Description
本発明は、前面に開閉自在に扉体を配したドラム式洗濯機に関するものである。 The present invention relates to a drum-type washing machine having a door body that is openable and closable on the front surface.
従来、この種のドラム式洗濯機は、洗濯兼脱水槽を水平配置し回転駆動し、洗濯物を出し入れする開口部が洗濯機筐体の正面側に形成され、扉体によって開閉自在に閉じられる。 Conventionally, in this type of drum type washing machine, a washing and dewatering tub is horizontally arranged and rotationally driven, and an opening through which laundry is taken in and out is formed on the front side of the washing machine casing, and can be opened and closed by a door body. .
扉体は押ボタンの操作によって開かれ、運転中には開かないようにロックされ、回転駆動される洗濯兼脱水槽に手が差し込まれる危険性や洗濯水や洗濯物が外部に飛散する状態を回避できるように構成されている（例えば、特許文献１参照）。 The door body is opened by operating the push button, locked so that it does not open during operation, and there is a risk that hands will be inserted into the washing and dewatering tub that is driven to rotate, and washing water and laundry will splash outside. It is comprised so that it can avoid (for example, refer 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図を示すもので、洗濯機筐体２の正面側上部には上向きの傾斜面２ａが形成され、この傾斜面２ａに開閉自在に円形の扉体８が設けられ、前記扉体８は、傾斜面２ａに配設された扉開ボタン５６を押圧することによって開くことができる。 FIG. 4 shows an external view of a conventional drum-type washing machine described in Patent Document 1, and an upward inclined surface 2a is formed on the upper front side of the washing machine casing 2, and the inclined surface 2a A circular door body 8 is provided that can be freely opened and closed, and the door body 8 can be opened by pressing a door opening button 56 disposed on the inclined surface 2a.
図５は、扉開ボタン５６を押圧して前記扉体８を開いた状態を示し、この開いた状態で衣類を内部の洗濯兼脱水槽５内に洗濯物を投入し、扉体８を閉じて運転開始させると、扉体８は、扉体８の内側に突設されたラッチ９０が扉体８を閉じたときに嵌り込むラッチ受９１に嵌り込み、洗濯機筐体２の傾斜面２ａ内部の構成した開閉ロック部５９により扉閉状態にロックされる。 FIG. 5 shows a state in which the door opening button 56 is pressed and the door body 8 is opened. In this opened state, clothes are put into the washing / dehydrating tub 5 inside the door body 8 and the door body 8 is closed. When the operation is started, the door body 8 is fitted into the latch receiver 91 which is fitted when the latch 90 protruding from the inside of the door body 8 is closed, and the inclined surface 2a of the washing machine casing 2 is fitted. The door is locked in a closed state by an open / close lock portion 59 configured inside.
図６は、傾斜面２ａの外装材を取り外した状態で、扉体開閉操作の構成を示す平面図で、図７は、図６のＡ−Ｂ線の垂直断面を示し、図８は、図６のＣ−Ｄ線の水平断面を示す。 FIG. 6 is a plan view showing the configuration of the door body opening / closing operation with the exterior material of the inclined surface 2a removed, FIG. 7 shows a vertical section taken along the line AB of FIG. 6, and FIG. 6 shows a horizontal section taken along line CD.
図６に示すように、扉開ボタン５６と開閉ロック部５９とが引張りバネとして形成された係合スプリング（第２付勢手段）６９で係合した状態に配設されている。前記開閉ロック部５９には、扉体８の内側に突設されたラッチ９０が扉体８を閉じたときに嵌り込むラッチ受９１が形成されており、このラッチ受９１と扉開ボタン５６とは傾斜面２ａ上に外部露出する。 As shown in FIG. 6, the door opening button 56 and the opening / closing lock portion 59 are disposed in an engaged state by an engagement spring (second urging means) 69 formed as a tension spring. The opening / closing lock portion 59 is formed with a latch receiver 91 that is fitted when a latch 90 protruding from the inside of the door body 8 closes the door body 8. Is exposed to the outside on the inclined surface 2a.
以下、扉体８が閉じられた状態から、扉開ボタン５６を押圧することにより、扉体８を開放状態にする過程を説明する。 Hereinafter, a process of opening the door body 8 by pressing the door opening button 56 from the closed state of the door body 8 will be described.
