In the embodiment, the second fan 2 drives the first fan 13 to rotate, so that the second fan 2 and the first fan 13 share the same motor, and compared with the single use of two motors, the transverse size of the indoor air conditioner is reduced; meanwhile, the cost of the product can be reduced by using one motor, and the electric quantity consumption of the air conditioner during operation is reduced.

Specifically, since the air conditioner shown in this embodiment includes the fresh air module 1 shown in the above embodiment, the air conditioner shown in this embodiment includes all the technical solutions of the above embodiment, and therefore, at least all the beneficial effects obtained by all the technical solutions of the above embodiment are obtained, and details are not repeated here.

In some embodiments, as shown in fig. 1-3, the air conditioner further comprises a cabinet 7; the fresh air module 1 is arranged outside the machine shell 7, and the air outlet 112 is arranged on one side surface of the shell body 11 deviating from the machine shell 7.

In this embodiment, the air outlet 112 of the fresh air module 1 is arranged on one side of the casing 7, and sends out the fresh air in the direction perpendicular to the air outlet direction of the air conditioner, so that the fresh air is blown to the indoor direction to avoid the human body, and the comfort level of the air outlet of the fresh air module 1 is increased.

In some embodiments, as shown in fig. 3, the distance between the center of the air inlet 111 of the fresh air module 1 and the horizontal ground is greater than the distance between the center of the air outlet 112 of the fresh air module 1 and the horizontal ground, and the change of the relative positions of the air inlet 111 and the air outlet 112 of the fresh air module 1 can make the fresh air enter from the upper side and blow out from the lower side of the fresh air module 1, so as to prevent the dust in the fresh air from accumulating in the housing 11 of the fresh air module 1.

Here, the air conditioner that this embodiment provided is through installing above-mentioned new trend module 1 to install new trend module 1 in one side of casing 7, can make the new trend blow to indoor direction and avoid the human body, increase the comfort level of the air-out of new trend module 1, the change of the relative position of air intake 111 and air outlet 112 of new trend module 1 simultaneously can effectively prevent the accumulation of the dust in the new trend in the casing 11 of new trend module 1.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
