　［洗剤投入装置］
　図４は、第１の実施の形態におけるドラム式洗濯機の洗剤収容容器の外観斜視図である。図５は、第１の実施の形態におけるドラム式洗濯機の貯留部回りを示す一部透視した斜視図である。なお、図５では、洗剤収容容器６の図示は省略している。 [Detergent injection device]
FIG. 4 is an external perspective view of the detergent container of the drum-type washing machine according to the first embodiment. FIG. 5 is a partially perspective view showing the periphery of the storage portion of the drum-type washing machine according to the first embodiment. In FIG. 5, the detergent storage container 6 is not shown.
　図４に示すように、洗剤収容容器６には、洗剤を投入する洗剤収容部２７と、仕上剤を投入する仕上剤収容部９と、が設けられている。 As shown in FIG. 4, the detergent storage container 6 is provided with a detergent storage unit 27 for charging the detergent and a finishing agent storage unit 9 for charging the finishing agent.
　図５に示すように、枠体３８の下部には、蛇腹状の送水部材３１が接続されており、送水部材３１は、貯留部材４０と接続されている。貯留部材４０は、屈曲部分である貯留部４２、貯留部４２の下流に設けられた第１吐出流路２８、第１吐出流路２８の途中に形成された分流経路用開口４１、第１吐出流路２８の下流に設けられた第２吐出流路２９、及び、第２吐出流路２９の下流で環状パッキン８を介して回転ドラム１０と連通する吐出接続部３０、とを含んでいる。送水部材３１、貯留部４２、及び第１吐出流路２８は、第１の流路を構成している。 As shown in FIG. 5, a bellows-shaped water supply member 31 is connected to the lower part of the frame body 38, and the water supply member 31 is connected to the storage member 40. The storage member 40 includes a storage portion 42 which is a bent portion, a first discharge flow path 28 provided downstream of the storage portion 42, a flow diversion path opening 41 formed in the middle of the first discharge flow path 28, and a first discharge. It includes a second discharge flow path 29 provided downstream of the flow path 28, and a discharge connection portion 30 communicating with the rotary drum 10 via the annular packing 8 downstream of the second discharge flow path 29. The water supply member 31, the storage unit 42, and the first discharge flow path 28 form a first flow path.
　貯留部材４０は、取り付け状態において、貯留部４２が最も低くなるように配置されている。貯留部４２は、略Ｖ状に形成された貯留部材４０の屈曲部であるため、常に残水する構造となっている。この残水により、水槽内部で発生する水蒸気や加熱された空気等が洗剤収容容器６に流入するのを防止することができる。 The storage member 40 is arranged so that the storage unit 42 is the lowest in the attached state. Since the storage portion 42 is a bent portion of the storage member 40 formed in a substantially V shape, it has a structure in which water always remains. The residual water can prevent water vapor generated inside the water tank, heated air, and the like from flowing into the detergent container 6.
　第１吐出流路２８は、貯留部４２から上方に延伸して形成されている。第１吐出流路２８の上方には、後述する分流経路４３と接続される分流経路用開口４１が形成されている。分流経路用開口４１は、第１吐出流路２８よりも径が小さくなるように形成されている。分流経路用開口４１よりも上方を第２吐出流路２９とする。吐出接続部３０は、第１吐出流路２８の上部である第２吐出流路２９から環状パッキン８に向かって延伸するように、略筒状に形成されている。環状パッキン８には、吐出接続部３０と対向するように吐出口８１が設けられている。吐出口８１は、回転ドラム１０の内部に延伸する略筒形状に形成されており、通過する液体を背面に向かって吐出可能に構成されている。第２吐出流路２９、吐出接続部３０、及び吐出口８１は、第３の流路を構成している。 The first discharge flow path 28 is formed so as to extend upward from the storage portion 42. Above the first discharge flow path 28, a diversion path opening 41 connected to the diversion path 43 described later is formed. The flow dividing path opening 41 is formed so that the diameter is smaller than that of the first discharge flow path 28. The second discharge flow path 29 is above the opening for the diversion path 41. The discharge connection portion 30 is formed in a substantially tubular shape so as to extend from the second discharge flow path 29, which is the upper part of the first discharge flow path 28, toward the annular packing 8. The annular packing 8 is provided with a discharge port 81 so as to face the discharge connection portion 30. The discharge port 81 is formed in a substantially tubular shape extending inside the rotary drum 10, and is configured to be able to discharge the passing liquid toward the back surface. The second discharge flow path 29, the discharge connection portion 30, and the discharge port 81 form a third flow path.
　分流経路４３は、分流経路用開口４１と接続されている。分流経路４３は、下方に延伸して伸縮ホース４５と接続されており、伸縮ホース４５と分流経路４３との接続部分は、係留部材４４によって本体筐体１の内壁に係止されている。伸縮ホース４５は、蛇腹状に形成されており、揺動可能に水槽１１の下部と接続されている。これにより、伸縮ホース４５は、水槽１１の揺動を吸収する。分流経路用開口４１、分流経路４３及び伸縮ホース４５は、第２の流路を構成している。この第２の流路は、第１の流路から分岐して構成されており、第３の流路の迂回経路である。 The diversion path 43 is connected to the diversion path opening 41. The diversion path 43 extends downward and is connected to the telescopic hose 45, and the connecting portion between the telescopic hose 45 and the diversion path 43 is locked to the inner wall of the main body housing 1 by the mooring member 44. The telescopic hose 45 is formed in a bellows shape and is swingably connected to the lower part of the water tank 11. As a result, the telescopic hose 45 absorbs the swing of the water tank 11. The diversion path opening 41, the diversion path 43, and the telescopic hose 45 form a second flow path. This second flow path is configured to be branched from the first flow path, and is a detour route of the third flow path.
　以上のように構成されたドラム式洗濯機について、以下その動作、作用を説明する。 The operation and operation of the drum-type washing machine configured as described above will be described below.
　［洗濯運転］
　電源スイッチ３３のＯＮにより、本体筐体１に対して商用電源から電力が供給されて操作可能になる。使用者は、扉体３を開き、回転ドラム１０内に洗濯物を投入する。使用者は操作部４により各種洗濯コースを選択する。例えば、使用者が『洗い』から『脱水』までの各行程を一貫して運転する『全行程』を選択し、運転開始を選択すると、本体筐体１の運転が開始される。本実施の形態におけるドラム式洗濯機は、運転を開始すると、布量検知手段３７を駆動して投入した洗濯物の布量を検知し、表示部５に、水位、必要な洗剤量、仕上剤量、及び洗濯時間を順次表示させる。 [Washing operation]
When the power switch 33 is turned on, electric power is supplied to the main body housing 1 from a commercial power source to enable operation. The user opens the door body 3 and puts the laundry into the rotating drum 10. The user selects various washing courses by the operation unit 4. For example, when the user selects "whole process" for consistently operating each process from "washing" to "dehydration" and selects operation start, the operation of the main body housing 1 is started. When the drum-type washing machine according to the present embodiment starts operation, it drives the cloth amount detecting means 37 to detect the amount of laundry cloth put in, and displays the water level, the required amount of detergent, and the finishing agent on the display unit 5. The amount and washing time are displayed in sequence.
