The rotational power of the engine 12 is appropriately reduced by a speed change mechanism in a transmission case (not shown), and transmitted to the front and rear wheels 14 and 15 to travel. A meter panel 17 is provided at the rear of the hood 11. Further, a floor 18 is provided on the upper surface of the central portion of the transmission case, and the rear end of the floor 18 is connected to a pair of fenders 19 that cover the pair of rear wheels 15 from the front to the top. Above the floor 18, a cockpit including a steering wheel 20, a driver's seat 21, an operation lever (not shown), and the like is provided. A sun visor 24 is provided above the cockpit to protect the operator from sunshine and the like. The sun visor 24 is supported by a rope frame 25 provided at the rear end of the fender 19. The rope frame 25 has a U-shape when viewed from the front of the tractor 10 (see FIG. 4), and the sun visor 24 is attached to the center side thereof.

Although not shown, a cabin-type cover may be provided above the cockpit instead of the sun visor 24. At the rear of the main frame 13, a three-point link mechanism 26 (FIG. 4) for connecting a working machine is provided.

An air conditioner unit 30 is attached to the base of the sun visor 24. As shown in a plan view (FIG. 1 (a)) and a side view (FIG. 1 (b)) of the air conditioner unit 30 with the upper lid removed, the arrangement of the condenser 39 and the evaporator 43 and the air paths X, Y A significant feature of the air conditioner unit 30 according to the embodiment of the present invention is that the arrangement has a compact structure.

The air conditioner unit 30 has a substantially rectangular parallelepiped housing 3.
1 is provided with a partition wall 32 that partitions the front and rear rooms, and a partition wall 33 that further partitions the front room into left and right rooms. Therefore, as shown in FIG. 2, the inside of the housing 31 is divided into a front left room A, a front right room B, and a rear room C.

A single electric motor 35 is mounted so as to penetrate the partition wall 33, and axial fans 36 and 37 are mounted on both front (left) and rear (right) shafts. The axial fan 36 is disposed in the room A, and the axial fan 37 is disposed in the room C.
To place. In the room C, a compressor 40 and a freezing thermostat (not shown) for heating the air conditioner during freezing are arranged. Then, the room 31 enters the room C through the opening 31a on the rear wall surface of the housing 31, passes through the room A from the room C via the opening 32a of the partition wall 32, and passes through the opening 31b provided on the left side surface of the housing 31. An air passage X extending to the outside is formed.

The evaporator 43 is disposed along the front side of the housing 31 in the room B. Further, the casing 3 passes through the opening 31c on the right side of the casing 31 and passes through the inside of the room B, and
An air passage Y is provided from the opening 31d on the front surface of the air passage 1 to the outside. The air flowing through the air passage X cools the condenser 39 whose temperature has increased, and discharges the warm air to the outside. Further, since the evaporator 43 is provided at the outlet of the air path Y, it is possible to supply the cool air to the outside of the air conditioner.

Therefore, the condenser 39 and the evaporator 4
By arranging the air conditioner 3 in a narrow space and forming the wind paths X and Y of the condenser 39 and the evaporator 43 in the housing 31, the electric air conditioner of the mobile vehicle can be made compact.

Further, by arranging a single electric motor 35 at a substantially central position of the housing 31 and forming two air paths X and Y, an inexpensive and compact air conditioner can be obtained.

FIG. 4A is a side view of the tractor, and FIG.
As shown in the tractor front view of FIG.
Can be attached to the rising arm 25a of the lops frame 25.

As shown in the plan view of FIG. 5, the interior of the housing 31 is divided into two rooms A, B and C by two partition walls 32 and 33 in substantially the same manner as that shown in FIG. Then, the condenser 39 and the compressor 40 are arranged in the room C, the axial fans 36 and 37 are arranged in the rooms A and B, respectively, and the evaporator 43 is arranged in the room B. Further, a single electric motor 35 is provided so as to penetrate the partition wall 33.
, And axial fans 36 and 37 are attached to both the front (left) axis and the rear (right) axis. The axial fan 36 is arranged in the room A, and the axial fan 37 is arranged in the room C. The air paths X and Y are also provided so as to draw the same trajectory as the air paths X and Y shown in FIG. At this time, unlike the case 31 shown in FIG. 1, the case 31 shown in FIG. 5 is provided with an inclined surface on the right wall surface of the room B, and an opening for introducing an airflow into the passage of the air path Y. 31c is provided. For this reason, the area of the opening 31c on the side wall surface for the air passage Y is larger than that shown in FIG. 1, so that the air flow can easily enter from the opening 31c as compared with the housing 31 shown in FIG. To form the evaporator 4
3 supplies cool air to the outside.

