Description

本発明は、洗濯物の脱水時に効果的に湿気を除去するようにしたドラム式洗濯機に関する。   The present invention relates to a drum-type washing machine that effectively removes moisture when dewatering laundry.

近年、洗濯機は、従来よりの縦軸型の円筒状水槽および回転槽による筐体上面の開口から洗濯物を投入する構成から、図4に概略構成を示すように、回転槽を横軸型のドラム(66)とし、開口を筐体の前面側に設けて洗濯物の投入口(57)とした、いわゆるドラム式洗濯機(51)が商品化され普及しつつある。この種ドラム式洗濯機における洗濯水槽(60)は円筒状をなし、外郭を形成する筐体(52)の内部に、水平に対して前方が高くなるように支持装置(61)を介して弾性的に支持されており、この水槽(60)の内部には、間隙を形成してドラム(66)を回転可能に設け、ドラム(66)は水槽(60)の後面に取り付けられたモーター(67)により回転駆動される。   2. Description of the Related Art In recent years, a washing machine has a horizontal axis type rotary tank as shown in FIG. The so-called drum-type washing machine (51), which has a drum (66) and an opening provided on the front side of the housing and serves as a laundry inlet (57), has been commercialized and is becoming popular. The washing tub (60) in this kind of drum-type washing machine has a cylindrical shape, and is elasticated via a support device (61) inside the housing (52) forming the outer shell so that the front is higher than the horizontal. A drum (66) is rotatably provided in the water tank (60) with a gap formed therein, and the drum (66) is a motor (67) attached to the rear surface of the water tank (60). ).

前記筐体(52)の前面側に設けた洗濯物を出し入れするための投入口(57)には、投入口(57)を開閉するドア(58)が配設されており、洗濯、脱水、乾燥時にはドア(58)をロックすることにより、水槽(60)内の洗濯用水が隙間などから外部にあふれ出ないよう密閉構造となるように形成している。   A door (58) for opening and closing the loading port (57) is disposed at the loading port (57) for loading and unloading the laundry provided on the front side of the housing (52). By locking the door (58) during drying, it is formed in a sealed structure so that the washing water in the water tub (60) does not overflow from the gap or the like.

上記により、ドラム式洗濯機における水槽(60)は密閉された構造であることから、洗濯物の乾燥時には、前記水槽(60)の上方に配置した乾燥ヒーター(69)およびファン(70)からなる乾燥ユニット(68)で生成される加熱空気を前記ドラム(66)内に導入し、衣類などを乾燥する方式であったが、前記乾燥ヒーター(69)とファン(70)からなる乾燥ユニット(68)はコスト的に高く、乾燥機能を有する洗濯乾燥機を保有していても洗濯機能を主体に使用している家庭においては、過剰仕様の商品となっていた。   As described above, since the water tub (60) in the drum-type washing machine has a hermetically sealed structure, when the laundry is dried, the drying tub (60) and the fan (70) are arranged above the water tub (60). The heating air generated by the drying unit (68) is introduced into the drum (66) to dry clothes and the like. The drying unit (68) comprising the drying heater (69) and the fan (70) is used. ) Is high in cost, and even if it has a washing and drying machine having a drying function, it has become an over-designed product in homes that mainly use the washing function.

これに対して、図5に示すように、ドラム式洗濯機におけるドラム(86)の回転軸部(87)に一体に翼体(88)を設け、この翼体(88)の回転によって外気を吸気風路(89)からドラム(86)内に吸い込み、洗濯物を外気と接触させることで水分の蒸発を促進させる構成が特許文献1に記載されている。
特開2005−261691号公報
On the other hand, as shown in FIG. 5, a wing body (88) is provided integrally with the rotating shaft portion (87) of the drum (86) in the drum type washing machine, and outside air is removed by the rotation of the wing body (88). Patent Document 1 describes a configuration in which evaporation of moisture is promoted by sucking air from an intake air passage (89) into a drum (86) and bringing the laundry into contact with outside air.
Japanese Patent Laid-Open No. 2005-261691

しかしながら、前記特許文献1に示されている構成では、ドラム(86)の回転によって、衣類などの洗濯物が側壁部の中央に位置する翼体(88)に絡まる恐れがある。また、吸気風路(89)がドラム(86)の回転軸(87)部にあることから、洗濯時におけるドラム(86)内の水位によっては、洗濯水が吸気風路(89)から外方へ逆流する可能性がある。そして、これを防ぐためには、溢水しない防水構造を採用する必要を生じ、却ってコスト高となる問題があった。   However, in the configuration shown in Patent Document 1, there is a possibility that laundry such as clothes may get entangled with the wing body (88) located at the center of the side wall portion by the rotation of the drum (86). In addition, since the intake air passage (89) is located on the rotating shaft (87) of the drum (86), the wash water may flow outward from the intake air passage (89) depending on the water level in the drum (86) during washing. There is a possibility of backflow. In order to prevent this, it is necessary to adopt a waterproof structure that does not overflow, and there is a problem that the cost is increased.