　使用者が洗剤収容容器６を引き出すと、洗剤収容部２７及び仕上剤収容部９が露出する。使用者は、表示部５を確認し、表示された必要量の洗剤を洗剤収容部２７へ投入し、表示された必要量の仕上剤を仕上剤収容部９へ投入する。 When the user pulls out the detergent storage container 6, the detergent storage unit 27 and the finishing agent storage unit 9 are exposed. The user confirms the display unit 5, charges the displayed required amount of detergent into the detergent storage unit 27, and charges the displayed required amount of finishing agent into the finishing agent storage unit 9.
　使用者が液体洗剤を投入した場合、注入した液体洗剤の一部は送水部材３１へと流下し、貯留部材４０に到達する。貯留部４２の内部は常に残水しているため、流下した液体洗剤は残水した水と混合する。混合した液体洗剤及び水は、液面が分流経路４３の接続位置よりも高くなると、分流経路４３及び伸縮ホース４５を流下し、水槽１１へ送り込まれる。 When the user puts in the liquid detergent, a part of the injected liquid detergent flows down to the water supply member 31 and reaches the storage member 40. Since the inside of the storage unit 42 always has residual water, the liquid detergent that has flowed down is mixed with the residual water. When the liquid level of the mixed liquid detergent and water becomes higher than the connection position of the diversion path 43, the mixed liquid detergent and water flow down the diversion path 43 and the telescopic hose 45 and are sent to the water tank 11.
　その後、制御部５３は、モータ１２、給水弁２５、排水弁１８などの動作を制御し、洗い、すすぎ、脱水などの各行程を実行する。 After that, the control unit 53 controls the operations of the motor 12, the water supply valve 25, the drain valve 18, and the like, and executes each process such as washing, rinsing, and dehydration.
　洗い行程において、制御部５３は給水弁２５を開放する。給水弁２５から供給された水道水は、給水部材３５内を通過した後、洗剤収容容器６の洗剤収容部２７に対向する所定の孔から水が吐出する。 In the washing process, the control unit 53 opens the water supply valve 25. After passing through the water supply member 35, the tap water supplied from the water supply valve 25 is discharged from a predetermined hole facing the detergent storage portion 27 of the detergent storage container 6.
　洗剤収容部２７に粉末洗剤が投入されている場合、吐出された水と粉末洗剤とが混合され、送水部材３１を介し、貯留部材４０に送り込まれる。洗剤収容部２７に液体洗剤が投入されている場合、吐出された水と洗剤収容部２７に残留する液体洗剤とが混合され、送水部材３１を介し、貯留部材４０に送り込まれる。貯留部材４０に送り込まれた水及び洗剤は、後述のように、水槽１１及び回転ドラム１０の内部に送り込まれる。 When the powder detergent is charged into the detergent accommodating portion 27, the discharged water and the powder detergent are mixed and sent to the storage member 40 via the water supply member 31. When the liquid detergent is charged into the detergent storage unit 27, the discharged water and the liquid detergent remaining in the detergent storage unit 27 are mixed and sent to the storage member 40 via the water supply member 31. The water and detergent sent to the storage member 40 are sent to the inside of the water tank 11 and the rotary drum 10 as described later.
　給水が完了すると洗い行程が開始される。洗い行程においては、回転ドラム１０の回転による洗い撹拌が行われ、洗濯物に付着した汚れを落とす。所定時間経過後、洗濯水が排水され、すすぎ行程が開始される。 When the water supply is completed, the washing process will start. In the washing process, washing and stirring are performed by rotating the rotating drum 10, and dirt adhering to the laundry is removed. After a lapse of a predetermined time, the washing water is drained and the rinsing process is started.
　すすぎ行程が開始されると、給水が実施される。水道水は、給水部材３５内を通って所定の孔から吐出され、仕上剤収容部９を満水にする。満水状態では、サイフォン現象により仕上剤収容部９内の水と仕上剤の混合液が送水部材３１から水槽１１内に送られる。そして、所定水位まで給水されると、すすぎ攪拌が行われる。所定時間が経過すると、本体筐体１の外へ洗濯水が排水される。 When the rinsing process is started, water supply will be carried out. The tap water passes through the water supply member 35 and is discharged from a predetermined hole to fill the finishing agent accommodating portion 9. In the full state, the mixed liquid of the water and the finishing agent in the finishing agent accommodating portion 9 is sent from the water supply member 31 into the water tank 11 by the siphon phenomenon. Then, when water is supplied to a predetermined water level, rinsing and stirring are performed. When the predetermined time elapses, the washing water is drained to the outside of the main body housing 1.
　次に、脱水行程が実行される。脱水工程において、吐出接続部３０と連通する吐出口８１は、環状パッキン８に設けられているので、回転ドラム１０が高速回転して水槽１１が振動しても、振動の影響を受けづらい。脱水行程が終了すると、洗濯が終了する。 Next, the dehydration process is executed. In the dehydration step, since the discharge port 81 communicating with the discharge connection portion 30 is provided in the annular packing 8, even if the rotating drum 10 rotates at high speed and the water tank 11 vibrates, it is not easily affected by the vibration. When the dehydration process is complete, washing is complete.
　［洗濯運転における貯留部材］
　前述の通り、洗濯運転において使用者が液体洗剤を投入すると、注入した液体洗剤の一部が貯留部材４０に到達する。従って、第２の流路である分流経路４３及び伸縮ホース４５が存在しない場合、液体洗剤と貯留部材４０に残水した水の混合液は、第１吐出流路２８、第２吐出流路２９及び吐出接続部３０を経由して吐出口８１に到達する。すると、使用者は、扉体３を介して、吐出口８１から液体が吐出されたことを視認できるため、不安感や不快感を覚えることがある。また、扉体３を開いた状態で液体洗剤を投入した場合、投入口７を介して液体洗剤が本体筐体１の外に漏れる虞がある。 [Storage member in washing operation]
As described above, when the user injects the liquid detergent in the washing operation, a part of the injected liquid detergent reaches the storage member 40. Therefore, when the diversion path 43 and the telescopic hose 45, which are the second flow paths, do not exist, the mixed liquid of the liquid detergent and the water remaining in the storage member 40 is the first discharge flow path 28 and the second discharge flow path 29. And reaches the discharge port 81 via the discharge connection portion 30. Then, since the user can visually recognize that the liquid has been discharged from the discharge port 81 through the door body 3, he / she may feel anxiety or discomfort. Further, when the liquid detergent is charged with the door body 3 open, the liquid detergent may leak to the outside of the main body housing 1 through the charging port 7.
