Referring to fig. 1 to 3, fig. 1 is a schematic view of a wall-mounted air conditioning indoor unit 1 according to an embodiment of the present utility model, fig. 2 is a sectional view of the wall-mounted air conditioning indoor unit 1 when an air guide 50 is in a drainage position according to an embodiment of the present utility model, and fig. 3 is a sectional view of the wall-mounted air conditioning indoor unit 1 when the air guide 50 is in a drainage position according to an embodiment of the present utility model.

The present utility model provides a wall-mounted air conditioner indoor unit 1, and the wall-mounted air conditioner indoor unit 1 may generally include a cabinet 10, an air duct frame 20, an evaporator 30, and a cross-flow fan 40.

The cabinet 10 protects the entire air conditioning indoor unit 1, and the rear side of the cabinet 10 is provided with an air-inlet grille on which a heat exchange air flow inlet 12 is formed, and the front lower side of the cabinet 10 is provided with a heat exchange air flow outlet 14 extending in a lateral direction. The heat exchange air flow outlet 14 can be further provided with an air deflector 16, and the air deflector 16 can be used for opening and closing the heat exchange air flow outlet 14 or adjusting the direction of the heat exchange air flow.

The air duct frame 20 is disposed inside the cabinet 10, a heat exchange air duct 222 is formed on the air duct frame 20, and the heat exchange air duct 222 has an air inlet side opened toward the heat exchange air flow inlet 12 and an air outlet side opened toward the heat exchange air flow outlet 14. The duct frame 20 also has an air outlet duct 224 connected between the air outlet side and the heat exchange air flow outlet 14 to guide the heat exchange air flow in the heat exchange air duct 222 to the heat exchange air flow outlet 14. A plurality of swing blades 226 can also be arranged in the air outlet duct 224 to adjust the direction of the heat exchange air flow through transverse swing.

The evaporator 30 is installed on the air duct frame 20 and covers the heat exchange air duct 222 to exchange heat with air sucked into the casing 10 from the heat exchange air inlet 12, and the heat exchanged air is discharged into the room through the air outlet side of the air duct frame 20 and the heat exchange air outlet 14 of the casing 10, thereby realizing refrigeration or heating.

The cross flow fan 40 is installed in the heat exchange duct 222 in a lateral direction for inducing indoor air flow into the cabinet 10 from the heat exchange air flow inlet 12 to exchange heat with the evaporator 30 and finally discharged from the heat exchange air flow outlet 14.

Referring to fig. 2 to 4, the dashed arrows in fig. 2 and 3 represent heat exchange air flow, the dashed arrows represent indoor air, and fig. 4 is a schematic diagram of the positional relationship between the air guide 50 and the two rotating arms 60 in the wall-mounted air conditioning indoor unit 1 according to one embodiment of the present utility model.

In some embodiments, the wall-mounted air conditioner indoor unit 1 may further include an air guide 50. The air guide 50 is formed in an oblong shape, is disposed around the casing 10, has a length direction thereof disposed in a lateral direction of the casing 10, and has a plurality of air flow passages 501 disposed therethrough in a thickness direction thereof and in a width direction, and the air guide 50 is configured to be rotatable about a rotation axis parallel to the length direction thereof between a flow guiding position and a flow guiding position.

Referring to fig. 2, when the air guiding member 50 is at the drainage position, the air guiding member 50 is spaced below the heat exchange air outlet 14, so that a drainage air duct 18 is formed between the wider surface and the casing 10, and the indoor air is further forced to pass through the drainage air duct 18 from back to front by using the pressure difference and is mixed with the heat exchange air flow sent out from the heat exchange air flow outlet 14.

Referring to fig. 3, when the air guide 50 is in the guiding position, the wider face of the air guide 50 faces the heat exchange air flow outlet 14, so that the heat exchange air flow discharged from the heat exchange air flow outlet 14 is guided by the air flow passage 501.

