Description

本発明は、ドラム式洗濯機で毛布や大容量衣類を洗濯するときに装着する、洗濯物飛び出し防止の洗濯キャップに関するものである。   The present invention relates to a laundry cap for preventing laundry from popping out when washing a blanket or large-capacity clothing with a drum-type washing machine.

従来、洗濯機において槽内部に投入した衣類が、運転中に槽の開口部から飛び出すのを防止する為に提案された構成として、二槽式洗濯機の脱水キャップの事例がある(例えば、特許文献1参照)。   Conventionally, there has been a case of a dewatering cap of a two-tank washing machine as a configuration proposed for preventing clothes thrown into a tank in a washing machine from jumping out of the opening of the tank during operation (for example, patents) Reference 1).

図5は、特許文献1に記載された、従来の衣類飛び出し防止の脱水キャップの構成を示すものである。   FIG. 5 shows a configuration of a conventional dewatering cap for preventing garment jumping described in Patent Document 1. As shown in FIG.

図5に示すように、可撓性材料で形成された略円板状の脱水キャップ21は、二槽式洗濯機22の脱水槽23内への衣類出し入れ用の開口部24より内下方に装着され、飛び出しを防止する為に開口部24の内径より外形寸法を大きく設定しているので、衣類25を入れた後、脱水キャップ21の可撓性を利用して、たわませて脱水槽23内に挿入し、開口部24を塞ぐように装着されていた。   As shown in FIG. 5, a substantially disc-shaped dewatering cap 21 formed of a flexible material is mounted inward and downward from an opening 24 for putting clothes in and out of a dewatering tank 23 of a two-tank washing machine 22. Since the outer dimension is set larger than the inner diameter of the opening 24 in order to prevent popping out, the dehydration tank 23 is bent by using the flexibility of the dehydration cap 21 after the clothing 25 is put in. It was inserted so as to close the opening 24.

上記のような二槽式洗濯機の脱水キャップを、ドラム式洗濯機に転用させた事例が、図6に示した洗濯キャップ35である。   A case where the dewatering cap of the two-tank washing machine as described above is diverted to a drum-type washing machine is a washing cap 35 shown in FIG.

図6は、ドラム式洗濯機における洗濯キャップの構成を示す断面図である。   FIG. 6 is a cross-sectional view showing the configuration of the washing cap in the drum type washing machine.

図6に示すように、ドラム式洗濯機の本体32内部に揺動自在に配した水槽36の内方に、回転自在に軸支された回転ドラム33の、開口部34を内方より覆うように可撓性材料で形成された洗濯キャップ35を配する。洗濯キャップ35は、回転ドラム33の内方に投入された毛布などの容積の大きい毛布などの衣類37などを洗う場合に、運転中に開口部34よりはみ出して、本体32の前方に配した蓋38や、水槽36と本体32との間に構成したゴム等で形成した水封用のマドパッキング39に接触して損傷を受けないように構成したものである。

(Embodiment 1)
FIG. 1 is a front view of a washing cap according to the first embodiment of the present invention, FIG. 2 is a partial cross-sectional view of a drum type washing machine showing a mounting state of the washing cap, and FIG. FIG. 4 is a partial sectional view of the washing cap, and FIG.

図1において、洗濯キャップ5は、可撓性材料で形成され所定の厚みを有す略円板状のキャップ本体6と、キャップ本体6の外周部に設けられた複数個のマグネット7とで構成される。キャップ本体6は、ドラム内に挿入する際に変形しやすくする為に、開口8を多数形成し、放射状に形成した梁部9とドーナツ状の外周部10で構成され、またマグネット7は、外周部10の周状に略均等に具備されている。   In FIG. 1, a washing cap 5 is composed of a substantially disc-shaped cap body 6 made of a flexible material and having a predetermined thickness, and a plurality of magnets 7 provided on the outer periphery of the cap body 6. Is done. The cap body 6 includes a plurality of openings 8 and a radially formed beam portion 9 and a donut-shaped outer peripheral portion 10 in order to facilitate deformation when inserted into the drum, and the magnet 7 has an outer peripheral portion. It is provided substantially evenly around the circumference of the portion 10.

図2の断面図において、ドラム式洗濯機の本体1内方には水槽3を揺動自在に配し、水槽3内部には、ステンレス鋼板等の磁性を有する材料で構成したドラム4を洗濯回転自在に軸支している。本体1の前方には、ドラム4の開口部12に対応して蓋体2を開閉自在に配し、蓋体2を閉じた状態では、水槽3の前方の開口14にゴム等の弾性体で形成したマドパッキング13にて水密的に蓋体2と水槽3とを密閉する。   In the cross-sectional view of FIG. 2, a water tub 3 is slidably disposed inside the main body 1 of the drum-type washing machine, and a drum 4 made of a magnetic material such as a stainless steel plate is washed and rotated inside the water tub 3. It is pivotally supported. In front of the main body 1, a lid body 2 is disposed so as to be openable and closable corresponding to the opening 12 of the drum 4. When the lid body 2 is closed, an elastic body such as rubber is formed in the opening 14 in front of the water tank 3. The lid 2 and the water tank 3 are hermetically sealed with the formed packing 13.

ドラム4の前方の開口部12を構成するドラム前板15のドラム4内側には、ドラム4の内部に投入された衣類11が開口部12より蓋体2側に飛び出さない様に、洗濯キャップ5を装着する。なお、この洗濯キャップ5を装着する作業は、例えば衣類11が毛布など大容量洗濯であると判断した場合に、使用者が行うものである。   A washing cap is provided on the inner side of the drum 4 of the drum front plate 15 that constitutes the opening 12 in front of the drum 4 so that the clothes 11 thrown into the drum 4 do not jump out of the opening 12 toward the lid 2. Wear 5 The operation of attaching the washing cap 5 is performed by the user when it is determined that the clothing 11 is a large-capacity laundry such as a blanket.

