Description

本発明は、洗濯，脱水を行うドラム式洗濯機及び洗濯，脱水及び乾燥を行うドラム式洗濯乾燥機に係る。   The present invention relates to a drum type washing machine that performs washing and dehydration and a drum type washing and drying machine that performs washing, dehydration and drying.

ドラム式洗濯機は，筐体が水を溜める外槽を内包し，外槽が衣類を投入するドラムを内包している。ドラム式洗濯機は，洗いと，すすぎと，脱水の各工程を行う。脱水時に衣類が片寄った状態で，ドラムが高速回転すると大きな遠心力が発生し，大きな振動となる。この大きな振動を小さくするために，外槽の下部はばねやダンパで構成されるサスペンションで支持されている。また，外槽の前後方向への倒れ込みを防ぐために，引張りばねの様な弾性部材で外槽の上部と筐体を接続して，外槽を前後に支持している。ドラム式洗濯機の弾性部材のばね定数が大きくなると，共振回転速度が上昇して，遠心力が大きくなるため，ドラムから外槽に加わる加振力が大きくなり，外槽の振動が大きくなる。外槽の振動が大きくなると，外槽から筺体に振動が伝達しやすくなり，筺体の振動が増加することで不快感が増す。そのため，外槽の上部を支持する弾性部材は，設置空間を確保して，所定のばね定数によって，外槽の支持と振動の抑制を両立している。   In the drum type washing machine, the casing contains an outer tub for storing water, and the outer tub contains a drum for putting clothes. A drum-type washing machine performs washing, rinsing, and dewatering processes. When the drum rotates at a high speed with the clothes on its side during dehydration, a large centrifugal force is generated and a large vibration occurs. In order to reduce this large vibration, the lower part of the outer tub is supported by a suspension composed of springs and dampers. In addition, in order to prevent the outer tank from falling in the front-rear direction, the upper part of the outer tank and the housing are connected by an elastic member such as a tension spring to support the outer tank in the front-rear direction. When the spring constant of the elastic member of the drum type washing machine increases, the resonance rotational speed increases and the centrifugal force increases, so the excitation force applied from the drum to the outer tub increases and the vibration of the outer tub increases. When the vibration of the outer tub increases, it becomes easier to transmit the vibration from the outer tub to the housing, and the discomfort increases by increasing the vibration of the housing. Therefore, the elastic member that supports the upper portion of the outer tub secures an installation space and achieves both the support of the outer tub and the suppression of vibration by a predetermined spring constant.

外槽の上部を支持する弾性部材の従来技術には，特開２０１４−３３７４９号公報（特許文献１）がある。この公報には，外槽の上部を前後方向に支持する二組の懸架手段を有するドラム式洗濯機において，第一の懸架手段は前記外槽を前方かつ上方へ向けて懸架し，前記第一の懸架手段の筺体との接続部は前記ドラムの前端の面よりも後方に位置し，第二の懸架手段は前記外槽を後方かつ上方へ向けて懸架し，前記第二の懸架手段の前記筺体との接続部は前記ドラムの後端の面よりも前方に位置し，前記第二の懸架手段の前記筺体との接続部は，前記第一の懸架手段の前記外槽との接続部よりも後方に位置させると記載されている。また，特開２００２−３４６２８２号公報（特許文献２）には，外槽の上部では，引張りばねを介して筐体の天板に補助的に弾性支持されていると記載されている。   Japanese Unexamined Patent Application Publication No. 2014-33749 (Patent Document 1) is known as a prior art of an elastic member that supports the upper part of the outer tub. In this publication, in a drum type washing machine having two sets of suspension means for supporting the upper part of the outer tub in the front-rear direction, the first suspension means suspends the outer tub forward and upward, The connecting portion of the suspension means with the housing is located behind the front end surface of the drum, the second suspension means suspends the outer tub rearward and upward, and the second suspension means The connecting portion with the housing is located in front of the rear end surface of the drum, and the connecting portion with the housing of the second suspension means is connected with the outer tank of the first suspension means. Is also described as being located rearward. Japanese Patent Laid-Open No. 2002-346282 (Patent Document 2) describes that the upper portion of the outer tub is elastically supported by the top plate of the housing via a tension spring.

