Title:
INTAKE AIR COLLAR AND EXHAUST COLLAR FOR COMBUSTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/105792
Kind Code:
A1
Abstract:
The present invention relates to an intake air collar and an exhaust collar for a combustion device, and more particularly, to an intake air collar and an exhaust collar for a combustion device, wherein the intake air collar and exhaust collar mounted on the intake air portion and exhaust portion of a combustion device such as a boiler, a hot-water supply device, or the like, are doubly constructed so that flue pipes of various types and diameters can be mounted thereon. The present invention comprises: a first insertion portion configured to allow a first pipe to be inserted thereinside; a second insertion portion configured to allow a second pipe to be inserted onto the outside of the first insertion portion; and an insertion limitation portion which is integrally formed on the lower surfaces of the first and second insertion portions, and protrudes outward at a predetermined length while forming a boundary with an insertion portion coupled with a housing of the combustion device. According to the an intake air collar and an exhaust collar for a combustion device of the present invention, the diameters of the intake air collar and exhaust collar are different from each other, and thus it is possible to simultaneously connect and use 2-inch and 3-inch pipes, so that the intake air collar and exhaust collar can be directly applied without replacement of the intake air collar and exhaust collar when an intake air collar and an exhaust collar, which are relatively longer than a normal intake air collar and a normal exhaust collar, are mounted on a combustion device, thereby reducing work hours and cost. In addition, since both a PVC pipe and a PP pipe can be mounted, application is possible regardless of the country.
