Description

How to set the balance on time of the washing machine

The present invention relates to a method for setting a balance on time setting of a washing machine, and in particular, an initial balance on time for determining whether to enter a re-administration according to an unbalanced state occurring when a washing machine is dehydrated can be variably operated according to a state of a washing machine. By doing so, the efficient operation of the washing machine can be expected.

The washing machine is installed in the water storage tank 32 accommodating the washing tank 33 which is rotated in the main body 30 as shown in FIG. 1, and is installed at the lower center of the washing tank 33 to generate water flow using the power of a motor to wash the laundry. It includes a pulsator 34, a deceleration unit 36 for transmitting the power of the motor 35 to the washing tank 33 and the pulsator 34 to reduce the transmission, and the motor 35 and the like. .

In addition, the system circuit related to the driving of the washing machine in the above washing machine is shown in FIG. 2.

Here, the microcomputer 21 of the system control, the memory 20 storing the procedure data of the respective strokes for the system operation, the sensing data of the detectors and the programs, and the display and the operation completion of the various operations, etc. Safety alarm for shutting off the system power during unbalanced operation of the display alarm unit 24, the relay drive unit 23, the key input unit 22, the load drive unit 25, and the washing tank, which perform an alarm function to be notified. The part 31 is included.

The system includes a water level detector 26, a load detector 27, a temperature detector 28, an unbalance detector 29, an interrupter 32, and the like for various control operations of the microcomputer 21. It is provided.

In the conventional washing machine, when the laundry is not evenly placed in the washing tank during the dehydration operation of the system, and the reservoir is abnormally vibrated, the system performs an automatic unbalance control function according to the open time of the safety switch unit 31. .

At this time, if the microcomputer 21 checks whether the safety switch unit 31 momentarily cuts off the dehydration circuit after the draining and dehydrating step, and checks if the operation is continued three times or more and if it continues three times or more Unbalance bad alarm (UE) is displayed externally.

If the instantaneous blocking is not in the above, the dehydration operation is performed, and again the safety switch unit 31 checks whether the instantaneous blocking of the dehydration circuit, and if the instantaneous blocking goes to the step of determining whether the operation is three or more times.

In addition, when the operation is not continued three times, the water is supplied, the rinsing operation is performed for 2 minutes, and then the draining step is performed.

In addition, when the bad alarm as described above to open the door to release the tangling and gathering of the laundry, causing the unsafe switch phenomenon, and then close the door and dehydration will reduce the unbalance phenomenon.

In addition, as described above, the unsafe switch judgment is closely related to the on / off time of the safety switch unit 31. The unbalance determination affects the driving voltage, the belt tension, and the switch deviation of the safety switch unit 31. , Washing machine aging, motor torque.

On the other hand, in the prior art, it is possible to perform the safety measures and recovery operations of the system for the unbalanced state of the washing tank, the prior art related to this operation is disclosed in Korean Patent Publication No. 1714 (Notification No. 96-1289), Patent Publication No. 1897 (Publication No. 96-23403) and the like are known.

The former technique suggests a means for detecting an unbalanced signal in the initial dehydration stage to stop the system driving motor or to proceed the main dehydration according to the unbalanced signal detection state. The latter technique provides a rinse stroke. Since the unbalanced state is detected when the dehydration operation is performed, a means of eliminating the unbalanced state is provided by supplying a constant rotational water flow.

However, in the prior art as described above, due to various factors affecting the unbalance determination as described above, there may be a washing machine in which re-rinsing occurs well and a washing machine in which less re-rinsing occurs. Since the on-time of the safety switch unit 31 is driven by the system, but should not be changed despite the above factors depending on the system use environment, there was a problem in efficiently operating such a system.

For example, the microcomputer 21 has an on time of the safety switch 31 to determine an unbalanced state to determine whether to perform the next stroke or to stop the system operation. Because they couldn't lengthen or shorten, side effects such as unnecessarily shutting down the system even though they did not overwhelm the system equipment were inevitable.

An object of the present invention is to actively avoid the phenomenon that the system microcomputer performs more than necessary control operation by allowing the user to arbitrarily set and use the balance on time of the washing tank in such a washing machine system to improve the above problems It is designed to increase the efficiency of system operation.

