DETAILED DESCRIPTION

[0045] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0046] like Figure 1-Figure 16 As shown, an embodiment of the present application provides an air guide device that can be used in an indoor unit of an air conditioner. The air guide device can open or close the air outlet of the indoor unit of the air conditioner.

[0047] like Figure 1-Figure 12 As shown, the first air guide device includes a first air guide plate 1 and a first ear 2 . The first air guide plate 1 is formed by extrusion molding, and the first ear 2 is formed by injection molding. The first ear 2 is installed on a plate surface of the first air guide plate 1 .

[0048] In the air guide device, the first air guide plate 1 is formed by extrusion molding, and the first ear 2 is formed by injection molding. The first ear 2 can be installed on a plate surface of the first air guide plate 1 (the inner plate surface of the first air guide plate 1, i.e., the airflow guiding surface for guiding the airflow), so that the first ear 2 and the first air guide plate 1 are fixed, so that the driving mechanism drives the first air guide plate 1 to rotate through the first ear 2 to realize the opening and closing of the air outlet. Since the length dimension of the first ear 2 is smaller than the length dimension of the first air guide plate 1 and the deformation is small, the first ear 2 can be formed by injection molding, and the injection-molded first ear 2 can meet the use requirements.

[0049] The first air guide plate 1 is formed by extrusion, and the interior of the first air guide plate 1 formed by extrusion is hollow, which can greatly reduce the weight of the first air guide plate 1, solve its deformation problem, and reduce the requirements for the driving mechanism (such as a stepping motor) that drives the first air guide plate 1 to rotate, which is conducive to ensuring the normal operation of the driving mechanism. The first air guide plate 1 formed by extrusion is hollow inside, and heat is isolated by the hollow layer, avoiding condensation on the outer plate surface of the first air guide plate 1.

[0050] In addition, the injection-molded first air guide plate 1 usually includes multiple parts, and the multiple parts need to be assembled and matched, which causes deformation of the parts and mutual friction during thermal expansion and contraction, resulting in abnormal noise. The extrusion-molded first air guide plate 1 is an integral part, and there is no assembly and matching, which solves the problem of abnormal noise caused by thermal expansion and contraction. The extrusion-molded first air guide plate 1 has a fast overall molding cycle and low cost. Compared with the model including the injection-molded first air guide plate 1, the embodiment of the present application can eliminate the relevant flannel (the flannel is used in the injection molding solution to isolate the abnormal noise caused by thermal barriers and contraction. The extrusion molding solution does not have assembly and does not require flannel), further reducing costs.

[0051] Therefore, the first air guide plate 1 formed by extrusion can greatly reduce the weight of the product, solve the deformation problem of the first air guide plate 1 while ensuring the normal operation of the driving mechanism, and further solve the problems of abnormal noise, condensation, etc. caused by thermal expansion and contraction.

[0052] In some exemplary embodiments, the first ear 2 is fixed to the first air guide plate 1 by ultrasonic welding.

[0053] Ultrasonic welding can greatly increase the firmness of the fixed connection between the first ear 2 and the first air guide plate 1 .

[0054] Of course, the first ear 2 and the first air guide plate 1 are not limited to being fixed by ultrasonic welding, and can also be adjusted according to actual needs.

[0055] In some exemplary embodiments, the first air guide plate 1 is provided with a first limiting structure, and the first support ear 2 is provided with a second limiting structure that cooperates with the first limiting structure to limit the position.

[0056] The first air guide plate 1 and the first support ear 2 are respectively provided with a first limiting structure and a second limiting structure. The first air guide plate 1 and the first support ear 2 can be positioned by the cooperation of the first limiting structure and the second limiting structure, so that the first support ear 2 can be subsequently fixed to the first air guide plate 1 by ultrasonic welding.

