Description

本発明は、ドラム式洗濯機の洗剤供給装置に関するものである。   The present invention relates to a detergent supply device for a drum-type washing machine.

従来、この種のドラム式洗濯機の洗剤供給装置においては、給水の圧力の高低により洗剤の泡発生が増大することを防止する為に、供給される洗濯水の圧力を一定にすることが提案されている(例えば、特許文献1参照)。   Conventionally, in this type of washing machine for drum type washing machines, it has been proposed to keep the pressure of the supplied wash water constant in order to prevent the generation of detergent foam due to the high and low water supply pressure. (For example, refer to Patent Document 1).

図6は、特許文献1に記載された従来のドラム式洗濯機の構成を示した分解斜視図であり、図7は、同ドラム式洗濯機の洗剤供給装置の流路構成を示した平面図である。   FIG. 6 is an exploded perspective view showing a configuration of a conventional drum type washing machine described in Patent Document 1, and FIG. 7 is a plan view showing a flow path configuration of a detergent supply device of the drum type washing machine. It is.

図6に示すように、洗濯水を収容するために本体10の内部に設置された円筒状の水槽11と、この水槽11の内部に回転自在に設置され、壁面に複数個の脱水孔が形成された円筒状の洗濯槽(回転ドラム)12とを備えている。水槽11の下部には、洗濯、すすぎおよび脱水動作を行うために洗濯槽(回転ドラム)12を正方向または逆方向に回転する駆動モータ13が設置される。   As shown in FIG. 6, a cylindrical water tank 11 installed inside the main body 10 for containing washing water, and a water tank 11 is rotatably installed inside the water tank 11, and a plurality of dewatering holes are formed on the wall surface. And a cylindrical washing tub (rotary drum) 12. A drive motor 13 that rotates the washing tub (rotating drum) 12 in the forward direction or the reverse direction is installed below the water tub 11 in order to perform washing, rinsing, and dewatering operations.

水槽11の上部には、この水槽11の内部に洗濯水を供給するとともに、給水行程で洗剤を供給するものとして、給水装置20および洗剤供給装置15がそれぞれ設置される。   A water supply device 20 and a detergent supply device 15 are installed on the upper portion of the water tank 11 as washing water is supplied into the water tank 11 and detergent is supplied in the water supply process.

給水装置20は、外部の給水ホース(図示せず)に連結されて給水を制御する複数個の給水バルブ21と、これら給水バルブ21と洗剤供給装置15との間を連結する複数個の給水管23と、この洗剤供給装置15を通過した水を水槽11の内部に案内する連結管24等で構成される。   The water supply device 20 is connected to an external water supply hose (not shown) to control water supply, and a plurality of water supply pipes connecting the water supply valve 21 and the detergent supply device 15. And a connecting pipe 24 that guides the water that has passed through the detergent supply device 15 into the water tank 11.

洗剤供給装置15は、前面に開放された開口部34が形成された箱状のハウジング30と、このハウジング30の開口部34を通して、ハウジング30の内部に着脱自在に結合される洗剤ケース35とを含む。また、この洗剤供給装置15は、本体10の外部で洗剤ケース35を引き出しのように着脱するために、本体10の上側前面部に設置される。   The detergent supply device 15 includes a box-shaped housing 30 having an opening 34 opened on the front surface, and a detergent case 35 detachably coupled to the inside of the housing 30 through the opening 34 of the housing 30. Including. The detergent supply device 15 is installed on the upper front portion of the main body 10 in order to attach and detach the detergent case 35 like a drawer outside the main body 10.

