Description
Technical Field
The invention relates to the technical field of air conditioning, in particular to a wall-mounted air conditioner indoor unit.
Background
When the air conditioner operates in a refrigeration mode, the cold air tends to sink due to relatively high density; when the air conditioner operates in a heating mode, the hot air density is relatively small and tends to rise. Therefore, the air conditioner needs to blow cold air upwards as much as possible during refrigeration, and needs to blow hot air towards the ground as much as possible during heating, so that the cold air or the hot air is diffused more uniformly in the indoor space, the refrigeration and heating speed is higher, the refrigeration and heating effects are better, and the cold and hot feeling of a user is better.
The existing various wall-mounted air-conditioning indoor units are generally only provided with an air outlet which is opened towards the front lower part, and various air guide structures such as an air guide plate, a swing vane and the like are utilized to guide the air outlet direction of air supply airflow so as to realize upward air blowing or downward air blowing. However, the current wind guiding structures have limited wind guiding angles, and only can supply wind obliquely upwards or obliquely downwards, and cold wind or hot wind still cannot reach a roof or a floor area, so that the cooling or heating effect is influenced.
Disclosure of Invention
The object of the present invention is to provide a wall-mounted air conditioning indoor unit that overcomes, or at least partially solves, the above-mentioned problems.
The invention aims to strengthen the down-blowing effect of the wall-mounted air conditioner indoor unit and enable the down-blowing direction to be closer to the vertical direction.
In particular, the present invention provides a wall-mounted air conditioning indoor unit, comprising:
a housing provided with an air outlet opening forward and downward;
the air duct comprises a front air duct wall and a rear air duct wall which are arranged at intervals in the front-rear direction, and the outlet ends of the front air duct wall and the rear air duct wall are respectively connected with the upper end and the lower end of the air outlet so as to guide the airflow of the shell to the air outlet; and is
The rear air duct wall comprises a main body section and a turning section, and the turning section is connected with the air outlet end of the main body section and bends and extends downwards compared with the main body section so that the air flow can flow downwards along the turning section after flowing out of the main body section; and is provided with
The turning section is in a convex bending shape.
Optionally, the turning section is an arc shape protruding outwards, and an axis of the arc shape is parallel to the transverse direction of the air outlet.
Optionally, the main body section is integrally of a concave-back curved shape, a portion of the main body section, which is connected with the turning section, is of a concave arc shape, and an axis of the arc-shaped portion is parallel to a transverse direction of the air outlet.
Optionally, the ratio of the diameter of the arcuate portion where the main body section and the turning section meet to the diameter of the turning section is between 2 and 3.
Optionally, the air inlet end of the turning section is tangent to the air outlet end of the main body section.
Optionally, an included angle between the air outlet direction of the turning section and the air outlet direction of the main body section is between 45 ° and 55 °.
Optionally, the turning section is connected with the bottom wall of the shell through a convex protruding section.
Optionally, the front air duct wall comprises a first section extending from the front upper part to the rear lower part and a second section extending from the lower end of the first section to the upper end of the air outlet; and is
The second section is in a convex arc shape, and the axis of the second section is parallel to the transverse direction of the air outlet.
Optionally, an included angle between the air outlet direction and the air inlet direction of the second section is less than 45 °.
Optionally, the wall-mounted air conditioner indoor unit further includes an air deflector, and the air deflector includes:
the air deflector body is rotatably arranged at the air outlet;
the multilayer inner air deflector is arranged on the inner side of the air deflector body and is sequentially fixed on the air deflector body at intervals along the direction far away from the inner surface of the air deflector body so as to guide air flow together with the air deflector body.
In the wall-mounted air conditioner indoor unit, the air duct comprises the front air duct wall and the rear air duct wall which are arranged at intervals in the front-rear direction, so that the rear air duct wall comprises the main body section and the turning section, and the turning section is connected with the air outlet end of the main body section and is bent and extended downwards compared with the main body section, so that airflow flows out of the main body section and then flows downwards along the turning section in a bent mode. According to the coanda effect, when there is surface friction (also called fluid viscosity) between a fluid and the surface of an object over which it flows, the fluid will follow the surface of the object as long as the curvature is not large. Therefore, although the direction of the turning section is turned downwards at an angle compared with the main body section, the airflow will continue to flow along the surface of the turning section. Therefore, the air outlet direction of the airflow has a downward turning, so that the airflow is closer to a vertical downward direction, and the airflow is more beneficial to directly reaching the ground. Especially when the air conditioner heats, can realize warm foot experience through blowing downwards.
