本発明は、洗い、すすぎ等の工程制御情報を得るための
洗濯機の洗濯物量検知装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a laundry amount detection device for a washing machine for obtaining process control information such as washing, rinsing, etc.
（従来の技術）
従来、洗濯物量検知装置を具備し、検知し之洗濯物量に
応じて洗い、すすぎ等の工程実行時間、水位及び水流、
さらには脱水時間等を自動的に制御するようにした洗濯
機が種々提案されており、洗濯物量検知装置も種々の方
式が提案されている。(Prior Art) Conventionally, a laundry amount detection device is provided, and the process execution time, water level, water flow, etc. of washing, rinsing, etc. is determined according to the detected amount of laundry.
Furthermore, various types of washing machines have been proposed that automatically control the spin-drying time, etc., and various types of laundry amount detection devices have also been proposed.
洗濯物量検知装置には攪拌翼に加わる負荷変動によって
変化する攪拌翼の回転速度若しくは回転数を利用する方
式があり、その−例として、攪拌翼を回転駆動してから
一定時間後の回転速度の変化を検知し、その回転速度の
平均値を求め、その平均値に基づいて洗濯物量を判定す
るようにした洗濯物量検知装置がある。There is a method of laundry amount detection device that uses the rotational speed or number of revolutions of the stirring blade, which changes depending on the load fluctuations applied to the stirring blade. There is a laundry amount detection device that detects the change, calculates the average value of the rotation speed, and determines the amount of laundry based on the average value.
（発明が解決しようとする問題点）
ところで、上記の従来方式のものでは、下記のような問
題を生じる。(Problems to be Solved by the Invention) However, the above-mentioned conventional system causes the following problems.
第８図は攪拌翼の回転速度の変化をモデル的に示した図

米方式により求めた平均値で、布のかたより等の影響を
大きく受けた値である。ａ２は同一布量で数多く測定し
て求めた平均値で、布のかたより等の影響の小さい値で
ある。このように、従来方式により求めた平均値は布の
かたより等によって大きくばらつくことになり、この平
均値に基づいて行なう洗濯物量の判定も正確性に欠ける
ことになる。FIG. 8 is a diagram showing a model change in the rotational speed of the stirring blade, and the explanation will be made according to this diagram. Now, if the rotational speed fluctuates greatly as shown in the third diagram due to fabric twisting occurring in the detection section set after a certain period of time (1) after the stirring blades start rotating, the conventional method The widely varying values are taken in as data and the average value of the rotational speed is determined. In FIG. 8, it is an average value obtained by the alU-based method, and is a value that is greatly affected by the bias of the cloth, etc. a2 is an average value obtained from many measurements using the same amount of cloth, and is a value that is less affected by factors such as the bias of the cloth. In this way, the average value determined by the conventional method varies greatly depending on the twist of the cloth, etc., and the determination of the amount of laundry based on this average value also lacks accuracy.
又、従来方式においても、長い時間に渡って回転速度を
検知してその平均値を求めるようにすれば、布のかたよ
り等の影響が小さくなり、洗濯物量の検知精度が高くな
るが、これでは検知のために必要以上に長い時間が要求
され、時間的に無駄を生じる。Also, in the conventional method, if the rotational speed is detected over a long period of time and the average value is calculated, the influence of cloth twist etc. will be reduced and the accuracy of detecting the amount of laundry will be increased. Detection requires a longer time than necessary, resulting in wasted time.
要するに、上記の従来方式では、短時間で常に検知精度
の高い洗濯物量検知を行なうことができなかった。In short, the conventional method described above cannot detect the amount of laundry with high detection accuracy in a short period of time.
然るに本発明にあっては、短時間で常に高い検知精度を
発揮できる洗濯物量検知装置を提供するものである。However, the present invention provides a laundry amount detection device that can consistently exhibit high detection accuracy in a short period of time.

瞬時変動値が基準値Ａ以下になるまで繰り返す。First, the flag 1'1irlJ of the average speed detection section 6 is set. Controller 8 then resets the timer,
The washing motor 3 is energized to rotate the agitating blades 2 for a certain period of time. During this time, the average speed detection unit 6 detects the instantaneous fluctuation value of the rotational speed of the stirring blade 2, and compares this value with the reference value A. If the instantaneous fluctuation value is greater than the reference value A, the motor starts.
It is determined that the sudden fluctuation is due to the twisting of the cloth, etc., and the flag 1 is set to ``I'', and the instantaneous fluctuation value is detected again and compared with the reference value A. Repeat until the instantaneous fluctuation value becomes less than the reference value A.

ている。When the instantaneous fluctuation value becomes less than the reference value A, flag 1 is set to "
Determine whether it is "l" or "0". If the flag l is "]", it is set as flag 1fjr:rOJ, and if it is "0", after memorizing the rotational speed of the stirrer blade 2 measured this time, measure the instantaneous fluctuation value again and perform the above comparison and judgment. repeat. here,
The reason for checking whether flag 1 is rlJ or "0" and determining whether it should be stored or not is that the instantaneous fluctuation value is based on only one degree at the inflection point of increase/decrease in rotational speed during sudden fluctuations due to twisting of the cloth, etc. This is because the value at this time is not taken in when the value becomes less than the value A, and the rotation speed is stored only when the instantaneous fluctuation value is determined to be less than the reference value A two or more times in a row.
従って、記憶される回転速度はモータ起動、布のかたよ
り等に関係のない安定期の値である。Therefore, the stored rotational speed is a value in a stable period that is unrelated to motor startup, cloth twisting, etc.

回転速度の平均値を求めることになる。この時の平均値
は、布のかたより等の影響を受けない値となる。After a certain period of time Ts has elapsed and the washing motor 3 is no longer energized, the average value of the rotational speeds stored while the washing motor 3 was energized is determined. The average value at this time is a value that is not affected by the twist of the cloth, etc.

行を制御することになる。Thereafter, the laundry amount conversion section 7 determines the amount of laundry based on the above-mentioned average value, and outputs a laundry amount signal according to the determination result. Then, the controller 8 determines the time, water flow, etc. of the washing process according to the signal, and controls the execution of the washing process.

By determining the amount of laundry, higher detection accuracy can be achieved.

うことができる。(Effects of the Invention) As described above, according to the present invention, the rotational speed or number of rotations of the agitating blade is stored, excluding values affected by the wobbling of the cloth, and the amount of laundry is calculated by calculating the average value of the values. By determining this, it is possible to always detect the amount of laundry with high accuracy even in a short period of time.
