Description

本発明は、洗浄効果を高めうる洗濯装置に関する。 The present invention relates to a washing device capable of enhancing the washing effect.

近年、水を電気分解して得られる水素水（アルカリ性水）を、洗濯用の水として用いることが提案されている。この水素水は、衣服の汚れである皮脂などの油汚れを膨潤して乳化分解させる効果を有する。そのため、洗浄効果を高めるとともに、洗剤の使用量の削減を図ることが可能になる。また水素水中に含まれる水素ガスの気泡が、分解された汚れに付着して浮き上がらせる所謂ローリングアップ効果を発揮し、洗浄効果をさらに向上させうる。 In recent years, it has been proposed to use hydrogen water (alkaline water) obtained by electrolyzing water as washing water. This hydrogen water has the effect of swelling and emulsifying and decomposing oil stains such as sebum, which are stains on clothes. Therefore, it is possible to enhance the cleaning effect and reduce the amount of detergent used. In addition, bubbles of hydrogen gas contained in hydrogen water adhere to the decomposed dirt and float up, so that the so-called rolling-up effect can be exerted, and the cleaning effect can be further improved.

しかし、水を電気分解して得られた水素水には、電解用電極に析出するカルシウムイオンやマグネシウムイオンなどの物質の一部が混在する。そのため、このような水素水を洗濯用の水として使用した場合、前記物質が、汚れの乳化分解を阻害し、洗浄効果が十分に発揮されないという問題がある。 However, hydrogen water obtained by electrolyzing water contains some substances such as calcium ions and magnesium ions that are deposited on the electrodes for electrolysis. Therefore, when such hydrogen water is used as washing water, there is a problem that the substance inhibits the emulsification and decomposition of dirt and the cleaning effect is not sufficiently exhibited.

そこで、下記の特許文献１には、水を電気分解することで得られるアルカリ性の軟水を、洗濯用水として洗濯槽に供給する洗濯機が提案されている。 Therefore, Patent Document 1 below proposes a washing machine that supplies alkaline soft water obtained by electrolyzing water to a washing tub as washing water.

具体的には、前記提案の洗濯機は、洗濯槽に水を供給する給水路と、前記給水路にナトリウム型陽イオン交換樹脂を充填した軟水化手段と、少なくとも一対の電極を有し内部を隔膜で分離形成した電解槽とを有する。この洗濯槽では、前記軟水化手段により、水中のカルシウムおよびマグネシウム等の硬度成分をナトリウムにイオン交換し、硬度成分を除去して軟水化した水を、電解槽により電気分解している。そのため、生成されるアルカリ性水に、カルシウムイオンやマグネシウムイオンなどの物質が混在するのを抑制でき、洗浄能力の低下を抑えうる。 Specifically, the proposed washing machine has at least a pair of electrodes, a water supply channel for supplying water to the washing tub, a water softening means in which the water supply channel is filled with a sodium-type cation exchange resin, and the inside thereof. It has an electrolytic cell separated and formed by a diaphragm. In this washing tub, hardness components such as calcium and magnesium in water are ion-exchanged with sodium by the water softening means, and water softened by removing the hardness components is electrolyzed by an electrolytic cell. Therefore, it is possible to suppress the mixture of substances such as calcium ions and magnesium ions in the generated alkaline water, and it is possible to suppress a decrease in cleaning ability.

特開２００６−４３１０１号公報Japanese Unexamined Patent Publication No. 2006-43101

しかし、上記提案の洗濯機は、軟水化手段を必要とするため、コストの上昇やメンテナンス性の低下を招く。また、アルカリ性水の水素濃度は、洗濯中の水流などにより徐々に減じる傾向にある。しかし、上記提案の洗濯機では、生成したアルカリ性水を洗濯槽に供給するため、洗濯中に低下する水素濃度を補うことができず、洗浄効果において、さらなる改善が望まれる。 However, since the washing machine proposed above requires a water softening means, it causes an increase in cost and a decrease in maintainability. In addition, the hydrogen concentration of alkaline water tends to gradually decrease due to the water flow during washing. However, in the washing machine proposed above, since the generated alkaline water is supplied to the washing tub, it is not possible to compensate for the hydrogen concentration that decreases during washing, and further improvement in the washing effect is desired.

そこで発明は、コストの上昇やメンテナンス性の低下を抑えるとともに、洗濯中の水素濃度の低下を補うことが可能であり、洗浄効果の向上に貢献しうる洗濯装置を提供することを課題としている。 Therefore, it is an object of the present invention to provide a washing apparatus capable of suppressing an increase in cost and a decrease in maintainability and compensating for a decrease in hydrogen concentration during washing and contributing to an improvement in cleaning effect.

Includes a third flow path with a gas outlet.

本発明に係る洗濯装置において、前記第３流路は、前記洗濯槽内の前記洗濯用水が、前記電解槽の側に逆流するのを阻止する一方弁を具えるのが好ましい。 In the washing apparatus according to the present invention, it is preferable that the third flow path is provided with a one-sided valve that prevents the washing water in the washing tub from flowing back to the side of the electrolytic cell.

