Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to an air conditioner. Background Technology

[0002] With the development of technology, ducted air conditioners have gradually been widely used.

[0003] In ducted air conditioners, a support plate is often installed inside the air intake duct to support it. The plate typically has a through hole in the middle for the rotating shaft of the fan assembly to pass through.

[0004] When assembling the aforementioned duct unit, due to the obstruction of the partition, it is necessary to first install the partition and fan assembly into the air inlet channel, and then assemble the drive shaft with the fan assembly by passing it through the shaft hole of the partition. This makes the installation of the rotating shaft extremely inconvenient. Utility Model Content

[0005] This disclosure provides an air conditioner that can solve the aforementioned technical problems existing in related technologies. The technical solution is as follows: An air conditioner is provided, the air conditioner including a housing assembly, a fan assembly and at least one support plate; The housing assembly has an air inlet channel; The fan assembly is located within the air inlet channel. The fan assembly has a support plate on at least one side in the axial direction. The support plate is connected to the housing assembly and has a first notch. The rotation axis of the fan assembly is located within the first notch.

[0006] In some possible implementations, the housing assembly includes a substrate, the support plate is connected to the substrate, and the first notch opens in a direction away from the substrate.

[0007] In some possible implementations, the support plate also has a second notch for avoiding the wiring harness.

[0008] In some possible implementations, the opening orientation of the second notch is the same as that of the first notch.

[0009] In some possible implementations, the opening of the second notch is connected to the opening of the first notch.

[0010] In some possible implementations, the support plate has a folded edge, which is at least partially located at the edge of the second notch.

[0011] In some possible implementations, the height of the second notch is less than the height of the first notch; and / or, The width of the second notch is greater than the width of the first notch.

[0012] In some possible implementations, the ratio of the height of the second notch to the height of the first notch is 0.3 to 0.5; and / or, The ratio of the width of the second notch to the width of the first notch is 1.1 to 1.5.

[0013] In some possible implementations, the surface of the support plate has multiple protrusions.

[0014] In some possible implementations, the housing assembly also has an air outlet channel inside, and the housing assembly includes a partition plate located between the air outlet channel and the air inlet channel, and connected to a first side of the support plate; The partition plate has a first positioning part on the side near the support plate, and the first side of the support plate has a second positioning part that is adapted to the first positioning part.

[0015] In some possible implementations, one of the first positioning part and the second positioning part is a positioning hole, and the other of the first positioning part and the second positioning part is a positioning protrusion.

[0016] In some possible implementations, the housing assembly includes a base plate and a return air baffle; The return air baffle has a first state or a second state. In the first state, the return air baffle is opposite to the substrate and connected to the second side of the support plate. In the second state, the return air baffle is adjacent to the substrate and connected to the third side of the support plate.

[0017] In some possible implementations, the second side of the support plate has a first flange structure, and the third side of the support plate has a second flange structure; in the first state, the first flange structure is connected to the return air baffle, and in the second state, the second flange structure is connected to the return air baffle.

[0018] In some possible implementations, the wind turbine assembly includes a volute and an impeller, the impeller being located within the volute; The air conditioner includes multiple fan assemblies, which are arranged coaxially, and the support plate is provided between the volutes of two of the fan assemblies.

[0019] In some possible implementations, the air conditioner further includes a motor located between and drivenly connected to the two fan assemblies.

[0020] The beneficial effects of the technical solution provided in this disclosure include at least the following: When assembling this air conditioner, because the first notch can avoid obstructing the installation of the rotating shaft, the support plate will not hinder its installation. Therefore, the support plate can be installed into the air inlet duct first, and the rotating shaft can be pre-installed onto the fan assembly. Then, the pre-installed fan assembly is installed into the air inlet duct. This eliminates the need to install each support plate and the fan assembly without the rotating shaft in the air inlet duct before installing the rotating shaft separately, greatly improving the convenience of rotating shaft installation.

[0025] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This disclosure provides an air conditioner. For example... Figure 1 As shown, the air conditioner includes a housing assembly 1, a fan assembly 2, and at least one support plate 3. The housing assembly 1 has an air inlet channel 101. (Combined with...) Figure 1 , Figure 2 As shown, the fan assembly 2 is located in the air inlet channel 101. The fan assembly 2 has a support plate 3 on at least one side in the axial direction. The support plate 3 is connected to the housing assembly 1, and the support plate 3 has a first notch 3a. The rotating shaft 4 of the fan assembly 2 is located in the first notch 3a.

