[作用]
本発明は上述のように構成されるものであり、以下、その作用について図4に従って説明する。ステップS1において短時間運転の洗い若しくはすすぎを開始するとステップS2で給水を行い、ステップS3において給水量センサ38で水道水の給水量能力を判断する。即ち、水道水の給水量を標準値と比較する。
[Action]
The present invention is configured as described above, and the operation thereof will be described with reference to FIG. When washing or rinsing for a short time operation is started in step S1, water is supplied in step S2, and the water supply capacity of the tap water is determined by the water supply sensor 38 in step S3. That is, the amount of tap water supplied is compared with a standard value.

この比較の結果、略等しい(普通)と判断されると、ステップS4に進んで駆動回路32の制御に従って駆動モータ5を介してパルセータ4の回転数を徐々に高め、標準の徐々に強くなる水流による「標準なじませ運転」を行う。この「標準なじませ運転」を所定時間続行した後、「標準洗い(すすぎ)運転」を行う(ステップS9)。又、ステップS3で流量が少ない(少量)と判定されたときは、ステップS7で給水時間設定手段の動作に従って給水設定時間の延長を行い、この状態で上記駆動回路32の制御に基づいて駆動モータ5を介してパルセータ4の回転数を制御し、「標準なじませ運転」に比べてゆっくりとした変化で水流が強くなる「給水延長設定なじませ運転」(ステップS8)を行う。   If it is determined as a result of this comparison that they are substantially equal (ordinary), the process proceeds to step S4 where the rotational speed of the pulsator 4 is gradually increased via the drive motor 5 according to the control of the drive circuit 32, and the standard gradually increasing water flow Perform “standard acclimation operation”. After this “standard blending operation” is continued for a predetermined time, a “standard washing (rinsing) operation” is performed (step S9). If it is determined in step S3 that the flow rate is small (small amount), the water supply set time is extended according to the operation of the water supply time setting means in step S7, and the drive motor is controlled based on the control of the drive circuit 32 in this state. The number of revolutions of the pulsator 4 is controlled via 5 and a “water supply extension setting acclimation operation” (step S8) in which the water flow becomes stronger with a slower change than the “standard acclimation operation”.

そして、この運転を所定時間実行した後、「給水量少量洗い(すすぎ)運転」を行う(ステップS11)。又、上記ステップS3で流量が多量と判断されると、ステップS5において上記給水時間設定手段の動作に従って給水設定時間短縮を行い、この状態で上記駆動回路32の制御に基づいて駆動モータ5を介してパルセータ4の回転数を制御し、「標準なじませ運転」に比べて急な変化で水流が強くなる「給水短縮設定なじませ運転」(ステップS6)を行う。そして、この運転を所定時間実行した後、「標準洗い(すすぎ)運転」を実行する(ステップS10)。   Then, after this operation is executed for a predetermined time, a “water supply amount small amount washing (rinsing) operation” is performed (step S11). If it is determined in step S3 that the flow rate is large, in step S5, the water supply setting time is shortened according to the operation of the water supply time setting means, and in this state, the drive motor 5 is controlled based on the control of the drive circuit 32. Then, the number of revolutions of the pulsator 4 is controlled, and the “water supply shortening set-in operation” (step S6) in which the water flow becomes stronger due to a sudden change compared to the “standard in-operation operation” (step S6). And after performing this driving | running for the predetermined time, "standard washing (rinsing) driving | running | working" is performed (step S10).

図5は水量が非常に少ないことから洗濯を早く終わらせたい場合の動作フローを示している。この動作フローでは、先ず、洗濯物を投入した上で電源スイッチ18及び10分(短時間)コース選択スイッチ34を順次ONする(ステップS1、S2)と、このスイッチ34のONを示す信号が入力回路17を通じてマイコン16に入力され、これに伴ってCPU16cの指令により表示回路26に最大布量表示信号を出力する。すると、該表示回路26は、図3の運転表示部、操作表示部の最大布量表示部37に最大布量(本例では2.5Kg)を表示させる(ステップS3)。   FIG. 5 shows an operation flow in a case where the amount of water is very small and it is desired to finish washing quickly. In this operation flow, first, after the laundry is put in, the power switch 18 and the course selection switch 34 are sequentially turned on for 10 minutes (short time) (steps S1 and S2), and a signal indicating that the switch 34 is turned on is input. A maximum cloth amount display signal is output to the display circuit 26 in response to an instruction from the CPU 16c. Then, the display circuit 26 displays the maximum cloth amount (2.5 Kg in this example) on the maximum cloth amount display unit 37 of the operation display unit and the operation display unit of FIG. 3 (step S3).

この最大布量の表示がなされると、次いで駆動回路32が動作して駆動モータ5を駆動し、パルセータ4を回転させながら布量検知回路24の作用によって投入された布量が最大布量以下か否かを判断する(ステップS4)。そして、このステップS4で、投入された布量が最大布量以下と判断せれると、ステップはS5に移り、表示回路26の作用によって洗剤量目安表示部35に目安となる洗剤量を表示する(ステップS5)。その後、給水弁13を開いて給水を始め、ステップS6の10分コース運転を行う。   When the maximum cloth amount is displayed, the drive circuit 32 is then operated to drive the drive motor 5, and the cloth amount fed by the action of the cloth amount detection circuit 24 while rotating the pulsator 4 is less than the maximum cloth amount. Whether or not (step S4). Then, if it is determined in this step S4 that the inputted fabric amount is equal to or less than the maximum fabric amount, the step moves to S5, and the detergent amount guide display unit 35 displays the reference detergent amount by the action of the display circuit 26. (Step S5). Thereafter, the water supply valve 13 is opened to start water supply, and the 10-minute course operation in step S6 is performed.

