Description

本発明は、洗濯槽内へ注水する注水器を備えた洗濯機に関する。   The present invention relates to a washing machine provided with a water injector for pouring water into a washing tub.

洗濯機には、給水経路の途中部に設けられた洗剤や柔軟仕上げ剤等の処理剤投入装置を備え、前記処理剤投入装置に収容された処理剤を水で溶かしながら洗濯槽内に供給するようにしたものがある(例えば特許文献１)。   The washing machine includes a processing agent charging device such as a detergent or a softening finish provided in the middle of the water supply path, and supplies the processing agent contained in the processing agent charging device into the washing tub while dissolving with water. There is something like this (for example, Patent Document 1).

上記処理剤投入装置は、複数の処理剤収容室と前記収容室への給水経路を切り換える給水弁（ダブル給水弁）を有しており、洗濯行程に応じた処理剤収容室を水が通過するようにしている。このため、処理剤投入装置の構成が複雑になると共に当該処理剤投入装置の構成に合わせた専用の配水管、給水弁が必要となり、コストアップは避けられない。
特開２００２−３５５４９４号公報 The treatment agent charging device has a plurality of treatment agent storage chambers and a water supply valve (double water supply valve) that switches a water supply path to the storage chamber, and water passes through the treatment agent storage chamber according to the washing process. I am doing so. For this reason, the configuration of the processing agent charging apparatus becomes complicated, and a dedicated water distribution pipe and a water supply valve that match the configuration of the processing agent charging apparatus are necessary, and an increase in cost is inevitable.
JP 2002-355494 A

これに対して、回転槽の内周面に処理剤投入部を設け、洗濯槽へ供給される水を利用して投入部内の処理剤を洗濯槽に供給するようにした洗濯機がある。ところが、洗濯槽へ水を供給するための給水口は、通常、洗濯物投入口の後壁部分に設けられており、水道等の給水源からの水は、後方から給水口に向かって流れてくるように構成されている。このため、給水口から吐出される水を、回転槽の内周面付近に向けることは困難であった。   On the other hand, there is a washing machine in which a processing agent charging section is provided on the inner peripheral surface of the rotating tub and the processing agent in the charging section is supplied to the washing tub using water supplied to the washing tub. However, the water supply port for supplying water to the washing tub is usually provided in the rear wall portion of the laundry input port, and the water from the water supply source such as tap water flows from the rear toward the water supply port. It is comprised so that it may come. For this reason, it was difficult to direct the water discharged from a water supply port to the inner peripheral surface vicinity of a rotating tank.

本発明は上記した事情に鑑みてなされたものであり、その目的は、簡単な構成で給水手段からの水を洗濯槽の内周面付近に落下させることができる洗濯機を提供することである。   The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a washing machine capable of dropping water from the water supply means to the vicinity of the inner peripheral surface of the washing tub with a simple configuration. .

本発明は、外箱と、前記外箱内に収容された洗濯槽と、前記外箱の上に配置され中央に洗濯物投入口を有するトップカバーと、前記トップカバーに設けられ前記洗濯物投入口の内周面に装着口を有する装着部と、前記装着口を通して前記装着部に装着される注水器とを備え、前記注水器は、給水手段と、前記給水手段から供給される水の給水口を前面部に有する注水ケースと、前記給水口部を覆うように前記注水ケースの前面に取付けられた注水カバーとから構成されていると共に前記注水ケースの前面部と前記注水カバーとの間には、前記給水口からの水を前記洗濯槽に導く主注水路と、前記主注水路の下端部に設けられ前記洗濯物投入口内に位置する注水口と、前記主注水路の左右部に設けられた補助注水路とが形成され、前記主注水路、前記補助注水路は下端部で合流するように構成されていることを特徴とする。   The present invention includes an outer box, a washing tub accommodated in the outer box, a top cover disposed on the outer box and having a laundry inlet in the center, and the laundry input provided on the top cover. A mounting portion having a mounting port on an inner peripheral surface of the mouth; and a water injector attached to the mounting unit through the mounting port, the water injector supplying water and supplying water supplied from the water supplying unit A water injection case having a mouth on the front surface portion, and a water injection cover attached to the front surface of the water injection case so as to cover the water supply port portion, and between the front surface portion of the water injection case and the water injection cover Is provided at the left and right sides of the main water channel, the main water channel that guides water from the water inlet to the washing tub, the water inlet that is provided at the lower end of the main water channel and is located in the laundry inlet. The auxiliary irrigation channel formed and the main irrigation channel The auxiliary water injection passage is characterized by being configured to merge at the lower end.

