That is, the drain pipe 400 is connected to the water supply source, and the water flows to the filtering device 100, so that the clean water filtered by the filtering device 100 is collected and reused. The clean water filtered by the filtering device 100 is guided to the condenser 300 by the guide structure 500, so that the condenser 300 can radiate heat by using the clean water, and scale is prevented from being deposited on the condenser 300 when the water source directly radiates heat, thereby ensuring the heat exchange effect of the condenser 300.

According to the outdoor unit 1000 of the present invention, the water source is filtered by the filtering device 100 and then dissipates heat to the condenser 300, so that the condenser 300 is prevented from accumulating much water stain dirt, and the heat exchange efficiency of the condenser 300 is improved. In addition, the filtering device 100 is used for filtering the water source, so that on one hand, the structure is simple, the production cost is low, and on the other hand, the maintenance cost of the filtering device 100 is low, and the filtering mode is high in sustainability.

In some embodiments, wherein the filtering apparatus 100 comprises: the water receiving box 110, the first drum 120, the second drum 130, the filter belt 140, and the driving member.

As shown in fig. 4 to 6, the water receiving box 110 is provided with a cleaning water passage 102 and a sewage passage 103, the first drum 120 and the second drum 130 are spaced apart from each other, the filter belt 140 is of a loop structure, and the filter belt 140 is tensioned between the first drum 120 and the second drum 130, and the filter belt 140 may move with the rotation of the first drum 120 or the second drum 130.

The driving member is used for driving at least one of the first roller 120 and the second roller 130 to rotate, and the driving member can drive the filter belt 140 to move, and the driving member drives the upper layer portion of the filter belt 140 to move along the direction from the first roller 120 to the second roller 130. Here, the driving member may drive only the first roller 120 or the second roller 130 to rotate, or the driving member may drive both the first roller 120 and the second roller 130. Alternatively, the driving member may be a motor 150, where the motor 150 is connected to the first roller 120 or the second roller 130, and the motor 150 may drive the first roller 120 or the second roller 130 to rotate so as to move the filter belt 140.

Here, the filter belt 140 may be selected in various types, and may be selected as desired. The different filtering belts 140 are selected, and thus different filtering degrees are selected, so that the cleaning water mentioned in the embodiment of the invention is only the generic term for the liquid of the water source passing through the filtering belts 140, and the sewage is only the generic term for the part of the water source which cannot be filtered.

For example, the filter belt 140 may be a filter screen having a filter hole of 5 μm to 35 μm, filtering the cleaning water through the filter screen, and flowing the cleaning water into the cleaning water passage 102, and the filter screen may leave larger foreign matters on an upper side of the filter screen.