Further, the wall-mounted air conditioner indoor unit of the invention particularly limits the shape of the turning section, the shape of the main body section, and important dimensions and angle parameters, so as to realize the optimal 'wind direction turning' effect. Specifically, even if the bending angle of the turning section is larger, the wind direction turning angle is larger and is closer to the vertical direction; meanwhile, a strong enough wall attachment effect is ensured, so that the problem that the airflow cannot be well attached to the surface of the turning section due to too large bending angle of the turning section is avoided, and the total amount of the airflow finally completing the turning is too small.
Specifically, the turning section is set to be convex curved (for example, arc-shaped), so that when the airflow flows along the surface of the convex curved turning section, the turning angle is continuously increased, and the final air outlet angle is closer to the vertical downward direction. In addition, in order to avoid that the air flow is easy to separate from the surface of the turning section due to overlarge turning angle and the air flow finally participating in the turning is reduced, the invention also particularly limits the included angle between the air outlet direction of the turning section and the air outlet direction of the main body section between 45 degrees and 55 degrees (the angle is the angle for turning the air flow due to the added turning section), so that the air flow not only has a better turning effect, but also ensures that the air flow has good wall attaching effect and the air flow participating in the wall attaching (turning) is more. In a word, the invention gives consideration to the two aspects of angle and air quantity of the wind direction turning.
Furthermore, in the wall-mounted air conditioner indoor unit, the turning section is connected with the bottom wall of the shell through the convex protruding section, so that the air supply airflow flows out of the turning section and then flows out of the air outlet along the protruding section by virtue of the wall attachment effect, and the air supply airflow further turns downwards after flowing through the protruding section, so that the air outlet direction is closer to the vertical direction.
Furthermore, in the wall-mounted air conditioner indoor unit, the front air duct wall comprises a first section extending from the front upper part to the rear lower part and a second section extending from the lower end of the first section to the upper end of the air outlet forward, and the second section is in an outward convex arc shape, so that the airflow on the surface of the front air duct wall is gradually raised along the second section, the raising angle of the supplied airflow is larger, and the raising angle of the airflow is favorably improved when the air conditioner performs refrigeration and upward blowing.

The embodiment of the invention provides a wall-mounted air conditioner indoor unit. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.
As shown in fig. 1 to 3, a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and an air duct 20.
Wherein, the housing 10 is provided with an air outlet 12 opening towards the front lower part. The casing 10 defines an accommodation space for accommodating components of the wall-mounted air conditioning indoor unit. The outlet 12 may be opened at a lower portion of the front side of the housing 10 so as to be open toward the front lower side. The outlet 12 is used to discharge the airflow in the housing 10 to the indoor environment to condition the indoor air. The discharged air flow is referred to as air flow which is acted on by a fan in the housing 10 to accelerate the air flow through the outlet 12 for conditioning the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, and fresh air in a fresh air mode, etc. The housing 10 may be a long strip with a length direction horizontally arranged, and the outlet 12 may be a long strip with a length direction parallel to the length direction of the housing 10.
The duct 20 includes a front duct wall 200 and a rear duct wall 100 spaced apart from each other in a front-rear direction, and outlet ends of the front duct wall 200 and the rear duct wall 100 are respectively connected to an upper end and a lower end of the air outlet 12, so as to guide the air flow of the housing 10 to the air outlet 12. The rear duct wall 100 includes a main body section 110 and a turning section 120(BC section), and the turning section 120 is connected to the air outlet end of the main body section 110 and bends downward relative to the main body section 110, so that the airflow flows out of the main body section 110 and then bends downward along the turning section 120.
In fig. 2, the dotted arrows near the rear duct wall 100 indicate the airflow direction when the turning section 120 is not provided, and the solid arrows indicate the airflow direction after the turning section 120 is provided.
The inventor has recognized that a conventional wall-mounted air conditioning indoor unit is limited to an internal fan, a heat exchanger, and the like, and an air outlet is generally opened in a lower front portion of a casing and opened forward and downward. In such a solution, the air deflector at the air outlet is not convenient to guide the outlet airflow in a vertically upward or near vertically upward direction due to the obstruction of the front part of the housing. Therefore, the uplift angle of the air outlet flow is very limited, and the uplift distance of the air flow is difficult to lift.
