    How to set the unbalance cycle of the washing machine
    The present invention relates to a method for setting an unbalance cycle of a washing machine, and in particular, in detecting an unbalance of a washing tank caused by twisting of a laundry during dehydration operation, by resetting the unbalance detection cycle automatically according to the washing capacity of the washing machine. The present invention relates to a method for setting an unbalance cycle of a washing machine, which enables dehydration while detecting unbalance with an unbalance detection cycle.
    In general, the unbalance detection of the washing machine is to be detected by the number of operation in the safety switch mounted on the outer top of the water tank of the washing machine. That is, the unbalance detection of the safety switch detects the operation of the first (7 seconds) safety switch by performing the washing tank four times for a predetermined time (4 seconds on, 3 seconds off) when the balance is dewatered after draining in a series of washing strokes. And then detect the presence or absence of the safety switch for the second (7 seconds) and detect the unbalance by the number of operation of the detected safety switch. To detect the unbalance, drive the motor for at least 4 seconds and then the next safety switch. You must wait 7 seconds for the operating time to detect unbalance.
    As described above, in the prior art, when the dehydration is performed, the unbalance is detected and judged by the operation state of the safety switch, that is, the water tank, by pressing the safety switch in the balance dewatering stroke. It is set to detect by one operation of safety switch.
    However, the unbalance detection cycle in the washing machine should vary according to the washing capacity. That is, in the case of a washing machine with a large washing capacity, the washing load is easily generated due to the large amount of washing, whereas in the washing machine with a small washing capacity, the washing amount is small. As a result, unbalance does not occur easily.
    Nevertheless, in the related art, since the unbalance detection cycle is set uniformly regardless of the washing capacity, the unbalance is detected again by a predetermined cycle when the debalance is removed again after the unbalance is released after the unbalance is generated. There is a problem in that the time period for detecting the relatively long, so that the overall dehydration time is long, it has a cumbersome problem to set the operating cycle and the operating clearance of the safety switch in accordance with the washing capacity of the washing machine.
    An object of the present invention by detecting the time according to the number of operation of the safety switch to detect the occurrence of unbalance during dehydration and by resetting the operating cycle of the safety switch to detect the unbalance occurs in this set period, when dehydration regardless of the laundry capacity As well as to accurately detect the unbalance, to solve the hassle of having to set the operating play of the safety switch in accordance with the washing capacity.
    In order to achieve the above object, the present invention provides a method for performing balanced dewatering in a state where a series of washing or rinsing strokes are completed and draining is completed, determining whether the balance dewatering is completed in the step, and balancing in the step. If the dehydration is not completed, the step of detecting the operation of the safety switch, if the operation of the safety switch is not detected in the above step proceeds to balance dehydration, if the operation of the safety switch is detected in this step, the operation count is added Storing the sensing time; determining whether the safety switch has been operated at a predetermined number of times during the balance dewatering step; and in this step, the safety switch has been set at a predetermined number of times. If it is not detected, continue to balance dehydration, and in this step the safety switch If the alarm is detected, the error alarm and detection is calculated and reset the operation cycle of the safety switch for the operation time and the number of the stored safety switch, and the step of re-rinsing with the reset operation cycle of the safety switch in the step Characterized in that it comprises the step of releasing the unbalance.

The safety switch operation frequency determination step of judging whether the operation frequency of the safety switch has reached the predetermined operation number arbitrarily set in the state of detecting and storing the operation time in the operation step 34 and the operation time detection storage step 34. (35), and if the operation number of the safety switch detected in the safety switch operation number determination step 35 does not reach a predetermined operation number (3 times) set arbitrarily, balance destal is continuously performed, while safety When the operation frequency of the switch reaches a predetermined number of operation times (3 times), an error alarm is issued and the average operation period is calculated and reset according to the stored time detected according to the operation frequency of the safety switch. 36), and when the operation cycle of the safety switch is reset in the operation cycle reset step 36, re-rinsing is performed on the unbalance generated to perform unbalance. It is to be made to the unbalance release step 37 to release.
