Description

원주경사방향으로 회오리 치게 분사되는 세척노즐{Nozzle used for cleaning}Nozzle used for cleaning}

본 발명은 세척노즐에 관한 것으로서, 더욱 상세하게는 노즐에서 분사되는 유체가 회오리 치면서 원주경사방향으로 분사되는 동시에 하부직진방향으로도 회오리 치면서 분사되도록 하여 세척 능률이 크게 향상되도록 개선된 원주경사방향으로 회오리 치게 분사되는 세척노즐에 관한 것이다. The present invention relates to a cleaning nozzle, and more specifically, the fluid sprayed from the nozzle is jetted in the circumferentially inclined direction while whirling, while also being whirled in the lower straight direction, so that the cleaning efficiency is improved so that the cleaning efficiency is greatly improved. It relates to a cleaning nozzle sprayed in a whirlwind.

일반적으로 세척노즐은 노즐 앞쪽에서 한쪽 방향으로만 유체가 토출되도록 된 것이기 때문에 세척되는 범위가 비교적 좁고 한계가 있는 문제점이 있다.In general, since the cleaning nozzle is to discharge the fluid in only one direction from the front of the nozzle, there is a problem that the cleaning range is relatively narrow and limited.

따라서, 선행기술문헌의 특허문헌으로 기재된 바와 같은 회전노즐이 선행기술로 개시되었으며, 이는 노즐헤드가 회전되면서 유체가 분사되도록 세척되는 범위가 상대적으로 넓은 세척범위를 가질 수 있도록 개시된 것이다.Accordingly, a rotary nozzle as described in the patent literature of the prior art document has been disclosed as a prior art, which is disclosed to have a relatively wide washing range in which the nozzle head is rotated so that the fluid is sprayed.

그러나 상기한 선행기술은 노즐헤드가 유체 분사압력으로 노즐헤드가 회전되어야 하는 것이기 때문에 구조가 복잡하고 원가상승이 야기되는 단점이 있을 뿐만 아니라 육안으로 잘 보이지 않는 부분으로 노즐을 삽입하고 세척작업을 하여야 하는 비교적 열악한 세척작업환경에서 세척작업을 할시에는 노즐헤드가 세척물에 접촉되거나 충돌하여 회전하지 못하고 고장 발생률이 높은 문제점을 수반하고 있다.However, the above-described prior art has a disadvantage in that the structure of the structure is complicated and costs are increased because the nozzle head must be rotated by the fluid injection pressure, and the nozzle must be inserted into the part that is not easily seen by the naked eye and washed. When performing a cleaning operation in a relatively poor cleaning environment, the nozzle head does not rotate due to contact or collision with the cleaning material, and has a high failure rate.

본 발명을 첨부된 바람직한 실시도면에 의거하여 보다 상세히 설명하면 다음과 같다.The present invention will be described in more detail on the basis of the attached preferred embodiments.

도 1을 참조하면, 본 발명은 물이나 압축공기를 분사하여 세척되게 하는 세척노즐(10)로서, 일예로서 에어건(G)의 에어분사관(Ga)에 세척노즐(10)을 장착하여 압축공기가 토출되도록 하여 세척되게 하는 것이다.Referring to Figure 1, the present invention is a cleaning nozzle 10 to be washed by spraying water or compressed air, for example, the compressed air by mounting the cleaning nozzle 10 to the air injection pipe (Ga) of the air gun (G) Is to be discharged to be washed.

따라서, 본 발명은 도 2 및 도 3에 나타낸 바와 같이 체결공(11a)이 있는 연결부(11) 및 상기 체결공(11a)과 연통되는 유체공급홈공(13)이 내부에 있는 분사부(12)를 구비하도록 구성된다.Therefore, the present invention, as shown in Figures 2 and 3, the connection portion 11 with a fastening hole (11a) and the fluid supply groove hole 13 communicating with the fastening hole (11a) (13) therein the injection portion (12) It is configured to have.

상기 분사부(12)는 도 2의 (a)에 나타낸 바와 같은 구슬 형태이거나. 또는 도 3의 (a)에 나타낸 바와 같이 원기둥형태 하부가 원뿔형태로 된 것이거나, 또는 도면으로 도시되지는 않았으나 전체가 원기둥 형태인 것일수도 있는 것이다.The injection portion 12 is in the form of a bead as shown in Figure 2 (a). Alternatively, as shown in FIG. 3(a), the lower portion of the cylindrical shape may be a conical shape, or the whole may be of a cylindrical shape, although not illustrated.

