Description

洗濯機Washing machine
　本発明は、衣類等の洗濯物を洗う洗濯機に関する。 The present invention relates to a washing machine for washing laundry such as clothes.
　一般的に、洗濯機には、衣類等の洗濯物を回転槽内で撹拌して洗う縦型洗濯機、および、洗濯物を回転槽内で回転槽の回転方向へ持ち上げて上方から落下させて叩き洗いするドラム式洗濯機がある。いずれの洗濯機も洗剤の化学力に加えて、洗濯物に機械力を作用させて洗うように構成される。また、洗った洗濯物を脱水する構成としては、回転槽の高速回転による遠心力により、洗濯物から水分を分離する遠心力脱水が一般的である。 In general, a washing machine has a vertical washing machine that agitates and wash laundry such as clothes in a rotating tub, and lifts laundry in a rotating tub in a rotating direction of the rotating tub and drops the laundry from above. There is a drum type washing machine that performs slap washing. Both washing machines are configured to apply mechanical force to the laundry in addition to the chemical force of the detergent to wash the laundry. In addition, as a configuration for dehydrating the washed laundry, centrifugal dehydration for separating water from the laundry by centrifugal force due to high-speed rotation of the rotating tub is common.
　洗濯物に機械力を作用させて洗うこれらの洗濯機は、以下のような洗濯物の洗濯には不向きである。すなわち、布傷みが生じ易い洗濯物、洗濯物が絡んで引っ張られることにより型崩れしやすい洗濯物、または風合いが劣化し易い洗濯物である。風合いが劣化し易い洗濯物としては、一般的に手洗いされる、例えば、セーター、カーディガン等の毛糸の編み物や毛織物、極細の繊維で作られたデリケートな素材のスカーフ等がある。また、洗濯後の脱水においても上述した洗濯物には遠心力脱水は不向きである。そこで、上述したような、一般的に手洗いされる洗濯物に対し、洗濯物に押圧力を作用させて、脱水を行う洗濯機が考えられている（例えば、特許文献１参照）。 機械 These washing machines, which use mechanical force to wash laundry, are not suitable for washing laundry as described below. That is, the laundry is a laundry that easily suffers from cloth damage, a laundry that easily loses its shape due to the laundry being entangled and pulled, or a laundry that tends to deteriorate in texture. The laundry whose texture is likely to be deteriorated is generally hand-washed, for example, knitted wool or woolen fabric such as a sweater and a cardigan, and a scarf of a delicate material made of ultrafine fibers. Also, centrifugal dehydration is not suitable for the above-mentioned laundry in the dehydration after washing. In view of the above, there has been proposed a washing machine that performs dehydration by applying a pressing force to laundry that is generally washed by hand as described above (for example, see Patent Literature 1).
　特許文献１に記載された脱水装置は、図９に示されるように、洗濯槽５１の下方空間５２を減圧装置５３により減圧した後、圧力応動体５４の蛇腹形状の伸縮部５５の下端に設けられた押圧部５６を下動させる。これにより、押圧部５６によって、洗濯物を押圧して圧縮し、脱水が行われる。 As shown in FIG. 9, the dewatering device described in Patent Literature 1 is provided at the lower end of a bellows-shaped expansion / contraction portion 55 of a pressure responsive body 54 after a pressure in a lower space 52 of a washing tub 51 is reduced by a decompression device 53. The pressed portion 56 is moved downward. As a result, the laundry is pressed and compressed by the pressing portion 56, and dehydration is performed.
　ここで、洗濯槽５１の上面開口を開閉する蓋５７は、洗濯機外枠５８の上端に軸５９にて回動自在に枢支されている。そして、伸縮部５５の上端が蓋５７の内面に取り付けられている。このような構成により、最終の脱水工程（本発明の実施の形態において脱水ステップに相当する）後においては、圧力応動体５４の押圧部５６が上方位置に引き上げられ、伸縮部５５が折り畳まれた状態で全工程が終了する。 Here, the lid 57 for opening and closing the upper surface opening of the washing tub 51 is pivotally supported at the upper end of the outer frame 58 of the washing machine by a shaft 59 so as to be rotatable. Further, the upper end of the elastic portion 55 is attached to the inner surface of the lid 57. With such a configuration, after the final dehydration step (corresponding to the dehydration step in the embodiment of the present invention), the pressing portion 56 of the pressure responsive body 54 is pulled up to the upper position, and the elastic portion 55 is folded. All the steps are completed in this state.
　また、加圧体をベローズ等の可撓性を有する伸縮部材で構成し、その加圧体の往復運動させる洗濯機が考えられている（例えば、特許文献２参照）。この洗濯機は、加圧体によって洗濯物および洗濯液を繰り返し加圧して、押し洗いを行う構成である。 洗濯 Also, a washing machine in which the pressurizing member is formed of a flexible expandable member such as a bellows and the pressurizing member reciprocates has been considered (for example, see Patent Document 2). This washing machine is configured to repeatedly pressurize the laundry and the washing liquid by a pressurizing body to perform push washing.

　しかしながら、上記特許文献１に記載された従来の構成では、圧力応動体５４に設けられた押圧部５６を下動させて洗濯物を押圧圧縮して脱水するときに、洗濯物から脱水される水の殆どは、減圧装置５３により吸引されて機外に排水される。一方、蛇腹形状の伸縮部５５に付着した水は減圧装置５３によって吸引されず、すなわち排水されない。したがって、この水は、圧力応動体５４が上方位置に引き上げられたときに、折り畳まれた状態の伸縮部５５に付着したまま残る。 However, in the conventional configuration described in Patent Document 1, when the pressing portion 56 provided on the pressure responsive body 54 is moved downward to press and compress the laundry and dehydrate the laundry, the water dewatered from the laundry is removed. Is sucked by the pressure reducing device 53 and drained outside the machine. On the other hand, water adhering to the bellows-shaped expansion / contraction part 55 is not sucked by the pressure reducing device 53, that is, is not drained. Therefore, when the pressure responsive body 54 is pulled up to the upper position, the water remains attached to the expanded and contracted portion 55 in the folded state.
　特に、洗い工程（本発明の実施の形態において洗いステップに相当する）後の中間脱水工程（本発明の実施の形態において中間脱水動作に相当する）では、洗濯槽５１内の水に、洗濯物に付着していた汚れ、または洗剤成分などが多く含まれるため、長期の使用により伸縮部５５に汚れが堆積するおそれがある。さらに、不使用時は、伸縮部５５が折り畳まれているため、使用者は、伸縮部５５の汚れ等が拭き取り難く、清潔に保つことが困難となるおそれがある。 In particular, in the intermediate dehydration step (corresponding to the intermediate dehydration operation in the embodiment of the present invention) after the washing step (corresponding to the washing step in the embodiment of the present invention), the water in the washing tub 51 is added to the laundry. Since a large amount of dirt or detergent components is attached to the surface, there is a possibility that dirt may accumulate on the elastic portion 55 due to long-term use. Furthermore, when not in use, since the elastic part 55 is folded, it is difficult for the user to wipe off the dirt and the like of the elastic part 55, and it may be difficult to keep the user clean.
　本発明は、機械力を作用させて洗うことが不向きな被洗浄物の洗濯に、伸縮自在な押圧部によって被洗浄物に押圧力を作用させるものにおいて、押圧部を膜体で覆って押圧部への汚れの付着を防止する。さらに、押圧部の動きに膜体を追従させて被洗浄物に押圧力を作用させることができる洗濯機を提供することを目的とする。 The present invention is directed to a method of applying a pressing force to an object to be cleaned by a telescopically pressing portion when washing the object to be cleaned which is not suitable for washing by applying a mechanical force. To prevent dirt from adhering to the surface. It is still another object of the present invention to provide a washing machine capable of applying a pressing force to an object to be cleaned by causing a membrane to follow a movement of a pressing portion.
　本発明の洗濯機は、被洗浄物と洗浄水とを収容する洗浄槽と、洗浄槽の開口部を開閉する蓋体と、蓋体に設けられ、伸縮自在な押圧部と、前記押圧部を覆う膜体と、洗浄槽に収容された被洗浄物に対して押圧部を進退させる加圧減圧部と、加圧減圧部を制御する制御部とを備え、膜体は、可撓性を有する材料で構成され、膜体には押圧部の被洗浄物に対する進退に追従可能に変形する変形吸収部が設けられたものである。 The washing machine of the present invention includes a washing tub for storing an object to be washed and washing water, a lid that opens and closes an opening of the washing tub, a telescopic pressing portion provided on the lid, and the pressing portion. A covering body, a pressurizing and depressurizing unit that advances and retreats the pressing unit with respect to the object to be cleaned stored in the cleaning tank, and a control unit that controls the pressurizing and depressurizing unit, the film body has flexibility The film body is provided with a deformation absorbing portion that deforms so as to follow the advance and retreat of the pressing portion with respect to the object to be cleaned.
　これによって、押圧部が膜体で覆われて押圧部への汚れの付着が防止できる。さらに、押圧部の動きに膜体の変形吸収部が応動し、押圧部の進退動作に膜体が無理なく追従して被洗浄物に押圧力を作用させることができる。また、膜体が押圧部の動きに追従するときの抵抗を少なくして、加圧減圧部にかかる負荷を低く抑えることができる。 This allows the pressing portion to be covered with the film body, thereby preventing adhesion of dirt to the pressing portion. Further, the deformation absorbing portion of the film body responds to the movement of the pressing portion, and the film body can naturally follow the advancing and retreating operation of the pressing portion to apply a pressing force to the object to be cleaned. Further, the resistance when the film body follows the movement of the pressing portion can be reduced, and the load applied to the pressurizing and depressurizing portion can be suppressed low.

　第１の発明の洗濯機は、被洗浄物と洗浄水とを収容する洗浄槽と、洗浄槽の開口部を開閉する蓋体と、蓋体に設けられ、伸縮自在な押圧部と、押圧部を覆う膜体と、洗浄槽に収容された被洗浄物に対して押圧部を進退させる加圧減圧部と、加圧減圧部を制御する制御部とを備え、膜体は、可撓性を有する材料で構成され、膜体には押圧部の被洗浄物に対する進退に追従可能に変形する変形吸収部が設けられたものである。 According to a first aspect of the present invention, there is provided a washing machine comprising: a washing tank for storing an object to be washed and washing water; a lid for opening and closing an opening of the washing tank; A pressure-reducing unit that moves the pressing unit forward and backward with respect to the object to be cleaned stored in the cleaning tank, and a control unit that controls the pressure-reducing unit. The film body is provided with a deformation absorbing portion that deforms so as to be able to follow the advance and retreat of the pressing portion with respect to the object to be cleaned.
