以下、実施の形態について、図面を参照しながら説明する。また、この実施の形態によって本発明が限定されるものではない。
Hereinafter, embodiments will be described with reference to the drawings. Further, the present invention is not limited to this embodiment.
（実施の形態１）

FIG. 1 is an external perspective view of the washing machine according to the first embodiment in a closed state. FIG. 2 is an external perspective view of the washing machine with the lid open.
図１は、実施の形態１における洗濯機の蓋体が閉じた状態の外観斜視図である。図２は、同洗濯機の蓋体が開いた状態の外観斜視図である。 (Embodiment 1)
FIG. 1 is an external perspective view of the washing machine according to the first embodiment in a closed state. FIG. 2 is an external perspective view of the washing machine with the lid open.
図１及び図２に示すように、洗濯機本体１の上部にはトップカバー２が配設されている。トップカバー２の上面には衣類投入口５が形成されている。衣類投入口５から投入された衣類は、洗濯機本体１の内部に配設された洗濯槽６に収容される。蓋体３は、衣類投入口５の上方を覆うように開閉自在に設けられている。蓋体３周りの詳細構造は、後述する。
As shown in FIGS. 1 and 2, a top cover 2 is arranged on the upper part of the washing machine main body 1. A clothing inlet 5 is formed on the upper surface of the top cover 2. The clothes thrown in from the clothes throwing port 5 are housed in the washing tub 6 arranged inside the washing machine main body 1. The lid 3 is provided so as to be openable and closable so as to cover the upper part of the clothing inlet 5. The detailed structure around the lid 3 will be described later.
蓋体３の後方には、各種の入力設定を行ない、設定内容を表示する操作表示部４が配設されている。操作表示部４の下方には、洗濯機の運転制御を行う制御装置（図示せず）が配設されている。
Behind the lid 3, an operation display unit 4 for performing various input settings and displaying the setting contents is arranged. A control device (not shown) that controls the operation of the washing machine is arranged below the operation display unit 4.
続いて、蓋体３周りの詳細構造を説明する。図３は、実施の形態１における洗濯機の蓋体の開閉状態を示す側面図である。
Next, the detailed structure around the lid 3 will be described. FIG. 3 is a side view showing an open / closed state of the lid of the washing machine according to the first embodiment.
図３に示すように、蓋体３は、洗濯機の後方左右端部で軸支されている。蓋体３は、蓋ヒンジ軸を回動中心として、閉塞状態ＬＯの位置から垂直に開いた位置である開放状態ＬＨの位置まで、回動可能に構成されている。蓋体３が開放状態ＬＨから閉じられる時には、Ｌ１の位置を過ぎてから、後述するダンパー構造により回転動作が緩和される。これにより、急激な衝撃を蓋体３に与えないで、蓋体３はＬＯ位置で閉じる。
As shown in FIG. 3, the lid 3 is pivotally supported at the rear left and right ends of the washing machine. The lid body 3 is configured to be rotatable around the lid hinge axis from the position of the closed state LO to the position of the open state LH which is a vertically open position. When the lid 3 is closed from the open state LH, the rotation operation is relaxed by the damper structure described later after passing the position of L1. As a result, the lid 3 is closed at the LO position without giving a sudden impact to the lid 3.
図４は、実施の形態１における洗濯機の蓋体周りの構造を示す分解斜視図である。
FIG. 4 is an exploded perspective view showing the structure around the lid of the washing machine according to the first embodiment.
図４に示すように、蓋体３の後方右部には、右方向に延伸するように形成された回動軸２１が配設されている。また、蓋体３の後方左部にはダンパー構造が配設されている。なお、洗濯機を前方から見た洗濯機の右側を右側と定義し、洗濯機を前方から見た洗濯機の左側を左側と定義する。ダンパー構造は、蓋体３に形成された蓋体空間１３と、蓋体空間１３に収容されるダンパー保持体１０と、ダンパー保持体１０により保持されるダンパー９により構成されている。ダンパー９は、左方向に延伸するように形成された四角柱形状のダンパー軸９ａと、回転動作を緩和させる内部構造を備えている。また、ダンパー構造の前面はカバー体１１により覆われており、外部から蓋体空間１３の内部構造が見えないようになっている。
As shown in FIG. 4, a rotating shaft 21 formed so as to extend to the right is arranged on the rear right portion of the lid 3. Further, a damper structure is arranged on the rear left portion of the lid body 3. The right side of the washing machine when viewed from the front is defined as the right side, and the left side of the washing machine when viewed from the front is defined as the left side. The damper structure is composed of a lid space 13 formed in the lid 3, a damper holding body 10 housed in the lid space 13, and a damper 9 held by the damper holding body 10. The damper 9 includes a quadrangular prism-shaped damper shaft 9a formed so as to extend to the left, and an internal structure for relaxing the rotational movement. Further, the front surface of the damper structure is covered with the cover body 11, so that the internal structure of the lid body space 13 cannot be seen from the outside.