図7の洗剤供給装置の流路構成を示した平面図において、すすぎ剤投入部給水流路45に圧力調節孔45aが形成されるので、すすぎ剤投入部給水流路45を通して高圧の洗濯水が流れる場合は、圧力調節孔45aを通して多量の洗濯水が漂白剤投入部35dに抜け出るようになり、低圧の洗濯水が流れる場合は、圧力調節孔45aを通して比較的少量の洗濯水が漂白剤投入部35dに抜け出るようになる。   In the plan view showing the flow path configuration of the detergent supply device of FIG. 7, since the pressure adjusting hole 45 a is formed in the rinse agent charging section water supply flow path 45, high-pressure washing water is passed through the rinse agent charging section water supply path 45. When flowing, a large amount of washing water flows out to the bleach charging portion 35d through the pressure adjusting hole 45a, and when a low pressure washing water flows, a relatively small amount of washing water flows through the pressure adjusting hole 45a. It comes out to 35d.

したがって、すすぎ剤投入部給水部43に到達する洗濯水の圧力は、すすぎ剤投入部給水流路45を通過しながら所定範囲内に調節されるため、すすぎ剤投入部35cに噴射される洗濯水の圧力も、所定範囲内に調節されるもので、高圧力の洗濯水供給により洗剤に泡が発生し、洗剤容器内に泡が充満し、給水が円滑になされず、所定の通路以外から水漏れ等を発生すすることを防止するようになっている。   Accordingly, the pressure of the washing water reaching the rinsing agent charging unit water supply unit 43 is adjusted within a predetermined range while passing through the rinsing agent charging unit water supply channel 45, and therefore the washing water sprayed to the rinsing agent charging unit 35c. The pressure of the water is also adjusted within a predetermined range. Foam is generated in the detergent by supplying high-pressure washing water, the foam is filled in the detergent container, water supply is not smooth, and water is supplied from other than the predetermined passage. It is designed to prevent leakage and the like.

しかしながら、前記従来の構成では、洗濯機外部からのたとえば水道水の給水が所定以上の圧力となり、大流量で給水された場合に効果を発揮するものであり、何らか他の条件で洗剤容器内に洗剤泡が充満した(例えば水槽内で発生した泡が洗剤容器内に逆流した)場合に給水通路が塞がれ、給水が所定通路以外から流れ出ることは防止できない、という課題を有していた。   However, in the conventional configuration, for example, tap water supplied from the outside of the washing machine is at a pressure higher than a predetermined pressure, and is effective when supplied at a large flow rate. When the detergent foam is filled (for example, the foam generated in the water tank flows back into the detergent container), the water supply passage is blocked, and it is impossible to prevent the water supply from flowing out of the predetermined passage. .

特に、回転ドラムの回転攪拌に加えて、近年洗濯効果の向上のため、また、洗濯水の有効活用のため、洗濯水をポンプで循環させて衣類に振りかける循環水流の方式が多用されているが、この方式は多量の洗剤泡を発生する特徴があり、泡の発生により水槽内の圧力が増大し、洗剤容器内に流入するという課題がある。   In particular, in addition to the rotating agitation of the rotating drum, in recent years, in order to improve the washing effect and to effectively use the washing water, a circulating water flow system in which the washing water is circulated by a pump and sprinkled on the clothes is often used. This method is characterized by generating a large amount of detergent foam, and there is a problem that the pressure in the water tank increases due to the generation of foam and flows into the detergent container.

本発明は、上記従来の課題を解決するもので、水槽内で発生した洗剤泡が洗剤供給装置内に逆流した場合に、この洗剤泡を希釈して不具合の発生を防止する構成を提供することを目的としている。   The present invention solves the above-mentioned conventional problems, and provides a configuration in which, when detergent bubbles generated in a water tank flow back into a detergent supply device, the detergent bubbles are diluted to prevent occurrence of problems. It is an object.

