Description

本発明の実施形態は、洗濯機の注水ケース、及び洗濯機に関する。 Embodiments of the present invention relate to a water injection case for a washing machine and a washing machine.

一般に洗濯機は、注水装置を備えている。注水装置は、洗剤や柔軟剤が収納される注水ケースと、水道の蛇口等の外部の水源に接続された給水弁と、を有して構成されている。注水装置は、給水弁を開くことで外部の水源からの水を注水ケース内に供給し、注水ケース内を通過する水に洗剤や柔軟剤を溶解させて、その水を洗濯槽内に注水する。 A washing machine is generally equipped with a water injection device. The water injection device includes a water injection case in which detergent and softener are stored, and a water supply valve connected to an external water source such as a water faucet. The water injection device supplies water from an external water source into the water injection case by opening the water supply valve, dissolves detergent and softener in the water passing through the water injection case, and injects the water into the washing tub. .

注水ケースの構成として、例えば内部に曲がりくねった水路を設けたものがある。これによれば、給水弁から注水ケース内に供給された水の勢いを低減することができるため、注水ケースから勢い良く水が溢れ出てしまうことを防止することができる。この場合、注水ケースは、内部に曲がりくねった水路を有していることから、その構造が複雑になり易い。その結果、樹脂成形によって注水ケースを製造しようとすると、注水ケースを製造するための金型が複雑となり、注水ケースの製造コストが増大してしまう。 As a configuration of the water injection case, for example, there is a case in which a meandering water channel is provided inside. According to this, it is possible to reduce the momentum of the water supplied into the water injection case from the water supply valve, so it is possible to prevent the water from overflowing from the water injection case. In this case, the water injection case has a meandering water channel inside, so the structure tends to be complicated. As a result, when attempting to manufacture the water injection case by resin molding, the mold for manufacturing the water injection case becomes complicated, and the manufacturing cost of the water injection case increases.

そこで、例えば注水ケースを上下方向に二分割した構成がある。この構成によれば、各部品を製造するための金型を比較的単純な構造にすることができるため、注水ケースの製造コストの増大を抑制することができる。 Therefore, for example, there is a configuration in which the water injection case is vertically divided into two. According to this configuration, the metal mold for manufacturing each part can have a relatively simple structure, so an increase in the manufacturing cost of the water injection case can be suppressed.

一方、この場合、注水ケースの内部には、水道等の外部の水源からの高い水圧が加わるため、注水ケースを構成する各部品の接続部分を水密構造にする必要がある。各部品の水密性が不十分だと、部品間の隙間から水が漏れだし、更には水圧によってその隙間が拡大するおそれがある。そのため、従来構成では、例えば各部品の接続部分にシール部材等を設けて水密性を向上させるとともに、ネジ等の締結部材によって強固に接続する必要があった。 On the other hand, in this case, since a high water pressure from an external water source such as a tap is applied to the inside of the water injection case, it is necessary to make the connecting portions of the parts constituting the water injection case watertight. If the watertightness of each part is insufficient, water may leak from the gaps between the parts, and the gaps may expand due to water pressure. Therefore, in the conventional configuration, for example, it is necessary to improve the watertightness by providing a seal member or the like at the connection portion of each component, and to firmly connect the components with a fastening member such as a screw.

しかしながら、各部品を接続する際に、部品間にシール部材を配置したり締結部材を用いて相互に固定したりすることは手間がかかり、ひいては注水ケースの製造性の低下に繋がる。 However, when connecting the parts, placing a sealing member between the parts or fixing them to each other using a fastening member is troublesome, which leads to a decrease in the manufacturability of the water injection case.

特開２０１３－８５５６６号公報JP 2013-85566 A

そこで、分割された部品を組み合わせて構成される注水ケースにおいて、各部品の接続部分の水密性の向上と製造性の向上とを両立させることができる洗濯機の注水ケース、及びその注水ケースを備える洗濯機を提供する。 Therefore, in a water injection case configured by combining divided parts, a water injection case for a washing machine capable of achieving both improvement in watertightness of the connection part of each part and improvement in manufacturability, and the water injection case are provided. Provide a washing machine.

In this case, the right peripheral wall portion 55 has a water supply valve connection portion 551 to which the discharge port of the water supply valve 30 is connected.

