いから、検知回転数が通常よりも大きくなり、負荷量を
実際よりも少なく判断する慣れがある。(c) Problems to be solved by the invention In the conventional example, leftover hot water etc. from the bath are used,
If water has been supplied into the tank in advance to a level higher than the standard low water level, the load will naturally move more easily than when the water level is at the standard low level, so the detected rotation speed will be higher than normal and the load will be lower than the actual one. I'm used to making less judgments.
また、負荷量が比較的多い場合には、負荷の入れ方によ
って生ずる回転翼に対する抵抗の大小がばらつぎやすく
なり、検知精度が悪くなる問題がある。Furthermore, when the amount of load is relatively large, there is a problem that the resistance against the rotor blades tends to vary depending on how the load is applied, resulting in poor detection accuracy.
本発明は、斯かる問題点に鑑み、請求項１に記載の洗濯

また、本発明は、請求項２に記載の洗濯機に於いて、負
荷量を適切に判定するものである。Further, the present invention provides a washing machine according to claim 2, in which the load amount is appropriately determined.

成したものである。(d) Means for Solving the Problems The washing machine of the present invention is provided with water supplying water up to a predetermined standard water level in the water supply stage before the washing process, or at least in the case where the water supply has already exceeded the standard water level. With water supplied up to the reference water level in step 2, the rank of the load amount is determined based on the magnitude of the signal from the load detection means, and the water level for the washing process is determined according to the rank. In the load amount rank, compared to when judged using the reference water level,
The water level is configured to be higher when determined using the second reference water level.

る。Further, in the washing machine of the present invention, the load amount is determined based on the magnitude of data from the load detection means when water is supplied to a predetermined reference water level, and the load amount is determined to be relatively large based on the data. If it is within the range, the load amount is re-determined after water has been supplied to the second reference water level or after additional water has been supplied for a predetermined period of time.

荷量のランクを判定し、このランクに応じて洗い工程の
水位を決定する。(e) Effect: When water is supplied prior to the washing process, if the water level in the tank is below the standard water level, the rotor is rotated for a short time while the water is being supplied to the standard water level, and the load is applied depending on the rotation speed at that time. The rank of the amount is determined, and the water level in the washing process is determined according to this rank.
また、既に基準水位を越えている場合には、少なくとも
第２の基準水位まで給水した状態で、負荷量のランクを
判定し、−二の場合の洗い工程の水位は、基準水位で判
定した時よりも高くなるようにする。In addition, if the water level has already exceeded the standard water level, the load amount rank is determined with water supplied to at least the second standard water level, and the water level for the washing process in the case of -2 is determined based on the standard water level. Make it higher than that.

、まず槽内の水位が少量水位（優低水位）以下か否かを
判別しく５−１）、少量水位以下の場合には、−旦少量
水位まで給水しくＳ−２）、この状態で負荷量検知プロ
グラムを行なう（Ｓ−３）。When the laundry is put into the washing tub (4) and an appropriate program course is started, the microcomputer (25) first determines whether the water level in the tub is below the small water level (superior/low water level). 5-1) If the water level is below the small water level, water is first supplied to the small water level (S-2), and a load amount detection program is performed in this state (S-3).
前記負荷量検知プログラムは、第２図の通り、前記回転

荷量が大き、い程、回転翼（６）に対する抵抗が高いか
ら、短時間当りの回転数が小さくなる。従って、Ｎ≧Ｎ
１ならば負荷量少量（０，５陀未満） （Ｓ ６
） 、 Ｎ＋＞Ｎ≧Ｎ２ならば負荷量小（０，５〜１．
８ｋｇ未満＞ （Ｓ ７ ） 、Ｎ２＞Ｎ≧Ｎ、なら

ならば負荷量大（３ｋｇ〜） （Ｓ−９）と判定する。The load detection program, as shown in FIG.
). Then, this number of rotations N is stored in the ROM (reference values N1, N2, N3 in 281 (Nt>N2>N3
) to determine the load amount (laundry amount). That is, the larger the load, the higher the resistance to the rotor blade (6), and therefore the smaller the number of rotations per short time. Therefore, N≧N
If it is 1, the load amount is small (less than 0.5) (S 6
), if N+>N≧N2, the load amount is small (0,5 to 1.
Less than 8 kg> (S7), N2>N≧N, then medium load (1.8 to less than 3 kg) (S-8), N<N3
If so, it is determined that the load amount is large (3 kg or more) (S-9).
具体的には、前記回転翼（６）の反転周期：右０．６（

seconds) One stop 0.2 - Right 0.4 - Pause 0.2 - Right 0.4 -
Pause 0.2 - Right 0.4 = Body stop 0.2 - Left 0.6 Body stop 0
, 7. This is regarded as one cycle and is repeated within a short time T: 15 seconds. Also, N+: 158, N2: 143-157,
N,: 119-142.
さて、第１図に於いて、前記マイコン（２５）は、前記
負荷量検知プログラムで判定した負荷量が、大の時は水
位を「高」に設定しくＳ−１０）、中の時は水位を「中
」に設定しくＳ−１１）、小の時は水位を「小」に設定

ちに洗い工程に移行する。Now, in Fig. 1, the microcomputer (25) sets the water level to "high" when the load amount determined by the load amount detection program is large (S-10), and sets the water level to "high" when the load amount determined by the load amount detection program is medium (S-10). When the water level is set to "medium" (S-11), the water level is set to "small" (5-12), and when the water level is set to "medium" (S-14), the process immediately proceeds to the washing step.
そして、前記（Ｓ−１）に於いて、風呂の残り湯を利用

