　銀クリスタルユニット収容部１６の内底部には、銀クリスタルユニット収容部の排出口３０ｃが形成されており、銀クリスタルユニット１５から排出された水を下方に吐出する。 A discharge port 30c of the silver crystal unit accommodating portion is formed in the inner bottom portion of the silver crystal unit accommodating portion 16, and the water discharged from the silver crystal unit accommodating portion 15 is discharged downward.
　（銀クリスタルユニット収容部）
　図５は、第１の実施の形態における洗濯機の銀クリスタルユニット収容部周囲を示す横断面図である。図６Ａは、第１の実施の形態における洗濯機の銀クリスタルユニットを外した状態の銀クリスタルユニット収容部の周囲を示す外観斜視図である。図６Ｂは、第１の実施の形態における洗濯機の銀クリスタルユニットを装着した状態の銀クリスタルユニット収容部の周囲を示す外観斜視図である。 (Silver crystal unit housing)
FIG. 5 is a cross-sectional view showing the periphery of the silver crystal unit housing portion of the washing machine according to the first embodiment. FIG. 6A is an external perspective view showing the periphery of the silver crystal unit accommodating portion in the state where the silver crystal unit of the washing machine in the first embodiment is removed. FIG. 6B is an external perspective view showing the periphery of the silver crystal unit accommodating portion in the state where the silver crystal unit of the washing machine according to the first embodiment is attached.
　図５、図６Ａおよび図６Ｂに示すように、銀クリスタルユニット収容部１６は、箱状に形成されており、銀クリスタルユニット１５を着脱可能に構成されている。 As shown in FIGS. 5, 6A and 6B, the silver crystal unit accommodating portion 16 is formed in a box shape, and the silver crystal unit 15 is detachably configured.
　銀クリスタルユニット収容部１６の内周壁には、傾斜リブ１６ｃが上下に伸びて複数個形成されている。傾斜リブ１６ｃは、下方になるに従って突出して形成されており、銀クリスタルユニット１５が下方に挿入される際に銀クリスタルユニット１５を滑らかに案内する。傾斜リブ１６ｃの上下方向の端面は、銀クリスタルユニット１５が銀クリスタルユニット収容部１６に完全に挿入された状態において、銀クリスタルユニット１５と当接する。これにより、銀クリスタルユニット１５は、銀クリスタルユニット収容部１６に保持された状態となり、洗剤ケース９が逆さにされた場合でも落下しない。 A plurality of inclined ribs 16c extend vertically on the inner peripheral wall of the silver crystal unit accommodating portion 16. The inclined rib 16c is formed so as to project downward, and smoothly guides the silver crystal unit 15 when the silver crystal unit 15 is inserted downward. The vertical end face of the inclined rib 16c comes into contact with the silver crystal unit 15 in a state where the silver crystal unit 15 is completely inserted into the silver crystal unit accommodating portion 16. As a result, the silver crystal unit 15 is held in the silver crystal unit accommodating portion 16 and does not fall even when the detergent case 9 is turned upside down.
　また、銀クリスタルユニット１５には、後述するヒンジ部２２が設けられており、銀クリスタルユニット収容部１６には、銀クリスタルユニット収容部側ツメ１６ｂが設けられている。ヒンジ部２２は、ヒンジ構造として働くだけでなく、銀クリスタルユニット収容部側ツメ１６ｂと係合可能に構成されている。使用者が、銀クリスタルユニット１５を銀クリスタルユニット収容部１６に挿入すると、ヒンジ部２２が銀クリスタルユニット収容部側ツメ１６ｂと係合する。これにより、銀クリスタルユニット１５は、銀クリスタルユニット収容部１６に装着された状態となる。 Further, the silver crystal unit 15 is provided with a hinge portion 22 described later, and the silver crystal unit accommodating portion 16 is provided with a claw 16b on the silver crystal unit accommodating portion side. The hinge portion 22 not only acts as a hinge structure, but is also configured to be engageable with the silver crystal unit accommodating portion side claw 16b. When the user inserts the silver crystal unit 15 into the silver crystal unit accommodating portion 16, the hinge portion 22 engages with the silver crystal unit accommodating portion side claw 16b. As a result, the silver crystal unit 15 is attached to the silver crystal unit accommodating portion 16.
