[0002] The fan coil unit is a common air conditioning terminal device, which is widely used in commercial buildings, office buildings, hotels, hospitals and other places. It uses the internal fan to blow air through the cooling or heating coil to adjust the indoor air temperature and humidity. During use, the air outlet of the fan coil unit will accumulate a lot of dust due to long-term accumulation, and the heat exchange plate used to improve the heat exchange needs to be regularly inspected and cleaned. This requires the outer shell of the fan coil unit to be disassembled, and the air outlet components such as the dust plate and the internal heat exchange plate to be inspected and used accordingly. Most of the common fan coil units have their outer shells connected by multiple sets of screws to complete the disassembly and assembly, and most of the fan coil units are installed at high places and have a concealed structure, which requires operators to perform high-altitude operations, and the screw structure will rust after long-term use, making the fixing method of the screw connection structure inconvenient to disassemble and assemble, which in turn makes the fan coil unit inconvenient to inspect and repair.