本発明は上記点を考慮してなされたものであり、乾燥ユニットを使用せずとも洗濯物を乾かすことができるとともに、翼体構成によることなく衣類の絡まりや溢水、さらには防水機構の必要をなくしてコストを低くすることができるドラム式洗濯機を提供することを目的とする。   The present invention has been made in consideration of the above points, and it is possible to dry laundry without using a drying unit, and there is a need for a tangled or overflowing clothing, and a waterproof mechanism without depending on the wing structure. An object of the present invention is to provide a drum-type washing machine that can be reduced in cost.

上記課題を解決するために、本発明におけるドラム式洗濯機は、外郭を形成する筐体の内部に弾性支持した水槽と、この水槽の内部に横軸周りに回転可能に配設したドラムと、前記水槽およびドラムの前方に対向して前記筐体の前面に設けた投入口と、この投入口を開閉すべく回動可能に設けたドアとを備えたものにおいて、前記水槽における洗濯時の水位高さより上部位置に外気を吸引する吸気口を設け、この吸気口からドラムの内部に吸引され排出される外気の排気口を前記水位高さより上方に形成したことを特徴とするものである。   In order to solve the above problems, a drum-type washing machine according to the present invention includes a water tank elastically supported inside a casing that forms an outer shell, and a drum that is rotatably disposed around the horizontal axis inside the water tank. A water level at the time of washing in the water tub, comprising a charging port provided in front of the casing facing the front of the water tank and the drum, and a door rotatably provided to open and close the charging port. An intake port for sucking outside air is provided at a position above the height, and an exhaust port for outside air that is sucked into the drum from the intake port and discharged is formed above the water level.

本発明のドラム式洗濯機によれば、洗濯物から効果的に湿気を除去することができるとともに、絡まりにより洗濯物を痛めたり、溢水防止のための複雑な構成を採用することなく、安価な乾燥構成を得ることができる。   According to the drum type washing machine of the present invention, moisture can be effectively removed from the laundry, and it is inexpensive without damaging the laundry due to entanglement or employing a complicated configuration for preventing overflow. A dry configuration can be obtained.

以下図面に基づき本発明の1実施形態について説明する。図1に概略斜視図、図2に側断面図を示すドラム式洗濯機(1)は、外郭を形成する筐体(2)をコ字状に曲げ成形して背部と両側部を形成した外側板(3)とこの前面および背部の点検口を閉塞する前面板(4)と背面板(5)とから構成している。   An embodiment of the present invention will be described below with reference to the drawings. The drum-type washing machine (1) having a schematic perspective view in FIG. 1 and a side sectional view in FIG. 2 is an outer side in which a casing (2) forming an outer shell is bent into a U-shape to form a back portion and both side portions. It consists of a plate (3), a front plate (4) and a back plate (5) for closing the front and back inspection ports.

そして、前面板(4)の上部には、洗濯コースなどを選択設定するための操作パネル(6)を配置するとともに、中央部分には洗濯物を出し入れするための円形の投入口(7)を開口させ、前記投入口(7)の周囲は、例えば、円形状に凹陥部を形成することで、投入口(7)を閉塞するドア(8)をその前面が前記前面板(4)とほぼ同一面になるように配置している。   An operation panel (6) for selecting and setting a washing course and the like is disposed on the upper portion of the front plate (4), and a circular insertion opening (7) for taking in and out the laundry is provided in the center portion. The opening (7) is opened and the periphery of the inlet (7) is formed, for example, in a circular recess, so that the door (8) that closes the inlet (7) has a front surface substantially the same as the front plate (4). They are arranged on the same plane.

