Referring to fig. 1, a wall-mounted air conditioning indoor unit 100 may generally include a casing 110, an indoor unit heat exchanger 120 and an indoor unit blower 130 disposed in the casing 110. A top air inlet 111 is formed at the top of the casing 110, an air outlet extending along the transverse direction of the indoor unit 100 is formed at the lower portion of the casing 110, an air outlet duct 140 communicating with the air outlet is provided inside the casing 110, and the air outlet duct 140 is defined by an upper duct wall 141 and a lower duct wall 142. The indoor unit heat exchanger 120 may be configured to exchange heat with air flowing therethrough to change the temperature of the air flowing therethrough into heat-exchanged air. The indoor unit fan 130 may be configured to cause indoor air entering from the top air inlet 111 to flow toward the indoor unit heat exchanger 120, and to cause heat-exchanged air after heat exchange by the indoor unit heat exchanger 120 to flow toward the air outlet via the air outlet duct 140. The lateral direction refers to a direction in which the length of the indoor unit 100 extends.
In particular, the wall-mounted air conditioning indoor unit 100 of the present embodiment further includes a wind deflector 150, and the wind deflector 150 includes at least two plate sections that are rotatably connected from top to bottom. The air deflector 150 has a first position retracting into the air outlet duct 140 and a second position moving out of the air outlet duct 140, the air deflector 150 is configured to be controlled to translate between the first position and the second position, and in the process that the air deflector 150 translates from the first position to the second position, the air outlet is exposed, when the air deflector 150 is at the first position, the plate section at the lowest part covers the air outlet, and the rest plate sections are located in the air outlet duct 140; when the air guiding plate 150 is located at the second position, each plate segment is configured to be controlled to rotate around an axis parallel to the extending direction of the air outlet, and when one plate segment rotates, all other plate segments connected to the lower end of the plate segment are driven to rotate, so as to adjust the air outlet direction and the air outlet area.
When the air deflector 150 is moved out of the air outlet duct 140 in a translational manner, the air deflector 150 can be rotated to a plurality of different positions, so that the air outlet direction and the air outlet area can be adjusted under different conditions. The air deflector 150 can stay at any position of the translation path in the translation process between the first position and the second position, so that the air outlet direction and the air outlet area can be adjusted in the translation process of the air deflector 150. Therefore, the air conditioner indoor unit 100 can reasonably adjust the air outlet direction and the air outlet area according to different operation conditions, improves the diversity of air outlet, meets the diversity requirements of users, and improves the comfort of the users.
Before the air deflector 150 translates from the second position to the first position, the air deflector 150 is configured to rotate to an initial position at which the plate section located at the lowermost portion is opposite to the air outlet, that is, before the air deflector 150 translates from the second position located outside the air outlet duct 140 to the first position retracted to the air outlet duct 140, the air deflector 150 first needs to rotate from the current position state to a position at which the plate section located at the lowermost portion of the air deflector 150 is opposite to the air outlet, which is marked as the initial position at which the air deflector 150 is located at the second position, and after the air deflector 150 rotates to the initial position, the air deflector 150 translates and retracts into the air outlet duct 140, so as to ensure that the plate section located at the lowermost portion of the air deflector 150 just covers the air outlet when the air deflector 150 translates into the air outlet duct 140.
In the actual operation of the indoor air conditioner 100, after a control instruction of the air deflector 150 for translating to the first position is received, the position state of the air deflector 150 at the moment is detected, if the position state of the air deflector 150 at the moment is not the initial position, the air deflector 150 is controlled to rotate to the initial position, and then the air deflector is translated and retracted into the air outlet duct 140; if the position state of the air deflector 150 at this moment is the initial position, the air deflector 150 directly translates and retracts into the air outlet duct 140.
The operation state and the position state of the air deflector 150 of the indoor unit 100 of the air conditioner can be realized by a remote controller, so that a user can conveniently and reasonably adjust the position of the air deflector 150 according to the requirement of the user, and a more comfortable air supply effect can be obtained.