前記従来の課題を解決する為に、複数個の脱水孔を形成した回転ドラムを回転自在に軸支する水槽と、前記水槽に洗剤を含む洗濯水を供給する洗剤供給装置と、前記水槽と前記洗剤供給装置とを接続配管するとともに逆流防止手段を備えた給水連結管と、前記洗剤供給装置に給水する第1の給水弁と、前記第1の給水弁からの給水を導く第1の給水通路と、前記洗剤供給装置に構成した水槽空気抜き接続部と前記水槽とを接続配管した水槽空気抜き管と、洗濯、すすぎ、脱水等一連の行程を制御する制御装置とを備え、前記洗剤供給装置は、前記第1の給水通路と前記水槽空気抜き接続部とを連通させたものである。   In order to solve the conventional problems, a water tank that rotatably supports a rotating drum having a plurality of dewatering holes, a detergent supply device that supplies washing water containing detergent to the water tank, the water tank, and the water tank A water supply connecting pipe that is connected to the detergent supply device and includes a backflow prevention means, a first water supply valve that supplies water to the detergent supply device, and a first water supply passage that guides water supplied from the first water supply valve A water tank air vent pipe connecting the water tank air vent connecting part and the water tank configured in the detergent supply device, and a control device for controlling a series of processes such as washing, rinsing and dehydration, The first water supply passage and the water tank air vent connection portion are communicated with each other.

これにより、第1の給水弁を制御して、水槽空気抜き管内部を常時洗剤泡の消泡と堆積を防止することにより、水槽の内部に洗剤泡が発生した場合でも、水槽内の圧力が高まりにくくなり、給水時あるいは洗剤供給時に供給する水が所定の通路以外から流れ出たり、洗剤供給装置よりあふれ出るという不具合の発生が防止できる。   Thereby, even if a detergent bubble generate | occur | produces in the inside of a water tank by controlling a 1st water supply valve and preventing defoaming and accumulation | storage of a detergent foam inside a water tank air vent pipe, the pressure in a water tank increases. It becomes difficult to prevent the occurrence of a problem that the water supplied at the time of water supply or detergent supply flows out of a predetermined passage or overflows from the detergent supply device.

本発明のドラム式洗濯機は、水槽内より洗剤供給装置内に逆流した洗剤泡を希釈し、水漏れ等の不具合の発生を防止することができる。   The drum type washing machine of the present invention can dilute the detergent bubbles that have flowed back from the water tank into the detergent supply device, and prevent the occurrence of problems such as water leakage.

FIG. 4 is a control circuit block diagram of the drum type washing machine, and FIG. 5 is a stroke operation table of the drum type washing machine.

図1において、前面に開閉自在に蓋体62を構成したドラム式洗濯機の本体50の内部には、洗濯水を収容するために設置された円筒状の水槽51と、この水槽51の内部に回転自在に設置され、壁面に複数個の脱水孔52が形成された円筒状の回転ドラム53とを備える。   In FIG. 1, a drum-type washing machine main body 50 having a lid 62 configured to be openable and closable on the front surface includes a cylindrical water tank 51 installed to store washing water, and the water tank 51. A cylindrical rotating drum 53 that is rotatably installed and has a plurality of dewatering holes 52 formed on the wall surface is provided.

前記水槽51の上部には、この水槽51の内部に洗濯水を供給するとともに、洗剤を供給するものとして、予洗い用給水弁(第1の給水弁)54、本洗い用給水弁(第2の給水弁)55および洗剤供給装置56がそれぞれ設置される。   In the upper part of the water tank 51, washing water is supplied to the inside of the water tank 51, and a detergent is supplied. A water supply valve for pre-washing (first water supply valve) 54, a water supply valve for main washing (second water supply valve) The water supply valve) 55 and the detergent supply device 56 are respectively installed.

水槽51の下部には、洗濯、すすぎおよび脱水動作を行うために水槽51内部の回転ドラム53を正方向または逆方向に回転駆動するモータ57が設置される。   A motor 57 that rotationally drives the rotating drum 53 in the water tank 51 in the forward direction or the reverse direction is installed below the water tank 51 in order to perform washing, rinsing, and dewatering operations.