図６および図８に示すように、扉開ボタン５６は回動軸５６ａにより規制範囲内で回動できるように保持されており、常時は内部に取り付けられた押上バネ（第３付勢手段）９２は前記係合スプリング６９が連結された開閉操作部材９３に当接してバネ付勢により上限位置まで押上げられた状態にある。 As shown in FIGS. 6 and 8, the door opening button 56 is held by a rotation shaft 56a so as to be able to rotate within a restricted range, and is normally a push-up spring (third biasing means) attached inside. A state 92 is in contact with the opening / closing operation member 93 to which the engagement spring 69 is connected and is pushed up to the upper limit position by the spring bias.
ここで、扉開ボタン５６を図７または図８で示した矢印の方向からＰの加重で押圧すると、押上バネ９２が圧縮され、押上バネ９２に併設された押圧突起９４が前記開閉操作部材９３に当接して開閉操作部材９３をその回動軸９３ａを回動支点として回動させるので、開閉操作部材９３に一端が係合する係合スプリング６９に引っ張り力を及ぼす。 Here, when the door open button 56 is pressed with a weight of P from the direction of the arrow shown in FIG. 7 or FIG. 8, the push-up spring 92 is compressed, and the push protrusion 94 provided along with the push-up spring 92 is moved to the opening / closing operation member 93. Since the opening / closing operation member 93 is rotated about the rotation shaft 93a as a rotation fulcrum, a pulling force is applied to the engagement spring 69 whose one end is engaged with the opening / closing operation member 93.
上記係合スプリング６９は、一定の張力を有するように開閉操作部材９３と、開閉ロック部５９間に組み立てられている。 The engagement spring 69 is assembled between the opening / closing operation member 93 and the opening / closing lock portion 59 so as to have a constant tension.
係合スプリング６９に引っ張り力を生じると、開閉ロック部５９内部の係合スプリング６９の他端が係合する引張りピン１１１を操作して、引張りピン１１１に連動した係止板（係止部材）１１３を支軸１１４を回動させて、ラッチ受９１に嵌り込んでいた図５で示した扉体８のラッチ９０を開放する。 When a pulling force is generated in the engaging spring 69, the pulling pin 111 engaged with the other end of the engaging spring 69 in the opening / closing lock part 59 is operated, and a locking plate (locking member) interlocked with the pulling pin 111 is operated. 113, the support shaft 114 is rotated, and the latch 90 of the door body 8 shown in FIG.
上記係止板（係止部材）１１３は、開閉ロック部５９内部の係止バネ１１２により、常時ラッチ受９１にて扉体８のラッチ９０を係着するように付勢されている。 The locking plate (locking member) 113 is urged so that the latch 90 of the door body 8 is always engaged by the latch receiver 91 by the locking spring 112 inside the opening / closing lock part 59.
以上のように、扉開ボタン５６を押圧する力は、押上バネ９２の反力に抗して開閉操作部材９３を回動させ、更に係合スプリング６９の張力を介して係止バネ１１２にて付勢された係止板（係止部材）１１３を回動させねばならない。 As described above, the force for pressing the door opening button 56 rotates the opening / closing operation member 93 against the reaction force of the push-up spring 92, and further, the locking spring 112 via the tension of the engagement spring 69. The biased locking plate (locking member) 113 must be rotated.
また、扉開ボタン５６の回動方向は、図６の水平なＣ−Ｄ線に沿って動作し、一方、開
閉操作部材９３の回動方向は図７のＡ−Ｂ線の垂直線に沿って動作する。
Further, the rotation direction of the door opening button 56 operates along the horizontal CD line in FIG. 6, while the rotation direction of the opening / closing operation member 93 is along the vertical line AB in FIG. Works.
扉開ボタン５６の押圧を解除すると、係止板１１３は係止バネ１１２の付勢により回動して、その突起部１１３ａをラッチ受９１内に進出させた位置に戻り、引張りピン１１１は後退移動するので、係合スプリング６９に引かれる開閉操作部材９３は回動し、押上バネ９２の付勢が働いて扉開ボタン５６は元の位置に復帰する。 When the pressing of the door opening button 56 is released, the locking plate 113 is rotated by the urging force of the locking spring 112 to return to the position where the projection 113a is advanced into the latch receiver 91, and the pulling pin 111 moves backward. Since it moves, the opening / closing operation member 93 pulled by the engagement spring 69 rotates, and the urging force of the push-up spring 92 works to return the door opening button 56 to its original position.
