The invention relates to a washing machine with an identification function and a washing method. The washing machine comprises a washing machine body and a clothes identification module, an RFID reader, and an RFID antenna. The clothes identification module comprises a plurality of RFID tags representing clothes classifications and/or materials. The RFID tags are placed on the washing machine body and can be separated from the washing machine body. In washing, the RFID tags are connected with to-be-washed clothes. After washing is finished, a user separates the RFID tags from the clothes and collects the RFID tags to the washing machine body. The RFID reader is used to read information of the RFID tags and transmit the information to a washing machine processor. The RFID antenna transmits radio-frequency signals among the tags and the reader. The washing machine solves problems that the RFID tags are not popularized on clothes and clothes intelligent identification cannot be realized. The method pushes intelligent identification of clothes which just remains in a theoretical research stage to a specific washing machine structure, so that intelligent identification of clothes without the RFID tags is realized. The washing machine realizes optimal washing ratio by minimum water consumption, minimum power consumption, and minimum detergent.
