[0043] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0045] In the description of the present invention, the "first feature" and "second feature" may include one or more of such features. The meaning of "a plurality" is two or more. The first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. The first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature.

[0046] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0047] Referring to Figures 1 - 6 As shown, the air conditioner 100 according to an embodiment of the present invention may include: a heat exchange component 10 and a duct component 20. Among them, the air conditioner 100 may be a double cross-flow cabinet air conditioner or the like, but is not limited thereto.

[0048] Specifically, along the air flow direction (for example Figure 4 the direction from rear to front shown in Figure 4 ), the duct component 20 is located downstream of the heat exchange component 10. The duct component 20 has a first duct 21 and a second duct 22, and the first duct 21 and the second duct 22 are spaced apart along the width direction of the duct component 20 (for example Figure 4 the left-right direction shown in

[0049] ). Thus, the duct component 20 can drive the air flow to flow through the heat exchange component 10 and flow out from the first duct 21 and the second duct 22. The heat exchange component 10 can achieve heat exchange of the air flow, meet the heat exchange requirement of the air conditioner 100 for the air flow, so that the indoor temperature can be adjusted by the air conditioner 100 to meet the user's usage requirement. Moreover, the first duct 21 and the second duct 22 are beneficial to improving the air supply volume of the air conditioner 100, improving the ability of the air conditioner 100 to adjust the indoor environmental temperature, beneficial to reducing energy consumption, improving energy efficiency, and improving the user's usage experience.

[0049] In addition, as shown in Figure 4 , Figure 5 , Figure 10With Figure 11 As shown in Figure 11 , on the sides of the first air duct 21 and the second air duct 22 facing away from each other, there is a volute tongue 23. Through the volute tongue 23, the air volume control of the first air duct 21 and the second air duct 22 can be achieved, and a noise reduction effect can be achieved.

[0050] The inventor of the present application found that in the related art, after the air duct component and the heat exchange component are assembled, there will be cavities at both ends in the width direction of the volute tongue and the heat exchange component. Airflow is likely to generate vortices in the cavities, resulting in problems such as surge abnormal noise, which affects the user experience.

[0051] Therefore, in order to solve the problem of generating surge abnormal noise, in the present invention, as Figures 4 - 6 、 Figure 10 With Figure 11 As shown in Figure 11 , the air conditioner 100 further includes a seal 30. Seals 30 are provided between the two ends in the width direction of the heat exchange component 10 (such as the left - right direction shown in Figure 4 ) and the volute tongue 23 on the same side. Through the seal 30, the gap between the volute tongue 23 and the heat exchange component 10 can be blocked, avoiding problems such as surge abnormal noise caused by air flowing into the cavity through the gap between the volute tongue 23 and the heat exchange component 10. Thus, the problem of surge abnormal noise can be effectively improved, which is beneficial to improving the user experience.

[0052] It should be noted that for the convenience of description, in the present invention, orientations such as "front", "rear", "upper", "lower", "left", and "right" are based on the orientation relationship shown in the drawings, rather than the orientation in the actual application process.

[0053] According to the air conditioner 100 of the embodiment of the present invention, the air duct component 20 has a first air duct 21 and a second air duct 22 arranged at intervals in the width direction of the air duct component 20, which is beneficial to improving the air supply volume of the air conditioner 100 and enhancing the ability of the air conditioner 100 to adjust the indoor environmental temperature. On the sides of the first air duct 21 and the second air duct 22 facing away from each other, there is a volute tongue 23. Seals 30 are provided between the two ends in the width direction of the heat exchange component 10 and the volute tongue 23 on the same side. The seal 30 can block the gap between the volute tongue 23 and the heat exchange component 10, avoiding problems such as surge abnormal noise caused by air flowing into the cavity through the gap between the volute tongue 23 and the heat exchange component 10. Thus, the problem of surge abnormal noise can be effectively improved, which is beneficial to improving the user experience.

[0054] In some embodiments of the present invention, as Figures 4 - 6 、 Figure 10 With Figure 11 ​​As shown, a sealing flange 231 is provided on one side of the volute tongue 23 facing the same-side seal 30. The sealing flange 231 extends towards the same-side seal 30. Along the air flow direction, at least a part of the sealing flange 231 is located downstream of the seal 30, and the sealing flange 231 and the seal 30 are stacked. Thus, through the cooperation of the sealing flange 231 and the seal 30, it can be further ensured that the gap between the volute tongue 23 and the heat exchange component 10 is reliably sealed, avoiding problems such as surging abnormal noise caused by air flow entering the cavity, and the structure is simple and convenient for processing and manufacturing.

