Description
本発明は洗濯機の技術分野に属し、具体的には、回転可能且つ貯水可能な内槽のみが設けられる洗濯機に関し、特に、洗濯機の排水構造に関する。 The present invention relates to the technical field of washing machines, and more particularly to a washing machine provided with only a rotatable and water-storing inner tub, and more particularly to a drainage structure of a washing machine.
従来技術において、一般的に、ドラム洗濯機は互いに嵌装される内槽と外槽を含む。外槽は密封されて貯水に用いられる。また、内槽には衣類が投入され、内槽を回転させることで衣類を打ち付けて洗浄を実施する。且つ、内槽には脱水孔が設けられる。これにより、外槽内の水が脱水孔から内槽に流入して内槽内の衣類を浸漬する。また、内槽内の水は脱水孔から外槽に流出する。且つ、内槽内の衣類の水分は内槽の高速回転時に脱水孔から外槽に排出される。こうして、衣類を洗浄するとの目的が実現される。 In the prior art, a drum washing machine generally includes an inner tub and an outer tub fitted together. The outer tank is sealed and used for water storage. In addition, clothes are put into the inner tank, and by rotating the inner tank, the clothes are hit and washed. In addition, a dehydration hole is provided in the inner tank. As a result, the water in the outer tub flows into the inner tub from the dehydration hole to immerse the clothes in the inner tub. Further, the water in the inner tank flows out to the outer tank through the dehydration hole. In addition, the water content of the clothes in the inner tank is discharged from the dehydration hole to the outer tank when the inner tank rotates at high speed. Thus, the purpose of cleaning clothes is achieved.
しかし、内槽と外槽は互いに嵌装されるため、洗濯機の使用過程で内槽と外槽の間に汚れが溜まりやすい。また、内槽と外槽が互いに嵌装されることから、ユーザは内槽の外壁と外槽の内壁をクリーニングする術がない。よって、洗濯機内部の細菌が増殖し、洗濯機の洗濯効率や衣類洗浄後の清潔度が低下する。 However, since the inner tub and the outer tub are fitted to each other, dirt is likely to accumulate between the inner tub and the outer tub during the process of using the washing machine. Further, since the inner tank and the outer tank are fitted to each other, the user has no way to clean the outer wall of the inner tank and the inner wall of the outer tank. Therefore, the bacteria inside the washing machine multiply, and the washing efficiency of the washing machine and the cleanliness after washing the clothes are reduced.
また、上述した従来の洗濯機では、内槽の外部に外槽が嵌装されており、洗濯機の洗浄過程では内槽が回転することで衣類を打ち付けて洗浄する。そのため、洗濯機の洗浄容量は内槽が基準となり、洗濯機の内部空間の利用率が低い。よって、従来をベースにした場合、洗濯機の洗浄容量を拡大することは不可能である。 Further, in the above-described conventional washing machine, the outer tub is fitted outside the inner tub, and in the washing process of the washing machine, the inner tub is rotated to hit and wash the clothes. Therefore, the washing capacity of the washing machine is based on the inner tub, and the utilization rate of the internal space of the washing machine is low. Therefore, it is impossible to expand the washing capacity of the washing machine based on the conventional method.
上記に鑑みて、内槽と外槽を一体化し、内槽を密封容器とすることで水と衣類を投入可能としつつ、回転により衣類を打ち付けて洗浄を実施可能な洗濯機を如何にして設置するか、及び、洗濯機に外槽を設けないか、外槽と洗濯機のハウジングを一体的に設けることで、洗濯機の内槽を拡大して洗濯機の洗浄容量を増大可能とすることが、研究開発の焦点となっている。 In view of the above, how to install a washing machine that can wash clothes by hitting clothes by rotating while making it possible to put water and clothes by integrating the inner tank and the outer tank and making the inner tank a sealed container Whether the outer tub is not provided in the washing machine or the outer tub and the housing of the washing machine are integrally provided, so that the inner tub of the washing machine can be expanded to increase the washing capacity of the washing machine. However, it is the focus of research and development.
しかし、内槽は洗浄水を貯めるだけでなく、回転により槽内の衣類を打ち付けて洗浄を実施する必要がある。そのため、上記洗濯機に適用される排水構造を如何に設置するかもまた喫緊に解決を要する難題となっている However, it is necessary for the inner tank not only to store the cleaning water, but also to spin the clothes to hit the clothes in the tank for cleaning. Therefore, how to install the drainage structure applied to the above-mentioned washing machine has become an urgent issue that requires immediate solution.
上記の技術的欠点に鑑みて、本発明を提案する。 In view of the above technical drawbacks, the present invention is proposed.
本発明は、従来技術に存在する上記の瑕疵を解消するために、洗濯機の排水構造を提供することを目的とする。本発明で記載する洗濯機の排水構造では、内槽の最底部に排水弁を設けるとともに、排水弁に対応するバルブプラグ開放機構を洗濯機に設け、洗濯機の内槽を相応の位置に位置決めしてからバルブプラグ開放機構が排水弁のバルブプラグを開放することで、内槽内に貯えられた洗浄水を排出するとの課題を解決する。これにより、回転可能な内槽槽口を密封し、洗濯機の正常な動作過程では内槽内に供給された水を排出せず、洗濯機の排水時には内槽内の洗浄水を排水弁経由で排出するとの目的が実現される。且つ、ドラム洗濯機の内槽と外槽を一体化することで、洗濯機の洗浄容量を拡大するとの目的が実現される。 An object of the present invention is to provide a drainage structure for a washing machine in order to eliminate the above defects existing in the prior art.

As a result, the rotatable inner tub mouth is sealed, the water supplied to the inner tub is not discharged during normal operation of the washing machine, and the washing water in the inner tub is drained through the drain valve when the washing machine drains. The purpose of discharging at is realized. In addition, by integrating the inner tub and the outer tub of the drum washing machine, the purpose of expanding the washing capacity of the washing machine is realized.

更に、前記バルブコア開放機構は、内槽支持部材に装着される電磁石を含む。内槽が固定排水位置まで回転したときに排水弁と電磁石が同軸線方向に配置されるよう、前記電磁石は排水弁に対応して設けられる。電磁石の通電後にバルブコアに電磁斥力が付与されて、バルブコアが内槽の内側方向へと押し動かされることで排水弁が開放され、排水が行われるよう、排水弁のバルブコアには磁石が設けられるか、バルブコア全体が磁石から構成される。 Further, the valve core opening mechanism includes an electromagnet attached to the inner tank supporting member. The electromagnet is provided corresponding to the drain valve so that the drain valve and the electromagnet are arranged coaxially when the inner tank is rotated to the fixed drain position. An electromagnetic repulsive force is applied to the valve core after energizing the electromagnet, and the valve core is pushed toward the inner side of the inner tank to open the drain valve and drain the valve. The entire valve core is composed of magnets.

The washing machine includes a housing 2, and an inner tub 1 is provided inside the housing 2. The axis of the inner tank 1 extends horizontally or is inclined downward from the front to the rear. A front end of the inner tank 1 is an inner tank opening 101 having an opening, and a rear end thereof is an inner tank bottom 102 provided in a sealed manner. No through hole is provided in the tank wall of the inner tank 1 so that the inside of the inner tank 1 constitutes a sealed container having an opening provided only in the front portion. A door 4 that can be opened to the outside is attached to the front end of the housing 2 of the washing machine. Therefore, the purpose of closing the door 4 to seal the inner tub opening 101 and opening the door 4 to put the clothes into the inner tub 1 from the inner tub opening 101 can be achieved. The rear end of the inner tub 1 is mounted in the housing 2 of the washing machine via the inner tub support member 3. The inner tank support member 3 is provided coaxially at the rear end of the inner tank 1. The upper and lower ends of the inner tank supporting member 3 are respectively bent toward the tank opening at the front end of the inner tank 1.

