In an embodiment of the present invention, as shown in fig. 1 to 4, the air conditioner 100 includes a housing 10 and a fan assembly 20.

The housing 10 has an air inlet 11, an air outlet, and a heat exchange air duct 13 communicating the air inlet 11 and the air outlet. Indoor air enters the heat exchange air duct 13 from the air inlet 11, exchanges heat in the heat exchange air duct 13 and then is sent into a room through the air outlet. Optionally, the housing 10 includes a front housing 14 and a rear housing 15 cooperatively connected with the front housing 14, the air inlet 11 is disposed on the rear housing 15, and the air outlet is disposed on the front housing 14.

In the present embodiment, as shown in fig. 1 to 4, the heat exchanger 30 is disposed at the air inlet 11, and the fan assembly 20 is disposed at the air outlet side of the heat exchanger 30.

Further, as shown in fig. 5-21, and with particular reference to fig. 5, 6, and 19-21, the fan assembly 20 includes a wind wheel 21, a first motor 22, a second motor 23, and a transmission. The first motor 22 is rotatably disposed in the heat exchange air duct 13, the first motor 22 has a first driving shaft 221, and the wind wheel 21 is disposed on the first driving shaft 221. Second motor 23 is fixed in heat transfer wind channel 13, just second motor 23 and first motor 22 are the interval setting, second motor 23 has second drive shaft 231, the axis of second drive shaft 231 is the contained angle setting with the axis of first drive shaft 221, second drive shaft 231 passes through the driving medium and is connected with first motor 22. The second motor 23 is used to drive the first motor 22 to rotate through a transmission member, so as to rotate the first driving shaft 221 around the second driving shaft 231.

As shown in fig. 19 and 21, when the air conditioner 100 is operated, the first motor 22 drives the wind wheel 21 (to rotate (i.e., to rotate) about (the axis of) the first drive shaft 221, i.e., the rotation axis of the wind wheel 21 itself) by the first drive shaft 221; meanwhile, the second motor 23 drives the first motor 22 to rotate through a transmission piece, and because the axis of the second driving shaft 231 and the axis of the first driving shaft 221 form an included angle, the axis of the first driving shaft 221 can rotate around the axis of the second driving shaft 231, and then the wind wheel 21 can be driven to rotate around the axis of the second driving shaft 231. Therefore, when the air conditioner 100 works, the wind wheel 21 can rotate around the rotation axis of the wind wheel, and the wind wheel 21 can rotate around the axis of the second driving shaft 231 (so that the wind wheel 21 supplies air to form a spiral type, the air supply range can be expanded, the air supply speed and the air supply distance are increased, and the comfort level of a user is met.

It can be understood that the axis of the first driving shaft 221 rotates around the axis of the second driving shaft 231 to form a rotation track, and the rotation track is a conical surface or a circular table surface.

Specifically, as shown in fig. 5, 6, and 19-21, the second motor 23 and the first motor 22 are disposed at an interval in the air outlet direction of the heat exchange air duct 13, the first driving shaft 221 is disposed at one end of the first motor 22 far from the second motor 23, and both the second driving shaft 231 and one end of the first motor 22 close to the second motor 23 are connected to a transmission member, so that the second motor 23 drives the first rotation.

In particular, said transmission is an eccentric transmission, so that the second motor 23 drives the (axis of the) first drive shaft 221 to rotate around the (axis of the) second drive shaft 231.

That is, in this embodiment, as shown in fig. 5, 6, and 19-21, the second motor 23 and the first motor 22 are disposed at an interval in the air outlet direction of the heat exchange air duct 13, one end of the first motor 22 away from the second motor 23 is provided with a first driving shaft 221, and the wind wheel 21 is disposed on the first driving shaft 221; the second motor 23 has a second driving shaft 231, and the ends of the second driving shaft 231 and the first motor 22 close to the second motor 23 are both connected to an eccentric transmission member, and the axis of the second driving shaft 231 and the axis of the first driving shaft 221 are arranged at an included angle.

Thus, when the air conditioner 100 operates, the first motor 22 drives the wind wheel 21 to rotate around the rotation axis thereof through the first driving shaft 221; meanwhile, the second motor 23 drives the first motor 22 to rotate through an eccentric transmission member, and because the axis of the second driving shaft 231 and the axis of the first driving shaft 221 form an included angle, the first driving shaft 221 can rotate around the axis of the second driving shaft 231 (so as to drive the wind wheel 21 to rotate around the axis of the second driving shaft 231). Therefore, when the air conditioner 100 works, the wind wheel 21 can rotate around the rotation axis of the wind wheel, and the wind wheel 21 can rotate around the axis of the second driving shaft 231 (so that the wind wheel 21 supplies air to form a spiral type, the air supply range of the wind wheel 21 and the air conditioner 100 can be enlarged, the air supply speed and the air supply distance are increased, and the comfort level of a user is met.

It should be noted that, in the embodiment, a support structure may be directly formed in the heat exchanging air duct 13 for supporting the first electrode to rotate and for fixing the second electrode; the fan assembly 20 may also be provided with its own support features to enhance the independence of the fan assembly 20 to facilitate installation of the fan assembly 20. In the following description of the present invention, the fan assembly 20 itself has a support member as an example.

