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 described herein relate generally to a water injection case for a washing machine and a washing machine.

近年、マイクロバブルやナノバブルと称される直径が数十nm〜数μmサイズの微細気泡が注目されてきており、多数の微細気泡を含んだ微細気泡水を洗濯機に用いることが考えられている。しかしながら従来構成では、微細気泡を発生させるために、大掛かりな装置を用いたり複雑な形状の部品を用いたりしていた。そして従来、これらの装置や部品は、洗濯機が本来備える構成とは別部品で構成されていた。そのため、例えば洗濯機の組立工程では、微細気泡を発生させるため装置や部品を取り付ける作業が新たに発生し、これにより洗濯機の組立等に手間がかかり作業性が低下していた。   In recent years, microbubbles having a diameter of several tens of nanometers to several μm, called microbubbles and nanobubbles, have attracted attention, and it is considered to use microbubble water containing a large number of microbubbles in a washing machine. . However, in the conventional configuration, in order to generate fine bubbles, a large-scale device or a component having a complicated shape is used. Conventionally, these devices and parts have been configured as separate parts from the structure originally provided in the washing machine. For this reason, for example, in the assembly process of the washing machine, a new operation of attaching devices and parts to generate fine bubbles has occurred, which has taken time and labor to assemble the washing machine and reduced workability.

When a certain amount of water accumulates in the liquid detergent container 33, the water flows down from the liquid detergent outlet 331 to the outside of the liquid detergent container 33 due to the siphon structure of the liquid detergent outlet 331, and then from the water inlet 41. Water is poured into the water tank 13 and the rotating tank 14. At this time, if the liquid detergent is stored in the liquid detergent container 33, the liquid detergent is dissolved in the water flowing out from the liquid detergent outlet 331, and flows from the water inlet 41 into the water tank 13 and the rotating tank 14. Be dropped.

仕上げ剤流路出口47は、仕上げ剤収容部34に対応しており、仕上げ剤収容部34の上部に位置している。仕上げ剤用流路45を通った水は、仕上げ剤流路出口47から収容空間43内に流出し、仕上げ剤流路出口47の下方に位置する仕上げ剤収容部34内に注がれる。そして、仕上げ剤収容部34に一定量の水が溜まると、その水は、仕上げ剤流出部341のサイフォン構造によって仕上げ剤流出部341から仕上げ剤収容部34外に流れ落ち、その後、注水口41から水槽13及び回転槽14内へ注水される。このとき、仕上げ剤収容部34内に液状の仕上げ剤が収容されていれば、その仕上げ剤は、仕上げ剤流出部341から流れ出る水に溶かされて、注水口41から水槽13及び回転槽14内へ流し落とされる。   The finishing agent flow path outlet 47 corresponds to the finishing agent storage portion 34 and is located above the finishing agent storage portion 34. The water that has passed through the finishing agent passage 45 flows out from the finishing agent passage outlet 47 into the accommodation space 43 and is poured into the finishing agent storage portion 34 located below the finishing agent passage outlet 47. When a certain amount of water accumulates in the finishing agent storage portion 34, the water flows down from the finishing agent outflow portion 341 to the outside of the finishing agent storage portion 34 by the siphon structure of the finishing agent outflow portion 341, and then from the water injection port 41. Water is poured into the water tank 13 and the rotating tank 14. At this time, if a liquid finishing agent is stored in the finishing agent storage part 34, the finishing agent is dissolved in the water flowing out from the finishing agent outflow part 341, and is supplied from the water inlet 41 to the water tank 13 and the rotary tank 14. Washed away.

流路入口48、49は、それぞれ各流路44、45の入口部を構成するもので、各流路44、45についてそれぞれ1つずつ設けられている。すなわち、流路入口48は、洗剤用流路44に対応して洗剤用流路44の上流側端部に設けられており、洗剤用流路44の入口部を構成する。流路入口49は、仕上げ剤用流路45に対応して仕上げ剤用流路45の上流側端部に設けられており、仕上げ剤用流路45の入口部を構成する。この場合、洗剤用流路44に対応する流路入口48を洗剤用流路入口48と称し、仕上げ剤用流路45に対応する流路入口49を仕上げ剤用流路入口49と称する。   The flow path inlets 48 and 49 constitute the inlet portions of the flow paths 44 and 45, respectively, and one flow path 44 and 45 is provided. That is, the flow path inlet 48 is provided at the upstream end of the detergent flow path 44 corresponding to the detergent flow path 44 and constitutes the inlet of the detergent flow path 44. The channel inlet 49 is provided at the upstream end of the finishing agent channel 45 corresponding to the finishing agent channel 45 and constitutes the inlet of the finishing agent channel 45. In this case, the channel inlet 48 corresponding to the detergent channel 44 is referred to as a detergent channel inlet 48, and the channel inlet 49 corresponding to the finishing agent channel 45 is referred to as a finishing agent channel inlet 49.