In addition, the shaft of the drive motor 5 is rotatable with respect to the inner tank support member 3. Thus, the inner tub 1 and the drive motor 5 are mounted on the inner tub support member 3, and the inner tub 1 is independently rotated by the action of the drive motor 5 to realize the purpose of cleaning the clothes inside.
本発明の実施例では、洗濯機の内槽内に供給された水を排出するとともに、洗濯機の動作過程では、内槽を密封して貯水することで正常な洗浄を行うべく、以下のように設置する。 In the embodiment of the present invention, the water supplied into the inner tub of the washing machine is discharged, and in the process of operation of the washing machine, the inner tub is sealed to store water in order to perform normal washing as follows. To install.
洗濯機の排水構造において、洗濯機のハウジング2の内部には内槽1が装着されている。内槽1には排水口23が設けられ、排水口23に常時閉状態の排水弁24が装着されている。洗濯機には、内槽1を固定排水位置まで回転させて固定する位置決めロック機構が設けられている。また、洗濯機が排水状態の場合に、内槽1が固定排水位置まで回転したあと、排水弁24を開放することで内槽内の洗浄水を排出するよう、洗濯機には、内槽1が固定排水位置まで回転したあとに排水弁24を開放するバルブコア開放機構が設けられている。 In a drainage structure of a washing machine, an inner tub 1 is mounted inside a housing 2 of the washing machine. The inner tank 1 is provided with a drain port 23, and the drain port 23 is equipped with a drain valve 24 which is in a normally closed state. The washing machine is provided with a positioning lock mechanism that rotates and fixes the inner tub 1 to a fixed drainage position. In addition, when the washing machine is in the drainage state, after the inner tub 1 is rotated to the fixed drainage position, the drainage valve 24 is opened to drain the wash water in the inner tub. A valve core opening mechanism is provided for opening the drain valve 24 after rotating to the fixed drain position.
洗濯機の正常な動作過程では、排水弁を閉止して排水口を閉止状態とするため、内槽内の水が排水口から流出することはない。一方、洗濯機が排水状態の場合には、洗濯機の内槽が位置決めロック機構の作用によって固定排水位置まで回転し、洗濯機のバルブコア開放機構が起動することで排水弁のバルブプラグが開放される。これにより、排水口が開放状態となって内槽内の水が排水口から流出する。 In the normal operation process of the washing machine, the drain valve is closed to close the drain port, so that the water in the inner tub does not flow out from the drain port. On the other hand, when the washing machine is draining, the inner tub of the washing machine is rotated to the fixed drainage position by the action of the positioning lock mechanism, and the valve core opening mechanism of the washing machine is activated to open the valve plug of the drainage valve. It As a result, the drain port is opened and the water in the inner tank flows out from the drain port.
上記のように設けることで、洗濯機が正常な動作状態の場合には排水弁が閉止状態となり、洗濯機の排水時には、位置決めロック機構とバルブプラグ開放機構との連携によって排水弁が開放状態となる。よって、内槽の正常な回転時に内槽内に貯えられた水が排水口から流出することはない。これにより、内槽の回転過程では内槽を密封し、排水時には、排水弁を開放することで内槽内に貯えられた水を正常に排出するとの効果が実現される。従って、内槽の回転及び貯水という2つの効果を有する洗濯機による正常な排水との目的が達せられる。且つ、内槽の外部に外槽を嵌装する必要がなく、内槽の容積が大きくなるため、洗濯機の洗浄容量が増加する。 By providing as described above, the drain valve is closed when the washing machine is in a normal operating state, and when the washing machine is draining, the drain valve is opened by the cooperation of the positioning lock mechanism and the valve plug opening mechanism. Become. Therefore, the water stored in the inner tank does not flow out from the drainage port when the inner tank normally rotates. As a result, the effect that the water stored in the inner tank is normally discharged by sealing the inner tank during the rotation process of the inner tank and opening the drain valve at the time of draining is realized. Therefore, the purpose of normal drainage by the washing machine having two effects of rotation of the inner tub and storage of water can be achieved. Moreover, since it is not necessary to fit the outer tub outside the inner tub, and the volume of the inner tub is increased, the washing capacity of the washing machine is increased.
図1〜図4に示すように、本発明では、洗濯機の排水構造について説明する。洗濯機のハウジング2の内部には内槽1が装着されている。内槽1には排水口23が設けられ、排水口23に常時閉状態の排水弁24が装着されている。洗濯機には、内槽1を固定排水位置まで回転させて固定する位置決めロック機構が設けられている。また、洗濯機が排水状態の場合に、内槽1が固定排水位置まで回転したあと、排水弁24を開放することで内槽内の洗浄水を排出するよう、洗濯機には、内槽1が固定排水位置まで回転したあとに排水弁24を開放するバルブコア開放機構が設けられている。 As shown in FIGS. 1 to 4, in the present invention, a drainage structure of a washing machine will be described. The inner tub 1 is mounted inside the housing 2 of the washing machine. The inner tank 1 is provided with a drain port 23, and the drain port 23 is equipped with a drain valve 24 which is in a normally closed state. The washing machine is provided with a positioning lock mechanism that rotates and fixes the inner tub 1 to a fixed drainage position. In addition, when the washing machine is in the drainage state, after the inner tub 1 is rotated to the fixed drainage position, the drainage valve 24 is opened to drain the wash water in the inner tub. A valve core opening mechanism is provided for opening the drain valve 24 after rotating to the fixed drain position.
本実施例において、前記排水口23は、内槽1の外側壁又は前後端の外周箇所に設けられる。好ましくは、内槽1は一端の直径が小さく、一端の直径が大きなテーパー状の槽であり、前記排水口23が内槽1における大径端の外周箇所に設けられる。排水口をテーパー状の内槽の大径端に設けることで、内槽内の水流は排水口に集まるよう流動するため、内槽内の水流を全て排水口から排出するとの目的が実現される。 In the present embodiment, the drain port 23 is provided on the outer wall of the inner tank 1 or on the outer peripheral portion of the front and rear ends. Preferably, the inner tank 1 is a tapered tank having a small diameter at one end and a large diameter at one end, and the drain port 23 is provided at the outer peripheral portion of the large diameter end of the inner tank 1. By providing the drain port at the large diameter end of the tapered inner tank, the water flow in the inner tank flows so as to gather in the drain port, so the purpose of discharging all the water flow in the inner tank from the drain port is realized. ..
本実施例において、内槽1は、後端が内槽底102から構成され、前端が内槽槽口101から構成されるとともに、これらが内槽の側壁を介して接続される。前記内槽の側壁は、内槽槽口101から内槽底102に向かって徐々に直径が大きくなるテーパー状面である。内槽底102の外周部には、水平に貫通するよう設置される排水口23が設けられ、排水口23に排水弁24が設けられる。排水弁24は、排水口23を覆うバルブコア25を含む。バルブコア25は、位置規制バネ26の作用により内側から外側に向かって排水口23を塞ぐよう、位置規制バネ26を介して内槽底102に接続される。位置規制バネを介してバルブコアを内槽底に接続することで、位置規制バネがバルブコアに対し内槽の外部に向かう方向の弾性張力を付与する。これにより、バルブコアが弾性力の作用によって内槽底にしっかりと密着し、排水口を塞ぐため、排水口を密封するとの目的が実現される。 In this embodiment, the rear end of the inner tank 1 is composed of the inner tank bottom 102, the front end thereof is composed of the inner tank port 101, and these are connected via the side wall of the inner tank. The side wall of the inner tank is a tapered surface whose diameter gradually increases from the inner tank opening 101 toward the inner tank bottom 102. A drain port 23 is provided on the outer peripheral portion of the inner tank bottom 102 so as to penetrate horizontally, and a drain valve 24 is provided at the drain port 23. The drainage valve 24 includes a valve core 25 that covers the drainage port 23. The valve core 25 is connected to the inner tank bottom 102 via the position regulation spring 26 so that the drainage port 23 is closed from the inner side to the outer side by the action of the position regulation spring 26. By connecting the valve core to the bottom of the inner tank via the position restricting spring, the position restricting spring applies elastic tension to the valve core in the direction toward the outside of the inner tank. As a result, the valve core firmly adheres to the bottom of the inner tank by the action of the elastic force and closes the drain port, so that the purpose of sealing the drain port is realized.
