本発明の実施形態は、ドラム式洗濯機に関する。 Embodiments of the present invention relate to a drum-type washing machine.

例えば特許文献１に開示されているように、水槽内に水をシャワー状に噴射する複数の噴射口を備えたドラム式洗濯機が考えられている。 For example, as disclosed in Patent Document 1, a drum-type washing machine having a plurality of injection ports for injecting water into a water tank in a shower shape has been considered.

特開２０１１−２４５２６８号公報Japanese Unexamined Patent Publication No. 2011-245268

この種のドラム式洗濯機は、水槽の前面を構成する水槽カバーの裏面に循環経路を設け、この循環経路を通して、循環ポンプにより水槽内の水を圧送することにより、複数の噴射口から水槽内に水を噴射する構成となっている。ところで、循環経路に複数の噴射口を設ける構成では、各噴射口を循環経路に接続するために、それぞれの噴射口ごとに循環経路を分岐させる必要がある。そのため、この分岐部において、循環経路内を流れる水に圧力損失が生じ、噴射口から噴射される水の水勢が低下してしまうおそれがある。また、この分岐部においては、循環する水に含まれるリントなどの異物が溜まりやすく、従って、溜まった異物により噴射口が塞がれて水勢が低下する、あるいは、水の噴射が困難または不能となるおそれがある。 In this type of drum-type washing machine, a circulation path is provided on the back surface of the water tank cover that constitutes the front surface of the water tank, and water in the water tank is pumped by a circulation pump through this circulation path to enter the water tank from a plurality of injection ports. It is configured to inject water into the water. By the way, in the configuration in which a plurality of injection ports are provided in the circulation path, it is necessary to branch the circulation path for each injection port in order to connect each injection port to the circulation path. Therefore, at this branching portion, a pressure loss may occur in the water flowing in the circulation path, and the water force of the water injected from the injection port may decrease. Further, in this branching portion, foreign matter such as lint contained in the circulating water tends to accumulate, and therefore, the injection port is blocked by the accumulated foreign matter and the water force decreases, or it is difficult or impossible to inject water. There is a risk of becoming.

そこで、水槽内の水を循環させる循環経路に複数の噴射口を設ける構成において、分岐部における水の圧力損失の発生を回避することができ、また、分岐部に異物が溜まってしまうことを回避することができるドラム式洗濯機を提供する。 Therefore, in a configuration in which a plurality of injection ports are provided in the circulation path for circulating water in the water tank, it is possible to avoid the occurrence of water pressure loss at the branch portion and to prevent foreign matter from accumulating at the branch portion. Provide a drum-type washing machine that can be used.

本実施形態に係るドラム式洗濯機は、水槽、循環経路、複数の噴射口、仕切り部を備える。循環経路は、前記水槽内の水を循環させる。噴射口は、前記循環経路に設けられており、それぞれ前記水槽内に水を噴射する。仕切り部は、複数の前記噴射口のうち前記循環経路において最も上流に設けられる最上流噴射口から前記循環経路内を上流側に向かって延びており、前記循環経路内を、前記最上流噴射口に接続する最上流噴射口用循環路と、前記最上流噴射口以外の噴射口である非最上流噴射口に接続する非最上流噴射口用循環路とに仕切る。そして、前記仕切り部は、前記最上流噴射口用循環路および前記非最上流噴射口用循環路を、それぞれ独立した循環路として形成している。 The drum-type washing machine according to the present embodiment includes a water tank, a circulation path, a plurality of injection ports, and a partition. The circulation path circulates the water in the aquarium. The injection ports are provided in the circulation path, and each of them injects water into the water tank. The partition portion extends from the most upstream injection port provided in the circulation path among the plurality of injection ports toward the upstream side in the circulation path, and the most upstream injection port in the circulation path. It is divided into a circulation path for the most upstream injection port connected to the above and a circulation path for a non-upstream injection port connected to a non-upstream injection port which is an injection port other than the most upstream injection port. Then, the partition portion forms the circulation path for the most upstream injection port and the circulation path for the non-upstream injection port as independent circulation paths.

また、洗濯機１０は、給水機構部３０、排水機構部３１、循環機構部３２を備えている。給水機構部３０は、筐体１１の給水口部１１ａから水槽１４の給水口部１４ａに延びる給水経路３０Ｒの途中に給水弁３０ａ、給水ケース３０ｂなどを備えている。給水機構部３０は、ドラム２０内の洗濯物を洗う洗い行程および洗濯物をすすぐすすぎ行程において水槽１４内に水を供給する。給水ケース３０ｂは、図示しない洗剤類投入部を有している。 Further, the washing machine 10 includes a water supply mechanism unit 30, a drainage mechanism unit 31, and a circulation mechanism unit 32. The water supply mechanism unit 30 includes a water supply valve 30a, a water supply case 30b, and the like in the middle of the water supply path 30R extending from the water supply port portion 11a of the housing 11 to the water supply port portion 14a of the water tank 14. The water supply mechanism unit 30 supplies water to the water tank 14 in the washing process of washing the laundry in the drum 20 and the rinsing process of rinsing the laundry. The water supply case 30b has a detergent input section (not shown).

排水機構部３１は、水槽１４の排水口部１４ｂから機外に延びる排水経路３１Ｒの途中に排水弁３１ａなどを備えている。排水機構部３１は、排水行程において水槽１４内の水を機外に排出する。循環機構部３２は、水槽１４の排水口部１４ｂから複数の噴射口１８Ａ，１８Ｂに延びる循環経路３２Ｒの途中に循環ポンプ３２ａなどを備えている。循環機構部３２は、例えば洗い行程やすすぎ行程において循環ポンプ３２ａを駆動することにより、水槽１４内の水を吸い込んで圧送して、複数の噴射口１８Ａ，１８Ｂから水槽１４内にシャワー状に噴射する。即ち、循環機構部３２は、循環経路３２Ｒを通して水槽１４内の水を循環させながら水槽１４内にシャワー状に噴射する。 The drainage mechanism unit 31 is provided with a drainage valve 31a or the like in the middle of the drainage path 31R extending outside the machine from the drainage port portion 14b of the water tank 14. The drainage mechanism unit 31 discharges the water in the water tank 14 to the outside of the machine in the drainage process. The circulation mechanism unit 32 includes a circulation pump 32a and the like in the middle of the circulation path 32R extending from the drainage port portion 14b of the water tank 14 to the plurality of injection ports 18A and 18B. The circulation mechanism unit 32 sucks and pumps the water in the water tank 14 by driving the circulation pump 32a, for example, in the washing stroke and the rinsing stroke, and injects the water into the water tank 14 from the plurality of injection ports 18A and 18B in a shower shape. To do. That is, the circulation mechanism unit 32 injects the water in the water tank 14 in a shower shape while circulating the water in the water tank 14 through the circulation path 32R.

