この慣性パルス数は負荷量すなわち洗濯物の布量や水量
によって異なり、負荷が小さい程パルス数が多くなる。The number of inertial pulses varies depending on the amount of load, that is, the amount of laundry and the amount of water, and the smaller the load, the greater the number of pulses.

The total number of inertia pulses is 100.

If the total number is less than 50 (go to step), determine that the load is 4.5 to 6 kg, set the water level to high, and set the operation mode to 12 minutes of washing, 2 times of rinsing, and 5 minutes of dehydration. (Stesopka).
このようにして洗濯物の負荷量に応じて水位が決定され
、負荷判定のための規定の低水位からこの決定水位まで
給水された後、決定水位で洗い工程が開始する。In this way, the water level is determined according to the load amount of laundry, and after water is supplied from a predetermined low water level for load determination to this determined water level, the washing process starts at the determined water level.
ところが、洗い運転開始後は、使用者が任意に水位を変
更することも可能で、水位を変更設定すると洗い工程に
続くすすぎ工程では、この変更した水位ですすぎ運転が
行われる。However, after the washing operation starts, the user can arbitrarily change the water level, and when the water level is changed and set, the rinsing operation following the washing step is performed at the changed water level.

を傷めてしまうことがある。For example, if there is a lot of laundry and the load is large, even though the water level is automatically set to a high level, if you reset the water level to a lower level after starting washing, the rinsing process will only reach this low water level. No water is supplied, which means that the laundry is rinsed with less water, which can damage the fabric.

。In order to solve this inconvenience, it is possible to completely disable changing the water level after determining the load amount, but if this is done, it will also not be possible to change the water level to a high level where there is no risk of fabric damage, which will reduce usability. It ends up being bad.

濯機の水位制御方法を提供することにある。The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to provide an agitation type washing machine that allows the water level to be changed without fear of fabric damage after determining the load amount, prevents fabric damage, and is easy to use. The purpose of the present invention is to provide a water level control method.

ある。In order to achieve the above object, the present invention is provided with a rotation speed detection means for detecting the rotation speed due to the inertia of the stirring blade and the drive motor after the power supply to the drive motor is stopped, and washing is performed by alternately rotating the stirring blade in forward and reverse directions. In an agitating washing machine, after supplying water to a specified low water level, which is the water level for determining the load of the amount of laundry, the motor is rotated at a specified number of revolutions to determine the amount of load, and the water level is determined according to this amount of load. The gist of the rest is that it is not possible to change the water level to a level lower than the determined water level.

防止できる。[Operation] According to the present invention, the load amount of laundry is determined based on the output from the rotation speed detection means of the motor, and once the water level corresponding to this load amount is determined, the water level is thereafter lowered than the determined water level. Since it is not possible to change settings, when the load is large and the amount of laundry is large, rinsing is not performed with a small amount of water relative to the amount of laundry, and fabric damage caused by insufficient water can be prevented.
また、負荷量に対して多い水量への水位変更は可能であ
るから、水位変更が全面的に禁止されるわけではなく、
この範囲では使用者の希望にそうことができる。Also, since it is possible to change the water level to a higher amount of water than the load, changing the water level is not completely prohibited.
Within this range, the user can do whatever he or she desires.
以下、図面について本発明の実施例を詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

あるからここでの詳細な説明は省略する。FIG. 1 is a flowchart showing an embodiment of the water level control method for an agitation type washing machine according to the present invention, and the washing machine in which the method of the present invention is implemented is the same as that already explained with reference to FIGS. 2 to 4. Detailed explanation here will be omitted.
本発明においても、速度発電機（９）を有するモーター
回転検出回路（３０）を設けた撹拌式洗濯機で、第５図

