The utility model provides an anti-condensation structure 100, which is used for being installed at the lower edge of an air outlet 411 of an air-conditioning indoor unit 40, wherein the air-conditioning indoor unit 40 can be an indoor unit of a wall-mounted air conditioner, and can also be an indoor unit of a cabinet air conditioner or other types of air conditioners.
In the embodiment of the present invention, as shown in the drawing, the condensation preventing structure 100 is configured to be installed at a lower edge of an air outlet 411 of an air conditioning indoor unit 40, the condensation preventing structure 100 includes a first flow guiding part 10 and a second flow guiding part 20, the first flow guiding part 10 has a first flow guiding surface 11, and the first flow guiding part 10 is configured to be connected to the lower edge of the air outlet 411 and extend downward. The second guide portion 20 has a second guide surface 21 connected to the lower end of the first guide surface 11, and a junction of the second guide surface 21 and the first guide surface 11 forms a diversion corner 30.
The anti-condensation structure 100 may be fastened to the casing 41 of the indoor unit 40, fixed to the casing 41 of the indoor unit 40 by a locking member such as a screw, or bonded to the casing 41 of the indoor unit 40. The anti-condensation structure 100 may be formed in a plate shape, that is, the first air guide part 10 and the second air guide part 20 are both formed in a plate shape, and when the anti-condensation structure 100 is mounted on the casing 41 of the indoor air conditioner 40, the inner surface of the anti-condensation structure 100 may be spaced from the surface of the casing 41, that is, the anti-condensation structure 100 and the casing 41 of the indoor air conditioner 40 are enclosed. The inner surface of the condensation preventing structure 100 may be formed to conform to the shape of the surface of the casing 41 of the air conditioning indoor unit 40 so that the inner surface of the condensation preventing structure 100 is attached to the surface of the casing 41 of the air conditioning indoor unit 40 when the condensation preventing structure 100 is attached to the casing 41 of the air conditioning indoor unit 40.
In this embodiment, the air outlet duct of the indoor air conditioner 40 has a duct lower wall surface 412, and when the anti-condensation structure 100 is mounted on the casing 41 of the indoor air conditioner 40, that is, the anti-condensation structure 100 is mounted on the lower edge of the duct lower wall surface 412, the anti-condensation structure 100 extends along the length direction of the air outlet 411 of the indoor air conditioner 40. The first guiding surface 11 extends downward from the lower edge of the air outlet 411, that is, the first guiding surface 11 forms an included angle with the outward extending direction of the air duct lower wall surface 412 (when the air duct lower wall surface 412 is an arc surface, that is, the first guiding surface 11 forms an included angle with the direction of the tangent 413 at the lower edge of the air duct lower wall surface 412). The second guide surface 21 is connected to the lower end of the first guide surface 11, and extends from the lower end of the first guide surface 11 toward the rear side of the indoor air conditioner 40. The first flow guiding surface 11 and the second flow guiding surface 21 are the outer surfaces of the anti-condensation structure 100, and the diversion corner 30 is a convex angle structure.
When the air conditioner is in a cooling mode, the cold air flow is separated at the air outlet 411 through comprehensive theoretical calculation and simulation, and about 70% of the boundary layer air flow is blown out along the extending direction or the tangential line 413 direction of the air duct lower wall surface 412 at the lower edge of the air outlet 411 so as to be far away from the surface (the first flow guide surface 11) of the condensation preventing structure 100 and avoid mixing with the hot air near the first flow guide surface 11. The remaining cool air flows downward along the first guiding surface 11, and when the portion of the cool air flows to the diversion corner 30, because the corner between the first guiding surface 11 and the second guiding surface 21 (i.e. the turning angle when the air flow changes from the flowing direction of the first guiding surface 11 to the flowing direction of the second guiding surface 21) is relatively large, the portion of the cool air flows almost completely leaves the surface of the anti-condensation structure 100 under the action of the diversion corner 30, so that the cool air flow can be prevented from continuously flowing along the second guiding surface 21.
When the cool air flow is blown out from the air outlet 411, a return air flow, which is a room temperature air flow, is formed at the lower side of the indoor air conditioning unit 40. According to the simulation result, about 80% of the backflow airflow flows along the second flow guiding surface 21 toward the diversion corner 30, and when the backflow airflow flows along the second flow guiding surface 21 to the diversion corner 30, because the angle between the second flow guiding surface 21 and the first flow guiding surface 11 is large, the backflow airflow almost completely leaves the surface of the anti-condensation structure 100 under the action of the diversion corner 30, and the cold airflow can be prevented from continuously flowing to the first flow guiding surface 11. Therefore, the mixing amount of the cold air flow and the backflow air flow near the surface (the first guide surface 11) of the condensation prevention structure 100 can be reduced, so that the surface condensation of the condensation prevention structure 100 can be reduced, and the condensation risk of the air outlet 411 is reduced.
