Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a volute air outlet reinforcement structure and an air conditioner. Background Art

[0002] For vertical cabinet air conditioner products, a cross-flow fan is usually installed in the indoor unit, a volute is installed outside the cross-flow fan, an air duct is formed between the volute and the cross-flow fan, and an air inlet and an air outlet are installed on the volute. Generally, the front panel of the vertical cabinet air conditioner is directly mounted on the air outlet of the volute. Since the front panel has a large area and thick thickness, it is heavy. The air outlet is generally made of plastic injection molding, which has limited strength and cannot stably bear the weight of the front panel for a long time.

[0003] In addition, because the vertical cabinet air conditioner is tall and heavy, and the volute is generally made of plastic, which has low hardness and strength, the volute is prone to deformation during long-term use of the air conditioner. Especially at the air outlet of the volute, due to the large hollow area and lack of strong support, it is very easy to deform and affect the normal air outlet.

[0004] Therefore, providing a volute air outlet reinforcement structure and an air conditioner to improve the strength of the volute air outlet, especially to improve the connection strength between the volute air outlet and the front panel, and to ensure stable air outlet from the volute air outlet is a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0005] The present invention improves the strength of the volute air outlet, especially improves the connection strength between the volute air outlet and the front panel, and ensures stable air outlet of the volute air outlet by designing a volute air outlet reinforcement structure and an air conditioner.

[0006] To solve the above problems, the present invention discloses a volute air outlet reinforcement structure, including a volute and a reinforcement strip, a cross-flow fan is provided in the volute, an air duct is formed between the volute and the cross-flow fan, an air inlet and an air outlet are provided on the volute, a connecting plate is provided on one side of the air outlet, and the reinforcement strip is connected to the connecting plate.

[0007] By arranging a reinforcement strip on one side of the air outlet, the strength of the air outlet is increased to prevent deformation, thereby ensuring stable air flow from the air outlet; in addition, the reinforcement strip is installed on one side of the air outlet through a connecting plate, making the installation of the reinforcement strip convenient.

[0008] Furthermore, a snail tongue is provided in the air outlet, and the air outlet has a first side and a second side that are arranged opposite to each other, the first side is on the same side as the snail tongue, and the connecting plate is arranged on the outer surface of the first side away from the snail tongue.

[0009] By arranging the connection plate on the outer surface of the first side away from the volute tongue, on the one hand, the first side of the air outlet can be supported by the reinforcement strip installed on the connection plate to improve the strength of the first side, and because the first side is the position on the air outlet that is most susceptible to airflow damage and is most susceptible to damage, reinforcing the first side can most effectively improve the overall strength of the air outlet. On the other hand, by arranging the connection plate on the outer surface of the first side, the arrangement of the connection plate and the reinforcement strip will not affect the air outlet area of ​​the air outlet.

[0010] Furthermore, the air outlet is connected to the front panel of the air conditioner through the reinforcement strip.

[0011] The air conditioner front panel is installed on the air outlet through the reinforcement strip, and the reinforcement strip bears part of the gravity of the air conditioner front panel, so that the connection between the air conditioner front panel and the air outlet is more stable and has higher connection strength.

[0012] Furthermore, the reinforcement strip is snap-connected to the connection plate.

[0013] The connection mode between the reinforcing strip and the connecting plate is set to be a snap connection, so that the reinforcing strip can be easily assembled and disassembled.

[0014] Furthermore, the reinforcing strip is a groove-shaped structure with a hollow interior, and a side of the reinforcing strip close to the connecting plate is open.

[0015] The reinforcement strip is configured as a groove-shaped structure with a hollow interior, so that the material consumption and injection molding difficulty of the reinforcement strip can be reduced.

[0016] Furthermore, the reinforcing strip is filled with soft material.

[0017] By filling the side wall of the reinforcement strip with soft material to support it, the strength of the reinforcement strip can be improved; at the same time, it can avoid the unstable connection between the reinforcement strip and the volute, which may cause abnormal noise during the operation of the air conditioner.

[0018] Furthermore, the interior of the reinforcement strip is filled with foam, and the open portion of the reinforcement strip is paved with sponge.

[0019] During use, since the hardness of foam is greater than that of sponge, filling foam inside the groove structure can effectively support the side walls of the reinforcement strip, and the elasticity of sponge is greater than that of foam, which can effectively avoid abnormal noise during the operation of the air conditioner due to unstable connection between the reinforcement strip and the volute.

