The motor 22 may be a dual-shaft motor, but is not limited thereto. Here, a two-shaft motor is understood to be a motor 22 having two driving shafts 220, and the two driving shafts 220 may be respectively connected to the two wind wheels 21 in a one-to-one correspondence manner, that is, one driving shaft 220 (directly or indirectly) drives the first wind wheel 210a to rotate, and the other driving shaft 220 (directly or indirectly) drives the second wind wheel 210b to rotate. The two driving shafts 220 may be respectively disposed at two axial sides of the dual-shaft motor, the two driving shafts 220 may be disposed coaxially or disposed non-coaxially, and the axes of the two driving shafts 220 may be overlapped or parallel, but are not limited thereto.

As shown in fig. 5, 6, 8 and 20, the bearing seat assembly 3 includes a bearing seat 31, and an end of at least one wind turbine 21 away from the motor 22 is rotatably disposed on the base 1 through the bearing seat 31, that is, an end of one of the two wind turbines 21 away from the motor 22 is rotatably disposed on the base 1 through the bearing seat 31, or an end of each wind turbine 21 away from the motor 22 is rotatably disposed on the base 1 through the bearing seat 31, that is, an end of the first wind turbine 210a away from the motor 22 is rotatably disposed on the base 1 through the bearing seat 31, and/or an end of the second wind turbine 210b away from the motor 22 is rotatably disposed on the base 1 through the bearing seat 31. It is understood that the bearing housing 31 may be one or more. In the description of the present invention, "a plurality" means two or more.
When one end of the first wind wheel 210a, which is far away from the motor 22, is rotatably arranged on the base 1 through the bearing seat 31, one end of the first wind wheel 210a, which is close to the motor 22, is connected with the motor 22 to be driven to rotate by the motor 22, and then the two axial ends of the first wind wheel 210a are respectively supported by the motor 22 and the base 1, so that coaxiality of the first wind wheel 210a in the rotating process is ensured, shaking of the first wind wheel 210a in the rotating process is further reduced, rotation stability of the first wind wheel 210a is ensured, good dynamic balance of the first wind wheel 210a is further ensured, stress of the driving shaft 220 is reduced, and use reliability of the motor 22 is improved.
When one end of the second wind wheel 210b, which is far away from the motor 22, is rotatably arranged on the base 1 through the bearing seat 31, one end of the second wind wheel 210b, which is close to the motor 22, is connected with the motor 22 to be driven to rotate by the motor 22, and then the two axial ends of the second wind wheel 210b are respectively supported by the motor 22 and the base 1, so that the coaxiality of the second wind wheel 210b in the rotating process is ensured, the shaking of the second wind wheel 210b in the rotating process is further reduced, the rotation stability of the second wind wheel 210b is ensured, the second wind wheel 210b is further ensured to have good dynamic balance, the stress of the driving shaft 220 is reduced, and the use reliability of the motor 22 is improved.
Wherein, the bearing seat 31 is detachably connected with the base 1 or is an integral piece; when the bearing seat 31 is detachably connected with the base 1, the bearing seat 31 and the base 1 are respectively two independent components which are connected together by an assembling means, and at the moment, the bearing seat 31 and the base 1 can be detachably connected, so that the air conditioner 100 has good assembly and disassembly flexibility, is convenient for later maintenance, and simultaneously simplifies the structures of the bearing seat 31 and the base 1; when the bearing seat 31 and the base 1 are an integral piece, it is described that the bearing seat 31 and the base 1 are an integral piece and cannot be detached, for example, the bearing seat 31 may be integrally formed with the base 1, or welded to each other, or injection molded twice, so as to ensure the connection reliability between the bearing seat 31 and the base 1. Therefore, the connection mode between the bearing housing 31 and the base 1 has good design flexibility, so that the air conditioner 100 has good structural design flexibility.
