Description

本発明は、乾燥運転における送風機の騒音低減を実現する洗濯乾燥機に関するものである。   The present invention relates to a washing / drying machine that realizes noise reduction of a blower in a drying operation.

従来、この種の洗濯乾燥機では、羽根車とそれを内包するケーシングと羽根車を回転させる駆動用モータで構成される送風機の、振動による騒音を低減させる構成が提案されてきた（例えば特許文献１参照）。   Conventionally, in this type of washer / dryer, a configuration has been proposed for reducing noise due to vibration of a blower that includes an impeller, a casing that includes the impeller, and a driving motor that rotates the impeller (for example, Patent Documents). 1).

図４は特許文献１に記載された従来の洗濯乾燥機の送風機の概略断面図を示すものである。   FIG. 4 shows a schematic cross-sectional view of a blower of a conventional washing and drying machine described in Patent Document 1.

図４において、羽根車１０１を内置するファンケース１０２と羽根車１０１を回す駆動用モータ１０３で構成され、ファンケース１０２の中央部位と駆動用モータ１０３の中央部位との間に介在する風漏れを防止するシール機能を有する中央防振ゴム１０４と、ファンケース１０２の外周側部位と駆動用モータ１０３の外周側部位との間に伝達を軽減する機能を要する外周防振ゴム１０５を備えている。また、中央防振ゴム１０４のゴム硬度を高く（３０〜５０度程度）することで、支持を安定させると共にケーシング１０２の気密性を保ち、外周防振ゴム１０５の硬度を低く（１０〜３０度程度）することで、駆動用モータ１０３からケーシング１０２への振動伝達をより軽減させるような構成となっている。   In FIG. 4, the fan case 102 in which the impeller 101 is placed and the driving motor 103 that rotates the impeller 101 are configured, and the wind leakage interposed between the central part of the fan case 102 and the central part of the driving motor 103 is prevented. A central anti-vibration rubber 104 having a sealing function to prevent and an outer anti-vibration rubber 105 that requires a function of reducing transmission between the outer peripheral side portion of the fan case 102 and the outer peripheral side portion of the driving motor 103 are provided. Further, by increasing the rubber hardness of the central anti-vibration rubber 104 (about 30 to 50 degrees), the support is stabilized and the airtightness of the casing 102 is maintained, and the hardness of the outer peripheral anti-vibration rubber 105 is decreased (10 to 30 degrees). The vibration transmission from the drive motor 103 to the casing 102 is further reduced.

特開２００９−７７７８２号公報JP 2009-77782 A

しかしながら、前記従来の構成では、支持の安定性および機密性を保つために中央防振ゴムの硬度を高くしているため、その部位からの振動伝達が大きくなってしまい、それにより騒音低減効果が不十分であるという課題があった。また、それを解消するためには、中央防振ゴムの柔軟性を向上させるような形状の工夫を行なったり、さらに外周防振ゴムに、低硬度にするための高価なシリコンゴム等を使用したりする必要があり、コストが高くなってしまうという課題があった。   However, in the conventional configuration, since the hardness of the central anti-vibration rubber is increased in order to maintain the stability and confidentiality of the support, the vibration transmission from the portion becomes large, and thus the noise reduction effect is obtained. There was a problem of being insufficient. In order to solve this problem, we devised a shape that would improve the flexibility of the central anti-vibration rubber, and also used expensive silicon rubber to reduce the hardness of the outer anti-vibration rubber. There was a problem that the cost would increase.

本発明は、前記従来の課題を解決するもので、低コストで、ケーシングの機密性を保ち、防振、防音性能を向上させた洗濯乾燥機の送風機を提供することを目的とする。   An object of the present invention is to solve the above-described conventional problems, and to provide a blower for a washing / drying machine that is low in cost, maintains confidentiality of a casing, and has improved vibration and sound insulation performance.