　本実施の形態では、第３の流路に対する迂回経路として第２の流路を設けることにより、液体洗剤を投入する際に、液体が吐出口８１に到達しない構成にしている。 In the present embodiment, the second flow path is provided as a detour route to the third flow path so that the liquid does not reach the discharge port 81 when the liquid detergent is added.
　次に、洗剤収容部２７に給水が行われ、水と洗剤の混合液は貯留部材４０へと流下する。流量が充分少量である場合、貯留部４２に到達した水と洗剤の混合液は、第１吐出流路２８、分流経路用開口４１、分流経路４３、及び伸縮ホース４５を経由して水槽１１へ到達する。 Next, water is supplied to the detergent storage unit 27, and the mixed solution of water and detergent flows down to the storage member 40. When the flow rate is sufficiently small, the mixed solution of water and detergent that has reached the storage section 42 goes to the water tank 11 via the first discharge flow path 28, the flow diversion path opening 41, the diversion path 43, and the telescopic hose 45. To reach.
　水と洗剤の混合液の流量が、単位時間当たりで分流経路用開口４１を通過可能な水量を上回った場合、又は分流経路４３の最大容量を上回る量であった場合、混合液の一部は第２吐出流路２９へ進む。その後、混合液は、第２吐出流路２９、吐出接続部３０、及び吐出口８１を通過して、回転ドラム１０内へ吐出される。 If the flow rate of the water / detergent mixture exceeds the amount of water that can pass through the diversion path opening 41 per unit time, or if the flow rate exceeds the maximum capacity of the diversion path 43, part of the mixture will be partially Proceed to the second discharge flow path 29. After that, the mixed liquid passes through the second discharge flow path 29, the discharge connection portion 30, and the discharge port 81, and is discharged into the rotary drum 10.
　このとき、分流経路４３及び伸縮ホース４５による経路を通過する液量は、第２吐出流路２９、吐出接続部３０、及び吐出口８１による経路を通過する液量よりも少なく、混合液の全量に占める割合は小さい。吐出口８１から充分な量の吐水が為されることで、回転ドラム１０の内部前方に収容された衣類に対して充分な給水を行わせることができる。 At this time, the amount of liquid passing through the path of the diversion path 43 and the telescopic hose 45 is smaller than the amount of liquid passing through the path of the second discharge flow path 29, the discharge connection portion 30, and the discharge port 81, and the total amount of the mixed liquid is small. The ratio to is small. By discharging a sufficient amount of water from the discharge port 81, it is possible to supply sufficient water to the clothes housed in front of the inside of the rotating drum 10.
　［作用等］
　以上のように、本実施の形態におけるドラム式洗濯機は、本体筐体１と、本体筐体１の内部に揺動自在に支持された水槽１１と、水槽１１の内部に回転自在に配設された回転ドラム１０と、水槽１１又は回転ドラム１０に洗剤を供給する洗剤投入装置を備える。洗剤投入装置は、洗剤が投入される洗剤収容容器６と、洗剤収容容器６と接続され、液体を貯留可能に形成された貯留部４２を含む第１の流路と、貯留部４２の下流且つ上方において第１の流路と連通する。さらに、水槽１１と接続される第２の流路と、第２の流路の下流且つ上方において第１の流路と連通するとともに、回転ドラム１０の内部と連通する第３の流路と、を含む。 [Action, etc.]
As described above, the drum-type washing machine according to the present embodiment is rotatably arranged inside the main body housing 1, the water tank 11 swayably supported inside the main body housing 1, and the inside of the water tank 11. The rotating drum 10 is provided with a detergent charging device for supplying detergent to the water tank 11 or the rotating drum 10. The detergent charging device includes a detergent storage container 6 into which detergent is charged, a first flow path including a storage unit 42 connected to the detergent storage container 6 and formed so as to store a liquid, and downstream of the storage unit 42. It communicates with the first flow path above. Further, a second flow path connected to the water tank 11 and a third flow path that communicates with the first flow path downstream and above the second flow path and also communicates with the inside of the rotary drum 10. including.
　この構成により、少量の液体は、第３の流路に流下して水槽１１に到達するため、第２の流路を通過して回転ドラム１０の内部に吐出されない。そのため、使用者が洗剤を供給する際、洗剤収容容器６に注いだ洗剤が回転ドラム１０の内部にすぐに到達することを抑制できる。 With this configuration, a small amount of liquid flows down into the third flow path and reaches the water tank 11, so that it is not discharged into the rotating drum 10 through the second flow path. Therefore, when the user supplies the detergent, it is possible to prevent the detergent poured into the detergent storage container 6 from immediately reaching the inside of the rotating drum 10.
　本実施の形態のように、第２の流路は、水槽１１との接続部分を含み、揺動自在に本体筐体１に固定されている伸縮ホース４５を含んでもよい。 As in the present embodiment, the second flow path may include a connecting portion with the water tank 11 and may include a telescopic hose 45 which is swingably fixed to the main body housing 1.
　この構成により、伸縮ホース４５は、水槽１１の揺動を吸収するとともに、係留部材４４により本体筐体１と固定されているので分流経路４３に振動を伝達しない。 With this configuration, the telescopic hose 45 absorbs the vibration of the water tank 11 and is fixed to the main body housing 1 by the mooring member 44, so that the vibration is not transmitted to the diversion path 43.

The opening of the second flow path may be any one that communicates with the inside of the rotating drum 10. Therefore, the opening of the second flow path may be provided in addition to the annular packing 8.
　第１実施の形態では貯留部を含む第１の流路の一例として、送水部材３１及び貯留部材４０を説明した。貯留部材４０は、最も低くなる位置に貯留部４２が形成されていればよいので、略Ｖ字状に屈曲する形状に限定されない。例えば、貯留部材４０は、略Ｕ字状等であってもよい。 In the first embodiment, the water supply member 31 and the storage member 40 have been described as an example of the first flow path including the storage unit.

For example, the storage member 40 may be substantially U-shaped or the like.
　以下、図面を参照しながら、第１の実施の形態におけるドラム式洗濯機における他の作用効果を詳細に説明する。なお、添付図面及び以下の説明によって本発明が限定されるものではない。 Hereinafter, other effects of the drum-type washing machine according to the first embodiment will be described in detail with reference to the drawings.

　すすぎ行程において、回転ドラム５３０は、洗い行程よりも低い洗剤濃度を有する水中で衣類を攪拌する。また、すすぎ行程において、収容槽５１０への給水及び収容槽５１０からの排水が繰り返される。この結果、洗剤は、衣類から適切に取り除かれる。 In the rinsing process, the rotating drum 530 agitates the clothes in water having a detergent concentration lower than that in the washing process. Further, in the rinsing process, water supply to the storage tank 510 and drainage from the storage tank 510 are repeated. As a result, the detergent is properly removed from the garment.