[0057] In some exemplary embodiments, Figure 10-12 As shown, the first limiting structure includes a first limiting groove 11 and a limiting rib 12 arranged in the first limiting groove 11, and the second limiting structure includes a limiting portion 21 and a second limiting groove 22 arranged in the limiting portion 21, the limiting portion 21 is accommodated in the first limiting groove 11, and the limiting rib 12 is accommodated in the second limiting groove 22.

[0058] When the first air guide plate 1 and the first support ear 2 are positioned by using the first limiting structure and the second limiting structure, the limiting portion 21 of the first support ear 2 can be placed in the first limiting groove 11 of the first air guide plate 1, so that the second limiting groove 22 provided on the limiting portion 21 can accommodate the limiting rib 12 provided in the first limiting groove 11. The first air guide plate 1 and the first support ear 2 can be positioned by the matching limiting of the limiting portion 21 and the first limiting groove 11, and the matching limiting of the second limiting groove 22 and the limiting rib 12.

[0059] In some exemplary embodiments, Figure 10-12 As shown, the first air guide plate 1 includes a first welding surface 13, the first support ear 2 includes a second welding surface 23, and the first welding surface 13 and the second welding surface 23 are welded by ultrasonic wave.

[0060] Among them: Fig.10 and Fig.12 As shown, the first ear 2 is fixed to the end of the first air guide plate 1, the first welding surface 13 is arranged outside the first limiting groove 11 and is located on the side of the first limiting groove 11 away from the middle of the first air guide plate 1, and the second welding surface 23 is located on the side of the limiting portion 21 away from the middle of the first air guide plate 1; or, as Fig.11 As shown, the first ear 2 is fixed to the middle of the first air guide plate 1 , the bottom surface of the first limiting groove 11 forms a first welding surface 13 , and the end surface of the limiting portion 21 opposite to the first welding surface 13 forms a second welding surface 23 .

[0061] On the basis of the first air guide plate 1 formed by extrusion, the first limiting structure (the first limiting groove 11 and the limiting rib 12) and the first welding surface (which can be a welding fusion surface) 13 for fixing the first ear 2 formed by injection molding are processed through post-processing, and then the first ear 2 is limited and fixed by the first limiting structure and the second limiting structure, and then the first ear 2 is fixed by ultrasonic welding. Ultrasonic welding can greatly enhance the fixed connection between the first air guide plate 1 and the first ear 2.

[0062] The injection-molded first ear 2 is designed with a second limiting structure (limiting portion 21 and second limiting groove 22) and a second welding surface (which may be a welding fusion surface) 23. During ultrasonic welding of the first air guide plate 1 and the first ear 2, the mechanical vibration energy is converted into heat energy under the action of ultrasound. When the ultrasound works, the second welding surface 23 reserved on the first ear 2 melts and fuses with the first air guide plate 1, resulting in high welding efficiency and good fixing effect.

[0063] In some exemplary embodiments, Figure 7 and Figure 8As shown, the first air guide plate 1 includes an outer air guide plate 14, an inner air guide plate 15 and a connecting rib 16. The outer air guide plate 14 and the inner air guide plate 15 are fixed, and a cavity is formed between the outer air guide plate 14 and the inner air guide plate 15; the connecting rib 16 is arranged in the cavity, and the two ends of the connecting rib 16 are respectively connected to the outer air guide plate 14 and the inner air guide plate 15.

[0064] The first air guide plate 1 formed by extrusion includes an outer air guide plate 14, an inner air guide plate 15, and a connecting rib 16 connecting the outer air guide plate 14 and the inner air guide plate 15, wherein the inner plate surface of the inner air guide plate 15 (the plate surface on the side facing away from the outer air guide plate 14) can be an airflow guiding surface. A cavity is formed between the outer air guide plate 14 and the inner air guide plate 15, so that the interior of the first air guide plate 1 is hollow, and the hollow layer can insulate heat to prevent condensation from being generated on the outer plate surface of the outer air guide plate 14 (the plate surface on the side facing away from the inner air guide plate 15).

