A kind of spray thrower of dish-washing machine, including rotating arm and stream commutator, rotating arm lower half portion in the middle part of have with
The mounting hole of stream commutator cooperation, the stream commutator include the main part in rotating arm and are located at outside rotating arm
Interconnecting piece, the main part be ring structure, centre bore be the intake tunnel coaxial with rotating arm, the side of main part is equipped with
Multiple circular centre bore settings, and it is intersected in the exhalant canal of its side wall, the inner cavity of described intake tunnel one end and interconnecting piece connects
It is logical, other end closing, and the end face indent of closed end, the pyramidal structure with diversion function is formed, the position of indent is fixed
Bearing is installed, the central axis of bearing and the top half of rotating arm connect.
The position of indent is equipped with the inserts of fixing bearing.
The part that the central axis passes through rotating arm is coated with fixture nut, and the surface of the rotating arm, which has to hide, to be fixed
The counterbore of nut.
The interconnecting piece is equipped with internal screw thread.
The exhalant canal is arc, and the arranged direction of all exhalant canals is identical, is equipped with and goes out inside the rotating arm
The tangent flow apron of aquaporin outboard end.
The inner end of the exhalant canal and the pyramidal structure are tangent.
The position of the indent of intake tunnel closed end, and axis is arranged in bearing by the spray thrower of the utility model dish-washing machine
The top half of the central axis and rotating arm that hold connects, so that being connected between one side rotating arm and stream commutator by bearing
Reduce pivoting friction between the two, reduces energy loss, the position of another aspect bearing is in the inside of rotating arm, and structure is more
It is compact.
Detailed description of the invention
Fig. 1 is the configuration schematic diagram of the utility model spray thrower.
Fig. 2 is the structural schematic diagram of the utility model spray thrower.
Fig. 3 is the sectional view of the utility model spray thrower.
Specific embodiment
As shown in Figures 1 to 3, a kind of spray thrower of dish-washing machine, including rotating arm 1 and stream commutator 2.Rotating arm 1 is by upper
Half part 11 and lower half portion 12 form, and the two mutually fastens sealing, is welded into one.The top surface of rotating arm 1, i.e. top half 11
Top surface be equipped with spray apertures 13.There is the mounting hole 14 cooperated with stream commutator 2 in the middle part of the lower half portion 12 of rotating arm 1.
The effect of stream commutator 4 is exactly that the water flow of vertical direction is converted into level under the premise of energy consumption is alap
The water flow in direction, the steady cavity inside for flowing into rotating arm 1.Stream commutator 2 include the main part 21 in the rotating arm 1 with
And the interconnecting piece 22 outside rotating arm 1, wherein main part 21 be ring structure, centre bore be with rotating arm 1 it is coaxial into
Aquaporin 23, the side of main part 21 is equipped with multiple circular centre bore settings, and is intersected in the exhalant canal 24 of its side wall.Water outlet
Channel 24 is arc, and direction is identical.
Interconnecting piece 22 is equipped with internal screw thread, for connecting water inlet pipe.23 one end of intake tunnel is connected to the inner cavity of interconnecting piece 22,
Other end closing, and the end face indent of closed end, form the pyramidal structure 25 with diversion function.The inside of exhalant canal 24
End is tangent with pyramidal structure 25, in addition, being equipped with the flow apron 15 tangent with 24 outboard end of exhalant canal inside rotating arm 1, makes
Water (flow) direction can smooth transition, reduce kinetic energy rejection.
The position of 21 indent of main part is equipped with the inserts 26 of fixing bearing 3, and the central axis 31 of bearing 3 is upper with rotating arm 1
Half part 11 connects.The part that central axis 31 passes through rotating arm 1 is coated with fixture nut 4, and the surface of rotating arm 1, which has, to hide admittedly
Determine the counterbore 16 of nut 4.
In one embodiment, 21 integrated injection molding of main part of inserts 26 and stream commutator 2, then with interconnecting piece
22 are welded into one, and guarantee each section bonding strength.
The working principle of the utility model is as follows:
Water flow enters back into intake tunnel 23 from the inner cavity that water inlet pipe enters interconnecting piece 22, then is entered by exhalant canal 24 and revolved
It is sprayed in the inner cavity of pivoted arm 1 by spray apertures 13.Stream commutator 2 is set at the mounting hole 14 of rotating arm 1, it can will be through connecting
The water flow in portion 22 is converted into horizontal flow direction, due to the guiding role of pyramidal structure 25, can reduce the kinetic energy damage of water flow as far as possible
Consumption.Bearing 3 is arranged in the position of the indent of 23 closed end of intake tunnel, and the central axis 31 of bearing 3 and rotating arm 1 is upper
Half part 11 connects, so that reducing turn between the two by the connection of bearing 3 between one side rotating arm 1 and stream commutator 2
Dynamic friction reduces energy loss, and in the inside of rotating arm 1, structure is more compact for the position of another aspect bearing 3.
