詳しく図示はしないが、前記ポンプ２８は、２組の吸入口及び吐出口２８ａ（図６参照）を有しており、モータを駆動源として構成されている。このポンプ２８は、モータの回転方向（通電方向）の切替により、液体を吸い込む吸入口及び吐出する吐出口２８ａを切替える構成とされている。このとき、一方の吸入口が洗剤タンク３０側に接続され、モータの一方向の回転により洗剤を汲み上げて一方の吐出口２８ａから吐出するように構成されている。他方の吸入口が柔軟剤タンク３１側に接続され、モータの他方向の回転により柔軟剤を汲み上げ、他方の吐出口２８ａから吐出するように構成されている。このポンプ２８の２個の吐出口２８ａは、図５～図７にも示すように、メイン給水経路１４の洗剤供給部２５の上方に左右に配置されている。また、ポンプ２８の駆動時間によって、洗剤や柔軟剤の吐出量、即ち洗剤供給部２５への供給量が制御される。 Although not shown in detail, the pump 28 has two sets of suction ports and discharge ports 28a (see FIG. 6), and is configured with a motor as a drive source. The pump 28 is configured to switch between a suction port for sucking liquid and a discharge port 28a for discharging liquid by switching the rotation direction (energization direction) of the motor. At this time, one suction port is connected to the detergent tank 30 side, and the detergent is pumped up by one-way rotation of the motor and discharged from the one discharge port 28a. The other suction port is connected to the softener tank 31 side, and the softener is pumped up by rotation in the other direction of the motor and discharged from the other discharge port 28a. As shown in FIGS. 5 to 7, the two discharge ports 28a of the pump 28 are arranged on the left and right above the detergent supply unit 25 of the main water supply path 14. Further, the discharge amount of the detergent or the softener, that is, the supply amount to the detergent supply unit 25 is controlled by the driving time of the pump 28.

これにて、洗剤自動投入装置１１は、ポンプ２８の駆動により、洗剤タンク３０内に収容されていた洗剤を、所要量だけ洗剤供給部２５に供給することができ、また、柔軟剤タンク３１内に収容されていた柔軟剤を、所要量だけ洗剤供給部２５に供給することができる。ポンプ２８の吐出口２８ａがメイン給水経路１４に接続されていることで、洗剤の供給経路が全体的に短くなり、また、供給経路内での洗剤の固着も防止できる。このとき、洗剤供給部２５に、洗剤或いは柔軟剤が供給されている状態で、前記メイン給水弁１６がオンされてメイン給水経路１４に給水がなされると、その水は洗剤供給部２５において洗剤或いは柔軟剤を溶かしながら流れる。給水により吐出口２８ａを洗い流すことができるので、洗剤が吐出口２８ａ部分で固着することも防止できる。そして、洗剤或いは柔軟剤は給水と共に注水口２３から手動用洗剤収容部１３ａに供給され、更に注水ケース１２から給水ダクト１５を通って水槽６内に供給される。 With this, the detergent automatic charging device 11 can supply the detergent contained in the detergent tank 30 to the detergent supply unit 25 in a required amount by driving the pump 28, and also in the softener tank 31. The softener contained in the detergent can be supplied to the detergent supply unit 25 in a required amount. Since the discharge port 28a of the pump 28 is connected to the main water supply path 14, the detergent supply path is shortened as a whole, and the detergent can be prevented from sticking in the supply path. At this time, when the main water supply valve 16 is turned on and water is supplied to the main water supply path 14 while the detergent or the softener is being supplied to the detergent supply unit 25, the water is detergent in the detergent supply unit 25. Alternatively, it flows while melting the softener. Since the discharge port 28a can be washed away by the water supply, it is possible to prevent the detergent from sticking to the discharge port 28a portion. Then, the detergent or the softener is supplied to the manual detergent accommodating portion 13a from the water injection port 23 together with the water supply, and further supplied from the water injection case 12 to the water tank 6 through the water supply duct 15.

