The water tub is elastically supported via an anti-vibration support device and includes an acceleration sensor for vibration detection in an upper portion on an outside surface of the water tub. When the acceleration sensor detects prescribed vibration through the water tub on the basis of an unbalanced state caused by rotation of the rotary tub, spin-drying operation control is changed and performed based on a detected signal. The acceleration sensor is installed in the water tub at a position at which a minimum gap between the acceleration sensor and the inside surface of the housing is greater than the minimum gap between the outside surface of the water tub and the inside surface of the housing.

Description

本発明の実施形態は、脱水運転可能な洗濯機に関する。   Embodiments described herein relate generally to a washing machine capable of dewatering operation.

従来、脱水運転を行なう洗濯機では、洗濯物を収容した洗濯槽兼脱水槽からなる回転槽を高速回転し遠心脱水するようにしている。その回転槽は、上面を開放した有底筒状をなし縦軸周りに回転する。この回転槽の外周囲に配置された水槽は、同様に有底筒状をなし洗濯機の外郭を形成する筐体内の上部4箇所から垂下された吊り棒とコイルばねとからなる吊り棒装置を介して弾性支持され、もって水槽に生じた振動を緩衝し筐体などへの振動伝達を防止している。   2. Description of the Related Art Conventionally, in a washing machine that performs a dehydration operation, a rotating tub composed of a washing tub and a dewatering tub containing laundry is rotated at high speed to perform centrifugal dehydration. The rotating tank has a bottomed cylindrical shape with an open upper surface and rotates around the vertical axis. The water tank arranged around the outer periphery of the rotating tank is similarly provided with a bottomed cylindrical shape, and a suspension rod device comprising a suspension rod and coil springs suspended from four upper portions in a casing that forms the outline of the washing machine. Through which the vibration generated in the water tank is buffered and vibration transmission to the housing or the like is prevented.

しかしながら、弾性支持された水槽は、特に脱水運転時に生じる洗濯物のアンバランス状態による振動振幅が大きく、例えば外方への揺れが大きい場合には、その外周囲の筐体と衝突したり、或は回転槽が正常な回転速度に達しない回転不足などの不具合を生じる。そこで、この種洗濯機では水槽が所定以上の振動を生じたとき、これを検知して脱水運転の回転速度等を制御してアンバランス状態を是正し、更なる異常振動に発展するのを未然に防止するようにしている。   However, the elastically supported water tank has a large vibration amplitude due to the unbalanced state of the laundry that occurs particularly during the dehydration operation. For example, when the outward shaking is large, the water tank may collide with the outer surrounding casing, or Causes problems such as insufficient rotation that the rotating tank does not reach the normal rotation speed. Therefore, in this type of washing machine, when the water tank generates vibrations exceeding a predetermined level, this is detected and the rotational speed of the dehydrating operation is controlled to correct the unbalanced state and develop into further abnormal vibration. Try to prevent.

その基本的な振動検知手段としては、水槽の側壁と所定距離を置いて垂下する安全レバーを設け、該レバーに水槽が当接することによる機械的変位に基づき振動検知可能としている。ただし、この検知手段では振動方向に制約を受けたり、主たる振動要因であるアンバランス量などを正確に検知できない点で不利である。そのため、振動検知を電気信号に変換する加速度センサを水槽側壁に設け、これら二つの振動検知手段を有効活用した提案がなされている(例えば、特許文献1参照)。   As its basic vibration detection means, a safety lever that is suspended at a predetermined distance from the side wall of the water tank is provided, and vibration detection is possible based on mechanical displacement caused by the water tank coming into contact with the lever. However, this detection means is disadvantageous in that it is restricted by the vibration direction and cannot accurately detect an unbalance amount that is a main vibration factor. Therefore, an acceleration sensor that converts vibration detection into an electrical signal is provided on the side wall of the water tank, and proposals have been made that effectively use these two vibration detection means (for example, see Patent Document 1).

特開平10−43469号公報Japanese Patent Laid-Open No. 10-43469

そこで、加速度センサを水槽の適正位置に取付固定することで、加速度センサを衝突などから保護するとともに、確実な振動検知ができてアンバランス状態を是正するなどの的確な防振制御が可能となり、延いては洗濯機のコンパクト化も期待できる洗濯機を提供する。   Therefore, by attaching and fixing the acceleration sensor at the appropriate position in the water tank, it is possible to protect the acceleration sensor from collisions, etc., and to perform accurate vibration control such as correct vibration detection and correction of unbalanced state, In addition, we will provide a washing machine that can be expected to be compact.

本実施形態の洗濯機によれば、筐体内に、縦軸周りに回転し脱水運転を可能とする有底円筒状の回転槽、および該回転槽を内包して設けた有底円筒状の水槽を有する。水槽は防振支持装置を介して弾性的に支持され、該水槽の外側面上部に振動検知用の加速度センサを備える。回転槽の回転に伴うアンバランス状態に基づき加速度センサが水槽を介して所定の振動を検知したとき、該検知信号に基づき脱水運転制御を変更して実行するものにあって、加速度センサの水槽への取付位置を、該加速度センサと筐体内側面との間の最小隙間が、該水槽の外側面と筐体内側面との間の最小隙間より大きく設定した位置とする。   According to the washing machine of the present embodiment, a bottomed cylindrical rotating tub that rotates around the vertical axis and enables dehydration operation in the casing, and a bottomed cylindrical water tub provided so as to contain the rotating tub Have The water tank is elastically supported via an anti-vibration support device, and includes an acceleration sensor for vibration detection on the upper outer surface of the water tank. When the acceleration sensor detects a predetermined vibration via the water tank based on the unbalanced state accompanying the rotation of the rotating tank, the dehydration operation control is changed and executed based on the detection signal. Is set at a position where the minimum gap between the acceleration sensor and the inner side surface of the casing is set larger than the minimum gap between the outer side surface of the water tank and the inner side surface of the casing.

