For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The air conditioner outdoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, an air-conditioning outdoor unit 100 according to an embodiment of the present utility model includes a chassis 1 and a shell 2 .

[0040] Specifically, Figure 1As shown, the housing 2 is disposed above the chassis 1 and connected to the chassis 1. The housing 2 and the chassis 1 define an installation cavity, and the installation cavity includes a fan cavity 21 and a compressor cavity 22 that are spaced apart. The fan cavity 21 and the compressor cavity 22 may be spaced apart along the length direction of the chassis 1, and a middle partition may be provided in the installation cavity, and the middle partition is used to separate the installation cavity into the fan cavity 21 and the compressor cavity 22.

[0041] like Figure 1 As shown, the air conditioner outdoor unit 100 may also include a fan assembly, a heat exchanger 3 and a compressor 6. The heat exchanger 3 and the fan assembly are arranged in the fan cavity 21, and the compressor 6 is arranged in the compressor cavity 22. The fan assembly includes a wind wheel 5 and a motor for driving the wind wheel 5 to rotate. A motor bracket 7 may also be arranged in the fan cavity 21, and the motor bracket 7 is used to support the motor. The housing 2 is also provided with an air inlet and an air outlet connected to the fan cavity 21. Under the action of the wind wheel 5, the airflow enters the fan cavity 21 from the air inlet, and exchanges heat with the heat exchanger 3 in the fan cavity 21. The airflow after heat exchange is discharged through the air outlet.

[0042] like Figure 3-Figure 5 As shown, the chassis 1 has a defrost air duct 11 and an air intake hole 131 and an air exhaust hole 132 connected to the defrost air duct 11. The air intake hole 131 is connected to the compressor chamber 22, and the air exhaust hole 132 is connected to the fan chamber 21. During the rotation of the wind wheel 5, a negative pressure is formed in the fan chamber 21. Under the action of the negative pressure of the fan chamber 21, the air flow in the compressor 6 enters the defrost air duct 11 through the air intake hole 131, and enters the fan chamber 21 from the air exhaust hole 132. Since the compressor 6 generates a large amount of heat during operation, the air flow entering the fan chamber 21 from the compressor chamber 22 is a hot air flow, which can be used to defrost the frost on the heat exchanger 3 in the fan chamber 21 and to defrost the ice on the chassis 1. In addition, the hot air flow can heat the chassis 1 and defrost the chassis 1 during the flow in the defrost air duct 11.

[0043] In the present application, the heat generated by the compressor 6 is used for defrosting and defrosting, and there is no need to add additional defrosting components, which can reduce the energy consumption of the air-conditioning outdoor unit 100 and reduce costs. In addition, the air conditioner does not need to be switched to the defrost mode, which can improve the user's comfort.

[0044] According to the air-conditioning outdoor unit 100 of the embodiment of the utility model, a defrost air duct 11 is arranged in the chassis 1, and an air intake hole 131 and an air exhaust hole 132 connected with the defrost air duct 11 are arranged on the chassis 1, the air intake hole 131 is connected with the compressor chamber 22, and the air exhaust hole 132 is connected with the fan chamber 21. Under the action of the wind wheel 5 in the fan chamber 21, the hot air flow in the compressor chamber 22 can be guided into the fan chamber 21, and the heat exchanger 3 in the fan chamber 21 and the chassis 1 can be defrosted without increasing additional power consumption and switching the air conditioner to the defrost mode, so that the power consumption of the air conditioner is reduced, the cost is reduced, and the comfort of the user is guaranteed.

[0045] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the air conditioner outdoor unit 100 further includes a heat exchanger 3, which is disposed in the fan chamber 21, and the exhaust hole 132 is located below the heat exchanger 3, and the exhaust hole 132 and the heat exchanger 3 are disposed opposite to each other in the vertical direction. The hot air flow discharged from the exhaust hole 132 can flow upward through the heat exchanger 3, so as to better realize the defrosting process of the heat exchanger 3, improve the efficiency and effect of defrosting, and ensure the reliability of the air conditioner.

[0046] Furthermore, if Figure 3-Figure 5 As shown, the exhaust holes 132 are multiple and spaced apart along the length direction of the heat exchanger 3. Thus, the heat exchanger 3 can be defrosted in the length direction of the exhaust holes 132 at the same time, thereby improving the defrosting efficiency and effect and ensuring the reliability of the air conditioner.

