Housing assembly and surveillance camera apparatus including the same
View Patent ↗A housing assembly and a surveillance camera apparatus including the housing assembly are provided. The housing assembly includes a dome cover which receives a photographing component therein; an air blower which provides air to the dome cover; and a duct through which the air provided from the air blower is discharged to the dome cover.
1. A housing assembly comprising:
a cover which receives a photographing component therein;
an air blower which provides air to the cover; and
a duct through which the air provided from the air blower is discharged to the cover,
wherein the duct has a width that is gradually increased from an end to another end, and comprises an exhaust hole, through which the air is discharged to the cover, at around the other end and adjacent to the cover,
wherein the duct comprises a single duct.
2. The housing assembly of claim 1 , further comprising a heater which heats the air provided from the air blower.
3. The housing assembly of claim 1 , further comprising a heater that is adjacent to the air blower,
wherein the air blower draws in the air heated by the heater and provides the heated air to the duct.
4. The housing assembly of claim 1 , wherein the cover is a dome cover.
5. The housing assembly of claim 4 ,
wherein the dome cover is a hemisphere and the exhaust hole is formed as an arc curved along a circumference of the dome cover.
6. The housing assembly of claim 5 , wherein, an arc length of the exhaust hole is equivalent to or larger than 0.25 times the circumference of the dome cover.
7. The housing assembly of claim 4 ,
wherein the dome cover is a hemisphere and the exhaust hole is formed as an arc curved along a circumference of the dome cover, and an arc length of the exhaust hole is 0.25 times to 0.5 times the circumference of the dome cover.
8. The housing assembly of claim 1 , wherein the exhaust hole is formed toward the cover so that the air discharged through the exhaust hole flows along an inner surface of the cover disposed on a lower portion of the housing assembly.
9. The housing assembly of claim 1 , wherein the duct comprising an inlet hole at the end and an exhaust hole at the another end, and
wherein the air blower is connected to the inlet hole and the air is discharged to the cover through the exhaust hole provided adjacent to the cover.
10. A housing assembly comprising:
an air blower which generates and provides a flow of air to a dome cover which is configured to receive a photographing component therein;
a heater heating the air provided from the air blower; and
a duct comprising an exhaust hole through which the air flow provided from the air blower is discharged to the dome cover,
wherein the exhaust hole of the duct is disposed adjacent to the dome cover, wherein the duct has a width that is gradually increased from an end portion to another portion, and
wherein the exhaust hole is disposed at the another portion,
wherein the housing assembly includes only a single duct.
11. The housing assembly of claim 10 , the heater is received in the duct.
12. The housing assembly of claim 10 , wherein the duct comprises a metal.
13. The housing assembly of claim 10 , wherein the exhaust hole is curved along a circumference of the dome cover.
14. The housing assembly of claim 13 , wherein the dome cover is hemispherical and the exhaust hole is formed as an arc curved along the circumference of the dome cover, and an arc length of the exhaust hole is equivalent to or larger than 0.25 times the circumference of the dome cover.
15. The housing assembly of claim 13 , wherein the dome cover is hemispherical and the exhaust hole is formed as an arc curved along the circumference of the dome cover, and an arc length of the exhaust hole is 0.25 times to 0.5 times the circumference of the dome cover.
16. The housing assembly of claim 10 , further comprising an inner case which guides the air discharged through the exhaust hole to flow along an inner surface of the dome cover disposed under the housing assembly, and has an outer diameter that is less than an inner diameter of the dome cover.
17. The housing assembly of claim 16 , wherein an end portion of the inner case extends past the duct toward the cover.
18. The housing assembly of claim 17 , wherein the end portion faces an part of the dome cover.
19. The housing assembly of claim 10 , wherein the duct further comprises an inlet hole on which the air blower connects to the duct.
