ドラム式洗濯機は、水平又は傾斜して配置された外槽内で、回転ドラムをモータで軸回転させて、洗濯物を洗濯,すすぎ,脱水まで行うことができるものであり、さらに乾燥機を内蔵させることにより連続して洗濯物の乾燥まで行うことができる。   A drum-type washing machine can perform washing, rinsing, and dehydration of a laundry by rotating a rotating drum with a motor in a horizontal or inclined outer tub. By incorporating it, the laundry can be continuously dried.

ドラム式洗濯機の前面側には、回転ドラムの内部から洗濯物を出し入れする際に開閉する蓋体が設けられている。   On the front side of the drum type washing machine, there is provided a lid that opens and closes when the laundry is taken in and out of the rotary drum.

そして、この開閉式の蓋体と洗濯機本体の開口部との間には、ベローズと称するゴムなどの柔軟なシール材が配置され、蓋体を閉じた状態にすると、このベローズにより封止され水漏れが防止される。   A flexible sealing material such as rubber called a bellows is disposed between the openable lid and the opening of the washing machine body. When the lid is closed, the lid is sealed with the bellows. Water leakage is prevented.

洗濯から乾燥までを連続して行う洗濯乾燥機による洗濯物の乾燥は、送風ファン及びヒータによって高温,低湿度の空気(温風)を生成して洗濯物が収容されたドラム内部へ供給し、洗濯物の温度を高くして洗濯物に含まれる水分を蒸発させ、蒸発した水分を機外へ排出することによって行われる。   Drying of the laundry by the washing and drying machine that continuously performs from washing to drying generates high-temperature and low-humidity air (warm air) by a blower fan and a heater, and supplies the air inside the drum in which the laundry is accommodated. This is done by elevating the temperature of the laundry to evaporate the moisture contained in the laundry and discharging the evaporated moisture out of the machine.

以下、本発明に係るドラム式洗濯機の実施形態について、図1から図7を参照して説明する。     Hereinafter, an embodiment of a drum type washing machine according to the present invention will be described with reference to FIGS. 1 to 7.

ドラム式洗濯機1は、図1に示す通り、前面側の正面パネル10に洗濯物14を出し入れする開口部6が形成され、この開口部6と連通し洗浄水の保持又は排出が自在に構成される外槽4と、この外槽4の内部において軸回転する洗濯槽としての回転ドラム5と、開口部6を開閉する蓋体7と、この蓋体7を開くときに押動する押ボタン16と、開口部6と蓋体7の縁部が接触した状態で蓋体7を保持するロック手段15と、前記ロック手段15により前記蓋体7が閉止するのを妨げる閉止抑制部8とを備える。   As shown in FIG. 1, the drum-type washing machine 1 is formed with an opening 6 through which the laundry 14 is put in and out of the front panel 10 on the front side, and is configured to communicate with the opening 6 and to freely hold or discharge the washing water. The outer tub 4, the rotating drum 5 serving as a washing tub that rotates in the outer tub 4, a lid 7 that opens and closes the opening 6, and a push button that is pushed when the lid 7 is opened. 16, a lock unit 15 that holds the lid 7 in a state where the opening 6 and the edge of the lid 7 are in contact with each other, and a closing suppression unit 8 that prevents the lid 7 from being closed by the locking unit 15. Prepare.

ドラム式洗濯機1は、その他、洗濯水を外槽4に供給する給水手段(図示略)と、洗剤を供給するために洗剤ボックス12と、乾燥工程において洗濯物14から離脱した繊維くずであるリントを捕捉する乾燥フィルタ17と、洗濯開始ボタンなどの操作ボタンが配置される操作パネル11とが配置されている。   The drum-type washing machine 1 is a water supply means (not shown) for supplying washing water to the outer tub 4, a detergent box 12 for supplying detergent, and fiber waste detached from the laundry 14 in the drying process. A drying filter 17 that captures lint and an operation panel 11 on which operation buttons such as a washing start button are arranged are arranged.

外槽4は、正面パネル10の側に開口を有する有底円筒形状でありその中心軸がベース3の水平面に対し傾斜するようにサスペンション2によって弾性的に支持されている。   The outer tub 4 has a bottomed cylindrical shape having an opening on the front panel 10 side, and is elastically supported by the suspension 2 so that the central axis thereof is inclined with respect to the horizontal plane of the base 3.

