It is arranged substantially above 20a.

なお、流体バランサ20の柔軟剤自動流出装置21が配置される部分には、図7に示すように柔軟剤投入口22が設けられているので、使用者は柔軟剤を、柔軟剤投入口22から柔軟剤自動流出装置21に投入することができる。   In addition, since the softener inlet 22 is provided in the part by which the softener automatic outflow apparatus 21 of the fluid balancer 20 is arrange | positioned, as shown in FIG. To the softener automatic efflux device 21.

上記構成において動作を説明すると、使用者が洗濯したい被洗浄物23を洗濯兼脱水槽4に洗剤とともに投入し、スタートボタン(図示しない)を押すことで、給水弁16から所定量の洗濯水が水槽3に供給される。洗濯水が供給されると、Vベルト8および減速機構9を介して駆動手段7により、パルセータ5が所定の回転数で回転して、洗濯兼脱水槽4内の洗濯水および被洗浄物23を攪拌して、被洗浄物23から汚れを落とす洗い行程が行われる。   The operation in the above configuration will be described. The object to be washed 23 that the user wants to wash is put into the washing and dewatering tub 4 together with the detergent, and a start button (not shown) is pushed, so that a predetermined amount of washing water is supplied from the water supply valve 16. It is supplied to the water tank 3. When the washing water is supplied, the pulsator 5 is rotated at a predetermined rotational speed by the driving means 7 via the V-belt 8 and the speed reduction mechanism 9, and the washing water and the object to be cleaned 23 in the washing and dewatering tub 4 are removed. A washing process of stirring and removing dirt from the object to be cleaned 23 is performed.

所定時間の洗い行程が終了すると、排水弁15が動作して水槽3内の洗濯水を排水し、排水が終わると、Vベルト8および減速機構9を介して駆動手段7により、洗濯兼脱水槽4が所定の回転数で回転して、被洗浄物23から洗濯水を分離して排水する脱水行程が行われる。   When the washing process for a predetermined time is completed, the drain valve 15 is operated to drain the washing water in the water tub 3, and when the drainage is finished, the washing and dewatering tub is driven by the driving means 7 via the V belt 8 and the speed reduction mechanism 9. 4 rotates at a predetermined rotational speed, and a dehydration process is performed in which the washing water is separated from the article to be cleaned 23 and drained.

脱水行程が所定時間行われると、再び給水弁16から所定量のすすぎ水が水槽3に供給され、パルセータ5が所定の回転数で回転して、洗濯兼脱水槽4内のすすぎ水および被洗浄物23を攪拌して、被洗浄物23に残っている洗剤成分を除去するすすぎ行程が行われる。   When the dehydration process is performed for a predetermined time, a predetermined amount of rinsing water is again supplied from the water supply valve 16 to the water tank 3, and the pulsator 5 rotates at a predetermined number of rotations, so that the rinsing water in the washing and dewatering tank 4 and the object to be cleaned A rinsing process is performed in which the product 23 is stirred to remove the detergent components remaining in the product 23 to be cleaned.

しかしながら、図6〜図10に示されるような従来の洗濯機の構成では、以下のような課題がある。   However, the configuration of the conventional washing machine as shown in FIGS. 6 to 10 has the following problems.

近年の洗濯機に求められるお客様のニーズとして、洗濯機1の外形寸法(高さ方向も含む)を小さく、被洗浄物23を収納できる容量は多くしてほしい、ということがある。   A customer's need for a washing machine in recent years is that the outside dimensions (including the height direction) of the washing machine 1 are small and that the capacity for storing the object to be cleaned 23 is increased.

そのため、図6に示すように、洗濯機1の外径寸法に余裕がある頃の従来の洗濯機1は、洗濯兼脱水槽4の容量を、所定量の被洗浄物23の量よりも大きくすることができたので、洗濯兼脱水槽4に、所定量の被洗浄物23を投入しても、被洗浄物23が洗濯兼脱水槽4からはみ出すのを防止することが可能であったが、近年の洗濯機1は、図8に示すように、洗濯兼脱水槽4の容量を、所定量の被洗浄物23の量とほぼ同等にして、洗濯機1の外形寸法を少しでも小さくするようにしている。   Therefore, as shown in FIG. 6, the conventional washing machine 1 when the outside diameter of the washing machine 1 has a margin has a larger capacity of the washing and dewatering tub 4 than the amount of the object to be cleaned 23. Therefore, even if a predetermined amount of the object to be cleaned 23 is put into the washing and dewatering tub 4, it is possible to prevent the object to be cleaned 23 from protruding from the washing and dewatering tub 4. In recent washing machines 1, as shown in FIG. 8, the capacity of the washing and dewatering tub 4 is made substantially equal to the amount of the object to be cleaned 23, and the outside dimensions of the washing machine 1 are reduced as much as possible. I am doing so.