　これによって、押圧部は膜体で覆われ、蛇腹状の伸縮部が洗浄槽に対して露出することなく、押圧部を保護することができる。したがって、洗浄水に含まれる洗剤成分、または被洗浄物から洗い落とされた汚れ等が押圧部に付着することなく、清潔に保つことができる。また、押圧部の動きに膜体の変形吸収部が応動し、押圧部の進退動作に膜体が無理なく追従して被洗浄物に押圧力を作用させることができる。また、膜体が押圧部の動きに追従するときの抵抗を少なくすることができ、押圧部の伸縮動作を行う加圧減圧部にかかる負荷を低く抑えることができる。 Thereby, the pressing portion is covered with the film body, and the pressing portion can be protected without the bellows-like elastic portion being exposed to the cleaning tank. Therefore, it is possible to keep the detergent component contained in the washing water, or the dirt and the like washed off from the object to be washed, without adhering to the pressing portion, and to keep the washing portion clean. Also, the deformation absorbing portion of the film body responds to the movement of the pressing portion, and the film body can naturally follow the advancing / retreating operation of the pressing portion to apply a pressing force to the object to be cleaned. In addition, the resistance when the film body follows the movement of the pressing portion can be reduced, and the load on the pressurizing and depressurizing portion that performs the expanding and contracting operation of the pressing portion can be suppressed.
　第２の発明は、特に、第１の発明において、押圧部は、蓋体が開かれた状態で伸長可能に設けられ、膜体においては、押圧部の伸長にともなって変形吸収部が変形するものである。 In the second invention, in particular, in the first invention, the pressing portion is provided so as to be extendable with the lid opened, and in the membrane, the deformation absorbing portion is deformed as the pressing portion elongates. Things.
　これによって、洗濯が行われていない非使用時においては、蓋体を開いた状態で押圧部を伸長させることができる。また、膜体は、押圧部の伸長により付勢されて伸張する。これにより、使用者は、変形吸収部を伸びた状態にして、膜体に付着した水滴または汚れを容易に拭き取ることができる。 Thus, when not in use and washing is not being performed, the pressing portion can be extended with the lid opened. Further, the film body is urged and expanded by the expansion of the pressing portion. Accordingly, the user can easily wipe off water droplets or dirt attached to the film body with the deformation absorbing portion in an extended state.
　第３の発明は、特に、第１または第２の発明において、膜体は、開口を有する袋状に構成され、膜体の底部が押圧部の押圧面と対向するように押圧部に被せられ、膜体は洗浄槽の開口部の周縁と対向する蓋部に保持される周縁部を有し、変形吸収部は、膜体の底部と周縁部との間に位置し、押圧部の周囲を取り囲むように環状に構成されたものである。 In a third aspect of the present invention, in the first or second aspect, the film body is formed in a bag shape having an opening, and the film body is covered on the pressing portion such that a bottom portion of the film body faces a pressing surface of the pressing portion. The film body has a peripheral portion held by a lid portion facing the peripheral portion of the opening of the cleaning tank, and the deformation absorbing portion is located between the bottom portion and the peripheral portion of the film body. It is annularly configured to surround it.
　これによって、膜体は、押圧部の進退動作に無理なく追従して、被洗浄物に押圧力を作用させることができる。また、膜体が押圧部の動きに追従するときの抵抗を少なくすることができる。その結果、加圧減圧部にかかる負荷を低く抑えることができる。また、変形吸収部は、膜体の周縁部より内側に設けられることにより、変形時の抵抗を一層少なくすることができる。 Thus, the film body can naturally apply the pressing force to the object to be cleaned by following the forward / backward movement of the pressing portion. Further, the resistance when the film body follows the movement of the pressing portion can be reduced. As a result, the load on the pressurizing and depressurizing unit can be reduced. Further, since the deformation absorbing portion is provided inside the peripheral portion of the film body, the resistance at the time of deformation can be further reduced.
　第４の発明は、特に、第１～第３のいずれか１つの発明において、洗浄槽は、側壁部が洗浄槽の底部の周縁に連設され、開口部に向けて広がるように傾斜して設けられ、変形吸収部は、蓋体が閉じられたときに側壁部の上部と対向する位置に設けられたものである。 According to a fourth aspect of the present invention, in any one of the first to third aspects, the cleaning tank is provided such that a side wall portion is provided continuously with a peripheral edge of a bottom of the cleaning tank and is inclined so as to spread toward the opening. The deformation absorbing portion is provided at a position facing the upper portion of the side wall portion when the lid is closed.
　これによって、洗浄槽の底部に収容された被洗浄物の広い範囲に膜体を接触させることができ、被洗浄物をむらなく押圧することができる。 This allows the film body to come into contact with a wide range of the object to be cleaned accommodated in the bottom of the cleaning tank, so that the object to be cleaned can be pressed evenly.
　第５の発明は、特に、第３または第４の発明において、膜体は、周縁部において、洗浄槽と気密かつ水密にシールされたものである。 In a fifth aspect of the present invention, in the third or fourth aspect, the membrane is hermetically and water-tightly sealed to the cleaning tank at a peripheral portion.
　これによって、洗浄槽の開口部と、押圧部および膜体が設けられた蓋体とを確実にシール結合することができる。したがって、構成が簡略化される。 Thereby, the opening of the cleaning tank and the lid provided with the pressing portion and the membrane can be securely sealed and connected. Therefore, the configuration is simplified.
　第６の発明は、特に、第１～第５のいずれか１つの発明において、押圧部を複数有し、膜体は、複数の押圧部を内包するように構成されたものである。 The sixth invention is, in particular, any one of the first to fifth inventions, wherein the film has a plurality of pressing portions, and the film body is configured to include the plurality of pressing portions.
　これによって、洗濯が行われていない非使用時において、膜体は、複数の押圧部により支持されて、安定した状態となる。これにより、使用者は膜体に付着した汚れ等を容易に拭き取ることができる。また、交互に伸縮する押圧部間への被洗浄物の噛み込みを防止することができる。 Thus, at the time of non-use when washing is not performed, the film body is supported by the plurality of pressing portions and is in a stable state. This allows the user to easily wipe off dirt and the like adhering to the membrane. Further, it is possible to prevent the object to be cleaned from being caught between the pressing portions that expand and contract alternately.
　第７の発明は、特に、第１～第６のいずれか１つの発明において、膜体には、押圧部の押圧面と対向して凸部が設けられたものである。 According to a seventh invention, in particular, in any one of the first to sixth inventions, the film body is provided with a convex portion facing the pressing surface of the pressing portion.
　これによって、押圧部と接触することによって膜体が摩耗し、膜体の厚みが薄くなることが防止できる。したがって、膜体の耐久性を向上することができる。 Thus, it is possible to prevent the film body from being worn due to contact with the pressing portion and the film body from being thinned. Therefore, the durability of the film body can be improved.
　第８の発明は、特に、第１～第７のいずれか１つの発明において、膜体には、押圧部の押圧面と連結する連結部が設けられたものである。 In the eighth invention, in particular, in any one of the first to seventh inventions, the film body is provided with a connecting portion for connecting to the pressing surface of the pressing portion.
　これによって、押圧部が収縮する際に、膜体も押圧部の動きに追従して被洗浄物から離れる方向に移動する。このため、洗いステップ中の被洗浄物である衣類の膨張、収縮が容易になり、洗浄性能を向上させることができる。 Accordingly, when the pressing portion contracts, the film body also moves in a direction away from the object to be cleaned following the movement of the pressing portion. Therefore, the clothes to be cleaned are easily expanded and contracted during the washing step, and the cleaning performance can be improved.
　第９の発明は、特に、第１～第８のいずれか１つの発明において、被洗浄物から洗浄水を吸引する吸引部と、洗浄槽の内部に外気を導入する外気導入部とをさらに有し、制御部は、押圧部による被洗浄物の押圧と押圧解除により、被洗浄物を収縮膨張させて押し洗いを行う洗濯運転と、吸引部により洗浄水と導入された外気とを吸引して脱水を行う脱水運転と、の少なくともいずれか一方を実行するものである。 The ninth invention is, in particular, any one of the first to eighth inventions, further comprising a suction unit for sucking cleaning water from the object to be cleaned, and an outside air introduction unit for introducing outside air into the cleaning tank. Then, the control unit presses and releases the object to be cleaned by the pressing unit, and performs a washing operation in which the object to be cleaned is contracted and expanded to perform the press washing, and the suction unit suctions the cleaning water and the introduced outside air. And a dehydration operation for performing dehydration.
　これによって、被洗浄物に機械力を作用させて洗ったり、絞ったりすることが不向きな被洗浄物に対して、洗いステップでは、被洗浄物を押圧して押し洗いを行うことができる。脱水ステップでは、被洗浄物から洗浄水を吸引して吸引脱水を行うことができる。これにより、被洗浄物を痛めることなく、洗いと脱水との少なくともいずれか一方を効果的に行うことができる。 In this way, in the washing step, the object to be washed can be pressed and washed by pressing the object to be washed, which is not suitable for being washed or squeezed by applying mechanical force to the object to be washed. In the dehydration step, suction dehydration can be performed by suctioning cleaning water from the object to be cleaned. Thus, at least one of washing and dehydration can be effectively performed without damaging the object to be washed.

When the lid 5 is opened by the user, the lock device is unlocked in cooperation with the operation of the handle 5a (not shown).
　蓋体５の内側には、加圧減圧部７が設けられている。本実施の形態において、加圧減圧部７は、第１の加圧減圧部７ａと第２の加圧減圧部７ｂとで構成されている。具体的には、第１の加圧減圧部７ａは、押圧部８ａと加圧ポンプ１０ａと開閉弁１１ａとを含む。 加 圧 A pressurizing and depressurizing unit 7 is provided inside the lid 5. In the present embodiment, the pressurizing and depressurizing unit 7 includes a first pressurizing and depressurizing unit 7a and a second pressurizing and depressurizing unit 7b. Specifically, the first pressure reducing unit 7a includes a pressing unit 8a, a pressure pump 10a, and an on-off valve 11a.
