Description

本発明は、回転駆動される洗濯兼脱水槽を内包した水槽を洗濯機筐体内に収容して前記水槽内への給水、排水及び洗濯兼脱水槽の回転を制御して洗濯、すすぎ、脱水の各工程を実施する洗濯機に関するものである。   The present invention accommodates a water tub containing a rotationally driven washing and dewatering tub in a washing machine casing and controls the water supply, drainage, and rotation of the washing and dewatering tub into the water tub for washing, rinsing and dewatering. The present invention relates to a washing machine that performs each process.

例えば、洗濯兼脱水槽を水平配置したドラム式洗濯機においては、回転駆動される洗濯兼脱水槽に対して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。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。   For example, in a drum-type washing machine in which a washing and dewatering tub is horizontally arranged, an opening for taking in and out the laundry is formed on the front side of the washing machine housing with respect to the rotationally driven washing and dewatering tub. It can be closed freely. 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 configured so that it can be avoided.

このような扉体の開閉を操作するために、機械的な構造と電気的な構造とを組み合わせた開閉操作構造が設けられ、ドラム式洗濯機の運転停止状態あるいは運転状態に応じて扉体の開閉が制御される。この制御はドラム式洗濯機の運転を制御する制御動作に対応して実行される必要があるため、洗濯兼脱水槽の回転が完全に停止するまでの遅延時間を設けたり、運転状態に応じた扉体のロック解除を設けた構成などが実施されている。   In order to operate the opening and closing of the door body, an opening / closing operation structure combining a mechanical structure and an electrical structure is provided, and the door body is operated depending on whether the drum-type washing machine is stopped or operating. Opening and closing is controlled. Since this control needs to be executed in response to the control operation for controlling the operation of the drum type washing machine, a delay time until the rotation of the washing and dewatering tub completely stops or according to the operation state The structure etc. which provided the lock release of the door body are implemented.

例えば、扉体の閉成により扉体のフックが係合することで摺動部材を摺動移動させ、この摺動部材の移動によりスイッチ手段に通電制御して、通電動作により駆動手段を動作させ、駆動手段の動作によりフックが外れない状態に保持手段により摺動部材を保持する構造が知られている。この構造により、扉体を閉じて運転開始するまでの時間を短縮して確実にロックすることができ、全ての運転が終了してから扉体の開放を可能とするまでの時間を短縮させている（特許文献１参照）。
特開平１０−２７２２９３号公報（第２〜４頁、図１） For example, when the door body is closed, the sliding member is slid by the engagement of the hook of the door body, the switch means is energized by the movement of the sliding member, and the drive means is operated by the energization operation. A structure is known in which the sliding member is held by the holding means in a state where the hook is not removed by the operation of the driving means. With this structure, it is possible to reduce the time until the door body is closed and to start operation, and to lock it securely, and to shorten the time until the door body can be opened after all operations are completed. (See Patent Document 1).
Japanese Patent Laid-Open No. 10-272293 (pages 2 to 4, FIG. 1)

従来技術に係る扉体の開閉操作構造では電気的な動作部分が多く、全体構造が複雑になるため水を取り扱う洗濯機として故障や異常発生の恐れがあり、信頼性に欠ける課題があった。洗濯機の扉体開閉操作構造としては、より簡易な構造でより確実な開閉操作がなされるように構成することが要求されており、取扱方法に反する使用者の操作によっても故障を発生させない構造が望まれている。   In the door opening and closing operation structure according to the prior art, there are many electrical operation parts, and the entire structure is complicated, so that there is a risk of failure or abnormality as a washing machine that handles water, and there is a problem of lack of reliability. As a door opening / closing operation structure of a washing machine, it is required to be configured so that a more reliable opening / closing operation can be performed with a simpler structure, and a structure that does not cause a failure even by a user operation contrary to the handling method. Is desired.

本発明が目的とするところは、運転状態に対応する扉体の開閉操作を制御すると共に、誤った操作に伴う異常を防止する扉体の開閉操作構造を備えた洗濯機を提供することにある。   An object of the present invention is to provide a washing machine having a door body opening / closing operation structure that controls an opening / closing operation of a door body corresponding to a driving state and prevents an abnormality associated with an erroneous operation. .