　なお、傾斜リブ１６ｃによる銀クリスタルユニット１５の保持と、ヒンジ部２２による銀クリスタルユニット１５の装着は、どちらか一方を備えてもよいし、両方を備えてもよい。 The holding of the silver crystal unit 15 by the inclined rib 16c and the mounting of the silver crystal unit 15 by the hinge portion 22 may be provided with either one or both.
　また、銀クリスタルユニット１５は、一側面にネジボス部２３（後述）が突出しており、全体形状が点対称とならないように構成されている。また、銀クリスタルユニット収容部１６は、ネジボス部２３と対向する位置に切り欠き１６ａが形成されており、ネジボス部２３と干渉しないように構成されている。ネジボス部２３が切り欠き１６ａに挿入されることにより、銀クリスタルユニット１５は、銀クリスタルユニット収容部１６に対して正位置（後述）すなわち、正しい収納位置となるよう位置決めされる。そのため、使用者が銀クリスタルユニット１５を装着する際に、誤った向きで取り付けることを抑制できる。なお、銀クリスタルユニット１５に設けられる位置決め用の構造は、ネジボス部２３でなくてもよい。 Further, the silver crystal unit 15 has a screw boss portion 23 (described later) protruding from one side surface, and is configured so that the overall shape is not point-symmetrical. Further, the silver crystal unit accommodating portion 16 has a notch 16a formed at a position facing the screw boss portion 23 so as not to interfere with the screw boss portion 23. By inserting the screw boss portion 23 into the notch 16a, the silver crystal unit 15 is positioned so as to be in a normal position (described later), that is, a correct storage position with respect to the silver crystal unit accommodating portion 16. Therefore, when the user attaches the silver crystal unit 15, it is possible to prevent the silver crystal unit 15 from being attached in the wrong direction. The positioning structure provided in the silver crystal unit 15 does not have to be the screw boss portion 23.

　銀クリスタルユニット１５は、主に、銀クリスタル２９（後述、図３参照）と、銀クリスタル２９を収容する収納ケース１８と、収納ケース蓋１９と、で構成されている。 The silver crystal unit 15 is mainly composed of a silver crystal 29 (described later, see FIG. 3), a storage case 18 for accommodating the silver crystal 29, and a storage case lid 19.
　銀クリスタル２９は、水溶性の三酸化二硼素（Ｂ２Ｏ３）に抗菌作用を有する銀成分を練り込んだ材料により構成されており、粒状の多数の小片に形成されている。銀クリスタル２９は、粒状に構成されたことにより、表面積が大きく水に溶解しやすくなっている。銀クリスタル２９は、水に浸漬されることで溶出され、抗菌性の銀イオンを水中に放出する。このように、銀クリスタル２９は、銀イオン水を生成して洗濯物に抗菌作用を付与する補助剤として働く。 The silver crystal 29 is composed of a material in which a silver component having an antibacterial action is kneaded into water-soluble diboron trioxide (B2O3), and is formed into a large number of granular small pieces. Since the silver crystal 29 is composed of particles, it has a large surface area and is easily dissolved in water. The silver crystal 29 is eluted by immersion in water and releases antibacterial silver ions into the water. In this way, the silver crystal 29 acts as an auxiliary agent that produces silver ionized water and imparts an antibacterial effect to the laundry.
　収納ケース１８は、上方が開口する箱状に形成されており、収納ケース蓋１９により上方を覆われている。収納ケース蓋１９は、屈曲可能に構成されたヒンジ部２２により収納ケース１８と接続されている。 The storage case 18 is formed in a box shape with an upper opening, and is covered above by a storage case lid 19. The storage case lid 19 is connected to the storage case 18 by a hinge portion 22 configured to be bendable.
　収納ケース蓋１９には、側面外側に嵌合ツメ凸部２５が設けられている。一方、収納ケース１８の開口付近の側面内側には、嵌合ツメ凸部２５と対向する位置に嵌合ツメ凹部２６が設けられている。これらの構成により、収納ケース蓋１９を閉めた状態で、嵌合ツメ凸部２５と嵌合ツメ凹部２６が係合して収納ケース蓋１９は、収納ケース１８に仮固定される。 The storage case lid 19 is provided with a fitting claw convex portion 25 on the outer side surface. On the other hand, on the inside of the side surface near the opening of the storage case 18, a fitting claw recess 26 is provided at a position facing the fitting claw convex portion 25. With these configurations, with the storage case lid 19 closed, the fitting claw convex portion 25 and the fitting claw concave portion 26 are engaged with each other, and the storage case lid 19 is temporarily fixed to the storage case 18.