(第1の実施形態)
以下、図1および図2に示す第1の実施形態につき説明する。
まず、図1は洗濯機全体の概略構成を示す縦断側面図、図2は洗濯機上部のトップカバーを外して示す平面図で、この実施形態に示す洗濯機は、例えば洗い運転から脱水運転までを自動的に行なうもので、外郭を形成する中空箱状の筐体1内には詳細は後述する回転槽4および水槽5を備えている。筐体1は、図1に示す如く箱状の外箱2と、この外箱2の上面を覆うように被着されたトップカバー3とから構成されている。
(First embodiment)
Hereinafter, the first embodiment shown in FIGS. 1 and 2 will be described.
First, FIG. 1 is a longitudinal side view showing a schematic configuration of the entire washing machine, and FIG. 2 is a plan view showing the top of the washing machine with a top cover removed. In the hollow box-shaped casing 1 forming the outer shell, a rotating tank 4 and a water tank 5 described later in detail are provided. As shown in FIG. 1, the housing 1 includes a box-shaped outer box 2 and a top cover 3 that is attached so as to cover the upper surface of the outer box 2.

前記トップカバー3は、中央部に洗濯物出入口6を形成していて、該洗濯物出入口6を開閉する例えば二つ折りの洗濯蓋7を回動可能に取付けている。このトップカバー3の前方外面には操作パネル8が設けられ、その内部には制御装置9を備えている。制御装置9は、図示しないCPU、ROM、RAMなどで構成されたマイクロコンピュータを主体としており、洗濯機の作動全般を制御する機能を担う。   The top cover 3 has a laundry entrance / exit 6 formed at the center thereof, and a double-folded laundry lid 7 for opening and closing the laundry entrance / exit 6 is rotatably attached thereto. An operation panel 8 is provided on the front outer surface of the top cover 3, and a control device 9 is provided therein. The control device 9 is mainly composed of a microcomputer composed of a CPU, ROM, RAM, etc. (not shown), and has a function of controlling the overall operation of the washing machine.

これに対し、トップカバー3の後方部は大きく***した空間をなす機構室3aを形成していて、その内部に後述する給水手段や安全レバー装置を備えている。給水手段は、図示しない水道の蛇口に接続される給水弁10、図示しないが柔軟仕上剤等を供給すべくセット可能な給水ケース11、および給水パイプ12を有する構成にあって、該給水パイプ12の先端部は前記水槽5内に連通接続されている。   On the other hand, the rear part of the top cover 3 forms a mechanism chamber 3a that forms a greatly raised space, and is provided with water supply means and a safety lever device to be described later. The water supply means has a water supply valve 10 connected to a faucet (not shown), a water supply case 11 (not shown) that can be set to supply a soft finish, and a water supply pipe 12, and the water supply pipe 12 Is connected in communication with the water tank 5.

一方、筐体1を構成する外箱2内には、前記水槽5を吊り棒装置を介して弾性的に支持している。すなわち、外箱2は四角箱状をなし、その四隅部の上部から夫々吊り棒1を揺動可能に垂下するとともに、各吊り棒13の下端部に弾性部材としてコイルばね14を装着し、該コイルばね14を介して水槽5を吊持したもので、もって弾性支持する吊り棒装置を構成している。このように、吊り棒装置を介して水槽5を弾性的に支持することは、水槽5の振動を緩衝して外箱2側への振動伝達を抑制する所謂防振支持装置として機能する。   On the other hand, in the outer box 2 constituting the housing 1, the water tank 5 is elastically supported via a suspension bar device. That is, the outer box 2 has a square box shape, and the suspension rods 1 are swingably suspended from the upper portions of the four corners, and coil springs 14 are attached to the lower ends of the suspension rods 13 as elastic members, The water tank 5 is suspended through a coil spring 14 and constitutes a suspension bar device that is elastically supported. Thus, elastically supporting the water tank 5 via the suspension bar device functions as a so-called anti-vibration support device that buffers the vibration of the water tank 5 and suppresses vibration transmission to the outer box 2 side.

ここで、上記水槽5の具体構成につき述べると、該水槽5は上面を開放した有底円筒状をなし、この底部の外面側には、図示しないモータを主体とする駆動装置15を取付けるとともに、水槽5から排水するための排水弁16および排水ホース17を配設している。
また、水槽5の上面を覆うように円盤状をなす水槽カバー18を嵌合するように被着している。
Here, the specific configuration of the water tank 5 will be described. The water tank 5 has a bottomed cylindrical shape with an open upper surface, and a driving device 15 mainly composed of a motor (not shown) is attached to the outer surface side of the bottom portion. A drain valve 16 and a drain hose 17 for draining from the water tank 5 are provided.
Further, a water tank cover 18 having a disk shape is attached so as to cover the upper surface of the water tank 5.

この水槽カバー18は、後部に内外を連通した給水パイプ接続口19を上方に突設していて、該接続口19には前記給水パイプ12が接続されている。この給水パイプ接続口19の裏面側には、これと対向する位置に給水ガイド部材20が一体的に設けられ、例えば給水をシャワー状に槽内方側に指向して供給可能としている。また、水槽カバー18の中央側には、洗濯物出し入れ用の開口18aを有し、この開口18aを開閉する内蓋21を回動可能に設けている。従って、内蓋21が開口18aを閉鎖状態にあるとき、水槽5は実質的に閉鎖された空間を形成する。   This water tank cover 18 has a water supply pipe connection port 19 that communicates with the inside and the outside at the rear, and protrudes upward. The water supply pipe 12 is connected to the connection port 19. A water supply guide member 20 is integrally provided on the back surface side of the water supply pipe connection port 19 at a position facing the water supply pipe connection port 19 so that, for example, water can be supplied in a shower-like manner toward the inside of the tank. In addition, an opening 18a for putting in and out the laundry is provided on the center side of the water tank cover 18, and an inner lid 21 for opening and closing the opening 18a is rotatably provided. Therefore, when the inner lid 21 is in the state of closing the opening 18a, the water tank 5 forms a substantially closed space.

