Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air guide plate and an air conditioner having the same. Background Art

[0002] 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.

[0003] However, in order to achieve faster cooling and heating, it is inevitable to supply air with a large air volume. However, when the cold or hot air with too high wind speed blows directly on the human body, it will inevitably cause discomfort to the human body. If the human body is directly blown by cold air for a long time, it will also cause air conditioning disease.

[0004] Therefore, how to achieve comfortable air supply of air conditioners has become a technical problem that needs to be solved urgently in the air conditioning industry. Summary of the invention

[0005] The object of the present invention is to provide an air guide plate capable of realizing comfortable air supply for an air conditioner and an air conditioner having the same.

[0006] A further object of the present invention is to expand the air guiding range of the air guide plate so that the air conditioner can take into account both the air outlet angle and the air volume.

[0007] In one aspect, the present invention provides a wind deflector, comprising:

[0008] An air guide plate body, which is used to be installed at the air outlet of the air conditioner housing so as to be rotatable around an axis parallel to its length direction; and

[0009] A plurality of inner guide plates 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 of the inner guide plates are parallel to the length direction of the air guide plate body;

[0010] Each inner guide plate can be rotatably mounted on the air guide plate body around an axis parallel to its own length direction, so as to change the air flow direction inside the air guide plate body by rotating to different angles.

[0011] Optionally, the air guide plate further includes: a plurality of connecting strips, each connecting strip being connected to an inner guide plate at different positions in the length direction, so that when an inner guide plate rotates, the inner guide plate drives other inner guide plates to rotate synchronously through the connecting strips.

[0012] Optionally, the air guide plate further includes: at least one first motor installed on the air guide plate body, each first motor is used to drive an inner guide plate to rotate.

[0013] Optionally, the inner surface of the air guide plate body is provided with a plurality of mounting seats arranged along the length direction of the air guide plate body, and the mounting seats are used to be connected to the shell; each inner guide plate is composed of a plurality of length segments arranged along the length direction of the air guide plate body, and the space between adjacent length segments is used to accommodate the mounting seats; and the adjacent length segments of the inner guide plate equipped with the first motor are connected by a connecting shaft.

[0014] Optionally, a bearing seat for mounting a connecting shaft is provided on the inner surface of the air guide plate body.

[0015] Optionally, there is no direct connection structure between each length section of the inner guide plate not equipped with the first motor and the air guide plate body.

[0016] Optionally, the number of the plurality of inner guide plates is three; and only two inner guide plates located at both ends in the width direction of the air guide plate body are each equipped with a first motor.

[0017] Optionally, each length section of each inner guide plate is a curved plate with a straight side parallel to the length direction of the air guide plate body and a convex surface facing the air guide plate body.

[0018] On the other hand, the present invention provides an air conditioner, comprising: a shell, which defines an air outlet; and an air guide plate, which is any of the air guide plates described above.

[0019] Optionally, the air conditioner also includes: a second motor for driving the air guide plate body to rotate; a human sensing sensor for detecting whether a human body enters a preset indoor area; and a controller configured to control the second motor to drive the air guide plate body to rotate to a position where the wind avoids the human body when a human body enters the preset indoor area.

[0020] The air guide plate of the present invention comprises an air guide plate body and a plurality of rotatable inner guide plates. The inner guide plates and the air guide plate body jointly guide the airflow direction. In addition, the inner guide plates also play the role of splitting and interfering the airflow at the air outlet, so that the airflow blows into the room in a more dispersed and gentle manner, making the wind feel closer to natural wind, and achieving a comfortable air supply effect.

[0021] Furthermore, after the air guide plate body is rotated to a certain angle, the air guide direction can be further changed by rotating the inner guide plate, so that the air guide angle range of the air guide plate is larger.

[0022] Furthermore, when the air guide plate of the present invention and the air guide plate of the prior art are at the same opening (the same opening makes the air volume the same), the present invention can further adjust the wind direction by using the inner guide plate, so that the wind guide angle is larger. Therefore, when the air conditioner causes the air guide plate body to rise and blow air, the inner guide plate can play a role in guiding the wind upward. This eliminates the need to rotate the air guide plate body to an overly vertical state (i.e., a state close to closing the air outlet) to avoid a significant impact on the air volume.

[0023] Furthermore, the air conditioner of the present invention realizes the function of preventing direct blowing by setting a human presence sensor. When a human body enters a preset area indoors, the air deflector is controlled to rotate to avoid direct blowing of the wind on the human body, achieving the effect of preventing direct blowing and enhancing the comfort experience of the user.

[0031] The following will describe the air deflector and the air conditioner having the same according to embodiments of the present invention with reference to Figures 1 to 5 Among them, the orientation or positional relationship indicated by "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention 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 limitation of the present invention.

