Example one

As shown in fig. 1 to 5, the present embodiment provides a spraying device 100 for a drum washing machine, wherein the spraying device 100 is communicated with a water inlet pipeline of the drum washing machine and can be used for feeding water into the drum washing machine.

Specifically, the spray device 100 includes a water inlet fitting 110 and a spray nozzle 120 that communicate with each other. The water inlet joint 110 has a water inlet end 111 and a water outlet end 112, and the inner diameter of the water inlet joint 110 gradually decreases from the water inlet end 111 to the water outlet end 112. The spray nozzle 120 is disposed on the water outlet end 112, and the water outlet of the spray nozzle 120 has a certain opening angle β. As shown in fig. 4, the opening angle β of the shower nozzle 120 in the present embodiment is 90.2 ° ± 1 °.

In the above solution, the inner diameter of the water inlet joint 110 gradually decreases from the water inlet end 111 to the water outlet end 112, and the flow rate and the water pressure of the shower water are gradually increased in the process of passing through the water inlet joint 110, so that the shower water at the water outlet end 112 enters the shower nozzle 120 at a higher water pressure and flow rate and is sprayed out, and the shower water can have a longer spraying distance and a higher spraying force. The farther spraying distance ensures that the spraying water can be directly sprayed to the clothes to be washed, the larger spraying force is beneficial to washing stains on the surfaces of the clothes, and the washing ratio of the clothes is improved.

The spray nozzle 120 with a certain opening angle beta can make the spray water spray out in a diffusion manner, so that the spray area is increased, more clothes can be under the coverage area of the spray water, the clothes can be quickly wetted when water enters through the spray device 100, and the wetting degree of the clothes is more uniform.

Further, the opening of the spray nozzle 120 is disposed toward one side of the water inlet joint 110, and an included angle α is formed between the central axis of the spray nozzle 120 and the central axis of the water inlet joint 110. Preferably, said angle α is greater than 90 °.

Further, the lower wall 122 is disposed to be inclined away from the water outlet end 112 of the water inlet joint 110, and the surface of the upper wall 121 facing the lower wall 122 is inclined in the same direction as the lower wall 122.

In the above scheme, the lower wall 122 is arranged to be inclined downward, and the shower water is sprayed obliquely downward along the upper surface of the lower wall 122. The lower surface of the upper wall 121 is also arranged to extend downward, so that the upper and lower widths of the water jet are narrower, and the spraying speed of the spray water is further increased.

In a further aspect of this embodiment, a positioning protrusion 113 is disposed on a sidewall of the water inlet joint 110, and a height of the positioning protrusion 113 protruding from the sidewall is gradually increased from the water inlet end 111 to the water outlet end 112 of the water inlet joint 110.