本発明に係る洗濯装置において、前記電解槽で発生する前記酸素ガスを、前記洗濯槽の前記洗濯用水中に放出させる酸素ガス放出口を有する第４流路をさらに含むのが好ましい。 In the washing apparatus according to the present invention, it is preferable to further include a fourth flow path having an oxygen gas discharge port for discharging the oxygen gas generated in the electrolytic cell into the washing water of the washing tub.

本発明に係る洗濯装置において、前記第４流路は、前記洗濯槽内の前記洗濯用水が、前記電解槽の側に逆流するのを阻止する一方弁を具えるのが好ましい。 In the washing apparatus according to the present invention, it is preferable that the fourth flow path is provided with a one-sided valve that prevents the washing water in the washing tub from flowing back to the side of the electrolytic cell.

本発明に係る洗濯装置において、前記洗濯槽は、外槽部と、前記外槽部内で回転可能に支持される内槽部とを有し、前記外槽部と前記内槽部との間で洗濯用水が通り抜け可能であるのが好ましい。 In the washing apparatus according to the present invention, the washing tub has an outer tub portion and an inner tub portion rotatably supported in the outer tub portion, and is located between the outer tub portion and the inner tub portion. It is preferable that the washing water can pass through.

本発明に係る洗濯装置において、前記水素ガス放出口は、前記外槽部と前記内槽部との間で開口する前記水素ガス放出口は、前記外槽部と前記内槽部との間で開口するのが好ましい。 In the washing apparatus according to the present invention, the hydrogen gas discharge port opens between the outer tank portion and the inner tank portion, and the hydrogen gas discharge port opens between the outer tank portion and the inner tank portion. It is preferable to open it.

本発明に係る洗濯装置において、前記酸素ガス放出口は、前記外槽部と前記内槽部との間で開口するのが好ましい。 In the washing apparatus according to the present invention, it is preferable that the oxygen gas discharge port is opened between the outer tank portion and the inner tank portion.

本発明に係る洗濯装置において、前記酸素ガス放出口には、前記洗濯用水の上面を越えて上方にのび、前記酸素ガスを前記洗濯槽外に排出する排出管が配されるのが好ましい。 In the washing apparatus according to the present invention, it is preferable that the oxygen gas discharge port is provided with a discharge pipe that extends upward beyond the upper surface of the washing water and discharges the oxygen gas to the outside of the washing tub.

本発明に係る洗濯装置において、前記電解手段は、洗濯中にも電気分解し、前記水素ガスを、洗濯中の前記洗濯用水中に放出させうるのが好ましい。 In the washing apparatus according to the present invention, it is preferable that the electrolytic means can be electrolyzed during washing and the hydrogen gas can be released into the washing water during washing.

本発明の洗濯装置では、電解槽で発生する水素ガスを、第３流路の水素ガス放出口から洗濯槽の洗濯用水中に放出させることにより、水素ガスが洗濯用水に溶解する。これにより、水素水を洗濯槽内で直接に生成しうる。 In the washing apparatus of the present invention, the hydrogen gas is dissolved in the washing water by discharging the hydrogen gas generated in the electrolytic cell into the washing water of the washing tub from the hydrogen gas discharge port of the third flow path. This allows hydrogen water to be produced directly in the washing tub.

すなわち、従来のような、電気分解によって生成された水素水（アルカリ性）を、洗濯槽に供給するものと相違するため、カルシウムイオンやマグネシウムイオンなどの物質が、洗濯用水に混在するのを抑制しうる。そのため、前記物質に起因する洗浄能力の低下を抑えうる。またイオン交換樹脂を用いた軟水化手段が不要となるため、コストの上昇やメンテナンス性の低下を抑えうる。 That is, it is different from the conventional method of supplying hydrogen water (alkaline) generated by electrolysis to the washing tub, so that substances such as calcium ions and magnesium ions are suppressed from being mixed in the washing water. sell. Therefore, it is possible to suppress a decrease in cleaning ability due to the substance. Further, since the water softening means using the ion exchange resin is not required, it is possible to suppress an increase in cost and a decrease in maintainability.

しかも、水素ガスを供給するため、洗濯中における水素濃度の低下を抑えることができ、洗浄効果の維持、或いはさらなる向上を図りうる。 Moreover, since hydrogen gas is supplied, it is possible to suppress a decrease in hydrogen concentration during washing, and it is possible to maintain or further improve the cleaning effect.

本発明の洗濯装置の一実施形態を概念的に示す模式図である。It is a schematic diagram which conceptually shows one Embodiment of the washing apparatus of this invention. 洗濯装置の主要部を拡大して示す模式図である。It is a schematic diagram which shows the main part of a washing apparatus in an enlarged manner.

以下、本発明の実施の形態について、詳細に説明する。
図１に示されるように、本実施形態の洗濯装置１は、洗濯槽２と、電解手段３と、第１流路４と、第２流路５と、第３流路６とを含んで構成される。 Hereinafter, embodiments of the present invention will be described in detail.
As shown in FIG. 1, the washing apparatus 1 of the present embodiment includes a washing tub 2, an electrolytic means 3, a first flow path 4, a second flow path 5, and a third flow path 6. It is composed.

