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 conditioning indoor unit having the air guide plate of fig. 1.

As shown in fig. 1 and 2, the air deflector 50 according to the embodiment of the present invention is rotatably mounted at the outlet 12 of the wall-mounted indoor unit of an air conditioner about a rotation axis parallel to the length direction thereof, and is used for guiding the air outlet direction of the outlet 12. The air deflector 50 is a long strip with the length direction parallel to the length direction of the air outlet, and the rotation axis of the air deflector 50 is parallel to the length direction.

The air guide plate 50 includes a plate body 51 and a plurality of inner plates 52 and 53. The air deflector body 51 is rotatably mounted to the casing 10 and directly connected to the casing 10. The air guiding plate body 51 has a plate-shaped main body for guiding air, and may further include a hole, a shaft, and other structures for rotatably connecting with the housing 10.

The inner plates 52, 53 are directly or indirectly fixed to the first side surface of the air deflector body 51 and are sequentially spaced apart from each other in a direction away from the first side surface 511 of the air deflector body 51. The two large surfaces of the air deflector body 51 for guiding air are a first side surface 511 and a second side surface 512 respectively. The inner plate 52 adjacent to the air guiding plate body 51 is directly fixed to the air guiding plate body 51, and specifically, may have a plurality of connecting ribs to fix the two. The other inner plate bodies are not adjacent to the air deflector body 51 and cannot be directly fixed to the air deflector body 51, so that the other inner plate bodies are fixed to the adjacent inner plate bodies, and specifically, the other inner plate bodies can also be fixed through a plurality of connecting ribs, and the way is that the other inner plate bodies are indirectly fixed to the air deflector body 51. In short, the air guiding plate body 51 and the inner plate bodies 52 and 53 of the respective layers form an integral air guiding plate 50, which may be an integrally formed part.

An air outlet interval is formed between the air deflector body 51 and the adjacent inner plate body 52, and an air outlet interval is also formed between the adjacent inner plate bodies 52 and 53 for allowing air flow to blow out. Of all the air outlet intervals, the thickness of the air outlet interval farther from the air deflector body 51 is smaller.

The air deflector 50 of the embodiment of the utility model comprises an air deflector body 51 and a multi-layer inner plate body 52 and 53, so that the air deflector 50 forms a multi-layer structure. When the air deflector 50 conducts air guiding, a part of the air outlet flow is guided by the air deflector body 51, another part of the air outlet flow can enter the air outlet interval between the air deflector body 51 and the inner plate body adjacent to the air deflector body, and the air outlet interval between the two adjacent inner plate bodies 52 and 53, the air deflector body 51 and the multilayer inner plate bodies 52 and 53 guide the air outlet direction of the air outlet flow together, so that the multi-layer guiding effect is realized, the air supply flow direction discharged from the air outlet 12 is uniform, the air flow is combed more smoothly, and the comfort level of a user is better.

In the air deflector 50 according to the embodiment of the present invention, the thickness of the air outlet interval that is farther from the air deflector body 51 is particularly made smaller, so that the blowing air flow at a far position of the air deflector body 51 (too far from the air deflector body 51, the guiding force by the air deflector body 51 is weak) is more strongly guided by the inner plate body.

The number of layers of the inner plate body can be two layers, three layers, four layers or more. Referring now to fig. 1, the structure of the air deflector 50 will be further described, taking two layers as an example.

For example, as shown in fig. 1, the number of the inner plates 52 and 53 may be two, and the first inner plate 52 and the second inner plate 53 may be arranged in this order in the direction away from the first side 511 of the air guide plate body 51. The thickness of the air outlet interval between the first inner plate 52 and the air guiding plate body 51 is h2, and the thickness of the air outlet interval between the second inner plate 53 and the first inner plate 52 is h 1. h2 is 1.5 to 2.5 times, specifically 2 times, that of h 1. The orthographic projection of the first inner plate 52 to the air deflector body 51 falls on the air deflector body 51, not on the extension line thereof. The orthographic projection of the second inner panel 53 onto the first inner panel 52 falls on the first inner panel 52 rather than on an extension thereof. That is, the width of the first inner panel 52 is smaller than that of the air guide plate body 51, and the width b2 of the second inner panel 53 is smaller than that b1 of the first inner panel 52. The width direction of the air deflector body 51 is the direction of the air flow along the first side 511 of the plate body of the air deflector 50. The width direction of each layer of the inner plate bodies 52, 53 is the direction in which the air flows along the inner plate bodies 52, 53. More preferably, the width of the second inner plate 53 is smaller than 1/2 of the width of the first inner plate 52, and the width of the first inner plate 52 is smaller than 1/3 of the width of the air deflector body 51.

Thus, the outer side of the second inner plate 53 forms a low wind speed area, an acceleration area is formed between the second inner plate 53 and the first inner plate 52, and the pressure of the airflow is obviously increased when the airflow passes through the acceleration area, which is beneficial to improving the air supply distance. A flow guiding area is formed between the first inner plate 52 and the air guiding plate body 51, and is mainly used for guiding the air flow direction of the main air flow part.

In addition, in the present embodiment, the width of each layer of inner plate 52, 53 is designed to be smaller than the air guiding plate body 51, so as to avoid that the air guiding distance of the air outlet interval is too long, which causes too large resistance of the air flow, and the air volume and the air speed of the air outlet 12 are excessively affected. Further, the width of the inner plate body further from the air guide plate main body 51 is smaller, so that the air flow can smoothly enter each air outlet interval and be guided by the inner plate bodies 52 and 53. No matter the air current flows to the first side surface 511 at an angle parallel to the air deflector body 51 or impacts the first side surface 511 at an inclined angle, the air current can better enter each air outlet interval.

