Description

この発明は、洗浄機に関する。   The present invention relates to a washing machine.

特許文献１に記載の洗濯機は、洗濯槽の底部に回転可能に設けられたパルセータと、洗濯槽の内周面に設けられたバッフルとを含む。バッフルは、パルセータの回転軸に対して所定角度で傾いた姿勢で、洗濯槽の内周側に膨出して設けられる。洗いやすすぎ運転において、洗濯槽内の洗濯物は、パルセータの回転によって生じた水流に乗る。水流に乗った洗濯物は、バッフルに接触すると、バッフルの傾斜に沿ってせり上げられる。これにより、洗濯槽内で底部側にあった洗濯物が持ち上げられる。   The washing machine described in Patent Literature 1 includes a pulsator provided rotatably at the bottom of the washing tub, and a baffle provided on the inner peripheral surface of the washing tub. The baffle is provided so as to bulge toward the inner peripheral side of the washing tub in a posture inclined at a predetermined angle with respect to the rotation axis of the pulsator. In the easy-to-wash operation, the laundry in the washing tub rides on the water flow generated by the rotation of the pulsator. When the laundry on the water stream comes into contact with the baffle, it is lifted along the inclination of the baffle. Thereby, the laundry which was on the bottom side in the washing tub is lifted.

特開２００６−６８１８９号公報JP 2006-68189 A

洗浄機では、特許文献１の洗濯物のような洗浄対象物についての洗浄力の向上が、常に望まれる。   In the washing machine, it is always desired to improve the washing power of the washing object such as the laundry of Patent Document 1.

この発明は、かかる背景のもとでなされたもので、洗浄力の向上を図れる洗浄機を提供することを目的とする。   The present invention has been made under such a background, and an object thereof is to provide a cleaning machine capable of improving the cleaning power.

本発明は、洗浄対象物を収容する収容空間が内部に形成され、水が溜められる洗浄槽と、前記洗浄槽に溜められた水から水流を発生させる水流発生部材と、前記洗浄槽に設けられて前記収容空間に下側から対向した対向部であって、前記水流発生部材が発生させた水流を前記収容空間へ上向きに吐き出す吐出口が、前記収容空間を下側から臨むように形成された対向部と、前記吐出口よりも上側において前記収容空間内に突出し、前記収容空間における洗浄対象物の浮き上がりを防止するための浮き上がり防止部材とを含む、洗浄機である。   The present invention includes a cleaning tank in which a storage space for storing an object to be cleaned is formed, in which water is stored, a water flow generating member that generates a water flow from the water stored in the cleaning tank, and the cleaning tank. And a discharge port that is opposed to the storage space from below and discharges the water flow generated by the water flow generating member upward to the storage space so as to face the storage space from below. The cleaning machine includes a facing portion and a lifting prevention member that protrudes into the storage space above the discharge port and prevents the cleaning object from floating in the storage space.

また、本発明は、前記浮き上がり防止部材は、上下方向における前記収容空間の途中に設けられることを特徴とする。   Further, the present invention is characterized in that the lifting prevention member is provided in the middle of the accommodation space in the vertical direction.

また、本発明は、前記浮き上がり防止部材の下面部は、平坦面を含むことを特徴とする。   Further, the present invention is characterized in that the lower surface portion of the lifting prevention member includes a flat surface.

