しかしながら、前記従来の構成では、使用者が洗濯物を回転ドラム内に入れて蓋体３９を閉めた時に、誤って洗濯物の一部を内蓋５３の外周とパッキング部材４６のリップ部４６ａとの間に挟んでしまい、そのまま運転を開始したために、回転ドラムの回転により、洗濯物がパッキング部材のリップ部を巻きつけるようにして大きな力で回転ドラム内に引張り、パッキング部材が外れたり、破れたりして、水漏れが発生するという課題があった。   However, in the conventional configuration, when the user puts the laundry in the rotating drum and closes the lid 39, a part of the laundry is mistakenly placed on the outer periphery of the inner lid 53 and the lip portion 46a of the packing member 46. Since the operation was started as it was, the laundry was pulled into the rotating drum with a large force so that the lip portion of the packing member was wound by the rotation of the rotating drum, and the packing member was detached or torn. As a result, there was a problem that water leakage occurred.

図７（ａ）〜（ｃ）は、従来のドラム式洗濯機において洗濯物の一部を内蓋５３の外周とパッキング部材４６のリップ部４６ａとの間に挟んで運転を開始した場合の状態図である。   FIGS. 7A to 7C show a state in which a part of the laundry is sandwiched between the outer periphery of the inner lid 53 and the lip portion 46a of the packing member 46 in the conventional drum type washing machine and the operation is started. FIG.

洗濯物５４の一部を内蓋５３の外周とパッキング部材４６のリップ部４６ａとの間に挟んで運転を開始すると、図７（ａ）に示すように、洗濯物５４は、回転ドラム４１の回転に伴い、徐々に捩れ部分５４ａが発生してくる。さらに、運転を続けると、図７（ｂ）に示すように、リップ部４６ａが、捩れ部分５４ａに巻き込まれていく。最終的には、図７（ｃ）に示すように、洗濯物５４は、回転ドラム４１内に引き込まれていくが、その際、洗濯物５４の捩れ部分５４ａに巻き込まれたリップ部４６ａがパッキング部材４６から千切られてしまい、洗濯物５４とともに回転ドラム４１内に入り込んでしまい、パッキング部材４６からリップ部４６ａがなくなってしまうため、内蓋５３の外周とパッキング部材４６間のシールができず、水漏れが発生するというという課題があった。   When the operation is started by sandwiching a part of the laundry 54 between the outer periphery of the inner lid 53 and the lip portion 46a of the packing member 46, as shown in FIG. A torsional portion 54a is gradually generated along with the rotation. Further, when the operation is continued, as shown in FIG. 7B, the lip portion 46a is wound around the twisted portion 54a. Finally, as shown in FIG. 7C, the laundry 54 is drawn into the rotary drum 41. At this time, the lip portion 46a wound around the twisted portion 54a of the laundry 54 is packed. The member 46 is shredded and enters the rotating drum 41 together with the laundry 54, and the lip portion 46a disappears from the packing member 46, so that the outer periphery of the inner lid 53 and the packing member 46 cannot be sealed, There was a problem that water leakage occurred.

本発明は、前記従来の課題を解決するもので、洗濯物が内蓋とパッキング部材の間に挟まれたまま運転されたとしても、パッキング部材が外れたり、破れたりしないようにパッキング部材のリップ部周りを構成して、大きな水漏れの被害を起こさないドラム式洗濯機を提供することを目的とする。   The present invention solves the above-mentioned conventional problems, and even if the laundry is operated while being sandwiched between the inner lid and the packing member, the packing member lip is prevented from coming off or torn. It is an object of the present invention to provide a drum-type washing machine that is configured around the section and does not cause damage due to a large water leak.

