[0001] This application belongs to the field of electrical technology, specifically relating to an air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure. An air conditioner has a fan assembly; the fan assembly's driver drives an impeller within a volute structure to rotate, thereby achieving airflow.

[0003] In the prior art, the volute structure consists of two volutes; however, the connection between the two volutes is prone to loosening. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an air conditioner that aims to at least partially solve the technical problem of easy loosening of the connection between the two volutes.

[0005] The technical solution of this utility model is as follows:

[0006] An air conditioner, characterized in that it comprises: a middle partition; a first volute mounted on the middle partition; a second volute detachably connected to the first volute to form a receiving cavity; an impeller disposed within the receiving cavity; and a first connector connected to the middle partition and the second volute.

[0007] Since the first volute is mounted on the intermediate partition, it can be supported by the partition. The second volute is detachably connected to the first volute to form a receiving cavity, in which the impeller is housed. Therefore, when installing the impeller, it is placed inside the first volute, and then the second volute is installed on top of it, forming a receiving cavity to house the impeller. The impeller rotates within the cavity, allowing air to enter and achieve ventilation. The first connecting piece connects the intermediate partition and the second volute, providing additional support for the installation of the second volute. This connection between the second volute and the intermediate partition ensures that the intermediate partition, the second volute, and the first volute form a stable whole, guaranteeing a tight connection between them and ensuring the stability of the connection.

[0008] In some implementations, the intermediate partition, the first volute, and the first connector are integrally formed to reduce costs.

[0009] In some implementations, the intermediate partition, the first volute, and the first connector are injection molded as a single unit to improve production efficiency.

[0010] In some embodiments, the second volute has a second connector, the first connector has a first groove, and the second connector can be embedded in the first groove to facilitate connection between the second volute and the first connector.

[0011] In some embodiments, the air conditioner further includes: a plurality of reinforcing members arranged side by side at intervals in the first groove and integrally formed with the first connector to ensure the structural strength of the first connector.

[0012] In some implementations, the reinforcing member has a second groove, and the second connector can be embedded in the second groove to reduce the contact area between the first connector and the second connector.

[0013] In some implementations, the two ends of the first connector are connected to the two opposing inner walls of the first volute to ensure the structural strength of the first volute.

[0014] In some implementations, the intermediate partition has an air vent, and the first connector has an arc-shaped transition surface that connects to the edge of the air vent to reduce wind resistance.

[0015] In some implementations, one of the first volute and the second volute is provided with a limiting member, and the other is provided with a limiting groove. The limiting member can be embedded in the limiting groove to ensure that the second volute is accurately installed on the first volute.

[0016] In some embodiments, the air conditioner further includes: a support frame and a driver disposed on the support frame, the support frame being mounted on the intermediate partition; a bearing bracket and a bearing disposed on the bearing bracket, the bearing bracket being mounted on the intermediate partition, the bearing being connected to the rotating shaft of the fan assembly, the rotating shaft being connected to the impeller and the driver; wherein the intermediate partition, the first volute, the support frame, and the bearing bracket are injection molded as a single unit to further reduce costs.

[0041] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0042] This application is described below with reference to the accompanying drawings and specific embodiments:

[0043] The air conditioner provided in this embodiment aims to solve, at least to some extent, the technical problem of air leakage caused by the loose connection between the two volutes.

[0044] Figure 1 These are schematic diagrams of the structure of an air conditioner according to some embodiments; Figure 2 for Figure 1 Front view of the central air conditioner; Figure 3 for Figure 2 A sectional view of the central air conditioner along line AA. (Combined with...) Figure 1 , Figure 2 and Figure 3The air conditioner according to this application embodiment includes: an intermediate partition 10, a first volute 20, a second volute 30, an impeller 40, and a first connecting member 50. The first volute 20 is mounted on the intermediate partition 10. The second volute 30 is detachably connected to the first volute 20 to form a receiving cavity. The impeller 40 is disposed within the receiving cavity. The first connecting member 50 is connected to the intermediate partition 10 and the second volute 30.

[0045] When the air conditioner is in use, the first volute 20 is located above the second volute 30.