流路入口48、49は、図3にも示すように、それぞれ接続部481、491及び微細気泡発生部50、50を有している。接続部481、491は、注水ケース本体40の外部から各流路44、45内へ連通するように円筒形状に形成されている。給水弁22、23の吐出側の先端部221、231は、接続部481、491に挿入可能となっている。これにより、給水弁22、23の吐出側の先端部221、231は、接続部481、491に着脱可能に接続される。   As shown in FIG. 3, the flow path inlets 48 and 49 have connection portions 481 and 491 and fine bubble generation portions 50 and 50, respectively. The connection portions 481 and 491 are formed in a cylindrical shape so as to communicate with the flow paths 44 and 45 from the outside of the water injection case body 40. Discharge-side tips 221 and 231 of the water supply valves 22 and 23 can be inserted into the connection portions 481 and 491. Thereby, the front end portions 221 and 231 on the discharge side of the water supply valves 22 and 23 are detachably connected to the connection portions 481 and 491.

この場合、給水弁22、23の吐出側の先端部221、231は、それぞれシール部材222、232を介して、接続部481、491と微細気泡発生部50の境界部分、つまり接続部481、491の底部に係止される。シール部材222、232は、例えばゴム等の弾性部材で構成されたOリングであり、吐出部221、231の先端部の外周面部分に設けられている。これにより、各吐出部221、231と接続部481、491とは、シール部材222、232によって水密状態で相互に接続されている。   In this case, the discharge-side tip portions 221 and 231 of the water supply valves 22 and 23 are connected to the boundary portions between the connection portions 481 and 491 and the fine bubble generating portion 50 via the seal members 222 and 232, that is, the connection portions 481 and 491, respectively. Is locked to the bottom. The seal members 222 and 232 are O-rings made of, for example, an elastic member such as rubber, and are provided on the outer peripheral surface portions of the distal end portions of the discharge portions 221 and 231. Thereby, each discharge part 221,231 and the connection part 481,491 are mutually connected in the watertight state by the sealing members 222,232.

微細気泡発生部50は、注水ケース本体40と一体に設けられおり、水の通過可能な面積を局所的に縮小することにより流路44、45から流出する水に微細気泡を含ませて微細気泡水を生成するためのものである。微細気泡発生部50は、流路44、45の始点から終点に至るいずれかの箇所、すなわち流路44、45の流路入口48、49から流路出口46、47に至るいずれかの箇所に設けられている。本実施形態の場合、微細気泡発生部50は、各流路44、45の流路入口48、49に設けられている。   The fine bubble generating unit 50 is provided integrally with the water injection case body 40, and by locally reducing the area through which water can pass, the fine bubbles are included in the water flowing out from the flow paths 44 and 45, thereby forming fine bubbles. It is for producing water. The fine bubble generating unit 50 is located at any point from the start point to the end point of the flow paths 44, 45, that is, at any position from the flow path inlets 48, 49 of the flow paths 44, 45 to the flow path outlets 46, 47. Is provided. In the case of this embodiment, the fine bubble generating unit 50 is provided at the channel inlets 48 and 49 of the channels 44 and 45.

なお、本実施形態において微細気泡水とは、微細気泡発生部50を通過することによって、微細気泡発生部50を通過する以前に比べてナノオーダーの微細気泡いわゆるウルトラファインバブルを多く含んだ水をいう。すなわち、本実施形態において、微細気泡水とは、何ら処理を行っていない通常の水道水や風呂水等に比べてナノオーダーの微細気泡を多く含んだ水をいう。本実施形態の洗濯機10は、回転槽14内の洗濯物を洗う洗濯運転や、回転槽14内の洗濯物をすすぐすすぎ運転、又は、水槽13及び回転槽14を洗浄する槽洗浄運転等を行う際に、微細気泡発生部50を通って生成された微細気泡水を利用する。   In addition, in this embodiment, the fine bubble water is water containing a large amount of nano-order fine bubbles, so-called ultra fine bubbles, by passing through the fine bubble generation unit 50 compared to before passing through the fine bubble generation unit 50. Say. That is, in the present embodiment, the fine bubble water refers to water containing more nano-order fine bubbles than ordinary tap water or bath water that is not subjected to any treatment. The washing machine 10 of the present embodiment performs a washing operation for washing the laundry in the rotating tub 14, a rinsing operation for rinsing the laundry in the rotating tub 14, or a tank washing operation for washing the water tub 13 and the rotating tub 14. When performing, the fine bubble water produced | generated through the fine bubble generation | occurrence | production part 50 is utilized.

ここで、一般に微細気泡は、その気泡の粒子径によって次のように分類されている。例えば、粒子径が数μmから50μm程度つまりマイクロオーダーの気泡は、マイクロバブル又はファインバブルと称されている。これに対し、粒子径が数百nm〜数十nm以下つまりナノオーダーの気泡は、ナノバブル又はウルトラファインバブルと称されている。   Here, the fine bubbles are generally classified as follows according to the particle diameter of the bubbles. For example, bubbles having a particle size of about several μm to 50 μm, that is, micro-order bubbles are called microbubbles or fine bubbles. On the other hand, bubbles having a particle size of several hundred nm to several tens of nm or less, that is, nano-order bubbles are called nanobubbles or ultrafine bubbles.

