Detailed Implementation

[0022] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0023] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides an air guide plate assembly 100, including: an air guide plate base 1, a first insulation layer 2, and a second insulation layer 3.

[0024] The first insulation layer 2 is disposed on one side of the air guide plate substrate 1, and the second insulation layer 3 is disposed on the other side of the air guide plate substrate 1. Both the first insulation layer 2 and the second insulation layer 3 are soft insulation layers. The first insulation layer 2 and the second insulation layer 3 may be made of the same or different materials, and the material of the air guide plate substrate 1 is different from the materials of the first insulation layer 2 and the second insulation layer 3.

[0025] If the air guide plate substrate 1 is a rigid substrate (such as a plastic part), then any insulation layer with a lower hardness than the air guide plate substrate 1 is a soft insulation layer. In other words, the hardness of a soft insulation layer is less than the hardness of the air guide plate substrate 1. For example, if the air guide plate substrate 1 is an ABS (Acrylonitrile Butadiene Styrene plastic) plastic part, then any insulation layer with a lower hardness than ABS plastic is a soft insulation layer.

[0026] The air guide plate assembly 100 provided in this application embodiment has insulation layers (i.e., a first insulation layer 2 and a second insulation layer 3) on both sides of the air guide plate substrate 1, which can realize the functions of air guiding and anti-condensation. Compared with setting a single insulation layer on one side of the air guide plate substrate, the double insulation layer has a better insulation effect, thus helping to improve the anti-condensation effect of the air guide plate assembly.

[0027] The materials of the first insulation layer 2 and the second insulation layer 3 can be the same or different, allowing for the selection of materials and processing methods for both insulation layers to meet different usage requirements. The material of the air guide plate substrate 1 is different from that of the first insulation layer 2 and the second insulation layer 3, ensuring that the hardness of the air guide plate substrate 1 is greater than that of the first insulation layer 2 and greater than that of the second insulation layer 3.

[0028] In some exemplary embodiments, the first insulation layer 2 and / or the second insulation layer 3 are sealing elements so that the air guide plate assembly 100 can seal the corresponding air duct or air outlet.

[0029] Since both the first insulation layer 2 and the second insulation layer 3 are soft insulation layers capable of elastic deformation, when the air guide plate assembly 100 closes the corresponding air outlet, the first insulation layer 2 or the second insulation layer 3 can press tightly against the wall of the corresponding air duct or air outlet, allowing the air guide plate assembly 100 to seal the corresponding air duct or air outlet and prevent air leakage between the air duct or air outlet and the air guide plate assembly 100, thereby achieving a sealing function. Therefore, the air guide plate assembly 100 can be used as an air damper (or air valve). Thus, the air guide plate assembly 100 provided in this embodiment of the application combines air guiding, anti-condensation, and sealing functions, which is beneficial for expanding the application scenarios of the air guide plate assembly 100.

[0030] For example, for air conditioners with multiple air outlets, when only some air outlets need to be opened, the air guide plate assembly 100 can be used to seal other air outlets that do not need to be opened, so as to avoid air leakage at these air outlets, which would affect the air volume of the air conditioner or cause condensation problems. This is beneficial to improving the performance of air conditioners with multiple air outlets and the user experience.

[0031] Of course, the air guide plate assembly 100 can also be used as an ordinary air guide plate. If it is not used as an air door or air valve, the soft insulation layer only has the function of heat preservation and does not have the function of sealing.

[0032] In some exemplary embodiments, such as Figure 3 As shown, the air guide plate base 1 includes a rotating shaft portion 11 and an air guide portion 12. The central axis of the rotating shaft portion 11 is the rotation axis of the air guide plate assembly 100. One or both ends of the rotating shaft portion 11 can be connected to a drive mechanism, allowing the air guide plate assembly 100 to rotate under the drive of the drive mechanism. The rotating shaft portion 11 and the air guide portion 12 are arranged and connected along the width direction of the air guide plate base 1. Therefore, the rotating shaft portion 11 is located at one end of the width direction of the air guide plate base 1, rather than in the middle of the air guide plate as in conventional technology. In this way, the air guide plate assembly 100 does not need to be fully embedded in the corresponding air outlet, but is located outside the air outlet, achieving the function of closing and sealing the corresponding air duct or air outlet by completely covering the corresponding air duct port or air outlet. Therefore, the area enclosed by the circumferential edge of the air guide plate assembly 100 is larger than the area of ​​the corresponding air duct port or air outlet, and the first insulation layer 2 or the second insulation layer 3 abuts against the outside of the corresponding air duct port or air outlet, thus achieving the function of sealing the air duct or air outlet.

