Problems solved by technology

[0002] Existing tubular nozzles have the following characteristics: the side wall is provided with a water outlet hole that drives the nozzle to rotate around its axis, but the direction of water spraying is basically parallel to the cross section of the nozzle, and the direction of water spraying is single. In the plane where the cross-section is parallel, the sprayed water column is relatively single, and the ornamental value is not strong
[0003] Some of the same nozzles of the existing spray cleaning devices cannot directly wash the front and back of the object at the same time, and some nozzles rotate in a single direction or can only adjust the angle of the two-dimensional plane, and cannot adjust the angle in the three-dimensional space, so that it cannot be changed flexibly The spraying direction and spraying area, and its rotation or adjustment of the angle of the two-dimensional surface are realized by electrical equipment, and some are realized by many balls with spray holes, which increase the complexity of the spray cleaning device. Increased manufacturing difficulty and manufacturing cost
[0004] The existing dishwashers can only directly flush the front of the dishes with one nozzle. Although the front of the dishes is generally inclined towards the nozzle, the distance between the dishes is relatively close, and some parts of the front of the dishes are not easy to be washed directly. The part that is directly washed on the back of the dish is smaller, especially the farther away from the nozzle on the front and back, the less likely it is to be directly sprayed.
The parts on the front of the dishes that are not easy to be washed and the back of the dishes can only be washed by the splashing of the water flow or the natural downward flow of the water flow. In this way, the washing force is greatly reduced, and the washing is relatively slow, and it is not easy to clean the dishes in a short time

Embodiment 1

[0036] Refer to attached Figure 1-Figure 2 : A sprinkler head, comprising a tubular water spray pipe 1, one end of the water spray pipe 1 is open (water inlet), the other end is connected with a cover plate 13, the side wall of the water spray pipe 1 is provided with a number of water spray, and The water spray hole 11 that drives the water spray pipe 1 to rotate in one direction around the central axis, the water spray hole 11 includes a water spray hole 11a and a water spray hole 11b, and the water discharge direction of the water spray hole 11a is biased towards one end of the water spray pipe 1 , the water outlet direction of the water spray hole 11b is biased towards the other end of the water spray pipe 1; the water spray holes 11a are arranged in several columns at equal intervals along the circumference of the water spray pipe 1, and there are several water spray holes 11a in each column, and along the The water spray pipes 1 are arranged at equal intervals in the axi...

Embodiment 2

[0039] Refer to attached Figure 3-Figure 5 , a spray washing device, comprising the water spray pipe 1 in embodiment 1, the water spray holes 11a of the same row and the cross section angle of the water spray pipe 1 are the same, the water spray holes 11b of the same row and the water spray pipe 1 cross section The included angles are the same, so that the sprayed water columns of the same column can be prevented from intersecting each other, and the impact force can be prevented from canceling each other. The part of the water spray pipe 1 close to the opening is covered with a connecting pipe 2, and a connecting sleeve 3 connecting the outer walls of the two is provided between the water spray pipe 1 and the connecting pipe 2, and a friction mechanism for assisting the twisting of the water spray pipe 1 And a concentric mechanism that keeps the two in the direction of the concentric axis; the connecting sleeve 3 is rotatably connected with the water spray pipe 1, and the co...

Embodiment 3

[0047] A dishwasher, comprising the spray washing device described in Embodiment 2, the spray washing device is arranged on the inner cavity of the dishwasher, and the connecting pipe is connected to a water source for washing dishes. The arrangement direction of the dishes is parallel to the axial row of the water spray pipes, and the dishes are not easy to be placed obliquely. The second collision head can be provided with a plurality of, but must have a second collision head and the dish to be on the same side of the water spray pipe. The angle between the water spray direction of each water spray hole a and the cross section of the water spray pipe is 30 degrees, and the angle between the water spray direction of each water spray hole b and the cross section of the water spray pipe is 30 degrees. Since the front side of the dish (the side where the food is placed) is generally dirty, the back side is generally not dirtier than the front side, so the front side of the dish ...

Abstract

The present invention designs a spraying device, especially relates to a spray head. The spray head comprises a tubular water spray pipe, a plurality of water spray holes which spray water and drive the water spray pipe to rotate around a center shaft in one direction are formed in the side wall of the water spray pipe, the water spray holes comprise water spray holes a and water spray holes b, the water outlet direction of the water spray holes a deviates to one end of the water spray pipe, and the water outlet direction of the water spray holes b deviates to the other end of the water spraypipe; the water spraying directions of the water spraying holes a and the water spraying holes b are diversified, and ornamental value is achieved. The invention further discloses a spray washing device and a dish washing machine. The nozzle is used for the dish washing machine, the front faces and the back faces of dishes can be flushed at the same time, more positions on the dishes can be directly flushed, and the flushing speed is increased.

Description

technical field [0001] The invention relates to a spraying device, in particular to a spray head. It also relates to spray washing devices and dishwashers. Background technique [0002] Existing tubular nozzles have the following characteristics: the side wall is provided with a water outlet hole that drives the nozzle to rotate around its axis, but the direction of water spraying is basically parallel to the cross section of the nozzle, and the direction of water spraying is single. In the plane where the cross section is parallel, the water column ejected in this way is relatively single, and the ornamental value is not strong. [0003] Some of the same nozzles of the existing spray cleaning devices cannot directly wash the front and back of the object at the same time, and some nozzles rotate in a single direction or can only adjust the angle of the two-dimensional plane, and cannot adjust the angle in the three-dimensional space, so that it cannot be changed flexibly T...