[0028] When assembling the air conditioner provided in this embodiment, the first notch 3a can avoid obstructing the installation of the rotating shaft 4, and the support plate 3 will not hinder the installation of the rotating shaft 4. Therefore, the support plate 3 can be installed into the air inlet duct 101 first, and the rotating shaft 4 can be pre-installed onto the fan assembly 2. Then, the pre-installed fan assembly 2 can be installed into the air inlet duct 101. Thus, it is not necessary to install each support plate 3 and each fan assembly 2 without the rotating shaft 4 into the air inlet duct before separately installing the rotating shaft 4, thereby greatly improving the convenience of installing the rotating shaft 4.

[0029] In addition, by providing a support plate 3 in the air inlet channel 101 and connecting the support plate 3 to the housing assembly 1, the housing assembly 1 can be supported, thereby reducing the possibility of deformation and denting of the part of the housing assembly 1 located in the air inlet channel 101 under external force (such as squeezing or stepping).

[0030] Optionally, the support plate 3 is a sheet metal structure, and the support plate 3 is threadedly connected to the housing assembly 1.

[0031] like Figure 1As shown, in some embodiments, the fan assembly 2 includes a volute and an impeller, with the impeller located inside the volute. The air conditioner includes multiple fan assemblies 2, which are arranged coaxially, and a support plate 3 is provided between the volutes of two fan assemblies 2.

[0032] Thus, when multiple volutes are inlet, the support plate 3 can separate the volutes of the two fan assemblies 2, thereby preventing the two volutes from interfering with each other when inlet, and thus increasing the inlet efficiency and air volume.

[0033] like Figure 2 As shown, in some embodiments, the housing assembly 1 includes a base plate 11, a support plate 3 connected to the base plate 11, and a first notch 3a opening in a direction away from the base plate 11.

[0034] During the installation of the housing assembly 1, the support plate 3 can be installed on the base plate 11 first to complete the installation of the support plate 3, and the rotating shaft 4 can be pre-installed on the fan assembly 2. Then, the pre-installed fan assembly 2 is installed. During the installation of the fan assembly 2, since the first notch 3a is open in the direction away from the base plate 11, the base plate 11 will not block the first notch 3a, so the rotating shaft 4 of the fan assembly 2 can be inserted into the first notch 3a, thereby avoiding the support plate 3 from obstructing the rotating shaft 4.

[0035] Optionally, the substrate 11 can be the top plate of an air conditioner.

[0036] like Figure 2 As shown, in some embodiments, the support plate 3 also has a second notch 3b, which is used to avoid the wire harness.

[0037] The air intake duct 101 contains a wire harness. To prevent the support plate 3 from obstructing the wire harness, a clearance area needs to be provided on the support plate 3 to allow the wire harness to pass through. If the first notch 3a is used directly to allow the wire harness to pass through, it may cause the rotating shaft 4 to interfere with and become entangled with the wire harness, which may damage the wire harness.

[0038] Thus, by creating a second notch 3b on the support plate 3, the need to avoid the wire harness can be met, while reducing the possibility of the rotating shaft 4 getting tangled with the wire harness and causing damage to the wire harness.

[0039] like Figure 2 As shown, in some embodiments, the opening orientation of the second notch 3b is the same as that of the first notch 3a.

[0040] In the assembly of the air conditioner, since the first notch 3a can avoid the rotating shaft 4 and the second notch 3b can avoid the wiring harness, and since the opening direction of the second notch 3b is the same as the opening direction of the first notch 3a, the rotating shaft 4 and the wiring harness can be pre-installed on the fan assembly 2 at the same time. Then, the pre-installed fan assembly 2 is installed into the air inlet channel 101. In this process, the rotating shaft 4 can be inserted into the first notch 3a and the wiring harness can be inserted into the second notch 3b. Therefore, it is not necessary to install the wiring harness separately after all the support plates 3 and the fan assembly 2 with the rotating shaft 4 installed are installed into the air inlet channel, which can greatly improve the convenience of wiring harness installation.

[0041] like Figure 2 As shown, in some embodiments, the opening of the second notch 3b is connected to the opening of the first notch 3a.

[0042] Taking the support plate 3 as a sheet metal structure as an example, when the first notch 3a and the second notch 3b are made on the support plate 3, only one cut is needed to obtain the first notch 3a and the second notch 3b, which can greatly improve the convenience of processing the support plate 3.

[0043] like Figure 5 As shown, in some embodiments, the support plate 3 has a folded edge 303, which is at least partially located at the edge of the second notch 3b.

[0044] Thus, during the use of the support plate 3, by setting an overlapping edge 303 at the edge of the second notch 3b, the edge of the second notch 3b can be blunted, thereby preventing the edge of the second notch 3b from being too sharp and cutting the wire harness, thereby reducing the possibility of damage to the wire harness during use.

[0045] Optionally, the support plate 3 is a sheet metal structure, and the overlapping edge 303 is a sheet metal rolled edge.

[0046] like Figure 5 As shown, in some embodiments, the height h2 of the second notch 3b is less than the height h1 of the first notch 3a.