[0065] In some exemplary embodiments, Figure 10-12 As shown, the inner air guide plate 15 of the first air guide plate 1 is provided with a notch portion 17, the notch portion 17 is connected to the cavity of the first air guide plate 1 to form a first limiting groove 11, and the limiting rib 12 is provided on the outer air guide plate 14 (as shown in FIG. Fig.10 Alternatively, the connecting rib 16 may form a limiting rib 12 (as shown in FIG. Fig.11 and Fig.12 shown).

[0066] The inner air guide plate 15 of the first air guide plate 1 is provided with a notch portion 17, which can be connected to the cavity of the first air guide plate 1 to form a first limiting groove 11, and the limiting portion 21 of the first support ear 2 can be installed in the first limiting groove 11 through the notch portion 17 to achieve limiting cooperation.

[0067] like Fig.10 As shown, the outer air guide plate 14 may be further provided with a limiting rib 12, and the limiting rib 12 may cooperate with the limiting groove of the first ear 2 for limiting; or, as shown Fig.11 and Fig.12 As shown, part of the connecting rib 16 of the first air guide plate 1 can be used as the limiting rib 12 to cooperate with the limiting groove of the first support ear 2 for limiting, which is conducive to simplifying the structure.

[0068] The outer air guide plate 14, the inner air guide plate 15, the connecting ribs 16 and the limiting ribs 12 can be an integral structure formed by extrusion, so that the first air guide plate 1 is an integral part without any assembly structure, thus avoiding deformation of the material due to thermal expansion and contraction and abnormal noise caused by mutual friction.

[0069] In some exemplary embodiments, Figure 1-Figure 8 As shown, the wind guide device further includes a second wind guide plate 3 and a second ear 4 . The second wind guide plate 3 is formed by extrusion molding, and the second ear 4 is formed by injection molding. The second ear 4 is installed on a plate surface of the second wind guide plate 3 .

[0070] The air guide device further includes a second air guide plate 3 and a second ear 4, and the second ear 4 can be mounted on a plate surface of the second air guide plate 3 (the inner plate surface of the second air guide plate 3, i.e., the airflow guiding surface for guiding the airflow), so that the second ear 4 and the second air guide plate 3 are fixed, so that the driving mechanism drives the second air guide plate 3 to rotate through the second ear 4. The opening and closing of the air outlet can be realized by the cooperation of the first air guide plate 1 and the second air guide plate 3.

[0071] The second air guide plate 3 is formed by extrusion molding, and the second ear 4 is formed by injection molding. Since the length of the second ear 4 is smaller than that of the second air guide plate 3 and the deformation is small, the second ear 4 can be formed by injection molding, and the injection-molded second ear 4 can meet the use requirements.

[0072] The second air guide plate 3 is formed by extrusion, and the second air guide plate 3 formed by extrusion is hollow inside, which can greatly reduce the weight of the second air guide plate 3, solve its deformation problem, and reduce the requirements for the driving mechanism (such as a stepping motor) that drives the second air guide plate 3 to rotate, which is conducive to ensuring the normal operation of the driving mechanism. The second air guide plate 3 formed by extrusion is hollow inside, and heat is isolated by the hollow layer, avoiding condensation on the outer plate surface of the second air guide plate 3.

[0073] In addition, the second air guide plate 3 formed by injection molding usually includes multiple parts, and multiple parts need to be assembled and matched, which causes deformation of parts and mutual friction during thermal expansion and contraction, resulting in abnormal noise. The second air guide plate 3 formed by extrusion molding is an integral part, and there is no assembly and matching, which solves the problem of abnormal noise caused by thermal expansion and contraction. The overall molding cycle of the second air guide plate 3 formed by extrusion molding is fast and the cost is low. Compared with the model including the second air guide plate 3 formed by injection molding, the embodiment of the present application can eliminate the relevant flannel (the flannel is used in the injection molding scheme to isolate the abnormal noise caused by thermal barriers and contraction. The extrusion molding scheme does not have assembly and does not require flannel), further reducing the cost.