洗濯兼脱水槽4の容量を、所定量の被洗浄物23の量とほぼ同等にすると、所定量の被洗浄物23を入れた場合、被洗浄物23が洗濯水によって水分を含むことで、被洗浄物23は膨らんでいるので、図8に示すように、洗濯兼脱水槽4から飛び出しそうなぐらいまでになってしまう。   When the capacity of the washing and dewatering tub 4 is made substantially equal to the amount of the object to be cleaned 23, when the object to be cleaned 23 is put in, the object to be cleaned 23 contains moisture by the washing water, Since the object to be cleaned 23 is swelled, as shown in FIG.

被洗浄物23が、洗濯兼脱水槽4から飛び出すのを防止するために、図8に示すように、流体バランサ20の上部にバランサリブ24を設けている。柔軟剤投入口22にも、バランサリブ24を、図9に示すように、柔軟剤投入口22の、洗濯兼脱水槽4の回転中心と反対側に設けることで、被洗浄物23が洗濯兼脱水槽4から飛び出すのを防止することができる。   In order to prevent the object to be cleaned 23 from jumping out of the washing / dehydrating tub 4, a balancer rib 24 is provided on the upper part of the fluid balancer 20, as shown in FIG. As shown in FIG. 9, the balancer rib 24 is also provided at the softener charging port 22 on the side opposite to the rotation center of the washing / dehydrating tub 4 so that the object to be cleaned 23 is washed and removed. Jumping out of the water tank 4 can be prevented.

しかしながら、洗濯機1は、前回の一連の運転が終了した時、洗濯兼脱水槽4は任意の位置で停止するので、流体バランサ20に設けられた柔軟剤自動流出装置21および柔軟剤投入口22は、どの位置に停止しているかは判断できないものである。そのため、図10に示すように、柔軟剤投入口22が給水弁16の給水口16aの近傍に停止していて、流体バランサ20の開口部20a近傍まで乾いた被洗浄物23が洗濯兼脱水槽4内に投入されている状態で運転が開始され、給水口16aから洗濯水が給水されると、被洗浄物23の投入状態によっては、洗濯水の一部が被洗浄物23によって柔軟剤自動流出装置21側に飛び散ってしまい、流体バランサ20の柔軟剤投入口22を介して柔軟剤自動流出装置21内に浸入する場合が生じてしまう。そのため、洗い行程の洗濯水の給水中に、柔軟剤自動流出装置21内にある柔軟剤と洗濯水とが混ざり合って柔軟剤の濃度が低下してしまい、さらには柔軟剤自動流出装置21から柔軟剤が溢れ出してしまって、洗い行程時に所定量の柔軟剤が柔軟剤自動流出装置に蓄えられず、そのために、最終のすすぎ行程で所定量の柔軟剤が洗濯兼脱水槽に投入されずに、柔軟剤による所定の性能を得ることができないという問題が発生してしまう。   However, in the washing machine 1, when the previous series of operations is completed, the washing and dewatering tub 4 stops at an arbitrary position. Therefore, the automatic softener outlet 21 and the softener inlet 22 provided in the fluid balancer 20 are used. Cannot be determined at which position. Therefore, as shown in FIG. 10, the softener charging port 22 is stopped in the vicinity of the water supply port 16a of the water supply valve 16, and the object to be cleaned 23 which is dried to the vicinity of the opening 20a of the fluid balancer 20 is washed and dewatered. 4 is started and the washing water is supplied from the water supply port 16a. Depending on the state of the object to be cleaned 23, a part of the washing water may be automatically softened by the object 23 to be cleaned. It will scatter to the outflow device 21 side and may enter the softener automatic outflow device 21 through the softener inlet 22 of the fluid balancer 20. Therefore, the softener and the washing water in the softener automatic spill device 21 are mixed with each other during the washing water supply in the washing process, and the concentration of the softener is lowered. The softening agent overflows and the predetermined amount of softening agent is not stored in the automatic softener outflow device during the washing process. For this reason, the predetermined amount of softening agent is not put into the washing and dehydrating tank in the final rinsing process. In addition, there arises a problem that a predetermined performance by the softening agent cannot be obtained.

本発明は上記従来の課題を解決するもので、すすぎ行程で柔軟剤による所定の性能を得ることを目的としている。   The present invention solves the above-described conventional problems, and an object thereof is to obtain a predetermined performance by a softening agent in a rinsing process.