次いで、前記回転槽4の具体構成につき述べると、回転槽4は前記水槽5の内部に回転可能に設けられており、水槽5と同様に有底円筒状をなし周壁に多数の透孔4aや凸部4bを設けており、上端開口部には液体バランサ22を取付固定している。回転槽4の底部中央には、前記駆動装置15から延出され水槽5底部を貫通して突出した中空筒状の脱水軸23が連結されている。この脱水軸23の中空部分には洗濯軸24が挿通され、その上端部を回転槽4の内底部に配置した撹拌体25と連結固定している。   Next, the specific configuration of the rotating tub 4 will be described. The rotating tub 4 is rotatably provided inside the water tank 5 and has a bottomed cylindrical shape like the water tank 5 and has a large number of through holes 4a and a peripheral wall. A convex portion 4b is provided, and a liquid balancer 22 is fixedly attached to the upper end opening. A hollow cylindrical dewatering shaft 23 extending from the driving device 15 and projecting through the bottom of the water tank 5 is connected to the center of the bottom of the rotary tank 4. A washing shaft 24 is inserted into the hollow portion of the dewatering shaft 23, and an upper end portion thereof is connected and fixed to a stirring body 25 disposed on the inner bottom portion of the rotating tub 4.

ところで、駆動装置15には、洗い運転と脱水運転における回転伝達を切り換えるクラッチ機構を具備しており(図示せず)、制御装置9は洗い運転時に洗濯軸24を駆動して撹拌体25を正逆回転させ、脱水運転時には脱水軸23の回転駆動を有効化して回転槽4を一方向に高速回転可能に制御する。   Incidentally, the drive device 15 is provided with a clutch mechanism (not shown) for switching the rotation transmission between the washing operation and the dewatering operation, and the control device 9 drives the washing shaft 24 during the washing operation so By rotating in the reverse direction, during the dehydrating operation, the rotational drive of the dewatering shaft 23 is validated to control the rotating tub 4 so that it can rotate in one direction at a high speed.

そして、前記トップカバー3の機構室3aに設けた安全レバー装置26は、詳細な説明は省略するが外箱2内に垂下する安全レバー27を具備している。この安全レバー27は、水槽5の外側面と上下方向にラップする位置まで垂下され、且つ図2に示すように径方向に所定の間隙Cを介して対峙するとともに揺動可能に設けられている。従って、水槽5が振動により所定の間隙Cよりも外方への揺れが大きくなったとき、水槽5の外側面が安全レバー27に当接するように、該安全レバー27の所定位置が定められている。なお、当接した場合には、安全レバー27の動作変位を受けて安全レバー装置26が具備するスイッチ機能(図示しない)が応答し、つまり振動検知手段として機能するもので、この検知結果は前記制御装置9に入力されるようにしている。   The safety lever device 26 provided in the mechanism chamber 3a of the top cover 3 includes a safety lever 27 that hangs down in the outer box 2 although a detailed description is omitted. The safety lever 27 hangs down to a position where it wraps in the vertical direction with the outer surface of the water tank 5, and is provided so as to be able to face and oscillate through a predetermined gap C in the radial direction as shown in FIG. . Therefore, the predetermined position of the safety lever 27 is determined so that the outer surface of the water tank 5 comes into contact with the safety lever 27 when the water tank 5 is vibrated outwardly beyond the predetermined gap C due to vibration. Yes. In the case of contact, the switch function (not shown) provided in the safety lever device 26 responds in response to the operation displacement of the safety lever 27, that is, functions as vibration detection means. It is input to the control device 9.

このように、安全レバー27の機械的な変位に基づく振動検知手段に対し、電気的な振動検知手段としての加速度センサ28を水槽5に取付固定している。この加速度センサ28は、例えば上下左右の2軸加速度センサにあって、その取付位置は、水槽5の振動振幅が顕著に表れる水槽5上部の外側面に取り付けられる。ただし、図2に示すように水槽5と筐体1(この場合、外箱2)との隙間は、コンパクト化のためにできるだけ小さく抑えた構成となしており、例えば本実施形態では筐体1の側方において最小隙間Aを形成しており、およそ26mm程度と狭小である。   In this way, the acceleration sensor 28 as an electrical vibration detecting means is attached and fixed to the water tank 5 with respect to the vibration detecting means based on the mechanical displacement of the safety lever 27. The acceleration sensor 28 is, for example, an up / down / left / right biaxial acceleration sensor, and the mounting position thereof is mounted on the outer surface of the upper portion of the water tank 5 where the vibration amplitude of the water tank 5 appears remarkably. However, as shown in FIG. 2, the gap between the water tank 5 and the housing 1 (in this case, the outer box 2) is configured to be as small as possible for compactness. For example, in the present embodiment, the housing 1 A minimum gap A is formed on the side of the plate and is as narrow as about 26 mm.

そこで本実施形態では、水槽5の外側面から外方に突出した加速度センサ28の端部と外箱2(この場合、蓋体30)内側面との間における最小隙間Bが、上記した水槽5の外側面と外箱2内側面との間の最小隙間Aより大きく設定した位置に取り付け(A<B)、もって外箱2側への衝突を避ける構成としている。なお、上記した安全レバー27における所定の間隙Cは、上記最小隙間Aよりも小さく設定している(C<A<B)。   Therefore, in the present embodiment, the minimum gap B between the end of the acceleration sensor 28 protruding outward from the outer surface of the water tank 5 and the inner surface of the outer box 2 (in this case, the lid 30) is the water tank 5 described above. Is attached to a position set larger than the minimum gap A between the outer side surface of the outer box 2 and the inner side surface of the outer box 2 (A <B), thereby avoiding a collision to the outer box 2 side. The predetermined gap C in the safety lever 27 is set smaller than the minimum gap A (C <A <B).