予洗い用給水弁54、および本洗い用給水弁55は、機外側で外部の給水ホース58に連結され、機内側で洗剤供給装置56との間を連結する複数個の給水管59a、59bで配管される。前記洗剤供給装置56は、通過した水を水槽51の内部に案内する給水連結管60および、洗剤や柔軟剤、仕上げ材等を収納するため、本体前方に引き出し可能な洗剤ケース61等で構成される。   The pre-wash water supply valve 54 and the main-wash water supply valve 55 are connected to an external water supply hose 58 on the outside of the machine and a plurality of water supply pipes 59a and 59b connecting the detergent supply device 56 to the inside of the machine. It is plumbed. The detergent supply device 56 includes a water supply connecting pipe 60 that guides the passed water to the inside of the water tank 51, and a detergent case 61 that can be pulled out in front of the main body in order to store detergent, softener, finishing material, and the like. The

給水連結管60には、逆止弁(図示せず)が設けられており、水槽51からの泡や空気、洗濯水が逆流して洗剤供給装置56側に進入しないように逆流防止手段で構成されている。また、逆止弁でなくても一般的なU字トラップで構成し、U字部分に水を常に溜めて、水槽51からの泡や空気、洗濯水が逆流して洗剤供給装置56側に進入しないような逆流防止手段を構成してもよい。   The water supply connection pipe 60 is provided with a check valve (not shown), and is configured with backflow prevention means so that bubbles, air, and washing water from the water tank 51 flow backward and do not enter the detergent supply device 56 side. Has been. Moreover, even if it is not a check valve, it is composed of a general U-shaped trap, and water is always accumulated in the U-shaped part, so that bubbles, air and washing water from the water tank 51 flow backward and enter the detergent supply device 56 side. You may comprise the backflow prevention means which does not.

水槽51内底部には温水洗濯用の加熱ヒータ63を、さらにその下方には、洗濯水の排水用の排水筒64を構成する。前記排水筒64は、排水管65に接続配管され、糸屑や異物除去のフィルター66を通過して排水ポンプ(DP)67から排水吐出ホース68に連通する。この排水ポンプ(DP)67を駆動すれば、水槽内の洗濯水を機外に排出する。   A heater 63 for warm water washing is formed at the bottom of the water tank 51, and a drain pipe 64 for draining the washing water is formed below the heater 63. The drain cylinder 64 is connected to a drain pipe 65, passes through a filter 66 for removing lint and foreign matter, and communicates with a drain discharge hose 68 from a drain pump (DP) 67. If this drain pump (DP) 67 is driven, the washing water in the water tank is discharged out of the machine.

前記フィルター66より吸引管69を配管して洗濯水循環ポンプ(WP)70に連通させ、さらに洗濯水循環ポンプ(WP)70の吐出側に循環水吐出ホース71を介して、蓋体62の近傍内方の吐出口72から回転ドラム53内方を指向する。   A suction pipe 69 is piped from the filter 66 to communicate with a washing water circulation pump (WP) 70, and further inside the vicinity of the lid 62 via a circulation water discharge hose 71 on the discharge side of the washing water circulation pump (WP) 70. From the discharge port 72 toward the inside of the rotary drum 53.

前記洗濯水循環ポンプ(WP)70を駆動すると、回転ドラム53内部の洗濯水は、排水筒64より吸引され、吐出口72から回転ドラム53内方の衣類に衝突させる循環水73を構成し、洗浄効果を向上させている。しかし同時に水槽51内に洗剤泡を発生させるので、水槽51内の内圧が高まることになる。   When the washing water circulation pump (WP) 70 is driven, the washing water inside the rotary drum 53 is sucked from the drain pipe 64 and constitutes the circulating water 73 that collides with the clothes inside the rotary drum 53 from the discharge port 72 to be washed. The effect is improved. However, since detergent bubbles are generated in the water tank 51 at the same time, the internal pressure in the water tank 51 is increased.