前記従来の課題を解決するため、本発明の洗濯機は、本体内に配設し内部に脱水回転可能な洗濯兼脱水槽を有した水槽と、前記洗濯兼脱水槽の底面に回転自在に配設したパルセータと、前記洗濯兼脱水槽の上端部に設けた流体バランサと、前記流体バランサに配置され柔軟剤を最終すすぎ行程開始前に前記水槽内に流出させる柔軟剤自動流出装置と、洗濯、すすぎ、脱水など一連の動作を制御する制御手段と、前記流体バランサに設けられ前記柔軟剤自動流出装置と連通する柔軟剤投入口とを備え、前記流体バランサの略上部にバランサリブを設けると共に、前記バランサリブを前記柔軟剤投入口の周囲に設け、前記柔軟剤投入口の前記洗濯兼脱水槽の回転中心と反対側に設けた前記バランサリブの一部に切り欠き部を設けたものである。 In order to solve the above-described conventional problems, a washing machine of the present invention includes a water tub provided in a main body and having a washing and dewatering tub that can be dewatered and rotated inside, and a bottom surface of the washing and dewatering tub. A pulsator provided, a fluid balancer provided at the upper end of the washing and dewatering tub, a softener automatic spill device arranged in the fluid balancer and allowing the softener to flow into the water tub before the final rinsing process, and washing, Control means for controlling a series of operations such as rinsing and dehydration, and a softener charging port provided in the fluid balancer and communicating with the softener automatic outflow device, and provided with a balancer rib substantially at the top of the fluid balancer , A balancer rib is provided around the softener charging port, and a notch is provided in a part of the balancer rib provided on the softener charging port on the opposite side of the rotation center of the washing / dehydrating tub.

これにより、被洗浄物が、洗濯兼脱水槽から飛び出すのを防止することができるとともに、給水口から洗濯水が給水されるときに、洗濯水の一部が被洗浄物によって柔軟剤自動流出装置側に飛び散って、流体バランサの柔軟剤投入口を介して柔軟剤自動流出装置内に浸入するのを防止することができる。   Thus, the washing object can be prevented from jumping out of the washing and dewatering tank, and when the washing water is supplied from the water supply port, a part of the washing water is automatically discharged by the washing object. It is possible to prevent splashing to the side and entering the softener automatic outlet device through the softener inlet of the fluid balancer.

本発明の洗濯機は、被洗浄物が、洗濯兼脱水槽から飛び出すのを防止することができるとともに、給水口から洗濯水が給水されるときに、洗濯水の一部が被洗浄物によって柔軟剤自動流出装置側に飛び散って、流体バランサの柔軟剤投入口を介して柔軟剤自動流出装置内に浸入するのを防止することができる。   The washing machine of the present invention can prevent the object to be washed from jumping out of the washing and dewatering tank, and when washing water is supplied from the water supply port, a part of the washing water is softened by the object to be washed. It is possible to prevent splashing into the automatic agent outflow device side and entering the softener automatic outflow device via the softener inlet of the fluid balancer.

したがって、洗い行程の洗濯水の給水中に、柔軟剤投入口に洗濯水が浸入しないので、柔軟剤自動流出装置の貯留部内にある柔軟剤と洗濯水とが混ざり合って柔軟剤の濃度が低下することはない。また、柔軟剤自動流出装置の貯留部から柔軟剤が溢れ出して洗い行程時に所定量の柔軟剤が柔軟剤自動流出装置の貯留部に蓄えられずに、最終のすすぎ行程で所定量の柔軟剤が洗濯兼脱水槽に投入できなかったりすることがない。このように、柔軟剤による所定の性能を安定的に得ることができる。   Therefore, since the washing water does not enter the softener inlet when washing water is supplied during the washing process, the softener and washing water in the storage section of the softener automatic spill device mix and the softener concentration decreases. Never do. In addition, the softener overflows from the storage part of the softener automatic spill device, and a predetermined amount of softener is not stored in the storage part of the softener automatic spill device during the washing process. Will not be able to be put into the washing and dewatering tank. Thus, the predetermined performance by the softener can be stably obtained.

第1の発明は、本体内に配設し内部に脱水回転可能な洗濯兼脱水槽を有した水槽と、前記洗濯兼脱水槽の底面に回転自在に配設したパルセータと、前記洗濯兼脱水槽の上端部に設けた流体バランサと、前記流体バランサに配置され柔軟剤を最終すすぎ行程開始前に前記水槽内に流出させる柔軟剤自動流出装置と、洗濯、すすぎ、脱水など一連の動作を制御する制御手段と、前記流体バランサに設けられ前記柔軟剤自動流出装置と連通する柔軟剤投入口とを備え、前記流体バランサの略上部にバランサリブを設けると共に、前記バランサリブを前記柔軟剤投入口の周囲に設け、前記柔軟剤投入口の前記洗濯兼脱水槽の回転中心と反対側に設けた前記バランサリブの一部に切り欠き部を設けたものであり、被洗浄物が、洗濯兼脱水槽から飛び出すのを防止することができるとともに、給水口から洗濯水が給水されるときに、洗濯水の一部が被洗浄物によって柔軟剤自動流出装置側に飛び散って、流体バランサの柔軟剤投入口を介して柔軟剤自動流出装置内に浸入するのを防止することができる。 A first invention includes a water tank having a washing and dewatering tub disposed in a main body and capable of dewatering rotation therein, a pulsator rotatably disposed on a bottom surface of the washing and dewatering tank, and the washing and dewatering tank A fluid balancer provided at the upper end of the fluid, a softener automatic drain device arranged on the fluid balancer to allow the softener to flow into the water tank before the start of the final rinsing process, and a series of operations such as washing, rinsing and dewatering are controlled. A control means, and a softener inlet provided in the fluid balancer and communicating with the softener automatic outflow device. A balancer rib is provided at a substantially upper portion of the fluid balancer, and the balancer rib is disposed around the softener inlet. provided, wherein it is the center of rotation of the washing and dewatering tank softener inlet to that provided partially cutaway portion of the Baransaribu provided on the opposite side, the object to be cleaned is jumping out from the washing and dewatering tank When washing water is supplied from the water supply port, a part of the washing water scatters to the softener automatic spill device side by the object to be cleaned and passes through the softener inlet of the fluid balancer. It is possible to prevent entry into the softener automatic spill device.

