Figure 11 observes the block diagram driving chamber 31 from bottom.As shown in figure 11, the part on the floor 35 near cover 33 place of driving chamber 31, the gap between operator's compartment outer panel 36 and operator's compartment interior plate 37 is formed as the air suctiton inlet 34 for importing outer gas.In addition, in the end of a side of cover 33, in order to the open-close lid parts 33 when safeguarding, the hinge 33a that can be supported rotationally by cover 33 is installed.

Figure 12 is the cutaway view of the XII-XII line along Figure 10.As shown in figure 12, on the surface of a side of driving chamber 31, opening and closing is provided with cover 33 freely.The outer gas introduction part 38 be connected with air suctiton inlet 34 is formed in the inside of cover 33.In addition, the downstream of gas introduction part 38 is provided with filter 39 outside.Filter 39 is connected with air-conditioning unit 41 via outer gas ingress pipe 40.The clean air after air regulation is sent into the inside of driving chamber 31 from the air outlet 42a of the pipe 42 being configured in air-conditioning unit 41 rear portion.Air-conditioning unit 41 loads and is fixed on the floor 35 of driving chamber 31.

Figure 13 is the enlarged drawing of the periphery representing cover 33 in detail.Cover 33 can be arranged on rotationally drive chamber 31 surface on the operator's compartment outer panel 36 fixed.At the rear portion (downstream) of cover 33, be formed with the outer gas introduction part 38 of being surrounded by operator's compartment outer panel 36 and operator's compartment interior plate 37.Filter 39 is configured with at the rear portion of the peristome of operator's compartment interior plate 37.The back side of filter 39 is connected with air-conditioning unit 41 via outer gas ingress pipe 40.

By above structure, the path shown in arrow F that the suction pathway of outer gas is Figure 13.That is, outer gas imports from the air suctiton inlet 34 of the bottom on floor 35, is guided by filter 39 by the space (outer gas introduction part 38) between operator's compartment outer panel 36 and operator's compartment interior plate 37.Air-conditioning unit 41 is supplied to by outer gas ingress pipe 40 by the outer gas of filter 39.The air having carried out air regulation by air-conditioning unit 41 is as shown in figure 12 from the air outlet 42a of pipe 42 to the internal feed driving chamber 31.In addition, the suction pathway of the pipe of the upstream side of air suctiton inlet 34 is formed straight near the swing type mechanism 12 of operator's compartment 14 bottom shown in Fig. 8 (direct), and the pipe of suction pathway shortens.In addition, outer gas is directed into the bottom on floor 35 from the gap formed between backplate 13a and operator's compartment outer panel 36.

Figure 14 is the block diagram of the cover 33 shown in Figure 13 and filter 39.Indicate the path that the path importing outer gas from air suctiton inlet 34 and the water tegmentum parts 33 caused because of carwash and rainfall block in fig. 14.The outer gas imported by the air suctiton inlet 34 on floor 35 is guided to filter 39 by the outer gas introduction part 38 of being surrounded by operator's compartment outer panel 36 and operator's compartment interior plate 37 as shown by arrow G.On the other hand, the water caused because of carwash and rainfall clashes into cover 33 as shown by arrow H and becomes water droplet P, and water droplet P falls downwards along cover 33.Thus, prevent the water that causes because of carwash and rainfall to import and filter 39 soaks to filter 39.

As mentioned above, in the present embodiment, in the interior environment system of the operator's compartment on the construction machinery and equipment such as hydraulic actuated excavator of conditioning unit with outer gas introducing-type, the cover 33 be opened when carrying out the upkeep operation of the filter 39 filtering outer gas is arranged on the side of operator's compartment 14.Cover 33 is configured to, and in order to prevent filter 39 from soaking due to the water caused because of carwash and rainfall, being set to blind plate, and can passing through hinge opening and closing as required.In addition, the peristome of maintenance closed of tegmentum parts 33 is connected to filter 39 by the outer gas introduction part 38 formed in the space between operator's compartment interior plate 37 that operator's compartment 14 is formed and operator's compartment outer panel 36.In addition, under the space of outer gas introduction part 38 is communicated to the base plate of the operator's compartment 14 be positioned at below filter 39, and air suctiton inlet 34 is formed at this.Thereby, it is possible to from air suctiton inlet 34 to gas the internal feed of interior environment system.Therefore, only import gas from air suctiton inlet 34, moisture can not be imported into filter 39.

In addition, in the interior environment system of present embodiment, because air suctiton inlet 34 is under bottom plate of driving cab, therefore, it is possible to prevent the water of carwash and rainfall from immersing in the space of outer gas introduction part 38.Thus, can more effectively prevent filter 39 from soaking.

In addition, cover 33 and filter 39 are set to shape similar, and make the area of the opening closed by cover 33 be greater than the area of filter 39, thus can more easily change filter 39 when opening cover 33.In the present embodiment, illustrate the example that cover 33 uses blind plate, but if do not form opening in the opposed locations of filter 39, then also can combine the part of blind plate and opening portion and form cover 33.In addition, in the present embodiment, illustrate the example forming downward air suctiton inlet 34, but as shown in Figure 17 described later, also can be formed towards the rear of operator's compartment 14.

As mentioned above, in existing interior environment system, the cover being arranged at the sidepiece of operator's compartment is had both as the function of the lid for safeguarding the filter filtering outer gas and the function for being carried out air-breathing by opening set on cover.Therefore, there is the possibility that above-mentioned filter soaks due to the water caused because of carwash and rainfall.Therefore, as its countermeasure, immersion is installed and prevents with shield, or the part of blind plate is set to make the opposed locations of opening and filter offset on cover, thus prevent filter from soaking.Its result, comprises the complex structure of the periphery of cover and maximizes, becoming the major cause that interior environment system cost uprises.

Therefore, in the interior environment system of present embodiment, replace not arranging opening on the cover for maintenance filter, air suctiton inlet set from the floor of the bottom surface of operator's compartment sucks outer gas, thus prevents filter from soaking.In other words, make cover only have the function of the lid as the opening closed for maintenance filter, the air suctiton inlet then set from the floor of the bottom surface of operator's compartment towards the air-breathing of interior environment system carries out.By this structure, do not increase extra parts just can realize outer gas importing with low cost, and can prevent filter from soaking.In addition, the maintenance of filter can also easily be implemented.

In addition, because the filter opposed locations at cover does not form opening, therefore, it is possible to prevent filter from soaking effectively, therefore, it is possible to prevent effectively due to filter immersion and the hydraulic performance decline of air-conditioning unit and the lost of life etc. of filter occur.In addition, also do not need setting to prevent with shield for the immersion preventing filter from soaking, and do not need cover is maximized, therefore, it is possible to prevent the cost of interior environment system from increasing.

In addition, because cover does not have opening, therefore the outward appearance of operator's compartment is also attractive in appearance, and the degree of freedom of the design of operator's compartment also improves.In addition, bottom surface due to the operator's compartment below filter has opening (air suctiton inlet), therefore invade dust in the space between operator's compartment outer panel and operator's compartment interior plate and moisture is discharged automatically, therefore the spatter property of interior environment system improves further.In addition, due to the possibility not having filter to suck dust and the moisture invaded from the air suctiton inlet of the bottom surface of operator's compartment, therefore the life-span of filter extends further, and can reduce over the maintenance times of filter.