이러한 분사 부(12)에는 도 3 (b) 및 도 4 (b)에 나타낸 바와 같이 유체공급홈공(13)과 연통되고 원주면 방향으로 경사지게 구비되는 다수의 원주경사방향경사토출공(14,14',14'')을 갖도록 하되, 상기 원주경사방향경사토출공(14,14',14'')의 내주면에 나선형 회오리생성홈(16)이 각각 형성되도록 구성된다.These injections As shown in Figure 3 (b) and Figure 4 (b) in the part 12, a plurality of circumferential sloping discharge holes 14, 14', which are in communication with the fluid supply groove 13 and are inclined in the circumferential direction 14''), the spiral circumferential grooves 16 are formed on the inner circumferential surfaces of the circumferential inclined discharge holes 14, 14', 14''.

본 발명의 이해를 돕기 위해 세척노즐이 평단면도를 나타낸 도 4를 참조하여 설명하면, 도 4의 (a)는 분사부(12)에 직선방향으로 토출공이 형성되게 한 것으로서, 이러한 직선토출공(h)이 형성되면 유체가 직선방향으로 토출되는 상태가 되는 것이나, 본 발명은 도 4의 (b)와 같이 분사부(12)에 원주경사방향으로 경사지는 경사토출공이 형성되게 한 것이며, 이와 같이 원주경사방향으로 경사지는 토출공이 형성되게 한 것을 본 발명의 이해를 돕기 위해서 원주경사방향경사토출공(14,14',14")이라고 정의하고 설명하는 것으로 하고, 상기와 같이 원주경사방향경사토출공(14,14',14")이 형성되면 그로부터 분사되는 유체가 분사부(12)의 원주경사방향 쪽으로 비스듬한 각도로 분사되는 것이다.To assist the understanding of the present invention, the washing nozzle is described with reference to FIG. 4 showing a flat cross-sectional view, FIG. 4(a) is a discharge hole formed in the linear direction in the injection section 12, such a straight discharge hole ( When h) is formed, the fluid is discharged in the linear direction, but the present invention is such that the inclined discharge hole inclined in the circumferential inclined direction is formed in the injection unit 12 as shown in FIG. To facilitate the understanding of the present invention, a discharge hole inclined in the circumferential direction is defined and described as a circumferential direction inclined discharge hole (14,14', 14"), and the circumferential direction inclined discharge as described above. When the balls 14, 14' and 14" are formed, the fluid injected therefrom is injected at an oblique angle toward the circumferential direction of the injection unit 12.

따라서, 본 발명은 상기와 같은 원주경사방향경사토출공(14,14',14") 내주면에 도 5 및 도 6에 나타낸바와 같은 나선형 회오리생성홈(16)이 더 가공되도록 하여 구성된다.Therefore, the present invention is configured to further process the spiral torsion generating groove 16 as shown in FIGS. 5 and 6 on the inner circumferential surface of the circumferential inclined discharge holes 14, 14', 14" as described above.

그러므로 원주경사방향경사토출공(14,14',14")을 통과하는 유체는 나선형 회오리생성홈(16)으로 들어간 유체가 나선형으로 돌아가면서 통과하는 상태가 되고, 그로 인해 원주경사방향경사토출공(14,14',14")으로 토출되는 유체는 분사부(12)의 원주경사방향 쪽으로 비스듬한 각도로 분사되면서 회오리치는 상태로 분사되는 것이다.Therefore, the fluid passing through the circumferential inclined direction injecting holes 14, 14', 14" becomes a state in which the fluid entering the spiral torsion generating groove 16 passes through the spiral, thereby causing the inclined injecting inclined direction The fluid discharged to (14, 14', 14") is sprayed in a whirlwind state while being injected at an oblique angle toward the circumferential tilt direction of the injection section 12.

