Description

本発明は、筐体内の水槽を傾斜させることが可能な洗濯機に関する。   The present invention relates to a washing machine capable of tilting a water tank in a housing.

従来から、洗濯脱水槽を内包する水槽を、筐体上部から吊り棒を介して吊り下げるようにした形式の全自動洗濯乾燥機（以下、単に洗濯機と称する）が存在する。このような形式の洗濯機は、一般的に、水槽を予め一定の角度で傾斜させた状態で筐体内に常時配置されるようになっている。この種の洗濯機は、水槽を傾斜させることで、洗濯物の出し入れを容易にし、また洗濯物の洗浄効率や乾燥効率の向上を図ることを目的としている。   2. Description of the Related Art Conventionally, there is a fully automatic washing / drying machine (hereinafter simply referred to as a washing machine) in which a water tank containing a laundry dewatering tank is suspended from an upper part of a housing via a suspension rod. In general, a washing machine of this type is always arranged in a housing in a state where a water tank is inclined at a predetermined angle in advance. The purpose of this type of washing machine is to make it easy to put in and take out the laundry by tilting the water tank, and to improve the washing efficiency and the drying efficiency of the laundry.

そのような例として、「ケースと、前記ケースの内部に、前方上側部が前記ケースの前面部側に一定角度に傾いて取り付けられ、洗濯水を貯蔵する水槽および前記水槽の内部に設けられ、洗濯物を洗濯する内槽からなる洗濯槽と、前記内槽を回転させる駆動手段とを含んでなる、傾斜式洗濯槽を有する洗濯機において、前記ケースの後面部に設けられた開口部と、外側に膨出部が形成され、前記開口部に被せられるバックカバーとを含んでなる傾斜式洗濯槽を有する洗濯機」が提案されている（例えば、特許文献１参照）。   As such an example, “the case and the inside of the case, the front upper side portion is attached to the front side of the case inclined at a certain angle, provided in the water tank for storing the washing water and the inside of the water tank, In a washing machine having an inclined washing tub, comprising: a washing tub comprising an inner tub for washing laundry; and a driving means for rotating the inner tub; an opening provided in a rear surface portion of the case; There has been proposed a “washing machine having an inclined washing tub having a bulging portion formed on the outside and including a back cover covering the opening (see, for example, Patent Document 1).

特開２００４−１６０２５９号公報（第４頁、第１図など）Japanese Unexamined Patent Application Publication No. 2004-160259 (page 4, FIG. 1, etc.)

水槽を傾斜させる場合に注意しなければならないことは、吊り棒および吊り棒の下側に設けられている防振部（サスペンションやダンパー等）と、水槽の外周面とを不必要に接触させないようにすることである。吊り棒や防振部が水槽の外周面に接触してしまうと、想定していない振動や騒音が発生してしまうからである。この振動や騒音は、ユーザに不快感を与えるだけでなく、洗濯機の故障の原因にもなりかねないからである。   Care must be taken when tilting the aquarium so that the suspension rod and the anti-vibration part (suspension, damper, etc.) provided on the underside of the suspension rod do not unnecessarily contact the outer perimeter of the aquarium. Is to do. This is because unexpected vibration and noise are generated when the hanging rod and the vibration isolating portion come into contact with the outer peripheral surface of the water tank. This is because the vibration and noise not only make the user uncomfortable, but may also cause the washing machine to malfunction.

上記の洗濯機は、筐体の前方突出部を取り除くことで、水槽が直立する洗濯機の筐体を共用することができるようにしたものである。しかしながら、このような構造では、通常の筐体内において水槽を傾斜させなければならず、吊り棒および防振部に水槽の外周面を接触させないようにするためには、狭い範囲の角度で水槽を傾斜させるように設計しなければならない。また、何らの対策も講じずに水槽を強制的に傾斜させるようにすると、吊り棒および防振部に水槽の外周面が接触してしまう可能性が高くなってしまう。   The washing machine described above is configured such that the casing of the washing machine in which the water tank stands upright can be shared by removing the front protruding portion of the casing. However, in such a structure, the water tank must be inclined in a normal housing, and in order to prevent the outer peripheral surface of the water tank from coming into contact with the suspension rod and the vibration isolator, the water tank should be set at a narrow angle. Must be designed to tilt. Further, if the water tank is forcibly inclined without taking any measures, there is a high possibility that the outer peripheral surface of the water tank comes into contact with the suspension rod and the vibration isolator.

本発明は、上記のような問題を解決するためになされたもので、水槽を支持している吊り棒等を水槽の外周面に不必要に接触させずに、水槽を傾斜させることができる洗濯機を提供するものである。   The present invention has been made to solve the above-described problems, and is a laundry that can tilt a water tank without unnecessarily contacting a suspension rod that supports the water tank with the outer peripheral surface of the water tank. The machine is provided.

本発明に係る洗濯機は、筐体と、洗濯脱水槽を内装した水槽と、前記筐体内に設けられ、前記水槽を吊り下げ支持する複数の吊り棒と、前記水槽から突出して設けられ、前記吊り棒を通す貫通穴が形成された複数の継ぎ手部と、前記吊り棒の下部に設けられ、前記貫通穴を通った前記吊り棒を前記継ぎ手部に連結させる防振部とを備え、前記水槽は、前記吊り棒を利用して傾斜可能とされており、前記貫通穴が前記水槽の傾斜方向に沿う長穴となっているものである。   The washing machine according to the present invention is provided with a housing, a water tub equipped with a washing and dewatering tub, a plurality of suspension bars provided in the housing and supporting the water tub, and protruding from the water tub, A plurality of joint portions formed with through holes through which the suspension rods pass; and a vibration isolating portion provided at a lower portion of the suspension rods and connecting the suspension rods through the through holes to the joint portions; Is capable of tilting using the suspension rod, and the through hole is a long hole along the tilt direction of the water tank.