すなわち、ドア(8)は、前記前面板(4)の凹陥部形状に合わせて円形状をなすとともに前記投入口(7)に対応する前面部を透明体で形成し、周縁枠を介してドア内板(9)を形成してなり、ドア内板(9)は、前記前面部の透明部分と併せて内部を透視できるように、洗剤などの耐薬品性に優れた透明樹脂、あるいはガラスで形成した円形窓を前記円形の投入口(7)形状に合わせて内方向に膨出させるとともに、一側をヒンジ部材で枢支して横方向に開閉可能に取り付けている。   That is, the door (8) has a circular shape corresponding to the shape of the recessed portion of the front plate (4), and a front portion corresponding to the insertion port (7) is formed of a transparent body, and the door is inserted through the peripheral frame. An inner plate (9) is formed, and the door inner plate (9) is made of a transparent resin excellent in chemical resistance such as detergent or glass so that the inside can be seen through together with the transparent portion of the front portion. The formed circular window is swelled inward according to the shape of the circular inlet (7), and one side is pivotally supported by a hinge member so as to be opened and closed in the lateral direction.

筐体(2)の内部には水槽(10)が配置されている。筐体を省略した斜視図である図3からより理解されるように、水槽(10)は、横軸型の円筒状をなして背面を閉塞し、その前面部の開口周縁には環状の水槽カバー(10a)を取り付けるとともに、その底部の左右に設けた一対の支持装置(11)によって筐体(2)内に弾性的に支持されており、背面側の下方には排水弁(12)を介して機外に導出する排水ホース(13)を接続している。   A water tank (10) is disposed inside the housing (2). As can be understood from FIG. 3 which is a perspective view in which the housing is omitted, the water tank (10) has a horizontal axis cylindrical shape and closes the back surface. A cover (10a) is attached and elastically supported in the housing (2) by a pair of support devices (11) provided on the left and right sides of the bottom, and a drain valve (12) is provided below the back side. A drain hose (13) leading out of the machine is connected.

本体上部の一側には、給水弁に接続した給水口(14)を設けており、洗濯水としての水道水を供給し、貯留するように構成している。また、給水口(14)に隣接する本体前部には、洗剤投入口(15)が設置されており、洗濯時には給水とともに所定量の洗剤が水槽(10)内に供給されるようにしている。   A water supply port (14) connected to a water supply valve is provided on one side of the upper part of the main body, and is configured to supply and store tap water as washing water. In addition, a detergent inlet (15) is installed at the front of the main body adjacent to the water supply port (14) so that a predetermined amount of detergent is supplied into the water tank (10) together with water supply during washing. .

水槽(10)の内部には、横軸周りに回転可能としたステンレス製で有底円筒状のドラム(16)を配設している。ドラム(16)は、水槽(10)に沿い前方に向かって若干上方への傾斜状態に支承されており、胴部周壁に多数の脱水孔(16a)と、その内周面には洗濯物掻き上げ用のバッフル(16b)を複数有している。また前面開口側には環状のドラムカバー(16c)を取り付けて、前記水槽カバー(10a)とともに投入口(7)に対向して配置させており、洗い運転および脱水運転における共用槽として機能するものである。   Inside the water tank (10), a cylindrical drum (16) with a bottom made of stainless steel that can rotate around the horizontal axis is disposed. The drum (16) is supported in an inclined state slightly upward toward the front along the water tank (10), and a number of dewatering holes (16a) are formed in the peripheral wall of the trunk portion, and the laundry is scraped on the inner peripheral surface thereof. A plurality of raising baffles (16b) are provided. In addition, an annular drum cover (16c) is attached to the front opening side, and is disposed opposite to the charging port (7) together with the water tank cover (10a), and functions as a common tank in the washing operation and dehydration operation. It is.

前記ドラム(16)の閉塞された背面は、水槽(10)の前記閉塞された背面部に軸支され、洗いおよび脱水運転に応じた回転速度に制御されるモータ(17)により回転する。このモータ(17)は、例えば、アウターロータ形であって、内側のステータ(17c)を水槽(10)側に固定し、外側のロータ(17a)に直結した回転軸(17b)を水槽(10)の後壁を水密に貫通させるとともにドラム(16)背面部の中心に連結させている。   The closed back surface of the drum (16) is pivotally supported by the closed back surface portion of the water tank (10), and is rotated by a motor (17) controlled at a rotation speed corresponding to a washing and dehydrating operation. The motor (17) is, for example, an outer rotor type, and an inner stator (17c) is fixed to the water tank (10) side, and a rotating shaft (17b) directly connected to the outer rotor (17a) is connected to a water tank (10 ) The rear wall of the drum (16) is connected to the center of the back surface of the drum (16).

