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 make the guiding effect of the air guide plate on the airflow adjustable.

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

[0008] An air guide plate body, which is used to be rotatably mounted at the air outlet of the air conditioner; and

[0009] At least one inner guide plate, each inner guide plate is installed on the air guide plate body at a distance from a side surface of the air guide plate body to guide the air flow direction together with the air guide plate body; and

[0010] The spacing distance between the inner guide plate and the air guide plate body is adjustable so as to change the guiding effect of the inner guide plate on the airflow.

[0011] Optionally, each inner guide plate is clamped to the air guide plate body, so that the spacing distance between the inner guide plate and the air guide plate body can be adjusted by changing the clamping position of the inner guide plate and the air guide plate body.

[0012] Optionally, the inner guide plate has a plurality of insert tubes extending toward the air guide plate body, and a plurality of slots arranged along the axial direction of the insert tubes are provided on the wall of each insert tube; the air guide plate body has a plurality of insert rods extending toward the inner guide plate, and each insert rod has a clamping protrusion; each insert rod is inserted into an insert tube and the clamping protrusion is clamped into one of the plurality of slots.

[0013] Optionally, the air guide plate body has a plurality of insert tubes extending toward the inner guide plate, and a plurality of slots arranged along the axial direction of the insert tube are provided on the wall of each insert tube; the inner guide plate has a plurality of insert rods extending toward the air guide plate body, and each insert rod has a clamping protrusion; each insert rod is inserted into an insert tube and the clamping protrusion is clamped into one of the plurality of slots.

[0014] Optionally, each inner guide plate is an arc-shaped plate with a straight side parallel to the rotation axis of the air guide plate body and a convex surface facing the air guide plate body.

[0015] Optionally, the surface of the air deflector body facing the inside of the air outlet when the air outlet is closed is the inner surface; the number of the at least one inner guide plate is one and is installed on the inner surface of the air deflector body.

[0016] Optionally, in a direction parallel to the rotation axis of the air guide plate body, two ends of the inner guide plate are flush with two ends of the air guide plate body.

[0017] Optionally, when guiding air, the end of the air guide plate body facing the inner side of the air outlet is the windward end, and the end facing the outer side of the air outlet is the air outlet end; each inner guide plate is arranged in the area close to the air outlet end of the air guide plate body.

[0018] On the other hand, the present invention also provides an air conditioner, comprising:

[0019] a housing defining an air outlet; and

[0020] According to any of the above air deflector items, the air deflector body is rotatably installed at the air outlet.

[0021] Optionally, the air conditioner also includes: a 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 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.

[0022] The air guide plate of the present invention comprises an air guide plate body and an inner guide plate spaced apart from a side surface of the air guide plate body. The inner guide plate and the air guide plate body jointly guide the airflow direction. In addition, the inner guide plate also plays a role in splitting and interfering with 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. At the same time, the double-layer air guide structure of the air guide plate can also avoid condensation at the air outlet when the air conditioner is in cooling operation.

[0023] Furthermore, the air guide plate of the present invention can change the guiding effect of the inner guide plate on the airflow by adjusting the spacing distance between the inner guide plate and the air guide plate body.

[0024] Furthermore, the air guide plate of the present invention installs an inner guide plate on the inner surface of the air guide plate body. When the air conditioner cools the air guide plate body upward to blow air, due to the presence of the inner guide plate, there is no 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 output.

[0025] Furthermore, in the air guide plate of the present invention, the inner guide plate is arranged in an area close to the air outlet end of the air guide plate body, so as to enhance the air guiding function of the inner guide plate and guide the airflow to a preset direction, while avoiding the inner guide plate being too wide to increase the air outlet resistance.

[0026] Furthermore, the air conditioner of the present invention realizes the anti-direct blowing function by setting a human sensing sensor. When a person enters the preset area indoors, the air guide plate is controlled to rotate to prevent the wind from blowing directly on the person, thereby achieving the anti-direct blowing effect and improving the user's comfort experience.

