The utility model provides an air deflector for a wall-mounted air conditioner indoor unit and a wall-mounted air conditioner indoor unit with the same. 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.

FIG. 1 is a schematic cross-sectional view of a wind deflector according to an embodiment of the utility model; fig. 2 is a schematic structural view of a wall-mounted air conditioner indoor unit having the air guide plate of fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 after the air guide plate is rotated to another angle.

As shown in fig. 1 to 3, the wall-mounted air conditioning indoor unit includes a casing 10 and a louver 50, and the casing 10 may be elongated in a longitudinal direction (a direction perpendicular to the paper surface of fig. 1) and horizontally disposed. The casing 10 defines an accommodation space for accommodating components of a wall-mounted air conditioning indoor unit. The housing 10 is provided with an air outlet 12 for discharging air flow therein, wherein the discharged air flow is acted by a fan in the housing 10 to accelerate the air flow flowing through the air outlet 12 for adjusting the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, fresh air flow in a fresh air mode, and the like. The air guiding plate 50 is rotatably mounted at the air outlet 12 around a rotation axis x parallel to the length direction thereof for guiding the air outlet direction of the air outlet 12. The outlet 12 and the air deflector 50 may be long strips with the length direction parallel to the length direction of the casing 10.

The wall-mounted air conditioner indoor unit may be an indoor part of a split wall-mounted type room air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. As shown in fig. 2, the inside of the case 10 is provided with a heat exchanger 30 and a fan 40. The heat exchanger 30 and the throttling device are connected with a compressor, a condenser and other refrigeration elements arranged in the air conditioning chamber outer shell 10 through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the inside of the casing 10 through the air inlet 11 at the top of the casing 10, and after the forced convection heat exchange with the heat exchanger 30 is completed, heat exchange air is formed and enters 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.

The wall-mounted type air conditioning indoor unit further includes a front air duct wall 200 and a rear air duct wall 100. The front duct wall 200 and the rear duct wall 100 are spaced forward and rearward to define the aforementioned duct 20. The outlet ends of the front duct wall 200 and the rear duct wall 100 are respectively connected to two ends of the air outlet 12, so that the air flow supplied from the air duct 20 flows to the air outlet 12. The front portion of the front duct wall 200 may be provided with an inner concave section 210 to give way to the air guide plate 50, thereby preventing the air guide plate 50 from interfering with the front duct wall 200 when rotating. Due to the concave section 210 of the front duct wall 200, the air deflector 50 can be designed to be wider, so that it can guide the airflow more strongly. Specifically, the concave section 210 may be a circular arc whose axis coincides with the rotation axis of the air deflector 50.

Referring to fig. 1, two edges of the air guiding plate 50 in the width direction are a first edge (a edge) and a second edge (G edge), and two air guiding surfaces of the air guiding plate 50 are a first air guiding surface 51 and a second air guiding surface 52, respectively. In the extending direction from the first side (side a) to the second side (side G), the first air guide surface 51 is formed with an inward concave section AE and an outward convex section EG in this order, and the second air guide surface 52 is formed with an outward convex section AF and an inward concave section FG in this order, so that the air guide plate 50 is formed into a wave shape as a whole. Of course, the concave section AE and the convex section EG are smoothly connected, and the convex section AF and the concave section FG are also smoothly connected.

In the embodiment of the present invention, the air guiding plate 50 is mounted on the casing 10 in the first posture to have an air guiding position in which the first side (side a) faces forward and the first air guiding surface 51 faces upward, please refer to fig. 2.

When the air deflector 50 is in the front wind guiding state shown in fig. 2, the front half (AEF) of the air deflector 50 is gradually raised due to the wave shape, so that the air flow has a good raising effect. The air supply mode can be adopted when the air conditioner is used for refrigerating, so that cold air is upwards guided by the first air guide surface 51, the air supply distance of the cold air is longer, and the cold air is downwards scattered after reaching the highest point, and a bathing type refrigerating effect is formed. The rear half section (EGF) of the air deflector 50 is bent downward, which is also beneficial to guiding the air flow to the upper side of the air deflector 50 and receiving the upward guiding of the first air guiding surface 51. When the air deflector 50 is in the downward air guiding state shown in fig. 3, the first air guiding surface 51 guides the air flow to blow out downward, so that the air flow outlet direction is closer to or reaches the vertical downward direction, and the air flow reaches the ground more, thereby realizing a carpet type sinking air supply effect. The air conditioner can adopt a sinking air supply mode during heating.

Through simulation and experimental verification of the inventor, compared with the conventional flat-plate-shaped or single-arc-shaped air deflector 50, when the air current flows through the wavy air deflector 50, the air deflector 50 can be tightly wrapped, so that the risk of surface condensation of the air deflector 50 is reduced. Compared with the conventional flat-plate or single-arc air deflector 50, the wavy air deflector 50 provided by the embodiment of the utility model has the advantages that the air flow loss is smaller, the air speed is higher after the air flow is blown out, and particularly, when the air flow leaves the air outlet 12 for a certain distance and is close to the ground, the air speed can be higher, so that the air supply distance is longer, and the cooling air-raising and heating air-sinking air supply are facilitated.