したがって、洗い行程の洗濯水の給水中に、柔軟剤投入口に洗濯水が浸入しないので、柔軟剤自動流出装置の貯留部内にある柔軟剤と洗濯水とが混ざり合って柔軟剤の濃度が低下することはない。また、柔軟剤自動流出装置の貯留部から柔軟剤が溢れ出して洗い行程時に所定量の柔軟剤が柔軟剤自動流出装置の貯留部に蓄えられずに、最終のすすぎ行程で所定量の柔軟剤が洗濯兼脱水槽に投入できなかったりすることがない。このように、柔軟剤による所定の性能を安定的に得ることができる。   Therefore, since the washing water does not enter the softener inlet when washing water is supplied during the washing process, the softener and washing water in the storage section of the softener automatic spill device mix and the softener concentration decreases. Never do. In addition, the softener overflows from the storage part of the softener automatic spill device, and a predetermined amount of softener is not stored in the storage part of the softener automatic spill device during the washing process. Will not be able to be put into the washing and dewatering tank. Thus, the predetermined performance by the softener can be stably obtained.

また、バランサリブを前記柔軟剤投入口の周囲に設けることにより、バランサリブにより、柔軟剤をどの範囲に投入すれば柔軟剤自動流出装置内に確実に供給できるかを明確にすることができるので、使用者は、柔軟剤を柔軟剤投入口に投入しやすくなり、所定量の柔軟剤を柔軟剤自動流出装置の貯留部に供給することができ、最終のすすぎ行程で所定量の柔軟剤を洗濯兼脱水槽に投入し、柔軟剤による所定の性能を安定的に得ることができる。 In addition, by providing a balancer rib around the softener charging port, it is possible to clarify which range the softener can be fed into the automatic softener outflow device with the balancer rib. The person can easily put the softener into the softener inlet, and can supply a predetermined amount of the softener to the storage portion of the softener automatic spill device. A predetermined performance by the softening agent can be stably obtained by putting it in the dehydration tank.

さらに、前記柔軟剤投入口の前記洗濯兼脱水槽の回転中心と反対側に設けた前記バランサリブの一部に切り欠き部を設けることにより、柔軟剤は、柔軟剤投入口から溢れ出てきても、切り欠き部から、流体バランサと水槽との隙間に流れていき、水槽の底部に流れていくようにすることができる。これにより、例えば、第一の脱水行程中に柔軟剤自動流出装置21から柔軟剤が逆流して柔軟剤投入口22から溢れ出てきたような場合でも、洗濯兼脱水槽4の遠心力により、逆流して出てきた柔軟剤は、バランサリブ24の切り欠き部24aから水槽3に向かって流れていくので、柔軟剤が、柔軟剤投入口22およびバランサリブ24の上端から飛び出して水槽3の外に飛び散ってしまったり、蓋18の裏面や、上部枠体17に付着したり、洗濯機1が置かれている床面に落ちたりせず、洗濯機1や洗濯機1が置かれている床面を汚してしまうのを防止することができる。 Further, by providing a notch in a part of the balancer rib provided on the opposite side of the rotation center of the washing and dewatering tub of the softener charging port, the softener may overflow from the softener charging port. From the notch, it can flow into the gap between the fluid balancer and the water tank and can flow to the bottom of the water tank. Thereby, for example, even when the softener flows backward from the softener automatic outflow device 21 and overflows from the softener inlet 22 during the first dehydration process, due to the centrifugal force of the washing and dewatering tank 4, Since the softening agent that has flowed out in the reverse direction flows from the notch 24 a of the balancer rib 24 toward the water tank 3, the softening agent jumps out of the softener charging port 22 and the upper ends of the balancer ribs 24 and out of the water tank 3. The floor surface on which the washing machine 1 or the washing machine 1 is placed without splashing, adhering to the back surface of the lid 18 or the upper frame 17 or falling on the floor surface on which the washing machine 1 is placed. Can be prevented from getting dirty.