本実施例において、内槽1の排水口23は、内側から外側に向かって徐々に拡大するテーパー状の孔として設けられる。テーパー状の孔の小径端は密封されており、テーパー状の孔の側壁には内槽1の内外を連通する貫通孔が設けられている。バルブコア25は、テーパー状の孔の大径端を覆うプレート材構造をなしている。また、テーパー状の孔には、軸線に沿って延伸する位置規制バネ26が設けられている。位置規制バネ26は、一端がテーパー状の孔の小径端における密封部に接続され、他端がバルブコア25に接続される。位置規制バネ26は、伸長状態の場合に、バルブコア25に対し内槽1の外部方向に向かう推力を付与するため、バルブコア25が排水口24を塞ぐ。 In this embodiment, the drainage port 23 of the inner tank 1 is provided as a tapered hole that gradually expands from the inside to the outside. A small diameter end of the tapered hole is sealed, and a side wall of the tapered hole is provided with a through hole that communicates the inside and the outside of the inner tank 1. The valve core 25 has a plate material structure that covers the large-diameter end of the tapered hole. In addition, a position regulating spring 26 extending along the axis is provided in the tapered hole. The position regulating spring 26 has one end connected to the sealing portion at the small diameter end of the tapered hole and the other end connected to the valve core 25. The position regulation spring 26 applies a thrust force toward the outside of the inner tank 1 to the valve core 25 in the expanded state, so that the valve core 25 closes the drain port 24.
本実施例において、内槽1の後端には内槽支持部材3が設けられている。内槽支持部材3は、制震吊りバネ6及び/又は制震支持ロッド7を介して洗濯機のハウジング2内に装着される。また、バルブコア開放機構が内槽支持部材3に装着される。 In this embodiment, an inner tank supporting member 3 is provided at the rear end of the inner tank 1. The inner tub support member 3 is mounted in the housing 2 of the washing machine via the vibration control suspension spring 6 and/or the vibration control support rod 7. Further, the valve core opening mechanism is attached to the inner tank support member 3.
本実施例において、内槽1が固定排水位置にある場合、排水口23は内槽1の最も低い箇所に位置する。そのため、内槽1内の水流は排水口23に集まるよう流動し、排水弁24が開放された排水口23から外部に流出する。前記バルブコア開放機構は、内槽支持部材3のうち内槽1から離間する側に装着されるとともに、内槽1の外周に対向するよう設けられる。内槽1が固定排水位置にある場合、排水口23はバルブコア開放機構のコネクティングロッド28に対し同軸に設けられる。よって、コネクティングロッド28がステッピングモータ及び回転ローラ27の働きで軸方向に伸縮し、排水弁24のバルブコア25を内槽1の内部方向へ移動させることで、排水口23が開放される。 In this embodiment, when the inner tank 1 is at the fixed drainage position, the drainage port 23 is located at the lowest position of the inner tank 1. Therefore, the water flow in the inner tank 1 flows so as to gather in the drain port 23, and flows out to the outside from the drain port 23 in which the drain valve 24 is opened. The valve core opening mechanism is mounted on the side of the inner tank supporting member 3 which is separated from the inner tank 1, and is provided so as to face the outer periphery of the inner tank 1. When the inner tank 1 is at the fixed drainage position, the drainage port 23 is provided coaxially with the connecting rod 28 of the valve core opening mechanism. Therefore, the connecting rod 28 expands and contracts in the axial direction by the action of the stepping motor and the rotating roller 27, and moves the valve core 25 of the drain valve 24 toward the inside of the inner tank 1, whereby the drain port 23 is opened.
図4及び図5に示すように、本実施例において、バルブコア開放機構は、内槽支持部材3に装着されるステッピングモータを含む。ステッピングモータの出力端には、同軸に固定接続される回転ローラ27が装着されており、回転ローラ27の外周箇所にコネクティングロッド28の一端がヒンジ接続される。また、コネクティングロッド28の他端は、内槽支持部材3に設けられる位置規制孔に挿通され、排水弁23に向かって伸縮可能に移動する。これにより、バルブコア25が内槽1内に向かって移動し、排水弁24を開放することで排水がなされる。 As shown in FIGS. 4 and 5, in this embodiment, the valve core opening mechanism includes a stepping motor mounted on the inner tank support member 3. A rotary roller 27, which is coaxially fixedly connected, is attached to an output end of the stepping motor, and one end of a connecting rod 28 is hingedly connected to an outer peripheral portion of the rotary roller 27. Further, the other end of the connecting rod 28 is inserted into a position regulating hole provided in the inner tank supporting member 3 and moves to the drain valve 23 so as to be expandable and contractable. As a result, the valve core 25 moves toward the inside of the inner tank 1, and the drain valve 24 is opened to drain water.
本実施例では、内槽1の排水口23の外部に対応して集水槽30が設けられている。集水槽30の底部は、内槽1の排水口23から排出される水流を収集して排出するよう、洗濯機の排水管31に連通している。 In this embodiment, a water collecting tank 30 is provided outside the drain port 23 of the inner tank 1. The bottom of the water collecting tank 30 communicates with the drain pipe 31 of the washing machine so as to collect and discharge the water flow discharged from the drain port 23 of the inner tank 1.
本実施例において、排水口23は内槽底102の外周箇所に設けられる。内槽1が固定排水位置にあるとき、排水口23は内槽1の軸線の真下まで回転する。集水槽30は、排水口23の下方に対応して設けられる凹槽を含む。凹槽の後側壁は、排水口23の後側まで上方に向かって垂直に延伸するとともに、排水口23と一定の間隔を隔てている。これにより、排水口23から流出した水流が集水槽30に落下するよう案内されるため、水平に設けられた排水口から後方に流れ出した排水が洗濯機の外部に飛散するとの事態が回避される。且つ、集水槽30の前側壁と洗濯機の内槽1の下部は密着するか、極めて小さな距離を隔てている。これにより、集水槽30内の水が前端から飛散することがないため、内槽からの排水が溢流するとの事態が回避される。 In this embodiment, the drain port 23 is provided at the outer peripheral portion of the inner tank bottom 102. When the inner tub 1 is in the fixed drainage position, the drainage port 23 rotates right below the axis of the inner tub 1. The water collecting tank 30 includes a concave tank provided below the drain port 23. The rear side wall of the recessed tank extends vertically upward to the rear side of the drainage port 23 and is spaced apart from the drainage port 23 by a certain distance. As a result, the water flow that has flowed out from the drain port 23 is guided to fall into the water collecting tank 30, so that the situation in which the drain water that has flowed backward from the horizontally provided drain port is scattered outside the washing machine is avoided. .. In addition, the front side wall of the water collecting tub 30 and the lower part of the inner tub 1 of the washing machine are in close contact with each other or separated by an extremely small distance. As a result, the water in the water collection tank 30 does not scatter from the front end, and the situation in which the drainage water from the inner tank overflows is avoided.