扉体８を開放状態から閉じの状態にするには、使用者が扉体８を押圧し、扉体８のラッチ９０が、係止板１１３を押圧し、係止バネ１１２の付勢力に抗して係止板１１３を回動させ係着させることにより再び扉ロック状態になる。
近年、この種の洗濯機の操作性を高める要求が高まっており、特に扉体８の開閉操作は、洗濯機使用時には、必ず操作を必要とする作業であり、扉開ボタン５６の形状を大きくして操作しやすくする、また、押圧力を小さくして操作性を高めることが求められる。 In recent years, there has been an increasing demand for improving the operability of this type of washing machine. In particular, the opening / closing operation of the door 8 is an operation that must be performed when using the washing machine, and the door opening button 56 has a large shape. Therefore, it is required to make it easy to operate and to improve operability by reducing the pressing force.
しかしながら、このような従来の構成では、扉開ボタン５６の位置や開閉操作部材９３の配置や形状は、限られたスペースや位置にコンパクトに構成されており、特に扉開ボタン５６の押圧力は、開閉操作部材９３の回動力、更に係止バネ１１２にて付勢された係止板（係止部材）１１３を回動させる抗力に打ち勝つ押圧力が必要であり、結果として高い荷重の扉開ボタン５６の押圧力が求められていた。 However, in such a conventional configuration, the position of the door opening button 56 and the arrangement and shape of the opening / closing operation member 93 are compactly configured in a limited space and position. In addition, a pressing force that overcomes the rotational force of the opening / closing operation member 93 and the drag force that rotates the locking plate (locking member) 113 biased by the locking spring 112 is required. The pressing force of the button 56 has been demanded.
図６で、扉開ボタン５６から、開閉ロック部５９に与えられる荷重は以下のようになる。扉開ボタン５６の押圧中心と、開閉操作部材９３の作用が平面状同一箇所にあるとして、扉開ボタン５６の押圧中心点Ｍから回動軸５６ａまでの距離をＫとし、開閉操作部材９３の作用中心点から回動支点である回動軸９３ａまでの距離をＣとすると、扉開ボタン５６に加えられたＰの加重が「てこの原理」で、開閉ロック部５９へ作用する荷重Ｑは、それぞれの回転中心と作用点との距離に比例するので、数式１で表せる。 In FIG. 6, the load applied from the door opening button 56 to the opening / closing lock portion 59 is as follows. Assuming that the pressing center of the door opening button 56 and the action of the opening / closing operation member 93 are in the same plane, the distance from the pressing center point M of the door opening button 56 to the rotating shaft 56a is K, and the opening / closing operation member 93 Assuming that the distance from the action center point to the turning shaft 93a, which is the turning fulcrum, is C, the weight of P applied to the door opening button 56 is “leverage principle”, and the load Q acting on the opening / closing lock part 59 is Since it is proportional to the distance between each rotation center and the action point, it can be expressed by Equation 1.
数式１にて、扉体８を開状態にするための開閉ロック部５９へ作用する荷重Ｑは一定として、人の扉開ボタン５６を押圧する操作力Ｐを小さくして操作性を良くするには、Ｋ／Ｊの値を大きくしなければならない。 In Formula 1, the load Q acting on the opening / closing lock part 59 for opening the door body 8 is constant, and the operability is improved by reducing the operating force P pressing the person's door opening button 56. The value of K / J must be increased.
しかしＫの値、即ち扉開ボタン５６の押圧中心点Ｍから回動軸５６ａまでの距離を大きくする事は、図６の平面図でも明らかなように、回動軸５６ａから洗濯機筐体２の外郭線７０までの距離Ｎは、余裕があるとはいえない。またＪを小さい寸法に設定する事は、開閉操作部材９３の形状を極めて小型部材で製作しなければならず、寸法Ｊのバラツキが開閉ロック部５９へ作用する荷重Ｑに大きく影響するので実用的でない。 However, increasing the value of K, that is, the distance from the pressing center point M of the door opening button 56 to the rotation shaft 56a, is evident from the rotation shaft 56a to the washing machine casing 2 as shown in the plan view of FIG. The distance N to the outer contour line 70 cannot be said to have a margin. Setting J to a small dimension is practical because the shape of the opening / closing operation member 93 must be made of an extremely small member, and the variation in the dimension J greatly affects the load Q acting on the opening / closing lock portion 59. Not.