本発明によれば、給水手段から供給された水は、出口部から主注水路に放出され、注水カバーに衝突することにより下方に向かって流れた後、注水口から洗濯槽内に落下する。この場合、注水口は洗濯物投入口の内周面付近に位置するため、注水口からの水は洗濯槽内の周辺部に落下する。また、出口部から放出される水の勢いが強く主注水路を越えて補助注水路に至った場合でも、その水は、下端部で主注水路に合流する。従って、上記注水器によれば、簡単な構成で、給水手段からの水を下方に方向転換させた後、洗濯槽の内周面付近に落下させることができる。   According to the present invention, the water supplied from the water supply means is discharged from the outlet portion to the main water injection channel, flows downward by colliding with the water injection cover, and then falls into the washing tub from the water injection port. In this case, since the water injection port is located in the vicinity of the inner peripheral surface of the laundry input port, the water from the water injection port falls to the peripheral part in the laundry tub. Moreover, even when the momentum of the water discharged from the outlet portion is strong and reaches the auxiliary water channel through the main water channel, the water merges with the main water channel at the lower end. Therefore, according to the water injector, with a simple configuration, the water from the water supply means can be turned downward and then dropped to the vicinity of the inner peripheral surface of the washing tub.

次に、本実施例の作用、効果を、上記注水器６から回転槽１３内に注水する動作及び処理剤投入部４８の洗剤が回転槽１３内に投入される動作を中心に説明する。まず、洗濯を行うにあたって、洗濯物投入口４から回転槽１３内に洗濯物を投入する。また、処理剤投入部４８の投入凹部４９に洗剤や漂白剤等を収容すると共に投入ケースに柔軟仕上げ剤を投入する。この状態で、洗濯運転が開始されると、給水弁２１が開放されて給水経路２４を後方から前方に向かって水が流れ、給水口２５から主注水路４１に水が放出される。このとき、給水口２５を給水経路２４の下部に沿う円弧状に構成したため、給水口２５から上方に向かって放出されることは殆どない。また、水の勢いが強く給水口２５から上方に向かって水が放出された場合でも、給水口２５の上方部及び左右側方部に位置する内枠部３３に衝突して下方に向かう。   Next, the operation and effect of the present embodiment will be described focusing on the operation of pouring water from the water injector 6 into the rotary tank 13 and the operation of supplying the detergent in the processing agent charging unit 48 into the rotary tank 13. First, when washing is performed, the laundry is put into the rotating tub 13 from the laundry loading port 4. In addition, a detergent, a bleaching agent, and the like are accommodated in the charging recess 49 of the processing agent charging unit 48 and a soft finish is charged in the charging case. When the washing operation is started in this state, the water supply valve 21 is opened, water flows through the water supply path 24 from the rear to the front, and water is discharged from the water supply port 25 to the main water supply channel 41. At this time, since the water supply port 25 is formed in an arc shape along the lower portion of the water supply path 24, the water supply port 25 is hardly discharged upward. Further, even when the water has a strong momentum and water is discharged upward from the water supply port 25, it collides with the inner frame portion 33 located at the upper part and the left and right side parts of the water supply port 25 and moves downward.

給水口２５から前方に放出された水は、注水カバー２０に当たった後、下方に向かう。そして、給水口２５の下部に設けられた多数のピン３４によって水の勢いが弱められた後、樋部３８に受けられる。樋部３８に受けられた水は、樋部３８の下辺の中央の窪んでいる部分から樋部３１に落ち、主注水口４２から放出される。   The water discharged forward from the water supply port 25 hits the water injection cover 20 and then moves downward. And after the momentum of water is weakened by many pins 34 provided in the lower part of the water supply opening | mouth 25, it is received by the collar part 38. FIG. The water received by the collar part 38 falls to the collar part 31 from a depressed part at the center of the lower side of the collar part 38 and is discharged from the main water inlet 42.

