Description

How to wash your washing machine

The present invention relates to a washing method of a washing machine, and in particular, washing the washing machine to proceed with a series of washing strokes arbitrarily set according to the detected water level deviation by detecting a water level deviation that varies depending on the type and amount of laundry in the initial stage of washing. It is about a method.

In general, when the laundry is to be washed in a washing machine, the washing is performed while water is supplied at an appropriate level according to the amount of the laundry.

Therefore, in order to supply water at an appropriate level according to the amount of washing during washing, the amount of laundry to be washed must be sensed. According to the conventional method of detecting the amount of washing to be washed, that is, detecting the amount of laundry, a predetermined amount of laundry is put in a washing tank. After supplying water to the water level, the pulsator is rotated by a predetermined number of times, while rotating the pulsator to detect the amount of washing in a load state acting on the washing motor rotating the pulsator.

However, when the washing water level is determined as the load state acting on the washing motor according to the washing amount, the load state acting on the washing motor is different depending on the fiber type of the laundry and the amount of the kind. Nylon, synthetic fibers, cotton, or blanket is not only a difference in the amount of absorbed wash water, but also a significant difference occurs depending on the amount.

Therefore, when the washing is carried out after the water is substantially supplied to the water level determined according to the washing amount, when the water level is largely varied according to the fiber type and the amount of the laundry, that is, when the laundry has a lot of cotton-type fibers, the washing water The water absorbed water is insufficient, so that the water wash water is insufficient. If there is a lot of synthetic fibers and nylon, the water absorbed water is less absorbed due to the increase in the number of wash water, or washing is progressed by the laundry administration already set up in a insufficient state. Not only can not achieve the desired washing effect due to lack of water, but also has the problem that causes damage to the laundry by the water flow friction.

An object of the present invention is to supply the water level to one level or less than the water level determined according to the amount of laundry to be washed at the beginning of the washing, then rotate the pulsator to detect the water level and the deviation between the detected water level and the water level to the water level below the one level It is intended to wash laundry according to the fiber type and amount of the laundry by calculating and setting a series of washing operations according to the calculated deviation.

In order to achieve the above object, the present invention initially detects the amount of laundry in the state to put the laundry to be washed in the washing tank to determine the water level according to the detected amount of washing and watering the water level in one step or less, When the water supply is completed one step or less than the water level determined in the step, the step of detecting the water level after the reverse rotation of the pulsator for a randomly set time, and calculating the deviation between the water level detected in the step and the water level below the one level And setting a series of washing strokes corresponding to the deviation calculated in the step, and proceeding with washing by the set washing stroke.

A pulsator drive completion step (35) for determining whether the drive is completed for a time T arbitrarily set in the pulsator drive step (34); and the pulsator drive Judgment When the pulsator drive is completed in (35), the water level detection step 36 for detecting the washing water level P2 in the current state, and the washing water level P2 detected in the water level detection step 36 and one step higher than the determined water level The level deviation calculation step 37 for calculating the level deviation ΔP1 with respect to the water level P2 and the level deviation ΔP1 calculated in the level deviation calculation 37 are the same as the level deviation ΔP2 arbitrarily set. When the water level deviation determination step 38 for determining a small value and the water level deviation ΔP1 calculated in the water level deviation determination step 38 are equal to or lower than an arbitrarily set water level deviation ΔP2, a series of washings corresponding to the determined water level If the first washing step 39 and the water level deviation ΔP1 calculated in the water level deviation determination step 38 are more than the arbitrarily set water level deviation ΔP2, the type and amount of the laundry are determined to be large. A series of laundry administration laundry Liver, is to consist of a second washing step 40 for washing by the washing time longer than the reset, the number of rinsing, dehydration time.

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

First, the laundry to be washed is put in the washing tank 2 of the washing machine in the state where the washing machine is initialized, and when the washing start signal is inputted through the operation signal input unit, the microcomputer (b) detects the quantity by the input washing start signal. Go to step 30 to control the water supply and drain drive unit (c) to determine the water level for the laundry put into the washing tank (2) to supply water to a predetermined predetermined water level, and then through the motor driving unit (e) washing motor ( 5) and the driving force of the washing motor 5 is the load sensing unit (bar) in a load state acting on the washing motor 5 by rotating the pulsator 3 forward and backward through the gear unit 4. It is detected through.

When the quantity is detected through the quantity detecting unit (bar) as described above, the microcomputer (b) goes to the water level determination step 31 to determine the water supply level by a predetermined program predetermined for the detected quantity. If the water supply level is determined, go to the water supply step 32 to control the water supply and drainage drive (C) to proceed with the water supply, at which time the water supply (P1) to proceed to one level or less for the determined water level by a predetermined program Subsequently, when the water supply is completed in one step or less water supply (P1), the microcomputer (b) goes to the water supply stop step 33 to control the water supply and drain drive (C) to stop the water supply, the pulsator driving step 34 By controlling the motor drive unit (e) to rotate the pulsator (3) forward and backward for a randomly set time (T) so that the wash water is evenly absorbed in the laundry.

In this way, while the pulsator 3 is rotated forward and backward for an arbitrarily set time T, the microcomputer (b) goes to the pulsator drive completion determination step 35 and the time when the forward and reverse rotation of the pulsator is in progress is arbitrarily set. It is determined whether (T) is completed. At this time, if the arbitrarily set time (T) is not completed, the pulsator (3) is continuously rotated forward and backward, while if the randomly set time (T) is completed, The microcomputer (b) goes to the water level sensing step 36 to sense the current level P2 of the washing tank 2 through the water level sensing unit (d), and then the randomly set time T in the microcomputer (b). It is detected how much the water level change (P2) is generated for the water level supplied to the water level below one step.

When the water level change P2 is detected as described above, the microcomputer (b) goes to the water level deviation calculation step 37 to calculate the water level deviation ΔP1 between the water supply level P1 and the detected water level P2. Go to the water level deviation judging step 38 with respect to the calculated water level deviation ΔP1, and how much water level deviation occurred, that is, how much cotton type or amount, nylon and synthetic fibers are contained in the laundry to be washed. It is determined whether the calculated water level deviation ΔP1 is equal to or less than the arbitrarily set water level deviation ΔP2 in order to calculate the water level deviation generated according to the above. In this case, the water level deviation ΔP1 is arbitrarily set. If (ΔP2) is the same or smaller, the microcomputer (b) determines that there is little change in the wash water absorption due to an appropriate type and amount of laundry to be washed at the first washing step 39. Go to set the washing process according to the preset washing cycle, washing time, washing time, rinsing frequency, dehydration time, while the water level deviation ΔP1 is determined as determined by the level deviation determination step 38. If the water level is greater than the set ΔP2, the microcomputer (b) determines that the type and amount of the laundry to be washed currently absorbs the wash water, and thus, the change in absorption of the wash water is large. Go to 40) and reset the washing time, washing time, rinsing frequency, and dehydration time, which is a preset series of washing administrations.

As described above, the present invention initially detects the washing amount in the state in which the laundry to be washed is put in the washing tank, determines the water level, and then supplies water to the determined water level in one step or less, and then reverses and rotates the pulsator for a predetermined time. After detecting the water level and calculating the deviation between the detected water level and the water level supplied to the water level below the one step, and by setting and resetting a series of washing strokes corresponding to the calculated water level deviation, the laundry by proceeding, Depending on the type and amount of the water is not supplied to the appropriate water level will provide an effect that can be washed while washing while preventing the washing effect or damage to the laundry.
