Description

[Detailed Description of the Invention] This invention relates to a vehicle air conditioner that has an improved structure for closing the gap between an indoor heat exchanger and an indoor cover.

A vehicle air conditioner is divided into an outdoor heat exchange section and an indoor heat exchange section.The outdoor heat exchange section is covered by an outdoor cover that has an inlet and an outlet, and the indoor heat exchange section has an inner surface that is insulated. Covered by an indoor force bar with material.

That is, as shown in FIGS. 1 to 3, the main body 3 installed on the roof 2 of the vehicle 1 is provided with outdoor heat exchange parts 4, 4 at both ends in the longitudinal direction, and an indoor heat exchange part 5 is provided in the central part. ing.

The outdoor heat exchange parts 4, 4 include an outdoor heat exchanger 6,
6 and an outdoor blower 7 are provided, which are covered by an outdoor cover 10 having an inlet and an outlet 9, 9.

In addition, the indoor heat exchange section 5 includes an indoor blower 11 in the center.
A pair of indoor heat exchangers on both sides 12. 12 are erected.

A suction port 15 is provided on the bottom plate 13 of the indoor heat exchange section 5 in correspondence with the ceiling plate 14 of the vehicle 1. 15 and an air outlet 16 are provided.

Further, the upper surface of the indoor heat exchange section 5 is closed by an indoor cover 17, and a heat insulating material 18 is adhered to the inner surface of the indoor cover 17 for thermally insulating it from the outdoors.

Further, the pair of indoor heat exchangers 12. Packings 19 , 19 made of foam material or the like are adhered to the upper surface of the interior cover 12 , and this upper surface is joined to the heat insulating material 18 of the indoor cover 17 .

And indoor heat exchanger 12. The gap created between the top surface of the air conditioner 12 and the indoor cover 17 is closed to prevent short-circuiting of return air.

In addition, 20 is a machine room, and compressors 21, 21 are installed inside this machine room.
and an accumulator 22 are installed.

That is, as shown in FIG. 4, the bottom plate 23 of the machine room 20
is provided with a recess 24 for attaching the compressor 21, and the outer circumferential wall of the compressor 21 is fitted with a recess 24 and a hem 24 is provided in the outer peripheral wall of the compressor 21.
A water drop guide cylinder 26 is provided, which extends to the outer periphery of the recess 24.

Then, water droplets etc. generated on the outer surface of the compressor 21 are removed from the recess 24.
The structure is such that the water is drained to the surrounding area by the water drop guide tube 26 without being accumulated in the water.

The vehicle air conditioner constructed in this manner is installed on the roof 2 of the vehicle 1 regardless of the season or off-season, and therefore requires periodic maintenance and inspection.

During such periodic inspections or repairs, a worker may work while climbing on the interior cover 17 of the main body 3 from the roof 2 of the vehicle 1.

At this time, the indoor cover 17 is deformed by the load,
A gap may be formed between the packing 19 and the heat insulating material 18, and the packing 19 may be peeled off from the indoor heat exchanger 12, causing an air short in the return air.

This idea was devised by focusing on the above-mentioned circumstances, and its purpose is to provide a closing member on the top of the indoor heat exchanger that presses against the insulation material of the indoor cover to close the gap, allowing maintenance, inspection, and repair. For vehicles, it can prevent the interior cover from deforming even if a work shell rests on the interior power bar during operation, and it does not cause air shorts even during long-term use, improving durability. The company aims to provide air conditioners.

Hereinafter, this invention will be explained based on one embodiment shown in the drawings.
Since it is the same as the conventional example shown in the figure, the same number is given to FIG. 5 and FIG. 6, and the explanation thereof will be omitted.

That is, a pair of indoor heat exchangers 12, 12 are installed upright on both sides of the indoor blower 11 of the indoor heat exchange section 5.

These indoor heat exchangers12. Mounting hole 31 on the top surface of 12
A mounting plate 32 is fixed thereto.

A closing member 33 bent into an L-shape is joined to the upper surface of the indoor heat exchanger 12, and is tightened and fixed in the mounting hole 31 by a tightening screw 34.

A packing 35 made of rubber or synthetic resin is fitted onto the tip of the upright portion of the closing member 33, and this is covered with the heat insulating material 18 attached to the inner surface of the indoor cover 17.
is pressed against.

Therefore, the gap 36 between the upper surface of the indoor heat exchanger 12, 12 and the inner surface of the indoor cover 17 is blocked by the closing member 33, thereby preventing an air short in the return air.

During cooling operation of the vehicle air conditioner, as the indoor blower 11 rotates, the air inside the vehicle is sucked into the main body 3 through the suction ports 15, 15 as shown by the arrows, and the indoor heat exchanger 12. Pass 12.

At this time, the air sucked into the vehicle is transferred to the indoor heat exchanger 12.
12 exchanges heat with cold air, and this heat exchanged air is blown into the vehicle from an outlet 16 by an indoor blower 11.

At this time, the gap 36 above the indoor heat exchangers 12, 120
is the closing member 33. 33, so there will be no air short circuit.

Moreover, the closing member 33. 33, the indoor cover 17 can be reinforced, and the indoor cover 17 will not be deformed even if a worker steps on the indoor power harness 17 during maintenance, inspection, or repair.

As explained above, in this invention, a closing member is fixed to the top surface of the indoor heat exchanger, and the upper end of this closing member is pressed against the insulation material of the indoor cover, so that the top surface of the indoor heat exchanger and the indoor cover It is possible to completely cut off the gap between the inner surface of the cylinder and the inner surface of the cylinder, preventing short-circuits of return air.

Moreover, the indoor cover can be reinforced by the closing member, and even if a working shell is placed on the indoor cover during maintenance, inspection, or repair, it will not be deformed, and durability can be improved.
