According to the installation structure of the spraying arm of the dish washing machine, the outer diameter of the spraying output pipe is a, the minimum diameter of the cross section of the clamping groove is b, the shortest distance between the corresponding V-shaped buckles on the two elastic clamping hooks is c, and the requirement that b is smaller than c is satisfied, so that the elastic clamping hooks and the clamping grooves are in clearance fit, the spraying arm and the spraying input pipe can smoothly rotate relative to the spraying input pipe, and meanwhile, the elastic clamping hooks and the clamping grooves are prevented from being accidentally disengaged in the rotating process.

According to the installation structure of the spraying arm of the dish washing machine, the outer side of the elastic clamping hook is provided with the convex rib so as to improve the elastic deformation capacity of the elastic clamping hook.

According to the installation structure of the spray arm of the dish washing machine, the boss which is used for being abutted to the end part of the spray input pipe is arranged in the spray output pipe, the spray input pipe can be limited by the boss, and the phenomenon of water leakage when a spraying device pours water into the spray arm and cleans foam can be prevented.

[ description of the drawings ]

The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the assembly of the present invention;

fig. 3 is a schematic structural view of the spray arm of the present invention;

fig. 4 is a schematic structural view of the spraying output tube of the present invention.

[ detailed description ] embodiments

The utility model provides a mounting structure of dish washer spray arm, is including locating spray output tube 1 on spray set 10 top output, locate spray arm 20 bottom input and be used for penetrating spray input tube 2 of output tube 1, locate the draw-in groove 3 that sprays the output tube 1 outside and at least two locate the bottom of spray arm 20 and be used for the elasticity pothook 4 of being connected with draw-in groove 3 buckle, elasticity pothook 4 and draw-in groove 3 clearance fit so that spray arm 20 can spray input tube 2 relatively together with spray input tube 2 and rotate.

In order to improve the stability of the buckling connection between the elastic hooks 4 and the clamping grooves 3, the number of the elastic hooks 4 is 2, and the two elastic hooks 4 are symmetrically arranged at two sides of the spraying input pipe 2.

In order to further improve the stability of the buckle connection and prevent the accidental tripping of the elastic clamping hook 4 and the clamping groove 3 in the working process, the section of the clamping groove 3 is V-shaped, and correspondingly, the V-shaped buckle 41 matched with the shape of the clamping groove 3 is arranged on the elastic clamping hook 4.

The outer diameter of the spraying output pipe 1 is a, the minimum diameter of the cross section of the clamping groove 3 is b, and the shortest distance between the corresponding V-shaped buckles 41 on the two elastic clamping hooks 4 is c, so that the condition that b is more than c and less than a is met.

In order to improve the elastic deformation capability of the elastic hook 4, a convex rib 42 is arranged on the outer side of the elastic hook 4.

A boss 11 used for abutting against the end part of the spray input pipe 2 is arranged in the spray output pipe 1. Preferably, the inner diameter of the input pipe 2 is smaller than the diameter of the boss 11, that is, when the input pipe 2 penetrates into the output pipe 1 and abuts against the boss 11, the end of the input pipe 2 covers the diameter of the boss 11, thereby preventing water leakage when the shower device 10 pours water into the shower arm 20 and cleans foam.

The utility model discloses during the installation, insert spray output tube 1 of spray set 10 with spray input tube 2 of spray arm 20 to make the V type on the elasticity pothook 4 of spray arm 20 bottom detain 41 elasticity cards and go into in the draw-in groove 3 that sprays output tube 1, can accomplish the installation of spray arm 20. During the use, spray set 10 pours water and clean foam to spray arm 20, thereby make spray arm 20 to the internal rotation of dishwasher spray clean foam and water (belong to prior art, because be provided with a plurality of injection mouths toward the equidirectional slope on spray arm 20, consequently spray arm 20 can spray output tube 1 relatively when spraying and rotate), spray arm 20 rotates the in-process that sprays, owing to detain 41 and V type draw-in groove 3 under stable buckle connected relation between the V type, guaranteed that spray arm 20 can not unexpected blowout and drop, and under boss 11 and the butt relation of spraying input tube 2, effectively prevented its phenomenon that appears leaking. When the shower arm 20 needs to be detached, the V-shaped buckle 41 on the elastic hook 4 is only required to be broken off so as to be disengaged from the clamping groove 3, and the shower arm 20 can be taken down conveniently.