[0033] The first insulation layer 2 covers at least a portion of one side panel of the air guide 12, and the second insulation layer 3 covers at least a portion of the other side panel of the air guide 12. In other words, the first insulation layer 2 can cover a portion or the entire side panel of the air guide 12. Similarly, the second insulation layer 3 can cover a portion or the entire side panel of the air guide 12. Of course, the first insulation layer 2 and / or the second insulation layer 3 can also extend to the location of the rotating shaft 11, covering a portion of the rotating shaft 11. The rotating shaft 11 can be provided with a filling groove for the first insulation layer 2 / second insulation layer 3 to fill.

[0034] Since the rotating shaft 11 primarily functions as a rotating part, requiring reciprocating rotation, a certain gap needs to be maintained between the rotating shaft 11 and the air conditioner housing 200 to prevent interference during rotation. Therefore, the rotating shaft 11 is not suitable as a sealing part of the air guide plate assembly 100. Furthermore, the air guide section 12 has a large contact area with the airflow. Therefore, the first insulation layer 2 and the second insulation layer 3 must at least cover both sides of the air guide section 12 to facilitate sealing between the air guide section 12 and the corresponding air outlet, thereby reducing air leakage and condensation risks.

[0035] The air guide section 12 can be roughly in the shape of an arc plate. The first insulation layer 2 is located on the side where the concave surface of the air guide section 12 is located (the side where the concave surface is located is called the inner side), and the second insulation layer 3 is located on the side where the convex surface of the air guide section 12 is located (the side where the convex surface is located is called the outer side).

[0036] In some exemplary embodiments, the air guide plate assembly 100 has a stepped portion 4 at the end away from the rotating shaft portion 11 (e.g., Figure 13 , Figure 15 and Figure 17 (The part indicated by the dashed box in the middle). The step portion 4 includes a portion of the air guide portion 12, and the step portion 4 also includes a portion of the first insulation layer 2 and / or a portion of the second insulation layer 3.

[0037] like Figure 13 , Figure 15 and Figure 17 As shown, the stepped portion 4 has a first wall surface 41 and a second wall surface 42 disposed opposite to each other along the thickness direction of the air guide plate base 1. The first wall surface 41 is bent relative to other parts of the air guide plate assembly 100 to form at least one sealing step 14. The second wall surface 42 is a smooth wall surface that smoothly contacts other parts of the air guide plate assembly 100.

[0038] Thus, the end of the air guide plate assembly 100 furthest from the pivot 11 is relatively thin and has a stepped structure, which facilitates sealing between the air guide plate assembly 100 and adjacent air guide plate assemblies 100 or other components through overlapping (e.g., Figures 6 to 11As shown in the figure, avoiding excessive thickness at the overlap can reduce the risk of interference or even jamming at the overlap, and it can also increase the sealing area through the overlap of multiple stepped surfaces, thereby improving the sealing reliability of the overlap.

[0039] Furthermore, the stepped portion 4 has a stepped surface on only one side wall (first wall 41), while the other side wall is a smooth surface. This makes the side wall of the air guide plate assembly 100 relatively simple and complete, which is convenient for the side wall to serve as the appearance surface of the air guide plate assembly 100, thereby improving the aesthetics of the air guide plate assembly 100.

[0040] In some exemplary embodiments, such as Figure 13 , Figure 15 and Figure 17 As shown, the portion of the air guide 12 located in the stepped portion 4 is designated as the air guide tail 121. The air guide tail 121 is constructed as a smooth portion 1211 or at least one bent portion 1212.

[0041] At least a portion of one side wall of the air guide tail 121 is covered by the first insulation layer 2; and / or at least a portion of the other side wall of the air guide tail 121 is covered by the second insulation layer 3.

[0042] In other words, the tail of the air guide 12 can be configured as a smooth section 1211 (e.g. Figure 13 and Figure 17 As shown), no bending portion 1212 is provided. The smooth portion 1211 may have only a portion of its inner wall surface covered by the first insulation layer 2, while the outer wall surface may have a second insulation layer 3 (as shown). Figure 17 As shown), the second insulation layer 3 can also be omitted (e.g. Figure 15 (As shown). Alternatively, the smooth portion 1211 may have only a portion of its outer wall surface covered by the second insulation layer 3, while the inner wall surface may or may not have the first insulation layer 2. This solution can construct at least a portion of the first wall surface 41 through the first insulation layer 2 / second insulation layer 3, and construct at least a portion of the second wall surface 42 through the air guide tail 121. This simplifies the structure of the air guide plate substrate 1 and facilitates the processing and forming of the air guide plate substrate 1.

