Description

本発明は、洗濯機に関する。   The present invention relates to a washing machine.

従来、全自動洗濯機では、洗濯の際に洗濯物から出る糸屑や埃を捕集するための構造の一つとして、図１０に示すリント捕集構造が採られている。かかるフィルタ捕集構造が採られた洗濯機が、たとえば、特許文献１に記載されている。   Conventionally, in a fully automatic washing machine, a lint collecting structure shown in FIG. 10 is adopted as one of the structures for collecting lint and dust coming out of the laundry during washing. For example, Patent Document 1 describes a washing machine in which such a filter collecting structure is adopted.

図１０（ａ）は、リントフィルタ捕集構造を示す、洗濯脱水槽５００の要部断面図である。洗濯脱水槽５００の側面部には、水路形成部材５１０により環流水路５２０が形成される。水路形成部材５１０には、後方に窪むフィルタ装着部５１１が形成され、フィルタ装着部５１１にフィルタユニット５３０が着脱自在に設けられる。フィルタ装着部５１１には、下面５１１ａに上方に突出する第１支軸５１２が形成され、上面５１１ｂに第１軸孔５１３が形成され、後面５１１ｃに流出口５１４が形成される。フィルタユニット５３０の下部に設けられた第２軸孔５３１が第１支軸５１２に嵌め込まれ、フィルタユニット５３０の上部に設けられた第２支軸５３２が第１軸孔５１３に嵌め込まれる。これにより、フィルタユニット５３０は、第１支軸５１２と第２支軸５３２とを回転軸として、左右方向に所定の角度だけ回転可能となる。環流水路５２０はパルセータ５４０の側方に接続される。   FIG. 10 (a) is a cross-sectional view of an essential part of the washing and dewatering tank 500 showing a lint filter collecting structure. A recirculating water passage 520 is formed by the water passage forming member 510 on the side surface portion of the washing and dewatering tank 500. The water channel forming member 510 is provided with a filter mounting portion 511 which is recessed rearward, and the filter unit 530 is detachably provided to the filter mounting portion 511. In the filter mounting portion 511, a first support shaft 512 projecting upward is formed on the lower surface 511a, a first axial hole 513 is formed on the upper surface 511b, and an outlet 514 is formed on the rear surface 511c. The second shaft hole 531 provided in the lower part of the filter unit 530 is fitted into the first support shaft 512, and the second support shaft 532 provided in the upper part of the filter unit 530 is fitted into the first shaft hole 513. Thus, the filter unit 530 can be rotated by a predetermined angle in the left-right direction with the first support shaft 512 and the second support shaft 532 as rotation axes. The reflux channel 520 is connected to the side of the pulsator 540.

パルセータ５４０が回転すると、矢印Ｆ１に示すように、パルセータ５４０の揚水羽根５４１によって外周方向に押し出された水が、環流水路５２０内に導かれ、流出口５１４から流出し、フィルタユニット５３０を通じて洗濯脱水槽５００内に戻される。この際、水に含まれる糸屑等がフィルタユニット５３０に捕集される。   When the pulsator 540 rotates, the water pushed outward by the pumping vanes 541 of the pulsator 540 is guided into the circulating water channel 520, flows out from the outlet 514, and is washed out through the filter unit 530, as shown by arrow F1. It is returned into the water tank 500. At this time, lint and the like contained in water are collected by the filter unit 530.

また、パルセータ５４０の回転より発生した水流に押されてフィルタユニット５３０が回転し、矢印Ｆ２に示すように、洗濯脱水槽５００の内周壁に沿って流れる水が、後面の取込口５３３からフィルタユニット５３０内に流入し、フィルタユニット５３０内を通過する。この際、水とともに流入した糸屑等がリントフィルタユニット５３０に捕集される。   Further, the filter unit 530 is rotated by the water flow generated by the rotation of the pulsator 540, and the water flowing along the inner peripheral wall of the washing and dewatering tank 500 is filtered from the intake port 533 on the rear surface as shown by arrow F2. It flows into the unit 530 and passes through the filter unit 530. At this time, lint and the like that flowed in with the water are collected by the lint filter unit 530.

特開２０００−３３４１９８号公報Unexamined-Japanese-Patent No. 2000-334198

水路形成部材５１０は、樹脂材料により形成され得る。この場合、水路形成部材５１０は、金型を用いて成形により製造される。   The water channel formation member 510 may be formed of a resin material. In this case, the water channel forming member 510 is manufactured by molding using a mold.

図１０（ｂ）は、水路構成部材５１０を成形する金型Ｍの要部を示す図である。たとえば、水路形成部材５１０の成形に、表側の第１金型Ｍ１と裏側の第２金型Ｍ２で構成され、水路形成部材５１０の前後方向に分割される金型Ｍが用いられ得る。この場合、第１支軸５１２の片側が第２金型Ｍ２で形成されるため、フィルタ装着部５１１の後面５１１ｃには、第１支軸５１２の背後となる位置に第２金型Ｍ２が通る開口部５１５が形成されることとなる。なお、金型Ｍに、第１支軸５１２の突出方向にスライドする第３金型を追加し、この第３金型によって第１支軸５１２を形成することも可能である。しかしながら、この場合、開口部５１５は形成されないが、後面５１１ｃにスライド跡が形成され、外観品位を損ねたり、糸屑等の引っかかりが発生したりする虞がある。   FIG. 10 (b) is a view showing the main part of a mold M for forming the water channel component 510. For example, for molding the water channel forming member 510, a metal mold M configured by the first mold M1 on the front side and the second metal mold M2 on the back side and divided in the front-rear direction of the water channel forming member 510 may be used. In this case, since one side of the first support shaft 512 is formed by the second mold M2, the second mold M2 passes through the rear surface 511c of the filter mounting portion 511 at a position behind the first support shaft 512. The opening 515 is to be formed. In addition, it is also possible to add the 3rd metal mold | die which slides to the protrusion direction of the 1st spindle 512 to the metal mold | die M, and to form the 1st spindle 512 by this 3rd metal mold | die. However, in this case, although the opening 515 is not formed, a slide mark is formed on the rear surface 511c, which may deteriorate the appearance quality or cause hooking of thread waste or the like.

