A mounting hole 225 is formed at a side of the first outlet chamber 230 facing the front of the indoor unit 10 to facilitate the assembly and disassembly of the purification module 224. After the purification module 224 is used for a period of time, the purification module 224 can be disassembled to clean or replace the purification device of the purification module 224, thereby ensuring the quality of air purification. The recess that has is opened to fan module 220's air outlet 223 inboard, can make the convenient dismantlement and the installation of purification module 224, and the user oneself can realize the dismouting, does not need professional's operation, makes this purifier's prevalence higher.
In some alternative embodiments, the fresh air device 200 is disposed at an end portion of one side of the exterior of the casing 100, and is separately and independently installed from the casing 100 of the indoor unit 10, and by using the fresh air device 200 which is independently installed, the existing indoor unit 10 of the air conditioner in a family can be directly installed with the fresh air device 200 on the exterior without being modified or replaced, so that the effect of indoor fresh air exchange can be achieved. By adopting the structure, the installation flexibility of the fresh air device 200 can be realized, the original indoor unit model is not limited, and the maintenance and the repair of the fresh air device 200 are convenient.
In other preferred embodiments, PTC heaters may be disposed between the purification module 224 and the first, second, and third outlet openings 231, 241, and 242 to heat air delivered to the room. When the air conditioner heats, the PTC heater is adopted to preheat air conveyed to the indoor, so that the heat exchange quantity of the heat exchanger 300 of the indoor unit 10 to outdoor air can be further reduced, the heat exchange efficiency of the heat exchanger 300 of the indoor unit 10 to indoor air can be increased, the time for the indoor unit 10 to reach the preset heating temperature is shorter, and the temperature is more stable.
The fresh air device 200 of the present invention may be installed inside the indoor unit 10, integrated with the indoor unit 10, or installed outside the indoor unit 10. No matter the installation state of any form, all can reduce the cost of using the new fan among the prior art by a wide margin, and the noise is low, has better user experience.
In other alternative embodiments, the pipe connection portion 212 is disposed at the lower rear portion of the air intake module 210, and the fresh air intake pipe extends out of the casing 100 along the rear side of the bottom of the casing 100 together with the pipe line of the indoor unit 10, and the fresh air intake further passes through the wall to be introduced outdoors, so that the fresh air outside enters the room through the fresh air intake pipe.
Of course, in some embodiments, depending on the configuration of the indoor unit 10, the duct connection 212 may not be provided, for example, the fresh air inlet duct is directly connected to the rear portion of the air inlet module 210, so as to simplify the structure of the fresh air device 200.
In other preferred embodiments, the rotational axis of the centrifugal fan 221 is parallel to the rotational axis of the supply fan. The arrangement can reduce the noise of the centrifugal fan 221, improve the working efficiency of the centrifugal fan 221 and lead more outdoor fresh air into the room.
The fresh air device 200 in each of the above embodiments can be operated independently of the heating or cooling operation of the indoor unit 10, and can also be operated synchronously with the heating and cooling operation of the indoor unit 10.
