Embodiment 1

[0069] An air conditioner outdoor unit, comprising: a casing 1 and a fan 3, such as figure 1 with figure 2 shown.

[0070] Specifically, the casing 1 is provided with a first air exchange port 11 and a second air exchange port 12, such as figure 1 with figure 2 shown.

[0071] The fan 3 is arranged in the casing 1, and is located between the first air exchange port 11 and the second air exchange port 12, as figure 1 with figure 2 shown.

[0072] Wherein, the fan 3 includes a motor, a first fan 32 and a second fan 33 . The motor includes two rotors 312 that rotate independently of each other and a first output shaft 3131 and a second output shaft 3132 respectively connected to the two rotors 312, as Figure 7 with Figure 8 shown. The first output shaft 3131 and the second output shaft 3132 respectively protrude toward the same side of the motor axial direction along the axial direction of the motor, and the first output shaft 3131 and the second output shaft 3132 a...

Embodiment 2

[0104] The difference from Embodiment 1 is that the variable frequency axial air gap motor 31 includes two stators 311 and two rotors 312, and the two stators 311 correspond to the two rotors 312 one by one, as Figure 9 shown. Each stator 311 includes a stator core 3111 and a winding 3115, such as Figure 10 As shown, one axial end of each stator core 3111 is provided with stator teeth protruding along its axial direction, and the corresponding windings 3115 are wound on the stator teeth, and each rotor 312 is arranged on the axis of the corresponding stator 311. to one side, and forms an axial air gap with the corresponding stator 311.

[0105] This solution uses the cooperation of two stators 311, two rotors 312 and two rotating shafts to realize the dual power independent output of one motor, which is equivalent to integrating the internal structures of the two motors. Compared with two independent motors , also reduces the number of mounting frames 5, reduces the diffic...

Embodiment 3

[0110] The difference from Embodiment 1 or Embodiment 2 is that: the axis of fan 3 is along the horizontal direction, such as figure 1 shown.

[0111] The axis of the fan 3 extends along the horizontal direction, the air supply direction of the first fan 32 and the second fan 33 is the horizontal direction, and the required installation surface of the fan 3 is a vertical surface, which is conducive to the installation of the outdoor unit of the air conditioner on the outside of the wall. Considering the influence of gravity, this solution is more suitable for outdoor units of air conditioners with low power requirements.

Abstract

The invention provides an air conditioner outdoor unit and air conditioning equipment. The air conditioner outdoor unit comprises a machine shell and a draught fan, wherein the machine shell is provided with a first air exchange opening and a second air exchange opening; and the draught fan is arranged in the machine shell and located between the first air exchange opening and the second air exchange opening, the draught fan comprises a motor, a first fan and a second fan, the motor comprises two rotors which rotate independently, a first output shaft and a second output shaft, and the first output shaft and the second output shaft are correspondingly connected with the two rotors, the first output shaft and the second output shaft correspondingly protrude towards the same side, facing theaxial direction of the motor, in the axial direction of the motor and are correspondingly and fixedly connected with the first fan and the second fan, and the first output shaft and the second outputshaft are used for driving the first fan and the second fan to rotate independently. The motor is used for driving the first fan and the second fan to rotate at the same speed or different speeds orin the same direction or different directions, so that the air conditioner outdoor unit has the functions of heat exchange, self-cleaning, self-drying, headwind starting and the like, and has the advantages of being easy to install, small in size specification, large in air volume, high in energy efficiency, low in manufacturing cost and the like.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner and an air conditioner including the outdoor unit of an air conditioner. Background technique [0002] The outdoor units of air conditioners on the market are usually single-stage fans.
