The existing scheme is that an air deflector and a swing blade group are arranged at an air outlet, the air outlet angle of one dimension of the air outlet is adjusted through the air deflector, and the air is swung in the other dimension through the swing blade. The prior air conditioner adopts the air guide structure in a large amount, the use experience and the product appearance tend to be consistent, and the product grade is difficult to be improved.
Therefore, how to realize innovation in the aspect of the air guiding structure becomes a technical problem to be solved in the air conditioning industry.

The invention aims to provide an innovative air guide device and an air conditioner applying the same, so as to improve the distinguishing degree of products and the use experience of users.
A further object of the present invention is to provide an air guide device that combines both directivity of the air guide and air flow diffusivity.
In one aspect, the present invention provides an air guiding device for an air conditioner, configured to be rotatably installed at an air outlet of the air conditioner, so as to guide an air outlet direction of the air outlet;

Optionally, the two plate bodies are symmetrical about a plane and are centrosymmetric about the rotation axis of the air guiding device.
In another aspect, the present invention also provides an air conditioner, including:
the shell is internally provided with an air duct, and an outlet of the air duct forms an air outlet of the air conditioner; and
the wind guiding device according to any one of the preceding claims, which is arranged at the air outlet to guide the air outlet direction of the air outlet.
Optionally, the air conditioner is a mobile air conditioner.
Optionally, the air duct is defined by a first air duct wall and a second air duct wall which are arranged at intervals, and the sections of the first air duct wall and the second air duct wall adjacent to the air outlet are concave arc sections with central axes parallel to the rotation axis of the air guiding device.
Optionally, the air duct is provided with a necking part with an air outlet area smaller than that of the upstream side and the downstream side, and the two circular arc sections extend from the tail end of the necking part to the downstream direction of air flow.
Optionally, the air outlet is arranged at the top of the front side of the shell and is opened forwards and upwards;
the first air duct wall is positioned at the rear upper part of the second air duct wall, the central angle of the circular arc section of the first air duct wall is between 80 and 100 degrees, and the central angle of the circular arc section of the second air duct wall is between 10 and 20 degrees, so that the section of the air duct adjacent to the air outlet is in a flaring shape which is opened forwards and upwards.

The embodiment of the invention provides an air guide device for an air conditioner, which is used for being rotatably arranged at an air outlet of the air conditioner so as to guide the air outlet direction of the air outlet. Air conditioners are used to condition indoor air such as refrigeration/heating, dehumidification, introduction of fresh air, and the like. The air guide device of the embodiment of the invention can be applied to various types of air conditioners, including wall-mounted air conditioners, vertical air conditioners, ceiling-mounted air conditioners, mobile air conditioners and the like.
FIG. 1 is a schematic diagram of an air guiding device 50 according to an embodiment of the present invention; fig. 2 is a schematic view of an air conditioner according to an embodiment of the present invention; fig. 3 is a schematic cross-sectional view of the air conditioner shown in fig. 2. Fig. 2 and 3 illustrate an embodiment of a mobile air conditioner.
As shown in fig. 1 to 3, the air guiding device 50 according to the embodiment of the present invention may generally include two plate bodies 51, 52 and at least one connection portion 53. The two plate bodies 51, 52 are arranged at intervals and connected by at least one connecting portion 53 to achieve fixing of the relative positions. For example, as shown in fig. 1, the number of the connection portions 53 is two and each of them is plate-shaped, and the two connection portions 53 are connected to both ends of the two plate bodies 51, 52 in the longitudinal direction, so that the air guide device 50 as a whole has a square tubular structure. Of course, other connecting portions may be provided at the central portions or other portions of the two plate bodies. When the air guiding device 50 guides air, the air flow channel 501 between the two plates 51 and 52 can guide the air flow direction, and the outer side surfaces of the two plates 51 and 52 can also guide the air flow direction.
A motor may be provided in the air conditioner for driving the air guide 50 to rotate. As shown in fig. 1, the connection portion 53 may be provided with a connection hole so as to facilitate connection of the rotation shaft of the motor.