洗濯槽２は、洗濯用水Ｗ１を溜める上開口の水槽であって、筺体８の内部に配される。洗濯用水Ｗ１には、洗剤や柔軟剤などの薬剤を適宜加えることができる。なお洗濯用水Ｗ１は、薬剤が加えられない濯ぎ用の水であっても良い。 The washing tub 2 is a water tub having an upper opening for storing the washing water W1 and is arranged inside the housing 8. Chemicals such as detergents and fabric softeners can be appropriately added to the washing water W1. The washing water W1 may be rinsing water to which no chemical is added.

洗濯槽２の内部には、洗濯用水Ｗ１を撹拌させて洗濯や濯ぎを行うための撹拌羽根９が回転可能に配される。この撹拌羽根９は、洗濯槽２の底部から突出している。撹拌羽根９は、例えば、筺体８或いはそのフレーム等に支持されるモータＭにより、回転駆動される。 Inside the washing tub 2, a stirring blade 9 for stirring the washing water W1 to perform washing and rinsing is rotatably arranged. The stirring blade 9 protrudes from the bottom of the washing tub 2. The stirring blade 9 is rotationally driven by, for example, a motor M supported by a housing 8 or a frame thereof.

本例では、洗濯槽２は、外槽部２ｏと、この外槽部２ｏ内に配される内槽部２ｉとを有し、この内槽部２ｉ内に洗濯物が投入される。内槽部２ｉは、洗濯物を脱水する脱水槽であり、その軸心周りで回転可能に支持される。洗濯槽２では、外槽部２ｏと内槽部２ｉとの間で洗濯用水Ｗ１が通り抜け可能であり、この通り抜けのための複数の貫通孔１７が、内槽部２ｉの周壁部に形成されている。撹拌羽根９は、内槽部２ｉの内部に配され、内槽部２ｉとは独立して回転駆動される。 In this example, the washing tub 2 has an outer tub portion 2o and an inner tub portion 2i arranged in the outer tub portion 2o, and the laundry is put into the inner tub portion 2i. The inner tank portion 2i is a dehydration tank that dehydrates the laundry, and is rotatably supported around the axis thereof. In the washing tub 2, the washing water W1 can pass between the outer tub portion 2o and the inner tub portion 2i, and a plurality of through holes 17 for this passage are formed in the peripheral wall portion of the inner tub portion 2i. There is. The stirring blade 9 is arranged inside the inner tank portion 2i and is rotationally driven independently of the inner tank portion 2i.

外槽部２ｏには、洗濯用水Ｗ１を機外に排出するための排水流路１０が接続されている。この排水流路１０には、洗濯用水Ｗ１を排出する際に開弁する排水弁１１が設けられている。 A drainage channel 10 for discharging the washing water W1 to the outside of the machine is connected to the outer tub portion 2o. The drainage channel 10 is provided with a drainage valve 11 that opens when the washing water W1 is discharged.

図示されないが、筺体８には、外槽部２ｏ及び内槽部２ｉをそれぞれ開閉する蓋体、洗濯装置１の操作や表示を行うための操作パネル、洗濯槽２内に洗剤や柔軟剤などの薬剤を投入するための投入部などを適宜設けることができる。 Although not shown, the housing 8 includes a lid for opening and closing the outer tub 2o and the inner tub 2i, an operation panel for operating and displaying the washing device 1, and a detergent, fabric softener, etc. in the washing tub 2. A charging section or the like for charging the drug can be appropriately provided.

第１流路４は、給水源１２からの水を、洗濯用水Ｗ１として洗濯槽２内に送給する。給水源１２として、本例では、水道の水詮（例えば蛇口）が挙げられる。なお井戸水や地下水などを供給する給水管等の水詮であっても良く、また水道或いは給水管自体であっても良い。 The first flow path 4 supplies the water from the water supply source 12 into the washing tub 2 as washing water W1. As the water supply source 12, in this example, a tap water (for example, a faucet) can be mentioned. It may be a water supply pipe or the like that supplies well water, groundwater, or the like, or it may be a water supply or a water supply pipe itself.

次に、電解手段３は、水を電気分解して水素ガスと酸素ガスとを発生させる電解槽１５を有する。 Next, the electrolytic means 3 has an electrolytic cell 15 that electrolyzes water to generate hydrogen gas and oxygen gas.

図２に拡大して示されるように、電解槽１５内には、第１、第２の電極２１、２２が互いに対向して配されるとともに、第１、第２の電極２１、２２間には隔膜２３が配される。この隔膜２３は、電解槽１５内の電解室１６を、電極２１側の第１の極室１６Ａと電極２２側の第２の極室１６Ｂとに区分する。 As shown enlarged in FIG. 2, the first and second electrodes 21 and 22 are arranged in the electrolytic cell 15 so as to face each other, and between the first and second electrodes 21 and 22. The diaphragm 23 is arranged. The diaphragm 23 divides the electrolytic cell 16 in the electrolytic cell 15 into a first polar chamber 16A on the electrode 21 side and a second polar chamber 16B on the electrode 22 side.