[0055] In some embodiments, such as Figure 5 With Figure 11 As shown, the volute tongue 23 and the sealing flange 231 can be an integral part, which is simple to manufacture, has high connection strength, reduces the assembly process, and has high production efficiency. Of course, the volute tongue 23 and the sealing flange 231 can also be separate parts connected together, which are all within the protection scope of the present invention.

[0056] According to some embodiments of the present invention, in the stacking direction of the sealing flange 231 and the seal 30 (such as Figure 4 the front-back direction shown in

[0057] ), the distance between the sealing flange 231 and the seal 30 is 1 mm - 2 mm, which can ensure that the sealing flange 231 and the seal 30 reliably seal the cavity, avoiding problems such as surging abnormal noise caused by air flow entering the cavity through the gap between the sealing flange 231 and the seal 30, and improving the user experience. For example, in some specific embodiments, in the stacking direction of the sealing flange 231 and the seal 30, the distance between the sealing flange 231 and the seal 30 can be 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, etc.

[0058] In some embodiments, a damping member can be provided between the sealing flange 231 and the seal 30, so that the damping member can seal the gap between the sealing flange 231 and the seal 30, avoiding problems such as surging abnormal noise caused by air flow entering the cavity through the gap between the sealing flange 231 and the seal 30, and through the damping member, it can avoid problems such as resonance abnormal noise caused by the mutual collision of the sealing flange 231 and the seal 30 under the driving action of the air duct component 20, which is beneficial to improving the user experience. For example, the damping member can be sponge or flannelette, etc.

[0059] In some specific embodiments, a damping member is provided between the sealing hem 231 and the seal 30, and in the stacking direction of the sealing hem 231 and the seal 30, the distance between the sealing hem 231 and the seal 30 is 1 mm - 2 mm, facilitating the installation of the damping member in the reserved space between the sealing hem 231 and the seal 30, avoiding problems such as subsequent assembly interference, and ensuring reliable assembly.

[0060] According to some embodiments of the present invention, as Figure 6 , Figure 10 and Figure 11 shown, both sides in the width direction of the air duct component 20 have mating surfaces, and the mating surfaces are in contact with the heat exchange component 10, facilitating the assembly of the air duct component 20 and the heat exchange component 10, and ensuring reliable assembly.

[0061] In addition, as Figure 10 and Figure 11 shown, the mating surface and the sealing hem 231 are oppositely arranged in the length direction of the air duct component 20 (such as Figure 6 the up - down direction shown in

[0062] In some embodiments of the present invention, as Figure 5 shown, the seal 30 includes a connecting section 31 and an extending section 32. The connecting section 31 is connected to the heat exchange component 10, which can meet the connection requirement between the seal 30 and the heat exchange component 10, facilitating the fixation of the seal 30. The extending section 32 is connected to the connecting section 31, and the extending section 32 and the connecting section 31 form an angle with each other. The end of the extending section 32 far from the connecting section 31 extends towards the direction close to the same - side volute tongue 23, so that the extending section 32 can block the gap between the volute tongue 23 and the heat exchange component 10, avoiding problems such as surging abnormal noise caused by air flow entering the cavity through the gap between the sealing hem 231 and the seal 30, and the structure of the seal 30 is simple, facilitating processing and manufacturing.

[0063] According to some embodiments of the present invention, as Figures 6 - 9As shown, the heat exchange component 10 includes a support bracket 11 and a heat exchanger 12. The heat exchanger 12 is connected to the support bracket 11. Along the air flow direction, the air duct component 20 is located downstream of the heat exchanger 12, so that the air duct component 20 can drive the air flow through the heat exchanger 12 and flow out from the first air duct 21 and the second air duct 22. The heat exchanger 12 can realize heat exchange of the air flow, meet the heat exchange requirements of the air conditioner 100 for the air flow, and can be connected to the heat exchanger 12 through the support bracket 11, which is convenient for installing the heat exchanger 12. For example, the heat exchanger 12 can be an evaporator.

[0064] In addition, as Figures 6 - 9 shown, the seal 30 is connected to the same side of one end of each of the two ends in the width direction of the heat exchanger 12 (such as Figure 4 the left - right direction shown in the figure), which can realize the fixation of the seal 30, ensure reliable sealing of the gap between the volute tongue 23 and the heat exchange component 10, and is convenient for assembling the seal 30.

[0065] In some embodiments, as Figure 9 shown, the heat exchange component 10 further includes a temperature control component 70. The temperature control component 70 is arranged on the support bracket 11 and is located between the heat exchanger 12 and the air duct component 20. When the air conditioner 100 operates in heating mode, the temperature control component 70 can effectively improve the heating performance of the air conditioner 100 to maintain stable temperature control of the air conditioner 100 and improve the user experience. For example, the temperature control component 70 can be a Positive Temperature Coefficient Thermistor (PTC).