更に、加速度センサ28は洗濯機筐体1の後方に配置され、具体的には、四角箱状の外箱2の一側面たる背面側に近接配置されている。この外箱2の背面側には、保守点検などに有用な開口部29が形成されており、該開口部29はネジ止め手段など適宜の取付手段にて着脱可能とする蓋体30にて閉鎖状態に維持され、もって箱状の外箱2を構成している。   Furthermore, the acceleration sensor 28 is disposed behind the washing machine casing 1, and specifically, is disposed close to the back side, which is one side surface of the square box-shaped outer box 2. An opening 29 useful for maintenance and inspection is formed on the back side of the outer box 2, and the opening 29 is closed by a lid 30 that can be attached and detached by appropriate attachment means such as screwing means. Thus, the box-like outer box 2 is formed.

そして、加速度センサ28は、上記開口部29から水槽5に取り付けられた該加速度センサ28を直視できる位置に配設されている。すなわち、開口部29は例えば矩形状に開口形成されており、加速度センサ28は、その上下左右方向の開口領域内に位置しており、図2では左右方向の開口領域Xの内方に配設され、図1では上下方向の開口領域Yの内方に配設されていることを示している。このことは、加速度センサ28を水槽5への取り付けには通常ネジ止め手段(図示しない)を用いているが、そのドライバーなどの工具を開口部29から容易に差し込むことができるなど作業を簡単化している。なお、開口部29からは他に前記排水弁16、排水ホース17などの配管部分、或は図示しないリード線処理などを含む保守点検作業を可能としている。   And the acceleration sensor 28 is arrange | positioned in the position which can see this acceleration sensor 28 attached to the water tank 5 from the said opening part 29 directly. That is, the opening 29 is formed in, for example, a rectangular shape, and the acceleration sensor 28 is located in the opening area in the vertical and horizontal directions, and is disposed in the opening area X in the horizontal direction in FIG. In FIG. 1, it is shown that it is disposed inside the opening region Y in the vertical direction. This means that the screw sensor (not shown) is usually used to attach the acceleration sensor 28 to the water tank 5, but the tool such as a screwdriver can be easily inserted from the opening 29 to simplify the work. ing. In addition, maintenance inspection work including piping parts such as the drainage valve 16 and drainage hose 17 or lead wire processing (not shown) can be performed from the opening 29.

次に、上記構成の洗濯機の作用について説明する。
通常この種脱水兼用洗濯機では、操作パネル8の操作により所望の運転モード等が設定され、その操作信号を受けて前記制御装置9が予め記憶された制御プログラム等に基づき、洗い、すすぎ、脱水の各運転を自動的に実行する。以下、そのうちの脱水運転時における作用につき詳細に述べる。
Next, the operation of the washing machine configured as described above will be described.
Usually, in this kind of combined dehydrating washing machine, a desired operation mode is set by operating the operation panel 8, and the control device 9 receives the operation signal and performs washing, rinsing and dehydration based on a control program stored in advance. Each operation is automatically executed. Hereinafter, the action during the dehydration operation will be described in detail.

脱水運転では、駆動装置15への通電により脱水軸23が回転駆動され、すすぎ洗いを終えた洗濯物(図示しない)を収容した回転槽4を一方向に高速回転することで遠心脱水が行なわれる。この場合、回転槽4に大きなアンバランス量が生じることがなければ、回転槽4は正常な回転速度まで達して、洗濯物から抽出された水は透孔4aを経て水槽5側に放出され、排水弁16および排水ホース17を経て機外に排出される。制御装置9は、この脱水運転が所定時間行なわれたところで終了する。   In the dehydration operation, the dehydrating shaft 23 is rotationally driven by energization of the driving device 15, and centrifugal dehydration is performed by rotating the rotating tub 4 containing the laundry (not shown) after rinsing at high speed in one direction. . In this case, if a large unbalance amount does not occur in the rotating tub 4, the rotating tub 4 reaches a normal rotation speed, and water extracted from the laundry is discharged to the water tub 5 side through the through holes 4a. It is discharged out of the machine through the drain valve 16 and the drain hose 17. The control device 9 ends when this dehydration operation is performed for a predetermined time.

ところが、この脱水運転に入る前のすすぎ洗いでは撹拌体25の回転駆動により撹拌された洗濯物は、排水動作に伴い回転槽4内の下方部に集まった状態にある。このとき、洗濯物が回転槽4の内周囲のいずれかに偏った所謂アンバランスの配置状態となることがある。従って、このアンバランス状態のまま脱水運転を開始した場合、回転槽4はアンバランスな遠心作用を受けて槽上部ほど外方への揺れが大きくなり、これが所定以上のアンバランス量になれば正規の脱水回転が得られなくなる。   However, in the rinsing before the dehydration operation is started, the laundry agitated by the rotational drive of the agitator 25 is in a state of being gathered in the lower part in the rotating tub 4 along with the draining operation. At this time, the laundry may be in a so-called unbalanced arrangement state in which the laundry is biased to any one of the inner periphery of the rotating tub 4. Therefore, when the dehydration operation is started in this unbalanced state, the rotating tank 4 is subjected to an unbalanced centrifugal action, and the upper part of the tank is more swayed outward. No dehydration rotation can be obtained.

すなわち、特に脱水運転初期における共振点付近では振動振幅が大きくなることから、回転槽4は正常な回転速度に加速されない脱水不能の事態を招く。この場合、弾性支持された水槽5の振動振幅も大きく、例えば径方向の外方への揺れが所定距離Cを超えて大きくなった場合には、水槽5の外側面が安全レバー27に当接する。この当接による動作変位を受けて、安全レバー装置26が有するスイッチ機能が応答し、これを振動検知信号として入力した制御装置9は、例えば駆動装置15を一時的に停止するように制御する。   That is, the vibration amplitude becomes large especially near the resonance point in the initial stage of the dehydration operation, so that the rotation tank 4 is not accelerated to a normal rotation speed and thus cannot be dewatered. In this case, the vibration amplitude of the elastically supported water tank 5 is also large. For example, when the radial outward vibration increases beyond a predetermined distance C, the outer surface of the water tank 5 contacts the safety lever 27. . In response to the operation displacement due to the contact, the switch function of the safety lever device 26 responds, and the control device 9 that has input this as a vibration detection signal controls the drive device 15 to temporarily stop, for example.