回転ドラム5は、正面パネル10の側に開口を有し、外槽4の内側に同軸に回動自在に軸支され、外槽4の背面に設けられた駆動モータ(図示せず)の駆動力によって回転する。   The rotary drum 5 has an opening on the front panel 10 side, is rotatably supported coaxially inside the outer tub 4, and is driven by a drive motor (not shown) provided on the back surface of the outer tub 4. Rotate by force.

サスペンション2は、ばねによる弾性力と例えば封入したオイル等による減衰力とを利用して、回転ドラム5の回転時の振動を低減する機能を備える。   The suspension 2 has a function of reducing vibration during rotation of the rotating drum 5 by using an elastic force of a spring and a damping force of, for example, enclosed oil.

乾燥手段は、乾燥時に作動することで、洗濯物14を乾燥する手段であって、ファン18と、ヒータ25と、除湿器20とを備えている。ファン18及びヒータ25は、外槽4の上に配置されている。除湿器20は、外槽4の底壁の外側で、モータ(図示せず)とずれた位置に配置されている。なお、除湿器20は、水道水等の低温流体が通流する冷却管20aを備えている。   The drying means is a means for drying the laundry 14 by operating during drying, and includes a fan 18, a heater 25, and a dehumidifier 20. The fan 18 and the heater 25 are disposed on the outer tub 4. The dehumidifier 20 is disposed outside the bottom wall of the outer tub 4 at a position shifted from a motor (not shown). The dehumidifier 20 includes a cooling pipe 20a through which a low-temperature fluid such as tap water flows.

そして、乾燥時に、ファン18,ヒータ25及び除湿器20が作動すると、ファン18からの空気が、ヒータ25で暖められた後、外槽4の通気孔4aを介して、回転ドラム5内に送り込まれるようになっている。次いで、この空気は、回転ドラム5から、外槽4の通気孔4bを介して、除湿器20に送り込まれ、除湿器20で除湿された後、ファン18に戻り、循環するようになっている。   When the fan 18, the heater 25, and the dehumidifier 20 are activated during drying, the air from the fan 18 is heated by the heater 25 and then sent into the rotating drum 5 through the vent hole 4 a of the outer tub 4. It is supposed to be. Next, the air is sent from the rotating drum 5 to the dehumidifier 20 through the vent hole 4b of the outer tub 4, and after dehumidifying by the dehumidifier 20, returns to the fan 18 and circulates. .

蓋体7は、開口部6を開閉するように軸支されるものであって、図1の実線で示される閉止状態から矢印方向に開いて破線で示される開放状態に設定してから洗濯物14の出し入れを行う。この蓋体7を開閉させる軸支部分には、図示しないスプリングが設けられ、蓋体7を開いて開放状態にする方向に力を付与している。そして、蓋体7が所定の角度以上の開放状態にある場合は、スプリングの力により更に開く方向へ蓋体7が付勢され、蓋体7が所定の角度以下の開放状態にある場合は、蓋体7の自重により閉じる方向へ蓋体7が付勢される構成となっている。   The lid 7 is pivotally supported so as to open and close the opening 6, and is opened in the direction of the arrow from the closed state shown by the solid line in FIG. 14 in and out. A spring (not shown) is provided on a shaft support portion that opens and closes the lid body 7, and applies a force in a direction to open the lid body 7 to open the lid body 7. When the lid body 7 is in an open state at a predetermined angle or more, the lid body 7 is urged further in the opening direction by the force of the spring, and when the lid body 7 is in an open state at a predetermined angle or less, The cover body 7 is configured to be biased in the closing direction by the weight of the cover body 7.

蓋体7は、閉止状態において、開口部6に配置されてシール機能を有するベローズ9(シール部材;図4参照)を挟み、外槽4の内部を水密にする機能を有する。   In the closed state, the lid body 7 has a function of sealing the bellows 9 (seal member; see FIG. 4) disposed in the opening 6 and having a sealing function to make the inside of the outer tub 4 watertight.

ロック手段15は、蓋体7が開いて開放状態にならないように水密な閉止状態を保持するものであって、押ボタン16の押動動作に連動して、この閉止状態の保持及び解除の切り替えを実行する。   The lock means 15 holds the watertight closed state so that the lid body 7 is not opened to be opened, and is switched between holding and releasing the closed state in conjunction with the pushing operation of the push button 16. Execute.