上記目的を達成するための本発明は、洗濯物を収容して回転駆動される洗濯兼脱水槽を内包した水槽を洗濯機筐体内に収容して前記水槽内への給水、排水及び前記洗濯兼脱水槽の回転を制御して洗濯、すすぎ、脱水の各工程を実施する洗濯機において、前記洗濯機筐体の正面側に形成されて前記洗濯兼脱水槽に対して洗濯物を出し入れするための開口部を開閉自在に覆いラッチが内側に突設された扉体と、前記洗濯機筐体の正面側に設けられ前記扉体を開くための扉開ボタンと、前記扉体を閉じたときに前記ラッチが入り込むラッチ受を有する開閉ロック部とを備え、前記開閉ロック部は、前記扉体を閉じたときに前記ラッチ受に入り込んだ前記ラッチに係止することで前記蓋体を閉じた状態に係止する係止部材と、前記係止部材を前記ラッチに係止する方向に付勢する第１付勢手段と、前記第１付勢手段の付勢に抗して進出移動することで前記係止部材を前記ラッチに係止した状態から外れた状態に移動させる引張りピンと、前記係止部材を前記ラッチに係止した状態にロックするロック手段とにより構成され、前記扉開ボタンと前記開閉ロック部との間には、回動軸を有し前記扉開ボタンの押圧操作により前記回動軸を回動支点として回動する開閉操作部材と、一端が前記開閉操作部材に係合し他端が前記引張りピンに連結された第２付勢手段と、前記扉開ボタンと前記開閉操作部材の間に取り付けられ前記扉開ボタンを押上げ方向に付勢する第３付勢手段とが設けられ、前記ロック手段が前記係止部材をロックしていない状態においては、前記扉開ボタンの押圧操作がなされると、前記第３付勢手段の付勢に抗して前記扉開ボタンが前記開閉操作部材を押すことで前記開閉操作部材が回動し、前記開閉操作部材の回動に伴い前記第２付勢手段は変形することなく前記第１付勢手段の付勢に抗して引張りピンが進出移動することで前記係止部材が前記ラッチに係止した状態から外れた状態に移動し、前記ロック手段が前記係止部材をロックしている状態においては、前記扉開ボタンの押圧操作がなされると、前記第３付勢手段の付勢に抗して前記扉開ボタンが前記開閉操作部材を押すことで前記開閉操作部材が回動し、前記開閉操作部材の回動に伴い前記第２付勢手段が変形するようにしたことを特徴とする。 In order to achieve the above object, the present invention provides a water tub containing a washing and dewatering tub which accommodates laundry and is driven to rotate in a washing machine casing to supply water to the water tub, drain water, and the washing and washing tub. In a washing machine that controls the rotation of the dewatering tub to perform washing, rinsing, and dewatering steps, the washing machine is formed on the front side of the washing machine housing and is used to put laundry in and out of the washing and dewatering tub a latch brewing covering an opening openably is projected inside the door body, a door opening button for provided on the front side of the washing machine casing opening the door body, when closing the door body And an open / close lock portion having a latch receiver into which the latch enters, and the open / close lock portion is engaged with the latch received in the latch receiver when the door body is closed to close the lid body. a locking member for locking the state, the engaging member and the rack State in which the first biasing means for biasing in the direction of locking, the locking member by advancing moves against the bias of said first biasing means deviates from the state engaged with the latch in And a locking means for locking the locking member in a state where the locking member is locked to the latch. Between the door opening button and the opening / closing locking portion, a rotation shaft is provided. and opening and closing operation member rotates as the rotation fulcrum the pivot shaft by the pressing operation of door opening button, and the second biasing means having one end engages with the other end to the opening and closing operation member connected to said tensioning pin A third urging means attached between the door opening button and the opening / closing operation member for urging the door opening button in the push-up direction, and the locking means does not lock the locking member; In the state, the door opening button is pressed. When the third biasing means against the bias of the aforementioned opening and closing operation member pivoted by the door opening button pushes the opening and closing operation member, the opening and closing operation the biasing second with the rotation of the member The biasing means moves without being deformed, so that the pulling pin advances and moves against the biasing force of the first biasing means, so that the locking member moves from the locked state to the latched state. In a state where the means locks the locking member, when the door opening button is pressed, the door opening button moves the opening / closing operation member against the urging force of the third urging means. The opening / closing operation member is rotated by pushing, and the second urging means is deformed with the rotation of the opening / closing operation member .

