Fun unit

摘要

The invention relates to a fan unit (1) for mobile use for ventilating an area in which it is deployed, in particular for circulating fresh air in areas contaminated by smoke or gases, which comprises a main frame (2), having a lifting frame (4) mounted thereon and an axial fan (3). A first pivot arrangement (8) for the lifting frame (4) is disposed on the one hand in the region of a frame part (7) extending up from a base frame (6) and on the other hand in a first end region (14) of the lifting frame (4) facing the frame part (7). The lifting frame (4) can be adjusted in terms of its vertical distance from the base frame (6) from a non-operating position lying closer thereto into a raised deployment position. A second pivot arrangement (17) is disposed on the lifting frame (4) about which a support frame (19) is mounted so as to be pivotable in terms of its relative position with respect to the base frame (6). The axial fan (3) is retained on the lifting frame (4) with the support frame (19) connected in between.

1. Fan unit (1) for mobile use for ventilating an area in which it is deployed, in particular for circulating fresh air in areas contaminated by smoke or gases, comprising
a main frame (12) having a base frame (6) which can be positioned facing a support surface (5) and at least one rear frame part (7) extending up from the base frame (6), a lifting frame (4), which lifting frame (4) is mounted on the main frame (2) so as to be pivotable about a first pivot axis (9) of a first pivot arrangement (8) extending in the horizontal direction, and an axial fan (3) having a drive unit (10), a fan wheel connected thereto in a driving arrangement, and a fan housing (11) accommodating the fan wheel, which axial fan (3) is retained on the lifting frame (4), wherein the first pivot arrangement (8) for the lifting frame (4) is disposed on the one hand in the region of the frame part (7) extending up from the base frame (6) and on the other hand in a first end region (14) of the lifting frame (4) facing the rear frame part (7), and the lifting frame (4) is designed so that it projects out from the rear frame part (7) in the direction towards a front face, and a second end region (15) of the lifting frame (4) spaced apart from the first end region (14) can be adjusted in terms of its vertical distance from the base frame (6) from a non-operating position lying closer to the base frame (6) into a deployment position raised relative thereto, and a second pivot arrangement (17) with a second pivot axis (18) is disposed on the lifting frame (4), which second pivot arrangement (17) is disposed at a distance apart from the first pivot arrangement (8), and a support frame (19) is mounted on the lifting frame (4) so as to be pivotable in terms of its relative position with respect to the base frame (6) about the second pivot axis (18) of the second pivot arrangement (17), thereby enabling an inclination of the air flow generated by the axial fan (3) to be adjusted, and the axial fan (3) is retained on the lifting frame (4) with the support frame (19) connected in between.