In the embodiment of the present invention, in the direction from the air inlet end a to the air outlet end B of the air guiding device 50, the distance between the two plate bodies 51 and 52 is gradually reduced and then gradually increased. When the air guiding device 50 guides air, the air flowing through the air guiding device is the air inlet end A, and the air flowing through the air guiding device is the air outlet end B. For example, in fig. 1, the air guide 50 may be formed in a long shape, such that the rotation axis x is parallel to the longitudinal direction thereof, and the both ends in the width direction thereof are the air inlet end a and the air outlet end B, respectively. In the embodiment of the present invention, in the direction from the air inlet end a to the air outlet end B of the air guiding device 50, the distance between the two plate bodies 51 and 52 is gradually reduced and then gradually increased, so that the air flow channel 501 formed between the two plate bodies is gradually reduced and then gradually expanded, that is, the middle is narrower, and the two openings are wider. The airflow passage of this shape has a supercharging effect on the airflow flowing therethrough. As shown in fig. 3, when the wind guiding device 50 guides wind, the wind force of the air flow flowing out of the air flow channel is stronger, the wind guiding directivity is stronger, and the air supply distance is longer. Furthermore, the distance between the two plates 51, 52 in the outlet section increases gradually, which causes a certain degree of diffusion of the air flow during the air guiding. It can be seen that the air guiding device 50 according to the embodiment of the invention is novel and unique, and can also combine the air guiding directivity and the air diffusing property, so that the main body of the air flow can be guided to the area where cold air/hot air is most needed, and part of the air flow can be diffused and blown out, so that other areas in the room can also have cold air/hot air blowing.
In the direction from the air inlet end a to the air outlet end B of the air guiding device 50, the two plate bodies 51, 52 are preferably extended along a curve so that the distance between the two plates is smoother, and the sudden change does not cause wind power loss. For example, in some embodiments, as shown in fig. 1 to 3, at least one of the two plates 51, 52 is an arc plate with a central axis parallel to the rotation axis x of the wind guiding device 50 and a convex side facing the other plate. For example, both plate bodies 51, 52 may be arcuate plates.
In other embodiments, at least one of the two plates 51, 52 is a hyperbolic plate having a central axis parallel to the rotation axis x of the air guiding device 50 and a convex side facing the other plate. The hyperbola is a conic, and the standard equation is x 2 /a 2 -y 2 /b 2 =1. For example, both plate bodies 51, 52 may be hyperbolic plates. Of courseOne of the two plate bodies 51, 52 may be an arcuate plate and the other may be a hyperbolic plate. In this embodiment, the plate bodies 51 and 52 are arc-shaped plates or hyperbolic plates, so that the airflow channel 501 which is gradually reduced and then gradually expanded has better flow guiding performance, smaller resistance and better supercharging effect.
In some embodiments, referring to fig. 4, the rotational axis x of the wind guiding device 50 is located on the connection plane M of the central axes x1 and x2 of the two plates 51, 52. The rotational axis x of the two air guides 50 may be equidistant from the center axes of the two plates 51 and 52, that is, xx1=xx2. In some embodiments, referring to fig. 4, the two plates 51, 52 of the wind guiding device 50 are symmetrical about a plane N and are centrally symmetrical about the rotational axis x of the wind guiding device 50.
By limiting the rotation axis position, symmetry characteristics and the like of the air guide device 50, the embodiment of the invention ensures that the air flow channel which is gradually contracted and gradually expanded is better in flow guiding performance, smaller in resistance and better in supercharging effect.
The invention further provides an air conditioner. The air conditioner may be various types of air conditioners including wall-mounted air conditioners, floor air conditioners, ceiling air conditioners, mobile air conditioners, and the like.
The air conditioner includes a housing 10 and an air guiding device 50 as described in any of the above embodiments. An air duct 20 is formed inside the casing 10, and an outlet of the air duct 20 constitutes an air outlet 12 of the air conditioner. The air duct 20 is used for conveying conditioned air (cold air, hot air, fresh air or purified air) of the air conditioner to the air outlet 12, and then conveying the conditioned air from the air outlet 12 to the indoor environment to complete the conditioning of the indoor air. A fan 30 may be disposed within the duct 20 to facilitate the flow of air. The fan 30 may be a cross-flow fan. The air guiding device 50 is disposed at the air outlet 12 to guide the air outlet direction of the air outlet 12.