上記構成によれば、洗濯物を洗濯兼脱水槽に対して出し入れするために、開口部を閉じた状態にある扉体を開くときには、扉開ボタンを押圧操作すると、第２付勢手段を通じて係止部材に係合されて第１付勢手段の付勢により進出方向にある開閉操作部材は付勢に抗して後退するので、第２付勢手段を通じて係止部材が係止解除方向に移動して扉体の係止が解除されて扉体が開かれる。この扉体を開く操作は機械的な動作によってなされるので、洗濯機の電源がオフの状態であっても実行することができる。このとき、運転停止状態で扉体を開くために扉開ボタンが押圧操作されたときには、第２付勢手段は開閉操作部材の動きを係止部材に伝える連結部材として作用すればよいので変位する必要はなく、扉開ボタンの押圧操作を速やかに係止部材に伝達することができる。洗濯機が運転状態にあるときには、扉体が開かれると回転する洗濯兼脱水槽に触れる危険性や水が飛散するなどの障害があるので、扉体を開くことができないようにロック手段により係止部材の動きはロックされる。このロック中に扉開ボタンが押圧操作されると、係止部材がロックされているため開閉操作部材が回動しても扉体は開かず、扉体操作部材の後退移動は第２付勢手段が変形することで吸収される。従って、扉開ボタンを押圧操作した使用者には第２付勢手段を無理に変形させた違和感のある感触が伝わり、開閉操作部材や係止部材が無理な押圧操作で破壊されることも第２付勢手段の変形により保護される。また、第３付勢手段の付勢に抗して押圧操作のストロークが所定距離以上になって開閉操作部材に押圧が及ぶように形成することにより、扉開ボタンに適切な押圧感を与えると同時に、洗濯機の運転に伴う振動により扉開ボタンが微振動して異音が発生する状態になることを防止できる。 According to the above configuration, when opening the door with the opening closed in order to put the laundry in and out of the washing and dewatering tub, when the door opening button is pressed, the door is engaged through the second urging means. Since the opening / closing operation member that is engaged with the stop member and is in the advancing direction by the urging of the first urging means moves backward against the urging, the engaging member moves in the unlocking direction through the second urging means. Then, the door body is unlocked and the door body is opened. Since the operation of opening the door body is performed by a mechanical operation, it can be executed even when the power of the washing machine is off. At this time, when the door opening button is pressed to open the door body in the operation stop state, the second urging means is displaced because it only has to act as a connecting member that transmits the movement of the opening / closing operation member to the locking member. There is no need, and the pressing operation of the door opening button can be quickly transmitted to the locking member. When the washing machine is in operation, there is a risk of touching the rotating washing and dewatering tub when the door is opened, and there are obstacles such as water splashing. The movement of the stop member is locked. When the door opening button is pressed during the locking, the locking member is locked, so that the door body does not open even when the opening / closing operation member rotates, and the backward movement of the door body operating member is the second urging force. It is absorbed by the deformation of the means. Accordingly, the user who presses the door opening button is given an uncomfortable feeling by forcibly deforming the second urging means, and the opening / closing operation member and the locking member may be destroyed by the excessive pressing operation. 2 Protected by deformation of the biasing means. Further , by forming the stroke of the pressing operation to be greater than a predetermined distance against the urging force of the third urging means so that the opening / closing operation member is pressed, an appropriate pressing feeling is given to the door opening button. At the same time, it can be prevented that the door opening button slightly vibrates due to vibration associated with the operation of the washing machine and an abnormal noise is generated.

