The dissolution time of the agent improves the heating efficiency of the washing water of the washing machine, and further improves the washing rate of the washing machine.

The water inlet system further includes a second water inlet branch, the second water inlet branch being disposed in parallel with the first water inlet branch, and for communicating the water supply end of the washing machine and the water inlet end of the detergent box 1. Through the setting of the second water inlet branch, it is possible to selectively heat the washing water entering the washing box 1. If the water entering the detergent box 1 is not heated, the quick water inlet module 2 is closed and passed. The first water inlet branch and/or the second water inlet branch supply water into the detergent box 1. In one embodiment, the water supply to the detergent box 1 is simultaneously supplied through the first water inlet branch and the second water inlet branch when it is not necessary to heat the wash water entering the detergent box 1. Thereby, the efficiency of the water supply of the washing machine can be improved.

Specifically, the first water inlet branch further includes a first inlet pipe 3, and the water inlet end of the rapid heat inlet module 2 communicates with the drainage end of the first inlet pipe 3, and communicates with the water supply end of the washing machine through the first inlet pipe 3 . The second water inlet branch includes a second inlet pipe 4, one end of which is in communication with the water supply end of the washing machine, and the other end of which is in communication with the water inlet end of the detergent box 1.