[0036] Refer to the following Figures 1 to 7 To describe the air guide plate of the embodiment of the present invention and the air conditioner having the same. The directions or positional relationships indicated by "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0037] An embodiment of the present invention provides an air guide plate. Figure 1 is a schematic structural diagram of an air guide plate according to an embodiment of the present invention; Figure 2 yes Figure 1 An enlarged view of the air guide plate at position K is shown; Figure 3 yes Figure 1 An exploded schematic diagram of the air guide plate shown; Figure 4 yes Figure 2 A schematic diagram of the end structure of the inner guide plate in the air guide plate shown.

[0038] like Figures 1 to 4 As shown, the air guide plate 50 may generally include an air guide plate body 51 and at least one inner guide plate 52. The air guide plate body 51 is used to be rotatably mounted at the air outlet 12 of the air conditioner, and its rotation axis is the x-axis indicated in the figure. The air guide plate 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 air outlet direction of the air outlet 12 so that the wind blows to different areas of the room. Each inner guide plate 52 is mounted on the air guide plate body 51 and is spaced from a side surface of the air guide plate body 51 to guide the airflow direction of the air outlet 12 together with the air guide plate body 51.

[0039] Figure 1 Arrows are used to indicate wind direction, such as Figure 1 As shown, when the airflow flows through the surface of the air guide plate body 51, it will be disturbed by the inner guide plate 52. Part of the airflow flows out along the outer side of the inner guide plate 52, and part of the airflow flows out from the interval area between the inner guide plate 52 and the air guide plate body 51, that is, the airflow is split and dispersed. After the airflow is dispersed by the inner guide plate 52, it will not be concentrated and blown into the room. The blowing force will also be weakened, becoming softer, and the wind feeling will be closer to natural wind, achieving a comfortable air supply effect. The double-layer air guide structure of the air guide plate 50 can also avoid condensation at the air outlet 12 when the air conditioner is in cooling operation.

[0040] Figure 5 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present invention; Figure 6 yes Figure 5 The diagram shows the state of the air conditioner after the distance between the inner guide plate and the air guide plate body is changed.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, the embodiment of the present invention also makes the spacing distance between the inner guide plate 52 and the air guide plate body 51 adjustable so as to change the guiding effect of the inner guide plate 52 on the airflow.

[0042] 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 on splitting and dispersing the airflow will be weakened, but the wind speed and air volume of the air outlet 12 are less affected by the inner guide plate 52. Therefore, if the user pursues a higher cooling / heating speed (which means 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, referring to Figure 5 .

[0043] When the distance between the inner guide plate 52 and the air guide plate body 51 is large, the distance between the inner guide plate 52 and the air guide plate body 51 is relatively far, and the effect of the inner guide plate 52 splitting and dispersing the airflow will be stronger, but the wind speed and air volume of the air outlet 12 are more affected by the inner guide plate 52. Therefore, if the user does not require much cooling / heating speed, but pursues more comfort of air supply, the distance between the inner guide plate 52 and the air guide plate body 51 can be adjusted to be larger, referring to Figure 6 .

[0044] like Figure 1 As shown, the surface 511 of the air deflector body 51 facing the inside of the air outlet 12 when the air outlet 12 is closed is set as the inner surface, and the surface 512 facing the indoor room is set as the outer surface. In order not to affect the appearance of the air deflector body 51, the inner guide plate may not be set on the outer surface of the air deflector body 51. That is, it is preferred that the number of the at least one inner guide plate 52 is one, and the inner guide plate 52 is installed on the inner surface of the air deflector body 51.

[0045] Of course, in some alternative embodiments, multiple inner guide plates may be provided on the inner surface of the air guide body 51, so that the multiple inner guide plates are arranged at intervals along the length direction of the air guide body 51 or arranged in other ways. Alternatively, multiple inner guide plates may also be provided on the outer surface of the air guide body 51. These embodiments will not be described in detail herein.

[0046] In order to make the air 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 aligned with the two ends of the air guide plate body 51 (that is, the inner guide plate 52 and the air guide plate body 51 have the same length), as shown in FIG. Figure 1 .

