Description

How to improve the rinsing power of the washing machine

The present invention relates to a method for improving the rinsing power of a washing machine, and in particular, normal dehydration after removing the detergent remaining in the laundry or the washing tank and the low water irradiator between the laundry after the completion of the balance dehydration during the rinsing operation that proceeds after the completion of the washing process. By proceeding, the present invention relates to a method for improving the rinsing power of a washing machine to improve the rinsing power during the rinsing stroke.

In general, a washing machine performs a rinsing stroke to improve the washing power when the washing stroke is completed. In this case, the rinsing stroke is normally performed twice, and each rinsing stroke is drained and drained every time the rinsing is completed. Afterwards, balance dewatering is performed for an arbitrarily set time in order to release the unbalance due to the kink generated by the rotational friction force and to remove the contaminated washing water and detergent absorbed in the laundry during washing or rinsing. Immediately after completion of dehydration, normal dehydration is to proceed and complete.

As such, the balanced dewatering and normal dehydration performed every rinsing stroke are separated by rotating centrifugal force from the uncleaned detergent or detergent removed between the contaminated wash water and the laundry absorbed by the laundry during the washing and rinsing. In order to improve the rinsing power, the balanced dewatering and normal dehydration compresses the laundry with the wall surface of the washing tank by the rotational centrifugal force, so that the detergent stuck between the laundry or the washing tank and the water tank when draining the balance dewatering Dehydration is made without actually discharging the non-discharged product, and the rinsing stroke has a problem in that it cannot improve the rinsing power to a desired degree.

An object of the present invention is that when the balance dehydration is carried out during the rinsing stroke, the balance dewater is completed, watered for a predetermined time and then drained, and when the drainage is completed, by rinsing while proceeding normal dehydration, the balance dehydration is completed After the water is drained and the detergent is sandwiched between the laundry by the water supply and drained water and the remaining detergent removed between the washing tank and the water reservoir is to be dehydrated normally, so as to improve the rinsing power when rinsing administration.

In order to achieve the above object, the present invention provides a washing process in the initialization state, the washing process is completed, when the water supply is completed during the rinsing stroke, rinsing the pulsator forward and reverse rotation, and when the rinsing is completed, unbalanced after draining A step of proceeding to release the balance dewatering, determining whether the balance dewater has been completed in the step, if the balance dehydration is completed, stopping and dewatering the dehydration, and draining when water supply is completed in the step; When the drainage is completed in the step, but proceeds to normal dehydration is characterized in that it consists of proceeding until the normal dehydration is completed.

Referring to the operation of the present invention made as described above are as follows.

First, the power is supplied to the washing machine, and the laundry signal to be washed is put in the washing tank 2, and the driving signal input unit sets a series of washing administrations to be operated through the microcomputer (B). In b), the water supply level according to the washing amount is determined by a predetermined program according to the input operation signal.

When the water supply level is determined, the microcomputer (b) supplies water to the washing tank 2 by controlling the water supply and drainage drive unit C, and also controls the water level detection unit d to supply water through the water level sensor 7. When the water supply is sensed and the water supply is completed, the microcomputer (b) controls the motor driving unit (e) to rotate the motor 5 forward and reverse to drive the pulsator 3 through the gear unit 4. After the washing is performed in the forward and reverse directions, and then the washing is in progress, the contaminated washing water generated during washing is drained, and then, the rinsing proceeds to the rinsing step 32 to control the water supply and drainage unit (C) to rinse. The water is supplied to the water level determined during the washing administration, and when the water supply is completed, the motor driving part (e) is controlled to rinse while the pulsator 3 is rotated forward and backward, and then the rinse is completed in the microcomputer (b). Go to step 33 It is determined whether the ongoing rinsing is completed. If the ongoing rinsing is not completed, the rinsing is continuously performed. If the ongoing rinsing is completed, the rinsing is controlled to drain the contaminated washing water generated during the rinsing. In order to improve the rinsing power and release the unbalance of the laundry generated during rinsing, go to the balance dewatering step 34 and control the motor 5 through a motor driving part e to set the washing tank 2 arbitrarily. (30 seconds) by rotating at a randomly set number of revolutions (400rpm) to advance the balance dewater.

While the balance dehydration proceeds as described above, the microcomputer (b) goes to the balance dehydration completion determination step 35 to determine whether the balance dehydration is completed, and if the balance dewater is not completed, the balance dewater is completed. Balanced dehydration proceeds until the balance dewatering is completed, the microcomputer (b) goes to the balance dehydration stop step 36 to control the motor drive unit (e) to stop the rotation of the motor 5, Stop, and then go to the water supply step 37 to control the water supply and drainage drive (c) to close the drain opening that is open during dehydration, and to supply water to the washing tank (2), for a predetermined time (1 minute) When the water supply is complete, the microcomputer (b) goes to the drainage step 38 and controls the water supply and drainage drive unit (c) to wash the water supplied for the arbitrarily set time. By allowing a multiple donor is washed with the detergent foam remaining between sandwiched between the laundry by a washing detergent and the washing tank in which waste water (2) and the reservoir (1).

On the other hand, when the drainage is completed in the drainage step 38, the microcomputer (b) goes to the normal dehydration step 39 and controls the motor 5 through the motor driving part (e) to rotate the washing tank 2 at high speed while being normal. While the dehydration is performed, the microcomputer (b) goes to the normal dehydration completion step 40 to determine whether the normal dehydration is completed while the normal dehydration is in progress. In the microcomputer (b), dehydration is continued until the normal dehydration is completed. On the other hand, when the normal dehydration is completed, the motor drive unit (e) is controlled to stop the dehydration and proceed to the next stroke.

As described above, in the present invention, when the balance dehydration to be performed during the rinsing stroke is completed, water is supplied for a predetermined time and then drained, followed by rinsing while proceeding with normal dehydration. Detergents sandwiched between the laundry and the remaining detergent is removed between the washing tank and the water reservoir will provide an effect that can improve the rinsing power than rinsing administration.