前記従来の課題を解決するために、本発明の洗濯乾燥機は、回転ドラムと、回転ドラムを内部に配設する水槽と、回転ドラムを回転駆動するモータと、水槽および回転ドラム内に乾燥用空気を送風し、羽根車と、羽根車を内包するケーシングと、羽根車を回転させる駆動用ファンモータで構成される送風機と、モータや送風機等を制御して洗い、すすぎ、脱水、乾燥の一連の行程を逐次制御する制御手段とを備え、送風機は、駆動用ファンモータの駆動軸をケーシング中央部に形成したケーシング孔に遊嵌させて、駆動用ファンモータとケーシングを固定し、ケーシングと駆動用ファンモータとの中央部に形成された隙間に中央シール部材を設け、中央シール部材は、ケーシングと駆動用ファンモータの半径方向で挟持されるように構成したものである。これにより、複雑な構成にすることなく、軸方向の振動伝達を低減することができ、ケーシングの気密性を保ちつつ、駆動時に比較的大きくなりやすく、振動音として、騒音増大に影響しやすい軸方向の振動と、騒音を低減することができる。   In order to solve the above-described conventional problems, a washing and drying machine of the present invention includes a rotating drum, a water tank in which the rotating drum is disposed, a motor that rotationally drives the rotating drum, a drying tank in the water tank and the rotating drum. A series of washing, rinsing, dehydration, and drying by controlling the motor and blower, etc., which blows air, controls the impeller, the casing that contains the impeller, and the fan motor for driving that rotates the impeller, and the motor and blower The blower is configured to loosely fit the drive shaft of the drive fan motor in a casing hole formed in the central portion of the casing to fix the drive fan motor and the casing, and to drive the casing. A central seal member is provided in a gap formed in the central portion of the fan motor for use, and the center seal member is configured to be sandwiched in the radial direction of the casing and the drive fan motor. Than is. This makes it possible to reduce axial vibration transmission without using a complicated configuration, while maintaining airtightness of the casing, the shaft tends to be relatively loud during driving, and is susceptible to noise increase as vibration noise. Directional vibration and noise can be reduced.

本発明の洗濯乾燥機は、低コストで、送風機の気密性を維持し、防振、防音性能を向上させるものである。   The washing / drying machine of the present invention is low-cost, maintains the airtightness of the blower, and improves vibration and sound insulation performance.

第１の発明は、有底円筒形に形成された回転ドラムと、前記回転ドラムを、開口する正面側から底部となる背面側に向けて回転軸方向が水平または水平方向から下向き傾斜となるようにして内部に配設する水槽と、前記回転ドラムを回転駆動するモータと、前記水槽および前記回転ドラム内に乾燥用空気を送風し、羽根車と、前記羽根車を内包するケーシングと、前記羽根車を回転させる駆動用ファンモータで構成される送風機と、前記モータや前記送風機等を制御して洗い、すすぎ、脱水、乾燥の一連の行程を逐次制御する制御手段とを備え、前記送風機は、前記駆動用ファンモータの駆動軸を前記ケーシング中央部に形成したケーシング孔に遊嵌させて、前記駆動用ファンモータと前記ケーシングを固定し、前記ケーシングと前記駆動用ファンモータとの中央部に形成された隙間に中央シール部材を設け、前記中央シール部材は、前記ケーシングと前記駆動用ファンモータの半径方向で挟持されるように構成したことにより、複雑な構成にすることなく、軸方向の振動伝達を低減することができ、ケーシングの気密性を保ちつつ、駆動時に比較的大きくなりやすく、振動音として、騒音増大に影響しやすい軸方向の振動を低減し、騒音を低減することができる。   According to a first aspect of the present invention, there is provided a rotating drum formed in a bottomed cylindrical shape, and the rotating drum is horizontally or downwardly inclined from the horizontal direction from the front side of the opening toward the back side of the bottom. A water tank disposed inside, a motor for rotating the rotary drum, an air for drying air in the water tank and the rotary drum, an impeller, a casing containing the impeller, and the blade A blower comprising a drive fan motor for rotating a car, and a control means for controlling the motor, the blower, etc. to wash, rinse, dewater, and dry sequentially, and the blower, The drive shaft of the drive fan motor is loosely fitted in a casing hole formed in the central portion of the casing, and the drive fan motor and the casing are fixed, and the casing and the drive A central seal member is provided in a gap formed at a central portion of the fan motor, and the central seal member is configured to be sandwiched in the radial direction of the casing and the driving fan motor, thereby forming a complicated configuration. Therefore, it is possible to reduce axial vibration transmission, maintain relatively tight airtightness of the casing, and become relatively loud during driving. Can be reduced.