本発明の洗濯機によれば、水槽の傾斜に応じて、水槽から突出して設けられた継ぎ手部に連結して水槽を吊り下げ支持している吊り棒が、継ぎ手部に形成された貫通穴の長穴に沿って移動することができるので、吊り棒等を水槽の外周面に不必要に接触させることなく、広い範囲に渡って水槽を傾斜させることができるようになる。   According to the washing machine of the present invention, depending on the inclination of the water tub, the suspension rod connected to the joint portion protruding from the water tub and supporting the water tub is supported by the through hole formed in the joint portion. Since it can move along the long hole, the water tank can be inclined over a wide range without unnecessarily bringing a suspension rod or the like into contact with the outer peripheral surface of the water tank.

以下、本発明の実施の形態を図面に基づいて説明する。図１は、本発明の実施の形態に係る洗濯機１００を側面から見た概略構成を示す縦断面図である。この洗濯機１００は、洗濯物の洗浄（洗い、すすぎを含む）工程、脱水工程、および乾燥工程等を自動で行なうことが可能なものである。なお、図１において、図の右側を洗濯機１００の前側（水槽２０の前側でもある）とし、図の左側を洗濯機１００の後側（水槽２０の後側でもある）として説明する。また、図１を含め、以下の各図面では各構成部材の大きさの関係が実際のものとは異なる場合がある。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a schematic configuration of a washing machine 100 according to an embodiment of the present invention as viewed from the side. The washing machine 100 can automatically perform washing (including washing and rinsing) steps, dehydration steps, and drying steps of laundry. In FIG. 1, the right side of the drawing will be described as the front side of the washing machine 100 (also the front side of the water tub 20), and the left side of the drawing will be described as the rear side of the washing machine 100 (also the back side of the water tub 20). In addition, in the following drawings including FIG. 1, the size relationship of each component may be different from the actual one.

この洗濯機１００においては、洗濯脱水槽（内槽）２６を内装した水槽（外槽）２０が、筐体３０内において、吊り棒４０により傾斜可能に吊り下げ支持されている。水槽２０は、各行程あるいは洗濯物の量に応じて直立または傾斜した状態で使用される。   In the washing machine 100, a water tank (outer tank) 20 having a washing / dehydrating tank (inner tank) 26 is suspended and supported by a suspension bar 40 in a tiltable manner in a housing 30. The water tank 20 is used in an upright or inclined state according to each stroke or the amount of laundry.

筐体３０は、上部筐体２８と下部筐体２９とで構成されている。水槽２０は、上部に流体バランサ２７が設けられた洗濯脱水槽２６を外包し、水槽２０の底部には、動力伝達機構２１が固着されている。この動力伝達機構２１は、水槽２０の底部に取り付けられたモータ２２とベルトで連結されている。動力伝達機構２１の内側を構成する攪拌翼軸２３には、攪拌翼（パルセータ）２４が連結され、動力伝達機構２１の外側を構成する外側軸２５には洗濯脱水槽２６が連結されている。なお、動力伝達機構２１はダイレクトドライブ方式としてもよい。   The housing 30 is composed of an upper housing 28 and a lower housing 29. The water tank 20 encloses a washing and dewatering tank 26 provided with a fluid balancer 27 at the top, and a power transmission mechanism 21 is fixed to the bottom of the water tank 20. The power transmission mechanism 21 is connected to a motor 22 attached to the bottom of the water tank 20 by a belt. A stirring blade (pulsator) 24 is connected to the stirring blade shaft 23 constituting the inside of the power transmission mechanism 21, and a washing / dehydrating tub 26 is connected to the outer shaft 25 constituting the outside of the power transmission mechanism 21. The power transmission mechanism 21 may be a direct drive system.

吊り棒４０は、筐体３０の前後側に少なくとも１つずつ、好ましくは前後２つずつ設けられている。前側の吊り棒４０は、その上部が前側吊り棒上部支持部１０および球面軸受４１により支持され、後側の吊り棒４０は、その上部が筐体３０の上部に取り付けられている後方可動ユニット部３１により支持されている。これらの吊り棒４０は、前後側でその本数を変化させてもよいし、吊り棒４０の長さを前後側で異なるようにしてもよい。   At least one suspension rod 40 is provided on the front and rear sides of the housing 30, preferably two front and rear. The upper part of the front suspension bar 40 is supported by the front suspension bar upper support part 10 and the spherical bearing 41, and the rear suspension bar 40 has a rear movable unit part whose upper part is attached to the upper part of the housing 30. 31 is supported. The number of these hanging rods 40 may be changed on the front and rear sides, and the length of the hanging rod 40 may be different on the front and rear sides.

後方可動ユニット部３１は、水槽２０の後側の吊り棒４０を上下方向に移動（引き上げ／引き下ろし）可能に支持するものである。この後方可動ユニット部３１が、吊り棒４０を上下方向に移動させることによって、水槽２０の前側下端部が後側方向に移動させられ、水槽２０を任意の角度に傾斜可能としている。つまり、後方可動ユニット部３１は、洗濯機１００に設けられているマイコンなどからなる制御手段（図示せず）からの指示に基づいて、吊り棒４０を移動させ、水槽２０を任意の角度に傾斜させるのである。   The rear movable unit 31 supports the suspension rod 40 on the rear side of the water tub 20 so as to be movable (pick up / down) in the vertical direction. The rear movable unit 31 moves the suspension rod 40 in the vertical direction, whereby the front lower end of the water tank 20 is moved in the rear direction, and the water tank 20 can be inclined at an arbitrary angle. That is, the rear movable unit 31 moves the suspension bar 40 based on an instruction from a control unit (not shown) including a microcomputer provided in the washing machine 100, and tilts the water tank 20 at an arbitrary angle. To make it happen.

水槽２０の下部の前後側には、吊り棒４０を水槽２０に連結させるための継ぎ手部５０が、水槽２０の外周面より突出させて設けられている。継ぎ手部５０には貫通穴が形成されており、この貫通穴に吊り棒４０を通し、吊り棒４０の下部に設けた防振部３４を継ぎ手部５０に係止させて、吊り棒４０と水槽２０とを連結して水槽２０を支持している。継ぎ手部５０の構造および機能については、後で詳細に説明する。防振部３４は、吊り棒４０が継ぎ手部５０から抜けてしまうのを防止するとともに、継ぎ手部５０を安定支持するための防振構造を備えている。   A joint portion 50 for connecting the suspension rod 40 to the water tank 20 is provided on the front and rear sides of the lower part of the water tank 20 so as to protrude from the outer peripheral surface of the water tank 20. A through hole is formed in the joint portion 50. The suspension rod 40 is passed through the through hole, and the vibration isolator 34 provided at the lower portion of the suspension rod 40 is engaged with the joint portion 50 so that the suspension rod 40 and the water tank 20 is connected to support the water tank 20. The structure and function of the joint portion 50 will be described in detail later. The vibration isolator 34 is provided with a vibration isolating structure for preventing the suspension rod 40 from coming off the joint portion 50 and stably supporting the joint portion 50.

