With the development of the times and the advancement of technology, users not only expect air conditioners to have faster cooling and heating speeds, 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 supply air with a large air volume. However, when the cold air or hot air with excessive wind speed blows directly on the human body, it will inevitably cause discomfort to the human body. The long-term exposure of the human body to the cold wind 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.

Utility model content

The purpose of the utility model is to provide a wind deflector which can realize comfortable air supply of an air conditioner and an air conditioner having the same.

The further purpose of the utility model is to expand the air guide range of the air guide plate, so that the air conditioner can take into account the air outlet angle and air volume.

an air deflector body, which is used to be rotatably installed at the air outlet of the air conditioner casing around an axis parallel to its own length direction; and

a plurality of inner guide plates, which are arranged at intervals along the width direction of the air guide plate body on the inner side of the air guide plate body, and the length directions are all parallel to the length direction of the air guide plate body;

Each inner guide plate is rotatably mounted on the air guide plate body around an axis parallel to its own length direction, so as to change the airflow direction inside the air guide plate body by rotating to different angles.

Optionally, the air guide plate also includes: a plurality of connecting bars, each connecting bar is connected to an inner guide plate at different positions in the length direction, so that when one inner guide plate rotates, the inner guide plate drives the other inner guide plates to synchronize through the connecting bars. turn.

Optionally, the air deflector further includes: at least one first motor mounted on the air deflector body, and each first motor is used to drive an inner guide plate to rotate.

Optionally, the inner surface of the air deflector body is provided with a plurality of mounting seats arranged along the length direction of the air deflector body, and the mounting seats are used to connect to the housing; The space between adjacent length sections is used for accommodating the mounting seat; and the adjacent length sections with the inner guide plate of the first motor are connected by connecting shafts.

Optionally, the inner surface of the air deflector body is provided with a bearing seat for installing the connecting shaft.

Optionally, there is no direct connection structure between each length section of the inner guide plate without the first motor and the air guide plate body.

Optionally, the number of the plurality of inner guide plates is three; and only the two inner guide plates at both ends of the air deflector body in the width direction are each provided with a first motor.

Optionally, each length section of each inner guide plate is a straight side parallel to the length direction of the air guide plate body, and the convex surface faces the arc-shaped plate of the air guide plate body.

The wind guide plate of the utility model comprises a wind guide plate body and a plurality of rotatable inner guide plates. The inner guide plate and the air guide plate body jointly guide the airflow. In addition, the inner guide plate also plays the role of splitting and interfering with the air flow at the air outlet, so that the air flow is blown toward the room in a more dispersed and soft manner, making the wind feel closer to natural wind and achieving the effect of comfortable air supply.

Further, after the main body of the air guide plate is rotated to a certain angle, the direction of the air guide plate can be further changed by rotating the inner guide plate, so that the wind guide angle range of the air guide plate is wider.

Further, when the wind deflector of the present invention and the prior art wind deflector are at the same opening (the same opening makes the air volume the same), the present invention can use the inner guide plate to further adjust the wind direction, so that the wind guide angle is larger. For this reason, when the air-conditioning and cooling make the air-guiding plate body rise to blow air, the inner guide plate can play the role of guiding the wind upwards. This eliminates the need to rotate the air deflector body to a state that is too vertical (ie, close to the state of closing the air outlet), so as to prevent the air output from being greatly affected.

Further, the air conditioner of the present invention realizes the function of preventing direct blowing by arranging a human-sensing sensor. When a human body enters the indoor preset area, the wind deflector is controlled to rotate to prevent the wind from blowing directly on the human body, so as to achieve the effect of preventing direct blowing and improve the user's comfortable experience.

Wherein, the orientation or positional relationship indicated by "front", "rear", "upper", "lower", "top", "bottom", "inside", "outside", "horizontal", etc. The orientation or positional relationship is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a reference to the present utility model. limits.

1 is a schematic structural diagram of an air deflector according to an embodiment of the present utility model; FIG. 2 is an enlarged view of the structure shown in FIG. 1 at part A; FIG. 3 is a schematic cross-sectional view of the air deflector shown in FIG. 1; FIG. 4 It is a schematic cross-sectional view of an air conditioner according to an embodiment of the present invention.