特開２０１４−３３７４９号公報JP 2014-33749 A 特開２００２−３４６２８２号公報JP 2002-346282 A

特許文献１は，第一の懸架手段で外槽を前方かつ上方へ向けて懸架し，第二の懸架手段で外槽を後方かつ上方へ向けて懸架している。洗濯容量の大容量化で外槽の径が拡大すると，外槽と筐体の上下空間が狭くなり，懸架手段の設置空間が狭くなるため，懸架手段を設置することが困難となる。特許文献２は，懸架手段となる引張りばねのコイル部が外槽の径が最大となる部分の上方に位置しているため，洗濯容量の大容量化で外槽の径が拡大すると，外槽と懸架手段の上下空間狭くなり，外槽が大きく振動した際に外槽とコイル部が干渉して，異音が発生する。外槽とコイル部の干渉を防ぐために，外槽の懸架手段の接続部を上方に伸ばして，外槽とコイル部の上下空間を確保した場合，大容量化で外槽と筐体の上下空間が狭くなっているため，外槽が大きく振動した際に，外槽の懸架手段の接続部と筐体が干渉して異音が発生する。   In Patent Document 1, the outer tank is suspended forward and upward by the first suspension means, and the outer tank is suspended rearward and upward by the second suspension means. If the diameter of the outer tub is increased by increasing the washing capacity, the vertical space between the outer tub and the casing is reduced, and the installation space for the suspension means is reduced, so that it is difficult to install the suspension means. In Patent Document 2, since the coil portion of the tension spring serving as a suspension means is located above the portion where the diameter of the outer tub is maximum, if the diameter of the outer tub is increased by increasing the washing capacity, The space above and below the suspension means becomes narrow, and when the outer tank vibrates greatly, the outer tank and the coil part interfere with each other, generating abnormal noise. In order to prevent interference between the outer tub and the coil section, the connecting part of the suspension means of the outer tub is extended upward to secure the upper and lower spaces between the outer tub and the coil section. Therefore, when the outer tub vibrates greatly, the connection part of the suspension means of the outer tub and the housing interfere with each other, and noise is generated.

また，特許文献１と特許文献２では，外槽が大きく振動し，懸架手段である引張ばねが圧縮方向に大きく変形する場合，懸架手段が自然長となり，引張力がなくなる。この状態で，更に外槽が振動すると，懸架手段に引張力がないため，懸架手段が接続部から外れて，外槽が倒れ込んでしまう。外槽が倒れ込むと，外槽が筺体と衝突し続けることで，異音が発生する。   In Patent Document 1 and Patent Document 2, when the outer tub vibrates greatly and the tension spring as the suspension means is greatly deformed in the compression direction, the suspension means has a natural length and the tensile force is lost. If the outer tub further vibrates in this state, the suspension means does not have a tensile force, so that the suspending means is detached from the connecting portion and the outer tub falls. When the outer tank falls down, the outer tank keeps colliding with the housing, and noise is generated.

本発明は上記課題を解決する手段の一例を挙げるならば，回転軸が水平または，奥側が下になるように傾斜した回転自在なるドラムと，該ドラムを内包すると共に洗濯水を溜める外槽と，該外槽を内包する筺体とを有し，前記外槽の上部を前後方向に支持する少なくとも二組の懸架手段を有するドラム式洗濯機において，第一の懸架手段は，前記外槽を前方かつ上方へ向けて懸架し，前記第一の懸架手段のコイル部は，前記外槽の径が最大となる部分よりも前方に位置し，第二の懸架手段は，前記第一の懸架手段よりも後方に位置し，前記第二の懸架手段の前記外槽との接続部は，前記第一の懸架手段の前記外槽との接続部よりも後方に位置し，前記第二の懸架手段の前記筐体との接続部は，前記第二の懸架手段の前記外槽との接続部より後方に位置することを特徴とするドラム式洗濯機及びドラム式洗濯乾燥機。   If the present invention gives an example of means for solving the above-mentioned problems, a rotatable drum whose rotation axis is horizontal or inclined so that the back side is down, an outer tub containing the drum and storing washing water, , A drum-type washing machine having a housing containing the outer tub and having at least two sets of suspension means for supporting the upper part of the outer tub in the front-rear direction. And the coil portion of the first suspension means is located in front of the portion where the diameter of the outer tub is maximized, and the second suspension means is more than the first suspension means. Is located rearward, and the connection portion of the second suspension means with the outer tub is located behind the connection portion of the first suspension means with the outer tub, and the second suspension means The connecting portion with the casing is behind the connecting portion with the outer tub of the second suspension means. Drum type washing machine and a drum-type washing and drying machine, characterized in that located.

