humidity outside the room (such as indoors) can be prevented.

特開２０１０−０８２３８３号公報JP 2010-082383 A 特開２００８−２１２３１５号公報JP 2008-212315 A 特開２０１２−２４５１３８号公報JP 2012-245138 A

ここで、特許文献２に記載の電気ケトルでは、特許文献１に記載の電気ケトルと同様に、蒸気検知用流路は共通蒸気室の後側（把手側）に延出し、貯留部の後側から下方側に延出して、貯留部の下部に位置する検知部に到達するように構成されている。そして、蒸気検知用流路の流路断面積は蒸気導出用流路の流路断面積よりも小さく構成されているため、共通蒸気室に導入された蒸気は主に蒸気導出用流路側に通流し、蒸気検知用流路側への蒸気の通流が比較的少なくなり、検知部での蒸気の温度の検知が遅れたり正確に検知できなかったりする虞があり、検知部での蒸気の温度検知の精度向上が望まれる。   Here, in the electric kettle described in Patent Document 2, like the electric kettle described in Patent Document 1, the steam detection flow path extends to the rear side (the handle side) of the common steam chamber, and the rear side of the storage unit. It is comprised so that it may extend to the downward side from and may reach the detection part located in the lower part of a storage part. Since the cross-sectional area of the steam detection channel is smaller than the cross-sectional area of the steam outlet channel, the steam introduced into the common steam chamber passes mainly to the steam outlet channel side. The temperature of the steam at the detector may be delayed or may not be detected accurately. Improvement of accuracy is desired.

また、特許文献３に記載の電気ポットでは、蒸気流路内の経路に設けられた検知部により、当該蒸気流路を通流する蒸気の温度をある程度検知できるものの、蒸気の通流状態（蒸気の通流量或いは流速の変動等）によっては、検知部での蒸気の温度の検知を正確に行うことができない虞がある。   In addition, in the electric pot described in Patent Document 3, the temperature of the steam flowing through the steam channel can be detected to some extent by the detection unit provided in the path in the steam channel. Depending on the flow rate or the flow rate fluctuation, the temperature of the steam may not be accurately detected by the detection unit.

一方で、特許文献１に記載の電気ケトルでは、蒸気導出用流路の入り口或いは蒸気導出用流路内の経路に、蒸気導出用流路から外部に排出される蒸気の量を制限する絞り部を設け、この絞り部により共通蒸気室から蒸気検知用流路に流れる蒸気の量を決定するように構成されている。これにより、検知部にて蒸気の温度が検知されるタイミングを調整して、沸騰時間の調整をすることができる。
この際、絞り部により、蒸気が検知部を備えた蒸気検知用流路にある程度滞留するが、貯留部にて発生する蒸気が蒸気検知用流路及び蒸気導出用流路に順次流入するため、当該蒸気が蒸気導出用流路を通流して蒸気口を介して外部（蓋体の上面）に排出されてしまう。
従って、検知部での蒸気の温度の検知をある程度精度よく検知できるものの、蓋体の上面に形成された蒸気口から蒸気が排出されてしまう。 On the other hand, in the electric kettle described in Patent Document 1, a throttle portion that limits the amount of steam discharged from the steam outlet channel to the entrance of the steam outlet channel or the path in the steam outlet channel. And the amount of steam flowing from the common steam chamber to the steam detection flow path is determined by the throttle portion. Accordingly, the boiling time can be adjusted by adjusting the timing at which the temperature of the steam is detected by the detection unit.
At this time, the steam is retained in the steam detection flow path provided with the detection part to some extent by the throttle part, but the steam generated in the storage part sequentially flows into the steam detection flow path and the steam discharge flow path, The steam flows through the steam outlet channel and is discharged to the outside (upper surface of the lid) through the steam port.
Therefore, although the detection of the temperature of the steam in the detection unit can be detected with a certain degree of accuracy, the steam is discharged from the steam port formed on the upper surface of the lid.

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、検知部での蒸気の温度検知を早めつつ精度を確実に向上させながら、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 its main problem is that the amount of steam discharged from the spout while improving the accuracy while accelerating the temperature detection of the steam at the detection unit. It is in the point which provides the water heater which can reduce reliably.

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、蒸気導入口を介して前記貯留部と連通し、前記蒸気導入口から導入された蒸気の温度を検知する検知部を備えた検知用蒸気流路と、当該検知用蒸気流路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、前記検知用蒸気流路からの蒸気を流路下流側に設けられた蒸気導出口を介して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導出用蒸気流路とを備え、
前記検知用蒸気流路と前記導出用蒸気流路との接続部及び当該接続部の下流側の一方又は両方に、前記検知用蒸気流路の流路断面積よりも小さな流路断面積の狭部を備える点にある。 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 flow path communicates with the storage section via a steam inlet, and includes a detection steam path provided with a detection section for detecting the temperature of the steam introduced from the steam inlet, and the detection steam flow A path and a downstream side of the valve mechanism in the extraction flow path, and the steam from the detection steam flow path passes through the steam outlet port provided on the downstream side of the flow path. A derivation steam flow path that flows to the downstream side of the valve mechanism,
One or both of the connection portion between the detection steam flow channel and the derivation steam flow channel and the downstream side of the connection portion have a narrow channel cross-sectional area smaller than the flow channel cross-sectional area of the detection steam flow channel. It is in the point with a part.

上記特徴構成によれば、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おり、また、蒸気流路が、蒸気導入口を介して貯留部と連通し、蒸気導入口から導入された蒸気の温度を検知する検知部を備えた検知用蒸気流路と、当該検知用蒸気流路と注出流路における弁機構の下流側とを連通し、検知用蒸気流路からの蒸気を流路下流側に設けら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通流させる導出用蒸気流路とを備えている。このため、注出流路を弁機構により閉鎖した状態において、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の全量（結露した蒸気以外）を、貯留部、蒸気流路（検知用蒸気流路、導出用蒸気流路）、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, the inside of the lid body is provided in the pouring channel and the pouring channel that communicates the reservoir and the outside, and allows the liquid in the reservoir to flow to the outside through the spout. , A valve mechanism that can open and close the discharge channel, and the reservoir and the downstream side of the valve mechanism in the discharge channel communicate with each other, and the steam generated from the liquid in the reservoir is downstream of the valve mechanism in the discharge channel And a steam flow path that communicates with the reservoir via the steam inlet and a detector that detects the temperature of the steam introduced from the steam inlet. The detection steam flow path is connected to the downstream side of the valve mechanism in the detection steam flow path and the extraction flow path, and the steam outlet port provided on the downstream side of the flow path for the steam from the detection steam flow path is provided. And a derivation steam channel for allowing flow to the downstream side of the valve mechanism in the extraction channel. For this reason, in the state which closed the extraction flow path by the valve mechanism, all the vapor | steam (except for the vapor | steam which condensed) by the heating of the liquid in the storage part by a heating mechanism is stored in a storage part, a steam flow path ( The detection steam flow path, the discharge steam flow path), the discharge flow path, and the spout are passed in this order to reduce the temperature in order, and condensation can occur in the steam flow path and the discharge flow path. The amount of steam discharged from the 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, 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、検知用蒸気流路と導出用蒸気流路との接続部及び当該接続部の下流側の一方又は両方に、検知用蒸気流路の流路断面積よりも小さな流路断面積の狭部を備えるので、接続部よりも上流側に位置する検知用蒸気流路、或いは、当該検知用蒸気流路及び導出用蒸気流路の一部に、蒸気導入口を介して導入された蒸気を積極的に滞留させ、この滞留する蒸気の温度を検知用蒸気流路内に設けられた検知部により早期且つ安定的に検知することができ、温度検知精度を確実に向上させることができる。
また、狭部を通過した後の導出用蒸気流路や注出流路においては、当該狭部よりも流路断面積が拡大することとなるため通流する蒸気の圧力が低下し、当該蒸気の結露をより促進することができる。 In particular, the steam flow path is smaller than the cross-sectional area of the detection steam flow path at one or both of the connection part of the detection steam flow path and the discharge steam flow path and the downstream side of the connection part. Since it has a narrow cross-sectional area, it is introduced via a steam inlet into a detection steam channel located upstream from the connection part, or a part of the detection steam channel and the outlet steam channel. The accumulated steam can be actively retained, and the temperature of the retained steam can be detected early and stably by the detection unit provided in the detection steam flow path, and the temperature detection accuracy can be reliably improved. Can do.
In addition, in the outlet steam channel and the extraction channel after passing through the narrow part, the flow passage cross-sectional area is larger than that of the narrow part, so the pressure of the flowing steam decreases, and the steam The dew condensation can be further promoted.