水路形成部材５１０に形成された開口部５１５は、環流水路５２０内に連通する。このため、図１０（ａ）の矢印Ｆ３に示すように、環流水路５２０を流出口５１４に向かって流れる水の一部が、開口部５１５から流出する。流出した水は、フィルタユニット５３０を通らずに洗濯脱水槽５００内へ戻る。こうなると、フィルタユニット５３０による糸屑等の捕集効率が低下する虞がある。   An opening 515 formed in the water channel forming member 510 communicates with the circulating water channel 520. For this reason, as shown by arrow F 3 in FIG. 10A, a part of the water flowing toward the outflow port 514 flows out of the opening 515. The drained water returns to the washing and dewatering tank 500 without passing through the filter unit 530. If this happens, the collection efficiency of the lint etc. by the filter unit 530 may be reduced.

そこで、本発明は、糸屑等の捕集効率を向上させることができる洗濯機を提供することを目的とする。   Then, an object of this invention is to provide the washing machine which can improve the collection efficiency of lint etc.

本発明の主たる態様に係る洗濯機は、洗濯物を収容する洗濯脱水槽と、前記洗濯脱水槽の底部に回転自在に配置されるパルセータと、前記洗濯脱水槽の側面部に設けられ、前記パルセータの回転により送られてきた水が流れる環流水路と、前記洗濯脱水槽の内周壁との間で前記環流水路を形成する樹脂製の水路形成部材と、前記水路形成部材に形成されるフィルタ装着部と、前記フィルタ装着部に回転可能に装着され、前記環流水路から前記洗濯脱水槽内に戻る水と前記パルセータの回転で発生する水流により前記内周壁に沿って流れる水とを取り込んで通過させ、通過した水に含まれる糸屑等を捕集するフィルタユニットと、を備える。ここで、前記フィルタ装着部は、前記フィルタユニットの回転軸となる支軸と、当該支軸の背後に形成され前記環流水路内に連通する開口部とを含む。さらに、前記水路形成部材における前記環流水路に臨む面には、前記内周壁側へ向けて、前記開口部からの水の流出を抑制する壁部が形成される。   A washing machine according to a main aspect of the present invention comprises a washing and dewatering tank for containing laundry, a pulsator rotatably disposed at the bottom of the washing and dewatering tank, and a pulsator provided on a side surface of the washing and dewatering tank And a water passage forming member made of resin forming the circulation water passage between the circulation water passage through which the water sent by the rotation of the water flows and the inner peripheral wall of the washing and dewatering tank, and a filter mounting portion formed on the water passage forming member And water rotatably returned from the reflux water channel to the inside of the washing and dewatering tank and water flowing along the inner circumferential wall by the water flow generated by the rotation of the pulsator. And d) a filter unit for collecting thread waste and the like contained in the water passed through. Here, the filter mounting portion includes a support shaft serving as a rotation shaft of the filter unit, and an opening formed behind the support shaft and in communication with the circulating water channel. Furthermore, on the surface of the water channel formation member facing the reflux water channel, a wall is formed toward the inner peripheral wall side to suppress the flow of water from the opening.

上記の構成によれば、環流水路内を流れる水をフィルタユニット内に良好に導くことができるので、フィルタユニットによる糸屑等の捕集効率を向上させることが期待できる。   According to the above configuration, since the water flowing in the circulating water channel can be well led to the inside of the filter unit, it is expected that the collection efficiency of the lint etc. by the filter unit can be improved.

本態様に係る洗濯機において、前記壁部は、少なくとも前記開口部の下および左右の三方を囲むよう構成され得る。   In the washing machine according to this aspect, the wall may be configured to surround at least three sides below and at the right and left of the opening.

上記の構成によれば、壁部の下側の壁に当たって一旦分かれた水が側方から開口部に流入することを抑制でき、開口部からの水の流出をより一層抑制することができる。   According to said structure, it can suppress that the water which divided once hitting the lower wall of a wall part flows in into an opening from a side, and can control outflow of water from an opening still more.

上記の構成とされた場合、さらに、前記壁部と前記内周壁との間に隙間が形成され得る。   When it is set as said structure, a clearance gap may be further formed between the said wall part and the said inner peripheral wall.

このような構成とされると、開口部の少なくとも三方を囲った壁部の内部に、脱水工程の際、洗濯物から排出された水が侵入しても、侵入した水を隙間から環流水路内へ流し出すことができる。よって、壁部の内部に水が残ったままとなるのを防止できる。   With such a configuration, even if water discharged from the laundry intrudes into the inside of the wall portion surrounding at least three sides of the opening during the dewatering process, the intruded water can be introduced into the circulating water channel from the gap. You can pour it out. Therefore, it can prevent that water remains in the inside of a wall part.