洗濯キャップ5は、図1においても説明したように外周部10に複数個のマグネット7を具備しているので、その磁力によりドラム前板15の内面に吸着保持する。   Since the washing cap 5 includes the plurality of magnets 7 on the outer peripheral portion 10 as described with reference to FIG. 1, the washing cap 5 is attracted and held on the inner surface of the drum front plate 15 by the magnetic force.

図3の洗濯キャップ5の部分断面図は、図1におけるA部の断面を示しており、図3において、マグネット7はコイン状の円盤に形成し、洗濯キャップ5の外周部10に設けた凹部17に挿入し、図3で右側の露出側より円形のキャップ部材16を被覆して密閉状態に保持される。   The partial cross-sectional view of the laundry cap 5 in FIG. 3 shows a cross-section of the portion A in FIG. 1. In FIG. 3, the magnet 7 is formed in a coin-shaped disk and is a recess provided in the outer peripheral portion 10 of the laundry cap 5. 17 and the circular cap member 16 is covered from the exposed side on the right side in FIG.

図4の要部分解断面図において、マグネット7の構成を説明すると、キャップ部材16は、熱可塑性材質の樹脂成形部材で構成し、外周部10の凹部17側には環状リブ18を一体形成し、凹部17の外周部に形成したリング状溝19に環状リブ18を嵌合させる。   4, the structure of the magnet 7 will be described. The cap member 16 is formed of a thermoplastic resin molded member, and an annular rib 18 is integrally formed on the concave portion 17 side of the outer peripheral portion 10. The annular rib 18 is fitted into the ring-shaped groove 19 formed in the outer peripheral portion of the recess 17.

キャップ部材16を洗濯キャップ5の外周部10に嵌合させた状態で、キャップ部材16の背面より超音波振動を加えて溶着固定する。   In a state where the cap member 16 is fitted to the outer peripheral portion 10 of the washing cap 5, ultrasonic vibration is applied from the back surface of the cap member 16 to be welded and fixed.

また、洗濯キャップ5の外周部10に設けた凹部17の底部肉厚(図4でB)は、キャップ部材16の肉厚(図4でC)と略近似するように設定している。   Further, the bottom thickness (B in FIG. 4) of the recess 17 provided on the outer peripheral portion 10 of the washing cap 5 is set to be approximately approximate to the thickness (C in FIG. 4) of the cap member 16.

なお、キャップ部材16の溶着方法は、上記例では超音波溶着としたが、接着剤よる固着であっても同様の効果は期待できる。   Although the cap member 16 is welded by ultrasonic welding in the above example, the same effect can be expected even if the cap member 16 is fixed by an adhesive.

以上のように構成された洗濯キャップについて以下その動作、作用と効果を説明する。   The operation, action, and effect of the washing cap configured as described above will be described below.

まず、洗濯キャップ5をドラム4内に挿入した場合、ドラム4内でマグネット7とドラム前板15とは磁力で吸着しようとするので、洗濯キャップ5はドラム4内部に確実に保持することができるので、ドラム内の衣類の動きや容積、大きさによって不安定にならず、ドラム駆動時の異音の発生を防止できる。   First, when the washing cap 5 is inserted into the drum 4, the magnet 7 and the drum front plate 15 are attracted by the magnetic force in the drum 4, so that the washing cap 5 can be reliably held inside the drum 4. Therefore, it does not become unstable depending on the movement, volume, and size of the clothes in the drum, and the generation of abnormal noise when the drum is driven can be prevented.

また、マグネット7は、洗濯キャップ5に形成された凹部にはめ込まれ、露出側にキャップ部材16を溶着固定し、密封構造にすることによって、洗濯キャップ5の奥行き寸法を大型化することもなく洗濯キャップ5を薄く形成することができ、ドラム4内の容積を減らさずかつ洗濯キャップ5の可撓性も損なうことがない。さらにマグネット7の取り付けは、水密的に構成されているので、洗濯水などの付着がなく鋼板等の磁性体で構成されるマグネットのさび付きを防止することができる。   In addition, the magnet 7 is fitted in a recess formed in the washing cap 5, and the cap member 16 is welded and fixed to the exposed side to form a sealed structure, so that the laundry cap 5 can be washed without increasing the depth dimension. The cap 5 can be formed thin, the volume in the drum 4 is not reduced, and the flexibility of the washing cap 5 is not impaired. Further, since the magnet 7 is attached in a watertight manner, it is possible to prevent rusting of the magnet made of a magnetic material such as a steel plate without adhesion of washing water or the like.

また、キャップ本体6のマグネット7装着部の肉厚と、キャップ部材16の肉厚とを略同一とすることにより、ドラム4への吸着力は洗濯キャップ5を表裏逆にドラム4内に挿入した場合でも同一の保持力を確保することが出来るので使い勝手が低下することは無い。   In addition, by making the thickness of the magnet 7 mounting portion of the cap body 6 substantially the same as the thickness of the cap member 16, the suction force to the drum 4 is inserted into the drum 4 with the washing cap 5 turned upside down. Even in this case, since the same holding force can be secured, the usability is not lowered.

以上のように、本発明における洗濯キャップは、衣類の傷みや破れなど不慮の事故を効果的に抑制することが可能となるので、将来高速回転での脱水機能や大容量化するドラム式洗濯機において効果が大きい。   As described above, the washing cap according to the present invention can effectively prevent unexpected accidents such as damage and tearing of clothes, so that a dewatering function at a high speed rotation in the future and a drum-type washing machine whose capacity will be increased The effect is great.