前記前面板(4)における投入口(7)の開口周縁と水槽(10)の前面開口部における水槽カバー(10a)との間隙には、耐薬品性に優れた軟質樹脂材からなるベローズ(18)を取り付け、水が水槽(10)から機外に漏れ出ないようにするとともに、その一部を延出して閉鎖状態にある前記ドア(8)裏面側の透明窓(9)に当接させ、投入口(7)から機外への水漏れも防止し、さらに蛇腹部を設けて水槽(10)やドラム(16)の回転振動がドア(8)側に伝達することを防いでいる。   A bellows (18) made of a soft resin material having excellent chemical resistance is provided in the gap between the opening periphery of the inlet (7) in the front plate (4) and the water tank cover (10a) in the front opening of the water tank (10). ) To prevent water from leaking out of the machine from the water tank (10), and a part of the water is extended and brought into contact with the transparent window (9) on the back side of the door (8) in the closed state. Further, water leakage from the charging port (7) to the outside of the machine is prevented, and a bellows portion is provided to prevent the rotational vibration of the water tank (10) and the drum (16) from being transmitted to the door (8) side.

しかして、前記洗剤投入口(15)に対応する前面板(4)の投入口(7)の他方側の上方位置には、断面が幅方向に長い長孔形状をなして上面が水槽(10)の外方に開口し、下方は水槽カバー(10a)内におけるドラム(16)の前面開口部に対応して開口する筒状の吸気口(19)を設けており、この吸気口(19)の開口部には、フィルター部材(20)がネジによって着脱自在に取り付けられている。   Thus, at the upper position on the other side of the loading port (7) of the front plate (4) corresponding to the detergent loading port (15), the upper surface is a water tank (10 ), And the lower part is provided with a cylindrical air inlet (19) corresponding to the front opening of the drum (16) in the water tank cover (10a). The air inlet (19) A filter member (20) is detachably attached to the opening of the first and second openings by screws.

そして、前記吸気口(19)に対応する筐体(2)の天井部には、化粧格子を設けた開口(2a)を形成しており、また、前記吸気口(19)に対して後方に位置する水槽(10)の上部には、下方がドラム(16)と水槽(10)との間に開口し、上方が水槽(10)の上面に開口する排気口(21)を設けている。   An opening (2a) provided with a decorative lattice is formed in the ceiling portion of the housing (2) corresponding to the air inlet (19), and rearward with respect to the air inlet (19). The upper part of the water tank (10) is provided with an exhaust port (21) whose lower part opens between the drum (16) and the water tank (10) and whose upper part opens on the upper surface of the water tank (10).

この排気口(21)の上端縁には、軟質ゴムなどの弾性体で形成された排気ダクト(22)が嵌合されており、排気ダクト(22)は後方に屈曲し、外側板(3)を貫通して外気中に開口させている。この排気ダクト(22)の開口部には、これを覆って内部からの排気を外部上方に向かわせるように半円筒状の排気カバー(23)を外箱(3)面に配設しており、槽(16)(10)内からの排気を洗濯機本体(1)の背面上方に導き外気中に拡散させるようにしている。   An exhaust duct (22) formed of an elastic body such as soft rubber is fitted to the upper end edge of the exhaust port (21), and the exhaust duct (22) is bent rearward to form the outer plate (3). Is opened to the outside air. The exhaust duct (22) has a semi-cylindrical exhaust cover (23) on the surface of the outer box (3) so as to cover the exhaust duct (22) and to direct exhaust from the inside upward. The exhaust from the tanks (16) and (10) is guided to the upper back of the washing machine body (1) and diffused into the outside air.

上記構成のドラム式洗濯機(1)は、「洗い」「すすぎ」「脱水」の各機能行程を選択設定して自動的に実行するものであり、前記投入口(7)より洗濯物をドラム(16)内に投入した後、「洗い」および「すすぎ」行程では、洗濯水を水槽(10)内に供給した状態でドラム(16)を低速回転させ、洗濯物をバッフル(16b)で掻き上げては落下させる撹拌運動により洗濯を実行し、「脱水」行程ではドラム(16)を一方向に高速回転させて脱水する。   The drum-type washing machine (1) having the above-mentioned configuration automatically selects and executes the function steps of “washing”, “rinsing”, and “dehydration”, and the laundry is drummed from the charging port (7). (16) In the “washing” and “rinsing” processes after being put in, the drum (16) is rotated at a low speed while washing water is supplied into the water tank (10), and the laundry is scraped with the baffle (16b). Washing is carried out by a stirring motion that drops and drops, and in the “dehydration” process, the drum (16) is rotated at high speed in one direction to dehydrate.