本態様に係る洗濯機において、前記壁部は、前記開口部の左右方向における両端部よりも中央部が前記環流水路の上流側に張り出す形状を有する張出部を含む構成とされ得る。   In the washing machine according to this aspect, the wall portion may be configured to include an overhang portion having a shape in which a central portion protrudes to the upstream side of the reflux water channel from both end portions in the left-right direction of the opening.

上記の構成によれば、環流水路内を流れる水は、張出部に当たることで円滑に左右に分かれる。これにより、環流水路内の水の流速の低下を抑制できるので、糸屑等を水の流れに載せて良好にフィルタユニットまで運ぶことができる。   According to the above configuration, the water flowing in the circulating water channel is smoothly divided into right and left by hitting the overhang. Since the fall of the flow velocity of the water in a reflux channel can be suppressed by this, thread waste etc. can be put on the flow of water, and can be carried well to a filter unit.

本発明によれば、糸屑等の捕集効率を向上させることができる洗濯機を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the washing machine which can improve the collection efficiency of thread waste etc. can be provided.

以下、本発明の洗濯機の一実施形態である全自動洗濯機について、図面を参照して説明する。   Hereinafter, a fully automatic washing machine which is one embodiment of a washing machine of the present invention will be described with reference to the drawings.

図１は、全自動洗濯機１の構成を示す側面断面図である。   FIG. 1 is a side sectional view showing the configuration of a fully automatic washing machine 1.

全自動洗濯機１は、外観を構成する筐体１０を備える。筐体１０は、上下の面が開放された方形筒状の胴体部１１と、胴体部１１の上面を覆う上面板１２と、胴体部１１を支持する脚台１３とを含む。上面板１２には、洗濯物の投入口１４が形成される。投入口１４は、開閉自在な上蓋１５により覆われる。   The fully automatic washing machine 1 is provided with a housing 10 constituting an appearance. The housing 10 includes a rectangular cylindrical body portion 11 whose upper and lower surfaces are open, an upper surface plate 12 covering the upper surface of the body portion 11, and a footrest 13 for supporting the body portion 11. The top plate 12 is formed with a laundry inlet 14. The inlet 14 is covered by an openable upper lid 15.

筐体１０内には、外槽２０が、図示しない４本の吊棒により弾性的に吊り下げ支持される。外槽２０内には、洗濯脱水槽２１が配される。外槽２０および洗濯脱水槽２１は、前方にやや傾く。洗濯脱水槽２１は、鉛直方向に対して前方にやや傾いた回転軸Ｒを中心として回転する。筐体１０は、外槽２０の上部が前方へ張り出す分だけ前方へ張り出す張出部１０ａを有する。   In the housing 10, the outer tub 20 is elastically suspended and supported by four suspension rods (not shown). In the outer tank 20, a washing and dewatering tank 21 is disposed. The outer tub 20 and the washing and dewatering tub 21 are slightly inclined forward. The washing and dewatering tank 21 rotates about a rotation axis R slightly inclined forward with respect to the vertical direction. The housing 10 has a protruding portion 10 a protruding forward by an amount corresponding to the upper portion of the outer tub 20 protruding forward.

洗濯脱水槽２１の内周壁２１ａには、多数の脱水孔２１ｂが形成される。また、洗濯脱水槽２１の底面には、複数の通水孔２１ｃが形成される。さらに、洗濯脱水槽２１の上部には、バランスリング２２が設けられる。   A large number of dewatering holes 21 b are formed in the inner peripheral wall 21 a of the washing and dewatering tank 21. Further, on the bottom surface of the washing and dewatering tank 21, a plurality of water flow holes 21c are formed. Furthermore, a balance ring 22 is provided at the top of the washing and dewatering tank 21.

洗濯脱水槽２１の底部には、パルセータ２３が配される。パルセータ２３の表面には、表面中央から放射状に延びる複数の羽根２３ａが形成される。また、パルセータ２３の裏面には、裏面中央から放射状に延びる複数の揚水羽根２３ｂが形成される。これら揚水羽根２３ｂは、パルセータ２３の裏面と洗濯脱水槽２１の底面との間に形成されるポンプ室２４に配される。   A pulsator 23 is disposed at the bottom of the washing and dewatering tank 21. On the surface of the pulsator 23, a plurality of blades 23a extending radially from the center of the surface are formed. Further, on the back surface of the pulsator 23, a plurality of water pumping vanes 23b extending radially from the back surface center are formed. These pumping blades 23 b are disposed in a pump chamber 24 formed between the back surface of the pulsator 23 and the bottom surface of the washing and dewatering tank 21.

洗濯脱水槽２１の内周壁２１ａに沿って上下方向に延びる環流水路２５が、水路形成部材２６と内周壁２１ａとによって形成される。環流水路２５の下端部は、ポンプ室２４に繋がる。環流水路２５、即ち、環流水路２５を構成する水路形成部材２６に、フィルタユニット２７が取り外し可能に装着される。フィルタユニット２７は、洗濯の際に洗濯物から出る糸屑や埃を捕集する。   A circulating water channel 25 extending in the vertical direction along the inner peripheral wall 21 a of the washing and dewatering tank 21 is formed by the water channel forming member 26 and the inner peripheral wall 21 a. The lower end of the circulating water channel 25 is connected to the pump chamber 24. The filter unit 27 is removably attached to the reflux channel 25, that is, the channel forming member 26 constituting the reflux channel 25. The filter unit 27 collects lint and dust coming out of the laundry during washing.

