Description

Technical Field

[0001] This utility model relates to the field of refrigerator fan motor assembly technology, and more specifically to a refrigerator fan motor assembly. Background Technology

[0002] The refrigerator fan motor assembly is primarily used to circulate air within the refrigerator, ensuring even distribution of cold air and improving cooling efficiency and temperature uniformity. Through forced convection, it accelerates heat exchange between the evaporator and condenser, assisting the refrigerator in achieving rapid cooling and maintaining a constant temperature in all corners, thus promoting food preservation. Simultaneously, this assembly also undertakes some heat dissipation tasks, ensuring the normal operation of the refrigerator components.

[0003] When the refrigerator and its appliances are working together, dust can easily enter around the motor and accumulate on its surface and inside. The motor generates heat during operation, and dust accumulation affects its heat dissipation, causing the motor temperature to rise. This reduces the motor's efficiency and lifespan. Furthermore, conventional fan motor units occupy a large area, are difficult to install and disassemble, and also impact future maintenance.

[0004] Therefore, in order to solve the above problems, this application provides a refrigerator fan motor assembly. Utility Model Content

[0007] Preferably, the dustproof component includes a rear plate, a first fixing rivet, and a dustproof shell. The first fixing rivet is distributed in a ring and is fixedly connected to the outer wall of the rear plate and the inner wall of the dustproof shell. The dustproof component helps the device to effectively protect the drive component from dust ingress during operation, thereby reducing the impact on the device's power.

[0008] Preferably, the wall-mounting assembly includes a front mounting plate, a rear mounting plate, a first slot, a pin, and a hook. The rear mounting plate is movably engaged with the rear wall of the front mounting plate. The front and rear mounting plates each have a matrix-distributed first slot on their upper surfaces. The pin is movably engaged with the first slots on the upper surfaces of the front and rear mounting plates. The hook is fixedly installed on the rear wall of the rear mounting plate. This wall-mounting assembly facilitates easy installation and disassembly of the device.

[0019] Reference Figure 1-3 This utility model provides a refrigerator fan motor assembly, including a wall-mounted component 1, a dustproof component 2, a drive component 3, and a housing component 4. The wall-mounted component 1 is symmetrically distributed and installed on the rear wall of the dustproof component 2, the drive component 3 is installed inside the dustproof component 2, and the housing component 4 is installed on the outer wall of the dustproof component 2.

[0020] The wall-mounting assembly 1 includes a front mounting plate 101, a rear mounting plate 102, a first slot 103, a pin 104, and a hook 105. The rear mounting plate 102 is movably engaged with the rear wall of the front mounting plate 101. The front mounting plate 101 and the rear mounting plate 102 are each provided with a matrix of first slots 103. The pin 104 is movably engaged with the first slots 103 provided with the front mounting plate 101 and the rear mounting plate 102. The hook 105 is fixedly installed on the rear wall of the rear mounting plate 102. The wall-mounting assembly 1 facilitates easy installation and disassembly of the device.

[0021] The dustproof component 2 includes a rear plate 201, a first fixing rivet 202, and a dustproof shell 203. The first fixing rivet 202 is distributed in a ring and is fixedly connected to the outer wall of the rear plate 201 and the inner wall of the dustproof shell 203. The dustproof component 2 helps the device to effectively protect the drive component 3 from dust ingress during operation, thereby reducing the impact on the device's power.

[0022] The drive assembly 3 includes a drive motor 301, a sleeve 302, and fan blades 303. The drive motor 301 is fixedly installed on the front wall of the rear plate 201. The output end of the drive motor 301 extends through the top of the dustproof shell 203. The sleeve 302 is fixedly connected to the output end of the drive motor 301. The fan blades 303 are distributed in a ring and fixedly installed on the outer wall of the sleeve 302.

[0023] The housing assembly 4 includes a bottom shell 401, an air intake 402, a second fixing rivet 403, a front shell 404, an exhaust vent 405, and an outer shell 406. The bottom shell 401 is fixedly installed above the dustproof shell 203. The bottom shell 401 has annularly distributed air intake vents 402. The second fixing rivets 403 are annularly distributed and movably pass through the bottom of the bottom shell 401 to fix it to the bottom of the outer shell 406.

[0024] The working principle of this utility model:

[0025] After adjusting the rear mounting plate 102 to a suitable height, the pin 104 is installed into the first slot 103 above the front mounting plate 101 and the rear mounting plate 102 to determine the device's position. At this point, the operator simply needs to hang the hook 105 on the device behind the refrigerator to continue operation. When the device starts working, the output of the drive motor 301 drives the sleeve 302 to rotate. The rotation of the sleeve 302 drives the annularly distributed fan blades 303 to rotate, thereby achieving the function of heat dissipation or air circulation for the refrigerator. During operation, the dust cover 203 effectively protects the refrigerator from dust. To prevent dust from entering the dustproof housing 203 after prolonged operation, thus affecting the service life of the drive motor 301, and to prevent excessive dust accumulation on the fan blades 303 due to prolonged operation, which can affect the working efficiency of the device to some extent, the operator only needs to remove the second fixing rivet 403 and remove the outer casing 406 from the top of the bottom casing 401 to clean the fan blades 303. If the drive motor 301 needs maintenance, the operator only needs to remove the first fixing rivet 202 from the top of the rear plate 201 to perform maintenance on the drive motor 301.
