In the following description, the orientations or positional relationships of "front", "back", "upper", "lower", "top", "bottom", "inside", "outer", "lateral", etc. are based on The orientation or positional relationship shown in the figures is for the convenience of the description of the invention and the simplification of the description, and is not intended to indicate or imply that the device or component referred to has a specific orientation, is constructed and operated in a specific orientation, and therefore cannot be construed as a Limitations of the invention.

1 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, FIG. 2 is a front view of the wall-mounted air conditioner indoor unit shown in FIG. 1, and FIG. 3 is a side cross-sectional view of the wall-mounted air conditioner indoor unit shown in FIG. . The wind direction is indicated by arrows in Figures 2 and 3. As shown in FIG. 1 to FIG. 3, the wall-mounted air conditioner indoor unit of the embodiment of the present invention may generally include a housing 100, an evaporator 200, a fan 300, a drain 600, and a draining flap assembly. The wall-mounted air conditioner indoor unit and the air conditioner outdoor unit (not shown) constitute a vapor compression refrigeration cycle system, and realize cooling/heating of the indoor environment. The top of the housing 100 has an air inlet 101, and the bottom front side has an air outlet 102 that extends toward the front lower side and extends in the lateral direction. The air inlet 101 is for allowing air in the indoor environment to enter the interior of the casing 100, and the air outlet 102 is for supplying air to the indoor environment. The housing 100 may be an elongated structure extending in a lateral direction (ie, a left-right direction). The air outlet 102 may be an elongated opening extending in the lateral direction. The air outlet 102 is opened at the bottom of the casing 100 and faces forward and downward to facilitate the downward air supply when the wall-mounted air conditioner indoor unit is mounted on the wall.

The evaporator 200 is disposed in the casing 100 for heat exchange with air entering the casing 100 from the air inlet 101 to form heat exchange wind (specifically, cold air during cooling and hot air when heating).

A main air duct 110 is disposed in the casing 100, and a front edge of the main air duct 110 constitutes an air outlet 102. The main air duct 110 is used to drain the heat exchange air from the evaporator 200 to the air outlet 102, and to cool the room to achieve cooling/heating.

The fan 300 is disposed within the main duct 110 and is configured to cause air to flow from the evaporator 200 to the air outlet 102, i.e., to provide power for the wind to blow from the air outlet 102 into the room. The blower 300 is preferably a cross flow fan that extends in the lateral direction with respect to the central axis of rotation. The evaporator 200 is preferably a three-stage evaporator covering the space in front of and above the cross-flow fan 300, and further may be a fin-type evaporator.

The number of the fans 300 may be one or plural. For example, the number of fans 300 can be two and are cross-flow fans, and the central axes of rotation of the two cross-flow fans extend in a lateral direction and are collinearly disposed. Correspondingly, the number of air outlets 102 is also two, and the position of each air outlet 102 corresponds to a cross flow fan. Two cross-flow fans are provided to enrich the air supply mode. For example, when the air volume is small, only one cross flow fan can be turned on. When the air volume demand is large, two cross flow fans can be turned on at the same time. Moreover, when the two cross flow fans are simultaneously turned on, the wind direction can also be set differently to simultaneously supply air to the two areas.

The flow guiding member 600 is an elongated structure, and the longitudinal direction thereof is disposed laterally below the bottom of the housing 100 to define a mixed air duct 601 with the bottom of the housing 100 to allow the indoor air under the housing 100 to be mixed. The wind tunnel 601 flows to the air outlet 102, mixes with the heat exchange air to form a mixed air, and blows into the room. The arrows in Figs. 2 and 3 generally indicate the wind direction.

The plurality of drainages When the swinging blade 710 is synchronously oscillated, the airflow direction of the mixed air duct 601 can be changed.

In the embodiment of the present invention, the outlet of the mixed air duct 601 is located below the air outlet 102. When the heat exchange air is blown out from the air outlet 102, the lower side edge of the air outlet 102 forms a negative pressure, and the air in the air mix duct 601 can be sucked, so that the indoor air below the casing 100 flows continuously through the air duct 601. The tuyere 102 is mixed with the heat exchanged air to form a mixed flow of wind and then blown into the room. In the cooling mode, the temperature of the mixed-flow wind is higher than that of the heat-exchanged wind, and in the heating mode, the temperature of the mixed-flow wind is lower than that of the heat-exchanged wind. The invention can avoid the heat exchange wind which is too low or too high to be blown to the human body, causing human discomfort. In short, the air-conditioning indoor unit blows the mixed-flow wind into the room, which will make the wind softer, improve the comfort of the air supply, and improve the user's wind experience. At the same time, since the additional indoor air is mixed into the heat exchange air, the total air volume of the air outlet 102 is increased, and the cooling/heating speed is accelerated.

In addition, in the embodiment of the present invention, the airflow direction of the mixed air duct 601 can be adjusted by synchronously rotating the plurality of draining vanes 710, that is, the wind direction of the mixed air duct 601 is changed. Therefore, it is convenient to adjust the direction of the indoor air to enter the heat exchange wind by changing the wind direction of the mixed air duct 601, so as to facilitate the mixing of the two, so that the two are mixed more uniformly.

The arrangement of the drainage pendulum assembly can also enable the air-conditioning indoor unit to achieve a mixed air effect on the lateral side at the same time, and achieve a strong air supply without mixed flow on the other side of the lateral direction, thereby improving the air supply experience. As shown in FIG. 2, the drainage pendulum 710 can guide the airflow of the mixed air duct 601 to the right side, so that the air-conditioning indoor unit realizes the mixed air effect on the right side at the same time, and realizes the strong air supply without the mixed flow on the left side.

The motor 740 is mounted to the flow guide 600 with its axis of rotation parallel to the pivot axis of the guide vane 710 and to the other end 731 of the rocker 730. The rotation of the rotating shaft of the motor 740 can drive the rocker 730 to swing, so as to drive the connecting rod 720 to reciprocate along its length direction, thereby driving the plurality of guiding swing blades 710 to synchronously swing.

The inside of the drainage member 600 may have a receiving cavity. The bottom of the drainage pendulum 710 extends through the retaining hole 621 of the drainage member 600 (FIG. 6) into the receiving cavity and is hinged to the top wall of the receiving cavity.