よって、検知部での蒸気の温度検知を早めつつ精度を確実に向上させながら、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 can be obtained, improving a precision reliably, speeding up the temperature detection of the vapor | steam in a detection part.

本発明に係る湯沸し器の更なる特徴構成は、前記接続部が、前記検知用蒸気流路の下流側端部を除く箇所と前記導出用蒸気流路とが接続される箇所に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 connecting portion is formed at a place where the downstream end of the detection steam channel is connected to the outlet steam channel. It is in.

上記特徴構成によれば、接続部が、検知用蒸気流路の下流側端部を除く箇所と導出用蒸気流路とが接続される箇所に形成されるので、少なくとも検知用蒸気流路の下流側端部よりも上流側の検知用蒸気流路内に蒸気を滞留させつつ、当該下流側端部よりも上流側における接続部を介して検知用蒸気流路内の蒸気を導出用蒸気流路に通流させることができる。
これにより、検知用蒸気流路の下流側端部に接続部を設ける構成と比較して、検知部の近傍に蒸気を滞留させ易くなって、検知部が蒸気の通流状態（蒸気の通流量や流速等）の変動による影響を受け難くなり、検知部における蒸気の温度検知を早めつつ精度をより向上させることができる。 According to the above characteristic configuration, the connecting portion is formed at a location where the portion excluding the downstream end of the detection steam channel and the outlet steam channel are connected, so at least downstream of the detection steam channel. Steam for deriving steam in the detection steam channel via a connection portion on the upstream side of the downstream end while retaining the steam in the detection steam channel on the upstream side of the side end Can be passed through.
This makes it easier for the steam to stay in the vicinity of the detection unit as compared with the configuration in which the connection portion is provided at the downstream end of the detection steam flow path, so that the detection unit has a steam flow state (steam flow rate). And it is difficult to be affected by fluctuations in the flow velocity, etc., and the accuracy of the detection can be further improved while speeding up the temperature detection of the steam in the detection unit.

本発明に係る湯沸し器の更なる特徴構成は、前記検知用蒸気流路において、前記蒸気導入口と前記検知部とが上流側から下流側に向かって記載順に配設され、
前記接続部が、前記検知用蒸気流路における前記蒸気導入口の下流側で且つ前記検知部の上流側の箇所と前記導出用蒸気流路とが接続される箇所に形成される点にある。 According to a further feature of the water heater according to the present invention, in the detection steam flow path, the steam inlet and the detection unit are arranged in the order described from the upstream side to the downstream side,
The connecting portion is formed at a location where the location on the downstream side of the steam inlet in the detection steam flow channel and the upstream side of the detection portion is connected to the derivation steam flow channel.

上記特徴構成によれば、接続部が、検知用蒸気流路における蒸気導入口の下流側で且つ検知部の上流側の箇所と導出用蒸気流路とが接続される箇所に形成されるので、少なくとも検知部よりも上流側の検知用蒸気流路内に蒸気を滞留させつつ、検知部の上流側における接続部を介して検知用蒸気流路内の蒸気を導出用蒸気流路に通流させることができる。
これにより、検知部の下流側に接続部を設ける構成と比較して、検知部の近傍に蒸気を滞留させ易くなって、検知部が蒸気の通流状態（蒸気の通流量や流速等）の変動による影響を受け難くなり、検知部における蒸気の温度検知を早めつつ精度をより向上させることができる。 According to the above characteristic configuration, the connecting portion is formed at a location downstream of the steam inlet in the detection steam passage and at a location where the upstream portion of the detection portion and the outlet steam passage are connected. The steam in the detection steam channel is caused to flow to the outlet steam channel through the connection portion on the upstream side of the detection unit while the steam is retained in at least the detection steam channel upstream of the detection unit. be able to.
This makes it easier for the steam to stay in the vicinity of the detection unit compared to the configuration in which the connection unit is provided on the downstream side of the detection unit. It becomes difficult to be influenced by fluctuations, and it is possible to improve the accuracy while speeding up the temperature detection of the steam in the detection unit.

本発明に係る湯沸し器の更なる特徴構成は、前記検知用蒸気流路が少なくとも直線状流路部を備え、
前記直線状流路部において、前記蒸気導入口と前記検知部とが上流側から下流側に向かって記載順に配設され、
前記接続部が、前記直線状流路部における前記蒸気導入口の下流側で且つ前記検知部の上流側の箇所と前記導出用蒸気流路とが接続される箇所に形成される点にある。 According to a further characteristic configuration of the water heater according to the present invention, the detection steam channel includes at least a linear channel part,
In the linear flow path portion, the steam inlet and the detection portion are arranged in the order of description from the upstream side toward the downstream side,
The connecting portion is formed at a location where the location on the downstream side of the steam inlet and the upstream side of the detection portion in the linear channel portion is connected to the outlet steam channel.

上記特徴構成によれば、接続部が、検知用蒸気流路の直線状流路部における蒸気導入口の下流側で且つ検知部の上流側の箇所と導出用蒸気流路とが接続される箇所に形成されるので、少なくとも検知部より上流側の検知用蒸気流路の直線状流路部内に蒸気を滞留させつつ、検知部の上流側における接続部を介して当該直線状流路部内の蒸気を導出用蒸気流路に通流させることができる。
これにより、検知部の下流側に接続部を設ける構成と比較して、検知部の近傍に蒸気を滞留させ易くなって、検知部が蒸気の通流状態（蒸気の通流量や流速等）の変動による影響を受け難くなり、検知部における蒸気の温度検知を早めつつ精度をより向上させることができる。
特に、検知用蒸気流路の直線状流路部において、蒸気導入口と検知部とが上流側から下流側に向かって記載順に配設されているので、蒸気導入口と検知部とは対向した位置に配置され、直線状流路部において蒸気導入口から導入された蒸気は検知部に向かって通流することとなる。このため、蒸気の通流状態が変動したとしても当該蒸気は確実に検知部に到達する。
よって、検知部が、蒸気の通流状態の変動による影響を受け難くなり、検知部における蒸気の温度検知をより一層早めつつ精度をより一層向上させることができる。 According to the above characteristic configuration, the connecting portion is located downstream of the steam inlet in the linear flow path portion of the detection steam flow path and where the upstream position of the detection section and the outlet steam flow path are connected. Therefore, the steam in the linear flow path part is connected via the connection part on the upstream side of the detection part while at least the steam stays in the straight flow path part of the detection steam flow path upstream of the detection part. Can be passed through the outlet steam flow path.
This makes it easier for the steam to stay in the vicinity of the detection unit compared to the configuration in which the connection unit is provided on the downstream side of the detection unit. It becomes difficult to be influenced by fluctuations, and it is possible to improve the accuracy while speeding up the temperature detection of the steam in the detection unit.
In particular, in the linear flow path portion of the detection steam flow path, since the steam introduction port and the detection portion are arranged in the order of description from the upstream side to the downstream side, the steam introduction port and the detection portion face each other. The steam disposed at the position and introduced from the steam inlet in the linear flow path portion flows toward the detection portion. For this reason, even if the flow state of the steam fluctuates, the steam surely reaches the detection unit.
Therefore, it becomes difficult for the detection unit to be affected by fluctuations in the flow state of the steam, and the accuracy of the detection can be further improved while further speeding up the temperature detection of the vapor in the detection unit.