In the present embodiment, the wind guide 50 is connected to the casing 10 through two rotating arms 60, and is rotatable relative to the casing 10 at a drainage position and a diversion position. The driving mode of the air guide 50 may be either manual rotation or motor driving, which is not particularly limited in the present utility model.

When the air guide 50 is at the drainage position, the air guide 50 is spaced below the heat exchange air outlet 14, and a drainage air channel 18 is formed between the wider surface of the air guide and the casing 10. Because the flow rate of the heat exchange air flow at the heat exchange air flow outlet 14 is relatively high, the pressure at the heat exchange air flow outlet 14 and the vicinity thereof is relatively low compared with the room according to the bernoulli effect, so that the drainage duct 18 formed between the heat exchange air flow outlet 14 and the air guide 50 is also at a relatively low pressure, and thus the room air can be sucked into the drainage duct 18 from back to front and then discharged to the vicinity of the heat exchange air flow outlet 14 forward, thereby achieving the mixing of the room air and the heat exchange air flow to increase the air output.

In addition, because the indoor air flow and the heat exchange air flow have a certain temperature difference, the indoor air entering the drainage air duct 18 can also adjust the air outlet temperature on the premise of not affecting the integral refrigeration or heating efficiency. For example, when the indoor unit is in the cooling mode, the indoor air can increase the temperature of the heat exchange air flow, so that the temperature of the heat exchange air flow is soft, and the experience of a user is improved.

The wider surface of the air guide 50 may be substantially parallel to the bottom wall of the casing 10 or may be inclined at a certain angle to the bottom wall of the casing 10, as long as the air guide 18 can be defined, and the present utility model is not limited thereto.

When the air guiding member 50 is at the guiding position, the wider side of the air guiding member 50 faces the heat exchanging air flow outlet 14, and because the air flow channel 501 penetrates through the width direction of the air guiding member 50, when the air guiding member 50 is at the guiding position, the inlet of the air flow channel 501 faces the heat exchanging air flow outlet 14, so that the heat exchanging air flow discharged from the heat exchanging air flow outlet 14 can enter the air flow channel 501, and the air flow channel 501 can be utilized to conduct secondary guiding on the heat exchanging air flow, so as to make up the defect that the air guiding angle of the air guiding plate 16 is limited.

Further, since the airflow passage 501 is arranged in the width direction, which is substantially elongated, the ventilation amount of the airflow passage 501 is large, and therefore, although the heat exchange airflow is scattered by the airflow passage 501, the influence on the wind speed thereof is small, and the supply distance of the heat exchange airflow can be ensured.

It should be noted that, when in the guiding position, the wider side of the air guiding member 50 faces the heat exchange airflow outlet 14, and at this time, the air guiding member 50 may be opposite to the heat exchange airflow outlet 14, or may form a certain inclination angle with the heat exchange airflow outlet 14, so long as the heat exchange airflow can be ensured to enter the airflow channel 501, which is not particularly limited in the present utility model.

In some embodiments, the middle portion of the air guide 50 has a hollow frame penetrating in the thickness direction, and a plurality of grids 510 spaced apart in the width direction of the air guide 50 are disposed in the hollow frame to divide the hollow frame into a plurality of air flow channels 501.

The size and shape of the hollow frame may be designed according to the size and shape of the heat exchange air flow outlet 14. For example, when the heat exchange air flow outlet 14 is rectangular, the hollow frame may be rectangular, so that the heat exchange air flow can enter the air flow channel 501 as much as possible.

The grids 510 are elongated, and the length direction of the grids is consistent with the length direction of the air guide 50, and two ends of each grid 510 are respectively fixed to two lateral sides of the hollow frame. In some particular embodiments, the grille 510 may also be integrally formed on the air guide 50.

Further, a plurality of reinforcing ribs may be provided between adjacent two of the grids 510 to improve mechanical strength of the grids 510 and prevent deformation.

In order to clearly describe the shape of the grill 510, when the air guide 50 is at the drainage position, the width direction of the air guide 50 from back to front is referred to as a first direction, and the thickness direction of the air guide 50 from top to bottom is referred to as a second direction.