本発明によれば，洗濯容量の大容量化で外槽の径が拡大した場合に，外槽の懸架手段の設置空間を確保することができ，外槽と懸架手段のコイル部が干渉することで発生する異音を防止し，また，外槽の懸架手段が接続部から外れるのを防止して，外槽が倒れ込んで筺体と衝突して発生する異音を防止するドラム式洗濯機及びドラム式洗濯乾燥機を提供することができる。   According to the present invention, when the diameter of the outer tub is increased by increasing the washing capacity, the installation space for the suspension means of the outer tub can be secured, and the coil part of the outer tub and the suspension means can interfere with each other. Drum type washing machine and drum which prevent abnormal noise generated by the outer tub falling and colliding with the casing by preventing the abnormal noise generated in the tank and preventing the suspension means of the outer tub from coming off from the connection part A type washing dryer can be provided.

外槽１１には，給水弁１５ならびに洗剤容器１２を介して給水ホース１７の一端を接続している。給水弁１５を開くことで，給水ホース接続口３０から外槽１１内に洗濯水の供給を行う。   One end of a water supply hose 17 is connected to the outer tub 11 via a water supply valve 15 and a detergent container 12. By opening the water supply valve 15, washing water is supplied from the water supply hose connection port 30 into the outer tub 11.

外槽１１の下部に備えられた排水ホース１４は排水経路に循環ポンプ２７，糸屑フィルタ２８，排水弁１４ａが設けてあり，排水弁１４ａを閉じて給水することで外槽１１に洗濯水を溜め，排水弁１４ａを開いて外槽１１内の洗濯水を機外へ排水する。   The drainage hose 14 provided in the lower part of the outer tub 11 is provided with a circulation pump 27, a lint filter 28, and a drainage valve 14a in the drainage path. Washing water is supplied to the outer tub 11 by closing the drainage valve 14a and supplying water. The drainage valve 14a is opened and the washing water in the outer tub 11 is drained out of the machine.

外槽１１の下方には，外槽１１の振動振幅を検知する振動センサ１８が備えられており，振動センサ１８の値が予め設定した所定値を超えると，脱水運転を停止する。   A vibration sensor 18 for detecting the vibration amplitude of the outer tub 11 is provided below the outer tub 11, and the dehydration operation is stopped when the value of the vibration sensor 18 exceeds a predetermined value.

上記構成において，ドラム式洗濯機１００の動作を説明する。電源スイッチ４を押すと，ドラム式洗濯機１００が起動する。ドア開放取手２ａを引いて，ドア２を開いてドラム２１内に衣類を投入し，ドア２を閉じた後，操作スイッチ５を操作することで，運転を開始する。運転を開始すると，ドラム２１が回転して，注水前の衣類の重量を算出する。尚，モータ２２の回転速度と電流値に基づいて，ドラム２１内の衣類の重量を算出する。算出した衣類の重量に基づいて，投入する洗剤量を表示器６に表示する。洗剤容器１２内に所定量の洗剤量を投入後，初めに洗い工程を開始する。洗い工程において，給水弁１５を開いて，給水ホース接続口３０から供給した水を給水ホース１７ならびに洗剤容器１２を介して，洗剤と共に外槽１１内に給水する。この時，循環ポンプ２７内で未溶解の洗剤と水が強力に撹拌され，効率よく洗剤を溶かし，高濃度の洗剤液を生成することができる。この動作を所定時間実行した後，ドラム２１が正転，停止，逆転，停止を繰り返す洗い動作を所定時間行う。このとき，衣類がバッフル２３によって持ち上げられ落下する。洗い工程を行った後，脱水工程を実行する。まず，排水弁１４ａを開いて，外槽１１内の水が排水ホース１４を介してドラム式洗濯機１００の外に排水する。次に，衣類のドラム２１の内周面への張り付け動作を行う。ドラム２１を低速回転数（例えば６０ｒ／ｍｉｎ）で一方向に回転させ，洗い工程で水を含んだ衣類をドラム２１の回転時にバッフル２３によって持ち上げ，落下する際にドラム２１の内周面に広げる。次に，ドラム２１の回転速度を徐々に上昇させて，ドラム２１の内周面に衣類を張り付かせる。衣類がドラム２１の内周面に張り付くと，ドラム２１の回転速度を徐々に上昇させて，外槽１１や筐体１の共振回転速度を通過しながら，ドラム２１が所定回転数（例えば，９００ｒ／ｍｉｎ）に到達する。その後，ドラム２１が所定時間回転することで，衣類に含まれる水を遠心脱水する。   In the above configuration, the operation of the drum type washing machine 100 will be described. When the power switch 4 is pressed, the drum type washing machine 100 is activated. The door opening handle 2a is pulled, the door 2 is opened, clothes are put into the drum 21, the door 2 is closed, and then the operation switch 5 is operated to start operation. When the operation is started, the drum 21 rotates to calculate the weight of the clothes before water injection. The weight of the clothing in the drum 21 is calculated based on the rotation speed of the motor 22 and the current value. Based on the calculated weight of clothing, the amount of detergent to be added is displayed on the display 6. After putting a predetermined amount of detergent into the detergent container 12, the washing process is started first. In the washing process, the water supply valve 15 is opened, and the water supplied from the water supply hose connection port 30 is supplied into the outer tub 11 together with the detergent through the water supply hose 17 and the detergent container 12. At this time, undissolved detergent and water are vigorously stirred in the circulation pump 27, so that the detergent can be dissolved efficiently and a high-concentration detergent liquid can be generated. After this operation is performed for a predetermined time, a washing operation in which the drum 21 repeats forward rotation, stop, reverse rotation, and stop is performed for a predetermined time. At this time, the clothes are lifted and dropped by the baffle 23. After the washing process, the dehydration process is performed. First, the drain valve 14 a is opened, and the water in the outer tub 11 drains out of the drum type washing machine 100 through the drain hose 14. Next, an operation of attaching clothing to the inner peripheral surface of the drum 21 is performed. The drum 21 is rotated in one direction at a low speed (for example, 60 r / min), and the clothes containing water are lifted by the baffle 23 when the drum 21 is rotated in the washing process, and spread on the inner peripheral surface of the drum 21 when falling. . Next, the rotational speed of the drum 21 is gradually increased, and clothes are attached to the inner peripheral surface of the drum 21. When the clothing sticks to the inner peripheral surface of the drum 21, the drum 21 gradually increases in rotational speed and passes through the resonant rotational speed of the outer tub 11 or the housing 1 while the drum 21 rotates at a predetermined rotational speed (for example, 900 r). / Min). Thereafter, the drum 21 rotates for a predetermined time, so that water contained in the clothes is centrifugally dehydrated.

