With the development of the times and the advancement of technology, users not only expect faster cooling and heating speeds from air conditioners, but also pay more and more attention to the comfort performance of air conditioners.

However, in order to achieve faster cooling and heating, it is unavoidable to need to carry out large-volume air supply. But, when the excessive cold wind or hot wind of wind speed directly blows human body, it will inevitably cause discomfort of human body. The human body is blown directly by cold wind for a long time and can also cause air-conditioning disease.

Therefore, how to realize the comfortable air supply of the air conditioner has become a technical problem to be solved urgently in the air conditioner industry.

Contents of the invention

The object of the present invention is to provide a wind deflector capable of realizing comfortable air supply of an air conditioner and an air conditioner having the same.

In one aspect, the present invention provides a wind deflector, comprising:

The wind deflector body is used to be rotatably installed at the air outlet of the air conditioner; and

Optionally, each inner guide plate is an arc-shaped plate with a straight side parallel to the rotation axis of the wind guide body and a convex surface facing the wind guide body.

Optionally, the number of at least one inner guide plate is one.

Optionally, in a direction parallel to the rotation axis of the wind deflector body, both ends of the inner guide plate are flush with both ends of the wind deflector body.

Optionally, the end of the air deflector body towards the inside of the air outlet is the windward end during wind guiding, and the end towards the outside of the air outlet is the wind outlet end; in the area of the air outlet.

On the other hand, the present invention also provides an air conditioner, which includes:

The wind deflector of the present invention includes a wind deflector body and an inner guide plate spaced apart from the inner surface of the wind deflector body. The inner guide plate and the air guide plate body jointly guide the flow direction of the airflow. Moreover, the inner guide plate also plays a role in splitting and interfering with the airflow at the air outlet, so that the airflow is blown to the room in a more dispersed and soft manner, making the wind feel closer to the natural wind and achieving the effect of comfortable air supply. At the same time, the double-layer air guide structure of the air guide plate can also avoid condensation at the air outlet during the cooling operation of the air conditioner.

Further, in the air deflector of the present invention, the inner guide plate is arranged inside the air deflector body, and when the air conditioner makes the air deflector body lift up to blow air, the inner guide plate can play the role of guiding the wind upward. In this way, there is no need to rotate the wind deflector body to an overly vertical state (that is, a state close to closing the air outlet), so as to avoid a large impact on the air output.

Furthermore, in the wind deflector of the present invention, each telescopic bracket is a parallelogram mechanism composed of four connecting rods hingedly connected, which has a simple and practical structure, high reliability and very stable support to the inner guide plate. Moreover, four telescopic brackets are used to respectively support the four corners of the inner guide plate, and the distance between each corner and the main body of the wind guide plate can be adjusted. In this way, not only the distance between the inner guide plate and the main body of the air guide plate can be adjusted, but also the included angle between the inner guide plate and the main body of the air guide plate can be adjusted, and the adjustment range is very large.

Furthermore, in the wind deflector of the present invention, the inner guide plate is arranged in the area close to the air outlet end of the wind deflector body, so as to not only enhance the wind guiding function of the inner guide plate, but also facilitate guiding the airflow to a preset direction, and can Avoid too wide inner guide plate width to increase wind resistance.

Furthermore, the air conditioner of the present invention realizes the function of preventing direct blowing by setting a human sensor. When a human body enters the indoor preset area, the rotation of the wind deflector is controlled to prevent the wind from directly blowing the human body, thereby achieving the effect of preventing direct blowing and improving the user's comfort experience.

detailed description

The air deflector according to the embodiment of the present invention and the air conditioner having the same will be described below with reference to FIG. 1 to FIG. 5 . Among them, the orientation or positional relationship indicated by "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "horizontal", etc. are based on the The orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the present invention .

An embodiment of the present invention provides a wind deflector. Fig. 1 is a schematic structural view of an air deflector according to an embodiment of the present invention, and Fig. 2 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present invention.

As shown in FIGS. 1 and 2 , the wind deflector 50 may generally include a wind deflector body 51 and at least one inner deflector 52 . The wind deflector body 51 is used to be rotatably installed at the air outlet 12 of the air conditioner, and its rotation axis is the x-axis marked in the figure. The wind deflector body 51 is used to open or close the air outlet 12, and when the air outlet 12 is opened, it can be controlled to rotate to different angles to change the direction of the air outlet 12, so that the wind blows to different indoor areas. Each inner guide plate 52 is installed on the inner side of the air guide body 51 at intervals from the inner surface of the air guide body 51 , so as to guide the airflow direction of the air outlet 12 together with the wind guide body 51 . As shown in FIG. 1 , when the air outlet 12 is closed, the surface 511 of the air deflector body 51 facing inside the air outlet 12 is an inner surface, and the surface 512 facing indoors is an outer surface.

