Description

Air deflector and embedded air conditioner

Technical Field

The application relates to the technical field of air conditioners, for example to an air deflector and an embedded air conditioner.

Background

As shown in fig. 1, in the conventional built-in air conditioner 200, an air inlet 210 and an air outlet 220 are formed at the lower side of a panel, the air inlet 210 is formed at the center, and the air outlet 220 is formed at the periphery of the panel. And under the condition of no air deflector, the air conditioner blows air downwards. In order to ensure that air conditioning wind does not blow directly, the air deflector is required to be arranged to adjust the air outlet angle of the air conditioning wind, and the air flow angle is unstable due to the fact that the air deflector is manually adjusted in many traditional embedding machines. Especially, in hot summer, when the embedded air conditioner is installed in an office, people sitting under the air conditioner can be directly blown by cold air of the air conditioner all the time, and people who are not under the air conditioner can not receive the cold air. Cold air is not directly blown, and falling to the ground of warm air is two main problems which need to be solved by the embedded air conditioner. At present, the problem of cold air direct blowing or the problem of falling of warm air is generally avoided by controlling the air outlet angle.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: the air outlet angle is limited, so that the horizontal included angle between the air deflector and the horizontal plane is limited, and the air outlet quantity of the air conditioner is influenced.

Disclosure of Invention

The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed embodiments. This summary is not an extensive overview nor is intended to identify key/critical elements or to delineate the scope of such embodiments but rather as a prelude to the more detailed description that is presented later.

The embodiment of the disclosure provides an air deflector and an embedded air conditioner, and aims to solve the problem that the air output of the air conditioner is influenced due to the fact that the horizontal included angle between the air deflector and the horizontal plane is limited due to the limitation of the air outlet angle.

In some embodiments, the air deflection panel comprises:

a wind deflector body;

the air outlet side extension plate is arranged at the edge of the air outlet side of the air deflector main body; the air outlet side extension plate and the air deflector main body form a first set included angle and incline towards the air outlet side of the air deflector main body;

the edge of the air outlet side extension plate is provided with a noise reduction groove.

In some embodiments, the built-in air conditioner includes: the air deflector.

The air deflector and the embedded air conditioner provided by the embodiment of the disclosure can realize the following technical effects:

in the air deflector of the embodiment of the disclosure, the air-out side extension plate is arranged on the air-out side edge of the air deflector main body in a manner of inclining towards the air-out side of the air deflector main body, so that the air-out side extension plate and the air deflector main body form a first set included angle α 1. Therefore, when the air outlet angle is controlled to be β, the horizontal included angle γ between the air deflector main body and the horizontal plane is α 1+ β, and the horizontal included angle γ is the opening angle γ of the air deflector main body. Therefore, under the condition that the air outlet angle gamma is not changed, the opening angle of the air deflector main body is increased, and the integral air outlet quantity is improved. The edge part of the air outlet side extension plate is provided with the noise reduction groove to separate high-speed airflow at the air outlet side and diffuse the airflow to the upper side and the lower side, so that the high-speed slender airflow is changed into low-custom wide and thick airflow, the heat exchange area of the airflow is increased, and the high-speed aerodynamic noise is reduced.

Referring to fig. 1 to 14, an air deflector according to an embodiment of the present disclosure includes an air deflector body 110 and an air outlet side extension plate 120. As shown in fig. 2 and 3, the air-out side extension plate 120 is disposed at the air-out side edge of the air deflector body 110; the air-out side extension plate 120 forms a first set included angle α 1 with the air deflector main body 110, and inclines towards the air-out surface 101 of the air deflector main body 110. The edge of the air-out side extension plate 120 is provided with a noise reduction groove 122.

