The baffle plate can also be provided with a water flow channel communicated with the water outlet end 62 of the first part 6, so that when the door body 4 is closed, water flow enters the washing drum 2 of the washing machine.
Further, as shown in fig. 5-10, the water outlet end 62 of the first member 6 is provided with at least one first spraying hole 621, and/or the baffle is provided with at least one second spraying hole 71 communicated with the first spraying hole 621, preferably, the water outlet end 62 comprises four first spraying holes 621, and the baffle is provided with four second spraying holes 71 communicated with the first spraying holes 621. When the water flows through the water outlet end 62 of the first member 6, the spraying water flow is formed through the first spraying holes 621 and/or the second spraying holes 71, so that the clothes can be wetted more effectively.
When the door 4 closes the laundry inlet 3 for putting laundry, the plugging unit 8 is in contact connection with the baffle, i.e. they are attracted and contacted with each other by magnetic attraction, the four first spraying holes 621 of the water outlet end 62 are communicated with the four second spraying holes 71 of the magnetic second component 7, and water flow can flow through the water inlet pipe 5 and the water inlet device and enter the washing drum 2 of the washing machine, so as to realize the washing function.