　脱水行程において、回転ドラム５３０は、遠心力を利用して、衣類から脱水する。この結果、衣類の乾燥が促進される。 In the dehydration process, the rotating drum 530 dehydrates the clothes using centrifugal force. As a result, the drying of clothes is promoted.
　乾燥行程において、収容槽５１０の水槽５４０内に乾燥空気が供給される。乾燥空気の湿度は低く、且つ、温度は高いので、衣類は収容槽５１０内で適切に乾燥される。乾燥空気が供給されている間、回転ドラム５３０は、衣類を攪拌する。この結果、衣類は、適切に乾燥される。 In the drying process, dry air is supplied into the water tank 540 of the storage tank 510. Since the humidity of the dry air is low and the temperature is high, the clothes are properly dried in the storage tank 510. The rotating drum 530 agitates the garment while the dry air is being supplied. As a result, the garment is properly dried.
　（給水装置）
　給水装置４００は、上述の洗い行程及びすすぎ行程において、収容槽５１０に水を供給する。 (Water supply device)
The water supply device 400 supplies water to the storage tank 510 in the washing process and the rinsing process described above.
　給水装置４００は、蛇口に接続される給水口４１０と、給水弁４２０と、洗剤が収容される洗剤投入部４３０及び液体仕上剤が収容される液体仕上剤収容部４４０を有する洗剤収容容器４６０と、を含む。なお、洗剤収容容器４６０は、前後が長手方向であり、洗剤や液体仕上剤を投入するために、本体筐体２００の前面側から引き出し自在となっている。更に、給水装置４００は、第１給水経路４２１と、第２給水経路４２２と、第３給水経路４２３と、泡生成部４５０とを備えている。なお、泡生成部４５０については、図１１以降で詳述する。 The water supply device 400 includes a detergent storage container 460 having a water supply port 410 connected to a faucet, a water supply valve 420, a detergent input unit 430 for storing detergent, and a liquid finish agent storage unit 440 for storing liquid finish. ,including. The detergent storage container 460 has a longitudinal direction in the front-rear direction, and can be freely pulled out from the front side of the main body housing 200 in order to charge the detergent and the liquid finishing agent. Further, the water supply device 400 includes a first water supply path 421, a second water supply path 422, a third water supply path 423, and a foam generation unit 450. The foam generation unit 450 will be described in detail in FIGS. 11 and 11 and later.
　給水口４１０に供給された水は、給水弁４２０に至る。 The water supplied to the water supply port 410 reaches the water supply valve 420.
　給水弁４２０は、２個以上の水路が開閉可能な複数弁構成である。従って、給水弁４２０は、洗剤投入部４３０を通じて収容槽５１０に水が供給される第１給水経路４２１と、液体仕上剤収容部４４０を通じて収容槽５１０に水が供給される第２給水経路４２２と、泡生成部４５０に水が直接的に向かう第３給水経路４２３とを切り替えることができる。 The water supply valve 420 has a multi-valve configuration in which two or more water channels can be opened and closed. Therefore, the water supply valve 420 includes a first water supply path 421 in which water is supplied to the storage tank 510 through the detergent input section 430 and a second water supply path 422 in which water is supplied to the storage tank 510 through the liquid finish agent storage section 440. , The third water supply path 423, in which water directly directs to the foam generating unit 450, can be switched.
　洗い行程にて、給水弁４２０が第１給水経路４２１を開くと、水は、洗剤が投入されている洗剤投入部４３０に流入し、水及び洗剤が混合される。そして、水と洗剤の混合液が、回転ドラム５３０に流入する。 When the water supply valve 420 opens the first water supply path 421 in the washing process, the water flows into the detergent charging section 430 in which the detergent is charged, and the water and the detergent are mixed. Then, the mixed solution of water and detergent flows into the rotary drum 530.
　また、すすぎ行程にて、給水弁４２０が第２給水経路４２２を開くと、水は、液体仕上剤が投入されている液体仕上剤収容部４４０に流入し、水及び液体仕上剤洗剤が混合される。そして、水と液体仕上剤の混合液が、収容槽５１０に流入する。 Further, when the water supply valve 420 opens the second water supply path 422 in the rinsing process, water flows into the liquid finish agent accommodating portion 440 in which the liquid finish agent is charged, and the water and the liquid finish agent detergent are mixed. To. Then, the mixed liquid of water and the liquid finishing agent flows into the storage tank 510.
　なお、第１給水経路４２１は、例えば、洗剤投入部４３０に洗剤が投入されていない時には、すすぎ行程において用いられる。この結果、水が洗剤投入部４３０を通じて収容槽５１０に直接的に供給される。また、第２給水経路４２２は、例えば、液体仕上剤収容部４４０に液体仕上剤が投入されていない時には、洗い行程に用いられてもよい。 The first water supply path 421 is used in the rinsing process, for example, when the detergent is not charged into the detergent charging unit 430. As a result, water is directly supplied to the storage tank 510 through the detergent charging section 430. Further, the second water supply path 422 may be used in the washing process, for example, when the liquid finishing agent is not charged into the liquid finishing agent accommodating portion 440.
　（乾燥装置）
　乾燥装置６００は、収容槽５１０から吸気管６５０を介して送り出された湿った空気を受けるエアフィルタ６１０と、エアフィルタ６１０を通過した空気と熱を交換する熱交換部６２０と、熱交換部６２０を通過した湿気が除去された暖かい空気を、送気管６６０を介して収容槽５１０へ送り出す送風ファン６３０とを備えている。エアフィルタ６１０は、収容槽５１０から送り出された空気からリントを除去する。したがって、清浄化された空気が、熱交換部６２０に流入する。 (Drying device)
The drying device 600 includes an air filter 610 that receives moist air sent from the storage tank 510 via an intake pipe 650, a heat exchange unit 620 that exchanges heat with the air that has passed through the air filter 610, and a heat exchange unit 620. It is provided with a blower fan 630 that sends warm air from which moisture has passed through the air through the air supply pipe 660 to the storage tank 510. The air filter 610 removes lint from the air sent out from the containment tank 510. Therefore, the purified air flows into the heat exchange unit 620.
　（洗剤投入装置）
　図１１は、第１の実施の形態におけるドラム式洗濯機の上半分部の縦断面図である。図１２は、第１の実施の形態におけるドラム式洗濯機の泡生成部の一部透視した正面から見た断面図である。 (Detergent injection device)
FIG. 11 is a vertical cross-sectional view of the upper half of the drum-type washing machine according to the first embodiment. FIG. 12 is a cross-sectional view seen from the front of a part of the foam generating portion of the drum type washing machine according to the first embodiment.