循環経路３２Ｒは、この場合、水槽１４の外部に設けられる外部循環経路３２Ｒａ、および、水槽１４の内部に設けられる内部循環経路３２Ｒｂを有している。外部循環経路３２Ｒａは、水槽１４の外部において、排水口部１４ｂから循環ポンプ３２ａを経由して水槽１４の循環水流入部１４ｃに接続されている。外部循環経路３２Ｒａは、その一部、この場合、水槽１４の排水口部１４ｂから循環ポンプ３２ａまでの部分を排水経路３１Ｒと共用している。一方、図２および図３に例示するように、内部循環経路３２Ｒｂは、水槽１４の内部において、水槽１４の循環水流入部１４ｃから開口部１７の側部に沿って円弧状に延び、当該開口部１７の上部まで延びている。そして、内部循環経路３２Ｒｂは、開口部１７の上部に位置する先端部に複数の噴射口１８Ａ，１８Ｂを備えている。 In this case, the circulation path 32R has an external circulation path 32Ra provided outside the water tank 14 and an internal circulation path 32Rb provided inside the water tank 14. The external circulation path 32Ra is connected to the circulating water inflow portion 14c of the water tank 14 from the drain port portion 14b via the circulation pump 32a outside the water tank 14. The external circulation path 32Ra shares a part thereof, in this case, a portion from the drain port portion 14b of the water tank 14 to the circulation pump 32a with the drainage path 31R. On the other hand, as illustrated in FIGS. 2 and 3, the internal circulation path 32Rb extends in an arc shape from the circulating water inflow portion 14c of the water tank 14 along the side portion of the opening 17 inside the water tank 14, and the opening thereof. It extends to the top of the portion 17. The internal circulation path 32Rb is provided with a plurality of injection ports 18A and 18B at the tip portion located above the opening 17.

次に、複数の噴射口１８Ａ，１８Ｂおよびその周辺部分の構成例について、さらに詳細に説明する。図２および図３に例示するように、複数の噴射口１８Ａ，１８Ｂは、何れも水槽カバー１６の後面に設けられている。噴射口１８Ａ，１８Ｂは、何れも、水槽カバー１６を裏面側から見て、当該水槽カバー１６を上下方向に２分する中心線Ｌ１よりも上側に設けられている。また、噴射口１８Ａ，１８Ｂは、水槽カバー１６を裏面側から見て、当該水槽カバー１６を左右方向に２分する中心線Ｌ２を挟んで左右にほぼ対称に設けられており、それぞれ水槽カバー１６の中心に向かって指向している。噴射口１８Ａ，１８Ｂは、何れも、循環機構部３２の一部を構成する内部循環経路３２Ｒｂに連結されている。内部循環経路３２Ｒｂは、水槽カバー１６の開口部１７の開口形状に沿って、当該開口部１７の一方の側部および上部を通るように円弧状に延びている。 Next, a configuration example of the plurality of injection ports 18A and 18B and their peripheral portions will be described in more detail. As illustrated in FIGS. 2 and 3, the plurality of injection ports 18A and 18B are all provided on the rear surface of the water tank cover 16. The injection ports 18A and 18B are both provided above the center line L1 that divides the water tank cover 16 into two in the vertical direction when the water tank cover 16 is viewed from the back surface side. Further, the injection ports 18A and 18B are provided substantially symmetrically to the left and right with the center line L2 that divides the water tank cover 16 into two in the left-right direction when the water tank cover 16 is viewed from the back surface side. Oriented towards the center of. Both the injection ports 18A and 18B are connected to the internal circulation path 32Rb that forms a part of the circulation mechanism unit 32. The internal circulation path 32Rb extends in an arc shape along the opening shape of the opening 17 of the water tank cover 16 so as to pass through one side portion and the upper portion of the opening 17.

循環機構部３２により循環される水は、外部循環経路３２Ｒａから循環水流入部１４ｃを通して内部循環経路３２Ｒｂに流入し、さらに、この内部循環経路３２Ｒｂを通って２つの噴射口１８Ａ，１８Ｂから水槽１４内にシャワー状に噴射される。噴射口１８Ａ，１８Ｂの先端部は、何れも、水槽１４の内部、この場合、後方下部に向かって滑らかに傾斜している。よって、噴射口１８Ａ，１８Ｂから噴射される水は、当該噴射口１８Ａ，１８Ｂの先端部の形状にガイドされながら水槽１４内部の後方下部に向かうようになる。 The water circulated by the circulation mechanism section 32 flows from the external circulation path 32Ra through the circulating water inflow section 14c into the internal circulation path 32Rb, and further passes through the internal circulation path 32Rb from the two injection ports 18A and 18B to the water tank 14 It is sprayed inside like a shower. The tips of the injection ports 18A and 18B are both smoothly inclined toward the inside of the water tank 14, in this case, the lower rear part. Therefore, the water jetted from the injection ports 18A and 18B goes toward the lower rear part inside the water tank 14 while being guided by the shape of the tip portions of the injection ports 18A and 18B.

