In order to solve the above problem, the present invention provides a wall-mounted air conditioner indoor unit 100, and the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 8. As shown in fig. 1 in conjunction with fig. 2 and 3, the wall-mounted air conditioner indoor unit 100 may generally include: a housing 10 and a swirl actuator 30.

Specifically, as shown in fig. 2, the housing 10 has an inlet 101 and an outlet 102, and the airflow can flow from the inlet 101 to the outlet 102.

As shown in fig. 4, 5 and 6, the swirl regulator 30 is provided at the air outlet 102, the swirl regulator 30 includes a first bracket 31 and a plurality of regulating blades 32, the first bracket 31 is annular, the plurality of regulating blades 32 are rotatably connected to the first bracket 31, the plurality of regulating blades 32 extend in a radial direction of the first bracket 31, and the plurality of regulating blades 32 are arranged in a divergent manner in a circumferential direction of the first bracket 31. The adjusting blades 32 are mounted on the first bracket 31, shaft holes are formed in the shaft ends of the adjusting blades 32 and the first bracket 31 for connection, the adjusting blades 32 can rotate around the shaft ends, a certain number of the adjusting blades 32 are combined to form swirl blades 211, when all the adjusting blades 32 are in a state perpendicular to the axis of the first bracket 31, the whole air inlet is in a closed state, and when all the adjusting blades 32 rotate around the shaft and are in a state parallel to the axis of the first bracket 31, the air outlet is in a maximum air outlet state; when the adjustment blade 32 is rotated to the neutral position, it is possible to direct the wind to different positions and to generate a swirling air flow, which makes the air conditioning air flow more uniformly to various positions in the room.

In some embodiments, as shown in fig. 1, 4, 5 and 6, the swirl regulator 30 further comprises a second bracket 33, the second bracket 33 is annular, a central axis of the first bracket 31 and a central axis of the second bracket 33 coincide, the second bracket 33 surrounds the first bracket 31, the regulating blade 32 is rotatably disposed between the first bracket 31 and the second bracket 33, and both ends of the regulating blade 32 are rotatably connected to the first bracket 31 and the second bracket 33, respectively. By providing the second bracket 33 and disposing the regulating blade 32 between the first bracket 31 and the second bracket 33, the connection stability of the regulating blade 32 can be improved.

In some embodiments, as shown in fig. 1, 4, 5 and 6, the adjusting blade 32 has a flat surface shape, and the width of the adjusting blade 32 gradually increases in a direction from the first bracket 31 to the second bracket 33.

In some embodiments, as shown in FIG. 5, the swirl actuator 30 further includes a drive member 34, the drive member 34 being coupled to the adjustment vane 32 and adapted to drive the adjustment vane 32 to rotate. Through setting up drive disk assembly 34, drive disk assembly 34 drive adjusts blade 32 and takes place to rotate, can adjust the opening angle of adjusting blade 32 to adjust air-out area and air-out angle. Preferably, the transmission member 34 is disposed inside the circular ring of the first bracket 31, whereby the integrity of the swirl regulator 30 can be improved. Further preferably, the transmission member 34 is circular, so that the air outlet area of the wall-mounted air conditioner indoor unit 100 can be increased, and the wind resistance can be reduced.

In some embodiments, as shown in fig. 2, the air outlet 102 is opened on the front panel 11 of the casing 10, and the air inlet 101 is provided at least one of the top panel 12 and the bottom panel 13 of the casing 10. For example, the air inlet 101 may be disposed only on the top plate 12, the air inlet 101 may also be disposed only on the bottom plate 13, and the air inlet 101 may also be disposed on both the top plate 12 and the bottom plate 13 to increase the air inlet area, thereby increasing the air inlet volume and further improving the heat exchange efficiency. The air flow flows from the air inlet 101 to the air outlet 102, that is, the air flow enters the casing 10 from the top plate 12 or the bottom plate 13, exchanges heat, and is blown out from the front panel 11, so that the air-conditioning air flow is blown out forward.

