Description
Technical Field
The invention relates to the technical field of air conditioning, in particular to an air deflector and an air conditioner with the same.
Background
The wind deflector of the air conditioner directly affects the parameters such as wind direction, air quantity, wind speed and the like of the air outlet of the air conditioner, and plays a very important role in the air supply process of the air conditioner.
However, after years of development in the air conditioning industry, innovative improvements to the air deflector are not uncommon. At present, whether a high-end air conditioner or a medium-end air conditioner is adopted, the adopted air deflector is still a strip-shaped arc plate which can be rotatably arranged on the shell around an axis. The single structure and function of the air deflector also directly restrict the improvement of the air supply performance and the expansion of the air supply mode of the air conditioner.
Disclosure of Invention
The invention aims to provide an air deflector which is novel in structure and beneficial to expanding an air supply mode of an air conditioner.
The invention further aims to expand the air guiding range of the air guiding plate, so that the air conditioner can give consideration to the air outlet angle and the air quantity.
Another object of the present invention is to provide an air conditioner having the above-mentioned air guide plate.
In one aspect, the present invention provides an air deflector comprising:
an air deflector body; and
one end of each telescopic arm is connected with the air deflector body, and the other end of each telescopic arm is rotatably arranged on the shell of the air conditioner so that the telescopic arm drives the air deflector body to rotate, and therefore the air flow direction at the air outlet of the air conditioner is guided; and is also provided with
The distance between the two ends of each telescopic arm is adjustable, so that the distance between the air deflector body and the rotating axis of the air deflector body is adjustable.
Optionally, each telescoping arm comprises: the fixed part is fixed at the first end of the air deflector body, the second end of the fixed part is far away from the air deflector body, and the end surface of the fixed part is internally provided with an inserting hole; and the first end of the connecting part is used for being rotationally connected with the shell, and the second end of the connecting part is telescopically inserted into the jack, so that the distance between the first end of the connecting part and the first end of the fixing part is adjustable.
Optionally, the fixing portion of at least one telescopic arm is provided with a first motor and a gear driven by the first motor, and the connecting portion is provided with a rack meshed with the gear, so that the first motor drives the connecting portion to stretch and retract relative to the fixing portion through the gear and the rack.
Optionally, the first motor and the gear are mounted outside the jack; the rack is connected with the connecting part through an intermediate plate; and the side wall of the jack is provided with a yielding port so as to allow the middle plate to be inserted into the yielding port when the connecting part is inserted into the jack, so that the rack is exposed out of the jack.
Alternatively, the insertion holes and the connecting parts are flat structures, and the thickness direction of each flat structure is parallel to the rotation axis direction of the air deflector body.
Optionally, the air deflector further comprises: the branch plate starts from the inner side surface of the air deflector body, extends along the airflow flowing direction and gradually away from the air deflector body, and guides the airflow blowing direction at the air outlet together with the air deflector body.
Optionally, one end of the air deflector body facing the inner side of the air outlet is a windward end when the air is guided, and one end facing the outer side of the air outlet is an air outlet end; the branching plate is arranged in a windward end area far away from the air deflector body.
Optionally, the distance between the starting end and the tail end of the branching plate is smaller than the distance between the starting end of the branching plate and the air outlet end of the air deflector body.
In another aspect, the present invention provides an air conditioner, comprising:
a housing defining an air outlet; and
the air deflector is any one of the air deflectors, wherein at least one telescopic arm is rotatably arranged on the shell, so that the telescopic arm drives the air deflector body to rotate, and the air flow direction at the air outlet of the air conditioner is guided.
Optionally, the air conditioner further comprises a second motor for driving one telescopic arm to rotate; the human sensor is used for detecting whether a human body enters an indoor preset area; and the controller is configured to control the second motor to operate when a human body enters the indoor preset area, so that the air deflector body rotates to a position where wind avoids the human body.
The air deflector is rotatably arranged on the air conditioner shell through the telescopic arm, and the distance between the two ends of the telescopic arm is adjustable, so that the distance between the air deflector body and the rotating axis of the air deflector body is adjustable. After the air conditioner adopts the air deflector, various air supply modes can be expanded. For example, when the air outlet is closed by the air deflector body, the telescopic arm is extended to enable the air deflector body to be horizontally far away from the air outlet, so that a square annular air outlet area is formed between the edge of the air outlet and the edge of the air deflector body. Or when the air deflector body guides air, the telescopic arm is extended to enable the air deflector to be far away from the air outlet, so that the air supply distance is increased, and the air is guided to a farther area.
