An air conditioner outdoor unit according to an embodiment of the present invention is provided, and will be specifically described with reference to fig. 1 to 10.
In an embodiment of the present invention, the outdoor unit of an air conditioner includes:
the air conditioner comprises a shell 100, wherein the shell 100 is provided with an air inlet 101 and an air outlet 101;
a motor 200 installed in the housing 100, the motor 200 having a motor shaft 210;
the first wind wheel 300 is mounted on the motor shaft 210, and the first wind wheel 300 is used for driving airflow to flow into the housing 100 from the air inlet and flow out from the air outlet 101; and the number of the first and second groups,
the second wind wheel 400 is installed in the housing 100 and located in the airflow flowing direction, the second wind wheel 400 is a driven wind wheel, and the motor 200 drives the first wind wheel 300 to rotate and generate an airflow for driving the second wind wheel 400 to rotate.
In this embodiment, as shown in fig. 1 and fig. 2, the housing 100 includes a front panel, and the front panel is provided with an air outlet 101, it can be understood that a flow direction of the air flow in the housing 100 is from the air inlet to the air outlet 101. The heat exchanger 800 is further installed in the housing 100, optionally, the heat exchanger 800 is disposed corresponding to the air inlet, and the motor 200 drives the first wind wheel 300 to rotate, so that the first wind wheel 300 drives the airflow to enter the housing 100 from the air inlet, then the airflow flows through the heat exchanger 800 to exchange heat, and finally the airflow is blown out from the air outlet 101. It can be understood that, when the air conditioner indoor unit corresponding to the air conditioner outdoor unit is in the cooling mode, the heat exchanger 800 in the air conditioner outdoor unit is a condenser, and the wind wheel dissipates heat by driving airflow. In order to improve the heat exchange efficiency of the heat exchanger 800, the air volume flowing through the heat exchanger 800 may be increased. In the prior art, an air duct system of an air conditioner outdoor unit usually adopts a single-motor single-wind-wheel air duct system, and if the air volume needs to be increased, the rotating speed of a motor can only be increased, so that the noise is increased; some air-conditioning outdoor units adopt a double-motor double-wind-wheel air duct system, although the air volume is obviously improved, the double motors are adopted, the defect of high noise still exists, the structure and the control are complex, and the occupied space is large. It should be noted that, if the outdoor unit of the air conditioner adopts the air duct system in which the single motor simultaneously drives the two wind wheels, the single motor needs to simultaneously drive the two wind wheels to rotate, so that the motor load is large, the reliability is poor, and the noise is still large.
The invention provides an outdoor unit of an air conditioner, wherein a first wind wheel 300 and a second wind wheel 400 are arranged in a shell 100, the first wind wheel 300 is a driving wind wheel and is driven by a motor 200 to rotate, and the second wind wheel 400 is a driven wind wheel and is driven by airflow generated by the rotation of the first wind wheel 300 to rotate. Compared with the existing single-motor 200 single-wind-wheel air duct system, the single-motor 200 single-wind-wheel air duct system has the advantages that one wind wheel is added under the same rotating speed, so that the air volume of the air duct system can be remarkably increased; compared with a double-motor 200 and double-wind wheel air duct system, the double-motor 200 and double-wind wheel air duct system has the advantages that one motor 200 is omitted, the noise of the motor 200 is reduced, meanwhile, the structure and the control are simple, and further, the manufacturing and installation cost is reduced. In addition, compared with an air duct system in which the single motor 200 drives two wind wheels simultaneously, the wind power generation device can reduce the load of the motor 200, further reduce the noise of the motor 200, and simultaneously ensure the air volume in the air duct system. Therefore, the invention can effectively reduce the noise generated by the operation of the air conditioner outdoor unit while improving the air volume of the air conditioner outdoor unit.