[0047] Since the first notch 3a needs to avoid the rotating shaft 4, its height h1 needs to be relatively large to accommodate this. If the height h2 of the second notch 3b is equal to or greater than the height h1 of the first notch 3a, on the one hand, the height h2 of the second notch 3b will be too large, resulting in a significant decrease in the structural strength of the support plate 3; on the other hand, when the opening of the second notch 3b connects with the opening of the first notch 3a, it may cause interference between the wiring harness and the rotating shaft 4, leading to damage.

[0048] In this way, the height h2 of the second notch 3b is less than the height h1 of the first notch 3a. This allows the wire harness to be avoided while the structural strength of the support plate 3 is not significantly reduced, and also reduces the possibility of interference and damage between the wire harness and the rotating shaft 4.

[0049] In some embodiments, the first ratio α of the height h2 of the second notch 3b to the height h1 of the first notch 3a ranges from 0.3 to 0.5.

[0050] If the value of the first ratio α is less than 0.3, the height h2 of the second notch 3b is too small, which may make it difficult for the wire harness to pass through the second notch 3b, thus making the installation of the wire harness inconvenient; if the value of the first ratio α is greater than 0.5, the height h2 of the second notch 3b is too large, which may significantly reduce the structural strength of the support plate 3, and may cause the wire harness to interfere with and be damaged by the rotating shaft 4.

[0051] Thus, the first ratio α is set to a range of 0.3 to 0.5. This ensures ease of wiring harness installation while preventing a significant decrease in the structural strength of the support plate 3, and also reduces the possibility of interference and damage between the wiring harness and the rotating shaft 4.

[0052] Optionally, the first ratio α can be 0.3, 0.35, 0.4, 0.45 or 0.5.

[0053] Optionally, the height h1 of the first notch 3a is 120mm, and the height h2 of the second notch 3b is 51mm. In this case, the first ratio α is 0.425.

[0054] like Figure 5 As shown, in some embodiments, the width d2 of the second notch 3b is greater than the width d1 of the first notch 3a.

[0055] Since the first notch 3a needs to avoid the rotating shaft 4, its width d1 only needs to be slightly larger than the diameter of the rotating shaft 4 to achieve this. If the width d2 of the second notch 3b is equal to or less than the width d1 of the first notch 3a, the width d2 of the second notch 3b will be too small. This could lead to two problems: firstly, the wire harness might have difficulty passing through the second notch 3b, making installation difficult; secondly, when the opening of the second notch 3b connects with the opening of the first notch 3a, the wire harness might come out of the second notch 3b, potentially causing interference and damage between the wire harness and the rotating shaft 4.

[0056] In this way, the width d2 of the second notch 3b is greater than the width d1 of the first notch 3a, which can improve the ease of installation of the wire harness while reducing the possibility of interference and damage between the wire harness and the rotating shaft 4.

[0057] In some embodiments, the second ratio β of the width d2 of the second notch 3b to the width d1 of the first notch 3a ranges from 1.1 to 1.5.

[0058] If the value of the second ratio β is less than 1.1, the width d2 of the second notch 3b will be too small, making it difficult for the wire harness to pass through. Furthermore, when the opening of the second notch 3b connects with the opening of the first notch 3a, the wire harness may come out of the second notch 3b, potentially causing interference and damage between the wire harness and the rotating shaft 4. If the value of the second ratio β is greater than 1.5, the width d2 of the second notch 3b will be too large, which may significantly reduce the structural strength of the support plate 3.

[0059] Thus, by setting the range of the second ratio β to 1.1~1.5, the possibility of interference and damage between the wire harness and the rotating shaft 4 can be reduced while ensuring the convenience of wire harness installation, and the possibility of a significant decrease in the structural strength of the support plate 3 can also be reduced.

[0060] Optionally, the second ratio β can be 1.1, 1.2, 1.3, 1.4 or 1.5.

[0061] Optionally, the width d1 of the first notch 3a is 46mm, and the width d2 of the second notch 3b is 60mm. In this case, the value of the second ratio β is approximately 1.3.

[0062] like Figure 6 As shown, in some embodiments, the surface of the support plate 3 has a plurality of protrusions 304.

[0063] In this way, multiple protrusions 304 can be used to increase constraints on the surface of the support plate 3, thereby improving the structural strength of the support plate 3 and reducing the possibility of bending of the support plate 3.

[0064] Combination Figure 1 , Figure 2 As shown, in some embodiments, the housing assembly 1 also has an air outlet channel 102 inside. The housing assembly 1 includes a partition 13, which is located between the air outlet channel 102 and the air inlet channel 101, and is connected to the first side of the support plate 3. Figure 2 and Figure 7 As shown, the middle partition 13 has a first positioning part 13a on the side near the support plate 3, and the first side of the support plate 3 has a second positioning part 3e that is adapted to the first positioning part 13a.