本体50内方に取り付けた制御装置49は、前述のモータ57、予洗い用給水弁(第1の給水弁)54、本洗い用給水弁(第2の給水弁)55、排水ポンプ(DP)67、洗濯水循環ポンプ(WP)70等を制御して、洗濯、すすぎ、脱水等の一連の行程を制御し、入力設定手段や表示手段(図示せず)を有する。   The control device 49 attached to the inside of the main body 50 includes the motor 57, the pre-washing water supply valve (first water supply valve) 54, the main washing water supply valve (second water supply valve) 55, and the drainage pump (DP). 67, a washing water circulation pump (WP) 70 and the like are controlled to control a series of steps such as washing, rinsing and dehydration, and input setting means and display means (not shown) are provided.

また、本願のドラム式洗濯機では、洗濯性能向上のため、洗濯行程を予洗い行程と本洗い行程との2工程で制御するが、その行程とも、前記洗濯水循環ポンプ(WP)70を常時あるいは所定時間駆動させる制御を有する(詳細後述)。   In the drum type washing machine of the present application, the washing process is controlled in two steps, the pre-washing process and the main washing process, in order to improve the washing performance. In both processes, the washing water circulation pump (WP) 70 is always or It has control to drive for a predetermined time (details will be described later).

水槽51の上部には、可撓性ホースで構成した水槽空気抜き管74を配し、洗剤供給装置56の上部に接続する。これは、予洗い行程などで水槽51内部が洗剤等で発生した泡の内圧が増大すると、本洗い行程で洗剤供給装置56から洗剤や給水が円滑に水槽内に供給できなくなることを防止するために、水槽内部を減圧させることを目的として構成されている。   In the upper part of the water tank 51, a water tank air vent pipe 74 constituted by a flexible hose is arranged and connected to the upper part of the detergent supply device 56. This is to prevent the detergent and water supply from being smoothly supplied from the detergent supply device 56 to the water tank in the main washing process when the internal pressure of the foam generated in the water tank 51 by the detergent or the like increases in the pre-washing process or the like. In addition, it is configured for the purpose of reducing the pressure inside the water tank.

While flowing in, it falls widely downward from the water injection port 78, and the prewash detergent previously introduced from the prewash detergent storage part 81 of the detergent case 61 described in FIG. 2 is washed away and supplied to the water tank.

予洗い行程終了後、本洗い行程の開始時には本洗い用給水弁(第2の給水弁)55を動作させると、本洗い給水吐出筒94より吐出し本洗い洗剤用給水通路(第2の給水通路)から給水された洗濯水は、点線矢印Bに示すように通路を前方に流れ、図で左側の迂回絽88で左右にUターン分離し、多数の注水口78をそれぞれ形成した左通路90、右通路89に流れ込みつつ注水口78から下方に幅広く落下し、図2で説明した洗剤ケース61の本洗い用洗剤収納部80より予め投入しておいた本洗い用洗剤を押し流し水槽に供給する。   When the main washing water supply valve (second water supply valve) 55 is operated at the start of the main washing process after the prewashing process, the main washing detergent water supply passage (second water supply) is discharged from the main washing water supply discharge cylinder 94. The washing water supplied from the passageway) flows forward through the passage as indicated by a dotted arrow B, and is divided into U-turns to the left and right by a detour bar 88 on the left side in the figure, and a left passage 90 having a plurality of water injection ports 78 formed respectively. Then, while flowing into the right passage 89, it falls widely downward from the water inlet 78, and the main washing detergent previously introduced from the main washing detergent storage portion 80 of the detergent case 61 described in FIG. 2 is washed away and supplied to the water tank. .

