本開示者らは、吐水装置のボディを、貯留室、絞り流路および吐出口の一部ずつの壁部を構成する第１の部材と、貯留室、絞り流路および吐出口の残りの壁部を構成する第２の部材と、に分割形成することを考えた。この場合、２部材のみで、貯留室、絞り流路および吐出口を効率的に形成できる。しかしながら、この場合、第１の部材に対する第２の部材の取り付け次第で、吐出口の寸法や形状が変わってしまい、意図した吐水状態を達成できないおそれがある点に、本開示者らは着目した。 The present disclosers have disclosed that the body of the water discharging device includes a first member that constitutes a wall portion of each of the storage chamber, the throttle channel, and the discharge port, and the remaining walls of the storage chamber, the throttle channel, and the discharge port. The idea was to form it separately into a second member constituting the section. In this case, the storage chamber, the throttle channel, and the discharge port can be efficiently formed using only two members. However, in this case, the present disclosure has focused on the fact that the dimensions and shape of the discharge port may change depending on the attachment of the second member to the first member, and there is a possibility that the intended water discharge state may not be achieved. .

本開示は、上記事情に鑑みてなされたものであり、意図した吐水状態を達成し易くすることを目的とする。 The present disclosure has been made in view of the above circumstances, and aims to make it easier to achieve the intended water discharging state.

以下、本発明の実施形態について、図面を参照しつつ説明する。ただし、本発明は、以下の実施形態に何ら限定されるものではなく、本発明の趣旨を逸脱ない範囲内で適宜変更して実施できる。 Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following embodiments, and can be implemented with appropriate modifications within the scope of the spirit of the present invention.

［第１実施形態］
図１に示すように、浴槽２００は、上側から見た平面視において、長方形状の形状をしている。吐水装置１Ａは、浴槽２００における短辺を構成する部分の上縁部２１０の上に取り付けられるボディ２８と、ボディ２８の内側に形成される流路９０とを有する。以下、流路９０における湯水Ｗの流れ方向に直交する水平方向を「横方向」といい、横方向に延在する形状を「横長」という。 [First embodiment]
As shown in FIG. 1, the bathtub 200 has a rectangular shape when viewed from above. The water discharging device 1A includes a body 28 attached to an upper edge 210 of a portion constituting a short side of the bathtub 200, and a flow path 90 formed inside the body 28. Hereinafter, the horizontal direction perpendicular to the flow direction of hot water W in the flow path 90 will be referred to as a "lateral direction", and the shape extending in the horizontal direction will be referred to as a "horizontally long".

吐水装置１Ａは、横長の扁平であり、流路９０の下流側の端部は、横長の吐出口９３を構成している。吐出口９３からは、浴槽２００に向けて、具体的には、入浴者の肩に向けて、湯水Ｗが横長の膜状に吐出される。 The water discharging device 1A is horizontally long and flat, and the downstream end of the flow path 90 constitutes a horizontally long discharge port 93. From the discharge port 93, hot water W is discharged in the form of a horizontally long film toward the bathtub 200, specifically toward the shoulders of the bather.

図２に示すように、浴槽２００と吐水装置１Ａとの間には、浴槽２００の湯水Ｗを吐水装置１Ａに供給するための給水系３００が設けられている。給水系３００は、上流側から順に、吸入口３０１と第１給水管３０２とポンプ３０３と第２給水管３０４とを有する。吸入口３０１は、浴槽２００の下部の内側面に設けられている。第１給水管３０２は、吸入口３０１とポンプ３０３とを接続している。第２給水管３０４は、ポンプ３０３と吐水装置１Ａとを接続している。ポンプ３０３は、浴槽２００の湯水Ｗを、第１給水管３０２を通して吸引して、第２給水管３０４を通して吐水装置１Ａに圧送する。 As shown in FIG. 2, a water supply system 300 for supplying hot water W from the bathtub 200 to the water spouting device 1A is provided between the bathtub 200 and the water spouting device 1A. The water supply system 300 includes, in order from the upstream side, an inlet 301, a first water supply pipe 302, a pump 303, and a second water supply pipe 304. The suction port 301 is provided on the inner surface of the lower part of the bathtub 200. The first water supply pipe 302 connects the suction port 301 and the pump 303. The second water supply pipe 304 connects the pump 303 and the water discharging device 1A. The pump 303 sucks hot water W from the bathtub 200 through the first water supply pipe 302 and pumps it through the second water supply pipe 304 to the water discharging device 1A.