[0065] Thus, when assembling the air conditioner, the middle partition 13 and the base plate 11 are connected first, and then the support plate 3 is installed, connecting the support plate 3 to the middle partition 13. During the connection of the support plate 3 to the middle partition 13, the cooperation between the first positioning part 13a and the second positioning part 3e can be used to position the support plate 3, thereby improving the convenience of installing the support plate 3.

[0066] like Figure 7 As shown, in some embodiments, one of the first positioning part 13a and the second positioning part 3e is a positioning hole, and the other of the first positioning part 13a and the second positioning part 3e is a positioning protrusion.

[0067] In this way, the positioning of the support plate 3 and the middle partition plate 13 can be achieved through a relatively simple structure, thereby reducing the cost of positioning the support plate 3.

[0068] Optionally, the first side of the support plate 3 has a third flange structure 305, and the second positioning part 3e is a positioning hole. The positioning hole is provided on the third flange structure 305, and the third flange structure 305 is also provided with a connecting hole 3f for bolts to pass through in order to install the support plate 3. The third flange structure 305 fits against the middle partition plate 13 to improve the stability of the installation of the middle partition plate 13 and the support plate 3.

[0069] Combination Figure 3 , Figure 4 As shown, in some embodiments, the housing assembly 1 includes a base plate 11 and a return air baffle 12. The return air baffle 12 has a first state or a second state, such as... Figure 3 As shown, in the first state, the return air baffle 12 is opposite to the base plate 11 and connected to the second side of the support plate 3, as... Figure 4 As shown, in the second state, the return air baffle 12 is adjacent to the base plate 11 and connected to the third side of the support plate 3.

[0070] Among them, combined Figure 2 , Figure 3 As shown, in the first state, the air inlet of the air inlet channel 101 is opposite to the substrate 11; combined with Figure 2 , Figure 4 As shown, in the second state, the air inlet of the air inlet duct 101 is opposite to the middle partition 13. In this way, the position of the return air baffle 12 can be changed to change the opening position of the air inlet duct 101, that is, the user can change the opening position of the air inlet duct 101 according to the usage needs, thereby realizing the personalized air intake needs of the air conditioner.

[0071] like Figure 5As shown, in some embodiments, the second side of the support plate 3 has a first flange structure 301, and the third side of the support plate 3 has a second flange structure 302. In a first state, the first flange structure 301 is connected to the return air baffle 12, and in a second state, the second flange structure 302 is connected to the return air baffle 12.

[0072] Thus, in both states of the return air damper 12, the support plate 3 can be connected to the return air damper 12, that is, the return air damper 12 can be connected in both states using a single support plate 3, thereby improving the versatility of the support plate 3.

[0073] Optionally, the first flange structure 301 has a first connecting part 3c, and the second flange structure 302 has a second connecting part 3d. The first connecting part 3c and the second connecting part 3d have the same specifications and can be screw holes. The screw holes are used for bolts to pass through so that the second flange structure 302 is connected to the return air baffle 12, or the third flange structure is connected to the return air baffle 12.

[0074] Combination Figure 1 , Figure 2 As shown, in some embodiments, the air conditioner also includes a motor 5, which is located between two fan assemblies 2 and is drive-connected to the two fan assemblies 2.

[0075] In this way, one motor 5 can drive multiple fan components 2, thereby reducing the power source of the air conditioner, reducing the number of components of the fan components 2, and thus reducing the cost of air conditioner parts.

[0076] Among them, such as Figure 3 As shown, multiple fan assemblies 2 may include a first fan assembly 21, a second fan assembly 22, a third fan assembly 23, and a fourth fan assembly 24 spaced apart sequentially. At least one support plate 3 may include a first support plate 31 and a second support plate 32. The first support plate 31 is located between the first fan assembly 21 and the second fan assembly 22, and the second support plate 32 is located between the third fan assembly 23 and the fourth fan assembly 24. The motor 5 is located between the second fan assembly 22 and the third fan assembly 23. That is, the support plate 3 may not be provided between the fan assemblies 2 located on both sides of the motor 5. The motor 5 can separate the volutes of the two fan assemblies 2 to reduce the possibility of interference caused by the air intake of the volutes of the two fan assemblies 2.

[0077] In some embodiments, the air conditioner further includes a motor controller 5, which is connected to the housing assembly 1 and located on one side of the motor 5. The motor controller 5 is connected to the motor 5 via a conductive wire.

[0078] Thus, the conductive wire can pass through the second notch 3b of part of the support plate 3, while the second notch 3b in the support plate 3 located on the side of the motor 5 away from the motor 5 controller may not accommodate the wire harness.

[0079] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.

[0080] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