リント用循環水路10および散水ノズル用循環水路11は、パルセータ5の下側羽根6外周のポンプ室12から洗濯兼脱水槽4の上部に至るように設けられ、上部に着脱可能なリントフィルタ13および散水ノズル14がそれぞれ設けられている。排水弁15は水槽3内の洗濯水を排水するものであり、給水弁16は水槽3内に給水するものである。洗濯機1の上部を構成する上部枠体17に蓋18が開閉自在に設けられ、また、その前方に制御手段19が設けられている。洗濯兼脱水槽4の上部には脱水時の振動を低減させるための流体バランサ20が設けられ、この流体バランサ20の中心側に柔軟剤自動流出装置21が設けられている。   The lint circulation water channel 10 and the sprinkling nozzle circulation water channel 11 are provided so as to extend from the pump chamber 12 on the outer periphery of the lower blade 6 of the pulsator 5 to the upper part of the washing and dewatering tub 4, and a lint filter 13 detachably attached to the upper part. A watering nozzle 14 is provided. The drain valve 15 drains the washing water in the water tank 3, and the water supply valve 16 supplies water into the water tank 3. A lid 18 is provided on the upper frame 17 constituting the upper portion of the washing machine 1 so as to be freely opened and closed, and a control means 19 is provided in front of the lid 18. A fluid balancer 20 for reducing vibration during dehydration is provided at the top of the washing and dewatering tub 4, and a softener automatic outflow device 21 is provided at the center of the fluid balancer 20.

給水弁16からの水道水が水槽3内の洗濯兼脱水槽4内に確実に給水されるように、給水弁16に連通する給水口16aは、洗濯兼脱水槽4の流体バランサ20の開口部20aの略上方に配置されている。   The water supply port 16 a communicating with the water supply valve 16 is an opening of the fluid balancer 20 of the washing and dewatering tank 4 so that the tap water from the water supply valve 16 is reliably supplied into the washing and dewatering tank 4 in the water tank 3. It is arranged substantially above 20a.

なお、図2に示すように、流体バランサ20の柔軟剤自動流出装置21が配置される部分に、柔軟剤自動流出装置21に連通する柔軟剤投入口22を設けているので、使用者は、柔軟剤を柔軟剤投入口22から柔軟剤自動流出装置21に投入することができる。   In addition, as shown in FIG. 2, since the softening agent inlet 22 which communicates with the softening agent automatic outflow apparatus 21 is provided in the part in which the softening agent automatic outflow apparatus 21 of the fluid balancer 20 is disposed, The softening agent can be put into the softening agent automatic outlet 21 through the softening agent inlet 22.

被洗浄物23が、洗濯兼脱水槽4から飛び出すのを防止するために、図1に示すように、流体バランサ20の略上部にバランサリブ24を流体バランサ20の内周に沿って設けている。柔軟剤投入口22近傍にも、バランサリブ24を、図2に示すように、柔軟剤投入口22の、洗濯兼脱水槽4の回転中心側に設けている。   In order to prevent the object to be cleaned 23 from jumping out of the washing and dewatering tub 4, as shown in FIG. 1, balancer ribs 24 are provided along the inner periphery of the fluid balancer 20 at substantially the upper part of the fluid balancer 20. A balancer rib 24 is also provided in the vicinity of the softener charging port 22 on the rotation center side of the washing and dewatering tub 4 of the softener charging port 22 as shown in FIG.

これにより、給水口16aから洗濯水が給水されるときに、洗濯水の一部が被洗浄物23によって柔軟剤自動流出装置21側に飛び散って、流体バランサ20の柔軟剤投入口22を介して柔軟剤自動流出装置21内に浸入するのを防止することができる。   Thereby, when the washing water is supplied from the water supply port 16 a, a part of the washing water is scattered to the softener automatic outflow device 21 side by the article to be cleaned 23 and passes through the softener inlet 22 of the fluid balancer 20. It is possible to prevent the softener automatic outflow device 21 from entering.

また、被洗浄物23が柔軟剤投入口22の上部に載ってしまうのを防止することができる。   Moreover, it can prevent that the to-be-cleaned object 23 mounts on the upper part of the softening agent inlet 22.

上記構成において動作を説明すると、使用者が蓋18を開いて衣類などの被洗浄物23を洗濯兼脱水槽4内に投入し、洗濯機1の電源を入れてスタートボタン(図示しない)を押すと、駆動手段7により洗濯兼脱水槽4が正逆回転して被洗浄物23の量を検知する。そして、操作部(図示しない)に必要な洗剤量を表示するので、使用者はまず、洗剤を所定の位置に投入し(洗濯兼脱水槽4内でもよい)、次に、所定量の柔軟剤を柔軟剤投入口22から投入し、その後、蓋18を閉じることで、給水弁16を介して給水口16aから洗濯兼脱水槽4内に所定量の洗濯水が供給される。   To explain the operation in the above configuration, the user opens the lid 18, puts an object to be cleaned 23 such as clothes into the washing and dewatering tub 4, turns on the washing machine 1, and presses a start button (not shown). Then, the washing and dewatering tub 4 rotates forward and backward by the driving means 7 to detect the amount of the object 23 to be cleaned. Since the amount of detergent required is displayed on the operation unit (not shown), the user first puts the detergent into a predetermined position (may be in the washing and dehydrating tub 4), and then a predetermined amount of softening agent. Then, a predetermined amount of washing water is supplied from the water supply port 16a into the washing and dewatering tub 4 through the water supply valve 16.