In one embodiment, as shown in fig. 3 and 4, the blades of the first wind wheel 300 rotate in the opposite direction to the blades of the second wind wheel 400, so that the second wind wheel 400 rotates in the opposite direction with respect to the first wind wheel 300 under the driving of the airflow generated by the first wind wheel 300, that is, the opposite rotation of the front and rear wind wheels is realized. In the embodiment, the double-wind wheel contra-rotating structure is adopted, so that the airflow deviated from the axial direction can be corrected, and the airflows of the two wind wheels are connected in series as far as possible along the axial direction and then blown out in the same direction. It is understood that in other embodiments, the rotation direction of the blades of the first wind wheel 300 is the same as that of the blades of the second wind wheel 400, so that the second wind wheel 400 rotates in the same direction relative to the first wind wheel 300 under the driving of the airflow generated by the first wind wheel 300, and the air volume can be increased and the noise can be reduced. However, compared with the air conditioner outdoor unit adopting the structure of the double wind wheels rotating oppositely, the air conditioner outdoor unit can intensively blow out the air from the axial direction, and the air volume is improved more obviously, so that the noise generated by the operation of the air conditioner outdoor unit is lower under the condition of the same air volume.
Further, as shown in fig. 4 and 5, the motor shaft 210 is mounted with a bearing 500, and the second wind wheel 400 is mounted with the bearing 500. In the present embodiment, the bearing 500 is a rolling bearing 500. Specifically, the motor shaft 210 is provided with a first fastening thread 211 and a second fastening thread 212, wherein the first fastening thread 211 is used for the first wind wheel 300 to be directly mounted, and the second fastening thread 212 is used for the rolling bearing 500 to be mounted. Specifically, the rolling bearing 500 is mounted on the second fastening screw 212, and then the second wind wheel 400 is mounted on the rolling bearing 500 and finally locked with the nut 600, so that the second wind wheel 400 can rotate with respect to the motor shaft 210 without rotating together with the motor shaft 210. It can be understood that, in this embodiment, the second wind wheel 400 is sleeved on the motor shaft 210, and the motor shaft 210 only provides a limiting function for the second wind wheel 400, but does not provide a direct driving force for the rotation thereof. Of course, in other embodiments, the housing 100 is provided with a wind wheel bracket, and the second wind wheel 400 may also be provided on the wind wheel bracket without being limited to the motor shaft 210, and the second wind wheel 400 may be provided coaxially with the first wind wheel 300. Compared with other embodiments, the technical scheme of the embodiment has the advantages of simple structure, small occupied space and capability of saving materials and installation cost.
In an embodiment, the second wind wheel 400 is located between the air outlet 101 and the first wind wheel 300. That is, the second wind rotor 400 (driven wind rotor) is located downstream of the first wind rotor 300 (driving wind rotor) in the flow direction of the airflow. It can be understood that after the motor 200 drives the first wind wheel 300 to rotate, the first wind wheel 300 blows the airflow to the second wind wheel 400, and the second wind wheel 400 rotates along with the airflow.
In the present embodiment, as shown in fig. 2 and 3, the first wind wheel 300 is located between the wind outlet 101 and the second wind wheel 400. That is, the second wind rotor 400 (driven wind rotor) is located upstream of the first wind rotor 300 (driving wind rotor) in the flow direction of the airflow. It can be understood that after the first wind wheel 300 is driven by the motor 200 to rotate, an intake pressure is generated upstream (i.e. behind) the first wind wheel 300, and the second wind wheel 400 is driven by the air pressure to rotate along with the first wind wheel 300 and wind out in the same direction. It can be understood that the produced amount of wind of initiative wind wheel is generally bigger than driven wind wheel, compare in a last embodiment, this embodiment with initiative wind wheel than driven wind wheel be closer to air outlet 101 setting, more be favorable to initiative wind wheel to send out air outlet 101 with the air current to the air output of further increase air outlet 101, thereby increase whole air duct system's amount of wind.
Further, as shown in fig. 3 and 4, the diameter of the first wind wheel 300 is greater than or equal to the diameter of the second wind wheel 400. The diameter of the wind wheel can influence the air outlet quantity of the wind wheel and is in positive correlation. And first wind wheel 300 is the initiative wind wheel in this embodiment, and second wind wheel 400 is driven wind wheel, and first wind wheel 300 needs to drive second wind wheel 400 rotatory promptly, and consequently, the diameter of first wind wheel 300 is more than or equal to the diameter of second wind wheel 400, is favorable to first wind wheel 300 to produce bigger wind pressure to help driving second wind wheel 400 to rotate.