　図１１、図１２において、泡生成部４５０は、泡を生成するための装置である。泡生成部４５０にて気泡となり体積を増した洗濯液は、収容槽５１０に送られ、衣類の上に行き渡る。洗濯液が衣類に接触し浸透すると、気泡は泡膜となり衣類を覆う。泡膜は高濃度の界面活性剤を含むので、衣類の汚れを効率的に除去することができる。 In FIGS. 11 and 12, the bubble generation unit 450 is a device for generating bubbles. The washing liquid which has become bubbles and has increased in volume in the foam generation unit 450 is sent to the storage tank 510 and spreads on the clothes. When the washing liquid comes into contact with the clothes and permeates, the bubbles form a foam film and cover the clothes. Since the foam film contains a high concentration of surfactant, stains on clothes can be efficiently removed.
　泡生成部４５０は、洗剤収容容器４６０よりも下方で、回転ドラム５３０の回転軸ＲＸよりも上方の位置で、水槽５４０の前周壁５４５に取り付けられており、泡生成部筐体４５１に隔壁４５６を形成することで略Ｕ字状に構成されている。 The foam generating unit 450 is attached to the front peripheral wall 545 of the water tank 540 at a position below the detergent storage container 460 and above the rotating shaft RX of the rotating drum 530, and the partition wall 456 is attached to the foam generating unit housing 451. Is formed into a substantially U-shape.
　泡生成部４５０は、泡生成部筐体４５１の上面側には、洗剤収容容器４６０に形成した洗剤投入部４３０、液体仕上剤収容部４４０を介して第１給水経路４２１、第２給水経路４２２と連通する流入口４５３が接続されており、更に、第３給水経路４２３の一端である噴出口４５５が接続されている。 The foam generation unit 450 has a first water supply path 421 and a second water supply path 422 on the upper surface side of the foam generation unit housing 451 via a detergent charging unit 430 formed in the detergent storage container 460 and a liquid finishing agent storage unit 440. The inflow port 453 communicating with the water inlet 453 is connected, and the spout 455 which is one end of the third water supply path 423 is further connected.
　泡生成部筐体４５１の最下部には、隔壁４５６により泡生成室４５２が区画されており、隔壁４５６を挟んで流入口４５３側と反対側に流出口４５４が形成されている。泡生成室４５２底面は、流出口４５４に向かって上方へ傾斜して形成され、流出口４５４は、泡生成室４５２底部の延長線上に形成されている。なお、隔壁４５６の先端Ａは、流出口４５４（貯留ライン）までよりも低い位置に位置している。 A foam generation chamber 452 is partitioned by a partition wall 456 at the lowermost portion of the foam generation unit housing 451, and an outflow port 454 is formed on the side opposite to the inflow port 453 side with the partition wall 456 interposed therebetween. The bottom surface of the foam generation chamber 452 is formed so as to be inclined upward toward the outlet 454, and the outlet 454 is formed on an extension line of the bottom portion of the foam generation chamber 452. The tip A of the partition wall 456 is located at a position lower than the outlet 454 (storage line).
　泡生成室４５２は、洗剤投入部４３０に投入されて水と共に流入してきた洗剤を貯留する。第３給水経路４２３を介して噴出口４５５から流速の速い水が噴出され、貯留した洗剤液の液面に衝突すると、多くの洗剤泡が発生する。そして、洗剤泡は、流速の速い水とともに流出口４５４から収容槽５１０内に流れ込む。 The foam generation chamber 452 stores the detergent that has been charged into the detergent charging unit 430 and has flowed in together with the water. When water having a high flow velocity is ejected from the ejection port 455 through the third water supply path 423 and collides with the liquid surface of the stored detergent liquid, many detergent bubbles are generated. Then, the detergent foam flows into the storage tank 510 from the outflow port 454 together with the water having a high flow velocity.
　ここで、泡生成部筐体４５１内部を隔壁４５６により区画することにより、泡生成室４５２の流路面積を絞ることになり、噴出口４５５からの流速を上げることができ、より多くの洗剤泡を発生させることができる。 Here, by partitioning the inside of the foam generation unit housing 451 by the partition wall 456, the flow path area of the foam generation chamber 452 can be narrowed, the flow velocity from the ejection port 455 can be increased, and more detergent bubbles can be obtained. Can be generated.
　また、収容槽５１０に存在する蒸気又は臭気が逆流し、泡生成部４５０を通過して洗剤投入部４３０から漏れ出すことがある。泡生成室４５２は、封水された状態において、蒸気又は臭気の逆流を防ぐことができる。本実施の形態のように、隔壁４５６を設けて泡生成室４５２の流路面積を絞ることで、流路を封水するために必要な水量を小さくできる。これにより、少量の水でも確実に泡生成室４５２を水封できる。 In addition, steam or odor existing in the storage tank 510 may flow back, pass through the foam generation unit 450, and leak from the detergent charging unit 430. The foam generation chamber 452 can prevent backflow of steam or odor in a sealed state. By providing the partition wall 456 and narrowing the flow path area of the foam generation chamber 452 as in the present embodiment, the amount of water required to seal the flow path can be reduced. As a result, the foam generation chamber 452 can be reliably sealed with a small amount of water.
　また、泡生成部筐体４５１には、流出口４５４の上流側で、かつ、泡生成室４５２底面に貯留した洗剤液より上方の下流側に、バイパス流出口４２７が形成されバイパス経路４２５が接続されている。 Further, in the foam generation unit housing 451, a bypass outlet 427 is formed on the upstream side of the outlet 454 and on the downstream side above the detergent solution stored in the bottom surface of the foam generation chamber 452, and the bypass path 425 is connected. Has been done.
　バイパス経路４２５の他端は、水槽５４０に揺動自在に接続されており、収容槽５１０から伝達される振動を吸収する。流入口４５３を介して貯留された水と洗剤の混合液が貯留ライン以上になると、混合液は溢れてバイパス流出口４２７からバイパス経路４２５、伸縮ホース４２６を介して水槽５４０に流れ込むようになっている。 The other end of the bypass path 425 is swingably connected to the water tank 540 and absorbs the vibration transmitted from the storage tank 510. When the mixed solution of water and detergent stored through the inflow port 453 exceeds the storage line, the mixed solution overflows and flows from the bypass outlet 427 into the water tank 540 via the bypass path 425 and the telescopic hose 426. There is.
　洗剤収容容器４６０、流入口４５３、泡生成部４５０、バイパス経路４２５、伸縮ホース４２６は、洗剤を含む水を収容槽５１０に送り込む洗剤投入装置としての役割を果たす。 The detergent storage container 460, the inflow port 453, the foam generation unit 450, the bypass path 425, and the telescopic hose 426 serve as a detergent charging device that sends water containing detergent to the storage tank 510.
　（洗濯運転）
　以上のように構成されたドラム式洗濯機について、以下その動作、作用を説明する。 (Washing operation)
The operation and operation of the drum-type washing machine configured as described above will be described below.
