以下，本発明の実施例について図面を用いて詳細に説明する。 Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

図１は洗濯機乾燥１００の外観斜視図，図２は洗濯機乾燥１００の右側面断面図である。図１より，洗濯機１００は外郭を構成する筺体１を備え，筺体１の上部にトップカバー２を設けてあり，筐体１の下部にベース３が設けられている。ベース３には４つの脚が設けられているが，その内洗濯機本体に向かって右前の１箇所に高さが可能な調整脚３ａが設けられており，残りの３箇所は高さの調整ができない固定脚３ｂが設けられている。洗濯機を設置する際には，この調整脚３ａの高さを調整することで，本体の傾きやガタつきを調整する。また，トップカバー２には衣類投入口２ａを覆うように外蓋２ｂが設けられている。トップカバー２の前側には，電源スイッチ４や操作スイッチ５，表示器６を備えた操作パネル７が設けられている。なお，操作パネル７は，筺体１の背面に設けた制御装置１４に電気的に接続している。 FIG. 1 is an external perspective view of the washing machine drying 100, and FIG. 2 is a right side sectional view of the washing machine drying 100. From FIG. 1, the washing machine 100 includes a housing 1 constituting an outer shell, a top cover 2 is provided on the upper part of the housing 1, and a base 3 is provided on the lower part of the housing 1. The base 3 is provided with four legs, of which one on the right front side facing the washing machine body is provided with adjustable legs 3a, and the remaining three are for height adjustment. A fixed leg 3b that cannot be used is provided. When installing the washing machine, the inclination and rattling of the main body are adjusted by adjusting the height of the adjusting legs 3a. Further, the top cover 2 is provided with an outer lid 2b so as to cover the clothing inlet 2a. An operation panel 7 including a power switch 4, an operation switch 5, and a display 6 is provided on the front side of the top cover 2. The operation panel 7 is electrically connected to the control device 14 provided on the back surface of the housing 1.

筺体１の内部には，水を溜める外槽１０が四隅を吊り棒を介して筐体１に弾性支持されている。外槽１０の背面には，エアトラップ２１ａが設けてあり，その内部の圧力がチューブ２１ｂを介して水位センサ２１に伝えられ，外槽１０内に溜められた水の水位を検知する。筐体１の前方の隅には，安全スイッチ３１が設けられており，脱水時に外槽１０が振動した際に，所定の振動変位以上となった際に検知する構造となっている。 Inside the housing 1, outer tanks 10 for storing water are elastically supported by the housing 1 at four corners via hanging rods. An air trap 21a is provided on the back surface of the outer tank 10, and the pressure inside the air trap 21a is transmitted to the water level sensor 21 via the tube 21b to detect the water level of the water stored in the outer tank 10. A safety switch 31 is provided in the front corner of the housing 1, and has a structure that detects when the outer tank 10 vibrates during dehydration and exceeds a predetermined vibration displacement.

外槽１０の内部には，衣類を収納するための内槽８を備える。内槽８は，その外周壁に通水および通風のための多数の小さな貫通孔８ａと，その底壁に通水および通風のための複数の貫通孔８ｂを有し，その上縁部に流体バランサ９を備え，底部の内側には回転翼１１を回転自在に支持している。 Inside the outer tank 10, an inner tank 8 for storing clothes is provided. The inner tank 8 has a large number of small through holes 8a for water passage and ventilation on the outer peripheral wall thereof, and a plurality of through holes 8b for water passage and ventilation on the bottom wall thereof, and a fluid is provided at the upper edge thereof. A balancer 9 is provided, and a rotary blade 11 is rotatably supported inside the bottom portion.

外槽１０の底部の外側にはモータ１３が設けてあり，クラッチ機構１２を制御することで，内槽８と回転翼１１の回転を次のように動作させることが出来る。１つは，内槽８を静止させるように係止，または自由に回転できるように解放した状態で回転翼１１を繰り返し正逆回転させる動作で，主に衣類を撹拌させる場合に用いる。もう１つは，内槽８と回転翼１１を一体として同一方向に回転させる動作で，主に脱水する場合に用いる。 A motor 13 is provided on the outside of the bottom of the outer tank 10, and by controlling the clutch mechanism 12, the rotation of the inner tank 8 and the rotary blade 11 can be operated as follows. One is an operation in which the rotary blade 11 is repeatedly rotated in the forward and reverse directions in a state where the inner tank 8 is locked so as to be stationary or released so that it can be freely rotated, and is mainly used when the clothes are agitated. The other is an operation in which the inner tank 8 and the rotary blade 11 are integrally rotated in the same direction, and is mainly used for dehydration.