Referring to fig. 5, fig. 5 is a cross-sectional view of an air guide 50 according to one embodiment of the present utility model. In some embodiments, at least a portion of the plurality of grids 510 are disposed adjacent to each other in the plurality of grids 520, that is, all of the plurality of grids 510 may be the first grid 520, or may be partially the first grid 520, but when partially the first grid 520, the number of the first grids 520 should be two or more, and disposed adjacent to each other in order to define the outlet flow channel 501.

Further, each first grid 520 may include a first plate segment 522, a second plate segment 524, and a third plate segment 526. The first plate segment 522 extends in a first direction, the beginning of the second plate segment 524 is formed at the end of the first plate segment 522 and extends in a second direction, and the beginning of the third plate segment 526 is formed at the end of the second plate segment 524 and extends obliquely in the first and second directions.

Taking two adjacent first grids 520 as an example, in the first direction, the first plate sections 522 of the front first grids 520 extend backward, and the third plate sections 526 of the rear first grids 520 extend forward, that is, the two adjacent first grids 520 form the bent airflow channel 501, so that the first plate sections 522 of the front first grids 520 and the third plate sections 526 of the rear first grids 520 can shield the airflow channel 501 when seen in the second direction, and thus when in the drainage position, the indoor air passing through the drainage duct 18 from backward forward passes through the airflow channel 501 with smaller flow, and the air leakage of the air guide 50 is reduced.

With reference to fig. 3, further taking this as an example, when the air guiding member 50 is at the guiding position, the wider surface of the air guiding member 50 faces the heat exchange airflow outlet 14, that is, the inlet of the airflow channel 501 faces the heat exchange airflow outlet 14, so that the influence on the entering of the heat exchange airflow into the airflow channel 501 caused by the arrangement of the first grille 520 in the form of turning is less.

In addition, in connection with fig. 3, since the third plate section 526 has already exhibited a forward tilting tendency when the air guide 50 is in the guiding position, when the air guide 50 is rotated from the guiding position to the guiding position, the third plate section 526 is likely to be directed forward and even forward upward (as shown in fig. 3), so that the heat exchange air flow can be directed upward by the air flow channel 501, avoiding the direct blowing of the user.

Referring to fig. 6, fig. 6 is a cross-sectional view of an air guide 50 according to another embodiment of the present utility model. In other embodiments, at least a portion of the plurality of gratings 510 are a plurality of adjacently disposed second gratings 530, each of the second gratings 530 having a flat plate shape and extending obliquely in the first direction and the second direction.

Similar to the above embodiment, the second grille 530 can also reduce the air leakage of the air guide 50, reduce the influence of the heat exchange air flow entering the air flow channel 501 when the air guide is at the diversion position, and guide the heat exchange air flow upwards by using the air flow channel 501, so as to avoid the technical effects of direct blowing of users, and the like, and will not be described again.

Referring to fig. 2-5, in some embodiments, the wider face of the wind guide 50 is contoured as a convex circular arc. Because the wider surface of the air guide 50 is equivalent to one wall surface of the air guide 18, when the outline of the wider surface of the air guide 50 is set to be an outer convex arc surface, indoor air can flow along the wider surface of the air guide 50 under the coanda effect, so that the indoor air and the heat exchange air flow are mixed.

In connection with fig. 2 and 3, as the bottom wall of the casing 10 also participates in forming the drainage duct 18, the bottom wall of the casing 10 may also be provided as an outer convex arc surface so that the indoor air is mixed with the heat exchange air flow.

In some embodiments, the wall-mounted indoor unit 1 may further include two rotating arms 60, where the two rotating arms 60 are respectively located at two ends of the length direction of the air guiding member 50, and a first end of each rotating arm 60 is rotatably connected to a side wall of the casing 10, and a second end is connected to an end of the air guiding member 50, so that the air guiding member 50 can rotate relative to the casing 10.