ここで、本実施形態では、循環水流入部１４ｃは、水槽カバー１６を裏面側から見て当該水槽カバー１６を上下方向に２分する中心線Ｌ１よりも下側、且つ、水槽カバー１６を裏面側から見て当該水槽カバー１６を左右方向に２分する中心線Ｌ２よりも右側に設けられている。循環水流入部１４ｃは、外部循環経路３２Ｒａと内部循環経路３２Ｒｂとを接続する接続部分の一例であり、この場合、上下方向に延びる筒状をなしている。 Here, in the present embodiment, the circulating water inflow portion 14c is below the center line L1 that divides the water tank cover 16 into two in the vertical direction when the water tank cover 16 is viewed from the back side, and the water tank cover 16 is on the back side. When viewed from the side, the water tank cover 16 is provided on the right side of the center line L2 that divides the water tank cover 16 into two in the left-right direction. The circulating water inflow portion 14c is an example of a connecting portion that connects the external circulation path 32Ra and the internal circulation path 32Rb, and in this case, has a tubular shape extending in the vertical direction.

そして、本実施形態では、循環経路３２Ｒの一部である内部循環経路３２Ｒｂにおいて、循環水は、基端部側である循環水流入部１４ｃ側から供給されて、先端部側である噴射口１８Ａ，１８Ｂ側に向かって流れる。よって、内部循環経路３２Ｒｂにおいて、基端部側である循環水流入部１４ｃ側は循環方向の上流側、先端部側である噴射口１８Ａ，１８Ｂ側は循環方向の下流側となる。 Then, in the present embodiment, in the internal circulation path 32Rb which is a part of the circulation path 32R, the circulating water is supplied from the circulating water inflow portion 14c side which is the base end side, and the injection port 18A which is the tip end side. , Flows toward the 18B side. Therefore, in the internal circulation path 32Rb, the circulating water inflow portion 14c side on the base end side is the upstream side in the circulation direction, and the injection ports 18A and 18B on the tip end side are on the downstream side in the circulation direction.

そして、本実施形態において、２つの噴射口１８Ａ，１８Ｂのうち、循環経路３２Ｒの最も上流側に設けられている噴射口は噴射口１８Ｂである。よって、本実施形態において、噴射口１８Ｂは、循環経路において最も上流側に設けられる最上流噴射口の一例として定義することができる。一方、本実施形態において、２つの噴射口１８Ａ，１８Ｂのうち、循環経路３２Ｒの最も下流側に設けられている噴射口は噴射口１８Ａである。よって、本実施形態において、噴射口１８Ａは、循環経路において最も下流側に設けられる最下流噴射口の一例として定義することができ、また、最上流噴射口以外の噴射口である非最上流噴射口の一例としても定義することができる。 In the present embodiment, of the two injection ports 18A and 18B, the injection port provided on the most upstream side of the circulation path 32R is the injection port 18B. Therefore, in the present embodiment, the injection port 18B can be defined as an example of the most upstream injection port provided on the most upstream side in the circulation path. On the other hand, in the present embodiment, of the two injection ports 18A and 18B, the injection port provided on the most downstream side of the circulation path 32R is the injection port 18A. Therefore, in the present embodiment, the injection port 18A can be defined as an example of the most downstream injection port provided on the most downstream side in the circulation path, and the non-upstream injection which is an injection port other than the most upstream injection port. It can also be defined as an example of the mouth.

そして、循環経路３２Ｒの内部、この場合、内部循環経路３２Ｒｂの内部には、仕切り部の一例であるリブ４０が設けられている。リブ４０は、最上流噴射口の一例である噴射口１８Ｂの先端側つまり下流側のコーナー部１８ｃから水槽１４の径方向外側に向かって延び、その後、内部循環経路３２Ｒｂ内において滑らかに屈曲して当該内部循環経路３２Ｒｂ内を上流側つまり循環水流入部１４ｃ側に向かって延びている。そして、リブ４０は、循環水流入部１４ｃの下流部において水槽１４の径方向外側に向かって滑らかに屈曲して当該循環水流入部１４ｃに接続されている。即ち、リブ４０は、噴射口１８Ｂから内部循環経路３２Ｒｂ内を上流側に向かって循環水流入部１４ｃまで延びている。 A rib 40, which is an example of the partition portion, is provided inside the circulation path 32R, in this case, inside the internal circulation path 32Rb. The rib 40 extends from the corner portion 18c on the tip end side, that is, the downstream side of the injection port 18B, which is an example of the most upstream injection port, toward the radial outer side of the water tank 14, and then smoothly bends in the internal circulation path 32Rb. The inside of the internal circulation path 32Rb extends toward the upstream side, that is, the circulating water inflow portion 14c side. The rib 40 is smoothly bent outward in the radial direction of the water tank 14 at the downstream portion of the circulating water inflow portion 14c and is connected to the circulating water inflow portion 14c. That is, the rib 40 extends from the injection port 18B in the internal circulation path 32Rb toward the upstream side to the circulating water inflow portion 14c.

また、リブ４０は、その全体が水槽１４の軸方向に沿う壁面を構成しており、内部循環経路３２Ｒｂ内において、当該内部循環経路３２Ｒｂの湾曲形状に沿うようにして湾曲している。これにより、リブ４０は、内部循環経路３２Ｒｂ内を、最上流噴射口用循環路４１ａおよび最下流噴射口用循環路４１ｂに仕切っている。 Further, the rib 40 as a whole constitutes a wall surface along the axial direction of the water tank 14, and is curved in the internal circulation path 32Rb so as to follow the curved shape of the internal circulation path 32Rb. As a result, the rib 40 partitions the inside of the internal circulation path 32Rb into the circulation path 41a for the most upstream injection port and the circulation path 41b for the most downstream injection port.

最上流噴射口用循環路４１ａは、内部循環経路３２Ｒｂ内を、循環水流入部１４ｃから下流側に向かって延び、最上流噴射口の一例である噴射口１８Ｂに接続する循環路を構成している。最上流噴射口用循環路４１ａは、内部循環経路３２Ｒｂの湾曲形状に沿うようにして湾曲している。また、最上流噴射口用循環路４１ａは、水槽１４の径方向に沿う幅寸法が、その全長にわたってほぼ一定である水路を構成している。 The circulation path 41a for the most upstream injection port constitutes a circulation path extending in the internal circulation path 32Rb from the circulating water inflow portion 14c toward the downstream side and connecting to the injection port 18B which is an example of the most upstream injection port. There is. The circulation path 41a for the most upstream injection port is curved so as to follow the curved shape of the internal circulation path 32Rb. Further, the circulation path 41a for the uppermost flow injection port constitutes a water channel in which the width dimension along the radial direction of the water tank 14 is substantially constant over the entire length thereof.