なお，ドラム２１の内周面に張り付いた衣類が片寄っていると，ドラム２１の回転速度の脈動（回転変動）や外槽１１の共振回転速度時に外槽１１の振動振幅が大きくなる。ドラム２１の回転変動や外槽１１の振動振幅を検出している振動センサ１８の値が所定の値よりも大きい場合は，アンバランスを小さくするために，脱水運転を停止して，ドラム２１を正転と逆転を繰り返すほぐし動作や，注水を行い，衣類の片寄りを修正する。   In addition, if the clothes stuck to the inner peripheral surface of the drum 21 are offset, the vibration amplitude of the outer tub 11 becomes large at the pulsation (rotational fluctuation) of the rotational speed of the drum 21 or the resonance rotational speed of the outer tub 11. When the value of the vibration sensor 18 that detects the rotational fluctuation of the drum 21 and the vibration amplitude of the outer tub 11 is larger than a predetermined value, the dehydration operation is stopped and the drum 21 is moved to reduce the unbalance. Perform loosening operation that repeats normal rotation and reverse rotation and water injection to correct the displacement of clothing.

この脱水工程を行った後，給水弁１５を開いて，給水ホース接続口３０から供給した水を給水ホース１７ならびに洗剤容器１２を介して，洗剤と共に外槽１１内に給水する。外槽１１内に給水を行った後，すすぎ工程を行う。このすすぎ工程においては，前述した洗い工程と同様に，ドラム２１が正転，停止，反転，停止の動作を繰り返す。このとき，バッフル２３によって持ち上げられた衣類が落下する攪拌動作を繰り返す，すすぎ動作を所定時間行う。   After performing this dehydration step, the water supply valve 15 is opened, and the water supplied from the water supply hose connection port 30 is supplied into the outer tub 11 together with the detergent through the water supply hose 17 and the detergent container 12. After supplying water into the outer tub 11, a rinsing step is performed. In this rinsing step, the drum 21 repeats forward, stop, reverse, and stop operations in the same manner as the washing step described above. At this time, the rinsing operation is repeated for a predetermined time, in which the stirring operation in which the clothes lifted by the baffle 23 is dropped is repeated.

その後，前述した脱水工程およびすすぎ工程を所定回数繰り返し，最終脱水工程に移行する。この最終脱水工程における脱水時間は，前述の脱水工程より長く設定してある。   Thereafter, the dehydration process and the rinsing process described above are repeated a predetermined number of times, and the process proceeds to the final dehydration process. The dehydration time in this final dehydration step is set longer than that in the above dehydration step.

ドラム式洗濯乾燥機は，ドラム式洗濯機１００に温風ヒータ，温風ファンなどを備え（いずれも図示せず），最終脱水工程後に，洗い時よりもさらに低速で洗濯乾燥ドラムを回転させながら，温風を衣類に吹き付けて，衣類を乾燥する。   The drum-type washing / drying machine is equipped with a hot-air heater, a hot-air fan, etc. (both not shown) in the drum-type washing machine 100, and after the final dehydration process, the washing / drying drum is rotated at a lower speed than during washing. , Blow warm air on the clothing and dry the clothing.