[0046] Since the first volute 20 is mounted on the intermediate partition 10, it can be supported by the partition 10. Because the second volute 30 is detachably connected to the first volute 20 to form a receiving cavity, and the impeller 40 is located within this cavity, when installing the impeller 40, it is placed inside the first volute 20, and then the second volute 30 is installed on top of it to form the receiving cavity to accommodate the impeller 40. The impeller 40 rotates within the cavity, allowing air to enter and thus achieving ventilation. The first connector 50 is connected to the intermediate partition 10 and the second volute 30. Therefore, the first connector 50 connects the intermediate partition 10 and the second volute 30, providing additional support for the installation of the second volute 30. This achieves the connection between the second volute 30 and the intermediate partition 10, making the intermediate partition 10, the second volute 30 and the first volute 20 form a stable whole, ensuring a tight connection between the intermediate partition 10 and the second volute 30, and guaranteeing the stability of the connection between the first volute 20 and the second volute 30.

[0047] In some embodiments, to reduce costs, the intermediate partition 10, the first volute 20, and the first connector 50 are integrally formed, with the first volute 20 and the first connector 50 integrated onto the intermediate partition 10. That is, the intermediate partition 10 has a first volute mounting position and a first connector mounting position. The intermediate partition 10 is installed inside the air conditioner housing 110. By using only the intermediate partition 10, the assembly of the first volute 20 and the first connector 50 can be achieved, reducing the number of parts and lowering the overall cost of manufacturing, transportation, storage, and production. Furthermore, by simply installing the intermediate partition 10 inside the air conditioner housing 110, the assembly of the first volute 20 and the first connector 50 within the air conditioner housing 110 can be accomplished. This eliminates the need to install the first volute 20 and the first connector 50 inside the air conditioner casing 110, reducing assembly steps and improving production efficiency. The positions of the first volute 20 and the first connector 50 on the intermediate partition 10 are fixed, reducing assembly errors caused by assembling multiple parts and improving assembly accuracy. When the second volute 30 is connected to the first volute 20 and the first connector 50, the stability of the connection between the second volute 30 and the first volute 20 and the first connector 50 is also ensured. At the same time, the intermediate partition 10, the first volute 20 and the first connector 50 exist as a whole. During maintenance, only the intermediate partition 10 needs to be replaced, eliminating the need to separately stock multiple spare parts, reducing inventory costs, simplifying the spare parts management process, and reducing maintenance difficulty.

[0048] In some embodiments, the intermediate partition 10, the first volute 20, and the first connector 50 are integrally formed, which can achieve a seamless connection between the intermediate partition 10, the first volute 20, and the first connector 50, enhancing structural strength and improving product stability and durability. Moreover, during the manufacturing process, the intermediate partition 10 and the first volute 20 can be precisely fixed on the first connector 500, eliminating installation errors that may occur during subsequent assembly and ensuring precise fit between components, thereby improving the overall performance and reliability of the product. At the same time, the integral molding design simplifies the structure composed of the intermediate partition 10, the first volute 20, and the first connector 50 into a single component. During the production process, the manufacturing, storage, transportation, and assembly costs of multiple components can be eliminated. The reduction in the number of components directly reduces the complexity and management difficulty of the production process, thereby reducing the overall cost.

[0049] In some embodiments, to improve production efficiency, the intermediate partition 10, the first volute 20, and the first connector 50 are injection molded as a single unit. That is, the intermediate partition 10, the first volute 20, and the first connector 50 are made of plastic. Compared to sheet metal molding, because plastic can fill and replicate the shape of the mold well in the mold, injection molding can manufacture products with complex geometries and precision details, making the intermediate partition 10, the first volute 20, and the first connector 50 meet the usage requirements. Moreover, the injection molding process can achieve continuous and high-speed injection molding. The entire injection process (injection, cooling, demolding, etc.) is carried out continuously, reducing the production cycle and changeover time, and improving work efficiency. At the same time, the injection molding process can complete multiple steps in one operation, reducing the production cycle and manual intervention. It can reduce the assembly process between the intermediate partition 10, the first volute 20, and the first connector 50, and also reduce the error rate and rework rate on the assembly line, further improving production efficiency and product quality.