また、図５等に示すように、周壁部５２、５３、５４、５５のうち、前側の周壁部５２、後側の周壁部５３、及び左側の周壁部５４は、複数の平坦な領域が各周壁部５２、５３、５４の厚み方向へ向かって交互にずれたような段状に形成されている。すなわち、前側の周壁部５２、後側の周壁部５３、及び左側の周壁部５４は、図５に示すように、平面視においてその壁の厚み方向に凹凸形状となるように形成されている。具体的には、図５に示すように、前側の周壁部５２は、第１領域５２１と第２領域５２２と接続領域５２３とを一体に有して構成されている。本実施形態の場合、前側の周壁部５２は、２つの第１領域５２１と、３つの第２領域５２２と、４つの接続領域５２３と、を一体に有して構成されている。 5 and the like, among the peripheral wall portions 52, 53, 54, and 55, the peripheral wall portion 52 on the front side, the peripheral wall portion 53 on the rear side, and the peripheral wall portion 54 on the left side each have a plurality of flat regions. The peripheral wall portions 52, 53, and 54 are formed in a stepped shape alternately displaced in the thickness direction. That is, as shown in FIG. 5, the front peripheral wall portion 52, the rear peripheral wall portion 53, and the left peripheral wall portion 54 are formed to have uneven shapes in the thickness direction of the walls in plan view. Specifically, as shown in FIG. 5, the front peripheral wall portion 52 is configured by integrally including a first region 521, a second region 522, and a connection region 523. As shown in FIG. In the case of this embodiment, the front peripheral wall portion 52 integrally includes two first regions 521 , three second regions 522 , and four connection regions 523 .

第１領域５２１及び第２領域５２２は、図３及び図５等に示すように、カバー部材５０の上面部５１に対して直角でかつ下方へ延びるように形成されている。第１領域５２１及び第２領域５２２は、共に平坦に形成されて、相互に平行に配置されている。そして、第１領域５２１と第２領域５２２とは、前側の周壁部５２の厚み方向つまり前後方向にずれて設けられている。 The first region 521 and the second region 522 are formed to be perpendicular to the upper surface portion 51 of the cover member 50 and extend downward, as shown in FIGS. 3 and 5 . The first region 521 and the second region 522 are both flat and arranged parallel to each other. The first region 521 and the second region 522 are offset in the thickness direction of the front peripheral wall portion 52, that is, in the front-rear direction.

本実施形態の場合、図５に示すように、第２領域５２２は、第１領域５２１に対して前側に位置している。ここで、前側の周壁部５２の壁面方向を、図５に示す左右方向とする。また、前側の周壁部５２において、第１領域５２１における壁面方向の長さ寸法をＬａ１とし、第２領域５２２における壁面方向の長さ寸法をＬａ２とする。この場合、第２領域５２２における壁面方向の長さ寸法Ｌａ２は、第１領域５２１における壁面方向の長さ寸法Ｌａ１よりも短く設定されている。 In the case of this embodiment, as shown in FIG. 5, the second area 522 is located on the front side with respect to the first area 521 . Here, the wall surface direction of the peripheral wall portion 52 on the front side is the left-right direction shown in FIG. Further, in the peripheral wall portion 52 on the front side, the length dimension in the wall direction in the first region 521 is La1, and the length dimension in the wall direction in the second region 522 is La2. In this case, the length La2 in the wall direction of the second region 522 is set shorter than the length La1 in the wall direction of the first region 521 .

また、図６に示すように、前側の周壁部５２の厚み方向における、第１領域５２１と第２領域５２２とのズレ量Ｄは、第２領域５２２における壁面方向の長さ寸法Ｌａ２よりも短く設定されている。そして、本実施形態の場合、第１領域５２１と第２領域５２２とのズレ量Ｄは、前側の周壁部５２の厚み寸法ｔ以下に設定されている。 Further, as shown in FIG. 6, the amount of deviation D between the first region 521 and the second region 522 in the thickness direction of the front side peripheral wall portion 52 is shorter than the length dimension La2 of the second region 522 in the wall direction. is set. In this embodiment, the amount of deviation D between the first region 521 and the second region 522 is set to be equal to or less than the thickness dimension t of the peripheral wall portion 52 on the front side.

