Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner. Background Art

[0002] The air conditioner's outdoor unit consists of a housing, housing a heat exchanger, fan, motor, and motor bracket. The motor bracket's lower end is connected to the bottom of the housing, while its upper end is connected to the top. The motor is mounted on the motor bracket, driving the fan. When the outdoor unit is operating, the fan rotates, drawing air in from the heat exchanger. After exchanging heat with the refrigerant in the heat exchanger, the air flows through the motor bracket, is boosted by the fan, and then released to the outside through the air guide ring and outlet grille.

[0003] The motor bracket is secured to the housing and the motor with screws, lacking a retaining mechanism, resulting in inefficient installation. Furthermore, since the motor bracket bears the weight of the motor and fan, it requires a design that increases its structural strength. However, the structural strength design of the motor bracket overlooked the issue of fluid noise caused by the structural shape obstructing incoming flow.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0065] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0066] In some embodiments, an air conditioner is provided that performs a refrigeration cycle using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0067] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0068] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0069] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0070] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0071] In some embodiments, reference Figure 1 and Figure 2 The outdoor unit includes a housing 100, which forms the outer contour of the outdoor unit. For example, the housing 100 is a rectangular structure. An installation cavity is formed inside the housing 100.

[0072] An air outlet 111 is provided on the front panel 110 of the housing 100 , and an air return port is provided on the back panel of the housing 100 .

[0073] The outdoor unit includes a heat exchanger 200. The heat exchanger 200 is fixedly arranged in the installation cavity and is configured to exchange heat with the air flowing through it.

[0074] For example, refer to Figure 2 and Figure 4 The heat exchanger 200 is an L-shaped heat exchanger, comprising a first heat exchanger section 210 and a second heat exchanger section 220. The first heat exchanger section 210 is longer than the second heat exchanger section 220, forming an L-shaped structure. The first heat exchanger section 210 is positioned near the rear panel of the housing 100, while the second heat exchanger section 220 is positioned near a side of the housing 100, such as the left panel.

[0075] The outdoor unit includes a fan, which includes a motor 300 and fan blades. The motor 300 is configured to drive the fan blades to rotate. The fan is configured to provide power for air circulation.

[0076] The fan is started, and under the action of the fan, the outside air flows into the inner cavity of the shell 100 through the return air port, flows through the heat exchanger 200, and is discharged from the air outlet 111 after heat exchange.

[0077] The outdoor unit includes a motor bracket 400, referring to Figures 6 to 9 The motor bracket 400 includes a vertical portion 410. The motor bracket 400 includes a first transverse portion 420. The motor bracket 400 includes a second transverse portion 430. The first transverse portion 420 is provided at the top of the vertical portion 410, and the second transverse portion 430 is provided at the bottom of the vertical portion 410. The first transverse portion 420 and the second transverse portion 430 extend toward the same side of the vertical portion 410, for example, toward the front side of the housing 100.

[0078] The vertical portion 410 is provided with a motor 300, referring to Figure 4 The first transverse portion 420 and the second transverse portion 430 are connected to the housing 100 to achieve fixed installation of the motor bracket 400 in the housing 100. For example, the first transverse portion 420 is fixedly connected to the front panel 110 of the housing 100, and the second transverse portion 430 is fixedly connected to the bottom plate 120 of the housing 100.

[0079] The outdoor unit includes a positioning structure configured to pre-position the installation between the housing 100 and the first and second transverse portions 420 and 430 .

[0080] The motor bracket 400 can be pre-positioned for installation by using the positioning structure, which helps to reduce assembly time and improve installation efficiency.

[0081] In some embodiments, the positioning structure includes a first positioning structure 610 disposed between the first transverse portion 420 and the front panel 110 of the housing 100 , and serves to pre-position the first transverse portion 420 and the front panel 110 .

[0082] The positioning structure includes a second positioning structure 620 , which is disposed between the second transverse portion 430 and the bottom plate 120 of the housing 100 and plays a pre-positioning role in the installation between the second transverse portion 430 and the bottom plate 120 .