前記課題を解決するために、本発明のドラム式洗濯機は、前面開口部を有する前面パネル部材を前面側に配設した本体と、前記本体内に揺動自在に弾性支持され前面側に水槽開口部を設けた水槽と、前記水槽に回転自在に内包され前面側にドラム開口部を設けた回転ドラムと、前記回転ドラムを回転駆動するモータと、前記前面開口部を開閉自在に覆い内方に突出する内蓋を有する蓋体と、前記前面開口部と前記水槽開口部との間に連結されゴムなどの弾性材からなるパッキング部材とを備え、前記パッキング部材は、前記前面開口部近傍から後方へ延びる略円筒部と、前記略円筒部の後端から前方かつ外方へ折り返すことにより外周側に膨出し前記水槽開口部と連結する膨出部と、前記略円筒部の前端部に設けられ前記蓋体を閉めた時に前記内蓋に当接してシールするリップ部と、前記リップ部よりも前記水槽開口部側の前記略円筒部に設けられたリブ部とを有し、前記リブ部は、前記リップ部の厚さよりも厚く、前記リップ部の高さ以上の高さに形成するとともに、前記蓋体を閉めた時に前記内蓋に接触しないように形成した構成としたものである。   In order to solve the above problems, a drum-type washing machine of the present invention includes a main body having a front panel member having a front opening disposed on the front side, and an elastically supported swingably in the main body and a water tank on the front side. A water tank provided with an opening, a rotary drum that is rotatably included in the water tank and provided with a drum opening on the front side, a motor that rotationally drives the rotary drum, and a front opening that covers the front opening freely And a packing member made of an elastic material such as rubber connected between the front opening and the water tank opening, the packing member from the vicinity of the front opening.

It is thick and formed to have a height equal to or higher than the height of the lip portion, and is formed so as not to contact the inner lid when the lid is closed.

これによって、洗濯物が誤って内蓋とパッキング部材の間に挟まれたまま運転されたとしても、洗濯物はリップ部に巻きつく前にリブ部を巻きつけて大きな力で回転ドラム内に引っ張りこもうとするが、リブ部の厚みを厚く形成しているために十分に巻きつけることができず、洗濯物がリブ部から外れてしまうことにより、パッキング部材が外れたり、破れたりして大きな水漏れが発生することを防止することができる。   As a result, even if the laundry is accidentally operated while being sandwiched between the inner lid and the packing member, the laundry is wrapped around the rib portion before being wrapped around the lip portion and pulled into the rotating drum with great force. Although it tries to stiffen, the rib part is formed thick so that it cannot be wound sufficiently, and the laundry is detached from the rib part, so that the packing member comes off or is torn. It is possible to prevent water leakage.

本発明のドラム式洗濯機は、使用者が誤って洗濯物を内蓋に挟んだまま運転したとしても、洗濯物の巻き込みによるパッキング部材の外れや破れを防ぎ、水漏れを防止することができる。   The drum type washing machine according to the present invention can prevent the packing member from coming off and tearing due to the entrainment of the laundry and preventing water leakage even if the user accidentally drives the laundry while sandwiching it in the inner lid. .

の外周面と当接してシールを行い、蓋体１６の外周からの水および蒸気の漏出を防止している。また、図３（ｂ）に示すように、リップ部１８ａは、例えば、略円筒部１８ｂの内面からの高さｃを９ｍｍ、厚さｄを３ｍｍに設定している。 3A, the packing member 18 has a substantially cylindrical portion 18b extending rearward from the front plate opening 17a of the front plate 17, and an outer circumferential side by folding back forward and outward from the rear end of the substantially cylindrical portion 18b. And a bulging portion 18c connected to the bulging water tank opening 9a. A lip portion 18a formed on the inner periphery of the front end portion of the substantially cylindrical portion 18b protrudes to the inner periphery side of the front plate opening portion 17a of the front plate 17, and when the cover body 16 is closed, Side inner lid 16a
The outer peripheral surface of the lid 16 is sealed to prevent leakage of water and steam from the outer periphery of the lid body 16. Moreover, as shown in FIG.3 (b), the lip part 18a has set height c from the inner surface of the substantially cylindrical part 18b to 9 mm, and thickness d to 3 mm, for example.