次に，本実施の形態例において，洗濯容量の大容量化で外槽１１の最大径Ｄ１が拡大した場合に，外槽１１の第一の懸架手段８の設置空間を確保することができる第一の懸架手段８の詳細を図２と図３を用いて説明する。   Next, in the present embodiment, when the maximum diameter D1 of the outer tub 11 is increased by increasing the washing capacity, the installation space for the first suspension means 8 of the outer tub 11 can be secured. Details of one suspension means 8 will be described with reference to FIGS.

第一の懸架手段８は，コイル部８ａと外槽側のフック部８ｂと筐体側のフック部８ｃで構成されている。第一の懸架手段８の外槽側のフック部８ｂを外槽１１と接続するための外槽側前ホルダー１０ａは，外槽１１の最大径Ｄ１となる部分Ｌ１よりも前方の外槽１１のテーパー部にねじ（図示せず）で固定されている。なお，第一の懸架手段８と第二の懸架手段９は，外槽１１が前方や後方に振動した際に，伸縮するエラストマーや合成ゴム材料を用いても良い。また，第一の懸架手段８と第二の懸架手段９を外槽１１や筺体１に接続するために，ねじを用いて固定しても良い。   The first suspension means 8 includes a coil portion 8a, a hook portion 8b on the outer tub side, and a hook portion 8c on the housing side. The outer tank side front holder 10a for connecting the hook part 8b on the outer tank side of the first suspension means 8 to the outer tank 11 is provided on the outer tank 11 in front of the portion L1 having the maximum diameter D1 of the outer tank 11. It is fixed to the taper part with a screw (not shown). The first suspension means 8 and the second suspension means 9 may be made of an elastomer or synthetic rubber material that expands and contracts when the outer tub 11 vibrates forward or backward. Moreover, in order to connect the 1st suspension means 8 and the 2nd suspension means 9 to the outer tank 11 or the housing 1, you may fix using a screw.

外槽側前ホルダー１０ａを外槽１１のテーパー部に固定することで，コイル部８ａが外槽１１の最大径Ｄ１となる部分Ｌ１よりも前方とすることができ，外槽１１とコイル部８ａの上下空間及び筺体１と外槽側前ホルダー１０ａの上下空間を確保することができる。従って，洗濯容量の大容量化で外槽１１の径が拡大し，外槽１１と筺体1の上下空間が狭くなった場合においても，外槽１１が振動した際に，コイル部８ａと外槽１１の干渉の防止や，筺体１と外槽側前ホルダー１０ａの干渉の防止をすることができ，異音の発生を防止できる。   By fixing the outer tank side front holder 10a to the taper part of the outer tank 11, the coil part 8a can be placed in front of the portion L1 having the maximum diameter D1 of the outer tank 11, and the outer tank 11 and the coil part 8a. And the vertical space of the housing 1 and the outer tank side front holder 10a can be secured. Therefore, even when the diameter of the outer tub 11 is increased due to the increase in the washing capacity, and the vertical space between the outer tub 11 and the housing 1 is narrowed, when the outer tub 11 vibrates, the coil portion 8a and the outer tub 11 can be prevented, and the casing 1 and the outer tank side front holder 10a can be prevented from interfering with each other.

また，前述した様に，外槽１１の径が拡大した場合においても，第一の懸架手段８の上下方向の設置空間を確保することができる。そのため，第一の懸架手段８は外槽１１の径が拡大前と拡大後でコイル部を同一形状とすることができ，第一の懸架手段８のばね定数が大きくなることを避けられることにより，共振回転速度の上昇を防げる。共振回転速度の上昇を防ぐことで，外槽１１の共振時にドラム２１から外槽１１に加わる遠心力による加振力を低減できるので，外槽１１の振動振幅の増大を抑制でき，外槽１１から筐体１への伝達による筐体１の振動振幅が増大することを抑制できるので，使用者の不快感を抑制できる。   Further, as described above, even when the diameter of the outer tub 11 is enlarged, the installation space in the vertical direction of the first suspension means 8 can be secured. For this reason, the first suspension means 8 can have the same coil shape before and after the diameter of the outer tub 11 is expanded, and the spring constant of the first suspension means 8 can be avoided from increasing. , Prevents increase in resonance rotation speed. By preventing the resonance rotational speed from increasing, the excitation force due to the centrifugal force applied from the drum 21 to the outer tub 11 when the outer tub 11 resonates can be reduced, so that the increase in the vibration amplitude of the outer tub 11 can be suppressed. Since it can suppress that the vibration amplitude of the housing | casing 1 by transmission to the housing | casing 1 increases, a user's discomfort can be suppressed.