図示はしないが、本体１内には、例えばマイクロコンピュータを主体に構成され、洗濯機全体の制御を行う制御装置が設けられている。制御装置は、操作パネル５においてユーザにより設定される運転コースに応じて、各センサからの入力信号や予め記憶された制御プログラムに基づいて、前記給水弁ユニット１０の各給水弁１６、１７、１８、洗剤自動投入装置１１のポンプ２８、ドラムモータ、排水弁、乾燥機構等を制御する。これにて、洗い行程、すすぎ行程、脱水行程からなる洗濯運転や、乾燥運転を自動で実行する。これら洗濯運転や乾燥運転の各行程の詳細については、周知であるのでここでは説明を省略する。 Although not shown, a control device that is mainly composed of a microcomputer, for example, and controls the entire washing machine is provided in the main body 1. The control device has the water supply valves 16, 17, and 18 of the water supply valve unit 10 based on the input signals from the sensors and the control program stored in advance according to the operation course set by the user on the operation panel 5. , The pump 28 of the automatic detergent charging device 11, the drum motor, the drain valve, the drying mechanism, and the like are controlled. With this, the washing operation consisting of the washing process, the rinsing process, and the dehydrating process and the drying operation are automatically executed. Since the details of each process of the washing operation and the drying operation are well known, the description thereof will be omitted here.

本実施形態では、ユーザは、洗濯運転を実行させるにあたって、洗剤自動投入装置１１により自動で洗剤及び柔軟剤を投入するか、或いは、手動用収容ケース１３を用いて手動で１回分の洗剤や柔軟剤を投入するかを、操作パネル５上で選択操作できるようになっている。ユーザは、手動での投入を選択した場合には、洗濯運転開始時に、予め、蓋２２を開放して手動用収容ケース１３の手動用洗剤収容部１３ａに必要量の洗剤（粉末洗剤）を収容しておく。また柔軟剤を用いる場合には、上記と併せて、手動用柔軟剤収容部１３ｂに所要量の柔軟剤を投入しておく。 In the present embodiment, when the user executes the washing operation, the detergent and the softener are automatically added by the detergent automatic addition device 11, or the detergent and the softener for one time are manually added by using the manual storage case 13. It is possible to select and operate on the operation panel 5 whether to add the agent. When the user selects manual charging, the lid 22 is opened in advance at the start of the washing operation, and the required amount of detergent (powder detergent) is stored in the manual detergent storage unit 13a of the manual storage case 13. I'll do it. When a softener is used, a required amount of the softener is charged into the manual softener accommodating portion 13b in addition to the above.

制御装置は、洗剤及び柔軟剤の自動投入が選択されている場合には、洗い行程の給水開始前に、洗剤自動投入装置１１により所要量の洗剤を洗剤供給部２５に供給し、その後、メイン給水弁１６をオンして給水を実行する。また、最終のためすすぎ行程の前に、洗剤自動投入装置１１により所要量の柔軟剤を洗剤供給部２５に供給しておき、その後、メイン給水弁１６を開放して給水を行う。これに対し、洗剤及び柔軟剤の手動での投入が選択されている場合には、洗剤自動投入装置１１を動作させることなく、メイン給水弁１６により洗い行程の給水を実行する。そして、最終のためすすぎ行程の給水時には、メイン給水弁１６でなく柔軟剤用給水弁１７を開放させて給水を行う。 When automatic addition of detergent and softener is selected, the control device supplies the required amount of detergent to the detergent supply unit 25 by the automatic detergent addition device 11 before the start of water supply in the washing process, and then the main The water supply valve 16 is turned on to supply water. Further, before the final rinsing process, the required amount of the softener is supplied to the detergent supply unit 25 by the detergent automatic charging device 11, and then the main water supply valve 16 is opened to supply water. On the other hand, when the manual addition of the detergent and the softener is selected, the water supply in the washing process is executed by the main water supply valve 16 without operating the detergent automatic addition device 11. Then, at the time of water supply in the final rinsing process, water is supplied by opening the water supply valve 17 for the softener instead of the main water supply valve 16.

