    How to dry laundry in a drum washing machine
    The present invention relates to a washing machine, and more particularly, to a laundry drying method of a drum washing machine.
    Generally, a washing machine is a machine for washing laundry by performing washing, rinsing, and dehydrating strokes according to a predetermined algorithm. The washing machine is classified into a pulsator type, a stirring type, a drum type, and the like according to a washing method.
    At this time, drum washing machine is widely used because it has the lowest laundry damage rate and lowest quantity of use compared to other types of washing machines, and meets the needs of users who require multifunction and full automation, and keeps pace with the technology development that is becoming home automation. Various additional functions are added for this purpose. As one of the additional functions, a drying stroke is widely adopted in addition to the basic washing stroke, that is, washing, rinsing, and dehydration, and a drying only course for drying only wet clothes and the like without performing the washing stroke is part of the drying stroke. It may also be employed as.
    Hereinafter, the laundry drying method of the drum washing machine according to the prior art will be described.
    1 is a flowchart illustrating a laundry drying method of a drum washing machine according to the related art.
    As shown in Figure 1, the laundry drying method of the drum washing machine according to the prior art first, the user puts the laundry in the drum of the drum washing machine, and then the washing instruction including the drying administration, the instruction for performing the drying course only or the drying administration Enter the command. Subsequently, the controller of the drum washing machine determines whether a washing instruction is input (S11), and when a washing instruction is input, determines whether a drying administration is selected during the washing instruction (S12). If the result of the determination (S12) is a washing instruction in which the drying administration is not selected, the amount of washing cloth is sensed, the water supply or drainage is repeated appropriately, and washing, rinsing or dehydration is performed to correspond to the input washing instruction (S13). ).
    On the other hand, the determination result (S12), if the drying administration is selected to determine whether the drying only course is selected (S14), if the drying only course is selected to perform the drying administration (S16), if the drying only course is entered above Washing, rinsing or dehydration is performed to correspond to the washing instruction (S15) and then the drying administration is performed (S16).
    At this time, the drying administration circulates the hot air using the heater inside the drum washing machine to pass through the drum to dry the laundry cloth.
    And look at the detailed operation for determining the drying degree of the laundry cloth as follows.
    First, a certain amount of water is supplied to the laundry cloth in the drum. Subsequently, the hot air using the heater is circulated along a predetermined path to dry the laundry cloth. The temperature is lowered by the moisture supplied to the laundry cloth, and the temperature of the returned hot wind and the temperature inside the drum are measured to determine whether the temperature difference between the temperature inside the drum and the returned hot wind is less than or equal to a predetermined value 'ΔT'. (S17), when the temperature difference is 'ΔT' or less, it is determined that drying is completed (S18), and completes the drying process.
    At this time, 'ΔT' is a value set based on the laundry cloth dried under a predetermined reference value.
    On the other hand, the determination result (S17), if the temperature difference is 'ΔT' or more, it is determined that drying is not completed, repeats the drying operation, and repeats the determination step (S17) to complete the drying operation if the conditions are satisfied.
    In the laundry drying method of the drum washing machine according to the prior art, when a laundry having a moisture content of a certain amount or more is dried in a drying-only course that does not perform a dehydration stroke, it takes longer to perform drying than a laundry that has been dehydrated. As the power consumption increases, the amount of water used for measuring temperature used to determine the drying is also increased.
    Accordingly, an object of the present invention is to provide a laundry drying method of a drum washing machine, which can minimize the time performed in a drying process.
    1 is a flowchart illustrating a laundry drying method of a drum washing machine according to the related art.
    2 is a flow chart illustrating a laundry drying method of a drum washing machine according to the present invention.
    According to the present invention, if the washing instruction is input, determining whether the drying-only course is selected, measuring the water content of the laundry according to the result of determining whether the drying-only course is selected, and the water content is fixed according to the water content measurement value. Characterized in that it comprises a step of performing a drying stroke by adjusting to a level.
    Hereinafter, a laundry drying method of a drum washing machine according to the present invention will be described with reference to the accompanying drawings.
    2 is a flowchart illustrating a laundry drying method of a drum washing machine according to the present invention.
    2, the laundry drying method of the drum washing machine according to the present invention, first, the user puts the laundry in the drum of the drum washing machine, and then washing instructions, including the drying administration, the instruction for performing a dedicated drying course or the drying administration Enter. Subsequently, the controller of the drum washing machine determines whether a washing instruction is input (S21), and when a washing instruction is input, determines whether the washing instruction includes a drying administration (S22). If the result of the determination (S22), in the case of a washing instruction that does not include a drying administration, detects the quantity of the washing cloth, repeats water supply or drainage as appropriate, and performs washing, rinsing, or dehydration to correspond to the input washing instruction (S23). ).
    On the other hand, in the determination result (S22), if the drying administration is selected it is determined whether the drying-only course is selected (S24).
    In this case, the drying-only course performs only drying without performing a dehydration stroke, so that the moisture content of the current laundry is measured and appropriated in preparation for the case where the water content of the current laundry is higher than that of the laundry which has undergone the dehydration stroke. Perform a series of actions to adjust to level.
    Subsequently, when the drying-only course is selected, the above series of operations are performed. That is, after performing a low speed dehydration for a predetermined time (S25), the water level (W S ) of the deceased in the washing tank due to dehydration is measured and compared with the dryable water level (W D ) (S26), the comparison result (S26) If W S is less than or equal to W D , a predetermined amount of water is supplied to the laundry cloth in the drum, and hot air is circulated along a predetermined path to pass through the drum (S29).
    On the other hand, if W S is not less than W D to perform high-speed dehydration to reduce the water content of the laundry (S27), when W S is less than W D is carried out a drying administration (S29).
    And if the determination result (S24), the drying only course is not performed washing, rinsing or dehydration to correspond to the input washing instruction (S28), and performs the drying administration (S29).
    Subsequently, the temperature of the hot air returned through the drum and the temperature of the drum are measured to determine whether the temperature difference between the temperature inside the drum and the hot air returned is less than or equal to a predetermined value 'T' (S30). Is less than 'ΔT' is determined to be complete drying (S31), and completes the drying administration.
    On the other hand, if the temperature difference is less than 'ΔT' or less, it is determined that drying is not completed, repeats the drying process, and repeats the determination step to complete the drying process if the conditions are satisfied.
    In the laundry drying method of the drum washing machine according to the present invention, when the water content of the laundry is more than a predetermined level, drying is performed after adjusting to an appropriate level, thereby reducing drying time, power consumption, and washing water consumption according to the drying performance of the drum washing machine. There is an effect that can improve the efficiency.