As shown in FIGS. 1 to 4 , the wind deflector 50 according to the embodiment of the present invention may generally include a wind deflector body 51 and a plurality of inner guide plates 52 , 53 and 54 . The air deflector body 51 is rotatably installed at the air outlet 12 of the air conditioner housing 10 around an axis parallel to its own length direction (x-axis), and is used to open and close the air outlet 12 and adjust the air outlet angle of the air outlet 12 . The air deflector body 51 is in the shape of an arc-shaped plate with a convex surface facing the outside of the air outlet 12 as a whole, and may also be a plate-shaped structure of other forms, so as to guide the airflow direction of the air outlet 12 . The plurality of inner guide plates 52 , 53 and 54 are arranged at intervals along the width direction of the air guide plate body 51 on the inner side of the air guide plate body 51 , and the length directions are all parallel to the length direction of the air guide plate body 51 . When the air deflector body 51 is in the state of closing the air outlet 12 , the side facing the inside of the casing 10 is called the inner side. Each inner guide plate 52 , 53 , 54 is rotatably mounted on the air guide plate body 51 about an axis parallel to its own length direction, so as to change the airflow direction inside the air guide plate body 51 by rotating to different angles. The longitudinal direction of the air outlet 12 and the longitudinal directions of the air guide plate body 51 and the inner guide plates 52 , 53 , and 54 can be arranged in the horizontal direction.

In the embodiment of the present invention, when the air flow inside the casing 10 is blown toward the air outlet 12 and flows through the surface of the air deflector body 51, it will be disturbed by the inner guide plates 52, 53, 54, and a part of the air flow will flow along the inner guide plates 52, 53. , 54 flow out, and a part of the airflow flows out from the spaced area between the inner guide plates 52, 53, 54 and the air guide plate body 51, that is, the airflow is split and scattered. After the airflow is dispersed by the inner guide plates 52, 53, and 54, it will not be blown into the room in a concentrated manner, and the blowing force will also be weakened, becoming softer, and the wind feeling is closer to natural wind, achieving the effect of comfortable air supply. The multi-layer air guide structure of the air guide plate can also avoid condensation at the air outlet when the air conditioner is running.

In addition, in order to improve the comfort of air supply, when the air conditioner is refrigerating, it is usually desirable that the air deflector guides the cold air to blow out vertically upward as much as possible. However, when the air deflector of the traditional air conditioner is rotated to the upper blowing angle close to the limit, the angle between the air deflector and the plane where the air outlet is located is too small, that is, the opening degree is small (the opening degree of the air deflector refers to the opening of the air deflector). The degree of the air outlet, when the air deflector completely closes the air outlet, the opening degree is zero. When the surface of the air deflector is close to perpendicular to the surface of the air outlet, the opening degree is 100%, and the air outlet is the smoothest), the air deflector will seriously block Outlet, the air volume becomes very small. This limits the wind guide angle range of the wind deflector. Especially in the vertical wind guide, it is difficult to take into account the wind guide angle and air volume.

However, in the embodiment of the present invention, after the wind deflector body 51 is rotated to a certain angle, the wind deflecting direction can be further changed by rotating the inner guide plates 52 , 53 and 54 . This is to make the wind guide angle range of the wind guide plate 50 larger in the embodiment of the present invention. Since the inner guide plates 52, 53, and 54 are positioned relatively high, it is beneficial to blow the wind upward. Therefore, it is not necessary to rotate the air deflector body 51 to a state that is too close to vertical during the air-conditioning cooling operation, so as to ensure that the air deflector 50 has a large enough opening degree to prevent the air volume from being affected. It can be seen that the embodiment of the present invention takes into account both the air supply angle and the air volume. Moreover, by providing multiple layers of inner guide plates, the air flow in each area of the width direction of the air deflector body 51 can be effectively guided (the arrows in FIG. 3 indicate the wind direction), which undoubtedly strengthens the airflow to the inside of the air deflector body 51 guide effect.

In some embodiments, as shown in FIGS. 1 and 2 , the wind deflector 50 may further include a plurality of connecting bars 57 . Different parts of each connecting bar 57 in the length direction are respectively connected to an inner guide plate 52, 53, 54, so that when one inner guide plate rotates, the inner guide plate drives the other inner guide plates to rotate synchronously through the connecting bar 57. Optionally, the connecting bar 57 can be made of plastic, and the connecting parts of the connecting bar 57 and the inner guide plates 52, 53, 54 can be freely bent with the rotation of the inner guide plates 52, 53, 54, so as to form a connection relationship similar to a hinge, without the need for Set up a more complex shaft hole structure. The plurality of connecting bars 57 are arranged along the longitudinal direction of the air deflector body 51 . Of course, the connecting bars 57 may not be provided, so as to independently adjust the angles of the inner guide plates 52 , 53 and 54 .

