According to the embodiment of the present invention, as shown in fig. 1 and fig. 2, the outdoor unit 100 of the present invention includes a casing 10, a bracket 20, a first motor 30, a second motor 50, a first wind wheel 40 and a second wind wheel 60, wherein the bracket 20 is the above bracket 20 for mounting the motor.

Specifically, the housing 10 has an air inlet side (not shown), an air outlet side (not shown), and an air duct (not shown) connected between the air inlet side and the air outlet side. When the outdoor unit 100 operates, air enters the air duct from the air inlet side, flows to the air outlet side, and is blown out of the casing 10.

As shown in fig. 2, the bracket 20 is installed in the air duct, the first motor 30 is installed on the motor installation portion 21 and is located on one side of the bracket 20 close to the air inlet side, the second motor 50 is installed on the motor installation portion 21 and is located on one side of the bracket 20 close to the air outlet side, the first wind wheel 40 is located in the casing 10 and connected to the first motor 30, and the second wind wheel 60 is located in the casing 10 and connected to the second motor 50.

It can be understood that, by arranging the first motor 30 and the second motor 50, after the air passes through the first wind wheel 40 and the second wind wheel 60 in sequence and is accelerated, compared with the air conditioner outdoor unit 100 with a single wind wheel, in the same time, the flow rate of the air in the air conditioner outdoor unit 100 is faster, the air volume can be larger, and the efficiency is higher. In addition, according to the air conditioner outdoor unit 100 of the present application, the energy conversion rate of the present application is 70% when the same air volume is output, as compared to the air conditioner outdoor unit 100 of the related art, and the energy conversion rate of the related art is about 60%, so that the air conditioner outdoor unit 100 of the present application has lower power consumption and higher energy efficiency.

Therefore, according to the present invention, the outdoor unit 100 of the air conditioner has the first motor 30 and the second motor 50, and the first motor 30 and the second motor 50 work together to improve the wind speed and the energy efficiency.

as shown in fig. 2, the outdoor unit 100 further includes a heat exchanger 70 therein, and the heat exchanger 70 is disposed on an air inlet side, an air outlet side, or in an air duct of the casing 10. For example, the heat exchanger 70 is disposed at an air inlet side of the casing 10, and when the outdoor unit 100 of the air conditioner operates, air enters the air duct through the air inlet side and after heat exchange (for example, heating or cooling) by the heat exchanger 70, and then the air after heat exchange flows from the air duct to an air outlet side, and finally is blown to the outdoor space through the air outlet side. Of course, the heat exchanger 70 may also be disposed at the air outlet side of the casing 10, when the outdoor unit 100 of the air conditioner operates, air enters the air duct through the air inlet side, and then flows from the air duct to the air outlet side, and the air is blown to the outdoor space from the air outlet side after passing through the heat exchanger 70 at the air outlet side to exchange heat (e.g., cool or heat). In addition, the heat exchanger 70 may be disposed in the air duct, and when the outdoor unit 100 of the air conditioner operates, air enters the air duct through the air inlet side, and the air entering the air duct flows to the air outlet side after heat exchange (e.g., cooling or heating) by the heat exchanger 70, and then is blown to the outdoor space from the air outlet side.

Of course, the above embodiments are only illustrative and should not be construed as limiting the scope of the present invention, for example, when the outdoor unit 100 is operated, the heat exchanger 70 may not be operated, in other words, only the first motor 30 and the second motor 50 are operated, and at this time, the outdoor unit 100 functions as a fan.

in the above embodiment, the first motor 30 and the second motor 50 may rotate in the same direction or in opposite directions, and the rotation direction thereof is related to the arrangement of the blades of the wind rotor, and regardless of the form of the first wind rotor 40 and the second wind rotor 60, the second wind rotor 60 always receives the wind from the first wind rotor 40 and accelerates it, thereby achieving the effect of improving energy efficiency and wind speed.

The technical scheme of the utility model is through introducing two axial flow wind wheels that set up relatively in the heat transfer wind channel of outdoor unit of air conditioner 100, and make the direction of rotation of the first wind wheel 40 blade opposite with the second wind wheel 60, so, two axial flow fan wind-guiding jointly, increased the amount of wind, and the blade rotation of first wind wheel 40 and second wind wheel 60 forms the counter-rotating air current, the wind field that produces respectively in heat transfer wind channel wall department offsets each other, thereby also effectively reduced respective aerodynamic noise; that is, the utility model discloses technical scheme has increased air condensing units 100's the amount of wind on the one hand, has improved air condensing units 100's heat exchange efficiency then, and on the other hand has reduced air condensing units 100's noise at work.

The first wind wheel 40 and the second wind wheel 60 are coaxially arranged, and the rotating direction of the first wind wheel 40 when the airflow is guided to the air outlet side from the air inlet side is opposite to the rotating direction of the second wind wheel 60 when the airflow is guided to the air outlet side from the air inlet side. The first wind wheel 40 and the second wind wheel 60 are engaged with each other to adjust the blowing range of the air conditioner outdoor unit 100.