外槽２０の外底部には、洗濯脱水槽２１およびパルセータ２３を駆動するトルクを発生させる駆動ユニット３０が配される。駆動ユニット３０は、駆動モータ３１と、伝達機構部３２とを含む。伝達機構部３２は、クラッチ機構を有し、当該クラッチ機構による切替操作により、洗い工程およびすすぎ工程では、駆動モータ３１のトルクをパルセータ２３のみに伝達してパルセータ２３のみを回転させ、脱水工程では、駆動モータ３１のトルクをパルセータ２３および洗濯脱水槽２１に伝達してパルセータ２３および洗濯脱水槽２１を一体的に回転させる。また、伝達機構部３２は、減速機構を有する。洗い工程およびすすぎ工程では、駆動モータ３１の回転数が減速機構の減速比に従って低くされた回転数でパルセータ２３が回転する。   At an outer bottom portion of the outer tank 20, a drive unit 30 for generating a torque for driving the washing and dewatering tank 21 and the pulsator 23 is disposed. The drive unit 30 includes a drive motor 31 and a transmission mechanism portion 32. The transmission mechanism section 32 has a clutch mechanism, and in the washing process and the rinsing process, the torque of the drive motor 31 is transmitted only to the pulsator 23 to rotate only the pulsator 23 by the switching operation by the clutch mechanism. The torque of the drive motor 31 is transmitted to the pulsator 23 and the washing and dewatering tank 21 to rotate the pulsator 23 and the washing and dewatering tank 21 integrally. Moreover, the transmission mechanism part 32 has a reduction mechanism. In the washing step and the rinsing step, the pulsator 23 is rotated at a rotational speed at which the rotational speed of the drive motor 31 is reduced in accordance with the speed reduction ratio of the speed reduction mechanism.

外槽２０の外底部には、排水口部２０ａが形成される。排水口部２０ａには、排水バルブ４０が設けられる。排水バルブ４０は、排水ホース４１に接続される。排水バルブ４０が開放されると、洗濯脱水槽２１および外槽２０に溜められた水が排水ホース４１を通じて機外へ排出される。   A drainage port 20 a is formed at the outer bottom of the outer tank 20. A drainage valve 40 is provided at the drainage port 20a. The drain valve 40 is connected to the drain hose 41. When the drain valve 40 is opened, the water stored in the washing and dewatering tank 21 and the outer tank 20 is drained to the outside of the machine through the drain hose 41.

上面板１２の後部には、水道水を洗濯脱水槽２１内に供給するための給水ユニット５０が配される。給水ユニット５０には給水バルブ５１が接続され、給水バルブ５１が水道栓に接続される。給水ユニット５０には、洗濯運転が行われる際に洗剤が投入される。給水バルブ５１が開放されると、給水ユニット５０内に水道水が導入される。導入された水道水は、給水ユニット５０内で洗剤と混合された後に給水ユニット５０から流出し、洗濯脱水槽２１内に供給される。   At the rear of the top plate 12, a water supply unit 50 for supplying tap water into the washing and dewatering tank 21 is disposed. A water supply valve 51 is connected to the water supply unit 50, and the water supply valve 51 is connected to a water tap. The detergent is introduced to the water supply unit 50 when the washing operation is performed. When the water supply valve 51 is opened, tap water is introduced into the water supply unit 50. The introduced tap water flows out of the water supply unit 50 after being mixed with the detergent in the water supply unit 50, and is supplied into the washing and dewatering tank 21.

全自動洗濯機１は、各種運転コースの洗濯運転を行う。洗濯運転は、洗い工程、中間脱水工程、すすぎ工程および最終脱水工程を含む。   The fully automatic washing machine 1 performs the washing operation of various operation courses. The washing operation comprises a washing step, an intermediate dewatering step, a rinsing step and a final dewatering step.

洗い工程およびすすぎ工程では、洗濯脱水槽２１内に水が溜められた状態で、パルセータ２３が右方向および左方向に回転する。パルセータ２３の回転により洗濯脱水槽２１内に水流が発生する。洗い工程では、発生した水流と水に含まれる洗剤とにより洗濯物が洗われる。すすぎ工程では、発生した水流により洗濯物がすすがれる。   In the washing step and the rinsing step, the pulsator 23 rotates rightward and leftward in a state where water is stored in the washing and dewatering tank 21. The rotation of the pulsator 23 generates a water flow in the washing and dewatering tank 21. In the washing step, the laundry is washed with the generated water stream and the detergent contained in the water. In the rinsing step, the generated water stream rinses the laundry.

中間脱水工程および最終脱水工程では、洗濯脱水槽２１およびパルセータ２３が一体となって高速回転する。洗濯脱水槽２１に発生する遠心力の作用により、洗濯物が脱水される。   In the intermediate dewatering process and the final dewatering process, the washing and dewatering tank 21 and the pulsator 23 rotate together at high speed. The laundry is dewatered by the action of the centrifugal force generated in the washing and dewatering tank 21.

The lint filter 110 is formed of a mesh bag body. The filter case 120 is formed in a hollow longitudinally long rectangular parallelepiped shape, and the rear surface is opened as the intake port 121. An attachment opening 122 is formed on the front surface of the filter case 120, and the lint filter 110 is attached to the attachment opening 122.

