FIG. 3 is a flowchart of the washing machine according to the second embodiment of the present invention, and shows a case where a course for washing the outer tub 12 and the inner tub 13 is washed. In addition, about the same component as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

図３において、スタートボタンが操作されると、制御手段２０は、外槽１２内に給水する第１給水工程（ステップＳ１）を行なう。第１給水工程（ステップＳ１）においては、制御手段２０は、施錠手段１８により蓋体１７を施錠し、外槽１２内に一定水位まで給水する。   In FIG. 3, when the start button is operated, the control means 20 performs a first water supply step (step S1) for supplying water into the outer tub 12. In the first water supply step (step S1), the control means 20 locks the lid body 17 by the locking means 18 and supplies the water into the outer tub 12 to a certain water level.

外槽１２内の水位が一定水位に達すると、制御手段２０は、待機工程（ステップＳ２）を行なう。待機工程（ステップＳ２）においては、制御手段２０は、施錠手段１８による蓋体１７の施錠を解除し、使用者により蓋体１７が開放され、外槽１２及び内槽１３に付着した黒カビや汚れ等を落とすための洗剤を投入した後、蓋体１７が閉塞されるまで待機する。   When the water level in the outer tub 12 reaches a certain water level, the control means 20 performs a standby step (step S2). In the standby step (step S2), the control means 20 releases the locking of the lid 17 by the locking means 18, the lid 17 is opened by the user, and black mold and dirt adhering to the outer tub 12 and the inner tub 13. After putting in the detergent for dropping etc., it waits until the cover body 17 is obstruct | occluded.

待機工程（ステップＳ２）は、外槽１２内に水がない状態で漂白剤等の強いアルカリ性の洗剤が投入されると、外槽１２、内槽１３及び攪拌翼１４が傷んでしまう虞があるため、外槽１２内に一定水位まで給水し、外槽１２内に一定水位の水がある状態で、施錠手段１８により蓋体１７の施錠を解除して、使用者による洗剤の投入が行なわれるまで待機する工程である。   In the standby process (step S2), if a strong alkaline detergent such as a bleaching agent is introduced in the absence of water in the outer tank 12, the outer tank 12, the inner tank 13, and the stirring blade 14 may be damaged. Therefore, water is supplied to the outer tub 12 to a certain water level, and the lock 17 is unlocked by the locking means 18 in a state where there is water at the certain water level in the outer tub 12, and the user puts in the detergent. It is a process of waiting until.

待機工程（ステップＳ２）において、制御手段２０は、蓋体１７が開放され、再び閉塞されるのを蓋体開閉検知手段１９が検知すると、第２給水工程（ステップＳ３）を行う。
第２給水工程（ステップＳ３）においては、蓋体１７を施錠手段１８により施錠し、外槽１２内に第１給水工程（ステップＳ１）における一定水位より高い所定水位まで給水する。 In the standby step (step S2), the control means 20 performs the second water supply step (step S3) when the lid body opening / closing detection means 19 detects that the lid body 17 is opened and closed again.
In the second water supply step (step S3), the lid 17 is locked by the locking means 18, and water is supplied into the outer tub 12 to a predetermined water level higher than the constant water level in the first water supply step (step S1).

第２給水工程（ステップＳ３）において、外槽１２内の水位が所定水位に達すると、制御手段２０は、攪拌工程（ステップＳ４）を行なう。攪拌工程（ステップＳ４）においては、モータ１５を駆動し、内槽１３と攪拌翼１４を選択的に回転させ、外槽１２、内槽１３及び攪拌翼１４を洗浄する。   In the second water supply step (step S3), when the water level in the outer tub 12 reaches a predetermined water level, the control means 20 performs a stirring step (step S4). In the stirring step (step S4), the motor 15 is driven to selectively rotate the inner tank 13 and the stirring blade 14 to clean the outer tank 12, the inner tank 13 and the stirring blade 14.

本実施の形態においては、待機工程（ステップＳ２）において、蓋体１７の施錠状態を維持して蓋体１７の不用意な開放を阻止するチャイルドロック機能を有している。チャイルドロック機能を設定した状態の待機工程（ステップＳ２）においては、チャイルドロック機能を解除すると、制御手段２０が施錠手段１８を解除し、蓋体１７の開放が可能となる。   In the present embodiment, in the standby step (step S2), a child lock function for maintaining the locked state of the lid body 17 and preventing inadvertent opening of the lid body 17 is provided. In the standby process (step S2) in the state where the child lock function is set, when the child lock function is released, the control means 20 releases the locking means 18 and the lid 17 can be opened.