接続領域５２３は、前側の周壁部５２において、第１領域５２１と第２領域５２２との間を接続する領域である。接続領域５２３は、図５等に示すように、前側の周壁部５２の壁面方向つまり左右方向に対して傾斜したテーパ形状に形成されている。この場合、図５等に示すように、第１領域５２１と第２領域５２２とは、平面視において重なっていない。そのため、第１領域５２１の左右両端部に設けられた２つの接続領域５２３は、前方つまり平面視においてカバー部材５０の内側から外側へ向かって拡がるように配置されている。 The connection region 523 is a region that connects the first region 521 and the second region 522 in the front peripheral wall portion 52 . As shown in FIG. 5 and the like, the connection region 523 is formed in a tapered shape that is inclined with respect to the wall surface direction of the front side peripheral wall portion 52, that is, the left-right direction. In this case, as shown in FIG. 5 and the like, the first region 521 and the second region 522 do not overlap in plan view. Therefore, the two connection regions 523 provided at both left and right end portions of the first region 521 are arranged so as to expand from the inside to the outside of the cover member 50 in a front view, that is, in plan view.

It connects with the area 532 . Then, as shown in FIG. 5 and the like, the first region 531 and the second region 532 do not overlap in plan view. Therefore, the two connection regions 523 provided at both left and right end portions of the first region 531 are arranged so as to expand from the inside to the outside of the cover member 50 in the rear, that is, in plan view.

左側の周壁部５４は、１つの第１領域５４１と、１つの第２領域５４２と、１つの接続領域５４３と、を一体に有して構成されている。第１領域５４１及び第２領域５４２は、上述した前側の周壁部５２の各領域５２１、５２２等と同様に、カバー部材５０の上面部５１に対して直角でかつ下方へ延びるように形成されて、かつ平坦に形成されている。そして、第１領域５４１と第２領域５４２とは、相互に平行に配置されていると共に、左側の周壁部５４の厚み方向つまり左右方向にずれて設けられている。 The left peripheral wall portion 54 integrally includes one first region 541 , one second region 542 , and one connection region 543 .

また、カバー部材５０は、図４及び図７に示すように、複数の隔壁部５６を一体に有している。隔壁部５６は、カバー部材５０の内部つまり周壁部５２、５３、５４、５５の内側に設けられており、カバー部材５０の上面部５１に対して直角でかつ下方へ延びるように形成されている。複数の隔壁部５６間は、カバー部材５０の内部を複数に区画している。そして、隔壁部５６間又は、隔壁部５６と周壁部５２、５３、５４、５５との間には、複数の曲がりくねった水路５７が形成されている。この場合、隔壁部５６も、上述した周壁部５２、５３、５４と同様に、複数の平坦な領域が隔壁部５６の厚み方向へ向かって交互にずれたような段状に形成されている。 4 and 7, the cover member 50 integrally has a plurality of partition walls 56. As shown in FIGS. The partition wall portion 56 is provided inside the cover member 50, that is, inside the peripheral wall portions 52, 53, 54, and 55, and is formed to be perpendicular to the upper surface portion 51 of the cover member 50 and extend downward. . The interior of the cover member 50 is partitioned into a plurality of sections between the partition walls 56 . A plurality of meandering water channels 57 are formed between the partitions 56 or between the partitions 56 and the peripheral walls 52 , 53 , 54 , 55 . In this case, like the peripheral wall portions 52 , 53 , and 54 described above, the partition wall portion 56 is also formed in a stepped shape in which a plurality of flat regions are alternately shifted in the thickness direction of the partition wall portion 56 .

すなわち、図７に示すように、隔壁部５６も、第１領域５６１と第２領域５６２と接続領域５６３とを一体に有して構成されている。第１領域５６１及び第２領域５６２は、平坦に形成されており、水路５７内を流れる水の方向に沿って設けられている。この場合、第２領域５６２は、第１領域５６１よりも、カバー部材５０の中央に対して外側に位置している。また、接続領域５６３は、隣接する第１領域５６１と第２領域５６２を接続している。接続領域５６３は、水路５７内を流れる水の方向に対して傾斜したいわゆるテーパ状に形成されている。 That is, as shown in FIG. 7, the partition wall portion 56 also integrally includes a first region 561, a second region 562, and a connection region 563. As shown in FIG. The first region 561 and the second region 562 are formed flat and provided along the direction of water flowing through the channel 57 . In this case, the second area 562 is located outside the center of the cover member 50 relative to the first area 561 . Also, the connection region 563 connects the first region 561 and the second region 562 adjacent to each other. The connection region 563 is formed in a so-called tapered shape that is inclined with respect to the direction of water flowing through the water channel 57 .