Further, the gravity and the air flow pressure of the air deflector are all applied to the fixing part of the telescopic arm, and then are applied to the connecting part through the fixing part. In order to ensure that the connection between the fixing part and the connecting part is more stable and smoother, and avoid the deformation caused by uneven stress on the contact surfaces of the fixing part and the connecting part, the invention particularly ensures that the fixing part jack and the connecting part are of flat structures with the thickness direction parallel to the rotation axis direction of the air deflector body, the contact area of the fixing part jack and the connecting part is larger, and when the torsion trend is generated by uneven stress of the air deflector body, the larger contact area (namely, larger stress area) can bear larger pressure so as to resist the torsion trend of the air deflector body.
Further, in the air deflector, the branch plate extends out of the surface of the air deflector body, so that the original air guiding direction of the air deflector body is changed by the branch plate, and the air guiding angle range of the air deflector is enlarged. When the air deflectors are at the same opening degree, compared with the prior art, the air quantity is basically the same, but the air guiding angle is larger.
Furthermore, in the air deflector, the distance between the starting end and the tail end of the branch plate is smaller than the distance between the starting end of the branch plate and the air outlet end of the air deflector body, so that the extension size of the branch plate from the air deflector body is limited, the size of the branch plate does not exceed the air outlet end of the air deflector body, and the influence of the overlarge branch plate on the air outlet quantity of the air outlet is avoided.
Furthermore, the air conditioner disclosed by the invention realizes the direct blowing prevention function by arranging the human sensor. When a human body enters an indoor preset area, the air deflector is controlled to rotate so as to avoid the wind from directly blowing the human body, the effect of preventing direct blowing is achieved, and the comfort level experience of a user is improved. The above, as well as additional objectives, advantages, and features of the present invention will become apparent to those skilled in the art from the following detailed description of a specific embodiment of the present invention when read in conjunction with the accompanying drawings.

Detailed Description
The following describes an air deflector and an air conditioner having the same according to an embodiment of the present invention with reference to fig. 1 to 6. Where the terms "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "transverse", etc., refer to an orientation or positional relationship based on that shown in the drawings, this is merely for convenience in describing the invention and to simplify the description, and does not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.
FIG. 1 is a schematic block diagram of an air deflection in accordance with one embodiment of the present invention; FIG. 2 is a schematic cross-sectional view of the air deflection shown in FIG. 1; FIG. 3 is a schematic exploded view of the end structure of the air deflection shown in FIG. 1; fig. 4 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present invention.
As shown in fig. 1-4, the air deflection 50 of embodiments of the present invention may generally include an air deflection body 51 and at least one telescoping arm 55. The air deflector body 51 is in an arc plate shape with a convex surface facing the outside of the air outlet 12, or in other plate structures for guiding the air flow direction of the air outlet 12. The deflector body 51 is connected to the air conditioner case 10 by a telescopic arm 55. Specifically, one end of the telescopic arm 55 is connected to the air deflector body 51, and may be integrally connected or detachably fixed. The other end of the telescopic arm 55 is rotatably mounted to the housing 10, the axis of rotation being indicated by the x-axis in the figure. When driven to rotate, the telescopic arm 55 can drive the air deflector body 51 to rotate. The telescoping arm 55 may be provided with a shaft 551, the shaft 551 being inserted into an opening in the housing mounting arm 70 to provide a rotational connection. The distance between the two ends of each telescopic arm 55 is adjustable, so that the distance between the air deflector body 51 and the rotation axis thereof (the distance is denoted as s in fig. 2) is adjustable.
After the air conditioner adopts the air deflector 50 of the embodiment of the invention, a plurality of air supply modes can be expanded. For example, when the air guide plate body 51 closes the air outlet, the telescopic arm 55 is extended to make the air guide plate body 51 move away from the air outlet 12 in a translational manner, so that a square annular air outlet area is formed between the edge of the air outlet 12 and the edge of the air guide plate body 51. Alternatively, when the air guide plate body 51 guides the air, the telescopic arm 55 is extended to move the air guide plate body 51 farther from the air outlet 12, so that the air supply distance is increased and the air is guided to a farther area. For example, the distance between the ends of the telescopic arm 55 in fig. 5 is set larger than that in fig. 4, and the air blowing distance is longer. In the case that the air guiding angle of the air guiding plate body 51 is not changed, the air outlet area of the air outlet 12 can be changed by adjusting the space s between the air guiding plate body 51 and the rotation axis thereof. When the distance is increased, the air deflector body 51 is further away from the air outlet 12, so that the air outlet area of the air outlet 12 is larger, and the air quantity is larger.