第２の発明は、特に第１の発明において、中央シール部材は、ゴム材を主成分とした独立気泡型の発泡体としたことにより、ケーシングの気密性を維持しながらも、ＥＰＤＭやシリコンゴムなどから成る防振ゴムに比べて非常に柔軟であるため、駆動用ファンモータからの振動伝達をより軽減することができる。   In the second invention, in particular in the first invention, the center seal member is a closed-cell foam having a rubber material as a main component, so that the airtightness of the casing is maintained and EPDM or silicon rubber is maintained. Therefore, vibration transmission from the drive fan motor can be further reduced.

第３の発明は、特に、第１および第２の発明において、中央シール部材は、ケーシングの内周部に形成された段差部に、軸方向に接触するように装着したことにより、中央シール部材をより安定して保持することができ、かつ、シール部材は、ケーシングのみ軸方向に接触しているだけなので、軸方向に圧縮されることがなく、シール部材を通して、軸方向へ振動伝達することはほとんどないため、防振性能を維持しつつ、より安定してシール部材を保持することができる。   According to a third aspect of the invention, in particular, in the first and second aspects of the invention, the central seal member is mounted on the stepped portion formed on the inner peripheral portion of the casing so as to be in axial contact with the central seal member. Since the seal member is only in contact with the casing in the axial direction, the seal member is not compressed in the axial direction and transmits vibrations in the axial direction through the seal member. Therefore, the seal member can be held more stably while maintaining the vibration-proof performance.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。また、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description. Further, the present invention is not limited by this embodiment.

（実施の形態１）
図１は、本発明の第１の実施の形態における洗濯乾燥機の縦断面図である。 (Embodiment 1)
FIG. 1 is a longitudinal sectional view of a washing / drying machine according to a first embodiment of the present invention.

図１において、洗濯機本体５１の内部に揺動自在に水槽５２が配設され、水槽５２内には、回転ドラム５３が回転自在に配設され、回転ドラム５３は、水槽５２の背面に外側より取り付けられたモータ５４により回転駆動される。   In FIG. 1, a water tub 52 is swingably disposed inside a washing machine main body 51, and a rotary drum 53 is rotatably disposed in the water tub 52. It is rotationally driven by a motor 54 attached thereto.

また、本発明の洗濯乾燥機は、モード設定や制御プログラムに従い、図１に示すモータ５４、給水系５５、排水系５６、乾燥系５７などを自動制御して、少なくとも洗い行程、すすぎ行程、脱水行程、乾燥行程を行う機能を有したいわゆる洗濯乾燥機を構成している。   The washing / drying machine according to the present invention automatically controls the motor 54, the water supply system 55, the drainage system 56, the drying system 57, etc. shown in FIG. A so-called washing / drying machine having a function of performing a process and a drying process is configured.

給水系５５は、給水弁（図示せず）の開閉によって、給水経路７５を介して、実線矢印ａで示すように水槽５２内部に適時に給水でき、また給水を利用して洗剤収容部５８に使用者が予め投入しておいた洗剤を、水道水と共に水槽５２内に適時に投入できるようになっている。   The water supply system 55 can supply water into the water tank 52 in a timely manner as shown by a solid line arrow a through a water supply path 75 by opening and closing a water supply valve (not shown), and can be supplied to the detergent container 58 using the water supply. The detergent previously put in by the user can be put into the water tank 52 together with tap water in a timely manner.