[0066] In some embodiments, as Figure 9 shown, there are multiple temperature control components 70. The multiple temperature control components 70 are arranged at intervals in the width direction of the heat exchanger 12. Through the multiple temperature control components 70, the heating performance of the air conditioner 100 can be effectively improved to ensure reliable temperature control of the air conditioner 100.

[0067] In the embodiments of the present invention, the number of the temperature control components 70 can be flexibly set according to the actual situation. For example, the temperature control components 70 can be Figure 9 two as shown in the figure, or three, four, five, six or more, which are all within the protection scope of the present invention.

[0068] In some embodiments of the present invention, as Figures 4 - 7 、 Figure 9 shown, side plates 121 are provided at both ends in the width direction of the heat exchanger 12. The width direction of the side plates 121 (such as Figure 4At both ends in the left - right direction (as shown) respectively have a first flanging 41 and a second flanging 42. The first flanging 41 is located on the side away from the air duct component 20 of the second flanging 42. The first flanging 41 is connected to the support bracket 11, which can realize the connection between the heat exchanger 12 and the support bracket 11. And the second flanging 42 is connected to the seal 30, which can realize the connection between the heat exchanger 12 and the seal 30. Through the side plate 121, it can make the connection between the heat exchanger 12, the support bracket 11 and the seal 30 more convenient, and the structure is simple, which is convenient for processing and manufacturing.

[0069] In some embodiments, as Figure 5 shown, the side plate 121 may include a first sub - side plate 122 and a second sub - side plate 123. Both the first sub - side plate 122 and the second sub - side plate 123 are located on the same side in the width direction of the heat exchanger 12, and the first sub - side plate 122 and the second sub - side plate 123 are staggered in the width direction of the heat exchanger 12, which can meet the requirement of the height difference needed for the connection between the side plate 121 and the end of the heat exchanger 12. One end of the first sub - side plate 122 close to the air duct component 20 has a second flanging 42, and one end of the second sub - side plate 123 away from the air duct component 20 has a first flanging 41, which can meet the connection requirements between the heat exchanger 12, the support bracket 11 and the seal 30, and the structure is simple, which is convenient for processing and manufacturing.

[0070] In some embodiments, the support bracket 11 and the first flanging 41 are connected by fasteners to ensure the reliable connection between the support bracket 11 and the first flanging 41, thereby ensuring the reliable connection between the support bracket 11 and the heat exchanger 12, and it is also convenient for disassembly, which is beneficial to reducing production costs. For example, the fasteners can be screws, etc.

[0071] In some embodiments, the seal 30 and the second flanging 42 are connected by fasteners to ensure the reliable connection between the seal 30 and the second flanging 42, thereby ensuring the reliable connection between the seal 30 and the heat exchanger 12, and it is also convenient for disassembly, which is beneficial to reducing production costs.

[0072] In some embodiments, the support bracket 11 and the first flanging 41 are connected by fasteners, and the seal 30 and the second flanging 42 are connected by fasteners, making the connection between the support bracket 11 and the first flanging 41, and the connection between the seal 30 and the second flanging 42 reliable, which can ensure the reliable connection between the support bracket 11, the seal 30 and the heat exchanger 12, and it is also convenient for disassembly, which is beneficial to reducing production costs.

[0073] In some specific embodiments, as Figure 9As shown, a first connection hole 112 is provided on the support bracket 11. The first flanging 41 is provided with a second connection hole, and the second flanging 42 is provided with a third connection hole 421. By passing a fastener through the first connection hole 112 and the second connection hole, the support bracket 11 can be connected to the first flanging 41, ensuring a reliable connection between the support bracket 11 and the first flanging 41. By passing a fastener through the side plate 121 and the third connection hole 421, the seal 30 can be connected to the second flanging 42, ensuring a reliable connection between the seal 30 and the second flanging 42.

[0074] In some embodiments, as Figure 9 shown, there may be a plurality of first connection holes 112. The plurality of first connection holes 112 are spaced apart in the height direction of the support bracket 11 (for example, Figure 6 the up and down direction shown in the figure). The first flanging 41 is provided with second connection holes corresponding to the first connection holes 112 one by one. By passing a plurality of fasteners through the first connection holes 112 and the second connection holes respectively, connections at multiple different positions between the support bracket 11 and the first flanging 41 can be achieved, ensuring a reliable connection between the support bracket 11 and the first flanging 41.