　すなわち、加圧減圧部７ａは、押圧部８ａと、加圧ポンプ１０ａと、開閉弁１１ａとを含む。ここで、押圧部８ａは、例えば、ゴム、合成樹脂等で蛇腹状に形成された可撓性を有する袋状である。加圧ポンプ１０ａは、押圧部８ａにホース９ａを通して連通しており、押圧部８ａの内部に気体（例えば、空気など）、または液体（例えば、水、水溶液、またはオイル）などの流体を供給する。開閉弁１１ａは、開閉動作により、押圧部８ａに供給された流体の排出と停止を行う。 That is, the pressurizing and depressurizing unit 7a includes the pressing unit 8a, the pressurizing pump 10a, and the on-off valve 11a. Here, the pressing portion 8a is, for example, a bellows-shaped flexible bag made of rubber, synthetic resin, or the like. The pressure pump 10a communicates with the pressing portion 8a through a hose 9a, and supplies a fluid such as a gas (for example, air) or a liquid (for example, water, aqueous solution, or oil) to the inside of the pressing portion 8a. . The opening / closing valve 11a discharges and stops the fluid supplied to the pressing portion 8a by an opening / closing operation.
　また、上記加圧減圧部７ａと同様に、第２の加圧減圧部７ｂは、押圧部８ｂと、加圧ポンプ１０ｂと、開閉弁１１ｂとを含む。ここで、押圧部８ｂは、ゴム、合成樹脂等で蛇腹状に形成された可撓性を有する袋状である。加圧ポンプ１０ｂは、押圧部８ｂにホース９ｂを通して連通しており、押圧部８ｂの内部に気体または液体などの流体を供給する。開閉弁１１ｂは、開閉動作により、押圧部８ｂに供給された流体の排出と停止を行う。なお、本実施の形態では、洗濯機は２つの加圧減圧部の構成で説明するが、１つの加圧減圧部で構成してもよいし３つ以上の加圧減圧部で構成してもよい。 Furthermore, like the above-mentioned pressurizing and depressurizing unit 7a, the second pressurizing and depressurizing unit 7b includes a pressing unit 8b, a pressurizing pump 10b, and an on-off valve 11b. Here, the pressing portion 8b has a flexible bag shape formed in a bellows shape with rubber, synthetic resin, or the like. The pressurizing pump 10b communicates with the pressing portion 8b through a hose 9b, and supplies a fluid such as a gas or a liquid into the pressing portion 8b. The opening / closing valve 11b discharges and stops the fluid supplied to the pressing portion 8b by an opening / closing operation. In the present embodiment, the washing machine will be described with a configuration of two pressure reducing units, but may be configured with one pressure reducing unit or three or more pressure reducing units. Good.
　以降、複数を示すａ、ｂの符号については、特に区別の必要がない限りは省略して表記することもある。例えば、加圧減圧部７は、加圧減圧部７ａおよび加圧減圧部７ｂを示す。同様に、後述する、押圧部８、ホース９、加圧ポンプ１０、開閉弁１１、押圧面８０、伸縮部９０は、それぞれ、押圧部８ａおよび押圧部８ｂ、ホース９ａおよびホース９ｂ、加圧ポンプ１０ａおよび加圧ポンプ１０ｂ、開閉弁１１ａおよび開閉弁１１ｂ、押圧面８０ａおよび押圧面８０ｂ、伸縮部９０ａおよび伸縮部９０ｂを示す。 Hereinafter, the symbols a and b indicating a plurality may be abbreviated and described unless otherwise required. For example, the pressure reducing unit 7 indicates a pressure reducing unit 7a and a pressure reducing unit 7b. Similarly, a pressing portion 8, a hose 9, a pressure pump 10, an on-off valve 11, a pressing surface 80, and an expansion / contraction portion 90, which will be described later, are respectively a pressing portion 8a and a pressing portion 8b, a hose 9a and a hose 9b, and a pressure pump. 10a and a pressurizing pump 10b, an opening / closing valve 11a and an opening / closing valve 11b, a pressing surface 80a and a pressing surface 80b, a telescopic portion 90a and a telescopic portion 90b.
　加圧減圧部７は蓋体５の内側に並べて設けられている。押圧部８は、蓋体５の洗浄槽４側に取り付けられており、膨張および収縮する。すなわち、押圧部８は伸縮自在に設けられており、洗浄槽４の底部４ａに収容された被洗浄物２に対して進退自在に構成されている。押圧部８ａと押圧部８ｂの各々は、図３Ａおよび図３Ｂに示すように、被洗浄物２を押圧する押圧面８０ａ、８０ｂと、蛇腹状の伸縮部９０ａ、９０ｂとを有する。また、押圧部８ａ、８ｂにおいては、押圧面８０ａ、８０ｂが洗浄槽４の底部４ａに届く程度まで伸長する。 The pressure reducing unit 7 is provided side by side inside the lid 5. The pressing part 8 is attached to the cleaning tank 4 side of the lid 5 and expands and contracts. That is, the pressing portion 8 is provided so as to be extendable and retractable, and is configured to be able to advance and retreat with respect to the object to be cleaned 2 accommodated in the bottom 4 a of the cleaning tank 4. Each of the pressing portion 8a and the pressing portion 8b has, as shown in FIGS. 3A and 3B, pressing surfaces 80a and 80b for pressing the article to be cleaned 2, and bellows-like elastic portions 90a and 90b. In the pressing portions 8a and 8b, the pressing surfaces 80a and 80b extend to such an extent that the pressing surfaces 80a and 80b reach the bottom 4a of the cleaning tank 4.
　加圧減圧部７には、定圧開放弁（図示せず）が設けられている。定圧開放弁は、押圧部８の内部が所定の圧力になると開放して外部へ流体を排出する。これにより、押圧部８が所定の圧力を超えて加圧されることを防ぐ。なお、本実施の形態では、押圧部８の内部に供給される流体を、空気として説明する。 The pressure reducing unit 7 is provided with a constant pressure release valve (not shown). The constant pressure release valve opens when the inside of the pressing portion 8 reaches a predetermined pressure, and discharges the fluid to the outside. This prevents the pressing portion 8 from being pressed beyond a predetermined pressure. In the present embodiment, the fluid supplied to the inside of the pressing portion 8 will be described as air.
　押圧部８は、ゴム等の可撓性を有する材料で構成された膜体４１で覆われている。膜体４１は、被洗浄物２に押圧を繰り返し作用させるのに耐えうる十分な強度を確保した厚み（例えば、２～３ｍｍ）に設定されている。図５Ａに示されるように、膜体４１は、開口を有する袋状に形成されている。そして、膜体４１の底部４２が押圧部８の押圧面８０と対向するように、膜体４１は押圧部８に被せられている。さらに、押圧部８の押圧面８０と被洗浄物２との間に膜体４１の底部４２が位置するように、膜体４１は設けられている。ここで、膜体４１の開口に設けられた環状の周縁部４３においては、膜体４１は、外向きに開いた断面がコ字状（Ｃ字状）に形成されている。これにより、膜体４１は、周縁部４３が洗浄槽４の開口部３の周縁と対向する蓋部５ｂに嵌合されて、保持されている。 The pressing portion 8 is covered with a film body 41 made of a flexible material such as rubber. The film body 41 is set to a thickness (for example, 2 to 3 mm) that has sufficient strength to withstand repeated pressing of the object 2 to be cleaned. As shown in FIG. 5A, the film body 41 is formed in a bag shape having an opening. The film body 41 is covered on the pressing portion 8 such that the bottom portion 42 of the film body 41 faces the pressing surface 80 of the pressing portion 8. Further, the film body 41 is provided such that the bottom portion 42 of the film body 41 is located between the pressing surface 80 of the pressing portion 8 and the article 2 to be cleaned. Here, in the annular peripheral portion 43 provided at the opening of the film body 41, the film body 41 has a U-shaped (C-shaped) cross section opened outward. As a result, the film body 41 is held by being fitted to the lid 5b whose peripheral edge 43 faces the peripheral edge of the opening 3 of the cleaning tank 4.
　さらに、開口部３においては、膜体４１の周縁部４３に密閉部４４が設けられている。蓋体５が閉じられると、密閉部４４によって、洗浄槽４と蓋部５ｂとが気密かつ水密にシールされる。したがって、蓋部５ｂが閉じられた際に、洗浄槽４の内部は気密かつ水密の密閉された空間になる。これにより、洗い、すすぎ、および脱水の各ステップが実行される際に、水や空気が開口部３から外部に漏れることが防止される。 Further, in the opening 3, a sealing portion 44 is provided at the peripheral portion 43 of the film body 41. When the lid 5 is closed, the cleaning tank 4 and the lid 5b are hermetically and water-tightly sealed by the sealing portion 44. Therefore, when the lid 5b is closed, the inside of the cleaning tank 4 becomes an airtight and watertight sealed space. This prevents water and air from leaking from the opening 3 to the outside when the steps of washing, rinsing, and dehydrating are performed.
　膜体４１には、押圧部８が被洗浄物２に対して進退する方向へ伸縮する変形吸収部４５が設けられている。すわなち、変形吸収部４５は、押圧部８の進退動作に追従可能に変形する。また、変形吸収部４５は、膜体４１の底部４２と周縁部４３の間に位置し、蓋体５が閉じられたときに洗浄槽４の傾斜した側壁部４ｂの上方と対向する位置に設けられている。すなわち、変形吸収部４５は、押圧部８の周囲を取り囲むように環状に形成されており、押圧部８の伸縮にともなって変形する。 The film body 41 is provided with a deformation absorbing section 45 that expands and contracts in a direction in which the pressing section 8 advances and retreats with respect to the article 2 to be cleaned. That is, the deformation absorbing section 45 deforms so as to follow the forward / backward movement of the pressing section 8. Further, the deformation absorbing portion 45 is located between the bottom portion 42 and the peripheral edge portion 43 of the film body 41 and is provided at a position facing the upper side of the inclined side wall portion 4b of the cleaning tank 4 when the lid body 5 is closed. Have been. That is, the deformation absorbing portion 45 is formed in an annular shape so as to surround the periphery of the pressing portion 8, and is deformed as the pressing portion 8 expands and contracts.
　ここで、変形吸収部４５は、上方へ円弧状に膨らむように形成されている。また、膜体４１の周縁部４３より内側に位置するように、変形吸収部４５の断面形状がＳ字状（略Ｓ字状を含む）に設けられている。これにより、押圧部８の伸縮に追従して膜体４１が変形するときの抵抗を少なくすることができる。これに伴い、押圧部８ａ、８ｂを膨張収縮させる加圧減圧部７にかかる負荷が低く抑えられる。また、蓋体５には、解放穴４６が設けられ、膜体４１が形状変化した際に、蓋体５と膜体４１で囲われた内部の空気を外部に逃がすことができる。 Here, the deformation absorbing portion 45 is formed so as to bulge upward in an arc shape. Further, the cross-sectional shape of the deformation absorbing portion 45 is provided in an S-shape (including a substantially S-shape) so as to be located inside the peripheral portion 43 of the film body 41. Thereby, the resistance when the film body 41 is deformed following the expansion and contraction of the pressing portion 8 can be reduced. Along with this, the load on the pressurizing and depressurizing section 7 for expanding and contracting the pressing sections 8a and 8b can be suppressed low. Further, the cover 5 is provided with a release hole 46 so that when the shape of the film body 41 changes, air inside the cover 5 and the film body 41 can be released to the outside.