本発明によれば、洗濯機の状態に応じて扉体の開閉を係止又は係止解除することができ、逆に扉体の状態に応じて洗濯機の動作を制御することができる。また、扉開ボタンの押圧操作を第２付勢手段を通じて係止部材に伝えるので、扉を開く操作を行うときには第２付勢手段は変位せず係止部材に円滑に操作動作が伝達され、係止部材がロックされているときには無理な押圧圧力を第２付勢手段の変位により吸収することができる。また、開閉操作部材や係止部材が無理な押圧操作で破壊されることも防止できる。さらに、扉開ボタンに適切な押圧感を与えると同時に、洗濯機の運転に伴う振動により扉開ボタンが微振動して異音が発生する状態になることを防止できる。 According to the present invention, the opening and closing of the door body can be locked or unlocked according to the state of the washing machine, and conversely, the operation of the washing machine can be controlled according to the state of the door body. Further, since the pressing operation of the door opening button is transmitted to the locking member through the second biasing means, when performing the operation of opening the door, the second biasing means is not displaced and the operation operation is smoothly transmitted to the locking member, When the locking member is locked, an unreasonable pressing pressure can be absorbed by the displacement of the second urging means. Further , it is possible to prevent the opening / closing operation member and the locking member from being destroyed by an excessive pressing operation. Furthermore, an appropriate pressing feeling can be given to the door opening button, and at the same time, it can be prevented that the door opening button slightly vibrates due to vibration associated with the operation of the washing machine and an abnormal sound is generated.

ここでは、洗濯兼脱水槽を傾斜配置したドラム式洗濯機を用いて、詳細を説明する。図１は、実施形態に係るドラム式洗濯機１の外観を示すもので、洗濯機筐体２の正面側上部には上向き傾斜面２ａが形成され、この傾斜面２ａに形成された円形の開口部を開閉自在に閉じる円形の扉体８が設けられている。図２に示すように、洗濯機筐体２内には有底円筒状に形成された水槽３内に駆動モータ４によって回転駆動される有底円筒形の洗濯兼脱水槽５を配した水槽ユニット１０が配設され、この水槽ユニット１０は、図示しないサスペンション構造によって洗濯兼脱水槽５の回転軸方向Ｒが正面側から底面となる背面側に向けて水平方向Ｈから角度θで下向き傾斜となるように支持されている。水槽ユニット１０が洗濯機筐体２内に傾斜配置されることにより、水槽３及び洗濯兼脱水槽５の開口部は前記傾斜面２ａに対向した状態になるので、傾斜面２ａに設けられた扉体８を開くと、洗濯兼脱水槽５に対して洗濯物を出し入れすることができる。扉体８は上向き傾斜面２ａに設けられているので、洗濯兼脱水槽５に対する洗濯物の出し入れする作業に際して腰を屈める具合が少なくてすみ、また、ドラム式洗濯機１の正面側に余裕のある空間を確保する必要もないので、洗面所などの狭い空間にも設置可能で作業性のよいドラム式洗濯機１に構成することができる。また、扉体８の中央部位は透明体によって形成されているので、洗濯、すすぎ、脱水の各工程の運転状態を腰を屈めることなく観察することができる。   Here, the details will be described using a drum-type washing machine in which washing and dewatering tubs are arranged at an inclination. FIG. 1 shows an external appearance of a drum-type washing machine 1 according to the embodiment, and an upward inclined surface 2a is formed on the front side upper portion of the washing machine casing 2, and a circular opening formed in the inclined surface 2a. A circular door body 8 that closes and opens the part is provided. As shown in FIG. 2, a water tub unit in which a bottomed cylindrical washing and dewatering tub 5 that is rotationally driven by a drive motor 4 is arranged in a water tub 3 formed in a bottomed cylindrical shape in a washing machine casing 2. 10, the water tank unit 10 is inclined downward at an angle θ from the horizontal direction H from the front side to the back side, which is the bottom surface, due to the suspension structure (not shown). So that it is supported. Since the water tank unit 10 is inclined in the washing machine casing 2, the openings of the water tank 3 and the washing and dewatering tank 5 are in a state of facing the inclined surface 2a, and therefore the door provided on the inclined surface 2a. When the body 8 is opened, the laundry can be taken in and out of the washing and dewatering tub 5. Since the door body 8 is provided on the upward inclined surface 2a, it is possible to reduce the degree of bending when the laundry is put into and out of the washing / dehydrating tub 5, and there is room on the front side of the drum type washing machine 1. Therefore, it is possible to configure the drum-type washing machine 1 which can be installed in a narrow space such as a washroom and has good workability. Moreover, since the center part of the door body 8 is formed with the transparent body, the driving | running state of each process of washing, a rinse, and spin-drying | dehydration can be observed without bending.

