以下、本発明の好適な実施例を添付図面に基づいて詳細に説明する。
図１は本発明に適用する洗濯機を示す断面図である。図１に示すように、洗濯水の溜水のために本体ケース１０２の内部に水槽１０４が設置され、この水槽１０４の内部に回転可能に洗濯槽１０６が設置される。また、洗濯槽１０６の内部には洗濯水流を形成するように正回転及び逆回転を行うパルセーター１０８が設置され、水槽１０４の下部には洗濯槽１０６とパルセーター１０８を回転させるための駆動装置１１０が設置される。この駆動装置１１０は洗濯モータ１１２と伝動装置１１４とから構成される。洗濯モータ１１２は電源の印加を受けて回転し、伝動装置１１４はこの回転力がパルセーター１０８と洗濯槽１０６に選択的に伝達できるようにする。洗濯モータ１１２と伝動装置１１４との間には伝動を媒介するベルト１１６が連結される。また、水槽の下方に排水装置１１８が設けられる。この排水装置１１８は排水管１１８ａの途中に設置された排水バルブ１１８ｂを備える。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a sectional view showing a washing machine applied to the present invention. As shown in FIG. 1, a water tub 104 is installed inside the main body case 102 for storing the washing water, and a washing tub 106 is rotatably installed inside the water tub 104. Also, a pulsator 108 that rotates forward and backward so as to form a washing water flow is installed inside the washing tub 106, and a driving device for rotating the washing tub 106 and the pulsator 108 is provided below the water tub 104. 110 is installed. The driving device 110 includes a washing motor 112 and a transmission 114. The washing motor 112 rotates upon receiving the power supply, and the transmission 114 enables the rotational force to be selectively transmitted to the pulsator 108 and the washing tub 106. A belt 116 for transmitting power is connected between the washing motor 112 and the transmission 114. In addition, a drainage device 118 is provided below the water tank. The drainage device 118 includes a drainage valve 118b installed in the middle of the drainage pipe 118a.

洗濯機に電源を供給し、洗濯コースが設定されると、水槽１０４の内部に洗濯水が供給される。給水される洗濯水は洗剤溶解装置（図示せず）を経由して洗剤を溶解させ、洗剤と共に水槽１０４の内部に供給される。   When power is supplied to the washing machine and a washing course is set, washing water is supplied into the water tub 104. The supplied washing water dissolves the detergent via a detergent dissolving device (not shown) and is supplied to the inside of the water tub 104 together with the detergent.

使用者が殺菌洗濯コースを選択した場合には、このような給水動作と共に銀溶液供給装置１２０の入口バルブ１２４が開になることにより、貯蔵容器１２２の内部に水供給が行われる。銀溶液供給装置１２０の２つの銀板２６０、２７０に電源が印加されると、銀溶液が製造されて洗濯槽１０６の内部に供給される。すなわち、貯蔵容器１２２に供給される水は、一定量の溜水を保ったまま徐々に排出されるが、このような過程で２つの銀板２６０、２７０と水の電気分解によって銀溶液が製造される。製造された銀溶液は入口バルブ１２４を介して洗濯槽１０６へ供給される。   When the user selects the sterilization washing course, the supply of water is performed into the storage container 122 by opening the inlet valve 124 of the silver solution supply device 120 together with such a water supply operation. When power is applied to the two silver plates 260 and 270 of the silver solution supply device 120, a silver solution is produced and supplied into the washing tub 106. That is, the water supplied to the storage container 122 is gradually discharged while maintaining a certain amount of stored water. In this process, the silver solution is produced by electrolysis of the two silver plates 260 and 270 and the water. Is done. The produced silver solution is supplied to the washing tub 106 through the inlet valve 124.

図２は本発明に係る洗濯機の制御ブロック図である。
図２に示すように、本発明は銀溶液を用いた洗濯機の全般的な動作を制御するコントローラ２００を備える。前記コントローラ２００の入力端には、銀溶液を用いた殺菌洗濯コースを始めとして使用者所望の洗濯コースを選択することが可能な洗濯コース設定部２１０と、水槽１０４の内部に充填される洗濯水の水位を感知する水位感知部２２０とが連結される。前記コントローラ２００の出力端には、排水バルブ１１８ｂと給水バルブ（図示せず）を駆動するためのバルブ駆動部２３０と、洗濯モータ１１２を駆動するための洗濯モータ駆動部２４０と、水を電気分解して銀溶液を製造するように２つの銀板２６０、２７０に電源を供給するための銀溶液供給装置駆動部２５０とが連結される。 FIG. 2 is a control block diagram of the washing machine according to the present invention.
As shown in FIG. 2, the present invention includes a controller 200 for controlling the overall operation of a washing machine using a silver solution. The input terminal of the controller 200 includes a washing course setting unit 210 for selecting a desired washing course including a sterilizing washing course using a silver solution, and a washing water filled in the water tub 104. Is connected to a water level sensing unit 220 for sensing the water level. At an output end of the controller 200, a valve driving unit 230 for driving a drain valve 118b and a water supply valve (not shown), a washing motor driving unit 240 for driving the washing motor 112, and electrolysis of water And a silver solution supply device driving unit 250 for supplying power to the two silver plates 260 and 270 so as to produce a silver solution.