本実施例において、前記集水槽30は洗濯機の内槽支持部材3に装着されるか、内槽支持部材3と一体的に成型され、バルブコア開放機構が集水槽30に装着される。 In this embodiment, the water collecting tank 30 is mounted on the inner tank supporting member 3 of the washing machine or is integrally molded with the inner tank supporting member 3, and the valve core opening mechanism is mounted on the water collecting tank 30.
本実施例において、位置決めロック機構は、洗濯機の内槽を固定排水位置まで回転させて固定するよう制御可能な従来の任意の機構とすればよい。例えば、内槽を回転駆動させる駆動モータに対応した制御プログラムを設けることで、内槽を固定排水位置まで回転させてロックし、内槽をそれ以上回転させないよう制御する。また、位置決めロック機構を次のように設けてもよい。即ち、図2及び図3に示すように、内槽1の側壁に内側に凹陥するロック溝45を設けるとともに、ロック溝45に対応して設けられるロックピン44を洗濯機に装着する。前記ロックピン44は、内槽の径方向に伸縮可能に洗濯機のハウジング2又は内槽支持部材3に装着される。図2に示すように、ロックピン44は、駆動装置の働きによって内側に収縮する際に、ロック溝45から離脱することで内槽1を回転自在とする。また、図3に示すように、ロックピン44は駆動装置の働きによって外側に飛び出すと、内槽1のロック溝45に進入する。これにより、内槽1はそれ以上回転しなくなり、且つ、固定排水位置に配置されるため、排水口23がバルブコア開放機構に対応する位置に配置される。 In this embodiment, the positioning lock mechanism may be any conventional mechanism that can be controlled to rotate and fix the inner tub of the washing machine to the fixed drainage position. For example, by providing a control program corresponding to a drive motor that rotationally drives the inner tank, the inner tank is rotated to the fixed drainage position and locked, and the inner tank is controlled so as not to rotate any more. Further, the positioning lock mechanism may be provided as follows. That is, as shown in FIGS. 2 and 3, a lock groove 45 recessed inward is provided on the side wall of the inner tub 1, and a lock pin 44 provided corresponding to the lock groove 45 is attached to the washing machine. The lock pin 44 is attached to the housing 2 or the inner tub support member 3 of the washing machine so as to be expandable and contractible in the radial direction of the inner tub. As shown in FIG. 2, when the lock pin 44 contracts inward by the action of the drive device, the lock pin 44 separates from the lock groove 45, thereby allowing the inner tank 1 to rotate. Further, as shown in FIG. 3, when the lock pin 44 jumps out by the action of the driving device, it enters the lock groove 45 of the inner tank 1. As a result, the inner tub 1 does not rotate any more and is disposed at the fixed drainage position, so that the drainage port 23 is disposed at a position corresponding to the valve core opening mechanism.
図4に示すように、洗濯機の正常な洗浄過程では、排水弁が閉止されて内槽が正常に回転する。よって、内槽内に貯えられた水は、排水口から流出することなく衣類を正常に洗浄する。また、図5に示すように、洗濯機の排水過程では、内槽が固定排水位置まで回転し、ステッピングモータが回転ローラを回転させる。すると、回転ローラがコネクティングロッドを内槽方向に移動させ、コネクティングロッドの端部が対向位置における排水弁のバルブプラグを内槽の内部へと移動させる。すると、バルブプラグがバネの張力に抗して押し動かされ、排水口を開放するため、内槽内の水が開放された排水口から流出する。流出した水流は集水槽により収集されたあと、排水管から洗濯機の外部へと排出される。これにより、内槽内に貯えられた水を排出するとの目的が達せられる。 As shown in FIG. 4, in the normal washing process of the washing machine, the drain valve is closed and the inner tub rotates normally. Therefore, the water stored in the inner tank cleans the clothes normally without flowing out from the drain port. Further, as shown in FIG. 5, in the drainage process of the washing machine, the inner tub rotates to the fixed drainage position, and the stepping motor rotates the rotating roller. Then, the rotating roller moves the connecting rod toward the inner tank, and the end portion of the connecting rod moves the valve plug of the drain valve at the facing position into the inner tank. Then, the valve plug is pushed against the tension of the spring to open the drain port, so that the water in the inner tank flows out from the opened drain port. The water flow that flows out is collected by the water collection tank and then discharged from the drain pipe to the outside of the washing machine. As a result, the purpose of discharging the water stored in the inner tank is achieved.
本実施例は、実施例1と以下の点において異なる。即ち、前記バルブコア開放機構は、内槽支持部材3に装着される電磁石を含む。内槽1が固定排水位置まで回転したときに排水弁23と電磁石が同軸線方向に配置されるよう、前記電磁石は排水弁23に対応して設けられる。排水弁23のバルブコア25には磁石が装着されるか、バルブコア全体が磁石から構成される。これにより、電磁石の通電後にバルブコア25に電磁斥力が付与されて、バルブコア25が内槽1の内側方向へと押し動かされるため、排水弁23が開放されて排水がなされる。 This example is different from Example 1 in the following points. That is, the valve core opening mechanism includes an electromagnet mounted on the inner tank supporting member 3. The electromagnet is provided corresponding to the drain valve 23 so that the drain valve 23 and the electromagnet are arranged in the coaxial line direction when the inner tank 1 is rotated to the fixed drain position. A magnet is attached to the valve core 25 of the drain valve 23, or the entire valve core is made of a magnet. As a result, an electromagnetic repulsive force is applied to the valve core 25 after the electromagnet is energized, and the valve core 25 is pushed inward of the inner tank 1, so that the drain valve 23 is opened and drainage is performed.
洗濯機の正常な洗浄過程では、排水弁が閉止されて内槽が正常に回転する。よって、内槽内に貯えられた水は、排水口から流出することなく衣類を正常に洗浄する。また、洗濯機の排水過程では、内槽が固定排水位置まで回転するとともに、電磁石が通電する。すると、電磁石がバルブコアに斥力を付与することで、バルブコアが斥力の作用によってバネの弾性力に抗し、内槽の内部方向へと移動する。これにより、内槽の排水口が開放され、内槽内の水が開放された排水口から流出する。流出した水流は集水槽により収集されたあと、排水管から洗濯機の外部へと排出されるため、同様に内槽内に貯えられた水を排出するとの目的を実現可能である。 In the normal washing process of the washing machine, the drain valve is closed and the inner tub rotates normally. Therefore, the water stored in the inner tank cleans the clothes normally without flowing out from the drain port. Further, in the drainage process of the washing machine, the inner tub rotates to the fixed drainage position and the electromagnet is energized. Then, the electromagnet applies a repulsive force to the valve core, so that the valve core moves against the elastic force of the spring due to the action of the repulsive force, and moves toward the inside of the inner tank. As a result, the drainage port of the inner tank is opened, and the water in the inner tank flows out from the opened drainage port. The water flow that has flowed out is collected by the water collection tank and then discharged from the drain pipe to the outside of the washing machine. Therefore, it is possible to realize the purpose of discharging the water stored in the inner tank as well.
本実施例では、洗濯機の動作時に内槽槽口101の密封を実現するために、以下のように設置する。 In this embodiment, in order to realize the sealing of the inner tub opening 101 when the washing machine is operated, it is installed as follows.
図1に示すように、洗濯機は、洗濯機のハウジング2に扉4が装着されている。扉4は、弾性機構を介して相対的に回転可能に内槽蓋8に接続される。扉4が閉止されると、弾性機構が内槽蓋8に対しロック弾性力を付与することで、内槽蓋8と内槽槽口101が密封状に接触するとともに、内槽蓋8が内槽1に付随して回転するようになる。これにより、扉4の閉止後に内槽蓋8が内槽槽口101に掛合し、内槽1を密封するとの目的が実現される。 As shown in FIG. 1, in the washing machine, a door 4 is attached to a housing 2 of the washing machine. The door 4 is rotatably connected to the inner tank lid 8 via an elastic mechanism. When the door 4 is closed, the elastic mechanism applies a lock elastic force to the inner tank lid 8 so that the inner tank lid 8 and the inner tank lid 101 contact in a sealed manner, and the inner tank lid 8 is closed. It comes to rotate with the tank 1. This realizes the purpose that the inner tank lid 8 is engaged with the inner tank opening 101 after the door 4 is closed to seal the inner tank 1.