FIG. 6 shows a side view of the housing 31 shown in FIG. 5. Since the upper surface near the axial fans 36 and 37 has a concave shape, the concave portion 31e is formed in the rope frame 25.
, The protrusion of the casing 31 of the air conditioner unit 30 can be reduced.

When the air conditioner unit 30 is disposed on the lower surface of the sun visor 24, the air conditioner unit 30 has the same shape as that shown in FIG. With such a shape, the drop frame 25 can be attached so as to fit into the concave portion 31e, and the installation position of the sun visor 25 does not become unnecessarily high, so that the size can be reduced.

The air conditioner unit 30 may be arranged on the floor 18 of the cockpit as shown in the side view (FIG. 7A) and the plan view (FIG. 7B) of FIG. By arranging the air conditioner unit 30 on the floor 18 of the cockpit, the conditioned air can be blown up from the feet to the operator. Therefore, not only when the cockpit is provided in the cabin, but also in an open space where only the sun visor 24 is used. Even when the air conditioner is provided, air conditioning can be effectively performed.

The air conditioner unit 30 may be disposed on the side of the cockpit floor 18 as shown in the side view (FIG. 8A) and the plan view (FIG. 8B) of FIG. By arranging the air conditioner unit 30 on the side surface of the floor 18 of the cockpit, air conditioning air can be blown up from the feet to the operator. Therefore, not only when the cockpit is provided in the cabin, but also in an open space where only a sun visor is used. When a room is provided, not only can air conditioning be effectively performed, but also the space in the cockpit can be increased.

FIG. 9 is a plan view (FIG. 9 (a)) and a side view (FIG. 9 (b) is a cross section taken along line S1-S1 in FIG. 9 (a)) of the air conditioner unit 30 with the top cover removed. 9 (c) is a cross-sectional view taken along line S2-S2 in FIG. 9 (a)). As shown in FIG. 1, the capacitor 39 and the evaporator 43 are arranged in the same manner as in FIG. A partition wall 32 that partitions the housing 31 into front and rear rooms and a partition wall 33 that further partitions the front room partitioned by the partition wall 32 into left and right rooms are provided. It is divided into room B and room C on the rear side.

An electric motor 35 is mounted on the partition wall 33 in the same manner as shown in FIG. 1, and axial flow fans 36 and 37 are mounted on both front (left) and rear (right) shafts.
6 and 37 are placed in room A and room B respectively.
The rotation direction of the axial fan 36 disposed in the room A is reversed from the example shown in FIG.

Therefore, the room 31 enters the room A through an opening 31b provided on the left side surface of the housing 31, passes through the room C from the room C via the opening 32a of the partition wall 32, and opens on the rear surface of the housing 31. An air passage Z extending from the portion 31a to the outside is formed.
Note that the other axial fan 37 disposed in the room B is the same as that in FIG.
As shown in FIG. 1, the opening 31d on the front side of the housing 31 passes through the inside of the room B from the opening 31c on the right side of the housing 31 as in the case shown in FIG.
An air passage Y communicating with the outside is formed.

In the example shown in FIG. 1, the wind flowing through the air path X becomes warm air heated by the condenser 39 and is discharged outside through the opening 31b provided on the left side surface of the housing 31.
Since the outlet position of the warm air (opening 31b) and the outlet position of the cool air (opening 31d) are relatively close, the cool air cooled by the evaporator 43 and the warm air after cooling the condenser 39 are blown from the same direction. For example, it is necessary to regulate the flow of the wind by using, for example, an extended duct for blowing out hot air.

However, in the example shown in FIG.
Since the warm air warmed by the air exits the housing 31 through the opening 31a on the side wall surface, the warm air discharged from the air passage Z and the cool air discharged from the air passage Y are transmitted from opposite sides of the housing 31. As a result, the hot air and the cold air are not mixed outside the housing 31.