外槽１０の上面には槽カバー２３が設けてあり，槽カバー２３は上面と下面を連通する衣類投入口２３ａ，温風吹き出し口２３ｂ，給水入口２５ａを備える。また，槽カバー２３には，衣類投入口２３ａを覆うように内蓋２４が設けてあり，ヒンジ２４ａにより開閉自在とする。内蓋２４は，取っ手２４ｂを上方に持ち上げることでロックが解除されて開き，下方に押すことでロックされる。 A tank cover 23 is provided on the upper surface of the outer tank 10, and the tank cover 23 includes a clothing inlet 23a, a warm air outlet 23b, and a water supply inlet 25a that communicate the upper surface and the lower surface. Further, the tank cover 23 is provided with an inner lid 24 so as to cover the clothing inlet 23a, and can be opened and closed by the hinge 24a. The inner lid 24 is unlocked and opened by lifting the handle 24b upward, and locked by pushing it downward.

外槽１０の後側には乾燥ダクト１０ｃを設けている。乾燥ダクト１０ｃは蛇腹１０ｄを介して，乾燥ユニット１９に接続している。乾燥ユニット１９は，送風ファン１９ａの熱源であるヒータ１９ｂと，温度センサ１９ｃを備える。乾燥ユニット１９は，蛇腹２３ｃを介して，槽カバー２３に設けられた温風吹き出し口２３ｂに接続される。ヒータ１９ｂで温度を上昇させた空気を，送風ファン１９ａより循環することで衣類の乾燥を行う。また，筺体１には給水口２ｃに接続した給水電磁弁２５が設けてあり，内槽８や乾燥ダクト１０ｃに給水可能となっている。外槽１０の下部には排水するための排水口１０ｂを備えており，排水弁１５を介して排水ホース２４が接続している。 A drying duct 10c is provided on the rear side of the outer tank 10. The drying duct 10c is connected to the drying unit 19 via a bellows 10d. The drying unit 19 includes a heater 19b, which is a heat source for the blower fan 19a, and a temperature sensor 19c. The drying unit 19 is connected to the warm air outlet 23b provided on the tank cover 23 via the bellows 23c. The air whose temperature has been raised by the heater 19b is circulated from the blower fan 19a to dry the clothes. Further, the housing 1 is provided with a water supply solenoid valve 25 connected to the water supply port 2c so that water can be supplied to the inner tank 8 and the drying duct 10c. A drain port 10b for draining water is provided in the lower part of the outer tank 10, and a drain hose 24 is connected via a drain valve 15.

内槽８の上部に設ける流体バランサ９は，合成樹脂等でリング状に形成され，内部にいくつかの流路を有している。この流路には液体が封入されており，脱水時に振動が発生した際に，振動を低減する効果がある。具体的には，脱水時に衣類の片寄り（以下，アンバランス）により振動が生じた場合，共振回転数より高い回転数では，アンバランスの方向に対して位相が１８０度ずれた方向に振動する。この時，流体バランサ９内の液体は振動した方向に片寄ることになる。すなわち，アンバランスに対して，１８０度ずれた位置に片寄るため，アンバランスを相殺することができ，振動を低減することができる。 The fluid balancer 9 provided in the upper part of the inner tank 8 is formed of a synthetic resin or the like in a ring shape, and has some flow paths inside. A liquid is sealed in this flow path, which has the effect of reducing vibration when vibration occurs during dehydration. Specifically, when vibration occurs due to the offset of clothing (hereinafter referred to as unbalance) during dehydration, the vibration occurs in a direction that is 180 degrees out of phase with respect to the unbalanced direction at a rotation speed higher than the resonance rotation speed. .. At this time, the liquid in the fluid balancer 9 is biased in the vibrating direction. That is, since the position is offset by 180 degrees with respect to the imbalance, the imbalance can be offset and the vibration can be reduced.

図３は、槽カバー２３と内蓋２４を裏側（下方）から見た斜視図である。槽カバー２３の裏側には、衣類噛み込みを抑制するための、凸形状を有する凸部５０ａ及び５０ｂが設けられている。凸部５０ａは槽カバー２３の前側に設けられており、凸部５０ｂは槽カバー２３の後側に設けられている。 FIG. 3 is a perspective view of the tank cover 23 and the inner lid 24 as viewed from the back side (lower side). On the back side of the tank cover 23, convex portions 50a and 50b having a convex shape are provided to suppress the biting of clothes. The convex portion 50a is provided on the front side of the tank cover 23, and the convex portion 50b is provided on the rear side of the tank cover 23.