フィルタケース１２０の上端部には、下方に撓むことが可能な弾性片１２３が形成され、この弾性片１２３の上面に、上方に突出する上部支軸１２４が形成される。また、弾性片１２３の前端部に操作片１２５が形成される。ユーザは、この操作片１２５を指で押し下げることで弾性片１２３を下方に撓ませることができる。さらに、フィルタケース１２０の下端部には、下部軸孔１２６が形成される。   An elastic piece 123 which can be bent downward is formed at the upper end portion of the filter case 120, and an upper support shaft 124 which protrudes upward is formed on the upper surface of the elastic piece 123. In addition, the operation piece 125 is formed at the front end of the elastic piece 123. The user can bend the elastic piece 123 downward by depressing the operation piece 125 with a finger. Furthermore, a lower shaft hole 126 is formed at the lower end portion of the filter case 120.

水路形成部材２６は、樹脂材料により形成され、上下方向に延びるとともに前方にやや膨らむ。水路形成部材２６は、その表面が洗濯脱水槽２１の内部に臨み、その裏面が環流水路２５の内部に臨む。水路形成部材２６の表面には、フィルタユニット２７のフィルタケース１２０に対応する形状に窪んだフィルタ装着部２０１が形成される。   The water channel forming member 26 is formed of a resin material, extends in the vertical direction, and slightly bulges forward. The surface of the water channel forming member 26 faces the inside of the washing and dewatering tank 21, and the back surface thereof faces the inside of the circulating water channel 25. A filter mounting portion 201 is formed on the surface of the water channel forming member 26 in a shape corresponding to the filter case 120 of the filter unit 27.

フィルタ装着部２０１には、その底部２０１ａに、上方に突出する下部支軸２０２が形成され、その上部２０１ｂに上部軸孔２０３が形成される。下部支軸２０２は、本発明の支軸に相当する。   In the filter mounting portion 201, a lower support shaft 202 projecting upward is formed at a bottom portion 201a thereof, and an upper shaft hole 203 is formed at an upper portion 201b thereof. The lower spindle 202 corresponds to the spindle of the present invention.

フィルタ装着部２０１の後面２０１ｃには、中央部とそのやや下方に、複数の流出口２０４が形成される。また、フィルタ装着部２０１の後面２０１ｃには、上部に凹部２０５が形成される。凹部２０５には、フィルタユニット２７がフィルタ装着部２０１に装着されたときにフィルタユニット２７の弾性片１２３の後部が収容される。   A plurality of outlets 204 are formed in the central portion and slightly below the rear surface 201 c of the filter mounting portion 201. In addition, a recess 205 is formed on the upper surface of the rear surface 201 c of the filter mounting portion 201. When the filter unit 27 is attached to the filter attachment portion 201, the recess 205 accommodates the rear portion of the elastic piece 123 of the filter unit 27.

さらに、フィルタ装着部２０１の後面２０１ｃには、下部支軸２０２の背後の位置に、下部支軸２０２よりもやや大きな方形状の開口部２０６が形成される。水路形成部材２６は、金型を用いて成形により製造される。開口部２０６は、図１０（ｂ）で説明したように、成形製造の際、下部支軸２０２を形成する金型を通すために形成される。開口部２０６は、環流水路２５内に連通する。   Furthermore, in the rear surface 201 c of the filter mounting portion 201, a rectangular opening 206 slightly larger than the lower support shaft 202 is formed at a position behind the lower support shaft 202. The water channel forming member 26 is manufactured by molding using a mold. The opening 206 is formed to pass through a mold forming the lower spindle 202 during molding and manufacturing, as described in FIG. 10 (b). The opening 206 communicates with the circulating water channel 25.

水路形成部材２６の表面には、フィルタ装着部２０１の左右両側に、それぞれ、フィルタ装着部２０１と同様に窪むとともに左右方向に延びる複数の右流路２０７および左流路２０８が形成される。   On the surface of the water channel forming member 26, a plurality of right channels 207 and left channels 208 which are depressed in the same manner as the filter mounting portion 201 and extend in the left-right direction are formed respectively on the left and right sides of the filter mounting portion 201.

水路形成部材２６の裏面には、後方に向けて２重構造の水路区画リブ２０９が形成される。水路区画リブ２０９の内側領域が環流水路２５となる。さらに、水路形成部材２６の裏面には、開口部２０６の周囲に、後方、即ち、洗濯脱水槽２１の内周壁２１ａ側に向けて遮水壁部２１０が形成される。遮水壁部２１０は、本発明の壁部に相当する。遮水壁部２１０は、開口部２０６の四方が囲まれるように、方形の筒状に形成され、下壁２１１、上壁２１２、左壁２１３および右壁２１４を有する。図２に示すように、水路形成部材２６が洗濯脱水槽２１の内周壁２１ａに取り付けられた状態において、遮水壁部２１０と内周壁２１ａとの間に所定の隙間Ｓが形成される。   On the back surface of the water channel formation member 26, a water channel partition rib 209 having a double structure is formed toward the rear. The inner region of the water channel partition rib 209 is the circulating water channel 25. Furthermore, on the back surface of the water channel formation member 26, a water blocking wall portion 210 is formed around the opening 206 toward the rear, that is, toward the inner peripheral wall 21 a side of the washing and dewatering tank 21. The water blocking wall portion 210 corresponds to the wall portion of the present invention. The water blocking wall portion 210 is formed in a rectangular tubular shape so that the four sides of the opening portion 206 are surrounded, and has a lower wall 211, an upper wall 212, a left wall 213, and a right wall 214. As shown in FIG. 2, when the water channel forming member 26 is attached to the inner circumferential wall 21 a of the washing and dewatering tank 21, a predetermined gap S is formed between the water blocking wall portion 210 and the inner circumferential wall 21 a.