In the air deflector of the embodiment of the disclosure, the air-out side extension plate 120 is disposed on the air-out side edge of the air deflector body 110 in a manner of inclining towards the air-out surface 101 of the air deflector body 110, so that the air-out side extension plate 120 and the air deflector body 110 form a first set included angle α 1. That is, the outlet side of the air deflector is bent toward the outlet side to form a broken line type air deflector. As shown in fig. 4 and 5, when the outlet air angle is controlled to be β, a horizontal included angle γ between the air deflector body 110 and the horizontal plane is α 1+ β, and the horizontal included angle γ is the opening angle γ of the air deflector body 110. Therefore, under the condition that the air outlet angle gamma is not changed, the opening angle of the air deflector main body 110 is increased, and the whole air outlet quantity is improved. For example, in the cooling state, the opening angle of the air deflector body 110 can be increased while ensuring a low air outlet angle in the cooling state and non-direct blowing of cold air, so as to increase the overall air outlet amount at the low air outlet angle and ensure sufficient cooling capacity. For example, in the heating state, in order to ensure that the outlet air angle β reaches the air flow angle during heating, the opening angle γ of the air deflector body 110 also needs to satisfy γ ═ α 1+ β, so that the opening width of the air deflector is larger, and the air output of the insertion machine is further increased.

In the embodiment of the present disclosure, the noise reduction groove 122 is formed by forming a notch on the edge of the air outlet side extension plate 120. In the research process, CFD simulation analysis shows that the maximum speed of the airflow at the air outlet side extension plate 120 is an important factor for forming aerodynamic noise, so that a noise reduction groove is designed at the edge part of the air outlet side extension plate 120 to separate the high-speed airflow at the air outlet side and diffuse the airflow to the upper side and the lower side, so that the high-speed elongated airflow is changed into low-quality wide-thick airflow, the heat exchange area of the airflow is increased, and the high-speed aerodynamic noise is reduced.

In the embodiment of the present disclosure, the specific value of the first set included angle α 1 between the air-out side extension plate 120 and the air deflector main body 110 is not limited, and may be any value between 0 ° and 90 °.

Researches find that in a refrigerating state, the air outlet of the air conditioner needs to prevent direct blowing of people, the included angle between the air flow direction of the air outlet and the horizontal plane (namely the air outlet angle beta) needs to be controlled not to be too large, and the air outlet angle beta is ensured to be 5-20 degrees. Then, the horizontal included angle undersize of current straight aviation baffle, the aperture ratio undersize of wind channel directly influences the air output of air conditioner, and along with the horizontal included angle increase of straight aviation baffle, when reaching 35 always, the air output of air conditioner increases gradually, reaches normal operation requirement. And when the horizontal included angle of the straight air guide plate is 10-35 degrees, the air flow is always blown against the ceiling, so that the ceiling is easily blown dirty, and the indoor appearance is influenced. When the horizontal included angle of the straight air deflector is 40-55 degrees, the air outlet quantity of the air conditioner is stable, but the air outlet quantity cannot reach the specified air flow angle.

In some embodiments, the first predetermined included angle α 1 between the air-outlet-side extension plate 120 and the air deflector body 110 is 20 ° to 50 °. That is, the first set angle α 1 may be 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, or 50 °, or any other angle within a range of 20 ° to 40 °. In the cooling state, as shown in fig. 4, when the outlet air angle β is controlled to be 10 °, the opening angle γ of the air guide plate body 110 is 30 ° to 60 °. Meanwhile, as shown in fig. 5, in the heating state, when the outlet air angle β is controlled to be 50 °, the opening angle γ of the air deflector body 110 is 70 ° to 100 °.

In the disclosed embodiment, in practical operation, the opening angle γ is controlled to be not more than 90 °. The wind flow is ensured to be mainly discharged from the wind outlet surface 101 side of the wind deflector 100.

Of course, according to the specific value of the controlled air outlet angle β, a suitable first set included angle α 1 can be selected within the range of 20 ° to 50 °. For example, the wind outlet angle β is 35 °, and the first set angle α 1 is 20 °. For another example, when the outlet air angle β is 20 °, the first set included angle α 1 is 20 ° to 40 °.

Optionally, the first set included angle α 1 between the air-out side extension plate 120 and the air deflector body 110 is 30 °. In the cooling state, when the outlet air angle β is controlled to be 10 °, the opening angle γ of the air deflector body 110 is 40 °. The opening angle of the air deflector main body is increased, the opening rate of the air duct is increased, the integral air output of the embedded air conditioner in a refrigerating state is increased, and the purpose of refrigerating without directly blowing people is achieved while enough refrigerating capacity is ensured. Meanwhile, in the heating state, when the outlet air angle β is controlled to be 50 °, the opening angle γ of the air deflector body 110 is 80 °.