Further, as shown in FIG. 4, the axial blade height H of the first wind wheel 3001Is greater than or equal to the axial blade height H of the second wind wheel 4002. Similarly, the axial blade height of the wind wheel also affects the wind output of the wind wheel and is in positive correlation. Therefore, the axial blade height of the first wind wheel 300 is greater than or equal to the axial blade height of the second wind wheel 400, which is beneficial to the first wind wheel 300 to generate larger wind pressure, thereby being beneficial to driving the second wind wheel 400 to rotate.
Further, the blade area of the first wind wheel 300 is greater than or equal to the blade area of the second wind wheel 400. Similarly, the fan blade area of the wind wheel also affects the wind outlet volume of the wind wheel, and is in positive correlation. Therefore, the area of the first wind wheel 300 is greater than or equal to the area of the second wind wheel 400, which is beneficial to the first wind wheel 300 to generate larger wind pressure, thereby being beneficial to driving the second wind wheel 400 to rotate.
In this embodiment, as shown in fig. 3, a distance d between the first wind wheel 300 and the second wind wheel 400 is 8-15 mm. It can be understood that the first wind wheel 300 and the second wind wheel 400 are coaxially arranged at intervals, and the distance between the first wind wheel 300 and the second wind wheel 400 is too far and too close, which is not beneficial to the airflow generated by the first wind wheel 300 to drive the second wind wheel 400 to rotate, and the occupied space is also large; when the distance is too close, the two wind wheels may interfere with each other when rotating, which is not favorable for the long-term stable operation of the outdoor unit of the air conditioner.
In this embodiment, as shown in fig. 3 to 5, the motor 200 is located between the second wind wheel 400 and the wind inlet. Specifically, the motor shaft 210 is located at one end of the motor 200 facing the air outlet 101, and in the flowing direction of the airflow, the motor 200, the second fastening screw 212, and the first fastening screw 211 are sequentially arranged, so that the motor 200, the second wind wheel 400, and the first wind wheel 300 are sequentially arranged.
Further, as shown in fig. 1 and 2, the heat exchanger 800 is disposed corresponding to and near the air inlet, and the motor 200 is located between the second wind wheel 400 and the heat exchanger 800. Specifically, the motor 200 is mounted on the motor bracket 700, and both the motor 200 and the motor bracket 700 are located between the second wind wheel 400 and the heat exchanger 800. It can be understood that, in the present embodiment, the motor 200 and the motor bracket 700 are disposed near the rear of the casing 100, so that the internal space of the casing 100 can be fully utilized, and the space utilization rate in the casing 100 can be improved; the distance between the first wind wheel 300 and the air outlet 101 can be shortened, and the air outlet volume can be increased; and, shortening the distance between the first wind wheel 300 and the second wind wheel 400, ensuring that the second wind wheel 400 can rotate under the driving of the airflow of the first wind wheel 300.
In another embodiment, as shown in fig. 6 to 8, the motor 200 is located between the air outlet 101 and the first wind wheel 300. Specifically, the motor 200 is mounted on the motor support 700, and both the motor 200 and the motor support 700 are located between the air outlet 101 and the first wind wheel 300. The motor shaft 210 is located at one end of the motor 200 facing the air inlet, and the second fastening screw 212, the first fastening screw 211 and the motor 200 are sequentially arranged in the flowing direction of the air flow, so that the first wind wheel 300, the second wind wheel 400 and the motor 200 are sequentially arranged.
In yet another embodiment, as shown in fig. 9-10, the electric machine 200 is located between the first wind rotor 300 and the second wind rotor 400. Specifically, the motor 200 is mounted on the motor bracket 700, and the motor 200 and the motor bracket 700 are both located between the first wind wheel 300 and the second wind wheel 400. Two ends of the motor 200 extend out of the two motor shafts 210 towards the air inlet and the air outlet 101 respectively, and the second fastening threads 212, the motor 200 and the first fastening threads 211 are sequentially arranged in the flowing direction of the airflow, so that the second wind wheel 400, the motor 200 and the first wind wheel 300 are sequentially arranged.
