Specifically, a matched gear may be disposed on the rotation shaft 410 and the transmission shaft of the driver 400, and the rotation shaft 410 of the driver 400 drives the transmission shaft to rotate in a gear transmission manner, and of course, a belt pulley may be disposed on the rotation shaft 410 and the transmission shaft of the driver 400, and the rotation shaft 410 of the driver 400 drives the transmission shaft to rotate in a belt transmission manner. It should be understood that, after the different shafts of the fresh air fan 310 and the air conditioner fan 210 are disposed, the specific mounting positions of the fresh air fan 310 and the air conditioner fan 210 can be selected more flexibly, and the purpose of changing the relative positional relationship between the rotating shaft 410 and the driving shaft can be achieved by adjusting the specific structure and the size of the driving mechanism, such as the gear driving mechanism or the belt pulley driving mechanism, between the rotating shaft 410 and the driving shaft, so that the air conditioner fan 210 and the fresh air fan 310 respectively disposed on different shaft portions can be disposed at different positions.

A speed reducing mechanism may be further disposed between the rotating shaft 410 and the driving shaft of the driver 400, so that the rotating shaft 410 and the driving shaft of the driver 400 may rotate at different rotation speeds, the air conditioning fan 210 may be connected to the rotating shaft 410, and the fresh air fan 310 may be connected to the driving shaft, thereby enabling the rotation speed of the fresh air fan 310 to be adjustable. Specifically, when the outdoor temperature is higher, the indoor temperature is also higher, the cooling temperature of the air conditioner can be reduced more quickly, and accordingly, the rotation speed of the air conditioner fan 210 is also relatively faster, and the outdoor higher temperature can cause the fresh air fan 310 to input the air with the higher outdoor temperature into the indoor to affect the indoor cooling rate, so that the rotation speed of the fresh air fan 310 can be reduced to reduce the ventilation efficiency of the indoor air, and thus the indoor temperature reduction efficiency is faster. Therefore, the fresh air fan 310 can be freely adjusted by arranging the speed reducing mechanism so as to adapt to various indoor environments.

In some embodiments, in order to make the structure of the air conditioner indoor unit of the present application more compact, the fresh air module 300 and the driver 400 may be disposed in the casing 100, specifically may be disposed on two opposite sides in the casing 100, after the fresh air module 300 is disposed in the casing 100, when the air conditioner indoor unit of the present application is installed, the casing 100 is fixed on an installation wall surface, and then the purpose of installing the fresh air module 300 in a room can be achieved, so that the fresh air module 300 may not need to be separately installed, and accordingly, an installation structure for installing the fresh air module 300 does not need to be additionally provided, so as to achieve the purpose of simplifying the structure of the air conditioner indoor unit of the present application. In addition, when the fresh air module 300 and the driver 400 are disposed in the housing 100, the housing 100 can also protect the fresh air module 300 and the driver 400.

Specifically, the rotating shaft 410 of the driver 400 may extend along the length direction of the casing 100 to be connected to two fresh air fans 310 passing through the fresh air casing 320 and in the fresh air casing 320, and, of course, in order to avoid the too long length of the rotating shaft 410, a plurality of rotating shafts 410 may be further disposed and connected to the plurality of rotating shafts 410 through a coupling, so that the air conditioning fan 210 and the fresh air fans 310 are coaxially disposed.

In addition, in order to further ensure the reliable fixing and installing effect of the fresh air module 300, the fresh air module 300 may be fixedly connected with the air conditioner module 200, so that the fresh air module 300 and the air conditioner module 200 may be mutually supported and installed, so that the fresh air module 300 may be stably installed in the housing 100.

In some embodiments, it should be understood that during the operation of the air conditioner, the air conditioner module 200 may suck in indoor air through the air inlet 120 of the housing 100, and the air may be discharged through the air outlet 130 of the housing 100 after passing through the heat exchanger of the air conditioner module 200, so as to achieve the purpose of cooling or heating the air. The fresh air outlet 322 of the fresh air shell 320 of the present application may be disposed adjacent to the air conditioning module 200, specifically, the fresh air outlet 322 of the fresh air shell 320 may be disposed on a side of the fresh air shell 320 adjacent to the air conditioning module 200, so that fresh air output by the fresh air outlet 322 of the fresh air shell 320 is closer to the air inlet 120 of the housing 100, so that fresh air output by the fresh air outlet 322 of the fresh air shell 320 is easier to be inhaled into the inner cavity 110 of the housing 100 by the air inlet 120 of the housing 100, so that fresh air output by the fresh air outlet 322 of the fresh air shell 320 may enter the inner cavity 110 of the housing 100 and contact with the heat exchanger in the inner cavity 110 of the housing 100, so that fresh air output by the fresh air outlet 322 of the fresh air shell 320 may be heated or cooled, thereby making the influence of the temperature of the fresh air output by the housing 100 on the indoor temperature relatively small.

Specifically, when the outdoor temperature is higher, and the air conditioner is in the refrigeration mode, the indoor temperature is relatively lower, and when the fresh air module 300 inputs the outdoor air with higher temperature into the indoor, the temperature of the fresh air is higher, and the influence on the indoor temperature can be caused, so that the fresh air can be cooled by the heat exchanger after entering the inner cavity 110 of the shell 100 through the air inlet 120 of the shell 100, and the air conditioner indoor unit can output the fresh air after heating so as to improve the indoor air quality under the condition of changing the indoor temperature.