In the embodiment of the present invention, since the main body section 110 and the turning section 120 are disposed on the rear air duct wall 100, the air flow flows downward along the turning section 120 after flowing out from the main body section 110. According to the coanda effect (also called wall attachment effect) of a fluid, when there is surface friction (also called fluid viscosity) between the fluid and the surface of an object over which the fluid flows, the fluid will follow the surface of the object as long as the curvature is not large. Therefore, in this embodiment, although the direction of the turning section 120 is turned downward at an angle compared to the main body section 110, the airflow will continue to flow along the surface of the turning section 120 due to the viscosity. Therefore, the air outlet direction of the airflow has a downward turning, so that the airflow is closer to a vertical downward direction, and the airflow is more beneficial to directly reaching the ground. Especially when the air conditioner heats, can realize warm foot experience through blowing downwards.
In particular, in the embodiment of the present invention, as shown in fig. 2 and 3, the shape of the turning section 120, the shape of the main body section 110, and important dimensions and angle parameters are particularly limited so as to achieve an optimal "wind direction turning" effect. That is, even if the bending angle of the turning section 120 is made larger, the wind direction turning angle is made larger and closer to the vertical downward direction; meanwhile, a strong enough wall attachment effect is ensured, so that the problem that the airflow cannot be well attached to the surface of the turning section 120 due to a too large bending angle of the turning section 120 and the total amount of the airflow finally completing the turning is too small is avoided.
In the embodiment of the present invention, the turning section 120 is in the convex curved shape, so that the airflow continuously turns downward when flowing along the surface of the convex curved turning section 120, and the final air outlet angle is closer to the vertical downward direction. In some specific configurations, the turning section 120 may be a convex arc, and the axis of the arc is parallel to the transverse direction of the air outlet. The lateral direction of the outlet port 12 refers to the lateral direction of the housing 10, that is, the direction perpendicular to the paper surface in each of fig. 1 to 3.
As shown in fig. 2 and 3, the main body section 110 may be a concave-back curved shape, and the portion of the main body section 110 connected to the turning section 120 is a concave arc shape, and the axis of the arc portion is parallel to the transverse direction of the air outlet 12, so that the transition between the main body section 110 and the turning section 120 is more gradual. The rest of the main body segment 110 may also be formed by an arc or a plurality of arcs connected together.
Further, the ratio of the diameter of the arc-shaped portion where the main body section 110 and the turning section 120 meet to the diameter of the turning section 120 is between 2 and 3, inclusive, preferably between 1.5 and 2.5, so that the airflow is more stable in the turning direction from the main body section 110 to the turning section 120, and the unstable airflow caused by too large or too small difference in diameter is avoided.
Other fields in some existing application structures using the "coanda effect", the surface of the object is often arranged to be flat and to have a large angular turn in order to obtain a larger angular turn of the fluid. The inventor of the present invention has found that if the turning section 120 is arranged to be a plane, there is a certain coanda effect, but when the angle of the turning section 120 is larger, the airflow is easier to separate from the surface, and the airflow finally bent and turned becomes less.
Therefore, in the embodiment of the present invention, in order to avoid that the airflow is easily separated from the surface of the turning section due to an excessively large turning angle and the airflow finally participating in the turning becomes less, the embodiment of the present invention particularly defines the included angle α between the air outlet direction of the turning section 120 (the tangential direction of the point C) and the air outlet direction of the main body section 110 (the tangential direction of the point B) between 45 ° and 55 ° (the angle is the angle for turning the airflow due to the addition of the turning section 120), so that the airflow has a better turning effect and also ensures a good wall attachment effect, and the total amount of the airflow participating in the wall attachment (turning) is larger. In summary, the embodiments of the present invention make the "wind direction turning" compatible with both turning angle and total wind volume.
In some embodiments of the present invention, as shown in fig. 2, the air inlet end of the turning section 120 can be tangent to the air outlet end of the main body section 110, so that the transition between the two is more gradual, which is beneficial to enhancing the wall attachment effect of the airflow.
In some embodiments of the present invention, as shown in fig. 2, the turning section 120(BC section) and the bottom wall 101 of the casing 10 are connected by a convex protruding section 130(CD section), so that after the airflow flows out of the turning section 120(BC section), at least a portion of the airflow can continue to turn downward along the surface of the protruding section 130, so as to increase the downward blowing angle of the airflow, and the downward blowing direction is closer to the vertical direction.
