[Effect of device]

 When working on a hydraulic excavator, the temperature inside the driver's cab changes according to the climate and weather, and the surface temperature of each part of the driver's body also changes. In the conventional technology, most of the cool air from the air conditioner is blown out obliquely upward from the rear side of the driver's seat. Since the main flow of cold air is blocked by the backrest of the driver's seat and the driver cannot directly and effectively receive cold air (or warm air), the environment inside the driver's cab cannot be said to be comfortable. However, in the ventilation pipe device for air conditioning of the present invention, the ventilation pipe that communicates with the air conditioner unit is installed on the side of the driver's seat integrally with the seat part of the driver's seat or on the side of the driver's seat. It was installed on the column, and the height of the air outlet of the ventilation pipe was set to the height position of the upper body part when the driver was seated. As a result, the cool or warm air from the air conditioner passes through the ventilation pipes installed on the stanchions and is blown out from the air outlet to the upper body of the driver. Therefore, when the temperature of the upper body of the driver rises due to strong sunlight, or when the temperature of the upper body of the driver decreases due to severe cold, cold air or warm air can be effectively received. Also, in the ventilation pipe device for air conditioning, in which the pillars are formed integrally with the seat part of the driver's seat, the cool air or warm air blown out from the outlet of the ventilation pipe will not affect the upper half of the driver's body regardless of the front-back adjustment of the seat part. It is convenient because it is blown out. In addition, since the monitor cluster gauge and the outlet of the ventilation pipe are arranged side by side on the above-mentioned pillar, the driver's operation is convenient, and at the same time, there is economical efficiency of two birds with one stone in the manufacture of the pillar.