　使用者は、運転前に洗剤収容容器４６０を引き出し、洗濯用の液体洗剤を洗剤投入部４３０に投入する。液体洗剤は、徐々に、流入口４５３から泡生成部４５０に流下し、最下部の泡生成室４５２に溜まる。なお、泡生成室４５２には貯留ラインまで液体洗剤が溜まるようになっており、それ以上の量の液体洗剤が投入された場合は、バイパス流出口４２７からバイパス経路４２５、伸縮ホース４２６を介して水槽５４０に流れ込む。 The user pulls out the detergent container 460 before operation and puts the liquid detergent for washing into the detergent charging section 430. The liquid detergent gradually flows down from the inflow port 453 to the foam generation unit 450 and accumulates in the lowermost foam generation chamber 452. The foam generation chamber 452 is designed to collect liquid detergent up to the storage line, and when a larger amount of liquid detergent is charged, the bypass outlet 427 passes through the bypass path 425 and the telescopic hose 426. It flows into the water tank 540.
　運転がスタートすると、給水弁４２０が駆動され、第１給水経路４２１を経由して洗剤投入部４３０に給水される。水は、洗剤投入部４３０とそれ以降の経路に残った液体洗剤を洗い流しながら、泡生成部４５０の流入口４５３から泡生成部４５０内に流下する。 When the operation starts, the water supply valve 420 is driven, and water is supplied to the detergent inlet 430 via the first water supply path 421. The water flows down into the foam generating unit 450 from the inflow port 453 of the foam generating unit 450 while washing away the liquid detergent remaining in the detergent charging unit 430 and the subsequent paths.
　洗剤投入部４３０に粉末洗剤が投入された場合は、水と洗剤の混合液となって流入口４５３から泡生成部４５０の泡生成室４５２内に流入する。泡生成室４５２で溢れた混合液は、バイパス流出口から、バイパス経路４２５、伸縮ホース４２６を介して水槽５４０に流れ込む。 When powder detergent is charged into the detergent charging section 430, it becomes a mixed solution of water and detergent and flows into the foam generating chamber 452 of the foam generating section 450 from the inflow port 453. The mixed solution overflowing in the foam generation chamber 452 flows from the bypass outlet into the water tank 540 via the bypass path 425 and the telescopic hose 426.
　続いて、給水弁４２０が開き、第３給水経路４２３を介して噴出口４５５から流速の速い水が噴出される。噴出口４５５から噴出された水は、泡生成室４５２内に溜まった洗剤と水との混合液の水面に勢いよく衝突し、洗剤液を攪拌して空気を取り込み、洗剤泡を発生させる。発生した洗剤泡は、泡生成部４５０に設けられた流出口４５４側へ流れていき、流出口４５４から収容槽５１０の回転ドラム５３０内の衣類に供給される。 Subsequently, the water supply valve 420 is opened, and water having a high flow velocity is ejected from the spout 455 via the third water supply path 423. The water ejected from the spout 455 vigorously collides with the water surface of the mixture of the detergent and water accumulated in the foam generation chamber 452, agitates the detergent liquid, takes in air, and generates detergent bubbles. The generated detergent foam flows to the outlet 454 side provided in the foam generation unit 450, and is supplied from the outlet 454 to the clothes in the rotary drum 530 of the storage tank 510.
　泡生成部４５０において発生した洗剤泡は、泡生成部４５０上方の流出口４５４から直接、回転ドラム５３０内に供給される。これにより、洗剤泡が衣類全体に素早く浸透し、泡に密集する界面活性剤が汚れを吸着して浮かせるので、頑固な汚れもすっきり落ちるなど洗浄性能を発揮できる。 The detergent foam generated in the foam generating unit 450 is directly supplied into the rotating drum 530 from the outlet 454 above the foam generating unit 450. As a result, the detergent foam quickly permeates the entire clothing, and the surfactant that concentrates on the foam adsorbs and floats the dirt, so that even stubborn dirt can be removed cleanly and the cleaning performance can be exhibited.
　所定水位まで回転ドラム５３０内に給水されると、モータ５２０が駆動し、回転ドラム５３０が回転して洗い攪拌動作が行われ、多くの洗剤泡が衣類に作用して、高い洗浄効果が発揮される。 When water is supplied into the rotating drum 530 to a predetermined water level, the motor 520 is driven, the rotating drum 530 is rotated to perform a washing and stirring operation, and many detergent bubbles act on clothes to exhibit a high cleaning effect. To.
　次に、１回目のすすぎ行程においては、排水、中間脱水が終わると、給水弁４２０が第１給水経路４２１を開き、洗剤の無くなった洗剤投入部４３０、泡生成部４５０を経由して水槽５４０内に給水され、所定水位まで給水されると、モータ５２０が駆動し、回転ドラム５３０が回転してすすぎ攪拌が行われる。 Next, in the first rinsing process, when drainage and intermediate dehydration are completed, the water supply valve 420 opens the first water supply path 421, and the water tank 540 passes through the detergent input section 430 and the foam generation section 450 where the detergent has run out. When the water is supplied to the inside and reaches a predetermined water level, the motor 520 is driven and the rotary drum 530 is rotated to perform rinsing and stirring.
　最終すすぎ行程においては、排水、中間脱水が終わると、給水弁４２０が第２給水経路４２２を開くと、水は、事前に液体仕上剤が投入されている洗剤収容容器４６０の液体仕上剤収容部４４０に流入し、水及び液体仕上剤洗剤が混合される。そして、水と液体仕上剤の混合液が、水槽５４０に流入される。所定水位まで回転ドラム５３０内に給水されると、モータ５２０が駆動し、回転ドラム５３０が回転して、衣類に液体仕上剤の効果を与えながら、すすぎ攪拌が行われる。 In the final rinsing process, when drainage and intermediate dehydration are completed, the water supply valve 420 opens the second water supply path 422, and the water is supplied to the liquid finish container 460, which is filled with the liquid finish in advance. It flows into 440 and is mixed with water and liquid finishing detergent. Then, the mixed liquid of water and the liquid finishing agent flows into the water tank 540. When water is supplied into the rotary drum 530 to a predetermined water level, the motor 520 is driven and the rotary drum 530 is rotated to perform rinsing and stirring while giving the effect of a liquid finishing agent to the clothes.
　すすぎ攪拌が終わり、排水された後、最終脱水行程が行われ、その後、必要に応じて、乾燥行程が行われる。 After rinsing and stirring are completed and drained, the final dehydration process is performed, and then the drying process is performed if necessary.