　収納ケース蓋１９は、側方に突出して配置され、下方に延伸するネジボス部２３が形成されている。ネジボス部２３およびネジ座部２４は、ヒンジ部２２の対向側に配置されている。ネジボス部２３には、下方からネジ止めするためにネジ穴２３ａが形成されている。収納ケース蓋１９は、収納ケース１８に仮固定された状態で、ネジ２４ａによりネジ座部２４とネジボス部２３においてネジ止めされている。 The storage case lid 19 is arranged so as to project laterally, and a screw boss portion 23 extending downward is formed. The screw boss portion 23 and the screw seat portion 24 are arranged on opposite sides of the hinge portion 22. A screw hole 23a is formed in the screw boss portion 23 for screwing from below. The storage case lid 19 is temporarily fixed to the storage case 18 and is screwed to the screw seat portion 24 and the screw boss portion 23 by screws 24a.
　このように、収納ケース蓋１９が閉じた状態では、嵌合ツメ凸部２５と嵌合ツメ凹部２６が係合して仮固定されるため、ネジ２４ａをネジボス部２３のネジ穴２３ａに対してネジ止め作業する際に、収納ケース蓋１９が自然に開くことを抑制できる。そのため、収納ケース１８に銀クリスタル２９を入れる際の作業性がよい。 In this way, when the storage case lid 19 is closed, the fitting claw convex portion 25 and the fitting claw concave portion 26 are engaged and temporarily fixed, so that the screw 24a is attached to the screw hole 23a of the screw boss portion 23. It is possible to prevent the storage case lid 19 from opening naturally during the screwing operation. Therefore, the workability when putting the silver crystal 29 in the storage case 18 is good.

FIG. 8B is a cross-sectional view taken along the line 8B-8B of FIG. 8A. FIG. 8C is a cross-sectional view taken along the line 8C-8C of FIG. 8A. FIG. 9A is a top view of the silver crystal unit of the washing machine according to the first embodiment. FIG. 9B is a bottom view of the silver crystal unit of the washing machine according to the first embodiment. 9C is a cross-sectional view taken along the line 9C-9C of FIG. 9A.
　収納ケース蓋１９には、銀クリスタルユニット１５の内部に水を導入する第１開口部２０が設けられており、収納ケース１８の底面である収納ケース底面２８には、水を排出する第２開口部２１が設けられている。これにより、銀クリスタルユニット１５は、導入された水が銀クリスタル２９に浸漬することにより生成された銀イオン水を、第２開口部２１から下方に吐出する。 The storage case lid 19 is provided with a first opening 20 for introducing water inside the silver crystal unit 15, and a second opening for discharging water is provided on the bottom surface 28 of the storage case, which is the bottom surface of the storage case 18. A unit 21 is provided. As a result, the silver crystal unit 15 discharges the silver ionized water generated by immersing the introduced water in the silver crystal 29 downward from the second opening 21.
　第２開口部２１は、第１開口部２０の鉛直下方とならないように配置されており、かつ第１開口部２０よりも開口面積が大きくなるように構成されている。第１開口部２０は、収納ケース蓋１９において略中央よりも端側に配置されており、一部分が第２開口部２１と重なる。 The second opening 21 is arranged so as not to be vertically below the first opening 20, and is configured so that the opening area is larger than that of the first opening 20. The first opening 20 is arranged on the end side of the storage case lid 19 from substantially the center, and a part thereof overlaps with the second opening 21.
　また、収納ケース１８の収納ケース底面２８は、下方に傾斜して形成されている。これにより、内部の銀クリスタル２９は、自重により下方に移動し、傾斜の下部に溜まりやすくなっている。 Further, the storage case bottom surface 28 of the storage case 18 is formed so as to be inclined downward. As a result, the silver crystal 29 inside moves downward due to its own weight, and tends to accumulate at the lower part of the slope.