このように、回転槽4の回転による脱水運転を一時停止した後、制御装置9は、駆動装置15を再起動する。ただし、この再起動の場合の回転槽4の回転速度は、間欠的に徐々に上昇するよう運転制御し、その遠心作用に応じて脱水も徐々に行なわれるようにする。この脱水運転制御の変更は、アンバランス状態を回避する上で有効な運転制御で、従って再起動後は水槽5と安全レバー27とは当接することがなく正常な脱水運転が実行される確率を高め得る。   As described above, after the dehydration operation by the rotation of the rotating tub 4 is temporarily stopped, the control device 9 restarts the driving device 15. However, the rotational speed of the rotating tub 4 in the case of this restart is controlled so as to gradually increase intermittently, and dehydration is gradually performed according to the centrifugal action. This change in the dehydration operation control is an operation control effective in avoiding an unbalanced state. Therefore, after restarting, the water tank 5 and the safety lever 27 do not come into contact with each other, and the probability that a normal dehydration operation is executed is obtained. Can increase.

なお、安全レバー27には水槽5の外側面が当接するとして開示したが、これに限らず、例えば該水槽5の上面を塞ぐ水槽カバー18の一部が安全レバー27と直接当接する構成とすることも、実質的に本実施形態と共通といえる。   In addition, although it disclosed that the outer surface of the water tank 5 contact | abuts on the safety lever 27, it is not restricted to this, For example, a part of the water tank cover 18 which block | closes the upper surface of this water tank 5 is set as the structure directly contact | abutted with the safety lever 27. This can be said to be substantially common to the present embodiment.

上記した水槽5の径方向の揺れには、安全レバー27による振動検知が有効に作動する。これに対し、水槽5の上下方向或は左右方向(周方向)の揺れが大きい場合には、径方向たる安全レバー27側への揺れは小さい場合がある。この場合、本実施形態の2軸加速度センサ28が有効に機能して振動検知し、検知した振動に応じた電気信号が制御装置9に入力される。制御装置9は、例えば上記した安全レバー27による振動検知したときと同様に脱水運転制御を変更して実行し、アンバランス状態を回避する上で有効な運転制御が行なわれる。   The vibration detection by the safety lever 27 is effectively activated for the above-described shaking of the water tank 5 in the radial direction. On the other hand, when the water tank 5 is greatly shaken in the vertical direction or the left-right direction (circumferential direction), the shake toward the safety lever 27 in the radial direction may be small. In this case, the biaxial acceleration sensor 28 of the present embodiment functions effectively to detect vibration, and an electric signal corresponding to the detected vibration is input to the control device 9. For example, the control device 9 changes and executes the dehydration operation control in the same manner as when the vibration is detected by the safety lever 27 described above, and the operation control effective in avoiding the unbalanced state is performed.

ただし、この加速度センサ28は重力加速度に対応する電気信号に変換できるので、検出結果のアンバランス量に応じた運転制御を行なうことが可能である。例えば、アンバランス量が大きいことが検知された場合、脱水運転を一時停止後、給水弁10などの給水手段を介して給水し、洗濯物を浸漬した状態で洗い運転と同様に撹拌体25による撹拌動作を行ない、洗濯物のアンバランス配置を是正する動作を行なう。そして、制御装置9は排水弁16を有する排水ホース17を介して排水した後、改めて脱水運転を開始する運転制御としてもよいなど、きめ細かな制御手段を採用できる利点を有する。   However, since this acceleration sensor 28 can be converted into an electric signal corresponding to the gravitational acceleration, it is possible to perform operation control according to the unbalance amount of the detection result. For example, when it is detected that the unbalance amount is large, after the dehydration operation is temporarily stopped, water is supplied through a water supply means such as the water supply valve 10 and the laundry is immersed in the washing body 25 in the same manner as in the washing operation. The agitation operation is performed to correct the unbalanced arrangement of the laundry. And the control apparatus 9 has the advantage that a fine control means can be employ | adopted, such as it being good also as operation control which starts a dehydration operation again after draining through the drainage hose 17 which has the drain valve 16. FIG.

また、本実施形態では図2に示すように、水槽5の外側面と外箱2内側面との間をコンパクト化のため実用に支障がない最小隙間A(例えば、26mm)としているのに対し、水槽5に取り付けた加速度センサ28と前記外箱2内側面(蓋体30に相当)との間における最小隙間Bを大きく設定するとともに、更には水槽5と安全レバー27との間の所定の間隙Cは、上記最小隙間Aよりも小さく設定しており、不等式で示す「C<A<B」が成り立つ配置構成としている。   Further, in the present embodiment, as shown in FIG. 2, the space between the outer surface of the water tank 5 and the inner surface of the outer box 2 is set to a minimum gap A (for example, 26 mm) that does not hinder practical use for compactness. The minimum gap B between the acceleration sensor 28 attached to the water tank 5 and the inner surface of the outer box 2 (corresponding to the lid 30) is set large, and further, a predetermined gap between the water tank 5 and the safety lever 27 is set. The gap C is set to be smaller than the minimum gap A, and has an arrangement configuration in which “C <A <B” shown by the inequality is satisfied.

これにより、水槽5の外方への揺れに対して側方の外箱2に衝突する以前に安全レバー27と当接し適正な振動検知を可能とする。また、加速度センサ29が外箱2側に衝突するのを回避でき、該センサ29が損傷することを防止できる。また、水槽5と外箱2との間の最小隙間Aを問題なく維持できるので、洗濯機全体のコンパクト化にも有利である。   Thereby, before it collides with the side outer case 2 with respect to the outward shaking of the water tank 5, it abuts on the safety lever 27 and enables proper vibration detection. Further, it is possible to avoid the acceleration sensor 29 from colliding with the outer box 2 side, and it is possible to prevent the sensor 29 from being damaged. Further, since the minimum gap A between the water tank 5 and the outer box 2 can be maintained without any problem, it is advantageous for making the washing machine compact.