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、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は扉閉状態にロックされる。この扉開ボタン５６による扉体８の開閉構造及び扉体８のロック構造について以下に説明する。   The door body 8 can be opened by pressing a door opening button 56 disposed on the inclined surface 2a, the laundry is put into the washing and dehydrating tub 5, the door body 8 is closed and the operation is started. Then, the door body 8 is locked in the door closed state. The opening / closing structure of the door body 8 by the door opening button 56 and the lock structure of the door body 8 will be described below.

図３は、傾斜面２ａの外装材を取り外した状態を示すもので、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。   FIG. 3 shows a state in which the exterior material of the inclined surface 2a is removed. The door opening button 56 and the opening / closing lock portion 59 are engaged by an engagement spring (second urging means) 69 formed as a tension spring. It is arranged in the state. 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.

図４、図５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り、押圧操作されると押上バネ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。係合スプリング６９の変位強度は、圧縮バネとして形成された前記押上バネ９２や、後述する圧縮バネとして形成された係止バネ（第１付勢手段）１１２の変位強度より格段に大きく設定されており、この扉体８を開く操作による引張り力によって変位することはない。   As shown in FIGS. 4 and 5, the door opening button 56 is held so as to be able to rotate within a restricted range by a rotating shaft 56a, and is normally a push-up spring (third biasing means) attached inside. Reference numeral 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. When the pushing operation is performed, the pushing spring 92 is compressed and the pushing spring 92 is compressed. The pressing protrusion 94 provided in contact with the opening / closing operation member 93 rotates the opening / closing operation member 93 with the rotation shaft 93a as a rotation fulcrum, so that the engagement spring 69 whose one end engages with the opening / closing operation member 93. Exerts a pulling force on The displacement strength of the engagement spring 69 is set to be much larger than the displacement strength of the push-up spring 92 formed as a compression spring and a locking spring (first urging means) 112 formed as a compression spring described later. Therefore, the door body 8 is not displaced by a pulling force generated by opening the door body 8.

図６に示すように、開閉操作部材９３の回動により係合スプリング６９が引かれると、係合スプリング６９の他端が係合する引張りピン１１１が係止バネ１１２の付勢に抗して進出移動し、係止板（係止部材）１１３を支軸１１４を回動支点として回動させるので、図８に示すように、ラッチ受９１に嵌り込んでいたラッチ９０のロック穴９０ａに嵌入している係止板１１３の突起部１１３ａが引き戻されてロック穴９０ａから外れるので、扉体８は図示しないバネ付勢により開かれる。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、押圧突起９４は扉開ボタン５６を押し上げ、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。   As shown in FIG. 6, when the engagement spring 69 is pulled by the rotation of the opening / closing operation member 93, the pulling pin 111 engaged with the other end of the engagement spring 69 resists the bias of the locking spring 112. Since the advancing movement is performed and the locking plate (locking member) 113 is rotated with the support shaft 114 as a rotation fulcrum, it is inserted into the lock hole 90a of the latch 90 that has been fitted into the latch receiver 91 as shown in FIG. Since the protruding portion 113a of the locking plate 113 is pulled back and disengaged from the lock hole 90a, the door body 8 is opened by a spring bias (not shown). 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, the pressing projection 94 pushes up the door opening button 56, and the urging of the lifting spring 92 works to return the door opening button 56 to its original position. To do.

扉体８を閉じる操作が行われると、ラッチ受９１に嵌まり込むラッチ９０の先端により突起部１１３ａはその先端の傾斜面が押圧される結果、係止板１１３を係止バネ１１２の付勢に抗して回動させ、ラッチ９０がラッチ受９１内に完全に入り込むと、突起部１１３ａがロック穴９０ａに入り込める状態になるので、係止バネ１１２の付勢を受ける係止板１１３が回動して、その突起部１１３ａをラッチ９０のロック穴９０ａに嵌入させるため、閉じられた扉体８は閉じた状態に係止される。   When the operation of closing the door body 8 is performed, the protruding portion 113a is pressed by the tip of the latch 90 fitted into the latch receiver 91 and the inclined surface of the tip is pressed, so that the locking plate 113 is urged by the locking spring 112. When the latch 90 completely enters the latch receiver 91, the projection 113a enters the lock hole 90a, so that the locking plate 113 that receives the biasing force of the locking spring 112 rotates. Since the projection 113a is inserted into the lock hole 90a of the latch 90, the closed door body 8 is locked in the closed state.