本発明に係る湯沸し器の更なる特徴構成は、前記検知部が、前記検知用蒸気流路の下流側端部を閉塞するように設けられている点にある。   A further characteristic configuration of the water heater according to the present invention is that the detection unit is provided so as to close the downstream end of the detection steam flow path.

上記特徴構成によれば、検知部が検知用蒸気流路の下流側端部を閉塞するように設けられているので、蒸気導入口を介して検知用蒸気流路内に導入される蒸気を、少なくとも検知部による閉塞箇所よりも上流側及び狭部よりも上流側の空間で滞留させることができ、当該空間に配設される検知部による蒸気の温度検知をより一層早めつつ、検知精度をより一層確実に向上させることができる。特に、検知用蒸気流路が直線状流路部を備えている場合には、検知部が、当該直線状流路部の下流側端部を閉塞するように設けられるので、蒸気導入口から導入された蒸気が検知部に向かって確実に通流できるとともに、検知部近傍で確実に滞留することとなり、検知部における蒸気の温度検知を確実に早めつつ、検知精度を確実に向上させることができる。   According to the above characteristic configuration, since the detection unit is provided so as to close the downstream end of the detection steam flow path, the steam introduced into the detection steam flow path through the steam introduction port, It can be retained at least in the space upstream from the closed part by the detection part and upstream from the narrow part, and the detection temperature of the steam by the detection part arranged in the space is further accelerated, and the detection accuracy is further improved. It can improve more reliably. In particular, when the detection steam flow path has a straight flow path portion, the detection section is provided so as to close the downstream end of the straight flow path portion. The detected steam can surely flow toward the detection unit and can stay in the vicinity of the detection unit, so that the detection accuracy can be improved with certainty while quickly detecting the temperature of the vapor in the detection unit. .

本発明に係る湯沸し器の更なる特徴構成は、前記狭部が、前記接続部に設けられている点にある。   A further characteristic configuration of the water heater according to the present invention is that the narrow portion is provided in the connection portion.

上記特徴構成によれば、検知用蒸気流路の流路断面積よりも小さな流路断面積の狭部が接続部に設けられているので、狭部の上流側の空間をできるだけ少なく、即ち、当該空間を検知用蒸気流路のみとすることができ、検知用蒸気流路内に蒸気を滞留させ易くして、検知部における蒸気の温度検知をさらに早めつつ、検知精度をさらに向上させることができる。   According to the above characteristic configuration, since the narrow portion of the flow passage cross-sectional area smaller than the flow passage cross-sectional area of the detection steam flow passage is provided in the connection portion, the space on the upstream side of the narrow portion is minimized, that is, The space can be limited to the detection steam channel, and it is easy to retain the steam in the detection steam channel, thereby further improving the detection accuracy while further detecting the temperature of the steam in the detection unit. it can.

本発明に係る湯沸し器の更なる特徴構成は、前記検知用蒸気流路において、前記蒸気導入口と前記検知部とが上流側から下流側に向かって記載順に配設され、
前記接続部が、前記検知用蒸気流路における前記蒸気導入口側よりも前記検知部側に偏倚した箇所に接続されている点にある。 According to a further feature of the water heater according to the present invention, in the detection steam flow path, the steam inlet and the detection unit are arranged in the order described from the upstream side to the downstream side,
The connection portion is connected to a location that is biased toward the detection portion rather than the steam inlet side in the detection steam flow path.

上記特徴構成によれば、接続部が検知用蒸気流路における蒸気導入口側よりも下流側である検知部側に偏倚した箇所に接続されているので、蒸気導入口から検知用蒸気流路内に導入された蒸気は、検知部に比較的近い部位にまで通流して接続部に到達することとなるため、検知部近傍に蒸気を通流させ易くなり、当該蒸気の温度の早期検知及び検知精度の向上を期待することができる。   According to the above characteristic configuration, since the connecting portion is connected to a position biased to the detection portion side that is downstream of the steam introduction port side in the detection steam flow channel, the connection portion is connected to the detection steam flow channel from the steam introduction port. Since the steam introduced into the gas flows to a part relatively close to the detection part and reaches the connection part, it is easy to let the steam flow near the detection part, and early detection and detection of the temperature of the steam. An improvement in accuracy can be expected.

本発明に係る湯沸し器の更なる特徴構成は、前記検知用蒸気流路が、水平方向に延出し、前記蒸気導入口を介して前記貯留部に連通する検知用水平向き流路を備え、
前記導出用蒸気流路が、水平方向に延出し、前記接続部を介して前記検知用水平向き流路に連通する導出用水平向き流路と、当該導出用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前記蒸気導出口を介して前記注出流路における前記弁機構の下流側に連通する導出用下方向き流路とを備える点にある。 According to a further feature of the water heater according to the present invention, the detection steam channel includes a detection horizontal channel that extends in a horizontal direction and communicates with the storage unit via the steam inlet,
The derivation steam channel extends in the horizontal direction and communicates with the detection horizontal channel through the connection portion, and extends downward from the derivation horizontal channel. A derivation downward channel that communicates with the downstream side of the valve mechanism in the extraction channel via the steam outlet port formed at the downstream end.

上記特徴構成によれば、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検知用水平向き流路内を通流し、接続部を介して導出用水平向き流路内を通流する。この際、蒸気は、接続部及び接続部の下流側の一方又は両方に設けられた狭部よりも上流側の空間（検知用水平向き流路内、或いは、検知用水平向き流路及び導出用水平向き流路の一部）に滞留し、検知部における蒸気の温度の検知精度が向上する。
さらに、蒸気は、導出用水平向き流路を通流し、当該導出用水平向き流路から下方側に延出する導出用下方向き流路を通流して、当該導出用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に導出される。この際、蒸気は、狭部を通過して当該狭部よりも流路断面積が拡大した導出用水平向き流路、導出用下方向き流路、注出流路等を通流する際に圧力が低下し、結露が促進される。また、導出用水平向き流路内を通流する蒸気は、導出用下方向き流路に導入される際に当該導出用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、当該蒸気は導出用下方向き流路の入り口付近で滞留することとなる。即ち、蒸気が導出用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低下することができるのである。
これにより、導出用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、蒸気が検知用水平向き流路及び導出用水平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して、蒸気の量を低減することができる。このように蒸気の量を低減させた状態で、更に、当該蒸気を導出用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おける弁機構の下流側に導出し、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一層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）の温度の上昇も確実に防止することができる。 According to the above characteristic configuration, the steam generated in the storage part rises, and first flows through the detection horizontal channel through the steam inlet, and then flows through the connection horizontal channel through the connection unit. Circulate. At this time, the vapor is upstream of the narrow portion provided on one or both of the connection portion and the connection portion (in the detection horizontal flow path or in the detection horizontal flow path and for the discharge). It stays in a part of the horizontal flow path), and the detection accuracy of the temperature of the steam in the detection unit is improved.
Further, the steam flows through the derivation horizontal channel, passes through the derivation downward channel extending downward from the derivation horizontal channel, and is downstream of the derivation downward channel. It is led out to the extraction channel through a steam outlet formed at the end. At this time, the vapor passes through the narrow portion and is pressurized when flowing through the derivation horizontal channel, the derivation downward channel, the extraction channel, etc. whose channel cross-sectional area is larger than that of the narrow portion. Decreases and condensation is promoted. Further, when the steam flowing through the derivation horizontal channel is introduced into the derivation downward channel, the steam is forced to flow along the downward direction in the derivation downward channel. Since the direction is changed, the steam stays in the vicinity of the entrance of the downward flow path for derivation. That is, when the steam is introduced into the downward flow path for lead-out, the direction of the relatively high-temperature steam is forced to be changed downward in the direction opposite to the direction in which the steam is going to rise (upward). The flow rate of the steam can be satisfactorily reduced.
As a result, the flow velocity of the steam flowing through the outlet downward flow path is relatively lowered, and the flow velocity of the vapor flowing through the detection horizontal flow path and the discharge horizontal flow path is reduced. It is possible to reduce the amount of steam by promoting the temperature drop of the steam and promoting condensation. In a state where the amount of steam is reduced in this way, further, the downstream side of the valve mechanism in the discharge channel through the steam outlet port formed at the downstream end of the downward channel for discharging the steam. Therefore, the steam discharged from the spout can be further reduced.
Therefore, it is possible to reduce the possibility that a child or the like will come into contact with the steam, and to reliably prevent an increase in the outside (indoor) temperature.