　ここで、すすぎ行程終了時点で泡生成部４５０に残水した洗濯水が、脱水行程における水槽５４０の振動の大小によって、バイパス経路４２５に流入するか、バイパス経路４２５に流入せず泡生成室４５２に留まることになる。従って、脱水中に、洗濯水が流出口４５４から水槽５４０に流入して脱水している衣類にかかることは無い。 Here, the washing water remaining in the foam generation unit 450 at the end of the rinsing process flows into the bypass path 425 or does not flow into the bypass path 425 depending on the magnitude of the vibration of the water tank 540 in the dehydration process, and the foam generation chamber 452. Will stay in. Therefore, during dehydration, the washing water does not flow into the water tank 540 from the outlet 454 and hit the dehydrated clothes.
　また、脱水行程、及び、乾燥行程においては、すすぎ行程で残水した水によって、泡生成室４５２を水封して、トラップ効果を発揮することになり、収容槽５１０に存在する臭気が逆流して、泡生成部４５０を通過して洗剤投入部４３０から漏れ出すことを防ぐ。 Further, in the dehydration process and the drying process, the foam generation chamber 452 is sealed with the water remaining in the rinsing process to exert a trap effect, and the odor present in the storage tank 510 flows back. This prevents the foam from leaking from the detergent charging unit 430 after passing through the foam generating unit 450.
　（作用等）
　以上のように、本実施の形態におけるドラム式洗濯機は、本体筐体２００と、本体筐体２００内に揺動自在に防振支持された水槽５４０と、水槽５４０に回転自在に内包され、洗濯物を収容する回転ドラム５３０と、回転ドラム５３０を回転駆動するモータと、水槽５４０又は回転ドラム５３０に洗剤を供給する洗剤投入装置と、洗剤投入装置に給水する給水装置４００と、を備える。洗剤投入装置は、洗剤が投入される洗剤投入部４３０と、洗剤投入部４３０の下方に設けられ、洗剤投入部４３０から流下した洗剤が貯留される泡生成室４５２と、泡生成室４５２の上方に設けられ、給水装置４００から供給された水を泡生成室４５２の液面に落下させる噴出口４５５と、を含む。 (Action, etc.)
As described above, the drum-type washing machine according to the present embodiment is rotatably contained in the main body housing 200, the water tank 540 oscillatingly and vibration-proof supported in the main body housing 200, and the water tank 540. It includes a rotary drum 530 for accommodating laundry, a motor for rotationally driving the rotary drum 530, a detergent charging device for supplying detergent to the water tank 540 or the rotating drum 530, and a water supply device 400 for supplying water to the detergent charging device. The detergent charging device is provided below the detergent charging unit 430 into which the detergent is charged and the detergent charging unit 430, and is above the foam generating chamber 452 and the foam generating chamber 452 in which the detergent flowing down from the detergent charging unit 430 is stored. Includes a spout 455, which is provided in the water supply device 400 to drop the water supplied from the water supply device 400 onto the liquid level of the foam generation chamber 452.
　この構成により、洗剤投入装置の一部である泡生成部４５０において、泡生成室４５２に貯留された洗剤液と水とを衝突させ、泡を生成することができる。そのため、泡生成専用の経路を設ける等の複雑な装置を用いることなく、簡易な構成で泡を生成する装置を実現できる。 With this configuration, in the foam generation unit 450, which is a part of the detergent charging device, the detergent liquid stored in the foam generation chamber 452 and water can collide with each other to generate foam. Therefore, it is possible to realize a device that generates bubbles with a simple configuration without using a complicated device such as providing a path dedicated to bubble generation.
　本実施の形態のように、給水装置４００は、洗剤投入部４３０と接続され、洗剤投入部４３０を介して泡生成室４５２に水を流下させる第１給水経路と、噴出口４５５と接続される第３給水経路４２３と、を含んでもよい。 As in the present embodiment, the water supply device 400 is connected to the detergent charging unit 430, and is connected to a first water supply path for flowing water down to the foam generation chamber 452 via the detergent charging unit 430 and a spout 455. The third water supply path 423 and the like may be included.
　これにより、第１給水経路と別に設けられた第３給水経路４２３により、泡生成室４５２に貯留された洗濯液に給水できる。 As a result, water can be supplied to the washing liquid stored in the foam generation chamber 452 by the third water supply path 423 provided separately from the first water supply path.
　本実施の形態のように、洗剤投入装置は、略Ｕ字状に形成された泡生成部４５０を含み、泡生成室４５２は、泡生成部４５０の下部として形成されてもよい。 As in the present embodiment, the detergent charging device includes a foam generation unit 450 formed in a substantially U shape, and the foam generation chamber 452 may be formed as a lower portion of the foam generation unit 450.
　この構成により、泡生成部４５０を小型に形成できるので、洗剤投入装置を省スペース化できる。 With this configuration, the foam generating unit 450 can be formed in a small size, so that the space for the detergent charging device can be saved.
　本実施の形態のように、洗剤投入装置は、泡生成室４５２の下流側において、泡生成部４５０と前記水槽とを接続するバイパス経路４２５と、泡生成部４５０とバイパス経路４２５との接続部分の下流且つ上方に設けられ、泡生成部４５０と前記収容槽とを連通させる流出経路と、を含んでもよい。 As in the present embodiment, in the detergent charging device, on the downstream side of the foam generation chamber 452, a bypass path 425 connecting the foam generation unit 450 and the water tank, and a connection portion between the foam generation unit 450 and the bypass path 425 It may include an outflow path which is provided downstream and above the above and communicates the foam generation unit 450 and the storage tank.
　この構成により、貯留ラインを超えた洗剤液は、バイパス経路４２５を通って水槽５４０に送り込まれる。そのため、泡生成室４５２が溢れることを防ぐことができる。 With this configuration, the detergent solution that has crossed the storage line is sent to the water tank 540 through the bypass path 425. Therefore, it is possible to prevent the foam generation chamber 452 from overflowing.
　（第２の実施の形態）
　図１３は、第２の実施の形態におけるドラム式洗濯機の泡生成部の一部透視した正面から見た断面図である。 (Second Embodiment)
FIG. 13 is a cross-sectional view seen from the front of a part of the foam generating portion of the drum-type washing machine according to the second embodiment.
　なお、泡生成部に追加した形状以外の各部位については、図６～図１２に示す第１の実施の形態と同一であるため、同じ部位については、同一番号を付して、説明を省略する。 Since each part other than the shape added to the foam generation part is the same as the first embodiment shown in FIGS. 6 to 12, the same part is given the same number and the description is omitted. To do.
　（誘導壁）
　図１３において、バイパス経路４２５への接続口であるバイパス流出口４２７を覆うように誘導壁４５７が設けられている。 (Induction wall)
In FIG. 13, a guide wall 457 is provided so as to cover the bypass outlet 427, which is a connection port to the bypass path 425.
　誘導壁４５７は、略半円状をしており、下流側である流出口４５４側だけに略半円状に開口した開口部４２８を有しており、バイパス流出口４２７と連通している。 The guide wall 457 has a substantially semicircular shape, and has an opening 428 that opens in a substantially semicircular shape only on the downstream side of the outlet 454, and communicates with the bypass outlet 427.