상기와 같이 회오리치면서 원주경사방향쪽으로 비스듬한 각도로 유체가 분사되는 원주경사방향경사토출공(14,14',14")들은, 도 2 및 도 3에 나타낸 바와 같이 분사부(12)의 중간 부분의 원주면 방향으로 다수의 원주경사방향경사토출공(14)이 등간격으로 구비될 수 있고, 상기원주경사방향경사토출공(14) 하부쪽 분사부(12)에는 하부쪽을 향하면서 외측방향으로 경사지는 원주경사방향경사토출공(14')이 원주방향으로 등간격으로 구비되도록 구성될수도 있다.As described above, the circumferential sloping direction ejection holes 14, 14', 14" in which the fluid is ejected at an oblique angle toward the circumferential sloping direction are the middle portions of the ejection section 12 as shown in FIGS. 2 and 3 A plurality of circumferential inclined direction inclined discharge holes 14 in the circumferential surface direction of the can be provided at equal intervals, the circumferential inclined discharge hole 14 in the lower injection portion 12 toward the lower side outward direction The sloping circumferential sloping direction discharge hole 14' may be configured to be provided at equal intervals in the circumferential direction.

그리고 상기 원주경사방향경사토출공(14) 상부쪽 분사부(12)에는 상부쪽을 향하면서 외측방향으로 경사지는 원주경사방향경사토출공(14'')이 원주방향으로 등간격으로 더 구비되도록 구성될 수도 있다.In addition, the circumferential sloping sloping discharge hole 14 is further provided with an circumferential sloping sloping discharge hole 14 ″, which is inclined in the outer direction while facing upward, at an equal interval in the circumferential direction. It may be configured.

또한, 분사부(12) 하부에는 나선형 회오리생성홈(16)이 있는 중앙수직토출공(15)이 구비하도록 구성된다.In addition, a central vertical discharge hole 15 having a spiral torsion generating groove 16 is configured to be provided under the injection portion 12.

따라서, 바람직하게는 분사부(12)에는 나선형 회오리생성홈(16)이 있는 원주경사방향경사토출공(14,14')이 분사부(12) 중간 및 하부쪽에 구비되는 동시에 하부에는 나선형 회오리생성홈(16)이 있는 중앙수직토출공(15)이 함께 구비되도록 하는 것이 바람직하고, 필요에 의해서는 상기한 원주경사방향경사토출공(14,14')과 중앙수직토출공(15)을 구비하면서 분사부(12) 상부쪽으로 나선형 회오리생성홈(16)이 있는 원주경사방향경사토출공(14")이 더 구비된 것이 세척노즐(10)로 구성되게 하여 사용되도록 하는 것이 바람직하다.Therefore, preferably, the circumferential sloping direction inclined discharge holes 14 and 14' having a helical torsion generating groove 16 are provided in the middle and the lower part of the blasting section 12 at the same time as the spiral vortex generation in the lower section. It is preferable that the central vertical discharge hole 15 with the groove 16 is provided together, and if necessary, the above-described circumferential tilt direction discharge hole 14, 14' and the central vertical discharge hole 15 are provided. While it is preferable that the circumferential inclined direction inclined discharge hole 14" having a spiral torsion generating groove 16 toward the upper portion of the injection portion 12 is further provided to be used as a cleaning nozzle 10.

따라서, 본 발명은 나선형 회오리생성홈(16)이 있는 원주경사방향경사토출공(14,14',14") 및 나선형 회오리생성홈(16)이 있는 중앙수직토출공(15)으로 각각 토출되어 분사되는 유체가 회오리치면서 토출되는 상태이므로 유체의 분사력에 의해서 유체가 분사되지만 그 분사되는 유체가 물체에 닿게 되는 순간에는 회전력이 물체에 작용되기 때문에 유체 분사력과 회전력이 합쳐진 상태의 타격력으로 물체를 타격하게 되므로 유체 분사력으로만 세척 되었던 예전 보다는 상대적으로 더욱 강한 힘으로 물체를 타격하게 되기 때문에 더욱 양호한 세척작용이 도모된다.Accordingly, the present invention is discharged to the circumferential inclined direction inclined discharge holes (14, 14', 14") with the spiral torsion generating grooves (16) and the central vertical discharge holes (15) with the spiral torsion generating grooves (16), respectively. Since the fluid to be ejected is discharged in a whirlwind, the fluid is ejected by the ejection force of the fluid, but the moment the ejected fluid touches the object, the rotational force acts on the object. Hitting the object with the impact force of the combined fluid ejection force and rotational force Therefore, a better cleaning action is achieved because it hits the object with a relatively stronger force than before, which was only washed with the fluid injection force.