An alternative construction of the telescopic arm 55 is described below with reference to fig. 1 to 3. Each telescoping arm 55 includes a fixed portion 554 and a connecting portion 552. The fixing portion 554 has a first end fixed to the air deflector body 51, a second end remote from the air deflector body 51, and an insertion hole 5541 formed in an end surface thereof inward (inward means a direction toward the air deflector body 51). The first end of the connection portion 552 is adapted to be rotatably connected to the housing 10, and the second end is telescopically inserted into the socket 5541 such that the connection portion 552 is slidably translatable (slidably translatable in a direction parallel to the y-axis) within the socket 5541. So that the distance between the first end of the connection portion 552 and the first end of the fixing portion 554 (corresponding to the distance between both ends of the telescopic arm 55 described above) is adjusted by the movement of the connection portion 552.
The gravity and the air flow pressure of the air deflector 50 are all applied to the fixing portion 554 of the telescopic arm 55, and are then applied to the connection portion 552 through the fixing portion 554. In order to make the connection between the fixing portion 554 and the connecting portion 552 more stable and smooth, and avoid the deformation caused by uneven stress on the contact surface of the fixing portion 554 and the connecting portion 552 from increasing friction and noise, the fixing portion 554 and the connecting portion 552 are in flat structures (see fig. 1) with thickness directions parallel to the rotation axis direction (x axis) of the air deflector body 51, so that the contact area between the fixing portion 554 and the connecting portion 552 is larger, and when the air deflector body 51 is stressed unevenly, the larger contact area (i.e. larger stress area) can bear larger pressure to resist the torsion trend of the air deflector body 51.
The number of the telescopic arms 55 may be one or more, preferably a plurality, so that the force of the air deflector 50 is dispersed to the plurality of telescopic arms 55, and the air deflector 50 is more stable. For example, as shown in fig. 1, 4 telescopic arms 55 are provided, so that the 4 telescopic arms 55 are uniformly distributed along a direction parallel to the rotation axis of the air deflector body 51, and the stress of each telescopic arm 55 is more uniform.
In some embodiments, as shown in fig. 3, a first motor 557 and a gear 555 driven by the first motor 557 are provided on the fixing portion 554 of at least one telescopic arm 55, and a rack 553 meshed with the gear 555 is provided on the connecting portion 552 to form a rack-and-pinion driving mechanism, so that the connecting portion 552 is driven to telescope relative to the fixing portion 554 by the first motor 557 through the gear 555 and the rack 553. When one telescopic arm 55 is provided, the aforementioned rack and pinion driving mechanism is provided on the telescopic arm 55. When a plurality of telescopic arms 55 are provided, only one telescopic arm 55 or a plurality of telescopic arms 55 may be provided with the rack and pinion driving mechanism. It is preferable that a rack and pinion drive mechanism is provided to two telescopic arms 55 located at both ends of the deflector body 51.
As shown in fig. 3, in some embodiments, gear 555 is mounted outside of receptacle 5541. The rack 553 and the connecting portion 552 are connected by an intermediate plate 556 (the three may be integrally formed as a single piece). The sidewall of the jack 5541 is provided with a relief opening 5542. When the connection portion 552 is inserted into the insertion hole 5541, the intermediate plate 556 is inserted into the relief hole 5542 so that the rack 553 is exposed outside the insertion hole 5541.
Of course, in some alternative embodiments, the connection portion 552 may also be manually operated to perform telescopic movement, and the specific structure will not be described again.
In some embodiments, as shown in fig. 1 and 2, the deflector 50 may also include a branching plate 52. The branching plate 52 extends from the surface of the air deflector body 51 in the airflow direction of the air outlet 12 and gradually away from the air deflector body 51. When the air deflector body 51 is in a state of opening the air outlet 12 (i.e., in an air guiding state), the air flow is blown out from the inside of the air outlet 12 into the room. Accordingly, the branching plate 52 extends from the start end (C end) toward the indoor direction, and gradually moves away from the deflector body 51 during the extension, to the end (D end). It can be further understood that, when the air deflector body 51 is in the air guiding state, the branching plate 52 extends from the surface of the air deflector body 51 and clamps a preset acute angle with the surface of the air deflector body 51, and the inclined direction faces the outside of the air outlet 12. The air deflector body 51 and the branching plate 52 guide the air flow blowing direction at the air outlet 12 together.