本発明によれば、洗浄槽に溜められた水から水流発生部材が発生させた水流は、洗浄槽の収容空間に下側から対向した対向部に形成された吐出口から収容空間へ上向きに吐き出されて、収容空間の洗浄対象物に下側から浴びせられる。これにより、洗浄対象物が洗浄される。
洗浄対象物は、下側から水流が浴びせられることによって、浮き上がろうとするが、吐出口よりも上側において収容空間内に突出した浮き上がり防止部材が、浮き上がろうとする洗浄対象物の先に位置するので、洗浄対象物が所定距離以上浮き上がることが防止される。これにより、吐出口から洗浄対象物までの距離が短く保たれるので、吐出口からの水流を勢いよく洗浄対象物に浴びせることによって、洗浄力の向上を図れる。
また、吐出口から上向きに吐き出された水流は、浮き上がり防止部材の下面部において対向部側へ跳ね返ってから、洗浄対象物に浴びせられることがある。これにより、洗浄対象物を、収容空間における対向部から浮き上がり防止部材までの領域において、効果的に撹拌できる。そのため、洗浄対象物の隅々に水流を浴びせることができるので、洗浄力の一層の向上を図れる。 According to the present invention, the water flow generated by the water flow generating member from the water stored in the cleaning tank is discharged upward from the discharge port formed in the facing portion facing the storage space of the cleaning tank from below to the storage space. Then, the object to be cleaned in the accommodation space is bathed from below. Thereby, the cleaning object is cleaned.
The object to be cleaned tends to float by being exposed to a water stream from below, but a lifting prevention member that protrudes into the accommodation space above the discharge port is located at the tip of the object to be cleaned. Therefore, the object to be cleaned is prevented from being lifted by a predetermined distance or more. As a result, the distance from the discharge port to the object to be cleaned is kept short, so that the cleaning power can be improved by immersing the water flow from the discharge port on the object to be cleaned.
In addition, the water flow discharged upward from the discharge port may splash on the object to be cleaned after bouncing back to the facing portion side on the lower surface portion of the lifting prevention member. Accordingly, the object to be cleaned can be effectively agitated in the region from the facing portion to the lifting prevention member in the accommodation space. As a result, water can be exposed to every corner of the object to be cleaned, so that the cleaning power can be further improved.

また、本発明によれば、浮き上がり防止部材は、上下方向における収容空間の途中に設けられるので、収納空間内の洗浄対象物が所定距離以上浮き上がることが確実に防止される。   Further, according to the present invention, since the lifting prevention member is provided in the middle of the storage space in the vertical direction, it is reliably prevented that the cleaning object in the storage space is lifted more than a predetermined distance.

また、本発明によれば、吐出口から上向きに吐き出された水流を、浮き上がり防止部材の下面部に含まれる平坦面によって、対向部側へ確実に跳ね返らせることができる。   Moreover, according to this invention, the water flow discharged upward from the discharge outlet can be reliably bounced to the opposing part side by the flat surface included in the lower surface part of the floating prevention member.

浮き上がり防止部材９は、洗浄槽２の収容空間２Ａの上下方向Ｚにおける途中、つまり上下方向Ｚにおける洗浄領域１３の途中、詳しくは、洗浄領域１３の略中央に設けられる。浮き上がり防止部材９は、対向部５の吐出口５Ａよりも上側Ｚ１において内槽４の内周面４Ｆから洗浄領域１３内へ径方向内側Ｒ１に突出したフランジ状に形成される。浮き上がり防止部材９は、対向部５の吐出口５Ａと周方向Ｓで同じ位置に少なくとも設けられる。吐出口５Ａと周方向Ｓで同じ位置にある浮き上がり防止部材９の下面部９Ａは、吐出口５Ａに上側Ｚ１から対向した状態にある。当該下面部９Ａにおいて少なくとも吐出口５Ａの真上に位置する領域には、水平方向Ｈに沿って平坦な平坦面９Ｂが設けられる。   The floating prevention member 9 is provided in the middle of the cleaning space 13 in the vertical direction Z of the accommodation space 2A of the cleaning tank 2, that is, in the middle of the cleaning region 13 in the vertical direction Z. The floating prevention member 9 is formed in a flange shape that protrudes radially inward R1 from the inner peripheral surface 4F of the inner tank 4 into the cleaning region 13 on the upper side Z1 of the discharge port 5A of the facing portion 5.

A flat surface 9B that is flat along the horizontal direction H is provided in a region located at least directly above the discharge port 5A in the lower surface portion 9A.