그리고 본 발명은 세척 범위가 더욱 넓어지게 되는 것으로서, 본 발명의 이해를 돕기 위하여 도 7를 참조하여 설명한다.In addition, the present invention will be described with reference to FIG. 7 to help the understanding of the present invention as the washing range becomes more wide.

도 7의 (a)를 참조하면, 예전에 파이프(P)와 같은 제품의 내부공을 세척할 시에는 에어분사관(Ga)을 경사지게 하여 압축공기가 분사되도록 하였으며, 이 경우에는 에어분사관(Ga)을 중앙에 똑바로 있게 한 상태에서 압축공기가 분사되면 파이프(P) 내주면이 잘 세척되지 않으므로 도면에 도시된 바와 같이 에어분사관(Ga)을 경사지게 하여 내주면을 향하도록 하여 세척하였기 때문에 에어분사관(Ga)이 향하는 일부분(Pa)만 세척되었고 그 반대쪽 부분(Pb)은 세척이 미비하거나 아예 세척되지 않는 단점이 야기됨으로써 여러번에 걸처서 세척하여야 하는 문제점이 있었을 뿐만아니라 세척시간도 오래 소요되는 문제점이 야기되었다.Referring to (a) of FIG. 7, when washing the inner hole of a product such as a pipe P, the air injection pipe Ga was inclined to spray compressed air. In this case, the air injection pipe ( Since the inner peripheral surface of the pipe (P) is not cleaned well when the compressed air is injected in a state where Ga) is kept straight in the center, the air injection pipe (Ga) is inclined to face the inner peripheral surface as shown in the drawing, so the air powder is cleaned. Only part (Pa) facing the sergeant (Ga) was washed, and the opposite part (Pb) had a problem of being washed over several times as it caused a disadvantage of insufficient washing or not being cleaned at all, and also a long washing time was required. A problem has arisen.

그러나 본 발명은, 도 7의 (b)에 나타낸 바와 같이 파이프(P) 내부공에 에어분사관(Ga)에 장착된 세척노즐(10)를 정중앙에 똑바로 세워진 상태로 삽입하거나 또는 도면으로 도시된 바와 같이 삐딱하게 경사지게 삽입한 상태이든지간에 그 어떤 삽입상태가 되더라도 파이프(P) 내주면 전체가 세척되는 상태로 작용된다.However, the present invention, as shown in Figure 7 (b), the pipe (P) into the hole inside the air injection pipe (Ga), the cleaning nozzle 10 mounted in a straight upright position in the center or is shown in the figure As described above, regardless of whether it is inserted in an obliquely inclined state, the entire inner circumference of the pipe P is washed even if it is in any inserted state.

즉, 본 발명은 파이프(P) 내부공에 세척노즐(10)이 삽입된 상태에서 세척하게 되면 도 5에 나타낸 바와 같이 원주경사방향경사토출공(14,14')에서 토출되는 압축공기가 회오리치면서 원주경사방향으로 비스듬하게 토출되기 때문에 압축공기는 파이프(P) 내부공의 내주면을 따라 회전되는 상태가 됨으로써 도 7의 (b)에서 화살표 도시와 같이 파이프(P) 내부공의 하부방향으로 회전운동을 하면서 분사되는 상태가 되어서 파이프(P) 내주면 전체를 세척하게 되는 것이고, 이와 더불어서 중앙수직토출공(15)에서 회오리치면서 토출되는 압축공기는 파이프(P) 내주면에서 떨어져 나온 이물질을 하부방향으로 밀어내어 이동시키는 작용을 하게 된다.That is, according to the present invention, when the cleaning nozzle 10 is inserted into the pipe P inner hole, the compressed air discharged from the circumferential direction inclined discharge holes 14 and 14' as shown in FIG. Since it is discharged obliquely in the circumferential direction while striking, the compressed air is rotated along the inner circumferential surface of the inner hole of the pipe (P), thereby rotating in the downward direction of the inner hole of the pipe (P) as shown in the arrow in FIG. In the state of being sprayed while exercising, the entire inner circumferential surface of the pipe (P) is cleaned, and in addition, compressed air discharged while whirling in the central vertical discharge hole (15) discharges foreign matters falling from the inner circumferential surface of the pipe (P) downward. It pushes and moves.