一方、最下流噴射口用循環路４１ｂは、内部循環経路３２Ｒｂ内を、循環水流入部１４ｃから下流側に向かって延び、最下流噴射口および非最上流噴射口の一例である噴射口１８Ａに接続する循環路を構成している。最下流噴射口用循環路４１ｂは、内部循環経路３２Ｒｂの湾曲形状に沿うようにして湾曲している。また、最下流噴射口用循環路４１ｂは、水槽１４の径方向に沿う幅寸法が、最上流噴射口用循環路４１ａの先端部を超える下流側において、最上流噴射口用循環路４１ａの先端部を超えない上流側よりも拡大する水路を構成している。 On the other hand, the circulation path 41b for the most downstream injection port extends in the internal circulation path 32Rb from the circulating water inflow portion 14c toward the downstream side, and reaches the most downstream injection port and the injection port 18A which is an example of the non-upstream injection port. It constitutes a connecting circulation path. The circulation path 41b for the most downstream injection port is curved so as to follow the curved shape of the internal circulation path 32Rb. Further, the most downstream injection port circulation path 41b is located on the downstream side where the width dimension along the radial direction of the water tank 14 exceeds the tip end portion of the most upstream injection port circulation path 41a, and the tip of the most upstream injection port circulation path 41a. It constitutes a waterway that expands more than the upstream side that does not exceed the part.

循環水流入部１４ｃから内部循環経路３２Ｒｂ内に流入する循環水Ｗは、リブ４０の上流側の端部つまり循環水流入部１４ｃに接続されている端部により分断され、一方は、矢印ｗ１で例示するように、最上流噴射口用循環路４１ａを通して噴射口１８Ｂから水槽１４内に噴射され、他方は、矢印ｗ２で例示するように、最下流噴射口用循環路４１ｂを通して噴射口１８Ａから水槽１４内に噴射される。 The circulating water W flowing from the circulating water inflow portion 14c into the internal circulation path 32Rb is divided by the upstream end of the rib 40, that is, the end connected to the circulating water inflow portion 14c, and one of them is indicated by an arrow w1. As illustrated, the water is injected into the water tank 14 from the injection port 18B through the circulation path 41a for the most upstream injection port, and the other is injected from the injection port 18A through the circulation path 41b for the most downstream injection port as illustrated by the arrow w2. It is injected into 14.

本実施形態に係る洗濯機１０によれば、循環経路３２Ｒの内部、この場合、水槽１４内に設けられる内部循環経路３２Ｒｂの内部において、リブ４０は、循環水Ｗの循環方向における最も上流側に設けられる噴射口１８Ｂから内部循環経路３２Ｒｂ内を上流側に向かって延びており、内部循環経路３２Ｒｂ内を、噴射口１８Ｂに接続する最上流噴射口用循環路４１ａおよび噴射口１８Ａに接続する最下流噴射口用循環路４１ｂに仕切っている。 According to the washing machine 10 according to the present embodiment, inside the circulation path 32R, in this case, inside the internal circulation path 32Rb provided in the water tank 14, the rib 40 is located on the most upstream side in the circulation direction of the circulating water W. The internal circulation path 32Rb extends from the provided injection port 18B toward the upstream side, and the inside of the internal circulation path 32Rb is connected to the most upstream injection port circulation path 41a and the injection port 18A connected to the injection port 18B. It is partitioned into a circulation path 41b for the downstream injection port.

即ち、水槽１４内の水を循環させる循環経路３２Ｒに複数の噴射口１８Ａ，１８Ｂを設ける構成において、循環経路３２Ｒ内をリブ４０により仕切ることで、複数の噴射口１８Ａ，１８Ｂにそれぞれ接続する専用の循環路を設けるようにした。この構成によれば、従来構成で課題となっていた「分岐部」を設けなくとも、複数の噴射口１８Ａ，１８Ｂにそれぞれ循環水を供給することができる。よって、「分岐部」における水の圧力損失の発生を懸念する必要が無く、また、「分岐部」に異物が溜まってしまうことを懸念する必要も無い。 That is, in a configuration in which a plurality of injection ports 18A and 18B are provided in the circulation path 32R for circulating water in the water tank 14, the inside of the circulation path 32R is partitioned by ribs 40 to connect to the plurality of injection ports 18A and 18B, respectively. The circulation path was set up. According to this configuration, circulating water can be supplied to the plurality of injection ports 18A and 18B, respectively, without providing the "branch portion" which has been a problem in the conventional configuration. Therefore, there is no need to worry about the occurrence of water pressure loss at the "branch portion", and there is no need to worry about foreign matter accumulating at the "branch portion".

また、洗濯機１０によれば、内部循環経路３２Ｒｂ内において、リブ４０は、その全体が水槽１４の軸方向に沿う壁面を構成している。この構成によれば、内部循環経路３２Ｒｂ内をリブ４０により確実に仕切ることができ、最上流噴射口用循環路４１ａおよび最下流噴射口用循環路４１ｂを、それぞれ独立した各噴射口専用の循環路として形成することができる。なお、リブ４０は、水槽１４の軸方向に対し傾斜した構成としてもよい。 Further, according to the washing machine 10, in the internal circulation path 32Rb, the rib 40 as a whole constitutes a wall surface along the axial direction of the water tank 14. According to this configuration, the inside of the internal circulation path 32Rb can be reliably partitioned by the rib 40, and the circulation path 41a for the most upstream injection port and the circulation path 41b for the most downstream injection port can be circulated independently for each injection port. It can be formed as a road. The rib 40 may be configured to be inclined with respect to the axial direction of the water tank 14.