In some embodiments, a partition is disposed in the casing 10, the partition and the casing 10 define a plurality of independent air ducts, the air ducts are communicated with the air inlet 101 and the air outlet 102, a fan 20 is disposed in each air duct, and the fan 20 is located upstream of the swirl regulator 30 in the air outlet direction. Also, the fans 20 correspond to the air ducts one to one, when the fans operate, air enters the casing from the air inlet 101, enters the plurality of mutually independent air ducts after heat exchange of the heat exchanger 40, and the fans 20 are arranged in each independent air duct, so that air robbery during simultaneous operation of the plurality of fans 20 can be effectively avoided, and then the air flows out of the air outlet 102. It can be understood that, when a plurality of fans 20 are operated, once the phenomenon of eddy current occurs during wind rush, not only can relatively large noise be generated, but also the air volume can be reduced. Further, the reduction of the air volume also affects the heat exchange efficiency of the heat exchanger 40, resulting in a reduction of the cooling capacity of the air conditioner.

Specifically, taking two fans 20 as an example, when the two fans 20 compete with each other, the airflow sandwiched between the two fans 20 is likely to generate a vortex, and in addition, no matter which fan 20 obtains a larger amount of air, the amount of air sandwiched between the two fans 20 is inevitably reduced, so that when the airflow sandwiched between the two fans 20 passes through the heat exchanger 40, sufficient cold energy cannot be absorbed, which causes the heat exchange efficiency of the heat exchanger 40 to decrease, and in addition, the heat exchange of the heat exchanger 40 is also uneven.

Because this application the baffle sets up two at least wind channels into mutual independence, can avoid appearing robbing the wind phenomenon, from this, can avoid the production of vortex phenomenon to noise reduction increases the amount of wind and improves heat exchange efficiency.

Further, as shown in fig. 1 in conjunction with fig. 7 and 8, a plurality of wind turbines 20 are arranged side by side in the casing 10, wherein axes of the plurality of wind turbines 20 are parallel to each other, the wind turbines 20 include a motor and a wind wheel, and a line of the plurality of wind wheels 21 is perpendicular to an axis of any one of the plurality of wind wheels 21.

From this, according to the utility model discloses wall-hanging air conditioner indoor unit, a plurality of wind channels are injectd to baffle and casing, and at least two in a plurality of fans 20 are located different wind channels, can avoid a plurality of fans 20 to snatch the wind each other, have improved the amount of wind and have reduced the noise.

In some embodiments, as shown in fig. 1, a plurality of air outlets 102 are spaced on the casing 10, each air outlet 102 is provided with a swirl regulator 30, and the plurality of air outlets 102 correspond to the plurality of fans 20 one by one. Through setting up a plurality of air outlets 102 that the interval was arranged, also a plurality of fans 20 interval is arranged, can avoid appearing robbing wind or the condition of fan 20 mutual interference. Under the driving action of the motor 22, the wind wheel 21 rotates, airflow enters the housing 10 from the air inlet 101, and flows out from the air outlet 102 corresponding to the wind wheel 21 after passing through the wind wheel 21, so that the situation that the airflow blown out from the air inlet 101 is disordered due to mutual interference of a plurality of fans 20 can be avoided.

In some embodiments, as shown in fig. 7 and 8, at least two of the plurality of rotors 21 have different numbers of blades 211. In other words, the number of blades 211 of at least one of the plurality of wind turbines 21 is different from the number of other wind turbines 21. It can be understood that, when the blades 211 of the wind wheels 21 are the same, the wind wheels 21 rotate at the same time, so that the resonance condition is easy to occur, and the number of the blades 211 of at least two of the wind wheels 21 is set to be different, so that the resonance condition can be effectively avoided, and the noise is reduced.

Preferably, the number of blades 211 of each of the plurality of wind wheels 21 is different from the number of other blades 211.

Further preferably, the number of the blades 211 of the plurality of wind wheels 21 does not have a multiple relationship of more than 2, for example, when the number of the blades 211 of one of the wind wheels 21 is 3, the number of the blades 211 of the other wind wheels 21 should be set to avoid the multiple of 3, thereby also avoiding the occurrence of resonance and reducing noise.