揚水部材６において上下方向Ｚで浮き上がり防止部材９とほぼ同じ位置に設けられた上端部６Ａの突出部６Ｂも、浮き上がり防止部材９とみなしてもよい。この場合、突出部６Ｂの下面部は、前述した平坦面９Ｂを含んだ下面部９Ａとして機能する。   The protruding portion 6 </ b> B of the upper end portion 6 </ b> A provided in the pumping member 6 at substantially the same position as the lifting prevention member 9 in the vertical direction Z may be regarded as the lifting prevention member 9. In this case, the lower surface portion of the protruding portion 6B functions as the lower surface portion 9A including the flat surface 9B described above.

外槽３の内部空間３Ｄおよび内槽４の内部空間４Ｄに水が溜まった状態では、配置領域１２内の水流発生部材８は、水に浸かった状態にある。この状態でモータ７が駆動されると、モータ７の駆動力が第２伝達軸１６から水流発生部材８に伝達されることによって、水流発生部材８が、回転軸線Ｊまわりに回転する。水流発生部材８が回転するとき、内槽４は、停止した状態にある。取込空間２５に存在する水は、太い実線の矢印で示すように、水流発生部材８の回転による遠心力によって各水路２６に流れ込んで回転軸線Ｊから離れるように各水路２６を流れる。配置領域１２において水流発生部材８よりも下側Ｚ２に存在する水は、各水路２６における流れに引っ張られて回転軸線Ｊから離れるように流れる。このように配置領域１２の水が流れると、径方向Ｒにおける外槽３の円周壁３Ｂと内槽４の円周壁４Ｂとの隙間２７に存在する水が、回転する水流発生部材８に引き寄せられて、破線の矢印で示すように、隙間２７を通って下降し、外槽３の底壁３Ｃと内槽４の底壁４Ｃとの隙間２８に到達した後に、底壁４Ｃの貫通穴４Ｅから配置領域１２に取り込まれる。   In a state where water has accumulated in the internal space 3D of the outer tub 3 and the internal space 4D of the inner tub 4, the water flow generating member 8 in the arrangement region 12 is in a state immersed in water. When the motor 7 is driven in this state, the driving force of the motor 7 is transmitted from the second transmission shaft 16 to the water flow generating member 8 so that the water flow generating member 8 rotates around the rotation axis J. When the water flow generating member 8 rotates, the inner tank 4 is in a stopped state. The water existing in the intake space 25 flows into each water channel 26 by the centrifugal force due to the rotation of the water flow generating member 8 and flows away from the rotation axis J as indicated by a thick solid arrow. In the arrangement region 12, the water present on the lower side Z <b> 2 from the water flow generating member 8 is pulled by the flow in each water channel 26 and flows away from the rotation axis J. Thus, when the water of the arrangement | positioning area | region 12 flows, the water which exists in the clearance gap 27 of the circumferential wall 3B of the outer tank 3 in the radial direction R and the circumferential wall 4B of the inner tank 4 is attracted to the rotating water flow generation member 8. As shown by the broken arrow, after descending through the gap 27 and reaching the gap 28 between the bottom wall 3C of the outer tub 3 and the bottom wall 4C of the inner tub 4, from the through hole 4E of the bottom wall 4C. It is taken into the arrangement area 12.

