The air deflector 12 is located at the front upper part of the flow guiding plate 50, that is, the air deflector 12 is located at a position close to the upper air duct wall of the air outlet duct 11.
The drainage plate 50 is arranged below the air outlet, and the drainage plate 50 and the bottom of the shell 10 form a drainage air duct for guiding in air flow outside the indoor unit of the air conditioner, so that the air flow discharged from the indoor unit of the air conditioner is mixed with the air flow outside the indoor unit of the air conditioner and then is discharged. In this embodiment, the flow guide plate 50 also extends in the lateral direction of the wall-mounted air conditioning indoor unit, and has a length equal to the extension length of the indoor unit casing. The flow guide plate 50 is disposed below and behind the air guide plate 12, that is, the flow guide plate 50 and the air guide plate 12 have a certain distance therebetween in the front-rear direction and the height direction. The function of the flow guide plate 50 is to introduce the airflow outside the indoor unit and mix the airflow flowing out of the indoor unit to form mixed airflow (as shown in the schematic airflow diagram of fig. 2). When increasing the air output, use indoor air with by the cold air that the air outlet sent out for supply air current temperature is suitable, reaches and lets the comfortable effect of user's body feel. In the present embodiment, the flow guide plate 50 is movably disposed below the air outlet. In other embodiments of the present invention, the flow-guiding plate 50 may also be fixedly disposed below the air outlet, i.e. the flow-guiding plate 50 is always kept at one position (i.e. the first preset position).
In this embodiment, the extension plate 40 connects the casing and the lateral center of the flow-guiding plate 50, and is used to drive the flow-guiding plate 50 to move relative to the casing 10, so as to adjust the working position of the flow-guiding plate 50 according to the working state of the air conditioning indoor unit. The one end of expansion plate 40 is located inside casing 10, and can move inside casing 10, and the horizontal central authorities of casing and drainage plate 50 are connected to the other end of expansion plate 40 to guarantee that drainage plate 50 can the steady motion. The air conditioning indoor unit of this embodiment further includes: a motor and a gear 15. The motor is fixedly arranged in the shell, and the gear is arranged at the output end of the motor. One side of the telescopic plate 40 is provided with a rack 41, the telescopic plate 40 is engaged with the gear 15 through the rack 41, and the motor is configured to drive the telescopic plate 40 to move.
The cross section of the drainage plate 50 is oval, and the upper surface of the drainage plate is a convex curved surface, so that the drainage effect can be improved. When the indoor unit of the air conditioner is started, the expansion plate 40 drives the flow guide plate to extend to the first preset position, as shown in fig. 2, 3 and 5. The first preset position is specifically set as: as shown in fig. 2, the included angle α between the major axis of the ellipse of the cross section of the flow guide plate 50 and the horizontal plane is 10 ° to 20 °, and the length L1 from the center of the cross section of the flow guide plate to the wall where the wall-mounted indoor unit of an air conditioner is installed is 60mm to 80 mm. The width L2 of the air guide duct is set to be 20mm to 30mm, that is, the distance between the upper surface of the air guide plate 50 and the lower surface of the casing 10 is set to be 20mm to 30 mm. Through a plurality of experiments, the inventor finds that when the drainage plate 50 is set to the first preset position, the drainage effect is optimal.
The expansion plate 40 is further configured to drive the drainage plate 50 to retract to a second predetermined position when the wall-mounted air conditioning indoor unit is turned off. The air deflector 12 is also configured to rotate to a third predetermined angle when the wall-mounted air conditioning indoor unit is turned off, so as to cooperate with the flow guide plate 50 to close the air outlet. The second preset position is specifically set as: as shown in fig. 4, one end of the long axis of the flow guide plate 50 abuts against the lower edge of the air outlet, and the flow guide plate 50 is in a horizontal state. The third preset angle can be about 45 degrees of included angle between the air deflector and the vertical direction, and the upper edge of the air deflector protrudes out of the lower edge, so that the upper edge of the air deflector abuts against the upper edge of the air outlet, and the lower edge of the air deflector abuts against the drainage plate 50.

In the air conditioning indoor unit of the present embodiment, when the air conditioning indoor unit is turned off, the flow guide plate 50 is retracted to be flush with the air guide plate 12, and the air outlet is closed together, as shown in fig. 4. This state both can shelter from the gap of air outlet department, blocks that the dust gets into in the organism, also can block that the dust falls the drainage face of drainage plate 50, influences air cleanliness factor for indoor set appearance is more complete, pleasing to the eye simultaneously.
The air deflector is also configured to rotate to a first preset angle when the air conditioner is in a refrigerating state so as to allow airflow outside the indoor unit of the air conditioner to enter the drainage air duct; when the air conditioner is in a heating state, the air conditioner rotates to a second preset angle so as to prevent air flow outside the indoor unit of the air conditioner from entering the drainage air duct. The first preset angle is set to be an included angle between the air deflector and the horizontal direction smaller than 30 degrees, as shown in fig. 2. That is, when the air deflector rotates to the first preset angle, the air deflector is almost horizontally arranged. The second preset angle is set to be smaller than 30 degrees from the vertical direction, as shown in fig. 3. That is, when the air deflection plate is rotated to a second preset angle, the air deflection plate is disposed almost vertically.
When the indoor unit is refrigerating, the air deflector 12 rotates to a first preset angle, and the air deflector 12 controls the air outlet direction to go upwards (namely, to be close to horizontal air outlet). The exit in drainage wind channel produces the negative pressure, and above-mentioned negative pressure can drive the indoor ambient air at drainage wind channel rear portion and get into this drainage wind channel and the air-out of air outlet mixes, and the increase air output, this kind of natural wind mixes with the refrigeration wind simultaneously, makes the air-out softer, and the user can experience the air supply temperature suitable, can not have the sensation of subcooling. When the indoor unit heats, the air deflector 12 rotates to a second preset angle, and the air deflector 12 controls the air outlet direction to move downwards (i.e. close to vertical air outlet). At this moment, drainage wind channel department also can produce the negative pressure, but because the air-out direction that heats is close to vertical direction, leads to above-mentioned negative pressure direction to push down along with the air that heats, and the negative pressure direction is pressed close to the 50 directions of drainage plate. Thereby the inclination of drainage plate 50 just in time blocks indoor ambient air and gets into in the drainage wind channel, does not have the mixed wind when heating like this, and the air-out temperature can not reduce, can reach the effect of heating fast. In the air-conditioning indoor unit of the embodiment, the drainage plate 50 is arranged below the air supply outlet and can be matched with the air guide plate 12 for use, so that mixed air supply can be realized during refrigeration, mixed air supply can be avoided during heating, the use comfort of a user is enhanced, and the user experience is improved.
