How to check the life of parts of the washing machine

The present invention relates to a method for checking the life of a part of a washing machine, and more particularly, to a method for checking the life of a part of a washing machine, which can be used while checking the life of a washing machine (replacement time) by the frequency of use when the washing machine is used after purchase.

In general, the parts life of a washing machine is typically checked based on how long (years of use) the washing machine is used.

Therefore, when a washing machine breaks down while you purchase and use a washing machine and asks for repair, the repairer first checks the purchase date of the washing machine and repairs it, because the warranty period is given after the sale of the washing machine. Therefore, if a failure occurs within this period, the failure of the generated parts is mainly determined to be a defect or an abnormality in the assembly process, but the repair is performed, but if the washing machine is broken after the warranty warranty period has elapsed Since the repairman checks the life of parts of the washing machine based on the purchase year of the washing machine, for example, if the user breaks down the washing machine with a low frequency of use after the purchase of the washing machine, Convert the parts according to the years of use of the washing machine Judge the problem and repair it.

However, the washing machine has an inherent lifespan for various parts, but the user cannot know at least how long the lifespan is for the malfunctioning parts, so that the washing machine cannot cope with a failure occurring during washing.

Therefore, when a failure occurs during the use of the washing machine not only ruin the laundry, but also has a problem that the user is troublesome and various inconveniences due to the failure.

An object of the present invention is to store the life of the parts for the main parts of the washing machine, the life of the parts is stored on the basis of the frequency of use, then check the frequency of use of the parts, inform the replacement time of the parts in advance By repairing or replacing parts that may occur in the middle, the product can be washed after repairing it in advance, thus preventing troubles occurring during washing, and ruining the laundry caused by the problem or eliminating inconvenience and inconvenience. I want to be.

In order to realize the above object, the present invention provides a method of counting the frequency of use of a washing machine in a state in which the frequency of use of the washing machine is set for the life of the main parts of the washing machine, and the frequency of use counted in the step is based on the life of the parts. Determining whether the set frequency of use has been reached, and if the frequency of use has not reached the set frequency of use, storing the frequency of use so far, and the frequency of use in the step. When the set frequency of use is reached, a step of alerting when the parts are replaced is performed.

In the laundry administration input judging step 30 to determine the operation, and if the operation signal for the laundry administration is not input in the laundry administration input judging step 30, the standby state is maintained, while the laundry administration input for the series of laundry administrations is performed. When a signal is input, the washing administration execution step 31 for performing a series of washing administrations, the washing administration completion determination step 32 for determining whether the washing administration performed in the washing administration execution step 31 is completed, and the When the washing administration is completed in the washing administration completion step 32, the frequency count count step 33 to count the count of the frequency of use of the washing machine, and the frequency count count stage A frequency counting step 34 for judging whether the frequency counted count added in step 33 reaches a frequency set arbitrarily set according to the part life, and the counting count counted in the frequency counting step 34; If the frequency of use has not reached the set frequency of use, the frequency of use counting step 35 for storing the frequency of use counted up to the present, and the frequency of use counted in the frequency count determination step 34 When the number of times reaches the set frequency of use, it is made to the parts bridge environmental protection step 36 to alert the replacement time of the parts.

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

First, when a washing machine is purchased, the seller uses a predetermined key switch (not shown) through the operation signal input unit to indicate the frequency of use of the washing machine and to indicate the lifespan of the washing machine. B) The microcomputer (b) stores the frequency of use of the input component in the memory unit by a predetermined program.

As described above, in the state where the frequency of use of each of the main parts of the washing machine is stored in the memory unit, the microcomputer (b) goes to the washing administration input determining step 30 and through the operation signal input unit A. It is determined whether a signal for washing, rinsing, and dehydration operation, which is a series of washing administrations, is input. If no signal for the series of washing administrations is input from the operation signal input unit a, the standby state is maintained. On the other hand, when the operation signal for the series of washing administration is input from the driving signal input unit (a), the microcomputer (b) goes to the washing administration execution step 31 and controls the water supply and drainage driving unit (C). Proceed with water supply, while the water level is detected while the water level is supplied through the water level sensor (6) of the water level detection unit (D).

Subsequently, when water supply is completed, the motor driving part (e) is controlled to control the pulsator 3 through the motor 5 and the gear part 4, and the reverse and rotation of the pulsator 3 is controlled by the pump driving part (bar). Washing is performed while pumping and circulating water, and when the washing is completed, the rinsing water is supplied again and the motor driving part (e) is controlled to fix the pulsator 3 through the motor 5 and the gear part 4. , Reverse rotation and the pump driving unit (bar) to control the pumping, rinsing while circulating the washing water to the pump (8), the rinsing proceeds to a predetermined number of times, and the rinsing is completed when the rinsing is completed .

While performing a series of washing administration as described above, go to the washing administration completion determination step 32 in the microcomputer (b) to determine whether the series of washing administration is completed, and if the series of washing administration is completed In the microcomputer (b), go to the frequency count count step 33, and add the count of the number of times the washing cycle is completed, and then go to the frequency count step 34 to control the memory unit (g) A randomly set frequency of use for the life of the component is read and it is determined whether the read frequency of use is consistent with the counted frequency of use. In this case, the counted frequency of use is determined. If the randomly set frequency of use has not been reached, the microcomputer (b) goes to the frequency of storing frequency of use (35) step and counts And stores the frequency number, and waits for the next washing cycle.

However, if the counted frequency of use has reached the arbitrarily set frequency of use, the microcomputer (b) determines that it is time to replace a part of the washing machine currently in use, and goes to the part bridge environment preservation step 36. By controlling the control unit to warn the user of the replacement time in advance, the user can replace the parts in advance and then wash.

At this time, since the replacement time for the parts is somewhat different depending on the characteristics of the parts, the frequency of use is different and the replacement time is also different. Therefore, the replacement time is arbitrarily set according to the parts, and for each part, respectively. It is desirable to check the frequency of use and to replace it.

As described above, the present invention sets the frequency of use for the life of the main parts of the washing machine, and counts the frequency of use every time a series of washing operations is performed, and the counted frequency of use is added to the parts. It is judged whether the set frequency of use has been reached according to the service life, and if the counted frequency of use has reached the set frequency of use, the replacement time is alerted to notify the replacement time in advance so that the replacement time can be notified. Since it is possible to wash after repairing or replacing parts that may occur in advance, it is possible to prevent the failures occurring during the washing in advance, so as not to ruin the laundry caused by the failure or troublesome and inconvenience It will provide a possible effect.