本発明に係る湯沸し器の更なる特徴構成は、前記検知用水平向き流路と前記導出用水平向き流路とが、前記接続部により相互に９０度以上屈曲した状態で接続される点にある。   A further characteristic configuration of the water heater according to the present invention lies in that the detection horizontal flow path and the derivation horizontal flow path are connected to each other in a state of being bent at 90 degrees or more by the connection portion. .

上記特徴構成によれば、検知用水平向き流路と導出用水平向き流路とが接続部により相互に９０度以上屈曲した状態で接続されるので、蒸気導入口から導入された蒸気が、検知用水平向き流路内を通流した後、接続部を介して導出用水平向き流路内を通流するためには、接続部にて９０度以上方向変換する必要が生じ、導出用水平向き流路内への導入が阻害され流速が低下し、当該蒸気の検知用水平向き流路内における滞留を促進することができ、検知部での蒸気の温度の検知を早めつつ検知精度を向上させることができる。
また、検知用水平向き流路を通流する蒸気が接続部にて９０度以上屈曲する際における流速の低下により、当該蒸気の温度の低下を促進することができ結露を促進することができる。 According to the above characteristic configuration, the detection horizontal direction flow path and the derivation horizontal direction flow path are connected to each other in a state of being bent at 90 degrees or more by the connection portion, so that the steam introduced from the steam introduction port is detected. After flowing through the horizontal flow channel for use, in order to flow through the horizontal flow channel for derivation through the connecting portion, it is necessary to change the direction by 90 degrees or more at the connecting portion. Introducing into the flow path is hindered and the flow velocity is reduced, so that the steam can stay in the horizontal flow path for detection, and the detection accuracy is improved while the detection of the temperature of the steam at the detection unit is accelerated. be able to.
Moreover, the fall of the flow velocity when the vapor | steam which flows through the horizontal direction flow path for a detection bends 90 degree | times or more in a connection part can accelerate | stimulate the fall of the temperature of the said vapor | steam, and can promote dew condensation.

本発明に係る湯沸し器の更なる特徴構成は、前記導出用水平向き流路の一部及び前記導出用下方向き流路が、前記弁機構の一部の上方側に位置し、
前記導出用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対向する状態で、前記注出流路における前記弁機構の下流側の部位に開口する点にある。 A further characteristic configuration of the water heater according to the present invention is such that a part of the horizontal channel for derivation and a downward channel for derivation are located above a part of the valve mechanism,
In the state where the steam outlet opening formed at the downstream end of the outlet downward channel is opposed to a part of the valve mechanism in the vertical direction, the valve mechanism in the outlet channel It is in the point which opens to the site | part of the downstream.

上記特徴構成によれば、導出用水平向き流路の一部及び導出用下方向き流路が、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導出用水平向き流路の一部及び導出用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、導出用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下することとなる。
これにより、蒸気が注出流路内を通流する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, since the part of the derivation horizontal channel and the part of the derivation downward channel are located above the part of the valve mechanism that can open and close the extraction channel, the valve mechanism can be opened and closed. Can control the flow of the liquid in the reservoir through the spout well, while moving a part of the valve mechanism and a part of the horizontal channel for derivation of the steam channel and a downward channel for derivation in the vertical direction. It can arrange | position in piles and can attain downsizing in the up-down direction.
Also, the steam outlet opening formed at the downstream end of the outlet downward flow path faces the part of the valve mechanism in the vertical direction, and the downstream side of the valve mechanism in the outlet flow path Since the steam opens to the part, the steam led out from the steam outlet to the part downstream of the valve mechanism in the discharge flow path collides with a part of the upper part of the valve mechanism, and the steam flow velocity decreases. Become.
As a result, the flow velocity at which the steam flows through the discharge channel can be further reduced, and the temperature decrease of the steam is further promoted to promote condensation and further reduce the amount of steam. be able to.

本発明に係る湯沸し器の更なる特徴構成は、前記蒸気導入口が、前記検知用蒸気流路の底壁部に前記貯留部と連通するように上下方向に貫通形成され、
前記検知用蒸気流路の天井壁部において前記蒸気導入口と対向する箇所に、前記検知用蒸気流路の上流側から下流側に向かって流路断面積が大きくなるテーパー傾斜面が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 such that the steam inlet is vertically formed so as to communicate with the storage portion at the bottom wall portion of the detection steam flow path,
A tapered inclined surface having a channel cross-sectional area that increases from the upstream side to the downstream side of the detection steam channel is formed at a position facing the steam inlet in the ceiling wall portion of the detection steam channel. There is in point.

上記特徴構成によれば、貯留部内で発生した蒸気が上昇し、検知用蒸気流路の底壁部において上下方向に貫通形成された蒸気導入口を介して、当該検知用蒸気流路内の天井壁部に向かって流入する。そして、当該蒸気は、検知用蒸気流路の天井壁部において蒸気導入口と対向する箇所に形成され且つ検知用蒸気流路の上流側から下流側に向かって流路断面積が大きくなるテーパー傾斜面に沿って案内され、検知用蒸気流路の下流側に向かって通流することとなる。
これにより、蒸気導入口から導入された蒸気を検知用蒸気流路の下流側に向かって適切に案内した状態で確実に通流させることができ、当該蒸気を検知用蒸気流路に設けられた検知部へ確実に通流させることができ、検知部における蒸気の温度の検知を早めつつ検知精度を向上させることができる。 According to the above characteristic configuration, the steam generated in the storage part rises, and the ceiling in the detection steam channel passes through the steam inlet formed in the bottom wall part of the detection steam channel in the vertical direction. It flows into the wall. Then, the steam is formed at a location facing the steam inlet in the ceiling wall portion of the detection steam flow path, and the taper slope in which the flow path cross-sectional area increases from the upstream side to the downstream side of the detection steam flow path. It is guided along the surface and flows toward the downstream side of the detection steam flow path.
Thereby, the steam introduced from the steam inlet can be surely flowed in a state of being properly guided toward the downstream side of the detection steam channel, and the steam is provided in the detection steam channel. The detection part can be surely passed, and the detection accuracy can be improved while the detection of the temperature of the steam in the detection part is accelerated.

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). ).

弁機構Ｖは、蓋本体部材２０に設けられる弁座２０ａと、当該弁座２０ａに当接した状態で湯水の流出を阻止する弁体２５と、この弁体２５を内蓋板２２の上面との間で閉状態側（上側）に付勢するスプリング２７とを備えて構成され、弁機構Ｖの弁体２５が上下方向に移動して、当該弁体２５と弁座２０ａとが当接又は離間することにより、注出流路３１を開閉自在に構成されている。具体的には、弁体２５は、上下方向に延出する弁軸２５ａと、当該弁軸２５ａの下方側部位において径方向外方に向けて概略円盤状に延出する円盤状本体２５ｂと、円盤状本体２５ｂの下面から円筒状に延出するスプリング取付部２５ｃとを備えている。そして、スプリング取付部２５ｃと内蓋板２２の上面との間にスプリング２７を取付け、弁軸２５ａを上下方向に移動させることで、円盤状本体２５ｂの上面と弁座２０ａとが当接又は離間し、注出流路３１を開閉自在に構成されている。
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.

