Description

Separate washing control method of automatic washing machine

The present invention relates to a detachable washing control method for a fully automatic washing machine, and more particularly, to a detachable washing control method for a fully automatic washing machine,

1 and 2, a conventional automatic washing machine is provided with a washing tub 2 rotatably installed inside an outer tub 10 in a main body 9, and at the lower center of the washing tub 2, And the washing shafts 12 and the washing shafts 13 of the clutch 11 installed at the center of the bottom of the outer tub 10 penetrate through the washing tub 2 and the washing tub 3, A motor pulley 16 and a clutch pulley 17 are installed on the motor 15 and the clutch 11 which are mounted on the bottom surface of the outer tank 10 and driven by a control signal of the microcomputer 14, And a V-belt 18 is wound around the motor pulley 16 and the clutch pulley 17 to transmit power.

A water supply valve 19 for supplying wash water to the inside of the outer tank 10 is provided at one side of the upper portion of the main body 9 by a control signal of the microcomputer 14, A drain valve 21 for discharging washing water in the outer tub 10 to the outside of the main body 1 through a drainage hose 20 is provided at a lower side of the washing tub 2 in accordance with a control signal of the microcomputer 14, And a detachable laundry net 1 to be detached and detached is detachably installed inside.

The conventional fully automatic washing machine includes a voltage detecting means 22 for outputting a signal corresponding to the discharged amount, and a remaining amount determining means 22 for comparing the discharged amount with a reference value for discriminating the discharged amount by receiving a signal corresponding to the discharged amount, (24) for inputting a signal to the water supply valve (19) so as to feed back various signals to the quantity determination means (23) and to set a water level suitable for the amount of water discharged by the water supply control means If it is determined that the water level has reached the predetermined water level, the water level is continuously supplied to the process control means 24 to stop water supply if the water level has reached the set water level And a water level detecting means 25 for inputting a signal.

Accordingly, when the user starts washing and arbitrarily sets the water level first, the washing water is determined after completion of the water supply to the set water level, and the amount of laundry after the laundry is detected and the water level selected by the first user is determined and compared Here, the water level set by the user is not changed. When the washing water is determined, the washing cycle is performed, and when the washing cycle is completed, the next washing cycle is executed.

On the other hand, in order to output a signal corresponding to the conventional discharging amount, a voltage detecting part 22a using a voltage waveform as shown in Fig. 3 is used, or a voltage detecting part 22a using a light receiving and light emitting element 26 5 and 6, the polarity (N pole or S pole) of the magnet 28 is used as a hall sensor 29 as a counter The Hall sensor 29 is used in a variety of ways, including a Hall sensor, which will be described below with reference to FIGS. 5 and 6. FIG.

That is, a magnet 28 in which N poles and S poles are alternately arranged by a predetermined number in the vicinity of the rotation axis around the periphery of the motor 15, and a hall sensor 29 provided at one side of the magnet 28, The Hall sensor 29 counts the number of pulses in accordance with the change in polarity per unit time generated when the backlight is turned off, and the principle of the determination of the detected amount is shown in Fig.

That is, when the number of pulses is small, the amount of pulses per unit time is large. When the amount of pulses is large, the amount of pulses per unit time is relatively small. Based on this principle, And the water supply amount, the washing time, the number of rinsing times, and the dewatering time are set according to the judgment.

However, in such a conventional automatic washing machine, rough laundry such as jeans, which requires a lot of impact in the lower portion of the washing tub 2 and has a relatively high degree of dirt, is inserted into the washing tub 2, It is necessary to put a laundry such as soft lingerie or the like which tends to damage the cloth even in a small impact on the top of the net 1 so as to press the course suitable for carrying out the separate washing. If you press the button that you want to detach, you will run a course that is suitable for detached washing, although it is not the case that you do not actually perform separate washing.

As described above, when the button for desiring to separate laundry is pressed while the separated laundry net 1 is not attached during the separate washing, the separated laundry course is executed without determining whether the separated laundry net 1 is mounted, And the conventional laundry amount determining means 23 has a problem in that it is difficult to judge whether the separated laundry net 1 is mounted or not.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a washing machine, The present invention has been made to solve the above problems, and it is an object of the present invention to provide a separate washing and controlling method of a fully automatic washing machine capable of accurately detecting whether or not a separate washing net is installed in the inside of a washing tub and whether or not laundry is put into the top of the separated washing net.