洗濯コース設定部２１０を用いて、使用者が銀溶液を用いた殺菌洗濯コースを設定する場合、前記コントローラ２００は、必要とする洗濯水より一定量だけ少なく初期給水（一例として必要とする洗濯水の８０％）して高濃度の洗剤が水槽に供給されるようにした後、洗濯モータ１１２を駆動して高濃度洗濯を所定の時間（一例として５分）行う。その後、２次給水（残り２０％）を補充した後、洗濯モータ１１２を第１設定時間駆動する動作と、第２設定時間洗濯モータ１１２を停止する動作とを交互に行う。すなわち、第１設定時間（一例として１分）洗濯モータ１１２を駆動して水流を発生させ、この水流発生によって洗濯水と洗濯物との摩擦を誘導して洗濯を行うようにし、第１設定時間が経つと、洗濯モータ１１２を停止させた後、第２設定時間（一例として４分）洗濯モータを停止させて水流発生を停止させることにより、洗濯水に含有された銀溶液に洗濯物が接触する時間を十分確保して洗濯物の殺菌を行う。このような洗濯物の洗濯と殺菌は、設定された殺菌洗濯時間（一例として６０分間）交互に行われる。殺菌洗濯時間が経つと、本洗濯を所定の時間行った後、洗濯行程を終了する。ここで、本洗濯は洗濯モータの正回転と逆回転を行い続けるもので、好ましくは５分に設定する。   When the user sets a sterilization washing course using a silver solution using the washing course setting unit 210, the controller 200 may supply initial water (for example, required washing water) by a fixed amount less than required washing water. After the high concentration detergent is supplied to the water tub, the washing motor 112 is driven to perform the high concentration washing for a predetermined time (for example, 5 minutes). Thereafter, after replenishing the secondary water (remaining 20%), the operation of driving the washing motor 112 for the first set time and the operation of stopping the washing motor 112 for the second set time are alternately performed. That is, the washing motor 112 is driven for the first set time (one minute as an example) to generate a water flow, and the generation of the water flow induces the friction between the washing water and the laundry to perform the washing. After the washing, the washing motor 112 is stopped, and then the washing motor is stopped for a second set time (for example, 4 minutes) to stop the generation of the water flow, so that the laundry comes into contact with the silver solution contained in the washing water. Perform sufficient time to sterilize the laundry. Such washing and sterilization of the laundry are alternately performed for a set sterilizing washing time (for example, 60 minutes). After the sterilization washing time has elapsed, the main washing is performed for a predetermined time, and then the washing process is terminated. Here, the main washing is to continuously perform the normal rotation and the reverse rotation of the washing motor, and is preferably set to 5 minutes.

次に、前記構成を有する本発明に係る洗濯機の制御方法を添付図面に基づいて説明する。
図３は使用者によって銀溶液を用いた殺菌洗濯コースを行う場合のフローチャートである。 Next, a method for controlling the washing machine according to the present invention having the above configuration will be described with reference to the accompanying drawings.
FIG. 3 is a flowchart when a user performs a sterilization washing course using a silver solution.

まず、前記コントローラ２００は、洗濯コース設定部２１０を用いて設定する洗濯コースが殺菌コースに相当すると、バルブ駆動部２３０を制御して洗濯水を給水するが、この洗濯水が洗剤溶解装置（図示せず）と銀溶液供給装置１２０を経由して洗剤及び銀溶液と共に水槽１０４の内部に洗濯水を給水する（３００）。次に、前記コントローラ２００は、水位感知部２２０で感知される洗濯水位が必要とする洗濯水位より一定量だけ低い水位（実施例では洗濯水位の８０％）に到達したか否かによって初期給水が完了したか否かを判断する（３０２）。ここで、初期給水時に洗濯水を少なく供給する理由は高濃度の洗剤で洗濯物を洗濯するためである。   First, when the washing course set by using the washing course setting unit 210 corresponds to the sterilization course, the controller 200 controls the valve driving unit 230 to supply the washing water. The washing water is supplied to the inside of the water tub 104 together with the detergent and the silver solution via the silver solution supply device 120 (not shown) (300). Next, the controller 200 determines whether or not the initial water supply is based on whether the washing water level sensed by the water level sensing unit 220 has reached a water level lower than the required washing water level by a certain amount (in the embodiment, 80% of the washing water level). It is determined whether or not the processing has been completed (302). Here, the reason for supplying a small amount of washing water at the time of initial water supply is to wash laundry with a high concentration of detergent.

