Title:
PAINT DRYING OVEN
Document Type and Number:
WIPO Patent Application WO/1997/012691
Kind Code:
A1
Abstract:
A paint drying oven for baking a paint film of a painted article for drying following a painting process. In a combustion type heating device for use in a conventional oven, combustion gas still holding a great quantity of heat which has just its heat exchanged with circulating air in an in-oven circulation air path is discharged outside the system, thus causing a great heat loss. In the present invention, air (PA) sent out from an air path (ip) inside a radiation means (7) is branched off a location of a radiating circulation air path (20) upstream of a connecting point of a fresh air path (18a) with the radiating circulation air path (20) and a branch air path (21) is provided for mixing this branched-off air (PA") with circulation air (RA) in an in-oven circulation air path (9a). Thus, the provision of this branch air path (21) can make it possible for a radiating combustion type heating device (19a) to function also as an in-oven heating means (Ha), and therefore the problem inherent in the prior art can be solved.