次に、上記構成の洗濯機の作用・効果について述べる。上記洗剤自動投入装置１１を使用する準備として、ユーザは、洗剤タンク３０内に洗剤を収容させておくと共に、柔軟剤タンク３１に柔軟剤を収容させておく。タンク３０、３１に対する洗剤、柔軟剤の収容、補充の作業は、次のように行うことができる。即ち、ユーザは、本体１の前面の前扉２９の手掛け部２９ａに手指を掛けて、収納位置にあるタンクケース２７を手前に引き出す。タンクケース２７の引出し位置で、洗剤タンク３０又は柔軟剤タンク３１を上方に取出し、タンク３０、３１に対する洗剤、柔軟剤の補充作業を行う。補充作業後、タンク３０、３１をタンクケース２７に戻し、タンクケース２７を押込んで収納位置に戻す。尚、各タンク３０、３１の上面に蓋を設けて、タンクケース２７を引出してその蓋を開けて（タンク３０、３１を取出さずに）、洗剤、柔軟剤の補充作業を行うように構成することもできる。 Next, the operation and effect of the washing machine having the above configuration will be described. In preparation for using the detergent automatic charging device 11, the user stores the detergent in the detergent tank 30 and stores the softener in the softener tank 31. The operations of storing and replenishing the detergent and the softener in the tanks 30 and 31 can be performed as follows. That is, the user puts his / her finger on the handle portion 29a of the front door 29 on the front surface of the main body 1 and pulls out the tank case 27 in the storage position toward the front. At the drawer position of the tank case 27, the detergent tank 30 or the softener tank 31 is taken out upward, and the detergent and the softener are replenished to the tanks 30 and 31. After the replenishment work, the tanks 30 and 31 are returned to the tank case 27, and the tank case 27 is pushed in to return to the storage position. A lid is provided on the upper surface of each of the tanks 30 and 31, and the tank case 27 is pulled out and the lid is opened (without removing the tanks 30 and 31) to replenish the detergent and the softener. You can also do it.

洗濯機において洗濯運転を実行させるにあたっては、ユーザは、電源スイッチ４を操作して電源をオンし、ドラム内に衣類を収容する。これと共に、操作パネル５により運転コースを選択する。このとき、洗剤及び柔軟剤の手動投入を選択した場合には、ユーザは、本体１上面の蓋２２を開け、手動用収容ケース１３の手動用洗剤収容部１３ａに必要量の洗剤を収容させ、手動用柔軟剤収容部１３ｂに所要量の柔軟剤を投入し、洗濯運転をスタートさせる。洗剤及び柔軟剤の自動投入を選択した場合には、そのまま洗濯運転をスタートさせることができる。 In executing the washing operation in the washing machine, the user operates the power switch 4 to turn on the power and store the clothes in the drum. At the same time, the driving course is selected by the operation panel 5. At this time, when the manual addition of the detergent and the softener is selected, the user opens the lid 22 on the upper surface of the main body 1 and stores the required amount of detergent in the manual detergent accommodating portion 13a of the manual accommodating case 13. A required amount of softener is charged into the manual softener accommodating portion 13b, and the washing operation is started. If the automatic addition of detergent and softener is selected, the washing operation can be started as it is.

制御装置は、洗濯運転がスタートされると、洗濯機の各機構を制御し、周知の洗い、すすぎ、脱水の各行程からなる洗濯運転を自動で実行する。このとき、洗い行程では、まず、水槽６内への所定水位までの給水が行われるのであるが、洗剤の自動投入が選択されている場合には、給水開始前に、洗剤自動投入装置１１のポンプ２８を制御することにより、洗剤供給部２５に対し所要量の洗剤が供給される。給水動作においては、メイン給水弁１６が開放される。 When the washing operation is started, the control device controls each mechanism of the washing machine and automatically executes the washing operation including the well-known washing, rinsing, and dehydrating processes. At this time, in the washing process, water is first supplied to the water tank 6 up to a predetermined water level, but if automatic detergent charging is selected, the detergent automatic charging device 11 is used before the start of water supply. By controlling the pump 28, a required amount of detergent is supplied to the detergent supply unit 25. In the water supply operation, the main water supply valve 16 is opened.