また、給水口２５から放出される水の勢いが強い場合は、主注水路４１内の水は、樋部３１，３８を越えて第１の補助注水路４３に至る。この場合、第１の補助注水路４３の外側に防水リブ２７，３７が設けられているため、第１の補助注水路４３に至った水が外側に漏れ出ることが防止される。第１の補助注水路４３に至った水は、当該補助注水路４３を下方に流れ、主注水口４２から放出される。   Further, when the momentum of the water discharged from the water supply port 25 is strong, the water in the main water injection channel 41 reaches the first auxiliary water injection channel 43 beyond the flanges 31 and 38. In this case, since the waterproof ribs 27 and 37 are provided on the outside of the first auxiliary water injection channel 43, the water reaching the first auxiliary water injection channel 43 is prevented from leaking outside. The water that has reached the first auxiliary water channel 43 flows downward through the auxiliary water channel 43 and is discharged from the main water inlet 42.

また、水が防水リブ２７，３７から外側に漏れ出た場合でも、その水は第２の補助注水路４４に入り込み下方に流れた後、水路３０を通って主注水口４２から落下する。
尚、水道の水圧が低く、水の勢いが弱い場合でも、給水口２５から主注水路４１に放出された水は、樋部３１，３８によって中央に集められた後、主注水口４２から放出される。 Even when water leaks outside from the waterproof ribs 27 and 37, the water enters the second auxiliary water injection channel 44 and flows downward, and then falls from the main water injection port 42 through the water channel 30.
Even when the water pressure of the water supply is low and the momentum of the water is weak, the water discharged from the water supply port 25 to the main water supply channel 41 is collected in the center by the flanges 31 and 38 and then discharged from the main water injection port 42. Is done.

主注水口４２から放出された水は、前記主注水口４２が洗濯物投入口４の内周面に位置しているため、回転槽１３内の周辺部分に落下し、処理剤投入部４８の投入凹部４９に入り込む。そして、投入凹部４９内の洗剤等と共に出口部５１から水路５０に至る。このとき、勢いが弱められた状態で主注水口４２から水が落下するように構成したため、投入凹部４９内の洗剤等が主注水口４２からの水で吹き飛ばされたり、オーバーフローしたりすることを防止できる。   Since the main water inlet 42 is located on the inner peripheral surface of the laundry input port 4, the water discharged from the main water inlet 42 falls to the peripheral portion in the rotating tub 13, and the It enters the insertion recess 49. And it reaches the water channel 50 from the outlet 51 together with the detergent and the like in the charging recess 49. At this time, since the water is configured to fall from the main water inlet 42 in a state where the momentum is weakened, the detergent or the like in the injection recess 49 is blown away by the water from the main water inlet 42 or overflows. Can be prevented.

また、水路５０に至った水及び洗剤等は、排水口５２から回転槽１３と水槽７との間に入り込み、孔１３ａを通じて回転槽１３内に流入する。
このように本実施例では、給水口２５を給水経路２４の先端の下半部の一部を開口させることにより構成した。このため、給水口２５から放出される水が上方に向かうことを防止できる。また、注水ケース１９の前面部に注水カバー２０を取付けることにより注水器６を構成した。そして、注水ケース１９の前面部に設けた給水口２５から放出される水を注水カバー２０に衝突させることにより、水の流れる方向を下方に転換させた。従って、簡単な構成で、給水口２５から前方に放出される水を下方に方向転換することができる。 Moreover, the water, detergent, etc. which reached the water channel 50 enter between the rotation tank 13 and the water tank 7 from the drain port 52, and flow into the rotation tank 13 through the hole 13a.
As described above, in this embodiment, the water supply port 25 is configured by opening a part of the lower half of the tip of the water supply path 24. For this reason, it can prevent that the water discharge | released from the water supply port 25 heads upwards. In addition, the water injector 6 was configured by attaching a water injection cover 20 to the front surface of the water injection case 19. And the water flow direction was changed below by making the water discharge | released from the water supply port 25 provided in the front part of the water injection case 19 collide with the water injection cover 20. FIG. Accordingly, the water discharged forward from the water supply port 25 can be redirected downward with a simple configuration.

また、給水口２５の上方及び側方に防水リブ２７，３７を設けた。そして、注水ケース１９に注水カバー２０を組み合わせたときに、注水ケース１９側の防水リブ２７と注水カバー２０側の防水リブ３７とが交互に位置するように構成した。このようなラビリンス構造を採用したことによりシール部材を設けなくても、高い防水性能を得ることができる。   Further, waterproof ribs 27 and 37 are provided above and to the side of the water supply port 25. And when the water injection cover 20 was combined with the water injection case 19, the waterproof rib 27 by the side of the water injection case 19 and the waterproof rib 37 by the side of the water injection cover 20 were comprised alternately. By adopting such a labyrinth structure, high waterproof performance can be obtained without providing a seal member.

