Abstract

An apparatus for trapping fumes includes a fume trapping unit including a first flow path for an airflow including fumes to move, a first inlet configured to allow the airflow to flow into the first flow path, and a first outlet configured to discharge the airflow from the first flow path; a cooling unit including a second flow path for refrigerant for cooling the airflow to move, a second inlet configured to allow the refrigerant to flow into the second flow path, and a second outlet configured to discharge the refrigerant from the second flow path; and a pressure sensor configured to measure pressure in the first flow path, wherein the cooling unit is disposed to be in surface-contact with one surface of the fume trapping unit.

First claim

2 . The apparatus of claim 1 ,
wherein the first flow path has a zigzag shape in which a direction of movement of the airflow changes multiple times, and wherein a plurality of: resistors configured to disperse the airflow and to capture the fume are formed in the first flow path.

3 . The apparatus of claim 2 ,
wherein the fume trapping unit includes: a trap body including a lower-surface portion and a first side-surface portion extending upwardly from the lower-surface portion and forming the first flow path; and a trap cover portion disposed in an upper portion of the trap body, and wherein the plurality of resistors include a plurality of irregular columnar bodies extending from the lower-surface portion to a level at which the trap cover portion is installed.

4 . The apparatus of claim 3 ,
wherein the trap cover portion includes: a first trap cover covering an upper portion of the trap body; and a second trap cover disposed on an upper side of the first trap cover and fixed by being coupled to the trap body with the first trap cover interposed therebetween through a fixing member, and wherein the first trap cover and the second trap cover are formed of different materials.

5 . The apparatus of claim 3 ,
wherein the cooling unit includes: a cooling body including an upper-surface portion in surface-contact with the lower-surface portion and a second side-surface portion extending downwardly from the upper-surface portion and forming the second flow path; and a cooling cover portion disposed in a lower portion of the cooling body, wherein the second flow path has a shape corresponding to a shape of the first flow path.

6 . The apparatus of claim 5 ,
wherein the cooling cover portion includes: a first cooling cover for covering a lower portion of the cooling body; and a second cooling cover disposed on a lower side of the first cooling cover and fixed by being coupled to the cooling body with the first cooling cover interposed therebetween through a fixing member, and wherein the first cooling cover and the second cooling cover are formed of different materials.

7 . The apparatus of claim 2 ,
wherein the first flow path includes a buffer region in which the plurality of resistors are not formed, and wherein the pressure sensor measures pressure in the buffer region.

8 . The apparatus of claim 3 ,
