Example 1
As shown in fig. 1, 2 and 3, the invention provides a spray header of a washing machine, which comprises a spray header body 10, wherein a flow guide cavity 11 and a rotary driving assembly are arranged in the spray header body 10, one end of the spray header body 10 is provided with an opening end 12, and the other end is provided with a plurality of spray ports 13; the two ends of the diversion cavity 11 are respectively communicated with the opening end 12 and the spraying port 13; the rotary driving assembly is fixed with the inner wall of the diversion cavity 11, the open end 12 is coaxially and rotatably arranged in the water outlet 23 of the water inlet part 20, and the cross section of the outer wall of the spray header body 10 at the side of the open end 12 is circular; wherein,
rivers are from intaking in the piece 20 gets into shower head body 10, and rivers impact rotation driving assembly, and the impact force of rivers applys the effort along rivers flow direction to rotation driving assembly, and rotation driving assembly orders about shower head body 10 under the effect of rivers impact force and rotates, and when shower head body 10 rotated, change rivers flow direction to make rivers spray from many azimuth eruptions in a plurality of spray outlets 13, so that spray outlet 13 is rotatory to spray. Wherein, a plurality of spray opening 13 supplies a plurality of little rivers posts after being cut apart to spout, and under the condition that shower head body 10 constantly rotated, spray opening 13 applys the effort of spray opening 13 radial direction to corresponding little rivers post, realizes 360 all-round showers of shower head body 10 week side. In addition, the small water flow column sprayed falls under the self gravity, and the spraying to the space below the water flow is realized.
In one embodiment, one end of the showerhead body 10 having the shower openings 13 is a hemispherical structure, and the shower openings 13 are uniformly distributed on the hemispherical structure.
In one embodiment, as shown in fig. 1, one end of the showerhead body 10 having the shower openings 13 is a hemispherical structure, and the shower openings 13 are divided into two groups symmetrically disposed on two sides of the hemispherical structure. It should be understood that the bottom of the hemispherical structure of the showerhead body 10 may also be provided with a plurality of spray ports 13, not shown in fig. 1. Rivers impact rotation driving assembly, drive shower head body 10 and rotate, and rivers are cut into a plurality of little rivers posts blowout by a plurality of mouths 13 that spray, set up in hemispherical structure's both sides because of a plurality of mouths 13 that spray divide into two sets of symmetries, and rivers concentrate from hemispherical structure's both sides blowout, and rivers jet out dynamics is big, under shower head body 10 pivoted prerequisite, realizes 360 all-round sprays of high dynamics.
In an embodiment, one end of the shower head body 10 close to the plurality of shower openings 13 is opened, and water flow is sprayed out from the plurality of shower openings 13 and also can be sprayed out from the opening at the side of the shower openings 13, so that concentrated water flow spraying cleaning is performed in the direction pointed by the shower head body 10.
The rotary driving assembly comprises fan blades 14 fixedly connected to the inner wall of the diversion cavity 11. In one embodiment, the fan blades 14 are fixedly connected to the inner wall of the flow guiding cavity 11 through a rotating shaft. The water flow impacts the fan blades 14 to rotate the rotating shaft, so as to drive the fan blades 14 to rotate, the fan blades 14 cut the water flow, and the flow direction of the water flow is changed, so that the water flow is sprayed out from the plurality of spraying ports 13.
A surface of the fan blade 14 adjacent to the water inlet member 20 is inclined in the direction of water flow to guide the water flow impinging on the surface of the fan blade 14 toward the direction of the shower opening 13.
In an embodiment, as shown in fig. 1 and 2, the cross section of the diversion cavity 11 is circular, so that when the shower head body 10 rotates, the water flow in the diversion cavity 11 applies a uniform force to all positions of the inner wall of the diversion cavity 11. The fan 14 is spirally attached to the inner wall of the flow guiding cavity 11. Because the fan blades 14 are spirally arranged on the inner wall of the diversion cavity 11, water flow impacts the fan blades 14 after rushing into the diversion cavity 11, the fan blades 14 are subjected to different water flow impact forces along each point of the diversion cavity 11 in the axial direction, so that the axial stress on the inner wall of one section of the diversion cavity 11 is different, and the shower head body 10 rotates.
The number of turns of the spiral of the fan blade 14 is equal to or greater than one-half turn. That is, the number of turns of the fan blade 14 includes one half of a turn, three quarters of a turn, one turn, two turns, three turns, or even more turns, and is adjusted according to the space size of the diversion cavity 11, the width of the fan blade 14, and other factors that influence the magnitude of the impact force exerted on the fan blade 14 by the water flow, and thus details are not repeated here.
The longitudinal section of the fan blade 14 is triangular, and the fan blade 14 is in a gradually narrowing structure along the direction far away from the inner wall of the flow guide cavity 11, so that the weight of the fan blade 14 is reduced and water flow impacting on the surface of the fan blade 14 is guided while the fan blade 14 keeps strong connection force with the inner wall of the flow guide cavity 11.
In one embodiment, as shown in fig. 2, the width of the fan blade 14 gradually narrows along the water flow direction, so that the force of the water flow acting on the fan blade 14 gradually decreases along the water flow direction, which is beneficial for the fan blade 14 to drive the showerhead body 10 to rotate.
Example 2
As shown in fig. 3 and 4, the present invention provides a spraying device of a washing machine, which comprises a spraying device body 100, wherein the spraying device body 100 comprises a water inlet member 20 and the above-mentioned spray header body 10; wherein,
the water inlet piece 20 is provided with a water inlet channel 21, and both ends of the water inlet piece 20 are provided with a water inlet 22 and a water outlet 23 which are respectively communicated with the water inlet channel 21; the cross section of the water outlet 23 is circular, and further, the water inlet piece 20 and the water inlet channel 21 are both cylindrical, so that the structure is regular, the forming is convenient, and the cost is low;
the opening end 12 of the spray header body 10 is coaxially and rotatably arranged in the water outlet 23, and the water inlet 22 is connected with a water inlet pipeline of the washing machine; water flow rushes into the water inlet channel 21 from the water pipeline of the washing machine and then enters the flow guide cavity 11 to impact the rotary driving assembly to drive the spray head body 10 to rotate, and the water flow is sprayed out from the plurality of spray openings 13 in a multi-azimuth mode.
The shower head further comprises a sealing structure 30, wherein the sealing structure 30 is sleeved on the outer wall of the water inlet part 20 to seal the joint of the water inlet part 20 and the shower head body 10. It should be understood that fig. 3 and 4 do not show how the sealing structure 30 sealingly covers the connection of the inlet 20 and the showerhead body 10. The sealing structure 30 may include a combination of plastic and sealing rings to seal the rotational connection of the water inlet member 20 to the showerhead body 10 without interfering with the rotation of the showerhead body 10 relative to the water inlet member 20. In addition, any existing sealing structure capable of achieving the same function can be applied to the embodiment, and details are not repeated here.
Example 3
The invention provides a washing machine, which comprises the spraying device body 100, wherein the water inlet 22 of the water inlet part 20 of the spraying device body 100 is connected with a water inlet pipeline of the washing machine.
