Description

本発明は、ドラム式洗濯機の外箱側面の構成に関するものである。   The present invention relates to a configuration of a side surface of an outer box of a drum type washing machine.

従来、この種のドラム式洗濯機の外箱側面構成においては、脱水時等の振動を低減する為に、プレス加工等による薄板鋼板に水平方向に凹状絞り部を複数条形成することが提案されてきた（例えば、特許文献１参照）。   Conventionally, in this type of drum-type washing machine outer case side surface configuration, in order to reduce vibration during dehydration, etc., it has been proposed to form a plurality of concave constricted portions in a horizontal direction on a thin steel plate by pressing or the like. (For example, see Patent Document 1).

図４は、特許文献１に記載された従来のドラム式洗濯機の外観斜視図を示すものである。図４に示すように、縦長略直方体の外箱４１構成は、上面に上面化粧カバー３０、前面上方に表示等も備えた操作パネル３１、前面中央に開閉自在にドア３２を配した前面化粧カバー３３、前面下方に前面下部カバー３４、下方には脚部３９を取り付けた脚台３５を構成する。   FIG. 4 shows an external perspective view of a conventional drum type washing machine described in Patent Document 1. As shown in FIG. As shown in FIG. 4, the configuration of the outer box 41 of a substantially vertically long rectangular parallelepiped is composed of an upper face decorative cover 30 on the upper surface, an operation panel 31 having a display and the like on the upper front, and a front decorative cover having a door 32 that can be opened and closed at the front center. 33, a front lower cover 34 is formed below the front surface, and a leg base 35 with a leg portion 39 attached below is formed.

外箱４１の側面には、薄板鋼板で形成した縦長略矩形の左右両面の側面板３６で外箱全体構成の重量を脚台３５と共に支えるものである。   On the side surface of the outer box 41, the weight of the entire outer box structure is supported together with the leg stand 35 by side plates 36 on the left and right sides of a vertically long and substantially rectangular shape formed of a thin steel plate.

上記側面板３６には、製品持ち運び用の把手部３８や、注意シール等貼りつけ凹部４０を形成しているので、その部分は除いて、側面全面に水平方向に長手方向を有する凹状絞り部３７を複数条形成する。前記凹状絞り部３７は、その凹状絞り部の面積、即ち塑性変形をしている面積を、凹状絞り部３７を加工していない部分の面積より広くすることにより、側面板３６全体の面剛性を高め、側面板３６の持つ共振周波数を大きくし、脱水時の振動周波数から遠ざけることで外箱４１の振動を低減する面剛性を高めるものであった。   Since the side plate 36 is formed with a handle portion 38 for carrying the product and a concave portion 40 for attaching a caution seal or the like, the concave diaphragm portion 37 having a longitudinal direction in the horizontal direction on the entire side surface except for the portion. Form multiple lines. The concave diaphragm portion 37 has a surface rigidity of the entire side plate 36 by making the area of the concave diaphragm portion, that is, the area where plastic deformation is performed, larger than the area of the portion where the concave diaphragm portion 37 is not processed. The surface rigidity of the outer casing 41 is reduced by increasing the resonance frequency of the side plate 36 and increasing the resonance frequency away from the vibration frequency during dehydration.

そして、凹状絞り部３７を側面板全面に水平方向に設定しているが、これは側面板３６が縦方向に縦長略矩形をしているので、凹状絞り部３７の上下幅として設定した寸法Ｐが一定ならば、凹状絞り部３７の数を多数構成できるからで、凹状絞り部３７を多数構成して面剛性を高める構成であった。   The concave diaphragm portion 37 is set in the horizontal direction on the entire side plate. This is because the side plate 36 has a substantially rectangular shape in the vertical direction, and the dimension P set as the vertical width of the concave diaphragm portion 37. Is constant, it is possible to configure a large number of concave diaphragm portions 37, so that a large number of concave diaphragm portions 37 are configured to increase the surface rigidity.