In some embodiments, the air-out side extension plate 120 is rotatably disposed on the air-out side edge of the air deflector body 110, so that the first set included angle α 1 is adjustable. The first set included angle α 1 can be adjusted by the set outlet air angle β and the opening angle γ of the air deflector body 110, so as to satisfy γ ═ α 1+ β. The flexibility is increased.

Optionally, the air-out side extension plate 120 is connected to the air-out side edge of the air deflector body 110 by a rotary buckle structure. For example, the rotary buckle structure comprises a rotary shaft and a rotary groove, wherein a clamping protrusion is arranged on the rotary shaft, and a plurality of clamping grooves are arranged in the rotary groove; the rotation axis inlays and locates in the rotation recess, just the card is protruding can with one of them draw-in groove adaptation, with the rotation axis locking, nonrotatable. When external force is applied to rotate the rotating shaft, the clamping protrusions are driven to rotate together to be matched with the other clamping grooves and locked. Through the interval that sets up the draw-in groove to and draw-in groove and the protruding cooperation size of card etc. can set for the angle between two adjacent draw-in grooves, thereby can adjust first settlement contained angle alpha 1 through the rotation. The external force may be applied manually or by a mechanical external force such as a motor, but is not limited thereto. Of course, the rotary buckle structure is not limited to the specific structure form, and any structure with the same or similar function can be applied.

Optionally, the air-out side extension plate 120 is connected to the air-out side edge of the air deflector body 110 through a damping rotation shaft. The first set included angle alpha 1 can be flexibly adjusted.

In some embodiments, the width d1 of the outlet-side extension plate 120 in the air outlet direction is 10mm to 20 mm. Optionally, the width d1 of the air-outlet side extension plate 120 is 15 mm. When the guiding effect is played, the wind speed is not influenced, and the air outlet strength is ensured.

In some embodiments, the noise reduction grooves 122 are multiple, and the noise reduction grooves 122 are arranged in parallel at the edge of the air-out side extension plate 120 to form a comb-shaped edge.

Optionally, the notches of the noise reduction slots 122 are flared. Further increase the heat exchange area of the air flow and reduce the high-speed aerodynamic noise.

In a refrigerating state, cold air is arranged on the side of the air outlet surface 101 of the air deflector 100, hot air is arranged on the side of the leeward surface 102, and the air deflector is a junction of the cold air and the hot air, so that the air deflector cannot insulate heat and condensation is easily formed. Moreover, when the extension plate 120 on the air outlet side is added, the amount of cold air discharged from the air outlet surface 101 of the air guide plate 100 is increased, and condensation is more likely to form on the air guide plate 100. Therefore, in some embodiments, as shown in fig. 2 and 3, the air deflection 100 further includes an inlet-side extension plate 130 disposed at the inlet-side edge of the air deflection main body 110; the wind inlet side extension plate 130 forms a second set included angle α 2 with the air deflector body 110, and is inclined toward the wind outlet surface 101 of the air deflector body 110. The arrangement of the wind inlet side extension plate 130 increases the effective height H between the highest point of the wind deflector and the lowest point of the arc wind channel on the leeward side, so that the wind flow on the leeward side 102 side of the wind deflector 100 is enhanced, the hot air on the leeward side 102 side of the wind deflector is favorably blown away in a refrigeration state, the temperature difference of the air on the upper side and the lower side of the wind deflector is reduced, and the condensation phenomenon of the wind deflector is favorably eliminated. Moreover, the wind flow on both sides (the wind outlet surface 101 side and the leeward surface 102 side) of the wind deflector 100 acts simultaneously to enhance the stability of the wind flow.

Aiming at the problem that in a heating state, when an opening angle of an existing straight air guide plate reaches a heating air flow angle, short return air is easily generated at air outlet on the leeward side of the straight air guide plate and directly enters an air inlet, hot air enters an air conditioner, heat exchange efficiency of a heat exchanger is affected, and the air conditioner is heated to affect normal use of the air conditioner. After the air inlet side extension plate 130 is added on the air inlet side of the air deflector main body 110, the air quantity and the intensity of the air flow on the leeward side 102 side of the air deflector 100 are enhanced, so that the hot air flowing out from the leeward side 102 side is not easy to absorb by the air inlet of the air conditioner, the short return air phenomenon is avoided, and the heat exchange efficiency and the normal use of the heat exchanger of the air conditioner are ensured.