ケース部材６０は、注水ケース４０の下側部分を構成する。ケース部材６０は、例えばポリプロピレン等の合成樹脂製の成形品であって、図３に示すように、上面を除く一部この場合前面部が開口した容器状に形成されている。ケース部材６０の前面の開口部６１には、洗剤や柔軟剤を投入するための図示しない引き出し式ケースが出し入れ可能となっている。 The case member 60 constitutes the lower portion of the water injection case 40 . The case member 60 is a molded product made of synthetic resin such as polypropylene, and as shown in FIG. An opening 61 on the front surface of the case member 60 allows a drawer-type case (not shown) to be put in and taken out for putting in detergent and softener.

ケース部材６０は、図３に示すように、複数の貫通穴６３と、突出部６４と、を有している。貫通穴６３は、ケース部材６０の上面部６２を上下方向に貫いて形成されており、ケース部材６０の内部と外部とを連通している。複数の貫通穴６３は、水路５７に沿って配置されている。突出部６４は、上面部６２から上方へ突出し、隔壁部５６の下端部に沿って設けられている。この場合、突出部６４の突出量は、隔壁部５６の厚みよりも小さい。 The case member 60 has a plurality of through holes 63 and protrusions 64, as shown in FIG. The through-hole 63 is formed vertically through the upper surface portion 62 of the case member 60 to communicate the inside and the outside of the case member 60 . A plurality of through holes 63 are arranged along the water channel 57 . The protruding portion 64 protrudes upward from the upper surface portion 62 and is provided along the lower end portion of the partition wall portion 56 . In this case, the protrusion amount of the protruding portion 64 is smaller than the thickness of the partition wall portion 56 .

この構成において、カバー部材５０は、ケース部材６０の上側に溶着されて、カバー部材５０とケース部材６０とが一体的に組み立てられる。具体的には、周壁部５２、５３、５４、５５の下端部及び隔壁部５６の下端部と、突出部６４とを突き合わせた状態で、相互に溶着される。これにより、カバー部材５０とケース部材６０とは、ケース部材６０の貫通穴６３を除いて、水密に接合される。この場合、カバー部材５０とケース部材６０との間にはシール部材は設けられていない。また、この場合、カバー部材５０とケース部材６０とは接合には、ネジ等の締結部材は用いられていない。 In this configuration, the cover member 50 is welded to the upper side of the case member 60 to integrally assemble the cover member 50 and the case member 60 . Specifically, the lower end portions of the peripheral wall portions 52, 53, 54, 55 and the lower end portion of the partition wall portion 56 and the projecting portion 64 are butted against each other and welded to each other. As a result, the cover member 50 and the case member 60 are watertightly joined except for the through hole 63 of the case member 60 . In this case, no sealing member is provided between the cover member 50 and the case member 60 . In this case, the cover member 50 and the case member 60 are joined together without using a fastening member such as a screw.

そして、この構成において、図１に示す給水口２１、２２から注水ケース４０内に流入した水は、カバー部材５０の内側に設けられた水路５７を通り、貫通穴６３からケース部材６０内に流入する。そして、貫通穴６３からケース部材６０内に流入した水は、図示しない引き出し式ケース内に投入されていた洗剤や柔軟剤を溶解した後、開口部６１から水槽１１内に注ぎ込まれる。 In this configuration, water that has flowed into the water injection case 40 from the water supply ports 21 and 22 shown in FIG. do. The water that has flowed into the case member 60 through the through hole 63 dissolves the detergent and softener put into the drawer-type case (not shown), and then pours into the water tub 11 through the opening 61 .