The condensation-preventing structure 100 of the present invention comprises a first flow guiding part 10 and a second flow guiding part 20, wherein the first flow guiding part 10 has a first flow guiding surface 11, the second flow guiding part 20 has a second flow guiding surface 21, and the second flow guiding surface 21 is connected to the lower end of the first flow guiding surface 11 by extending the lower edge of the air outlet 411 of the first flow guiding surface 11 downward, so that a diversion corner 30 is formed at the connection between the second flow guiding surface 21 and the first flow guiding surface 11. So when the air conditioner opened the refrigeration mode for along the cold wind air current that first water conservancy diversion face 11 flows and along the backward flow air current that second water conservancy diversion face 21 flows can effectively peel off in reposition of redundant personnel bight 30 department, thereby can reduce the backward flow air current that flows to first water conservancy diversion face 11, and then can reduce the mixed volume of cold wind air current and backward flow air current near preventing condensation structure 100 surfaces, reduce air outlet 411 department condensation risk. The anti-condensation structure 100 in the technical scheme of the utility model can achieve a better anti-condensation effect even in a high-temperature and high-humidity environment with the temperature of 30 ℃ and the humidity of 85%.
In addition, when the risk of condensation is reduced through the outer surface structure of the condensation-preventing structure 100, there is basically no structural requirement for the inner surface of the condensation-preventing structure 100, so that the inner surface of the condensation-preventing structure 100 can adapt to various machine model designs, a new machine model does not need to be designed according to the condensation-preventing structure 100, and the workload of the new machine model development process can be reduced. And for some old models with condensation aberration, only the local die change of the air outlet 411 is needed, and the cost investment is low.
In an embodiment, the first flow guiding surface 11 includes a first flow guiding section 111 and a second flow guiding section 112 connected to a lower end of the first flow guiding section 111, an upper end of the first flow guiding section 111 is used for being connected to a lower edge of the air outlet 411, a junction of the second flow guiding surface 21 and the second flow guiding section 112 forms a diversion corner 30, and an included angle between the first flow guiding section 111 and the vertical direction is greater than an included angle between the second flow guiding section 112 and the vertical direction. Specifically, the first flow guiding section 111 and the second flow guiding section 112 are both arranged in a straight plane, so that the joint of the first flow guiding section 111 and the second flow guiding section 112 forms a corner structure. According to the simulation analysis, in addition to the backflow airflow flowing along the second flow guiding surface 21 toward the diversion corner 30, another backflow airflow flowing along the second flow guiding section 112 toward the first flow guiding section 111 is provided (for convenience of description, the backflow airflow flowing along the second flow guiding surface 21 toward the diversion corner 30 is defined as a first backflow airflow 51, and the backflow airflow flowing along the second flow guiding section 112 toward the first flow guiding section 111 is defined as a second backflow airflow 52), and the second backflow airflow 52 is more likely to cause condensation on the first flow guiding surface 11 than the first backflow airflow 51.
Since the main air flow separated from the cold air flow at the corner structure between the lower edge of the air outlet 411 and the first flow guiding section 111 forms a large-scale cold area above the condensation preventing structure 100 (above the extension line or tangent line 413 extending along the air outlet direction between the first flow guiding section 111 and the air duct lower wall surface 412), the flow rate of the second backflow air flow 52 is relatively small, and is about 20% of the total backflow air flow rate. And the flow rate of the second return airflow 52 is much smaller than that of the main supply airflow, when the second return airflow 52 flows to the corner structure formed at the joint of the first diversion section 111 and the second diversion section 112, the second return airflow 52 is blown away from the first diversion surface 11 by the main supply airflow, and a small-range swirl zone is formed near the joint of the first diversion section 111 and the second diversion section 112, which further hinders the second return airflow 52 from flowing into the region near the first diversion surface 11, so that the heat exchange amount per unit area in the region near the first diversion surface 11 is reduced to about 3% of the original amount, and further condensation is inhibited. Of course, in other embodiments, at least one of the first flow guiding section 111 and the second flow guiding section 112 is provided with a convex arc surface or a concave arc surface. In addition, the first guide surface 11 may be integrally formed as a convex arc surface.