Figure 1 shows the wind direction with arrows, as shown in Figure 1, when the air flow flows through the surface of the air guide plate body 51, it will be interfered by the inner guide plate 52, a part of the air flow flows out along the outside of the inner guide plate 52, and a part of the air flow flows from the inner guide plate 52 and the guide plate 52. The space between the wind plate bodies 51 flows out, that is, the airflow is split and broken up. After the airflow is dispersed by the inner guide plate 52, it will not be concentrated and blown to the room, and the blowing force will also be weakened, becoming softer, and the wind feeling is closer to the natural wind, achieving the effect of comfortable air supply. The double-layer air guide structure of the air guide plate 50 can also avoid condensation at the air outlet 12 during the cooling operation of the air conditioner

Fig. 3 is a schematic diagram of the state of the air conditioner shown in Fig. 2 after changing the distance between the inner guide plate 52 and the air deflector body 51, and Fig. 4 is a state diagram of the air conditioner shown in Fig. State diagram.

As shown in FIGS. 1 to 4 , in the embodiment of the present invention, each inner guide plate 52 is connected to the wind guide plate body 51 through at least one telescopic bracket 54 . The telescopic support 54 can change its own extension length and change the distance between its two ends through telescopic expansion. Both ends of the telescopic bracket 54 are respectively connected to the wind deflector body 51 and the inner guide plate 52 , so as to change the position of the inner guide plate 52 relative to the wind deflector body 51 by adjusting the extension length of the telescopic bracket 54 .

As shown in FIG. 1 , each telescopic bracket 54 may include a first link 541 and a second link 542 . A first end of the first connecting rod 541 is hinged to the inner guide plate 52 . A first end of the second connecting rod 542 is hinged to the wind deflector body 51 , and a second end is hinged to the second end of the first connecting rod 541 . The telescopic bracket 54 only includes the above-mentioned two connecting rods to realize its telescopic function, and the structure is very simple. Certainly, those skilled in the art should understand that after the two connecting rods are adjusted to a certain state, they should be kept relatively firmly in this state, so as to avoid easily changing their state under the pressure of the inner guide plate 52, So that the inner guide plate 52 can hold the position firmly. Specifically, the fit between the holes of the two connecting rods and the hinge shaft can be an interference fit.

As shown in FIG. 1 , each telescopic bracket 54 may further include a third link 543 and a fourth link 544 . A first end of the third link 543 is hinged to a first end of the first link 541 . The first end of the fourth link 544 is hinged to the first end of the second link 542 , and the second end is hinged to the second end of the third link 543 . The fourth link 544 forms a parallelogram mechanism together with the first link 541 , the second link 542 and the third link 543 . Compared with the scheme where only two connecting rods are provided, four connecting rods are used to form a parallelogram mechanism, so that the telescopic support 54 has higher reliability and better stability, and can better resist the telescopic support 54 (circling perpendicular to the wind guide). The torsional deformation of the axis of the surface of the plate body 51 makes the position of the inner guide plate 52 more stable, avoiding unnecessary shaking and displacement of the inner guide plate 52 caused by the strong air flow.

The expansion and contraction of the telescopic support 54 can be operated manually, and each connecting rod of the telescopic support 54 driven by a stepping motor can also be used to rotate to realize the expansion and contraction of the telescopic support 54 . The stepper motor can be installed on the wind deflector body 51, and the controller of the air conditioner can be used to control the operation process of the stepper motor. The specific structure will not be repeated.

In some alternative embodiments, the telescopic support can also be other structural forms capable of telescoping in the prior art. For example, the telescoping bracket can be a telescoping rod, which includes an outer cylinder and an inner rod telescopically inserted into the outer cylinder. These alternative structures will not be described in detail here.

Those skilled in the art can understand that the inner deflector 52 can be installed on the wind deflector body 51 with a telescopic bracket 54 , only need to ensure the structural strength of the telescopic bracket 54 and select a suitable installation position.

However, preferably, each inner guide plate 52 is configured with a plurality of telescopic brackets 54 to ensure the stability of the inner guide plate 52 . As shown in FIG. 1 , each inner guide plate 52 can be configured with four telescopic brackets 54 , and the four telescopic brackets 54 are respectively used to support the four corners of the inner guide plate 52 . In this way, the distance between each corner of the inner guide plate 52 and the wind guide plate body 51 can be adjusted independently. In this way, not only the distance between the inner guide plate 52 and the air deflector body 51 can be adjusted, but also the angle between the inner guide plate 52 and the air guide body 51 can be adjusted, and the adjustability is very good.