ドラム式洗濯機１の運転が開始されると、図示しない制御手段により開閉ロック部５９に設けられたソレノイド（ロック手段）１１５に１ショットの通電がなされ、図７に示すように、ロック板（ロック手段）１１６を後退させた後に進出させる動作により、ロックバネ（ロック手段）１１７の作用により先端のロック突起１１６ａが係止板１１３の側面に当接する状態となるので、係止板１１３の回動はロックされ、扉開ボタン５６を押圧しても扉体８は開くことはできない状態になり、洗濯兼脱水槽５が高速回転している脱水運転中などに手が差し込まれる危険性の回避や、運転中に扉体８が開かれて水が外部に飛散することを防止している。   When the operation of the drum-type washing machine 1 is started, the solenoid (locking means) 115 provided in the opening / closing lock part 59 is energized for one shot by a control means (not shown), and as shown in FIG. When the locking means 116 is moved backward and then moved forward, the lock spring (locking means) 117 is brought into contact with the side surface of the locking plate 113 by the action of the lock spring (locking means) 117. Is locked and the door 8 cannot be opened even when the door opening button 56 is pressed, and the danger that the hand is inserted during the dehydration operation in which the washing and dewatering tub 5 is rotating at high speed is avoided. During operation, the door body 8 is opened to prevent water from splashing outside.

また、ドラム式洗濯機１の運転中に扉開ボタン５６を押圧して扉体８を開く操作がなされると、係止板１１３の回動によりマイクロスイッチ（係止解除検出手段）１１８が作動して扉体８の開いた状態が検知され、その検知出力はドラム式洗濯機１の制御手段に入力されるので、洗濯兼脱水槽５の回転が停止した状態になるように制御される。   When the door opening button 56 is pressed to open the door body 8 while the drum type washing machine 1 is in operation, the micro switch (lock release detecting means) 118 is activated by the rotation of the lock plate 113. Then, the open state of the door body 8 is detected, and the detection output is input to the control means of the drum type washing machine 1, so that the rotation of the washing and dewatering tub 5 is controlled to be stopped.

上記構成において、扉開ボタン５６が押圧されない状態においては、扉開ボタン５６は押上バネ９２により上限位置まで付勢された状態となり、開閉操作部材９３は係合スプリング６９を介して係止バネ１１２により付勢され、押上バネ９２により付勢された状態になっているのでガタつきが生じず、扉開ボタン５６に適切な押圧感を与えると同時に、ドラム式洗濯機１の運転に伴う振動により扉開ボタン５６や開閉操作部材９３が微振動して異音が発生する状態になることも防止される。   In the above configuration, when the door opening button 56 is not pressed, the door opening button 56 is urged to the upper limit position by the push-up spring 92, and the opening / closing operation member 93 is engaged via the engagement spring 69. And is not biased by the push-up spring 92, giving an appropriate pressing feeling to the door opening button 56, and at the same time due to vibration accompanying the operation of the drum type washing machine 1. It is also possible to prevent the door opening button 56 and the opening / closing operation member 93 from being vibrated and generating abnormal noise.

また、係合スプリング６９の引張り変位強度は押上バネ９２や係止バネ１１２の圧縮変位強度よりも格段に大きく、扉開ボタン５６が押圧されたときに開閉操作部材９３が回動した引張り力でほとんど変形することなく引張りピン１１１に伝えて係止バネ１１２を圧縮方向に変位させるので、扉開ボタン５６を押圧したストロークが無駄なく係止板１１３に伝達される。   In addition, the tensile displacement strength of the engagement spring 69 is much larger than the compression displacement strength of the push-up spring 92 and the locking spring 112, and is the tensile force that the opening / closing operation member 93 rotates when the door opening button 56 is pressed. Since it is transmitted to the pulling pin 111 with almost no deformation and the locking spring 112 is displaced in the compression direction, the stroke of pressing the door opening button 56 is transmitted to the locking plate 113 without waste.