第１、第２の極室１６Ａ、１６Ｂには、それぞれ、給水源１２からの水が電気分解用水Ｗ２として第２流路５を介して送給される。そして第１、第２の電極２１、２２間に直流電圧が印加されることにより。電解室１６内で水の電気分解が生じる。隔膜２３は、電気分解で生じたイオンを通過でき、これにより、陰極側の例えば第１の極室１６Ａから水素ガスが発生し、陽極側の例えば第２の極室１６Ｂから酸素ガスが発生する。隔膜２３に代えて固体高分子電解質膜を用いることもできる。固体高分子電解質膜には、例えば、スルホン酸基を有するフッ素系の樹脂材料からなる固体高分子材料が用いられる。このような固体高分子電解質膜を用いることにより、極室１６Ａ、１６Ｂ内の水が中性に保たれる。 Water from the water supply source 12 is supplied to the first and second polar chambers 16A and 16B as water for electrolysis W2 via the second flow path 5, respectively. Then, a DC voltage is applied between the first and second electrodes 21 and 22. Water electrolysis occurs in the electrolytic chamber 16. The diaphragm 23 can pass ions generated by electrolysis, whereby hydrogen gas is generated from, for example, the first polar chamber 16A on the cathode side, and oxygen gas is generated from, for example, the second polar chamber 16B on the anode side. .. A solid polymer electrolyte membrane can be used instead of the diaphragm 23. For the solid polymer electrolyte membrane, for example, a solid polymer material made of a fluorine-based resin material having a sulfonic acid group is used. By using such a solid polymer electrolyte membrane, the water in the polar chambers 16A and 16B is kept neutral.

ここで、本実施形態の洗濯装置１では、水が電気分解されている間、電解槽１５への電気分解用水Ｗ２の供給は停止されている。これにより、電気分解は、電解室１６内に貯留されている水に対して行われ、電解槽１５からは、水素ガス及び酸素ガスのみが取り出され、水素水及び酸性水は取り出されない。 Here, in the washing apparatus 1 of the present embodiment, the supply of the electrolysis water W2 to the electrolytic cell 15 is stopped while the water is electrolyzed. As a result, the electrolysis is performed on the water stored in the electrolytic cell 16, and only hydrogen gas and oxygen gas are taken out from the electrolytic cell 15, and hydrogen water and acidic water are not taken out.

本例では、給水源１２からのびる一つの共通流路１３が、二つに分岐されており、その分岐流路の一方、他方が第１流路４及び第２流路５を構成する。従って、洗濯用水Ｗ１及び電気分解用水Ｗ２は、給水源１２からの水が分岐したものである。本例では、共通流路１３には、給水源１２からの水を洗濯槽２及び電解槽１５に送給する際にのみ開弁する開閉弁１４が設けられている。 In this example, one common flow path 13 extending from the water supply source 12 is branched into two, and one of the branch flow paths constitutes the first flow path 4 and the second flow path 5. Therefore, the washing water W1 and the electrolysis water W2 are obtained by branching the water from the water supply source 12. In this example, the common flow path 13 is provided with an on-off valve 14 that opens only when the water from the water supply source 12 is supplied to the washing tub 2 and the electrolytic cell 15.

第２流路５は、第１の極室１６Ａに通じる分岐流路部５Ａと、第２の極室１６Ｂに通じる分岐流路部５Ｂとを含む。本例の第２流路５は、前記分岐流路部５Ａ、５Ｂに加え、排水流路１０に通じる接続流路部２４をさらに含む。接続流路部２４には、洗濯が終了し電解槽１５内の電気分解用水Ｗ２を排出する際に開弁する排水弁２５が設けられている。 The second flow path 5 includes a branch flow path portion 5A leading to the first polar chamber 16A and a branch flow path portion 5B leading to the second polar chamber 16B. The second flow path 5 of this example further includes a connection flow path portion 24 leading to the drainage flow path 10 in addition to the branch flow path portions 5A and 5B. The connection flow path portion 24 is provided with a drain valve 25 that opens when washing is completed and the electrolysis water W2 in the electrolytic cell 15 is discharged.