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。

この蒸気流路３２のうち、蒸気導入口３２Ａ、３２Ｂと、水平方向に延出し、蒸気導入口３２Ａ、３２Ｂを介して連通空間３０に連通する水平向き流路６０と、当該水平向き流路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に連通する下方向き流路６１の一部とが、蒸気流路形成部材４０により形成される。 Next, based on FIGS. 2-9, the steam flow path 32 which is the characteristic structure of this application is demonstrated.
As described above, the steam flow path 32 communicates the communication space 30 facing the inner container 3 and the downstream side of the valve mechanism V in the discharge flow path 31 to pour out steam generated from the hot water in the inner container 3. The flow path 31 is configured to flow downstream of the valve mechanism V. Specifically, as shown in FIGS. 2, 4, and 6 to 9, the steam flow path 32 includes, from the upstream side, a steam flow hole, a communication space 30, an overturn stop valve Q, a steam inlet 32 </ b> A, 32B, a horizontal channel 60, a downward channel 61, and a steam outlet 32C.

The protruding outer wall 42a and the protruding inner wall 42c of the lower member 42 can be fitted with fitting protrusions (not shown) of the protruding outer wall 41a and protruding inner wall 41c of the upper member 41, which will be described later, at the center in the thickness direction. A groove (not shown) is formed.

また、下部材４２の下面には、蓋本体部材２０の上部に装着された状態で、転倒止水弁Ｑにおける弁収容部の外周縁部に形成された位置決め用リブ２０ｂを嵌合可能な環状溝４２ｆが窪み形成されており、下部材４２を蓋部材２０の上部に装着する際に、環状溝４２ｆを位置決め用リブ２０ｅに嵌合させることで容易に位置決めできるように構成されている。なお、位置決め用リブ２０ｅの外周側には環状シール材（図示せず）が設けられており、転倒止水弁Ｑの外周縁部と下部材４２の下面との間は密封される。   In addition, a positioning rib 20b formed on the outer peripheral edge portion of the valve housing portion of the overturn stop valve Q in a state where the lower member 42 is mounted on the upper portion of the lid main body member 20 can be fitted. The groove 42f is formed as a depression, and when the lower member 42 is mounted on the upper part of the lid member 20, the annular groove 42f is fitted to the positioning rib 20e so that the positioning can be easily performed. An annular seal material (not shown) is provided on the outer peripheral side of the positioning rib 20e, and the space between the outer peripheral edge of the overturn stop valve Q and the lower surface of the lower member 42 is sealed.

A projecting outer wall 41a projecting downward from the lower surface is formed, and an opening 41b that opens toward the handle 8 side, which is the rear side in the front-rear direction, is formed at a portion where the packing member 44 is mounted. Accordingly, a horizontal space in which the front side (spout 9 side), the left and right sides, and the upper side are surrounded by the plate-like member and the protruding outer wall 41a inside the protruding outer wall 41a and the rear side (the handle 8 side) is open. Is formed.

上部材４１の板状部材（天井壁部）における後側（把手８側）の開口部４１ｂを臨む部位において、上述の蒸気導入口３２Ａに対して上下方向で対向する箇所には、前後方向における前側（注ぎ口９側）から後側（把手８側）に向かって（蒸気流路３２の上流側から下流側に向かって）流路断面積が大きくなるテーパー傾斜面４１ｅが形成されている。そして、テーパー傾斜面４１ｅを、後側以外の３方向（前側、左右側）で囲繞するように、板状部材の下面から下方に突出する概略Ｕ字形状の突出内壁４１ｃが形成され、後側（把手８側）に向かって開口する開口部４１ｄが形成されている。即ち、突出内壁４１ｃの内側には、板状部材及び突出内壁４１ｃにより前側（注ぎ口９側）、左右側、上側の４方向が囲繞され、後側（把手８側）が開口する水平向き空間が形成される。突出内壁４１ｃにおける開口部４１ｄを形成する両端部のうち一方側（下面視で、前後方向に沿って後側から前側に向かって左側）の端部は、開口部４１ｂを形成する突出外壁４１ａにおける一方側（下面視で、前後方向に沿って後側から前側に向かって左側）の壁部に一体的に接続され、また、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）の端部は、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。なお、前後方向において開口部４１ｄに対向する位置に、パッキン部材４４の貫通孔４４ｂが開口するように構成されている。
上部材４１の突出外壁４１ａ及び突出内壁４１ｃには、厚み方向の中央部に、下部材４２の突出外壁４２ａ及び突出内壁４２ｃの嵌合溝（図示せず）に嵌合できる嵌合凸部（図示せず）が形成されている。 In the portion facing the opening 41b on the rear side (the handle 8 side) in the plate-like member (ceiling wall portion) of the upper member 41, the portion facing the above-described steam inlet 32A in the vertical direction is in the front-rear direction. A tapered inclined surface 41e is formed so that the channel cross-sectional area increases from the front side (pour spout 9 side) to the rear side (grip 8 side) (from the upstream side to the downstream side of the steam channel 32). A substantially U-shaped projecting inner wall 41c projecting downward from the lower surface of the plate-like member is formed so as to surround the tapered inclined surface 41e in three directions other than the rear side (front side, left and right side). An opening 41d that opens toward (the handle 8 side) is formed. That is, a horizontal space inside the protruding inner wall 41c is surrounded by the plate-like member and the protruding inner wall 41c in the four directions of the front side (the pouring spout 9 side), the left and right sides, and the upper side, and the rear side (the handle 8 side) is open. Is formed. One end (on the bottom view, the left side from the rear side to the front side in the front-rear direction) of both end portions forming the opening 41d in the projecting inner wall 41c is an end of the projecting outer wall 41a that forms the opening 41b. The other end side of the end portion forming the opening 41d in the projecting inner wall 41c is integrally connected to the wall portion on one side (in the bottom view, the left side from the rear side to the front side in the front-rear direction). An end of the projecting outer wall 41a that extends toward the vicinity of the center portion in the left-right direction of the opening 41b and forms the opening 41b (in the bottom view, right side from the rear side to the front side in the front-rear direction) It is extended to the position which retreated to the spout 9 side rather than both ends (from the bottom view, it is a right side and a left side edge part from the rear side toward the front side along the front-back direction). In addition, it is comprised so that the through-hole 44b of the packing member 44 may open in the position facing the opening part 41d in the front-back direction.
On the projecting outer wall 41a and the projecting inner wall 41c of the upper member 41, fitting protrusions (not shown) that can be fitted in fitting grooves (not shown) of the projecting outer wall 42a and the projecting inner wall 42c of the lower member 42 are provided at the center in the thickness direction. (Not shown) is formed.

従って、上部材４１の突出外壁４１ａ及び突出内壁４１ｃの嵌合凸部が下部材４２の突出外壁４２ａ及び突出内壁４２ｃの嵌合溝に嵌合する状態で組み付けられると、当該嵌合された箇所においては、上部材４１と下部材４２とが密封された状態となっている。また、上部材４１及び下部材４２の開口部形成筒部４０Ａには、上部材４１の開口部４１ｂ及び下部材４２の開口部４２ｂが合わさることで開口部６０ａが形成されている。開口部形成筒部４０Ａには、当該開口部６０ａを密封するようにパッキン部材４４が装着される。そして、このように組み付けられた蒸気流路形成部材４０を蓋体６の蓋本体部材２０の上面に装着し、当該蓋体６を容器本体４の上方開口部４Ａに取り付けると、蒸気流路形成部材４０の内部に、蒸気導入口３２Ａ、３２Ｂ及び開口部６１ａのみが開放された流路が形成される。   Therefore, when the fitting protrusions of the protruding outer wall 41a and the protruding inner wall 41c of the upper member 41 are fitted in the fitting grooves of the protruding outer wall 42a and the protruding inner wall 42c of the lower member 42, the fitted portions The upper member 41 and the lower member 42 are in a sealed state. In addition, the opening 60a of the upper member 41 and the lower member 42 is formed by combining the opening 41b of the upper member 41 and the opening 42b of the lower member 42 with each other. A packing member 44 is attached to the opening forming cylinder 40A so as to seal the opening 60a. When the steam flow path forming member 40 assembled in this way is attached to the upper surface of the lid main body member 20 of the lid body 6 and the lid body 6 is attached to the upper opening 4A of the container main body 4, the steam flow path formation is performed. 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が配置され、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、前後方向に沿う直線状流路部として形成され、当該直線状流路部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。即ち、当該キャップ４３ａが、検知用水平向き流路６０Ａの直線状流路部の下流側端部を閉塞するように構成されている。   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 is introduced through the steam inlets 32A and 32B. Thus, it functions as a horizontal flow channel 60A for detection communicating with the communication space 30. The detection-oriented horizontal channel 60A is formed as a linear channel along the front-rear direction. In the linear channel, the steam inlets 32B, 32A and the temperature detector 43 are connected from the upstream side to the downstream side (from the front side). (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. That is, the cap 43a is configured to close the downstream end portion of the linear flow path portion of the detection-oriented horizontal flow path 60A.