In some embodiments, as shown in fig. 2 and 3, the air conditioner is a mobile air conditioner. The mobile air conditioner is an integral air conditioner, and various components of a refrigerating system thereof, including a compressor, a condenser 60, an evaporator 40, a throttling device and the like, are all arranged in one casing 10 of the mobile air conditioner, and rollers are arranged at the bottom of the casing 10 so as to facilitate the movement of the positions thereof.
The compressor and condenser 60 may be disposed at a lower portion of the inner space of the case 10, and the evaporator 40 and the duct 20 may be disposed at an upper portion of the inner space of the case 10. The evaporator 40 may be abutted against the inside of the rear wall of the case 10, and the rear wall of the case 10 may be provided with an air inlet for introducing indoor air. The evaporator 40 covers the inlet of the air duct 20 so that the air entering the air duct 20 is the air flow that exchanges heat with the evaporator 40.
In some embodiments, as shown in FIG. 3, the air chute 20 is defined by first and second air chute walls 21, 22 that are spaced apart. The sections of the first air duct wall 21 and the second air duct wall 22 adjacent to the air outlet 12 are concave arc sections, namely an arc section ab and an arc section cd, of which the central axis is parallel to the rotation axis x of the air guiding device 50. Therefore, the section of the air duct 20 adjacent to the air outlet 12 is in a flaring shape, which is beneficial to improving the air outlet static pressure of air flow and improving the air outlet quantity. For example, as shown in fig. 4, the two plate bodies 51, 52 may be symmetrical about a plane N and centered about the rotational axis of the wind deflector 50. The center axes of the circular arc segments of the first duct wall 21 and the second duct wall 22 are each made to coincide with the rotation axis x of the air guide 50.
In some embodiments, as shown in fig. 3 and 4, the air outlet 12 may be provided at the top of the front side of the casing 10 and opened toward the front and upper sides. The included angle between the plane of the air outlet 12 and the horizontal plane is preferably 15-35 degrees, which is beneficial to air supply forward and upward, so as to consider the air supply distance and the air supply range. The first air duct wall 21 is located at the rear upper side of the second air duct wall 22, the central angle of the arc section of the first air duct wall 21 is between 80 ° and 100 °, and the central angle of the arc section of the second air duct wall 22 is between 10 ° and 20 °, so that the section of the air duct 20 adjacent to the air outlet 12 is in a flaring shape opening forward and upward, thereby enabling the static pressure of the air outlet airflow to be larger and the air quantity to be larger.
In some embodiments, as shown in fig. 3 and 4, the duct 20 is made to have a reduced neck portion having an air outlet area smaller than the upstream and downstream sides thereof, specifically, the reduced diameter portion is defined by the ea section of the first duct wall 21 and the fc section of the second duct wall 22. Two circular arc segments ab, cd extend from the end of the neck portion in the downstream direction of the air flow. In this embodiment, by providing the diameter-reducing portions, the sections of the air duct 20 adjacent to the air outlet 12 are in a flaring shape, which is beneficial to improving the static pressure of the air outlet and improving the air outlet quantity.

As shown in fig. 4, the air guiding device 50 is at an oblique blowing angle, the air flow is guided forward and upward by the air flow channel 501 of the air guiding device 50 so as to be blown to a higher and longer distance, and the air flow is outwards diverged and guided by the outer side surfaces of the two plate bodies 51 and 52 so as to be wider in coverage range.
As shown in fig. 5, the air guiding device 50 is at a flat blowing angle, and the air guiding device 50 is closer to the first air duct wall 21, and the air is mainly discharged from the gap between the air guiding device 50 and the second air duct wall 22, so that the air flow is guided forward.
As shown in fig. 6, the air guide 50 is at an upward blowing angle, so that the air flow is guided directly upward by the air flow passage 501 of the air guide 50. The air flow is guided obliquely upward by the outer side surfaces of the two plates 51, 52 so as to widen the air blowing range.
As shown in fig. 7, the air guide 50 is at a diagonal blowing angle and faces upward and rearward so as to guide air upward and rearward.
As shown in fig. 8, the air guiding device 50 is at a closing angle, and the air guiding device 50 shields the air outlet 12. When the air conditioner is in a stopped state, the air guide 50 may be rotated to the closing angle.