[0047] In order to improve the comfort of air supply, the prior art hopes that the air guide plate guides the cold air to blow out vertically upwards as much as possible during air conditioning cooling. However, when the air guide plate is close to the limit of the upward air guide angle, the angle between the air guide plate and the plane where the air outlet is located is too small, that is, the opening is very small, the air guide plate will seriously block the air outlet, and the air volume becomes very small. This limits the air guide angle range of the air guide plate. Especially when the air is guided vertically, it is difficult to take into account both the air guide angle and the air volume.

[0048] In this embodiment, when the air guide plate guides the wind upward, the inner guide plate 52 disposed on the inner surface of the air guide plate body 51 is relatively high, which is conducive to blowing the wind upward. When the air conditioner is in cooling operation, it is not necessary to rotate the air guide plate body 51 to a state that is too close to the vertical position, so as to ensure that the air guide plate has a sufficiently large opening to avoid affecting the air volume. That is, this embodiment takes into account both the air supply angle and the air volume.

[0049] like Figure 1 As shown, the inner guide plate 52 is preferably a curved plate with a straight edge parallel to the rotation axis x of the air guide plate body 51 and a convex surface facing the air guide plate body 51, so as to facilitate guiding the wind in a more vertical upward direction during cooling.

[0050] like Figure 1 As shown, when the air guide plate 50 guides the air, the air flow inside the air conditioner first passes through one end (end B) of the air guide plate body 51 facing the inner side of the air outlet 12, and after being guided by the air guide plate body 51, it blows into the room through one end (end A) facing the outer side of the air outlet 12. Therefore, the end B is defined as the windward end, and the end A is the wind outlet end. The inner guide plate 52 can be arranged in the area close to the wind outlet end of the air guide plate body 51, so that the air flow is guided by the part of the air guide plate body 51 close to the windward end, and then blows toward the inner guide plate 52. That is, the inner guide plate 52 is disturbed at the end of the air guide cycle of the air guide plate body 51, so that the air flow after the disturbance can be blown into the room faster. At the same time, it is preferred that the ratio of the width of the inner guide plate 52 to the width of the air guide plate body 51 is between 1 / 3 and 1 / 2, so as to enhance the wind guiding function of the inner guide plate 52 and facilitate guiding the air flow to the preset direction. It can also prevent the width of the inner guide plate 52 from being too wide, thereby increasing the wind resistance.

[0051] The connection method between the inner guide plate 52 and the air guide plate body 51 is described below.

[0052] For example, each inner guide plate 52 is snap-connected to the air guide plate body 51 , so that the spacing distance between the inner guide plate 52 and the air guide plate body 51 can be adjusted by changing the snap-connecting position of the inner guide plate 52 and the air guide plate body 51 .

[0053] Specific as Figures 1 to 4As shown, the inner guide plate 52 may be provided with a plurality of insert tubes 522 extending toward the air guide plate body 51, and a plurality of bayonet holes 523, 524, 525 arranged along the axial direction of the insert tube 522 may be provided on the wall of each insert tube 522. Matchingly, the air guide plate body 51 may be provided with a plurality of insert rods 513 extending toward the inner guide plate 52, and each insert rod 513 may have a retaining protrusion 514 (the number may be one or more). The number of the insert rods 513 is the same as the number of the insert tubes 522, and the positions are arranged one by one. When installing the inner guide plate 52, each insert rod 513 is inserted into the insert tube 522 through the opening 529 of an insert tube 522, and then a retaining protrusion 514 is inserted into one of the bayonet holes 523, 524, 525, so that the insert rod 513 and the insert tube 522 are fully engaged. The number of the inserting tubes 522 is preferably 4, so that the 4 inserting tubes 522 are respectively arranged at the four corners of the inner guide plate 52. Correspondingly, the number of the inserting rods 513 is also preferably 4, and the 4 inserting rods 513 are respectively arranged at the four corners of the air guide plate body 51.

