3 is a flow chart of an embodiment of a method for controlling a single drying of a drying and washing machine according to the present invention.

First, when the cloth m is put into the drum 30 and the single drying is inputted through the control panel 7, the controller 70 does not perform the drying step immediately, m) is performed first. (S1) (S2)

Here, the dehydrating step is to prevent the moisture in the bag m from being dried before the drying step so that the bag m can be easily dried in the drying step. The controller 70 controls the motor 40 (For example, 1000 rpm) and the set time (for example, 5 minutes) to rotate the drum 30 at a high speed.

When the drum 30 rotates at a high speed, the drum m in the drum 30 adheres to the inner wall surface of the drum 30 due to centrifugal force, the water in the drum m is centrifugally dewatered, A considerable amount of water is removed and the subsequent drying becomes easy.

On the other hand, the dehydrated water in the cloth m flows out through the through hole 32 of the drum 30 and between the drum 30 and the tub 10, flows down to the inner lower part of the tub 10, At this time, when the drain pump 16 is driven, the water is drained through the drainage device 17.

The control unit 70 ends the dehydration step when the set time (for example, five minutes) elapses after driving the motor 40 at the set RPM (for example, 1000 rpm). S4)

Then, the control unit 70 performs a drying step of drying the cloth m.

The controller 70 drives the motor 40 to a smaller diameter than the dewatering step so that the foam m can flow in the drum 30 during the drying step and the motor 40 Stop driving.

The control unit 70 turns on the heater 52 and drives the fan motor 56 for rotating the blowing fan 54. The control unit 70 also turns on the cooling water valve 62 to perform hot air drying of the pod.

The air A in the drum 30 flows into the drum 30 while being in contact with the laundry m and is then changed into a humid atmosphere through the air hole 32. Then, The moisture in the air is condensed in the condensed water as the heat is exchanged with the condensed water supplied to the condensing duct 38 while passing through the condensing duct 38 and the humidity is lowered. (56).

The blown air is heated by the heater 52 to be converted into hot air and then introduced into the drum 30 through the tub 10 and then repeatedly circulated / Continuously dry.

Here, since the hot air drying is a state in which the water of the cloth is sufficiently removed in the dehydrating step, the cloth is dried efficiently from the beginning.

On the other hand, the drying degree sensors 66 and 67 detect the degree of drying during the hot air drying as described above and output a signal to the control unit 70, If the sensed degree of drying does not reach the predetermined drying degree and the hot air drying time does not reach the set drying time, the hot air drying is continued.

On the other hand, when the sensed drying degree reaches the set drying degree or the hot air drying time reaches the set drying time, the controller 70 ends the hot air drying (S6) (S7) (S8)

Hereinafter, the detection of the degree of drying and the determination of the degree of drying will be described in more detail.

)를 설정 온도차(예를 들면, 30℃)와 비교한다.The condensing duct temperature sensor 66 and the tub temperature sensor 67 output a signal according to the sensed temperature value to the controller 70. The controller 70 senses the temperature value sensed by the condensate duct temperature sensor 66 (T1) detected by the tub temperature sensor 67 and the temperature value T2 detected by the tub temperature sensor 67

Is compared with a set temperature difference (for example, 30 DEG C).

)가 설정 온도차 이상이면 건조가 충분하게 이루어진 것으로 판단하고, 상기 감지된 온도값(T1,T2)들의 차(

)가 설정 온도차 미만이면 건조가 충분하게 이루어지지 못한 것으로 판단한다.The control unit 70 calculates a difference between the sensed temperature values T1 and T2

) Is greater than or equal to the preset temperature difference, it is determined that the drying has been performed sufficiently, and the difference of the sensed temperature values (T1, T2)

) Is less than the set temperature difference, it is judged that drying is not sufficiently performed.

On the other hand, after the hot air drying is completed, the controller 70 turns off the heater 52 and turns off the cooling water valve 62 to cool and dry the cloth m (S9)

When the heater 52 and the cooling water valve 62 are turned off and the blowing fan 54 is rotated, air in the drum 30 is blown into the through hole 32 of the drum 30 and the tub 10 Through the condensing duct 38 and the drying duct 56 in this order and flows into the drum 30 and the temperature of the capsule m is gradually increased by repeating the above- Lower.

 The control unit 70 stops driving the fan motor 56 to stop the blowing fan 54 when the cold air drying is performed for the set time, (S11)

4 is a flow chart of another embodiment of the method for controlling the drying of the washing machine combined with drying according to the present invention.

In the single drying control method of the washing machine combined with drying according to the present embodiment, the dehydrating step is carried out with dehydrating agent and dehydrating time determined according to the amount of dehydrating agent.

That is, when the laundry m is poured into the drum 30 and single drying is input through the control panel 7, the drying and washing machine senses the laundry amount first (S1) (S2 ').

Here, it is also possible to sense the amount of the drum 30 in accordance with the measured time by measuring the time taken for the drum 30 to rotate by driving the motor 40 so that the drum 30 rotates once.

When the number of rotations of the motor 40 reaches the reference number of revolutions, the constant speed is maintained for a predetermined time, and then the motor 40 (Duty) of the pulse width modulation (PWM) from the starting time to the constant speed holding time and the rotation angle in accordance with the rotation of the motor 40 in the available rotation of the motor 40 are measured, ) Value multiplied by a proportional constant and a value obtained by multiplying the rotation angle by a proportional constant to determine the final amount. In addition to the methods described above, it is possible to detect the amount of the discharged material by various methods.

The control unit 70 determines the dehydrating time and dehydration time according to the sensed amount of water and drives the motor 40 to centrifugally dehydrate the water.

Since the other components and actions other than the above-mentioned detection of the amount of water and the determination of the dehydration time and the dehydration time are the same as those of the embodiment of the present invention, the same reference numerals are used and a detailed description thereof will be omitted.

It should be noted that the present invention is not limited to the above embodiments, and it is also possible to determine the time of cold air drying and the like according to the amount of the laundry, and to perform the cold air drying accordingly, Of course.

In the single drying control method of the drying and washing machine of the present invention having the above-described structure, in the case where a command for single drying is inputted, dehydration of the cloth is performed before the cloth is dried to sufficiently remove the moisture of the cloth, Since the drying is performed, there is an advantage that drying performance at the time of single drying can be improved and drying failure can be prevented.

Further, in the single drying control method of the washing machine of the present invention, dehydration is detected and the dehydration time and the dehydration time are determined according to the detected dehydration amount and dehydration is performed according to the dehydration amount and dehydration time, , And the drying performance is further improved.