When the outdoor unit 100 of the air conditioner is operated, the first wind wheel 40 rotates to guide the airflow into the casing 10 from the air inlet and to the front of the first wind wheel 40. At this time, if the blowing distance needs to be increased, the rotation speed of the second wind rotor 60 may be increased. If the air supply distance needs to be reduced, the rotation speed of second wind turbine 60 may be reduced, or the operation of second wind turbine 60 may be stopped, or second wind turbine 60 may be controlled to rotate in the reverse direction (relative to the rotation direction of second wind turbine 60 when supplying air). Of course, in order to adjust the air supply distance, the rotation speeds of first wind turbine 40 and second wind turbine 60 may also be adjusted according to actual needs, for example, the rotation speeds of first wind turbine 40 and second wind turbine 60 are increased simultaneously; it is also possible to reduce the rotational speed of first rotor 40 and increase the rotational speed of second rotor 60; the rotation speed of the first wind wheel 40 and the rotation speed of the second wind wheel 60 can be reduced at the same time; the rotational speed of first rotor 40 may also be increased and the rotational speed of second rotor 60 may be decreased.

Thus, the operation of the first motor 30 and the second motor 50 may be independent of each other. The user may individually adjust the rotational speed of first rotor 40 and the rotational speed of second rotor 60, for example, individually increasing or decreasing or stopping first rotor 40; the second wind wheel 60 is individually increased or decreased or stopped or the second wind wheel 60 is controlled to rotate reversely. Of course, the two axial flow wind wheels can also be controlled to rotate simultaneously, for example, the two axial flow wind wheels are controlled to rotate in an accelerated mode simultaneously, or the two axial flow wind wheels are controlled to rotate in a decelerated mode simultaneously. At this time, the rotation speeds of the two fan assemblies 200 may be the same or different. For example, when the two rotors are controlled to rotate simultaneously, the rotation speed of first rotor 40 may be higher than that of second rotor 60, or the rotation speed of first rotor 40 may be lower than that of second rotor 60, or the rotation speed of one of the rotors may be reduced to 0 when the two rotors are controlled to operate at reduced speed.

The technical scheme of the utility model through set up two axial compressor wind wheels in air condensing units 100, through the rotational speed of adjusting the diaxon flow wind wheel, realize the increase or the reduction of the air supply distance of axial compressor wind wheel to air condensing units 100's air supply scope has been improved. Meanwhile, since the two axial flow wind wheels are fixed on the air inlet side and the air outlet side of the casing 10 by the same bracket 20, the thickness of the bracket 20 is effectively reduced, thereby reducing the overall thickness of the outdoor unit 100.

In some embodiments, as shown in fig. 2 in combination with fig. 3 and 4, one end of the bracket 20 is connected to the top wall 11 of the housing 10, the bottom wall 12 of the housing 10, a side wall (not shown) of the housing 10, the front panel 13 of the housing 10, a back panel (not shown) of the housing 10, or the heat exchanger 70, and the other end of the bracket 20 is connected to the top wall 11 of the housing 10, the bottom wall 12 of the housing 10, the side wall (not shown) of the housing 10, the front panel 13 of the housing 10, the back panel of the housing 10, or the heat exchanger 70.

In some alternative embodiments, the bracket 20 is connected to the top wall 11 and the bottom wall 12 of the housing 10 at two ends.

In some alternative embodiments, the bracket 20 is connected to the front panel 13 of the housing 10 at one end and to the bottom wall 12 of the housing 10 at the other end.

In some alternative embodiments, the bracket 20 is connected at two ends to the opposite sidewalls of the housing 10.

In some alternative embodiments, the bracket 20 is connected to the top wall 11 of the housing 10 at one end and connected to the front panel 13 of the housing 10 at the other end.

In some alternative embodiments, the bracket 20 is connected to the front panel 13 of the housing 10 at one end and to the back panel or heat exchanger 70 of the housing 10 at the other end.

In alternative embodiments, the bracket 20 is connected to the front panel 13 of the housing 10 at both ends.

In some alternative embodiments, both ends of the bracket 20 are connected to the back plate of the housing 10.

From the above, the arrangement form of the bracket 20 is not particularly limited as long as the bracket 20 can provide support for the first motor 30, the first wind wheel 40, the second motor 50 and the second wind wheel 60 without interfering with the rotation of the wind wheels or other working components of the outdoor unit 100.

For example, in one embodiment, the upper end of the bracket 20 is screwed to the front panel 13 of the housing 10, and the lower end of the bracket 20 is supported on the bottom wall 12 of the housing 10 and screwed to the bottom wall 12 of the housing 10.

considering that the first wind wheel 40 and the second wind wheel 60 generate resonance between blades when rotating, for this reason, the number of blades of the first wind wheel 40 and the number of blades of the second wind wheel 60 are prime numbers to eliminate the resonance phenomenon that may occur during operation.
