[0005] Preferably, the dust cover comprises a U-shaped connecting plate and an inclined cover plate, three edges of the U-shaped connecting plate are connected to the inclined cover plate, and screw holes are formed in the U-shaped connecting plate.
[0006] Preferably, a gap is reserved between the inclined cover plate and the water pan.
[0007] Preferably, the waterproof cover comprises an upper cover plate, a front edge plate, and side fixing plates, the front edge of the upper cover plate is connected with the front edge plate, and the front edge plate is perpendicular to the upper cover plate, the side fixing plates are two and are connected with the upper cover plate on the two sides of the front edge plate, and screw holes are formed in the side fixing plates.
[0008] Preferably, the side fixing plates are L-shaped structures.
[0009] Preferably, the protective cover is a "j" shaped structure and is provided with screw holes connected with the heat exchange pipe plate.
[0010] Compared with the prior art, the fan coil casing has the advantages that:
[0011] The fan coil casing has the advantages that: the anti-leakage and dustproof structure is simple, convenient to install, and very practical, compared with the structure in which the whole casing is wrapped around the pipeline and the water pan, the cost is low, the cost is low, the product is more competitive, the problem of copper pipe corrosion and damage and dust accumulation after long-time use of the fan coil product is solved, the number of customer maintenance and maintenance is effectively reduced, and the after-sales maintenance cost is reduced; after wrapping the copper pipe of the heat exchanger, the function of preventing collision, extrusion and card pipe is also achieved during transportation of the machine.