排水系５６は、排水弁５９の開閉によって洗い行程終了時、すすぎ行程終了時など必要なときに一点鎖線矢印ｂで示すように、水槽５２の下部に形成された排水口７１に接続された排水管６０を介し、フィルターケース６７に内設され、糸屑類を捕集し外部から取り外し可能の排水フィルタ６１を通過した後、接続ホース７２、排水弁５９を経由して、機外に排水できるようになっている。なお、水槽５２の側壁内方下部には、排水口７１に排水されやすいように、排水溝７６が形成されている。   The drainage system 56 is a drainage connected to a drainage port 71 formed in the lower part of the water tank 52 as indicated by a one-dot chain line arrow b when necessary at the end of the washing process, the end of the rinsing process, etc. by opening and closing the drain valve 59. It is installed in the filter case 67 through the pipe 60, collects lint, passes through a drainage filter 61 that can be removed from the outside, and then drains out of the machine via a connection hose 72 and a drain valve 59. It is like that. A drainage groove 76 is formed at the inner lower part of the side wall of the water tank 52 so as to be easily drained to the drainage port 71.

回転ドラム５３は、略水平方向または水平方向から下向きに傾斜となるように配した回転軸６３により水槽５２の外底部に固着したモータ５４に直結され、回転駆動する事により、前方の開閉扉６４部より回転ドラム５３に投入された衣類の撹拌たたき洗いを行う。なお、開閉扉６４は、水槽５２の開口縁６５に装着したシール材６６を介して密閉し、また開くことができるようにしている。   The rotary drum 53 is directly connected to a motor 54 fixed to the outer bottom portion of the water tank 52 by a rotary shaft 63 arranged so as to be inclined substantially horizontally or downwardly from the horizontal direction. The clothes thrown into the rotating drum 53 from the section are stirred and washed. The open / close door 64 is sealed and opened through a sealing material 66 attached to the opening edge 65 of the water tank 52.

乾燥系５７は、水槽５２および回転ドラム５３内の空気を、駆動用ファンモータ３を有する送風機６２によって、図１の破線矢印ｃで示すように循環させる。乾燥系５７内には、糸屑類を捕集し除塵するフィルタ（図示せず）、除塵後の導入空気を除湿する除湿部（図示せず）、除湿後の空気を加熱して渇いた高温空気とする加熱部（図示せず）等を有する。   The drying system 57 circulates the air in the water tank 52 and the rotating drum 53 by the blower 62 having the driving fan motor 3 as shown by a broken line arrow c in FIG. In the drying system 57, a filter (not shown) that collects and removes dust from the yarns, a dehumidifying part (not shown) that dehumidifies the introduced air after dust removal, and a high temperature that is exhausted to heat the dehumidified air. It has a heating part (not shown) etc. used as air.

運転コース等のモードや各種機能の選択は、洗濯機本体５１の前面上部に設けられる操作パネル７３から入力して行い、制御手段７４がその入力情報を基に操作パネル７３上の表示手段（図示せず）で表示して使用者に知らせるとともに、操作パネル７３での入力設定手段（図示せず）により運転開始が設定されると、水槽５２内の水位を検知する水位検知手段（図示せず）等からのデータを入力して、モータ５４、排水弁５９、給水弁（図示せず）、駆動用ファンモータ３などの動作を制御し、洗い、すすぎ、脱水、乾燥行程などの運転を行う。   The mode such as the driving course and various functions are selected by inputting from the operation panel 73 provided at the upper front of the washing machine body 51, and the control means 74 displays the display means on the operation panel 73 based on the input information (FIG. When the operation start is set by an input setting means (not shown) on the operation panel 73, a water level detecting means (not shown) for detecting the water level in the water tank 52 is displayed. ) And the like, and the operation of the motor 54, drain valve 59, water supply valve (not shown), driving fan motor 3, etc. is controlled to perform operations such as washing, rinsing, dehydration, and drying processes. .

