The anti-crease rinsing step is performed before the final spin drying step. The anti-crease rinsing operation step is performed after the normal rinsing operation performed at least once is completed. The anti-crease rinsing operation step is performed to achieve a longer anti-crease rinsing time than the normal rinsing time in the normal rinsing process.

Description

Control method of washing machine rinsing process

technical field

The present invention relates to washing machines, and more particularly, to a method of controlling the rinsing process of a washing machine.

Background technique

Generally speaking, a washing machine is a device that completes the laundry washing operation by driving the agitator to rotate forward and reverse and using water flow to impact the laundry.

Traditional washing machines perform operations such as washing, rinsing and spinning. Various parameters, such as washing time, rinsing time, spin-drying time, washing water level, and the number of times of repeated rinsing operations, etc. are determined according to the amount and type of laundry to be washed. The rinsing operation sequentially includes: discharging washing water, spinning and rinsing, and the above-mentioned process will be repeated two to five times at a predetermined water level.

In the rinsing operation, the used washing water is first discharged from the water tub, and then the water tub is rotated at a high speed for a predetermined spin-drying time to remove moisture absorbed in the laundry. Next, water is input into the water cylinder to reach a reference water level determined according to the quantity and type of laundry, and then the agitator is rotated forward and reverse to perform rinsing. The purpose of the rinsing operation is to remove suds and detergent residue from the laundry.

In the rinsing process of the conventional rinsing operation, the water flow is directly delivered to the water tub, and then the laundry is rinsed. During this process, the clothes clinging to the wall of the washing tub are collected in the center of the inside of the washing tub during the spin-drying process of the rinsing operation. Accordingly, since the rinsing process of the rinsing operation is performed while the laundry is entangled, this cannot effectively eliminate the entangled state of the laundry, thereby making the laundry tangled.

In addition, when the spin-drying operation is performed in this case, the clothes in the spin-drying process will be wrinkled when the washing tub rotates at a high speed.

Contents of the invention

The object of the present invention is to provide a method for controlling the rinsing process of a washing machine, which can effectively prevent the clothes from being entangled, so that the clothes will not be wrinkled during the high-speed spin-drying operation.

Other objects and advantages of the present invention will be partly described in the following description, and partly embodied in the scope that is obvious from the description or can be learned from the practice of the present invention.

In order to achieve the above and other objects, the present invention provides a method of controlling a rinsing operation of a washing machine using an agitator to wash laundry, the method including the steps of performing a crease-proof rinsing operation, the step comprising: operating the agitator for an agitator operating time; and the agitator is off for an agitator off time, wherein: the agitator off time is longer than the agitator on time and the agitator on and off produces an anti-wrinkle wash flow that minimizes wrinkles in the laundry.

The anti-crease rinse step is performed before the final spin of the washing machine.

The anti-crease rinsing step is performed after the rinsing operation has completed at least one normal rinsing course.

The anti-crease rinse step is performed to achieve an anti-crease rinse time longer than the normal rinse time in the normal rinse process.

The agitator run time is shorter than the agitator run time during a normal rinse, and the agitator stop time is longer than the agitator stop time during a normal rinse.

Next, a method for controlling the rinsing process of the washing machine shown in FIG. 1 will be described with reference to FIGS. 3A and 3B .

FIG. 3A is a flowchart showing a method for controlling a rinsing process of the washing machine shown in FIG. 1 .

Referring to Fig. 1 and Fig. 2, the control unit 30 sends water into the water tank 2 to reach the water level predetermined by the user, and then drives the washing motor 5 through the washing motor drive unit 43 according to the weight of the clothes and the predetermined water level to make the agitator 4 rotate forward and reverse. change. In this way, in the washing step 100, the clothes are washed under the action of the water flow formed by the forward rotation and reverse rotation of the agitator 4 .

After the washing step 100 is completed, the control unit 30 completes draining, spin-drying and rinsing according to a predetermined rinsing time (eg, 13 minutes).