図３に示すように、吐水装置１Ａのボディ２８は、横長の第１上流部材３０と、横長の第２上流部材４０と、横長の下流部材５０とに、分割形成されている。 As shown in FIG. 3, the body 28 of the water discharging device 1A is divided into a horizontally long first upstream member 30, a horizontally long second upstream member 40, and a horizontally long downstream member 50.

図４に示すように、第１上流部材３０は、下方に突出する筒状の導入部３１を有する。本実施形態では、導入部３１は２つであるが、１つであっても、３つ以上であってもよい。筒状の各導入部３１の内側は、導入孔９０ｈを構成している。第２給水管３０４の下流側部分は、２つに分岐しており、各下流側部分の端部は、円筒状の接続部材１０を介して導入部３１に接続される。これにより、各導入孔９０ｈに、給水系３００が接続される。 As shown in FIG. 4, the first upstream member 30 has a cylindrical introduction part 31 that projects downward. In this embodiment, there are two introduction parts 31, but there may be one, three or more introduction parts. The inside of each cylindrical introduction portion 31 constitutes an introduction hole 90h. The downstream portion of the second water supply pipe 304 is branched into two, and the end of each downstream portion is connected to the introduction portion 31 via the cylindrical connecting member 10. Thereby, the water supply system 300 is connected to each introduction hole 90h.

第２上流部材４０には、横長の照明装置６０と、横長の照明カバー７０と、が取り付けられる。第２上流部材４０は、上流部材３０に対して、上から組み合わされると共に、螺子等により結合される。 A horizontally long lighting device 60 and a horizontally long lighting cover 70 are attached to the second upstream member 40 . The second upstream member 40 is combined with the upstream member 30 from above and is coupled with a screw or the like.

第１上流部材３０と第２上流部材４０との間には、横長の貯留室９１と横長の絞り流路９２とが形成される。貯留室９１の底面には、導入孔９０ｈが連通している。第１上流部材３０には、前述の螺子を通すための支柱３４が、貯留室９１内を通過する形で突設されている。貯留室９１における浴槽２００側の側面には、絞り流路９２が連通している。絞り流路９２は、貯留室９１よりも流路断面積が小さい。 A horizontally long storage chamber 91 and a horizontally long throttle channel 92 are formed between the first upstream member 30 and the second upstream member 40 . An introduction hole 90h communicates with the bottom surface of the storage chamber 91. The first upstream member 30 is provided with a protruding support 34 for passing the above-mentioned screw through the storage chamber 91 . A throttle channel 92 communicates with the side surface of the storage chamber 91 on the bathtub 200 side. The throttle channel 92 has a smaller channel cross-sectional area than the storage chamber 91.

以下、第１上流部材３０および第２上流部材４０を、まとめて「上流部材３０，４０」という。下流部材５０は、上流部材３０，４０に対して、浴槽２００側から組み合わされると共に螺子等により結合される。下流部材５０には、絞り流路９２に連通する吐出口９３が、横長の貫通孔状に形成されている。 Hereinafter, the first upstream member 30 and the second upstream member 40 will be collectively referred to as "upstream members 30, 40." The downstream member 50 is combined with the upstream members 30 and 40 from the bathtub 200 side and is coupled with screws or the like. A discharge port 93 communicating with the throttle channel 92 is formed in the downstream member 50 in the shape of a horizontally long through hole.

