Title: SELF-ROTATING SPRAY DEVICE AND WASHING MACHINE
Abstract:
Disclosed are a self-rotating spray device (1) and a washing machine. The self-rotating spray device (1) comprises: a spray head (11), wherein a through hole through which a water flow passes is provided in the spray head (11), one end of the through hole is a water inlet (111) and the other end thereof is a water outlet (112), and the water inlet (111) is connected to a water inlet pipe; and a self-rotating nozzle (12), wherein the self-rotating nozzle (12) is arranged in the through hole, at the water outlet (112), of the spray head (11), and the self-rotating nozzle (12) comprises a hollow body (123), an impeller (121) arranged in the body (123), and a rotating shaft (122). A terminal end of the body (123) is a main spray orifice (1231); the body (123) is arranged to at least partially protrude from the water outlet (112); and circumferential spray orifices (1232) are provided in the part of the body (123). The impeller (121) is made to rotate by means of the impact from sprayed water flows, thus changing the direction of sprayed water of some of the water flow. The self-rotating spray device (1) substantially increases the spray range, improves spray efficiency and effects, and has a simple structure, fewer components and low costs, and is highly reliable.
