An air guide assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-6.
As shown in fig. 1 to 3, the air guide assembly 100 according to the embodiment of the present invention includes an upper air guide plate 1 and a lower air guide plate 2.
The upper air deflector 1 comprises a first air deflector 11 and a second air deflector 12, the first air deflector 11 being movable relative to the second air deflector 12 to vary the length of the upper air deflector 1. The lower air deflector 2 is located at the lower side of the upper air deflector 1, a gas passage 100a is defined between the lower air deflector 2 and the upper air deflector 1, one side surface of the lower air deflector 2 defining the gas passage 100a is formed into a convex curved surface 20a, and the convex curved surface 20a is projected in a direction away from the other side surface of the lower air deflector 2.
For example, as shown in fig. 1 to 3, the upper air guide plate 1 and the lower air guide plate 2 are disposed at a vertically spaced apart position, and a gas passage 100a is defined between a lower surface of the upper air guide plate 1 and an upper surface of the lower air guide plate 2, and the gas passage 100a has an inlet and an outlet, wherein the inlet may be located at a rear end of the gas passage 100a, and the outlet may be located at a front end of the gas passage 100 a. The upper surface of the lower air deflector 2 is formed as a convex curved surface 20a, and the convex curved surface 20a projects upward toward a direction away from the lower surface of the lower air deflector 2. The first air guide plate 11 and the second air guide plate 12 can be moved relatively to change the length of the upper air guide plate 1 in the front-rear direction, thereby changing the flow area of the gas passage 100 a.
Specifically, when the air guide assembly 100 is applied to the air conditioner 200, the air guide assembly 100 is rotatably provided at the air outlet 101a of the air conditioner 200, and the lower surface of the lower air guide plate 2 may protrude toward a direction away from the upper surface of the lower air guide plate 2, so that when the air conditioner 200 is in a closed state (not shown), the air guide assembly 100 swings to a proper angle to shield the air outlet 101a, and at this time, the lower surface of the lower air guide plate 2 may be matched with the surface of the air conditioner 200, thereby improving the aesthetic property of the entire air conditioner 200; when the air conditioner 200 is in a heating mode (as shown in fig. 4 and 6), the air guide assembly 100 swings to a proper angle, and the first air guide plate 11 and the second air guide plate 12 relatively move to change the length of the upper air guide plate 1, so that at least part of the air channel 100a adjacent to the outlet forms a tapered channel, and thus the air flow at the air outlet 101a flows from back to front in the air channel 100a, the upper air guide plate 1 guides the air flow to enhance the coanda effect of the air flow flowing along the lower air guide plate 2, so that the air flow can continue to flow downwards when flowing along the convex curved surface 20a of the lower air guide plate 2 to the front end of the lower air guide plate 2, and the air flow flows to the bottom layer of a room, so that the temperature distribution of the whole room is more uniform, and the effect of warming feet and warmth is realized; when the air conditioner 200 is in the cooling mode (as shown in fig. 5), the air guide assembly 100 swings to another suitable angle, and the first air guide plate 11 and the second air guide plate 12 relatively move to change the length of the upper air guide plate 1, so that at least part of the air channel 100a adjacent to the outlet forms a divergent channel, and thus the air flow at the air outlet 101a flows from back to front in the air channel 100a, the air supply area is larger, the air supply amount is ensured, and the cooling comfort of the air conditioner 200 is further improved.
According to the air guide assembly 100 of the embodiment of the invention, the first air guide plate 11 and the second air guide plate 12 can relatively move to change the length of the upper air guide plate 1, and one side surface of the lower air guide plate 2 defining the air channel 100a is formed into the convex curved surface 20a, so that the air guide assembly 100 can better guide the flow of air flow. When the air guide assembly 100 is applied to the air conditioner 200, the air guide assembly 100 can be adjusted according to the operation mode of the air conditioner 200, thereby improving the comfort of the user.
In the embodiment of the present invention, a chute 12a is formed on one of the first air guide plate 11 and the second air guide plate 12, and the other of the first air guide plate 11 and the second air guide plate 12 is formed in a shape that is adapted to the chute 12a so as to slide in the chute 12 a. Therefore, the structure is simple, the implementation is easy, the first air deflector 11 and the second air deflector 12 are convenient to move relatively, the relative position between the first air deflector 11 and the second air deflector 12 is quickly adjusted, and the length of the upper air deflector 1 is quickly changed.
