After the water is supplied, washing, rinsing, and dehydration strokes are performed according to the set washing pattern.

Then, when the drying course is selected, when the dehydration stroke is completed, hot air is blown into the drum 10, and the laundry is dried while steam of the laundry evaporates.

Specifically, the drying process of the laundry, during the drying stroke, the air of the drying duct 22 is heated by the heater 24 and then flows into the drum 10 to evaporate water vapor of the laundry, and the drum ( 10, the humid air is guided to the condensation duct 26, the water vapor in the air is dried by condensation by cold water, and then heated again by the heater 24 in the drying duct 22 and then inside the drum 10 Circulate The cold water and the condensed water condensed in the condensation duct 26 are drained by a drainage device.

However, the conventional combined-use washing machine according to the prior art can dry laundry close to 100% dryness, but the energy consumption is large, which makes it difficult for the consumer to always select a drying course and the laundry is dried by hot air in a confined space for a long time. There is a problem that it smells squishy and the fabric is damaged.

The present invention has been made in order to solve the above problems of the prior art, by laundering the laundry step by step dehydration to 55 to 70% level of dryness so that it can be dried in a short time by drying the laundry energy consumption and drying It is an object of the present invention to reduce the time at the same time, to provide a washing method of a dry combined washing machine that can prevent the smell and damage of laundry due to hot air.

Washing method of the combined dry washing machine according to the present invention for solving the above problems is a set administration of any one of the standard course, the full drying course, the semi-dry course of the washing course is set, the washing pattern is set; A washing stroke in which washing water is removed as the washing tank is rotated after washing water is supplied with detergent according to the washing pattern set in the setting stroke; A rinsing stroke in which the washing water is rinsed by washing the laundry after the washing stroke is completed; When the rinsing stroke is completed, when the standard course is set in the set stroke, the washing tank is rotated at high speed to proceed to the dehydration mode in which the laundry is dehydrated by centrifugal force, and when the full drying course is selected in the set stroke, After the dehydration stroke, supply the hot air to the washing tank and proceed to the drying mode in which the laundry is completely dried. When the semi-dry course is selected in the setting stroke, the laundry is dried stepwise by centrifugal force and hot air. It is composed of dehydration / drying stroke which proceeds to semi-drying mode which is dried at% level as well as inflated.

And, the semi-drying mode is a simple dehydration step of washing the laundry is rotated at a constant speed when the eccentric amount of the laundry deposited in the washing tank within the allowable range, the laundry is first dehydrated by centrifugal force; After the simple dewatering step, the initial bathing step of tangling the laundry while the washing tank is stirred and rotated; After the initial inflating step, the washing tank is rotated at a higher speed than the simple dewatering step, so that the laundry is dewatered secondary by centrifugal force; After the present dewatering step, the washing tank is stirred and rotated, the finishing bubble expansion step of tangling the laundry; The drying apparatus for supplying the hot air to the washing tank during the last inflating step is operated so that the laundry is finished drying by hot air.

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

In the washing method of the combined-use washing machine according to the present invention, when the user selects the washing course as shown in FIG. 2, the washing pattern is set according to the set washing course and the quantity (D10), and the washing water is determined according to the set washing pattern. After the water is supplied to the washing tank and the washing tank is rotated at the washing speed, the laundry is removed by washing due to the emulsification of the detergent and friction with the water stream and the washing tank (D20), and when the washing administration (D20) is completed, the washing washing again in the washing tank. The water is supplied and the washing tank is rotated at the rinsing speed so that the laundry is rinsed (D30).

Thereafter, when the user selects the standard course, the washing tank is rotated at about 2000 rpm at a high speed so that the laundry is dehydrated to a level of about 50% by centrifugal force, and a dehydration mode (D40) is performed. When the full drying course is selected, After the dehydration mode (D52) according to the standard course, the hot air is supplied to the washing tank for a long time by the drying apparatus and the drying mode (D54) in which the laundry is dried to a level close to 100% dryness by evaporating the water of the laundry by the hot air. It proceeds (D50).

In addition, when the user selects a semi-dry course, the laundry is gradually dried to a level of 55 to 70% by centrifugal force and hot air according to the semi-dry method as described below, and is overlaid (D60). .