[0074] Therefore, the use of extruded first air guide plate 1 and second air guide plate 3 can greatly reduce the weight of the product, solve the deformation problem of the first air guide plate 1 and second air guide plate 3 while ensuring the normal operation of the driving mechanism, and further solve the problems of abnormal noise, condensation, etc. caused by thermal expansion and contraction.

[0075] In some exemplary embodiments, the second ear 4 and the second air guide plate 3 are fixed by ultrasonic welding.

[0076] Ultrasonic welding can greatly increase the firmness of the fixed connection between the second support ear 4 and the second air guide plate 3 .

[0077] Of course, the second ear 4 and the second air guide plate 3 are not limited to being fixed by ultrasonic welding, and can also be adjusted according to actual needs.

[0078] In some exemplary embodiments, the second air guide plate 3 is provided with a third limiting structure, and the second support ear 4 is provided with a fourth limiting structure that cooperates with the third limiting structure for limiting.

[0079] The second air guide plate 3 and the second support ear 4 are respectively provided with a third limiting structure and a fourth limiting structure. The second air guide plate 3 and the second support ear 4 can be positioned by the cooperation and limitation of the third limiting structure and the fourth limiting structure, so that the second support ear 4 can be fixed to the second air guide plate 3 by ultrasonic welding later.

[0080] Among them, the third limiting structure and the fourth limiting structure between the second air guide plate 3 and the second support ear 4 can be set to be respectively the same as the first limiting structure and the second limiting structure between the first air guide plate 1 and the first support ear 2, so that the welding and limiting structure between the second air guide plate 3 and the second support ear 4 are consistent with the welding and limiting structure between the first air guide plate 1 and the first support ear 2. Of course, the third limiting structure can also be set to be different from the first limiting structure, and the fourth limiting structure can also be set to be different from the second limiting structure.

[0081] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the first support ear 2 and the second support ear 4 are provided in plurality, and the first support ear 2 and the second support ear 4 correspond to each other and are connected. Among them, the first support ear 2 and the second support ear 4 are provided in four, and are arranged at intervals along the length direction of the first air guide plate 1 and the second air guide plate 3. Of course, the first support ear 2 and the second support ear 4 can also be set to other numbers.

[0082] A plurality of first ears 2 and a plurality of second ears 4 are connected in one-to-one correspondence, and the shapes of the correspondingly connected first ears 2 and second ears 4 may be the same or different. A driving mechanism may be connected to the first ears 2 and the second ears 4 so as to drive the first air guide plate 1 and the second air guide plate 3 to rotate through the first ears 2 and the second ears 4, respectively, so as to open or close the air outlet. The first air guide plate 1 and the second air guide plate 3 may perform 360° circular motion along the same rotation axis.

[0083] In some exemplary embodiments, the air guide device further includes a transmission member 5, the first support ear 2 and the corresponding second support ear 4 are both anti-rotationally engaged with the transmission member 5, and the transmission member 5 is configured to be connected to a driving mechanism that drives the air guide device to rotate.

[0084] The first support ear 2 and the corresponding second support ear 4 are both anti-rotationally matched with the transmission member 5, and the transmission member 5 can be connected to the driving mechanism so that the driving mechanism drives the first support ear 2 and the first air guide plate 1 as well as the second support ear 4 and the second air guide plate 3 to rotate through the transmission member 5.

[0085] In some exemplary embodiments, Figure 1 , Figure 2 , Figure 6 , Figure 9-10 , Figure 13-Figure 15 As shown, the transmission member 5 includes a mounting portion 51 and a connecting portion 52 that are fixedly connected. The mounting portion 51 is mounted to the first ear 2. The first ear 2 and the second ear 4 are respectively provided with a first connecting hole 24 (see Fig.10 ) and a second connecting hole, the connecting portion 52 passes through the first connecting hole 24 and the second connecting hole.