メイン給水弁１６が開放されると、図５～図７に太矢印で示すように、給水源（水道）からの水がメイン給水経路１４を流れ、洗剤供給部２５部分を通った後、上昇して注水口２３から手動用収容ケース１３の手動用洗剤収容部１３ａ内に注がれる。洗剤供給部２５に洗剤が自動で供給されていた場合には、その洗剤を溶かしながら流れ、手動用洗剤収容部１３ａから注水ケース１２及び給水ダクト１５を順に通って、水槽６内に洗剤を含んだ洗濯水が給水され、洗い行程が実行される。 When the main water supply valve 16 is opened, as shown by the thick arrows in FIGS. 5 to 7, water from the water supply source (water supply) flows through the main water supply path 14, passes through the detergent supply section 25, and then rises. Then, it is poured from the water injection port 23 into the manual detergent accommodating portion 13a of the manual accommodating case 13. When the detergent is automatically supplied to the detergent supply unit 25, the detergent flows while being melted, passes through the water injection case 12 and the water supply duct 15 in order from the manual detergent storage unit 13a, and contains the detergent in the water tank 6. However, the washing water is supplied and the washing process is executed.

一方、洗剤の手動投入が選択されていた場合には、洗剤供給部２５に洗剤が存在しないので、メイン給水経路１４を流れる水は、洗剤供給部２５部分をそのまま通過し、注水口２３から手動用洗剤収容部１３ａ内に注がれる。そして、手動用洗剤収容部１３ａ内に予め収容されていた洗剤を溶かしながら注水ケース１２に流れ、給水ダクト１５を通って水槽６内に洗剤を含んだ洗濯水が給水され、洗い行程が実行される。 On the other hand, when the manual injection of the detergent is selected, since the detergent does not exist in the detergent supply unit 25, the water flowing through the main water supply path 14 passes through the detergent supply unit 25 as it is and is manually injected from the water injection port 23. It is poured into the detergent accommodating portion 13a. Then, the detergent stored in the manual detergent accommodating portion 13a is melted and flows into the water injection case 12, the washing water containing the detergent is supplied into the water tank 6 through the water supply duct 15, and the washing process is executed. To.

この後、行程が進み、最後のためすすぎ行程の給水の前になると、洗剤の自動投入が選択されている場合には、洗剤自動投入装置１１のポンプ２８が駆動され、今度は洗剤供給部２５に対し所要量の柔軟剤が供給される。この後、メイン給水弁１６が開放され、メイン給水経路１４を流れる水が、洗剤供給部２５部分で柔軟剤を溶かしながら流れ、上昇して注水口２３から手動用収容ケース１３の手動用洗剤収容部１３ａ内に注がれる。柔軟仕上げ剤を含んだ洗濯水が、注水ケース１２及び給水ダクト１５を順に通って水槽６内に給水され、最後のためすすぎ行程が実行される。 After that, when the process progresses and before the water supply in the rinsing process for the last time, the pump 28 of the detergent automatic charging device 11 is driven when the automatic detergent charging is selected, and this time, the detergent supply unit 25 is driven. The required amount of softener is supplied to the product. After that, the main water supply valve 16 is opened, and the water flowing through the main water supply path 14 flows while melting the softener in the detergent supply section 25, rises, and stores the manual detergent in the manual storage case 13 from the water injection port 23. It is poured into the portion 13a. The washing water containing the fabric softener is supplied into the water tank 6 through the water injection case 12 and the water supply duct 15 in order, and the final rinsing process is executed.

