Description

【発明の詳細な説明】 ムの役目をなすベースの改良に関するものである。[Detailed description of the invention] This is related to the improvement of the base that plays the role of the system.

二槽式洗たく機のベース部の構成は第１図に示すように
なっている。The structure of the base of the two-tub washing machine is shown in FIG.

即ち，パルセータプーリ−１をベルト２を介して駆動す
る洗たくモータ３を防振ゴム４を介してベース５上に防
振支持する。That is, a washing motor 3 that drives a pulsator pulley 1 via a belt 2 is supported on a base 5 via a vibration isolating rubber 4 in a vibration-proof manner.

一方，脱水槽６を直結駆動する脱水モータ７を防振バネ
８を介してベース５上に防振支持する。On the other hand, a dehydration motor 7 that directly drives the dehydration tank 6 is vibration-proofly supported on the base 5 via a vibration-proof spring 8.

洗たく槽９，脱水槽６の水受け１０の排水は、バルブ１
１にて開閉制御され外部排水ボース１２により機外へ放
水される。Drainage from the water receptacle 10 of the washing tank 9 and dehydration tank 6 is done through valve 1.
1, the opening and closing are controlled and water is discharged to the outside of the machine through an external drainage bowl 12.

１３は外枠を示す。13 indicates an outer frame.

このような構成のベース部において，ベース５は従来板
厚０．７〜１．０ｍｍの鋼板のプレス作業により製作さ
れてきたが、多くの行程を要し生産性がわるく、かつ防
錆力に問題があり、近時プラスチックスの射出成形品が
採用されるようになってきた。In the base part with such a structure, the base 5 has conventionally been manufactured by pressing a steel plate with a thickness of 0.7 to 1.0 mm, but this requires many steps, reduces productivity, and has poor rust prevention properties. Due to this problem, plastic injection molded products have recently been adopted.

ところが、このプラスチックスでは鋼板に比べ著しく強
度が低いため成形品の肉厚を太きくせねばならず、この
ため逆に材料コストがかかつて採算に合わない欠点を有
する。However, since the strength of this plastic is significantly lower than that of steel plate, the wall thickness of the molded product must be made thicker, which has the disadvantage that the material cost increases and is often unprofitable.

また、材料も最も安価なポリプロピレン樹脂が用いられ
るが、これは、衝撃強度が低い欠点があり、輸送時にモ
ータにかかる衝撃力で割れる問題がある。In addition, polypropylene resin, which is the cheapest material, is used, but this has the disadvantage of low impact strength, and there is a problem that it will break due to the impact force applied to the motor during transportation.

この出来るだけ薄い肉厚で、つまり最少の材料費でいか
に強度を出すかが、ベースの合成樹脂化設計の最大の難
問であった。The biggest challenge in designing the synthetic resin base was how to achieve strength with the thinnest possible wall thickness, or in other words, the lowest material cost.

本発明はこの雅量に徘戦したもので、平均肉厚２〜２．
５ｍｍという薄肉で輸送衝撃に充分耐える合成樹脂のベ
ースを供給することができるようにした点に関するもの
である。しかも、合成樹脂の特性である、被雑な形状が
自由に出せることを利用して、最大限に多機能化するこ
とによってこれまでの鋼板ベースにない数々の効果を生
むようにしたものである。The present invention addresses this problem, and has an average wall thickness of 2 to 2.
This invention relates to the provision of a synthetic resin base that is as thin as 5 mm and sufficiently resistant to transportation impact. Furthermore, by taking advantage of the ability of synthetic resin to freely create complex shapes, it is made to be as multifunctional as possible, producing a number of effects not available with conventional steel plate bases.

即ち、洗たくモータ３に３本のアームを形成し。That is, three arms are formed in the washing motor 3.

この各アームをそれぞれ防振ゴム４を介して防振支持す
る３個の支持台２ｏをタワー状に形成し、各支持台２０
間及び外周フランジ部を口又は几状のビーム２１にて結
合する形をとっている。Three support stands 2o are formed in a tower shape to provide vibration-proof support for each of the arms via anti-vibration rubber 4, and each support stand 20
The gap and outer flange portion are connected by a mouth or a box-shaped beam 21.

この状態は、第３図及び第４図に示す通りである。This state is as shown in FIGS. 3 and 4.

このようにすることにより、まずモータの支持台２０が
、第１面に示す従来例のような平面部になっていず、高
さＨが高い円筒状のフランジ２３に支えられた極めて平
面部の小さい面で受けられるので、衝撃力を受けてもこ
の支持台２ｏ自体が破壊されることは絶無である。By doing this, first, the motor support stand 20 is not a flat part like the conventional example shown on the first surface, but is an extremely flat part supported by a cylindrical flange 23 with a high height H. Since the impact force is received by a small surface, there is no possibility that the support stand 2o itself will be destroyed even if it receives an impact force.

次にこの支持台２０を強い外周フランジ２２と几状のビ
ームで結んでいる。Next, this support stand 20 is connected to a strong outer circumferential flange 22 by a box-shaped beam.

このビームは第５図に示すように衝撃荷重Ｗが働いたと

ることができる。When this beam is subjected to an impact load W as shown in Fig. 5, the neutral axis o-o' of its cross section is
A compressive force σC acts on the upper side, and a tensile force σt acts on the lower side.The parts of the beam 24 that receive the maximum compressive stress σC are given to both side beams 25 and 26, and are able to maintain sufficient strength. can. Next, the beams on both sides 25.26
Since the lower side is only subjected to the tensile stress σt, sufficient strength can be maintained without deforming in the direction of the dotted line in FIG.

７図の点線のように変形してしまい充分な強度を保つこ

形時の型離れがよく成形性もよい利点を有する。On the other hand, with the conventional square-shaped ribs shown in Figure 1, compressive stress is applied to the ribs on both upward facing sides, which easily deforms as shown by the dotted lines in Figure 7, making it impossible to maintain sufficient strength. . Moreover, all of these reinforcing structures have the advantage of being easy to release from the mold during molding and having good moldability.

この成形時の型離れのよさは、第７図に示す断面かられ
かるように、これらのビームが全て上下の型の合わせに
よってつくられており、均一な肉厚を保持してしかも型
離れ時に、多少点線のようにひらけることに起因しも）
る。The ease of release from the mold during molding is due to the fact that all of these beams are made by fitting the upper and lower molds together, as can be seen from the cross section shown in Figure 7. (This may be due to the fact that it opens out somewhat like a dotted line)
Ru.

この型離れがよいことは、無理にぬくことによって生ず

アップにいっそう寄与する。This good release from the mold means that there will be no minute cracks in some corners that would be caused by forceful removal, which further contributes to increased strength.

o is formed in the shape of a truncated cone with a bottom, and the space between the support bases 30 and the support base 30 and the outer peripheral flange 22 is formed into a shape of a beam 3.
It is tied at 1.

その補強効果は前記洗たくモータ３の支持構成に説明し
た通りである。The reinforcing effect is as explained in the support structure of the washing motor 3 above.

以上により、均一な平均２〜２　、５　ｍ／ｍの肉厚で
充分なる強度を有するベースを得ることができ、材料を
軽減させることができる。As described above, it is possible to obtain a base having sufficient strength with a uniform thickness of 2 to 2.5 m/m on average, and to reduce the amount of material required.

本発明によれば、以上に示すように生産性がよく、強度
も充分な洗たく機用ベースを提供しうるものである。According to the present invention, as described above, it is possible to provide a washing machine base with good productivity and sufficient strength.