本実施形態では、下流部材５０は、吐出口９３が一体形成された樹脂等の成型品であるが、それ以外であってもよい。具体的には、例えば、吐出口９３を有しない板状の部材に、吐出口９３を切削することにより、吐出口９３を有する下流部材５０が形成してもよい。また例えば、複数の分割体を溶着することにより、吐出口９３を有する下流部材５０を形成してもよい。また例えば、下流部材５０の材質は、金属等であってもよい。これらと同様に、第１上流部材３０および第２上流部材４０についても、樹脂等の成型品であってもよいし、それ以外であってもよい。 In the present embodiment, the downstream member 50 is a molded product made of resin or the like in which the discharge port 93 is integrally formed, but it may be made of other materials. Specifically, for example, the downstream member 50 having the discharge port 93 may be formed by cutting the discharge port 93 into a plate-shaped member that does not have the discharge port 93. Further, for example, the downstream member 50 having the discharge port 93 may be formed by welding a plurality of divided bodies. Further, for example, the material of the downstream member 50 may be metal or the like. Similarly to these, the first upstream member 30 and the second upstream member 40 may be molded products of resin or the like, or may be made of other materials.

図５に示すように、流路９０は、上流側から順に、導入孔９０ｈと貯留室９１と絞り流路９２と吐出口９３とを有する。以下、絞り流路９２および吐出口９３における流れ方向を「前」といい、前を向いた状態における左側、右側、後側を、それぞれ「左」「右」「後」という。 As shown in FIG. 5, the flow path 90 includes, in order from the upstream side, an introduction hole 90h, a storage chamber 91, a throttle flow path 92, and a discharge port 93. Hereinafter, the flow direction in the throttle channel 92 and the discharge port 93 will be referred to as "front", and the left side, right side, and rear side when facing forward will be referred to as "left," "right," and "rear," respectively.

本実施形態では、上流部材３０，４０が、導入孔９０ｈの全壁部と、貯留室９１の全壁部と、絞り流路９２の全壁部と、を構成している。 In this embodiment, the upstream members 30 and 40 constitute the entire wall of the introduction hole 90h, the entire wall of the storage chamber 91, and the entire wall of the throttle channel 92.

「導入孔９０ｈの全壁部」とは、導入孔９０ｈの流れ方向全区間における流れ方向回りの内周面全周である。つまり、導入孔９０ｈの流れ方向は、上方であるため、「導入孔９０ｈの全壁部」とは、導入孔９０ｈの上下方向全区間における上下方向回りの内周面全周である。 "The entire wall of the introduction hole 90h" refers to the entire circumference of the inner peripheral surface in the flow direction in the entire flow direction section of the introduction hole 90h. That is, since the flow direction of the introduction hole 90h is upward, the "entire wall portion of the introduction hole 90h" is the entire circumference of the inner peripheral surface in the vertical direction in the entire vertical section of the introduction hole 90h.

「貯留室９１の全壁部」とは、貯留室９１の底面、天井面、左内側面、右内側面、前側内側面、後側内側面の全てである。 "All walls of the storage chamber 91" refers to all of the bottom surface, ceiling surface, left inner surface, right inner surface, front inner surface, and rear inner surface of the storage chamber 91.

「絞り流路９２の全壁部」とは、絞り流路９２の流れ方向全区間における流れ方向回りの内周面全周である。つまり、絞り流路９２の流れ方向は、前方であるため、「絞り流路９２の全壁部」とは、絞り流路９２の底面、左内側面、天井面、右内側面の全てである。 “The entire wall portion of the throttle channel 92” refers to the entire circumference of the inner circumferential surface of the throttle channel 92 in the flow direction over the entire section in the flow direction. In other words, since the flow direction of the throttle channel 92 is forward, "the entire wall of the throttle channel 92" refers to all of the bottom surface, left inner surface, ceiling surface, and right inner surface of the throttle channel 92. .

