The present invention relates to a semi-drying method of a washing machine, and more particularly, to a semi-drying method of a washing machine that dehydrates laundry in stages by centrifugal force and warm air.

The drum washing machine according to the prior art has a cabinet (2) having a door (1) in the front as shown in Figure 1, and a tub (6) supported and fixed by a damper (4) inside the cabinet (2) And a drum 8 installed inside the tub 6 so as to be rotatable in a horizontal direction in a axial direction, in which laundry is deposited and a hand 8a is formed, and a rear side of the tub 6 is provided with the drum ( 8) connected to the rotary shaft 9, the motor 10 for rotating the drum 8, the water supply device 12 for supplying the wash water to the tub 6 and the drum 8, and the tub ( 6) and a drainage device 14 for draining the wash water supplied to the drum 8.

In addition, a controller for controlling the operation of the detergent box 16 and the washing machine in which the detergent is stored so that detergent is supplied to the tub 6 and the drum 8 together with the washing water at the time of washing the cabinet (2). 18 is installed, a heater 20 is installed at the lower side of the tub 6 to heat the wash water supplied during the washing stroke so that laundry can be boiled. The lift 22 is installed to lift the laundry to a certain height during the rotation of 8).

Looking at the operation of the washing machine configured as described above are as follows.

When laundry is loaded on the drum 8 and the washing pattern is input through the controller 18, detergent is first supplied to the tub 6 and the drum 8 together with the washing water, and then the drum 8 is driven by a motor. When the driving force of (10) is transmitted and rotated, the chemical reaction of the detergent and the friction force between the laundry and the water, and the laundry are lifted up to a certain height by the lifter 22, and then the friction force is rubbed with the drum 8 while falling by gravity. The laundry is washed and the contaminated washing water is drained after a certain time.

Next, only the wash water is supplied to the tub 6 and the drum 8 again, the laundry is rinsed as the drum 8 is rotated, and contaminated wash water is drained, and the drum 8 is then discharged for 3 to 5 minutes. The laundry is dewatered by centrifugal force while rotating at high speed at 1000 ~ 3000rpm.

However, in the prior art, since the drum 8 is rotated at high speed so that the laundry is dehydrated by centrifugal force during dehydration, the laundry is entangled with each other after dehydration and the laundry is inserted into the hand 8a of the drum 8. Since the process of taking out the laundry and untangling the laundry and hanging it on the drying rack is not only difficult, but also requires drying the laundry outside for a long time, weather and time constraints are required, and the wrinkles of the laundry are severe, requiring post-treatment such as ironing after drying. There is a problem.

On the other hand, nowadays, as shown in FIG. 2, a drying apparatus 30 for artificially drying laundry in a short time by using hot air in a washing machine may be installed. In this case, the hot air in the tub 6 and the drum 8 may be installed. Since the duct 32 and fan 34 for supplying the heater and the heater 36 for heating the air are additionally installed, not only the size of the washing machine is increased but also the price is high, and the drying time due to the hot air takes about 2 to 3 hours. There is a lot of energy consumption, the laundry is dried by hot air in a closed space for a long time there is a problem that the laundry smells squeeze and the cloth is damaged.

The present invention has been made to solve the above problems of the prior art, it is an object of the present invention to provide a semi-drying method of a washing machine to minimize the wrinkles of laundry after dehydration and to increase the dryness of the laundry.

The semi-drying method of the washing machine according to the present invention for solving the above problems is a simple dehydration step in which the laundry is first dehydrated by centrifugal force while the washing tank is rotated at a constant speed when the amount of eccentricity of the laundry accumulated in the washing tank is within an allowable range; After the simple dehydration step, the washing tub is stirred and rotated, the initial folding step of tangling the laundry, and after the initial foaming step, the washing tank is rotated at a higher speed than the simple dewatering step, and the wash water supplied so that the heater is locked. This dehydration step is heated by the heater and the laundry is dewatered secondary by centrifugal force and warm air, and after the main dewatering step, the washing tank is stirred and rotated to finish tangling of the laundry is loosened.

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

Semi-dry course washing method of the washing machine according to the present invention, when the laundry is loaded on the drum rotatably installed in the tub as shown in Figure 3 and the washing course is selected (A), washing water to the tub and drum with detergent After the water is supplied, the drum is rotated to wash the laundry due to the chemical reaction of the detergent and the friction between the water tank and the washing tank, and when the washing stroke (B) is completed, clean laundry water is supplied again to wash the laundry. When the rinsing stroke (C) to be rinsed and the rinsing stroke (C) is completed, the laundry is dehydrated step by step according to the semi-dry course algorithm and the laundry is entangled so that the laundry is 55-70%, ie, slightly without wrinkling. It consists of a semi-dry stroke (D) which is dried in a less curled state.

In the above, the heater is heated under the electric resistance while the power is supplied to the lower side of the tub is installed to heat the wash water can wash the laundry boiled in the laundry administration (B).

The semi-drying stroke (D) is a simple dehydration in which the laundry is dehydrated by centrifugal force while the drum is rotated at a constant speed when the eccentricity of the laundry deposited on the drum is within an allowable range, as shown in FIGS. 4 and 5. When the step (S10, S10 '), and the simple dehydration step (S10, S10') is completed, the initial folding step (S20, s20 ') and the initial folding step that the drum is stirred and rotated while the drum is stirred and rotated When the (S20, S20 ') is completed, the drum is rotated at a higher speed than the simple dehydration step (S10, s10'), and the washing water supplied with a small amount of water so that the heater is locked is heated by the heater so that the laundry is centrifugal and hot air. The dehydration step (S30) and the dehydration step (S30) by the secondary dehydration step (S30) is completed when the drum is stirred and rotated and consists of a finishing foaming step (S40) to loosen the laundry tangling.