[0043] Alternatively, the tail of the air guide 12 can be configured as a bent section 1212 similar to a stepped structure, such as... Figure 15 As shown. In this case, the bent portion 1212 may have only a portion of its inner wall surface covered by the first insulation layer 2 (e.g., Figure 15As shown), the outer wall surface may or may not have a second insulation layer 3. Alternatively, the bending portion 1212 may only have at least a portion of the outer wall surface covered by the second insulation layer 3, while the inner wall surface may or may not have a first insulation layer 2. This solution can construct at least a portion of the second wall surface 42 through the first insulation layer 2 / second insulation layer 3, and construct at least a portion of the first wall surface 41 through the air guide tail 121.

[0044] In one embodiment, such as Figure 13 As shown, the air guide tail 121 is constructed as a smooth section 1211. One side wall of the air guide tail 121 is covered by a first insulation layer 2, and a portion of the other side wall of the air guide tail 121 is covered by a second insulation layer 3. The surface of the air guide plate substrate 1 facing away from the first insulation layer 2 has a U-shaped strip groove, and the second insulation layer 3 is embedded in the strip groove, forming a U-shaped strip structure, as shown... Figure 12 As shown. The two ends of the second insulation layer 3 cover parts of the wall surface of the air guide tail 121. The surface of the air guide tail 121 facing away from the wall surface of the first insulation layer 2 and the surface of the second insulation layer 3 located at the step portion 4 (in Figure 13 (Not shown due to the choice of the cutting position) Together they form the second wall surface 42 of the stepped portion 4. The first insulation layer 2 forms the first wall surface 41 of the stepped portion 4.

[0045] In this embodiment, the first wall surface 41 is the inner wall surface of the stepped portion 4, and the second wall surface 42 is the outer wall surface of the stepped portion 4. The first insulation layer 2 can abut against the opening wall of the corresponding air duct port or air outlet to seal the air duct port or air outlet, such as... Figure 7 As shown. The second insulation layer 3 can abut against a portion of the corresponding duct port or air outlet wall to seal the duct port or air outlet portion, such as... Figure 6 As shown. The second insulation layer 3 of this air guide plate assembly can cooperate with the second insulation layer 3 of another air guide plate assembly. The overlapping part of the two is sealed by a sealing step, thereby jointly sealing a complete air duct port or air outlet, such as... Figure 6 As shown.

[0046] In another embodiment, such as Figure 15 As shown, the air guide tail 121 is constructed as two bent sections 1212, each bent section 1212 having two consecutively connected bent surfaces. The three bent surfaces of the air guide tail 121 are covered by a first insulation layer 2, and a portion of the other side wall of the air guide tail 121 is covered by a second insulation layer 3, as shown. Figure 14 As shown. The surface of the air guide plate substrate 1 facing away from the first insulation layer 2 has a U-shaped groove. The second insulation layer 3 is embedded in the groove, forming a U-shaped strip structure, as shown. Figure 14As shown. The two ends of the second insulation layer 3 cover part of the wall surface of the air guide tail 121, as shown. Figure 14 As shown. The bent surface of the air guide tail 121 facing away from the second insulation layer 3 and not covered by the first insulation layer 2, together with the first insulation layer 2, forms the second wall surface 42 of the stepped portion 4. The wall surface of the air guide tail 121 facing away from the first insulation layer 2 and the surface of the second insulation layer 3 located in the stepped portion 4 (in Figure 15 (Not shown due to the choice of the cutting position) together form the first wall surface 41 of the stepped part 4.

[0047] In this embodiment, the first wall surface 41 is the outer wall surface of the stepped portion 4, and the second wall surface 42 is the inner wall surface of the stepped portion 4. The first insulation layer 2 can abut against the opening wall of the corresponding air duct port or air outlet to seal the port or air outlet. The second insulation layer 3 can abut against a portion of the opening wall of the corresponding air duct port or air outlet to seal a portion of the port or air outlet, such as... Figure 6 As shown. The second insulation layer 3 of this air guide plate assembly can cooperate with the second insulation layer 3 of another air guide plate assembly. The overlapping part of the two is sealed by a sealing step, thereby jointly sealing a complete air duct port or air outlet, such as... Figure 6 As shown.