また、洗濯機１０によれば、内部循環経路３２Ｒｂ内において、リブ４０は、噴射口１８Ｂから上流側に向かって循環水流入部１４ｃまで延びている。即ち、リブ４０は、内部循環経路３２Ｒｂ内への循環水Ｗの入口となる部分から設けられているので、内部循環経路３２Ｒｂ内に流入する循環水Ｗを、その入口部分において最上流噴射口用循環路４１ａ側および最下流噴射口用循環路４１ｂ側に確実に分断することができる。よって、最上流噴射口用循環路４１ａを通して循環水Ｗを噴射口１８Ｂに安定的に導くことができ、また、最下流噴射口用循環路４１ｂを通して循環水Ｗを噴射口１８Ａに安定的に導くことができる。 Further, according to the washing machine 10, in the internal circulation path 32Rb, the rib 40 extends from the injection port 18B toward the upstream side to the circulating water inflow portion 14c. That is, since the rib 40 is provided from the portion serving as the inlet of the circulating water W into the internal circulation path 32Rb, the circulating water W flowing into the internal circulation path 32Rb is used for the most upstream injection port at the inlet portion. It can be reliably divided into the circulation path 41a side and the circulation path 41b side for the most downstream injection port. Therefore, the circulating water W can be stably guided to the injection port 18B through the circulation path 41a for the most upstream injection port, and the circulating water W can be stably guided to the injection port 18A through the circulation path 41b for the most downstream injection port. be able to.

In this embodiment, the partition portion is not in the axial direction of the water tank but in the radial direction. That is, as illustrated in FIGS. 4 and 5, the washing machine 10 includes a plurality of washing machines 10, in this case, two water injection covers 19A and 19B. The water injection cover 19A is a water injection cover extending from the base end portion of the internal circulation path 32Rb, that is, the end portion on the circulating water inflow portion 14c side to the tip portion, that is, the end portion on the injection port 18A side, and corresponds to the total length of the internal circulation path 32Rb. It is provided. As illustrated in FIGS. 6 and 7, the water injection cover 19A has a side wall surface 19Aa along the axial direction of the water tank 14 and a partition wall surface 19Ab along the radial direction of the water tank 14.

一方、注水カバー１９Ｂは、内部循環経路３２Ｒｂの基端部つまり循環水流入部１４ｃ側の端部から噴射口１８Ｂにわたる注水カバーであり、内部循環経路３２Ｒｂの一部に対応して設けられている。注水カバー１９Ｂは、水槽１４の軸方向に沿う側壁面１９Ｂａおよび水槽１４の径方向に沿う仕切り壁面１９Ｂｂを有している。 On the other hand, the water injection cover 19B is a water injection cover extending from the base end portion of the internal circulation path 32Rb, that is, the end portion on the circulating water inflow portion 14c side to the injection port 18B, and is provided corresponding to a part of the internal circulation path 32Rb. .. The water injection cover 19B has a side wall surface 19Ba along the axial direction of the water tank 14 and a partition wall surface 19Bb along the radial direction of the water tank 14.

図５に例示するように、水槽カバー１６の裏面には、まず注水カバー１９Ｂが取り付けられる。これにより、循環水流入部１４ｃから噴射口１８Ｂに接続する最上流噴射口用循環路１４１ａが形成される。そして、その注水カバー１９Ｂの裏面側に、さらに注水カバー１９Ａが取り付けられる。これにより、循環水流入部１４ｃから噴射口１８Ａに接続する最下流噴射口用循環路１４１ｂが形成される。 As illustrated in FIG. 5, a water injection cover 19B is first attached to the back surface of the water tank cover 16. As a result, the circulation path 141a for the most upstream injection port is formed, which connects the circulating water inflow portion 14c to the injection port 18B. Then, the water injection cover 19A is further attached to the back surface side of the water injection cover 19B. As a result, the most downstream injection port circulation path 141b that connects the circulating water inflow portion 14c to the injection port 18A is formed.

即ち、本実施形態の洗濯機１０によれば、注水カバー１９Ｂの側壁面１９Ｂａ、注水カバー１９Ａの側壁面１９Ａａ、注水カバー１９Ａの仕切り壁面１９Ａｂにより、循環経路３２Ｒの一部、この場合、水槽１４の内部に設けられる内部循環経路３２Ｒｂが構成される。そして、この内部循環経路３２Ｒｂの内部が注水カバー１９Ｂの仕切り壁面１９Ｂｂにより仕切られることによって、内部循環経路３２Ｒｂの内部に、最上流噴射口用循環路１４１ａおよび最下流噴射口用循環路１４１ｂが形成された構成となっている。 That is, according to the washing machine 10 of the present embodiment, a part of the circulation path 32R, in this case, the water tank 14 is provided by the side wall surface 19Ba of the water injection cover 19B, the side wall surface 19Aa of the water injection cover 19A, and the partition wall surface 19Ab of the water injection cover 19A. The internal circulation path 32Rb provided inside the above is configured. Then, the inside of the internal circulation path 32Rb is partitioned by the partition wall surface 19Bb of the water injection cover 19B, so that the circulation path 141a for the most upstream injection port and the circulation path 141b for the most downstream injection port are formed inside the internal circulation path 32Rb. It has become a structure.

上述した第１実施形態では、最上流噴射口用循環路４１ａおよび最下流噴射口用循環路４１ｂが内部循環経路３２Ｒｂ内において水槽１４の径方向に沿って併設されている構成を例示した。これに対して、本実施形態では、最上流噴射口用循環路１４１ａおよび最下流噴射口用循環路１４１ｂが内部循環経路３２Ｒｂ内において水槽１４の軸方向に沿って併設されている構成を例示している。 In the above-described first embodiment, the configuration in which the circulation path 41a for the most upstream injection port and the circulation path 41b for the most downstream injection port are provided side by side in the internal circulation path 32Rb along the radial direction of the water tank 14 is illustrated. On the other hand, in the present embodiment, a configuration in which the circulation path 141a for the most upstream injection port and the circulation path 141b for the most downstream injection port are provided along the axial direction of the water tank 14 in the internal circulation path 32Rb is illustrated. ing.