In particular, the present invention provides a process of operating the on-time setting indicator when there is a balance on-time setting key input in the system so as to realize the object of the above example, and then setting the balance on-time with the time-up key or time-down key and storing it in the system memory. The balance on-time setting processing method of the washing machine performed by the balance on-time setting program which has a balance on-time setting program, and the balance on-time execution program of the process of performing a balance dehydration operation according to the balance on-time setting program registered by this balance on-time setting program is characterized by the above-mentioned. It is.

200. Balance On Time Execution Program

That is, FIG. 4A illustrates an embodiment of the balance on time setting program 100 to implement the balance on time setting processing method of the present invention.

Here, the system checks whether there is a balance on time setting key input, and if there is a balance on time setting key input, operates the on time setting indicator (steps 101 and 102), and checks whether the user presses the time up key while looking at the on time setting indicator. If the time up key is pressed, the balance on time time is increased by 1 and the set time data is stored in the memory when the time up key is turned off (steps 103 to 106), and the time down key is pressed instead of pressing the time up key. Reducing the balance on time by one and storing the time data set at the time of down key off in the memory (steps 107 to 109, 106) and the like.

4B shows a balance on time execution program 200 for operating the system in accordance with the on time registered with the balance on time setting program 100.

In this case, the step of checking whether the drainage end is at the end of the drainage is checked (steps 201, 202), and if the balance is the on-time mode, the initial balance value is extracted to recognize the unbalanced state according to this value, and the balance is at the balance state. Dehydration is performed (steps 203 and 204).

In the system, the select key is a power button switch 1, a reserve button switch 2, a cancel button switch 3, a water supply button switch 4, a washing button switch 5, a rinse button switch 6, a temperature button switch 7 installed in the key input unit 22. , Level switch 8, stroke button switch 9, start / hold button switch 10 were set by a combination thereof.

In the present invention, the system user adjusts the unbalance on time in the system according to various factors caused by the washing machine itself such as driving voltage, belt tension, switch deviation of the safety switch unit 31, aging of the washing machine, and torque of the motor. It can be used.

For example, according to the unbalanced state of the washing machine, the on time of the safety switch is switched to the operation off state for 3 seconds from the operation on state for 6 seconds, as shown in FIG. In the process, the microcomputer 21 operates according to the unbalanced on-time setting state of the user when determining whether to stop or continue the system operation.

At this time, the user determines the state of the washing machine and sets the unbalance on time of the safety switch unit 31.

When the user sets the unbalance on time, when the balance time setting key is pressed through the key input unit, the microcomputer 21 recognizes this and displays the number of the indicator in the up / down mode.

Then, the user can select the power button switch 1, reserve button switch 2, cancel button switch 3, feed button switch 4, washing button switch 5, rinse button switch 6, temperature button switch 7, level switch 8, stroke button switch 9, When the button key defined by the combination of the start / hold button switches 10 is pressed, the number operates in the up or down mode to set an unbalance on time of an arbitrary second.

For example, when the user sets the unbalanced on time to 3 seconds, press 2 and 4 simultaneously.

In this case, the microcomputer 21 recognizes this as an up mode and increases the number from 0 to 9 through the indicator. Thus, when the user turns off 2, 4, the number stops at the value 3. will be.

Likewise, if the user presses 2,5 simultaneously, the indicator recognizes the down mode, and the indicator number decreases from the current value number from 0 to 9. If the user turns off 2,5, the number stops.

In addition, the up / down mode can be replaced by a single button key without pressing two buttons.

Meanwhile, the balance on time setting operation as described above is performed by the microcomputer 21 together with the balance on time setting program 100 as shown in FIG. 4A, which checks whether a balance on time setting key is input from the system and balance on time. When there is a time setting key input, the on-time setting indicator is activated.If the user presses the time-up key while checking the on-time setting indicator and presses the time-up key, the balance on-time time is increased by 1 and the time-up key is off. The set time data is stored in the memory (steps 101 to 106).

If there is a time down key press instead of the time up key press, the balance on time is decreased by 1 and the time data set at the down key off time is stored in the memory (steps 107 to 109 and 106).

In addition, when the balance on time setting operation as described above is completed, the washing machine performs the washing machine operation according to the balance on time execution program 200 as shown in FIG. 4B.

In this case, it checks whether it is the end of drainage or not, if it is the end of drainage, checks whether it is in balance on time mode; (Steps 201 to 204).

The present invention is to enable the use of the device efficiently without side effects, such as stopping the washing machine unnecessarily frequently by allowing the balance on time that occurs during the dehydration process in the washing machine can be changed arbitrarily according to various conditions of the washing machine.