　また、蓋体５には、洗浄槽４に洗浄水を供給する給水経路１６が設けられている。給水経路１６には給水弁１４が設けられ、洗剤ケース１５を介して洗浄槽４の内部に連通している。したがって、給水弁１４が開閉されることにより、洗浄槽４の内部への水道水（洗浄水）の給水と停止が行われる。 蓋 Further, the lid 5 is provided with a water supply path 16 for supplying cleaning water to the cleaning tank 4. A water supply valve 14 is provided in the water supply path 16 and communicates with the inside of the cleaning tank 4 via a detergent case 15. Therefore, when the water supply valve 14 is opened and closed, the supply and stop of the tap water (wash water) to the inside of the washing tank 4 are performed.
　水位検知部１７は、洗浄槽４内に溜められた洗浄水の水位Ｗ（図３Ａおよび図３Ｂ参照）を検知する。水位検知部１７は、洗浄槽４の内部に連通して設けられている。例えば、水位検知部１７は、水位検知槽１８と、フロート１９と、水位スイッチ２０とを有している。水位検知槽１８は上方に開口部を有する槽である。フロート１９は、水位検知槽１８内の水位の変動に応じて上下動する。水位スイッチ２０は、フロート１９が所定の位置まで上昇したときに水位を検知する。 The water level detection unit 17 detects the water level W (see FIGS. 3A and 3B) of the cleaning water stored in the cleaning tank 4. The water level detector 17 is provided in communication with the inside of the cleaning tank 4. For example, the water level detection unit 17 includes a water level detection tank 18, a float 19, and a water level switch 20. The water level detecting tank 18 is a tank having an opening at the top. The float 19 moves up and down according to the fluctuation of the water level in the water level detection tank 18. The water level switch 20 detects the water level when the float 19 has risen to a predetermined position.
　洗浄槽４の底部４ａには、洗いステップ等で使用された洗浄水を排出する排水孔２１が形成されている。排水孔２１は、排水弁２２が設けられた排水経路２３に連通している。排水弁２２が開閉されることにより、洗浄槽４の内部の洗浄水の排水と停止が行われる。 排水 A drain hole 21 for discharging the washing water used in the washing step or the like is formed in the bottom 4 a of the washing tank 4. The drain hole 21 communicates with a drain passage 23 provided with a drain valve 22. The opening and closing of the drain valve 22 drains and stops the cleaning water in the cleaning tank 4.
　水槽部６には、溢水経路２４が設けられ、洗浄槽４内の水位が所定以上になったときに、洗浄槽４内の洗浄水を外部に排水する。溢水経路２４は、例えば、洗浄槽４の上部に溢水孔２４ａを有し、排水弁２２の下流側で排水経路２３と接続されている。 溢 An overflow path 24 is provided in the water tank section 6, and drains the cleaning water in the cleaning tank 4 to the outside when the water level in the cleaning tank 4 becomes higher than a predetermined level. The overflow path 24 has, for example, an overflow hole 24 a in the upper part of the washing tank 4, and is connected to the drain path 23 on the downstream side of the drain valve 22.
　さらに、溢水経路２４には、逆止弁（図示せず）が設けられている。逆止弁は、洗浄槽４内の洗浄水の排出方向では溢水経路２４を開放し、流入方向では溢水経路２４を封止するように構成されている。すなわち、逆止弁は、洗いステップおよびすすぎステップにおいては、溢水孔２４ａから流出した洗浄水を通過させて外部へ排出する。一方、逆止弁は、すすぎステップおよび脱水ステップでの脱水動作時においては、後述する吸引ポンプ２７で洗浄槽４内の空気が吸引された場合に、外気が洗浄槽４の内部へ流入することを防止するように構成されている。 The overflow path 24 is further provided with a check valve (not shown). The check valve is configured to open the overflow path 24 in the wash water discharge direction in the wash tank 4 and seal the overflow path 24 in the inflow direction. That is, in the washing step and the rinsing step, the check valve passes the washing water flowing out of the overflow hole 24a and discharges the washing water to the outside. On the other hand, during the dehydrating operation in the rinsing step and the dehydrating step, the outside air flows into the cleaning tank 4 when the air in the cleaning tank 4 is sucked by the suction pump 27 described later. It is configured to prevent
　洗浄槽４の底部４ａの中央部（略中央部を含む）には、吸引口２５が設けられている。吸引口２５は、洗浄槽４の内部に被洗浄物２がセットされたときに、被洗浄物２によって覆われる。吸引口２５に連通して脱水経路２６が設けられている。さらに、吸引ポンプ２７が脱水経路２６に連通して設けられている。吸引ポンプ２７によって被洗浄物２から洗浄水が吸引されると、洗浄槽４内の空気も吸引される。 吸引 A suction port 25 is provided at the center (including substantially the center) of the bottom 4a of the cleaning tank 4. The suction port 25 is covered by the object to be cleaned 2 when the object to be cleaned 2 is set inside the cleaning tank 4. A dehydration path 26 is provided in communication with the suction port 25. Further, a suction pump 27 is provided in communication with the dehydration path 26. When the washing water is sucked from the article 2 to be washed by the suction pump 27, the air in the washing tank 4 is also sucked.
　そのため、外気導入部２８によって、洗浄槽４内の空気の吸引時に、洗浄槽４の外部から洗浄槽４内に外気を導入する。外気導入部２８は、洗浄槽４の内部に溜められる洗浄水位より上方に開口が設けられていればよい。例えば、図１、図２、および、図４では、外気導入部２８は、洗浄槽４の内部と連通している水位検知部１７の上方側に設けられている。また、図３Ａおよび図３Ｂでは、外気導入部２８は、洗浄槽４の上方側に配設している。外気導入部２８には、導入される風量が調節可能な風量調整部である風量調整弁２９が設けられている。風量調整弁２９は、例えば、ニードルバルブのように流路に狭小な風路面積部を有し、吸引ポンプ２７が吸引する風量を調整することができる。なお、外気導入部２８によって、洗浄槽４内に導入される外気は、洗濯機１の外部から直接導入されてもよく、また、洗濯機１の内部空間を経由して導入されてもよい。 Therefore, outside air is introduced into the washing tank 4 from outside the washing tank 4 when the air in the washing tank 4 is sucked by the outside air introducing unit 28. The outside air introduction unit 28 may be provided with an opening above the cleaning water level stored in the cleaning tank 4. For example, in FIGS. 1, 2, and 4, the outside air introduction unit 28 is provided above the water level detection unit 17 communicating with the inside of the cleaning tank 4. 3A and 3B, the outside air introduction unit 28 is disposed above the cleaning tank 4. The outside air introduction unit 28 is provided with an air volume adjustment valve 29 which is an air volume adjustment unit capable of adjusting the volume of the introduced air. The air volume adjustment valve 29 has, for example, a narrow air path area in the flow path like a needle valve, and can adjust the air volume sucked by the suction pump 27. The outside air introduced into the washing tub 4 by the outside air introduction unit 28 may be directly introduced from outside the washing machine 1 or may be introduced via the internal space of the washing machine 1.
　脱水経路２６には、気液分離部３０が設けられている。気液分離部３０は、洗浄槽４内の空気と被洗浄物２から吸引した洗浄水とを分離し、吸引した洗浄水を貯水する。気液分離部３０は、例えば、耐圧容器で構成され、一次側通風口３３と、二次側通風口３１とを備えている。一次側通風口３３は、吸引経路３２を通して吸引ポンプ２７と連通する。二次側通風口３１は、上方に脱水経路２６と連通する。さらに、一次側通風口３３と二次側通風口３１との間に障壁３４が設けられている。障壁３４は、気液分離部３０の天面から下方へ突出して形成する。これにより、二次側通風口３１から気液分離部３０内に吸引された洗浄水が、一次側通風口３３に侵入することを防止する。 気 A gas-liquid separation unit 30 is provided in the dehydration path 26. The gas-liquid separation unit 30 separates the air in the cleaning tank 4 from the cleaning water sucked from the object to be cleaned 2 and stores the suctioned cleaning water. The gas-liquid separation unit 30 is formed of, for example, a pressure-resistant container, and includes a primary side ventilation port 33 and a secondary side ventilation port 31. The primary side ventilation port 33 communicates with the suction pump 27 through the suction path 32. The secondary side ventilation port 31 communicates with the dehydration path 26 upward. Further, a barrier 34 is provided between the primary side ventilation port 33 and the secondary side ventilation port 31. The barrier 34 is formed to protrude downward from the top surface of the gas-liquid separation unit 30. This prevents the washing water sucked into the gas-liquid separation unit 30 from the secondary vent 31 from entering the primary vent 33.
　脱水排水口３５は、気液分離部３０の底部に設けられている。脱水排水口３５は、開閉自在な脱水排水弁３６を有する脱水排水経路３７に連通している。 The dewatering drain 35 is provided at the bottom of the gas-liquid separation unit 30. The dewatering drainage port 35 communicates with a dewatering drainage path 37 having a dewatering drainage valve 36 that can be opened and closed.
　溢水検知部３８は、気液分離部３０の内壁の所定の高さに設けられている。具体的には、溢水検知部３８が設けられる高さ位置は、気液分離部３０に貯水可能な最大水位に対して１／２から４／５の範囲内が望ましい。 The overflow detector 38 is provided at a predetermined height on the inner wall of the gas-liquid separator 30. Specifically, the height position at which the overflow detection unit 38 is provided is desirably within a range of か ら to ／ of the maximum water level that can be stored in the gas-liquid separation unit 30.
　溢水検知部３８は、例えば、１対の電極等で構成される。溢水検知部３８が、気液分離部３０の内部に貯水された洗浄水が所定量に達したことを検知すると脱水排水弁３６が開かれる。これにより、洗浄水は脱水排水経路３７を通して洗濯機１の外部へ排水される。 The overflow detecting unit 38 is composed of, for example, a pair of electrodes and the like. When the overflow detecting unit 38 detects that the washing water stored in the gas-liquid separating unit 30 has reached a predetermined amount, the dewatering drain valve 36 is opened. As a result, the washing water is drained to the outside of the washing machine 1 through the dewatering drainage channel 37.