In some embodiments, the angle of the inner guide plates 52, 53, 54 can be adjusted by manually rotating them. In other embodiments, as shown in FIG. 2 , the wind deflector 50 further includes at least one first motor 58 . The first motors 58 are installed on the air deflector body 51 , and each first motor 58 is used to drive an inner guide plate to rotate. Both ends of the inner guide plate can be provided with shafts, and the shafts can be rotatably installed on the shaft seats provided at both ends of the air guide plate body 51 .

As shown in FIG. 1 , the inner surface 511 of the air deflector body 51 is provided with a plurality of mounting seats 515 arranged along the length direction of the air deflector body 51 , and the mounting seats 515 are used for connecting to the housing 10 . For example, as shown in FIG. 4 , the housing 10 is provided with the same number of mounting arms 70 as the mounting seats 515 , and each mounting seat 515 (through the shaft hole structure) is rotatably mounted on one mounting arm 70 . In order to make room for each mounting seat 515, each inner guide plate 52, 53, 54 is composed of a plurality of length segments arranged along the length direction of the air guide plate body 51, and the space between adjacent length segments is used for the mounting seat 515 . For example, as shown in FIG. 1 , four mounting seats 515 may be provided, which are arranged at equal distances along the length direction of the air deflector body 51 . Two of the mounting seats 515 are located at both ends of the air deflector body 51 in the longitudinal direction. Each inner guide 52, 53, 54 includes 3 lengths.

As shown in FIG. 1 , the adjacent length sections of the inner guide plates 52 and 54 provided with the first motor 58 can be connected by a connecting shaft 55 . In addition, the inner surface 511 of the air deflector body 51 is provided with a bearing seat 56 for installing the connecting shaft 55, so as to provide a more stable support to the inner deflector. There is no direct connection structure between each length section of the inner guide plate 53 without the first motor 58 and the air guide plate body 51, so as to simplify the structure of the air guide plate. For example, as shown in FIG. 1 , the number of the plurality of inner guide plates is three, which are the inner guide plate 52 , the inner guide plate 53 and the inner guide plate 54 respectively. Only the two inner guide plates 52 and 54 located at both ends of the wind deflector body 51 in the width direction are each provided with a first motor 58 . The middle inner guide plate 53 is not equipped with the first motor 58 , and has no direct connection structure with the air guide plate body 51 , and there is no connecting shaft 55 between adjacent lengths, so as to leave space for the mounting seat 515 .

As shown in FIG. 3 , each length section of each inner guide plate 52 , 53 , and 54 is a straight side parallel to the length direction of the air guide plate body 51 , and the convex surface faces the arc-shaped plate of the air guide plate body 51 , so as to facilitate the Directs the wind in a more vertical upward direction when cooling.

The second motor 59 is used to directly drive the wind deflector body 51 to rotate. The human-sensing sensor 80 is used to detect whether a human body enters a preset indoor area. The indoor preset area may be a part of the indoor area that the human body can enter, such as the bed and its vicinity, or may be the entire indoor area. The human sensor 80 may be an infrared sensor. After the human-sensing sensor 80 detects that a person enters the preset area, a human-sensing signal is formed and transmitted to the controller 90 .

The user can choose whether the air conditioner enters the direct blowing prevention mode. When the air conditioner is in the anti-direct blowing mode, after receiving the human body sensing signal transmitted by the human sensing sensor 80, the controller 90 controls the operation of the second motor 59 to rotate the air deflector body 51 to a position where the wind avoids the human body (for example, the upper blow position or blow down position). The controller 90 can also be made to control the movement of the swing blade 60 to keep the wind away from the human body. In this way, the effect of preventing direct blowing can be achieved, and the comfort experience of the user is improved.

When the air conditioner is not in the direct blow prevention mode, the controller 90 controls the air deflector body 51 and the swing vane 60 according to other control signals sent by the user through the remote control or other communication terminals, or according to the preset operation mode of the air conditioner. turn.
