Abstract

PURPOSE:To increase the intake quantity of outside air and to improve the ventilation performance by constituting so that the outside air is introduced through the upper rear portion of a cabin below a roof and guided into the cabin through a filter member provided at the back of the roof in a tractor or the like. CONSTITUTION:When an inflow port 7a is closed with a shutter 11 by means of an operation lever not shown in the figure, outside air is introduced through an outside air inlet 4 provided on an upper rear frame 3 below a roof 5 and guided into an air conditioner 17 through a chamber 8, filter member 10, and duct 6, then it is air-conditioned and discharged into a room. When the inflow port 7a is opened and an intake 18 is closed, no outside air is introduced, and the air in the room 9 is circulated through the inflow port 7a, chamber 8, filter member 10, duct 6, air conditioner 17, and room 9. According to this constitution, the vertical thickness of the upper rear frame 3 which is larger than the thickness of the roof 5 can be utilized for introducing the outside air, thus sufficient outside air can be introduced and the ventilation performance can be improved.

る。Conventional ventilation systems have an outside air intake duct (ffill) placed between the ceiling of the cabin and the back of the cabin, and an outside air intake port (11 and 11 degrees thicker in the vertical direction) into this outside air intake duct. A structure that allows 1 ts of outside air to enter is generally used.

いる。However, recently, mainly from the viewpoint of improving the appearance, cabins with the thickness of this rock as thin as possible are being used, so the outside air intake port has to be made smaller, and as a result, the number of direct air intakes is reduced. As a result, ventilation has deteriorated.