待機工程（ステップＳ２）において、チャイルドロック機能による蓋体１７の施錠状態で、使用者が蓋体１７を開放しようとした場合、施錠手段１８及び蓋体開閉検知手段１９の配設位置、蓋体１７に加わる力の場所や方向等により、施錠された状態の蓋体１７の一部が浮き上がり、蓋体開閉検知手段１９が蓋体１７の開放を誤検出し、第２給水工程（ステップＳ３）に移行する虞がある。   In the standby step (step S2), when the user tries to open the lid 17 in the locked state of the lid 17 by the child lock function, the arrangement position of the locking means 18 and the lid opening / closing detection means 19, the lid Depending on the location and direction of the force applied to 17, a part of the lid body 17 in the locked state is lifted, and the lid body opening / closing detection means 19 erroneously detects the opening of the lid body 17, and the second water supply step (step S 3) There is a risk of moving to.

本実施の形態では、蓋体開閉判定手段２１は、施錠手段１８から蓋体１７の閉塞状態を検出する蓋体閉信号を入力する状態では、蓋体開閉検知手段１９から蓋体開放検出信号が入力された時、蓋体開放検出信号を取り消し、制御手段２０に蓋体閉信号を出力する。従って、施錠手段１８による蓋体１７の施錠状態で、蓋体開閉検知手段１９が蓋体１７の開放を検出した場合でも、蓋体１７の開放状態の誤検出を防止できる。   In the present embodiment, the lid opening / closing determination means 21 receives the lid opening detection signal from the lid opening / closing detection means 19 when the lid closing signal for detecting the closing state of the lid 17 is input from the locking means 18. When input, the lid opening detection signal is canceled and the lid closing signal is output to the control means 20. Therefore, even when the lid opening / closing detection means 19 detects the opening of the lid 17 in the locked state of the lid 17 by the locking means 18, it is possible to prevent erroneous detection of the opened state of the lid 17.

図４は、本発明の第３の実施の形態における洗濯機のフローチャートであり、洗濯物の偏り等による脱水不良時の処理を示している。なお、第１の実施形態と同一部品は同一符号を付して説明を省略する。 (Embodiment 3)
FIG. 4 is a flowchart of the washing machine according to the third embodiment of the present invention, and shows a process at the time of poor dehydration due to the bias of the laundry. The same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

図４において、制御手段２０は、外槽１２から洗濯水を排水する排水工程（ステップＳ５）を行なう。排水工程（ステップＳ５）においては、施錠手段１８は、蓋体１７を施錠した状態である。   In FIG. 4, the control means 20 performs the drainage process (step S5) which drains wash water from the outer tub 12. In the draining step (step S5), the locking means 18 is in a state where the lid 17 is locked.

外槽１２内の洗濯水の排水が完了すると、制御手段２０は、脱水工程（ステップＳ６）を行ない、洗濯物を脱水する。脱水工程において、内槽１３内の洗濯物に偏りがあると、洗濯機の振動、騒音が大きくなるため、内槽１３を高速で回転させることが困難な状態となる。このような状態となった場合には、制御手段２０は、内槽１３の回転を停止し、待機工程（ステップＳ７）に移行する。   When draining of the washing water in the outer tub 12 is completed, the control means 20 performs a dehydration step (step S6) to dehydrate the laundry. In the dehydration process, if the laundry in the inner tub 13 is biased, vibration and noise of the washing machine increase, and it becomes difficult to rotate the inner tub 13 at high speed. When it becomes such a state, the control means 20 stops rotation of the inner tank 13, and transfers to a standby process (step S7).

待機工程（ステップＳ７）においては、制御手段２０は、施錠手段１８による蓋体１７の施錠を解除し、警報により使用者に洗濯物の偏りの解消を促す。待機工程において、蓋体１７が開放され、再び閉塞されたことを蓋体開閉検知手段１９が検知すると、制御手段２０は、再度脱水工程（ステップＳ６）に移行する。   In the standby step (step S7), the control means 20 releases the locking of the lid 17 by the locking means 18, and prompts the user to eliminate the bias of the laundry by an alarm. In the standby process, when the lid body opening / closing detection means 19 detects that the lid body 17 is opened and closed again, the control means 20 proceeds to the dehydration process (step S6) again.

本実施の形態においては、待機工程（ステップＳ７）において、洗濯運転中における蓋体１７の施錠状態を維持して蓋体１７の不用意な開放を阻止するチャイルドロック機能を有している。チャイルドロック機能を設定した状態の待機工程（ステップＳ７）において
は、チャイルドロック機能を解除すると、制御手段２０が施錠手段１８を解除し、蓋体１７の開放が可能となる。 In the present embodiment, the standby process (step S7) has a child lock function that keeps the lid 17 locked during the washing operation and prevents the lid 17 from being unintentionally opened. In the standby step (step S7) in a state where the child lock function is set, when the child lock function is released, the control means 20 releases the locking means 18 and the lid 17 can be opened.