図２は、水槽２０が前側に傾斜している状態の洗濯機１００を側面から見た概略構成を示す縦断面図である。水槽２０の傾斜は、行程に応じて予め自動的に定められているものであるが、ユーザからの指示に基づいて傾斜させることもできるようにしてもよい。   FIG. 2 is a longitudinal sectional view showing a schematic configuration of the washing machine 100 in a state where the water tank 20 is inclined to the front side as viewed from the side. Although the inclination of the water tank 20 is automatically determined in advance according to the stroke, it may be configured to be inclined based on an instruction from the user.

水槽２０を傾斜させると、洗濯物の出し入れが容易になり、また、洗濯物の洗浄効率および乾燥効率が向上するという効果が得られる。この効果を更に向上させるためには、運転に応じて、所望の傾斜角度に水槽２０を調整できるようにすることが望ましい。また、洗濯の目的に応じて、水槽２０の傾斜角度を調整可能にすることが望ましい。ただし、洗濯物の脱水行程では、振動抑制の観点から、水槽２０を直立状態にした方がよい。   When the water tank 20 is tilted, the laundry can be easily taken in and out, and the washing efficiency and the drying efficiency of the laundry can be improved. In order to further improve this effect, it is desirable that the water tank 20 can be adjusted to a desired inclination angle according to the operation. Further, it is desirable that the inclination angle of the water tank 20 can be adjusted according to the purpose of washing. However, in the laundry dehydration process, the water tank 20 should be in an upright state from the viewpoint of vibration suppression.

この例の場合、水槽２０の傾斜は、後側の吊り棒４０を上下方向に移動させることによって行なう。たとえば、水槽２０を洗濯機１００の前側に傾斜させたいときには、後部可動ユニット部３１を利用して吊り棒４０を上に引き上げる。後部可動ユニット部３１を制御する制御手段は、水槽２０を傾斜させる角度に応じて、吊り棒４０の引き上げ量および引き下げ量を調整するようになっている。   In the case of this example, the water tank 20 is inclined by moving the rear hanging rod 40 in the vertical direction. For example, when it is desired to incline the water tank 20 to the front side of the washing machine 100, the suspension rod 40 is pulled up using the rear movable unit 31. The control means for controlling the rear movable unit 31 adjusts the lifting amount and the lowering amount of the suspension bar 40 according to the angle at which the water tank 20 is inclined.

水槽２０を傾斜させる場合に注意しなければならないことは、吊り棒４０および防振部３４がそれらの可動範囲で、水槽２０の外周面や継ぎ手部５０と不必要に干渉してしまうことである。吊り棒４０および防振部３４が水槽２０の外周面や継ぎ手部５０と干渉すると、想定していない振動が吊り棒４０を介して筐体３０に伝播してしまうことになる。そうすると、ユーザに不快感を与えるだけでなく、洗濯機１００の故障の原因にもなりかねない。そのため、水槽２０の傾斜範囲では、吊り棒４０および防振部３４が、水槽２０の外周面や継ぎ手部５０と不必要に干渉しないようにしなければならない。   What should be noted when tilting the aquarium 20 is that the hanging rod 40 and the vibration isolator 34 interfere with the outer peripheral surface of the aquarium 20 and the joint portion 50 unnecessarily in their movable range. . If the suspension rod 40 and the vibration isolator 34 interfere with the outer peripheral surface of the water tank 20 and the joint portion 50, unexpected vibrations propagate to the housing 30 via the suspension rod 40. This not only makes the user uncomfortable, but may also cause the washing machine 100 to malfunction. Therefore, in the inclined range of the water tank 20, the suspension rod 40 and the vibration isolation part 34 must be prevented from unnecessarily interfering with the outer peripheral surface of the water tank 20 and the joint part 50.

水槽２０の傾斜角度が常時一定の場合には、その一定の傾斜角度に基づいて、吊り棒４０の長さ、継ぎ手部５０の大きさ、継ぎ手部５０に形成する貫通穴の大きさ等を設定すればよいが、水槽２０を任意の角度で傾斜させる場合にはそれでは不十分である。すなわち、継ぎ手部５０の貫通穴が、吊り棒４０の横断面形状よりもやや大きいだけの場合には、吊り棒４０の移動の自由度が制限されてしまい、狭い範囲の角度でしか水槽２０を傾斜させることができない。一方、貫通穴の径を極端に大きくすれば、吊り棒４０の前後方向の自由度を大きくすることは可能になるものの、水槽２０がぐらついて安定しない上に、継ぎ手部５０と防振部３４の間に摺動性向上のために設置された部材（球面座３８など）が貫通穴にひっかかり、摺動性を低下させてしまう可能性もある。   When the inclination angle of the water tank 20 is always constant, the length of the suspension rod 40, the size of the joint portion 50, the size of the through hole formed in the joint portion 50, etc. are set based on the constant inclination angle. However, this is not sufficient when the water tank 20 is inclined at an arbitrary angle. That is, when the through hole of the joint portion 50 is only slightly larger than the cross-sectional shape of the hanging rod 40, the degree of freedom of movement of the hanging rod 40 is limited, and the water tank 20 can be opened only in a narrow range of angles. It cannot be tilted. On the other hand, if the diameter of the through hole is made extremely large, the degree of freedom in the front-rear direction of the suspension rod 40 can be increased, but the water tank 20 is unstable and unstable, and the joint portion 50 and the vibration isolating portion 34. In the meantime, a member (such as the spherical seat 38) installed for improving the slidability may get caught in the through hole and reduce the slidability.