を判定して負荷量に応じた水位を自動的に設定する。In the present invention as well, in an agitating washing machine equipped with a motor rotation detection circuit (30) having a speed generator (9), as already explained with reference to the flowchart of FIG.
After supplying water to a specified low water level for load determination, the motor (10) is rotated a specified number of times and the number of inertia pulses emitted during this period is integrated, and the load amount is determined based on the integrated value of the number of inertia pulses. Automatically sets the water level according to the water level.
本発明は、かかる負荷量の判定中、すなわち未だ水位が
決定されない間は（ステ・ノブヨ）、水位変更を不可と
して（ステップタ）使用者が任意に水位を決定して負荷
量に合わない水位が設定されることを禁止した。The present invention disables the water level from being changed (stepta) while the water level is being determined, that is, while the water level has not been determined yet, and allows the user to arbitrarily determine the water level so that the water level does not match the load amount. is prohibited from being set.
そして、水位が決定され、決定水位まで給水されて洗い
運転が開始した後は、決定水位が高水位でない限りは（
ステラプレ）、決定水位よりも一段上の水位への変更（
例えば決定水位が中水位の場合は中高水位への変更）は
可、低い水位への変更は不可としくステノプツ）、洗い
に続くすすぎ工程では洗い時よりも高い水位での運転が
行える。After the water level is determined, water is supplied to the determined water level, and washing operation starts, unless the determined water level is a high water level, (
Stellar Pre), changing the water level to one step higher than the determined water level (
For example, if the determined water level is a medium water level, it is possible to change the water level to a medium-high water level, but it is not possible to change it to a low water level.In the rinsing process following washing, operation can be performed at a higher water level than during washing.
この場合は、水位を変更しても、負荷量に対してこれよ
りも多い水量ですすぎが行われるから、水量不足による
布傷みのおそれはない。In this case, even if the water level is changed, rinsing is performed with a larger amount of water than the load, so there is no risk of damage to the fabric due to insufficient water.
これに対して、決定水位が高水位の場合は（ステラプレ
）、これよりも高い水位はないから水位変更を全面的に
不可とし負荷量判定により決定された設定水位で洗い、
すすぎを行う （ステソプソ）。On the other hand, if the determined water level is a high water level (Stella Pre), since there is no higher water level, it is completely impossible to change the water level, and the water level is washed at the set water level determined by the load amount judgment.
Perform rinsing (Stethopso).

定結果に基づいて決定され設定された水位よりも低い水
位が設定されることはない。When it is confirmed that the water level has been set as described above by the operation sound generated from the operation switch (29), etc., the water level change is completed, and in the present invention, the water level is determined based on the load amount determination result. A water level lower than the set water level will not be set.
以上述べたように本発明の撹拌式洗濯機の水位制御方法
は、負荷量に適した設定水位よりも低い水位への変更を
不可としたので洗濯物量に対して少ない水量で洗濯が行
われることがなく、水量不足による布傷み発生を防止で
きる。As described above, the water level control method of the agitation type washing machine of the present invention makes it impossible to change the water level to a level lower than the set water level suitable for the load, so that washing can be performed with a small amount of water relative to the amount of laundry. This prevents fabric damage due to insufficient water.
また、設定水位よりも高い水位への変更は可としたので
、布傷み発生のおそれのない範囲では使用者の希望にそ
うことができ使い勝手のよいものである。Furthermore, since it is possible to change the water level to a higher level than the set water level, the user can change the water level to a level higher than the set water level, as long as there is no risk of fabric damage, which is convenient for the user.

とを特徴とした撹拌式洗濯機の水位制御方法。A rotation speed detection means is provided to detect the rotation speed due to the inertia of the stirring blade and drive motor after the power supply to the drive motor is stopped.
In an agitator-type washing machine that washes laundry by alternating forward and reverse rotation of the agitating blades, water is supplied to a specified low water level, which is the load judgment water level for the amount of laundry, and then the motor is rotated at a specified number of revolutions to determine the load amount. A water level control method for an agitation type washing machine, characterized in that a water level is determined according to a load amount, and after the water level is determined, it is not possible to change the water level to a lower level than the determined water level.