フィルタユニット２７は、水路形成部材２６のフィルタ装着部２０１に装着される。水路形成部材２６の装着の際、ユーザは、まず、フィルタユニット２７の下部軸孔１２６をフィルタ装着部２０１の下部支軸２０２に嵌め込む。次に、ユーザは、フィルタユニット２７の操作片１２５を押し下げ、上部支軸１２４がフィルタ装着部２０１の上部軸孔２０３より低くなるように弾性片１２３を下方に撓ませながら、フィルタユニット２７の上部を後方に移動させる。そして、ユーザは、上部支軸１２４が上部軸孔２０３の位置に達すると、弾性片１２３の撓みを開放して、上部支軸１２４を上部軸孔２０３に嵌め込む。フィルタユニット２７は、上部支軸１２４および下部支軸２０２を回転軸として、水路形成部材２６の正面から見て右方向または左方向に所定角度だけ回転可能となる状態で、水路形成部材２６に固定される。   The filter unit 27 is mounted on the filter mounting portion 201 of the water channel forming member 26. When mounting the water channel forming member 26, the user first fits the lower shaft hole 126 of the filter unit 27 into the lower spindle 202 of the filter mounting portion 201. Next, the user pushes down the operation piece 125 of the filter unit 27 and bends the elastic piece 123 downward so that the upper support shaft 124 is lower than the upper shaft hole 203 of the filter mounting portion 201. Move backwards. Then, when the upper support shaft 124 reaches the position of the upper shaft hole 203, the user releases the bending of the elastic piece 123 and inserts the upper support shaft 124 into the upper shaft hole 203. The filter unit 27 is fixed to the water channel forming member 26 in a state where it can be rotated by a predetermined angle rightward or leftward when viewed from the front of the water channel forming member 26 with the upper spindle 124 and the lower spindle 202 as rotation axes. Be done.

次に、図２および図３を参照して、フィルタユニット２７による糸屑等の捕集動作について説明する。   Next, with reference to FIG. 2 and FIG. 3, the collection operation of the lint etc. by the filter unit 27 will be described.

洗い工程またはすすぎ工程において、パルセータ２３が回転すると、揚水羽根２３ｂによるポンプ作用によって、洗濯脱水槽２１と外槽２０との間の水が通水孔２１ｃを通じてポンプ室２４内に吸い込まれ、外周方向に押し出される。矢印Ｆ１に示すように、押し出された水は、環流水路２５内を上昇して流出口２０４から流出し、フィルタユニット２７のリントフィルタ１１０を通じて洗濯脱水槽２１内に戻される。この際、水に含まれる糸屑等がリントフィルタ１１０に捕集される。   In the washing step or the rinsing step, when the pulsator 23 is rotated, the water between the washing and dewatering tank 21 and the outer tank 20 is sucked into the pump chamber 24 through the water flow hole 21c by the pump action of the pumping vanes 23b. Pushed out. As shown by the arrow F 1, the extruded water ascends in the reflux water channel 25, flows out from the outlet 204, and is returned into the washing and dewatering tank 21 through the lint filter 110 of the filter unit 27. At this time, lint and the like contained in water are collected by the lint filter 110.

また、図３（ａ）および（ｂ）に示すように、パルセータ２３の回転により右回りまたは左回りの水流が発生すると、フィルタユニット２７が右方向または左方向に傾く。これにより、矢印Ｆ２に示すように、洗濯脱水槽２１の内周壁２１ａに沿って流れる水が、後面の取込口１２１からフィルタユニット２７内に流入し、リントフィルタ１１０を通過する。この際、水に含まれる糸屑等がリントフィルタ１１０に捕集される。   Further, as shown in FIGS. 3A and 3B, when the clockwise or counterclockwise water flow is generated by the rotation of the pulsator 23, the filter unit 27 is inclined to the right or left. As a result, as shown by arrow F 2, the water flowing along the inner circumferential wall 21 a of the washing and dewatering tank 21 flows into the filter unit 27 from the inlet 121 of the rear surface and passes through the lint filter 110. At this time, lint and the like contained in water are collected by the lint filter 110.

図７は、環流水路２５内を流出口２０４へと向かう水の流れを示す図である。流出口２０４の上流に位置する開口部２０６は遮水壁部２１０で囲まれており、環流水路２５内を上昇する水は、遮水壁部２１０の下壁２１１に当たって左右に分かれ、遮水壁部２１０の左右両側を流れて流出口２０４へと至る。これにより、環流水路２５内を流れる水の一部が開口部２０６から流出してしまうのを抑制できる。   FIG. 7 is a diagram showing the flow of water heading in the reflux water channel 25 to the outlet 204. The opening 206 located upstream of the outlet 204 is surrounded by the water blocking wall 210, and the water rising in the circulating water channel 25 strikes the lower wall 211 of the water blocking wall 210 and is divided into left and right It flows on the left and right sides of the part 210 and reaches the outlet 204. As a result, it is possible to suppress that part of the water flowing in the circulating water channel 25 flows out of the opening 206.

