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 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 squishy 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 stirring and rotating so that the laundry is tangled.

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

Semi-drying method of the washing machine according to the present invention is a simple dehydration step (S10, S10 ') and the simple dewatering step of the washing tank is rotated at low speed so that the laundry is dewatered by the centrifugal force if the amount of eccentric laundry accumulated in the washing tank is within the allowable range. After (S10, S10 '), the initial bathing step (S20, S20') and the washing tank is stirred and rotated to loosen the laundry tangling, and after the initial inflating step (S20, S20 '), the laundry by centrifugal force The dehydration step (S30) that the washing tank is rotated at a high speed so as to dry about 55 to 70% by secondary dehydration (S30), and after the main dehydration step (S30), the finishing bathing step in which the washing tank is stirred and rotated to loosen the laundry is tangled (S40). Composed of, the laundry is dehydrated step by step to dry 55-70% but to minimize the wrinkle of the laundry.

Specifically, after the rinsing cycle, when the laundry is entangled with each other and placed on one side of the washing tank and the motor is driven at the set primary dehydration speed, that is, 600 to 900 rpm, the vibration of the washing tank becomes excessive due to the weight eccentricity of the washing tank and makes noise. Not only this, but the washing machine can be broken.

Therefore, the simple dehydration step (S10, S10 ') is attached to the wall of the washing tank without falling by the gravity during the rotation of the washing tank to detect the amount of eccentricity of the laundry through the change of the load on the motor for one cycle The eccentric detection process S12 in which the motor is driven for about 1 minute at a critical speed, that is, a minimum speed of 350 rpm, is performed first.

Then, if the amount of eccentricity of the laundry is within the allowable range, it is attached to the wall of the washing tank to be dehydrated by centrifugal force so that the laundry does not fall due to gravity when the washing tank is rotated, and the laundry does not get caught in the hand of the washing tank by the centrifugal force. The primary dehydration process (S14) driven at the set dehydration speed is performed.

In the primary dehydration process (S14), the heavier the laundry is, the greater the centrifugal force of the laundry acts so that the laundry is compressed on the wall of the washing tub to prevent the laundry from being caught in the hand of the washing tub at a relatively low speed of 600 ~ 900rpm If the motor is driven at a low speed, there is a limit to dehydrating laundry as desired.

Therefore, the simple dehydration step (S10, S10 ') is carried out in a plurality of times alternately with the initial inflating step (S20, S20'), but is performed a plurality of times because the water content of the laundry gradually decreases as each time is performed. Accordingly, the primary dehydration speed and the primary dehydration time of the motor are set to increase step by step, so that the laundry is dehydrated step by step so that the laundry does not get caught in the hand of the washing tank even if the washing tank is rotated at high speed in the present dehydration step (S30).

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 inflated step (S20, S20 ') is the laundry is moved in the primary dehydration process (S14) laundry is moved, the laundry can be more tangled and agglomerated and the degree of dehydration of the laundry is different depending on the type of laundry Since the laundry is attached to the wall of the washing tank even after the washing tank is stopped, the motor is turned on and off according to the duty set so that the washing tank is stirred and rotated, and it is alternately driven in the forward / reverse direction so that the laundry falls from the wall of the washing tank. In addition, it is deposited evenly without biasing to one side.

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

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 If it is within, the secondary dehydration process (S34) and the secondary dewatering process (S34) driven for about 13 minutes at a secondary dehydration speed, that is, 1200rpm so that the laundry is secondary dewatered by centrifugal force to dry 55-70% or so, and after the secondary dehydration process (S34) By the power of the motor is made of a process (S36) that the drying of the laundry is extended for a short time.

In the secondary dehydration process (S34), the laundry is dehydrated in the primary dehydration step (S10, S10 '), and is relatively light, and the laundry is rotated at high speed because the tangle is released in the initial inflating step (S20, S20'). The centrifugal force is attached to the wall of the washing tank and dried, but is not caught in the hand of the washing tank, so that the laundry may be dried slightly less dry without almost wrinkles even when the washing tank is rotated at high speed for a long time.

Next, the finishing foaming step (S40) is carried out in the same manner as the initial inflating step (S20, S20 '), and finally the user can easily wash the laundry by releasing the laundry and tangling the laundry from the wall of the washing tank Take them out one by one so that they can be hung on the drying rack.

Therefore, in the present invention, the laundry is dehydrated and swollen for about 30 minutes, and the laundry is dried to a degree of drying of 55 to 70% step by step, and the laundry is frequently entangled, so that the laundry is whipped outside or in the room for a short time. Not only can it be dried, but the clothes can be ironed and dried without natural drying, and since the wrinkles of the laundry are not severe, ironing time can be reduced, and a smelly smell caused by long-term drying by hot air in a closed space in the laundry can also occur. Do not.

In the semi-drying method of the washing machine according to the present invention configured as described above, if the amount of eccentricity of the laundry is within the allowable range, the simple dewatering step in which the laundry is first dehydrated by centrifugal force, and the washing tank is tangled as the washing tank is stirred and rotated after the simple dewatering step. The initial defoaming step of releasing, and after the initial defoaming step, the laundry is secondly dehydrated by centrifugal force to dehydrate the secondary to 55-70% level of dryness, and to release the tangling of the laundry after the main dehydration step. There is almost no crease of the laundry because it is made of the finish poultry step, the laundry is slightly less curled state can not only dry the laundry in a short time, but also has the advantage of ironing can be worn immediately.