特開２０１０−６３８９３号公報JP 2010-63893 A

しかしながら、前記従来の構成では、側面板が縦方向に縦長略矩形している場合には凹状絞り部の数を多数構成でき、特に縦方向の面剛性を高めることができるが、側面板の形状が略４角形に近い形状の場合には、例えば上下一方向の剛性は高めることができても、側面板に加わる振動は、水平方向あるいは上下のいずれの方向からでも伝達してくるので、剛性は必ずしも十分とはいえないものであった。   However, in the conventional configuration, when the side plate is substantially rectangular in the vertical direction, a large number of concave diaphragm portions can be configured, and in particular, the surface rigidity in the vertical direction can be increased. In the case of a shape close to a square, for example, even if the vertical rigidity can be increased, the vibration applied to the side plate is transmitted from either the horizontal direction or the vertical direction. Was not necessarily sufficient.

従って、脱水運転時に側面板の振動が増大し異音の発生や、前面中央のドアの操作で特に閉じる際に強い力で操作した際に、側面板の振動にて反響し異音が発生するという課題があった。   Therefore, the vibration of the side plate increases during dehydration operation, and abnormal noise is generated, and when operating with a strong force especially when closing the front center door, the side plate vibrates and generates abnormal noise. There was a problem.

本発明は、上記従来の課題を解決するもので、側面板に加わる振動が、水平方向あるいは上下のいずれの方向から伝達されても、側面板の面剛性を高め、振動や異音の発生を低減することを目的としている。   The present invention solves the above-mentioned conventional problems, and even if vibration applied to the side plate is transmitted from either the horizontal direction or the upper and lower directions, the surface rigidity of the side plate is increased and vibration and abnormal noise are generated. The purpose is to reduce.

前記従来の課題を解決する為に、本発明のドラム式洗濯機は、外箱の側面部を構成し鋼板で形成した左右の側面板と、前記外箱の前面部を構成し前面略中央に開閉自在にドアを配した前面カバーと、前記外箱の上面を構成する上面カバーと、前記外箱内方に回転ドラムを回転自在に軸支持した水槽と、前記水槽を揺動自在に垂下防振支持するサスペンションと、外箱底板から前記水槽の振動を減衰する減衰ダンパーと、前記水槽の前記ドア側にて前記前面カバーと水密的に固定したドアパッキンとを備え、前記左右の側面板は凹状絞り部を複数条形成し、前記凹状絞り部は、前記ドア側である前面に近いほど大きい曲率の円弧形状とし、後方に向かうにつれて曲率が小さくなる円弧形状としたものである。   In order to solve the above-mentioned conventional problems, the drum type washing machine of the present invention comprises left and right side plates formed of steel plates that constitute the side portion of the outer box, and the front portion of the outer box at the substantially front center. A front cover provided with doors that can be opened and closed, an upper surface cover that constitutes the upper surface of the outer box, a water tank that rotatably supports a rotating drum inside the outer box, and a drooping prevention mechanism that allows the water tank to swing freely The suspension includes a suspension for vibration support, a damping damper that attenuates vibration of the water tank from an outer box bottom plate, and a door packing that is watertightly fixed to the front cover on the door side of the water tank. A plurality of concave diaphragm portions are formed, and the concave diaphragm portions have an arc shape with a larger curvature as it approaches the front surface on the door side, and an arc shape with a curvature that decreases toward the rear.

これにより、脱水運転時の水槽あらゆる方向の挙動に対応した側面板の面剛性を確保でき、低振動・低騒音が達成される。   Thereby, the surface rigidity of the side plate corresponding to the behavior of the water tank in all directions during the dehydration operation can be secured, and low vibration and noise can be achieved.

本発明のドラム式洗濯機は、いかなる形状の側面板にも対応して面剛性を高め得るので、高速脱水時の外箱の振動を低減することで、低振動・低騒音を達成することができる。   Since the drum type washing machine of the present invention can increase the surface rigidity corresponding to any shape of the side plate, low vibration and low noise can be achieved by reducing the vibration of the outer box during high-speed dewatering. it can.