　図９Ｃに示すように、第１開口部２０および第２開口部２１は、その開口部分を通水部材２７が覆うように、通水部材２７とインサート成形により一体成型されている。通水部材２７は、収納ケース１８とは異なる素材で構成されており、目が約１００メッシュ程度となるように網目状に形成されている。これにより、通水部材２７は、水を通過させるとともに、一定以上の大きさの銀クリスタル２９を通過させない。また、銀クリスタル２９は、水に溶解するに従って徐々に小さくなり、通水部材２７の目を通るサイズまで溶解した銀クリスタル２９の粒は、使用者に視認されない。 As shown in FIG. 9C, the first opening 20 and the second opening 21 are integrally molded with the water passing member 27 by insert molding so that the opening portion is covered by the water passing member 27. The water flow member 27 is made of a material different from that of the storage case 18, and is formed in a mesh shape so that the mesh size is about 100 mesh. As a result, the water passage member 27 allows water to pass through and does not allow the silver crystal 29 having a certain size or larger to pass through. Further, the silver crystal 29 gradually becomes smaller as it dissolves in water, and the grains of the silver crystal 29 dissolved to a size that allows the water passage member 27 to pass through the eyes are not visible to the user.
　以上のように構成された洗濯機および銀イオン溶出装置について、以下その動作、作用を説明する。 The operation and operation of the washing machine and the silver ion elution device configured as described above will be described below.
　（洗濯運転）
　使用者は、蓋体６を開いて洗濯兼脱水槽３に衣類を投入し、操作表示部３１を操作して運転内容を設定し、制御装置７に洗濯運転を開始させる。使用者は、衣類の量に応じた量の粉洗剤または液体洗剤を洗剤ケース９に投入する。 (Washing operation)
The user opens the lid 6 to put clothes into the washing / dehydrating tub 3, operates the operation display unit 31 to set the operation content, and causes the control device 7 to start the washing operation. The user puts an amount of powder detergent or liquid detergent according to the amount of clothes into the detergent case 9.
　洗い行程が開始すると、制御装置７は、第１の給水弁８１を開放して粉洗剤用投入部用の給水口８ａおよび液体洗剤投入部用の給水口８ｂを介して注水装置１１に水を導入し、注水装置１１は、洗剤用ノズル１３の粉洗剤用ノズル１３ａおよび液体洗剤用ノズル１３ｂを介して、粉洗剤投入部９ａおよび液体洗剤投入部９ｂに注水する。洗剤ケース９内の洗剤は、水に溶解されて洗剤ケース収容部１２へ排出され、水と共に水槽４および洗濯兼脱水槽３に投入される。制御装置７は、所定の量の水が給水されると第１の給水弁８１を閉じ、洗濯兼脱水槽３内に収容された衣類をパルセータ５により攪拌させて洗い攪拌を行う。洗い行程が完了すると、すすぎ行程が開始する。 When the washing process starts, the control device 7 opens the first water supply valve 81 to supply water to the water injection device 11 via the water supply port 8a for the powder detergent inlet and the water inlet 8b for the liquid detergent inlet. Introduced, the water injection device 11 injects water into the powder detergent charging unit 9a and the liquid detergent charging unit 9b via the detergent nozzle 13a and the liquid detergent nozzle 13b of the detergent nozzle 13. The detergent in the detergent case 9 is dissolved in water, discharged to the detergent case accommodating portion 12, and put into the water tank 4 and the washing / dehydrating tank 3 together with water. When a predetermined amount of water is supplied, the control device 7 closes the first water supply valve 81, and the clothes housed in the washing / dehydrating tank 3 are stirred by the pulsator 5 to wash and stir. When the washing process is complete, the rinsing process begins.
　すすぎ行程が開始すると、最初のすすぎ動作が開始する。なお、最初のすすぎ動作は、複数回行ってもよい。最初のすすぎ動作では、第１の給水弁８１を開放して空の粉洗剤投入部９ａおよび液体洗剤投入部９ｂに注水し、柔軟剤および銀イオンを含まない水を水槽４および洗濯兼脱水槽３に供給する。続いて、パルセータ５による衣類の攪拌が開始し、衣類に付着した洗剤の成分を洗い流す。 When the rinsing process started, the first rinsing operation started. The first rinsing operation may be performed a plurality of times. In the first rinsing operation, the first water supply valve 81 is opened to inject water into the empty powder detergent charging section 9a and the liquid detergent charging section 9b, and water containing no softener and silver ions is poured into the water tank 4 and the washing / dehydrating tank. Supply to 3. Subsequently, the pulsator 5 starts stirring the clothes to wash away the detergent components adhering to the clothes.
