In some embodiments, as shown in fig. 2 to 4, the structure of the air cleaning apparatus 100 further includes a dehumidifying unit. The dehumidification unit is disposed within the supply air duct 116, and in the supply air duct 116, the blower 110 is located between the supply air port 104 and the dehumidification unit.

Specifically, the dehumidification unit includes a compressor 111, a heat exchanger 112, and a throttling element. Wherein, compressor 111, condenser, throttling element and evaporimeter pass through the pipeline in proper order and carry out closed loop connection, and the throttling element can be the capillary. In the air supply passage 116, the condenser is located at the evaporator and the fan 110, so that the air entering the air supply passage 116 is cooled and dehumidified by the evaporator, and then is heated by the condenser.

It is understood that the dehumidifying unit can dehumidify the air to be flowed into the room to reduce the humidity of the air in the indoor space when the air inner circulation or the air outer circulation is performed. Compared with the air blowing mode to the dehumidification unit, the fan 110 is arranged between the dehumidification unit and the air supply outlet 104, so that the air flowing through the dehumidification unit is in a negative pressure environment manufactured by the fan 110, the air more uniformly passes through the dehumidification unit, the heat exchange area of the air and the dehumidification unit is increased, the dehumidification effect is improved, meanwhile, the wind resistance of the air passing through the dehumidification unit can be reduced, the air outlet area is increased, and the air quantity attenuation is smaller.

In some embodiments, as shown in fig. 2 and 4, in case the air cleaning device 100 has a cleaning and dehumidifying function, the structure of the air cleaning device 100 further includes a heating unit and a second perfuming unit 109.

The heating unit is disposed in the air supply duct 116, and the heating unit is located between the dehumidifying unit and the air supply opening 104. Then, the air to be flowed into the room may be heat-treated by the heating unit, thereby increasing the temperature of the air in the room and realizing the warm air function of the air cleaning apparatus 100. It is understood that the heating unit may be a PTC (Positive Temperature Coefficient, i.e., positive temperature coefficient) heater.

In addition, after the humidification of the air is completed, the heating function of the air purifying device 100 can be started, so that the heated air can dry the wet film unit 303, and the problems that the wet film unit 303 remains moisture and bacteria grow are prevented.

The second perfuming unit 109 is disposed in the return air duct 114, and the second perfuming unit 109 has a perfuming outlet, which communicates with the air supply duct 116. Then, the air flowing into the room may be subjected to a perfuming process using the second perfuming unit 109, thereby increasing the fragrance of the air in the room. It will be appreciated that the second perfuming unit 109 comprises a fragrance generator and a fragrance bottle. The second perfuming unit 109 is disposed in the return air channel 114, so that the space of the return air channel 114 can be utilized to avoid excessive parts disposed in the air supply channel 116.

Of course, it is not excluded that the air cleaning device 100 of the above-described structure is provided with only the heating unit or the second perfuming unit 109.
