The door seal 5 is located between the inlet of the outer drum and the glass bowl 21 of the door. The spray device includes a spray head 6, a water inlet pipe 7, and a water inlet valve 8. The spray head 6 is located at the upper end of the inlet of the inner drum 4, and is positioned between the door seal 5 and the glass bowl 21. Water from the water inlet pipe 7 is sprayed through the spray head 6 onto the bottom and lower-middle area of ​​the rear wall of the inner drum 4, evenly wetting the laundry 9.

[0044] Figure 3 This is a three-dimensional structural diagram of the spray head 6 provided in an embodiment of the present invention. Figure 4 for Figure 3 A cross-sectional view of the central spray head 6 along its long axis. (See diagram below.) Figures 3-4 As shown, the spray head 6 includes a spray head body 61, one end of which forms a water inlet port 62 and the other end forms a water outlet port 63; a flow channel 64 is formed inside the spray head body 61 to connect the water inlet port 62 and the water outlet port 63. Figure 3 and Figure 4 In this invention, a spray head inlet pipe 65, which communicates with the flow channel, can also be connected to the water inlet port 62 of the spray head. However, the invention can also be achieved by directly connecting the spray head 6 to the water inlet pipe 7. Those skilled in the art should understand that whether or not to design the spray head inlet pipe 65 can be determined according to the actual situation.

[0045] A baffle plate 66 is provided on the inner wall surface of the spray head body 61 located upstream of the flow channel 64. The baffle plate 66 allows water flowing into the flow channel 64 from the inlet port 62 to disperse to the surrounding area. One end of the baffle plate 66 is connected to the inner wall surface of the upstream side of the flow channel, and the other end extends to the inner wall surface of the other side of the flow channel 64, forming a first gap L1 with the inner wall surface of the other side.

The first end 661 is connected to the inner wall surface on the upstream side of the flow channel, and the width of the water guide channel gradually increases from the first end 661 to the second end 662, so that the water flowing into the flow channel from the water inlet port is dispersed to the surrounding area under the action of the water guide channel.

[0046] The spray head body 61 forms a baffle 67 on the inner wall of the other side of the flow channel 64. The baffle 67 has an flared structure, and the inner wall of the baffle forms the inner wall of the other side that is separated from the water baffle 66 by a first gap L1.

[0047] like Figures 6-8 As shown, the spray head body 61 has a cutout 68 formed on the flow channel wall connected to the baffle plate 66. A second gap L2 is left between the upper edge of the cutout and the baffle plate, allowing water flowing into the flow channel from the inlet port to flow in a direction different from the first gap L1 through the second gap L2. Figure 8As shown, there are two hollow holes or cuts 68 which are interconnected. The cuts 68 can also be designed as hollow holes, as long as the water flowing into the flow channel from the water inlet port can flow in a direction different from the first gap L1 through the second gap L2, and all fall within the scope of the claims of the present application. The hollow holes or cuts 68 are directed towards the door seal 5 and the glass bowl 21, and the water flowing out of the hollow holes or cuts 68 is sprayed on the door seal and the glass bowl 21, which can clean the foam remaining on the door seal and the glass bowl 21.