気泡の粒子径が数百nm〜数十nm以下になると、光の波長よりも小さくなるため視認することができなくなり、液体は透明になる。そして、ナノオーダーの微細気泡は、マイクロオーダー以上の気泡に比べて、総界面面積が大きいこと、浮上速度が遅いこと、内部圧力が大きいこと等の特性を有している。例えば、粒子径がマイクロオーダーの気泡は、その浮力によって液体中を急速に上昇し、液体表面で破裂して消滅するため、液体中の滞在時間が比較的短い。一方、粒子径がナノオーダーの微細気泡は、浮力が小さいため液体中での滞在時間が長い。   When the bubble particle diameter is several hundred nm to several tens of nm or less, it becomes smaller than the wavelength of light and cannot be visually recognized, and the liquid becomes transparent. The nano-order fine bubbles have characteristics such as a large total interface area, a low levitation speed, and a large internal pressure, as compared with bubbles of the micro-order or higher. For example, bubbles having a particle size of the micro order rapidly rise in the liquid due to the buoyancy, and rupture and disappear on the liquid surface. Therefore, the residence time in the liquid is relatively short. On the other hand, microbubbles having a particle size of nano-order have a long residence time in a liquid because of their small buoyancy.

粒子径がナノオーダーの微細気泡を含む微細気泡水は、界面活性剤等を含む洗剤を用いずに、洗濯運転や、水槽13及び回転槽14の洗浄運転を行った場合でも、水道水に比べてある程度の洗浄性能の向上が見込まれる。しかしながら、粒子径がナノオーダーの微細気泡いわゆるウルトラファインバブルを、界面活性剤が溶けた洗浄液中に混ぜることで、微細気泡を含まない通常の洗浄液で洗浄を行った場合に比べて更に効率良く洗浄性能を向上させることができる。   Fine bubble water containing fine bubbles with a nano-order particle diameter is compared with tap water even when washing operation or washing operation of the water tank 13 and the rotating tank 14 is performed without using a detergent containing a surfactant or the like. Some improvement in cleaning performance is expected. However, by mixing nano-sized fine bubbles, so-called ultra fine bubbles, in a cleaning solution in which a surfactant is dissolved, cleaning is performed more efficiently than when cleaning with a normal cleaning solution that does not contain fine bubbles. Performance can be improved.

本実施形態において、微細気泡発生部50の直径及び全長は、数mm〜数十mm程度、具体的には直径が最大約15mmで長さが約10mmに設定されている。微細気泡発生部50は、図3に示すように、絞り部51、ストレート部52、及び衝突部53を有している。絞り部51及びストレート部52は、微細気泡発生部50の長手方向へ向かって貫いた穴であり、微細気泡発生部50の流路を構成する。   In the present embodiment, the diameter and the total length of the fine bubble generating unit 50 are set to about several mm to several tens mm, specifically, the diameter is about 15 mm at the maximum and the length is about 10 mm. As shown in FIG. 3, the fine bubble generating unit 50 includes a throttle unit 51, a straight unit 52, and a collision unit 53. The throttle part 51 and the straight part 52 are holes penetrating in the longitudinal direction of the fine bubble generating part 50 and constitute a flow path of the fine bubble generating part 50.

絞り部51は、微細気泡発生部50の流入側つまり上流側に設けられている。絞り部51は、微細気泡発生部50の長手方向の上流側端部から途中部分にかけて流路の断面積つまり内径が連続的に徐々に減少するようないわゆる円錐形のテーパ管状に形成されている。ストレート部52は、絞り部51の下流側に設けられている。ストレート部52は、内径が変化しない、すなわち流路の断面積つまり液体の通過可能な面積が変化しない円筒形、いわゆるストレート管状に形成されている。   The throttle part 51 is provided on the inflow side, that is, the upstream side of the fine bubble generation part 50. The throttle part 51 is formed in a so-called conical tapered tube in which the cross-sectional area of the flow path, that is, the inner diameter gradually decreases gradually from the upstream end in the longitudinal direction of the fine bubble generating part 50 to the middle part. . The straight part 52 is provided on the downstream side of the throttle part 51. The straight part 52 is formed in a so-called straight tubular shape in which the inner diameter does not change, that is, the cross-sectional area of the flow path, that is, the area through which the liquid can pass does not change.