ロック手段15の保持機能を解除してから、蓋体7を開いて開放状態にし、開口部6から洗濯物14を回転ドラム5の内部に投入したり、洗濯・乾燥が終了した洗濯物14を取り出したりする。なお、ロック手段15の保持機能を解除すると、蓋体7を軸支するヒンジ部(図示せず)の反発力で破線部の位置にこの蓋体7を移動させる力が働く。   After releasing the holding function of the locking means 15, the lid body 7 is opened and opened, and the laundry 14 is put into the rotary drum 5 through the opening 6, or the laundry 14 that has been washed and dried is removed. Or take it out. When the holding function of the lock means 15 is released, a force for moving the lid body 7 to the position of the broken line portion is applied by a repulsive force of a hinge portion (not shown) that pivotally supports the lid body 7.

ここで、ロック手段15は、図8に示す通り、操作レバー31と、この操作レバー31に連動して蓋体7にも受けられたラッチ部32との間で係止または開放する動作を行う係止レバー33と、この係止レバー33が移動する方向に押圧するスプリング34を備えている。操作レバー31には、接続部31aを介して、押ボタン16(図1参照)の押動動作に連動して動く接続ロッド19の先端が接続されている。   Here, as shown in FIG. 8, the lock unit 15 performs an operation of locking or releasing between the operation lever 31 and the latch portion 32 received by the lid body 7 in conjunction with the operation lever 31. A locking lever 33 and a spring 34 that presses the locking lever 33 in the moving direction are provided. Connected to the operating lever 31 is a tip of a connecting rod 19 that moves in conjunction with a pushing operation of the push button 16 (see FIG. 1) via a connecting portion 31a.

係止レバー33にも受けられたピン39が、操作レバー31に設けられた傾斜40とスライド自在に接している。これにより、押ボタン16の押動動作に連動して接続ロッド19が上下動すると、係止レバー33が蓋体7のラッチ部32を係止(図8(a))または開放(図8(b))するように移動して、閉止状態の保持及び解除の切り替えを実行することになる。   A pin 39 received also by the locking lever 33 is in slidable contact with an inclination 40 provided on the operation lever 31. As a result, when the connecting rod 19 moves up and down in conjunction with the pushing operation of the push button 16, the locking lever 33 locks the latch portion 32 of the lid 7 (FIG. 8A) or opens (FIG. 8 (FIG. 8). b)), and the switching between holding and releasing the closed state is executed.

更に、本発明のラッチ部32は、図1に示す通り、蓋体7の内側(蓋体7を閉じたとき回転ドラム5側に位置する側)であって、図示しないヒンジ部と略同じ高さに設けられている。ここで、ラッチ部32は、ヒンジ部の回転軸が位置する部分に対して、蓋体7の中央部を挟んで略対称の位置に設けられているため、蓋体7をより確実にかつ安定的に閉止状態とすることができる。   Further, as shown in FIG. 1, the latch portion 32 of the present invention is on the inner side of the lid body 7 (the side located on the rotating drum 5 side when the lid body 7 is closed), and is substantially the same height as a hinge portion (not shown). Is provided. Here, since the latch part 32 is provided in the substantially symmetrical position on both sides of the center part of the cover body 7 with respect to the part in which the rotating shaft of a hinge part is located, the cover body 7 is more reliable and stable. Therefore, it can be in a closed state.

また、このラッチ部32は、図5に示す通り、蓋体7に取り付けられる開閉調整ベース21として、閉止抑制部8及び穴26と一体的に形成されている。そして、開閉調整ベース21の表面のうち、ラッチ部32及び開閉抑制部8を除く部分を、ステンレス鋼などで形成された蓋裏板24が覆い、蓋体7の内側の縁部にネジ等で取り付けられている(図2参照)。   Further, as shown in FIG. 5, the latch portion 32 is integrally formed with the closing suppression portion 8 and the hole 26 as the opening / closing adjustment base 21 attached to the lid body 7. A portion of the surface of the opening / closing adjustment base 21 excluding the latch portion 32 and the opening / closing suppression portion 8 is covered with a lid backing plate 24 formed of stainless steel or the like, and an inner edge portion of the lid body 7 is covered with a screw or the like. It is attached (see FIG. 2).