　ここで、洗浄水に泡が含まれる場合、泡が障壁３４に付着して残ると臭いの要因になる。この泡残りを防ぐために、溢水検知部３８は、洗浄水が検知されたときに、障壁３４の下端と洗浄水面との間に一定空間が存在するように設けられている。すわなち、溢水検知部３８は、洗浄水に含まれる泡の量を考慮した所定量を検知する。 Here, when bubbles are contained in the cleaning water, if the bubbles adhere to and remain on the barrier 34, they cause odor. In order to prevent the remaining of the bubbles, the overflow detector 38 is provided such that a certain space exists between the lower end of the barrier 34 and the cleaning water surface when the cleaning water is detected. That is, the overflow detector 38 detects a predetermined amount in consideration of the amount of bubbles contained in the cleaning water.
　制御部３９は、蓋体５の内部の側面部に配設されている。また、操作表示部４０が制御部３９の上面に設けられている。制御部３９は、入力される情報に基づいて、各種構成要素を制御して、洗濯運転を実行する。 The control unit 39 is provided on a side surface inside the lid 5. An operation display unit 40 is provided on the upper surface of the control unit 39. The control unit 39 controls various components based on the input information to execute the washing operation.
　具体的には、制御部３９には、水位検知部１７で検知した洗浄槽４内の洗浄水の水位、溢水検知部３８で検知した気液分離部３０内の洗浄水の量などの情報が入力される。 Specifically, the control unit 39 stores information such as the level of the cleaning water in the cleaning tank 4 detected by the water level detecting unit 17 and the amount of the cleaning water in the gas-liquid separation unit 30 detected by the overflow detecting unit 38. Is entered.
　そして、制御部３９は、それらの入力情報に基づいて、加圧ポンプ１０、開閉弁１１、給水弁１４、排水弁２２、吸引ポンプ２７、風量調整弁２９、脱水排水弁３６等を制御し、洗いステップ、すすぎステップおよび脱水ステップを制御して洗濯運転を実行する。なお、後述するように、本実施の形態においては、洗濯コースは、洗いステップ、すすぎステップおよび脱水ステップの少なくとも一つから構成されている。 Then, the control unit 39 controls the pressurizing pump 10, the on-off valve 11, the water supply valve 14, the drain valve 22, the suction pump 27, the air volume adjusting valve 29, the dewatering drain valve 36, and the like based on the input information. The washing operation is executed by controlling the washing step, the rinsing step and the dehydration step. As will be described later, in the present embodiment, the washing course includes at least one of a washing step, a rinsing step, and a dehydrating step.
　ここで、押圧部８は、蓋体５が開かれた状態で伸長可能に構成されている。そのため、押圧部８には、押圧部８の伸長動作を設定する伸長設定部（図示せず）が設けられている。伸長設定部は、蓋体５が開かれた状態において、使用者の手動操作により押圧部８を加圧する。これにより、蛇腹状の伸縮部８ｄが伸びた状態となり、押圧部８が伸長する。伸長設定部は、洗濯運転時に各種の設定を行う操作表示部４０に設けられている。なお、伸長設定部は、操作表示部４０とは別に設けられてもよい。 Here, the pressing portion 8 is configured to be extendable with the lid 5 opened. Therefore, the pressing unit 8 is provided with an extension setting unit (not shown) for setting the extension operation of the pressing unit 8. The extension setting unit presses the pressing unit 8 by manual operation of the user in a state where the lid 5 is opened. As a result, the bellows-shaped expansion / contraction part 8d is in an extended state, and the pressing part 8 is extended. The extension setting unit is provided in the operation display unit 40 for performing various settings during the washing operation. The extension setting unit may be provided separately from the operation display unit 40.
　以上のように構成された洗濯機１について、以下、その動作、作用を説明する。 The operation and operation of the washing machine 1 configured as described above will be described below.
　最初に、使用者は、蓋体５の上面前部に設けられた操作表示部４０から、洗濯コースの選択や各ステップの時間等の設定内容を入力する。制御部３９は、設定内容に基づいて、洗いステップ、すすぎステップ、脱水ステップの各ステップの動作を洗濯コースとして実行する。このとき、使用者は、洗いステップのみを実行するなど、洗濯コースを任意に選択することができる。なお、使用者は、この設定作業を、後述する被洗浄物２をセットした後に行ってもよい。 First, the user inputs the setting contents such as the selection of the washing course and the time of each step from the operation display unit 40 provided at the front part of the upper surface of the lid 5. The control unit 39 executes the operations of the washing step, the rinsing step, and the dehydration step as a washing course based on the settings. At this time, the user can arbitrarily select a washing course, such as executing only the washing step. Note that the user may perform this setting operation after setting the article to be cleaned 2 described later.
　使用者は、ハンドル５ａを操作してロック装置を解錠した後、蓋体５を開いて洗浄槽４の底部４ａに被洗浄物２の形を整えてセットする。なお、使用者は、被洗浄物２の大きさによっては、折り畳んで被洗浄物２をセットしてもよい。被洗浄物２のセットが完了し、蓋体５が閉じられ、ロック装置が施錠されると、膜体４１の周縁部４３に設けられた密閉部４４によって洗浄槽４が密閉された状態となる。そして、制御部３９は、操作表示部４０で設定された運転コースに応じて運転を開始する。 After the user operates the handle 5a to unlock the lock device, the lid 5 is opened, and the shape of the article 2 to be washed is adjusted and set on the bottom 4a of the washing tank 4. The user may fold and set the object 2 depending on the size of the object 2 to be cleaned. When the setting of the object to be cleaned 2 is completed, the lid 5 is closed, and the locking device is locked, the cleaning tank 4 is sealed by the sealing portion 44 provided on the peripheral portion 43 of the film body 41. . Then, the control unit 39 starts driving according to the driving course set on the operation display unit 40.
　なお、蓋体５が閉じられるとき、膜体４１が洗浄槽４の開口部３を通過する過程において、押圧部８が加圧されない状態で、膜体４１は洗浄槽４の底部４ａにセットされた被洗浄物２に接触する。そして、蓋体５が閉まるにつれて、被洗浄物２との接触度合いが増え、膜体４１は押し戻されるように変形する。このとき、膜体４１には変形吸収部４５が設けられているので、膜体４１が外側に膨らんで、蓋体５と開口部３とでできる隙間に噛み込んだりすることが防止される。すなわち、変形吸収部４５の形状が変化することにより、蓋体５を無理なく確実に閉じることができる。 When the lid 5 is closed, the film 41 is set on the bottom 4a of the cleaning tank 4 in a state where the pressing unit 8 is not pressurized while the film 41 passes through the opening 3 of the cleaning tank 4. The object to be cleaned 2 contacts. Then, as the lid 5 closes, the degree of contact with the object 2 to be cleaned increases, and the film 41 is deformed so as to be pushed back. At this time, since the film body 41 is provided with the deformation absorbing portion 45, the film body 41 is prevented from swelling outward and biting into the gap formed between the lid 5 and the opening 3. That is, by changing the shape of the deformation absorbing portion 45, the lid 5 can be closed securely without any difficulty.
　はじめに、洗濯コースとして、洗いステップのみが設定された場合の洗濯機１の動作および作用について、説明する。 First, an operation and an action of the washing machine 1 when only a washing step is set as a washing course will be described.
　制御部３９は、洗いステップを実行する。洗いステップは、給水動作および洗い動作から構成される。制御部３９は、初めに給水弁１４を開放して給水動作を行う。これにより、洗浄水として水道水と、洗剤ケース１５に投入されている洗剤とが、給水経路１６から洗浄槽４の内部に供給される。このとき、洗浄水は徐々に被洗浄物２に浸透し、被洗浄物２の繊維の間に含まれた状態となる。 (4) The control unit 39 executes a washing step. The washing step includes a water supply operation and a washing operation. The control unit 39 first performs a water supply operation by opening the water supply valve 14. As a result, the tap water as the washing water and the detergent put in the detergent case 15 are supplied from the water supply path 16 into the inside of the washing tank 4. At this time, the cleaning water gradually penetrates into the object 2 to be washed and is contained between the fibers of the object 2 to be washed.
　そして、制御部３９は、水位検知部１７の水位スイッチ２０により、洗浄水が洗浄槽４の内部に所定水位まで供給されたことを検知して、給水弁１４を閉止する。 制 御 Then, the control unit 39 detects that the washing water has been supplied to the inside of the washing tank 4 to the predetermined water level by the water level switch 20 of the water level detecting unit 17, and closes the water supply valve 14.
　制御部３９は、給水動作が終わると、洗い動作を実行する。洗い動作においては、制御部３９は、まず、第１の加圧減圧部７ａの開閉弁１１ａを閉じて加圧ポンプ１０ａを所定時間、又は、押圧部８ａが所定圧に到達するまで駆動する。これにより、押圧部８ａの内部に空気が供給されて、押圧部８ａは膨張する。図３Ａに示されるように、伸縮部９０ａが伸長し、押圧部８ａが被洗浄物２に向かって伸びる。その結果、押圧部８ａの下方の被洗浄物２は、膜体４１を介して押圧面８０ａで押圧された部分が圧縮され、厚みが薄くなる。 (4) When the water supply operation is completed, the control unit 39 executes the washing operation. In the washing operation, the control unit 39 first closes the on-off valve 11a of the first pressurizing and depressurizing unit 7a and drives the pressurizing pump 10a for a predetermined time or until the pressing unit 8a reaches a predetermined pressure. Thereby, air is supplied to the inside of the pressing portion 8a, and the pressing portion 8a expands. As shown in FIG. 3A, the elastic portion 90 a extends, and the pressing portion 8 a extends toward the object 2 to be cleaned. As a result, the portion of the cleaning target 2 below the pressing portion 8a pressed by the pressing surface 80a via the film body 41 is compressed, and the thickness thereof is reduced.
　押圧部８ａの膨張により被洗浄物２が圧縮されて体積変化することに伴い、被洗浄物２の内部に含まれる洗浄水は、被洗浄物２から押し出される。これによって、被洗浄物２の内部で水流が発生し、被洗浄物２に付着していた汚れがその水流により繊維から離れて除去される。 (4) The cleaning water contained in the cleaning target 2 is pushed out of the cleaning target 2 as the cleaning target 2 is compressed by the expansion of the pressing portion 8a and changes in volume. As a result, a water flow is generated inside the object 2 to be cleaned, and the dirt adhering to the object 2 to be cleaned is separated away from the fibers by the water flow.