第１の発明は、外箱の側面部を構成し鋼板で形成した左右の側面板と、前記外箱の前面部を構成し前面略中央に開閉自在にドアを配した前面カバーと、前記外箱の上面を構成する上面カバーと、前記外箱内方に回転ドラムを回転自在に軸支持した水槽と、前記水槽を揺動自在に垂下防振支持するサスペンションと、外箱底板から前記水槽の振動を減衰する減衰ダンパーと、前記水槽の前記ドア側にて前記前面カバーと水密的に固定したドアパッキンとを備え、前記左右の側面板は凹状絞り部を複数条形成し、前記凹状絞り部は、前記ドア側である前面に近いほど大きい曲率の円弧形状とし、後方に向かうにつれて曲率が小さくなる円弧形状としたことにより、脱水運転時の水槽あらゆる方向の挙動に対応した側面板の面剛性を確保でき、低振動・低騒音が達成される。   The first invention comprises left and right side plates that are formed of a steel plate that constitutes a side portion of the outer box, a front cover that constitutes the front portion of the outer box and that is provided with a door that can be opened and closed substantially at the center of the front surface, A top cover that constitutes the top surface of the box, a water tank that rotatably supports a rotating drum inside the outer box, a suspension that supports the water tank in a swingable manner, and a suspension plate that supports the water tank in a swingable manner. A damping damper that damps vibration; and a door packing that is watertightly fixed to the front cover on the door side of the water tank, and the left and right side plates form a plurality of concave throttle portions, and the concave throttle portions The surface rigidity of the side plate that corresponds to the behavior of the water tank in all directions during dehydration operation by adopting an arc shape with a larger curvature closer to the front side that is the door side and a curvature that decreases toward the rear Can ensure low vibration And low noise is achieved.

第２の発明は、ドア側である前面に最も近い位置の凹状絞り部は略半円形状としたことにより、脱水運転時、ドア近傍のドアパッキンを介して側面板から振動が伝達されてくる振動に対し、扇形凹状絞り部により強い面剛性が得られるので、側面板全体への振動伝達が低減され、製品全体の振動の抑制を行うことができる。また、ドアを解放状態から、強い力で閉じる操作をした際には、ドアパッキンおよび前面カバーを介して左右の側面板に衝撃が伝わる際にも、脱水運転時と同様、扇形凹状絞り部の強い面剛性により、側面板全体の反響音が低減される。   In the second invention, the concave diaphragm portion closest to the front surface on the door side has a substantially semicircular shape, so that vibration is transmitted from the side plate via the door packing in the vicinity of the door during the dehydration operation. Since strong surface rigidity is obtained by the fan-shaped concave diaphragm portion against vibration, vibration transmission to the entire side plate is reduced, and vibration of the entire product can be suppressed. In addition, when the door is closed with a strong force from the open state, when the impact is transmitted to the left and right side plates via the door packing and front cover, Due to the strong surface rigidity, the echo sound of the entire side plate is reduced.

以下、本発明の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 of the present invention will be described with reference to the drawings. Further, the present invention is not limited by this embodiment.

（実施の形態１）
図１は、本発明の第１の実施の形態におけるドラム式洗濯機の外観斜視図を示すものであり、図２は、同ドラム式洗濯機の側面方向から見た縦断面図を、図３は、同ドラム式洗濯機の側面版の正面図を示すものである。 (Embodiment 1)
FIG. 1 is an external perspective view of the drum type washing machine according to the first embodiment of the present invention. FIG. 2 is a longitudinal sectional view of the drum type washing machine as viewed from the side. These show the front view of the side version of the drum type washing machine.

図１において、略立方体の外箱１構成は、上面に上面化粧カバー（上面カバー）２、前面上方に表示等も備えた操作パネル３、前面中央に開閉自在にドア４を配した前面化粧カバー（前面カバー）５、前面下方に前面下部カバー６、下方には脚部７を構成する。   In FIG. 1, the structure of the substantially cubic outer box 1 consists of a top decorative cover (top cover) 2 on the upper surface, an operation panel 3 with a display on the upper front, a front decorative cover having a door 4 that can be opened and closed at the front center. (Front cover) 5, a front lower cover 6 is formed below the front surface, and a leg portion 7 is formed below.