さらに、パッキング部材１８には、図３（ａ）に示すように、リップ部１８ａよりも水槽開口部９ａ側の略円筒部１８ｂにリブ部１８ｄが形成されている。リブ部１８ｄは、例えば、中心部分において、略円筒部１８ｂの内面からの高さｅを１２ｍｍ、先端部分の厚みｆを１１ｍｍ、根元部分の厚みｇを１４ｍｍに設定している。このリブ部１８ｄの高さｅの１２ｍｍは、蓋体１６を閉めた時に、内蓋１６ａに接触せず隙間を設けた高さに設定している。また、リブ部１８ｄは、リップ部１８ａから、寸法ｈ（例えば、１０ｍｍ）程度離して設けている。   Further, as shown in FIG. 3A, the packing member 18 has a rib portion 18d formed in a substantially cylindrical portion 18b closer to the water tank opening 9a than the lip portion 18a. For example, the rib portion 18d has a height e of 12 mm from the inner surface of the substantially cylindrical portion 18b, a thickness f of the tip portion of 11 mm, and a thickness g of the root portion of 14 mm at the center portion. The height e of the rib portion 18d is set to a height at which a gap is provided without contacting the inner lid 16a when the lid body 16 is closed. The rib portion 18d is provided away from the lip portion 18a by a dimension h (for example, 10 mm).

つまり、パッキング部材１８のリブ部１８ｄの厚みは、リップ部１８ａの厚みより厚く、リブ部１８ｄの高さは、リップ部１８ａの高さよりも高くなっており、また、リブ部１８ｄは蓋体１６を閉めた時に、内蓋１６ａに接触しないように形成してある。ここで、リブ部１８ｄの先端部と内蓋１６ａ間の最小隙間ｉは、本実施の形態１では、３ｍｍに設定している。これにより、リブ部１８ｄが、蓋体１６の開閉時に違和感を及ぼしたり、リップ部１８ａと内蓋１６ａ間のシール性能に影響を及ばしたりすることがないようにしている。   That is, the thickness of the rib portion 18d of the packing member 18 is thicker than the thickness of the lip portion 18a, the height of the rib portion 18d is higher than the height of the lip portion 18a, and the rib portion 18d is the lid body 16. When the is closed, it is formed so as not to contact the inner lid 16a. Here, the minimum gap i between the tip of the rib portion 18d and the inner lid 16a is set to 3 mm in the first embodiment. This prevents the rib portion 18d from feeling uncomfortable when the lid body 16 is opened and closed, or affecting the sealing performance between the lip portion 18a and the inner lid 16a.

また、リブ部１８ｄは、パッキング部材１８の略円筒部１８ｂ全周に設ける必要はなく、図４（ｂ）に示すように、蓋体１６を閉めた場合に洗濯物を挟みこんでしまう可能性がある下半円部のうち、中心線より、左右α（例えば、３５°）の範囲に設けていれば十分である。   Further, the rib portion 18d does not need to be provided on the entire circumference of the substantially cylindrical portion 18b of the packing member 18, and as shown in FIG. 4B, the laundry may be caught when the lid body 16 is closed. Of the lower semicircular part, it is sufficient if it is provided within a range of left and right α (for example, 35 °) from the center line.

また、リブ部１８ｄは、前述したとおり、中心部分において、先端部分の厚みｆを１１ｍｍとしているが、図４（ａ）に示すように、両端に行くに従い、薄くし、左右α部分の厚みｋ（例えば、６ｍｍ）としてもよい。これにより、使用者に対して、リブ部１８ｄの違和感、圧迫感等を軽減させることができる。   Further, as described above, the rib portion 18d has a thickness f of 11 mm at the tip portion at the center portion, but as shown in FIG. (For example, 6 mm) may be used. Thereby, it is possible to reduce a sense of incongruity, a feeling of pressure, and the like of the rib portion 18d for the user.