According to another aspect of the present invention, there is provided a method of controlling a washing machine, the method comprising: determining whether a user selects a separate washing course; A step of detecting only the lower end of the separated laundry net by rotating only the laundry wings when the total laundry load is detected; calculating a load amount of the laundry based on the load of the laundry and the amount of the laundry detected at the lower end of the separated laundry net Determining whether or not the separated laundry environment is valid according to a value obtained by dividing the laundry in the washing laundry environment; and performing a normal separation washing cycle in the case of the separate laundry environment, A separate washing control method of the automatic washing machine is provided.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 7 and 8.

FIG. 7 is a longitudinal sectional view showing a fully automatic washing machine according to the present invention, and FIG. 8 is a flowchart showing an operation state of the present invention. The external structure of the present invention is similar to the conventional art, A method of determining whether the laundry washing course button is pushed by inserting a pouch at the top of the washing machine 1 and a stroke control method therefor will be described.

Hereinafter, the method for calculating the method for determining whether or not the separated laundry net (1) and the top of the separated laundry net (1) are provided is as follows.

When the cloth is put on the upper and lower ends of the separate washing net 1 and the separate washing net 1, the washing tub 2 and the washing tub 3 are first rotated in the direction of dewatering. At this time, Should be entered.

1. Washing tank + detachable washing net + washing blade: rotating

- Load determination value by the weight of the washing machine during rotation of the washing machine A + Load determination value by the weight of the washing net B + Load determination value by the rotation of the washing blade C + Load determination value by the peripheral device (during power transmission) D The total load value is an integer (α)

2. Washing tank + Separation Washing net + Separation Washing net on top, bottom laundry + Washing blade: Rotation

- Load variable value after loading of laundry (β) - Constant (α) = Total load of washing (Load on separating washing net,

(Χkg) of laundry is inputted into the inside of the washing tub, the washing laundry is rotated only after determining the total washing amount inputted into the washing tub. At this time, the following values should be inputted.

3. That is, the load value = constant (? ') When rotating the laundry blade only in a state where the washing tub is fixed should be stored in the quantity determination table.

4. And if you only rotate the washing wing with the washing tub fixed, you can judge the laundry at the bottom of the washing net.

(- ') (-) () () () () () () () ()

When the laundry load value γ '= + value at the bottom of the separated laundry net is found as a result of the above-mentioned total laundry load value γ (χkg), it is determined that there is a laundry at the top of the separated laundry net, If the total load value γ of laundry laid out by rotating the washing tub 2 and the washing blade 3 together with the load value γ 'obtained by rotating only the washing blade 3 are similar, And the alarm sound is notified.

Hereinafter, the process will be described with reference to the flowchart of FIG.

First, whether or not the user has selected the separate washing course is judged by the separate washing course judging unit 4. When it is judged that the user has selected the separate washing course, the washing tub 2 and the washing blade 3 are rotated, When the total laundry load amount is detected, only the laundry wing 3 is rotated to detect the bottom end amount of the separated laundry net 1 by the separated laundry net bottom end amount detection unit 6 , The separate laundry environment judging unit 7 judges whether or not the separated laundry environment is authorized based on the values calculated based on the total amount detected from the total laundry load detecting unit 5 and the separated laundry net lower end quantity detecting unit 6 In the case of a separate laundry environment, a normal separation washing cycle is executed. If it is determined that the washing environment is not the separate laundry environment, the abnormality notification unit 8 informs an abnormal alarm.

As described above, according to the present invention, in a fully automatic washing machine, relatively coarse laundry and soft laundry are put together into the washing tub 2, and when the separated laundry is not washed, It is possible to prevent the loss and the execution of the mis-operation in advance and to detect whether or not the laundry is put into the upper part of the separate washing net 1 and the separated laundry net 1, And the reliability is remarkably improved.
