Recognition method for load size of roller washing machine

Abstract

The invention relates to the field of washing machines, in particular to a recognition method for the load size of a roller washing machine. The recognition method includes the following steps of parameter setting, water level setting, load size judging and washing mode selecting. According to the recognition method, neither a structural alteration of an original washing machine nor additional arrangement of peripheral electric devices is needed, and the method is suitable for washing machines with variable frequency motors or series motors, so that cost for load recognition is reduced, and the service life of the washing machine is prolonged.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a method for identifying the load size of a drum washing machine. Background technique [0002] At present, the common problem of drum washing machines is that the adjustment of washing water consumption and washing time is limited by the parameter settings of the washing machine when it leaves the factory. Generally, the water volume of washing machines is divided into three levels, namely high, medium and low; The time is generally set to 40min-2h. In view of this situation, the user usually only considers the amount of clothes when choosing the amount of water and setting time, but in the actual washing process, the setting of water amount and time is also related to the texture of the clothes and the dirtiness of the clothes. For example, some very absorbent cotton High-quality clothes will absorb a lot of water during the washing process, even if it is just one piece, it nee...

Problems solved by technology

[0002] At present, the common problem of drum washing machines is that the adjustment of washing water consumption and washing time is limited by the parameter settings of the washing machine when it leaves the factory. Generally, the water volume of washing machines is divided into three levels, namely high, medium and low; The time is generally set to 40min-2h

In view of this situation, the user usually only considers the amount of clothes when choosing the amount of water and setting time, but in the actual washing process, the setting of water amount and time is also related to the texture of the clothes and the dirtiness of the clothes. For example, some very absorbent cotton High-quality clothes will absorb a lot of water during the washing process, even if only one piece needs a lot of water, many users may only choose the lowest amount of water when they use it again, resulting in insufficient load of the washing machine, which will reduce the service life of the washing machine

[0003] Secondly, the biggest dissatisfaction of current customers with drum washing machines is that the washing time is too long. Any washing program takes one to two hours. Long time, resulting in waste of electricity

[0004] Therefore, the difficulty that the existing washing machine urgently needs to overcome is: it is necessary to identify the size of the load in the bucket, and there are two identification methods currently used, but both have great defects. The recognition effect is not good; secondly, the industry needs to add peripheral electrical devices to identify the load size, which requires re-investment of funds, and the structure of the whole machine needs to be changed, resulting in high cost