また、リブ部１８ｄの略中央部分最下部には、その前方から後方に連通する水抜き孔１８ｅが設けてあり、洗濯終了後にリップ部１８ａとリブ部１８ｄとの間に水が溜まったままになることを防止している。さらに、略円筒部１８ｂには、水抜き孔１８ｅの前後に凹状の溝１８ｆを形成している。これにより、リップ部１８ａとリブ部１８ｄとの間に溜まった水が、水抜き孔１８ｅおよび凹状の溝１８ｆを通り、スムーズに膨出部１８ｃを介して、水槽９に流れ落ちて行くようにすることができる。これによって、洗濯終了後にリップ部１８ａとリブ部１８ｄとの間に水が溜まったままになることを防止し、洗濯終了後に洗濯物を取り出す際、洗濯物に水が再付着するのを防止することができる。   Further, a drain hole 18e that communicates from the front to the rear is provided at the lowermost portion of the substantially central portion of the rib portion 18d so that water is collected between the lip portion 18a and the rib portion 18d after washing is completed. It is prevented from becoming. Further, a concave groove 18f is formed in the substantially cylindrical portion 18b before and after the drain hole 18e. Thereby, the water accumulated between the lip portion 18a and the rib portion 18d passes through the drain hole 18e and the concave groove 18f, and smoothly flows down to the water tank 9 through the bulging portion 18c. be able to. This prevents water from remaining between the lip portion 18a and the rib portion 18d after the laundry is finished, and prevents the water from reattaching to the laundry when the laundry is taken out after the laundry is finished. be able to.

なお、リップ部１８ａについては、内蓋１６ａとのシール性や蓋体１６の開閉力、あるいは耐久性の関係を検証することにより、厚み等の寸法を決定すれば良い。   For the lip portion 18a, the dimensions such as the thickness may be determined by examining the relationship between the sealing performance with the inner lid 16a, the opening / closing force of the lid body 16, or the durability.

以上のように構成したドラム式洗濯機において、以下、その動作、作用を図５（ａ）、（ｂ）を用いて説明する。   The operation and action of the drum type washing machine configured as described above will be described below with reference to FIGS. 5 (a) and 5 (b).

図５（ａ）、（ｂ）は、本発明の実施の形態１におけるドラム式洗濯機において、洗濯物の一部を内蓋の外周とパッキング部材のリップ部との間に挟んで運転を開始した場合の状態図である。   FIGS. 5 (a) and 5 (b) illustrate a drum-type washing machine according to Embodiment 1 of the present invention, in which a part of the laundry is sandwiched between the outer periphery of the inner lid and the lip portion of the packing member, and operation is started. FIG.

洗濯行程の始めに、洗濯物１９を回転ドラム１０内に投入して洗濯を開始しようとして
、誤って洗濯物を蓋体１６の内蓋１６ａとパッキング部材１８の間に挟んだ状態で運転した場合、洗濯物１９が内蓋１６ａとパッキング部材１８の間に挟まれたまま、回転ドラム１０内に設けたバッフル１１の回転に伴って洗濯物も回転しようとする。 At the beginning of the washing process, when the laundry 19 is put into the rotary drum 10 to start washing, the laundry is accidentally operated with the laundry sandwiched between the inner lid 16a of the lid 16 and the packing member 18 While the laundry 19 is sandwiched between the inner lid 16a and the packing member 18, the laundry also tries to rotate as the baffle 11 provided in the rotary drum 10 rotates.