上記のように設けることで、弾性力で圧着する内槽蓋により内槽槽口の密封が実現される。洗濯機の洗浄過程では、内槽蓋が内槽槽口に密封状に接触するとともに、内槽に付随して回転する。これにより、内槽の回転時に槽口を動的に密封するとの目的が達せられるため、内槽に回転及び貯水という2つの機能を持たせられる。且つ、内槽の外部に外槽を嵌装する必要がなく、内槽の容積が大きくなるため、洗濯機の洗浄容量が増加する。 By providing as described above, the inner tank lid that is pressure-bonded by the elastic force realizes the sealing of the inner tank opening. During the washing process of the washing machine, the inner tub lid comes into sealing contact with the inner tub opening and rotates together with the inner tub. This achieves the purpose of dynamically sealing the tank opening when the inner tank rotates, so that the inner tank has two functions of rotation and water storage. Moreover, since it is not necessary to fit the outer tub outside the inner tub, and the volume of the inner tub is increased, the washing capacity of the washing machine is increased.
本実施例において、扉4と内槽蓋8は同軸に設けられる。扉4と内槽蓋8は弾性機構を介して接続されるため、扉4を閉止すると、内槽蓋8が圧縮状態の弾性機構の作用によって内槽槽口101に圧着する。 In this embodiment, the door 4 and the inner tank lid 8 are provided coaxially. Since the door 4 and the inner tank lid 8 are connected via the elastic mechanism, when the door 4 is closed, the inner tank lid 8 is pressed against the inner tank opening 101 by the action of the elastic mechanism in the compressed state.
本実施例において、内槽蓋8は扉4の開閉に伴って動作するよう扉4に固定接続されるため、内槽蓋8により内槽槽口101を開閉するとの目的が達せられる。且つ、洗濯機を閉止したあと、内槽蓋8と内槽1が密閉状に固定接続されるとともに、内槽蓋8が内槽1に付随して回転するよう、内槽蓋8と扉4は中心軸線周りに相対的に回転可能とする。 In the present embodiment, since the inner tank lid 8 is fixedly connected to the door 4 so as to operate with the opening and closing of the door 4, the purpose of opening and closing the inner tank lid 101 by the inner tank lid 8 can be achieved. Moreover, after the washing machine is closed, the inner tub lid 8 and the inner tub 1 are fixedly connected in a hermetically sealed manner, and the inner tub lid 8 and the door 4 are rotated so that the inner tub lid 8 rotates together with the inner tub 1. Is relatively rotatable about the central axis.
好ましくは、本実施例において、内槽蓋8の掛合後に内槽蓋8と内槽槽口101との密封性が強化されるよう、内槽蓋8と内槽槽口101を弾性的に係接してもよい。これにより、扉4を閉止すると、内槽蓋と内槽槽口101が固定的に係接される一方、扉4を開放すると、内槽蓋が扉4とともに移動して内槽槽口101から離脱する。従って、内槽蓋8と内槽槽口101との密封接触箇所を係接及び固定し、内槽槽口101の密封性を強化するとの目的が実現される。 Preferably, in this embodiment, the inner tank lid 8 and the inner tank lid 101 are elastically engaged so that the sealing performance between the inner tank lid 8 and the inner tank lid 101 is enhanced after the inner tank lid 8 is engaged. You may contact. Thereby, when the door 4 is closed, the inner tank lid and the inner tank opening 101 are fixedly engaged, while when the door 4 is opened, the inner tank lid moves together with the door 4 and the inner tank opening 101 moves away from the inner tank opening 101. break away. Therefore, the purpose of engaging and fixing the sealed contact portion between the inner tank lid 8 and the inner tank opening 101 to enhance the sealing property of the inner tank opening 101 is realized.
本実施例において、内槽蓋8の中心には、内槽1の軸線方向に沿って内槽の外部へと延伸する回転軸12が接続されており、内槽蓋8が回転軸周りに回転可能である。回転軸12は一端が内槽蓋8に回転可能に接続され、他端が弾性機構を介して扉4に接続される。弾性機構は内槽蓋8に弾性力を付与することで、内槽蓋8を内槽槽口101方向へと移動させる。これにより、内槽蓋8が内槽槽口101に密封状に掛合し、内槽槽口101の密封を実現する。 In the present embodiment, a rotary shaft 12 that extends to the outside of the inner tank along the axial direction of the inner tank 1 is connected to the center of the inner tank lid 8, and the inner tank lid 8 rotates around the rotation axis. It is possible. The rotating shaft 12 has one end rotatably connected to the inner tank lid 8 and the other end connected to the door 4 via an elastic mechanism. The elastic mechanism moves the inner tank lid 8 toward the inner tank opening 101 by applying an elastic force to the inner tank lid 8. As a result, the inner tank lid 8 is engaged with the inner tank opening 101 in a sealed manner, and the inner tank opening 101 is sealed.

Has been. The rotating shaft 12 extends in the axial direction of the inner tank 1, and the inner tank lid 8 is relatively rotatable around the rotating shaft 12. The end of the rotary shaft 12 is fixedly connected to the door 4 via the spring 9. Therefore, when the door 4 is closed, the spring 9 is brought into a compressed state to bring the inner tank lid 8 into sealing contact with the inner tank opening 101, and the inner tank lid 8 is relatively rotated around the rotation axis with respect to the door 4. It becomes rotatable. Preferably, the insertion end of the rotary shaft 12 that is inserted into the mounting tank 11 of the inner tank lid 8 is engaged with the mounting tank 11 of the inner tank lid 8 so that the rotary shaft 12 and the inner tank lid 8 are axially moved. A protruding portion that protrudes in the outer diameter direction is provided so as to be fixed.
本実施例では、バネによる圧着力及び内槽蓋の掛合後の安定性を高めるために、特に以下のように設置する。即ち、図1及び図2に示すように、内槽蓋8の外側の中心には、外側に突出するよう延伸する装着槽11が設けられており、装着槽11には、軸受を介して装着される回転軸12が設けられている。回転軸12は内槽1の軸線方向に延伸しており、内槽蓋8が回転軸12周りに相対的に回転可能である。また、回転軸12の端部には、回転軸12の軸線に対し垂直な支持プレート10が装着されており、支持プレート10の外周部が複数のバネ9を介して扉4に固定接続される。 In this embodiment, in order to enhance the pressure force of the spring and the stability of the inner tank lid after being engaged, the following installation is performed. That is, as shown in FIGS. 1 and 2, a mounting tank 11 is provided at the center of the outer side of the inner tank lid 8 so as to extend to the outside, and the mounting tank 11 is mounted via a bearing. The rotating shaft 12 is provided. The rotating shaft 12 extends in the axial direction of the inner tank 1, and the inner tank lid 8 is relatively rotatable around the rotating shaft 12. A support plate 10 perpendicular to the axis of the rotary shaft 12 is attached to the end of the rotary shaft 12, and the outer periphery of the support plate 10 is fixedly connected to the door 4 via a plurality of springs 9. ..
