Description

[0001] This application is a divisional application of the invention patent application filed on May 21, 2019, with application number 201910423884.4 and titled "An air guide device and air conditioner for air conditioning". Technical Field

[0002] This invention relates to the field of air conditioning technology, and more specifically, to an air guide device and an air conditioner for use in air conditioning. Background Technology

[0003] Currently, the air delivery distance adjustment of air conditioning equipment is mainly achieved by changing the speed of its fan. For example, when a wall-mounted air conditioner delivers air over a long distance, it often needs to increase its fan speed, which leads to increased power consumption and noise. Conversely, when the air conditioner delivers air over a short distance, its fan speed is low, resulting in low air velocity and the air blown out by the air conditioner not converging, making it difficult to deliver the air to the designated area. This reduces the comfort of using the air conditioning equipment. Summary of the Invention

[0004] The present invention aims to solve, to a certain extent, at least one aspect of the problems that air conditioning equipment cannot accurately deliver air to the designated area during close-range air supply, and the poor comfort of air conditioning equipment during both long-range and short-range air supply.

[0005] To address the aforementioned problems, the present invention provides an air guiding device for an air conditioner, comprising: a first air guiding mechanism positioned at a first working position at the air outlet of the air conditioner, wherein the upper and lower sides of the first air guiding mechanism form gaps with the air outlet, and the side of the first air guiding mechanism facing the inner side of the air outlet is a windward surface, and the side of the first air guiding mechanism facing the outer side of the air outlet is a leeward surface, wherein the leeward surface of the first air guiding mechanism has a first protrusion protruding outward from the air outlet; and...

[0006] The second air guiding mechanism is disposed at the edge of the air conditioner outlet and is used to guide the air blown out of the air conditioner outlet to flow to the opposite sides of the first protrusion, and to make the airflow that is blocked on the back of the first protrusion blow towards the surface of the first protrusion after being reversed; wherein, the second air guiding mechanism includes a first air guiding part formed on the upper side of the air conditioner outlet, and the second air guiding mechanism also includes a second air guiding part formed on the lower side of the air conditioner outlet, and the portion of the second air guiding part located outside the first air guiding mechanism is convex upward.

[0007] Its advantage lies in the fact that the present invention makes full use of the Coanda effect—the tendency of fluids (water or air) to deviate from their original flow direction and instead flow along the surface of a protruding object. This allows the air from the air conditioner vent to flow from two opposite directions along the convex surface of the first protrusion and converge into a wind with a defined flow direction, that is, a wind along the first set flow direction. This allows the air to be clearly directed to the vicinity of the air conditioner, typically within 2 meters, so that users within this vicinity can feel the airflow from the air conditioner and improve their comfort when using the air conditioner.

[0008] Furthermore, the first air guide mechanism is movably positioned in a second working position on the upper side outside the air conditioner outlet, and the windward surface of the first air guide mechanism is located in the flow path of the air blown out of the air conditioner outlet; wherein, the air blown out of the air conditioner outlet flows along a second predetermined flow direction.

[0009] Furthermore, the cross-sectional shape of the first protrusion is arc-shaped, and the outer surface of the first protrusion is an arc surface.

[0010] Its advantages are that when wind adheres to and flows on the first protrusion with an arc-shaped outer surface, on the one hand, the arc-shaped surface guides the wind flowing out from the two sides of the first protrusion to converge. On the other hand, since the first protrusion is convex, the wind will be obstructed by the outer surface of the first protrusion when it flows towards the top of the protrusion, and the arc-shaped surface can reduce the resistance of the wind in the process of flowing towards the top of the first protrusion, thereby reducing the energy loss in the process of wind convergence.

[0011] Furthermore, the air conditioner outlet is elongated, the first air guide mechanism is elongated and extends along the length of the air conditioner outlet, the opposite sides of the length of the first air guide mechanism form gaps with the air conditioner outlet, and the first protrusion is elongated and extends along the length of the first air guide mechanism.

[0012] Its advantages lie in the fact that, considering the air guiding device of the present invention is a modification of existing air conditioning equipment and specifically installed at the air outlet of the air conditioner, and existing air outlets generally adopt a long strip or rectangular structure; for example, the air outlets of wall-mounted air conditioners and central air conditioners are all horizontally extending long strips or rectangular structures, while the air outlets of vertical air conditioners can be vertically set or multiple long strips arranged parallel to each other along the horizontal direction. Therefore, the structure of the first air guiding mechanism and the arrangement of the relative air outlet can be widely used in various existing types of air conditioners; and the structure of the first protrusion and the arrangement of the relative first air guiding mechanism can ensure that the converging airflow forms a planar airflow along the first set flow direction, thereby providing a more comfortable air supply experience for users in the vicinity of the air conditioner.

