Benefits of technology

The present invention is about a washing machine that can automatically determine the amount of detergent needed based on the type of detergent and the weight of the laundry. The machine has a detergent storing unit that contains a large amount of detergent and supplies the proper amount of detergent to the washing unit as needed. The machine also has a reading unit that receives a signal from a data tag, such as a detergent data tag or a barcode tag, and obtains data from the tag to control the amount of detergent supplied to the main body. Additionally, the machine may have a contamination degree sensor to sense the level of contamination in the laundry. The technical effects of this invention include automated detergent dosage, efficient detergent usage, and improved washing efficiency.

Problems solved by technology

However, since a user directly measures the amounts of the detergents and puts the detergents into the detergent box 20, the conventional washing machine causes a difficulty in putting the proper amounts of the detergents into the detergent box 20 according to the kinds of the detergents, the weight of the laundry, or the contamination degree of the laundry.
Further, since designated amounts of the detergents required to perform the washing of the laundry one time must be put into the detergent box 20, the conventional washing machine causes inconvenience of supplying the detergents to the inside of the detergent box 20 whenever a user wants to wash laundry.