これに対し、手動投入が選択されている場合には、最後のためすすぎ行程の給水が、メイン給水弁１６ではなく、柔軟剤用給水弁１７を開放させることにより行われる。柔軟剤用給水弁１７の開放により、図５に白抜き矢印で示すように、水が柔軟剤用給水経路２０を流れ柔軟剤用注水口２４から手動用柔軟剤収容部１３ｂ内に注がれる。そして、手動用柔軟剤収容部１３ｂ内に予め収容されていた柔軟剤を溶かしながら注水ケース１２に流れ、柔軟仕上げ剤を含んだ洗濯水が、給水ダクト１５を通って水槽６内に給水され、最後のためすすぎ行程が実行される。 On the other hand, when manual charging is selected, the water supply in the final rinsing process is performed by opening the water supply valve 17 for the softener instead of the main water supply valve 16. By opening the water supply valve 17 for the softener, water flows through the water supply path 20 for the softener and is poured into the manual softener accommodating portion 13b from the water injection port 24 for the softener, as shown by the white arrow in FIG. .. Then, while melting the softener previously stored in the manual softener accommodating portion 13b, the fabric softener flows into the water injection case 12, and the washing water containing the softener is supplied into the water tank 6 through the water supply duct 15. The rinse process is performed for the last time.

ここで、本実施形態では、給水機構７のうち、給水弁ユニット１０（メイン給水弁１６）は本体１の後部に設けられ、本体１の前部に洗剤自動投入装置１１が設けられ、それらの間に、手動用収容ケース１３を設ける構成としている。洗剤自動投入装置１１は、本体１の上部の手前側に設けられているので、後部に配置される場合と比べて、ユーザは、洗剤タンク３０、柔軟剤タンク３１が取出しやすく、それらタンク３０、３１に対する洗剤、柔軟剤の補充作業を容易に行うことができる。特に、タンク３０、３１を取出して洗剤、柔軟剤の補充をした場合、タンク３０、３１が重くなる事情があるが、タンク３０、３１が手前側にあるため、装着が比較的容易となる。 Here, in the present embodiment, among the water supply mechanisms 7, the water supply valve unit 10 (main water supply valve 16) is provided at the rear portion of the main body 1, and the detergent automatic charging device 11 is provided at the front portion of the main body 1. A storage case 13 for manual operation is provided between them. Since the detergent automatic charging device 11 is provided on the front side of the upper part of the main body 1, the user can easily take out the detergent tank 30 and the softener tank 31 as compared with the case where the detergent tank 30 and the softener tank 31 are arranged at the rear part. The detergent and softener replenishment work for 31 can be easily performed. In particular, when the tanks 30 and 31 are taken out and replenished with detergent and a softener, the tanks 30 and 31 may become heavy, but since the tanks 30 and 31 are on the front side, the mounting becomes relatively easy.

そして、給水弁ユニット１０から手動用収容ケース１３の手動用洗剤収容部１３ａまでは近いので、その間の給水経路の長さも比較的短く済み、これと共に、給水弁ユニット１０のメイン給水弁１６から洗剤自動投入装置１１の洗剤供給部２５までの位置も、比較的近く、つまり手動用収容ケース１３の少し前にすることができるので、その間の給水経路の長さも短く済む。従って、メイン給水経路１４の長さを全体として比較的短く済ませることができる。また、柔軟剤用給水経路２０の長さも短く済ませることができる。 Since the water supply valve unit 10 is close to the manual detergent storage portion 13a of the manual storage case 13, the length of the water supply path between them is relatively short, and at the same time, the detergent is supplied from the main water supply valve 16 of the water supply valve unit 10. Since the position of the automatic charging device 11 to the detergent supply unit 25 can be relatively close, that is, slightly in front of the manual storage case 13, the length of the water supply path between them can be shortened. Therefore, the length of the main water supply path 14 can be made relatively short as a whole. Further, the length of the water supply path 20 for the softener can be shortened.