以上説明した実施形態によれば、注水ケース４０は、カバー部材５０と、ケース部材６０と、を備えている。カバー部材５０は、下方が開口した容器状に形成されて、給水弁３０が接続される。ケース部材６０は、上面を除く一部が開口した容器状に形成されて、上側にカバー部材５０が溶着されている。また、カバー部材５０は、周壁部５２、５３、５４、５５と、隔壁部５６と、を有している。周壁部５２、５３、５４、５５は、カバー部材５０の容器状の周囲の壁を形成する。隔壁部５６は、カバー部材５０の内部に設けられており、カバー部材５０の内部を区画して水路５７を形成している。 According to the embodiment described above, the water injection case 40 includes the cover member 50 and the case member 60 . The cover member 50 is formed in the shape of a container with an open bottom, and is connected to the water supply valve 30 . The case member 60 is formed in the shape of a container that is partially open except for the upper surface, and the cover member 50 is welded to the upper side. The cover member 50 also has peripheral wall portions 52 , 53 , 54 , 55 and a partition wall portion 56 . The peripheral wall portions 52 , 53 , 54 , 55 form a container-like peripheral wall of the cover member 50 . The partition wall 56 is provided inside the cover member 50 and partitions the inside of the cover member 50 to form a water channel 57 .

これによれば、注水ケース４０は、上下に二分割したカバー部材５０とケース部材６０とを組み合わせて構成されている。このため、カバー部材５０とケース部材６０とを一体成形した場合に比べて、カバー部材５０及びケース部材６０の金型を比較的単純な構造にすることができ、その結果、注水ケース４０の製造コストの増大を抑制することができる。 According to this, the water injection case 40 is configured by combining the cover member 50 and the case member 60 which are vertically divided into two parts. Therefore, compared to the case where the cover member 50 and the case member 60 are integrally molded, the molds for the cover member 50 and the case member 60 can be formed with a relatively simple structure. An increase in cost can be suppressed.

また、カバー部材５０とケース部材６０とは、シール部材を用いず、また、ネジ等の締結部材を用いることなく、溶着によって相互に水密に接合している。これによれば、カバー部材５０とケース部材６０との間にシール部材を配置したりネジ等の締結部材を用いて相互に固定したりした場合に比べて、注水ケース４０を製造する際の手間を削減することができる。その結果、注水ケース４０の製造性を向上させることができる。 In addition, the cover member 50 and the case member 60 are water-tightly joined to each other by welding without using a sealing member or a fastening member such as a screw. According to this, compared to the case where a seal member is arranged between the cover member 50 and the case member 60 or they are fixed to each other using a fastening member such as a screw, the time and effort required to manufacture the water injection case 40 is reduced. can be reduced. As a result, the manufacturability of the water injection case 40 can be improved.

ここで、カバー部材５０とケース部材６０とは、溶着によって相互に接合されている。この場合、カバー部材５０とケース部材６０との溶着は、カバー部材５０をケース部材６０の上面部６２に一定の押圧力で押し付けた状態で行われる。そのため、周壁部５２、５３、５４、５５及び隔壁部５６を、単純に全体的に平坦な形状とすると、周壁部５２、５３、５４、５５及び隔壁部５６は、カバー部材５０に加わる押圧力つまり上面部５１に対して直角方向に作用する押圧力に抗しきれずに、座屈して変形してしまうおそれがある。 Here, the cover member 50 and the case member 60 are joined together by welding. In this case, the cover member 50 and the case member 60 are welded while the cover member 50 is pressed against the upper surface portion 62 of the case member 60 with a constant pressing force. Therefore, if the peripheral wall portions 52 , 53 , 54 , 55 and the partition wall portion 56 are simply formed into a flat shape as a whole, the peripheral wall portions 52 , 53 , 54 , 55 and the partition wall portion 56 exert a pressing force on the cover member 50 . In other words, there is a risk that the upper surface portion 51 will not be able to resist the pressing force acting in the direction perpendicular to it, and will buckle and deform.

そして、周壁部５２、５３、５４、５５及び隔壁部５６が変形すると、注水ケース４０の意匠性を損なうだけでなく、例えば周壁部５２、５３、５４、５５及び隔壁部５６と、ケース部材６０の上面部６２との間に隙間が生じる可能性がある。すると、注水ケース４０の水密性が低下して、その隙間から水路５７内を通る水が漏れだし、注水ケースとしての機能を果たせないおそれがある。更には、隙間が生じる位置によっては、水路５７を通る水の水圧によってその隙間が拡大するおそれがある。 When the peripheral wall portions 52, 53, 54, 55 and the partition wall portion 56 are deformed, not only does the design of the water injection case 40 deteriorate, but also, for example, the peripheral wall portions 52, 53, 54, 55 and the partition wall portion 56 and the case member 60 are deformed. There is a possibility that a gap may occur between the upper surface portion 62 of the . As a result, the water-tightness of the water injection case 40 is lowered, and the water passing through the water passage 57 leaks through the gap, possibly failing to function as a water injection case. Furthermore, depending on the position of the gap, the water pressure of the water passing through the water channel 57 may expand the gap.