図５（ａ）に示すように、洗濯物１９は、回転ドラム１０の回転に伴って、徐々に捩れ部分１９ａが発生してくる。このとき、ねじれ部分１９ａは、リップ部１８ａよりも洗濯物１９に近く高さが高いリブ部１８ｄの内側で発生し、リブ部１８ｄを巻きつけようとする。しかし、図５（ｂ）に示すように、リブ部１８ｄは厚みが厚いために、ねじれによる剪断力が作用せず、ねじれ部分１９ａは、徐々に大きくなるとともに、洗濯物１９自体が、回転ドラム１０内に引き込まれて行き、内蓋１６ａとパッキング部材１８の間から外れてしまい、洗濯物１９は回転ドラム１０内で正常に攪拌されることになる。   As shown in FIG. 5A, the laundry 19 gradually has a twisted portion 19 a as the rotary drum 10 rotates. At this time, the twisted portion 19a is generated inside the rib portion 18d that is closer to the laundry 19 and higher in height than the lip portion 18a, and tries to wind the rib portion 18d. However, as shown in FIG. 5B, since the rib portion 18d is thick, shearing force due to twisting does not act, the twisted portion 19a gradually increases, and the laundry 19 itself becomes a rotating drum. 10 is pulled into the interior 10 and detached from between the inner lid 16 a and the packing member 18, and the laundry 19 is normally stirred in the rotary drum 10.

なお、本実施の形態１においては、リブ部１８ｄの略円筒部１８ｂの内面からの高さｅ（１２ｍｍ）を、リップ部１８ａの略円筒部１８ｂの内面からの高さｃ（９ｍｍ）より高く設定したが、両者の高さが同等であっても、内蓋１６ａの形状（中心方向への傾斜具合）次第で、上記と同等の作用効果を得ることができる。   In the first embodiment, the height e (12 mm) of the rib portion 18d from the inner surface of the substantially cylindrical portion 18b is higher than the height c (9 mm) of the lip portion 18a from the inner surface of the substantially cylindrical portion 18b. Although set, the same effects as described above can be obtained depending on the shape of the inner lid 16a (inclination in the center direction) even if the heights of both are equal.

そして、リブ部１８ｄの略円筒部１８ｂの内面からの高さｅを、５ｍｍ≦ｅ＜１５ｍｍに設定することで、リブ部１８ｄの先端部と内蓋１６ａ間の最小隙間ｉを、０ｍｍ＜ｉ≦１０ｍｍに設定したであれば、ねじれ部分１９ａが、リブ部１８ｄの先端部を越えて、リップ部１８ａに至る確率を減少させることができる。   Then, by setting the height e of the rib portion 18d from the inner surface of the substantially cylindrical portion 18b to 5 mm ≦ e <15 mm, the minimum gap i between the tip portion of the rib portion 18d and the inner lid 16a is set to 0 mm <i. If it is set to ≦ 10 mm, the probability that the twisted portion 19a reaches the lip portion 18a beyond the tip end portion of the rib portion 18d can be reduced.

ただ、リブ部１８ｄの先端部と内蓋１６ａ間の最小隙間ｉを、５ｍｍ＜ｉ≦１０ｍｍに設定した場合、略円筒部１８ｂの内面からの高さｅを５ｍｍ≦ｅ＜１０ｍｍにすることができ、リブ部１８ｄを目立たなくすることができる反面、ねじれ部分１９ａが、リブ部１８ｄの先端部を乗り越えて、洗濯物１９のねじれ部分１９ａがリップ部１８ａに巻きついてしまう可能性が２回にほぼ１回の確率で発生してしまう。   However, when the minimum gap i between the tip of the rib portion 18d and the inner lid 16a is set to 5 mm <i ≦ 10 mm, the height e from the inner surface of the substantially cylindrical portion 18b may be 5 mm ≦ e <10 mm. Although the rib portion 18d can be made inconspicuous, there is a possibility that the twisted portion 19a gets over the tip of the rib portion 18d and the twisted portion 19a of the laundry 19 is wrapped around the lip portion 18a twice. It occurs almost once.

