Abstract

The utility model discloses a lower jet nozzle for a dish washer, which is arranged in the dish washer and used for spraying water to dishes which need to wash. The utility model comprises a spray arm which is jointed by an upper half arm and a lower half arm, wherein, the upper half arm and the lower half arm are respectively provided with an arc-bottom groove and a flat-bottom groove; the center of the upper half arm is provided with upward convexities by which pits are formed on the surface of the upper half arm; the center of the lower half arm is provided with a through hole in which a shaft is arranged; the upper and lower half arms are respectively provided with hemispheric dummy clubs which are provided with water jets. With the adoption of the structure, the utility model has the advantages that the water which flows through each of the water jets of the lower jet nozzle for the dish washer has even water pressure; the aggregation force is strong when the water reaches the water jets; the washing effect and the washing efficiency can be enhanced.

Description

Nozzle under the dish-washing machine

The utility model relates to a kind of flusher, is a kind of Nozzle of bowl washer that is used in the dish-washing machine to being sprayed water by wash up that is installed in specifically.

At present, nozzle under the dish-washing machine on the market, the surfaces externally and internally of its upper and lower half arm is the plane, and water jet is directly opened on this plane, when the water in the spray arm arrived the water jet place, it was not strong to gather power, and pressure is not high, be difficult to form water column, effect is relatively poor during wash dining set, and efficient is not high.Because the inside and outside face of upper and lower half arm of this nozzle is the plane, when entering the interior water of its central through hole in first arm bottom of arrival and to the shunting of the inner chamber both sides of spray arm, very inhomogeneous, make and not wait from the pressure of the water of each water jet ejection is high and low, also influenced clean result and efficient.

The purpose of this utility model is to provide nozzle under the dish-washing machine that a kind of clean result is good, efficient is high.

Nozzle under the dish-washing machine of the present utility model, comprise spray arm, this spray arm is formed by first arm (1) and second arm (2) butt joint, upper and lower half arm is respectively arc kerve and flat-bottom slot, first arm (1) center raises up, so that its inner surface forms pit, this pit is corresponding with the through hole at second arm (2) center; Axle (3) is arranged in the through hole at second arm (2) center, last water jet (6,5,4,7,8) and following water jet (10,11) are arranged respectively on upper and lower half arm (1 and 2), be characterized in that all there is hemispherical boss at upper and lower water jet place, water jet is opened on this hemispherical boss.

Because the hemispherical boss of oriented outer lug on upper and lower half arm of nozzle under the dish-washing machine of the present utility model, water jet is opened on this hemispherical boss.When the water in the spray arm chamber arrived water jet, it was strong to gather power, the pressure height, and the water of ejection can form water column, during wash dining set, can improve clean result and efficient greatly.In addition, because there is pit first arm inner surface center, and this pit is corresponding with the through hole at second arm center, when water when second arm central through hole enters and arrives the pit at first arm center, have an instantaneous delay, produce buffering, make that the current that flow to spray arm inner chamber both sides are more even.Like this, from the pressure of the water of each water jet ejection also relatively evenly, also can improve clean result and efficient greatly.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a nozzle partial schematic sectional view under the dish-washing machine of the present utility model;

Fig. 2 is the schematic top plan view of Fig. 1;

Fig. 3 is the elevational schematic view of Fig. 1;

Fig. 4 is the A-A cross-sectional schematic of the Fig. 2 through having amplified.

See Fig. 1, Fig. 2 and Fig. 4, nozzle comprises spray arm under the dish-washing machine of the present utility model, and this spray arm is made up of first arm 1 and second arm 2, and upper and lower half arm forms with corrosion resistant plate is cold rolling.Wherein, first arm 1 is processed into the arc kerve, and second arm 2 is processed into flat-bottom slot.The shape that raises up is processed at first arm 1 center, makes its inner surface form pit, and this pit is corresponding with the through hole at second arm 2 centers.See Fig. 4, fold occlusal technology is taked in upper and lower half arm 1 and the butt joint of 2 periphery, their periphery is interlocked, thereby constitutes a spray arm that narrows down gradually from the middle to both ends.See Fig. 1 and Fig. 3, the center of second arm 2 has through hole, leaving certain gaps uncovered by the economic plan on the through hole, and the hole of breach both sides is staggered along going to upper and lower, and makes circular hole become " screw ".Axle 3 be a plastic product, is processed with external screw thread on cylindrical on it, and this 3 is screwed in " screw " at second arm 2 centers.See Fig. 2, process three hemispherical boss on the both sides center line of first arm 1 respectively.Wherein all have

water jet

6,5,4 on three of a side hemispherical boss.In these three water jets, a water jet 4 at contiguous spray arm center is opened in the center of its hemispherical boss in place, and all the other two water jets are opened same one side of the hemispherical boss center line at its place.In three hemispherical boss of first arm 1 center opposite side, except that of centre, all have

water jet

7 and 8 on all the other two, these two water jets are opened same one side of the hemispherical boss center line at its place, and the direction of these two

water jets

7 and 8 disalignments just in time the direction with two water jets 6 of opposite side and 5 disalignments is opposite.In addition, first arm 1 one ends promptly also have an oblate water jet 9 in an end end of contiguous water jet 8.

See Fig. 3, second both sides, arm 2 center respectively process a hemispherical boss, and this two boss does not wait to the distance at center.Have water jet 10 and 11 on the boss, water jet 10 and 11 center line all tilt to the central point of second arm 2.

The utility model when work, with high-temperature wash liquid with certain pressure up and down with different directions, even continuous injection thick and fast.Simultaneously, spray arm at the uniform velocity rotates along the opposite direction of driving shaft by means of the spray power (reaction force) of liquid, makes the liquid with certain kinetic energy form three-dimensional stream and is ejected on the tableware that varies in size.