　このとき、制御部３９は、第２の加圧減圧部７ｂの開閉弁１１ｂを開放し、押圧部８ｂを収縮可能にする。したがって、被洗浄物２の内部に含まれる洗浄水は、被洗浄物２の内部で押圧部８ａの下方から押圧部８ｂの下方へ矢印Ａ（図３Ａ参照）で示される方向へ移動する。そして、このように移動する洗浄水は、押圧部８ｂの下方の被洗浄物２を膨張させながら押圧部８ｂの押圧面８０ｂを上方へ押し上げる。これにより、開放されている開閉弁１１ｂから空気が排出されて、押圧部８ｂが収縮する。 At this time, the control unit 39 opens the on-off valve 11b of the second pressurizing and depressurizing unit 7b, and makes the pressing unit 8b contractable. Therefore, the cleaning water contained in the cleaning target 2 moves from below the pressing portion 8a to below the pressing portion 8b in the cleaning target 2 in the direction indicated by the arrow A (see FIG. 3A). The cleaning water thus moved pushes the pressing surface 80b of the pressing portion 8b upward while expanding the object 2 to be cleaned below the pressing portion 8b. As a result, air is discharged from the open / closed valve 11b, and the pressing portion 8b contracts.
　次に、制御部３９は、第２の加圧減圧部７ｂの開閉弁１１ｂを閉じて加圧ポンプ１０ｂを所定時間、又は、押圧部８ｂが所定圧に到達するまで駆動する。これにより、押圧部８ｂの内部に空気が供給されて、押圧部８ｂが膨張する。 Next, the control unit 39 closes the on-off valve 11b of the second pressurizing and depressurizing unit 7b and drives the pressurizing pump 10b for a predetermined time or until the pressing unit 8b reaches a predetermined pressure. Thereby, air is supplied to the inside of the pressing portion 8b, and the pressing portion 8b expands.
　図３Ｂに示されるように、伸縮部９０ｂが伸長し、押圧部８ｂが被洗浄物２に向かって伸びると、押圧部８ｂの下方の被洗浄物２は、膜体４１を介して押圧面８０ｂで押圧された部分が圧縮され、厚みが薄くなる。 As shown in FIG. 3B, when the expansion and contraction portion 90b extends and the pressing portion 8b extends toward the cleaning target 2, the cleaning target 2 below the pressing portion 8b moves through the pressing surface 80b via the film body 41. The part pressed by is compressed and the thickness is reduced.
　押圧部８ｂの膨張により被洗浄物２が圧縮されて体積変化することに伴い、被洗浄物２の内部に含まれる洗浄水は、被洗浄物２から押し出される。これによって、被洗浄物２の内部で水流が発生し、被洗浄物２に付着していた汚れがその水流により繊維から離れて除去される。 (4) The cleaning water contained in the cleaning target 2 is pushed out from the cleaning target 2 as the cleaning target 2 is compressed and changes in volume due to the expansion of the pressing portion 8b. As a result, a water flow is generated inside the object 2 to be cleaned, and the dirt adhering to the object 2 to be cleaned is separated away from the fibers by the water flow.
　このとき、制御部３９は、第１の加圧減圧部７ａの開閉弁１１ａを開放し、押圧部８ａを収縮可能にする。したがって、被洗浄物２の内部に含まれる洗浄水は、被洗浄物２の内部で押圧部８ｂの下方から押圧部８ａの下方へ矢印Ｂ（図３Ｂ参照）で示される方向へ移動する。そして、このように移動する洗浄水は、押圧部８ａの下方の被洗浄物２を膨張させながら押圧部８ａの押圧面８０ａを上方へ押し上げる。これにより、開放されている開閉弁１１ａから空気が排出されて、押圧部８ａが収縮する。 At this time, the control unit 39 opens the on-off valve 11a of the first pressurizing and depressurizing unit 7a, and enables the pressing unit 8a to contract. Therefore, the cleaning water contained in the cleaning target 2 moves from below the pressing portion 8b to below the pressing portion 8a in the cleaning target 2 in the direction indicated by the arrow B (see FIG. 3B). The cleaning water thus moved pushes the pressing surface 80a of the pressing portion 8a upward while expanding the object 2 to be cleaned below the pressing portion 8a. As a result, air is discharged from the open / close valve 11a, and the pressing portion 8a contracts.
　このように、洗い動作では、押圧部８ａと押圧部８ｂを交互となる異なるタイミングで膨張と収縮（例えば、押圧部８ａの膨張による加圧１秒間、押圧部８ｂの収縮による減圧１秒間）を所定時間（例えば、１０分間）繰り返すことにより、被洗浄物２に対して押し洗い効果を発揮させることができる。すなわち、被洗浄物２に撹拌または叩き洗い等による機械力が作用することなく、被洗浄物２の内部に多方向の水流を発生させて汚れを除去することができる。 As described above, in the washing operation, the pressing portion 8a and the pressing portion 8b are expanded and contracted at different alternate timings (for example, pressurization for 1 second due to expansion of the pressing portion 8a and pressure reduction for 1 second due to contraction of the pressing portion 8b). By repeating the process for a predetermined period of time (for example, 10 minutes), it is possible to exert a push-washing effect on the article 2 to be cleaned. That is, it is possible to remove dirt by generating a multi-directional water flow inside the object 2 to be cleaned without applying mechanical force such as stirring or slap washing to the object 2 to be cleaned.
　この際、押圧部８ａ、８ｂを内包するように膜体４１が設けられているため、２つの押圧部８ａ、８ｂの間に被洗浄物２を噛みこむことを防ぐことができる。また、押圧部８ａ、８ｂにおいては、蛇腹状の伸縮部９０ａ、９０ｂが膜体４１によって覆われているため、伸縮部９０ａ、９０ｂが洗浄槽４内の汚れを含む洗浄水に触れることなく、清潔に保つことができる。さらに、膜体４１に付着する水滴または汚れも、使用者によって容易に拭き取ることができて清潔に保つことができる。 At this time, since the film body 41 is provided so as to include the pressing portions 8a and 8b, it is possible to prevent the cleaning target 2 from being caught between the two pressing portions 8a and 8b. Further, in the pressing portions 8a, 8b, since the bellows-like elastic portions 90a, 90b are covered with the film body 41, the elastic portions 90a, 90b do not come into contact with the cleaning water containing dirt in the cleaning tank 4, It can be kept clean. Further, water droplets or dirt adhering to the film body 41 can be easily wiped off by the user and can be kept clean.
　以上のように、洗濯コースとして、洗いステップのみが実行される場合について説明した。 As described above, the case where only the washing step is executed as the washing course has been described.
　次に、洗いステップから脱水ステップまでを一貫して実行する洗濯コースが設定された場合について説明する。制御部３９は、上述の洗いステップに続いて、以下に説明する、すすぎステップ、および脱水ステップを実行する。 Next, a case where a washing course in which the washing step to the dehydrating step are executed consistently is set will be described. The control unit 39 executes a rinsing step and a dehydrating step described below, following the washing step described above.
　すすぎステップでは、例えば、脱水動作の後、ためすすぎ動作が行われる。以下、すすぎステップにおける脱水動作を中間脱水動作と記す。後述するように、脱水ステップにおいても脱水動作が行われる。この脱水ステップにおける脱水動作を最終脱水動作と称し、すすぎステップにおける中間脱水動作と区別する。 In the rinsing step, for example, a spin rinsing operation is performed after the dehydration operation. Hereinafter, the dehydration operation in the rinsing step is referred to as an intermediate dehydration operation. As described later, a dehydration operation is also performed in the dehydration step. The dehydration operation in this dehydration step is called a final dehydration operation, and is distinguished from the intermediate dehydration operation in the rinsing step.
　なお、すすぎステップは、複数回繰り返しても構わない。中間脱水動作は、複数回繰り返されるすすぎステップの間に行われてもよい。 The rinsing step may be repeated a plurality of times. The intermediate dewatering operation may be performed during a plurality of repeated rinsing steps.
　中間脱水動作は、排水、圧縮、吸引を含む。まず、制御部３９によって排水が行われる。つまり、制御部３９によって、排水弁２２が開放され、洗浄槽４の内部の洗浄水が排水孔２１から排水経路２３を通して洗濯機１の外部に排水される。 Intermediate dehydration operation includes drainage, compression, and suction. First, drainage is performed by the control unit 39. That is, the drain valve 22 is opened by the control unit 39, and the washing water inside the washing tank 4 is drained from the drain hole 21 to the outside of the washing machine 1 through the drain path 23.
　排水が終わると、制御部３９によって圧縮が行われる。つまり、制御部３９によって、排水弁２２が開放された状態で、開閉弁１１ａ、１１ｂが閉じられて加圧ポンプ１０ａ、１０ｂが駆動される。これにより、押圧部８ａ、８ｂの膨張により被洗浄物２が押圧されて圧縮され、被洗浄物２が含んでいる洗浄水の一部が強制的に排出される。 When drainage is completed, compression is performed by the control unit 39. That is, the control unit 39 closes the on-off valves 11a and 11b and drives the pressurizing pumps 10a and 10b with the drain valve 22 opened. As a result, the cleaning target 2 is pressed and compressed by the expansion of the pressing portions 8a and 8b, and a part of the cleaning water contained in the cleaning target 2 is forcibly discharged.
　圧縮が終わると、制御部３９によって吸引が行われる。つまり、制御部３９によって、被洗浄物２が押圧された状態で、排水弁２２が閉じられて、吸引ポンプ２７が駆動される。これにより、風量調整弁２９を介して、外気導入部２８から洗浄槽４の内部に外気が導入される。導入された外気により、洗浄槽４内の洗浄水と空気が、吸引口２５から吸引され、脱水経路２６を通して、気液分離部３０に運ばれる。さらに、吸引された空気は、吸引ポンプ２７によって、洗濯機１の外部へ排出される。一方、洗浄水は、気液分離部３０に溜められる。これにより、被洗浄物２の脱水が進行する。 When the compression is completed, suction is performed by the control unit 39. That is, the drain valve 22 is closed and the suction pump 27 is driven in a state where the object to be cleaned 2 is pressed by the control unit 39. Thereby, outside air is introduced into the inside of the washing tank 4 from the outside air introduction unit 28 via the air volume adjustment valve 29. The cleaning water and air in the cleaning tank 4 are sucked from the suction port 25 by the introduced outside air, and are conveyed to the gas-liquid separation unit 30 through the dehydration path 26. Further, the sucked air is discharged to the outside of the washing machine 1 by the suction pump 27. On the other hand, the washing water is stored in the gas-liquid separation unit 30. Thereby, dehydration of the article to be cleaned 2 proceeds.