　制御装置７は、注水装置１１に柔軟剤投入部９ｃおよび銀クリスタルユニット収容部１６に給水させるため、第２の給水弁８２を開放して柔軟剤用ノズル１４および銀クリスタル用ノズル１０に水を供給する。柔軟剤用ノズル１４から下方に放出された水は、柔軟剤投入部９ｃに投入された柔軟剤を溶解し、サイフォン構造３０ｂにより運搬されて洗剤ケース収容部１２に排出される。銀クリスタル用ノズル１０から下方に放出された水は、後述するように銀クリスタルユニット１５を通って銀イオン水となり、洗剤ケース収容部１２に排出される。洗剤ケース収容部１２に排出された柔軟剤および銀イオンを含む水は、水槽４および洗濯兼脱水槽３に投入される。続いて、パルセータ５による衣類の攪拌が開始し、衣類に柔軟剤および銀イオンを付着させる。最終のすすぎ動作が終了すると共にすすぎ行程が完了する。 In the control device 7, the second water supply valve 82 is opened to supply water to the softener nozzle 14 and the silver crystal nozzle 10 in order for the water injection device 11 to supply water to the softener charging section 9c and the silver crystal unit accommodating section 16. Supply. The water discharged downward from the softener nozzle 14 dissolves the softener charged into the softener charging unit 9c, is carried by the siphon structure 30b, and is discharged to the detergent case accommodating unit 12. The water discharged downward from the silver crystal nozzle 10 passes through the silver crystal unit 15 to become silver ion water, which is discharged to the detergent case accommodating portion 12. The water containing the softener and silver ions discharged into the detergent case accommodating portion 12 is charged into the water tank 4 and the washing / dehydrating tank 3. Subsequently, the pulsator 5 starts stirring the garment to attach the softener and silver ions to the garment. The rinsing process is completed as soon as the final rinsing operation is completed.
　銀イオンは、陽イオンであるので、マイナスに分極する分子構造を含む一般的な衣類に対して付着しやすいという性質がある。しかしながら、陰イオン界面活性剤を含む洗剤と同時に投入した場合には、銀イオンと陰イオン界面活性剤との間に相互作用が働くため、衣類に付着する銀イオンの量が減少する。 Since silver ions are cations, they have the property of easily adhering to general clothing containing a negatively polarized molecular structure. However, when the detergent containing the anionic surfactant is added at the same time, the amount of silver ions adhering to the clothes is reduced because the interaction between the silver ions and the anionic surfactant acts.
　一方、本実施の形態のように、陽イオン界面活性剤を含む柔軟剤と同時に投入した場合には、相乗効果が働き、衣類に強固に付着させることができる。従って、注水装置１１に柔軟剤投入部９ｃおよび銀クリスタルユニット収容部１６に給水させることにより、銀イオンによる抗菌作用を効率よく得ることができる。 On the other hand, when a softener containing a cationic surfactant is added at the same time as in the present embodiment, a synergistic effect is exerted and the fabric can be firmly adhered to clothing. Therefore, by supplying water to the softener charging section 9c and the silver crystal unit accommodating section 16 in the water injection device 11, the antibacterial action of silver ions can be efficiently obtained.
　（銀クリスタルユニット周囲の動作）
　図１０は、第１の実施の形態における洗濯機の洗剤ケース周囲の縦断面における銀クリスタルユニットに流れ込む水の流れを示す模式図である。図１１は、第１の実施の形態における洗濯機の洗剤ケース周囲の横断面における銀クリスタルユニットに流れ込む水の流れを示す模式図である。 (Movement around the silver crystal unit)
FIG. 10 is a schematic view showing the flow of water flowing into the silver crystal unit in the vertical cross section around the detergent case of the washing machine according to the first embodiment. FIG. 11 is a schematic view showing the flow of water flowing into the silver crystal unit in the cross section around the detergent case of the washing machine according to the first embodiment.
　第２の給水弁８２が開放されると、注水装置１１の内部に水が導入される。注水装置１１に導入された水は、銀クリスタル用ノズル１０である第１のノズル１０ａおよび第２のノズル１０ｂから下方に放出され、通水部材２７を通って銀クリスタルユニット１５に供給される。 When the second water supply valve 82 is opened, water is introduced into the water injection device 11. The water introduced into the water injection device 11 is discharged downward from the first nozzle 10a and the second nozzle 10b, which are the silver crystal nozzles 10, and is supplied to the silver crystal unit 15 through the water passing member 27.
　図１１に示すように、銀クリスタル用ノズル１０は、径の小さな孔として形成されている。一般的に、孔から放出された水は、孔から離れるに従って水流の幅が徐々に広がっていく。 As shown in FIG. 11, the silver crystal nozzle 10 is formed as a hole having a small diameter. In general, the water discharged from the pores gradually widens as the distance from the pores increases.