衝突部53は、ストレート部52の上流端から下流端に至る部分のうち任意の箇所に設けられている。本実施形態の場合、衝突部53は、ストレート部52の下流側の端部に設けられている。衝突部53は、微細気泡発生部50における水の通過可能な断面積を局所的に縮小することで、微細気泡発生部50を通過する液体中に微細気泡を発生させることができる。すなわち、衝突部53は、ストレート部52の断面積を局所的に縮小することで、ストレート部52を通過する液体中に微細気泡を発生させることができる。   The collision part 53 is provided at an arbitrary position in the part from the upstream end to the downstream end of the straight part 52. In the case of this embodiment, the collision part 53 is provided at the downstream end of the straight part 52. The collision part 53 can generate fine bubbles in the liquid passing through the fine bubble generating part 50 by locally reducing the cross-sectional area through which the water can pass in the fine bubble generating part 50. That is, the collision part 53 can generate fine bubbles in the liquid passing through the straight part 52 by locally reducing the cross-sectional area of the straight part 52.

本実施形態の場合、衝突部53は、図4に示すように、例えば先端が尖った4本の棒状の部分で構成され、ストレート部52の内周面からこのストレート部52の断面における中心方向へ向かって突出している。4本の衝突部53は、ストレート部52の断面の周方向に向かって相互に等間隔に離間した状態で配置されている。この場合、各衝突部53の下流側の面は、平坦面に形成されている。すなわち、各衝突部53の下流側の面は、流路44、45を構成する面と同一面に形成されている。   In the case of this embodiment, as shown in FIG. 4, the collision portion 53 is composed of, for example, four rod-like portions with sharp tips, and the central direction in the cross section of the straight portion 52 from the inner peripheral surface of the straight portion 52. Projecting toward. The four collision portions 53 are arranged in a state of being spaced apart at equal intervals toward the circumferential direction of the cross section of the straight portion 52. In this case, the downstream surface of each collision portion 53 is formed as a flat surface. That is, the downstream surface of each collision portion 53 is formed on the same surface as the surfaces constituting the flow paths 44 and 45.

各給水弁22、23が開放されて、微細気泡発生部50の上流側に水が流入すると、円錐テーパ形状に縮小するように形成された絞り部51において流路断面積が絞られることによって、流体力学のいわゆるベンチュリ効果により流速が高められる。そして、その高速流がストレート部52を通過する際に衝突部53に衝突することで圧力が急激に低下される。これにより、水中に溶存している空気を微細な気泡として多量に析出させることができ、各流路44、45に微細気泡水を供給する。   When each of the water supply valves 22 and 23 is opened and water flows into the upstream side of the fine bubble generating unit 50, the flow passage cross-sectional area is reduced in the throttle portion 51 formed so as to reduce to a conical taper shape. The flow velocity is increased by the so-called Venturi effect of hydrodynamics. And when the high-speed flow passes the straight part 52, it collides with the collision part 53, and a pressure falls rapidly. Thereby, a large amount of air dissolved in the water can be deposited as fine bubbles, and fine bubble water is supplied to each of the flow paths 44 and 45.

このように、微細気泡発生部50は、外部から気体の供給を能動的つまり積極的に得ることなく、微細気泡発生部50を通過する水に微細気泡を含ませて微細気泡水を生成することができる。そして、各微細気泡発生部50で生成された微細気泡水は、それぞれ流路44、45を通って、それぞれ洗濯剤収容部32、33、34に供給された後、洗濯剤収容部32、33、34に収容された洗濯剤と共に注水口41から水槽13及び回転槽14内へ注がれる。   In this way, the fine bubble generating unit 50 generates fine bubble water by including fine bubbles in the water passing through the fine bubble generating unit 50 without actively or positively obtaining gas supply from the outside. Can do. And the fine bubble water produced | generated in each fine bubble generation | occurrence | production part 50 is each supplied to the washing | cleaning agent accommodating part 32, 33, 34 through the flow paths 44 and 45, respectively, Then, the washing | cleaning agent accommodating part 32, 33 , 34 is poured into the water tank 13 and the rotating tank 14 from the water inlet 41 together with the washing agent accommodated in the water.

この場合、微細気泡発生部50は、通常の水圧つまり水道の圧力以外には、微細気泡を発生させるための専用のポンプ等の駆動源を必要としない。なお、例えば微細気泡発生部50は、絞り部51又はストレート部52の内部と外部とを連通する穴を有し、微細気泡発生部50内を流れる水に外部の空気を取り込むようにしても良い。これによれば、水中に溶存する空気の量を増大させることができ、その結果、析出される微細気泡の量も増大させることができる。   In this case, the fine bubble generating unit 50 does not require a drive source such as a dedicated pump for generating fine bubbles, other than normal water pressure, that is, water pressure. For example, the fine bubble generating unit 50 may have a hole that allows communication between the inside of the throttle unit 51 or the straight unit 52 and the outside, and may take external air into the water flowing in the fine bubble generating unit 50. . According to this, the amount of air dissolved in water can be increased, and as a result, the amount of fine bubbles deposited can also be increased.