下か否かを判定しくＳ−１５）、否の場合は直ちに、才
な以下の場合は低水位まで給水してから（Ｓ−１６）、
第２図の負荷量検知プログラムを行なう（Ｓ−１７）。In the above (S-1), if more water than a small water level has been supplied into the tank in advance, such as by using the remaining hot water in the bath, the microcomputer (25) determines that the water level is low. Determine whether the water level is below the water level (S-15); if not, immediately; if the water level is below the water level, supply water to a low level (S-16);
The load amount detection program shown in FIG. 2 is executed (S-17).
而して、この時も、負荷量に応じて水位を決定するわけ
であるが、低水位又はそれ以上に給水されている場合に
は、少量水位の時に比べて、布が浮き上がって動き易く
なっているので、（Ｓ−３）の時に比べて負荷量を小さ
く判定してしまう、従って、低水位又はそれ以上給水さ
れている場合には、（Ｓ−１７＞で判定した負荷量に対
し、前記（Ｓ−３）で判定した時よりも１ランク上の水
位に設定する。尚、高水位以上の設定はできないので、
（Ｓ−１７）に於いて負荷量大と判定した時には、高水
位に設定する。At this time as well, the water level is determined according to the amount of load, but if water is being supplied at a low water level or higher, the cloth will float and move more easily than when the water level is small. Therefore, when water is being supplied at a low water level or above, the load amount is determined to be smaller than that determined in (S-3). Set the water level to one rank higher than the water level determined in (S-3) above.Please note that it is not possible to set the water level higher than the high water level.
When it is determined that the load amount is large in (S-17), a high water level is set.
以上の説明は負荷量を判定した場合のことであるが、同
様に負荷の質（木綿質Ｏｒ繊維質）を判定することらで
きる。The above explanation is about the case where the amount of load is determined, but the quality of the load (cotton or fibrous) can also be determined in the same way.
即ち、洗濯物は時間の経過に伴なって吸水し、その分回
転翼（６）に対する抵抗が高くなるが、この傾向は木綿
質である方が高い。従って、負荷量検知プログラム中、
回転翼（６）の回転一体止毎の回転数を検出し、例えば
１単位目と４単位目の回転数の差を見る。つまり、木綿
質である方が、この差が大きくなる。従って、この負荷
の質をも考慮して制御を行なってもよい。That is, the laundry absorbs water over time, and the resistance to the rotary blade (6) increases accordingly, and this tendency is higher when the laundry is made of cotton. Therefore, during the load detection program,
The number of rotations of the rotor blade (6) is detected every time the rotary blade (6) stops rotating, and the difference between the number of rotations of the first unit and the fourth unit, for example, is observed. In other words, this difference becomes larger when the material is made of cotton. Therefore, the quality of this load may also be taken into consideration when performing control.
尚、負荷の量や質のデータは、水位以外にも水流強度や
各工程時間の自動設定にも利用できる。In addition to the water level, the data on the quantity and quality of the load can also be used to automatically set the water flow intensity and each process time.
次に、本発明の池の実施例を、第６図に従って説明する
。Next, an embodiment of the pond according to the present invention will be described with reference to FIG.
洗い工程前の給水段階に於いて、前記マイコン（２５）

）。そして負荷量が少量であれば少量水位に（Ｓ−２２
＞ 、負薄量小であれば低水位に（Ｓ−２３）、負荷量
大であれば高水位に（Ｓ−２４）夫々設定する。In the water supply stage before the washing process, the microcomputer (25)
First, add a small amount of water to the water level in the tank (5-20), and then
Execute the load amount detection program as shown in the diagram (S-21
). If the load amount is small, the water level will be reduced to a small amount (S-22
> If the negative amount is small, the water level is set to low (S-23), and if the load amount is large, the water level is set to high (S-24).
さて、このように回転翼（６）（駆動モータ（７））に

がある。Now, in this method of determining the load amount based on the magnitude of the resistance applied to the rotary blade (6) (drive motor (7)),
When the amount of load is relatively large (large or medium load), the resistance to the rotor blade (6) becomes large or small depending on the method and quality of the load, which tends to cause variations in detection data and reduce detection accuracy. becomes worse, and compared to the actual load amount,
There is a risk of damaging the fabric if the water amount is set too low.
特に、負荷量大と判定した場合には、高水位に設定して
おけば、実質的に負荷量中であっても問題ないが、負荷
量中と判定した場合には、そのまま中水位に設定すれば
、実質的に負荷量大であった場合に、前述の不具合が生
じる。In particular, if the load is determined to be large, if the water level is set to a high level, there will be no problem even if the load is in the middle of the load, but if the load is determined to be medium, the water level is set to the medium level. Then, when the load amount is substantially large, the above-mentioned problem occurs.
そこで、負荷量中と判定した場合には、更に低水位まで

Compare with the reference value NA (N3<NA<N2)S-27), and if N>NA, set it to the middle water level.
-28), if N≦NA, it is determined that the resistance to the rotor (6) is still high, and a high water level is set.
そして、その陵は設定水位まで給水して（Ｓ−２９）、
洗い工程に移行する。Then, the tomb was supplied with water up to the set water level (S-29).
Move on to the washing process.
尚、本実施例に於いては、目安としてＮ、＝１５８、Ｎ

2=143, N5=82, and NA=129.
また、本実施例に於いて、第１回目の負荷検知プログラ

効果上望ましい。Further, in this embodiment, even if the first load detection program determines that the load amount is large, it is desirable to perform re-detection in terms of water saving effect.

い。この場合、負荷量が多い程１時間Ｔが長くなる。In addition, in the above embodiments, the load amount was determined based on the number of rotations of the rotor within a predetermined time, but it is also determined based on the length of the time T required for the rotor to reach a predetermined number of rotations. It's okay. In this case, the larger the load amount, the longer 1 hour T becomes.