そこで、本実施形態において、周壁部５２、５３、５４、５５及び隔壁部５６のうち少なくとも一方は、第１領域と第２領域とを有している。本実施形態の場合、周壁部５２、５３、５４及び隔壁部５６の両方とも、それぞれ第１領域５２１、５３１、５４１、５６１と第２領域５２２、５３２、５４２、５６２とを有している。第１領域５２１、５３１、５４１、５６１は、カバー部材５０の上面部５１に対して直角方向に延びるように形成されている。第２領域５２２、５３２、５４２、５６２は、カバー部材５０の上面部５１に対して直角方向に延びるように形成され、それぞれの第１領域５２１、５３１、５４１、５６１に対して周壁部５２、５３、５４又は隔壁部５６の厚み方向にずれて設けられている。 Therefore, in this embodiment, at least one of the peripheral wall portions 52, 53, 54, 55 and the partition wall portion 56 has a first region and a second region. In this embodiment, both the peripheral walls 52, 53, 54 and the partition 56 have first regions 521, 531, 541, 561 and second regions 522, 532, 542, 562, respectively. The first regions 521 , 531 , 541 , 561 are formed to extend perpendicularly to the upper surface portion 51 of the cover member 50 . The second regions 522 , 532 , 542 , 562 are formed to extend in a direction perpendicular to the upper surface portion 51 of the cover member 50 . 53 , 54 or the partition wall 56 are provided so as to be displaced in the thickness direction.

これによれば、第１領域５２１、５３１、５４１、５６１と第２領域５２２、５３２、５４２、５６２とを壁の厚み方向にずらして配置することで、上面部５１に対する直角方向への耐荷重性つまり上下方向への耐荷重性を向上させことができる。これにより、カバー部材５０とケース部材６０とを溶着する際に、周壁部５２、５３、５４、５５や隔壁部５６が変形してしまうことを抑制することができる。したがって、カバー部材５０とケース部材６０とを隙間無く高い強度で溶着することができる。この結果、シール部材やネジ等の締結部材を用いることなく、注水ケース４０の水密性を更に向上させることができる。 According to this, by displacing the first regions 521, 531, 541, 561 and the second regions 522, 532, 542, 562 in the thickness direction of the wall, the load resistance in the direction perpendicular to the upper surface portion 51 can be increased. The load resistance in the vertical direction can be improved. As a result, when the cover member 50 and the case member 60 are welded together, deformation of the peripheral wall portions 52, 53, 54, 55 and the partition wall portion 56 can be suppressed. Therefore, the cover member 50 and the case member 60 can be welded with high strength without a gap. As a result, the watertightness of the water injection case 40 can be further improved without using fastening members such as sealing members and screws.

以上より、本実施形態によれば、上下に二分割されたカバー部材５０及びケース部材６０を組み合わせて構成される注水ケース４０において、カバー部材５０とケース部材６０との接続部分の水密性の向上と、製造性の向上と、を両立させることができる。 As described above, according to the present embodiment, in the water injection case 40 configured by combining the cover member 50 and the case member 60 which are divided vertically into two, the watertightness of the connecting portion between the cover member 50 and the case member 60 is improved. and improvement of manufacturability can be made compatible.

ここで、例えば前側の周壁部５２は、他の周壁部５３、５４、５５に比べて面積が大きいため、壁の厚み方向この場合前後方向への剛性が弱くなりがちであり、成形後に反りが生じ易い。そして、周壁部５２に反りが生じると、カバー部材５０とケース部材６０とを溶着する際に、前側の周壁部５２の下端部が突出部６４に密着し難くなって、注水ケース４０の水密性が損なわれる可能性がある。 Here, for example, the peripheral wall portion 52 on the front side has a larger area than the other peripheral wall portions 53, 54, and 55, so the rigidity in the thickness direction of the wall, in this case, the front-rear direction, tends to be weak, and warping occurs after molding. easily occur. If the peripheral wall portion 52 is warped, it becomes difficult for the lower end of the front peripheral wall portion 52 to come into close contact with the projecting portion 64 when the cover member 50 and the case member 60 are welded together. may be damaged.

