Abstract:
The purpose of the present invention is to provide a work machine capable of blowing, from an outlet of a duct, air-conditioned air in which cold air and warm air generated by an air-conditioner body are sufficiently mixed. A work machine (1) according to the present invention comprises: a machine body (2); a cabin (5) mounted on the machine body (2); a driver's seat (6) disposed inside the cabin (5); an air-conditioner body (29) for generating air-conditioned air to be supplied into the cabin (5); and a duct structure (50) through which the air-conditioned air supplied from the air-conditioner body (29) is guided. The air-conditioner body (29) mixes cold air and warm air to generate air-conditioned air for cooling and heating purposes. The duct structure (50) has: a first duct (53) that allows the air-conditioned air for cooling purpose to circulate therethrough; a second duct (54) that allows the air-conditioned air for heating purpose to circulate therethrough; a switching box (52) that is connected to the first duct (53) and the second duct (54), and that is capable of switching between a first state, in which the air-conditioned air supplied from the air-conditioner body (29) is circulated through the first duct (53), and a second state, in which said air-conditioned air is circulated through the second duct (54); and a relay duct (51) that connects between the air-conditioner body (29) and the switching box (52) and guides the air-conditioned air generated by the air-conditioner body (29) to the switching box (52).