第２流路５は、分岐流路部５Ａ、５Ｂよりも上流側に、一方弁２６を具える。この一方弁２６は、電解槽１５内の電気分解用水Ｗ２が、上流側（給水源１２の側）に逆流するのを防止する。これにより、前記逆流によって電解槽１５内の電気分解用水Ｗ２の貯留量が減じられるのを防止できる。本例では、電解槽１５には、電解室１６の水位低下をさらに抑制するための副貯水部２７が付設される。ここで、電解槽１５では、電気分解にともない電気分解用水Ｗ２の貯留量が次第に低下し、電極２１、２２の一部が露出することで電解効率が低下する恐れを有する。これに対し、副貯水部２７は、電解槽１５における電気分解用水Ｗ２の貯留量を増やし、電解効率の低下を防止しうる。この副貯水部２７は、電解室１６の上部に連設されるのが好ましい。 The second flow path 5 includes a one-sided valve 26 on the upstream side of the branch flow path portions 5A and 5B. On the other hand, the valve 26 prevents the electrolysis water W2 in the electrolytic cell 15 from flowing back to the upstream side (the side of the water supply source 12). As a result, it is possible to prevent the amount of water for electrolysis W2 stored in the electrolytic cell 15 from being reduced due to the backflow. In this example, the electrolytic cell 15 is provided with a sub-water storage unit 27 for further suppressing the decrease in the water level of the electrolytic cell 16. Here, in the electrolytic cell 15, the amount of water for electrolysis W2 stored gradually decreases with electrolysis, and there is a risk that the electrolysis efficiency may decrease due to the exposure of a part of the electrodes 21 and 22. On the other hand, the sub-water storage unit 27 can increase the amount of water for electrolysis W2 stored in the electrolytic cell 15 and prevent a decrease in electrolysis efficiency. It is preferable that the sub-water storage unit 27 is continuously provided in the upper part of the electrolysis chamber 16.

排水流路１０に設けられる前記排水弁１１は、排水流路１０と接続流路部２４との合流点よりも上流側に設けることが好ましい。これにより、洗濯用水Ｗ１の排出とは独立して、電解槽１５内の電気分解用水Ｗ２を排出しうる。また排水弁２５により、洗濯槽２から排出された洗濯用水Ｗ１が電解槽１５側に逆流するのを防止しうる。 The drain valve 11 provided in the drainage flow path 10 is preferably provided on the upstream side of the confluence point between the drainage flow path 10 and the connection flow path portion 24. As a result, the electrolysis water W2 in the electrolytic cell 15 can be discharged independently of the discharge of the washing water W1. Further, the drain valve 25 can prevent the washing water W1 discharged from the washing tub 2 from flowing back to the electrolytic cell 15 side.

第３流路６は、電解槽１５で発生する水素ガスを、洗濯槽２の洗濯用水Ｗ１中に放出させる水素ガス放出口３０を有する。即ち、第３流路６は、電解槽１５（本例では極室１６Ａ）から水素ガス放出口３０まで延びる。 The third flow path 6 has a hydrogen gas discharge port 30 that discharges the hydrogen gas generated in the electrolytic cell 15 into the washing water W1 of the washing tub 2. That is, the third flow path 6 extends from the electrolytic cell 15 (polar chamber 16A in this example) to the hydrogen gas discharge port 30.

水素ガス放出口３０から放出される水素ガスは、洗濯槽２内の洗濯用水Ｗ１に溶解して、洗濯用水Ｗ１を水素水として機能させうる。これにより、皮脂などの汚れを乳化分解させる効果を発揮でき、洗剤と協働して洗浄効果を高めうる。また洗剤の使用量の削減を図ることが可能になる。溶解度を高めるために、撹拌羽根９による洗濯用水Ｗ１の撹拌が有効に機能しうる。 The hydrogen gas released from the hydrogen gas discharge port 30 can be dissolved in the washing water W1 in the washing tub 2 to make the washing water W1 function as hydrogen water. As a result, the effect of emulsifying and decomposing dirt such as sebum can be exhibited, and the cleaning effect can be enhanced in cooperation with the detergent. In addition, it becomes possible to reduce the amount of detergent used. In order to increase the solubility, stirring of the washing water W1 by the stirring blade 9 can function effectively.

さらに本実施形態では、洗濯用水Ｗ１に混在する水素ガスの気泡（バルブ）が、ローリングアップ効果を発揮し、洗浄効果をさらに高めうる。特に、水素ガス自体が洗濯用水Ｗ１中に放出されるため、洗濯用水Ｗ１中の水素ガスの気泡量が多くなり、より高いローリングアップ効果が発揮される。また、濯ぎ中の洗濯用水Ｗ１に水素ガスの気泡が混在されることにより、洗濯物の汚れがより一層除去される。 Further, in the present embodiment, the hydrogen gas bubbles (valves) mixed in the washing water W1 exert a rolling-up effect, and the cleaning effect can be further enhanced. In particular, since the hydrogen gas itself is released into the washing water W1, the amount of bubbles of the hydrogen gas in the washing water W1 increases, and a higher rolling-up effect is exhibited. Further, by mixing hydrogen gas bubbles in the washing water W1 during rinsing, stains on the laundry are further removed.

また従来のような、電気分解によって生成された水素水を、洗濯槽に供給するものと相違するため、カルシウムイオンやマグネシウムイオンなどの物質が、洗濯用水に混在するのを抑制しうる。そのため、前記物質に起因する洗浄能力の低下を抑えうる。またイオン交換樹脂を用いた軟水化手段が不要となるため、コストの上昇やメンテナンス性の低下を抑えうる。 Further, unlike the conventional method of supplying hydrogen water generated by electrolysis to a washing tub, it is possible to prevent substances such as calcium ions and magnesium ions from being mixed in the washing water. Therefore, it is possible to suppress a decrease in cleaning ability due to the substance. Further, since the water softening means using the ion exchange resin is not required, it is possible to suppress an increase in cost and a decrease in maintainability.