[0048] In yet another embodiment, such as Figure 17 As shown, the air guide tail 121 is constructed as a smooth portion 1211. One side wall of the air guide tail 121 is covered by a first insulation layer 2, and a portion of the other side wall of the air guide tail 121 is covered by a second insulation layer 3, as shown. Figure 17 As shown. The surface of the air guide plate substrate 1 facing away from the first insulation layer 2 has a rectangular groove. The second insulation layer 3 is embedded in the groove, forming a rectangular strip structure extending circumferentially along the air guide plate substrate 1, as shown. Figure 16 As shown. The end of the second insulation layer 3 furthest from the pivot 11 covers a portion of the wall surface of the air guide tail 121, as shown. Figure 16 As shown. The surface of the air guide tail 121 facing away from the first insulation layer 2 and the surface of the second insulation layer 3 located at the step 4 together constitute the second wall surface 42 of the step 4, as shown. Figure 17 As shown. The first insulation layer 2 forms the first wall surface 41 of the stepped portion 4, as... Figure 17 As shown.

[0049] In this embodiment, the first wall surface 41 is the inner wall surface of the stepped portion 4, and the second wall surface 42 is the outer wall surface of the stepped portion 4. The first insulation layer 2 can abut against the opening wall of the corresponding air duct port or air outlet to seal the air duct port or air outlet, such as... Figure 10 As shown. The second insulation layer 3 can abut against the wall of the corresponding duct port or air outlet to seal the duct port or air outlet, such as... Figure 9 As shown.

[0050] In some exemplary embodiments, the coverage area of ​​the first insulation layer 2 is greater than or equal to the coverage area of ​​the second insulation layer 3. The width of the air guide plate base 1 is denoted as W1 (e.g., ...). Figure 1 As shown), the width of the second insulation layer 3 is denoted as W2 (e.g. Figure 2 As shown). Figure 1 As shown, the distance between the first insulation layer 2 and the first end of the air guide plate base 1 in the width direction is denoted as La1, the distance between the first insulation layer 2 and the second end of the air guide plate base 1 in the width direction is denoted as La2, the distance between the first insulation layer 2 and the first end of the air guide plate base 1 in the length direction is denoted as La3, and the distance between the first insulation layer 2 and the second end of the air guide plate base 1 in the length direction is denoted as La4. Figure 2 As shown, the distance between the second insulation layer 3 and the end of the air guide plate base 1 closest to the rotation axis of the air guide plate assembly 100 in the width direction is denoted as Lb1, the distance between the second insulation layer 3 and the first end of the air guide plate base 1 in the length direction is denoted as Lb2, and the distance between the second insulation layer 3 and the second end of the air guide plate base 1 in the length direction is denoted as Lb3.

[0051] The first end of the air guide plate base 1 in the width direction is the end of the air guide plate base 1 that is close to the rotation axis of the air guide plate assembly 100 in the width direction. Figure 3 In the middle, the end of the air guide plate base 1 is the left edge of the rotating shaft part 11.

[0052] Wherein, 0≤La1≤t1, 0≤La2≤t1, 0≤La3≤t2, 0≤La4≤t2; 0≤Lb1≤t3, 0≤Lb2≤t4, 0≤Lb3≤t4; W2≤W1; t1 is the first setting value, t2 is the second setting value, t3 is the third setting value, and t4 is the fourth setting value.

[0053] In some embodiments, 0 < t1 ≤ 150 mm, 0 < t2 ≤ 150 mm, 0 < t3 ≤ 2000 mm, and 0 < t4 ≤ 150 mm.

[0054] Therefore, the first insulation layer 2 covers at least a portion of one side of the air guide plate substrate 1, and the second insulation layer 3 covers at least a portion of the other side of the air guide plate substrate 1.

[0055] In some embodiments, such as Figure 1 and Figure 2As shown, the first insulation layer 2 covers a portion of one side of the air guide plate substrate 1, and the second insulation layer 3 covers a portion of the other side of the air guide plate substrate 1. Wherein, 0 < La1 ≤ t1, 0 ​​< La2 ≤ t1, 0 ​​< La3 ≤ t2, 0 < La4 ≤ t2; 0 < Lb1 ≤ t3, 0 < Lb2 ≤ t4, 0 < Lb3 ≤ t4; W2 < W1.

