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 for dehydrating laundry by step centrifugal force and simultaneously releasing the tangling of the laundry to dry the laundry to 55 to 70%.

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, the front of the cabinet (2) in the detergent box 16 to store the detergent so that the detergent is supplied to the tub (6) and the drum (8) with the washing water at the time of washing, the controller for controlling the operation of the washing machine 18 is installed, the heater 20 for heating the washing water is installed on the inner bottom surface of the tub 6, the inner surface of the drum 8 to wash the laundry at a certain height during rotation of the drum (8) Lift 22 to be installed is installed.

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 occur, and the laundry is severely wrinkled, and the laundry is dried and after-treatment such as ironing There is a problem that requires a process.

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 of rotating the laundry tank at a constant speed so that the laundry is first dehydrated by centrifugal force if the amount of eccentricity of the laundry accumulated in the washing tank is within an allowable range; After the simple dewatering step, the initial bathing step of rotating the washing tank stirring to loosen the laundry tangling; After the initial inflated 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 dehydration step, the washing tank is composed of a finishing bubble expansion step of rotating the stirring to loosen the laundry,

In particular, if the semi-dry course is set when the washing course is set, the rinsing stroke is characterized in that the washing water heating process for heating the rinsing wash water supplied to the washing tank.

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

In the washing method of the semi-dry course of the washing machine according to the present invention, when the user selects the type of laundry and hot / cold water, and the semi-dry course by operating a controller installed in the exterior of the washing machine, the washing pattern according to If the user presses the operation button after the setting stroke (A) is set and the washing pattern is set (B), the washing water is supplied to the washing tank in which the laundry is stored, and the washing tank is rotated and the chemical reaction of the detergent and the water flow and the laundry are rotated. Washing stroke (C) to remove the time of the laundry by the frictional force, and when the contaminated wash water is drained after the washing stroke (C), the washing water is supplied again and the washing tank is rotated, the rinsing stroke (D), When the contaminated washing water is drained from the rinsing stroke (D), the washing tank is rotated according to a semi-dry course algorithm, so that the laundry is slightly dried, that is, drying degree 55 to It consists of a semi dry stroke (E) which is dried to a level of 70%.

In particular, the rinsing stroke (D) is repeated at least three times the water supply (d1) -drainage (d2) process several times so that the laundry is sufficiently rinsed as shown in Figure 4, the semi-dry course in the setting step If is selected, the washing water heating process (d3) for heating the washing water to 35 ℃ to 45 ℃ by operating on the electric heater installed in the washing tank after the last water supply process is characterized in that it is further included.

As a result, since the laundry is rinsed with warm wash water, the detergent and the foreign matter dipped in the laundry are well separated from the laundry, thereby improving the rinsing performance of the laundry.

In addition, since the warmth remains inside the washing tank during the semi-drying stroke (E), when the washing tub rotates according to the semi-drying algorithm, the laundry is not only dried better by centrifugal force but also by warm air, Wrinkles are effective in spreading.

In addition, since the warmth remains in the laundry even after all the strokes of the washing machine are completed, when the laundry is taken out from the washing tub and whisked out, the warmth of the laundry warms the laundry so that the laundry is sufficiently dried. As a result, the water of the laundry is condensed and dried to improve the dryness of the laundry.

Meanwhile, as shown in FIGS. 5 and 6, the semi-dry stroke E detects an eccentric amount of laundry according to a change in load applied to the motor for one cycle while driving the motor for rotating the washing tank for about 350 rpm for a short time. If the eccentricity detection process (S12) and the amount of eccentricity of the laundry is within the allowable range, the simple dehydration consisting of a primary dewatering process (S14) that the motor is driven at a low speed 600 ~ 900rpm for 30 seconds to 3 minutes so that the laundry is first dewatered by centrifugal force Step (S10, S10 '), and after the simple dehydration step (S10, S10') by stirring the rotation of the washing tank to release the initial entanglement of the laundry tangling (S20, S20 '), and the initial folding step (S20 (S20 ') and then detect the amount of eccentricity of the laundry in the same manner as the simple dehydration step (S10, S10'), if the amount of eccentricity of the laundry is within the allowable range, the laundry is secondarily dehydrated by centrifugal force to dry slightly less, This dehydration step (S30) and the motor is driven at a high speed of about 1200rpm for about 13 minutes to dry to 55 ~ 70% dryness level, and after the main dehydration step (S30), the washing tank is stirred and rotated so that the laundry is tangled Inflated step (S40) is made.

Here, the heavier the laundry, the more the influence of the centrifugal force. Therefore, to prevent the laundry from being caught in the hand of the washing tank, the motor should be driven at a low speed. Steps S10 and S10 'may be performed a plurality of times alternately with the initial inflating steps S20 and S20', but as the water content of the laundry gradually decreases as each time is performed, the speed and speed of the motor may be increased. The driving time is set to increase step by step.

In the present dehydration step (S30), the laundry is dehydrated primarily through the simple dehydration step (S10, S10 '), and is relatively light, and the motor is evenly stacked through the initial inflating step (S20, S20'). Even if driven by the laundry can be sufficiently dehydrated without being caught in the hand of the washing tank by centrifugal force.

Therefore, the semi-drying process as described above, the laundry is dehydrated and swollen for about 30 minutes alternately, the laundry is dried to 55 ~ 70% of the drying step by step, and the laundry is often entangled, so the laundry is outside the laundry. In addition to being able to dry in a room for a short time, the clothes can be ironed immediately without being naturally dried, and the washing time is not severe, so the ironing time can be reduced. It doesn't smell too dry.

 According to the present invention configured as described above, when the semi-dry course is set, the washing water is heated after the last water supply in the rinsing cycle, so that the laundry is rinsed with warm washing water, and the detergent and foreign substances dipped in the laundry are well separated from the laundry to rinse the laundry. When the performance is improved and the laundry is withdrawn from the washing tub, the user may feel that the laundry is sufficiently dried due to the warm warmth of the laundry, and thus the emotional quality may be improved.

In addition, since the warmth remains inside the washing tank during the semi-drying operation, warm air is formed when the washing tank is rotated, and the laundry is dried by hot air as well as centrifugal force. Since the moisture of the laundry is condensed and dried by the temperature difference from the outside, the dryness of the laundry may be improved.
