BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cab-over type refrigerating vehicle.

[0002]

2. Description of the Related Art Conventionally, a cab-over type freezing vehicle has a cab-over type driver's seat at the front of a chassis, a luggage storage room mounted on a rear chassis, and an evaporator case provided at an upper portion of a front wall of the storage room. This was projected above the driver's seat, and the evaporator built in the case was supported on the ceiling side as shown in FIG.

In such a refrigerator car, the driver's seat cannot be tilted forward unless the space between the driver's seat and the front wall of the luggage compartment is widened. In other words, the center of gravity slightly moves rearward, so that the driver is difficult to drive, and the traveling case does not smoothly flow the wind due to an increase in air resistance due to the protruding case. Further, if the shape of the driver's seat is changed depending on the type during manufacturing, interference occurs between the protruding case and the driver's seat, so that there is a problem that the luggage storage room must be shifted backward.

[0004]

[Problems to be Solved by the Invention] In the present invention, since the space between the driver's seat and the luggage storage room is short, the overall length of the car is short (it is hard to be limited by the length), and the driver can move the center of gravity slightly forward and drive. It is an object of the present invention to provide a refrigerating vehicle that is easy to operate, has low air resistance during running, and is not affected by a change in the type of a driver's seat (cab).

[0005]

In order to achieve the above object, the present invention mounts a luggage storage room on a chassis, forms a widthwise long opening in an upper portion of a front wall of the storage room, and forms the opening. In a refrigerator car closed with an evaporator case and supporting the evaporator inside the case, the evaporator case is formed by a relatively flat front bulging heat insulating plate, and the upper end of the front surface of the heat insulating plate is connected to the upper surface of the front end of the ceiling, The lower end of the front is connected to the front of the front wall, and the inside of the
A porator support plate is provided, and upper and lower ends of the support plate and the opening

And a refrigerating vehicle provided with an inclined downward ventilation space .

[0006]

In the present invention, the evaporator 10 is operated by operating a refrigerating unit such as a compressor and a condenser provided on the chassis 9 side, and air is blown under the floor 12 by a blower 10 'provided at the upper end of the evaporator 10. Through the air passage t on the inner surface of the front wall 3 and the evaporator 1
0 to cool the air and circulate it from the lower surface of the ceiling wall 11 to the ventilation path below the floor surface 12 or in the opposite direction, thereby cooling the interior of the luggage storage room 7.

In this state, the driver drives in the driver's seat 8 to move the chassis 9 to the destination. During traveling, the evaporator case 1 is relatively flat and the front surface bulges, the upper end is connected to the upper surface of the front end of the ceiling, and the lower end of the front surface is connected to the front surface of the front wall 3, so that the air resistance is reduced and the accommodation room is reduced. The wind smoothly flows from the front surface of the front wall 3 to the upper surface and the left and right sides of the ceiling wall 11.

Since the evaporator 10 is thin, the evaporator 10 can be accommodated in the opening 4 of the front wall 3 long in the left-right direction and vertically, and can be supported on the flat inner surface of the heat insulating plate 2. It is accommodated without protruding to the rear side of the evaporator support plate 5 provided on the inner surface and the ventilation path t along the inner surface of the front wall 3.

The heat insulating plate 2 bulges forward but is relatively flat, so that the space T between the front surface of the front wall 3 and the rear surface of the driver's seat 8 can be kept small, and the entire luggage storage room 7 can be kept. To the driver's seat 8 side and mounted on the chassis 9. Therefore, the entire length of the vehicle is reduced, and the center of gravity can be slightly moved forward.

Although the shape of the driver's seat 8 differs depending on the type of the vehicle, the mounting position of the accommodation room 7 does not need to be changed one by one because the front bulging heat insulating plate 2 is relatively flat.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A box-shaped luggage storage room 7 is mounted on a cab-over type chassis 9 having a driver's seat 8 capable of leaning forward at the front.
The accommodation room 7 has a front wall 3, a ceiling wall 11, left and right side walls 13,
13 and a floor wall, and a heat insulating door is provided at the rear end, and each of the walls 3, 11, 13, 13 is insulated by a heat insulating material. It is also possible to provide a door on the side wall 13.

A rectangular opening 4 which is long in the width direction is formed in the upper part of the front wall 3, and the opening 4 is closed by the evaporator case 1. Inside the case 1, an evaporator 10 is provided.
And a refrigerator car is formed.

The evaporator case 1 is formed by a relatively flat front bulging heat insulating plate 2, the center of the FRP front plate 2 'bulges forward, and the upper, lower, left and right portions become inclined rearward. , 14 ′, the upper edge flange 14 is connected to the upper surface of the ceiling wall 11 by bolts 15, the lower edge and both right and left side edge flanges 14 ′ are connected to the front surface of the front wall 3 by bolts 15, and the urethane foam 2 is internally provided. To form the heat insulating plate 2.

On the inner surface of the heat insulating plate 2, evaporator support plates 5, 5, 5 are provided vertically, and a ventilation guide plate for connecting upper and lower ends of the support plates 5, 5, 5 and upper and lower ends of the opening 4. 6,
6 'and mounting plates 6 ", 6" connecting the left and right ends of the left and right support plates 5, 5 and the left and right inner ends of the opening 4 are provided, and are relatively thin in the front-rear direction (in the direction perpendicular to the width direction). The front of the box 10 ″ of the thin evaporator 10 is connected to the support plates 5, 5, 5
In this manner, the evaporator 10 can be arranged with the main body in the interior surrounded by the inner peripheral surface of the opening 4.

The rear surface of the evaporator 10 is held at the front portion of the rear surface of the ventilation passage t along the inner surface of the front wall 3, and the ventilation passage t is provided between the vertical ventilation guide ridges provided on the inner surface of the front wall 3. 1 or in the blocking plate 16 shown in FIG. In the figure, reference numeral 17 denotes a drain hopper provided on the evaporator 10, reference numeral 18 denotes a supporting square member of the heat insulating plate 2 erected in the left-right direction at the front end of the ceiling wall 11, reference numeral 19 denotes a supporting profile, and reference numeral 20 denotes a supporting member.
Is a supporting square member provided at the lower edge of the opening 4, and 21 is a supporting profile member.

According to the present invention, the space T between the front surface of the front wall 3 of the luggage compartment 7 and the rear surface of the driver's seat 8 is constructed as described above.
The storage chamber 7 can be moved slightly forward to mount it, and the center of gravity can be moved slightly forward, so that the driver can easily drive, reduce air resistance during traveling, and cut off the wind smoothly. be able to.

Further, there is an advantage that the position of the luggage storage room 7 in the front-rear direction can be designed without being affected by a change in the shape of the driver's seat 8 due to a difference in vehicle type.