[0056] In other words, the first insulation layer 2 partially covers one side of the air guide plate substrate 1, and there is a gap between the circumferential edge of the first insulation layer 2 and the circumferential edge of the side of the air guide plate substrate 1. The circumferential edge of the first insulation layer 2 is located inside the circumferential edge of the side of the air guide plate substrate 1. The circumferential edge of the side of the air guide plate substrate 1 can protrude away from the second insulation layer 3 to form a first retaining edge, so that the side of the air guide plate substrate 1 forms a first receiving groove. The first insulation layer 2 can then be embedded in the first receiving groove, which facilitates the processing and forming of the first insulation layer 2 and also helps to improve the connection reliability between the first insulation layer 2 and the air guide plate substrate 1.

[0057] The second insulation layer 3 partially covers the other side of the air guide plate substrate 1, and there is a gap between a portion of the circumferential edge of the second insulation layer 3 and the corresponding portion of the circumferential edge of the side surface of the air guide plate substrate 1. A portion of the circumferential edge of the second insulation layer 3 is located inside the corresponding portion of the circumferential edge of the side surface of the air guide plate substrate 1. The corresponding portion of the circumferential edge of the side surface of the air guide plate substrate 1 can protrude away from the first insulation layer 2 to form a second retaining edge, so that the side of the air guide plate substrate 1 forms a second receiving groove, and the second insulation layer 3 can be embedded in the second receiving groove, which facilitates the processing and forming of the second insulation layer 3 and also helps to improve the connection reliability between the second insulation layer 3 and the air guide plate substrate 1.

[0058] like Figure 2As shown, the second insulation layer 3 can be configured as a U-shaped strip structure, including a first insulation part 31, a second insulation part 32, and a third insulation part 33 connected in sequence. The first insulation part 31 extends along the width direction of the air guide plate base 1, and the distance between it and the first end in the length direction of the air guide plate base 1 is denoted as Lb2. The third insulation part 33 extends along the width direction of the air guide plate base 1, and the distance between it and the second end in the length direction of the air guide plate base 1 is denoted as Lb3. The second insulation part 32 extends along the length direction of the air guide plate base 1, and the distance between it and the end in the width direction of the air guide plate base 1 that is close to the rotation axis of the air guide plate assembly 100 is denoted as Lb1. The width of the second insulation part 32 (the distance between its two ends perpendicular to its extension direction, i.e., the distance between its two ends along the width direction of the air guide plate base 1) can be denoted as the width of the second insulation layer 3. The widths of the first insulation section 31 (the distance between its two ends perpendicular to its extension direction, i.e., the distance between its two ends along the length direction of the air guide plate base 1), the second insulation section 32 (the distance between its two ends perpendicular to its extension direction, i.e., the distance between its two ends along the width direction of the air guide plate base 1), and the third insulation section 33 (the distance between its two ends perpendicular to its extension direction, i.e., the distance between its two ends along the length direction of the air guide plate base 1) may be equal, unequal, or not completely equal.

[0059] The first insulation layer 2 and the second insulation layer 3 partially cover the air guide plate substrate 1, which helps to reduce the amount of insulation material used, thereby reducing the production cost of the air guide plate assembly 100, and the air guide plate substrate 1 has good strength.

[0060] In some other embodiments (not shown in the figures), the first insulation layer 2 covers the entire surface of one side of the air guide plate substrate 1, and the second insulation layer 3 covers the entire surface of the other side of the air guide plate substrate 1. Wherein, La1=0, La2=0, La3=0, La4=0, Lb1=0, Lb2=0, Lb3=0, and W2=W1.

[0061] Thus, the air guide plate assembly 100 has a three-layer structure, and the insulation material covers a large area, which is beneficial to improving the insulation performance of the air guide plate assembly 100.

[0062] In some exemplary embodiments, the air guide plate substrate 1 is a plastic part, which can be processed and molded by injection molding, extrusion, etc., with mature processing technology and low production cost. The first insulation layer 2 is a polyurethane foam component, which has good thermal insulation performance and sealing performance. The second insulation layer 3 is a polyurethane foam component, which also has good thermal insulation performance and sealing performance.

[0063] Of course, the air guide plate substrate 1 is not limited to the above materials and can also be other materials. The first insulation layer 2 and the second insulation layer 3 are not limited to the above materials and can also be EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), etc.