また、図2に示すように、流路44、45は、それぞれ受け部441、451を有している。受け部441、451は、微細気泡発生部50から吐出された微細気泡水を受けてその微細気泡水を一時的に滞留させた後に下流側へ流す部分である。本実施形態の場合、受け部441、451は、各流路44、45の上流側の空間の一部であって、微細気泡発生部50の直後に設けられている。すなわち、受け部441、451を構成する周囲の壁面は、微細気泡発生部50における衝突部53の下流側の面を含んでいる。この場合、受け部441の容積は、微細気泡発生部50から吐出された微細気泡水が常時満たされる程度に小さい容積に設定されている。これにより、微細気泡発生部50から吐出された微細気泡水に含まれる微細気泡の量を増大させることができる。   In addition, as shown in FIG. 2, the flow paths 44 and 45 have receiving portions 441 and 451, respectively. The receiving parts 441 and 451 are parts that receive the fine bubble water discharged from the fine bubble generation part 50 and temporarily flow the microbubble water to the downstream side after it is retained. In the case of this embodiment, the receiving portions 441 and 451 are part of the space on the upstream side of the flow paths 44 and 45 and are provided immediately after the fine bubble generating portion 50. That is, the surrounding wall surfaces constituting the receiving portions 441 and 451 include the downstream surface of the collision portion 53 in the fine bubble generating portion 50. In this case, the volume of the receiving part 441 is set to a small volume such that the fine bubble water discharged from the fine bubble generation part 50 is always filled. Thereby, the quantity of the fine bubble contained in the fine bubble water discharged from the fine bubble generation part 50 can be increased.

この構成において、洗濯機10は、例えば洗濯物を洗う洗い工程や、複数回のすすぎ工程のうちの最後となる最終すすぎ工程以外のすすぎ工程時における注水、すなわち、仕上げ剤を用いない注水では、仕上げ剤用給水弁23を開かずに洗剤用給水弁22を開く。これにより、洗剤用流路44を通った微細気泡水が、洗濯剤収容部32、33を経て注水口41から水槽13及び回転槽14内に注水される。   In this configuration, the washing machine 10 is, for example, water injection in a rinsing process other than a final rinsing process that is the last of a plurality of rinsing processes, that is, water injection that does not use a finishing agent. The detergent supply valve 22 is opened without opening the finishing agent supply valve 23. Thereby, the fine bubble water that has passed through the detergent flow path 44 is poured into the water tank 13 and the rotating tank 14 from the water injection port 41 through the washing agent storage portions 32 and 33.

一方、洗濯機10は、例えば仕上げ剤を用いる最終すすぎ工程時における注水では、洗剤用給水弁22と共に仕上げ剤用給水弁23も開く。これにより、洗剤用流路44を通った微細気泡水が、洗濯剤収容部32、33を経て注水口41から水槽13及び回転槽14内に注水されると共に、仕上げ剤用流路45を通った微細気泡水が、仕上げ剤収容部34を経て注水口41から水槽13及び回転槽14内に注水される。   On the other hand, the washing machine 10 opens the water supply valve 23 for the finishing agent together with the water supply valve 22 for the detergent in the water injection in the final rinsing process using the finishing agent, for example. As a result, the fine bubble water that has passed through the detergent channel 44 is poured into the water tank 13 and the rotary tank 14 from the water inlet 41 through the laundry accommodating portions 32 and 33, and through the finish agent channel 45. The fine bubble water is injected into the water tank 13 and the rotating tank 14 from the water injection port 41 through the finishing agent storage portion 34.

以上説明した実施形態によれば、洗濯機10の注水ケース30は、洗濯剤を収容する洗濯剤収容部32、33、34と、注水ケース本体40と、流路44、45と、微細気泡発生部50、50と、を備える。注水ケース本体40は、洗濯剤収容部32、33、34を収容する収容空間43を内部に有している。流路44、45は、注水ケース本体40の内部にあって収容空間43の上流側に設けられている。流路44、45は、注水ケース本体40の外部から供給された水を通してその水を収容空間43内の洗濯剤収容部32、33、34へ流す。微細気泡発生部50は、注水ケース本体40と一体に設けられている。微細気泡発生部50は、水の通過可能な面積を局所的に縮小することにより流路44、45から流出する水に微細気泡を含ませて微細気泡水を生成することができる。   According to the embodiment described above, the water injection case 30 of the washing machine 10 includes the washing agent storage portions 32, 33, and 34, the water injection case body 40, the flow paths 44 and 45, and the generation of fine bubbles. Parts 50 and 50. The water injection case main body 40 has therein a storage space 43 for storing the washing agent storage portions 32, 33, 34. The flow paths 44 and 45 are provided inside the water injection case main body 40 and on the upstream side of the accommodation space 43. The flow paths 44 and 45 flow the water through the water supplied from the outside of the water injection case body 40 to the washing agent storage portions 32, 33 and 34 in the storage space 43. The fine bubble generating unit 50 is provided integrally with the water injection case body 40. The fine bubble generating unit 50 can generate fine bubble water by locally reducing the area through which water can pass so that the water flowing out from the flow paths 44 and 45 contains fine bubbles.