In the present embodiment, as shown in fig. 4 and 5, a guide structure 230 is further provided on the inner wall of the air duct 201 on the side of the air outlet surface 101 of the air deflector 100 of the built-in air conditioner 200, and the guide structure 230 has a guide surface inclined toward the leeward surface 102 of the air deflector 100. The air guiding structure 230 is disposed above the highest point of the air guiding plate 100. The leading portion of the airflow flows toward the leeward surface 102 of the wind guide plate 100, and the airflow on the leeward surface side is enhanced by the wind-entering-side extension plate 130. Alternatively, the guide structure 230 is a triangular guide block with a right-angled triangle cross section, and a right-angled side and the inner wall of the air duct 201 are used as a guide surface.

In the embodiment of the present disclosure, the specific value of the second set included angle α 2 between the wind-inlet-side extension plate 130 and the wind deflector main body 110 is not limited, and may be any value between 0 ° and 90 °.

In some embodiments, the second predetermined included angle α 2 between the wind-inlet-side extension plate 130 and the wind deflector body 110 is 20 ° to 50 °. That is, the second set angle α 2 may be 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, or 50 °, or any other angle within a range of 20 ° to 40 °.

Optionally, the second set angle α 2 between the wind-inlet-side extension plate 130 and the wind deflector body 110 is 30 °.

In some embodiments, the wind-inlet-side extension plate 130 is rotatably disposed on the wind inlet-side edge of the wind deflector body 110, so that the second set included angle α 2 is adjustable. The flexibility is increased.

Optionally, the wind inlet side extension plate 130 is connected to the wind inlet side edge of the wind deflector body 110 by a rotary buckle structure. The aforementioned rotary fastening structure for connecting the air-out side extension plate 120 and the air-out side edge of the air deflector main body 110 can be adopted, and is not described herein again. Of course, the rotary buckle structure is not limited to the specific structure form, and any structure with the same or similar function can be applied.

Optionally, the wind inlet side extension plate 130 is connected to the wind inlet side edge of the wind deflector main body 110 through a damping rotation shaft. The second set included angle alpha 2 is flexibly adjusted.

In some embodiments, the width d2 of the wind inlet-side extension plate 130 is 10mm to 20mm in the wind outlet direction. Optionally, the width d2 of the wind-inlet side extension plate 130 is 15 mm. When the guiding effect is played, the wind speed is not influenced, and the air outlet strength is ensured.

In some embodiments, as shown in fig. 6 to 8, the air deflector body 110 is provided with micro holes (defined as body micro holes 111); and/or, the outlet side extension plate 120 is provided with micropores (defined as outlet side micropores 121).

Optionally, as shown in fig. 6 (the noise reduction groove 122 is not shown), the air deflector body 110 is provided with micro holes (defined as body micro holes 111). The main body micro holes 111 are distributed on the air deflector main body 110. In the working state of the embedded air conditioner, as shown in fig. 14, when the air deflector 100 is in the closed state, the micro holes can be used as air outlet holes, and air is discharged through the micro holes, so that the air speed can be reduced, and the purpose of cold flow radiation/heat flow radiation is achieved. When the air deflector is in an open state, the air flow at the two sides of the air deflector can carry out certain heat exchange, the condensation of the air deflector is reduced, the overlarge local air speed can be eliminated, and the noise of the air deflector is reduced. Alternatively, the shape of the main body micro-hole 111 is not limited, and may be a circular hole, an elliptical hole, a diamond hole, a triangular hole, a square hole, or other polygonal holes, etc. Optionally, the size of the micro-hole (the main body micro-hole 111) formed on the air deflector main body 110 is 1mm to 5 mm. Optionally, the size of the micropores is from 2mm to 3 mm. Alternatively, the size of the micropores may be reduced from the air outlet surface 101 side to the leeward surface 102 side of the air deflector body 110. When the air deflector is in a closed state, the micropores in the form can buffer the wind speed of the wind flow, further reduce the wind speed, make the blown wind flow softer and achieve the effect of no wind sense. When the air deflector is controlled to be closed, the size of the micropores on the outer side surface (namely, the leeward surface 102 of the air deflector main body 110 when the air deflector is opened) can be controlled to be 1-5 mm. The pore size on the medial side is not limited. Here, the size refers to the size of the micro-hole on the leeward side of the air deflection body 110 when the air deflection is opened. And, size refers to the maximum size of the correspondingly shaped microwell; for example, the diameter of a circular hole, the major axis of an elliptical hole, the diagonal of a rhomboid hole, the side length of a triangular hole, the length of a square hole, etc.

