Description

[Detailed Description of the Invention] This invention mainly relates to an improvement in the mounting structure of a motor used for blowing air in an air conditioner.

The mounting structure of a motor in a conventional air conditioner is constructed as shown in FIG. That is, the first
In the figure, 1 is a motor, 2 is a u having a semicircular hole in the upper edge of the upright surface and notch claws 21 at both ends.
The letter-shaped motor support plate 3 is attached to the boss portion 11 of the motor 1.
4 is a reinforcing ring fitted to the outer periphery of the vibration isolating rubber 3; 5 is a ring-shaped vibration-proof rubber attached to the motor support plate 2 in order to fix the motor 1 to the motor support plate 2; This is a motor fixing plate provided with a slit 51 to be hung and a hole for a tightening bolt 6 at the other end.

The motor mounting structure constructed in this manner has a complicated structure and a large number of parts, and the screwing direction of the motor fixing plate is horizontal, resulting in poor workability and increased costs.

This invention was made with attention to this point, and attempts to eliminate the drawbacks of the conventional motor by changing the shapes of the motor support plate and the vibration isolating rubber.

An embodiment of this invention will be described below based on the drawings. In FIGS. 2 to 5, reference numeral 2 denotes a U-shaped motor support plate, and the upper edge of the upright surface is bent approximately at right angles to the upright surface, and the bent portion 2 has a screw hole.
2, and a U-shaped notch 23 is provided in the center. 3 is an insertion hole 31 inserted into the boss portion 11 of the motor 1 and a cutout portion 2 of the motor support plate 2.
A fitting part 32 that is fitted into the motor support plate 2 and a mounting part 33 that is mounted on the bent part 22 of the motor support plate 2 are integrally formed with vibration-proof rubber, and the mounting part 33 has a hole for mounting. It is provided. Reference numeral 7 denotes a U-shaped fixing plate having a bent piece 71 smaller in size than the thickness of the mounting portion 33 of the vibration isolating rubber 3.

To assemble the product configured in this way, first insert the boss portion 11 of the motor 1 into the insertion hole 31 of the vibration isolating rubber 3.
Then, the fitting part 32 of the vibration isolating rubber 3 is fitted into the notch 23 of the motor support plate 2, and the mounting part 33 of the vibration isolator 3 is placed on the bent part 22 of the motor support plate 2. If the fixing plate 7 is placed on the mounting part 33 and screwed to the motor support plate 2, the bent piece 71 of the fixing plate 7
The amount of compression of the vibration isolating rubber is regulated to a predetermined amount, and the motor 1 is fixed to the motor support plate 2.

As mentioned above, in this invention, after attaching the vibration-proof rubber to the boss of the motor, it is inserted into a notch deeper than the diameter of the boss, and then screwed through the U-shaped fixing plate. No rattling of the motor or local distortion of the anti-vibration rubber when installed.
Therefore, the motor can be reliably supported and vibration-proofed, and the structure can be simplified, and there is no need to support each component during screw tightening work, which has the advantage of improving workability.