本実施例において、支持プレート10の直径は内槽槽口101の直径以上である。また、支持プレート10と内槽1は同軸に設けられる。各バネ9は、内槽1の軸線に対して対称に支持プレート10の外周部に配置される。また、各バネ9は、内槽1の軸線に対し平行な方向に設けられる。 In this embodiment, the diameter of the support plate 10 is larger than the diameter of the inner tank opening 101. Further, the support plate 10 and the inner tank 1 are provided coaxially. The springs 9 are arranged on the outer peripheral portion of the support plate 10 symmetrically with respect to the axis of the inner tank 1. Further, each spring 9 is provided in a direction parallel to the axis of the inner tank 1.
回転軸に接続される支持プレートを洗濯機の扉と内槽蓋との間に追加するとともに、外周に均一に配置される複数のバネを介して支持プレートを扉に接続することで、内槽蓋は複数方向の異なるバネによる位置規制の弾性力を受けることになる。これにより、内槽蓋は、安定的且つ傾斜することなく内槽槽口に密封状に接触するため、洗濯機における内槽槽口の密封の確実性が向上する。 By adding a support plate connected to the rotating shaft between the door of the washing machine and the inner tub lid, and connecting the support plate to the door via a plurality of springs evenly arranged on the outer circumference, The lid receives the elastic force of the position regulation by the springs in different directions. As a result, the inner tub lid is in stable contact with the inner tub tub in a sealing manner without tilting, so that the certainty of sealing the inner tub tub in the washing machine is improved.
バネが装着された回転軸を介して内槽蓋と扉を接続することで、扉が閉止されると、内槽蓋が内槽槽口に接触してバネを圧縮する。バネは内槽蓋に対し内槽方向に移動する弾性力を付与するため、内槽蓋は内槽槽口に密封状に密着する。これにより、扉の閉止後に内槽蓋を規制し、内槽蓋と内槽槽口を密封状に接触させるとの目的が実現される。且つ、内槽蓋と回転軸は相対的に回転可能なため、内槽が洗濯機の駆動モータにより回転する際に、内槽蓋は摩擦力の作用によって内槽とともに回転可能である。これにより、内槽槽口を密封処理するとの目的が実現される。更に、内槽の前端は、内槽蓋、回転軸、バネを介して扉に接続されるため、震動可能に弾性をもって洗濯機のハウジング内に装着される。これにより、内槽の前端と洗濯機のハウジングが互いに支持するよう装着されることから、内槽に対する支持の作用点が強化され、内槽の運転過程における安定性が向上する。 When the door is closed by connecting the inner tank lid and the door via the rotating shaft equipped with the spring, the inner tank lid comes into contact with the inner tank opening to compress the spring. Since the spring applies an elastic force to the inner tank lid so as to move in the inner tank direction, the inner tank lid tightly contacts the inner tank opening in a sealed manner. Thus, the purpose of regulating the inner tank lid after the door is closed and bringing the inner tank lid into contact with the inner tank opening in a sealed manner is realized. Moreover, since the inner tub lid and the rotating shaft are rotatable relative to each other, when the inner tub is rotated by the drive motor of the washing machine, the inner tub lid can be rotated together with the inner tub by the action of frictional force. This achieves the purpose of sealing the inner tank opening. Furthermore, since the front end of the inner tub is connected to the door via the inner tub lid, the rotary shaft, and the spring, it is elastically mounted in the housing of the washing machine. Accordingly, the front end of the inner tub and the housing of the washing machine are mounted so as to support each other, so that the action point of support for the inner tub is strengthened, and the stability of the inner tub in the operating process is improved.
本実施例において、回転軸12には同軸に設けられる給水管17が装着されている。給水管17は、一端が内槽蓋8を介して内槽1に挿入されるとともに、他端が回転軸12を貫通して上方へと屈曲し、洗濯機の給水構造と連通するまで延伸している。これにより、洗濯機に対する給水は、内槽槽口101の中心から内槽1へと流入するため、洗濯機の内槽1に対し前端の内槽蓋8の中心から給水するとの目的が実現される。好ましくは、内槽1の密封性を保証すべく、内槽蓋8と回転軸12とのヒンジ接続箇所が水封される。 In the present embodiment, a water supply pipe 17 provided coaxially is attached to the rotary shaft 12. The water supply pipe 17 has one end inserted into the inner tub 1 through the inner tub lid 8 and the other end penetrating the rotary shaft 12 and bent upward to extend until it communicates with the water supply structure of the washing machine. ing. As a result, water is supplied to the washing machine from the center of the inner tub opening 101 to the inner tub 1, so that the purpose of supplying water to the inner tub 1 of the washing machine from the center of the inner tub lid 8 at the front end is realized. It Preferably, the hinge connection point between the inner tank lid 8 and the rotary shaft 12 is water-sealed in order to ensure the hermeticity of the inner tank 1.
本実施例において、内槽蓋8の外周には外側に傾斜する傾斜部15が設けられている。前記傾斜部15は、内槽1の外周から扉4に向かって徐々に直径が大きくなるテーパー状面をなしている。また、内槽槽口101には、傾斜部15に対し密着状に接触する固定部16が設けられている。好ましくは、固定部16の外端に、外側へと屈曲する面取り部が設けられる。これにより、内槽蓋8が内槽槽口101内に滑り込むよう案内され、固定部16と傾斜部15が互いに密着することで密封が実現される。 In the present embodiment, an inclined portion 15 that is inclined outward is provided on the outer periphery of the inner tank lid 8.

The first tapered surface corresponds to the horizontally bent surface of the inner tank basin 101. The horizontal bent surface is a cylindrical surface that is bent horizontally from the inner tank 1 to the outside of the inner tank 1. The inner diameter of the horizontal curved surface is equal to or slightly smaller than the maximum diameter of the first tapered surface. The end of the horizontal curved surface is gradually inclined outward to form a taper-shaped fixing portion 16. In addition, the second tapered surface constitutes the inclined portion 15 and is in close contact with the fixed portion 16.
本実施例では、内槽蓋8と扉4の間に、径方向に伸縮可能な管状のシールパイプ14が更に設けられている。弾性機構がシールパイプ14の内部に密封状に装着され、シールパイプ14の伸縮に伴って内槽蓋8が扉4に対して相対的に移動するよう、シールパイプ14は一端が扉4の外周に密封接続され、他端が扉4に固定接続される。前記シールパイプ14は、弾性ゴム材質のコルゲートパイプから構成される。好ましくは、扉4が内槽1に付随して回転する際にシールパイプ14が共に回転しないよう、シールパイプ14の端部と扉4は、内槽1の軸線周りに相対的に回転可能に嵌接される。 In the present embodiment, a tubular seal pipe 14 that can expand and contract in the radial direction is further provided between the inner tank lid 8 and the door 4.

本実施例では、洗濯機の内槽内の衣類から離脱した水流を排出するとともに、洗濯機の動作過程では、内槽を密封して貯水することで正常な洗浄を行うべく、以下のように設置する。 In this embodiment, the water flow separated from the clothes in the inner tub of the washing machine is discharged, and in the process of operation of the washing machine, the inner tub is sealed to store water in order to perform normal washing as follows. Install.
図1に示すように、洗濯機の脱水構造において、洗濯機のハウジング2の内部には内槽1が装着されている。内槽1は、一端の直径が小さく、一端の直径が大きなテーパー状の槽であり、内槽1の大径端に脱水流路36が設けられている。脱水流路36は、一端が内槽1の大径端に連通するとともに、他端が大径端の中心を経由して内槽1を貫通し、洗濯機の排水管31に連通している。 As shown in FIG. 1, in a dehydrating structure of a washing machine, an inner tub 1 is mounted inside a housing 2 of the washing machine. The inner tank 1 is a tapered tank having a small diameter at one end and a large diameter at one end, and a dehydration flow path 36 is provided at the large-diameter end of the inner tank 1. The dehydration flow path 36 has one end communicating with the large diameter end of the inner tub 1, and the other end penetrating the inner tub 1 via the center of the large diameter end and communicating with the drain pipe 31 of the washing machine. ..