また、扉開ボタン５６の水平回動方向と、開閉操作部材９３の垂直回動方向とは略９０度の動作線のずれがあり、押圧箇所加重の損失が大きくなっていた。 Further, there is a shift of the operation line of about 90 degrees between the horizontal rotation direction of the door opening button 56 and the vertical rotation direction of the opening / closing operation member 93, and the loss of the load on the pressed portion is large.
本発明は、上記従来の課題を解決するもので、扉開ボタンの押圧力を低減し、更に扉開ボタンの形状を大きくして操作性を高めたドラム式洗濯機を提供する事を目的とする。 An object of the present invention is to solve the above-described conventional problems, and to provide a drum type washing machine that reduces the pressing force of the door opening button and further increases the shape of the door opening button to improve operability. To do.
前記従来の課題を解決するために、本発明のドラム式洗濯機は、洗濯機筐体の正面側に配置した洗濯物を出し入れするための前面開口部を開閉自在に覆う略円形の扉体と、この略円形の扉体の外周部であって前記洗濯機筐体に構成したリング状扉枠体と、このリング状扉枠体の外周部上方かつ前記リング状扉枠体の上部切欠け部内に回動可能に配置されるとともに扉体外周の円周方向に沿って長手形状を有する扉開ボタンと、前記扉開ボタンの押圧操作により回動する開閉操作部材と、前記開閉操作部材の動作に連動する扉体の開閉ロック部とを備え、前記扉開ボタンの回動軸は、前記開閉操作部材の回動軸に対して傾斜させて、前記扉開ボタンの回動軸の垂直２等分線が前記扉体の中心に向うように配置させたものである。 In order to solve the above-described conventional problems, a drum-type washing machine of the present invention includes a substantially circular door body that covers a front opening for opening and closing a laundry disposed on the front side of a washing machine casing. A ring-shaped door frame configured in the washing machine casing at an outer peripheral portion of the substantially circular door body, and above the outer peripheral portion of the ring-shaped door frame body and in an upper cutout portion of the ring-shaped door frame body A door opening button that is arranged in a rotatable manner along the circumferential direction of the outer periphery of the door body, an opening / closing operation member that is rotated by a pressing operation of the door opening button, and an operation of the opening / closing operation member An opening / closing lock portion of the door body that is interlocked with the door opening button, and the rotation axis of the door opening button is inclined with respect to the rotation axis of the opening / closing operation member so that it is perpendicular to the rotation axis of the door opening button, etc. The dividing line is arranged so as to face the center of the door body.
これによって、扉開ボタンからの押圧力が小さくとも開閉操作部材を介して開閉ロック部への必要な荷重が確保され、扉開ボタンの操作性が向上する。 Thereby, even if the pressing force from the door opening button is small, a necessary load is secured to the opening / closing lock portion via the opening / closing operation member, and the operability of the door opening button is improved.
本発明のドラム式洗濯機は、扉開ボタンの大型化が可能となり、扉開ボタンの操作力が低減できる。 In the drum type washing machine of the present invention, the door opening button can be enlarged, and the operation force of the door opening button can be reduced.