そこで、リブ部１８ｄの先端部と内蓋１６ａ間の最小隙間ｉを、０ｍｍ＜ｉ≦５ｍｍに設定することで、ねじれ部分１９ａが、リブ部１８ｄの先端部と内蓋１６ａ間で挟み込まれるため、ねじれ部分１９ａが、確実にリップ部１８ａに至るのを防止することができ、洗濯物１９がリップ部１８ａに巻きつくのを防ぐことができ、パッキング部材１８の外れ、破れを防止でき、大きな水漏れが発生することを防止することができる。   Therefore, the torsional portion 19a is sandwiched between the tip end of the rib portion 18d and the inner lid 16a by setting the minimum gap i between the tip end of the rib portion 18d and the inner lid 16a to 0 mm <i ≦ 5 mm. The twisted portion 19a can be surely prevented from reaching the lip portion 18a, the laundry 19 can be prevented from being wrapped around the lip portion 18a, and the packing member 18 can be prevented from coming off and torn. It is possible to prevent water leakage.

以上のように、本実施の形態１においては、パッキング部材１８は、前方開口部１５ａ近傍から後方へ延びる略円筒部１８ｂと、略円筒部１８ｂの後端から前方かつ外方へ折り返すことにより外周側に膨出し水槽開口部９ａと連結する膨出部１８ｃと、略円筒部１８ｂの前端部に設けられ蓋体１６を閉めた時に内蓋１６ａに当接してシールするリップ部１８ａと、リップ部１８ａよりも水槽開口部９ａ側の略円筒部１８ｂに設けられたリブ部１８ｄとを有し、リブ部１８ｄは、リップ部１８ａの厚さよりも厚く、リップ部１８ａの高さ以上の高さに形成するとともに、蓋体１６を閉めた時に内蓋１６ａに接触しないように形成した構成とすることにより、洗濯物１９が誤って内蓋１６ａとパッキング部材１８の間に挟まれたまま運転された場合には、洗濯物１９はリップ部１８ａよりも近い位置にあるリブ部１８ｄを巻きつけて大きな力で回転ドラム１０内に引っ張りこもうとするが、リブ部１８ｄの厚みを厚く形成しているために十分に巻きつけることができず、洗濯物がリップ部１８ａおよびリブ部１８ｄから外れてしまうことにより、パッキング部材１８が外れたり、破れたりすることを防いで、大きな水漏れが発生することを防止することができる。   As described above, in the first embodiment, the packing member 18 has an outer periphery formed by folding back substantially forward from the rear end of the substantially cylindrical portion 18b and the substantially cylindrical portion 18b extending rearward from the vicinity of the front opening 15a. A bulging portion 18c that is connected to the bulging water tank opening 9a, a lip portion 18a that is provided at the front end of the substantially cylindrical portion 18b and seals against the inner lid 16a when the lid body 16 is closed; Rib portion 18d provided in substantially cylindrical portion 18b on the water tank opening 9a side than 18a, and rib portion 18d is thicker than the thickness of lip portion 18a and is higher than the height of lip portion 18a. In addition, the laundry 19 is operated while being accidentally sandwiched between the inner lid 16a and the packing member 18 by being configured not to contact the inner lid 16a when the lid 16 is closed. Place The laundry 19 tries to pull the rib portion 18d closer to the lip portion 18a and pull it into the rotary drum 10 with a large force, but the rib portion 18d is formed thick. It is not possible to sufficiently wind the laundry, and the laundry is detached from the lip portion 18a and the rib portion 18d, so that the packing member 18 is prevented from being detached or torn, and a large water leak occurs. Can be prevented.

以上のように、本発明にかかるドラム式洗濯機は、使用者が誤って洗濯物を蓋体に挟んだまま運転したとしても、洗濯物の巻き込みによるパッキング部材の外れや破損を防止して、水漏れを防止できるので、蓋体と回転機能を有する他の洗濯機の用途に適用できる。   As described above, the drum type washing machine according to the present invention prevents the packing member from being detached or damaged due to the entrainment of the laundry, even if the user accidentally operates the laundry with the lid sandwiched between the lids. Since water leakage can be prevented, the present invention can be applied to other washing machines having a lid and a rotating function.