上流部材３０，４０のうちの第１上流部材３０は、導入孔９０ｈの全壁部と、貯留室９１の下部の壁部と、絞り流路９２の下部の壁部と、を構成している。第２上流部材４０は、貯留室９１の上部の壁部と、絞り流路９２の上部の壁部と、を構成している。例えば、「貯留室９１の下部の壁部」は、貯留室９１の底面の全部と、貯留室９１の左内側面、右内側面、前側内側面、後側内側面のそれぞれの下部とからなる。 The first upstream member 30 of the upstream members 30 and 40 constitutes the entire wall of the introduction hole 90h, the lower wall of the storage chamber 91, and the lower wall of the throttle channel 92. . The second upstream member 40 constitutes an upper wall of the storage chamber 91 and an upper wall of the throttle channel 92. For example, "the lower wall of the storage chamber 91" includes the entire bottom surface of the storage chamber 91 and the lower portions of the left inner surface, right inner surface, front inner surface, and rear inner surface of the storage chamber 91. .

下流部材５０は、吐出口９３の全壁部を構成している。「吐出口９３の全壁部」とは、吐出口９３の流れ方向全区間における流れ方向回りの内周面全周である。つまり、吐出口９３の流れ方向は、前方であるため、「吐出口９３の全壁部」とは、吐出口９３の底面、左内側面、天井面、右内側面の全てである。なお、吐出口９３の流れ方向の大きさは、任意である。そのため、少なくとも流路９０の下流側の端の開口の全周を含んでいれば、「吐出口９３の全壁部」との条件を満たすことができる。 The downstream member 50 constitutes the entire wall of the discharge port 93. The "entire wall portion of the discharge port 93" refers to the entire circumference of the inner peripheral surface of the discharge port 93 in the flow direction over the entire section in the flow direction. That is, since the flow direction of the discharge port 93 is forward, "the entire wall of the discharge port 93" includes the bottom surface, the left inner surface, the ceiling surface, and the right inner surface of the discharge port 93. Note that the size of the discharge port 93 in the flow direction is arbitrary. Therefore, if at least the entire circumference of the opening at the downstream end of the flow path 90 is included, the condition of "the entire wall of the discharge port 93" can be satisfied.

給水系３００から導入孔９０ｈに湯水Ｗが供給されると、当該湯水Ｗは、導入孔９０ｈから横長の貯留室９１に流入して横方向に広がる。その後、当該湯水Ｗは、横長の絞り流路９２を通過して、横長の吐出口９３から横長の膜状に吐出される。 When hot water W is supplied from the water supply system 300 to the introduction hole 90h, the hot water W flows into the horizontally elongated storage chamber 91 from the introduction hole 90h and spreads laterally. Thereafter, the hot water W passes through the horizontally long throttle channel 92 and is discharged from the horizontally long discharge port 93 in the form of a horizontally long film.

図６に示すように、第１上流部材３０と第２上流部材４０との間には、止水用のパッキンＰが設けられている。これと同様に、上流部材３０，４０と下流部材５０との間にも、図示略の止水用のパッキンが設けられている。照明装置６０は、吐出口９３から吐出される湯水Ｗを照らす。 As shown in FIG. 6, a water-stop packing P is provided between the first upstream member 30 and the second upstream member 40. Similarly, a water-stop packing (not shown) is also provided between the upstream members 30, 40 and the downstream member 50. The lighting device 60 illuminates the hot water W discharged from the discharge port 93.

浴槽２００の上縁部には、上下方向に貫通する貫通孔２１１が設けられている。貫通孔２１１には、接続部材１０が挿入されている。接続部材１０の外周面には雄螺子１０ａが設けられており、雄螺子１０ａにナット１１が下から螺合することにより、浴槽２００の上縁部２１０に対して、吐水装置１Ａが取り付けられる。 A through hole 211 is provided at the upper edge of the bathtub 200, passing through the bathtub 200 in the vertical direction. The connecting member 10 is inserted into the through hole 211 . A male screw 10a is provided on the outer peripheral surface of the connecting member 10, and the water discharging device 1A is attached to the upper edge 210 of the bathtub 200 by screwing a nut 11 onto the male screw 10a from below.

