The indoor unit in the above embodiment may also be used in the technical field of air conditioner equipment, and according to another aspect of the present invention, an air conditioner is provided, which includes an indoor unit, and the indoor unit is the indoor unit in the above embodiment.

Specifically, the air conditioner with the structure solves the problem that the fan blades of the wall-mounted air conditioner are difficult to disassemble, and achieves the functions of easy disassembly and washing and deep cleaning of the air conditioner. Due to the adoption of the fan blade shaft sleeve structure, the problem that the fan blade is difficult to disassemble and install is solved, the fan blade and the air duct can be further deeply cleaned by the wall-mounted air conditioner, and in addition, the disassembling method does not relate to live-line operation and is safe to disassemble.

Traditional wall-hanging air conditioner receives product inner structure and mounting height restriction, and inconvenient cleanness, the user washs traditional air conditioner and generally can only wash outside filter screen, aviation baffle, and extremely difficult washing such as inside wind channel, fan blade, evaporimeter, even wash by the professional, the flow operation is complicated, also can't be with the air conditioner rinse thoroughly.

Adopt the fan blade axle sleeve structure of this application, realize that the through-flow fan blade is light to be dismantled, the installation, and then realize the purpose of clean wind channel of user's degree of depth, fan blade, adopt this kind of dismantlement mode simultaneously, avoid taking motor to dismantle safe and reliable.

Wall-mounted air conditioning ducts are typically airflow channels formed by a bottom housing member, an evaporator 60, surrounding a cross-flow fan. If the traditional air conditioner needs to realize deep cleaning of an air duct, the traditional air conditioner can be realized only by disassembling evaporator parts, but the evaporator parts are connected with refrigerant pipes, and the disassembly and the assembly are completed only by needing complicated operation of professionals. This application divides traditional drain pan part design into two parts: an upper bottom shell component and a lower bottom shell component. Fan blade axle sleeve subassembly. The novel design can rotate and translate, and translation and disassembly of the cross-flow fan blade are achieved. The disassembly of the cross-flow fan blade represents that the inside of an air duct of the air conditioner can be cleaned. The cross-flow fan blade is fixed as shown in an exploded view in fig. 2, the left end of the cross-flow fan blade is connected with a shaft sleeve assembly in a shaft sleeve mode, the right end of the cross-flow fan blade is connected with a motor through a shaft sleeve and a screw, the shaft sleeve assembly is fixed by an upper bottom shell, an evaporator and an angle frame through screws in the vertical direction, and the motor is fixed by the upper bottom shell and a motor pressing plate through screws in the vertical direction.

When the air conditioner needs to be cleaned, the bottom shell is detached, the upper bottom shell part is kept in the mounting structure of the traditional bottom shell part and is fixed on the wall with the evaporator part in a static state, the lower bottom shell part rotates 90 degrees along the rotating shaft of the upper bottom shell, and the air duct is opened. The method for disassembling the cross-flow fan blade comprises the following steps:

the first step is as follows: the bearing rubber ring seat fastener is broken off by hand, and the shaft sleeve assembly is rotated, so that the bearing rubber ring seat clamping boss is separated from the angle-shaped frame clamping groove.

The second step is that: the shaft sleeve assembly is translated along the axial direction of the fan blade, and the bearing rubber ring seat is translated to the limiting rib from the rib on the inner wall of the air duct. Wherein, bearing rubber ring seat translation extreme position reachs spacing muscle, forms the water course between spacing muscle and the drain pan outer wall, blocks the comdenstion water through spacing muscle, avoids the comdenstion water to get into the wind channel.

The third step: and loosening the screws for fixing the motor at the right end of the fan blade.

The fourth step: and translating the cross-flow fan blade to an extreme position along the axial direction towards the shaft sleeve assembly, rotating the fan blade, and taking out the cross-flow fan blade. After the cross-flow fan blade is taken down without a motor, the cleaning of the cross-flow fan blade, the air duct on the inner wall of the bottom shell and the inner surface of the evaporator can be realized.

Before the cross-flow fan blade 20 is translated to the limit position along the axial direction toward the shaft sleeve assembly, one end of the lower bottom shell 12 is operated, so that the other end of the lower bottom shell 12 rotates to the avoidance position around the hinge point of the lower bottom shell 12 and the upper shell 11.
