Description

[Detailed Description of the Invention] [Technical Field of the Invention] The invention relates to an air conditioning device for vehicles that is mounted on the ceiling of a vehicle.

[Prior art]

Conventionally, this type of air conditioner has been constructed as shown in FIGS. 1 and 2. That is, in FIG. 1, 1 is the case of the main body of the device;
A compressor 2, an outdoor heat exchanger 3, an outdoor fan 4, an indoor heat exchanger 5, an indoor fan 6, an electrical parts box 7, and the like are installed inside.

FIG. 2 is an enlarged cross-sectional view showing the installed state of the electrical parts box 7, in which 8 is the vehicle ceiling on which the case 1 is placed and has an opening 8a in a part, and 9 is the opening 8a in the case 1. An insertion hole 10 is provided corresponding to the insertion hole 8a, and 10 is a pair of L-shaped receiving fittings or receiving members provided on the inner surface of the case 1, and has a hooking groove 10a in a part thereof. Reference numeral 11 denotes a pair of pins, that is, latching members, which are set on the upper side of the electrical component box 7, and are respectively latched in the latching grooves 10a.

Reference numeral 12 denotes a substantially L-shaped support plate provided near the insertion opening of the case 1, and has a slit 12a in a portion thereof. Reference numeral 13 indicates a support bolt, or mounting rod, which is provided on the bottom surface of the electrical component box 7 and hangs down through the slit 12a, and reference numeral 14 indicates a retaining nut, or stopper, which is screwed onto the support bolt 13 from the outside of the support plate 12. A member 15 is an inspection lid attached to the periphery of the ceiling opening 8a so as to be openable and closable.

In the above configuration, the electrical component box 7
When installing the electrical component box 7, hang the pair of pins 11 provided on the electrical component box 7 onto the metal fittings 10, suspend the electrical component box 7, and then attach the lower support bolt 13.
is inserted into the slit 12a of the support plate 12, and the locking nut 14 is screwed onto the support bolt 13,
An electrical component box 7 is fixed to the main body case 1.

By the way, when inspecting the electric component box 7 while it is placed on the ceiling 8, after opening the inspection lid 15 provided on the vehicle ceiling 8, loosen the locking nut 14 and remove the support bolt 13 from the support plate 12. Disconnect,
Thereafter, with the pin 11 provided on the electrical parts box 7 removed from the bracket 10, it is pulled out into the vehicle through the opening 8a through the insertion port 9 while avoiding the support plate 12, and inspection and repair etc. Ta.

Therefore, in the conventional air conditioner as described above, when inspecting the electrical box, it is necessary to pull it out in a narrow space and be careful not to hit the support plate, making the inspection work difficult. It was extremely difficult.

[Summary of the idea]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional system, and its purpose is to provide a vehicle air conditioner in which the electrical component box can be easily attached and detached by providing a rotatable support plate. It is something to do.

[Example of idea]

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

That is, in FIGS. 3 and 4, 16 is a fixed plate fixed to the inside of the main body case 1, and 17 is a substantially L-shaped support plate having a slit 17a through which the support bolt 13 is inserted. That is, the other part of the support member is pivotally connected to the fixed plate 16 by a shaft 18. In addition, in the figure, the same reference numerals as those shown in FIG. 1 and FIG. 2 indicate the same structure, and the explanation will be omitted.

According to the above configuration, when inspecting the electrical component box 7, the locking nut 14 is first removed from the support bolt 13. The support plate 17 is then rotated about the shaft 18 and dropped to the dotted line position as shown in FIG. As a result, a wide space is formed near the insertion opening 9 of the case, and by removing the pin 11 provided on the electrical component box 7 from the bracket 10, the opening in the ceiling can be opened from the above space. 8a, it can be easily taken out into the vehicle, and inspection and repair can be easily performed.

[Effect of idea]

As described above, since this invention is equipped with a rotatable support plate, it is easy to take out the electrical parts box, inspection and repair are easy, and it has extremely practical effects. be.
