Abstract

The present invention, when the overflow water is carried out to remove the foreign matter floating on the surface after washing or rinsing, even if the water is not supplied to the overflow outlet position, the floating foreign matter quickly through the overflow outlet through the overflow water flow By discharging, it is possible to shorten the washing time and reduce the water supply.

To this end, in the present invention, after completion of the washing or rinsing mode, the water supply valve is turned on to supply water into the washing tank 1 and simultaneously rotate the washing blade 2 in one direction so that the central portion is concave by the centrifugal force. By forming a, it is a washing administration control method of the washing machine so that the floating foreign matter is quickly discharged through the overflow outlet even in the state of not supplying water to the overflow outlet (3) position.

Description

Washing stroke control method of washing machine

The present invention relates to a washing stroke control method of a washing machine, and more particularly, to enable an overflow water supply to be more effectively performed to effectively remove floating foreign matters after washing or rinsing.

In general, a washing machine is a device for removing various contaminants attached to clothes, bedding, etc. by using the emulsion action of the detergent and the friction action of the water flow due to the rotation of the pulsator and the impact action of the pulsator on the laundry. .

In the case of washing using such a conventional washing machine, as shown in FIGS. 1 and 2, after completion of washing or rinsing, water for overflow is performed immediately before draining the washing water or the rinsing water.

This is to prevent a phenomenon in which floating foreign matters such as seams floating on the water surface in the washing tank 1 stick to the cloth again and remain after washing or rinsing.

That is, after washing or rinsing, washing water or rinsing water overflowing the water by overflowing the washing water or rinsing water that overflows the overflow level and is discharged through the overflow outlet 3 by flooding the tap water. To be discharged with.

At this time, the washing water or rinsing water that flows out to the drain pipe 6 through the overflow outlet 3 is discharged out of the washing machine through the drain hose 7 through the drain pipe 6.

However, in this conventional art, when overflow water is supplied to discharge the floating foreign matter, the water supply must be continued until the water level in the washing tank 1 is more than the overflow outlet 3 position and naturally floods.

Therefore, since a large amount of tap water must be supplied into the washing tank, tap water was wasted.

In addition, since floating foreign matters floated on the water are discharged together when the washing water or the rinsing water is overflowed, the discharge is not made quickly but progresses gradually, and the overall washing time is increased.

The present invention is to solve the above problems, when the overflow water is carried out to remove the foreign matter floating on the water surface after completion of the washing or rinsing mode, formed by the centrifugal force in the state that is not supplied to the overflow outlet position It is an object of the present invention to provide a washing administration control method of a washing machine to reduce the washing time and reduce the water supply of tap water by allowing foreign matter to be quickly discharged through the overflow outlet by the overflow water flow.

In order to achieve the above object, the present invention, after the washing or rinsing mode is completed, the water supply valve is turned on to supply water, and at the same time, the washing blade is rotated in one direction to form a parabolic overflow water stream having a central concave by centrifugal force. For example, the washing administration control method of the washing machine is added to the step of allowing the floating foreign matter is discharged through the overflow outlet.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 4 as follows.

Figure 3 is a flow chart illustrating a washing mode control process of the present invention, Figure 4 is a longitudinal sectional view schematically showing an overflow water supply state according to the present invention, the present invention after washing or rinsing mode, water supply valve (not shown) ) By supplying water to the washing tank 1 and rotating the washing blade 2 in one direction to form a parabolic overflow water flow concave by the centrifugal force, thereby supplying water to the overflow outlet 3 position. It is configured to be quickly discharged through the overflow outlet (3) even when the state is not.

The operation of the present invention configured as described above is as follows.

Water supply proceeds as the water level is automatically or manually selected, and the process of washing or rinsing after the completion of the water supply is generally omitted, and thus, the description thereof will be omitted and description will be mainly given for the overflow water supply for discharging foreign substances.

First, after the washing or rinsing mode is completed, the washing blade 2 driving motor 4 is turned on in the state in which the washing water or the rinsing water is not discharged so that the washing blade 2 rotates at a high speed in one direction.

As a result, centrifugal force acts on the washing water or the rinsing water, so that the upper water flow surface 5 in the washing tank 1 draws a parabolic concave center.

On the other hand, at the same time as the high-speed rotation of the washing blade 2 in accordance with the drive of the drive motor 4, the water supply valve is turned on (on), the water supply for overflowing the wash water or rinsing water proceeds.

Therefore, the water flow at the upper edge of the water flow in the washing tank 1 rises to the position higher than the overflow outlet 3 by the action of the washing blade 2.

That is, even when water is supplied in a small amount compared to the prior art, the overflow of washing water flows out through the overflow drain pipe 6 to occur.

At this time, foreign matter suspended on the surface of the washing water or the rinsing water is also swept away by the overflowing water flow, exits the drain pipe 6 through the overflow outlet 3, and finally discharges to the outside through the drain hose 7. do.

That is, according to the present invention, after the washing or rinsing mode is completed, the water supply valve is turned on before the water is drained and the overflow water is supplied, and the washing blade 2 is rotated in one direction to generate the overflow water flow. (3) It is possible to discharge the floating foreign matter quickly without supplying water to the position.

On the other hand, Figure 5 is a flow chart illustrating a washing administration control process according to another embodiment of the present invention, after the washing or rinsing mode is completed, the water supply valve is turned on to perform water supply and at the same time determine the water level of the washing or rinsing water When is more than a predetermined water level immediately washing blade (2) is rotated in one direction at high speed to generate an overflow water flow.

In addition, when the water level does not reach the predetermined level by turning on the water supply valve and determining the level of the washing water or the rinsing water, the level of the washing water or the rinsing water reaches the predetermined level by water supply. The washing blade 2 is rotated at a high speed in one direction to generate an overflow water flow.

On the other hand, after the overflow action is completed by the water supply and overflow water flow for the discharge of floating foreign matter as described above, the drainage action is continued.

As described above, the present invention, when washing or rinsing, when the overflow water is carried out to remove the foreign matter floating on the water surface, the floating foreign matter with the overflow water flow even if the water is not supplied to the overflow outlet (3) position By discharging through the overflow outlet 3, unnecessary waste of tap water can be reduced.

In addition, the discharge of foreign matter by the forcibly generated water flow can be made in a short time, it is possible to provide the consumer with convenience for faster washing by reducing the overall time required for washing.