[0083] The positioning structure includes a third positioning structure 630 , which is disposed between the motor 300 and the vertical portion 410 and plays a role in pre-positioning the installation of the motor 300 .

[0084] By setting up multiple positioning structures, the installation between the motor bracket 400 and the shell 100, and the motor bracket 400 and the motor 300 is pre-positioned, thereby improving assembly efficiency without additionally increasing the resistance of the motor bracket 400 to the air supply airflow.

[0085] In some embodiments, a plurality of first vents 411 are provided on the vertical portion 410 , and the plurality of first vents 411 are spaced apart along the height direction of the vertical portion 410 . A second vent 421 is provided on the first transverse portion 420 .

[0086] The motor bracket 400 is located between the heat exchanger 200 and the air outlet 111 . When the gas flows toward the air outlet 111 , it flows through the motor bracket 400 , thereby generating flow noise.

[0087] To reduce the noise from the motor bracket 400, one existing solution is to create a hollow cavity structure with sound-absorbing holes. However, this is difficult to manufacture and increases mold costs. Another existing solution is to replace the vertical motor bracket 400 with an arched one, where the motor 300 is mounted protrudes toward the fan, with the upper and lower ends of the motor bracket 400 curved toward the heat exchanger 200. This solution is not conducive to controlling the overall width of the machine.

[0088] The motor bracket 400 of this embodiment reduces the resistance of the motor bracket 400 to the air supply airflow by providing the first vent 411 and the second vent 421 , thereby reducing noise, and also helps to reduce sheet metal consumables of the motor bracket 400 and reduce material costs.

[0089] If only the first vent 411 is provided on the vertical portion 410, and the second vent 421 is not provided on the first transverse portion 420, the airflow resistance of the first transverse portion 420 will increase. At the same time, the low-speed eddies after passing through the vertical portion 410 will converge to form a large low-speed zone, resulting in large pressure fluctuations on the windward and leeward sides of the first transverse portion 420, affecting the overall noise level. Therefore, providing a connection between the first vent 411 and the second vent 421 at the top solves this problem and further reduces noise.

[0090] In some embodiments, reference Figure 9 The width of the first transverse portion 420 is W1, the width of the second vent 421 is W2, and W2 / W1=0.65-0.75. For example, W2 / W1=0.71.

[0091] If the width of the second vent 421 is too large, the motor bracket 400 will be insufficiently strong and easily break. If the width of the second vent 421 is too small, the air flow resistance will increase.

[0092] In some embodiments, reference Figure 9 The length of the first transverse portion 420 is L1, the length of the second vent 421 is L2, and L2 / L1=0.2-0.3. For example, L2 / L1=0.25.

[0093] If the length of the second vent 421 is too large, the motor bracket 400 will be insufficiently strong and prone to breakage. If the length of the second vent 421 is too small, the air flow resistance will increase.

[0094] In some embodiments, reference Figure 6 Five first vents 411 are provided on the vertical portion 410, with a crossbeam between two adjacent first vents 411. The five first vents 411 are labeled first vent 411A, first vent 411B, first vent 411C, first vent 411D, and first vent 411E. First vent 411A, first vent 411B, first vent 411C, first vent 411D, and first vent 411E are arranged from top to bottom along the height direction of the vertical portion. First vent 411A is connected to second vent 421.

[0095] In some embodiments, reference Figure 6 and Figure 7 The first transverse portion 420 is provided with a flange 424 on a side close to the front panel 110 of the housing 100. The flange 424 extends downward from the first transverse portion 420 and is provided with a first protrusion 425 and a first mounting hole 426. For example, the flange 424 may be provided with two first protrusions 425 and two first mounting holes 426, and the two first mounting holes 426 are provided on the outside of the two first protrusions 425.

[0096] The first protrusion 425 is a bent structure that is bent from the flange 424 toward the front side plate of the housing 100 , which is easy to process and manufacture.

[0097] Reference Figure 3 The front panel 110 of the housing 100 is provided with a first positioning hole 112 and a second mounting hole 113. For example, two first positioning holes 112 and two second mounting holes 113 are provided on the front panel 110 of the housing 100.