なお，本実施の形態例に示す懸架手段は，ドラム式洗濯乾燥機にも適用できる。   Note that the suspension means shown in this embodiment can also be applied to a drum-type washing and drying machine.

（実施例２）
次に実施例２について図４，図５，図６，図７，図８及び図９を参照して詳細に説明する。 (Example 2)
Next, the second embodiment will be described in detail with reference to FIGS. 4, 5, 6, 7, 8 and 9.

なお，ドラム式洗濯機１００については，実施例１と基本的に同様な構成であるので，以下では，異なる部分について説明する。   Since the drum type washing machine 100 has basically the same configuration as that of the first embodiment, different parts will be described below.

図４は本実施例のドラム式洗濯機１００の中央断面図を示し，図５は外槽１１が静態支持されている状態を示す。実施例２では，外槽側後ばねホルダー１０ｃの前方に外槽側外れ防止部材３１，外槽側外れ防止部材３１の前方に筐体側外れ防止部材３１ａを配置している。外槽側外れ防止部材３１と筐体側外れ防止部材３１ａ間は，外槽１１を静態支持している状態から，外槽１１が前方に移動して，第一の懸架手段８が自然長となる前または，自然長となった時に互いが干渉する距離となっている。外槽側外れ防止部材３１と筐体側外れ防止部材３１ａの高さは，外槽１１が前方向に大きく振動した際に互いが干渉する高さとなっている。   4 shows a central sectional view of the drum type washing machine 100 of the present embodiment, and FIG. 5 shows a state where the outer tub 11 is supported in a static state. In the second embodiment, the outer tub side detachment preventing member 31 is disposed in front of the outer tub side rear spring holder 10c, and the housing side detachment preventing member 31a is disposed in front of the outer tub side detachment preventing member 31. Between the outer tub side detachment preventing member 31 and the housing side detachment preventing member 31a, the outer tub 11 moves forward from the state in which the outer tub 11 is statically supported, and the first suspension means 8 has a natural length. It is the distance that interferes with each other when it becomes the previous or natural length. The height of the outer tub side detachment preventing member 31 and the case side detachment preventing member 31a is such that the outer tub 11 interferes with each other when it vibrates greatly in the forward direction.

外槽１１が静態支持されている状態は，フック方式の第一の懸架手段８と第二の懸架手段９を引っ張った状態で外槽１１に接続して，第一の懸架手段と第二の懸架手段が外槽１１の前後でつり合った状態となるため，第一の懸架手段８と第二の懸架手段９の長さが自然長よりも長い。   The state in which the outer tub 11 is statically supported is connected to the outer tub 11 with the hook-type first suspension means 8 and the second suspension means 9 pulled, and the first suspension means and the second suspension means 9 are connected. Since the suspension means is balanced before and after the outer tub 11, the lengths of the first suspension means 8 and the second suspension means 9 are longer than the natural length.

実施例１や特許文献１に記載している様に，第一の懸架手段８で外槽１１を前方かつ上方に向けて懸架している場合，外槽１１が前方向に大きく振動すると，第一の懸架手段８は縮み，第二の懸架手段９は引っ張られて伸びる。外槽１１の前方向への振動がより大きくなった場合，第一の懸架手段８の縮み量が増えて，第一の懸架手段８が自然長となり，引張力がなくなる。その状態で外槽１１が更に振動すると，第一の懸架手段８が第一の懸架手段８が筐体側前ばねホルダー１０や外槽側前ばねホルダー１０ａから外れて，外槽１１が倒れ込んで，外槽１１が筺体１と衝突して異音が発生する。   As described in Example 1 and Patent Document 1, when the outer tank 11 is suspended forward and upward by the first suspension means 8, if the outer tank 11 vibrates greatly in the forward direction, One suspension means 8 is contracted, and the second suspension means 9 is pulled and extended. When the forward vibration of the outer tub 11 becomes larger, the amount of contraction of the first suspension means 8 increases, and the first suspension means 8 becomes a natural length and the tensile force is lost. When the outer tub 11 further vibrates in this state, the first suspension means 8 is detached from the housing-side front spring holder 10 or the outer tub-side front spring holder 10a, and the outer tub 11 falls down. The outer tub 11 collides with the housing 1 to generate abnormal noise.

