Description

How to remove lint from a washing machine

The present invention relates to an apparatus and method for removing lint from a washing machine, and more particularly, to an apparatus and method for removing lint from a laundry during a series of laundry administrations.

In general, a washing machine includes washing by rotating a pulsator and washing by rotating a washing tank, but in the case of washing by rotating the pulsator, the washing machine includes a lint collecting device that filters lint generated from laundry during washing and rinsing. On the other hand, the washing machine that rotates the washing tub is not equipped with a lint collecting device to prevent the removal of the lint generated from the laundry during washing and rinsing.

Therefore, the washing machine that rotates the washing tub and washes the washing tub 2 suspended from the damper 15 inside the washing machine 1 and the hub 14 of the laundry tub 2 as shown in FIG. 1. Rotor 5 formed in the motor (3) engaging the stator (4), drive shaft 6 is coupled to the rotor 5 and rotated, and coupled to the end of the drive shaft (6) to rotate A washing tank 8 installed in the washing outer tank 2, a pulsator 7 installed on the bottom surface of the washing tank 8, and stirring the laundry, and protruding into the inner circumference of the washing tank 8 and contacting the laundry. A plurality of washing stones (9), a plurality of washing holes (10) formed at the periphery of the washing tank (8) to circulate the washing water, and the washings gathered into the washing outer tub (2) through the washing holes (10). It is composed of a drain hose 13 for discharging the water to the outside by the drain pump (12).

The washing machine configured as described above puts the laundry into the washing tank 8 for washing, and when the washing starts, the water is supplied to the washing tank 8 and when the water level is supplied according to the amount of washing water, the water is cut off and the motor ( 3) is running while washing.

That is, the stator 4 formed on the motor 3 is fixed to the hub 14, and the rotor 5 is fixed to the drive shaft 6 connected to the washing tub 8, and thus is electrically connected to the motor 3. When the signal is applied, the washing tub 8 connected to the drive shaft 6 is rotated by the rotation of the rotor 5 to wash.

In this case, the laundry contained in the washing tub 8 may be washed while friction resistance is generated due to the contact between the pulsator 7 and the washing protrusions 9 that rotate together with the washing tub 8.

In addition, the plurality of washing holes 10 formed in the washing tank 8 serve to discharge the washing water to the washing outer tank 2, so that washing is possible by circulation of the washing water.

Subsequently, when the washing stroke is completed, a dehydration stroke is performed to remove the sewage absorbed in the laundry. In this case, the washing water in the washing tank 8 is washed by the washing tank 8 rotated at a high speed by the motor 3. The plurality of washing holes 10 are discharged to the washing tub 2, and the discharged washing water is drained to the outside through the drain hose 13 by the drain pump 12.

As such, the washing machine does not have a lint collecting device that filters lint generated by abrasion of laundry during washing, and thus the lint remains on the laundry after washing is completed.

Therefore, in order to solve the above problem, there is a part of the lint generated from the laundry by rinsing while additionally watering the water in the rinsing stroke of the series of washing strokes of the washing machine.

That is, as shown in Figure 2, when washing is started, it is determined whether the water supply rinse 20 is selected, and if the water supply rinse 20 is not selected, the washing administration 21 to wash and complete, and When the washing stroke 21 is completed, the process of performing a dehydration stroke 23 after draining and dehydrating again after the completion of the water supply to the rinsing water level, rinsing and completing the rinsing stroke 22 and the rinsing stroke 22 is completed. The washing will end.

On the other hand, if the water supply rinsing 20 is selected, the washing stroke 24 to wash and complete, and when the washing stroke 24 is completed, drained and dehydrated, and then watered again to the rinsing water level, the water supply is set at random Rinsing stroke 25 to rinse and complete while progressing, and when the rinse stroke 25 is completed, the washing process is to be completed by the process of performing the dehydration stroke (26).

Thus, in the conventional water rinsing method, since the water rinsing proceeds when the user rinses only when the user selects the water rinsing at the beginning of washing, lint can be removed.

However, when the user does not select the water rinsing, the lint is not easily discharged, so after the end of the washing, the lint may be buried in the laundry, and thus, the rinsing may not be performed. In order to use the water rinsing button several times in order to have a hassle.

In the washing, rinsing, and dehydration, the speed control is performed by adjusting the on / off time of the motor in the case of a general induction motor, or controlling the phase angle as disclosed in Patent Publication No. 1997-006602, or in the case of a BLDC motor or an SRM motor. As disclosed in Patent Publication Nos. 1995-032825 and 1996-014491, PWM control is performed.

An object of the present invention is to wash the dust generated from the laundry during washing or rinsing in a series of washing strokes by rotating the motor at a high speed and a high speed for a predetermined time during the washing stroke or rinsing stroke or washing and rinsing stroke. And by performing the rinsing, by the high speed centrifugal force more lint is easily discharged and removed to obtain a clean laundry effect.

In order to achieve the above object, the device of the present invention is suspended during washing or rinsing on a top of a washing tank equipped with a washing hole for circulating the washing water and discharging generated lint during washing or rinsing during a series of washing, rinsing, and dehydrating administration. A rectangular lint discharge port is formed so that more lint is discharged, and the laundry hole is formed by sequentially forming a large diameter while going from the bottom to the top.

Method of the present invention for realizing the above object is a series of washing, rinsing, dehydration stroke in the washing stroke or rinsing stroke or washing and rinsing stroke during the water supply is completed, after the general washing or general rinse It is characterized in that it is made to include a high-speed rotary washing or a high-speed rotary rinsing or a high-speed rotary washing and a high-speed rotary rinsing to wash and rinse by rotating the driving time and rotational speed of the motor for a predetermined time and a high speed.