また水素ガス自体を供給するため、洗濯中に水素濃度が低下するのを抑えることができ、洗浄効果の維持を図ることが可能になる。また洗濯物の汚れの状態に応じて水素濃度を調整することも可能となる。 Further, since the hydrogen gas itself is supplied, it is possible to suppress a decrease in the hydrogen concentration during washing, and it is possible to maintain the cleaning effect. It is also possible to adjust the hydrogen concentration according to the state of dirt on the laundry.

洗浄効果をさらに高めるために、水素ガス放出口３０に、水素ガスをファインバブル（マイクロバブル、ナノバブルを含む。）化させて洗濯用水Ｗ１に放出するファインバブル発生ノズル（図示省略）を設けることが好ましい。このようなファインバブルは、水素濃度を高める。また繊維間や繊維と汚れとの間にバブルが入りやすくなり、汚れを繊維から分離させる効果を高める。 In order to further enhance the cleaning effect, the hydrogen gas discharge port 30 may be provided with a fine bubble generation nozzle (not shown) that converts hydrogen gas into fine bubbles (including microbubbles and nanobubbles) and discharges them into the washing water W1. preferable. Such fine bubbles increase the hydrogen concentration. In addition, bubbles are likely to enter between fibers and between fibers and dirt, which enhances the effect of separating dirt from fibers.

水素ガス放出口３０は、外槽部２ｏと内槽部２ｉとの間で開口するのが好ましい。これにより、水素ガス放出口３０と洗濯物との接触が防がれ、水素ガス放出口３０が洗濯物と接触することによる損傷、及び水素ガスがバブル化することへの洗濯物による悪影響が抑制される。 The hydrogen gas discharge port 30 is preferably opened between the outer tank portion 2o and the inner tank portion 2i. As a result, the contact between the hydrogen gas discharge port 30 and the laundry is prevented, and the damage caused by the contact between the hydrogen gas discharge port 30 and the laundry and the adverse effect of the laundry on the bubble formation of the hydrogen gas are suppressed. Will be done.

第３流路６には、洗濯槽２内の洗濯用水Ｗ１が、電解槽１５の側に逆流するのを阻止する一方弁３１を具える。これにより、汚れ成分を含む洗濯用水Ｗ１による極室１６Ａ、特に電極２１及び隔膜２３の汚損が防止される。極室１６Ａでの水素ガスの発生に伴い、一方弁３１の両側で生ずる圧力差が大きくなると、水素ガスは一方弁３１を通過して洗濯槽２へと移動する。従って、ポンプ等の送出手段を用いることなく、極室１６Ａで発生した水素ガスを洗濯槽２に送出することが可能となる。 The third flow path 6 is provided with a valve 31 that prevents the washing water W1 in the washing tub 2 from flowing back to the side of the electrolytic cell 15. As a result, the polar chamber 16A, particularly the electrode 21 and the diaphragm 23, are prevented from being soiled by the washing water W1 containing a stain component. When the pressure difference generated on both sides of the one-sided valve 31 increases with the generation of hydrogen gas in the polar chamber 16A, the hydrogen gas passes through the one-sided valve 31 and moves to the washing tub 2. Therefore, the hydrogen gas generated in the polar chamber 16A can be sent to the washing tub 2 without using a sending means such as a pump.

また洗濯装置１は、第４流路７をさらに含む。この第４流路７は、電解槽１５で発生する酸素ガスを、機外に排気する。本例では、第４流路７は、酸素ガスを洗濯槽２の洗濯用水Ｗ１中に放出させる酸素ガス放出口３２を有する。即ち、第４流路７は、電解槽１５（本例では極室１６Ｂ）から酸素ガス放出口３２まで延びる。 Further, the washing apparatus 1 further includes a fourth flow path 7. The fourth flow path 7 exhausts the oxygen gas generated in the electrolytic cell 15 to the outside of the machine. In this example, the fourth flow path 7 has an oxygen gas discharge port 32 that releases oxygen gas into the washing water W1 of the washing tub 2. That is, the fourth flow path 7 extends from the electrolytic cell 15 (polar chamber 16B in this example) to the oxygen gas discharge port 32.

このように、酸素ガスを洗濯用水Ｗ１中に放出させることにより、洗濯装置１の内部、例えばモータ、配管、筺体８の内面などが酸化して早期に腐食劣化するのを抑制しうる。 By releasing the oxygen gas into the washing water W1 in this way, it is possible to prevent the inside of the washing device 1, for example, the motor, the piping, the inner surface of the housing 8, and the like from being oxidized and corroded and deteriorated at an early stage.

酸素ガス放出口３２は、外槽部２ｏと内槽部２ｉとの間で開口するのが好ましい。これにより、酸素ガス放出口３２が洗濯物と接触することによる損傷が抑制される。 The oxygen gas discharge port 32 is preferably opened between the outer tank portion 2o and the inner tank portion 2i. As a result, damage caused by the oxygen gas discharge port 32 coming into contact with the laundry is suppressed.