[0064] In some exemplary embodiments, such as Figure 4 and Figure 5 As shown, the air guide plate base 1 has a connecting region 13, and the connecting region 13 has a connecting hole 131 that penetrates the air guide plate base 1 along the thickness direction of the air guide plate base 1. The air guide plate assembly 100 also includes a connecting part (not shown in the figure) located in the connecting hole 131, and the connecting part connects the first insulation layer 2 and the second insulation layer 3. There can be multiple connecting holes 131, and the multiple connecting holes 131 are spaced apart along the length direction of the connecting region 13.

[0065] In this way, the first insulation layer 2 and the second insulation layer 3 can be pulled together through the connecting part, which helps to reduce the risk of the first insulation layer 2 or the second insulation layer 3 falling off, thereby improving the reliability of the air guide plate assembly 100.

[0066] In other embodiments, the air guide plate substrate 1 may not have a connecting region 13. The first insulation layer 2 and the second insulation layer 3 are not connected. The materials of the first insulation layer 2 and the second insulation layer 3 may be the same or different; the manufacturing processes of the first insulation layer 2 and the second insulation layer 3 may be the same or different.

[0067] In some exemplary embodiments, the first insulation layer 2, the second insulation layer 3, and the connecting portion are integrally formed by foaming, such as foamed rubber. This simplifies the manufacturing process of the air guide plate assembly 100, achieving double-sided foaming in a single foaming process, which helps improve the production efficiency of the air guide plate assembly 100. The materials of the first insulation layer 2, the second insulation layer 3, and the connecting portion can be, but are not limited to, polyurethane.

[0068] In some exemplary embodiments, such as Figure 4 and Figure 5 As shown, the distance between the connected region 13 and one end of the air guide plate base 1 closest to the rotation axis of the air guide plate assembly 100 in the width direction is denoted as L1, the distance between the connected region 13 and the first end of the air guide plate base 1 in the length direction is denoted as L2, and the distance between the connected region 13 and the second end of the air guide plate base 1 in the length direction is denoted as L3. Wherein, L1>0, L2>0, L3>0.

[0069] In some implementations, 0 < L1 ≤ 200 mm, 0 < L2 ≤ 100 mm, and 0 < L3 ≤ 100 mm.

[0070] In this way, the connecting hole 131 of the connecting region 13 is located inside the air guide plate base 1 and does not extend to the edge of the air guide plate base 1, causing the edge of the air guide plate base 1 to be penetrated, which is beneficial to improving the structural strength of the air guide plate base 1.

[0071] The connecting area 13 can be set to correspond to the edge area of ​​the air vent, and the second insulation layer 3 can be set to correspond to the connecting area 13.

[0072] like Figures 6 to 8 As shown in the illustration, this application also provides an air conditioner, including a housing 200 and an air guiding mechanism. The housing 200 has an air duct 204 and an air outlet communicating with the air duct 204. The air guiding mechanism includes an air guide plate assembly 100 as described in any of the above embodiments, and the air guide plate assembly 100 is located at the air outlet.

[0073] The air conditioner provided in this application embodiment has all the above-mentioned beneficial effects because it includes the air guide plate assembly 100 of any of the above embodiments, and will not be repeated here.

[0074] The air conditioner can be the indoor unit of a split-type air conditioner (such as the indoor unit of a ducted air conditioner or a wall-mounted indoor unit), or it can be a complete split-type air conditioner including both an indoor unit and an outdoor unit, or it can be an integrated air conditioner.

[0075] In some exemplary embodiments, such as Figures 6 to 8 As shown, there are multiple air vents, including a first air vent 205 and a second air vent 206. The first air vent 205 and the second air vent 206 have different air outlet directions. The first air vent 205 is configured to connect with the air duct 204 to form a first air outlet channel, and the second air vent 206 is configured to connect with the air duct 204 to form a second air outlet channel. In other words, when the first air vent 205 is connected to the air duct 204, the air outlet channel formed by their connection is the first air outlet channel. Similarly, when the second air vent 206 is connected to the air duct 204, the air outlet channel formed by their connection is the second air outlet channel.

[0076] The first air vent 205 and the second air vent 206 can be air outlets of an air conditioner, or openings inside the air conditioner located upstream of the air outlets. An indoor heat exchanger and a fan can be installed inside the air duct 204. When the fan rotates, indoor air enters the air duct 204, exchanges heat with the indoor heat exchanger, and is then discharged into the indoor space through the air outlet duct, thus regulating the temperature of the indoor air.