なお、脱水工程の際に、洗濯物から排出された水が開口部２０６を通じて遮水壁部２１０の内部に侵入する場合が生じ得る。この場合、侵入した水は、遮水壁部２１０と内周壁２１ａとの隙間Ｓから環流水路２５内へ流れる。よって、遮水壁部２１０の内部に水が残ったままとなりにくい。   In addition, the case where the water discharged | emitted from the laundry intrudes into the inside of the impermeable wall part 210 through the opening part 206 may arise at the time of a spin-drying | dehydration process. In this case, the entering water flows into the circulating water channel 25 from the gap S between the water blocking wall portion 210 and the inner circumferential wall 21a. Therefore, it is hard for water to remain in the inside of the water blocking wall portion 210.

＜本実施の形態の効果＞
以上、本実施の形態によれば、水路形成部材２６の裏面に設けた遮水壁部２１０により環流水路２５内を流れる水の一部が開口部２０６から流出してしまうのを抑制できる。よって、環流水路２５内を流れる水をフィルタユニット２７内に良好に導くことができるので、フィルタユニット２７による糸屑等の捕集効率を向上させることが期待できる。 <Effect of this embodiment>
As described above, according to the present embodiment, the impermeable wall portion 210 provided on the back surface of the water channel formation member 26 can suppress part of the water flowing in the circulating water channel 25 from flowing out from the opening 206. Therefore, the water flowing in the circulating water channel 25 can be well led to the inside of the filter unit 27, so that it is expected that the collection efficiency of the lint etc. by the filter unit 27 can be improved.

また、本実施の形態によれば、遮水壁部２１０は、開口部２０６の四方を囲む構成とされるので、下壁２１１で一旦分かれた水が側方から開口部２０６に流入することを抑制でき、開口部２０６からの水の流出をより一層抑制することができる。   Further, according to the present embodiment, since the water blocking wall portion 210 is configured to surround the four sides of the opening portion 206, water once divided by the lower wall 211 flows into the opening portion 206 from the side. Therefore, the outflow of water from the opening 206 can be further suppressed.

さらに、本実施の形態によれば、遮水壁部２１０と洗濯脱水槽２１の内周壁２１ａとの間に隙間Ｓが形成されるので、脱水工程の際に遮水壁部２１０の内部に侵入した水を、隙間Ｓから環流水路２５内へ流し出すことができ、遮水壁部２１０の内部に水が残ったままとなるのを防止できる。   Furthermore, according to the present embodiment, since the gap S is formed between the water blocking wall portion 210 and the inner circumferential wall 21 a of the washing and dewatering tank 21, the water penetrates into the water blocking wall portion 210 during the dewatering process. It is possible to flush out the drained water from the gap S into the reflux water channel 25 and prevent the water from remaining in the water blocking wall portion 210.

以上、本発明の実施の形態について説明したが、本発明は、上記実施の形態によって何ら制限されるものではなく、また、本発明の実施の形態も、上記以外に種々の変更が可能である。   As mentioned above, although embodiment of this invention was described, this invention is not restrict | limited at all by the said embodiment, Moreover, the embodiment of this invention can also be variously modified in addition to the above. .

＜変更例１＞
図８（ａ）は、変更例１に係る、遮水壁部２１０Ａの構成を示す、水路形成部材２６の要部の背面斜視図である。 <Modification 1>
Fig.8 (a) is a back perspective view of the principal part of the water channel formation member 26 which shows the structure of water blocking wall part 210A based on the example 1 of a change.

本変更例における遮水壁部２１０Ａは、開口部２０６の下縁において左右方向に延びる下壁２１１のみにより構成される。遮水壁部２１０Ａの幅は、開口部２０６の横幅よりも大きくされる。環流水路２５内を上昇する水は、遮水壁部２１０Ａに当たって左右に分かれ、開口部２０６の左右両外側を流れて流出口２０４へと至る。   The water blocking wall portion 210 </ b> A in the present modified example is configured of only the lower wall 211 extending in the left and right direction at the lower edge of the opening 206. The width of the water blocking wall portion 210A is larger than the width of the opening 206. Water rising in the circulating water channel 25 strikes the water blocking wall portion 210A and is divided into right and left, and flows on both left and right outer sides of the opening 206 to reach the outlet 204.

よって、本変更例によっても、環流水路２５内を流れる水の一部が開口部２０６から流出してしまうのを抑制でき、フィルタユニット２７による糸屑等の捕集効率を向上させることが期待できる。   Therefore, according to this modification as well, it is possible to suppress that part of the water flowing in the circulating water channel 25 flows out from the opening 206, and it can be expected to improve the collection efficiency of the lint etc. by the filter unit 27. .

＜変更例２＞
図８（ｂ）は、変更例１に係る、遮水壁部２１０Ｂの構成を示す、水路形成部材２６の要部の背面斜視図である。 <Modification 2>
FIG. 8B is a rear perspective view of the main part of the water channel formation member 26 showing the configuration of the water blocking wall portion 210B according to the first modification.