In some embodiments of the present invention, as shown in fig. 1 to 3, the front air duct wall 200 may include a first section 210 (i.e., an EF section) extending from the front upper side to the rear lower side, and a second section 220 (i.e., an FG section) extending from the lower end of the first section 210 to the upper end of the air outlet 12 (including extending forward, extending upward forward, or extending downward forward). Moreover, the second section 220 is a convex arc, and the axis thereof is parallel to the transverse direction of the outlet 12, i.e. parallel to the paper surface.
In the embodiment of the invention, the second section 220 is in the shape of the convex arc, so that the airflow on the surface of the front air duct wall 200 is gradually raised along the second section 220 by virtue of the coanda effect, the raising angle of the supplied airflow is larger, and the raising angle of the airflow is favorably improved and the raising distance is increased when the air conditioner performs refrigeration and upward blowing.
Furthermore, the included angle θ between the air outlet direction and the air inlet direction of the second section 220 is smaller than 45 °, so as to avoid excessive separation of the air flow from the surface of the second section 220 due to an excessively large turning angle, and to reduce the air flow finally bent and turned.
The wall-mounted air conditioner indoor unit of the embodiment of the invention can be an indoor part of a split wall-mounted room air conditioner which utilizes a vapor compression refrigeration cycle system to refrigerate/heat. As shown in fig. 1, a heat exchanger 30 and a fan 40 are provided inside the casing 10. The heat exchanger 30 and the throttle device are connected to a compressor, a condenser and other refrigeration components disposed in the outdoor unit casing 10 through pipes, thereby forming a vapor compression refrigeration cycle system.
Under the action of the fan 40, the indoor air enters the inside of the housing 10 through the air inlet 11 at the top of the housing 10, and after completing the forced convection heat exchange with the heat exchanger 30, forms heat exchange air, and then blows toward the air outlet 12 under the guidance of the air duct 20.
The fan 40 is preferably a cross flow fan having an axis parallel to the length of the housing 10, and is disposed at the inlet of the air duct 20. The heat exchanger 30 may be a three-stage heat exchanger that surrounds the fan 40 in front of and above the fan 40 to make its heat exchange efficiency higher.
In some embodiments, as shown in fig. 1, the wall-mounted air conditioning indoor unit may further include a wind deflector 60 for guiding the wind outlet 12 in the upward and downward wind direction. The above-mentioned up-blowing/down-blowing effect can be enhanced by the cooperation of the air duct 20 and the air deflector 60. That is, when the air deflector 60 guides the air flow downward, the rear duct wall 100 can perform an auxiliary downward blowing function, which facilitates the downward blowing of the air flow. When the air deflector 60 guides the airflow upward, the front duct wall 200 can perform an auxiliary upward blowing function, which is beneficial to the upward blowing of the airflow.
The air deflection 60 may include an air deflection body 61 and multiple layers of internal air deflection 62, 63. The air deflector body 61 is rotatably disposed at the air outlet 12 (around the y-axis), the multiple layers of inner air deflectors 62, 63 are disposed inside the air deflector body 61, and the multiple layers of inner air deflectors 62, 63 are sequentially fixed to the air deflector body 61 at intervals along a direction away from the inner surface of the air deflector body 61, so as to guide the air flow together with the air deflector body 61.
Specifically, the air guiding plate 60 may further include at least one connecting portion for connecting and fixing the air guiding plate body 61 and the multiple layers of internal air guiding plates 62 and 63.
The multilayer inner air deflectors 62 and 63 and the air deflector body 61 are arranged at intervals, when the air deflector body 61 rotates to a certain position, the air supply airflow can be guided by the air deflector body 61, and can enter the air deflector body 61 and the adjacent inner air deflectors 62 and 63, and can enter the interval between the air deflector body 61 and the adjacent inner air deflectors 62 and 63 and the interval between the adjacent two inner air deflectors 62 and 63, so that the air supply airflow can be guided by the multilayer inner air deflectors 62 and 63, the multi-layer guiding of the air supply airflow is realized, the air supply airflow direction discharged from the air outlet 12 is uniform, the air supply airflow is combed more smoothly, and the comfort level of a user is further improved.
In some embodiments, as shown in fig. 1, the number of the inner wind deflectors is two, and the two inner wind deflectors 62 and 63 are respectively arranged on the inner side of the wind deflector body 61 at intervals in sequence. In the flowing direction of the blowing air flow, the inner air deflector 63 which is farthest away from the air deflector body 61 can guide at least a part of the blowing air flow by using the inner surface thereof, the rest of the blowing air flow can sequentially enter the gap between the two inner air deflectors 62 and 63 and the gap between the inner air deflectors 62 and 63 which are positioned at the back and the air deflector body 61, and the rest of the blowing air flow is guided again by using the inner surfaces of the inner air deflectors 62 and 63 and the air deflector body 61, so that the blowing air flow in a certain direction is more layered.