そこで、本発明では、吊り棒を支持している継ぎ手部５０に形成する貫通穴の形状を工夫することで、水槽２０の傾斜可能な角度を大きくしたまま、吊り棒４０および防振部３４と、水槽２０の外周面および継ぎ手部５０との不必要な干渉を防止できる種々の構成を提案する。   Therefore, in the present invention, by devising the shape of the through hole formed in the joint portion 50 that supports the suspension rod, the suspension rod 40 and the vibration isolation portion 34 Various configurations that can prevent unnecessary interference with the outer peripheral surface of the water tank 20 and the joint portion 50 are proposed.

図３は、継ぎ手部５０および防振部３４を拡大して示す縦断面図である。図示した継ぎ手部５０は、洗濯機１００の後側、すなわち水槽２０の後側下部に設けられているものである。この継ぎ手部５０の内部には吊り棒４０が貫通している。吊り棒４０の下部には、防振部３４が形成されており、防振部３４と継ぎ手部５０との間には、継ぎ手部５０と防振部３４の接触面の摺動性を良くするための球面座３８が設けられている。さらに、球面座３８と防振部３４の間には、水槽２０が回転する時の吊り棒４０の摺動に伴う球面座３８と防振部３４の摩擦による損傷等を防ぐための緩衝材３９が設置されている。   FIG. 3 is an enlarged longitudinal sectional view showing the joint portion 50 and the vibration isolation portion 34. The illustrated joint portion 50 is provided on the rear side of the washing machine 100, that is, on the lower rear side of the water tank 20. A suspension rod 40 passes through the joint portion 50. A vibration isolator 34 is formed in the lower part of the suspension rod 40, and between the vibration isolator 34 and the joint 50, the slidability of the contact surface between the joint 50 and the vibration isolator 34 is improved. A spherical seat 38 is provided. Further, a cushioning material 39 is provided between the spherical seat 38 and the vibration isolator 34 to prevent damage due to friction between the spherical seat 38 and the vibration isolator 34 due to the sliding of the suspension rod 40 when the water tank 20 rotates. Is installed.

防振部３４は、その中央部を吊り棒４０が貫通した状態で吊り棒４０に取り付けられ、継ぎ手部５０の下側に位置して、吊り棒４０が継ぎ手部５０の貫通穴５１から上方に抜けてしまうのを防止している。
防振部３４は、防振バネ３５と、防振バネ３５の両端に配置された上側バネ押さえ３６および下側バネ押さえ３７とで構成されている。これにより防振部３４は、継ぎ手部５０を介して、水槽２０を吊り棒４０に連結させて支持するとともに、継ぎ手部５０を介して伝播する水槽２０で発生した振動を吸収する役目も果たすようになっている。なお、防振部３４は、水槽２０で発生した振動を吸収できるものであればよく、たとえば、ダンパーやサスペンション、コイルバネ、防振用バネ、空気バネ等で構成することができる。 The vibration isolator 34 is attached to the suspension rod 40 with the suspension rod 40 penetrating through the center thereof, and is positioned below the joint portion 50 so that the suspension rod 40 extends upward from the through hole 51 of the joint portion 50. It prevents it from coming off.
The anti-vibration unit 34 includes an anti-vibration spring 35, and an upper spring retainer 36 and a lower spring retainer 37 disposed at both ends of the anti-vibration spring 35. As a result, the vibration isolator 34 supports the water tank 20 connected to the suspension rod 40 via the joint 50 and also serves to absorb vibration generated in the water tank 20 propagating via the joint 50. It has become. The vibration isolator 34 may be anything that can absorb the vibration generated in the water tank 20, and may be constituted by, for example, a damper, a suspension, a coil spring, a vibration isolating spring, an air spring, or the like.

図４は、水槽２０とその水槽２０の下部から突出する継ぎ手部５０の関係を示す説明図である。継ぎ手部５０には、吊り棒４０を通すための貫通穴５１と、貫通穴５１の内と外を連通して、吊り棒４０を貫通穴５１へ導入する吊り棒導入路５２が形成されている。
図４に示すように、貫通穴５１は、吊り棒４０の傾斜方向（この例では水槽２０の略前後側方向）に長い長穴であり、吊り棒導入路５２は貫通穴５１の穴方向と異なる向き（この例では水槽２０の径方向の外側向き）に開いている。なお、吊り棒の傾斜方向は水槽２０の略前後方向であるが、説明を簡略化するため、水槽の傾斜方向を単に水槽の前後側方向という場合もある。
上記長穴は、吊り棒４０を引き上げる方向すなわち径方向に（前側が八の字状、後側が逆八の字状に）傾いていると尚良い。
さらに上記長穴は、吊り棒４０の径に合わせて、水槽の前側と後側の継ぎ手部５０で、その幅を変えても良い。通常、水槽２０の後側の吊り棒４０が前側の吊り棒４０より太いので、それに合わせる。 FIG. 4 is an explanatory view showing the relationship between the water tank 20 and the joint portion 50 protruding from the lower part of the water tank 20. The joint portion 50 is formed with a through hole 51 through which the suspension rod 40 passes and a suspension rod introduction path 52 that communicates the inside and outside of the through hole 51 and introduces the suspension rod 40 into the through hole 51. .
As shown in FIG. 4, the through-hole 51 is a long hole that is long in the inclination direction of the suspension rod 40 (in this example, the substantially front-rear direction of the water tank 20). It opens in a different direction (in this example, outward in the radial direction of the water tank 20). In addition, although the inclination direction of a hanging rod is the substantially front-back direction of the water tank 20, in order to simplify description, the inclination direction of a water tank may only be called the front-back direction of a water tank.
It is more preferable that the long hole is inclined in the direction in which the suspension rod 40 is pulled up, that is, in the radial direction (the front side is an eight-letter shape and the rear side is an inverted eight-letter shape).
Further, the width of the elongated hole may be changed at the joint portion 50 on the front side and the rear side of the water tank in accordance with the diameter of the hanging rod 40. Usually, the suspension rod 40 on the rear side of the water tank 20 is thicker than the suspension rod 40 on the front side.