図２は、本発明の第１の実施の形態における洗濯乾燥機の送風機の概略断面図である。   FIG. 2 is a schematic cross-sectional view of the blower of the washing / drying machine according to the first embodiment of the present invention.

図２において、羽根車１は、ケーシング２に内包され、駆動用ファンモータ３は、駆動軸７をケーシング２中央部に設けたケーシング孔２ａに遊嵌させ、駆動軸７に羽根車１を取り付け、ケーシング２と駆動用ファンモータ３が直接接触することがないように、外周部を複数の防振体５を介して、ケーシング２に複数のビス６により固定している。   In FIG. 2, the impeller 1 is included in the casing 2, and the driving fan motor 3 loosely fits the driving shaft 7 in the casing hole 2 a provided in the central portion of the casing 2, and the impeller 1 is attached to the driving shaft 7. The outer peripheral portion is fixed to the casing 2 with a plurality of screws 6 via a plurality of vibration isolators 5 so that the casing 2 and the driving fan motor 3 do not directly contact each other.

また、駆動用ファンモータ３が駆動し、羽根車１が回転すると、外部の風が、二点鎖線矢印Ａのようにケーシング孔２ａからも吸い込まれるように流れようとするため、それを防止するために、ケーシング２と駆動用ファンモータ３の半径方向において、圧縮代４ａを持って挟持される中央シール部材４を設け、風の漏れを防いでいる。本発明では、中央シール部材４として、例えば、ＥＰＤＭなどのゴム材を主成分とし、独立気泡型に３〜３０倍に発泡させたシール性と柔軟性を備えた材料を使用している。   Further, when the driving fan motor 3 is driven and the impeller 1 rotates, the external wind tends to flow so as to be sucked from the casing hole 2a as indicated by a two-dot chain line arrow A, thereby preventing this. Therefore, in the radial direction of the casing 2 and the driving fan motor 3, a central seal member 4 is provided which is sandwiched with a compression allowance 4a to prevent wind leakage. In the present invention, the central seal member 4 is made of, for example, a material having a sealing property and flexibility that is made of a rubber material such as EPDM as a main component and foamed 3 to 30 times in an closed cell type.

以上のような構成において、送風時に駆動用ファンモータ３が駆動すると、羽根車１や駆動用ファンモータ３のアンバランスによる半径方向の振動と同時に、羽根車１の取付面での面ぶれ等により、軸方向の振動が発生する。   In the configuration as described above, when the driving fan motor 3 is driven at the time of blowing air, vibrations in the radial direction due to the imbalance of the impeller 1 and the driving fan motor 3 are caused by surface shake on the mounting surface of the impeller 1 and the like. An axial vibration occurs.

羽根車１の取付面での面ぶれが影響する、図２での実線矢印Ｂで表す軸方向の振動、つまり、取付面を中心とした回転するような振動の低減に対しては、取付面での平面度をさらに精度向上させるなどの必要があるが、コストも大きくなりやすい。しかし、この軸方向の振動が、送風機駆動時に振動音として、騒音を増大させる大きな要因となりやすいため、この軸方向の振動を低減させることは、送風機全体の振動、騒音低減に非常に重要である。   In order to reduce the vibration in the axial direction indicated by the solid arrow B in FIG. 2, that is, the vibration that rotates around the mounting surface, which is affected by the surface blurring on the mounting surface of the impeller 1, However, it is necessary to further improve the flatness of the film, but the cost tends to increase. However, since this axial vibration tends to be a major factor that increases noise as vibration noise when the blower is driven, it is very important to reduce this axial vibration to reduce the vibration and noise of the entire blower. .

軸方向の振動については、羽根車１の振動が、駆動用ファンモータ３の駆動軸７を介して、駆動用ファンモータ３に伝わり、駆動用ファンモータ３自身の振動と合わさって、防振体５を介した外周取付部および、中央部の中央シール部材４を介して、ケーシング２に伝わることによってケーシング２が振動し、それが振動音となって騒音が発生しようとする。   As for the vibration in the axial direction, the vibration of the impeller 1 is transmitted to the drive fan motor 3 via the drive shaft 7 of the drive fan motor 3 and is combined with the vibration of the drive fan motor 3 itself, so that the vibration isolator The casing 2 vibrates by being transmitted to the casing 2 through the outer peripheral attachment portion 5 and the central seal member 4 in the central portion, and this causes vibration noise to generate noise.

