Description

[Detailed Description of the Invention] The present invention relates to a fan mounting structure, and provides a fan mounting structure with reliable alignment and good workability.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7.

1 is an integrated air conditioner main body, with a base 2 on the bottom, a top plate 3 on the top, a cabinet 4 on the side,
A front panel 7 having an indoor air inlet 5 and a vertically elongated outlet 6 is arranged at the upper front surface, and an outdoor air inlet 8 and an outdoor outlet 9 for outdoor air are similarly arranged at the rear. It is what it is. A cooler 10 is installed immediately after the suction port 5, and a condenser 11 is installed immediately after the outdoor suction port 8. Reference numeral 12 denotes a casing that is the core inside the integrated air conditioner main body 1, and the cross-sectional shape of the indoor air blowing chamber 13 that forms a blowing path for indoor air and the outdoor blowing chamber 14 that forms a blowing path for outdoor air are shown. They are formed back to back to form an S-shape, and an upper partition wall 15 is formed on the upper surface to serve as the upper partition of each ventilation chamber, and the upper partition wall 15 has a fan 23 for attaching and detaching on the side of each ventilation chamber. A through hole 16 is provided at the lower end of the indoor air blowing chamber 13, and a motor mounting portion 18 is provided at the lower end of the indoor ventilation chamber 13 to serve as a partition from a component chamber 17 that stores a compressor 28, electrical components, etc. (not shown) installed below. It is a plastic molded product that is integrally formed with the inner partition wall 19. Outdoor ventilation chamber 1
4 is formed over the entire height of the casing 12, so the base 2 also serves as a lower partition.
Reference numeral 20 denotes a heat insulating plate necessary to prevent dew from forming on the top plate 3 during cooling operation, and is a molded product of polystyrene foam. A bearing portion 21 that accommodates a bearing 26 for aligning the fan 23 is provided on the upper surface of the heat insulating plate 20.
A convex portion 22 having the same pitch as the two through holes 16 and minimizing the gap with the through holes 16 is provided on the lower surface.

23 is a long cylindrical fan with a bearing 26 on the top surface.
An alignment rod 24 is provided which rotatably engages with the motor 27, and a boss 25 which is pivotally fixed to the motor 27 is provided on the lower surface. The fan 23 blows air by receiving the rotational power of the motor 27, and indoor air is cooled from the suction port 5 through the cooler 10, guided into the indoor ventilation chamber 13, and blown out from the blowout port 6. Similarly, outdoor air passes through the condenser 11 from the outdoor suction port 8, promotes condensation in the condenser 11, is guided into the outdoor air blowing chamber 14, and is blown out from the outdoor air outlet 9.

Next, a method of attaching the fan 23 will be explained. After installing the casing 12 on the base 2, the motor 27 is inserted into the motor mounting portion 18, and the motor 27 is fixed by attaching a motor holder 29 from the front. Next, insert the fan 23 through the through hole 16,
Set screw 30 between the shaft of motor 27 and boss 25.
Fix it by.

Next, the heat insulating board 20 is placed on the upper partition wall 15 at the convex portion 22.
After the bearing 26 is installed so as to be inserted into the through hole 16, the bearing 26 is housed in the bearing portion 21. At this time, the alignment rod 24 is inserted into the bearing 26, and the installation of the fan 23 is completed. However, if this continues, the insulation board 2
0 and the bearing 26 would move upwards, so the top plate 3 is attached to prevent it from moving upward.

According to the above, since the casing 12 is an integrally molded product, the alignment accuracy of the fan 23 is improved, and since the bearing 26 is simply housed in the bearing portion 21 of the heat insulating plate 20, the installation of the bearing 26 is minimized. This is a fan mounting structure that requires only a few parts and has excellent workability.

As described above, according to the present invention, it is possible to provide a highly reliable product with reliable alignment of the fan and no need to worry about the fan hitting each other, and in addition, it is possible to provide an inexpensive product with a small number of parts and good workability. be.
