As an example, it is considered that a washing operation with warm water is performed a plurality of times (for example, , See Patent Document 1). The washing machine described in Patent Document 1 performs the first pickling and washing (washing water is 40 ° C., motor driven for 2 seconds, motor stopped for 88 seconds), and the second high temperature washing is performed at 60 ° C. for washing water. The stirring operation is the same as that for pickling. In addition, it is considered that the first washing process of the washing (drum rotation speed is 50 rpm) and the second washing process of the squeeze washing (drum rotation speed is 300 rpm) are alternately performed. (For example, refer to Patent Document 2).

The temperature of the water reservoir 11 is detected by temperature detection means 13 such as a thermistor.

水槽２内の水溜部１１に溜められた洗濯水は、循環水路１４に設けた循環手段としてのポンプ１５によってドラム３内へ循環させることができる。水溜部１１の底部に循環水路１４と連通した洗濯水を吸い込む吸い込み部１６を設け、ドラム３の前面側に設けた開口部６の上部に、ドラム３内に向けて洗濯水が吐出されるように吐出部１７を設けている。   Washing water stored in the water reservoir 11 in the water tank 2 can be circulated into the drum 3 by a pump 15 as a circulation means provided in the circulation water channel 14. A suction part 16 for sucking washing water communicating with the circulation water channel 14 is provided at the bottom of the water reservoir 11 so that the washing water is discharged toward the inside of the drum 3 at the upper part of the opening 6 provided on the front side of the drum 3.

以上のように構成されたドラム式洗濯機について、以下その動作、作用を説明する。洗濯は、洗い、すすぎ、脱水の各工程からなり、洗い工程について、図４および図５により
説明する。 About the drum type washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Laundry includes washing, rinsing, and dehydration processes. The washing process will be described with reference to FIGS.

まず、筐体１の前面側に開閉自在に設けた扉２１を開いて開口部６からドラム３内に洗濯物を投入した後、操作部２２の電源スイッチ（図示せず）をオンし、スタートスイッチ（図示せず）を操作して運転を開始する。洗い工程がスタート（ステップ１００）すると、布量検知手段２３によってドラム３内に投入された洗濯物の量を検知する（ステップ１０１）。   First, after opening the door 21 which can be opened and closed on the front side of the housing 1 and putting the laundry into the drum 3 from the opening 6, the power switch (not shown) of the operation unit 22 is turned on to start A switch (not shown) is operated to start operation. When the washing process starts (step 100), the amount of laundry put into the drum 3 is detected by the cloth amount detecting means 23 (step 101).

制御手段２０は、ドラム３を例えば５０ｒｐｍで正逆回転させ、モータ７のトルクの大小によって、予め設定した布量のテーブル（図示しない）と照し合せて、ドラム３内の洗濯物の量を検知する。ドラム３の回転数は、一般的な回転数検知手段２４によって検知され、制御手段２０に入力される。   The control means 20 rotates the drum 3 forward and backward at, for example, 50 rpm, and compares the amount of laundry in the drum 3 with a predetermined cloth amount table (not shown) according to the torque of the motor 7. Detect. The rotation speed of the drum 3 is detected by a general rotation speed detection unit 24 and input to the control unit 20.

次に、ドラム３を例えば５０ｒｐｍで正転方向に回転させ（ステップ１０２）、検知した布量に応じて設定された水量を洗剤ケース１０内の洗剤を流しながら水槽２内に給水する（ステップ１０３）。給水量は投入される布量に応じてあらかじめ設定されており、洗剤ケース１０内に投入された洗剤とともに水槽２内に洗濯水が給水されるとともに、水位検知手段２５により設定量の洗濯水が給水されたことを検知すると（ステップ１０４）、給水弁８を閉じて給水を停止する（ステップ１０５）。   Next, the drum 3 is rotated in the forward direction, for example, at 50 rpm (step 102), and the amount of water set according to the detected cloth amount is supplied into the aquarium 2 while the detergent in the detergent case 10 is flowing (step 103). ). The amount of water supply is set in advance according to the amount of cloth to be supplied. Washing water is supplied into the aquarium 2 together with the detergent supplied into the detergent case 10, and a set amount of washing water is supplied by the water level detection means 25. When it is detected that water has been supplied (step 104), the water supply valve 8 is closed to stop water supply (step 105).

次に、ヒータ１２に通電して水槽２内の洗濯水を加熱し（ステップ１０６）、設定された水温に到達したか否かを温度検知手段１３により検知する（ステップ１０７）。設定温度に加熱されるとヒータ１２の通電を停止する（ステップ１０８）。   Next, the heater 12 is energized to heat the wash water in the water tub 2 (step 106), and the temperature detecting means 13 detects whether or not the set water temperature has been reached (step 107). When heated to the set temperature, the energization of the heater 12 is stopped (step 108).