外箱１の側面には、薄板鋼板で形成した略正方形または矩形の側面板８（図１は、右側面板を図示しており左右対称に反対側には左側面板が存在する）で外箱全体構成の重量を脚部７と共に支える。   On the side surface of the outer box 1 is a substantially square or rectangular side plate 8 formed of a thin steel plate (FIG. 1 shows the right side plate, and the left side plate exists on the opposite side in a symmetrical manner). Supports the weight of the construction together with the legs 7.

上記側面板８には、前記ドア４側である前面側から、後方に行くに従って、平面形状が曲率の異なる凹状絞り部９を複数条形成している。この側面板に形成した凹状絞り部９により薄板鋼板の側面板８の面剛性を高め、製品の脱水運転時の側面板８の振動や異音の低減と、強い操作力でドア４を閉じた際の側面板８の反響音等を削減するものである。   The side plate 8 is formed with a plurality of concave diaphragm portions 9 having different curvatures in the planar shape from the front side which is the door 4 side toward the rear. The concave diaphragm portion 9 formed on the side plate increases the surface rigidity of the side plate 8 of the thin steel plate, and the door 4 is closed with a strong operation force and the vibration and noise of the side plate 8 during the dehydration operation of the product. This reduces the reverberation sound of the side plate 8 at the time.

図２の縦断面図により、側面板に作用する振動を説明する。   The vibration acting on the side plate will be described with reference to the longitudinal sectional view of FIG.

外箱１の内方には、モータ１０にて回転駆動される回転ドラム１１が、水槽１２内に回転自在に軸支持される。前記水槽１２は、上部を上面化粧カバー２よりサスペンション１３にて揺動自在に垂下防振支持されると共に、下部では外箱底板１５から減衰ダンパー１４にて振動振幅低下させるように減衰支持される。   A rotating drum 11 that is rotationally driven by a motor 10 is rotatably supported in the water tank 12 inside the outer box 1. The upper part of the water tank 12 is supported by the suspension 13 so that the upper part of the water tank 12 can swing freely. The lower part of the water tank 12 is damped and supported by the damping damper 14 so as to reduce the vibration amplitude. .

さらに、水槽１２の前方のドア４側には、ドア４を閉じた時にドア内ガラス１６と水密的に接するゴム等可撓性材質のドアパッキン１７で前面化粧カバー５に水密的に固定されている。   Further, the front door 4 side of the water tank 12 is watertightly fixed to the front decorative cover 5 with a door packing 17 made of a flexible material such as rubber that comes in watertight contact with the inner glass 16 when the door 4 is closed. Yes.

水槽１２の、特に脱水運転時の高速回転では、回転ドラム１１内部に洗濯物衣類１８は多種多様な分布をするので水槽１２の挙動は上下、左右、前後と複雑な動きを生じる。   When the aquarium 12 is rotated at a high speed particularly during a dehydrating operation, the laundry garment 18 has a wide variety of distributions inside the rotating drum 11, so that the behavior of the aquarium 12 causes complicated movements such as up and down, left and right, and front and rear.

従って、サスペンション１３や、減衰ダンパー１４より上面化粧カバー２や底板１５を介して側面板８（図２では図示せず）に伝達される振動は、上下方向の波動が主体となる一方、水槽１２が前後方向の挙動の場合にはドアパッキン１７より、前面化粧カバー５を介して側面板８（図２では図示せず）に伝達される。   Therefore, the vibration transmitted from the suspension 13 and the damping damper 14 to the side plate 8 (not shown in FIG. 2) via the top decorative cover 2 and the bottom plate 15 is mainly composed of vertical waves, while the water tank 12. Is transmitted from the door packing 17 to the side plate 8 (not shown in FIG. 2) via the front decorative cover 5.

