[0002] The air conditioner is divided into an indoor unit and an outdoor unit. The outdoor unit of the air conditioner is an important component in the air conditioning system. Its main function is to discharge the indoor heat to the outside through the refrigeration cycle to regulate the indoor temperature. A large amount of heat will be generated when the air conditioner is used indoors. The outdoor unit of the air conditioner absorbs the indoor heat into the outdoor unit through the refrigeration cycle system, and then transfers the heat to the surrounding air through the heat sink on the outdoor unit. This can ensure that the indoor temperature drops and make people feel cool and comfortable.

[0003] The interior of the air conditioner mainly includes an evaporator, a heat sink and a cross-flow fan, and is also provided with an air inlet and an air outlet. The cross-flow fan inhales air through the air inlet and then discharges it through the air outlet. When the air passes through the heat sink, it is heated or cooled, so that hot air or cold air can be blown out. The air inlet corresponding to the existing air conditioner indoor unit is a grid-like structure, and a filter is installed inside to filter impurities in the incoming air and prevent dust accumulation in the cross-flow fan and various internal devices, resulting in problems such as poor operation and noise. Since the air inlet is an open structure, in the off-season of air conditioning use, many families usually make an air conditioner cover to seal the air inlet in order to prevent air dust from entering. The air conditioner cover is generally made of fiber cloth. Although it has a certain degree of air permeability, it cannot meet the needs of air intake. Therefore, the air conditioner cover needs to be removed when the air conditioner is turned on, otherwise the air conditioner will not feel the weight even at the maximum wind speed. The indoor unit is usually hung at a high place, and it is troublesome to frequently disassemble and install the air conditioner cover. Moreover, the filter screen also needs to be disassembled for cleaning after long-term use. The existing indoor unit is a full shell structure, which is difficult to disassemble. It is necessary to make an appointment with a professional air conditioner master to operate. When there is heavy dust, the filter screen generally needs to be cleaned every two months. Therefore, the utility model improves the air inlet of the indoor unit of the air conditioner, adds an automatic baffle, and facilitates the removal of the filter screen structure and the dust cleaning operation.

[0019] The upper back side of the shell 1 has an arc portion, and the back side corresponding to the shell corresponds to the wall. The back side also has a hanging part for installing and fixing the inner hanging machine as a whole, and for the arc-shaped transition between the back side and the upper side. The arc portion has an air inlet slot 12 in a grille-like manner. The air inlet slot is composed of a plurality of strip-shaped slots arranged in sequence along the length direction of the inner hanging machine. The air inlet slot connects the inside and outside of the inner and outer machines, and is equipped with a filter 3 to block the air inlet slot 12. When the air is taken in, the filter is used to filter impurities in the air, and the impurities include dust, flocs, hair, poplar fluff, etc. The filter 3 is detachably installed. The filter that is used for a long time or when there are more impurities in the air needs to be removed for cleaning to ensure the permeability of the filter holes. Therefore, the filter is detachably installed. A dust shield 2 is also installed on the arc portion. The dust shield 2 is used to cover the air inlet slot 12 and is flipped to block the air inlet slot 12 or open the air inlet slot 12. During the off-seasons of spring and autumn when the air conditioner is used less, including when the air conditioner is not in use, the dust shield automatically rotates and covers the air inlet slot to prevent dust from entering the interior of the built-in unit. When the air conditioner is started, the drive device of the dust shield is started first to drive the dust shield to flip, and then other internal devices operate in sequence. When the air conditioner is turned off, the dust shield flips and covers the air inlet slot to prevent dust in the air from being adsorbed on the filter surface. At the same time, the filter is set on the outside of the built-in unit. When the dust shield is opened, the filter can be easily removed for cleaning to ensure efficient air permeability of the air inlet slot.

[0020] like Figure 3-4As shown: the position of the arc surface corresponding to the air inlet slot 12 has a step groove 13 for accommodating the filter 3 and the dust shield 2. When the dust shield is released and blocks the air inlet slot, the outer wall of the whole inner hanging machine has a smooth surface, which is more beautiful and convenient for installation and surface cleaning. The step groove 13 corresponds to the back side of the shell 1 and is provided with a receiving groove 14 for accommodating the dust shield 2. The dust shield 2 is an arc-shaped plate structure with the same curvature as the arc surface. It is used to store the dust shield. When the dust shield is in the storage state, there is no protruding part corresponding to the shell. At the same time, the back side of the shell is the installation side, and there is no extra space to accommodate the dust shield. The dust shield 2 has side plates 21 on both sides, one side of the side plate 21 has a shaft sleeve 22, and the other side has a gear sleeve 23, which is used to cooperate with the driving motor to realize the flipping of the dust shield 2. The inner hanging machine has a corresponding shaft seat inside, which is used for the shaft sleeve and the gear sleeve to be connected and rotated. The inner hanging machine also has a motor inside, and the output end of the motor has a gear, which is used to cooperate with the outer teeth of the gear sleeve to drive the dust shield to rotate. The flip side of the dust shield plate 2 is provided with a limit plate 24 for cooperating with the step groove 13 to limit the flip position of the dust shield plate 2.

[0021] like Figure 3 As shown: the filter 3 is a soft net with a magnetic strip 31 on the side, and a magnetically adsorbed metal strip 4 is fixed inside the step groove 13. The magnetic strip can fix the filter and provide support. The filter can be deformed into an arc to cover the air inlet slot, which is convenient for disassembly and installation.