所定量の洗濯水が供給されるとパルセータ5が正逆回転して被洗浄物23を洗う洗い行程が行われる。   When a predetermined amount of washing water is supplied, the pulsator 5 rotates forward and backward to perform the washing process of washing the article 23 to be cleaned.

所定時間の洗い行程が終了すると排水弁15により水槽3内の洗濯水が洗濯機1外へ排水される。そして、洗濯水が排水されると洗濯兼脱水槽4が高速回転して(例えば300r/min)、第一の脱水行程が行われる。   When the washing process for a predetermined time is completed, the washing water in the water tub 3 is drained out of the washing machine 1 by the drain valve 15. When the washing water is drained, the washing and dewatering tank 4 rotates at a high speed (for example, 300 r / min), and the first dewatering process is performed.

第一の脱水行程が終了すると、すすぎ水が供給されてパルセータ5が正逆回転し、被洗浄物23をすすぐ第一のすすぎ行程が行われる。第一のすすぎ行程が終了すると、水槽3内の洗濯水が洗濯機1外へ排水され、第二の脱水行程(例えば洗濯兼脱水槽4の回転数:300r/minで洗濯兼脱水槽4が高速回転する)が行われる。さらに、すすぎ水が供給されて最終すすぎ行程が行われ、その後、水槽3内の洗濯水が排水され、第三の脱水行程(例えば洗濯兼脱水槽4の回転数:800r/minで洗濯兼脱水槽4が高速回転する)が行われる。   When the first dehydration process is completed, the rinsing water is supplied, the pulsator 5 rotates forward and backward, and the first rinsing process for rinsing the article 23 to be cleaned is performed. When the first rinsing process is completed, the washing water in the water tub 3 is drained out of the washing machine 1, and the second dehydration process (for example, the number of rotations of the washing and dehydrating tank 4 is 300 r / min) Rotate at high speed). Further, the rinsing water is supplied and the final rinsing process is performed, and then the washing water in the water tank 3 is drained, and the third dehydration process (for example, the number of rotations of the washing and dehydrating tank 4 is 800 r / min. The water tank 4 rotates at high speed).

第三の脱水行程が行われると、運転が終了する。   When the third dehydration process is performed, the operation ends.

次に、この運転にしたがって柔軟剤自動流出装置21内を流れる柔軟剤の動作を説明する。   Next, the operation of the softening agent flowing in the softening agent automatic outflow device 21 according to this operation will be described.

図3は、柔軟剤が流れる柔軟剤自動流出装置21内の要部横断面図、図4(a)は、柔軟剤の柔軟剤自動流出装置21の第2室48への移動時の断面図、図4(b)は、第4室52への柔軟剤の移動時の断面図、図4(c)は、柔軟剤自動流出装置21から水槽3への柔軟剤流出時の断面図である。   FIG. 3 is a cross-sectional view of the main part in the softener automatic efflux device 21 through which the softener flows, and FIG. 4A is a cross-sectional view of the softener softener automatic efflux device 21 when it moves to the second chamber 48. 4B is a cross-sectional view when the softening agent is moved to the fourth chamber 52, and FIG. 4C is a cross-sectional view when the softening agent is discharged from the softening agent automatic outflow device 21 to the water tank 3. .

図3および図4に示すように、流体バランサ20に設けた柔軟剤自動流出装置21の外壁44と内壁45との間に柔軟剤の貯留部46を設けるとともに、この貯留部46から、第1移動通路47を介して第1室48を設け、また、第2移動通路49を介して第2室50を設け、また、第3移動通路51を介して第3室52を設け、さらに、第4移動通路53および流出通路54を介して柔軟剤流出口55を設けている。   As shown in FIGS. 3 and 4, a softener reservoir 46 is provided between the outer wall 44 and the inner wall 45 of the softener automatic spill device 21 provided in the fluid balancer 20. A first chamber 48 is provided via the moving passage 47, a second chamber 50 is provided via the second moving passage 49, a third chamber 52 is provided via the third moving passage 51, and A softener outlet 55 is provided via the four moving passages 53 and the outflow passage 54.

上記構成において柔軟剤の移動を説明すると、まず、洗い開始時に、柔軟剤投入口22から貯留部46に投入された柔軟剤は、洗い終了後の第1の脱水行程時の遠心力により、矢印aのように第1移動通路47を通って第1室48に移動する。第1室48に移動した柔軟剤は第1の脱水行程終了までbのように第一の脱水行程時の遠心力により第1室48の外側壁56に張り付いた状態となっている。第1の脱水行程終了後、すなわち第1のすすぎ行程時に遠心力はなくなるので、柔軟剤は矢印cのように第2移動通路49を通り、第2室50に移動する。   The movement of the softening agent in the above configuration will be described. First, at the start of washing, the softening agent introduced into the storage unit 46 from the softening agent inlet 22 is subjected to an arrow due to the centrifugal force during the first dehydration process after washing. It moves to the 1st chamber 48 through the 1st movement channel | path 47 like a. The softening agent that has moved to the first chamber 48 is stuck to the outer wall 56 of the first chamber 48 by the centrifugal force during the first dehydration stroke as shown in b until the end of the first dehydration stroke. Since the centrifugal force disappears after the first dehydration process, that is, during the first rinsing process, the softening agent moves to the second chamber 50 through the second movement passage 49 as indicated by an arrow c.