また、注水ケース１９の防水リブ２７の根元部分に傾斜面２７ａを設けて、防水リブ２７の根元部分に防水リブ３７が隙間なく当接するように構成した。このため、防水リブ２７，３７の防水性能を一層高めることができ、給水口２５から主注水路４１に放出された水の勢いが強く、樋部３８を超えて補助注水路４３に至った場合でも、その水が防水リブ２７，３７を越えることを極力阻止することができる。   In addition, an inclined surface 27 a is provided at the base portion of the waterproof rib 27 of the water injection case 19 so that the waterproof rib 37 abuts against the base portion of the waterproof rib 27 without a gap. For this reason, the waterproof performance of the waterproof ribs 27 and 37 can be further improved, and the momentum of the water discharged from the water supply port 25 to the main water injection channel 41 is strong and reaches the auxiliary water injection channel 43 beyond the flange 38. However, it is possible to prevent the water from exceeding the waterproof ribs 27 and 37 as much as possible.

防水リブ２７，３７の下部の連結リブ２８や折曲部２９ａを外側から内側に向かって下方に傾斜させた。従って、補助注水路４３，４４に至った水は、連結リブ２８や折曲部２９ａによって主注水口４２に向かう。このため、主注水路４１からの水と補助注水路４３，４４からの水を容易に合流させることができる。   The connecting ribs 28 and the bent portions 29a below the waterproof ribs 27 and 37 are inclined downward from the outside toward the inside. Therefore, the water that has reached the auxiliary water injection channels 43 and 44 is directed to the main water injection port 42 by the connecting rib 28 and the bent portion 29a. For this reason, the water from the main water channel 41 and the water from the auxiliary water channels 43 and 44 can be easily merged.

更に、防水リブ２７，３７の外側には外枠部２６及び係止リブ３６が位置し、外枠部２６の下部に水路３０を設けた。従って、補助注水路４３，４４に至った水が万一、防水リブ２７，３７から漏れ出た場合でも、その水を、前記水路３０を通って主注水口４２に向かわせることができる。
第１の防水リブ２７の間に第２の防水リブ３７を嵌め込ませることにより隔壁を構成した。このようなラビリンス構造を採用したことにより、防水のためのシール部材を省略することができる。 Further, the outer frame portion 26 and the locking rib 36 are positioned outside the waterproof ribs 27 and 37, and the water channel 30 is provided at the lower portion of the outer frame portion 26. Therefore, even if the water that has reached the auxiliary water injection channels 43 and 44 leaks from the waterproof ribs 27 and 37, the water can be directed to the main water injection port 42 through the water channel 30.
A partition wall was formed by fitting the second waterproof rib 37 between the first waterproof ribs 27. By adopting such a labyrinth structure, a sealing member for waterproofing can be omitted.

また、本実施例に係る注水器６は、トップカバー３の装着口１８ａを通して装着部１８に取付けられるように構成した。従って、異なる構成の注水器であっても前記装着口１８ａを通して装着部１８に装着可能な形状であれば、或いは、装着口１８ａを通して装着部１８に装着可能な部分を備えていれば、同じ形状のトップカバーを利用することができる。つまり、注水器の構成が異なる複数タイプの洗濯機に対してトップカバーを共通化することができ、製造コストの削減を図ることができる。   In addition, the water injector 6 according to the present embodiment is configured to be attached to the mounting portion 18 through the mounting port 18 a of the top cover 3. Therefore, even if the water injector has a different configuration, the shape is the same as long as it has a shape that can be attached to the attachment portion 18 through the attachment opening 18a, or a portion that can be attached to the attachment portion 18 through the attachment opening 18a. The top cover can be used. That is, the top cover can be shared by a plurality of types of washing machines having different configurations of the water injector, and the manufacturing cost can be reduced.

尚、本発明は上記した実施例に限定されるものではなく、例えば次のような変形が可能である。
第１の防水リブの根元部に設けた傾斜面に代えて、第２の放水リブの根元部に傾斜面を設けても良い。 The present invention is not limited to the above-described embodiments, and for example, the following modifications are possible.
Instead of the inclined surface provided at the root portion of the first waterproof rib, an inclined surface may be provided at the root portion of the second water discharge rib.