　すすぎステップにおいて、中間脱水動作のつぎに、制御部３９によって溜めすすぎ動作が行われる。まず、制御部３９は給水を行う。制御部３９によって、給水弁１４が開放され、洗浄槽４の内部に所定量の洗浄水が供給される。このとき、洗剤ケース１５内の洗剤は、上述の洗いステップですべて使用済みである。したがって、溜めすすぎ動作時の洗浄水は、水道水である。 In the rinsing step, the control section 39 performs a reservoir rinsing operation after the intermediate dehydration operation. First, the control unit 39 supplies water. The water supply valve 14 is opened by the control unit 39, and a predetermined amount of cleaning water is supplied into the cleaning tank 4. At this time, all the detergent in the detergent case 15 has been used in the above-described washing step. Therefore, the washing water during the pool rinsing operation is tap water.
　その後、洗い動作と同様に、加圧ポンプ１０ａ、１０ｂが駆動され、押圧部８ａ、８ｂの膨張と収縮が交互に繰り返される。これにより、被洗浄物２の内部の洗浄水の洗剤濃度が希釈される。以上で、すすぎステップが終了する。 Then, similarly to the washing operation, the pressurizing pumps 10a and 10b are driven, and the expansion and contraction of the pressing portions 8a and 8b are alternately repeated. As a result, the detergent concentration of the cleaning water inside the article to be cleaned 2 is diluted. Thus, the rinsing step ends.
　このすすぎステップが複数回（例えば、２回）繰り返される。このとき、１回目のすすぎステップと、２回目のすすぎステップの間においても、上記と同様の中間脱水動作が実行される。 The rinsing step is repeated a plurality of times (for example, twice). At this time, the same intermediate dehydration operation as described above is executed between the first rinsing step and the second rinsing step.
　つぎに、制御部３９は、上記のすすぎステップを実行した後、脱水ステップを実行する。 Next, after executing the above-described rinsing step, the control unit 39 executes a dehydration step.
　脱水ステップでは、脱水動作が行われる。以下、脱水ステップにおける脱水動作を最終脱水動作と記す。最終脱水動作は、排水、圧縮、吸引を含む。 脱水 In the dehydration step, a dehydration operation is performed. Hereinafter, the dehydration operation in the dehydration step is referred to as a final dehydration operation. Final dewatering operations include draining, compressing, and suctioning.
　まず、制御部３９は、すすぎステップで使用した洗浄水の排水を行う。つまり、制御部３９によって、排水弁２２が開放され、洗浄槽４の内部の洗浄水が排水孔２１から排水経路２３を通して洗濯機１の外部に排水される。このとき、制御部３９によって、外気導入部２８が開放されて洗浄槽４の内部が外部と連通される。その結果、洗浄水は円滑に排出される。なお、制御部３９によって、風量調整弁２９は開かれており、開閉弁１１ａ、１１ｂは両方とも閉じられており、脱水排水弁３６は閉じられている。 First, the control unit 39 drains the washing water used in the rinsing step. That is, the drain valve 22 is opened by the control unit 39, and the washing water inside the washing tank 4 is drained from the drain hole 21 to the outside of the washing machine 1 through the drain path 23. At this time, the outside air introduction part 28 is opened by the control part 39, and the inside of the washing tank 4 is communicated with the outside. As a result, the washing water is discharged smoothly. The control unit 39 opens the air volume adjusting valve 29, closes both the open / close valves 11a and 11b, and closes the dewatering / drainage valve 36.
　制御部３９は、排水の完了後、圧縮を行う。つまり、制御部３９によって、排水弁２２が開放され、開閉弁１１ａ、１１ｂが両方とも閉じられた状態で、加圧ポンプ１０ａ、１０ｂが両方ともほぼ同時（同時を含む）に駆動される。これにより、押圧部８ａ、８ｂの内部に空気が供給され、押圧部８ａ、８ｂの膨張により被洗浄物２が押圧されて圧縮される。したがって、被洗浄物２が含んでいる洗浄水の一部が強制的に排出され、排水孔２１から排水経路２３を通して洗濯機１の外部に排水される。このような押圧部８の構成および作用により、膜体４１を介して、被洗浄物２に押圧面８０を密着させて均一に押圧することができる。すなわち、被洗浄物２の内部に含まれた洗浄水を強制的に押し出すことができる。 (4) The control unit 39 performs compression after drainage is completed. That is, both the pressurizing pumps 10a and 10b are driven substantially simultaneously (including simultaneously) in a state where the drain valve 22 is opened and both the on-off valves 11a and 11b are closed by the control unit 39. As a result, air is supplied to the inside of the pressing portions 8a and 8b, and the to-be-cleaned object 2 is pressed and compressed by the expansion of the pressing portions 8a and 8b. Therefore, a part of the washing water contained in the article to be washed 2 is forcibly discharged and drained from the drain hole 21 to the outside of the washing machine 1 through the drain path 23. With such a configuration and operation of the pressing portion 8, the pressing surface 80 can be brought into close contact with the article 2 to be cleaned via the film body 41 and can be pressed uniformly. That is, the cleaning water contained in the object 2 can be forcibly pushed out.
　圧縮が終わると、制御部３９は、吸引を行う。つまり、制御部３９によって、加圧ポンプ１０ａ、１０ｂを停止させてから所定時間Ｔ１（例えば、１分）後、被洗浄物２が押圧された状態で排水弁２２が閉じられ、吸引ポンプ２７が駆動される。これにより、洗浄槽４内部の空気と水が気液分離部３０内に吸引される。この際、図４に示されるように、洗浄槽４は大気より減圧され、膜体４１は圧力差によって被洗浄物２を押圧する。外気導入部２８から洗浄槽４の内部に外気が導入され、膜体４１を介して押圧された被洗浄物２の内部に外気が侵入する。洗浄槽４内部の圧力は、例えば、定圧開放弁等によって所定の圧力に保たれ、被洗浄物２は一定の圧力で加圧された状態が維持される。 (4) When the compression is completed, the control unit 39 performs suction. That is, after a predetermined time T1 (for example, one minute) from stopping the pressurizing pumps 10a and 10b by the control unit 39, the drain valve 22 is closed in a state where the cleaning target 2 is pressed, and the suction pump 27 is turned off. Driven. Thereby, the air and water inside the cleaning tank 4 are sucked into the gas-liquid separation unit 30. At this time, as shown in FIG. 4, the pressure in the cleaning tank 4 is reduced from the atmosphere, and the film body 41 presses the object 2 to be cleaned by a pressure difference. Outside air is introduced from the outside air introduction unit 28 into the cleaning tank 4, and the outside air enters the inside of the cleaning target 2 pressed through the film body 41. The pressure inside the cleaning tank 4 is maintained at a predetermined pressure by, for example, a constant-pressure release valve or the like, and the object to be cleaned 2 is maintained at a constant pressure.
　外気導入部２８から洗浄槽４の内部に導入された外気は、被洗浄物２の繊維の間に留まっている洗浄水を押し出す。そして、外気は洗浄水と一緒に吸引され、吸引口２５へ移動する。外気によって吸引口２５まで運ばれた洗浄水は、表面張力により繊維に留まろうとする。しかし、洗浄水は気流によるせん断力によって繊維から分離し、吸引口２５から脱水経路２６を通して気液分離部３０へ運ばれる。 (4) The outside air introduced into the inside of the washing tank 4 from the outside air introduction unit 28 pushes out the washing water remaining between the fibers of the article 2 to be washed. Then, the outside air is sucked together with the cleaning water and moves to the suction port 25. The cleaning water carried to the suction port 25 by the outside air tends to stay on the fiber due to surface tension. However, the washing water is separated from the fibers by the shearing force of the airflow, and is conveyed from the suction port 25 to the gas-liquid separation unit 30 through the dehydration path 26.
　洗浄水とともに吸引された空気は、二次側通風口３１から気液分離部３０へ入り、気液分離部３０の上部に設けられた一次側通風口３３から吸引ポンプ２７により排出される。また、洗浄水は、二次側通風口３１から重力により落下し、一次側通風口３３と二次側通風口３１との間に設けられた障壁３４によって一次側通風口３３に侵入することなく、気液分離部３０に貯水される。 The air sucked together with the washing water enters the gas-liquid separator 30 through the secondary vent 31 and is discharged by the suction pump 27 from the primary vent 33 provided above the gas-liquid separator 30. Further, the washing water drops from the secondary-side ventilation port 31 due to gravity, and does not enter the primary-side ventilation port 33 by the barrier 34 provided between the primary-side ventilation port 33 and the secondary-side ventilation port 31. The water is stored in the gas-liquid separation unit 30.
　ここで、洗浄槽４の内部の洗浄水と空気とが吸引されると、これらは最も抵抗の少ない経路を通過する。したがって、脱水動作が進行すると、被洗浄物２に洗浄水を含まない短絡経路ができ、この短絡経路に空気の流れが集中する場合がある。その結果、洗浄水の吸引が進まなくなる。しかしながら、本実施の形態では、被洗浄物２は、押圧部８ａ、８ｂにより膜体４１を介して常時一定の圧力で均一に加圧されているため、短絡風路ができることが抑制される。その結果、洗浄槽４の内部に導入される外気とともに、洗浄水の吸引脱水が停滞することなく進行する。 Here, when the cleaning water and the air inside the cleaning tank 4 are sucked, they pass through the path having the least resistance. Therefore, when the dehydration operation proceeds, a short-circuit path not containing the cleaning water is formed in the article 2 to be cleaned, and the air flow may concentrate on the short-circuit path. As a result, the suction of the washing water does not proceed. However, in the present embodiment, since the object to be cleaned 2 is constantly and uniformly pressed at a constant pressure through the film body 41 by the pressing portions 8a and 8b, the occurrence of a short-circuit air path is suppressed. As a result, the suction and dehydration of the cleaning water proceeds without stagnation, together with the outside air introduced into the cleaning tank 4.