In order to improve air supply comfort, when the air conditioner is used for refrigerating, the air deflector is expected to guide cold air to be blown out vertically upwards as much as possible; in the air conditioning, it is desirable that the air deflector guides the hot air to blow out as vertically downward as possible. However, when the air deflector approaches the air guiding angle of the upper limit and the lower limit, the included angle between the air deflector and the plane of the air outlet is too small, namely the opening degree is very small (the opening degree of the air deflector refers to the opening degree of the air outlet, and when the air deflector completely closes the air outlet, the opening degree is zero, when the surface of the air deflector is nearly vertical to the surface of the air outlet, the opening degree is 100%, the air outlet is the most smooth), the air deflector seriously shields the air outlet, and the air quantity is very small. This limits the wind deflection angle range of the deflector. Particularly, when vertical air guiding is performed, the air guiding angle and the air quantity are difficult to be simultaneously achieved.
In the embodiment of the present invention, the branch plate 52 changes the original air guiding direction of the air guiding plate body 51. For example, when the air guide plate 50 of the present embodiment is applied to the air conditioner shown in fig. 4, the air guide angle (the angle between the air flow direction on the upper side of the air guide plate and the horizontal plane) of the air guide plate 50 is a. Assuming the branching plate 52 is removed and becomes a prior art deflector, the air outlet angle will obviously be less than a. If the air guiding angle of the air guiding plate in the prior art is required to reach a, the air guiding plate needs to be continuously rotated upwards for a certain angle. However, the opening degree is reduced, and the air outlet of the air outlet 12 is blocked. It can be seen that the air deflection 50 of the present invention has a greater air deflection angle than prior art air deflection at the same opening. In summary, the wind deflector of the present invention expands the angular range of the wind deflector by adding the branching plate 52.
When the air conditioner operates in the cold air avoiding mode, the air deflector body 51 is controlled to rotate to an upward blowing angle shown in fig. 4, and the "upturned" branch plate 52 guides the cold air to blow out in a direction closer to the vertical upward direction. Further, the air guide plate body 51 does not need to be rotated so far upward that the opening degree is too small, so that the air volume of the air outlet 12 is not excessively affected. It can be seen that the air deflector 50 of the present embodiment can achieve both air deflection angle and air volume.
In the direction parallel to the rotation axis of the air deflector body 51, it is preferable to make both ends of the branching plate 52 flush with both ends of the air deflector body 51 so that the span thereof is larger, and the air guiding effect is improved.
As shown in fig. 1 and 2, when the air guide plate 50 guides air, the air flow inside the air conditioner is guided by the air guide plate body 51 toward one end (end B) of the air outlet 12, and then is blown into a room through one end (end a) of the air guide plate body 51 toward the outside of the air outlet 12. Therefore, the end B is defined as a windward end, and the end A is defined as an air outlet end. Part of the air flow is blown out from the windward end of the air deflector body 51 through the inner surface of the air deflector body 51, through the start end (C end) of the branching plate 52, along the surface of the branching plate 52 to the end (D end) of the branching plate 52.
The branching plate 52 may be disposed at a position away from the windward end of the air deflector body 51 so that the distance (BD spacing) between the distal end of the branching plate 52 and the windward end of the air deflector body 51 is longer and the guiding effect on the air flow is stronger.
The surface formed from the windward end of the deflector body 51 to the end of the branching plate 52 can be made smooth to reduce the flow loss of the air flow. It can be further made into a smooth concave surface to be more beneficial to wind guiding upwards.
As shown in fig. 1 and 2, the distance between the starting end and the end of the branching plate 52 can be smaller than the distance between the starting end of the branching plate 52 and the air outlet end of the air deflector body 51, so that the end of the branching plate 52 does not exceed the air outlet end of the air deflector body 51, and the excessive branching plate 52 can be prevented from influencing the air volume of the air outlet 12.
The embodiment of the invention also provides an air conditioner. It can be a wall-mounted machine, a cabinet machine or various terminal machine types of a central air conditioner. The following description will be made by taking a wall-mounted machine as an example.
