Abstract

A showerhead is provided. The showerhead includes a body and a plurality of first dispersion pins. The body has one side having a plurality of injection holes penetrated therethrough and the other side facing the one side. The plurality of first dispersion pins protruding from the plurality of spray holes of the one side to the other side such that end portions thereof support the other side. The first dispersion holes have first gas inlet holes on one side and first passages connected to the first gas inlet holes therein. Gas introduced between the one side and the other side is immediately discharged to the outside of the body through the plurality of spray holes by passing the first gas inlet holes and the first passages.

Claims

1. A showerhead comprising:

a body having one side in which a plurality of injection holes are formed and the other side facing the one side; and

a plurality of dispersion pins respectively protruding from the plurality of injection holes in the one side toward the other side, with one end thereof supporting the other side, each of the plurality of dispersion pins having a gas inlet hole formed in one portion and a passage formed therein, the passage communicating with the gas inlet hole,

wherein gas introduced between the one side and the other side passes through the gas inlet holes and the passages of the plurality of dispersion pins and is subsequently expelled outwardly from the body through the plurality of injection holes.

8. A showerhead assembly comprising a first and a second showerheads arranged in a top-bottom direction, each of the first and second showerheads comprising the showerhead as claimed in claim 1, wherein the first showerheads comprises injection tubes extending downwardly from the injection holes formed in the body thereof, and the second showerheads comprises guide tubes through which the injection tubes of the first showerhead extend in a top-bottom direction.

2. A showerhead comprising:

a body having one side in which a plurality of injection holes are formed and the other side facing the one side; and

a first intermediate plate disposed between the one side and the other side of the body, the first intermediate plate having a first connecting holes; and

a first dispersion pins protruding from the first connecting holes of the first intermediate plate toward the other side of the body, the one end portion of each of the first dispersion pins supporting the other side of the body, each of the first dispersion pins having a first passage formed therein, the first passage communicating with a corresponding first connecting hole among the first connecting holes,

wherein each of the first dispersion pins has a first gas inlet hole in one portion, such that gas introduced between the other side and the first intermediate plate flows through the first gas inlet holes and the first passages, is dispersed between the one side and the first intermediate plate, and subsequently is discharged outwardly from the body through the injection holes.

3. The showerhead according to claim 2, further comprising a second intermediate plate disposed between the first intermediate plate and the other side, wherein the first dispersion pins extend through the second intermediate plate.

4. The showerhead according to claim 3, wherein the first intermediate plate has second connecting holes formed therein,

the showerhead further comprising a second dispersion pins protruding from the second connecting holes toward the second intermediate plate, one end portion of each of the second dispersion pins supporting the second intermediate plate, each of the second dispersion pins having a second passage formed therein, communicating with a corresponding second connecting hole among the second connecting holes,

wherein each of the second dispersion pins has a second gas inlet hole, such that gas introduced between the first intermediate and the second intermediate plate flows through the second gas inlet holes and the second passages, is dispersed between the one side and the first intermediate plate, and subsequently is discharged outwardly from the body through the injection holes.

5. The showerhead according to claim 4, wherein the one side comprises a bottom of an interior space of the body, and the other side comprises a ceiling of the interior space of the body.

6. The showerhead according to claim 4, wherein the first gas inlet holes are formed in end portions of the first dispersion pins, and the second gas inlet holes are formed in end portions of the second dispersion pins.

7. The showerhead according to claim 5, further comprising filler sheets to be brazed on the bottom, predetermined surface of the first and the second intermediate plates facing the ceiling, and upper surface of the ceiling.

9. A showerhead comprising:

a body having one side in which a plurality of injection holes are formed and the other side facing the one side;

a third intermediate plate disposed between the one side and the other side, the third intermediate plate having third connecting holes;

a third dispersion pins protruding from the third connecting holes of the third intermediate plate toward the one side, one end portion of each of the third dispersion pins supporting the one side of the body, each of the third dispersion pins having a third passage formed therein communicating with a corresponding third connecting hole among the third connecting holes,

wherein each of the third dispersion pins has a first gas outlet hole in one portion, such that gas introduced between the other side and the third intermediate plate flows through the third passages and the first gas outlet holes and is subsequently discharged outwardly from the body through the injection holes.

10. The showerhead according to claim 9, further comprising a fourth intermediate plate disposed between the third intermediate plate and the one side, wherein the third dispersion pins extend through the fourth intermediate plate.

11. The showerhead according to claim 10, wherein the fourth intermediate plate has fourth connecting holes,

the showerhead further comprising fourth dispersion pins protruding from the fourth connecting holes toward the one side, one end portion of each of the fourth dispersion pins supports the one side, each of the fourth dispersion pins having a fourth passage formed therein, communicating with a corresponding fourth connecting hole among the fourth connecting holes,

wherein each of the fourth dispersion pins has a second gas outlet hole, wherein gas introduced between the third intermediate plate and the fourth intermediate plate flows through the fourth passages and the fourth gas outlet holes, is dispersed between the fourth intermediate plate and the one side, and is subsequently discharged outwardly from the body through the injection holes, and the gas expelled from the first gas outlet holes is dispersed between the fourth intermediate plate and the one side and is subsequently discharged outwardly from the body through the injection holes.

12. The showerhead according to claim 11, wherein the one side comprises a bottom of an interior space of the body, and the other side comprises a ceiling of the interior space of the body.

13. The showerhead according to claim 11, wherein the first gas outlet holes are formed in end portions of the third dispersion pins, and the second gas outlet holes are formed in end portions of the fourth dispersion pins.

14. The showerhead according to claim 12, further comprising filler sheets to be brazed on the ceiling, predetermined surfaces of the third and fourth intermediate plates facing the bottom, and lower surface of the bottom.

15. A showerhead assembly comprising a third and a fourth showerheads arranged in top-bottom direction, each of the third and fourth showerheads comprising the showerhead as claimed in claim 9, wherein the third showerhead comprises injection tubes extending downwardly from the injection holes formed in the body thereof, and the fourth showerhead comprises guide tubes through which the gas injection tubes of the first showerhead extend in a top-bottom direction.