　このようにして、吸引ポンプ２７により押圧部８を膨張させることができる。そして膜体４１には、洗浄槽４の側壁部４ｂの傾斜部の上方に変形吸収部４５が設けられている。これにより、変形吸収部４５は、押圧部８の進退する方向へ伸縮するように形状変化し、押圧部８の動きに無理なく追従することができる。また、被洗浄物２と接触する膜体４１の面は平滑に構成されている。したがって、膜体４１を介して押圧部８の押圧面８０を被洗浄物２に密着させて均一に押圧することができる。これにより、被洗浄物２の内部に外気が導入されて所定の脱水性能を得ることができる。 押 圧 Thus, the pressing part 8 can be expanded by the suction pump 27. The film body 41 is provided with a deformation absorbing portion 45 above the inclined portion of the side wall portion 4b of the cleaning tank 4. Thereby, the deformation absorbing portion 45 changes its shape so as to expand and contract in the direction in which the pressing portion 8 moves forward and backward, and can follow the movement of the pressing portion 8 without difficulty. In addition, the surface of the film body 41 that is in contact with the object to be cleaned 2 is configured to be smooth. Therefore, the pressing surface 80 of the pressing portion 8 can be brought into close contact with the object 2 to be cleaned via the film body 41 and pressed uniformly. Thereby, outside air is introduced into the inside of the article to be cleaned 2 and a predetermined dehydration performance can be obtained.
　なお、脱水ステップ中に、気液分離部３０に設定量を超えて洗浄水が溜まる場合がある。制御部３９は、溢水検知部３８によりこれを検知すると、吸引ポンプ２７の駆動を停止する。その後、脱水排水弁３６を開いて、気液分離部３０に溜まった洗浄水を洗濯機１の外部に排水する。そして、制御部３９は、洗浄水が排水された後、脱水排水弁３６を再び閉じて、吸引ポンプ２７を駆動する。これにより、制御部３９は、洗浄槽４に導入された外気とともに洗浄水を吸引する。 While the dehydration step, the washing water may be accumulated in the gas-liquid separation unit 30 in an amount exceeding a set amount. The controller 39 stops driving the suction pump 27 when the overflow detector 38 detects this. Thereafter, the dewatering drain valve 36 is opened, and the washing water collected in the gas-liquid separation unit 30 is drained to the outside of the washing machine 1. Then, after the washing water is drained, the control unit 39 closes the dewatering drain valve 36 again and drives the suction pump 27. Thereby, the control unit 39 sucks the cleaning water together with the outside air introduced into the cleaning tank 4.
　制御部３９は、上記の吸引が所定時間Ｔ２（例えば、４分）経過すると、開閉弁１１を開く。さらに、制御部３９は、加圧ポンプ１０および吸引ポンプ２７の駆動を停止する。 (4) After a predetermined time T2 (for example, 4 minutes) has elapsed from the suction, the control unit 39 opens the on-off valve 11. Further, the control unit 39 stops driving of the pressurizing pump 10 and the suction pump 27.
　これによって、押圧部８内の空気は開閉弁１１から排出され、洗浄槽４内部の圧力は大気圧に戻る。被洗浄物２は、押圧部８による押圧が解除されて脱水ステップが終了する。 (4) Thereby, the air in the pressing portion 8 is discharged from the on-off valve 11, and the pressure in the cleaning tank 4 returns to the atmospheric pressure. Pressing of the object to be cleaned 2 by the pressing unit 8 is released, and the dehydration step ends.
　上記一連の動作により、脱水ステップが終わると、制御部３９は、気液分離部３０に溜まった洗浄水を、脱水排水経路３７を通して排出し、洗濯コースを終了する。 When the dehydration step is completed by the above series of operations, the control unit 39 drains the washing water accumulated in the gas-liquid separation unit 30 through the dehydration drainage channel 37, and ends the washing course.
　なお、上記の最終脱水動作は中間脱水動作と同様の動作である。ここで、中間脱水動作には、すすぎステップにて行われる中間脱水動作、および、複数回繰り返し実行するすすぎステップ間で行われる中間脱水動作を含む。なお、所定時間Ｔ１、Ｔ２は、各々の中間脱水動作においても最適に設定される。 The above final dehydration operation is the same operation as the intermediate dehydration operation. Here, the intermediate dehydration operation includes an intermediate dehydration operation performed in a rinsing step and an intermediate dehydration operation performed between rinsing steps that are repeatedly performed a plurality of times. Note that the predetermined times T1 and T2 are set optimally also in each of the intermediate dehydrating operations.
　脱水ステップが終了すると、使用者により蓋体５が開かれ、被洗浄物２は洗浄槽４から取り出される。なお、洗濯が行われていない非使用時には、蓋体５を開いた状態に保持できるように構成されている。この状態で使用者は、伸長設定部を操作し、押圧部８を伸長させて膜体４１を伸張させた状態に保持する。これにより、膜体４１は押圧部８により押圧された安定した状態となる。使用者は、膜体４１に付着した水滴や汚れを容易に拭き取ることができる。これにより、被洗浄物２に押圧を作用させる膜体４１を清潔に保つことができる。 (4) When the spin-drying step is completed, the lid 5 is opened by the user, and the object to be cleaned 2 is taken out of the cleaning tank 4. In addition, the cover 5 is configured to be able to be held in an open state when not being used when washing is not performed. In this state, the user operates the extension setting section to extend the pressing section 8 and hold the membrane body 41 in an extended state. Thereby, the film body 41 is brought into a stable state pressed by the pressing portion 8. The user can easily wipe off water droplets and dirt attached to the film body 41. Thereby, the film body 41 that applies a pressure to the article to be cleaned 2 can be kept clean.
　また、加圧ポンプ１０ａ、１０ｂの両方を駆動して押圧部８ａ、８ｂの内部に空気を供給し、押圧部８ａ、８ｂの両方を伸長させる。その結果、膜体４１が伸張して変形吸収部４５が延伸することにより、膜体４１を安定状態に押し出すことができる。これにより、使用者は、膜体４１に付着した汚れ等を容易に拭き取ることができる。 駆 動 Further, both the pressurizing pumps 10a and 10b are driven to supply air into the pressing portions 8a and 8b, and both the pressing portions 8a and 8b are extended. As a result, the film body 41 is expanded and the deformation absorbing section 45 is expanded, so that the film body 41 can be pushed out to a stable state. Thereby, the user can easily wipe off dirt and the like attached to the film body 41.
　なお、本実施の形態では、加圧減圧部７は、可撓性を有する押圧部８と、押圧部８の内部に空気を供給して膨張させる加圧ポンプ１０と、押圧部８の内部の空気を排出して収縮させる開閉弁１１とで構成されている。しかし、これに限られるものではなく、例えば、押圧部８を収縮させるための減圧が開閉弁１１に代えて減圧ポンプ（図示せず）により行われてもよい。また、加圧ポンプ１０が逆転されて減圧ポンプとして利用されてもよい。 In the present embodiment, the pressurizing and depressurizing unit 7 includes a pressing unit 8 having flexibility, a pressurizing pump 10 for supplying air to the inside of the pressing unit 8 to expand, and an inside of the pressing unit 8. And an on-off valve 11 for discharging and contracting air. However, the present invention is not limited to this. For example, decompression for contracting the pressing portion 8 may be performed by a decompression pump (not shown) instead of the on-off valve 11. Further, the pressurizing pump 10 may be reversed and used as a pressure reducing pump.
　なお、本実施の形態では、押圧部８の内部に供給されて押圧部８を膨張させる流体を空気としたが、これに限られるものではなく、その他の気体でも液体でもよい。気体の場合は、本実施の形態のように周囲の空気を加圧ポンプ等で吸気すればよく、排気するときも制約が少なくて都合がよい。一方、液体の場合は、水または水溶液またはオイルなどを使用することができる。さらに、液体を溜める貯留部があると望ましい。液体は、空気より密度が高く気体のように弾性が大きくないため、押圧部８を確実に膨張させることができる。 In the present embodiment, the fluid supplied to the inside of the pressing portion 8 to expand the pressing portion 8 is air. However, the fluid is not limited to this, and may be another gas or liquid. In the case of gas, the surrounding air may be sucked in by a pressurizing pump or the like as in the present embodiment. On the other hand, in the case of a liquid, water, an aqueous solution, oil, or the like can be used. Further, it is desirable to have a storage section for storing the liquid. Since the liquid has a higher density than air and does not have a large elasticity like a gas, the pressing portion 8 can be reliably expanded.
　以上のように、本実施の形態１の洗濯機１は、被洗浄物２と洗浄水とを収容する洗浄槽４と、洗浄槽４の開口部３を開閉する蓋体５と、蓋体５に設けられ、伸縮自在な押圧部８と、押圧部８を覆う膜体４１と、洗浄槽４に収容された被洗浄物２に対して押圧部８を進退させる加圧減圧部７と、加圧減圧部７を制御する制御部３９とを備え、膜体４１は、可撓性を有する材料で構成され、膜体４１には押圧部８の被洗浄物２に対する進退に追従可能に変形する変形吸収部４５を設けたものである。 As described above, the washing machine 1 according to the first embodiment includes the cleaning tank 4 that stores the object to be cleaned 2 and the cleaning water, the lid 5 that opens and closes the opening 3 of the cleaning tank 4, and the lid 5. A pressurizing unit 8 that is provided at the front and rear, a film body 41 that covers the pressurizing unit 8, a pressurizing and depressurizing unit 7 that moves the pressing unit 8 back and forth with respect to the cleaning target 2 stored in the cleaning tank 4, And a control unit 39 for controlling the pressure reducing unit 7. The film body 41 is made of a flexible material, and the film body 41 is deformed so as to follow the advance and retreat of the pressing unit 8 with respect to the object 2 to be cleaned. This is provided with a deformation absorbing portion 45.
　この構成により、押圧部８は膜体４１で覆われ、蛇腹状の伸縮部８ｄが洗浄槽４に対して露出することなく、押圧部８を保護することができる。したがって、洗浄水に含まれる洗剤成分、または被洗浄物２から洗い落とされた汚れ等が押圧部８に付着することなく、清潔に保つことができる。また、押圧部８の動きに膜体４１の変形吸収部４５が応動し、押圧部８の進退動作に膜体４１が無理なく追従して被洗浄物２に押圧力を作用させることができる。また、膜体４１が押圧部８の動きに追従するときの抵抗を少なくすることができ、押圧部８の伸縮動作を行う加圧減圧部７にかかる負荷を低く抑えることができる。 With this configuration, the pressing portion 8 is covered with the film body 41, and the pressing portion 8 can be protected without the bellows-like elastic portion 8 d being exposed to the cleaning tank 4. Therefore, it is possible to keep the detergent component contained in the washing water or the dirt and the like washed off from the article 2 to be kept clean without adhering to the pressing portion 8.
