【発明の属する技術分野】
本発明は、洗濯機に関する。
【0002】
【従来の技術】
一般に、洗濯機においては、予約洗濯運転機能があり、予約洗濯運転スタートキーの操作により、その後実際の洗濯運転実行時点になると、自動的に洗濯運転が実行される。この場合、予約洗濯運転スタートキーの操作から実際の洗濯運転実行時点までの間に小さな子供が誤って洗濯槽内に落ちると、気づかれること無く洗濯運転実行時点になったときに自動的に洗濯が実行されてしまう恐れがある。
【0003】
また、予約洗濯運転でない場合であっても、予め例えば前日に洗濯槽内に洗濯物と洗剤を投入しておいて翌日朝に洗濯運転スタートキー操作を行う場合、洗濯槽内に誤って子供が落ちて蓋が閉じられていると、そのままスタートキー操作をして洗濯を実行してしまう恐れがある。
【0004】
特に、蓋前開きタイプのドラム式全自動洗濯乾燥機においては、洗濯槽内に対する洗濯物出し入れ口が低い位置にあり、子供が誤って洗濯槽内に落ちやすく、この状態で洗濯が実行される恐れが増す。また、全自動洗濯乾燥機では、乾燥も実行されるため、特に問題である。
【0005】
【発明が解決しようとする課題】
本発明は、洗濯槽内に子供が誤って落ちたことに気づくことなく洗濯が実行されてしまうのを抑制できる洗濯機を提供しようとするものである。
【0006】
【課題を解決するための手段および発明の効果】

【0007】
また、本発明の洗濯機は、ハウジングと、このハウジング内に配置された洗濯槽と、この洗濯槽に対する洗濯物の出し入れを可能とするために前記ハウジングに設けられた洗濯物出し入れ口と、この洗濯物出し入れ口を開閉する蓋と、前記洗濯槽の異常振動及びまたは異常重心移動を検知する異常検知器と、予約洗濯運転スタート操作時から実際に洗濯運転が実行されるまでの間の非洗濯運転時に、前記異常検知器が前記洗濯槽の異常振動及びまたは異常重心移動を検知したとき、その後の実際の洗濯運転の実行を禁止する制御部とを備えたことを特徴とする。
【0008】
本発明の構成によれば、事前に洗濯物や洗剤を洗濯槽内に入れておき追って洗濯運転スタートキーを操作して洗濯運転を実行させる場合や、予約洗濯運転スタートキーの操作により追って予約運転開始時点が到来した時点で自動的に洗濯運転を開始させる場合、実際の洗濯運転までの間に子供が誤って洗濯槽内に落ちると、洗濯槽が大きく異常振動する。或いは、洗濯槽の重心が異常に移動する。すると、異常検知器がこの異常振動や異常重心移動を検知して子供が洗濯槽内に落ちたことを検知し、その後の洗濯運転スタートキーの操作による洗濯運転の実行が禁止される。或いは、その後に予約運転開始時点が到来しても、実際の洗濯運転の実行が禁止される。
【0009】
【発明の実施の形態】
図1及び図2は本発明実施例のドラム式全自動洗濯乾燥機の正面断面図及び側面断面図である。洗濯機のハウジング10内に洗濯槽2が配置されており、この洗濯槽2内には回転自在に洗濯ドラム11が配置されている。洗濯ドラム11は、洗濯時は低速回転し、脱水時は高速回転し、脱水後の乾燥時には低速回転する。このとき、洗濯槽2は揺れるが、この揺れを吸収するために防振装置12が設けられている。そして、この防振装置12には、洗濯槽2の異常振動及びまたは異常重心移動を検知する異常検知器である異常検知センサ1(重量センサ、偏心センサ等)が設けられている。
【0010】
前記ハウジング10の前面には洗濯槽2に対する洗濯物の出し入れを可能とするために洗濯物出し入れ口13が形成されており、この洗濯物出し入れ口13は蓋3にて開閉される。また、洗濯槽2の後側には洗濯ドラム11を回転するダイレクトドライブモータ4が設けられている。

Generally, the washing machine has a reserved washing operation function, and when the actual washing operation execution time is reached by operating a reserved washing operation start key, the washing operation is automatically executed. In this case, if a small child accidentally falls into the washing tub during the period from the operation of the reserved washing operation start key to the actual execution of the washing operation, the washing operation is automatically carried out without being noticed. May be executed.
[0003]
Further, even when the washing operation is not the reserved washing operation, for example, if the laundry and detergent are put in the washing tub the day before and the washing operation start key is operated the next morning, a child may be mistakenly put in the washing tub. If the lid has fallen and the lid is closed, the user may operate the start key and perform washing.
[0004]
In particular, in a drum type fully automatic washing / drying machine of a front lid type, a laundry outlet / inlet with respect to the inside of a washing tub is located at a low position, and a child is likely to fall into the washing tub by mistake, and washing is performed in this state. Fear increases. Further, in a fully automatic washing and drying machine, drying is also performed, which is a particular problem.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a washing machine capable of suppressing the execution of washing without noticing that a child has fallen into a washing tub by mistake.