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 and the inner side of the protruding outer wall 41a and the plate-like member of the upper member 41, 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の直線状流路部における蒸気導入口３２Ａ、３２Ｂの下流側で且つ温度検知具４３の上流側の箇所において、当該蒸気導入口３２Ａ、３２Ｂよりも下流側である当該温度検知具４３側に偏倚した位置と、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。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。この接続部６２の流路断面積Ｂは、後述するように、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となるように形成される。即ち、接続部６２に、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Ｂの狭部７０が形成されている。   The detection horizontal flow path 60A and the derivation horizontal flow path 60B are connected via a connection part 62, and the connection part 62 is a steam inlet in the linear flow path part of the detection horizontal flow path 60A. A position that is biased toward the temperature detector 43 that is downstream of the steam inlets 32A and 32B at a location downstream of 32A and 32B and upstream of the temperature detector 43, and a derivation horizontal channel It is formed at a location where 60B is connected. 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 the connection portion 62, the opening 60a is closed in close contact with the fitting portion 44a or the like of the packing member 44, but a predetermined gap is provided between the bottom portion of the fitting portion 44a and both end portions 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). The channel cross-sectional area B of the connecting portion 62 is formed to have a channel cross-sectional area smaller than the channel cross-sectional area C of the detection-oriented horizontal channel 60A, as will be described later. That is, a narrow portion 70 having a channel cross-sectional area B smaller than the channel cross-sectional area C of the detection-oriented horizontal channel 60A is formed in the connecting portion 62.

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通流の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 velocity of the flow can be reduced, and the steam can stay in the closed space 60C to promote the temperature drop of the steam and promote condensation. Has been.

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は直線状流路部として形成され、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 linear flow path part, and thereafter, in the bifurcated branch part 40D, the derivation horizontal flow path 60B is 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 positioned 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.

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の上方側に位置し、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 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, and each lead-out downward flow path The opening 61a provided at the downstream end of 61A and the pair of through-holes 20c (steam outlet 32C) provided in the lid main body member 20 are the disc-like main body 25b of the valve body 25 of the valve mechanism V and the valve seat. It opens in the upstream (upper side) site | part of the valve mechanism V in the extraction flow path 31 in the state facing 20a at an up-down direction. 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 inclined (for example, about ± 10 degrees) with respect to the horizontal direction.

従って、検知用水平向き流路６０Ａが、蒸気導入口３２Ａ、３２Ｂを介して内容器３を臨む連通空間３０と連通し、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が配設された検知用蒸気流路として機能する。
また、導出用水平向き流路６０Ｂ及び導出用下方向き流路６１Ａが、検知用蒸気流路としての検知用水平向き流路６０Ａと注出流路３１における弁機構Ｖの下流側とを連通し、検知用水平向き流路６０Ａからの蒸気を蒸気導出口３２Ｃを介して注出流路３１における弁機構Ｖの下流側に通流させる導出用蒸気流路として機能する。 Accordingly, the temperature detection for detecting the temperature of the steam introduced from the steam inlets 32A and 32B, with the detection-oriented horizontal channel 60A communicating with the communication space 30 facing the inner container 3 via the steam inlets 32A and 32B. It functions as a detection steam flow path in which the tool 43 is disposed.
Further, the derivation horizontal flow path 60B and the derivation downward flow path 61A communicate the detection horizontal flow path 60A as the detection steam flow path with the downstream side of the valve mechanism V in the extraction flow path 31. It functions as a derivation steam channel for allowing the steam from the detection-oriented horizontal channel 60A to flow to the downstream side of the valve mechanism V in the extraction channel 31 via the steam outlet 32C.

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、導出用下方向き流路６１Ａ（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７０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Ｃ、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 channel 60 including the detection horizontal channel 60A and the derivation horizontal channel 60B configured as described above, and the derivation downward channel 61A (downward channel 61), A part of the steam channel 32 is formed by the connecting part 62 that connects the horizontal channel 60 and the downward channel 61. As shown in FIGS. The path cross-sectional area B is formed so as to function as a narrow portion 70 having a channel cross-sectional area smaller than the channel cross-sectional area C of the detection-oriented horizontal channel 60A. Further, the flow passage cross-sectional area A of the downward flow passage 61 is equal to the flow passage cross-sectional area of the steam flow passage 32 (the flow passage cross-sectional area C of the detection-use horizontal flow passage 60A, the flow passage cut-off of the derivation horizontal flow passage 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（導出用下方向き流路６１Ａ）、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 (downward flow path 61A for derivation), 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とを備えており、また、蒸気流路３２が、蒸気導入口３２Ａ、３２Ｂを介して内容器３と連通し、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が配設された検知用水平向き流路６０Ａ（検知用蒸気流路）と、当該検知用水平向き流路６０Ａと注出流路３１における弁機構Ｖの下流側とを連通し、検知用水平向き流路６０Ａからの蒸気を蒸気導出口３２Ｃを介して注出流路３１における弁機構Ｖの下流側に通流させる導出用水平向き流路６０Ｂ及び導出用下方向き流路６１Ａ（導出用蒸気流路）とを備えている。このため、注出流路３１を弁機構Ｖにより閉鎖した状態において、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の全量（結露した蒸気以外）を、内容器３、蒸気流路３２（検知用水平向き流路６０Ａ、導出用水平向き流路６０Ｂ及び導出用下方向き流路６１Ａ）、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. A steam flow path 32 that flows to the downstream side of the valve mechanism V in the extraction flow path 31, and the steam flow path 32 communicates with the inner container 3 via the steam inlets 32A and 32B. A horizontal flow channel for detection 60A (detection vapor flow channel) in which a temperature detector 43 for detecting the temperature of the steam introduced from the steam inlets 32A and 32B is disposed, and a horizontal flow channel for detection 60A. The outlet channel 31 communicates with the downstream side of the valve mechanism V, and the steam from the detection-oriented horizontal channel 60A is introduced into the steam channel. And a through mouth 32C Note overhead stream horizontally oriented stream for deriving to flow through the downstream side of the valve mechanism V in path 31 path 60B and derived for the downward-looking channel 61A (lead-steam flow path). For this reason, in a state where the pouring channel 31 is closed by the valve mechanism V, the total amount of steam generated in the inner container 3 by heating the hot water in the inner container 3 by the electric heater 5 (other than condensed steam) The inner container 3, the steam channel 32 (detection horizontal channel 60 </ b> A, lead-out horizontal channel 60 </ b> B and lead-out downward channel 61 </ b> A), the pouring channel 31, and the spout 9 are sequentially passed through the temperature sequentially. Can be dewed in the steam flow path 32 and the discharge flow path 31, 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.