Specifically, the control unit 30 controls the drain driving unit 41 to open the drain valve 11 to discharge the used water from the water tank 2 . In addition, the control unit 30 rotates the washing tub 3 at a high speed to separate the washing water absorbed in the clothes, and controls the water inlet valve driving unit 40 to open the water inlet valve 10 to deliver clean water into the water tub 2 . Next, the control unit 30 controls the washing motor driving unit 43 to make the washing motor 5 rotate forward and reverse to make the agitator 4 rotate forward and reverse, thus completing the rinsing process 101 of the rinsing operation.

Next, the control unit 30 repeats the rinsing operation in steps 102, 103, and 104 for a predetermined number of times, for example, four times.

After the last rinsing process is completed, for example, after the rinsing step 104 is completed, the control unit 30 performs an anti-wrinkle rinsing step 105 to detangle the laundry, so that the fibers in the laundry absorb moisture and prevent wrinkles from forming in the laundry.

After performing the anti-wrinkle step 105, the control unit 30 completely discharges the washing water from the water tub 2 and rotates the water tub 3 at a high speed in step 106 to remove the washing moisture absorbed in the clothes to spin dry the clothes.

After the spin-drying operation 106 is completed, the control unit 30 controls the washing motor drive unit 43 to stop the washing motor 5 to end the entire washing process.

Fig. 3B is a flowchart showing the anti-crease rinsing step in Fig. 3A.

Referring to FIGS. 1 and 2 , when the anti-wrinkle rinsing step starts, the control unit 30 performs the sub-steps of draining wash water, spin-drying, and rinsing for a predetermined rinsing time.

Specifically, the control unit 30 controls the drain valve driving unit 41 to open the drain valve 11 to discharge the used wash water from the water tub 2 in the step 200 of draining the washing water.

After the washing water is discharged to the outside, the control unit 30 rotates the water tub 3 at a high speed to remove the washing water absorbed in the clothes in the spin-drying sub-step 201 to spin the clothes.

After the clothes are spin-dried, the control unit 30 controls the water-inlet drive unit 40 to open the water-inlet valve 10 in the water-intake step 202 so that washing water is input into the water tub 2 to reach a predetermined water level.

After the water intake is completed, the control unit 30 controls the washing motor drive unit 43 to drive the motor washing motor 5 in substep 203 to make the agitator 4 rotate forward and reverse for a first predetermined time (for example, one minute).

After the first predetermined time has elapsed, the control unit 30 stops the agitator 4 in sub-step 204 for a second predetermined time longer than the first predetermined time (for example four minutes). In this way, the anti-wrinkle water flow formed by the start and stop operation of the agitator 4 makes the clothes untangle. Accordingly, crease formation in the garment is largely eliminated.

After the second predetermined time has elapsed, the control unit 30 may repeat the above-mentioned sub-steps 203 and 204 again in sub-steps 205 and 206 . Accordingly, the tangle of the clothes can be further eliminated, thereby preventing creases from being formed in the clothes.

FIG. 4 is a timing chart of the operation of the agitator 4 in the normal rinsing process and the anti-crease rinsing process in the present invention.

As shown in FIG. 4, the time T for the anti-wrinkle rinsing course is set longer than the rinsing time T0 in normal rinsing courses (eg, rinsing course 1, rinsing course 2, rinsing course 3, and rinsing course 4 in FIG. 3A).

During the anti-wrinkle rinsing, the agitator 4 is operated for the agitator operation time T1, and then the agitator is stopped for the agitator stop time T2 which is longer than the agitator operation time T1, so that the clothes are detangled and the Fibers absorb wash water. In this way, the effect of preventing the clothes from wrinkling is achieved.

As described above, the present invention provides a method of controlling a rinsing operation of a washing machine that allows laundry to be spin-dried while eliminating entanglement, thereby minimizing creases in the laundry.

Although the present invention has been disclosed and described through several preferred embodiments, it should be considered that those skilled in the art may make various changes on this basis without departing from the invention protection scope and subject spirit defined by the claims. The protection scope of the present invention is defined by the claims and their equivalents.