[0075] In the embodiments of the present invention, the number of the first connection holes 112 can be flexibly set according to the actual situation. For example, the first connection holes 112 can be Figure 9 as shown, three in number, or two, four, five, six or more, all of which are within the protection scope of the present invention.

[0076] In some embodiments, as Figure 9 shown, there may be a plurality of third connection holes 421. The plurality of third connection holes are spaced apart in the height direction of the second flanging 42 (for example, Figure 6 the up and down direction shown in the figure). By connecting the seal 30 to multiple different positions of the second flanging 42, a reliable connection between the seal 30 and the second flanging 42 is ensured.

[0077] In the embodiments of the present invention, the number of the third connection holes 421 can be flexibly set according to the actual situation. For example, the third connection holes 421 can be Figure 9 as shown, three in number, or two, four, five, six or more, all of which are within the protection scope of the present invention.

[0078] According to some embodiments of the present invention, as Figures 6 - 11As shown, the inner wall surface of the support bracket 11 is formed into an arc shape. There are limiting grooves 111 on both inner side walls of the support bracket 11 opposite to each other in the width direction. At both ends of the air duct component 20 in the width direction, there are limiting protrusions 26. Thus, through the cooperation of the limiting protrusions 26 and the limiting grooves 111, the support bracket 11 and the air duct component 20 can be closely fitted, effectively reducing the air flow from flowing out through the connection between the support bracket 11 and the air duct component 20, and ensuring the reliable operation of the air conditioner 100.

[0079] Meanwhile, as Figure 7 shown, in the length direction of the support bracket 11, the limiting groove 111 penetrates through the support bracket 11, and the side of the limiting groove 111 facing the air duct component 20 (for example, Figure 4 the front side shown in

[0080] is open), which is convenient for the limiting protrusion 26 to extend into the limiting groove 111, making the installation of the air duct component 20 and the support bracket 11 more convenient, conducive to improving the assembly efficiency, and having a simple structure and being convenient for processing and manufacturing. Figure 8 and Figure 11 shown, the outer peripheral wall of the limiting protrusion 26 is formed into a mating surface. The limiting protrusion 26 and the sealing folded edge 231 are arranged opposite to each other in the length direction of the air duct component 20, and the free end of the sealing folded edge 231 retracts into the limiting protrusion 26 on the same side. Thus, during the installation of the air duct component 20 and the heat exchange component 10, while the limiting protrusion 26 cooperates with the limiting groove 111, it can avoid problems such as the sealing folded edge 231 exceeding the limiting protrusion 26 and colliding with the tube assembly 13 of the evaporation component, ensuring reliable assembly.

[0081] In some embodiments of the present invention, as Figures 4 - 6 , Figure 10 and Figure 11 shown, the air duct component 20 includes a wind wheel 201 and an air duct member 202. The air duct member 202 defines a first air duct 21 and a second air duct 22. Wind wheels 201 are provided in both the first air duct 21 and the second air duct 22. The wind wheel 201 in the first air duct 21 can drive the air flow to flow through the heat exchange component 10 and flow out from the first air duct 21, and the wind wheel 201 in the second air duct 22 can drive the air flow to flow through the heat exchange component 10 and flow out from the second air duct 22, meeting the required heat exchange requirements. In addition, a volute tongue 23 is provided on the air duct member 202, which is convenient for processing and manufacturing the volute tongue 23. For example, the wind wheel 201 can be a cross-flow wind wheel 201.

[0082] In some embodiments, as Figure 6 , Figure 10 and Figure 11As shown, the air duct member 202 includes a first volute 24 and a second volute 25, the first volute 24 and the second volute 25 are connected to each other, the first volute 24 and the second volute 25 jointly define a first air duct 21 and a second air duct 22, the wind wheel 201 is arranged between the first volute 24 and the second volute 25, and the volute tongue 23 is arranged on the first volute 24, so that the structure of the air duct member 202 is simple and easy to process and manufacture.

[0083] According to some embodiments of the present invention, Figure 5 As shown, in the width direction of the air duct component 20, the minimum distance between the end of the seal 30 close to the volute tongue 23 and the wind wheel 201 on the same side is greater than 5mm, that is, in the width direction of the air duct component 20, the minimum distance between the end of the seal 30 close to the volute tongue 23 and the wind wheel 201 on the same side is L and satisfies L>5mm. Therefore, when the air duct component 20 and the heat exchange component 10 are assembled, it is possible to avoid problems such as collision between the air duct component 202 and the wind wheel 201, and ensure reliable assembly. For example, in some specific embodiments, in the width direction of the air duct component 20, the minimum distance between the end of the seal 30 close to the volute tongue 23 and the wind wheel 201 on the same side can be 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc.