取込空間２５から各水路２６に流れ込んだ水や、配置領域１２において水流発生部材８よりも下側Ｚ２において回転軸線Ｊから離れるように流れた水、つまり、洗浄槽２に溜められた水は、水流発生部材８の回転による遠心力によって水流となって、水流発生部材８よりも径方向外側Ｒ２へ流れる。この水流は、その先にあるガイド部４Ｇによって、対向部５の吐出口５Ａまたは揚水路１４の吸込口１４Ａへ向けて上側Ｚ１へ導かれる。吐出口５Ａへ導かれた水流は、１点鎖線の矢印で示すように、吐出口５Ａから洗浄領域１３へ上向きに勢いよく吐き出される。揚水路１４の吸込口１４Ａへ導かれた水流は、２点鎖線の矢印で示すように、吸込口１４Ａから揚水路１４内を上昇し、揚水部材６の散水口６Ｃから勢いよく吐き出されて洗浄領域１３内に降り注ぐ。このように水流発生部材８の回転に応じて吐出口５Ａおよび散水口６Ｃから洗浄領域１３に吐き出された水流が内部空間４Ｄの洗浄対象物Ｑに浴びせられたり、洗浄対象物Ｑを撹拌したりすることによって、洗浄対象物Ｑが洗浄される。また、洗剤が水流に含まれてもよく、この場合、洗浄対象物Ｑの汚れが洗剤によって分解される。   The water that flows into each water channel 26 from the intake space 25 and the water that flows away from the rotation axis J on the lower side Z2 of the water flow generating member 8 in the arrangement region 12, that is, the water stored in the cleaning tank 2 are The water flow generation member 8 becomes a water flow by the centrifugal force generated by the rotation of the water flow generation member 8, and flows to the radially outer side R <b> 2 from the water flow generation member 8. This water flow is guided to the upper side Z1 toward the discharge port 5A of the facing portion 5 or the suction port 14A of the pumping channel 14 by the guide portion 4G at the tip thereof. The water flow guided to the discharge port 5A is vigorously discharged upward from the discharge port 5A to the cleaning region 13 as indicated by a one-dot chain line arrow. The water flow guided to the suction port 14A of the pumping path 14 ascends in the pumping path 14 from the suction port 14A, and is discharged from the sprinkling port 6C of the pumping member 6 and washed as indicated by a two-dot chain line arrow. Pour into area 13. In this way, the water flow discharged from the discharge port 5A and the sprinkling port 6C to the cleaning region 13 in response to the rotation of the water flow generating member 8 is applied to the cleaning target Q in the internal space 4D, or the cleaning target Q is stirred. By doing so, the cleaning object Q is cleaned. Further, a detergent may be included in the water flow, and in this case, the dirt of the cleaning object Q is decomposed by the detergent.

洗浄対象物Ｑは、吐出口５Ａからの水流が下側Ｚ２から浴びせられることによって、浮き上がろうとするが、吐出口５Ａよりも上側Ｚ１の浮き上がり防止部材９が、浮き上がろうとする洗浄対象物Ｑの先に位置するので、洗浄領域１３つまり洗浄槽２の収容空間２Ａにおいて洗浄対象物Ｑが所定距離以上浮き上がることが防止される。特に、浮き上がり防止部材９は、上下方向Ｚにおける収容空間２Ａの途中に設けられるので、収容空間２Ａ内の洗浄対象物Ｑが所定距離以上浮き上がることが確実に防止される。よって、洗浄対象物Ｑが浮き上がり防止部材９よりも下側Ｚ２に留められることによって、吐出口５Ａから洗浄対象物Ｑまでの上下の距離が短く保たれるので、吐出口５Ａからの水流を勢いよく洗浄対象物Ｑに浴びせることによって、洗浄力の向上を図れる。   The object Q to be cleaned tends to be lifted when the water flow from the discharge port 5A is exposed to the lower side Z2, but the lift prevention member 9 on the upper side Z1 from the discharge port 5A is to be cleaned. Since the object Q is located at the tip of the object Q, the object Q to be cleaned is prevented from being lifted more than a predetermined distance in the cleaning region 13, that is, the storage space 2A of the cleaning tank 2. In particular, since the lifting prevention member 9 is provided in the middle of the accommodation space 2A in the vertical direction Z, the object Q to be cleaned in the accommodation space 2A is reliably prevented from being lifted by a predetermined distance or more. Therefore, the vertical distance from the discharge port 5A to the cleaning object Q is kept short by the cleaning object Q being held on the lower side Z2 with respect to the lifting prevention member 9, so that the water flow from the discharge port 5A is vigorous. It is possible to improve the cleaning power by often bathing the object Q to be cleaned.