従って、側面板８の剛性は、サスペンション１３や、減衰ダンパー１４より上面化粧カバー２や底板１５を介して側面板８に伝達される主として上下方向の振動と、ドアパッキン１７部より、前面化粧カバー５を介してドア４側の前方から側面板８に伝達される水平方向の振動、及びドア開閉時の水平方向の衝撃、に対応する面剛性が必要となる。   Therefore, the rigidity of the side plate 8 is mainly the vertical vibration transmitted from the suspension 13 and the damping damper 14 to the side plate 8 via the top decorative cover 2 and the bottom plate 15, and the front packing 17 from the door packing 17 part. Therefore, it is necessary to have surface rigidity corresponding to the horizontal vibration transmitted from the front side of the door 4 to the side plate 8 via 5 and the horizontal impact when the door is opened and closed.

特に、側面板形状が、前後より上下方向寸法が大きく勝る縦長略矩形でなく、前後と上下方向寸法が近似した矩形や正方形状に近い形状の場合には、側面板剛性は上下と前後方向に同様の面剛性が特に求められる。   In particular, when the shape of the side plate is not a vertically long and roughly rectangular shape whose vertical dimension is significantly greater than that of the front and rear, but a shape close to a rectangle or square whose front and rear and vertical dimensions are approximated, the rigidity of the side plate is determined in the vertical and longitudinal directions. Similar surface rigidity is particularly required.

図３の側面板の正面図において、側面板８の凹状絞り部９は、ドア４の最前側にある略半円（略半楕円）凹状絞り部９ａ、ドア４の前側から略円弧形状の曲率の大きい凹状絞り部９ｂから、順次後方に行くに従って９ｃ、９ｄ、９ｅ、と曲率を小さく変化させた形状に形成している。なお、凹状絞り部９の「凹」は外箱１の外方から外箱１の内方に向けて「凹」状となっている。   In the front view of the side plate in FIG. 3, the concave diaphragm portion 9 of the side plate 8 has a substantially semicircular (substantially semi-elliptical) concave diaphragm portion 9 a on the foremost side of the door 4, and a substantially arc-shaped curvature from the front side of the door 4. 9c, 9d, and 9e are formed in a shape in which the curvature is gradually changed from the concave diaphragm portion 9b having a large diameter toward the rear. In addition, the “concave” of the concave diaphragm portion 9 has a “concave” shape from the outside of the outer box 1 toward the inside of the outer box 1.

曲率の設定は、懸垂曲線（カテナリー）で設定し、図３で、ドア４側に最も近接した位置に略半円凹状絞り部９ａを構成し、とくに側面板のドア側中央部近傍の面剛性を高めている。   The curvature is set by a catenary curve, and in FIG. 3, a substantially semicircular concave throttle portion 9a is formed at a position closest to the door 4 side. Is increasing.

一方、ドア４側から最も離れた図３で右端の凹状絞り部９ｅの平面形状は略垂直に近似する曲率の小さい円弧状のカテナリー曲線に構成し、上下の端部Ａが側面板の上下角隅部１９に近接するように形成し、凹状絞り部の面積をできるだけ広くしている。   On the other hand, the planar shape of the concave diaphragm 9e at the right end in FIG. 3 farthest from the door 4 side is configured as an arc-shaped catenary curve having a small curvature approximating a substantially vertical shape, and the upper and lower ends A are the upper and lower angles of the side plate. It is formed so as to be close to the corner portion 19, and the area of the concave diaphragm portion is made as wide as possible.

なお、鋼板材質の側面板８の板厚を０．６ｍｍとした場合、前記凹状絞り部９は、プレス加工等により２．０〜４．０ｍｍの深さに絞り加工を施すことで塑性変形させ、側面板の面剛性を高めている。   When the thickness of the side plate 8 made of a steel plate is 0.6 mm, the concave drawn portion 9 is plastically deformed by drawing to a depth of 2.0 to 4.0 mm by pressing or the like. The surface rigidity of the side plate is increased.

また、凹状絞り部９ｂ、９ｃ、９ｄ、９ｅの上下方向の中心は、ドア４の中心ならびに回転ドラム１１の回転軸上にあるほうが好適である。   In addition, it is preferable that the vertical centers of the concave diaphragm portions 9 b, 9 c, 9 d, and 9 e lie on the center of the door 4 and the rotation axis of the rotary drum 11.

以上のように構成した洗濯機について、その動作、作用を説明する。   About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated.