このような洗濯機のコンパクト化の市場ニーズは高く、それは洗濯機の設置面積を小さく抑え、或は輸送時の積載面積を小さく抑えるなど、コスト的にも有利などの利便性が期待できるからである。ただし、その一方では洗濯物の収容空間(回転槽4)の大容量化が求められていることもあって、該回転槽4を内包する水槽5と筐体1との隙間は、一層狭くなる傾向にある。このため、加速度センサ29や安全レバー27等は振動検知手段として有用とするのみでなく的確な振動検知、および筐体1側との衝突回避は、上記コンパクト化を図る上で有効である。   There is a great market need for such a compact washing machine, because it can be expected to be advantageous in terms of cost, such as reducing the installation area of the washing machine or reducing the loading area during transportation. is there. However, on the other hand, since the capacity of the laundry storage space (rotating tub 4) is required to be increased, the gap between the water tub 5 containing the rotating tub 4 and the housing 1 is further narrowed. There is a tendency. For this reason, the acceleration sensor 29, the safety lever 27, and the like are not only useful as vibration detection means, but also accurate vibration detection and collision avoidance with the housing 1 are effective in achieving the above-described compactness.

一方、本実施形態では外箱2の背面側に開口部29を形成し、その開口領域X,Yで示す(図1,2参照)範囲内に位置するよう前記加速度センサ28を水槽5に取付固定している。この配置は、筐体1の背面たる開口部29から該加速度センサ28を直視できることにある。従って、加速度センサ28の保守点検等においてドライバーなどの工具類を容易に差し入れることができ、つまり加速センサ28の着脱作業を容易に行なうことができて便利である。   On the other hand, in the present embodiment, an opening 29 is formed on the back side of the outer case 2, and the acceleration sensor 28 is attached to the water tank 5 so as to be located within the range indicated by the opening regions X and Y (see FIGS. 1 and 2). It is fixed. This arrangement is that the acceleration sensor 28 can be directly viewed from the opening 29 on the back surface of the housing 1. Therefore, tools such as a screwdriver can be easily inserted in maintenance inspection of the acceleration sensor 28, that is, the acceleration sensor 28 can be easily attached and detached.

なお、この開口部29からは、他に排水弁16などの排水手段や、図示しないリード線処理なども扱うことができ、所謂点検用開口部として有用であるとともに、洗濯機の背面側にあって蓋体30で閉鎖されているので、正面からの商品(洗濯機)としての意匠効果を損なうこともない。ただし、該開口部29は外箱2の背面側に限らず、例えば加速度センサ28をはじめ、他の保守点検部材の配置に応じて、外箱2の側面側に形成することも可能である。   In addition, from this opening 29, other drainage means such as the drainage valve 16 and lead wire processing (not shown) can be handled, which is useful as a so-called inspection opening and on the back side of the washing machine. Therefore, the design effect as a product (washing machine) from the front is not impaired. However, the opening 29 is not limited to the rear surface side of the outer box 2, and can be formed on the side surface side of the outer box 2 according to the arrangement of other maintenance inspection members including the acceleration sensor 28, for example.

なお、図3〜図6は第2〜第3の実施形態を示すもので、上記第1の実施形態と実質的に同一部分には同一符号を付して説明を省略し、異なる点につき詳細に説明する。   3 to 6 show the second to third embodiments. The substantially same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. Explained.

(第2の実施の形態)
そのうち図3,図4は、第2の実施形態を示すもので、図3は図1相当図で、図4は図2相当図である。このものは、加速度センサ28の保護および安全レバー27による振動検知に関連して突状部31を設けた点で異なり、配置構成など他は上記第1の実施形態で述べた構成と実質的に共通である。
(Second Embodiment)
3 and 4 show the second embodiment, FIG. 3 is a view corresponding to FIG. 1, and FIG. 4 is a view corresponding to FIG. This is different in that the protrusion 31 is provided in relation to protection of the acceleration sensor 28 and vibration detection by the safety lever 27, and the arrangement configuration and the like are substantially the same as the configuration described in the first embodiment. It is common.

すなわち、上記突状部31は水槽カバー18と一体に形成され、前記加速度センサ28の上方を覆うように庇状に外方に張り出し、図4に示す平面視で円弧形状に突出している。その突出端部は、加速度センサ28の外方への突出量を超えて延び、その一部は前記安全レバー27と所定の間隙Cをおいて対峙している。   That is, the protruding portion 31 is formed integrally with the water tank cover 18 and projects outward in a bowl shape so as to cover the upper side of the acceleration sensor 28, and protrudes in an arc shape in a plan view shown in FIG. The protruding end portion extends beyond the outward protruding amount of the acceleration sensor 28, and a part of the protruding end portion faces the safety lever 27 with a predetermined gap C therebetween.

なお、上記第1の実施形態に比して突状部31を外方に突出して設けたので、外箱2との衝突を回避すべく該外箱2を構成する蓋体32は、少なくとも突出した分だけ後方に膨出され、内面側に凹所を形成した構成としている。   In addition, since the protruding portion 31 is provided so as to protrude outward as compared with the first embodiment, the lid 32 constituting the outer box 2 is at least protruding so as to avoid a collision with the outer box 2. As a result, it is bulged rearward and a recess is formed on the inner surface side.

