Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an air conditioner for a vehicle, and particularly to an air conditioner in which the mounting position of a control box is devised.

(Prior Art) The control box of an air conditioner incorporates a plurality of relays to control the clutch, blower, engine, etc. This control relay uses a current of about 30 A, and it is known that the control box itself is extremely large.

The above control box is for sub-engine, compressor,
It is a constituent unit of air conditioning equipment along with blowers, etc.
It is desirable to arrange it near other constituent units such as the above-mentioned sub-engine. However, if the control box is disposed close to the mounting position of the sub-engine, it will receive the vibrations of the sub-engine via the sub-engine mounting cooler mat. Electrical equipment is generally sensitive to vibrations and heat, and control boxes are also susceptible to failure due to the heat radiated from the sub-engine.

Conventionally, the control box 30 was separated from the other constituent units 31 of the air conditioner and placed in the baggage room 32 under the floor of the vehicle, as shown in FIGS. 6 and 7.

(Problems to be Solved by the Invention) For this reason, conventional vehicle air conditioners have the disadvantage of narrowing the effective space of the baggage room 32 and requiring a large number of wires 33 to be extended long into the baggage room. Ta.

(Means for Solving the Problems) The present invention has been made for the purpose of providing a vehicle air conditioner that solves the above-mentioned drawbacks, and for this purpose, the following technical means are employed.

That is, the present invention provides an air conditioner in which the base of the air duct has a curved rising part under the vehicle floor, and the control box, which is one of the constituent units of the air conditioner, is separated from the other constituent units and installed in the air conditioner. It is placed in the space below the rising part of
Another object of the present invention is to provide a vehicle air conditioner in which an opening/closing door is attached to a vehicle frame facing the control surface of the control box.

(Function) According to the above configuration, since the control box is arranged at the base of the duct which is located near other constituent units, it is possible to avoid narrowing the effective space of the baggage room, and it is also possible to avoid wiring to the control box. The route becomes extremely short. Since the control box is separated from other constituent units such as the sub-engine, the control box is not subject to vibrations or radiant heat from the sub-engine, as in the past, and as a result, the control box Does not increase the cause of failure.

(Example) The present invention will be explained below based on the drawings of FIGS. 1 to 5.

Figure 1 is a plan view showing one embodiment of the present invention;
The figure is a front view of the same as above, FIG. 3 is an enlarged view of the main part, FIG. 4 is a view taken along the line A-A in FIG. 3, and FIG. 5 is a view taken along the line B-B in FIG. 4.

The vehicle to which the air conditioner 1 according to the present invention is installed has a shape in which the blower duct 3 having the base 2 under the floor has a curved rising part 4, in other words, a shape having a space 5 under the rising part 4. The base 2 of the air duct 3 extends to the rear side (right side in FIG. 3), and the air blower 7 is housed in the extended portion 6.

A rotating shaft 8 of the blower 7 extends in the width direction of the vehicle 9, and a power shaft 11 of the sub-engine 10.
It is connected to the. In the middle of the power shaft 11,
A pulley 12 is fitted and fixed on the outside, and a belt 13 wound around the pulley 12 drives a pair of compressors 14 disposed at the front and rear of the pulley 12, and the power shaft 11 is connected to a sub-engine. A fan 15 is attached to the protruding end of the condenser 10, and a condenser and a radiator 16 are disposed facing the fan 15. Reference numeral 17 denotes a cooling device disposed on the other side of the extension portion 6 .

Of the above-mentioned air conditioner, the constituent units other than the control box 18, that is, the sub-engine 10, etc., are all disposed immediately after the base 2 of the ventilation duct 3, and are mounted on a support frame 19 fixed under the floor of the vehicle 9. Fixed support. Reference numeral 20 denotes a baggage room, which is sectioned immediately behind the support frame 19 on the rear side.

The remaining units that make up the air conditioner 1,
That is, the control box 18 controls the sub-engine 10.
In order to avoid vibration and radiant heat, the above-mentioned ventilation duct 3
It is disposed in a space 5 below the rising portion 4 of.

Specifically, a bracket 21 is fixed to the front surface of the cooling device 17 so as to protrude into the space 5, and
The control box 18 is fixedly supported on this bracket 21. Also, the control surface 2 of the control box 18
An opening/closing door 24 that slides or rotates to open and close is attached to the vehicle frame 23 facing the vehicle frame 2, so as not to interfere with the adjustment operation of the control box 18.

(Effects of the Invention) As explained above, the present invention is an air conditioner in which the base of the air duct has a curved rising part under the vehicle floor, and the control box, which is one of the constituent units of the air conditioner, The control box is separated from other constituent units and arranged in a space below the rising part of the air duct, and is configured with an opening/closing door attached to the vehicle frame facing the control surface of the control box. Since it operates without being subjected to sub-engine vibration or radiant heat, there are few causes of failure.Furthermore, since it is installed in the space under the rising part of the ventilation duct, it can take up a large amount of effective space in the baggage room. The present invention has various practical advantages, such as requiring only a short wiring route and having an opening/closing door so that there is no problem in adjusting the control box.