　以上のように構成されたドラム式洗濯機について、以下その動作、作用を説明する。 The operation and operation of the drum-type washing machine configured as described above will be described below.
　洗い行程において、液体洗剤あるいは粉末洗剤と水の混合液が泡生成室４５２内に貯留している状態で、給水弁４２０が開き、第３給水経路４２３を介して泡生成部４５０の噴出口４５５から流速の速い水が噴出されると、溜まった洗剤と水との混合液の水面に勢いよく衝突して洗剤液を攪拌することで、空気を泡の形で液体に取り込む構成になり洗剤泡が発生する。発生した洗剤泡は、誘導壁４５７にそって流れ、バイパス流出口４２７からバイパス経路４２５に流入することなく、泡生成部４５０に設けられた流出口４５４側へ流れていき、流出口４５４から収容槽５１０の回転ドラム５３０内の衣類に供給される。 In the washing process, the water supply valve 420 opens with the liquid detergent or a mixture of powder detergent and water stored in the foam generation chamber 452, and the outlet 455 of the foam generation unit 450 passes through the third water supply path 423. When water with a high flow velocity is ejected from the detergent, it vigorously collides with the surface of the mixed liquid of the accumulated detergent and water and stirs the detergent liquid, so that air is taken into the liquid in the form of bubbles. Occurs. The generated detergent foam flows along the guide wall 457, flows to the outlet 454 side provided in the foam generation unit 450 without flowing from the bypass outlet 427 into the bypass path 425, and is housed from the outlet 454. It is supplied to the clothes in the rotary drum 530 of the tank 510.
　（作用等）
　以上のように、本実施の形態における泡生成部４５０は、バイパス経路４２５と連通する開口部分であるバイパス流出口４２７において、上流側を覆う誘導壁が設けられている。 (Action, etc.)
As described above, the bubble generation unit 450 in the present embodiment is provided with a guide wall covering the upstream side at the bypass outlet 427, which is an opening portion communicating with the bypass path 425.
　これにより、発生した洗剤泡は、誘導壁４５７に案内され、バイパス流出口４２７から流出することなく、泡生成部４５０に設けられた流出口４５４側へ流れていく。そのため、洗剤泡がバイパス経路４２５から流出することを防ぎ、効率よく洗剤泡を生成できる。 As a result, the generated detergent foam is guided by the guide wall 457 and flows to the outlet 454 side provided in the foam generation unit 450 without flowing out from the bypass outlet 427. Therefore, it is possible to prevent the detergent foam from flowing out from the bypass path 425 and efficiently generate the detergent foam.
　（他の実施の形態）
　以上のように、本出願において開示する技術の例示として、第１の実施の形態及び第２の実施の形態を説明した。しかしながら、本開示における技術は、これに限定されない。 (Other embodiments)
As described above, the first embodiment and the second embodiment have been described as examples of the techniques disclosed in the present application. However, the techniques in this disclosure are not limited to this.
　そこで、以下、他の実施の形態を例示する。 Therefore, other embodiments will be illustrated below.
　第１の実施の形態及び第２の実施の形態では、洗濯機の一例としてドラム式洗濯機を説明した。洗濯機は、洗剤を使用するものであればよい。したがって、洗濯機は、ドラム式洗濯機に限定されず、縦型洗濯機又は二槽式洗濯機であってもよい。 In the first embodiment and the second embodiment, the drum type washing machine has been described as an example of the washing machine. The washing machine may be one that uses detergent. Therefore, the washing machine is not limited to the drum type washing machine, and may be a vertical type washing machine or a two-tank type washing machine.
　第１の実施の形態及び第２の実施の形態では、泡生成部の一例として泡生成部４５０を説明した。泡生成部は、貯留部を含んでいればよいので、泡生成部４５０の形状に限定されず、図１４のように泡生成室４５２から上方に延伸する形状であってもよい。なお、図１４は、他の実施の形態におけるドラム式洗濯機の泡生成部の一部透視した正面から見た断面図である。 In the first embodiment and the second embodiment, the foam generating unit 450 has been described as an example of the foam generating unit. Since the foam generating portion may include a storage portion, the shape is not limited to the shape of the foam generating portion 450, and may be a shape extending upward from the foam generating chamber 452 as shown in FIG. Note that FIG. 14 is a cross-sectional view seen from the front of a part of the foam generating portion of the drum-type washing machine according to the other embodiment.
　第１の実施の形態及び第２の実施の形態では、略Ｕ字状の泡生成部の一例として、図１２及び図１３の形状を説明した。略Ｕ字状は、図１２及び図１３の形状に限定されず、Ｖ字状、コ字状、折り畳み形状、それらの何れかを含む形状、等であってもよい。 In the first embodiment and the second embodiment, the shapes of FIGS. 12 and 13 have been described as an example of a substantially U-shaped bubble generating portion. The substantially U-shape is not limited to the shapes shown in FIGS. 12 and 13, and may be a V-shape, a U-shape, a folded shape, a shape including any of them, and the like.
　第１の実施の形態及び第２の実施の形態では、流出経路の一例として、泡生成部筐体４５１の一部として形成された流出口４５４を説明した。流出経路は、貯留部と回転ドラムとを連通させる経路であればよいので、泡生成部筐体４５１の一部として形成されたものに限定されない。流出経路は、泡生成部に接続された別部品であってもよい。なお、流出経路は、回転ドラムと直接接続されていなくてもよい。例えば、流出経路は、収容槽の前方部分を水封する窓パッキンに接続されていてもよい。窓パッキンの一部を流出経路として形成することで、回転ドラムに収容された衣類に、上方から効率良く洗剤泡を振りかけることができる。また、窓パッキンは、ゴム等の弾性素材により形成されることが多く、収容槽の振動を吸収する。流出経路を窓パッキンに接続することにより、泡生成部に振動が伝達されることを抑止できるので、泡生成部に弾性のない硬質の部材を使用することができる。 In the first embodiment and the second embodiment, the outlet 454 formed as a part of the foam generation unit housing 451 has been described as an example of the outflow route. The outflow path may be any path that communicates the storage unit and the rotating drum, and is not limited to the one formed as a part of the foam generation unit housing 451. The outflow path may be a separate component connected to the foam generator. The outflow path does not have to be directly connected to the rotating drum. For example, the outflow route may be connected to a window packing that seals the front portion of the containment tank with water. By forming a part of the window packing as an outflow path, the detergent foam can be efficiently sprinkled on the clothes housed in the rotating drum from above. Further, the window packing is often formed of an elastic material such as rubber, and absorbs the vibration of the storage tank. By connecting the outflow path to the window packing, it is possible to prevent vibration from being transmitted to the foam generating portion, so that a rigid member having no elasticity can be used for the foam generating portion.