[0050] Figure 4 for Figure 3 Enlarged schematic diagram of point B on the central air conditioner; Figure 5 for Figure 1 A schematic diagram showing the connection between the first volute and the intermediate partition. Figure 6 for Figure 5 Enlarged diagram of point C in the diagram; Figure 8 for Figure 1 A schematic diagram of the structure of the second volute of a central air conditioner. (Combined with...) Figure 4 , Figure 5 , Figure 6 and Figure 8 In some embodiments, to facilitate the connection between the second volute 30 and the first connector 50, the second volute 30 has a second connector 301, and the first connector 50 has a first groove 501, into which the second connector 301 can be embedded. The first groove 501 can be U-shaped.

[0051] In some embodiments, in order to ensure the connection stability between the second volute 30 and the first connector 50, the second volute 30 and the second connector 301 are integrally injection molded, which can achieve a seamless connection, enhance structural strength, improve product stability and durability, and also reduce production cycle and changeover time, thereby improving work efficiency.

[0052] In some embodiments, when the second volute 30 is to be connected to the first connector 50, the second connector 301 can be embedded in the first groove 501. The operator only needs to align the second connector 301 with the opening of the first groove 501 and embed the second connector 301 into the first groove 501 to complete the connection. There is no need for complicated alignment or fixing steps, which reduces the installation difficulty and improves the installation efficiency. Moreover, the first groove 501 provides a precise guiding and positioning space for the second connector 301, ensuring that the second volute 30 can accurately dock with the first connector 50 during installation, reducing the risk of performance degradation or damage due to installation errors, and ensuring the accurate installation position of the second volute 30.

[0053] In some embodiments, the second connector 301 is embedded in the first groove 501, which can form an effective sealing interface, significantly reducing or preventing gas leakage between the intermediate partition 10 and the second volute 30, thereby improving the sealing performance.

[0054] Combination Figure 4 and Figure 6 In some embodiments, to ensure the structural strength of the first connector 50, the air conditioner further includes a reinforcing member 60. Multiple reinforcing members 60 are arranged side-by-side at intervals within the first groove 501 and are integrally formed with the first connector 50. As an additional support structure, the reinforcing members 60 can disperse and resist stress and load from the outside or inside of the first connector 50, thereby preventing the first connector 50 from deforming or breaking due to excessive force, thus ensuring the structural strength of the first connector 50.

[0055] In some embodiments, since multiple reinforcing members 60 are arranged side by side at intervals, the stress distribution inside the first connector 50 can be optimized, the stress flow can be guided to a more reasonable path, and the stress concentration phenomenon can be reduced, thereby reducing the risk of the first connector 50 being damaged due to stress concentration, further ensuring the structural strength of the first connector 50 and ensuring the safety of the first connector 50.

[0056] In some embodiments, the reinforcing member 60 and the first connecting member 50 are integrally formed, achieving a seamless connection between them. This enhances structural strength, improves product stability and durability, ensures a tight connection between the reinforcing member 60 and the first connecting member 50, improves the overall stability of the first connecting member 50, and reduces assembly operations, thereby increasing production efficiency. The reinforcing member 60 and the first connecting member 50 can be injection molded integrally.

[0057] In some embodiments, to reduce the contact area between the first connector 50 and the second connector 301, the reinforcing member 60 is provided with a second groove 601, into which the second connector 301 can be embedded. The second groove 601 of multiple reinforcing members 60 supports the second connector 301, increasing the number of support points for the second connector 301. Compared to the surface contact formed between the bottom walls of the first groove 501 of the first connector 50, the second groove 601 of multiple reinforcing members 60 forms point contact with the second connector 301. This reduces the contact area between the second connector 301 and the first connector 50 when thermal expansion and contraction occur, thus reducing the possibility of noise generated by collisions between the second connector 301 and the first connector 50 when the impeller 40 rotates, and improving the user experience. The second groove 601 can be L-shaped.