[0047] For example, in Figure 2 and 3 In the example shown, the heat exchanger 3 is generally L-shaped, and the heat exchanger 3 includes a first section 31 extending along the length direction of the chassis 1 and a second section 32 extending along the width direction of the chassis 1. The first section 31 and the second section 32 are connected, and there are four exhaust holes 132 arranged opposite to the first section 31, and the four exhaust holes 132 are arranged at intervals along the length direction of the first section 31, and there are two exhaust holes 132 opposite to the second section 32, and the two exhaust holes 132 are arranged at intervals along the length direction of the second section 32.

[0048] In some embodiments of the present invention, Figure 3As shown, the air conditioner outdoor unit 100 also includes an electric heating device 4, which is arranged in the defrosting air duct 11. When defrosting, the electric heating device 4 can be turned on, and auxiliary heating can be performed, and the hot air flow sucked from the compressor chamber 22 can be heated again, so as to increase the temperature of the air flow entering the fan chamber 21, thereby improving the defrosting and defrosting efficiency and effect of the heat exchanger 3 and the chassis 1, reducing the defrosting time, and ensuring the reliability of the air conditioner. In addition, the electric heating device 4 and the gas in the compressor chamber 22 heat the heat exchanger 3 and the chassis 1 together for defrosting and defrosting. Compared with the electric heating device alone, the energy consumption of the electric heating device 4 can be effectively reduced, and the user's use cost can be reduced. Moreover, the electric heating device 4 is arranged in the defrosting air duct 11 of the chassis 1, which can also improve the heating efficiency of the electric heating device 4, and can improve the defrosting efficiency of the air conditioner outdoor unit 100, thereby improving the use efficiency of the air conditioner.

[0049] The power of the electric heating device 4 can be set to 1000W, which can effectively assist in heating the airflow, so that the rising hot airflow heats the heat exchanger 3, thereby accelerating defrosting and removing ice from the chassis 1. In addition, the exhaust hole 132 is located on the fan cavity 21 side, and the air intake hole 131 is located on the compressor cavity 22 side. The air intake hole 131 can be used for the wiring of the electric heating device 4 while ventilating.

[0050] Furthermore, if Figure 3-Figure 5 As shown, the electric heating device 4 and the exhaust hole 132 are arranged opposite to each other in the vertical direction. Therefore, the airflow discharged from the exhaust hole 132 is all airflow heated by the electric heating device 4, thereby ensuring the defrosting efficiency and defrosting effect of the heat exchanger 3 and the defrosting efficiency and defrosting effect of the chassis 1.

[0051] In some embodiments of the present invention, there is one air intake hole 131, thereby ensuring the structural strength of the chassis 1 at the compressor cavity 22, ensuring the supporting effect for the compressor 6, and reducing the vibration of the compressor 6 transmitted to the chassis 1 to cause resonance of the chassis 1.

[0052] Optionally, the height of the defrost duct 11 in the vertical direction is 5mm-50mm. The height of the defrost duct 11 in the vertical direction is higher than 5mm, which is convenient for the setting of the electric heating device 4, etc. The height of the defrost duct 11 in the vertical direction is lower than 50mm, which can effectively reduce the energy consumption of the electric heating device 4, and at the same time improve the heating efficiency of the electric heating device 4, and ensure the ice-melting effect and efficiency of the chassis 1. As a result, the height of the defrost duct 11 in the vertical direction is 5mm-50mm, which is convenient for the setting of the electric heating device 4 and can ensure the ice-melting effect and efficiency of the chassis 1. For example, the height of the defrost duct 11 in the vertical direction is 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm or 45mm.

[0053] Optionally, the diameter of the air intake hole 131 is 5 mm-25 mm, which can facilitate the hot air flow in the compressor cavity 22 to flow into the defrosting air duct 11 through the air intake hole 131, and then flow into the fan cavity 21, and can ensure the structural strength of the chassis 1 of the compressor cavity 22, ensure the support effect of the compressor 6, and reduce the vibration of the compressor 6 transmitted to the chassis 1 to cause the resonance of the chassis 1. For example, the diameter of the air intake hole 131 is 5 mm, 10 mm, 15 mm, 20 mm or 25 mm, etc.

[0054] Optionally, the diameter of the exhaust hole 132 is 3 mm to 13 mm. This facilitates the airflow in the defrosting air duct 11 to flow into the fan chamber 21 through the exhaust hole 132, thereby achieving defrosting and ice-melting treatment of the heat exchanger 3 and the chassis 1, and ensuring the structural strength of the chassis 1 on the fan chamber 21 side. For example, the diameter of the exhaust hole 132 is 5 mm, 8 mm, 10 mm or 12 mm, etc.