[0086] Among them, one of the mounting portion 51 of the transmission member 5 and the first support ear 2 is provided with a rotation-stopping rib 25, and the other of the mounting portion 51 and the first support ear 2 is provided with a rotation-stopping groove matched with the rotation-stopping rib 25. Fig.13 As shown, the first support ear 2 is provided with two (or one or other number) anti-rotation ribs 25, and the anti-rotation ribs 25 extend along the length direction of the first air guide plate 1; the mounting portion 51 can be provided with two (or one or other number) anti-rotation grooves accordingly, and the anti-rotation cooperation between the first support ear 2 and the transmission member 5 can be achieved through the cooperation of the two anti-rotation ribs 25 and the two anti-rotation grooves, so as to prevent the transmission member 5 and the first support ear 2 from circumferential displacement. Furthermore, the first support ear 2 can also be provided with a buckle 26, so as to clamp the mounting portion 51 of the transmission member 5 through the buckle 26 (as shown in FIG. Fig.14 and Fig.15 As shown), to enhance the anti-rotation fit between the first ear 2 and the transmission member 5.

[0087] The connecting portion 52 of the transmission member 5 can pass through the first connecting hole 24 of the first support ear 2 and the second connecting hole of the second support ear 4, and Fig.10 As shown, the first connecting hole 24 and the second connecting hole are non-circular holes (such as hexagonal holes or other shapes), and the connecting portion 52 is a non-circular shape (such as hexagonal shape or other shapes) that matches the non-circular holes, so that the anti-rotation fit between the first support ear 2 and the transmission member 5, and the anti-rotation fit between the second support ear 4 and the transmission member 5 are achieved through the cooperation between the connecting portion 52 and the first connecting hole 24 and the second connecting hole.

[0088] The first support ear 2 and the second support ear 4 are both anti-rotationally matched with the transmission member 5, so that the transmission member 5 can drive the first support ear 2 and the second support ear 4 to rotate, and further drive the first air guide plate 1 and the second air guide plate 3 to rotate. In this way, when the driving mechanism drives the transmission member 5 to rotate, the transmission member 5 can drive the first air guide plate 1 and the second air guide plate 3 to rotate through the first support ear 2 and the second ear 4.

[0089] In some exemplary embodiments, Figure 6 , Figure 14-15As shown, a stop protrusion 53 is provided on the outer peripheral surface of the connecting portion 52 of the transmission member 5, and the connecting portion 52 passes through the first connecting hole 24 of the first support ear 2 and the second connecting hole of the second support ear 4 in sequence, and the stop protrusion 53 cooperates with the end face stop of the second support ear 4 away from the first support ear 2.

[0090] The outer circumferential surface of the connecting portion 52 of the transmission member 5 is provided with one or more (e.g., three or other numbers evenly distributed along the outer circumferential surface) stop protrusions 53. After the connecting portion 52 passes through the first connecting hole 24 of the first support ear 2 and the second connecting hole of the second support ear 4 in sequence, the stop protrusion 53 can cooperate with the end surface stop of the second support ear 4 away from the first support ear 2 to prevent the connection at the connecting portion 52 from being vacant and prevent the connecting portion 52 of the transmission member 5 from being detached from the first connecting hole 24 of the first support ear 2 and the second connecting hole of the second support ear 4.

[0091] In some exemplary embodiments, Figure 6 and Fig.15 As shown, the connecting portion 52 of the transmission member 5 is provided with a mounting hole 54, and the mounting hole 54 is configured for mounting Fig.16 The illustrated anti-electric shaft 6 can be connected to a drive shaft of a drive mechanism via the anti-electric shaft 6 .

In addition, since the driving shaft of the driving mechanism is a metal rod, the surface of the driving shaft is easily accompanied by electric current, and the driving shaft with electric current may cause damage to other components of the indoor unit of the air conditioner, reducing the service life. The anti-electricity shaft 6 is an insulating member, and the anti-electricity shaft 6 is provided to prevent the driving shaft with electric current from causing damage to other components of the indoor unit of the air conditioner, thereby ensuring the service life.