注水カバー１９Ｂの仕切り壁面１９Ｂｂは、内部循環経路３２Ｒｂの内部を最上流噴射口用循環路１４１ａおよび最下流噴射口用循環路１４１ｂに仕切る仕切り部の一例として機能する。そして、注水カバー１９Ｂの仕切り壁面１９Ｂｂは、噴射口１８Ｂの先端側のコーナー部１８ｃから内部循環経路３２Ｒｂ内を滑らかに屈曲しながら上流側つまり循環水流入部１４ｃ側に向かって延びており、循環水流入部１４ｃに接続されている。 The partition wall surface 19Bb of the water injection cover 19B functions as an example of a partition portion that partitions the inside of the internal circulation path 32Rb into the circulation path 141a for the most upstream injection port and the circulation path 141b for the most downstream injection port. The partition wall surface 19Bb of the water injection cover 19B extends from the corner portion 18c on the tip end side of the injection port 18B toward the upstream side, that is, the circulating water inflow portion 14c side while smoothly bending in the internal circulation path 32Rb, and circulates. It is connected to the water inflow section 14c.

本実施形態においても、最上流噴射口用循環路１４１ａは、内部循環経路３２Ｒｂ内を、循環水流入部１４ｃから下流側に向かって延び、最上流噴射口の一例である噴射口１８Ｂに接続する循環路を構成している。また、最上流噴射口用循環路１４１ａは、内部循環経路３２Ｒｂの湾曲形状に沿うようにして湾曲している。一方、最下流噴射口用循環路１４１ｂは、内部循環経路３２Ｒｂ内を、循環水流入部１４ｃから下流側に向かって延び、最下流噴射口および非最上流噴射口の一例である噴射口１８Ａに接続する循環路を構成している。また、最下流噴射口用循環路１４１ｂは、内部循環経路３２Ｒｂの湾曲形状に沿うようにして湾曲している。 Also in the present embodiment, the circulation path 141a for the most upstream injection port extends in the internal circulation path 32Rb toward the downstream side from the circulating water inflow portion 14c and is connected to the injection port 18B which is an example of the most upstream injection port. It constitutes a circulation path. Further, the circulation path 141a for the uppermost flow injection port is curved so as to follow the curved shape of the internal circulation path 32Rb. On the other hand, the circulation path 141b for the most downstream injection port extends in the internal circulation path 32Rb from the circulating water inflow portion 14c toward the downstream side, and reaches the most downstream injection port and the injection port 18A which is an example of the non-upstream injection port. It constitutes a connecting circulation path. Further, the circulation path 141b for the most downstream injection port is curved so as to follow the curved shape of the internal circulation path 32Rb.

図７に例示するように、循環水流入部１４ｃから内部循環経路３２Ｒｂ内に流入する循環水Ｗは、注水カバー１９Ｂの仕切り壁面１９Ｂｂの上流側の端部つまり循環水流入部１４ｃに接続されている端部により分断され、一方は、矢印ｗ１で例示するように、最上流噴射口用循環路１４１ａを通して噴射口１８Ｂから水槽１４内に噴射され、他方は、矢印ｗ２で例示するように、最下流噴射口用循環路１４１ｂを通して噴射口１８Ａから水槽１４内に噴射される。 As illustrated in FIG. 7, the circulating water W flowing into the internal circulation path 32Rb from the circulating water inflow portion 14c is connected to the upstream end of the partition wall surface 19Bb of the water injection cover 19B, that is, the circulating water inflow portion 14c. One is injected into the water tank 14 from the injection port 18B through the circulation path 141a for the most upstream injection port as illustrated by the arrow w1, and the other is the most as illustrated by the arrow w2. It is injected into the water tank 14 from the injection port 18A through the circulation path 141b for the downstream injection port.

本実施形態に係る洗濯機１０によっても、水槽１４内を循環させる循環経路３２Ｒに複数の噴射口１８Ａ，１８Ｂを設ける構成において、循環経路３２Ｒ内を注水カバー１９Ｂの仕切り壁面１９Ｂｂにより仕切ることで、複数の噴射口１８Ａ，１８Ｂにそれぞれ接続する専用の循環路を設けるようにした。そのため、従来構成で課題となっていた「分岐部」を設けなくとも、複数の噴射口１８Ａ，１８Ｂにそれぞれ循環水Ｗを供給することができる。よって、「分岐部」における水の圧力損失の発生を懸念する必要が無く、また、「分岐部」に異物が溜まってしまうことを懸念する必要も無い。 Also in the washing machine 10 according to the present embodiment, in a configuration in which a plurality of injection ports 18A and 18B are provided in the circulation path 32R that circulates in the water tank 14, the inside of the circulation path 32R is partitioned by the partition wall surface 19Bb of the water injection cover 19B. Dedicated circulation paths are provided to connect to the plurality of injection ports 18A and 18B, respectively. Therefore, the circulating water W can be supplied to the plurality of injection ports 18A and 18B, respectively, without providing the "branch portion" which has been a problem in the conventional configuration. Therefore, there is no need to worry about the occurrence of water pressure loss at the "branch portion", and there is no need to worry about foreign matter accumulating at the "branch portion".

また、洗濯機１０によれば、内部循環経路３２Ｒｂ内において、注水カバー１９Ｂの仕切り壁面１９Ｂｂは、その全体が水槽１４の径方向に沿う壁面を構成している。この構成によれば、内部循環経路３２Ｒｂ内を注水カバー１９Ｂの仕切り壁面１９Ｂｂにより確実に仕切ることができ、最上流噴射口用循環路１４１ａおよび最下流噴射口用循環路１４１ｂを、それぞれ独立した各噴射口専用の循環路として形成することができる。なお、注水カバー１９Ｂの仕切り壁面１９Ｂｂは、水槽１４の径方向に対し傾斜した構成としてもよい。 Further, according to the washing machine 10, in the internal circulation path 32Rb, the partition wall surface 19Bb of the water injection cover 19B as a whole constitutes a wall surface along the radial direction of the water tank 14. According to this configuration, the inside of the internal circulation path 32Rb can be reliably partitioned by the partition wall surface 19Bb of the water injection cover 19B, and the circulation path 141a for the most upstream injection port and the circulation path 141b for the most downstream injection port are independent of each other. It can be formed as a circulation path dedicated to the injection port. The partition wall surface 19Bb of the water injection cover 19B may be configured to be inclined with respect to the radial direction of the water tank 14.