また、トップカバー空間１４ａ及びトップカバー空間１４ｂは、トップカバー２の後方上面の左右に窪みとして形成されている。トップカバー空間１４ａはトップカバー２の後方左部に、トップカバー空間１４ｂはトップカバー２の後方右部にそれぞれ配置されており、それぞれ対応する軸受体８ａ及び軸受体８ｂが挿入される。軸受体８ａはダンパー９と係合し、軸受体８ｂは回動軸２１と遊嵌することで、蓋体３を回動自在に支持する。
Further, the top cover space 14a and the top cover space 14b are formed as recesses on the left and right of the rear upper surface of the top cover 2. The top cover space 14a is arranged at the rear left portion of the top cover 2, and the top cover space 14b is arranged at the rear right portion of the top cover 2, and the corresponding bearing bodies 8a and bearing bodies 8b are inserted, respectively. The bearing body 8a engages with the damper 9, and the bearing body 8b is loosely fitted with the rotating shaft 21 to rotatably support the lid body 3.
図５は、実施の形態１における洗濯機の蓋体の軸受体周囲の構造を示す縦断面図である。
FIG. 5 is a vertical cross-sectional view showing the structure around the bearing body of the lid of the washing machine according to the first embodiment.
図５に示すように、軸受体８の下部はトップカバー空間１４と緩く嵌合するように形成されている。ここでは、ダンパー構造側に配置される軸受体８ａについて説明する。軸受体８ａの上部には四角形状の軸受穴２０ａが形成されている。軸受穴２０ａにはダンパー軸９ａが挿入されている。なお、回動軸２１側に配置される軸受体８ｂには、軸受穴２０ａの代わりに円形の貫通孔である軸受孔２０ｂ（図４参照）が形成されている。軸受孔２０ｂには回動軸２１（図４参照）が遊嵌している。
As shown in FIG. 5, the lower portion of the bearing body 8 is formed so as to loosely fit with the top cover space 14. Here, the bearing body 8a arranged on the damper structure side will be described. A square bearing hole 20a is formed in the upper part of the bearing body 8a. A damper shaft 9a is inserted into the bearing hole 20a. The bearing body 8b arranged on the rotation shaft 21 side is formed with a bearing hole 20b (see FIG. 4) which is a circular through hole instead of the bearing hole 20a. A rotating shaft 21 (see FIG. 4) is loosely fitted in the bearing hole 20b.
軸受体８ａの下部は、後方の面である第一の面２２が、前方の面である第二の面２３よりも低くなるように段差状に形成されている。第一の面２２と第二の面２３の段差である第三の面２４は、第一の面２２及び第二の面２３に対して垂直に形成されている。なお、軸受体８ｂの下部も、軸受体８ａと同様に段差状に形成される。換言すると、軸受体８の下部は、第二の面２３と、第二の面２３よりさらに下方に突出してトップカバー空間１４の内部に配置される第一の面２２とに区分されている。そして、第一の面２２および第二の面２３は、トップカバー２にネジ１２でネジ止めされている。
The lower portion of the bearing body 8a is formed in a stepped shape so that the first surface 22 which is the rear surface is lower than the second surface 23 which is the front surface. The third surface 24, which is a step between the first surface 22 and the second surface 23, is formed perpendicular to the first surface 22 and the second surface 23. The lower portion of the bearing body 8b is also formed in a stepped shape like the bearing body 8a. In other words, the lower portion of the bearing body 8 is divided into a second surface 23 and a first surface 22 that protrudes further downward from the second surface 23 and is arranged inside the top cover space 14. The first surface 22 and the second surface 23 are screwed to the top cover 2 with screws 12.