The uppermost plate segment is formed with a plurality of air dispersing holes 151d penetrating the plate segment in the thickness direction. Each of the air dispersing holes 151d extends in the thickness direction of the uppermost plate segment to form air dispersing small holes; or each of the air dispersing holes 151d extends in a length direction of the uppermost plate segment to form a bar-shaped air dispersing hole, or referred to as an air dispersing bar. When the air deflector 150 is at the second position, most of the air flow flows along the inner surface of the air deflector 150, and a small part of the air flow can flow outwards through the air dispersing holes 151d on the plate section to form breeze air flow, so that the temperature of the air supply air flow is proper, and the effect of enabling a user to feel comfortable is achieved. Therefore, the problem that cold air is high in air speed and poor in experience when blown to a person during refrigeration is solved.
In one embodiment of the present invention, there are two plate sections, the two plate sections are an upper plate section 151 and a lower plate section 152 rotatably connected to a lower portion of the upper plate section 151, and the upper plate section 151 is formed with air dispersing holes 151 d. When the air guiding plate 150 is at the first position, the upper plate segment 151 is located inside the air outlet duct 140, and the lower plate segment 152 covers the air outlet. When the air deflector 150 is at the second position, the upper plate segment 151 is configured to controllably rotate around an axis parallel to the extending direction of the air outlet, and simultaneously drives the lower plate segment 152 to rotate; the lower plate segment 151 is also configured to be controlled to independently rotate around an axis parallel to the extending direction of the air outlet, so that different position states of the air deflector 150 at the second position are changed, the air outlet direction and the air outlet area are flexibly adjusted, and flexible and diversified control of the air flow direction is realized.
It is understood that the upper plate segment 151 and the lower plate segment 152 may both extend along the length direction of the air outlet, and the upper plate segment 151 and the lower plate segment 152 may extend from one end to the other end of the length direction of the air outlet.
The width of the lower plate section 152 may be substantially the same as the width of the air outlet, so that when the air guiding plate 150 retracts into the air outlet duct 140, the lower plate section 152 may just cover the air outlet, and the outer surface of the lower plate section 152 is flush with the bottom end of the casing 110, so that the air outlet is more beautiful when closed.
As shown in fig. 2, when the air guiding plate 150 is at the second position, the lower plate 152 rotates upward to realize upward blowing, which is beneficial to refrigeration and avoids the problem of poor experience caused by direct blowing of cold air to the human body.
As shown in fig. 3, when the air deflector 150 is at the second position, the upper plate segment 151 and the lower plate segment 152 are configured to be rotatable to make the lower plate segment 152 abut against the upper air duct wall 141 of the air outlet duct 140 to close the air outlet, that is, after the air deflector 150 is moved out of the air outlet duct 140, the lower plate segment 152 is rotatable to make the lower plate segment 152 abut against the upper air duct wall 141 of the air outlet duct 140, the air deflector 150 at the position can just shield the air outlet, so that the air outlet can be shielded outside the air outlet duct 140, and the air flow can only flow outwards through the air dispersing holes 151d of the upper plate segment 151 to form a breeze flow, so that the temperature of the supply air flow is suitable.
For example, when a user has a rest at night, the air deflector 150 may be rotated to a position where the lower plate section 152 abuts against the upper air duct wall 141 of the air outlet duct 140, the air deflector 150 in the position can just shield the air outlet, and the air flow flows outwards only through the air dispersing holes 151d of the upper plate section 151 to form a breeze air flow, so that the user can always feel that the breeze blows, the temperature of the supplied air flow is proper, the user does not feel that the temperature is too low, and the comfort of the user is improved.
The air conditioner indoor unit 100 of this embodiment can change the air-out mode of multiple differences through the adjustment of upper plate section 151 rotational position and the adjustment of lower plate section 152 rotational position, adapts to the different operating conditions of indoor unit 100, satisfies user's diversified demand, is convenient for provide more comfortable experience for the user.