次に、蓋体7の縁部と開口部6との対向面の一部に設けられ、洗濯機の不使用時に隆起させる閉止抑制部8の構成の詳細について、図5〜図7を用いて説明する。この閉止抑制部8は、開閉調整ベース21の一端側に設けられた係合穴に対して、スプリング22を挟んでネジ23で締結されている。更に、この係合穴の外周側には、螺旋状溝28が開口部方向に彫られており、この螺旋状溝28に対して閉止抑制部8の凸部8aが回転摺動することで、閉止抑制部8は、開口部方向へ浮き上がる。そして、図7で示す開閉調整ベース21の凹形状21aに閉止抑制部8の凸部8aを嵌め込むことにより、回転軸方向の荷重に対して固定される。   Next, with reference to FIGS. 5 to 7, the details of the configuration of the closing suppression portion 8 that is provided on a part of the facing surface between the edge portion of the lid body 7 and the opening portion 6 and is raised when the washing machine is not used. explain. The closing suppression portion 8 is fastened to the engagement hole provided on one end side of the opening / closing adjustment base 21 with a screw 23 with a spring 22 interposed therebetween. Furthermore, on the outer peripheral side of the engagement hole, a spiral groove 28 is carved in the direction of the opening, and the convex portion 8a of the closing suppression portion 8 rotates and slides with respect to the spiral groove 28. The closing suppression unit 8 floats in the direction of the opening. Then, by fitting the convex portion 8a of the closing suppression portion 8 into the concave shape 21a of the opening / closing adjustment base 21 shown in FIG.

このように、閉止抑制部8が固定されることで、蓋体7がロック手段15により閉止状態で保持されるのを防ぐことが可能となる。尚、閉止抑制部8と開閉調整ベース21に挟まれたスプリング22は、初期時は開放状態(図6(a))であるのに対し、閉止抑制時(固定時)は閉止抑制部材8の軸方向へ収縮する(図6(b)参照)。また、閉止抑制部8やラッチ部32などで構成される開閉調整ベース21は、POM(ポリアセタール)樹脂を用いて形成されているので、摺動に対して強い。   Thus, by fixing the closing suppression portion 8, it is possible to prevent the lid body 7 from being held in the closed state by the locking means 15. The spring 22 sandwiched between the closing suppression portion 8 and the opening / closing adjustment base 21 is in an open state (FIG. 6A) at the initial stage, whereas the closing suppression member 8 is in a closed state (when fixed). Shrink in the axial direction (see FIG. 6B). In addition, the opening / closing adjustment base 21 including the closing suppression portion 8 and the latch portion 32 is formed using POM (polyacetal) resin, and thus is resistant to sliding.

図7の(a)〜(d)は、閉止抑制部8の開閉動作の流れを示している。(a)は初期状態であり、(a)状態時は蓋体7を閉止状態とすることが可能である。(d)は閉止抑制状態を示しており、(d)状態ではロック手段15によって蓋体7が閉止されることはない。このときの回転角は操作性と操作力と考慮し、140°としている。また(b),(c)は閉止抑制部8をそれぞれ45°、90°回転摺動させた状態を示しているが、(b),(c)状態で閉止抑制部8を開放した場合は、設けられたスプリング22の弾性力によって(a)状態に戻されることで、部材の誤使用を防ぐ構造となっている。   (A)-(d) of FIG. 7 has shown the flow of the opening / closing operation | movement of the closing suppression part 8. FIG. (A) is an initial state, and the lid body 7 can be closed in the state (a). (D) has shown the closing suppression state, and the lid 7 is not closed by the locking means 15 in the (d) state. The rotation angle at this time is 140 ° in consideration of operability and operation force. Moreover, (b) and (c) show the state in which the closing suppression unit 8 is rotated and rotated by 45 ° and 90 °, respectively, but when the closing suppression unit 8 is opened in the (b) and (c) states, By returning to the state (a) by the elastic force of the provided spring 22, the member is prevented from being misused.

尚、閉止抑制部8の固定を解除する際は、閉止抑制部材8の凸部8aが受け部の凹形状21aを乗り越えるだけの力を、右もしくは左のどちらか回転方向に対して加えることで、閉止抑制部8の軸方向(開放方向)にスプリング22の弾性力が働き、初期の位置(図7(a))に戻る。   In addition, when releasing the fixation of the closing suppression portion 8, a force sufficient for the convex portion 8 a of the closing suppression member 8 to overcome the concave shape 21 a of the receiving portion is applied to either the right or left rotation direction. The elastic force of the spring 22 acts in the axial direction (opening direction) of the closing suppression unit 8 and returns to the initial position (FIG. 7A).