これによれば、微細気泡を発生させるために、大掛かりな装置や複雑な形状で細かい部品等を用いる必要がなく、従来と同様の注水ケース30を組み立てる工程を行うことで、微細気泡水を発生させる機能を得ることができる。そのため、注水ケース30や洗濯機10の組立工程において、微細気泡を発生させるため装置や部品を取り付けるための新たな作業を発生させずに、洗濯機10に微細気泡水を用いることができる。したがって、微細気泡を発生させる機能を備えた注水ケース30及び洗濯機10において、組立作業性を向上させることができる。   According to this, in order to generate fine bubbles, it is not necessary to use a large-scale device or a complicated part and fine parts, etc., and fine bubble water is generated by performing the same process of assembling the water injection case 30 as before. Function can be obtained. Therefore, in the assembling process of the water injection case 30 and the washing machine 10, the fine bubble water can be used for the washing machine 10 without generating a new operation for attaching devices and parts to generate fine bubbles. Therefore, in the water injection case 30 and the washing machine 10 having the function of generating fine bubbles, the assembly workability can be improved.

また、微細気泡発生部50は、流路44、45の入口部となる流路入口48、49に設けられている。すなわち、本実施形態によれば、微細気泡発生部50、50は、水圧が安定し易い箇所である、給水弁22、23から吐出された直後の流路入口48、49に設けられている。したがって、本実施形態によれば、微細気泡発生部50、50には、安定した水圧の水が供給されるため、微細気泡水を安定して生成することができる。   Further, the fine bubble generating unit 50 is provided at the flow channel inlets 48 and 49 which are the inlet portions of the flow channels 44 and 45. That is, according to the present embodiment, the fine bubble generating units 50 and 50 are provided at the flow path inlets 48 and 49 immediately after being discharged from the water supply valves 22 and 23, which are places where the water pressure is easily stabilized. Therefore, according to this embodiment, since the water of the stable water pressure is supplied to the fine bubble generation | occurrence | production parts 50 and 50, fine bubble water can be produced | generated stably.

また、注水ケース30は、受け部441、451を注水ケース本体40と一体に有している。受け部441、451は、微細気泡発生部50、50から吐出された微細気泡水を受けてその微細気泡水を一時的に滞留させた後に下流側へ流す機能を有する。これによれば、微細気泡発生部50、50から流路44、45内に供給する微細気泡水に含まれる微細気泡の数を増大させて、微細気泡水の洗浄効果等をより高いものとすることができる。   Further, the water injection case 30 has receiving portions 441 and 451 integrally with the water injection case main body 40. The receiving portions 441 and 451 have a function of receiving the fine bubble water discharged from the fine bubble generating portions 50 and 50, temporarily retaining the fine bubble water, and then flowing it downstream. According to this, the number of microbubbles contained in the microbubble water supplied from the microbubble generators 50 and 50 into the flow paths 44 and 45 is increased, and the cleaning effect of the microbubble water is enhanced. be able to.

次に、第2実施形態について図5を参照して説明する。本実施形態において、微細気泡発生部50、50は、流路入口48、49ではなく、流路44、45の出口部となる流路出口46、47に設けられている。この場合、洗剤用流路44に対応した微細気泡発生部50は、粉末洗剤用流路出口461と液体洗剤用流路出口462とのうち、少なくとも液体洗剤用流路出口462に設けられている。なお、微細気泡発生部50は、粉末洗剤用流路出口461に設けられていても良い。
(Second Embodiment)
Next, a second embodiment will be described with reference to FIG. In the present embodiment, the fine bubble generating units 50 and 50 are provided not at the flow channel inlets 48 and 49 but at the flow channel outlets 46 and 47 that are the outlets of the flow channels 44 and 45. In this case, the fine bubble generating unit 50 corresponding to the detergent channel 44 is provided at least at the liquid detergent channel outlet 462 among the powder detergent channel outlet 461 and the liquid detergent channel outlet 462. . In addition, the fine bubble generation | occurrence | production part 50 may be provided in the flow path outlet 461 for powder detergents.

また、注水ケース本体40は、上記第1実施形態の受け部441、451に換えて、受け部442、452を有している。受け部442、452は、第1実施形態の受け部441、451と同様に、各微細気泡発生部50、50から吐出された微細気泡水を受けてその微細気泡水を一時的に滞留させた後に下流側へ流す部分である。   Moreover, the water injection case main body 40 has receiving portions 442 and 452 instead of the receiving portions 441 and 451 of the first embodiment. The receiving portions 442 and 452 receive the fine bubble water discharged from the respective fine bubble generating portions 50 and 50 and temporarily retain the fine bubble water, similarly to the receiving portions 441 and 451 of the first embodiment. This is the part that flows downstream later.