そこで、本実施形態によれば、前側の周壁部５２について見ると、図５に示すように、第２領域５２２における壁面方向の長さ寸法Ｌａ２は、第１領域５２１における壁面方向の長さ寸法Ｌａ２２よりも短く設定されている。つまり、本実施形態において、周壁部５２は、第１領域５２１と、第１領域５２１よりも短い幅の第２領域５２２とを含んで構成されている。これによれば、前側の周壁部５２は、壁の厚み方向への剛性を高めることができ、成形後に反りが生じることを抑制できる。その結果、カバー部材５０とケース部材６０とを溶着する際に、前側の周壁部５２の下端部が突出部６４に密着し易くなり、注水ケース４０の水密性を向上させることができる。 Therefore, according to the present embodiment, when looking at the front side peripheral wall portion 52, as shown in FIG. It is set shorter than La22. That is, in the present embodiment, the peripheral wall portion 52 includes a first region 521 and a second region 522 having a width shorter than that of the first region 521 . According to this, the peripheral wall portion 52 on the front side can increase the rigidity in the thickness direction of the wall, and can suppress warping after molding. As a result, when the cover member 50 and the case member 60 are welded together, the lower end portion of the front peripheral wall portion 52 is easily brought into close contact with the projecting portion 64, and the watertightness of the water injection case 40 can be improved.

各第１領域５２１、５３１、５４１、５６１及び各第２領域５２２、５３２、５４２、５６２は平坦に形成されている。また、各接続領域５２３、５３３、５４３、５６３は、周壁部５２、５３、５４又は隔壁部５６の壁面方向に対して傾斜したテーパ形状に形成されている。これによれば、水路５７を通る水は、各第１領域５２１、５３１、５４１、５６１、各第２領域５２２、５３２、５４２、５６２、及び各接続領域５２３、５３３、５４３、５６３に沿って滑らかに流れる。このため、各第１領域５２１、５３１、５４１、５６１及び各第２領域５２２、５３２、５４２、５６２や、各接続領域５２３、５３３、５４３、５６３が、水路５７内の水の流れを阻害することを抑制できる。 Each first region 521, 531, 541, 561 and each second region 522, 532, 542, 562 are formed flat. Each connection region 523 , 533 , 543 , 563 is formed in a tapered shape that is inclined with respect to the wall surface direction of the peripheral wall portions 52 , 53 , 54 or the partition wall portion 56 . According to this, water passing through channel 57 flows along each first region 521, 531, 541, 561, each second region 522, 532, 542, 562, and each connection region 523, 533, 543, 563. flow smoothly. Therefore, the first regions 521, 531, 541, 561, the second regions 522, 532, 542, 562, and the connection regions 523, 533, 543, 563 impede the flow of water in the channel 57. can be suppressed.

ここで、周壁部５２、５３、５４について見ると、各第１領域５２１、５３１、５４１と各第２領域５２２、５３２、５４２とのズレ量Ｄは、各第２領域５２２、５３２、５４２の長さ寸法Ｌａ２、Ｌｂ２、Ｌｃ２よりも小さく設定されている。更に、各第１領域５２１、５３１、５４１、５６１と各第２領域５２２、５３２、５４２、５６２とのズレ量Ｄは、各周壁部５２、５３、５４及び隔壁部５６の厚み寸法ｔ以下に設定されている。これによれば、水路５７の幅を確保しつつ、各周壁部５２、５３、５４及び隔壁部５６の強度を効果的に向上させることができる。 Here, looking at the peripheral wall portions 52, 53, 54, the displacement amount D between each of the first regions 521, 531, 541 and each of the second regions 522, 532, 542 is It is set smaller than the length dimensions La2, Lb2 and Lc2. Furthermore, the amount of deviation D between each of the first regions 521, 531, 541, 561 and each of the second regions 522, 532, 542, 562 is less than or equal to the thickness dimension t of each of the peripheral wall portions 52, 53, 54 and the partition wall portion 56. is set. According to this, the strength of each of the peripheral wall portions 52, 53, 54 and the partition wall portion 56 can be effectively improved while ensuring the width of the water channel 57.
