According to the air cold and hot circulation principle, the cold air has higher density than the air at normal temperature, and the air outlet should blow upwards during refrigeration, so that the cold air sinks to cool the whole room; the density of the hot air is smaller than that of the air at normal temperature, and the air outlet is suitable for blowing downwards during heating, so that the hot air rises, and the whole room is heated.

Therefore, in this embodiment, in order to make the air conditioner better realize the functions of cooling and heating, the air conditioner main unit 4 is provided with a first air outlet and a second air outlet, where the first air outlet is used for guiding the air flow to be led out along the first direction; the second air outlet is used for guiding the air flow to be guided out along a second direction; the first direction and the second direction are disposed at an included angle, specifically, in this embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction.

In this embodiment, specifically, the first air deflector 1 and the second air deflector 2 may achieve four states.

Initial state: the first air deflector 1 and the second air deflector 2 are both positioned at the positions of being sealed at two air outlets.

First use state: when horizontal air outlet is performed, at this time, the first air deflector 1 needs to be opened relative to the air outlet, and the second air deflector 2 is closed, that is, kept in a non-rotating state.

In this use state, from the initial state, the second gear teeth 34 start to rotate, and at this time, the third gear section 341 of the second gear teeth 34 starts to be meshed with the second gear section 332 of the first gear teeth 33, so that the second gear teeth 34 rotate to drive the first gear teeth 33 to rotate, and because the first gear section 331 is meshed with the first output gear teeth 31, the first gear teeth 33 rotate to drive the first output gear teeth 31 to rotate, so that the first air deflector 1 rotates; the fourth transmission section 342 of the second transmission gear 34 is in rolling connection with the missing gear of the second output gear 32, and at this time, the rotation of the second transmission gear 34 does not drive the second output gear 32 to rotate, so that the second air deflector 2 does not rotate, that is, in this state, the first air deflector 1 rotates, and the second air deflector 2 does not rotate.

Second use state: in the case of angular air-out, the first air guide plate 1 and the second air guide plate 2 need to rotate simultaneously.

In this use state, from the first use state, the second gear teeth 34 continue to rotate, and after the second gear teeth 34 rotate to the first position, the fourth gear section 342 of the second gear teeth 34 also starts to be engaged with the second output gear teeth 32, and at this time, the second gear teeth 34 are engaged with the first gear teeth 33 and also engaged with the second output gear teeth 32, and when the second gear teeth 34 continue to rotate, the first gear teeth 33 and the second output gear teeth 32 rotate simultaneously, so that the first output gear teeth 31 also rotate therewith, and therefore, in this state, the first air deflector 1 and the second air deflector 2 rotate simultaneously.

Third use state: in the case of vertical air-out, the first air guide plate 1 and the second air guide plate 2 need to be rotated to the vertical position at the same time.

In this use state, from the second use state, the second driving gear 34 continues to rotate and drives the first driving gear 33 and the second output gear 32 to rotate, and the first output gear 31 also rotates along with the second driving gear, so that the first air deflector 1 and the second air deflector 2 simultaneously rotate to the vertical position, and the first air outlet is closed, so that the air conditioning air is led out from the second air outlet.

The first air deflector 1 can be regarded as the extension board of second air deflector 2, has equivalent to the length that has prolonged horizontal air-out passageway, to the indoor set of air conditioner, longer horizontal air-out passageway can make the air conditioner wind blow more far away, covers bigger indoor space to make indoor environment temperature change more obvious, effectively promoted the air conditioner and adjusted indoor temperature's efficiency, improved user's use experience.

It should be noted that, the first air deflector 1 and the second air deflector 2 are not necessarily perpendicular to each other, and the central angles of the first tooth-missing section 343 and the second tooth-missing section 381 are not necessarily set to 90 °, that is, the first air deflector 1 and the second air deflector 2 do not necessarily form a plane in the third use state. The central angle of the first tooth-missing section 343 can be set to other degrees, so that an included angle can be formed between the first air deflector 1 and the second air deflector 2 in the third use state, and at the moment, the first air deflector 1 or the second air deflector 2 can play a role of a wind deflector, thereby blocking air-conditioning wind from directly blowing to a human body and achieving a better air supply effect. The angle of the central angle of the first tooth-missing section 343 may be set according to the actual situation.

Of course, under other conditions, the variable-shaft driven double air deflector can be applied to a fan, so long as two-direction air outlet needs to be achieved, or other air outlet devices in the prior art can also apply the double air deflector, and the double air deflector can be applied and arranged according to actual conditions.

Further, a first meshing tooth segment and a first tooth missing segment 343 are arranged in the rotation direction of the fourth transmission segment 342; the first tooth segment 343 is in rolling engagement with the second output tooth 32 and the first tooth segment is in meshing engagement with the second output tooth 32.