[0058] In some embodiments, the width of the second groove 601 matches the thickness of the first connector 50. When the second connector 301 is embedded in the second groove 601, it can be precisely aligned and positioned, reducing the risk of performance degradation or damage due to assembly errors, improving the accuracy and reliability of the overall assembly, and allowing the second connector 301 to fit more tightly onto the reinforcing member 60. The support of the reinforcing member 60 ensures the stability of the installation of the second connector 301.

[0059] In some embodiments, to ensure the structural strength of the first volute 20, the two ends of the first connector 50 are connected to the two opposing inner walls of the first volute 20 to form a stable support structure. This enhances the overall rigidity of the first volute 20, making it more resistant to external pressure, vibration, and deformation. Moreover, stress concentration is prone to occur in volute structures, especially when subjected to hydrodynamic loads. By having the first connector 50 span and connect the two opposing inner walls, the stress concentration points can be effectively dispersed, making the stress distribution more uniform. This reduces the risk of fatigue failure and crack propagation caused by stress concentration, making the first volute 20 less prone to deformation or damage and ensuring the service life of the first volute 20.

[0060] Combination Figure 5 and Figure 6 In some embodiments, in order to reduce wind resistance, the intermediate partition 10 has an air vent 101. The first connector 50 has an arc-shaped transition surface 502, which is connected to the edge of the air vent 101. The arc-shaped transition surface 502 allows air to flow smoothly through the air vent 101, reducing eddies and turbulence caused by abrupt changes in shape, thereby reducing the overall drag coefficient and improving the aerodynamic performance of the air conditioner. Moreover, it allows air to pass smoothly through the air vent 101, improving fluid flow efficiency, reducing energy loss, and improving the efficiency of the air conditioner.

[0061] Combination Figure 1 , Figure 5 , Figure 7 and Figure 8 In some embodiments, to ensure the precise positioning of the second volute 30 on the first volute 20, one of the first volute 20 and the second volute 30 is provided with a limiting member 303, and the other is provided with a limiting groove 201. The limiting member 303 can be embedded in the limiting groove 201 to limit the second volute 30, ensuring that the second volute 30 will not deviate from the predetermined position and angle during installation, reducing errors during installation, improving installation accuracy, and enabling the second volute 30 to be installed in place in one go without the need for multiple adjustments and corrections after installation, thereby saving installation time and improving work efficiency. Moreover, after the limiting member 303 is embedded in the limiting groove 201, the limiting member 303 abuts against the groove wall of the limiting groove 201, which can reduce displacement or loosening caused by vibration or external force, ensuring the stability of the second volute 30 installation.

[0062] In some embodiments, the second volute 30 may be provided with a limiting member 303, and the first volute 20 may have a limiting groove 201. In this case, the limiting member 303 and the second volute 30 are integrally formed. Of course, in some other embodiments, the first volute 20 may be provided with a limiting member 303, and the second volute 30 may have a limiting groove 201. In this case, the limiting member 303 and the first volute 20 are integrally formed.

[0063] Combination Figure 1 , Figure 5 , Figure 7 and Figure 8 In some embodiments, to enable the second volute 30 to be detachably connected to the first volute 20, one of the first volute 20 and the second volute 30 is provided with a buckle 202, and the other is provided with a slot 302. The buckle 202 is engaged in the slot 302. When the second volute 30 is connected to the first volute 20, the buckle 202 is engaged in the slot 302. At the same time, the second volute 30 can be limited on the first volute 20, further ensuring the accuracy of the installation position of the second volute 30. When the second volute 30 is separated from the first volute 20, the buckle 202 is separated from the slot 302, thereby realizing the separation of the second volute 30 from the first volute 20, so as to facilitate the assembly and disassembly of the second volute 30 and the first volute 20.

[0064] In some embodiments, the first volute 20 may be provided with a buckle 202, and the second volute 30 may be provided with a slot 302. Of course, in some other embodiments, the second volute 30 may be provided with a buckle 202 and the second volute 30 may be provided with a slot 302.