また、閉止抑制部8の頭部表面には係合溝27が設けられ、この係合溝27を利用して回転させることで閉止抑制部8が浮き上がる構成となっている。この係合溝27に対してコイン等の道具を係合させてはじめて閉止抑制部8の頭部が回転するので、子供が誤使用してドラム内に入った状態で閉じ込められる危険性が低減できる。更に、この係合溝27は、(a)の初期状態において、すなわち洗濯機の使用時において、略鉛直方向になるように設定されているので、閉止抑制部8に対して正面または背面から操作しても、あるいは操作者が右または左利きであっても、操作し易い利点がある。   Further, an engagement groove 27 is provided on the head surface of the closing suppression portion 8, and the closing suppression portion 8 is lifted by rotating using the engagement groove 27. Only when a tool such as a coin is engaged with the engagement groove 27, the head of the closing suppression portion 8 rotates, so that the risk of being trapped in a state where the child misuses and enters the drum can be reduced. . Further, since the engagement groove 27 is set to be in a substantially vertical direction in the initial state of (a), that is, when the washing machine is used, the engagement groove 27 is operated from the front or the back with respect to the closing suppression portion 8. Even if the operator is right or left-handed, there is an advantage that it is easy to operate.

また、閉止抑制部8の頭部表面は、係合溝27に向かって低くなるような凹曲面を有しているため、コイン等が係合溝27に対して少しずれた位置に当接した場合でも、凹曲面に沿って係合溝27へ誘導させることができ、閉止抑制部8の操作性が向上する。   Further, since the head surface of the closing suppression portion 8 has a concave curved surface that becomes lower toward the engagement groove 27, the coin or the like abuts at a position slightly shifted from the engagement groove 27. Even in this case, it can be guided to the engaging groove 27 along the concave curved surface, and the operability of the closing suppression portion 8 is improved.

以上説明した本発明によれば、ヒンジ部のスプリング力による閉止方向へ働く力と、閉止抑制部8による閉止抑制の働きにより、簡単な構造で、蓋体7が完全に開放した状態ではなく、少し開いた状態で蓋体7を安定させることができる。ドラム式の洗濯機の場合、ヒンジ部の軸を中心として、蓋体7が略水平方向に回転するが、本発明の構成を採用すると、蓋体7が完全に開放して洗濯機周辺のスペースを制限することなく、密閉によるカビ等の発生及び子どもの閉じ込めを防止することが可能である。また、本発明では、閉止抑制部8を蓋体7側に設ける構成を採用しているので、閉止抑制部8を本体側に設ける構成と比べて、従来製品からの変更が容易であるだけでなく、メンテナンス時を含めて閉止抑制部8の取り付け・取り外し作業も簡単である。   According to the present invention described above, due to the force acting in the closing direction due to the spring force of the hinge portion and the closing suppression action by the closing suppression portion 8, the lid body 7 is not in a fully open state with a simple structure, The lid 7 can be stabilized in a slightly opened state. In the case of a drum-type washing machine, the lid 7 rotates in a substantially horizontal direction around the axis of the hinge portion. However, when the configuration of the present invention is adopted, the lid 7 is completely opened and the space around the washing machine It is possible to prevent the occurrence of mold and the like and the confinement of children without restricting. Moreover, in this invention, since the structure which provides the closure suppression part 8 in the cover body 7 side is employ | adopted, compared with the structure which provides the closure suppression part 8 in the main body side, only the change from a conventional product is easy. In addition, it is easy to attach / remove the closing suppression unit 8 including during maintenance.

更に、本発明の閉止抑制部8は、開閉調整ベース21としてラッチ部32と一体的に構成されており、必然的にラッチ部32の近傍に位置しているため、ラッチ部32から遠い場所に閉止抑制部8がある場合と比べて、閉止抑制部8が浮き上がる際のストロークを小さく(例えば8mm)しても、強い勢いで蓋体7を閉じることにより誤って閉止状態となるのを抑制できる。   Further, the closing suppression portion 8 of the present invention is integrally formed with the latch portion 32 as the opening / closing adjustment base 21 and is necessarily located in the vicinity of the latch portion 32, so that it is located far from the latch portion 32. Compared with the case where there is the closing suppression portion 8, even if the stroke when the closing suppression portion 8 is lifted is small (for example, 8 mm), it is possible to suppress the accidental closing by closing the lid 7 with a strong force. .