動作（３０２）の判断結果、初期給水が完了しなければ、前記動作（３００）に戻り、初期給水が完了すれば、水槽１０４に高濃度の洗剤、銀溶液及び洗濯水が供給された状態で、前記コントローラ２００は洗濯モータ駆動部２４０を制御して洗濯モータ１１２を駆動して高濃度洗濯を行う（３０４）。   If it is determined in operation (302) that the initial water supply is not completed, the process returns to operation (300). If the initial water supply is completed, the water tank 104 is supplied with a high concentration of detergent, silver solution, and washing water. The controller 200 controls the washing motor driving unit 240 to drive the washing motor 112 to perform high-concentration washing (304).

高濃度洗濯を行う途中で、前記コントローラ２００は、設定された高濃度洗濯時間（一例として５分）が経過したか否かを判断し（３０６）、その判断結果、高濃度洗濯時間が経過していない場合には動作（３０４）に戻り、高濃度洗濯時間が経過した場合にはバルブ駆動部２３０を制御して２次給水を行う。ここで、２次給水は必要とする洗濯水位から初期給水時に供給した洗濯水の水位を差し引いた残余洗濯水（一例として洗濯水位の２０％）を供給する（３０８）。   In the course of performing the high-concentration washing, the controller 200 determines whether or not the set high-concentration washing time (for example, 5 minutes) has elapsed (306). If not, the process returns to the operation (304), and if the high-concentration washing time has elapsed, the valve driving unit 230 is controlled to perform secondary water supply. Here, as the secondary water supply, the remaining wash water (20% of the wash water level as an example) is supplied by subtracting the water level of the wash water supplied at the time of initial water supply from the required wash water level (308).

前記コントローラ２００は、２次給水が完了したか否かを判断し（３１０）、その判断結果、２次給水が完了しなければ動作（３０８）に戻って２次給水を行い続け、その判断結果、２次給水が完了すれば動作（３１２）に移行する。   The controller 200 determines whether or not the secondary water supply is completed (310). If the result of the determination is that the secondary water supply is not completed, the controller 200 returns to the operation (308) and continues to perform the secondary water supply. When the secondary water supply is completed, the operation proceeds to operation (312).

後述の動作（３１２）ないし動作（３２０）は水流発生を制御して前記洗濯物に対する洗濯と殺菌を交互に行うもので、これにより洗濯モータの長時間の駆動による洗濯物の損傷を防止し且つ銀溶液と洗濯物との十分な接触によって殺菌効果を増大させることができる。これを説明すると、次の通りである。   Operations 312 to 320 described below control the generation of water flow to alternately wash and sterilize the laundry, thereby preventing damage to the laundry due to long-time driving of the washing motor, and Good contact between the silver solution and the laundry can increase the bactericidal effect. This will be described as follows.

２次給水が完了した場合、前記コントローラ２００は、内蔵されたカウンタを用いて洗濯時間をカウントすると共に、洗濯モータ駆動部２４０を制御して洗濯モータ１１２を駆動し、これにより水流が発生し、発生した水流によって洗濯水と洗濯物との摩擦により洗濯が行われる（３１２）。次に、前記コントローラ２００は、第１設定時間（一例として１分）が経過したか否かを判断し（３１４）、その判断結果、第１設定時間が経過していない場合には、水流を発生させ続けるために洗濯モータ１１２を駆動し、その判断結果、第１設定時間が経過した場合には、洗濯モータ駆動部２４０を制御して洗濯モータ１１２を停止する（３１６）。次に、前記コントローラ２００は、第２設定時間（一例として４分）が経過したか否かを判断し（３１８）、その判断結果、第２設定時間が経過していない場合には、引き続き水流の発生を停止させるために洗濯モータ１１２を停止する。その判断結果、第２設定時間が経過した場合には、カウントされた洗濯時間が設定の殺菌洗濯時間（一例として６０分）を経過したか否かを判断し（３２０）、その判断結果、カウントした洗濯時間が設定の殺菌洗濯時間を経過していない場合には、洗濯モータ１１２の駆動と停止を交互に行う動作を持続するために動作（３１２）に戻る。   When the secondary water supply is completed, the controller 200 counts the washing time using a built-in counter, controls the washing motor driving unit 240 to drive the washing motor 112, thereby generating a water flow, Washing is performed by friction between the washing water and the laundry by the generated water flow (312). Next, the controller 200 determines whether or not a first set time (for example, one minute) has elapsed (314). The washing motor 112 is driven to continue the generation, and as a result of the determination, if the first set time has elapsed, the washing motor driving unit 240 is controlled to stop the washing motor 112 (316). Next, the controller 200 determines whether or not a second set time (for example, 4 minutes) has elapsed (318). If the result of the determination is that the second set time has not elapsed, the controller 200 continues the water flow. The washing motor 112 is stopped to stop the occurrence of the washing. If the result of the determination is that the second set time has elapsed, it is determined whether or not the counted washing time has passed the set sterilization washing time (for example, 60 minutes) (320). If the set washing time has not passed the set sterilization washing time, the process returns to the operation (312) to continue the operation of alternately driving and stopping the washing motor 112.