また、吐出口５Ａから上向きに吐き出された水流は、浮き上がり防止部材９の下面部９Ａにおいて対向部５側へ跳ね返ってから、洗浄対象物Ｑに浴びせられることがある。これにより、洗浄対象物Ｑを、収容空間２Ａにおける対向部５から浮き上がり防止部材９までの領域において、効果的に撹拌できる。そのため、洗浄対象物Ｑの隅々に水流を浴びせることができるので、洗浄力の一層の向上を図れる。特に、吐出口５Ａから上向きに吐き出された水流を、下面部９Ａに含まれる水平な平坦面９Ｂによって、対向部５側へ確実に跳ね返らせることができる。   Further, the water flow discharged upward from the discharge port 5 </ b> A may be splashed on the cleaning object Q after it bounces back to the facing portion 5 side on the lower surface portion 9 </ b> A of the lifting prevention member 9. Thereby, the to-be-cleaned object Q can be stirred effectively in the area | region from the opposing part 5 in the accommodation space 2A to the floating prevention member 9. FIG. Therefore, since the water flow can be poured on every corner of the cleaning object Q, the cleaning power can be further improved. In particular, the water flow discharged upward from the discharge port 5A can be reliably rebounded to the facing portion 5 side by the horizontal flat surface 9B included in the lower surface portion 9A.

洗浄領域１３の水は、内槽４の円周壁４Ｂの貫通穴４Ｅから外槽３の円周壁３Ｂと内槽４の円周壁４Ｂとの隙間２７に流出した後に、回転する水流発生部材８によって配置領域１２に取り込まれて水流となり、再び洗浄領域１３に吐き出される。つまり、水流発生部材８の回転中において、内槽４の内部空間４Ｄにおける水は、水流となって配置領域１２と洗浄領域１３との間で循環する。なお、洗浄対象物Ｑの洗浄後には、水流発生部材８が停止した状態で内槽４が回転し、その遠心力によって洗浄対象物Ｑを脱水してもよい。   The water in the cleaning region 13 flows into the gap 27 between the circumferential wall 3B of the outer tub 3 and the circumferential wall 4B of the inner tub 4 from the through hole 4E of the circumferential wall 4B of the inner tub 4, and then the water flow generating member 8 rotates. It is taken into the arrangement area 12 and becomes a water flow, and is discharged to the cleaning area 13 again. That is, during the rotation of the water flow generating member 8, the water in the internal space 4 </ b> D of the inner tank 4 is circulated between the arrangement region 12 and the cleaning region 13 as a water flow. In addition, after washing | cleaning of the washing | cleaning target object Q, the inner tank 4 may rotate in the state which the water flow generation member 8 stopped, and the washing | cleaning target object Q may be spin-dry | dehydrated with the centrifugal force.

この発明は、以上に説明した実施形態に限定されるものではなく、請求項に記載の範囲内において種々の変更が可能である。   The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims.

例えば、浮き上がり防止部材９は、内槽４とともに回転することによって洗浄対象物Ｑを撹拌するバッフルの機能を兼ねてもよい。また、バランスリング１１と同様にリング状に形成されたリング部材がバランスリング１１よりも下側Ｚ２に配置され、このリング部材の一部が浮き上がり防止部材９を構成してもよい。   For example, the lifting prevention member 9 may also function as a baffle that agitates the cleaning object Q by rotating together with the inner tank 4. Further, a ring member formed in a ring shape similarly to the balance ring 11 may be disposed on the lower side Z <b> 2 than the balance ring 11, and a part of the ring member may constitute the lifting prevention member 9.

浮き上がり防止部材９は、外槽３の開口３Ａの内周縁３Ｅよりも径方向内側Ｒ１へはみ出さないことが好ましい。つまり、浮き上がり防止部材９における径方向内側Ｒ１の周縁部は、開口３Ａの内周縁３Ｅよりも径方向外側Ｒ２へずれて配置されることが好ましい。これにより、開口３Ａでの洗浄対象物Ｑの出し入れの際に浮き上がり防止部材９が邪魔になることを防止できる。   It is preferable that the floating prevention member 9 does not protrude to the radially inner side R1 from the inner peripheral edge 3E of the opening 3A of the outer tub 3. In other words, it is preferable that the peripheral edge portion on the radially inner side R1 of the lifting prevention member 9 is arranged to be shifted to the radially outer side R2 from the inner peripheral edge 3E of the opening 3A. Thereby, it is possible to prevent the floating prevention member 9 from getting in the way when the cleaning object Q is put in and out of the opening 3A.