この結果、本実施形態によれば、洗剤自動投入装置１１を備えるものにあって、タンク３０、３１内への洗剤、柔軟剤の補充のための作業性を良好とすることができ、しかも、給水経路１４、２０を全体として比較的短く済ませることができるという優れた効果を得ることができる。このとき、本実施形態では、洗剤自動投入装置１１の後端側に洗剤供給部２５を配置することになり、これにより、洗剤自動投入装置１１の側部（正面視で周囲）に給水経路を設けなくても良くなる。そのため、洗剤自動投入装置１１をコンパクトに配置でき、言い換えると洗剤タンク３０、柔軟剤タンク３１の容量を大型化できることになる。 As a result, according to the present embodiment, in the one provided with the detergent automatic charging device 11, the workability for replenishing the detergent and the softener into the tanks 30 and 31 can be improved, and moreover, the workability can be improved. It is possible to obtain an excellent effect that the water supply routes 14 and 20 can be made relatively short as a whole. At this time, in the present embodiment, the detergent supply unit 25 is arranged on the rear end side of the detergent automatic charging device 11, whereby the water supply path is provided on the side portion (periphery in front view) of the detergent automatic charging device 11. It does not have to be provided. Therefore, the detergent automatic charging device 11 can be arranged compactly, in other words, the capacities of the detergent tank 30 and the softener tank 31 can be increased.

特に本実施形態では、洗剤自動投入装置１１の洗剤供給部２５は、メイン給水経路１４の上流側に設けられ、手動用洗剤収容部１３ａは、それより下流側に設けられている。これにより、メイン給水経路１４を、洗剤自動投入装置１１及び手動用洗剤収容部１３ａに対して共用化することができて、メイン給水弁１６も共用化して、給水経路の切り替えのための機構を不要とすることができる。従って、大幅な構成の簡単化や、制御の簡単化を図ることができ、コストダウンを図ることができる。 In particular, in the present embodiment, the detergent supply unit 25 of the automatic detergent charging device 11 is provided on the upstream side of the main water supply path 14, and the manual detergent storage unit 13a is provided on the downstream side of the main water supply path 14. As a result, the main water supply path 14 can be shared with the detergent automatic charging device 11 and the manual detergent accommodating portion 13a, and the main water supply valve 16 can also be shared to provide a mechanism for switching the water supply path. It can be unnecessary. Therefore, it is possible to greatly simplify the configuration and control, and it is possible to reduce the cost.

また、手動用洗剤収容部１３ａを用いる場合でも、給水が洗剤供給部２５を通過するようになり、これと共に、洗剤自動投入装置１１を用いる場合でも、給水が手動用洗剤収容部１３ａを通過するようになる。これにより、毎回の給水時に、洗剤供給部２５及び手動用洗剤収容部１３ａの洗浄を行うことができる。 Further, even when the manual detergent storage unit 13a is used, the water supply passes through the detergent supply unit 25, and at the same time, even when the detergent automatic charging device 11 is used, the water supply passes through the manual detergent storage unit 13a. It will be like. As a result, the detergent supply unit 25 and the manual detergent storage unit 13a can be cleaned at each water supply.

本実施形態では、洗剤自動投入装置１１の洗剤供給部２５は、メイン給水弁１６の高さよりも低い位置にあり、メイン給水経路１４は、洗剤供給部２５の下流で上昇して手動用洗剤収容部１３ａの上方の注水口２３からから注水するように構成されている。これにより、メイン給水経路１４のうち洗剤供給部２５部分は、メイン給水弁１６の出口部の位置よりも低い位置にあるので、メイン給水弁１６に対する水の逆流を防止することができる。また、メイン給水経路１４は、洗剤供給部２５の下流で上昇して手動用洗剤収容部１３ａの上方から注水するように構成されているので、手動用洗剤収容部１３ａにおいて上方から勢い良く水を注ぐことができ、手動用洗剤収容部１３ａ内の粉末洗剤を効果的に流す、つまり流し残りなく流出させることが可能となる。 In the present embodiment, the detergent supply unit 25 of the automatic detergent charging device 11 is located at a position lower than the height of the main water supply valve 16, and the main water supply path 14 rises downstream of the detergent supply unit 25 to accommodate manual detergent. It is configured to inject water from the water injection port 23 above the portion 13a. As a result, since the detergent supply section 25 portion of the main water supply path 14 is located at a position lower than the position of the outlet portion of the main water supply valve 16, it is possible to prevent backflow of water to the main water supply valve 16. Further, since the main water supply path 14 is configured to rise downstream of the detergent supply unit 25 and inject water from above the manual detergent storage unit 13a, the manual detergent storage unit 13a vigorously injects water from above. It can be poured, and the powder detergent in the manual detergent accommodating portion 13a can be effectively flushed, that is, it can be drained without leaving any residue.