[0065] In some embodiments, when the buckle 202 is disposed on the first volute 20, the buckle 202 is integrally formed with the first volute 20; when the buckle 202 is disposed on the second volute 30, the buckle 202 is integrally formed with the second volute 30.

[0066] Combination Figure 1 and Figure 5 In some embodiments, to further reduce costs, the air conditioner also includes: a support frame 70, a driver 80, a bearing bracket 90, and a bearing 100. The support frame 70 and the driver 80 are mounted on the support frame 70, which is installed on the intermediate partition 10. The bearing bracket 90 and the bearing 100 are mounted on the bearing bracket 90, which is installed on the intermediate partition 10. The bearing 100 is connected to the rotating shaft 110 of the fan assembly, and the driver 80 is connected to the impeller 40. The intermediate partition 10, the first volute 20, the support frame 70, and the bearing bracket 90 are injection molded as a single unit, and the driver 80 can be a motor.

[0067] In some embodiments, since the support frame 70 and the driver 80 are disposed on the support frame 70, and the support frame 70 is mounted on the intermediate partition 10, the intermediate partition 10 supports the support frame 70, and the driver 80 can be mounted on the support frame 70. Since the bearing bracket 60 and the bearing 70 disposed on the bearing bracket 60 are mounted on the intermediate partition 10, and the bearing 70 is connected to the shaft 80 of the fan assembly, the intermediate partition 10 supports the bearing bracket 60. The bearing 70 can be mounted on the bearing bracket 60, which supports the bearing 70. The bearing 70 can support the rotating shaft 80 of the fan assembly. Since the intermediate partition 10, the first volute 20, the support frame 70, and the bearing bracket 90 are injection molded as a single unit, the support frame 70, the first volute 20, and the bearing bracket 90 are integrated on the intermediate partition 10. That is, the intermediate partition 10 has a driver mounting position, an impeller mounting position, and a bearing mounting position. The intermediate partition 10 is installed inside the housing 110 of the air conditioner. A single intermediate partition 10 can assemble the driver 80, impeller 40, and bearing 100. This means one part can secure all three components, reducing the number of parts and lowering costs across the entire manufacturing, transportation, storage, and production process. Furthermore, simply installing the intermediate partition 10 within the air conditioner's housing 110 eliminates the need to individually install the support frame 70, the first volute 20, and the bearing bracket 90 within the housing 110, reducing assembly steps and improving production efficiency. The positions of the support frame 70, the first volute 20, and the bearing bracket 90 on the intermediate partition 10 are fixed, reducing assembly errors caused by assembling multiple parts and improving assembly accuracy. Simultaneously, since the intermediate partition 10, support frame 70, first volute 20, and bearing bracket 90 exist as a single unit, only the intermediate partition 10 needs replacement during maintenance, eliminating the need to separately stock multiple spare parts, reducing inventory costs, simplifying spare parts management, and lowering maintenance difficulty.

[0068] In some embodiments, the intermediate partition 10, support frame 70, first volute 20, and bearing bracket 90 are injection molded as a single unit, enabling seamless connection between the intermediate partition 10 and the support frame 70, first volute 20, and bearing bracket 90. This enhances structural strength and improves product stability and durability. Furthermore, during manufacturing, the positions of the support frame 70, first volute 20, and bearing bracket 90 on the intermediate partition 10 can be precisely fixed, eliminating potential installation errors during subsequent assembly and ensuring precise fit between components. This improves the overall performance and reliability of the product. Simultaneously, the injection molding design simplifies the structure composed of the intermediate partition 10, support frame 70, first volute 20, and bearing bracket 90 into a single component. During production, this eliminates the manufacturing, storage, transportation, and assembly costs associated with multiple components. The reduction in the number of components directly lowers the complexity and management difficulty of the production process, thereby reducing overall costs.

[0069] Combination Figure 1 In some embodiments, when air needs to be supplied, a driver 80 is activated. The actuating end of the driver 80 drives the rotating shaft 110 to rotate, and the rotating shaft 110 drives the impeller 40 to rotate, so as to supply air. At this time, the bearing 100 supports the rotating shaft 110 to ensure the stability of the rotation of the rotating shaft 110.