一方、上記ステップS4で最大布量以下でないと判断されると、図示しないブザーを駆動して延長報知音を発信させ(ステップS7)、次いで、表示回路26が駆動して投入されている布量に応じた必要運転時間を運転時間表示部31に表示させるとともに洗剤量目安表示部35に目安となる洗剤量を表示する(ステップS8、S9)。そして、再度10分コース洗濯スイッチ34を押すことで給水弁13を開いて給水を始め、ステップS11の延長運転を行う。このとき、延長せずに洗濯量を減らして10分で洗濯を終わらせたい場合には、上記ステップS9で電源スイッチ18をOFFし、洗濯物を最大布量以下に押さえて、再度ステップS1から始めると良い。   On the other hand, if it is determined in step S4 that the amount is not less than the maximum amount of cloth, a buzzer (not shown) is driven to generate an extension notification sound (step S7), and then the amount of cloth that is input by driving the display circuit 26. The required operation time corresponding to the operation amount is displayed on the operation time display unit 31 and the detergent amount as a guide is displayed on the detergent amount guide display unit 35 (steps S8 and S9). Then, by pushing the course washing switch 34 again for 10 minutes, the water supply valve 13 is opened to start water supply, and the extended operation of step S11 is performed. At this time, if it is desired to reduce the amount of washing without extension and finish washing in 10 minutes, the power switch 18 is turned off in step S9, the laundry is held below the maximum amount of cloth, and again from step S1. Good to start.

図5は水道水の水量が少ない場合排水中に給水を行う洗濯機において、洗い及びすすぎ工程中に布の偏りを均一にするとともに洗剤濃度の希釈能力を一定以上にする作用を実行させるタイムチャートを示している。この図に示すように、所定の水量が水槽2内に確保され、排水弁9及び給水弁13が共にOFFして駆動モータ5の駆動で撹拌動作が実行されている洗いの動作モードにおいて時間t1になると、駆動回路32の作動で排水弁9及び給水弁13を共にONして給水と排水を同時に開始させるとともに駆動モータ5の駆動を停止してパルセータ4による撹拌を中断させる。   FIG. 5 is a time chart for executing the action of making the fabric unevenness uniform and making the detergent concentration dilution capacity a certain level or higher during the washing and rinsing process in a washing machine that supplies water during drainage when the amount of tap water is small. Is shown. As shown in this figure, a predetermined amount of water is ensured in the water tank 2, and both the drain valve 9 and the water supply valve 13 are turned OFF, and the stirring operation is executed by driving the drive motor 5. Then, both the drain valve 9 and the water supply valve 13 are turned ON by the operation of the drive circuit 32 to start water supply and drainage simultaneously, and the drive motor 5 is stopped to stop the stirring by the pulsator 4.

その結果、徐々に水槽2内の水量が減少して行き、そして、タイマ16dの時間カウントに従って所定時間が経過して時間t2になると、駆動回路32が再度作動して排水弁9のみをOFFするとともに駆動モータ5を再起動してパルセータ4を間欠回転させバランス動作(布の偏り均一化)を開始する。このバランス動作の実行期間中、給水弁13のON続行によって水槽2内の水量は徐々に増加して洗剤濃度が徐々に希釈されるとともにパルセータ4の回転に基づいて水槽2内の洗濯物が解され、固まっていた洗濯物が水槽2内全体に分散してバランスが取れた状態になって行く。   As a result, the amount of water in the water tank 2 gradually decreases, and when a predetermined time elapses according to the time count of the timer 16d and the time t2 is reached, the drive circuit 32 operates again to turn off only the drain valve 9. At the same time, the drive motor 5 is restarted, and the pulsator 4 is intermittently rotated to start the balance operation (uniform cloth unevenness). During the balance operation, the amount of water in the water tank 2 is gradually increased by continuing the ON of the water supply valve 13 so that the detergent concentration is gradually diluted and the laundry in the water tank 2 is dissolved based on the rotation of the pulsator 4. Then, the hardened laundry is dispersed throughout the aquarium 2 and becomes balanced.

そして、タイマ16dの経時動作に基づいて時間t3になると、バランス動作終了のタイミングとなり、上記駆動回路32が再度動作して上記排水弁9をONするとともに駆動モータ5を停止してパルセータ4の回転を止める。その後、時間t4において、給水弁13をOFFして給水を終了し、更に水槽2内に水が無くなったこと(排水終了)を検知したタイミングの時間t5において、駆動回路32の作動により、減速切換クラッチ7を脱水状態に切り替えるとともに駆動モータ5を再度ONして洗濯兼脱水槽3とパルセータ4を同時回転させ脱水動作を実行する。   When the time t3 is reached based on the time-dependent operation of the timer 16d, the timing for the end of the balance operation is reached. The drive circuit 32 operates again to turn on the drain valve 9 and stop the drive motor 5 to rotate the pulsator 4. Stop. After that, at time t4, the water supply valve 13 is turned off to finish water supply, and further, at time t5 when it is detected that water has disappeared in the water tank 2 (end of drainage), the drive circuit 32 is operated to switch the deceleration. The clutch 7 is switched to the dewatering state and the drive motor 5 is turned on again to rotate the washing and dewatering tub 3 and the pulsator 4 simultaneously to execute the dewatering operation.