また、脱水運転中など、係止板１１３がロック板１１６によりロックされた扉体ロック状態で扉開ボタン５６が押圧操作されて扉体８を無理に開こうとする操作がなされたときには、係合スプリング６９には大きな引張り力が加わって変位するので、ロック状態にある係止板１１３に無理な力を及ぼさず、開閉操作部材９３にも無理な力が加わらない。従って、扉開ボタン５６を押圧操作した使用者には大きな変位強度を有する係合スプリング６９を無理に変位させた違和感のある感触が伝わり、開閉操作部材９３や係止板１１３が無理な押圧操作で破壊されることが防止される。   In addition, when the door opening button 56 is pressed and the door body 8 is forcibly opened when the locking plate 113 is locked by the lock plate 116 such as during a dehydrating operation, Since the combined spring 69 is displaced by applying a large tensile force, an unreasonable force is not exerted on the locking plate 113 in the locked state, and an unreasonable force is not exerted on the opening / closing operation member 93. Therefore, the user who presses the door opening button 56 is given an uncomfortable feeling by forcibly displacing the engagement spring 69 having a large displacement strength, and the opening / closing operation member 93 and the locking plate 113 cannot be pressed. Is prevented from being destroyed.

以上説明した実施形態に係るドラム式洗濯機１は、洗濯兼脱水槽５を傾斜配置して洗濯機筐体２の傾斜面２ａに扉体８を設けた構成について説明したが、従来構成のように洗濯兼脱水槽を水平配置して洗濯機筐体の垂直な面に扉体を設けた構成においても、上述した扉体８の開閉操作構造を同様に適用することができる。   In the drum type washing machine 1 according to the embodiment described above, the configuration in which the washing and dewatering tub 5 is inclined and the door body 8 is provided on the inclined surface 2a of the washing machine housing 2 has been described. In the configuration in which the washing and dewatering tub is horizontally arranged and the door is provided on the vertical surface of the washing machine casing, the above-described opening / closing operation structure of the door 8 can be similarly applied.

また、本実施形態に係るドラム式洗濯機１に乾燥機能を設けてドラム式洗濯乾燥機として構成した場合においても、上述した扉体８の開閉構造を適用することができ、乾燥運転の途中で洗濯物を取り出すために扉体８を開くことができるように構成することもできる。この乾燥途中で扉体８を開くことを可能にするためには、乾燥運転中にはソレノイド１１５による係止板１１３のロックが作動しないように制御し、扉体８を開く操作がなされたときには、マイクロスイッチ１１８による扉開動作の検出により洗濯兼脱水槽５の回転を停止する制御により運転中に扉体８が開かれる危険性は回避できる。   Further, even when the drum-type washing machine 1 according to the present embodiment is provided with a drying function and configured as a drum-type washing and drying machine, the above-described opening / closing structure of the door body 8 can be applied, and during the drying operation. The door body 8 can be opened to take out the laundry. In order to make it possible to open the door body 8 during the drying, control is performed so that the locking of the locking plate 113 by the solenoid 115 is not activated during the drying operation, and when the operation of opening the door body 8 is performed. The risk of opening the door body 8 during operation can be avoided by controlling the rotation of the washing / dehydrating tub 5 by detecting the door opening operation by the micro switch 118.

また、洗濯兼脱水槽の内底部にパルセータを有し、扉体を上面に有する全自動洗濯機、洗濯乾燥機においても上述した構造を同様に適用することができる。   The above-described structure can be similarly applied to a fully automatic washing machine and a washing / drying machine having a pulsator at the inner bottom of the washing and dewatering tank and having a door on the upper surface.

以上の説明の通り本発明によれば、洗濯機の状態に応じて扉体の開閉を係止又は係止解除することができ、洗濯兼脱水槽を回転駆動する運転中の洗濯機内に手が差し込まれる危険性が回避され、運転中の洗濯兼脱水槽から水や洗濯物が外部に飛び出すことが防止される。 According to the present invention as explained above, the washing machine state can be locked or unlocking the opening and closing of the door body in response to the hand wash濯兼dehydrating tub in the washing machine during operation for rotating The danger of being inserted is avoided, and water and laundry are prevented from jumping out of the washing / dehydrating tub during operation.