[0013] Furthermore, the windward surface of the first air guide mechanism is formed with a second protrusion that protrudes towards the inside of the air conditioning outlet.

[0014] Furthermore, the upper end of the first protrusion is adjacent to the upper end of the second protrusion, and the lower end of the first protrusion is adjacent to the lower end of the second protrusion.

[0015] Furthermore, the cross-section of the first air guide mechanism is spindle-shaped.

[0016] Furthermore, the first air guide mechanism also has a second protrusion. In the second working position, the second protrusion protrudes downward and its protrusion direction intersects with the second set flow direction.

[0017] Its advantage lies in the fact that the Coanda effect is utilized again in this invention, so that the wind is blown in a higher direction after passing through the second protrusion, thereby blowing the wind further. In this way, when the air conditioner delivers air over a long distance, if the air delivery distance is the same, the second protrusion of the first air guiding mechanism in this invention can reduce the working load of the air conditioner fan, thereby reducing its energy consumption and the noise generated, thus improving the user's comfort experience under the condition of air conditioner delivering air over a long distance.

[0018] Furthermore, the second protrusion is elongated and extends along the length of the first air guide mechanism.

[0019] Its advantages are as follows: Firstly, considering that the air guiding device of the present invention is a modification of existing air conditioning equipment and specifically installed at the air outlet of the air conditioner, and that existing air conditioning outlets generally adopt a long strip or rectangular structure; for example, the air outlets of wall-mounted air conditioners and central air conditioners are all horizontally extending long strips or rectangular structures, and the air outlets of vertical air conditioners can be vertically set or multiple long strips arranged parallel to each other along the horizontal direction. Therefore, the structure of the first air guiding mechanism and the arrangement of the relative air outlet can be widely used in various types of existing air conditioners; and the structure of the first protrusion and the arrangement of the relative first air guiding mechanism can ensure that the converging airflow forms a planar airflow along the first set flow direction, thereby providing a more comfortable air supply experience for users in the vicinity of the air conditioner. On the other hand, by utilizing the elongated shape of the second protrusion and extending along the length of the first air guide mechanism, the contact area between the second protrusion and the wind is expanded, ensuring that the wind along the second set flow direction is adhered to as much as possible. This expands the Coanda effect, allowing the wind to remain flowing in a direction higher than the second set flow direction, i.e., the third set flow direction, for as long as possible. This ensures and expands the effective range of long-distance air delivery of the air conditioner, and further achieves the effect of reducing the energy consumption and noise of the air conditioner fan under the same long-distance air delivery conditions, thereby further improving the comfort of air conditioner use. The elongated structural feature also reduces the volume and corresponding space occupied by the first guide part and the second protrusion.

[0020] Furthermore, the cross-sectional shape of the second protrusion is arc-shaped, and the outer surface of the second protrusion is arc-shaped.

[0021] Its advantage is that when the wind adheres to the second protrusion with an arc-shaped outer surface and flows, the wind will be obstructed by the outer surface of the second protrusion when it flows towards the top of the second protrusion. The arc-shaped surface can reduce the resistance of the wind when it flows towards the top of the second protrusion, thereby reducing the energy loss during the wind convergence process.

[0022] Furthermore, the first air guide portion forms a first recessed portion that is recessed towards the upper side of the air conditioning outlet, and the upper side of the first air guide mechanism corresponds to the first recessed portion.

[0023] Alternatively, the first air guide portion may form a third protrusion that protrudes downward toward the air conditioner outlet.

[0024] Furthermore, the second air guide portion forms a second recessed portion that is recessed towards the lower side of the air conditioning outlet;

[0025] Alternatively, the second air guide portion forms a fourth protrusion that protrudes upward toward the air conditioner outlet, and the fourth protrusion is located outside the first air guide mechanism.

[0026] Its advantage lies in the fact that, since the first air guide mechanism is located at the air outlet of the air conditioner and obstructs the flow of air, most of the air blown out of the air outlet is blocked by the back of the first protrusion. However, by utilizing the position and structural characteristics of the second air guide mechanism, the airflow that is blocked by the back of the first protrusion can be smoothly reversed and blown onto the surface of the first protrusion, thereby ensuring the smooth operation of the "Coanda effect" on the surface of the first protrusion and the smooth convergence of the airflow with the first set direction.

[0027] Furthermore, the air guide device also includes a connecting arm, one end of which is connected to the first air guide mechanism and the other end of which is connected to the air conditioner, so that the first air guide mechanism can be moved to the first working position or the second working position by rotating the connecting arm.