図２は、変形例に係る洗浄機１の内部構造の縦断面図である。図２において、以上で説明した部分と同一の部分には同一番号を付して、当該部分についての説明は省略する。   FIG. 2 is a longitudinal sectional view of the internal structure of the washing machine 1 according to the modification. In FIG. 2, the same parts as those described above are denoted by the same reference numerals, and description thereof is omitted.

変形例に係る洗浄機１では、例えば上下方向Ｚにおける内槽４の寸法が小さいことにより、図２に示すように外槽３の開口３Ａと内槽４の開口４Ａとの間の上下の間隔が大きい。この場合、内槽４の内部空間４Ｄにおいて対向部５よりも上側Ｚ１の洗浄領域１３と、外槽３の内部空間３Ｄにおいて開口４Ａを介して洗浄領域１３に上側Ｚ１から連通した上側空間３Ｆとが、前述した洗浄槽２の収容空間２Ａを構成する。外槽３の円周壁３Ｂにおいて開口４Ａよりも上側Ｚ１の部分は、収容空間２Ａ内の洗浄対象物Ｑを機外から目視できるように、透明または半透明であってもよい。   In the washing machine 1 according to the modification, for example, the vertical dimension between the opening 3A of the outer tub 3 and the opening 4A of the inner tub 4 as shown in FIG. Is big. In this case, in the internal space 4D of the inner tub 4, the cleaning region 13 on the upper side Z1 than the facing portion 5, and in the internal space 3D of the outer tub 3, the upper space 3F communicated from the upper side Z1 to the cleaning region 13 through the opening 4A. However, it constitutes the housing space 2A of the cleaning tank 2 described above. The portion of the circumferential wall 3B of the outer tub 3 that is on the upper side Z1 from the opening 4A may be transparent or translucent so that the object Q to be cleaned in the accommodation space 2A can be seen from outside the apparatus.

変形例に係る洗浄機１では、内槽４の円周壁４Ｂの上端部に取り付けられたバランスリング１１は、上下方向Ｚにおける収容空間２Ａの途中、詳しくは上下方向Ｚにおける収容空間２Ａの略中央に位置して収容空間２Ａ内に径方向外側Ｒ２から突出することによって、前述した浮き上がり防止部材９の機能も兼ねる。換言すれば、浮き上がり防止部材９が、バランスリング１１によって構成される。この場合、バランスリング１１の下面部は、前述した平坦面９Ｂを含んだ下面部９Ａとして機能する。洗浄対象物Ｑは、吐出口５Ａからの水流が下側Ｚ２から浴びせられることによって、浮き上がろうとするが、バランスリング１１が、浮き上がろうとする洗浄対象物Ｑの先に位置するので、洗浄対象物Ｑが所定距離以上浮き上がることが防止される。   In the cleaning machine 1 according to the modification, the balance ring 11 attached to the upper end portion of the circumferential wall 4B of the inner tub 4 is in the middle of the accommodation space 2A in the up-down direction Z, more specifically in the approximate center of the accommodation space 2A in the up-down direction Z. By projecting from the radially outer side R2 into the accommodating space 2A, the function of the above-described lifting prevention member 9 is also achieved. In other words, the lifting prevention member 9 is constituted by the balance ring 11. In this case, the lower surface portion of the balance ring 11 functions as the lower surface portion 9A including the flat surface 9B described above. The object Q to be cleaned tends to float when the water flow from the discharge port 5A is exposed to the lower side Z2, but the balance ring 11 is positioned at the tip of the object Q to be lifted. It is possible to prevent the cleaning object Q from floating over a predetermined distance.

回転軸線Ｊは、上下方向Ｚに対して傾斜して配置されてもよく、この場合、対向部５および水流発生部材８は、水平方向Ｈに対して傾斜して配置されることによって、回転軸線Ｊと直交した姿勢を維持する。   The rotation axis J may be arranged to be inclined with respect to the vertical direction Z. In this case, the opposing portion 5 and the water flow generating member 8 are arranged to be inclined with respect to the horizontal direction H, whereby the rotation axis Maintain posture orthogonal to J.