[0084] In some embodiments, Figure 12 and Figure 13 As shown, in the length direction of the duct component 20, the distance between the end surface of the first duct 21 along the length direction of the duct component 20 and the seal 30 on the same side is greater than 5mm, that is, in the length direction of the duct component 20, the distance between the end surface of the first duct 21 along the length direction of the duct component 20 and the seal 30 on the same side is H and satisfies H>5mm. Therefore, when the duct component 20 and the heat exchange component 10 are assembled, it is possible to prevent the end surface of the first duct 21 along the length direction of the duct component 20 from colliding with the seal 30, thereby ensuring reliable assembly. For example, in some specific embodiments, in the length direction of the duct component 20, the distance between the end surface of the first duct 21 along the length direction of the duct component 20 and the seal 30 on the same side can be 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc.

[0085] In some embodiments, in the longitudinal direction of the air duct component 20, the distance between the end face of the second air duct 22 along the longitudinal direction of the air duct component 20 and the sealing member 30 on the same side is greater than 5 mm. That is, in the longitudinal direction of the air duct component 20, the distance between the end face of the second air duct 22 along the longitudinal direction of the air duct component 20 and the sealing member 30 on the same side is H and satisfies H > 5 mm. Thus, when the air duct component 20 and the heat exchange component 10 are assembled, problems such as collision between the end face of the second air duct 22 along the longitudinal direction of the air duct component 20 and the sealing member 30 can be prevented, ensuring reliable assembly. For example, in some specific embodiments, in the longitudinal direction of the air duct component 20, the distance between the end face of the second air duct 22 along the longitudinal direction of the air duct component 20 and the sealing member 30 on the same side can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, etc.

[0086] In some embodiments, as Figures 1 - 4 shown, the air conditioner 100 includes a housing 50. Both the heat exchange component 10 and the air duct component 20 are located inside the housing 50.

[0087] In addition, as Figures 1 - 4 shown, the housing 50 has an air inlet 51, a first air outlet 52, and a second air outlet 58. The first air duct 21 is opposite to the first air outlet 52, and the second air duct 22 is opposite to the second air outlet 58. When the air conditioner 100 is operating, the air duct component 20 can drive the outdoor air flow to enter the housing 50 through the air inlet 51. The air flow inside the housing 50 can exchange heat with the heat exchange component 10. A part of the heat-exchanged air flow can be blown into the room through the first air duct 21 and the first air outlet 52, and another part of the heat-exchanged air flow can be blown into the room through the second air duct 22 and the second air outlet 58, which can adjust the indoor temperature, has a large air supply volume, and meets the user's usage requirements.

[0088] In some embodiments, as Figures 1 - 3 shown, the housing 50 may include a top cover 53, a panel assembly 54, a back plate 55, and a chassis 56.

[0089] In some embodiments, as Figures 1 - 3 shown, the panel assembly 54 may include a first panel 541 and a second panel 542. The first panel 541 and the second panel 542 are connected, which is beneficial to reducing the complexity of the overall processing of the panel assembly 54, facilitating the processing and manufacturing of the panel assembly 54, and is beneficial to reducing production costs.

[0090] In some embodiments, such as Figure 2 As Figure 4 shown, the air conditioner 100 further includes an air outlet frame 60. The air outlet frame 60 is disposed in the housing 50. On both sides in the width direction of the air outlet frame 60 (for example, the left - right direction shown in Figure 4 ), a first switch door and a second switch door are respectively provided. The first switch door and the second switch door are respectively movably disposed at the first air outlet 52 and the second air outlet 58. The first switch door and the second switch door can respectively open or close the first air outlet 52 and the second air outlet 58. The air outlet frame 60 facilitates the installation of the first switch door and the second switch door, ensuring that the first switch door and the second switch door are fixedly reliable.

[0091] In some embodiments, such as Figure 2 As Figure 4 shown, an air inlet grille 57 is provided at the air inlet 51. The air inlet grille 57 can prevent insects, mice, etc. from entering the housing 50 of the air - handling device, causing damage to the air - handling device, ensuring the normal operation of the air - handling device, and ensuring good appearance.

[0092] In some embodiments, such as Figure 2 As Figure 4 shown, the air inlet grille 57 can be disposed opposite to the air duct component 20, facilitating the air duct component 20 to drive the outdoor air flow to enter the housing 50 through the air inlet grille 57, making the air flow smoother, increasing the air intake volume, improving the air intake efficiency of the air duct component 20, reducing the noise during the operation of the air conditioner 100, and enhancing the performance and comfort of the air conditioner 100.