[0028] Its advantages are that, on the one hand, the connecting arm enables the first air guide mechanism to move relative to the air conditioner outlet, and more importantly, it facilitates the automatic rotation or swing of the connecting arm by forming a mechanical transmission with the motor inside the air conditioner, thereby enabling the first air guide mechanism to move automatically back and forth between the air conditioner outlet and outside the air conditioner outlet, making the air conditioner more convenient to use.

[0029] On the other hand, the present invention also provides an air conditioner, the air conditioner including the air guide device for air conditioning.

[0030] Since the air conditioner is equipped with the air guide device for air conditioning, the technical advantages of the air conditioner are the same as those of the air guide device for air conditioning, so it will not be elaborated on here. Attached Figure Description

Detailed Implementation

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] In the description of this invention, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0039] See Figures 1 to 3 This embodiment provides an air guiding device for an air conditioner, including: a first air guiding mechanism 100, the first air guiding mechanism 100 being placed at a first working position at the air conditioner outlet 300, movably placed at the air conditioner outlet 300, the opposite sides of the first air guiding mechanism 100 forming gaps with the air conditioner outlet 300, and the first air guiding mechanism 100 having a first protrusion 101 protruding outward from the air conditioner outlet 300, i.e., arrow a.

[0040] The working process is as follows: when the air conditioner delivers air at close range, its fan speed is low and the air speed blown out of the air conditioner outlet 300 is low. When the air flows out from the opposite sides of the first air guiding mechanism 100, according to the Coanda effect, the air will flow from the opposite sides of the first air guiding mechanism 100 along the surface of the first protrusion 101. Since the opposite sides of the first air guiding mechanism 100 flow from two different directions, the air will converge and gather at the top of the protrusion of the first protrusion 101 to form air flowing out of the air conditioner outlet 300 in the first set flow direction 301. The first set flow direction 301 is usually the protrusion direction of the first protrusion 101.

[0041] Its advantage lies in the fact that this embodiment makes full use of the Coanda effect—the tendency of fluids (water or air) to deviate from their original flow direction and instead flow along the surface of a protruding object. This allows the air from the air conditioner outlet 300 to flow from two opposite directions along the convex surface of the first protrusion 101 and converge into a wind with a defined flow direction, that is, wind along the first set flow direction 301. This allows the air to be clearly directed to the vicinity of the air conditioner, typically within 2 meters of the air conditioner, so that users within the vicinity of the air conditioner can feel the airflow and improve their comfort when using the air conditioner.

[0042] It should be noted that the airflow speed from the air conditioner is usually 1 m / s or less at this time, which is the airflow speed of the first set flow direction 301.

[0043] In another embodiment, the first air guiding mechanism 100 is movably held in a second working position above the air conditioning outlet 300, the second working position being at least partially located in the flow path of the air blown out of the air conditioning outlet 300; wherein the air blown out of the air conditioning outlet 300 flows along a second predetermined flow direction 302. The first air guiding mechanism 100 is formed with a second protrusion 102, the second protrusion 102 being arranged close to the second predetermined flow direction 302, that is, the second protrusion 102 being located above the second predetermined flow direction 302, the second protrusion 102 protruding downward and intersecting the second predetermined flow direction 302, as shown by arrow b. That is, the positional relationship between the second protrusion 102 and the second predetermined flow direction 302 refers to an intersecting form other than collinearity and parallelism, and the intersecting form includes mutually perpendicular intersecting and non-perpendicular intersecting. As a preferred embodiment, the second protrusion 102 protruding downward perpendicular to the second predetermined flow direction 302 is mutually perpendicular intersecting.

[0044] The working process is as follows: the air from the air conditioner outlet 300 flows along the second set flow direction 302, and the second protrusion 102 is positioned close to and above the second set flow direction 302, so that the air comes into contact with the second protrusion 102 under the Coanda effect and flows along the surface of the second protrusion 102. Since the protrusion direction of the second protrusion 102 intersects the second set flow direction 302, the top of the protrusion of the second protrusion 302 is necessarily lower than its edge. This causes the air to flow along the third set flow direction 303, which is higher than the second set flow direction 302, so that the air blows higher and thus blows farther.

[0045] Its advantage lies in the fact that the Coanda effect is utilized again in this embodiment, so that the wind is blown higher after passing through the second protrusion 102, thereby blowing the wind further. In this way, when the air conditioner delivers air over a long distance, if the air delivery distance is the same, the second protrusion 102 of the first air guide mechanism 100 in this embodiment can reduce the working load of the air conditioner fan, thereby reducing its energy consumption and the noise generated, thus improving the user's comfort experience under the condition of air conditioner delivering air over a long distance.