予洗い行程用の洗濯水の流れAの一部は左通路86を流れ、上部ケース76の図で右端に接続した水槽空気抜き管74の水槽空気抜き接続部91に矢印Cの状態で到達し、一部は水槽空気抜き管74内に流入するように、予洗い洗剤用給水通路の左通路86と、水槽空気抜き接続部91とを連通させた構成としている。   Part of the washing water flow A for the pre-washing process flows in the left passage 86 and reaches the water tank air vent connection portion 91 of the water tank air vent pipe 74 connected to the right end in the figure of the upper case 76 in the state of arrow C. The portion is configured such that the left passage 86 of the prewash detergent water supply passage and the water tank air vent connection portion 91 communicate with each other so as to flow into the water tank air vent pipe 74.

図4の制御回路図において、制御装置49は、入力設定手段48より設定された制御内容をマイクロプロセッサー等で構成された制御手段47により、モータ57、予洗い用給水弁(第1の給水弁)54、洗濯水循環ポンプ(WP)70等の負荷をパワースイッチ手段46を介して制御し、洗濯、すすぎ、脱水等の一連の行程を制御する。   In the control circuit diagram of FIG. 4, the control device 49 uses the control means 47 configured by a microprocessor or the like to control the contents set by the input setting means 48, and the motor 57, the pre-wash water supply valve (first water supply valve). ) 54, the load such as the washing water circulation pump (WP) 70 is controlled through the power switch means 46, and a series of processes such as washing, rinsing and dehydration are controlled.

以上のように構成した洗濯機について、図5の行程動作図に従ってその動作、作用を説明する。   About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated according to the stroke operation | movement figure of FIG.

ドラム式洗濯機の運転を開始すると、まず予洗い行程(101)が開始され、予洗い用給水弁(第1の給水弁)54の動作で給水と共に予洗い行程用洗剤が水槽内に供給され(103)、回転ドラム53を正方向または逆方向に回動する攪拌(104)することで洗い作業が進行するが、このとき洗濯水循環ポンプ(WP)70も駆動させ(105)、洗濯循環水流にて衣類に洗濯液を循環水73を振りかけ、洗濯効果を高める。   When the operation of the drum type washing machine is started, the pre-washing process (101) is first started, and the pre-washing detergent is supplied into the water tank together with the water by the operation of the pre-washing water supply valve (first water supply valve) 54. (103) The washing operation proceeds by stirring (104) rotating the rotating drum 53 in the forward or reverse direction. At this time, the washing water circulation pump (WP) 70 is also driven (105), and the washing circulation water flow Sprinkle the washing liquid on the clothes with circulating water 73 to enhance the washing effect.

このとき、洗濯循環水流により、水槽51内に泡が多量に発生することがある。その際水槽51内部は圧力が高まると、次行程の本洗い行程(102)の開始時には本洗い用給水弁(第2の給水弁)55を動作させた(107)場合に、本洗い洗剤用給水通路(第2の給水通路)84から給水された洗濯水、ならびに本洗い用洗剤は下部ケース77及び水槽51への給水連結管60へ円滑に流れず、洗剤ケース61の前方から溢れ出ようとする。   At this time, a large amount of foam may be generated in the water tank 51 due to the washing circulation water flow. At that time, when the pressure in the water tank 51 is increased, the main washing water supply valve (second water supply valve) 55 is operated (107) at the start of the main washing process (102) of the next process. The washing water supplied from the water supply passage (second water supply passage) 84 and the main washing detergent do not flow smoothly into the lower case 77 and the water supply connection pipe 60 to the water tank 51, and will overflow from the front of the detergent case 61. And

その防止のため、水槽内の圧力緩和のため水槽空気抜き管74にて水槽内を減圧するものであるが、洗剤泡の発生が多量になれば、前記給水連結管60並びに前記水槽空気抜き管74内に泡が侵入することがある。   In order to prevent this, the water tank is depressurized by the water tank air vent pipe 74 to relieve the pressure in the water tank. If a large amount of detergent bubbles are generated, the water supply connection pipe 60 and the water tank air vent pipe 74 are Bubbles may enter the surface.