以下に、本実施形態の構成および効果をまとめる。 The configuration and effects of this embodiment are summarized below.

ボディ２８が、上流部材３０，４０と下流部材５０とに分割形成されており、下流部材５０が、吐出口９３の全壁部を構成する。そのため、上流部材３０，４０から独立して、下流部材５０のみで吐出口９３の寸法を調整できる。そのため、吐出口９３の寸法を調整し易く、意図した吐水状態を達成し易い。 The body 28 is divided into upstream members 30 and 40 and a downstream member 50, and the downstream member 50 constitutes the entire wall portion of the discharge port 93. Therefore, the dimensions of the discharge port 93 can be adjusted by the downstream member 50 alone, independently from the upstream members 30 and 40. Therefore, it is easy to adjust the dimensions of the discharge port 93, and it is easy to achieve the intended water discharge state.

下流部材５０が１つであり、当該１の下流部材５０が、吐出口９３の全壁部を構成している。そのため、複数の下流部材５０が共働で、吐出口９３の全壁部を構成する場合と違い、１の下流部材に対する他の下流部材の取り付け次第で吐出口９３の寸法や形状が変わってしまう心配がない。そのため、当該１の下流部材５０の製造時に、吐出口９３の寸法を正しく調整しておけば、吐水装置１Ａの組み立て時や、浴槽２００に対する吐水装置１Ａの取り付け時等に、吐出口９３の寸法や形状がずれてしまう心配がない。 There is one downstream member 50, and the one downstream member 50 constitutes the entire wall portion of the discharge port 93. Therefore, unlike the case where a plurality of downstream members 50 work together to form the entire wall of the discharge port 93, the dimensions and shape of the discharge port 93 change depending on the attachment of other downstream members to one downstream member. No worries. Therefore, if the dimensions of the outlet 93 are adjusted correctly when manufacturing the first downstream member 50, the dimensions of the outlet 93 will be There is no need to worry about the shape changing.

上流部材３０，４０が複数あり、各上流部材３０，４０が、貯留室９１の一部ずつの壁部を構成している。そのため、１の上流部材が貯留室９１の全壁部を構成する場合に比べて、上流部材３０，４０を成形し易い。 There are a plurality of upstream members 30 and 40, and each upstream member 30 and 40 constitutes a wall portion of a portion of the storage chamber 91. Therefore, it is easier to mold the upstream members 30 and 40 than when one upstream member constitutes the entire wall of the storage chamber 91.

貯留室９１と絞り流路９２と吐出口９３とのそれぞれが、横方向に延在している。そのため、膜状の湯水Ｗを効率的に形成できる。 The storage chamber 91, the throttle channel 92, and the discharge port 93 each extend in the horizontal direction. Therefore, the film-like hot water W can be efficiently formed.

以下、他の実施形態について説明する。以下の実施形態については、指定する実施形態をベースにこれと異なる点を中心に説明し、当該指定の実施形態と同一又は類似の点については、適宜説明を省略する。 Other embodiments will be described below. The following embodiments will be described based on the specified embodiment, focusing on points different from the specified embodiment, and descriptions of points that are the same or similar to the specified embodiment will be omitted as appropriate.

［第２実施形態］
第２実施形態の吐水装置１Ｂについて、第１実施形態をベースに説明する。図７，図８に示すように、本実施形態では、絞り流路９２の壁部を構成する部分が、上流部材３０，４０ではなく、下流部材５０に属している。そのため、下流部材５０は、吐出口９３の全壁部に加えて、絞り流路９２の全壁部を構成している。 [Second embodiment]
A water discharging device 1B according to the second embodiment will be described based on the first embodiment. As shown in FIGS. 7 and 8, in this embodiment, the portion constituting the wall of the throttle channel 92 belongs to the downstream member 50 rather than the upstream members 30 and 40. Therefore, the downstream member 50 constitutes the entire wall of the throttle channel 92 in addition to the entire wall of the discharge port 93.

