Embodiment Construction

[0048] figure 2 is a schematic sectional view of an air conditioner indoor unit 200 according to an embodiment of the present invention. see figure 2 , the air conditioner indoor unit 200 may include a casing 210 , a fan 220 and a heat exchanger 230 disposed in the casing 210 . The air conditioner indoor unit 200 may be a wall-mounted air conditioner indoor unit.

[0049] The casing 210 may include a frame for supporting the fan 220 and the heat exchanger 230, a casing covered on the frame, a panel connected to the front side of the casing to form the front of the casing 210, and a panel respectively arranged on the frame. Left and right end caps on both sides of the shell 210.

[0050] The casing may have an air inlet 211 at its top and an air outlet 212 at its bottom. An air inlet grille may be provided at the air inlet 211 , and indoor air enters the interior of the indoor unit 200 through the air inlet grille. The main air duct 213 connecting the air inlet 211 and t...

Abstract

The invention provides an air conditioner indoor unit. The air conditioner indoor unit comprises a machine shell, a fan and a flow guide plate, wherein an air inlet and an air outlet are arranged on the machine shell, the fan is arranged in the machine shell and promotes air to flow to the air outlet from the air inlet, the flow guide plate is arranged on an air supply flow path of the fan and comprises a first flow guide part and a second flow guide part, and the flow guide plate is configured to rotate around the horizontal direction so as to adjust the sequence of an air flow flowing through the first flow guide part and the second flow guide part. According to the air conditioner indoor unit, the flow guide plate comprises the first flow guide part and the second flow guide part with the flow guide face different from that of the first flow guide part, the effective flow guide area of an indoor unit body is increased, and the flow guide plate rotates around the horizontal direction, so that the sequence of the air flow flowing through the first flow guide part and the second flow guide part and the air guide angle of the first flow guide part or the second flow guide part located on the downstream can be adjusted, then combination of various air supply angles and air supply lifts is achieved, and user experience is improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning indoor unit. Background technique [0002] figure 1 is a schematic sectional view of an air conditioner indoor unit according to an embodiment in the prior art. see figure 1 , the air outlet of the existing wall-mounted air conditioner indoor unit 100 is mostly opened at the front bottom of its casing 110, and the air outlet is opened and closed by setting the wind deflector 140 and the flow direction of the airflow is adjusted in the vertical direction. However, affected by the fixed structure of the air guide plate 140 and the extension direction of the main air duct 113, the air guide direction of the air guide plate 140 is still inclined upward when the air guide plate 140 swings down to the limit position, and the upward swing will easily increase the wind resistance and cause refrigeration. Thermal efficiency becomes low. Considering comprehensively, ...