このように、貫通穴５１の形状を水槽２０の前後側方向に沿う長穴とすることにより、水槽２０の傾斜可能範囲（角度）を大きくしたまま、吊り棒４０および防振部３４を、水槽２０の外周面や継ぎ手部５０と不必要に干渉させないようにする事が可能となる。
また、吊り棒導入路５２を貫通穴５１の穴方向と異なる向きに開けていることで、吊り棒４０が貫通穴５１から抜けにくくなっている。
また、吊り棒導入路５２を水槽２０の径方向外側に向けて開けることにより、吊り棒４０を貫通穴５１に導入するのが容易となる。
さらに、吊り棒導入路５２の開口端や、吊り棒導入路５２と貫通穴５１との接続部を、面取り形状や曲面形状とすると、吊り棒４０の導入を容易でき、また緩衝材３９を貫通穴５１の角に引っ掛けることも防止できる。 Thus, by making the shape of the through hole 51 a long hole along the front-rear direction of the water tank 20, the suspension rod 40 and the vibration isolator 34 can be connected to the water tank while the tiltable range (angle) of the water tank 20 is increased. It is possible to prevent unnecessary interference with the outer peripheral surface 20 and the joint portion 50.
In addition, the suspension rod introduction path 52 is opened in a direction different from the hole direction of the through hole 51, so that the suspension rod 40 is difficult to be removed from the through hole 51.
Moreover, it becomes easy to introduce the suspension rod 40 into the through hole 51 by opening the suspension rod introduction path 52 toward the radially outer side of the water tank 20.
Furthermore, if the opening end of the suspension rod introduction path 52 and the connecting portion between the suspension rod introduction path 52 and the through hole 51 are chamfered or curved, the suspension rod 40 can be easily introduced and the buffer material 39 is penetrated. It is also possible to prevent hooking on the corner of the hole 51.

図５は、水槽２０の傾斜の状態とそれに対応する吊り棒の状態を示す説明図である。図５（ａ）は水槽２０が直立の状態（傾斜角０度の状態）を示し、図５（ｂ）は水槽２０が２０度傾斜した状態を示している。また、図５（ｃ）は、水槽２０の傾斜前後における水槽側面と吊り棒４０との位置関係を示している。
本実施の形態では、水槽２０の後側の吊り棒４０を引き上げることで、水槽２０を傾斜させるようにしているため、水槽２０が傾斜するとき、前側の吊り棒４０は水槽２０の前後方向に大きく移動するのに対して、後側の吊り棒４０は水槽２０の前後方向にそれ程大きく移動しない。従って、図４に示すように、後側の継ぎ手部５０の貫通穴５１の長さＬ１を、前側の継ぎ手部５０の貫通穴５１の長さＬ２よりも小さくすることができる。すなわち、Ｌ１＜Ｌ２の関係である。このようにすることで、洗濯脱水槽２６の摺動による吊り棒４０のぶれを抑えることができる。 FIG. 5 is an explanatory diagram showing the inclined state of the water tank 20 and the state of the suspension bar corresponding thereto. 5A shows a state where the water tank 20 is upright (state where the inclination angle is 0 degree), and FIG. 5B shows a state where the water tank 20 is inclined 20 degrees. FIG. 5C shows the positional relationship between the water tank side surface and the suspension rod 40 before and after the water tank 20 is inclined.
In the present embodiment, since the water tank 20 is inclined by pulling up the suspension rod 40 on the rear side of the water tank 20, when the water tank 20 is inclined, the front suspension rod 40 is arranged in the front-rear direction of the water tank 20. The rear hanging rod 40 does not move so much in the front-rear direction of the water tank 20 while moving greatly. Therefore, as shown in FIG. 4, the length L1 of the through hole 51 of the rear joint portion 50 can be made smaller than the length L2 of the through hole 51 of the front joint portion 50. That is, L1 <L2. By doing in this way, shaking of the hanging rod 40 by sliding of the washing / dehydrating tank 26 can be suppressed.

図５（ｃ）に示すように、水槽２０の後側における水槽側面に平行な面（細い波線で表示）と後側の吊り棒４０とがなす角度を、水槽２０の傾斜角０°の時はα１とし、水槽２０の傾斜角２０°の時はβ１とする。同様に、水槽２０の前側における水槽側面に平行な面（細い波線で表示）と前側の吊り棒４０とがなす角度を、水槽２０の傾斜角０°の時はα２とし、水槽２０の傾斜角２０°の時はβ２とする。以上の設定によれば、水槽２０の傾斜角０°の時、α１＝α２の関係が成り立つ。
また、水槽２０の傾斜角２０°の時の水槽２０の前側における水槽側面に平行な面と吊り棒４０のなす角度は、水槽２０の傾斜角０°の時より小さくなるのに対して、水槽２０の後側における水槽側面に平行な面と吊り棒４０のなす角度は、水槽２０の傾斜角０°の時より大きくなる。 As shown in FIG. 5 (c), when the angle between the plane parallel to the side of the aquarium on the rear side of the aquarium 20 (indicated by a thin wavy line) and the rear hanging rod 40 is 0 ° Is α1, and β1 when the water tank 20 has an inclination angle of 20 °. Similarly, the angle formed between the front surface of the water tank 20 parallel to the water tank side surface (indicated by a thin wavy line) and the front hanging rod 40 is α2 when the water tank 20 has an inclination angle of 0 °, and the inclination angle of the water tank 20 When the angle is 20 °, β2. According to the above setting, when the inclination angle of the water tank 20 is 0 °, the relationship α1 = α2 is established.
Further, the angle formed between the surface parallel to the side surface of the water tank 20 and the suspension bar 40 when the water tank 20 has an inclination angle of 20 ° is smaller than that when the water tank 20 has an inclination angle of 0 °, whereas the water tank 20 The angle formed by the surface parallel to the side surface of the water tank on the rear side of the tank 20 and the suspension rod 40 is larger than when the inclination angle of the water tank 20 is 0 °.