説明を加えると、内容器３内で発生した蒸気は上昇して、まず、検知用水平向き流路６０Ａを形成する蒸気流路形成部材４０の下部材４２の板状部材（底壁部）において上下方向に貫通形成された蒸気導入口３２Ａ、３２Ｂを介して、検知用水平向き流路６０Ａを形成する蒸気流路形成部材４０の上部材４１の板状部材（天井壁部）に向かって当該検知用水平向き流路６０Ａ内に導入される。この際、当該蒸気は、検知用水平向き流路６０Ａの天井壁部において蒸気導入口３２Ａと対向する箇所に形成され且つ検知用水平向き流路６０Ａの上流側から下流側に向かって流路断面積が大きくなるテーパー傾斜面４１ｅに沿って案内され、検知用水平向き流路６０Ａの下流側に向かって通流することとなる。
これにより、蒸気導入口３２Ａ、３２Ｂから導入された蒸気を検知用水平向き流路６０Ａの下流側に向かって適切に案内した状態で確実に通流させることができ、当該蒸気を検知用水平向き流路６０Ａに設けられた温度検知具４３へ確実に通流させることができる。 When the explanation is added, the steam generated in the inner container 3 rises, and first, in the plate-like member (bottom wall part) of the lower member 42 of the steam flow path forming member 40 that forms the horizontal flow path 60A for detection. Through the steam inlets 32A, 32B penetrating in the vertical direction, toward the plate-like member (ceiling wall) of the upper member 41 of the steam flow path forming member 40 that forms the detection-oriented horizontal flow path 60A. It is introduced into the horizontal flow channel 60A for detection. At this time, the steam is formed at a position facing the steam inlet 32A in the ceiling wall portion of the detection-oriented horizontal flow path 60A, and the flow breaks from the upstream side to the downstream side of the detection-oriented horizontal flow path 60A. It is guided along the tapered inclined surface 41e having an increased area, and flows toward the downstream side of the horizontal flow channel 60A for detection.
Thereby, the steam introduced from the steam inlets 32A and 32B can be surely flowed in a state in which the steam is properly guided toward the downstream side of the horizontal flow path for detection 60A, and the steam is horizontally directed for detection. It is possible to reliably flow to the temperature detector 43 provided in the flow path 60A.

検知用水平向き流路６０Ａが直線状流路部を備え、当該直線状流路部において、蒸気導入口３２Ａ、３２Ｂと温度検知具４３とが上流側から下流側に向かって記載順に配設されているので、蒸気導入口３２Ａ、３２Ｂと温度検知具４３とは対向した位置に配置され、直線状流路部において蒸気導入口３２Ａ、３２Ｂから導入された蒸気は温度検知具４３に向かって通流することとなる。このため、蒸気の通流状態が変動したとしても当該蒸気は確実に温度検知具４３に到達する。特に、温度検知具４３のキャップ４３ａが、検知用水平向き流路６０Ａの直線状流路部の下流側端部を閉塞するように設けられるので、蒸気導入口３２Ａ、３２Ｂから導入された蒸気が温度検知具４３に向かって確実に通流できるとともに、温度検知具４３近傍で確実に滞留することとなり、温度検知具４３における蒸気の温度検知を確実に早めつつ、検知精度を確実に向上させることができる。   The detection-oriented horizontal flow path 60A includes a straight flow path portion, and in the straight flow path portion, the steam inlets 32A and 32B and the temperature detector 43 are arranged in the order of description from the upstream side to the downstream side. Therefore, the steam inlets 32A, 32B and the temperature detector 43 are arranged at positions facing each other, and the steam introduced from the steam inlets 32A, 32B in the linear flow path portion passes toward the temperature detector 43. It will flow. For this reason, even if the flow state of the steam fluctuates, the steam surely reaches the temperature detector 43. In particular, since the cap 43a of the temperature detector 43 is provided so as to close the downstream end of the linear flow path portion of the detection-oriented horizontal flow path 60A, the steam introduced from the steam inlets 32A and 32B. It is possible to reliably flow toward the temperature detection tool 43 and to stay in the vicinity of the temperature detection tool 43, and to reliably improve the detection accuracy while reliably accelerating the temperature detection of the steam in the temperature detection tool 43. Can do.

また、蒸気流路３２が、検知用水平向き流路６０Ａと導出用水平向き流路６０Ｂとの接続部６２に、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Ｂの狭部７０を備えるので、狭部７０の上流側の空間をできるだけ少なく、即ち、当該空間を検知用水平向き流路６０Ａのみとすることができ、接続部６２よりも上流側に位置する検知用水平向き流路６０Ａに、蒸気導入口３２Ａ、３２Ｂを介して導入された蒸気を積極的に滞留させ易くなり、この滞留する蒸気の温度を検知用水平向き流路６０Ａ内に設けられた温度検知具４３により早期且つ安定的に検知することができ、温度検知精度を確実に向上させることができる。   In addition, the steam flow path 32 is connected to the connecting portion 62 between the detection horizontal flow path 60A and the discharge horizontal flow path 60B, and has a flow path cross-sectional area smaller than the flow path cross-sectional area C of the detection horizontal flow path 60A. Since the narrow portion 70 of B is provided, the space on the upstream side of the narrow portion 70 is reduced as much as possible, that is, the space can be limited to only the horizontal flow channel 60A for detection, and is located upstream of the connecting portion 62. The steam introduced through the steam inlets 32A and 32B is easily retained in the detection horizontal channel 60A, and the temperature of the staying steam is provided in the detection horizontal channel 60A. The temperature detection tool 43 can detect it early and stably, and the temperature detection accuracy can be improved with certainty.

さらに、接続部６２が、検知用水平向き流路６０Ａの下流側端部を除く箇所と導出用水平向き流路６０Ｂとが接続される箇所、特に、検知用水平向き流路６０Ａの直線状流路部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るので、少なくとも温度検知具４３よりも上流側の検知用水平向き流路６０Ａの直線状流路部内に蒸気を滞留させつつ、温度検知具４３の上流側における接続部６２を介して当該直線状流路内の蒸気を導出用水平向き流路６０Ｂに通流させることができる。   Further, the connecting portion 62 is connected to a portion where the downstream end of the detection horizontal flow channel 60A is excluded and the derivation horizontal flow channel 60B, particularly the linear flow of the detection horizontal flow channel 60A. Since it is formed at a location downstream of the steam inlets 32 </ b> A and 32 </ b> B in the passage and upstream of the temperature detector 43 and a location where the outlet horizontal channel 60 </ b> B is connected, at least more than the temperature detector 43. While the steam stays in the straight flow path portion of the upstream detection horizontal flow path 60A, the steam in the straight flow path is led out through the connection portion 62 on the upstream side of the temperature detector 43. It can be made to flow through the flow path 60B.

検知用水平向き流路６０Ａにおける下流側端部が温度検知具４３により閉鎖されているので、蒸気導入口３２Ａ、３２Ｂを介して検知用水平向き流路６０Ａ内に導入される蒸気を、少なくとも温度検知具４３による閉塞箇所よりも上流側及び狭部７０よりも上流側の空間で滞留させることができ、当該空間に配設される温度検知具４３による蒸気の温度検知をより一層早めつつ、検知精度をより一層確実に向上させることができる。また、接続部６２が検知用水平向き流路６０Ａにおける温度検知具４３側に接続されているので、蒸気導入口３２Ａ、３２Ｂから検知用水平向き流路６０Ａ内に導入された蒸気は、温度検知具４３に比較的近い部位にまで通流して接続部６２に到達することとなるため、温度検知具４３近傍に蒸気を通流させ易くなり、当該蒸気の温度の早期検知及び検知精度の向上を期待することができる。   Since the downstream end of the detection horizontal flow path 60A is closed by the temperature detector 43, the steam introduced into the detection horizontal flow path 60A via the steam inlets 32A and 32B is at least the temperature. It can be retained in the space upstream from the closed position by the detector 43 and upstream from the narrow portion 70, and the detection of the vapor temperature by the temperature detector 43 disposed in the space is further accelerated. The accuracy can be improved more reliably. Further, since the connecting portion 62 is connected to the temperature detection tool 43 side in the detection horizontal flow path 60A, the steam introduced into the detection horizontal flow path 60A from the steam inlets 32A and 32B is detected by the temperature detection. Since it will flow to a part relatively close to the tool 43 and reach the connecting portion 62, it becomes easy to flow steam near the temperature detection tool 43, and early detection of the temperature of the steam and improvement of detection accuracy are facilitated. You can expect.