    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 to be washed is initialized in the state where the microcomputer (b) of the washing machine is initialized. Then, the driving signal for the series of washing administrations to be washed through the driving signal input unit is inputted to the microcomputer. If input to (b), the microcomputer (b) determines the water level for the laundry by a predetermined program, and controls the water supply and drainage drive unit (c) to supply water to the determined water level, and the water supply level is the water level. While sensing through the sensing unit (d), water is supplied to the determined water level and completed.
    When the water supply is completed as described above, the microcomputer (b) controls the motor driving part (e) to form the washing water flow while washing the pulsator forward and reverse, and proceeds to washing, but washes until a predetermined washing time is completed. After the washing is completed, the microcomputer (b) proceeds to complete the rinse a predetermined number of times set at random.
    When the washing or rinsing is completed, the microcomputer (b) goes to the balance dewatering step 30 to control the motor driving part (e) to proceed with the balance dewater while rotating the washing tank in one direction at high speed, and the balance dewatering proceeds. While the microcomputer (b) goes to the balance dehydration completion determination step 31, it is determined whether the balance balance in progress is completed. At this time, if the balance balance is completed, the main dehydration proceeds, while the balance dehydration is not completed. If not, the microcomputer (b) goes to the safety switch operation judgment step 32 of the water tank 1 caused by the unbalance of the washing tank caused by the twist of the laundry during the washing or rinsing through the safety switch unit (bar) It is determined whether the switch lever 4 of the safety switch 5 mounted on the outer upper side is activated, and the safety switch 5 is detected. If the switch lever 4 is not operated, the balance dewatering step 30 goes to the balance dewatering process. However, if the switch lever 4 of the safety switch 5 is operated, the number of operation counts in the microcomputer (b). Go to step 33 and add and store the number of operation of the safety switch 5, and then go to the operating time sensing storage step 34 to take the switch lever 4 of the safety switch 5 to turn on in the off state It detects the time and stores the detected time.
    As described above, when the operation time of the safety switch is sensed and stored, the microcomputer (b) goes to the safety switch operation count determination step 35, and the operation number of the detected safety switch 5 is arbitrarily set a predetermined number of times (three times). In this case, if the operation number of the safety switch 5 is not set to a predetermined number of times (3 times), go to the balance dewatering step 30 and proceed with the balance dewatering. In this case, the microcomputer (b) goes to the operation cycle reset step 36 and unbalances, when the number of times of the safety switch reaches a predetermined number of times of operation is set. In addition to alarming that the occurrence of the error, the detected time according to the operation of the safety switch is divided by the number of operation to calculate the average operating time to the calculated time The operating cycle of the safety switch will be reset.
    When the operation cycle of the safety switch for the unbalance detection is set as described above, the microcomputer (b) goes to the unbalance release step 37 to control the water supply and drainage drive unit (c) to supply water to a predetermined level arbitrarily set in the washing tank. After controlling the motor driving part (e), the pulsator is rotated forward and reverse, and the rinsing is released for an arbitrarily set time (2 minutes). After releasing the laundry, the water is drained and then goes back to the balance stapling water (30). While controlling and proceeding until the balance dewatering is completed while rotating the washing tank in one direction at high speed, the microcomputer (b) goes to the safety switch operation judgment step 32 to determine whether the safety switch is operating, but at this time, the operation according to the presence of the operation. The cycle is to balance the dehydration while determining the operation by the reset operation cycle.
    As described above, the present invention detects the unbalance occurrence at this set period by resetting the operation cycle of the safety switch after detecting and storing the time according to the operation frequency of the safety switch that detects the unbalance occurrence during dehydration, thereby relating to the washing capacity. Without dehydration can accurately detect the unbalance, and also provides a convenient advantage that does not need to set the operating play of the safety switch in accordance with the washing capacity.
