JP-A-8-189357

  In the combine comprised as mentioned above, the warm air after performing the said heat exchange cools an engine, guiding along the external shape of an engine, and the temperature rises further. The warm air (hot air) diffuses in various directions. For example, when warm air is blown onto an engine bonnet located above the engine, the engine bonnet is warmed, and there is a possibility that the operator in the driving section may feel hot. In particular, in a combine that does not have a cabin and the rear of the engine room is open, the warm air after cooling the engine turns to the rear side of the engine room and flows into the operating section from the engine room. There is also a risk that the pilot may feel hot. This is the same whether it is a water-cooled combine combiner equipped with a radiator or an air-cooled combine combiner not equipped with a radiator.

  An object of the present invention is to provide a comfortable operating environment combine by controlling the wind direction of a blower fan after cooling such as an engine.

According to this configuration, among the warm air after cooling the engine, particularly the warm air that has entered the rear side of the engine is guided downward by the guide member. Therefore, it becomes difficult for hot air to be blown to the engine bonnet, and it is possible to reduce the warming of the engine bonnet by the hot air. As a result, it is possible to reduce the feeling of the driver's feeling hot, and to combine the driving environment with comfort.
In addition, in the case of a combine configured as in this configuration, if no control is made on the direction of the hot air, the hot air will flow backward from the engine room and rise between the operating section and the Glen tank for driving. Will reach the department. However, even with such a combine, if a guide member is provided, it is difficult for hot air to reach the operating section, and thus the driving environment can be kept comfortable.