In some embodiments, as shown in fig. 2 and fig. 3, the plurality of motors 22 are connected to the plurality of wind wheels 21 in a one-to-one correspondence, and the wind wheels 21 are located on a side of the corresponding motors 22 far away from the air outlet 102. It can be understood that the wind wheel 21 is close to the wind outlet 102, and the noise is relatively high because the speed of the airflow just after the airflow leaves the wind wheel 21 is relatively high, the size of the vortex formed by the airflow hitting other objects is large, and the vortex is relatively noisy when the vortex is broken. In order to avoid noise generation, the wind wheel 21 of the motor 22 is arranged on one side of the motor 22 far away from the air outlet 102, and the effect of reducing the thickness of the machine body can be achieved.

In some alternative embodiments, as shown in fig. 2 and 3 in combination with fig. 7 and 8, the hub 212 of the wind wheel 21 has a receiving cavity 213 that is open toward the air outlet 102, and the diameter of the hub 212 is larger than that of the motor 22, and at least a portion of the motor 22 is disposed in the receiving cavity 213. Therefore, the thickness of the body can be further reduced, which is beneficial to the miniaturization of the wall-mounted air conditioner indoor unit 100.

In some embodiments, the blades 211 of at least two of the plurality of wind turbines 21 are rotated in opposite directions, and the wind blowing directions of the plurality of wind turbines 21 are the same. As shown in fig. 7 and 8, the rotation directions of the blades 211 of at least two of the wind wheels 21 are opposite, wherein the rotation direction of the blades 211, that is, the twisting direction of the blades 211, is understood that the wind outlet direction of the fan 20 is related to the rotation direction of the motor 22, and the amount of the wind supplied by the fan 20 is related to the twisting direction of the blades 211, for example, in the case that the rotation directions of the blades 211 are the same, when the motor 22 rotates forward, the wind outlet amount is about 100, and when the motor 22 rotates backward, the wind outlet amount is about 50.

In the present application, as shown in fig. 7 and 8, the rotation directions of at least two blades 211 of the plurality of wind wheels 21 are opposite, and the air supply directions of the plurality of wind wheels 21 are the same, that is, the rotation directions of the plurality of wind wheels 21 are the same, for example, the plurality of fans 20 rotate forward at the same time, the airflow flows from the air inlet 101 to the air outlet 102, the plurality of fans 20 rotate backward at the same time, and the airflow flows in the reverse direction.

It can be understood that, taking the wall-mounted air conditioner indoor unit 100 as an example for changing the air supply direction in a no-wind-feeling state, specifically, the wall-mounted air conditioner indoor unit has three fans, the three fans have three wind wheels 21, the rotation direction of the blade 211 of one of the three wind wheels 21 is opposite to that of the blades of the other two wind wheels 21, in the normal mode, the three motors 22 rotate forward, the airflow flows from the air inlet 101 to the air outlet 102, the total air volume is 2 × 100+50 ═ 250, in the no-wind mode, the three fans 20 are reversed, the airflow is reversed, and the total wind rate is 2 × 50+100 to 200, as can be seen, in the no-wind mode, the change of the wind volume of the wall-mounted air conditioner indoor unit 100 is small, and the situation of insufficient refrigerating capacity does not occur, therefore, the condition that the wall-mounted air conditioner indoor unit 100 frequently exits the no-wind-sense mode can be avoided, and the comfort is improved.

From this, according to the utility model discloses a wall-hanging air conditioner indoor unit 100, two at least blades 211 among a plurality of wind wheels 21 revolve to opposite, and a plurality of wind wheels 21's air supply direction is the same, and wall-hanging air conditioner indoor unit 100 is under the mode of operation of difference, and the refrigerating output change is little, and stability is higher, is favorable to improving user's travelling comfort.

In alternative embodiments, as shown in fig. 2, 3, 7 and 8, the outer surface of the hub 212 flares in a direction proximate the outlet 102. In other words, the wind wheel 21 is an oblique flow wind wheel 21, and the airflow using the oblique flow wind wheel 21 flows very uniformly and smoothly with less eddy current loss. Mainly because the airflow gradually changes from axial direction to oblique entering flow channel, and slowly changes to radial direction after coming out from the wind wheel 21 outlet. This results in less flow losses inside the diagonal flow fan 20. In addition, because the design of the blades 211 conforms to the ternary flow rule, the impact loss of the inlet of the fan 20 can be ensured to be small, the pressure and the speed of the outlet of the fan 20 are kept uniform in the width direction, the relative speed of the air flow can be improved, and the efficiency of the fan 20 is further improved.