As shown in fig. 4, the air conditioner may generally include a housing 10 and an air deflection 50 of any of the embodiments described above. The shell 10 is provided with an air inlet 11 and an air outlet 12. At least one telescopic arm 55 of the air deflector 50 is rotatably mounted on the housing 10 at the air outlet 12 to rotate the air deflector body 51 by the telescopic arm 55, thereby guiding the air flow direction at the air outlet 12 of the air conditioner. And has various functions and effects described in the above embodiments. For example, the housing 10 is provided with the same number of mounting arms 70 as the number of telescopic arms 55, each telescopic arm 55 being mounted on one mounting arm 70.
As shown in fig. 4, the air conditioner further includes an evaporator 20, a fan 30, an air duct 40, and a swing blade 60. The evaporator 20 is configured to exchange heat with air entering the housing 10 from the air inlet 11 to form heat exchange air (specifically, cool air during cooling and hot air during heating). The inlet of the air duct 40 faces the evaporator 20, and the outlet is communicated with the air outlet 12. The fan 30 may be a cross-flow fan disposed at the inlet of the air duct 40 to facilitate air flow from the evaporator 20 to the air outlet 12. The swing blade 60 is used for swinging wind left and right.
As shown in fig. 4, the air outlet 12 may be located at a lower portion of the front side of the housing 10 and have a long rectangular shape extending in a horizontal direction. The air deflector body 51 is formed in a rectangular shape matching with the air outlet 12. And the rotation axis (x axis) of the air deflector body 51 is parallel to the length direction of the air deflector body 51.
As shown in fig. 4, a portion of the housing 10 adjacent to the top edge of the air outlet 12 may be recessed inwardly to form a relief recess 13. When the air deflector body 51 is in a position for closing the air outlet 12, the end of the air deflector body is positioned in the abdication concave portion 13, so that the outer surface of the air deflector 50 is flush with the outer surface (the portion not provided with the abdication concave portion) of the housing 10.
When the air deflector in the prior art closes the air outlet, the top end of the air deflector is basically aligned with the top edge of the air outlet so as to close the top edge of the air outlet just. This design effectively limits the size of the air deflector and does not allow for wider designs of the air deflector. In this embodiment, the air deflector body 51 is widened, and when the air outlet 12 is closed, the widened portion is located in the abdication recess 13 of the housing 10, so that the air conditioner is prevented from being unsightly due to the fact that the air deflector body 51 is directly lapped on the outer side of the surface of the housing 10.
More importantly, the widening design of the deflector body 51 lengthens its air guiding stroke, facilitating the guiding of the air flow to a predetermined direction. In addition, the air deflector body 51 has larger contact area with the shell 10 in the yielding concave part 13, improves sealing performance, and avoids condensation of water vapor in indoor air when the condensation occurs due to leakage of cold air, even dripping water when the condensation is larger.
Fig. 6 is a schematic block diagram of an air conditioner according to an embodiment of the present invention. In some embodiments, as shown in fig. 6, the air conditioner may include a second motor 53, a human sensor 80, and a controller 90.
The second motor 53 is used for directly driving one telescopic arm 55 to rotate so as to drive the air deflector body 51 to rotate. The human sensor 80 is used to detect whether a human body enters a preset indoor area. The area may be a partial area of the room where a person is able to enter, such as a bed and its vicinity, or may be the entire area of the room. The human sensor 80 may be an infrared sensor. After the human sensor 80 detects that a person enters the preset area, a human sensing signal is formed and transmitted to the controller 90.
The user may select whether the air conditioner enters the anti-direct blowing mode. When the air conditioner is in the anti-direct blowing mode, the controller 90 receives the human body sensing signal transmitted by the human body sensor 80 and then controls the second motor 53 to operate, so that the air deflector body 51 rotates to a position (for example, an up blowing position or a down blowing position) where wind avoids the human body. The controller 90 may also be configured to control the movement of the swing blade 60 and the first motor 557 to keep the wind away from the human body. Therefore, the effect of direct blowing prevention can be achieved, and the comfort level experience of a user is improved.
When the air conditioner is not in the direct blowing prevention mode, the controller 90 controls the rotation of the deflector body 51 and the swing blades 60 according to other control signals transmitted from a user through a remote controller or other communication terminals, or according to a preset operation mode of the air conditioner.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