また酸素ガス放出口３２には、洗濯用水Ｗ１の上面を越えて上方にのび、酸素ガスを洗濯槽２の外に排出する排気管３３が配される。 Further, the oxygen gas discharge port 32 is provided with an exhaust pipe 33 that extends upward beyond the upper surface of the washing water W1 and discharges the oxygen gas to the outside of the washing tub 2.

この排気管３３は、酸素ガス放出口３２から放出された酸素ガスが、水素水の効果を低下させるのを最小限に抑える。即ち、酸素ガスを溶解させた洗濯用水Ｗ１を、排気管３３の内側に閉じ込め、排気管３３の外側に拡散することによる洗浄効果の低下を抑制させる。なお排気管３３の排気口３３Ａは、機外、例えば筺体８の外側で開口させるのが、装置内部の腐食劣化を抑える上で好ましい。 The exhaust pipe 33 minimizes that the oxygen gas released from the oxygen gas discharge port 32 reduces the effect of hydrogen water. That is, the washing water W1 in which the oxygen gas is dissolved is confined inside the exhaust pipe 33 and diffused to the outside of the exhaust pipe 33 to suppress a decrease in the cleaning effect. It is preferable that the exhaust port 33A of the exhaust pipe 33 is opened outside the machine, for example, outside the housing 8 in order to suppress corrosion deterioration inside the device.

第４流路７にも、洗濯槽２内の洗濯用水Ｗ１が、電解槽１５の側に逆流するのを阻止する一方弁３４が配される。これにより、汚れ成分を含む洗濯用水Ｗ１による極室１６Ｂ、特に電極２２及び隔膜２３の汚損が防止される。また、一方弁３４によって、ポンプ等の送出手段を用いることなく、極室１６Ｂで発生した酸素ガスを洗濯装置１外に送出可能となる。 A valve 34 is also arranged in the fourth flow path 7 to prevent the washing water W1 in the washing tub 2 from flowing back to the side of the electrolytic cell 15. As a result, the polar chamber 16B, particularly the electrode 22 and the diaphragm 23, are prevented from being soiled by the washing water W1 containing a stain component. Further, the one-side valve 34 makes it possible to send the oxygen gas generated in the polar chamber 16B to the outside of the washing apparatus 1 without using a sending means such as a pump.

本例の電解手段３には、洗濯が終了して電解槽１５内の電気分解用水Ｗ２を排出する際に、電解槽１５内に外気を供給する吸気管３５、３６を具える。吸気管３５、３６は、本例では、第３流路６及び第４流路７を介して極室１６Ａ、１６Ｂに接続される場合が示される。しかし、第３流路６及び第４流路７を介することなく極室１６Ａ、１６Ｂに直接接続されても良い。 The electrolytic means 3 of this example includes intake pipes 35 and 36 that supply outside air into the electrolytic cell 15 when washing is completed and the electrolysis water W2 in the electrolytic cell 15 is discharged. In this example, the intake pipes 35 and 36 are connected to the polar chambers 16A and 16B via the third flow path 6 and the fourth flow path 7. However, it may be directly connected to the polar chambers 16A and 16B without passing through the third flow path 6 and the fourth flow path 7.

この吸気管３５、３６には、極室１６Ａ、１６Ｂからの水素ガス及び酸素ガスが、吸気管３５、３６を通って排気されるのを防止する一方弁３７がそれぞれ配される。 The intake pipes 35 and 36 are provided with valves 37, respectively, which prevent hydrogen gas and oxygen gas from the polar chambers 16A and 16B from being exhausted through the intake pipes 35 and 36.

本実施形態の洗濯装置１では、洗濯の開始に際し、開閉弁１４を開く。これにより、洗濯槽２内には、洗濯用水Ｗ１が給水源１２から第１流路４を介して供給される。これと同時に、電解槽１５には、電気分解用水Ｗ２が給水源１２から第２流路５を介して供給される。 In the washing apparatus 1 of the present embodiment, the on-off valve 14 is opened at the start of washing. As a result, the washing water W1 is supplied into the washing tub 2 from the water supply source 12 via the first flow path 4. At the same time, the electrolysis water W2 is supplied to the electrolytic cell 15 from the water supply source 12 via the second flow path 5.

本例では、電解槽１５に電気分解用水Ｗ２が満たされた後、電気分解用水Ｗ２は、第３流路６及び第４流路７を通って洗濯槽２に洗濯用水Ｗ１として送られる。 In this example, after the electrolytic cell 15 is filled with the electrolysis water W2, the electrolysis water W2 is sent to the washing tub 2 as the washing water W1 through the third flow path 6 and the fourth flow path 7.

そして、洗濯槽２に洗濯用水Ｗ１が満たされると、開閉弁１４が閉じられ、給水源１２からの水の供給が止められる。 Then, when the washing tub 2 is filled with the washing water W1, the on-off valve 14 is closed and the supply of water from the water supply source 12 is stopped.