Optionally, as shown in fig. 7 (noise reduction grooves 122 are not shown), the outlet-side extension plate 120 is provided with micro-holes (defined as outlet-side micro-holes 121). The outlet-side micro-holes 121 are distributed on the outlet-side extension plate 120. The wind guide resistance can be reduced. For example, in a heating state, the opening angle of the air deflector body 110 is large, and the micro-holes of the air-outlet-side extension plate 120 reduce the flow resistance of hot air.

Alternatively, the shape of the outlet-side micro-holes 121 is not limited, and may be a circular hole, an elliptical hole, a diamond hole, a triangular hole, a square hole, or other polygonal holes.

Optionally, the size of the micro-holes formed on the air-out side extension plate 120 is 1mm to 4 mm. Optionally, the size of the micropores is from 2mm to 3 mm. Here, the size refers to a size of the micro-hole on the leeward side of the air deflection body 110 when the air deflection is opened. And, size refers to the maximum size of the correspondingly shaped microwell; for example, the diameter of a circular hole, the major axis of an elliptical hole, the diagonal of a rhomboid hole, the side length of a triangular hole, the length of a square hole, etc.

Optionally, the size of the air-out side micro-holes 121 is equal to or smaller than the size of the main body micro-holes 111.

Alternatively, as shown in fig. 8, the air deflector body 110 is provided with micro-holes (defined as body micro-holes 111), and the air-outlet-side extension plate 120 is provided with micro-holes (defined as air-outlet-side micro-holes 121). The structural features of the main body micro-hole 111 and the air-outlet side micro-hole 121 can be referred to the above related contents. And will not be described in detail herein.

Referring to fig. 1 to 9, an embodiment of the present disclosure provides an embedded air conditioner including the air deflector 100.

The embedded air conditioner of the embodiment of the disclosure increases the opening angle of the air deflector body 110 under the condition that the air outlet angle of the air deflector 100 is not changed, and improves the whole air outlet quantity. In the embodiment of the present disclosure, the noise reduction groove 122 is formed by forming a notch on the edge of the air outlet side extension plate 120. The edge part of the air outlet side extension plate 120 is provided with a noise reduction groove to separate high-speed air flow at the air outlet side, and the air flow is diffused to the upper side and the lower side, so that the high-speed slender air flow is changed into low-quality wide and thick air flow, the heat exchange area of the air flow is increased, and the high-speed aerodynamic noise is reduced.

Next, an air deflector is assembled on an embedded air conditioner, wherein the embedded air conditioner is embedded in 5 octahedrons and is installed in the center of a room with the size of 8m multiplied by 8m, and the moving direction of airflow of the embedded air conditioner after air channel optimization is analyzed by CFD simulation. The air guiding plate shown in fig. 2 is adopted, and includes an air guiding plate main body 110, an air outlet side extension plate 120 and an air inlet side extension plate 110. The first set included angle α 1 between the air-out side extension plate 120 and the air deflector main body 110 is 30 °, and the width of the air-out side extension plate 120 is 15 mm. The second set included angle α 2 between the wind-inlet-side extension plate 130 and the air deflector body 110 is 30 °, and the width of the wind-inlet-side extension plate 130 is 15 mm.

CFD simulation analysis was performed for air flow movements with wind outlet angles of 10 ° (as shown in fig. 10 and 11), 45 ° (as shown in fig. 12 and 13), and 55 ° (as shown in fig. 14 and 15), respectively. Meanwhile, the existing straight air guide plate is used for comparison, and air quantity detection and analysis are carried out, as shown in the following table 1.