図６は外槽１１が前方向に大きく振動した状態を点線で示す。外槽側外れ防止部材３１と筐体側外れ防止部材３１ａは，第一の懸架手段８が自然長または自然長となる前の長さとなった時に，互いが干渉する距離となっている。そのため，第一の懸架手段８が自然長または，自然長となる前の長さになった時に，外槽１１の前方への振動が抑制される。従って，第一の懸架手段８が筐体側前ばねホルダー１０や外槽側前ばねホルダー１０ａから外れることを防止して，外槽１１が倒れ込みを防止することで，外槽１１と筺体１の衝突による異音の発生を防止できる。   FIG. 6 shows a state in which the outer tub 11 is greatly vibrated in the forward direction by dotted lines. The outer tub side detachment preventing member 31 and the housing side detachment preventing member 31a are distances at which the first suspension means 8 interfere with each other when the first suspending means 8 becomes the natural length or the length before the natural length. Therefore, when the first suspension means 8 has a natural length or a length before the natural length, the forward vibration of the outer tub 11 is suppressed. Accordingly, the first suspension means 8 is prevented from being detached from the housing-side front spring holder 10 or the outer tub-side front spring holder 10a, and the outer tub 11 is prevented from falling, so that the outer tub 11 and the casing 1 collide with each other. It is possible to prevent the generation of abnormal noise.

第一の懸架手段８は，外槽１１が前後に倒れるのを防止するために，水平方向に所定の力が必要となる。ここで，実施例１や特許文献１の様に，外槽１１を第一の懸架手段８を前方かつ上方に懸架する場合，水平方向に所定の力を発生させると，第一の懸架手段８を水平に配置した時に比べて，第一の懸架手段８のばね定数が大きくなる。第一の懸架手段８のばね定数が大きくなると、共振回転速度が上昇して，遠心力が大きくなることで，外槽１１の振動が大きくなる。外槽１１の振動が大きくなると，外槽１１の振動が筺体１に伝達して，筺体１の振動が大きくなり，不快感が増す。そのため，第一の懸架手段は水平に配置することが望ましい。   The first suspension means 8 requires a predetermined force in the horizontal direction to prevent the outer tub 11 from falling back and forth. Here, when the outer tank 11 is suspended forward and upward from the first suspension means 8 as in Example 1 or Patent Document 1, if a predetermined force is generated in the horizontal direction, the first suspension means 8 The spring constant of the first suspension means 8 is larger than when the are horizontally disposed. When the spring constant of the first suspension means 8 increases, the resonance rotational speed increases and the centrifugal force increases, so that the vibration of the outer tub 11 increases. When the vibration of the outer tub 11 is increased, the vibration of the outer tub 11 is transmitted to the housing 1 and the vibration of the housing 1 is increased, resulting in increased discomfort. Therefore, it is desirable to arrange the first suspension means horizontally.

図７は，特許文献２に記載している様に，第一の懸架手段８を水平方向に配置した状態を示す。   FIG. 7 shows a state in which the first suspension means 8 is arranged in the horizontal direction as described in Patent Document 2.

第一の懸架手段８を水平に配置する場合，外槽１１が前方に大きく振動すると，第一懸架手段８は水平方向に変形しやく，自然長となりやすいため，第一懸架手段８が筐体側前ばねホルダー１０や外槽側前ばねホルダー１０ａから外れて外槽１１が倒れ込みやすくなる。   When the first suspension means 8 is disposed horizontally, if the outer tub 11 vibrates greatly forward, the first suspension means 8 is easily deformed in the horizontal direction and tends to have a natural length. The outer tub 11 is easy to fall down by being detached from the front spring holder 10 and the outer tub side front spring holder 10a.

図８は，本実施の形態例に記載している外槽側外れ防止部材３１と筐体側外れ防止部材３１ａを図７に備えた状態を示す。第一の懸架手段８を水平方向に配置して，第一の懸架手段８が水平方向に変形しやすい場合においても，図９に示す様に，外槽側外れ防止部材３１と筐体側外れ防止部材３１ａが干渉することで，外槽１１の振動が抑制され，第一の懸架手段８を水平方向に配置した場合においても，第一の懸架手段８が筐体側前ばねホルダー１０や外槽側前ばねホルダー１０ａから外れることによる外槽１１の倒れ込みを防止することで，外槽１１と筺体１の衝突による異音の発生を防止できる。   FIG. 8 shows a state in which the outer tub side detachment preventing member 31 and the casing side detachment preventing member 31a described in the present embodiment are provided in FIG. Even when the first suspension means 8 is arranged in the horizontal direction and the first suspension means 8 is easily deformed in the horizontal direction, as shown in FIG. When the member 31a interferes, the vibration of the outer tub 11 is suppressed, and even when the first suspending means 8 is disposed in the horizontal direction, the first suspending means 8 can be connected to the housing-side front spring holder 10 or the outer tub side. By preventing the outer tub 11 from falling down due to detachment from the front spring holder 10a, it is possible to prevent the generation of noise due to the collision between the outer tub 11 and the housing 1.