つぎに、柔軟剤は第1のすすぎ行程終了後の第2の脱水行程時の遠心力により、矢印dのように第3移動通路51を通り第3室52に移動する。第3室52に移動した柔軟剤は第2の脱水行程終了までeのように遠心力により第3室52の外側壁57に張り付いた状態となっている。第2の脱水行程終了後、すなわち最終すすぎ行程時に遠心力はなくなるので、柔軟剤は矢印fのように第4移動通路53を通り、さらに矢印gのように流出通路54を通った後、矢印hのように柔軟剤流出口55より出て、水槽3と洗濯兼脱水槽4の間に落下する。   Next, the softening agent moves to the third chamber 52 through the third movement path 51 as indicated by an arrow d by the centrifugal force during the second dehydration process after the end of the first rinsing process. The softening agent that has moved to the third chamber 52 is stuck to the outer wall 57 of the third chamber 52 by centrifugal force as shown by e until the end of the second dehydration process. Since the centrifugal force disappears after the end of the second dehydration process, that is, in the final rinsing process, the softener passes through the fourth movement path 53 as indicated by the arrow f, and further passes through the outflow path 54 as indicated by the arrow g. It exits from the softener outlet 55 as shown in h and falls between the water tub 3 and the washing and dewatering tub 4.

このように構成された本実施例によれば、図1〜図5に示すように、流体バランサ20の略上部にバランサリブ24を流体バランサ20の内周に沿って設け、柔軟剤投入口22の、洗濯兼脱水槽4の回転中心側にも、バランサリブ24を設けることにより、被洗浄物23が、洗濯兼脱水槽4から飛び出すのを防止することができるとともに、給水口16aから洗濯水が給水されるときに、洗濯水の一部が被洗浄物23によって柔軟剤自動流出装置21側に飛び散って、流体バランサ20の柔軟剤投入口22を介して柔軟剤自動流出装置21内に浸入するのを防止することができる。   According to the present embodiment configured as described above, as shown in FIGS. 1 to 5, the balancer rib 24 is provided along the inner periphery of the fluid balancer 20 at substantially the upper portion of the fluid balancer 20, Further, by providing the balancer rib 24 on the rotation center side of the washing / dehydrating tub 4 as well, it is possible to prevent the article to be cleaned 23 from jumping out of the washing / dehydrating tub 4, and the wash water is supplied from the water supply port 16a. At that time, a part of the washing water is scattered by the article to be cleaned 23 toward the softener automatic spill device 21 and enters the softener automatic spill device 21 through the softener inlet 22 of the fluid balancer 20. Can be prevented.

したがって、洗い行程の洗濯水の給水中に、柔軟剤投入口22に洗濯水が浸入しないので、柔軟剤自動流出装置21の貯留部46内にある柔軟剤と洗濯水とが混ざり合って柔軟剤の濃度が低下したりせず、また柔軟剤自動流出装置21の貯留部46から柔軟剤が溢れ出して、洗い行程時に所定量の柔軟剤が柔軟剤自動流出装置21の貯留部46に蓄えられずに、最終のすすぎ行程で所定量の柔軟剤が洗濯兼脱水槽4に投入できなかったりすることがないので、柔軟剤による所定の性能を得ることができる。   Therefore, since the washing water does not enter the softening agent inlet 22 during the washing water supply in the washing process, the softening agent and the washing water in the storage unit 46 of the softening agent automatic drain device 21 are mixed and the softening agent. The softener overflows from the reservoir 46 of the softener automatic spill device 21 and a predetermined amount of softener is stored in the reservoir 46 of the softener automatic spill device 21 during the washing process. In addition, since a predetermined amount of the softening agent cannot be put into the washing and dewatering tub 4 in the final rinsing process, a predetermined performance by the softening agent can be obtained.

また、図2に示すように、柔軟剤投入口22の周辺にバランサリブ24を設けることにより、バランサリブ24により、柔軟剤をどの範囲に投入すれば柔軟剤自動流出装置21内に確実に供給できるかを明確にすることができるので、使用者は、柔軟剤を柔軟剤投入口22に投入しやすくなり、所定量の柔軟剤を柔軟剤自動流出装置21の貯留部46に供給することができ、最終のすすぎ行程で所定量の柔軟剤を洗濯兼脱水槽4に投入し、柔軟剤による所定の性能を得ることが確実にできるようになる。   Further, as shown in FIG. 2, by providing a balancer rib 24 around the softener inlet 22, it is possible to reliably supply the softener into the softener automatic flow-out device 21 by which range the softener is charged by the balancer rib 24. Therefore, the user can easily put the softening agent into the softening agent inlet 22, and can supply a predetermined amount of the softening agent to the storage unit 46 of the softening agent automatic outflow device 21, In the final rinsing process, a predetermined amount of softening agent is put into the washing and dehydrating tub 4 so that it is possible to reliably obtain a predetermined performance by the softening agent.