In the semi-drying method of the combined-use washing machine according to the first embodiment of the present invention, as shown in FIGS. 3 and 4, when the amount of eccentricity of the laundry deposited on the drum is within an allowable range, the laundry is centrifugal while the drum rotates at a constant speed. The first dehydration step (S10, S10 ') and the first dehydration step (S10, S10') by the completion of the simple dehydration step (S10, S10 '), the drum is stirred and rotated while initial folds of the laundry tangling (S20, S20') and When the initial inflating step (S20, S20) is completed, while the drum is rotated at a higher speed than the simple dehydration step (S10, S10 '), the laundry is dewatered by centrifugal force secondary dehydration step (S30) and the bone When the dehydration step (S30) is completed, the drum is stirred and rotated to finish the tangles of the laundry is loosened (S40), in particular during the last inflating step (S40) is supplied with hot air to the washing tank by the drying apparatus laundry Bites Evaporated by hot air being further it includes a hot air step (S50) that the laundry is finished drying.

Specifically, the simple dehydration step (S10, S10 ') is a drum vibrating violently when the drum is rotated by the motor, if the amount of eccentricity of the laundry is excessively, first, the load of the laundry through a change in the load on the motor In order to detect the amount of eccentricity, an eccentric detection process (S12) is performed in which the motor is driven for about 1 minute at a critical speed, that is, the minimum speed at which the laundry can be stuck to the wall of the drum without being dropped by gravity during rotation of the drum. do.

Then, if the amount of eccentricity of the laundry in the eccentric detection process (S12) is within the allowable range, in the present dehydration step (S30), the heavy the laundry is compressed to the wall of the drum by the centrifugal force and caught in the hand of the drum, Before the dehydration step (S30), the primary dehydration process (S14) is performed to dehydrate the laundry by centrifugal force so that the water content of the laundry is less than a predetermined level.

Of course, in the primary dehydration process (S14), the laundry is not dropped by gravity but attached to the wall of the drum by the centrifugal force, but the speed of the motor is set so that the laundry is not caught by the drum by the centrifugal force, Since the water content of the laundry is high, the motor speed is set relatively low, about 600 to 900 rpm.

However, the lower the speed of the motor, the smaller the centrifugal force is, so that it is difficult to sufficiently dehydrate the laundry before the present dehydration step (S30), so that the water content of the laundry gradually decreases during the first dehydration process (S14). Is set to increase gradually so that the laundry is dewatered in stages.

In addition, since the laundry is further tangled by the rotation of the washing tank in the primary dehydration process (S14) or the laundry dehydration speed varies according to the type of laundry, the amount of eccentricity of the laundry may vary, so the simple dehydration step (S10, S10 ') is performed by the motor. A plurality of times are alternately performed with the initial inflating step (S20, S20 ') on the basis of the time point at which the speed is increased.

That is, the simple dehydration step (S10, S10 ') is the first simple dewatering step (S10) and the primary dewatering process (S10) in which the motor is driven for about 30 seconds at a speed of about 600rpm in the primary dewatering process (S14) In step S14), the motor is composed of a second simple dehydration step (S10 ') driven for about 3 minutes at a speed of about 900 rpm, and the initial inflating steps (S20, S20') are also performed first and second times. Inflated step (S20, S20 ') is made.

Next, the initial inflating step (S20, S20 ') is the motor is turned on / off according to the set duty (Duty) and set to be driven alternately in the forward / reverse direction so that the drum is stirred and rotated by washing the laundry from the wall of the drum Drop it and apply it evenly.

In the initial inflating step (S20, S20 '), the control speed of the motor is about 50rpm, the duty value of the on / off time ratio of the motor in seconds is 4/10, the initial inflating time is 1 minute 30 seconds to 2 30 minutes.

Next, the dehydration step (S30) is an eccentric detection process (S32) for detecting the eccentricity of the laundry in the same manner as the eccentric detection process (S12) of the simple dehydration step (S10, S10 '), and the eccentric amount of the laundry Within this time, the laundry is not dropped by gravity but adheres to the drum by centrifugal force, but the motor is driven for about 13 minutes at about 1200rpm so that the laundry is not dehydrated by the centrifugal force. Secondary dehydration process (S34) to be dried, and after the secondary dehydration process (S34) consists of a process (S36) that the laundry is dewatered extended by the power of the motor.