従って，本実施の形態例に記載している外槽側外れ防止部材３１と筐体側外れ防止部材３１ａを備えることで，実施例１に記載している様な，外槽１１を前方かつ上方に向けて懸架している第一の懸架手段８を水平に配置することができる。第一の懸架手段８を水平に配置すると，第一の懸架手段８を前方かつ上方に向けて配置する場合に比べて，ばね定数を小さくできるので，共振回転速度の上昇を抑制して，外槽１１の振動が大きくなることを防止できるため，外槽１１から筺体１に伝達する振動を低減できる。   Therefore, by providing the outer tub side detachment preventing member 31 and the housing side detachment preventing member 31a described in the present embodiment, the outer tub 11 as described in the first embodiment is moved forward and upward. The first suspension means 8 suspended towards can be arranged horizontally. If the first suspension means 8 is disposed horizontally, the spring constant can be reduced as compared with the case where the first suspension means 8 is disposed forward and upward. Since it can prevent that the vibration of the tank 11 becomes large, the vibration transmitted to the housing 1 from the outer tank 11 can be reduced.

本発明により，第一の懸架手段８が筐体側前ばねホルダー１０や外槽側前ばねホルダー１０ａから外れて外槽１１が倒れ込むことを防止し，外槽１１と筺体１の衝突による異音の発生を防止できる。さらに第一の懸架手段８を水平に配置できるため，共振時に外槽１１から筺体１に伝達する振動を低減でき，筺体１の振動の増加を抑制することで不快感を低減できる。   According to the present invention, it is possible to prevent the first suspension means 8 from being detached from the housing-side front spring holder 10 or the outer tank-side front spring holder 10a and causing the outer tank 11 to fall down. Occurrence can be prevented. Furthermore, since the first suspension means 8 can be arranged horizontally, vibration transmitted from the outer tub 11 to the housing 1 during resonance can be reduced, and discomfort can be reduced by suppressing an increase in vibration of the housing 1.

なお，本実施の形態例に示す外れ防止部材は，ドラム式洗濯機１００とドラム式洗濯乾燥機に適用できる。   Note that the detachment prevention member shown in this embodiment can be applied to the drum type washing machine 100 and the drum type washing and drying machine.

また，モータ２２の後方の背面カバー１ｄに突起部４０を備え，モータ２２と突起部４０間は，第二の懸架手段９が外槽１１を静態支持している状態から，外槽１１が後方に移動して，第二の懸架手段９が自然長以下となる前に，モータ２２の背面が突起部材４０と干渉する位置とすることで，第二の懸架手段９が自然長に至る前に，外槽１１の後方向の振動が抑制されるため，第二の懸架手段９が外槽側後ばねホルダー１０ｃから外れることを防止できる（図４参照）。   Further, the rear cover 1d behind the motor 22 is provided with a protruding portion 40, and the outer tub 11 is located behind the motor 22 and the protruding portion 40 from the state where the second suspension means 9 statically supports the outer tub 11. Before the second suspension means 9 reaches the natural length before the second suspension means 9 reaches the natural length. Since the rearward vibration of the outer tub 11 is suppressed, the second suspension means 9 can be prevented from coming off from the outer tub side rear spring holder 10c (see FIG. 4).

さらに，本実施の形態例における外槽側外れ防止部材３１を外槽側後ばねホルダー１０ｃと同一の材料とすることで，外槽側外れ防止部材３１と外槽側後ばねホルダー１０ｃを一体部品として成型できる。同様に，筺体側外れ防止部材３１ａを筺体側後ばねホルダー１０ｂと同一材料とすることで，筺体側外れ防止部材３１ａを筺体側後ばねホルダー１０ｂと一体部品として成型できる。外れ防止部材とばねホルダーを一体部品とすることで，部品点数の増加を防ぎ，タクトタイム低減による生産コストの低減が可能となる。   Furthermore, by using the same material as the outer tub side rear spring holder 10c for the outer tub side detachment preventing member 31 in the present embodiment, the outer tub side detachment preventing member 31 and the outer tub side rear spring holder 10c are integrated parts. Can be molded as Similarly, by using the same material as the housing side rear spring holder 10b for the housing side separation preventing member 31a, the housing side separation preventing member 31a can be molded as an integral part with the housing side rear spring holder 10b. By making the detachment prevention member and the spring holder an integral part, it is possible to prevent an increase in the number of parts and reduce the production cost by reducing the tact time.