そこで、予洗い行程中(101)、予洗い用洗剤を供給完了した後も予洗い用給水弁(第1の給水弁)54を連続または所定時間動作を継続させて(106)、図3で示した水の流れ矢印Cにて、水槽空気抜き接続部91および水槽空気抜き管74内の洗剤泡を希釈ならびに消泡し、洗剤供給装置56内に洗剤泡の侵入や発生の防止と、水槽51内部の圧力上昇を防止する。   Therefore, during the pre-washing process (101), even after the pre-washing detergent has been supplied, the pre-washing water supply valve (first water supply valve) 54 is operated continuously or for a predetermined time (106). In the water flow arrow C shown, the detergent bubbles in the aquarium air vent connection portion 91 and the aquarium air vent pipe 74 are diluted and defoamed to prevent the detergent bubbles from entering and generating in the detergent supply device 56, and the inside of the aquarium 51. To prevent pressure rise.

よって、次行程の本洗い行程(102)の給水動作(107)において、給水された洗濯水および本洗い用洗剤液が洗剤ケース外にあふれることはない。   Therefore, in the water supply operation (107) of the main washing process (102) of the next process, the supplied washing water and the main washing detergent liquid do not overflow outside the detergent case.

さらに、本洗い行程(102)においては、本洗い用給水弁(第2の給水弁)55で本洗い洗剤を供給し(107)、回転ドラム53の攪拌(112)ならびに洗濯水循環ポンプ(WP)70の駆動による洗濯循環水流の動作中(109)にも、予洗い用給水弁(第1の給水弁)54を連続または所定時間動作を継続させて(108)、水槽空気抜き管74の洗剤泡を希釈ならびに消泡し、水槽空気抜き管74内への洗剤泡の堆積を防止する。   Further, in the main washing step (102), the main washing detergent is supplied by the main washing water supply valve (second water supply valve) 55 (107), the rotating drum 53 is agitated (112) and the washing water circulation pump (WP). Even during the operation of the washing circulation water flow by driving 70 (109), the pre-wash water supply valve (first water supply valve) 54 is operated continuously or for a predetermined time (108), so that the detergent bubbles in the water tank air vent pipe 74 are removed. Is diluted and defoamed to prevent detergent foam from accumulating in the water tank bleed tube 74.

よって、次行程のすすぎ行程(111)において、すすぎ水の給水動作(110)がなされた場合に、給水されたすすぎ水が洗剤ケース外にあふれることはない。   Therefore, when the rinse water supply operation (110) is performed in the rinse process (111) of the next process, the supplied rinse water does not overflow outside the detergent case.

以上のように、予洗い用の給水弁を活用して、水槽空気抜き管内部を、常時洗剤泡の消泡と堆積を防止することにより、水槽の内部に洗剤泡が発生した場合でも、水槽内の圧力が高まりにくくなり、給水時あるいは洗剤供給時に供給する水が所定通路以外から流れ出たり、洗剤ケース部よりあふれ出るという不具合の発生が防止できる。   As mentioned above, even if detergent bubbles are generated inside the aquarium by preventing the defoaming and accumulation of detergent bubbles at all times by utilizing the water valve for pre-washing, It is difficult to increase the pressure of the water, and it is possible to prevent a problem that water supplied at the time of water supply or detergent supply flows out of a predetermined passage or overflows from the detergent case.

以上のように、本発明にかかるドラム式洗濯機は、予洗い用の給水弁を活用して、水槽空気抜き管内部を、常時洗剤泡の消泡と堆積を防止することが可能となるので、複数の給水弁を有する機器、ドラム式洗濯機以外の洗濯機等の用途にも適用できる。   As described above, the drum-type washing machine according to the present invention can prevent defoaming and accumulation of detergent bubbles at all times inside the aquarium air vent pipe by utilizing a pre-feed water supply valve. The present invention can also be applied to uses such as equipment having a plurality of water supply valves and washing machines other than drum type washing machines.