[0032] Figure 1 is a schematic structural diagram of an air deflector according to an embodiment of the present invention; Figure 2 is Figure 1 an enlarged view of part A of the structure shown; Figure 3 is Figure 1 a schematic cross-sectional view of the air deflector shown; Figure 4 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present invention.

[0033] As shown Figures 1 to 4 in the figure, the air deflector 50 of the embodiment of the present invention generally may include an air deflector body 51 and a plurality of inner deflectors 52, 53, 54. The air deflector body 51 is rotatably mounted at the air outlet 12 of the air conditioner housing 10 about an axis (x-axis) parallel to its own length direction, 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 an arc-shaped plate with a convex surface facing the outside of the air outlet 12 as a whole, or may also be other forms of plate structures for guiding the air flow direction of the air outlet 12. The plurality of inner deflectors 52, 53, 54 are arranged at intervals along the width direction of the air deflector body 51 on the inner side of the air deflector body 51, and their length directions are all parallel to the length direction of the air deflector 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 housing 10 is called the inner side. Each of the inner deflectors 52, 53, 54 is rotatably mounted on the air deflector body 51 about an axis parallel to its own length direction, so as to change the air flow direction on the inner side of the air deflector body 51 by rotating to different angles. The length direction of the air outlet 12, the air deflector body 51 and the inner deflectors 52, 53, 54 may be arranged in the horizontal direction.

[0034] In the embodiment of the present invention, when the air flow inside the housing 10 blows towards the air outlet 12 and flows through the surface of the air deflector body 51, it will be disturbed by the inner deflectors 52, 53, 54. Part of the air flow flows out along the outside of the inner deflectors 52, 53, 54, and part of the air flow flows out from the interval area between the inner deflectors 52, 53, 54 and the air deflector body 51, that is, the air flow is split and dispersed. After the air flow is dispersed by each of the inner deflectors 52, 53, 54, it will not blow towards the room concentratedly, the blowing force is also weakened, becoming softer, and the wind feeling is closer to natural wind, achieving the effect of comfortable air supply. The multi-layer air guiding structure of the air deflector can also avoid the condensation phenomenon at the air outlet during the refrigeration operation of the air conditioner.

[0035] In addition, in order to improve the air supply comfort, when the air conditioner is refrigerating, it is usually desired that the air deflector guides the cold air to blow out as vertically upward as possible. However, when the air deflector of the traditional air conditioner rotates to an 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 very small (the opening degree of the air deflector refers to the degree to which it opens 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 where the air outlet is located, the opening degree is 100%, and the air outlet is the smoothest), and the air deflector will seriously block the air outlet, and the air volume becomes very small. This limits the air guiding angle range of the air deflector. Especially when guiding the air vertically, it is difficult to take into account both the air guiding angle and the air volume.

[0036] In the embodiment of the present invention, after the air deflector body 51 rotates to a certain angle, the air guiding direction can still be further changed by rotating the inner deflectors 52, 53, and 54. This is how the embodiment of the present invention enables a larger air guiding angle range of the air deflector 50. Since the inner deflectors 52, 53, and 54 are relatively upper in position, it is beneficial to blow the air upward. Therefore, when the air conditioner operates in the cooling mode, it is not necessary to rotate the air deflector body 51 to a state too close to the vertical, so as to ensure that the air deflector 50 has a sufficiently large opening degree and avoid affecting the air volume. 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 deflectors, the air flow in each area in the width direction of the air deflector body 51 can be effectively guided( Figure 3 The arrows indicate the wind direction), undoubtedly strengthening the guiding effect on the air flow inside the air deflector body 51.

[0037] In some embodiments, such as Figure 1 and Figure 2 shown, the air deflector 50 may further include a plurality of connecting bars 57. Different parts in the length direction of each connecting bar 57 are respectively connected to an inner deflector 52, 53, or 54, so that when one inner deflector rotates, the inner deflector can drive other inner deflectors to rotate synchronously through the connecting bar 57. Optionally, the connecting bar 57 can be made of plastic, and the connecting parts thereof with the inner deflectors 52, 53, and 54 can be freely bent as the inner deflectors 52, 53, and 54 rotate, thus forming a connection relationship similar to a hinge without the need to provide a more complex shaft-hole structure. The plurality of connecting bars 57 are arranged along the length direction of the air deflector body 51. Of course, the connecting bars 57 may not be provided to independently adjust the angles of the inner deflectors 52, 53, and 54.

[0038] In some embodiments, the angles of the inner deflectors 52, 53, and 54 can be adjusted by manually rotating them. In other embodiments, such as Figure 2 shown, the air deflector 50 further includes at least one first motor 58. The first motor 58 is installed on the air deflector body 51, and each first motor 58 is used to drive one inner deflector to rotate. Shafts can be provided at both ends of the inner deflector, and the shafts are rotatably installed on the shaft seats provided at both ends of the air deflector body 51.