[0020] Furthermore, the reinforcing strip is provided with a connecting hole, and the connecting hole is a through hole arranged on the top surface; correspondingly, a hook-shaped structure connected to the connecting hole is provided on the inner side of the front panel of the air conditioner.

[0021] By setting the connection hole, the snap connection between the front panel of the air conditioner and the reinforcement strip is realized, so that the connection between the front panel of the air conditioner and the reinforcement strip is convenient, fast and easy to operate.

[0022] Furthermore, the connecting hole includes a snap-in hole near the top of the air conditioner and a fixing hole near the bottom of the air conditioner, the opening area of ​​the snap-in hole is larger than the opening area of ​​the fixing hole, and the snap-in hole is connected to the fixing hole in a smooth transition.

[0023] By optimizing the connection hole structure, the assembly of the air conditioner front panel and the reinforcement strip is more convenient and the connection is more stable.

[0024] An air conditioner having the above-mentioned volute air outlet reinforcement structure.

[0025] The volute air outlet reinforcement structure and the air conditioner described in the present invention have the advantages of simple structure, quick installation and assembly, and can provide effective support for the volute air outlet, ensure stable air outlet of the volute air outlet and stable connection with the front panel, and ensure stable air outlet of the volute air outlet.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Embodiment 1, as Figures 1 to 6 As shown, the present invention discloses a volute air outlet reinforcement structure, including a volute 1 and a reinforcement strip 2, a cross-flow fan is arranged in the volute 1, an air duct is formed between the volute 1 and the cross-flow fan, an air inlet 15 and an air outlet 11 are arranged on the volute 1, and air can enter the cross-flow fan from the air inlet 15 and then be discharged from the air outlet 11. A connecting plate 14 is arranged on one side of the air outlet 11, and the reinforcement strip 2 is connected to the connecting plate 14.

[0036] By providing a reinforcing strip 2 on one side of the air outlet 11, the strength of the air outlet 11 is increased to prevent deformation, thereby ensuring stable air flow from the air outlet 11; in addition, the reinforcing strip 2 is installed on one side of the air outlet 11 through a connecting plate 14, so that the reinforcing strip 2 is easy to install and accurately positioned.

[0037] Furthermore, a volute tongue 16 and a sweeping blade mounting groove 17 are provided in the air outlet 11, and the air outlet 11 has a first side 12 and a second side 13 which are arranged opposite to each other, the first side 12 is on the same side as the volute tongue 16, the second side 13 is on the same side as the sweeping blade mounting groove 17, a sweeping blade is installed on the sweeping blade mounting groove 17, and the connecting plate 14 is arranged on the outer surface of the first side 12 away from the volute tongue 16, and the first side 12 and the second side 13 are parallel to the axis of the cross-flow fan.

[0038] By arranging the connecting plate 14 on the outer surface of the first side edge 12 away from the volute tongue 16, on the one hand, the first side edge 12 of the air outlet 11 can be supported by the reinforcing strip 2 installed on the connecting plate 14, thereby improving the strength of the first side edge 12. Moreover, since the first side edge 12 is the position on the air outlet 11 most strongly damaged by the airflow and is most susceptible to damage, reinforcing the first side edge 12 can most effectively improve the overall strength of the air outlet 11. On the other hand, by arranging the connecting plate 14 on the outer surface of the first side edge 12, the arrangement of the connecting plate 14 and the reinforcing strip 2 will not affect the air outlet area of ​​the air outlet 11.

[0039] Specifically, generally, in order to prevent the air from circulating in the volute 1, a volute tongue is provided on the air duct in the volute 1, and the air flow direction is changed by the volute tongue so that the air can be discharged smoothly from the air duct. Generally, the volute tongue 16 is located on the inner surface of the first side 12 relative to the air duct. On both sides of the air outlet 11, the structure of the opposite side of the volute tongue is simple, and a reinforcement structure can be formed on the opposite side of the volute tongue by integral molding. However, the structure of the side where the volute tongue is located is complex, and the injection molding difficulty itself is large, and it is difficult to form a reinforcement structure by integral molding. Therefore, a reinforcement strip needs to be provided on the side where the volute tongue is located, that is, on the first side 12, so that the strength at the air outlet 11 can be increased, which is sufficient to achieve a stable connection with the front panel.