検知用水平向き流路６０Ａと導出用水平向き流路６０Ｂとが接続部６２により相互に略１８０度屈曲した状態で接続されるので、蒸気導入口３２Ａ、３２Ｂから導入された蒸気が、検知用水平向き流路６０Ａを通流した後、接続部６２を介して導出用水平向き流路６０Ｂ内を通流するためには、接続部６２にて略１８０度方向変換する必要が生じ、導出用水平向き流路６０Ｂ内への導入が阻害され流速が低下し、当該蒸気の検知用水平向き流路６０Ａ内における滞留を促進することができ、温度検知具４３での蒸気の温度の検知を早めつつ検知精度を向上させることができる。また、検知用水平向き流路６０Ａを通流する蒸気が接続部６２にて略１８０度屈曲する際における流速の低下により、当該蒸気の温度の低下を促進することができ結露を促進することができる。   Since the detection horizontal flow path 60A and the derivation horizontal flow path 60B are connected to each other in a state of being bent by about 180 degrees by the connecting portion 62, the steam introduced from the steam inlets 32A and 32B is detected. After flowing through the horizontal flow path 60A, in order to flow through the outlet horizontal flow path 60B via the connection portion 62, it is necessary to change the direction by approximately 180 degrees at the connection portion 62. The introduction into the horizontal channel 60B is hindered and the flow velocity is reduced, and the residence of the steam in the horizontal channel 60A for detection of vapor can be promoted, so that the temperature detection tool 43 can quickly detect the temperature of the steam. The detection accuracy can be improved. In addition, a decrease in the flow rate when the steam flowing through the detection horizontal flow path 60A bends approximately 180 degrees at the connection portion 62 can promote a decrease in the temperature of the steam and promote condensation. it can.

さらに、蒸気は、狭部７０を通過して当該狭部７０よりも流路断面積が拡大した導出用水平向き流路６０Ｂを通流することで圧力が低下し、結露が促進されつつ、当該導出用水平向き流路６０Ｂから下方側に延出する導出用下方向き流路６１Ａを通流して、当該導出用下方向き流路６１Ａ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に導出される。この際、導出用水平向き流路内６１Ａを通流する蒸気は、導出用下方向き流路６１Ａに導入される際に当該導出用下方向き流路６１Ａ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、当該蒸気は導出用下方向き流路６１Ａの入り口付近で滞留することとなる。即ち、蒸気が導出用下方向き流路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低下することができるのである。
これにより、導出用下方向き流路６１Ａ内を通流する蒸気の流速は比較的低下した状態となり、蒸気が検知用水平向き流路６０Ａ及び導出用水平向き流路６０Ｂ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して、蒸気の量を低減することができる。このように蒸気の量を低減させた状態で、更に、当該蒸気を導出用下方向き流路６１Ａ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一層低減することができる。 Further, the vapor passes through the narrow portion 70 and flows through the outlet horizontal flow channel 60B having a flow passage cross-sectional area larger than that of the narrow portion 70, thereby reducing the pressure and promoting the dew condensation. A derivation downward channel 61A extending downward from the derivation horizontal channel 60B is passed through the steam outlet 32C formed at the downstream end of the derivation downward channel 61A. It is led out to the extraction channel 31. At this time, the steam flowing through the derivation horizontal channel 61A flows along the downward direction in the derivation downward channel 61A when introduced into the derivation downward channel 61A. Therefore, the steam stays in the vicinity of the entrance of the outlet downward flow path 61A. That is, when the steam is introduced into the downward flow path 61 for discharge, the direction is forced to be changed downward in the direction opposite to the direction in which the relatively high temperature steam is going to rise (upward). The flow rate of the steam can be reduced satisfactorily.
As a result, the flow velocity of the steam flowing through the derivation downward flow passage 61A becomes relatively low, and the flow velocity of the vapor flowing through the detection horizontal flow passage 60A and the derivation horizontal flow passage 60B is reduced. The amount of steam can be reduced by promoting the temperature drop of the steam and promoting condensation. With the amount of steam reduced in this way, the steam is further led into the extraction channel 31 through the steam outlet 32C formed at the downstream end of the outlet downward channel 61A. Since it is discharged to the outside through the spout 9, the steam discharged from the spout 9 can be further reduced.

導出用水平向き流路６０Ｂの一部（水平向き分岐流路６０ｂ）及び導出用下方向き流路６１Ａが、注出流路３１を開閉自在な弁機構Ｖの一部（円盤状本体２５ｂ）の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の一部と蒸気流路３２の導出用水平向き流路６０Ｂの一部（水平向き分岐流路６０ｂ）及び導出用下方向き流路６１Ａ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、導出用下方向き流路６１Ａ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の一部（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ので、蒸気導出口３２Ｃから注出流路３１における弁機構Ｖの下流側の部位に導出された蒸気が、弁機構Ｖの一部（円盤状本体２５ｂ）の上部に衝突して、当該蒸気の流速が低下することとなる。
これにより、蒸気が注出流路３１内を通流する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。 A part of the valve mechanism V (disk-shaped main body 25b) in which the part of the outlet horizontal channel 60B (horizontal branch channel 60b) and the lower part of the outlet channel 61A can open and close the extraction channel 31 are provided. Since the valve mechanism V is located on the upper side, the flow of the hot water through the spout 9 in the inner container 3 can be controlled well by opening and closing the valve mechanism V. A part of the flow channel 60B (horizontal branch flow channel 60b) and the downward flow channel 61A for derivation can be arranged so as to overlap each other in the vertical direction, so that downsizing in the vertical direction can be achieved. In addition, the steam outlet 32C opened at the downstream end of the outlet downward flow passage 61A faces the part of the valve mechanism V (disk-shaped main body 25b) in the vertical direction, and is poured out. Since it opens to the downstream site | part of the valve mechanism V in the flow path 31, the vapor | steam derived | led-out from the steam outlet port 32C to the downstream site | part of the valve mechanism V in the extraction flow path 31 is a part of valve mechanism V ( Colliding with the upper part of the disc-shaped main body 25b), the flow velocity of the steam is lowered.
As a result, the flow velocity at which the steam flows through the extraction flow path 31 can be further reduced, and the temperature drop of the steam is further promoted and condensation is further promoted to further reduce the amount of steam. can do.

その後、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５への電力の供給を遮断する。   Thereafter, in the detection-oriented horizontal channel 60A, the temperature of the steam introduced from the steam inlets 32A and 32B and guided to the temperature detector 43 is detected, and when the temperature detector 43 detects a predetermined steam temperature, the contents Assuming that the hot water in the vessel 3 has reached a predetermined temperature, the control unit cuts off the supply of electric power to the electric heater 5.

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.

よって、温度検知具４３での蒸気の温度検知を早めつつ精度を確実に向上させながら、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 pouring spout 9 can be provided, improving a precision reliably, speeding up the temperature detection of the vapor | steam in the temperature detection tool 43.

（Ａ）上記実施形態では、図１０に模式的に示すように、検知用水平向き流路６０Ａを直線状流路部として形成し、直線状流路部の上流側に蒸気導入口３２Ａ、３２Ｂを設け下流側に温度検知具４３を設け、当該直線状流路部における蒸気導入口３２Ａ、３２Ｂの下流側で且つ温度検知具４３の上流側の箇所において、蒸気導入口３２Ａ、３２Ｂよりも当該温度検知具４３側に偏倚した位置と、導出用水平向き流路６０Ｂとが接続される箇所に、接続部６２を形成する構成とし、当該接続部６２に狭部７０を設ける構成とし、検知用水平向き流路６０Ａの直線状流路部と導出用水平向き流路６０Ｂとを接続部６２により略１８０度程度屈曲させて接続する構成としたが、例えば、（Ａ−１）〜（Ａ−９）に示すように、当該構成の全部または一部を適宜変更することができる。 [Another embodiment]