第１の発明は、洗濯物を収容して回転駆動される洗濯兼脱水槽を収容した洗濯機筐体と、前記洗濯機筐体の正面側に配置した洗濯物を出し入れするための前面開口部を開閉自在に覆う略円形の扉体と、この略円形の扉体の外周部であって前記洗濯機筐体に構成したリング状扉枠体と、このリング状扉枠体の外周部上方かつ前記リング状扉枠体の上部切欠け部内に回動可能に配置されるとともに扉体外周の円周方向に沿って長手形状を有する扉開ボタンと、前記扉開ボタンの押圧操作により回動する開閉操作部材と、前記開閉操作部材の動作に連動する扉体の開閉ロック部とを備え、前記扉開ボタンの回動軸は、前記開閉操作部材の回動軸に対して傾斜させて、前記扉開ボタンの回動軸の垂直２等分線が前記扉体の中心に向うように配置させたことにより、扉開ボタンの押圧中心である作用点と回動軸との寸法の拡大が可能となり、扉開ボタンからの押圧力が小さくとも開閉操作部材を介して開閉ロック部への必要な荷重が確保され、また、扉開ボタンの回動軸中心線が、開閉操作部材の回動軸中心線とは、従来例の略９０度に較べ、所定角度だけ傾斜した構成となり加重の損失が低減するので、扉開ボタンの操作性が向上し、扉開ボタンの形状を容易に大型化できるので、操作性が向上する。 A first aspect of the present invention is a washing machine housing that houses a laundry and dewatering tub that is rotationally driven and contains laundry, and a front opening for taking in and out the laundry disposed on the front side of the washing machine housing A substantially circular door body that can be freely opened and closed, a ring-shaped door frame body that is an outer peripheral portion of the substantially circular door body and is configured in the washing machine casing, and an upper portion of the outer periphery of the ring-shaped door frame body; A door opening button that is rotatably disposed in the upper notch portion of the ring-shaped door frame body and has a longitudinal shape along the circumferential direction of the outer periphery of the door body, and is rotated by a pressing operation of the door opening button. An opening / closing operation member, and an opening / closing lock portion of the door body interlocking with the operation of the opening / closing operation member, wherein the rotation axis of the door opening button is inclined with respect to the rotation axis of the opening / closing operation member, vertical bisector of the pivoting axis of the door opening button is disposed so as toward the center of the door body Therefore, it is possible to increase the size of the action point which is the pressing center of the door opening button and the rotation shaft, and the necessary load to the opening / closing lock part via the opening / closing operation member even if the pressing force from the door opening button is small. In addition, the rotation axis center line of the door opening button is inclined at a predetermined angle from the rotation axis center line of the opening / closing operation member, compared to approximately 90 degrees of the conventional example, thereby reducing weight loss. Therefore, the operability of the door opening button is improved, and the shape of the door opening button can be easily increased in size, so that the operability is improved.
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。なお、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. Note that the present invention is not limited to the embodiments.

図１は、本発明の実施の形態におけるドラム式洗濯機の外観図を示すもので、洗濯機筐体２０２の正面側上部には上向き傾斜面２０２ａが形成され、この傾斜面２０２ａに開閉自在に略円形の扉体２０８が設けられ、前記扉体２０８は、傾斜面２０２ａに配設された扉開ボタン２５６を押圧することによって、洗濯機筐体２０２の傾斜面２０２ａ内部に構成した（点線で示した）開閉ロック部２５９のロック状態を解除して開き、内部の洗濯兼脱水槽２０５への衣類の出し入れを行うことができる。
(Embodiment 1)
FIG. 1 is an external view of a drum-type washing machine according to an embodiment of the present invention. An upwardly inclined surface 202a is formed at the upper part on the front side of the washing machine housing 202, and the inclined surface 202a can be freely opened and closed. A substantially circular door body 208 is provided, and the door body 208 is configured inside the inclined surface 202a of the washing machine housing 202 by pressing a door opening button 256 disposed on the inclined surface 202a (indicated by a dotted line). The open / close lock portion 259 is unlocked and opened, and clothes can be taken in and out of the washing and dewatering tub 205 inside.
前記扉開ボタン２５６の配置は、扉体２０８の外周部に構成したリング状扉枠体２０９の、傾斜面２０２ａ面側から見て右上方向の位置に配し、かつ、扉開ボタン２５６の形状を前記リング状扉枠体２０９の円周方向に長手形状に幅広形成に構成する。 The door opening button 256 is arranged at a position in the upper right direction of the ring-shaped door frame body 209 formed on the outer peripheral portion of the door body 208 when viewed from the inclined surface 202a surface side, and the shape of the door opening button 256 is arranged. The ring-shaped door frame body 209 is formed to have a long and long shape in the circumferential direction.