[0077] The number of air guide vane assemblies 100 is one or more, configured to control the opening and closing of the first air vent 205 and the second air vent 206, so that the air conditioner has: The first air outlet mode where the first air outlet channel is open and the second air outlet channel is closed (e.g.) Figure 6 and Figure 9 As shown), the second air outlet mode where the first air outlet channel is disconnected and the second air outlet channel is open (as shown). Figure 7 and Figure 10 As shown), and a third air outlet mode in which both the first and second air outlet channels are open (as shown). Figure 8 and Figure 11 (As shown).

[0078] In some embodiments, such as Figures 6 to 8 As shown, the first air outlet 205 can be a downwind outlet, discharging air downwards; the second air outlet 206 can be a side outlet, discharging air horizontally. Therefore, the first air outlet mode is the downwind air outlet mode, the second air outlet mode is the downwind air outlet mode, and the third air outlet mode is the dual air outlet mode.

[0079] like Figures 6 to 8 As shown, there are two air guide plate assemblies 100, namely a first air guide plate assembly 102 and a second air guide plate assembly 104. The first air guide plate assembly 102 and the second air guide plate assembly 104 cooperate to control the opening and closing of the first air outlet 205 and the second air outlet 206, so that the air conditioner has a first air outlet mode in which the first air outlet channel is open and the second air outlet channel is closed (e.g., Figure 6 As shown), the second air outlet mode where the first air outlet channel is disconnected and the second air outlet channel is open (as shown). Figure 7 As shown), and a third air outlet mode in which both the first and second air outlet channels are open (as shown). Figure 8 (As shown). The drive mechanism is configured to drive the first air guide plate assembly 102 and the second air guide plate assembly 104 to move relative to the housing 200.

[0080] like Figure 7 As shown, the second air vent 206 includes a first sub-air vent 2061 and a second sub-air vent 2062 that are interconnected, with the second sub-air vent 2062 located between the first air vent 205 and the first sub-air vent 2061. There are two air guide plate assemblies 100, namely a first air guide plate assembly 102 and a second air guide plate assembly 104.

[0081] The first air guide plate assembly 102 is rotatably connected to the housing 200 and is configured to rotate relative to the housing 200 between a first position where the first air vent 205 is closed and the second sub-air vent 2062 is open, a second position where the first air vent 205 and the second sub-air vent 2062 are open, and a third position where the first air vent 205 and the second sub-air vent 2062 are open.

[0082] The second air guide plate assembly 104 is rotatably connected to the housing 200 and is configured to rotate relative to the housing 200 between a fourth position where the first sub-air vent 2061 is closed and a fifth position where the first sub-air vent 2061 is open.

[0083] When the first air guide plate assembly 102 is in the third position and the second air guide plate assembly 104 is in the fourth position, the first air vent 205 opens and the second air vent 206 closes, and the air conditioner is in the first air outlet mode. Figure 6 As shown. At this time, the sealing edges of the first air guide plate assembly 102 and the second air guide plate assembly 104 overlap and seal each other, and the other parts of the edges of the first air guide plate assembly 102 and the second air guide plate assembly 104 overlap and seal with the housing 200.

[0084] When the first air guide plate assembly 102 is in the first position and the second air guide plate assembly 104 is in the fifth position, the first air vent 205 is closed and the second air vent 206 is open, and the air conditioner is in the second air outlet mode. Figure 7 As shown. At this time, the circumferential edge of the first air guide plate assembly 102 overlaps and seals with the housing 200, as shown. Figure 7 As shown.

[0085] When the first air guide plate assembly 102 is in the second position and the second air guide plate assembly 104 is in the fifth position, the first air vent 205 opens, the second air vent 206 opens, and the air conditioner is in the third air outlet mode. Figure 8 As shown.

[0086] In some exemplary embodiments, such as Figures 6 to 8 As shown, the housing 200 includes an outer shell 201, a water receiving tray 202 connected to the outer shell 201, and an air outlet frame 203 connected to the outer shell 201 and the water receiving tray 202. The air outlet frame 203 is provided with a second air outlet 206, and the water receiving tray 202 and the air outlet frame 203 together form a first air outlet 205. The first air guide plate assembly 102 and the second air guide plate assembly 104 are both rotatably connected to the air outlet frame 203.