図６、図７は後側の継ぎ手部５０の形状を示したものである。継ぎ手部５０に形成される貫通穴５１の基本的な形状は、図６（ａ）に示すような平面形状および図６（ｂ）に示すような断面形状である。しかしながら、上記図５（ｃ）に示したように、水槽２０の側面に対しては後側の吊り棒２０がより大きく傾斜することを考慮して貫通穴５１の形状を決定するのが好ましい。そのような形状の一例を、図７（ａ）の平面図および図７（ｂ）の断面図に示す。図７の場合、水槽２０の後側の継ぎ手部５０における貫通穴５１の前側縁部が、その上方から下方に向かうに従って前側方向に延長されている。すなわち、上方の長穴の長さをＬ３、下方の長穴の長さをＬ４とするとき、Ｌ３＜Ｌ４となっている。このようにすることにより、吊り棒４０の水槽２０側面に対する傾斜の自由度が高まり、吊り棒４０及び防振部３４と、水槽２０の外周面や継ぎ手部５０との不必要な接触を防止できるとともに、水槽２０の摺動による吊り棒４０のぶれも抑えることができる。
なお、水槽２０の前側の継ぎ手部５０もこれに準じた態様とすることにより、ほぼ同様の効果が得られる。 6 and 7 show the shape of the joint portion 50 on the rear side. The basic shape of the through hole 51 formed in the joint portion 50 is a planar shape as shown in FIG. 6A and a cross-sectional shape as shown in FIG. However, as shown in FIG. 5C, it is preferable to determine the shape of the through hole 51 in consideration of the fact that the rear suspension rod 20 is more inclined with respect to the side surface of the water tank 20. An example of such a shape is shown in the plan view of FIG. 7A and the cross-sectional view of FIG. In the case of FIG. 7, the front edge of the through hole 51 in the joint 50 on the rear side of the water tub 20 is extended in the front direction from the upper side toward the lower side. That is, when the length of the upper slot is L3 and the length of the lower slot is L4, L3 <L4. By doing in this way, the freedom degree of the inclination with respect to the water tank 20 side surface of the hanging rod 40 increases, and the unnecessary contact with the hanging rod 40 and the vibration isolator 34, the outer peripheral surface of the water tank 20, and the joint part 50 can be prevented. At the same time, shaking of the suspension rod 40 due to sliding of the water tank 20 can be suppressed.
In addition, the substantially same effect is acquired by making the joint part 50 of the front side of the water tank 20 into the aspect according to this.

次に、継ぎ手部５０の貫通穴５１に吊り棒４０を導入するための吊り棒導入路５２について説明する。吊り棒４０は、通常、継ぎ手部５０の貫通穴５１の内と外を連通している吊り棒導入路５２を通して、貫通穴５１に導入される。既に図４において、吊り棒導入路５２が、貫通穴５１の長手方向と異なる向き、例えば、水槽２０の径方向の外側に向けて形成されているものを示した。ここでは、図８〜図１０に示した水槽２０の前側の継ぎ手部５０の形状図をもとに、別の吊り棒導入路５２を例示する。   Next, the suspension rod introduction path 52 for introducing the suspension rod 40 into the through hole 51 of the joint portion 50 will be described. The suspension rod 40 is usually introduced into the through hole 51 through a suspension rod introduction path 52 that communicates the inside and the outside of the through hole 51 of the joint portion 50. In FIG. 4, the suspension rod introduction path 52 has already been formed in a direction different from the longitudinal direction of the through hole 51, for example, outward in the radial direction of the water tank 20. Here, another suspension rod introduction path 52 is illustrated based on the shape of the joint 50 on the front side of the water tank 20 shown in FIGS.

図８は、吊り棒導入路５２が途中で折れ曲がった形状を有する例であり、図９、図１０は、吊り棒導入路５２に、貫通穴５１の外側から内側への押し込み圧力によって弾性変形する、吊り棒４０の径より狭い狭路部５３，５４が設けられている。これらによれば、運搬時、水槽２０の傾斜時、洗濯脱水槽の摺動時などの場合にも、吊り棒４０が吊り棒導入路５２から抜けることが防止され、洗濯機の信頼性が向上する。
なお、図８〜図１０に示した吊り棒導入路５２の形状は、水槽２０の後側の継ぎ手部５０にも適用できる。
また、吊り棒導入路５２の開口端部は、面取りまたは曲面に形成して、吊り棒４０の導入を容易にしておくのが好ましい。 FIG. 8 is an example in which the suspension rod introduction path 52 has a bent shape in the middle, and FIGS. 9 and 10 are elastically deformed into the suspension rod introduction path 52 by the pressing force from the outside to the inside of the through hole 51. Narrow path portions 53 and 54 that are narrower than the diameter of the suspension rod 40 are provided. According to these, the suspension bar 40 is prevented from coming out of the suspension bar introduction path 52 even during transportation, when the water tank 20 is inclined, or when the washing / dehydrating tank slides, and the reliability of the washing machine is improved. To do.
Note that the shape of the suspension rod introduction path 52 shown in FIGS. 8 to 10 can also be applied to the joint portion 50 on the rear side of the water tank 20.
Moreover, it is preferable that the opening end portion of the suspension rod introduction path 52 is chamfered or curved to facilitate introduction of the suspension rod 40.

図１１は水槽２０と水槽２０から突出する継ぎ手部５０の関係を示す説明図である。本実施の形態の洗濯機のように、水槽２０の後側の吊り棒４０を引き上げて、水槽２０を傾斜させる洗濯機にあっては、水槽２０の前側の吊り棒４０の方が、後側の吊り棒４０より前後方向に大きく移動する。このことを考慮すると、図１１に示すように、水槽２０の外周面から継ぎ手部５０の貫通穴５１の中心部までの距離は、水槽２０の後側の継ぎ手部５０の方を、水槽２０の前側の継ぎ手部５０より短くできる。すなわち、後側の当該部分の長さをＬ６、前側の当該部分の長さをＬ７とすると、Ｌ６＜Ｌ７とすることができる。これにより、水槽２０の後側において筐体３０と水槽２０との間にスペースが確保でき、筐体３０をコンパクトにしたり、筐体３０と水槽２０との間を有効活用することが可能となる。   FIG. 11 is an explanatory view showing the relationship between the water tank 20 and the joint portion 50 protruding from the water tank 20. As in the washing machine of the present embodiment, in the washing machine that pulls up the suspension bar 40 on the rear side of the water tank 20 and tilts the water tank 20, the suspension bar 40 on the front side of the water tank 20 is on the rear side. It moves largely in the front-rear direction than the hanging rod 40 of the. In consideration of this, as shown in FIG. 11, the distance from the outer peripheral surface of the water tank 20 to the center of the through hole 51 of the joint portion 50 is such that the joint portion 50 on the rear side of the water tank 20 is closer to the water tank 20. It can be shorter than the joint 50 on the front side. That is, when the length of the rear portion is L6 and the length of the front portion is L7, L6 <L7. Thereby, a space can be secured between the housing 30 and the water tank 20 on the rear side of the water tank 20, and the housing 30 can be made compact, or the space between the housing 30 and the water tank 20 can be effectively utilized. .