第一の面２２の側面下部には係合凹部１７が形成されている。トップカバー空間１４ａにおいて係合凹部１７と嵌合する位置には、係合爪１５が形成されている。係合爪１５は、軸受体８ａがトップカバー空間１４に挿入される際に係合凹部１７と係合する。これにより、軸受体８ａはトップカバー空間１４ａに対して仮固定される。また、第二の面２３及び第一の面２２にはネジ穴１９がそれぞれ形成されており、軸受体８ａはネジ穴１９においてネジ１２により下方からネジ止めされている。なお、軸受体８ｂの下部も、軸受体８ａと同様に係合爪１５により仮止めされ、第二の面２３及び第一の面２２において下方よりネジ止めされている。
An engaging recess 17 is formed in the lower part of the side surface of the first surface 22. An engaging claw 15 is formed at a position in the top cover space 14a where the engaging recess 17 is fitted. The engaging claw 15 engages with the engaging recess 17 when the bearing body 8a is inserted into the top cover space 14. As a result, the bearing body 8a is temporarily fixed to the top cover space 14a. Further, screw holes 19 are formed on the second surface 23 and the first surface 22, respectively, and the bearing body 8a is screwed from below by the screws 12 in the screw holes 19. The lower part of the bearing body 8b is also temporarily fixed by the engaging claws 15 like the bearing body 8a, and is screwed from below on the second surface 23 and the first surface 22.
図６は、実施の形態１における洗濯機の蓋体の軸受体周囲の構造を下から見た横断面図である。
FIG. 6 is a cross-sectional view of the structure around the bearing body of the lid of the washing machine according to the first embodiment as viewed from below.
図６に示すように、トップカバー空間１４ａ及びトップカバー空間１４ｂの側面には、上下方向に伸びるリブ１６が設けられている。軸受体８ａ及び軸受体８ｂには、リブ１６が挿入されるように形成された溝１８が設けられている。トップカバー２の後方左部に形成されたトップカバー空間１４ａには、右側側面にリブ１６が形成されている一方、トップカバー２の後方右部に形成されたトップカバー空間１４ｂは、左側側面にリブ１６が形成されている。従って、回動軸２１側に配置される軸受体８ｂをダンパー構造側のトップカバー空間１４ａに挿入しようとしても嵌合しない。これにより、軸受体８をトップカバー空間１４に取り付ける際に、ダンパー構造側の軸受体８ａと回動軸２１側の軸受体８ｂを取り違えることを抑止できる。このため、取り付け工程における作業性を向上できる。
As shown in FIG. 6, ribs 16 extending in the vertical direction are provided on the side surfaces of the top cover space 14a and the top cover space 14b. The bearing body 8a and the bearing body 8b are provided with a groove 18 formed so that the rib 16 is inserted. The top cover space 14a formed in the rear left portion of the top cover 2 has ribs 16 formed on the right side surface, while the top cover space 14b formed in the rear right portion of the top cover 2 is formed on the left side surface. The rib 16 is formed. Therefore, even if the bearing body 8b arranged on the rotating shaft 21 side is inserted into the top cover space 14a on the damper structure side, it does not fit. As a result, when the bearing body 8 is attached to the top cover space 14, it is possible to prevent the bearing body 8a on the damper structure side and the bearing body 8b on the rotating shaft 21 side from being mistaken for each other. Therefore, workability in the mounting process can be improved.
また、本実施の形態のように、軸受体８ｂの右側側面に第２の溝２５を設けてもよい。これにより、ダンパー構造を設けない機種を製造する際に、軸受体８ａの代わりに軸受体８ｂをトップカバー空間１４ａに挿入することが可能となるため、部品の共通化を実現することができる。ただし、第２の溝２５を設けない方が、ダンパー構造側の軸受体８ａと回動軸２１側の軸受体８ｂを取り違えることをより抑止できる。
Further, as in the present embodiment, the second groove 25 may be provided on the right side surface of the bearing body 8b. As a result, when manufacturing a model without a damper structure, the bearing body 8b can be inserted into the top cover space 14a instead of the bearing body 8a, so that parts can be standardized. However, if the second groove 25 is not provided, it is possible to prevent the bearing body 8a on the damper structure side and the bearing body 8b on the rotating shaft 21 side from being mistaken for each other.
以上の構成について、以下、動作を説明する。
The operation of the above configuration will be described below.
