Detailed Description

In the air conditioner outdoor unit, the outer fan needs to be supported by a motor frame. In the process of mounting the motor frame on the chassis, the motor frame is usually placed at a proper position first, and then a fastener is mounted to fix the motor frame on the chassis. Due to the structural characteristics of the motor frame, the center of gravity of the motor frame is close to the front. When the motor frame is placed at the mounting position and before the fastener is mounted, the motor frame is easy to topple forward, so that an installer is scratched or bruised.

In order to improve the problem that current motor frame emptys forward easily, this application provides a motor frame mounting structure, through setting up the locating part at the motor frame dorsal part and pulling the motor frame, prevents that it from toppling over forward. In addition, this application still provides an outer machine of air conditioner who contains above-mentioned motor frame mounting structure.

FIG. 9 is an enlarged view of detail IX of FIG. 1; fig. 10 is an enlarged view of a portion X in fig. 2. Fig. 9 and 10 show the fitting of the mounting plate 220, the boss 120 and the stopper 300 when the motor mount 200 is placed in the mounting position (without the fastener installed). Referring to fig. 9 and 10 in conjunction with the above figures, after the motor mount 200 is pre-assembled in place, the mounting plate 220 abuts the surface of the boss 120. Specifically, the first plate 221 is attached to the top surfaces of the two bosses 120, and the second plate 223 is attached to the side surface of the same side of the two bosses 120, as shown in fig. 9. The engaging slots 222 of the first plate 221 are engaged with the limiting fasteners 123 on the top surface of the boss 120, and the engaging holes 224 of the second plate 223 are in one-to-one correspondence with the mounting holes 122 on the side surface of the boss 120. Note that the side of the boss 120 abutted by the second plate body 223 is the side of the boss 120 opposite to the insertion groove 121, that is, the side facing the front side.

Meanwhile, the inserting portion 310 of the limiting member 300 is inserted into the inserting groove 121, as shown in fig. 10. Because the inserting part 310 and the connecting part 320 form a certain included angle, and the slot 121 is opened on the side surface of the boss 120, the inserting part 310 of the limiting part 300 can better hook the upper edge of the slot 121, so that the limiting effect is achieved, and the whole motor frame 200 is prevented from toppling forwards.

In the process of placing the motor frame 200 at the installation position, the motor frame 200 may be firstly tilted backward slightly, so that the insertion portion 310 of the limiting member 300 is inserted into the insertion slot 121, and then the motor frame 200 is rotated forward to be erected, so that the clamping slot 222 is matched with the limiting buckle 123 on the boss 120. After the motor mount 200 is placed in the mounting position, the bolts can be installed in the mounting holes 122 and the fitting holes 224.

In an alternative embodiment, the included angle between the connection portion 320 and the insertion portion 310 is 95-105 °, for example, 95 °, 100 °, and 105 °. The angle needs to be set within a reasonable range, and if the angle is too small, the installation of the motor frame 200 is not facilitated; however, the angle is too large, so that the motor frame 200 is easily toppled forward to cause the insertion part 310 to be separated from the slot 121, and the anti-toppling effect is poor.

In the embodiment of the present application, the rack main body 210 is connected to the edge of the mounting plate 220, so that the motor rack 200 is L-shaped, and the distance between the connection position of the mounting plate 220 and the rack main body 210 and the foremost end of the inserting part 310 is greater than 12mm, which is more favorable for improving the installation effect of the motor rack 200.

In the present embodiment, the inserting portion 310 is plate-shaped, the slot 121 is strip-shaped, and in a thickness direction (substantially a height direction in the present embodiment, i.e. a direction indicated by an arrow ef) of the inserting portion 310, a width of the slot 121 is 3 to 6 times of the thickness of the inserting portion 310. It will be appreciated that the width of the slot 121 is too small, which may cause inconvenience in installation, and if the width of the slot 121 is too large, the falling prevention capability of the stopper 300 may be reduced. Therefore, the width of the slot 121 is set to be 3-6 times of the thickness of the insertion part 310, so that the installation efficiency is improved, and the good anti-toppling capability is ensured.

The air conditioner outer unit (not shown in the figure) that this application embodiment provided includes the motor frame mounting structure 010 that this application above-mentioned embodiment provided. The outdoor unit of the air conditioner may further include other necessary components for performing the air conditioning function, such as an external fan, a casing, a compressor, and the like.

In summary, the limiting member 300 is disposed in the motor frame mounting structure 010 of the embodiment of the present application, one end of the limiting member 300 is inserted into the chassis 100, and the other end is connected to the motor frame 200. When an installer installs the motor frame 200 on the chassis 100, the limiting member 300 is located on the back side of the motor frame 200 relative to the installer, so that the limiting member 300 can pull the motor frame 200 on the back side of the motor frame 200, so that the motor frame 200 cannot topple forward, and the installer is protected from being scratched or bruised due to toppling of the motor frame 200.