したがって、「脱水」行程では、洗濯後の洗濯物の水分が、前記ドラム(16)の胴部周壁に穿設した多数の脱水孔(16a)から遠心力で振り切られることで脱水がおこなわれるが、このとき同時に、ドラム(16)内の空気も脱水孔(16a)から排出されるものであり、ドラム(16)内が負圧になることから、前記水槽(10)上部の吸気孔(19)には、対応する筐体(2)天井面に形成した開口(2a)を介して大量の乾燥した外気が吸引され、投入口(7)の後部近傍からドラム(16)の前面開口に流入する。このとき、吸気口(19)には、前記フィルター部材(20)が設けられていることから、外気中の埃や虫などがドラム(16)内に侵入して洗濯物に付着することを防止できる。   Therefore, in the “dehydration” process, the moisture of the laundry after washing is dewatered by being spun off by a centrifugal force from a number of dewatering holes (16a) drilled in the peripheral wall of the drum (16). At the same time, the air in the drum (16) is also discharged from the dewatering hole (16a), and the inside of the drum (16) becomes negative pressure. ), A large amount of dry outside air is sucked into the corresponding housing (2) through the opening (2a) formed in the ceiling surface, and flows into the front opening of the drum (16) from the vicinity of the rear of the charging port (7). To do. At this time, since the filter member (20) is provided in the intake port (19), dust and insects in the outside air can be prevented from entering the drum (16) and adhering to the laundry. it can.

そして、ドラム(16)の内部で、洗濯物に接触してその水分を奪い、湿気を含んだ空気として脱水孔(16a)から外方へ排出されるものであり、洗濯物は遠心力による脱水とともに、吸引された空気による除湿作用を強制的に受け、乾燥作用を大いに促進させることができる。   And inside the drum (16), it contacts the laundry and deprives it of moisture, and is exhausted outward from the dewatering hole (16a) as moisture-containing air. The laundry is dewatered by centrifugal force. At the same time, the dehumidifying action by the sucked air is forcibly received, and the drying action can be greatly promoted.

前記脱水孔(16a)から排出される空気は、ドラム(16)の外面と水槽(10)の内面間に流出して密閉された空間である水槽(10)上面に開口させた排気口(21)に導かれ、排気ダクト(22)内を通って外部に放出される。   The air discharged from the dewatering hole (16a) flows out between the outer surface of the drum (16) and the inner surface of the water tank (10) and is exhausted from the upper surface of the water tank (10) which is a sealed space (21 ) And discharged to the outside through the exhaust duct (22).

このとき、排気は外気中に放出させた方がよい。なぜならば、筐体(2)内に排出した場合は、筐体(2)内部に排気が充満する可能性もあり、その場合には、排気能力が低下して新しい乾燥空気の取り入れに支障を来すばかりでなく、湿気を含んだ空気により壁内面に露付きを生じる懸念があるが、外気中に放出することにより加湿空気の放散とともに滞留することがないので、充分な吸気量を確保することができる。   At this time, the exhaust is preferably discharged into the outside air. This is because if the air is discharged into the housing (2), there is a possibility that the exhaust inside the housing (2) will be filled. In that case, the exhaust capacity will be reduced, which will hinder the intake of new dry air. There is a concern that the inside of the wall will be exposed to moisture due to air containing moisture, but it will not stay with the emission of humidified air by releasing it into the outside air, so ensure a sufficient amount of intake air be able to.

上述の実施例における排気口(21)は、水槽(10)の上面における前記吸気口(19)からより遠い背面側に開口させているため、ドラム(10)の前方から進入した吸気は槽内の洗濯物と前後に亙って長く接触してから後部の排気口(21)から流出することになり、洗濯物の乾燥をより助長させることができる。そして、排気ダクト(22)から流出した空気は、外側板(3)の背面上部から排気カバー(23)によってさらに上方に導かれて外気中に放散するため、洗濯機本体(1)と室壁面間に滞留して露付き現象を生じることはなく、カビなどの発生を抑制することができる。   Since the exhaust port (21) in the above-described embodiment is opened on the back side farther from the intake port (19) on the upper surface of the water tank (10), the intake air that has entered from the front of the drum (10) It will flow out from the rear exhaust port (21) after a long contact with the laundry in the front and rear, and drying of the laundry can be further promoted. And since the air which flowed out from the exhaust duct (22) is guide | induced further upward by the exhaust cover (23) from the back upper part of an outer side board (3), it dissipates in outside air, Therefore A washing machine main body (1) and a room wall surface It does not cause a dew phenomenon due to staying in the middle, and the generation of mold and the like can be suppressed.