[0046] It should be noted that in this embodiment, when the air conditioner delivers air over a long distance, the air velocity emanating from its air outlet 300 can range from 10m / s to 20m / s, and the aforementioned range of long-distance air delivery by the air conditioner can refer to a range of 10m to 18m.

[0047] Furthermore, the air conditioner outlet 300 is elongated, the first air guide mechanism 100 is elongated and extends along the length of the air conditioner outlet 300, and the opposite sides of the first air guide mechanism 100 along the length of the air conditioner outlet 300 form gaps with the air conditioner outlet 300, the first protrusion 101 is elongated and extends along the length of the first air guide mechanism 100, and the second protrusion 102 is elongated and extends along the length of the first air guide mechanism 100.

[0048] Its advantages are as follows: Firstly, considering that the air guiding device in this embodiment is a modification of existing air conditioning equipment and specifically installed at the air outlet 300, and that existing air outlets 300 generally adopt a long strip or rectangular structure; for example, the air outlets 300 of wall-mounted air conditioners and central air conditioners are all horizontally extending long strips or rectangular structures, while the air outlets 300 of vertical air conditioners can be vertically installed or multiple long strips arranged parallel to each other along the horizontal direction. Therefore, the structure of the first air guiding mechanism 100 and its arrangement relative to the air outlet 300 can be widely used in various existing types of air conditioners; and the structure of the first protrusion 101 and its arrangement relative to the first air guiding mechanism 100 can ensure that the converging airflow forms a planar airflow along the first set flow direction 301, thereby providing a more comfortable air supply experience for users in the vicinity of the air conditioner. On the other hand, by utilizing the elongated shape of the second protrusion 102 and extending along the length of the first air guiding mechanism 100, the contact area between the second protrusion 102 and the wind is expanded, ensuring that the wind along the second set flow direction 302 is adhered to as much as possible, thereby expanding the Coanda effect and keeping the wind flowing along a direction higher than the second set flow direction 302 for as long as possible, that is, along the third set flow direction 303. This ensures and expands the effective range of long-distance air supply of the air conditioner, and further achieves the effect of reducing the energy consumption and noise of the air conditioner fan under the same long-distance air supply conditions, thereby further improving the comfort of air conditioner use. The elongated structural feature reduces the volume and corresponding space occupied by the first protrusion 101 and the second protrusion 102.

[0049] Furthermore, the cross-sectional shape of the second protrusion 102 is arc-shaped, and the outer surface of the second protrusion 102 is arc-shaped.

[0050] It should be noted that the arc mentioned in this embodiment includes, on the one hand, an arc formed by splicing multiple circular arcs together, and on the other hand, an elliptical arc and a smooth curved surface; on the other hand, the arc mentioned in this embodiment can also be equivalent to a circular arc. Therefore, the arc mentioned again in the following text of this embodiment is also applicable and will not be repeated.

[0051] When wind adheres to and flows on the second protrusion 102, which has an arc-shaped outer surface, the wind will be obstructed by the outer surface of the second protrusion 102 when it flows towards the top of the protrusion. The arc-shaped surface can reduce the resistance of the wind when it flows towards the top of the protrusion, thereby reducing the energy loss during the wind convergence process.

[0052] In another embodiment, the air conditioner outlet 300 is elongated, the first air guide mechanism 100 is elongated and extends along the length of the air conditioner outlet 300, and the opposite sides of the first air guide mechanism 100 along the length of the air conditioner outlet 300 form gaps with the air conditioner outlet 300, and the first protrusion 101 is elongated and extends along the length of the first air guide mechanism 100.

[0053] Its advantage lies in the fact that, considering the air guiding device of this embodiment is a modification of existing air conditioning equipment and specifically installed at the air outlet 300, and the existing air outlet 300 generally adopts a long strip or rectangular structure; for example, the air outlet 300 of wall-mounted air conditioners and central air conditioners are both horizontally extending long strips or rectangular structures, and the air outlet 300 of vertical air conditioners can be vertically set or multiple long strips arranged parallel to each other along the horizontal direction. Therefore, the structure of the first air guiding mechanism 100 and its arrangement relative to the air outlet 300 can be widely used in various existing types of air conditioners; and the structure of the first protrusion 101 and its arrangement relative to the first air guiding mechanism 100 can ensure that the converging air flows along the first set flow direction 301 to form a planar airflow, thereby providing a more comfortable air supply experience for users in the vicinity of the air conditioner.