また、洗濯機１０によれば、内部循環経路３２Ｒｂ内において、注水カバー１９Ｂの仕切り壁面１９Ｂｂは、噴射口１８Ｂから上流側に向かって循環水流入部１４ｃまで延びている。即ち、注水カバー１９Ｂの仕切り壁面１９Ｂｂは、内部循環経路３２Ｒｂ内への循環水の入口となる部分から設けられているので、内部循環経路３２Ｒｂ内に流入する循環水Ｗを、その入口部分にて最上流噴射口用循環路１４１ａ側および最下流噴射口用循環路１４１ｂ側に確実に分断することができる。よって、最上流噴射口用循環路１４１ａを通して循環水Ｗを噴射口１８Ｂに安定的に導くことができ、また、最下流噴射口用循環路１４１ｂを通して循環水Ｗを噴射口１８Ａに安定的に導くことができる。 Further, according to the washing machine 10, in the internal circulation path 32Rb, the partition wall surface 19Bb of the water injection cover 19B extends from the injection port 18B toward the upstream side to the circulating water inflow portion 14c. That is, since the partition wall surface 19Bb of the water injection cover 19B is provided from the portion serving as the inlet of the circulating water into the internal circulation path 32Rb, the circulating water W flowing into the internal circulation path 32Rb is introduced at the inlet portion. It can be reliably divided into the circulation path 141a side for the most upstream injection port and the circulation path 141b side for the most downstream injection port. Therefore, the circulating water W can be stably guided to the injection port 18B through the circulation path 141a for the most upstream injection port, and the circulating water W can be stably guided to the injection port 18A through the circulation path 141b for the most downstream injection port. be able to.

（第３実施形態）
図８に例示するように、本実施形態の洗濯機１０は、第１実施形態に例示した洗濯機１０において、さらに水量調整部５０を備える。水量調整部５０は、リブ４０の基端部つまり循環水流入部１４ｃに接続する端部に設けられている。水量調整部５０は、回動片部５０ａが回動軸５０ｂを中心に、矢印Ａ１，Ａ２方向に回動可能に設けられた構成となっている。水量調整部５０は、例えばモータなどにより構成される図示しない駆動部により回動片部５０ａを回動させる構成としてもよいし、例えば洗濯機１０の使用者や製造者が手動により回動片部５０ａを回動させる構成としてもよい。 (Third Embodiment)
As illustrated in FIG. 8, the washing machine 10 of the present embodiment further includes a water amount adjusting unit 50 in the washing machine 10 illustrated in the first embodiment. The water amount adjusting portion 50 is provided at the base end portion of the rib 40, that is, the end portion connected to the circulating water inflow portion 14c. The water amount adjusting portion 50 has a configuration in which a rotating piece portion 50a is provided so as to be rotatable in the directions of arrows A1 and A2 around a rotating shaft 50b. The water amount adjusting unit 50 may be configured to rotate the rotating piece portion 50a by a drive unit (not shown) composed of, for example, a motor, or the rotating piece unit 50 may be manually rotated by, for example, a user or a manufacturer of the washing machine 10. It may be configured to rotate 50a.

回動片部５０ａを、最上流噴射口用循環路４１ａ側である矢印Ａ１側に回動させることにより、最上流噴射口用循環路４１ａへの循環水Ｗの流入量を減らし、最下流噴射口用循環路４１ｂへの循環水Ｗの流入量を増やすことができる。一方、回動片部５０ａを、最下流噴射口用循環路４１ｂ側である矢印Ａ２側に回動させることにより、最下流噴射口用循環路４１ｂへの循環水Ｗの流入量を減らし、最上流噴射口用循環路４１ａへの循環水Ｗの流入量を増やすことができる。即ち、水量調整部５０は、回動片部５０ａの回動位置を調整することにより、最上流噴射口用循環路４１ａへの循環水Ｗの流入量および最下流噴射口用循環路４１ｂへの循環水Ｗの流入量を調整可能に構成されている。 By rotating the rotating piece 50a toward the arrow A1 side, which is the circulation path 41a side for the most upstream injection port, the inflow amount of the circulating water W into the circulation path 41a for the most upstream injection port is reduced, and the most downstream injection is performed. The amount of circulating water W flowing into the oral circulation passage 41b can be increased. On the other hand, by rotating the rotating piece 50a toward the arrow A2 side, which is the circulation path 41b side for the most downstream injection port, the inflow amount of the circulating water W into the circulation path 41b for the most downstream injection port is reduced, and the maximum amount is reduced. The inflow amount of the circulating water W into the circulation path 41a for the upstream injection port can be increased. That is, by adjusting the rotation position of the rotating piece portion 50a, the water amount adjusting unit 50 adjusts the inflow amount of the circulating water W into the circulation path 41a for the most upstream injection port and the circulation path 41b for the most downstream injection port. The inflow amount of the circulating water W can be adjusted.

本実施形態に係る洗濯機１０によれば、回動片部５０ａの回動位置を調整することにより、最上流噴射口用循環路４１ａに供給される循環水量つまり噴射口１８Ｂから噴射される噴射水量および最下流噴射口用循環路４１ｂに供給される循環水量つまり噴射口１８Ａから噴射される噴射水量を調整することができる。 According to the washing machine 10 according to the present embodiment, the amount of circulating water supplied to the circulation path 41a for the most upstream injection port, that is, the injection injected from the injection port 18B, is performed by adjusting the rotation position of the rotating piece portion 50a. The amount of water and the amount of circulating water supplied to the most downstream injection port circulation path 41b, that is, the amount of injected water injected from the injection port 18A can be adjusted.

ここで、洗濯機１０を、噴射口１８Ａ，１８Ｂの先端部が指向する方向を相互に異ならせた構成とすれば、つまり、例えば噴射口１８Ａ，１８Ｂの一方を水槽１４内部の前方下部、他方を水槽１４内の後方下部に指向させた構成とすれば、回動片部５０ａの回動位置を調整することにより、水槽１４内部の前方下部に噴射される噴射水量および水槽１４内部の後方下部に噴射される噴射水量を異ならせることができる。 Here, if the washing machine 10 has a configuration in which the directions of the tips of the injection ports 18A and 18B are different from each other, that is, for example, one of the injection ports 18A and 18B is the lower front part inside the water tank 14, and the other. Is configured to be directed toward the rear lower part in the water tank 14, the amount of jet water injected into the front lower part inside the water tank 14 and the rear lower part inside the water tank 14 by adjusting the rotation position of the rotating piece 50a. The amount of jet water injected into the can be made different.