그러므로 본 발명은 파이프(P) 내부공에 에어분사관(Ga)에 장착된 세척노즐(10)를 정중앙에 똑바로 세워진 상태로 삽입하든 아니면 도 7의 (b)와 같이 삐딱하게 경사지게 삽입한 상태이든지간에 그 어떤 삽입상태가 되더라도 파이프(P) 내주면 전체가 세척되는 것이기 때문에 탁월하고 신속 간편한 세척이 도모되는 것이다.Therefore, the present invention is inserted into the inside of the pipe (P), the cleaning nozzle 10 mounted on the air injection pipe (Ga) in an upright state at the center or whether it is inserted in an obliquely inclined shape as shown in Fig. 7(b). Whatever the insertion state of the liver, since the entire inner circumference of the pipe P is cleaned, excellent and quick and easy cleaning is promoted.

도 8은 본 발명의 다른 세척상태를 나타낸 것으로서, 가령 구조가 복잡한 에진(ㄸ)에는 앞면부(Ea)는 외부로 노출되고 뒷면부(Eb)는 외부로 노출되지 않고 옆으로만 개방된 엔진부품이 있고, 이러한 엔진(E)을 세척할 경우에는 예전에는 유체가 직선방향으로만 분사되기 때문에 엔진부품의 앞면부(Ea)만 세척되고 뒷면부(Eb)는 세척할 수 없게 되는 문제점이 있을 뿐만 아니라 노즐이 들어갈 틈이 없는 경우에는 아예 세척할 수 없게 되는 문제점이 야기 되었다.8 shows another washing state of the present invention, for example, an engine part having a complex structure, the front part Ea is exposed to the outside, and the rear part Eb is not exposed to the outside, and is opened only to the side. In this case, when cleaning the engine E, there is a problem in that in the past, only the front part Ea of the engine parts is cleaned and the back part Eb cannot be cleaned because the fluid is injected only in the linear direction. In addition, when there is no gap to enter the nozzle, a problem that cannot be cleaned at all has been caused.

그러나 본 발명은 도 8에서 화살표로 도시된 바와 같이 원주경사방향경사토출공(14,14',14")에서 토출되는 압축공기가 회오리치면서 원주경사방향으로 토출되기 때문에 압축공기가 엔지부품의 옆에 뚫린 부분으로 압축공기가 들어가서 뒷면부(Eb)도 세척할 수 있게 되는 것은 물론이거니와 세척노즐(10)을 삽입할 공간이 없어도 그 주변에 세척노즐(10)을 근접시킨 상태에서 압축공기가 분사되도록 하면 압축공기가 회오리치면서 원주경사방향으로 토출되기 때문에 노즐을 삽입시키지 못한 부분까지도 압축공기가 분사되기 때문에 종래에 세척이 안되었던 부분도 양호하게 세척할 수 있게 되는 것이고, 그로 인해 세척능력이 향상되고 세척범위가 크게 확장되게 넓어지는 것이다.However, in the present invention, the compressed air discharged from the circumferentially sloping discharge holes 14, 14', 14" as shown by the arrows in FIG. 8 whirls, and is discharged in the circumferentially sloping direction. In addition to being able to clean the back portion (Eb) by entering the compressed air into the perforated portion, even if there is no space to insert the cleaning nozzle 10, compressed air is sprayed in the state where the cleaning nozzle 10 is brought around. If possible, the compressed air is discharged in the circumferentially tilting direction while twisting, so that even the part where the nozzle cannot be inserted is sprayed, the previously unwashed part can be cleaned well, thereby improving the washing ability. And the washing range is greatly expanded.

본 발명은 도면으로 도시되고 설명된 것에 반드시 국한되는 것은 아니고 본 발명이 속하는 기술분야의 통상의 지식을 가진 자에 의해서 여러가지 형태로 변형실시될 수도 있는 것이므로 청구범위를 크게 벗어나지 않는한 폭넓게 보호되어야 하는 것은 자명한 것이다.The present invention is not necessarily limited to those illustrated and described in the drawings, and may be modified in various ways by those skilled in the art to which the present invention pertains, and thus should be protected broadly without departing greatly from the claims. It is self-evident.