洗い工程は、最初に遠心洗いを実行する（ステップ１０９）。遠心洗いは、ドラム３の回転数を例えば２００ｒｐｍに設定し、時間ｔ１は３０秒とする。ドラム３を矢印イ方向へ高速で回転させると、図５（ａ）に示すように、洗濯物が遠心力によってドラム３の内周面に張り付いた状態になり、この遠心力の作用により、洗濯物に含まれている洗濯水とともに、洗濯物の繊維中から汚れを効果的に除去することができる。なお、ドラム３の回転数は、共振周波数以下の３００ｒｐｍ付近でも同等の効果が得られる。   In the washing step, centrifugal washing is first executed (step 109). In centrifugal washing, the rotation speed of the drum 3 is set to 200 rpm, for example, and the time t1 is set to 30 seconds. When the drum 3 is rotated in the direction of arrow A at high speed, as shown in FIG. 5A, the laundry is stuck to the inner peripheral surface of the drum 3 by centrifugal force. Along with the washing water contained in the laundry, dirt can be effectively removed from the fibers of the laundry. The same effect can be obtained even when the rotational speed of the drum 3 is around 300 rpm, which is equal to or lower than the resonance frequency.

遠心洗いを時間ｔ１実行した後、漬け置き洗いを時間ｔ２実行する（ステップ１１０）。漬け置き洗いは、ドラム３を矢印イ方向へ１０秒間２０ｒｐｍで回転駆動した後、１２０秒停止する。漬け置き洗いの最初に、ドラム３を例えば２０ｒｐｍの低速で回転させることにより、ドラム３の内周面に張り付いた洗濯物を下方へ落下させるとともに、図５（ｂ）に示すように、バッフル４で回転方向イへ持ち上げられた洗濯物が低い位置から落下し、ドラム３の底部を転がるように動作する。   After centrifugal washing is performed for time t1, soaking is performed for time t2 (step 110). The pickling and washing is stopped for 120 seconds after the drum 3 is rotationally driven in the direction of arrow A at 20 rpm for 10 seconds. At the beginning of the soaking, the drum 3 is rotated at a low speed of 20 rpm, for example, so that the laundry stuck to the inner peripheral surface of the drum 3 is dropped downward, and as shown in FIG. 4, the laundry lifted in the rotational direction (a) falls from a low position and operates to roll on the bottom of the drum 3.

これにより、洗濯水の溜まったドラム３の底部で、洗濯物の位置を移動させることができ、また、洗濯物がほぐされて、洗濯水を効果的に洗濯物に浸透させることができ、漬け置き洗いの効果を高めることができる。なお、漬け置き洗いのドラム３の回転数は、１５〜３０ｒｐｍでも同等の効果が得られる。   As a result, the position of the laundry can be moved at the bottom of the drum 3 where the washing water is accumulated, and the laundry can be loosened so that the washing water can effectively penetrate into the laundry. The effect of washing up can be increased. In addition, the same effect is acquired even if the rotation speed of the drum 3 for pickling is 15-15 rpm.

遠心洗い（時間ｔ１）と漬け置き洗い（時間ｔ２）は、交互に繰り返し実行され、３０分継続する。ｔ１＋ｔ２の１サイクルが１６０秒の場合、遠心洗いと漬け置き洗いを、交互に約１１回繰り返えした後、叩き洗いを実行する（ステップ１１１）。   Centrifugal washing (time t1) and soaking (time t2) are repeatedly performed alternately and continue for 30 minutes. When one cycle of t1 + t2 is 160 seconds, centrifugal washing and soaking are alternately repeated about 11 times, and then tapping is performed (step 111).

叩き洗いは、ドラム３を例えば５０ｒｐｍで正逆回転させ、洗濯物をバッフル４で回転方向へ持ち上げ、ドラム３内の高い位置から落下させて機械力を作用させることにより、汚れを除去する効果を高めることができる。洗い工程を終了（ステップ１１２）後、すす
ぎ工程、脱水工程へと移行する。 For example, the drum washing is performed by rotating the drum 3 forward and backward at 50 rpm, lifting the laundry in the rotation direction by the baffle 4, dropping it from a high position in the drum 3, and applying a mechanical force to remove dirt. Can be increased. After finishing the washing process (step 112), the process proceeds to a rinsing process and a dehydrating process.

以上のように、本実施の形態においては、筐体１内に弾性支持した水槽２と、水槽２内に回転可能に設けられたドラム３と、ドラム３を回転駆動するモータ７と、水槽２に洗濯水を給水する給水手段８と、水槽２内の洗濯水を加熱する加熱手段１２と、水槽２内の洗濯水の温度を検知する温度検知手段１３と、水槽２内の洗濯水の水位を検知する水位検知手段２５と、モータ７等を制御し、洗い、すすぎ、脱水等の工程を制御する制御手段２０とを備え、制御手段２０は、洗い工程において、水槽２内の洗濯水を所定の温度に加熱し、ドラム３内の洗濯物がドラム３の内周面に張り付く遠心洗いと、ドラム３の駆動と停止を含む漬け置き洗いを、交互に所定時間繰り返すようにしたものであり、ドラム３内の洗濯物に加熱された洗濯水を浸透させ、洗濯水に含まれた洗剤成分を繊維に付着している汚れに効果的に作用させることができるとともに、遠心効果によって汚れを洗濯水とともに繊維中から除去し、洗濯物の繊維中の洗濯水の置換を加速して汚れ物質の除去が促進されることにより、汚れ落ちをよくして洗浄効果を高めることができる。   As described above, in the present embodiment, the water tank 2 elastically supported in the housing 1, the drum 3 rotatably provided in the water tank 2, the motor 7 that rotationally drives the drum 3, and the water tank 2.