図２は、図１の扉体２０８を開いて、扉開ボタン２５６および開閉ロック部２５９近傍
の部分詳細平面図を示すものである。図２において、扉開ボタン２５６を押圧すれば、扉開ボタンの回動軸２５６ａを中心に回動し、図２で紙面の下方の開閉操作部材２９３を連動させ、開閉操作部材２９３もまた開閉操作部材の回動軸２９３ａを中心に回動し、係合スプリング２６９を介して開閉ロック部２５９を操作する。
FIG. 2 is a partial detailed plan view of the vicinity of the door opening button 256 and the opening / closing lock portion 259 when the door 208 of FIG. 1 is opened. In FIG. 2, when the door opening button 256 is pressed, the door opening button 256 is rotated around the rotation axis 256a of the door opening button, and the opening / closing operation member 293 below the paper surface in FIG. The operation member rotates about the rotation shaft 293 a and operates the open / close lock portion 259 via the engagement spring 269.
図２において、扉開ボタン２５６の押圧中心点Ｍから扉開ボタンの回動軸２５６ａまでの距離をＥとする。そして、上記扉開ボタン２５６の押圧中心である作用点Ｍから扉開ボタンの回動軸２５６ａの軸線に下ろした垂線、即ち回動軸の垂線Ｈは、扉体２０８の中心に向かうように構成している。即ち扉開ボタンの回動軸２５６ａ中心線は、開閉操作部材の回動軸２９３ａ中心線とは、従来例の略９０度に較べ、角度Ｒだけ傾斜した構成となり加重の損失が低減する。 In FIG. 2, the distance from the pressing center point M of the door opening button 256 to the rotation shaft 256a of the door opening button is E. The perpendicular line drawn to the axis of the pivot shaft 256a of the door opening button action point M is the push center of the door opening button 256, i.e. vertical line H of the pivot axis, as toward the center of the door 208 It is composed. That is, the rotation axis 256a center line of the door opening button is inclined by an angle R as compared with the rotation axis 293a center line of the opening / closing operation member, which is approximately 90 degrees of the conventional example, and the loss of weight is reduced.
図３は、扉開ボタン部の分解矢視図で、扉開ボタン２５６と開閉操作部材２９３との角度の相関関連を説明するものである。図３において、扉開ボタン２５６は、リング状扉枠体２０９の切欠け部２０９ａ内に回動可能に収納され、下方に開閉操作部材２９３を配し、扉開ボタン２５６の回動動作を開閉操作部材２９３の回動に連動させる。 FIG. 3 is an exploded view of the door opening button portion and explains the correlation between the angles of the door opening button 256 and the opening / closing operation member 293. In FIG. 3, the door opening button 256 is rotatably housed in the cutout portion 209 a of the ring-shaped door frame body 209, and an opening / closing operation member 293 is arranged below to open and close the rotation operation of the door opening button 256. The operation member 293 is interlocked with the rotation.
ここで、略水平方向の開閉操作部材の回動軸２９３ａ中心線に対し、扉開ボタンの回動軸２５６ａ中心線の垂線Ｈは、角度Ｒだけ傾斜させている。 Here, with respect to rotation axis 293a centerline of a substantially horizontal opening and closing member, vertical line H of the pivot shaft 256a centerline of door opening button is inclined by an angle R.
一方、図２において、開閉操作部材２９３の作用中心点から回動支点である開閉操作部材の回動軸２９３ａまでの距離は、従来例と同寸法設定としＪとする。 On the other hand, in FIG. 2, the distance from the center of action of the opening / closing operation member 293 to the rotation shaft 293a of the opening / closing operation member, which is a rotation fulcrum, is set to the same size as that of the conventional example, and J.
扉開ボタン２５６に加えられたＰの加重が「てこの原理」で、開閉ロック部２５９へ作用する荷重Ｑは以下の数式２ようになる。 The weight of P applied to the door opening button 256 is “lever principle”, and the load Q acting on the opening / closing lock portion 259 is expressed by the following formula 2.
扉開ボタン２５６の押圧中心点Ｍから扉開ボタンの回動軸２５６ａまでの距離をＥは、数式３のようになり、扉開ボタン２５６を、リング状扉枠体２０９の円周方向に配置したので、扉開ボタンの回動軸２５６ａと、洗濯機筐体２０２の外郭線２７０までの距離Ｆにスペース的な余裕が生じ、Ｋの値より大きく設定が可能となる。 The distance E from the pressing center point M of the door opening button 256 to the rotation axis 256a of the door opening button is expressed by Equation 3, and the door opening button 256 is arranged in the circumferential direction of the ring-shaped door frame 209. As a result, there is a space in the distance F from the rotation axis 256a of the door opening button to the outline line 270 of the washing machine casing 202, and a setting larger than the value of K is possible.