　銀クリスタルユニット１５は、通水部材２７と銀クリスタル用ノズル１０との距離が近くなるように構成されている。これにより、銀クリスタル用ノズル１０から放出された水は、水流の幅が広がるよりも早く通水部材２７に到達する。幅の狭い水流は、通水部材２７の細かい目を通過できるので、勢いを保ったまま銀クリスタルユニット１５内へ効率よく供給されることができる。 The silver crystal unit 15 is configured such that the water flow member 27 and the silver crystal nozzle 10 are close to each other. As a result, the water discharged from the silver crystal nozzle 10 reaches the water flow member 27 earlier than the width of the water flow widens. Since the narrow water flow can pass through the fine mesh of the water passing member 27, it can be efficiently supplied into the silver crystal unit 15 while maintaining the momentum.
　図１０に示すように、径が大きい第１のノズル１０ａおよび径が小さい第２のノズル１０ｂから注水された水は、収納ケース１８内で乱流を発生させる。乱流となった水は、銀クリスタル２９を水に満遍なく浸漬させるため、高濃度の銀イオン水となる。また、注水の度に、銀クリスタル２９全体が均一に水に晒されるため、毎回の洗濯運転において銀イオン水の濃度を一定に保つことができる。 As shown in FIG. 10, the water injected from the first nozzle 10a having a large diameter and the second nozzle 10b having a small diameter causes turbulence in the storage case 18. The turbulent water becomes high-concentration silver ion water because the silver crystal 29 is evenly immersed in the water. Further, since the entire silver crystal 29 is uniformly exposed to water each time water is injected, the concentration of silver ionized water can be kept constant in each washing operation.
　図１１に示すように、粒状である銀クリスタル２９は、水流により収納ケース１８の内部で動かされる。これにより、銀クリスタル２９は、水と満遍なく接触するとともに、他の銀クリスタル２９の粒または収納ケース１８の内壁と擦れ合って、速やかに水に溶解する。このように、銀クリスタル２９間で間隙を有するように、粒状の銀クリスタル２９を収納ケース１８に充填することで、銀クリスタル２９を素早く水に溶解させることができる。 As shown in FIG. 11, the granular silver crystal 29 is moved inside the storage case 18 by a stream of water. As a result, the silver crystal 29 comes into even contact with water and rubs against other silver crystal 29 grains or the inner wall of the storage case 18 to quickly dissolve in water. In this way, by filling the storage case 18 with the granular silver crystals 29 so as to have a gap between the silver crystals 29, the silver crystals 29 can be quickly dissolved in water.
　更に、第１開口部２０から銀クリスタルユニット１５内に導入された水は、直線的に下降するのではなく、収納ケース１８の内部を迂回して流下して第２開口部２１へ到達する。このように、第１開口部２０の鉛直下方とならないように第２開口部２１を配置したことにより、収納ケース１８の縦寸法よりも長い距離にわたって銀クリスタル２９と水を接触させることができる。この作用により、水を銀クリスタル２９全体に満遍なく接触させることができるので、洗濯運転の度に、安定して高濃度の銀イオン水を生成できる。 Further, the water introduced into the silver crystal unit 15 from the first opening 20 does not descend linearly, but bypasses the inside of the storage case 18 and flows down to reach the second opening 21. By arranging the second opening 21 so as not to be vertically below the first opening 20 in this way, the silver crystal 29 and water can be brought into contact with each other over a distance longer than the vertical dimension of the storage case 18. By this action, water can be evenly contacted with the entire silver crystal 29, so that high-concentration silver ion water can be stably generated every time the washing operation is performed.
　図１１に示すように、銀クリスタルユニット１５内で生成された銀イオン水は、第２開口部２１から排出される。本実施の形態では、第２開口部２１を第１開口部２０より大きく設けることにより、給水量が排水量を上回ることを抑制し、銀クリスタルユニット１５の上部から水が溢れることを抑制している。 As shown in FIG. 11, the silver ionized water generated in the silver crystal unit 15 is discharged from the second opening 21. In the present embodiment, the second opening 21 is provided larger than the first opening 20 to prevent the amount of water supplied from exceeding the amount of drainage and to prevent water from overflowing from the upper part of the silver crystal unit 15. ..
