As shown in fig. 1 to 3, according to a first aspect of an embodiment of the present application, an air conditioner outdoor unit is provided, which includes: a housing 110, wherein the housing 110 is provided with an air inlet side and an air outlet side, and an air channel is formed between the air inlet side and the air outlet side; a driving unit 120 provided in the housing 110, the driving unit 120 including: a single-shaft motor 121 and a transmission unit 122, the transmission unit 122 being connected to the single-shaft motor 121; fan blades 130 connected to the transmission part 122, located in the air duct, and respectively disposed at both sides of the single-shaft motor 121; the transmission part 122 is used for adjusting the fan blades 130 at two sides of the single-shaft motor 121 to rotate in opposite directions so as to form a counter-rotating structure.
The air conditioner outdoor unit provided in the embodiment of the present application is provided with a housing 110, a driving assembly 120 and fan blades 130. Wherein, the housing 110 is provided with an air inlet side and an air outlet side, and an air channel is formed between the air inlet side and the air outlet side. The driving assembly 120 is disposed in the housing 110, and the driving assembly 120 includes a single-shaft motor 121 and a transmission portion 122, wherein the transmission portion 122 is connected to the single-shaft motor 121. The fan blades 130 are connected to the transmission part 122, and the transmission part 122 transmits the output power of the single-shaft motor 121 to the fan blades 130, so that the fan blades 130 rotate, and the rotation direction of the fan blades 130 is adjusted, so that the fan blades 130 on two sides of the single-shaft motor 121 rotate in opposite directions, thereby forming a disrotatory structure, generating larger air quantity, improving the air supply effect and improving the energy efficiency. The fan blade 130 can be driven to supply air to the rotary structure through the single-shaft motor 121, so that the whole structure is simple, the number of parts is reduced, and the production cost and the assembly difficulty are reduced. And the occupied internal space of the air conditioner external unit is less, the volume of the air conditioner external unit is reduced, and the rationality of the space layout is improved.
It will be appreciated that in the counter-rotating configuration, the blades 130 on either side of the single axis motor 121 rotate in opposite directions. Specifically, the fan 130 far from the panel 111 is a primary fan, the fan 130 near the panel 111 is a secondary fan, and the air flow is boosted by the primary fan and then discharged from the air outlet 1111. The circumferential tangential velocity formed when the air flow passes through the first-stage fan blade is opposite to the circumferential tangential velocity formed by the second-stage fan blade, so that the air flow and the second-stage fan blade can be partially or completely offset to form straight air flow in the axial direction, even if as much air flow as possible can be blown out along the axial direction of the disrotatory structure, the air supply distance is increased, the air supply quantity is increased, and the heat exchange effect is improved. Therefore, compared with the related art, on the premise of realizing the same air supply effect, the single-shaft motor 121 can drive the disrotatory structure to run at a lower rotating speed, so that the working noise of the disrotatory structure is reduced, the overall working noise of the air conditioner external unit is reduced, the noise pollution is reduced, and the user experience is improved.
It can be appreciated that, compared to a single cross flow wind wheel, axial flow wind wheel or diagonal flow wind wheel, the blades 130 on both sides of the single shaft motor 121 in the disrotatory structure can rotate simultaneously, so that the air supply amount and the air supply efficiency of the disrotatory structure are the greatest on the premise that the driving assembly 120 consumes the same power. Therefore, the power consumption of the rotating structure is also the lowest on the premise of meeting the same air supply amount requirement. Therefore, the dual-purpose air supply device has the dual functions of improving the air supply efficiency and reducing the energy consumption, and has extremely strong practical performance.
Illustratively, the distances between the fan blades 130 on two sides of the single-shaft motor 121 and the single-shaft motor 121 are equal, which is more beneficial to counteracting the rotation speed and ensuring the axial air supply effect. Therefore, the process parameters of the fan blades 130 at both sides of the single-axis motor 121 and the transmission shaft 131 of the fan blades 130 are the same. The method can be used for batch production, does not need to change process parameters for independent processing, and improves the production efficiency.
In some examples, as shown in fig. 1 to 3, the transmission part 122 includes: a first transmission member connected to an output shaft of the single-shaft motor 121; the second transmission member is connected to the fan blade 130 and the first transmission member respectively; a third transmission member connected to the fan blade 130 and the first transmission member, respectively; the second transmission member and the third transmission member are respectively positioned at two sides of the first transmission member, and the axes of the second transmission member and the third transmission member are collinear and have opposite transmission directions.
It is understood that the transmission part 122 is provided with a first transmission member, a second transmission member, and a third transmission member. The first transmission member is connected to the output shaft of the single-shaft motor 121, the second transmission member is connected to the transmission shaft 131 of the fan blade 130 and the first transmission member, and the third transmission member is connected to the transmission shaft 131 of the fan blade 130 and the first transmission member. And the second transmission member and the third transmission member are respectively positioned at two sides of the first transmission member to respectively correspond to the fan blades 130 at two sides of the single-shaft motor 121. So configured, the power generated by the single-shaft motor 121 is transmitted to the first transmission member through the output shaft, and the first transmission member transmits the power to the second transmission member and the third transmission member, respectively, so that the second transmission member drives the transmission shaft 131 and the fan blade 130 at one side of the single-shaft motor 121 to rotate in the first direction; the third driving member drives the driving shaft 131 and the fan blade 130 at the other side of the single-shaft motor 121 to rotate in the second direction, and the first direction is opposite to the second direction. Therefore, only one single-shaft motor 121 is matched with the first transmission piece, the second transmission piece and the third transmission piece, and the air supply of the disrotatory structure can be driven, so that the whole structure is simple, the number of parts is reduced, and the production cost and the assembly difficulty are reduced. And the occupied internal space of the air conditioner external unit is less, the volume of the air conditioner external unit is reduced, and the rationality of the space layout is improved.