In one embodiment, the second guide section 112 extends vertically downward from the lower end of the first guide section 111. So set up, can guarantee that the air current is great at the corner between second water conservancy diversion section 112 and second water conservancy diversion face 21, can also make second backward flow air current 52 great at the corner of second water conservancy diversion section 112 and first water conservancy diversion section 111 junction, make second backward flow air current 52 blow away from first water conservancy diversion face 11 by main air supply air current more easily, further reduce the mixed volume of cold wind air current and backward flow air current near first water conservancy diversion face 11, reduce air outlet 411 department condensation risk. Of course, in other embodiments, the second flow guiding section 112 may be disposed obliquely to the vertical direction.
In an embodiment, the air outlet duct of the indoor unit 40 has a duct lower wall 412, and an included angle between the first flow guiding section 111 and an extension line or a tangent 413 extending along the air outlet direction of the duct lower wall 412 is greater than or equal to 15 ° and less than or equal to 25 °. Specifically, when the air duct lower wall surface 412 is a flat surface, an extension line 413 of the air duct lower wall surface 412 extending along the air outlet direction is a virtual straight line extending from the air duct lower wall surface 412 to the air outlet 411, that is, an included angle between the first flow guide section 111 and the extension line 413 of the air duct lower wall surface 412 extending along the air outlet direction is greater than or equal to 15 ° and less than or equal to 25 °. When the air duct lower wall surface 412 is a convex arc surface, a tangent 413 extending along the air outlet direction of the air duct lower wall surface 412 is a virtual straight line extending along the tangent 413 at the lower edge of the air duct lower wall surface 412, that is, an included angle between the first flow guide section 111 and the tangent 413 extending along the air outlet direction of the air duct lower wall surface 412 is greater than or equal to 15 ° and less than or equal to 25 °.
When the angle of the diversion corner 30 is kept unchanged, if the included angle between the first diversion section 111 and the extension line or the tangent line 413 of the lower wall surface 412 of the air duct is too large, the turning angle of the air flow between the first diversion section 111 and the second diversion section 112 is reduced, so that the flow rate of the second backflow air flow 52 blown away from the first diversion surface 11 by the main air flow is reduced, more hot air flows are crossed with the cold air flow near the first diversion surface 11, and the condensation risk of the first diversion surface 11 is increased. When the angles of the first flow guiding section 111 and the second flow guiding section 112 are kept unchanged, if the included angle between the first flow guiding section 111 and the extension line or the tangent line 413 of the lower wall surface 412 of the air duct is too large, the turning angle of the airflow at the diversion corner 30 is reduced, so that the risk that the first return airflow 51 flows to the first flow guiding surface 11 is increased, more hot airflow intersects with the cold airflow near the first flow guiding surface 11, and the risk that the first flow guiding surface 11 is exposed to condensation is increased.
If the included angle between the extension line or the tangent 413 of the first flow guide section 111 and the lower wall surface 412 of the air duct is too small, the corner between the lower edge of the air outlet 411 and the first flow guide section 111 is reduced, the separation effect of the cold air flow at the joint of the lower edge of the air outlet 411 and the first flow guide section 111 is deteriorated, and it is difficult to form a vortex region near the joint of the first flow guide section 111 and the second flow guide section 112, so that the condensation prevention effect of the condensation prevention structure 100 is deteriorated.
When the included angle between the first guide section 111 and the extension line or the tangent 413 extending along the air outlet direction of the air duct lower wall surface 412 is set between 15 degrees and 25 degrees, it can be better ensured that a swirl zone is formed near the connection of the first guide section 111 and the second guide section 112, the second backflow airflow 52 is effectively prevented from flowing into the area near the first guide surface 11, the risk that the first backflow airflow 51 flows to the first guide surface 11 can also be reduced, or the second backflow airflow 52 is more easily blown away from the first guide surface 11 by the main supply airflow, the intersection of the backflow airflow and the cold airflow near the first guide surface 11 is reduced, and the condensation risk of the first guide surface 11 is reduced. The included angle between the first flow guide section 111 and the extension line or tangent 413 extending along the air outlet direction of the air duct lower wall surface 412 may be specifically 15 °, 16 °, 17 °, 18 °, 19 °, 20 °, 21 °, 22 °, 23 °, 24 °, 25 °, or the like. Of course, in other embodiments, the included angle between the first flow guiding section 111 and the extension line or tangent line 413 extending along the air outlet direction of the air duct lower wall surface 412 may also be less than 15 ° or greater than 25 °.
In one embodiment, the ratio of the length of the second flow guiding section 112 to the length of the first flow guiding section 111 is greater than or equal to 0.5 and less than or equal to 1. Specifically, the length of the first flow guiding section 111 is the size between the end of the first flow guiding section 111 connected with the lower edge of the air outlet 411 and the second flow guiding section 112, that is, the size of the long side of the first flow guiding section 111 in the cross section of the anti-condensation structure 100. Similarly, the length of the second flow guide section 112 is the dimension between the end of the second flow guide section 112 connected to the first flow guide section 111 and the second flow guide surface 21, that is, the dimension of the long side of the second flow guide section 112 in the cross section of the anti-condensation structure 100.
