Method for Controlling Course of Washing Machine

The present invention relates to a washing machine, and more particularly, to a stroke control method of a washing machine for making a user's washing machine more convenient.

In general, a washing machine is a device that removes contaminants from contaminated laundry through washing, rinsing, and dehydration according to a predetermined algorithm, and is fully automatic using horizontal rotation of a rotary blade, outer tank, or inner tank (washing tank / dehydrating tank). A washing machine or a drum washing machine using vertical rotation of the drum can be broadly classified.

Such a washing machine has been developed for a variety of washing courses, functions, etc. in order to respond to a variety of needs of the user and applied to the actual product.

As shown in FIG. 1, the washing machine according to the related art includes a key input unit 10 for a user to input various washing-related operation commands, and a washing wing 20 for directly transmitting rotational force to the washing water and the laundry cloth. And an inner tub 30 and an outer tub 40 forming a washing tub into which the washing water and the washing cloth are introduced, and a motor for directly or indirectly rotating the washing blade 20, the inner tub 30, or the outer tub 40. 50, a water supply valve 60 for introducing the washing water into the washing tank, a drain valve 70 for draining the washing water, and a display unit for displaying an operation state or function of the washing machine, etc. (Not shown) and load driving of the motor 50, the water supply valve 60, the drain valve 70, and the like to perform a washing operation corresponding to a user's operation command input through the key input unit 10. Control and display of the operation status or function Such that the system is configured to include a microcomputer (not shown) for controlling the display portion.

In this case, the display unit is provided with a light-emitting diode (LED) and a ROM for storing a non-changeable laundry related program in the system microcomputer.

Referring to the operation of the washing machine according to the prior art configured as described above are as follows.

First, the user turns on the power of the washing machine and inputs a washing instruction for washing, rinsing, and dehydrating through the key input unit 10, and loads laundry into the washing tank. Subsequently, the system microcomputer recognizes the washing instruction and reads the washing program from the internal ROM and drives various loads such as the motor 50, the water supply valve 60, and the drain valve 70 based on the washing program. The washing, rinsing and dehydration are performed according to the washing instruction input.

At this time, in order to prevent the imbalance during the dehydration stroke and to smooth dehydration, a foaming stroke is performed to evenly spread the laundry cloth before a predetermined time before the washing administration ends. The inflated stroke is performed after draining a predetermined amount of washing water through the drain valve 70 before the end of the washing stroke. During the inflated stroke, the on time of the motor 50 is longer than the washing stroke. The predetermined time is short.

The display unit displays a current washing progress state under the control of the system microcomputer.

Referring to the stroke control method of the washing machine according to the prior art operating as described above are as follows.

As shown in FIG. 2, a washing stroke is performed among washing, rinsing, and dehydrating stroke commands inputted through the key input unit 10 from a user (S10). It is determined whether time is reached (S11).

As a result of the determination (S11), when the remaining time of the washing stroke reaches the first set time, the washing stroke is stopped (S12) and drained through the drain valve 70 (S13).

Then, it is determined whether the current water level A of the washing water reaches a predetermined set water level A 'due to the drainage (S14). The determination result (S14) the current water level A is the set water level A'. In step S15, the inflating stroke is performed during the first set time.

Subsequently, it is determined whether the first set time has elapsed (S16). When the first set time has elapsed, the determination result (S16) is completed. Perform (S17, S18)

On the other hand, if the determination result (S14), the current water level (A) does not reach the set water level (A '), it is determined whether the drainage progress time has passed the second preset time (S19).

Then, the determination result (S19) generates a warning sound to inform the user of the drain error if the drainage progress time has passed the second set time (S20).

As described above, the administrative control method of the washing machine according to the related art is that when the user sets only the washing stroke alone, the users usually think that the drainage will not be made, so that the drain valve is placed without the drainage being considered. There is a problem that the inflated stroke is not performed and a drainage error occurs, resulting in inconvenience in use.

The present invention has been made to solve the above problems, an object of the present invention is to provide an administrative control method of the washing machine to solve the inconvenience in use during the laundry administration.

In accordance with another aspect of the present invention, there is provided a stroke control method of a washing machine according to the present invention, in which a washing machine having a key input unit comprises a user setting a washing, rinsing, and dehydrating stroke command through the key input unit. And performing a washing operation according to the washing operation, determining whether only the washing is set in the administrative command when the remaining time of the washing administration reaches a preset first setting time, and, if only the washing is set, the first washing time. It is characterized by including the step of performing the inflated stroke during the set time.

Hereinafter, the stroke control method of the washing machine according to the present invention with reference to the accompanying drawings.

In the present invention, since the configuration of the washing machine is the same as the above-described conventional description, the detailed description thereof will be omitted, but if only the washing administration is set from the user, the system micom drains the inflated stroke before a predetermined time before the washing administration ends. Controls to execute without doing.

3 is a flow chart showing the stroke control method of the washing machine according to the present invention. Referring to this, the stroke control method of the washing machine according to the present invention will be described as follows.

As shown, first, a washing stroke is performed according to an administrative command input through the key input unit 10 from a user (S30), and it is determined whether the remaining time of the washing stroke is a preset first setting time (S31). .

As a result of the determination (S31), when the remaining time of the washing stroke reaches the first set time, it is determined whether only the washing stroke is set among washing, rinsing, and dehydrating strokes from the user (S32).

In addition, if only the washing stroke is set as the determination result (S32), the inflation stroke is performed (S33), and it is determined whether the first set time has elapsed (S34). When the time elapses, the inflation stroke is completed, that is, the washing administration is completed.

On the other hand, the determination result (S32) if only the washing stroke is set, that is, if the rinsing stroke or dehydration stroke is set with the washing stroke (S35) stops the washing stroke (S35) and drains through the drain valve 70 It performs (S36).

Then, it is determined whether the current water level (A) of the washing water reaches a predetermined set water level (A ') due to the drainage (S37). The determination result (S37), and the current water level (A) is the set water level (A). If it does not reach '), it is determined whether the drainage proceeding time passes a preset second set time (S38).

Subsequently, if the current water level A reaches the set water level A 'or the drainage progress time passes the second set time, the determination result (S37 or S38) is performed (S39). .

It is determined whether the inflation stroke execution time passes the first set time (S40), and when the first set time passes, the rinsing stroke and the dehydration stroke are performed (S41, S42).

Therefore, in performing the inflated stroke, if the user sets only the washing stroke without setting the rinsing and dehydrating stroke, the inflating stroke is performed without draining a predetermined time before the end of the washing stroke.

The stroke control method of the washing machine according to the present invention described above has the effect of improving the reliability of the washing machine by controlling to perform the inflated stroke without performing drainage when the washing stroke alone.