Further, as shown in fig. 5, 6, and 19-21, the fan assembly 20 further includes a mounting base 25 fixed in the heat exchange air duct 13, and the first motor 22 is rotatably mounted on the mounting base 25, so that the first motor 22 is rotatably disposed in the heat exchange air duct 13; the second motor 23 is fixedly mounted on the mounting seat 25, so that the second motor 23 is fixed in the heat exchange air duct 13.

Further, as shown in fig. 5, 6, and 19-21, the eccentric transmission member is an eccentric wheel 24, and the eccentric wheel 24 is movably connected with one end of the first motor 22 close to the second motor 23 in a matching manner; the eccentric wheel 24 is provided with an eccentric hole 241, a preset distance is arranged between the center line of the eccentric hole 241 and the center line of the eccentric wheel 24, and the second driving shaft 231 is installed in the eccentric hole 241 to drive the eccentric wheel 24 to rotate, so that the eccentric wheel 24 drives the first motor 22 to rotate, so that (the axis of) the first driving shaft 221 rotates around (the axis of) the second driving shaft 231.

In this way, by providing the eccentric transmission member as the eccentric wheel 24, it is possible to facilitate, on the one hand, the second motor 23 to drive the (axis of the) first driving shaft 221 to rotate about the (axis of the) second driving shaft 231, and, on the other hand, to simplify the structure of the eccentric transmission member, so as to simplify the structure of the connection between the eccentric transmission member and the first motor 22.

Further, as shown in fig. 5, 6, and 19-21, the fan assembly 20 further includes a fan housing 26, and the first motor 22 is fixedly mounted within the fan housing 26. Specifically, a fan assembly cavity matched with the shape of the first motor 22 is defined in the fan shell 26, and the first motor 22 is matched and installed in the fan assembly cavity; the fan housing 26 is further provided with a shaft through hole (not shown) communicated with the fan assembly cavity, and the first driving shaft 221 extends out of the fan housing 26 through the shaft through hole.

In this way, forming a mounting structure directly on the first motor 22 or a mating structure with the eccentric wheel 24 and the like can be avoided, thereby simplifying the production process of the first motor 22.

Optionally, the fan housing 26 is further provided with a heat dissipation through hole 2611 communicated with the fan mounting cavity, so as to at least achieve heat dissipation.

In this embodiment, as shown in fig. 7, the fan case 26 includes a case body 261 having an opening at one end, and a cover 262 disposed at the opening of the case body 261, and the shaft passing hole is disposed at the bottom of the case body 261. Optionally, the heat dissipation through hole 2611 is disposed on the shell body 261.

Further, as shown in FIGS. 5, 6, and 19-21, the eccentric 24 is movably coupled to the fan housing 26. Specifically, the eccentric wheel 24 and the fan casing 26 are provided with a movable fit structure, so that the eccentric wheel 24 and the fan casing 26 are movably connected in a fit manner.

Further, as shown in fig. 7, a driving hole 2621 is formed on a side surface of the fan housing 26 facing the second motor 23, and the eccentric wheel 24 is movably disposed in the driving hole 2621 so that a circumferential surface of the eccentric wheel 24 is in rolling contact with a circumferential wall of the driving hole 2621 when the eccentric wheel 24 rotates. Specifically, the eccentric wheel 24 can rotate in the driving hole 2621 and can rotate 360 degrees. In this way, during the rotation of the eccentric wheel 24, the outer peripheral surface of the eccentric wheel 24 can continuously roll and abut against the peripheral wall of the driving hole 2621 to drive the second motor 23 to rotate, so that (the axis of) the first driving shaft 221 rotates around (the axis of) the second driving shaft 231.

Optionally, the driving hole 2621 is a circular hole or a circular-like hole to improve the rotation uniformity of the second motor 23.

Optionally, the diameter of the eccentric 24 is smaller than the diameter of the driving hole 2621. So that the eccentric 24 is in rolling contact with the circumferential wall of the driving hole 2621.

Alternatively, as shown in fig. 14 and 15, the side of the eccentric wheel 24 away from the wind wheel 21 is convexly provided with an eccentric convex part, and the eccentric hole 241 is arranged in the eccentric convex part to enhance the structural strength.

Further, as shown in fig. 7, a plurality of anti-sticking protrusions 2623 are convexly arranged on the inner peripheral wall of the driving hole 2621, and the anti-sticking protrusions 2623 are distributed at intervals along the circumferential direction of the center line of the driving hole 2621. In this way, the rotational resistance between the eccentric wheel 24 and the driving hole 2621 when rotating can be reduced, so that jamming can be prevented.

Specifically, the anti-sticking portion 2623 extends in the extending direction of the center line of the driving hole 2621. Of course, the anti-jamming portion 2623 may be a spherical protrusion or a hemispherical protrusion.

In the present embodiment, as shown in fig. 7, the driving hole 2621 is provided on a side surface of the cover 262 facing the second motor 23. Specifically, a ring plate is convexly disposed on a side surface of the cover 262 facing the second motor 23, and the driving hole 2621 is formed on an inner side of the ring plate.