本実施形態の場合、受け部442、452は、仕切り部42から下方に延び出て仕切り部42に一体に設けられた壁部443、453に囲まれて構成されている。流路44、45を通って各微細気泡発生部50、50から吐出された微細気泡水は、受け部442、452で受けられて一旦滞留した後、受け部442、452の出口444、454から液体の洗濯剤を収容する洗濯剤収容部33、34に注ぎ込まれる。そして、洗濯剤収容部33、34に注ぎ込まれた微細気泡水は、洗濯剤収容部33、34内に収容されている液体の洗濯剤とともに注水口41から水槽13及び回転槽14内へ注水される。   In the case of this embodiment, the receiving portions 442 and 452 are configured to be surrounded by wall portions 443 and 453 that extend downward from the partition portion 42 and are provided integrally with the partition portion 42. The microbubble water discharged from the microbubble generators 50 and 50 through the flow paths 44 and 45 is received by the receivers 442 and 452 and once retained, and then from the outlets 444 and 454 of the receivers 442 and 452. It is poured into the laundry storage units 33 and 34 for storing the liquid laundry. Then, the fine bubble water poured into the laundry storage units 33 and 34 is poured into the water tank 13 and the rotary tank 14 from the water injection port 41 together with the liquid laundry stored in the laundry storage units 33 and 34. The

以上説明した第2実施形態によれば、上記第1実施形態と同様の作用効果が得られる。ここで、各微細気泡発生部50、50から吐出された微細気泡水は、勢いが良いため、洗濯剤収容部33、34に各微細気泡発生部50、50から吐出された微細気泡水を直接注ぐと、その微細気泡水によって過剰な泡が生じてしまい、洗濯剤収容部33、34に収容されている洗濯剤を適切に水槽13内に流し落とすことが出来なくなる。   According to the second embodiment described above, the same operational effects as those of the first embodiment can be obtained. Here, since the fine bubble water discharged from each of the fine bubble generation units 50 and 50 has good momentum, the fine bubble water discharged from each of the fine bubble generation units 50 and 50 is directly applied to the washing agent storage units 33 and 34. When poured, excessive bubbles are generated by the fine bubble water, and the washing agent stored in the washing agent containing portions 33 and 34 cannot be appropriately poured into the water tank 13.

これに対し、本実施形態において、受け部442、452は、それぞれ収容空間43内にあって微細気泡発生器50の直後に設けられている。すなわち、本実施形態の受け部442、452は、それぞれ微細気泡発生器50と液体の洗濯剤を収容する洗濯剤収容部33、34との間に設けられている。これによれば、流路44、45を通って各微細気泡発生部50、50から吐出された微細気泡水は、受け部442、452で受けられて一旦滞留した後に洗濯剤収容部33、34に注ぎ込まれる。したがって、本実施形態によれば、各微細気泡発生部50、50から勢い良く吐出された微細気泡水が勢いの良いまま洗濯剤収容部33、34に直接注ぎ込まれることがない。そのため、洗濯剤収容部33、34内で過剰な泡が発生することを抑制でき、その結果、洗濯剤収容部33、34内の洗剤を適切に水槽13内に流し落とすことができる。   On the other hand, in the present embodiment, the receiving portions 442 and 452 are respectively provided in the accommodation space 43 and immediately after the fine bubble generator 50. That is, the receiving portions 442 and 452 of the present embodiment are provided between the fine bubble generator 50 and the washing agent storage portions 33 and 34 for storing the liquid washing agent, respectively. According to this, the fine bubble water discharged from each fine bubble generation part 50, 50 through the flow paths 44, 45 is received by the receiving parts 442, 452, and once retained, then the washing agent storage parts 33, 34. Poured into. Therefore, according to this embodiment, the fine bubble water discharged vigorously from each fine bubble generation part 50 and 50 is not poured directly into the washing | cleaning agent accommodating part 33 and 34 with sufficient vigor. Therefore, generation | occurrence | production of excess foam in the washing | cleaning agent accommodating parts 33 and 34 can be suppressed, As a result, the detergent in the washing | cleaning agent accommodating parts 33 and 34 can be poured into the water tank 13 appropriately.

更に本実施形態によれば、微細気泡発生部50、50は、流路44、45の出口部となる流路出口462、47に設けられている。本実施形態の場合、洗剤用流路44に対応した微細気泡発生部50は、粉末洗剤用流路出口461と液体洗剤用流路出口462とのうち、少なくとも液体洗剤用流路出口462に設けられている。   Furthermore, according to the present embodiment, the fine bubble generating units 50 and 50 are provided at the channel outlets 462 and 47 that are the outlets of the channels 44 and 45. In the present embodiment, the fine bubble generating unit 50 corresponding to the detergent flow path 44 is provided at least in the liquid detergent flow path outlet 462 among the powder detergent flow path outlet 461 and the liquid detergent flow path outlet 462. It has been.