[0054] For example, in the embodiment shown in Figure 4, three bayonet holes 523, 524, and 525 are arranged along the length direction of the insert tube 522, that is, the distance between the inner guide plate 52 and the air guide plate body 51 has three adjustment gears. When the clamping protrusion 514 is clamped into the bayonet hole 523, the distance between the inner guide plate 52 and the air guide plate body 51 is the smallest. When the clamping protrusion 514 is clamped into the bayonet hole 525, the distance between the inner guide plate 52 and the air guide plate body 51 is the largest. When the clamping protrusion 514 is clamped into the bayonet hole 525 (refer to Figure 4 ), the distance between the inner guide plate 52 and the air guide plate body 51 is at an intermediate position.

[0055] Of course, in some alternative embodiments, the air guide body 51 may also have a plurality of inserting tubes extending toward the inner guide, and a plurality of bayonet holes arranged along the axial direction of the inserting tube are provided on the wall of each inserting tube. The inner guide may have a plurality of inserting rods extending toward the air guide body 51, and each inserting rod may have a retaining protrusion; each inserting rod may be inserted into an inserting tube and the retaining protrusion may be retained in one of the plurality of bayonet holes. The details will not be repeated.

[0056] In this embodiment, the inner guide plate is installed on the air guide plate body by a snap-fitting method, and the installation and removal process is very simple, which is convenient for users to operate.

[0057] Of course, other methods can also be used to connect the inner guide plate and the air deflector body. For example, the air deflector body has a plurality of first mounting rods extending toward the inner guide plate, and the first mounting rods are provided with a plurality of threaded holes arranged equidistantly along the length direction thereof. The inner guide plate has a plurality of second mounting rods extending toward the air deflector body, and the second mounting rods are provided with a plurality of through holes arranged equidistantly along the length direction thereof. At least one threaded hole of each first mounting rod is matched with a through hole of a second mounting rod, and the first mounting rod and the second mounting rod are connected by screws. Furthermore, the fastening position of the first mounting rod and the second mounting rod can be changed by making the threaded holes correspond to different through holes, thereby changing the spacing distance between the inner guide plate and the air deflector body.

[0058] The embodiment of the present invention further provides an air conditioner. The air conditioner can be a wall-mounted unit, a cabinet unit, or various terminal models of a central air conditioner. The following is an introduction taking a wall-mounted unit as an example.

[0059] like Figure 5 As shown, the air conditioner generally includes a housing 10, which is provided with an air inlet 11, an air outlet 12 and an air guide plate 50 of any of the above embodiments. The air guide plate body 51 of the air guide plate 50 is rotatably mounted at the air outlet 12 to achieve the various functions and effects introduced in the above embodiments.

[0060] like Figure 5 As shown, the air conditioner also 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 air during cooling and hot air 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 to flow from the evaporator 20 to the air outlet 12. The housing 10 is provided with a plurality of first mounting arms 70 at the air outlet 12, and a plurality of second mounting arms 515 matching the plurality of first mounting arms 70 are provided on the air guide plate body 51, and the second mounting arms 515 are rotatably mounted on the corresponding first mounting arms 70. The swing blade 60 is used for left and right swinging.

[0061] like Figure 5 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. The rotation axis (x axis) of the air guide body 51 is parallel to the length direction of the air guide body 51.

[0062] Figure 7 is a schematic block diagram of an air conditioner according to an embodiment of the present invention. Figure 7 As shown, the air conditioner may include a motor 53 , a human sensing sensor 80 , and a controller 90 .

[0063] The motor 53 is used to drive the air deflector body 51 to rotate around its rotation axis. The human sensing sensor 80 is installed on the housing 10 and is used to detect whether a human body enters a preset area indoors. The 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 has entered the preset area, a human sensing signal is generated and transmitted to the controller 90.

[0064] 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, the controller 90 controls the motor 53 to drive the air guide plate body 51 to rotate to a position (such as an upward blowing position or a downward blowing position) so that the wind avoids the human body. The controller 90 can also control the angle 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.

[0065] When the air conditioner is not in the anti-direct blowing mode, the controller 90 controls the rotation of the air guide plate 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.

[0066] At this point, those skilled in the art should recognize that, although multiple 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 based on the content disclosed in 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 as covering all these other variations or modifications.
