Abstract

The utility model relates to a water spray assembly of dish washer, including inlet tube, spray arm, nut, connecting piece and gasket, wherein the end of intaking of inlet tube is adorned admittedly in the inner bag of dish washer, the nut has been installed to its water outlet port, the connecting piece is arranged in the nut, the lower extreme of its outer lane corresponds to place on the inner ring up end of nut, add the spacer during it, the water inlet of spray arm stretches into the inner ring intracavity of nut, the outer hook card of interior couple and connecting piece inner circle lower part on its inner wall is in the same place, the inner ring inner wall clearance fit of its outer wall and nut, wherein the up end of the inner ring of nut is equipped with more than one overflow launder. The utility model discloses can reduce the friction between nut and connecting piece and the gasket, ensure that the spray arm is rotatory smooth and easy, reduce the wearing and tearing between nut, spray arm and the gasket simultaneously, correspondingly prolong the life of above each spare part to guarantee the normal work and the washing efficiency of spray arm.

Description

A kind of spray module of dish-washing machine

Technical field:

The utility model is a kind of spray module of dish-washing machine, belongs to the improvement technology of the spray module of dish-washing machine.

Background technology:

The spray module of prior art dish-washing machine comprises water inlet pipe 1, spray arm 2, nut 3, connector 4 and pad 5, wherein the water inlet end of water inlet pipe 1 is packed in the inner bag of dish-washing machine, its water outlet port is equiped with nut 3, connector 4 places in the nut 3, the lower surface correspondence of its outer ring is placed on the upper surface of interior ring 31 of nut, add dottle pin sheet 5 therebetween, the water inlet 21 of spray arm puts in the chamber of ring in the nut 3, inner hanging hook 211 on its inwall hangs over outer hanging hook 41 cards of connector 4 inner ring bottoms, the inwall matched in clearance of the interior ring of its outer wall and nut, during the dishwasher into operation of said structure, the water of water inlet pipe flows in the spray arm chamber by the water inlet of spray arm, penetrate outside the chamber by a plurality of delivery ports which is provided with are intensive again, polymodal current is used for cleaning tableware, also, spray arm provides power for moving into the rotation of water pipe delivery port, but according to active force and reaction force principle, when spray arm upwards penetrates current at a high speed, also can produce downward active force, active force increases the frictional force between nut and connector and the pad downwards, can cause the spray arm rotation to have some setbacks, and then influence the detersive efficiency of complete machine, and increased wearing and tearing between nut and the spray arm, reduced the service life of above each parts.

The utility model content:

The purpose of this utility model is to consider the problems referred to above and a kind of friction that can reduce between nut and connector and the pad is provided, guarantee the spray arm smooth rotation, reduce the wearing and tearing between nut and the spray arm simultaneously, the service life of corresponding prolongation nut and spray arm, the spray module of the operate as normal of assurance spray arm and the dish-washing machine of detersive efficiency.

The technical solution of the utility model is: a kind of spray module of dish-washing machine, comprise water inlet pipe, spray arm, nut, connector and pad, wherein the water inlet end of water inlet pipe is packed in the inner bag of dish-washing machine, its water outlet port is equiped with nut, connector places in the nut, the lower surface correspondence of its outer ring is placed on the upper surface of interior ring of nut, add the dottle pin sheet therebetween, the water inlet of spray arm puts in the chamber of ring in the nut, inner hanging hook on its inwall hangs over the plug-in dogging of connector inner ring bottom, the inwall matched in clearance of the interior ring of its outer wall and nut, the upper surface of the interior ring of wherein said nut are provided with an above overflow launder.

The utility model is owing to adopt the upper surface of encircling in nut to be provided with the structure of an above overflow launder, water in the water inlet pipe can flow in the overflow launder, these water make between nut and connector and the plane that pad contacts and form water membrane, moisture film can reduce the friction between nut and connector and the pad, guarantee the spray arm smooth rotation, reduce the wearing and tearing between nut, spray arm and the pad simultaneously, the corresponding service life that prolongs above each parts, thereby the operate as normal and the detersive efficiency of assurance spray arm.