斯くして、第2の実施形態によれば、加速度センサ28と近接した位置の水槽5上部の水槽カバー18に設けられ、該加速度センサ28の突出量より大きく外方に張り出した突状部31を備えた構成とした。これにより、加速度センサ28の突出端部が外箱2側に直接衝突することは回避でき、損傷するおそれもなく長期使用が可能となる。しかも、突状部31を安全レバー27と当接して振動検知する構成としたので、該突状部31と安全レバー27とを所定位置に対峙し確実に当接する位置関係を得ることが容易で、且つ水槽5の外側面を直接当接させていたときのように水槽5が損傷する憂いもなくなる点で有利である。   Thus, according to the second embodiment, the protruding portion 31 provided on the water tank cover 18 at the upper part of the water tank 5 at a position close to the acceleration sensor 28 and projecting outward larger than the protruding amount of the acceleration sensor 28. It was set as the structure provided with. Thereby, it is possible to avoid the protruding end portion of the acceleration sensor 28 from directly colliding with the outer case 2 side, and it is possible to use it for a long time without fear of being damaged. In addition, since the protrusion 31 is in contact with the safety lever 27 to detect vibration, it is easy to obtain a positional relationship in which the protrusion 31 and the safety lever 27 are in contact with each other at a predetermined position. In addition, it is advantageous in that there is no fear of the water tank 5 being damaged like when the outer surface of the water tank 5 is in direct contact.

なお、突状部31は水槽カバー18と一体に形成したが、別体でもよいことはもとより、これは水槽5の上部を構成する部材に相当することから、実質的に水槽5側から突出した構成であるといえ、また他の構成として、例えば加速度センサ28の水槽5への取付板を利用して、これに庇状に張り出した突状部を形成してよいなど、種々変形して実施可能である。   Although the protrusion 31 is formed integrally with the water tank cover 18, it may be a separate body, and since it corresponds to a member constituting the upper part of the water tank 5, it substantially protrudes from the water tank 5 side. It can be said that this is a configuration, and as another configuration, for example, using a mounting plate of the acceleration sensor 28 to the water tank 5, a protruding portion protruding in a bowl shape may be formed on the mounting plate. Is possible.

(第3の実施の形態)
図5,6は、第3の実施形態を示すもので、図5は図1相当図、図6は図2相当図である。このものは、乾燥機能付の洗濯機に展開した実施形態にあって、具体的には乾燥機能を構成する乾燥風ダクトを加速度センサ28の衝突保護に活用した点で上記第1の実施形態とは異なり、他はほぼ共通の構成とするものである。
(Third embodiment)
5 and 6 show a third embodiment, FIG. 5 is a diagram corresponding to FIG. 1, and FIG. 6 is a diagram corresponding to FIG. This is an embodiment developed in a washing machine with a drying function. Specifically, the drying air duct constituting the drying function is used for collision protection of the acceleration sensor 28, and the first embodiment is different from the first embodiment. The others are almost the same in configuration.

まず、本実施形態にいう乾燥機能につき、特に図5に概略構成を示しており、トップカバー3の機構室3a内に、前記給水弁10等の給水手段と隣接して温風供給装置33を備えている。該温風供給装置33は、詳細な説明は省略するが背面側の吸気路34から外気を吸引する送風機と、該送風機から吐出される送風を加熱するヒータとを具備してなり、前記送風機はヒータで加熱され温風化された乾燥風を、供給パイプ(図示しない)および該供給パイプを接続する供給パイプ接続口35(図6参照)を介して水槽5内に供給可能としている。   First, regarding the drying function referred to in the present embodiment, a schematic configuration is shown particularly in FIG. 5, and a hot air supply device 33 is provided in the mechanism chamber 3 a of the top cover 3 adjacent to the water supply means such as the water supply valve 10. I have. Although not described in detail, the hot air supply device 33 includes a blower that sucks outside air from the intake passage 34 on the back side, and a heater that heats the blown air discharged from the blower. Dry air heated by a heater and heated to warm air can be supplied into the water tank 5 via a supply pipe (not shown) and a supply pipe connection port 35 (see FIG. 6) connecting the supply pipe.

すなわち、供給パイプ接続口35は水槽カバー18に突出形成され、前記給水パイプ接続口19と並んで水槽5内(回転槽4内)を臨む位置に配設されている。従って、上記した乾燥風は、前記したように内蓋21で閉鎖され実質的に閉鎖された空間を形成する水槽5内に供給されることで、回転槽4内にも十分に供給可能となる。この場合、例えば回転槽4を低速回転させながら乾燥風を供給することで、収容された洗濯物の乾燥作用が効果的に行なわれる。   That is, the supply pipe connection port 35 is formed so as to protrude from the water tank cover 18 and is arranged at a position facing the inside of the water tank 5 (inside the rotary tank 4) along with the water supply pipe connection port 19. Therefore, the above-described dry air can be sufficiently supplied also into the rotating tub 4 by being supplied into the water tank 5 which is closed by the inner lid 21 and forms a substantially closed space as described above. . In this case, for example, by supplying the drying air while rotating the rotating tub 4 at a low speed, the stored laundry is effectively dried.

乾燥作用を終えた乾燥風は、水槽5下部の連通口36から水槽5の背面側に設けた排気ダクト37に流入して上昇する。この排気ダクト37の上端部は、水槽カバー18の上面にまで延び、やゝ前方に至り排気口(図示しない)に着脱可能に設けた排気フィルタ38を通して筐体1内の上方に排出する構成としている。その乾燥風は、例えば洗濯物出入口6を閉鎖した状態の洗濯蓋7の周囲の隙間や、必要に応じて洗濯蓋7などに設けた排気用の小孔を介して機外に排出される。なお、上記排気フィルタ38は洗濯蓋7を開放した状態で視認でき着脱操作を可能とする位置に設けてあり、保守点検を容易にしている。   The drying air that has finished the drying action flows into the exhaust duct 37 provided on the back side of the water tank 5 from the communication port 36 at the bottom of the water tank 5 and rises. The upper end portion of the exhaust duct 37 extends to the upper surface of the water tank cover 18 and is exhausted upward in the housing 1 through an exhaust filter 38 that reaches the front of the tub and is detachably provided at an exhaust port (not shown). Yes. The drying air is discharged out of the machine, for example, through a gap around the laundry lid 7 with the laundry entrance 6 closed, or through a small exhaust hole provided in the laundry lid 7 as necessary. The exhaust filter 38 is provided at a position where the exhaust filter 38 can be seen with the washing lid 7 open and can be attached and detached, thereby facilitating maintenance and inspection.