近年、ドラム式洗濯機は節水効果が大きいとして、その需要が増加すると共に、洗える衣類容量の増大化の製品開発が進んできた。その対応として、図２で示した回転ドラム１１の回転軸方向さ長さ（奥行き）を増やすことで対応が進んでいる。従って、容量増大に伴い製品自体の奥行きが大きくなり、側面板８も、従来は上下に縦長形状の矩形が多かったが、近年は前後と上下方向寸法が近似した矩形や、正方形状に近い形状が増えている。   In recent years, the drum type washing machine has a great water-saving effect, so that the demand for the drum-type washing machine has been increased and the development of products for increasing the washable clothes capacity has been advanced. As the countermeasure, the countermeasure is advanced by increasing the length (depth) of the rotating drum 11 in the rotation axis direction shown in FIG. Therefore, as the capacity increases, the depth of the product itself increases, and the side plate 8 has conventionally had a vertically long rectangular shape, but in recent years, a rectangular shape that approximates the front and rear and vertical dimensions, or a shape that is close to a square shape. Is increasing.

そのような状況で、本願の側面板は、サスペンション１３や、減衰ダンパー１４より上面化粧カバー２や底板１５を介して側面板８に伝達される主として上下方向の振動と、ドアパッキン１７より、前面化粧カバー５を介してドア４側の前方から側面板８に伝達される水平方向の振動の２方向に対応するように、画一的な縦方向凹状絞り部や、水平方向のみの凹状絞り部で面剛性を確保するのでなく、複雑な複数条の円弧凹状絞り部を構成したもので、各円弧により、縦方向、水平方向の面剛性を高めている。   Under such circumstances, the side plate of the present application is mainly driven by the vertical vibration transmitted from the suspension 13 and the damping damper 14 to the side plate 8 via the top decorative cover 2 and the bottom plate 15, and from the door packing 17. A uniform vertical squeezing part or a squeezing squeezing part only in the horizontal direction so as to correspond to two directions of horizontal vibration transmitted from the front side of the door 4 to the side plate 8 via the decorative cover 5 In addition to ensuring the surface rigidity, a complicated plurality of circular arc concave diaphragm portions are configured, and the surface rigidity in the vertical and horizontal directions is enhanced by each arc.

特に、脱水運転時、ドア４近傍のドアパッキン１７を介して側面板８にＢ方向（図３）から振動が伝達されてくる振動に対し、略半円凹状絞り部９ａにより強い面剛性が得られるので、側面板８全体への振動伝達が低減され、製品全体の振動の抑制を行うことができる。   In particular, during the dehydrating operation, strong surface rigidity is obtained by the substantially semicircular concave throttle portion 9a against vibration transmitted from the B direction (FIG. 3) to the side plate 8 via the door packing 17 near the door 4. Therefore, vibration transmission to the entire side plate 8 is reduced, and vibration of the entire product can be suppressed.

また、ドア４を解放状態から、強い力で閉じる操作をした際には、ドアパッキン１７および前面化粧カバー５を介して左右の側面板に衝撃が伝わる際にも、脱水運転時と同様、略半円凹状絞り部９ａの強い面剛性により、側面板８全体の反響音が低減される。   Further, when the door 4 is closed with a strong force from the released state, the impact is transmitted to the left and right side plates via the door packing 17 and the front decorative cover 5 as in the dehydration operation. Due to the strong surface rigidity of the semicircular concave diaphragm 9a, the reverberant sound of the entire side plate 8 is reduced.

以上のように、本発明にかかるドラム式洗濯機は、側面板の面剛性、とくに前面ドア近傍を高めることにより脱水時の外箱振動や、ドア開閉時の異音を低減させることができるので、振動を伴い、かつ開閉ドアを有する他の製品、たとえば脱水機等の用途にも適用できる。   As described above, the drum type washing machine according to the present invention can reduce the vibration of the outer box during dehydration and the abnormal noise when opening and closing the door by increasing the surface rigidity of the side plate, particularly the vicinity of the front door. It can also be applied to other products with vibration and having an open / close door, such as a dehydrator.