When the air guide plate 50 is in a state where the first side 511 faces upward, the end portions of the air guide plate body 51 and the inner plates 52 and 53 facing the outside of the air outlet 12 are air outlet ends, and the end portions facing the inside of the air outlet 12 are air inlet ends. Referring to fig. 1 and 3, the end D of the air deflector body 51 is an air outlet end, and the end a is an air inlet end. The H end of the first inner plate 52 is an air outlet end, and the J end is an air inlet end. The K end of the second inner plate 53 is an air outlet end, and the S end is an air inlet end. When the air deflector 50 is in a state that the first side 511 faces upward, the air flow flows from the air inlet end to the air outlet end.

In some embodiments, as shown in fig. 1, the air outlet ends of the air deflector body 51 and the inner plate bodies 52 and 53 in each layer are located on the same plane N, so that the air flows in the air outlet intervals in each layer flow out simultaneously, and the air flows in each layer are parallel to each other, so that the air flow directions are combed more orderly. Furthermore, an included angle p (referred to as a non-obtuse angle) between a plane where the air outlet end of the air deflector body 51 and each layer of the inner plate bodies 52 and 53 is located and the tangential direction of the air outlet end of the air deflector body 51 is between 80 ° and 90 °. In this way, each layer of the inner plate 52 and 53 is close to the air outlet end of the air guiding plate body 51, so that the inner plate 52 and 53 mainly guides the direction of the air flow close to and away from the air guiding plate 50, thereby ensuring the direction of the finally flowing air flow.

In some embodiments, as shown in fig. 1 and 3, the first lateral surface 511 includes a first straight line segment AB, an inner concave arc segment BC, and a second straight line segment CD sequentially connected to each other in a direction from the air inlet end to the air outlet end. The second side 512 of the air deflector 50 opposite to the first side 511 is outwardly convex, so that the overall shape of the air deflector body 51 is curved toward one side. The first straight line segment AB forms an angle with the second straight line segment CD of between 150 ° and 170 °, preferably 160 °. The profile design of the present embodiment makes the wind direction guiding strength of the wind deflector body 51 stronger. The first inner plate 52 and the second inner plate 53 may be straight or arc-shaped due to their narrow width.

Fig. 2 is a schematic structural view of a wall-mounted air conditioning indoor unit having the air guide plate 50 of fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 with the air deflector in a forward blowing state; fig. 4 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 with the air deflector in a down-blowing state; fig. 5 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when the air deflector is in a maximum outlet state.

As shown in fig. 2 to 5, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and at least one air deflector. The casing 10 is provided with an air outlet 12, and the air deflector is the air deflector 50 of any of the above embodiments, and is rotatably installed at the air outlet 12 around a rotation axis parallel to the length direction thereof.

The housing 10 may be an elongated shape in which the longitudinal direction (the direction perpendicular to the paper surface of fig. 2) is horizontally arranged. 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, and the discharged air flow is acted by the fan 40 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, and fresh air flow in a fresh air mode. The outlet 12 and the air guide plate 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 and rear duct walls 200, 100 are spaced apart front to rear 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 wind deflector 50

In some embodiments, as shown in fig. 2 to 5, the air outlet 12 is opened toward the front and the lower direction, so that the air outlet 12 can supply air both toward the front and toward the lower direction. The air guide plate 50 has a plurality of states so that the wall-mounted air conditioner indoor unit has a plurality of air supply modes.

As shown in fig. 2, the air deflector 50 has a closed state in which the outlet 12 is closed and the first side surface 511 faces the inside of the outlet 12. When the wall-mounted air conditioning indoor unit is in a shutdown state, the air deflector 50 is in a closed state to close the air outlet 12.

As shown in fig. 3, the air deflector 50 has a front blowing state in which the first side 511 faces upward to guide the airflow blowing forward or upward. At this time, the air outlet end of the air deflector body 51 and the air inlet ends of the inner plate bodies 52 and 53 in each layer face forward, and the air inlet ends face backward. When the wall-mounted air conditioner indoor unit is used for refrigerating, the air supply mode can be adopted, so that cold air is upwards guided by the first side surface 511, 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. At the same time, part of the outlet air flow is blown out to the front lower side through the outlet air gaps 510 and 520.

As shown in fig. 4, the air guide plate 50 has a downward blowing state in which the first side surface 511 faces rearward to guide the air flow blown downward. At this time, the air outlet end of the air deflector body 51 and each layer of inner plate bodies 52 and 53 faces upward, and the air inlet end faces downward. When the wall-mounted air conditioner indoor unit is used for heating, the air supply mode can be adopted, the air flow is guided by the first side surface 511 to be blown downwards, the air outlet direction of the air flow is closer to or reaches the vertical downward direction, the air flow reaches the ground more, and the carpet type sinking air supply effect is realized.

As shown in fig. 5, the air deflector 50 further has a maximum air outlet state that the first side surface 511 faces forward and upward to guide the airflow to blow out forward and downward. At this time, the air deflector 50 has the minimum guiding function to the air flow, which is beneficial to the air flow to be blown out more smoothly, so that the air quantity is maximized, and the refrigerating/heating speed is fastest.

It should be noted that the above example is only for describing the operation principle of the air deflector 50 in the present embodiment more clearly, and is not used to limit the operation mode (heating or cooling) of the wall-mounted air conditioner indoor unit when the air deflector 50 is located. The user can adjust the working position of the air guiding plate 50 at will according to the actual situation, for example, adjust the air guiding plate 50 to the forward blowing state in the heating mode, adjust the air guiding plate 50 to the downward blowing state in the cooling mode, and so on, which will not be described herein.

Thus, it should be appreciated by those skilled in the art that while various exemplary embodiments of the utility model have been shown and described in detail herein, many other variations or modifications which are consistent with the principles of this invention may be determined or derived directly 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.
