Description

How to wash your washing machine

The present invention relates to a washing method of a washing machine, and more particularly, to a washing method of washing the laundry to be uniformly performed by washing the laundry while turning the laundry up and down once in the washing tank.

In general, when washing with a washing machine, water is supplied to the laundry level determined for the laundry, and the washing is performed by the water flow friction generated from the pulsator rotating the forward and reverse by rotating the pulsator forward and backward at a predetermined predetermined rotation speed. It is supposed to be.

However, irrespective of the laundry put into the laundry and the state in which the laundry is placed, the washing machine rotates forward and backward by a predetermined time. For example, when the washing amount is small, the load acting on the pulsator is small, and the pulsator rotates forward and reverse. When the washing force is strong, the washing effect can be improved by inverting the laundry located at the top and the laundry located at the bottom of the washing tank during washing, thereby improving the washing effect on the entire laundry. Since the rotational force of the pulsator rotating forward and reverse becomes weak, the laundry placed in the lower part of the washing tank is washed while the water flow friction is applied by the forward and reverse rotation of the pulsator, but the laundry placed on the upper part of the washing tank In the case of pulsator, forward and reverse power is weakly transmitted. This movement becomes small, therefore the washing be done while the water flow is weak frictional force acting washing effect of the laundry in the laundry and a lower end located in the upper portion of the washing tank is made as a whole prevents any laundry evenly generated difference.

Nevertheless, in the conventional laundry method, when a lot of the laundry is washed, there is almost no separate device or method for overturning the laundry located at the top and the laundry located at the bottom. Looking at the laundry state of the laundry, there is a problem that often occurs when washing the laundry on the upper side and the laundry located on the lower side artificially.

An object of the present invention is to rotate the pulsator to turn the pulsator to turn over the water after washing the pulsator to the water level friction while washing the pulsator forward and reverse rotation during the washing, and then to turn the pulsator to turn the water back to the determined water level again By doing the laundry after, to ensure that the laundry evenly wash the entire laundry.

In order to realize the above object, the present invention initially detects a quantity of laundry in a state in which laundry to be washed is put in a washing tank, and determines a water supply level according to the detected quantity of water, and supplies water to the determined water level and completes water supply. And, when the water supply is completed in the step, washing the washing motor while rotating the pulsator by rotating the washing motor forward, and determining whether the predetermined predetermined drainage time during the washing in the step has been reached, and optionally set in the step If the predetermined drainage time has been reached, draining to a predetermined level, which is arbitrarily set; determining whether the level to be drained at the step reaches a predetermined drainage level; and wherein the predetermined drainage level is arbitrarily set. When the water level is reached, the pulsator can be set at random Stabilizing and turning the laundry to reverse, and if the laundry is turned over for a predetermined time in the step, resupplying to the determined level, and if the resupply is completed at the determined level, the pulsator is settled. It is characterized in that it consists of a step of re-washing until the washing is completed while rotating in reverse and completing at a predetermined washing 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 while the washing machine is initialized, and when the washing start signal is inputted through the operation signal input unit A, the microcomputer (b) goes to the quantity detection step 30 and is inputted. By controlling the motor driving part (e) with respect to the amount of washing, the amount of load (capacity) is sensed by the load acting on the washing motor 5 while the pulsator 3 is rotated forward and backward. Go to step 31 to determine the water level for the detected amount of water and then go to the water supply step 32 to control the water supply and drainage drive (c) to proceed with the water supply to the determined water level, the water level is water level detection unit It detects through) and supplies to the determined water level and completes it.

When the water supply is completed as described above, the microcomputer (b) goes to the washing step 33 to control the motor driving part (e) to rotate the motor 5 forward and reverse and the pulsator 3 through the gear part 4. Rotate to proceed with the washing.

As described above, during the washing process, the microcomputer (b) determines whether a predetermined drainage time set in the drainage time determination step 34 is reached. In step), the washing step 33 proceeds to the washing process, while on the other hand, if the predetermined drainage time set in the drainage time determining step 34 is reached, the draining step 35 goes to the water supply and drain driving unit (C Open the drain 7 to control the drainage, but the drainage level is drained while detecting the drainage level through the water level detection unit (d), the microcomputer (b) is drained to the drainage level determination step 36 It is determined whether the water level has been drained to a predetermined level which is arbitrarily set. At this time, if the determined level is not drained to a predetermined level, continue. When the drainage level reaches the predetermined drainage level, which is set at random, the microcomputer (b) stops the drainage by controlling the water supply and drainage drive (c) and goes to the laundry flipping step 37. By controlling the motor driving part (e), the pulsator 3 is rotated forward and reverse at randomly set time and number of times (forward rotation 5 seconds on, 1 second off, reverse rotation 5 seconds on, 1 second off 5 times) to the laundry. The friction force acts largely to turn over the laundry located in the upper and lower parts of the washing tank (2).

When the laundry is turned over as described above, the microcomputer (b) goes to the water supply step 38 to control the water supply and drainage drive unit (c) to supply water to the determined water level, and then the water supply is completed at the determined water level. (B) Go to the re-washing step (39) to control the motor drive (e) to re-wash the pulsator (3) forward and reverse rotation.

Meanwhile, as described above, the microcomputer (b) goes to the washing completion determination step 40 to determine whether the preset washing time is completed. In this case, the ongoing rewashing is not completed at the preset washing time. If not, the washing process continues, while if the rewashing is completed at the preset washing time, the washing is completed and the next administration is performed.

As described above, in the present invention, when the washing is performed with water flow friction while washing the pulsator forward and reverse, the washing water level is drained to a predetermined predetermined level during washing, and then the pulsator is rotated to flip the laundry and then the water level is determined again. By re-watering to wash the laundry, while washing the water flow friction evenly throughout the laundry during the laundry will provide an effect that can improve the washing effect evenly throughout the laundry.