本発明の実施例では、洗濯機の脱水方法について更に説明する。内槽が一定の回転速度で回転することで、内槽内の衣類から離脱した洗浄水は、遠心力の作用でテーパー状の内槽の内壁に密着しつつ、大径端に向かって流動する。水流は、内槽の大径端に到達すると、大径端に設けられた脱水流路に沿って内槽の大径端の中心から流出し、排水管に沿って洗濯機から流出する。これにより、内槽内の洗浄水の排出が実現される。 In the embodiment of the present invention, a method for dehydrating a washing machine will be further described. When the inner tank rotates at a constant rotation speed, the wash water separated from the clothes in the inner tank flows toward the large diameter end while being brought into close contact with the inner wall of the tapered inner tank by the action of centrifugal force. .. When the water flow reaches the large-diameter end of the inner tub, it flows out from the center of the large-diameter end of the inner tub along the dewatering flow path provided at the large-diameter end, and flows out of the washing machine along the drain pipe. As a result, the cleaning water in the inner tank is discharged.
ドラム洗濯機の正常な洗浄過程において、内槽1は一般的に低速で回転するため、内槽1内の水はあまり遠心力の作用を受けない。よって、内槽1内の衣類と水流が内槽の低速回転に伴い打ち付け合うことで、洗浄効果が奏される。且つ、内槽1内の水流は、大径端に集まるよう流動することも、洗濯機から排出されることもない。一方、ドラム洗濯機の脱水過程において、内槽1は中高速で回転するため、内槽1内の衣類から離脱した水は内槽の回転に伴う遠心力の作用を受ける。これにより、内槽1内の水流は、内槽壁に密着しつつ内槽の大径端に集まるよう流動する。そして、内槽の大径端に設けられた脱水流路36に流入し、内槽1の大径端の中心を経由して内槽1から流出するとともに、排水管31を通じて洗濯機から排出される。 In the normal washing process of the drum washing machine, the inner tub 1 generally rotates at a low speed, so that the water in the inner tub 1 is not much affected by centrifugal force. Therefore, the clothes in the inner tub 1 and the water flow strike against each other as the inner tub rotates at a low speed, so that a cleaning effect is achieved. Moreover, the water flow in the inner tub 1 does not flow so as to collect at the large diameter end and is not discharged from the washing machine. On the other hand, in the dehydration process of the drum washing machine, since the inner tub 1 rotates at medium and high speeds, the water separated from the clothes in the inner tub 1 is subjected to the centrifugal force caused by the rotation of the inner tub. As a result, the water flow in the inner tank 1 flows so as to come into close contact with the inner tank wall and collect at the large diameter end of the inner tank. Then, it flows into the dehydration flow path 36 provided at the large diameter end of the inner tub, flows out of the inner tub 1 via the center of the large diameter end of the inner tub 1, and is discharged from the washing machine through the drain pipe 31. It
上記のように設けることで、洗濯機の正常な洗浄状態では、内槽内の水流が遠心力の作用を受けず、内槽の大径端に集まるよう流動することがない。一方、洗濯機の脱水状態では、内槽が高速回転するため、内槽内の水流が遠心力の作用を受けて内槽の大径端における脱水流路に向かって流動し、排出される。よって、内槽の正常な回転時に内槽内に貯えられた水が排水口から流出することはない。これにより、内槽の回転過程では内槽を密封し、排水時には、排水弁を開放することで内槽内の衣類から離脱した水を正常に排出するとの効果が実現される。従って、内槽の回転及び貯水という2つの効果を有する洗濯機による正常な脱水との目的が達せられる。且つ、内槽の外部に外槽を嵌装する必要がなく、内槽の容積が大きくなるため、洗濯機の洗浄容量が増加する。 By providing as described above, in a normal washing state of the washing machine, the water flow in the inner tub is not subjected to the action of centrifugal force and does not flow to collect at the large diameter end of the inner tub. On the other hand, when the washing machine is in a dehydrated state, the inner tub rotates at a high speed, so that the water flow in the inner tub is subjected to the action of centrifugal force to flow toward the dehydration flow path at the large diameter end of the inner tub and is discharged. Therefore, the water stored in the inner tank does not flow out from the drainage port when the inner tank normally rotates. As a result, the effect that the inner tank is sealed during the rotation process of the inner tank and the drain valve is opened at the time of draining to normally discharge the water separated from the clothes in the inner tank is realized. Therefore, the purpose of normal dehydration by the washing machine having two effects of rotation of the inner tub and storage of water can be achieved. Moreover, since it is not necessary to fit the outer tub outside the inner tub, and the volume of the inner tub is increased, the washing capacity of the washing machine is increased.
本実施例において、内槽1は、前端が内槽槽口101であり、後端が内槽底102である。内槽槽口101と内槽底102は内槽の側壁を介して接続される。内槽の側壁は、テーパー状の内槽1を構成するよう、内槽槽口101から内槽底102に向かって徐々に直径が拡大するテーパー状をなしている。内槽底102の中心は、回転軸を介して内槽支持部材3に装着される。脱水流路36は、内槽底102の内側面に設けられる。脱水流路36は、一端が内槽底102と内槽の側壁との交差箇所に設けられ、他端が内槽底102の中心を貫通して軸線沿いにモータ軸に挿通される。また、脱水流路36の挿通端は洗濯機の排水管31と連通する。 In this embodiment, the inner tank 1 has an inner tank opening 101 at the front end and an inner tank bottom 102 at the rear end. The inner tank opening 101 and the inner tank bottom 102 are connected via the side wall of the inner tank. The side wall of the inner tank is tapered so that the diameter of the inner tank gradually increases from the inner tank opening 101 toward the inner tank bottom 102 so as to form the tapered inner tank 1. The center of the inner tank bottom 102 is attached to the inner tank supporting member 3 via a rotary shaft. The dehydration channel 36 is provided on the inner side surface of the inner tank bottom 102. The dehydration flow path 36 has one end provided at the intersection of the inner tank bottom 102 and the side wall of the inner tank, and the other end penetrates the center of the inner tank bottom 102 and is inserted into the motor shaft along the axis. Further, the insertion end of the dehydration flow path 36 communicates with the drain pipe 31 of the washing machine.
本実施例において、内槽底102には複数の脱水流路36が設けられている。各脱水流路36の一端は、等しい角度を隔てて内槽底102の外周に均一に配置されるとともに、内槽1の内部と連通する。また、他端は内槽底102の中心と交差するとともに、内槽底102の中心を貫通して洗濯機の排水管31に連通する。 In this embodiment, the inner tank bottom 102 is provided with a plurality of dehydration flow paths 36. One end of each dehydration flow path 36 is evenly arranged on the outer periphery of the inner tank bottom 102 at equal angles and communicates with the inside of the inner tank 1. The other end intersects the center of the inner tub bottom 102 and penetrates the center of the inner tub bottom 102 to communicate with the drain pipe 31 of the washing machine.
本実施例において、少なくとも1つの脱水流路36は、一端が内槽底102の中央部に設けられて内槽1の内部と連通し、他端が内槽底102の中心を貫通して洗濯機の排水管31と連通する。好ましくは、隣接する脱水流路36の端部は、内槽底102の中央部又は外周部に互い違いに設けられる。内槽底の各部分における水流を吸着して排出するよう、内槽底には、端部が中央部又は外周部にそれぞれ設けられる均一に配置された複数の脱水流路が設けられるため、内槽内の水流の脱水効率が向上する。 In the present embodiment, at least one dewatering flow path 36 has one end provided at the center of the inner tub bottom 102 and communicating with the inside of the inner tub 1, and the other end penetrating the center of the inner tub bottom 102 to wash. It communicates with the drainage pipe 31 of the machine. Preferably, the end portions of the adjacent dewatering flow paths 36 are provided alternately in the central portion or the outer peripheral portion of the inner tank bottom 102. In order to adsorb and discharge the water flow in each part of the inner tank bottom, the inner tank bottom is provided with a plurality of evenly arranged dewatering flow paths whose end portions are respectively provided in the central portion or the outer peripheral portion. The dehydration efficiency of the water flow in the tank is improved.
