It should be noted that, the two adjacent second fastening portions 22 are spaced apart in the circumferential direction to form a notch, and the first fastening portion 43 may extend into one side of the second fastening portion 22 away from the first spray arm 10 through the notch, so that the first fastening portion 43 and the second fastening portion 22 are conveniently fastened and matched, and the connection is convenient and reliable.
In some embodiments of the present invention, referring to fig. 5 and 7, the spacer 50 is an antifriction member, the spacer 50 is sleeved outside the mounting portion 21, and the spacer 50 is located between the abutting portion 42 and the snap ring 30 in the axial direction of the second spray arm 20. In other words, the abutment 42 and the snap ring 30 play a limiting role on the spacer 50 in the axial direction, and it is understood that the spacer 50 can play a role in reducing friction between the abutment 42 and the snap ring 30 when the first spray arm 10 rotates relative to the second spray arm 20, so as to reduce wear on the contact surface of the abutment 42 and the snap ring 30, and ensure the reliability of the operation of the spray arm assembly 100. For example, the gasket 50 may be made of a material having a low coefficient of friction, such as metal.
Alternatively, referring to fig. 6 and 7, the spacer 50 is rotatably connected to the mounting portion 21, and it is understood that the spacer 50 is sleeved on the mounting portion 21 and rotatable relative to the mounting portion 21, and friction between the snap ring 30, the abutment portion 42 and the spacer 50 can be reduced by rotatably connecting the spacer 50 to the mounting portion 21, which is advantageous in reducing energy loss and thus improving energy efficiency.
In some embodiments of the present invention, referring to fig. 1 and 2, a first driving hole 13 is provided on a first spray arm 10, the first spray arm 10 rotates in a first direction by a water spray reaction force at the first driving hole 13, a second driving hole 26 is provided on a second spray arm 20, and the second spray arm 20 rotates in a second direction by a water spray reaction force at the second driving hole 26, the first direction being the same as or opposite to the second direction.
For example, in some examples, the first direction of rotation of the first spray arm 10 is opposite to the second direction of rotation of the second spray arm 20, and when the water columns are sprayed from the first driving hole 13 of the first spray arm 10 and the second driving hole 26 of the second spray arm 20 at the same time, the first spray arm 10 and the second spray arm 20 are rotated at the same time, and the directions of rotation of the two are opposite, wherein, the first spray arm 10 rotates counterclockwise, the second spray arm 20 rotates clockwise, or the first spray arm 10 can also rotate clockwise, and the second spray arm 20 can rotate counterclockwise, at this time, the water columns sprayed from the first driving hole 13 of the first spray arm 10 and the second driving hole 26 of the second spray arm 20 are sprayed in opposite directions, and when the water columns sprayed from the first driving hole 13 and the second driving hole 26 are simultaneously dropped on the inner wall of the dish or dish washer, the direction of washing after the sprayed water columns are inconsistent due to the fact that the sprayed water columns are sprayed on the inner wall of the dish or dish washer is sprayed on the inner wall of the dish or dish washer, so that the water columns sprayed from the first driving hole 13 and the second driving hole 26 are rubbed on the inner wall of the dish or dish washer can generate a cleaning effect of the dish or dish washer, and the dish washer can be improved, and the washing effect of the dish or dish washer can be guaranteed. In addition, the second spray arm 20 and the first spray arm 10 are rotated in opposite directions, so that the water sprayed from the second spray hole 28 of the second spray arm 20 and the water sprayed from the first spray hole 14 of the first spray arm 10 can generate kneading force on the tableware, thereby further improving the cleaning effect of the spray arm assembly 100.
For another example, in other examples, when the first direction of rotation of the first spray arm 10 is the same as the second direction of rotation of the second spray arm 20, that is, the first spray arm 10 and the second spray arm 20 rotate in the same direction, the spray amount of the spray arm assembly 100 can be increased, which is also beneficial to improving the cleaning effect of the spray arm assembly 100. The aperture of the first driving hole 13 and the aperture of the second driving hole 26 are changed, so that the driving force of the first driving hole 13 to the first spray arm 10 and the driving force of the second driving hole 26 to the second spray arm 20 can be changed, and the rotation speeds of the first spray arm 10 and the second spray arm 20 are changed, so that the second spray arm 20 and the first spray arm 10 realize the same-speed same-direction rotation or different-speed same-direction rotation.
The washing appliance according to an embodiment of the present invention includes: the spray arm assembly 100 according to the above-described embodiment of the present invention. The washing electric appliance can be a dish washer, a fruit and vegetable washing machine, a medical washing machine and the like with a washing function.
According to the washing appliance provided by the embodiment of the invention, by arranging the spray arm assembly 100 according to the embodiment of the invention, on the basis of realizing the relative rotatability of the first spray arm 10 and the second spray arm 20, the spray arm assembly 100 can be simply assembled and disassembled, the subsequent cleaning and maintenance of the spray arm assembly 100 by a user are facilitated, the spray arm assembly 100 is facilitated to be clean, the tableware cleaning effect can be enhanced, and the use experience of the user is improved.