図１２は、継ぎ手部５０および貫通孔５１の位置と筐体３０の吊り棒上部支持部の位置との関係を示す説明図である。図１２に示すように、筐体３０の吊り棒支持部（水槽２０の後側では後方可動ユニット３１の有る部分、水槽２０の前側では前側吊り棒上部支持部１０の有る部分）を、吊り棒４０の下部を支持している継ぎ手部５０の対応する貫通穴５１の中心位置より、水槽２０の外周面に対して外側方向へずれた位置に設けるのが好ましい。なお、筐体３０のこれら吊り棒支持部は、継ぎ手部５０より、水槽２０の外周面に対して外側方向へずれた位置、例えば水槽２０の径方向の外側位置に設置してもよい。このようにすることで、水槽２０を吊るした状態で横力の影響を小さくすることができ、水槽２０を安定した状態で保つことができる。   FIG. 12 is an explanatory diagram showing the relationship between the positions of the joint portion 50 and the through hole 51 and the position of the suspension rod upper support portion of the housing 30. As shown in FIG. 12, the suspension rod support portion of the housing 30 (the portion with the rear movable unit 31 on the rear side of the water tank 20 and the portion with the front suspension rod upper support portion 10 on the front side of the water tank 20) It is preferable that the joint portion 50 supporting the lower portion of the joint 40 is provided at a position shifted outward from the outer peripheral surface of the water tank 20 from the center position of the corresponding through hole 51. In addition, you may install these suspension-bar support parts of the housing | casing 30 in the position shifted | deviated to the outer side with respect to the outer peripheral surface of the water tank 20 from the joint part 50, for example, the outer position of the radial direction of the water tank 20. By doing in this way, the influence of lateral force can be made small in the state which hung the water tank 20, and the water tank 20 can be maintained in the stable state.

また、図１２に示したように、吊り棒４０を水槽２０の前側と後側にそれぞれ２本づつ配置し、吊り棒２０の上部を筐体（後方可動ユニット３１も含む）に支持したものにおいて、水槽２０の前側に対応する筐体３０の２つの吊り棒支持部の間隔Ｙを、水槽２０の後側に対応する筐体３０の２つの吊り棒支持部の間隔Ｘより広くするのが好ましい。すなわち、本実施の形態の洗濯機のように、水槽２０後側の吊り棒４０を引き上げて水槽２０を傾斜させる洗濯機にあっては、水槽２０の上部が大きく前方へ傾斜し、水槽２０の前側部では水槽２０と吊り棒４０の距離が狭まる傾向にある。そこで、予め水槽２０の前側に対応する筐体３０の２つの吊り棒支持部の間隔を広くすることにより、水槽２０前側の２つの吊り棒４０の間隔を広く取ることができ、たとえ水槽２０の上部が前方に傾斜した場合であっても、水槽２０と吊り棒４０の距離を十分に確保することができる。その結果、水槽２０が吊り棒４０に接触して、吊り棒４０が曲がる等の事態の発生を未然に防止することができる。
また上記の観点から、水槽２０の前側の２つの継ぎ手部５０における各貫通穴５１の間隔Ｗ２を、水槽２０の後側の２つの継ぎ手部５０における各貫通穴５１の間隔Ｗ１より広くしておくのが好ましい。この場合においても、水槽２０前側の２つの吊り棒４０の間隔を広く取ることができ、たとえ水槽２０の上部が前方に傾斜した場合であっても、水槽２０と吊り棒４０の距離を十分に確保することができる。その結果、水槽２０が吊り棒４０に接触して、吊り棒４０が曲がる等の事態の発生を未然に防止することができる。 In addition, as shown in FIG. 12, two suspension rods 40 are arranged on the front side and the rear side of the water tank 20, respectively, and the upper part of the suspension rod 20 is supported by a housing (including the rear movable unit 31). The distance Y between the two suspension rod support portions of the housing 30 corresponding to the front side of the water tank 20 is preferably wider than the distance X between the two suspension rod support portions of the housing 30 corresponding to the rear side of the water tank 20. . That is, as in the washing machine of the present embodiment, in the washing machine that raises the suspension bar 40 on the rear side of the water tank 20 and tilts the water tank 20, the upper part of the water tank 20 is largely inclined forward, At the front side, the distance between the water tank 20 and the suspension rod 40 tends to be narrowed. Therefore, by widening the distance between the two suspension rod support portions of the housing 30 corresponding to the front side of the water tank 20 in advance, the distance between the two suspension bars 40 on the front side of the water tank 20 can be increased. Even when the upper portion is inclined forward, a sufficient distance between the water tank 20 and the suspension rod 40 can be secured. As a result, it is possible to prevent the water tank 20 from coming into contact with the suspension rod 40 and the suspension rod 40 from being bent.
Further, from the above viewpoint, the interval W2 between the through holes 51 in the two joint portions 50 on the front side of the water tank 20 is set larger than the interval W1 between the through holes 51 in the two joint portions 50 on the rear side of the water tank 20. Is preferred. Even in this case, the distance between the two hanging rods 40 on the front side of the water tank 20 can be widened, and even if the upper portion of the water tank 20 is inclined forward, the distance between the water tank 20 and the hanging rod 40 is sufficiently large. Can be secured. As a result, it is possible to prevent the water tank 20 from coming into contact with the suspension rod 40 and the suspension rod 40 from being bent.

