Description

How to dehydrate the washing machine

The present invention relates to a dehydration method of a washing machine, and in particular, when dehydration is performed by selecting only a dehydration stroke out of a series of washing strokes, when dehydration occurs during dehydration, water is supplied to a water level corresponding to a washing amount (dehydration amount), and then dewatering is released. It is about the dehydration method of the washing machine to be able.

In general, in the case of a washing machine, a user can select and wash a series of washing administrations, namely, washing, rinsing, and dehydration.

Therefore, when the user wants to wash a relatively light type of laundry (handkerchief, socks, underwear) and the like, there are cases where the user washes using a washing machine, or the user only wants to dehydrate after washing by hand.

Thus, when the user manually washes a relatively light type of laundry and then dehydrates only the dehydration stroke of the washing machine in order to dehydrate only the washing machine, when the unbalance occurs during dehydration, the washing machine stops dehydration and generates The water is supplied to release the unbalance, and the water is supplied to release the unbalance and dewater again while the pulsator is rotated forward and backward. Thus, when the unbalance occurs, the level of water supplied to release the unbalance is usually a preset water level. In this case, water is supplied at a high or medium water level.In this case, water is supplied in large quantities compared to the amount of washing, and the pulsator is rotated forward and reverse to release unbalance and dewatering. Not only is there waste of water, In addition, a lot of energy is lost.

An object of the present invention is to select the dehydration only in a series of laundry administration for a relatively light type of laundry, when unbalance occurs during the dehydration water supply to a very low level to detect the washing amount, that is, the dehydration amount and the detected dehydration amount In order to reduce the waste of water and time by dehydration while releasing unbalance after watering according to.

In order to realize the above object, the present invention provides a method for determining dehydration during dehydration in a state in which only dehydration is used in a series of washing operations, and dehydration if unbalance occurs in the dehydration step; If debalance occurs in the step, stop dehydration, water supply to a very low water level, detecting the washing amount (dehydration amount) in the water supply at a very low water level in the step, and the water level corresponding to the washing amount detected in the step After deciding and watering the determined water level, the pulsator is rotated forward and reverse to release the unbalance, and if the unbalance is released in the above step, dehydration is completed until dehydration is completed.

Figure 3 is a flow chart for the dehydration method of the washing machine of the present invention, the dehydration step of dehydration while rotating the motor in one direction at a high speed by selecting only the dehydration of a series of washing administration in the state to put the laundry to be dewatered initially in the washing tank ( 30), an unbalance determination step 31 for determining whether an unbalance has occurred with a safety switch during dehydration in the dehydration step 30, and if debalance does not occur in the unbalance determination step 31, dehydration is continued. Dehydration progress step 32 to stop, and if the unbalance occurs in the unbalance determination step 31, dehydration stop step 33 to stop the dehydration by stopping the motor, and if dehydration stops in the dehydration stop step 33 Water supply step (34) for controlling the drainage drive water to the washing tank at a very low water level, and acts on the motor in a state of supplying water to the very low water level in the water supply step 34 A washing amount detection step 35 for detecting a washing amount (dehydration amount) under load, a level determining step 36 for determining a water level corresponding to the washing amount detected in the washing amount detecting step 35, and the water level determining step ( After the water supply at the water level determined in 36), the pulsator is rotated forward and backward to release the unbalance, and the debalance is released while the debalance is released in the unbalance release step 37. Dehydration is to complete the determination step 38.

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

First, power is supplied to the washing machine, and after washing the relatively light type of laundry (handkerchief, socks, underwear), etc., the laundry is put in the washing tank 2 so as to dehydrate the washing machine only, and the driving signal input unit When only the dehydration is selected, the microcomputer (b) is controlled by a predetermined program in the microcomputer (b) by the input dehydration administrative signal, and outputs the controlled signal to each drive unit to perform dehydration. In other words, the microcomputer (b) goes to the dehydration step (30) to control the motor driving part (e) to rotate the motor (5) in one direction at high speed to rotate the washing tank (2) at high speed while rotating the laundry in the washing tank (2) with a centrifugal force In this process of dehydration, the microcomputer (b) goes to the unbalance determination step 31 and freezes through a safety switch (not shown). If it is determined that the balance has occurred, if the unbalance is not generated at this time, the microcomputer (b) proceeds to the dehydration progress step 32 to continue the dehydration, while in the unbalance determination step 31 If unbalance has occurred, the microcomputer (b) goes to the dehydration stop step 33 to control the motor driving part (e) to stop the motor 5 to stop the dehydration while stopping the washing tank 2.

In the state where dehydration is stopped as described above, the microcomputer (b) goes to the water supply step 34 to release the unbalanced water and controls the water supply and drainage drive unit C to supply water to the washing tank 2 at a very low level, and then to detect the amount of washing. Go to step 35 to control the motor drive (e) to rotate the pulsator (3) forward and reverse to sense the amount of washing in the load state acting on the motor (5) according to the action on the pulsator (3) When the washing amount is detected, the microcomputer (b) goes to the water level determining step 36 to determine the water level according to the detected washing amount.

When the water level according to the washing amount is determined as described above, the microcomputer (b) goes to the unbalance release step 37 and controls the motor driving part e to set the pulsator 3 through the motor 5 at a predetermined time and number of times. To reverse the rotation, release the unbalance, and then go to the dehydration completion determination step 38 to determine whether the dehydration is completed. If the dehydration is not completed, the microcomputer (b) dehydration progress step ( Go to 32) to proceed with dehydration, while if the dehydration is completed, the dehydration is terminated.

As described above, in the present invention, when dehydration is selected only in a series of laundry administrations for a relatively light type of laundry, when water is unbalanced during dehydration, water is supplied to a very low level to detect a washing amount, that is, dehydration amount By dehydration while releasing the unbalance after supplying water according to the dehydration amount, it is possible to provide an effect of dehydration while preventing unnecessary waste of water and time when the unbalance occurs.
