Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioner technology, and in particular to an outdoor unit motor bracket and an outdoor unit of an air conditioner. Background Technology
[0002] Split-type air conditioning units generally consist of an indoor unit and an outdoor unit. The compressor, condenser, and fan together form one unit, located outdoors, called the outdoor unit. The evaporator, blower, air filter, heater, humidifier, etc., form another unit, located indoors, called the indoor unit. Typically, the outdoor unit contains a fan to dissipate heat from the condenser, improving its heat exchange efficiency. The fan motor is mounted inside the outdoor unit casing via a motor bracket, which is usually a sheet metal part. Traditional air conditioner outdoor unit motor brackets are prone to resonance during vibration testing, causing structural damage. During user operation, this results in noticeable vibration and noise, negatively impacting the user experience.

[0057] Figure 1 This is a schematic structural diagram of an air conditioner outdoor unit motor bracket according to an embodiment of the present invention; as shown Figure 1 As shown, and refer to Figure 2 and Figure 3 This invention provides an outdoor unit motor bracket for an air conditioner, including a bracket body 20 for mounting the motor, and further including two first flanges 21 and two second flanges 22. Each first flange 21 extends rearward from a side edge of the bracket body 20 extending in a vertical direction. Each second flange 22 is disposed below a first flange 21, and each second flange 22 extends forward from a side edge of the bracket body 20 extending in a vertical direction. The second flanges 22 are located at the bottom of the bracket body 20.
[0058] The air conditioner outdoor unit motor bracket provided in this embodiment of the invention, due to the specially designed first flange 21 and second flange 22, eliminates the need for a thick bracket body 20 and avoids the resonant frequency range, thus reducing noise. Specifically, without changing the bracket thickness, the sheet metal wall thickness can be 0.6mm to 1mm, preferably 0.8mm, saving material costs and increasing the lowest-order modal frequency of the motor bracket to 59Hz. Since the typical motor frequency is 40-50Hz, this avoids the resonant frequency range and reduces noise.
[0059] In some preferred embodiments of the present invention, the first flange 21 and the corresponding second flange 22 are spaced apart, and the side edge of the corresponding support body 20 has an arc-shaped notch 23. The defining surface of the arc-shaped notch 23 connects the lower end surface of the first flange 21 and the upper end surface of the second flange 22. By setting the arc-shaped notch 23, the resonant frequency range can also be avoided, and noise can be reduced.
[0060] Specifically, the bracket body 20, the first flange 21, and the second flange 22 are formed by bending and / or stamping a sheet metal. A notch is first formed between the first flange 21 and the second flange 22 before the first flange 21 and the second flange 22 are formed. The notch is defined by the lower end face of the first flange 21, the upper end face of the second flange 22, and a bottom limiting surface, with the bottom limiting surface being arc-shaped. This results in an arc-shaped notch 23 between the first flange 21 and the corresponding second flange 22. Formed by bending and / or stamping a sheet metal, the design and manufacturing are convenient, and the first flange 21, the second flange 22, and the notch are all easily formed, resulting in low cost.
[0061] In some embodiments of the invention, such as Figures 4 to 7 As shown, and with reference Figures 1 to 3 The bracket body 20 is provided with a motor mounting hole 24 and at least one lower ventilation hole located below the motor mounting hole 24. The lower end of the first flange 21 is located below the lower ventilation hole.

Each second lower ventilation hole 26 extends vertically, and the two second lower ventilation holes 26 are arranged alternately along the width direction of the support body 20, with the two second lower ventilation holes 26 located below the first lower ventilation hole 25. All or part of the portion between the two second lower ventilation holes 26 of the support body 20 is a reinforcing connection section 28. The reinforcing connection section 28 between the two second lower ventilation holes 26 can enhance torsional stiffness.
[0063] The support body 20 is also provided with at least one upper ventilation hole 27 located above the motor mounting hole 24. Each upper ventilation hole 27 is a rectangular hole, and each lower ventilation hole is a rectangular hole. An upper ventilation hole flange extends rearward from the edge of each upper ventilation hole 27. A lower ventilation hole flange extends rearward from the edge of each lower ventilation hole. The upper ventilation holes 27 and the lower ventilation holes facilitate airflow and improve heat exchange efficiency.
[0064] A flange extending rearward from the edge of the motor mounting hole 24 extends from the motor mounting hole 24. The bracket body 20 also has forward-protruding motor mounting bosses 29 located around the motor mounting hole 24. This design ensures a secure motor mounting.
[0065] In some embodiments of the present invention, the bracket body 20 further includes two upper end face reinforcing ribs 31 extending in the vertical direction and two lower end face reinforcing ribs 32 extending in the vertical direction. The two upper end face reinforcing ribs 31 are located on both sides of the upper ventilation hole 27, with their lower ends located on both sides of the upper part of the motor mounting hole 24, and their upper ends located on the upper side of the upper ventilation hole 27 or flush with its upper edge. The two lower end face reinforcing ribs 32 are located on both sides of the lower ventilation hole, with their upper ends located on both sides of the lower part of the motor mounting hole 24, and their lower ends located on the lower side of the lower ventilation hole, between the two second flanges 22. The length of the lower end face reinforcing ribs 32 must exceed the arc-shaped notch 23 to strengthen the rigidity at the arc-shaped notch 23 and avoid the resonant frequency range, etc.
[0066] Two upper end face reinforcing ribs 31 are respectively located directly above two lower end face reinforcing ribs 32. Each upper end face reinforcing rib 31 protrudes rearward and is formed by stamping rearward on the plate forming the support body 20. Each lower end face reinforcing rib 32 protrudes rearward and is formed by stamping rearward on the plate forming the support body 20.