本変更例における遮水壁部２１０Ｂは、下壁２１１の下に、左右の両端部よりも中央部が環流水路２５の上流側に張り出すほぼＶ字形状を有する張出部２１５を含む。
環流水路２５内を上昇する水は、張出部２１５に当たって左右に分かれ、遮水壁部２１０Ｂの左右両側を流れて流出口２０４へと至る。 The water blocking wall portion 210B in the present modified example includes, under the lower wall 211, an overhanging portion 215 having a substantially V shape in which a central portion projects to the upstream side of the circulating water channel 25 than both left and right ends.
Water rising in the circulating water channel 25 strikes the overhang portion 215 and is divided into right and left, and flows on both left and right sides of the water blocking wall portion 210B to reach the outlet 204.

よって、本変更例によっても、環流水路２５内を流れる水の一部が開口部２０６から流出してしまうのを抑制でき、フィルタユニット２７による糸屑等の捕集効率を向上させることが期待できる。   Therefore, according to this modification as well, it is possible to suppress that part of the water flowing in the circulating water channel 25 flows out from the opening 206, and it can be expected to improve the collection efficiency of the lint etc. by the filter unit 27. .

さらに、本変更例によれば、環流水路２５内を流れる水は、張出部２１５に当たることで円滑に左右に分かれる。これにより、環流水路２５内の水の流速の低下を抑制できるので、糸屑等を水の流れに載せて良好にフィルタユニット２７まで運ぶことができる。   Furthermore, according to this modification, the water flowing in the circulating water channel 25 is smoothly divided into right and left by hitting the overhanging portion 215. Since the fall of the flow velocity of the water in the reflux water channel 25 can be suppressed by this, thread waste etc. can be put on the flow of water, and can be carried to the filter unit 27 favorably.

＜その他の変更例＞
上記実施の形態の遮水壁部２１０、上記変更例１の遮水壁部２１０Ａおよび上記変更例２の遮水壁部２１０Ｂの他、開口部２０６からの水の流出を抑制する壁部として、たとえば、図９に示すように、種々の遮水壁部２１０Ｃ〜２１０Ｉが開口部２０６に関連して設けられ得る。 Other Modifications
In addition to the water blocking wall portion 210 of the above embodiment, the water blocking wall portion 210A of the first modification, and the water blocking wall portion 210B of the second modification, as a wall portion that suppresses the flow of water from the opening 206 For example, as shown in FIG. 9, various impermeable wall portions 210C-210I may be provided in connection with the opening 206.

Further, as shown in FIG. 9B, a water blocking wall portion 210D is provided which has a lower wall 211, a left wall 213 and a right wall 214, but the left and right walls 213, 214 do not extend to the upper end of the opening 206. May be As in the case of the water blocking wall portions 210C and 210D in FIGS. 9A and 9B, when at least the lower side and the three sides of the opening 206 are surrounded, the water once divided by the lower wall 211 opens from the side. Since it can suppress flowing in, the outflow of the water from the opening 206 can be further suppressed as compared with the water blocking wall portion 210A configured only by the lower wall 211 as in the first modification.

さらに、図９（ｃ）に示すように、下壁２１１がなく、左右の壁２１３、２１４からＶ状の張出部２１５が形成される遮水壁部２１０Ｅが設けられてもよい。さらに、図９（ｄ）および（ｅ）に示すように、Ｖ字状でなく、円弧またはＵ字状の張出部２１６を有する遮水壁部２１０Ｆ、２１０Ｇが設けられてもよい。さらに、図９（ｆ）に示すように、Ｖ字状の張出部２１５のみにより構成される遮水壁部２１０Ｈが設けられてもよい。さらに、図９（ｇ）に示すように、円弧またはＵ字状の張出部２１６のみにより構成される遮水壁部２１０Ｉが設けられてもよい。   Furthermore, as shown in FIG.9 (c), there may not be the lower wall 211 and the impermeable wall part 210E in which the V-shaped overhang part 215 is formed from the right and left walls 213 and 214 may be provided. Furthermore, as shown in FIGS. 9D and 9E, water blocking wall portions 210F and 210G may be provided which have overhangs 216 that are not V-shaped but arc or U-shaped. Furthermore, as shown in FIG. 9F, a water blocking wall portion 210H may be provided which is configured only by the V-shaped overhanging portion 215. Furthermore, as shown in FIG. 9 (g), a water blocking wall portion 210I configured only by the arc or U-shaped overhang portion 216 may be provided.

さらに、上記実施の形態では、水路形成部材２６は、バランスリング２２の位置まで上方に延びており、フィルタユニット２７よりも上方の部位は、水流により撹拌される洗濯物が擦れるバッフルとして機能する。しかしながら、上方の部位は、環流水路２５として機能していないため、なくされてもよい。   Further, in the above embodiment, the water channel forming member 26 extends upward to the position of the balance ring 22, and the portion above the filter unit 27 functions as a baffle against which the laundry stirred by the water flow is rubbed. However, the upper part may be eliminated because it does not function as the reflux channel 25.

さらに、上記実施の形態では、外槽２０と洗濯脱水槽２１とが前方に傾いているが、これらが傾いていなくてもよい。   Furthermore, in the above embodiment, the outer tub 20 and the washing and dewatering tub 21 are inclined forward, but they may not be inclined.

上記実施の形態の全自動洗濯機１は、乾燥機能を備えていないが、本発明は、乾燥機能を備えた全自動洗濯機に適用することもできる。   Although the fully automatic washing machine 1 of the above embodiment does not have a drying function, the present invention can also be applied to a fully automatic washing machine provided with a drying function.

この他、本発明の実施の形態は、特許請求の範囲に示された技術的思想の範囲内において、適宜、種々の変更が可能である。   Besides the above, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