In one embodiment of the present invention, referring again to fig. 1, the housing 110 includes a top plate disposed in a substantially horizontal direction and a rear inclined plate connected to and extending rearward and downward from a rear edge of the top plate. A top intake port 111 is formed on the top plate, a rear intake port 112 is formed on the rear inclined plate, and an air outlet is formed at the bottom of the housing 110. Indoor air enters the indoor unit 100 through the top air inlet 111 and the rear air inlet 112, exchanges heat with the indoor unit heat exchanger 120, flows out of the indoor unit 100 through the air outlet duct 140, and enters the room, so that the indoor temperature is adjusted.
The indoor heat exchanger 120 comprises a first heat exchange section 121, a second heat exchange section 122 and a third heat exchange section 123 which are connected in sequence. The first heat exchange section 121 is located in front of the rear air inlet 121 and extends backwards and downwards, the second heat exchange section 122 is communicated with the first heat exchange section 121 and extends forwards and downwards from the top of the first heat exchange section 121, and the third heat exchange section 123 is communicated with the second heat exchange section 122 and extends vertically and downwards from the bottom of the second heat exchange section 122.

The air flow in the casing 110 exchanging heat with the multiple heat exchange sections completely enters through the top air inlet 111, which results in that the heat exchange section near the top air inlet 111 can directly exchange heat with the air flow entering through the top air inlet 111, and the heat exchange air flow of other heat exchange sections far away from the top air inlet 111 can reach these heat exchange sections only after passing through a narrow and long area.

In this embodiment, through all forming the air intake at roof and back swash plate, the air current air inlet mode is redistributed, third heat transfer section 123 and second heat transfer section 122 carry out the heat transfer with the air current that gets into through top air intake 111, first heat transfer section 121 carries out the heat transfer with the air current that gets into through rear portion air intake 112, the air current distribution is reasonable, the air inlet area enlarges, air current friction reduces, the air current distributes more evenly, the air current lift of first heat transfer section 121 obviously reduces, the air inlet angle is more reasonable, effectively reduce air conditioner noise.
The width of the top plate is 1/5 to 1/2 of the width of the housing 110. Optionally, the width of the top panel is 3/10 to 4/10 of the width of the housing 110. The ratio of the width of the top plate to the width of the housing 110 is in the range of 1/5 to 1/2, or in the range of 3/10 to 4/10. Therefore, the proportion of the top air inlet and the rear air inlet is further adjusted, the air inlet volume and the air inlet angle of different heat exchange sections of the indoor unit heat exchanger 120 in the shell can be more reasonably distributed, the air flow distribution is reasonable on the premise of ensuring the air inlet volume, the distribution is more uniform, the air flow friction is reduced, and the noise of the indoor unit 100 is effectively reduced.
The bottom end of the rear sloping plate intersects with a perpendicular line passing through the highest point of the lower air duct wall 142 and serving as a tangent line of the lower air duct wall 142, and the angle formed by the rear sloping plate and the horizontal plane can be 25-45 degrees. Therefore, the position of the rear inclined plane extending from the rear edge of the top plate to the rear lower part is limited, the proportion of the top air inlet 111 and the rear air inlet 112 is reasonably adjusted, the air inlet amount and the air inlet angle of the second heat exchange section 122 and the third heat exchange section 123 are reasonably distributed, the air inlet problem of the first heat exchange section 121 is solved, the air inlet area is improved, the air inlet windage resistance is reduced, the airflow lift is reduced, and the noise of the air conditioner is effectively reduced on the premise of ensuring the air inlet amount.

Moreover, a plurality of air dispersing holes 151d penetrating through the upper plate section in the thickness direction are formed in the uppermost plate section, and after the air deflector 150 is moved out of the air outlet duct 140, a small part of air flow is blown out through the air dispersing holes 151d on the plate section to form breeze air flow, so that the temperature of the supplied air flow is appropriate, and the user feels more comfortable. Therefore, the problem that cold air is high in air speed and poor in experience when blown to a person during refrigeration is solved.