In addition, the inventor finds out through simulation and experiment that: the direction and the wind speed of the air supply airflow which is led out together by the air deflector body 61 and the multiple layers of inner air deflectors 62 and 63 (the air supply airflow is converged together after being separated from the air deflector 60) are more stable, the air gathering effect is better, the far-end wind speed of the air outlet is increased during refrigeration, the air supply distance is longer, the air outlet guide is smoother during heating, the air volume loss is small, the wind resistance loss increased by adding the multiple inner air deflectors 62 and 63 can be completely offset, and the air outlet efficiency is even better than that of a single guide plate, so the wall-mounted air conditioner indoor unit of the embodiment obtains unexpected technical effects.
It should be noted that the above examples are only for describing the technical solution of the present embodiment more clearly, and the specific number of the inner wind deflectors 62 and 63 is not limited, and those skilled in the art should understand that the number of the inner wind deflectors 62 and 63 in the present embodiment may also be three, four or more, but not all.
In the prior art, in order to adjust the air supply direction of an indoor unit of an air conditioner, an air deflector capable of swinging up and down is generally arranged at an air outlet. However, this adjustment has certain disadvantages. The air deflector can only guide the air flow close to the inner surface of the air deflector, but cannot guide the air flow far away from the inner surface of the air deflector, so that the air outlet air flow discharged from the air outlet is disordered, the air flow is not combed smoothly, and the experience of a user is reduced.
In order to overcome the defects of the prior art, in the wall-mounted air conditioner indoor unit of the embodiment, the inner air deflectors 62 and 63 which are fixed on the air deflector body 61 at intervals in multiple layers are additionally arranged on the inner side of the air deflector body 61, and the air flow blown out in a certain direction is enabled to be layered by utilizing the inner surfaces of the inner air deflectors 62 and 63 and the air deflector body 61 to guide the air flow, and the air flow is enabled to be more guided, the air flow is more smoothly combed, the overall direction and the air speed are more stable, so that the air gathering effect of the air flow is enabled to be better, the air outlet efficiency is higher, and the experience of users is improved.
In some embodiments, an orthographic projection of the inner air deflector 62 adjacent to the air deflector body 61 onto the air deflector body 61 falls on the air deflector body 61. And in the direction far away from the inner surface of the air deflector body 61, the orthographic projection of the rest inner air deflectors to the upper layer falls on the inner air deflector of the upper layer.
In the embodiment, the inner air deflector 62 adjacent to the air deflector body 61 may be set to have the same size as the air deflector body 61, or smaller than the width of the air deflector body 61, and is opposite to the air deflector body 61, so that the air deflector body 61 can wrap the inner air deflectors 62, 63.
Similarly, the other inner air guiding plates can be set to have the same size as the inner air guiding plate on the previous layer or smaller than the width of the air guiding plate body 61, and are opposite to the inner air guiding plate on the previous layer, so that the inner air guiding plate on the previous layer can wrap the inner air guiding plate on the next layer.
After the above limitation, when the air deflector 60 is used for guiding air, the inner air deflector or the air deflector body 61 located at the outer layer can receive the air supply flow leaking from the inner air deflector at the inner layer, so as to ensure that the air supply flow can be guided by multiple layers and finally discharged out of the air outlet 12.
In some embodiments, the same side ends of the air deflector body 61 and the multi-layer inner air deflectors 62 and 63 can also be configured to be on the same plane.
One ends of the air deflector body 61 and the multiple layers of internal air deflectors 62 and 63 are positioned on the same plane, and the other ends of the air deflector body 61 and the multiple layers of internal air deflectors 62 and 63 are positioned on the same plane, so that the appearance of the air deflector 60 is more attractive.
In some embodiments, the width of the deflector body 61 is greater than the width of the inner deflector 62 adjacent thereto, and the width of the multiple layers of inner deflectors 62, 63 decreases in a direction away from the inner surface of the deflector body 61.
That is, for the inner air deflector of the inner layer, the two ends of the inner air deflector of the outer layer are provided with the dislocation sections which are expanded to form the inner air deflector of the inner layer, and the dislocation sections can be used for not only receiving the air supply flow leaked from the inner air deflector of the inner layer, but also facilitating the air supply flow to enter the gap between the two inner air deflectors, and finally ensuring the air supply flow to enter the gap between every two adjacent inner air deflectors.