待機工程（ステップＳ７）において、チャイルドロック機能による蓋体１７の施錠状態で、蓋体１７を開放しようとした場合、施錠手段１８及び蓋体開閉検知手段１９の配設位置、蓋体１７に加わる力の場所や方向等により、施錠された状態の蓋体１７の一部が浮き上がり、蓋体開閉検知手段１９が蓋体１７の開放を誤検出し、洗濯物の偏りが解消されていないにもかかわらず、脱水工程（ステップＳ６）に移行する虞がある。   In the standby process (step S7), when the lid 17 is to be opened while the lid 17 is locked by the child lock function, the position where the locking means 18 and the lid opening / closing detection means 19 are disposed and the lid 17 are added. Depending on the location and direction of the force, a part of the lid body 17 in the locked state is lifted, and the lid body opening / closing detection means 19 erroneously detects the opening of the lid body 17 and the bias of the laundry has not been eliminated. Regardless, there is a risk of shifting to the dehydration step (step S6).

本実施の形態では、蓋体開閉判定手段２１は、施錠手段１８から蓋体１７の閉塞状態を検出する蓋体閉信号を入力する状態では、蓋体開閉検知手段１９から蓋体開放検出信号が入力された時、蓋体開放検出信号を取り消し、制御手段２０に蓋体閉信号を出力する。従って、施錠手段１８による蓋体１７の施錠状態で、蓋体開閉検知手段１９が蓋体１７の開放を検出した場合でも、蓋体１７の開放状態の誤検出を防止できる。   In the present embodiment, the lid opening / closing determination means 21 receives the lid opening detection signal from the lid opening / closing detection means 19 when the lid closing signal for detecting the closing state of the lid 17 is input from the locking means 18. When input, the lid opening detection signal is canceled and the lid closing signal is output to the control means 20. Therefore, even when the lid opening / closing detection means 19 detects the opening of the lid 17 in the locked state of the lid 17 by the locking means 18, it is possible to prevent erroneous detection of the opened state of the lid 17.

The lid 17 is maintained in the locked state by the locking means 18 as in the standby step (step S7) in the embodiment.

チャイルドロック機能による蓋体１７の施錠状態において、蓋体１７を開放しようとした場合、施錠手段１８及び蓋体開閉検知手段１９の配設位置、蓋体１７に加わる力の場所や方向等により、施錠された状態の蓋体１７の一部が浮き上がり、蓋体開閉検知手段１９が蓋体１７の開放を誤検出する虞がある。   When the lid 17 is to be opened in the locked state of the lid 17 by the child lock function, depending on the arrangement position of the locking means 18 and the lid opening / closing detection means 19, the location and direction of the force applied to the lid 17, etc. There is a possibility that a part of the lid 17 in the locked state is lifted, and the lid opening / closing detection means 19 erroneously detects the opening of the lid 17.

本実施の形態では、蓋体開閉判定手段２１は、施錠手段１８から蓋体１７の閉塞状態を検出する蓋体閉信号を入力する状態では、蓋体開閉検知手段１９から蓋体開放検出信号が入力された時、蓋体開放検出信号を取り消し、制御手段２０に蓋体閉信号を出力する。従って、施錠手段１８による蓋体１７の施錠状態で、蓋体開閉検知手段１９が蓋体１７の開放を検出した場合でも、蓋体１７の開放状態の誤検出を防止できる。   In the present embodiment, the lid opening / closing determination means 21 receives the lid opening detection signal from the lid opening / closing detection means 19 when the lid closing signal for detecting the closing state of the lid 17 is input from the locking means 18. When input, the lid opening detection signal is canceled and the lid closing signal is output to the control means 20. Therefore, even when the lid opening / closing detection means 19 detects the opening of the lid 17 in the locked state of the lid 17 by the locking means 18, it is possible to prevent erroneous detection of the opened state of the lid 17.

また、蓋体開閉判定手段２１は、制御手段２０に報知信号を出力し、制御手段２０は、報知信号の入力により報知手段２２を作動させてブザー音やメロディ等を発生させ、使用者にチャイルドロック機能により蓋体１７が閉塞状態であることを警告する。   The lid opening / closing determination means 21 outputs a notification signal to the control means 20, and the control means 20 activates the notification means 22 in response to the input of the notification signal to generate a buzzer sound, a melody, etc. The lock function warns that the lid 17 is closed.

なお、本実施の形態は、縦型洗濯機を用いて説明したが、ドラム式洗濯機に用いることもでき、縦型洗濯機に限定するものではない。   In addition, although this Embodiment demonstrated using the vertical washing machine, it can also be used for a drum-type washing machine and is not limited to a vertical washing machine.

以上のように、本発明にかかる洗濯機は、施錠手段による蓋体の施錠状態で、蓋体開閉検知手段が蓋体の開放を検出した場合でも、蓋体の開放状態の誤検出を防止でき、ドラム式洗濯機等の用途にも適用できる。   As described above, the washing machine according to the present invention can prevent erroneous detection of the lid open state even when the lid opening / closing detection means detects the lid opening in the locked state of the lid by the locking means. It can also be applied to uses such as drum-type washing machines.