本実施形態は、例えば、上流部材３０，４０よりも下流部材５０の方が絞り流路９２を一体成形し易い場合や、上流部材３０，４０と下流部材５０との分割面を、貯留室９１と絞り流路９２との間に設定したい場合等に、好適に採用できる。 In this embodiment, for example, it may be easier to integrally mold the throttle channel 92 on the downstream member 50 than on the upstream members 30, 40, or the dividing surface between the upstream members 30, 40 and the downstream member 50 may be This can be suitably adopted when it is desired to set it between the flow path 92 and the throttle flow path 92.

［第３実施形態］
第３実施形態の吐水装置１Ｃについて、１つ前の第２実施形態をベースに説明する。図９，図１０に示すように、本実施形態では、第２実施形態でいう第１上流部材３０と第２上流部材４０とが、一の上流部材２９に統合されると共に、第２実施形態でいう第２上流部材４０の一部が、下流部材５０に属している。具体的には、貯留室９１の下流側部分の天井壁が、下流部材５０に属している。そのため、下流部材５０は、吐出口９３および絞り流路９２の全壁部に加えて、貯留室９１の一部の壁部を構成している。 [Third embodiment]
A water discharging device 1C according to the third embodiment will be described based on the previous second embodiment. As shown in FIGS. 9 and 10, in this embodiment, the first upstream member 30 and the second upstream member 40 in the second embodiment are integrated into one upstream member 29, and A part of the second upstream member 40 belongs to the downstream member 50. Specifically, the ceiling wall of the downstream portion of the storage chamber 91 belongs to the downstream member 50. Therefore, the downstream member 50 constitutes a part of the wall of the storage chamber 91 in addition to the entire wall of the discharge port 93 and the throttle channel 92.

以上のことから、本実施形態では、ボディ２８は、１の上流部材２９と１の下流部材５０との２部材に分割形成されており、当該２部材が、貯留室９１と絞り流路９２と吐出口９３との全壁部を構成している。 From the above, in this embodiment, the body 28 is divided into two members, one upstream member 29 and one downstream member 50, and these two members are connected to the storage chamber 91 and the throttle channel 92. It constitutes the entire wall portion with the discharge port 93.

本実施形態によれば、上流部材２９が１つであり、１の上流部材２９が、ボディ２８における下流部材５０以外の全部分を構成している。そのため、上流部材２９が２つである場合に比べて、吐水装置１Ｃの部品点数を削減できると共に、第１上流部材３０と第２上流部材４０とを螺子等で結合する必要性をなくして、図４に示す支柱３４を省略できる。そのため、上流部材２９の構成をシンプルにできる。 According to this embodiment, there is one upstream member 29, and one upstream member 29 constitutes all parts of the body 28 other than the downstream member 50. Therefore, compared to the case where there are two upstream members 29, the number of parts of the water discharging device 1C can be reduced, and there is no need to connect the first upstream member 30 and the second upstream member 40 with screws etc. The support column 34 shown in FIG. 4 can be omitted. Therefore, the configuration of the upstream member 29 can be simplified.

このように上流部材２９が１つであっても、下流部材５０が貯留室９１の一部の壁部を構成するため、上流部材２９の成形が極端に困難になることはない。 Even if there is only one upstream member 29 in this manner, since the downstream member 50 constitutes a part of the wall portion of the storage chamber 91, molding of the upstream member 29 does not become extremely difficult.

ボディ２８が、１の上流部材２９と１の下流部材５０との２部材に分割形成されているため、３部材以上に分割形成されている場合に比べて、吐水装置１Ｃの部品点数を削減することができる。 Since the body 28 is divided into two members, one upstream member 29 and one downstream member 50, the number of parts of the water discharging device 1C is reduced compared to a case where the body 28 is divided into three or more members. be able to.