Further, a chute 12a is formed on the second air deflection 12, the chute 12a being parallel to a side surface of the second air deflection 12 defining the air passage 100 a. For example, in the example of fig. 1 and 2, the chute 12a is located at the lower portion of the second air deflection 12, the chute 12a is parallel to the lower surface of the second air deflection 12, and at the same time, the lower surface of the first air deflection 11 and the lower surface of the second air deflection 12 are also parallel to each other, so that the first air deflection 11 slides back and forth along the chute 12a in the chute 12a to change the length of the upper air deflection 1 in the front-rear direction, thereby changing the flow area of the gas passage 100 a.
Of course, the chute 12a is formed at the upper portion or the middle portion of the second air deflector 12, and it is only necessary to realize that the first air deflector 11 can slide in the chute 12 a. It will be appreciated that the chute 12a may also be formed on the first air deflector 11, so that the second air deflector 12 slides within the chute 12a on the first air deflector 11, and the relative position between the first air deflector 11 and the second air deflector 12 may be quickly adjusted, thereby facilitating the change in length of the upper air deflector 1.
Alternatively, the length of the chute 12a is greater than or equal to the length of the first air deflection 11 in the cross section of the upper air deflection 1. Therefore, the first air deflector 11 can be completely moved into the chute 12a, so that on the cross section of the upper air deflector 1, the length of the upper air deflector 1 is greater than or equal to the length of the second air deflector 12 and less than or equal to the sum of the lengths of the first air deflector 11 and the second air deflector 12, and the length of the upper air deflector 1 has a larger variation range, so that the practical application can be better satisfied.
Specifically, when the air guide assembly 100 is applied to the air conditioner 200, as shown in fig. 1, 4 and 6, when the air conditioner 200 is in a heating mode, the air guide assembly 100 swings to a proper angle, and moves the first air guide plate 11 forward so that at least part of the first air guide plate 11 extends out of the chute 12a, at this time, the length of the upper air guide plate 1 is longer, so that at least part of the air channel 100a adjacent to the outlet forms a tapered channel, and thus the air flow at the air outlet 101a flows forward from back to back in the air channel 100a, the upper air guide plate 1 guides the air flow to enhance the coanda effect of the air flow flowing along the lower air guide plate 2, so that the air flow can continue to flow downward when flowing along the convex curved surface 20a of the lower air guide plate 2 to the front end of the lower air guide plate 2, so that the air flow flows to the bottom layer of the room, and the temperature distribution of the whole room is more uniform, and the effect of "warm foot and warm heart" is achieved; as shown in fig. 2 and 5, when the air conditioner 200 is in the cooling mode, the air guide assembly 100 swings to another suitable angle, and moves the first air guide plate 11 backward to make the first air guide plate 11 completely located in the chute 12a, at this time, the length of the upper air guide plate 1 is shorter, so that at least part of the air channel 100a adjacent to the outlet forms a tapered channel, and therefore the air flow at the air outlet 101a flows forward from behind in the air channel 100a, the air supply area is larger, the air supply amount is ensured, and the cooling comfort of the air conditioner 200 is further improved.
It can be appreciated that, when the air conditioner 200 is in the heating mode, the length of the extending chute 12a of the first air deflector 11 can be adjusted according to the actual situation, so as to better satisfy the actual application.
Specifically, the ratio of the lengths of the first air deflection 11 and the second air deflection 12 is a, and a satisfies: a is more than or equal to 1/3 and less than or equal to 1. That is, in the cross section of the air guide assembly 100, the ratio a of the length of the first air guide plate 11 to the length of the second air guide plate 12 is 1/3.ltoreq.a.ltoreq.1, so that when the air guide assembly 100 is applied to the air conditioner 200, the interference between the length of the first air guide plate 11 and other components of the air conditioner 200 caused by overlong length of the first air guide plate 11 in the rotating process of the air guide assembly 100 is avoided, the normal rotation of the air guide assembly 100 is ensured, and the influence on the air flow caused by the overlong length of the first air guide plate 11 is avoided.
Further, the wind guiding assembly 100 further comprises a connecting plate 3, and the upper wind guiding plate 1 and the lower wind guiding plate 2 are connected through the connecting plate 3. For example, as shown in fig. 1-3, the connection plate 3 is located between the upper air deflector 1 and the lower air deflector 2, the upper end of the connection plate 3 is connected with the upper air deflector 1, the lower end of the connection plate 3 is connected with the lower air deflector 2, and the plane where the connection plate 3 is located can be parallel to the flowing direction of the air flow in the air channel 100a so as to reduce the flowing resistance of the air flow and ensure the air supply distance.