図７は、実施の形態１における洗濯機の蓋体の軸受体周囲で発生する応力を示す模式図である。
FIG. 7 is a schematic view showing the stress generated around the bearing body of the lid body of the washing machine according to the first embodiment.
図７に示すように、蓋体３が重力により閉じる向きに動く際、矢印Ａ向きの回転モーメントが生じる。この時、ダンパー軸９ａが非円形形状であるため、軸受体８ａに対して固定点であるネジ１２の締結部を中心に大きな応力が発生する。
As shown in FIG. 7, when the lid 3 moves in the closing direction due to gravity, a rotational moment in the direction of arrow A is generated. At this time, since the damper shaft 9a has a non-circular shape, a large stress is generated around the fastening portion of the screw 12 which is a fixing point with respect to the bearing body 8a.
しかしながら、本実施の形態における軸受体８ａは、高さの異なる第一の面２２及び第二の面２３にネジ１２による締結部を設けているため、応力が蓋体落下荷重の作用面２６（破線で示す）の全体に分散する。
However, in the bearing body 8a of the present embodiment, since the first surface 22 and the second surface 23 having different heights are provided with the fastening portions by the screws 12, the stress is applied to the lid body drop load acting surface 26 ( Disperse throughout (indicated by the broken line).
また、本実施の形態における軸受体８ａは、トップカバー２と別部品で構成されているため、材料を自由に選定することができる。従って、蓋体の自然落下による回転モーメントが大きい時は剛性の高い材料を選定したり、円柱状の回転軸を有する時は剛性の低い材料を選定したりできる。
Further, since the bearing body 8a in the present embodiment is composed of a separate part from the top cover 2, the material can be freely selected. Therefore, when the rotational moment due to the free fall of the lid is large, a material with high rigidity can be selected, and when the lid has a columnar rotating shaft, a material with low rigidity can be selected.
以上のように、実施の形態１における洗濯機は、洗濯機本体１と、洗濯機本体１の上部に配設されたトップカバー２と、トップカバー２に形成された衣類投入口５と、衣類投入口５の上部を開閉自在に覆うように配設された蓋体３と、蓋体３を回動自在に支持する軸受体８と、を備える。トップカバー２の上面には、軸受体８が挿入されるトップカバー空間１４が形成されており、軸受体８の下部は、トップカバー空間１４に挿入される側の第一の面２２と、空間に挿入される側の面よりも高い位置に形成された第二の面２３とを有している。第一の面２２および第二の面２３は、トップカバー２とネジ止めされる。
As described above, the washing machine according to the first embodiment includes the washing machine main body 1, the top cover 2 arranged on the upper part of the washing machine main body 1, the clothes inlet 5 formed on the top cover 2, and the clothes. It includes a lid 3 arranged so as to cover the upper portion of the insertion port 5 so as to be openable and closable, and a bearing body 8 that rotatably supports the lid 3. A top cover space 14 into which the bearing body 8 is inserted is formed on the upper surface of the top cover 2, and the lower portion of the bearing body 8 is a space with the first surface 22 on the side to be inserted into the top cover space 14. It has a second surface 23 formed at a position higher than the surface on the side to be inserted into the. The first surface 22 and the second surface 23 are screwed to the top cover 2.
これにより、軸受体８の剛性が向上し、かつトップカバー空間１４と軸受体８の接触する表面積が増加し、蓋体３の回転時に発生する応力を分散させることができる。そのため応力集中によるトップカバー２及び軸受体８の破損を防ぐことができる。
As a result, the rigidity of the bearing body 8 is improved, the surface area in contact between the top cover space 14 and the bearing body 8 is increased, and the stress generated when the lid body 3 is rotated can be dispersed. Therefore, damage to the top cover 2 and the bearing body 8 due to stress concentration can be prevented.
本実施の形態のように、蓋体３は、蓋体３の回動運動を減衰させるダンパー９を備え、ダンパー９に設けられたダンパー軸９ａは、軸受体８ａに形成された非円形状の軸受穴２０ａに嵌合されているようにしてもよい。
As in the present embodiment, the lid 3 includes a damper 9 that attenuates the rotational movement of the lid 3, and the damper shaft 9a provided on the damper 9 has a non-circular shape formed on the bearing body 8a. It may be fitted in the bearing hole 20a.