しかし、本発明の第１の実施の形態における中央シール部材４は、風漏れを防止する機能だけでなく、前述のように、ＥＰＤＭなどのゴム材を主成分とし、独立気泡型に３〜３０倍に発泡させた材料としており、さらに中央シール部材４は、ケーシング２と駆動用ファンモータ３の半径方向で圧縮挟持するように設けたことによって、送風機駆動時に大きくなりやすい軸方向の振動が、シール部材４を介して、ケーシング２に伝達する度合いを小さくすることができ、ケーシング２の振動からくる送風機の振動、騒音を、低コストで効果的に低減することができる。   However, the center seal member 4 according to the first embodiment of the present invention has not only a function of preventing wind leakage but also a rubber material such as EPDM as a main component as described above, and has a closed cell type of 3 to 30. The center seal member 4 is provided so as to be compressed and sandwiched in the radial direction of the casing 2 and the drive fan motor 3 so that axial vibration that tends to increase when the blower is driven The degree of transmission to the casing 2 through the seal member 4 can be reduced, and the vibration and noise of the blower resulting from the vibration of the casing 2 can be effectively reduced at low cost.

FIG. 3 is a schematic cross-sectional view of the blower of the washing / drying machine according to the second embodiment of the present invention.

第１の実施の形態の送風機と共通の部分については、同一符号を付して説明を省略する。   Portions common to the blower of the first embodiment are given the same reference numerals and description thereof is omitted.

ケーシング２と駆動用ファンモータ３の半径方向において、圧縮代（図示せず）を持って挟持される中央シール部材１４が設けてある。   In the radial direction of the casing 2 and the drive fan motor 3, a central seal member 14 is provided that is sandwiched with a compression allowance (not shown).

中央シール部材１４は、ＥＰＤＭなどのゴム材を主成分とし、独立気泡型に３〜３０倍に発泡させたシール性と柔軟性を備えた材料となっている。そして、ケーシング２の内周部には、軸方向に段差部１５を設け、その段差部１５に、中央シール部材１４の外周部位の一部が、ケーシング２の軸方向でも接触するように構成してある。   The central seal member 14 is made of a rubber material such as EPDM as a main component, and is a material having a sealing property and flexibility that is foamed 3 to 30 times in a closed cell type. Then, a step portion 15 is provided in the axial direction on the inner peripheral portion of the casing 2, and a part of the outer peripheral portion of the central seal member 14 is in contact with the step portion 15 also in the axial direction of the casing 2. It is.

以上の構成によって、シール部材１４の設置の際の、上下方向のずれを抑えることが可能となり、正しく装着することができ、それにより、低コストで送風機の振動、騒音を低減することができる。なお、段差部１５は実施の形態１において用いても効果がえられる。   With the above configuration, it is possible to suppress vertical displacement when the seal member 14 is installed, and the seal member 14 can be correctly mounted, thereby reducing vibration and noise of the blower at low cost. Note that the step 15 is effective even when used in the first embodiment.

なお、本実施の形態では洗濯乾燥機について示したが、振動が問題となる、洗濯機能の無い乾燥機であってもよい。   In the present embodiment, a washing / drying machine has been described. However, a washing machine without a washing function in which vibration is a problem may be used.

以上のように、本発明にかかる洗濯乾燥機は、中央シール部材により低コストで防振、防音性能を向上させることが可能となるので、送風手段を有する他の機器、例えば乾燥装置などの用途に適用できる。   As described above, the washing / drying machine according to the present invention can improve the vibration proofing and soundproofing performance at a low cost by the central seal member, so that it can be used for other equipment having a blowing means, such as a drying device.