Similarly, for the inner air deflector 62 adjacent to the air deflector body 61, the width of the air deflector body 61 is greater than that of the inner air deflector 62 adjacent to the air deflector body 61, and the two ends of the air deflector body 61 have offset sections extending out of the inner air deflector 62 adjacent to the air deflector body, and the offset sections are used for receiving the air supply flow leaking from the inner air deflector 62.
Further, the inner surfaces of the air guide plate body 61 and the inner air guide plates 62 and 63 may be arranged in concentric circular arc surfaces.
In fluid mechanics, according to the principle of the coanda effect, when a fluid has a tendency to flow along a convex object surface instead of a normal flow direction, the fluid will flow along the object surface when there is surface friction between the fluid and the object surface over which it flows, as long as the curvature is not large.
Therefore, the inner side surfaces of the air deflector body 61 and the inner air deflectors 62 and 63 can be configured to be concentric circular arc surfaces, so that the air flow flowing through the inner surfaces of the air deflector body 61 and the inner air deflectors 62 and 63 can be better absorbed, and the guiding effect is better.
Further, the ratio of the distance between the air deflection body 61 and the adjacent inner air deflection plates 62, 63 to the arc length of the inner surface of the air deflection body 61 may also be configured to be between 1/5 and 1/3, such as 1/5, 1/4 or 1/3.
In the direction far away from the inner surface of the air deflector body 61, the ratio of the distance between each inner air deflector 62, 63 and the next adjacent inner air deflector 62, 63 to the arc length of the inner air deflector 62, 63 is between 1/5 and 1/3, such as 1/5, 1/4 or 1/3.
Preferably, the arc length ratio between the inner surface of the main body 61 and the adjacent inner deflector 62, 63 is the same as the arc length ratio between the inner surface of the inner deflector 62, 63 and the next inner deflector 62, 63.
For the air deflector body 61 and the inner air deflectors 62 and 63, the longer the arc length is, the stronger the air guiding capability is, so that the larger the corresponding distance between the inner surfaces of the air deflector body 61 or the inner air deflectors 62 and 63 with longer arc length is, the larger the flow rate of the supplied air flow is, and the more reasonably the supplied air flow is distributed to the air deflector body 61 and the inner air deflectors 62 and 63, so as to guide the supplied air flow more and enable the supplied air flow to be combed more smoothly.
Of course, after the technical solution of the present embodiment is known by those skilled in the art, the inner surfaces of the air guiding plate body 61 and the multiple layers of inner air guiding plates 62 and 63 may also be set to be a plane. Compared with the above-described embodiment, the flat plate-shaped air deflector body 61 and the multi-layer inner air deflectors 62 and 63 can basically guide the blowing air flow more, but the technical effect obtained by the arc-shaped inner surface is better.

As shown in fig. 4, the air deflector 60 can be rotated to an upward blowing position where the inner surfaces of the air deflector body 61 and the inner air deflectors 62 and 63 face upward, so as to guide the blowing air flow forward or forward and upward. The up-blow position is particularly suited for the cooling mode.
As shown in fig. 5, the air deflector 60 can be rotated to a downward blowing position where the inner surfaces of the air deflector body 61 and the inner air deflectors 62 and 63 face rearward, so as to guide the air flow downward. The down-blowing position is particularly suitable for heating mode.
As shown in fig. 6, the air deflector 60 can be rotated to a position where the air deflector body 61 is substantially parallel to the front duct wall 200 and the rear duct wall 100, so as to minimize the resistance to the air flow and realize the maximum air volume blowing.
It should be noted that the above examples are only for describing the operation principle of the air deflector 60 of the present embodiment more clearly, and are not intended to limit what temperature adjusting mode (heating or cooling) the wall-mounted air conditioning indoor unit is necessarily in when the air deflector 60 is located. The user can adjust the working position of the air guiding plate 60 at will according to the actual situation, for example, the air guiding plate 60 is adjusted to the upper blowing position in the heating mode, and the air guiding plate 60 is adjusted to the lower blowing position in the cooling mode, which is not described herein again.
In some embodiments, the wall-mounted air conditioning indoor unit further includes an outer air deflector 50, and the outer air deflector 50 is movably disposed at the outlet 12 for opening and closing the outlet 12. Specifically, the outer wind deflector 50 may be rotatably mounted to the housing 10 with the rotation axis x at the rear duct wall 100 so as to move to a position directly below the housing 10 to completely open the wind outlet 12.