After the first guide section 111 and the second guide section 112 are provided, when the second return airflow 52 flows to the corner structure formed at the joint of the first guide section 111 and the second guide section 112, the second return airflow 52 is blown off the first guide surface 11 by the main supply airflow, and a small-range swirl zone is formed near the joint of the first guide section 111 and the second guide section 112. Since the swirl region is mainly located near the joint of the first flow guiding section 111 and the second flow guiding section 112, if the length of the second flow guiding section 112 is set too large, the distance between the swirl region and the lower end of the second flow guiding section 112 is relatively long, so that it is difficult to prevent the second backflow airflow 52 from flowing into the area near the first flow guiding surface 11, and the amount of the second backflow airflow 52 (hot airflow) and the amount of the cold airflow merging in the area near the first flow guiding surface 11 (the second flow guiding section 112) are increased, thereby increasing the risk of condensation on the first flow guiding surface 11. If the length of the second flow guiding section 112 is set to be too small, the second flow guiding section 112 is difficult to play a role of guiding the second backflow airflow 52 to flow along the extending direction of the second flow guiding section 112, which easily causes the second backflow airflow 52 to flow into the region of the first flow guiding section 111 beyond the joint of the second flow guiding section 112 and the first flow guiding section 111, i.e. the second backflow airflow 52 is difficult to form a vortex region at the joint of the second flow guiding section 112 and the first flow guiding section 111, which increases the amount of the second backflow airflow 52 (hot airflow) and the cold airflow merging in the region near the first flow guiding surface 11.
When the ratio of the length of the second flow guide section 112 to the length of the first flow guide section 111 is set to be 0.5 to 1, a vortex region can be better formed near the joint of the first flow guide section 111 and the second flow guide section 112, the second backflow air flow 52 is effectively prevented from flowing into the area near the first flow guide surface 11, the backflow air flow is reduced from intersecting with the cold air flow near the first flow guide surface 11, and the risk of condensation of the first flow guide surface 11 is reduced. The ratio of the length of the second flow guiding section 112 to the length of the first flow guiding section 111 may be specifically 0.5, 0.6, 0.7, 0.8, 0.9, or 1. Of course, in other embodiments, the ratio of the length of the second flow guide section 112 to the length of the first flow guide section 111 may also be less than 0.5 or greater than 1.
In one embodiment, the ratio of the length of the second flow guide surface 21 to the length of the first flow guide section 111 is greater than or equal to 3. Specifically, the length of the second guide surface 21 is the dimension from one end of the second guide surface 21 to the other end of the second guide section 112. The length of the first flow guide section 111 is the size between the end of the first flow guide section 111 connected with the lower edge of the air outlet 411 and the second flow guide section 112, that is, the size of the long side of the first flow guide section 111 in the cross section of the condensation preventing structure 100. When the ratio of the length of the second diversion surface 21 to the length of the first diversion section 111 is greater than or equal to 3, the length of the second diversion surface 21 is longer, so that the first return airflow 51 can better flow towards the diversion corner 30 along the second diversion surface 21, the first return airflow 51 can flow at the corner as far as possible away from the surface of the anti-condensation structure 100, the confluence of the first return airflow 51 and the cold airflow on the surface of the anti-condensation structure 100 is reduced, and the risk of condensation is further reduced. Of course, in other embodiments, the ratio of the length of the second guide surface 21 to the length of the first guide section 111 may be less than 3.
In an embodiment, at least a portion of the second guide surface 21 connected to the second guide section 112 extends obliquely downward in a direction away from the second guide section 112. That is, only the portion where the second guide surface 21 and the second guide section 112 are connected may be inclined downward gradually in the direction away from the second guide section 112, or the entire second guide surface 21 may be inclined downward gradually in the direction away from the second guide section 112. Of course, in other embodiments, the second diversion surface 21 may be a plane substantially parallel to the horizontal plane, or at least a portion of the second diversion surface 21 connected to the second diversion section 112 may gradually extend obliquely upward in a direction away from the second diversion section 112
In one embodiment, the ratio of the height difference between the upper edge of second flow guide surface 21 and the lowest position of second flow guide surface 21 to the length of second flow guide surface 21 is less than or equal to 0.15. Specifically, when the second guide surfaces 21 are flat, the ratio of the height difference between the upper edge and the lower edge of the second guide surfaces 21 to the length of the second guide surfaces 21 is 0.15.