本実施例において、各脱水流路36は、内槽底102の内側面から突出する中空の突出リブから構成される。内槽1の回転過程では、中空の突出リブが内槽1内の水流及び衣類を持ち上げ、打ち付けることで衣類を洗浄する。そのため、内側に突出する脱水流路36は、内槽1内の衣類を持ち上げ、打ち付けることで洗浄するという補助的リフティングリブ機能を有する。 In the present embodiment, each dehydration flow path 36 is composed of a hollow protruding rib protruding from the inner side surface of the inner tank bottom 102. In the process of rotating the inner tub 1, the hollow protruding ribs lift and hit the water flow and the clothes in the inner tub 1 to wash the clothes. Therefore, the dehydration flow path 36 protruding inward has an auxiliary lifting rib function of washing clothes in the inner tank 1 by lifting and hitting them.
本実施例では、洗濯機の内槽底102に流れ込んだ水流に圧力を付与することで、脱水流路36及び排水管31に沿って洗濯機の外部へ排水すべく、前記脱水流路36及び/又は排水管31に排水ポンプ33が設けられている。排水ポンプ33は、ドラム洗濯機の正常な洗浄状態では動作せず、ドラム洗濯機の脱水プログラム実行中に起動する。これにより、洗濯機の内槽からの水流排出を制御するとともに、水流に駆動力を付与可能となる。 In the present embodiment, by applying pressure to the water flow that has flowed into the inner tub bottom 102 of the washing machine, the water is drained to the outside of the washing machine along the dehydration channel 36 and the drain pipe 31. A drainage pump 33 is provided on the drainage pipe 31. The drainage pump 33 does not operate in a normal washing state of the drum washing machine and is activated during execution of the dehydration program of the drum washing machine. This makes it possible to control the discharge of the water flow from the inner tub of the washing machine and to apply a driving force to the water flow.
本実施例では、上記実施例4で記載した洗濯機に基づく脱水方法について説明する。内槽が一定の回転速度で回転することで、内槽内の洗浄水が遠心力の作用でテーパー状の内槽の内壁に密着しつつ、大径端に向かって流動する。水流は、内槽の大径端に到達すると、大径端に設けられた脱水流路に沿って内槽の大径端の中心から流出し、排水管に沿って洗濯機から流出する。これにより、内槽内の洗浄水の排出が実現される。 In this embodiment, a dewatering method based on the washing machine described in the fourth embodiment will be described. By rotating the inner tank at a constant rotation speed, the washing water in the inner tank flows toward the large diameter end while being brought into close contact with the inner wall of the tapered inner tank by the action of centrifugal force. When the water flow reaches the large-diameter end of the inner tub, it flows out from the center of the large-diameter end of the inner tub along the dewatering flow path provided at the large-diameter end, and flows out of the washing machine along the drain pipe. As a result, the cleaning water in the inner tank is discharged.
上記の方法によれば、洗濯機の正常な洗浄状態では、内槽内の水流が遠心力の作用を受けず、内槽の大径端に集まるよう流動することがない。一方、洗濯機の脱水状態では内槽が高速回転するため、内槽内の水流が遠心力の作用を受けて内槽の大径端における脱水流路に向かって流動し、排出される。よって、内槽の正常な回転時に内槽内に貯えられた水が脱水口から流出することはない。これにより、内槽の回転過程では内槽を密封し、脱水時には、脱水弁を開放することで内槽内に貯えられた水を正常に排出するとの効果が実現される。従って、内槽の回転及び貯水という2つの効果を有する洗濯機による正常な脱水との目的が達せられる。 According to the above method, in a normal washing state of the washing machine, the water flow in the inner tub is not subjected to the action of the centrifugal force and does not flow to collect at the large diameter end of the inner tub. On the other hand, in the dehydrated state of the washing machine, the inner tub rotates at a high speed, so that the water flow in the inner tub is subjected to the action of centrifugal force to flow toward the dehydration flow path at the large diameter end of the inner tub and is discharged. Therefore, the water stored in the inner tank does not flow out from the dehydration port when the inner tank normally rotates. As a result, the effect that the water stored in the inner tank is normally discharged by sealing the inner tank during the rotation process of the inner tank and opening the dehydration valve at the time of dehydration is realized. Therefore, the purpose of normal dehydration by the washing machine having two effects of rotation of the inner tub and storage of water can be achieved.
本実施例において、前記洗濯機の脱水方法の具体的ステップは次の通りである。 In this embodiment, the concrete steps of the washing machine dehydration method are as follows.
ステップ1:洗濯機の内槽が一定の回転速度で回転することで、内槽内の水流が遠心力の作用により内槽の側壁と密着するまで流動する。 Step 1: The inner tub of the washing machine rotates at a constant rotation speed, and the water flow in the inner tub flows until it comes into close contact with the side wall of the inner tub by the action of centrifugal force.
ステップ2:テーパー状の内槽の作用によって、内槽の側壁に密着した水流が内槽の側壁により案内されるとともに、内槽の回転過程における遠心力の作用を受けて、内槽内の水流が大径の内槽底へと向かう。 Step 2: Due to the action of the tapered inner tank, the water flow closely attached to the side wall of the inner tank is guided by the side wall of the inner tank, and the water flow in the inner tank is affected by the centrifugal force in the rotating process of the inner tank. Heads towards the bottom of the large diameter inner tank.
ステップ3:内槽底まで流動した水流が内槽底に設けられた脱水流路に流入し、脱水流路に沿って内槽の中心経由で内槽から流出するとともに、排水管に沿って洗濯機から排出される。 Step 3: The water flow that has flowed to the bottom of the inner tub flows into the dehydration channel provided at the bottom of the inner tub, flows out from the inner tub along the dehydration channel via the center of the inner tub, and is washed along the drain pipe. Discharged from the machine.
本実施例では、上記ステップ3において、脱水流路及び/又は排水管の排水ポンプが動作を開始することで、内槽底まで流動した水流に圧力が付与されるため、水が脱水流路及び排水管に沿って流動し、洗濯機の外部に排出される。また、洗濯機がその他のプログラムを実行する場合、脱水流路及び/又は排水管の排水ポンプは動作しないため、内槽内の水が排水ポンプの吸引により排出されることはない。よって、内槽内に水が保持されて、衣類を正常に洗浄する。 In the present embodiment, in step 3 above, the drainage pump of the dehydration flow channel and/or the drainage pipe starts operating, so that pressure is applied to the water flow that has flowed to the bottom of the inner tank. It flows along the drain pipe and is discharged to the outside of the washing machine. Further, when the washing machine executes other programs, the drainage pump of the dehydration flow path and/or the drainage pipe does not operate, so that the water in the inner tub is not discharged by suction of the drainage pump. Therefore, the water is retained in the inner tank and the clothes are washed normally.
本実施例では、洗濯機の脱水過程において、内槽が中高速で回転するため、内槽内の水が遠心力の作用によって内槽の側壁に密着しつつ、内槽の大径端に向かって流動する。 In the present embodiment, in the dehydration process of the washing machine, since the inner tub rotates at medium and high speeds, the water in the inner tub is closely attached to the side wall of the inner tub by the action of the centrifugal force and is directed toward the large diameter end of the inner tub. Flow.
