As shown in fig. 2, fig. 3 and fig. 4, air enters the indoor air duct from the left and right side plate filter screens and from the formaldehyde removing filter screen, wherein the left and right side plate filter screens, the formaldehyde removing filter screens, the upper centrifugal air duct, the centrifugal fan blades and the centrifugal motor form the upper air duct. Wherein the outward appearance shape of filter screen refers to fig. 4, and in order to guarantee pleasing to the eye, the curb plate filter screen herein adopts the metal material, conveniently makes the fretwork effect, simultaneously because the curb plate will be thinner than department's thickness such as drain pan, panel body, adopts the metal material also can effectively guarantee not to warp.

Wherein, the mounted position who removes the formaldehyde filter screen requires to be located the rear of the panel body, the same also need to be located top cambered surface department, it is in order to guarantee the outward appearance to require the mounted position to be located the back of the panel body, the customer sees the complete smooth outward appearance of air conditioner from openly like this, but not directly seeing the filter screen, it is not the plane to require to be located top cambered surface, when avoiding the user to lean on wall installation air conditioner, the air intake is leaned on the wall to be blocked up, unable effective air inlet, consequently, it can be in the wind channel in order to guarantee windy can see through removing the formaldehyde filter screen to require to be located the top.

The formaldehyde removing filter screen is selectively arranged at the joint of the centrifugal fan, so that the air can continuously enter the two sides of the centrifugal fan when entering the air conditioner after passing through the formaldehyde removing filter screen. So, remove formaldehyde filter screen department and can guarantee that 3 centrifugal fan's four sides can both obtain the air inlet, the filter screen of controlling the curb plate then guarantees that remaining two sides can effective air inlet, so, six side air intakes of whole three centrifugal fan can both obtain effective air inlet. Air is sucked from two sides of the centrifugal fan blade, is thrown out in a manner of being vertical to the axial direction of the centrifugal fan blade, and is directly blown into the cavity of the indoor unit after passing through the centrifugal air duct.

In the indoor unit cavity part, the water pan 51 can be fixed on the panel body, also can be fixed on the drain pan, also can regard as independent part, through the fix with screw on the drain pan, in this application, first-selected water pan passes through screw and drain pan connection. The main reason is that in the production and assembly process, a through-flow fan blade needs to be installed and can be conveniently and quickly installed through screw connection. The water pan is mainly used for storing condensed water generated in the heat exchange process of the two devices when the air conditioner is refrigerated, and then the condensed water is discharged through the drain pipe. The cross-flow fan 22 is driven by a motor 53.

After entering the indoor machine cavity, the blowing air penetrates through the heat exchanger 40 and enters the wind field of the lower cross-flow fan blade, wherein the air deflector 52 can be automatically opened upwards when the air conditioner operates, and the smooth air outlet is ensured. Similarly, when the air conditioner stops running, the air deflector is automatically closed. Therefore, air participates in each part of heat exchange of the air conditioner, and the performance of the indoor unit is effectively improved.
