Description

How to clean the washing machine

The present invention relates to a cleaning method of a washing machine, and in particular, the final administration of a series of washing administration water to wash the water during the main dehydration so that the dewatering while adsorbed or remaining foreign substances and contaminants on the outer wall of the washing tank with the water supplied wash water Thus, the present invention relates to a cleaning method of a washing machine in which an outer wall of a washing tank is always kept clean after dehydration is completed.

In general, when washing laundry in a washing machine, foreign matters or contaminants on the laundry are separated into the laundry by detergent and water friction, and then washing is performed. Then, when the washing is completed, the foreign matter and contaminants separated from the laundry are washed in the washing water. In this case, the foreign matter and contaminants are discharged in a floating state at a lighter weight than the wash water, so that the foreign matter and contaminants are not completely discharged and are adsorbed and remain on the outer wall of the washing tank for a long time. When used, the outer wall of the washing tank is more easily adsorbed by air adsorption and remaining foreign substances and contaminants to further soil the outer wall of the washing tank, and the foreign matter and contaminants adsorbed on the outer wall of the washing tank are washed on the outer wall of the washing tank. Separated from three In some cases, the case where the re-adsorption of water is occurred was to have the problem of not be able to wash out the laundry or clean laundry or hygienic yet.

Therefore, conventionally, after each stroke is completed during washing, water is supplied to the outer wall of the washing tank while washing the water between the washing tank and the water tank while washing the foreign substances and contaminants remaining in the washing tank. And it can wash the remaining foreign matter and contaminants, but if there is a problem that can not be washed for the adsorption and remaining foreign matter and contaminants after the series of washing administration is completed, the water supply between the washing tank and the reservoir separately after the series of washing administration is completed While there is a drainage to clean, but the overall washing completion time due to water supply and cleaning has had a problem.

An object of the present invention is to supply the wash water to the water storage tank during the final dehydration of the series of washing administrations, and to dehydrate the wash water by washing the foreign matter and contaminants adsorbed or remaining on the outer wall of the washing tank. It is intended to maintain cleanliness on the outer wall of the washing tank after the administrator's dehydration is completed.

In order to achieve the above object, the present invention is a step of performing a series of washing and rinsing stroke in a state in which a cleaning mode for cleaning a washing tank is set in a washing machine, and determining whether the cleaning mode is selected after completion, and in the step If the cleaning mode is not selected, the washing tank is rotated at a high speed and the last step of dehydration is completed and the step is completed. If the cleaning mode is selected at this stage, the washing tank is rotated at a high speed and the water supply is opened. Cleaning during water supply, determining whether the cleaning is completed for a predetermined time in the step, and if the cleaning is completed for an arbitrarily set time in the step, proceeding with the final dehydration of the final administration to stop the water supply; , The last administrator's pattern with the water supply stopped at the above step Be characterized by a phase made of an advancing the last administration of the dehydration and complete until the dehydration is complete, it is determined been completed.
