Description

Washing machine laundry detection method of washing machine

The present invention relates to a laundry extraction detection method of a washing machine. In particular, after performing a series of washing administrations, washing, rinsing, and dehydrating strokes, the laundry is terminated by detecting whether the laundry is taken out from the washing tank until a predetermined time elapses. Laundry laundry detection method of the washing machine to generate a laundry alarm when not taken out.

In general, when washing with a washing machine in our home, the user puts the laundry to be washed into the washing tank of the washing machine, and then supplies water, and when the water supply is completed, proceeds with the washing and rotating the pulsator forward and reverse, and when the washing is completed, the water is supplied again. After rinsing is performed while the pulsator is rotated forward and reverse, the rinsing is performed a predetermined number of times, ie, twice.

When the rinsing is finished as described above, the washing tank is rotated at a high speed to remove the washing water that has leaked into the rinsed laundry, and the washing process is completed by completing the dehydration process. When the washing is completed, the washing machine is completed. The laundry completion alarm sounds only for a predetermined time to inform the user of the laundry taking out.

If the dehydrated laundry is taken out immediately and left in the washing tank without drying, the laundry is compressed by the high-speed rotating centrifugal force when dehydrated and fixed in the washing tank as it is creased. If the user wants to wear the dried laundry, of course, it depends on the type of laundry, but there is a hassle that must be worn after almost all ironing, especially in the summer (rainy season) due to moisture or mold There is a fear that the microorganisms to breed, in the case of winter is frozen because the user has to trouble again to re-wash.

Nevertheless, if the user is not in the vicinity or inevitably goes out for a while when the alarm sounding notifies the end of the washing, when he returns home after returning home or when he is back in place, the user himself is away from the laundry. In some cases, the laundry may be left in the washing tank as it is, or it is forgotten to go out, which causes a problem of re-washing the washed laundry of the washing machine.

An object of the present invention is to detect the laundry withdrawal when the washing, rinsing, and dehydration of a series of washing administration is completed, and to warn if the laundry is not taken out until a predetermined time elapses, the laundry is finished washing In addition to preventing the washing machine from being left for a long time, it is intended to prevent re-washing, mold, or freezing due to long time.

In order to realize the above object, the present invention generates an alarm upon completion of the washing, rinsing, and dehydrating administration of a series of washing operations, and then detects whether the laundry is taken out, and determines that the laundry is taken out. If the predetermined time has not elapsed in a state where the predetermined time has not elapsed, the laundry is detected to be detected, and if the predetermined time has elapsed, the laundry extraction alarm is issued.
