Description

Technical Field

[0001] The present invention relates to the technical field of mounting mechanisms, and in particular to a centrifugal fan mounting mechanism in an air conditioner and a mounting method thereof. Background Art

[0002] The centrifugal fan currently used in air conditioners converts mechanical energy into kinetic energy and pressure energy of gas through a high-speed rotating impeller. It has an impeller, a volute, air inlets and outlets, a motor, bearings and a bracket. When working, the gas enters the center of the impeller from the fan axis. The impeller blades drive the gas to rotate at high speed. The gas is thrown to the outer edge of the impeller under the action of centrifugal force, and the kinetic energy and pressure are significantly increased. The high-speed gas enters the volute-shaped channel, the speed is reduced, and the kinetic energy is further converted into static pressure energy. The high-pressure gas is discharged through the air outlet to complete the transportation or pressurization process.

The rotation of the rotating block 309 drives the bidirectional screw 308 to rotate, and the rotation of the bidirectional screw 308 drives the two movable plates 307 to move toward the middle at the same time, thereby driving the first locking block 309 on the movable plate 307 to rotate. 10 and the second locking block 3011 move toward the middle at the same time, so that the first locking block 3010 passes through the first rectangular hole and is inserted into the first locking groove 305 on the first plug-in block 301, and at the same time, the second locking block 3011 passes through the second rectangular hole and is inserted into the second locking groove 3013 on the second plug-in block 302, thereby realizing rapid locking and limiting of the first plug-in block 301 and the second plug-in block 302, thereby realizing rapid installation and fixation of the centrifugal fan, and further achieving the purpose of facilitating maintenance and replacement of the centrifugal fan body 100.

[0055] On the other hand, an embodiment of the present application further provides a method for installing a centrifugal fan installation mechanism in an air conditioner, comprising the following steps: S1: Installing the mounting base 201: Installing the mounting base 201 at a suitable position in the air conditioner by engaging the mounting bolts with the mounting ears 203; S2: Pre-installation of the centrifugal fan body 100: plugging the centrifugal fan body 100 into the buffer seat 202 through the first plug-in block 301 and the second plug-in block 302; S3: The centrifugal fan body 100 is locked and fixed, and the rotating block 309 is rotated. The rotation of the rotating block 309 drives the bidirectional screw 308 to rotate. The rotation of the bidirectional screw 308 drives the two movable plates 307 to move toward the middle at the same time, and drives the first locking block 3010 to be inserted into the first locking groove 305 on the first plug-in block 301, and at the same time drives the second locking block 3011 to be inserted into the second locking groove 3013 on the second plug-in block 302.

[0056] Working principle: When installing the centrifugal fan body 100, the centrifugal fan body 100 can be inserted into the first plug-in slot 303 and the second plug-in slot 304 on the buffer seat 202 through the first plug-in block 301 and the second plug-in block 302 respectively, and the rotating block 309 is rotated. The rotation of the rotating block 309 drives the bidirectional screw 308 to rotate, and the rotation of the bidirectional screw 308 drives the two moving plates 307 to move toward the middle at the same time, thereby driving the first locking block 3010 and the second locking block 3010 on the moving plate 307 to rotate. 011 are simultaneously moved toward the middle, so that the first locking block 3010 passes through the first rectangular hole and is inserted into the first locking groove 305 on the first plug-in block 301, and at the same time, the second locking block 3011 passes through the second rectangular hole and is inserted into the second locking groove 3013 on the second plug-in block 302, thereby realizing rapid locking and limiting of the first plug-in block 301 and the second plug-in block 302, thereby realizing rapid installation and fixation of the centrifugal fan, and further facilitating maintenance and replacement of the centrifugal fan body 100; During the use of the centrifugal fan body 100 after installation, when the centrifugal fan body 100 vibrates, it can drive the buffer seat 202 to have a tendency to move downward. Under the action of the buffer seat 202 exerting force on the two buffer rods 2010, the two sliding plates 205 tend to move toward the middle respectively. At this time, the force on the buffer seat 202 can be effectively buffered under the interaction of the buffer spring 2011, the tension spring 2012 and the damping shock absorber 2013, thereby achieving effective shock absorption of the centrifugal fan body 100, and thus effectively reducing the noise generated during the operation of the centrifugal fan.
