A kind of spray arm structure of dish-washing machine
Technical field
The utility model relates to dish-washing machine, and particularly a kind of spray arm structure of dish-washing machine belongs to the improvement technology that has the dish-washing machine spray arm now.
Background technology
Spray arm is the parts of wash dining set in the dish-washing machine; Liquid in the dish-washing machine flow to spray arm along pipeline after the washing pump pressurization; By the ejection of the hole on the spray arm, the reaction force that the liquid ejection produces makes the spray arm rotation, and the liquid of the spray arm that rotates in washing process ejection washes tableware from different perspectives.
General every layer of bowl basket of dish-washing machine is provided with a spray arm.Dish-washing machine bowl basket is rectangle mostly, and the spray arm rotational trajectory is circular, so exist fluid to spray the dead angle, the tableware pollutant that especially is placed on four angles of bowl basket is residual more.
Summary of the invention
The utility model purpose is to overcome the problems referred to above, and designs a kind of fluid projected area that can increase, and reduces and sprays the dead angle, the spray arm structure of the dish-washing machine of the clean rate of raising dish-washing machine.
The technical scheme that realizes the utility model purpose is: a kind of spray arm structure of dish-washing machine, and comprise conduit assembly and be connected the main jet arm on the conduit assembly, it is characterized in that, on conduit assembly, also be provided with the water pipe branch road, be connected with secondary spray arm on the water pipe branch road.
Have axisymmetric two water pipe branch roads on the above-mentioned conduit assembly at least.
Above-mentioned main jet arm passes through attaching nut's spinning on conduit assembly.
Above-mentioned secondary spray arm is installed on the water pipe branch road of conduit assembly through connector.
When the utility model uses, conduit assembly is installed on the bowl basket of dish-washing machine and gets final product.
The beneficial effect of the utility model is owing on conduit assembly, also be provided with the water pipe branch road, to be connected with secondary spray arm on the water pipe branch road; Therefore, during work, main jet arm and secondary spray arm spray the tableware in the bowl basket simultaneously; Increase the fluid projected area, reduced the injection dead angle, improved the clean rate of dish-washing machine; Stable performance, simple and reliable for structure, can be adaptable across the fountain dish-washing machine.
Description of drawings
Fig. 1 is installed in the stereogram in the dish-washing machine bowl basket for the utility model;
Fig. 2 is installed in the vertical view in the dish-washing machine bowl basket for the utility model;
Fig. 3 is the explosive view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of spray arm structure of dish-washing machine comprises conduit assembly 2; Main jet arm 3, secondary spray arm 4, connector 5; The attaching nut 6, and during use, conduit assembly 2 is installed on the bowl basket 1 of dish-washing machine; On conduit assembly 2, secondary spray arm 4 is installed on the water pipe branch road 21 of conduit assembly 2 through connector 5 main jet arm 3 through attaching nut's 6 spinnings.
At least be provided with axisymmetric two water pipe branch roads 21 on the above-mentioned conduit assembly 2, every water pipe branch road 21 is provided with a secondary spray arm 4.
During the work of the utility model; After dish-washing machine started, fluid flow to main jet arm 3 and secondary spray arm 4 by the pressurization of the pump on the dish-washing machine through spray arm conduit assembly 2, through water flow pressure; Make 3 spray arms rotary work simultaneously; Increase the fluid projected area, reduced the injection dead angle, improved the clean rate of dish-washing machine.