[0040] Furthermore, the air outlet 11 is connected to the front panel of the air conditioner through the reinforcement strip 2 .

[0041] The air conditioner front panel is installed on the air outlet 11 through the reinforcement strip 2, and the reinforcement strip 2 bears part of the gravity of the air conditioner front panel, so that the connection between the air conditioner front panel and the air outlet 11 is more stable and has higher connection strength.

[0042] Furthermore, the connecting plate 14 is integrally formed with the volute 1 , and the connecting plate 14 is snap-connected with the reinforcing strip 2 .

[0043] By setting the connecting plate 14, an installation and connection structure of the reinforcing strip 2 is formed on the outer surface of the first side 12 relative to the air duct, so that the reinforcing strip 2 can be installed on the first side 12. By setting the connection mode between the connecting plate 14 and the reinforcing strip 2 as a snap connection, the reinforcing strip 2 is easy to disassemble.

[0044] Furthermore, the cross-sectional area of ​​the reinforcement strip 2 is trapezoidal, and the reinforcement strip 2 includes a top surface 21, a first side wall 22, a second side wall 23 and two end surfaces 24, the first side wall 22 and the second side wall 23 are relatively arranged on both sides of the top surface 21 along the axial direction of the cross-flow fan, and the end surfaces 24 are arranged at both ends of the top surface 21 perpendicular to the axis of the cross-flow fan.

[0045] By configuring the reinforcing strip 2 to have a trapezoidal cross section, a greater supporting force can be provided for the first side edge 12 .

[0046] Furthermore, a plug-in piece 25 is provided on the side of the first side wall 22 away from the top surface 21, and the plug-in piece 25 is a protrusion provided on the edge of the first side wall 22. Correspondingly, a card slot 142 is provided on the connecting plate 14, and the card slot 142 is a notch provided on the edge of the connecting plate 14. When the reinforcing strip 2 is assembled and connected with the connecting plate 14, the plug-in piece 25 can be inserted into the card slot 142.

[0047] By providing the plug-in piece 25 and the snap-in groove 142 , the snap-in connection between the first side wall 22 of the reinforcing strip 2 and the connecting plate 14 is achieved.

[0048] Preferably, the plug-in piece 25 is a protrusion located in the plane where the first side wall 22 is located.

[0049] By setting the plug-in piece 25 as a protrusion located in the plane where the first side wall 22 is located, and snapping the plug-in piece 25 into the slot 142, the plug-in piece 25 does not protrude from the volute 1, thereby preventing the plug-in piece 25 from being scraped off by external force or scratching other parts, and at the same time helping to improve the aesthetics of the volute 1.

[0050] Furthermore, a hook 29 is provided on the side of the second side wall 23 away from the top surface 21. Correspondingly, a hole 143 is provided on the connecting plate 14, and the hole 143 is a through hole. When the reinforcing strip 2 is assembled and connected with the connecting plate 14, the hook 29 can extend into and be fixed in the hole 143.

[0051] The hook 29 and the hole 143 are provided to realize the snap connection between the second side wall 23 and the connecting plate 14. At the same time, the hook 29 can be hidden between the reinforcing strip 2 and the volute 1, so as to avoid the hook 29 being exposed to the outside and affecting the appearance.

[0052] In addition, by setting the snap-fit ​​structures on the first side wall 22 and the second side wall 23 to be different snap-fit ​​structures, the first side wall 22 and the second side wall 23 are made asymmetrical, thereby preventing workers from installing the reinforcing strip 2 upside down during installation.

[0053] Furthermore, a side of the reinforcing strip 2 opposite to the top surface 21 is open, so that the reinforcing strip 2 is a groove-shaped structure with a hollow interior.

[0054] The reinforcement strip 2 is configured as a groove-shaped structure with a hollow interior, so that the material consumption and injection molding difficulty of the reinforcement strip 2 can be reduced.

[0055] Furthermore, the groove structure of the reinforcing strip 2 is filled with soft materials, such as foam, sponge, rubber, etc.

[0056] By filling the soft material to support the side wall of the reinforcing strip 2, the strength of the reinforcing strip 2 can be improved; at the same time, the unstable connection between the reinforcing strip 2 and the volute 1 can be avoided, which may cause abnormal noise during the operation of the air conditioner.