Specifically, in the simple dehydration step (S10, S10 '), when the drum is rotated by the motor, if the amount of eccentric laundry is excessively vibrated, the drum vibrates violently. An eccentric detection process in which the motor is driven at a critical speed, that is, a minimum speed of 350 rpm, that can be attached to the wall of the drum without being dropped by gravity when the drum is rotated to detect an eccentric amount of laundry through the drum. (S12) is performed.

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 centrifugal force, so as to be caught in the manual work of the drum, Prior to 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 surface of the drum by centrifugal force, but the speed of the motor so that the laundry is not caught in the hand of the drum of the washing tank 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 is different depending on the type of laundry, the amount of eccentricity of the laundry may vary, so the simple dehydration step (S10, S10 ') is performed. On the basis of the timing at which the speed of the motor increases, a plurality of times are alternately performed with the initial inflating steps S20 and S20 '.

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 to the laundry of the drum Evenly remove it from the wall.

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), first, an eccentric detection process (S32) for detecting an eccentric amount of laundry in the same manner as the eccentric detection process (S12) of the simple dehydration step (S10, S10 ').

The motor is then driven for about 13 minutes at about 1200 rpm so that the laundry does not fall by gravity and adheres to the drum by centrifugal force, but does not get caught in the hand of the drum, and at the same time the heater is constant after a small amount of wash water is supplied. Secondary dehydration process (S34) that is powered for a time is performed.

At this time, the washing water is supplied with a certain amount as the drum rotates.

That is, when the heater is not completely immersed in the wash water, the area exposed outside the wash water deteriorates and a safety accident occurs. Thus, the wash water is at least the heater so that the wash water does not evaporate and the water level of the wash water is lowered during the operation of the heater. Water so that it is completely submerged.

When the wash water is supplied too much, the wash water flows into the drum, and the laundry accumulated in the drum is wetted by the wash water so that the wash water is supplied to an appropriate level so that the wash water does not flow into the drum.

The heater is operated for 4 minutes to 12 minutes so that the washing water is heated to 35 ° C. to 75 ° C. immediately after water supply of the washing water is completed.

Of course, the washing water is supplied in the dehydration step (S30), the driving of the drain pump for draining the washing water from the tub and the drum is stopped so that the washing water is not drained when the heater is in operation, after the operation of the heater is completed The drain pump is driven at a time interval t of about 30 seconds.

On the other hand, when water is supplied to the washing water in the dehydration step (S30), even if the water supply amount of the wash water is set in advance, the water supply amount is generated according to the washing water supply speed and temperature, so it is not possible to always supply the washing water to the proper water level. In addition, since there are many variables affecting the evaporation rate of the wash water when the heater is operated, there is a risk that the water level of the wash water may be lowered below the minimum level at which the heater is immersed even though the operating time of the heater remains.

Therefore, in the present dehydration step (S30), the water supply device for supplying the wash water so that the wash water is supplied to the proper level according to the detection result of the water level sensor for detecting the water level of the washing water is controlled, and the washing during operation of the heater The heater is controlled to stop the operation of the heater when the water level reaches the minimum level.

In this dehydration step (S30), since the drum () is rotated at a high speed by a motor, the laundry is dehydrated by centrifugal force, and at the same time, the washing water is heated by the heater to form heat, and when the drum rotates, Due to the warm air is formed, the moisture of the laundry is evaporated by the warm air, so that the laundry is semi-dried faster than when the laundry is dried by centrifugal force.

In addition, since the warmth remains in the laundry even after washing of the laundry until the semi-drying stroke, the dryness of the laundry is improved by condensing and drying the laundry water due to a difference from the external temperature when the laundry is taken out and washed.

Finally, the finishing foaming step (S40) by dropping the laundry from the wall surface of the drum and releasing the tangling of the laundry so that the user can easily take out the laundry one by one to hang on the drying rack (S20, S20) It is carried out in the same way as').

As described above, the semi-drying method of the washing machine according to the present invention is slightly dried in a state in which the laundry is gradually dehydrated, that is, dried to 55 to 70%, and the laundry is entangled by alternately performing dehydration and foaming of the laundry. Because it is often released, the laundry can be dried in a short time outside or in the room, and the clothes can be ironed immediately without drying the clothes.The washing time is not severe and the ironing time can be shortened. It doesn't have a smoky odor due to prolonged drying by hot air.

In particular, in the present invention, the laundry is dehydrated by centrifugal force in the present dehydration step (S30), and at the same time, since the moisture of the laundry is evaporated by the warm air, the laundry is not only quickly dried but also the dryness of the laundry is high.

The semi-drying method of the washing machine according to the present invention constituted as described above includes a simple dehydration step in which the laundry is first dehydrated by centrifugal force while the washing tank is rotated at a constant speed, and an initial folding step in which the washing tank is stirred and rotated after the simple dehydration step. The main dewatering step, in which the washing tank is rotated at a higher speed than the simple dewatering step after the initial inflating step, and the wash water supplied to the heater to be heated, is heated by the heater so that the laundry is secondarily dehydrated by centrifugal force and warm air. After the dehydration step, the washing tank is stirred and rotated, so the tangles of the laundry are released.They have almost no creases of the laundry, and the laundry is slightly less curled so that the laundry can be dried naturally in a short time as well as ironed. There is an advantage that can be worn immediately.

In addition, the present invention has the advantage that the laundry can be semi-dried more quickly because the laundry is dehydrated by centrifugal force and the water is evaporated by the warm air at the same time in the dehydration step.