　（銀クリスタルの減少、銀クリスタルユニットの交換）
　図１２Ａは、第１の実施の形態における洗濯機の銀クリスタルユニットの銀クリスタルが重点状態である図９Ａの１２Ａ－１２Ａ断面図である。図１２Ｂは、第１の実施の形態における洗濯機の銀クリスタルユニットの銀クリスタルが残り少量である状態の図９Ａの１２Ｂ－１２Ｂ断面図である。 (Reduction of silver crystals, replacement of silver crystal units)
FIG. 12A is a cross-sectional view taken along the line 12A-12A of FIG. 9A in which the silver crystal of the silver crystal unit of the washing machine according to the first embodiment is in a focused state. FIG. 12B is a cross-sectional view taken along the line 12B-12B of FIG. 9A in a state where the silver crystal of the silver crystal unit of the washing machine according to the first embodiment is a small amount remaining.
　銀クリスタル２９は水溶性であるため、洗濯運転を実行する度に徐々に減少する。図１２Ａおよび図１２Ｂに示すように、収納ケース１８の収納ケース底面２８が傾斜しているので、残りが少量となった銀クリスタル２９は傾斜の下部に溜まりやすくなっている。また、図１０に示すように、収納ケース１８の収納ケース底面２８は、放水量の多い第１のノズル１０ａが配置されている向きに下方傾斜しているため、残りが少量の銀クリスタル２９を効率よく水に溶解させることができる。 Since silver crystal 29 is water-soluble, it gradually decreases every time the washing operation is performed. As shown in FIGS. 12A and 12B, since the bottom surface 28 of the storage case 18 of the storage case 18 is inclined, the silver crystal 29 having a small amount of remaining is likely to accumulate at the lower part of the inclination. Further, as shown in FIG. 10, since the bottom surface 28 of the storage case of the storage case 18 is inclined downward in the direction in which the first nozzle 10a having a large amount of water discharged is arranged, a small amount of silver crystal 29 remains. It can be efficiently dissolved in water.
　銀イオンの溶出が進むに従って、銀クリスタル２９の量は徐々に減少していき、銀クリスタル２９の量が一定以下まで減少すると洗濯衣類に対する抗菌効果も低下する。従って、使用者は、適切なタイミングで銀クリスタルユニット１５を新しい物に交換することで、洗濯機の抗菌性能を保つことができる。 As the elution of silver ions progresses, the amount of silver crystals 29 gradually decreases, and when the amount of silver crystals 29 decreases below a certain level, the antibacterial effect on laundry clothes also decreases. Therefore, the user can maintain the antibacterial performance of the washing machine by replacing the silver crystal unit 15 with a new one at an appropriate timing.
　銀クリスタル２９の減少量は、洗濯運転の実行回数と相関があるので、銀クリスタルユニット１５の交換推奨洗濯回数は、実験的に求められる。本実施の形態における洗濯機は、制御装置７が洗濯運転の実行回数を測定し、実行回数が交換推奨洗濯回数に到達すると操作表示部３１のＬＥＤ（図示せず）を点滅させる。これにより、使用者は、銀クリスタルユニット１５の内部を目視せずに銀クリスタル２９の残量を確認できるため、銀クリスタルユニット１５の内部を視認可能に構成した窓を設けずに済む。 Since the amount of decrease in the silver crystal 29 correlates with the number of times the washing operation is executed, the recommended number of times the silver crystal unit 15 is replaced is experimentally obtained. In the washing machine according to the present embodiment, the control device 7 measures the number of times the washing operation is executed, and when the number of times the washing operation is executed reaches the recommended number of times for replacement, the LED (not shown) of the operation display unit 31 blinks. As a result, the user can check the remaining amount of the silver crystal 29 without visually observing the inside of the silver crystal unit 15, so that it is not necessary to provide a window configured so that the inside of the silver crystal unit 15 can be visually recognized.
　また、操作表示部において、銀クリスタルユニット１５の残り使用可能回数を報知してもよい。これにより、使用者は、銀クリスタルユニット１５の交換時期を早めに把握できるので、交換用の銀クリスタルユニット１５を前以て準備することができる。 Further, the operation display unit may notify the remaining usable number of times of the silver crystal unit 15. As a result, the user can grasp the replacement time of the silver crystal unit 15 early, so that the replacement silver crystal unit 15 can be prepared in advance.
　（作用等）
　以上のように、本実施の形態における洗濯機は、銀クリスタル２９を収容した銀クリスタルユニット１５と、銀クリスタルユニット１５を脱着可能に収容する銀クリスタルユニット収容部１６が設けられた洗剤ケース９と、銀クリスタルユニット１５に給水する注水装置１１と、を備える。 (Action, etc.)