そのため、洗濯機１０は、例えば、実行する行程の内容に応じて、噴射口１８Ａ，１８Ｂからの噴射水量を異ならせるように構成してもよい。即ち、例えば、ドラム２０を所定の通常洗い用の回転速度、例えば５０〜６０ｒｐｍで回転させて行う通常の洗い行程では、回転するドラム２０内の洗濯物が当該ドラム２０の後方下部に偏る傾向がある。そのため、通常の洗い行程では、循環水を水槽１４内部の後方下部に噴射する噴射口用の循環路への流入量が多くなるように回動片部５０ａの回動位置を調整し、水槽１４内部の後方下部への噴射水量を多くするとよい。 Therefore, the washing machine 10 may be configured so that the amount of water injected from the injection ports 18A and 18B is different depending on, for example, the content of the process to be executed. That is, for example, in a normal washing process in which the drum 20 is rotated at a predetermined rotation speed for normal washing, for example, 50 to 60 rpm, the laundry in the rotating drum 20 tends to be biased toward the lower rear part of the drum 20. is there. Therefore, in the normal washing process, the rotation position of the rotating piece portion 50a is adjusted so that the amount of inflow into the circulation path for the injection port for injecting the circulating water into the lower rear part inside the water tank 14 is increased, and the water tank 14 is used. It is advisable to increase the amount of water jetted to the lower rear part of the interior.

また、例えば、ドラム２０を所定の遠心洗い用の回転速度、例えば１００ｒｐｍで回転させて行う遠心洗い行程では、回転するドラム２０内の洗濯物が遠心作用を受けて当該ドラム２０の内壁面の広範囲にわたって張り付く傾向がある。そのため、遠心洗い行程では、循環水を水槽１４内部の後方下部に噴射する噴射口用の循環路への流入量と循環水を水槽１４内部の前方下部に噴射する噴射口用の循環路への流入量とが均等になるように回動片部５０ａの回動位置を調整し、水槽１４内部の後方下部および前方下部に均等に水が噴射されるようにするとよい。 Further, for example, in the centrifugal washing process in which the drum 20 is rotated at a predetermined rotational speed for centrifugal washing, for example, 100 rpm, the laundry in the rotating drum 20 is subjected to the centrifugal action to cause a wide range of the inner wall surface of the drum 20. Tends to stick over. Therefore, in the centrifugal washing process, the amount of inflow into the circulation path for the injection port for injecting the circulating water to the rear lower part inside the water tank 14 and the circulation water for the injection port for injecting the circulating water to the front lower part inside the water tank 14 It is preferable to adjust the rotation position of the rotating piece portion 50a so that the inflow amount is uniform so that the water is evenly sprayed to the lower rear portion and the lower front portion inside the water tank 14.

（第４実施形態）
図９に例示するように、本実施形態の洗濯機１０は、第２実施形態に例示した洗濯機１０において、さらに水量調整部６０を備える。水量調整部６０は、注水カバー１９Ｂの仕切り壁部１９Ｂｂの基端部つまり循環水流入部１４ｃに接続する端部に設けられている。水量調整部６０は、回動片部６０ａが回動軸６０ｂを中心に、矢印Ｂ１，Ｂ２方向に回動可能に設けられた構成となっている。水量調整部６０は、例えばモータなどにより構成される図示しない駆動部により回動片部６０ａを回動させる構成としてもよいし、例えば洗濯機１０の使用者や製造者が手動により回動片部６０ａを回動させる構成としてもよい。 (Fourth Embodiment)
As illustrated in FIG. 9, the washing machine 10 of the present embodiment further includes a water amount adjusting unit 60 in the washing machine 10 illustrated in the second embodiment. The water amount adjusting portion 60 is provided at a base end portion of the partition wall portion 19Bb of the water injection cover 19B, that is, an end portion connected to the circulating water inflow portion 14c. The water amount adjusting portion 60 has a configuration in which a rotating piece portion 60a is provided so as to be rotatable in the directions of arrows B1 and B2 around a rotating shaft 60b. The water amount adjusting unit 60 may be configured to rotate the rotating piece 60a by a drive unit (not shown) composed of, for example, a motor, or the rotating piece unit may be manually rotated by, for example, a user or a manufacturer of the washing machine 10. It may be configured to rotate 60a.

回動片部６０ａを、最上流噴射口用循環路１４１ａ側である矢印Ｂ１側に回動させることにより、最上流噴射口用循環路１４１ａへの循環水Ｗの流入量を減らし、最下流噴射口用循環路１４１ｂへの循環水Ｗの流入量を増やすことができる。一方、回動片部６０ａを、最下流噴射口用循環路１４１ｂ側である矢印Ｂ２側に回動させることにより、最下流噴射口用循環路１４１ｂへの循環水Ｗの流入量を減らし、最上流噴射口用循環路１４１ａへの循環水Ｗの流入量を増やすことができる。即ち、水量調整部６０は、回動片部６０ａの回動位置を調整することにより、最上流噴射口用循環路１４１ａへの循環水Ｗの流入量および最下流噴射口用循環路１４１ｂへの循環水Ｗの流入量を調整可能に構成されている。 By rotating the rotating piece portion 60a toward the arrow B1 side, which is the circulation path 141a side for the most upstream injection port, the inflow amount of the circulating water W into the circulation path 141a for the most upstream injection port is reduced, and the most downstream injection is performed. The amount of circulating water W flowing into the oral circulation path 141b can be increased. On the other hand, by rotating the rotating piece portion 60a toward the arrow B2 side, which is the circulation path 141b side for the most downstream injection port, the inflow amount of the circulating water W into the circulation path 141b for the most downstream injection port is reduced, and the maximum amount is reduced. The inflow amount of the circulating water W into the circulation path 141a for the upstream injection port can be increased. That is, by adjusting the rotation position of the rotating piece portion 60a, the water amount adjusting unit 60 adjusts the inflow amount of the circulating water W into the circulation path 141a for the most upstream injection port and the circulation path 141b for the most downstream injection port. The inflow amount of the circulating water W can be adjusted.
