Description

[Detailed Description of the Invention] The present invention relates to a pan-wagon type vehicle cooling device.

Conventional cooling systems of this type have a cooling unit installed behind the passenger seat or driver seat, but there are concerns about the safety of passengers sitting in passenger seats located behind these seats. The noise caused by the rotation of the air blower fan of the cooling unit easily enters the passenger compartment and is unpleasant.

In view of the above points, this invention focuses on the fact that there is a header panel that covers the engine between the passenger seat, driver seat, and the passenger seat behind it, and the cooling unit is installed inside this header panel. and a duct for discharging cold air connected to this cooling unit is housed inside the side wall of the passenger compartment,
By connecting a ceiling duct with a cold air outlet attached to the ceiling of the passenger compartment to the above duct, it is possible to ensure the safety of the occupants, and also to prevent noise from the cooling unit from entering the passenger compartment as much as possible. The purpose of the present invention is to provide a cooling device for a pan-wagon type vehicle.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

In FIGS. 1 to 5, reference numeral 1 denotes a cooling unit, which includes an electric motor 1a, a blower fan 1b, a cooling heat exchanger 1C1, and a resin case 1d that houses these.

This case 1d is provided with a vehicle interior air suction port 1e and a fan casing portion 1f.

Reference numeral 2 denotes a header panel (made of metal plate), which is located between the driver's seat 3 and passenger seat 4 and the passenger seat 5 behind them, and covers the engine 6.

An opening 2a is provided on the upper surface of the header panel 2 on the passenger compartment side.
is provided, and the cooling unit 1 is disposed inside the header panel 2 through this opening 2a.

The case 1d of the cooling unit 1 includes a bracket 7 welded and fixed to the header panel 2 and a front wheel 8 of the vehicle.
It is fixed with screws to the bracket 9 which is welded and fixed to the mudguard part of the body.

The cooling unit 1 is separated from the engine 6 by a partition plate 26 welded to a vehicle body frame 25.

10 is a resin suction grill, and this suction grill 10
is attached to the suction port 1e of the cooling unit 1 through the suction port 2b of the header panel 2.

A filter member 11 is housed within this grill 10.

Reference numeral 12 denotes a cool box made of resin, and this cool box 12 is fixed to the upper surface of the case 1d of the cooling units 1 to 1 with screws through the opening 2a of the header panel 2.

This cool box 12 has a hole in its lower part,
The connecting part 1g of the case 1d of the cooling unit 1 is connected to this hole, and the case 1d and the cool box 12 are connected to each other.
It has a structure that communicates with the.

A thin heat exchanger 13 having a substantially U-shaped appearance is disposed at the bottom of the cool box 12, and this heat exchanger 13 and the heat exchanger 1C of the cooling unit 1 are connected in series. Thus, the refrigerant first flows into the heat exchanger 13 of the cool box 12 and then enters the heat exchanger 1C of the cooling unit 1.

Although not shown, there is another cooling unit on the front side of the vehicle for cooling the driver's seat 3 and passenger seat 4 side.
The heat exchanger of this unit and the heat exchanger 1C of the cooling unit 1 are connected in parallel.

Further, one solenoid valve is connected to each heat exchanger in the refrigeration cycle piping.

A plate-like shelf 14 having a U-shaped appearance is housed in the cool box 12, and is detachably fitted to both ends of the heat exchanger 13.

Note that 15 is an article such as canned juice placed on the shelf 14 in the cool box 12.

16 is a cylindrical decorative board, and this decorative board 16 is fixed to the header plate 2 and the floor panel 17 integrated therewith with screws so as to cover the joint between the cooling unit 1 and the cool box 12. .

Reference numeral 18 denotes a duct for discharging cold air, and this duct 18 is connected to the center pillar 2 between the sliding door 19 for getting on and off the passenger seat 5 and the door 20 for getting on and off the passenger seat 4.
1, that is, in the space between the center pillar 21 and the vehicle body 22.

One end of the duct 18 is connected to the fan casing part 1f of the cooling unit 1, and the other end is connected to a ceiling duct 24 with a cold air outlet 23 mounted on the ceiling of the vehicle interior.

This ceiling duct 24 has a shape that extends in the lateral direction within the vehicle interior, and is fixed to the ceiling with screws.

Further, the duct 18 is connected to the center pillar 2 at one end thereof.
It is fixed with a screw at 1.

Note that the ceiling duct 24 is provided with a cooling switch (not shown), and when this switch is closed, the solenoid valve for the heat exchanger IC of the cooling unit 1 opens, and the cooling box 12 and the heat exchanger of the cooling unit 1 are opened. Refrigerant flows through IC, 13.

In the above configuration, the operation will be explained next.

Due to the rotation of the blower fan 1b, air inside the vehicle enters the case 1d of the cooling unit 1 through the suction grill 10 and the suction port 1e.

The air that has entered the case 1d is cooled by the heat exchanger 1C, becomes cold air, passes through the duct 18, reaches the ceiling duct 24, and is passed through the cold air outlet 23 of the ceiling duct 24 to the passenger seat 5.
It is blown out to the side.

Note that a portion of the cold air reaches the inside of the cool box 12 via the connecting portion 1g of the fan casing portion 1f of the cooling unit 1.

Furthermore, since the heat exchanger 13 is disposed within the cool box 12, the cooling effect of the heat exchanger 13 is added.

Therefore, the inside of the cool box 12 is sufficiently cooled, and the articles 15 placed inside the cool box 12 can be cooled.

To take out the cooled article 15, it is sufficient to open the lid 12a of the cool box 12.

By the way, the cooling unit 1 is housed inside the header panel 2 and is not exposed inside the vehicle, and the cooling unit 1 is not exposed inside the vehicle.
2 Only a will be exposed.

Further, the duct 18 connected to the cooling unit 1 is also housed inside the center pillar 21 and is not exposed inside the vehicle interior.

Therefore, the interior comfort of the vehicle is not impaired, and the noise generated from the cooling unit 1, particularly the blower fan 1b, is less likely to enter the vehicle interior.

Furthermore, even if, for example, the driver's seat 3 is reclined as shown in FIG. 5 (to the position indicated by the two-dot chain line), the cooling unit 1 will not become an obstacle.

In addition, in the said Example, although the cool box 12 was provided in the upper part of the air-conditioning unit 1, it cannot be overemphasized that this cool box 12 does not need to be provided in particular.

The effects of the present invention described above are enumerated as follows.

(1) Since the cooling unit 1 and the duct 18 are not exposed in the vehicle interior, the comfort of the occupants is not impaired, and the safety of the occupants can be improved.

(2) The noise generated from the cooling unit 1 can be shielded, and the discomfort of the occupants can be eliminated.

(3) The driver's seat 3 and/or the passenger seat 4 can be reclined.
