It can be suppressed from being damaged.
- the protrusion shape of the contact portion 8 may be one for each of the two cushioning members 7, but in the present embodiment, as shown in FIGS. 5 and 6, a plurality of protrusions are not one. It is formed in the shape of individual protrusions. Specifically, the contact portion 8 is formed in a protrusion shape corresponding to the shape of the contact surface 7a of the cushioning member 7, that is, the circular shape of the contact surface 7a of the cushioning member 7. More specifically, the contact portion 8 has a plurality of protrusion shapes including one protrusion shape and six protrusion shapes arranged on the circumference of a circle centered on the center of the one protrusion shape. Is formed in. This shape is a geometric arrangement of circles of the same diameter, and can be incorporated as a design in a well-balanced manner without any discomfort.
- the tip of the protrusion of the contact portion 8 is too thin, the shock absorbing performance is deteriorated and the deformation of the contact surface 7a of the cushioning member 7 is large. Further, in some cases, it is presumed that the user may be injured by touching it, so it is preferable to form it so as to have an appropriate roundness such as a hemisphere.
- the washing operation of the washing machine 10 is no different from that of a general washing machine. That is, the user opens the lid 5, puts the laundry into the washing tub 3 through the opening 2a, puts the detergent into the detergent case (not shown), and closes the lid 5. Then, the user turns on the power, sets the washing course by the operation display unit 4, and starts the operation. In the washing course, the washing step, the rinsing step and the dehydration step are basically performed in order.

Deformation can be suppressed.
- the washing machine 10 includes an upper frame body 2 of the main body 1 having an opening 2a into which laundry is taken in and out, and a lid 5 for opening and closing the opening 2a.
- the lid 5 is pivotally supported by the upper frame 2 and has a buffer member 7 that cushions an impact that abuts on the upper frame 2 when closed.
- the contact area of the contact portion 8 of the upper frame body 2 with which the cushioning member 7 abuts is larger than the contact area when the cushioning member 7 contacts the flat surface 2b of the upper frame body 2. Is also formed into a small protrusion shape.
- the washing machine 10 can make the contact area between the cushioning member 7 of the lid 5 and the contact portion 8 of the upper frame 2 smaller. Therefore, in the washing machine 10, even if the cushioning member 7 adheres to the contact portion 8 of the upper frame body 2 due to the relatively long contact between the cushioning member 7 and the upper frame body 2, the cushioning member 7 The area to which is attached can be reduced. Therefore, the washing machine 10 can prevent the appearance quality from being impaired by making the color transfer to the upper frame body 2 inconspicuous.
- the contact portion 8 is formed in a hemispherical protrusion shape. As a result, the contact surface 7a of the cushioning member 7 is not deformed so much that the shock absorbing performance is deteriorated, and the user does not get injured by touching it.
- the contact portion 8 is formed in a plurality of protrusions. As a result, color transfer is visually reduced due to the shadow generated by the plurality of protrusion shapes. Further, since the contact portion 8 supports the cushioning member 7 at a plurality of points, the washing machine 10 can suppress deformation due to concentration of the load on one point of the contact surface 7a of the cushioning member 7. Further, in the washing machine 10, even if a slight positional deviation occurs when the lid 5 is closed, any one of the plurality of protrusion shapes can abut and support the cushioning member 7.

Abstract
Description
発明者らが本開示に想到するに至った当時、蓋体に備え付けられた弾性体の緩衝部材と上部枠体との比較的長時間の接触に伴い、緩衝部材が熱などにより溶け出したり、擦れ合ったりして、緩衝部材が上部枠体の接触部に付着する状態が発生していた。また、特に、上部枠体と緩衝部材の色が異なる場合、その色移りが目立ち、外観品位が損なわれてしまっていた。そこで、これらを同系色で構成する方法も考えられるが、緩衝部材はゴム材料で、上部枠体は樹脂材料で形成され、材質が異なるため、光の反射具合の違いなどにより、使用者には異物が付着したように見え、外観品位が損なわれることには違いはなかった。また、これらの材料を、より摩擦に強い材料または劣化が小さい材料とすることも考えられるが、いずれも相応のコストアップとなる。このため、緩衝部材が上部枠体に付着してしまったとしても、上部枠体の接触部における外観品位が損なわれることを抑制すると言う課題を発明者らは発見し、その課題を解決するために、本開示の主題を構成するに至った。
以下、図1~図6を用いて、実施の形態1を説明する。
[1-1-1.洗濯機の構成]
まず、実施の形態1における洗濯機10の構成を、図1および図2を用いて説明する。図1は、洗濯機10の蓋体5が閉じた状態の外観斜視図であり、図2は、洗濯機10の蓋体5が開いた状態の外観斜視図である。
次に、緩衝部材7および突起形状に形成される接触部8の構成を、図3~図6を用いて説明する。図3は、洗濯機10の蓋体5が有する緩衝部材7の斜視図である。図4Aは、接触部8の第1の例の縦断面図であり、図4Bは、接触部8の第2の例の縦断面図である。図5は、接触部8の斜視図である。また、図6は、洗濯機10の蓋体5が閉められた状態の要部側断面図である。なお、図4Aおよび図4Bは、図5に示す接触部8を形成する複数個の突起形状のうちの1個の突起形状の例を示している。
[1-2-1.洗濯機の動作]
以上のように構成された洗濯機10について、以下その動作、作用を説明する。
洗濯機10が使用される中で、使用者が洗濯物を洗濯槽3に投入して洗濯運転を行うとき、あるいは、使用者が洗濯機10を使用し終わったとき、図1に示すように、蓋体5は閉じられる。このとき、蓋体5の裏に設けられる緩衝部材7は、開口部2aの前方の上部枠体2に設けられる接触部8に衝突して、蓋体5が閉じられる衝撃を緩和する。そして、図6に示すように、洗濯機10が運転されている間、あるいは、使用者が次に洗濯機10を使用するまで、蓋体5は閉じられた状態で、蓋体5の重量の多くが緩衝部材7にかかった状態が継続される。
以上のように、本実施の形態において、洗濯機10は、洗濯物が出し入れされる開口部2aを有する本体1の上部枠体2と、開口部2aを開閉する蓋体5とを備える。蓋体5は、上部枠体2に軸支され、閉じられるときに上部枠体2に当接する衝撃を緩衝する緩衝部材7を有する。そして、緩衝部材7が当接する上部枠体2の接触部8は、接触部8と緩衝部材7との接触面積が、緩衝部材7が上部枠体2の平面2bに接触した場合における接触面積よりも小さい突起形状に形成される。
以上のように、本出願において開示する技術の例示として、実施の形態1を説明した。しかしながら、本開示における技術は、これに限定されず、変更、置き換え、付加、省略などを行った実施の形態にも適用できる。また、上記実施の形態1で説明した各構成要素を組み合わせて、新たな実施の形態とすることも可能である。