図４は、槽カバー２３と内蓋２４を表側（上方）から見た図であり、図５は、洗濯機乾燥１００の図４におけるＡＡ´断面図である。図５のＸで囲まれた領域（洗濯乾燥機の前方側）の拡大図が図６であり、図５のＹで囲まれた領域（洗濯乾燥機の後方側）の拡大図が図７ある。 FIG. 4 is a view of the tub cover 23 and the inner lid 24 as viewed from the front side (upper side), and FIG. 5 is a sectional view taken along line AA'in FIG. 4 of the washing machine drying 100. 6 is an enlarged view of the area surrounded by X in FIG. 5 (front side of the washer / dryer), and FIG. 7 is an enlarged view of the area surrounded by Y in FIG. 5 (rear side of the washer / dryer). ..

図６に示すように、槽カバー２３の裏側には、流体バランサ９よりも中心側に凸形状を有する凸部５０ａが設けられているため、衣類が流体バランサ９と槽カバー２３の間に挟まって傷むことを低減出来る。脱水中等において、凸部５０ａにより、図６の矢印の方向に示すように、衣類は流体バランサ９の傾斜面９ｂに当てて、内槽８内に引き込むことが出来る。そのため、凸部５０ａの内周側にも傾斜面を備えることが望ましい。 As shown in FIG. 6, since the convex portion 50a having a convex shape on the central side of the fluid balancer 9 is provided on the back side of the tank cover 23, clothing is sandwiched between the fluid balancer 9 and the tank cover 23. It can reduce the damage caused by During dehydration or the like, the convex portion 50a allows the clothing to hit the inclined surface 9b of the fluid balancer 9 and be drawn into the inner tank 8 as shown in the direction of the arrow in FIG. Therefore, it is desirable to provide an inclined surface on the inner peripheral side of the convex portion 50a.

また、流体バランサ９と凸部５０ａの間に隙間Ｓを設けている。これにより、脱水時等の外槽１０が傾くことによる、流体バランサ９と凸部５０ａの干渉を抑制している。 Further, a gap S is provided between the fluid balancer 9 and the convex portion 50a. As a result, interference between the fluid balancer 9 and the convex portion 50a due to the inclination of the outer tank 10 during dehydration or the like is suppressed.

また、凸部５０ａは流体バランサ９の上底９ａよりも下に延びていることで、効果的に衣類噛み込みを抑制できる。ただし、容量確保の関係上、凸部５０ａは流体バランサ９の底部よりも上にあることが望ましい。また、凸部５０ａを、流体バランサ９の傾斜面９ｂよりやや上方に設けることで、効果的に衣類を流体バランサ９の傾斜面９ｂに当てて、内槽８内に引き込むことが出来る。 Further, since the convex portion 50a extends below the upper bottom 9a of the fluid balancer 9, it is possible to effectively suppress the biting of clothing. However, in order to secure the capacity, it is desirable that the convex portion 50a is above the bottom portion of the fluid balancer 9. Further, by providing the convex portion 50a slightly above the inclined surface 9b of the fluid balancer 9, clothing can be effectively applied to the inclined surface 9b of the fluid balancer 9 and drawn into the inner tank 8.

図７を用いて説明する。洗濯乾燥機の後方側の槽カバー２３の裏側には凸部５０ｂに設けられている。図６と大きく異なる点は、凸部５０ｂの、内槽８の回転軸に対する周方向の長さＬ２は凸部５０ａのそれとりも長い。つまり、図３に示す通り、槽カバー２３の後側の方が前方側に比べて凸部５０の領域が大きい。これは、槽カバー２３の出来るだけ多くの領域に凸部５０を設けた方が衣類噛み込みの抑制の効果を期待でき、槽カバー２３の後側の面積の方が乾燥ユニット１９等の配置の関係で大きいからである。 This will be described with reference to FIG. A convex portion 50b is provided on the back side of the tub cover 23 on the rear side of the washer / dryer. The major difference from FIG. 6 is that the length L2 of the convex portion 50b in the circumferential direction with respect to the rotation axis of the inner tank 8 is longer than that of the convex portion 50a. That is, as shown in FIG. 3, the region of the convex portion 50 is larger on the rear side of the tank cover 23 than on the front side. This is because it is expected that the convex portion 50 is provided in as many areas as possible of the tank cover 23 to suppress the biting of clothes, and the area on the rear side of the tank cover 23 is the arrangement of the drying unit 19 and the like. This is because the relationship is large.

その他の構成等は図６と同様であるため説明を省略する。 Since other configurations and the like are the same as those in FIG. 6, the description thereof will be omitted.

以上本実施例によれば、槽カバー２３の裏側に、流体バランサ９よりも中心側に凸形状を有する凸部５０が設けることで、コストアップを抑制しつつ衣類の噛み込みを抑制可能な洗濯機乾燥機を提供できる。 As described above, according to the present embodiment, by providing the convex portion 50 having a convex shape on the central side of the fluid balancer 9 on the back side of the tank cover 23, it is possible to suppress the biting of clothes while suppressing the cost increase. A machine dryer can be provided.