Further, the shape of the air deflector 50 and the shapes of the two air guide surfaces are further optimized and limited in the embodiment of the utility model, so that the flow fields on the two sides of the air deflector 50 are further optimized, and the air flow loss is reduced. For example, as shown in fig. 1, the wind deflector 50 can be rotationally symmetrical about a rotational symmetry axis x parallel to the length direction thereof, and the rotation angle is 180 °. That is, the concave sections AE of the first air guide surface 51 and the concave sections GF of the second air guide surface 52 have the same shape, and the convex sections EG of the first air guide surface 51 and the convex sections FA of the second air guide surface 52 have the same shape. The first half of the AEF of the deflector 50 is rotated about the x-axis, and after 180 ° rotation, it will coincide with the second half of the GFE. The axis of rotation x of the air deflection plate 50 may coincide with the axis of rotational symmetry x.

The concave section AE of the first air guide surface 51 can be formed by smoothly connecting a plurality of sections, and each section can be a circular arc section or a straight line section; the convex section of the first wind guide surface 51 is an integral arc section. For example, in fig. 1, the concave section AE of the first air guiding surface 51 includes a circular arc section ED, a circular arc section DC, a circular arc section CB, and a straight line section BA, and by providing a plurality of circular arc sections, the overall shape is more suitable for the flow characteristics of the fluid, and the loss is reduced. The outlet section of the first air guiding surface 51 is set as a straight line section BA, so that the air flow can flow out of the first air guiding surface 51 more straightly and smoothly. As shown in fig. 4, the concave section AE of the first wind guiding surface 51 may include a circular arc section EC, a circular arc section CB, and a straight line section BA. The convex section FA of the second air guiding surface 52 has the same shape as the convex section EG of the first air guiding surface 51, and also includes corresponding sections.

FIG. 5 is a cross-sectional view of a wind deflector 50 according to yet another embodiment of the present invention; fig. 6 is a schematic structural view of a wall-mounted air conditioning indoor unit having the air guide plate 50 shown in fig. 5.

In some embodiments, as shown in fig. 5 and 6, the concave section AE and the convex section EG of the first wind guiding surface 51, the convex section AF and the concave section FG of the second wind guiding surface 52 may be only one integral circular arc section. In some embodiments, as shown in fig. 5 and 6, the rotation axis of the wind deflector 50 may be located at the first wind deflecting surface 51 and at the central portion in the width direction thereof.

As shown in fig. 1, in some embodiments, the thickness of the air guiding plate 50 is gradually increased and then gradually decreased in the extending direction from the first side to the second side. Thus, making the middle of the air deflection plate 50 relatively thicker and the ends more pointed, this shape makes the rear tip less resistant to the air flow and the front tip makes the air flow more easily escape from the air deflection plate 50, in short making the air flow loss smaller. Of course, the first and second edges of the air deflection plates 50 are not sharp edges, but are preferably rounded.

Fig. 7 is a schematic structural view of a wall-mounted air conditioning indoor unit having an equal thickness air guide plate 50. In other embodiments, as shown in fig. 7, the thickness of the air deflection plate 50 remains constant in the direction extending from the first edge to the second edge.

Fig. 8 is a schematic structural view of a wall-mounted air conditioning indoor unit having a pop-up vent; fig. 9 is a schematic view showing the structure of a wall-mounted air conditioning indoor unit having a horizontal vent.

As shown in fig. 8, in some embodiments, the front air duct wall 200 may be provided with a plurality of vent holes 13 penetrating through the front panel of the housing 10 to allow a part of the air flow within the air duct 20 to be blown out through the plurality of vent holes 13.

As shown in fig. 8, the plurality of vent holes 13 may be extended obliquely upward and forward to allow the airflow to flow upward and forward to enhance the upward effect of the airflow. As shown in fig. 9, the plurality of vent holes 13 may be extended horizontally so that the airflow therein is blown out straight ahead.

Fig. 10 is a schematic structural view of a wall-mounted air conditioning indoor unit having an outer guide plate 60; fig. 11 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 10 after the outer guide 60 is rotated to another angle.

In the embodiment of the present invention shown in fig. 2 to 9, the air deflector 50 can be used to open and close the air outlet 12. When the wall-mounted air conditioner indoor unit is in an operating state, the air deflector 50 opens the air outlet 12 to guide the air outlet direction. When the wall-mounted air conditioning indoor unit is in a shutdown state, the air deflector 50 closes the air outlet 12.

In the embodiment shown in fig. 10 and 11, an outer guide plate 60 is further disposed at the air outlet 12, the outer guide plate 60 is an arc-shaped plate, one end of which is pivotally mounted at the rear end of the air outlet 12 for opening and closing the air outlet 12, and when the air outlet 12 is closed, the air guide plate 50 is covered inside the housing 10. Therefore, in this embodiment, the air outlet 12 is opened and closed by the outer guide 60, and the air guide plate 50 exclusively guides air. Since the outer guide 60 has an arc shape, it can also contribute to wind lifting even in the state shown in fig. 10. Because the pivot axis y of the outer guide plate 60 is located at the rear end of the air outlet 12, when the air outlet 12 needs to supply air with a large air volume or other conditions that do not need the interference of the outer guide plate 60 exist, the pivot axis y can be rotated to a position right below the bottom wall of the housing 10 shown in fig. 11 so as to be completely far away from the air outlet 12, and the air outlet of the air outlet 12 cannot be interfered.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