[0093] In some exemplary embodiments, Figure 1-Figure 3 As shown, the lengths of the first air guide plate 1 and the second air guide plate 3 can be set to be substantially equal, and substantially equal to the length of the air outlet. Figure 4-Figure 5 , Figure 7-Figure 8 As shown, the center angle of the first air guide plate 1 (relative to its rotation axis) can be set to be greater than the center angle of the second air guide plate 3 (relative to its rotation axis). Of course, the center angle of the first air guide plate 1 (relative to its rotation axis) can also be set to be less than or equal to the center angle of the second air guide plate 3 (relative to its rotation axis).

[0094] The first air guide plate 1 and the second air guide plate 3 may be arranged side by side along the width direction of the air outlet, that is, the first air guide plate 1 and the second air guide plate 3 may be arranged one above the other, such as the first air guide plate 1 may be located below the second air guide plate 3 .

[0095] An embodiment of the present application also provides an indoor unit of an air conditioner, comprising a body and an air guide device provided by any of the above embodiments, the body comprising an air outlet and a driving mechanism, the driving mechanism being connected to a first ear 2 of the air guide device to drive a first air guide plate 1 of the air guide device to rotate to open or close the air outlet.

[0096] In some exemplary embodiments, the driving mechanism is connected to the second ear 4 of the air guide device to drive the second air guide plate 3 of the air guide device to rotate, so that the first air guide plate 1 and the second air guide plate 3 cooperate to open or close the air outlet.

[0097] The air guide device may only include the first air guide plate 1 and the first ear 2, and the driving mechanism may be connected to the first ear 2 of the air guide device. In this case, the driving mechanism may drive the first air guide plate 1 to rotate through the first ear 2 to open or close the air outlet.

[0098] Alternatively, the air guide device may include a first air guide plate 1 and a second air guide plate 3 at the same time, and the driving mechanism may be connected to the first support ear 2 and the second support ear 4 of the air guide device. In this case, the driving mechanism can drive the first air guide plate 1 to rotate through the first support ear 2, and can drive the second air guide plate 3 to rotate through the second support ear 4, so that the first air guide plate 1 and the second air guide plate 3 cooperate with each other to open or close the air outlet.

[0099] An embodiment of the present application also provides an air conditioner, comprising the air conditioner indoor unit provided by any of the above embodiments.

[0100] In the embodiment of the present application, the first air guide plate 1 and the second air guide plate 3 are both extrusion molded parts, the first ear 2 and the second ear 4 are both injection molded parts, the first air guide plate 1 and the first ear 2 are fixed by ultrasonic welding after being limited by a limiting structure, and the second air guide plate 3 and the second ear 4 are fixed by ultrasonic welding after being limited by a limiting structure. The first air guide plate 1 and the second air guide plate 3 in the embodiment of the present application can perform 360° surrounding movement.

[0101] In the embodiment of the present application, the first air guide plate 1 and the second air guide plate 3 formed by extrusion are hollow as a whole, and their strength and deformation resistance are far superior to those of the first air guide plate 1 and the second air guide plate 3 formed by injection molding. If the first air guide plate 1 and the second air guide plate 3 are injection molded parts, the increased weight of the injection molded parts will increase the load of the driving mechanism (such as a stepping motor), resulting in abnormal heating of the driving mechanism; secondly, the increased weight of the injection molded parts themselves will cause the first air guide plate 1 and the second air guide plate 3 to deform, and the injection molded parts themselves will deform. Under the double deformation, the first air guide plate 1 and the second air guide plate 3 will produce abnormalities during the operation of the whole machine. The first air guide plate 1 and the second air guide plate 3 formed by extrusion can greatly reduce the weight of the first air guide plate 1 and the second air guide plate 3, while ensuring the normal operation of the driving mechanism, solving the deformation problem of the first air guide plate 1 and the second air guide plate 3, and further solving the problems of abnormal noise and condensation caused by thermal expansion and contraction.