[0006]
Means for Solving the Problems and Effects of the Invention
In order to achieve the above object, a washing machine according to the present invention includes a housing, a washing tub disposed in the housing, and a laundry provided in the housing to enable the laundry to be taken in and out of the washing tub. An access port, a lid for opening and closing the laundry access port, an abnormality detector for detecting abnormal vibration of the washing tub and / or an abnormal center of gravity shift, and an abnormal vibration of the washing tub during non-washing operation. And / or a control unit for prohibiting the subsequent execution of the washing operation when the abnormal center of gravity shift is detected.
[0007]
In addition, the washing machine of the present invention includes a housing, a washing tub disposed in the housing, a laundry access port provided in the housing for allowing the laundry to be taken in and out of the washing tub, A lid for opening and closing the laundry door, an abnormality detector for detecting abnormal vibration and / or abnormal center-of-gravity movement of the washing tub, and a non-washing operation from the time of starting the reserved washing operation until the actual washing operation is performed. A control unit for prohibiting the subsequent execution of the actual washing operation when the abnormality detector detects abnormal vibration and / or abnormal movement of the center of gravity of the washing tub during operation.
[0008]
According to the configuration of the present invention, when the laundry or detergent is put in the washing tub in advance and the laundry operation is started by operating the laundry operation start key, or the reserved operation is performed later by operating the reserved laundry operation start key. When the washing operation is automatically started at the time when the start time has arrived, if the child accidentally falls into the washing tub before the actual washing operation, the washing tub vibrates greatly and abnormally. Alternatively, the center of gravity of the washing tub moves abnormally. Then, the abnormality detector detects the abnormal vibration and abnormal movement of the center of gravity to detect that the child has fallen into the washing tub, and the subsequent execution of the washing operation by operating the washing operation start key is prohibited. Alternatively, even if the scheduled operation start time comes later, the actual execution of the washing operation is prohibited.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
1 and 2 are a front sectional view and a side sectional view of a drum-type fully automatic washing and drying machine according to an embodiment of the present invention. A washing tub 2 is arranged in a housing 10 of the washing machine, and a washing drum 11 is rotatably arranged in the washing tub 2. The washing drum 11 rotates at a low speed during washing, rotates at a high speed during spin-drying, and rotates at a low speed during drying after spin-drying. At this time, the washing tub 2 shakes, and a vibration isolator 12 is provided to absorb the shaking. The vibration isolator 12 is provided with an abnormality detection sensor 1 (weight sensor, eccentricity sensor, etc.) which is an abnormality detector for detecting abnormal vibration of the washing tub 2 and / or abnormal movement of the center of gravity.
[0010]
On the front surface of the housing 10, a laundry outlet 13 is formed to allow the laundry to be taken in and out of the washing tub 2. The laundry outlet 13 is opened and closed by the lid 3. A direct drive motor 4 for rotating the washing drum 11 is provided on the rear side of the washing tub 2.
[0011]
FIG. 3 is a block circuit diagram of the washing machine. The control means (control unit) 14 controls the direct drive motor based on the output of the abnormality detection sensor 1, the reservation time during the reservation washing operation set by the reservation timer device 15, and the washing conditions set by a key (not shown). 4 and the notifying unit 16 is drive-controlled.
[0012]
FIG. 4 is a flowchart showing the control by the control means 14 for performing the reserved washing operation. During the non-washing operation (for example, from the time when the reserved washing operation start key is operated to the time when the reserved standby time elapses and before the actual washing operation is performed), the abnormality detection sensor 1 causes abnormal vibration or abnormality. If the movement of the center of gravity is not detected, the washing operation process is executed when the reservation standby time has elapsed. On the other hand, if the child accidentally falls into the washing tub 2 during the non-washing operation, a large force is suddenly applied to the washing tub 2 and the washing tub 2 abnormally vibrates. Alternatively, the center of gravity of the washing tub 2 moves abnormally when a child falls into the washing tub 2. The center of gravity of the washing tub 2 moves abnormally even when a child moves in the washing tub 2. Then, when the abnormality is detected by the abnormality detection sensor 1, the notification unit 16 notifies the abnormality, and the subsequent washing operation (reserved washing operation) is prohibited (stopped).
[0013]
FIG. 5 is another flowchart showing the control by the control means 14 for performing the reserved washing operation. Only differences from FIG. 4 will be described. If an abnormality is detected during the non-washing operation, the occurrence of the abnormality is recorded, and the abnormality is notified based on the record of the abnormality when the reservation standby time has elapsed. At 16, the subsequent washing operation (reserved washing operation) is prohibited (stopped).
[0014]
Note that the above-described washing machine has a function of determining a water level according to the amount of laundry, and a water level corresponding to the detected amount of laundry is displayed using an LED that also displays a laundry course. .
[0015]
The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims.