When adjusting the extension lengths of all telescopic brackets 54 with the same value or close to the same value, the distance between the inner guide plate 52 and the wind deflector body 51 can be changed, but the angle between the inner guide plate 52 and the air guide body 51 can not be changed. For example, in the state shown in Figure 2, the extension direction of the inner guide plate 52 and the wind guide plate body 51 is basically parallel and the distance between them is relatively large. state, so that the distance between the inner guide plate 52 and the wind guide plate body 51 is reduced but the included angle remains unchanged.

Adjust the extension length of all or part of the telescopic bracket 54 with at least two values, or when adjusting the extension length of part of the telescopic bracket 54 with the same value, the angle between the inner guide plate 52 and the wind deflector body 51 can be changed. For example, in the state shown in FIG. 2 , after only shortening the extension lengths of the two telescopic brackets 54 away from the air outlet end of the wind deflector body 51, the two telescopic brackets 54 near the air outlet end of the wind deflector body 51 are not adjusted. Finally, it is adjusted to the state shown in FIG. 4 , so that the angle between the inner guide plate 52 and the wind guide plate body 51 is changed.

In this way, the position of the inner guide plate 52 relative to the wind guide plate body 51 can be changed by adjusting the extension length of the telescopic bracket 54 according to the actual wind guide requirements, so as to achieve better wind guide and comfortable air supply effects.

For example, when the distance between the inner guide plate 52 and the air guide body 51 is relatively large, the distance between the inner guide plate 52 and the air guide body 51 is relatively far, and the effect of the inner guide plate 52 to split and disperse the airflow will become stronger, but The wind speed and air volume of the tuyere 12 are more influenced by the inner guide plate 52 . Therefore, if the user does not require much cooling/heating speed, but more to pursue the comfort of air supply, the distance between the inner guide plate 52 and the air guide plate body 51 can be adjusted, as shown in FIG. 2 .

When the distance between the inner guide plate 52 and the air guide plate body 51 is small, the inner guide plate 52 is closer to the air guide plate body 51, and the effect of the inner guide plate 52 to split and disperse the airflow will be weakened, but the wind speed and air volume of the air outlet 12 will be affected. The influence of the inner guide plate 52 is even smaller. Therefore, if the user pursues cooling/heating speed more (meaning that the air volume must be large), the distance between the inner guide plate 52 and the air guide plate body 51 can be adjusted to be smaller, as shown in FIG. 3 .

The included angle between the inner guide plate and the air guide plate body can change the wind direction of the inner guide plate. For example, in the state shown in Figure 4, the windward end of the inner guide plate is relatively close to the wind guide plate body, and the air outlet end is relatively far away from the air guide plate body. , so as to guide the wind upward. Of course, the air outlet end of the inner guide plate can also be relatively far away from the wind guide plate body, or the distances between the two lateral ends of the inner guide plate (the two ends along the rotation axis of the wind guide plate body) and the wind guide plate body are different.

In order to improve the air supply comfort, in the prior art, when the air conditioner is cooling, it is hoped that the air deflector guides the cold air to blow out as vertically upward as possible. However, when the air deflector is close to the limit wind deflecting angle of upward blowing, the angle between the air deflector and the plane where the air outlet is located is too small, that is, the opening is very small, the air deflector will seriously block the air outlet, and the air volume becomes very small . This limits the range of the wind deflecting angle of the wind deflector. Especially when the wind is directed vertically, it is difficult to take into account the angle of the wind and the air volume. However, in this embodiment, when the wind deflector guides the wind upward, the position of the inner guide plate 52 arranged on the inner surface of the wind deflector body 51 is relatively higher, which is beneficial to blow the wind upward. During cooling operation of the air conditioner, there is no need to rotate the air deflector body 51 to be too close to a vertical state, so as to ensure that the air deflector has a large enough opening to avoid affecting the air volume. That is, this embodiment takes into account both the air supply angle and the air volume.

As shown in Figure 1, it is preferable to make the inner guide plate 52 an arc-shaped plate whose straight side is parallel to the rotation axis x-axis of the wind guide body 51, and whose convex surface faces the wind guide body 51, so as to facilitate the wind to be more easily cooled during cooling. Lead nearly vertically upwards.

Only one inner guide plate 52 may be provided as shown in FIGS. 1 to 4 . In order to make the flow guide range of the inner guide plate 52 larger, in the direction parallel to the rotation axis (x-axis) of the air guide plate body 51, the two ends of the inner guide plate 52 are flush with the two ends of the air guide plate body 51 (that is, Make the inner guide plate 52 the same length as the wind guide plate body 51).