Referring to fig. 1, in some specific embodiments, two side walls of the casing 10 may be provided with a turntable 70, and the centers of the two turntables 70 are located on the same horizontal rotation axis, each turntable 70 can rotate in the side wall where the turntable 70 is located, a first end of the rotating arm 60 is fixedly mounted on the turntable 70, and a second end of the rotating arm 60 is mounted on the air guide 50, so as to implement rotation of the air guide 50 relative to the casing 10.

In some specific embodiments, the second end of the swivel arm 60 may be fixedly coupled to the wind guide 50. In other embodiments, the second end of each swivel arm 60 may be rotatably coupled to the wind guide 50 such that the wind guide 50 itself can be adjusted in attitude by rotation to achieve fine adjustment.

Referring to fig. 7 and 8, fig. 7 is an exploded view of part of components in the wall-mounted air conditioning indoor unit 1 according to an embodiment of the present utility model, and fig. 8 is a schematic view of the installation relationship of the air guide 50 and the swivel arm 60 in the wall-mounted air conditioning indoor unit 1 according to an embodiment of the present utility model.

Further, the second end of each swivel arm 60 has a connecting section 62 extending along the length of the wind guide 50. The wind guide 50 has mounting grooves 503 formed at both ends in the longitudinal direction thereof, and the side wall of the wind guide 50 has a rotation hole 504 communicating with the mounting grooves 503.

The wall-mounted air conditioner indoor unit 1 may further comprise two sleeves 80 and two rotary connectors 90. Each sleeve 80 has a fitting hole 82, and two sleeves 80 are respectively fixed in two mounting grooves 503, and the fitting holes 82 are abutted with the rotating holes 504. Each rotary joint member 90 has an inner race 91 and an outer race 92, and the rotary joint member 90 extends into the mounting slot 503 through the rotary hole 504 such that the outer race 92 thereof is rotatably coupled to the mounting hole 82 and the inner race 91 is journaled to the coupling section 62.

When the inner ring 91 of the rotary connector 90 is in hub connection with the connecting section 62, the form may be various, for example, the inner ring 91 of the rotary connector 90 and the connecting section 62 may be set to be force-closed (i.e. interference fit), or the inner ring 91 of the rotary connector 90 and the connecting section 62 may be set to be form-closed, for example, form-fit connection (as shown in fig. 7, the D-shaped shaft is matched with the D-shaped hole). The above-mentioned manner can prevent the rotation of the rotary connecting member 90 and the connecting section 62, and those skilled in the art can also substitute other structures, which are not shown here.

Further, a plurality of claws 93 are formed at the inner end of the rotary connector 90, and the claws 93 are engaged with the end of the sleeve 80 away from the rotary hole 504 to prevent the rotary connector 90 from sliding out of the assembly hole 82.

Further, a plurality of pre-tightening flanges 94 are formed on the outer ring 92 of the rotating connector 90 along the circumferential direction thereof, and the plurality of pre-tightening flanges 94 abut against the inner wall of the assembly hole 82 to pre-tighten the rotating connector 90 and the sleeve 80, so as to prevent the rotating connector 90 from shaking in the sleeve 80.

Further, at least one of the pre-tightening flanges 94 is raised to form a hover projection 95, the sleeve 80 being provided with a plurality of hover apertures 84 along its circumference, the hover projection 95 extending into the hover aperture 84 to define a circumferential rotational degree of freedom of the rotational coupling 90. That is, hover aperture 84, when mated with hover projection 95, may cause air guide 50 to hover at the current gesture.

Further, the inner wall of the rotation hole 504 near the inner side protrudes to form an abutment ring 505, and the outer end of the rotation connecting piece 90 abuts against the abutment ring 505 to limit the axial freedom of the rotation connecting piece 90, so as to prevent the rotation connecting piece 90 from extending into the installation groove 503 from the rotation hole 504.

Further, the inner side of the fitting hole 82 is also formed with an abutment rib 86 protruding to limit the axial freedom of the connection section 62, preventing the connection section 62 from being excessively protruded into the rotation hole 504 to be protruded into the fitting hole 82.