[0039] Such as Figure 1 shown, a plurality of mounting seats 515 arranged along the length direction of the air deflector body 51 are provided on the inner surface 511 of the air deflector body 51, and the mounting seats 515 are used to connect to the housing 10. For example Figure 4, there are as many mounting arms 70 provided on the housing 10 as the number of the mounting seats 515, and each mounting seat 515 is rotatably mounted on a mounting arm 70 (through a shaft-hole structure). In order to make room for each mounting seat 515, each of the inner guide plates 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 for the mounting seat 515. For example Figure 1 As shown, 4 mounting seats 515 can be provided and are arranged at equal intervals along the length direction of the air guide plate body 51. Among them, 2 mounting seats 515 are located at both ends of the air guide plate body 51 in the length direction. Each of the inner guide plates 52, 53, 54 includes 3 length segments.

[0040] As Figure 1 shown, the adjacent length segments of the inner guide plates 52, 54 equipped with the first motor 58 can be connected by a connecting shaft 55. In addition, a bearing seat 56 for mounting the connecting shaft 55 is provided on the inner surface 511 of the air guide plate body 51 to provide a more stable support for the inner guide plate. There is no direct connection structure between each length segment of the inner guide plate 53 not equipped with the first motor 58 and the air guide plate body 51 to simplify the structure of the air guide plate. For example Figure 1 As shown, the number of the plurality of inner guide plates is three, namely the inner guide plate 52, the inner guide plate 53 and the inner guide plate 54. Only the two inner guide plates 52, 54 at both ends in the width direction of the air guide plate body 51 are each equipped with a first motor 58. The middle inner guide plate 53 is not equipped with a first motor 58, has no direct connection structure with the air guide plate body 51, and there is no connecting shaft 55 between adjacent length segments, so as to make room for the mounting seat 515.

[0041] As Figure 3 shown, each length segment of each of the inner guide plates 52, 53, 54 is an arc-shaped plate with a straight side parallel to the length direction of the air guide plate body 51 and a convex surface facing the air guide plate body 51, so as to facilitate guiding the air in a direction closer to vertically upward during refrigeration.

[0042] An embodiment of the present invention also provides an air conditioner, which can be various terminal models of a wall-mounted machine, a cabinet machine or a central air conditioner. Hereinafter, a wall-mounted machine will be taken as an example for introduction.

[0043] As Figure 4 shown, generally, the air conditioner can include a housing 10 and the air guide plate 50 of any of the above embodiments. An air inlet 11 and an air outlet 12 are provided on the housing 10. The air guide plate body 51 of the air guide plate 50 is rotatably mounted on the housing 10 at the air outlet 12 to guide the air flow direction at the air outlet 12.

[0044] As Figure 4As shown, the air conditioner further includes an evaporator 20, a fan 30, an air duct 40, and a swing blade 60. The evaporator 20 is used to perform heat exchange with the air entering the housing 10 from the air inlet 11 to form heat exchange wind (specifically, cold wind during cooling and hot wind during heating). The inlet of the air duct 40 faces the evaporator 20, and the outlet is connected to 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 swing blade 60 is used to swing the wind left and right.

[0045] like Figure 4 As shown, the air outlet 12 can be located at the lower front part of the housing 10 and be a long rectangular shape extending in the horizontal direction. The air guide body 51 is a long rectangular shape matching the air outlet 12, and the rotation axis (x axis) of the air guide body 51 is parallel to the length direction of the air guide body 51.

[0046] Figure 5 is a schematic block diagram of an air conditioner according to an embodiment of the present invention. Figure 5 As shown, the air conditioner may include a second motor 59 , a human sensing sensor 80 , and a controller 90 .

[0047] The second motor 59 is used to directly drive the air deflector body 51 to rotate. The human sensing sensor 80 is used to detect whether a human body enters a preset indoor area. The preset indoor area can be a part of the indoor area that a human body can enter, such as a bed and its vicinity, or the entire indoor area. The human sensing sensor 80 can be an infrared sensor. After the human sensing sensor 80 detects that a person enters the preset area, it generates a human sensing signal and transmits it to the controller 90.

[0048] 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 sensing signal transmitted by the human sensing sensor 80, it controls the second motor 59 to operate, so that the air guide plate body 51 rotates to a position where the wind avoids the human body (for example, the upward blowing position or the downward blowing position). The controller 90 can also control the movement of the swing blade 60 to avoid the wind from the human body. In this way, the effect of preventing direct blowing can be achieved, and the user's comfort experience can be improved.

[0049] When the air conditioner is not in the anti-direct blowing mode, the controller 90 controls the rotation of the air guide plate body 51 and the swing blade 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.

[0050] At this point, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the disclosed content of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized to cover all such other variations or modifications.