また、柔軟剤は粘性の高い液体のため、洗濯機1を長期に渡り使用すると、柔軟剤自動流出装置21の柔軟剤が流れる経路の一部、例えば、第1移動通路47、第2移動通路49、第3移動通路51等に柔軟剤が固着して、柔軟剤が流れる経路の一部が柔軟剤により塞がってしまって、柔軟剤自動流出装置21内を柔軟剤が流れないという不具合が生じる可能性がある。仮にこのような状態で柔軟剤を使用者が柔軟剤投入口22から投入すると、柔軟剤が柔軟剤投入口22から溢れ出てしまい、そのまま、第一の脱水行程を行うと、柔軟剤投入口22から溢れ出た柔軟剤は、柔軟剤投入口22およびバランサリブ24の上端から飛び出して、水槽3の外に飛び散ってしまい、蓋18の裏面や、上部枠体17に付着したり、洗濯機1が置かれている床面に落ちたりして、洗濯機1や洗濯機1が置かれている床面を汚してしまう可能性がある。   Further, since the softening agent is a highly viscous liquid, when the washing machine 1 is used for a long period of time, a part of the path through which the softening agent of the softening agent automatic outflow device 21 flows, for example, the first moving path 47 and the second moving path. 49, the softening agent adheres to the third moving passage 51 and the like, and a part of the path through which the softening agent flows is blocked by the softening agent, so that the softening agent does not flow in the softening agent automatic outflow device 21. there is a possibility. If the user inputs the softener from the softener inlet 22 in such a state, the softener overflows from the softener inlet 22, and if the first dehydration process is performed as it is, the softener inlet The softening agent overflowing from 22 jumps out from the upper ends of the softening agent inlet 22 and the balancer rib 24 and scatters out of the water tub 3, adheres to the back surface of the lid 18, the upper frame 17, or the washing machine 1. Or the floor surface on which the washing machine 1 is placed may be soiled.

そこで、そのような事態が生じないようにするために、図2に示すように、柔軟剤投入口22の洗濯兼脱水槽4の回転中心と反対側にあるバランサリブ24の一部に切り欠き部24aを設けることにより、柔軟剤は、柔軟剤投入口22から溢れ出てきても、切り欠き部24aから、流体バランサ20と水槽3との隙間に流れていき、水槽3の底部に流れていくようにすることができる。これにより、例えば、第一の脱水行程中に柔軟剤自動流出装置21から柔軟剤が逆流して柔軟剤投入口22から溢れ出てきたような場合でも、洗濯兼脱水槽4の遠心力により、逆流して出てきた柔軟剤は、バランサリブ24の切り欠き部24aから水槽3に向かって流れていくので、柔軟剤が、柔軟剤投入口22およびバランサリブ24の上端から飛び出して水槽3の外に飛び散ってしまったり、蓋18の裏面や、上部枠体17に付着したり、洗濯機1が置かれている床面に落ちたりせず、洗濯機1や洗濯機1が置かれている床面を汚してしまうのを防止することができる。   Therefore, in order to prevent such a situation from occurring, as shown in FIG. 2, a cutout portion is formed in a part of the balancer rib 24 on the side opposite to the rotation center of the washing / dehydrating tub 4 of the softener charging port 22. By providing 24 a, even if the softening agent overflows from the softening agent inlet 22, it flows from the notch 24 a to the gap between the fluid balancer 20 and the water tank 3 and flows to the bottom of the water tank 3. Can be. Thereby, for example, even when the softener flows backward from the softener automatic outflow device 21 and overflows from the softener inlet 22 during the first dehydration process, due to the centrifugal force of the washing and dewatering tank 4, Since the softening agent that has flowed out in the reverse direction flows from the notch 24 a of the balancer rib 24 toward the water tank 3, the softening agent jumps out of the softener charging port 22 and the upper ends of the balancer ribs 24 and out of the water tank 3. The floor surface on which the washing machine 1 or the washing machine 1 is placed without splashing, adhering to the back surface of the lid 18 or the upper frame 17 or falling on the floor surface on which the washing machine 1 is placed. Can be prevented from getting dirty.

以上のように、本発明にかかる洗濯機は、柔軟剤による所定の性能を得ることができるので、家庭用の洗濯機だけでなく、業務用の洗濯機の用途にも適用できる。   As described above, since the washing machine according to the present invention can obtain a predetermined performance by the softener, it can be applied not only to a domestic washing machine but also to an industrial washing machine.