本例の電解手段３では、電極２１、２２が露出しないレベルまで電解槽１５に電気分解用水Ｗ２が溜まれば、電気分解が開始される。これにより、水素水の生成時間を短縮しうる。電極２１、２２が露出しないレベルとは、例えば、電極２１、２２の全体が電気分解用水Ｗ２に浸かるレベルであり、本例では、水位センサ（図示省略）によって検出される。 In the electrolytic means 3 of this example, when the electrolysis water W2 is accumulated in the electrolytic cell 15 to a level where the electrodes 21 and 22 are not exposed, the electrolysis is started. Thereby, the generation time of hydrogen water can be shortened. The level at which the electrodes 21 and 22 are not exposed is, for example, a level at which the entire electrodes 21 and 22 are immersed in the water for electrolysis W2, and is detected by a water level sensor (not shown) in this example.

また電解槽１５から発生する水素ガスは、第３流路６を通って洗濯槽２の洗濯用水Ｗ１中に放出される。水素ガスは、洗濯用水Ｗ１に溶解し、洗濯用水Ｗ１を水素水として機能させ、洗浄効果を発揮しうる。 Further, the hydrogen gas generated from the electrolytic cell 15 is discharged into the washing water W1 of the washing tub 2 through the third flow path 6. The hydrogen gas dissolves in the washing water W1 and makes the washing water W1 function as hydrogen water, so that the washing effect can be exhibited.

また電解槽１５から発生する酸素ガスは、第４流路７及び排気管３３を通って洗濯装置１外に放出される。 Further, the oxygen gas generated from the electrolytic cell 15 is discharged to the outside of the washing apparatus 1 through the fourth flow path 7 and the exhaust pipe 33.

なお電解手段３による電気分解は洗濯中にも行われ、水素ガスを、洗濯中の洗濯用水Ｗ１中に放出させうる。これにより、洗濯中に水素濃度が低下するのを抑えることができ、洗浄効果の維持を図ることが可能になる。また洗濯物の汚れの状態に応じて水素濃度を調整することも可能となる。 The electrolysis by the electrolytic means 3 is also performed during washing, and hydrogen gas can be released into the washing water W1 during washing. As a result, it is possible to suppress a decrease in hydrogen concentration during washing, and it is possible to maintain the washing effect. It is also possible to adjust the hydrogen concentration according to the state of dirt on the laundry.

洗濯終了後、電解手段３による電気分解は停止される。その後、排水流路１０の排水弁１１及び接続流路部２４の排水弁２５が開弁することで、洗濯槽２内の洗濯用水Ｗ１及び電解槽１５内の電気分解用水Ｗ２が、機外に排出される。 After the washing is completed, the electrolysis by the electrolytic means 3 is stopped. After that, the drain valve 11 of the drainage flow path 10 and the drainage valve 25 of the connection flow path portion 24 are opened, so that the washing water W1 in the washing tub 2 and the electrolysis water W2 in the electrolytic cell 15 are removed from the machine. It is discharged.

このとき、一方弁３７を通って吸気管３５、３６から、外気が極室１６Ａ、１６Ｂに供給されるため、電解槽１５内の電気分解用水Ｗ２の排水を円滑に行うことが可能になる。なお第３流路６及び第４流路７の一方弁３１、３４は、排水の際にも、洗濯槽２内の洗濯用水Ｗ１が電解槽１５に逆流するのを防止し、電解槽１５内の汚染を防止する。 At this time, since the outside air is supplied to the polar chambers 16A and 16B from the intake pipes 35 and 36 through the one-side valve 37, the electrolysis water W2 in the electrolytic cell 15 can be smoothly drained. The one-way valves 31 and 34 of the third flow path 6 and the fourth flow path 7 prevent the washing water W1 in the washing tub 2 from flowing back into the electrolytic cell 15 even when draining, and the inside of the electrolytic cell 15. Prevent pollution.

以上、本発明の特に好ましい実施形態について詳述したが、本発明は図示の実施形態に限定されることなく、種々の態様に変形して実施しうる。すなわち、本発明は、洗濯槽２と、水を電気分解して水素ガスと酸素ガスとを発生させる電解槽１５を有する電解手段と、 給水源１２からの水を、洗濯用水Ｗ１として洗濯槽２内に送る第１流路４と、給水源１２からの水を、電気分解用水Ｗ２として電解槽１５内に送る第２流路５と、電解槽１５で発生する水素ガスを、洗濯槽２の洗濯用水Ｗ１中に放出させる水素ガス放出口３０を有する第３流路６とを含んでいればよい。 Although the particularly preferable embodiments of the present invention have been described in detail above, the present invention is not limited to the illustrated embodiments and can be modified into various embodiments. That is, in the present invention, the washing tub 2 has an electrolytic means having a washing tub 2 and an electrolytic tub 15 that electrolyzes water to generate hydrogen gas and oxygen gas, and water from the water supply source 12 is used as washing water W1. The first flow path 4 to be sent to the inside, the second flow path 5 to send the water from the water supply source 12 into the electrolytic cell 15 as the water for electrolysis W2, and the hydrogen gas generated in the electrolytic cell 15 are transferred to the washing tub 2. It may include a third flow path 6 having a hydrogen gas discharge port 30 to be discharged into the washing water W1.