このように、温風供給装置33と、該温風供給装置33にて温風化した乾燥風を水槽5内に供給し、排気ダクト37を経て水槽5外に排出するようにしてなる所謂乾燥風ダクトとを具備した構成は、洗濯物を乾燥する機能(乾燥機能)を構成するものである。   In this way, the warm air supply device 33 and the so-called dry air in which the dry air warmed by the warm air supply device 33 is supplied into the water tank 5 and discharged to the outside of the water tank 5 through the exhaust duct 37. The structure provided with the duct constitutes a function of drying the laundry (drying function).

そして、乾燥風ダクトを構成する排気ダクト37は、特に図6からも明らかなように水槽5の外側面(図中破線で示す)から後方たる外方に突出した形態にある。この突出した部位(以下、突出部位37aという)が、水槽5の振動により外箱2の背面を形成する蓋体39と衝突しないように、蓋体39には外方に大きく膨出した構成としている。   And the exhaust duct 37 which comprises a dry-air duct exists in the form protruded to the outward which is back from the outer side surface (indicated with the broken line in the figure) of the water tank 5, as it is clear also from FIG. In order to prevent the protruding portion (hereinafter referred to as the protruding portion 37a) from colliding with the lid 39 that forms the back surface of the outer case 2 due to the vibration of the water tank 5, the lid 39 is configured to bulge outward. Yes.

ところで、安全レバー27や加速度センサ28などの配置は、水槽5と外箱2との間における最小隙間Aに対し上記第1の実施形態と同様の関係に設置されている。前記排気ダクト37は、その突出部位37aが加速度センサ28の近傍から外方に突出する構成としており、その突出量は加速度センサ28の突出量より大きくしている。このため、排気ダクト37は、水槽5が大きく揺れた場合でも加速度センサ28が筐体1の背面側を構成する外箱2側と直接衝突することがないように作用し、つまり加速度センサ28を保護する機能を有するもので、この点で第1の実施形態よりも一層確実といえる。   By the way, the arrangement of the safety lever 27, the acceleration sensor 28, and the like is installed in the same relationship as in the first embodiment with respect to the minimum gap A between the water tank 5 and the outer box 2. The exhaust duct 37 has a protruding portion 37 a protruding outward from the vicinity of the acceleration sensor 28, and the protruding amount is larger than the protruding amount of the acceleration sensor 28. For this reason, the exhaust duct 37 acts so that the acceleration sensor 28 does not directly collide with the outer case 2 constituting the back side of the housing 1 even when the water tank 5 is greatly shaken. It has a function to protect, and in this respect, it can be said to be more reliable than the first embodiment.

斯くして、第3の実施形態たる乾燥機能付の洗濯機によれば、水槽5の外側面から外方に突出する排気ダクト37を設けた。その突出部位37aの突出基部の近傍にあって、水槽5の外側面に加速度センサ28を取付固定している。この加速度センサ28の外方への突出量より、排気ダクト37の同突出量を大きくしてある。このため、排気ダクト37の水槽5外側面より外方に突出した突出部位37aが、所謂第2の実施形態で述べた突状部と同様に機能し、加速度センサ28が外箱2側に直接衝突するのを回避し、保護する形態を得るものである。   Thus, according to the washing machine with a drying function according to the third embodiment, the exhaust duct 37 protruding outward from the outer surface of the water tub 5 is provided. The acceleration sensor 28 is attached and fixed to the outer surface of the water tank 5 in the vicinity of the protruding base portion of the protruding portion 37a. The protrusion amount of the exhaust duct 37 is made larger than the protrusion amount of the acceleration sensor 28 to the outside. For this reason, the projecting portion 37a projecting outward from the outer surface of the water tank 5 of the exhaust duct 37 functions in the same manner as the projecting portion described in the so-called second embodiment, and the acceleration sensor 28 is directly directed to the outer box 2 side. A form that avoids collision and protects is obtained.

従って、乾燥機能付の洗濯機では、その乾燥風ダクトを水槽5の外側面から外方に突出した部位を、加速度センサ28を保護するなどの突状部として活用することで、格別新規な構成を必要とせず複雑化することなく、且つ加速度センサ28による長期にわたる水槽5の振動検知が的確に行なえるなど、上記各実施形態とほぼ同様の作用効果が期待できる洗濯機を提供できる。   Therefore, in a washing machine with a drying function, a portion of the drying air duct protruding outward from the outer surface of the water tank 5 is used as a protruding portion for protecting the acceleration sensor 28, thereby providing a particularly novel configuration. Therefore, the washing machine can be expected to have substantially the same operational effects as those of the above-described embodiments, such that the acceleration sensor 28 can accurately detect the vibration of the water tank 5 over a long period of time without being complicated.

なお、上記した乾燥機能では、常に外気を吸入し乾燥に寄与した後の乾燥風(排気)を機外に排出する所謂排気タイプの構成につき述べたが、これに限らず、乾燥風を循環するタイプの循環ダクトを有する構成にも適用でき、従って乾燥風ダクトとしては上記した排気ダクトに限定されない。   In the above-described drying function, a so-called exhaust type configuration is described in which dry air (exhaust air) that always inhales outside air and contributes to drying is discharged to the outside of the apparatus. The present invention can also be applied to a configuration having a circulation duct of a type, and therefore the dry air duct is not limited to the exhaust duct described above.

その他、上記した第1〜第3の実施形態に限らず、例えば各実施形態を適宜組み合わせて実施してもよいし、加速度センサ28は2軸に限らず、例えば3軸タイプとして振動方向を含む検知精度を高めることも可能であり、また安全レバー27も必要に応じて設ければよいなど、種々変形して実施可能である。   In addition to the first to third embodiments described above, for example, the embodiments may be appropriately combined, and the acceleration sensor 28 is not limited to two axes but includes, for example, a three-axis type including a vibration direction. The detection accuracy can be increased, and the safety lever 27 can be provided as necessary, and various modifications can be made.

以上、本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略,置き換え、変更を行なうことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。   As mentioned above, although several embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