It is understood that when the bearing housing 31 is detachably connected to the housing 1, the detachable connection manner between the bearing housing 31 and the housing 1 is not limited, for example, the bearing housing 31 may be connected to the housing 1 by a screw connector (screw or bolt, etc.), a snap, etc.
According to the embodiment of the utility model, the air conditioner 100 is respectively connected with the two wind wheels 21 by arranging the motor 22, so that the two wind wheels 21 can share one motor 22, the number of parts of the air conditioner 100 is reduced, the cost is reduced, meanwhile, the lengths of the two wind wheels 21 can be designed to be shorter, the shaking of each wind wheel 21 during rotation is reduced, each wind wheel 21 has good dynamic balance and operational reliability, the utilization rate of the work of the motor 22 is improved, and the work capacity of the motor 22 is improved; moreover, since the motor 22 is disposed between the two wind wheels 21, the space between the two wind wheels 21 is effectively utilized, so that the structural layout of the air conditioner 100 is compact. Because the two ends of each wind wheel 21 are respectively supported by the motor 22 and the base 1, the swinging of each wind wheel 21 during rotation is further reduced on the premise of ensuring the normal operation of the fan component 2, and the dynamic balance of the wind wheels 21 is further improved. Meanwhile, through the cooperation between the two wind wheels 21, the air conditioner 100 can have multiple air supply modes, so that the use requirements of users can be better met, and the experience effect of the air conditioner 100 is improved. In addition, the bearing housing 31 is detachably coupled to or integrated with the housing 1, which can improve the design flexibility of the air conditioner 100.
Optionally, the first wind wheel 210a is a centrifugal wind wheel or a cross-flow wind wheel, and the second wind wheel 210b is a centrifugal wind wheel or a cross-flow wind wheel, so that the selection of the types of the first wind wheel 210a and the second wind wheel 210b has certain flexibility, and the design flexibility of the air conditioner 100 is ensured. For example, the first wind wheel 210a is a centrifugal wind wheel, the second wind wheel 210b is a centrifugal wind wheel, and the air conditioner 100 has a double centrifugal wind wheel at this time, or the first wind wheel 210a is a cross-flow wind wheel, and the second wind wheel 210b is a cross-flow wind wheel, and the air conditioner 100 has a double cross-flow wind wheel at this time, or one of the first wind wheel 210a and the second wind wheel 210b is a centrifugal wind wheel, and the other is a cross-flow wind wheel.
It will be appreciated that the first and second wind wheels 210a, 210b may also be other types of wind wheels 21, such as axial flow wind wheels, etc. For example, first wind rotor 210a may be a cross-flow wind rotor and second wind rotor 210b may be an axial-flow wind rotor, but is not limited thereto.
For example, in the examples of fig. 8, 10, 12, 16 and 20, the two wind wheels 21 are coaxially disposed, the axis of the first wind wheel 210a coincides with the axis of the second wind wheel 210b, and if the two driving shafts 220 of the motor 22 directly drive the first wind wheel 210a and the second wind wheel 210b to rotate correspondingly, the two driving shafts 220 may be coaxially disposed, which facilitates the arrangement of the motor 22; for another example, the axis of the first wind rotor 210a is parallel to the axis of the second wind rotor 210b, and if the two driving shafts 220 of the motor 22 directly drive the first wind rotor 210a and the second wind rotor 210b to rotate correspondingly, the axes of the two driving shafts 220 may be parallel to each other. Thus, the first wind wheel 210a and the second wind wheel 210b have certain arrangement flexibility, further ensuring design flexibility of the air conditioner 100.
Of course, the axis of the first wind wheel 210a and the axis of the second wind wheel 210b may also intersect or be arranged heteroplanarly. It is understood that when the first wind wheel 210a and the second wind wheel 210b are coaxially disposed, the motor 22 may include one stator and one rotor, thereby simplifying the structure of the motor 22 and reducing the cost, and of course, the motor 22 may include two stators and two rotors to achieve independent control of the two driving shafts 220.