As described above, the washing machine according to the present embodiment includes a silver crystal unit 15 accommodating the silver crystal 29 and a detergent case 9 provided with a silver crystal unit accommodating portion 16 accommodating the silver crystal unit 15 in a detachable manner. , A water injection device 11 for supplying water to the silver crystal unit 15.
　この構成により、銀クリスタル２９の残量が少なくなった場合、銀クリスタルユニット１５を交換できる。また、必要に応じて、銀クリスタルユニット１５を外して洗濯運転できる。 With this configuration, when the remaining amount of silver crystal 29 is low, the silver crystal unit 15 can be replaced. Further, if necessary, the silver crystal unit 15 can be removed for washing operation.
　本実施の形態のように、銀クリスタルユニット収容部１６には、銀クリスタルユニット１５を挿入方向に案内する傾斜リブ１６ｃが形成されていてもよい。 As in the present embodiment, the silver crystal unit accommodating portion 16 may be formed with an inclined rib 16c that guides the silver crystal unit 15 in the insertion direction.
　この構成により、傾斜リブ１６ｃが銀クリスタルユニット１５を挿入方向に案内するため、滑らかな挿入が可能である。また、銀クリスタルユニット１５と銀クリスタルユニット収容部１６との接触面積が小さくなるため、挿入の際の摩擦を減らすことができる。 With this configuration, the inclined rib 16c guides the silver crystal unit 15 in the insertion direction, so that smooth insertion is possible. Further, since the contact area between the silver crystal unit 15 and the silver crystal unit accommodating portion 16 becomes small, friction at the time of insertion can be reduced.
　本実施の形態のように、銀クリスタルユニット１５の上部にはヒンジ部２２が設けられており、銀クリスタルユニット１５が銀クリスタルユニット収容部１６に挿入されることにより、ヒンジ部２２は、銀クリスタルユニット収容部側ツメ１６ｂに係って止められてもよい。 As in the present embodiment, a hinge portion 22 is provided on the upper portion of the silver crystal unit 15, and when the silver crystal unit 15 is inserted into the silver crystal unit accommodating portion 16, the hinge portion 22 becomes a silver crystal. It may be stopped by the claw 16b on the unit accommodating portion side.
　この構成により、銀クリスタルユニット１５は、銀クリスタルユニット収容部１６に装着された状態になり、洗剤ケース９が逆さにされた場合でも落下しない。 With this configuration, the silver crystal unit 15 is attached to the silver crystal unit accommodating portion 16 and does not fall even when the detergent case 9 is turned upside down.
　本実施の形態のように、銀クリスタルユニット１５は、収納ケース１８と、銀クリスタル２９と、を備え、収納ケース１８は、銀クリスタル２９を収容する本体部と、本体部の上面を覆う収納ケース蓋１９と、を含む。収納ケース蓋１９には、本体部に対して下方から、ネジ２４ａにてネジ止めされるネジボス部２３に設けたネジ穴２３ａが形成されていてもよい。 As in the present embodiment, the silver crystal unit 15 includes a storage case 18 and a silver crystal 29, and the storage case 18 includes a main body for accommodating the silver crystal 29 and a storage case that covers the upper surface of the main body. Includes a lid 19 and. The storage case lid 19 may be formed with a screw hole 23a provided in the screw boss portion 23 screwed with a screw 24a from below with respect to the main body portion.
　この構成により、下方からネジ止めすることにより、ネジ２４ａが水に触れにくい構造となっている。 With this configuration, the screw 24a is hard to come into contact with water by screwing from below.
　そのため、ネジ２４ａが錆びることを抑制できる。 Therefore, it is possible to prevent the screw 24a from rusting.
　本実施の形態のように、収納ケース１８は、屈曲可能に設けられ、本体部と収納ケース蓋１９とを連結するヒンジ部２２を含み、本体部、収納ケース蓋１９およびヒンジ部２２は、一体的に形成されていてもよい。 As in the present embodiment, the storage case 18 is provided so as to be bendable, includes a hinge portion 22 for connecting the main body portion and the storage case lid 19, and the main body portion, the storage case lid 19 and the hinge portion 22 are integrated. It may be formed as a target.
　この構成により、一体部品とすることで部品点数が削減できる。 With this configuration, the number of parts can be reduced by making them integrated parts.