[0057] Furthermore, the groove structure of the reinforcing strip 2 is filled with two soft materials of different hardness. Specifically, the groove structure is filled with foam, and a layer of sponge is laid at the open part of the groove structure. During use, since the hardness of the foam is greater than that of the sponge, the foam filled in the groove structure can effectively support the side wall of the reinforcing strip 2, and the elasticity of the sponge is greater than that of the foam, which can effectively avoid the generation of abnormal noises during the operation of the air conditioner due to the unstable connection between the reinforcing strip 2 and the volute 1.

[0058] Furthermore, the reinforcing strip 2 is also connected to the connecting plate 14 by screws. Specifically, a screw hole 26 is provided on the top surface of the reinforcing strip 2, and correspondingly, a screw column 141 is provided on the connecting plate 14, and the screw column 141 and the screw hole 26 are connected by screws.

[0059] The reinforcing strip 2 is connected to the connecting plate 14 by screws, so as to ensure the connection strength and stability between the reinforcing strip 2 and the connecting plate 14, so that the reinforcing strip 2 can be tightly connected to the connecting plate 14 to avoid loosening and abnormal noise. At the same time, it is ensured that the reinforcing strip 2 can provide effective support for the first side 12.

[0060] Furthermore, a groove 28 is provided on the top surface 21 of the reinforcing strip 2 , which is sunken toward the side close to the connecting plate 14 , and the screw hole 26 is located in the groove 28 .

[0061] The arrangement of the groove 28 can improve the strength of the top surface 21, and the screw hole 26 is further arranged in the groove 28, so that the screw can be hidden in the reinforcing strip 2, thereby improving the appearance. At the same time, the assembly connection between the top surface 21 and the front panel of the air conditioner is not affected.

[0062] Furthermore, the connecting plate 14 is provided with a reinforcement groove 144, which is a recessed portion provided on the connecting plate 14. The provision of the reinforcement groove 144 can improve the strength of the connecting plate 14.

[0063] Furthermore, a connecting hole 27 is provided on the top surface 21 of the reinforcing strip 2, and the connecting hole 27 is a through hole arranged on the top surface 21. Correspondingly, a hook-shaped structure is provided on the inner side of the air-conditioning front panel. When the air-conditioning front panel is assembled and connected with the reinforcing strip 2, it is only necessary to extend the hook-shaped structure on the inner side of the air-conditioning front panel into the connecting hole 27, and then make the hook-shaped structure on the inner side of the air-conditioning front panel hook on the edge of the connecting hole 27.

[0064] By setting the connection hole 27, the snap connection between the front panel of the air conditioner and the reinforcement strip 2 is realized, so that the connection between the front panel of the air conditioner and the reinforcement strip 2 is convenient, fast and easy to operate.

[0065] Preferably, the connecting hole 27 includes a snap-in hole 271 located at one end near the top of the air conditioner and a fixing hole 272 located at one end near the bottom of the air conditioner, the opening area of ​​the snap-in hole 271 is larger than the opening area of ​​the fixing hole 272, and the snap-in hole 271 is connected to the fixing hole 272 with a smooth transition.

[0066] When the air conditioner front panel is assembled and connected with the reinforcing strip 2, firstly extend the hook-shaped structure on the inner side of the air conditioner front panel from the snap-in hole 271 into the connecting hole 27, and then the hook-shaped structure on the inner side of the air conditioner front panel will slide into the fixing hole 272 under the action of gravity, and the hook-shaped structure on the inner side of the air conditioner front panel is limited and fixed through the fixing hole 272, so that the assembly of the air conditioner front panel and the reinforcing strip 2 is more convenient and the connection is more stable.

[0067] Furthermore, the second side edge 13 is formed integrally with the volute 1. The second side edge 13 is also provided with the connection hole 27, and the air conditioner front panel is connected to the second side edge 13 through the connection hole 27.

[0070] The volute air outlet reinforcement structure and the air conditioner described in the present invention have the advantages of simple structure, quick installation and assembly, and can provide effective support for the volute air outlet 11, ensuring stable air outlet of the volute air outlet 11 and stable connection with the front panel, while effectively avoiding collision and abnormal noise between the reinforcement strip 2 and the volute 1.

[0071] Although the present invention is disclosed as above, the present invention is not limited thereto.
