Abstract

PURPOSE:To enable setting of washing set time without preliminary extension for water level detection by correcting either of a set water level or a value from a feed quantity detecting means to make the set water level detectable. CONSTITUTION:A washing machine having a water level setting means 28 for setting the water level of the washing machine and a feed quantity detecting means 18 and automatically feeding water up to a set water level is provided. A desired set water level can be detected without operation stop during washing operation by correcting either of the set water level or the value from the feed quantity detecting means. Hence, even if the water in a tank is moving when the water level is judged during washing operation, the set water level can be precisely detected, so that interruption of washing operation for water level detection is not required, and the washing time can be substantially shortened.

By the way, in the washing step, the control circuit (28)
The water supply valve (31) opens and automatically starts water supply based on the output from the water level sensor (18), and stops the water supply when it is determined that the set water level has been reached based on the output from the water level sensor (18).

As a result, as shown in the flowchart of FIG.
If the set water level is low, the oscillation frequency f output from the water level sensor (18) during water supply is r.
If it becomes smaller than l, it is assumed that the set water level has been reached and the water supply ends (step). Similarly, when the set water level is "medium" (step force), the water supply will be stopped if the oscillation frequency f becomes smaller than fz (step force), and if the set water level is "
Similarly, in the case of “high” (step force), the oscillation frequency r is f3
If it becomes smaller than (Stepum), water supply will be stopped.

This is because even if the set water level is reached before the washing operation starts, the clothes will absorb water afterwards and the washing/dehydration tank (4
), and when the motor (10) is rotating and the stirring blade (3) is rotating, a water flow is generated in the washing/spinner tank (4), making it impossible to measure the water level accurately. (
10) is stopped to make the water stand still.

As a result of the water level judgment, if the set water level has not been reached (step CH), water is supplied again (STEP CH), and when the set water level is reached (STEP CH), the water supply is stopped (STEP CO) and the motor operation is controlled. (Restart Step 5) and continue washing until the set time is over.

After starting the washing operation, when re-judging whether the water level has reached the set water level, as mentioned above, it is necessary to temporarily stop the motor drive and return the water in the tank to a still state. This stationary state must continue until the water supply ends.

Therefore, the stirring blades do not rotate and washing is not performed while the water level is being re-determined, but this time is included in the washing operation time set at the start of operation, so the washing time is actually reduced by this time. As a result, a sufficient cleaning effect cannot be obtained.

As described above, the washing machine operation control method of the present invention can correctly detect the set water level even if the water in the tank is moving when determining the water level during the washing operation. This eliminates the need to temporarily stop the washing process, substantially shortening the washing time and preventing the washing effect from deteriorating. Furthermore, since there is no need to extend the wash setting time in advance to detect the water level, there is no need to waste time.