更に本実施形態では、メイン給水経路１４のうち最低部分には、メイン給水弁１６の停止時に水を抜くための水抜き経路２６を設けるようにした。メイン給水弁１６の停止時には、メイン給水経路１４のうちメイン給水弁１６の出口部から洗剤供給部２５部分にかけて水が溜まることが考えられるが、水抜き経路２６を設けたことにより、その部分に水が溜まったままとなることを未然に防止することができる。水が溜まったままとなることを防止することで、給水経路内での水の凍結を防止することができる。 Further, in the present embodiment, the lowest portion of the main water supply path 14 is provided with a drainage path 26 for draining water when the main water supply valve 16 is stopped. When the main water supply valve 16 is stopped, it is conceivable that water collects from the outlet portion of the main water supply valve 16 to the detergent supply portion 25 of the main water supply path 14, but by providing the drainage path 26, it is possible that water collects in that portion. It is possible to prevent water from remaining in the pool. By preventing the water from remaining accumulated, it is possible to prevent the water from freezing in the water supply path.

（２）第２の実施形態、その他の実施形態
次に、図８～図１４を参照して、第２の実施形態について述べる。尚、上記第１の実施形態と同一部分には、同一符号を付して新たな図示や詳しい説明を省略し、第１の実施形態と異なる点を中心に述べる。この第２の実施形態が、上記第１の実施形態と異なるところは、給水機構４１の構成にあり、給水弁を設ける数や、給水経路の具体的構成が上記第１の実施形態と異なっている。 (2) Second Embodiment, Other Embodiments Next, the second embodiment will be described with reference to FIGS. 8 to 14.

There is.

即ち、給水機構４１は、本体１内の左側上部の後部に設けられた給水弁ユニット４２、本体１内の左側上部の前部に設けられた洗剤自動投入装置１１、それらの中間に設けられた注水ケース１２及び手動用収容ケース４３、給水弁ユニット４２から注水ケース１２につながる後述する３つの給水経路４４、４５、４６、注水ケース１２から水槽６内に給水を行うための給水ダクト１５等を備えている。 That is, the water supply mechanism 41 is provided in the middle of the water supply valve unit 42 provided in the rear part of the upper left side in the main body 1, the automatic detergent charging device 11 provided in the front part of the upper left side in the main body 1. A water injection case 12, a manual storage case 43, three water supply paths 44, 45, 46 described later connected to the water injection case 12 from the water supply valve unit 42, a water supply duct 15 for supplying water from the water injection case 12 into the water tank 6, and the like. I have.

図１０等に示すように、前記給水弁ユニット４２は、フレーム４２ａに、電磁的に開閉動作する自動用給水弁４７、手動用給水弁４８、手動柔軟剤用給水弁４９、ダクト洗浄用給水弁１８を備えている。詳しく図示はしないが、給水源としての水道が接続される接続口は、４つに分岐し、各給水弁４７、４８、４９，１８の入口部に夫々接続されている。図８、図９に示すように、自動用給水弁４７の出口部が、第１給水経路４４の入口部に接続され、手動用給水弁４８の出口部が、第２給水経路４５の入口部に接続されている。手動柔軟剤用給水弁４９の出口部が、柔軟剤用給水経路４６の入口部に接続されている。 As shown in FIG. 10 and the like, the water supply valve unit 42 has an automatic water supply valve 47, a manual water supply valve 48, a manual softener water supply valve 49, and a duct cleaning water supply valve that open and close electromagnetically on the frame 42a. Equipped with 18.
