<Explanation of symbols on main parts of the drawings>

S20: Drying administration D: Drying capacity of laundry

Dm: Maximum drying capacity

Drying administration method of the combined dry washing machine according to the present invention for solving the above problems is a first step of detecting the amount of laundry; A second step of determining whether the amount of laundry detected in the first step exceeds a maximum drying capacity; In the second step, if the amount of laundry exceeds the maximum drying capacity, the user is warned of an abnormal condition.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the operating method of the combined dry washing machine according to the present invention, after the laundry is loaded on the drum and the washing course is selected (S11), when the washing machine operation button is pressed (S12), the washing pattern is first set according to the selected washing course. After washing the water with detergent to the washing water level (S13), the drum is rotated by the driving force of the driving motor according to the set washing pattern to wash the laundry (S14), the drum after a predetermined washing time The washing water is drained to complete the washing of the laundry (S15).

Here, in the initial stage of washing, the washing water is initially supplied to the washing water level, and when the washing water is reduced to the water supply level due to the absorption of the laundry, the water is supplied again to the washing water level. Re-feeding several times until, the more the quantity of laundry, the greater the number of re-feeding can be detected the amount of laundry using the number of re-feeding of the wash.

Thereafter, the washing water to the drum to rinse water to rinse the laundry and then drained to perform a rinsing stroke (S16), after washing the laundry rinse the drum by rotating the drum to dehydrate the laundry by centrifugal force (S17).

At this time, since the weight of the drum and the amount of laundry loaded on the drum act as a load of the driving motor at the initial stage of the dehydration stroke, the driving motor is operated at an appropriate rotational speed, that is, the dehydration rotation speed for dewatering the laundry. It takes a predetermined time to rotate the drive, the larger the quantity of the laundry, the longer it takes for the drive motor to rotate the drum at the dehydration rotation speed, so that the drive motor starts the drum at the beginning of the dehydration stroke. You can also detect the volume of your laundry using the time to drive at the spin speed.

Next, after the dehydration stroke, hot air is blown to the drum to dry the laundry by evaporating the water vapor of the laundry (S20).

In this case, the combined dry washing machine according to the present invention has a maximum drying capacity that can load laundry on a drum for optimally drying the laundry, so that it is about 50% of the maximum washing capacity that can load laundry on a drum for cleaning. Drying administration is performed by the drying administration method of the combined drying washing machine so that the laundry can be dried in an appropriate state of drying capacity.

As shown in FIG. 4, the drying administration method of the combined washing machine according to the present invention first detects the dry capacity D of the laundry in the first step, that is, the amount of laundry loaded on the drum (S22).

At this time, the combined-use washing machine according to the present invention remembers the amount of laundry detected through the number of times of reloading the washing water during the washing stroke, and when the drying administration is started, the washing capacity of the laundry is determined by the amount of the washing laundry detected during the washing stroke. Recognize it as (D).

Meanwhile, in another embodiment, the combined-use washing machine according to another embodiment of the present invention remembers the quantity of laundry detected during the dehydration stroke, and when the drying administration is started, the dry capacity of the laundry detected in the dehydration stroke is determined. Recognize it as (D).

Next, the second step is to determine whether the dry capacity (D) of the laundry detected in the first step exceeds the maximum drying capacity (Dm) (S24), the third step is the dry capacity (D) of the laundry in the second step ) Is determined to exceed the maximum drying capacity (Dm) and the first step (S26, S27) to warn the user of an abnormal condition and the drying capacity (D) of the laundry in the second step is the maximum drying capacity (Dm) If it is determined that it is not over, the second step (S28) of proceeding to the drying administration.

In the first step of the third step, the drying capacity D of the laundry exceeds the maximum drying capacity Dm, so that the drying administration is stopped so that the drying administration does not continue, that is, the operation of the combined washing machine is stopped. Then (S26), the user operates an alarm or warning light separately provided in the combined washing machine so as to reduce the dry capacity (D) of the laundry to ventilate the user's surroundings (S27).

Of course, the alarm or warning light recognizes that the drying capacity of the laundry has exceeded the maximum drying capacity, and the user may perform a separate action such as pressing a button to stop the operation of the alarm or warning light or opening the door of the dry washing machine. It will continue to work until it is taken.

In the second step of the third step, since the drying capacity D of the laundry is an appropriate capacity for the laundry to be optimally dried, the laundry is dried by operating the drying apparatus to evaporate the water vapor by hot air (S28). .

That is, a blower for blowing air into and out of the drum, a heater for heating the air blown to the drum to a high temperature so that the laundry can be dried by hot air, and the air blown out of the drum is vaporized from the laundry. Due to the humidity of the water supply valve for supplying the cold water so that the condensation duct that guides the air out of the drum condensed water vapor in the air blown out of the drum.

The operating method and drying administration method of the combined dry washing machine according to the present invention configured as described above detects the dry capacity of the laundry during the drying stroke, so that the dry capacity of the laundry exceeds the maximum drying capacity, so that the laundry is not dried once. After stopping the drying stroke, an alarm or warning light is activated to inform the user that the dry capacity of the laundry has exceeded the maximum drying capacity. Therefore, the user can recognize that the dry capacity of the laundry has exceeded the maximum drying capacity and reduce the dry capacity of the laundry. Since the air is ventilated so that the drying capacity of the laundry exceeds the maximum drying capacity, there is an advantage that the drying performance is prevented from falling.