従って、開閉ロック部２５９へ作用する荷重Ｑを変化させる事無く、使用者が扉開ボタン２５６に加える加重Ｐの値を低減できる。 Therefore, the value of the weight P applied to the door opening button 256 by the user can be reduced without changing the load Q acting on the opening / closing lock portion 259.
さらに扉開ボタン２５６は、リング状扉枠体２０９の円周方向に長手形状に幅広形状をしているが、扉開ボタンの回動軸２５６ａの垂線を扉体の中心に向けたので、人が押圧中心点Ｍではなく端部を押しても距離Ｅは変化しない。よって扉開ボタンを幅広にしても加重Ｐは安定する。 Further door opening button 256, since although the broad shape elongated shape in the circumferential direction of the ring-shaped door frame 209, toward the vertical line of the pivot shaft 256a of the door opening button in the center of the door body, The distance E does not change even if a person presses the end instead of the pressing center point M. Therefore, even if the door opening button is wide, the weight P is stabilized.
以上のように構成されたドラム式洗濯機について、以下その動作、作用を説明する。 About the drum type washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
まず、扉開ボタン２５６の位置を、リング状扉枠体２０９の円周方向に長手形状に幅広形状に構成し、かつ扉開ボタンの回動軸２５６ａの垂線を扉体の中心に向けたので、大型化が可能となり、かつボタン操作性が向上する。 First, the position of the door opening button 256, configured wider shape elongated shape in the circumferential direction of the ring-shaped door frame 209, and directed toward the vertical line of the pivot shaft 256a of the door opening button in the center of the door body Therefore, the size can be increased and the operability of the button is improved.
また、扉開ボタン２５６の配置を従来例に比べ、洗濯機内方に位置できたので、洗濯機筐体２０２の外郭線２７０までの距離Ｆにスペース的な余裕が生じて、押圧中心点Ｍから扉開ボタンの回動軸２５６ａまでの余裕距離Ｅを大きく設定でき、扉開ボタン２５６への押圧力が小さく出来、操作性を向上できる。 Further, since the arrangement of the door opening button 256 can be located inward of the washing machine as compared with the conventional example, a space margin is generated in the distance F to the outer line 270 of the washing machine casing 202, and from the pressing center point M, The margin distance E to the rotation axis 256a of the door opening button can be set large, the pressing force to the door opening button 256 can be reduced, and the operability can be improved.
扉開ボタン２５６の構成を、リング状扉枠体２０９の円周方向に構成したので、デザイン変更などで、扉開ボタン２５６の外形形状を変更した場合など、小型部材のリング状扉枠体２０９の形状の扉開ボタン２５６対応箇所を変更することで対処が可能となり、大型部材である洗濯機筐体２０２の正面側上部の上向き傾斜面２０２ａの変更を必要としなくなり、デザインの多様化に対応が可能となる。 Since the configuration of the door opening button 256 is configured in the circumferential direction of the ring-shaped door frame body 209, when the outer shape of the door opening button 256 is changed due to a design change or the like, the ring-shaped door frame body 209 is a small member. Can be dealt with by changing the location corresponding to the door opening button 256 of the shape, and it is not necessary to change the upward inclined surface 202a of the upper part of the front side of the washing machine housing 202, which is a large member, and supports diversification of design Is possible.
以上のように、本実施の形態においては、扉開ボタンの大型化が可能となり、扉開ボタンの押圧力が小さく出来、操作性を向上できる。 As described above, in the present embodiment, the door opening button can be increased in size, the pressing force of the door opening button can be reduced, and the operability can be improved.
以上のように、本発明にかかるドラム式洗濯機は、扉開ボタンの大型化が可能となり、扉開ボタンの押圧力が小さく出来、操作性を向上できるので、扉体のロック機構を有するドラム式乾燥機等の用途にも適用できる。 As described above, in the drum type washing machine according to the present invention, the door opening button can be increased in size, the pressing force of the door opening button can be reduced, and the operability can be improved. It can also be applied to uses such as a dryer.