前記吸気口(19)および排気口(21)は、それぞれ水槽(10)の上部に配置させていることから、「洗い」や「すすぎ」の洗濯行程における攪拌される水位の影響を受けないものであり、槽外に水が溢れ出ることを防ぐことができる。なお、この吸気口(19)および排気口(21)を設置する箇所は洗濯時における水位より高い位置であればよく、水槽(10)の上部である必要はない。   The intake port (19) and the exhaust port (21) are arranged at the upper part of the water tank (10), respectively, so that they are not affected by the agitated water level in the washing process of "washing" or "rinsing". It is possible to prevent water from overflowing outside the tank. The place where the intake port (19) and the exhaust port (21) are installed need only be higher than the water level at the time of washing, and need not be above the water tank (10).

上記構成によれば、洗濯後の「脱水」行程により、ドラム(16)内の洗濯物は、ドラム(16)の回転による遠心力での脱水作用とともに、吸入された外気による除湿作用によって、従来のヒーターとファンからなる乾燥ユニット(68)を用いることなく、ほぼ乾燥状態にすることができるものであり、安価に乾燥効果を得ることができる。   According to the above configuration, the laundry in the drum (16) is conventionally dehydrated by centrifugal force due to the rotation of the drum (16) and dehumidified by the sucked outside air by the "dehydration" process after washing. Without using a drying unit (68) consisting of a heater and a fan, it can be brought into a substantially dry state, and a drying effect can be obtained at a low cost.

また構造的にも現状のドラム式洗濯機構成における水槽カバー(10a)や水槽(10)と一体に吸気口(19)および排気口(21)を形成することができ、前記排気口(21)、排気ダクト(22)および排気カバー(23)は、通常後方に向かって下方傾斜させた状態に配設するドラム(16)および水槽(10)の後部傾斜空間に設置することができるので、新たな設置スペースを設ける必要がなく、本体外郭形状も拡大したり変更せずともよいので、大きな仕様変更を伴うことなく効果的な乾燥機能を付加することができるものである。   Further, structurally, the air inlet (19) and the air outlet (21) can be formed integrally with the water tank cover (10a) and the water tank (10) in the current drum type washing machine configuration. The exhaust duct (22) and the exhaust cover (23) can be installed in the rear inclined space of the drum (16) and the water tank (10) that are normally inclined downward toward the rear. It is not necessary to provide a large installation space and the outer shape of the main body does not need to be enlarged or changed, so that an effective drying function can be added without a large specification change.

なお、成形体としての排気口(21)部材を特に設置せず、水槽(10)上部における他部品との隙間を排気口として活用してもよく、また、水槽(10)の下部に接続した前記排水弁(12)を開弁して排水ホース(13)から排気するようにしてもよい。   In addition, the exhaust port (21) member as a molded body is not particularly installed, and the gap between the upper part of the water tank (10) and other parts may be used as an exhaust port, and connected to the lower part of the water tank (10). The drain valve (12) may be opened to exhaust from the drain hose (13).

また、排気口(21)部分における開口面積は、少なくとも前記吸気口(19)の開口面積より大きく設定することにより、ドラム(16)内に吸入した外気が滞留することなく、充分な外気の吸入量を確保することができ、且つ、スムーズな吸入、循環、排気行程を形成することができる。   Further, by setting the opening area at the exhaust port (21) to be at least larger than the opening area of the intake port (19), the intake air can be sufficiently sucked without the outside air sucked into the drum (16). The amount can be secured, and a smooth suction, circulation, and exhaust stroke can be formed.

そしてまた、前記「洗い」や「脱水」運転中には、撹拌や脱水による水飛沫を生じるが、水槽(10)は本体外面(3)に対して水密に配設されており、また、投入口(7)の開口縁部に装着したベローズ(18)は、ドア(8)裏面側に膨出したガラス窓(9a)に弾性的に接触していることにより、飛沫水は確実にシールされ、本体(1)および水槽(10)外に水が漏れ出ることはない。   In addition, during the “washing” and “dehydration” operations, water droplets are generated by stirring and dehydration, but the water tank (10) is disposed in a watertight manner with respect to the outer surface (3) of the main body. The bellows (18) attached to the opening edge of the mouth (7) is in elastic contact with the glass window (9a) bulged on the back side of the door (8), so that splashed water is reliably sealed. The water does not leak out of the main body (1) and the water tank (10).