[0054] Furthermore, the cross-sectional shape of the first protrusion 101 is arc-shaped, and the outer surface of the first protrusion 101 is arc-shaped.

[0055] Its advantage lies in the fact that when wind adheres to and flows on the first protrusion 101, which has an arc-shaped outer surface, on the one hand, the arc-shaped surface guides the wind flowing out from the two sides of the first protrusion 101 to converge. On the other hand, since the first protrusion 101 is convex, the wind will be obstructed by the outer surface of the first protrusion 101 when it flows towards the top of the protrusion. The arc-shaped surface can reduce the resistance of the wind when it flows towards the top of the protrusion, thereby reducing the energy loss during the wind convergence process.

[0056] In another embodiment, the air guiding device for the air conditioner further includes a second air guiding mechanism disposed at the air conditioner outlet 300. The second air guiding mechanism is used to guide the air blown out of the air conditioner outlet 300 to flow to the opposite sides of the first protrusion 101.

[0057] Furthermore, the second air guiding mechanism includes a first air guiding part 201 formed on the upper side of the air conditioning outlet 300;

[0058] The first air guide portion 201 forms a first recessed portion that is recessed towards the upper side of the air conditioning outlet 300, or the first air guide portion 201 forms a third protruding portion that is protruding towards the lower side of the air conditioning outlet 300.

[0059] Furthermore, the second air guiding mechanism includes a second air guiding part 202 formed on the lower side of the air conditioning outlet 300;

[0060] The second air guide 202 forms a second recessed portion that is recessed towards the lower side of the air conditioning outlet 300, or the second air guide 201 forms a fourth protruding portion that is protruding towards the upper side of the air conditioning outlet 300.

[0061] In this way, the first air guide 201 and the second air guide 202 can form various combinations, such as: the first air guide 201 forming a first recessed portion and the second air guide 202 forming a second recessed portion; the first air guide 201 forming a third protrusion and the second air guide 202 forming a fourth protrusion; the first air guide 201 forming a third protrusion and the second air guide 202 forming a second recessed portion; the first air guide 201 forming a first recessed portion and the second air guide 202 forming a fourth protrusion.

[0062] Correspondingly, the specific form of the first air guide section 201 and the second air guide section 202 can be determined according to the actual use of the air conditioner.

[0063] Preferably, the first air guide 201 forms a first recess, and the second air guide 202 forms a fourth protrusion, and is used in a wall-mounted air conditioner.

[0064] Its advantage is that, since the first air guide mechanism 100 is located at the air outlet 300 of the air conditioner and obstructs the flow of air, most of the air blown out of the air outlet 300 is blocked by the back of the first protrusion 101. However, by utilizing the position and structural characteristics of the second air guide mechanism 200, the airflow that is blocked by the back of the first protrusion 101 can be smoothly reversed and blown onto the surface of the first protrusion 101, thereby ensuring the smooth operation of the "Coanda effect" on the surface of the first protrusion 101 and the smooth convergence of the airflow in the first set flow direction 301.

[0065] In the above embodiments, the first air guiding mechanism 100 is fixed with a connecting arm 103. One end of the connecting arm 103 is connected to the first air guiding mechanism 100, and the other end of the connecting arm 103 is connected to an air conditioner, so that the first air guiding mechanism 100 can be moved to a first working position or a second working position by rotating the connecting arm 103.

[0066] Its advantages are that, on the one hand, the connecting arm 103 enables the first air guide mechanism 100 to move relative to the air conditioner outlet 300, and more importantly, it facilitates the formation of mechanical transmission between the connecting arm 103 and the motor inside the air conditioner, so as to realize the automatic rotation or swing of the connecting arm 103, thereby realizing the automatic reciprocating movement of the first air guide mechanism 100 between the air conditioner outlet 300 and outside the air conditioner outlet 300, making the use of the air conditioner more convenient.

[0067] Specifically, when the first air guide mechanism 100 is elongated, there can be two connecting arms 103, which are fixed to the two ends of the first air guide mechanism 100 along its length. Then, the two connecting arms 103 are connected to the air conditioner.

[0068] Additionally, it should be noted that in the above embodiments, in order to meet specific production and usage needs, the "strip shape" can be replaced with a "rectangular structure" that is wider than the "strip shape".

[0069] In another embodiment, an air conditioner is also provided, including a wall-mounted air conditioner and a floor-standing air conditioner. After the air conditioner is equipped with the aforementioned air guide device for air conditioning, the technical advantages of the air conditioner are the same as the technical advantages of the aforementioned air guide device for air conditioning, so it will not be described again.

[0070] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