Of course, multiple inner guide plates 52 may also be provided. A plurality of inner guide plates 52 can be arranged sequentially along the direction parallel to the x-axis, or arranged inside the wind guide plate body 51 in other ways, and these implementations will not be repeated here.

As shown in Figure 1, when the wind deflector 50 guides the wind, the internal airflow of the air conditioner first passes through the air deflector body 51 toward the end (B end) inside the air outlet 12, and after being guided by the air deflector body 51, flows toward the air outlet. One end (A end) of 12 outsides is blown to indoor. Thus, the B end is defined as the windward end, and the A end is the windward end. The inner guide plate 52 can be arranged in the area close to the wind outlet end of the wind guide plate body 51 , so that the airflow can blow toward the inner guide plate 52 after being guided by the part of the wind guide plate body 51 near the windward end. That is, the inner guide plate 52 is made to turbulence at the end of the wind guiding period of the wind deflector body 51 , so that the turbulent airflow can be blown into the room more quickly. At the same time, preferably the ratio of the width of the inner guide plate 52 to the width of the air guide plate body 51 is between 1/4 and 1/2, so as to enhance and realize the air guide function of the inner guide plate 52, and to facilitate guiding the airflow to a predetermined position. direction. It can also avoid that the width of the inner guide plate 52 is too wide to increase the wind resistance.

The embodiment of the present invention also provides an air conditioner. The air conditioner can be a wall-mounted unit, a cabinet unit or various terminal models of central air conditioners. The following takes the wall-mounted machine as an example for introduction.

As shown in FIGS. 2 to 4 , the air conditioner may generally include a housing 10 on which an air inlet 11 , an air outlet 12 , and the wind deflector 50 of any of the above-mentioned embodiments are arranged. The wind deflector body 51 of the wind deflector 50 is rotatably installed at the air outlet 12 to realize various functions and effects described in the above embodiments.

The air conditioner also includes an evaporator 20 , a fan 30 , an air duct 40 , and swing blades 60 . The evaporator 20 is used for exchanging heat with the air entering the casing 10 from the air inlet 11 to form heat exchange air (specifically, cold air during cooling and hot air during heating). The inlet of the air duct 40 faces the evaporator 20 , and the outlet communicates with the air outlet 12 . The fan 30 can be a cross-flow fan, which is arranged at the inlet of the air duct 40 to promote air flow from the evaporator 20 to the air outlet 12 . The casing 10 is provided with a plurality of first installation arms 70 at the air outlet 12, and the air deflector body 51 is provided with a plurality of second installation arms 515 matching the plurality of first installation arms 70, and the second installation arms 515 can be It is rotatably mounted on the corresponding first mounting arm 70 . The swing blade 60 is used for swinging wind left and right.

The air outlet 12 can be located at the lower part of the front side of the housing 10 and is a long rectangle extending along the horizontal direction. Make the wind deflector body 51 a long rectangular shape matching the air outlet 12 . And the rotation axis (x-axis) of the wind deflector body 51 is parallel to the length direction of the wind deflector body 51 .

Fig. 5 is a schematic block diagram of an air conditioner according to an embodiment of the present invention. In some embodiments, as shown in FIG. 5 , the air conditioner may include a motor 53 , a human sensor 80 and a controller 90 .

The motor 53 is used to drive the wind deflector body 51 to rotate around its rotation axis. The human sensor 80 is installed on the casing 10 and is used to detect whether a human body enters the predetermined indoor area. This area can be part of the indoor area that the human body can enter, such as the bed and its vicinity, or it can be the entire indoor area. The human sensor 80 can be an infrared sensor. After the human detection sensor 80 detects that someone enters the preset area, it generates a human detection signal and transmits it to the controller 90 .

The user can choose whether the air conditioner enters the anti-direct blowing mode. When the air conditioner is in the anti-direct blowing mode, after the controller 90 receives the human body induction signal transmitted by the human sensor 80, the control motor 53 drives the wind deflector body 51 to rotate to a position where the wind avoids the human body (such as an upward blowing position or a downward blowing position). blow position). Also can make controller 90 control the angle of swing blade 60, make wind avoid human body. In this way, the effect of preventing direct blowing can be achieved, and the user's comfort experience is improved.

When the air conditioner is not in the anti-direct blowing mode, the controller 90 controls the rotation of the wind deflector according to other control signals sent by the user through the remote controller or other communication terminals, or according to the preset operation mode of the air conditioner.
