Abstract
To obviate the need for complex adjustments or control arrangements and to obtain a high rate of air flow therethrough, a spiral box for a fume escape hood (e.g. for removing fumes from a kitchen) comprises a housing 6 having a front wall 7 and a rear wall 4 between two adjacent ends of which extends an oblique wall 2. A fan is fastened on the front wall 7. The rear wall has an inlet ring 1 of diameter D1 and the front wall has at opposite ends thereof respectively a rectangular outlet for recirculated air A, and a circular outlet for exhaust air C. A conical wall portion 3 extends obliquely from the rear wall adjacent one end thereof and forms part of a ring edge 10 having a diameter d and through which exhaust air B can escape. One edge 8 of the front wall is, above abscissae axis x, curved at 11 toward the ring edge 10. The other edge 12 of the front wall has, also above axis x, two curved portions 14, and 15 which are flush with and extend from respective ends of a curved portion 16.