これによれば、微細気泡発生部50を通過して生成された微細気泡水を、その生成後の比較的短い期間で洗濯剤収容部33、34内の洗剤と接触させて混ぜることができる。すなわち、微細気泡水中の微細気泡の数は、その発生直後から時間経過とともに減少するが、本実施形態によれば、微細気泡の数の減少を極力抑えた状態で、微細気泡と洗濯剤とを接触させて混ぜることができる。その結果、微細気泡による洗濯剤性能の向上効果を十分に引き出すことができる。   According to this, the fine bubble water produced | generated through the fine bubble generation | occurrence | production part 50 can be brought into contact with the detergent in the washing | cleaning agent accommodating parts 33 and 34 in the comparatively short period after the production | generation, and can be mixed. That is, the number of microbubbles in the microbubble water decreases with time from immediately after the occurrence, but according to the present embodiment, the microbubbles and the washing agent are reduced in a state where the decrease in the number of microbubbles is suppressed as much as possible. Can be mixed in contact. As a result, the effect of improving the washing agent performance due to the fine bubbles can be sufficiently extracted.

ここで、微細気泡発生部50は、水が通過する面積を局所的に縮小するものである。そのため、微細気泡発生部50を、全ての流路出口461、462、47に設けると、注水口41から吐出される水量が減少し、その結果、例えば洗濯運転時における注水時間が増大する可能性がある。   Here, the fine bubble generating unit 50 locally reduces the area through which water passes. Therefore, if the fine bubble generating units 50 are provided at all the channel outlets 461, 462, 47, the amount of water discharged from the water injection port 41 decreases, and as a result, for example, the water injection time during the washing operation may increase. There is.

この場合、液体の洗濯剤すなわち液体洗剤や柔軟仕上げ剤等は、液状であるため、微細気泡水に接触する前に通常の水道水によって水槽13及び回転槽14内に流し落とされてしまうと、微細気泡水と接触して混合する前に衣類に浸み込んでしまう。すると、液体の洗濯剤と微細気泡水とが接触し難くなり、微細気泡水の効果が得られ難い。したがって、液体の洗濯剤は、水槽13及び回転槽14に投入される前に、微細気泡水と混ぜ合わせることが望ましい。   In this case, since the liquid washing agent, that is, the liquid detergent, the soft finish, and the like are in a liquid state, if they are washed away into the water tank 13 and the rotating tank 14 by normal tap water before coming into contact with the fine bubble water, It will soak into clothing before coming into contact with the microbubble water and mixing. Then, it becomes difficult for the liquid detergent and the fine bubble water to come into contact with each other, and it is difficult to obtain the effect of the fine bubble water. Therefore, it is desirable that the liquid laundry is mixed with the fine bubble water before being put into the water tank 13 and the rotating tank 14.

一方、粉末洗剤は、単に水と接触しただけでは溶け難く、水槽13内に投入された後、回転槽14及びパルセータ15が回転されて撹拌されることによって、水槽13内の水に溶け込む。そのため、粉末洗剤は、単に水槽13内に投入されただけでは衣類にしみ込み難い。したがって、粉末洗剤を水槽13及び回転槽14内に投入した後に、その粉末洗剤と微細気泡水とを接触させても、十分に微細気泡水の効果を得ることができる。   On the other hand, the powder detergent is difficult to dissolve simply by contact with water, and after being put into the water tank 13, the rotating tank 14 and the pulsator 15 are rotated and stirred to dissolve in the water in the water tank 13. For this reason, the powder detergent is difficult to soak into clothing simply by being put into the water tank 13. Therefore, even if the powder detergent is put into the water tank 13 and the rotating tank 14 and then the powder detergent is brought into contact with the fine bubble water, the effect of the fine bubble water can be sufficiently obtained.

そこで、本実施形態において、微細気泡発生部50は、各流路出口461、462、47のうち、液体の洗濯剤を収容する洗濯剤収容部331、341に対応した流路出口462、47に設けられており、粉末洗剤を収容する洗濯剤収容部332に対応した流路出口461には設けられていない。これによれば、注水口41から吐出される水量すなわち水槽13への単位時間当たりの注水量の低下を抑制しつつ、各種の洗濯剤と微細気泡水とを適切な時期に接触させて微細気泡水の効果を効果的に引き出すことができる。   Therefore, in the present embodiment, the fine bubble generating unit 50 is connected to the flow path outlets 462 and 47 corresponding to the laundry storage parts 331 and 341 that store the liquid detergent among the flow path outlets 461, 462, and 47, respectively. It is provided, but is not provided at the flow path outlet 461 corresponding to the washing agent storage portion 332 that stores the powder detergent. According to this, while suppressing a decrease in the amount of water discharged from the water injection port 41, that is, the amount of water injected per unit time into the water tank 13, various types of washing agents and fine bubble water are brought into contact with each other at an appropriate time to form fine bubbles. The effect of water can be extracted effectively.
