Referring to fig. 1 to 4, a wall-mounted air conditioner indoor unit 1 of the present invention includes a cabinet 10, and the cabinet 10 is used to constitute a housing of the wall-mounted air conditioner indoor unit 1. The cabinet 10 has an air inlet 11 for introducing indoor air and an air outlet 12 extending in the lateral direction of the cabinet 10 for supplying air into the room, and two independent air deflectors 131, 132 arranged side by side in the lateral direction are provided at the air outlet 12. Each deflector is configured to be controllably pivoted about its own axis of rotation for adjusting the open and closed state and/or the direction of the air outlet 12 of the air outlet area corresponding to the deflector. Specifically, one of the air deflectors 131 may be located in a left area of the air outlet 12, for adjusting an open/close state and/or an air outlet direction of the left area of the air outlet 12; another air deflector 132 may be located at a right side region of the air outlet 12 for adjusting an open/closed state and/or an air outlet direction of the right side region of the air outlet 12.
In particular, the rotation shafts of the two air deflectors extend obliquely upward from both lateral side ends of the cabinet 10 toward the middle of the cabinet 10, respectively, so that the projections of the rotation shafts of the two air deflectors in a vertical plane perpendicular to the front-rear direction form an inverted V shape gradually inclined upward from both lateral side ends of the cabinet 10 toward the middle thereof. That is, the rotation shaft of one of the air deflectors 131 extends obliquely upward from one of the lateral side ends of the cabinet 10 toward the middle of the cabinet 10, and the rotation shaft of the other air deflector 132 extends obliquely upward from the other lateral side end of the cabinet 10 toward the middle of the cabinet 10, so that the rotation shafts of the two air deflectors enclose a substantially inverted V-shaped structure. Therefore, the distance between each air deflector and the air outlet 12 is gradually increased from the middle to the two sides, namely, the simple design of the arrangement mode of the two air deflectors breaks through the limitation of the traditional direct guiding mode of the air deflectors in the prior art on the air supply range of the indoor unit, the air supply wide angles of the swing blades and the air deflectors in the transverse direction are increased, and the air supply range of the indoor unit is enlarged.
Specifically, the wall-mounted air conditioning indoor unit 1 further includes two independent cross flow fans 21, 22, the cross flow fans 21 and 22 being disposed in the cabinet 10 side by side in the lateral direction, each configured to rotate about its own rotation axis in a controlled manner, the rotation axes of the two cross flow fans extending obliquely forward from the lateral ends of the cabinet 10 toward the middle of the cabinet 10, respectively, such that the projections of the rotation axes of the two cross flow fans in the horizontal plane form a V-shape gradually inclined forward from the lateral ends of the cabinet 10 toward the middle thereof, that is, the two cross flow fans 21, 22 enclose a V-shape gradually inclined forward from the lateral ends of the cabinet 10 toward the middle thereof. Specifically, the rotation shaft 211 of the cross flow fan 21 may extend obliquely forward from one lateral end portion of the casing 10 toward the middle portion of the casing 10, and the rotation shaft 221 of the cross flow fan 22 may extend obliquely forward from the other lateral end portion of the casing 10 toward the middle portion of the casing 10.
Because the two air deflectors are independent and the two cross flow fans are also independent, the state of each air deflector, the pivoting angle, the pivoting speed and other parameters can be set freely by a user, and the starting and stopping state, the rotating speed and other parameters of each cross flow fan can also be set freely by the user. The state of aviation baffle and the state of cross flow fan combine each other and have realized the two district air supply of multiple mode, have satisfied the different refrigeration heating demands of user in different regions, have improved user's use experience.

Specifically, when the fan motor at one side is in a running state, the air deflector at the side is in an open state so as to better match and adjust the air outlet direction of the side area of the air outlet.
Further, the wall-mounted air conditioner indoor unit 1 further includes an evaporator 30, and the evaporator 30 is configured to exchange heat with an air flow flowing therethrough, so as to generate a heat exchange air flow having a higher temperature (when heating) or a lower temperature (when cooling). Fig. 5 is a schematic structural view of an evaporator according to an embodiment of the present invention. The evaporator 30 is covered on the two cross-flow fans 21, 22, and includes a first heat exchange section 31, a second heat exchange section 32, and a third heat exchange section 33 that are sequentially connected from back to front.