[0087] Among them, such as Figure 7 As shown in Figure 8, the water receiving tray 202 can be located inside the outer casing 201 and below the indoor heat exchanger. The water receiving tray 202 can be connected to the bottom of the outer casing 201. The air outlet frame 203 can be located inside the outer casing 201 and connected to the front of the outer casing 201 and the top of the water receiving tray 202. The water receiving tray 202 can be provided with an air passage opening. One end (lower end) of the air outlet frame 203 near the water receiving tray 202 can be connected to the water receiving tray 202 and connected to the end of the air passage opening, so that the water receiving tray 202 and the air outlet frame 203 enclose a first air outlet 205. The lower end of the outer casing 201 can be open. The casing 200 can also include a cover plate, which covers the open end of the outer casing 201 and has a clearance opening corresponding to and communicating with the first air outlet 205.

[0088] like Figure 6As shown, in the first air outlet mode (bottom air outlet): when the first air guide plate assembly 102 and the second air guide plate assembly 104 are in their right extreme positions, the second insulation layer 3 of the first air guide plate assembly 102 abuts against the lower part of the edge 2032 of the air outlet frame 203, forming a compression seal under the torque of the motor. The second insulation layer 3, being a soft material, deforms, thus effectively sealing the air outlet. The second insulation layer 3 of the second air guide plate assembly 104 abuts against the upper part of the edge 2032 of the air outlet frame 203, forming a compression seal under the torque of the motor. The sealing step 14 of the first air guide plate assembly 102 and the sealing step 14 of the second air guide plate assembly 104 form an overlapping compression seal.

[0089] like Figure 7 As shown, in the second air outlet mode (side air outlet): when the second air guide plate assembly 104 is in the upper limit position and the first air guide plate assembly 102 is in the lower limit position, the first insulation layer 2 of the second air guide plate assembly 104 abuts against the edge 2032 of the air outlet frame 203, forming a compression seal under the torque of the motor; the first insulation layer 2 of the first air guide plate assembly 102 abuts against the water receiving tray 202 and forms a compression seal.

[0090] like Figure 8 As shown, in the third air outlet mode (dual air outlet): the second air guide plate assembly 104 is in the upper limit position and the first air guide plate assembly 102 is in the middle state, with the angle α with the horizontal plane being 30°~50°. At this time, the first air guide plate assembly 102 and the second air guide plate assembly 104 do not have a situation where one side is cold and the other side is hot, so there is no need to seal and there is no risk of condensation.

[0091] In other embodiments, the two air guide plate assemblies 100 may also control the opening and closing of the first air vent 205 and the second air vent 206 respectively.

[0092] In some other embodiments, the number of air guide plate assemblies 100 is one, and the air guide plate assembly 100 is rotatably connected to the housing 200, configured to be in a sixth position relative to the housing 200 where the first air vent 205 is open and the second air vent 206 is closed (e.g., Figure 9 As shown), open the seventh position of the first air vent 205 and the second air vent 206 (as shown). Figure 11 As shown), the eighth position where the first air vent 205 is closed and the second air vent 206 is opened (as shown). Figure 10 Rotate between (as shown) to enable the air conditioner to have a first air outlet mode (such as...). Figure 9 As shown), the second air outlet mode (such as...) Figure 10 (as shown) and the third air outlet mode (such as) Figure 11 (As shown).

[0093] Compared to the structure of two air guide plate assemblies 100, the number of air guide plate assemblies 100 in this solution is smaller, which helps to simplify the structure of the air conditioner and reduce production costs.

[0094] like Figure 9 As shown, in the first air outlet mode (downward air outlet): when the air guide plate assembly 100 is in the right extreme position, the second insulation layer 3 of the air guide plate assembly 100 abuts against the four edges 2032 of the air outlet frame 203 in the circumferential direction, forming a compression under the torque of the motor. The second insulation layer 3 is a soft material, which deforms to effectively seal.

[0095] like Figure 10 As shown, in the second air outlet mode (side air outlet): when the air guide plate assembly 100 is in the lower limit position, the first insulation layer 2 of the air guide plate assembly 100 abuts against the edge 2032 of the air outlet frame 203 and the water receiving tray 202, forming a compression seal under the torque of the motor.

[0096] like Figure 11 As shown, in the third air outlet mode (dual air outlet): the air guide plate assembly 100 is in the middle state, with an angle α between it and the horizontal plane of 30°~50°. At this time, the air guide plate assembly 100 does not have a situation where one side is cold and the other side is hot, so there is no need to seal it and there is no risk of condensation.