[0098] The first protrusion 425 is inserted into the first positioning hole 112 , and a connecting member (such as a screw) is passed through the first mounting hole 426 and the second mounting hole 113 to achieve a fixed connection between the first transverse portion 420 and the front panel 110 of the housing 100 .

[0099] The cooperation between the first protrusion 425 and the first positioning hole 112 plays a pre-positioning role in the installation of the first transverse portion 420, so that the first mounting hole 426 and the second mounting hole 113 can be aligned, which facilitates the subsequent screw driving operation and improves assembly efficiency.

[0100] In some embodiments, reference Figure 6 and Figure 8 The second transverse portion 430 is provided with a second positioning hole 431 and a third mounting hole 432. For example, two second positioning holes 431 and three mounting holes 432 are provided on the second transverse portion 430. The second positioning hole 431 is close to one side of the vertical portion 410, and the third mounting hole 432 is close to the front end of the second transverse portion 430.

[0101] Reference Figure 5 The bottom plate 120 of the housing 100 is provided with a second protrusion 121 and a fourth mounting hole 122. For example, the bottom plate 120 is provided with two second protrusions 121 and two fourth mounting holes 122.

[0102] The second protrusion 121 is a bent structure bent upward from the bottom plate 120 , which is easy to process and manufacture.

[0103] The second protrusion 121 is inserted into the second positioning hole 431 , and a connecting member (such as a screw) passes through the third mounting hole 432 and the fourth mounting hole 122 .

[0104] The cooperation between the second protrusion 121 and the second positioning hole 431 plays a pre-positioning role in the installation of the second transverse portion 430, so that the third mounting hole 432 and the fourth mounting hole 122 can be aligned, which facilitates the subsequent screwing operation and improves assembly efficiency.

[0105] In some embodiments, reference Figure 4The outdoor unit further includes a mounting portion 500 , the vertical portion 410 is provided with the mounting portion 500 , and the motor 300 is provided on the mounting portion 500 .

[0106] The mounting portion 500 is a sheet metal component and includes a mounting portion section 510. The mounting portion section 510 extends along the height direction of the vertical portion.

[0107] The mounting portion 500 includes a second mounting portion section 520 . The second mounting portion section 520 is provided on the upper side and the lower side of the first mounting portion 510 . The second mounting portion section 520 extends obliquely from the first mounting portion section 510 toward the vertical portion 410 .

[0108] The mounting portion 500 includes a third mounting portion section 530 . The third mounting portion section 530 is disposed on the upper side of any second mounting portion section 520 , and the third mounting portion section 530 extends along the height direction of the vertical portion 410 .

[0109] The third section 530 of the mounting portion is connected to the vertical portion 410 , thereby achieving a fixed connection between the mounting portion 500 and the vertical portion 410 .

[0110] The first section 510 of the mounting portion is connected to the motor 300 to achieve a fixed connection of the fan on the vertical portion 410 .

[0111] The mounting portion 500 faces one of the plurality of first vents 411. For example, the mounting portion 500 faces the first vent 411C. A gap exists between the vertical portion 410 and the first mounting portion section 510. The mounting portion 500 does not block the first vent 411C. After passing through the first vent 411C, air flows out through the gap between the vertical portion 410 and the first mounting portion section 510.

[0112] In some embodiments, reference Figure 10 The mounting portion 500 is provided with a third positioning hole 531 and a fifth mounting hole 532 . For example, the third section 530 of the mounting portion is provided with a third positioning hole 531 and a fifth mounting hole 532 .

[0113] Reference Figure 4 A third protrusion 414 and a sixth mounting hole 415 are provided on the vertical portion 410. The third protrusion 414 is inserted into the third positioning hole 531. The connecting part (such as a screw) is passed through the fifth mounting hole 532 and the sixth mounting hole 415 to realize the fixed installation of the mounting portion 500 on the vertical portion 410.

[0114] The third protrusion 414 is a positioning column structure, which is easy to process and manufacture. The third protrusion 414 cooperates with the third positioning hole 531 to pre-position the installation of the mounting portion 500, thereby improving assembly efficiency.
