How to prevent the overflow of the washing machine

The present invention relates to a method for preventing a water overflow of a washing machine, and more particularly, in a washing machine installed in a kitchen to forcibly draining contaminated washing water by a pump, after the series of washing strokes are completed, water is continuously supplied to the reservoir to complete the washing valve. The present invention relates to a method for preventing a water overflow of a washing machine to prevent water overflow from occurring in advance.

In general, a washing machine used in our homes opens a water valve to wash water to be washed with a washing tank, and the washing water is detected by a water level sensor mounted on the outer wall of the water tank. When the water supplied by the washing water is completed at the proper level, the water supply valve is closed so that the water is not supplied any more, and a series of washing administrations, rinsing, and dehydration are performed.

As described above, when a series of washing strokes are performed while the water supply valve is opened and closed, and when the series of washing strokes are not washed, water is not supplied to the water supply valve. In the case where the general washing machine is made, even if the water is overflowed into the water tank by the washing water being supplied, the natural drainage is made, and only the waste of water is generated, so as not to wet the surrounding environment, thereby eliminating the need to clean the surrounding environment. But. In the case of a washing machine forcibly draining contaminated washing water generated during a series of washing strokes by a pump, when the water is continuously supplied to the water supply valve after completion of the series of washing strokes, the washing water being supplied is a natural drainage. As the water overflow of the reservoir is not made, soaking all of the surrounding environment, as well as the hassle of cleaning all the surrounding environment, still has the problem of causing waste of water.

An object of the present invention is a washing machine forcibly draining contaminated wash water to a pump during washing, if the water is continuously supplied to the abnormality of the water supply valve after a series of washing strokes, the pump is forced to detect the washing water stored in the water supply. By draining, the washing water to be supplied is prevented from overflowing the reservoir, thereby preventing the wetness of the surrounding environment caused by the overflow of the reservoir and preventing the hassle of cleaning the surrounding environment in advance. I want to be able to.

In order to realize the above object, the present invention detects whether a water supply is made in a reservoir after completion of a series of washing administrations, and when the water is being stored, the water level is detected and the water level is set to be detected. If it is determined that the above water level is reached, if the water level reaches a randomly set low water level, the step of driving the pump for forced drainage, and if the forced water drainage is completed in this step, if the forced drainage is not completed, continue Forced drainage, if the forced drainage is completed, characterized in that the step of stopping the drive of the pump and issuing an alarm.