図１３は水槽２０の下部と吊り棒４０の防振部３４を示す構成図である。ここでは、水槽２０の継ぎ手部５０より下側部分２０Ａを、その最下端に向かって狭まるテーパ形状としている。これにより、防振部３４が水槽２０の外周面に接触しないで傾斜できる範囲が広がるため、水槽２０をスムーズにより大きく傾斜させることができる。   FIG. 13 is a configuration diagram showing the lower part of the water tank 20 and the vibration isolator 34 of the hanging rod 40. Here, the lower portion 20 </ b> A from the joint portion 50 of the water tank 20 has a tapered shape that narrows toward the lowermost end. Thereby, since the range which can incline without the vibration isolator 34 contacting the outer peripheral surface of the water tank 20 spreads, the water tank 20 can be inclined more largely smoothly.

図１４、図１５は継ぎ手部５０と吊り棒４０の防振部３４を示す構成図である。
図１４は、継ぎ手部５０の貫通穴５１に連通する吊り棒導入路５２の形状を、下部が広く上部が狭いテーパ形状として、吊り棒４０を貫通穴５１に導入する際の作業性の向上を図ったものである。 14 and 15 are configuration diagrams showing the joint portion 50 and the vibration isolating portion 34 of the hanging rod 40. FIG.
FIG. 14 shows that the shape of the suspension rod introduction path 52 communicating with the through hole 51 of the joint portion 50 is a tapered shape with a wide lower portion and a narrow upper portion, thereby improving workability when the suspension rod 40 is introduced into the through hole 51. It is intended.

図１５は、継ぎ手部５０に、複数のリブ５０Ａ，５０Ｂを設け、継ぎ手部５０の強度を補強するようにしたものである。なお、これらのリブは、かならずしも左右対称または上下対称に配置する必要はない。すなわち、防振部３４の傾斜態様を考慮して、リブは防振部３４の傾斜の障害とならないように配置するのが前提であり、したがって、左右非対称または上下非対称の配置となってもよい。たとえば、継ぎ手部５０を構成するリブのうち、前側のリブより後側のリブを上下に長くすると、水槽２０と防振部３４との接触を回避しやすくなり、強度も高めることができる。
また、防振部３４の外周に弾性部材４２を配置すると、防振部３４が傾斜してその側面が継ぎ手部５０に接触した場合に、接触による衝撃の緩和が図れる。弾性部材４２は、水槽２０と吊り棒４０が揺動して、水槽２０と防振部３４とが接触する場合に、その揺動に起因してそれらが最初に接触する部分に少なくとも配置する。これにより、部品の損傷を防止できるとともに、振動や騒音も抑制できる。 In FIG. 15, the joint portion 50 is provided with a plurality of ribs 50 </ b> A and 50 </ b> B to reinforce the strength of the joint portion 50. Note that these ribs are not necessarily arranged symmetrically or vertically. That is, in consideration of the inclination of the vibration isolator 34, the ribs are premised to be arranged so as not to obstruct the inclination of the vibration isolator 34. Therefore, the rib may be asymmetrical or vertically asymmetric. . For example, among the ribs constituting the joint portion 50, when the rear rib is made longer than the front rib, it is easy to avoid contact between the water tank 20 and the vibration isolator 34, and the strength can be increased.
Further, when the elastic member 42 is disposed on the outer periphery of the vibration isolator 34, when the vibration isolator 34 is inclined and the side surface thereof contacts the joint portion 50, the impact caused by the contact can be reduced. When the water tank 20 and the suspension rod 40 are swung and the water tank 20 and the vibration isolator 34 are in contact with each other, the elastic member 42 is disposed at least at a portion where they first contact due to the rocking. Thereby, while being able to prevent damage to components, vibration and noise can also be suppressed.

図１６は継ぎ手部５０の貫通孔５１と防振部３４の継ぎ手部５０との対向部とを示す模式図である。既に説明してきたように、継ぎ手部５０の貫通孔５１は、洗濯機の略前後方向に長い長穴なっている。そして、水槽２０が直立状態の時は、吊り棒４０が貫通孔５１のほぼ中央部に位置するようになっており、そのときの防振部３４の継ぎ手部５０との対向部は、図１６の実線と波線からなる外側の円形状の位置にある。このため、防振部３４の継ぎ手部５０との対向部は、貫通穴５１の周縁部と重なりあい、吊り棒４０と継ぎ手部５０とが適切な連結状態を保つことができる。   FIG. 16 is a schematic diagram showing a through hole 51 of the joint portion 50 and a facing portion of the vibration isolation portion 34 facing the joint portion 50. As already described, the through hole 51 of the joint portion 50 is a long hole substantially in the front-rear direction of the washing machine. When the water tank 20 is in an upright state, the suspension bar 40 is positioned at the substantially central portion of the through hole 51, and the portion of the vibration isolator 34 facing the joint portion 50 is as shown in FIG. It is in the position of the outer circular shape consisting of the solid line and the wavy line. For this reason, the opposing part with the joint part 50 of the vibration isolator 34 overlaps with the peripheral part of the through-hole 51, and the suspension bar 40 and the joint part 50 can maintain a suitable connection state.

これに対して、水槽２０の傾斜角度によっては、吊り棒４０が貫通孔５１の一端に来る場合がある。その場合、防振部３４の継ぎ手部５０との対向部は、例えば、図１６の黒点で表した領域に来ることが予想される。しかしながら、そのような場合にあっても、貫通穴５１の他端側で、防振部３４の継ぎ手部５０との対向部が、該貫通穴５１の周縁部と重なりあう大きさとなるようにするのが好ましい。これは、防振部３４の継ぎ手部５０との対向部が、貫通穴５１に嵌って引っ掛かってしまうのを回避するためである。   On the other hand, depending on the inclination angle of the water tank 20, the hanging rod 40 may come to one end of the through hole 51. In that case, it is expected that the portion of the vibration isolator 34 that faces the joint portion 50 comes, for example, in the region represented by the black dots in FIG. However, even in such a case, on the other end side of the through hole 51, the portion facing the joint portion 50 of the vibration isolating portion 34 has a size that overlaps with the peripheral portion of the through hole 51. Is preferred. This is to avoid the portion of the vibration isolator 34 facing the joint portion 50 from being caught in the through hole 51.