On the basis of the above structure, the second gear teeth 34 include a third gear section 341 and a fourth gear section 342, the third gear section 341 is a meshing gear section, the fourth gear section 342 is provided with first meshing gear sections 343 and first missing gear sections 343 distributed in the rotation direction of the fourth gear section 342, the meshing gear sections of the third gear section 341 are always meshed with the first gear teeth 33, the first missing gear sections 343 on the fourth gear section 342 are in rolling connection with the second output gear 32, and the first meshing gear sections are meshed with the second output gear 32.

In the initial state and the first use state, the first tooth missing section 343 on the fourth transmission section 342 is in tooth missing rolling connection with the second output tooth 32, so that in the first use state, the second transmission tooth 34 rotates, the second output tooth 32 cannot rotate along with the first transmission tooth, the first transmission tooth 33 rotates and drives the first output tooth 31 to rotate, namely the first air deflector 1 rotates, and the second air deflector 2 does not rotate.

In the second use state and the third use state, the first meshing tooth section on the fourth transmission section 342 is meshed with the second output tooth 32, and in the two use states, the second transmission tooth 34 rotates, and the first transmission tooth 33 and the second output tooth 32 also rotate along with the rotation of the second transmission tooth section, and drive the first output tooth 31 to rotate, that is, the first air deflector 1 and the second air deflector 2 rotate simultaneously.

By providing the third transmission section 341 and the fourth transmission section 342 on the left and right sides of the second transmission gear 34 in the axial direction, respectively, the first transmission gear 33 and the second output gear 32 on the second rotation shaft 302 are respectively corresponding, so that the first air deflector 1 and the second air deflector 2 are switched between the first use state, the second use state and the third use state.

Compared with the prior art, the air conditioner has the advantages that the first air guide plate 1 and the second air guide plate 2 are driven by the two driving mechanisms respectively, so that the rotation of the first air guide plate 1 and the second air guide plate 2 can be realized, the first air guide plate 1 and the second air guide plate 2 can be converted among the first using state, the second using state and the third using state by only one driving mechanism, the air conditioner is more convenient and the cost is reduced, the occupied space of the driving assembly 30 in the air conditioner host 4 can be effectively reduced, the volume of the air conditioner host 4 can be effectively reduced, and the air conditioner is more concise and attractive.

The assembly mode can also realize the conversion between the first air deflector 1 and the second air deflector 2 in the first use state, the second use state and the third use state, but because the rotation axes of the first air deflector 1 and the second air deflector 2 are different, the first air deflector 1 and the second air deflector 2 can move up and down relatively in the rotation process, so that an assembly gap is formed during rotation, air leakage can be possibly generated, energy loss is caused, and the working efficiency of the air conditioner is reduced. Of course, the selection and setting can be made according to the actual situation.

In addition, in the present embodiment, the third transmission section 341 and the fourth transmission section 342 of the second gear 34 are integrally formed, and of course, the third transmission section 341 and the fourth transmission section 342 may also be fastened and connected by using fasteners, such as bolts, welding or bonding, and may be selected and set according to the actual situation.

Further, as shown in fig. 3, the fourth transmission section 342 is provided with an arc guiding surface, which extends along the circumferential direction of the fourth transmission section 342 and forms a first tooth-missing section 343.

On the basis of the above structure, an arc guide surface is provided on the fourth transmission section 342, and the arc guide surface forms the first tooth missing section 343.

In the first use state, when the second transmission gear 34 rotates, the second output gear 32 slides on the circular arc guide surface, that is, the second transmission gear 34 is not rotated to drive the second output gear 32 to rotate at this time, and because the second output gear 32 is attached to the circular arc guide surface, the second output gear 32 is prevented from rotating under the action of the weight of the second air deflector 2 or the external factors, so that the second air deflector 2 is prevented from rotating in the first use state.

In the second and third use states, the second output teeth 32 are already engaged with the fourth transmission section 342 of the second transmission teeth 34 when the second transmission teeth 34 are rotated, and the second output teeth 32 are rotated together when the second transmission teeth 34 are rotated, so that the second wind deflector 2 is also rotated.

Further, the first meshing tooth sections of the circular arc guide surface on both sides of the rotation direction form limit teeth, the second output tooth 32 is provided with positioning teeth, the positioning teeth are provided with tooth tops attached to the circular arc guide surface, and the positioning teeth are in butt fit with the limit teeth.

On the basis of the above structure, in the initial state, when the tooth tops of the positioning teeth on the second output teeth 32 are attached to the circular arc guide surface, the positioning teeth can not rotate along with the rotation of the circular arc guide surface during the rotation of the second transmission teeth 34, and the positioning teeth are in abutting fit with the limiting teeth to prevent the second output teeth 32 from rotating due to the gravity of the second air deflector 2 in order to realize stable assembly after assembly or in the initial state.