It can be understood that the axes of the second transmission member and the third transmission member are collinear, so that the fan blades 130 and the transmission shafts 131 on two sides of the single-shaft motor 121 are collinear, which is more beneficial to counteracting the rotation speed and ensuring the axial air supply effect.
In some examples, as shown in fig. 1 to 3, the first transmission member is a first bevel gear 1221, the second transmission member is a second bevel gear 1222, the third transmission member is a third bevel gear 1223, and the second bevel gear 1222 and the third bevel gear 1223 are respectively meshed with the first bevel gear 1221; wherein the direction of the teeth rotation of the second bevel gear 1222 is opposite to the direction of the teeth rotation of the third bevel gear 1223.
It will be appreciated that bevel gears may alternatively be used to adjust the direction of power transfer. Specifically, the first transmission member may be selected from a first bevel gear 1221, the second transmission member may be selected from a second bevel gear 1222, and the third transmission member may be selected from a third bevel gear 1223. Wherein, the first bevel gear 1221 is connected to the output shaft of the single-shaft motor 121, the second bevel gear 1222 is connected to the transmission shaft 131 of the fan blade 130 on one side of the single-shaft motor 121 and engaged with the first bevel gear 1221, and the third bevel gear 1223 is connected to the transmission shaft 131 of the fan blade 130 on the other side of the single-shaft motor 121 and engaged with the first bevel gear 1221. So configured, the power generated by the single-shaft motor 121 is transmitted to the first bevel gear 1221 through the output shaft, the first bevel gear 1221 transmits the power to the second bevel gear 1222 and the third bevel gear 1223, respectively, and the power transmission direction is changed due to the engagement characteristic between the bevel gears, so that the second bevel gear 1222 drives the transmission shaft 131 and the fan blades 130 at one side of the single-shaft motor 121 to rotate in the first direction; the third bevel gear 1223 drives the transmission shaft 131 and the fan blade 130 at the other side of the single-shaft motor 121 to rotate in the second direction, and the first direction is opposite to the second direction. Therefore, only one single-shaft motor 121 is matched with the bevel gear set, and the air supply of the disrotatory structure can be driven, so that the whole structure is simple, the number of parts is reduced, and the production cost and the assembly difficulty are reduced. And the occupied internal space of the air conditioner external unit is less, the volume of the air conditioner external unit is reduced, and the rationality of the space layout is improved.
In some examples, the rotation speeds of the fan blades 130 disposed at both sides of the single-axis motor 121 are the same.
It will be appreciated that in order to ensure that the rotating structure is capable of completely counteracting the rotational speed generated by the rotation of the fan blades 130, it is necessary that the rotational speeds of the fan blades 130 on both sides of the single-shaft motor 121 are the same and the directions of the rotation are opposite. To ensure that the rotational speed of the fan blades 130 on both sides of the single shaft motor 121 is the same, the second and third bevel gears 1222 and 1223 may be provided with the same process parameters. That is, the second bevel gear 1222 and the third bevel gear 1223 mesh with the first bevel gear 1221 in the same number of teeth, and the set number of teeth, pitch, and rotation angle of the teeth are the same, thereby ensuring that the transmission power of the second bevel gear 1222 and the third bevel gear 1223 are equal.
In some examples, the minimum axial distance between the blades 130 disposed on both sides of the single-axis motor 121 is greater than or equal to 5mm.
It will be appreciated that in order to make the overall structure of the air conditioner external unit more compact and reduce the overall size of the air conditioner external unit, the fan blades 130 on both sides of the single shaft motor 121 should have an appropriate axial distance. If the axial distance between the blades 130 on both sides of the single-shaft motor 121 is too small, the installation is inconvenient, and the counter-rotating structure and the installation process of the single-shaft motor 121 and the transmission part 122 are easy to collide and damage parts. Accordingly, the minimum axial spacing of the fan blades 130 on both sides of the single-axis motor 121 is set to be greater than or equal to 5mm.
Illustratively, the axial spacing of the blades 130 on either side of the single axis motor 121 may range from 5mm to 30mm. The axial distance between the fan blades 130 on two sides of the single-shaft motor 121 is prevented from being too large, so that more space is occupied in the shell 110, the volume of the air conditioner outdoor unit is large, the appearance is bulkier, and the appearance attractiveness is affected.
In some examples, as shown in fig. 1 and 2, the air conditioner external unit further includes: the connection base 140 is disposed on the bottom plate 112 of the housing 110, and the single-shaft motor 121 is connected to the connection base 140.

The air guide cover 150 is formed with a plurality of hollows to ensure smooth circulation of air. On the one hand, the hollowed-out parts can prevent foreign matters and part of dust from entering the shell 110, so that normal use of parts in the shell 110 is affected, the protectiveness is improved, and the service life of the air conditioner outdoor unit is prolonged. On the other hand, can dispel the heat better through the fretwork, improve radiating efficiency, guarantee the air conditioner outer can last the use for a long time, improve the reliability.