It can be understood that one or more of the distance between the first motor 22 and the second motor 23, the diameter and depth of the driving hole 2621, and the diameter and thickness of the eccentric wheel 24 may be designed to ensure that not only the eccentric wheel 24 is movably disposed in the driving hole 2621, but also the circumferential surface of the eccentric wheel 24 is continuously in rolling contact with the circumferential wall of the driving hole 2621 when the eccentric wheel 24 rotates; the eccentric 24 is also prevented from coming out of the driving hole 2621.

It should be noted that, in other embodiments, the driving hole 2621 may also be disposed directly on the end surface of the first motor 22 facing the second motor 23.

It should be noted that the eccentric wheel 24 may be movably connected to the end of the first motor 22 close to the second motor 23 by other configurations.

For example, in another embodiment of the present invention, as shown in fig. 27, a driving protrusion 2622 is protruded from a side surface of the fan case 26 facing the second motor 23, the eccentric wheel 24 is further provided with a transmission hole 242 spaced apart from the eccentric hole 241, and the driving protrusion 2622 is movably disposed in the transmission hole 242, so that the circumferential wall of the transmission hole 242 is in rolling contact with the driving protrusion 2622 when the eccentric wheel 24 rotates. Specifically, the driving protrusion 2622 can rotate in the transmission hole 242, and can rotate 360 degrees. In this way, during the rotation of the eccentric wheel 24, the transmission hole 242 rotates around (the axis of) the second driving shaft 231 along with the eccentric wheel 24, and the peripheral wall of the transmission hole 242 can continuously roll and abut against the driving protrusion 2622 to drive the second motor 23 to rotate, so that (the axis of) the first driving shaft 221 rotates around (the axis of) the second driving shaft 231.

In this embodiment, optionally, the center line of the transmission hole 242 is disposed close to the center line of the eccentric 24, or the center line of the transmission hole 242 coincides with the center line of the eccentric 24.

In this embodiment, it is to be noted that, in a modified embodiment of this embodiment, the driving protrusion 2622 may also be directly disposed on an end surface of the first motor 22 facing the second motor 23.

It should be noted that, in other embodiments, the eccentric transmission member may be configured as a crank, a connecting rod assembly, or the like, and the specific connection relationship and structure thereof can be easily obtained according to the disclosure of the present invention, and need not be described in detail herein.

Further, as shown in fig. 19 and 21, an angle R between the axis of the second drive shaft 231 and the axis of the first drive shaft 221 is less than or equal to 30 degrees. It can be understood that if the included angle is too large, the rotation range of the wind wheel 21 around (the axis of) the second driving shaft 231 is too large, and the avoidance design requirement for the rotation of the wind wheel 21 around (the axis of) the second driving shaft 231 is too high, and the structural strength, the quality and the like of the wind wheel 21 and the supporting structure for supporting the rotation of the wind wheel 21 around (the axis of) the second driving shaft 231 are also too high. In this way, the included angle R between the axis of the second driving shaft 231 and the axis of the first driving shaft 221 is less than or equal to 30 degrees, so that the air supply range can be expanded, and the comfort of the user can be satisfied.

Optionally, an angle R between the axis of the second driving shaft 231 and the axis of the first driving shaft 221 is less than or equal to 15 degrees.

Further, as shown in fig. 10 and 22, the fan assembly 20 further includes a spherical joint bearing 27, and the spherical joint bearing 27 is fixed in the heat exchange air duct 13 and sleeved on the first driving shaft 221.

Specifically, as shown in fig. 10 and 22, the spherical joint bearing 27 includes an outer ring 271 and an inner ring 272 rotatably disposed on the outer ring 271, the outer ring 271 is fixed to the mounting seat 25 (so that the spherical joint bearing 27 is fixed in the heat exchange air duct 13), and the first driving shaft 221 is sleeved in the inner ring 272, so that the first motor 22 and the first driving shaft 221 are rotatably mounted on the mounting seat 25. In this manner, the rotation of the first driving shaft 221 relative to the mounting seat 25 about the axis of the first driving shaft 221 can be facilitated, so as to reduce the abrasion of the mounting seat 25 on the first driving shaft 221, and thus improve the reliability of the operation of the first motor 22.

Further, as shown in fig. 16, 21 and 22, the mounting base 25 includes a bottom plate 251, and a first supporting portion 252 and a second supporting portion 253 which are disposed on the bottom plate 251, the bottom plate 251 is fixedly disposed in the heat exchanging air duct 13, the first supporting portion 252 and the second supporting portion 253 are disposed oppositely, the outer ring 271 is mounted on the first supporting portion 252, the motor housing is disposed between the two supporting portions, and the second motor 23 is fixed on the second supporting portion 253.

Specifically, the air conditioner 100 further includes a transverse support 40 disposed in the heat exchange air duct 13, two ends of the transverse support 40 are respectively connected to two side walls of the casing 10, and the bottom plate 251 is mounted on the transverse support 40.