For example, in the example of fig. 3, a plurality of connecting plates 3 are arranged between the upper air deflector 1 and the lower air deflector 2 at intervals left and right, so that the upper air deflector 1 and the lower air deflector 2 can be supported while the connection strength between the upper air deflector 1 and the lower air deflector 2 is ensured, and the stability of the shape of the gas channel 100a is ensured.
In some embodiments of the present invention, as shown in fig. 1 and 2, in the cross section of the lower air deflector 2, a line between two free ends of the lower air deflector 2 is a reference line 20b, the length of the reference line 20b is L, the maximum protruding distance from the convex curved surface 20a to the reference line 20b is H, where L and H satisfy: H/L is more than or equal to 1/10 and less than or equal to 1/4. Therefore, the phenomenon that the outward convex curved surface 20a tends to be gentle due to too small H/L is avoided, so that the air flow cannot be guided to flow downwards after passing through the lower air deflector 2, and meanwhile, the phenomenon that the air supply distance and the air quantity are influenced due to too steep H/L and too steep outward convex curved surface 20a is avoided, so that the guiding effect of the lower air deflector 2 on the air flow is ensured on the premise of ensuring the air quantity.
Optionally, on the cross section of the lower air deflector 2, the projection of the convex curved surface 20a includes at least one of a circular arc line, an elliptical line, a hyperbolic line, or a parabolic line. That is, on the cross section of the lower air deflector 2, the projection of the convex curved surface 20a may be any combination of at least two of circular arc line, elliptical line, hyperbola or parabola, of course, the number of circular arc line, elliptical line, hyperbola and parabola may be set according to the actual situation. Thereby, the diversity of the lower wind deflector 2 is enhanced, thereby improving the applicability of the wind guiding assembly 100.
Here, it is to be noted that "any combination" means an arrangement between a plurality of lines, for example, any combination between one circular arc line and one elliptical line means that along the flow direction of the gas flow in the gas passage 100a, the circular arc line may be arranged upstream of the gas flow and the elliptical line may be arranged downstream of the gas flow, or the circular arc line may be arranged downstream of the gas flow and the elliptical line may be arranged upstream of the gas flow.
Further alternatively, the projection of the convex curved surface 20a also includes a straight line on the cross section of the lower air deflector 2. That is, on the cross section of the lower air deflection plate 2, the projection of the convex curved surface 20a may be a combination of one of a circular arc line, an elliptical line, a hyperbolic line, or a parabolic line with a straight line, or any combination of at least two of a circular arc line, an elliptical line, a hyperbolic line, or a parabolic line with a straight line. Thereby, the diversity of the lower wind deflector 2 is further enhanced, thereby further improving the applicability of the wind guiding assembly 100.

Wherein, an air outlet 101a is formed on the housing 101, and the air guiding assembly 100 is disposed at the air outlet 101 a.
For example, as shown in fig. 4 and 5, a heat exchanger 102 and a fan 103 are provided in a housing 101, an air outlet 101a is formed at a front side of the housing 101, and an air guide assembly 100 is rotatably provided at the air outlet 101 a. When the air conditioner 200 is operated, the fan 103 blows the air flow after heat exchange by the heat exchanger 102 out of the air outlet 101a, and the air guiding assembly 100 can guide the air flow to change the flowing direction of the air flow.
Specifically, when the air guide assembly 100 is applied to the air conditioner 200, as shown in fig. 1, 4 and 6, when the air conditioner 200 is in a heating mode, the air guide assembly 100 swings to a proper angle, and moves the first air guide plate 11 forward so that at least part of the first air guide plate 11 extends out of the chute 12a, at this time, the length of the upper air guide plate 1 is long, so that at least part of the air channel 100a adjacent to the outlet forms a tapered channel, the upper air guide plate 1 guides the air flow to enhance the coanda effect of the air flow flowing along the lower air guide plate 2, so that the air flow flows to the bottom layer of the room, and the temperature distribution of the whole room is more uniform; as shown in fig. 2 and 5, when the air conditioner 200 is in the cooling mode, the air guide assembly 100 swings to another suitable angle, and moves the first air guide plate 11 backward to make the first air guide plate 11 completely located in the chute 12a, at this time, the length of the upper air guide plate 1 is shorter, so that at least part of the air channel 100a adjacent to the outlet forms a tapered channel, thereby the air supply area is larger, the air supply amount is ensured, and the cooling comfort of the air conditioner 200 is further improved.
According to the air conditioner 200 of the embodiment of the invention, by adopting the air guide assembly 100, the air supply distance is ensured, meanwhile, the temperature distribution in the room is more uniform, and the use comfort of a user is improved.