Next, the finishing foaming step (S40) by dropping the laundry from the wall of the drum and releasing the tangling of the laundry so that the user can easily take out the laundry one by one to hung on the drying rack (S20, S20 ') It takes about 3 minutes in the same way.

Finally, the hot air step (S50) is the power is applied to the drying heater installed in the drying duct at the same time as the main dehydration step (S30) is completed, the air of the drying duct is heated, the laundry is stored by the blower installed in the drying duct As the air is blown into the washing tank, the water of the laundry is evaporated by hot air, and the wrinkles of the laundry are unfolded.

On the other hand, the semi-drying method of the combined dry washing machine according to the second embodiment of the present invention operates the drying apparatus during the simple dehydration step (S10, S10 ') as shown in Figure 5 and 6 to dry the laundry by hot air Hot air step (S60) to be carried out together to be carried out.

At this time, the hot air step (S60) is preferably carried out at the same time as the primary dehydration process (S14) after the eccentric detection process (S12) for detecting the eccentricity of the laundry in the simple dehydration step (S10, S10 ').

5 and 6 are the same as those of FIGS. 3 and 4 except for the above, and further description thereof will be omitted.

In addition, in the semi-drying method of the combined dry washing machine according to the third embodiment of the present invention, the laundry is dried by hot air by operating a drying apparatus during the simple dehydration step (S10, S10 ') as shown in FIGS. 7 and 8. The hot air step (S70) to be carried out together, and the hot air step may not be carried out at the time of finishing the inflating step (S40).

At this time, the hot air step (S70) is preferably carried out at the same time as the primary dehydration process (S14) after the eccentric detection process (S12) for detecting the amount of eccentricity of the laundry in the simple dehydration step (S10, s10 ').

7 and 8 are the same as those of FIGS. 3 and 4 except for the above, and further description thereof will be omitted.

The semi-drying method of the above washing machine is slightly less dried due to the dehydration of the laundry step by step, that is, the drying degree is about 55 to 70%, and the laundry is frequently dehydrated and bubbled to entangle the laundry. Because it is released, the laundry can be dried in a short time in the outside or in the room, and the clothes can be ironed immediately without being naturally dried, and the washing time is not severe and the ironing time can be reduced.

In particular, the semi-drying method according to the present invention is not only improves the dryness of the laundry because the hot air step (S50) is carried out by the hot air to evaporate the laundry water, the wrinkles of the laundry is stretched as if ironed, and the laundry is withdrawn The warmth remains in the laundry when it is whisked and not only makes the user feel dry, but the dryness of the laundry is further condensed and dried due to the difference between the laundry and the outside temperature, and the dryness of the laundry is further improved. Since it is only supplied for hours, the hot air does not damage the laundry or give it a scent.

In addition, according to the present invention, a washing course may be more variously selected by the consumer according to washing conditions such as weather, time, and economics including energy consumption.

In the washing method of the combined dry washing machine according to the present invention configured as described above, after the washing and rinsing stroke, a general dehydration mode in which the laundry is dehydrated by centrifugal force is performed according to the selection of the washing course, or the laundry is completely dried by hot air. Mode or laundry is dehydrated stepwise by centrifugal force and hot air, and semi-dry mode, which is alternately swollen with dehydration, allows consumers to choose the washing course according to the washing conditions such as weather, time and energy consumption. There is an advantage.

In addition, in the semi-dry mode according to the present invention, if the amount of eccentricity of the laundry deposited in the washing tank is within the allowable range, the washing tank is rotated at a constant speed so that the laundry is dehydrated primarily by centrifugal force, and the washing tank after the simple dewatering step is Initial defoaming step of tangling the laundry while rotating by stirring, and after the initial defoaming step, the washing tank is rotated at a higher speed than the simple dehydration step so that the laundry is dehydrated by centrifugal force, and the main dehydration. After the step, the finishing tubing step of releasing the tangles of the laundry while the washing tank is stirred and rotated, and a drying device for supplying hot air to the washing tank during the last inflating step or the simple dehydration step is operated to finish drying the laundry by hot air As it consists of stages, laundry is dried by 55 ~ 70% level by staged dehydration and hot air drying. Drying in a furnace, that is, in a slightly less dry condition, not only allows the laundry to dry naturally in a short time, but also can be ironed and put on immediately, and the tangling and wrinkling of the laundry can be achieved by folds and hot air drying. have.
