The present invention relates to a smoke exhaust device.

The duct discharges indoor polluted air to the outside, or supplies fresh outside air to the room. Such a duct is installed on the ceiling, and a smoke discharge device is installed in the duct for sucking smoke generated from the roasting device.

The smoke evacuation device includes a connecting pipe, a fixed pipe, a movable pipe and a lifting unit. The connecting pipe is connected to the duct, the fixed pipe extends the connecting pipe, and the processed pipe is coupled to be able to elevate the fixed pipe in close proximity to the roasted material. The movable pipe moves up and down according to the roasting state, so that the roasting material and its spacing are adjusted. The elevating unit fixes the elevating position while controlling the movable tube to elevate.

The lifting unit is composed of a ball or roller, wire, coil spring, etc., which is coupled to the movable tube and elastically close to the connecting tube with the elastic force of the spring, and is disposed on the connecting tube and includes a reel connected to the movable tube. .

The conventional lifting unit using a reel is Republic of Korea Utility Model Registration No. 20-0359943 (August 16, 2004) (Quote 1), Korea Patent Registration No. 10-0908695 (July 14, 2009) (Quote 2 ) And the Republic of Korea Patent Publication No. 10-2013-0002855 (2013. 01. 08.) (citation reference 3) and the like is a well-known technique.

[Quotation 1] installed a bracket on the outside of the connector and a reel including rollers, wires, and coil springs on the brackets. The wire is connected to the movable tube. When the movable pipe is elevating, a through hole is formed in the connecting pipe so that the elevating center is located at the center of the movable pipe, and the wire is inserted from the outside of the connecting pipe into the inside through the through hole. Then, the wire inserted into the connecting pipe was placed in the center of the moving pipe elevating through a guide installed in the connecting pipe, and then connected to the moving pipe.

However, as the through-hole is formed in the connection pipe, a problem occurs in that smoke flowing through the inside of the movable pipe, the fixed pipe, and the connection pipe is discharged into the room through the through-hole, thereby reducing reliability. In addition, when the guides, wires, etc. are damaged, the movable pipes, fixed pipes, and connecting pipes are separated and repaired, thereby reducing maintenance work and increasing time and maintenance costs.

[Quotation 2] and [Quotation 3] are connected to the processing pipe by placing the reel inside the connecting pipe and then placing the wire in the center of the moving pipe lifting. In this case, since a hole through which the wire penetrates is not formed in the connecting pipe, smoke flowing through the movable pipe, the fixed pipe, and the connecting pipe is not introduced into the room. However, as the reel was placed inside the connector, it interfered with the flow of smoke. As the reel was directly exposed to flowing smoke, the oil contained in the smoke adhered to wires, rollers, etc., so that the movement of the wire was not smooth. In addition, when the reel was damaged, the connecting pipe, fixed pipe, and movable pipe had to be separated as a whole.
